Interdiscursivity in Pakistani Drama Serials: A Study of Critical Discourse Analysis
No full textThe purpose of this study is to analyse the interdiscursivity of Pakistani dramas by applying critical discourse analysis to them. This article explores the nature, function, and use of interdiscursivity in four different Pakistani dramas. Baandi by Asma Nabeel, Cheekh by Zanjabeel Asim Shah, Baghi by Shazia Khan, Ab daikh Khuda Kia Karta hai by Syed Amer Ali Shah Husaini. This paper also deals with the strategies of language and how language is being practised by different characters in different dramas to show their cultural background through the lens of media. Fairclaugh's dimensional model has been used to analyse the data. The study also takes into account how interdiscursivity explores the hidden agenda behind these ideologies. This study aims to dig out scenes and characters from these four dramas. Discursive practises have been shown through the perspective of violence and hegemony created by the continuous practise of patriarchy in our society.

Previous studies in the literature showed that the learning and clinical training of students can be enhanced by using VR and AR in the field of dentistry education. Also, VR and AR technologies are reported to be useful in dentistry education that can improve students' learning and clinical training by providing a more interactive and engaging learning experience that improves comprehension and preservation of knowledge. Using VR/AR-based technologies in dental education is found to be more effective than traditional education methods. Accordingly, the main aim of this study is to understand the recent trends for the applications of VR/AR and simulation environments in the field of dentistry. Firstly, a literature review is conducted with 57 articles considering the last 10 years (2012-2022) to provide a general overview of the VR/AR tools, and simulations in dental education which can guide instructional system designers to better use the technology- enhanced learning environments in the field. Additionally, to obtain a more comprehensive understanding of the application and educational perspective specific to dentistry, one of the widely utilized topic modeling algorithm, Latent Dirichlet Allocation (LDA), was applied to analyze 669 articles extracted from the SCOPUS database. By combining these methodologies and results, this research provides valuable insights into the current state and potential future directions of incorporating VR/AR and simulations in dental education
Impact of Physical Stress on Gate Dielectric in Ultrathin Si Gate-Stack for Next-Generation Flexible CMOS Technology
No full textIn this article, we report the fabrication and characterizations of sub-20-μm thin flexible Si die containing active devices. Thermally grown 2.62-nm silicon dioxide (SiO2), atomic layer deposition (ALD)-deposited 3-nm HfO2 (high-κ), and 10-nm TiN layers are used to fabricate an array of MOSCAPs on Si wafers. The fabricated devices are characterized to analyze the doping density (Na), flat-band voltage (Vfb), threshold voltage (Vth), fixed oxide charge (Qf), and interface trap densities (Dit). Then, a deep reactive ion etching (DRIE) reduces the die thickness to ~15μm for flexibility. The encapsulated flexible devices are found to have relatively better breakdown performances when tested in compressive stressing and no variations when in tensile stress. The time-dependent dielectric breakdown (TDDB) measurement shows a minimal variation in flexible and bulk devices. The TDDB and a voltage acceleration slope are projected in flexible devices after performing a 10 000 times bending and relaxation process (cycling).The authors would like to thank Erica Alvarez Conde, Florencio Pisig Jr., Ahad Syed, and Dr. Syed Kazmi of the King Abdullah University of Science and Technology (KAUST) nanofabrication cleanroom facility for their constant support
Derangement in Serum Inflammatory Biomarkers Among Patients with End Stage Renal Disease
No full textBackground: End stage renal disease is an important public health problem. Renal replacement therapy, dialysis and transplantation are used to provide relief from the symptoms of end stage renal disease whilst also preserving the life of the patients though they are not curative. Haemodialysis is the widely used method although it produces a negative impact on quality of life of the patients. Hypoalbumianemia has been reported to be frequently present in haemodialysis patients and correlates strongly with mortality and morbidity. Objective: To determine the frequency of deranged inflammatory biomarkers in patients with end stage renal disease on hemodialysis, in Nishtar Hospital Multan. Material and methods: One hundred thirty-one cases with ESRD were selected from Hemodialysis Department, Nishtar Hospital Multan and 3ml of venous blood sample was taken before starting a session of hemodialysis and sent to central laboratory of Nishtar Hospital Multan. Serum Albumin was obtained by an automatic analyzer, and serum CRP by slide test, free of cost, to measure deranged inflammatory biomarkers. Data was analyzed by using SPSS version 20. Results: Of these 131 study cases, 85 (64.9%) were male patients while 46 (35.1%) were female patients. Mean age of our study cases was 42.37 ± 5.98 years. Of these 131 patients with ESRD on hemodialysis 33 (25.2%) were diabetic, 65 (49.6%) were hypertensives and 13 (9.9%) were obese. Mean duration on hemodialysis was 19.51 ± 7.59 months, 80 (61.1%) had to undergo hemodialysis twice a week and 51 (38.9%) had to undergo three times a week. Mean serum albumin level was noted to be 3.37 ± 0.59 g/dl. Mean serum C-reactive protein level was noted to be 20.73 ± 15.84 mg/l. Frequency of deranged inflammatory biomarkers in our study was noted to be in 109 (83.2%) of the study cases. Conclusion: Very high frequency of derangement in inflammatory biomarkers have been noted in our study. This derangement in these inflammatory biomarkers was significantly associated with female gender, increasing age, increased duration on hemodialysis and increased frequency of hemodialysis. The early diagnosis of these derangements followed by preventive measures can help decrease disease morbidity and mortality among targeted population. Keywords: Inflammatory biomarkers, deranged, end-stage renal disease, hemodialysis
