Present work is aimed at designing, implementing and validating computational procedure for the fluid flow and heat transfer analysis through the annular sector duct. This work will provide the complete heat transfer analysis and will be useful in developing an understanding of controlling parameter characterizing the configuration of annular sector duct. Chapter 1 is devoted to introduction and literature review, whereas, in chapter 2, we have selected a literature problem and discretised that by using two well known techniques finite difference method, (FDM) and finite volume method, (FV M). By comparing the results obtained from both procedures with the literature, we have selected one procedure for further mathematical models of the dissertation. In the chapter 3, we have carried out the study of forced convective Newtonian fluid flow, by considering the two different cases. In the 1st case, we have studied the forced convective flow of Newtonian fluid under the influence of uniform transverse magnetic field, applied perpendicular to the direction of flow. In the 2nd case, we have studied the influence of uniform transverse magnetic field on electrically conducting Newtonian fluid flow through annulus sector duct, filled with Darcy Brinkman porous media. As most of the fluids in nature are non-Newtonian, therefore, to make our model more realistic, we have replaced the Newtonian fluid with the power law fluid. In the chapter 4, we have carried out the study of forced convective power law fluid flow, by considering the four different cases. In the 1st case, we have studied the impact of flow behaviour index, n, on the forced convective flow in both pseudo-plastic and dilatant fluids. In the 2nd case, we have carried out the influence of magnetic field on electrically conducting power law fluid. We have studied the impact of n in both fluids for different value of Ha. In both cases, successive over relaxation, (SOR), method is used to solve the system of algebraic equations, obtained by using the FV M. In the 3rd and 4th cases, we have studied the impact of porosity factor, K, on forced convective flow of power law fluid through an annular sector duct, filled with Darcy Brinkman porous media in the absence and presence of uniform transverse magnetic field. In both cases, we have used the strongly implicit procedure, (SIP), to solve the system of algebraic equation, and compared with SOR method on the based of convergence. To achieve further enhancement in the heat transfer rate, addition of nano scale particles to the base fluid is an established research methodology now a days. Therefore, in chapter 5, we have studied the impact the nano scale particles on the forced convective flow of power law fluid by considering two different cases. Two types of nano scale particle (i.e Copper, Cu and Titanium oxide, TiO2) are used. Finally to make the dissertation wholesome, in chapter 6, we have studied the combined effect of viscous dissipation and Joule heating on the forced convective flow of power law fluid in absence and presence of nano scale particles. At the end of dissertation, we give brief of the future work.
Islam is universal Religion which not only clear with issues related to Muslims but also clarify the rules and regulations to have intinary with Non-Muslims. Islam emphasizes on primary/ basic rules about relationship of Muslims and Non- Muslims Communities; justice, peace, mutual harmony and co-operation. No force conversion and freedom of thought, Non compulsion Of impartiality convenant. Islam forces on mutual existence in according of these rules. So, clash of civilizations can be avoided in the present age.
The use of antimicrobial drugs has decreased the frequency of infectious ailments. But their widespread use has generated drug-resistant microbes, so there is need to develop new rapid acting antibiotics with less side effects. The silver nanoparticles have been recognized as efficient broad spectrum antimicrobial agents. It uses mushroom glucans as reducing and capping agent to decline its toxicity. The present study was primarily, on the nutritional, biochemical and nutraceutical characterization of mushroom and ultimately, on the green synthesis of silver nano-particles with mushroom glucans and then characterization, antimicrobial and biochemical analysis through in vitro and in vivo studies. The four different Pleurotus spps. including P1: Pleurotus ostreatus, P3: Pleurotus sajor-caju, P6: Pleurotus sapidus and P8: Pleurotus columbinus were collected from mushroom culture bank of Medicinal Mushroom Laboratory, Institute of Horticultural Sciences, University of Agriculture, Faisalabad, Pakistan. Proximate analysis of the selected mushrooms depicted the protein (19.07-30.15%), ash (2.1-9.14%), carbohydrate (65.66-82.47%) and fiber contents (38.5-46.3%) were present in significant amounts whereas fats (1.04-6.01%) were in low concentration. All the mushrooms showed potential total phenolic contents (TPC), total flavonoid contents (TFC), DPPH radical scavenging and reducing properties. Selected mushrooms showed DNA protection against H2O2, by use of calf thymus (ctDNA). A moderate antimicrobial potential exhibited by all mushrooms against selected bacterial (E. coli, P. multocida, B. subtilis and S. aureus) and fungal species (A. niger, A. flavus, F. solani and H. maydis). Fatty acids profile by Gas chrometography-Mass spectroscopy (GC-MS) showed that the unsaturated fatty acids were more prevalent over the saturated fatty acids in targeted Pleurotus spps. Quantitative protein analysis depicted h i g h concentration of proteins (33.47-45.78 mg/g) in selected Pleurotus spps. High performance liquid chromatography (HPLC) analysis expressed variable concentration of sugars and organic acids present in the Pleurotus spps. Quantitative ascorbic acid analysis depicted that they were significantly higher (4.90-6.97 mg/g) in chosen Pleurotus spps. High performance liquid chromatography (HPLC) analysis of α-tocopherols and β-carotenes showed that they were present in targeted Pleurotus spps. Macro and micronutrients studies showed that all four Pleurotus spps. have minerals [Na (19.09-39.2 mg/100g) and K (4.84-11.98 mg/100g)] micronutrients [Ca (1.33-11 mg/100g), Mg (1.4-2.1 mg/100g) and P (2.1-4.3 mg/100g)] and xxv trace elements [Cu (10.2-15.42 mg/100g), Mn (2.1-7.4 mg/100g), Zn (37.5-54.6 mg/100g) and Fe (12.1-15.2 mg/100g)] while all were deficient of heavy metals like Pb. Green synthesis of silver nano-particles performed by glucans from selected Pleurotus spps. Extracted glucan and synthesized Glucan-AgNPs confirmed by Ultraviolet-Visible (UV-Vis) spectra. Size of Glucan-AgNPs determined by Dynamic light scattering. The Glucans characterized by Fourier transformation infrared spectroscopy (FT-IR), Scanning electron microscopy (SEM) and X-ray diffraction (XRD) and Glucan-AgNPs were characterized by FT-IR, Scanning electron microscopy-Energy dispersive spectroscopy (SEM-EDS), Transmission electron microscopy (TEM) and XRD. In vitro studies showed that Glucan- AgNPs revealed excellent antimicrobial, biofilm inhibition and anti-cytotoxic potentials. In vivo studies performed on adult albino rats. The glucan-AgNPs significantly restored the physical (Temperature), hematological (Total leukocyte count, neutrophil (%age) count and ESR) and biochemical (C-reactive proteins) parameters elevated after induction of infection. Histological examination revealed that there was no deposition of silver in small intestine, skin, liver and kidney.
