Abstract Groundwater contamination is a critical issue in Hanoi because it affects the water supply and treatment of crowded city. This study aimed to explore groundwater quality across whole area city identify potential sources. 206 samples were collected Holocene Pleistocene aquifers during two consecutive seasons (rainy 2015 dry 2016) assess understand which elements can be used as tracers f...

concentrations of major nutritional and trace elements (ca, p, mg, na, k, fe, zn, cu, mn, se,co, cr, ni, sr, ba) and toxic heavy metals (cd, pb) were analyzed in the meat of limousin, red angus andsalers bulls. elements were determined using inductively coupled plasma emission atomic spectrometry. theconducted research showed that the meat of compared breeds differed in the concentrations of cu...

The ability of transposable elements to mobilize across genomes and affect the expression of genes makes them exceptional tools for genetic manipulation methodologies. Several transposon-based systems have been modified and incorporated into shuttle mutagenesis approaches in a variety of organisms. We have found that the Mos1 element, a DNA transposon from Drosophila mauritiana, is suitable and...
