Several surgical methods have been described for the treatment of fresh ruptures of the Achilles tendon. We operated 20 patients for a ruptured Achilles tendon. This study concerns 14 men and 6 women with a mean age of 32 years, all operated by the technique Chigot. We regretted having 12 minor complications advanced favorably. One patient broke a second time his tendon two months after surgery. In 75% of patients, previous sports activity was found. Several studies confirm the low complication rate of this technique particularly recurrent rupture compared to conservative treatment. The technique allows Chigot strengthening the Achilles tendon ruptured without resorting to the fascia of the triceps with a low morbidity.

Osteoblastoma is a rare benign bone tumor, occurring during the second and third decade with a male predominance of spinal preferential seat secondarily the long bones of the limbs, rarely ends Its diagnosis is based on a set of arguments; clinical dominated by doctors located, the imaging objective lyric picture surrounded by sclerotic bone reaction and can invade soft tissues, and especially the pathological examination confirmed the diagnosis highlighting a significant proliferation of osteoblastic cells with the presence of osteoid tissue bathed in a lush and richly vascularised connective tissue. Treatment is exclusively surgical resection is complete and guarantee the prevention of recurrence. We report the case of an osteoblastoma of the ankle in a young adult revealed by localized pain and functional impairment. Standard radiography made was considered completely normal and the persistence of complaints CT was performed but was misleading suggestive of osteochondrosis. This is a pathological examination performed on specimens which helped rectify the diagnosis. The suites in this patient were simple, very satisfactory functional outcome osteoblastoma tumor is easily diagnosed if you think, easy treatment if done right.

Kaolin plays a very signi?cant role in the industrial aspects of life and new ones are still being discovered. It is a unique industrial mineral and very widely utilized in industry and its usage is in?uenced by its functional properties. However, the Egyptian kaolin is hard and massive. It is also low grade so that it needs beneficiation to be suitable for different industries. The kaolin used in most of the industrial applications should have very fine size distribution (80-90% by weight below 2 µm) and should be of high quality especially for applications like plastics, paints, paper industry, cosmetics, and pharmaceuticals. Moreover, great attention in recent years has been paid to the industrial applications of intercalated nano-composites where kaolin or clays are extensively used. Therefore, new technologies must be developed to achieve good separation, especially when treating these finely disseminated particles. One of such recent technologies is the bio-processing where micro-organisms could be used for removing these coloring materials. In this paper, the role of micro-organisms on the surface properties of the kaolin single mineral has been studied through zeta potential and adhesion measurements as well as the adsorption experiments. Complete characterization of both single mineral and bacteria isolated from its surface has been done using XRD, SEM, and FTIR as well as morphological and biochemical identification of bacterial isolates.

Longitudinal, shear ultrasonic velocities and attenuation were measured in different compositions of the glass systems of 10TeO2.15BaO.(75-x)B2O3.xNiO and 10TeO2.15BaO.(75-x)B2O3.xWO3 (where x= 0 to 1 mol% in steps of 0.2) at room temperature by using pulser - receiver technique at 5 MHz. The glass samples were prepared by conventional melt-quenching method. The amorphous nature of the samples were ascertained using X-ray diffractometry (XRD). The density of the glass samples were measured by relative measurement method. The measured experimental values are utilized to evaluate elastic moduli, Poisson’s ratio, acoustic impedance, internalfriction, microhardness, Debye temperature, and thermal expansion coefficient. Trends of the co-ordination number, cross-link density, mechanical and thermal stability for the systems are discussed in terms of the structural changes taking place due to variations in composition.

One of the main problems in sampling survey is the optimal allocation of resources. The solution of this problem is rather arbitrary due to the fact that no best allocation is defined. In this model, the allocation problem was to find the allocation of a sample to strata which minimizes cost of investigation. The idea of optimal allocation under a multivariate stratified sampling based on an alternative approach earlier worked on by Diaz- Garcia and Ranos– Quiroga was applied. The matrix of the variance-covariances of the vector of the stratified variables was obtained. An emperical data from a household survey conducted in Ogun state was used. The frame consisted 880,970 households in the twenty local government areas (LGA) of Ogun state. Each of the 20 LGAs that made up the state was seen as a stratified cluster. Post stratification in this study ensured that some variables that are suitable for stratification was achieved after selection of the sample. The four characteristics of interest were occupation, income, household size and educational level. The study transformed all variables in the stratified sampling plan by using dummy variables ranging from 1-3. The estimates used in the computation were calculated using statistical software Splus. The post stratification estimator ?st does not have the same variance as the stratified sample mean. Stratification produced a gain in precision in the estimation of characteristics of the household survey. The results of the estimates in the study revealed that proportionate allocation can lead to smaller sampling variances than for simple random samples of the same size.

