Environmental Impacts of Rice Cultivation  [PDF]
Mariane Silva de Miranda, Marina Leite Fonseca, Alexandre Lima, Tatiane Faustino de Moraes, Flávio Aparecido Rodrigues
American Journal of Plant Sciences (AJPS) , 2015, DOI: 10.4236/ajps.2015.612201
Abstract: This paper describes the major environmental aspects related to the cultivation of rice. Rice is one of the most important agricultural products and it is cultivated in almost all countries in the world. Its production requires usually large flooded areas. Under these conditions, many greenhouse gases are generated, such as carbon dioxide, methane, nitrogen oxides and its derivatives. Cultivation of rice is responsible by the release of relevant amounts of these gases and contributes decisively to global warming. In this sense, the major points described here are general environmental aspects, the mechanisms of production of greenhouse gases, bioremediation, mitigation using other techniques and possible improvements of the cultivation by fertilizers and chemicals.

Abstract: Objective: To apply an intensive and multidisciplinary education protocol in order to decrease, improve, delay or cancel the beginning of neuropathy and the manifestation of lesions in diabetic patients. Methodology: This is a cross-sectional descriptive study carried out at the Diabetes Mellitus Outpatient Clinic and Ward of Santa Marcelina Hospital in Porto Velho. This research was based on cases of patients with Diabetes and Diabetics with Leprosy. The criteria used to include the patients were: being treated with insulin therapy, not to be amputated, being on high medication of the leprosy at the moment of the evaluation and to present nutritional risk classification by the screening. The population was divided into two groups of fifteen patients: eight diabetic patients, four male and four female. Seven diabetics associated with leprosy were 4 males and 3 females. The monofilament test (Semmes-Weinstein 10 g) was used as the classification basis. Results and Discussion: Group A, called the intensive care group, began diabetes education work with medical, nutritional and rehabilitation guidelines by a multidisciplinary team for an average period of 15 days in the ward and after discharged with biweekly monitoring. Group B, called conventional care, received the same guidelines in outpatient care and the monitoring followed the quarterly protocol. Both groups were evaluated and reassessed for a period of 180 days in the outpatient clinic. Group A consisted of 8 (100%) patients, 4 (50%) diabetics and 4 (50%) diabetics and leprosy patients. Conclusion: Intensive education in diabetes showed an improvement in the sensitivity, healing and nutritional status of the patients, leading to an improvement in quality of life and disability level, reducing or delaying the beginning of neurological complications. The protocol intensive method demonstrated a 100% improvement in patients in group A.
Granulocyte-Colony Stimulating Factor Improves MDX Mouse Response to Peripheral Nerve Injury
Gustavo Ferreira Sim?es, Alexandre Leite Rodrigues de Oliveira
PLOS ONE , 2012, DOI: 10.1371/journal.pone.0042803
Abstract: Background G-CSF has been shown to increase neuronal survival, which may positively influence the spinal cord microenvironment during the course of muscular dystrophies. Methodology/Principal Findings Male MDX mice that were six weeks of age received a left sciatic nerve transection and were treated with intraperitoneal injections of 200 μg/kg/day of G-CSF 7 days before and 7 days after the transection. The axotomy was performed after the cycles of muscular degeneration/regeneration, consistent with previous descriptions of this model of muscular dystrophy. C57BL/10 mice were used as control subjects. Seven days after the surgery, the animals were sacrificed and their lumbar spinal cords were processed for immunohistochemistry (anti-MHC I, anti-Synaptophysin, anti-GFAP and anti-IBA-1) and transmission electron microscopy. MHC I expression increased in both strains of mice after the axotomy. Nevertheless, the MDX mice displayed a significantly smaller MHC I upregulation than the control mice. Regarding GFAP expression, the MDX mice showed a stronger astrogliosis compared with the C57BL/10 mice across all groups. Both groups that were treated with G-CSF demonstrated preservation of synaptophysin expression compared with the untreated and placebo groups. The quantitative analysis of the ultrastructural level showed a preservation of the synaptic covering for the both groups that were treated with G-CSF and the axotomized groups showed a smaller loss of synaptic contact in relation to the treated groups after the lesion. Conclusions/Significance The reduction of active inputs to the alpha-motoneurons and increased astrogliosis in the axotomized and control groups may be associated with the cycles of muscle degeneration/regeneration that occur postnatally. The G-CSF treated group showed a preservation of the spinal cord microenvironment after the lesion. Moreover, the increase of MHC I expression in the MDX mice that were treated with G-CSF may indicate that this drug performs an active role in regenerative potential after lesions.

BAR. Brazilian Administration Review , 2007, DOI: 10.1590/S1807-76922007000300002
Abstract: this paper examines the discourse configurations on the environmental theme in business organizations and its relevance to the understanding of the inclusion of ecological discourses in the discourses of organizational members. a case study into a brazilian telecommunications company offers empirical evidence. it begins with the understanding that organizations adopt several strategies in an attempt to disseminate a certain environmental discourse. as these efforts share space with other pressures, a fragmented discourse emerges. in this paper, the pressures of the environmental theme on organizations are discussed in order to understand this process. the second part of the argument focuses on the context of the case study - brazilian organizations - and, afterwards, the third part deals with ecological discourses in their insertions in organizational interests. the data of the case study were collected through documental research and 40 semi-structured interviews. the analysis was applied based on discourse analysis. in conclusion, an ambiguous discourse configuration was shown that offer elements for the understanding that philanthropy, legal obligation and organizational competitiveness need to be used together to offer legitimacy to the theme of environmental responsibility in business organizations
Environmental Discourses in Organizations: the Case of a Brazilian Mobile Telecommunications Company
Alexandre de Pádua Carrieri,Alfredo Rodrigues Leite da Silva
BAR. Brazilian Administration Review , 2007,
Abstract: This paper examines the discourse configurations on the environmental theme in business organizations and its relevance to the understanding of the inclusion of ecological discourses in the discourses of organizational members. A case study into a Brazilian telecommunications company offers empirical evidence. It begins with the understanding that organizations adopt several strategies in an attempt to disseminate a certain environmental discourse. As these efforts share space with other pressures, a fragmented discourse emerges. In this paper, the pressures of the environmental theme on organizations are discussed in order to understand this process. The second part of the argument focuses on the context of the case study – Brazilian organizations – and, afterwards, the third part deals with ecological discourses in their insertions in organizational interests. The data of the case study were collected through documental research and 40 semi-structured interviews. The analysis was applied based on Discourse Analysis. In conclusion, an ambiguous discourse configuration was shown that offer elements for the understanding that philanthropy, legal obligation and organizational competitiveness need to be used together to offer legitimacy to the theme of environmental responsibility in business organizations.

