DYNAMICS, STRUCTURE AND DRIVERS OF FISH CATCH IN RUSSIAN FEDERATION (2005–2017)
Authors: Samoylenko V. V.
Published: July 2019

The main trends in fisheries are considered by the fishery basins, including dynamics of annual catches and changes in their structure, both for inland and marine areas, on the data of fishery statistics for 2005–2017. The landing in the inland waters of Russian Federation is estimated as 8.4–10.0 % of the total national annual catch. Its mean annual volume for this period was 375.103 t; it grew on average in 2.2 % annually. This volume was landed mainly (85 %) in four inland basins: Volga-Caspian, Far Eastern, Azov-Black Sea, and West Siberian ones. About ⅓ of the volume was provided by cultivated fish, in particular in the Azov-Black Sea basin (87 % of the total freshwater catch) and Northern basin (69 %). Marine fishery produced 2990–4644 . 103 t, or 90.0–91.6 % of the total Russian catch. Its annual landing has increased by more than a half since 2005, with the average growth in 3.7 % annually. This volume was landed mainly within the exclusive economic zone (EEZ) of Russia — 74.7 %, the rest was landed in the neutral areas of the World Ocean (5.9 %) or in EEZ of foreign states (19.4 %). The main region of marine fishery is the Far-Eastern basin, which portion in the national catch increased in 13 years from 62.6 % to 68.7 %, whereas the portion of the Northern and Western basins decreased in 3.7 % (to 21.5 %) and 3.0 % (to 7.9 %), respectively. In the Far-Eastern basin almost whole catch was landed within EEZ of Russia (3149 . 103 t), though in the Northern and Western basins the catch was obtained mainly in EEZ of foreign states (on average 557 . 103 t and . 103 t, respectively) and beyond EEZ (116 . 103 t and 94 . 103 t, respectively). Influence of the export supplies on the fish supply to the domestic market of Russia is analyzed. The landings increase contributes to the export increasing, but other factors are likely to be the main drivers of the export growth. This information on quantitative structure of the national annual catch could be used in economical forecasts and for developing of programs and strategies for the fishery industry of Russia. Examples of its practical using for solving of some applied problems in the economics are presented.

Published: July 2019

The design of Metal-Organic Frameworks (MOFs) incorporating electroactive guest molecules in the pores has become a subject of great interest in order to install additional electrical functionalities within the framework while maintaining porosity. In this direction, understanding the charge-transfer (CT) process between the framework and the guest molecules is crucial towards the design of new electroactive MOFs. Herein, we present the encapsulation of fullerenes (C60) in a mesoporous tetrathiafulvalene(TTF)-based MOF. The CT process between the electron-acceptor C60 guest and the electron-donor TTF ligand is studied in detail by means of different spectroscopic techniques and density functional theory calculations. Importantly, gas sorption measurements demonstrate that sorption capacity is maintained after encapsulation of fullerenes, whereas the electrical conductivity is increased by two orders of magnitude due to the CT interactions between C60and the TTF-based framework.

Published: July 2019

HPV is the leading cause of oropharyngeal cancers and a few oral cavity cancers with increasing mortality across the globe. The risk factors for oral cancer are well known. Factors like tobacco chewing, smoking, alcohol consumption and actinic radiation have been extensively studied and clinically validated. However , Recently HPV has been shown to be a significant risk factor for oral and oropharyngeal cancers. The HPV family contains around 200 strains but it is important to note that only nine out of them are high risk and associated with cancers. Amongst them HPV16 is most strongly related with oral cancer. HPV associated cancers are different from cancers originating from other etiologies and thus , require a novel multidisciplinary treatment approach. The article is a review of Molecular Biology , Risk Factors ,Clinical aspects ,Diagnosis ,and Treatment of HPV associated Oral cancer .

