Authors: Djabali S. , Makhlouf F.Z. , Ertas A. , Barkat M. 
Published: December 2020

Abstract
The current research involves the study of the effect of thermal treatment in boiling water (cooking) on the nutrient components and phytochemical contents of lentils. The changes of phenolic compounds and antioxidant activity of lentils before and after cooking; as well as the recovered water are investigated. Total polyphenol, flavonoid and tannin content were determined spectrophotometrically using standards methods and LC-MS/MS. Antioxidant activity of methanolic extracts was evaluated using DPPH (2,2-diphenyl-lpicrylhydrazyl) and ABTS (2,2’-azinobis-(3-ethyl benzo thiazoline-6-sulfonic acid)) assays. As compared to the raw lentils, cooking caused significant (p<0.05) decreases in total phenolic content (TPC), total flavonoid content (TFC), DPPH and ABTS free radicals scavenging activity. The obtained results indicated that the polyphenol content of cooking water was significantly higher than that of cooked and raw lentils; however the most important antioxidant activity was recorded for raw lentils. Several phenolic compounds were identified in fresh, cooked lentils and cooking water. The major compound for the three samples is tannic acid with a very remarkable value in the cooking water; while the minor compounds are naringenin for cooked lentils, apigenin for raw lentils and cooking water. Neoformed compounds have been also detected in the cooking water such as: quercetin, hespritin, tr-caffeic acid and chlorogenous acid in the cooking water.
Gastric impaction: an important health and welfare issue of growing ostriches
Authors: Irfan Muhammad , Mukhtar Nasir , Ahmad Tanveer , Munir Muhammad Tanveer 
Published: December 2020

Abstract
Ostrich farming serves as a source for meat, feathers, skin, eggs, and oil. In general, ostriches are hardy birds that can resist a wide range of climatic harshness and some diseases. However, musculoskeletal and digestive complications, including the gastric impaction, remain the major cause of mortality. The gastrointestinal impaction alone is responsible for 30 – 46% of spontaneous deaths in growing ostriches. The literature review of 21 publications on this subject has shown that 90% of these incidents happen during first six months of life. The aetiology of this problem is mostly stress and behaviour-related gorging of feed and picking on non-feeding materials such as stone, sand, wood pieces, plastic, glass, and metallic objects. Conservative therapy or surgical approaches show good results with almost 70 to 100% recovery depending upon the clinical presentation and timely diagnosis. Overall, this literature review describes impaction in farmed ostriches, along with diagnosis, treatment, and control and preventive measures. This information will help stakeholders understand the gastrointestinal impaction in ratites to better manage this issue, reduce economic losses, and improve welfare of the birds.
On topological properties of the set of maldistributed sequences
Authors: Bukor József , Tóth János T. 
Published: December 2020

Abstract
The real sequence (x
n
) is maldistributed if for any non-empty interval I, the set {n ∈𝕅 : x
n
∈I} has upper asymptotic density 1. The main result of this note is that the set of all maldistributed real sequences is a residual set in the set of all real sequences (i.e., the maldistribution is a typical property in the sense of Baire categories). We also generalize this result.
Evaluation of Histamine Contents during the Fish Meal Production Process
Authors: Mih Hicham , Lacherai Abdellah 
Published: December 2020

Abstract
Evaluation of histamine levels at various stages of manufacturing fish meal made from European pilchard Sardina pilchardus by-products was conducted on two batches which are distinguished by the quality of raw materials expressed through total volatile basic nitrogen (TVBN) content. The goal was also to assess the impact of the reuse of the concentrated stickwater, the liquid from the pressing process of fish meal. The results revealed that the level of raw material deterioration influenced the level of histamine in the finished product. When the freshness of the raw material is acceptable (TVBN content: 30 mg/100 g), histamine contents recorded in the finished product remain clearly below the limit value of 500 ppm. In this case, incorporation of concentrated stickwater into press cake before drying did not affect the concentration of histamine accumulated in the finished product. When the raw material was spoiled (TVBN content: 120 mg/100 g), the recorded histamine content was twice the limit value (975.1 ± 33.9 ppm).
The Dynamic Theory of Time and Time Travel to the Past
Authors: Markosian Ned 
Published: December 2020

AbstractI argue that time travel to the past is impossible, given a certain metaphysical theory, namely, The Dynamic Theory of Time. I first spell out my particular way of capturing the difference between The Dynamic Theory of Time and its rival, The Static Theory of Time. Next I offer four different arguments for the conclusion that The Dynamic Theory is inconsistent with the possibility of time travel to the past. Then I argue that, even if I am wrong about this, it will still be true that The Dynamic Theory entails thatyou should not wantto travel back to the past. Finally, I conclude by considering a puzzle that arises for those who believe that time travel to the past is metaphysically impossible: What exactly are we thinking about when we seem to be thinking about traveling back in time? For it certainly does not feel like we are thinking about something that is metaphysically impossible.
The moral power of the word: Ethical literature in Antiquity
Authors: Paczkowski Przemysław 
Published: December 2020

