Published: October 2022

W artykule przedstawiono wyniki badań par ciernych hamulca tarczowego z klockami: klasycznymi i typu ceramicznego. Badania wykonywano ze względu na zużycie elementów par ciernych oraz ze względu na emisję pyłów związanych ze zużyciem par ciernych. Badania empiryczne wykonano na stanowisku do badań właściwości ciernych okładzin hamulcowych. Do pomiarów imisji4 frakcji wymiarowych cząstek stałych zastosowano pyłomierz. Wykonywano również pomiary temperatury powierzchni ciernej z zastosowaniem kamery. Badania wykonywano w trzech seriach (docierania i dwóch seriach badań par dotartych) z cyklami pracy obejmującymi hamowanie z przerwami, sterowanymi m.in. przez temperaturę powierzchni ciernej. Względna różnica zużycia, oceniana na podstawie grubości pary ciernej, była dla klocków typu ceramicznego mniejsza o prawie 40%, a na podstawie masy – większe niż 25%. Stwierdzono, że w pyle rozproszonym w powietrzu pomieszczenia pomiarowego dominująca była frakcja cząstek stałych PM1 – o wymiarach charakterystycznych mniejszych od 1 μm. Względna różnica imisji cząstek stałych okazała się rzędu 50% w wypadku zastosowania klocków typu ceramicznego. Zastosowanie różnych rodzajów klocków hamulcowych nie miało znaczącego wpływu na temperaturę pary ciernej. Ogólnie stwierdzono, że zastosowanie materiału typu ceramicznego na klocki hamulcowe ma wymierny wpływ na poprawę właściwości trybologicznych pary ciernej hamulca tarczowego.
An analysis of collision avoidance manoeuvres in emergency traffic situations
Authors: Jurecki Rafał 
Published: October 2022

This paper provides an overview of the research into the driver behaviour in simulated near collision situations. The aim of such investigations is to determine various parameters characterising the driver performance, e.g. driver response time. The driver response time is a very important parameter used, for example, to analyse road accidents. The results presented in this paper come from a study performed for two different emergency traffic situations using some predefined procedures (scenarios). The tests included situations in which a person driving a subject vehicle on a test track was to respond to obstacle mock-ups on a conflicting path (intrusion of a pedestrian from the left or from the right and intrusion of a vehicle from the right). The test data was used to determine the parameters describing the driver behaviour, i.e. the braking response time (braking manoeuvre), the steering response time (steering manoeuvre) and the intensity of the two manoeuvres. This paper compares the values of the driver response time for two scenarios, each with two variants. The average values of the braking response time and the steering response time were determined on a closed track in relation to the Time-To-Collision (TTC) in the range 0,6÷3s, characterising a near collision situation. Another parameter describing the driver behaviour discussed in this paper is the intensity of an avoidance manoeuvre. In the case of braking, the relative brake pedal displacement was analysed, while in the steering manoeuvre, the steering angle was taken into account. The average values of the braking displacement and the steering angle were presented in the function of the TTC. This paper looks at the relationship between the intensity of the driver response (braking, steering), the driver response time and the TTC.
Más allá del cambio metodológico en la práctica clínica: Evaluación de las pruebas de factor de crecimiento insulínico tipo 1
Authors: Sienes Bailo Paula , Fabre Estremera Marta , Cuenca Alcocel José , César Márquez María Ángeles 
Published: October 2022

Resumen

Objetivos
El factor de crecimiento insulínico tipo 1 (IGF-I) es el biomarcador más ampliamente utilizado para el diagnóstico y seguimiento de los trastornos relacionados con el crecimiento, aunque su cuantificación en suero implica una serie de dificultades. De este modo, se han observado discrepancias en las concentraciones de IGF-I según el tipo de ensayo empleado, especialmente en el contexto de concentraciones superiores o inferiores al rango de normalidad.

