Differences in Electricity Generation from Renewable Sources from Similar Environmental Conditions: The Cases of Spain and Cuba
Authors: González Lorente Álvaro , Hernández López Montserrat , Martín Álvarez Francisco Javier , Mendoza Jiménez Javier
Published: June 2020

In order to achieve the objectives set by the Sustainable Development Goals and the Paris agreement, the legislative framework that is developed at the national and regional level must be appropriate. Research has focused on the importance of environmental policies to stimulate renewable energy demand and has also highlighted the existence of legal regimes more inclined to preserve the current model of dependence on fossil fuels. The main aim of this paper is to observe the impact of different regulation framework in the use of renewable energies in electricity generation. The choice of Spain and Cuba was based on several reasons: first, they present different models of legal regulations for renewable energies, with more centralized power in the case of Cuba and more influence of supranational institutions in the case of Spain; second, they have similarities regarding their productive model (highly dependent on hydrocarbons as sources of electricity generation) and the high potential for electricity generation with renewable energies thanks to their rich natural endowment that could favor energy generation from sources like the sun, wind and water; finally, both countries face a global situation where they could take advantage of this cost-cutting moment, and therefore, of electricity tariffs, to propose a sustainable model of electricity generation based exclusively on renewable energies. The conclusions show that Spain can become a role model to improve the Cuban system, given that the European and Spanish “green” positions can be very useful in developing Cuba’s future energy model based on renewables. The existing ties between the Caribbean country, Spain and the European Union (EU) should be the basis to support a model for which Cuba has an outstanding endowment of natural resources and where the similarities with Spain can generate synergies based on the European experience.

Published: June 2020

This paper presents relationships between personality traits and stress levels in light of the transactional model of stress. The framework of the transactional model was applied to determine the significance of work with a robot for primary and secondary stress appraisal made by an individual. We decided to use the Big Five personality traits model as one which integrates the dimensions of personality and had been previously applied to research on stress. The participants in our three-wave study were 105 students doing an industrial robots programming course. Using Ten Item Personality Inventory (TIPI) and Questionnaire for Primary and Secondary Appraisal (PASA) questionnaires, we gathered information about the students’ personality, the level of anticipated stress, and the stress experienced while working with a robot after 6 and 12 weeks. The obtained results prove that emotional stability is significant for secondary appraisal of anticipated stress. The results also show that openness to experience is a negative predictor, whereas conscientiousness is a positive predictor of primary stress appraisal. The ability to cope with stress after 12 weeks of work with a robot is appraised as higher by older, more conscientious, and introverted people. The obtained results are discussed from the psychological perspective of stress and personality, which complements earlier studies in technical sciences. The limitations of the study are also indicated.
Type A Trichothecene Diacetoxyscirpenol-Induced Emesis Corresponds to Secretion of Peptide YY and Serotonin in Mink

Published: June 2020

The trichothecene mycotoxins contaminate cereal grains and have been related to alimentary toxicosis resulted in emetic response. This family of mycotoxins comprises type A to D groups of toxic sesquiterpene chemicals. Diacetoxyscirpenol (DAS), one of the most toxic type A trichothecenes, is considered to be a potential risk for human and animal health by the European Food Safety Authority. Other type A trichothecenes, T-2 toxin and HT-2 toxin, as well as type B trichothecene deoxynivalenol (DON), have been previously demonstrated to induce emetic response in the mink, and this response has been associated with the plasma elevation of neurotransmitters peptide YY (PYY) and serotonin (5-hydroxytryptamine, 5-HT). However, it is found that not all the type A and type B trichothecenes have the capacity to induce PYY and 5-HT. It is necessary to identify the roles of these two emetogenic mediators on DAS-induced emesis. The goal of this study was to determine the emetic effect of DAS and relate this effect to PYY and 5-HT, using a mink bioassay. Briefly, minks were fasted one day before experiment and given DAS by intraperitoneally and orally dosing on the experiment day. Then, emetic episodes were calculated and blood collection was employed for PYY and 5-HT test. DAS elicited robust emetic responses that corresponded to upraised PYY and 5-HT. Blocking the neuropeptide Y2 receptor (NPY2R) diminished emesis induction by PYY and DAS. The serotonin 3 receptor (5-HT3R) inhibitor granisetron totally restrained the induction of emesis by serotonin and DAS. In conclusion, our findings demonstrate that PYY and 5-HT have critical roles in DAS-induced emetic response.
BLI-Based Functional Assay in Phage Display Benefits the Development of a PD-L1-Targeting Therapeutic Antibody

