CALCULATED CALORIES FOR TRAINING AND THEIR EFFECT ON DEVELOPING SOME PHYSICAL AND BIOMECHANICAL ABILITIES AND ACHIEVING 400-METER RUN FOR YOUTH

The research problem arose through researchers' follow-up of training curricula for athletes in athletics in general and 400-meter runners in particular. Most training curricula adopt physical and skill exercises without paying attention to the need for energy appropriate for the effort exerted during the race or training. The Pro Health program - Commerce with Compassion is used in this research to calculate the calories spent during training to find out what is burned during training. The experimental research method is used in this research. The research sample was selected from young 400-meter joggers (9 runners). The arithmetic mean for age is (19.64), a standard deviation is (± 1.5), with an arithmetic mean for training age which is (6.6) with a standard deviation (± 1.65), an arithmetic mean for mass (71) with a standard deviation (± 2.54), an arithmetic mean for height (172) cm, and a standard deviation (± 3.5). The results showed that the calories consumed during training changed during training. The differences were statistically in favor of the post-test. The differences energy variable remaining in the body after performing the effort, whether in calories or kilojoules, were not significant. This means that the amounts of energy remained the same, whether in the pre or post-test. The cost of energy per 1 kg of the body, appeared in the indicator, indicated that the differences are not significant between what the body consumes during physical activity and the remaining calories in the body for both tests. It also showed that there is an imbalance between calories and their output in kilo joules that the sample members take from food, and the calories they burn to make physical effort.

Concrete Beams Strengthened with Jute Fibers

Nowadays, the reinforcement of concrete with natural fibers can consider being an effectual scheme to achieve the global demand for sustainable development. Due to sustainability, bio degradability, and environmental friendly, natural fibers are preferred as compared to synthetic fibers. The present study investigated the effect of width and thickness of jute fiber strips on the mechanical properties of reinforced concrete beams (RC beams). The experimental program consisted testing of twenty-four RC beams (150*150*1000 mm) comprised of four groups. The first group consisted of three reference RC beams, the second group consisted of three RC beams strengthened longitudinally with carbon fiber strip (CFRP) of 15 cm width, the third group included nine RC beams strengthened longitudinally with one layer of jute fiber strips (JFRP) having variable width, 5, 10, and 15 cm, and lastly the fourth group which was same as the third group except using double layer of jute fiber strips. Generally, the results showed that toughness, ultimate flexural strength, and load carrying capacity of RC beams strengthened with JFRP were increased with the increase of the strip width and thickness. On the other hand, ductility and stiffness were decreased with the increase of the strip width. Test results showed that load carrying capacity was improved by 5.56 and 11.1% for one layer of jute fiber strips of 5 and 15 cm width respectively as compared with the reference specimens. On the other hand, the load carrying capacity was improved by 3.95 and 8.75 % for two layers of jute fiber strips of 10 and 15 cm width respectively as compared with the one layer strengthened specimens. Concerning the CFRP strengthening, the load carrying capacity was improved by 77.76% as compared with the reference specimens.

An improved approach for medical image fusion using sparse representation and Siamese convolutional neural network

Multimodal image fusion is a contemporary branch of medical imaging that aims to increase the accuracy of clinical diagnosis of the disease stage development. The fusion of different image modalities can be a viable medical imaging approach. It combines the best features to produce a composite image with higher quality than its predecessors and can significantly improve medical diagnosis. Recently, sparse representation (SR) and Siamese Convolutional Neural Network (SCNN) methods have been introduced independently for image fusion. However, some of the results from these approaches have recorded defects, such as edge blur, less visibility, and blocking artifacts. To remedy these deficiencies, in this paper, a smart blending approach based on a combination of SR and SCNN is introduced for image fusion, which comprises three steps as follows. Firstly, entire source images are fed into the classical orthogonal matching pursuit (OMP), where the SR-fused image is obtained using the max-rule that aims to improve pixel localization. Secondly, a novel scheme of SCNN-based K-SVD dictionary learning is re-employed for each source image. The method has shown good non-linearity behavior, contributing to increasing the fused output's sparsity characteristics and demonstrating better extraction and transfer of image details to the output fused image. Lastly, the fusion rule step employs a linear combination between steps 1 and 2 to obtain the final fused image. The results depict that the proposed method is advantageous, compared to other previous methods, notably by suppressing the artifacts produced by the traditional SR and SCNN model

Sustained release of captopril from matrix tablet using methylcellulose in a new derivative form

The present study was aimed to evaluate the suitability of a newly synthesized polymer methylcellulose glutarate (MCG) for sustained release matrix system using antihypertensive drug captopril. Methylcellulose glutarate was first prepared using methylcellulose and glutaric anhydride with 1:0.5 ratio and confirmed with FTIR, NMR and MALDI. MCG was then employed in various amounts with fixed amount of captopril for the preparation of matrix tablets. Decreasing the amount of MCG had no considerable sustaining effect on in vitro drug release from the matrix system. MCG was also evaluated at different pH values and stirring speed and no appreciable difference in the release profiles was noticed. Moreover, dissolution data of optimum formulation followed zero-order kineticColegio de Farmacéuticos de la Provincia de Buenos Aire

This paper presents the development of a smart plug with a wireless Zigbee sensor for measuring power consumption of electrical appliances in the HEMS. Experiments were carried out to evaluate the power consumption of a wireless sensor node in a smart plug using only Zigbee as a microcontroller. Experimental results showed that the smart plug using Zigbee is capable of processing and analyzing the analogue sensor signal with lower power consumption. In addition, the data obtained from the wireless sensor is more accurate and smoother as compared with the data obtained from the oscilloscope. The proposed smart plug has the characteristics of simple design, low cost, low power consumption and easy to control electrical home appliances by switching on/off from the HEMS controller

Laparoscopy in management of appendicitis in high-, middle-, and low-income countries: a multicenter, prospective, cohort study.

BACKGROUND: Appendicitis is the most common abdominal surgical emergency worldwide. Differences between high- and low-income settings in the availability of laparoscopic appendectomy, alternative management choices, and outcomes are poorly described. The aim was to identify variation in surgical management and outcomes of appendicitis within low-, middle-, and high-Human Development Index (HDI) countries worldwide. METHODS: This is a multicenter, international prospective cohort study. Consecutive sampling of patients undergoing emergency appendectomy over 6 months was conducted. Follow-up lasted 30 days. RESULTS: 4546 patients from 52 countries underwent appendectomy (2499 high-, 1540 middle-, and 507 low-HDI groups). Surgical site infection (SSI) rates were higher in low-HDI (OR 2.57, 95% CI 1.33-4.99, p = 0.005) but not middle-HDI countries (OR 1.38, 95% CI 0.76-2.52, p = 0.291), compared with high-HDI countries after adjustment. A laparoscopic approach was common in high-HDI countries (1693/2499, 67.7%), but infrequent in low-HDI (41/507, 8.1%) and middle-HDI (132/1540, 8.6%) groups. After accounting for case-mix, laparoscopy was still associated with fewer overall complications (OR 0.55, 95% CI 0.42-0.71, p < 0.001) and SSIs (OR 0.22, 95% CI 0.14-0.33, p < 0.001). In propensity-score matched groups within low-/middle-HDI countries, laparoscopy was still associated with fewer overall complications (OR 0.23 95% CI 0.11-0.44) and SSI (OR 0.21 95% CI 0.09-0.45). CONCLUSION: A laparoscopic approach is associated with better outcomes and availability appears to differ by country HDI. Despite the profound clinical, operational, and financial barriers to its widespread introduction, laparoscopy could significantly improve outcomes for patients in low-resource environments.
