Natural vibrations of a beam on stochastic two-layered subsoil with significantly different thickness
Authors: Kaleta Barbara , Różycki Bartosz
Published: August 2020

In this paper the influence of variability of Young modulus of the subsoil layers on the natural frequency of the beam-two-layered subsoil system was analyzed. Assuming the first layer was thinner and more rigid then the second one (10 and 20 times). The calculations were made by using deterministic and stochastic approach. In the stochastic approach, the spatial correlation of Young modulus of the subsoil along the length of both layers was taken into account. Two cases of the correlation were considered, i.e. without and with full correlation. Regarding the results of the authors’ research which were published in the previous article, in the calculations the full stochastic correlation of Young modulus of subsoil between both layers was taken into account. In order to solve the stochastic eigenvalue problem, Monte Carlo simulation techniques with Finite Element Method (FEM) were used. The present analysis is a continuation research demonstrated in the authors’ previous papers.
FRP composite materials strengthening of flat steel elements
Authors: Łagoda Marek , Kowal Maciej
Published: August 2020

The article describes the study on the impact of FRP composite materials strengthening of flat steel slab. The influence of changing of bond end geometry on three point bending behavior of flat steel elements reinforced by CFRP patch has been investigated. A bond failure at steel-adhesive interface was a dominant failure mode. The test results showed clearly that geometry change of the bond end of strengthening CFRP plate and adhesive can significantly increase bond capacity. The use of reverse taper of CFRP patch with adhesive fillet tapes can improve the load capacity of the adhesive joint on the bending of the flat steel element reinforced by FRP patch. Conclusions and plan of further works on steel elements CFRP strengthening were described.

Static work of scaffolding loaded by actual and standards driven wind forces
Authors: Jamińska Paulina
Published: August 2020

This paper presents static analyzes of scaffolding loaded by wind according to Eurocode recommendations and on the basis of computer simulations of air flow around a rectangular building with a scaffolding assembled at one of the walls. On the basis of calculations performed for the scaffold at different angles of wind attack, the maximum values of the stress in the vertical elements of the framework and in the braces are showed, as well as axial forces in the anchors. In addition, critical buckling load analyses were also performed. The comparison indicates that the forces coming from the actual wind loads differ significantly in direction, sense and magnitude from the forces prescribed in the standards. Underestimated wind load can lead to the state of exceeded capacity in scaffolding elements, and consequently to the construction disaster.

The properties of bitumen with different modifiers after a short-term aging process
Authors: Iwański Marek , Cholewińska Małgorzata , Mazurek Grzegorz
Published: August 2020

The aim of the study was a comparative feasibility studies of the influence of modern modifiers (Trinidad , Gilsonit , synthetic wax , adhesive agent ) for incorporating them to the bituminous mixture at low temperatures production. The bitumen of penetration grade 35/50 was used as reference binder. The effect of modifiers on bitumen behaviour was assessed by means of followed properties: penetration grade, softening point temperature and the breaking point temperatures. Measurements of the above properties have been carried out before and after simulated aging according to RTFOT. Modifiers were dosed in five variants to bitumen by weight. Modification of bitumen with synthetic wax increased the level of bitumen stiffness while the use of the fatty amine did not invoke significant changes in bitumen properties (regarding neat bitumen). Short-term aging significantly influenced on characteristics of bitumen, as well. The highest bitumen change rate after aging was observed in the case of the use of natural bitumen. It was found that the most preferred modifiers to paving bitumen 35/50 were a synthetic wax and a adhesive agent. It is expected that they allow to ensure the durability of bituminous mixtures produced at reduced temperatures.

