Full textAbstract:
Aizhai Bridge is a stiffening steel truss girder suspension bridge and the main bridge consists of three spans of 242m+1176m+116m. It flies over Dehang Canyon, which is cliffy and steep, the depth between the designed elevation and the ground is 355 meters. In order to overcome the problems happened during the transportation, a new construction plan for the erection of steel truss girder is developed, combining the lifting technology with the cable-tracking transportation. Simply speaking, main cables and hangers are used as bearing structure, the track cables hanged on the hangers are used as transportation track. The transport vehicles system run along the tracking cables to deliver the steel truss girder, and the deck unit erecting system do the lifting job. In this paper, the scale model experiment and full scale model test of the track-cable transferring system are introduced, the design and test of erection gantry for deck unit are described. Finally, the engineering application of the track-cable erecting system is described. The results of experiment and engineering application show that the transportation and erection work of steel truss girder can quickly be completed by using the new construction plan. It is safe and economic solution, and has very broad prospect and practical value for the construction of suspension bridge and arch bridge.

Full textAbstract:
Étienne-Jules Marey was born in Beaune, France, on March 5, 1830, to a wine merchant and a teacher. To satisfy his father's wishes, he decided to study medicine, attending the Faculty of Medicine in Paris. Marey's fascination with both animals and mechanics inspired him to concentrate on physiology, and it was during his investigations of this field that he became involved in optics.Ignazio Porro's primary contribution to optics was an innovative prism image erecting system that is commonly used in binoculars and stereomicroscopes, though he also invented and improved a number of other scientific instruments. Today Porro is often considered to have been ahead of his time in many ways. The Italian engineer received little acclaim or monetary compensation for his innovative devices, which only came to be fully appreciated and widely utilized after his death. In fact, when Ernst Abbe attempted to patent binoculars containing his own prism erecting system in 1893, the physicist was very surprised to find that someone else had invented and patented the design decades earlier. Despite his own intense work in the field of optics, Abbe had never heard of the inventor, a telling indication of Porro's difficulties.

Full textAbstract:
Transnational migration flows have revitalised the interest in ethnicity in social sciences. The ethnic boundary approach (Barth, Wimmer) argues for a non-essentialist understanding of ethnicity and calls for detecting the factors that turn migrants into ethnic minorities. Based on ethnographic fieldwork among Dutch police officers between 2008 and 2013, this article presents three factors that together constitute a structural framework that produces events of ethnic boundary construction (salient ethnic identity plus ethnic closure) between migrant and non-migrant officers: (1) ethnicised precarity; (2) ethnic conflicts triggered by the ethnicising discourse in Dutch media and politics on migrants and migration; and (3) the quasi-therapeutic management style applied in the police organisation. It further calls for a differentiated understanding of migrants’ precarity, questions explanations of ethnic closure in terms of stereotypes and critically scrutinises socio-psychological approaches of ethnicity and diversity management.

Full textAbstract:
This study adopts the flow shop concept used in industrial production to schedule repetitive non-linear construction projects, where specialized groups of workers execute processes in work zones (buildings) in a predefined order common to all groups. This problem is characteristic of construction projects that involve erecting multiple buildings. As the duration of the project heavily depends upon the sequence of the work zones, this study aims at providing a model and a practical approach for finding the optimal solution that assures the shortest duration of the project, allows the contractor to complete particular work zones (buildings) as soon as possible (without idle time), and conforms to a predefined sequence of work zone completion. This last constraint may arise from the client’s requirements or physical conditions of the project and has not been addressed by existing scheduling methods. Reducing the duration of the entire project brings the benefit of lower indirect costs and, if accompanied by a reduced duration of completing particular buildings (i.e., work zones), may also provide the opportunity to sell project deliverables sooner, thus improving the economic efficiency of the project. In search of optimal schedules, the authors apply the algorithms of Minimum Hamiltonian Cycle/Asymmetric Traveling Salesman Problem (ATSP).

Full textAbstract:
Technologies of construction ofLow-rise buildings of various design schemes are considered.
Particular attention is paid to the technologies of erecting blocked houses (townhouses), cottages and other low-rise buildings.
As a basis of technologies, new design solutions and mechanization means are adopted, which ensure a reduction in the duration of work and material consumption in the construction of low-rise buildings. Thus, the article shows that the transition from tape foundations to foundation slabs reduces the duration of work on the foundation in 2,5-3,0 times.
The technological features of the erection of the blocked houses of the wall system and the prefabricated monolithic system are considered. It is shown that irrespective of the constructive scheme, the external walls according to thermotechnical indices are made of gas silicate blocks with a density of D 350-400 and a thickness of 450 mm, which makes it possible to reduce the work complexity in 2,0-2,5 times compared to a brick or three-layer masonry. It is shown that the use of gas silicate blocks allows the construction of buildings up to three floors in various climatic zones.
It is shown that an increase in the production of gas silicate blocks is associated with the economic benefit of their use. In addition, the statistics on heat consumption in townhouses testify to the use of gas-silicate blocks, which are twicelower than city-wide ones, and thelabor intensity of the gas-silicate blocks is five times lower than the brickwork and cheaper by 15-20%.

Full textAbstract:
Purpose This paper aims to conceptualize brand repulsion as a specific nuance of brand rejection, highlight the boundary work at play in situations of collective brand repulsion and extract implications for the brands that are at the centre of such situations and to delineate future directions for scholars. Design/methodology/approach The authors’ study of the “I Hate Apple” group on Facebook is grounded in a six-year long naturalistic enquiry designed to capture the boundary work performed by its members. The authors’ sources include netnographic data, online focus groups, observations and personal online correspondence with members and moderators. Findings This study’s findings reveal that certain brands serve the identity work of consumers by allowing them in erecting boundaries based on three major sources of repulsion: anti-fandom, anti-hegemony and anti-marketing. They show that for each type of boundary work, corporate and product brand repulsion seems prevalent. Research limitations/implications This research limits itself to considering the types of boundary work related to brand repulsion as regards a single brand: Apple. Practical implications The study can help managers identify the types(s) of boundary work related to their brand and it provides practical recommendations for these various sources of brand repulsion. It also helps them distinguish between consumer brand repulsion directed against their product and their corporation. Originality/value This study advances knowledge in the field of brand rejection by exploring a specific nuance: brand repulsion. Its close examination of consumer collective practices offers a deeper understanding of the ins and outs of the paradoxical phenomenon of repulsion/attraction for a brand. The cultural lens is used as an original approach to this under-investigated nuance of brand rejection.

