Experimental Study and Numerical Simulation of the Water Entry of a Ship-Like Symmetry Section with an Obvious Bulbous Bow
Authors: Wang Qiang , Yu Pengyao , Zhang Boran , Li Guangzhao 
Published: October 2021

Abstract
A bulbous bow is a typical ship structure. Due to the influence of the bulbous bow, complex flow separation and gas capture phenomena may appear during the water entry of ship-like sections. In this paper, experimental and numerical studies on the water entry of a ship-like section with an obvious bulbous bow are carried out. Two thin plates are installed at both ends of the test model to ensure that the flow field during the impact process is approximately two-dimensional. The free-fall drop test is carried out in the test rig equipped with guide rails. By changing drop heights, impact pressure on the model surface with different initial impact velocities is measured. A numerical model for simulating the water entry of the ship-like section is established by using the Computational Fluid Dynamics (CFD) method, based on the Navier-Stokes equations. Reasonable time steps and mesh size are determined by convergence analysis. Four different flow models are used in the numerical analysis. It is found that the K-Epsilon turbulence model can present the most reasonable numerical prediction by comparing numerical results with the experimental data. Furthermore, the influence of the bulbous bow on the impact loads is numerically studied by using the validated numerical model. It suggests that the bulbous bow has little effect on the impact force acting on the bow-flared area but, in the position near the bulbous bow, the pressure will be affected by the second slamming and the air cushion.

Abstract
Ensuring the safety of ship crews at sea is of the utmost importance. Life rafts are one of the basic components of any seagoing vessel and ensuring their stability is an important component of maritime research. This study concerns the determination of the aerodynamic drag coefficients of pneumatic life rafts in a full range of wind speed and directions. The drag coefficients are based on full-scale experimental studies and numerical calculations (computational fluid dynamics) carried out with Flow-3D software. Two types of life rafts are analysed in the numerical simulations, namely, a non-deformed raft and a raft deformed under the influence of wind pressure at a given flow velocity. The shape of the deformed pneumatic life raft is recreated on the basis of photographic documentation from experimental studies. The results of the numerical calculations are verified on the basis of full-scale flow experiments carried out at the Low Speed Wind Tunnel T-3 Laboratory at the Institute of Aviation in Warsaw. This study shows that there is a dependence of aerodynamic drag on the degree of deformation of the above-water part of the life raft, as well as the angle of the raft setting to the wind. In real water conditions, this angle depends mainly on the anchor point of the drift anchor and therefore should be considered at the design stage, which will directly reduce the wind leeway of the raft.

Abstract
Anaplastic gliomas compromise about 5.9% of primary CNS tumors. The main goal of the operation is the maximum removal of the tumor, reduction of the tumor mass and reduction of the increased intracranial pressure. Different pathohistological subtypes of anaplastic gliomas show significantly different prognosis depending on the applied oncological therapeutic protocol as well as the modality of the applied radiotherapy. The study was designed as a retrospective, clinical observational study. The study included 34 participants who were diagnosed with anaplastic glioma in the followed time period. Survival rates were calculated based on the localization, modality of therapy and complications. We concluded that 20,4% of anaplastic gliomas were formed by transformation from previously operated lower grade gliomas. The initial sign of the disease is the appearance of epileptic seizures. Anaplastic gliomas most oftenly occur in the frontal region, with a frequency of 47%. The incidence of anaplastic gliomas in the temporal lobe is 23,5%. The length of survival is in relation to the localization of tumor expansion(p<0.05). The overall survival in the group of anaplastic gliomas operated on in the Department of Neurooncology KCS in the follow-up period of five years is 52.9%. The application of different chemotherapy modalities is not significant predictor in the length of survival. The radical nature of the operation has significance in the length of patient survival, which confirms the conclusions of most of the conducted studies cited in oncology textbooks.

