Climate change and its possible impacts on the environment and socio-economic systems now constitute the most important environmental problem facing mankind in the 21st century. Climate change will increase poverty and hardship, endanger food security, destabilize economies, decrease food and water and create social insecurity in many countries and undermine our goals for achieving sustainable ...

chemical denaturation and thermal denaturation of13-lactoglobulin a (f3 — lga) in the absenceand presence of various concentrations sugar osmolytes and polyols were measured bymonitoring changes in the absorption coefficients at ph 2.0. it has been observed that agd°(h20), (gibbs free energy change in absence of denaturant at 25 °c) of f3-1ga in the presenceof 10% (w/v) trehalose, sucrose, sorb...

passive solar systems such as solar chimneys need solar radiation in order to work. therefore, they cannot present stable natural ventilation when solar energy vanishes: to have a more robust and stable condition, solar energy should be stored during the day and released back during the night. phase change materials can save additional thermal energy during the day and release it during the nig...

Motivation Policies to promote solar photovoltaic (PV) adoption have been gaining momentum throughout the world, as concerns over global climate change and national security externalities continue to grow. In the US: 30% solar energy federal investment tax credit. Yet we understand very little about the process of diffusion of this technology.

Studies of the effects of climate changes on marine biofouling have mainly focused on the effects of temperature increase, but a decrease in the level of solar radiation could also influence the establishment and persistence of fouling species. To test if decreased solar radiation and/or increased temperature influenced marine fouling communities, solar radiation, and temperature were manipulat...

increasing of energy demand and decreasing of water resources, could make the future energy production as a big challenge. climate change is one of the main reasons for water resources limitation. future precipitation and air temperature, change hydrological conditions and directly effect on the hydropower production. for showing the future condition and making it possible to manage the hydropo...
