The levels of formaldehyde (FA) and acetaldehyde (AA) in polyethylene terephthalate (PET) bottles and in commercial mineral water are reported. All the water samples bottled in Japan contained detectable levels of FA (10.1-27.9 microg l(-1)) and AA (44.3-107.8 microg l(-1)). Of 11 European bottled water samples, eight did not contain either FA or AA, while the remaining three had detectable lev...

The purpose of this investigation is to characterize nevirapine from commercial samples and samples crystallized from different solvents under various conditions. The solid-state behavior of nevirapine samples was investigated using a variety of complementary techniques such as microscopy (optical, polarized, hot stage microscopy), differential scanning calorimeter, thermogravimetric analysis, ...

in this research, seeds of iranian carob trees grown wild in kazeroon city (fars province) were used to extract iranian locust bean gum as a seed galactomannan. chemical composition, solubility, and rheological properties of crude and purified gums were investigated and compared with a commercial (sigma) locust bean gum (lbg) sample. chemical composition of the purified iranian lbg was similar ...

In this study we estimate technical efficiency of Indian commercial banks from 19892009 using a multiple-output generalized stochastic production frontier, and analyze the effects of financial sector reforms on measured efficiency. This generalized technique estimates technical efficiency in the presence of multiple outputs, filling a gap in the existing literature. Our results show that Indian...

This study was developed and validated for the determination of oxyclozanide residue concentrations in beef and commercial milk, using high-performance liquid chromatography system. Oxyclozanide was successfully separated on a reverse phase column (Xbridge-C(18), 4.6×250 mm, 5 µm) with a mobile phase composed of acetonitrile and 0.1% phosphoric acid (60:40, v/v%). This analytical procedure invo...

purpose: the main purpose of this study was to identify the type and the extent of hurtful elements in commercial picture storybooks which have been published in iran for the children grades of a and b. these elements were categorized into two groups: i.e., carelessness in specifying book features, such as the title page, the information page, etc. and other elements (i.e., attractive features,...

This paper describes the experience and the results of using the VigilAgent agent methodology to develop surveillance systems. This work is based on the suitability of agent characteristics for developing surveillance systems. It is usual to develop them following an ad-hoc approach instead of using a methodology to guide stakeholders in achieving quality standards expected from commercial soft...

Department of Chemistry, Avinashilingam Deemed University for Women, Coimbatore641 043 ABSTRACT Lipophilicity which plays an important role in research into the structure-activity relationship of drug action has been theoretically predicted for few chromen-2-ones and chromen-2-thiones using commercial software HyperChem 7.0 and an internet computational software ALOGPS 2.1. In the compounds ana...

Background: Bradford protein assay is popular due to its ease of performance and relative sensitivity. Many researchers and laboratories in Iran use standard assay of Bradford by cuvette. No commercial kit was available for Bradford microplate assay in Iran. Meanwhile, imported Bradford commercial kits are very expensive and have a long delivery time in Iran. Till now no study or document on Br...