Published: June 2020

The therapeutic functionality of the antibodies from phage display is verified after an initial screening. Several immunological assays such as ELISA, flow cytometry, the western blot, and surface plasmon resonance (SPR) assay are commonly used; the IgG-format antibody is usually preferred to verify the functionality of antibodies, which need elaborative mammalian expression and purification work. Here, we describe a biolayer interferometry (BLI)-based assay that can evaluate the inhibitory functions of antibodies at an earlier stage of screening. To develop a PD-L1-targeting antibody from phage display, we applied the BLI assay to the initial scFv antibody screening, in addition to common ELISA and fluorescence-activated cell sorting (FACS) assays, which showed high advantages and relevance with the in vitro cell-based PD-1/PD-L1 inhibition assay. The same assays for IgG-format antibodies showed high efficiency of the BLI assay in the functional characterization of antibodies, and one candidate selected from the BLI assay resulted in highly efficacious antitumor activity in an in vivo syngeneic mouse study. The BLI assay was also beneficial when searching for antibodies with diverse epitopes. These results demonstrated that the BLI-based inhibition assay is an excellent technique for high-throughput scFv antibody screening in earlier stages and can make phage-display antibody screening more efficient to develop therapeutic candidates.

Published: June 2020

Many studies have attempted to predict chlorophyll-a concentrations using multiple regression models and validating them with a hold-out technique. In this study commonly used machine learning models, such as Support Vector Regression, Bagging, Random Forest, Extreme Gradient Boosting (XGBoost), Recurrent Neural Network (RNN), and Long–Short-Term Memory (LSTM), are used to build a new model to predict chlorophyll-a concentrations in the Nakdong River, Korea. We employed 1–step ahead recursive prediction to reflect the characteristics of the time series data. In order to increase the prediction accuracy, the model construction was based on forward variable selection. The fitted models were validated by means of cumulative learning and rolling window learning, as opposed to the hold–out technique. The best results were obtained when the chlorophyll-a concentration was predicted by combining the RNN model with the rolling window learning method. The results suggest that the selection of explanatory variables and 1–step ahead recursive prediction in the machine learning model are important processes for improving its prediction performance.
EXPERT STUDY TO DETERMINE THE MARKET VALUE OF WATERCRAFTS AND ITS COMPONENTS IN FORENSIC PRACTICE
Authors: Ruvin O. , Matveiv V.
Published: June 2020

The article is devoted to the problems of one of the types of forensic transport and commodity examination on the value of water transport, namely, watercraft.

The fast pace of saturation of the consumer market of Ukraine with such means occurs both due to domestic official certified manufacturers, as well as due to amateur activities, illegal production, smuggling of imported shipping means into the customs territory of Ukraine. The expansion of their assortment leads to the fact that they become the objects of forensic examination.

Processes such as the transition of society to market economic, the privatization of state and communal property, the development of insurance activities, changes in legislation, force investigators, judges, bailiffs to raise issues related to the right of ownership. And the use of water transport for forensic examination with cases of falsification, fraud, incompetence of certain officials, determination of the actual market value of these objects during shifts of the owner (ownership distribution), imperfection of our legislation and so on.

All of the above emphasizes once again the complexity research of water transport objects, especially when they are conducted only on the case and up on the last date. Commodity examination and research to determine the market value of water transport cannot exist separately, without technical research, and is quite a challenge for the expert. This is due to the following factors: the lack of valuation methodologies for both large and small vessels as a whole, limited price information in open sources.

