Published: June 2021

Представлено конструктивно-компоновочное решение стержней Y-образных и Ψ-образных очертаний в фермах с ромбической решеткой или фермах с ромбической решеткой и полустойками (полуподвесками), техническая новизна которого подтверждена результатами патентной экспертизы. Универсальность этого решения для ферменных конструкций обеспечивает ту эффективность, с какой оно применимо к грузовым верхним поясам, грузовым нижним поясам или грузовым верхним и нижним поясам одной и той же решетки. Повышена степень унификации фермы из прямоугольных гнутосварных профилей (профильных труб) за счет использования в верхнем поясе форм и наружных габаритов поперечных сечений, принятых для нижнего пояса. При этом ресурсы несущей способности разнятся между ними в пределах однопроцентного порога, что обеспечивает необходимую и достаточную равнопрочность обоих поясов для их более рациональной унификации. Узловые соединения стержней разных очертаний с верхними поясами позволяют оптимизировать опорные условия настилов и прогонов с уменьшением размеров их грузовых площадей. Возрастание общего количества прогонов приводит к снижению их суммарной массы и массы кровельного ограждения, что весьма актуально для вариантного и оптимального проектирования строительных конструкций с учетом риска лавинообразного обрушения. Выявлена перспективность применения нового технического решения в составе несущих и связевых систем различных зданий и сооружений.
The structural and layout solution of rods of Y-shaped and Ψ-shaped outlines in trusses with a rhombic lattice or trusses with a rhombic lattice and half-posts (half-suspensions) is presented, the technical novelty of which is confirmed by the results of patent examination. The versatility of this truss solution is as effective as it is for load tops, load bottoms, or load tops and bottoms of the same grid. The degree of unification of the truss of rectangular bent-welded profiles (shaped pipes) has been increased due to the use in the upper chord of the forms and outer dimensions of the cross-sections adopted for the lower chord. At the same time, the resources of the bearing capacity differ between them within a one- percent threshold, which ensures the necessary and sufficient equal strength of both belts for their more rational unification. Nodal connections of rods of different shapes with the upper chords allow to optimize the support conditions of decks and purlins with a decrease in the size of their cargo areas. An increase in the total number of runs leads to a decrease in their total mass and the mass of the roofing, which is very important for the variant and optimal design of building structures, taking into account the risk of an avalanche collapse. The prospect of using a new technical solution in the composition of bearing and communication systems of various buildings and structures has been revealed.
HUMAN SECURITY IN EAST AFRICA: THE EAC'S ILLUSIVE QUEST FOR INCLUSIVE CITIZENSHIP
Authors: Walsh Barney 
Published: June 2021

The East African Community (EAC) exemplifies the contradiction of independent Africa's efforts to champion regional integration and the idea of pan-Africanism, whilst maintaining the nation-state model left from colonialism. EAC I, 1967-1977, ultimately collapsed due to its inability to create a regional institutional framework that could supplant the nationalist tendencies of its member states' leaders; and failing to adopt a people-centred inclusive approach to its structure and actions. The resultant human security issues suffered throughout post-colonial East Africa at their essence have been caused by the victorious nationstate's continued failure to offer this inclusive citizenship to its peoples. Despite the EAC II's, 2001-present, espoused people-centred reincarnation, it too has so far failed to create the inclusive citizen, or peoplecentred approach to its development and so risks the continued insecurity of its people.
UBUNTU AS FOREIGN POLICY: THE AMBIGUITIES OF SOUTH AFRICA'S BRAND IMAGE AND IDENTITY
Authors: Le Pere Garth 
Published: June 2021

South Africa's 2011 White Paper on foreign policy, "Building a Better World", is predicated on the far-reaching ambition of how Ubuntu (humanity) and Batho Pele (putting people first) together with their underlying humanist principles will guide the country's external relations. However, while noble, this calculus is poorly conceived as an approach to global issues. The article argues that while still a relatively successful nation brand if measured by marketing indicators, South Africa's normative currency and agency in foreign policy has depreciated considerably, with a direct bearing on its nation brand and identity. These are examined with regard to the security of citizens and the personality of the state and provide a register of the branding and image deficits of the White Paper. Such deficits are then considered in terms of the cosmopolitan vision in South Africa's foreign policy and its moral and normative underpinnings. The article provides examples in both the domestic and global regimes to demonstrate the extent to which South Africa has lost its normative resilience in the conduct of its foreign policy, thus giving rise to ambiguities in its brand image and identity.