Le conflit des libertés
Authors: Girard Charles 
Published: October 2021

Le conflit des libertés constitue un problème redoutable pour toute théorie des droits fondamentaux, tant du point de vue de leur justification que de leur mise en œuvre. La théorie rawlsienne de la justice comme équité suggère une réponse originale, qui cherche à éviter tant la mise en balance des libertés que leur absolutisation rigide. Le système des libertés de base est strictement prioritaire par rapport à toute autre considération, mais les libertés elles-mêmes ne sont pas, prises individuellement, absolues : elles doivent être ajustées les unes aux autres pour former un système cohérent, où les contradictions sont évitées. Elles ne sont toutefois pas négociables, car cet ajustement doit les réguler sans les restreindre. L’article reconstruit et évalue cette réponse au conflit des libertés. Il montre qu’elle n’est convaincante que si l’on renonce à l’exigence rawlsienne d’une priorité absolue du système des libertés.
Quels principes de justice pour la famille ?
Authors: Bastin Marie 
Published: October 2021

Quels principes de justice pour la famille ? Rawls défend la thèse selon laquelle si la famille appartient bien à la structure de base de la société, sa vie interne doit être régulée par des principes de justice locale. À l’inverse, Okin soutient l’idée selon laquelle l’application directe des principes de la justice sociale à la vie interne des familles est nécessaire pour lutter contre les injustices de genre dont les femmes sont les principales victimes et assurer un bon développement moral des enfants. Nous défendons la thèse selon laquelle les questions de justice dans la famille, et notamment celles relatives au genre, peuvent être mieux saisies si l’on désagrège la famille en différentes institutions, auxquelles les principes de la justice sociale doivent, ou non, s’appliquer directement.
Désaccord raisonnable et démocratie
Authors: Roussin Juliette 
Published: October 2021

Peut-on justifier l’emploi de procédures démocratiques de décision en invoquant le désaccord irrémédiable qui existe entre les citoyen·nes sur les questions sociales, de justice et de droit ? Forgé par Rawls pour penser le statut des conceptions morales, philosophiques et religieuses dans une société libérale, le concept de « désaccord raisonnable » a été étendu par certain·es théoricien·nes de la démocratie, notamment Jeremy Waldron, pour englober toutes les questions politiques et juridiques. Cet article montre qu’une telle extension a des effets contre-productifs pour la justification de la démocratie. D’une part, elle aboutit à relativiser l’importance de la décision démocratique. D’autre part, elle fait paradoxalement apparaître le mode de décision démocratique comme injustifié.
Impact d’un an de Covid
Authors: Sliman Gaël 
Published: October 2021

La peur de la Covid, associée à l’envie des Français d’aider des soignants qu’ils jugent à la fois héroïques et débordés, a incité nos concitoyens à accepter longtemps sans rechigner des contraintes inédites sur leurs libertés individuelles. Mais l’usure du temps, et le poids de ces contraintes sur leur vie quotidienne, leurs revenus, et leur moral, conjugué à leur défiance à l’égard du gouvernement ont conduit les Français à être « à bout » en ce printemps 2021. Leur acceptation de la vaccination, après des mois de scepticisme, est de bon augure pour l’avenir, mais il faut espérer que l’épidémie se termine rapidement car ni l’état moral de la population ni sa grande défiance dans la politique sanitaire du gouvernement ne nous permettraient de faire face à un éventuel rebond (variant coriace) de l’épidémie au-delà de l’automne prochain.
Histoire d’une infiltration au sein de l’ETA : El Lobo de Miguel Courtois (2004)
Authors: Picod Claire 
Published: October 2021

Le film El Lobo (2004) de Miguel Courtois retrace l’histoire de l’infiltration au sein de l’ETA organisée par le SECED de Mikel Lejarza – dit « El Lobo » – à la fin de l’époque franquiste. Cette opération aboutira à un démantèlement partiel de l’ETA, marquant un succès notoire des services secrets. Au-delà du récit historique sont abordés les thèmes de la trahison et de la rivalité, à la fois à l’intérieur des services secrets et au sein même de l’ETA. Le scénariste s’affranchit de toute vision manichéenne, en traitant de façon originale la thématique du terrorisme. C’est enfin l’histoire d’un homme seul, à la fois trahi et abandonné par les siens, lequel ne trouvera de refuge qu’en changeant d’identité…
Un lieu polémique : Versailles dans les manuels d’enseignement primaire de la IIIe République
Authors: Sabatier Gérard 
Published: October 2021

