Our country India is the largest producer of banana (Musa sapientum ) contributing to 27 % of total world production and so annually large amount of banana pseudo stem containing nearly 62 % cellulose fibers are left unused on the plantation floor to serve merely as organic manure. Thus it is relevant, important and also economically profitable for our country to make it an industrially acceptable reinforcing material.

Chromium has been widely used in various industries like textile, leather, paint industry and many other industries. Since hexavalent chromium is a priority toxic, mutagenic and carcinogenic chemical when present in excess, it is very much required to remove chromium from effluent before allowing it to enter any water system or on to land. In the present work the removal of Cr(VI) by adsorption on the sugarcane bagasse sodium hydroxide modified sugarcane bagasse were studied. The effect of pH and initial metal ion concentration on the biosorption of Cr(VI) ions were investigated.

The article mentions concepts, benefits and types of online advertising. The author then suggests some solutions to strengthen the effectiveness of this activity in the Library of University of Social Sciences and Humanities (Vietnam National University – Ho Chi Minh City).

In this study an attempt was made to use a bio coagulant for treating chicken abattoir waste water. Moringa Oleifera Leaves were used in two different forms- one in the form of Moringa Oleifera Leaves Powder (MOLP) and the other in the form of Activated Carbon prepared from Moringa Oleifera Leaves (MOLAC).

In 21st century the world is facing the critical issue of waste water management, textile industry are the top most red industries in the world. Industrial processes create a variety of wastewater pollutants, highly turbid which are difficult and expensive to treat. In this paper (basic dye) camel ink is treated by using electro-coagulation process. Experiment is carried out by using batch mode reactor in a laboratory using aluminum electrodes. UV Spectrophotometer is used to carry absorbance. Experiment is carried out by using aeration with electro coagulation.

Cloud storage services have become increasingly popular. Because of the importance of privacy, many cloud storage encryption schemes have been proposed to protect data from those who do not have access. All such schemes assumed that cloud storage providers are safe and cannot be hacked; however, in practice, some authorities (i.e., coercers) may force cloud storage providers to reveal user secrets or confidential data on the cloud, thus altogether circumventing storage encryption schemes.

This paper uses the metaphor of University Remodeling as a framework for analysing students’ choice of a private university and repositioning the university through rebranding of its professors. Remodeling the university involves reconstructing competencies and strengths of the institution. These elements are critical to the growth of the university. Managing growth requires understanding of the factors influencing students’ choice of a university, institutional commitment towards improving these factors, and rebranding the university to differentiate itself from its competitors.

The usage of smart phone among people is increasing rapidly. Now days we are dependent on our mobile phones, if we forget the phone at home or somewhere place that time we can access the mobile phone remotely using the application. By using this application user can send e-mail in our mobile even if mobile is very far from us, by sending a single text message we can send e-mail from our remote mobile. To accomplish this task first step we need to turn-on the cellular data for that we have to send SMS to our mobile through remote mobile.

This is a review paper on image segmentation. Basically we have tried to focus our work on image segmentation using fuzzy logic approach. In this paper we have discussed some basic concept of image segmentation and the application of fuzzy c-means algorithm in image segmentation. We have implemented this algorithm using MATLAB. This is basically the implementation part and now we are working on the efficiency respect to other fuzzy clustering algorithms which can be used for image segmentation.

Crude oil is a natural endowment to the people of Nigerian. Hence, refineries were positioned to provide finished petroleum products to both domestic use and for export. Till date, Nigeria still depends largely on the importation of petroleum products for both domestic and industrial applications. The aim of this research work therefore, is to find out the possible causes of this downward trend in the productivity pattern of our Refineries using WRPC as a case study. A survey approach was adopted in this work using questionnaires.
