Pesquisa sobre o semanário de esquerda Brasil de Fato, construído por um coletivo de dirigentes de movimentos sociais e representantes de organizações da sociedade civil, jornalistas, advogados e artistas, identificados politicamente e reunidos a partir de uma proposta apresentada pelo Movimento dos Trabalhadores Rurais Sem Terra. Lançado em janeiro de 2003, com a perspectiva de se tornar um meio de comunicação de massas, completou seis anos de existência resistindo às adversidades. O objetivo central é analisar o processo de construção e consolidação deste jornal popular-alternativo desde a formulação de seu projeto. São resgatados os caminhos percorridos para compreender não só as dificuldades inerentes à manutenção de um projeto com este perfil, mas também para analisar as contradições internas e externas que causaram as transformações em sua proposta original. A metodologia utilizada para este fim consistiu em pesquisa bibliográfica, entrevistas semi-estruturadas com lideranças e análise de conteúdo. Concluiu-se que, apesar de o jornal ter enfrentado uma série de condições adversas que justificam o não cumprimento de sua proposta original, o caráter de jornal de movimentos sociais já estava presente no Brasil de Fato desde a sua formação, principalmente no que tange as concepções do MST para o jornal.(AU)

This Doctoral Dissertation deals with the evaluation of impacts, through the Case Study on deviations or redirects present in contracts Pronaf B, at Governador Mangabeira - BA , from 2011 to 2013. From the questioning about the expected impacts not contribute to the effectiveness of the program ? It was possible the measurement of the hypothesis that the effectiveness of unexpected impacts stems from the logic of family farming, unique socio-economic conditions of individuals and family units. The methodology is structured in the theoretical framework regarding the impact assessment and family farming, data collection, questionnaires among redirected contracting credit in PRONAF B and interviews with institutional actors involved . The results confirmed the existence of a logic family farm, able to take own decisions their mode of reproduction of life. As for the impact assessment, we added the importance of the unexpected in the evaluation of public policy impacts , while study of effectiveness with the beneficiaries and the significant contribution of their views.

Brazil is the world's second largest producer of cassava, which most of the production is used to make flour and starch, generating large amounts of waste, cassava. In general, this waste is disposed of directly into the soil and waterways, causing serious environmental impacts. In view of this, the aim of this work was to evaluate the use of cassava wastewater water (cassava) as organic fertilizer in Brachiaria brizantha pasture. Marandu. The experiment was conducted at the Campus Macaíba the Federal University of Rio Grande do Norte. The treatments were increasing rates of cassava, applied to the soil as organic fertilizer. The experimental design was a randomized block design with six treatments and four replications. The treatments consist of cassava doses (0, 15, 30, 60 and 120 m³ ha- 1 ) and a treatment with mineral fertilizer (AM) in the form of NPK (140: 30: 120 kg ha-1 ). Three cuts with an interval of 60 days were carried out. The variables evaluated were: plant height; accumulation of morphological components of fodder; Trapping Light (IL); Leaf Area Index (LAI); Total chlorophyll (CT); Feature Production Seca (PMS). The dry matter production at a dose of 120 m³ha-1 had a quantitative increase, with a total production in 2796 kg ha-1 DM in the second cut, providing an increase of 493% compared to control, and the residual effect observed in the third cut caused a 100% increase compared to 0 m³ ha-1 . Comparing the PMS obtained with the use of AM and other treatments it was observed that it was the second cut equivalent to a dose of 120 m³ ha-1 and the third equivalence has been cut at doses 60 and 120 m³ha-1. For the variables plant height, IL, IAF, CT and leaves Mass adding cassava in the soil promoted a positive linear increase for the three cuts. However, with the AM the IAF was superior to the other treatments. The thatched mass reached its highest production (838 kg ha-1 DM) in the second cut when using a dose of 120 m³ha-1 . In dead material mass in the second and third sections, there was increased linearly increased total of 322 and 452% respectively, compared to a dose of 0 m³ha-1 . The use of cassava showed herbicidal effect for the variable mass of the undesirable negative linear response resulting in decreasing the amount of residue with increasing doses. Manipueira can be used as organic fertilizer in Brachiaria brizantha cv. Marandu for improvements in the productive characteristics, as promoted significant increases in 8 most of the variables studied, especially at a dose of 120 m³ha-1 . This benefits the environment by being alternative for disposal of cassava.

