Authors: León González María Pilar , González-Martí Irene , López Sánchez Guillermo Felipe , Contreras Jordán Onofre Ricardo
Published: November 2021

La imagen corporal es un constructo de relevancia social dada su repercusión en la salud física y mental. La investigación de este constructo en edades tempranas ha recibido escasa atención a pesar de que algunos autores han demostrado que existe preocupación hacia el cuerpo en edad preescolar. Este estudio de diseño mixto tuvo como objetivo medir la percepción del tamaño corporal, el cuerpo deseado y la insatisfacción corporal en niños de edad temprana. Para ello, se utilizó la Escala Corporal para Preescolares, compuesta de cuatro figuras de niños con diferentes estados de peso, la cual fue administrada a 176 participantes de 4 y 5 años, de los cuales 96 fueron chicos y 80 fueron chicas. Los resultados mostraron que la percepción del tamaño corporal fue inexacta en ambos sexos y edades, tendiendo hacia una mayor sobreestimación en las niñas. También se observó que la mayoría de los participantes eligieron una figura deseada diferente a la percibida, especialmente el sexo femenino. Sin embargo, este hallazgo no necesariamente reflejaría la existencia de insatisfacción corporal, como sugieren los datos cualitativos. Las respuestas de los participantes parecen reflejar una ligera conciencia corporal. Se necesitan futuros estudios que ahonden más en el desarrollo de la imagen corporal en edades tempranas.

Published: November 2021

El pensamiento matemático informal fue analizado a partir de precursores específicos y generales. El presente estudio se focalizó en niños y niñas chilenos en torno a cuatro años de edad provenientes de establecimientos públicos que atienden a población de mayor vulnerabilidad social (N=137). Los hallazgos indican que ambos tipos de habilidades son parte de una base importante para el pensamiento matemático informal. El modelo general de regresión múltiple explica el 48.4% de la variabilidad de las puntuaciones obtenidas en el instrumento TEMA 3, relevándose como principales precursores, en orden de importancia, la comparación no simbólica, la comparación simbólica, memoria de corto plazo verbal, la velocidad de procesamiento, y la memoria viso-espacial, respectivamente. Asimismo, exceptuando la doble tarea y el conocimiento de conceptos, no se encontraron diferencias en los modelos explicativos al comparar niños y niñas. Los hallazgos fundamentan la necesidad de contar con un apoyo sistemático y prácticas de monitoreo en estas áreas en ciclos educativos iniciales con la finalidad de disminuir y evitar posibles dificultades de la matemática en general.

Mammoth tusk jewelry in the Yakut culture: retrospective analysis and current state
Authors: Prokopieva Aleksandra Nikolaevna , Yakovleva Kapitolina Maksimovna , Sleptsova Aitalina Alekseevna
Published: November 2021

This article is dedicated to the history of making jewelry from mammoth tusk in the Yakut culture. The hypothesis is advanced that Yakut mammoth tusk carving stems from the local traditions of wood carving and scrimshaw, and represents the raw material for making household items for the local population, and use of tusk as a raw material is associated with the appearance of the first professional scrimshaw craftsmen in Yakutia. The first part of the article examines the history of tusk carving and the prerequisites for the emergence of the new direction in jewelry. The second part of the article describes the peculiarities of making mammoth tusk jewelry in the modern Yakut culture. The current problems of taking, sale and use of mammoth tusk are relevant topics in the scientific discourse. However, jewelry and souvenirs from mammoth tusk, as well as the origins of modern scrimshaw in Yakutia have not previously become the subject of special research. For giving a better perspective on the problem the author interviewed the Soviet and contemporary artisans. It is established that influence of the Soviet scrimshaw school is still traced in modern neo-mythologized representations. The pliability of the material and availability of the raw materials for the Yakut craftsmen substantiated the popularity of the mammoth tusk and its adaptability to modern fashion trends.
Shale adhesion force measurements via atomic force microscopy