Esta nueva entrega de los Cuadernos de Política Exterior Argentina (CUPEA), la primera de 2021, nos encuentra todavía transitando la incertidumbre generada por la pandemia, repetida y, en algunos casos, potenciada si nos retrotraemos a diciembre de 2020.El panorama internacional es realmente complejo, no sólo en lo sanitario sino en la multiplicidad de crisis políticas, intrincados procesos eleccionarios en una variedad de países, el crecimiento exponencial de la pobreza en las regiones subdesarrolladas y una casi generalizada deslegitimación de la “clase política” por parte de los ciudadanos que la percibe como muy alejada de la búsqueda del “bien común”.Nuevas y viejas disputas de poder, los interrogantes acerca de la transición hacia un nuevo orden internacional, la perspectiva de reflotar el multilateralismo, escenarios regionales que no logran superar su fragilidad para dar respuestas cooperativas y un peligroso ascenso de la Geopolítica para leer la realidad global.
Los Cuadernos de Política Exterior Argentina (Nueva época) apuntaron siempre a constituirse en un espacio de actualización académica y de promoción de debates en el campo disciplinar de las Relaciones Internacionales. Precisamente, este propósito así como también la calidad de los artículos, la regularidad de las entregas, la constitución de un Comité Editorial de alto nivel internacional y una base amplia, plural y muy especializada de referees que operan bajo la metodología doble ciego para dictaminar, han sido reconocidos en la Resolución por la cual, en abril de 2021, se incorpora CUPEA al Núcleo Básico de Revistas Científicas Argentinas. Esta decisión, sin dudas, estimula a continuar el proceso de validar la calidad en nuevas instancias a la vez que se convierte en un atractivo para investigadores y docentes que desean publicar sus trabajos.El número 133 de CUPEA cubre un amplio abanico temático de las Relaciones Internacionales y la Política Exterior, que en este caso ha coincidido con temáticas relativas a la región sudamericana. Cuenta con cinco artículos académicos sometidos a referato doble ciego; un artículo de opinión, la sección Misceláneas Universitarias y dos reseñas de libros recientemente editados.
The potential for new materialist justice via Nordic feminist perspectives of law
Authors: Käll Jannice 
Published: June 2021

The Nordic feminist perspectives in law have traditionally been relatively successful in advocating, and effectuating, a feminist perspective of justice both within law and the society. However, Nordic feminist perspectives of law have at least to some degree, at this stage been limited to questions of equality between men and women and to the production of justice within the boundaries of the nation-state. In this article, I take the challenge upon myself of elaborating the notion of justice advanced by new materialist theory as a means to infuse the Nordic feminist perspective in, and on, law. This is pursued by reading new materialist theory and Nordic feminist perspectives of law against each other. In sum, the reading suggests that a focus on new materialist justice could be used to infuse Nordic feminist legal perspectives on justice by both shifting the understanding of law, and justice, as well as its contextual focus.

Published: June 2021

Проведены экспериментальные исследования влияния лучистого теплообмена на переход верхового лесного пожара на постройки IV и V степеней огнестойкости. Лесной верховой пожар моделировался горением штабеля древесины с интенсивностью тепловыделения, близкой к интенсивности при реальных пожарах. Получена зависимость изменения плотности теплового потока от расстояния до кромки горения. Экспериментально определены температура воздуха с подветренной стороны пожара и плотность выпадения искр в зависимости от расстояния. Проверена эффективность защиты растворами ретардантов деревянных строений от возгорания при лучистом теплообмене между факелом пламени пожара и объектом защиты.
Crown fires are the main threat of the combustion transfer from the forest to objects located in it. Fire services dealing with forest fires face the problem how to protect these objects from forest fires. It is proposed to treat the object with retardant solutions before a forest fire approaches. To assess the effectiveness of such tactics for fire protection of objects when exposed to a heat flow from the combustion front there were carried out experiments on large-scale crown fire models. A crown fire is simulated with a pile of wood with a heat release rate of ≈ 13 MW m. The wind is generated by fans, its speed is close to the speed at which a forest fire occurs. Measurements of the heat flux density, medium temperature, and the density of sparks falling downwind of the fire front at different distances and heights were carried out. Calculations were carried out to assess the impact of heat flow on buildings of IV-V degrees of fire resistance. The results obtained are compared with experimental data and they are in good agreement. There have been determined the distances from the fire front at which the fire protection with retardant solutions is effective for structures of IV-V fire resistance degrees at radiant heat exchange.
Coordination, attention visuelle et gestes professionnels dans la rééducation de l’aphasie
Authors: Merlino Sara 
Published: June 2021

