Plagiarism is the act of presenting as an idea or work of another author without mentioning it as a source. This practice has been common in academia, especially with the ease offered by the use of the internet. This study aims to verify how students of the Information Systems course understand plagiarism and what possible actions to reduce this practice in academic work. The research was carried out through semi-structured questionnaires, using research and descriptive analysis. The results showed that students do not have full knowledge of plagiarism, not being able to identify specific types of plagiarism, the correct use of citations and the need to place direct and indirect citations of the sources used in their texts.
抄袭是指在没有提及出处的情况下,以其他作者的想法或作品的形式呈现的行为。这种做法在学术界很常见,尤其是由于互联网的使用提供了便利。本研究旨在验证信息系统课程的学生如何理解剽窃,以及在学术工作中采取哪些可能的行动来减少这种做法。本研究采用半结构化问卷调查的方式,采用研究与描述性分析相结合的方法。结果表明,学生对抄袭没有充分的了解,不能识别具体的抄袭类型,不能正确使用引文,不能在文本中直接和间接地引用出处。

Socioeconomic factors can influence the quantitative aspects of services that are inherent to basic sanitation components. This study consists of the application of the Pearson correlation between drinking water consumption and socioeconomic parameters in order to measure and classify the influence of the municipal human development index and the per capita gross domestic product on per capita water consumption. Correlations were analyzed using data from 417 municipalities in the state of Bahia, Brazil from 2002 to 2016. The results demonstrate the occurrence of a weakly positive Pearson linear correlation between the human development index and water consumption and a weakly negative correlation between the gross domestic product and the per capita water consumption for most of the analyzed municipalities. The operational characteristics of the tools usedhere proved to be efficient, simple, and important for building studies aimed toward the planning and improvement of water supply systems.
社会经济因素可以影响基本卫生组成部分所固有的服务的数量方面。本研究应用饮用水消费量与社会经济参数之间的Pearson相关性,以衡量和分类城市人类发展指数和人均国内生产总值对人均用水量的影响。利用2002年至2016年巴西巴伊亚州417个城市的数据分析了相关性。结果表明,在大多数被分析的城市中,人类发展指数与用水量之间存在弱正的Pearson线性相关,而国内生产总值与人均用水量之间存在弱负相关。这里使用的工具的操作特点被证明是有效的、简单的,对于旨在规划和改进供水系统的建筑研究是重要的。

This study aimed to analyze the feasibility of building a landfill in the municipality of Rancharia-SP, aiming to meet the standards established by the National Solid Waste Policy (PNRS), reduce costs with the proper disposal of waste, reduce environmental pollution and avoid possible penalties imposed by the Environmental Company of the State of São Paulo (CETESB). A quantitative approach was carried out to verify the economic viability of investment alternatives, with the application of Economic Engineering methods, such as the Net Present Value (NPV) method. The information needed for the analysis, regarding the projections of solid waste generation by the municipality of Rancharia, the costs of outsourcing the proper disposal of waste, the costs of the life cycle stages of a landfill, were raised through research bibliographic and documentary. Thus,and considering that, so far, the municipality pays for the transshipment and the proper disposal of its waste at the landfill of a neighboring municipality (23km), it was concluded that the construction of a landfill in Rancharia -SP is the alternative more economically profitable, being able to present better returns with the realization of financing, whose rates are lower than the opportunity cost, as well as with the implementation of more efficient systems of selective collection of recyclable materials.
本研究旨在分析在Rancharia-SP市建设垃圾填埋场的可行性,旨在满足国家固体废物政策(PNRS)制定的标准,通过适当处理废物降低成本,减少环境污染,避免圣保罗州环境公司(CETESB)可能施加的处罚。运用经济工程方法,如净现值法(NPV),采用定量方法验证投资选择的经济可行性。分析所需要的资料,包括兰查里亚市对固体废物产生的预测、外包适当处理废物的费用、填埋场生命周期阶段的费用,都是通过研究书目和文献资料提出的。因此,考虑到到目前为止,市政当局支付转运和在邻近市政当局(23公里)的垃圾填埋场妥善处理其废物的费用,得出的结论是,在Rancharia -SP建造垃圾填埋场是一种更具经济效益的替代方案,能够通过实现融资提供更好的回报,其利率低于机会成本。以及实施更有效的选择性收集可回收材料的系统。

The São Jorge stream micro basin, located in the municipality of Tarabai-SP, is divided into rural and urban areas, with the presence of livestock activities, residential and commercial buildings, as well as a flour industry. Human interference has been modifying water resources, making it necessary to monitor them and identify negative changes. Thus, in order to analyze the water quality of this micro-basin, pH, chemical oxygen demand, turbidity, electrical conductivity and nitrogen were analyzed to check for possible disagreements with the legislation. The results were compared to CONAMA 357/2000, which allowed to find discrepancies in the sample with greater proximity to the industry (4). The qualitative analysis of the stream made it possible to understand how much interference in the micro basininterferes negatively in thequality of its water; they are often not visible or easy to identify, but they are present altering the characteristics of the water.
s o Jorge溪流微盆地位于塔拉贝- sp市,分为农村和城市地区,有畜牧活动、住宅和商业建筑,以及面粉工业。人类的干预一直在改变水资源,因此有必要对其进行监测并查明负面变化。因此,为了分析该微流域的水质,我们分析了pH值、化学需氧量、浊度、电导率和氮含量,以检查是否与立法存在分歧。将结果与CONAMA 357/2000进行比较,可以发现与工业更接近的样品中的差异(4)。对溪流的定性分析使人们有可能了解微盆地中有多少干扰对其水质产生负面影响;它们通常不可见或不易识别,但它们的存在改变了水的特性。

