The International Canoe Federation includes 10 forms of kayaking and canoeing and recognizes 4 additional disciplines. One of the most popular is canoe polo. Canoe polo is a team sport that belongs ...to the family of sports games. Two teams of five players each fight to score more goals, with a water polo ball, in a pool of specific dimensions. Canoe polo developed in parallel in three similar variants of the rules, as an alternative to paddling during windy and cold winter days. Canoe polo contains the largest number of different techniques in relation to all paddling sports, while ball handling is done with a mixture of water polo, handball, basketball, and volleyball techniques. Simultaneous handling of the ball, with an overview of the game and interfering with the opponent is a very demanding coordination activity that does not exist in paddling in nature with different obstacles, both in terms of content and dynamics. Today, canoe polo is played in about 40 countries. Wild and flat water kayak and canoe disciplines have existed in the countries of the Western Balkans outside the European Union for many years, while canoe polo activities, clubs and competitions do not exist at all. The introduction of canoe polo in the sports systems of the West Balkan countries outside of European Union can be used as a means to popularize canoeing, as well as to raise the quality of canoeists by applying situational and super-situational training methods. Very demanding activities during more diverting trainings, with a greater opportunity to compete, as well as with a longer and more meaningful competition calendar, can significantly improve the skills needed for kayaking and canoeing in all its manifestations. In addition, the economic effect of development through sports facilities, infrastructure and boats with protective equipment should not be neglected, which at some point may become the basis for the organization of domestic and international competitions.
Internacionalna Kanu Federacija prepoznaje 9 pojavnih oblika kanua. Jedna od veoma popularnih je kanu polo. Kanu polo je timski sport koji pripada porodici sportskih igara. Dva tima sa po pet igrača ...se međusobno bore da postignu veći broj golova sa vaterpolo loptom, u bazenu specifičnih dimenzija. Kanu polo se razvijao paralelno u tri slične varijante pravila i to kao alternativa veslanja za vreme vetrovitih i hladnih zimskih dana. Kanu polo sadrži najveći broj različitih tehnika u odnosu na sve veslačke sportove, dok se baratanje loptom vrši mešavinom vaterpolo, rukometnih, košarkaških i odbojkaških tehnika. Simultano rukovanje loptom, uz pregled igre i ometanje protivnika je veoma zahtevna koordinaciona aktivnost koja prevazilazi veslanje u prirodi sa različitim preprekama, kako po sadržaju tako i po dinamici. Danas se kanu polo igra u oko 40 država. Divljevodaške kanu discipline u državama zapadnog Balkana nisu razvijene na visokom nivou, dok kanu polo aktivnosti, klubovi i takmičenja uopšte ne postoje. Uvođenje kanu poloa u sistem sporta zapadno balkanskih država može biti iskorišćeno kao sredstvo za omasovljenje kajakaškog sporta, kao i za podizanje kvaliteta kajakaša primenom situacionog i nadsituacionog metoda vežbanja. Veoma zahtevne aktivnosti na različitijim treninzima, sa većom mogućnošću za takmičenje, kao i sa dužim i sadržajnijim takmičarskim kalendarom, mogu značajno unaprediti veštine potrebne za veslanje u kajaku i kanuu u svim njegovim pojavnim oblicima. Pored toga ne treba zanemariti ni ekonomski efekat razvoja kroz sportske objekte, infrastrukturu i čamce sa zaštitnom opremom, koji u jednom trenutku mogu postati osnov za organizaciju domaćih i međunarodnih takmičenja.
Modern diagnostics in rowing enables more and more possibilities for recording, and comparing numerous stroke variables. At the same time, many coaches fall into the trap of strict respect for the ...prescribed norms, ratios, and temporarily results, which the athlete must achieve if he wants to stay in the world of competitive rowing. On the example of the comparison of rowing schools RC "Danubius" and RC "Partizan", descriptive indicators are on the side of RC "Danubius" at a time of 2000m, average force and average power. No significant differences were found in average force (sig = 0,167) between rowers of RC "Danubius" and RC "Partizan", while statistically significant differences were recorded in time at 2000m (sig = 0,036) and power (sig = 0,02) in favor of rowers of RC “Danubius”. On the other hand, a higher correlation of average force (-0,955) and power (-0,928) with time on 2000m was achieved by RC "Partizan" than RC "Danubius" (-0,931) and (-0,896). The correlation between the average force, and the average power within one team shows a higher correlation for RC “Partizan" (0,95) compared to RC "Danubius" (0,755). The obtained results are not enough for single rower or crew elimination from competition to recreational section in the process of too frequent and strict selection of rowers, considering different possible ways of building rowing techniques and numerous parasitic factors that may affect measured variables, specialy at the age under 14 and novice rowers in general.
