Visual Secret sharing (VSS) suffer from secret transmission risk as the shares in VSS appear as meaningful image or noise like image. In order to overcome such problem a new Natural image based Visual Secret Sharing (NVSS) scheme was presented. Using NVSS scheme one can distribute a secret image using n-1 natural images and one noise image. It does not modify the contents of natural images. The encryption phase extracts features of every natural image. The secret image is converted to a share by performing computations on secret image and feature extracted from natural images. On the other hand the secret image is retrieved by performing computations on the share and the feature extracted from natural images. This scheme can be used to decrease the risk of transmission and also resolve the management problems. In our proposed system steganography is included to NVSS scheme to securely transfer data by hiding it behind the secret image. To increase the security further this secret data is encrypted before performing steganography. Hence the secret data is in encrypted format. This secret image is then converted into share which is finally embedded in cover image. This proposed scheme is able to share black and white, grey level or color images secretly. Also this scheme is easy to implement.

An in vitro investigation was carried out to explore the production of cellulase and xylanase enzyme in the basidiocarp of Pleurotus spp .The result of the study revealed that exo ?-1,4 glucanase and ?-glucosidase activities were highly pronounced in Pleurotus ostreatus (0.87 and 1.29 Umg-1 enzyme protein) than Pleurotus cornucopiae (0.38 and 0.71 Umg-1enzyme protein). Endo ? 1,4, glucanase was expressed maximally (1.56 Umg-1 enzyme protein) in P.cornucopiae than in P.ostreatus (1.28 Umg-1 enzyme protein). Xylanase activity was registered at a higher level of 0.058 Umg-1 enzyme protein in P.ostreatus than in P.cornucopiae (0.037 I Umg-1 enzyme protein)

One of the major problems in using subsurface drain is pipe and envelope clogging by mineral materials. Such a process is the result of disturbances of soil structure during drain installation. Drain filter selection follows definite rules and neglecting them can result in project failure. Current study is based on evaluation of three kinds of synthetic filters in comparison with mineral filters. Two soil samples of northern Khorram Shahr (1.65m deep) were obtained for the study. Physical and chemical analysis on samples showed they do not have major differences in texture and particle size distribution (PSD). Original recommendations based on previous studies on synthetic filters in terms of PSD curve and soil texture was to use PP700 type. Two other types were also chosen as the upper and lower boundaries of the main choice. The performance of three types of filters (PP450, PP700 and PP900) was assessed in terms of clogging potential using ASTM-5101standard test. In addition, mineral blanket was designed according to the USBR criteria. Experiment was conducted in three treatments and completely on random. The test was conducted in laboratory, using physical model for infiltration (according to the ASTM D-5101 standard) and by creating four different hydraulic pressure head (25, 50, 75 and 100cm). In the study, changes in outflow from soil-geotextile system, hydraulic conductivity, gradient ratio and hydraulic conductivity ratio were analyzed for four filters. The results showed that 1) in terms of the gradient ratio, none of the filters were found sensitive to clogging, 2) outflow from mineral filter was 2 to 3 times greater than for geotextiles, 3) the hydraulic conductivity ratio of mineral filter for PP450, PP700 and PP900 geotextile filters were 3.47, 4.17 and 5.57 respectively, and 4) comparing outflow and hydraulic conductivity variations, geotextile filter of PP450 type was found the best. According to the optimization results, for PP450, optimum values for decision variables at different hydraulic heads (H) and drain outflows (Q) were equal to 47 cm and 0.166 cm3/s and for PP700 were 114 cm and 0.183 cm3/s. These values were equal to 94 cm and 0.198 cm3/s for model PP900 and 237 cm and 0.298 cm3/s for gravel filter, respectively.

In developing countries, 60% of project management professionals appear to lack knowledge that timely completion, budget fidelity, and high quality are critical success factors for completion of construction initiatives. The purpose of this correlational study was to examine the relationship between project budget and the independent variables of safety, environmental impact, and site disputes in the Greater Accra Region of Ghana, using the underpinning of the theories of accident causation, scientific management, and strategic management. One hundred and sixteen project managers, randomly selected from the population of construction professionals in the Greater Accra Region of Ghana, completed the survey entitled the Six Key Performance Indicators developed by Ngacho and Das (2014). The application of multiple linear regression for the analysis of data, indicated a weak positive correlation between the independent variables (safety, environmental impact, and site disputes) and project budget, F(1, 114) = 37.08, p < 0.001. Site dispute recorded the highest beta (? = .29) followed by environment (? = .22), quality (? = .06), and safety (? = .04). Attention to key performance indicators associated with dispute and environmental impact could improve project outcomes in the Ghanaian construction sector. The study findings could be useful to improve the quality of projects and may benefit the lives of professionals and community members in the area.

Extensive quantum chemical calculations of energy, geometrical structure, harmonic vibrational frequencies and the construction of theoretical spectrograms of IR and Raman spectra of the molecule, methyl 2,4-dihydroxy-6-methyl benzoate(methyl orsellinate) have been carried out by Hartree-Fock (HF) and Density Functional Theory (DFT/B3LYP) method with 6311++G(d, p) basis set. The assignments of normal modes of the vibration of the title molecule along with the observed frequencies (FT-IR and FT-R) and scaled frequencies have been obtained by HF/DFT computation. The simulated NMR spectra are obtained by (GIAO) gauge independent atomic orbital method and their chemical shifts are compared with the experimental 13C NMR and 1H NMR spectra. Molecular geometric parameters, dipole moment, mullikan charge, thermodynamic properties, FMO analysis and NLO properties have also been computed and discussed in a detailed manner.The electrostatic potential surface and the mullikan charge analysis indicates that the oxygen atoms of the molecule act as reactive centers for nucleophilic attack .The temperature dependence of the thermodynamic properties such as entropy (S), enthalpy (H) and heat capacity (Cp) from 50K to 700K were also determined.

