Published: August 2020

An important problem that arises at present refers to the increase in performances in the exploitation of the conveyor belts. Additionally, it is pursued to use some materials, which can be obtained by recycling rubber and PVC waste, in their structure. Thus, the research aimed at creating conveyor belts using materials obtained from the recycling of rubber and PVC waste. Under these conditions, conveyor belts were made that had in their structure two types of rubber and PVC, which was obtained by adding in certain proportions of reclaimed rubber and powder obtained from grinding rubber waste. In order to study the effect of adding PVC on properties, four types of conveyor belts were made, with the structure of rubber, PVC and textile reinforcement. These have been subjected to certain mechanical tests, also being analyzed from the point of view of the behavior of the accelerated aging. The results obtained showed that the addition of PVC lead to a decrease in tensile stress for the strips made, but also an increase in the tensile strain. Additionally, the elasticity tests performed before and after the accelerated aging showed that the presence of PVC in the structure of the conveyor belts determined a substantial reduction of the aging process of the rubber in the conveyor belts. Under these conditions, it has been established that the use of PVC in the structure of rubber matrix conveyor belts is beneficial if conveyor belts are to be produced that are less subject to mechanical stress, but that work in conditions that can cause accelerated aging of materials. An analysis with the finite element method (FEM) of the test samples was also performed.

Published: August 2020

Mixed ionic-electronic conductors, such as poly(3,4-ethylenedioxythiophene): poly(styrenesulfonate) (PEDOT:PSS) are postulated to be the next generation materials in energy storage and electronic devices. Although many studies have aimed to enhance the electronic conductivity and mechanical properties of these materials, there has been little focus on ionic conductivity. In this work, blends based on PEDOT stabilized by the polyelectrolyte poly(diallyldimethylammonium) (PolyDADMA X) are reported, where the X anion is either chloride (Cl), bis(fluorosulfonyl)imide (FSI), bis(trifluoromethylsulfonyl)imide (TFSI), triflate (CF3SO3) or tosylate (Tos). Electronic conductivity values of 0.6 S cm−1 were achieved in films of PEDOT:PolyDADMA FSI (without any post-treatment), with an ionic conductivity of 5 × 10−6 S cm−1 at 70 °C. Organic ionic plastic crystals (OIPCs) based on the cation N-ethyl-N-methylpyrrolidinium (C2mpyr+) with similar anions were added to synergistically enhance both electronic and ionic conductivities. PEDOT:PolyDADMA X / [C2mpyr][X] composites (80/20 wt%) resulted in higher ionic conductivity values (e.g., 2 × 10−5 S cm−1 at 70 °C for PEDOT:PolyDADMA FSI/[C2mpyr][FSI]) and improved electrochemical performance versus the neat PEDOT:PolyDADMA X with no OIPC. Herein, new materials are presented and discussed including new PEDOT:PolyDADMA and organic ionic plastic crystal blends highlighting their promising properties for energy storage applications.

Published: August 2020

The recycling of macromolecular biowastes has been a problem for the agriculture industry. In this study, a novel N, S-codoped activated carbon material with an ultrahigh specific area was produced for the application of a supercapacitor electrode, using tobacco stalk biowastes as the carbon source, KOH as the activating agents and thiourea as the doping agent. Tobacco stalk is mainly composed of cellulose, but also contains many small molecules and inorganic salts. KOH activation resulted in many mesopores, giving the tobacco stem-activated carbon a large specific surface area and double-layer capacitance. The specific surface area of the samples reached up to 3733 m2·g−1, while the maximum specific capacitance of the samples obtained was up to 281.3 F·g−1 in the 3-electrode tests (1 A·g−1). The doping of N and S elements raised the specific capacitance significantly, which could be increased to a value as high as 422.5 F·g−1 at a current density of 1 A·g−1 in the 3-electrode tests, but N, S-codoping also led to instability. The results of this article prove that tobacco stalks could be efficiently reused in the field of supercapacitors.

