In the present study, the main objective is to evolve a correlation to predict liquid-liquid two-phase heat transfer coefficients in a spiral plate heat exchanger. Experimental studies were conducted in a spiral plate heat exchanger using the liquid-liquid two-phase system of water-diesel in different volume fractions and flow rates as the cold fluid. Experiments were conducted by varying the v...

Sonic hedgehog (Shh) secreted from the axial signaling centers of the notochord and prechordal plate functions as a morphogen in dorsoventral patterning of the neural tube. Active Shh is uniquely cholesterol-modified and the hydrophobic nature of cholesterol suggests that it might regulate Shh spreading in the neural tube. Here, we examined the capacity of Shh lacking the cholesterol moiety (Sh...

BACKGROUND Healthcare liquid wastes are the reservoirs of harmful infectious agents such as the pathogens and multiple drug resistant microorganisms. Potential infectious risks include the spread of infectious diseases and microbial resistance from health-care establishments into the environment and thereby posing risks of getting infections and antibiotic resistance in the communities. OBJEC...

Different screening methods namely, hemolytic assay (HA), modified drop collapse (MDC), tilted glass slide (TGST), oil spread method (OSM), blue agar plate (BAP), hydrocarbon overlaid agar (HOA) plate, emulsification index (EI), emulsification assay (EA) were assessed for their efficiency to detect biosurfactant producing marine bacteria. Forty-five strains of bacteria, comprising 18 Acinetobac...

As a bioaerosol sampling standard, Andersen type impactor is widely used since its invention in 1950s, including the investigation of the anthrax attacks in the United States in 2001. However, its related problems such as impaction and desiccation stress as well as particle bounce have not been solved. Here, we improved its biological collection efficiencies by plating a mineral oil layer (100 ...

We describe a high fidelity simulation method for estimating the sky coverage of multiconjugate adaptive optics systems; this method is based upon the split tomography control architecture, and employs an AO simulation postprocessing technique to evaluate system performance with hundreds of randomly generated natural guide star (NGS) asterisms. A novel technique to model the impact of quadratic...

Petri dishes (9 cm diameter) with one sheet of Þ lter paper inside of the same size were used for the experiment. Five different concentrations of neem oil, 100, 80, 60, 40 and 20% were used for the study. One milliliter (100%), 0.8 ml (80%), 0.6 ml (60%), 0.4 ml (40%) and 0.2 ml (20%) of neem oil were evenly soaked (spread with a spatula) on different filter papers of each Petri dish. Distille...

A new smoothing method is proposed which can be viewed as a finite element thin plate spline. This approach combines the favourable properties of finite element surface fitting with the ones of thin plate splines. The method is based on first order techniques similar to mixed finite element techniques for the biharmonic equation. The existence of a solution to our smoothing problem is demonstra...

Concentrat ion polarisation, decreasing the efficiency in membrane separation processes, can be reduced by increasing mass t ransfer between membrane surface and bulk of the feed stream. Analogous to techniques used in plate heat exchangers efforts have been made to enhance mass t ransfer in a plate hyperfiltration module by using a corrugated membrane in stead of a flat one. The corrugations a...

Introduction Professor Emil Huschke (1797-1858), a German anatomist first described the probability of deficiency in the development of tympanic plate of temporal bone, which was named as “Foramen of Huschke” or foramen tympanicum, which usually to get apposed in adulthood [1, 2]. It, if persistent in adult life, may result in complications like herniation of temporomandibular joint (TMJ), form...
