During analysis of the relation of quasars to galaxies in the 2dF deep field a concentration of quasars was noted. Most striking was the closeness in redshift of 14 quasars about the mean redshift z = 2.149 with a range of ±.018. The cluster in spite of its high redshift subtends an area of diameter more than 2.3 degrees on the sky. At conventional redshift distance its diameter would be 181 me...

We examine the geographic co-location of university research and industrial R&D in three technology areas. While we find strong evidence of co-location of these vertically connected activities, regional economies appear to vary markedly in their ability to convert local academic research into local commercial innovation. We develop and test the hypothesis that the presence of a large, local, R&...

Alternaria from different Allium plants was characterized by multilocus sequence analysis. Based on sequences of the β-tubulin (BT2b), the Alternaria allergen a1 (Alt a1), and the RNA polymerase II second largest subunit (RPB2) genes and phylogenetic data analysis, isolates were divided into two groups. The two groups were identical to representative isolates of A. porri (EGS48-147) and A. vanu...

Alumina composites containing in-situ-formed hexaluminate (LaAl,,018, LaMgAl,,O,,, SrAl12019, and Mg,NaAl,,O,) platelets can be pressureless-sintered to high density. The grain morphology of the aluminates can be controlled by composition. A peak toughness 50% higher than that of alumina is obtained at 30 vol% aluminates, with a modest reduction (10%) in hardness and Young’s modulus. Although c...

امروزه ارتباط کمّی ساختار - خاصیت (qspr) برای مطالعه ی وابستگی خواص مختلف فیزیکوشیمیایی ترکیبات با ساختار مولکولی استفاده شده است. در بخش اول این پروژه، از رگرسیون خطی چندگانه (mlr) به عنوان یک روش خطی و از شبکه ی عصبی مصنوعی (ann) به عنوان روشی غیر خطی برای پیش بینی ثابت هنری 333 ترکیب آلی استفاده گردید. سری داده-ها به سری های آموزش (263 ترکیب)، آزمون (40 ترکیب) و ارزیابی بیرونی (30 ترکیب) تقسی...

This paper reports an unintentional death involving the administration of methoxetamine [2-(3-methoxyphenyl)-2-(ethylamino)-cyclohexanone] and offers some reference values from living drug abusers. Methoxetamine is a new recreational drug with a similar structure to ketamine. The deceased was a 26-year-old male with a history of drug abuse; he was found lying on the floor in his apartment. Seve...

Cite this article: Soto R B. Dynamometer Measurements of Grip Strength in Frail Elderly Inpatients. J J Intern Medicine. 2016, 2(1): 018. Sarcopenia and frailty are two clinical entities that generate loss of independence. Sarcopenia is characterized by loss of skeletal muscle mass and strength and is a risk factor for fraility and physical disabilities [1]. To diagnose fragility must is necess...

Methods We performed a systematic literature analysis in PubMed (deadline: 15 January 2010, terms “juvenile idiopathic (rheumatoid) arthritis”, “therapy”, limits: “humans”, “published in the last 3 years”, “all child 018 years”, “clinical trial”) and evaluated relevant studies for quality of methodology. A formal consensus process, i.e. Nominal group technique and Delphi method, was conducted a...

We calculate the light quark spectrum of lattice QCD in the quenched approximation using Kogut-Susskind quarks. By combining results for different lattice spacings, several volumes and ve quark masses, we are able to take the light quark mass, innnite volume, continuum limit. When we use non-linear chiral extrapolations, we nd that the nucleon to rho mass ratio is m N =m = 1:254 0:018 0:027, wh...
