Abstract	Traditional combat sports equipment usually uses synthetic materials, such as polyurethane and synthetic leather. Although these materials have a certain degree of strength and durability, they have poor flexibility and antibacterial properties, making it difficult to provide stable support and protection for athletes. In order to enhance the antibacterial properties and flexibility of sports equipment and reduce the risk of injuries to athletes, this article conducts in-depth research on the development of combat sports equipment using conjugated polymers. This article first selects polypropylene (PP) as the base material for sports equipment for combat athletes, and uses the gas phase polymerization method to prepare the material; then uses chitosan as an antimicrobial agent and uses the oxidative degradation method to prepare it; after that, this article coats the chitosan antibacterial agent on the prepared PP material, and uses a combination of dipping and calendering for antibacterial treatment; finally, this article uses the spunbond melt-blown composite method to fill and combine the top equipment of combat athletes to achieve the structural design of sports equipment. In order to verify the effectiveness of the equipment, this article conducted equipment performance testing and sports injury simulation. The results showed that the average diameter of the antibacterial zone of this sports equipment reached more than 1 mm, and in the injury risk test, the risk of athletes' joint and muscle injuries was reduced by 16.9% and 20.5% respectively. Research shows that developing combat sports equipment based on conjugated polymers can help reduce the risk of injury to athletes and improve the safety of combat sports.

Abstract	The increasing concentration of Antimony (Sb) in ecological environments has raised serious concerns about its potential biotoxicological impact. This study investigated the toxicokinetics, Global DNA Methylation (GDM), biomarker expression, and Integrated Biological Response (IBR) of Sb at different concentrations in zebrafish. The toxic mechanism of Sb exposure was simulated using molecular dynamics (MD). The results showed that significant differences effect existed (BCF

Abstract	As a significant sector within the tourism industry, desert tourism has developed rapidly in recent years, contributing significantly to local economic development. On the other hand, desert tourism is constantly influenced by the desert climate, characterized by high temperatures, aridity, and dust events. This study examines and analyzes the impact of dust events on the Holiday Climate Index (HCI) using an improved methodology. It incorporates comprehensive meteorological data including temperature, relative humidity, cloud cover, precipitation, wind speed and dust events of Tazhong, located in the heart of the Taklimakan Desert. The results indicate that the maximum mean monthly HCI dips from an ideal level (91) to a very good level (73), the minimum dips from good level (66) to a marginal level (47), and the annual comfortable days (HCI ≥ 80) decrease from 180.5 to 95.3 after considering the impacts of dust events. The corrective HCI indicates that autumn, especially October, offers relatively comfortable climatic conditions for tourism, with the mean monthly comfortable days reach 20.1. These findings can better guide desert tourism activities and also demonstrate that the impact of dust weather on tourism activities cannot be ignored.

Abstract	Laparoendoscopic single-site surgery (LESS) has become a novel minimally invasive approach applied as an option to perform hysterectomy. The aim of the study was to evaluate the influence of LESS hysterectomy on the sexual function in women with benign gynecologic indications. From October 2016 to May 2021, a total of 486 premenopausal, sexually active women were eligible. Female sexual function index (FSFI) was used to assess sexual function preoperatively and 6, 12 months postoperatively. Total FSFI score ≤26.55 indicated female sexual dysfunction (FSD). Compared with pre-operation, each subdomain and total FSFI scores increased at 6 (all

Abstract	This paper investigates the effect of equivalence ratio on pollutant formation characteristics of CH 4 O/H 2 /NH 3 ternary fuel combustion and analyzes the pollutant formation mechanisms of CO, CO 2 , and NO X at the molecular level. It was found that lowering the equivalence ratio accelerates the decomposition of CH 4 O, H 2 , and NH 3 in general. The fastest rate of consumption of each fuel was found at φ = 0.33, while the rates of CH 4 O and NH 3 decomposition were similar for the φ = 0.66 and φ = 0.4. CO shows an inverted U-shaped trend with time, and peaks at φ = 0.5. The rate and amount of CO 2 formation are inversely proportional to the equivalence ratio. The effect of equivalence ratio on CO 2 is obvious when φ > 0.5. NO 2 is the main component of NO X . When φ < 0.66, NO X shows a continuous increasing trend, while when φ ≥ 0.66, NO X shows an increasing and then stabilizing trend. Reaction path analysis showed that intermediates such as CH 3 and CH 4 were added to the CH 4 O to CH 2 O conversion stage as the equivalence ratio decreased with φ ≥ 0.5. New pathways, CH 4 O→CH 3 →CH 2 O and CH 4 O→CH 3 →CH 4 →CH 2 O, were added. At φ ≤ 0.5, new intermediates CHO 2 and CH 2 O 2 were added to the CH 2 O to CO 2 conversion stage, and new pathways are added: CH 2 O→CO→CHO 2 →CO 2 , CH 2 O→CO→CO 2 , CH 2 O→CHO→CO→CHO 2 →CO 2 , and CH 2 O→CH 2 O 2 →CO 2 . The reduction in the number of radical reactions required for the conversion of NH 3 to NO from five to two directly contributes to the large amount of NO X formation. Equivalent ratios from 1 to 0.33 corresponded to 12%, 21.4%, 34%, 46.95%, and 48.86% of NO 2 remaining, respectively. This is due to the fact that as the equivalence ratio decreases, more O 2 collides to form OH and some of the O 2 is directly involved in the reaction forming NO 2 .

Abstract	Multiple industries face challenges in achieving green growth that needs a fix. This research presents an alternative explanation for the acquisition of green growth using the perspective of employees of manufacturing industries. Thus, the study examines the role of green HRM, green career adaptability, and green career success in achieving green growth. Green growth drivers can construct green infrastructures for developing green aspects in economic sectors such as power generation, transportation, and the residential sector. We inquired Chinese SME employees to fill out a closed-ended online survey. PLS-SEM techniques are used to estimate how the study will turn out. According to the results, green career adaptability plays a big part in green HRM and career success. It also plays a significant role in bringing the two together. The results shown that green HRM, adapting to a green career and doing well in a green career, all help green growth in manufacturing SMEs in China. The study's results are strong in their ability to explain. This is especially true in the academic world, where people who can adapt to setbacks and have a green career are likelier to have a good career in organizations that care about the environment. By doing this, the study also helps guide the strategic development goals (SDGs) for climate action and environmental management by acquiring green growth. So, the study makes different suggestions for what to do.

Abstract	The induced pluripotent stem cells (iPSCs) line was generated using peripheral blood mononuclear cells (PBMCs) from a healthy 1-month-old boy. Expression of pluripotency markers, deletion of free episomal vectors, preservation of normal karyotype, and potential for in vitro trilineage differentiation were demonstrated in the iPSCs line SDQLCHi048-A. This cell line may serve as a basis for disease modeling and help to further explore the molecular pathogenesis.