In the present work experimental setup is planned, designed and fabricated for the study on jet impingement heat transfer on flat and curved surfaces of radius of curvature 0.5, 0.725, 1.3. Experiment was conducted for the varying Reynolds number of 3500, 5500 and 9000. The heat transfer characteristics of a slot jet obtained from nozzle designed is impinged on concave and flat surfaces with constant heat flux have been analyzed experimentally. The effects of surface curvature R/L, the dimensionless nozzle to surface distance and Reynolds number on average Nusselt number of plate is obtained. It is found that Reynolds number has greater influence on heat transfer from the plates as the H/W ratio varies. The findings of the present study can be utilized to investigate the curvature of the blade for which heat transfer is more and to optimize the cooling rates in the surfaces for the better design of the gas turbine blades.

This study examines the short and long run causal relationship between financial sector development and economic growth in Nigeria using the Autoregressive Distributed Lag (ARDL) approach to cointegration analysis, Vector Error Correction Model (VECM), on yearly data over the period 1981 to 2017. Two factors from Cobb Douglas production function (labor and capital), and oil prices are used including an index of financial intermediary development constructed from six indicators of financial intermediary development using principal component analysis. The results show that financial sector development index; both capital market and banking sector development are insignificant in influencing economic growth in Nigeria. In general, the results highlight the weakness of the Nigerian financial sector in stimulating economic growth through resource mobilisation and allocation and presents oil sector as the dominant factor driving economic activities in Nigeria. The study recommends the need to establish financial institutions that would strengthen and resolve the institutional and structural problems in the economy and create structures that would sustain other causal factors that mediates growth and financial intermediation where appropriate.

This phenomenon provides a nonlinear partial differential equation as a governing equation, which can be solved by Homotopy Perturbation Sumudu transform method (HPSTM). The numerical and graphical results are discussed using MATLAB.

Prime Minister Aziz has approved the export of an additional 500,000 tons of wheat this year in the hope of making inroads into the lucrative Indian market. The export will be undertaken by the private sector by sea and by railways. A bumper harvest of 23 million tons is expected this 2006-07 crop year. Last year, the country also had a bumper crop of 21.7 million tons of wheat. The surplus harvest of wheat, however, does not guarantee food security in the country. The traders mafia (that includes ministers, influential parliamentarians and the private traders plus few industrialists) in our country is very strong and the common consumer suffers the net impact of such malpractices. Government takes decisions in the name of consumers but in actual effect, these are the traders who benefit from exports/ imports and not the consumers. The profiteering tendency of the global food producers and distributors even at the cost of people’s survival is bound to create social and political upheavals. This is a harsh reality which the business people and policy makers have chosen to ignore so far. Food insecurity amidst plenty is the name of the game in food politics. Despite the fact that global economy is a food surplus economy, 852 million people (17 % of the world population) go hungry every day in the world because they do not have access to food. The chronic hunger kills more people every day than disasters, disease or war. But, all this is when there is enough food to feed the entire population of the world twice. Women in rural areas go hungry the most despite doing the bulk of the work to grow food and feed their families. Women produce up to 80 per cent of the food in developing countries, but they own only one per cent of the land. The continuation of hunger is directly related to a lack of access or entitlement to food, and to the natural resources essential to the provision of food. Food sovereignty is the right of people to define their own food and agriculture, and to protect and regulate domestic agricultural production and trade.

The aim of this paper is to forecast the quantity of potential annual e-waste generation in Bangalore city for the period 2019-2020 based on obsolescence rate method. E-waste comprises of many items but the present study is limited to seven products Personal computer, Printer, Television, Mobile phone, Refrigerator, Air conditioner and Washing machine for quantification and composition of e-waste produced. The average weight of EEE and obsolescence rate of each product was taken as per E-Waste Volume I, Inventory Assessment Manual, and UNEP. The field data were collected through questionnaire-based survey followed up with interviews where the target respondent groups and e-waste categories were predetermined to determine the e-waste flow purchasing pattern, recycling and disposal practices, and to understand the existing measures for e-waste management in Bangalore. There are three main target respondents included in the survey. The three main categories are Households, Offices (business entities and institutions) and Recyclers (Including importers and exporters, manufacturers, collectors, second-hand shops, repair shops, dismantlers, and processors of recyclable materials from used WEEE). It can be observed that the total quantity e-waste generation in each year is increasing on logarithmic scale. However, the composition of e-waste in each year is varying according to the activities in household, office and recyclers sectors. The generation of E-waste among household sector depends on the lifestyle and socio- economic status. With the increase in income there is an increase in the generation rate, but the generation rate if we observe there is a decrease in e-waste quantity due to inflation rate in the products. In business sector, the projection shows that due to advancement in technology, obsolescence rate and increasing urbanization there will be inevitable trend among increase in generation of waste in the commercial sector.
