Authors: Kaźmierska-Zatoń Maria , Zatoń Wojciech 
Published: August 2020

Abstract

Research background: Surveys of entrepreneurs regarding the assessment of conditions for conducting business activity are carried out by several institutions. They focus on business climate indicators but in parallel they report on numerous barriers to economic activity. The paper examines the barriers that hinder business operations to manufacturing enterprises in Poland.

Purpose: The purpose of the paper is to analyse the barriers to business activity and their role in entrepreneurs’ assessment of their general economic situation. It has been hypothesized that statistically significant barriers to economic activity that affect the assessment of the general economic situation by entrepreneurs can be determined.

Research methodology: The analysis was based on the Central Statistical Office data from the business tendency survey in manufacturing enterprises spanning the period 2003–2019, broken down into groups of small, medium-sized and large enterprises. Correlation measures and regression models were used.

Results: The results allow indicating several barriers that have a significant impact on the assessment of the current economic situation by entrepreneurs. This impact varies depending on the size of the enterprise. No significant relationship was found between the barriers and the assessment of the expected economic situation.

Novelty: The paper contributes to studies on business tendency surveys. It develops a detailed analysis of the barriers to economic activity, takes into account the size of enterprises and examines the influence of business barriers on the assessment of the economic situation by entrepreneurs.
A modification of predictive three-component model for turbulent flows of complex slurries in pipelines based on experimental results
Authors: Kesely Mikolas 
Published: August 2020

Abstract
The paper describes a mathematical and physical modelling of flow of complex slurries in pipelines, i.e. a flow of slurries composed of solids covering a very broad range of particle sizes that overlaps more than one flow patterns – non-Newtonian, pseudohomogeneous, heterogeneous and fully-stratified. A typical examples are residual products (“tailings”) from mining industry with normal average particle sizes of 20 to 100 μm or more. Experimental results of flows of complex slurries composing of non-Newtonian carrier fluid and three fractions of glass particles in 50 mm pipe are presented. Depending on the particle size, particles show different flow patterns and therefore considerable differences in pressure drops. Fine particles tend behave as a homogeneous matter, while coarser particles exhibit heterogeneous behaviour and even coarser particles form a sliding bed. A mathematical 3-component predictive model for turbulent flow of complex slurries is presented based on well-established semi-empirical formulae developed originally for flows with Newtonian carrier. The predicted values of pressure drops show very reasonable agreement with experimental results and indicate suitability of the model for engineering practice.
Opportunity Inequality in Accessing Higher Education and Presentation of Equity Promotion Model to Achieve Sustainable Development: A Case Study of West Azerbaijan Province in Iran
Authors: Hassani Mohammad , Najjari Mahdi 
Published: August 2020

Abstract
This study was aimed to investigate the inequality of opportunity of access to the higher education centers and to present a model of reducing inequality of opportunities and to administer justice and fairness in order to achieve a sustainable development among the 17 cities and towns of West Azerbaijan Province, Iran. This research was a descriptive-analytic and survey type of study in nature. The participants included 890 pre-university high school students who completed a set of questionnaires eliciting their perceptions on opportunity inequality in accessing higher education. Moreover, documents adopted from the responsible governmental bodies on this topic were analyzed. The collected data were analyzed using Pearson correlation coefficient, cluster analysis, path analysis and neural networks by means of Topsis, SPSS, and Excel softwares. The findings showed that there is inequality of opportunity of access to the higher education centers in cities of West Azerbaijan. Based on the path analysis, admission and individual-family indexes had the most and the least impacts on inequality of achieving higher education, respectively, among the cities of West Azerbaijan. Moreover, the neural networks model showed that the education indexes were the most important and the individual-family indexes were the least important ones in predicting the opportunity of accessing higher education in these cities. This study reveals that a three-componential model (namely, education, admission, and family-individual) along with their sub-components could be the basis for achieving education for sustainable development.
Urban agriculture in Havana – evidence from empirical research
Authors: Górna Ada , Górny Krzysztof 
Published: August 2020