Expert practice regarding the assessment of water transport indicates that such examinations and all areas require a broad development and scientific and methodological approach, since the process of researching water transport is quite complex, diverse and specific, given that, recently, pre-trial investigation authorities, courts are increasingly turning to the Kyiv Scientific Research Institute of Forensic Expertise to resolve issues.

At present, a large number of different research have been conducted at the Kyiv Scientific Research Institute of Forensic Expertise, many examples have been collected, and key points of examination of water transport have been identified. In the light of the above experience, to ensure the scientific validity of the answers to the questions put to the experts, work is underway to develop a methodology for expert value of water transport.
THE CURRENT CONDITION OF HOME VIOLENCE ISSUES AGAINST WOMEN IN UKRAINE AND FORENSICS ASPECTS
Authors: Babkina O. , Tkachov A.
Published: June 2020

The article is devoted to the analysis of the aspects of providing legal assistance to women victims of domestic violence in Ukraine. Due to our analysis, we have demonstrated that in Ukraine, legislative documents have been developed at the legislative level to prevent domestic violence and the observance of women’s rights, and forms of domestic violence have been identified (psychological, physical, sexual). The main standards of the regulatory framework of Ukraine are consistent with the Istanbul Convention. In practical work, law enforcement agencies interact with social services, medical institutions, forensic medical examinations and many others to provide timely, fullfledged assistance to women in cases of detected domestic violence, and in each case develop a system of measures to prevent, promote and prevent domestic violence.

A positive aspect in the modern legislation of Ukraine was the establishment of restrictive measures for persons who committed domestic violence in the form of a ban on staying in a place of cohabitation with a person who suffered from domestic violence; prohibitions of approaching a place or person who has suffered from domestic violence, etc. Attention is drawn to the fact that for the first two violations, the person who committed domestic violence can be held administratively liable, and for the third time, criminal liability.

Recommendations are given on conducting a forensic examination in cases of domestic violence against women, in which, in addition to the mandatory points reflected in the Rules for the Examination of Victims, Accused and Other Persons, aspects of an ethical approach are noted to reduce the psychological trauma of women during examination.

It was emphasized that the issue of beatings, torment and torture falls within the competence of the bodies of pre-trial investigation/court and is not the competence of forensic medical examination.
METHOD OF PREPARING CYTOLOGICAL PRODUCTS USING AN ULTRASONIC BATH
Authors: Starovoitova R. , Druchinina I.
Published: June 2020

The article presents a new technique for the preparation of cytological preparations, which can significantly increase the yield of cellular elements from traces of biological origin on material evidence. The use of this technique increases the percentage of positive results when conducting forensic cytological studies.

The study found that the use of an ultrasound bath in forensic examination of cigarette butts increases the number of cells removed by an average of 5-7 times compared to the conventional method of preparation of cytological drugs.

The analysis of the data also indicates that the storage time of cigarettes in the laboratory does not significantly affect the amount of cellular element extraction. Some difference in the average number of cells, for example, the shelf life of 1 month and 3 months, can be explained by the “dry” way of smoking cigarettes.

The use of this method in the examinations showed that ultrasound treatment does not affect the further investigation of these deficiencies in order to identify the antigens of the ABO system and to establish the category of excretion of smokers.

The application of this method makes it possible to use much less material in the examinations, and treatment with saline solution allows to save the biomaterial for further research by the method of DNA analysis.

Thus, the use of an ultrasound bath for the preparation of cytological preparations for cigarette butts can be recommended to forensic experts-cytologists for practical work, which will significantly increase the percentage of positive results in establishing the sex of saliva on these objects.

Published: June 2020

The aim of this study was a characterization of the crystals of gold complexes based on mercaptotrazole, obtained from solutions with different pH values (2, 4, 7, and 9), using the methods of infrared (IR) and Raman spectroscopy. Both methods provided very useful information on the investigated systems and signalized existence of the Au-S bond in the complexes obtained at pH = 2 and 9. Recorded spectra clearly illustrated the changes that occur in the systems as a consequence of pH change. At the same time, the results also showed that the pyrrole nitrogen atoms stay protonated at pH = 9, which is not in favor of the assumption evolved from the previous UV-vis analysis of possible additional coordination between Au and possible deprotonated nitrogen atoms at this particular pH.

