Effects of occupation and physical features on musculoskeletal pain: Correspondence analysis
The objective of this work is to evaluate the effect of occupation and physical features on musculoskeletal pain location. One thousand, nine hundred and eighty seven (1987) voluntary adults participated in the study from 7 regions of Turkey in 2006. Subjects with musculoskeletal pain of at least one month's duration that had been recurrent minimally twice in any regions of the body and who had not taken any...

Directory knowledge, query stream and weighted state space tree based automatic web query classification
Optimal automatic classification of web queries aid in improving the performance of search engines. To automatically classify web queries into predefined topical categories, a novel approach which transforms a classification problem to a search problem in the state space tree is proposed. The topical categories are converted to a state space tree. The directory search results and query stream are used in determining the...

High temperature oxidation behaviour of a Ni based superalloy produced by mechanical alloying
In this study, Ni based superalloy powders (75% Ni, 20% Cr, 4% Al2O3, 0.6% Ti and 0.4% Y2O3), were mechanically alloyed for up to 8 h and were compacted and sintered at 1200°C. Sintered samples were hot-deformed at 1200°C for various amounts and secondary recrystallisation was applied at 1325°C for 1 h. Isothermal oxidation tests were conducted at 1000°C for up to 100 h in air. Surface...

Performance of Prosopis africana peel powder (PAPP) as a novel sorbent for remediating malachite green contaminated aqua system
This study was designed to investigate Prosopis africana peel powder (PAPP) as a potential, local, cost-effective, readily-available coagulant for remediating dye-contaminated water and compare it with activated charcoal (a standard coagulant).PAPP was prepared and characterized using standard procedures. Preliminary characterization of the malachite green (MG) contaminated water was carried out...

Performance analysis of modeling framework for wind speed prediction in wind farms
This paper focuses on the analysis of prediction of wind speed in the wind farms. The performance of modeling can be analyzed by using the real time data with different heights of the wind mill. Artificial Neural Network is used here to develop models for predicting wind speed in wind farms. The models are mainly based on back propagation neural network and radial basis function neural network. The wind speed prediction...

Antibacterial activity of the methanol extracts of two endemic Sideritis species of Turkey against plant pathogenic bacteria
Sideritis condensata Boiss. & Heldr. (SC) and Sideritis erythrantha var. erythranthaBoiss. & Heldr (SE) are endemic species in Turkey. The extracts of the endemic species were investigated for antibacterial activity against thirteen plant pathogenic bacteria in vitro by using the agar diffusion method. Statistical differences within bacteria were important at p <...