In this work, the treatment of wastewater from the textile industry, containing dyes as Yellow Novacron (YN), Red Remazol BR (RRB) and Blue Novacron CD (NB), and also, the treatment of wastewater from petrochemical industry (produced water) were investigated by anodic oxidation (OA) with platinum anodes supported on titanium (Ti/Pt) and boron-doped diamond (DDB). Definitely, one of the main parameters of this kind of treatment is the type of electrocatalytic material used, since the mechanisms and products of some anodic reactions depend on it. The OA of synthetic effluents containing with RRB, NB and YN were investigated in order to find the best conditions for the removal of color and organic content of the dye. According to the experimental results, the process of OA is suitable for decolorization of wastewaters containing these textile dyes due to electrocatalytic properties of DDB and Pt anodes. Removal of the organic load was more efficient at DDB, in all cases; where the dyes were degraded to aliphatic carboxylic acids at the end of the electrolysis. Energy requirements for the removal of color during OA of solutions of RRB, NB and YN depends mainly on the operating conditions, for example, RRB passes of 3.30 kWh m-3 at 20 mA cm-2 for 4.28 kWh m-3 at 60 mA cm-2 (pH = 1); 15.23 kWh m-3 at 20 mA cm-2 to 24.75 kWh m-3 at 60 mA cm-2 (pH 4.5); 10.80 kWh m-3 at 20 mA cm-2 to 31.5 kWh m-3 at 60 mA cm-2 (pH = 8) (estimated data for volume of treated effluent). On the other hand, in the study of OA of produced water effluent generated by petrochemical industry, galvanostatic electrolysis using DDB led to the complete removal of COD (98%), due to large amounts of hydroxyl radicals and peroxodisulphates generated from the oxidation of water and sulfates in solution, respectively. Thus, the rate of COD removal increases with increasing applied current density (15-60 mAcm-2 ). Moreover, at Pt electrode, approximately 50% removal of the organic load was achieved by applying from 15 to 30 mAcm-2 while 80% of COD removal was achieved for 60 mAcm-2 . Thus, the results obtained in the application of this technology were satisfactory depending on the electrocatalytic materials and operating conditions used for removal of organic load (petrochemical and textile effluents) as well as for the removal of color (in the case of textile effluents). Therefore, the applicability of electrochemical treatment can be considered as a new alternative like pretreatment or treatment of effluents derived from textiles and petrochemical industries.

The strong presence of the communication and information technologies (TICs) forced the productive routine of some media vehicles to go through significant changes. The same happened to the alternative agencies segment. Having a scarce literature and sources about this subject, this study’s objective is to understand how the Information Agency Frei Tito for Latin America (Adital) develops its proposal of alternative journalism, within the cyberspace, while aiming a Christian communication. For this finality, the study will describe and explain the practices of journalistic production, identifying the subjects involved and the relations maintained between them in this productive routine. Also, it will trace who and where these content replicators are and/or their online address. At first, it was presented a theoretical discussion about the concepts of “counter-hegemony”, alternative journalism and communicative citizenship, what brings us to the studies of Gramsci (2010), Peruzzo (2011), Moraes (2013), Paiva (2008), Coutinho (2008), Mata (2006), among other authors. Next, it will be approached briefly the historical path of the information agencies around the world and in Latin America, so that the study can focus on authors like Aguiar (2009), Pasti (2013) and Moraes (2010). This piece will draught a “methodologic route” for a qualitative approach with an exploratory and descriptive character. We gave up the etnometodological methods, what allow us to analyze the etnomethods or behavioral groups of action, procedures, activities and knowledge that constitutes these groups, giving them recognition and distinction. (COULON, 1995). To achieve the defined objectives, it was also used a bibliographical and documental research techniques, in addition to subject observation and semi-structured interviews. Finally, we analyze the collected data taking into consideration three pivots: the beginning of Adital; the practices, characteristics and subjects involved in the productive routine of the agency; and who are and where are these content replicators of content produced and transmitted by Adital. We can conclude that the production routine of an alternative agency and the counter-hegemonic of information is marked by some singularities regarding to the organization of the journalistic practice and to the obstacles found on the way. Our data allows us, even if there are still some doubts, to believe that Adital is a sort of independent information agency, alternative and counter-hegemonic, ergo, more close to a proposition of communicative citizenship.
