| ABSTRACT The growing use of Photovoltaic Solar Energy in Brazil, both in power plants and in distributed generation systems, brings with it a series of practical and technical questions that are not limited to the design and project of the systems. Environmental factors and resources related to the use, operation, maintenance, decommissioning and final disposal of the equipment and components that constitute them, should be taken into consideration, so that these systems maintain an adequate performance during their lifespan granting the safety for users, properties and avoid negative environmental impacts. Within the concept of Risk Analysis within the Life Cycle of these systems, the present study addresses a perspective of the growth of the use of Solar... |

| The aim of this study was to investigate the influence of image resolution manipulation on the photogrammetric measurement of the rearfoot static angle. The study design was that of a reliability study. We evaluated 19 healthy young adults (11 females and 8 males). The photographs were taken at 1536 pixels in the greatest dimension, resized into four different resolutions (1200, 768, 600, 384 pixels) and analyzed by three equally trained examiners on a 96-pixels per inch (ppi) screen. An experienced physiotherapist marked the anatomic landmarks of rearfoot static angles on two occasions within a 1-week interval. Three different examiners had marked angles on digital pictures. The systematic error and the smallest detectable difference were calculated from... |

| In this research the adaptation and validation of the Environmental Concern Scale (ECS) for Brazilian Portuguese and the environmental concerns of students were described. After being translated with the assistance of an expert teacher in Spanish language, the ECS was administered to two samples: one of university students (N=153) from Federal Institute of Education Goiano (IF GOIANO), Rio Verde campus, and another of public servants evaluators (N=13) from Federal Institute of Education, Science and Technology of Rondônia (IFRO), Colorado do Oeste campus. Content validity, reliability and construct validity were evaluated. Statistical properties obtained proved the quality of the measurement instrument of Environmental Concern. The agreement style of... |

| ABSTRACTAn investigation into the maintenance culture of industrial generators in the agro-based industries in South-West Nigeria has been carried out. The instruments used for this survey includes: interview, market survey direct observation and questionnaires. Investigation revealed that over 75% of the agro-based industries in the South-West town of Ibadan are predominantly medium scale in status with a carrying capacity of less than 550KVA electricity generating equipment. There is high level compliance (92.5%) tokeeping of daily maintenance record,negligence onlong time fuel keeping (up to 5 weeks at times), a greater degree of negligence inmean time to repairs (MTTR) on malfunctioned components and poor response time to servicing the generator at... |

| Social capital in the past two decades has emerged as a dominant paradigm in the various social science disciplines. However, its adoption by the different social science disciplines has led to multiple and often conflicting definitions of social capital. Some differences in the definition of social capital can be explained because scientists have included in the definition expressions of its possible uses, where it resides, and how its service capacity can be changed. This paper defends the social capital metaphor by pointing out that social capital has many important capital-like properties including service potential, durability, flexibility, substitutability, opportunities for decay (maintenance), reliability, ability to create other capital forms,... |

| The objective of this study was to determine the inter- and intra-examiner reliability of pain pressure threshold algometry at various points of the abdominal wall of healthy women. Twenty-one healthy women in menacme with a mean age of 28 ± 5.4 years (range: 19-39 years) were included. All volunteers had regular menstrual cycles (27-33 days) and were right-handed and, to the best of our knowledge, none were taking medications at the time of testing. Women with a diagnosis of depression, anxiety or other mood disturbances were excluded. Women with previous abdominal surgery, any pain condition or any evidence of inflammation, hypertension, smoking, alcoholism, or inflammatory disease were also excluded. Pain perception thresholds were assessed with a... |

| The gulf of Cariaco, Venezuela, is a rather isolated piece of coastal ocean where spatio-temporal variability has been measured. In 1986, three repeated surveys have been carried out in this gulf. The important differences in biomass estimates are attributed to sampling error only. The biological nature of this variability is studied. It is due to a high concentration of the biomass in a few schools and correlatively to the hit or the miss of these large schools, during the sampling. Structural information for predicting them is sought. Also, the number of schools per elementary sampling distance unit (ESDU) and the biomass in each school were measured by echointegration. It is found that there is no clear relation between these two variables. Thus their... |

| In 1992 the National Oceanic and Atmospheric Administration (NOAA) convened a panel of prominent social scientists to assess the reliability of natural resource damage estimates derived from contingent valuation (CV). The product of the Panel's deliberations was a report that laid out a set of recommended guidelines for CV survey design, administration, and data analysis. One of the Panel's recommendations was that CV surveys should employ a referendum approach. This method describes a choice mechanism that asks each respondent how they would vote if faced with a particular program and the prospect of paying for the program through some means, such as higher taxes. The Panel also recommended that CV referendum questions which commonly use only "for" or... |

| The understanding of how allocation decisions can maximise the economic returns to the community from water for irrigation has received little attention, but is a significant issue for regional councils, those interested in water allocation policy development, and for irrigated farmers. There is a tradeoff between the amount of irrigated area and the reliability with which it can be undertaken. Overseas studies have generated a curve with optimum levels of allocation which maximise the economic return to the community from the resource. The study on which this paper is based used a single case study to model the individual and regional economic outcomes for four scenarios of water allocation, using daily time step simulation models of the hydrological,... |