Authors: Liu Wei , Lv Lutao , Yang Zonglin , Zheng Yuqing , Wang Hui
Published: August 2020

In this study, the filled natural rubber (NR) was prepared with organic montmorillonite (OMMT) and carbon black (CB). The effects of the amount of OMMT on the properties of CB/NR composites were investigated by measuring the physical and mechanical properties, compression set and compression heat properties, processing properties and damping properties. The formulation was optimized depending on the different conditions of end applications and the damping properties of rubber were maximized without affecting the other properties of the rubber. The results showed that the rubber composite system filled with 2 phr (parts per hundreds of rubber) OMMT had better mechanical properties and excellent damping performance.

Published: August 2020

Conducting graphene oxide/polydiphenylamine (GO/PDPA) microsheet nanocomposite particles were fabricated via in-situ oxidative polymerization using diphenylamine in the presence of GO. The morphological structures and dimensions of the fabricated GO/PDPA composites were evaluated using transmission electron microscopy and scanning electron microscopy. Electrorheological (ER) responses and creep behaviors of an ER fluid consisting of the GO/PDPA composites when suspended in silicone oil were evaluated using a rotational rheometer under input electric field. Three different types of yield stresses were examined along with dielectric analysis, demonstrating their actively tunable ER behaviors.

Published: August 2020

The analysis of chlorophyll concentration based on spectroscopy has great importance for monitoring the growth state and guiding the precision nitrogen management of potato crops in the field. A suitable data processing and modeling method could improve the stability and accuracy of chlorophyll analysis. To develop such a method, we collected the modelling data by conducting field experiments at the tillering, tuber-formation, tuber-bulking, and tuber-maturity stages in 2018. A chlorophyll analysis model was established using the partial least-square (PLS) algorithm based on original reflectance, standard normal variate reflectance, and wavelet features (WFs) under different decomposition scales (21–210, Scales 1–10), which were optimized by the competitive adaptive reweighted sampling (CARS) algorithm. The performances of various models were compared. The WFs under Scale 3 had the strongest correlation with chlorophyll concentration with a correlation coefficient of −0.82. In the model calibration process, the optimal model was the Scale3-CARS-PLS, which was established based on the sensitive WFs under Scale 3 selected by CARS, with the largest coefficient of determination of calibration set (Rc2) of 0.93 and the smallest Rc2−Rcv2 value of 0.14. In the model validation process, the Scale3-CARS-PLS model had the largest coefficient of determination of validation set (Rv2) of 0.85 and the smallest root–mean–square error of cross-validation (RMSEV) value of 2.77 mg/L, demonstrating good prediction capability of chlorophyll concentration. Finally, the analysis performance of the Scale3-CARS-PLS model was measured using the testing data collected in 2020; the R2 and RMSE values were 0.69 and 3.36 mg/L, showing excellent applicability. Therefore, the Scale3-CARS-PLS model could be used to analyze chlorophyll concentration. This study indicated the best decomposition scale of continuous wavelet transform and provided an important support method for chlorophyll analysis in the potato crops.

Published: August 2020

Short-Term Load Forecasting (STLF) is the most appropriate type of forecasting for both electricity consumers and generators. In this paper, STLF in a Microgrid (MG) is performed via the hybrid applications of machine learning. The proposed model is a modified Support Vector Regression (SVR) and Long Short-Term Memory (LSTM) called SVR-LSTM. In order to forecast the load, the proposed method is applied to the data related to a rural MG in Africa. Factors influencing the MG load, such as various household types and commercial entities, are selected as input variables and load profiles as target variables. Identifying the behavioral patterns of input variables as well as modeling their behavior in short-term periods of time are the major capabilities of the hybrid SVR-LSTM model. To present the efficiency of the suggested method, the conventional SVR and LSTM models are also applied to the used data. The results of the load forecasts by each network are evaluated using various statistical performance metrics. The obtained results show that the SVR-LSTM model with the highest correlation coefficient, i.e., 0.9901, is able to provide better results than SVR and LSTM, which have the values of 0.9770 and 0.9809, respectively. Finally, the results are compared with the results of other studies in this field, which continued to emphasize the superiority of the SVR-LSTM model.