Overpasses in Poland – naturalists and road constructors’ joint success
Authors: Kurek Rafał , Ślusarczyk Radosław
Published: August 2020

Overpasses in the form of viaducts over roads are among the most interesting engineered facilities. Though building overpasses for animals in Poland has a fairly short history and at the beginning was far from successful, currently we are an European leader in terms of building these objects. The first overpasses built in Poland in 2001 were so narrow and poorly developed that they resembled more the facilities for pedestrians than those supposed to hold an ecological function. As a result of the criticism that came from naturalists, and the interbranch consultations that started at that time, effective measures were implemented within barely few years. The facilities designed nowadays are just as good as the best wild­life crossings in Western Europe. It is noteworthy how important the intersectoral cooperation between the road industry and naturalists has proved to be – mutual substantial support, promoting optimal solutions and sharing experience. This paper will discuss the evolution that took place in Poland between 2001 and 2013 in terms of designing and constructing overpasses. The best road sections and model wildlife crossings that should become an inspiration for designing new facilities will be presented. The author will also analyze the problems the wildlife crossings designers will have to confront over the next few years.
Natural assets in the right-of-way of A-4 Motorway in the Góra Świętej Anny Landscape Park, Opole Region
Authors: Spałek Krzysztof , Mleczko-Król Maria
Published: August 2020

Construction of the A-4 Motorway section in the Opole Region begun in Summer 1997. Very soon vigorous resistance of ecological NGOs was encountered. The bone of contention was the section of motorway that passes through the Góra Świętej Anny Landscape Park and verges the natural reserve of strict protection Ligota Dolna where rare species of thermophilic plants are sheltered. Between 2011 and 2013 a detailed mycological, geobotanical, floristic and fauna research took place within the right-of-way of the A-4 Motorway section crossing the Góra Świętej Anny Landscape Park in the Opole Region. The survey revealed several rare and protected species of fungi, plants and animals along the road, including the greatest in Poland population of Austrian flax Linum austriacum. The area also harbors the only site of xerothermic grass of Festuco-Brometea class with so many rare and putrefying plant species inside a motorway’s right-of-way in Poland. Given the occurrence of many interesting species of plants and animals in the motorway surrounding it seems justified to establish a system of ecological monitoring, which could provide a range of valuable findings regarding the impact of motorway traffic on surrounding flora and fauna. This knowledge would be very useful for all those involved in construction of next motorways in Poland as well as for a wide circle of interested researchers.

Environmentally friendly material and technological solutions of road pavements
Authors: Radziszewski Piotr , Kowalski Karol , Sarnowski Michał , Pokorski Piotr
Published: August 2020

In recent years road construction is a subject of dynamic changes. The main challenge for designers and technologists is to develop durable and environmental friendly road technologies that can be successfully applied on natural valuable areas. The paper presents selected modern material and technological solutions used for road pavements on areas under special protection (eg Natura 2000). An example of modern environmentally friendly solutions in road construction are: asphalt pavements with the addition of rubber from used car tires, asphalt mixtures with reduced emissions of volatile substances, “quiet” pavements, pavements from recycled materials and from local materials, “biologically active” pavements (permeable mineral layers). Modern and ecological pavements are the important part of science activity of Warsaw University of Technology. New ongoing project is designed to identify the main directions of technological development of road construction in the next 30 years, with a particular emphasis on the sustainable development and environmental protection. As a part of the two ongoing projects, test sections of pavement have been completed. One of test sections with the addition of crumb rubber and the second one as a “quiet” pavement. For the next years, the sections will be monitored.The proper selection of materials and technologies on natural valuable areas does not deteriorate the durability of road pavement, comfort and safety on the roads and at the same time it can improve environmental safety without interfering with the functioning of valuable ecosystems.

Contemporary symbols in the space of Baku
Authors: Kaczmarska Elżbieta
Published: August 2020

When performing even a cursory analysis of the visual image of contemporary Baku, the capital of Azerbaijan, one simply cannot ignore its ancient history, the political influence of nearby powers and the almost age-old dependence on Soviet Russia. The regaining of independence in 1991, associated with the policy of then-national leader Heydar Aliyev, stimulated the young country’s ambition to open up to the world and organise an international cultural event. The preparation for the Eurovision Song Contest in 2012 initiated another construction boom in the history of Baku, fuelled with petrodollars, and became an occasion to present a new vision of the capital. In the years 2007–2012, numerous new cultural, artistic and sports buildings were constructed and which are now a hallmark and symbol of contemporary Baku. One such building, which creates a new, futuristic city space and is presented in the article, is the Heydar Aliyev Centre, a centre of art and museum designed by Zaha Hadid. The author notes the creative intent, external appearance and structure of the building, as well as new means of expression in creating place-based ambience. Also noted were the use of contemporary art in the creation of attractive utilitarian spaces. Other presented buildings display the ages-old symbols of the ‘Land of Fire’ in a new way and are embedded into the contemporary panorama of the city

