Introduction Iron ore is one of the most important natural raw materials that is widely used for manufacturing iron and steel. This type of ore contains various amounts of radionuclides; thus, exposing workers handling their extraction, transportation, and processing to radiation. Materials and Methods In this study, 12 ore samples (each mass weighing about 2 kg) were collected from the iron or...

Background: Medicinal plants use is growing in Iran and controlling their quality in terms of contamination with toxic metals is critical. City of Arak, due to its large industrial plants, is one of the most polluted cities of Iran these pollutants can be transferred to the farms. Methods: In this study, concentrations of metals such as aluminum, arsenic, lead and cadmium are measured by atomic...

conclusions the levels of resistance to ceftazidime were remarkably variable among ctx-mproducers. this study provides further evidences of the global dissemination of ctx-m type esbls and emphasized on the need for their epidemiological monitoring. results in phenotypic confirmatory test, 154 (44%) out of 350 clinical isolates were esbl positive. using molecular assay, 154 strains potentially ...

BACKGROUND The objective of this study was to investigate HLA-DRB1*and DQB1* allelic polymorphisms in Iranian patients with hydatidose. This is the first survey dealing with the correlation between HLA-DRB1* and DQB1* alleles and cystic echinococcosis in Iranian patients. METHODS The study was carried out on 56 patients with confirmed cystic echinococcosis and 30 apparently healthy individual...

The purpose of this paper is to construct perfect samplers for length-interacting Arak–Clifford–Surgailis polygonal Markov fields in the plane with nodes of order 2 (V-shaped nodes). This is achieved by providing for the polygonal fields a hard core marked point process representation with individual points carrying polygonal loops as their marks, so that the coupling from the past and clan of ...

Air pollution (AP) is a significant risk factor for public health, and its impact becoming increasingly concerning in developing countries where it causing growing number of health issues. It therefore essential to map monitor AP sources order facilitate local action against them. This study aims at assessing the suitability Sentinel-5 products based on Google Earth Engine (GEE) air pollutants,...

background: kidney transplantation is a preferred treatment for many patients with end-stage renal disease (esrd) and is far more profi table than hemodialysis. analyzing renal transplantation data can help to evaluate the eff ectiveness of transplantation interventions. the aim of this study was to determine the organ survival rate after kidney transplantation during a period of 10 years (marc...

background: to explore a possible rela!onship among blood groups and the prognosis of breast cancer, this case- control study was carried out in arak city, arak province, iran. materials and methods: one hundred and thirty four pa!ents with breast cancer were inves!gated. abo blood groups were obtained from medical records. mul!variate analyses were performed, including size of tumor, axillary ...

We construct random dynamics on collections of non-intersecting planar contours, leaving invariant the distributions of lengthand area-interacting polygonal Markov fields with V-shaped nodes. The first of these dynamics is based on the dynamic construction of consistent polygonal fields, as presented in the original articles by Arak (1982) and Arak & Surgailis (1989, 1991), and it provides an e...
