Objective: To assess the antioxidant content, antimicrobial and antioxidant activities of various propolis samples. Methods: Seven propolis samples were collected from different locations in Morocco, which are characterized by different plant predominant vegetations. The resin, wax and balsam of hydroalcoholic extract of propolis content were identified, and the antioxidant content was analyzed with the use of HPLC and colorimetric methods. The antioxidant activity was assessed by DPPH, ABTS.^+ and ferric reducing power assays. The antimicrobial activity was assessed against bacterial species, including methicillin resistant Staphylococcus aureus and Candida albicans, and expressed as the minimal inhibitory concentration. Results: The propolis samples showed significant variations in the chemical composition and in the antioxidant or antimicrobial activities even when the samples were collected from the same location. Propolis with high resin and low wax content had high level of antioxidant compounds, and strong antioxidant and antimicrobial activities. Gram-positive bacteria, especially, methicillin resistant Staphylococcus aureus were more sensitive to all propolis samples than Gram-negative bacteria and Candida albicans. Conclusions: The chemical composition and the antioxidant and antimicrobial activities of various propolis samples are different and rely on the geographic and plant origin of propolis collection. Propolis samples with low wax and high resin content might be more suitable to be used in future preclinical or clinical investigations.

在过去的十年里,印尼遭受了几次地震和海啸的袭击,造成了巨大的损失和人员伤亡。其中之一是亚齐省。自2004年亚齐海啸灾害以来,公众对灾害的认识开始增加,但这种认识还没有成为将他们的生活与灾害联系起来的态度、行为和文化。因此,亚齐气象、气候和地球物理局(BMKG)作为有义务提供早期预警的机构,必须有一个强有力的战略,以便早期预警能够为社会各阶层所接受。同样,媒体作为BMKG的伙伴机构,也必须发挥作用,以便能够方便地获得有关灾害预警和最新信息的公共信息。本研究提出的问题是,亚齐BMKG战略如何提供地震和海啸预警,亚齐BMKG的媒体传播策略如何在提供地震和海啸预警方面发挥合作伙伴的作用,以及社区如何见证BMKG亚齐及其媒体合作伙伴提供的地震和海啸预警信息。本研究采用质性研究方法,并透过观察、访谈等方式搜集资料。研究结果表明,亚齐BMKG有多个预警信息传递的辅助设施,最常用的是WRS工具,通过这个工具可以知道所有的灾害信息。除了使用WRS设备外,亚齐BMKG还使用短信、Whats App组、电报提供早期预警,亚齐BMKG脆弱区的人还安装了海啸警报器,作为大地震发生时的警报。同时,电台作为BMKG亚齐的媒体合作伙伴,也在提供早期预警方面发挥作用。所采用的策略是以新闻形式尽可能多地广播从亚齐BMKG获得的地震信息。除了预警信息外,广播媒体还更新了地震海啸灾害发生后的情况。社区对BMKG亚齐和媒体发布的早期预警的证词表明,BMKG传达的灾害信息帮助了易受灾地区的人们。然而,对于广播媒体来说,信息很少到达公众手中,因为目前公众对收听广播的兴趣很低,人们更喜欢利用互联网媒体获取灾害信息。

Existing eddy current non-destructive testing(NDT) techniques generally do not consider the inclination angle of inclined cracks, which potentially harms a larger region of a tested structure. This work proposes the use of 2 D scan images generated by using pulsed eddy current(PEC) non-destructive testing(NDT) technique in the quantification of the inclination and depth of inclined cracks. The image-based feature extraction technique e ectively identifies the crack axis, which consequently enables extraction of features from the extracted linear scans. The technique extracts linear scans from the images to allow the extraction of three novel image-based features, namely the length of extracted linear scans(LLS), the linear scan skewness(LSS), and the highest value on linear scan(LSmax). The correlation of the three features to surface crack inclination angles and depths were analysed and found to be highly dependent on the crack depths, while only LLS and LSS are correlated to the crack inclination angles.

