Abstract:
A simplified determination procedure for alanycarb in agricultural products by high performance liquid chromatography with a UV detector was developed.The homogenate of agricultural products was extracted with acetone. The crude extract was partitioned between 10% sodium chloride solution and ethyl acetate, and the ethyl acetate layer was evaporated to dryness. The residue was dissolved in n-hexane, and the solution was cleaned up on a Bond Elute® extraction cartridge PSA, then analyzed by liquid chromatography. Alanycarb was detected by measuring the absorbance at 230nm.Recoveries at the 0. 1ppm level were more than 70% from agricultural products except brown rice. Detection limits for the products were 0.01ppm in samples.Keywords:

Feature and development of cartridge valve are introduced, also the application of cartridge valve in industrial field of China. Analyze a case of using cartridge valve group to control the differential cylinder, by analyzing the problem and solution indicate the factors which should be pay attention to in using the cartridge valve.

The Accelerator® cartridge is unique in that the bullet has no barrel markings after it is fired. The plastic sabot does have barrel markings and can produce distinctive wound patterns. The .30-′06 Accelerator cartridge was fired into poster board, gelatin blocks, and pigs. The results of these studies are presented.

This study aims to determine the effect of Cassia alata L. ethyl acetate and n-hexane leaves extract in inhibiting the growth of Candida albicans. The study used an experimental laboratory. In this study, C. alata ethyl acetate and n-hexane leaves extract used with concentrations of 2% w/v, 4% w/v and 8% w/v. The results showed that ethyl acetate and n-Hexane extracts inhibit C. albicans growth at 2% w/v, 4% w/v and 8% w/v concentrations with diameters of 9 mm, 11 mm, 13 mm for ethyl acetate and 9.3 mm, 12 mm, 14 mm for n-hexane solvent.

A nozzle plate cartridge for the extraction section and a mixed plate cartridge containing both stainless steel and fluorothene sieve plates for the scrub section were developed. In 3- and 4-in.-diameter glass columns, these cartridges have a urnnium-extraction efficiency as good as, or better than, the present cartridge; they have a scrubbing efficiency, based on the transfer of chloride ion, which is about the same as the present cartridge.

Aluminum cartridge case has long been considered as the alternative material for brass cartridge. It can efficiently reduce the weight carried by soldiers, help soldiers carry more ammunition with the same cartridge case, and thus improve the combat effectiveness. However, Aluminum cartridge case can be broken off during the course of use, which is a common phenomenon. By using the finite-element method, the paper is intended to analyze the effects on the deformation of cartridge case, the position and magnitude of maximum strain with the headspace variation law ;the maximum headspace of aluminum cartridge; the simulation result that maximum headspace indeed causes break is also verified by the firing experiment.

In order to improve cartridge valve response speed,Working principle of cartridge valve is introduced,and the model of cartridge valve is simulated by AMESim software,drawing conclusions to improve cartridge valve response speed.The results show that stroke of main cartridge valve and the damping between main cartridge calve and pilot-operated valve effect hard to dynamic properties of cartridge valve;and closure time of main cartridge valve has been shorten from 0.341 s to 0.087 s,the effect of optimization is evidential,and have some guidance to improve response speed of cartridge valve.
