Background: Heavy metals contaminations are recognized as the serious risk to our environment. The aim of the present study was to analyze heavy metals residue in cultivated mango samples from Iran. Methods: Totally, 72 mango samples were randomly collected among six different mango genotypes cultivated in Southern Iran from June to July 2015. Lead, chromium, cadmium, and arsenic were determin...

BACKGROUND The study aimed to establish the prevalence of heavy drinking, evaluate correlations between heavy drinking and socio-demographic factors, physical and psychiatric conditions, and assess the impact of heavy drinking on quality of life and days of work-loss. METHODS Data from a nationally-representative cross-sectional sample were used. The sample comprised 6616 community-dwelling S...

During recent years, the study of exotic hadrons including tetraquarks and pentaquarks has attracted a lot interest, more studies are in progress experimentally theoretically. It is well known that at sufficiently large transverse momentum dominant production mechanism for standard heavy (mesons/baryons) actually fragmentation so same also proposed hadrons. This work first attempt to direct qua...

We present a detailed analysis of the use of heavy quark fragmentation into heavy hadrons for testing the heavy quark effective theory through comparison of the measured fragmentation parameters of the c and b quarks. Our analysis is entirely model independent. We interpret the known perturbative evolution in a way useful for exploiting heavy quark symmetry at low energy. We first show consiste...

. Abstract— The masses and distance configurations of the ground and excited states of heavy – charmed and bottom baryons J =1/2 ,3/2,containing a single heavy quark and a light diquark are studied within HQS limit of the HQLD sector of NRQCD framework. We find how the average distances between the heavy quark and the center of mass of the light diquark are smaller than the size of the light di...
