Introduction and Significance: Burn injury (BI) is a considerable health issue which is responsible for around 300,000 deaths and affecting about 11 million people every year worldwide. In Saudi Arabia, the prevalence of BIs array from 112 to 518 per 100,000 per year. The appropriate awareness of performing first aid could facilitate to improve the outcomes of burns. Purpose and Objectives: To appraise the community that acknowledges burns, first aid, and associated factors among the community population in Jazan City, Saudi Arabia. The paper aims to identify limitations to encourage additional research and persuade legislators to develop improved burn-injury care recommendations and training programs. Materials and Methods: An observational-based sample survey was conducted among the people who live in Jazan City aging 13 years or more, during April 5 to May 5, 2023. Data collection was done by a validated online self-administrated questionnaire sent randomly to community members in different parts of Jazan City via social media platforms. Collected data were coded and cleaned by an excel program, and finally exported on SPSS 26.0 software. The variables were analyzed using descriptive statistics like frequencies and percentages. Also, the Chi-square test was used to investigate the relation between different variables, with a significance value of P Results: This study included 243 participants (about 62%) among them were mostly male participants (151) having a university degree. The majority of participants 75% did not take any form of BFA training in the past. This study shows that 69.9% of the participants have inadequate awareness, despite 72% having a constructive attitude towards burn first aid. Previous burn-related first aid training was significantly associated with participants’ knowledge of BFA at a p-value less than 0.05. Conclusion: This study indicates a high frequency of Jazan population having inadequate knowledge of burn first aid despite the high

This article presents a pragmatic quadcopter development template for parcel delivery in Nigeria. The quadcopter is equipped with a camera, parcel pouch and wireless telecommunication to capture live events and send them back to the control station for real-time delivery feedback. The study also discusses the design methodology adopted as a conceptual design approach vital to product development, it encompasses information gathering and identifying the problem, creating the solutions systematically and eventually evaluating and developing a concept for the drone and its attributes and presenting clear results for design calculations.

【目的】信号肽对效应因子的分泌至关重要,影响病原微生物的致病进程。前期鉴定到在稻曲病菌侵染水稻花器官过程中显著上调表达的10个效应因子基因,但这些效应因子是否含有功能性信号肽及其表达模式尚不明确。【方法】利用SignaIP-5.0数据库预测、烟草瞬时表达系统和酵母信号肽分泌实验,分析并鉴定这些效应因子的信号肽。利用实时荧光定量PCR技术,检测效应因子基因的表达模式。【结果】UV_44、UV_1548、UV_1567等10个稻曲病菌效应因子均含有信号肽。烟草瞬时表达结果显示,含有信号肽的eYFP融合蛋白在细胞质壁分离后均能分泌到质外体空间。酵母菌信号肽分泌结果显示,分别携带这10个信号肽的酵母菌株可在以棉子糖为唯一碳源的培养基上生长,且与TTC发生显色反应。实时荧光定量结果表明,除了UV_6754,其余9个效应因子基因的表达模式不尽相同,其中UV_44、UV_1567、UV_3667、UV_4213、UV_4989、UV_5215和UV_8184的表达量在接种后显著升高。【结论】这10个稻曲病菌效应因子均含有分泌功能的信号肽,编码效应因子的基因在稻曲病菌侵染过程中具有不同的表达模式。该结果为深入研究以上稻曲病菌效应因子的功能奠定了基础。

介电电容器具有重量轻、充放电速度快、功率密度高等优点,在航空航天储能器件领域的作用日益凸显。采用模板法与电泳沉积法相结合制备了多尺度结构的柔性复合电介质材料钛酸钡/聚二甲基硅氧烷(BTO/PDMS),研究了其微观无序、有序结构对介电性能的影响,并通过理论模拟对其介电与介电强度性能进行了系统分析,为提高复合电介质储能密度的研究提供了理论铺垫。结果表明:当BTO含量达到10.16%(质量分数)时,复合材料的相对介电常数在1000 Hz时提升到85(纯PDMS的相对介电常数仅为2.75);当BTO的体积分数在5%∼20%之间变化时,介电常数随BTO含量的增加呈线性增加;此外,通过调控BTO形貌的有序定向结构(如四方或蜂窝定向结构),介电性能得到提升,某些特定方向的介电强度性能显著提高;将聚偏氟乙烯(PVDF)和PDMS复合形成核壳结构,常数略有提升,填料与基体的介电性能差异减小,介电强度性能得到提升。