Existencial experience of death in the Ukrainian and English prose works of the interwar decades
Authors: Devdiuk Ivanna
Published: July 2019

The article is devoted to the study of death as an existential phenomenon. The topicality of the research is due to the lack of comparative studies of the problem. Its aim is to comprehend the existential of death in the prose of the Ukrainian and English authors of the interwar decades. The research is made on the material of the works by V. Pidmohylny (“Ostap Sheptala”, “A Story without a Title”) and the novel “Honor” by M. Mohyliansky, “The Painted Veil” by S. Maugham and “To the Lighthouse” by V. Woolf. The subject of the study is the philosophical reflections of the characters as subjective thinkers, in the plane of which the authors’ visions of death are actualized. Theoretical and methodological basis is the concepts of the representatives of the existential philosophy (S. Kierkegaard, M. Heidegger, K. Jaspers, A. Camus), in which death is seen as the basic existential of human existence. The main heroes’ attitude to death is considered in the plane of distinguishing of death as an event and as a boundary situation or a phenomenon of death and a phenomenon of mortality. In the course of the study, it was found that an important prerequisite for acquiring thanatological experience by the personages is ‘the death of Another’, which gives rise to a sense of guilt, inducing the personages to active actions. For Ostap Sheptala, Horodovsky, Kitty, Mr. Ramsay, a direct meeting with the death of close people means a boundary situation in which the existence of their own finitude is revealed, which is the main factor in their becoming as individuals as well as in gaining freedom. Instead, in the images of Kalin and Walter, who are in the captivity of their own ambitions, the perception of the ‘death of the Other’ is represented as an objective fact. Their suicide is a consequence of despair, caused by the awareness of their own weakness, which leads to a rejection of oneself. The last is considered as one of the forms of evasion from death. Common for the characters as the spokesman for authors’ views is the state of alienation and loneliness caused by the dehumanization of post-war reality. Prospects for further studies are seen in the study of the problem through the prism of archetypal criticism, as well as the expansion of the arsenal of investigated works.

Jakarta as the capital of the country has a lot of buildings. The number of multi-story buildings with a height of more than nine floors reaching more than 700 buildings. Meanwhile, Jakarta is also not free from the threat of earthquakes. According to the Ministry of Public Works, Jakarta was in zoning with moderate seismicity level. However, it does not avoid the possibility of the occurrence of large earthquakes, i.e. to the level of 2500 year earthquake. A seismic level of 500 years of occurrence probability would produce an earthquake tremor in Jakarta as large as that felt in Padang in September 2009, which is around MMI VII to VIII. Therefore, it is necessary to study the vulnerability of high-rise buildings in Jakarta in the face of the threat of earthquakes, so as to assess the level of the risk.Jakarta sebagai ibukota negara memiliki banyak sekali gedung bertingkat. Jumlah gedung bertingkat dengan ketinggian lebih dari sembilan lantai mencapai lebih dari 700 gedung. Sementara itu, Jakarta juga tidak lepas dari ancaman gempabumi.

Landslides have occurred in various places in Indonesia. Likewise with West Java, there were many regions that has experienced repeated landslides. Having many experience of occurrences of landslides, we should have had a good landslide risk reduction program. Indeed, the incidence of landslides depends on many variables. Due to that condition, it may that a region would have different variable with another region. So it is impossible to generalize the implementation of a mitigation technology for all areas prone to landslides. Research of the Cililin's landslide is to anticipate the next disasters that may happen in around the area of 2013 Cililin Landslide. Through observation lithological conditions, water condition, land cover and landscape, as well as consideration of wide dimension of the building footing, the distance of building to the slopes and so forth, it has been determined some efforts of disaster risk reduction in the area around the landslide against the occurrence of potential landslide in the future.Bencana tanah longsor telah terjadi di berbagai tempat di Indonesia. Demikian halnya dengan Jawa Barat, tidak sedikit daerahnya telah berulang kali mengalami longsor. Seharusnya dengan telah banyaknya kejadian longsor, kita mampu mengupayakan program penurunan risiko longsor secara baik. Memang kejadian longsor bergantung pada banyak variabel, dimana dari satu daerah dengan daerah yang lain akan sangat memungkinkan mempunyai variabel yang berbeda, sehingga tidak mungkin kita membuat generalisasi penerapan suatu teknologi mitigasinya untuk semua daerah rawan longsor. Penelitian longsor di Cililin dilakukan untuk mengantisipasi terjadinya bencana di sekitar daerah Longsor Cililin 2013 yang lalu. Melalui pengamatan kondisi litologi, keairan, tutupan lahan dan bentang alam yang ada, serta pertimbangan akan dimensi luas pijakan bangunan, jarak batas bangunan dengan lereng dan lain sebagainya, telah ditentukan beberapa upaya penurunan risiko bencana di daerah sekitar longsor terhadap potensi kejadian longsor dimasa mendatang.Keywords: Landslide, risk reduction, footing of building, Cililin

