Question: What is the basis for geographic variation in microhabitat use in fence lizards? Hypothesis: Population differences in microhabitat use reflect behavioural plasticity rather than genetic or experiential differences. Organisms: Western fence lizards (Sceloporus occidentalis). Field site: Three sites (desert, valley, and mountain) in southern California, USA. Methods: We compared habita...
Cultural heritage has always been the focus of many civilizations and therefore, it needs to be preserved for future generations. From prehistoric times, when grandeur and beauty were the aims of architecture, stone was the most widely used durable material. Biodeterioration of the stone monuments, one of the most important causes for the loss of the cultural heritage, is defined as any undesir...
Waste management is a complex and detailed process that involves evaluation of certain important factors, such as a geological, geotechnical, hydrological, hydrogeological, climate, urban management, environmental, along with social, cultural, and psychological parameters. Unfortunately, in Iran, there is minimal evaluation of initial parameters and in some cases even don’t exist. The purpose o...

This study investigated the electronic properties of antiferromagnetic UBi2 metal by using ab initio calculations based on the density functional theory (DFT), employing the augmented plane waves plus local orbital method. We used the exact exchange for correlated electrons (EECE) method to calculate the exchange-correlation energy under a variety of hybrid functionals. Electric field gradients...