Full textAbstract:
The article covers the issue of high-rise buildings (skyscrapers) construction in Russia as the dialogue of artistic image and intellectual idea. The study shows that the professional commitment to skyscrapers erection brings to the foreground the comprehension of magnitude of the notion of “contemporary” in terms of time. It is important from methodical point of view to return to the initial meaning of the notions that provide for adding authentic meaning to the words “suprematism”, “commitment”, “excellence”, “new”, “high”, and other determinants of creativity capable of going beyond “flying geese” development pattern in architectural shaping. It is well known that V.G. Shukhov’s patents of 1896 were widely used in contemporary morphology of shaping. The heritage of Russian Avant Garde of 1910-20ies serves as an inspiration from methodological point of view (it is more and more evident from foreign master’s creative experience). This is why it is important to return, first of all, to comprehension of the author’s version of the notion “suprematism” ascending to Malevich - meaning commitment to excellence and not the “emblem” of preferences in style. The article includes the arguments providing for the capture of the 2010ies and, especially, 2015-17ies as the years of critical changes in history. Russian masters of architecture started as equals the stage of cooperative creative work with foreign architects erecting skyscrapers.

It is considered the construction of the underground part of buildings and structures by "Moscow method", the essence of which is an arranging of pit’s enclosing structure – "wall in ground" in common with the underground part of a building, when pit enclosure is braced in outward thrust with disks of major floors of the underground part of the erecting building, which are connected to each other by a system of spacers, suspensions and racks forming support structure. The positive and negative features of the method are given. The article summarizes the experience of this method, which is advisable to use in construction of the underground part of buildings or structures in cramped urban conditions, provided that the enclosing structure of a pit is "wall in ground". One highlights the stages and gives the main specific features of the method. It is shown that this method leads to a reduction of work costs at the zero cycle, but it increases the duration of work.

Full textAbstract:
This paper made a thorough influencing parameter analysis on the unstressed state and completed state of main cable of self-anchored suspension bridge. The main cable curve, the amount and the action point of the resultant force of main cable on the main saddle were considered as the controlling objectives, the rational completed state of main cable was defined; Wusong bridge in Jilin city was taken as an example, the finite element mode of main cable was created. The unstressed state and the completed state of main cable under different parameters were calculated, and all the results were compared with the reference state, the influences of each parameter deviation on the state of main cable were studied: the self-weight and erection temperature of main cable had little effect on the state of main cable; the length of the mid-span main cable mainly influenced itself line-shape, while the length of the side-span main cable had significant effect on each controlling objective; made the unstressed line-shape of main cable as the controlling condition, the position deviation of the main saddle and back anchorage facet, happened before the main cable erection stage, had little effect on the completed state, but which will have great effect on the completed state when they happened after the main cable erection stage. Engineering example analysis results showed that, the tensile stiffness of main cable and the boom-completed force would have some effect on the completed state of main cable, and the tensile stiffness of main cable and the self-weight of the main beam should be tested before erecting the main cable, in the same time the deviation should be control within the rational limits; recommended that the unstressed shape of main cable should pre-lift, which could counteract the deformation of the main saddle and the back anchorage facet at the completed stage, this conclusion had a strong guiding significance and reference value on the work of constructing the main cable of self-anchored suspension bridge.

Full textAbstract:
Urgency of the floor structures replacement is driven by the program of capital repair of the residential buildings adopted by the government and stipulates replacement of wood coverings by armored concrete floors that enable increase of stability, fire-resistance and cost effectiveness. Wood partitions and other elements of planning made of materials with low fire-resistance are also subject to replacement. It has been shown that the use of void formers allows reducing consumption of concrete, reinforcement, reduces duration of building and energy consumption. Thereby the stability and fire-resistance increase of the buildings under renovation is achieved. Solving these tasks is the objective of the represented work. It is worth noting that when renovating buildings the data about the use of not extractable void formers are absent. The technology development is an author’s initiative. The goal of the investigations consists in analyzing the works of the domestic and foreign scientists that make it possible to assess effectiveness of the technology when erecting buildings of cast in-situ reinforced concrete with the use of void formers. The submitted work has carried out the adaptation of the works performance technology in confined spaces of capital repair. Optimization of the void formers selection has been made, node points of the slabs’ resting on brick walls have been developed, the technology of dismantlement, form work, reinforcing, installation of void formers and concrete pouring has been developed. The complex of the works provides for obtainment of floor structures with the lesser consumption of concrete and reinforcement..

During repair work to the south transept of Gloucester Cathedral carried out in 1979-83, a survey was made of the whole of the south elevation (including the Great South Window, the earliest extant example of the Perpendicular style). Examination of some 5,500 stones revealed that a great number of the original Norman stones had been reused in various positions during a major programme of conservation dated by documentary evidence to 1331-36, which was designed to modernize the poorly lit eastern arm and transepts. The structural problems involved included taking down the south and west walls of the transept to one-third of their original height while keeping the south-west turret intact, and dismantling and re-erecting the high-pitched gable between the two staircase turrets during the insertion of the new window. The structural problems and the solutions adopted are discussed, and a probable building sequence is suggested.

Full textAbstract:
The usage of AAC (Autoclaved Aerated Concrete) blocks for the construction of new masonry structures, particularly low-rise residential buildings, has become very popular in Poland. It provides an uncomplicated erecting method, which is characterized by thin bed joints and unfilled head joins, but at the same time, makes these walls very sensitive to any internal tensile stresses, causing damage with varying intensity. To avoid premature cracking, leading to a brittle failure of existing walls, an external strengthening can be an acceptable and effective solution. Taking into account that AAC units are a natural material, the application of a FRCM system (instead of FRP) is more suitable here. This system uses a mineral-based matrix that provides congenial compatibility with a masonry substrate.This study presents an analysis of the influence of superficial strengthening on the behaviour and deformability of masonry walls made of AAC blocks. A typical glass mesh (most often used in thin external plastering) and mineral mortar dedicated to renovation works are used as strengthening materials. The specimens are strengthened unilaterally (two types) or bilaterally and are subjected to diagonal compression according to the RILEM 76-LUM standard. The consecutive work stages, shear strains and modes of failure are described and discussed.

