Cross-Mapping Tableau Prep Workflows into Power Query: A Developer’s Blueprint

When migrating from Tableau to Power BI, one of the most technically nuanced challenges is translating Tableau Prep workflows into Power Query in Power BI. Both tools are built for data shaping and preparation, but they differ significantly in structure, functionality, and logic execution. For developers and BI engineers, mastering this cross-mapping process is essential to preserve the integrity of ETL pipelines during the migration. This blog offers a developer-centric blueprint to help you navigate this transition with clarity and precision.

Understanding the Core Differences

At a foundational level, Tableau Prep focuses on a flow-based, visual paradigm where data steps are connected in a linear or branching path. Power Query, meanwhile, operates in a functional, stepwise M code environment. While both support similar operations—joins, filters, aggregations, data type conversions—the implementation logic varies.

In Tableau Prep:

Actions are visual and sequential (Clean, Join, Output).

Operations are visually displayed in a flow pane.

Users rely heavily on drag-and-drop transformations.

In Power Query:

Transformations are recorded as a series of applied steps using the M language.

Logic is encapsulated within functional scripts.

The interface supports formula-based flexibility.

Step-by-Step Mapping Blueprint

Here’s how developers can strategically cross-map common Tableau Prep components into Power Query steps:

1. Data Input Sources

Tableau Prep: Uses connectors or extracts to pull from databases, Excel, or flat files.

Power Query Equivalent: Use “Get Data” with the appropriate connector (SQL Server, Excel, Web, etc.) and configure using the Navigator pane.

✅ Developer Tip: Ensure all parameters and credentials are migrated securely to avoid broken connections during refresh.

2. Cleaning and Shaping Data

Tableau Prep Actions: Rename fields, remove nulls, change types, etc.

Power Query Steps: Use commands like Table.RenameColumns, Table.SelectRows, and Table.TransformColumnTypes.

✅ Example: Tableau Prep’s “Change Data Type” ↪ Power Query:

mCopy

Edit

Table.TransformColumnTypes(Source,{{"Date", type date}})

3. Joins and Unions

Tableau Prep: Visual Join nodes with configurations (Inner, Left, Right).

Power Query: Use Table.Join or the Merge Queries feature.

✅ Equivalent Code Snippet:

mCopy

Edit

Table.NestedJoin(TableA, {"ID"}, TableB, {"ID"}, "NewColumn", JoinKind.Inner)

4. Calculated Fields / Derived Columns

Tableau Prep: Create Calculated Fields using simple functions or logic.

Power Query: Use “Add Column” > “Custom Column” and M code logic.

✅ Tableau Formula Example: IF [Sales] > 100 THEN "High" ELSE "Low" ↪ Power Query:

mCopy

Edit

if [Sales] > 100 then "High" else "Low"

5. Output to Destination

Tableau Prep: Output to .hyper, Tableau Server, or file.

Power BI: Load to Power BI Data Model or export via Power Query Editor to Excel or CSV.

✅ Developer Note: In Power BI, outputs are loaded to the model; no need for manual exports unless specified.

Best Practices for Developers

Modularize: Break complex Prep flows into multiple Power Query queries to enhance maintainability.

Comment Your Code: Use // to annotate M code for easier debugging and team collaboration.

Use Parameters: Replace hardcoded values with Power BI parameters to improve reusability.

Optimize for Performance: Apply filters early in Power Query to reduce data volume.

Final Thoughts

Migrating from Tableau Prep to Power Query isn’t just a copy-paste process—it requires thoughtful mapping and a clear understanding of both platforms’ paradigms. With this blueprint, developers can preserve logic, reduce data preparation errors, and ensure consistency across systems. Embrace this cross-mapping journey as an opportunity to streamline and modernize your BI workflows.

And control components are able to entirely dictate the connection of different models and view components. MVC makes it easier for developers to manage UI codes and databases.

8. Better number of flexibility in apps.

The framework for AngularJS comes with different special designs for architectural purposes and for improving the server performance. AngularJS framework is also very convenient to use for app development. This is the main reason behind angularJS software systems popularity among developers and programmers.

9. Security in AngularJS framework.

No matter what you are doing or where you are, security is one of the main concerns. Even while developing an application, security is a big concern. Any kind of security breach can cause the company a ton of money and data malfunctions. No one can afford to take a risk this big. But when you use AngularJS from developing web software systems, you use representative state transfer systems, APIS, etc for the HTTPS interface. This is to connect various servers to interact and offer data and app protection from viruses and threats.

Conclusion

AngularJS framework comes with has made the lives of developers much easier. AngularJS is one of the most important frameworks of JavaScript and has huge benefits for its users, businesses and developers. Using angularJS in your software systems can help improve the performance of web pages and sites. You can also grow your business to the next level with the help of this coding tool. You can hire dedicated angular JS team in the USA, Canada, UAE, Saudi Arabia, etc. These teams will help you understand and simplify the entire software development process better.

reMarkable 2 Review

I had some requests for a review of this device, and I am glad to oblige in this case. I've been closely following digital pen stylus tech for about eight years. I'm just old enough that I still need to handwrite a lot of things to tap into my creativity, but greatly dislike clutter in my life.

The reMarkable is for the person that writes enough by hand to fill several notebooks a year. For someone that wants the tactile and somatic component of writing on paper to associate with their process. The new reMarkable 2 does basically what the reMarkable 1 did; faster, better, and with a much improved piece of hardware.

If you've read my previous review from May 2018, you know I basically raved about the first generation reMarkable. I had a few criticisms of the Gen 1, and a lot of that has been addressed with the Gen 2.

Support & User Experience

I've used a reMarkable tablet continuously for almost three years. I've never had a support issue with one. The software is updated regularly, features added, and user experience improved with each iteration.

There is really no comparisons to be made with that kind of uninterrupted usage. No smartphone, tablet, or computer you ever own will be that reliable. A 3-4 year old Thinkpad, running Linux, is about as close as it gets to that level of, switch-on-and-use, every day, without fail feeling.  

The reason is that the reMarkable 2 is leveraging the most reliable hardware, user input methods, stylus technology, and operating system basis available. My fear has always been that my reMarkable wouldn't be as reliable as a regular piece of paper, and a good pen. So far, that fear has never been realized with the reMarkable 1, or 2.