Keywords: synthesis; gold-mercaptotriazole (Au-MT); IR and Raman spectroscopy

Published: June 2020

In this work, we present a versatile surface engineering strategy by the combination of mussel adhesive peptide mimicking and bioorthogonal click chemistry. The main idea reflected in this work derived from a novel mussel-inspired peptide mimic with a bioclickable azide group (i.e., DOPA
4
-azide). Similar to the adhesion mechanism of the mussel foot protein (i.e., covalent/noncovalent comediated surface adhesion), the bioinspired and bioclickable peptide mimic DOPA
4
-azide enables stable binding on a broad range of materials, such as metallic, inorganic, and organic polymer substrates. In addition to the material universality, the azide residues of DOPA
4
-azide are also capable of a specific conjugation of dibenzylcyclooctyne- (DBCO-) modified bioactive ligands through bioorthogonal click reaction in a second step. To demonstrate the applicability of this strategy for diversified biofunctionalization, we bioorthogonally conjugated several typical bioactive molecules with DBCO functionalization on different substrates to fabricate functional surfaces which fulfil essential requirements of biomedically used implants. For instance, antibiofouling, antibacterial, and antithrombogenic properties could be easily applied to the relevant biomaterial surfaces, by grafting antifouling polymer, antibacterial peptide, and NO-generating catalyst, respectively. Overall, the novel surface bioengineering strategy has shown broad applicability for both the types of substrate materials and the expected biofunctionalities. Conceivably, the “clean” molecular modification of bioorthogonal chemistry and the universality of mussel-inspired surface adhesion may synergically provide a versatile surface bioengineering strategy for a wide range of biomedical materials.

Multibeam spherotron
Authors: Kurayev A. A. , Matveyenka V. V.
Published: June 2020

The article proposes two types of multibeam spherotron-diotron based on a two-spherical resonator (an early article suggested a spherotron-diotron with non-synchronous interaction on a bi-spherical resonator, where the electron beam in this generator passes along the resonator z axis from the outer sphere to the inner one and interacts with the longitudinal (axial) electric resonator field). The first spherotron type has electron beams going from outer to inner sphere with slope ϧ about the z-axis: ϧ=0, π/8, π/4. The electrons interact with the resonator field through the emergence of quadratic forces in the field increasing along the electron motion. The second type (inverted spherotron) has electron beams located in half arc of the equatorial resonator plane, and the electrons move from the inner sphere to the outside. The interaction in it is carried out due to the spatial electron phasing. Both spherotron types achieve efficiency of 30 % at ultra-high pulse power and tens of kuloampère of total beam currents. The data presented in the article indicate the prospects of broad application for the inverted spherotron by the following indicators: extreme ease of design; no precision gratings or combs are required with a step significantly shorter than the wavelength; no focusing magnetic systems are required; electronic efficiency from 26 to 45 % is ensured. Note that the spherotron is fundamentally a highpower device (10-100 MW in a 1-10ns pulse) for in order to maintain the efficiency of non-synchronous interaction, one needs a high strength of the electromagnetic field, which is achieved only with a high-power device.

