Published: April 2021

Background and aim

Trials of treatments for non-alcoholic steatohepatitis require endpoint assessment with liver biopsies. Previous large-scale trials have calculated their sample size expecting high retention but on average did not achieve this. We aimed to quantify the proportion of participants with a valid follow-up biopsy.

Methods

We conducted a systematic review of MEDLINE and Embase until May 2020 and included randomized clinical trials of any intervention in non-alcoholic steatohepatitis with at least 1-year follow-up. We were guided by Cochrane methods to run a meta-analysis with generalized linear mixed models with random effects.

Results

Forty-one trials (n = 6,695) were included. The proportion of participants with a valid follow-up biopsy was 82% (95%CI: 78%-86%, I2 = 92%). There was no evidence of a difference by location, trial length, or by allocated treatment group. Reasons for missing follow-up biopsies were, in ranked order, related to participants (95 per 1,000 participants (95%CI: 69–129, I2 = 92%), medical factors, protocol, trial conduct, and other/unclear. Biopsy-related serious adverse events occurred in 16 per 1,000 participants (95% CI: 8–33, I2 = 54%). No biopsy-related deaths were reported.

Conclusions

The proportion of participants with a valid follow-up biopsy in therapeutic trials in non-alcoholic steatohepatitis is on average 82%, with around 1 in 10 participants declining a follow-up biopsy. These findings can inform adequately-powered trials.

Published: April 2021

Background

Exposure to maternal stress in utero is associated with a range of adverse outcomes. We previously observed an association between maternal stress and white matter microstructure in a sample of infants born prematurely. In this study, we aimed to investigate the relationship between maternal trait anxiety, stressful life events and brain volumes.

Methods

221 infants (114 males, 107 females) born prematurely (median gestational age = 30.43 weeks [range 23.57–32.86]) underwent magnetic resonance imaging around term-equivalent age (mean = 42.20 weeks, SD = 1.60). Brain volumes were extracted for the following regions of interest: frontal lobe, temporal lobe, amygdala, hippocampus, thalamus and normalized to total brain volume. Multiple linear regressions were conducted to investigate the relationship between maternal anxiety/stress and brain volumes, controlling for gestational age at birth, postmenstrual age at scan, socioeconomic status, sex, days on total parenteral nutrition. Additional exploratory Tensor Based Morphometry analyses were performed to obtain voxel-wise brain volume changes from Jacobian determinant maps.

Results and conclusion

In this large prospective study, we did not find evidence of a relationship between maternal prenatal stress or trait anxiety and brain volumes. This was the case for both the main analysis using a region-of-interest approach, and for the exploratory analysis using Jacobian determinant maps. We discuss these results in the context of conflicting evidence from previous studies and highlight the need for further research on premature infants, particularly including term-born controls.
Understanding the diagnostic delays and pathways for diabetes in eastern Uganda: A qualitative study
Authors: Kasujja Francis Xavier , Nuwaha Fred , Daivadanam Meena , Kiguli Juliet , Etajak Samuel , Mayega Roy William
Published: April 2021

Background

Type 2 diabetes is rapidly becoming a significant challenge in Uganda and other low and middle-income countries. A large proportion of the population remains undiagnosed. To understand diagnostic delay, we explored the diagnostic pathways for diabetes among patients receiving care at a semi-urban district hospital in eastern Uganda.

Methods

Eligible participants were patients aged 35–70 years receiving care at the diabetes clinic of Iganga district hospital between April and May 2019 and their healthcare providers. Patients were interviewed using an interview guide to collect information on patients’ symptoms and their diagnostic experience. A separate interview guide was used to understand the organisation of the diabetes services and the diabetes diagnostic process at the hospital. Using maximum variation purposive sampling, we selected 17 diabetes patients aged 35–68 years, diagnosed within the previous three years, and the three health workers managing the diabetes clinic at Iganga hospital. The data was analysed using ATLAS.ti version 8 to code, organise and track the data segments. We conducted template analysis using a priori themes derived from the intervals of Walter’s model of Pathways to Treatment to identify the factors influencing diagnostic delay.