本研究考察了2014年至2019年印尼总统大选期间的民粹主义现象。根据罗伯特.詹森的民粹主义理论,民粹主义被视为一种政治动员手段,换言之,是由动员和民粹主义言论组成的民粹动员。基于该定义,本文结合了文献回顾、历史分析及对印尼政治趋势的实际观察,将民粹动员归结为两种。一种是强硬伊斯兰组织基于保守伊斯兰所主张的民粹主义动员。这在一系列被称为Aksi BelaIslam（捍卫伊斯兰教行动）的示威游行中表现得淋漓尽致。另一种是Prabowo Subianto（普拉博沃·苏比安托）在2019年总统竞选时基于民族主义和亲贫情绪的民粹主义动员。二者分别基于宗教和经济层面,虽不尽相同却联系甚密。此外,本文还认为,若伊斯兰民粹动员对伊斯兰教在印尼政治中所扮演的角色仍坚持使用单一的保守解释,它可能会打破印度尼西亚共和国长期以来坚持的伊斯兰主义和民族主义之间的政治妥协。

In this paper we analyzed the bit error rate performance of a switching algorithm between spatial multiplex-ing and diversity for an OFDM MIMO system with ideal channel state information. The effect of channel estimation error was studied and we verified by simulations that the spatial multiplexing outperforms the switching algorithm. Given that the switching algorithm is based on the comparison of the channel matrix Demmel condition number to a threshold, its accuracy is compromised when channel estimation error in-creases. As a first intuitive solution, we proceeded to the adaptation of the threshold, but this didn’t lead to a pertinent improvement for the main reason that channel estimation errors did affect the MIMO techniques which use different constellation. Based on that, we proposed a new estimation technique that improved the bit error rate performance significantly.

Mannheimia haemolytica (M. haemolytica) is a gram negative bacterium which can infect humans and animals. It’s commensal as a normal flora of the nasopharynx and tonsils in cattle, sheep and goats, pneumonic pasteurellosis is one of the most economically important infectious disease in goats worldwide prevalence. This study aimed to investigate the incidence of M. haemolytica by bacteriological and molecular characterization in goats. One hundred nasopharyngeal swabs were collected from apparently healthy field goats, seven lung tissue specimens and five nasal mucus swabs from slaughtered goats in Baghdad. All samples were cultured on Blood and MacConky agars. Biochemical tests and EPI20E kit were used for identification of the suspected colonies. 5 (4.46%) isolates of M. haemolytica were identified phenotypicaly and confirmed diagnosis by polymerase chain reaction (PCR) technique using two primers 16s rRNA and 12s rRNA genes .The results of this study concluded that identification of M. haemolytica by PCR was in accordance with those of phenotypic tests and it providing the basis for effective preventative strategies through epidemiological studies performance.

在对柱坐标熔焊成形设备介绍的基础上,提出适用于回转框架结构的自适应分层、填充算法,通过三次择优筛选,减少网格的无效判断次数;建立了叠层堆积的误差模型,结合截面轮廓曲率变化动态计算适应成形精度要求的分层厚度;以NURBS作为基函数对分层轮廓进行最小二乘拟合,通过遗传算法寻找最佳拟合权值优化拟合结果.结果表明,成形过程中焊枪运行平稳,悬臂摆振较小;采用柱坐标特有的回转结构进行圆弧填充,避免了各焊缝间的成形时间等待和折线轮廓带来的过堆积现象,最后通过实际案例验证了分层软件的稳定性与可行性.

Introduction: Corticosteroid-induced lipomatosis are uncommon situation. We report a case of an extensive lipomatosis in a rheumatoid arthritis patient, who received a long term steroid therapy. Case report: A 49-year-old rheumatoid arthritis woman, who received for two years a mean dose of 15 mg/ day of prednisone equivalent, was admitted to the hospital for a six months history of progressive abdominal distension and dyspnea. Physical exam revealed typical symptoms of Cushing’s syndrome and an important increase of abdominal volume. Lipomatosis diagnosis with mesenteric, mediastinal, retroperitoneal and epidural localizations, was rapidly confirmed by sonography and computed tomography (CT) exams. Management was based on corticosteroid reduction as well as use of hygiene and dietary measures. Therapeutic efficacy was noted on a clinical basis within one year. Discussion: lipomatosis occurs as a less known complication of long-term steroid therapy. Its localizations are numerous. Epidural and mediastinal lipomatosis are more frequent than mesenteric or retroperitoneal ones. Most frequently asymptomatic, lipomatosis could sometimes be revealed by false symptoms. Medical treatment including corticosteroid with drawal or reduction and calorie restriction, can lead to clinical improvement. Surgery is reseved in advanced forms with serious complications.
