Purpose: Research of interaction between ditch fencing constructions and ground massive in negative temperature period. Methods: Pursuing nature measurements on active construction site and numerical modeling. Data on stress-strain state of “ditch fencing -ground massive” system were obtained; the comparison of experimental data with calculation results were made; the proposal on accounting for additional efforts against frost heave in the system “ditch fencing -ground massive” was formulated. Results: It was established that magnitude of forces of frost heave can be significant that says on the necessity to consider them while engineering of unfastened ditch fencings. It follows according to obtained calculation estimation of frost heave forces effecting fencings that it’s necessary not just to take into account a ground freezing depth but also negative temperature values which at, efforts in ditch fencing constructions can reach the maximum. Practical importance: At comparison of experimental data with retaining wall calculation results, the factors are determined which out of, the loss of bearing capability of spacer system particular elements is possible. There’re also obtained the detailed data on joint work of fencing and ground massive at active construction site in geotechnical conditions of Saint-Petersburg.

The article proposes a mechanism for determining the cost effective alternative for wall structures using the price index to the unit of heat conductivity of the material. This method makes it possible to find the optimum ratio of the required heat conductivity to the cost per square meter of the wall. For this purpose, the variants of wall constructions for low-rise building offered by organizations of the Yekaterinburg city were analyzed. The statistical data of the wall fencing materials using was given, and their main advantages were listed. The software heat engineering calculations for different variants of the wall fencing of the low-rise construction were carried out. During the calculation, the parameter of the heat transfer resistance was determined. To find the ratio of the price index per unit of heat transfer resistance, the cost per square meter of material was calculated and based on that the most cost effective alternative for low-rise construction in the Sverdlovsk region was selected.

Full textAbstract:
This paper examines one aspect of the two-way cultural traffic between London and Padua: how the city of Padua figured in debates about the nature of masculinity in early modern London, especially its theatres. Invariably known primarily for its university—noted by Coryat and Moryson, a tourist attraction for Chaucer, Sidney, and Milton—the name “Padua” became synonymous with “erudition.” While learnedness was in theory a positive quality, the place of learnedness in a declining honor culture and its complex role in constituting masculinity remained a contentious subject. English writers by turns envied or scorned the learning acquired in Italy, and invocations of Padua and its link to rapier fencing resulted in a series of contradictory figures in the drama of Shakespeare and Webster: doctors, pedants, enlightened philosophers, lovers, murderers for hire.

.When building buildings and structures on unstable slopes, it becomes necessary to develop geotechnical technologies that ensure their stability. In addition, geotechnical techniques should be developed to ensure the safe operation of existing facilities built on them. Therefore, the main purpose of the work is to study one of the geotechnical technologies to ensure the stability of the fence fencing. As a rule, the opening of any foundation pit entails the emergence of additional efforts reducing the stability of the slopes. The task of ensuring the stability of the pit walls together with the loads on its bumps, as well as the general stability of the slope as a whole, is an urgent task of modern geotechnical construction. It is established that the structural solutions of the buried structures represent a special auxiliary containment structure, fence constructions, ground anchors that are arranged after the first stage of the excavation.

Using data from the US Customs and Border Protection and novel data on border fencing, we examine how the construction of border fencing under the Secure Fence Act influenced crossing decisions and the likelihood of migrant deaths. Apprehension data suggest that fence construction induced migrants to cross in unfenced sectors. Meanwhile, the average death rate rose nearly threefold in the sectors where the fence was not built. These results support our hypotheses that fence construction induced some migrants to cross in unfenced sectors, while others were diverted to cross in more dangerous locations within fenced sectors.

