Concept of artisan chocolate from the perspective of chocolatiers
Authors: Seçuk Berkay , Seçim Yılmaz
Published: August 2023

Artisan chocolate is the name given to chocolate products made with reference to the traditional production process, which is followed and consumed with interest by many consumers today. The study aims to determine the framework of the concept of artisan chocolate with the aspects of professionals working on chocolate and to evaluate the chocolate production processes in terms of artisan applications. In the study that used the focus group interview method, interviews were conducted with experts in the field of artisan chocolate in different countries. The obtained data were analysed by a descriptive analysis method. As a result of the evaluations, five different themes were emerged. These include ‘Artisan Chocolate: A Passion Story’, ‘Chocolate Types and Quality in Artisan Production’, ‘Chocolate and Health’, ‘Professional Development and Change in Artisan Chocolate’ and ‘Future of Artisan Chocolate’. In light of these findings, the conceptual framework of artisan chocolate has been expanded and a new definition has been made. Participants generally associated the concept of artisan chocolate with passion, high quality, art and happiness. Tablets, bonbons, pralines, truffles and bark chocolates produced by artisan chocolatiers are considered healthful, contingent upon their cocoa ratio. Considering the study data, it is understood that artisan chocolate-making is valuable for sustainable cocoa farming. It is thought that the consumption of artisan chocolate will increase with the expanding interest in fair food, quality and naturalness in the future.
‘Butchered Voices’: Haunted memories in the work of The Caretaker
Authors: Lesser Clare
Published: August 2023

Describing his early compositional processes as ‘butchering’ in conversation with Simon Reynolds, the songs and voices that James Leyland Kirby, also known as The Caretaker amongst other aliases, has obsessively reworked, looped, stretched and otherwise deconstructed, appear as ghosts, eternally trapped in auditory labyrinths of melancholy decay; the sonic equivalent of stirring bottomless pools of murky water. Drawing on conceptions of hauntology from the work of Jacques Derrida (1930–2004), Mark Fisher (1968–2017) and others, this article will explore The Caretaker’s use of ‘butchered’ voices in The Haunted Ballroom Trilogy and Patience (After Sebald), to explore the deconstructive labyrinths that are intrinsic to his work in Selected Memories from the Haunted Ballroom (1991) onwards.

The permanent mandibular first molar is frequently involved in conventional root canal treatment due to its function and position in the oral cavity. Additional root canals mandate accurate diagnosis and conservative management to prevent any procedural errors. The first independent middle mesial canal incidence was verified in mandibular molars in 1974, with a global incidence of 10.8–27.0%. Reporting of the middle distal canal in the endodontic literature is scarce, with an incidence of 0.2–3%. The present case report describes the endodontic management of an unusual permanent mandibular first molar with three canals in the mesial and distal roots, diagnosed with irreversible pulpitis and apical periodontitis. A dental operating microscope and multiple angulated radiographs were used to identify the unusual morphology, and this was confirmed with cone-beam computed tomography imaging. The access cavity was modified to a trapezoidal shape, and the pulp chamber was carefully explored following root dentinal maps to expose additional canals by ultrasonic troughing. Incorporating a dental operating microscope and cone-beam computed tomography imaging in routine endodontic cases facilitates a better understanding and visualization of the complex root canal anatomy, making even the management of endodontically challenging cases more predictable.

