Abstract

Introduction:
This study aims to investigate the relationship between prospective teachers’ self-management and self-control skills, metacognition, and e-mobile learning readiness perceptions.

Methods:
This study adopted a procedural model that was relational screening in nature. This study was conducted with 303 prospective teachers who attended Primary School Classroom Teaching, Primary School Science Teaching, Pre-school Teaching, and Psychological Counseling and Guidance departments in a State University Education Faculty in Turkey. In this study the “Self-control and self-management scale”, the “Metacognition scale” and the “E-Mobile learning readiness scale” were used as data collection tools. It was determined that the data collection tools used in the study were valid and reliable.

Results:
According to the results of the study, mobile learning readiness perception is positively affected by metacognition. Metacognition is positively affected by Self-management and Self-control Skills. In the study, the effects of e-mobile learning readiness perceptions on both metacognition and self-management and self-control skills were discussed in accordance with the proposed model.

Discussion:
The aim of this study is to determine the relationships between the variables of prospective teachers’ self-management and self-control skills, metacognition and e-mobile learning readiness perceptions. Four hypotheses in the proposed model were discussed according to the literature.

Limitations:
This study was conducted only with the participants consisting of teacher candidates at a state university in Turkey. However, the participants of the research can be expanded with different teaching areas of higher education.

Conclusions:
Prospective teachers’ self-regulation, self-assessment and control skills positively affect their metacognition skills. The metacognition skill of prospective teachers has a positive effect on mobile learning readiness perception.
Biotransformation of Hops-Derived Compounds in Beer – A Review
Authors: Klimczak Krystian , Cioch-Skoneczny Monika 
Published: July 2022

Abstract
Besides providing bitterness to beer, hops also impart a whole range of aromas, such as herbal, spice, floral, citrus, fruity and pine to this beverage. Although hops are usually added in relatively small amounts, they have a significant impact on the sensory characteristics of the product. Raw hop aroma significantly differs from the aroma resulting from its addition to the beer. The final aroma of the beer arises from substances in the malt, hops, other additives, and yeast metabolism. The biochemical transformation of hop compounds by yeast has become more and more popular in recent years. Knowledge of this process may allow more precise control over the final sensory characteristics of the beverage. The article describes the chemical composition of hops and discusses the influence of the hopping regime on the concentration of volatile compounds in the finished product. Moreover, the article describes the biotransformation of hop-derived compounds by traditionally used Saccharomyces cerevisiae yeast, as well as less commonly used non-Saccharomyces yeast. The paper outlines the current state of knowledge on biotransformation of hop-derived hydrocarbons, terpenoids, esters, sulfur compounds and glycosidically bound aroma precursors.

Abstract
Functional meat products are necessary to improve the health of consumers without detrimental effects on high biological value protein consumption. The incorporation of natural antioxidants and dietary fibre from agro-industrial coproducts is a good alternative to improve the nutritional characteristics of meat products. Pomegranate peel flour was employed as a functional ingredient to replace part of the fat, in a raw meat product like chorizo, determining changes in instrumental colour and texture, sensory acceptation, and neophobia. Pomegranate peel flour presented high content of polyphenols with considerable antioxidant activity, and high content of dietary fibre as well. Fibre retained moisture, decreasing water activity of the chorizos, decreasing pH during storage. Pomegranate peel flour increased the colour tone of the chorizos and decreased colour intensity, with a tough but easy to crumble texture. Sensory acceptation of chorizos with pomegranate peel flour was higher than control, although taste and texture were scored lower than the control sample. Results show that incorporation of pomegranate peel flour decreased Aw and pH, besides increased the samples luminosity and tone. Chorizo with pomegranate peel flour were harder than control. Nonetheless, as a functional ingredient improved health benefits with a positive consumers’ acceptance, non-neophobic, particularly in older consumers (40-50 years old). Pomegranate peel flour is a viable ingredient in the formulation of functional meat products.

Abstract
The leaves and unripe fruits from 5 walnut clones were tested in terms of mineral composition, antioxidant activity, and the inhibitory effect on model urease. It has been shown that the leaves are richer in minerals and also have higher antioxidant potential than unripe fruits. HPTLC polyphenolic profiles of leaves extract were found more abundant in flavonoids regardless of the sample origin. Only green walnut extracts showed an effect as urease inhibitors. Higher antibacterial activity was observed against Staphylococcus aureus in comparison with Staphylococcus epidermidis. Both leaf and fruit extracts showed antibiofilm activity, up to 95% of biofilm inhibition. It was shown that all tested Juglans regia extracts can serve as a valuable antibacterial agent against staphylococci infections.