Full textAbstract:
Estimates indicate that 30 to 70 percent of cast-in-place concrete cost is attributable to the assembly and stripping of formwork. This wide percentage range is partially due to factors that are not well understood with regard to their influence on productivity. The purpose of this paper is to identify the factors that influence formwork productivity and identify a methodology to evaluate productivity data. Two groups of factors were found to have a great effect on formwork productivity: non-measurable factors such as contract document and measurable factors such as engineering design. This paper discusses the effect of both groups of factors on the productivity of vertical formwork. To quantify the effect of the measurable factors on formwork productivity, a case study of the productivity of a crew of carpenters erecting wall formwork for a three-story underground parking structure is presented and analyzed. Data were collected by physically measuring the daily output of vertical formwork erected and the total daily work hours. Key words: formwork, productivity, construction methods.

Full textAbstract:
In their wish to preserve the memory to the compatriots who lost their lives in the Holocaust, the Jewish community in Yugoslavia started erecting monuments to Jewish civil victims and fallen soldiers as early as the first few post-WWII years. The Monument to the Fallen Jewish Soldiers and Victims of Fascism put up in the Sephardi cemetery in Belgrade in 1952, potent with artistic and political significance, stood out from the rest of the monuments of the period. It was dedicated to all the Jews from the Socialist Republic of Serbia who lost their lives in the World War II. The purpose of this article is to analyse the competition for the design of the monument by examining the documents from the Archives of the Jewish Historical Museum in Belgrade, thus making a contribution to the research of the culture of Holocaust remembrance in the Yugoslav Socialism, but also to show artistic, social and ideological aspirations of the time when, after the Cominform schism, Yugoslavia was at political crossroads. By exploring the symbolism and aesthetic values of this work, the research presented in this paper attempts to enhance the understanding of architect Bogdan Bogdanović's early creative efforts.

Full textAbstract:
The use of timber as structural building material is growing and a greater number of firms are looking to enter this raising market. Erecting a complex timber building usually involves combining the work of architects, structural engineers, builders, suppliers and/or supplier–builders, all of them having their own business models. The purpose of this research was to uncover the specific nature of business models in the timber structure building industry. First, a thorough mapping of these business models was undertaken. Second, underlying patterns were uncovered within these models. A triangulation method of secondary data, semi-structured interviews and participant observation was used to allow for an in-depth study of 23 stakeholder business models. The analysis shows that knowledge sharing appears as crucial and may be achieved through sustained collaboration. As a result, collaborative contract procurement modes seem to be the most appropriate for timber construction. Tight relationships with suppliers and supplier–builders also appear as prerequisites. Furthermore, stakeholder partnerships with universities appear common in the field, while prefabrication is increasing in popularity. These findings can be useful to grasp the prevailing business models in this industry given the sustained growth of the timber structure building market.

Full textAbstract:
Dry building mixtures' market analysis demonstrated that construction arrangement experts sometimes do not have enough information or are not aware of the methods enabling them to choose effective dry building mixtures to be used while erecting partitions of plasterboards. Pre-project documentation usually does not specify, which of the mixtures (in most cases called ‘putty’) should be used in certain cases. That results in certain problems at the pre-construction stage as well as at the time of setting and puttying seams of the plasterboard partitions and at the time of preparing the partitions for final finish. There are even more alternatives to be considered while increasing processibility of erection of the whole partition: the same type of putty may be used for setting all layers in order to facilitate the suppliers' work, or firmer putty may be used for the first layers and a different one—for the final layer in order to achieve better quality; setting a seam which is particularly resistant to cracks or confining oneself on a weaker seam, which will be later covered by wall-paper or ceramic tiles, etc. Abundance of alternatives and possibility to put into practice any of them creates quite a great emotional tension. In this case subjective opinion of an employee making the decision becomes determinant. Which of the subjective factors of evaluation are the most important? Questioning of some building-related employees was carried out in order to answer the question. 59 respondents have filled in the questionnaire. Table 4 provides the results of the respondents' determination on the most important factors of putty evaluation and choice. Methods of determining the importance of effectiveness factors are described in detail in certain literature [4, 5, 6, 7]. This article suggests evaluation of the product's usefulness subject to the formula (2) with certain restrictions or following the SAW method (3). The ideal point method (4)—(9) specified in this evaluation model should be used only if special software is available.

The protective effect of physical activity on arteries is not limited to coronary vessels, but extends to the whole arterial system, including arteries, in which endothelial dysfunction and atherosclerotic changes are one of the key factors affecting erectile dysfunction development. The objective of this study was to report whether the endurance training intensity and training-induced chronotropic response are linked with a change in erectile dysfunction intensity in men with ischemic heart disease. A total of 150 men treated for ischemic heart disease, who suffered from erectile dysfunction, were analyzed. The study group consisted of 115 patients who were subjected to a cardiac rehabilitation program. The control group consisted of 35 patients who were not subjected to any cardiac rehabilitation. An IIEF-5 (International Index of Erectile Function) questionnaire was used for determining erectile dysfunction before and after cardiac rehabilitation. Cardiac training intensity was objectified by parameters describing work of endurance training. The mean initial intensity of erectile dysfunction in the study group was 12.46 ± 6.01 (95% confidence interval [CI] = 11.35-13.57). Final erectile dysfunction intensity (EDI) assessed after the cardiac rehabilitation program in the study group was 14.35 ± 6.88 (95% CI = 13.08-15.62), and it was statistically significantly greater from initial EDI. Mean final training work was statistically significantly greater than mean initial training work. From among the parameters describing training work, none were related significantly to reduction of EDI. In conclusion, cardiac rehabilitation program–induced improvement in erection severity is not correlated with endurance training intensity. Chronotropic response during exercise may be used for initial assessment of change in cardiac rehabilitation program–induced erection severity.

