Fire incidents in commercial vehicles pose significant risks to passengers, drivers, and cargo. Traditional fire extinguishing systems, w.ile effective, may have limitations in terms of response time, coverage, and human intervention [1]. This study investigates the efficacy of a novel fire suppression technology—the Exploding Fire Extinguishing Ball (EFEB) —as an alternative and complementary fire safety solution for commercial vehicles. The research employs a multidisciplinary approach, encompassing engineering, materials science, fire safety, and human factors analysis. A systematic literature review.establishes a comprehensive understanding of existing fire suppression technologies, including EFEBs. Subsequently, this study analyzes the unique features of EFEBs, such as automatic activation, as w.ll as manual activation upon exposure to fire, and their potential to provide rapid, localized, and autonomous fire suppression. The study presents original experimental investigations to assess the performance and effectiveness of EFEBs in various fire scenarios representative of commercial vehicles. Experiments include controlled fires in confined spaces and dynamic simulations to emulate real-w.rld fire incidents. Data on activation times, extinguishing capability, and coverage area are collected and analyzed to compare the efficacy of EFEBs w.th traditional fire extinguishing methods. Furthermore, this research show. the practical aspects of implementing EFEBs in commercial vehicles. A feasibility study examines the integration challenges, cost-benefit analysis, and potential regulatory implications. The study also addresses the impact of EFEBs on vehicle w.ight, stability, and overall safety. Human factors and user acceptance are crucial elements in adopting new.safety technologies. Therefore, this research utilizes an experimental design to assess the performance and effectiveness of EFEBs in various fire scenarios representative of commercial vehicles. This disse

Emerging insights into the function of very long chain fatty acids at cerebellar synapses

Neural Regeneration Research 2025年第6期20卷 1709-1710页

作者： Martin-paul Agbaga Mohiuddin Ahmad Department of Cell Biology and Ophthalmology University of Oklahoma Health Sciences Centerand Dean McGee Eye InstituteOklahoma CityOKUSA

Very long chain-saturated and-polyunsaturated fatty acids(VLC-SFA and VLC-PUFA, respectively) are a functionally important class of fatty acids containing 28 carbons or more in their acyl chain. They are synthesized by the elongation of very long fatty acids-4(ELOVL4) enzyme, expressed mainly in the brain, retina, skin, testes, and meibomian gland, w.ere these fatty acids are found(Agbaga et al., 2008). Further, these organs exhibit tissuespecific VLC-PUFA and VLC-SFA biosynthesis and incorporation into complex lipids for specific functions. In the brain, skin, and Meibomian glands, the ELOVL4 mainly makes VLC-SFA, w.ich are incorporated into complex sphingolipids. In the retina, the ELOVL4 makes VLC-PUFA that are incorporated into phosphatidylcholine, that are critical for visual function, w.ile in testes and sperm, the VLC-PUFA are incorporated into sphingolipids that are critical for fertility(Yeboah et al., 2021).

作者： paul w. Cleary CSIRO Mathematical and Information Sciences Private Bag 33 Clayton South 3169 Australia

Simulation of industrial particle flow. using DEM （Discrete Element Method） offers the opportunity for better understanding of the flow.dynamics by the inclusion of particle scale physics that often determine the nature of these flow.. Increased understanding from the models can lead to improvements in equip- ment design and operation, potentially leading to large increases in equipment and process efficiency, throughput and]or product quality. Industrial applications are typically large and involve complex par- ticulate behaviour in complex geometries. This paper explores the critical influence of particle shape on granular system behaviour and then discusses examples of DEM applied to several large industrial problems. 2009 Chinese Society of Particuology and Institute of Process Engineering, Chinese Academy of Sciences.

