This study shows the ‘Anchorperson Presentational style of private TV channels and students perception university of Sargodha”. In Pakistan electronic media is considered more powerful media for all types of communications. Especially private electronic media is playing very important role in both positive and negative aspects. The contents of private media are considered as perception and opinion making tools. Talk shows and their anchorpersons are considered influenced in opinion and perception making of respondents. For this study 50 respondents have been selected from BS and 50 respondents from Master Class. In this study survey research technique was been used to exposure the role of anchorpersons and their presentational style in talk shows. The empirical research shows the anchorpersons has political affiliation as well as exaggerates the issues. Findings show that Geo news anchorperson Hamid Mir exaggerate the issues (59%) as compare to JavedChaudry (55%) and Kamran Shahid (42%). It is also find that that Hamid Mir is considered most political affiliated anchorpersons which is supported by findings taht Hamid Mir anchorperson of private TV new channels has political affiliation frequently (71%) which is much more JavedChadury (55%) and Kamran Shahid (50%).It is also find that viewers are more satisfied with anchorpersons of Express News as compare to other news channels. Over all findings show that respondents are satisfied (59%) from anchor persons of Express News which is much more Geo News (51%) and Duyna (40%).

Acute ischemic stroke is a major cause of long-term disability and the second leading cause of mortality worldwide. One of main parts of it pathogenesis is production of reactive oxygen species. The goal of this study was to evaluate the neuroprotective effect of the new xanthine derivative B-YR-2 (hydrazide of 1,3-dimethyl-8-N-benzylaminoxanthinyl-7-acetic acid), which demonstrated high antioxidant qualities in vitro, in comparison with thiotriazoline, mexidol and citicoline.. Injection of B-YR-2 compound to the rats with experimental stroke had the most pronounced neuroprotective effect. B-YR-2 increased number of glial cells and neurons in the cerebral cortex and stimulated their morphofunctional activity.

Success is a disputed concept which is difficult to exactly define and quote. This study is related to Software Engineering field in which success factors and perception of key stakeholders (i.e. top management, core team and clients etc.) about software project success is tried to identify. Study postulates that there are so many dimensions which are behind of a successful software project. Success has different meanings and varies according projects to projects in Software Engineering industry. It is due to conflict in determination and selection of success factors among stakeholders. Software project stakeholders may differ based on their organizational culture and related goals, current market structure and their customized needs satisfaction (as a client or end user) from intended use of software. Qualitative technique has been applied by using thematic analysis on articles between the time frame of 1991-2010 with major three keywords of “software project success”, “project success” and “perception of stakeholders”. Study provides better understanding why there is a divergent view of success which stakeholders of a software project perceives and must need to know.

According to Smith and Nelson in World Englishes (Kachru, 2006:450) and Matsuura (2007), intelligibility, comprehensibility and interpretability are different concepts which are used interchangeably. Intelligibility refers to word or utterance recognition while comprehensibility refers to meaning and interpretability refers to discoursal level—pragmatics, issues which are interwoven in attitudinal aspect of leaning. This paper is an overview of the previous intelligibility article examining the intelligibility of eight different Englishes, USA, UK, Farsi, French, Korean, Chinese, Turkish, and Russian, to two groups of Iranian students—with Turkish and Farsi as their native language. Concluding on the findings of that paper and comparing the case with intelligibility in different levels of education from high-school—aged 14—to university students—aged 20 above, the researcher came to the conclusion the Iranian students need to be aware of the world Englishes and think not of British or American Englishes as the only form of English. Nevertheless, students’ being aware of the speakers’ nationality may change his attitude toward the person, an issue which necessitates further research.

In this paper we describe some recent developments that have taken place in still image compression. We addresses about different compression techniques and also give a performance comparison. Functionality and principles of compression algorithms are discussed in a unified manner. This survey reviews more recent articles on image compression and discuss their role in current research directions. There are several image compression algorithms some of them are lossy and some of them are lossless. Thus medical image, pre press industry, art work, remote sensing images for lossless image compression.

The purpose of the study was to prepare spherical agglomerates (SA) of Tolfenamic acid (TA) by solvent change method. Crystallization medium used for spherical agglomerates of Tolfenamic acid consisted of N,N-dimethylformamide (DMF), Water and chloroform. The presence of solvents residuals in SA was determined by Gas chromatography and particles were characterized by DSC, FT-IR, XRD and SEM. The respective solubility study and dissolution behavior studies were carried out. The samples were stored in stability chamber to investigate their physical stabilities. Residual Solvents in SAs were found to be within the limit and exhibited decreased crystallinity as well solubility and dissolution of the spherical agglomerates was improved than commercial sample of Tolfenamic acid. In stability study, it was found that physical properties and release profile of the spherical agglomeration was unaffected for 6 months. Hence this technique can be used to obtain modified drug raw material for formulation of tablets of Tolfenamic acid by direct compression with directly compressible tablet excipients.

