    Get PDF
    Today proper names are studied by linguists, geographers, historians, ethnographers, culturologists, lingvistic study of the country experts, literary critics. The toponymy helps to restore lines of the historical past, to define moving borders, to outline areas of former distribution of languages. The increasing attention is paid to the description of a toponymic picture of certain regions, in this case Scotland. In this regard, there is a problem of development of a technique of introduction of regional approach to studying of toponymics. Thesaurus approach is the important direction of system studying of toponyms. Classification of macrotoponyms and microtoponyms, classification of toponymic nicknames and figurative names, classifications according to a structural-grammatical, morphological principle are presented in the article

    The first example of the reaction of 5-nitro-8-hydroxyquinoline as a C-nucleophile with quinazoline is described. As a result of the reaction of C, C-coupling, a stable Οƒ-adduct containing the drug nitroxalin on a heterocyclic carrier was obtained. The structure of the resulting adduct was confirmed by 2D 1H-13C HSQC, 1H-13C HMBC, and 1H-15N HMBC spectra

    Gradients of Taxonomic Diversity among Local Floras in the Russian Arctic

    Get PDF
    Latitudinal and longitudinal changes in taxonomic variables were analyzed in 319 local floras in the Russian Arctic. Within the studied segment of latitudinal gradient, most changes can be described in terms of linear regression with negative coefficients (a number of species, genera and families), or positive coefficients (a proportion of the leading families and genera). However, the mean number of species in a family or genus almost does not change with increasing latitude, although it slightly increases as one moves eastward. The proportion of monocots does not correlate with latitude, but slightly decreases as one moves eastward. Proportions of various families change asynchronously. Although correlation with longitude was less pronounced, mean species richness was specific to many subprovinces, even within a certain subzone. These differences reflect both the diversity of landscapes and the history of flora formation. Keywords: the Arctic, local floras, latitudinal and longitudinal gradient, floristic subprovince

    The results of a laboratory examination of 520 children aged 1β€”3 years are presented. The examination was conducted to determine the DNA of cytomegalovirus in children with acute cytomegalovirus infection in various biological media by polymerase chain reaction. The differences in the virus sheddingΒ  into the blood, saliva, and urine are established: the median of the viral load for saliva is 4.9 lg copies of DNA/ml, the blood 3.4 lg copies of DNA/ml, urine β€” 3.85 lg copies of DNA/ml. The cut of extreme values of the viral load are determined with the help of mathematical modeling which determine the clinical probability of developing acute CMV infection which allows for more accurate and timely assignment of etiotropic therapy.ΠŸΡ€Π΅Π΄ΡΡ‚Π°Π²Π»Π΅Π½Ρ‹ Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½ΠΎΠ³ΠΎ обслСдования 520 Π΄Π΅Ρ‚Π΅ΠΉ Π² возрастС 1β€”3 Π»Π΅Ρ‚.

