asthma environmental triggers play important roles in severity of disease. passive smoking could exacerbate asthma symptoms and enhance the decrease in lung function. cotinine levels could be a reflection of passive exposure to the cigarette both in adults and pediatrics. the aim of this study was to determine degree of association of asthma severity and cotinine level as a marker of passive sm...

leishmaniasis is a common parasitic disease in tropical and subtropical areas of the world. police personnel deployed in the suburbs and rural areas are the most often exposed to the potential risk of cutaneous leishmaniasis. furthermore, since the same police personnel are sent on duty to other places, their migrations can also play a considerable role in the transmission of this disease to th...

introduction : adverse health effects of exposure to environmental tobacco smoke (ets) among non-smokers have been studied occasionally in developing countries. the aim of this study was to determine the effects of exposure to ets on outcome in pregnancy methods: in this descriptive and analytical study 600 non-smoking women delivering a singleton live baby were studied in delivery room in haja...

objectives: specific language impaired children, despite being normal in cognitive and neurological characteristics, and also normal levels of hearing, experience multiple problems in syntax comprehension. this study compared the passive comprehension as one of syntactic structures in persian-speaking typically developing children and specific language impaired children. methods: 10 children wi...

Plants are not passive victims of the myriad attackers that rely on them for nutrition. They have a suite of physical and chemical defences, and are even able to take advantage of the enemies of their enemies. These strategies are often only deployed upon attack, so may lead to indirect interactions between herbivores and phytopathogens. In this study we test for induced responses in wild popul...

A real amplification of an initial enantiomeric excess can be detected when two amino acids are sublimed at high temperature, even if one of the components is a racemic compound that does not convert into a conglomerate by sublimation.

There is a strong case to be made out against psycho-analysis, but Salter fails to make it. Even when he does present convincing instances of the contradictions within the theory, he spoils his case by his uncritical thinking and his sweeping condemnations. For example, he boldly and rashly rejects outright such concepts as projection and sublimation as being utterly useless. It would be more a...

Isothermal close space sublimation, a simple and low-cost physical vapour transport technique, was used to infiltrate ZnTe and CdSe semiconductors in porous silicon. The structure of the embedded materials was determined by X-ray diffraction analysis while Rutherford backscattering spectra allowed determining the composition profiles of the samples. In both cases, a constant composition of the ...

Tetranitratoethane (C2H2N4O12), which has an oxygen content of 70.1% was synthesized by nitration of monomeric glyoxal using N2O5 and purified by sublimation. Single crystals could be grown from CH2Cl2/pentane and were used to determine the structure by X-ray diffraction. Several energetic parameters and values were also established.

Charge transport in organic thin film transistors takes place in the first few molecular layers in contact with the gate dielectric. Here we demonstrate that the charge transport pathways in these devices are extremely sensitive to the orientational defects of the first monolayers, which arise from specific growth conditions. Although these defects partially heal during the growth, they cause d...