Published: November 2021

Wettability of sedimentary rock surface is an essential parameter that defines oil recovery and production rates of a reservoir. The discovery of wettability alteration in reservoirs, as well as complications that occur in analysis of heterogeneous sample, such as shale, for instance, have prompted scientists to look for the methods of wettability assessment at nanoscale. At the same time, bulk techniques, which are commonly applied, such as USBM (United States Bureau of Mines) or Amott tests, are not sensitive enough in cases with mixed wettability of rocks as they provide average wettability values of a core plug. Atomic Force Microscopy (AFM) has been identified as one of the methods that allow for measurement of adhesion forces between cantilever and sample surface in an exact location at nanoscale. These adhesion forces can be used to estimate wettability locally. Current research, however, shows that the correlation is not trivial. Moreover, adhesion force measurement via AFM has not been used extensively in studies with geological samples yet. In this study, the adhesion force values of the cantilever tip interaction with quartz inclusion on the shale sample surface, have been measured using the AFM technique. The adhesion force measured in this particular case was equal to the capillary force of water meniscus, formed between the sample surface and the cantilever tip. Experiments were conducted with a SiconG cantilever with (tip radius of 5 nm). The adhesion forces between quartz grain and cantilever tip were equal to 56.5 ± 5 nN. Assuming the surface of interaction to be half spherical, the adhesion force per area was 0.36 ± 0.03 nN/nm2. These measurements and results acquired at nano-scale will thus create a path towards much higher accuracy-wettability measurements and consequently better reservoir-scale predictions and improved underground operations.

Endovascular treatment of superior vena cava syndrome does not preclude continued use of indwelling hemodialysis and chemotherapy lines
Authors: Casey Molly , Desai Sagar , Khanna Vinit
Published: November 2021

Obstruction of the Super Vena Cava (SVC) can result in symptoms, such as facial plethora and swelling, and be due to a variety of underlying causes besides lung malignancies, the rates of which have changed over time; the underlying etiology is used to determine the best management strategy. This case report aims to discuss the role of etiology in determining the best initial treatment for SVC syndrome (SVCS) and outlines the unique management for a patient that represents the changing demographics of SVCS causes. A 73-year-old male with end-stage renal disease and metastatic carcinoma of the colon presented with swelling of the jaw, neck, and tongue. Computed tomography (CT) scan showed chronic thrombosis of the SVC and bilateral brachiocephalic veins. He had been receiving hemodialysis and chemotherapy through central venous catheters (CVCs) that traversed the SVC and terminated in the right atrium. Treatment involved double-barrel stent reconstruction of the SVC with a snare technique to temporarily reposition the chemotherapy port catheter and exchange of the hemodialysis catheter. After this single procedure, he experienced relief of symptoms without disrupting the use of his CVCs for further hemodialysis or chemotherapy appointments. For cases of SVCS due to underlying lung malignancies, which has been and remains the most common cause, endovascular stenting is reserved as a palliative measure when treatment of a refractory malignancy fails to resolve the obstruction and for when symptoms are severe because most cases are not life-threatening. However, increased use of CVCs has caused a rise in SVCS due to thrombosis, for which stenting is the first-line treatment. Of the few previously published case reports that depict using a snare technique to temporarily reposition a CVC, they all describe cases due to lung malignancies. Outlining this case presentation can increase awareness of thrombotic stenosis as an increasingly common cause of SVCS, which may occur in patients with a broader range of underlying conditions, ages, and life expectancies and require a wider array of physicians to be knowledgeable of management strategies. Furthermore, detailing this unique technique can provide therapeutic alternatives that show how endovascular interventions do not disrupt interdisciplinary treatment plans or preclude continued use of CVCs. While stenting technology has improved dramatically since its inception, follow-up on stent patency will help determine if expanding treatment for lower acuity cases is beneficial. Endovascular stenting is the treatment of choice for thrombotic causes of SVCS, which is becoming more common due to the increased use of CVCs. Techniques to temporarily reposition CVCs intra-procedurally allow for limited disruption in multidisciplinary treatment plans for patients with complex underlying conditions.

Authors: Ramasamy Thendral , Veeraiah Surendran , Balakrishnan Kalpana
Published: November 2021

Objectives:

This study aims to explore the psychosocial issues faced by the primary caregivers of advanced head and neck cancer patients with the primary objective to understand their experiences within social context.

