Abstract Beavers have recolonized much of their historic range throughout the northern hemisphere and numerous studies have documented their habitat preferences and foraging behavior in rural riparian areas. Beavers, however, are also recolonizing waterways in cities, yet there has been little study of habitat use and foraging practices in these managed, urban systems. We studied beaver lodge distribution and riparian foraging preferences along the South Saskatchewan River, Canada, comparing a reach (24 km) passing through the City of Saskatoon where beavers and trees are managed with an upstream reach (29 km) passing through a conservation area where neither beavers nor trees are managed. In a canoe-based census at low flow, we found that beaver density in the conservation area was twice that in the city. Lodges were dispersed in the city with longer water-based distances between them. We found both differences and similarities in beaver foraging behavior. Riparian tree sampling along transects revealed that while diversity in the city and conservation area is markedly different, beavers preferentially cut green ash, Manitoba maple, paper birch and three poplars in both places. Beavers also cut six other tree species in the city, including three that are introduced, but the diversity was higher. A least-squares general linear model showed greater probability of cutting of trees further from the river in the city than conservation area, but of smaller diameter. Study results will be useful to urban planners in managing urban riparian forests and in developing beaver management plans.

Based on the concept of a livable and global age-friendly city, pavements are a public facility that the city should provide to the people. Appropriate pavements will be beneficial for the people, particularly for good quality of life for the elderly to move around in the city. This study explored the behaviour of the elderly in the use of pavements and the problems confronted. The study also evaluated the value of the pavement walking area as it reflected the benefits of pavements to the elderly by applying the Contingent Valuation Method (CVM). During March-May 2017, data were collected using interviews with 601 elderly living in Bangkok. The study indicated that the main problem for senior citizens regarding their use of pavements was from being disturbed by motorbikes riding on the pavements. The average value of pavement for the elderly was about THB 160 (USD 5.30) per person per year. Thus, the benefits of pavements to the elderly in Bangkok was approximately THB 158 million (USD 5.2 million) per year. Thus, policy makers should make proper budget allocations for elderly-friendly pavement management and seriously address the problems confronting the elderly in using pavements, to maximize the usefulness of pavements not only for the elderly but also for the public and to support a sustainable urban development.

Drawing on field research and a survey of 150 Zimbabwean migrants in Johannesburg, this paper explores the dimensions of migrants’ transnational experiences in the urban space. I discuss the use of communication platforms such as WhatsApp and Facebook as well as other means such as telephone calls in fostering the embedding of transnational migrants within both the Johannesburg and the Zimbabwean socio-economic environments. I engage this migrant-embedding using Bourdieusian concepts of “transnational habitus” and “transnational social field,” which are migration specific variations of Bourdieu’s original concepts of “habitus” and “social field.” In deploying these Bourdieusian conceptual tools, I observe that the dynamics of South–South migration as observed in the Zimbabwean migrants are different to those in the South–North migration streams and it is important to move away from using the same lens in interpreting different realities. For Johannesburg-based migrants to operate within the socio-economic networks produced in South Africa and in Zimbabwe, they need to actively acquire a transnational habitus. I argue that migrants’ cultivation of networks in Johannesburg is instrumental, purposive, and geared towards achieving specific and immediate goals, and latently leads to the development and sustenance of flexible forms of permanency in the transnational urban space.

Постановка задачи. В настоящее время формирование современной комфортной городской среды приобретает особое социально-экономическое значение и выдвигается в число приоритетных государственных масштабных программ. В связи с этим необходимо разработать концепцию благоустройства ключевого общественного пространства, а именно: определить основные и сопутствующие функции данной территории, создать эскизное предложение проекта благоустройства с учетом всех необходимых норм и стандартов, внедрить современные технологии. Результаты. Выполнен эскизный дизайн-проект «Аллеи архитекторов» по ул. Орджоникидзе г. Воронеж, включающий в себя основные элементы по зонированию территории, проектированию акцентных объектов и внедрению инновационных технологий «умного города», позволяющих повысить уровень комфорта горожан. Выводы. Благоустройство населенных мест приобретает особое значение в условиях дискомфорта среды. С выполнением комплекса мероприятий, направленных на благоустройство, и с внедрением современных технологий значительно улучшается экологическое состояние, внешний облик города. Оздоровление и модернизация среды, которая окружает человека в городе, благотворно влияет на психофизическое состояние, что особенно важно в период интенсивного роста городов. Statement of the problem. Currently the formation of the modern comfortable urban environment is gaining a special social and economic value and moving forward in the priorities of state large-scale programs. The purpose of development of the concept of improvement of public space is definition of the main and accompanying functions of this territory, design of the outline offer of the project of improvement considering all necessary norms and standards and implementation of modern technologies. Results. The conceptual project of “Alley of Architects” includes the basic elements of territory zoning, design of accent objects and implementation of technologies of a “smart-city”. These elements allow one to increase the level of comfort of inhabitants. Conclusions. Improvement of the inhabited places is of particular importance in the conditions of discomfort of the environment. Carrying out a complex of the actions directed to gardening and improvement, introducing modern technologies, the ecological condition, the physical appearance of the city considerably improves. Improvement and modernization of the environment which surrounds the person in the city influences a psychophysical state well that especially important during intensive growth of the cities.

Abstract This paper publishes four inscriptions recently discovered by chance in the Cyrenaican countryside. Nos 1, 2 and 3 are in Greek. No. 1, from a tomb near Mgarnes, is a funerary stele inscribed in verse for a woman whose family was of some importance in the city of Cyrene. No. 2, from the same tomb, is an anthropomorphic stele for another woman, which is discussed on the basis of the dead person's name and the vicinity of the stone to the preceding stele. No. 3, from the middle plateau below Cyrene, is a marble panel with the epitaph of two women named Cornelia, increasing our knowledge of the Cornelii family in Cyrenaica. No. 4, from near Khawlan in the south-east, is a boundary stele in Latin mentioning the boundaries of the province; combining this with the evidence from another such stone from el-Khweimat, close to Gerdes el-Gerrari towards the south-east, also mentioning the provincial boundaries, we are now able to outline the Roman limes in the central part of Djebel Akhdar.

Magnetic Resonance Spectra

Minimum numbers of yeasts isolated from the Saskatchewan River in the summers of 1964 and 1965 ranged from 400 to 500 cells/liter upstream from the city of Saskatoon, to 4600 cells/liter immediately downstream. In the summer of 1968, a period of extremely low water, the counts were 150 cells/liter upstream from the city and 30 000 cells/liter downstream.Proton magnetic resonance spectra of the mannose-containing polysaccharides from representative cultures of the different species isolated were used as an aid in classification. Most of the species were asporogenous, and included representatives of the genera Candida, Trichosporon, Rhodotorula, Torulopsis, and Cryptococcus. Some species of Pichia, Saccharomyces, and Debaryomyces were isolated. The yeasts were mostly introduced into the river with the effluent from the Saskatoon sewage system.

This study has developed street lamp lighting device material that was turned on and off by self-power supply without additional power by using the rays of the sun. Lighting devices have been applied with polycarbonate materials that were outstanding with light transmissivity while using LED light and economic value. Lighting devices are easily installed in various places since external power is not necessary. In addition, it also serves as a function of preventing crime by acquiring intensity of illumination in crime-ridden district in the night. Lighting device can also serve as a function of improving fine view in the city by establishing eco-friendly circumstances including parks, areas around shopping district, and housing areas after being manufactured in the form of flowerpot where can grow plants in the future.
