We investigate attenuation scattering and loss properties in Souss basin(SW of High-Atlas) as a transition zone between the High and Anti Atlas ranges. This district consists in a thinned crustal patch with shallow seismicity and loose sedimentary trenches that perform an important contribution to augment seismic attenuation. So far, no coda waves approach in our knowledge have been used to draw satisfying outputs about the attenuation properties in the region. Therefore, this update suggests to correlate the lateral changes of seismic attenuation to different characteristics and asperities i.e. seismic activity,crustal age and thickness, heat flow, and ground deformation rate. To do so, we analysed coda waves derived from waveform data of more than 23 local earthquakes from seven broadband seismometers recorded during 2010 e2012 period. As a starter, we utilized the backscattering model which defines theseismic attenuation as inversely proportional to quality factor by the equation A ?1=. QQcestimates c were deducted at various central frequency bands 1.5, 3.0, 6.0, 9.0, 12.0 and 18.0 Hz according to different lapses times. The estimated average frequency dependence quality factor gives relation Qc? 120 f1;01,while the average Qcvalues vary from 149 at 1.5 Hz to 1895 at 18 Hz central frequencies. We observed an intimate dependence between quality factor and frequency ranges, which reflects the complexity of geological/geophysical pattern in the Souss basin and the presence of a variety of heterogeneities within the underlying crust.

过去两年来,非洲大陆各国熟练地实现了闻所未闻的增长。但是,能源作为金融、政治和社会发展的一个重要支柱,仍然是它们面临的重大困难之一。事实上,非洲国家的公众面临着电力进入的巨大损失。在矿物燃料继续主导其能源组合的同时,这些国家拥有丰富的可再生能源,可使电力负担得起、可靠和可持续。近年来,非洲的可再生力量部署战略赢得了势头,走向了多种因素的结合,其中包括动态货币爱好、民众快速增长和技术能源收费下降。以及可再生电力技术量的下降。然而,非洲和摩洛哥选择在能源问题上实行善政;即将其经济和社会发展与保护环境相结合。因此,本研究旨在强调自发展可再生能源以来发生的变化及其对受益区域的发展在社会经济层面和环境保护方面的影响。目的是评估上述能源战略对非洲大陆可持续发展的贡献。对可再生能源作为满足这一需求同时也应对气候变化的一种方式的兴趣日益浓厚,这是非洲和中国能源需求不断增长的结果。本文着眼于摩洛哥的桉例研究,探讨了非洲与中国在可再生能源背景下的相互作用。该研究采用定性和定量研究方法,研究了中国企业参与摩洛哥可再生能源发展的情况以及这一发展对国家经济和社会的影响。根据这项研究,中国企业对摩洛哥可再生能源的增长作出了重大贡献,特别是在太阳能行业。这项研究通过采访中国重要太阳能公司Jinko Solar的员工,分析了可持续性做法及其对邻里的影响。这项研究还采用一种比较方法来探讨摩洛哥作为可持续发展和可再生能源区域领导者的地位。本文提供了中国与非洲在可再生能源领域合作动态的深刻信息,以及这种合作对摩洛哥等国的可能利弊。更广泛地研究非中互动的研究人员应该注意到这项研究对可再生能源行业决策者和从业人员的重大影响。这项研究也可作为今后相关研究的有用信息来源。