    The aim. of the study is to optimize the Iaboratory diagnosis of cytomegaIovirus infection in chiIdren by finding cIinicaI and Iaboratory predictors corresponding to the acute stage of infection.MateriaIs and methods. The resuIts of 65 chiIdren age from 1 to 3 years outpatient of with cytomegaIovirus mono-nucIeosis are presented. Markers of herpes virus infections (CMV, EBV, HHV-6 type) were determined by PCR-reaI time (bIood, saIiva) and seroIogicaIIy (IgM, IgG).ResuIts. It has been estabIished. that acute cytomegaIovirus infection can occur both, in the form of infectious mononu-cIeosis and. be atypicaI accompanied, by proIonged fever and. severe Iymphadenopathy in most cases. Indirect Iaboratory markers of acute cytomegaIovirus infection are neutropenia and. hypoimmunogIobuIinemia IgA and. IgG. Acute cytomeg-aIovirus infection is accompanied by the virus shedding in both bIood and saIiva in aImost aII patients and the median vaIues of the viraI Ioad are different: 3,9 Ig DNA copies / mI for bIood, 4,9 Ig DNA copies / ml for saIiva. Using mathemati-caI modeIing, the β€œcut off" vaIue of viraI Ioad. for saIiva was determined, to be 4,1 Ig DNA copies / mI corresponding to 65.0% of the probabiIity of deveIoping acute CMV infection.ConcIusion. The study made it possibIe to substantiate the aIgorithm. for diagnosing acute cytomegaIovirus infection. in young chiIdren which. incIudes the most significant cIinicaI Iaboratory predictors, as weII as the caIcuIated. β€œcut off" vaIue of viraI Ioad. for saIiva equaI to 4,1 Ig DNA copies / mI. Determining the viraI Ioad in the saIiva of patients can be used, as an additionaI diagnostic criterion for the atypicaI form of acute cytomegaIovirus infection.ЦСль: ΠΎΠΏΡ‚ΠΈΠΌΠΈΠ·ΠΈΡ€ΠΎΠ²Π°Ρ‚ΡŒ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½ΡƒΡŽ диагностику цитомСгаловирусной ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ Ρƒ Π΄Π΅Ρ‚Π΅ΠΉ ΠΏΡƒΡ‚Π΅ΠΌ, опрСдСлСния клиничСских ΠΈ Π»Π°Π±ΠΎΡ€Π°Ρ‚ΠΎΡ€Π½Ρ‹Ρ… ΠΏΡ€Π΅Π΄ΠΈΠΊΡ‚ΠΎΡ€ΠΎΠ², ΡΠΎΠΎΡ‚Π²Π΅Ρ‚ΡΡ‚Π²ΡƒΡŽΡ‰ΠΈΡ… острой стадии ΠΈΠ½Ρ„Π΅ΠΊΡ†ΠΈΠΈ.ΠœΠ°Ρ‚Π΅Ρ€ΠΈΠ°Π»Ρ‹ ΠΈ ΠΌΠ΅Ρ‚ΠΎΠ΄Ρ‹: прСдставлСны, Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Ρ‹, Π°ΠΌΠ±ΡƒΠ»Π°Ρ‚ΠΎΡ€Π½ΠΎΠ³ΠΎ наблюдСния 65 Π΄Π΅Ρ‚Π΅ΠΉ с Ρ†ΠΈΡ‚ΠΎΠΌΠ΅Π³Π°Π»ΠΎΠ²ΠΈ-русным ΠΌΠΎΠ½ΠΎΠ½ΡƒΠΊΠ»Π΅ΠΎΠ·ΠΎΠΌ.

    The absolute abundance calibration project: the <i>Lycopodium</i> marker-grain method put to the test

    Get PDF
    Traditionally, dinoflagellate cyst concentrations are calculated by adding an exotic marker or β€œspike” (such as Lycopodium clavatum) to each sample following the method of Stockmarr (1971). According to Maher (1981), the total error is controlled mainly by the error on the count of Lycopodium clavatum spores. In general, the more L. clavatum spores counted, the lower the error. A dinocyst / L. clavatum spore ratio of ~2 will give optimal results in terms of precision and time spent on a sample. It has also been proven that the use of the aliquot method yields comparable results to the marker-grain method (de Vernal et al., 1987). Critical evaluation of the effect of different laboratory procedures on the marker grain concentration in each sample has never been executed. Although, it has been reported that different processing methods (e.g. ultrasonication, oxidizing, etc.) are to a certain extent damaging to microfossils (e.g. Hodgkinson, 1991), it is not clear how this is translated into concentration calculations. It is wellknown from the literature that concentration calculations of dinoflagellate cysts from different laboratories are hard to resolve into a consistent picture. The aim of this study is to remove these inconsistencies and to make recommendations for the use of a standardized methodology. Sediment surface samples from four different localities (North Sea, Celtic Sea, NW Africa and Benguela) were macerated in different laboratories each using its own palynological maceration technique. A fixed amount of Lycopodium clavatum tablets was added to each sample. The uses of different preparation methodologies (sieving, ultrasonicating, oxidizing …) are compared using both concentrations – calculated from Lycopodium tablets - and relative abundances (more destructive methods will increase the amount of resistant taxa). Additionally, this study focuses on some important taxonomic issues, since obvious interlaboratorial differences in nomenclature are recorded