Assessing mixing characteristics of particle-mixing and granulation devices

引用

Particuology 2008年第6期6卷 419-444页

作者： paul w. Cleary Matthew.D. Sinnott CSIRO Mathematical and Information Sciences

The mixing of particulates such as pow.ers is an important process in many industries including pharmaceuticals, plastics, household products （such as detergents） and food processing. The quality of products depends on the degree of mixing of their constituent materials w.ich in turn depends on both geometric design and operating conditions. Unfortunately, due to lack of understanding of the interaction betw.en mixer geometry and the granular material, limited progress has been made in optimizing mixer design. The discrete element method （DEM） is a computational technique that allow. particle systems to be simulated and mixing to be predicted. Simulation is an effective w.y of acquiring information on the performance of different mixers that is difficult and/or expensive to obtain using traditional experimental approaches. Here w. demonstrate how.DEM can be used to unravel flow.dynamics and assess mixing in several different types of devices. These devices used for mixing and/or granulation of particulates, are classified broadly as gravity controlled, bladed and high shear. w. also explore the role of particle shape in mixing performance and use DEM to test w.ether Froude number scaling is suitable for predicting scale performance of rotating mixers.

Earthquake Engineering and Engineering Vibration 2007年第4期6卷 409-416页

This paper presents a robust H∞ output feedback control approach for structural systems w.th uncertainties in model parameters by using available acceleration measurements and proposes conditions for the existence of such a robust output feedback controller. The uncertainties of structural stiffness, damping and mass parameters are assumed to be norm-bounded. The proposed control approach is formulated w.thin the framew.rk of linear matrix inequalities, for w.ich existing convex optimization techniques, such as the LM1 toolbox in MATLAB, can be used effectively and conveniently. To illustrate the effectiveness of the proposed robust H∞ strategy, a six-story building w.s subjected both to the 1940 E1 Centro earthquake record and to a suddenly applied Kanai-Tajimi filtered w.ite noise random excitation. The results show.that the proposed robust H∞ controller provides satisfactory results w.th or w.thout variation of the structural stiffness, damping and mass parameters.

Evaluation of fall armyw.rm resistance in maize germplasm lines using visual leaf injury rating and predator survey

引用

Insect Science 2014年第5期21卷 541-555页

作者： Xinzhi Ni w.nw.i Xu Michael H. Blanco w. paul w.lliams USDA-ARS Crop Genetics and Breeding Research Unit University of Georgia-Tifton Tifton GA 31793 Agricultural Research &Extension Center Texas A&M University Lubbock TX 79403 USDA-ARS Plant Introduction Research Unit Iowa State UniversityAmes IA 50011 Corn Host Plant Resistance Research Unit USDA-ARS Mississippi State MS 39762 USA

After examining ear-colonizing pest resistance, 20 maize lines from the USDA- ARS Germplasm Enhancement of Maize （GEM） Program w.re evaluated for w.orl-feeding fall armyw.rm （FAw. （Spodopterafrugiperda） resistance using 4 maize inbred lines as the resistant and susceptible controls. Both FAw.injury ratings at 7- and 14-d after infestation, and predator abundance and diversity at w.orl stage （V6-V8） w.re recorded in 2009 and 2010. The survey of the diversity and abundance of predators in each experimental plot w.re conducted 7 d after the FAw.infestation. Of the 20 germplasm lines examined, 3 of them （i.e., entries 9, 15, and 19 that w.re derived from tropical maize germplasm lines w.re originated from Uruguay, Cuba, and Thailand, respectively） w.re identified as the best FAw.resistant germplasm lines using the leaf injury ratings and predator survey data. In addition, the abundance and diversity of the predators w.re greater in 2010 than in 2009, w.ich might have caused the low.level of the FAw.injury ratings on all lines examined in 2010. The 2-year data show.d that the FAw.injury ratings w.re negatively correlated to the predator abundance and diversity, w.ich is also influence by genotype × environment interactions. The findings suggested that tropical germplasm is an important source of native resistance to the FAw.and the corn earw.rm. At the same time, the maize genotype x environment interaction （e.g., predator attractiveness, and varying w.ather conditions） should be included in the multiple-year evaluations of insect and disease resistance of maize germplasm lines under field conditions.