Present investigation deals with the assessment of fecundity of catfish Macrones vittatus (Bloch, 1794) collected from Bhategaon dam, Maharashtra during January to December 2011. The mean value of fecundity produced by an individual fish was found to vary between 2562 to 26316. In Macrones vittatus (Bloch, 1794) maximum number of eggs was observed in 162 mm in total length and 30065 mg in body weight, whereas, minimum was observed in 102 mm in total length and 9265 mg in body weight. The relationship of fecundity with other parameters such as Total length (TL), Total weight (TW), Ovary weight (OW) and Ovary length (OL) were found to be linear and non linear and the values of correlation coefficient (r) was 0.92, -0.11, 0.93 and 0.81.

Nahj-al-Balagheh means a rhetorical way. It is a noteworthy series of Imam Ali’s words and syaings which guide human beings in different occasions and on various topics. Its words are considered the strongest words in guiding human beings after words of Quran and the Prophet Muhammad. Nahj-al-Balagheh is considered as the best path toward prosperity and human development. One of the topics which Imam Ali (A.S.) mentioned in different parts of Nahj-al-Balagheh is the topic of guidance and consulting. Guidance and consulting are regarded as the key issues in the development of behavior and personality. Based on this, the purpose of this paper is to investigate the effective factors in guidance and consulting. This was a descriptive paper in which the aim was to analyze either content or meanings. To reach such analyses, journals, websites, and analyses of different books were used. This paper includes two parts. In the first part, the effective factors on guidance and consulting are investigated as well as the role of a consultant, his characteristics, methods of consultation, and topics of consultation are sought from Imam Ali’s point of view and today’s science. In the second part, a short contrastive analysis between Imam Ali’s words/sayings and today’s science is conducted. The implication of the study is accepting the fact that science alone is not enough to educate human beings and that it is necessary to implement religion and the art of rhetoric to be able to guide humans towards education and prosperity.

Central focus of the study was to check perception of students concerning importance of teamwork. Students belong to Pakistani and English origin were unit of analysis in our study who were approached to make their opinion regarding teamwork. A questionnaire was prepared with likert scale from 1 strongly agree to 5 strongly disagree for the sake of collecting data. Later on normality, reliability and t test were applied to check perceive importance of teamwork. Findings revealed that both societies are agreed on common benefits of teamwork and null hypothesis were partially accepted.

Weather Generators (WGs) are widely used in water engineering, agriculture, ecosystem and climate change studies because observed climatic series have deficiencies related to length, completeness and spatial coverage. WG models can simulate daily temperature data in a few parametric ways. One way is to simulate daily minimum (Tmin) and maximum (Tmax) temperatures using an autoregressive model. Another way consists of the simulation of daily average temperature (Tav) and daily temperature range (R) and then the calculation of Tmin and Tmax indirectly. In this study, four different algorithms were assessed for daily temperature in combination with a well-tested weather generator. M1 and M2 algorithms simulated the daily Tav and R values directly and Tmin and Tmax indirectly. M3 algorithm simulated Tmin and Tmax and M4 algorithm simulated Tmin and Tav directly and the other variables indirectly. The results showed that each algorithm could perform better in simulating primary variables (which are simulated directly). This issue was more considerable in relation to daily R values. M2 overestimated the cross-correlation coefficients of this variable because of the assumption of a strong autocorrelation structure between primary variables in the WG model. M3 and M4 outperformed the other algorithms in relation to most studied indices. This study showed the importance of choosing the best temperature generation algorithm according to the requirements.

The concepts of cultural investment and lifestyle are subjected to one of the most common attitude in the recent decades. The cultural investment is the collection of the knowledge and advantages which individuals apply and preserve it to reach to their social situation; and also, the lifestyle is subjected to the collection of approaches, values and behavior patterns; in most cases, the elements of a life are gathered along together forming numbers of people; thus, the lifestyle can be defined as the social classes and groups which people follow these behavior, beliefs, norms and social values and patterns emerging particular establishment of cultural/ educational symbols possessed to themselves as their social class. The main purpose of the study is to evaluate the effect of cultural investment on the lifestyle; the study is carried out as a scale-based approach. The required data were selected and gathered by a questionnaire from a 260 people sample of secondary school students in Markazi province; in addition, the study was taken up as a multi-step cluster sample. In the study, the theories of Anthony Giddens and Bourdieu were used to assess and measure the cultural investment and lifestyle. According to the indices like body management and consumptive norms forming lifestyle and going to movie, listening to the music, reading a book, going to the concert, visiting museum and photo gallery forming the cultural investment. Due to the main aim of the present study, the evaluation of cultural investment and lifestyle were strongly emphasized and the finding indicated that there is a positive significant relationship between respondents cultural investment with each dimensions of their lifestyle.