Some examples of the improvement are the improvement in conditions, degrees, and quality of life of women in various strategic sectors such as education, employment, economy, health, and family planning participation. Improvement in the empowerment process does not necessarily change the pattern of gender relations between men and women. To improve gender equality in the economy, women's economic actors need to be empowered. The purpose of this study is to examine the appropriate empowerment model for women in the informal sector. This is a case study involving observation, interviews, and Focus Group Discussion. The results of the study showed that women in the informal sector are not yet independent even though they have obtained facilitation from the government. The absence of government’s assistance in managing business resulted in the limited empowerment activities carried out by the government. This research offers a model of economic empowerment for women towards independence in economic activities.

independence and empowerment of fisherwomen in Tanjung Batuq Harapan Village. The data sources were the Head of Muara Muntai Sub-district, the Head of Tanjung Batuq Harapan Village, fisherwomen, and villagers. The data were analyzed through several stages involving collection, data reduction, data presentation, and conclusions. The results of the study indicated that the independence and empowerment of fisherwomen in Tanjung Batuq Harapan Village were not optimally implemented. This could be seen through the fact that women multitasked themselves as wives who had to take care of their husbands and children as well as the breadwinners of their families. Meanwhile, the husbands' roles were mostly earning money for living with less attention to domestic matters. Nevertheless, the majority of fisherwomen in Tanjung Batuq Harapan were widows who felt marginalized by the infrastructure in their village.

The quality of various domains in life leads to life satisfaction which is essential for a balanced existence. From the perspective of physical and mental health, family, education, employment, wealth, safety & security to freedom, religious beliefs and the environment –all entities of a human life are involved to it. Attempt has been made to consider three major aspects of a quality life namely, mindful eating, physical activity and sleep hygiene to denote the status of behavioural habits of people living in India and Canada. 373 subjects, 234 from India and 139 from Canada, were selected conveniently for this study. It is observed that Canadian community is significantly superior in habits of mindful eating and physical activities in comparison to Indian subjects. However, no significant difference was found in sleep hygiene between the subjects living in India and Canada.

Selecting proper candidate materials is one key issue for the development of the supercritical water-cooled nuclear reactor (SCWR). Designing or choosing the most fitting materials means better sustainability, economics and safety. As the supercritical water is a very aggressive corrosive media, corrosion becomes one challenging problem for the materials used in the SCWR. This paper involves the corrosion testing of two stainless steels (304L and 310S) and microstructure evaluation of samples after being exposed to supercritical water. The test parameters were set at the temperature of 550oC and the pressure of 25 MPa for up to 63 days. The samples were investigated using gravimetric corrosion test, optical microscopy, scanning electron microscopy coupled with energy dispersive X-ray spectroscopy. Results showed a lower corrosion performance, in terms of weight change and surface oxide formation, for 304L due to its low chromium content. 310S has excellent corrosion resistance because the chromium content is higher. The results obtained will be useful in future research of test protocol and development of alloys that could be used as reactor fuel cladding and other components in the SCWR.

This study was conducted to explore the production of magnesium oxide from raw salt solution using electrochemical precipitation, followed by calcination. Electrochemical precipitation was conducted by electrolysis of the salt solution using nickel rods as cathodes and graphite as anodes. Two sets of salt solutions were prepared: one set without pretreatment and another with BaCl2 pretreatment. The solutions were used to study the effect of salt concentration, potential, and electrolysis time. The representatives of the MgO produced were tested as catalysts for transesterification of coconut oil. The results indicate that optimum mass of precipitate was produced from 400 mg/L salt solution electrolyzed using 8 V for 60 min. Elemental analysis using X-Ray Fluorescence (XRF) revealed the presence of Mg as the main component of the precipitate, confirming the electrochemical conversion of Mg2+ into solid Mg(OH)2. The MgO with the purity of 74.23% and 88.87% was produced from non-pretreated and pretreated salt solution, respectively. The transesterification experiments indicate that the yield of 90% and 98% was achieved using the MgO produced from non-pretreated and pretreated salt solution, respectively.