Soil and water contamination by endosulfan, an organochlorine pesticide was experimented in lysimeters in 2010 and 2011. These lysimeters were filled in with alfisol brought from Korokoro watershed (60.6 km2, Mali), a small agricultural one where cotton and cereals are the main crops. In the present experimentation, cotton was grown in lysimeters and treated with endosulfan which is frequently used in cotton production by some farmers although its agriculture use has been banned worldwide. After rainfall events subsequent to endosulfan application on cotton, runoff and infiltration were always sampled. Similarly, after each rainy season, composite soil samples were also collected in each lysimeter box. In 2010, soil samples were collected in surface horizon (0-20 cm) and depth one (20-40 cm) but in 2011, they were sampled in the whole soil profile about 1 m. Soils were analyzed by gas chromatography associated to a mass spectrometer at UMR Metis, Université Pierre et Marie Curie (France) but water ones were analyzed at University of Bamako (Mali). The results showed that soil and water are contaminated by endosufan residues. Water contamination was mostly explained by runoff events in 2010 than 2011 ones (6.5 ± 2.9% against 0.1± 0.09% of exported matters) but infiltration events in 2010 were low than those of 2011 (0.1 ± 0.09% against 0.2± 0.04% of exported matters). However, in 2010 and 2011, endosulfan residues were more stocked in soil surface horizons (22 ± 15% and 43.6 ± 12.6%) than depth ones (3 ± 1.4% and from 15.3 ± 17.5% to 28.5 ± 24.8%).

My article explores the predicament of the marginalized women in the major plays of Tennessee Williams- one of the most prolific American dramatists of the 20th century. In his three major plays- “The Glass menagerie’, “A streetcar named desire” and “Summer and Smoke” we witness the women who live with a sense of despair- trapped and displaced by the patriarchal norms of the American society. Though Williams does not openly champion the rights of the woman in his plays, he however strongly empathizes with their marginalized existence in the contemporary society. They are portrayed as helpless figures, who have no control over their destinies and are alienated in their social circles. Blanche, Stella, Amanda, Laura and Alma are delicate and sensitive women who struggle their best to adjust with the society- but in the long run are misunderstood, rejected and victimized in the male-dominated American society. They inhabit a world of men, who are indifferent to their needs and to their womanhood. Each of these women loses her place in the world governed by the male characters. The pathos of Blanche, Laura, Amanda and Amanda is that they refuse to acknowledge their state of passivity and continue to struggle for their dignity and social standing even when the battle seems lost.

This study endeavors to investigate if assessment tools such as TKT, DELTA, and the alternative assessment have any statistically significant washback effects on the reflection of Iranian EFL in- service teachers. To fulfill the requirements of the study, the researchers selected 90 subjects and categorized them into three groups. Three assessment packages which included the actual samples of TKT, DELTA, and alternative assessment tools, along with the instructional and coaching materials related to all these modes of assessment, were randomly presented to the three groups respectively. The researchers adopted a pre-test post-test comparison group design to investigate the washback effect of each assessment tool and compare the three groups in terms of teacher reflection. Having used one-way ANOVA to analyze the collected data, the researchers concluded that the alternative assessment tools, compared to DELTA and TKT, had the strongest washback effect on teachers' reflection.

Undoped and Mn doped lead sulfide (PbS) thin films were grown on glass substrate by Successive Ionic Layer Adsorption and Reaction deposition method. Mn content in aqueous solution was varied by adding 0.1, 0.25 and 0.5 mol of manganese chloride. The structural, surface morphological, optical properties and magnetic properties of the films were studied by X-ray diffraction, scanning electron microscopy, UV-Vis spectroscopy, Atomic force microscopy and Vibrating Sample Magnetometer respectively. The X – Ray diffraction studies reveal that the Mn doped PbS thin films were polycrystalline in nature with preferential orientation along (2 0 0) plane. The scanning electron microscopy results indicate that the films were uniform. The bandgap energy of PbS and Mn doped PbS thin films are 2.4 eV and 3.1 eV. The Atomic Force Microscope results indicate that the films are uniform and adherent to the substrate. The VSM studies reveal that the thin film exhibit multi domain behavior.
