A regional geoelectrical study was embarked upon covering some major towns within the Niger Delta and Anambra basin. Some of the towns include; Owerri, Umuahia, Ohafia, Aba, Umuosu, Ngwa, Mbaise, Okigwe, Lekwesi, etc. About 100 Vertical Electrical Sounding points were established along two long profiles running perpendicularly to each other at North-South and East-West directions covering a distance of about 110km in each traverse. The maximum electrode spread was 500metres, AB/2. The schlumberger array was adopted on the field. The ABEM Terrameter SAS 4000 was used for the data acquisition. The purpose of the study is to examine the variability in lithological units both vertically and horizontally from the North to South and East to West along these profiles because there have been reported cases about land degradation like; gully erosion, landslide, minor subsidence, road failure, etc within the study area. The field data were processed with computer softwares. Iso-resistivity values at AB/2 equals 1m, 4m, 8m, 15m, 50m, 150m, 250m and 350m at surface electrode spacings were plotted and processed for each VES point in order to reveal the variation in resistivity with depth and variability changes in lithological units with depth. This procedure was repeated for all the VES stations on the East-West profile and North-South profile. Results show that the top soil contour has resistivities between 200?m and 9000?m while at AB/2 = 4m, resistivities are 500 - 1000?m (Aba), 1000 - 5000?m (Owerri), 2000 - 2500?m (Afikpo). Results were also obtained for AB/2 = 8m, 15m, 50m up to 250m. These resistivity values were interpreted as clay, shale, sand, etc, accordingly. From the correlation of the VES points, other geologic structures like faults, boundaries, flood plains, landsides are identified. Other environmental implications are highlighted.

Radio Frequency Identification is the hardware concept to provide small RFID tags to the user with the electromagnetic waves and produce the signals to it and then access the data. In this project we have implemented the concept of Networking using java and the web application. The project aims at making the document verification and accessing very easy and saving a lot of time and energy and commotion among users.

To assess the relationship between placental location and development of Preeclampsia and its maternal and perinatal outcome. Methods: Patients attending antenatal clinic at second trimester in the Dept of OBG in Dr. B R Ambedkar Medical College and Hospital during June 2014 to December 2014.It is a prospective study. Result: Out of 100 patients in the study, 61(61%) patients developed Preeclampsia. Conclusion: This study indicate that presence of lateral placenta strongly suggest preeclampsia and also shows that lateral placenta have high uterine artery resistance, so can be considered as screening method also.

The case of prohibition of transaction for real or legal persons is a common case in notary public’s offices. Notary public’s offices avoid doing their routine duties in creating documents when they encounter personal names that their legal actions are banned by judicial authorities and related circulars have been announced. Studying the legal basis of individuals’ transaction restrictions, the limitation of basic conditions of transaction correctness, the position of legislator’s Injunctions to stop transactions and similar issues, bring this point to mind that doing transactions and transferring properties in these situations is correct, and such injunctions cannot form a reason to nullify the transaction.

Accurate estimation of water and soil losses from agro-ecologically diverse areas is extremely important for designing appropriate resource management or soil/ water conservation measures. The developed KW-GIUH-MUSLE(Kinematic wave-Geomorphlogical Instantaneous Unit Hydrograph-Modified universal Soil loss equation) model is tested for its sediment yield estimation potential on three agro-ecologically diverse micro-watersheds in Almora district of Uttranchal. It is observed that estimates are associated with about 49% mean relative errors and mean DV value of about 0.51 in Salla Rautella and Naula micro-watersheds. This showed that point predictions of annual sediment yields are of moderate quality. However, root mean square error estimates and comparison of mean and standard deviation values for the observed and simulated sediment yields showed that long term sediment yields could be estimated quite realistically. This is also observed in Deolikhan micro-watershed that storm wise sediment yield estimates are associated with about 6% mean relative error and 0.94 mean DV value. The analysis thus clearly showed that the developed KW-GIUH-MUSLE model could indeed be utilized for obtaining reasonable sediment yield estimates for un-gauged/ inadequately gauged micro-watersheds.