Métodos
Entre noviembre y diciembre de 2020, se realizó un estudio prospectivo en un hospital universitario de tercer nivel, en el que se analizaron 212 muestras séricas para determinar la calidad analítica de la prueba de IGF-I cuando se realiza en el analizador Cobas e411 (Roche Diagnostics) y compararla con la de Immulite 2000XPi (Siemens).

Resultados
El presente es el primer estudio en aportar evidencia sobre la existencia de discrepancias en las concentraciones de IGF-I, según sean medidas con Immulite 2000XPi o Cobas e411. En el análisis de regresión de Deming se obtuvo una pendiente de 1,570 (95% CI: 1,395–1,745), una ordenada en el origen de −58,591 (IC 95%: −89,151 to −28,030), con un R2=0,967 y un sesgo medio de +53,061, con una sobreestimación de los niveles de IGF-I. Observamos que con Cobas e411 se obtienen concentraciones de IGF-I anormalmente elevadas, aunque son necesarios más estudios para dilucidar la causa de dichas discrepancias.

Conclusiones
Los resultados de este estudio pueden ser de utilidad para alertar a los facultativos, así como a los profesionales de laboratorio de dicha circunstancia, con el fin de evitar la interpretación errónea de niveles aumentados de IGF-I como un fracaso terapéutico en lugar de como un problema asociado a este cambio de método analítico.
Spectral collocation method approach to thermal stability of MHD reactive squeezed fluid flow through a channel
Authors: Titiloye Emmanuel O. , Adeosun Adeshina T. , Ukaegbu Joel C. 
Published: October 2022

Abstract
The current study focuses on the thermal stability of exothermic MHD reactive squeezed fluid flow between parallel plates. The problem’s governing nonlinear partial differential equations are transformed into dimensionless ones. The dimensionless equations obtained are highly nonlinear and are then numerically solved using the spectral collocation method (SCM). The acquired results are verified using Runge–Kutta fourth-fifth order (RK45) combined with shooting method, and a good agreement is achieved. Some graphs and tables are provided to examine the exothermic combustion process by focusing on the effects of emergent kinetic parameters such as activation energy, heat generation, and squeezed flow on the temperature profile and thermal stability of the system. It is discovered that the activation energy parameter tends to minimize the temperature profile while also improving the system’s thermal stability. However, the squeezed parameter and the heat generation rate parameter increase exothermic chemical reactions, causing the system to become unstable.
Everyday heritaging: Sino-Muslim literacy adaptation and alienation
Authors: Bhatt Ibrar , Wang Heng 
Published: October 2022

Abstract
What we in this article describe as “Sino-Muslim heritage literacies” have existed in China for as long as there have been Muslims in the region (since the 7th century according to the best evidence). The community’s religious and heritage literacy practices can incorporate a systematic Arabic representation of Chinese, systems of Chinese characters representing Arabic pronunciation, and more contemporary digitalised manifestations of heritage literacy in everyday life. Using a social practice approach to literacy, this paper reports on multi-generational interviews, artefact collection, and ethnographic observations with two families in Xi’an (Shaanxi, China) to explore how heritage literacy practices maintain a presence in Sino-Muslim life through traditional systems of community and religious education and contemporary social and material networks. We discuss what these empirical cases reveal about literacies in Sino-Muslim religious life, with respect to how heritage is adapted or diminished across generations. We also argue that it is crucial to situate Sino-Muslim heritage literacy in spaces beyond rigid and state-defined ethnic and religious discourses which tend to confine the identity of Sino-Muslims into officially designated categories. Doing so, we contend, has useful theoretical and methodological import, and can shed light on inquiry about heritage literacy in other minority settings.

Published: October 2022

Abstract

Objectives
Thyroid liposarcoma is a rare tumor. Its low prevalence accounts for the scarcity of data in the literature, which consists mostly of small studies and case reports.

