Due to the lack of convincing data about the association between atherosclerosis and osteoporosis, we evaluated the association between carotid atherosclerosis and bone mineral density in a sample of apparently healthy postmenopausal women who underwent health-screening in our hospital. We also evaluated a bone turnover marker, osteocalcin; we divided the population into 2 groups according to o...
Principal component regression (PCR) was used to develop calibration and prediction models for determination of mineral content of complex mineral mixtures by utilizing attenuated total reflectance Fourier transform infrared (ATR-FTIR) spectra. The typical constituents of oil shale such as dawsonite, nahcolite, quartz, dolomite, illite, albite, analcime, and kerogen were used to prepare samples...
Remote sensing has found a special technique and effective in the geological studies and mineral identification for the determination of minerals in the primary detection. The purpose of this study is to recognize the high purity calcite mineral regions in carbonate units using Aster and sentinel 2 images. Sampling of rocks and laboratory analysis using XRF and XRD for verification. The results...
We have applied bioluminescent ATP detection methods to microbial enumeration in Antarctic Dry Valley mineral soils, and validated our ATP data by two independent methods. We have demonstrated that ATP measurement is a valid means of determining microbial biomass in such sites, and that the desiccated surface mineral soils of the Antarctic Dry Valleys contain cell numbers over four orders of ma...
The objective of this study was to compare the use of thermal combustion (CNS) and inductively coupled plasma (ICP) to measure the total S content in plant-, animal-, and mineral-based feedstuffs, and to provide concentrations of other macro- and micro-minerals contained in these feedstuffs. Forty-five feedstuffs (464 total samples) were obtained from suppliers as well as swine feed and pet foo...
background and purpose: multiple sclerosis (ms) is a disease determined by the interaction of genetic and environmental factors. metals are suspected of being involved in ms. there is not any epidemiologic study about mines and ms. the purpose of this study was to determine ms prevalence according to mines in kerman province. methods: this cross-sectional study was conducted on 932 patients in ...
Night-time thermal infrared (NTIR) data provides an additional and potentially valuable source of information for mineral explorers. This technology is used for locating palaeocoastal heavy mineral sands and palaeochannels for uranium and placer deposits. To date, the most frequently used thermal imagery is derived from the National Oceanic and Atmospheric Administration (NOAA) Advanced Very Hi...
در ادراه امور سازمان نیز از تکنولوژی data base در دو زمینه مشخص یعنی بصورت سیستم های عملیاتی و سیستم های اطلاعاتی میتوان استفاده کرد. در شرایط کنونی وجود موانع متعدد از قبیل فرهنگ غالب در سازمان های بزرگ و طرز تلقی مدیران دیوان سالار از یکطرف و تازه گی و پیچیده بودن فنون مربوط به سیتم های data base فقدان دانش، تجربه و تخصص کافی برای بهره گیری کامل از آن از طرف دیگر، برنامه ریزی و اقدام برای ایج...
Mineral analysis of tissue specimens has provided very useful information in pathological conditions associated with occupational exposures to mineral particles, particularly when combined with epidemiological information. Most of the data have been related to exposures to fibrous particles such as asbestos. More investigations of this nature are required in diseases associated with exposure to...
Contaminated mineral oil may have been associated with calcaneous osteomyelitis in a newborn. Staphylococcus aureus is viable for 1 month as a suspension in mineral oil.