Published: June 2020

At present, the field of applications of powerful ultrasound is expanding intensively, and the improvement of equipment and technological processes continues. With that, the key factor in the effect of ultrasonic vibrations on processes in liquids and liquid-like media is cavitation, i.e. the phenomenon of formation, pulsation and collapse of gas microbubbles under the influence of variable pressure. The widespread introduction of promising ultrasound technologies is largely constrained by the fact that the patterns of cavitation generation are not well understood, and the data known in the literature are contradictory and are characterized by low reproducibility. This paper describes an innovative method for studying ultrasonic cavitation. In order to increase the reproducibility of the results and the reliability of the conclusions about the correlation of various cavitation effects, it is proposed to register simultaneously the parameters characterizing these effects. An installation designed to implement this method has been developed and tested. The installation provides the ability to register the full output signal of the hydrophone, the intensity of the glow generated in the cavitation region - sound luminescence, the cavitation noise spectrum and its individual components. Technical characteristics of the installation allow you to adjust the rate of development of the cavitation region by varying the duration and period of the ultrasound pulses. It is possible to conduct experiments both in low-frequency (LF) and high-frequency (HF) fields as well as in interacting HF and LF ultrasonic fields. During the testing of the installation, the results were obtained that are of considerable interest from the point of view of refining the ideas about the mechanism for generating cavitation effects. It was found that preliminary treatment of the liquid in an ultrasonic field with the aim of its degassing for 15–20 min provides a significant increase in the reproducibility of measurements, especially for liquids with a high gas content. Based on a comparison of the time dependences of the signals of the cavitation sensor and the photomultiplier output, the characteristic stages of the development of the cavitation region are distinguished, which differ in the dynamics of the development of the cavitation region and in the composition of the cavitation noise spectra recorded.
Protection against traffic noise in urban areas in relation to noise control plans
Authors: Bohatkiewicz Janusz
Published: June 2020

Exposure to traffic noise belongs to the most harmful impacts affecting people who live in towns. Nearly one third of residents of big towns in Poland suffers from permanent exposure to traffic noise, which may have adverse effects on health. The same refers to most European cities. The problems of noise is regulated by identical legislation in the EU and in Poland. Noise control in big towns arises from regulations related to obligatory provision of noise mapping and noise control plans. The plans contain, among other things, site-specific methods of protection against traffic noise. Those sites are defined by means of the “M” index, whose value is the higher the more people live in the area and the more permissible noise levels are exceeded. The noise control plans prepared to-date contain a range of methods and measures aimed at ensuring protection against traffic noise. In many cases those methods are nothing but improvised response and are not effective enough in towns, for example noise barriers. Results of pilot research indicates that comprehensive physical traffic calming measures may prove to be an effective and long lasting noise control solution in the surrounding of streets in urban areas. Physical traffic calming may be more effective than the measures commonly used so far which does not require additional land acquisition.

Authors: Budzyński Marcin , Jamroz Kazimierz
Published: June 2020

The objective of road infrastructure safety management is to ensure that when roads are planned, designed, built and used traffic accident risks can be identified, assessed and mitigated. There is a number of approaches, methods and tools for road safety infrastructure management. European Union Directive 2008/96/EC regulates and proposes a list of tools for managing road infrastructure safety. The paper presents two of these tools - classification of dangerous sections and control of the infrastructure in the field of safety. The final section presents the necessary directions for further action, particularly scientific research, supporting the management of the existing road infrastructure.
Self-cementing properties of recycled concrete aggregates (RCA) on the example of tests of material and layers of pavement subbase
Authors: Fengier Jakub , Pożarycki Andrzej
Published: June 2020

The work is an attempt to summarize the experience concerning the diagnosis of the practical properties of recycled aggregate concrete cement (RCA). It describes the phenomenon of self-cementing properties which was investigated in both the laboratory and on field tests including compressive strength of RCA, non-conventional oedometric tests of RCA and plate bearing tests on the surface of RCA layer. The described self-cementing properties were remarked, however, the RCA material was characterized by smaller increase in the value of parameter EV2 in a 2-year period of time than recycled concrete materials described in the available literature.
Characteristics of the fatigue life (IT-FT) of the recycled base course at the controlled stresses state
Authors: Iwański Marek , Buczyński Przemysław , Mazurek Grzegorz
Published: June 2020