Pen Stylus Input

The majority of what one picks up and uses will be Microsoft Pen Protocol (MPP) stylus tech, with Microsoft Surface Products, or Wacom AES (Active Electrostatic) like that found in a lot of Asus, Dell, Lenovo, and so forth. The older Wacom EMR (Electromagnetic Resonance) is used less frequently, and usually only with their own products, or a version thereof with Samsung Phones and Tablets.

Of the three options, Wacom's EMR is still the best.

That's what you'll find on the reMarkable Tablet, and if you get their Marker Plus (it's the black one) it has the magical EMR eraser tip opposite the drawing point. There is no better pen stylus experience, for general use, sketching, handwriting capture, tilt sensitivity, and so forth.

The Marker Plus is $50 more than the regular Marker. It is worth it.

What if you're like me, and you have a drawer full of pen stylus products? Products that include the legendary Excalibur stylus pen that came with the Thinkpad Tablet 10 Gen 1, and worked with the EMR capable Thinkpad Yoga S1 from 2013? The one with the eraser tip, and sweet felt tip point? Will that stylus work?

Yes. Yes, yes it will.

However, the reMarkable Marker Plus just feels better. It's heft (19g) is perfect, eraser tip rounded to feel like the real thing, and tips that degrade gracefully without marking up the screen. Buy. The. Marker. Plus.

The Hardware

The manufacturer says that the reMarkable 2 gets 3 times the battery life of the 1, is 2 times as responsive (relative to rendering digital ink), and is the world's thinnest tablet at 0.19". Mostly, this is all of this seems to be true. Also, as mentioned before all the new Marker Plus has a built in eraser, all the new accessories snap together with magnets, and it charges with USB-c.

The screen is capacitive touch capable now. No more page turning buttons, and you can swipe down from the top to back out of a document or folder. You can turn pages with the swipe of a finger now. It takes a second to get the gestures down, but they're crisp and reliable once you do.

The tablet runs off of a dual core ARM process (a good thing, in my opinion).

My only quibble is that it is supposed to be able to connect to both 2.4GHz and 5.0GHz WiFi, but so far I've only gotten it to connect to 2.4. It might be something with my specific router, and I'm not sure if my experience is typical.

On the lower left hand side of the tablet there are 5 connection points. This suggests that the tablet may have the ability to connect to other accessories in the future. If reMarkable added a Plain Text Editor, and a keyboard cover to the reMarkable, I would be over the moon.

There is no evidence that they will do this, but a guy can dream. Having what's basically an e Ink Typewriter this thin and light would be the ultimate for this writer.

The Software

It is much the same experience as the reMarkable 1 with a few new additions.

You can convert your handwritten notes into text, cursive or block letters, and share by email. There is support for 33 languages.

With a Google Chrome plug-in, you can read web articles and pages on your reMarkable. If you're already battling with eye strain from looking at glowing screens all day, this is a nice feature.

Reading large PDFs and eBooks is still not crisp and snappy, but it is a vastly improved experience when compared to the reMarkable 1. Large graphically intense documents can be navigated without it taxing your patience. What I store on my reMarkable is vastly different now because of how much improved document handling has become.

I find the small sacrifice in speed rendering pages worth it, compared to the eye strain I get reading on other screens.

More pens, features, page templates, and ease of organizing have been added incrementally over time. With regard to the core functioning (Linux Based Codex OS) of the device, the manufacturer has only ever improved and supported the reMarkable.

Aesthetics

The reMarkable 1 was good for what it could do. It wasn't a bad looking product, but compared to the reMarkable 2, it was a rough prototype. Most tablets do not feel as nice in the hand as the reMarkable 2.

Rubber no-slip nubs on the back, rounded edges, satin finished glass and aluminum, make the tablet itself feel like it's from the future. I bought the Polymer Weave Book Folio, a step up from the regular Folio. A close friend got the same device and marker options as I did, but opted for the Premium Leather Folio.

Definitely, get the Book Folio, and if you can scrabble together the extra money, get the premium leather. That's my only regret is that I didn't spring for the best accessory offered. Is the Polymer Weave good? Absolutely, worth the $99. It is rigid, will protect your investment, and it's very classy looking.

My friend who picked up the Leather Folio is a graphic designer, and has greatly informed my sense of aesthetics over the years. She says the Leather Book Folio is well worth the extra. She is, most certainly, correct.

So, yeah, if you're going to get a reMarkable 2 and want a slightly used Polymer Weave Book Folio (mine), I'll let it go for cheap (so I can atone, and get the leather version, ha ha).

Value

The reMarkable 2 doesn't have a web browser, app store, Merge Dragons, audio player, or other third party applications. It won't replace your iPad, or Android Tablet. It will replace all the paper, notebooks, and pens in your life. This is especially true if you have a small scanner (like a Doxie), and leverage reMarkable's Smartphone app and cloud sync feature.

This tablet is for people that like paper, a lot, but don't want to carry it around or keep track of it. It is for people that fill 8-12 Moleskines a year, and mark up hundreds of pages of documents, for themselves, and others. It is for people that tap into their creativity by writing things down, sketching diagrams, and making lists.

The act of holding a pen or pencil against paper is a cognitive trigger, built into their implicit memory, every day, for years, that allows them to do their things.

$399 will buy a decent Samsung or Apple branded tablet, but neither of those is designed to emulate the experience of writing on paper like the reMarkable 2 tablet is. The reMarkable 2 will run you $399, a Marker Plus $99, and a Polymer Weave Folio $99, bringing it all to almost $600.

Unless you lurk reMarkable's website, and wait for a promotion. They did run a promotion for their pre-order, and will likely do something similar within a year of release. It is my recollection that the manufacturer ran at least two promotions for the Remarkable 1, and the savings were significant.

If you don't need one right this minute, check the website every week or so, their Amazon Store edifice, and whatever other options they have for your region.

Competitors

In the last few years, reMarkable has only acquired more competition in the e ink Tablet market. That competition varies depending on where you live in the world. In the US, no one makes a thing that directly competes. I looked at other products, didn't see anything that made me pull out my reMarkable 1 and make a list of pros and cons for comparison.

That isn't to say there isn't a better thing for your use case, but there wasn't for mine.

Final Thoughts

If I didn't drive this point home earlier, I'm going to make it now. The reMarkable 2 will not replace your laptop, mobile OS (iOS/Android) Tablet Device (meant to replace your laptop), or Smartphone. There isn't even a calculator app on the reMarkable 2.

The Remarkable 2 will replace the pens, pencils, highlighters, notebooks, and print outs cluttering up your daily carry bag, desk, and life. It's a digital paper option, not a personal computing option. When used for that purpose, it is exceptional, and well worth the investment.