Full textAbstract:
Since ancient times, wooden structures have been used by man for the construction of buildings and facilities. For many centuries, the structural elements of buildings and facilities made of wood have been the main ones, and still have broad prospects for use in modern capital construction, as they have sufficient high strength and stiffness, are reliable and durable, while having a small mounting weight. In particular, a number of Western countries are already erecting high-rise buildings using a framework of laminated wood constructions. The indisputable advantage of wooden structures is environmental friendliness. However, with all the harmony of the wood structure, its tracheid’s are not standard, which is the main reason for the variability of its mechanical properties. With alteration of a cross-section of flexural member, the nature of the load distribution, as well as the nature of the fracture, changes. An additional factor that affecting the force distribution is the nature of the reinforcement and methods of the reinforcement fixing methods. The methods used to calculate the “low” reinforced beams often give a large error in the calculation of “high” beams. In the work, a rational methodology for calculating wooden glued reinforced beams with symmetrical reinforcement is determined.

Full textAbstract:
Enron shows us dramaturgy gone amuck. In this article, critical theory and postmodern theory are crossed to form a critical dramaturgyresulting in two main contributions. First, critical dramaturgy is differentiated from other forms of dramaturgy, showing how ‘spectacle’ is accomplished through a theatrical performance that legitimates and rationalizes, and casts the public in the role of passive spectators. Second, critical dramaturgy has important connections with public relations theory. While contemporary public relations is concerned with the building of relationships, critical dramaturgy looks at how corporate theatrical image management inhibits relationships by erecting the barrier of the metaphorical proscenium. The Enron scandal is viewed as the collapse of a corporate spectacle illusion into megaspectacle fragments. These fragments include the naming of Enron, the Valhalla Rogue Traders scandal, the Gas Bank, Greenmail, Cowboy Capitalism, the Skilling–Mark rivalry, and the Masters of the Universe theme. Intertextual analysis demonstrates how these fragments contribute to the ‘Greek Mega-tragedy’ of the Enron megaspectacle. The article integrates several corporate theatre processes relevant to understanding four types of spectacle: concentrated, diffused, integrated, and megaspectacle. The value of the critical dramaturgy conceptual work is to lift the romantic veil of spectacle theatrics to reveal the antenarrative fragments of stories marginalized and backgrounded.

During the course of work in Cyrenaica extending over the 1950s and 1960s I was asked by the late Richard Goodchild, then Controller of Antiquities, to note and comment on any architectural features which I felt to have special significance. In this way, across the years, I handed over to him various short notes with drawings of miscellaneous items that I had observed. Of one such observation a copy has come to hand recently among old papers.While working with the Michigan Expedition to Apollonia (1965–68) I visited the late Professor Stucchi's project for re-erecting the remains of the Temple of Zeus at Cyrene, begun in 1967. During the visit I was interested to observe the detailing of a triglyph block from the peristyle entablature. This seemed to conflict with, or rather to add somewhat to the then accepted building history of the temple — i.e. a (late) Archaic Greek Temple overthrown during the Jewish Revolt and subsequently refurbished minus the peristyle.Work on Professor Stucchi's project is not yet completed; and although he published both progress reports and some discussion of the findings, he has not, to my knowledge, given us a detailed account of the evidence for the history of the building; so perhaps my note made in 1968 remains of interest. I have left the argument as it stood, but some updating material has been added to the footnotes.G.R.H.W.Avignon, December 1993.

This paper is an attempt to discuss some economic aspects of metrology, the field of study dealing with measurements. The first part of the paper deals with what might be called the economics of precision; the second discusses the public goods nature of a system of measurement, and the third economic aspect of metrology concerns occupational entry barriers. Even though a market demand and supply in the usual sense do not exist, a system of weights and measures does have many traditional economic characteristics. For example, the measures themselves came about in response to emerging needs to measure with varying degrees of accuracy the commodities that were traded in society. Just as technology has affected the supply of traded goods, so too has it affected the supply of tools of measurement and their precision. The first two sections of the paper will describe our system of weights and measures as an evolutionary process much like how traditional commodity markets work. Individuals and governments have promoted the standardization of units and their accuracy when it served to facilitate a more efficient allocation of resources. The public goods nature of a standardized system of weights and measures will be discussed with emphasis on government involvement. The third section of the paper will discuss some instances in which our system of weights and measures fails to promote economic efficiency. Specifically, we will discuss the rent-seeking behavior by some to implement nonstandard measures as a means of erecting occupational entry barriers.

The solar chimney and power tower are two of modern promised energy which can develop bylow losses, simplicity and high power.In this paper, the solar chimney and fossil fuel power tower parameters are studied by usingtheoretical equations in computational fluid dynamics CFD that substituted in some computerprograms such as MATLAP and FLUENT codes with additional related expressions. Fivedifferent models are used in this paper (Chimney height is: 12, 15, 20, 25, and 35 meter),(Diameter of collector base is: 5, 8, 10, 15, and 20 meter). The effect of inlet collector height,collector absorbability, solar radiation, ambient temperature, solar collector thickness and solarcollector tilt angle are studied to find the other parameters and properties such as velocitydistribution, power and efficiency of system. The erecting of power turbine is predicted byfindings the velocity distribution between the base and chimney assembly. The numericalanalysis was presented by using GAMBIT and FLUENT 6.3 to predict that high velocity at theexpansion of chimney near the center of base – chimney bond position because of low density ofair as a result to solar radiation flux (and burned gases cover collector in case of using thechimney for combustion of gases in oil refineries).. This position is very suitable for promotingand building the power turbine. The maximum power accumulated from these techniques is morethan (6.7×105 Watt) where the velocity is (17.5 m/s). The study concluded that it is easy work toerect these chimney and power tower techniques closed to drilling and oil facilities in remoteareas. So, all factors were studied to coincide with previous papers in this field.

Full textAbstract:
The most famous and relevant innovative type of construction reorganization of urban areas is renovation that is defined in the directive documents of the Moscow Government as the demolition and dismantling of buildings in conditionally autonomous urban areas, defined by the well-known Resolution of the Moscow Government and legal documents explaining it, without taking into account the degree of physical or moral aging of these buildings and structures with the aim of erecting multi-storey residential buildings with increased comfort living in these territories. Thus, a certain meaning of renovation makes it possible and necessary to purposefully study and model the life cycle of this socio-technical and organizational-technological construction process, which has certain formal differences from the well-known model of the traditional life cycle of a construction facility and the sequence of stages in the implementation of this life cycle. The difference in the configuration of the life cycle of a construction facility in the traditional approach and in the innovative one in the conditions of renovation has been determined. In the study, this difference highlights the stage of demolition and dismantling, with which the problem of disposal of construction waste is inextricably linked. In this regard, an urgent task of comparing options and optimization of sorting and collection of waste at demolition and dismantling facilities at the first stage of renovationarises. Three options for solving this problem and projects for the production of work have been developed for each of the three options for the demolition and dismantling of buildings. The most rational is the second option.