Published: August 2020

Smart Cities empower progress through technology integration directed with a strategic approach to sustainable development and citizen well-being. The creation of solid strategic planning boosts the development of infrastructure, innovation, and technology. However, the above can be compromised if citizens are not properly involved; therefore, it is relevant to enhance citizen participation when a new Smart City project appears on the horizon. This work presents a Smart Cities Oriented Project Planning and Evaluation (SCOPPE) Methodology that combines the citizen participation and the Minimum Viable Product creation through adaptive project management. Moreover, since the smart mobility projects represent the first step towards a Smart City, a case of study of an Intelligent Parking System (SEI-UVM) is presented following the SCOPPE Methodology. The application’s steps results lead us to key and useful information when defining, designing, and implementing the minimum viable product of the cornerstone device of the SEI-UVM: the Smart Vehicle Presence Sensor (SPIN-V). It is worthwhile to mention that the proposed SCOPPE Methodology could be extended to any Smart City project.
Multiple Goals, Attention Allocation, and the Intention-Achievement Gap in Energy Efficiency Innovation
Authors: Kim Tohyun , Yang Daegyu
Published: August 2020

Although improving energy efficiency has many benefits, including not only reducing pollution and climate change but also enhancing productivity and competitiveness, many firms still do not adopt energy efficiency innovation. In this study, we suggest inadequate attention allocation as a barrier to energy efficiency innovation, making firms fall into the intention-achievement gap when they simultaneously pursue multiple innovation-related goals. Due to limits in attention resources, competing innovation goals are likely to divert the firms’ focus of attention away from energy efficiency innovation, making them fail to achieve as much as they had initially intended. In addition, we argue that organizational innovation and government dependence will mitigate the attention dispersion effect of multiple goals by enhancing attention capacity and redirecting attention focus, respectively. We empirically examined our hypotheses in the context of Korean manufacturing industries between 2011 and 2013, using the Korean Innovation Survey 2014 data, and found supports for all hypotheses. In particular, we found that even a small increase in the diversity of innovation goals leads to a substantial likelihood of the intention-achievement gap and that organizational innovation and government dependence help to close the gap, but to a limited extent. Finally, theoretical contributions and practical implications are discussed.
Effects of Human Behavior Simulation on Usability Factors of Social Sustainability in Architectural Design Education
Authors: Hong Seung Wan , Kim Hwanjin , Song Yongjun , Yoon Sung Hoon , Lee Jaewook
Published: August 2020

While the social sustainability of built environments is an essential aspect of architectural design education, systemic experiments still lack empirical pedagogy. Therefore, factors of social sustainability are hardly reflected in students’ projects seamlessly. To overcome such limitations, this study investigates the applicability and effectiveness of human behavior simulation. To ensure authentic architectural design, the projects were equipped with autonomous, rational anthropomorphic computer agents called virtual users (VUsers). This study compared the performance scores on social sustainability factors, assessed by the students who conducted design projects both before (without) and after (with) using the simulation. A one-way analysis of variance indicated that human behavior simulation promoted the performance of projects with respect to the parameters of accessibility and safety, ergonomic usability for heterogeneous users and supportability of social interactions. However, the simulation was not found to be effective in promoting the physical attractiveness of built environments and in ensuring the completeness of design solutions. Based on previous studies, the present study interpreted the reasons why the operability of VUsers and built environments, representations of emerging interactions of VUsers and whole-and-part analytics promoted explicit experimentation, but the factors of physical attractiveness and completeness were irrelevant to the rational examinations in the use of the simulation.
Human Resource Management for Ghanaian Nurses: Job Satisfaction Versus Turnover Intentions
Authors: Coudounaris Dafnis N. , Akuffo Isaac Nana , Nkulenu Annie Owusua
Published: August 2020