Case presentation
We present the case of a 60 years old male with no past medical or past surgical history and presented with neck discomfort and a large left thyroid nodule. Thyroid ultrasound and CT scan were performed and confirmed the existence of a thyroid nodule most probably inside the left inferior thyroid lobe. In the posterior mediastinum, two fatty formations were found. To complete, an MRI was performed, showing a mixed lesion, of the lower neck and upper chest. The patient underwent an extended resection which consisted of an en bloc resection of the lesion (left thyroid lobectomy and isthmus resection) by an anterior transverse cervical incision and a sternotomy. Tracheal and laryngeal shaving and esophageal shaving with resection of the esophageal muscularis was performed as well. The pathological evaluation of the specimen showed a grade II dedifferentiated liposarcoma with an inflammatory component.

Conclusions
Thyroid liposarcoma is a rare lesion of the thyroid. Its management requires an exhaustive workup followed by an en bloc resection of the lesion. Depending on the histology, postoperative radiation therapy may or may not be necessary.
Phonetic change over the career: a case study
Authors: Riverin-Coutlée Josiane , Harrington Jonathan 
Published: October 2022

AbstractThis study is concerned with phonetic flexibility in adulthood. Through a longitudinal analysis of the speech of the public French speaker Michaëlle Jean, we explore the relationship between an individual’s phonetic characteristics and career path. We carried out an acoustic analysis of the contextual tense-lax split of the high vowels /i y u/, a phonetic feature of Quebec French that is not found in other French-speaking areas. Sixty-two recordings spanning three decades and divided into five different stages of the speaker’s career were considered. The results showed that Jean produced the tense-lax split as a journalist based in Quebec, but progressively suppressed it as her career became more international, after which a reversal of the trend was observed. Taken together, these results indicate that a certain phonetic flexibility is maintained over the lifespan, and that career is an influential external factor that could be more frequently considered in sociolinguistic studies. From a broader perspective, our study contributes to a better understanding of language use during social ageing, which has proven to be less linear than chronological ageing.

Effect of nano Al2O3 particles on the mechanical and wear properties of Al/Al2O3 composites manufactured via ARB
Authors: Gao Yuanfei , Vini Mohammad Heydari , Daneshmand Saeed 
Published: October 2022

Abstract
This study first tried to fabricate AA1060/Al2O3 composites via the stir casting and accumulative roll bonding process. Then, the effect of nano Al2O3 Vol% on mechanical, wear, and microstructural properties of these kinds of composites have been investigated. An excellent particle distribution through the aluminum matrix has been achieved after the fourth cycle. Then, mechanical properties, wear resistance, and microstructural properties have been investigated. The results showed that the strength of these composites was enhanced and the elongation of samples decreased by higher alumina Vol% contents. Also, there is a significant increase in wear resistance by increasing alumina content in the Al matrix through the stir casting process.

Prefrontal Cortical to Mediodorsal Thalamus Projection Neurons Regulate Posterror Adaptive Control of Behavior
Authors: Bruinsma Bastiaan , Pattij Tommy , Mansvelder Huibert D. 
Published: October 2022

AbstractAdaptive control is the online adjustment of behavior to guide and optimize responses after errors or conflict. The neural circuits involved in monitoring and adapting behavioral performance following error are poorly understood. The prefrontal cortex (PFC) plays a critical role in this form of control. However, these brain areas are densely connected with many other regions, and it is unknown which projections are critical for adaptive behavior. Here, we tested the involvement of four distinct dorsal and ventral prefrontal cortical projections to striatal and thalamic target areas in adaptive control. We re-analyzed data from published experiments, using trial-by-trial analyses of behavior in an operant task for attention and impulsivity. We find that male rats slow their responses and perform worse following errors. Moreover, by combining retrograde labeling and chemogenetic silencing, we find that dorsomedial prefrontal pyramidal neurons that project to the lateral nucleus of the mediodorsal thalamus (MDL) are involved in posterror performance and timing of responses, specifically with unpredictable delays until stimulus presentation. Together, these data show that dorsal medial PFC (mPFC) projection neurons targeting the lateral MDT regulate adaptive control to flexibly optimize behavioral responses in goal-directed behavior.
Studi Kelayakan Kompetensi Profesional Guru Di Madrasah Ibtidaiyah Nurul Hikmah Sukajati Haurgeulis Tahun 2019

