An Overview of Perceptual Hashing
Authors: Farid Hany
Published: October 2021

It is said that what happens on the internet stays on the internet, forever. In some cases this may be considered a feature. Reports of human rights violations and corporate corruption, for example, should remain part of the public record. In other cases, however, digital immortality may be considered less desirable. Most would agree that terror-related content, child sexual abuse material, non-consensual intimate imagery, and dangerous disinformation, to name a few, should not be so easily found online. Neither human moderation nor artificial intelligence is currently able to contend with the spread of harmful content. Perceptual hashing has emerged as a powerful technology to limit the redistribution of multimedia content (including audio, images, and video). We review how this technology works, its advantages and disadvantages, and how it has been deployed on small- to large-scale platforms.

Authors: Peremitko V.V. , Kolomoyets I.V.
Published: October 2021

Purpose: Experimentally substantiate the influence of the orientation of zones of higher hardness on the wear mechanism of contact surfaces. Design/methodology/approach: Forming of variable composition within the working surfaces of parts is a common way to solve the problem of uneven wear. The tests were aimed at determining the characteristics of the layers surfaced with the orientation of the zones of high hardness. For this different tests and measurements were done. Before the test, samples of 45 steel were surfaced with a preliminary application of titanium carbide paste. Findings: As a result of researches it was found that different ways of the orientation of zones of higher hardness have different influences on the characteristics of a surface. The main conclusion is that the transverse orientation of such zones helps to increase the wear resistance of the surface and to save its original relief. Research limitations/implications: The roughness, wear resistance, zonal hardness, and relief of layers surfaced with the orientation of zones of higher hardness were studied. Practical implications: The results obtained are useful in the field of rolling production and mechanical engineering to avoid the uneven wear of parts and as a result to extend the term of their exploitation. Originality/value: In this paper the model concepts of wear process of surfaces with variable composition and measurements of characteristics of surface considering its local hardening are proposed.

Authors: Bakhy S.H. , Al-Waily M. , Al-Shammari M.A.
Published: October 2021

Purpose: In this study, the free vibration analysis of functionally graded materials (FGMs) sandwich beams having different core metals and thicknesses is considered. The variation of material through the thickness of functionally graded beams follows the power-law distribution. The displacement field is based on the classical beam theory. The wide applications of functionally graded materials (FGMs) sandwich structures in automotive, marine construction, transportation, and aerospace industries have attracted much attention, because of its excellent bending rigidity, low specific weight, and distinguished vibration characteristics. Design/methodology/approach: A mathematical formulation for a sandwich beam comprised of FG core with two layers of ceramic and metal, while the face sheets are made of homogenous material has been derived based on the Euler–Bernoulli beam theory. Findings: The main objective of this work is to obtain the natural frequencies of the FG sandwich beam considering different parameters. Research limitations/implications: The important parameters are the gradient index, slenderness ratio, core metal type, and end support conditions. The finite element analysis (FEA), combined with commercial Ansys software 2021 R1, is used to verify the accuracy of the obtained analytical solution results. Practical implications: It was found that the natural frequency parameters, the mode shapes, and the dynamic response are considerably affected by the index of volume fraction, the ratio as well as face FGM core constituents. Finally, the beam thickness was dividing into frequent numbers of layers to examine the impact of many layers' effect on the obtained results. Originality/value: It is concluded, that the increase in the number of layers prompts an increment within the frequency parameter results' accuracy for the selected models. Numerical results are compared to those obtained from the analytical solution. It is found that the dimensionless fundamental frequency decreases as the material gradient index increases, and there is a good agreement between two solutions with a maximum error percentage of no more than 5%.

