The intention of the study was to investigate effect physical conditions such as aeration rate (1, 3, 5 L/min) well chemical including sodium nitrite (NaNO2), urea (CH4N2O) and ammonium chloride (NH4Cl) on biomass productivity fucoxanthin concentration A. capitellata. optimum cultures were cultivated in f/2 medium using nitrate (NaNO3) at light intensity 100 µmol photons/ m2s with 2 L/min L bub...

Abstract The effect a transient heat flux has on in-tube boiling not been studied extensively for some refrigerants commonly proposed use in concentrated solar power organic Rankine cycle systems. In this study, the of abrupt step changes (upwards and downwards) inlet vapour quality to flow-boiling test section transfer coefficient was considered. Tests were conducted with R-245fa at saturation...

Thermal properties are necessary for the design and control of processes and storage facilities of food materials. This study proposes the measurement of thermal properties using easily constructed probes with specific heat capacity calculated, as opposed to the use of Differential Scanning Calorimeter (DSC) or other. These probes were constructed and used to measure thermal properties of white...

The slow regression rate induced by the high pyrolysis difficulty has limited application and development of hydroxyl-terminated polybutadiene (HTPB)-based fuels in hybrid rocket propulsion. Nickel oxide (NiO) shows possibility increasing HTPB-based catalyzing process polymer matrix our previous investigation; hence, this paper studies NiO particles thermal decomposition combustion HTPB fuel gr...

For a measuring instrument, a usual way to find the probability distribution of its measurement errors is to compare its results with the results of measuring the same quantity with a much more accurate instrument. But what if we are interested in estimating the measurement accuracy of a state-of-the-art measuring instrument, for which no more accurate instrument is possible? In this paper, we ...

The phenomenon of steam–water direct contact condensation has significance in a wide range industrial applications. Superheated steam was injected upward into cylindrical water vessel. Visual observations were conducted on turbulent jet to determine the dimensionless length compared nozzle exit diameter and maximum swelling ratio as function mass flux at exit, with gas ranging from 295–883 kg/m...

Flow boiling in microchannels is one of the most desirable cooling solutions for high power electronics. However, it challenging to promote flow performance, particularly critical heat flux (CHF), due their unfavorable liquid rewetting. Inlet restrictors (IRs) have been successfully used manage two-phase instabilities microchannels. IRs would result extremely pressure drop. In this study, witho...

Memory deficits and other cognitive symptoms frequently associated with mTBI are commonly thought to resolve within 7-10 days. This generalization is based principally on observations made in individuals who are in the unstressed environmental conditions typical of a clinic and so does not consider the impact of physiologic, environmental, or psychological stress. Normobaric hypoxic stress can ...

We describe general web-based photo management solutions. We will see how thesesolutions provide users with search and browsing functionalities but little more than this. We will then describe systems that take photo management to a further step and provide users with additional information. The systems that we first describe are contextbased services that provide users with some information. T...
