Authors: Amrutha G. S. , Kalpashree M. M. , Krishna Dr. K.
Published: October 2022

Abstract: Nanoparticles can be synthesised in an easy and eco-friendly methods using plant extracts. The present study deals with green synthesis and characterization of Copper oxide and Iron oxide nanoparticles using Plumbago auriculata floral extract. In this report, aqueous phase green synthesis of specifically copper oxide and iron oxide nanoparticles utilising the floral parts of this plant is elucidated for the first time. Aqueous floral extract of fresh flowers were utilised for the synthesis of nanoparticles. The aqueous extract acts as both reducing and capping agent. The synthesised oxide nanoparticles of copper and iron were confirmed by the change of colour after addition of floral extracts into CuSO4.5H2O and FeCl3.6H2O solutions respectively. The synthesised nanoparticles were characterised by UV-Visible Spectroscopy and Scanning Electron Microscopy(SEM). The UV/VIS spectroscopy showed the absorption peaks at 346nm and 348nm for Copper oxide and Iron Oxide nanoparticles prepared respectively. CuONPs and IONPs nanoparticles were validated by the SEM analysis and the average size of certain selected particles ranged from 120nm to 200nm. It was observed that the aqueous floral extract can reduce copper and iron ions into oxide nanoparticles within a day. Thus, nanoparticles can be synthesised in a sustainable and nontoxic manner by this method

INTRODUCTION: The main reason, causing failure of the crew, weapon and submarine military equipment and other hermetically sealed craft of military purpose, is fire. The study is a continuation of sets of works aimed at justifying the creation of hypoxic gaseous medium in sealed habitable objects that provide fire prevention.

OBJECTIVE: To study possible long-term effects of extended (for 100 days) man’s stay in regulated hypoxic firesafe gaseous medium for confirming the possibility to perform professional activities by the staff of a sealed craft in such conditions.

MATERIALS AND METHODS: For 12 months after finishing 100-day sealing the volunteers were evaluated for any disease, possible deviation of functional state and working capacity. The examined contingent: 5 men, aged 25– 32, 1 man, aged 53.

RESULTS: No mental and somatic health disorders were found among all the volunteers within a year of observations. Furthermore, no volunteer experienced any decrease in the body’s resistance, quality of life and other deviations that might be a consequence of the sealing negative influence in regulated hypoxic gaseous medium. The results preliminary allow to use technologies of regulated normobaric hypoxic gaseous medium under well-developed regimes for increasing fire safety of submarines and other sealed habitable objects.

Published: October 2022

Introduction: Decompression sickness (DCS) has been associated with unusual circumstances such as breath-hold diving, shallow depths, and short bottom times. We report a case of DCS with an extraordinary cause and course. Materials and Methods: A 72-year-old healthy Hispanic female was referred to our 24/7 Hyperbaric Medicine Unit for emergency hyperbaric oxygen recompression treatment (HBO2 RCT) after developing lower-extremity paralysis following a hyperbaric air exposure in a homemade hyperbaric chamber. Findings/Case report: After an uneventful exposure to hyperbaric air at a maximum 72-foot depth (3.2 ATA, 32.3 psig), the patient had the delayed onset of abdominal pain and paraplegia after eating a meal. After HBO2 RCT in accordance with our management algorithm, the patient had a full recovery. Conclusions: This patient’s presentation and course corresponded to what we label as “disordered decompression” and conformed to our Gradient Perfusion Model. With a finite blood volume and the need to perfuse two “intermediate” tissues simultaneously, we postulate that a “steal” syndrome arose to cause the abdominal and paralysis symptoms.

Despite the plethora of studies on environmental waqf in the literature, research objectives and results are still inconsistent. Therefore, this study maps the literature on environmental waqf to explore future research directions. Based on data from Scopus from 2001 to March 2022, bibliometric analysis using VOSviewer was used to create this mapping research system. This study visualized a map of co-authorship and co-occurrence of keywords. We present several aspects of the literature on environmental waqf, such as the number of publications per year, document type, journal, author, affiliation, country, subject, and topic. The environmental waqf research review is made up of 120 articles written by 160 authors who are affiliated with 116 institutions across 29 countries. These articles were published in 79 sources. The bibliometric results through the analysis of the keywords identified four research streams: waqf in sustainable development, regional planning, waqf governance in the agricultural sector, and cash waqf for welfare improvement. This study proposes future directions for environmental waqf research, focusing on the role of waqf in achieving the goal of sustainable development for environmental stability.

