Abstract The concrete panel of earth-rock dams in cold regions tends to crack due to the combination effect of non-uniform foundation settlement, ice expansion loads, and freeze-thaw damage. In this work, simulations are designed to investigate the effects of freeze-thaw damage degrees on the fracture behavior caused by the partial detachment and ice expansion loads on concrete panels. Results show that the range of detached panels and freeze-thaw damage degree are the dominant factors that affect the overall load-bearing capacity of the panel and the failure cracking modes, whereas the panel slope is a secondary factor.

Abstract LONELY GUY (LOG) is a pivotal cytokinin-activating enzyme that plays an important role in plant growth, development, and stress responses. Walnut (Juglans regia), an important woody oilseed species, has not yet undergone systematic identification of its LOG gene family. In this study, we identified 17 JrLOG genes in the walnut genome, which are unevenly distributed across 11 chromosomes. JrLOG gene expansion was primarily driven by gene duplication, along with purifying selection. Members of the JrLOG family were categorized into five groups, each exhibiting analogous gene structures, featured motifs, and conserved domains.

Abstract Background: Prior research has established that exposure to low temperatures adversely affects ovarian function, yet the precise mechanisms remain to be elucidated. Methods: Thirty experimental rats, each demonstrating two regular estrous cycles, were assorted randomly into three distinct groups: a control group, a cold exposure group, and a group treated with 4-phenylbutyric acid (4-PBA). To mimic the conditions of cold exposure, rats in the cold exposure and 4-PBA groups were subjected to immersion in ice water for 21 days. After 7 days of exposure to ice water, the 4-PBA group received intraperitoneal injections of a… More >

Abstract Wire and Arc Additive Manufacturing (WAAM) technology has the advantages of high-efficiency and low-cost to fabricate large-scaled components with medium-complexity. 2319 aluminum alloy is a widely used in aerospace and military industries. Problems of porosity, residual stress, distortion, and poor mechanical properties were focused on in this paper. The mechanism of defect formation during fabrication and strengthening mechanism of peening process were investigated. In order to learn the droplet transfer and molten pool flow behavior, CFD models of molten pools for the pulse mode of CMT (CMT + P) and pulse reverse polarity CMT mode… More >

Abstract Chilling is one of the major abiotic stresses for plants, especially for rice cultivation. Many essential metabolic processes for growth and development are temperature-dependent. In that case, reducing the negative effects of cold stress using exogenous chemicals is a possible option. Therefore, the current study examined the effects of pre-sowing seed treatment with different chemicals, viz. hydrogen peroxide (H₂O₂), salicylic acid (SA), calcium chloride (CaCl₂), thiourea (TU), and citric acid (CA) on the germination of rice seeds (cv. BRRI dhan28) under chilling environments. Rice seeds were soaked in distilled water (control), 10 mM CA, 2 mM SA,… More >

Abstract Loquat (Eriobotrya japonica Lindl.), a rare fruit native to China, has a long history of cultivation in China. Low temperature is the key factor restricting loquat growth and severely affects yield. Low temperature induces the regeneration and metabolism of reduced glutathione (GSH) to alleviate stress damage via the participation of glutathione S-transferases (GSTs) in plants. In this study, 16 GSTs were identified from the loquat genome according to their protein sequence similarity with Arabidopsis GSTs. On the basis of domain characteristics and phylogenetic analysis of AtGSTs, these EjGSTs can be divided into 4 subclasses: Phi, Theta, Tau… More >

Abstract The WRKY transcription factor gene family is one of the unique gene families in plants. It plays an important role in response to abiotic stresses such as cold and drought, hormone signal transduction, regulation of biosynthesis, leaf senescence seed germination, etc. However, little information is available about WRKY transcription factors in Verbena bonariensis. In this study, 70 VbWRKY genes were identified from the whole genome. The phylogenetic analysis of the WRKY gene family in V. bonariensis and Arabidopsis shows that the WRKY genes in V. bonariensis can be divided into three groups: I, II, and III, which contain 13, 47, and… More >

Abstract Electrification of vehicles intensifies their cooling demands due to the requirements of maintaining electronics/electrical systems below their maximum temperature threshold. In this paper, passive cooling approaches based on heat pipes have been considered for the thermal management of electric vehicle (EV) traction systems including battery, inverter, and motor. For the battery, a heat pipe base plate is used to provide high heat removal (180 W per module) and better thermal uniformity (<5°C) for the battery modules in a pack while downsizing the liquid cold plate system. In the case of Inverter, two phase cooling system… More > Graphic Abstract

Abstract The formation of ice on the leading edge of aircraft engines is a serious issue, as it can have catastrophic consequences. The Swirl Anti-Icing (SAI) system, driven by ejection, circulates hot fluid within a 360° annular chamber to heat the engine inlet lip surface and prevent icing. This study employs a validated Computational Fluid Dynamics (CFD) approach to study the impact of key geometric parameters of this system on flow and heat transfer characteristics within the anti-icing chamber. Additionally, the entropy generation rate and exergy efficiency are analyzed to assess the energy utilization in the… More >

Abstract Pitting corrosion is harmful during bridge construction, which will lead to uneven roughness of steel surfaces and reduce the thickness of steel. Hence, the effect of pitting corrosion on the mechanical properties of cold-formed thin-walled steel stub columns is studied, and the empirical formulas are established through regression fitting to predict the ultimate load of web and flange under pitting corrosion. In detail, the failure modes and load-displacement curves of specimens with different locations, area ratios, and depths are obtained through a large number of non-linear finite element analysis. As for the specimens with pitting… More > Graphic Abstract