Published: July 2022

Abstract
This work aimed to study the effect of convection drying on bioactive substances and on the texture profile of red pepper. Four mathematical models were used to model the drying kinetics, as a function of the temperature and the thickness of slices. These models are largely in agreement with experimental data. Effective diffusivity, Arrhenius constant, activation energy and thermal properties changed with temperature of dry process. The two varieties of pepper used in this work demonstrated a very high degree of spiciness (144799.37-160899.37 SU). This property is related to the high contents of capsaicin (39.60-44.01 mg/g) and dihydrocapsaicin (32.33-35.95 mg/g). Our results revealed that brittleness, hardness 1 and 2, firmness, chewiness, gumminess appearance and Young’s modulus are very important attributes in determining the textural profile of dried red pepper. Also, drying causes a strong degradation of natural pigments of red pepper and consequently decreases attractiveness of the texture profile. To avoid that, red pepper should be pretreated before the application of hot air drying.
The Analysis of Correlations Between Terpene Transformations and Fermentation Type of Apple Musts
Authors: Januszek Magdalena , Wajda Łukasz 
Published: July 2022

Abstract
We measured the concentration of 13 terpenes in musts of 3 different apple cultivars fermented spontaneously, with Ethanol RED yeast (Saccharomyces cerevisiae) or Cider Yeast (Saccharomyces bayanus). Then we analysed obtained data with PCA with various packages in R to assess how different types of fermentation and apple cultivars affected terpene profile. The most informative results of PCA were obtained in ‘psych’ package and they indicated that there were groups of terpenes which concentrations increased simultaneously, while for some other groups the content of particular compounds was negatively correlated. This suggests that the first group of terpenes originated from different substrates while the latter group could be obtained from the same compound. Our findings indicated new possible pathways of terpene transformation, e.g. linalool, citral and geraniol could transform into one another. Moreover, the role of S. bayanus in those processes remains unclear and it requires further consideration.

Published: July 2022

Abstract
In this study, five plant matrices (pea, mung bean, lentils, soy and sunflower) were fermented using Bacillus subtilis var. natto. Then the process influence on the content of fatty acids and proteins was evaluated, depending on the fermentation length. Fermentation was conducted for 144 hours in controlled conditions of temperature and relative humidity (37°C, 75%). Samples for tests were collected every 24 hours. Gas chromatography coupled with triple quadrupole tandem mass spectrometry (GC-MS/MS) was used to evaluate fatty acids content in fermented seeds. Their composition was expressed as a percentage of the total quantity of fatty acids. The protein content in plant matrices was analysed with the modified Bradford protein assay, using the TECAN apparatus with the i-Control software, of the wave length of ʎ=595 nm. Studies showed that the prolonged fermentation time influenced an increase of polyunsaturated fatty acids (PUFA) content in all studied seeds. Promising results were obtained for soy, sunflower, and lentil seeds, amounting to 3.6%; 68.7% and 67.7%, respectively. This proves that the process of seed fermentation can be effectively used to increase their nutritional value.
ANOVA bootstrapped principal components analysis for logistic regression
Authors: Toleva Borislava 
Published: July 2022

Abstract
Principal components analysis (PCA) is often used as a dimensionality reduction technique. A small number of principal components is selected to be used in a classification or a regression model to boost accuracy. A central issue in the PCA is how to select the number of principal components. Existing algorithms often result in contradictions and the researcher needs to manually select the final number of principal components to be used. In this research the author proposes a novel algorithm that automatically selects the number of principal components. This is achieved based on a combination of ANOVA ranking of principal components, the bootstrap and classification models. Unlike the classical approach, the algorithm we propose improves the accuracy of the logistic regression and selects the best combination of principal components that may not necessarily be ordered. The ANOVA bootstrapped PCA classification we propose is novel as it automatically selects the number of principal components that would maximise the accuracy of the classification model.
The influence of recurrent property income and expenditure on house prices in European Union countries: Evidence from a panel model
Authors: Angelovska Julijana , Časni Anita Čeh 
Published: July 2022