Authors: Yang Chen , Chen Siheng , Wang Jie
Published: October 2022

Ontogenetic colour change in animals is an interesting evolutional
question, which has been studied by evolutionary biologist for decades.
However, the main challenge is how to measure the colour quantitively
and continuously in a full life cycle for lizards. We used the
spectrometer approach to measure the tail colour of Blue-tailed Skink
(Plestiodon elegans) from birth to sexual mature. The spectrometer
approach is simple, fast, and accurate depending on animals’ visual
sense, to measure the tail colour of skink. We showed a strong
relationship between colour indexes (values of L*, a*, b*) and growth
time of skink. Moreover, we found colour rhythms are different between
sexes, which may influenced by their unique behavior strategies between
sexes. Therefore, our study carried out a continuously measuring the
tail colour change from larva to adults to investigate the mechanism for
ontogenetic colour change in reptiles and to explain the potential
factors that driving the dichromatism between sexes in lizards.

Recent Advances in Mechano-responsive Fluorescent Organic and Organometallic Compounds: Structural Diversity, Phase Transformation and Applications
Authors: Wang Chong , Li Yang , Sun Li-Ying , Yu Jian-Gang , Han Ying-Feng
Published: October 2022

Developing smart luminescent materials, especially stimulus-responsive
fluorescent materials, is a goal of great importance, as well as a
challenge. Mechano-responsive fluorescence is a property whereby the
fluorescence characteristics (i.e., emission color, quantum yield, or
lifetime) of a species change as a result of mechanical stimulation. In
general, the said mechanical stimulation causes a phase transition in
the material, and it simultaneously induces a fresh interaction of the
luminous, resulting in a change in the color of the photoluminescence
emission. Therefore, the transition of a material from
crystalline-to-amorphous, from amorphous-to-crystalline, or from a
crystalline to another, as well as the phase transformation of liquid
crystals, can contribute to changes in fluorescence emission triggered
by a mechanic stimulus. This article briefly reviews the development of
such mechano-responsive fluorescent compounds, which consist of organic
or organometallic molecules, and the emerging trends in this research
field.
From alienation to irony: Critical film studies and kynical subversion in Serbian film
Authors: Simic Marina , Nicic Milos
Published: October 2022

In this paper, we will discuss two issues. First, the relation between
political theory and film studies is discussed as the basis for the
emergence of critical film studies and its contemporary transformation.
Second, we consider the kynical subversion and ironic appropriation as a set
of frameworks for understanding the social reality and politics in the
Yugoslav Black Wave cinema as well as in the movies of the contemporary
Serbian cinematography. New forms of popular appropriations of
cinematographic heritage show the ways through which both the very movies
and critical film studies have disassociated themselves from Althusserian
social critique and embraced contemporary ideas of kynical appropriation and
irony as forms of social critique.
Slaying the “political vampire”: Aberration as a socio-political construct
Authors: Trbojevic Danilo
Published: October 2022

The concept of vampirism in the tradition of peasant culture is an inversion
of social norms by individuals or groups, which the community recognizes as
responsible for social problems and crises. ?Vampire? as a social
institution has a role in resolving the crisis, but also manifests power of
the collective and the desirable model of worldview. However, the experience
of field research imposes a perspective that does not perceive the ?vampire?
as a rigid institution, but also an adaptable tool of social or political
communication. By analyzing two cases (performances) of ?murder of a
political vampire? (Josip Broz Tito and Slobodan Milosevic), as a
performance of political communication, I try to point out the crucial
importance of understanding the context, position and motivation of actors
in dialogue. The focus of the analysis is on ?vampires?, the signifier of
the aberrant, who uses vampire symbolism as a means of spreading political
information but also achieving political goals.

Published: October 2022

This article aims to describe the multidisciplinary clinical management of an intrusive luxation case. The clinical case reports the management of crown fracture and intrusive luxation of permanent maxillary incisors. The clinical results and subjective outcomes four years after the trauma and after two years of post-treatment follow-up are presented. An 11-year-old female patient sought dental care at the local University after experiencing dental trauma. Crown fracture of tooth 8 and the intrusion and crown fracture of teeth 9 and 10 were clinically diagnosed. The multidisciplinary treatment performed involved: periodontal surgical procedures; orthodontic traction; endodontic treatment; dental bleaching; and esthetic resin composite restorations. After two years of follow-up, the clinical parameters of the restorations were satisfactory, as well as the periodontal and periapical status. Oral health-related quality of life was assessed before and after treatment using the OHIP-Aes instrument, with a significant improvement in quality of life after treatment. The multidisciplinary approach was an effective treatment for this case of intrusive luxation. The dentofacial function and esthetics were recovered and the patient’s quality of life was improved.
Understanding Schadenfreude through Personality Factors and Relational Aggression
Authors: Erzi Seda
Published: October 2022