A Microchip PIC based USB sound card

INTRODUCTION

The idea for creating a USB sound card based on a PIC came from discussions of other people creating one on the Microchip USB forum. The hardware of the card is based on all Microchip products. The software uses a modified version of the Microchip USB framework which is interrupt driven instead of the traditional polling. The device is a USB composite device. The first device is an implementation of the USB Audio 1.0 interface and the other device is a custom interface based on a HID interface. The purpose of the custom interface is for programming the device serial number, upgrading the firmware, and in the future any other configuration that isn’t supported directly by USB Audio 1.0. In a previous version, WinHTTP was oringally used. After testing the card for awhile, I decided it's better to not require drivers for the card especially since the HID/WinUSB interface is rarely used.

The sound card runs at a sample rate of 48KHz, 32KHz or 24KHz selectable by the OS with 12 bits per sample. The quality approaches commercial grade as the sample rate is higher then CDs. 44.1KHz was not implemented due to the difficultly and additional processing overhead. The sample rates that were implemented are all a multiple of the 1ms USB frame meaning each frame sends the same amount of data. 44.1KHz requires the card to handle different amounts of data each frame requiring more advanced buffering and synchronization techniques and more processing power. Microsoft Windows automatically resamples the 44.1KHz audio found on CDs to 48KHz.

USB Audio Streamer V1.2

HARDWARE

Click for enlarge Schematic for USB Audio Streamer V1.2

The hardware for the sound card is based on the Microchip PIC18F2550 USB processor. The processor is clocked at 48MHz which is the maximum rate for this processor and is also a multiple of the audio sample rate. The microcontroller is connected via the SPI port to duel Microchip MCP4822 12bit D/A converters. Volume control is implemented by the Microchip MCP41010 variable res-- ders are controlled via SPI by the microcontroller via a dedicated bit-banged SPI port. The purpose of using a separate port is so that volume control can run inside the processor at a different priority level then sample output. The Microchip MCP6022 op-amp is used as an output driver.

The MCP6022 op-amp has an output drive capacity large enough to power a pair of cheap headphones without much distortion. The resistance of my headphones is approximately 25ohms. The op-amps are not powerful enough to drive speakers which are usually 8 or 4 ohms. The MCP41010 and MCP6022 can output near rail to rail voltage although some nonlinear effects can be heard if the volume is too loud or the signal is near the minimum or maximum. Since USB has a single rail 5V power supply, the sound card only uses a positive rail instead of a traditional duel rail system which is how standard 16bit PCM is encoded. As a result, the signal needs to be biased in software to 2.5V.

One terminal of the MCP41010 is connected to the signal for that channel and the other terminal is connected to the midpoint or bias voltage. Previous versions of this sound card connected the second terminal to GND. The advantage of connecting the terminal to the bias is that as the volume is changed, the signal grows or shrinks around the midpoint rather then shifting toward GND. The signal is kept as far away from the rails as possible.

SOFTWARE

The software for USB Audio Streamer is composed of several components. These are the audio card firmware, a C++ library that wraps HID and WinUSB, and a command line utility for flashing. I am giving out the source code as a learning tool for other people. I don’t care what you do with it but I am not responsible for any damage that might happen from using it. NOTE: Improper use of hardware or software may cause serious injury or death.:)

I use Visual Studio 2005 Professional but I have heard that the project will build with Visual Studio Express. To build the project it is necessary to download the latest version of the WDK to get the headers and library files for HID and WinUSB. The default directories in Visual studio need to be modified to point to the directories of these resources in the WDK. If you use Visual Studio Express it's necessary to recreate all the project files and change the default calling convention to _stdcall.

DirectoryFunctionincGeneral Include DirectorybootBoot Loader(Build first)audiostreamSound card firmwareusbdevprogramerProgrammer command line utility(Build last)

Source Code Modules

A trick is used when building the sound card firmware since it is two separate projects that need to be merged together. Build the boot directory first, which is the code responsible for upgrading the firmware. Then build the sound card firmware itself. Before flashing, goto Configure/Settings/Program Loading and clear the option to clear program memory upon loading a new program. After the sound card firmware is build, goto file/import and import the hex file for the boot loader. The two projects will be merged together without any cutting and pasting. At this point, it is OK to flash the PIC. Note the bootloader is only necessary for flashing firmwares without a ICD/Pickit. When debugging actual card functionality, it's ok to leave out the bootloader. This Requires no modifications to the sounce or linker scripts. Simply don't merge the boot loader into the image

SOUND CARD FIRMWARE

The sound card firmware is based on a modified version of the Microchip USB framework. The framework has been collapsed into a single source file with callbacks between the framework and the main code. The framework( in my case it’s more of a library ) has been modified to use interrupts instead of the traditional polling method. Instead of calling USBDriverService in a loop, this function is called whenever the USB interrupt fires. The library is response for handling control requests on endpoint 0. The framework handles standard USB requests and the body code is responsible for handling class specific USB requests nonstandard requests. The body code is responsible for handling I/O on all other endpoints.

USB Audio Streamer is a composite device of a USB Audio 1.0 device and a custom HID interface. With USB Audio 1.0 all of the sample data is transferred through a separate endpoint then control requests. Control requests such as controlling volume is through endpoint 0(the control endpoint.) HID uses it’s own endpoint. Since each function of the card has a separate endpoint, each of the functions can be implemented at a different priority level without preemption problems. The PIC18F2550 has two interrupt priorities plus the main handler. This gives a total of three priorities. Since playing sound data is the most critical function it was given the highest priority. Next comes control endpoint requests which include the standard requests plus Audio 1.0 requests. Since these functions have relatively low timeouts, these were assigned low priority. HID functions are in the main body code because actions such as querying the firmware version, settings the serial number, or flashing the firmware are not time critical at all.

Endpoints, priorities, and functions of firmware

CORE AUDIO

The low priority interrupt handler performs two functions. The first is to check the ISO endpoint through the SIE for data. If data is available the buffer is passed to the high priority interupt code and next buffer that makes up a cicular queue is returned to the SIE. The buffers are in the USB ram of the PIC so that the data is not copied between buffers. In Audio 1.0, the host always sends exactly the number of samples to fit in a frame which is 196, 128 or 96 bytes depending on the sample rate used.

