Assessment of water bodies of united arab emirates coastal sabkhas as potential sites for natural salinity gradient solar ponds
( ASCE - American Society of Civil Engineers , 2008 , Article)Increasing population and growing demands from both agriculture and industry in the United Arab Emirates (UAE) necessitate the need to provide inexpensive fresh water. The only feasible source of such water is desalination. ... -
The association between serum cortisol, thyroid profile, paraoxonase activity, arylesterase activity and anthropometric parameters of undergraduate students under examination stress
( SAGE , 2021 , Article)Stress caused due to examinations during any degree program and at any educational level has been observed at all levels so the present study was conducted to investigate the stress related to final examination in undergraduate ... -
Associations of plant functional diversity with carbon accumulation in a temperate forest ecosystem in the Indian Himalayas
( Elsevier B.V. , 2019 , Article)Carbon accumulation is the capacity of the forest to store carbon in trees, litter and soil, together contributing to climate regulation. Plants differ in their potential to capture, store and release carbon. Consequently, ... -

Background invertebrate herbivory on dwarf birch (Betula glandulosa-nana complex) increases with temperature and precipitation across the tundra biome
( Springer Verlag , 2017 , Article)Chronic, low intensity herbivory by invertebrates, termed background herbivory, has been understudied in tundra, yet its impacts are likely to increase in a warmer Arctic. The magnitude of these changes is however hard to ... -
Benthic marine algae of the arabian gulf: A critical review and analysis of distribution and diversity patterns
( Schweizerbart Science Publishers , 2014 , Article)The Arabian Gulf is an extremely inhospitable and physiologically-stressful environment for marine organisms since they are exposed to the widest range and the highest sea temperatures in the world, as well as high salinities. ... -
“Beyond the Source of Bioenergy”: Microalgae in Modern Agriculture as a Biostimulant, Biofertilizer, and Anti-Abiotic Stress
( Multidisciplinary Digital Publishing Institute (MDPI) , 2021 , Article)Microalgae are photoautotrophic organisms with high commercial potential. Extracts from microalgae are extensively used in crop cultivation, mainly because they possess growth-promoting properties, coupled with their ... -
