AbstractObjectives: This study was conducted to compare the subjective sleep quality of a group of chemical warfare veterans and a sample of healthy controls. Method: Pittsburgh Sleep Quality Index (PSQI) was used to assess the sleep quality of 78 chemical warfare veterans as well as 65 controls. Results: 73 subjects (93%) in the case group and 39 subjects (60%) in the control group were poor ...
The objective of current study was to investigate the effects of whey protein coating on the quality of common kilka during frozen storage period. For this study, common kilka was coated with 12% whey protein concentration. Also, non- coated kilka was used as a control sample. Coated and non-coated samples were then stored at -18 oC for six months. Bacterial, chemical and sensory properties of ...
The current study aims to investigate the community structure of macrobenthos to evaluate water quality of Jajrood River, Northeast Tehran, Iran. We conducted this study in 12 stations during the Spring and Winter seasons of 2014-2015. The sampling method of macrobenthos is use of the surber sampler device with three replications in each station. We measured physical and chemical parameters in ...
tacrine (9-amino-1,2,3,4-tetrahydroacridine) as a reversible inhibitor of acetylcholinesterase (ache),was the first drug for the symptomatic treatment of alzheimer’s disease (ad). nmr structuredetermination still presents some considerable challenges: the method is limited to systems ofrelatively small molecular mass, data collection times are long, data analysis remains a lengthyprocedure, and...
We participated two chemical information retrieval tasks, Technology Survey (TS) task and Prior Art (PA) task in TREC 2010 chemical track. We aim to discover extra relevant chemical compounds for a given query. We investigate various basic retrieval models as well as corresponding Pseudo Relevance Feedback(PRF) models in chemical experiments. In order to eliminate low quality feedback documents...
The aim of this study was to do a preliminary assessment of the chemical and microbial surface water quality of the Chunies River. For this purpose sampling was undertaken on 25 and 26 May 2002, and a range of chemical (macro-elements, micro-elements and heavy metals) and microbial variables (HPC, total coliforms and faecal coliforms) were measured. The chemical water quality of the second sect...
Objective: Button mushrooms (Agaricus Bisporus) are among the most widely produced and consumed mushrooms in the world. Generally speaking, mushrooms are of great nutritional value, which due to their high content of moisture and their corruptibility particular attention is required to be paid to their conservation and health. Drying is one of the most important ways to preserve the yi...
nowadays nmr spectroscopy becomes a powerful tool in chemistry because of the nmr chemical shifts. hartree–fock theory and the gauge-including atomic orbital (giao) methods are used in the calculation of 29si nmr chemical shifts of various silicate species in the silicate solution as initial components for zeolite synthesis both in gas and solution phase. calculations have been performed at geo...
Rapid development and population growth have resulted in an ever-increasing level of water pollution in Malaysia. Therefore, this study was conducted to assess water quality of Selangor River in Malaysia. The data collected under the river water quality monitoring program by the Department of environment from 2005 to 2015 were used for statistical analyses. The local water quality indices were ...
Management systems influence soil quality over time. A randomized block design in 2 (tillage system) 3 (crop rotation) factorial arrangement was laid-out to evaluate the impact of tillage and crop rotation (2002–2007) on soil quality. Conventional tillage and No-till were factored into continuous corn, corn–soybean, and corn–soybean–wheat–Cowpea systems. Ten soil cores were collected at 0–7.5, ...
