Knowledge worker productivity measurement using fuzzy analytical network process (FANP)
It is commonly recognized that knowledge is the only source of core competence in the knowledge based companies, but the productivity rate of knowledge workers is always low. Based on knowledge workers’ characteristics, this paper identified factors influencing the productivity of knowledge workers and then presented improvement strategies of productivity. Finally, it...

On spectral-homotopy analysis solutions of steady magnetohydrodynamic (MHD) flow and heat transfer from a rotating disk in a porous medium
In this paper, a new computational technique was used to solve a system of nonlinear second order equations that govern the steady magnetohydrodynamic(MHD) flow of a viscous incompressible and electrically conducting fluid past a rotating disk in a porous medium. Approximate analytic solutions are found and the effects of ohmic heating and viscous dissipation on the fluid...

Competitive effects of redroot pigweed (Amaranthus retroflexus) and lambsquarter (Chenopodium album) on potato
In order to study the effects of redroot pigweed and lambsquarter densities on potato yield, an additive experiment were conducted in 2004 and 2005. This experiment was done in split plot based on randomized complete block design with four replications. Treatments were two weed species in main plots and weed density in sub plots (0, 2, 4 and 8 plant per...

Sexual selection and evolution of male and female choice in genetic algorithm
Variety and diversity of population are essential for convergence to global optimal in genetic algorithm. In this study, the concepts of fitness distribution, expected and cumulative fitness distribution, reproduction rate and loss of diversity are defined for a sexual selection mechanism, and their performance of this type of selection mechanism is studied theoretically. Then...

Osteoid osteoma of the radial shaft: An unusual location case report and literature review
Osteoid osteoma has been found in nearly all bones and usually treated with radiofrequency ablation or laser photocoagulation. We reported a case of a radial shaft osteoid osteoma in a 37-year-old man and also reviewed the reported literature. The patient was presented with pain and swelling in his right forearm; conventional radiographic examination of forearm seemed to be...

Larvicidal activity of extracts from different parts of Neem (Azadirachta indica) against Aedes Aegypti mosquitoes’ larvae
Dengue is one of the major health problem in many countries. The genus Aedes in which Aedes aegypti (Family: Culicidae) mosquito belongs to, is the major vector of dengue fever disease. Search for larvicidal active compound(s) is one of the several attempts to find effective and affordable ways to control this mosquito. The aim of this study is to investigate...

Permeability characteristics of pumice-bentonite mixtures in comparison with sand-bentonite mixtures
Environmental pollution is a significant concern around the landfill sites, waste repositories and other similar wastewater storage and treatment basin and ponds. Pumice is an abundant natural material in Kayseri, Turkey and therefore, permeability characteristics of pumice-bentonite mixtures were investigated in comparison with commonly used sand-bentonite mixtures. Four...

A statistical analysis on skinfold thickness and measurement of body composition for Chinese adults
The purpose of this study was to evaluate developmental mechanism and characteristics of skinfold thickness and body composition among Chinese adults of Han nationality. Sampling measurement method was applied to acquire the indexes of height, weight, cheek skinfold thickness, triceps skinfold thickness, biceps skinfold thickness, subscapular angle...

Prediction of compression index using artificial neural network
Over the decades, a number of empirical correlations have been proposed to relate the Compression Index of normally consolidated soils to other soil parameters, such as the natural water content, liquid limit, plasticity index and void ratio. In this article too it has been attempted to establish a correlation between compression index and physical properties for the clayey...

Trace elements changes in the appendix of rabbit infected with Eimeria coecicola
The parasitic protozoa, Eimeria coecicola, causes intestinal coccidiosis in rabbits and, thereby, enormous economic losses in rabbit farms. This study aimed to investigate the trace elements changes in the appendix of infected rabbits with E. coecicola. Rabbits were orally infected with 50000 sporulated oocysts of E. coecicola, began to shed parasitic oocysts...
