Published: January 2021

IntroductionA framework for understanding the interrelationship of individual and environmental factors that influence adolescent health and well-being, as well as opportunities for policy-level interventions, is known as Positive Youth Development (PYD). The current study represents one of the largest studies of Croatian adolescents to date, and aimed to examine associations between school and family factors linked to PYD, and mental health outcomes experienced by Croatian youth.MethodsA multi-site survey study was conducted among adolescents (N = 9,655) residing in the five most populous cities in Croatia, with the aim of examining cross-sectional associations of family and school factors with adolescent mental health. The mean age of participants was 16.3 years (SD = 1.2), and 52.5% of participants were female. School and family factors included school attachment, school commitment, family communication, and family satisfaction. Depression, anxiety, and stress were assessed as outcomes. Multigroup structural equation modeling (SEM) was used to examine relations of interest among female and male adolescents.ResultsAmong school factors, increased school attachment was found to be significantly associated with reduced depression, anxiety, and stress for female adolescents, and with decreased depression and stress for male adolescents. Increased school commitment was significantly associated with decreased depression and anxiety for female adolescents; conversely, an increase in school commitment was associated with an increase in anxiety and stress for male adolescents. Increases in family communication were significantly associated with reduced depression, anxiety, and stress only for male adolescents, while increased family satisfaction was significantly associated with reduced depression, anxiety, and stress for female adolescents and with decreased depression and stress for male adolescents.ConclusionFindings suggest that interventions for mental health promotion and prevention of internalizing problems should address both school and family contexts, and may be more effective when accounting for differing developmental experiences of female and male adolescents.

Published: January 2021

Purpose: Subspine impingement occurs due to a morphologically abnormal anterior inferior iliac spine (AIIS), capable of causing impingement against the distal femoral neck. The purpose of this investigation was to determine the prevalence of AIIS dysmorphism based on specimen sex, race, and age, while introducing a novel anatomic-based classification system.Methods: A total of 1,797 adult cadaveric specimens (n = 3,594 hemipelvises) were analyzed. AIIS with the potential for subspine impingement (SSI) was recorded in each specimen by two independent authors. Specimens with AIIS dysmorphism were then reexamined to determine SSI subtype using a novel descriptive anatomic classification system.Results: AIIS dysmorphism was present in 6.4% (n = 115 of 1,797 specimens) of specimens and 5.2% (n = 186 of 3,594) of hemipelvises. Dysmorphism was significantly more common in male specimens (p = 0.04) and African–American specimens (p = 0.04). No significant overall difference in prevalence was appreciated based on specimen age (p = 0.89). Subtype classification found that 67% of hemipelvises possessed a columnar type AIIS, 30% were bulbous and 3% hook type. Males possessed a significantly higher prevalence of columnar type AIIS dysmorphism (p &lt; 0.001). No significant overall differences in anatomic classification were appreciated based on race (p = 0.12) or when analyzed based on age (p = 0.34).Conclusion: AIIS dysmorphism was present in 6.4% of the 1,797 cadaveric specimens evaluated. African-American and male specimens possessed significantly higher prevalence of AIIS dysmorphism, with no significant difference based on specimen age. Columnar type AIIS dysmorphism was most common. Anatomic classification was not significantly different based on specimen race or age.Level of Evidence: Case Series, Level IV.
Increasing Tool Steel Surface Wear Resistance by Surface Treatment
Authors: Tóth László , Nyikes Zoltán , Umesh Mhatre 
Published: January 2021

Abstract
The industry is imposing increasing wear and tear requirements on tools, which can no longer be satisfied with the development of base materials (tool steels). Surface treatment technologies can provide a solution as the surface of the working tool must be suitable. It can determine a relationship between the hardness, surface roughness and the abrasion resistance of various surface treatments and the coating technologies such as PVD as a result of tool steel surface layers. These relationships form the basis for tool selection and provide a theoretical basis for the design of surface technologies.