Assessing the Environmental Implications of Industrialized Housing: a Systematic Literature Review
Authors: Kedir Firehiwot , Hall Daniel
Published: July 2019

Industrialized Housing (IH), also referred to as prefabrication, preassembly, modularization, and/or off-site fabrication, is a growing strategy for constructing housing. IH offers potential for significant reduction of environmental impact in comparison to traditional housing construction. Past research used methods such as environmental impact assessment on given case study buildings or expert’s opinions to identify the benefits and drawbacks present on the lifecycle of houses constructed partially or fully using IH methods. Nevertheless, this literature is scattered across several sources and units of analysis. The specific factors of IH that contribute to environmental impact reduction have not been comprehensively reviewed and summarized from design considerations up to the end of life possibilities. In this paper, a systematic literature review is performed on the environmental implications of the industrialized way of constructing residential buildings. From a review of 49 journal publications, this paper identifies 18 key factors that influence the environmental performance of such residential buildings. These factors are categorized into the following lifecycle phases of the IH process: a) system design, b) material design, c) manufacturing and logistics, d) transportation and assembly, e) Operational phase, and f) end of life. Findings reveal the importance of decisions made in design phases such as choice of materials, which in turn show a snowball effect throughout the phases. A final category – g) support and hindrance of IH - includes a discussion of external factors such as building codes and regulatory policies and their impact on IH performance.
Data Analytics Application for Non-Conformance Reports in a Cabinet Manufacturing Facility
Authors: Mohsen Osama , Mohamed Yasser , Al-Hussein Mohamed
Published: July 2019

Industrialization of building construction through offsite construction and modularization is an effective approach for improving performance of construction projects. In a modular construction approach, building components are produced in a well-controlled factory environment. The components are then delivered to site, in sequence, for installation by site crews. This process reduces construction waste, improves product quality, and minimizes onsite safety incidents. As the market conditions are rapidly changing, the demand for more customized and unique products is increasing. Customers increasingly demand customized dwellings to reflect their cultural tastes and personal preferences. Cabinets in the house, kitchen or otherwise, are building components that constitute a large portion of the visible customization that customers are interested in. This paper focuses on the analysis of records in Non-Conformance Reports (NCRs) at a cabinet manufacturing facility in Alberta, Canada. An NCR record represents a defect in any product that needs a repair or rework; it captures several attributes of the defective part, such as the job number, wood species, stain, the date and time when the record is created, etc. The systematic approach presented in this study employs data analytics to the collection, cleaning, and analysis of the NCR dataset. The dataset is first analyzed as per existing operations. Various data pre-processing techniques, including attribute and instance selection and transformation, are then applied to clean the dataset. The results show that most of the “Rework” results from administrative or product handling errors, while the majority of “Repairs” result from product finishing errors. The impact of repairing the defective parts is discussed, and recommendations to reduce the number of NCRs and thereby enhance the performance of operations are presented.
Toward Community Generation: Energy Simulation and Performance Evaluation of Multi-family Solar PV Settings for Energy-efficient Homes in Edmonton, Canada