Abstract
According to an old legend, during the Messenian Wars in Laconia in the 8th and 7th centuries BC, the Athenians sent the poet Tyrtaeus to the Spartans who were close to being defeated; he aroused in them the fighting spirit and renewed Spartan virtues. Philosophers in antiquity believed in the psychagogical power of the word, and this belief provided the foundation for ancient ethical literature, whose main purpose was to call for a spiritual transformation and to convert to philosophy. In this paper, I would like to demonstrate what tradition philosophy referred to in these efforts; what concept of man supported that belief; finally, what literary genres were used by ancient philosophers in ethics.
Ethics of responsibility in Ján Palárik’s civic liberalism
Authors: Martinkovič Marcel 
Published: December 2020

Abstract
The development of the individual attributes of ethics of responsibility in conjunction with the principles of civic liberalism in Slovak political thought is associated with the thinking of Ján Palárik. His political ideas published in the second half of the 19th century come out of an effort to characterize and achieve reform of the Habsburg monarchy on the basis of constitutionalism and federalism. These attributes, in Palárik’s opinion, were to bring more effective solutions to the issue of educating people in their mother tongue and the creation of civic culture. A part of Palárik’s approach to the formation of civic skills is also the advocating of free expression, the idea of pluralism and gradualism within the idea of the unity of the different. His realistic approach to politics was framed by knowing and respecting the objective limits when implementing the aims of national civic freedom. Palárik linked the development of the state and the process of acculturation of the people with application of the principles of practical reasonableness and ethics of responsibility. He found its essence in understanding the interconnectedness of political goals and ideals, which were to be reflected in close association with the real limitations of the capabilities of individuals and social circumstances.
Cultivated character: Voltaire and Karel Čapek on the good gardener
Authors: Brennan Daniel 
Published: December 2020

Abstract
The paper unpacks the nuanced ethical potential in the metaphor of gardening that is depicted in Karel Čapek’s The Gardener’s Year, and the relevance of Čapek’s metaphor for understanding Voltaire’s famously ambiguous ending to Candide. Against more pessimistic or passive accounts of what Candide could have meant, the paper agrees with scholars who consider Candide’s maxim as meaning to engage in active, and communal practise of character development. By using Čapek’s much fuller account of the gardener in the practice of cultivation to fill in the gaps in Voltaire’s account, the paper shows that gardening is a rich metaphor of the virtuous person engaged in lifelong character cultivation.
What is critical in the Anthropocene? A discussion of four conceptual problems from the environmental-political philosophy perspective
Authors: Buschmann Daniel 
Published: December 2020

Abstract
The Anthropocene confronts environmental philosophy with one of the most urgent questions of the 21st century: How to maintain the earth’s condition in a way that allows current and future human generations to thrive? By asking such a question, ethical thought ceases to be solely a matter of individuality or morality. Instead, it raises a political issue: How can or should environmental philosophy relate to society in the Anthropocene? This article argues for a critical perspective that draws on contemporary historic materialist scholars and politicises societal power relations. It exemplifies this approach by discussing key-terms of the Anthropocene discourse, like planetary boundaries, tipping points, and space-ship earth. The article concludes that the idea that “we have to act fast now” would be dangerously too easy because it ignores the ambivalent character of human-nature relations.
Analysis of morphological changes of rural settlement patterns after World War II in the metropolitan area of Łódź using a graph theory based method
Authors: Figlus Tomasz , Musiaka Łukasz 
Published: December 2020

Abstract
This research concerns the complex problem of morphological transformations of villages in the intra-urban area (i.e. settlements incorporated into acity), as well as the suburban area, using the example of the metropolitan area of Łódź, Poland. The main aim of the research was to analyse the diversity of selected rural settlements and their spatial changes after World War II.. The study was based on preserved historical maps and today’s plans. An analysis of morphological changes of selected villages was conducted using graph theory methods. It was noticed that the graph development index should depend on the relative number of edges in relation to the number of nodes and the number of graph cycles, which express the degree of complexity of a settlement unit. Three main groups of villages, characterised by different scales of morphological transformations, were distinguished as a result of the study. Settlement units with orthomorphic transformations, where all spatial modifications were mainly additive and the initial layouts have been preserved almost completely, represent the first group of villages. The second group is composed of units with semi-metamorphic transformations, where the spatial reorganization was significant, but not total. The third group includes villages with metamorphic changes, where the initial layouts have been totallytransformed.
Standardization of complementary work time in timber harvesting processes
Authors: Kamiński Krzysztof , Szewczyk Grzegorz , Kocel Janusz 
Published: December 2020