Dans cette contribution, nous nous focalisons sur des interactions entre personnes aphasiques et orthophonistes au cours des séances de rééducation de la parole. En soulignant la nature interactive et multimodale des activités thérapeutiques, notre étude se penche sur des phénomènes de coordination et d’établissement et négociation de l’attention visuelle. L’analyse porte sur une collection d’extraits dans lesquels le thérapeute sollicite le regard du patient par l’emploi de plusieurs ressources, dont des directifs qui portent sur le regard. Ces sollicitations permettent de guider l’attention visuelle envers certains éléments du contexte et de négocier des configurations participatives adéquates pour profiter des formes d’étayage offertes par le thérapeute et accomplir les tâches de manière collaborative. Nous soulignons la centralité des gestes professionnels et des ressources corporelles mobilisés par le thérapeute et nous analysons la manière dont le patient est « instruit » à voir ces ressources. En reprenant plusieurs aspects de l’œuvre de Goodwin, notre contribution souligne des pratiques interactives et socialement organisées dans lesquelles prend forme l’institution thérapeutique de traitement de l’aphasie.

Enhancement Mode GaN-FETs in Extreme Temperature Conditions, Part II: Dynamic Parasitic Parameters
Authors: Duraij Martijn S. , Xiao Yudi , Zsurzsan Gabriel , Zang Zhe 
Published: June 2021

Abstract
Parasitic components in eGaN-FETs impact the dynamic performance of switching stages. The capacitances seen, primarily on the output characteristics, of these devices are a main contributor towards switching losses and therefor converter efficiency. Additionally, the threshold voltage of the device has an impact towards the switching speed and therefore the efficiency of a power stage. This study shows the impact of extreme temperatures towards the parasitics that impact the switching behaviour of a power stage. A literature research is conducted exploring the various mechanisms and temperature dependancies, which are then related towards transient operations of eGaN-FETs. A device was chosen to perform measurements on output-, reverse transfer capacitance and threshold voltage while increasing temperature from 100°C op to 225°C. The presented results show a large impact of temperature in these parasisic elements that show that high temperature switch-mode power converters need additional design work to ensure switching performance and lifetime.
Alternative Setup for Long-Duration Low-Duty-Cycle 600°C Ambient Testing of SiC Integrated Circuits
Authors: Izadnegahdar Alain , Booth Stephanie L. , Spry David J. , Neudeck Philip G. 
Published: June 2021

Abstract
A scalable, compact oven testbed system for simultaneously evaluating a multitude of high temperature integrated circuits (ICs) for prolonged operating times of up to 600 °C has been prototyped. The new testbed system enables long-duration high temperature testing in sufficient statistical quantities consistent with standard aerospace electronics engineering standards. This setup is comprised of multiple compact ovens housing chips or packages mounted to ceramic circuit boards. Each oven is a compact 15.2 cm length by 15.2 cm width by 12.7 cm depth with a maximum 400 Watts of heating power. The custom-made silicon oxide ceramic heating block inside each oven is based on a 3D printed design adapted for the easy insertion of the IC device under test (DUT). This innovative design provides the quick insertion of ICs with or without a ceramic package into a 600 °C environment by utilizing a movable 11.43 cm long ceramic substrate with electrical traces extending from the oven hot zone to external standard plastic-based board connectors. Another key oven design feature is the minimization of the DUT exposure to electromagnetic interference (EMI) by utilizing a filtered DC power source to reduce heating element noise. Additionally, the ovens can be configured in a parallel arrangement allowing global data monitoring over a single industrial RS422 serial port. This feature is important for scaling up to test multiple ICs semi-simultaneously. A USB serial port is provided to independently control the operating parameters of each oven such as the oven target temperature and oven ramp rate. The oven temperature can reach up to 600 °C with a confirmed +/− 4 °C maximum deviation across the test zone region. The ramp rate can be programmed from 1 °C/minute up to 10 °C/minute. Furthermore, a programmable switchboard is used to interface with the DUT. This switchboard comprises a National Instruments Peripheral Component Interconnect eXtension for Instrumentation (NI PXI) system and a breakout board to send and receive power, analog or digital test signals. By using this unique oven testbed system, a variety of ICs can now be tested in parallel using the same test components configured for a diverse set of requirements.