Fleuron du patrimoine français, Versailles fut longtemps un lieu polémique. Après la défaite de 1870, les républicains travaillèrent à élaborer un récit national diffusé par les manuels officiels de l’enseignement primaire, dont l’usage fut obligatoire. Un des problèmes fut d’exalter les œuvres de la nation tout en minorant voire discréditant l’action des gouvernants. Comment parler de façon élogieuse d’un roi en République ? Comment faire l’éloge du Grand Siècle et discréditer le Grand Roi ? Versailles fut l’enjeu de cette posture contradictoire. Face brillante de la France, face noire de Louis XIV, théâtre où se produisent tous les talents de la France, instrument de mégalomanie d’un tyran et ruine des Français. Cette présentation caricaturale de Versailles s’estompe dans les manuels alors que le climat politique change. La place des textes se réduit au profit d’une iconographie plus soucieuse d’exactitude. La découverte de Versailles s’opère dans les années 1930 et surtout après-guerre, s’inscrivant dans la politique de patrimonialisation d’une nation en quête de soft power.

Authors: Tran Luan Viet , Duong Vu Anh , Lokman Saim 
Published: October 2021

Objective:
The aim of this study is to determine the prevalence of the inner ear malformations (IEMs) in cochlear implant recipients according to Sennaroglu's classification, and to document the intraoperative difficulties and complications in those cases.

Methods:
This was a descriptive cross-sectional study performed at our hospital between January 2016 and October 2019. IEMs on temporal bone computed tomography scans were identified in all patients who received cochlear implants during the study. Intraoperative difficulties and complications relating to these malformations were described.

Results:
Twelve patients with IEMs were identified from a total of 212 cochlear implant recipients, representing a prevalence of 5.7%. Among them, one patient with incomplete partition (IP) Type I (8.3%), seven patients with IP Type II (58.3%), one patient with IP Type III (8.3%), one patient with cochlear hypoplasia (CH) Type I (8.3%), and two patients with CH Type III (16.7%) were identified. Associated enlarged vestibular aqueduct was found in four cases with IP Type II (33.3%). Round windows were not identified intraoperatively in 3 cases with CH (25%). Three cases (25%) had cerebrospinal fluid gusher (one patient in each of the following anomalies: IP-I, IP-II, and IP-III). The mean categories of auditory performance score was 6, which was collected within 23.3 months after the surgery.

Conclusion:
This study documents the prevalence of IEMs in cochlear implant recipients (classified by Sennaroglu in 2017). The identification of such anomalies will significantly aid surgeons in making decisions regarding cochlear implant candidacy and surgical strategy when cochlear implantation is contemplated to obtain optimal outcomes.
Lúpus de início tardio
Authors: Reis Neto Edgard Torres dos 
Published: October 2021

O lúpus eritematoso sistêmico (LES) é uma doença inflamatória crônica autoimune que pode acometer diversos órgãos e sistemas. Tem incidência variável, com 3,8 casos/100.000 habitantes na Inglaterra e 7,8/100.000 habitantes no Brasil. Com a melhora no diagnóstico e tratamento da doença nos últimos anos, além do aumento da sobrevida dos pacientes, tem-se observado cada vez mais frequentemente o surgimento de complicações decorrentes da doença ou de seu próprio tratamento, sendo o LES encarado como uma doença crônica.
Embora a Organização Mundial da Saúde (OMS) defina idoso como todo indivíduo com idade maior ou igual a 60 anos, para a formulação de políticas públicas, o limite de idade pode variar de acordo com o país. É importante frisar que, seja qual for o limite mínimo adotado, faz-se necessário considerar que a idade cronológica não é um marcador preciso para as alterações que acompanham o envelhecimento, podendo haver grandes variações quanto a condições de saúde, nível de participação na sociedade e de independência entre as pessoas idosas em diferentes contextos. Descreveremos, a seguir, as principais características do lúpus de início tardio, com relação a sua epidemiologia, manifestações clínicas e tratamento. Na maioria dos estudos acerca do LES de início tardio ou lúpus de início no idoso, a idade adotada foi maior ou igual a 50 anos.

