Heat Transfer has special importance in engineering applications. So, researchers have suggested different new idea to increase heat transfer and using nanofluid is one of these methods In recent years, new methods have been used. One of these methods is the use of nanofluids, ., because nanofluids have higher heat transfer potential than base conventional fluids. In this investigation effect o...

Energetic, highly-charged oxygen ions, Oq+ (q ≤ 6), are copiously produced upon laser field-induced disassembly of highly-charged water clusters, (H2O)n and (D2O)n, n ∼ 60, that are formed by seeding high-pressure helium or argon with water vapor. Arn clusters (n∼40000) formed under similar experimental conditions are found undergo disassembly in the Coulomb explosion regime, with the energies ...

Water transparency affects the thermal structure of lakes, and within certain lake depth ranges, it can determine whether a lake mixes regularly (polymictic regime) or stratifies continuously (dimictic regime) from spring through summer. Phytoplankton biomass can influence transparency but the effect of its seasonal pattern on stratification is unknown. Therefore we analysed long term field dat...

Two-phase heat transfer is experimentally examined through vertical small diameter tubes, D =1.45 and 2.8 mm using water under a pressure of 50 to 81 kPa and a natural circulation condition. The pool boiling correlation by Stephan-Abdelsalam and the thermosyphon boiling correlation by Imura, et al. predict the measured experimental data in the 2.8 mm tube with an error of -30%. A large heat tra...

The question of human resources is central to the success of VISION 2020 and of any health programme. The VISION 2020 global initiative document clearly spelt out what personnel was required and, more recently, the World Health Organization document on human resources for health care made recommendations on the type and number of people needed in order to meet all our objectives in global healt...

The purpose of this article is to introduce non-verbal tools as a way to initiate the psychosocial support response after a major disaster. The psychosocial interventions that follow the application of the Non Verbal Tool in its different configurations are based on the principle of fostering and strengthening the social and psychological attributes among the community members. The various psyc...

Family caregivers of persons following neurotrauma function as de facto extensions of our health care system. Their challenges may result in negative consequences for their physical and mental health, which directly impacts the well-being of their care-recipient. In this paper, we survey current practices in providing caregiver support, outline considerations for developing collaborative interv...

Objective The individually delivered Supervising for Home Safety (SHS) program improves caregivers' injury-related beliefs and supervision practices. The current randomized controlled trial used a group delivery in a community setting and assessed program impact, feasibility, and acceptance. Methods Caregivers of 2-5-year-olds were randomized to receive either the SHS or an attention-matched ...

Today climate change is one of the most important human concerns This fact affected human life in different ways .  one of the most important impacts of climate change is on crops yield so that change in temperature  regime  particularly maximum and minimum  temperatures  is noticeably change plants production . in this research , is considered to  impact of climate change on water requirement ...