He who possesses information owns the world. This statement is becoming more relevant every day. It is information that has become a tool for modern management and development. Therefore, the role of information technology is also constantly growing along with the risk of their malicious use. Attackers use all possible methods and means of technical intelligence to use potentially possible and create new types of information leakage channels to intercept it. object of information activities. Such oscillations caused by a certain speech (acoustic) signal can be intercepted by means of long-range intelligence. Most often, a laser microphone is used as such. The essence of its action is to emit a laser on the surface of the selected OID, which circulates a speech signal that creates sound vibrations on this surface. The movement of the surface leads to the modulation of the wave by phase, which is manifested in the variable nature of the sound signal Doppler shift of the frequency of the received signal. Often, such a surface is the glass of the windows, which reflects the beam to the receiver, to which is connected a detector that can reproduce the sound from the OID. This study aims to study the dependence of the laser microphone on such factors as: the location of the radiation source and the beam receiver from the membrane; membrane surface material; receiver type; materials of fencing constructions OID. The goal is to create a stand to demonstrate the operation of a laser microphone. The research process is carried out on a smaller scale, which is why an improvised room in the form of a cardboard box was chosen as the OID. Available tools were used to reproduce the operation of the laser microphone, so a laser pointer was chosen as the illuminator, and devices such as a solar panel, a light sensor and a signal amplifier microphone were used as the receiver. The study of the influence of selected factors was performed by measuring the voltage and volume of the acoustic signal using a multimeter and a certified program on the tablet, respectively.

Since the Fourth Industrial Revolution, existing manpower-centric manufacture has been shifting towards technology and data-centric production in all areas of society. The construction sector is also facing a new paradigm called smart construction with a clear purpose of improving productivity and securing safety by applying site management using information and communications technology (ICT). This study aims to develop a framework for earthwork process digitalization based on images acquired by using the unmanned aerial system (UAS). The entire framework includes precise UAS data acquisition, cut-and-fill volume estimation, cross-section drawing, and geo-fencing generation. To this end, homogeneous time-series drone image data were obtained from active road construction sites under earthwork. The developed system was able to generate precise 3D topographical models and estimate cut-and-fill volume changes. In addition, the proposed framework generated cross-sectional views of each area of interest throughout the construction stages and finally created geo-fencing to assist the safe operation of heavy equipment. We expect that the proposed framework can contribute to smart construction areas by automating the process of digitizing earthwork progress.

Full textAbstract:
The ever-growing pace of road construction worldwide has become a serious concern for wildlife and natural habitats, resulting in habitat fragmentation and increasing wildlife road fatalities. For amphibians, which are undergoing population declines worldwide, mitigation measures such as road under-passages linked to amphibian-proof fencing may be an effective conservation tool, aiming to reconnect natural habitats and reduce wildlife fatalities. This study assessed the efficacy of road tunnels in a recently developed area by Frankfield Loch, Stepps, North Lanarkshire. Three amphibian tunnels, plus fencing, were put in place during 2010 following the construction of a road in 2006 which separated the loch from a substantial area of marshland, including ponds. In 2015 and 2016, we used custom-made time-lapse cameras within the tunnels to automatically monitor amphibian movements and conducted frog spawn surveys. Numbers of common frogs (Rana temporaria), common toads (Bufo bufo) and newts (Lissotriton spp.) using the tunnels were substantial in both years, though the number of toads decreased significantly between years. We found many frog spawn clumps in the marsh ponds, but rather fewer in the loch. A period of road repair in 2015 was linked with both road mortalities and a change in the pattern of tunnel usage. Additionally, amphibians showed a daily cycle of activity, with nocturnal movements most common. These results indicate important connectivity and usage of both the marsh and the loch, and suggest that this can be effectively sustained through the proper maintenance of tunnels and fencing, which also minimises road mortalities. It remains unknown, however, what proportion of the population crosses the road via the tunnels and how that compares with movements prior to road construction.

Full textAbstract:
Context Reducing road mortality is essential to reptile conservation in regions with dense road networks. The Georgian Bay, Ontario population of the eastern massasauga rattlesnake (Sistrurus catenatus) is designated as Threatened, in part because of high road mortality. In Killbear Provincial Park, four ecopassages and barrier fencing were constructed along three busy park roads to reduce road mortality of massasaugas. Aim Although mitigation of road mortality has been widely recommended and in some instances implemented for reptiles, effectiveness of mitigation efforts is often inadequately evaluated. The goals of our study were to use long-term data to quantify the effectiveness of ecopassages and barrier fencing in reducing massasauga fatalities on roads, and to evaluate the potential of these structures to serve as movement corridors for individual snakes. Methods We used five approaches to assess the overall efficacy of mitigation efforts: (1) comparison of pre- and post-mitigation road mortality; (2) camera traps in ecopassages to document massasauga and predator presence; (3) automated tag readers in ecopassage entrances to detect PIT-tagged individuals; (4) an experiment to assess massasauga willingness to enter and travel through ecopassages; and (5) measurement of temperature fluctuations in ecopassages to assess thermal suitability for massasaugas. Key results We found a significant decrease in road mortality of massasaugas on stretches of park roads associated with ecopassages and barrier fencing post construction. Automated tag readers and cameras detected the presence of massasaugas and other animals within the ecopassages, and experimental data showed that massasaugas willingly entered, and in some cases crossed through, ecopassages. Conclusion Our evaluation of mitigation structures determined that they successfully reduce road mortality and provide potential movement corridors between bisected habitats, provided that intense maintenance of the fencing is conducted yearly. We also demonstrated the need to utilise a combination of multiple post-monitoring methods to effectively evaluate mitigation structures. Implications This study provides a template for construction of similar mitigation in other key locations where reptile road mortality occurs.

