关键词： 熔融金属   防护服   纤维原料   织物组织   滑脱性   隔热性  

摘要： 探究防熔融金属飞溅织物的防护机理,并对其影响因素进行试验分析。通过对熔融金属的特性以及织物在熔融金属作用下力学作用与热传递作用的分析,揭示了熔融金属飞溅的防护机理。测试了不同织物的抗熔融金属冲击性,从纤维原料和织物组织两方面进行了相关分析。试验结果表明:纤维种类是影响织物抗熔融金属冲击性的主要因素,其次是织物组织;织物紧度越大、组织系数越小,织物的抗熔融金属冲击性越好;织物厚度的影响不明显。认为:防熔融金属飞溅性能的关键在于实现面料的滑脱性与隔热性;从纤维配伍、织物紧度与组织结构三方面综合考虑,可提升面料的滑脱性,从而实现高等级熔融金属飞溅防护服的开发。

关键词： Vacuum circuit breaker cam   Stress analysis   Switchgear industry   Contact stress   Image processing  

摘要： Vacuum circuit breakers (VCBs) are widely used in the switchgear industry. Over the past decades, leading companies have conducted extensive research and development to optimize the mechanical mechanisms and understand the kinematics and dynamics behavior of VCBs. The mechanical life of these devices is crucial for safety and reliability. This paper investigates an essential component of the VCB mechanism by evaluating the stress in the cam using theoretical and numerical methods. Furthermore, the calculations are supported by examining a deformed cam in a VCB after 2500 cycles. To this end, contact stress equations for the cylindrical part of the cam and its follower were developed. The ABAQUS finite element software was employed with specified contact properties. Additionally, an image of a cam in a VCB after 2500 cycles was processed and compared to other methods. The results demonstrate that the cam exhibited alternating stress values at different local locations at the end of its profile. However, in general, the Von Mises stress increased as the location on the cam progressed from 0° to 240°.

摘要： There has been a rapid increase in the number of individuals utilizing mass spectrometry–based proteomics to study complex biological systems and questions since the start of the 2000’s. Building off the advancements in ionization and liquid chromatography scientists continued to push towards technology that would enable in-depth analysis of biological specimen. Donald F Hunt and the Hunt laboratory were major contributors to this effort with their work on improving upon existing Fourier Transform MS, development of electron transfer dissociation, and continued work on ion-ion reactions to improve intact protein analysis. Collaboration with other instrumentation laboratories and instrument companies led to the sharing of technology and eventual commercialization providing greater access. Additionally, the Hunt laboratory spread the gospel of MS-based proteomics through collaborations that lasted decades with other scientists who were experts in immunology, cellular signaling, epigenetics, and other fascinating fields. This article attempts to highlight the many contributions of Don and the Hunt laboratory to peptide and protein identification since the year 2000.

关键词： Cosmogenic surface exposure dating   Glaciers   Last Glacial Maximum   Moraine   Paleoclimate   PISM glacier modelling   Pyrenees   Younger Dryas  

摘要： The cold and dry Younger Dryas (YD) stadial (ca. 12.9 to 11.7 ka) generated glacial deposits in the Iberian Mountains, often restricted to high altitudes in cirque areas. Contrary to expectations, we encountered well-developed YD moraines at relatively low altitudes on the northern slopes of the Cadí Massif in the Southeastern Pyrenees, Spain. We applied the ³⁶Cl terrestrial cosmogenic nuclides (TCN) surface exposure dating method on 11 limestone boulders collected from three moraines to assess the glacial geochronology and paleoclimate conditions associated with their formation. We report a small but well-preserved moraine at an unusually high altitude for the Southeastern Pyrenees (between 2160 m and 2120 m above sea level; asl) fed by a small hanging glacier that formed at 23.0 ± 1.5 ka during the global Last Glacial Maximum (LGM). Four kilometres west of the LGM moraine, a ca. 2.5 km long glacier originating from one of the largest cirques of the Cadí Massif deposited a ca. 700 m long moraine preserved between 1760 m and 1600 m. As alluvial and periglacial processes heavily modified this moraine, we cautiously attribute its age to 12.9 ± 1.0 ka. This age represents the onset of the YD period following the Bølling-Allerød warming, widespread in the Pyrenees. On the other hand, another ca. 1.7 km long glacier sourced from the adjacent cirques deposited a pair of well-preserved lateral moraines and a terminal moraine ca. 1150 m long. The samples collected from the moraines yielded tightly clustered boulder ages (average age = 12.1 ± 1.1 ka). Although they developed at relatively low elevations (1830–2100 m) with an Equilibrium Line Altitude (ELA) of 2175 m, which is exceptional for the Southeastern Pyrenees, these moraines were formed during the YD stadial. Our study suggests that despite increased glacier retreat in the Mediterranean region, local relief is crucial in preserving ice masses far below the moder
