The aim of this study was to develop regression equations for stature estimation using the upper limb bone in Korean individuals. A total of 105 samples (55 men and 50 women) obtained from cadavers were used for developing equations. Bones with obvious pathologies or healed fractures were excluded. The coefficient of determination (r2) of the variables was slightly higher in men than in women. ...

Three time-series models (regression, decomposition, and Box-Jenkins autoregressive integrated moving averages) were applied to national surveillance data for campylobacteriosis with the goal of disease forecasting in three US states. Datasets spanned 1998-2007 for Minnesota and Oregon, and 1999-2007 for Georgia. Year 2008 was used to validate model results. Mean absolute percent error, mean sq...

Introduction: Sound absorption coefficient determination is one of the most important factors among material selection for indoor noise control. The objectives of this study were: 1) comparison sound absorption coefficient of different materials by standing wave ratio and transfer function methods, and 2) developing a regression model in adjusting provided results. Methods: In this study, 46 a...

The occurrence of contaminants in wastewaters, and their behavior during wastewater treatment and production of drinking water are key issues to re-use water resources. The present research aims to remove caffeine from aqueous solutions via adsorption technique, using Multi-Wall Carbon Nanotubes (MWCNTs) as an adsorbent under different experimental conditions. The processing variables such as p...

the partition coefficients (p-values) of certain new potential, stereoselective, reversible, long-acting local anesthetics have been determined in an n-octanol/ phosphate buffer system. these are derivatives of 2-phenoxyethyldialkylamine hydrochloride, and almost all of them are readily soluble in water. their aqueous solutions have shown different absorption maxima, and these have been used qu...

Background: An effective learning procedure is depended on the usefulness of the education system. In this context, education policymakers focus on recognizing factors influencing student learning outcomes. This study aims to investigate job alienation in high school teachers and its impacts on their job performance and quality of life. Materials and Methods: This descriptive study was conduct...