This paper examines the use of predator fences for conservation in Australia. It argues that these major infrastructures for enclosure act as a form of ‘provocative containment’ in which particular forms of nature are not simply protected but made to happen. The primary focus is Newhaven, a property in remote central Australia managed by the Australian Wildlife Conservancy, a non-profit organization with the biggest estate of privately managed land for conservation in the nation. At Newhaven, the first stage of an ambitious and expensive predator fencing programme has recently been completed, with a second phase under construction that will see the property become the site of the largest feral cat-free enclosure on the planet. In analysing this significant material infrastructure, and the practices and discourses that the Australian Wildlife Conservancy deploys to both justify and attract funding for it, it is possible to see a new conceptualization of conservation emerging in which nature is not simply offered sanctuary but actively stimulated and simulated. The Newhaven fence is much more than a passive material boundary between desired and undesired life. It is a reality-generating device with complex and contradictory biopolitical effects. The concept of provocation highlights how the fence emerges as a deliberate intervention into the dynamics of life. We examine how this is done in four distinct ways: through the sociotechnical design and construction of the fence as ‘cat-proof’, by enrolling Indigenous labour and tracking skills to kill cats, through the use of ecological surveys and baselines to make some life calculable, and via the translocation of species in order to allow them to be both protected and flourish. Each of these practices is essential to making new natures at Newhaven through the complex dynamics of provocation and containment. The issue is: what sort of nature?

In the paper the research results of light-weight masonry mortars with hollow glass microspheres (HGMS) and antifreeze admixtures (AFA) for masonry walling of the efficient small items at the low temperatures are given. One has chosen the antifreeze admixtures for the mortars and their rate has been justified. The main properties of the masonry mortars with HGMS and the antifreeze admixtures have been determined. The standard research methods are used. Main attention was paid to the analysis of strength of the mortar with HGMS and the antifreeze admixtures formed at the positive and negative temperatures. The optimal mixtures for the temperature down to 10 °C were developed. A priority direction of development of construction science currently is energy saving and the improvement of energy efficiency of buildings and structures. A part of the solution to this problem is the development of efficient building materials and fencing structures. The use of multi-layer fencing structures is known to lead to a decrease in the coefficient of their thermal uniformity [. In this regard, the most promising is the development of single-wall exterior fencing structures, which answer the requirements of the standards for thermal protection. However, single-wall fencing structures answering the requirements for thermal protection must have an average density value not greater than 500 kg/m3. The materials from cellular concrete, polystyrene concrete, foam ceramics concrete and others satisfy the aforesaid requirements. The monolith unity of similar structures is provided through the use of mortars on the basis of mineral, mineral-and-polymer and polymer binders [2-. Such mortars with high average density and a high coefficient of thermal conductivity are the bridges of cold in the construction; they do not provide the thermal homogeneity of the fencing structure and reduce its thermal resistance. A solution to this problem is the use of light-weight masonry mortars (warm mortars). Such mortars with traditional light-weight fillers (e.g. expanded perlite and vermiculite mortar sands) have an increased water requirement, and, as a consequence, the extremely low strength value. Recently, hollow glass (HGMS) or ceramics (CMS) microspheres are used as light-weight fillers for masonry mortars [. Thus, in [ the scientific principles of the use of such compositions with HGMS have been developed. The masonry mortar has been obtained with the following properties: average density of dried mortar is 450 kg/m3 with a coefficient of thermal conductivity equal to 0.17 W/m·°C and a compressive strength equal to 3.2 MPa at the age of 28 days, water-retention capacity over 90% and with optimal technological and rheological characteristics [.