Authors: Tomaszewski Ryszard , Klet Jacek , Pethe Karol , Zachurzok Agnieszka
Published: October 2021

Background. Acetabular fractures are rare in children, constituting approximately 1–4.6% of all paediatric fractures.
Material and methods. Nine patients (4 girls and 5 boys) with a mean age of 14.5 years (range, 12–16.5 years) were treated due to acetabular fractures between 2000 and 2020. Most of the fractures were caused by road accidents. Before the patients were qualified for treatment, they underwent a CT scan (all patients) and an MRI scan (8 patients) of the hip. Surgical treatment was used in 6 patients while the other 2 were managed conservatively.
Results. Mean follow-up period was 6.2 years (range, 2–10 years). Bone union was achieved in all patients after 76 days on average (range, 65–90 days). The mean Merle d’Aubigne score at 12 months after treatment was 17.1 points (range, 13–18 points).
Conclusions. The treatment of acetabular fractures in paediatric patients during or after puberty may be the same as in adults. An MRI scan of the hip joint is recommended for assessing the fracture, particularly the triradiate cartilage.

Published: October 2021

Objective: Native plants can be used as additives to replace antibiotics to improve ruminant feed utilization and animal health. An experiment was conducted to evaluate the effects of Gentiana straminea (GS) on nutrient digestibility, methane emissions, and energy metabolism of Simmental calves.Methods: Thirty-two (5-week-old) male Simmental clves, with initial body weight (BW) of 155±12 kg were fed the same basal diet of concentrates (26%), alfalfa hay (37%), and oat hay (37%) and were randomly separated into four treatment groups according to the amount of GS that was added to their basal diet. The four different groups received different amounts of GS as a supplement to their basal diet during whole experiment: (0 GS) 0 mg/kg BW, the control; (100 GS) 100 mg/kg BW; (200 GS) 200 mg/kg BW; and (300 GS) 300 mg/kg BW.Results: For calves in the 200 GS and 300 GS treatment groups, there was a significant increase in dry matter (DM) intake (p<0.01), average daily gain (ADG) (p<0.05), organic matter intake (p<0.05), DM digestibility (p<0.05), neutral detergent fibre (NDF) digestibility (p<0.05), and acid detergent fibre (ADF) digestibility (p<0.05). Dietary GS supplementation result in quadratic increases of DM intake (p<0.01), ADG (p<0.05), NDF intake (p<0.05), and ADF intake (p<0.05). Supplementing the basal diet with GS significantly increased nitrogen (N) retention (p<0.001) and the ratio of retention N to N intake (p<0.001). Supplementing the basal diet with GS significantly decreased methane (CH4) emissions (p<0.01), CH4/BW0.75 (p<0.05) and CH4 energy (CH4-E) (p<0.05). Dietary GS supplementation result in quadratic increases of CH4 (p<0.01) and CH4/DM intake (p<0.01). Compared with 0 GS, GS-supplemented diets significantly improved their gross energy intake (p<0.05). The metabolizable energy and digestive energy intake were significantly greater for calves in the 100 GS and 200 GS calves than for 0 GS calves (p<0.05).Conclusion: From this study, we conclude that supplementing calf diets with GS could improve utilization of feed, energy, and N, and may reduce CH4 emissions without having any negative effects on animal health.

Objective: This study was conducted to identify the functional long non-coding RNAs (lncRNAs) for swine lactation by RNA-seq data of mammary gland.Methods: According to the RNA-seq data of swine mammary gland, we screened lncRNAs, performed differential expression analysis, and confirmed the functional lncRNAs for swine lactation by validation of genome wide association study (GWAS) signals, functional annotation and weighted gene co-expression network analysis (WGCNA).Results: We totally identified 286 differentially expressed (DE) lncRNAs in mammary gland at different stages from 14 days prior to (-) parturition to day 1 after (+) parturition, and the expressions of most of lncRNAs were strongly changed from day –2 to day +1. Further, the GWAS signals of sow milk ability trait were significantly enriched in DE lncRNAs. Functional annotation revealed that these DE lncRNAs were mainly involved in mammary gland and lactation developing, milk composition metabolism and colostrum function. By performing weighted WGCNA, we identified 7 out of 12 lncRNA-mRNA modules that were highly associated with the mammary gland at day –14, day –2, and day +1, in which, 35 lncRNAs and 319 mRNAs were involved.Conclusion: This study suggested that 18 lncRNAs and their 20 target genes were promising candidates for swine parturition and colostrum occurrence processes. Our research provided new insights into lncRNA profiles and their regulating mechanisms from colostrogenesis to lactogenesis in swine.

