A System for Computer-Aided Gating Design for Single and Multi-Cavity Injection Moulds
Authors: Kumar Vijay , Virdi Roshan Lal 
Published: August 2023

Design of injection moulding dies (called moulds) is a time consuming and complex activity that requires domain knowledge and vast experience of the die-designer besides information about manufacturing resources, part geometry, number of cavities, etc. The gating design is of great importance for reducing lead time and cost of part produced and to achieve first-piece-right. The gating design encompasses several steps, involves complex computational work, and requires a number of iterations. In the present research work an attempt has been made to develop a computer-aided system, which facilitates gating design of an injection mould taking part CAD file as input. The gating parameters are calculated by taking part geometry, material and number of cavities as input. The proposed system is divided into three modules, namely Gate design, Runner design and Sprue design. To demonstrate the capabilities of proposed system, it was tried for a number of parts and the results for two industrial case study parts are presented. Proposed system is a step forward to design-manufacturing integration for injection moulding process.

Published: August 2023

At JSW Steel Limited, Salem Works (JSWSL), hydrogen induced cracks contribute more to ultrasonic defects in medium carbon molybdenum steel such as JDM 1046. As hydrogen tend to escape during cooling due to its smaller atomic radius and high diffusivity in the solid phase, experiments were conducted to reduce hydrogen induced cracks by slow cooling of blooms/bars. A study was conducted wherein few blooms/bars of the same heat were slow cooled and others were normal cooled (air cooled). After cooling, hardness, microscopic and ultrasonic examinations were carried out on these blooms/bars. Results revealed that, the slow cooled blooms/bars were found to be free from ultrasonic defects and showed reduced as rolled hardness when compared with air cooled blooms/bars. Slow cooling resulted in defect free steel against 15-35% defect levels observed in air cooled bars. The paper discusses various metallurgical changes, which facilitated the elimination of hydrogen in JDM 1046 grade steel.

Published: August 2023

A turbo expander also referred as an expansion turbine, is a centrifugal or axial flow turbine through which a high pressure gas is expanded to produce work that is often used to drive a compressor. The low pressure exhaust gas from the turbine is at a very low temperature that is 120K or less depending upon the operating conditions. It is widely used as sources of refrigeration in industrial processes and liquefaction of gases such as oxygen, nitrogen, helium, argon and krypton. A cryogenic system needs many components, compressor, heat exchanger, expansion turbine, instrumentation, vacuum vessel etc. At present most of these process plants operate at medium or low pressure due to its inherent advantages. A basic component which is essential for these processes is the turbo expander. The main aim of this project to attain a minimum temperature and pressure and to study the variation of Mach number and entropy. This is done by computational fluid flow analysis of high speed rotating turbine. This involves with the three dimensional analysis of flow through a radial expansion turbine, using nitrogen as flowing fluid. The work is performed on various modules of Ansys that is BladGen, TurboGrid, CFX-Pre, CFX-Post. Bladegen is used to create the model of turbine using available data of hub, shroud and blade profile. Turbogrid is used to mesh the model. CFX-Pre is used to define the physical parameters of the flow through the Turbo expander. CFX-Post is used for examining and analyzing results. Using these results variation of different thermodynamic properties like Temperature, Pressure, Mach number, entropy etc. inside the turbine can be seen. Several graphs are plotted showing the variation of pressure, temperature, entropy and Mach number along streamline and span wise to analyze the flow through cryogenic turbine.
Enhancing Durability of Hot Work Tool Steel by Duplex Treatments: A Review
Authors: Chander Subhash , Chawla Vikas 
Published: August 2023

The abrasive wear unitedly with thermo-mechanical fatigue and plastic deformation is a critical factor of the process of failure of forging dies during the forging of components with close tolerances and not subject to further mechanical treatment. The failure rate of forging dies are also greatly influenced by the variety of the shapes of the forging and the precision with which these are made. The effective way to improve the durability of forging dies is a modification of surface properties by the constitution of layers or coatings having appropriate properties. Among huge available techniques; Plasma nitriding along with suitable coating formed by physical vapor deposition (PVD) technique; commonly known as Duplex/Hybrid treatment; is widely used, allows control of surface microstructure, enhance wear resistance, corrosion resistance and fatigue resistance. This had been noted that Duplex Treatment can increase the wear resistance of the tool/die up to 30%. The tribological behaviours of duplex treated dies in hot forging are reviewed and presented here. Some commonly used surface treatments as well as coatings in hot forging dies are given. Eventually, xperimental results obtained by various researchers could be used in theory and model developments for hot forging process and die materials at high temperatures. The review also showed the great potential in further investigations in tribology.