Objective: To compare of pharyngeal airway dimensions and dentoskeletal changes after treatment with twin block (TWB) and monoblock (MB) appliance in growing patients. Methods: The sample was comprised of a total of 72 patients at the ages of 10 to 13. The TWB group consisted of 36 patients (22 females, 14 males, mean age: 11.9±1.5) and MB group consisted of 36 patients (18 females, 18 males, mean age: 11.8±1.2). The linear and angular measurements were evaluated on lateral cephalometric radiographs at beginning (T0) and end of treatment (T1). Results: The amounts of increase in the inferior airway space, L1xNB, IMPA and FMA measurements from T0 to T1 in the TWB group were significantly higher (p < 0.05).In the TWB group, the amounts of the increase in the soft palate thickness, distance between hyoid and C3, Co-A and Co-Gn measurements from T0 to T1 in the female patients were significantly higher (p < 0.05).In the MB group, the amounts of increase in the Upper adenoid thickness and Vertical airway length measurements from T0 to T1 in the female patients were significantly higher (p < 0.05). Conclusion: Both the MB and TWB appliances increase the pharyngeal airway dimensions, and the lower airway is most affected by the appliance type. The effects of the MB and TWB appliances on tongue dimensions and hyoid bone movements are different.

Ramsay Hunt syndrome (RHS) is a disease that is caused by the varicella-zoster virus and is characterized by severe ear pain, auricular vesicular eruptions, and peripheral facial paralysis. Objective: The aim of this case report is to provide information about the clinical findings and treatment process of RHS, which is a rare case and may have oral findings and stress the importance of early diagnosis. Case Report: A 60-year-old male patient had previously consulted an otolaryngologist and a family physician with complaints of vesicular eruptions in the right ear auricle and on the mandible. The patient in whom a diagnosis could not be established presented to the Department of Oral and Maxillofacial Radiology after exacerbated lesions. White plaque-like and ruptured vesicular lesions were observed in the intraoral examination. All vesicular lesions were on one side of the face, and the patient was referred to the dermatology clinic with the diagnosis of RHS. Facial paralysis fully recovered in a short time after early diagnosis and treatment. It should be kept in mind that there may also be oral findings in RHS, and a patient’s intraoral and extraoral examination findings should be evaluated together. Conclusion: Early diagnosis and treatment are highly important in preventing complications such as permanent facial paralysis, vestibulocochlear dysfunction, and hearing loss

Fenestration term is derived from the Latin word ‘fenestra’ means ‘window’. Gingival fenestration is not found in routine while its actual occurrence is assumed to be higher. Additionally, if these mucogingival defects persist for a longer duration it may lead to adverse outcomes like compromised esthetics, hypersensitivity, plaque and calculus deposition, and susceptibility to dental caries. Present cases of gingival fenestration were successfully treated by using full-thickness flap elevation with connective tissue graft placement. Two cases were presented with the accumulation of plaque and calculus and having gingival fenestration to the respective sites. After phase 1 therapy, full thickness flap was raised and a connective tissue graft was placed beneath the fenestrated area. The successful results were obtained in both cases in terms of complete closure of gingival fenestration defects and well-adapted margins with adjacent tissues at one year of follow-up. Full thickness flap with connective tissue graft procedure resulted in complete closure of gingival fenestration in both cases with no recurrence at one-year follow-up and can be used as a successful and predictable treatment modality for the management of such cases.

Objective: This study aimed to evaluate the first endodontic case experiences, self-confidence levels, and perceptions toward endodontic learning of final-year undergraduate students. Methods: An online questionnaire was emailed to 270 final-year dental students at 10 Malaysian dental schools. The questionnaire consists of 29 questions on students’ experience, self-confidence, and perception toward endodontic learning. Results: The response rate was 74.4%. The most frequently treated case was tooth diagnosed as nonvital associated with periapical periodontitis. Most of the students perceived working length determination as the most difficult stage and reported having low confidence in locating canal orifices in multirooted teeth and achieving satisfactory obturation. Overall, the students were satisfied with the endodontic knowledge taught by their respective faculties. Conclusion: Endodontic teaching in Malaysian dental schools was perceived as satisfactory by most dental students. Although endodontic treatment is perceived as difficult, students demonstrated high confidence in carrying out this treatment. However, they had limited ability in treating the complex root canal system.