The purpose of this study was to explain the mediator role of relational aggression between schadenfreude and personality traits through the path model. Dark traits, agreeableness and hostility as personality factors are thought to be related to relational aggression according to General Aggression Model. Thus, the model was proposed by the author which included direct and indirect effects of personality factors on relational aggression and schadenfreude. 306 adults completed an online survey comprising dark triad, Proactive/Reactive Relational Aggression, agreeableness, and hostility scales and author-generated measure of expressed schadenfreude. Path analysis revealed that schadenfreude was predicted by only reactive but not with proactive relational aggression. Moreover, schadenfreude was predicted by the dark triad indirectly through reactive relational aggression. The dark triad was also predicted by agreeableness and hostility. Although reactive and proactive relational aggression were predicted by agreeableness and hostility, only reactive agression had a mediator role between personality traits (agreeableness, dark triad, hostility) and schadenfreude. Findings and implications for the future research were discussed. Limitations of the current study were also mentioned.

Published: October 2022

Aim. To develop an approach for quantifying the reliability of the wired tripled control channel with common, mixed, and separate cable jackets. Method. Reliability is formalized using block diagrams and dynamic fault trees. Static and dynamic models have been developed to evaluate the reliability indicators of the wired control channel with triple redundancy. The basis for obtaining these models is the state and transitions diagram. Static models are formed using logical-probabilistic expressions. Dynamic models are based on the principles of Markov analysis. Results. For the core failure intensity, which is higher than the intensity of the cable jacket failure, it is shown that a separate cable jacket provides the highest reliability, and a common cable jacket provides the lowest. Accordingly, the mixed cable jacket in terms of reliability occupies an intermediate position with a slight approximation to the separate. Reliability indicators calculated from static models are understated in all three cases compared to those calculated from dynamic models. Although static models give less accuracy, they do not require the structure of sophisticated Markov models. Scientific novelty. The approach for modeling the reliability of control channels with triple core redundancy for cases of separate, mixed and common cable jackets has been improved. Practical significance. The proposed approach is recommended to be used to assess the reliability during the equipment design, the operation of which may endanger the life and health of service personnel. The obtained results are a mathematical basis for studying the reliability of a wired cable channel with three cores, which are protected by reinforcement and cable jacket in different combinations.

Authors:   Lviv Polytechnic National University, Slipchuk Andrii , Jakym Roman ,   Drohobych State Pedagogical University by name I. Franko
Published: October 2022

Aim. Analysis of used bits revealed the effect when the tungsten carbide insert cutter was scrolling around its axis. Therefore, the task was to study the causes of this phenomenon. Hardness was measured followed by setting the hardness distribution gradient in the section of the hole, in order to evaluate the strength parameters of steel in the zone of the hole. Method. Applying a well-tested method, namely the method of successive approximations, we determined the estimate of the standard deviation and the evaluation criterion. Sample averages were checked for homogeneity. For this, we evaluated the character and magnitude of the difference between adjacent sample means. In conducting such an analysis, Student's t test was applied. Results. The obtained data allow us to establish a fact, that the cutting speed within the studied limits does not significantly affect the breakdown’s size of the holes when unfolding the holes in the body of the cones for fitting tungsten carbide inset cutters. The impact of technological parameters on the statistical association between the magnitude of the hole deployment and roughness for the processing surfaces was also studied. Scientific novelty. The analysis showed that the planes of sliding are formed along the neutral lines of tension - compression in the section of the working wedge surface of the tungsten carbide inset cutter. Under adverse conditions, the distribution of stresses in the conjugation "inset cutter - hole" is the sudden emergence of the spread of trunk cracks. This leads to the sudden destruction hard alloy of the inset cutter. Therefore, the accuracy of the connection is crucial. Practical significance. The ovality of the holes must be reduced to 0.02 mm, If you increase the tolerance around the hole, then there is an unfavorable voltage distribution. This leads to the destruction of the conjugate elements of the inset cutter and the hole of the rolling-cutter row. It is necessary to take into account the character of the stress distribution in the closely spaced not only two inset cutters, but groups of inset cutters in the rolling-cutter row.

