Hence economic growth requires more and more investments in the harbor area, especially nearby waterfront structures, a special attention must be taken into account regarding proper infrastructure design for structures with high vertical loads. At the same time, we have to consider the good behavior of the new design structures and also their impact on the existing nearby waterfront infrastructure. Being adjacent to waterfront structures and due to the limited available space, these structures are typically tall and narrow, and exert average soil pressures on the order of 300KPa. These loads can only be accommodated by ground with an adequate bearing capacity. This publication presents case studies of waterfront projects like grain silos storage facility. Available results for the certification and monitoring of the works are also presented, as well as other considerations based on the author’s experience.
The calculation of the friction factor involved in the Darcy-Weisbach equation has a key role in the accurate assessment of distributed head losses. For the turbulent flow regime, this friction factor was mathematically expressed in the form of the Colebrook-White (C-W) equation, widely accepted by engineers and scientists. Nevertheless, the C-W equation is an implicit one and must be solved using numerical methods. This is a major disadvantage for the average engineer, who always prefers an explicit equation which could be easily integrated into his familiar spreadsheet environment. The present paper is investigating some of the most used explicit alternatives to the C-W equation, with respect to several case scenarios taken from typical Building Services hydraulic calculations.
The paper focuses attention on the problem of increased risks during the loading and unloading of railway tankers. To evaluate the risk which may occur during loading dangerous goods into tanker trains, the loading processes have been divided into seven stages. Based on HIRA risk analysis, for each stage of improvements, Quick Kaizen tasks were proposed. Special attention was paid to possible improvements in technical means, tools and processes. Thanks to the proposed improvements, it is possible to increase safety, not only during the loading of dangerous goods, but also in cases of loading and transportation of standard cargoes.
This article is aimed at providing a rationale for the need to introduce a new type of educational institution in Ukraine today, namely educational centers in the areas with challenging topography. This article identifies specific features of construction, given the difficult geographic topography and architectural environment of the educational institutions, and lists conditions impacting the volume and planning of educational facility construction. It defines how urban planning of school centers influence the areas with difficult topography and establishes their location type. The authors analyzed architectural and construction solutions for school centers in areas with challenging landscape. They have also identified form-shaping types of buildings and established the best slope ratio for each of the types.
The use of composite systems in protecting, preserving and maintaining historical monuments has become more and more used. There are several consolidation procedures with fiber-reinforced polymeric polymers that can be applied as required or on the basis of the basic material (concrete, masonry, wood, etc.). Besides the many advantages it provides, the application of composite systems in the rehabilitation of heritage buildings and historical monuments requires minimal workmanship. More and more cities are actively involved in the rehabilitation and preservation of heritage buildings and historical monuments by launching good practice guides to preserve local cultural heritage by applying composite elements as robust as possible without the need to modify the overall dimensions of the buildings through a classic covering.
After the proclamation of the Republic of Latvia in 1918, Latvia experienced a rapid influx of youth into its capital city of Riga, looking to obtain education in universities. Students began to build their academic lives and student societies. In 1923, students of the Art Academy of Latvia founded the “Dzintarzeme” (“Amberland”) fraternity. The aim of “Dzintarzeme” was to unite nationally minded students of the Art Academy of Latvia and to promote the development of national art and self-education. Most “Dzintarzeme” members were faithful to the old masters and Latvian art. This phenomenon is significant, because “Dzintarzeme” members grew up with Latvian painting traditions, which are a remarkable heritage of interwar Latvia.
In 1940, when Latvia was occupied by the Soviet Union, “Dzintarzeme” was banned. A part of “Dzintarzeme” members were deported, killed in war, went missing, or stayed in the Latvian SSR; the remaining chose exile. Although scattered throughout the United States of America, Canada, and Australia, some members were able to rebuild and sustain the fraternity’s life, gathering its members, organising trips and anniversary art exhibitions.
The aim of this research is to reflect on “Dzintarzeme’s” activities in exile (1958–1987), focusing on the main factors of Latvian national art conservation policy: first, the ability of “Dzintarzeme’s” ideology to preserve the values of Latvian national art in an international environment, and second, the problem of generational change and the enrollment of young Latvian artists who continued to maintain “Dzintarzeme” values in exile.
This paper presents a part of a comprehensive study on non-compliant landfill in Vaslui County. We have been tracking the subsidences taking place in the body of waste dumps and the amount of gas removed to take the best post-closure monitoring measures. In order to trace the behavior regarding the subsidence in the landfill body, there were placed in the ground 11 milestones/topographic landmarks of plastics, painted in white and red to be easily identified visually. Keeping them on the same positions made possible the analysis in the present study. Topographic surveys in the ground were performed once a month between April 2014 and September 2015. The results, interpretations and proposed solutions are presented in this paper.
New trends in sustainable design contribute to prevention of the deterioration of the natural environment and they are focused on the optimisation of the indoor environment for the improvement of the human life quality. There are complementary goals of sustainable design – the comfort of architecture users, proper spatial planning, and, as a priority, taking into account the needs of both contemporary and future generations. These existential needs are connected with both local and global sozological problems. These are related to the continuing growth of irreversible changes to the environment, such as climate change, the disappearance of biodiversity, and the over-exploitation of nonrenewable sources of energy as result of shortsighted economy. These imply the necessity for the sozological education in all subjects of study and transdisciplinary training focused on the solving of problems associated with sustainable development.
This article is dedicated to the “Baltars” collective porcelain painting workshop (1924–1930), founded in Riga, Latvia by three modernist artists: painters Romans Suta (1896–1944) and Aleksandra Beļcova (1892–1981) and graphic artist Sigismunds Vidbergs (1890–1970).The “Baltars” phenomenon is significant because of the innovations that the artists brought to the landscape of Latvian porcelain manufacturing and its exhibition activities in the 1920s and the early 1930s, both local and in the Baltic Sea region—Lithuania, Estonia, and Sweden. The article investigates “Baltars” foundation and closure, artistic activities of the company, its attempts to enter the international art and trade scene, and its accomplishments. Special attention is paid to the amalgamation of modernisation, nationalism, and state-building manifested in their paintings on porcelain. Due to the present growing interest in porcelain art in Latvia, triggered by numerous exhibitions and publications, discourse on the “Baltars” phenomenon has become topical.
The present paper shows the advantages in using this prototype of tension and compression test machine proposed by the authors. The mechanical behaviour of different materials and components can be easily obtained by using this type of device. The equipment enables a simplified change between the types of testing performed. The operators can quickly and easily change elements and accessories used in testing. This equipment is the suitable choice for evaluating different types of friction dampers.