75% of men with coronary artery disease confirmed by coronarography have erectile dysfunction in history, while 75% of patients with a vascular etiology of ED have significant stenoses in penile arterial vascularization. Patients with coronary artery disease have shown a relationship between the range of the lesions in the coronary vessels and erectile dysfunction intensity. This paper aims at attempting to systematize the knowledge of the benefits and drawbacks of nonsurgical endovascular treatment methods for erectile dysfunction with confirmed vascular causes. It analyzes seven studies which assess the results of erectile dysfunction treatment with percutaneous angioplasty. It also mentions the limitations of the cited works and formulates relevant conclusions. Conclusions: The analysis shows that endovascular procedures in erection-related arteries are safe in a specially selected group of men. It is necessary to conduct further studies to define an appropriate group of patients who have a chance of benefiting optimally from the endovascular treatment of erectile dysfunction in a long-term follow-up.

We apply elementary canonical methods for the quantization of 2+1 dimensional gravity, where the dynamics is given by E. Witten’s ISO(2, 1) Chern-Simons action. As in a previous work, our approach does not involve choice of gauge or clever manipulations of functional integrals. Instead, we just require the Gauss law constraint for gravity to be first class and also to be everywhere differentiable. When the spatial slice is a disc, the gravitational fields can either be unconstrained or constrained at the boundary of the disc. The unconstrained fields correspond to edge currents which carry a representation of the ISO(2, 1) Kac-Moody algebra. Unitary representations for such an algebra have been found using the method of induced representations. In the case of constrained fields, we can classify all possible boundary conditions. For several different boundary conditions, the field content of the theory reduces precisely to that of 1+1 dimensional gravity theories. We extend the above formalism to include sources. The sources take into account self-interactions. This is done by punching holes in the disc, and erecting an ISO(2, 1) Kac–Moody algebra on the boundary of each hole. If the hole is originally sourceless, a source can be created via the action of a vertex operator V. We give an explicit expression for V. We shall show that when acting on the vacuum state, it creates particles with a discrete mass spectrum. The lowest mass particle induces a cylindrical space-time geometry, while higher mass particles give an n fold covering of the cylinder. The vertex operator therefore creates cylindrical space-time geometries from the vacuum.

This note summarizes and expands one of the short papers communicated to the Society on 23rd February 1995 under the title of ‘New Thoughts on Some Castles in Wales’.The paper's purpose was twofold. First, it sought to present, through a series of ‘before and after’ photographs (figs. 1-8), an up-to-date picture of the transformation effected at Conwy in the course of the last forty years, not only by the careful and conservative repair of the fabric of both components of the monument, i.e. town walls as well as castle, but also by the systematic clearance wherever possible of every kind of built disfigurement from the forefront of the medieval enceinte, so as to reveal and display anew the whole circuit of towers and curtains in an ambience worthy of Britain's most outstanding example of medieval town fortification. Closely related to the process of gradually re-establishing awareness of the monument's unity, with the walls receiving the same respect, in financial as in other terms, as the castle and the work of repair proceeding simultaneously on both, was the defeat, likewise a long and complex process, of the Welsh Office's proposal effectively to destroy the natural setting and amenity of the whole southward aspect of castle and walls alike by driving a dual-carriageway ‘express-way’ through the Gyffin valley (brazenly promoted as the Minister's ‘preferred route’) and erecting a monster new suspension bridge whose ‘goalposts’ would have overtopped even the turrets of the castle towers. The abandonment of this disastrous plan, in favour of the submerged tube tunnel under the river opened by H.M. the Queen in October 1991, was of incalculable benefit in preserving Conwy's unique character into the future. As such, it has its proper place in the present record (figs. 9-12).

Full textAbstract:
Erectile dysfunction (ED) is a common sexual problem and has been attracting growing interest from the field of medicine. The pharmaceutical industry works together with medical associations to popularize the theme, emphasizing individual enhancement and medication, besides reinforcing an idea of a male sexuality defined by the ability to have an erection and penetrate. Patients worried about erection problems search for general practitioners (GPs), frequently without a clear complaint, and a comprehensive primary health care (PHC) must be capable of dealing with these issues considering medicalization and disease mongering. This article discusses how PHC physicians take (and might take) care of men with erection problems, and how users perceive it and search for help in two cities in the State of São Paulo, Brazil. The qualitative research, performed in five PHC services, included semistructured interviews with 16 GPs and 15 adult male users. The adult male users were invited by their doctors during consultations where questions about prostate, ED, or other sexual problems arose. Interviews were transcribed and submitted for content analysis. In addition, the five participating services were observed with help of a specific script. Results indicate that ED is frequently a hidden agenda and that doctors have trouble approaching the problem, usually focusing on the biological aspects. Based on empirical data and literature, this work indicates some measures to qualify the care of men with ED in PHC which includes contemplating users’ questions, respecting their autonomy, avoiding an antidrug stance, and considering drug and nondrug approaches as a continuum of resources.

Functional imaging with positron emission tomography and single photon emission computed tomography is capable of visualizing subtle changes in physiological function in vivo. Erectile dysfunction(ED) diminishes quality of life for affected men and their partners. Identification of neural substrates may provide information regarding the pathophysiology of types of sexual dysfunction originating in the brain. The aim of this work is to verify the approaches of the nuclear medicine techniques in the evaluation of the erectile function/disfunction. A search using the words ED and nuclear medicine, ED and scintigraphy, ED and spect and ED and pet was done in the PubMed. The number of citations in each subject was determined. Neuroimaging techniques offer insight into brain regions involved in sexual arousal and inhibition. To tackle problems such as hyposexual disorders or ED caused by brain disorders, it is crucial to understand how the human brain controls sexual arousal and penile erection.

