1可变信息板安全信息有效性研究(英文)显示文摘虽然多数先进技术应用的目的是改善路网的运行效率和安全性,但目前为止其在提高道路安全性方面的作用并不突出.例如,可以提供大容量、多方面信息的可变信息板,其设立之初的唯一目的是引导驾驶员的道路行驶.事实上,这种信息传达装置在不发布路段行驶信息的情况下,还可以发布交通安全信息以改善交通安全状况.本文选取两种禁止超速信息为研究对象,分析了该信息的发布对于驾驶员态度和路段行驶车速的影响.对近100名驾驶员进行抽样调查.测试路段为加拿大埃德蒙顿市和卡尔加里市间2号高速公路.研究结果表明,本文所选取的两种禁止超速标识对驾驶员态度和行驶车速产生的影响相对较小.TAY Richard DE BARROS Alex 2010交通运输系统工程与信息2010,10,3:6
2Chemical Exposure Hazardous for Fish Hyphessobrycon eques through the Incorrect Release of Oil in Amazon Region显示文摘Incorrect discard of oil used by fishing ship in the brazilian north region has become a common activity.Despite the possible hazard to the aquatic organisms,still missing scientific data about their toxicity.Thus,this study aimed to evaluate the stress and lethality caused by lubricant oil(FSAOLU)on fish Hyphessobrycon eques.Therefore,it was used six different concentration diluted in water(0,22,24,26,28,30 and 32%of oil)and three replaces during 96 hours.At the end or during the experiment(with dying fish),it was collected blood samples(cutting the caudal fin)to determine physiological changes.The FSAOLU showed mean lethal dose(LD50-96h)of 27.36%,classified as toxic causing alterations in glucose values from the 26%.The greater dilution of FSAOLU(32%)increased 115%in glucose values when compared to the control.Thus,lubricant oil when discarded in water,it present hazard to the aquatic organisms causing stress and mortality for fish being necessary adequate management to discard of this residue.Natalino da Costa Sousa Arthur dos Santos da Silva Keber Santos Costa Junior Francisco Alex Lima Barros Geisy Correa de Oliveira Pedro Rodrigo Nery de Souza Claudmilson Rodrigues de Mesquita Bruna de jesus Santos Alexander Damaceno Lima santos Winnícius Muniz dos Santos Sá Nayara Siqueira dos Santos Márcia Valéria Silva do Couto 2020Journal of Fisheries Science2020,2,2:0
3Enriched Artemia Nauplii with Commercial Probiotic in the Larviculture of Angelfish Pterophyllum scalare Lichtenstein (1823)显示文摘This study evaluated the effect of enriched artemia nauplii with commercial probiotic for angelfish larvae determining growth perfomance,survival and modulation of the intestinal microbiota.Therefore,it experiment occurred in completely randomized design with five treatments(T1-0.0,T2-1.5,T3-3.0,T4-4.5 and T5-6.0g of commercial probiotic)and four replaces during 20 days.After larvaculture,post larvae passed by biometric procedures to determine productive performance and then microbiological analysis.Occurred reduction of total heterotrophic bacteria while increased lactic acid bacteria in the intestinal tract from the post larvae for treatments T3,T4 and T5.The commercial probiotic also increased the survival and performance as final weight,weight gain and specific growth rate.For these reasons,the use of 3g of commercial probiotic promotes greater performance and intestinal modulation for angelfish larvae.Natalino da Costa Sousa José Araújo da Silva Emilly Monteiro Lopes Arthur Felipe Lima dos Santos Francisco Alex Lima Barros Carlos Alberto Martins Cordeiro Peterson Emmanuel Guimarães Paixão Estela dos Santos Medeiros João Carlos Nunes de Souza Márcia Valéria Silva do Couto 2020Journal of Fisheries Science2020,2,1:0
