The World Health Organization declared Coronavirus disease 2019(COVID-19)a public health emergency of international concern(PHEIC)[1].Severe acute respiratory syndrome coronavirus 2(SARS-CoV-2),the etiological agent of COVID-19,is an enveloped,single-stranded,positive-sense RNA *** severe acute respiratory syndrome coronavirus(SARS)and Middle East respiratory syndrome(MERS),the causative agent of COVID-19belongs to theβ-genus of the coronavirus family and has a genome sequence with an 82%similarity to that of SARS[1,2].Therefore,research on human coronaviruses,especially SARS-CoV and MERS-CoV,could be useful for predicting likely environmental fate and subsequent risks of SARS-CoV-2[1].

A novel photocatalyst based on TiO2-PANI composite supported on small pieces of cork has been reported. It was prepared by simple impregnation method of the polyaniline（PANI）-modified TiO2 on cork. The TiO2-PANI/Cork catalyst shows the unique feature of floating on the water surface. The as-synthesized catalyst was characterized by X-ray diffraction（XRD）,scanning electron micrograph（SEM）, transmission electron microscopy（TEM）, thermogravimetric analysis（TGA）, Fourier transform infrared spectroscopy（FT-IR）, UV-vis diffuse reflectance spectra（UV-vis DRS） and the Brunauer-Emmett-Teller（BET） surface area analysis. Characterization suggested the formation of anatase highly dispersed on the cork surface. The prepared floating photocatalyst showed high efficiency for the degradation of methyl orange dye and other organic pollutants under solar irradiation and constrained conditions, i.e., no-stirring and no-oxygenation. The TiO2-PANI/Cork floating photocatalyst can be reused for at least four consecutive times without significant decrease of the degradation efficiency.

The architecture of the Ouargla Ksar has long been recognized as an example of adaptation to harsh climate in the deep desert of AlgeHao Over the last few decades, it has undergone some changes in its initial urban structure, due to accelerated and uncontrolled modern urbanization, that had negative implications and devaluation of its thermal characteristics. This article tries to understand the bioclimatic concept of adaptation of this Ksar and assess to what extent its morphological transformation has impacted its microclimatic conditions. This assessment is made through a comparative study between two different areas： one untransformed and the other transformed. A referential weather station situated in the suburbs was also exploited for consolidation of comparison. The investigation was undertaken using site measurements and observations.

A new case of epithelioid hemangioendothelioma is reported to have occurred to a 67-year-old patient who consulted for rightsided chest pain. The work-up showed multiple right pulmonary lesions associated with bilateral moderate pleural effusion and left-sided pleural thickening and three hypodense nodules in the right lobe of the liver, peritoneal thickening, ascites, and multiple vertebral lytic lesions. The diagnosis of an epithelioid hemangioendothelioma was concluded through a histological examination of a computed tomography scan guided biopsy of the liver. The patient received a primary mono-chemotherapy with Adriamycin(75 mg/m^2 every three weeks) and intravenous bisphosphonates without response and general status impairment. The patient died after 16 months of follow-up.

实时视频流应用系统,如可视电话、远程教育和视频会议,在未来的生活中有着重要作用。同时,应用层组播（ALM）是目前视频流技术非常重要的基础。上述两个方而仍面临诸多挑战,因此研究基于ALM的多媒体传输应用系统有重要意义。本文提出了一个基于ALM的视频会议系统设计。在功能上,本实时视频组播系统分为以下四个模块：视频采集模块、传输模块、服务器模块。系统采用混合P2P覆盖网组播树结构,减少了延迟和源端的压力,网路负载也得到平衡。为了提高视频的实时性,充当服务器的节点只负责管理成员关系信息,它负责应用层组播树的建立和维护。本文还提出了一个基于度约束的组播树算法设计,不仅考虑了带宽因素,还考虑了成员节点的计算能力。此外,为了提高组播效率,系统还使用了多线程技术和完成端口模型。由于视频捕捉模块中的相关技术比较成熟,考虑到在Windows环境下开发的需要,我们选择了Windows VFW作为视频技术平台。由于ALM的不稳定性,我们使用H.263标准作为视频编码,这是一种为低速率通信而设计的ITU-T标准。从分布式架构上看,系统由三部分组成：服务器、视频源和客户端。服务器只包括成员关系信息管理模块,而源端包括视频采集模块、编码模块和传输模块。客户端主要由传输模块和解码模块组成。这是一个计算机网络和多媒体技术的集成系统,有一定的实用价值。
