Electricity is the prime mover of every economy; hence there is a need to maintain its generation, distribution and consumption. This study was carried out to appraise the status of electrical wiring in the Isoko area of Delta State, Nigeria. A total of 300 residential buildings, 200 makeshift shops and 100 artisan workshops were sampled and their structures, state of connection, overvoltage protection (cut-out fuse) and earthing were accessed. 100 questionnaires were distributed to electricians involved in electrical wiring and installations in the study area. Results obtained from the questionnaires revealed that only 71% of the residential buildings, 23% of the makeshift shops, and 8% of the artisan workshops made use of electric cables that met the NIS recommendations. For electric cable connections, it was observed that there was a lapse in the connections; mostly in the artisan workshops, as some service cables were not properly tightened to the distribution lines. Only 75% of the residential buildings, 53% of the makeshift shops, and 5% of the artisan workshops had approved rating cut-out fuse. It was observed that in artisan workshops, welding machines were connected directly to the service lines. Furthermore, the results revealed that 42% of the residential buildings, 87% of the makeshift shops and 99% of the artisan’s workshops lacked proper earthing. These results revealed electrical risks in many makeshift shops and artisan workshops and the need for the relevant authorities to act fast to minimize power outrage and prevent electrical tragedies in the study area.

The City

The aim of the article is to highlight the actual trends associated with architectural construction and identify ways of forming a visual image of a modern city. The solution to this goal involves not only the analysis of certain unique architectural structures, but also the outline of the existing visual practices in the city which correlate with the urban landscape. The research methodology is connected with the use of the method of synthe- sis, the use of tools of cultural analysis. The most extraordinary buildings are rarely residential buildings, much more often they are intended for public use. Their very essence is con- nected with publicity and attraction of a considerable quantity of visitors, tourists. These can be museums, libraries, concert halls, stadiums, shop- ping malls. In addition to these structures, extremely impressive structures are created in the field of transport – bridges, railway stations. The re- equipment of old objects and the creation of new ones becomes such that necessarily creates an occasion for communication, becoming a part of the media. In architecture there is a desire to circumvent the principle of statics that was inherent to it. Manifestations of this tendency in architecture were attempts to "revitalize" the building, giving them mobility through structures that visually convey the idea of fluidity (asymmetric structures, often deprived of straight angles with the prevalence of rounded parts). Creating the effect of architectural variability arises not only at the expense of innovative constructions, but also due to the equipment of the buildings by media facades, which perform as a purely aesthetic and advertising function, providing the opportunity to represent buildings in fundamentally different visual images. Scientific novelty consists in highlighting the specifics of architectural constructions claiming the status of "art" and visual practices that in- teract with them directly. The conclusion is made about the transformation of a modern city. The practical significance of the study is that features of the development of modern architectural constructions are presented and the factors influencing the formation of the visual image of the city are highlighted.

Indoor air pollution level in dwellings varies in different areas. Specifically, the formaldehyde and total volatile organic compound pollution are serious in new residential buildings according to the investigation of indoor air pollution status of residential buildings in China. Appropriate ventilation, as an important means to reduce the concentration of indoor pollutants, is mainly affected by ventilation mode, ventilation performance, ventilation strategies, etc. This paper analyses the status, standards, technologies and products related to residential ventilation and concludes the existing drawbacks in residential ventilation applications in China. Understanding of residential ventilation, and its standards, design methods, technologies, products, also the economy and usability should be given a major consideration to research.

Sheath Material

An oxygen index test was conducted on thirteen different electric cable samples, to determine the limiting oxygen index (i.e., LOI) of each cable composite, its sheath and its insulated wire. A statistical comparative analysis for the data pairs has shown that the LOI of the cable composite correlated sig nificantly well with that of its sheath material whereas it hardly had any sig nificant correlations with that of its insulated wire. This implies that the LOI of a cable composite may be an alternative to that of its sheath material in some cases, though it should be considered that the former tends to be a little higher than the latter. Adoption of the oxygen index test on electric cable com posites instead of that on the sheath coverings could only have merit in simplification and convenience of the sample preparation for the test.

War usually causes damage and suspension of construction work, thus intensified Nazi activity in Poznań brings into focus the ideological functions of architecture. During World War II, the then capital city of Gau Wartheland was the site of numerous urban and architectural projects, as well as many new housing estates and green areas. Moreover, the occupant worked on the conversion of the former imperial castle into a Deutsches Schloss, that is Hitler’s headquarters, which were to express the Third Reich’s dominance over the conquered territories. This was also the function of residential buildings. Many of these projects were given the status of “important to military operations”, hence the architecture should be perceived as a means to secure the territorial gains, and the German settlers as colonists and occupants. The housing estates displayed features of mass construction developed with a view to post-war times and were, therefore, intended to document the ‘endless’ control of the areas incorporated into the Reich. The estates also served to transform these areas in line with Nazi ideology.

