In this paper the modeling and analysis of suitable locationand size of capacitor banks installed at 11 kV bus of 132 kV grid station have been carried out with an objective of improving the voltage profile and power loss reduction. At present capacitor bank of full size, i-e 1.21 Mvar is installed at 11 kV bus at grid station. The aim of this paper is to present small sized capacitor banks that would be installed at different feeders instead of one large size capacitor bank at 11 kV bus.

Callus induction was tried with stem explants (nodal region from third node from top of canopy) harvested on 30 days after seed germination from in situ control and supplementary ultraviolet-B irradiated (UV-B = 2 hours daily @ 12.2 kJ m-2 d -1 ; ambient = 10 kJ m-2 d -1 ) three varieties of black gram viz. VAMBAN-3, NIRMAL-7 and T-9 to assess their viability for germplasm storage. Callus induction failed to occur in control and UV-B exposed VAMBAN-3, NIRMAL-7 and T-9 stem explants. However, stem explants from unstressed NIRMAL-7 proliferated axillary bud.

As a part of the systematic study of heavy metals phytoremediation, hydroponically grown Indian mustard (Brassica juncea) seedlings were selected as model eukaryotic plant system for the characterization of Zn and Cd induced tolerance in phytoindicators. 10 cultivars of Indian mustard (Brassica juncea) were grown on MS media with varying levels of Zn and Cd separately as well as in combinations. 6 days old seedlings were harvested and dissected into different organs. Each organ was further analysed for its proline content.

Background and Aim: Doppler ultrasonography of hepatic vasculature might indirectly reflect histological alteration, namely liver fibrosis. This study aimed to assess different Doppler parameters which might non-invasively predict the stage of liver fibrosis. Methods: 55 patients with HCV related chronic liver disease were included. They were divided into: Group I: 32 patients with chronic hepatitis C without cirrhosis and Group II: 23 patients with cirrhosis (Child A).

Forest resources have historically played a significant role in the economy of the Uttarakhand since ancient times.

The present study deal with wastewater treatment by four selective filtrations (Sand Filter, Sawdust Filter, Coal Filter, Ceratophyllun demersum l. Filter ) to reduce some physical ,chemical and bacteriological properties of wastewater such as (TS, COD, BOD, pH ,EC,TN, TP, Cd, Cu, Ni, Pb, Zn Fecal coli bacteria) . Samples collected from wastewater treatment station near Al-Nassyria city center - south Iraq .The result showed that selective filtrations specialized Sand Filter reduced these properties above and decrease of pollutant in this study.

Livelihood security has remained pervasive in most disaster areas irrespective of the interventions by governments as well as local and international development bodies. The inability to isolate distinct determinants of livelihood security may lead to interventions and solutions that may further increase, rather than mitigate livelihood insecurity. This study sorts out to identify determinants of livelihood security in the Lake Nyos area.

Background; Hearing loss during chemo radiotherapy is a common problem encountered during the treatment of head and neck cancers.

The purpose of this paper is to define and study the notion of nano g*p-closed sets and nano g*p- open sets in nano topological spaces. Also to investigate nano g*p-interior and nano g*p-closure.

An acute shortage of river sand which is generally used as a fine aggregate in concrete has been affecting the construction sector. The scarcity has led to the skyrocketing price of sand, escalating construction costs. The situation has dashed the dreams of many in the lower- and middle-income groups to own a house. There were studies about the depletion of river sand and the need for scientific management and exploitation of the available resource.
