To speed up the process of detection of tamper in an image it is withheld to segment the image, embed segment with watermark and key as to trace the tamper segment in which key is not found rather than tracing for entire image for tamper detection. Tamper detection algorithm based on superpixel segment level key encryption with svd based watermarking scheme is proposed. This method finds tamper location from watermarked superpixel segments of watermarked image. Secrete key embedded in each segment of watermarked image for finding tamper segment first. If keys not found from any of the segment that segment shows tamper segment of image then find area which is tampered from that segment. To improve the efficiency of the proposed tamper detection against various security attacks such as collage attacks, VQ attacks and content removal attacks. The experimental results shown that proposed tamper detection scheme is shows better performance in terms of efficiency of tamper detection rate higher than 99% in average complex attacks, 100% in common attack and tamper finding speed is 0.02 to 0.04 sec. in various attacks.

Education has the key role in human capital formation. It empowers the society by increasing awareness, skills, efficiency and productivity, but does it empowers the people who educate the society? This paper scrutinizes the impact of different education levels on teacher’s earnings of public sector educational institutes in Pakistan. By employing Mincerian Human Capital model. A sample of 150 teachers is used for the analysis. Data is collected through field survey and questioner about educational level and experience from public sector teaching staff of Quetta city and OLS Regression method is used to determine the impact of Education and experience on earning. According to our results, completed years of education and years of experience have positive significant impact on monthly income. But years of experience increases income at a decreasing rate.

This paper focuses on the structure of corporate leadership and how it can help achieve Early Childhood Education (ECE) goals in protecting the rights of children. It establishes that corporate leadership has not fully been exercised and implemented in Early Childhood Development (ECD) centres, and this is due to the administrator’s inability to steer stable and sustainable centres for protection of rights of children and unprofessional management. The study employed descriptive surveys, and stratified sampling was used to obtain a sample of 52ECD centres in Baringo County, Kenya and the target population involved the staff in ECD centres. This paper establishes that corporate leadership is vital towards accomplishment of protecting rights of children and that curriculum supervision plays a major role in quality education and protecting children rights. Therefore it recommends a full review of implementation of corporate leadership in ECD centres and training of staff to achieve this course

The Erbium doped KDP crystals were grown by Sankaranarayanan-Ramasamy (SR) method with the vision to improve the properties of the crystal. The chemical composition of the grown crystals is confirmed by EDAX Analysis. The grown crystal was characterized by PXRD and UV-Vis analysis. The SHG efficiency is determined by Kurtz powder technique. The dielectric constant, dielectric loss and ac conductivity of the crystal were studied. The functional groups are identified by FT-Raman analysis. The Optical transmission and SHG studies shows the suitability of the ingot for optical applications.

Rice bran, one of the most abundant and valuable byproducts produced during the rice milling process, is of steadily growing interest in recent years due to its potential health benefits. Herein, we investigate and report the physicochemical properties of rice bran obtained from Mubi, Adamawa State, Nigeria. The rice bran was initially combusted and soil samples of the baked, unbaked soil and surrounding particular area where we carried out the combustion were collected and analyzed for its physicochemical properties. The results revealed that the baked soil has a higher concentration of calcium, magnesium, potassium and sodium than the unbaked soil. Furthermore, retention of water (tension) and the ability to absorb water (infiltration) was discovered to be higher in the baked soil sample. This shows that the heat of combustion of rice bran affects the physical, chemical and mechanical properties of soil in a peculiar way.

Green house experiment was conducted to explore the influence of different concentrations of Vermicompost in root–knot nematode management against Meloidogyne incognita infecting Cluster bean Cyamposis tetragonaloba. Vermicompost fortification treatment resulted in reduced nematode infection and increased growth characteristics such as shoot – root length and shoot – root weight. With the increase of concentration of Vermicompost corresponding increase noticed in growth characteristics of treated plants. Vermicompost fortified plants showed increment in sugar, protein and lipid over untreated control. Increment of these metabolites reflects treated plants were metabolically cope up the infection and promoting excessive plant growth.In vitro studies of hatching trials revealed significant reduction in larval emergence. The percent reduction of larval emergence showed a significant positive correlation with increased concentration of Vermicompost. Vermicompost treatment significantly affects the soil population of nematode which again reflects a dosage dependent phenomenon. Present investigation confirms Vermicompost as an excellent growth promoters and potential prophylactic agent.

Geophysical methods widely used in oil and gas exploration. Modeling of gravity data is used extensively to illustrate the geometry and interface between the sediments and bedrock. Which can help the salt dome, anticline folds, dome-shaped uplift of the continental platform and reef masses to be identified. There are various methods to illustrate the bedrock topography, and we will describe one of these methods in present paper. Using the upward continuation, we extract the residual gravity anomaly which in fact shows the local effect of bedrock gravity on the observed gravity. Then, according to the Oldenburg – Parker method, the residual gravity data are inversed and finally the 3D geometry the bedrock is illustrated. It should be noted that some software’s like Surfer and Excel are used in this research but the program main code is written using Matlab programming.

The first stage of the study consists of defining rock types by relating Geological framework, lithofacies, petrology to porosity, permeability, and Water saturation. Rock types represent reservoir units with a distinct porosity -permeability relationship and a unique water saturation range for a given height above the free water level. We also describe the conventional methodology used to evaluate water saturation from sections of the electric log of a well. The second stage of the work involved the analysis of the cored samples of the well (SANDS D 2, E1-8).Which will lead to the determination of the water saturation of the well. The third stage of the work dealt with the integration of the core analysis result with formation evaluation data to define reservoir water saturation. By using a proposed water saturation model, known as the molco water saturation model. It was observed that the conventional Archie water saturation gave the water saturation for the well section as 74.26% while the model gave it as 41.6%, giving a consolidated difference of 33.20%. This result will contribute to the understanding of tight reservoirs and making an impact on reservoir development.

A study was conducted to study the effect of integration of nitrogen sources on okra (Abelmoschus esculentus) grown in sandy regosols. Nitrogen sources farmyard manure, poultry manure, Amutha Karaisal and urea were applied on equal N basis at 135 kg Nha-1. Organic nitrogen (N) sources were used solely and in combination with urea at 50% N from each. And P2O5 and K2O were applied at the rate of 90 kg ha-1 by triple super phosphate and muriate of potash respectively. There were eight treatments replicated thrice. Among the treatments, yield was superior in 100% N supplied by poultry manure and next was followed by 50% N from farmyard manure + 50% N from Urea. The influence of AmuthaKaraisal was inferior in yield than other manures. There was no significant difference in average length of pod, but there was significant difference in average number and fresh weight of pod.
