Control of mean arterial pressure by cardiac drug infusion system using fuzzy logic controller
Vinoth, N., Krishnan, J. and Malathi, R.

The control of physiological variables presents specific challenges, mainly due to the highly nonlinear, complex behavior of biological systems. Cardiovascular system stands as a clear example, with critical situations when control is desirable and troublesome in the same time. This paper presents a fuzzy control strategy for blood pressure by automatic infusion of two commonly used drugs, sodium nitroprusside and dopamine respectively. The Mean Arterial Pressure (MAP) is regulated using the...

Dielectric studies of thiourea doped sulphamic acid single crystal
Kannan, B., Seshadri, P.R., Ilangovan, K. and Murugakoothan, P.

Thiourea doped sulphamic acid single crystals (Th : SA) were grown by slow solvent evaporation technique at room temperature and their dielectric properties are studied. The variation of dielectric constants, dielectric loss and conductivity at different temperatures and frequencies in the applied field are measured and their electrical behaviors are analyzed. The activation energy of electrical process is also determined at various frequencies and temperatures.

Effects of level of tillage on germination rate and vegetation of maize crop of benue river makurdi flood plains
Mohammed, K. M. and Umogbai, V. I.

A field experiment was conducted to determine the effects of different levels of soil tillage on soil physical properties of Benue River flood plains in Makurdi zone. The field was laid out in a Randomized Complete Block Design (RCBD) with four treatments and three replications. The treatments were ploughing and harrowing once (PH), ploughing and harrowing twice (PHH), Ploughing and Harrowing Thrice (PHHH) and No – Tillage (NT). A four – wheel drive Massey Ferguson tractor (MF 375 E), 3 –...

Traditional games and sports of special hilly tribe called toto community
Mrinal Das and Dr. Kallol Chatterjee

Traditional games and sports can form the backbone of a community which are the part of intangible heritage and a symbol of the cultural diversity of our societies. They are also an efficient means to convey values of solidarity, diversity, inclusiveness and culture which form an integral part of national and development strategies. Moreover, they reflect on different cultural expressions, and create a bridge between cultures for a better mutual comprehension. Most of the traditional games...

Determination of fluoride and some effects on the drinking waters of some wards in kaltungo local government areas of...
Danbature, Wilson Lamayi; Fai, Frederick Yirankinyuki and Ayim, Patrick

Water is essential to life. The assessment of water quality is very important as it is often contaminated. Fluoride being one of the chemical contaminants of water causes dental fluorosis, diminishes bone strength, and causes osteosarcoma and low IQ etc. In this research, a total of 30 samples (six from each location) were collected from Kaleh-Aya, Okra, Poshereng, Popandi and Gombe (as control). The samples were analyzed for fluoride using HACH DR/2000 model spectrophotometer. The results...

Microorganism combination for rapid increase of peptide yield in solid-state fermentation of soybean meal and the...
Junjun Guan, Guohao Yang, Haicheng Yin, Feng Jia and Jinshui Wang

Background: Soybean meal was used as substrate to evaluate effects of three microorganisms, Bacillus sublitis (B), Saccharomyces sp. (S) and Lactococcus lactis (L), on peptide production by solid-state fermentation (SSF) with a shorter fermentation time (such as 36h or less), and the corresponding mechanism, under the condition of liquid soybean meal dextrose medium as culture medium and soybean meal as solid substrate without other supplements, thus forming a environment of limited living...

Estimation of combining ability studies in sunflower (Helianthus annuus L.)
Khandagale, S. G., Ghodke, M. K. and Khandagale, V. G.

Combining ability studies were made in sunflower using line x tester analysis with four diverse CMS lines and four tester. Analysis of variance revealed significant difference among genotype i.e., parents and hybrids. The estimation of Specific Combining Ability (SCA) variance was higher than General Combining Ability (GCA) variance, for all the characters except head diameters which indicate non additive gene action had more effect. The parents CMS-850 A, CMS-234 A and R-363 can be...

Comparative analysis of economic efficiency of broiler and egg production enterprises in Niger state, Nigeria
Tanko, L. and Aji, D. A.

The study examines the profitability and efficiency of broiler and egg production enterprises in Niger State, Nigeria during the 2011 production season. Farm level data were collected from 120 broiler and 120 layer farmers in the State using a well structured questionnaire. Multi-stage random sampling technique was used to elicit primary data from 240 respondents. The stochastic frontier profit function was used to examine the economic efficiencies of broiler and layer farms. Both broiler...

Purification and physicochemical characterization of the α-glucosidase of the digestive juice of the snail Limicolria...
Sea Tehi Bernard, Saki Suomion Justin, Koffi Kouame Mathias, Soro Yade Rene, Kra Kouassi Aboutous and Diopoh Korej

In this study we are interested by the α-glucosidase, a protein biocatalyst from the digestive juice of a snail Limicolaria flammea which we purified by the chromatographic methods. Then the physico-chemical characteristics of this enzyme were determined. With a specific activity of the crude extract of 4.31 U/mg, purification have been done on Sephacryl S-200 HR gel then, specific activity has passed to 34.17 U/mg with purification factor of 7,93.With Anx-sepharose 4 fast flow gel,...

Bio-efficacy of certain indigeneous plants extracts against a storage pesttribolium castaneum herbst (Coleoptera;...
Srinivasan, K., Pugazhendy, K. and Rathika, R.

In continuation of our work on indigenous plants we have taken in to consideration the search for plants with potential insect pest management. Ethanol extracts of five species of certain indigenous plants screened for their insecticidal activity against the storage pest Tribolium castaneum which are known to cause maximum damage in pulses and wheat flour in storage. The tests were carried out using filter paper impreganation method at concentration levels range between 25µg-200µg/ml crude...