Abstract The Loess Plateau is one of the most erodible areas in the world, and numerous conservation measures have been implemented to control severe soil erosion. Better understanding of the changes in runoff and their influencing factors is required. A vector autoregression (VAR) model was used to simulate the dynamic relationship between runoff and six factors (precipitation, terraces, afforestation, grassing, check dams' construction, and grazing fencing) based on precipitation, runoff, and controlling measures of the Tuwei River basin in the middle reaches of the Yellow River during 1959–2012. Results showed that response of runoff usually lagged behind precipitation and the implementation of soil and water conservation measures. The annual runoff has no response to the increase of each measure area at the first year, but has varying degrees of response from the second year onward. Moreover, the same measure has different effects on runoff in different periods. The contribution of the factors that affect the annual runoff varied in the order of grazing fencing hillside < grassing < check dams' construction field < afforestation < precipitation < terraces. In the long term, the contribution of soil and water conservation measures would be greater than 70% in the fluctuation of annual runoff.

The use of glass fencing structures - panoramic windows in the residential segment of modern city development is investigated. The peculiarities of the use of panoramic windows in the residential segment of the region are determined. An analysis of scientific publications in magazines with the impact - a factor and the approaches to increasing the energy efficiency of the thermal insulation shell of the building with glass elements of the facade are determined. The advantages and disadvantages of the use of panoramic windows in terms of heat engineering properties of a fencing structure are outlined. It is determined that according to the normative method of calculating the given thermal resistance, there may be a significant difference in calculating the entire facade and design for one room. To confirm the comparative calculation, which resulted in the resulting thermal resistance for a fragment of the facade (where there are two windows) is 3,3 m2 K / W (corresponding to the requirements of the normative value), and when calculating the fragment of this facade of a separate room with a panoramic window with a panoramic window. The result of the given thermal resistance is 2,6 m2 K / W (which is significantly lower than the normative value). The factors influencing the technical state of panoramic windows are outlined and lead to a decrease in the heat-insulating characteristics of the enclosing structures of the building; As well as measures and organizational and technical solutions, which allows the use of panoramic windows in modern housing construction. It is proposed for the heating of premises with panoramic windows of the scheme of placement of heating systems, namely: installation of vertical radiators on the side of the double-glazed windows; Planting a convector-type floor battery; arrangement of the system "Warm floor" and combined systems; internally floor convectors; infrared heaters; Installing slit or plinth convectors in the floor below the window, on the wall or ceiling. Recommended investors of new apartments to pay attention not only to the facade of the facade in the design decisions of external enclosures of buildings with the use of panoramic windows, as well as technical solutions of windows, ventilation and heating systems, which significantly affect the energy efficiency of the future apartment.

Full textAbstract:
The varying reasons are outlined for needing to control the movements or otherwise manage a wide range of African animal wildlife species by means of fencing. In all cases there is an underlying conflict of interest between people and animals — principally the larger mammals. Fencing is seen as the most powerful tool in this process of land-use division, and high expectations of fences are held by people who are adversely affected by wildlife activities and similarly by many conservationists. To date the main determinants in the siting and construction of fences have been political pressure or the availability of funds; wildlife fencing is perhaps the only factor having a substantial influence on ecosystems and animal populations that has remained virtually devoid of any serious input of ecological knowledge, of systematic investigation, or of environmental legislation.The wild species requiring management are many and varied in individual size, group size, and dispersal patterns; they also exhibit an array of special behaviours when confronted with a barrier. This means that any barrier will come under very variable levels and types of challenge, and that the effects of it on the biology of both target and non-target species must be carefully considered.Research on the behaviour of animals at fences has been limited, being mostly confined to domestic species or non-African wildlife. Certainly, very little systematic investigation has been carried out to determine whether fences have achieved their objectives or been economically justified, and to what extent they have caused environmental side-effects on the population dynamics of animals or the disturbance of plant communities.Current evidence suggests that electric or power fences are an increasingly efficient way of managing wild mammals and that fencing programmes should become more deflecting than encircling. Fences create ‘hard edges’ between dissimilar forms of land-use and cause long-term inflexibility that limits planning and forecloses options. As the pressure for land becomes more and more acute, the control of wildlife with the help of fences needs to develop into a specialized field of its own, based on sounder ecological, sociological, and economic, principles than hitherto, within the expanding scope of adaptive wildlife management.