Sweet potato (Ipomoea batatasL.) is a crop with high market demands because of its well-known health benefits. Limited use of improved clones reduces the crop’s income potential. Plant breeding programs seek to selectgenotypes with good results in a variety of environments by evaluating the interaction effects of genotypes and environments. This study aimed to assess Clone × Growing season effects on morphological and productive parameters of sweet potato clones grown in the municipality of Curitibanos, Santa Catarina, Brazil, in 2016/2017 and 2017/2018. The following clones were evaluated: Brazlândia Rosada, BRS Amélia, Beauregard, BrazlândiaRoxa, and BRS Rubissol. A randomized block design with three replications was used to investigate root length, root diameter, mean root weight, total root number, number of marketable roots, total yield, and marketable yield. Data were subjected to one-way and two-way analysis of variance. Beauregard afforded the largest number of marketable roots and was stable in both growing seasons. Beauregard, Brazlândia Roxa, and Brazlândia Rosada differed in total number of roots between growing seasons. There were no significant differences between growing seasons in mean root weight; BRS Amélia afforded a higher mean root weight than Brazlândia Rosada. Beauregard did not differ in total or marketable yield between growing seasons and provided higher yields than the other clones. BRS Rubissol and Beauregard were found to be the most promising for sweet potato cultivation under the environmental conditions of Curitibanos.

Published: October 2021

This paper presents the application of Moth Flame optimization (MFO) algorithm to determine the best impulse response coefficients of FIR low pass, high pass, band pass and band stop filters. MFO was inspired by observing the navigation strategy of moths in nature called transverse orientation composed of three mathematical sub-models. The performance of the proposed technique was compared to those of other well-known high performing optimization techniques like techniques like Particle Swarm Optimization (PSO), Novel Particle Swarm Optimization (NPSO), Improved Novel Particle Swarm Optimization (INPSO), Genetic Algorithm (GA), Parks and McClellan (PM) Algorithm. The performances of the MFO based designed optimized FIR filters have proved to be superior as compared to those obtained by PSO, NPSO, INPSO, GA, and PM Algorithm. Simulation results indicated that the maximum stop band ripples 0.057326, transition width 0.079 and fitness value 1.3682 obtained by MFO is better than that of PSO, NPSO, INPSO, GA, and PM Algorithms. The value of stop band ripples indicated the ripples or fluctuations obtained at the range which signals are attenuated is very low. The reduced value of transition width is the rate at which a signal changes from either stop band to pass band of a filter or vice versa is very good. Also, small fitness value in an indication that the values of the control variable of MFO are very near to its optimum solutions. The proposed design technique in this work generates excellent solution with high computational efficiency. This shows that MFO algorithm is an outstanding technique for FIR filter design.

