Being simple and cost-effective, small wind turbines are mainly used as energy option for decentralized rural electrification in developing countries. Since installation site of small wind turbine is normally decided based on the areas where electrification is needed rather than where there is best wind resource, low wind speed sites can not be avoided. However, under low wind speed conditions, energy output has been found to be lower than one which can be predicted. Many researchers have attempted to identify the reasons for such low performance and suggest requisite improvement. Poor starting behavior has been found to be one of the major drawbacks of which there had been many attempts to improve it. Never the less, still commercial small wind turbines depict low performance in low speed wind regimes. In this paper, the rotor parameters responsible for enhancing turbine starting were analyzed and the results used in innovative processes to come up with the rotor having high starting torque and high maximum power performance. Unlike conventional rotor of the horizontal axis wind turbine, the rotor comprises of extra shorter blades mounted on same hub circumference. Blade Element Momentum theory was used to predict the power performance of the novelty rotor.

The Civil Liability for Nuclear Damage Act, 2010 follows global practice in the field of nuclear civil liability and has a specific provision that enables a nuclear operator to exercise right of recourse against a supplier. The Civil Liability for Nuclear Damage Rules, 2011 provides explanation regarding the provisions enshrined in the Act. The Rules explains about the Supplier which has been formulated based on the industry practices of nuclear sector. The paper analyses the Civil Liability for Nuclear Damage Act and Rules on the issue of compatibility of right of recourse with the international nuclear civil liability principles and conventions, particularly with the Convention on Supplementary Compensation for Nuclear Damage, 1997. This paper also discusses the issue of right of recourse by nuclear operator against the supplier in the light of explanation about a supplier as provided under the Act and Rules.

The aim of this work was to analyze inlet effect and patterns development length of the vertical gas-liquid flow experimentally. The study was conducted in multiphase rig with a test section of 18m long pipeline and 60 mm internal diameter. Two types of inlets were considered. Four conductivity probe rings were installed at four different positions along the test section. Water flow rate was kept at 0.07 m/s by adjusting pump frequencies and water inlet valve. Air was varied from 4 m/s to 22 m/s at atmospheric pressure and temperature so that to attain different types of flow pattern. Recognition of flow patterns was done by considering four methods; observation with aid of high-speed camera, time series of conductance signals, signals probability density functions and distribution moments about mean. Conductance signals were collected for about two minutes for each test after attaining steady state flow. The results show that with steady state flow, patterns transition can occur within a test section while the inlet effect is very small for slug propagation within a test section.

This research was performed in order to allow the study of the chemical composition influence of the coking process load on the efficiency and the quality of coke. For this reason, the coking of the following loads was realized: Atmospheric residue (RAT), vacuum Residue (RSV) and catalytic Residue of cracking (RCC). (The residues are obtained from an Algerian crude oil).As the oil residues are rich for their strongly polar composition, such as the asphaltene resins, and complex structures units (SCU), which has a role in the formation of coke, and as the dispersion of these latter improves the quality of coke, a study on the stability of aggregation was carried out by the addition of one stabilizer (oil Extract) in the coking process load. The Compounding (Extracted from /RCC oil) has been drived to the best efficiency of coke. The study consists of the influence, this is characterized by the analyses Infra-red (IR) and x-ray diffraction (XRD).