Urban motor transport complex engineering structures, the construction of which is carried out for a long time, and the cost is often tunnels of structures. Despite this, urban tunnels remain in demand as a means of solving transport problems, especially for large cities, in areas with dense urban development or an established architectural appearance, the violation of which is unacceptable. The construction of tunnels makes it possible to increase the throughput of highways, especially in places of large intersections, one of the diverting high-intensity transit traffic flows underground, making them invisible on the surface and thus not disrupting the existing historical appearance of the area.

Full textAbstract:
Invasive predator control is often critical to improving the nesting success of endangered birds, but methods of control vary in cost and effectiveness. Poison-baiting or trapping and removal are relatively low-cost, but may have secondary impacts on non-target species, and may not completely exclude mammals from nesting areas. Mammal-exclusion fencing has a substantial up-front cost, but due to cost savings over the lifetime of the structure and the complete exclusion of mammalian predators, this option is increasingly being utilized to protect threatened species such as ground-nesting seabirds. However, non-mammalian predators are not excluded by these fences and may continue to impact nesting success, particularly in cases where the fence is designed for the protection of waterbirds, open to an estuary or wetland on one side. Thus, there remains a research gap regarding the potential gains in waterbird nesting success from the implementation of mammal-exclusion fencing in estuarine systems. In this study, we compared the nesting success of endangered Hawaiian Stilts (Ae‘o; Himantopus mexicanus knudseni) within a mammal-exclusion fence to that of breeding pairs in a nearby wetland where trapping was the sole means for removing invasive mammals. We predicted success would be greater for breeding pairs inside the exclusion fence and the hatchlings inside the enclosure would spend more time in the nesting area than hatchlings at the unfenced site. During a single breeding season following construction of a mammal-exclusion fence, we used motion-activated game cameras to monitor nests at two sites, one site with mammal-exclusion fencing and one site without. Clutch sizes and hatch rates were significantly greater at the fenced site than the unfenced site, but time spent by chicks in the nesting area did not differ between sites. These results add to the mounting body of evidence that demonstrates the effectiveness of mammal-exclusion fencing in protecting endangered birds and suggests it can aid endangered Hawaiian waterbirds toward recovery. These results also suggest that the single greatest predatory threat to the Hawaiian Stilt may be invasive mammals, despite a host of known non-mammalian predators including birds, crabs, turtles, and bullfrogs, as the complete exclusion of mammals resulted in significant gains in nesting success. As additional fences are built, future studies are necessary to compare nesting success among multiple sites and across multiple seasons to determine potential gains in fledging success and recruitment.

Full textAbstract:
Background: Providing safe and adequate Water, Sanitation and Hygiene (WASH) services in response to emergencies is a major problem. Globally, few studies have investigated the bacteriological quality of drinking water at the IDP sites. Therefore, the objective of this study was to evaluate the bacteriological quality of drinking water and associated factors at the IDP sites of Gedeo zone. Methods: A cross-sectional study was conducted on 213 water samples collected from November to December 2018. The membrane filter technique was used to retain bacteria and lauryl sulphate broth media was used to detect faecal coliforms. After incubation of 14 hours at 44°C, faecal coliforms with yellow colonies were counted and expressed in terms of CFU/100 ml of water. The data were entered into Epi data version 3.1 and exported to STATA version 14 for analysis. Binary logistic regression analysis with 95%CI and P ⩽ .05 was used to identify factors associated with an outcome variable. Results: Out of 213 water samples collected, 107 (50.2%) samples were tested positive for faecal coliforms. The presence of latrines in uphill (AOR: 6.7, 95%CI: 1.0-42.9), other sources of pollution (AOR: 5.0, 95%CI: 1.1-22.3), inadequate fencing (AOR: 7.1, 95%CI: 1.3-40.2) and lack of diversion ditch (AOR: 6.3, 95%CI: 1.0-37.6) were factors significantly associated with faecal contamination of springs. Dug wells that had a latrine within 10 m (AOR: 11.4, 95%CI: 1.8-72.1), other pollution sources within 10 m (AOR: 7.9, 95%CI: 1.9-32.4), inadequate fencing (AOR: 2.8, 95%CI: 1.0-7.9), drawing water using a bucket with rope (AOR: 7.3, 95%CI: 1.6-33.4) and unsanitary well cover (AOR: 3.4, 95%CI: 1.1-10.4) were factors significantly associated with faecal contamination of wells. Conclusions: The majority of the water sources in internally displaced people sites were tested positive for faecal coliforms. The presence of latrine in uphill, other sources of pollution, inadequate fencing, lack of diversion ditch, drawing water using a bucket with rope and unsanitary well cover were factors associated with the presence of faecal coliforms. Therefore, adequate fencing, proper diversion ditch construction and hygiene promotion should be done to protect water sources from faecal contamination. Furthermore, latrines and other point sources of contamination should be located at least 10 m away or at a lower elevation from water sources.