The paper presents the results of the base coarse made in the cold deep recycling technology with the emulsion in aspect of its durability for a different tensile stress level. The recycled base design simulated a deep recycling process with materials from existing crushed bituminous pavement layers("in-situ" technology). While assessing the quality of the designed MCE mixture, the following physical and mechanical parameters were considered: void contents Vm, indirect tensile strength ITSDRY at 25oC, tensile strength ratio TSR, stiffness modulus Sm. Additionally, the evaluation of fatigue was done at three stress cases: 250 Pa, 400 Pa, 500 Pa. The impact of the vehicle axle load on the stress state in the base course was simulated. For the purpose of determining the pavement durability, one of the method of fatigue life test was used. The tests were done according to IT-FT, based on an indirect tensile test (ITT). This method was choosen because it exhibits good equivalence to the real road pavement behaviour.
Monolayer asphalt pavement. Western requirements in Polish realities
Authors: Koźlarek Piotr
Published: June 2020

Polish road network is made up of 95% local roads. Their technical condition is much worse in comparison to motorways and national roads network. The lack of financial resources is one of the main reasons for this situation. That is why there is a continuous search for technologies, that allow for fast and cheap pavement repair or modernization. The monolayer asphalt pavement is such a solution offering in addition to cost effectiveness and shorter construction time, also an increased durability. Our western neighbors developed the technical regulations for this technology under the name "Asphalttragdeckschicht" which is marked as AC 16 TD. In direct translation "Asphalttragdeckschicht" means supporting wearing course / base layer. The monolayer asphalt pavement consists of a single layer with thickness between 5 to 10 cm made of HMA that links the functions of two layers – asphalt base course and asphalt wearing course. Thanks to this, the monolayer is resistant to environmental conditions and provides an adequate bearing capacity for a given traffic load. Insufficient funding and the impossibility to put the street out of operation were the bases for the investor’s decision to build a 220m section of road pavement using the monolayer pavement technology in Pruszków near Warsaw. This project gave the possibility to learn and gain an experience with a new western technology applied to Polish reality.
Prognosis of the technical condition of masonry walls in residential buildings
Authors: Nowogońska Beata
Published: June 2020

The basis for diagnosis of technical buildings includes information collected by the measurement system and generated by suitable computational procedures. In the case of residential buildings, the parameter describing the symptoms of efficiency / inefficiency of components of a building is defined as the degree of wear, determined during periodic inspections. The degrees of wear of components of a building performed in the same technology. i.e. similar structure-strength systems, and with similar materials are the key figures in the prediction of the reliability of a building.The article presents the methodology of predicting operational reliability of masonry walls. The predictions of the degree of wear for walls, described with the Rayleigh distribution function, have been verified with the assessment of the technical condition of buildings in Zielona Góra.
Geometric shaping of chosen two-layered bar domes
Authors: Pilarska Dominika
Published: June 2020

The covering of large areas, such as sport areas, trade halls, warehouses and others, may be designed by using forms of spherical domes. Such constructions, especially bars ones, have undoubtedly big superiority in comparison to other structures, thanks to their light-weight or easy montage and dismantle system of particular elements. Regular polyhedra may constitute the basis for bar domes generating. Octahedron, one of the mentioned polyhedra, is for the author the basis for consideration the bar structures creation. The geometry and topology of nodes allow for the obtainment of different and interesting forms created on starting regular octahedron. The joint of two one-layered structures, using the jointing-bars, enables to obtain a two-layered structure, which is much more stable. Using different distance between two layers that is using different radiuses R1 and R2 describing spheres of each structure, we can receive models with different geometry. Thanks to that, it is appropriate to analyze different geometry parameters of researched domes. The results can be used by designers as the basis for the proper architectural spherical construction choice.

Published: June 2020

The article in general describes the problems- associated with maintenance of buildings erected in large panel technology and their importance. In particular, the issues of sustainability, safety and comfort of use of buildings erected in the OWT technology in the 80's and 90's were illustrated on the example of the last residential X-storey building built in this technology in Rzeszow, located in one of the housing estates. The building have been monitored by the authors of the paper since 2002. During that time many defects have been successively found and investigated.

Proposed remedial solutions aimed at bringing the building to normal state as well as providing a sense of security and comfort to ensure a good technical state of the building and enhance the residents’ feeling of safety. Some of the solutions have already been implemented, but some are waiting for implementation in conjunction with a thermomodernisation.
