Background:The broodstock diet,and in particular the lipid and fatty acid composition of the diet,is known to play a key role in reproductive efficiency and survival of the progeny in fish.A major problem when replacing both fish meal and fish oil by plant sources is the lack of n-3 long chain polyunsaturated fatty acids,such as eicosapentaenoic acid(EPA)and docosahexaenoic acid(DHA).To address this problem,we studied the effect of the plant-based diet supplemented with Schizochytrium ***,source of DHA,compared to a conventional commercial diet rich in fish meal and fish oil on reproductive performance and egg quality and the consequences on progeny,in female rainbow trout ***:The results demonstrated that DHA-rich microalgae supplementation in a plant-based diet allowed for the maintenance of reproductive performance and egg quality comparable to a conventional commercial feed rich in fish meal and fish oil and led to an increased significant fry survival after ***,when females were fed a plant-based diet supplemented with micro-algae,the 4-month-old progenies showed a significant higher growth when they were challenged with a similar diet as broodstock during 1 *** provide evidence for metabolic programming in which the maternal dietary induced significant protracted effects on lipid metabolism of ***:The present study demonstrates that supplementation of a plant-based diet with DHA-rich microalgae can be an effective alternative to fish meal and fish oil in rainbow trout broodstock aquafeed.

Nozzle wall ablation caused by high temperature electric arcs is studied in the context of high voltage SF6 circuit breakers. The simplified ablation model used in litterature has been updated to take into account the unsteady state of ablation. Ablation rate and velocity are now calculated by a kinetic model using two layers of transition, between the bulk plasma and the ablating wall. The first layer （Knudsen layer）, right by the wall, is a kinetic layer of a few mean-free path of thickness. The second layer is collision dominated and makes the transition between the kinetic layer and the plasma bulk. With this new coupled algorithm, it is now possible to calculate the temperature distribution inside the wall, as well as more accurate ablation rates.

Cooperation among service providers, network providers, and access providers in the Internet allows the creation of new services to offer to customers that are in other domains, thus increasing revenue. However, the Internet heterogeneous environment, where each provider has its own policies, infrastructure and business goals, hinders the deployment of more advanced communication services. This paper presents a Quality of Service （QoS） for Inter-Domain Services （QIDS） model that allows inter-domain QoS-aware services to be defined, configured, and adapted in a dynamic and on-demand fashion, among service providers. This is accomplished by： 1） the use of a common communication channel （business layer） where service providers publish and search for services, and interact with each other to contract and manage these services; 2） the templates to specify the business and technical characteristics of the services; 3） the automatic composition of services using service dements （smaller services） a^cording to performance and service-specific QoS parameters; and 4） the creation and enforcement of configuration rules for the underlying infrastructure. A prototype was implemented to validate QIDS and performance tests were conducted on an inter-domain Border Gateway Protocol （BGP）/Multiprotocol Label Switching （MPLS） Virtual Private Network （VPN） scenario.

Background: Extracranial Carotid Artery Aneurysm is considered a therapeutic and diagnostic challenge. In an unprecedented way in the literature, we describe an aneurysm originating from the Catastrophic Antiphospholipid Syndrome. Case Presentation: A 25-year-old male patient came to the Emergency Room of the ABC University Hospital in Sao Bernardo do Campo referring to bilateral neck pain for 1 month, associated with carotid aneurysms. Due to the severity and urgency of the clinical condition, immediate surgical therapy was performed without a definitive etiological diagnosis. The initial morphological analysis of the carotid artery suggested a diagnosis of Polyarteritis Nodosa. After anamnesis, physical examination, the use of a specific primary vasculitis algorithm, and a review of the pathological anatomy was requested, which showed bilateral carotid aneurysms secondary to catastrophic antiphosp

洞穴是喀斯特景观中普遍存在的地质地貌结构,拥有丰富的植物资源。仅2001–2020年间,就发表了中国喀斯特洞穴维管植物新属1个;新种(含种下等级)170个,隶属于16科31属,占近20年发表的中国维管植物新种的3.9%,说明洞穴植物具有较高的物种多样性潜力。据统计,中国喀斯特洞穴维管植物有110科339属871种,主要分布于广西、广东、贵州、云南、重庆等地。物种数排名前5的科包括苦苣苔科、荨麻科、鳞毛蕨科、秋海棠科和茜草科,其所含物种数共占整个洞穴植物种类的39.4%;排名前5的属包括报春苣苔属(Primulina)、楼梯草属(Elatostema)、耳蕨属(Polystichum)、秋海棠属(Begonia)和凤尾蕨属(Pteris),其所含物种数共占整个洞穴植物种类的25.1%。本名录的所有洞穴植物中,草本习性的种类占一半以上。从洞内分布来看,仅有10.7%的种类分布于弱光带,其中石松类和蕨类植物占比远高于被子植物,说明前者更能适应弱光带的极端环境。不仅如此,洞穴维管植物也具有较高的特有性成分,其中省级特有种占比25.8%,分别包括非洞穴特有种(11.0%)、多洞穴特有种(3.3%)和单洞穴特有种(11.5%)。依据文献显示受威胁种类有115种(占13.0%)。受威胁种类占比较高的类群均是近年来发表新种较多的科,包括鳞毛蕨科、苦苣苔科、荨麻科、秋海棠科、茜草科等。针对这些类群,有待更详细地调查来完善对它们的评估。此外,本名录中至少有36%的种类没有任何分子数据,亟待补充。