Published: October 2021

The article is dedicated to using the methodology of building a decision support system under threats and risks. This method has been developed by modifying the methods of targeted evaluation of options and is used for constructing a scheme of the decision support system. Decision support systems help to make correct and effective solution to shortage of time, incompleteness, uncertainty and unreliability of information, and taking into account the risks. When we are making decisions taking into account the risks, it is necessary to solve the following tasks: determination of quantitative characteristics of risk; determination of quantitative indicators for the effectiveness of decisions in the presence of risks; distribution of resources between means of countering threats, and means that are aimed at improving information security. The known methods for solving the first problem provide for the identification of risks (qualitative analysis), as well as the assessment of the probabilities and the extent of possible damage (quantitative analysis). However, at the same time, the task of assessing the effectiveness of decisions taking into account risks is not solved and remains at the discretion of the expert. The suggesting method of decision support under threats and risks has been developed by modifying the methods of targeted evaluation of options. The relative efficiency in supporting measures to develop measures has been calculated as a function of time given on a time interval. The main idea of the proposed approach to the analysis of the impact of threats and risks in decision-making is that events that cause threats or risks are considered as a part of the decision support system. Therefore, such models of threats or risks are included in the hierarchy of goals, their links with other system's parts and goals are established. The main functional modules that ensure the continuous and efficient operation of the decision support system are the following subsystems: subsystem for analysing problems, risks and threats; subsystem for the formation of goals and criteria; decision-making subsystem; subsystem of formation of the decisive rule and analysis of alternatives. Structural schemes of functioning are constructed for each subsystem. The given block diagram provides a full-fledged decision-making process.

Consolidation of storage into IP SANs (Internet protocol storage area network) has led to a combination of multiple workloads of varying demands and importance. To ensure that users get their Service level objective (SLO) a technique for isolating workloads is required. Solutions that exist include cache partitioning and throttling of workloads. However, all these techniques require workloads to be classified in order to be isolated. Previous works on performance isolation overlooked the classification process as a source of overhead in implementing performance isolation. However, it’s known that linear search based classifiers search linearly for rules that match packets in order to classify flows which results in delays among other problems especially when rules are many. This paper looks at the various limitation of list based classifiers. In addition, the paper proposes a technique that includes rule sorting, rule partitioning and building a tree rule firewall to reduce the cost of matching packets to rules during classification. Experiments were used to evaluate the proposed solution against the existing solutions and proved that the linear search based classification process could result in performance degradation if not optimized. The results of the experiments showed that the proposed solution when implemented would considerably reduce the time required for matching packets to their classes during classification as evident in the throughput and latency experienced.
How to Appropriate a Text
Authors: Piercey Robert ,   Philosophy Documentation Center
Published: October 2021

One of the core principles of Paul Ricoeur’s hermeneutics is that interpretation culminates in application, or appropriation. But what exactly is an appropriation, and what makes some appropriations better than others? I try to shed light on these difficult matters by examining Ricoeur’s own appropriation of Alasdair MacIntyre’s notion of the narrative unity of a life, and by contrasting it with Richard Rorty’s appropriation of the same notion. I argue that Ricoeur’s appropriation is more successful than Rorty’s, and that the best explanation of its success is that it respects a distinctive norm that governs the activity of appropriation. I conclude by describing this norm, which I call the principle of ultimate compatibility.
Aspasia, Foreigner, Intellectual
Authors: Loraux Nicole , Ling Alex ,   Philosophy Documentation Center

The brilliant Aspasia owes her fame to two men. She was the beloved and revered companion of Pericles, the most powerful and prestigious Athenian of the city’s golden age (460–430 BCE), and the privileged and respected interlocutor of Socrates. Her position as a valued companion and recognised intellectual—exceptional in a city where custom dictated that silence and invisibility represented a woman’s greatest glory—was no doubt connected with her status as a metic (resident alien). This status, while denying her the right to become the legal spouse of the man whose life she shared, allowed her—at the risk of a somewhat sulphurous reputation—the freedom to be seen, to think, and to express herself. While the beautiful woman from Miletus has remained silent, if we assume that the insults she was showered with were essentially aimed at her lover, the leader of the democrats, the sources we have at our disposal allow us to study her relationships with Socrates and Pericles.
Refugees and adult education: A thematic analysis on UNESCO's latest recommendations
Authors: Karanikola Zoe , Palaiologou Nektaria
Published: October 2021

