In the present study we investigate the relationship among HSSW and SSSW with interplanetary parameters Dst and proton flow pressure for the time interval 2005 -2009. The present study investigates by means of stastical method employed for average values. The solar wind is classified into two categories- • High speed solar winds (HSSW) which have value > 450. • Slow speed solar winds (SSSW) which have value < 450. We got the emergence of charged particles from sun varies and the variation causes change in various solar activities.

In this paper Fuzzy Logic and proposed Neural Network based Direct Torque Control of Induction motor are designed. A Back Propagation Neural Network is used in proposed method. The training patterns of Neural Network are extracted from Fuzzy Logic Controller based Direct Torque Control of Induction Motor. The operating characteristics of the proposed drive is compared with the Direct Torque Control and Fuzzy Logic Control to verify the effectiveness under various conditions by investigating the transient response for the step change of speed command and the load torque.

After strenuous exercise performed by the Brazilian military, there was a moderate increase in oxidative stress confirmed by the increment in TBARS, so the health risk should have been minimal. The basic blood count showed values considered healthy indicating a rigorous homeostatic control of the hematological parameters for this type of exercise. The remaining parameters suffered significant alterations: decrease in sodium, increase in potassium, decrease in chlorine, decrease in magnesium and increase in copper.

In South America, water in several regions is a strong limiting condition for socioeconomic development. More constant losses are observed in social and economic areas due to drought, for example, in the Northeast of Brazil (NEB) and Central West of Brazil (CWB), mainly in activities such as agriculture, animal husbandry, electricity distribution, water supply and tourism.

In the purpose of good recording and data reporting for all the necessary actions with radioactive waste saved and proceeds by the radioactive waste treatment and management directorate (RWTMD); database builds. The database is covering the processing steps of radioactive waste started with a reception and identification ending with disposing of management data per each package (container).

This work focused on the determination of the accumulator potential of five local plant species for use in phytoremediation. In plants, trace elements such as Zn, Fe, Cu, Co, Mn, Mo and Ni are necessary for biological processes, but their excessive accumulation can be toxic. Other non-essential elements, such as Cd and Pb, can also be absorbed by plants, thus constituting a potential hazard since they enter the food chain. Phytoremediation is the use of plants and their associated microbes to clean up the environment.

The aim of this paper is to present a viable and realistic approach for management of E waste in India by integrating the formal and informal sector involved in its handling and processing. Along with that, pragmatic ways to implement EPR (extended producers responsibility) using the concept of joint collection system and partial recovery facility, making it far reaching are suggested with a view to make it a driving factor in formalizing the informal sector.

The educational accountability includes improving both educational quality and educational equity. Accountability is a political and legal concept that denotes the responsibility of an organization or individual (an agent) to perform within the specified boundaries set by some higher political authority and to report to and to justify one’s actions to this authority. Accountability is a basic tenet of democratic political systems (Mathison, 2009; Ryan and Feller, 2009).

This research investigates the effects of thermal annealing on the optical, morphological and structural properties of Tio2 thin film. Tio2 was deposited on glass substrate by spin –coating technique using spin –coater model laurel WS-650Hz-23NPP. Surface morphology of thin film was studied using Scanning Electron Microscope (SEM) model ASPEX 3020. The optical absorbance and transmittance measurements were recorded by using a single beam spectrophotometer Avantes model Avalight-DH-5-BAL.

Aim: To determine if early laparoscopic cholecystectomy (LC) or delayed laparoscopic cholecystectomy (LC) is gold standard in our experience in Acute Cholecystitis. Methodology: The study was conducted in Department of General Surgery in Vinayaka Missions Karaikal under same surgical team.We compared surgical difficulties, clinical courses and complications between 20 patients undergoing delayed LC and 25 undergoing early LC.
