The migration of the IVC filter into the heart chamber is a rare and dangerous complication. There are few data describing the successful treatment of this pathology in the world literature. The use of open surgery with the initiation of cardiopulmonary bypass is the "gold standard", however, the initial condition of patients and concomitant pathology can worsen the outcomes of treatment. The endovascular approach to such patients is the optimal method. Endovascular explantation of a migrated IVC filter is feasible, but readiness of the cardiac team is a key factor.

This review highlights sustainable materials, recycling strategies, and emerging technologies such as AI, LCA, and self-healing rubber, guiding the tyre industry towards eco-friendly, circular, and innovative future solutions.

Наличие влаги может нанести вред силовым трансформаторам, ускоряя процессы старения, уменьшая диэлектрический запас, начальное напряжение частичного разряда, что в свою очередь повышает риск неожиданных сбоев. Современные электротехнические предприятия используют различные методы сушки, зачастую многие из них менее эффективны. Для решения этих проблем в данной статье предлагается применять синтетический эфир в сухом распределительном трансформаторе. Для исследования была использована усовершенствованная экспериментальная модель изоляции трансформатора. С помощью этой модели осуществлялась сушка сложного эфира с помощью молекулярного фильтра и тщательно отбиралась адсорбированная масса. Содержание воды в полосах прессованного картона до и после сушки анализировали для определения эффективности сушки целлюлозной изоляции. Содержание воды определялась методом титрования Карла Фишера. При уровне влажности эфира 105-120 ppm и температуре системы изоляции 70 градусов образцы, прошедшие сушку в течение 5 дней, показали потерю воды выше 1%. Эксперименты исследования были проверены на силовых распределительных трансформаторах.

We present an analysis of the JWST NIRCam and MIRI morphological properties of 80 massive ($\log_{10}(M_\ast[M_{\odot}])$=11.2$\pm$0.1) dusty star-forming galaxies at $z$$=$2.7$^{+1.2}_{-0.7}$, identified as sub-millimetre galaxies (SMGs) by ALMA, that have been observed as part of the JWST PRIMER project. To compare the structure of these massive, active galaxies to more typical less actively star-forming galaxies, we define two comparison samples. The first of 850 field galaxies matched in specific star-formation rate and redshift and the second of 80 field galaxies matched in stellar mass. We identify 20$\pm$5% of the SMGs as candidate late-stage major mergers, a further 40$\pm$10% as potential minor mergers and 40$\pm$10% which have comparatively undisturbed disk-like morphologies, with no obvious massive neighbours. These rates are comparable to those for the field samples and indicate that the majority of the sub-millimetre-detected galaxies are not late-stage major mergers, but have interaction rates similar to the less-active population at $z$$\sim$2-3. We establish that SMGs have comparable near-infrared sizes to the less active populations, but exhibit lower S\'ersic indices, consistent with bulge-less disks and have more structured morphologies at 2$\mu$m relative to 4$\mu$m. We find evidence for dust reddening as the origin of the morphological differences between the populations, identifying a strong correlation between the F200W$-$F444W pixel colour and the 870$\mu$m surface brightness. We conclude that SMGs and less active galaxies at the same epochs share a common disk-like structure, but the weaker bulge components of the SMGs results in a lower dynamical stability. Consequently, instabilities triggered either secularly or by minor external perturbations result in higher levels of activity (and dust content) in SMGs compared to typical star-forming galaxies.

Abstract As the fourth staple food crop in the world, potatoes can provide enough energy, protein, and nutrients necessary for humans. However, the population growth and negative effects of climate change call for improved potato yields and resilience. Genetic engineering is a convenient way to improve potato varieties and create new germplasm resources. Agrobacterium tumefaciens mediated transformation is a stable and widely used method for genetic improvement. In this study, a simple and efficient transgenic system was built by testing different potato materials, explants type, selection medium, selection agent, A. tumefaciens EHA105 strain carried different vectors. The results shown this simple system produced positive transformed seedlings in about 40 days. The lower ploidy change ratio for tetraploid variety Desiree compared to diploid recipient. Both SEG and SE could function as a single regeneration medium. Leaf discs explants is eligible. The concentration of 20μg/L is suitable for chlorsulfuron selection. The positive transgenic efficiency of tetraploid recipient Desiree is up to 68.79%, This simple and fast transgenic system provides a powerful tool for supporting basic research on potato functional genes and creating new potato materials for genetic engineering breeding.

To systematically review long-term (> 5years) outcomes of ESP surgery for OSA treatment over 17years. Systemic review of MEDLINE, Google Scholar, Cochrane Library and Evidence Based Medicine Reviews to identify publications relevant to OSA and Expansion Pharyngoplasty and its variants. All relevant studies published between January 2007 and June 2023 were included. Twelve studies were included in this systematic review with a combined total of 1373 patients who had the ESP procedure were included. The clinical outcomes included encouraging long-term success rate, reductions in Epworth sleepiness scale, good mean disease alleviation, anatomical structural area and volume improvements, blood pressure reductions, biochemical improvements in acute phase reactants after ESP surgery, reductions in intra-ocular pressures, and post-operative reduction of sympathetic overdrive. Seventeen years on, the expansion sphincter pharyngoplasty has demonstrated not only increase in anatomical area and volume but significant desired improvements in polysomnographic, clinical and biochemical parameters post-surgery.