Results

We identified four typologies: a short diagnostic pathway, protracted appraisal pathway, protracted appraisal and diagnostic interval pathway, and delayed treatment pathway. The pathways of patients with protracted appraisal or diagnostic intervals demonstrated strong socio-cultural influences. There was a firm reliance on traditional healers both before and after diagnosis which deferred enrolment into care. Other health system barriers implicated in delayed diagnosis included stock-out of diagnostic supplies, misdiagnosis, and missed diagnosis. Denial of diagnosis was also found to lead to delayed initiation of care.

Conclusion

Reducing diagnostic delay requires addressing both negative socio-cultural influences and the adoption of system-wide interventions to address barriers to timely diagnosis.
Healing touch: Using the arts to increase healthy touch between people with PMLD and their carers
Authors: Elliott-Graves Leonie
Published: April 2021

For adults with learning disabilities, touch is a necessary element of their everyday care. Yet touch delivered by care providers is a contentious and marginal practice, which is often avoided due to fears of abuse allegations, and the effects of touch avoidance can be significantly detrimental to the quality of care provided. The Safe Touch pilot project, developed with a London-based organization providing care to adults with learning disabilities, including those with profound and multiple learning disabilities (PMLD), used performing arts practices and massage to help the staff develop and utilize ‘positive’ touch – touch for communication, interaction and well-being – when working with service users. Fifteen service users with learning disabilities and PMLD along with the organization’s staff participated in the project. Drawing on the project’s processes and findings, some successes and limitations in employing performing arts activities with care staff to increase the use of positive touch with people with PMLD were identified.
A geoparkok szerepe a geoturizmusban, különös tekintettel a hazai helyzetre = The role of geoparks in geotourism and with special regard to the domestic situation
Authors: Pappné Vancsó Judit , Nagy Mónika , Bazsó Tamás
Published: April 2021

A geoturizmus mind hazánkban, mind világviszonylatban dinamikusan fejlődő jelenség, amely gyakran a tematikus bemutatóhelyekhez, geoparkokhoz köthető. A már meglévő turizmusformákhoz képest a geoturizmus újdonságértéke a földtudományos bázison nyugvó, azonban mégis komplex, a geológia és az arra épülő élő-, valamint épített környezet összefüggéseit egyaránt vizsgáló szemlélet, ahol földtudományi értékeink védelme kap elsődleges fontosságot. Hazánk két UNESCO Globális Geoparkjának közel tíz éve tartó működése mérhető pozitív változásokat eredményezett az érintett területek látogatottságában. Félő azonban, hogy az UNESCO rangot elérni nem, vagy csak nehezen tudó, de megismerésre és védelemre méltó értékekkel rendelkező tájaink földtudományi-és kultúrtörténeti kincsei – a védettségüket garantáló kategória nélkül – rejtve maradnak. A Magyar Geopark Bizottság által kidolgozott Nemzeti Geopark Koncepció a fenti problémát hivatott orvosolni.

Impact Behavior of Fiber-Reinforced Concrete with Polypropylene Fibers and Carbon Fiber–Reinforced Polymers
Authors: Kheyroddin Ali , Arshadi Hamed , Salehzade Jalil
Published: April 2021

In this study, the influences of bidirectional carbon fiber–reinforced polymer (CFRP) confinement along with polypropylene fibers on the impact resistance of concrete samples were experimentally studied. Forty-nine concrete cylindrical samples (with compressive strengths of 20, 30, and 40 MPa) with polypropylene fibers (with content ratios of 0 %, 1 %, 1.5 %, and 2 %) were subjected to weight (46.7 and 66.8 kg) dropping at a height of 1.6 m above the cross-section of the sample. Moreover, half of the samples were tested with CFRP confinement. The number of weight releases required to destroy the samples and the weights of the samples after each release were recorded. The results indicated that the concrete without fibers and fiber-reinforced polymers (with compressive strengths of 20, 30, and 40 MPa) did not have sufficient impact resistance and were swiftly destructed. However, as the content ratios of polypropylene fibers increased, the number of cracks and weight droppings (to reach 70 % of the initial sample weight) increased. Moreover, it was observed that the concrete samples wrapped with the CFRP sheets also withstood impact loading better than fiber-reinforced concrete samples without the confinements. Besides, it was indicated that the prevailing failure mode of the samples with CFRPs was CFRP rupturing. Finally, it was observed that the more the compressive strength of concrete, the more the impact resistance.
How Do You Play When You’re Prey?
Authors: Thomas Natasha
Published: April 2021

