A produção orgânica no município de Cacoal, RO: uma análise da dinâmica econômica e o desenvolvimento sustentável.

A preocupação com a segurança alimentar, qualidade de vida e a questão ambiental vem ao longo do tempo adquirindo uma dinâmica em escala global com novos hábitos alimentares e modos de produção. Com o objetivo verificar o desenvolvimento produtivo e sua viabilidade comercial diante da implantação de sistemas orgânicos na associação dos produtores do município de Cacoal, RO buscou-se analisar e caracterizar as relações comerciais e sociais que se estabelece entre o produtor e consumidor sendo identificados os diferentes cenários como: produção, distribuição e comercialização no município, através do método de pesquisa com a identificação dos principais meios e espaços de comercialização e, a realização de entrevistas com os principais membros da associação e feirante envolvidos no processo. Conclui-se que diante dos obstáculos a serem superados, a produção e a comercialização agroecológica apresenta possibilidades de expansão no município

The phenomenology of depression

The phenomenological method, characterized by the suspension of judgment (epoché), has helped analyzing the subjective experience of patients affected by mental disorders. Psychiatry, dealing with the human being itself in its complexity and unicity, is placed between the biological positivistic attempt, for which the symptoms of mental illness are a mere consequence of brain dysfunctions and the phenomenological-existential approach, inclined to consider the symptoms as meaningful phenomena of the person’s subjective experience. Eugène Minkowski, Ludwig Binswanger, Arthur Tatossian, Kimura Bin, Henri Maldiney and Hubertus Tellenbach are fundamental authors in the phenomenological psychopathology of depression; they described the alterations of the lived time, space, body and others experienced by the depressed. Starting from the main theoretical contributions of the authors, we will focus on the psychopathology and discuss the key themes of clinical depression: guilt, poverty and hypochondriasis. Finally we will focus on the typus melancholicus construct

Shortest path with acceleration constraints: complexity and approximation algorithms

We introduce a variant of the Shortest Path Problem (SPP), in which we impose additional constraints on the acceleration over the arcs, and call it Bounded Acceleration SPP (BASP). This variant is inspired by an industrial application: a vehicle needs to travel from its current position to a target one in minimum-time, following pre-defined geometric paths connecting positions within a facility, while satisfying some speed and acceleration constraints depending on the vehicle position along the currently traveled path. We characterize the complexity of BASP, proving its NP-hardness. We also show that, under additional hypotheses on problem data, the problem admits a pseudo-polynomial time-complexity algorithm. Moreover, we present an approximation algorithm with polynomial time-complexity with respect to the data of the original problem and the inverse of the approximation factor ϵ. Finally, we present some computational experiments to evaluate the performance of the proposed approximation algorithm

Egg hatching at different temperatures and relative humidities in Idaea inquinata (Scopoli) (Lepidoptera: Geometridae)

Idaea inquinata (Scopoli) feeds mainly on dried plants, nevertheless, it is also a potential pest of stored products as it is able to develop on cereal products. The few references on the biology of this species do not deal with the influence of temperature and relative humidity on egg hatching. To fill this gap, groups of 100 eggs, 24-48 hours old, were exposed to five constant temperatures (17, 21, 26, 29 and 34±1°C), two relative humidities (35 and 70±5%) and a photoperiod of 0:24 (light:dark); ten tests were carried out. Each test was replicated four times and egg hatching was observed daily. The highest mean number of hatched eggs was observed at 26 and 29±1°C, 70±5% r.h. with 91.5 and 91.0 eggs, respectively. The lowest mean number of hatched eggs was 61.5 observed at 17°C and 70±5% r.h. The mean numbers of hatched eggs, 83.5, 77.5, 78.5 and 79.8 were similar at 21, 26, 29 and 34±1°C, 35±5% r.h., respectively. Eggs hatched between the sixth and the eighth day at all the temperatures tested, except for 17±1°C and 35±5% r.h., where hatching started on the twelfth day. At this temperature, the duration of the hatching period increased with increasing humidity: 11 d at 35% r.h. and 15 d at 70% r.h.

Recuperação de Mata Ciliar em Ouro Preto do Oeste, estado de Rondônia, Brasil.

Este trabalho foi realizado na bacia do rio Boa Vista localizada no município de Ouro Preto do Oeste, Rondônia, com o intuito de avaliar o desenvolvimento de um plantio de espécies arbóreas na área de mata ciliar. A recuperação desta bacia se deu mediante acordos firmados entre o poder público Estadual e a sociedade envolvida, a partir daí vários produtores se engajaram no projeto, visto que o rio é muito importante na região e também é fonte de captação da água que abastece a cidade. Foi observado a área de um produtor envolvido neste processo. No caso em estudo foram encontradas 13 espécies, 11 famílias e 92 indivíduos plantados e nativos, com grande chance de sobrevivência nas parcelas.Resumos do VIII Congresso Brasileiro de Agroecologia.

The impact of early-life stress in the development and course of bipolar disorder: Mechanisms and implications

Traumatic events experienced throughout the different stages of childhood and adolescence are frequent circumstances with a detrimental impact on the physical and psychological health of the individual. A growing body of evidence shows the trauma-related effects on the hypothalamic-pituitary-adrenal axis, the sympathetic nervous system, the serotonin system, the immune system, on brain development, structure, and connectivity. Interestingly, a relation was found between early life stress and Bipolar Disorder: the patients who were exposed to childhood trauma showed a worsened course of the disorder with poor clinical and psychopathological factors. According to the kindling hypothesis, early environmental stressors interact with the genetic susceptibility through epigenetic mechanisms, making the subject more vulnerable to milder stressors, and lowering the threshold for the occurrence of subsequent mood episodes. Understanding these processes is crucial to the discovery of new targets of treatment to reduce or, possibly, revert the effect of early life stress on bipolar disorder
