Coal, bottom ash and fly ash samples were collected from three different coal-fired thermal power plants in India and subjected to gamma spectrometry analysis for natural radioactivity contents. The results of present study show that fly ash and bottom ash contains two to five times more natural radionuclides than feed coal. None of the fly-ash and bottom ash samples had radium equivalent activ...

when a plant is initially transformed, the transgene is present in a heterozygous form. Since white clover is outcrossing and predominantly self incompatible it is necessary to cross primary transgenic plants to produce an BC1 population, then intercross BC1 transgenic plants to produce an F2 population. The F2 population will have a highly heterogeneous genetic background and a variable alleli...

Over the past few decades there has been some discussion concerning the increase of the natural background radiation originated by coal-fired power plants, due to the uranium and thorium content present in combustion ashes. The radioactive decay products of uranium and thorium, such as radium, radon, polonium, bismuth and lead, are also released in addition to a significant amount of 40K. Since...

Protein N-terminal methionine (Met) excision (NME) is carried out by two types of Met aminopeptidases (MAPs), MAP1 and MAP2, in eukaryotes. Three enzymes, MAP1A, MAP2A, and MAP2B, have been identified in the cytoplasm of Arabidopsis (Arabidopsis thaliana). MAP transcript quantification revealed a predominance of MAP2B and developmental and organ-specific regulation of both MAP1A and MAP2s. By c...

this research investigate the potential of rhizobium leguminosarum b.v .phaseoli to improve growth and nutritional status of common bean (akhtar cultivar) at three levels of salinity of s0, s1 and s2 (0, 35 and 70 mm sodium chloride, or 0, 3 and 6 ds/m, respectively). the greenhouse experiment was conducted as a factorial design in randomized completely with three replications by using the ster...

On March 11, 2011, a gigantic earthquake struck eastern Japan. Utilities such as electricity, water, gas and telecommunication were interrupted. In Koriyama, the City Hall collapsed and government administration offices had to be moved to a nearby baseball stadium that had been designed to include facilities for use during a pandemic. An operations center was set up in t...

background: medicinal plants use is growing in iran and controlling their quality in terms of contamination with toxic metals is critical. city of arak, due to its large industrial plants, is one of the most polluted cities of iran these pollutants can be transferred to the farms. methods: in this study, concentrations of metals such as aluminum, arsenic, lead and cadmium are measured by atomic...

Background: Medicinal plants, as a complementary medicine, have been used to treat various diseases since ancient times. These plants have numerous beneficial applications and are the source of certain conventional drugs. In diseases such as stroke and ischemia, which are caused by several factors, abnormal coagulation is an important causative factor. Accordingly, novel and effective therapies...

Background: Dermatological disorders affect people in all age groups and prevail all around the globe. In this regard, medicinal plants play a significant role as they are usually the first line of treatment in dermatological disorders. Because traditional healers in Bangladesh know little about the use of plants to treat different skin diseases, we carried out an ethnobotanical survey of medic...

Background: Measurement of background radiation is very important from different points of view especially for human health. The aim of this survey was focused on determining the current background radiation in one of the highest altitude regions ( Zagros Mountains ), Chaharmahal and Bakhtiari province, in the south west of Iran . Materials and Methods: The outdoors-environmental monitoring exp...
