Soybean is a high valuable crop of Vietnam and many other countries. The ability soybean plants in nitrogen fixation soil improvement attributed to their symbiosis with different rhizobia the root nodules. It has been well documented that members genus Rhizobium are most effective nodulation legumes. Recently, oder minimize undesired accumulation agro-chemicals metal salts soil, nanotechnology ...

The varied diet of European starlings (Sturnus vulgaris L.) can present challenges when working with starlings in experimental testing and holding situations and should be taken into account when testing repellents applied to food. Our purpose was to evaluate an anthraquinone-based repellent (Arkion Life Sciences, New Castle, DE, USA; active ingredient 50% 9,10-anthraquinone; hereafter anthraqu...

This study was carried out to examine heavy metals concentration in water and sediment of upstream and downstream of the entry of the sewage to the Tembi River, Iran. Samples were collected from upstream and downstream and were analyzed for Cd, Cr, Cu, Fe, Pb, Ni, and Zn by atomic absorption spectrophotometer. The results indicated that the average concentration of the metals in water and sedim...

A mine-tailings spill occurred on the island of Marinduque, Philippines, on 24 March 1996. Originating from the Marcopper Mine, tailings sludge flowed down the Boac River abruptly and during subsequent storm events. Most of the tailings material has since accumulated in the nearshore environment along the western coast of the island. Nineteen sediment cores were collected from this site and ana...

This research was conducted to determine levels of heavy metal pollution in the years 2003-04. in this research, samples of grass and soil taken from green areas in 8 different areas of konya city centre were used as material. The samples were obtained from factory gardens, areas experiencing heavy traffic and residential areas. The changes in analysis results of heavy metal levels (Pb, Cu, zn,...

Analysis of gunshot residue (GSR) is a crucial evidences for a forensic analyst in the fastest way. GSR analysis insists a suitable method provides a relatively simple, rapid and precise information on the spot at the crime scene. Therefore, the analysis of Cu(II) in GSR using cyclic voltammetry (CV) on screen printed carbon electrode (SPCE) is a better choice compared to previous alternative m...

Plants and plant extracts (PPEs) have gained increasing interest as feed additives and possible replacing antibiotics for pig productions. The effects of dietary Chlorella vulgaris (1%), sodium alginate (0.1%), inulin (1.5%), and a mixture of essential oils (0.04%) supplements on immune response, and bioavailability of some micronutrients (iron − Fe, copper − Cu, manganese − Mn, and zinc − Zn) ...

Nanocrystalline semiconducting thin films of copper sulphide (Cu2S) were deposited by novel chemical route using aqueous solution of 0.1 M copper chloride, 0.05 M thiourea, complexing agent 10% aqueous ammonia (NH3) and hydrazine hydrate. The characterization and gas sensitivity of as deposited Cu2S thin film sensor have been investigated. The as deposited Cu2S thin films were observed to be ve...

A total of 225 pigs (PIC 327 × 1050, initially 25.5 lb) were used in a 21-d trial to evaluate the effects of copper source and level on nursery pig growth performance. Pens of pigs were balanced by initial BW and randomly allotted to 1 of 5 dietary treatments with 9 replications per treatment. The 5 corn and soybean meal-based diets were arranged in a 2 × 2 + 1 factorial with main effects of co...