Authors: Kovács Ferenc , Fábián Enikő Réka 
Published: January 2021

Abstract
The purpose of our study was to investigate the properties of welded joints formed by 1.5 mm thick plates with a diode laser beam equipment. The technological parameters influence the shape of the weld metal. In the heat affected zone no grain coarsening appeared. Increasing the welding speed, in case of similar laser power, the ferrite content of weld metal decreases. The hardness’ of the streams are higher than that of base metal, but the highest values were measured in heat affected zones.

Published: January 2021

Abstract
This paper shows how microfluidic tools can be used for up-to-date microstructural investigations based on thin film deposition. The construction and production methods of such measuring procedures are introduced, and their application in ellipsometric investigations is shown. By using these tools, the researchers provide the possibility to observe and document the effects of certain fine structural processes in the development of the final microstructure. This paper describes two specific application areas of such microfluidics cells. Microfluidics cells can be used together with both optical microscopy and spectroscopic ellipsometry to understand previously unexplored microstructural changes.

Aprendizaje del concepto de red trófica. Un análisis desde el pensamiento lineal y sistémico
Authors: Hernández Serrato Carol , González-Reyes Ronald Andrés 
Published: January 2021

Este artículo realiza una revisión sistemática del aprendizaje de las redes tróficas en educación básica primaria y secundaria desde el pensamiento lineal y sistémico, discutiendo dificultades y discontinuidades en su comprensión. Tras analizar 65 documentos especializados obtenidos de diversas fuentes electrónicas y repositorios de varias bibliotecas, se estableció que la comprensión de las relaciones inherentes a las redes tróficas desde el pensamiento lineal ocasiona en los estudiantes una visión unidireccional, simplista y que desconoce su complejidad, mientras que el pensamiento sistémico a partir de hipótesis de transición posibilita la construcción progresiva de nociones, desarrollando habilidades cognitivas y estructuras de pensamiento donde prevalece la complejidad, lo multicausal, lo multidireccional y lo interrelacional.

Решение задачи связи в Арктике, а также в тундре, в тайге, в лесу, в море, на полях возможно только с использованием мобильных систем спутниковой связи. ФГУП «Космическая связь» (г. Москва) располагает группировкой спутников, которая постоянно расширяется. Для надежной связи в Арктике и в северных широтах, помимо геостационарных спутников, запущены спутники, движущиеся по высокоорбитальным траекториям. Для переключения со спутника на спутник, входящий в зону видимости абонента, необходимо использовать антенные решетки. Проблема заключается в том, что в настоящее время отсутствуют мобильные терминалы высокоскоростной спутниковой связи, а стоимость зарубежных аналогов препятствует широкому их использованию (достигает 50 тысяч долларов). Обычно радиолокационная связь (РЛС) с фазированной антенной решеткой используется для наблюдения за тысячами угловых точек, для отслеживания сотни целей. Такие требования могут быть выполнены только путем сканирования луча в пространстве в течение микросекунды. Ясно, что необходимо электронное управление лучом, поскольку механически вращать антенну не представляется возможным. Лишь некоторая часть вышеуказанных проблем будет затрагиваться в этой статье, ниже будут представлены электронная модель антенной решетки и её математическая модель
The solution of the communication problem in the Arctic, as well as in the tundra, in the taiga, in the forest, in the sea, in the fields is possible only with the use of mobile satellite communication systems. FSUE "Space Communications" (Moscow) has a constantly expanding group of satellites. For reliable communication in the Arctic and Northern latitudes, in addition to geostationary satellites, satellites moving along high-orbit trajectories were launched. To switch from one satellite to the other included in the subscriber's visibility area, it is necessary to use antenna arrays. The problem is that currently there are no mobile terminals for high-speed satellite communication, and the cost of foreign analogues prevents their widespread use (up to 50 thousand dollars). Typically, a phased array radar is used to track thousands of corner points to track hundreds of targets. Such requirements can only be met by scanning the beam in space for a microsecond. It is clear, that electronic beam control is necessary since it is not possible to mechanically rotate the antenna. Only some of the above problems will be touched upon in this article. An electronic model of the antenna array and its mathematical model is presented
Стан липи дрібнолистої (Tilia cordata Mill.) у зелених насадженнях міста Харків (за даними весняного обстеження)
Authors: Kolienkina M. S. 
Published: January 2021

