Self-dual Maxwell Chern-Simons Solitons In 1+1 Dimensions

We study the domain wall soliton solutions in the relativistic self-dual Maxwell Chern-Simons model in 1+1 dimensions obtained by the dimensional reduction of the 2+1 model. Both topological and nontopological self-dual solutions are found in this case. A la BPS dyons here the Bogomol'ny bound on the energy is expressed in terms of two conserved quantities. We discuss the underlying supersymmetry. Nonrelativistic limit of this model is also considered and static, nonrelativistic self-dual soliton solutions are obtained.Comment: 18 pages RevTex, 2 figures included, to appear in Phys. Rev.

The BPS Domain Wall Solutions in Self-Dual Chern-Simons-Higgs Systems

We study domain wall solitons in the relativistic self-dual Chern-Simons Higgs systems by the dimensional reduction method to two dimensional spacetime. The Bogomolny bound on the energy is given by two conserved quantities in a similar way that the energy bound for BPS dyons is set in some Yang-Mills-Higgs systems in four dimensions. We find the explicit soliton configurations which saturate the energy bound and their nonrelativistic counter parts. We also discuss the underlying N=2 supersymmetry.Comment: 16 pages, LaTeX, no figure, a minor change in acknowledgment

Gray matter density reduction associated with adjuvant chemotherapy in older women with breast cancer

PURPOSE: The purpose of this study was to evaluate longitudinal changes in brain gray matter density (GMD) before and after adjuvant chemotherapy in older women with breast cancer. METHODS: We recruited 16 women aged ≥ 60 years with stage I-III breast cancers receiving adjuvant chemotherapy (CT) and 15 age- and sex-matched healthy controls (HC). The CT group underwent brain MRI and the NIH Toolbox for Cognition testing prior to adjuvant chemotherapy (time point 1, TP1) and within 1 month after chemotherapy (time point 2, TP2). The HC group underwent the same assessments at matched intervals. GMD was evaluated with the voxel-based morphometry. RESULTS: The mean age was 67 years in the CT group and 68.5 years in the HC group. There was significant GMD reduction within the chemotherapy group from TP1 to TP2. Compared to the HC group, the CT group displayed statistically significantly greater GMD reductions from TP1 to TP2 in the brain regions involving the left anterior cingulate gyrus, right insula, and left middle temporal gyrus (pFWE(family-wise error)-corrected < 0.05). The baseline GMD in left insula was positively correlated with the baseline list-sorting working memory score in the HC group (pFWE-corrected < 0.05). No correlation was observed for the changes in GMD with the changes in cognitive testing scores from TP1 to TP2 (pFWE-corrected < 0.05). CONCLUSIONS: Our findings indicate that GMD reductions were associated with adjuvant chemotherapy in older women with breast cancer. Future studies are needed to understand the clinical significance of the neuroimaging findings. This study is registered on ClinicalTrials.gov (NCT01992432)

