Although, that the solar energy is important for life continuity, there is need to protect large buildings from these radiations in summer and if the buildings are permitted to take these radiations, the cost of cooling will be too much. One of the most effective methods used to solve this problem is to coat buildings with specific pigments that reflect the solar infrared radiation. This wo...

During recent years, there was growing demand in using microalga valuable products such as β-carotene in health care. β-Carotene has anti-cancer and anti-aging properties for human. In Dunaliella salina cells, β-carotene has a major protecting role for biomolecules, when the production of reactive oxygen species elevated. In the present study, we investigated the influence of the four most effe...

soil-dwelling mites and among them gamasina (acari, mesostigmata) are widely distributed in soils, rich in species and have great ecological significance in the respective ecosystems. a survey was conducted to study laelapidae (mesostigmata) mites in ahwaz (khuzestan province), iran during 2010-2012. samples were taken from soil and litters and then mites extracted using berlese funnel, cleared...

Introduction: To present and assess a newly designed autoclavable, reusable tube shield for an endotracheal tube (ETT) during laser laryngeal surgery.   Materials and Methods: This study included patients scheduled for endolaryngeal laser surgery. A carbonated stainless-steel hemisphere shield (~1.5×0.6 mm) connected to a silk thread passing through a hole in its middle near upper edge was ...

Although B-carotene has been considered to be a key cancer preventive agent in green and yellow vegetables, other types of carotenoids, such as a-carotene, may also contribute to anticarcinogenic action, since these carotenoids usually coexist with/~-carotene and are detectable in human blood and tissues. In this study, we compared the inhibitory effect of natural a-carotene, obtained from palm...

Introduction: The geologic features “shield fields” and “shield plains” (or “shield terrain”) have been used by a number of Venus researchers and authors of Venus geologic quadrangle maps. However, there has been occasional confusion concerning the two terms and the geologic units they define. Stratigraphic interpretation may vary due to the identification of clusters of small shields as either...