The study has the aim of exploring the determinants of turnover intentions and job satisfaction of nurses. A survey of 163 nurses from two public and two private hospitals in the capital of Ghana, Accra, who completed a questionnaire in English, was conducted. The study uses SEM analysis to evaluate the goodness-of-fit of the model and to test hypotheses. Regarding the findings, pay rise, pay structure/administration and job satisfaction were significantly and negatively related to turnover intentions. However, the effect of benefits on turnover intentions was nonsignificant and was negatively associated with turnover intentions. The antecedents of nurses’ job satisfaction, all the constructs, i.e., pay level, pay rise, benefits, and pay structure/administration, had positive and statistically significant impacts. The influence of pay level, pay structure/administration and pay rise had the most important effect on nurses’ job satisfaction. In addition, the age status as a control variable had negative and significant effects on turnover intentions. However, gender status as a control effect had a nonsignificant impact on turnover intentions. It is recommended that the government of Ghana, the Ministry of Health, and the Ghana Health Service must institute measures such as the provision of competitive salaries and a quality work environment to entice nurses to stay in order to reduce the exodus of nurses outside the shores of Ghana. One limitation of this study is that there are other factors that could cause employees to quit their jobs, such as employee commitment, engagement, and leadership behaviours but these variables were not tested. Therefore, future studies must control these variables in studies regarding pay satisfaction and turnover intentions.

Authors: Nadanyiova Margareta , Gajanova Lubica , Majerova Jana
Published: August 2020

Green marketing is focused on a responsible approach to the environment, which is integrated into various areas of society. In order to build a successful and socially responsible brand, it strives to apply environmental principles that attract new customers or strengthen the loyalty of existing ones. To ensure success, it is necessary to focus on green marketing as a part of socially responsible brands’ communication to individual target groups, which can be divided according to the age of the consumer generations, which have similar requirements for product characteristics. The main aim of the paper is to determine the differences between generational cohorts of Slovak consumers in perception of green marketing as part of socially responsible brands’ communication. The most important sources for secondary data were scientific research, statistical databases, and published professional publications. In order to find out the perception of green marketing as a part of socially responsible brands’ communication from the aspect of generational stratification, a questionnaire survey was conducted among Slovak consumers. Based on the analysis and results of the questionnaire survey, benefits of green marketing as part of socially responsible brands’ communication focused on individual consumers’ generations are highlighted, such as gaining competitive advantage, increasing the brand value, improving brand loyalty, and increasing the attractiveness for investors.
A 1% Measurement of the Gravitomagnetic Field of the Earth with Laser-Tracked Satellites
Authors: Lucchesi David , Visco Massimo , Peron Roberto , Bassan Massimo , Pucacco Giuseppe , Pardini Carmen , Anselmo Luciano , Magnafico Carmelo
Published: August 2020

A new measurement of the gravitomagnetic field of the Earth is presented. The measurement has been obtained through the careful evaluation of the Lense-Thirring (LT) precession on the combined orbits of three passive geodetic satellites, LAGEOS, LAGEOS II, and LARES, tracked by the Satellite Laser Ranging (SLR) technique. This general relativity precession, also known as frame-dragging, is a manifestation of spacetime curvature generated by mass-currents, a peculiarity of Einstein’s theory of gravitation. The measurement stands out, compared to previous measurements in the same context, for its precision (≃7.4×10−3, at a 95% confidence level) and accuracy (≃16×10−3), i.e., for a reliable and robust evaluation of the systematic sources of error due to both gravitational and non-gravitational perturbations. To achieve this measurement, we have largely exploited the results of the GRACE (Gravity Recovery And Climate Experiment) mission in order to significantly improve the description of the Earth’s gravitational field, also modeling its dependence on time. In this way, we strongly reduced the systematic errors due to the uncertainty in the knowledge of the Earth even zonal harmonics and, at the same time, avoided a possible bias of the final result and, consequently, of the precision of the measurement, linked to a non-reliable handling of the unmodeled and mismodeled periodic effects.

