Allelopathy of some forest trees from vriddheswar, pathardi tahsil, ahmednagar
The effects of aqueous leaf extracts of different concentrations of Butea monospermal (Lam) Taub (Fabaceae), Limonia acidissima L. (Rutaceae) Semecarpus anacardium L. (Anacardiaceae) from Pathardi Tahsil (longitude190 09? N, latitude 750 10? E) Dist Ahmednagar were bioassayed in August 2008 on germination and seedling growth of Raphanus sativus L . var. ‘Hybrid 11’. Seed germination was promoted 13 to 21% by Butea, 3.58% by Limonia while Semecarpus inhibited by 10.71% at 10-1 concentration. Data was analyzed by appropriate statistical method. Inhibition at higher and stimulation at lower extract concentrations were recorded. Pot culture experiments will be arranged.

An investigation into weaknesses exhibited by senior high school biology students in graph work in the cape coast metropolis of Ghana
The purpose of this study was to examine Biology students’ weaknesses as far as graph work is concerned. The target population was SHS 3 students offering biology as an elective science subject in Senior High Schools in the Cape Coast Metropolis during the 2009/2010 academic year. However, the accessible population was elective biology students from six schools in the Cape Coast Metropolis. At each school an intact class was randomly selected and used. In all a sample size of 230 students was used. The study revealed that elective biology students have difficulty with providing headings, an appropriate scale, and labeling the axes of graphs.

Application of EVMS technique in a cattle barn construction instead of tradditional management
Earned Value Management System (EVMS) is designed for controlling the costs and determining the periods of attracting financial credits (domestic or Rial and foreign currencies) in the project. Unfortunately, this controlling system is poorly carried out in most of the operational projects or merely its show-off aspects are highlighted. But, in reality, this system is able to predict the process of attracting costs at the beginning of the executive operation, and also, to control the amount of costs spent during the executive activities. Furthermore, the project status can be assessed in different time intervals using the key indices of this system and different cost analyses acquired from these indices. The aim of this project is the examination of the concepts involved in the earned value method, the methods and metrics it employs as well as the performance measurements and methods of forecasting project progress that are used. A case study regarding the construction of a Cattle Barn in Qazvin city, an actual project, is utilized to illustrate the comparison between traditional methods and the EVMS method. By utilizing information obtained when employing the earned value method with the project, findings the valuable would be early warning with regard to a problematic situation, it is possible to take steps to correct the problem before too much time has elapsed. It is possible to make more informed decisions about the project's direction with accurate forecasting. With accurate forecasting, it is possible to make better decisions with regard to issues that are outside the scope of the project but that may be affected by the project's progress. Sponsor confidence is boosted when a view of progress is available that is open and that can be verified.

Bacteriological Status of Water Melon (Citrullus Lanatus) Sold in Mile III Market, Port Harcourt
The study was carried out to investigate the bacteriological status of freshly sliced water melon in mile III market Port Harcourt. A total of 20 sliced water melons was collected while one whole water melon collected was used as control in this study. The control sample was properly washed with sterile water and sliced aseptically. A sterile knife was used to cut 1.0g from each water melon sample and homogenized on a sterile mortar and pestle. The resultant homogenate was pipette (1.0ml) into 9.0ml of distilled water and serially diluted. The 104 dilution was plated out on Nutrient and MacConkey agar plates respectively using spread plate technique. The plates were incubated at 370c for 24 hours. The cultured plates were examined for colony growth and identification of isolates. The result showed that bacteria isolated from the sliced water melon were Staphylococcus aureus, Escherichia coli , Bacillus spp and Proteus with percentage bacterial count of 414 (45.8%). 324 (35.5%), 144 (15.8%), and 30 (3.3%.) respectively. The control sample showed a scanty growth of staphylococcus aurus. In conclusion, since the control had only a colony of staphylococcus on culture plate after it has been hygienically processed, contamination of the sliced water melon maybe due to poor sanitary condition employed by the vendors during processing and packaging. This is of public health concern as these organisms are known causes of food born diseases and food poisoning.

Bayesian Analysis for Epidemiological Study of Child Mortality on the District Level of Uttar Pradesh
In this study an attempt has been made to describe the analysis of epidemiological study by Bayesian methods and apply this methodology to district level child mortality of Uttar Pradesh to assign rank to each district for rural and urban separately. The specific objectives of this study are to analysis of epidemiological study by use of fixed effect modeling and random effect modeling in Bayesian setup. To assign rank to each district by this suggest applying strategies to reduce child mortality in those district for those ranks are poor in Uttar Pradesh. The modified retrospective cohort study design used here. For fixed effect modeling beta-binomial modeling approach is used and for random effect modeling logit link function is used. The posterior estimates came in both cases under squared error loss function.

Channel equalisation with an efficient variable step-size transform domain Adaptive algorithm
Equalization techniques compensate for the time dispersion introduced by communication channels and combat the resulting inter-symbol interference (ISI) effect. The purpose of an adaptive equalizer is to operate on the channel output such that the cascade connection of the channel and the equalizer provides an approximation to an ideal transmission medium. This paper compares existing adaptive algorithm for channel equalisation for both DFT and DCT based OFDM system. Simulations results show that performance of Transform Domain Variable stepsize Griffith LMS(TVGLMS) algorithm in channel equalization performs with better convergence speed and better error misadjustment than the LMS algorithm. Further simulation results shows that DCT based OFDM system outperforms DFT –OFDM in terms of BER and PAPR .

Compare Hot Forming and Cold Forming Rolling Process
In metalworking, rolling is a metal forming process in which metal stock is passed through a pair of rolls. Rolling is classified according to the temperature of the metal rolled. If the temperature of the metal is above its recrystallization temperature, then the process is termed as hot rolling. If the temperature of the metal is below its recrystallization temperature, the process is termed as cold rolling. In terms of usage, hot rolling processes more tonnage than any other manufacturing process, and cold rolling processes the most tonnage out of all cold working processes. This article describes the use of advanced tubing inspection NDT methods for boiler and heat exchanger equipment in the petrochemical industry to supplement major turnaround inspections. The methods presented include remote field eddy current, magnetic flux leakage, internal rotary inspection system and eddy current.

Considering any relation between organizational culture & suggestions system
The present research intends to study any relation between organizational culture and suggestions system. It is an explanatory one from among different types of applicable researches and from method viewpoint. Therefore two separated questionnaires were applied for this purpose. The first one is related to organizational culture with 23 closed questions. The second one is related to measuring any cooperation through suggestions system. Upon ensuring about narration and survival of measuring tools, both questionnaires were distributed among members of a sample consisting of 30 persons of a statistical population including headquarter personnel of quarter areas of Education Department. According to the findings, there is a meaningful relation between organizational culture parameters and suggestions system. Finally there are some proposals for betterment and upgrading all cultural dimensions in order to have more promotion of suggestions system in mentioned organization.