Full textAbstract:
Purpose – This paper is one of the first attempts to explain the local dynamics of the 2010 ethnic riots in Kyrgyzstan. No scholarly work has attempted to systematically analyze the 2010 ethnic violence and its local dynamics on the neighborhood scale. The purpose of this paper is to shed light on this gap by analyzing neighborhoods’ responses to the emerging violence in the city of Osh. In order to do this, the author compares two typical neighborhoods in Osh, one violent and the other non-violent, with different spatial structures and built environments that demonstrate/represent similar dynamics of riots in many other neighborhoods. Design/methodology/approach – The empirical findings of this paper are based on the ethnographic fieldwork the author carried out in 2010 and between 2012 and 2014. During nine months (in total) of the author’s ethnographic fieldwork, the author conducted around 60 semi-structured interviews in Osh city mainly with community leaders. In the author’s interview sampling, the author used two approaches: the snowball method and geographically/territorially representative sampling. Findings – The author argues that among other factors, a particular type of public space provides favorable conditions for riot occurrence or non-occurrence. For example, in Osh, such places as areas around the central bazaar and densely populated multi-story building complexes were especially riot-prone. By contrast, residential areas with individual-unit houses and low residential mobility represented communally private spaces with more easy riot-control. In addition, some residential areas implemented strategies such as physical self-isolation to avoid violence. By restricting freedom of movement and erecting improvised barricades, the residents of such neighborhoods created a temporally new space with its own rules and interethnic cooperation. Originality/value – This paper suggests new insights in the analysis of riots by connecting theoretical categories and concepts of space provided by scholars of contentious politics and applying them to the case of the 2010 ethnic riots in Osh city. By analyzing riot dynamics on the neighborhood scale, this research contributes to the understanding of the spatial dynamics of ethnic riots.

Full textAbstract:
An important task in the construction of buildings and structures is the choice of the most rational solutions in terms of organization and technology of construction production. Currently, the complexity and variety of organizational and technological decisions in the dynamics of the process of erecting buildings and structures for various purposes requires research. To this end, it is necessary to improve existing or develop new organizational and technological solutions, in conditions when the tasks are set to increase the growth in the volume of housing construction. The author is faced with the task of forming an integrated system that includes organizational and technological solutions, methods and assessment of the effectiveness of the study. It is assumed that the results of the study will be in demand by construction organizations to maintain competitiveness, paying attention to organizational and technological solutions, both at the stage of preparation and during construction. This will prevent losses, increase the effective functioning of construction organizations in the market, and strengthen their business reputation. Scientific novelty lies in the formation of parameters and their classification, methods of modeling organizational and technological solutions. To assess organizational and technological solutions, it is necessary to study methods and ways of measuring them. In the course of the research, an analysis of the methods widely used at present for the qualitative and quantitative assessment of organizational and technological solutions was carried out. Qualitative assessment methods make it possible to reveal the significance of certain factors of a phenomenon through the analysis of competent opinions. In the case of studying the influence of organizational and technological solutions on construction processes, there are no measurable physical parameters, objects inaccessible to perception and large volumes of statistical data. The article concludes that empirical, theoretical and quantitative methods are difficult for the research chosen by the author. Therefore, the author of this article chose the Monte Carlo method (MCM) as a research method - a group of numerical methods for studying random processes. Also, the work identified a vector for further research.

Full textAbstract:
When erecting monolithic reinforced concrete structures, the structure of concrete can differ significantly from the laboratory standard due to the complexity of providing favorable conditions for hardening, and therefore the compressive strength and especially the frost resistance of concrete may not meet the design requirements, which can negatively affect the reinforced concrete structure durability and require amplification, especially in earthquake-prone areas [1, 2]. Increasing the durability of reinforced concrete structures is possible by creating a rational stress field, for example, by prestressing, incl. variable along the length of the structure [3,4], but this technique is difficult to implement for monolithic reinforced concrete structures. It is possible to use effective materials or methods of manufacturing structures [5, 6]. But this is also mainly problematic for use in the construction of monolithic reinforced concrete structures. Generally accepted methods of calculating the reinforced concrete structures durability subjected to cyclic freezing-thawing during operation, incl. in a water-saturated state, do not exist. At the design stage, ensuring the durability of such reinforced concrete structures is mainly reduced to the reasonable assignment of requirements for concrete quality indicators, depending on the operating conditions, which is the focus of BC 28.13330.2017 (EN 206) and GOST 31384-2017 from the premise of ensuring durability of at least 50 years. In the above-mentioned norms of the Russian Federation, in fact, two approaches are presented to ensure the durability of reinforced concrete structures during cyclic freezing-thawing, incl. in a water-saturated state, namely: designing a concrete structure capable of working under such conditions by standardizing the values of cement consumption, W/C ratio, class of concrete in terms of compressive strength, amount of entrained air, or rationing of concrete grades in terms of frost resistance F1 (first base method GOST 10060-2012 provides for freezing in air, saturation and thawing in water) or F2 (second base method GOST 10060-2012 provides for freezing in air, saturation and thawing in 5% sodium chloride solution). The purpose of this work is to compare various approaches to ensuring the durability of reinforced concrete structures operated during cyclic freezing-thawing and to analyze the provision of durability with standardized indicators when designing the structure of concrete.

Full textAbstract:
In recent years, the requirements for the level of the life quality have increased significantly; an integral part of it is the sexual harmony, which in men largely depends on sexual desire and erectile function. According to the results of modern scientific studies, there is no doubt that erectile dysfunction in men is closely connected with the cardiovascular diseases, obesity, diabetes mellitus and other comorbidities. This problem can also be caused by systematic psycho-emotional overload, deterioration of the environmental conditions, harmful factors of production, uncontrolled use of medicines, inflammatory processes in the genital organs, the growth of somatic diseases. The vast majority of works concerning “male menopause” is reduced to the effectiveness of hormone-replacement therapy in erectile dysfunction, while only few research works are devoted to the study of the connection between somatic pathology and androgen deficiency. There is a negative correlation between total testosterone level and systolic blood pressure. According to the research results of some scientists, it was found that 38% of patients with arterial hypertension had androgen deficiency, confirmed in the laboratory, which is significantly higher than in patients of the same age category with normal blood pressure. These dominant factors exert and increase the influence on each other, which must be taken into account in modern therapeutic practice. The study of the formation of comorbid conditions in men with low levels of androgens is of particular importance, as the knowledge of pathophysiological mechanisms can prevent their development and progression. The aim of this investigation was to study the state of penile vascular blood flow in men with arterial hypertension with erectile dysfunction, using color Doppler imaging with pharmacological induction of erection. The indicators of daily monitoring of arterial pressure and arterial stiffness in men with arterial hypertension of the II degree against the background of androgen deficiency or at normal testosterone levels and ways of correction of erectile dysfunction in these patients were also evaluated.