Published: October 2022

Teacher competence is very important, so a teacher must have the ability to professionally improve the implementation of his duties in the field of education. It is useful for educating the nation's children. This feasibility study aims to formulate policies related to the quality of education improvement that is focused on the condition of proper madrasah ibtidaiyah (MI) teachers based on the professional competencies possessed by each teacher. This study uses a qualitative method with a cross sectional technique to analyze the data of each MI teacher based on academic qualifications according to the field of study he teaches. The findings of this study indicate that there are still many MI teachers who do not have undergraduate academic qualifications as stipulated in Law No. 14 of 2005 concerning Teachers and Lecturers. The ratio between the number of Elementary Schools (SD) and MI (both private and public) in Haurgeulis District is 5:1; or the number of SD is 41 consisting of 31 public elementary schools and 10 private elementary schools, while the number of MI is only 8, all of which are private. It can be argued that public interest and the government's response to MI are still relatively low, partly because there are still relatively few competent teachers.

Authors: Ettinger Anna K. , Risser Lauren , Rahman Shiva , Rigas David , Abromitis Rebecca , Stokes Lynissa R. , Chavis Val , Miller Elizabeth 
Published: October 2022

BACKGROUND AND OBJECTIVES
Promoting positive child and youth health and development requires clear definitions and comprehensive measures of child and youth thriving. The study’s objectives were to identify the scope, range, and gaps in definitions and measures of thriving for children or youth (birth through young adult).

METHODS
Systematic searches of Pubmed, PsycInfo, Health and Psychosocial Instruments, Education Resources Information Center, and Scopus were conducted for articles that included definitions, conceptual frameworks, or measures of child and youth thriving. Inclusion criteria were that the articles: (1) provided a new definition or measure of child thriving, flourishing, or well-being; (2) focused on normally developing children 0 to 24 years old; and (3) were published between 2009 and 2022 in an English language peer-reviewed journal. Studies were categorized by child age, study type, population, and community-identified domains of thriving.

RESULTS
Of the 14 920 articles identified, 113 met inclusion criteria: 34 unique definitions or frameworks, 66 validated measures, and 12 articles presenting both a framework and measure. One-third of the articles focused on early childhood (0–5 years old); 47% on middle childhood (6–11 years old); 72% on adolescence (12–17 years old), and 22% on young adults (18–24 years old).

CONCLUSIONS
Current child thriving definitions, frameworks, and measures could be expanded in their coverage of age and key domains, such as racial equity and safety. Additional frameworks and measures focused on early childhood (0–5 years) and assessing thriving over time are needed.
Effects of nutrient (N, P, K) fertilization on the dynamics of fine roots in tropical rain forests with different soil texture in the Colombian Pacific region
Authors: Quinto Mosquera Harley , Moreno Hurtado Flavio H. 
Published: October 2022

Introduction: Fine root dynamics include production, turnover and decomposition; they are crucial to forest health, affect the entire biogeochemical complex of the ecosystem, and consequently, they substantially affect carbon balance. However, the influence of environmental factors and soil nutrient limitation on fine roots presents considerable uncertainties and has not been studied in tropical forests with more than 7 000 mm annual rainfall. Objective: To measure the effect of fertilization on fine roots in the high precipitation Chocó forest. Methods: We worked in two sites of the Chocó region, Colombia (August 2014-May 2015), where rainfall exceeds 10 000 mm per year. We applied five fertilization treatments (N, P, K, NPK and Control) to two soil type plots. Soil cylinders were removed at pre-established intervals to measure roots. Results: Phosphorus applications increased fined roots; and more fine roots were produced in sandy than in loam soil. The effects of fertilization were related, but not clearly determined by edaphic conditions. Conclusions: In this Chocó forest, the production of fine roots was higher in sandy and nutrient-rich soils but belowground net primary productivity was limited by the content of edaphic Phosphorus.
