cu-mo and cu-ti contact structures were fabricated on multi-crystalline silicon substrates to provide a low resistance ohmic contact. deposition steps are done in an excellent vacuum chamber by means of electron beam evaporation and samples are then annealed for the realization of an efficient alloy layer. the effects of process parameters such as film thickness, annealing duration and temperat...

background: the purpose of this study was to evaluate the levels of zinc (zn), copper (cu), iron (fe) and zinc/ cop­per ratio in the serum of patients with cutaneous leishmaniasis in qom province, center of iran. methods: serum levels of zinc and copper were determined by flame atomic absorption spectrophotometer and serum iron concentration was measured by using an auto analyzer. the study gro...

We recently determined the genome sequence of the Coccolithoviridae strain Emiliania huxleyi virus 86 (EhV-86), a giant double-stranded DNA (dsDNA) algal virus from the family Phycodnaviridae that infects the marine coccolithophorid E. huxleyi. Here, we determine the phylogenetic relationship between EhV-86 and other large dsDNA viruses. Twenty-five core genes common to nuclear-cytoplasmic larg...

Membrane filtration fouling has become a significant issue that restricts its wide application. The electrocoagulation (EC) technique combines variety of synergistic pollutant removal technologies (including flocculation, redox, and air flotation), which can be an ideal pretreatment process for membrane filtration. In this work, novel Cu2+-doped polypyrrole-coated stainless steel mesh (Cu/PPy–S...

Background: Research is yet to elucidate adolescent polysubstance use profiles among youth with early-onset cannabis (CU; ?15 years). The present study aimed fill this gap in the literature and determine whether CU outcomes early adulthood are best explained by per se, or its resulting profiles. Methods: Participants were N = 794 (56% females) from Québec Longitudinal Study of Child Development...

Tumor volumes measured at the time of initial therapy, during the 28 days following treatment, and following subsequent courses of therapy for 29 patients with small cell carcinoma of the lung were determined from serially measurable roentgenographic lesions. Tumor-halving times were calculated following initial therapy, and the proportions of pretreatment tumor volumes were evaluated within 28...

BACKGROUND The effectiveness of corticosteroids in antihistamine-resistant chronic urticaria (CU) is widely accepted although large studies on their use in this disease are lacking. OBJECTIVE To assess the proportion of patients with antihistamine-resistant CU that respond to a course of corticosteroids. METHODS We studied 750 adult patients with CU and prescribed a course of oral corticost...

UNLABELLED The P300 results from focusing attention on rare stimuli in the midst of other frequent stimuli; it tests recent attention and memory, both of which depend on discriminating among verbal or nonverbal stimuli. AIM To compare the P300 with verbal and nonverbal stimuli in normal-hearing adults. MATERIAL AND METHOD A prospective study was made of 15 male subjects aged from 22 to 55, ...