Creativity is woven into the culture of Black America. Our histories and struggles as members of the minoritized African Diaspora are recorded and passed on in song and story, in movement and design. We are – and have been – the creators of an evolving culture that is simultaneously underestimated and desired by dominant culture. This othering poses real and pressing threats to our lives and livelihoods, as we are consumed and exploited to the point of erasure; and yet we keep creating. But why? What is creativity to the Black American living in such a predatory society? And how do I, as a Black creative minoritized in a Healing profession, engage with it? How do you play when you’re prey? These questions form the basis for an heuristic exploration into a video blog project entitled “Black Creative Healing,” where Black creatives are recorded engaging in conversation and collaboration over concepts relating to Blackness, Creativity, and the Healing process. Through arts-based analysis of past collaborations, available publicly on Youtube, I will investigate my own motivations, inspirations and roadblocks to the creative process as a Black healer. I will interrogate the directions and intentions laid bare by my creative endeavors and seek to define a central ethos by which other Black creatives may find themselves seen and encouraged, in the interest of finding balance between the “me” that is – and has been – prey, and the “me” that has only ever known – and been known by – play.
Song as a Register for Black Feminist Theatre-Making Aesthetic
Authors: Lepere Refiloe
Published: April 2021

This article looks at the play, Dipina tsa Monyanyako, which was made with a group of domestic workers in South Africa. The article explores how song is used as a strategy to locate ways of creating and making in South Africa. Song therefore registers a historical way of imagining and how marginalised groups; women have written themselves into history.
The production is a creative conversation where song is used to express care and anger in everyday life. Current approaches to knowledge production are inadequate in capturing song, poetics, and interpreting the forms of performances black women engage. The article makes a case for song as a form of black feminist theatre-making aesthetic. Using Dipina tsa Monyanyako, I argue that songs, silence, sighs have important methodological implications for arts-based processes and research.
In post-apartheid South Africa, performances are characterized by constant aesthetic reinvention. From precolonial expressions of life to protest theatre, performance aesthetics have been a way of revealing everyday life and struggles. For black women, theatre becomes the meeting place of the expression of their lives and a space of reflection and analysis of those lives, even though, historically, the presence of black women in theatre has been minimal. The creation of Dipina tsa Monyanyako allowed for the emergence of women as empowered subjects, and song became a portal for collective transformation.
Navigating Privilege and Colorism
Authors: Napoleon Johannil
Published: April 2021

Discussions about cultural responsiveness for mental health practitioners often perpetuate colonizing frameworks. By centering White therapists’ awareness of power and privilege when working with people of color, dominant paradigms in the field can overlook the experiences of practitioners of color and the relational dynamics of engaging shared racial/cultural backgrounds. Interrogations of Whiteness are necessary to prevent harm in the predominantly White fields of the creative arts therapies, yet this discussion should not overshadow discussions about the experiences of practitioners of color who encounter issues of colorism and citizenship in working with communities of color. This self-reflexive essay describes how a Black Dominican-Haitian woman art therapist, who was raised in the United States (U.S.), recognized a need to explore her own political awareness while working with female participants at a youth organization in the Dominican Republic (D.R.). The author discusses the use of art to critically interrogate issues of colorism, citizenship, and privilege that arise during her time in the D.R. Recommendations are presented to support arts therapists of color to engage their perceptions of citizenship and colorism while providing mental health services to communities of color.

Published: April 2021

In this viewpoint, the authors describe their impressions of a 2018 conference and the significance of participating in a learning environment that centered on arts therapists of color. Collectively, two art therapy educators, a music therapy educator, one new professional art therapist, and one art therapy graduate student, question the maintenance of professional norms that have at times motivated BIPOC students and practitioners to leave the creative arts therapies in search of other professional places to thrive. The article concludes with a Womanist Manifesto for Arts Therapies Education.

