Revealing the quasiparticle electronic and excitonic nature in cubic, tetragonal, and hexagonal phases of FAPbI3
No full textThe development of three-dimensional (3D) hybrid organic-inorganic perovskites has sparked much interest because of their rich light-harvesting capabilities in solar cells. However, the understanding of the electronic and optical properties, particularly the excitonic shifts upon structural phase transition with temperature in these materials, is not fully clear. Here, we report the accurate description of electronic and optical properties of mostly studied FAPbI(3) across the cubic-tetragonal-hexagonal phases, using the relativistic GW method and Bethe-Salpeter Equation (BSE), including the spin-orbit coupling effects. Our GW calculations reveal that the bandgap values vary from 1.47 to 3.54 eV from the room temperature cubic phase to the low temperature hexagonal phase. Our optical analysis shows that excitonic peaks are blue-shifted, and exciton binding energies estimated by the model BSE approach increase from 74 to 567 meV going from the cubic to hexagonal phases. Our results may have important impacts on the practical uptake of hybrid perovskite based solar cells under different climatic conditions. (c) 2022 Author(s).

CONSUMER AGE INFLUENCE ON FOOD LABEL READING HABIT
No full textThe objective of this paper was to detect the food label reading habit of consumer according to consumer age. To achieve this goal author of this paper has adopted five variables with independent and dependent status. Four variables were independent like reading complete food label, reading manufacturing date, reading expire date and reading ingredients. One variable was dependent like influence on purchase behavior. The data was collected through questionnaire and 350 questions were distributed among customers. Author has received 251 valid questions. The data was divided into two groups. The two groups were designed with respect to age range. In (Group I) the respondent’s age ranges was 20-25 and mean age was 23. Whereas in (Group II) the age was 26-30 and average age was 27. Correlation and regression test were conducted and results has unfolded the fact that there is a difference in both groups for food label reading habits. In Group I three variables significantly influence on purchase behavior of consumer while purchasing food items like reading manufacturing date, reading expire date and reading ingredients. In Group II only two variables like reading ingredients and reading manufacturing date has significant effect on purchase behavior of consumer while purchasing food products. Two variables were common in both groups like reading manufacturing date and reading ingredients. This result has also depicted that consumer normally, irrespective of age group; focus on manufacturing date, which give the freshness of food product, and ingredients to know the nutrients used in processing the food
Student satisfaction level among allied health sciences students at King Edward Medical University
No full textThe purpose of this study was to evaluate student satisfaction with their program, academic environment and administrative services in terms of its effectiveness on their professional attitudes, lives and career. A total of 261 students of allied health sciences program at King Edward Medical University, were examined in terms of personal satisfaction by means of a specifically designed student satisfaction survey. A qualitative analysis approach was used to interpret the data generated by a three‐part survey form circulated to the four proceeding sessions of allied health sciences program and satisfaction of students in 12 major disciplines was evaluated. The data was entered in statistical product and service solutions (SPSS) version 22 using quantitative variables and descriptive statistics including frequency distribution tables and diagrams. The study revealed a student satisfaction of only 22.1% with their program with different levels of recommendation in different sub-disciplines. A total of 20.9% students agreed to the library facilities, 53.9% with computer lab, 35% with administrative support, 29.6% with sports facilities and 49% with teaching methodologies. The present study concludes that most of the students had little satisfaction concerning their field of study. So, it is necessary to make an attempt for continuous development of quality services
Differentiating Asthma from its mimics
No full textAll that wheezes is not asthma this adage accredited to Chevalier Jackson emphasizes the importance of differentiating asthma from its mimics, particularly if the patient is not responding to usual therapy. The above statement also warrants further diagnostic evaluation and management of non-asthma conditions that mimic asthma. We present here a case of a middle aged female who presented with severe bronchospasm, initially labeled as asthma but was resistant to usual anti-asthma therapy. After further workup she was eventually diagnosed to have esophageal achalasia