Досліджено стан дерев липи дрібнолистої (Tilia cordata Mill.) у насадженнях прибудинкової території, вуличних і паркових насадженнях Харкова у період весняного розвитку листя та пагонів, особливості поширення основних симптомів його погіршення та шляхи поліпшення. Загалом обстежено 400 дерев липи дрібнолистої, які умовно розподілено на дві групи: "молодші" (діаметром до 15 см) та "старші" (діаметром понад 20 см). Встановлено, що найкращий санітарний стан (Іс = 1,0) мають "молодші" дерева липи дрібнолистої у Центральному парку культури і відпочинку ім. Горького та Молодіжному парку, а найгірший (Іс = 3,5) – на освітленому боці площі Свободи, у місцях із постійною високою концентрацією вихлопних газів. З'ясовано, що за рівнем дефоліації дерев липи окремі ділянки відрізнялися так само, як і за індексом санітарного стану. Найбільшу поширеність сухих гілок мали дерева на пр. Московський і на освітленій частині площі Свободи. Травмування коріння під час робіт з ремонту доріг і прокладання комунікацій, а також вирубання сусідніх дерев спричиняло поширення кореневої парості на деревах. Опік листя виявлено тільки у вуличних посадках, переважно на освітлених і загазованих ділянках. Оцінено поширеність пошкоджень дерев комахами різних екологічних груп: листогризів, мінерів, галоутворювачів. Установлено, що наприкінці травня у Лісопарку, парках і посадках прибудинкових територіях переважало обгризання листя липи дрібнолистої комахами (67-80 % від усіх пошкоджених листків). Частка листків з мінами становили тільки 5 % від усіх листків із пошкодженнями у насадженнях прибудинкових територіях і 13 % – у Лісопарку. Частка листків із галами серед листків із пошкодженнями у молодих дерев липи зростала від вулиць (6 %) до прибудинкової території і парків (20 і 33 % відповідно), а у старших насадженнях була практично однаковою (20-24 %) на вулицях, у прибудинкових територіях і парках, а у Лісопарку становила тільки 13 %, оскільки в останньому випадку значна кількість листків мали ознаки обгризання та мінування. Водночас через порівняно невелику чисельність усіх шкідників листя вони не конкурували один з одним і на початку вегетаційного періоду не заподіювали шкоди.

Published: January 2021

This paper evaluates short-term outcomes of community-engaged learning (CEL) initiatives within the field of user experience design (UXD). Qualitative data were gathered through a thematic analysis of 101 summative student reflections and 22 interview transcripts from 19 community partner organizations. Quantitative findings resulted from an analysis of 94 student surveys. Findings offer preliminary support for CEL initiatives in UXD education and reveal that CEL benefits both students and community partners. Students garnered UXD competencies, interpersonal skills, and increased empathy through participation in CEL initiatives. Community partners gained useful deliverables and an increased understanding of the discipline of UXD as part of their CEL engagement. Two primary recommendations are suggested for improving future CEL engagement: (1) designating a coordinator/point of contact to alleviate the management burden by centralizing communications; (2) providing a clear outline of the engagement deliverables and timelines up front. Este documento evalúa los resultados a corto plazo del aprendizaje a través de la participación comunitaria (CEL, por sus siglas en inglés) dentro del campo del diseño de la experiencia del usuario (UXD por sus siglas en inglés).

