Balanço de energia de fluxo de CO2: cerrado da floresta estadual de Assis

Based on climatological data and energy flow, this paper analyzes the behavior observed in microclimatic an important remnant of cerrado in the São Paulo State. The seasonal climate is well marked, in the study area, with two climatic periods (one dry and one wet). The vegetation presents physiology as a function of water availability and the local thermal conditions and can be seen marked changes in the landscape due to the more or less presence of solar radiation. It’s important to understand the ecosystems behave in the context of global change. It has gained the attention of many researchers in the world.

Utilização de análise de agrupamento na caracterização do perfil agrícola e climático da região sudeste do Estado de Mato Grosso

The multivariate analysis grouping was used to characterize the productive and climate profile of southeastern of Mato Grosso state. This technique allowed the junction of similar micro regions from characteristics of productivity and climatic, without the need for the assumption of the number or structure of the groups. Cluster analysis allowed the design of a mosaic of spatial heterogeneity regions. It established different profiles in the composition of groups, joining the more traditional in the culture of a species, or more productive, or those for the development of a particular culture. The results obtained by estimation of the climatic parameters and the multivariate procedures enabled the provision of systematic information that will allow farmers to better decision-making on the competitiveness and maintaining the flow of investment in agricultural sector southeastern Mato Grosso.

O clima em sua regulamentação político-econômica: o acordo de Copenhague - COP 15

We know that the Earth goes through natural cycles that influence its climate and the development of their societies. In recent decades, climate changes and nature began to call world attention to the unbridled exploitation that was carried by the current economic system, causing unrest among scientific, social, political and economic world. The theory that man causes a warming in global temperatures by the release of greenhouse gases made the headlines of major newspapers in the world. From there, it was only a matter of time before environmental concerns became ownership of capital by its excessive appropriation. The fear of nuclear threat by the bombs of Hiroshima and Nagasaki left in fanfare the world, which together with the devastating impact of the exploitation of man and nature gave birth to the Environmental Revolution, a way of trying to change the development patterns of the time and behavior of the population. However, based on the historical form of capitalist domination, this was another measure that was apossada the economic system being transformed into economic value and political exchange. The origin of the conventions, meetings, conferences, parliaments set up to discuss environmental issues, eventually became forums of political and economic talks focused on environmental governance, valuing an asset that is public and everyone. Environmental and climate issue now has a value, thus turning the agenda on the agenda of the United Nations (UN) for its political and economic regulation in the form of global agreement. Given the need for understanding the climate issue, was born the Conference of the Parties (COPs), a regulatory body for climate negotiations, surrounded interests, complexities, conflicts and disagreements between the parties countries, which becomes clear when we analyze their agreements...

Efeito das condições ambientais no nível de ruído emitido por leitões

Objetivou-se, com este trabalho, avaliar a influência das variáveis ambientais nos níveis de ruídos emitidos por suínos e quantificar as faixas em dB comparativamente às condições de conforto térmico estabelecidas pela literatura. O experimento foi conduzido em câmara climática, onde foram alojados cinco leitões em fase de creche, submetidos à variação na temperatura ambiente de 20°C a 38°C e umidade relativa de 50% a 80%. Decibelímetros foram instalados para o registro dos níveis de ruídos e sensores dataloggers para os dados de temperatura e umidade relativa. O nível de atividade foi utilizado para quantificar a movimentação dos animais por intermédio de análise de imagens. Análises de correlação e regressão foram aplicadas nos dados para análise estatística. As variáveis ambientais influenciam na emissão de ruídos pelos leitões quando expostos a diferentes condições térmicas. Os níveis de ruídos foram estabelecidos em faixas de acordo com a condição térmica a que animais foram submetidos. Para a condição de conforto (20 a 23°C), níveis de ruídos na faixa de 70 a 75dB; condição de alerta (23 a 30°C), níveis de ruídos na faixa de 60 a 70dB e para condição de estresse térmico (acima de 30°C), na faixa de 55 a 60dB.

La cadena de oscilaciones del clima en el pasado de Canarias

[ES] En Canarias están las pruebas de la existencia de una cadena climática en esta parte del Globo: eslabones de clima de pleno glacial árido-frío (dunas), de clima interglacial temprano árido-sub-húmedo (polvo), de clima cálido y húmedo de máximo interglacial (depósitos marinos), de clima de transición árido-templado (calcretas) y otra vez clima glacial-árido-frio. Esta cadena se desarrolla desde hace cinco millones de años inicialmente en adagio (lento y majestuoso) para pasar sucesivamente a un andante, allegro y vivace. Este largo proceso está medido desde 1981 hasta este año de 2013 por todas las dataciones existentes: K/Ar en lavas, U/Th en fósiles marinos y terrestres, C14 tradicional y en acelerador atómico en fósiles, OSL en dunas, Series de U en corales, además de ensayos sobre aminoácidos e isótopos de Sr en marcha. Todo ello con una espléndida y sorprendente información paleontológica.