Industrial upgrade, economic catch-up and industrial policy in Brazil: general trends and the specific case of the mining industry
Authors: Garcia Renato , Santos Ulisses Pereira dos , Suzigan Wilson
Published: April 2021

Abstract The aim of this paper is to analyze the role of industrial policy in promoting technological upgrading in Brazil. To do that, we focus on the main characteristics of the Brazilian national innovation system and the role of its institutions. We examine whether industrial policy implemented between 2003 and 2014 was able to promote changes in agents’ conventions towards more vigorous strategies linked to technological upgrading and catch-up. In addition, we analyze the Brazilian mining industry, a sector in which Brazil has developed relevant competitive advantages in international markets, and in which domestic agents have built important operational capabilities. Main results show the huge difficulties faced by industrial policy efforts in establishing mechanisms to drive technological catch-up, based on the unsuccessful experiences of policies in the years 2002 to 2014. The specific experience of the Brazilian mining industry confirms these general findings, since domestic mining companies were not able to create new technological capabilities, even during the commodity price boom period.
Subcutaneous and muscular lagochilascariasis in a cat from Rio Grande do Sul, Brazil
Authors: Lucio Bruna Marquardt , Flores Mariana Martins
Published: April 2021

ABSTRACT: A domestic cat was submitted to necropsy with a small abscess within the subcutaneous tissue and skeletal muscles dorsal to the left ear. It contained multiple 0.8 to 1.2 cm-long adult nematodes and was drained by two cutaneous fistulae. On histopathology, multiple cavitary areas within the skeletal muscles and subcutaneous tissue contained adult nematodes and were surrounded by thick fibrotic and chronic-active inflammatory reaction. The parasites were externally lined by a smooth cuticle and had two prominent lateral alae. They contained an intestinal tract and a pseudocoelom. A prominent polymyarian-coelomyarian musculature and two large lateral chords were identified, and some sections contained a uterus with multiple non-operculated eggs. Lagochilascariasis should be considered a differential diagnosis for cervical skin abscesses in domestic cats from Southern Brazil. This article brings important contributions to the clinical and anatomopathologic diagnosis of this rare zoonotic disease.

Briefing: Pyrolysis of natural gas to hydrogen: a key energy transition tool
Authors: Clarke Richard , Abánades Alberto
Published: April 2021

To achieve a low carbon dioxide (CO2) energy future the fossil fuel industry must pivot to make zero-emissions hydrogen through an open, global collaboration. One track to this is ‘pyrolysis’ in which natural gas is split into ‘white’ hydrogen and carbon black. This avoids the need for a massive roll-out of carbon capture and storage sites as envisaged in natural gas reforming or ‘blue’ hydrogen schemes. The advantages of both options are needed to support longer-term efforts to move towards ‘green’ hydrogen where water is split into its elements. By leading the development of all these routes to hydrogen, the energy majors of today will be able to utilise their enormous resources, technical ingenuity and vast capital and lead the future of energy. With the COP26 climate conference just months away, the UK has a critical role in directing efforts to bring hydrogen to the fore both at home and abroad.
Cultural Importance of the 4th International Chopin Piano Competition in the Light of Polish Music Life Reviving after the WW II
Authors: Popiołek-Walicki Aleksandra
Published: April 2021

The article aims at summarizing different activities undertaken to organize and run the first post- war Chopin piano competition. It is an attempt to collect facts, accounts and memories concerning actions initiated by Polish music culture environment after the Second World War. The author fo- cuses on a detailed description of the organization and proceedings of the 4th International Piano Competition, making use of information that has existed in independent sources so far. The article uses diaries, biographies, autobiographies, private notes, interviews with representatives of Polish culture, archive films and documentaries belonging to the Polish Film Chronicle. Press excepts were not used on purpose, as most press information was included in the aforesaid bibliography entries. The analyzed sources let us conclude that the organization of the first post-was Chopin piano competition in Warsaw was an event requiring both the engagement of all state institutions and personal contribution of musicians and music teachers. The author considers such a detailed historical-cultural account justified and necessary, especially in 2020, the 210th birth anniversary of Frederic Chopin, the year in which the 18th Frederic Chopin International Piano Competition was supposed to take place.
Guitar – a Sound Episode in the Output of Les Six Group
Authors: Wojtuch Wojciech
Published: April 2021

