Tribal areas in the district of Nagaur were visited to collect informations on ethnomedicinal plants used by local people, Vendors, Ojha, Bhopa, Bhagat, Vaidyas and Sadhus. The preset investigation in aimed to create awareness about the ethnomedicinal value of the plants and their uses to draw the attention of pharmacologists, phyto chemists and pharmaceutical.

Previous tests on PVC-concrete composite columns showed that most of tested columns had failure regions near the top or bottom of the columns. Therefore it is intended, in this study, to reinforce the ends of these columns in an attempt to improve their behavior. A series of unreinforced and partially reinforced PVC-concrete composite columns were tested under axial compressive loading. It was found that the strength of partially reinforced PVC-concrete composite column is greater than that of corresponding unreinforced column by about 3%, and that the ultimate strain of partially reinforced PVC-concrete composite column is less than that of corresponding unreinforced column by about 4.4%. Although the increase in strength was unnoticeable, the steel reinforcement at the ends was adequate to prevent failure to occur at these ends.

In recent days most of the automotive parts are manufactured with different materials which will increase the weight of the vehicle and the materials also cannot be recycled. But with the European union and Asian countries stringent norms on automotive end life i.e the parts should be recycled. This made the researchers to use natural fibers in composite materials. With their low cost, low density, stiffness, high specific strength and biodegradable characteristics, they are considered as perfect replacement for conventional fibers. This has resulted in creation of more awareness about the use of natural fibers based materials mainly composites. The properties of the composites mainly depend on the interfacial adhesion between the matrix and the fibers. The present study aims at the mechanical properties namely tensile strength, flexural strength and impact strength of the composites. In the present work the composite is produced with good compressive strength (Egg shell) and tensile strength (coconut coir) materials and is further tested for various mechanical properties. The results indicated that these composites are very good for automotive applications.

This research has cautiously reviewed past studies on Meta cognitive strategies encompassing on planning, monitoring and evaluating learners. The basic purpose of these reviews was to identify strategies to assist children in enhancing their reading and understanding potential. On basis of those reviews seven well defined strategies were formulated for the teachers to apply in a group of 8-9 years old learners for developing reading comprehension by an experiemnt.Study indicates that if proper strategies applied during reading sessions, positive change in the learners is significant. This study is helpful for readers specially teachers to consider cognitive and metacognitive strategies as a mean to plan their reading lessons on vocabulary building, making connections, questioning, summarizing, predicting, visualizing and monitoring. Therefore, it is recommended that these strategies be incorporated for teaching English reading lessons.

Iran, nowadays, is in dire need of entrepreneurs like never before. Entrepreneurs are the people who use their investments to produce new products or provide services to the public that eventually boost up the level of service to the community, employment and capital assets to avoid stagnation in the economy, which means improvement in the public welfare. The role of the university, as an organization with the tasks of education and training, is very important. Entrepreneurship is a new phenomenon that has played an important role in the economy of developing countries. Entrepreneurship has a key role in the competitive economy based on the current market situations. In this study, the entrepreneurs’ capabilities of entrepreneurship (success-seeking, tendency to take risk, tendency to creativity, internal and external control and independence) have been evaluated and the influence of them in operating a business has been analyzed. The survey method and the questionnaires were used to collect data for this research. Participants in this study were selected from undergraduate students in Islamic Azad University of Tafresh, Iran. The stratified sampling has been used in sampling design and the total number of 220 questionnaires were distributed among the students. The results showed that the scores of entrepreneurial capabilities in students seeking success, tendency to creativity and locus of control were found to be above average and, on the other hand, tendency to take risks and independence were below average.

The study was designed to identify various factors which affect the job satisfaction of the public sector university teachers. Population of the study comprised of all teachers teaching at the public sector universities of Islamabad. A stratified random sample of 100 male and female teachers was collected from 3 leading universities of Islamabad through a 35 items research questionnaire with six dimensions. Collected data was analyzed through SPSS, results revealed that overall university teachers are satisfied with opportunities of advancement in their profession, satisfied with their management and coworker, but they are unsatisfied with workload, physical work environment and with their present pay structure. Analysis of demographics depicted that female teachers are satisfied with their job as compared to male teachers. Younger university teachers have higher job satisfaction as compared to older ones whereas married teachers are less satisfied with their salaries and unmarried are less satisfied with physical work environment.

One of the key issues in management today is the lack of Job Involvement in employees. This lack ultimately leads to lack of Performance in employees. The study was conducted to see the impact of Job Involvement on the Job Performance and the difference between the females and males with respect to Job Performance. The data was collected using questionnaires. The respondents were mainly from the Banking sector of Pakistan. The results show that there is a positive correlation (r=0.705, p<0.01) between Job Involvement and Job Performance. Moreover, the results for group statistics show there is no significant difference between performance of males and females (µm=48.6744, µf=47.2432) at confidence Levels of almost 35%. The reasons for such results are then discussed.

In this paper, finite element model for flow of a viscous lubricant in a slider bearing is considered as a problem. For this problem, two different types of finite element models have been presented which are the velocity-pressure finite element model, with (u,v,P) as the primary nodal degrees of freedom and the penalty finite element model with (u,v) as the primary nodal degrees of freedom. Quadrilateral elements are used since they are more reliable for pressure as well as for velocity fields in the penalty finite element model.

Most ocular diseases are treated with topical application of eye drops. After instillation of an eye drop, typically less than 5% of the applied drug penetrates the cornea and reaches intraocular tissues, while a major fraction of the instilled dose is absorbed and enters the systemic circulation. As ocular efficiency of topically applied drugs is influenced by the corneal contact time, most common method of improving ocular availability of drugs is to increase pre-corneal residence time by using vesicular system and hydrogel. One such approach to improve bioavailability of drug is the use of in-situ gelling system, which gets converted from sol-to-gel as a result of change in pH. By using Carbopol940 – a pH sensitive gelling agent, an attempt was made to develop niosomal in-situ gelling systems of Norfloxacin, a fluoroquinolone antibiotic; useful in the treatment of bacterial conjunctivitis, to increase the ocular residence time of drug. HPMC K15M was incorporated as viscosity enhancing agent. The promising formulations M1, M2, M3 and M4 were evaluated for pH, drug content, in vitro gelation, in vitro drug release, in vivo drug release, viscosity and stability. Percent drug content of 82.5%, 86.7%, 85.3% and 90.8%; viscosity of 320cP, 405cP, 440cP and 500cP at 100 rotation per minute (RPM), cumulative percent release of 37.9%, 47.7%, 48.2% and 49.7%, was observed for formulation M1, M2, M3 and M4 respectively. The developed formulations were therapeutically efficacious, stable, non-irritant and provided sustained release of the drug for 12 hours.

Microalgae are considered to be the world’s future energy reservoir and various aspects have been followed for optimizing the algae growth for large scale production of biodiesel. For the same, selection and screening of microalgae strain for its lipid productivity is much more important. Fourier transform infrared (FTIR) spectroscopy was used in this study for the analysis of lipid extract from natural isolate of Chlorella vulgaris. In order to evaluate the strain productivity the reference strain was obtained. Both the cultures were grown in a chemically-defined media under photoautotrophic culture conditions. Lipid extraction procedures were standardized for both strains based on Fourier transform infrared (FTIR) spectroscopy .The extracted lipid samples were analyzed. This study reveals that the natural isolate identified as Chlorella vulgaris strain is suitable for further optimization procedures and found with high percentage of residual lipid proportions. Also the results show that FTIR technique can be applied for determination of single cell biomass composition from phytoplankton communities.
