It is necessary to use the means of recovery and other means that help to get rid of the effects of fatigue, as the game of badminton and the effectiveness of running 800 meters fall within the mixed system with the superiority of the anaerobic system by more than the air system, so requires the development of energy systems In proportion to the time of the match for badminton players and their travels and high performance and ability to tolerate the high level of lactic acid in the muscles and blood and increase the pain associated with the fatigue that occurs during the performance. In light of the physical and physiological processes of these actions N it should seek through training programs to develop your endurance and wind energy systems and anaerobic together to perform and withstand voltage during the race and increase muscle efficiency in carrying lactic acid, which helps to delay the onset of fatigue and achieve better achievement.Because of the experience of the two researchers in the field of sports there are several factors affecting training, including the use of training methods, as each method has its characteristics that distinguish from the other, has been conducted several studies on some of these methods, And the accumulation of lactic acid in the muscles and blood is one of the most important variables affecting the game of flying badminton and ran 800 meters, and relying on those variables make the coach and athlete in the area of safety, whether during training or race, so the researchers decided to Conduct a study NH quickly hospitalization according to pregnancy training for some physiological and biochemical variables of the players and hostile aircraft 800 badminton.The aim of the research is to identify the speed of hospitalization according to the training load of some physiological and biochemical variables of the badminton and air maxi 800m youth, to identify the differences in the speed of hospitalization between the badminton players and the 800m youth.Methodology: The research sample was chosen in a deliberate way from the players of the team of the badminton youth (5) players, and the players of the team for 800 m, the number of (5) player, the tests used in the search first: pulse rate, fatigue equation, measure the concentration of lactic acid in Blood test after blood pressure, oxygen saturation ratio, biochemical tests, RBC test, Hb test, PCV test, Ca test. Tests were conducted for the variables investigated after the end of the training program. Interpretation of results.The three researchers concluded: For badminton players, the preference for muscle fatigue tests and the measurement of lactic acid in the physiological indicators Hb, P.C.V within the biochemical indicators.The three researchers recommend: the need to emphasize training programs and hospitalization during the periods of public and private preparation and competitions.
The article presents the synthesis and liquid crystalline properties of some of new bent and linear core compounds containing a 1,3,4-oxadiazole, piperazine and thiazolidin-4-one rings as a central core. The new synthesized compounds were characterized by elemental analysis and FTIR, ¹HNMR and mass spectroscopy). The liquid crystalline properties were studied by polarized optical microscopy and differential scanning calorimetry. All Schiff bases compounds with 1,3,4-oxadiazole and piprzaine ring in central core presented liquid crystalline properties. The liquid crystallinity of compounds containing 1,3,4-oxadiazole and thiazolidin-4-one rings as a central core were found depending on the type of terminal substituents.
In this paper, we established a mathematical model of an SI1I2R epidemic disease with saturated incidence and general recovery functions of the first disease I1. Considering the basic reproduction number, we obtained conditions for both disease-free and co-existing cases. The equilibrium points local stability is verified by using the Routh-Hurwitz criterion, while for the global stability, we used a suitable Lyapunov function to analyze the endemic spread of the positive equilibrium point. Moreover, we carried out the local bifurcation around both equilibrium points (disease-free and co-existing), where we obtained that the disease-free equilibrium point undergoes a transcritical bifurcation. We conduct numerical simulations that suppo

A new series of schiff base and aminothiadiazole derivatives of N- substituted phthalimide (I-VI) were synthesized. In this work, the intermediate 4-(1,3-dioxoisoindolin-2-yl)benzaldehyde compound (I), was formed by reaction of 4-amino benzaldehyde with phthalic anhydride in glacial acetic acid(GAA). A series of Schiff bases (IV-VI) was prepared by the reaction of benzidine with compound (I) in ethanol and presence of GAA as a catalyst to form compound (IV) which react with compound (I) and p-nitro benzyldehyde to give compound (V) and (VI) respectively. A new phthalimide thiosemi-carbazone derivative (ll) was prepared by reaction of compound (l) with thiosemi-carbazide HCl in the presence of equimolar amount of sodium acetate. Fina

4-chloro and 4- nitro substituted phenol and aniline incorporated to a carboxylic group of naproxen a well-known non-steroidal anti-inflammatory drug (NSAID) to increase bulkiness were synthesized for evaluation as a potential anti-inflammatory agents with expected COX-2 selectivity. In vivo acute anti-inflammatory activity of these compounds (I-IV) was evaluated in rats using egg-white induced edema model of inflammation in a dose equivalent to (2.5 mg/Kg) of naproxen. All tested compounds produced a significant reduction in paw edema with respect to the effect of propylene glycol 50% v/v (control group). Moreover, compounds I and IV might show higher effect comparable to that of naproxen and to that of compounds II & III whic
