In the realm of military and defence applications, exposure to radiation significantly challenges the performance and reliability of solder alloys and joints in electronic systems. This comprehensive review examines radiation-induced effects on solder alloys and solder joints in terms of microstructure and mechanical properties. In this paper, we evaluate the existing literature, including experimental studies and fundamental theory, to provide a comprehensive overview of the behavior of solder materials under radiation. A review of the literature highlights key mechanisms that contribute to radiation-induced changes in the microstructure, such as the formation of intermetallic compounds, grain growth,micro-voids and micro-cracks. Radiation is explored as a factor influencing solder alloy hardness,strength, fatigue and ductility. Moreover, the review addresses the challenges and limitations inherent in studying the effects of radiation on solder materials and offers recommendations for future research. It is crucial to understand radiation-induced effects on solder performance to design robust and radiationresistant electronic systems. A review of radiation effects on solder materials and their applications in electronics serves as a valuable resource for researchers, engineers, and practitioners in that field.

本研究采用旅游生态足迹模型，对山地风景区的绿色发展状况进行细致评估，其整体目标在于全面分析旅游活动对生态环境所带来的影响。评估过程包括对生态足迹、生态承载力以及生态盈余的计算和分析。在文峰山风景区的个案研究中，研究结果显示，当前文峰山风景区旅游业发展阶段呈现出显著的生态盈余状态。生态足迹的盈余意味着旅游活动对文峰山风景区生态环境的影响并未超过其可持续承载能力。这说明尽管旅游活动蓬勃发展，但文峰山风景区的生态环境仍然得到有效保护和维护。生态盈余的存在标志着旅游业发展与当地生态系统保护之间的平衡，这对于该地区的可持续发展至关重要。此外，本研究对旅游生态足迹组成部分进行深入分析，提供关于各种旅游相关活动（如住宿、交通、餐饮、观光和购物等）所带来的生态足迹的详细细分。这些细致的分析为了解不同旅游相关因素所带来的生态动态提供深入分析。对文峰山风景区绿色发展状况的精细评估具有重要意义，决策者可以从中获得旅游促进和环境保护之间微妙平衡的见解。所发现的生态盈余表明目前的做法符合可持续发展目标，并为类似地区提供了一个典范。然而，本研究也凸显运用旅游生态足迹模型进行计算的关键局限性，详细的结果揭示模型适用性、数据收集以及计算方法等方面存在的挑战，强调有必要对旅游生态足迹模型进行进一步完善和验证。认识到这些限制对于改进模型并确保其在不同地理环境中的稳健应用至关重要。本研究提供对山地型风景区，尤其是文峰山风景区的绿色发展状况的深入理解。研究结果为决策者和研究人员提供丰富的参考资料，提供有关旅游相关生态影响特定方面的见解。未来的研究可以在完善评估指标和改进数据收集以及分析方法方面继续努力，以提高绿色发展评估的准确性和可靠性。

In recent years, zinc oxide nanoparticles(ZnO NPs) have gained tremendous attention attributed to their unique properties. Notably, evidence has shown that zinc is an important nutrient in living organisms. As such, both prokaryotes and eukaryotes including bacteria, fungi and yeast are exploited for the synthesis of ZnO NPs by using microbial cells or enzyme, protein and other biomolecules compounds in either an intracellular or extracellular route. ZnO NPs exhibit antimicrobial properties, however, the properties of nanoparticles(NPs) are depended upon on their size and shape, which make them specific for various applications. Nevertheless, the desired size and shape of NPs can be obtained through the optimization process of microbes mediated synthesis by manipulating their reaction conditions. It should be noted that ZnO NPs are synthesized by various chemical and physical ***, these methods are expensive and not environmentally friendly. On that account, the microbes mediated synthesis of ZnO NPs have rapidly evolved recently where the microbes are cleaner, eco-friendly, nontoxic and biocompatible as the alternatives to chemical and physical practices. Moreover, zinc in the form of NPs is more effective than their bulk counterparts and thus, they have been explored for many potential applications including in animals industry. Notably, with the advent of multi-drug resistant strains, ZnO NPs have emerged as the potential antimicrobial agents. This is mainly due to their superior properties in combating a broad spectrum of pathogens. Moreover, zinc is known as an essential trace element for most of the biological function in the animal’s body. As such, the applications of ZnO NPs have been reported to significantly enhance the health and production of the farm animals. Thus, this paper reviews the biological synthesis of ZnO NPs by the microbes, the mechanisms of the biological synthesis, parameters for the optimization process and their potential

The development of microbial-based products requires certain criteria for them to be successfully commercialized. The product must meet the following desirable criteria: effectiveness, contamination free, stability, cost-effectiveness, and a prolonged shelf life. Controlling the drying process is crucial for ensuring the stability and durability of the product. The traditional approach, which involved mechanical and natural drying, led to decreased productivity and quality. The objective of this research endeavour was to achieve a dry process enhancement while preserving the microbial quality of Trichoderma asperellum (M103). The temperature and relative humidity during the drying period were monitored under two conditions: with and without a dehumidifier. The results demonstrate that the dehumidifier increases drying period efficiency by up to 63%.

平菇（Pleurotus spp.）是全球最广泛栽培的蘑菇品种之一。本研究旨在探讨合生元对Pleurotus ostreatus和Pleurotus pulmonarius生长和品质的影响。通过每日对蘑菇样品喷洒不同浓度的合生元，测量其生长参数、产量、生物效率、近似成分、矿物质含量、总酚含量和二苯基-1-三硝基苯肼（DPPH）自由基清除活性。结果表明，使用喷洒菊粉和干酪乳杆菌的合生元，平菇的产量最高（56.92克），生物效率也最高（12.65%）。菊粉和干酪乳杆菌的组合最为高效，可以同时提高两种样品蘑菇的生长性能和营养成分。此外在白平菇（***）中，菊粉和干酪乳杆菌组合的合生元可产生最高的总酚含量（20.550 mg GAE/g DE），而在灰蘑菇（P. pulmonarius）中产生最高总酚含量的是干酪乳杆菌（1.098 mg GAE/g DE），其次是菊粉和干酪乳杆菌（1.079 mg GAE/g DE）。DPPH结果表明，平菇可以作为一种有效的抗氧化剂。综上，合生元可通过增加酚类化合物的含量来提高蘑菇的抗氧化能力，并通过增加矿物质元素的含量来提供更好的健康益处，从而提高了蘑菇的品质。上述研究证明了合生元作为一种生物肥料用于蘑菇栽培的应用潜力，是帮助蘑菇种植者解决质量不稳定的一个有效方案。
