In the interstellar medium (ISM), complex organic molecules that contain thiol group ($-$SH) play an important role in polymerization of amino acids. We look for SH-bearing chemically rich solar-type protostar IRAS 16293-2422. After extensive spectral analysis using local thermodynamic equilibrium (LTE) model, we have detected rotational emission lines trans-isomer monothioformic acid (t-HC(O)S...
جنگلها و مراتع از اموال عمومی و یا به تعبیر فقها و قانون اساسی از جمله انفال محسوب شده است. در سال 1341 با تصویب قانون ملی شدن جنگلها و مراتع عرصه و اعیانی کلیه جنگلها و مراتع و بیشه های طبیعی و اراضی جنگلی کشور در زمره اموال عمومی و متعلق به دولت اعلام گردید و تصرفات و اسناد مالکیت افراد بی اعتبار تلقی شد.البته در قانون مذکور بخشی از عرصه اعیانی مجاور و محاط جنگها ومراتع بنا به ملاحظاتی به عنو...
Studies of protein-bound (PB-SH) and nonprotein bound sulfhydryl group (NP-SH) concentrations in tissues under various conditions is a prerequisite to understanding the role of sulfhydryls in living organisms. Many methods have been developed for the measurement of sulfhydryl groups, but these have been concerned chiefly only with the estimation of NP-SH in biological fluids or total SH groups ...
Mumps virus (MuV), a rubulavirus of the paramyxovirus family, causes acute infections in humans. MuV has seven genes including a small hydrophobic (SH) gene, which encodes a type I membrane protein of 57 amino acid residues. The function of the SH protein is not clear, although its expression is not necessary for growth of MuV in tissue culture cells. It is speculated that MuV SH plays a role i...

BACKGROUND It is notable that sitting height (SH) correlates with blood pressure (BP) in children and adolescents of developed countries. However, little is known about the relationships between SH and SH to height ratio (SH/H) with BP in South African children from middle and upper socio-economic groups. The purpose of this study was to compare SH and SH/H of private school attending children ...
I. Kontoyiannis Appeared in IEEE Trans. Inform. Theory, 43, pp. 1339 1341, July 1997. Abstract { Shannon's celebrated source coding theorem can be viewed as a \one-sided law of large numbers." We formulate second-order noiseless source coding theorems for the deviation of the codeword lengths from the entropy. For a class of sources that includes Markov chains we prove a \one-sided central limi...
PURPOSE Social isolation is associated with suicidal ideation (SI) and self-harm (SH) among adolescents. However, the association between preference for solitude (PfS), SI, and SH is unknown. The prevalence of adolescents who have both of PfS and social isolation and the risks for SI and SH among them are also unknown. METHODS Information on PfS, social isolation, SI, and SH was collected in ...
We present a statistical investigation of the effects interplanetary magnetic field (IMF) on hemispheric asymmetry in auroral currents. Nearly 6 years measurements from Swarm A and C satellites are analyzed. Bootstrap resampling is used to remove difference number samples IMF conditions between local seasons hemispheres. Currents stronger Northern Hemisphere (NH) than Southern (SH) for B NH (B ...