Abstract
Land value capture can be defined as a policy approach that allows communities to restore and reinvest land value increases that result from public investment and other government actions. For that reason, public action should generate public benefit. The recurrent property tax, one of many tools for land value capture, is the foundation of a stable, enduring revenue source that supports the provision of essential housing and amenities services. This empirical paper aims to examine the influence of recurrent property tax income, and general government spending on housing and community amenities on house prices. To assess the hypothesized direction of the effects, yearly data structured in a balanced panel on a sample of 26 European Union economies from 2010 to 2019 was used. Fixed effects regression model with Driscoll and Kraay standard errors was employed and the results confirmed a negative but statistically insignificant effect of increased property tax revenue on house prices, while increased expenditure on housing and amenities confirmed a positive and statistically significant effect on house prices dynamics in European Union countries.
The spillover effect of European Union funds between the regions of the new European Union members
Authors: Maras Marin 
Published: July 2022

Abstract
As the differences between the regions are more pronounced than among the countries, NUTS 2 regions of the new members that joined the EU after 2000 are considered. Due to the presence of externalities between the regions, the Solow growth model using interregional externalities is used. This is modelled by spatial econometrics, the method of maximum likelihood. According to previous research, the effects of European funds in the EU on reducing disparities are not unique, but contradictory. From the mentioned research for new members, we can conclude that the research shows a positive effect of European funds on growth rates. There is a noticeable lack of research analyzing the impact of EU funding on new members after the 2008 crisis, including their mutual regional interaction. The aim is to determine the impact of EU funding on reducing regional disparities as measured by GDP per capita. The paper shows that an increase in European funding increases growth rates, thus contributing to the reduction of interregional disparities. European funding, which is mostly targeted at less developed regions, represents an opportunity for new members and potential new members to move closer to more developed old members. The spillover effect of European funds represents the key contribution to the positive effect of EU funds, i.e. the advantage of the application of spatial econometrics. Also, these spillovers have proven to be an important factor whose omission in models estimated by the OLS leads to bias. Regional externalities should be taken into account in regional divisions by regional policymakers, and in creating the distribution of funds for the next programming period. The effect of funding in the region itself without the spillover effect does not contribute to reducing disparities, which represents a future opportunity, especially for the poorest regions, such as the regions in Bulgaria and Romania.

Abstract
Intense competition in today’s market and quick change in customer preferences, along with the rapid development of technology and globalization, have forced companies to work as members of a supply chain instead of individual companies. The success of the supply chain depends on the integration and coordination of all its institutions to form an efficient network structure. An efficient network leads to cost savings throughout the supply chain and helps it respond to customer needs faster. Accordingly, and with respect to the importance of the supply chain, in this study a developed mathematical model for the design of a green closed-loop supply chain is presented. In this mathematical model, the economic and environmental objectives are simultaneously optimized. In order to tackle this mathematical model, two methods of epsilon constraint and multi-objective gray wolf optimization (MOGWO) algorithm have been applied. The results of comparisons between the two mentioned methods show that MOGWO reduce the average solving time from about 1300 seconds to 88 seconds. In the last step of this research, in order to show the application of the proposed mathematical model and the method of solving the research problem, it was implemented in the supply chain of Dalan Kouh diary product and the Pareto optimal solutions were analyzed.

Abstract
In recent years, the increase in population and the decrease in agricultural lands and water shortages have caused many problems for agriculture and farmers. That is why scheduling is so important for farmers. Therefore, the implementation of an optimal schedule will lead to better use of agricultural land, reduce water consumption in agriculture, increase efficiency and quality of agricultural products. In this research, a scheduling problem for harvesting agricultural products has been investigated. In this problem, there are n number of agricultural lands that in each land m agricultural operations are performed by a number of machines that have different characteristics. This problem is modeled as a scheduling problem in a flexible workshop flow environment that aims to minimize the maximum completion time of agricultural land. The problem is solved by programming an integer linear number using Gams software. The results show that the proposed mathematical model is only capable of solving small and medium-sized problems, and due to the Hard-NP nature of the problem, large-scale software is not able to achieve the optimal solution.

