In this study removing heavy metals, Cr (III), and Pb (II) from wastewater, Microorganism Trichoderma sp. biosorption was performed using removal taken into account. For study, 3^3 Factorial Experiment Designs were used, temperature (°C), biosorbent dosage (g/L), pH selected as the main factors for metals three levels of these determined low, medium, high. which carried out to increase metal ef...

Controlled release systems can modify the rate of drugs and direct them to specific sites action, making more effective and/or reducing adverse effects. The objective this study was investigated, poly(β-hydroxybutyrate) (PHB) poly(ε-caprolactone) (PCL) nanospheres improve delivery Simvastatin (SIM). Nanospheres were prepared by emulsion/evaporation technique solvent, varying amount SIM added. q...

Because of complex interactions among the components of PCR and the wide and increasing variety of applications in which this technique is used, optimization is necessary for every reaction. Here we describe the use of experimental design techniques (2k fractional factorial design and central composite design) to attain easier, quicker and cheaper PCR optimization of DNA from blood spots. By de...