The methodology of the amino acid lysine (Lys) analysis using ninhydrin (Nin) reagent by spectrophotometric method was in-depth studied and improved. The optimization of time, Lys to Nin volume ratio and temperature were explicitly investigated. A specific wavelength of 479 nm was set according to the peak of the absorbance spectrum. The reaction time between Lys and Nin, in aqueous solution, occurs during 50 min. The Lys/Nin ratio 1.67 appeared most effective for this reaction. Moreover, the absorbance increased with temperature until a stable value was achieved nearly at 85�C. It was also found that the reaction is more efficient at initial pH 6 corresponding to formation of high amount of coloured product. Furthermore, the pH of post-reaction mixture was around 4 for different concentrations of lysine and initial pH range 3�10. For lysine solution contaminated with potassium (a representative interfering species) and after variation of the reaction conditions, the maximum wavelength (479 nm) was not affected. Mastering the use of these parameters leads to a good usage of this analytical technique which is simple, fast, accurate, less expensive and especially less harmful towards the environment and human health.

The main purpose of this study was to identify the types of water and other drinks used for hydration by those who perform movement activities and also to analyze the quality of these drinks. As a result of performing movement activities, through perspiration, a greater or lesser amount of water is lost from the body. Along with this, a number of nutrients are lost. Given these aspects, the main objective of the research was to understand more correctly, what is involved in proper hydration, which are the factors that must be taken into account to maintain good health. We analyzed and compared the level of the main electrolytes and carbohydrates for different categories of drinks and also measured with the help of two specific devices the level of purity and pH of three categories of drinking water. We indicated general values regarding the ratio of water consumption to weight on the one hand, and on the other hand, we indicated the indicative quantities that should be consumed before, during and after performing medium-level physical effort. As a general conclusion, the importance of sodium, alkaline water and high water purity was highlighted in relation to the categories of beverages analyzed in this study.
Changes of Neuropathy Target Esterase Affect Phospholipid Homeostasis in SK-N-SH Cells
Authors: Yu-Yuan Li , Yi-Jun Wu
Published: August 2020

Neuropathy target esterase (NTE), is a membrane protein located in the endoplasmic reticulum (ER). NTE has the activity of phospholipase B and can catalyze the deacylation of phosphatidylcholine (PC) and lysophosphatidylcholine (LPC) to glycerylcholine (GPC). It is phosphorylated and aged by organophosphorus compounds (OPs), that induce delayed neuropathy in humans and sensitive animals. Our previous study has reported that the disruption of ER phospholipid homeostasis caused by the NTE inhibition may contribute to the initiation of the organophosphate-induced delayed neurotoxicity (OPIDN), while it is unknown how the disturbed phospholipid homeostasis initiates OPIDN. It is difficult to change phospholipids in in vivo experiments. Therefore, an in vitro model is urgently needed to explain the role of phospholipid homeostasis disorders in OPIDN. In this study, we altered the expression of NTE in SK-N-SH cells and determined its phospholipid component by using HPLC-MS. Our results showed that the changes of NTE affected the levels of PC, sphingomyelin (SM), phosphatidylethanolamine (PE), phosphatidylserine (PS), lysophosphatidylserine (LPS), phosphatidyl-glycerol (PG), and phosphatidylinositol (PI). Our results were consistent with the in vivo results. Furthermore, our findings indicate that the SK-N-SH cell model is a significantly useful method for the further research on how the changes of phospholipid homeostasis initiate the OPIDN, which is easier than the in vivo experiments in practice.
The Asymptotic Behavior of Solutions of a Fractional Integro-differential Equation
Authors: Ahmad Ahmad M.
Published: August 2020

In this paper, we study the asymptotic behavior of solutions for an initial value problem with a nonlinearfractional integro-differential equation. Most of the existing results in the literature assume the continuity of theinvolved kernel. We consider here a kernel that is not necessarily continuous, namely, the kernel of the RiemannLiouville fractional integral operator that might be singular. We determine certain sufficient conditions underwhich the solutions, in an appropriate underlying space, behave eventually like power functions. For this purpose,we establish and generalize some well-known integral inequalities with some crucial estimates. Our findings aresupported by examples and numerical calculations.