Abstract
The purpose of the research in this article is to investigate the main trends in the development of the different industries during the COVID-19 pandemic, to identify the main problems facing the different industries in the context of the global crisis, as well as to form the basic concepts necessary for a real recovery of the global industry. The authors identify the main problems facing the aviation industry in the developing world crisis and possible ways to solve them. As a working hypothesis, it is proposed to form the basic concepts necessary for preparing and implementing operational measures to restore passenger and cargo aviation. Considering the main threats facing the aviation industry during COVID-19, the article proposes the organizational and economic mechanisms to restore the industry. Furthermore, several recovery scenarios are considered, considering the relevant factors that have a particular impact. Next, a novel mathematical model for pharmaceutical products, which are the most important in COVID-19 pandemics, is proposed. Moreover, the model considers the uncertainty, and a robust optimization approach is applied. The study is based on a comprehensive analysis of documentary data provided by government agencies in several European countries. An analysis of global and Russian passenger traffic for Q1-Q4 (quartile) of 2020 and a development forecast for Q1-Q2 of 2021 is provided. The scenario problems facing the aviation industry in the context of the COVID-19 crisis are identified. There are key concepts necessary to prepare and implement effective measures to restore the aviation industry.
Automatization of Ternary Boolean Algebras
Authors: Kuśmierowski Wojciech , Grabowski Adam 
Published: July 2022

Summary
The main aim of this article is to introduce formally ternary Boolean algebras (TBAs) in terms of an abstract ternary operation, and to show their connection with the ordinary notion of a Boolean algebra, already present in the Mizar Mathematical Library [2]. Essentially, the core of this Mizar [1] formalization is based on the paper of A.A. Grau “Ternary Boolean Algebras” [7]. The main result is the single axiom for this class of lattices [12]. This is the continuation of the articles devoted to various equivalent axiomatizations of Boolean algebras: following Huntington [8] in terms of the binary sum and the complementation useful in the formalization of the Robbins problem [5], in terms of Sheffer stroke [9]. The classical definition ([6], [3]) can be found in [15] and its formalization is described in [4].
Similarly as in the case of recent formalizations of WA-lattices [14] and quasilattices [10], some of the results were proven in the Mizar system with the help of Prover9 [13], [11] proof assistant, so proofs are quite lengthy. They can be subject for subsequent revisions to make them more compact.
Prime Representing Polynomial
Authors: Pąk Karol 
Published: July 2022

Summary
The main purpose of formalization is to prove that the set of prime numbers is diophantine, i.e., is representable by a polynomial formula. We formalize this problem, using the Mizar system [1], [2], in two independent ways, proving the existence of a polynomial without formulating it explicitly as well as with its indication.
First, we reuse nearly all the techniques invented to prove the MRDP-theorem [11]. Applying a trick with Mizar schemes that go beyond first-order logic we give a short sophisticated proof for the existence of such a polynomial but without formulating it explicitly. Then we formulate the polynomial proposed in [6] that has 26 variables in the Mizar language as follows (w·z+h+j−q)2+((g·k+g+k)·(h+j)+h−z)2+(2 · k
3·(2·k+2)·(n + 1)2+1−f
2)2+ (p + q + z + 2 · n − e)2 + (e
3 · (e + 2) · (a + 1)2 + 1 − o
2)2 + (x
2 − (a
2 −′ 1) · y
2 − 1)2 + (16 · (a
2 − 1) · r
2 · y
2 · y
2 + 1 − u
2)2 + (((a + u
2 · (u
2 − a))2 − 1) · (n + 4 · d · y)2 + 1 − (x + c · u)2)2 + (m
2 − (a
2 −′ 1) · l
2 − 1)2 + (k + i · (a − 1) − l)2 + (n + l + v − y)2 + (p + l · (a − n − 1) + b · (2 · a · (n + 1) − (n + 1)2 − 1) − m)2 + (q + y · (a − p − 1) + s · (2 · a · (p + 1) − (p + 1)2 − 1) − x)2 + (z + p · l · (a − p) + t · (2 · a · p − p
2 − 1) − p · m)2 and we prove that that for any positive integer k so that k + 1 is prime it is necessary and sufficient that there exist other natural variables a-z for which the polynomial equals zero. 26 variables is not the best known result in relation to the set of prime numbers, since any diophantine equation over ℕ can be reduced to one in 13 unknowns [8] or even less [5], [13]. The best currently known result for all prime numbers, where the polynomial is explicitly constructed is 10 [7] or even 7 in the case of Fermat as well as Mersenne prime number [4]. We are currently focusing our formalization efforts in this direction.