Immunosuppression is a risk factor of persistent human papillomavirus (HPV) infections, which might lead to development of (pre)malignant lesions of the cervix and lower anogenital tract. Results of HPV DNA testing using cervicovaginal self-samples are comparable to those that are clinician-obtained and therefore might be used in cervical screening. The aim of this study was to assess the prevalence of high-risk HPV (hrHPV) infections, their risk factors and the genotypes distribution among women undergoing immunosuppressive therapy. Women undergoing immunosuppressive therapy for at least three months due to solid organ transplantation or autoimmune disorders were asked to self-collect samples for HPV testing using cervicovaginal brushes and complete questionnaires regarding cervical cancer risk factors. HPV DNA detection and genotyping were performed using Genotyping kit HPV GP version 2. hrHPV was detected in 26/90 (28.9%) specimens. Genotyping revealed a broad range of hrHPV, with type 16 being the most common genotype (11/26). The components of bivalent/quadrivalent or nonavalent vaccines cover all genotypes present in 4.4% and 17.8% women, respectively, and occur as a co-infection with other types in 12.2% and 23.3% of women, respectively. The only feature significantly associated with being hrHPV-positive was having at least two lifetime sexual partners. The high prevalence of hrHPV infections among immunosuppressed women emphasizes the need for regular cervical cancer screening with HPV DNA testing, which might be performed on self-collected specimen.

Bluetongue (BT) is an arthropod-borne viral disease of ruminants with serious trade and socio-economic implications. Although the disease has been reported in a number of countries in sub-Saharan Africa, there is currently no information on circulating serotypes and disease distribution in Zambia. Following surveillance for BT in domestic and wild ruminants in Zambia, BT virus (BTV) nucleic acid and antibodies were detected in eight of the 10 provinces of the country. About 40% (87/215) of pooled blood samples from cattle and goats were positive for BTV nucleic acid, while one hartebeest pool (1/43) was positive among wildlife samples. Sequence analysis of segment 2 revealed presence of serotypes 3, 5, 7, 12 and 15, with five nucleotypes (B, E, F, G and J) being identified. Segment 10 phylogeny showed Zambian BTV sequences clustering with Western topotype strains from South Africa, intimating likely transboundary spread of BTV in Southern Africa. Interestingly, two Zambian viruses and one isolate from Israel formed a novel clade, which we designated as Western topotype 4. The high seroprevalence (96.2%) in cattle from Lusaka and Central provinces and co-circulation of multiple serotypes showed that BT is widespread, underscoring the need for prevention and control strategies.
A Health Indicator for the Online Lifetime Estimation of an Electric Vehicle Power Li-Ion Battery

Published: August 2020

With the further development of the electric vehicle (EV) industry, the reliability of prediction and health management (PHM) systems has received great attention. The original Li-ion battery life prediction technology developed by offline training data can no longer meet the needs of use under complex working conditions. The existing methods pay insufficient attention to the dispersive information of health indicators (HIs) under EV driving conditions, and can only calculate through standard configuration files. To solve the problem that it is difficult to directly measure the capacity loss in real time, this paper proposes a battery HI called excitation response level (ERL) to describe the voltage variation at different lifetimes, which could be easily calculated according to the current and voltage under the actual load curve. In addition, in order to further optimize the proposed HI, Box–Cox transformation was used to enhance the linear correlation between the initially extracted HI and the capacity. Several Li-ion batteries were discharged to the 50% state of health (SOH) through profiles with different depths of discharge (DODs) and mean states of charge (SOCs) to verify the accuracy and robustness of the proposed method. The average estimation error of the tested batteries was less than 3%, which shows a good performance for accuracy and robustness.

Published: August 2020

The article discusses the reserves that the institution generates. The new standards on reserves are analyzed, for whom they are intended and what reserves are needed in what cases. It is shown that all reserves are divided into those that must be formed necessarily and those that are created when necessary. The General algorithm of actions for creating a reserve for vacation payment and checking reserves for the past year, as well as the situation when the vacation and the reserve did not coincide, is considered. Examples of calculations and accounting for vacation pay that the reserve does not fully cover and calculation of the reserve per employee are given. A new reserve for cost reduction is considered. It is created if the institution produces products intended for sale. It is shown that the reserve for claims and claims is formed if, as of the reporting date, the institution has already submitted claims or is involved in legal proceedings. The author analyzes the creation of a restructuring reserve, which is necessary if an institution restructures its activities or is liquidated. It is shown that the formation of a reserve for warranty repairs is carried out in cases where the institution has a production facility and the corresponding conditions in contracts with customers. A provision for unprofitable contractual obligations is formed if you cannot terminate the agreement unilaterally. The accounting of reserves is considered. Contingent liabilities and their differences from reserves are analyzed.

