ISO mid-infrared absorption data helps to distinguish between radiative and collisional pumping mechanisms in 1612MHz OH masers in various environments. Archive data of OH absorption at 34.6 and 53.3 μm shows different behavior and different pumping rates for different types of maser sources. 1. Mid-Infrared absorption in 1612MHz OH masers Mid-infrared spectroscopy by the Infrared Space Observa...

The definition and basic properties of OH-type and OH-cotype of operator spaces are given. We present operator space versions of Maurey’s extension theorem and generalized little Grothendieck’s theorem in terms of these new notions. We also observe that “OH-cotype 2” in this paper is equivalent to the previous definition of “OH-cotype 2” of G. Pisier.

abstract background: vitamin d deficiency is implicated in a wide range of pathological situations including cardiovascular diseases. this study aimed to investigate the association between serum 25-hydroxy vitamin d (25(oh)d) and risk factors of metabolic syndrome and cardiovascular diseases. methods: the cross-sectional study was conducted on 169 adults (88 males, 81 females) aged 19-52 years...

Introduction: The present study aimed to compare the cleaning efficacy of passive ultrasonic irrigation (PUI), self-adjusting file (SAF), EndoVac, and conventional syringe irrigation (CSI) techniques on Ca(OH)2 removal from the root canal. Methods: This study was conducted on the mesial roots of 36 human mandibular molar teeth. After 1 month, the Ca(...

Andrew Tanenbaum and his textbooks – e.g. on Operating Systems, Computer Networks, Structured Computer Organization and Distributed Systems, to name but a few – have had a tremendous impact on generations of computer science students (and teachers at the same time). Given this, it is striking to observe that this comprehensive body of work apparently does not provide a single line on a research...

We also studied this relation more than 30 years ago in 60 pairs of maternal and cord blood, and showed such a relation; ours was one of the first published studies on this subject2. Calcium, phosphorus, and alkaline phosphate levels were also assayed, and were repeated in babies of about one month of age. Maternal and cord 25-OH-CC levels were found lowest in winter months when compared to mot...

background: there is a known inverse association between solar radiation and the prevalence of multiple sclerosis (ms). some studies have investigated the link between vitamin d and ms. the aim of this study was to investigate the possible association between serum 25(oh) vitamin d3 concentration and the severity of disease in iranian patients with ms. methods: patients with relapsing-remitting...

we investigated the association between serum 25(oh) d levels and depressive symptoms in patients with major depressive disorder (mdd).eighty-five adults, 44 drug free patients with mdd and 41 apparently healthy controls, participated in the study. the hamilton depression rating scale was used to assess severity of major depression. mental health of the controls was assessed according to dsm-iv...

a facile mechanochemical-based method for synthesis of copper oxide (cuo) nanoparticles is here by introduced. for this purpose, copper hydroxide powder was synthesized through a facile solution method (cuso4 + 2 na(oh) → cu(oh)2 + na2so4) after which milling of as-prepared cu(oh)2 precursor and nacl resulted in the mechanochemical dehydration of cu(oh)2 and dispersion of cuo nanoparticles into...

background: vitamin d is an important factor responsible for many physiologic functions. vitamin d deficiency is associated with increased risk of neurodegenerative disease. the level of vitamin d in iranian patients with parkinson's disease and its relationship with severity of symptoms and signs were evaluated in this study. methods: eighty-three patients with parkinson's disease (pd) were re...