Abstract
The aim of this article is to indicate the features of contemporary urban agriculture present in the contiguously built-up areas of Havana. Using an exploratory and classification approach, the authors draw on fieldwork and a prior analysis of satellite and aerial imagery, first to characterize the spatial distribution of urban gardens and then to point to their main intrinsic features, including the methods and organization of production and the functions performed. The research conducted shows that urban agriculture is distributed across the city in an uneven fashion, with the main concentration in districts of lower-density urban construction, which reflects the availability of land resources intentionally left between buildings by modernist planners. The most common production technique applied is organopónico, or organoponics. However, the material commonly used to construct the bordering walls is asbestos, which may pose a significant threat for both producers and consumers. Two case studies are analyzed to exemplify different approaches to organic food production.

Semi-structured interviews were conducted to 10 nurses from different hospitals in West Java and South Sumatra provinces. The snowball sampling technique was used to recruit participants. Data from the interviews were analyzed using the Comparative Analysis for Interview technique to find the study themes. Results, three themes emerged from the data analysis including the concept of halal healthcare tourisms is applied in health services, barriers in developing halal healthcare tourism, and the leader determines the main focus of services programs in the hospital. In conclusion, these findings provide an understanding of the potency of Indonesian hospitals in the halal healthcare tourism market from nurses’ perspectives, yet several barriers were also identified. A comprehensive assessment is needed to obtain other health professionals’ opinions, and to raise their awareness of the strength of this industry in Indonesia.
X-ray diffraction study of the elastic properties of jagged spherical CdS nanocrystals
Authors: Dey Pijush Ch. , Sarkar Sumit , Das Ratan 
Published: August 2020

Abstract
In this work, jagged spherical CdS nanocrystals have been synthesized by chemical method to study their elastic properties. The synthesized CdS nanocrystal has been characterized by transmission electron microscopy (TEM) and X-ray diffraction (XRD). The transmission electron microscope images show that the average size of the nanocrystal is 100 nm approximately. X-ray diffraction (XRD) study confirms that the CdS nanocrystals are in cubic zinc blende structure. The size calculated from the XRD is consistent with the average size obtained from the TEM analysis. The XRD data have been analyzed to study the elastic properties of the jagged spherical CdS nanocrystals, such as intrinsic strain, stress and energy density, using WilliamsonHall plot method. Williamson-Hall method and size-strain plot (SSP) have been used to study the individual effect of crystalline size and lattice strain on the peak broadening of the jagged spherical CdS nanocrystals. Size-strain plot (SSP) and root mean square (RMS) strain further confirm the results obtained from W-H plots.

Published: August 2020

Abstract
In this work was established that serial traditional hardfacing materials based on the Fe-Cr-C system are not effective for improvement of abrasion resistance of elements of equipment for production of bricks, solid fuel briquettes and for restoration of augers, due to the fact that this equipment works at significant specific and cyclic loads. Features of the coarse-grained structure of Fe-Cr-C based coatings leads to intensive abrasive wear. The aim of this study was to increase a durability of that equipment by using of flux cored electrodes with reaction components of Ti, Cr, Mo, B4C and their combinations to provide synthesis, which leads to fine-grained structure of refractory borides and carbides and their solid solutions with increased hardness. Structure of the hardfacing coatings were investigated by method of metallography, scanning electron microscopy (SEM), electron backscatter diffraction (BSD) mode and energy dispersive X-ray spectroscopy (EDS). Temperature dependences of equilibrium phase amount of the hardfacing materials were calculated by the CALPHAD technique, using JMatPro software. It was investigated that the offered materials are characterized by higher wear resistance at high specific and cyclic loads in comparison with serial production high-chromium hardfacing materials (Lastek, ESAB, Paton IEW). It was established that the abrasion wear resistance at high specific and cyclic loads depends mostly of formation of the structure of hardfacing material, and not the hardness. Also, using of powders of pure metals and their combination as reaction mixture for FCAW leads to fine structure which contains of refractory borides and carbides and their solid solutions.