The second function of the low priority interrupt handler is SOF(start of frame) processing. Upon receiving the SOF, the PIC changes the current play buffer to the next available buffer and starts timer 2 which is the sample clock. Timer 2 is always reset on the SOF to keep the sample clock synchronized when clock drift is present. If the SOF occurs before the current buffer is played, playback is changed to the next buffer. If the SOF occurs after the buffer is finished, the last sample is stretch. Since the clock drift is normally small, most of the time samples are not dropped. The time of the last sample is slightly different. This is not noticeable in the audio and is only barely noticeable when playing SIN waves.

The high priority interrupt is driven off timer 2 and has the function of formating the data in the format required by the converter and loading the D/A converter through the SPI port of the PIC. The samples are converted from 16 bits signed PCM to 12 bit unsigned and the endianess is swapped. After the buffer is finished, timer 2 is stopped so that if the clock of the card is ahead of the host, the last sample is stretched.

AUDIO 1.0 REQUESTS

All Audio 1.0 requests are handled via an extension of the USB framework. The low priority interrupt calls USBDriverService which services the control request. If the request is a standard USB request, the request is handled by the framework. If it isn't, the framework calls back into the main code which examines the request. If the request is recognized, the main code claims the request. If the request is a read request, the main body sets the address of a variable to sent to the host. If it's a write request, a variable is written to but the firmware sets a completion routine to be called at the end of the request.

The card only handles two types of requests which are volume control and sample rate selection. The current value of both of these is stored in a global variable. If the volume is adjusted, new values are loaded into the variable resistors. If the sampling rate is adjusted, a new period is loaded into PR2 for timer 2.

HID REQUESTS AND HOST SOFTWARE

The main body code polls endpoint 1 for custom requests in a loop. If the request is anything other then setting the serial or flashing the firmware, the request is handled in the main body code. Otherwise, the processor is put into a special programming mode. Upon entering this mode, all interrupts are disabled and the USB library is used in the traditional polling mode as program memory blocks are moved from the host. Flashing the microcontroller is reusable code that is used for multiple projects.

The host side consists of a C++ library that wraps HID and a command line C utility for configuring the card. These utilities are used for multiple projects and will be discussed in a separate topic.

TESTING 123...

The USB Audio Streamer uses instrumentation grade analog components so frequency response is not a major concern. The main concern is noise and signal accuracy due to nonlinear properties of the components, jitter, and that the sample clock can drift from the USB SOF clock.

To measure the accuracy, I used Audicity to play 20 second sin tones of various frequencies and recorded the output on a Dell laptop with a built-in 24bit 96KHz Sigmatel sound card. The assumption is that the 24bit sound card is much better then the USB hardware. The output was recorded with Audicity and the spectrum of the signal plotted. The idea is that perfect hardware would have a single peak at the tone’s frequency and nothing elsewhere. The experiment was performed with both the USB Audio Streamer and a commercial 16 bit USB sound card the Turtle Beach Audio Advantage. In all cases, a 48KHz sample rate was used. In the follow graphs, the Audio Streamer is on the left and the Turtle Beach is on the right.

Cards With Sound

As can be seen, the accuracy of both devices decreases as the tone’s frequency is increased. Up to about 12KHz, both devices have approximately the same noise floor. At 12KHz though, the Audio Streamer’s performance begins to rapidly diminish. Both devices are isosynchronous adaptive, but apparently the Turtle Beach has better drift control algorithms. At 20KHz, even the Turtle Beach has noise of -40dB which is not that good. It seems that designing a high quality USB audio device is very difficult even for commercial developers.

Traktor is DJ software developed by Native Instruments. It is also used as a sub-brand for Native Instruments' associated DJ hardware products.

History[edit]

The first version of Traktor DJ Studio, released in 2001.

Traktor was first released in 2000. The initial versions available were Traktor DJ and Traktor Studio, with Studio being the version with the most functionality.[1]

Version 2 of the software (known as Traktor DJ Studio 2) was released in 2002. The new features included scratch macros and expanded looping, MIDI, and cue point functionality. Version 2.5, released in 2003, expanded the time stretching functionality, added Open Sound Control (OSC) support, and introduced GUI customization options.[1]

In 2003 Native Instruments expanded Traktor from purely software. They partnered with Stanton Magnetics to develop Traktor Final Scratch: the software for Stanton's Final Scratch digital vinyl system (which used timecode-stamped vinyl records to control MP3s), whilst Stanton developed the hardware.[2] This partnership also allowed Native Instruments to use the Final Scratch timecode functionality in their own Traktor products.[1]

In 2005, Native Instruments added vinyl emulation features to version 2.6 of Traktor DJ Studio, alongside live input, internet broadcasting, support for more file formats, and expanded MIDI capabilities.[3]

Version 3 of Traktor DJ Studio, announced in November 2005, added two more playback decks (for a total of four), built-in EQ & effects, Beatport online store integration, a four-channel mixer.[4] It was re-branded to Traktor 3 on October 11, 2006, when the partnership between Native Instruments and Stanton Magnetics ended. At this point, Native Instruments began manufacturing their own DJ hardware components.[5][2]

On October 16, 2008, Native Instruments announced Traktor Pro, to replace Traktor 3. It included an updated GUI, revamped effects interface, and updated cueing and looping features.[6][7]

The subsequent software, Traktor Pro 2 was announced on February 10, 2011, and released on April 1, 2011. New features included multi-channel support and support for a larger number of concurrent loops.[8]

Native Instruments announced in early 2018 that an entirely new version of Traktor (both hardware & software) had been under development.[9] The new version, entitled Traktor Pro 3, was released on October 18, 2018.[10]

Functionality[edit]

Core functionality supported by Traktor includes the following:

4 virtual decks for audio playback[11]

Automatic beat detection and grid-alignment of tracks[12]

Automatic tempo synchronization of tracks, including phase alignment options[12]

Sampling and looping[13]

Effects (such as filter, flanger, and delay)[14]

Waveform displays for visual mixing[13]

Key detection for tracks[15]

A 4-channel mixer (one for each virtual deck) for controlling relative levels and frequencies (via multiple equalizer & filter models[16])[11]

Automatic gain control[17]

Real-time track management with incremental search[18][19]

Artwork browsing[16]

iOS and iTunes synchronization options[20]

Integrated recorder, supporting internal and external audio input[21]

Support for multiple MIDI controllers and mappings[22]

MIDI clock functionality to synchronize external hardware[23]

Support for Ableton Link, to synchronize across multiple devices[24]

