Abstract: A cultura do algod o tem grande importancia econ mica e social, visto que é a fibra mais utilizada no setor têxtil. Contudo, apresenta alta sensibilidade a plantas daninhas e há poucos herbicidas seletivos à cultura. Neste contexto objetivouse com este trabalho avaliar a seletividade de herbicidas aplicados em pré-emergência na cultura do algod o. Os herbicidas alachlor, S-metolachlor, diuron, prometryne, trifluralin e oxyfluorfen foram aplicados isoladamente e em misturas sobre a variedade FMT-701, nas localidades de Diamantino-MT e Campos de Júlio-MT. O delineamento experimental utilizado foiem blocos casualizados com 16 tratamentos e 4 repeti es. Para avaliar a seletividade foram realizadas avalia es de alturaaos 36, 66 e 150 dias após a aplica o (DAA), fitointoxica o aos 14, 21, 29 e 36 DAA, estande aos 21 e 49 DAA, número de ma s aos 141 DAA e produtividade do algod o em caro o aos 193 DAA. Os resultados indicaram que grande parte dos tratamentos causou injúrias na fase inicial da cultura e alguns tratamentos também proporcionaram menor altura de plantas em determinadas avalia es. Verificou-se ainda que os tratamentos n o proporcionaram diferen a significativa no estande de plantas, no número de ma s e nem na produtividade de algod o em caro o, evidenciando que todos os tratamentos avaliados podem ser utilizados no manejo de plantas daninhas.The culture of the cotton has great economic and social importance, because it is the fiber more frequently used in the textile section. However, the crop has high sensibility to weed and there are few selective herbicides for this crop. In this context, the objective of this study was to evaluate the selectivity of applied herbicides in pre-emergency on the culture of the cotton. The herbicides alachlor, S-metolachlor, diuron, prometryne, trifluralin and oxyfluorfen were separately applied and in mixtures with the variety FMT-701, in the places of Diamantino-MT and Campos de Júlio-MT. The experimental delimitation used was randomized blocks with 16 treatments and 4 repetitions. To evaluate the selectivity of the evaluations the height of the plants were observed 36, 66 and 150 days after the application (DAA), phytotoxicity to 14, 21, 29 and 36 DAA, stand to 21and 49 DAA, number of apples to 141 DAA and productivity of the cotton in pit to 193 DAA. The results indicate that great part of the treatments provided damage during the initial phase of development and some treatments also resulted in the reduced height of plants at certain periods of evaluation. It was verified that the treatments did not prov
Construindo um programa de educa??o com agentes comunitários de saúde

Abstract: aiming at contributing inputs to the learning process of health community agents from health family strategy, this study has sought to devise an educational program for qualifying seven community agents from the family health unit in a neighborhood in the brazilian city of sorocaba. speeches on the perception these agents have of their work, their difficulties and proposals were captured and analyzed within the framework of the "collective subject speech". results showed the group's learning needs, and guided the devising and implementation of the educational program, which adopted the emancipatory education model. this knowledge was built by the agents through a problem-focused reality, debating, searching for solutions, and implementing intervention projects. they noticed that being a community health agent means, above all, to struggle and harness community forces for purposes of defending health & education public services and for improving social health determinants.
Between the Barrio and the City: Pathways of Work among Scavenging Families  [PDF]

Open Journal of Social Sciences (JSS) , 2014, DOI: 10.4236/jss.2014.24024
Abstract: In this article, I will reconstruct, through brief stories, some of the traits that characterize the way of life of families in the El Salvador neighborhood, in Buenos Aires, Argentina, go scavenging everyday in Buenos Aires city. These stories will not only tell us who they are and how they arrived at the El Salvador neighborhood, from where, and in what manner they began to salir con la carreta, but will also permit us to move closer to the day-to-day existence of these families in relationship to their life in the barrio and the activities they engage in, thereby giving us a fuller understanding of family dynamics. In the research that originated this paper, I followed an ethnographical perspective to study and analyze the way of life of those families living from the recyclable waste they recollect in Buenos Aires city.
A Lorentz invariant velocity distribution for a relativistic gas
Evaldo M. F. Curado,Ivano D. Soares
Physics , 2014,
Abstract: We derive a Lorentz invariant distribution of velocities for a relativistic gas. Our derivation is based on three pillars: the special theory of relativity, the central limit theorem and the Lobachevskyian structure of the velocity space of the theory. The rapidity variable plays a crucial role in our results. For $v^2/c^2 \ll 1$ and $1/\beta=kT/2 m_0 c^2 \ll 1$ the distribution tends to the Maxwell-Boltzmann distribution. The mean $\langle v^2 \rangle$ evaluated with the Lorentz invariant distribution is always smaller than the Maxwell-Boltzmann mean and is bounded by $\langle v^2 \rangle/c^2=1$. This implies that for a given $\langle v^2 \rangle$ the temperature is larger than the temperature estimated using the Maxwell-Boltzmann distribution. For temperatures of the order of $T \sim {10^{12}}~ K$ and $T \sim {10^{8}}~ K$ the difference is of the order of $10 \%$, respectively for particles with the hydrogen and the electron rest masses.

Tajer,Débora;
Anuario de investigaciones , 2006,
Abstract: this work aims to identify how gender subjetivation process in women with coronary heart disease, can collaborate in understanding women's particular risk in this disease. has a critical point of view related to the explanation of young women less incidence linked to biological factors, expanding the framework to a more comprenhensive point of view. by the same token, this framework considers the health-disease-care process of a person produced by biological, phychological and social determinants. the specific collaboration of this work consists in focusing on the psychosocial approach to the conformation of women gender subjetivation in orden to understand this part of women's own way of getting in risk. taking in account that former studies had understood it as a "masculinization" process of the affected population or an increased of biological risk factors in the cause, more than and increase of women's particular psychosocial risk factors.
Inmigración y discriminación en la frontera argentino-paraguaya
Betrisey Nadali, Débora;
Migraciones internacionales , 2007,
Abstract: within the framework of argentinean society, in recent decades, obvious processes of stigmatization have been established that give rise to the production of "others" on the basis of their condition of "border immigrants" (such as paraguayans, chileans and bolivians), who are always prey manipulation. in this essay, i propose to delve into the logic of certain premises and interpretative frameworks drawn from sociology and anthropology, in order to analyze these processes of stigmatization. these theoretical-methodological perspectives enable one to record the personal experience of immigrants, and focus on the "language of resistance" through which these groups dismantle and re-create their stigmatized identities. these reflections are the result of ethnographic material collected between 1999 and 2000 in the city of posadas (misiones, argentina) adjoining the city of encarnación (district of itapúa, paraguay).

Cadernos de Pesquisa , 2008, DOI: 10.1590/S0100-15742008000300008
Abstract: the purpose of this study is to discuss the contribution of recent studies for understanding the conditions that make extended learning paths possible in low-income segments. the meticulous analysis of its results and an interview with a student of a highly selective higher education course from this background enables us to raise some issues. the review of some studies on the subject evidencing the central role of the family in extended learning paths also enables us to question some of the meanings commonly assigned to extended learning in low-income segments, such as conformism, suffering, and cultural disruption. the need for further investigation on the role of school, as well as on the existence of other meanings related to school access and the experience of poor students in higher education courses has been made evident.