Contemporary societies are called to face complex challenges, deriving from globalization, the rapid technological evolutions, the intense demographic changes, and the social exclusion. These challenges are part of UNESCO's global mandate, as reflected in the Education 2030 Framework for Action for the implementation of Sustainable Development Goals, and have more impact on migrations and refugees. UNESCO's Global Report on Adult Learning and Education comes to play a crucial role in achieving the fourth goal of the Agenda, that of education and lifelong education. The present research, through the qualitative analysis of the text of UNESCO (GRALE 4, 2019), aims at pointing out the basic dimensions of adult refugees' education and how it can be applied. Through the analysis of the text certain thematic networks emerge, related with the participation percentages of adult refugees' participation, mapping out of policies, whose particular characteristic is the investment in lifelong learning, transmission of good practices and their evaluation.
Factors of pedagogical (in)competence of parents for the parenting role

Starting with the theoretical considerations regarding the perception of parental competence in the context of changes typical of modern society and the challenging tasks faced by parents, this paper intends to examine particular factors of self-evaluation of pedagogical (in)competence of parents for the parenting role. The sample comprised 575 subjects, including mothers and fathers of pre-schoolers. The attained results demonstrated that mothers perceive themselves as more competent in the parenting role, regardless of the child's sex, and that parents whose children live with both parents deem themselves more competent. Furthermore, we concluded that financial status and whether the child is undergoing pre-school education are additional determinants of parents' pedagogical competence for the parenting role. The following factors were of little relevance in the study sample: the living environment of the child, parent age, number of children in the family and parental educational level. The obtained results are important for shedding light on parental actions in raising children, as well as for underlining possible changes in behaviour and opinions.
The importance of smell and taste in everyday life: Dysfunction in COVID-19 patients
Authors: Stanojlović Olivera
Published: October 2021

Human-to-human transmission of coronavirus (SARS-CoV-2) - COVID-19 (corona virus disease 2019) - is characterized by a pandemic exponential rate and the patients with mild to moderate infection have odor and taste problems that represent a new atypical disease. A new viral syndrome of acute anosmia or "new loss of taste or smell" without rhinitis and nasal obstruction or rhinorrhea has been placed on the list of symptoms that may occur 2 to 14 days after exposure to the COVID-19 virus. Two months after declaring the COVID-19 pandemic in May 2020, the World Health Organization (WHO) has recognized changes in the perception of smell and taste as symptoms of this disease. The described cardinal symptoms are more common in the population of young patients and able-bodied people which facilitates the spread of disease. Significantly higher prevalence of patients with COVID-19 who have lost their taste and smell is treated at home (rare hospitalization), lung damage is rare, as well as oxygen therapy with mild lymphopenia. Different scenarios of SARS-CoV-2 viral infection can be assumed: it is probable that the virus does not enter directly into olfactory sensory neurons (they do not have ACE2 and TMPRSS2 receptors), but it is localized to vascular pericytes and causes inflammatory processes and vasculopathies. On the other hand, direct infection of non-neuronal cells which contain said receptors is possible. Those are specific cell types in the olfactory epithelium such as sustentacular, horizontal basal cells, as well as Bowman's glands, which leads to massive degeneration and loss of olfactory neurons. The sense of taste is a complex sensation that is the result of the interaction of smell, taste, temperature and texture of food. The virus damages cranial nerves, epithelial receptors and blood vessels leading to taste damage (ageusia or dysgeusia). A multidisciplinary approach with epidemiological, clinical and basic research is needed to elucidate the mechanism of sensorineural odor and taste loss caused by coronavirus.
The influence of judicial practice on the legislation in the sphere of LGBT community rights
Authors: Čović Ana
Published: October 2021

