| 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... |

| Saffron is an herb plant and it propagated by corm. After 6 or 7 years, saffron corms should be picked up from the underground, graded and re-cultivated in the new field. Determination of appropriate lifting method, packaging and storage of saffron corms are necessary to reduce the falling of germination and maintained the corms quality. In this research, the effects of soil moisture content during lifting, packaging methods, storage temperature and storage period on corms waste, saffron yield, dried leaves weight and corms proliferation were investigated. Statistical analysis was done on randomized complete block design applying the analysis of variance (ANOVA). The results showed that the increasing of storage period, from 1 to 3 month, increased the... |

| 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... |

| A new method is presented to estimate individuals’ (1) age at maturation, (2) energy acquisition rate, (3) energy expenditure for body maintenance, and (4) reproductive investment, and the multivariate distribution of these traits in a population. The method relies on adjusting a conceptual energy allocation model to individual growth curves using nonlinear mixed-effects modelling. The method’s performance was tested using simulated growth curves for a range of life-history types. Individual age at maturation, energy acquisition rate and the sum of maintenance and reproductive investment rates, and their multivariate distribution, were accurately estimated. For the estimation of maintenance and reproductive investment rates separately, biases were observed... |

| We present a Dynamic Energy Budget (DEB) model for the eastern oyster, Crassostrea virginica, which enables the inclusion of salinity as a third environmental variable, on top of the standard foodr and temperature variables. Salinity changes have various effects on the physiology of oysters, potentially altering filtration and respiration rates, and ultimately impacting growth, reproduction and mortality. We tested different hypotheses as to how to include these effects in a DEB model for C. virginica. Specifically, we tested two potential mechanisms to explain changes in oyster shell growth (cm), tissue dry weight (g) and gonad dry weight (g) when salinity moves away from the ideal range: 1) a negative effect on filtration rate and 2) an additional... |

| This work presents the experience of the Laboratory of Arthropods at Instituto Butantan, which maintains scorpions in captivity in order to obtain the venom used in the production of anti-arachnid serum. Between 1993 and 2000, the laboratory received 24.781 specimens of Tityus serrulatus in order to obtain poison for the production of anti-scorpion serum. In the first extraction, performed by electrical stimulation, the animals gave an average quantity of 0.4 mg venom per specimen. Animal acquisition and involved professional safety are considered. In addition, the captivity, handling and feeding techniques are described, as well as the method and equipment used for venom extraction. It shows the importance of regular campaigns, offering information to the... |
