The main objective of the present study was to investigate the relationship between Isfahan University male and female graduates’ unemployment with their emotional/mental health. The population of the study includes all the BA graduates from Isfahan University of whom 100 have been randomly selected. Of the sample population twenty five female and twenty five male graduates who had enrolled in the Department of Labor and Social Affairs in Isfahan and twenty five working male graduates and twenty five female ones were randomly selected that comprised the other fifty individuals of the sample. The General Health Questionnaire (GHQ) specifically touching upon the mental and emotional traits and characteristics of people was used to collect the data and the findings of the research having been analyzed indicated that there is a significant difference between the emotional/mental health level of the employed graduates and that of the unemployed ones and between the emotional/mental health levels of female and male ones.

Knowledge management is a process that helps organizations to find important information, select, organize and publish them; and it’s a proficiency that will be necessary for actions like solving problems, dynamic learning, decision making. Knowledge management can improve a wide range of organization performance properties by enabling company to more intelligent performance, but it’s not enough alone; because knowledge management to be useful needs undertaking staff to organization and their job, that accept the knowledge management process with spirit and heart and perform it(Wiig, 1999:14). With considering the importance of this topic, the current discussion will study the relation between knowledge management and professional commitment of staff at a petroleum company in the south of Iran. Formation of this study was based on this question that with considering the importance of professional commitment and organizational commitment of staff, what the relation between knowledge management and professional commitment and organizational commitment of staff is. The tools of data collection in order to knowledge management evaluation is the 21 questions questionnaire of Proset et al., to evaluation of professional commitment and organizational commitment, that’s combination and native 27 questions questionnaire of Allen and Meyer et al.; the stability of professional commitment and organizational commitment obtained 83% and the stability of knowledge management evaluation was 0.87 and because of being Kronbakh alpha of questionnaires both more than 0.7, both questionnaires had obligatory stability. To determine being normal, the data obtained of Colmogroph -Smirnoph was applied and confirmed the results of being normal test. Hypothesizes of the study were examined by performing of Spearman correlation test and their significant and positive effects were proved, this means that knowledge management totally has a direct and significant relation with organizational commitment and professional commitment.

This article deals with the role of religion of Islam in tourism industry. In this respect it studies the relationship between Islam and tourism, aspects of the interconnection between Islam and tourism, manners of Muslims as hosts and guests, and finally the international collaboration in Islamic tourism industry. The study showed the religion of Islam has had profound influences in destination conditions and inbound and outbound tourists and has been influential in determining the content, direction and implementation of tourism policy.

Otoacoustic emissions (OAEs) are an important, non-invasive method for early hearing screening that objectively assesses cochlea characteristics. Their usage, specifically brief-evoked OAEs (TEOAEs), enables the accurate diagnosis of hearing abnormalities in infants and early children, frequently before behavioral indications appear. OAEs are fast, cost-effective, and appropriate for a variety of screening settings, including neonatal intensive care units and school programs. Introducing OAEs into infant hearing screening procedures contributes to faster prediction and management, eventually improving the developmental prospects to kids with hearing loss.

For all structural/functional application, tribological properties of material play most prominent role in day to day life. Tribology arises when there is relative motion between two surfaces in contact results loss of mass from surface by rubbing. To restrict this type of wear suitable lubricant can be use. This paper describes about wear behavior of three composites specimen made from constituting elements: alumina oxide, titanium dioxide and copper with the help of pin on disc machine. These three specimen pellets are made by powder metallurgy technique by increasing the furnace temperature from 1000C to 7000C with a rate of 30C/min. From wear test, wear rate graphs are plotted with respect to sliding velocity. In this study it is found that, composition of composites and sliding velocity majorly impart on wear rate. Our present aim is to test the mixture of various compositions of alumina and titanium in a copper base and test it for its different properties, to compare it with pure alumina. Among three composite it is observed that more the amount of TiO2 percentage, lesser is the wear rate. This investigation can help to improve the tribological properties of surfaces by varying their composition.

A two-dimensional laminar unsteady MHD free convective heat and mass transfer flow past a vertical porous plate immersed in a porous medium has been studied numerically in presence of chemical reaction, heat generation and variable suction. The governing partial differential equations are reduced to a system of self-similar equations using the similarity transformations. The resultant equations are then solved numerically using the Runge-Kutta method along with shooting technique. The effects of governing physical parameters on velocity, temperature and concentration as well as skin-friction coefficient, Nusselt number and Sherwood number are computed and presented in graphical and tabular forms. Comparisons with previously published work are performed and the results are found to be in excellent agreement.

Aneurysmal bone cyst (ABC) is a benign cystic lesion of bone composed of blood-filled spaces separated by connective tissue septa. it usually affects the metaphyseal in long bone (70-90%) and then vertebrae (15% of cases) Talus is an infrequent site of ABC and may be confused with other benign bone tumors because of its behavior less aggressive and his prognosis more favorable than the classical proximal lesions. The curettage with or without bone graft showed a high success rate to treat ABC of the talus cryosurgery for a recurrent lesion and talectomy as the last resort in some cases.

Central nervous system cavernomas are usually supra tentorial. Cerebellar localization is rare. Imaging, especially MRI can detect these malformations and look for other associated vascular malformations. If cavernous angioma is associated with a developmental venous anomaly, the venous anomaly should be spared due to the considerable risk of venous infarction following the abolition of cerebral venous drainage. We report the case of a 39 year-old man presenting with chronic headaches indicating brain MRI which showed cerebellar cavernoma associated to developmental venous anomaly.

Present study was focused on intake of duckweed by chicks and to evaluate the growth performance and carcass characteristics of chicks. A total number of 106 chicks were allocated to 3 treatments with 3 replicates. The treatments were categorized into group A (25% duckweed and 75% commercial feed), group B (50% duckweed and 50% commercial feed) and group C (100% commercial feed). Results showed that crude protein was higher in group B followed by group A while in group C crude protein was lower but total feed intake, average weight, live weight, meat and bone weight, skin weight, head weight, liver weight, intestine weight and shank weight were higher as compared to group A and group B and this was due to the fluffy nature of duckweed and small size of crop. It was concluded that sewage grown duckweed can be successfully utilized as poultry feed. Chicks can survive on duckweed and farmer can save money. This is the first study in Pakistan.

The goal objective of this study is to propose a new double ARA transform (DARAT). We employ this transform to prove the convolution, existence and other relevant theorems as well as derivatives properties. Subsequently, this transform is applied to solve some illustrative integral- differential equations. This approach was shown to be a powerful and efficient means to tack integral- differential equations.
