BONE ARTIFACTS FROM ROMAN CREMATION BURIALS: METHODS, RESULTS AND CONCLUSIONS - THE EXAMPLE OF THE CEMETERY OF KAISERAUGST-IM SAGER (CH)
Authors: Deschler-Erby Sabine , Ammann Sandra
Published: February 2020

In the Roman cremation graves from the middle of the 1st century onwards only a few bone artifacts have been found to date. In this article we discuss the methodological problems that lead to this result and how their effects can be minimized in future work. In this way we can show that the types of worked bone from the cemetery of Kaiseraugst-Im Sager differ considerably from the contemporaneous finds from the town of Augusta Raurica.
FIGURAL ROMAN BONE HANDLES FROM MURSA
Authors: Kovač Marina
Published: February 2020

This paper deals with four figural handles from the Collection of Roman Bone Objects of the Archaeological Museum Osijek, Croatia. This Collection holds 19 Roman bone handles divided in four different types: Figural handles, Double-sided knife handles, Various full handles and Cylindrical handles. Three figural bone handles are clasp-knife handles (cultellus) and anthropomorphic displays are featured on two of them – murmillo gladiator and Hercules, with a zoomorphic representation of a pig on the third one. All three objects are made of compact long bone tissue of medium-sized or large mammals. The fourth artefact, probably a patera handle with a lion’s head terminal, is also made of compact long bone tissue of a medium-sized or large mammal. This artefact is clearly a high-quality piece and we believe the object came to Mursa as an import, while the other handles may have been manufactured locally.
LATE MEDIEVAL AND EARLY MODERN BONE AND ANTLER WORKING IN THE VILNIUS CASTLE COMPLEX
Authors: Luik Heidi , Piličiauskienė Giedrė , Blaževičius Povilas
Published: February 2020

Much bone and antler working debris was found from the territory of the Vilnius Castle complex. The bone working debris is rather standardised; most common are sawn off epiphyses of metapodials. Cattle bones prevail among the working waste, metatarsals being much more numerous than metacarpals. Antler working waste is not as standardised as the bone working waste. All parts of antlers are represented in the waste, including both elk antlers and red deer antlers. Shed antlers as well as antlers of hunted animals were used. Presumably the craftsmen working in the Vilnius castles were not specialised in bone or antler working, but used several materials and were rather specialised in the types of products they made.

Green Purchase Intention Pada Konsumen Nutrifood di Bandung: Peran Environment Concern Dengan Mediasi Green Trust
Authors: Marcelino Dandy
Published: February 2020

Dalam beberapa tahun terakhir, pemanasan global telah menjadi subjek kontroversi perbincangan, dan juga telah mengubah ritme iklim yang berpengaruh terhadap semua kehidupan di Bumi. Di Indonesia, pencemaran udara mulai meresahkan masyarakat sejak banyaknya pabrik yang membuang limbah sisa pembakaran ke udara sehingga akan berdampak terhadap pencemaran lingkungan. Berdasarkan fenomena tersebut, akan berdampak pada peningkatan jumlah perusahaan yang mengusung program “Green Company” di Indonesia yang bertujuan untuk mengurangi penggunaan energi maupun pengurangan limbah pabrik. Dalam menerapkan konsep green (ramah lingkungan), perusahaan harus menumbuhkan rasa kepedulian konsumen terhadap lingkungan “environment concern” sehingga menimbulkan rasa percaya konsumen terhadap produk hijau “green trust” serta berdampak kepada minat konsumen untuk membeli produk hijau tersebut “green purchase intention”. Metode penelitian yang digunakan dalam penelitian ini adalah metode kuantitatif dengan pendekatan deskriptif kausal, dengan menggunakan teknik analisis Structural Equation Modeling (SEM) menggunakan software SMART PLS 2.0. Adapun metode pengambilan sampel yang digunakan adalah accidental sampling dengan total 400 responden.