Full textAbstract:
Conservation and transport decision makers must deal with many competing criteria in order to find the optimal connectivity of habitat patches in order to maximize organisms’ ability to traverse the landscape successfully. Thus, there is an increasing interest in prioritization of habitat patches by their contribution to overall landscape connectivity. Many different indices can be used to quantify structural and functional landscape connectivity. However, landscape connectivity indices alone do not clearly define conservation priorities for habitat patches. In this study priority values for each available habitat patch were calculated using multiple criteria spatial decision support techniques. As criteria for prioritization, spatial graph-based element properties (habitat patch size, number of corridors connected to a habitat patch, etc.) were characterized for each habitat patch. Graph-based connectivity rules for each habitat patch within a landscape (in conjunction with largest patch size, maximum number of corridors with a minimum length connected to a habitat patch, etc.) were defined and applied. Each criterion’s importance was assessed. Criteria-based ranking of habitat patches within a graph better indicated exact critical habitat patches than connectivity index alone, especially when changes in network occur. Simulations in the case study of Lithuania showed that barriers (road fences to keep animals off the road) without prompt establishment of animal crossings may realign complexes of an ecological networks by reducing the importance of adjacent and increasing the importance of more distant patches. Such distant patches may become essential, and can sometimes be the only elements preserving the realigned ecological network.

This paper reports a feasibility study which addressed the development of a new, advanced system mainly devoted to automatic real‐time health and safety management on construction sites. The preliminary analyses and experiments described in this paper concern two of the most important functionalities which must be included in the system's final release. The first functionality consists in real‐time position‐tracking of workers involved on construction sites and the second ‐ in a software tool for the prevention of non‐authorized access to dangerous zones. This research step is part of a vaster, ongoing research project, addressing the development of a new generation of advanced construction management systems which allow real‐time monitoring and coordination of tasks, automatic health and safety management, on‐site delivery of technical information and the capture of “as‐built” documentation. This paper focuses mainly on the development of a reliable methodology for real‐time monitoring of the position of both workers and equipment in outdoor construction sites by applying Ultra Wide Band (UWB) based technologies. This positioning system was then interfaced with a software tool which performs virtual fencing of pre‐selected, dangerous areas. Guidelines for the design of the receivers’ topology will be addressed and the results of measurements recorded on a typical medium‐sized block of flats, during different phases of the construction progress will be summed up. Finally, the preliminary experimental results obtained by the virtual fencing application tool will be presented and used to plan future research objectives.

the most important direction of resource saving in construction is the widespread use of secondary material resources, which are waste products. The use of secondary products of industry as raw materials for the production of various building materials is very important, because it provides production with rich sources of cheap and, often, already prepared raw materials; lead to lower costs for the production of some building materials, and therefore saves capital investments intended for the construction of buildings and structures; release large areas of land and reduce the impact on the environment. The article deals with heat-insulating and structural-heat-insulating materials, with partial replacement of components by ash-slag waste (ASW): lightweight concretes with broken glass and concretes modified with sulfur. Properties of concretes modified with sulfur are investigated: compressive strength, density and thermal conductivity. In accordance with the obtained properties, a comparative characteristics of the received materials with existing building materials was carried out: sulfur modified concrete and lightweight concrete; lightweight concrete using broken glass and claydite-concrete. Thermophysical calculation of multilayer hencing is made. In each of the options, one of the following materials was selected as a structural and heat-insulating material: lightweight concrete using broken glass and sulfur modified concrete. Also, for each type of hencing, the necessary heat-insulating and structural materials were selected. In the economic part, the cost of the raw materials necessary to obtain 1 m3 of the investigated materials and the cost of 1 m3 of multilayer hencing, which includes the investigated concrete, are calculated.