The article assesses the changes made by the Order of the Ministry of Finance of the Russian Federation dated 20.11.2018 No. 236n v PBU 18/02 “Accounting for settlements with the budget for income tax”. The application of the new norms of PBU 18/02 is mandatory for corporate income tax payers with accounting (financial) statements for 2020. The essence of the problem is that the updated PBU 18/02 contains new concepts, new calculations of indicators necessary for reflection in accounting and accounting (financial) statements. The article consists of six parts, beginning with an introduction and ending with conclusions. The introduction substantiates the relevance of the study. At the beginning of the article, the purpose and objectives of the research are defined, as well as the materials, methods and conditions for conducting the research. The results of the study and their discussion are presented below. In the article, the authors highlight the problem of transition from the previously existing norms of PBU 18/02 to the new norms applied from 2020. The main part compares the concepts and indicators used in 2019 and 2020 in accordance with the requirements of PBU 18/02. The article also addresses the issues of evaluating work in progress in accordance with the requirements of regulatory legal acts in the field of accounting and taxation. The procedure for applying the norms of PBU 18/02 is shown on a specific example and the calculation procedures made that justify the occurrence of temporary differences that lead to the recognition of deferred income tax, as well as conditional income tax expense and current income tax on the accounting accounts. For clarity and comparison, the indicators for the application of PBU 18/02 in 2019 and 2020 are presented in the tables. In addition, the tables show the schemes of accounting transactions for accounting calculations with the budget for income tax in two ways to determine the current income tax: based on accounting data and based on tax Declaration data. Having considered a specific example of the procedure for applying the norms of PBU 18/02 in the version up to 2020 and in the current version from 2020, the authors conclude that changes in the procedure for identifying temporary differences do not mean a change in their value and the value of net profit

El área concreta de estudio corresponde a La Balanza, un barrio pobre situado en los cerros, en la “parte alta”, la de menor nivel socioeconómico y estatus del distrito.La investigación está basada en un trabajo de campo realizado entre los años 2010 y 2012. Para su desarrollo fueron claves la observación participante y las entrevistas en profundidad efectuadas a 26 jóvenes —13 mujeres y 13 hombres— de entre 18 y 30 años de edad, y a 6 adultos —2 mujeres y 4 hombres— de entre 36 y 51 años. Estos adultos, habituados a relacionarse con jóvenes, se seleccionaron como Informantes complementarios, con el fin de contar con más puntos de vista que fortalecieran los datos obtenidos a través de los jóvenes.El cortejo necesita un proceso previo de selección, un primer encuentro, que suele ocurrir en cualquier espacio de Comas. Se distinguen lugares estratégicos y lugares inesperados para el cortejo. Los amigos1 facilitan el proceso del cortejo por medio de presentaciones y proporcionando cierta seguridad en un contexto considerado inseguro. Uno de los cortejos es el meramente sexual, que se asume con normalidad, pero se silencia. Para el cortejo sexual hay lugares específicos como las discotecas, que propician vacilones o encuentros sexuales esporádicos. La práctica del sexo es muy frecuente y se da en casi todos los espacios de Comas, tanto privados (casas, hoteles u hostales, video cabinas, mototaxis) como públicos, teniendo siempre cuidado de no ser vistos. Hay toda una economía para el sexo en la que se diferencian distintos espacios de mayor o menor nivel según el coste.
Forjando la espiritualidad cristiana
Authors: Puertas Porras María Elizabeth
Published: August 2020