Variations of Traktor[edit]

Native Instruments also offers lower-priced version of the Traktor software, known as Traktor Duo. Duo features only 2 virtual decks (compared to the 4 available in the regular version), a single 3-band EQ for each channel, and six effects.[25]

The company have also released Traktor Scratch Pro and Traktor Scratch Duo, which contain the same respective features as their standalone counterparts, along with additional Digital Vinyl System (DVS) functionality, allowing control for timecoded CDs & vinyl.[26][27]

The entry-level version of the software is known as Traktor LE. It is sometimes bundled with third-party DJ controllers.[26]

A version of Traktor is also available for iOSsmartphone & tablet devices. It is known as Traktor DJ.[28]

In August 17, 2010, Native Instruments also released Traktor Pro S4, a new version of the software specialized for their new Traktor Kontrol S4 hardware.[29]

Traktor controllers[edit]

Traktor software can be controlled via hardware MIDI controllers. Native Instruments offers several controllers and mixers designed specifically for control of Traktor software:

TOP 10 OF ANGULAR 10

Angular model 10, has been launched at the twenty fourth of June, 2020 but with the beta version this time. This can imply that we are nearing the final launch of the newest version of the google-developed, typescript primarily based framework. The Version 10.0.0 is a major release that spans the framework, Angular Material, and the CLI. It has only been four months since they launched model 9.0 of Angular. Let’s explore the new features of Angular 10…

Here’s a list of top ten features of the newly updated Angular 10

1. Language Service and Localization

The language-service-precise compiler permits more than one typecheck files by using the venture interface which creates ScriptInfos as necessary. Autocompletion is additionally appeared to have been removed from HTML entities, consisting of &, <, etc., on the way to safeguard the inhouse center functionality of Angular LS, which holds questionable value and a performance cost. One of the fine capabilities of Angular 10 is that the today's angular model supports for merging of more than one translation files which could best load one report in the previous variations. Now clients can specify a couple of documents in step with locale, and the translations from each of these documents may be merged together by a message ID. In practice, this means you want to position the files so as of most vital first, with fallback translations later.

2. Router

The CanLoad shield now can go again Urltree in angular model 10. A CanLoad protect returning Urltree cancels the modern-day navigation and allows to redirect. This suits current conduct to the available CanActivate guards which might be also reputedly added. This however doesn’t have an effect on the preloading. Also, any routes with a CanLoad guard won’t be preloaded, and the guards will now not be completed as part of preloading. 3.Service Workers and Bug Fixes In the previous versions of angular Vary headers might had been considered even as retrieving sources from the cache, however simply stopping the retrieval of cached belongings and fundamental to unpredictable conduct because of inconsistent/buggy implementations in various browsers. However, in angular model 10 Vary headers are omitted even as retrieving sources from the ServiceWorker caches, which can bring about sources being retrieved even when their headers are not similar. If your utility needs to distinguish its responses based totally on request headers, it is important to ensure that the Angular ServiceWorker is configured to keep away from caching the affected sources. With this Angular 10 model, there had been a number of malicious program fixes, this consists of the compiler keeping off undefined expressions in a holey array and the middle averting a migration error at the same time as a nonexistent image is imported. Another worm restore ensures right identification of modules affected by overrides in TestBed. 4. Warnings about CommonJS imports

Starting with version 10, we now warn you while your build pulls in this kind of bundles. If you’ve started seeing these warnings on your dependencies, allow your dependency realize that you’d decide on an ECMAScript module (ESM) package. Converting pre-Ivy code All the pre-Ivy dependencies from npm ought to be converted to Ivy dependencies, which is supposed to take place as a precursor to jogging ngtsc at the application. Further all the destiny compilation and linking operations must be made inside the course of transforming variations of the dependencies.

5.Optional Stricter Settings

Angular version 10 offers a more strict project setup in order to create a new workspace with ng new.ng new --strictOnce this flag is enabled, it initializes the new task with a pair of recent settings that improve maintainability, help in catching bugs well in advance in time, and allow the CLI to perform superior optimizations on your app. Enabling this flag configures the app as side-effect free to make certain extra superior tree-shaking

What the flag does?

Enables strict mode in TypeScript

Turns template type checking to Strict

Default bundle budgets have been reduced by ~75%

Configures linting rules to prevent declarations of type any

Configures your app as side-effect free to enable more advanced tree-shaking

6. New browser configuration

The browser configuration is up to date for new initiatives to exclude older and less used browsers. This has the side effect of disabling ES5 builds by means of default for brand new projects. To permit ES5 builds and differential loading for browsers that require it (which include IE or UC Browser), actually upload the browsers you want to guide within the .browserslistrc file. 7. Typescript 3.9, TSLib 2.9 & TSLint v6

Angular 10 features typescript 3.9. As opposed to the previous version which supported typescript 3.6, 3.7 and even 3.8. Typescript is a language that builds on JavaScript by adding syntax for type declarations and annotations which is used by the TypeScript compiler to type-check our code. This in turn clean readable JavaScript that runs on lots of different runtimes. Typescript helps save the files with its rich editing functionality across editors. With Typescript 3.9 the team has worked on performance, polish, and stability. Apart from error-checking, this version powers things like completions, quick fixes and speeding up the compiler and editing experience.

8.Deprecations

The Angular Package Format no longer includes ESM5 or FESM5 bundles, saving you 119MB of download and install time for Angular packages and libraries. These formats are are not needed as any downleveling to help ES5 is finished at the end of the construct process. Deprecating support for older browsers including IE 9, 10, and Internet Explorer Mobile.

9. Flags and logic

Logic is updated relating formatting day periods that cross midnight, which will fit the time within an afternoon period that extends past midnight. Applications which are the use of either formatDate() or DatePipe or the b and B format codes are likely to be affected by this change. Another point underneath this segment is that any resolver that returns EMPTY will occur to cancel navigation. In order to enable any navigation, builders will should replace the resolvers to update some vale, together with default!Empty. Angular NPM inside the version 10 does no longer contain wonderful jsdoc comments to assist the Closure Compiler’s superior optimizations. Support for Closure Compiler in applications has been experimental and damaged for some times. For folks who will employ Closure Compiler is possibly better off soaking up Angular programs constructed from resources directly in preference to ingesting variations published on NPM. As a brief workaround, customers can't overlook using their present-day construct pipeline with Closure flag --compilation_level=SIMPLE. This flag will make sure that the build pipeline produces buildable, runnable artifacts, at a price of elevated payload size because of advanced optimizations being disabled.

