Critical evaluation of numerical techniques for highly non-linear field diffusion modelling
No full textVarious numerical techniques have been applied to multidimensional field diffusion problems with front-type behaviour, moving boundaries and non-linear material properties. Advantages and implementation challenges of the methods are discussed with special attention paid to conservation properties of the algorithm and achieving accurate solutions close to the moving boundaries. The techniques are evaluated using analytical solutions of diffusion problems with cylindrical symmetry
Late Miocene Turtles of Grytsiv (western Ukraine) with Rodent Gnaw Marks on the Carapace Surface
Get PDFThe paper describes a series of turtle remains from the Early Late Miocene of Grytsiv (Khmelnytskyi Oblast, Ukraine). This fossil assemblage was quite diverse and included representatives of four families (Emydidae, Geoemydidae, Testudinidae, and Trionychidae), most of which are described only to the family level due to incompleteness. The discovery of shell fragments, identified here as Testudo chernovi, is the earliest record of this species on the territory of Ukraine. Scratches on the nuchal of T. chernovi are interpreted as traces of gnawing or rasping and are described as a new ichnospecies, Machichnus inrosus isp. n. These traces are identified as gnawing marks of the rodent Anomalomys grytsivensis, as evidenced by the width of the lower incisors and the presence of two characteristic longitudinal ridges on their labial surface

Ensuring high high-precision testing of implants in the regulation of intra intra-eye pressure
No full textAmong the diseases that lead to partial or complete loss of visual function is glaucoma, which is characterized by increased intraocular pressure (IOP) due to changes in the structures of the eye and the human body, which inevitably leads to blindness. According to the WHO in 2020. more than 5 million people suffer from vision loss in glaucoma, which accounts for 13.5% of all cases of blindness in the world. Today this figure in Ukraine reaches more than 200 thousand patients. Visual problems significantly reduce the level of information perception and cause a pathological condition with progressive death of ganglion cell axons, which causes a decrease and complete loss of the visual field. Known methods of glaucoma treatment use drug therapy, laser therapy and surgical implantation of drainage devices. It was found that the main cause of the disease is a decrease in the speed of movement and outflow of intraocular fluid through the trabecular system of the eye, due to a significant increase in pressure. The optimal rate of fluid formation is normally 2-2.5 μl / min., Ie during the day through this natural system of the patient should be released in a controlled manner and about 3 ml. It is obvious that the implantation of drainage devices in glaucoma is performed after previous unsuccessful treatment procedures and is the last chance to preserve the patientʼs vision, provided that the rate of fluid leakage is successfully regulated. Therefore, there is often a need for preoperative individual selection of implants with the necessary parameters

Late Pleistocene Birds from Binagada (Azerbaijan) in Collection of the National Museum of Natural History (Kyiv, Ukraine)
No full textAbstract
Bird fossils from the Late Pleistocene locality Binagada, deposited kept in the National Museum of Natural History in Kyiv (Ukraine), are described in this paper. Twenty six bird species are identified, including five (Little Stint, Great snipe, Jack snipe, White-winged lark and Rosy Starling) which have not been previously known from this locality. The validity of extinct species Calidris binagadensis (Serebrovsky, 1940) is confirmed and the invalidity of subspecies Anas platyrhynchos paleoboschas Serebrovsky, 1940 is shown. The finding of Rosy Starling fossils in Transcaucasian region confirms the range reduction of this species at the end of Pleistocene.</jats:p
Чисельність та просторовий розподіл сичика-горобця, Glaucidium passerinum (Strigiformes, Strigidae), у Рівненському природному заповіднику (Україна)
No full textThe breeding status and abundance of the Eurasian pygmy owl Glaucidium passerinum (Linnaeus, 1758) in Rivnenskyi Nature Reserve was estimated based on results of field research conducted in 2013 to 2018. We suggest the nesting of 9 to 12 pairs of the Eurasian pygmy owl in the territory of the Reserve, in particular 7 to 10 pairs in Perebrody site, 1 or 2 pairs in Somyne site and a single pair in Syra Pohonia site. The Eurasian pygmy owl has diurnal activity, which facilitates the species’ identification during field studies. It was noted that the voice activity of the tawny owl (Strix aluco), the great grey owl (Strix nebulosa) and the northern goshawk (Accipiter gentilis) leads to the termination of the pygmy owl’s vocalization.Установлен современный гнездовой статус и численность воробьиного сыча, Glaucidium passerinum (Linnaeus, 1758), на территории Ровенского природного заповедника по результатам полевых исследований 2013–2018 гг. Сделано предположение о гнездовании 9–12 пар воробьиного сыча на территории массивов заповедника (7–10 пар в массиве Переброды; 1–2 пар — Сомыне, одна пара на массиве Сырая Погоня). Воробьиный сыч на территории исследования проявляет дневную активность, чем облегчает полевые работы по его идентификации. Отмечено, что на прекращение вокализации воробьиного сыча влияет активизация токования серой неясыти (Strix aluco Linnaeus, 1758), бородатой неясыти (Strix nebulosa Johann Reinhold Forster, 1772) и ястреба-тетеревятника (Accipiter gentilis Linnaeus, 1758).Встановлено сучасний гніздовий статус та чисельність сичика-горобця, Glaucidium passerinum (Linnaeus, 1758), на території Рівненського природного заповідника за результатами польових обстежень 2013–2018 рр. Припускається гніздування 9–12 пар сичика-горобця на масивах заповідника (7–10 пар на масиві Переброди; 1–2 пар — Сомине, одна пара на масиві Сира Погоня). Сичик-горобець на території дослідження проявляє денну активність, що полегшує польові роботи по його ідентифікації. Відмічено, що на припинення вокалізації сичика-горобця впливає активізація токування сови сірої (Strix aluco Linnaeus, 1758), бородатої (Strix nebulosa Johann Reinhold Forster, 1772) та яструба великого (Accipiter gentilis Linnaeus, 1758).We would like to thank to our colleagues V. Ilchuk, R. Zhuravchak, O. Dobrynskyi, S. Churylovych, I. Tarhonskyi, O. Kybukevych, P. Hryniuk, and T. Kryvulskyi for participation in owl censuses in different times. The equipment used during field research was the courtesy of Idea Wild organization. We also thank to Z. Barkaszi for translating and editing of the manuscript
O desacoplamento par-impar do campo de pressão e algoritmos para simulação de descoamentos incompressiveis por volumes finitos
Get PDFDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro TecnologicoAlgumas técnicas para evitar o problema do desacoplamento par-ímpar campo de pressão (também conhecido como campo de pressão do tipo tabuleiro de xadrez) na simulação numérica de escoamentos incompressíveis são discutidas e testadas. Essas técnicas são testadas em associação com algoritmos utilizados em Volumes Finitos para a simulação desse tipo de escoamento. Comparações do desempenho dos códigos implementados são mostradas. A eficácia das diversas técnicas é verificada na simulação de escoamentos bidimensionais laminares