Abstract: the aim of this article is to understand the relationship between the meanings of social practices and strategy creation used by the produce merchants in vila rubim, vitória, es, from 1970 to the present time. to provide empirical evidence of the conceptual framework that was developed, we conducted a case study. the data gathered from the documents and interviews were treated using discourse analysis, and those obtained from observations were treated using content analysis. the possibility and the act of approaching the neighboring merchant's customer is the link that joins the homonymous strategy and tactic, but the process in each of them has different implications (strengthening or transgressing the established order) and develops in different and dynamic ways. thus, the denomination of strategies and practices is dynamic, relational and temporary because the focus is on the process that permeates each strategy and its articulations in the practices and meanings in each flow. in their socio-historic process, the produce merchants in the vr market articulate various flows. among them, the empirical investigation identified fourteen flows, nine as strategies and five as tactics, according to the social references assumed in the analysis.

Abstract: the goal of this paper is to present an analytical perspective of strategy as social practice in organizations by the articulation of proposals by foucault, certeau and moscovici on social dynamics. to accomplish its intents it discusses the convergences and divergences between social dynamics in foucault (1972, 1999, 2003a, 2003b), knowledge, power and subjectivities from moscovici (1961), and social representation theory (srt) as articulated with the concept of everyday strategies and tactics by certeau (1990). the paper presents the micro and macro delineations in investigations involving strategy-making practices in organizations over time. the studies of strategy as social practices are focused only on the micro-social level of ceo practices in organizations and don't consider the involvement of these practices at the macro-social level. thus, this paper aims at acknowledging the roles played by experimentation and by the researcher's theoretical position, but also at offering the actors an opportunity to present the micro and macro aspects that involve their strategy practices in a given organization. this way, a dynamic reference is obtained that allows for the comparison of empirical data in the analysis of strategy as a social practice.

Abstract: The aim of this article is to understand the relationship between the meanings of social practices and strategy creation used by the produce merchants in Vila Rubim, Vitória, ES, from 1970 to the present time. To provide empirical evidence of the conceptual framework that was developed, we conducted a case study. The data gathered from the documents and interviews were treated using discourse analysis, and those obtained from observations were treated using content analysis. The possibility and the act of approaching the neighboring merchant’s customer is the link that joins the homonymous strategy and tactic, but the process in each of them has different implications (strengthening or transgressing the established order) and develops in different and dynamic ways. Thus, the denomination of strategies and practices is dynamic, relational and temporary because the focus is on the process that permeates each strategy and its articulations in the practices and meanings in each flow. In their socio-historic process, the produce merchants in the VR Market articulate various flows. Among them, the empirical investigation identified fourteen flows, nine as strategies and five as tactics, according to the social references assumed in the analysis.

Diniz Pereira Leite Júnior, Ronaldo Sousa Pereira, Washington Santos de Almeida, Sara de Almeida Alves Sim?es, Ana Caroline Akeme Yamamoto, Janaina Vasconcellos Ribeiro de Souza, Evelin Rodrigues Martins, Fábio Alexandre Leal dos Santos, Rosane Christine Hahn
Advances in Microbiology (AiM) , 2018, DOI: 10.4236/aim.2018.84022
Abstract: Background: Indoor air quality in environments where there is great circulation of people, posing risks to the health of its occupants, including allergic problems, infections and contaminations, can be aided by climatic factors, chemicals and biological agents housed in these environments, influencing the location and providing favorable conditions for the degradation of bibliographic collections. The present study investigated the presence of fungi in indoor environments in seven public and private libraries in the central region of Brazil, Mato Grosso, and verified the impact on occupational health. Results: A total of 26,194 fungal specimens were isolated from 342 dust samples collected using three techniques: Andersen’s sampler (12.3%), exposure plate dish (25.1%) and sterile swab (62.6%). A total of 184 fungal species were identified: 156 (84.8%) mycelial fungi and 28 (15.2%) yeast fungi, belonging 54 fungal genera, 43 (79.6%) mycelial fungi and 11 (20.4%) yeast fungi. The genus Aspergillus (40.6%) was one of the main fungi present in indoor air. Aspergillus niger (12.3%) was identified as the most prevalent species in literary environments, followed by Cryptococcus spp. (7.1%) and Cladosporium cladosporioides (7.0%). In relation to seasonal distribution, there was a greater fungal isolation in the dry season (54%); followed by the rainy season (46%). Conclusion: These results suggest the substrates researched in the evaluated environments presented in the form of documents, books and papers associated with dust and air humidity become suitable for microbiological proliferation. These findings highlight the importance of minimizing the risk of exposure to fungal agents, identified in pathogenic and toxigenic microenvironments in library collections.
