    A februĂĄr 24-Ă©n kitört orosz−ukrĂĄn hĂĄborĂșban szĂĄmos olyan fegyvert is bevetettek, amelyrƑl korĂĄbban alig rendelkeztĂŒnk informĂĄciĂłval, sƑt mĂ©g a lĂ©tezĂ©sĂŒk sem biztos, hogy ismert volt. Ilyen eszköz a repĂŒlƑfedĂ©lzeti hiperszonikus rakĂ©ta, a H-47M2 „Kindzsal”. Ebben a publikĂĄciĂłban ezt az eszközt szeretnĂ©m bemutatni, kitĂ©rve a fejlesztĂ©s elƑzmĂ©nyeire is Ă©s magĂĄra a hiperszonikus sebessĂ©g elĂ©rĂ©sĂ©nek rövid törtĂ©netĂ©re, valamint a sajtĂłban megjelent cikkekre, amelyek szerint az ukrĂĄn hadsereg lelƑtt egy ilyen eszközt. In the Russian-Ukrainian war, that started on 24 February, a number of weapons were used that we had little information before, and even their existence was not known. One such weapon is the Kh-47M2 “Kinzhal” air-launched hypersonic missile. In my publication, I would like to introduce this device, including the history of its development and a brief history of the achievement of hypersonic speeds, as well as the articles in the press which claim that the Ukrainian army shot down such a device

    A szerzƑ a cikkben a H145M könnyƱ, többcĂ©lĂș helikopter fedĂ©lzeti fegyvereit mutatja be. A cikkel elindĂ­t egy több rĂ©szes sorozatot, melyekben a helikopter fegyverrendszereit mutatja be. Ebben a cikkben a nem-irĂĄnyĂ­thatĂł rakĂ©tarendszert ismerhetjĂŒk meg

    Why Does the Attack Helicopter Have More Survival Ability Than the Armed Utility Helicopter? = MiĂ©rt rendelkezik a tĂĄmadĂł helikopter nagyobb tĂșlĂ©lĂ©si kĂ©pessĂ©ggel, mint a felfegyverzett szĂĄllĂ­tĂł/többfeladatĂș helikopter?

    The author highlights the difference between attack and armed utility helicopters and supports this with professional arguments. He also presents the most common weapon systems of combat helicopters. Points out that an armed transport helicopter or multipurpose helicopter cannot substitute attack helicopters at all. A szerzƑ kiemeli a kĂŒlönbsĂ©get a harci Ă©s a felfegyverzett segĂ©dhelikopterek között, Ă©s ezt szakmai Ă©rvekkel tĂĄmasztja alĂĄ. Bemutatja a harci helikopterek leggyakoribb fegyverrendszerĂ©t is. RĂĄmutat, hogy egy felfegyverzett szĂĄllĂ­tĂłhelikopter vagy többcĂ©lĂș helikopter egyĂĄltalĂĄn nem helyettesĂ­theti a harci helikoptereket

    Genistein isoflavone glycoconjugates in sour cherry cultivars : Prunus cerasus L.

    Although the isoflavone genistein has well-established health-beneficial effects, it is not a major component of Western diet, since soy consumption, the main dietary source of genistein, is low in these populations. Genistein compounds were studied in twelve commercial sour cherry (Prunus cerasus L.) cultivars grown in Hungary. High performance liquid chromatography coupled to quadrupole/time-of-flight mass spectrometry, equipped with electrospray ion source (HPLC-ESI-qTOFMS) was used for screening and confirmatory analyses. Genistin and genistein were found in some Hungarian native sour cherry cultivars including ‘Pipacs1’, ‘Kántorjánosi’, ‘Debreceni bƑtermƑ’ and ‘Éva’. Genistein content in fruits of the latter three cultivars ranged between 0.4 to 0.6 mg, while in ‘Pipacs1’ a total of 4.4 mg genistein compounds (expressed as aglycone equivalents per 100 g of fresh fruit) was determined. These cultivars may play an important role as complementary genistein sources in the Western diet. Especially ‘Pipacs 1’, may be best utilized in functional food products