Full textAbstract:
The catastrophic declines and extinctions of a unique Gondwana-derived Australian mammalian fauna is a wildlife tragedy of epic proportions that remains to be played out. Four alien species in particular, rabbits (Oryctolagus cuniculus), foxes (Vulpes vulpes), feral cats (Felis catus) and cane toads (Rhinella marina) are recognised as ongoing threats, but protective control protocols consist of holding actions that currently require never-ending ecosystem subsidies (typically, culling and fencing). Recent revolutionary developments in cell biology and gene engineering – the CRISPR invention – has enabled the construction of gene drives that offer the prospect of controlling these species more efficiently indeed, even the possibility of extirpating these species from Australia. The conservation potential of these new technologies is described and recommendations are made.

In 1957 the State of North Carolina, in cooperation with the Beach Erosion Board and the Wilmington District of the Corps of Engineers undertook an experimental dune building study on the Outer Banks of North Carolina. The experimental study consists of the construction of various types and arrangements of sand fences to determine the fence type and arrangement most effective in building a dune by trapping windblown sand. Four miles of experimental fencing were constructed in 1960. During the following year, four sets of profiles were made to determine the sand accumulation of the fences and a rather intermittent wind record was made in the area. The performance of the various fence types and arrangements has been compared and some conclusions have been reached concerning the best fence type and arrangement.

Full textAbstract:
Road ecology has traditionally focused on the impact of in-situ and functional roads on wildlife. However, road construction also poses a major, yet understudied, threat and the implications for key aspects of animal behaviour are unknown. Badgers (Meles meles) have been implicated in the transmission of tuberculosis to cattle. There are concerns that environmental disturbances, including major road construction, can disrupt badger territoriality, promoting the spread of the disease to cattle. To address these knowledge gaps the ranging behaviour of a medium-density Irish badger population was monitored using GPS-tracking collars before, during, and after a major road realignment project that bisected the study area. We estimated badgers’ home range sizes, nightly distances travelled, and the distance and frequency of extra-territorial excursions during each phase of the study and quantified any changes to these parameters. We show that road construction had a very limited effect on ranging behaviour. A small increase in nightly distance during road construction did not translate into an increase in home range size, nor an increase in the distance or frequency of extra-territorial excursions during road construction. In addition, suitable mitigation measures to prevent badger deaths appeared to ensure that normal patterns of ranging behaviour continued once the new road was in place. We recommend that continuous badger-proof fencing be placed along the entire length of new major roads, in combination with appropriately sited underpasses. Our analysis supports the view that road construction did not cause badgers to change their ranging behaviour in ways likely to increase the spread of tuberculosis.

The investigations of thermal and technical features of enveloping structures show that at the present time the structures of outer walls with hinged ventilated facades are the most energy efficient. The facades with air space are widely used both in residential and in public buildings. In the recent years the problems related to energy efficient enveloping structures are being actively investigated. The problems of modern Russian and foreign energy-efficient facade systems, their technical and structural solutions and the main methods of their installation are reviewed in the article. The methods of solving the tasks of research are proposed and the obtained results are described. The development of organizational and technological solutions for sealing of joints of front panels during installation of ventilated facades by pre-assembly method was the basis of the method of solving of the problem. The obtained data together with the developed structural and technological solutions may become the base for the development of technical rules and regulations.

La Noble Science des Joueurs d’Espée (originally La Noble Science des Ioueurs Despee) is a fight book printed in 1538 by Willem Vorsterman, a local printer in Antwerp. Printed in several exemplars, the book is the French translation of a German fencing treatise written by Andre Paurnfeindt, which itself was first published in Vienna in 1516. The study of Vorsterman’s edition shows several errors were made in recreating Paurnfeindt’s work, including inversions of image and text, which have the potential to alter the transmission of the text’s martial knowledge. This raises the question of Vorsterman's commercial intentions when editing and printing this fight book, especially regarding the flourishing printing business in sixteenth-century Flanders. This paper aims to describe the differences in construction between Vorsterman and Pauernfeindt’s treatises in the context of both printing and martial cultures in Antwerp and the surrounding region.

