The water is an universal soluble, fundamental to every living being. The main component to the human body and indispensable for any form of life, however, there is an increasing preocupation within the quality of their providers, which are the rivers, strands and springs, but as the time passes by are threatened by anthropogenic activities, main causer of the contamination and destruction of the local fauna and habitat. The principal objetictive of this research was to generate necessary information to further make use of this water, specifically located in Porto Velho, Rondônia, in Jamari’s River’s hidrographic basin sided with Green River’s, one affluent and one subfluent of Madeira’s River, which is one of the most important hidrographic basins of Amazon’s River, yet, lots of physical, chemicals and microbiological parameters were effected, like pH, turbidity, overall alkalinity, overall toughness, iron, chloride, color, fecal coliforms, that are capable of identify the contamination by anthropic action, obtaining the characteristics of the containing waters in the studied area, which in turn had favorable results, following the collected results we could confirm that all them were under acceptable and expectable parameters required by legislation in force of bathing, aquatic community preservation and human consumption, being the last one dependable of a simple threatment (chlorination).

The purpose of this research is to analyze the effect of housing generation on the performance of Soekarno-Hatta Street in Kasongan City. The independent variable that is used as a factor that influences the generation is the number of family members who work, the number of family members who attend school, the number of family members who do not work and do not attend school, the size of the household, the number of car ownership in the vehicle unit, the number of motorcycle ownership, the number of bicycle ownership, total ownership of vehicles in one house, total income per family per month, and type of house. The research sample was taken at Wengga Housing, Katingan Karya Citra Housing, and Griya Cipta Housing. Analysis is using multiple regression methods. From the results of the research, it was found that the trip generation produced by a housing (pcu / hour) was influenced by the average of total ownership of vehicles in one house and the number of houses occupied in one housing. The form of the generation equation is y = -165,791 + 41,850 x (average of total ownership of vehicles in one house) + 0,321 x (number of occupied houses). To maintain the performance of Jalan Soekarno-Hatta is still stable (LOSC) with the assumption that the external traffic flow growth is 3.5%, then in the fifth year housing development should not exceed 1.8 times (2350 units) or addition of houses can only be 1002 units.

For some cities like İstanbul, Rome, Paris and Cairo etc. as being the ones having natural and cultural heritage intensively, the most dominant planning data is the heritage itself. If we talk of sustainable planning, we should talk of not only the true planning regarding ecological principles, but also protection and reassesment of cultural and natural heritage at circumstances regarding sustainability, therefore this has to recognized as a true sign of ecological approach. On the other hand, one of the applied tools of Sustainability; “Sustainable Planning” as a correspondence of “Sustainable Development” in planning, is meant to use the nature and resources in the name of protecting them, for the sake of caring future generations. Today, World’s energy strategies based on solid fuel and petrol, unbalanced resource consumption with least sense, consuming environment negatively, increasing rates at population, consumption and urbanization, the lack of fast regeneration in nature, and many other parameters like the ones above which will remain unmentioned, threaten ‘Sustainability’ in direct. The purpose of this article, instead of consuming resources in the sense above, is to show of assessing cultural and natural heritages (for being ecological resource in essence and reflecting histo-cultural aggregation of humanity) and of using it as an input, by verifying the feasibility of it to be a paremeter providing-supporting the mentality of ecological planning and cultural sustainability. Sustainable planning must be expected to create principles and decisions regarding to protect-use balance for this heritage which is under the threat and pressure of civic developments. The use of cultural and historical heritage as an argument in Sustainable planning is given as of work and reports, international contracts and reported decisions related to these all are also given as references.

This study involved rural properties of the Brazilian Cerrado, which are necessarily consistent with the requirements of good agricultural practices for quality, innovation, and technology in the production and management of properties. Based on the knowledge and information as value-added production factors, we sought to highlight the opportunities for improving competitiveness, and thus a review of the literature on competitiveness, knowledge, and information as a differential factor for production with added value, innovation, and territorial technology as well as entrepreneurship. With the data from the field study, the objective was to show how knowledge and information, applied in production and social capital, can leverage competitiveness. The analyzes carried out using AHP indicate that some initiatives already aid in the promotion of innovation and technology applied to production, making it necessary, however, to encourage knowledge and information among producers and other stakeholders collectively, for the best costs and results. They also point to the low concern of producers with training and other productivity improvement techniques, such as selective harvesting. Authenticated that the producers opt for the sale of their production via commodity, aiming to profit quickly. Reasons for this are, in the non-perception of value added (sales in commodity); in the absence of rural structure for the processing and harvesting of the coffee required for special sale; in the precariousness of collective export agents (cooperatives are dependent on traders) and deficiencies in management for positioning in the properties (most work in scale).

