Phenol contamination in ambient air is a factor which creates health risks for children living zone influenced by emissions from ferrous metallurgy enterprise. Our research goal was to assess specific hapten sensitization under excessive aerogenic exposure phenol. We performed hygienic assessment of pollution on territories pre-school facilities located at various distances the examined enterpr...
Nowadays, given the widespread use of global projection systems such as the UTM projection system in surveying projects relying on elliptic referents, finding a suitable composite scale factor for each project to implement construction projects using mapping equipment such as devices Total station is necessary. Unfortunately, today the method of calculating and assigning average composite scale...
Arsenic is a metalloid, which may be found in surface water, ground plants and rocks. In high concentrations, its compounds are considered to genotoxic carcinogenic. Its levels drinking water must regularly monitored controlled. The objective of study was determine the concentration arsenic with reference WHO limits from selected boreholes Nairobi County, Kenya. Water randomly sampled total 63 ...
the ability to speak two languages in the world is a remarkable achievement. there is a good reason to believe that bilingualism is the norm for the majority of people in the world because 70% of the earth’s population are supposed to be bilingual or multilingual. various investigations have shown that the native language impacts foreign word recognition, and this influence is adapted by the de...
The primary goal of the present study was to employ confirmatory factor analysis to compare two theoretical models regarding the factor structure of disgust (N=307). The two-factor model of Animal Reminder and Core disgust proposed by Rozin et al. (2000) demonstrated superior model fit over a one-factor model that has been implicated in prior research. However, contrary to theoretical predictio...
The SABER instrument (Sounding of the Atmosphere using Broadband Emission Spectroscopy) is a cryogenic infrared sensor on the TIMED spacecraft with stringent molecular and particulate contamination control requirements. The sensor measures infrared emissions from atmospheric constituents in the earth limb at altitudes ranging from 60 to 180 km using radiatively-cooled 240 K optics and a mechani...
Background: Existence of bacterial host cell DNA contamination in biopharmaceutical products is a potential risk factor for patients receiving these drugs. Hence, the quantity of contamination must be controlled under the regulatory standards. Although different methods such as hybridization assays have been employed to determine DNA impurities, these methods are labor, intensive and rather exp...
At the University Hospital of Besançon (département of Doubs, France), an unusually high number of patients were hospitalized for hepatitis A during the 1999-2000 period, some of whom had not travelled abroad. This prompted us to conduct an investigation on a population basis and search for clusters of cases possibly related to local sources of contamination. Accordingly, case definition was re...
Introduction: Photon contamination is a restriction on treatment with electron that increase dose to healthy tissue below the tumor. The aim of this study is to reduce the photon contamination using a magnet system. Materials and Methods: A mini-applicator equipped with two neodymium boron permanent magnets was designed which make it possible to adjust the d...
