1多媒体学习研究的演进显示文摘在起源于教育领域之外的多媒体学习资源(像光盘和网络)大规模涌入之前,关于多媒体对学习的影响方面的实验研究已经有几十年的时间。尽管研究的结果并不是决定性的,但是前两代多媒体研究帮助我们确定了影响有效多媒体设计的要素。本文总结了现有研究的结论,评述了每一代多媒体研究的主要理论问题、研究方向以及不足之处。论文还讨论了已经开始受到人们关注的第三代多媒体设计和学习研究新动向,也提出了若干表来发展趋势的建议。Haido Samaras 张丽 盛群力 2006远程教育杂志2006,24,6:16
2Influence of fly ash and sewage sludge application on wheat biomass production,nutrients availability,and soil properties显示文摘The influence of fly ash(FA)applied alone and/or with sewage sludge(SS)on wheat(Triticum vulgare)grain yield,biomass production and soil properties was studied in a field experiment.The results showed that both FA and SS significantly increased grain yield and plant biomass.FA applied alone increased significantly soil pH and EC while FA applied together with SS did not significantly affect them compared to mono FA treatment.Soil pH and EC values increased with time in FA and FA-SS treatments.SS increased soil organic matter and total N content and SS applied together with FA increased also available soil B.From the plant nutrients tested only tissue N concentration was increased significantly in all treatments compared to control.Copper,Zn,Mn,Ni,and Pb at both available and total concentrations are significantly affected.Christos Tsadilas Vasilios Samaras E.Evangelou Sabry M.Shaheen 2014International Journal of Coal Science & Technology2014,1,2:8

5Review of state-of-the-art decision support systems (DSSs) for prevention and suppression of forest fires显示文摘Forest ecosystems are our priceless natural resource and are a key component of the global carbon budget. Forest fires can be a hazard to the viability and sustainable management of forests with consequences for natural and cultural environments, economies, and the life quality of local and regional populations. Thus, the selection of strategies to manage forest fires, while considering both functional and economic efficiency, is of primary importance. The use of decision support systems(DSSs) by managers of forest fires has rapidly increased. This has strengthened capacity to prevent and suppress forest fires while protecting human lives and property. DSSs are a tool that can benefit incident management and decision making and policy, especially for emergencies such as natural disasters. In this study we reviewed state-of-the-art DSSs that use: database management systems and mathematical/economic algorithms for spatial optimization of firefighting forces; forest fire simulators and satellite technology for immediate detection and prediction of evolution of forest fires; GIS platforms that incorporate several tools to manipulate, process and analyze geographic data and develop strategic and operational plans.Stavros Sakellariou Stergios Tampekis Fani Samara Athanassios Sfougaris Olga Christopoulou 2017Journal of Forestry Research2017,28,6:3
6Individualization of chronic hepatitis C treatment according to the host characteristics显示文摘Hepatitis C virus(HCV)infection is a global health problem that affects more than 170 million people worldwide.It is a major cause of cirrhosis and hepatocellular carcinoma,making the virus the most common cause of liver failure and transplantation.The standardof-care treatment for chronic hepatitis C(CHC)has been changed during the last decade and direct acting antiviral drugs have already been used.Besides,understanding of the pathogenesis of CHC has evolved rapidly during the last years and now several host factors are known to affect the natural history and response to treatment.Recent genome-wide association studies have shown the important role of interleukin-28B and inosine triphosphatase in HCV infection.The present review article attempts to summarize the current knowledge on the role of host factors towards individualization of HCV treatment.Nikolaos K Gatselis Kalliopi Zachou Asterios Saitis Maria Samara George N Dalekos 2014World Journal of Gastroenterology2014,20,11:2
7Stable gastric pentadecapeptide BPC 157 in the treatment of colitis and ischemia and reperfusion in rats: New insights显示文摘AIM To provide new insights in treatment of colitis and ischemia and reperfusion in rats using stable gastric pentadecapeptide BPC 157. METHODS Medication [BPC 157,L-NAME,L-arginine(alone/combined),saline] was bath at the blood deprived colon segment. During reperfusion,medication was BPC 157 or saline. We recorded(USB microscope camera) vessel presentation through next 15 min of ischemic colitis(ICrats) or reperfusion(removed ligations)(IC + RL-rats);oxidative stress as MDA(increased(IC-and IC + RLrats)) and NO levels(decreased(IC-rats);increased(IC + RL-rats)) in colon tissue. IC + OB-rats [IC-rats had additional colon obstruction(OB)] for 3 d(IC + OBrats),then received BPC 157 bath. RESULTS Commonly,in colon segment(25 mm,2 ligations on left colic artery and vein,3 arcade vessels within ligated segment),in IC-,IC + RL-,IC + OB-rats,BPC 157(10 μg/kg) bath(1 m L/rat) increased vessel presentation,inside/outside arcade interconnections quickly reappeared,mucosal folds were preserved and the pale areas were small and markedly reduced. BPC 157 counteracted worsening effects induced by L-NAME(5 mg) and L-arginine(100 mg). MDA-and NO-levels were normal in BPC 157 treated IC-rats and IC + RLrats. In addition,on day 10,BPC 157-treated IC + OBrats presented almost completely spared mucosa with very small pale areas and no gross mucosal defects;the treated colon segment was of normal diameter,and only small adhesions were present.CONCLUSION BPC 157 is a fundamental treatment that quickly restores blood supply to the ischemically injured area and rapidly activates collaterals. This effect involves the NO system.Antonija Duzel Josipa Vlainic Marko Antunovic Dominik Malekinusic Borna Vrdoljak Mariam Samara Slaven Gojkovic Ivan Krezic Tinka Vidovic Zdenko Bilic Mario Knezevic Marko Sever Nermin Lojo Antonio Kokot Marijan Kolovrat Domagoj Drmic Jaksa Vukojevic Tamara Kralj Katarina Kasnik Marko Siroglavic Sven Seiwerth Predrag Sikiric 2017World Journal of Gastroenterology2017,23,48:2

10Grain-size end-members and environmentally sensitive grain-size components: A comparative study in the mud shelf depocenters off southern Brazil显示文摘The current study aims to do a comparative analysis of the results obtained with two End-Member(EM)grain-size modeling techniques(AnalySize and BasEMMA)and the Environmental Sensitive Grain-Size(ESGS)modeling for sediment samples collected in the mudbelts of the southern Brazilian shelf.The methods were compared using grain-size data from the south Brazilian shelf,and the results are discussed here.It is the first time that the concept of ESGS,in its present form,is utilized outside China.The results show that despite its relative ease of use,the ESGS is not fully comparable to the EM analyses,and only two grain-size ESGS classes were recognized as analogous to EMs.The comparison of the AnalySize and BasEMMA procedures also revealed significant differences between the techniques.A comparative analysis between the two EM techniques revealed advantages in the BasEMMA,especially in the better correlation of the end-members with the original grain size distribution.The analysis of the geographical distribution of the EM abundances allowed point sources of sandy populations to be recognized as well as the contribution of the Rio de la Plata as a source of silty sediments to be inferred.Michel Michaelovitch de Mahiques Samara Cazzoli y Goya Maria Carolina da Silva Nogueira de Matos Rodrigo Augusto Udenal de Oliveira Bianca Sung Mi Kim Paulo Alves de Lima Ferreira Rubens Cesar Lopes Figueira Marcia Caruso Bícego 2021International Journal of Sediment Research2021,36,2:2
