Nickel (II) complexes and Copper (II) complexes with the two ligands TPA and 2-N-benzyl TPA with nitrate anion are prepared. The isolated solid complexes are subjected to various physical measurements, such as conductivity measurements, and spectral behaviour apart from the chemical analysis.

In mineral bio-beneficiation, it is very important to understand the microbial surface characteristics and its behaviour onto the mineral surface. Bacillus cereus bacterium has never been used before as a bio-reagent for separation of different mineral systems. In this paper, complete characterization of such type of bacteria, isolated from Egyptian iron ore surface, including gram stain, growth curve, Biolog microbial identification, Zeta potential measurements, FTIR measurements, Scanning Electron Microscope, SEM as well as protein and polysaccharide analysis have been studied. The results confirmed that Bacillus cereus is a gram positive bacterium, rod shaped, smooth and circular with different types of by-products as polysaccharides, carboxylic acids and amino acids that gives an amphoteric behaviour on the cell surface. The results of zeta potential showed that the iso-electric point (IEP) of iron oxide (? 6.3) is significantly displaced to lower values (? 2.2) after treatment with the bacterial isolates which indicates the bacterial hydrophobic effect. This is in agreement with FTIR results which confirmed the formation of hydrogen bond between OH group (of the polysaccharides part) and/or the COOH group of both the polysaccharides or the protein fractions of the bacteria with the positively adsorption sites of hematite lead to a reduction in the zeta potential of its surface to be close from that of the bacteria itself. The results obtained showed a better affinity of Bacillus cereus to hematite mineral and could be used in separation of such mineral from its associated gangue minerals.

Various companies have and are planning to market their products into the rural areas. This paper basically talks about all those problems that the Co(s) may or have faced in promoting their products in the rural markets. Different challenges exist for the managers in how to best market their brands and establish themselves amongst rural people. In addition to the challenges & hindrances, the report also focuses on many opportunities that basically attract the marketers to come and promote their products. A vast potential exists in the rural areas that has been left unexercised for a long time. Now due to the saturation point that has or is about to be reached in the Urban & Semi-urban markets, the Co(s) are focussing now onto the rural areas and trying to capitalise on the great potential that the rural areas have in store. Thus the research paper covers all these aspects quite extensively to present the deep insights that prevail in the rural market scenario.

The objectives of this paper were to show the impact of corruption on some macroeconomic variables as well as simulate a shock to corruption and view its impact on those variables for the period 1980 to 2010. To achieve these objectives, a VAR model was used, along with its uses namely the impulse response functions and the variance decomposition. Variables used include the GDP, life expectancy, investment, government expenditure, inflation rate, oil revenue, government revenue and corruption. Findings from the simulations using both the impulse response functions and variance decomposition show that corruption explains a considerable portion of economic development. It also shows the negative effects of corruption on economic growth and the indirect effects as well, through other variables of interest especially investment, life expectancy and oil revenue. Conclusions reached show that the effects of corruption on macroeconomic variables are long term in nature and it tends to increase over time. The implication is that if corruption is not tackled aggressively, low economic growth will continue unabated in the country.

Communication is the god given gift that enables intellectual and cultural exchange and builds up our competence in social behaviour. So now we are living in the information age. The internet and cloud computing has taken communication to unimaginable attitudes. Cloud computing entrusts remote services with a user's data, software and computation. But many questions arise when we think of security. Is Cloud computing communication private and security? But encrypted messages can still be tracked revealing who is talking to whom. The term Cloud Computing refers to the concept where the shared servers provide resources such as data, software to the clients. In order to use a Cloud service all you need is a web browser and an internet. The biggest Disadvantage in cloud computing is the data security. Because the data that is being stored in the cloud will be stored in the cloud provider’s server and hence this results in hacking of data by unauthorized person. In the business model using software as a service, users are provided access to application software and databases. The cloud providers manage the infrastructure and platforms on which the applications run. In this paper we gave our proposal, how we can secure our data in cloud computing. Our idea is based on implementing the Spread spectrum Image. Steganography’s (SSIS) in cloud computing platforms .we hope it will be very beneficial for the user who loves cloud platform but hesitating to use because of the data security issue.