Experience in assessing the dynamic state of vegetation based on a large-scale map of modern vegetation (on the example of the area “Levashovskiy les”, St. Petersburg)
Authors: Volkova E. A. , Khramtsov V. N.
Published: February 2020

The article is devoted to the vegetation mapping of the “Levashovskiy les”— a large forest-mire massif located in the northern part of St. Petersburg (Fig. 1). It continues a series of articles on the vegetation of existing and proposed specially protected natural areas of St. Petersburg (Volkova, Khramtsov, 2018). Large-scale map of modern vegetation (Fig. 2) is presented; the map legend includes 67 main numbers, the signs and numeric indexes at the numbers made it possible to show 93 mapping units (associations and their variants). Brief description of the main types of plant communities (spruce, pine, birch, aspen, gray alder and black alder forests; raised bogs, transitional mires and fens, floodplain and upland meadows) reveals the content of the legend. Vegetation cover is characterized by the dominance of secondary communities. The main anthropogenic impacts on modern vegetation are following: drainage reclamation, deforestation and former agricultural use, forest fires, gas pipelines, highways. Most of the forest communities are secondary ones; they have grown under the pressure of various anthropogenic factors and at different time. Nowadays an active process of natural regeneration of conife­rous (mainly spruce) trees goes in the forests. Plant community structure and species composition were taken into account as well as their dynamic state. To assess the degree of disturbance of plant communities and the potential for their restoration, the analysis of all mapped vegetation categories with respect to their position in the ranks of restorative successions was made. Then an assessment map “Dynamic state of plant communities” (Fig. 3) was compiled. The map shows following categories of dynamic types of communities: conventionally primary; relatively long-term secondary and stable long-term secondary (Sukachev, 1938; Isachenko, 1964; Karpenko, 1965; Gribova, Isachenko, 1972); short-term secondary that were divided into 3 categories representing different stages of restorative series. Present state of the vegetation cover of the “Levashovskiy les” can be determined by the ratio of the areas of conventionally primary and secondary communities. Areal analysis of dynamic categories of plant communities showed that only a bit more than 20 % of the territory is occupied by conventionally primary communities and about 60 % – by short-term secondary ones with good restorative potential. Without strong anthropogenic and natural disturbances, a significant part of the disturbed plant communities will be able to self-restore to their natural state. The establishment of a specially protected natural area as well as the regulation of conservation regime will support restoration process of nature ecosystems.
Europe’s New Bildungsbürger? Chinese Migrants in Search of a Pure Land
Authors: Pál Nyíri , Fanni Beck
Published: February 2020

The recent wave of the emigration of well-to-do Chinese from the People’s Republic of China (PRC) has been attracting attention. Like earlier migrants, these individuals go abroad to seek a better life—but they no longer define that as higher income, better welfare, or even better education. Rather, these migrants pursue better environmental quality, safer food, and a more relaxed environment in which to raise children. Although the wealthiest of these lifestyle migrants, who move to North America, Australia, or New Zealand, have attracted the most attention, middle-class migrants have been taking advantage of lower-cost residence-for-investment schemes. This article explores the motivations of some of the twenty thousand Chinese who moved to Hungary between 2013 and 2017 and argues that the country’s official xenophobia and law-and-order policies make it a more, rather than less, desirable destination for those Chinese pursuing a “European lifestyle.” This migration wave represents a turn in the long history of how Chinese migrants interact with the world and relate to China, a turn that requires more attention in the studies of Chinese overseas. Simultaneously, it sheds light on how cosmopolitanism and global mobility can coexist with support for the new global populism.

Authors: He Y. , Wu H.-M. , Guo J.-B. , He W.-D. , Zhou Y.
Published: February 2020

Natural fiber reinforced polymer composites have the advantages of low density, low cost and renewability. However, the inferior mechanical property restricts the application. In this work, EPDM-g-GMA has been added to straw/PP composites to improve the properties. The mechanical properties, thermal stability, crystallinity and melt viscosity have been invested. The results reveal that the mechanical properties of straw/PP/EPDM composites are improved remarkably and the impact strength more than doubles compared to straw/PP composites. Surface microstructure analysis reveals that the composite has good interfacial compatibility and dispersing performance. The maximum decomposition temperature, the melting enthalpy and crystallinity increased. The glass transition temperature and process ability are also improved by the addition of EPDM.