Published: August 2023

The use of natural polysaccharides in stretchable hydrogels has attracted more and more attention. However, pure polyvinyl alcohol (PVA) hydrogel has poor mechanical properties and low sensitivity in strain sensors. Composite hydrogels with high tensile properties (the storage modulus of 6,397.8 Pa and the loss modulus of 3,283.9 Pa) and high electrical conductivity (1.57 S·m−1) were prepared using a simple method. The Fe-vermiculite and lignocellulosic nanofibril-based hydrogels were applied as reliable and stable strain sensors that are responsive to environmental stimuli. The prepared hydrogels exhibited excellent ionic conductivity, which satisfied the needs of wrist flexion activity monitoring. The results showed that the PVA/LF0.4 hydrogel has a natural formulation, high mechanical strength, and electrical conductivity, which has great potential for application in artificial electronics.

Die Leuenberger Konkordie wird im Kontext anglikanischer ökumenischer Abkommen, insbesondere in Europa, betrachtet. Anglikaner haben mit mehreren GEKE-Mitgliedskirchen ähnliche Vereinbarungen wie Leuenberg getroffen, die allerdings keine Kirchengemeinschaft begründen und keine Austauschbarkeit der Ämter ermöglichen. Die Gemeinsame Erklärung von Porvoo konnte aufgrund einer Einigung über das Bischofsamt die Kirchgemeinschaft erreichen. Auch die Vereinbarung zwischen der Church of Ireland und der Methodist Church in Ireland führte zur Kirchengemeinschaft.

Authors: Li Gang , Xiao Haiping , Liang Luntao , He Xiangyu , Qi Nana
Published: August 2023

The effect of cationic surfactants on the growth of gypsum was evaluated under conditions of a simulated production process of gypsum desulfurization. We used a laser particle size analyzer and a microscope to determine the particle size and morphology. The growth rate of gypsum was determined by the equation for the rate of chemical reaction of CaSO4·2H2O. The results showed that the growth rate at a supersaturation ratio of 2.4 increased by 50% with 30 mg/L of a dodecyldimethylbenzylammonium chloride. The gypsum morphology changed from needle-like in the absence of additives to tabular in the presence of cationic surfactants, indicating that relatively thicker and larger crystals were formed. Finally, the investigated cationic surfactants were beneficial to the normal operation of the desulfurization process.

A COVID-19, doença infecciosa causada pelo SARS-CoV-2, caracteriza-se como uma infecção respiratória aguda que afeta de forma direta o sistema respiratório humano e que apresenta alto grau de transmissibilidade. Apesar de se tratar de uma doença que interfere primordialmente aspectos relacionados ao sistema respiratório, estudos vêm demonstrando influência direta desta enfermidade em complicações cardíacas tais como miocardite, insuficiência cardíaca, arritmias e lesão cardíaca aguda. Nesse trabalho, um modelo matemático do sistema cardiovascular incluindo a circulação sistêmica e pulmonar é estudado tendo em vista a avaliação dos impactos da COVID-19 no sistema cardíaco. Os efeitos da COVID-19 são introduzidos no modelo através da alteração de parâmetros fisiológicos com o intuito de representar os efeitos da doença. Simulações computacionais foram realizadas em um caso normal e um caso patológico para se avaliar e verificar os efeitos da COVID-19 em quantidades de interesse fisiológicas do sistema cardiovascular.
Development of a Concept Inventory on Open and Transparent Research Practices
Authors: Markant Douglas B. , Galati Alexia
Published: August 2023

