introduction: heavy metals are types of elements naturally present in soil or enter into soil as a result of human activities. the most important route of exposure to heavy metals is daily intake of food. crops grown in contaminated soil (due to mining activities, industrial operations and agriculture) may contain high concentrations of heavy metals. also closeness to cities and industrial cent...

this study analyzes wind energy potentials of zanjan province which located in northwest of iran. renewable energy plans are not fully environmentally safe and different renewable energy plans have different environmental impacts. therefore, site selection is an important issue in the wind turbine installation and therefore, selecting an appropriate wind turbine site requires consideration of m...

Methoxypoly(ethylene glycol) Poly(caprolactone) (mPEG–PCL) copolymers are important synthetic biomedical materials with amphiphilicity, controlled biodegradability, and great biocompatibility. They have great potential application in the fields of nanotechnology, tissue engineering, pharmaceutics, and medicinal chemistry. mPEG–PCL copolymers are biodegradable, biocompatible, and semi-crystallin...

AIM Echinococcus and Taenia spp. are important but neglected zoonotic helminths of dogs. Dogs as the most relevant definitive hosts harbor several species of Taenia and Echinococcus simultaneously in their gastrointestinal lumen which are morphologically indistinguishable. In this study, we used a multiplex polymerase chain reaction (PCR) method to identify Taeniid infections which seem to be h...

background: given the increasing importance of suspended particles and reporting weather conditions in the amount of ultraviolet radiation in many countries, in this study, the data of the maximum amounts of pollution by suspended particles with the size of 10, 2.5 and1 microns (pm10, pm2.5, pm1) which were reported in 1-hour time-series and global ultraviolet index (uvi) were used to predict t...