Published: July 2019

The integration of renewable micro-generation systems into residential buildings, particularly solar photovoltaic (PV) distributed energy generation, is emerging rapidly as an effective method of mitigating the housing impact on greenhouse gas emissions. However, the application of solar PV micro-generation is confronted with several challenges: (a) the average system self-consumption does not exceed 25% in cold-climate regions; (b) most of the energy generated during daytime, peaking in the summer, is exported to the grid; and (c) rebates from the surplus generated energy exported to the grid are at a lesser rate than that of the imported energy. Due to relatively poor economics paralleled with the solar PV application, governments and policy makers envision the value of considering the integration of renewable energy sources at the community level rather than individual behind-the-meter applications, since this strategy can leverage the system self-consumption and increase its social impacts and economics. In this regard, this research aims to simulate and compare the overall performance of two scenarios of a sustainable community of 42 townhouse units. In the first scenario, each unit is connected to a behind-the-meter solar PV system of 3.3-kWp. In the second scenario, all units are connected to a large 140-kWp solar PV system. Historical data from one typical house has been collected (ongoing since 2015). Monte Carlo simulation technique is applied to ensure the stochasticity of the diverse household users. The hourly energy consumption and generation data is simulated using Simphony.NET® simulation engine based on the real-time data collected in Edmonton, Canada. Then, the load-match is identified as well as grid interaction indicators and system economics resulting from both scenarios. Results indicate that the application of community generation can significantly mitigate the imported and exported energy compared with individual behind-the-meter system generation due to the improved system self-consumption.

Stress has been identified as a significant hindrance to construction professional’s performance on site. Unfortunately, stress cannot be eliminated on site, but it can only be managed with different stress coping strategies. Therefore, this study aimed at appraising the strategy adopted by construction professionals for coping with stress. Although past studies have examined strategies adopted for dealing with the stress from two dimensions namely: problem-solving and emotional based stress coping strategies. This study introduced the third dimension and called it acceptance a hybrid of previous dimensions. It also appraised the strategy adopted by construction professionals for coping with stress based on their working experience. Convenience sampling method was used in gathering data from selected construction professionals in Lagos state Nigeria. A total of 62 questionnaires were obtained from the professionals out of 70 that were distributed. The data were analysed with statistical package for social science (SPSS version 24), using, mean score and Kruskal Wallis test. The findings from the Kruskal Wallis revealed that the strategy for coping with stress coping is dependent on the construction professionals working experience. The study concludes that communication is a crucial element for coping with construction stress. The study recommends that construction firms and project managers should provide opportunities for construction workers to communicate among themselves. The findings from this study will be useful for project managers and construction firms in Nigeria towards ameliorating the adverse effect of stress among construction professionals.

Shear walls are the major components of the lateral-force-resisting system (LFRS) in light-frame wood buildings. With the growing popularity of mid-rise prefabricated light-frame wood construction, engineers need basic design information on the shear walls to design and produce safe structures in case of high winds and earthquakes. The racking resistance of light-frame shear walls depends on many factors, including sheathing and hold-down devices and, most importantly, sheathing-to-framing fastenings. While the performance of nailed shear walls has been studied extensively, and design information is included in the design codes, there is little information on stapled shear walls, specifically in the US and Canada. The cost of staples is significantly less than that of equivalent nails; hence, the use of staples instead of nails would allow cost savings in mass production if they provide sufficient resistance and displacement capacity in the engineered shear walls. This paper presents the results of a pilot study which was focused on the comparison of the performance of nailed and stapled shear walls in laboratory tests under monotonic and cyclic loading in accordance with ASTM E564 and E2126, respectively. Several series of tests were performed on 2.4-m (8-ft) square shear walls with 11-mm (7/16-in) OSB sheathing with various hold-downs and various spacing of sheathing staples and nails on the perimeter of the sheathing panels (5-cm (2-in), 10-cm (4-in) and 15-cm (6-in)) and 19-mm and 10-mm edge distances. The staples were 16-gauge (50-mm (2-in) long with 11-mm (7/16-in) crown). The nails were 8d box steel wire nails (63-mm (2½-in) long with 2.87-mm (0.113-in) diameter). The test results revealed a similar performance of the nailed and stapled shear walls, and the need for careful detailing. Therefore, prefabrication of walls in the factory settings is preferable to the on-site construction to allow the production quality control.
Consequences of the BC Energy Step Code on Offsite Construction
Authors: Wimmers Guido , Conroy Alison
Published: July 2019

