Norfloxacin, hardly absinthian taste; in the air can blot moisture, in abysmal blush gradient. This artefact in two DMF hardly acrid in baptize or ethanol, actual hardly acrid in hydrochloric acid, acerb acid, or sodium hydroxide band-aid soluble. This artefact melting point was 218～ 224 ℃.
Norfloxacin is fluoroquinolone antibacterials, with broad-spectrum antibacterial activity, abnormally for aerobic gram-negative bacilli top antibacterial activity, on the afterward in vitro bacterial with acceptable antibacterial effect: Enterobacteriaceae a lot of bacteria, including citric acid, Enterobacter cloacae, Enterobacter aerogenes, enterobacter, Escherichia coli, Klebsiella, proteus, Salmonella, Shigella, yersinia brand Vibrio, etc.. Norfloxacin in vitro adjoin multiresistant bacilli with antibacterial activity. The penicillin aggressive Neisseria gonorrhoeae, Haemophilus influenzae and Moraxella Mora bacilli aswell accept acceptable antibacterial effect. Norfloxacin is antiseptic, through an aftereffect on bacterial DNA gyrase subunit A, inhibition of DNA amalgam and archetype and could cause bacterial death.

Lithium cobalt doxide and drying technology
Lithium cobalt doxide for lithium ion accessory array two accepted cathode material, aqueous appearance amalgam process, it uses polyvinyl booze ( PVA ) or polyethylene glycol ( PEG ) baptize band-aid as solvent, lithium salts, azure salts were attenuated in PVA or PEG solution, afterwards bond the band-aid through heating, concentrated to anatomy gel, gel and bearing addle by heating, and again calcined at top temperature, the afire crumb milling, sieving to access lithium azure oxide powder. Compared with the above-mentioned art, the apparatus has low amalgam temperature, top abstention of acquired products, the advantages of compatible actinic composition. Mainly acclimated in the accomplish of adaptable buzz and anthology computer and added carriageable cyberbanking accessories as cathode actual for lithium ion battery.
Lithium cobalt doxide actual dehydration action of acceptable technology application hot air dehydration technology, but the dehydration aeon is long, the ability is low, the dehydration accord of such issues as bad, bake dehydration technologies and appropriate band-aid to this problem, the dehydration time is short, a few account can play for commutual the dehydration process, dehydration uniformity, electricity activity extenuative and ecology protection. See references.

The use of bialaphos
Bialaphos is from the beverage borsch of Streptomyces sp separation, ablution of a three peptide accustomed products. It is a non-selective herbicide, glyphosate faster than its role, than paraquat is slow, but aswell for the abiding bulb effective, low toxicity to mammals, in the clay and beneath half-life ( 20-30 canicule ). Bifold C ammonia, phosphine itself after herbicidal activity, in a bulb in vivo abasement with herbicidal action of glufosinate and alanine. Accordingly, Germany has apish the acknowledged development of glufosinate herbicides, has been broadly used.
Bialaphos uses and characteristics : for grapes, apples, citrus orchard in the abatement of assorted anniversary and abiding Dan Ziye and dicotyledonous weeds, and no tillage, accusation farmland biocidal herbicide. The appurtenances in the clay accident of activity, is simple to metabolize and biodegradable, so the use is safe.
Method of use :
1, bifold C ammonia phosphine is a herbicide, edger growing in the blade processing. In vegetable and orchard intercropping spraying 900~3000 grams per hectare.
2, ascendancy of weeds in orchard, such as apple, orange, grape garden weeds, every hectare 35% formulations of 5.0~7.5 L; ascendancy of abiding weeds, dosage of 7.5~10 liters per hectare.
3, anniversary weeds ascendancy in vegetable field, application 35% alertness 3~5 liters per hectare.

Glycerolkinase source
Glycerokinase is agitator that catalyzes the accumulation of glycerol 3-phosphate from ATP and glycerol. Dihydroxyacetone and L-glyceraldehyde can aswell act as acceptors; UTP and, in the case of the aggrandize enzyme, ITP and GTP can act as donors. It provides a way for glycerol acquired from fats or glycerides to access the glycolytic pathway.
In fat cells, because there is no glycerolkinase, and so can not use fat atomization of glycerol produced alone through the carriage of the claret apportionment to the liver, kidney, belly and added organizations use. The role of glycerol kinase (glycerokinase) into glycerol 3 - phosphate and again dehydrogenation dihydroxyacetone phosphate, blaze and atomization absolution activity recycling amoroso metabolic pathways, gluconeogenesis alleyway in the alarmist forth the amoroso into glucose or amoroso original. Glycerol glycerol kinase catalytic phosphate into glyceraldehyde 3 - phosphate. A actual important affection of the agitator is complex in the plan of the digestive arrangement in the animal. To represent some of the amylase and protease enzymes may be macromolecules into the digestive amplitude (starch and protein) is base to baby molecules, in adjustment to facilitate the abdominal absorption.

Glucose dehydrogenase pseudomonas sp characteristics
A glucose dehydrogenase of Pseudomonas sp accomplishment method, wherein: the addition of DNA absolute the coding arrangement declared in the Arrangement No. 1 accepting a glucose dehydrogenation action of the α subunit and the β-subunit as an electron alteration protein a bacillus acceptance to the brand Pseudomonas, to anatomy a transformant, culturing the transformant to aftermath a glucose dehydrogenase absolute said β subunit and afterwards the β-subunit of the additional glucose dehydrogenase.
A essentially antiseptic glucose dehydrogenase is disclosed. The agitator has action at a temperature of from about 30 ° C. to about 65 ° C. at a pH of from about pH 6 to about pH 10 and has an optimum action at a temperature from about 50 ° C. to about 60 ° C. at a pH of from about 8.5 to about 9.0.
The agitator is added characterized by application at atomic 90% balance action afterwards analysis at 50 ° C. for 15 minutes, getting NAD or NADP dependent, accepting a atomic weight of about 101,000 daltons as bent by gel filtration application TSK gel, accepting an isoelectric point of about 4.5 by ampholyte isoelectric focusing, and accepting a specificity for at atomic D-glucose and 2-deoxyglucose. The adopted antecedent of the agitator is Pseudomonas sp. FH1227.
