The purposes of this study were to describe and compare the techniques used by elite world triple jumper and the Algerian elite team to determine the impact of distribution modality phases allowing the elite to exceeds 17-meter. Our subjects were two world elite 2009 and two Algerian national elite 2013. In the lack of new technology Modern measuring instruments kinematics or kinetics, our study based in measure of the Phase distribution ratio as measure of Stride length Jump distance. That literature review two schools, the Russian technique (which emphasizes the hop phase) and the Polish technique (which emphasizes the jump phase). Our aims for this study are: Are there any statistically significant differences between the results of the samples in the distance achieved? Are there any statistically significant differences between practical Ratio relative distances (world 2009-national 2013)? Are there any statistically significant differences between Stride length phase distances (world 2009-national 2013)? For that, we have chosen the analysis of variance and correlation of the distances achieved in each of the phases with the official distance of jumper and "T" student to compare implementation distribution of phases (hop, step and jump) with the results accuses. Based on the practices and weaknesses of elites in practice, we confirm: (1) All the samples practice the Russian technique as model in the distribution of the phase ratio; (2) The problem of our elites is in the hop phase distribution and its relationship with other phases; (3) Improve achieve horizontal vertical velocity in hop phase as solution.

Background: Dry eye disease (DED) is a multifactorial chronic ophthalmic disease. Its symptoms include blurry vision, foreign body sensation, pain, grittiness, ocular dryness and discomfort. Multiple studies have revealed that DED has a negative impact on patients’ quality of life, as well as their physical and mental health. In line with such findings, other research projects have indicated that depression, anxiety and stress share common risk factors associated with DED. Objective: We aimed to investigate the association between DED and depression, anxiety and stress among Saudi Arabian adults. Methods: This is a cross-sectional study conducted on 335 Saudi Arabian patients aimed to assess the prevalence of DED among individuals with depression, anxiety and stress. Data were collected using a self-administered questionnaire with the Depression Anxiety Stress Scales-21 (DASS-21) to assess the severity of stress, depression and anxiety, and the Ocular Surface Disease Index (OSDI) to assess DED symptoms. Results: The final number of participants was 448. Furthermore, 72.3% of them were aged 18 - 30 years, and 69.6% of them were females. The prevalence of depression, anxiety, and stress among patients with DED was 62.1%, 66.1%, 54%, and 77.9% respectively. Furthermore, we found that there were no significant differences between participants regarding the severity of DED based on different age groups (P = 0.889). Females with depression, anxiety, and stress, on the other hand, were significantly more likely to have severe DED than males with similar conditions. Conclusions: We confirmed a high prevalence of depression, anxiety, stress and DED in Saudi Arabian patients. There was a significant correlation between the four studied variables in which the greatest correlation was between anxiety and DED.

Type 2 diabetes (T2D) is common in the elderly and more than half of the people with diabetes are over 65 years old. Elderly diabetic patients have a higher frequency of hypertension, coronary artery disease and chronic kidney disease than non-diabetic elderly patients and the risk of these complications increases with patient age, duration of the diabetes and glycated hemoglobin values. Besides the known classical factors of renal disease progression, can one suppose that the age of onset of diabetes may also affect renal disease progression in elderly diabetic patients? The aim of this study was to determine clinical and biological parameters at admission and throughout evolution of elderly diabetic patients with T2D diagnosed before vs. after age 65 years.

As part of improving services done for various clients in all Moroccan areas, Moroccan exportation group of fruits and vegetables in collaboration with their packaging units and producers, tends to cooperate in order to face with international competitiveness. Indeed, the complexity of networks of partners has led policy-makers to implement new techniques and tools to help control different processes. For this reason, the implementation of a permanent monitoring of different operations ranging from production, packaging, and distribution of perishable products has become paramount. This article aims to propose a model of multi-agent citrus supply chain, based on indicators for monitoring and evaluation of performance of its logistics systems, in order to build a new independent, robust and responsive chain, and to optimize and control the flow of materials and information between the different actors and stakeholders of the chain.

Biodiesel was produced at small scale by transesterification of used frying oil(UFO) recovered from Moroccan pastry shops and fish frying restaurants. Biodiesel was first synthesised at laboratory scale in order to optimize the transesterification parameters. The cost of the final product was also optimized using low-cost raw *** UFO and the produced biodiesel were characterized with several techniques including gas chromatography,1H NMR,13 C NMR, FTIR, and TGA–TDA techniques.1H NMR gas chromatographic analyses of the final product confirmed that the transesterification in the chosen experimental conditions was completed. These results were confirmed by TGA–TDA analysis used as new techniques to monitoring triglyceride conversion. The biodiesel did not contain any trace of glycerol, and it did meet the international standards. The transesterification at low cost in small scale conditions was performed at 60 °C using 1.2% of KOH and a methanol/oil molar ratio of 6:1. A yield of 80.8% was achieved. The properties of the produced biodiesel were found to be as good as those of biodiesels obeying to European standards. The biodiesel production was also performed at small-scale for individual utilisation. Thus, the product was tested in a kerosene stove for heating and non-modified commercial diesel engine producing electricity.

A non invasive ultrasonic method is used to detect whether or not the frozen fish has suffered a partial or total accidental thawing. The time of flight and the peak to peak amplitude of the ultrasonic signals backscattered by fish are recorded during thawing. The comparison of the evolution curves and images corresponding to first and second thawing shows indicators of accidental thawing. The monitoring of thawing process showed that its assessment can be reduced to the measurement of the water content lost by fish. The attempt to replace the original water lost by fish in first thawing is analyzed. The influence of the transducer frequency on fish thawing evaluation is tested.
