Abstract

The increasing reliance on energy-intensive active cooling systems in modern tropical architecture presents a significant challenge to sustainable development. Traditional, vernacular design strategies, such as the Islamic Mashrabiya (ornate latticework screens), offer time-tested principles for passive climate mitigation that are largely underexplored in contemporary building science. This study aims to quantitatively evaluate the effectiveness of integrating Mashrabiya-inspired building facades as a passive cooling strategy to reduce solar heat gain and enhance thermal comfort in modern tropical buildings. A quantitative, simulation-based methodology was employed. Using building performance simulation software (EnergyPlus), a prototypical contemporary office building in a hot-humid tropical climate was modeled. Several facade designs incorporating different Mashrabiya patterns, porosities, and materials were simulated and compared against a conventional glazed curtain wall baseline. Key performance indicators included indoor operative temperature, solar radiation transmittance, and annual cooling energy demand. The findings demonstrate that facades with optimized Mashrabiya-inspired designs significantly improved building performance. The best-performing screen designs reduced direct solar heat gain by up to 55% and lowered the annual cooling energy consumption by over 25% compared to the baseline, while still maintaining sufficient daylight levels.  The application of Mashrabiya principles is a highly effective and viable passive design strategy for modern tropical architecture. This research confirms that reinterpreting traditional architectural elements offers a culturally resonant and sustainable pathway to creating energy-efficient and comfortable buildings.

Abstract

The microbial communities play a crucial role in maintaining ecosystem functions by driving various biological processes, including nutrient cycling, energy flow, and species interactions. Despite extensive studies on individual species, the holistic role of microbial communities within ecosystems, particularly from a zoological and ecological perspective, remains underexplored. This study aims to analyze the interrelationship between microbial communities and ecosystem functions, emphasizing their impact on animal health, productivity, and biodiversity. The research employs a combination of field observations, laboratory analyses, and statistical modeling to investigate microbial diversity across different habitats. Field samples were collected from diverse ecosystems, including forests, grasslands, and aquatic environments, to assess microbial composition and its association with local fauna. Results indicate significant correlations between microbial diversity and ecosystem productivity, with specific microbial taxa contributing to enhanced nutrient availability and animal health. Moreover, the findings reveal that changes in microbial communities due to environmental stressors, such as climate change and habitat fragmentation, can negatively affect ecosystem resilience. In conclusion, this study highlights the pivotal role of microbial communities in supporting ecosystem functions, providing a basis for conservation strategies that integrate microbial management to enhance ecological balance and sustainability.

Abstract

Bone tissue engineering seeks to develop biomaterial scaffolds that can replicate the complex hierarchical structure and biological functionality of native bone extracellular matrix. Conventional bone substitutes often fail to simultaneously achieve sufficient mechanical strength, osteoconductivity, and biological integration, limiting their effectiveness in repairing critical-sized bone defects. This study aims to develop a collagen–nanofiber composite scaffold functionalized through biomimetic mineralization of hydroxyapatite to enhance its suitability for bone tissue engineering applications. An experimental biomaterials approach was employed, involving fabrication of collagen nanofiber scaffolds followed by controlled biomimetic mineralization in simulated physiological conditions. The resulting scaffolds were characterized for morphology, mineral composition, crystallinity, and mechanical properties, and subsequently evaluated in vitro using osteogenic cell models to assess cell adhesion, proliferation, differentiation, and matrix mineralization. The mineralized scaffolds exhibited uniform nanoscale hydroxyapatite deposition, physiologically relevant Ca/P ratios, and significantly enhanced mechanical stiffness compared to non-mineralized controls. Biological assays demonstrated improved osteogenic cell attachment, elevated alkaline phosphatase activity, and increased calcium deposition on mineralized scaffolds. These findings indicate that biomimetic mineralization effectively integrates inorganic and organic phases to produce a scaffold that closely mimics native bone structure and function. In conclusion, collagen–nanofiber scaffolds mineralized with hydroxyapatite using a biomimetic approach represent a promising platform for bone tissue engineering and warrant further in vivo investigation.