Full textAbstract:
AbstractPriapism is characterized by persistent penile erection in the absence of sexual arousal or desire that does not subside with orgasm. Although relatively uncommon, it is a genitourinary emergency that necessities prompt work-up and appropriate management, as there is a time-dependent relationship between total duration of erection and an increasing risk of permanent erectile dysfunction. Confirming the type of priapism is key to proper management, but the majority of cases presenting to the emergency department are ischemic in nature. Conservative management strategies for ischemic priapism are sparsely described in the literature but generally include ice pack application to the area, cold showers, masturbation and rarely, exercise. These strategies lack sound evidence, but the risks of attempting them are minimal as long as access to more definitive treatment is not delayed. Lower-limb exercise as a first-line treatment warrants further study in the undifferentiated emergency department priapism population. The case we present and discuss here illustrates the potential benefits of a trial of acute lower-limb exercise, specifically stair climbing, as a treatment for medication-induced priapism. If effective, this simple non-invasive management strategy may decrease the time to effective treatment, requires minimal resource utilization, and ultimately, avoids the need for more invasive treatment.

Full textAbstract:
Thirty million men in the U.S. suffer from erectile dysfunction (ED) defined by their inability to achieve or maintain a penile erection sufficient for intercourse. An unestimated number of women also suffer from sexual dysfunction resulting from many of the same causes that lead to ED in men. There are a variety of treatments available for ED including intracavernosal injection, transurethral therapy, surgery, vacuum therapy, and oral medication. Unfortunately, not all patients benefit from these currently available forms of therapy, and side effects are not uncommon. Sildenafil (Viagra) has been a highly successful drug for the treatment of ED but it does not work in all men [5]. Some may experience a variety of side effects, and Viagra is contraindicated to some cardiac medications. These problems point to the need for new and different approaches to the treatment of sexual problems.

Full textAbstract:
Purpose This paper aims to present experimental work examining the effect of opening size on the collection efficiency of cavity-type receiver geometries, e.g. modified cavity and spherical cavity with single- as well as dual-stage water heating. The correlations, obtained using the experimentally obtained data, are helpful in designing of cavity receivers (modified and spherical geometry type) to be used in solar-power harnessing assignments/projects, for yielding better system performance. Design/methodology/approach The parameters of study encompass receiver opening or aperture ratios (d/D, ratio of diameter of opening to the maximum diameter of spherical cavity) of 0.4, 0.47, 0.533 and 0.6; flow Reynolds numbers of 938, 1,175, 1,525 and 1,880 with water as a coolant; and receiver inclination angles of 90, 60, 45 and 30° (with 90° as receiver-opening facing downward and 30° as receiver-aperture facing closer to sideway). A modified cavity receiver was examined for opening ratios of 0.46, 0.6, 0.7 and 0.93. The glass covers, with thickness 2, 4 and 6 mm, were positioned at the opening of cavity to mitigate the energy losses. Findings The experiments have been conducted at a lesser incoming radiative heat flux, for receiver cavity wall surface temperatures ranging from 90°C to 180°C. The collection efficiency values of both the receivers, modified cavity and spherical cavity types, are seen increasing with coolant flow rate and receiver tilt (inclination) angles, i.e. 30° → 90°. The collection efficiency exhibits maxima at an opening ratio of 0.533 in case of both single- and double-stage spherical cavity receiver. This value was observed as 0.6 for modified cavity receiver. The mathematical correlations developed for obtaining the collection efficiency values of modified cavity-type receiver, spherical cavity receiver with single stage and spherical cavity receiver with dual-stage water heating are given as ɳ=0.4667 Re0.0798dD0.1651 δ0.0281θ̇−0.011, ɳ=0.2317 Re0.124 dD1.265δ0.0192θ̇0.2914 and ɳ=0.1137 Re0.1715dD0.8702θ̇0.2757, respectively. Social implications The findings of the paper may be helpful in erecting concentrating solar collector systems for household water heating, concentrating solar-based power generation as well as for various agricultural applications.

Introduction: Plaque incision and grafting represent the best surgical approach to the Peyronie’s Disease (PD). The grafting procedures must be restricted to patients with normal preoperative status, excessive curvature and/or deformities. However, the ideal graft has not been identified yet. Buccal mucosa grafts (BMG) provided excellent short-term results, ensuring the fast return of spontaneous erections and preventing shrinkage, which is the main cause of graft failure. Another fearsome surgical complication is de novo erectile dysfunction (ED). We report our results with BMG focusing on the analysis of ultrasonographic and clinical data demonstrating buccal mucosa as determinant factor that allow to avoid complications. Materials and methods: From 2013 to 2019 we performed at our Urology Unit 27 corporoplasties with BMG to correct complex penile curvature due to PD. Clinical, post-surgical and ultrasound follow up data were evaluated. All patients were no responders to medical treatment or previous surgical procedures. The evaluation period was 72 months. Data regarding pre-operative work-up, including IIEF (IIEF-5) questionnaire administration, detailed clinical history and penile dynamic ultrasound (PGE1-induced erection) were collected. The time of spontaneous erection resumption was recorded for each patient. To improve blood supply to the graft, a low-dose PDE5-i was prescribed for all patients for a period of two months, starting immediately after discharge. Check-ups were scheduled every 3 months, starting from 1 month after surgery. In each visit, patients underwent a penile ultrasound evaluation of graft features. After 6 and 12 months, all patients underwent a penile dynamic ultrasound for Erection Hardness Score determination, then standard ultrasound and clinical evaluation yearly. Our analyses were focused on BMG as a major determinant of the surgical success. Results: Mean age of 27 patients was 57 years (42-71) with a maximum follow up time of 72 months and minimum of 3. Site of penile curvature was dorsal in 18 (67%) patients, ventral in 2 (7%), complex in 7 (26%). The degree of the curvature was < 60° in 11 (41%) patients, > 60° in 16 (59%). Straightening of penis was reached in 100% of cases. Penile shortening resulted in 7.4% (2/27). De novo ED appeared in 2/27 cases with a post-operative rate of PDE5i users increasing from 12 to 14 patients (45% vs 52%). Ultrasound aspects of BMG, recorded at every follow up visit, results in a hypoechoic plaque with an iperechoic rim that become isoechoic over the time in all cases. No case of scars or seroma was registered. Small intra-graft cystic lesions were highlighted in 3 cases (11%).Conclusions: BMG may represent a good choice in grafts procedures for PD surgical management. The functional results obtained by BMG procedures were related to the good anatomical characteristics of the patch and were highlighted in our series by use of penile ultrasound, during the follow up period.

