In thermoelectric coolers (TECs) applied external voltage potential is generated to a temperature difference based on the Peltier effect. Main and basic structure of TECs is in the form of single stage device. Due to the low efficiency, especially low coefficient of performance (COP) of thermoelectric coolers, optimal design of geometrical parameters of such devices is vital. For this purpose, ...

This paper discusses the performance of a novel Coral Reefs Optimization – Extreme Learning Machine (CRO–ELM) algorithm in a real problem of global solar radiation prediction. The work considers different meteorological data from the radiometric station at Murcia (southern Spain), both from measurements, radiosondes and meteorological models, and fully describes the hybrid CRO–ELM to solve the ...

s: Chromium is one of the unessential heavy metal that makes high toxicity in the plants. The aim of this study was assaying the changes that come from toxicity of (Cr ) on some biochemical, physiological and 6+ ionic specification of Brassica napus variety sari flower. The tests were conducted at hydro ionic conditions and at 0, 25, 50, 75 and 100 μm concentration of K CrO with four repeats in...

In this paper, we give the correlation and difference between M-convex fuzzy process and SLW-convex fuzzy process, and present some basic properties of these convex fuzzy processes, which improve some known results about the connection between those convex fuzzy processes and their graphs. In addition, we introduce a new notion of s-convex fuzzy process as a generalization of M-convex fuzzy pro...

Po l i t ical changes in Cro a t ia and Serbia and within B o s n ia away from the na t io nalist fo rces that ma de war in the 1990s ma ke it possible for the int e r na t io nal community to move mo re aggressively to break fina nc ial and military ties between Belgra de and Bosnian Serb na t io na l i s t s, just as the link between Za g reb and Bosnia...

X-ray fluorescence analysis using Cr K(alpha) spectra was applied to the determination of the mixing ratio of Cr(6+) to (Cr(6+) + Cr(3+)) in several mixtures of K(2)CrO(4) and Cr(2)O(3). Because the powder of K(2)CrO(4) contained large particles that were more than 50 microm in diameter, it was ground between a pestle and a mortar for about 8 h. The coarse particles still remaining were removed...

Knowledge of the three-dimensional structures of the lambda-Cro and lambda-repressor proteins in complex with DNA has made it possible to evaluate how these proteins discriminate between different operators in phage lambda. As anticipated in previous studies, the helix-turn-helix units of the respective proteins bind in very different alignments. In Cro the recognition helices are 29 A apart an...

Epitaxial CrO 2 thin films deposited on HF-cleaned TiO 2 (100) substrates exhibit very strong strain anisotropy, while those grown without the HF treatment step are essentially strain-free and display bulk-like magnetic properties. The HF treatment enhances the surface smoothness of the TiO 2 (100) substrate thus leading to the growth of epitaxially strained CrO 2 films. The magnetic easy axis ...

The reduction kinetics of Fe(III)citrate, Fe(III)NTA, Co(III)EDTA-, U(VI)O(2) (2+), Cr(VI)O(4) (2-), and Tc(VII)O(4) (-) were studied in cultures of dissimilatory metal reducing bacteria (DMRB): Shewanella alga strain BrY, Shewanella putrefaciens strain CN32, Shewanella oneidensis strain MR-1, and Geobacter metallireducens strain GS-15. Reduction rates were metal specific with the following rat...