Growing vegetables in cultivation facilities can significantly increase the yield of products compared to open ground. Information data on greenhouses offered by producers for farms is summarized. The main types of farm greenhouses are identified, and they are compared for possible heat losses during the cold period of the year. It is established that with an equal building area, the area of enclosing structures of multi-span greenhouses is less than that of single-span frame and arch type. The formula for the minimum coefficient of fencing for a multi-span greenhouse, which provides a minimum of energy costs during the heating period, is derived. The structural scheme of the steel frame of a multi-span greenhouse of construction production from rolled profiles is proposed. It allows to significantly reduce the cost of construction of the structure in comparison with the cost indicators of greenhouses of factory delivery. The dependences of steel consumption for structural elements of the frame as a function of load and its construction parameters are obtained. Based on the obtained dependencies, the rational values of the span and step of the block greenhouse racks for snow loads specified in the building design standards of greenhouses are established. For rational values of planning parameters of the cultivation structure, specific indicators of steel consumption and cost per greenhouse frame are given.

Full textAbstract:
In this paper, we consider the influence of the conditions for fixing a wavy plate lying on an elastic foundation on its stressed-deformed state. The profiled plates are widely used in construction practice as fencing structures, for siding works, for roofing and others. The stress-strain state of the wavy plates varies depending on geometry, materials mechanical properties, foundation characteristics and boundary condition. Steel with polymer coatings, which make the sheets a decorative material, is increasingly used in individual and low-rise buildings. The elastic foundation is considered as Winkler base, so we suppose that the reaction of the base is directly proportional to the deflection of the plate at each point. The Bubnov-Galerkin method is used to determine the stress-strain state of the plate. To solve the problem, we use special orthogonal Legendre polynomials satisfying the boundary conditions: simply supported and clamped edges. The results of the calculations were compared for different types of fixation.

The development of effective protecting structures is currently one of the most popular areas in the construction industry. Masonry made of aerated concrete blocks is used in conditions of ensuring energy efficiency and environmental safety in the construction of civil buildings as enclosing structures. It has high thermal protection properties. The issue of filling through seams of aerated concrete masonry is acute, since adhesive and cement-sand mortars in masonry have low thermal conductivity and are temperature bridges. The authors have developed a two-row energy-efficient wall masonry made of aerated concrete blocks using polyurethane glue as a filler for through and dressing joints. The article discusses the effect of horizontal through joints made of cement-sand mortar and blocking of blocks on the resistance to heat transfer of masonry from aerated concrete blocks. In addition, it presents a study of the reduced resistance to heat transfer of the enclosing structure, taking into account heat-conducting inclusions, presented in the form of a traditional two-row aerated concrete masonry through a row, made on a thin-layer adhesive solution, as well as the masonry developed by the authors. It is concluded that the energy efficiency of the developed wall fencing is ensured due to the increased thermal homogeneity of the masonry.

Full textAbstract:
The impact of roads on local biodiversity is a major issue associated with urbanisation. A major arterial road in the southern suburbs of Brisbane, south-east Queensland, was upgraded in 2004–05 from two to four lanes. In an attempt to minimise the impact of the larger road on local wildlife populations, a range of fauna crossing structures were constructed at the site. Monitoring of road-kill was undertaken for 4 months before construction and after the completion of construction. Assessment of the use of two underpasses and a large overpass (‘land-bridge’) started 6 months after construction using sand tracking in underpasses and scat sampling on the land-bridge. An initial 26-week period of intensive monitoring was undertaken from August 2005 to February 2006 followed by monthly monitoring from June 2006 to June 2007. On average, 1–5 tracks per day were detected in the underpasses at the start of the survey, increasing steadily to ~42 tracks per day by February 2006. The monthly survey showed regular use of the underpasses by a wide range of species and species-groups, the most abundant being ‘rodents’, most likely Rattus species, both native and introduced. The land-bridge was also used continuously by three species of macropod (red-necked wallaby, Macropus rufogriseus; swamp wallaby, Wallabia bicolor; and eastern grey kangaroo, Macropus giganteus) with brown hare (Lepus capensis) becoming increasingly common in summer 2006. The exclusion fencing was extremely effective in preventing most road-kill, at least of larger species, except following human-related breaches in the fence.