A ‘Fareej-in-the-Sky’: Towards A Community-Oriented Design for High-Rise Residential Buildings in The Uae

Most of the native citizens in the UAE live in public or private single-family houses. Given the tremendous cost of developing this type of housing and the inability of providing single-family houses to cover all the current and future needs for public housing, high-rise residential buildings seem to offer an alternative. But the question is; does this type of housing suit the local communities in the UAE, especially in light of the failure of the previous western experiences?. Through addressing this question, the research proposes an approach towards a community-oriented design for high-rise residential buildings in the UAE. The research first investigated the reasons behind the community-relevant shortcomings of the traditional high-rise residential developments in the West. Afterwards, it briefly reviewed the status quo of the community-relevant considerations in the design of the recently built high-rise residential buildings in the UAE, where it has been found that little concern has been devoted to the community needs. In an effort to find an answer to this problem, the research examined four recent design experiences as examples for the current universal efforts to design community-responsive high-rise residential developments. Some conceptual approaches were derived from these experiences that are envisaged to help reach an approach for the case of the UAE. Nonetheless, because of the unique social and cultural traits of the UAE native society one cannot rely on these global conceptual approaches alone. Instead, the research proposes an approach that, while benefiting from the relevant global experiences, is chiefly pivoted on the vertical reconfiguration of the idea of the ‘fareej’ as the smallest unit in the residential urban context both traditionally and in the future official urban plans in the UAE.

<p>[We report the recovery of a wing and the body of a Little Bustard between March 31st and April 7th 2012 in Isiata, San Donà di Piave (VE), it was a female in first winter plumage. Death was almost certainly caused by a collision with electric cables. At the end of 19th century Little Bustard was regular in Veneto, but sightings of this species became progressively scarcer during 20th century, so it was classified as “B40” (species not recorded since 1949) at the suggestion of AERC (Association of European Rarities Committees). The recovery of the corpse in this note is the 4th sighting in Veneto in last 50 years, and we know of 2 additional observations. Between 1950 and the present day there have been 10 regional sightings, so we suggest changing the status of this species in the Veneto to “A30”, according to AERC.]</p><p> </p>

This paper intends to bring attention of both scientific and general audience to the status quo of the existing, residential building stock in Bosnia and Herzegovina, highlighting its energy savings potential. The research results presented in this text may be applicable on two levels: on a larger scale, the policy makers may use this data in the process of development of strategic and EE measures implementation plans, while, on a smaller scale, the individual users may gain practical insight into the benefits of energy saving measures and implement them in their own households. Moreover, the exposed data may be subject to further evaluations, studies and comparisons, while the presented methodology can be used by other researchers in countries where there have not been research activities on the existing residential buildings stock from the EE perspective.

The present paper focuses on the architectural and constructional features required to ensure that building envelope renovation are safe, functional, and adaptable to the building stock, with particular focus on “plug and play” modular facade construction systems. It presents the design of one such system and how it addresses these issues. The outcome of early-stage functional test with a full-scale mock-up system, as well as its applicability to a real construction project is presented. It is found crucial to obtain high quality information about the status of the existing façade with the use of modern technologies such as topographic surveys or 3D scans and point cloud. Detailed design processes are required to ensure the compatibility of manufacture and installation tolerances, along with anchor systems that deliver flexibility for adjustment, and construction processes adapting standard installation methods to the architectural particularities of each case that may hinder its use or require some modification in each situation. This prefabricated plug and play modular system has been tested by reproducing the holistic methodology and new technologies in the market by means of real demonstrators. When compared to more conventional construction methods, this system achieves savings in a real case of 50% (time), 30% (materials) and 25% (waste), thus achieving significant economic savings.

Since January 1, 2019, Federal Law No.217 dated July 29, 2018 “On the introduction by citizens of gardening and gardening for their own needs and on amending certain legislative acts of the Russian Federation” (hereinafter referred to as Law No.217). Changes that occurred with gardening and dacha plots in connection with the adoption of the new federal law caused a number of problems with its implementation. This law has caused a big resonance among citizens, and among management structures, and among the community of cadastral engineers. Land plots that are located in the dacha and garden associations now fall into the development areas of individual and low-rise residential buildings, blocked residential area development. And houses on these sites can acquire the status of individual houses. In this regard, there will be and will arise many questions and problems with the use and management of territories and the registration of rights to real estate.