Full textAbstract:
Research on penile smooth muscle physiology has increased the number of drugs available for treating erectile dysfunction (ED). Penile erection involves the relaxation of smooth muscle in the corpus cavernosum. The key mediator of smooth muscle relaxation is nitric oxide (NO), which acts by increasing the cellular level of cGMP. Another cyclic nucleotide, cAMP, is involved in smooth muscle cell relaxation; cAMP formation is stimulated by a number of compounds, such as alprostadil. An increase in cAMP and/or cGMP levels can also be induced by inhibition of phosphodiesterases (PDEs), the enzymes involved in cyclic nucleotide breakdown. Both papaverine and sildenafil are PDE inhibitors. Papaverine is a non-specific inhibitor of these enzymes; sildenafil is an orally active, potent and selective inhibitor of GMP-specific PDE5, the predominant isoenzyme metabolizing cGMP in the cells of the corpus cavernosum. Penile smooth muscle contraction, induced by adrenergic fibers through alpha(1) adrenoceptors, produces detumescence, thus making alpha adrenoceptor antagonists suitable for maintenance of penile erection. The orally active drug yohimbine is a mixed alpha(1)-alpha(2) adrenoceptor antagonist that works by a dual mechanism; it facilitates sexual arousal by acting on alpha(2) adrenoceptors in the central nervous system and blocks adrenergic influences at peripheral level.

Full textAbstract:
Radical prostatectomy remains the gold-standard treatment for localised prostate cancer. Despite the widespread introduction of nerve-sparing techniques, post-operative erectile dysfunction (ED) is still a significant source of morbidity. There are multiple approaches to prevent and treat ED. Recent refinements to surgical technique attempt to minimise disruption to the prostatic neural and arterial supply. A greater understanding of the factors affecting ED has also enabled the first multi-variate risk stratification model, thereby potentially improving awareness of pre-operative risk. Numerous on-demand treatments are available, including phosphodiesterase type 5 inhibitors, intracavernous/transurethral alprostadil, vacuum erection devices and combination therapy with multiple agents. As our understanding of the aetiology improves, attempts to manipulate the molecular mechanisms underpinning ED are also being investigated. In addition, early pharmacological rehabilitation is used to preserve cavernosal smooth muscle function until intra-operative neurapraxia resolves, although the optimum regimen is yet to be defined. Currently, much work is ongoing to improve our understanding and treatment of post-prostatectomy ED. We review the current status and recent advances in this field.

Impairment of social functioning and low economic status may lead to the development of cardiovascular disease (CVD). This study aimed to evaluate the relationship between socioeconomic status (SES) and erectile dysfunction (ED) in patients with clinically significant CVD. A total of 808 male patients with ischemic heart disease (IHD) were recruited. Socioeconomic and demographic data as well as occupational data and the presence of modifiable risk factors were collected. Erection quality was assessed using the International Index of Erectile Function 5 (IIEF-5), while physical activity was evaluated using a modified Framingham questionnaire. Relationships among the presence of socioeconomic factors (marital status, education, income, occupational status, nature of work conducted, and demographic data), intensity of ED, and time from diagnosis of IHD were assessed. ED was diagnosed in 618 men (76.49% overall; severe in 23.14%, moderate to severe in 13.11%, moderate in 32.20%, mild in 31.55%). Patients with ED were older (61 ± 8.6 vs. 53 ± 9.1 years; p < .0001), were less active (6.97 ± 2.18 vs. 8.31 ± 2.34 Metabolic Equivalent [METs]; p < .0001), and had more modifiable risk factors (3.4 ± 1.1 vs. 3.2 ± 1.0; p < .0300). Higher education was associated with a lower probability of the occurrence of ED (OR = 0.7546; 95% CI [0.6221, 0.9153]). In patients with newly diagnosed IHD, SES correlated significantly with the presence of ED ( p = .009). Education in patients suffering from CVD has a significant relationship with both the occurrence and degree of ED. Economic status was significantly linked to the presence and degree of ED only in patients with IHD diagnosed less than 2 months before entering the study.

Full textAbstract:
High-rise building structures in the course of its erection suppose primary use of methods provided for erection, concrete and external finishing works. Erection works do not differ significantly from usual ones: traditional equipment, accessories and techniques are used which are based on erection of structures in project position using a crane. Structures to be assembled in building frame include steel columns and beams, wall panels, form elements of columns, walls and floor structures. We can note heightened attention to operational control for quality of erection, but it is attributable to all works in the course of high-rise construction. During high-rise erection by means of cast in-situ reinforced concrete all formworks to be used do not have any special differences except systems specially designed for high-rise erection using sliding formwork or vertical traveling forms. In these systems special attention is paid to safety of elevated works. Working methods of placement and curing of concrete and structures as a whole remain traditional – the requirements for controlling such operations become toughened. The most evident differences in high-rise erection with regard to equipment, machinery and accessories used are in means provided for load transportation and safety of works at heights. Particularity of internal finishing works which are also obligatory during construction of skyscrapers allows not considering them in as technological differences from usual construction as far as the «height» of its execution is limited by height of particular floor and determined by price and building class.

The construction of territories with problematic engineering and geological conditions in the presence of unstable, crossed relief is a complex geotechnical task. Therefore, the main purpose of the work is to study the features of the ground anchor, which is made by electric discharge technology, as a monolithic reinforced concrete structure. The questions related to the provision of safe methods of construction and erection works for the erection of any facility in such territories are related to a multifactor problem connected, primarily with the need to develop special geotechnical technologies tied to real engineering and geological conditions, loads from previously erected buildings and structures and, secondly, the actual implementation of them on a particular construction site. The case considered in the article from the geotechnical practice of construction of the facility is confirmed by the fact that due to the availability of modern design and construction and construction works, it is possible to solve any complex problems related to the issues of ensuring the stability of slopes.
