A global concern for a transition to a sustainable construction approach is imminent and highly important. This research aims to identify a justifiable strategy to improve sustainable constructionsuccess. To enhance the success rate of sustainability, important factors contributing to the cause such as project management, integrated approaches, and modern methods of construction (MMC) are studied. The core ideology is to understand the relational attributes of these factors, their significance, and the mediating effect of modern methods of construction (MMC) in sustainable project success. A deductive research approach is undertaken, by performing a web-based self-administered quantitative questionnaire survey with 5-point Likert scale. The survey adopts the snowball purposive sampling technique to collect data from construction professionals like project managers, architects, contractors, researchers, etc. The survey recorded a total of 149 responses, majorly from the UK, forming the base for several statistical data analysis techniques, supporting the formulation of research findings. Structural equation modeling is the cardinal analysis approach carried out to draw relational values between the principal research factors. The findings of the research highlight that both project management and integrated approaches display a significant positive relationship with sustainable construction project success. It is observed that project management and integrated approaches have positive impact on sustainable construction success with R = 0.208 and R = 0.569 respectively, at a significance value <0.05. Moreover, incorporating modern methods of construction as the mediating factor further enhances the project success rate. Thus, it can be depicted that in order to gain a maximum output from project management and integrated approaches to build the sustainable construction the role of modern methods of construction is critical. The research will help to bridge the gap between available extensive knowledge on sustainable construction and scant information on its successful implementation.

Background: Asia is the global epicenter of the coronavirus disease 2019 (COVID-19) pandemic; however, COVID-19–related mortality in Asia remains lower than in other parts of the world. It is uncertain whether the mortality of COVID-19-infected kidney transplant recipients (KTXs) from Asia follows the lower mortality trends of the younger Asian population. Methods: Specific transplant centers from countries in the Asian Society of Transplantation were invited to participate in a study to examine the epidemiology, clinical features, natural history, and outcomes of COVID-19 infections in KTXs. Data were analyzed and compared with those of large cohort studies from other countries. Results: The study population was 87 KTXs from nine hospitals in seven Asian countries. Within the study population, 9% were aged 60 years and older, and 79% had at least one comorbidity. The majority of patients (69%) presented with mild-to-moderate COVID-19 severity. Disease progression was more frequently encountered among those with moderate or severe infection (23%) and non-survivors (55%). The mortality rate was 23% (n=20) and differed according to the level of care: 12% (n=1/8), 15% (n=10/67), and 100% (n=9/9) of patients managed as outpatients, in the general ward, and in the intensive care unit, respectively. Disease severity at the time of presentation was an independent predictor of mortality. Compared with the mortality rates in other studies worldwide, mortality rates in the current study were comparable. Conclusions: Mortality in Asian KTXs who were infected with COVID-19 remains high and could be related to comorbidity burden and the constraints of the general healthcare system when the COVID-19 caseload is high.

Transplantation in Asia during the coronavirus disease-19 (COVID-19) pandemic: briefs from member countries of the Asian Society of Transplantation

The coronavirus disease-19 (COVID-19) pandemic has affected 1,029,968 people in Asia as of May 16, 2020. Although Asia was the first continent to be affected, many countries in the region continue to battle COVID-19, which challenges the way transplant programs provide their services. Given the diversity of healthcare systems in Asia, the countermeasures in response to COVID-19 are as potentially diverse. This review reports the experiences of transplant services in member countries of the Asian Society of Transplantation (AST) as well as provides a platform for sharing of best practices during the COVID-19 pandemic. AST invited member countries to provide a short description of their transplant experiences during the COVID-19 pandemic. Whenever information is available, countries were asked to provide information on COVID-19 related statistics, status of transplant programs, mitigation measures taken to prevent COVID-19, and other areas of transplant programs impacted by COVID-19. Ten countries responded to the invitation of which seven still have active transplant programs at varying levels of activity. All countries have protocols for donor/recipient screening and countermeasures to prevent COVID-19 infections in recipients and healthcare providers. Interestingly, these countries report only 16 transplant recipients with COVID-19 infection but no cases of donor-transmitted COVID-19 infection. Despite the diversity of healthcare systems in Asia, transplant centers in Asia have taken appropriate precautions to avoid COVID-19 infections, though the long-term impact of COVID-19 remains unclear.

A tumor immune interaction is a main topic of interest in the last couple of decades because majority of human population suffered by tumor, formed by the abnormal growth of cells and is continuously interacted with the immune system. Because of its wide range of applications, many researchers have modeled this tumor immune interaction in the form of ordinary, delay and fractional order differential equations as the majority of biological models have a long range temporal memory. So in the present work, tumor immune interaction in fractional form provides an excellent tool for the description of memory and hereditary properties of inter and intra cells. So the interaction between effector-cells, tumor cells and interleukin-2 (IL-2) are modeled by using the definition of Caputo fractional order derivative that provides the system with long-time memory and gives extra degree of freedom. Moreover, in order to achieve more efficient computational results of fractional-order system, a discretization process is performed to obtain its discrete counterpart. Furthermore, existence and local stability of fixed points are investigated for discrete model. Moreover, it is proved that two types of bifurcations such as Neimark-Sacker and flip bifurcations are studied. Finally, numerical examples are presented to support our analytical results.

The study of cell components has been an active area of research since the last few decades. Cytoskeleton of the cell which gives shape and provides structure to the cell has three main components, microtubules, microfilaments and intermediate filaments. Each of the cytoskeletal components is surrounded by various filamentous or the other cytoskeletal components act as a surface layer on these filaments. The stability of these components affected when cell perform various functions in the body and as a result these filaments buckle, vibrate and bend. In the present study the buckling behavior of microfilament is discussed with the effects of surface by using Euler Bernoulli beam theory and the obtained results for free and surrounded microfilament are shown in the tables and figures.
