THE STRESS DETERMINATION FOR WATER
INTAKES WITH PIPES INSIDE PILES
This paper presents the initial stress calculations performed in order to validate a future innovative solution which incorporates both the sluices and the water intake with the supply pipes embedded within the concrete piles.
A brief calculus was done to estimate the supplementary forces involved in the dam stress. It starts from simplifying assumptions in order to estimate the stress supported by the concrete piles. The obtained results will be furthermore used to determine if the envisaged solution requires special methods of foundation or structural reinforcement.

THEORETICAL ASPECTS REGARDING THE STRENGTH CALCULATION AND THE DEFORMATIONS OF THE HORIZONTAL TURBINE RUNNER CHAMBERS
This paper presents main theoretical considerations regarding the strength calculation and the deformations of the horizontal axial turbine runner chambers – upstream bulb. The most suitable functional and constructive solutions – for those bulb turbines which designed at Hydro-Engineering, the runner chamber has the lower half embedded in the concrete, and the upper half of this is fixed through a bolted threaded connection and threaded studs. The strength calculation of the deformations is made only for the upper half of the runner chamber.
The establishment of the fundamental equations regarding the strength and deformation calculations have been made taking into account the theory of the plane and curved plates of S. Timoshenko. For solving the equations and avoiding the in determinations it has been used the energetic method (Castigliano’s method). Considering the stressing types that are applied to the upper half of the runner chamber in the paper, it is shown the forces and moments that is stressing the threaded connection of the upper half in relation to the lower half which embedded in the concrete

STUDY OF THE EFFECT OF THE FAST FRANCIS TURBINE BLADES’ SPIN AROUND AN AXIS, FOLLOWING CFD ANALYSIS OF FLOW AND RESULTS OF MEASUREMENTS IN THE LAB
The present paper propose an analysis of the rotation around an axis effect of the runner blades that compound the fast Francis turbines in order to increase their energo-cavitational performances. First step was done after the analysis of the runner which resulted from the calculations and hydro-dynamic design. This analysis was performed both theoretically using the finite element software package called CFX Blade Gen, and through experiment within the Test Laboratory for Hydraulic Turbines from Hydro-Engineering. Second step of the research consisted in rotating the blade around the axis with a certain angle in order to increase the absorbed flow, holding the rim and the ring from the initial blade. Rotating was performed in different angles by making the finite element analysis for all the rotating angles. In order to improve the cavitational component it was proposed and realized an extension of the blade with an appropriate covering degree, without any visible effect over the energetic features, these being maintained within the permitted error range that admitted by the IEC 60193 code.

A MATHEMATICAL APPROACH TO THE LOSSES OF TRANSMISSION LINE UNDER NON-SINUSOIDAL REGIME
In this paper we present a mathematical proof of additional losses in the electrical energy transmission line due to superior harmonics. The proof is based on the Cauchy – Buniakovski – Schwarz inequality, a very important inequality in mathematics. Was considered a simplified model, but the obtained result generalizes to complex electrical circuits. At the beginning of the paper there was a more general overwiev of the issue of technological losses in power transmission line. Finally, we draw the conclusions and we indicate the references.

On 1 September 2010, Gaddafi opened and put into operation the total, BIGGEST BUS aquatic ever built on Earth, being called „the 8th wonder of the world”! A network of pipes 4 m in diameter, buried in the ground to prevent evaporation, carrying more than 5 million m3/day from a reservoir underground aquifer discovered in the desert, to areas populated coastal cam Nile flow as 200 years. The project cost was estimated la25 billion dollars, and Libya did not borrow a cent ANY IMF, World Bank etc. The project was conducted by experts from South Korea, but all equipment, piping, were built in Libya. The price of water brought from the Sahara is 35 cents/m3 to $ 3.75/m3 would have cost as desalinated seawater, and e … incomparably better. Now that Libya has land (now) fertile water, but little population, Egyptian farmers invited to come and work there Libya earth. An impressive project by Libya without indebtedness and ask for help from the West and that just as the same financial groups „developed countries”, encouraging the construction of a seawater desalination plants, water rationing in NOM (New World Order).

Această intrare a fost publicată în 2015 Volumul 27 la de

O uzină mamut în jurul căreia s-a construit un oraș. În epoca de glorie era al doilea producător de tractoare din lume. Până în 1989 a adus venituri de 500 de milioane de euro, bani cu care s-au plătit datoriile țării. Uzina avea 26.000 de angajați. După 1989, guvernele au avut interesul ca Tractorul să nu dispară pe durata propriului mandat. Rețeta a fost aceeași – s-au șters datorii, s-au acordat credite și s-au elaborat programe, fabrica fiind ținută în viață în mod artificial. Pentru voturi, pentru o guvernare liniștită.
