Paper Title :: COMPARISON DISTILLED WATER AND CASSAVA WASTE WATER AS AN ADMIXTURE SANDCRETE BLOCKS
Author Name :: E. O. Aiyewalehinmi || S. P. Akande
Country :: Nigeria
Page Number :: 01-07
The Compressive Strength of Commercially Produced Sandcrete blocks available in the material market in Nigeria fall below minimum requirements of Nigerian Industrial Standard (NIS 87:2000) 2.5N/mm2. The purpose of this study was to develop a new sandcrete blocks made from Cassava waste water to replace Normal sandcrete blocks made from distilled water using the same materials and methods. 48 sandcrete block samples size 450mm X 150mm X 225mm were cast and controlled. The tests performed include: Sieve Analysis, Water absorption, Specific gravity and Compressive Strength. The Findings revealed that the Sandcrete blocks made from cassava waste water attained compressive strength at day 28 (4.06)N/mm2 while the Normal distilled water sandcrete blocks attained the compressive strength at day 28 (1.03)N/mm2. This indicates that cassava sandcrete blocks satisfy while the distilled failed to satisfy NIS 87: 2000 and BS 3921 requirement. It suggests that Cassava Sandcrete block is a durable building and construction material.

Paper Title :: Summarization of Malayalam Document Using Relevance of Sentences
Author Name :: Ajmal E.B || Rosna P Haroon
Country :: India
Page Number :: 08-13
Text summarization is an emerging technique for finding out the summary of the text document. Text summarization is nothing but summarizing the content of given text document. Text summarization has got so uses such as Due to the massive amount of information getting increased on internet; it is difficult for the user to go through all the information available on web. Summarization techniques need to be used to reduce the users time in reading the whole information available on web. In this paper propose a Malayalam text summarization system which is based on MMR technique with successive threshold. Here the sentences are selected based on the concept of maximal marginal relevance. The key idea is to use a unit step function at each step to decide the maximum marginal relevance and the number of sentences present in the summary would be equal to the number of paragraphs or the average number of sentences present in the text document, which can be achieved by using successive threshold approach. We apply MMR approach on Malayalam text summarization task and achieve comparable results to the state of the art.
Keywords- Maximum Marginal Relevance, Successive Threshold, Unit step function.

Country :: India
Page Number :: 14-16
Heavy metals usually present in trace amounts in natural water. Some metals are essential to human and animals but they are toxic when their limit exceeds. Their concentration increase in water due to addition of industrial wastes, sewages and domestic wastes, Iron concentrations in the sewages are very low than the permissible limit which was analysed here. Water quality of Cauvery River and Kallanai Kalvaai analysis helped to get the information's of chemical, physical, biological, and radiological characteristics of water. Water quality of these river and dam are used to measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose.

Author Name :: Prasanna Kumara T.P || N.K. Sarath Chandra Prakash || Lokesh P || Dr. Krishna Manral
Country :: India
Page Number :: 17-30
This research wasconducted to determine the effect of viscoelastic properties and Rheological characterization of carbomers. Carbomers are the generic name for a class of high molecular weight cross linked polymer of acrylic acid. Carbomers play an important role in many commercial products such as gels, creams and lotions, providing viscosity, stabilization and suspension properties. Understanding how the preparation of the carbomers can affect the final. One such factor that can affect the behavior of the carbomers is the method of dispersing the carbomers into an aqueous medium, the carbomers considered in this research were from USP grade of materials, from this investigation conducted, it was found a number of carbomers were affected by shear as a result of the method of dispersion used. Use of the shear sensitive carbomers in commercial production could require the use of low shear mixing which would result in a longer dispersion time and increased production cost.

Page Number :: 36-42
Twenty (20) samples of concrete blocks from different local government in Katsina state were measured using gamma spectroscopy with NaI (TL) detector. Three naturally occurring radionuclides and their activity concentrations were determined, that is 226Ra, 232Th and 40K. The activity concentrations for 40K ranged from 46.11 ± 1 to 826.59 ± 4.82 Bq/kg, the activity concentration of Radium (226Ra) ranged from10.19 ± 2.43 Bq/kg to 75.09 ± 4.98 Bq/kg and the activity concentration of Thorium (232Th) ranged from2.77±9.59Bq/kg to 105.13 ± 9.25Bq/kg. The highest value 826.59 ± 4.82Bq/kg was recorded from 40K; the highest value of 226Ra was obtained from the measurement 75.09 ± 4.98 Bq/kg and also the highest value obtained for (232Th) 105.13 ± 9.25Bq/kg respectively. The calculated radium equivalent of (375.10 Bq/kg) shows that it has higher value from sample BS 04 (Jibiya L.G.A) which is Grater than the recommended limit set in the OECD report (370 Bq/kg). And also when compare with (UNSCAER, 2000), the terrestrial radiation it's evident that the data obtained from measured samples gives higher value. The results obtained from other Local Governments were found to be lower than the recommended limit 370 Bq/kg for public exposure and control recommended by International Commission on Radiological Protection (ICRP) and Organization for Economic Cooperation and Development (OECD). The paper also offered Recommendations for public exposure to Radium 226 (226 Ra).

The computer-assisted testing (CAEx) is a method of construction and operation of measures using the computer. It has an important use of CTI in experimental sciences field. The CAEx equipment includes a computer interface and associated with different sensors. It allows real-time measurement of various physical parameters changes, biological. Our study is a collection of information on the types of sensors used in high schools, the appreciation of the type of teacher training teachers in the use of CAEx, measuring the level of use of this tool in experiences in class and possibly the benefits and advantages provided by this tool. In this work, we made some experiments of CAEx tool. We did a survey on the use of CAEx which was to write a questionnaire that focused on equipping schools in CAEx, training of teachers CAEx, the frequency of use of this tool and its contribution to class. We then distributed the questionnaire to teachers of physics in several Moroccan schools; This was a sample of 50. It is clear from this survey that CAEx can: - Gain time - Present values and more accurate results - Make less effort to achieve his goals At first, we presented computer-aided experiments which we have reproduced in the laboratory. In a second step, we checked the level of use of CAEx by teachers, and eventually enjoyed the benefits that bring them of CAEx.

Paper Title :: Motion of MHD Micropolar Fluid Toward a Stagnation Point Under the Influence of Induced Magnetic Field
Author Name :: Anyaegbunam F.N.C.
Country :: Nigeria
Page Number :: 48-55
A steady two-dimensional Magnetohydrodynamic (MHD) mixed convection stagnation point motion of an incompressible, viscous and electrically conducting micropolar fluid toward a stretching and or shrinking vertical surface with surface heat flux is investigated. The effects of induced magnetic field and the heat flux radiation are considered. The transformed differential equations are solved numerically by a finite-differencemethod. The results for skin friction, heat transfer and induced magnetic field coefficients are obtained. The velocity, micro-rotation and temperature distribution for various parameters are shown. The results are in good agreement with earlier studies. The present results are compared with existing results in the literature and shown to be in good conformity as shown in the resulting table and curves.