Short term load forecasting is very essential for daily planning in an electrical system. Power demand for the next few hours or days need to be predicted for smooth and economical running of a power system. Prior data is essential to make the prediction. There are different methods to do the forecasting or prediction based on previous data. This paper analyses the time series method of forecasting.

This study examines the relationship between socio economic and demographic factors on the child health status by employing Logistic Regression Model. For this the data from the Pakistan Demographic and Health Survey (PDHS) 2006-07 was utilized. Education affects the capacity and the behaviors of the people living in the various regions along with some other explanatory variables. It was found that child’s health depends directly or indirectly on parental education and health acquiring activities. Parents with improved social status, protected source of water and access towards health services had better status of their child health. Death rate of child was found high among children of small aged mothers. Increase in birth space diminishes the chances of death and sickness of child. First order births faced great risk of death and sickness. Health care matter like maternal and fetal care in expecting period, delivery place and person who assisted during child birth also impact child physical condition. Research study suggested that Literacy rate should be enhanced to develop the understanding about reproductive health and to optimise the use of accessible health resources. Training and skills should provide to traditional birth attendants and enhance their contacts with professional health staff.

Oral drug delivery systems being the most economy and leads the worldwide drug delivery market. The major drawback in oral drug formulations is low and varying bioavailability, which mainly results from poor aqueous solubility. It is estimated that 40% of active substances are poorly water soluble. Among the various available approaches to improve the oral bioavailability of these molecules, the use of self-emulsified drug delivery systems (SEDDS) has been shown to be reasonably successful in improving the oral bioavailability. However, traditional preparations of SEDDS are usually prepared in the liquid state which produces some disadvantages, such as high production costs, low drug incompatibility and stability, drugs leakage and precipitation. To overcome this problem solid SEDDS (S-SEDDS), prepared by solidification of liquid/semisolid selfemulsifying (SE) ingredients into powders, have gained popularity. The S-SEDDS not only increase the solubility of the drug, but also exhibits the advantages of solid dosage form. The present review explains the recent trends in Solid SEDDS (S-SEDDS) with regard to the selection of lipid systems for current formulations, solidification techniques and the development of solid SE (self-emulsifying) dosage forms and their related problems and possible future research directions.

This paper presents an approach to the development of a speaker independent, continuous word Speech Recognition System for a large vocabulary. The feature extraction is based on Mel-scaled Frequency Cepstral Coefficients (MFCC) and template matching employs Dynamic Time Warping (DTW). In general, efficiency of the speech recognition system in noise free environment is impressive. But, in the presence of environmental noise the efficiency of the speech recognition system deteriorates drastically. As an attempt to overcome this drawback, Spectral Subtraction (SS) is used for de-noising the speech signal before feature extraction and Convolutional Noise Removal is performed after feature extraction.

Holigarna species are medicinal plants that widely used in India but the exactly active component and medicinal activity such as anticancer activity is not well known. In the present study total polyphenols, antioxidants, antimicrobial and anticancer activities of the water and methanolic bark extracts of Holigarna arnottiana and H. ferruginea were analysed by standard protocols. In methanol higher yield extract was obtained when compared to aqueous in both plant species. The antioxidant activity of the bark extracts of two species of Holigarna was found to be in the range of 685 to 1397 mM Fe (II)/g raw material in aqueous and methanolic extract. The results also proved that antioxidant activity is related to plant constituents including polyphenol content in the extract. The methanolic extract showed a good antibacterial activity compared to aqueous extract over Vibrio parahaemolyticus and Staphylococcus aureus, as these pathogens can be controlled using bark extract of both the plants. The methanolic bark extracts exhibited antifungal activity against tested both fungal pathogens.The cell lines treated with methanolic extract possessed higher percentage of cell viability compared to aqueous extracts in both the plant species. Up to 50µg/mL of methanolic bark extract, the viability is above 60% then it decreases and inhibition increases and thereby proved its anticancer activity.
