Relatively few studies in foreign language testing have been conducted on differences between males and females' performance on various sub-tests of the Iranian National University Entrance Exam (INUEE). The present study seeks to explore gender effect on correlation in various sub-tests of the INUEE. To explore correlation coefficient for a group of 1000 students who participated in INUEE, Pearson Product Moment Correlation Coefficient formula was employed. The outcomes of a statistical analysis denoted that there is a distinction between the functions of different sub-tests of the INUEE for female and male test-takers.

This paper presents an experimental investigation on the influence of cutting parameters of wire cut Electrical Discharge Machining (Wire-EDM) during the machining of Inconel825.Demand for better surface finish has been increasing recently for super alloys. The low rigidity and high material removal rate of Inconel alloys offers a challenging task in obtaining a better surface finish. The analysis of surface characteristics like surface roughness of Inconel-825 is carried out and an excellent machined finish can be obtained by setting the machining parameters at optimum level. Experimentation has been done by using Taguchi’s L18 (21x37) orthogonal array under different conditions of parameters. The response of surface roughness is considered for improving the machining efficiency. Optimal combinations of parameters were obtained by this method. The confirmation experiment shows, the significant improvement in surface finish (1.36µm) was obtained. Multiple linear regression model have been developed relating the process parameters and machining performance indicates the suitability of the proposed model in predicting surface roughness. The regression analysis are used to predict the error between actual and regression values of surface roughness in Wire EDM process. Experimental results demonstrate that the machining model is suitable and the Taguchi’s method satisfies the practical requirements.

One of the main challenges in organizations acting in a dynamic and complicated environment is doubtlessly agile supply chain based on which they have to be able to answer to customers quickly. But agile supply chain is influenced by different agents. Using the model based on agent, this study has tried to simulate the agile supply chain in a High Education Institute. There are three impressive elements are used in this model called as: smooth, offender and fault case those are also categorized in two groups impressive and impressible. There is a model is designed by using NETLOGO software which examines the impression and impressibility on each other. After executing the model at the case studied university at point of Time-769, the organization’s improvement will be possible in the best estate. All offender elements are reduced at this point.

Agriculture is the most beautiful and easy profession in the world; yet marked by drudgery and exploitations. It is a beauty to behold nature: plants, animals, insects, air, water, soil, rock, food, medicine, drugs. It is prestigious and honourable to have food on the table: morning, afternoon and evening. It is very appetizing to have various food stuff and ingredients. Food is always delicious if not abused. A well fed man is a happy man. A hungry man is an angry and sad man. Food! Food! Food everywhere; yet they are unavailable and unaffordable. Something must be wrong: with ourselves or how we embrace agriculture. But nothing is wrong with agriculture; except where we checkmate and abuse nature, in the name of agricultural revolution and increased food production. This paper reviews agriculture in peril. Happy reading.

Differential Power Analysis (DPA) has been shown to be an effective attack in cryptographic systems capable of revealing secret data by measuring power consumption. Recent DPA resistant circuits / logics incur severe penalties in terms of area and power. This paper proposes the design of a secure logic family for DPA resistant cryptographic devices. Here the power consumption is insensitive to unbalanced load conditions thus adopting a semi-custom design flow without any constraint on the routing of the complementary wires. The proposed logic is based on a novel encoding concept where the information is represented in time domain rather than in the spatial domain as in standard dual-rail logic. In this paper, a logic family exploiting the proposed concept is simulated to show power consumption independent of the processed data and routing capacitances. It also shows an optimistic improvement in the energy consumption balancing and area reduction.

AbAnbaar, lake, pool have been made to provide drinking water supply in Iran and other countries. However access to water was not same, but all of them have one thing in common, the storage of water. Haj KazemAbAnbaar was located in Maghlovak district which have made in Ghajar dynasty. This structure are include reservoir, stairway, Pa Shir, Sar Dar (portal) and two Bad gir (Windward). Reservoir capacity is 1870 m3and rectangle shape, which build from east to west. Tall portal have eight meter height and decorated with Maegheli (Islamic calligraohy). Date analysis has been indicated that excavation and construction of this AbAnbaar was done by Rikhtai method (pouredi.e made of poured lime-plaster) and while digging out, its ceiling was constructed. The construction material used for abanbars were, slaked lime mortar,Saruj ( the type of plaster most commonly used called sarujm is a compound from six part clay, four parts lime, one part ash), stone, wood and AjorAbAnbaari( special bricks for construction of cistern). The roof of the reservoir has constructed barrel-vault and roof of the stairway constructed with two incrustration and Taghahang (kind of vault). This building have SaghaKhane and Moazeneh(on top of the portal there is a place which called Moazeneh). This study has been taken by data libraryand conducting field studies of AbAnbaar plan with triangulation method and technology of construction.

For decades the issue of pregnancy has been thought of as a woman's domain. For this reason, some expectant men not only show little concern but engage in illicit sexual activities or affairs. The study aimed at investigating the sexual behaviors among expectant fathers in urban areas and it focused on the sex seeking behaviors among the same group; the factors influencing the expectant fathers’ engaging in affairs during their wives’ pregnancies as well as the consequences of the said sexual behaviors. A total of 136 expectant fathers or men participated in the study. The study adopted the descriptive and exploratory research design. Data was collected using a questionnaire and was analyzed using the chi-square statistic and presented using frequencies and percentages. The study found out that age, religion and employment status of the respondents had no effect on the respondent’s participation in sexual activities when their wives were expecting.