The article aims at presenting the guitar output of the composers who were members of Les Six group. It may trigger further, detailed research into the guitar works of composers for whom this instrument became a mere sound episode in their oeuvre. Four of the six French composers included in this group: Georges Auric, Darius Milhaud, Francis Poulenc, and Germaine Tailleferre dedicated a part of their oeuvre to the guitar literature renascent in the first half of the 20th century. Their interest in the instrument was the result of the activity of the great masters of the time, Andrés Segovia and Ida Presti. It also resulted from their specific approach to creation - among other things, a desire to oppose the previous aesthetics or to write simple and humorous music, in which the guitar proved to be an excellent medium. The article contains an analysis of selected compositions and the genesis of their creation. The analysis also focuses on the role of the guitar in French music throughout the ages and the programmatic ideas of the group known as Les Six.
Caught in the Regime: Classical Music and the Individual in the Contemporary Novel
Authors: Harling-Lee Katie
Published: April 2021

The twenty-first century has seen the identification and development of a new literary genre: the musico-literary novel, defined as a novel thematically concerned with music (Harling-Lee, 2020). As a comparative case study, this article considers two musico-literary novels set during conflict: Do Not Say We Have Nothing (Thien, 2016) and The Noise of Time (Barnes, 2017). Set, respectively, in Communist China and the Soviet Union, two communist regimes which historically targeted classical music and musicians, the novels use their conflict contexts as a springboard to explore existential—and existentialist—crises concerning the survival of the self in relation to music. Following Adler and Ippolito’s proposal that ‘extreme cases are valuable in revealing phenomena that are often camouflaged in less extreme … more familiar circumstances’ (Adler and Ippolito, 2016), analysis of the novels’ representations of classical music reveals the powerful potential that music is presumed, by the popular imagination, to offer. With a focus on individual composers and performers, the novels depict classical music as a source of personal identity that is relied upon by individuals for personal and existential expression; for when the state threatens a character’s musical life in these novels, it also threatens a character’s sense of self. Due to the legacy of absolute music, classical music is seen as a source of hope through its potential autonomy from ‘meaning’ even as it promises to be a refuge for the self, embodying a paradox that becomes central to the representation of western classical music in the popular imagination of the contemporary musico-literary novel. 
Accelerometery vs. video-derived stroke parameters in high-level swimmers
Authors: Courtney Musson  , Mark Kramer
Published: April 2021

Background: Swimming is a multifaceted sport with nuanced performance parameters that tend to vary according to the swimmer’s stroke style. The extraction and analyses of swim parameters, such as lap time (LT), stroke length (SL), stroke rate (SR) and velocity are time-consuming. This may be eased and to some extent automated by the use of cost-effective tri- axial accelerometers.

Objectives: To determine the validity of tri-axial accelerometers across all four stroke styles, and to investigate kinematic differences in stroke styles using accelerometer- based data.

Methods: Twelve elite swimmers were recruited for the study. The group consisted of five male (age: 22.2 ± 2.6 years; height: 1.84 ± 0.08 m; weight: 76.2 ± 3.6 kg) and seven female (age: 20.7 ± 2.1 years; height: 1.68 ± 0.08 cm; weight: 62.0 ± 6.3 kg) swimmers.

Results: There was a small but significant bias for accelerometery data compared to video data across most parameters and stroke styles except for stroke length and stroke count (p > 0.05). However, accelerometery-derived SR, SL and velocity can be considered practically useful based on the training requirements of coaches. Parameters derived from video analysis compared to accelerometery were highly correlated (r > 0.91) and therefore consistent regardless of the method of analysis.

Conclusion: Although slight differences were present between the video and accelerometer data, these differences were not practically meaningful.
La educación superior de Colombia en riesgo: ¿dónde están los estudiantes?

