Presented are the isolines maps for the distribution of inhomogeneous values of acid-alkaline medium and biochemical activity levels of soils in the industrial city of Bratsk in the settings of Eastern Siberia. The maps were constructed from point measurements in the geoinformation environment by the IDW Nearest Neighbors method. The soil biochemical activity was analyzed by using the proximate method according to T. V. Aristovskaya and M. V. Chugunova. It is shown that the activity of urban soils varies from strong to moderate. The soils with high activity occupy 75,3 % of the total area of the city. The acid-alkaline conditions of soils are transformed considerably toward the alkaline side. On the hole, the alkaline and highly alkaline soils occupy 96% of the territory. A high level of soil biochemical activity has been revealed. This study deals with the transformation of nitrogen-containing organic compounds leading to a loss of biogenic nitrogen by the soil.

Results from studying urbanized territories highly depend on approaches and methods of interpreting data obtained in the course of investigations. A case study was made in the industrial city of Usolye-Sibirskoe (Irkutsk oblast, RF) to investigate and map the current ecological-and-biochemical status of soil cover affected by urbanization and technogenesis. T. V. Aristovskaya’s and M. V. Chugunova’s rapid method was used to reveal high indicators of the level of alkaline-acid conditions and biochemical activity of urban soils. The mapping enabled identification of the local features of the urban territory. A considerable part of it is occupied by soils with weak alkaline pH index (7.3–8.0). In absolute values, it is 6083.3 ha, or 77.2 %. The study determined a high and very high level of the soil biochemical activity. They occupy a large area of 6079.2 ha, i.e. 76 % of the city. A substantial increase in soil biochemical activity can lead to loss of a biogenous element, nitrogen, and this cannot be regarded as a positive phenomenon. Experimental data on the SBA – рН system for the residential zone of the city made it possible to determine a close correlation between them to be statistically significant.

This experimental work was done before the stopping the Baikalsk Paper and Pulp Mill. As the informative criteria for the present state of anthropogenic soils used in this study the degree of their biochemical activity and the acid-alkaline conditions which belong to integral indicators was taken. The basic technique for carrying out mass analyses of biochemical activity of soils characterizing the territory of the city of Baikalsk was the rapid analysis method suggested by T. V. Aristovskaya and M. V. Chugunova. The study revealed a high level of soil activity in all functional zones of the city. The acid-alkaline contents were determined for the soils under investigation, which showed a wide range of values (from 6,7 to 8,5 рН). On the basis of the data obtained and point measurements in the geoinformation environment the IDW Nearest Neighbors method was used to construct isopleth maps. A trend for a weak but positive correlation was revealed between the acid-alkaline conditions and soil biochemical activity. All the findings provide a basis for further monitoring the post-technogenic recovery of the city’s soil ecological status in the setting of Southern Baikalia.

The results of a study of the state of soil cover in the sphere of influence of an industrial city in the conditions of Eastern Siberia are presented. In the town of Usolye-Sibirskoye (Irkutsk region), industrial nature use dominates. The acid-alkaline conditions of the soils of the city were transformed relative to the background soils. An assessment of the biochemical activity of soils is given as an integral indicator, which was assessed by the express method. Three groups of soils were identified according to the level of their activity. The diversity of soil microbiocenosis has been established. A tendency towards a decrease in the qualitative composition of microscopic fungi in industrial zones has been noted. It is recommended to increase the planting area of woody vegetation (poplar, birch, Siberian pine, fir, bird cherry, wild rose) and sowing herbs (clover, sweet clover, timothy grass, and bluegrass) to improve the environment.

AbstractThe rise of crack cocaine in the late 1980s propelled the war on drugs. The experience of Canton, Ohio, shows how the response to crack solidified mass incarceration. A declining industrial city of 84,000 people in northeast Ohio with deep-seated racial divides, it was overwhelmed by aggressive, enterprising crack dealers from outside the city. In response, politicians and residents united behind the strategy of incessant arrests and drastic prison sentences. The law-enforcement offensive worsened conditions while pursuing African Americans at blatantly disproportionate rates, but few people engaged in reframing the drug problem. Instead, a punitive citizenry positioned punishment as the principal remedy. The emergency foreclosed on more comprehensive assessments of the city’s tribulations, while the criminal justice system emerged as the paramount institution.

Children’s health literacy is a crucial pillar of health. This study is aimed to examine the association between health literacy and weight status among Greek schoolchildren aged 10 to 12 years old. A population-based, cross-sectional observational study enrolling 1,728 students (795 boys), aged 10 to 12 years old, was conducted during school years 2014–2016. A health literacy index (range 0-100) was created through an item response theory hybrid model, by combining a variety of beliefs and perceptions of children about health. The mean health literacy score was 70.4 (±18.7). The majority of children (63.8%) had a “high” level (i.e., >67/100) of health literacy, 30.5% had a “medium” level (i.e., 34–66/100) of health literacy, while a small proportion of children (5.7%) had a “low” level (i.e., <33/100). Girls exhibited a higher level of health literacy than boys (71.7 ± 18.3 vs. 68.8 ± 19.1, p < .01). Regarding body weight status, 21.7% of children was overweight and 5.0% was obese. Linear regression models showed that the health literacy score was inversely associated with children’s body mass index (regression coefficient [95% CI]: −0.010 [−0.018, −0.001]), after adjusting for dietary habits, physical activity levels, and other potential confounders. Health literacy seems to be a dominant characteristic of children’s weight status; therefore, school planning, as well as public health policy actions should emphasize on the ability of children’s capacity to obtain, process, and understand basic health information.