Ukraine in the Contemporary Integration Processes: Preconditions and Problems
Authors: IHNATENKO Т. , PARKHOMENKO V. , TARASENKO А.
Published: February 2020

Given that the economic and social recovery of Ukraine is largerly conditional on its integration in the international economic system and effective involvement in the international division of labor, the article’s objective is to analyze preconditions and problems specific to the Ukraine’s integration in the global economic area. Intergration-specific aspects and problems in operation of the transport infrastructure and mining industry of Ukraine, strong and weak sides of Ukraine on the global energy market, the potentials of Ukraine in the agrarian sector are highlighted. It is emphasized that a priority mechanism for increasing the share of Ukraine’s trade on the European agrarian market is Free Trade Zone with EU, but a factor constraining growth in the agricultural exports of Ukraine to EU is failure of the most part of domestic producers to comply with technical, sanitary etc. terms for exporters to EU. The analysis covers statistical data on foreign trade of Ukraine in goods and services in 2016–2018, the commodity structure of Ukraine’s foreign trade in 2018, key indicators of the international trade of Ukraine in 2016–2018. It, above all, shows the negative balance of the Ukrainian foreign trade, which tendency is upward. The tradability index for the Ukrainian economy fell in this period from 81.0% до 79.9%, giving evidence of the decreasing participation of Ukraine in the international division of labor. The essential factors underlying the negative balance of foreign trade in goods are highlighted; measures to reduce the negative balance of foreign trade are proposed. The data showing the progress in Ukraine’s implementation of Association Agreement with EU are summed up. It is concluded that in spite of a series of steps towards the openness of Ukraine for the global market, the processes involved in the formation of the national foreign economic relations mechanism have been contradictory and ineffective. It calls for optimization of regulatory forms for foreign economic relations and implementation of a mechanism complying with the current terms of international economic relations.

Analysis of the demand for the results of scientific activity in the main areas of Earth Sciences
Authors: Arutyunov V. V.
Published: February 2020

The paper analyzes the importance of geological knowledge for solving a wide range of practical problems. The purpose of this study is to evaluate the results of the research of scientists and specialists in 2012–2018 in Geology, Geophysics, Geography, Mining, Geodesy and cartography on the basis of RSCI databases (Russian science citation index). The analysis was carried out taking into account a number of scientometric indicators: the publication activity of researchers – the annual number of their publications, as well as the citation of these publications and the demand for the results of their work. Features of publication activity are revealed: high values of its indicators for Geology and Geophysics and minimum values – for Geodesy and cartography; thus the number of publications on Geography and Mining approximately coincide. For Geology, there is stability in the number of publications since 2015, while in other analyzed industries there is a decline in the number of publications since 2017. Citation rates for all years under review are continuously decreasing. At the same time, in the field of Geophysics, citation rates are 3–4 times higher than similar indicators for Geography, and 7–9 times – indicators for Mining. The most popular are the results of research in Geophysics, the least – in the field of Geodesy and cartography. At the same time, if the annual demand for the results of studies in Geophysics exceeds similar indicators for Geography by 15–20%, for Geodesy and cartography – about 1.5 times. Low demand for all areas of research in 2018. The reason is obviously the same as for the small citation indicators this year: the delayed "response" of the scientific community to the publications of the current year.

Published: February 2020

ABSTRACT. This article analyses the main features of respiratory protective equipment used during combat actions under the conditions of chemical and radiation contamination.

Objective: To study the technical characteristics of respiratory protective equipment that the Armed Forces of Ukraine are equipped with for compliance with NATO standards.

Materials and methods. Analysis of sources of scientific information about respiratory protective equipment in operational service with Ukraine and NATO have been conducted. Study methods used: analytical, historical, bibliographic, systematic and informational approach.

Results and discussion. It was established that the majority of respiratory protective equipment that the Armed Forces of Ukraine are equipped with has been manufactured before 1991. Their shelf lives exceed the acceptable ones, and the standards by which they were manufactured do not meet modern requirements. The authors have defined the principal directions for improving respiratory protective equipment: versatility for various tactical tasks; possibility of use along with optical devices; compliance of intercommunication systems and breathing valves with NATO standards; providing respiratory protection against a wide range of chemicals; long shelf life; resistance to special treatment means (degassing); possibility of rapid switch to combat position; portability and ease of use.