In Canada, off-site construction is still the exception rather than the norm when it comes to wood construction. In Europe’s Alpine Region or Scandinavian countries, off-site construction is standard when it comes to wood construction. This paper will focus on the reasons why Canada’s wood construction industry will shift from mainly on-site to mainly off-site construction over the next 10 to 15 years. In countries with relatively demanding requirements on energy efficiency and air tightness, off-site construction has been dominating the market for more than 20 years. British Columbia adopted the BC Energy Step Code in 2017, a roadmap defining the energy efficiency of buildings over the coming years leading up to 2032, when all new construction will be required to be Net Zero ready. It is expected that the National Building Code of Canada will also encourage higher energy performance levels in the near future. Consequently, thermally better-performing envelopes will have to be produced and rigorous air tightness levels will have to be achieved for the sustainability goals given by the province. Envelope assemblies will get thicker, bulkier and heavier to meet these requirements. In this regard, a market shift to a greater amount of off-site construction is likely to be experienced to meet these targets in a controlled environment. This study is exploring the direct and indirect connections between sustainability and energy efficiency requirements given by codes to technical and cost-efficient solutions offered by industry.

The construction industry is known for the high number of accidents occurring within the industry. This is due to the hazardous working processes which have led to severe injuries, disabilities and fatalities. Towards reducing this hazards numerous health and safety regulations have been provided by construction firms in Nigeria. Despite the provision of the regulations hazards and accidents is still experienced on construction sites. Thus, this study appraised the challenges of ensuring compliance with health and safety regulations by construction workers in the Nigeria construction industry. Data were obtained from safety personnel and construction professionals using questionnaires through a convenience sampling method. One hundred and thirty-eight were used for the analysis out of one hundred and sixty-eight that was distributed to the respondents. The questionnaire was analysed using SPSS V 24 adopting Factor analysis and mean item score. The findings clearly show that construction workers compliance to health and safety requirements is below average while the factor analysis shows inadequate safety equipment, low awareness to occupational health and poor compliance to health and safety requirements are the major challenges hindering the compliance rate. The study recommends that implementation of the use of innovative measures and hi-tech devices such as radio frequency identification for effective monitoring of construction workers. It also recommends the involvement of construction workers when making the health and safety policies. This study contributes towards improving the occupational safety experienced on construction sites within the country.

Published: July 2019

Construction is a major industry in Alberta due to its significant contribution to GDP and employment. Poor communication and inadequate information flow can lead to poor performance on construction projects, in terms of cost, schedule, and quality. Construction 4.0 promotes the implementation of modern information technologies to encourage the digitization of the construction industry and its supply chain. Efficient information flow in the construction supply chain is key for enabling Construction 4.0 and improving the performance of construction projects. This study presents the results of a survey on tools currently used in Alberta’s construction industry to exchange information. Results show that Alberta’s construction industry mainly depends on emails, meetings, and phone calls to exchange information among stakeholders. These tools are shown to be inefficient means of communication because of delays they arise in providing information, and because of their limitations in storing and disseminating information, which hinders knowledge creation and innovation.

Published: July 2019

In the construction industry worldwide there is a recognizable gap between academics construction knowledge and its application, and construction knowledge and application as seen in field of practice. In Nigeria, the Quantity surveying profession like other professions in the industry, suffers this same fate. It is based on this that this paper identified the possible factors causing gap between the two divisions. A survey approach was adopted, and questionnaire was used to gather data from construction professionals both in practice and in academics, Ondo State. Data gathered were analyzed using percentage, mean item score and Mann-Whitney U Test. Findings revealed that the major factors contributing to gap are majorly more theoretical knowledge than practical, inadequacy in educational curriculum, slow adoption of innovations and inadequate trained personnel. The two categories of respondents( practicing respondents and those in academics) believes that the most important factor that can help and in bridge the gap between QS in Academics and QS in practice is frequent organizing workshop, lectures and seminars which has been identified by past literature. Openness to new innovations, equilibrium of theoretical and practical knowledge, are the closely following factors. This study contributes to body of knowledge on this subject of discuss.