Project Background: The project ‘Assessing Best Practices of Impact Based Alerting’ takes a case study approach to assessing the progress that is being made towards implementation of an impact-based paradigm for hydrometeorological warnings in both Europe and Asia. National Meteorological and Hydrological Service (NMHS) agencies around the world have been strongly encouraged by the World Meteorological Organization (WMO) to transition their alerting programs from hazard-based to impact-based warnings (IBW). This is happening in the context of the Sendai Framework 2015-2030. Currently, at roughly the halfway point to the conclusion of the Sendai Framework, this project performs a ‘check-in’ on the progress of this transition at NMHSs and affiliated partners in both Europe and Asia. This investigation also comes in the wake of recent, high-profile flooding and extreme heat events in both Europe and Asia. The increasing frequency of extreme weather events due to climate change increases the need for a clear understanding of the requirements and obstacles for NMHS agencies as they transition to an IBW approach. EMS presentation: At EMS 2023, we will present the findings of interviews conducted at NMHSs and associated key stakeholders, investigating the transition process to IBW in the UK, Sweden and Belgium in Europe and also Bhutan and Nepal in Asia. These findings contribute to a final project report (currently being developed as of April 2023). This report will be operationally relevant, speaking directly to NMHS agencies, key stakeholders (utilities, transport operators, health care practitioners, emergency management officers, etc.) and engaged members of the public alike. The focus will be on lessons learned and best practices from agencies who have already made the transition, while identifying concerns or roadblocks that may be holding back organisations who have yet to make the transition to IBW from doing so. The report will function as a tangible, relevant ‘handbook’ helping all NMHS agencies take the necessary steps, in their own national contexts, towards meeting the WMO recommendation.

In this paper, 1 I am going to explore the question whether social relations of "strong asymmetrical dependency" can be identified during the earliest historical periods of ancient China: the late Shng (ca. 1300-ca. 1045 BC) and Western Zhu (ca. 1045-771 BC). Although many cultural, social, paleographic, and linguistic features of later "China" originate in them, and important social and political processes beginning under the Western Zhu eventually led to the formation of the Chinese empire in 221 BC, society in these periods differs to some extent from that of later periods. I will therefore look for examples of "strong asymmetrical dependency" in epigraphic sources, paying particular attention to designations of social groups. This entails, in a first step, a re-evaluation of previous scholarship regarding the presumed existence of "slaves" in early Chinese antiquity, because ancient China often has been regarded as a so-called "slave society" in certain historical stages, thus problematizing the usage of later social terminology for far earlier social phenomena. 2 In a second step, I am going to look at possible cases of "strong asymmetrical dependency" in ancient inscribed texts: How can they be identified? And finally, I shall consider alternative I am very grateful to Maxim Korolkov for valuable comments on this paper that helped to improve it, and to Chai Jianhong, John Gillingham, Matthias Richter, Anne Sapich, Christian Schwer-

Abstract In 2021, unconstitutional transfers of power in Myanmar and Afghanistan highlighted that while States may desire a coherent response to questions about the status of governments, and may look for international guidance in such regard, there is no established process for providing such guidance. Thus, attention focuses on the General Assembly's credentials process, designed to assess the eligibility of delegates to represent their States at the UN. This article proposes that rather than the credentials process being stretched in this way, greater use should be made of the Assembly's competence to pass determinative resolutions on government legitimacy.

The agrifood value chain has multiple stakeholders involved in all stages from production to post waste management. They range from private companies’ decision makers with a stake in the production and delivery processes, to workers and their communities, to consumers, to policy makers, to researchers and scholars. Reducing the impacts of the value chain requires that these stakeholders develop a common understanding and co-participate complex decision-making processes which include trade-offs. To do so, they need approaches that can capture and integrate the different points of view and allow them to interact with each other on common ground and reach consensual decisions. In the chapter we present a bottom-up participatory collaborative approach to mapping the value chain from raw materials to post waste management and its interactions with the ecosystem’ services which has been successfully tested on different segments of the agrifood value chain. The approach, called ALCHEMY (a participatory coLlaborative approaCh to mapping the interactions between value cHain, the EnvironMent and societY), captures the perspectives of the many stakeholders, i.e. business decision makers, policy makers, communities, researchers through the use of standardised iteratively updated maps. Through the maps the stakeholders build shared future lower impact scenarios, where environmental management interventions are agreed and the evaluation of environmental benefits is consensual. The maps can be used by all stakeholders for monitoring, reporting and evaluation on the progress of the interventions, and for co-creation of solutions. The approach has been successfully applied to co-design potential solutions to the consumer segment impact-reduction problem and the circular economy focused end-of-life post-consumer waste problem. ALCHEMY could be of help for policy makers, decision makers in enterprises, communities that depend on the value chain, advocacy organisations and the academic community to develop real world low impact low waste solutions.