This research conducted in the Institute of Technical / Mosul / Plant Production Department, using the method of analysis of spatial and temporal of the lands covered by the desertification in the province of Nineveh, which were Baaj, Al-Hadar, Telapta and Al-Shemal region . Was reached through a study that desertification is a form of degradation which affects lands in arid and semi-arid regions such as Iraq, including Nineveh province, under the influence of natural factors ( environmental ) which is not suitable , such as climate factors , which include high temperature , atmospheric drought, low rate of relative humidity, intensity and direction of the wind in summer season , the high value of evaporation , drought of soil , low rates fall Raining in winter , the intensification of solar radiation ,high temperature, great warming disparity between winter and summer and between day and night , changes in atmospheric pressure , addition to the lack of water surfaces , drought of valleys . Thus these factors combined caused the demolition of the soil profile, the soil structure and the cohesion of the particles due to the demise of organic matter which associated the soil particles were represented by humus material, which leads to a decline in the productivity of the land and the impact on food security. Either human factors , they include in mainly form environmental pollution due to excessive exhaust of natural resources , loss of the phenomenon of the natural balance and self-renewal in the biosphere , not rationalize the consumption due to population increase , expansion of human activities , not applying the clean technology , increasing the use of polluted traditional energies , which produced the polluted matter as solid, liquid and gaseous which caused an imbalance in the ecosystem which is global warming, as well as the misuse of the land environmentally and mechanically in the cultivated operations of soil and crop with the following traditional irrigation methods which caused the increase of soil salinity also overgrazing non alternately, methods of deforestation , which forest is green belt , windbreaks to dust and sand storms . As a result of the interaction of environmental with human factors that the reaction is reflected in the form of the ecological imbalance called desertification. Through spatial analysis was evaluated the quality of desertification in the region the situation from medium to severe because the soil is still present despite the deterioration of soil fertility , loss of vegetation , low productivity but requires processed quickly otherwise become an a environmental disaster , because the speed of desertification in the region between 5-10 km / year , through the spatial analysis of desertification can be classified ; Baaj in first place Al-Hadar second place , Telapta third place and the Al-Shemal aspect region fourth place, where areas are represented above 20 %, an area of 1,385,843 dunum from total area of farmland on the level of province . This is clearly evident from the survey and spatial analysis, which caused the displacement, harmed (30000) human, in Baaj 134 village and (70) of the village population in others. The destruction of 75% of the livestock in addition to loss of biodiversity and degradation of soil and vegetation cover. Through the temporal analysis for areas covered by desertification can be seen that the time series between 1941-1985 was rainfall at; 338 ml / year. Can be conclude that during the 44 years the rate of precipitation is not suitable for the needs of agriculture , particularly crops of wheat , barley and natural grassland except with implemental irrigation , which did not witnessing the areas above then the phenomenon of desertification , where continued Londoner rates fall of rain water that reached 130 mm / year for the period of time confined between 1996 to 2000 where not harvested winter cereal crops , between 2002-2012 were the rainfall vibrant, through(11) years reached as average 303,7 ml/ y and the year 2013 increased the rainfall to 472,9 ml/ y ,through the past years increased temperatures rates , increased heat waves, hot days in summer as well as the irregular distribution rainfall , increased frequency of droughts ,increased their intensity in the region , was the very severe of drought in 2008 reached severity -2.48 by techniques of standard precipitation index (SPI) also increased sandstorms in terms of repetition and intensity reached 32 storm , as well as sintering heaven 71 days of dust thick , were critical stage in the water requirement for cereal crops in 2001 , either increased evaporation value in the year 2000 is the highest ,average of relative humidity 52% for years2002-2012,the falling dust was 13gm/m2/month in 2012 and suspended dust in atmosphere as average 1,394 microgram/m3, this was highest rate by comparison with Baghdad &Basrah proninces.The result of non-stability of environmental status and vibrant raining through past years, where decreased groundwater recharge and their levels, also increased their salinity and degraded the quality . The negative impact of climate factors within the time series reflected negatively on soil and deteriorated their physical, chemical, and biological properties, causing desertification which negative reflected on winter farming production and vegetation cover.

A second order partial differential equation occurring frequently in applied mathematics is the wave equation. A generalization of this equation inevitably arises in many mathematical analyses of phenomena involving the propagation of waves in continuous media. Here, we applied the wave differential equation to investigate and explain neural communication using the nervous system. On application of Bloch nuclear magnetic resonance theory, a linear 1-dimensional homogeneous second order partial differential equation, as a model, is obtained which represents a nerve set in a vibrational motion. Analytical results from the solution of the differential equation show that the transmission of nerve impulses is not a flow of electrons, as in the case of electric current, but a wave of electrical activity travelling along the neurone. A three dimensional pictoral representation of the results further explains the phenomenon clearly.