    Introduction. The problem of localization of moving objects inside buildings becomes more urgent in healthcare. Tracking the movements of patients in real time allows one to provide them with timely medical support in case of sharp deterioration in their vital signs. It is especially important to track the location of patients undergoing a surgery, since the risk of death due to postoperative complications for them is extremely high. Using indoor-positioning technologies in telemedicine systems can solve the problem, thereby reducing the mortality rate of patients and improving the quality of medical care.Aim. To study the applicability of magnetometry, inertial and acoustic technologies for patient’s localization in a hospital.Materials and methods. The analysis of domestic and foreign scientific sources devoted to indoor-positioning based on the above technologies was carried out. Material published not earlier than 2016, was chosen for the analysis. Most of the papers were published in journals with impact-factor not lower than 3.Results. After analyzing the information received, it was concluded that none of the technologies can be used independently. Inertial sensors possess high accuracy, but over time, the measurement error increases. There-fore, the sensors need to regular correction. Indoor-positioning based on geomagnetism is hampered by interference that can be induced by the operation of magnetic resonance imaging scanners and X-ray equipment, which are usually used in medical facilities. Active magnetometry does not allow to keep track of moving objects due to specific of hardware used. Ultrasound-based positioning can be complicated by ultrasonography apparatuses interference. Using an audible sound creates noise pollution and exerts a negative impact on patient’s health. Also, acoustic technologies are unable to provide a secure communication channel for data exchange.Conclusion. It is recommended to combine the reviewed positioning technologies with other technologies in order to correct the indicated disadvantages.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Introduction. Localization of objects position in closed space plays an important role in many areas of human activity, including medicine. Using indoor-positioning technologies as a part of telemedicine systems allows one to improve the quality of medical care and to reduce mortality of patients. Therefore, indoor-positioning technologies contribute to achieve the goals outlined in the Russian Federation government`s program "Healthcare development". Aim. To study the applicability of modern radiofrequency technologies for localization of patients inside a hospital building. Materials and methods. Scientific sources devoted to indoor-positioning based on radiofrequency technologies were analyzed. The methods used included: - bibliographic retrieval; - selection and verification of sources based on their relevance; - analysis of sources by methods of deconstruction and comparative analysis . Results. The result of the analysis indicated that radiofrequency positioning technologies allow one to locate objects using radio waves properties. The disadvantage of the technology is the penetration of radio signal through walls and floors. Given this, it is necessary to use complex algorithms to detect an object with accuracy to a specific room. Despite this disadvantage, radiofrequency technologies can be used for positioning in medical facilities since they are easy in deployment and service. Also, they are used in ready-made commercial solutions. ZigBee technology is an exception because it does not allow one to track moving objects in real-time. Conclusion. Based on the study it was concluded that BLE technology is the most suitable for indoor-positioning in medical facilities. It is energy-efficient, it has sufficiently fast data transfer rate, good communication radius and a large range of ready-made communication equipment. It is also worth noting that most wireless medical sensors exchange data via the BLE interface.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.

    Introduction. The development of telemedicine systems intended to remotely monitor the health status of patients constitutes one of the most promising areas of contemporary science. Particularly relevant is the use of such systems to track the health of surgically treated patients. Since such patients are mobile, sensors measuring vital signs should not cause any discomfort in regular use. Thus, wearable smart trackers can be used for these purposes.Aim. The paper aims to study the possibility of using smart trackers in a telemedicine system for monitoring patient health.Materials and methods. In the study, a series of measurements was performed using GSMIN WR 41 smart bracelets in order to estimate their accuracy when measuring pulse, blood pressure, and oxygen saturation for different research subjects at rest and during intense physical exercises. In addition, the average measurement interval of the smart bracelet was determined; the operation of the smart bracelet in the telemedicine system for monitoring vital signs was considered.Results. The studies show that an average error in the measurement of vital signs (except for systolic pressure) using the smart bracelet does not exceed 10 %. In order to avoid the high error in measuring systolic pressure, an algorithm for assessing the general health of patients was developed. In addition, it is shown that the smart bracelet can detect an abrupt change in the vital signs of patients, with the average time of their measurement and data transmission to the server of the telemedicine system coming to 45 seconds.Conclusion. The study results indicate that smart bracelets can be used to remotely monitor the health of patients in real-time. These findings are confirmed by the telemedicine system designed on the basis of the smart bracelets considered in the paper.Π’Π²Π΅Π΄Π΅Π½ΠΈΠ΅.
