The development of self-compacting concrete (SCC) was a significant step towards effectiveness at building sites, realistically producing prefabricated concrete rudiments, improved working conditions and better quality and emergence of concrete structures. By addition of fibres to SCC, bar reinforcement can be replaced and the performance of concrete structures improved. Self-compacting fibre reinforced concrete (SCFRC) combines the benefits of SCC in the fresh state and an enhanced performance of fibre reinforced concrete in the hardened state. With the special characteristics of SCFRC new fields of application can be explored. The objective of the study is to determine and do the comparative study of the properties of concrete containing no fibres and concrete with fibres, as well as the comparison on the effects of different type and aspect ratio of fibres to the self compacted concrete. This investigation was carried out using several tests, which included workability tests of SCC, compressive test, indirect tensile test and flexural test.

This discourse is directed at highlighting the importance of financial accountability in school management. Budgeting is a managerial function that enables every administrator to efficiently utilize all financial resources available to the organisation. Financial accountability will be difficult to achieve in the absence of good budgeting. The role of the school administrator in effective budgeting, as well as the challenges to effective budgeting in the face of a negatively skewed national budgetary allocations are also highlighted. It concludes that effective budgeting will be difficult to achieve in the existence of financial uncertainties, policy inconsistency in educational development and increasing pressure on education facilities arising from growing demand for formal education in the public school system. It recommends the development of an education policy that will have a minimum life span of twenty years; and the development of a body of school system personnel that is compliant to the digital system of information management. A reliable information base and efficient information management system will go a long way in facilitating good budgeting practice and effective accountability.

This paper examines the causal relationship between energy consumption, economic growth and prices evidence from Pakistan by using the annual time series data from 1980 to 2011. Co-integration, Engle Granger test and Error correction techniques are used to achieve the objective. The empirical results of co-integration test shows that energy consumption and economic growth are cointegrated. In addition, causality test results reveal that there is a short-run and long-run Granger causality running from economic growth to energy consumption for Pakistan. The empirical results of this study provide policy makers a better understanding of energy consumption-economic growth relationship to formulate energy policies in Pakistan. In this study, economic growth cause energy consumption, it suggests that the implementation of energy conservation policies may be implemented with little or no adverse effect on economic growth. Therefore, there is relatively more scope for energy conservation measures as a feasible policy in Pakistan.

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.