In Japan, any high level radioactive waste (HLW) repository is to be constructed at over 300 m depth below surface. Tunnel support is used for safety during the construction and operation, and shotcrete and concrete lining are used as the tunnel support. Concrete is a composite material comprised of aggregate, cement and various admixtures. Low alkaline cement has been developed for the long term stability of the barrier systems whose performance could be negatively affected by highly alkaline conditions arising due to cement used in a repository. Japan Atomic Energy Agency (JAEA) has developed a low alkaline cement, named as HFSC (Highly Fly-ash Contained Silicafume Cement), containing over 60 wt% of silica-fume (SF) and fly-ash (FA). HFSC was used experimentally as the shotcrete material in construction of part of the 140m deep gallery in the Horonobe Underground Research Laboratory (URL). The objective of this experiment was to assess the performance of HFSC shotcrete in terms of mechanics, workability, durability, and so on. HFSC used in this experiment is composed of 40 wt% OPC (Ordinary Portland Cement), 20 wt% SF, and 40 wt% FA. This composition was determined based on mechanical testing of various mixes of the above components. Because of the low OPC content, the strength of HFSC tends to be lower than that of OPC. The total length of tunnel using HFSC shotcrete is about 73 m and about 500 m3 of HFSC was used. The workability of HFSC shotcrete was confirmed in this experimental construction.

AbstractThis paper compares findings on the distribution of support networks in the City of Liverpool and in rural communities in North Wales. It demonstrates that while support network type is highly correlated with a wide range of demographic and social variables in both urban and rural samples, the nature of the relationships are not always comparable. The paper shows how cultural, migration and socio-economic factors interact to affect the formation of different types of support networks. As a result of a more stable elderly population, more old people in Liverpool have network types able to provide a high level of informal care and support.

Abstract Understanding of the evolutionary histories of many genes has not yet allowed us to predict the evolutionary potential of those genes. Intuition suggests that current biochemical activity of gene products should be a good predictor of the potential to evolve related activities; however, we have little evidence to support that intuition. Here we use our in vitro evolution method to evaluate biochemical activity as a predictor of future evolutionary potential. Neither the class C Citrobacter freundii CMY-2 AmpC β-lactamase nor the class A TEM-1 β-lactamase confer resistance to the β-lactam antibiotic cefepime, nor do any of the naturally occurring alleles descended from them. However, the CMY-2 AmpC enzyme and some alleles descended from TEM-1 confer high-level resistance to the structurally similar ceftazidime. On the basis of the comparison of TEM-1 and CMY-2, we asked whether biochemical activity is a good predictor of the evolutionary potential of an enzyme. If it is, then CMY-2 should be more able than the TEMs to evolve the ability to confer higher levels of cefepime resistance. Although we generated CMY-2 evolvants that conferred increased cefepime resistance, we did not recover any CMY-2 evolvants that conferred resistance levels as high as the best cefepime-resistant TEM alleles.

Based on a comprehensive assessment of the state of the park landscape, the level of its anthropogenic transformation is determined, which is necessary to identify the potential for restoring the natural biodiversity of the object. It is reported that the plantations and soil cover of the park of the 50th anniversary of VLKSM are very heterogeneous; they reflect the history of park establishment. The soil cover consists of three main types: sod, bog and urbanozem. It should be stressed that the best preserved part of the park is the plot with boggy soils around the pond. Herbaceous plants growing on the plot are very similar to the species composition of the ground cover of overgrown peat bogs. Over the 40 years since the foundation of the park, a high level of pollutants has been accumulated in the soil, which allows us to state that the negative impact occurs constantly. Consequently, the existing plantings are insufficient to protect visitors from vehicle emissions from the roads along Yasnaya and Shaumyana streets. There are enough natural elements in the park of the 50th anniversary of VLKSM; this should be taken into account in its redevelopment. There is an opportunity to restore the reservoir and return the plantings to their natural appearance. It is proposed to add elements of landscape decoration in the park.

Trees And Shrubs

The article deals with one of the most relevant topics of the modern city and ecology - the problem of landscaping in Volgograd. The city is characterized by an industrial urbanism, with a high concentration of population, saturation of production facilities and vehicles, which contributes to a high level of negative impact on the environment. The pace of greening of the city lags behind the pace of construction of the residential sector, and the existing green spaces do not meet the sanitary and hygienic, aesthetic requirements. The prospects of this problem are determined, the existing green spaces are considered, data on the climatic conditions of the city and the ecological situation are given. Improvement in the field of landscaping is associated with the scientifically sound placement of green spaces, taking into account all the factors that affect the growth and development of plants in the urban environment. Unfortunately, due to the uneven distribution of the assortment of trees and shrubs, the species composition of the central streets and squares of the city is extremely poor. The study focuses on the role of the botanical garden in urban landscaping and aims to create recommendations for the sorting of tree and shrub plants for urban landscaping. As a result of the analysis of the assortment of ornamental plants of the open ground of the botanical garden, the article proposed species and varieties of woody and shrubby plants that have passed the introduction tests for more than 5-10 years. Recommendations for sorting are aimed at improving the ecological situation of the city and greening the recreation areas of citizens. The proposed list of tree and shrub species cannot fully solve the problem of greening the city, but it will help to significantly enrich the composition of tree and shrub plants.
