He promised he would love me until he died, but his love didn't protect me from his unkindness. He warned me that the Folk don't love as we do. I didn't understand until he left me alone in his great, awful house for weeks on end. I cultivated hybrid roses in the garden and commissioned new curtains and hosted month-long revels for his friends. It didn't matter. I was sometimes louche and sometimes chaste. I gave him everything. But he said all the story had gone out of me. I snapped.

Gender essentialists cower at your TCP art’s feet. They see your She/her gay man Oriana and burst into tears. They pee themselves in fear when they see your butch/femme lesbian Juardan.
Please please please never stop 🙏
Omg I mean very thankfully no one has publicly taken issue with me yet so I've just been having fun in my little corner.
Also it's like... Juardan at least in the books is so aesthetically butch femme I think I'm allowed to mess around with it. There's lots of fey men in the books and though they are said to be beautiful so few of them seem to be rocking with the makeup and skirts and nail polish like Cardan.

How NX-ERA Premium PLCs Revolutionise Textile Singeing Operations

Quality has always held a high priority in the vast and ever-evolving domain of textile manufacturing, as even a single misstep in production can lead to cascading effects, starting from product rejection, leading up to brand loss and compromised customer trust. To ensure a consistent quality in textile finishing, singeing is among the first and most critical steps in the procedure. It is a seemingly sensitive operation where surface fibres are removed using gas flames.
While it may not receive the spotlight like dyeing or printing, singeing lays the foundation for almost everything that follows. It ensures that your fabric output is smooth, clean, and primed for perfection. And in this era of fast fashion, global exports, and digitised factories, managing this process with old-school tools and controls won’t simply suffice.
This is where we at Messung Industrial Automation come in. Our NX-ERA Premium PLCs are a game-changing solution that doesn’t just automate singeing but also redefines how precision, speed, safety, and intelligence come together.
Let’s explore the heart of singeing operations and discover how this Programmable Logic Controller is igniting a silent yet mighty revolution in the textile industry.

Textile Singeing: The First Touch of Refinement
Singeing is a thermal pre-treatment process where the surface fuzz or the protruding fibres on a fabric are burnt off using a controlled gas flame. This eliminates any loose threads or lint that could interfere with the dye penetration or printing clarity.
However, its benefits extend far beyond just aesthetics. They include:
Improved dye absorption and print sharpness
Premium feel through smoother fabric texture
Enhanced garment durability with reduced pilling
Less linting, critical for cleanroom or medical textiles
Compliance with international quality standards, especially in exports
When done right, singeing transforms a raw textile material into a high-value product which is ready for further treatment.
The Complexity Behind
At first glance, singeing might appear as a very straightforward flame treatment, but in practice, it is a process that juggles multiple moving parts with split-second precision. The variables in play are:
Controlling flame intensity and width based on the fabric type and speed.
Tightly monitoring the temperature to avoid scorching
Fabric speed impacts flame exposure time and must be regulated in sync with the burners
Safety systems must be in place to detect flame irregularities, gas leaks, and other emergencies
Include flexibility and minimal downtime for smooth process changeovers.
Due to all these variables, traditional relay-based systems or low-end PLC control systems often fall short, lacking the finesse, feedback loops, or integration capabilities required for modern singeing lines.

The Rise of NX-ERA Premium PLCs by Messung
Recognising the gap between process needs and available automation tools, we at Messung designed NX-ERA Premium PLCs, a high-speed, modular PLC system that is tailored for demanding applications like singeing.
What makes it “Premium”?
The reasons include:

