Estimation of Ozone Trend in Central Greece, Based on Meteorologically Adjusted Time Series
(2012)
Data referring to an approximately 8-year period (1999-2007) are analyzed in order to estimate the trend of the daily maximum hourly value of ozone concentration at the east coast of central Greece, where the summer ...
Maximum urban heat island intensity in a medium-sized coastal Mediterranean city
(2012)
This paper studies the maximum intensity of the urban heat island (UHI) that develops in Volos urban area, a medium-sized coastal city in central Greece. The maximum temperature difference between the city center and a ...
Improvement of greenhouse microclimate distribution by means of air mixing fans
(2012)
The objective of this work was to experimentally investigate the influence of air mixing fans on air temperature and humidity distribution in an arched roof greenhouse. The greenhouse was occupied by a tomato crop and ...
Microclimate of a pepper crop under screenhouse conditions
(2012)
In the present study, the influence of three different shading nets with different colour, shading intensity and porosity on the screenhouse and crop microclimate was experimentally investigated. The experiments were carried ...
Differences in required structural efficiency of standard commercial steel greenhouses among EU countries: A hellenic experience
(2012)
Since the climate and seismic conditions vary significantly among European countries (and sometimes even in different areas of the same country) the European Standard for the design and construction of greenhouses for ...
Solar radiation distribution in screenhouses: A CFD approach
(2012)
In this paper the effect of solar radiation distribution in a typical screenhouse was numerically investigated, taking into account the thickness and aerodynamic properties of the screen and its spectral, optical and thermal ...
Performance test of a Na+ accumulation model as part of a decision support system for closed hydroponic systems management
(2012)
The recycling of greenhouse effluents in soilless cultivation systems is environment-friendly, since the waste of water and the disposal of nutrients to the environment is drastically reduced or even eliminated. However, ...
Evaluation of crop reflectance indices for greenhouse irrigation scheduling
(2012)
Development of direct, non-contact, non-destructive methods for irrigation control purposes is of great interest. The present work deals with the evaluation of reflectance indices for irrigation control in greenhouse ...
Case studies of a modified biological simulator (TOMGRO) according to short cropping period
(2012)
The aim of this work was to perform a sensitivity analysis of a modified biological simulator (TOMGRO) in tomato crop during winter period. The modified biological simulator (TOMGRO) that used for case studies of the ...
