Net zero energy building design methodologies include integrative approaches and numerical tools to provide optimal performance and cost-effective results. Team integration, characterized by knowledge transfer between disciplines, has yet to be quantified for the design processes of these buildings. This article proposes a specific methodology for designing net zero energy buildings, tested through a case study design process conducted in an academic setting at Universidad Centroamericana in El Salvador, with the p [...]

Fischer-Tropsch reactors operated in a steady state suffer from a low pore effectiveness factor and a high methane selectivity caused by internal mass transfer limitations due to the accumulation of long-chain hydrocarbons inside the catalyst pores. Therefore, an alternating process switching between Fischer-Tropsch synthesis (FTS) and drainage of the pores by hydrogenolysis is proposed. The periodical cracking of the accumulated waxes within the (partially) filled pores, realized by a switch from syngas (H2, CO) t [...]

This research aims to know the effect of the Rotor Radius Ratio on the performance of the hybrid Vertical Axis Wind Turbine Savonius-Darrieus NREL S809 model using the Computational Fluid Dynamics method. Two-bladed Savonius is used as an internal rotor, and three-bladed Darrieus NREL S809 as an external rotor. Turbine model performance is analyzed through the value of the Moment Coefficient and Power Coefficient. The result shows that the increase in the Rotor Radius Ratio value causes an increase in the initial M [...]

Wastewater generated by the textile industry has been a major environmental concern for a long. Production of fiber involves various steps and uses a lot of chemicals, dyes, and water. Therefore, the effluent produced from the textile industry needs proper purification before discharging into the water body. The current review summarizes various physical and chemical methods like ion exchange, coagulation-flocculation, membrane separation, membrane distillation, oxidation, ozonation, etc., for wastewater treatment.

The World Health Organization attracted more attention to the positive effects of physical activity (PA) and the adverse effects of stress on the health of older people and, therefore, attracted a more significant number of practitioners. To verify the impact of PA on stress in older people. Observational and analytical research, composed of 690 older people of both genders residing in Brazil, present in street races (as participants or observers), who volunteered to respond to the research protocol consisting of s [...]

While there is abundant literature on the benefits of Mindfulness-Based Interventions (MBI), data about factors associated with their Efficiency are scarce. Our study attempts to determine the moderators of efficacy and adherence in Mindfulness-Based Cognitive Therapy (MBCT) with a machine learning analysis. Seventy-six psychiatric outpatients at “university hospital mental health service” had a prescription for MBCT from their referring psychiatrist. They suffer from various psychiatric illnesses with [...]

Curcumin, the yellow principle of the Indian Turmeric, ‘Haldi’ has recently attracted renewed interest in the field of experimental medicine with pleiotropic activity. This review has emphasized three pharmaceutical studies of interest: the pharmacokinetics, pharmacology, and pharmacodynamics of curcumin. In this review, we attempted to review the general pharmacokinetics profile, pharmacokinetic interactions, and pharmacokinetic-pharmacodynamic interactions of curcumin and its formulations. Different species of tu [...]

Physical activity is essential to delaying cognitive decline and preventing cognitive impairment in older adults. We designed and implemented two-level 4Active intervention for older adults living in retirement communities. This study aimed to examine the effectiveness of the 4Active intervention in increasing physical activity and cognitive function in older adults. Fifty-eight eligible older adults with a mean age of 83.83 years (76.3% females) living in two retirement communities voluntarily participated in this [...]

This study examined the correlates of change in the depressed state among people aged 65 and older during the SARS-CoV-2 pandemic, particularly the effects of crucial pandemic-related variables. Data were drawn from the longitudinal Survey of Health, Ageing and Retirement in Europe (SHARE), including information obtained from two special pandemic-related telephone interviews (N = 18, 266). The analysis regressed depressed state soon after the outbreak (T1) and again a year later (T2), on four pandemic-related varia [...]

Anthropometric measurements are frequently used to assess changes in body composition in different populations. Despite being a cheap, in-field, and relatively valid technique, the COVID-19 pandemic has impulse research on digital anthropometry across the globe. Machine learning, as the convergence of artificial intelligence and data mining, has the potential to improve data collection and analysis in the applications of kinanthropometry. Far from replacing conventional methods, digital anthropometry is a powerful [...]
