Abstract: One of using flow injection synthesis of Cu(1-y) ZnY Fe2+XO4 is able to estimate the entropy of forming the material, automatically both degree of spinel inversion, magnetic behavior and Seebeck parameter of material can be predicted. Using of Rieltveld refinement of the X-ray de-fraction characterization analysis both the parameter of lattice and oxygen, and cationic distributions can be determined. Furthermore by helping of magnetic characterization measure will be obtained transition magnetic phase of Cu-Zn Ferrite, whether in ferromagnetic or diamagnetic phase. At the phase transition stability disrupted electronic materials, so that behavior can be observed of the thermoelectric behavior materials. All of the parameter able to reveal the Cu(1-x) Znx Ferrite Seebeck behavior. Justification of Seebeck estimation could be done by measurement of thermoelectric voltage use of material bulky that is flanked by two silver electrode reveal that inversion x-0.88, 0.9 give the highest Seebeck behavior. A series of spinel inversions dgree as x = 0.379, x = 0.515 and x=0.57 , only the value of x = 0.379 which shows the potential thermoelectric properties. Test of magnetic material using permagraph shows that on the degree inversion 0.379 there is a change from ferromagnetic to diamagnetic, indicate it has been exchanged the electron state energy. Entropi, which is the stability of crystalline materials determined, is influenced by include, temperature also give contribution increase Seebeck paremeter material. This study as encourager not only developing of Cu-ferrite materials as semiconductor materials, but also as a thermoelectric power material

Abstract: An experiment was conducted to evaluate advance wheat (Triticum aestivum L) breeding lines for yield and yield contributing traits. Fifteen F4:7 bread wheat lines were assessed in randomized complete block design with three replications under normal and late planting conditions. Analysis of variance showed significant (p=0.01) differences among wheat lines for all studied traits. Genotype × environment were significant for days to heading and grain fill duration. Generally, genotypes had varying response to late planting. Decline as result of delayed planting was recorded in days to heading (3.6%), days to maturity (1.8%), grain fill duration (2.7%), grain growth rate (16.3%), 1000 kernel weight (5.3%) and grain yield ha-1(13.6%). Among wheat lines, maximum grain yield (3945 kg ha-1) was produced by Margla/Ghaznavi-5 and Takbeer/Ghaznavi-3 under normal planting followed by Tatara/Takbeer-6 (3890 kg ha-1). Broad-sense heritability estimates were 49, 38, 12, 60, 51, 55% for days to heading, days to maturity, grain filling duration, grain growth rate, 1000 grain weight, and grain yield ha-1. Based on this study, the lines Takbeer/Ghaznavi-3, Takbeer/Ghaznavi-5 and Takbeer/khattakwal-4 were found superior for normal and late plantings.

Abstract: In the present work, different natural clays were used as solid adsorbents for the elimination of the hazardous Acridine Orange AO from wastewater. The adsorption of AO dye at a fixed initial concentration of 100 ppm on the Qwlapalk Clay (QC) and 200ppm on the Commercial Bleaching Clay CBC were carried out. The study was done in a batch system to optimize operation variables; working temperature, time and pH, for the same adsorbent quantity of QC and CBC dye solution. This procedure is particularly suitable for purification of wastewater from Acridine Orange at relatively short period of time and with low cost.

Abstract: Alginate is a family of organic polymeric polysaccharides is composed of two monomer units of guluronic acid (G) and mannuronic acid (M) or both alternating (GGMM). Alginate compound found in the cell walls of brown seaweed in the form of crystals arranged in parallel on fine threads and cellulose in the cell fluid. This study was conducted to obtain alginate products are soluble in water and it has sufficient viscosity. Optimization does on the extraction process to obtain seaweed alginate. The main parameter to be achieved is the efficiency of the process, both technically and economically. In this research, the extraction process has been carried out in stages to make the pH controlled. pH controlled has been carried out with the addition of HCl and Na2CO3. From the research, product characterization and analysis of physical chemistry by analyzing the moisture content, ash content, viscosity, solubility in water and colors. Then do the validation for the resulting alginate compounds using FTIR, LCMS and NMR. Results of 1H and 13C NMR analysis showed ties between the H and C atoms to form a compound with a structure like guluronic acid and mannuronic acid. This data is reinforced by the results of the FTIR analysis showed that functional groups contained in the alginate, and the results are showing molecular weight LCMS analysis of the alginate. From these results it can be concluded that the sample obtained from the extraction of the seaweed is alginate.