10.New Date Range Picker

Material now consists of a brand new date range picker. To use the new date range picker, you can use the mat-date-range-input and mat-date-range-picker components.

We will be happy to answer your questions on designing, developing, and deploying comprehensive enterprise web, mobile apps and customized software solutions that best fit your organization needs. As a reputed Software Solutions Developer we have expertise in providing dedicated remote and outsourced technical resources for software services at very nominal cost.

d20 Iron Brigade, Post 1 the Basics

Iron Brigade is a DieselPunk Horde shooter released by Double Fine Productions and Microsoft in 2011.   Set in an alternate post World War 1 world where  a mysterious signal swept the world, killing almost everyone that heard it and turning the survivors into technological savants.

The Broadcast

D20rules: When the Broadcast passes through a region of space it can be detected by any suitably powerful radio or television receiver.  Any active radio/television set connected to an “infected” receiver begins broadcasting a loud static noise.  Any creature with an intelligence of 3 or higher that can hear the static must make a DC 27 Fort Save or be instantly slain, any one that passes the save suffers 2d6 points of permanent Strength and Constitution drain.  A creature that survives hearing the Broadcast must then pass a DC 30 Will save, a creature that passes the save gains the technical knowledge necessary to build technologies upto 2 progress levels higher than their world's base progress level.  Creatures that fail the save gains an unbreakable allegiance to the Broadcast and  the ability to create a Monovision network along with all its corresponding creatures and devices.   A creature that fails the will save is also capable of merging itself into a newly created or pre-existing Monovision network.  Once the Monovision network is complete and integrated into society, creatures with an allegiance to the Broadcast will begin attempting to expose all other sapient creatures on their world to it.

Monovision

D20rules: The Monovision network can be used in  a similar way to the internet with successful Computer use and Search checks.  All spells and psionic powers that can be used over a computer network or the internet can be used through the monovision network.

Monovision Network: An inter-connected mesh of “wires”,used to transmit information or Creatures between sets, relays and conduits.  

Monovision sets: resemble a an old-fashioned CRT television set, functions as a high-end Desk top PC.

Monovision Relay hubs: Collect/store data, “houses” the Monovision creatures assigned to its region

Channel the Broadcast:  Farnsworth or a similarly powerful being that has allowed themselves to be completely tied into the Monovision network, can send out less effective versions of the original Broadcast to any Monovision set that is currently turned on and connected to the Network.  All living creatures that can conceivably hear the set are exposed to the Broadcast.

Create Back up (Su): Farnsworth or a similarly powerful being that has allowed themselves to be completely tied into the Monovision network, can expend 5000xp to infuse an animal, monstrous vermin, or magical beast (Int 2 or less only) with cybernetic components created from the Monovision network, this process takes 2d4 weeks and requires the caster or attending assistants to pass two seperate DC 30 craft (mechanical) and two seperate DC 30 first aid checks. If the process is successful, the animal is transformed into a back up unit (see below).  

Conduit

D20rules: Monovision creatures can use the Conduits to enter or Exit the Monovision network with their “Walk the Wires” Special Quality. If creature(s) hostile to the Broadcast approaches within 50ft a conduit, it will release a sonic pulse hurling all un-anchored, creatures or objects backwards 60ft (Ref 25 to resist), creatures thrown back are typically unharmed but, will suffer appropriate falling damage if they encounter a solid object before traveling the full 60ft, anything that passes the reflex save, suffers a -4 circumstance penalty to all saves, checks and rolls until they move more than 50ft away from the conduit.  

Pylons

Pylons are powerful and unique Monovision creatures created to anchor all the hubs and Conduits in a region, Game Masters are encouraged to create their own Pylons to serve as boss enemies.

Scrap

D20rules: When a Monovision creature is slain, it degrades into a pile of “scrap” (typically 1 piece per hit point).  Scrap can be collected by specially designed collection devices and used to deploy and upgrade battlefield equipment.   Scrap not preserved by a Scrap collecting device dissolves after 2d4+1 rounds.

Back-up creature

Back up creature is an acquired template that can be applied to any Medium or large animal, vermin or magical beast with an Intelligence of 2 or lower (from here on referred to as the base creature) by a powerful sentient creature tied into the Monovision network (referred to here after as the creator).  Once created the Creator downloads a copy of their consciousness into the newly created Back-up creature, this copy will remain dormant until the death or destruction of the creator at which point it will activate (referred to as dormant and activated/activation respectively).  A Back up creature does not benefit from any class levels or knowledge that the creator gained after its creation.

Template Creatures

Challenge Rating: Base creature's CR+4 while dormant, Creator's CR+4 when activated

Creature Type: Upon creation the base creature's type changes to Outsider with the Native Subtype

Hit Dice: Upon activation replace the base creature's natural hit dice with the creator's, all die types change to d8

Speed: Becoming a Back up creature does not alter the base creature's speed

Defense: Adds creator's class defense bonus to the base creature upon creation.

Attack/Damage: Replaces the base creature's Base Attack bonus with creator's base attack bonus upon activation

Traits: the new Back up creature gains all traits common to an outsider, The newly created  Back up creature also retains all type and class based special qualities of the base creature, upon activation they gain all the special qualities of the creator.

Mutations (Su):  Upon creation, a Back up creature will develop 1d6-1 mutations (minimum 0)

Cybernetics (Su): During the creation process, the Monovision network extends tendrils that intertwine with the base creature, causing the base creature to “grow” an number of randomly selected cybernetic components equal to the base creature's Constitution modifier.  The Tendrils will also install 1 or more compact monovision screens so the back up creature can properly interact with other sentient creatures but, these do not technically count as cybernetics.

Secondary Back up (Su): Once activated, a Back up creature can create its own Back up creature (using itself as the creator)

Allegiances: At time of creation, the creator's Allegiances replace the base creature's

Saves: While Dormant, a Back up creature retains its base saves.  Once activated, the base creature's Save bonuses are replaced by the creator's base saves

Action Points: Upon activation, the Back up creature gains a number of action points equal to the action points the creator possessed when the dormant backu creature was created.

Reputation: Upon activation, the Back up creature gains the creator's reputation bonus

Ability Scores: A dormant Back up creature retains all the base creature's ability scores, an activated Back up creature replaces the base creature's Intelligence, Wisdom and Charisma scores with the creator's, however the activation process causes 4 points of permanent Wisdom drain

Skills: While dormant, the Back up creature retains the skills of the base creature, upon activation the base creature's skill ranks are replaced by the creator's, however it retains any species based skill bonuses.