Published: April 2021

Los medios especializados en el sector de la educación superior en Colombia hablan de la caída de su demanda, ¿pero a qué hace referencia esta afirmación? ¿Qué se entiende cuando se habla de la “caída”? Diferentes hipótesis se han aceptado tácitamente como explicación, entre las principales se encuentran el cambio demográfico, el aumento de precios en las matrículas y una disminución de los ingresos de las familias. Pero ¿qué tan ciertas son y qué tanto impactan en la caída? En este estudio se estableció una metodología que permite abordar la respuesta mediante un enfoque cuantitativo en el análisis exploratorio y descriptivo en los datos administrativos de las entidades oficiales en Colombia. Se encontró que las hipótesis relacionadas con el entorno socioeconómico y el financiamiento explican mejor la caída y contracción de la demanda en la educación superior.
Current Views on the Genetic Markers of Post-Traumatic Stress Disorder
Authors: Faustova A.G.
Published: April 2021

The article summarizes empirical studies on the problem of genetic predisposition to post-traumatic stress disorder. It is showed that the development of some symptoms of post-traumatic stress disorder is caused by neurobiological mechanisms, the functioning of which depends on the expression of specific genes. Differences in the effectiveness of the use of certain types of psychological assistance can also be associated with the influence of genetic factors. A review of the most relevant patterns is presented. More specifically, this is the effect of the gene of brain-derived neurotrophic factor (BDNF) as well as the genes of serotonergic (SLC6A4, SLC6A3), dopaminergic (DRD2, COMT), hypothalamic-pituitary-adrenal (FKBP5, ADCYAP1) systems on the manifestation of symptoms of post-traumatic stress disorder. Based on the results of genome-wide association studies, assumptions are made about the role of genes (RORA, NLGN1, TLL-1, PARK2, PODXL, SH3RF3, and ZDHHC14) in the pathophysiology of post-traumatic stress disorder. The issue of the applicability of genetic testing in the practice of psychological assistance to individuals with post-traumatic stress disorder is considered. The question of the applicability of genetic testing to improve the diagnosis and development of a personalized strategy for clinical and psychological intervention is discussed.
The Phenomenon of Anti-Doping Policy Legitimacy in the Social Psychology of Sports
Authors: Bondarev D.V. , Bochaver K.A. , Barkoukis V.
Published: April 2021

Anti-doping represents a global system where an athlete is in the center of a control and regulations. The perception of legitimacy is important for compliance with rules and regulation within the anti-doping system. However, the concept of legitimacy in anti-doping is not sufficiently defined, which makes it difficult to develop psychodiagnostic tools for its assessment within the framework of relevant psychological theories. The aim of this study is to review psychological literature on legitimacy perception and identify a framework within which legitimacy can be studied in anti-doping area. Reviewed data were structured by three categories of legitimacy: “proper”, “just” and “appropriate” and a respective matrix for a focus group interview had been developed. Four focus-group interviews had been conducted among Russian competitive athletes (N=22). The focus-group interviews revealed three main themes: trust to anti-doping organizations, equal and transparent anti-doping rules and possibility for athletes to influence anti-doping policy. Legitimacy of anti-doping is an important psychological construct that may be operationalized through the perception that anti-doping is functioning proper, just and appropriate. In addition, athletes voiced their concerns on the transparent and equal implementation of the anti-doping rules and possibility to influence anti-doping policy.

Published: April 2021

The COVID-19 pandemic compounds stressors of daily life among American Indian/Alaska Natives. This study investigated the impact of COVID-19 among American Indian/Alaska Natives and non-Hispanic whites by examining depressive symptoms, overall stress, resilience, and coping, utilizing the Transactional Model of Stress and Coping. Of the 207 individuals participating in this study, 109 identified as American Indian/Alaska Native and 98 as non-Hispanic white. Despite demographic similarities, American Indian/Alaska Natives exhibited more stressors related to COVID-19 as well as higher depressive symptom scores compared to non-Hispanic whites. Furthermore, COVID-19 stressors were more positively correlated with depressive symptoms for American Indian/Alaska Natives than non-Hispanic whites. For American Indian/Alaska Natives, the predominant coping processes identified were planful problem solving, escape-avoidance, and self-controlling. This study provides data to support programs and policies centered on improving the psychosocial health for American Indians/Alaska Natives and decreasing COVID-19-related health disparities.
Avaliação das características físicas do solo da área da mata da galeria na sub-bacia hidrográfica da Mariana para a conservação ambiental