CONSUMO SUSTENTÁVEL E PRESERVAÇÃO DO AMBIENTE

Este trabalho tem como tema consumo sustentável e preservação do ambiente e como problemática envolver alunos, pais, professores e comunidade escolar em defesa da sustentabilidade do Meio Ambiente que os cerca. Tendo como objetivo compreender o sentido de ser um sujeito consciente e participativo nas ações de preservação do Meio Ambiente. Como metodologia, optamos por trabalhar com a pesquisa participante, partindo do princípio de que todos e todas têm a aprender e a ensinar, onde todos juntos se divertem enquanto levantam os problemas da comunidade, sonham e encontram soluções para os mesmos, reconhecem os desafios e/ou dificuldades do caminho, porém planejam ações efetivas entusiasticamente. Definitivamente, foi-se o tempo em que consumir era algo despretensioso e que os desejos, por mais supérfluos que fossem, deveriam ser atendidos a qualquer preço. Hoje, a humanidade sente na pele as consequências de centenas de anos de consumo desenfreado e irresponsável, na forma do aquecimento global, poluição das águas, extinção de animais, volume excessivo de material para descarte (lixo seco), lixões a céu aberto e outros desastres ecológicos. Para abrandar esses impactos negativos, faz-se necessário não só uma mudança de atitude, mas principalmente formar consciência da responsabilidade de cada um no coletivo. A ideia básica do consumo consciente é transformar o ato de consumo em uma prática permanente de cidadania. Por isso, é fundamental estar bem informado sobre os produtos e serviços que serão adquiridos ou contratados. O poder de transformação social está nas mãos de nós consumidores, e cabe a cada um de nós escolhermos com consciência os produtos, e conhecermos os fornecedores, empresas que têm responsabilidade e compromisso ético, que respeitam os direitos humanos e os limites naturais do planeta. E, é esse comportamento, que esperamos desenvolver em nossos jovens e na comunidade em geral. A escola fez o trabalho voltado ao tema do projeto, durante o primeiro semestre deste ano e, pode-se perceber algumas mudanças na atitude do grupo de educandos como a valorização e o cuidado com cada espaço da escola, a preocupação em descartar os resíduos na lata correspondente a sua cor, o reaproveitamento de embalagens, principalmente as de vidro. Além disso, as atividades desenvolvidas na escola aproximaram a comunidade em geral, esta passou a estar presente, apoiar e incentivar os eventos organizados pela escola. É possível perceber a satisfação das famílias, ao verem seus filhos participando das atividades organizadas pela escola e também, um maior interesse em participar de atividades práticas propostas envolvendo concepções e ações de cidadania

Contando história: memória de velhos e o resgate oral da educação de imigrantes pomeranos

O presente artigo tem por objetivo registrar e, desta forma, resgatar fragmentos da história da educação do campo, dos imigrantes pomeranos, nos municípios de Canguçu e São Lourenço do Sul, no estado do Rio Grande do Sul, através das memórias de um casal de idosos, Vô Werno e Vó Eddy, filhos de imigrantes alemães. Utilizamos a tradição oral, Bosi (1994) e Vansina (2010), para o registro histórico das narrativas. Os comentários foram balizados, prioritariamente, por Freire (1987)

Ascites Is a Poor Prognostic Factor in Advanced Pancreatic Adenocarcinoma and May Be Undertreated: A Prospective Cohort Study.

INTRODUCTION: Pancreatic ductal adenocarcinoma is associated with significant morbidity and mortality as most patients present with advanced disease. The development of ascites has been associated with poor outcomes and further characterization and contemporary management strategies are needed. METHODS: A total of 437 patients enrolled in the Gastrointestinal Biobank at Cedars-Sinai Medical Center who had epithelial pancreatic malignancy were included in the prospective cohort group. Overall, 41.7% of patients included in this study developed ascites. Most patients with ascites (&gt;80%) had high serum-ascites albumin gradient ascites. In both univariate and multivariate analysis, a history of ≥1 form of chemotherapy was significantly associated with ascites. Estimated median overall survival in patients with ascites was significantly lower than in patients without ascites, 473 days vs 573 days, and ascites had a hazard ratio of 1.37. RESULTS: Patients with ascites who received diuretics and indwelling peritoneal catheter had an estimated median survival of 133 days from diagnosis of ascites, and those who received only the indwelling peritoneal catheter without diuretics had an estimated median survival of only 54 days. The estimated median survival from the diagnosis of ascites was 92 days, and the median time to puncture was 7 days. The median time from first tap to death was 45 days. DISCUSSION: The use of diuretics is lower than would be expected for patients with pancreatic ductal adenocarcinoma with elevated serum-ascites albumin gradient. Other therapies such as beta blockers should be investigated in this subset of patients. The etiology of ascites in these patients is poorly understood, and further research is needed to establish treatment guidelines and improve outcomes
