aConstruction or extensions of new hotels in east Jerusalem are restricted because the Israeli does not allow such actions, although, these restrictions do not exist in West Jerusalem. 新的旅馆建筑或引伸在东部耶路撒冷是限于,因为以色列人不允许这样行动,虽然,这些制约不存在于西部耶路撒冷。[translate] ...
Why is deuterium used in NMR? Why don't crystalline polymers have a glass transition temperature? Why do liquids flow and solids do not? Why does it matter how glass transition temperature is determined? Why doesn't deuterium have an excited state?
Question: Briefly explain why different nuclei (hydrogens) in a molecule give rise to their own NMR signal. Nuclei: The group of particles that is present inside the nucleus of an atom is known as the nuclei. Nuclei are a combination of both protons and neutrons. NMR...
What does this mean for applications of AI in drug discovery? AI can, in principle, deliver all of the above aims: it can make decisions faster (predictions are faster than experiments) and more cheaply (predictions cost less than experiments), and lead to better decisions (where suitable dat...
It clearly does not make it right. There is an overpopulation of animals being bred on factory farms and it’s destroying the environment, hindering the long-term survival of every single living being on this earth, but you’re right.. that’s another subject. _”Btw I know some vegans,...
LDL-P is measured by a so-called NMR lipid profile test. A value of less than 1.000 is considered ideal. Above 2.000 is considered very high. Ideal: <1000 Moderate: 1000-1299 Borderline High: 1300-1599 High: >1600 How to Lower LDL-P Much has been written about how to lower LDL-C....
Proteins are polymers, and yet the language used in describing their thermodynamics and kinetics is most often that of small molecules. Using the terminology and mathematical descriptions of small molecules impedes understanding why proteins have evolved to be big in comparison. Many properties of the...
Does an aldehyde have a carbonyl group as a part of its structure? Explain. Why is the para carbon in Benzaldehyde NMR more deshelled than the ortho and meta carbons? Explain why the following organic compound cannot exist. 2-pentanal ...
Why does the earth's atmosphere contain only small amounts of carbon dioxide? Why is a salt bridge necessary in galvanic cells? Explain why the cyclopentadienide anion A gives only one signal in its ^{13}C NMR spectrum. Why are buffer systems important in living organisms?
When you have an ice cube and at some point, it melts and becomes water, then it is said to have reached the melting point. To define, the melting point is the temperature at which a pure substance's solid and liquid forms exist in equilibrium. It has the same temperature when a soli...
