More than 75 percent of Iran is located in arid and semi-arid and faces many hydrological constraints that often are attributed to the lack of rainfall and rainfall distribution. This issue is locating suitable areas for rain water harvestingin Birj and plain however it ismore importance in poor farming communities that are dependent on rain-fed cultivation. To determine the areas those are prone to runoff collection used from a Decision Support System (DSS) and Geographic Information System (GIS)to identify a logical process in relation to harvesting the rainfall and Within this system utilization from Model Builder in Arc GIS 9.3 software. The process defined in this paper uses from runoff capacity for decision and some information such as runoff potential map, distances from residential areas map, irrigated cultivation map and rain-fed cultivation map is inputting in the system. With combination of these maps makes the rain water harvesting prone areas map. The result shows that more than 40 present is in medium class and 32 present is in good class.

Mucoid cysts tibiofibular joint top (TFS) is a rare cause of nerve compression at the knee. We report the observation of a soldier of 46 years, who presented with painful swelling sitting at the top of the anterolateral aspect of the left leg third with peroneal neuralgia, lasting for four months. Clinical examination revealed an oval mass, deep, sensitive, poorly demarcated sitting on top of the anterolateral compartment of the right leg third. Ultrasound and magnetic resonance imaging (MRI) of the knee revealed an intramuscular myxoid cyst Depond joint superior tibiofibular. Electromyogram (EMG) was in favor of an invasion of the superficial peroneal nerve. A biopsy excision of the lesion was performed. Pathological examination confirmed the diagnosis of a mucoid cyst. The evolution is marked by the complete disappearance of pain, recovery of normal sensitivity and lack of recurrence after a year of decline.

This paper discusses the effectiveness of strategies used by rural municipalities in recovering service consumer debts. The choice of Thulamela municipality was informed by increases in municipal service consumer debts as a result of inadequate collection of rates and taxes. Unemployment, lack of enforcement of debt and credit policy issues was among the challenges for the municipality. A municipal service consumer debt recovery survey approach was used to unpack the challenges. The municipality uses an ad hoc debt recovery process instead of a holistic approach. The study outlines lessons to be learnt from the Thulamela experience for decision makers at local municipal level.

Ions concentration of seventeen wheat cultivars (Triticum aestivum L.) in NaCl salinity (16 dS m-1 and two weeks exposure) was assessed to evaluate the ability of these traits in salt screening. There was an increase in Na+ concentration and decrease in K+ concentration in salinity stress compared to control condition in shoot parts. Even thought, there was a clear relation between salt tolerance or salt sensitivity and Na+ concentration in shoot plant. It seems that the increase in concentration of Na+ concentration can be criteria to distinct salt tolerance in the shoot of early wheat plant. Therefore Na exclusion measurement can be applied with other trait such as yield and yield components to screen wheat cultivars in salinity condition.

The reaction between 5-(4-phenyl carbonyl methyl amino) 8-hydroxyquinoline(PHQ) and melic anhydride afforded heteronuclear bisligand namely 4-(4-(2-(8-hydroxyquinolin-5-ylamino)acetyl)phenylamino)-4-oxobut-2-enoic acid(CMHQ). The bisligand was designated as CMHQ and its co-ordination polymers with Cu+2, Zn+2, Co+2, Mn+2and Ni+2 metal ions were prepared. The co-ordination polymers and parent ligand were characterized by elemental analysis, IR, NMR spectral studies, thermogravimetry, number-average molecular weights ( ), diffuse reflectance spectral studies and magnetic susceptibilities. All co-ordination polymers and parent ligand were also monitored for microbicidal activity.

Double-diffusive natural convection in a square cavity is numerically analyzed using velocity-vorticity form of Navier-Stokes equations. The governing equations consist of vorticity transport equation, velocity Poisson equations, energy and solutal concentration equations. Galerkin’s weighted residual finite element method is employed to solve the coupled governing equations through isoparametric formulation. Numerical predictions of vorticity, velocities, temperature and solutal concentration are computed using an iterative algorithm in order to resolve the coupling between the governing equations. The capability of the velocity-vorticity formulation is demonstrated by a detailed study on the variation of Nusselt and Sherwood numbers for a wide range of the characteristic parameters.  Our simulation results show that at high Lewis number, the average Nusselt number decreases and the average Sherwood number increases with increase in buoyancy ratio. 

The numerical studies are performed to examine the Micropolar fluid flow past an infinite vertical plate. Finite difference technique is used as a tool for the numerical approach. The micropolar fluid behaviour on two- dimensional unsteady flow have been considered and its nonsimilar solution have been obtained. Nonsimilar equations of the corresponding momentum, angular momentum and continuity equations are derived by employing the usual transformation. The dimensionless nonsimilar equations for momentum, angular momentum and continuity equations are solved numerically by finite difference technique. The effects on the velocity, micro rotation and the spin gradient viscosity of the various important parameters entering into the problem separately are discussed with the help of graphs.