EFFECTS OF LONG-TERM ADMINISTRATION OF COOKED BEANS (Vigna unguiculata) DIET ON LEARNING AND MEMORY IN MICE
Authors: Aduema W. 
Published: October 2021

Purpose: The neurotransmitter, serotonin has neurobehavioural actions which include mood, memory, learning and sleep. Beans, the stable diet of Nigerians contains serotonin and its precursor, 5-Hydroxytryptophan in significant amounts. It was therefore the aim of this study to find out whether long term consumption of cooked beans (Vigna unguiculata) diet has effects on some neurobehavioural parameters notably; learning and memory, using Swiss white mice as experimental animals.Method: Thirty (30) CD1 mice were randomly assigned into three groups, viz; (10, control, 20 Test) weighing 15-30g were fed normal rodent chow, 50% cooked beans diet (w/w) respectively and serotonin precursor (5-HTP) diet (0.2mg/50g w/w) for thirty days. All the mice had access to clean drinking water ad libitum. Before the neurobehavioural parameters were assessed, the phytochemical analysis of the beans, LD50 of the beans (Vigna unguiculata) and that of the serotonin precursor (5-HTP) were determined. Serotonin concentration was measured in the beans using gas chromatography analysis. Learning and memory, was investigated alongside food and water intake and body weight change. Involvement of serotonin pathway was investigated using the set of mice administered serotonin precursor for comparison with the beans diet fed mice. Mice were tested in the Morris water maze for 8 days: 3 days of acquisition training, 3 days of reversal training, 1 day of single probe trial and 1 day for visible platform task.Results: Learning on days 1, 2 & 3 of acquisition training was improved in the cooked beans and serotonin precursor diet-fed mice when compared to control (p<0.001, respectively). The trend was similar during the reversal training, memory was improved in the beans and serotonin precursor diet-fed mice when compared to control (p<0.001). During the probe trial, the swim duration in the South-East quadrant was significantly higher for cooked beans and serotonin precursor group compared to control (p<0.05). However, during the visible platform task, the swim latencies for the cooked beans and serotonin precursor group was significantly lower compared to control. Our finding therefore suggests that long term consumption of beans diet enhances learning and memory. Conclusion and Recommendation: In conclusion, long term consumption of cooked beans diet enhances learning and memory. If this research can be extrapolated to humans, we recommend that the serotonergic potential of beans may be harnessed in the prevention, treatment and management of behaviour/ mental disorders as this could potentially open up a vista for improved mental health status in populations globally.
Photonic Janus Carbon Fibers with Structural Color Gradient for Multicolored, Wirelessly Wearable Thermal Management Devices

Published: October 2021

AbstractJanus structure offers materials unique functionalities which are difficult to achieve otherwise with isotropic counterpart, opening up new avenues in diverse application fields. Here, a series of novel photonic Janus carbon fibers (PJCFs) with structural color gradient and excellent mechanical stability are reported by introducing 1D photonic layers with a gradient of periodicity. By virtue of the unique photonic architecture, the PJCFs exhibit a multiple and continuous variation of structural color (i.e., structural color gradient) in a full spectrum. By controlling the thickness of periodic layer, a series of PJCFs with vivid and tunable structural colors ranging from blue, green, orange, to violet‐red can be obtained. Furthermore, their gradient structural colors remain constant after reciprocating rubbing and laundering, showing outstanding mechanical robustness. Notably, benefiting from the inherent electrothermal property and flexibility of CFs, the PJCFs display stable Joule heating performance even under deformation. As proof‐of‐concept, the PJCFs are further integrated with wireless transmission system to construct a multicolored, wirelessly controlled thermal management device, realizing remote and precise temperature manipulation via Bluetooth. This work provides not only a new platform for achieving distinct structural color gradient of CFs, but also a promising strategy toward next‐generation multicolored personal healthcare devices.