Conclusion. Modern technical characteristics of respiratory protective equipment should comply with the nature of the threats and the best international standards. An important direction in the development of weaponry and military equipment in Ukraine is the improvement of domestic technologies and development of own production of personal protective equipment, technologically compatible with the samples that are in the operational service with NATO countries.

Keywords: military toxicology, military radiology, medical protection, respiratory protective equipment.

Within the fields of biology and ecology, animal movement is arguably one of the most basic, and yet, often one of the most difficult areas of study. Where and why animals migrate, and what patterns can be derived from individual movements in order to make population-level inferences are key areas when attempting to define basic population dynamics. These questions are of equal interest to biologists and managers, with many species assessments identifying improvements in the understanding of population-level movement as a key research need. We aimed to improve our understanding of population level movement for common thresher sharksAlopias vulpinusby leveraging the largest satellite tagging dataset available for this species. Using a Bayesian approach specifically designed to address population-level questions with sparse telemetry data, we identified thatA. vulpinusoff the west coast of North America are partial migrators which conditionally migrate, based on a combination of fixed intrinsic states (size, sex) and variable extrinsic states (e.g. season, environment). Waters of the Southern California Bight were identified as an area where, seasonally, a large variety of sizes ofA. vulpinuscan be found. While smaller juveniles can be found throughout the year, larger sub-adults and adults often move out of the Bight during certain seasons (spring and winter). Knowledge of howA. vulpinusdistribute along the coast, and that season, size, and to some extent sex, play important roles in where and what type of animals are likely to be found, are key pieces of information when attempting to accurately characterize basic biological parameters like age, growth, and reproduction, as well as understanding the effects of variable fishing pressures across the species’ range.

Isolated beef heart mitochondria have been exposed to tert-butyl hydroperoxide (tBHP) and peroxynitrite (PeN) in order to model the effects of reactive oxygen and nitrogen species on mitochondria in vivo. The formation of malondialdehyde (MDA), protein carbonyls, lipofuscin-like pigments (LFP), and nitrotyrosine was studied during incubations with various concentrations of oxidants for up to 24 h. The oxidants differed in their ability to oxidize particular substrates. Fatty acids were more sensitive to the low concentrations of tBHP, whereas higher concentrations of PeN consumed MDA. Oxidation of proteins producing carbonyls had different kinetics and also a probable mechanism with tBHP or PeN. Diverse proteins were affected by tBHP or PeN. In both cases, prolonged incubation led to the appearance of proteins with molecular weights lower than 29 kDa bearing carbonyl groups that might have been caused by protein fragmentation. PeN induced nitration of protein tyrosines that was more intensive in the soluble proteins than in the insoluble ones. LFP, the end products of lipid peroxidation, were formed more readily by PeN. On the other hand, fluorometric and chromatographic techniques have confirmed destruction of LFP by higher PeN concentrations. This is a unique feature that has not been described so far for any oxidant.

Cultivation of winter wheat under reduced tillage systems is increasing in the U.S. Southern Great Plains. Likewise, there is revived interest for including summer legumes in monocultures of winter wheat as green sources of nitrogen (N). This study investigated the influence of tillage systems (no- and conventional tillage), and source and rates of N fertilizer (0, 45 and 90 kg N ha−1 yr−1 in inorganic N fertilizer, and cowpea as green manure) on emissions of carbon dioxide (CO2) and nitrous oxide (N2O) from winter wheat cultivation. The study was conducted within a long-term field experiment initiated in 2011, at upland and bottomland sites near El Reno, Oklahoma during the 2016–2017 growing season of winter wheat. The experiment was conducted site-wise as split-plots in a completely randomized design, with N treatment as main plots and tillage system as subplots. Thus, there were a total of eight treatment combinations with three replicated plots (4 m × 10 m) in each combination in both sites. Net ecosystem exchange (NEE) of CO2 was measured by a closed chamber connected to an infra-red gas analyzer, and fluxes were partitioned to gross primary production (GPP) and ecosystem respiration (ER). Heterotrophic soil respiration (SR) was measured on bare soil spots. Fluxes of N2O were measured with an opaque closed chamber system with a portable gas analyzer. Dynamics of canopy CO2 fluxes (NEE, GPP and ER) were similar between tillage systems, while canopy CO2 fluxes increased with rate of N fertilization. Canopy CO2 fluxes from cowpea and an unfertilized control were similar, and the lowest, due to poor growth of winter wheat compared to the N fertilized treatments. Fluxes of N2O approximated zero from all treatments throughout the study and no response of N fertilizer or tillage system was seen. In conclusion, the results from this study indicated that canopy fluxes of CO2 from winter wheat are controlled by forms and rates of N fertilizers rather than tillage systems.

