Using solar energy through photovoltaic systems implementation in an agricultural household leads to the increasing of it’s efficiency, to optimizing energy balance thus implying the decreasing of the primary energy costs. The solar energy refers to a renewable energy source that is produced...

When choosing policy mechanisms to design and deploy energy policies, policymakers typically seek cost-effective ones, linking cost effectiveness to the lowest cost of support for RES-E generation and/or consumer costs. The objectives of this paper are to analyze the cost-effectiveness of...

Processes of regional economic integration have been shaping the economic relations between countries significantly during the last decades. In addition, an increasing integration of the national economies into the global economy has affected these economic relations, too. In an effort to...

We review the disease ecology and bioeconomic literature on managing wildlife disease problems, and we also describe how wildlife disease problems relate to other health and resource problems. The disease ecology literature advocates managing populations relative to fixed ecological thresholds...

This paper provides an information technology perspective of energy that can help explain and promote more environmentally friendly energy sources. Following the equation energy equals mass times velocity squared (E = m * v2), a source 10 times more massive will produce 10 times more energy, but...

En la primera parte del estudio se denota la importancia que, desde el punto de vista financiero, tiene el concepto del costo del uso del capital en la situación de cualquier organización; luego se presenta una breve reseña del sector avícola y su importancia en la economía colombiana, como...

La participación de los profesionales de diversas disciplinas del agro en los procesos de reconversión sustentable de los agroecosistemas en Colombia, es factor clave para el desarrollo de la nueva agricultura que el país necesita frente a los problemas ocasionados por las inadecuadas...

Traffic accidents with wild boar have increased rapidly over the last years in Sweden. This paper calculates and predicts costs of current and future accidents, totally and for different Swedish counties, based on estimates of wild boar populations. A logistic population model is assumed, and...

The El Niños Southern Oscillations (ENSO) is a periodical phenomenon of climatic interannual variability which could be measured through either the Southern Oscillation Index (SOI) or the Sea Surface Temperature (SST) Index. The main purpose of this paper is to analyze these two indexes in...
