Lead sulphide (PbS) thin films have been deposited on glass slide substartes by chemical bath deposition technique from an aqueous alkaline bath containing lead nitrate [Pb(NO3)2]and thiourea [SC(NH2)2]. The influence of bath temperature on the properties of the films were investigated . The structural, surface morphological and optical properties of films were studied by X-Ray diffraction, scanning electron microscopy and UV-Vis spectroscopy, respectively. The X-Ray diffraction studies reveal that the PbS films were polycrystalline in nature with preferrential orientation along (200) plane. The scanning electron microscopy results indicate that the films were smooth, uniform and adherent to the substrate. The band gap energy was decreased from 1.2 eV to 0.9 eV as the bath temperature was increased from 30 OC to 60 OC. The films deposited at 60 ^OC have shown good crystallinity and uniformly distributed over the surface of substrate with larger grain sizes. Therefore, the optimum bath temperature is 60 ^OC.

Plants are utilized as therapeutic agents since time immemorial in both organized (Ayurveda, Unani) and unorganized (folk, tribal, native) form. The ethanolic fruit extract of Cucumis trigonus Roxb of family Cucurbitaceae was used to treat the urolithiasis induced by ethylene glycol. On this course, the extract also repairs the changes that happened in the biochemical parameters urea, uric acid and creatinine in serum and urine of the urolithiatic rats. The ethanol extract (150 mg / kg b.w.) reduced the levels of elevated biochemical parameters in serum and urine significantly (p<0.05) when compared with the toxic groups. The results shown by the ethanol extract (150 mg / kg b.w.) was compared to standard thiazide drug treated group showing no significant difference (p<0.05) and thus exhibited potent antiurolithiatic activity.

Oxovanadium(IV) and Dioxouranium(VI) complexes of Schiff bases derived from 3-substituted-4-animo-5-mercapto-1,2,4-triazole and glyoxal/biacetyl /benzyl have been synthesized and characterized on the basis of analytical and spectroscopic studies. The elemental analysis agrees well with the 1:1 stoichiometry of the type VO.L.So4 and UO2.L.(CH3COO)2 respectively. The IR data suggests that, ligands have coordinated to the metal ion through azomethine nitrogen atoms in a bidentate fashion by keeping sulphur atom of mercapto groups away from coordination. Thermograimetric measurements and XRD pattern have also been done on some oxovanadium (IV) complexes. Some of the VO(IV) and UO2(IV) complexes have been screened for their antimicrobial and antifungal activity. One of the VO(IV) complex has been evaluated for its oxytocic and antihistaminic activity.

The purpose of this study is to assess the influences of perceived justice with service recovery on recovery satisfaction and word of mouth, and to examine the mediating role of recovery satisfaction in the relationship between perceived justice and word of mouth intention. Data were gathered on perceived justice with service recovery, recovery satisfaction and word of mouth by means of survey from management undergraduate students, who experienced failure within last one year in a university in Iran. The results show that distributive and procedural justices have a significant and positive relationship with recovery satisfaction. However, there was no significant relationship between interactional justice and recovery satisfaction. The results also found that recovery satisfaction has a positive relationship with word of mouth. Moreover, the results of this study confirmed that recovery satisfaction mediates the relationship between perceived justice with service recovery and word of mouth in all perceived justice dimensions except for distributive justice. Managerial implications of these findings are briefly discussed.

The following experimental procedures were carried out on the samples using standard analytical methods: fat, fatty acids, phytosterols and phospholipids analyses, quality assurance determination and the calculation of uncertainty interval percentage (UIP) were undertaken. Statistical evaluations were: linear correlation coefficient (rxy), coefficient of determination (rxy2), linear regression coefficient (Rxy), coefficient of alienation (CA) and index of forecasting efficiency (IFE). The results were: crude fat range (g/100 g): 47.6 (cooked seeds) – 49.6 (roasted seeds) followed by calculated fatty acid of 45.5-47.4; SFA range (% total fat): 19.0-23.4; MUFA, 54.8-57.9; DUFA, 20.1-23.5; TUFA, 0.50-1.70; total unsaturated fatty acid (TUFA) was raw seeds (81.0 %) > roasted seeds (79.9 %) > cooked seeds (76.6 %); PUFA range was 21.8-24.1 %; PUFA/SFA was 0.93-1.21; 2n-6.3n-3 range was 13.7-43.6. Among the phospholipids, lecithin was highest among the samples with values of 725-1168 mg/100 g or 36.0-57.2 %. Among the phytosterols, sitosterol was highest in each sample with a range of 81.1-111 mg/100 g. Significant relationship existed among the following parameters at r = 0.01: fatty acids level for raw seeds/roasted seeds (Rs/Rt.s), raw/cooked seeds (Rs/Cs) and Rt.s/Cs; energy contribution by the fatty acids fraction: Rs/Rt.s, Rs/Cs and Rt.s /Cs as well as in phytosterols level.

