There are only three original citrus fruits: the citron, the pummelo and the mandarin. All others are hybrids of these three.

Quick Tips: Use of Phytoliths in Archaeology.

Phytoliths are a very important identification tool in identifying plants within ancient environments, often even classifying down to the species of the plant.

But firstly, what are phytoliths? As the name phytolith suggests, coming from the Greekphyto- meaning plants and lith- meaning stone, they are tiny (less than 50µm) siliceous particles which plants produce. These phytoliths are commonly found within sediments, and can last hundreds of years as they are made of inorganic substances that do not decay when the other organic parts of the plant decay. Phytoliths can also be extracted from residue left on many different artefacts such as teeth (within the dental calculus), tools (such as rocks, worked lithics, scrapers, flakes, etc.) and pottery.

Phytoliths can form numerous striking shapes within the plant cells (figure 1), which gives them a characteristic shape, thus aiding the identification of plants. Due to the vast number of shapes and sizes that phytoliths can come in, researchers compiled theInternational Code for Phytolith Nomenclature (ICPN), 2005. The ICPN was developed to create a standard protocol which is to be used during the process of naming and describing a new or known phytolith type, as well as a glossary of descriptors to help aid with the naming.

INFP Characteristics

The INFP, or “Idealist,” is a character that has a very active imagination. They tend to not only see the best in the people around them, but they may also be led to imagining characteristics and motives in others that simply aren’t there. Much like the INFJ, INFPs really dislike conflict and will go to great lengths to avoid an argument and see that everyone is happy. When a conflict does arise, this persona may have a profound emotional reaction. To outsiders, the outburst can see over the top and absurd, but the INFP has a very “internal” thought process in which they struggle to see the logical or factual side of things. They often go by their feelings rather than what science, facts, or logic suggests. Most individuals with this type of personality do not really care if their opinion is right, they simply care about how a situation or a person makes them feel. That is not to say that these individuals cannot be logical – they can, quite successfully, with self-training and abstract thought practices.

Aside from being introverted and internal, “idealists” can be very laid-back and intuitive of those around them. They can get a pretty good sense about a person’s true self (including motives) and are very thoughtful of their findings. INFPs make great listeners and because they are usually non-judgmental they are often sought out by friends who need to vent. This sort of individual may look for hidden meanings in the actions and words of others and may even go so far as to imagine a meaning where none lies. This is simply a result of the dreamer aspect of this personality shining through.

INFPs tend to be perfectionists and often strive to reach personal ideals that can be exhausting or even impossible to obtain. Teamwork is a difficult scenario for this person to be in because they often have higher goals or expectations for the project than the other team members; this can cause an INFP to come off as a control freak. In a relationship, this persona will be looking for inspiration, stimulation, and passion. They feed off of the emotions that others can generation within them. Although this type of individual may have difficulty expression his or her feelings through words, INFPs are great at writing down their feelings. Due to his or her keenly developed imagination, one such as this would likely make an excellent author.

I am unable to describe exactly what is the matter with me; now and then there are horrible fits of anxiety, apparently without cause, or otherwise a feeling of emptiness and fatigue in the head.

I’m sarcastic, skeptical, and sometimes callous because I’m still afraid, deep down, of letting myself be hurt.

Do you ever wait till last second, till you’re alone, and then completely collapse into your bed, to cry your whole scattered soul out. Feeling the small, small, fragile, insecure person you actually are. But then - you have to go, you put yourself together, put your clothes and make - up on and there you go… When you walk in the room, it will always be full of friendly- charm and grounded confidence. And people are drawn to you. That’s how they all see you -nowadays. As this big, charming, lovely personality. Talented, smart, friendly and totally loved. Intimidating. Yes, some are intimated, others are jealous? And it hurts me. What are some people jealous about? If I fought and cried myself into the person I am today. And I’m still crying.

I’m not surprised that you don’t have a boyfriend. I don’t want you to take this the wrong way, I just don’t think that very many people, especially your age, would be able to keep up with you. You know you are and you know what you want to do. Your eyes light up when you talk about your passions, and you’re not afraid to defy social norms and be who you are. And all this, this scares people.

The best compliment I’ve ever received.  (via thatkindofwoman)

INFPs become totally absorbed in projects-- to such a degree that they lose sight of what is taking place around them. They may focus so much on the human element in any situation that they may get off task.

New Tattoos Found on Oetzi the Iceman

New scans have revealed a total of 61 tattoos on the 5,300-year-old mummified body of Ötzi the Iceman, reigniting the debate on whether the inkings were a form of acupuncture that predates the first recorded use of the practice in China by 2,000 years.
