1. A: the fact of ocean world blockchain should be reliable.

2. The 1809 fund has now revised its rules to charge fish and grain at one time, starting point-to-point in March

Water sprite is a kind of water absorbent resin, the proction of water sprite needs starch mixed with acrylonitrile or acrylate, and acrylonitrile and acrylate have certain toxicity, can not be made by indivials

water spirit main components:

acrylonitrile: acrylonitrile, CH2 = CHCN, is a colorless, flammable and volatile liquid, with a special almond smell. It is slightly soluble in water, and its low concentration aqueous solution is very unstable and easily soluble in general solvents

acrylic acid was formed ring hydrolysis and propionitrile was formed ring rection. It is easy to polymerize and can also copolymerize with vinyl acetate, vinyl chloride and other monomers. In instry, acrylonitrile is mainly used in the manufacture of acrylic fiber, NBR, ABS engineering plastics, acrylate and acrylic resin

acrylonitrile is highly toxic and can cause acute and chronic poisoning after entering human body

the clinical symptoms of acute poisoning caused by acrylonitrile: the symptoms of mild poisoning were fatigue, dizziness, headache, nausea and vomiting, accompanied by mucosal irritation

In addition to the above symptoms, chest tightness, palpitation, restlessness, dyspnea, cyanosis, convulsion and coma may occur in severe poisoning. If not rescued in time, respiratory arrest may occur

the chronic toxicity of acrylonitrile to human body has not been determined yet, which is generally manifested as neurasthenia syndrome, such as dizziness, headache, fatigue, insomnia, dreaminess, irritability, etc

In addition, acrylonitrile can cause contact dermatitis, such as erythema, herpes and desquamation

The gelatin was soaked in tap water, then the liquid was poured into the mold, and then the whole mold was soaked in the liquid of calcium chloride

After cooling, the water spirit is born. In fact, edible gelatin is the raw material for making jelly, and it can also be replaced by an additive called sodium alginate, so the feeling of touching water elves with hands is like jelly. And the so-called "egg" is made according to this method

it is understood that if instrial raw materials are used in the processing of "water spirit", it will be harmful to health“ The proction of "water spirit" is very simple“ Don't play with "water elf" toys because they are poisonous

< H2 > extended information:

the defective proct management center of AQSIQ specially issued the consumption warning of water spirit

it is learned that water spirit is a kind of water absorbent resin, which is similar to the shape and size of marbles, and has strong water absorption and elasticity when meeting with water. Claiming to be a "water spirit" of marine organisms, it is actually a poisonous resin. Parents should keep their children away from such procts, so as not to bring disastrous consequences if they eat them by mistake

the reporter picked up a bag of "water spirit" and found that there was no manufacturer and label on the package, which was a typical "three no" commodity. When asked if the vendor knew it was toxic and had hidden dangers, the other side said it didn't know

Chief Physician Wen Wenli, director of internal medicine of Wuhan children's Hospital, said: once the human body eats "water spirit" by mistake, it will absorb water and swell in the stomach because it can't digest. If the "water spirit" is eaten by children, it is easy to block the respiratory tract, which is very dangerous. Once swallowed by mistake, it can only be removed surgically< br />

4. The maximum supported memory frequency of 1230 V3 CPU is DDR3 1600
the maximum supported memory frequency of Z87 motherboard is DDR3 2800

if you are sure that you can only get up to 1600 on V3, you can't use it if it is too high.

5. In fact, he is different from the earth. The earth has enough oxygen. However, although there is no oxygen on the earth, there is advanced civilization

Mineral water is filtered

the mechanical filter mainly uses quartz sand as the basic filter material to remove the sediment, manganese, rust and other impurities with large particle size in the water. Generally, activated carbon is used as a filter to rece the hardness of water and remove the chlorine content and other substances that may be harmful to human body

under the external pressure, colloids, particles and relatively high molecular weight substances in water were intercepted, while water and small solute particles were separated through the membrane

extended data:

mineral water generally should not be heated cold drink or slightly heated, preferably not boiled

Mineral water generally contains more calcium and magnesium and has a certain hardness. When boiling, calcium and magnesium are easy to precipitate, which is what we often call scale. In this way, calcium and magnesium are lost, and sensory discomfort is also caused. Therefore, the best way to drink mineral water is to drink it directly at room temperature

drinking mineral water reasonably is very important. Pregnant women should drink more mineral water. The trace elements in mineral water are helpful to the development of fetus and maternal health. The best amount of mineral water is 2 liters per day; Baby milk with mineral water, not only can enhance appetite, increase nutrients, but also is safe and clean

7. Overclocking performance is improved by at least 20%. Multithreading is not helpful in playing games, and the performance gap of K-band overclocking is obvious

I haven't used 4770k, only 3770k OC 4.3G. It's stable all year round. The toaster is 80 degrees. It uses Antaike water cooling, power supply and memory. The temperature is very high and needs auxiliary cooling
in addition, watch your motherboard before changing it!!!! Must be high-end Z87, otherwise the power supply is not good is not super up. At least we need to consider the level of Z87 pro, 1500 yuan
when I say that the frequency can't be exceeded, I mean that if you adjust the frequency doubling and overclocking directly, you don't have to say that B85 can overclock... Moreover, if the power supply is not good, the motherboard needs + voltage, the temperature is higher, and the 100 degree frequency will fall down, which is very unstable. It's very bad for CPU and motherboard
consider the heat dissipation by yourself. As my friends said later, the more expensive the radiator is, the better. My cheap one is only 500, and the memory should have its own heat sink. The calorific value of two 770 can't be underestimated. Prepare the fan of the whole case

there are few default voltage overclocking systems. The first batch of procts are OK, but the later ones are not. In a word, the mainboard is large in terms of money.

Intel Xeon e3-1230 V3 adopts the new Haswell core architecture. It belongs to the E3 series of Xeon processor, server level processor. And I series belong to different series

{rrrrrrr}

basic parameters

number of cores: four cores
proction process: 22
main frequency: 3.3GHz

extended materials

advantages:

low temperature, low power consumption, i5 price, i7 performance, in addition to no core display and the same generation of i7 without K, there is no difference, I locked 39 pieces of 3.8 frequency fan, the temperature is about 30, aida64 single fpu70, if not locking 20 yuan fan enough

disadvantages:

no core display, can't over frequency, The obsessive-compulsive patients feel uncomfortable.

conclusion:

the price performance ratio is very high. E3 + B85 + 20 yuan fan heat and i7 without K + Z97 + 100 yuan fan heat are about 1000 cheaper than the price, and the performance is almost the same.

10. For the first immunization of puppies, three injections of vaccine are required, and the price is generally about 80-120 per shot. Some group buying platforms have packages that will be relatively preferential. For one shot of rabies vaccine, there is a general charge for imported vaccine. You can also make an appointment with a pet hospital to get free domestic vaccine. Vaccination needs to go to a regular pet hospital. After immunization, the vaccine will be given to facilitate the dog certificate or immune quarantine certificate in the future
you don't need to bring a dog certificate to a pet hospital.
