Shortwave infrared (SWIR) spectroscopy can be applied directly to analyze the mineral chemistry of raw or geologic materials. It provides diagnostic spectral characteristics of the chemical composition of minerals, information that is invaluable for the identification and quality control of such materials. The present study aims to investigate the potential of SWIR spectroscopy as an alternativ...

The purpose of this work was to improve the quality of jack pine TMP long fibers, particularly with respect to the strength properties, by alkaline peroxide treatment. This paper reports the chemical characteristics of the treated long fibers and the spent liquors originating from various treatments. It was observed that, in comparison with hydrogen peroxide, the alkalinity of the treatment sol...

T HIS iS .A very interesting book. It is divided into two main sections one on the tubercle bacillus and one on laborator-y methods. The section on the tubercle bacillus gives a most interesting and comprehensive survey of the great amount of wvork that has been done on the characteristics of the organism-its mo)rphology, the cultural characteristics of its various types, its pathogenicity for ...

douala metropolitan city loated in the littoral province of cameroon,has experienced a rapid urbaniation and industralisation. the city depends heavily on groundwater as a resource. due to ubiquitous sources of pollution, groundwater quality and contamination has become an imprtant issue for this urban groundwater supply. this study uses the major ion chemistry of groundwater together with t...

1 In recent years school readiness has become a primary goal for the majority of Pre-Kindergarten programs in the United States. A lack of readiness is thought to lead to difficulties throughout a child’s life in the academic world (Rouse, Brooks-Gunn, & McLanahan, 2005, pg. 6). Most readiness discussion has focused on the skills the children need to be “ready.” But, ready for what? School read...

this review focuses on the introduction of par-baked bread technology and effects of map on the microbial and sensorial shelf life of the mentioned bread, which are discussed here under four categories of the product contamination after probating, the composition of the gas, the characteristics of the packaging material, and the packaging technology. since traditional breads have a low quality ...

A pulsed metal-organic chemical vapor deposition technique is developed for the growth of high-quality AlN/GaN superlattices SLs with intersubband ISB transitions at optical communications wavelengths. Tunability of the AlN and GaN layers is demonstrated. Indium is shown to improve SL surface and structural quality. Capping thickness is shown to be crucial for ISB transition characteristics. Ef...

sludge drying bed is preferred to mechanical methods due to the need for very simple technology. due to restriction of natural dewatering, we tried to eliminate some of these limitations by the tests and studies of assumptions. in this study, the effect of hydrostatic suction and sludge chemical conditioning has been studied in the natural sludge dewatering optimization. at first, hydrostatic s...
