Small heat shock protein beta-1 (HSPB-1) plays an essential role in the protection of cells against environmental stress.Elucidation of its molecular, structural, and biological characteristics in a naturally wild-type model is essential. Although the sequence information of the HSPB-1 gene is available for many mammalian species, the HSPB-1 gene of Arabian camel (Arabian camel HSPB-1) has not ...

The recent first-field phase of Indian Ocean Experiment has provided various types of aerosol data over the Arabian Sea, the Bay of Bengal and the Indian Ocean. Using optical sensors on-board numerous satellites, global aerosol parameters have been estimated by many workers. In this communication, we have used IRS P4 OCM data to retrieve the aerosol parameters over the Arabian Sea and the Bay o...

More than 2000 measurements of atmospheric and dissolved methane (CH4) were performed in the central and northwestern Arabian Sea as part of the German JGOFS Arabian Sea Process Study during three cruises in March, May/June, and June/July 1997. Mean CH4 saturations in the surface waters of the central Arabian Sea were in the range of 103-107%. Significantly enhanced saturations were observed in...

The lack of a standard muzzle print database is a challenge for conducting researches in Arabian horse identification systems. Therefore, collecting a muzzle print images database is a crucial decision. The dataset presented in this paper is an option for the studies that need a dataset for testing and comparing the algorithms under development for Arabian horse identification. Our collected da...

Evidence of Earlyto Mid-Cryogenian (c. 780 Ma and c. 740 Ma) glacial activity is summarized for the northern Arabian–Nubian Shield (ANS), including structural framework, stratigraphy, lithological descriptions and relationships with younger and older units, banded iron formation chemostratigraphy, other characteristics, geochronological constraints, and discussion. The ANS is a broad tract of j...

The Saharan Metacraton is a poorly known tract of pre-Neoproterozoic continental crust that occupies the area between juvenile Arabian Nubian Shield, in east, and Tuareg Shield to west. Neoproterozoic orogenesis (i.e. Oubanguides East African orogenies) affect west, south east metacraton, respectively, which led deformation, emplacement igneous bodies, localised episodes rift-related magamatism...

Abstract The growth of continental crust through melt extraction from the mantle is a critical component chemical evolution Earth and development plate tectonics. However, mechanisms involved remain debated. Here, we conduct petrological geochemical analyses on large (up to 5000 km 2 ) granitoid body in Arabian-Nubian shield near El-Shadli, Egypt. We identify these rocks as largest known plagio...
