PLANTS, PEOPLE, PLANET, EarlyView.Major staple crops are often introduced and cultivated in monocultures. Yams are stable crops native to the majority of low‐ and middle‐income countries and can provide an alternative to introduced staple crops. We showed that lesser yams cultivated together with teak trees (planted at the border of the farm) are more profitable than lesser yam ...

PLANTS, PEOPLE, PLANET, EarlyView.For generations, Mediterranean communities have used Lamiaceae or Labiatae plants like rosemary, thyme or mint to care for their health and to enrich their food. By bringing together dispersed knowledge from across the Mediterranean region, our review revealed the continuing relevance of Lamiaceae while also compiling past uses that may hold future ...

Rare Metals, EarlyView.ABSTRACT Porous NiTi alloys are widely used in biomedical and engineering fields. Using the PBF‐LB technique, the TPMS and Voronoi porous parts with a porosity of ∼67% and a minimum feature size of 0.15 ± 0.02 mm were fabricated. Although the bulk sample fabricated with the same parameters is defect‐free, μ‐CT reconstruction on the porous sample ...

有色冶炼厂房事故坑附近工字型钢柱在炉料热作用下的耐火稳定性验算
Jianzhu Gangjiegou Jinzhan, 2009 为了评估有色冶炼厂房事故坑附近钢柱在炉料热作用下的耐火稳定性,本文以热辐射理论为基础,采用数值计算方法研究了钢柱9m高度内的温度分布。钢柱温度取决于炉料面积、柱翼缘厚度、柱的计算截面位置、炉料与柱相对位置。炉料面积越大,钢柱越处在炉料中部,钢柱的温度越高;柱翼缘厚度越大,炉料与柱距离越大,钢柱的温度越低。本文以弹性理论为基础,给出了钢柱耐火稳定性验算与评估方法。由于钢柱之间存在较大温差,当钢柱所支承的梁的线刚度较大,两端与柱刚接且设置隅撑时,较强的端部约束作用使柱产生较高水平的温度内力 ...

Jianzhu Gangjiegou Jinzhan, 2021 为研究不同梁柱节点构造形式对中心支撑框架抗震性能的影响,完成了4个1层1跨的中心支撑框架试件的拟静力试验,研究参数分别为:柱截面形式、梁柱连接方式、梁柱刚度比。试验结果表明:梁柱节点处构造措施的改变,使各试件的局部损伤也存在着差异;各试件的水平力-层间位移角滞回曲线均为S形,箱形柱截面的开裂与梁柱铰接连接会导致滞回曲线有一定程度的捏拢;当柱截面形式为箱形柱时,节点板附近的柱发生局部破坏,框架分担水平力降低;由于节点板的存在,梁柱间的铰接节点近似为半刚接,框架分担水平力降低,但并不影响支撑充分发挥其性能 ...

Rare Metals, EarlyView.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

Jianzhu Gangjiegou Jinzhan, 2009 本文研究了对摇摆柱提供支持的框架柱的稳定性。结果表明,存在摇摆柱的情况下,框架柱的稳定系数,除了采用放大了的长细比确定外,还要适当降低柱子曲线。通过有限元分析对比,本文建议了一个修正的缺陷因子,在现行压杆稳定系数b曲线的计算公式中应用。本文考察了带摇摆柱框架的总的承载力。结果表明,虽然摇摆柱的侧向稳定承载力是由框架柱提供的,但是在框架柱的长细比小时,总的承载力远远超出框架柱本身的稳定极限承载力。这说明,摇摆柱的承载力是由框架柱的抗侧刚度提供的,柱子长细比小的框架柱的抗侧刚度较大 ...

Rare Metals, EarlyView.ABSTRACT Silicon oxide (SiO) is becoming the main anode for high‐energy lithium‐ion batteries because of its ease of manufacture, outstanding cycling stability, and high capacity. However, low initial Coulombic efficiency (ICE) caused by the irreversible reaction of silica, as the main issue, strictly limits its commercial applications.

Rare Metals, EarlyView.ABSTRACT Reliable operation of high‐performance magnetostrictive devices, composed of the giant magnetostrictive material (GMM), that is, the TbDyFe alloy, critically depends on an optimally tailored bias magnetic field. Sufficient intensity and uniformity are essential to induce the ideal initial strain in the GMM, enabling peak reciprocating output ...