A POSTCOLONIAL FEMINIST READING OF J. M. COETZEE’S WAITING FOR THE BARBARIANS (2000)
Authors: Sam Christabel Aba , Bonsu Emmanuel Mensah
Published: October 2022

Literary texts and kinds of research have reframed postcolonial experiences to capture several issues in society. On that note, Coetzee’s Waiting for the Barbarians has chalked many successes in gaining the attention of literary scholars to subject the text to interpretation using varied literary approaches, except postcolonial feminism. The postcolonial aspect of the feminist issues in the text is fundamental. The thrust of this paper is to analyse Coetzee’s Waiting for the Barbarians using the postcolonial feminist theory. Guided by three objectives, the study uses the qualitative content analysis method to interpret the text. From the analysis, the study reported that, while objectification and ‘othering’ are characteristic of the representation of females in the text, violence against them is constructed through fear and torture and resisted mainly through silence. Also, the mode of narration influences the presentation of the narrative to readers. Finally, the study offers implications for further research using other literary theories or approaches.

This study wants to analyze the common points and the points of difference between Western and Islamic philosophy. This is qualitative research using the exploratory-analytical method. This study finds that Western and Islamic philosophy has contributed to each other. The common point between Western and Islamic Philosophy lies in transmitting the truth. Meanwhile, we can see the point of difference in three aspects. First is the source of knowledge. Western philosophy comes from reason and the five senses, while Islamic philosophy is not only that but also from authority (al-Quran and al-Sunnah). Second, the characteristics of knowledge. Characteristics of knowledge in Western philosophy, namely, skeptical, rational-empirical, dichotomous, and positivistic-objective; while in Islamic Philosophy, namely, Qur'anic, harmonization of reason and revelation, theocentric, and value point of view. The third is the truth value of knowledge. The truth value of knowledge in Western philosophy is relative, while Islamic philosophies are absolute and some are relative.
Applicability of Structuring at Local Level in Vocational and Technical High Schools in Turkey
Authors: SOMUNCU Ayşe
Published: October 2022

Starting from the 2012-2013 school year, the mandatory education has been extended to 12 years in Turkey. With this policy, students prefer attending general high schools rather than vocational high schools. Even though the companies are in need of young entry-level professionals, the university graduates suffer from unemployment. Due to the lack of financial support the vocational high school education is not able to provide enough graduates for the labor market. This situation causes families and students to have a negative perception towards vocational education. Vocational education needs a local level structure that is congruent with the demands of the educational sector. What is necessary for structuring at the local level is; Circular No. 2016/21 dated 22.11.2016 has been determined in the Vocational and Technical Education School Administrative Board. Provincial Vocational Education Boards were established by Law No. 3308. The Ministry of National Education should strengthen the local level by delegating authority to these boards. As in the education systems of Finland, South Korea and Germany which are examined in this research, the Ministry of National Education can audit these authorities. With Law No. 5508, incentives are given to schools in the industrial zones and students in private vocational high schools. With the same law, private vocational training centers can be opened.

Food security issues in Russia are becoming a priority in the context of an increase in the level of influence of climate risks on all aspects of the economic and social life of society, as well as changes in the political balance of power. The development of agricultural production requires the use of modern technologies and state support for the agricultural entrepreneur in the conditions of the predominance of risky farming zones, which is typical for the territory of the Russian Federation. Insurance is one of the important tools for ensuring the stability, continuity and payback of agricultural production, which has been used for a long time and effectively in many developed countries.

The subject of research in this article is the analysis, generalization and evaluation of the experience of building an agricultural risk insurance system in the EU countries. The object of the study is the territory of Spain, as the country that has achieved the greatest success in using the insurance tool, one of the effective methods of managing agricultural risks. The results of the study are to identify the advantages of the system of organization and interaction of participants in the insurance protection of an agricultural entrepreneur in Spain, which can be adapted for use in Russia.

Leading experts note that over the past ten years, thanks to the transition of the Russian economy to a phase of stable growth, the problem of harmonization of national regulation has begun to emerge. The experience of the most developed Western states in this area can help solve this difficult task.

For the best use of existing experience, it is necessary to carefully analyze global trends, the most effective approaches and methods that foreign countries use in the field of logistics and transport regulation, as well as the possibility of their application in Russia, why the state should regulate the activities of logistics and transport market entities.