学生参与度被认为是学生在高等教育机构体验质量的一个基本标准和指标。本研究采用混合研究方法,调查了在浙江师范大学、武汉大学、法学院、华中大学和丽水学院学习的,来自40个国家的国际学生的学习参与情况,以确定COVID-19对他们在疫情期间可能遇到的不同挑战的影响,并研究了中国高等教育机构采取的措施。定量数据是在2021年7月18日至8月18日期间从149名参与在线调查的国际学生中收集的。定性数据来自于2021年12月21日至25日对8名国际学生的采访。这项研究的相关性是由COVID-19下国际学生参与的实际问题决定的。这些学生透露了他们在认知、行为和情感参与方面遇到的各种障碍。量化研究结果显示,在全球封锁和向在线学习过渡的过程中,国际学生对其效率不满意,但结果没有受到影响,即使有COVID-19,他们依然有兴趣继续攻读学位。他们最满意的是高等教育机构在疫情期间所扮演的角色。由于疫情导致采取了特定的防疫措施。因此,目前的研究结果与了解如何支持学生成功克服文化冲击的困难环境的有效措施有关,包括家庭支持、汉语学习和寻找相同国籍的朋友。此外,调查结果还显示,各大学通过提供灵活的学费支付方式来帮助国际学生,而奖学金的价值保持不变。同样,结果表明,他们有能力接受中国为抗击COVID-19而施加的限制。我们的研究结果表明,新冠肺炎疫情对留学生的心理健康、教育和日常生活参与产生了显著影响。此外,研究结果也显示了汉语在留学生日常生活中的重要性,一些学生描述了疫情期间他们发生的巨大变化,特别是与中国学生在课堂内外的交流问题。即使有冠状病毒,国际学生还是决定留下来继续学业。然而,他们主要关心与他们的经济状况和学习有关的问题,并经历了无聊、焦虑和抑郁。此外,从定性数据的分析中,出现了三个突出的主题。三个主题分别是:1)国际学生在线学习的认知参与;2)国际金融行为的潜在影响;3)疫情期间的情感参与;4)新冠肺炎期间学生参与度的文化冲击。国际学生对在线教育的重视程度低于线下教育,他们的积极性和参与感较低,他们花在学习上的时间也较少。积极性的下降可能与完成任务的时间过晚以及对在线学习缺乏关注有关。然而,结果表明,大多数参与者深入参与在线课堂讨论,并与他们的同学合作。让学生感到深深的投入的主要原因是有帮助和鼓励他们的老师,因此国际学生对他们和他们的同学表达了积极的反应。与此同时,大多数面临经济问题的国际学生在情感生活和个人情况方面普遍受到疫情的影响更大。本研究的目的是通过混合方法了解冠状病毒的影响,重点是关于新冠疫情大流行背景下中国大学里国际学生真实的日常情况的实用知识。此外,关注这些问题将为国际学生提供更适当的支持。本文为高等教育教育者、国际学生和研究人员提供了未来研究的建议和启示,因为本研究的启示是重要的,因为它有可能影响学习投入。

Hereditary hemochromatosis is a condition characterized by iron overload, which is both treatable and preventable. It’s mainly related to hepcidin deficiency related to mutations in genes involved in hepcidin regulation. Iron overload increases the risk of disease such as liver cirrhosis, heart disease and diabetes. Two HFE genotypes have been commonly described in cases of iron overload, C282Y homozygosity and C282Y/H63D compound heterozygoty. The diagnosis of this rare disease now can be explored by biological and imaging tools. We report a case of compound heterozygous C282Y/H63D discovered by family screening for elevated serum ferritin.

Aim: The goal is to simulate different stages of the endovascular procedure in the preoperative phase. Methods: We have developed a numerical model of the endovascular treatment of abdominal aortic aneurysms (AAA) using finite element analysis (FEA), we took into account the geometry of the biological region reconstructed from scans, a local characterization of the guidewire/catheter mechanical properties, a mapping of material properties depending on the degree of calcification, a real behavior of the vascular walls, and a projection of the aorta environment. Results: Our results present the endovascular system navigation from the femoral artery to the neck of the aneurysm, predict the deformation of femoral, iliac and aortic arteries while driving flexible and stiff endovascular devices, and detect stress concentration due to tortuous and calcified artery zones. A given group of patients with very angulated and calcified arteries were validated, based on a tuning between clinical data and our endovascular simulation. Conclusion: Our model allows controlling with accuracy the delivery system rise during surgery, predicting the feasibility of the surgery with reliability as well as choose the best guide for each patient, taking into account the risk of rupture of calcified areas in the case of high angulations, and using planning simulated images with deformation of artery walls to propose stent sizing.

Bluetongue （BT） is an infectious, non-contagious arthropod-borne disease that infects all ruminants, including sheep, cattle, deer, goats and camelids. Bluetongue virus （BTV） belonged to Reoviridae is ARN genome of 19 Kb. Twenty-six BTV serotypes have long been recognized, to be associated with severe disease in certain breeds of sheep, whereas cattle and goats are usually sub-clinically affected. Before 2004, BT was considered an exotic disease in Morocco, however, the first outbreak was observed in 2004 in sheep. This outbreak was caused by the isolated BTV-4. Two years later a BTV-1 emerged in Morocco. Both serotype 1 and serotype 4 circulated after 2007 across the country. The aims of the present work was to perform a serological study on sheep from different regions in Morocco in order to clarify the current BTV epidemiological situation and its evolution from 2009 to 2012, to determine the co-infection rate, and to confirm the possible circulation of other BTV Serotype mainly the BTV-8. All of 436 sera were tested by serum neutralization using reference strains. Results confirm the presence of BTV-4, BTV-1 and BTV-8. However, the present study report for the first time the emerging BTV-8 circulation in Morocco. Moreover, the founding reveal as well a higher co-infection rate in cattle compared to sheep.