Materials and Methods:

Burden and QOL of caregivers (n = 15) were quantified using Zarit Burden Interview schedule and caregiver quality of life index-cancer (CQOLC), respectively. Primary caregivers (n = 10) were interviewed using semi-structured interview schedule. Thematic analysis was employed to analyse the qualitative data. Descriptive statistics was used for quantitative data.

Results:

Four major themes emerged: (1) Impacts of caregiving, (2) coping with caregiving, (3) caregiver’s appraisal of caregiving and (4) caregiver’s perception of illness. Majority (73.3%) of the caregivers had QOL below 100. The mean CQOLC score was 73.07 (SD 24.17) and most (46.7%) of the caregivers reported mild-to-moderate burden, while 27% had little to no burden. The mean ZBI score was 32.4 (SD 18.20).

Conclusion:

Caregiving impacts the physical, emotional, financial and social aspects of caregiver’s life. Caregivers adopt active coping strategies to overcome the impacts of caregiving. Family acts as a major source of strength to manage the emotional constraints faced by Indian caregivers. Cultural beliefs and values of caregivers influence their appraisal of caregiving situation. Majority of the caregivers experienced mild-to-moderate burden while most of the caregivers scored low on QOL.

Эффективность информационно-измерительных систем, применяемых в таких областях как радиолокация, связь, во многом зависит от их устойчивости к действию преднамеренно создаваемых помех. В статье рассматривается подход к повышению помехоустойчивости информационно-измерительных систем путем адаптации их структуры к изменениям сигнально-помеховой обстановки. Методами теории оптимизации динамических систем случайной структуры синтезирован алгоритм управления структурой информационно-измерительной системы, в состав которой входит радиолокационная станция. Показаны структурные схемы вновь разрабатываемых устройств. Приведены результаты исследования разработанного алгоритма управления структурой информационно-измерительной системы, подверженной действию организованных помех, подтверждающие его практическую значимость. Результаты исследований могут быть использованы при разработке информационно-измерительных и управляющих систем в области управления воздушным движением, самонаведения подвижных объектов, в связных и навигационных системах, других системах, располагающих открытыми входными информационными каналами.

The effectiveness of information and measurement systems used in such areas as radar, communications, largely depends on their resistance to the action of deliberately generated interference. The article discusses an approach to increasing the noise immunity of information-measuring systems by adapting their structure to changes in the signal-interference environment. Using the methods of the theory of optimization of dynamic systems of random structure, an algorithm for controlling the structure of an information-measuring system, which includes a radar station, has been synthesized. The block diagrams of newly developed devices are shown. The results of the study of the developed algorithm for controlling the structure of the information-measuring system exposed to organized interference are presented, confirming its practical significance. The research results can be used in the development of information-measuring and control systems in the field of air traffic control, homing of mobile objects, in communication and navigation systems, and other systems with open input information channels.

Герценбергит SnS встречен в околомиароловом комплексе гранитного олигоклаз-микроклинового типа пегматита Вез-Дара (жила 86) (Ю-З Памир, Таджикистан) в среднезернистой калишпат-кварцевой породе. Второстепенные минералы: биотит, шерл (графика с кварцем), гранат ряда спессартин – альмандин, альбит. Образует неправильные агрегаты, короткие прожилки до 5 мм, сложенные пластинчатыми зернами 40–80 х 10–25 мкм, замещенные «варламовитом», в срастании с гетитом, цирконом, черчитом-(Y), Sc-содержащим Mn-танталониобатом. Цв. стально-серый (свежий скол), темно-серый (выветрелая поверхность). В отраженном свете белый: Rg = 49.9, Rp = 43.5% (560 нм). Двуотражение слабое (воздух), отчетливое (в иммерсии). Анизотропия с цветными эффектами на воздухе сильная, в иммерсии – очень сильная. Микротвердость 79–86 кгс/мм2 (нагрузка 20 г). Приведена порошкограмма. Параметры ячейки a = 4.331(2), b = 11.195(3), c = 3.983(2) Ǻ. Хим. состав (микрозонд, вес.%): Sn 77.86–79.01; S 20.96–21.45. Pb, Cu, Sb, Fe ниже предела обнаружения. Формула Sn0.99–1.02S1.00. Предполагается прямая кристаллизация в восстановительных условиях из обогащенного Sn+2 кислого раствора на низкотемпературном гидротермальном этапе становления пегматита. Частичное замещение «варламовитовым» агрегатом может быть обусловлено как неустойчивостью SnS при увеличении pH растворов на гипогенном этапе, так и результатом гипергенного окисления. Является первой находкой в Таджикистане.