Abstract
This article addresses the method of sensing mechanical quantities, in particular force and pressure, without the electrical connection of the sensing element and the electronics. The information about the mechanical quantity is transmitted only by evaluating the changes in the electromagnetic field created around the sensor. The sensor is designed on the basis of a flexible micro-electro-mechanical element (MEMS), the resonance of which carries the information about the measured quantity.
How private is your period?: A systematic analysis of menstrual app privacy policies
Authors: Shipp Laura , Blasco Jorge 
Published: August 2020

Abstract
Menstruapps are mobile applications that can track a user’s reproductive cycle, sex life and health in order to provide them with algorithmically derived insights into their body. These apps are now hugely popular, with the most favoured boasting over 100 million downloads. In this study, we investigate the privacy practices of a set of 30 Android menstruapps, a set which accounts for nearly 200 million downloads.We measured how the apps present information and behave on a number of privacy related topics, such as the complexity of the language used, the information collected by them, the involvement of third parties and how they describe user rights. Our results show that while common pieces of personal data such as name, email, etc. are treated appropriately by most applications, reproductive-related data is not covered by the privacy policies and in most cases, completely disregarded, even when it is required for the apps to work. We have informed app developers of our findings and have tried to engage them in dialogue around improving their privacy practices.
Correlations between intra and extraarticular factors measured by computed tomography in patients with recurrent patellar dislocation
Authors: Iacobescu Georgian , Cursaru Adrian , Anghelescu Dan , Popa Mihnea , Popescu Dan 
Published: August 2020

Abstract
Introduction: Lateral patellar dislocation (LPD) is a common injury of the knee, most frequent in young patients. It has a multifactorial etiology with several underlying risk factors. In most cases, patellar dislocation occurs on the lateral side, with the rupture of the medial patellofemoral ligament (MPFL), appearing in more than 80% of the cases. The tibial tuberosity-trochlear groove (TT-TG) distance of 20 mm or more in patients with lateral patellar dislocation is a gold standard for the surgical indication of tibial tubercle osteotomy (TTO).
Hypothesis: Our investigation aimed to establish whether there is a correlation between the TT-TG distance and other bony landmarks, like trochlear groove medialization, tibial tuberosity lateralization, and knee rotation angle, in the surgical algorithm for the patient with patellar dislocation.
Methods: We conducted a prospective study, analyzing and comparing data from two groups, 33 patients with a diagnosis of patellar dislocation, and a control group of 30 patients, with meniscal injury, but healthy contralateral limb. Using computed tomography, we measured the TT-TG distance, femoral anteversion, tibial torsion, knee rotation angle, tuberosity lateralization, and trochlear groove medialization of all the patients in our study. The measurements were conducted by two independent orthopedic surgeons in a randomized manner. Using an unpaired t test, we compared and analyzed each parameters value from the study and the control group.
Results: Comparing the two groups, we observed a significant difference for TT-TG distance, knee rotation angle and tibial tuberosity lateralization with higher values in the study group compared to the control group (CI 95% 6.44-9.72, CI 95% 8.64-10.39, CI 95% 3.77-5.46, respectively), with a p value < 0.0001 in all cases. Also, the TT-TG distance positively correlated with knee rotation angle (r=.97, p=0.01) and tibial tuberosity lateralization (r=.86, p=0.0001) in the study group.
Conclusions: The TT-TG distance measurement usually defines the lateralization of the tibial tuberosity; yet, in some cases, it can be caused by the trochlear groove medialization, or high rotation between the femur and tibia. Our study revealed that knee rotation and tuberosity lateralization were factors implicated in patellar dislocation and they should be taken into account when making the decision of tibial tubercle osteotomy.

FACTORS OF FORMATION OF DEMAND FOR EDUCATIONAL SERVICES OF HIGHER EDUCATION
Authors: Rogova Vera 
Published: August 2020

Higher education is one of the Central subsystems of the social segment of the country, which provides individuals with ways to obtain comprehensive theoretical and practical knowledge and skills for their effective implementation in a professional manner and to meet the many needs of the individual, the population and the state.
In the course of consumption, educational services are transformed into a labor force, whose quality indicators depend on both the unity of the provided educational services, and on the quantitative and qualitative criteria of personal labor that were spent during the process of receiving such services, the individual's abilities, and the level of their implementation.
