Library classification is one of important tasks in any library. Classifying books is as the art of assigning books to their proper places in a system of classification in which the various subjects of human inquiry, or the descriptions of human life in its various aspects, are grouped according to their likeness or relation to one another (Merrill, 1939). In order to conduct these tasks, using one of library classification schemes is one basic requirement. Dewey Decimal Classification is one of them which help the librarians to do that.

The usage of cloud computing environment is increasingly common and we rely on it for various services. Cloud services means services made available to users on demand via the Internet from a cloud computing provider's servers as opposed to being provided from a company's own on-premises servers. Cloud services are designed to provide easy, scalable access to applications, resources and services, and are fully managed by a cloud services provider.

Due to recent development of artificial intelligence (AI) applications in active power filter (APF) growth of electricity market has distinguish in the intelligence users recognize electricity. These changes may require consumers have become more challenging. The amount and feature of the data being confined in existing electrical power monitors through artificial intelligence (AI) has been increasing significantly in recent years.

Thick films of pure and Cr2O3 doped ZnO with various concentrations (1 wt. %, 3 wt. %, 5 wt. %,7 wt% and 10 wt% ) of Cr2O3 were prepared on alumina substrates using a screen printing technique. These films were fired at a temperature of 700ºC for two hours in an air atmosphere. Morphological, compositional and structural properties of the samples were studied using the scanning electron microscopy (SEM) and X-ray diffraction techniques respectively. Crystallite size, lattice parameters and specific surface area of undoped and doped films were determined.

The known integrable models possess Schwarzian forms with M¨obious transformation invariance, it may be one of the best ways to find new inte grable models starting from some suitable Schwarzian forms. In this paper, with introducing the high dimensional Schwarzian derivatives, the general (n + 1)-dimensional systems are obtained from the usual (1+1)-dimensional Schwartzian Boussinesq equation. A singularity structure analysis of the extension system is carried out and it is shown that arbitrary dimensional systems admit the Painlev´e property.

A quantitative method of Cr (VI) - determination by using diphenylcarbazid reagent was studied in detail. This method exhibits a very high sensitivity in analyzing Cr(VI) in water samples. The optimal condition for the determination of Cr (VI) was established. If in the samples, the much excess of Cr (VI) compared with DPC the maximum absorbance of color complex would be reduced. This is very important problem when use of the method in practice.

The median lethal concentration (LC50/96h) of Chromium Chloride for the estuarine clam, Mactra violacea was recorded to be 2.4 mg/l.  Acute chromium exposure (0.24 mg/l = 1/10th of LC50/96h) to M. violacea caused histological alterations in the chief metabolic organ namely digestive gland.  Histological studies showed that the digestive gland tissues suffered more on 72h and 96h exposures than 24h and 48h exposures.  Distinct histomorphological alterations namely epithelial degeneration, necrosis, vacuolation and granular cytoplasm were noticed in acute treated digestive diverticula of M.

Acid lime (Citrus aurantifolia) is grown different agro-climatic situation in West Bengal. The crop is commonly affected by citrus canker caused by Xanthomonas axonopdis pv. citri. There was variation in severity of the disease in different orchards. Xanthomonas axonopodis pv. citri isolated from five different orchard showed variation in respect to virulence and enzymatic activity. Isolates of the pathogen were XacJP from Jagannathpur, Paschim Medinipur, XacJ from Jaguli, Nadia, XacK from Kalyani, Nadia, XacMON from Mondouri, Nadia, XacMHP from Mohanpur, Nadia.

Rice is a major component of the agricultural sector in particular and the overall economy in general. Rice is one of the most important staple food for more than half of the world’s population and influences the livelihood and economies of several billion people. Paddy loss due to flooding in Bangladesh and India alone amounts to an estimated 4.0 million tons per year enough to feed 30 million people. Over 20% of rice land in Bangladesh is prone to floods which occur every year (IRRI 2010). Such produce is often sold at low price causing economical loss to the farmers.

This paper presents the results of studies on the ability to handle cyanide in metal plating wastewater in the Thanh Thuy village of Thanh Oai district, Hanoi city. The results showed that water hyacinth plants are capable of well growing in the water of pH from 6.00 to 7.00. This plant can be applied for treat cyanide in metal plating wastewater with the concentration about 0.190 mg/L. The water hyacinth with the 2days of age can be applied in treating cyanide with the highest efficiency, reached 89.4 %.
