The growth of a pathogenic Enterococcus-like bacterium (strain KM002) isolated from A4acrobrachium rosenbergii was examined in brain heart infusion broth (BHIB) at different pHs, temperatures, and NaCl concentrations. It grew from pH 3 to 10 (optimum 7 to 8), from 5 to 45°C (optimum 25 to 30°C) and from 0.5 to 6.5 % NaCl (optimum 0 5 to 1.0%). M. rosenbergii was then challenged by ~njection of ...

The aim of the present research is studying the effect of potassium permanganate addition on the pre-oxidation and coagulation of the surface water. River Nile and El Rayah El Tawfeky of Benha city, Egypt were the surface water supply used in this research. The results showed that El Rayah El Tawfeky raw water had higher turbidity concentration and humic acids absorbance (8.5 NTU and 0.024, res...

Background & Aims of the Study: Coagulation is an essential process for the removal of fine particulate matter in water treatment. Polyaluminium ferric chloride (PAFC) is a composite inorganic polymer of Aluminium and ferric salt. This study was conducted to find out the optimum coagulation conditions for the removal of turbidity, color and organic matter (UV absorbance) in low to mediu...

The effect of nitrogen (N14) implant into dual-doped polysilicon gates was investigated. The electrical characteristics of sub-0.25m dual-gate transistors (both pand n-channel), MOS capacitor quasi-static C V curve, SIMS profile, poly-Si gate Rs, and oxide Qbd were compared at different nitrogen dose levels. A nitrogen dose of 5 10 cm 2 is the optimum choice at an implant energy of 40 KeV in te...

Aim: The aim of this study is to find an optimum material to protect garment for protection against 99Tcm radionuclide.Materials and Methods: Monte Carlo simulation code was applied to investigate radiation attenuation of 13 shielding materials including: Ba, gray Sn, white Sn, Sb, Bi, Bi2O3, BaSO4, Sn/W, Sb/W, Pb and W with thicknesses of 0.5 and 1 mm to determine an optimum protective garment...

Background: Radiation-sensitive polymer gels are among the most promising three-dimensional dose verification tools and tissue-like phantom developed to date.Objective: The aim of this study is an investigating of percentage depth dose enhancement within the gel medium with used of conformal distribution gold nanoparticle as contrast agents by high atomic number material.Methods: In this work t...

In Bangladesh, potato (Solanum tuberosum L.) lacks optimum quality for export or processing industries. Optimum utilization of specific plant nutrients can improve quality. The experiment was conducted to evaluate the best dose(s) phosphorus in combination with potassium sources as they affect tuber consisted factors: dose(4); P1 = 200 kg ha-1 TSP @ 42.55 P; P2 220 46.81 P, P3 240 51.06 P and P...
