Electrical power cables in tidal turbine farms contribute a significant share to capital expenditure(CAPEX). As a result, the routing of electrical power cables connecting turbines to cable collector hubs must be designed so as to obtain the least cost *** is referred to as a tidal cable routing problem. This problem possesses several variants depending on the number of cable collector hubs. In this paper, these variants are modeled by employing the approach of the single depot multiple traveling salesman problem(mTSP) and the multiple depot mTSP of operational research for the single and multiple cable collector variants, respectively. The developed optimization models are computationally implemented using MATLAB. In the triple cable collector cable hub variant, an optimal solution is obtained, while good-quality suboptimal solutions are obtained in the double and single cable collector hub variants. In practice,multiple cable collector hubs are expected to be employed as the multiple-hub configurations tend to be more economic than the single-hub *** has been confirmed by this paper for an optimal tidal turbine layout obtained with OpenTidalFarm. Suggestions are presented for future research studies comprising a number of heuristics.

作者： Derbyshire, Edward de Mulder, eduardo Nield, Ted

The International Year of Planet Earth＇s triennial programme was launched is some style, and on three continents, in January 2007. Geoscientists from ＂the round Earth＇s imagined comers＂ gathered for the inaugural meeting of the Board of the International Year of Planet Earth （IYPE） Corporation on 9 and 10 January 2007. The 15 Board Members （Figure 1） were joined by IYPE National Committee representatives, International and Associate Partners, observers and by Professor Aubrey Manning, a Goodwill Ambassador of the IYPE.

The pressure versus temperature phase diagram of a shoulder-like potential is exactly computed in one system of particles interacting through a multiscale dimension. The N-shoulder potential exhibits N density anomaly regions in the phase diagram if the length scales can be connected by a convex curve The result is analyzed in terms of the convexity of the Gibbs free energy.

Zeta potential measurement on lithium lanthanum titanate nanoceramics

The zeta potential, isoelectric point, and agglomeration of ***3 （LLTO） nanoparticles dispersed in aqueous media at different ionic strengths have been studied. The zeta potential was determined from electrophoretic mobility measurements, according to Smoluchowski＇s equation, for Li0.5La0.5TiO3 suspen- sions in NaCl and KCI electrolytes with ionic strengths of 1, 10, and 100 mmol/dm3. The isoelectric point （IEP）, zeta potential （ζ）, and the agglomeration were shown to strongly depend on the ionic strength of the Li0.5La0.5TiO3 aqueous colloidal suspension in both NaCI and KCI electrolytes, which allows the deter- mination of the effects of environmental conditions for ***3 manipulation in aqueous colloidal systems. The suspensions of Li0.5La0.5TiO3 nanoparticles reach the IEP in the pH range 0f3-5. The （ of Li0.5La0.5TiO3 nanoparticles varied from positive to negative values with a pH increase, which allows for the control of the surface charge depending on the purpose. The pH range of 7-g and an ionic strength ≤1 mmol/dm3 are recommended as the most suitable conditions for both the LLTO colloidal shaping techniques application and the LLTO-based nanocomposite formation.

Small bowel obstructions （SBOs） are primarily caused by adhesions, hernias, neoplasms, or inflammatory strictures. Intraluminal strictures are an uncommon cause of SBO. This report describes our findings in a unique case of sequential, stenotic intraluminal strictures of the small intestine, discusses the differential diagnosis of intraluminal intestinal strictures, and reviews the literature regarding intraluminal pathology.
