Sediment samples from the Tisza River in Serbia were investigated for possible TENORM pollutants. The radionuclide content of the samples was determined by means of low-level high-resolution gamma-spectroscopy. In addition to the members of the natural radioactive chains of (238)U and (232)Th and the natural (40)K, Chernobyl origin (137)Cs was detected in 26 of the 28 samples tested. The higher...

yazd asfordi phosphate rock (pr) was partially acidulated at five levels (0, 40, 60, 80, 100%) for increasing the relative agronomic effectiveness (rae) of canola (brassica napus l.), var. rgs in two calcareous and non-calcareous soils. the partially acidulated phosphate rock (papr) was compared vs. the standard fertilizer (triple superphosphate) in two levels (50 and 100 mg p/kg). this study w...

Abstract The improvement of water quality through aquatic plants’ nutrient uptake is one the crucial elements in achieving a sustainable ecosystem. Water affected by variety variables, including dissolved oxygen concentrations, overabundance, bacterial populations, salt content, and number suspended particles water. This experiment was performed to evaluate biological biochemical characteristic...

The impending phosphorus crisis Phosphorus is a nutrient essential to all living organisms, and thus, it is essential in food production for humans. Although it is the eleventh most abundant element on earth, phosphorus never occurs in its pure form and is always bonded with other elements forming other compounds, such as phosphate rock. More importantly, much of the phosphorus in soil is not a...

The aimed was to determine income and habits maize farmers using fertilizers, as well role fertilizers soil amendments increasing growth crops. This research carried out 2 experimental stages, first stage farmer interviews second a trial fertilizer types field factorial form, on various macro micro for Pioneer 32’s maize, incl...

PURPOSE The rate of hepatocellular carcinoma (HCC) is increasing worldwide, including in Egypt. Hepatitis B (HBV) and C (HCV) viruses are major risks. Non-B non-C HCC was reported in some countries. We investigated non-B non-C HCC-independent risk factors and associated profiles in viral hepatitis endemic region. METHODS In a consecutive series, 281 patients were diagnosed with HCC and receiv...

AIM The effects of N-P-K fertilizers in the form of urea, single super phosphate and muriate of potash on development of free-living stages of Haemonchus contortus were studied. MATERIALS AND METHODS Five parasite free experimental plots of 1 m×1 m area, each of paddy leaves (15-day-old) and an equal number of Cynodon dactylon grass were infested with about 10×104 eggs/ml phosphate buffer sal...
