Microbiological Indicators

Sanitary and microbiological researches of a coastal surface water of the southern part of Lake Baikal (from the Listvyanka to the Tanghui) were conducted in June, 2017. Total number of bacteria varied over a wide range – from 0.93 million сells/ml up to 2:05 million сells/ml, with an average 1.41 ± 0.3 million сells/ml. Biomass of bacteria varied from 11.05 to 305.00 mg С/m3, with an average of 123.34 mg С/m3. Coastal waters of the southern site of Lake Baikal mainly had a beta-meso-saprobic status in June, 2017. The total microbial number was determined with the use of the test systems for the first time. The values of the total microbial number were less than 1 000 COU/ml and varied from 9 to 412 COU/ml. Innovative test systems Petrifilm are of great interest for rapid assessments of the sanitary and microbiological status of reservoirs directly in the field conditions.

In this paper structural, optical, photoluminescence, and photocatalytic properties of TiO2and TiO2:(2.6 at. % Tb) thin films have been compared. Thin films were prepared by high-energy reactive magnetron sputtering process, which enables obtaining highly nanocrystalline rutile structure of deposited films. Crystallites sizes were 8.7 nm and 6.6 nm for TiO2and TiO2:Tb, respectively. Surface of prepared thin films was homogenous with small roughness of ca. 7.2 and 2.1 nm in case of TiO2and TiO2:Tb samples, respectively. Optical properties measurements have shown that the incorporation of Tb into TiO2matrix has not changed significantly the thin films transparency. It also enables obtaining photoluminescence effect in wide range from 350 to 800 nm, what is unique phenomenon in case of TiO2with rutile structure. Moreover, it has been found that the incorporation of 2.6 at. % of Tb has increased the photocatalytic activity more than two times as compared to undoped TiO2. Additionally, for the first time in the current state of the art, the relationship between photoluminescence effect, photocatalytic activity, and surface properties of TiO2:Tb thin films has been theoretically explained.

The mobile technology gained widespread use and became an essential part of all advanced industries over the past decade. Libraries also cannot ignore them, so mobile library applications have become one of the most relevant technological innovations in library activities. Now more and more libraries offer their websites in the mobile version. However, the capabilities of library mobile applications are not limited to providing access to basic services on the library website. The aim of the article is to analyse the functionality of specially developed applications of the Bavarian State Library (FRG), which are aimed at solving specific tasks. On the basis of a wide range of domestic and mainly German sources (articles, monographs, web resources), the author analyses the aspects of using the four mobile applications in the practice of one of the largest German libraries. It is shown that mobile applications can help to reveal unique publications stored in special collections of the library. It is noted that mobile application can be a navigator in a multi-storey library building with a developed infrastructure. The author stresses that the above tasks are achieved due to the extended functionality of the applications: user geolocation, augmented reality, effective reading modes as well as Bluetooth data transfer technology. For the first time, the author considers the mobile applications used in German library practice, which are aimed at meeting special needs of users (study of topography of the region, acquaintance with works of cultural and artistic value, navigation inside the library building). The analysed tendencies of use of the mobile applications can be of interest also for domestic libraries which strive to increase efficiency of work through implementation of mobile technology.

At present, the problem of establishing disability is a point at issue in Russia. Despite the fact that medical criteria for disability are being developed very actively, high-quality methods for assessing social hallmarks are still lacking. Since disability is a phenomenon inherent in any society, each state forms a social and economic policy for people with disabilities in accordance with its level of development, priorities and opportunities. We have proposed a three-stage model, which includes a system for the consistent solution of the main tasks aimed at studying the causes and consequences of the problems encountered today in the social protection of citizens with health problems. The article shows why the existing approaches to the determination of disability and rehabilitation programs do not correspond to the current state of Russian society and why a decrease in the rate of persons recognized as disabled for the first time does not indicate an improvement in the health of the population. The authors proposed a number of measures with a view to correcting the situation according to the results of the study.

The concept of a new approach to environmental assessment is offered in the system of integrated management of the resource and environmental safety of the coastal area of the Black Sea. The studies of the season and daily changeability in the bioluminescence field in the Sevastopol coastal waters has been conducted. For the first time considerable differences in the bioluminescence field seasonal changes in the surface and deep water layers and the reasons conditioning this phenomenon have been shown, using a method of multidimensional statistical analysis. The bioluminescence field vertical profile change in the Black sea coastal waters in the autumn period at night has been studied. It has been shown that according to the character of bioluminescence parameters dynamics a water column can be divided into layers: upper (0 – 35 m) and deep water (36 – 60 m). It has been revealed that life rhythms of the plankton community are the main reason for the bioluminescence field intensity variability. It has been revealed that 14-hour periodicity of the bioluminescence field is related to the changes in light and its variations with 2,5…4,5 hours are conditioned by planktonts endogenous daily rhythms. And here biotic factors effect mostly periodicity of the bioluminescence field intensity increase and fall down at the dark time of the day. Abiotic factors are of less importance in circadian rhythmic of the bioluminescence field in the neritic zone.

Byzantine medicine is still a little-known and misrepresented field not only in the wider arena of debates on medieval medicine but also among Byzantinists. Byzantine medical literature is often viewed as ‘stagnant’ and mainly preserving ancient ideas; and our knowledge of it continues to be based to a great extent on the comments of earlier authorities, which are often repeated uncritically. This book presents the first comprehensive examination of the medical corpus of, arguably, the most important late Byzantine physician John Zacharias Aktouarios (c.1275–c.1330). The main thesis is that John’s medical works show an astonishing degree of openness to knowledge from outside Byzantium combined with a significant degree of originality, in particular, in the fields of uroscopy, pharmacology, and human physiology. The analysis of John’s edited (On Urines and On Psychic Pneuma) and unedited (Medical Epitome) works is supported for the first time by the consultation of a large number of manuscripts. The study is also informed by evidence from a wide range of medical sources, including previously unpublished ones, and texts from other genres, such as epistolography and merchants’ accounts. The contextualization of John’s works sheds new light on the development of Byzantine medical thought and practice, and enhances our understanding of the late Byzantine social and intellectual landscape. Finally, John’s medical observations are also examined in the light of examples from the medieval Latin and Islamic worlds, placing his medical theories in the wider Mediterranean milieu and highlighting the cultural exchange between Byzantium and its neighbours.
