The hypothesis that Peruvian stratocumulus play an important role on both the annual mean and annual variations of sea surface temperature (SST) in the eastern equatorial Pacific is examined. The problem is addressed by performing sensitivity experiments using the University of California, Los Angeles, coupled atmosphere– ocean GCM with different idealized temporal variations of stratocumulus i...

The addition of mist to a flow of steam or gas offers enhanced cooling for many applications, including cooling of gas turbine blades. The enhancement mechanisms include effects of mixing of mist with the gas phase and effects of evaporation of the droplets. An impinging mist flow is attractive for study because the impact velocity is relatively high and predictable. Water droplets, less than 1...

The surface area of a photonic crystal biosensor is greatly enhanced through the incorporation of a porous TiO2 film possessing the structure of nanorods into the device. The film is deposited by the glancing angle deposition technique in an e-beam evaporation system. The sensitivity of high surface area sensors is compared with sensors without the high surface area coating. Results for detecti...

The solubility behaviour of drug is one of the most challenging aspects in formulation development. Thus a greater understanding of dissolution and absorption behaviour of drug with low aqueous solubility is required to successfully formulate them into more soluble and hence bioavailable drug product. Therefore different approaches are being explored to enhance the solubility of poorly water so...

at the first step cufe2o4 nanoparticles were synthesized by a fast and facile microwave method. the obtained nanoparticles and modified carbon nano tubes were added to poly styrene matrix. the products were characterized through fourier transform infrared spectroscopy, x-ray diffraction, and scanning electron microscopy. vibrating sample magnetometer shows nanoparticles exhibit ferromagnetic be...

The idea that the corona is at least in part supplied by chromospheric evaporation in loop “micro-events” is quantified in terms of the power requirements of evaporation mechanisms, using recent analyses of data on such events in high temperature EUV lines from the SoHO EIT instrument. Estimates are derived for the pre-event and event values of loop density and temperature and it is shown, usin...

Abstract. In a warming climate, periods with lower than average precipitation will increase in frequency and intensity. During such periods, known as meteorological droughts, the decline annual runoff may be proportionally larger corresponding precipitation. Reasons behind this exacerbation of deficit during dry remain largely unknown, challenges predictability when occur future how intense it ...

Enhancement of the rate boiling heat transfer, a critically significant need across range industrial transport processes, can be achieved by introduction surface microstructures. However, precise mechanism such enhancement is not definitively understood. We establish microlayer evaporation from imbibed liquid layer underneath growing vapor bubbles as key in transfer coefficient for microstructu...
