The Effect Of Active Warm -Up Exercises On Flexibility And Achievement Among Effectiveness High Jump Players

Flexibility is one of the elements of fitness that contributes to others, such as strength, speed, and endurance in building and developing the motor performance of the player. Also, mathematical forms need this important element. And the athlete, which has good flexibility, will help him to use the rest of the other fitness elements with a little effort and a short time to improve the achievement and its development. Also, the weak flexibility in the player leads to a weak level of sports achievement. Exaggeration in the flexibility of the joints leads to its relaxation and sometimes it reaches the state of infection, and exaggeration in it affects a harmful effect on strength. So it is necessary to pay attention when training to develop it. It is considered an important basic element among the jumping in the effectiveness of high jumping, as the player must have the flexibility of all joints in order to be able to reach a good result as well as active specialized warmth. The researchers used the experimental curriculum to suit the nature of the research. The research sample was from Al -Qurna Sports Club for Higher Jump in Basra Governorate. The tests for flexibility and achievement were applied to the high jump. Tribal tests and post -tests for the research sample, extracting results and processing them statistically, were the most important recommendations: -The necessity of paying attention to flexibility in choosing the appropriate exercises in the training curricula in jumping activities, especially high jumping in the atmosphere to achieve good achievement. The necessity of paying attention to the varied active and corresponding warm -up with the nature of the performanc

Synthesis and Investigation of Metals Oxide Pastes Used as Semiconductors Electrode for Dye-sensitized Solar Cells

The aim of this research is to prepare some of metal oxides pastes to be used as semi-conductors electrode to manufacture of solar cells devices (third generation). The efficiency of these cells were tested by using these pastes to determine the response and susceptibility of these pastes for adsorbing of photosensitive pigments on their surfaces and pores, Three types of metal oxides such as Titanium oxide, Zinc oxide and Aluminium oxide, were prepared in this research. These pastes were identified by measuring UV-visible spectra and also by microscope instrument. The experiments which have been demonstrated approved the susceptibility and adsorption of these pastes to the photosensitive dyes on their surface and gave conversion efficiency up to 1.64%. In this research, a comparison was made between the pastes that were prepared in laboratory and the imported commercial paste in terms of efficiency.</jats:p

Pancreatic surgery outcomes: multicentre prospective snapshot study in 67 countries

Background: Pancreatic surgery remains associated with high morbidity rates. Although postoperative mortality appears to have improved with specialization, the outcomes reported in the literature reflect the activity of highly specialized centres. The aim of this study was to evaluate the outcomes following pancreatic surgery worldwide. Methods: This was an international, prospective, multicentre, cross-sectional snapshot study of consecutive patients undergoing pancreatic operations worldwide in a 3-month interval in 2021. The primary outcome was postoperative mortality within 90 days of surgery. Multivariable logistic regression was used to explore relationships with Human Development Index (HDI) and other parameters. Results: A total of 4223 patients from 67 countries were analysed. A complication of any severity was detected in 68.7 per cent of patients (2901 of 4223). Major complication rates (Clavien–Dindo grade at least IIIa) were 24, 18, and 27 per cent, and mortality rates were 10, 5, and 5 per cent in low-to-middle-, high-, and very high-HDI countries respectively. The 90-day postoperative mortality rate was 5.4 per cent (229 of 4223) overall, but was significantly higher in the low-to-middle-HDI group (adjusted OR 2.88, 95 per cent c.i. 1.80 to 4.48). The overall failure-to-rescue rate was 21 per cent; however, it was 41 per cent in low-to-middle- compared with 19 per cent in very high-HDI countries. Conclusion: Excess mortality in low-to-middle-HDI countries could be attributable to failure to rescue of patients from severe complications. The authors call for a collaborative response from international and regional associations of pancreatic surgeons to address management related to death from postoperative complications to tackle the global disparities in the outcomes of pancreatic surgery (NCT04652271; ISRCTN95140761)