One of the critical points in the framework of air transport, is the management of luggage at airports. Every year, a large number of people feel the need to travel for various reasons and that efficient management is a difficult task that needs to keep up with the growth demand in a satisfactorily. One of the problems that has not been solved is exactly the loss, misplacement or mishandling of baggage at airports, given the difficulty of the current management systems to monitor the baggage, which causes unwanted situations to life. Radiofrequency Identification Technology (RFID), integrated with an information system, presents itself as a solution to numerous daily setbacks in various segments, because its main feature is basically to capture information at a distance about some element in movement. By implementing a smart tag (tag) in each baggage, it becomes possible to trace it along the path. In order to solve this problem, the present work aims to develop a prototype software, integrated with RFID, to simulate the control of luggage at airports by means of three scenarios where luggage misplacement may occur.

The effect of properties like density, viscosity and flashpoint with alcohol additives in biodiesel blend fuel has been studied. Biodiesel blend fuel (B20) is used for characterization to compare with 5% and 10% of ethanol and methanol. The results indicated that flash point of B20 decrease drastically at 5% alcohols and increases at higher percentages. Increase in flash point as blend concentration increase may be considered better with respect to safety in fuel handling. In case of viscosity and density, cetane number and acid values decrease as the percentage of alcohol increases. Alcohols lower the flash point slightly and reduces the viscosity and density of blend fuel marginally, with this fuel ignition can start at lower temperature and able to burn completely. The combustion rate of fuel is increased due to more oxygen availability in alcohol that results in reducing the levels of pollutants in exhaust gases.

Global solar irradiance (Qg) is an important variable of the physical environment that has been constantly used in agrometeorological models, either for climatic characterization or to give support to radiometric studies developed for irrigation planning and crop weather modeling approaches. The current study aimed to compare measured daily values of Qg with estimates of this variable by means of four different methods. For that throughout the period comprised between March 28th of 2008 and August 8th of 2011 at Ponta Grossa, PR, Brazil, a simple linear regression study confronting radiometric data measured by a pyranometer and estimates of Qg was proposed herein. Global transmittance was conditioned by atmospheric cloudiness. The models based on mean global transmittance in daily basis performed more satisfactorily and generated values of Qg with accuracy and exactness at the site in study, as confirmed by the statistical parameters employed to validate the usage of models proposed by Angström-Prescott. However, the performance of the methodologies based on the determination of mean global transmittance under extreme atmospheric conditions, showed the highest Willmott coefficients, which was to be close to 1, reflecting then precision and reliability for the calculated values of Qg, when compared to observed values monitored at an automatic weather station.

The objective of this study was to generate a new methodology for the generation of vegetation index by drone cameras for the quantification of green cover area. For this study a drone of the DJI Mavic PRO quadricopter model was used. The flight plan was made using the Drone Deploy application and a total of 56 images were obtained, with a 60% side cover and 70% front cover. The images were processed in the professional Photoscan software version (1.4.2) resulting in mosaic area. The following ICVA equation was applied: ((pGreen-pRed / pGreen + pRed) * L) through the map algebra of ArcGis 10.3. The vegetation index was thus generated, without the need to use satellite images or multispectral data and thus generates a new way of identifying vegetation with the use of drones, Vants and RPAs, being a landmark in the advancement of studies of geotechnologies. The equation used will still be tested in new areas and different situations to show its capacity, and if necessary will be improved according to the observations made.

Quick Tool Exchange (QTE) acts to reduce losses and failures during the production process and throughput time, contributing to rapid response to market changes. The object of the work is a private school of the Municipality of Porto Velho, capital of Rondônia. The general objective is to study the building maintenance of a private school in the Municipality of Porto Velho / RO, focusing on QTE technology. Therefore, the specific objectives were to characterize the building maintenance in the study (1); compare the operational processes applied in the face of QTE concepts (2); and propose innovation for the operational improvement of building maintenance in operation (3). The building maintenance has a clear importance, since its compliance contributes to the preservation of life and health of users of any construction. Both the preventive and the corrective have been receiving the importance due to it, especially the preventive one, since this is always cheaper in comparison to the corrective one, since besides the damages caused to the physical structure of the building, there can exist to the users present in the occurrence of the fact. The methodological procedures consisted in carrying out a bibliographic survey followed by a case study. The results demonstrated measures approved and not approved by the QTE, suggesting simple innovations, but with significant consequences to the improvement of service rendering, minimizing costs in the area of building maintenance. This study is of interest to businessmen in general, especially the public or private educational sector, and those involved with the area of Production Administration.