Abstract
One of the essential elements of work technology assessment is task performance time. In the working day structure, production times are crucial; however, under certain conditions, complementary work times can have a share of up to 30%. Accurate determination of the time structure of a work shift is very time consuming and requires time measurements using the methods of cumulative timing or snapshot observations. For this reason, the overall share of complementary work times in a work shift is usually estimated roughly, equally for all timber harvesting conditions. The aim of this study was to determine the impact of selected working environment factors on the share of complementary work times in a work shift, in technologies on the manual-machine and the machine levels. The analyses were carried out in 33 forest districts of the Regional Directorate of State Forests in Wrocław. Among forest contractors, surveys were carried out to analyse the time structure of a working day. For each forest district, analyses of environmental factors potentially relevant to the share of complementary work times in a work shift were carried out; these included field features, dispersion of stands, features of timber, area accessibility. The total share of complementary work times in the machine-level technology variant amounted to approx. 40% and was higher than the manual-machine technological variant, where this share amounted to approx. 35%. The models developed for standardization of the share of variability of complementary work times, in the case of the manual-machine technology level, took into account the share of timber assortments with the length of over 2.5 m as well as the share of upland and mountain sites. In the case of timber harvesting at the machine technology level, the standardization model included as significant the factors such as the share of coniferous forest sites, the number of forest complexes with an area of over 100 hectares, and the total length of roads. Therefore, the above features could be selected as decisive for the share of the complementary work time category out of the full set of environmental variables taken into consideration in the estimation of the time-consumption of timber harvesting processes.
Perception and Action in Complex Movements: The Emerging Relevance of Auditory Information
Authors: Agostini Tiziano , Sors Fabrizio , Mingolo Serena , Baldassi Giulio , Murgia Mauro 
Published: December 2020

Summary
Recent studies explored the contribution of auditory information in ecological contexts to biological motion perception and its influence on movement execution. This work provides an overview of the most influential scientific contributions in this domain and analyzes the most recent findings, both in sport and motor rehabilitation. Overall, the literature indicates that ecological sounds associated with movements are relevant for perceiving some important features of sport movements. Auditory information is also relevant during performance execution, and can be used to create training protocols. Also, similarly auditory information can be used in clinical contexts to provide rhythmic information to enhance the efficacy of motor rehabilitation protocols. In conclusion, we can say that the role of ecological sounds of movements is examined in conveying complexity of information from a gestalt perspective.
From the Self to the Other and Back Again: Intersubjectivity as a Perpetual Motion Around the Self
Authors: Michalska Anna 
Published: December 2020

Summary
In the methodology of science, intersubjectivity is usually associated with replicability of experimental results. A related, judicial conception of objectivity as impartiality has it that a theory or judgment is objective if it covers all the relevant angles of the object or phenomenon in question, ensuring that the latter is not ephemeral and the concepts referring to them are valid. Based on the assumption that in the social sciences, the researcher is also a participant, an alternative view was conceived, according to the notion that intersubjectivity rests on either sharing of a lifeworld and its associated practices or on empathy, or on some form of direct social cognition.
My aim in this paper is to bring some elements of the Gestalt theory – and more specifically, Rudolf Arnheim’s (1988) adapted model of field dynamics – to bear on the problematic of intersubjectivity. The proposed model suggests that intersubjectivity is a dynamic phenomenon, best described as a product of two vectors: a vector describing a movement across the circumference combined with a vector describing the movement from the center to the circumference. While the first vector corresponds to impartiality, the second represents the tension between cognitive distancing and direct experience. Overall, it is argued that intersubjectivity cannot be divorced from either subjectivity or objectivity and it amounts to skillful navigation within different frames of reference.