Over the past decade psychology researchers have begun adopting practices that promote openness and transparency. While these practices are increasingly reflected in undergraduate psychology curricula, pedagogical research has not systematically examined whether instruction on open science practices improves students’ conceptual understanding of research methods. We developed the Open Science Concept Inventory (OSCI) to evaluate the impact of integrating open science practices into research methods courses. First, we created a set of hypothetical dilemmas related to a range of open science concepts and elicited open-ended responses from undergraduates (N = 64, Study 1). Based on the responses, we created a 40-item multiple-choice questionnaire, which we administered to a new group of participants (N = 262, Study 2) and used item response theory to select 33 items for the final OSCI. Finally, in two implementation rounds across two semesters (Study 3, total N = 37), we evaluated students’ learning gains with the OSCI in a pre-test/post-test design. The implementation rounds involved new materials on open science for a psychology research methods course, including video lectures that situated questionable research practices in the current norms of science and introduced emerging solutions. After excluding extremely fast survey responders, an exploratory analysis showed learning gains among students who expended appropriate effort when completing the OSCI. By systematically evaluating a tool that is easily integrated into existing curricula, we aim to facilitate the adoption of open science practices in undergraduate instruction and the assessment of students’ conceptual foundations for conducting robust and transparent research.

Bifurcated anatomical locations in the arterial tree, such as coronary artery bifurcations, are prone to develop obstructive atherosclerotic lesions due to the pro-atherogenic low wall shear stress. The percutaneous treatment of bifurcation lesions is among the most challenging complex coronary interventions, including different multistep stenting strategies. Even though provisional side branch (SB) stenting is recommended as the primary approach in most cases, the debate continues between provisional SB and upfront two-stent strategies, particularly in complex bifurcations consisting of a significantly diseased SB that supplies a crucial myocardial territory. This review will highlight the importance of understanding the bifurcation philosophy and provide an individual algorithmic approach to find the optimal treatment strategy for each patient with a non-left main coronary bifurcation lesion. Considering the most recent scientific evidence, the advantages and disadvantages of each stenting technique and the role of intracoronary imaging to optimize bifurcation percutaneous coronary intervention outcomes will be discussed.

Modern methods of vaccination have confirmed their high effectiveness in fighting against the pandemic of a novel coronavirus infection. However, the use of various types of vaccines requires studying the effectiveness of the post-vaccination immune response (PIO), first of all, assessing the specificity and amount of production of antibodies to the surface and internal antigens of the SARS-CoV-2 virus, in particular, after the use of the most promising domestic vaccine Gam-Covid-Vac (Sputnik V). In particular, the data on the effectiveness of PVIR (increased antibody level) for the most promising domestic vaccine Gam-Covid-Vac (Sputnik V) need to be confirmed. It is also necessary to evaluate the effectiveness of the laboratory methods used for this purpose. To assess the effectiveness of PVIR, samples of biomaterial (blood serum) obtained on the 2225 day after inoculation of the second component of the vaccine from 202 Sputnik V-vaccinated, not preimmunized subjects, lacking antibodies to SARS-CoV-2 before vaccination, were examined. The levels of IgG and IgM antibodies to the surface and nucleocapsid antigens of the SARS-CoV-2 virus were determined using several semi-quantitative and quantitative methods and reagent kits from national and foreign manufacturers. To assess the diagnostic effectiveness of the methods, a comparative analysis of the specificity and sensitivity of all the laboratory methods used and a data correlation for various quantitative methods (using the Spearman correlation coefficient) between antibodies specific to the full-sized trimerized S-protein and the receptor-binding domain (RBD) of the SARS-CoV-2 S-protein were carried out. During the study, it was determined that all the reagent kits used to study IgG antibodies against SARS-CoV-2 S-protein and S-protein RBD showed maximum (100%) specificity in in the majority subjects (from 186 to 202 samples). The relevance of the data (comparative specificity), both for semi-quantitative and quantitative ELISA as well as for both ILA test systems regarding qualitative characteristics (positivenegative) was also close to the maximum magnitude (98.499.4%). A post-vaccination immune response during Sputnik V vaccination analyzing production of specific IgG antibodies was observed in 98.9% of all vaccinated subjects. IgG antibody range was studied to assess related protective level. Data are presented that a protective level of more than 150 BAU/мл was observed in 59.390.5% of the subjects, above 500 BAU/ml in 22.052.4% of the subjects, depending on the method used and the set of reagents. Based on the data obtained, it is concluded that all the methods and kits of reagents used, including domestically manufactured semi-quantitative tests, can be considered adequate to assess effectiveness of the post-vaccination immune response analyzing production of SARS-CoV-2-specific antibodies.
Impacto observado das mudanças climáticas nos rios brasileiros
Authors: Cortizo Sérgio
Published: August 2023

