    The aim of this study is to investigate the feasibility of extracting of natural rubber protein, named hevein; represented by its amino acid, cysteine (L-cystine) by using aqueous two phase system (AlPS) of polyethylene glycol of molecular weight 6000 (PEG 6000) and sodium chloride. AlPS has been proposed as an alternative method as it preserved biological activity, nontoxic, and cost-effective. Purification and extraction by using polyethylene glycol/salt AlPS is very suitable since he vein can tolerate very well with inorganic solvent. Feasibility of AlPS of PEG 6000 with sodium chloride is studied where the phase diagram is developed. A precise composition of PEG 6000 with sodium chloride from the binodal curve is mixed to form two phases system to study the partitioning behavior of L-cystine where the concentration of each component and L-cystine on both phases will be analyzed. The partition behavior is recorded with respect to PEG 6000 and N aCl concentration. The highest percentage recovery of L-cystine is observed

    Amidst intense competition, manufacturers are constantly striving to improve their competence with others. In this respect, aesthetics of the product has become one of the prime factors in capturing market share. On the other hand, ever increasing pressure from the public, customers and governments has forced manufacturers to take environmental considerations very seriously. This study focuses on the development of an intelligent computer-aided design system in order to assist designers to design specifically on the basis of aesthetic and environmental considerations. The study began with an extensive literature survey. It was found that small volume of research work had been done in the topic of design for aesthetics whereas a substantial volume of research had been ongoing in the field of design for environmental considerations. Although the aspect of combination of these two factors of design was not fully investigated. So the project was understood to be a novel one. To achieve the objectives of the research, two research surveys were conducted to gauge public viewpoint about the aesthetical attributes of the bottles of several consunler products. The first survey was conducted among Dublin City University (DCU)'s students and staff, and the second one among the residents of Dublin city and its suburb. The information obtained from these two surveys was used in the development of the design system. The design system consists of overall score & aesthetics advisor, simple material selection for bottles index, simple life cycle analysis and golden section ruler modules. The author created threshold values for the first three modules that work as benchmarks to judge the design in terms of aesthetics and environmental considerations. This novel approach of design and the software tool developed will be helpful aids to the designers to consider aesthetics and environmental aspects of design at the primary stage leading to faster product development and savings of money

    The purpose of the research is to use the technologies to shift the emphasis from teaching to learning. The ultimate goal of Web-based e-Learning is to bring the learning to the learners, not to bring the learners’ to learning. The teaching-learning phenomena of developed countries have changed from Brick to Click approaches (e-Learning). However, Web-based e-Learning is still new paradigm in developing countries like Bangladesh. Web-based e-Learning is absent in technical and vocational education and training (TVET) system. TVET in Bangladesh is depriving from the benefit of Web-based e-Leaning. Thus, the aims of the research are to illustrate the residence with mode of internet use and internet services with level of education; to explore the current literacy rate (%) by different economic classes in rural and urban areas; to identify the physical facilities of TVET classrooms; and to assess the infrastructural conditions of TVET institutions for providing the suggestions to Web-based e-Learning integration in Bangladesh. The researchers have visited 45 TVET institutions and observed 210 live classrooms in Bangladesh. The infrastructural conditions of 30 TVET institutions in urban areas were also observed with the structured questionnaires to get the results for applying the concept of Web-based e-Learning integration. The expected outcomes of the research are, once the e-Learning system can be introduced in TVET in developing countries like Bangladesh, there will be a breakthrough in the education system. More students will be enrolled, outreach will go further, better learning material will ensure quality output, ICT based technology will be adopted in the process of and finally bring an integrated benefit to the society.   Keywords: Web-based e-Learning, TVET, Literacy rate and Socio-economic development

    Get PDF
    Purpose of Study: The aim of this study is to influence the global leadership behaviors on performance in multinational companies. The leadership of multinational companies has become a prominent issue in the 21st century. Organizational performance depends on the leadership style and behavior of the organization. It is also viewed as the survival and profitability of an organization in which its measurement is primary both in manufacturing and services. On the other hand, transactional leadership focuses mainly on goal attainment and transactional leaders are focused on task completion and have fewer emphasis on the emotions and challenges of subordinates or employees. Methodology: The data for this study were obtained from existing literatures on the impact of global leadership behaviors on the performance of multinational companies. The methodology heavily relied on existing previous literatures on the subject being dealt with. Results: Transactional leadership was explicated as the style of leadership that focuses on meeting specific goals or performance criteria and the development of followers and their needs. Relations-oriented leaders are different from task-oriented leaders. On this side of the spectrum, relations-oriented leaders tend to focus more on developing a close relationship with their employees. Implications: Transactional leadership style lacks supervision and influence on subordinates from leaders, as they indulge themselves from any situation that threatens or confronts them; therefore, the responsibilities are shifted on the employees

    The COVID19 pandemic, a unique and devastating respiratory disease outbreak, has affected global populations as the disease spreads rapidly. Recent Deep Learning breakthroughs may improve COVID19 prediction and forecasting as a tool of precise and fast detection, however, current methods are still being examined to achieve higher accuracy and precision. This study analyzed the collection contained 8055 CT image samples, 5427 of which were COVID cases and 2628 non COVID. The 9544 Xray samples included 4044 COVID patients and 5500 non COVID cases. The most accurate models are MobileNet V3 (97.872 percent), DenseNet201 (97.567 percent), and GoogleNet Inception V1 (97.643 percent). High accuracy indicates that these models can make many accurate predictions, as well as others, are also high for MobileNetV3 and DenseNet201. An extensive evaluation using accuracy, precision, and recall allows a comprehensive comparison to improve predictive models by combining loss optimization with scalable batch normalization in this study. Our analysis shows that these tactics improve model performance and resilience for advancing COVID19 prediction and detection and shows how Deep Learning can improve disease handling. The methods we suggest would strengthen healthcare systems, policymakers, and researchers to make educated decisions to reduce COVID19 and other contagious diseases.

    Objective. We studied the clinicopathological parameters of adenocarcinoma arising from endocervix (ECA) and from endometrium (EMA) based on the expression of P16ink4a, P21waf1, and p27Kip1 proteins. Study Design. Immunohistochemistry was done on sections of confirmed ECA and EMA from hysterectomy specimens which have had no prior chemotherapy/radiotherapy. Results. There were 40 ECAs and 92 EMAs. The mean age of ECA was 49.82 (SD 10.29); the youngest was 30 years old and the oldest 75 years old. The mean age of EMA was 54.45 (SD 10.92); the youngest was 30 years old and the oldest was 82 years old. For ECA, the size of the tumour is significantly associated with age and with depth of infiltration. FIGO stage is associated with histological grade. p21WAF1 expression is significantly associated with infiltration of the corpus and lymph node metastasis. p27Kip1 expression is significantly associated with lymph node invasion. The presence of lymph node metastasis is strongly associated when p16INK4a and p27Kip1 expressions are analyzed in combination. For EMA, p16INK4a expression is associated with histologic grade. Conclusion. Our study shows that we could use these cell cycle markers as predictors for more aggressive subsets of adenocarcinoma of the cervix and endometrium
