“…The low RH values observed (Table 1) are due to the implementation of the experiment during the drought period, in addition to the fact that an atypical rainfall deficit occurred in 2014. This drought in the southeast of Brazil was due to climate change caused by a high-pressure system that blocked the Atlantic cold fronts (Mendes, 2014).…”

The thermal and luminous conditions in aviaries affect the production and quality of eggs. Thus, the aim of the present study was to evaluate the thermal and luminous environment of commercial laying hen aviaries equipped with compact fluorescent (CF) and light-emitting diode (LED) lamps and their influence on egg production and quality. The study was carried out in two commercial laying hen facilities with similar construction features and management. The first facility was illuminated with CF lamps and the second with LED lamps. The thermal environment was assessed via air temperature, air relative humidity, and enthalpy. The evaluated lamps provided a similar thermal environment in both facilities. The aviary equipped with LED lamps showed higher illuminance than the one equipped with a CF lamp. Production performance was evaluated through feed intake (FI), feed conversion (FC), mortality (M), and laying percentage (LP). Specific gravity (SG) was used to evaluate eggshell quality. The variables related to production performance and eggshell quality of laying hens raised in aviaries equipped with LED lamps were statistically equal (F-test, p > 0.05) to those raised in aviaries equipped with CF lamps. These results indicate that the replacement of CF lamps with LED lamps does not adversely affect the yield and quality of eggs.

O Brasil possui grande potencial de radiação solar devido a sua localização geográfica, sendo assim a energia solar fotovoltaica (ESFV) aparece como alternativa sustentável para produção de eletricidade. Dentre as aplicações da ESFV está o bombeamento de água para irrigação. Dessa forma, o presente trabalho tem como objetivo analisar o rendimento de um sistema fotovoltaico de bombeamento de água para irrigação de uma casa de vegetação localizada no Instituto Federal Fluminense Campus Campos Guarus, assim como dimensionar e implantar tal sistema nas dependências do campus. Este estudo foi dividido em quatro etapas: dimensionamento, montagem, monitoramento das grandezas físicas e elétricas e cálculo do rendimento do sistema. Para verificar as correlações existentes entre as variáveis irradiação solar, vazão, rendimento e temperatura ambiente aplicou-se o método de Análise de Regressão através do software BioEstat versão 5.3. A partir da metodologia proposta, foi possível verificar que o rendimento médio do sistema de bombeamento foi de 49,41%, atendendo a necessidade de irrigação. Além disso, observou-se que a irradiação solar influenciou tanto a vazão quanto o rendimento do sistema. Entretanto, a temperatura ambiente não apresentou influência na vazão e no rendimento. Sendo assim, os dados não foram conclusivos, necessitando de um maior período de medições para validar a relação das variáveis com a temperatura.
