概括
2013年至2020年间,用杀虫剂处理的网 (ITNs) 在物理耐用性和抗损坏 (RD) 方面没有得到改善. 许多ITN表现不佳,迫切需要对材料标准进行升级,并为更强大的产品开发提供激励.
科学领域:
- 公共卫生 公共卫生
- 材料科学 材料科学 材料科学
- 矢量控制控制器 矢量控制器
背景情况:
- 人们仍然担心用杀虫剂处理的网络 (ITNs) 的物理耐用性及其3年的寿命.
- 评估ITN的抗损坏性 (RD) 对于确保其长期有效性至关重要.
研究的目的:
- 为了比较 2013 年和 2020 年采集的杀虫剂处理网 (ITN) 的抗损伤 (RD) 评分,采集了 2013 年和 2020 年的样本.
- 为了确定产品开发是否随着时间的推移改善了ITN性能.
主要方法:
- 对比了2013年WHO推的ITN的RD得分和织性能数据,与2020年WHO预资格的ITN.
- 包括2013年无法使用的最新ITN产品,以评估整体绩效趋势.
主要成果:
- 2013年至2020年间,ITN的整体耐损性 (RD) 没有得到改善;一些产品表现更差.
- 同类ITN品牌的平均RD得分从2013年的40分下降到2020年的36分.
- 2020年,在24个测试的ITN产品中,只有2个超过了50的RD得分,而6个得分低于30,这表明存在明显的固有弱点.
结论:
- 由于目前的抗损伤 (RD) 水平较低,ITNs的长期物理耐用性不太可能得到改善.
- 迫切需要对织材料性能标准进行升级,并鼓励开发更持久的ITN.

01:22Toughness and Hardness of Aggregate
262
Toughness and hardness are critical properties of aggregate materials used in concrete, particularly on pavement surfaces and industrial flooring subjected to heavy loads. Toughness is defined as the aggregate's resistance to failure by impact and is measured by the aggregate impact value (AIV). For this, the aggregate impact value test is performed, wherein the impact is delivered by a standard hammer, which falls freely under its own weight onto the aggregates. The aggregates fragment in...

01:15Brick Durability, Strength, and Appearance
200
Brick durability, strength, and appearance are crucial factors in construction, influencing the choice of bricks for specific applications. The process of freeze-thaw, for instance, significantly affects brick durability. This phenomenon occurs when water absorbed by a brick expands as it freezes, potentially causing damage when it melts and refreezes. Bricks are graded for durability: SW-grade bricks are the most durable, offering high strength and low water absorption, followed by MW-grade...

01:17Mortar Properties
124
Mortar properties encompass a range of characteristics crucial for construction and masonry work, including workability, water retention, bond strength, durability, compressive strength, volume change, and appearance. Workability refers to mortar's ability to be easily applied and manipulated without sagging or falling off surfaces, which is important for efficient masonry unit placement and alignment. Water retention is essential to prevent the mortar from losing moisture too quickly to...

01:22Fatigue Strength of Concrete
192
Fatigue, in the context of materials science and engineering, refers to the weakening or failure of a material caused by repeatedly applied loads, even if these loads are below the strength limit of the material. Fatigue strength in concrete is a critical property that influences its durability and longevity. Concrete can fail in two ways due to fatigue. Static fatigue or creep rupture occurs under a constant load or one that increases slowly. The other failure mode is due to cyclical or...