Optimization of Viscosity Modifier in Lubricants Manufacturing
No full textViscosity modifier is one of the key ingredients of lubricant as it serves the purpose of controlling undesired viscosity of the lube with respect to temperature. Viscosity modifier helps lube to develop desired film thickness around the contact parts of the machine to protect in high temperature conditions. It also plays a vital role in maintaining the desired pumping viscosity requirements in cold conditions. Since viscosity modifier is one of the common ingredients of lubricant that serves the purpose of controlling the undesired viscosity changes with respect to temperature, the standardization of the viscosity modifier shall contribute, without compromising the lube quality, to minimize the sourcing challenges and providing optimized cost benefit in formulations and warehousing space
ادب کی تفہیم: ردِتشکیل کے تناظر میں
No full textUnderstanding literature relates to the interpretation of a literary text in a specific perspective. The critical appreciation, analysis and establishing an opinion about the text are some of the important tools to understand a literary piece of work. For this purpose, a complete understanding of literary as well as critical theory is indispensible to move forward. There are various perspectives to understand literature, which may be divided into four major categories; these are Author oriented, Context oriented, Reader oriented and Text oriented. This paper presents the debates of understanding literature in the context of Deconstruction; a theory presented by Jacques Derrida. The main idea of this theory is to unveil those meanings of the text, which have not been revealed on the surface. A limited work is available in the field of Urdu Applied Criticism with special reference to Deconstruction; because this analytical approach has been ignored. This theory may be applied to understand literature with the help of discourse analysis, narratology, linguistic analysis and textual criticism.
Investigating how Financial Investments are being directed toward Social Impact Projects, such as Education, Healthcare, and Poverty Alleviation
No full textThis study looks into the factors that influence the allocation of financial investments in social impact projects, specifically in education, healthcare, and poverty alleviation sectors. As social investments become more important in addressing global challenges, understanding how financial resources are directed toward these critical sectors is essential for fostering sustainable development. A quantitative method was used, and financial data obtained from various countries were collected to analyze the relationship that exists between investment levels and these key economic, political, and governance-related factors. Descriptive statistics, correlation analysis, and regression analysis were carried out using SPSS to identify the determinants of investment in these sectors. The results suggest that the variables that are significantly influential are economic factors, such as GDP, policy incentives, institutional capacity, and political stability. Descriptive statistics revealed the highest investment to be healthcare, followed by education and poverty alleviation, whereas correlation analysis shows a strong positive relationship between GDP and levels of investment in all the sectors. Regression analysis confirmed that policy incentives and FDI were some of the strong predictors for investment in healthcare, but institutional capacity was the crucial determinant for education. The study sustains the hypotheses that these investments are positively correlated to economic development, vary differently between public and private sector allocation, and are also governed by the expected returns from investment. The study concludes with policy recommendations to optimize investment strategies, including the promotion of public-private partnerships, the development of metrics for Social Return on Investment (SROI), and strengthening institutional frameworks. It also suggests areas for future research, especially in the exploration of long-term impacts of social impact investments and cross-country comparisons
Surgical Grand Rounds at a university hospital: creating researchers out of surgical training programs
No full textObjective: To evaluate the outcome of Surgical Grand Round (SGR) presentation at a University Hospital; in terms of national, international presentations and publications.
Introduction: Grand rounds are an important educational activity in all teaching hospitals however each institute has its own way of conducting them. At our institute, grand rounds in the Department of Surgery include an original research presentation by the residents with a faculty supervisor. The publication of the research work acts as a measure of its success. In this study we analyzed the outcome of this activity and review the factors affecting the publication.
Methodology: It is a retrospective review of prospectively maintained data of all presentations made at the Surgical Grand Round at a University Hospital during January 2001 and December 2010. Presentations with incomplete follow up records were excluded from analysis. A Publication-Presentation Index (PPI) was used to evaluate outcomes of SGRs and to study factors influencing outcomes and differences in PPI in each category were calculated using the chi square test.
Results: Total of 470 presentations were made. Majority presented retrospective studies (73%). Majority of the presentations were made by junior residents (year 1-3, 62%). Following presentation, 279 (59.4%) studies were presented at a national conference, 80 (17%) were presented at an international forum while only 99 (21.1%) studies were published. Mean presentation to publication time was 34.8 months. Study design, level of resident, section of surgery, sample size and national/international presentation were associated with conversion to a publication (all p \u3c0.05). Overall PPI was 0.32. Randomized controlled trials had the highest PPI (0.67).
Conclusion: The PPI has a potential to be used as a tool to study the association of presentation to publication. This model of Surgical grand rounds can be used to enhance research among residents and to create a researcher’s mind from a surgical training program