Tension and compression stresses are introduced in the concrete when Portland Cement are used in large volumes, inducing pathologies such as micro-cracks related to sudden changes in temperature. Sucrose is used as a cement hydration retarding additive and produce good results. In this sense, vinasse is a source of sucrose still little explored. Vinasse is a by-product of the sugar and alcohol industry, produced in large volumes, making it very attractive in this application. This study investigates the influence of vinasse on hydration in cement pastes. The total reducing sugars (TRS) and total soluble sugars (AST) as well as the sucrose present in vinasse was determined through Fehling method. The amount of 25%, 50% and 100% of vinasse were used to substitute water in cement pastes composition. The consistency, initial and final setting time and thermal variation during hydration of pastes were. The results show that the lower amount of substitution (25%) leads to an increase in the initial and final setting time, while larger amounts did not cause the same benefits. The calorimetry test confirmed the results obtained by the setting time test, showing less heat of hydration of the paste with 25% substitution of water for vinasse.
当大量使用波特兰水泥时,混凝土中会引入拉应力和压应力,从而引起与温度突然变化相关的微裂缝等病症。将蔗糖作为水泥水化缓凝剂,取得了良好的效果。从这个意义上说,酒糟是蔗糖的一种来源,目前还很少被探索。酒糟是制糖和酒精工业的副产品,产量很大,因此在这方面的应用非常有吸引力。研究了酒糟对水泥浆体水化性能的影响。采用Fehling法测定了酒液中总还原糖(TRS)、总可溶性糖(AST)及蔗糖的含量。采用25%、50%和100%的酒糟量替代水泥浆组成。研究了膏体的稠度、初凝时间和终凝时间以及水化过程中的热变化。结果表明:较低的替代量(25%)会导致初始和最终凝固时间的增加,而较大的替代量则不会产生相同的效果。量热试验证实了凝结时间试验的结果,表明用25%的水代替酒渣,膏体的水化热减少。

In Brazil, bananas are extremely important because they are the second most cultivated fruit after citrus. Therefore, this work aimed to perform the osmotic dehydration of the dwarf banana (Musa acuminata'Dwarf Cavendish')associated with microwave drying. The characterization of the raw material, dehydration and domestic microwave drying, drying kinetics, rehydration capacity and characterization of the final product were performed. As a result it was noted that microwave drying was satisfactory for drying. A moisture content of 29.38% was obtained, a pH of 4.77 and a rehydration capacity of 174% in banana without pretreatment and 32.33%, 4.83% and 120% respectively for osmotically dehydrated. The use of this combination proved to be a viable alternative in extending the life of the Dwarf Cavendish.

In the refrigeration industry, a large amount of water is used throughout processes, generating effluents that need treatment before release. The purpose of this work was to make a comparative study of three coagulants used in the treatment of effluents: Aluminum Polychloride (PAC), Aluminum Sulphate (Al2(SO4)3) and Vegetable Tannin, with the aid of a flocculant (Anionic Polymer) by analyzing COD removal efficiency and turbidity. Jar coagulation / flocculation tests were conducted to optimize the concentration of coagulants. It was found that the natural coagulant presented a small variation in the pH parameter, avoiding the use of chemicals for its correction. The results of turbidity removal percentages indicated a great potential for Tannin when compared to the other chemical coagulants.
在制冷工业中,整个过程都要使用大量的水,产生的废水在排放前需要处理。本研究对聚氯化铝(PAC)、硫酸铝(Al2(SO4)3)和植物单宁三种混凝剂在絮凝剂(阴离子聚合物)的辅助下处理废水进行了对比研究,分析了COD的去除率和浊度。通过缸内混凝/絮凝试验优化混凝剂的浓度。结果表明,天然混凝剂的pH参数变化较小,避免了使用化学药剂进行校正。浊度去除率的结果表明,与其他化学混凝剂相比,单宁具有很大的潜力。

The study of hydrological phenomena is an important source of information about the water behavior, providing valuable subsidies for water resources management at local, regional and global scales. In the present work, was performed a critical-constructive analysis of the products generated by digital satellite image processing of the Basin Hydrographic of Pardo, in the region of the Water Resources Management Unit-04 of the State of São Paulo. The analysis of the elaborated thematic maps demonstrated as main attribute of the delimited area for study the fact that most of its territory is composed of flat or gently undulating relief areas, as well as sub-basins that present high slopes, a combination responsible for directly influencing the accumulation of the flow of its water resources, which significantly
对水文现象的研究是了解水行为的重要信息来源,为地方、区域和全球尺度的水资源管理提供了宝贵的补贴。在目前的工作中,在圣保罗州水资源管理单位-04地区,对Pardo流域水文的数字卫星图像处理产生的产品进行了关键的建设性分析。对精心制作的专题地图的分析表明,作为研究划界地区的主要属性,其大部分领土由平坦或平缓起伏的地形以及呈现高边坡的子盆地组成,这一组合直接影响了其水资源流量的积累,这一影响显著