El presente artículo busca describir las características del discurso evangelizador con respecto a la explicación de la Fe y la naturaleza de Dios en el Sermonario del extirpador de idolatrías Fernando de Avendaño. Los sermones publicados en 1649 están orientados, desde nuestra perspectiva, a consolidar la conciencia espiritual cristiana entre la población originaria de la Lima virreinal que aún mantenía creencias religiosas tradicionales. Buscamos evidenciar cómo una prédica que apela a la razón, desde la observación de la realidad, lleva a los oyentes a reflexionar y eventualmente interiorizar conceptos fundamentales del cristianismo.
El pretérito perfecto compuesto en relatos del castellano de Acolla (Junín)
Authors: García Rojas Yrma Doris
Published: August 2020

Este artículo científico da cuenta del comportamiento morfosintáctico del pretérito perfecto compuesto (PPC) en relación con el pretérito perfecto simple (PPS) en el castellano de Acolla. El objetivo del estudio fue determinar si la frecuencia de uso del PPC era mayor al de PPS en relatos orales del pasado de esta variedad dialectal. Se trabajó sobre la base de la producción narrativa de 75 niños y niñas de seis años, monolingües del castellano. La estrategia Mi mascota favorita (MMF) resultó ser bastante efectiva para el acopio de información, insumo útil en la conformación del corpus lingüístico. Para el cálculo de la frecuencia absoluta y relativa de las formas verbales involucradas, se utilizó el programa informático Windows AntConc, versión 3.2.4. Los resultados señalan que en el castellano de Acolla, la frecuencia de uso del PPC es significativamente mayor a la del PPS tal como ocurre en otras variedades de castellano andino. Se concluye que en el castellano de Acolla, el PPC goza de mayor preferencia en narraciones que describen eventos temporalmente ocurridos no solamente en un pasado lejano sino también remoto.
Konsepsi Siswa dalam Proses Pemodelan Matematis
Authors: Zulkarnaen Rafiq
Published: August 2020

Tujuan penelitian ini untuk mengkaji konsepsi siswa dalam proses pemodelan matematis. Desain studi kasus tunggal dan analisis tunggal dengan sampling-teoritis digunakan dalam penelitian ini. Dua siswa (S-17 dan S-23) dipilih dari 35 siswa kelas X pada satu SMAN di Kabupaten Karawang. Kedua siswa diminta untuk menyelesaikan situasi masalah dunia nyata. Hasil penelitian menunjukkan bahwa konsepsi siswa terhadap suatu konsep matematika digunakan dalam menyelesaikan masalah akan tetapi konsepsi tersebut belum menuntun siswa kepada solusi yang tepat. Idealnya, dalam proses pemodelan matematis konsepsi yang dilakukan oleh siswa tidak hanya sebatas pemaknaan atau interpretasi konsep atau prosedur matematika, tetapi juga dalam pemodelan matematis konsepsi digunakan dalam interpretasi situasi masalah dunia nyata.
Physicochemical and mechanical properties of selected cohesive soils of Lublin region used in waterproofing applications
Authors: Gazda Lucjan , Franus Małgorzata
Published: August 2020

In this paper preliminary characteristics of selected cohesive soils of Lublin region that can be used in waterproofing applications in geotechnics and constructions is presented. The investigations and analysis were made according to the applicability criteria of materials used as mineral waterproofing barriers which have been elaborated in the last years in Institute of Building Techniques. On the basis of petrographical, mineral, filtering, structural and mechanical properties, the usability of slits from Bychawa and Łążek Ordynacki and powdery clay from Markowicze was confirmed, whereas glauconitic clay from Gawłówka did not meet all the criteria. The study has shown that a great number of parameters that determine the usability criteria, are resulting from petrography and mineralogy of the soils. A perfect suitable soil for that purpose has not been found, but a complementation of parameters in particular types of soils has been detected. This result gives a possibility to obtain composite materials (multilayered and homogenized).
Experimental buckling path of compressed bars under displacement control
Authors: Imiełowski Szymon , Glinicka Aniela , Ajdukiewicz Cezary
Published: August 2020

Buckling and postcritical analysis of prismatic metal bars, including complex cycles of loading are considered in the paper. The postbuckling path analysis of bars loaded in the form of increasing displacements is discussed in detail. The results of experimental research are reported as a dependence of the force P versus lateral deflection f as well as total shortening of the rod u. It is stated that only the simultaneous analysis of both methods of presentation of results comprises a complete tool for developing the column response. Particularly, the response that appears in the first, linear elastic phase of loading can be observed on P-u diagrams. The increase of the compressing force causes visible shortening of the bar without its buckling. This important phenomenon is not usually included in stability considerations of prismatic rods.