Abstract
The research aims to measure the effectiveness of the strategies of modern retailers which implementing reverse logistics activities, and to be believe that it could increase not only business competition, but also consumer satisfaction. The object of research is 20 modern retailers ranging from convenience stores to hypermarket stores. The methodology implemented in the form of setting parameters and assessment criteria which are arranged in the form of priority scale and analyzed using the Analytical Hierarchy Process or AHP method. The respondents are the decision makers in terms of product delivery, logistics, distribution and warehouse including making purchases both directly and indirectly. Sub parameters and sub criteria that are arranged then reevaluated using the ExpertChoice instrument to see the resulting scale consistency. Broadly speaking, the highest priority scale was 0.441 for the criteria for agility, 0.428 for the efficiency criteria, 0.318 for the stakeholder criteria, 0.271 for the process criteria and 0.146 for the environment criteria. The result of simulation cost is less than 8 percent of the profit margin per product returned.
Simēk in Modern Chuvash Ritual Culture
Authors: Iagafova Ekaterina 
Published: December 2020

Abstract
The paper* describes the features of the Simēk ritual (compare semik in Russian) in different ethnic and religious (Orthodox Christian, ‘pagan’, Muslim) and ethnic and territorial groups of Chuvash. The author shows the key role of Simēk in the structure of rituals of the semik and Trinity block and reveals its links with funerary, commemorative and wedding rites. Simēk is one of the main rituals on the Chuvash ritual calendar. Traditionally, it is associated with commemoration customs of the people and is one of the three compulsory days of commemoration of family ancestors. It corresponds to semik in the Russian ritual calendar and is held either on Thursday (for unbaptised Chuvash) or on the Saturday before Trinity (for the majority of Orthodox Chuvash). Today Simēk is performed in the villages as a commemoration ritual with a visit to the cemetery, which involves both villagers and those family members who live in cities. After visiting the cemetery family members conduct visits, turning a commemoration ceremony into a festival. Thus, Simēk strengthens family links between villagers and city dwellers. With increasing levels of religiosity in society the importance of Simēk as a means of preserving and spreading ethnic traditions has also increased. In modern rituals there is some structural transformation of Simēk among the Orthodox community, but at the same time it is possible to trace the actualisation and expansion of the ritual together with the general trends in unification of the Chuvash ritual complex.
Morphological and Physiological Traits in Seedlings’ Populations Obtained from the Hybridization of Promising Genotypes of Quince (Cydonia oblonga Mill.)
Authors: Tatari Maryam , Jafari Azam , Najafi Solari Hojat 
Published: December 2020

Abstract
Some morphological and physiological traits of seedlings in eight quince populations from seeds obtained in 2015 (350 progenies per population) were evaluated in 2017 and 2018. They resulted from open pollination of ‘Viduja’, KVD2 and KVD4 genotypes as well as from the crossings of ‘Viduja’ × KVD4, KVD2 × ‘Viduja’, KVD2 × KVD4, KVD4 × ‘Viduja’ and KVD4 × KVD2. Populations showed significant differences in some measured traits, including height and diameter of seedlings, canopy width, annual growth, leaf iron, and chlorophyll content, as well as catalase and peroxidase activities. Based on the results of descriptive statistics, a high variation coefficient was observed in canopy width, peroxidase activity, chlorophyll, and iron content traits. Results of simple correlation showed that there were significant positive correlations between leaf iron content and catalase activity as well as canopy width with both annual growth and leaf length. Cluster analysis among populations based on total traits divided the populations into four distinct groups. The role of the female parents was visible in reciprocal crosses of ‘Viduja’ × KVD4 and KVD2 × KVD4, but all populations with similar female parents were not grouped in the same clusters.
Measures to Achieve the Energy Efficiency Improvement Targets in the Multi-Apartment Residential Sector
Authors: Upitis M. , Amolina I. , Geipele I. , Zeltins N. 
Published: December 2020

Abstract
Directive (EU) 2018/2002 of the European Parliament and of the Council amending Directive 2012/27/EU on energy efficiency sets a target of 32.5 % energy efficiency to be achieved by 2030, with a possible upward revision in 2023. The directive also stipulates that the obligation to achieve annual energy savings must continue to be met after 2020. In addition, a revised directive on the energy performance of buildings was adopted in May 2018. It includes measures to speed up the renovation of buildings and the transition to more energy-efficient systems, as well as to improve the energy efficiency of new buildings, thus using smart energy management systems [1].
Buildings consume the most energy and have the greatest energy saving potential. They are therefore crucial to achieving the European Union’s energy saving targets. The EU allocated around 14 billion EUR to improve the energy efficiency of buildings in the period of 2014–2020, of which 4.6 billion EUR was intended for residential buildings. In addition, the Member States have earmarked 5.4 billion EUR of public co-financing for the improvement of all types of buildings, of which around 2 billion EUR is allocated to residential buildings.
Multi-apartment residential buildings in Latvia are in a technically unsatisfactory condition. In Latvia, the service life of multi-apartment residential buildings has been artificially extended. In addition, there is also the problem of reduced construction quality. Housing problems affect all layers of society, but they are most acute for low- and middle-income people.
The aim of the research is to study, using the co-financing of the European Union Structural Funds, the activities performed during the renovation process of multi-apartment residential buildings in Latvia and to identify the shortcomings.