This study aims to verify the use and mastery of linguistic knowledge in the writing process of Pedagogy students, in the form of Distance Education. The methodology was based on an exploratory analysis of texts produced in the face-to-face assessments that occurred in the first half of 2017. In the analysis of the answers, a descriptive graph of the errors and inadequacies observed was presented. The results show the commitment of writing to the meaning of the text, since this is a result of it. With this study, it was noticed that the university students have presented difficulties in expressing, in writing, their thoughts, their understandings and their opinions in an adequate and coherent way. Therefore, in order to minimize the anxiety experienced by these students at the time of writing, it is suggested that through the Instrumental Portuguese class, which part of the curriculum is, the linguistic aspects responsible for the production of meaning in texts and the interaction of the interlocutors. In order to meet the needs of undergraduate students, in the specific case of Pedagogy, since it concerns the training of teachers, professionals who will work in the literacy of children and young people and need to prioritize knowledge about language, reading and writing of these students.

We aimed to evaluate the incidence of weeds in the pre-planting of the summer crop as a function of planting system, herbicide use and irrigation management. The experiment was installed in field conditions, in RBD and 3 x 2 factorial scheme with eight replications. Treatments consisted in submitting rice to three management factors: water management – continuously flooded or intermittend irrigation (Factor A), coupled to the application (traditional control) or not (semi-ecological system) of herbicides (Factor B), and planting system – conventional soil tillage, minimum tillage and no till systems (Factor C). One year after rice cultivation, preceding the planting of the next cropping season, phytosociological evaluations of the weed communities were carried out. We assessed the overall infestation and weed species composition, which were classified by their respective density, frequency and dominance. We also estimated the diversity coefficients of Simpson and Shannon Weiner, and the sustainability coefficient of Shannon; treatments were also grouped by similarity in weed composition. In flood-irrigated rice, no till provides the lowest levels of weed infestation and, together with the conventional cropping system, results in values closer to the ecological sustainability; The application of herbicides in flooded rice crops reduces weed infestation, increases diversity and equalizes the ecological sustainability, compared to areas without the application of weed management methods. However, chemical control leads to the selection of resistant or tolerant species to herbicides, such as Polypogon sp.; Both continuous and intermittent water management systems did not cause changes in the level of infestation, composition or diversity coefficients.

This study investigates the effect of air pollution on rain water in Ado-Ekiti. Air pollution is becoming a global phenomenon and a source of concern to the entire world. Plants, animals, environment and public health are subjected to risks due largely to the earth that is getting warmer, ozone layer getting depleted, acid rain being recorded, all as a results of air pollution. This study was carried out in order to determine the pH level (i.e acidity and alkalinity), Total Dissolve Solids (TDS), Electrical Conductivity (E.C), Nitrate, E-Coli and Total Coliform count of the rainwater in Ado-Ekiti. The study area was classified into three environmental zones (high income, medium income and low income) based on standard of living of the residents. Fifty six samples of rainwater was collected in the three environmental zones between April and September, 2017 using small buckets that were washed and rinsed with distilled water. The collected samples were taken to the laboratory for chemical and bacteriological analysis. The results showed that the observation zone having pH in between 5.3 and 7.5 while EC fell in between 0 and 0.2 mS/cm indicating that the zones were polluted. Results of bacteriological analysis showed rainwater is free from bacteriological pollutants. It is concluded that gone are the days in the study area when rainwater can be collected for drinking purposes without treatment. Measures have to be taken in the area of efficient energy consumption and vehicular emissions control.

This interdisciplinary environment involves concepts from the area of communication, administration and information technology and seeks to meet the demands of generation, storage, retrieval, processing and transmission of information in this digital age. The AVNC involves three research fronts: rethinking the logic of news production, structuring a platform that is collaborative and defining what a business and management model should be that can give sustainability to this environment. In today's world, it is important to consider the reader's increasingly active participation in journalism, through information and communication technologies, thanks to the social changes that come with them. In times of cyberspace and cyberculture, it is necessary to rethink the dynamics of journalistic production. For this, authors like Pierre Lévy, Lúcia Santaella, Henry Jenkins, Caio Túlio Costa, among others were searched. In an era in which forms of collaborative ownership prevail, the platform being considered in this research follows the 3C collaboration model, according to Michalsky, Mamani, and Gerosa. A global platform where individuals interact, communicate, collaborate and gather information requires a business model and management that assists in managing the collaborative virtual news environment. For this, we used authors such as Alex Osterwalder, Eric Flamholtz, Siqueira and Crispim, Campos, among others. With this, an increasingly intelligent and collaborative environment is expected, with the active participation of all the agents involved. That is, what is proposed is the total interaction of the Internet user-reader.
