在碳纤维增强树脂基复合材料轻量化与结构性能持续提高的前提下，同时附加其特定的功能，尤其是在不损失、甚至提升其层间断裂韧性的情况下，不仅可以弥补结构复合材料天然的缺陷，例如树脂基体的电绝缘性，也可以使其满足特定产品的要求，例如高刚度兼具一定的吸声降噪特性等。显然，对于航空航天这样的尖端应用领域，这种功能附加或结构功能一体化的复合材料技术对航空航天技术的未来发展至关重要。本文介绍了4种具有典型性的结构功能一体化复合材料的设计、制备与性能研究，分别是基于层间功能化插层和基于内织导电纬纱的导电增韧一体化复合材料及多级孔碳化棉纤维填充蜂窝/微穿孔面板的夹芯复合材料结构和编织布/无纺纤维毡复合材料片材折叠成型的结构吸声一体化复合材料。前两种材料分别通过在复合材料富树脂的层间插入导电功能化插层和在复合材料内引入贯通整个材料的导电纬纱网络实现了复合材料的导电性能与层间韧性的同步提高，而后两种材料则分别通过多级孔结构的碳化棉纤维材料填充蜂窝/微穿孔面板夹芯技术和编织布/无纺纤维毡复合材料片材的折叠技术实现了良好的吸声性能等，以展示多尺度、多层次结构设计和制备技术在结构复合材料功能化集成和结构功能一体化方面的应用。

在英国脱欧问题上为年轻人做一点事情不仅是富有同情心的明智之举,而且是人心所向,如果基尔·斯塔默(Keir Starmer)在这个问题上仍然犹豫不决,那么工党在下院选举中赢得多数席位又有什么意义?在八月底访问柏林期间,这位工党首相重申,英国不打算加人“青年流动计划”。根据该计划,英国年轻人可以在欧盟生活、学习和工作几年,同时,来自欧洲大陆的30岁以下年轻人也能享受互惠安排。

本文在修辞批评的视域内探讨了病毒式宣传这一现象,指出就其传播方式而言,宣传具有病毒属性。鉴于这一属性本质上是一种修辞建构,从修辞视角来分析病毒式宣传讯息将富有成效。文章首先讨论了修辞和修辞批评之于宣传的重要性,之后分析了病毒传播和宣传的核心概念——病毒或传染隐喻,以及病毒传播概念的营销根源。最后,运用修辞方法专门研究了围绕着模因及模因学而形成的话语。本文的讨论将对有关政治传播和说服的理解产生影响,并使我们在思考互联网模因的本质及其在现代宣传中的地位时更具批判性。

我第一次接触法国的ATOLL这个品牌是在四年前,当时我们当地的经销商借出了一台该品牌的放大器作评估。我记得对这台机器的印象非常深刻。但后来这个英国经销商停止进口这个品牌,所以ATOLL暂时从我的脑海消失了,直到我在最近的一次展会上发现了由新的经销商再度引入的它。因此,现在是时候对ATOLL进行评测了,这次所选的是内置解码器的IN300 Signature合并式放大器。

World Journal of Cardiovascular Diseases 2024年第2期14卷 88-98页

Wafeu Faculty of Medicine and Biomedical Sciences University of Yaoundé I Yaoundé Cameroon Cardiology Department Yaoundé Central Hospital Yaoundé Cameroon Centre for Research on Filariasis and Other Tropical Diseases Yaoundé Cameroon

Background: Venous thromboembolism (VTE) is among the leading causes of hospital-related disability-adjusted life years lost. We aimed to determine the prevalence and determinants of functional capacity impairment six to twelve months after an acute VTE event. Methods: This was a cross-sectional study conducted between January and April 2021 in two referral hospitals of Yaoundé, including consenting adult patients admitted to these hospitals six to twelve months ago for VTE. We excluded dead patients and those with any comorbidity or symptoms limiting physical activity. The functional outcome was assessed with the six-minute walk test. Functional capacity impairment was defined as walking distance lower than the expected value. Results: We included 27 cases in this study with a mean age of 53.2 ± 14.4 years. The prevalence of functional capacity impairment was 29.6% (95% CI: 14.8 - 48.1). Factors associated with poor functional outcome were obesity (OR: 59.5;95% CI: 4.6 - 767.2;p - 207.4;p = 0.017), massive PE (OR: 30;95% CI: 2.5 - 354;p = 0.004), and poor adherence to treatment (OR: 30.3;95% CI: 2.5 - 333.3;p = 0.004). Conclusion: Functional capacity impairment is common in the medium-term after VTE and factors associated with this poor outcome are obesity, the severity of the VTE, and poor adherence to treatment.

Advances in Aging Research 2024年第4期13卷 61-74页

作者： chris Griffiths Farah Hina Chee Siang Ang Louise Birkett-Swan Casey Bonham Lauren Currell Emily Ward Natasha Stace-Wood Jessica Plumbridge Northamptonshire Healthcare NHS Foundation Trust Northampton UK School of Computing University of Kent Canterbury UK

Research Background: Compared to the general population, people experiencing age-related cognitive decline are more likely to have low levels of physical activity and sleep problems. Sufficient physical activity and quality sleep are protective factors against cognitive decline and poor health and can improve coping with stressors. The “Active Feedback” intervention comprises a wearable activity and sleep tracker (Fitbit), access to Fitbit software healthy lifestyle software apps;one session with Memory Assessment Service (MAS) staff providing physical activity and sleep hygiene advice and two further engagement, discussion, and feedback sessions. Purpose/Aim: This study investigates the acceptability and feasibility of Active Feedback and the effect on stress, mental wellbeing, and sleep quality, and the links between these factors. Methods: An open-label patient cohort design with no control group was used. Pre-intervention, 4-week and 8-week intervention assessments were performed using participant self-report measures: Perceived Stress Scale (PSS), Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), and Sleep Conditioning Index (SCI). Twenty-five participants completed an eight-week three-session intervention (18 males and 7 females), with the age range of 66 - 84 years old, and average age of 73.8 years (SD = 5.09). Fifteen participants had a diagnosis of MCI, ten participants did not. Results: There were non-significant improvements in SCI scores from 21.0 (SD = 8.84) to 21.6 (SD = 6.20) at 8 weeks, PSS scores from 17.5 (SD = 5.89) to 17.0 (SD = 6.20) at 8 weeks, and WEMWBS scores from 46.9 (SD = 9.23) to 48.8 (SD = 9.69) at 8 weeks. There were negative correlations between WEMWBS and PSS. Conclusion: Active Feedback intervention was found to be feasible and acceptable. Active Feedback could be enhanced to include motivational interviewing and goal setting.

泰格·伍兹对Scotty Cameron推杆的钟爱,使该品牌的球杆成了艺术品,甚至成为一种真正的资产类别。它们真的值得人们如此喜爱吗?很少有运动器材比推杆更加个性化的了。它被用来完成体育运动中一个比较精细的任务:让球缓慢滚动3英尺、10英尺或20英尺。除非遇到特殊情况,否则它会是高尔夫球手在每个球洞都会使用的唯一球杆。推杆功能的微妙之处掩盖了人们与这根球杆之间强大的情感联结。它不像鞋子那样在几周或几个月后会磨损、撕裂和更换。