Savremena dijagnostika u veslanju omogućava sve više mogućnosti za beleženje i poređenje brojnih varijabli zaveslaja. Pri tom mnogi treneri padaju u zamke strogog poštovanja propisanih normi, odnosa ...i prolaznih rezultata, koje sportista mora ostvariti ukoliko želi da ostane u svetu takmičarskog veslanja. Na primeru poređenja veslačkih škola VK “Danubiusa” i VK “Partizan”, deskriptivni pokazatelji su na strani VK “Danubius” kod vremena na 2000m, prosečne sile i prosečne snage. Prosečna sila, ne beleži značajnost razlika između veslača VK “Danubius” i VK “Partizan” (sig=0,167), dok su zabeležene statistički značajne razlike kod vremena na 2000m (sig=0,036) i snage (sig=0,02) u korist veslača VK Danubiusa”. S druge strane veću korelaciju prosečne sile (-0,955) i snage (-0,928) sa vremenom na 2000m ostvarili su veslači VK “Partizan” od veslača VK “Danubius” (-0,931) i (-0,896). Korelacija između prosečne sile i prosečne snage unutar jedne ekipe pokazuje veću korelaciju kod veslača VK “Partizan” (0,95) u odnosu na veslače VK “Danubius” (0,755). Dobijeni rezultati nisu dovoljni da se jedna od ekipa ili pojedini veslač u nekom sličnom poređenju izbaci iz takmičarskog pogona u procesu previše čestih i strogih selekcija veslača, obzirom na različite moguće puteve izgradnje veslačke tehnike i brojnih parazitarnih faktora, koji na navedene varijable mogu uticati, posebno u uzrastu pionira i veslača početnika uopšte.
Severe form of haemophilia in women is an extremely rare condition. Owing to the rarity of the disease there are no precise recommendations concerning the optimal management of pregnancy and delivery ...in these patients. We are reporting the clinical course and management of a 30-year-old woman with a severe form of haemophilia A (factor VIII <1 IU/dl) during her first pregnancy and delivery. Antepartum, she was treated on demand by FVIII concentrate and she delivered at 37 weeks of gestation by cesarean section. In postpartal period an excellent control of bleeding was obtained by regularly administering FVIII concentrate for several days as well by concomitant use of tranexamic acid and oral contraceptive pills in the next 6 weeks.
Eleven children with war-related peripheral nerve injury and 16 children with accident-related nerve injury between the ages of 3 and 15 years were assessed clinically and electromyoneurographically ...for 1-15 months. Lesions of 32 peripheral nerves were registered in children with war injuries. Children with accidentally acquired injuries had lesions of 27 peripheral nerves. A complete loss of voluntary motor unit potentials and signs of total axonal damage were recorded in the upper arms of seven of 11 children with war injuries and in five of 16 children with accidental injuries. There was a diminished number of motor unit potentials and a reduction in compound muscle action potential amplitudes, indicating partial nerve lesions, in 11 of 16 children with accidental injuries (mostly after humeral fracture) and in three of 11 children with brachial plexus war injuries. Reinnervation signs first occurred after 5-9 months (mean = 6.2 months) in war-injured children receiving conservative treatment and after 2-7 months (mean = 3.4 months) in children with accidentally acquired injuries. War-related peripheral nerve injuries in children are more frequently associated with complete denervation followed by slower or delayed nerve regeneration. In children with accidentally acquired nerve injuries the course is significantly better.
The paper focuses on the project of replacement of district heating plant (HP Doboj) with the so-called combined cycles of simultaneous production (co-generation) of useful mechanical operations, ...i.e. electric energy on the one hand and heat energy on the other hand in heat and power plants (CHP Doboj). This would enable saving of primary energy in comparison to separated production of heat and electricity. This would also help increase its operation time and at the same time its buildings would undergo necessary refurbishment. The economic-financial evaluation of the project of CHP Doboj shows that there are relevant economic parameters for further elaboration and continuation with high processing level designs. The evaluation did not take into account the expected benefits related to the generation of combined production, i.e. higher energy efficiency conpared to that produced by the present condensation thermal plants in Bosnia and Herzegovina. Combined plants certainly represent one of the factors of sustainable development, but they also imply provision of certain incentives from both the state and the European banking systems.