Students’ satisfaction has become an essence of success in today’s highly competitive world. In service industry specifically the education industry, communication is vital to determine students’ satisfaction. Past researches indicated that, most meaning of conversational messages comes from non-verbal communication. Therefore, this study intended to examine the relationship of non-verbal communication cues to students’ satisfaction. A total of 300 respondents were sampled from all around UiTM Kedah. They were evaluated on their perception on lecturers’ non-verbal communication behavior that would lead to their satisfaction to the services provided. The results of the study illustrate that three of the non-verbal communication cues were significant and positively related to students’ satisfaction. Kinesics and paralanguage was rated as among the non-verbal communication cues that provided the most impact on students’ satisfaction. However the result also indicated that there was no significant relationship between physical appearances of the lecturers to the students’ satisfaction. Overall, students’ in UiTM Kedah are fairly satisfied with the non-verbal communication cues of the lecturers. The present study caters for a wide spectrum of students and development professionals, especially those who are interested in non-verbal communication related issues. It is highly hoped that the information gleaned from the present study may assist all service employees specifically in understanding better, the importance of non-verbal communication and its effects on students’ satisfaction.

The young student’s community of every society and all part of the world is aspiring to get the degree. But everyone is not the same as one another, each one is differed in getting degree as the result of what they wish to become in their life. In this context the College or University plays major role for providing/ offering degrees depends on the society’s need. The government’s role on the part of youths is to provide Education, Economy, Employment, formation of culture and utilizing manpower to nation. The colleges which has got sophisticated and produces the good result then it’s attracted many students. The same not much facility, poor quality of teaching and poor results of examinations is less attractive. Sometimes parent’s interest plays an important role for choosing degree of a candidate. The African country of Zambia has taken for the study area as one of the researchers is belonging to the study area. The sample of 10 higher secondary schools students (Grade 12 level) were taken for this study using stratified random sampling method. The questionnaire was converted into numerical data state in order to analyze the student’s interest in acquiring degree. The students were analysed with reference to location of student, type of institution. The data was analyzed by using SPSS software. The appropriate results were drawn and suggestions made to improve their perception on acquiring degree.

The handloom industry in Andhra Pradesh is famous for its age old weaving craft next to agriculture. Located in Andhra Pradesh Prakasham district, Chirala mandal is famous for its specialized weaving craft. Considering entire district of Prakasham 95% of total textile production comes from Chirala mandal alone stretching from Eepurupalem - Vetapalem - Pandilla palli, a stretch of 16 Kms length. In Chirala mandal itself some 300 varieties of fabrics were produced. Some of the world famous Tie and Die products are taken birth in Chirala. Chirala is known as second Mumbai. However it is observed that this traditional cottage industry is losing its attractive occupational status forcing the weavers to migrate to other occupations out of desperation. In the year 2007 around 15,000 weaver families have already migrated to other occupations, but even of course the weaver families are still continuing to hope for a bright future on day or the other. The income from these highly skilled weaver products are not able to produce an honorable living by solely depending upon this occupation resulting in migration to other occupations. The present study is under taken to understand the grievances of the weavers and also the weavers shifted to other professions.

Human beings use language both to communicate with others and to monitor their internal thoughts. Harley (2001) mentions that "in some form or another, language so dominates our social and cognitive activity that it would be difficult to imagine what life would be without it". The complexity of language has led to a wide range of methods to study such a kind of phenomenon. The study of relationship between language and thought has often been examined using cross-cultural studies of languages. Language affects much of our lives and covers a wide variety of topic areas, such as speech, writing, reading, etc. Language seems to have some effects on our perception of others. There are also great differences in the use of any one language within a culture, and the way we speak reflects our cultural and social backgrounds. The social and cultural aspects of language include social class, ethnic background and gender. The role of gender on the way how people think and behave is the main focus of the present study which will be discussed in detail.