As séries históricas de vazões naturais afluentes dos principais rios brasileiros, publicadas anualmente pelo Operador Nacional do Sistema Elétrico (ONS), apresentam claros padrões regionais de variação de longo prazo desde o ano 1931. Como estas vazões resultam do balanço hídrico na bacia hidrográfica a montante de cada posto de medição, é possível determinar as causas destes padrões regionais de longo prazo: alterações significativas na cobertura vegetal (tipicamente desmatamento) e mudanças climáticas (principalmente nas precipitações e temperaturas médias). Em grande parte do território nacional, englobando aproximadamente as regiões NE, SE e Sul, as variações de longo prazo das vazões médias nas últimas quatro décadas foram devidas principalmente às mudanças climáticas associadas ao aquecimento global antrópico. Como estas mudanças nos parâmetros climáticos persistirão, pelo menos nos próximos vinte anos, o diagnóstico hidrológico das variações de longo prazo permite elaborar projeções confiáveis paras as vazões futuras nas próximas duas décadas, com uma margem de erro menor do que os métodos indiretos, baseados na regionalização (“downscaling”) de modelos globais de clima (GCMs).
Role of dd-cfDNA in Detection of Subclinical Rejection in Pediatric Kidney Transplant Recipients
Authors: R Mendel , C Benchimol , X Wu
Published: August 2023

Background: Detection of subclinical rejections has been a real challenge for pediatric nephrology. We hypothesized that donor-derived cell-free DNA (dd-cfDNA) in combination with serum creatinine levels and a kidney biopsy provide a “gold-standard” for clinicians so that treatment for subclinical rejection can be initiated appropriately. Design/Methods: We performed a two-year cohort study on total (n=5) pediatric patients aged 5-19 years who received kidney transplant within 2015-2019. Blood was collected for dd-cfDNA, i.e., AlloSure, at the time of scheduled surveillance visits or when clinically indicated. During the study period, serum creatinine and tacrolimus were measured as well. For diagnosing subclinical rejection, dd-cfDNA was divided into 3 groups: low dd-cfDNA <0.5%, high dd-cfDNA 0.5%-1%, very high dd-cfDNA>1%. A kidney biopsy was performed in one patient who had very high dd-cfDNA 2.3% (nl<0.2%), high serum creatinine (sCr 1.17 mg/dL, baseline 0.5 mg/dL), in the absence of tacrolimus levels. Kidney biopsy revealed acute cellular rejection (ACR) type 1A. Patient received intravenous immune globulin (IVIG) 2 g/kg x 1, IV pulses with methylprednisolone 20 mg/kg/dose x 3, followed by a steroid taper over one month. Her serum creatinine remains normal since. Whereas in the other 4 patients, dd-cfDNA did not show significant change, no subclinical rejection was observed. Conclusion: dd-cfDNA in combination with serum creatinine levels and a kidney biopsy can be considered the “gold standard” which improves early diagnostic utility for subclinical rejection.

