Energy balance in a greenhouse: temperature and humidity monitoring
(Corporación Universidad de la Costa, 2021)
Sistema microcontrolado para estufas
(Universidade Tecnológica Federal do ParanáCuritibaBrasilEngenharia de Controle e AutomaçãoUTFPR, 2017-12-06)
This work is a culminating study support the completion of the degree course; it presents the feasibility of building an automated greenhouse system for the production of crops. The greenhouse here that was developed as a ...
Crop production in controlled-environment greenhouses with an integrated solar desalination system
(1999)
The burgeoning world population requires intensified efforts to increase food production, especially in tropical and subtropical regions. The authors report below on a controlled-environment saltwater greenhouse with ...
Equations for estimation of solar UV, PAR and IV in polyethylene greenhouse
(Fundacion General Univ Politecnica Madrid, 2014-01-01)
In this work are shown annual and monthly evolutions of (H) over bar (IN)(G), (H) over bar (IN)(UV), (H) over bar (IN)(PAR), (H) over bar (IN)(IV) solar radiations and (K) over bar (UV), (K) over bar (PAR) e (K) over bar ...
Characteristics of WWTP sludge after drying in greenhouse for agricultural purposes
(IWA PUBLISHINGLONDON, 2012)
The sludge generated by sewage treatment which meets regulatory standards can be used in agriculture. With this understanding, the focus of this study is the evaluation of the agricultural characteristics and inorganic ...
Study using a CFD approach of the efficiency of a roof ventilation closure system in a multi-tunnel greenhouse for nighttime microclimate optimization
The thermal efficiency of naturally ventilated greenhouses is limited due to the permanent exchange of air through the vents, especially during the night hours. The objective of the work consisted in evaluating a system ...
Improved pollination efficiency and reduced honey bee colony decline in greenhouses by allowing access to the outside during part of the day
(2018-10-01)
Although honey bees are efficient pollinators of many crops cultivated in greenhouses, it is difficult to maintain colony strength and consequently pollination efficiency. Many bees die under greenhouse conditions and the ...