Authors: Kulpa Maciej , Siwowski Tomasz
Published: August 2020

The growing need of durability enhancement for road bridge decks has recently caused the big impulse for research on new, durable, lightweight and easy to handle bridge decks, made of advanced materials, f.e. FRP (fibre reinforced polymers). The initial results of research on the first Polish FRP bridge deck have been presented in the paper. In the frame of UE 7FP the three structural solutions of sandwich FRP bridge deck have been elaborated, produced and tested under static load. On the basis of test results the stiffness and carrying capacity of panels have been estimated and the best solution for further research has been chosen.
Ultrasonic modulated waves for diagnostics of concrete elements in bending
Authors: Meronk Błażej , Wilde Krzysztof
Published: August 2020

The paper presents the experimental study on the diagnostics of concrete elements with the use of nonlinear acoustic effects. The tests were conducted on a concrete plate subjected to ultrasonic waves modulated with and without an additional low frequency actuator. The experimental results showed that the new method based on the direct modulation of diagnostic ultrasonic waves also provided sub-harmonic frequencies that indicated the presence of damage. The new method does not require a low frequency actuator for generation of low frequency oscillations, and therefore, is more suitable for practical application.

Authors: Szulej Jacek , Pieńko Michał , Franus Wojciech
Published: August 2020

The purpose of this article is to present the results of the first stage of research on the damping parameters of vibration and the material characteristics of reinforced concrete structures with the addition of zeolite tuffs. The first part of the article describes the properties of zeolites as well as its impact on the concrete parameters. The main part of the article shows the partial results of research on damping parameters of vibration of reinforced concrete slab models. The models contain modified binder in which the portion of cement was replaced by zeolite (tested models and samples contained 0%, 10%, 20%, 30%, 40% of zeolite). The values of damping coefficients of vibration were determined by the collocation method, and only the first frequency of free vibration of models was taken into account. Moreover, the material characteristics of modified concrete were determined, ie compressive strength (after 3, 7, 14, 28, 56, and 90 days), frost resistance, water absorption, friability, as well as the values of Young modulus.
Risk aided design of building structures
Authors: Woliński Szczepan
Published: August 2020

The potential failure of building structures usually arises from a combination of many unspecified causes or catastrophic events whose statistical description is highly uncertain and often impossible. Assumed or calculated reliability of the structure in a case is just a notional measure that can be used to compare the relative safety level of different structures in similar circumstances. Due to the difficulties associated with the estimation of the probability of different hazards as well as the assessment of consequences and costs of the structural damage and failure, also the risk analysis provides very uncertain information on the actual level of safety of a structure. The paper presents a proposal for an indirect approach to the probabilistic design of structures based not only on specific actions, but also on the ability of the structure to survive in the unique , unusual and vaguely defined circumstances. It requires a preliminary risk analysis before the standard procedures for shaping and dimensioning design elements will be applied.
Roads and water: interactions considered on different levels of planning and designing
Authors: Dąbal Agata
Published: August 2020

The main subject of this paper is the relationship between roads and one of the environmental components: water. This element was chosen due to its common occurrence and the necessity for all the organisms. Additionally because of its destroying force. Analyses were conducted on different levels of planning and designing, from strategic documents to individual cases. The study showed that stra­tegic documents prepared for water management are really important for designing, construction and exploitation of roads. Nowadays, a modern attitude towards designing elements which can have an impact on the water bodies is necessary. This approach needs to take into consideration environmental objectives stated for water bodies in order to reduce pressure, not only implied by sewage precipitation water which changes river water quantity and quality, but also has an impact on the river bed which can influence hydrodynamic balance. This modern attitude should encompass the issue of preservation river bed characteristic status as described by typical water bodies reference conditions.