We report a bottom-up approach to immobilize catalysts into MOFs, including copper halides and gold chloride in a predictable manner. Interestingly, the structures of MOFs bearing NHC metal complexes maintained a similar 4-fold interpenetrated cube. They exhibited exceptionally high porosity despite the interpenetrated structure and showed good stability in various solvents. Moreover, these MOFs possess high size activity depending on the size of the substrates in various reactions, compared to homogeneous catalysis. Also, the high catalytic activity of MOFs can be preserved 4 times without significant loss of crystallinity. Incorporation of the various metal complexes into MOFs allows for the preparation of functional MOFs for practical applications.
A new fish-based index of biotic integrity for lowland rivers in Flanders (Belgium)

Published: November 2021

The first fish-based index to assess the ecological quality of lowland rivers in Flanders (Belgium) is based on data obtained from different fishing techniques without considering the gear specificity. As a consequence, this index could not be intercalibrated with other European indices which concentrate on one gear type only. In order to comply with the European Water Framework Directive, we developed a new fish-based index using data obtained from surveys in rivers with electric gear only. All 293 selected rivers belonged to the bream or barbel zone. An updated reference list of fish species was compiled based on previous work and recent data. Abiotic data were collected according to standard methods and habitat quality of all surveyed sites was pre-classified using pressure indicators. To develop the new index candidate metrics were selected from the literature and metric values were calculated. Linear mixed regression models selected metrics based on their response to the pre-classified habitat status. Correlation tests were performed to avoid redundancy among responsive metrics. Boundaries for metric scores were defined based on the calculated metric values. The new index of biotic integrity (IBI) was calculated by summation of the metric scores, and transformed to an ecological quality ratio (EQR), ranging between 0 and 1. Five integrity classes, ranging from bad to maximal ecological potential, were attributed and compared to the pre-classified habitat status of the site. In addition, the new index was also validated with an independent set of data. The new IBI proved to successfully assess the ecological status of the rivers.

Introduction. The problem of traffic noise on the road network of cities is considered. The reasons for the annual increase in the sound level on urban roads in Russia and abroad, as well as the factors contributing to this, are investigated. The purpose of the work: on the basis of the conducted theoretical research and the obtained experimental data, to develop measures that contribute to improving the environmental safety of the city, to build a model of the dependence of the noise level on the traffic intensity, taking into account the peculiarities of the organization of traffic and urban planning in Tambov.Materials and methods. Sound level measurements on the Tambov road network were carried out in accordance with the methodology specified in GOST 20444-2014, which provided for the assessment of the actual noise characteristics of traffic flows (by vehicle type). The measurements were carried out using a noise meter in summer and winter during peak and inter-peak times on weekdays.Results. The study of the noise level on the Tambov street and road network showed an excess of this indicator relative to the norms by 7-18%, depending on peak and inter-peak time, as well as the summer and winter period. The dependence of the traffic intensity of vehicles on the noise level in the summer and winter periods is constructed.Discussion and conclusion. The measures were proposed, including urban planning, to reduce the sound level in the areas under consideration. The complex of these measures will reduce the level of traffic noise on the city’s road network by an average of 5-15 dBA.

Authors: Morrissey Gina
Published: November 2021

More than 200 organisations across New Zealand have been found non-compliant with the Holidays Act since its enactment in 2003. Thousands of employees have been underpaid by a combined amount in the millions and employers have incurred significant costs to remediate and maintain compliance. This article considers the issues with the Act, the impacts, and whether the changes proposed by the Holidays Act Taskforce will address these issues. It then sets out an alternative approach.