Depression is the most frequent mental health problem in older people, and it’s tough to manage because of late-life health issues and cognitive impairment. The study aim to investigate the efficacy of psycho-social intervention for managing depression in older adults and to explore whether types of interventions, specific aspects of the study, and research participants moderate the magnitude of the effectiveness of interventions. we searched different database and followed PRISMA guidelines. Include studies from 2001 to 2021 conducted among the elderly population aged 60 and above. The quality assessment technique developed by the Cochrane Collaboration was used to look for potential sources of bias. Comprehensive meta-analysis is used to analysing effect size. It is found that Psychosocial interventions are effective in reducing depression among older adults. The overall intervention effect size (hedges’ g) was found to be 1.118 (95% CI: 0.835- 1.402), significant at the 0.0001 level. Based on subgroup analysis it is clear that experimental design and severity of depression do not play changes in the effect size of intervention but cognitive impairments can influence the intervention effectiveness.

"Earlier research has established that posttraumatic stress disorder (PTSD) and substance use disorder (SUD) frequently coexist. Aims: Cognitive Processing Therapy was compared to Sertraline and a placebo in an RCT for treating patients with comorbid SUD and PTSD. Methods: 150 patients with SUD and PTSD were interviewed by clinicians and asked to fill out the Clinician-Administered PTSD Scale (CAPS-5), Posttraumatic Stress Disorder Checklist (PCL-5), Beck Depression Inventory (BDI-II), Timeline Follow Back Interview (TLFB), and Brief Addiction Monitor (BAM). Patients were randomly assigned to the following conditions: CPT (n=50), Sertraline (n=50), or Placebo (n=50). Pretreatment, posttreatment, six and, twelve-month follow-up assessments were conducted. Results: When compared to the sertraline group, CPT resulted in much higher reductions in CAPS scores at posttreatment assessment (d=0.93, p < .000). When compared to the control group, CPT considerably reduced PTSD symptoms (the effect size, d=1.9, p < .000). Sertraline resulted in many significant decreases in CAPS when compared to control groups (the effect size , d=1.11, p<.000). At posttreatment, SUD and depression severity were significantly reduced in both CPT and Sertraline groups. After six and twelve months of follow-up, these differences persisted. Conclusion: Comparatively to the control group, CPT and Sertraline significantly decreased PTSD, SUD, and depression."

Due to the socio-economic challenges of the 21st century, a significant role is assigned to innovative teachers. Our research aims to explore the cultural and social factors that support teachers to become innovative. Between 2010 and 2015, teachers in Hungary had the opportunity to formally register their pedagogical innovations. In our interview study-based, we examined the personal and professional life paths of 12 teachers who had formally registered their innovation and compared them with the life paths of 12 teachers who had taught in the same school but had not registered their innovation. The sample was selected from schools in two disadvantaged regions, in equal proportions by county and by type of school. The semi-structured teacher interview transcripts were analysed using Atlas Ti.7 software. The following dimensions of human and social capital accumulation were analysed: family environment, local social network, stages of educational career, and work contact systems. Of the four domains, family environment and local society did not have a decisive influence on the teacher becoming an innovating educator, but extracurricular commitments in higher education, an open and diverse professional network of contacts, and a role definition extended by professional self-actualisation were predictive of innovation.

Zastosowanie metody "brokatowej" w badaniu właściwości mechanicznych okryw nasiennych mrożonego bobu (Vicia faba)
Authors: Gładyszewska Bożena
Published: October 2022

W pracy zaprezentowano metodą „brokatową” badania właciwości mechanicznych materiałów roślinnych. Określono moduł Younga oraz współczynnik Poissona dla okryw nasiennych bobu mroonego. Mikroskopowy obraz losowo osadzonych na powierzchni próbki znaczników przekazywany był do pamięci komputera, co umożliwiało przeprowadzenie analizy zmian nastpujących podczas rozciągania próbki. Metoda ta charakteryzuje się dużą dokładnością pomiaru i może być stosowana także do badania materiałów o dużej wilgotności. Bardzo istotną zaletą proponowanej metody jest jej nieczułość na efekty brzegowe, występujące w pobliu zacisków próbki. Porównano wyniki uzyskane dla bobu mrożonego, świeżego i suszonego. Stwierdzono, że wartości modułu Younga oraz współczynnika Poissona bobu mrożonego są bardzo zbliżone do wartości tych parametrów określonych dla bobu świeżego.