Reduced mobility in broilers can contribute to leg health problems. Environmental enrichment has been suggested as one approach to combat this through stimulating increased physical activity. Past studies have tested the effect of environmental enrichments on bird behaviour, health and welfare, but few have estimated their financial impacts. This study tested the impact of eight types of environmental enrichment on enterprise net margin, accounting for direct intervention costs plus indirect effects via changes to bird mortality, weight, feed intake, feed conversion ratio, and foot pad dermatitis. The trial used 58 pens each containing approximately 500 broilers (Ross 308) at a stocking density of 40 kg/m2. The environmental enrichments were: roughage, vertical panels, straw bales, elevated platforms (5 and 30 cm), increased distances between feed and water (7 and 3.5 m) and stocking density reduced to 34 kg/m2, plus a control group. Mortality was recorded daily and feed intake and weight weekly. Footpad dermatitis was assessed on day 35. Only one intervention improved financial performance (3.5 m between feed and water) above the control, suggesting that most environmental enrichment would have a negative financial impact due to the additional intervention costs, unless consumers were willing to pay a price premium.

The present study aimed to investigate the effect of maternal water restriction on sexual behavior, reproductive performance, and reproductive hormones of male rat offspring. Forty pregnant female rats were divided into two equal groups: Control (C) and water-restricted (WR). Control dams had ad libitum water access throughout pregnancy, while dams in the WR group were subjected to 50% water-restriction from day 10 of pregnancy onwards. The maternal water restriction provoked a significant reduction (p < 0.05) in body weight of dams before delivery and at birth and litter body weights of offspring at birth. Maternal water restriction did not affect relative weights of reproductive and body organs of male rat offspring. All hormonal concentrations, sperm count, and vitality in male rat offspring were not significantly affected by maternal water restriction. Maternal water restriction exposure induced significant (p < 0.05) reduction in intromission latency, intromission frequency, and post-ejaculation interval in male rat offspring while a significant (p < 0.05) increase in the ejaculation latency was detected in maternal WR group. In conclusion, this study suggests that maternal water restriction had a negative impact on some reproductive characteristics but did not severely affect reproductive performance and reproductive hormones of male rat offspring.

Sepsis is a life-threatening response to infection associated with inflammation, oxidative stress and mitochondrial dysfunction. We investigated differential effects of three forms of vitamin E, which accumulate in different cellular compartments, on oxidative stress, mitochondrial function, mRNA and protein expression profiles associated with the human Toll-like receptor (TLR) -2 and -4 pathways. Human endothelial cells were exposed to lipopolysaccharide (LPS)/peptidoglycan G (PepG) to mimic sepsis, MitoVitE, α-tocopherol, or Trolox. Oxidative stress, mitochondrial function, mitochondrial membrane potential and metabolic activity were measured. NFκB-P65, total and phosphorylated inhibitor of NFκB alpha (NFκBIA), and STAT-3 in nuclear extracts, interleukin (IL)-6 and IL-8 production in culture supernatants and cellular mRNA expression of 32 genes involved in Toll-like receptor-2 and -4 pathways were measured. Exposure to LPS/PepG caused increased total radical production (p = 0.022), decreased glutathione ratio (p = 0.016), reduced membrane potential and metabolic activity (both p < 0.0001), increased nuclear NFκB-P65 expression (p = 0.016) and increased IL-6/8 secretion (both p < 0.0001). MitoVitE, α- tocopherol and Trolox were similar in reducing oxidative stress, NFκB activation and interleukin secretion. MitoVitE had widespread downregulatory effects on gene expression. Despite differences in site of actions, all forms of vitamin E were protective under conditions mimicking sepsis. These results challenge the concept that protection inside mitochondria provides better protection.