Feats: While dormant, a Back up creature retains its base creature's feats, upon activation it gains the creator's feats as well.

Example Back up creature; uses a standard bear (d20modern RPG) as the base creature, and Doctor Roger Prometheus (d20 NPC wiki, based on a character from the old Alternity rpg system) as the creator

SASS always supports all other types of CSS property value such as Unicode range, special character, and unquoted string. 7. Which variable is used to define SASS? A variable begins with a dollar ($) sign, and the assignment of the variable is completed with a semicolon (;) sign. 8. Explain the difference between SCSS and Sass? The main differences between SCSS and Sass are as follow: Sass is like a CSS pre-processor. It has the extension of CSS3. Sass is derived from another preprocessor known as Haml. Sass contains two types of syntax: "SCSS" is the first syntax and it uses the extension of .scss. Indented syntax or "Sass" is the other syntax and it uses the extension of .sass You can covert the valid CSS document into Sass by simply change the extension from .CSS to .SCSS. It is fully CSS compatible. SCSS provides the CSS friendly syntax to closing the gap between Sass and CSS. SCSS is called Sassy CSS. 9. Explain the use of Sass @import function? It facilitates you to extend the CSS import rule. To do this you need to enable import of Sass and SCSS files. It can merge the all the imported files into a single outputted CSS file. It is used to virtually match and mix any file. It needs a filename to import function. It provides document style presentation better than flat CSS. It facilitates you to keep your responsive design project more organized. 10. What are the advantages of Sass? Time saving. More efficient and quicker. Compatible with all versions of CSS. You can use nested syntax and useful functions such as color manipulation, mathematics and other values. Write clean CSS in programming construct It is the super set of the CSS and using nested and others value.

SASS Interview Questions 11. What are nested rules in Sass? Nesting is a method of combining multiple logic structures within one another. In Sass, various CSS rules are connected to one another. For example, if you are using multiple selectors then you can use one selector inside another to create compound selectors. 12. Which one is better, Sass or Less? Due to the following reasons, Sass is better than less: Sass provides the facilities to use logical statements like loops, conditions and also facilitates you to write reusable methods. The user of Sass can access the library of the company. Sass users can also use some awesome features like cross-browser support, legacy browser hacks, and dynamic sprite map generation. Compass also provides the facilities to add an external framework like Bootstrap on top, Blueprint. Sass provides you the facility to write your handy functions 13. What is the way to write a placeholder selector in Sass? In Sass, the placeholder selectors can be used with class or id selector. In standard CSS, these are specified with "#" or ".", but in SASS they are replaced with "%". It uses @extend directive to display the result in CSS. For example: .para1 { color: blue; } .para2 { @extend .para1; font-size:30px; } 14. What are number operations in Sass? In Sass, the number operations are used for mathematical operations like addition, subtraction, multiplication and division. The Sass number operation will do something like take pixel values and convert them to percentages without much hassle. 15. What are the color operations in Sass? In Sass, color operation allows to use color In Sass, color operation allows to use color components along with arithmetic operations. 16. How can we perform Boolean operations in Sass? The Boolean operations can be performed on Sass script by using and, & and not operators. 17. What are parentheses in Sass? Parentheses are used to provide a symbolic logic that affects the order of the operation. It is a pair of signs which are usually marked off by round () brackets or square brackets. 18. Define the use of Sass Mixin function? The Mixin function is used to define styles. Functions and Mixins are very similar. You can re-use this style throughout the style sheet. To re-use it you do not need to resort the non-semantic classes like .float-left. The Mixin can store multiple values or parameters and call a function to avoid writing repetitive codes. It names can use underscores and hyphens interchangeably. 19. What is the use of DRY-ing out a Mixin function in Sass? DDRY-ing out a Mixin function splits into two parts: the static part and dynamic parts. The static Mixin contains the pieces of information that would otherwise get duplicated and the dynamic Mixin is the function that the user going to call. 20. Describe the difference between Sass comment and regular CSS comment? Comments in regular CSS starts with /* */ and Sass contains two commands. The single line comment with // and multiple CSS comments with /* */. 21. Which directive is used to detect the errors in SASS? Sass @debug directive is used to detect the errors and display the Sass Script expressions values to the standard error output stream. For example: $font-sizes: 10px + 20px; $style: ( color: #bdc3c7 ); .container{ @debug $style; @debug $font-sizes; } 22. What are the requirements of SASS system? These are the requirements for Sass system:- Operating System - Cross platform Browser support - Internet Explorer, Google Chrome, Safari, Opera. Programming language - Ruby. 23. What is the use of @extend directive in SASS? The SASS @extend directive is used to share a set of CSS properties from one selector to another. It is a very important and useful feature of Sass. It allows classes to share a set of properties with one another. It makes your code less and facilitates you to rewrite it repeatedly. For example: .message border: 1px solid #ccc padding: 10px color: #333 .success @extend .message border-color: green .error @extend .message border-color: red .warning @extend .message border-color: yellow 24. What is the role of @media directive in SASS? The Sass @media directive is used to set style rules to different media types. It supports and extends the @media rules. This directive can be nested inside the selector SASS but the main impact is displayed to the top level of the style sheet. For example:- h2{ color: violet; } .style{ width: 500px; @media screen and (orientation: portrait){ width:200px; margin-left: 80px; } } 25. What is the use of at-root directive in SASS? The Sass @at-root directive is a collection of nested rules that are used to style block at the root of the document. For example:- h2{ color: blue; background-color: pink; @at-root { .style{ font-size: 20px; font-style: bold; color: violet; } } } SASS Questions and Answers Pdf Download Read the full article

Biomed Grid | Complexity of Hantavirus, its Traits and Treatment

Introduction

Hantavirus is also called as orthohantavirus and are singlestranded, enveloped, negative RNA virus [(-) ss RNA viruses] [1]. It was named after Hantan River area in South Korea where its occurrence was observed and was isolated in 1976 by Karl M. Johnson and Ho-Wang Lee. There are many strains of Hantavirus; normally rodents are the carrier of these virus. Various strains carried by different rodent species are familiar to cause various types of illness in human, most remarkably, Hemorrhagic Fever with Renal Syndrome (HFRS) which was identified during the Korean War – and Hantavirus Pulmonary Syndrome (HPS) which was discovered in 1993 outbreak in the Southwestern United States. Serious HFRS causes acute kidney failure, while HPS gets filling lungs with fluid (edema). Mortality rate of HFRS is 1 to 15 percent while HPS is 38 percent. One of the remarkable outbreaks of Hantavirus in United States was observed of various strains at Yosemite National Park in late 2012 [2,3] (Figure 1-Figure 3).