Hydroxyapatite for Bone Regeneration: Clinical Trials and Real-World Applications
Bone defects arising from trauma, disease, or surgical resections present significant challenges in healthcare. Traditional bone grafting methods, while effective, often come with limitations like donor site morbidity and limited availability. This has fueled the search for innovative bone graft substitutes, and among the most promising is hydroxyapatite (HAp), a biomaterial strikingly similar to the natural mineral component of human bone and teeth.
Thanks to its exceptional biocompatibility and osteoconductive properties (its ability to act as a scaffold for new bone growth), hydroxyapatite is at the forefront of regenerative medicine. This article delves into the progress of HAp in bone regeneration, exploring the compelling evidence from clinical trials and its diverse real-world applications.
The Science Behind Hydroxyapatite and Bone Healing
Hydroxyapatite, chemically represented as Ca10(PO4)6(OH)2, is the primary inorganic constituent of natural bone. This inherent similarity is a key factor in its success as a bone regenerative material. When implanted, HAp provides a scaffold that guides osteoblasts (bone-forming cells) and promotes the deposition of new bone tissue. This process, known as osseointegration, is crucial for the long-term stability and success of bone implants.
Beyond its basic composition, advancements in material science have led to various forms of hydroxyapatite, including nano-hydroxyapatite and porous structures. These modifications enhance its surface area, allowing for better cell adhesion, protein adsorption, and ultimately, accelerated bone formation. Researchers are also exploring hydroxyapatite composites, combining HAp with polymers or growth factors to improve mechanical strength and biological activity.
Hydroxyapatite in Clinical Trials: A Growing Body of Evidence
The efficacy of hydroxyapatite for bone regeneration has been rigorously investigated through numerous clinical trials. These studies aim to validate its safety and effectiveness across a range of orthopedic and dental applications.
Orthopedic Applications: Repairing Fractures and Defects
In orthopedics, HAp is being utilized to address complex bone defects resulting from trauma, tumor removal, or degenerative diseases. Clinical trials have shown promising results for:
Spinal Fusion Procedures: HAp-based bone graft substitutes are being explored to promote successful fusion in spinal surgeries. Recent FDA Investigational Device Exemption (IDE) approvals for products like NOVOSIS PUTTY, a dual-carrier system combining HAp and Tri-Calcium Phosphate (TCP) with recombinant human bone morphogenetic protein-2 (rhBMP-2), highlight the ongoing progress and potential for high-density bone formation.
Revision Hip Arthroplasty: Studies have investigated the long-term outcomes of using synthetic hydroxyapatite, often in combination with allograft bone, for impaction grafting in revision hip arthroplasty. Research indicates comparable long-term prosthesis survival and function to using allograft alone, showcasing the potential of synthetic bone graft materials.
Facial Skeletal Reconstruction: Hydroxyapatite implants are proving viable for reconstructing facial fractures and defects, with positive outcomes reported in terms of implant integration, aesthetic results, and patient satisfaction. The development of custom-designed patient-specific HAp implants using advanced manufacturing techniques is further enhancing precision in these complex cases.
Dental Applications: Restoring Oral Health
In dentistry, hydroxyapatite plays a pivotal role in various regenerative procedures aimed at preserving and restoring oral health. Clinical outcomes have demonstrated its effectiveness in:
Periodontal Regeneration: For patients suffering from periodontal disease and subsequent alveolar bone loss, HAp is used as a bone graft material to regenerate lost bone around teeth. Systematic reviews have shown the effectiveness of nanohydroxyapatite grafts in repairing periodontal infrabony lesions, offering comparable results to other bone graft types.
Socket Preservation and Sinus Augmentation: After tooth extraction, HAp bone substitutes are frequently used for socket preservation to maintain bone volume for future implant placement. Similarly, in sinus augmentation procedures, HAp helps build sufficient bone height in the upper jaw for dental implant support. Studies report good bone growth and stable implant integration with HAp-based grafts.
Dental Implant Support: Hydroxyapatite coatings on dental implants enhance osseointegration and promote new bone formation around the implant, leading to improved long-term success rates for dental implants.
Real-World Applications: Transforming Patient Care
Beyond controlled clinical trials, hydroxyapatite has a significant impact in real-world clinical settings, offering viable solutions for a wide array of bone-related conditions. Its ease of handling, biocompatibility, and ability to be tailored into various forms (granules, blocks, putty, coatings) make it a versatile tool for surgeons and dentists.
Synthetic Bone Grafts: The availability of synthetic hydroxyapatite bone graft materials reduces reliance on autogenous (patient's own) bone grafts, which can be limited in quantity and involve additional surgical sites. This is a crucial advantage for both patients and healthcare providers.
Customized Solutions: Advances in 3D printing and bioprinting allow for the creation of patient-specific HAp implants, precisely matching the anatomical requirements of the defect. This level of customization leads to better fit, improved stability, and potentially superior regenerative outcomes.
Combined Therapies: In practice, HAp is often combined with other regenerative materials or growth factors, such as platelet-rich fibrin (PRF) or bone morphogenetic proteins (BMPs), to further enhance bone healing and accelerate tissue regeneration. This multi-modal approach leverages the strengths of different biomaterials.
Challenges and Future Directions in Hydroxyapatite Research
While the evidence for hydroxyapatite's benefits is strong, ongoing research aims to address certain challenges and unlock its full potential.
Mechanical Strength: Pure HAp can sometimes exhibit lower tensile strength and inherent brittleness compared to natural bone. Developing hydroxyapatite composite scaffolds with improved mechanical properties remains a key area of research.
Long-Term Efficacy and Safety: While short-to-medium term results are promising, more extensive long-term clinical studies are needed, particularly for novel HAp formulations and combinations, to fully understand their durability and any potential delayed effects.
Optimizing Resorption Rates: The ideal resorption rate of a bone graft substitute should match the rate of new bone formation. Tailoring the degradation characteristics of HAp materials to specific clinical needs is an active area of investigation.
Bioactive Modifications: Future research will likely focus on incorporating more complex bioactive signals into HAp materials to actively guide cellular behavior and further accelerate the regenerative process, moving beyond simple osteoconduction.
Conclusion
Hydroxyapatite has firmly established itself as a cornerstone in the field of bone regeneration. From its fundamental role as a biocompatible scaffold to its diverse applications in orthopedic and dental surgeries, clinical trials continue to validate its efficacy and safety. As research progresses, with a focus on enhancing mechanical properties, optimizing resorption, and developing advanced composites, hydroxyapatite is set to play an even more transformative role in restoring bone function and improving patient quality of life worldwide. The future of hydroxyapatite bone regeneration looks incredibly promising.