Los hallazgos cuantitativos se obtuvieron del análisis de encuestas realizadas a 94 estudiantes. Estos resultados ofrecen un apoyo preliminar a las iniciativas de CEL en la educación UXD y revelan que CEL beneficia tanto a los estudiantes como a los integrantes de la comunidad. Los estudiantes adquirieron habilidades UXD, mejoraron sus relaciones interpersonales y demostraron una mayor empatía a través de la participación en iniciativas CEL. Los integrantes de la comunidad obtuvieron muy buenos resultados y una mayor comprensión de la disciplina de UXD como parte de su compromiso con CEL. Se sugieren dos recomendaciones fundamentales para mejorar la participación futura de CEL: (1) designar un coordinador o punto de contacto para aliviar la carga administrativa y centralizar las comunicaciones; (2) proporcionar desde el principio un esquema claro del compromiso para las entregas de los resultados y sus correspondientes plazos.

Abstract
We present anisotropy results for anomalous cosmic-ray protons in the energy range ∼0.5–35 MeV from Cosmic Ray Subsystem (CRS) data collected during calibration roll maneuvers for the magnetometer instrument when Voyager 2 (V2) was in the inner heliosheath. We use a new technique to derive for the first time the radial component of the anisotropy vector from CRS data. We find that the CRS-derived radial solar wind speeds, when converted from the radial components of the anisotropy vectors via the Compton–Getting (C–G) effect, generally agree with those similarly derived speeds from the Low Energy Charged Particle experiment using 28–43 keV data. However, they often differ significantly from the radial solar wind speeds measured directly by the Plasma Science (PLS) instrument. There are both periods when the C–G-derived radial solar wind speeds are significantly higher than those measured by PLS and times when they are significantly lower. The differences are not expected nor explained, but it appears that after a few years in the heliosheath the V2 radial solar wind speeds derived from the C–G method underestimate the true speeds as the spacecraft approaches the heliopause. We discuss the implications of this observation for the stagnation region reported along the Voyager 1 trajectory as it approached the heliopause inferred using the C–G method.

Abstract
The detection of gravitational waves (GWs) from a binary neutron star (BNS) has opened a new window on gravitational wave astronomy. With current sensitivities, detectable signals coming from compact objects like neutron stars turn out to be a crucial ingredient for probing their structure, composition, and evolution. Moreover, astronomical observations on pulsars and their mass–radius relations place important constraints on the dense matter equation of state. In this paper, we consider a homogeneous and unpaired charge-neutral three-flavor interacting quark matter with

corrections that account for the moderately heavy strange quark instead of the naive MIT bag model. We perform a detailed analysis of strange quark stars in the context of the recently proposed 4D Einstein–Gauss–Bonnet (EGB) theory of gravity. However, this theory does not have standard 4D equations. Thus, we show that the equivalence of the actions in the regularized 4D EGB theory and in the original one is satisfied for a spherically symmetric spacetime. We pay particular attention to the possible existence of neutron stars of mass compatible with

. Our findings suggest that the fourth-order correction parameter (a
4) of the quantum chromodynamic perturbation and coupling constant α of the GB term play an important role in the mass–radius relation as well as the stability of the quark star. Finally, we compare the results with the well-measured limits of pulsars and their mass and radius extracted from the spectra of several X-ray compact sources.
Amplitude Modulation of Short-timescale Hot Spot Variability

Published: January 2021

Abstract
Variability of Classical T Tauri stars (CTTS) occurs over a vast range of timescales. CTTS in particular are subject to variability caused by accretion shocks, which can occur stochastically, periodically, or quasi-periodically on timescales over a few days. The detectability of young planets within these systems is likely hampered by activity; therefore, it is essential that we understand the origin of young star variability over a range of timescales to help disentangle stellar activity from signatures of planetary origin. We present an analysis of the stochastic small-amplitude photometric variability in the K2 lightcurve of CI Tau occurring on timescales of ≲1 day. We find the amplitude of this variability exhibits the same periodic signatures as detected in the large-amplitude variability, indicating that the physical mechanism modulating these brightness features is the same. The periods detected are also in agreement with the rotation period of the star (∼6.6 days) and the orbital period of the planet (∼9.0 days) known to drive pulsed accretion onto the star.