Template for Drug Design from Structure of Hantavirus Protein

Bank voles are little rodent’s family (Myodes glareolus) that are not fatal by themselves, but their excreta may contain one of the dangerous strains of Hantavirus. However, bank voles are not affected by this virus. In central and northern Europe, contamination is followed by fever, headache or also renal failure [4,5]. The strains of Hantavirus that occurs in East Asia is even more fatal; and up to 5 percent of infected patients die from severe respiratory disorders, hemorrhagic fever or renal failures. Dr. Daniel Olal and Prof. Oliver Daumke from Berlin have evaluated nucleoprotein of Hantavirus by novel method of X-ray crystallography and declassified its three dimensional structure. They have worked on how individual nucleoproteins oligomerize in the existence of RNA molecules and hexameric circular complexes. Nucleoprotein plays a very vital role in replication of viral genome [2]. If its function is disrupted, the cell will be unable to develop functional virus elements. Hence this protein is model target structure for the virus. They also identified three binding pockets on the surface of the protein that can take care of docking sites for such compounds. “This structure could be useful for design of small molecules that particularly block nucleoprotein. Technology for drug development is gets better all the time” was confirmed by Olal [7,8] (Figure 4).

DNA Vaccine and Eggs of Ducks May Defend Against Hantavirus

Army academics with association of other industry collaborators had successfully accomplished in defending laboratory animals from lethal Hantavirus using innovative approach that merges DNA vaccine and duck eggs. As per first author Jay W. Hooper of United States Army Medical Research Institute of Infectious Diseases (USAMRIID), this is the novel method that the DNA vaccine combined with duck egg system has demonstrated to create an antiviral results defending Hantavirus. In this analysis, scientists used a hamster model of Andes virus, which is one of the most vital cause of HPS in South America and Hantavirus was known to be transmitted person to person. Contamination of Syrian hamsters with Andes virus explained the results that disease that closely imitates human HPS in incubation time; syndrome of respiratory, distress and disease pathology. This makes it a prototype system for declassifying the feasibility of post exposure protection strategies. Teaming up with Aldevron of Fargo, N.D. and the Universidad del Desarrollo in Santiago, Chile, Hooper analyzed a natural product, human polyclonal antibody, which was acquired as fresh frozen plasma (FFP) from a patient who sustained HPS.

Their outcome indicates that FFP as a post-exposure preventive remedy for HPS. They also vaccinated ducks with a DNA vaccine against Andes virus. This vaccine uses genetic material or DNA that encodes particular Hantavirus gene to extract an immune response in the receiver. Later they sanitized an antibody called IgY from the yolks of the duck eggs. This sanitized IgY was capable of neutralizing Andes virus when tested in cell culture. Most remarkably, it also shielded Syrian hamsters from deadly HPS even when managed as a single injection survived several days after hamsters had been open to deadly dose of virus. This work indicates the practicability of using DNA vaccine technology coupled with duck egg method. This method could supplement or replace traditional treatment of Hantavirus. Moreover, this new novel method can be scaled as required and eradicated the compulsion of using blood products from HPS sustained patient. “This antivirus production, if fully developed and manufactured; it has the potential to future outbreak situations and it could be used to treat health care employees and others who have close contact with HPS patients” was said by Hooper [9,10].

Cholesterol Performs a Crucial Role in Hantavirus

Viruses mutates very fast, that makes it quickly become more resilient to antiviral drugs. It is noteworthy that viruses also depends on proteins and nutrients supplied by their hosts and hence one of the action plan is to identify new antivirus drugs that can identify and target such host cell components. Proteins that participates in the regulation of cholesterol are very imperative for Hantavirus entry into human host cells. Collaborated with team, Paul Bates and Kenneth Briley from the university of Pennsylvania; identified new pathways in human cells there were very essential for Hantavirus contamination. They concentrated on a member of the Hantavirus group called Andes virus (ANDV), they used less dangerous viruses that were genetically engineered to get results and characteristics with ANDV, and then used ANDV itself to confirm that results were correct for Hantavirus as well.  

 In two independent genetic research, scientists found that four proteins that were participated in Hantavirus contamination and all of them were part of a protein complex that control cholesterol results in mammalian cells. Next they tested an experimental drug that targets one of the four protein could restrict viral entry. They concluded that treating cells that originated from human airways with this drug before revealing them to virus, made the cells less responsive to virus contamination. Because one of the effects of this preliminary drug is that it lowers cholesterol levels in cells. “The sensitivity of ANDV to safe, adequate cholesterol reducing drugs advance new treatments for ANDV contamination and pathogens. Targeting this process may lead to development of effective antivirus” was confirmed by authors [11,12].

Can Statins Used Against Hantavirus?

Researchers at Perlman School of Medicine and Microbiologist might have found novel method to use statins, the well-known blockbuster cholesterol reducing drugs to defend against Hantavirus. The four proteins analyzed by the researchers are the part of protein complex that controls cholesterol. They found that remedying of human airways cells with a generic statin called mevastatin, which reduces cholesterol by a mechanism that does not participate in four proteins. They made the human airway cells less responsive to ANDV contamination. They tested both preliminary drug called PF-429242 and mevastatin and both were competent against Hantavirus. Although, drug inhibition was initially used the engineered virus. Researchers used ANDV itself in high containment Biosafety level (BSL)-3. This research was conducted at University of Pennsylvania School of Medicine [13,14] (Figure 5).

Molecular Signature Decoded of Hantavirus in Humans

Researchers at Charité of Universitätsmedizin Berlin have accomplished in interpreting the molecular signature of Hantavirus that led to an increasing number of outbreaks in Germany. This disease mostly affects kidneys and lungs. In this study shows comparison of the genetic information of a specific viral strain detected in a patient with Hantavirus in Germany. Hantavirus are concealed by specific types of rodents and are transmitted to humans through their excrement. Robert Koch Institute has already registered 2,261 cases of virus in the year 2012. This requires significant research efforts into the illness, its spread and risk of contamination. Through this result of the study, virus break outs and risk of human contamination within Germany can be better defined and understood [15,16].
