The results of this research are also useful for early-career librarians, faculty members, and researchers to understand online search techniques and successfully retrieve the required information for research and educational tasks

Isolation of Caffeine from Carbonated Beverages

The work presented on the isolation of naturally occurring alkaloid from carbonated beverages. The extensive presence of caffeine in different plants plays an important role in the long-standing acceptance of caffeine-containing products. Caffeine (3,7-dihydro-1, 3,7-trimethyl-1H-purine-2,6-dione or 1,3,7-trimethylxanthine) is an alkaloid belongs to Methylxanthine family. Liquid-liquid extraction methods were used in the assay of research work. Chloroform was taken as extracting solvent. Solid residue of caffeine was recrystallized from 95% ethanol using 5ml/gram (5ml per gram). It is declared to raise caffeine, effects a number of different drugs include Paracetamol, Benzodiazepines and Aspirin and amount of plasma free Fatty acids increases. While inform that in regular sleeping interaction caffeine take place and raise the absorption of certain drugs. Changes in drug metabolizing enzymes, acts as an agent in a microsomal system of the body. The highest amount of caffeine dry crystal is extracted in sting sample while the 7up sample is free from caffeine

Tracing Institutional Role of Technical and Vocational Education and Training Skills for Socio-Economic Development of Women in Baluchistan

This paper describes socio-economic and demographic impacts of TVET provision for women empowerment in rural and urban areas of Baluchistan. Different economic factors and demographic attributes are examined with TVET programs on empirical counts for policy analysis. The analysis is descriptive and questionnaire based data from 178 TVET qualified women by using three stage stratified sampling technique are traced out in rural and urban areas of Baluchistan.The factors like, self-employed status of women, parents’ education, ethnicity, household head characteristics, rural and urban set ups, institutional affiliation, and self-choice for a specific TVET trade contribute to socio-economic and demographic empowerment of women. Rural women are found to get less economic benefits of jobs and income earnings as compared to urban counterparts.The tentative findings suggest for socio-economic and demographic impacts of TVET for women to support to the consensus of development for TVET contributions into human capital theory. The findings guide towards the profound contribution of TVET in theory of human capital formation and its socio-economic and demographic impacts specifically to women empowerment studies in the un-developed regions

Comparison of Dexmedetomidine with Midazolam during Monitored Care Anesthesia (MAC) in Patients Undergoing Septoplasty

Objective: To compare the sedative and analgesic outcomes of dexmedetomidine with midazolam for monitored anesthesia care (MAC) in patients undergoing Septoplasty. Methodology:  This comparative study was conducted at Shalamar Medical and Dental College Lahore from March 2019 to August 2020. A total of 150 patients who were planned for Septoplasty under MAC having age 18-45 years, and ASA status I-II in Shalamar Medical and Dental College Lahore. Patients were randomly divided into two equal groups; In group D; IV dexmedetomidine 1 µg.Kg-1 was given over five mins after that IV infusion at the rate of 0.5 µg.Kg-1.hour-1 was started. In group M; midazolam 0.06 mg.Kg-1 was given as slow bolus after that continuous infusion at the rate of 0.01 mg.Kg-1.hour-1 was started. Sedation was monitored according to Ramsay sedation scale and VAS scale was used to measure the intensity of pain. Results: The Mean age was 34.3±5.7 years in group D versus 35.7±6.1 years in group M. There were 49 (65.3%) male patients in group D and 47 (62.7%) in group M. Mean sedation and pain score was significantly less in group D as compared to group M (p-value 0.001 & 0.002 respectively). There were 12 (16.0%) patients in group D who required rescue sedation and 32 (42.7%) in group M required rescue sedation (p-value 0.003). There were 14 (18.7%) patients in group D who required rescue analgesia versus 29 (38.7%) in group M (p-value 0.006). Conclusion: Use of dexmedetomidine for MAC is advantageous as compared to midazolam in-terms of better sedation and analgesia and reduced requirements of rescue doses of sedatives and analgesics

Perceptions of Research Students about Information Resources of Digital Library and Difficulties faced during usage

The basic aim of this study was to examine the perception of research students about the importance of online sources of information in digital libraries and the problems faced by research students while consulting online information resources in digital libraries. To achieve these goals, a quantitative research method was used. A self-administered questionnaire was developed and used for data collection. The population of the study has consisted of research students studying in M. Phil and Ph.D. in the Faculty of Behavioral & Social Sciences and Pure Sciences. Data was collected from 278 respondents and analyzed by using SPSS software. Results showed that respondents were aware of different online information resources and had positive perceptions regarding online information resources. They possessed satisfactory searching skills. They have obtained training sessions to use online information resources. They preferred digital form, print form, and electronic form to receive information. Respondents pointed out problems in using online information resources. These problems include information overload on the web, subscription issues, infrastructure problems, load shedding issues, etc. They demanded training to increase online searching skills. The study concluded that research students studying at the University of Punjab have a good level of searching skills. It was recommended that librarians working at the University of Punjab should offer adequate training programs to assist the research students in searching for online information

OBJECTIVE: functional outcome of improvement after decompression for dorsal spine tuberculosis in terms of frankle grading. METHODOLOGY: This prospective study was conducted after ethical approval at neurosurgical ward mmc/mti through non-probability sampling. Clinical and radiological examined patients with carriers of dorsal spine tuberculosis were enrolled in study. After surgery they were followed for three months and improvement were measured comparing pre and post op Frankle grading. RESULTS:  Total of 38 patients underwent surgical procedure decompression ± fusion through postero-lat approach (costotransversectomy) in which 42% were male and 58% were female. Mean age was 34±5. Distribution for age group was 18-30(08), 31-40(13), and 51-60 (06). Level of disease D4-D8 were 17(44.8%), D9-D12 were 21(55.2%). CONCLUSION: decompression and stabilization in spine tuberculosis is safe, effective and results in good outcome clinically. The advantages of surgery include through debridement, decompression and achievement of spinal stabilization. KEY WORDS: Dorsal spine tuberculosis, corpectomy with fusion, laminectomy, outcome measure
