2. Materials and methods 2.1. Chemicals Zingerone was obtained from Alfa Aesar, Heysham, UK. Cisplatin, Bradford reagent, trichloroacetic acid (TCA), thiobarbituric acid (TBA), reduced glutathione (GSH), glacial metaphosphoric acid (Gmpa), 5,5ˊ-dithiobis-(2-nitrobenzoic acid) (DTNB), proteinase K and agarose were purchased from Sigma-Aldrich Co, MO, USA. All other chemicals and solvents used were of the highest purity grade available. 2.2. Animals Sixty Adult male albino rats (180-200g) were…

In this model no any chemical reaction is considered.(Barba et al.) modelled gasification by considering it to occur in two steps, in the first of which the biomass is decomposed at high temperature to give primary gas and carbonaceous residue and in the second there is modification…

The purpose of this study was to investigate the effect of a system that automatically adjusting hydrogen peroxıde Colloıdal-Ag dose to reduce colonization and growth of heterotrophic bacteria in dental unit waterlines and wastewaters. Thirty dental units were assigned into three groups with respect to the protocol employed: Group 1: 10 units were selected for automatic administration. Group 2: 10 units were selected for manual administration and Group 3: 10 units served as controls. Water…

1 enzyme Enzymes are biological catalysts. A protein compound Energy can reduce the carbon reaction. Enzymes to accelerate specific types of reactions. And the kind of substance that reacts. 2.1.1 catalysis of enzymes E is a catalyst (enzyme). S is a precursor called chop, nitrates and substance P is a product. E + S ---------------> E S ---------------> E + P. Complexometry 2.1.2 Factors affecting the enzyme. 1) What type of controlled…

recently, Pcs have found high-tech applications in electrophotography and ink-jet printing and as photoconducting agents in photocopying devices. In addition, their novelty is rapidly growing in other fields where they are used as sensing elements in chemical sensors, electrocatalysts, liquid crystals, electrochromic display devices, information storage systems, semiconductors, functional polymers and molecular metals, among others. They have also found use in photodynamic therapy (PDT).…

Figure 12A shows the contact time vs. the removal percentage curves. It can be observed that the uptake of Pb2+ ions was very rapid and a large amount of this toxic ion was removed within a few minutes (2 min). The fast adsorption process may be the result of the fast kinetics of active sites on the surface of the synthesized composite in the adsorption of pb2+ ions along with a large number of accessible active adsorption sites on the uncovered absorbent surface [36]. After this time…

Biodiesel production is usually expressed through the process of trans-esterification reaction. Recently, homogeneous catalysts are broadly preferred for biodiesel production in eminent scale operation. Still, they are toxic, highly flammable and corrosive in nature [1]. Boey et al. analysed the purpose of the waste cockle shell from palm olein oil in biodiesel production of Anadara granosa. At 900 °C the waste shell was calcined for 2 h that mainly compiled of 71% of Ca to develop an active…

5. SUMMARY We have derived Laplace's equation for steady-state water flow in two dimensions and have explained how the equation is solved by three Relaxation Methods: Jacobi, Gauss Siedel and Successive Over-Relaxation on a discrete 20 10 grids. The numerical method was illustrated by a Matlab programming code. 6. References [1] John D. Anderson, JR (1995). Computational Fluid Dynamics: The Basics with Applications .McGraw Hill, Inc.

Sterile Saline (0.9% w/v NaCl) Dissolve 9.0gm of NaCl in 1000ml water and dispense 9.0ml of the solution into 20ml test tubes. Autoclave the tubes as per the validated cycle and cool to room temperature. Sterile saline with polysorbate 80: Dissolve 9.0gm of NaCl in 1000ml water and add .5gm of tween 80 to the resulting saline solution, dispense 9.0 ml of the solution into a number of 20ml test tubes. Autoclave the tubes Preparation of Inoculums and its Standardization: 1) Take loop full of…

3.0 Hypothesis I assume that as the solution is treated with higher amount of fertilizer, the Spirulina cells will reproduce better and survive for longer time as there will be higher amount of nutrients supplied. Therefore, it is assumed that the Spirulina-concentration of the trials treated with 1.0mL fertilizer will be higher than those treated with 0.5mL or 0.0mL. Although wastewaters contain elements which are vital for the Spirulina growth, as it contain other unknown substances as well,…