Published: August 2023

La biodiversidad es de gran importancia para los seres humanos porque gran parte de los beneficios que obtenemos de los ecosistemas dependen de la presencia, abundancia e interacciones de los seres vivos que los componen. El deterioro sin precedentes de la biodiversidad y las problemáticas ambientales derivadas de su alarmante y acelerada pérdida hacen que este constructo transversal cobre relevancia tanto para el ámbito científico como el educativo, especialmente en la formación docente. Desde una perspectiva didáctica y enfocados en las prácticas pedagógicas, reconocemos que las estrategias de enseñanza de la biodiversidad ponen en acción los saberes del profesorado para mediar con los procesos de aprendizaje de sus estudiantes. Por ello, el objetivo de este trabajo es recopilar y sintetizar investigaciones que desarrollen estrategias para la enseñanza de la biodiversidad desde el conocimiento científico convencional con docentes en ejercicio y en formación inicial en Latinoamérica (entre los años 2004 y 2020). Las tendencias y puntos críticos de los hallazgos indican una abundancia de estudios en la región, con predominancia de contribuciones provenientes de Brasil, Colombia y Argentina, y una ligera mayoría de los llevados a cabo con docentes en formación inicial. Finalmente, aportamos algunas conclusiones e implicancias para la formación docente, las prácticas de enseñanza y la investigación educativa.

Published: August 2023

English is one of the top ten international languages spoken by people globally and it has continued to play a dominant role in various fields and sectors. Despite the importance of English, it has been a subject of political and social debate in the South Africa space. Nevertheless, irrespective of arguments for and against it, English remains an indispensable language to learn and understand for any globally oriented people, institution, and country. Attitude towards a foreign language learning are part of factors that influence success or otherwise in such a language learning process. Thus, this study aims to investigate the attitude of ECP students towards English and English language learning. The study further explores the differences in the attitudes of ECP students by gender. The participants of the study were a sample of 98 students who were selected through a simple random sampling of students from two different academic years of the ECP in the Faculty of Management and Commerce. Descriptive and inferential analytical techniques were applied on information obtained through a closed-ended questionnaire. The study found that respondents have a positive attitude towards English and English Learning. Therefore, this study concludes that social and political debates on language policies in higher institutions of learning should not be done outside the perception and realities of direct receivers of socio-political debate outcomes. Furthermore, strategies to enhance the English language skills of the students in the midst of the eleven recognized national languages that cannot be absolutely accommodated in the South African higher institutions of learning should be continually developed.

Refusal refers to a face-threatening act (FTA) for it can risk one’s face in communication. It encompasses turning down someone’s request, offer or suggestion. The speech act of refusal has been one of the most prominent areas of interest for many scholars. However, there is a dearth of such study in Malaysia, particularly within the Malay community. Aimed to fill the gap, this study examined the refusal strategies used in English by Malay ESL undergraduates, observe the differences and similarities in the refusal strategies of male and female undergraduates, and analyse whether relative power has an influence on the choice of their refusal strategies. This study employed the Discourse Completion Test (DCT) which was distributed among sixty Malay ESL undergraduates, consisting of 30 males and 30 females where they were required to refuse requests from three addressees (lecturer, friend, junior) in five different situations. The collected data were then analysed quantitatively. The findings showed that 32 out of 41 types of refusal strategies were used by the participants. Both male and female students employed more indirect refusal strategies regardless of the person’s relative power. Furthermore, relative power did influence the participants' choices in refusal strategies.

The article is devoted to the motion analysis of a highly maneuverable mobile robot with four omniwheels, taking into account the conditions for the appearance of wheel detachment from the surface, and the occurrence of wheel slipping. Within the motion analysis the task of determination support reactions for a mobile robot is considered. To solve this task, the design of a mobile robot is presented in the form of the frame with rods. To disclosure the static indeterminacy of the considered system the forces method is used. Dependences of support reactions from the position of the center mass are obtained. The feature of the considered system is that the obtained dependencies of the support reactions are nonlinear. Based on the obtained dependences of the support reactions, the influence of the position of the center of mass of a mobile robot with four wheels on the occurrence of detachment and slipping of wheels of a mobile robot was considered. Investigation was carried out within the framework of the dry friction model, according to which module of the friction force proportionally depends on the support reaction acting on the wheel from the side of the motion surface. Simulation was carried out, as a result of which the conditions for the position of the center of mass of a mobile robot were determined, in which wheels of a mobile robot do not detach from the motion surface, and there is no wheel slipping.