In the light of the announced adoption of the Law on Same-Sex Unions, the question arises whether the draft law is in accordance with the Constitution, especially after the announcements that the law will not be signed. Although the Constitution specifies that marriage is a union of a man and a woman, experts point out that in this case it is not a law on marriage and family, nor does it provide for the possibility of adoption of children by same-sex couples, but that it regulates property, health, pension and other legal relationships of same-sex partners living in the union. At the same time, many public figures have invited traditional religious communities to react in order to defend the "right to freedom and future of the people", emphasizing that contentious issues related to the regulation of mutual rights and obligations of same-sex couples could be resolved by amending the existing laws in those areas. In the countries where similar laws exist, case law has played a significant role, just as various medical and psychological associations. The European case law is not uniform, and cases often end before the European Court of Human Rights, while in the United States at the federal level, all anti-homosexual laws are repealed by a Supreme Court decision (Lawrence v. Texas, 539 U.S. 558 [2003]). Nevertheless, there is no single law in this area and the rights of same-sex couples vary from country to country. The paper will provide an overview of significant court decisions in this area in European countries, as well as the decisions of the US Supreme Court, which may lead us to think about the possible legal consequences of (non)adoption of the disputed Law on Same-Sex Unions, about procedures that could be initiated if partners decided to request judicial protection for the purpose of recognizing their guaranteed human rights, as well as the content and significance of such court judgments.
Prospective memory in students with learning disabilities
Authors: Alotaibi Razaan , Ali Kowthar
Published: October 2021

Introduction. The importance of memory is not restricted to remembering the knowledge and experiences of the past retrospective memory (RM), but also to remember what an individual must accomplish in the future prospective memory (PM). Objectives. The aim of this study was to identify RM and PM levels in students with learning disabilities (LD) according to some variables (gender, grade) and to identify the differences between the two types of memories. Methods. The study followed the comparative descriptive statistics. The study sample consisted of 37 male and female students with LD in middle school. The Prospective and Retrospective Memory Questionnaire (PRMQ) was used in this study. Results. The results include the following: a statistically significant decrease from the average in PM and RM levels in students with LD, the existence of statistically significant differences between PM and RM in students with LD for the RM, the presence of statistically significant differences in the PM and RM according to the gender variable for females, and the presence of statistically significant differences in PM and RM according to the grade variable for the third grade of middle school. Conclusion. Students with LD may suffer from a decrease in their capacity to remember in the future, which causes many difficulties in daily life. We guide teachers to use external AIDS for students with LD (such as writing notes) to help students remember performing their tasks.

A partir das obras Cantigas e danças dos pretos, para quarteto de saxofones (1905) e Diálogo Sonoro ao Luar – seresta para saxofone alto e bombardino em Dó, de Francisco Braga (s.d.), de forma sucinta, este trabalho traz à baila a representatividade do saxofone no repertório de câmara do compositor. Para os aspectos que dizem respeito às relações de Francisco Braga e o saxofone, utilizaremos como base os estudos de Oliveira (OLIVEIRA, Jane, 2019) e Macedo (2019). Quanto às interfaces estilísticas, como referência, os trabalhos de Nascimento (2009), Soares (2015) e Cazes (2019).
A internacionalização na perspectiva da educação patrimonial: um projeto no campo da educação musical latino-americana
Authors:   Universidade Estadual de Maringá, Veber Andréia , Yaegashi Solange Franci Raimundo , Díaz Paulina Alejandra Reyes
Published: October 2021

Este texto apresenta reflexões emersas da análise das ações de um projeto de internacionalização desenvolvido em parceria entre duas instituições de ensino superior de dois países latino-americanos: Brasil e Chile, entre 2018 e 2019. Tanto as proposições quanto as discussões apresentadas tomaram como fundamento os princípios da educação patrimonial contemporânea e a ideia de internacionalização proposta por Kertz-Welzel (2018). Como resultado, a análise das ações permite dizer que a internacionalização, quando parte de planejamento colaborativo e integrado com as comunidades participantes, se consolida num processo educativo de construção, identificação e valorização de patrimônios que rompem fronteiras, visando à construção de comunidades de práticas artísticas culturalmente sensíveis e mundialmente conectadas.
