Q: What is the difference between biodegradation and dissolution of polymers?: Most of the drug carrier materials currently used as controlled release systems are high molecular polymer materials. Biodegradable polymers can be hydrolyzed or digested into small molecules for a certain period of time, can be metabolized from the body through the body, without the need for secondary surgery to remove the carrier material, so more biologically inert materials, more reliable, more reliable, better Biocompatibility, has become the preferred material for drug carriers. The application of the main biodegradable polymers in drug controlled release system is briefly reviewed.

Q: Does the polymer lithium battery have a memory effect?: Lithium battery has no memory effect, you can charge at any time. Of course, with the use of time, battery performance will respond to recession.

Q: Learn what can be done after graduation: Hospital pharmaceutical sales

Q: Skin care products containing what the chemical is not good: Cosmetics originated in the chemical industry, that time from the natural extraction of plants is also difficult, and oil, petrochemical, synthetic industry is well developed. So a lot of skin care cosmetics raw materials from the chemical industry, as of now there are still many international and domestic brands and then use that era of raw materials, a low price, relatively simple raw materials, low cost. So mine, material, oil, the era is the daily chemical era. Cosmetics (including a variety of shampoo, hair dye, skin cream, facial cleanser, nail polish, etc.) are chemical synthetic products, it has both the protection and beautification of the human body function, but also a variety of harmful substances, The skin has a greater stimulating effect, and some can cause skin edema, itching, rash and other "cosmetic dermatitis"

Q: Is the waterproof paint a paint? If not, with the paint class, what is the difference?: Whether it is paint, or wall paint, or has been eliminated by the market what 88 anti-porcelain paint are collectively referred to as paint, but now the paint is generally used for furniture (wood used in paint before also known as paint, now called wood ), Metal surface, due to the requirements of environmental protection, whether it is paint or wall paint to use water to dilute to use, it can also be called water-based paint or water-based paint, is used before the capacity and water, construction can not be dry after the water , Also known as waterproof coating.

Q: Find the additive and multiplicative inverse of -36.?: the additive inverse of -36 is +36 the multiplicative inverse is -1/36

Q: light absorption, which pigments are involved?: All photosynthetic organisms contain one or more organic pigments capable of absorbing visible radiation, which will initiate the photochemical reactions of photosynthesis. The three major classes of pigments found in plants and algae are the chlorophylls, the carotenoids and the phycobilins. Carotenoids and phycobilins are called accessory pigments since the quanta (packets of light) absorbed by these pigments can be transferred to chlorophyll. Chlorophylls chlorophyll a - present in all higher plants and algae chlorophyll b - present in all higher plants and green algae chlorophyll c - diatoms and brown algae chlorophyll d - red algae (chlorophyll a is present in all photosynthetic organisms that evolve O2.) Chlorophyll molecules contain a porphyrin 'head' and a phytol 'tail'. The polar (water-soluble) head is made up of a tetrapyrrole ring and a magnesium ion complexed with the nitrogen atoms of the ring. The phytol tail extends into the lipid layer of the thylakoid membrane. Carotenoids (carotenes and xanthophylls) Carotenes: -carotene - higher plants and most algae $-carotene - most plants some algae xanthophylls: luteol, fucoxanthol and violaxanthol Carotenoids contain a conjugated double bond system of the polyene type (C-C=C-C=C). Energy absorbed by carotenoids may be transferred to chlorophyll a for photosynthesis. Phycobilins (found mostly in red and blur-green algae): phycoerythrin phycocyanin allophycocyanin )

Q: Spring to the mulberry began to mature, this sweet and sour feeling really good. What are the benefits of eating mulberry on our body?: Beauty! Anti-cancer ah, the stomach with laxative effect, mulberry I also like to eat! I also like to eat the largest and sweetest black car centimeters, eat fruit can not eat broken fruit! All broken fruit is the same as bad fruit! Are there any praise?

Q: a number whose additive inverse and multiplicative inverse are same in modular arithmetic?: If a mod m has a multiplicative inverse, a^-1 then aa^-1 1 mod m a is relatively prime to m. Clearly the additive inverse of a mod m -a mod m. If -a a^-1 mod m then -a^2 aa^-1 1 mod m a^2 -1 mod m. -1 is a quadratic residue mod m. If for example m a prime number p then a^2 -1 mod p (-1)^{(p-1)/2} (a^2)^{(p-1)/2} a^(p-1) 1 mod m (this last is by Fermat's little theorem). Then (-1)^{(p-1)/2} 1 (p-1)/2 is even p 1 mod 4. On the other hand if p 1 mod 4, then let a 2*3*.*{(p-1)/2}, and b (p-2)*.*{p - (p-1)/2}. Then the inverse of any factor i in a is contained in either a or b, and the inverse of any factor j in b is contained in a or b ab 1 mod p. But (p-1)*(p-3).*(p-(p-1)/2) (-1)*(-2)*.*(-(p-1)/2) mod p (-1)^{(p-3)/2}a mod p -a mod p -a^2 1 mod p a^2 -1 mod p. So x^2 -1 mod p is always solvable if and only if p 1 mod 4 when p is prime. From then on you see that x^2 -1 mod p^n is always solvable using taylor series (Hensel's Lemma). Using the Chinese remainder theorem if m p(1)^e(1).p(r)^e(r) and p(i) 1 mod 4 for all i then the equation x^2 -1 mod m is always solvable. As an example let m 13, then 5^2 25 -1 mod 13, and 5^-1 8 mod 13, since 5*8 40 1 mod 13, and -5 mod 13 8 mod 13. So 5^-1 - 5 mod 13.
