Climatic conditions inside nuclear reactor containments - Monitoring campaign
… radioactive nuclides. During operation the climatic conditions inside the reactor containment can be harsh, with temperatures over 50 °C and low relative humidities (RH). Knowledge about the condition in the containment and in the concrete structures is thereby important in order to evaluate …

Comprehensive Evaluation of Asphalt Mixtures in Arid Climatic conditions
… in the asphalt-wearing course in Kuwait's arid climatic conditions. The extreme conditions of Kuwait and poor asphalt mix design characteristics have further accelerated the raveling and deterioration of the in-service asphalt pavements. Combating this issue requires sophisticated asphalt …

The effects of human disturbance and climatic conditions on breeding Cassin’s auklets
… studied the effects of adverse climatological conditions on breeding success of this species. First, using some biometrics of the individuals captured, I tested a method for aging Cassin’s auklet based on the iris colour. My results corroborate what was proposed before, juveniles have a …

Impacts of Reservoir Operations with Extreme Hydrologic and Climatic Conditions on Fish Sustainability below Shasta Lake
… will be effective under uncertain future conditions such as climate change and extreme hydrologic conditions not observed in the historical record. This study examines the ability of providing artificial cold water habitat by coupling a stochastic model for model input generation with a …

Flat-Plate Solar Collectors for Water Heating with Improved Heat Transfer for Application in Climatic Conditions of the Mediterranean Region
The aim of this research project is to improve the thermal performance of passive flat plate solar collectors using a novel cost effective enhanced heat transfer technique. The project work focuses on the process of energy conversion from the collector to the working fluid. This is accomplished by …

Assessing surface and underground cooling methods, coupled to efficient ventilation systems to improve the climatic conditions in deep and hot mines
… would be sufficient to provide adequate work conditions, or a cooling system is needed. Many times, the climatic conditions in the production areas can be improved by simply redesigning the auxiliary ventilation system. Ventilation simulations show that by changing the fan arrangement from …

Molecular characterisation of XvVTC2, a gene coding for a GDP-L-galactose phosphorylase from Xerophyta viscosa
… plants can withstand highly variable and harsh climatic conditions. This makes them ideal candidates to elucidate possible mechanisms which can be used to adapt crop plants to tolerate variable climatic conditions associated with climate change.

Biogeography, ecology and conservation of Paradisaeidae: Consequences of environmental and climatic changes
… their conservation. For example, under future climatic conditions and considering loss of forest cover, Astrapia nigra may face extinction within just 2-4 decades. Generally, under future climatic conditions, BOP distributional areas decrease. Relatively few BOP species face distributional …

Soil Slope Failure Investigation Management Systems
Highway slopes are exposed to environmental and climatic conditions, such as deforestation, cycles of freezing and thawing weather, heavy storms etc. Over time these climatic conditions can influence slope stability in combination with other factors such as geological formations, slope angle and …

Stable carbon and oxygen isotope investigation of Pleistocene growing-season paleoclimate using tree-ring cellulose from the Missinaibi Formation, Adam Creek, James Bay Lowland, Canada
… rings provide a record of seasonal and annual climatic conditions such as precipitation and temperature. We analyzed stable isotopes of carbon (δ13Ccellulose) and oxygen (δ18Ocellulose) in early-wood and late-wood of five conifer sub-fossil wood samples from the Missinaibi Formation, which …

Effects of climate and forest management on the water and nitrogen status of European beech regeneration and understorey vegetation
… present study assessed the effects of different climatic conditions on the nitrogen and water status of natural beech regeneration grown in managed (thinned) and not managed (control) stands in a forest in Southern Germany. A SW-exposed site, characterized by low water availability and high …

Too hot to handle: how Martial Eagles (Polemaetus bellicosus) manage the heat in the Kruger National Park, South Africa
… However, how species react to changing climatic conditions can vary between species, with some species better able to adapt to such changes than others, either through physiological processes or behavioural adaptation. Changing climatic conditions can alter a species' ability to acquire …

Critical Moisture Conditions for Mould Growth on Building Materials
… different constructions are exposed to different climatic conditions. To minimise the risk of microbial growth, building materials should be chosen that are tolerant to the expected climatic conditions. In this study, the critical moisture levels for ten building materials were evaluated in …
