Aqueous phase reforming (APR) of glycerol over platinum supported on Al2O3 catalyst
(2016)The glycerol's APR reaction over 5% Pt/Al2O3 catalyst for H2 production in a batch reactor is investigated in the present work. The effect of the operating parameters, such as the: i) reaction time, ii) operating temperature, ... -
Biological activity of two new pyrrole derivatives against stored-product species: Influence of temperature and relative humidity
(2016)Members of the pyrrole group are likely to have interesting properties that merit additional investigation as insecticides at the post-harvest stages of agricultural commodities. In the present work, the insecticidal effect ... -
Effect of a simulated heat wave on physiological strain and labour productivity
(2021)Background: The aim of the study was to investigate the effect of a simulated heat-wave on the labour productivity and physiological strain experienced by workers. Methods: Seven males were confined for ten days in controlled ... -
Effect of temperature on the fecundity of Pezothrips kellyanus (Thysanoptera: Thripidae)
(2012)The reproductive biology of a citrus pest Pezothrips kellyanus (Bagnall) was studied at four constant temperatures (15, 20, 25, and 30°C) on lemon leaf discs, under laboratory conditions. Lifetime fecundity of mated P. ... -
Effects of salinity and temperature on the performance of Cymodocea nodosa and Ruppia cirrhosa: A medium-term laboratory study
(2019)The effects of salinity and temperature on the photosynthetic and growth performance of the seagrasses Cymodocea nodosa and Ruppia cirrhosa were studied to understand their local seasonality and distribution. Cymodocea ... -
Efficacy of low temperatures for the control of all life stages of Plodia interpunctella and Liposcelis bostrychophila
(2018)The insecticidal effect of low temperatures for the control of all life stages of two stored-product insects, Plodia interpunctella and Liposcelis bostrychophila, was evaluated under laboratory conditions. The temperatures ... -
The impacts of sun exposure on worker physiology and cognition: Multi-country evidence and interventions
(2021)Background: A set of four case-control (n = 109), randomized-controlled (n = 7), cross-sectional (n = 78), and intervention (n = 47) studies was conducted across three countries to investigate the effects of sun exposure ... -
Interference of weeds in vegetable crop cultivation, in the changing climate of Southern Europe with emphasis on drought and elevated temperatures: A review
(2018)It is challenging to predict the changes in weed flora that may occur because of changes in global climate. Limited data are available on the effect of climate change and drought conditions on weed flora and their ... -
Laboratory evaluation of five novel pyrrole derivatives as grain protectants against Tribolium confusum and Ephestia kuehniella larvae
(2017)Several naturally discovered or laboratory-synthesized pyrrole compounds have insecticidal, acaricidal and microbial properties. The novel sulfanyl 5H-dihydropyrrole derivatives exhibit certain antioxidant activities. ... -
Lifespan of a Ceratitis fruit fly increases with higher altitude
(2010)Variation in lifespan may be linked to geographic factors. Although latitudinal variation in lifespan has been studied for a number of species, altitude variation has received much less attention, particularly in insects. ... -
Monitoring of oxygen fluctuations in seabass cages (Dicentrarchus labrax L.) in a commercial fish farm in Greece
(2018)Dissolved oxygen and temperature were monitored in cages stocked seabass at a commercial fish farm in Greece during summer and autumn. During the first part of the study, October–November 2012, current velocity monitoring ... -
Natural ventilation of a greenhouse with ridge and side openings: Sensitivity to temperature and wind effects
(1997)An air exchange rate model of a Mediterranean greenhouse with ridge and side openings combining temperature and wind effects as driving forces of the natural ventilation was developed and tested on experimental data. it ... -
Overview of existing heat-health warning systems in Europe
(2019)The frequency of extreme heat events, such as the summer of 2003 in Europe, and their corresponding consequences for human beings are expected to increase under a warmer climate. The joint collaboration of institutional ... -
Performance analysis of a grid-connected photovoltaic park after 6 years of operation
(2019)The growth of renewable energy and especially photovoltaic energy in Greece is remarkable. There exist many grid-connected systems in Greek territory which have completed ten years operation. A challenging task for these ... -
Responses of the Mediterranean seagrass Cymodocea nodosa to combined temperature and salinity stress at the ionomic, transcriptomic, ultrastructural and photosynthetic levels
(2022)The Little Neptune grass Cymodocea nodosa is a key seagrass species in the Mediterranean Sea, forming extensive and patchy meadows in shallow coastal and transitional ecosystems. In such habitats, high temperatures and ...
