    Apples contain substantial amounts of polyphenols, and diverse phenolics mainly flavonoids and phenolic acids, have been identified in their flesh and skins. This work aimed to analyze the overall landscape of the research literature published to date on apple phenolic compounds in the context of human and animal health. The Web of Science Core Collection electronic database was queried with (apple* polyphenol*) AND (health* OR illness* OR disease* OR medic* OR pharma*) to identify relevant papers covering these words and their derivatives in the titles, abstracts, and keywords. The resulted 890 papers were bibliometrically analyzed. The VOSviewer software was utilized to produce term maps that illustrate how the frequent phrases fared in terms of publication and citation data. The apple polyphenol papers received global contributions, particularly from China, Italy, the United States, Spain, and Germany. Examples of frequently mentioned chemicals/chemical classes are quercetin, anthocyanin, catechin, epicatechin, and flavonol, while examples of frequently mentioned medical conditions are cardiovascular disease, atherosclerosis, diabetes, Alzheimers disease, and obesity. The potential health benefits of apple polyphenols on humans and animals are diverse and warrant further study.Authors acknowledge the support from The National Centre for Research and Development (NCBR) of Poland (project number POIR.01.01.01-00-0593/18).info:eu-repo/semantics/publishedVersio

    The subject of this work is to show the significance of the shape of a chip during automated cutting process. Selected ways of the influence on a chip shape are going to be shown. The main point is the assistance of chip fracture by a compressed stream of cutting-tool lubricant. This mechanism is shown on the example of tool system CoroTurn HP. The results of preliminary researches are presented graphically.W pracy poruszono znaczenie postaci i kszta艂tu wi贸ra podczas obr贸bki w zautomatyzowanym - elastycznym systemie wytwarzania. Przedstawiono wybrane sposoby oddzia艂ywania na posta膰 wi贸ra. Szczeg贸lny nacisk po艂o偶ono na wspomaganie procesu 艂amania wi贸ra spr臋偶onym strumieniem p艂ynu obr贸bkowego. Na przyk艂adzie systemu narz臋dziowego CoroTurn HP om贸wiono budow臋 i spos贸b mechanizm 艂amania wi贸ra strumieniem spr臋偶onej cieczy obr贸bkowej. Wyniki wst臋pnych bada艅 rozpoznawczych przedstawiono w postaci graficznej

    W pracy przedstawiono proces generowania wirtualnego kontrolera VNC w aplikacji Post Builder systemu NX z uwzgl臋dnieniem typu sterowania maszyny. Skonfigurowano wykonany model kinematyczny wraz z kontrolerem i postprocesorem w bibliotece systemu NX. Przygotowano do obr贸bki przyk艂adowe modele przy wykorzystaniu Synchronous Technology oraz wykonano program obr贸bki. Przeprowadzono weryfikacj臋 艣cie偶ek i symulacj臋 obr贸bki. W ko艅cowej cz臋艣ci pracy por贸wnano zasymulowan膮 obr贸bk臋 z rzeczywistym procesem frezowania podczas pr贸b na maszynie.In this paper generating process of virtual controller is presented. This process is care out with used NX system with Post Builder application and take into type of steering machine system. Kinematics model with controller and postprocessor in NX library was configured. Machining process of geometrical models with used Synchronous Technology and NC program was developed. In this article tool path verification and simulation is presented. Finally, process of machining simulation and real cutting process during tests on CNC machine tool is compared