Abstract: Mungbean is considered as cash crop because of valuable nutritional profile, short growing season and soil fertility restoration. Usually it is grown on marginal lands in both growing seasons in Pakistan (rabi and kharif). Marginal areas remain deficient in inputs needed to provide optimum conditions to developing plants. Moisture deficiency is one of the major threats amongst prevailing stresses especially during kharif season in Pakistan. It is mandatory to grow drought tolerant mungbean genotypes to minimize the adverse effect of drought. In present study 17 mungbean genotypes were screened for drought tolerance at seedling stage and to find out best selection criterion against drought conditions. Shoot length (SL), root length (RL), root shoot ratio (R/S), stem diameter (S.D), shoot weight (SW), dead leaf %age (DL%), dead over normal leaf ratio (DL/NL), emergence %age (E%) and energy of emergence (EE) were studied. Line graph, biplot graph and principle component analysis were used for evaluation of mungbean seedlings performance at different moisture levels i.e. 80% (T1), 50% (T2) and 30% (T3) of the field capacity (FC). Genotypes AUM25, AUM-38, M-2004, 56-2 and NM-98 at T1, AUM-9, AUM-38, and AUM-25 at T2 and AUM-31 and AUM-25 at T3 were proved most suited at corresponding environments. Genotypes AUM51, AUM-2002, M-2006, AUM-28, NM-58 and AUM-25 performed better under all the three studied environments. Best performing genotypes might be used in future breeding programs to develop drought tolerant mungbean recommended for marginal lands. Parameters corresponding early growth and development proved as best selection standard for low moisture stress tolerance.

Abstract: This paper concerns about some computational aspect of martingale processes in binomial asset pricing models. Mathematica programs are incorporated to get the martingale values, which lead to no-arbitrage option values through first fundamental theorem of asset pricing, for a set of risk neutral probabilities. Numerical example, through Mathematica program, ensures the theoretical fact that if not discounted properly the underlying stock price dynamics doesn’t follow martingale process.

Abstract: In this paper we discuss dynamical properties of a modified Leslie-Gower predator-prey system with quadratic predator harvesting. We show that all solutions of the system are uniformly bounded. The permanence, stability (of equilibrium points) and bifurcations of the system are investigated. The system has at most two equilibria in the interior of the first quadrant and can exhibit Bogdanov–Takens, Hopf, transcritical and saddle-node bifurcations. Depending on the values of parameters, the system may have a stable periodic solution, or a homoclinic loop, or a saddle point, or a stable focus. Biologically, both populations prey and their predators may survive for certain parameter values.

Abstract: Recently enhancing the grid reliability during the peak instant is gained a lot of attentions. In addition, using renewable energy systems to feed remote areas which are not preferred to be fed from the utility because they are far from it is a another goal of many researchers. One out of these loads is the street lighting especially. Therefore, this paper proposes a standalone solar energy-free system for street lighting as there is no power demanded from the grid. The proposed system consists of a PV panel, storage system, LED lamp, power conditioning system (PCS) and the controller which can manage the power direction and system operation. Using LED in lighting applications has many advantages compared to other lamp. It is very efficient (very high efficiency lighting source) and cost effective (the life time is very long compare to other lamps). In additions to, it needs low dc voltage source to be operated. The storage system will be charged during the day time using the available sunlight. On the other hand, during the night time the controller will give a signal to the system to connect the LED lamp to be ready for use. Since the LED needs a low dc voltage to be operated, so a simple dc-dc converter will be enough for this system resulting in decreasing the cost of the overall system. Selected of simulation results have been provided to validate the proposed system.

Abstract: In [1, 2] Fourier Stability Analysis Of Navier-Stokes Equations has been carried out,where non-linearity were incorporated by freezing non-linear terms and obtained optimum smoothing factors which were in a close agreement with practical smoothing factors. In this paper an effort was made to obtain Von-Neumann stability of elliptic type reduced Navier-Stokes equations in vorticity-stream function formulation. Using stream function in cartesian coordinate system we derived the Vorticity transport equation by eliminated pressure term from momentum equations in cross differentiation. The derived equation is classified as a parabolic equation with the unknown vorticity ,!. By considering the definition of the vor-ticity, we derived the equation known as the stream function equation and is classified as elliptic PDE with the unknown stream function , . The stability analysis is carried out by converting stream function equation expressed in non-dimensional form so that the non-linearity is vanished in the equation. With the induction of vorticity and stream function,the in-compressible Navier-Stokes equations are decoupled into one elliptic and one parabolic equation. The Von Neumann stability analysis is carried out for the elliptic equation only. The various numerical experiments using iteratives schemes have been carried out to obtain theoretically op-timal smoothing factors. Results are plotted for amplification factors for a number of unknown parameters.
