The aim of the study was to compare foot profiles and ergonomics determined by foot
pressure distributions in dynamic balance skills in footballers. The hypothesis of the study
is that soccer players with a normal curved foot profile will perform better in dynamic
balance skills. Thirty-three (18 males, 15 females) volunteer university student licensed
footballers (age: 19 ±1 year) participated in the study. Foot pressure distributions of the
athletes were classified using the Chippaux-Smirak index. Dynamic balance skills were
measured using a wireless portable balance system (Sigma System Cosmo Gamma, Italy)
with 30-second scoring. For statistical comparisons, One-Way Analysis of Variance
(ANOVA) was used to analyse parametric data and Kruskal Wallis-H Test was used to
analyse non-parametric data. Spearman Correlation Analysis was used for correlations.
As a result of the study, it was observed that there were significant differences between 3
different foot profiles in the single foot (right) dynamic balance values in favour of normal arch,
low arch and high arch, respectively. In addition, in the in-group comparison of foot profiles,
it was found that the outward and inward tilt percentages in the right foot dynamic balance test
were significantly different in favour of the outward slope in all 3 foot profiles (p≤0.05). The
fact that the significant difference in dynamic balance findings originating from the foot
profile is only seen in the right foot test supports the hypothesis and is thought to originate
not only from having a normal hind foot, but also from the influence of the dominant leg.
It can be said that foot profiles are partially effective on dynamic balance performance and
the motor strategies used by footballers during this performance.

The paper carefully analyses the impact of information technology on business process re-engineering with respect to organizational perspectives. This study recommends an outline for simplifying business process reengineering efforts in the direction of competitive firms. The framework was examined using sample data from the respondents who are all senior officers. The review outcomes specify that managerial innovation, market force and competitive force positively affect information technology implementation, which in turn elicit variations or business process in terms of workroom, labour force and commercial structure. The work formulates hypothesis for the factors that affect implementation of information technology in an organization and thereby proposes a model for implications of results.

Mutual funds are moving rapidly towards financial market development in response to huge market demand in Iran.so what is needed is a useful and applicable method for appraising and selecting them. Performance evaluation is one the most important point in investment .therefore, in this research we tried to compute and compare the performance of mutual funds by different models and compare them to market. So we have chosen 14 active mutual funds during the year 2008 to 2012 and calculate the risks and returns of these mutual funds, then we analysed hypotheses. Results show that performance evaluation of modern and postmodern theory gives different ranking. At this period some mutual funds showed better performance than market and some on the contrary .Also results show that postmodern portfolio criteria were more successful for predicting return than modern criteria. At the end results of research recommend the use of postmodern criteria which are based on downside risk.

In this paper, we solve the integro-differential equation by using new integral transform called Tarig transform. New theorems for the transform of integrals are introduced and proved.

The denoising procedure attenuates the image noise while preserving its edges and fine details. In computed tomography, images are degraded by additive white Gaussian noise because of different acquisition and systems errors. Due to noise existence, specialists may encounter certain difficulties to analyse or extract the useful information from noisy images. This paper presents a novel implementation of the phase preserving algorithm to denoise CT images. The phase preserving is a very powerful noise reduction algorithm but it tends to remove specific small details from the processed CT images supposing these details as noise. Therefore, the Wiener filter is used along with the latter algorithm to reduce the noise and aids in conserving the minor medical details. Moreover, selected adjustments to the phase preserving algorithm are applied to obtain a better image contrast and quality. The performance of the proposed scheme is assessed on naturally and synthetically degraded CT images using the universal image quality index (UIQI) metric. Results show major improvement not only in noise attenuation but also in preserving the small details.

In this paper, we present a reliable combined of Elzaki transform and homotopy perturbation method to solve Burger's equations. The analytical results of the equations have been obtained in terms of convergent series with easily computable components. The nonlinear terms in Burger's equations can be handled by using of homotopy perturbation method. The results tell us that the method is more efficient and easy to handle such partial differential equations.

A study on thin sections, core, and dynamic reservoir in the considered region indicates that dolomite, as one of the diagenetic processes, plays an important role in determining reservoir characteristic. With regard to the available studies, it is obvious that porosity of Sarvak reservoir varies between 2.5 to 3 percent and its estimated permeability is between 0.01- 10 millidarcy. According to the research, one ramp type carbonate platform has been determined in the studied field of Sarvak formation. The formation carbonate facieses consist of framework grains. The framework grains consist of skeletal fragments such as foraminifers, brachiopods, echinoderms, algal fragments, ploids, and minerals. Moreover, the minerals consist of calcite, dolomite, anhydrate, cloy minerals, components which include organic materials, and finally calcareous matrix which is formed in dolomite samples of very fine anhedral and subhedral dolomite crystals.