Published: April 2021

O objectivo deste trabalho era caracterizar as propriedades físicas do solo da área da mata da galeria na sub-bacia hidrográfica da Mariana. Os atributos físicos avaliados foram: densidade aparente, humidade gravimétrica, porosidade do solo e resistência mecânica à penetração. O trabalho de campo foi levado a cabo em Alta Floresta-MT, Brasil. Nove parcelas de 20 m x 50 m de superfície foram marcadas ao longo das zonas do curso superior e médio do rio de tal forma que eram representativas de toda a extensão da sub-bacia hidrográfica. O desenho experimental foi completamente aleatório. A densidade do solo da área da mata de galeria era superior à da floresta nativa, de modo a que o desenvolvimento do sistema radicular das árvores pudesse mesmo ser restringido. Verificou-se que a humidade gravimétrica era homogénea quando diferentes áreas ou diferentes profundidades eram comparadas.

Published: April 2021

Missing teeth can be substituted by the use of the dental implants. This treatment modality has been proven to be a gold standard for replacement of the missing tooth in the past decade. The most widely used implants in the current scenario are the osseointegrated implants with various shortcomings and the most prominent one is the lack of the periodontal ligament. To overcome this, implants with periodontal ligaments can be procured and this can be possible by the application of the tissue engineering concept along with suitable implant material. Tissue engineering has become an integral part of the periodontal therapy and its use has opened various gates in the field of dentistry. A tissue engineered periodontal ligament around the dental implant has been introduced in the past few years and is called as ligaplant. These ligaplants has become a promising option that can provide good biological performance leading to an increased life of the prosthesis. This review article highlights the advantages of the periodontal ligament combined dental implants in comparison to the conventional implants and also the process of their procurement has been discussed.

The work deals with the study of the influence of humic preparation ‟BIO-Don” on indicators of soil fertility, the enzymatic activity of Сalcic Chernozem (Pachic) at the experimental site, as well as on the productivity and quality of fruit crops, for example, cherries varieties Talisman and Vasilisa in terms of work experience in the open ground in the territory of «Agrofirm “the Red garden”». Treatment of fruit trees was carried out once by drip irrigation in a dosage of 300 l/ha of working solution with a concentration of gp 0.008 g/l for carbon, soil samples were taken before treatment, two weeks and a month after the application of the humic preparation, a site without the use of “BIO-Don” was used as a control option. The treatment of plants with a humic preparation increases the activity of the enzymes catalase, invertase and phosphatase, especially during the period of mass ripening of fruits. Accordingly, at the same time, the content of mobile phosphorus and exchangeable potassium decreases, which is due to the increased removal of these elements by plants. Chemical analysis of fruit products for the content of soluble solids and titrated acidity revealed a statistically significant increase in these indicators in fruits from areas treated with humic preparation, which is manifested by their greater taste saturation.

The Compatibility between Fibonacci Sequence and Elliott Impulse Wave in the Context of A-share Market
Authors: Sang Yufeng
Published: April 2021

The connections between Fibonacci sequence and Elliott impulse wave that Ralph Elliot has proposed in Elliott Wave Principle are not valid all the time owing to the type and variability of the stock market. It is a probabilistic event which can reflect the compatibility between Fibonacci sequence and Elliott impulse wave. In order to explore the compatibility between Fibonacci sequence and basic-form Elliott impulse wave in the context of Chinese A-share market, a research via analyzing the historical trend of 50 core assets’ individual stocks was conducted in Chinese A-share market. The study reveals that Fibonacci sequence does not highly fit basic-form Elliott impulse wave in the context of Chinese A-share market. Suggestions for investors are diversifying the investment strategy to enhance risk controllability, rather than using Elliott Wave Principle singly.

Published: April 2021

Relational Frame Theory (RFT) is the simplest form of operant theory since it claims nothing more than a particular type of behavior, arbitrarily applicable derived relational responding, is an operant. While the theory is simple, its implications are not, and adoption has been slow until recently. RFT was first formally described in 1985 and in the 35 years since, hundreds of studies have been conducted on relational learning from an operant point of view. The present paper briefly summarizes that history and examines some of its key claims. So far, the empirical program delineated by RFT has held up remarkably well. Future directions are delineated that will enable a more comprehensive evaluation of the importance of the RFT research program, and a more thorough exploration of its profound implications.