Published: August 2023

Особенностью современного периода развития всех отраслей и сфер агропромышленного комплекса является ускорение научно-технического прогресса на основе инновационных процессов. Развитие АПК направлено на наращивание научно-технического потенциала с целью поэтапного снижения зависимости от импорта технологий, технических средств и других ресурсов. Состояние современного агробизнеса весьма нестабильно, что связано, прежде всего, с высокой рискованностью и большой капиталоёмкостью, порождающей низкую экономическую доступность к инновационным продуктам. Зачастую элементарное отсутствие денежных средств не позволяет аграриям наращивать инновации. В сельском хозяйстве инновации охватывают все аспекты производственного цикла по всей цепочке создания добавленной стоимости: от возделывания сельскохозяйственных культур – до взаимодействия с конечными потребителями. Наиболее распространёнными инновациями в сельскохозяйственном производстве являются: технологические, маркетинговые и организационные (более эффективная организация всех управленческих процессов, организация рабочих мест и т. д.). Установлено, что наибольший удельный вес в сельском хозяйстве занимают технологические инновации, на втором месте – организационные, на третьем – маркетинговые.
A feature of the modern period of development of all branches and spheres of the agro-industrial complex is the acceleration of scientific and technological progress based on innovative processes. The development of the agro-industrial complex is aimed at increasing scientific and technical potential in order to gradually reduce dependence on imports of technologies, technical means and other resources. The state of modern agribusiness is very unstable, which is primarily due to high risk and high capital intensity, which generates low economic accessibility to innovative products. Often, the elementary lack of funds does not allow farmers to increase innovation. In agriculture, innovations cover all aspects of the production cycle along the entire value chain: from crop cultivation to interaction with end users. The most common innovations in agricultural production are: technological, marketing and organizational (more efficient organization of all management processes, organization of workplaces, etc.). It is established that technological innovations occupy the largest share in agriculture, organizational innovations take the second place, marketing innovations take the third place.

Chile y Corea del Sur, 1973-1976: Diplomacia Militar y Geopolítica Transpacífica.
Authors: Ross Orellana César , Garay Vera Cristián 
Published: August 2023

Este artículo describe el interés de Augusto Pinochet y los militares chilenos por la República de Corea (ROK) o Corea del Sur. Aunque se ha argumentado que la apertura al Asia Pacífico fue principalmente motivado por un interés económico, postulamos que estas relaciones económicas también pueden ser vistas como una estrategia consciente para sortear el bloqueo democrático, revelando un alto componente político en las relaciones con Corea del Sur.
La hipótesis de este artículo es que, desde el principio, hubo un enfoque geopolítico centrado en cuestiones de seguridad y defensa, que buscaba reforzar el frágil equilibrio del poder mundial en la década de 1970, las repercusiones de su aislamiento político y las tensiones vecinales entre 1974 y 1979.
Para ello se revisó bibliografía especializada, documentación del Archivo Histórico General del Ministerio de Relaciones Exteriores de Chile, escritos de Augusto Pinochet Ugarte y otros autores militares de la época, contenidos en revistas militares y memorias.
Conferencia magistral de la embajadora Alicia Bárcena, con ocasión de la conmemoración de los 50 años del golpe de Estado en Chile
Authors: Americana Encrucijada 
Published: August 2023

Agradezco la cordial invitación de la Universidad Alberto Hurtado para compartir con ustedes algunas reflexiones en el marco de la conmemoración de los 50 años del golpe de Estado y con ello la trágica ruptura de la democracia, que abrió una profunda cicatriz en la historia de Chile cuyas grietas llegan hasta el día de hoy entre familiares, amigos y colegas. Un hecho que golpeó las conciencias de muchas y muchos que, a la distancia, observábamos el inédito proyecto transformador que lideraba Salvador Allende, primer presidente socialista del mundo electo democráticamente.
Agradezco en especial a mi muy querido Armando di Filippo, con quien me une una muy estrecha amistad e innegables coincidencias en el campo de las ideas políticas y, por supuesto, de nuestro respectivo paso por la CEPAL (Comisión Económica para América Latina).
Más que intentar una reflexión académica de aquel aciago momento, quisiera recoger hitos de la memoria de este pueblo tan querido que interpela mi historia personal. Este recuerdo me revive la esperanza limpia que despertó en mí generación, y en muchas generaciones de latinoamericanos, la historia de una patria que había logrado en las urnas darse un gobierno de cambios, con vocación de justicia e igualdad, de la mano de un líder de estatura continental.
ANÁLISE CRÍTICA ACERCA DA IMPOSSIBILIDADE DE MODIFICAÇÃO DAS ASTREINTES VENCIDAS NO NOVO CPC SOB UMA PERSPECTIVA HUMANISTA CONSTITUCIONAL
Authors: Cavalcanti Neto Gabriel de Oliveira , Pimentel Alexandre Freire , Holanda Irving William Chaves 
Published: August 2023

O presente estudo pretender discorrer, através da análise crítica do discurso jurídico (ACDJ), sobre a (im)possibilidade de modificação das astreintes vencidas no novo Código de Processo Civil – NCPC, ora sob o viés da dogmática jurídica, ora à luz de uma perspectiva humanista constitucional.
O pressuposto deste ensaio é o estudo empírico de casos concretos julgados por alguns sodalícios pátrios, dentre os quais se destacam o Tribunal de Justiça do Estado de Pernambuco – TJPE e o Superior Tribunal de Justiça – STJ. O intuito da pesquisa é aferir se – na prática (direito vivo) – o Poder Judiciário tem feito glosas sobre o quantum de multas cominatórias (astreintes) vencidas que afetem de forma exagerada os devedores, pondo em risco valores constitucionais.
A importância da lavra se justifica na medida em que há um preclaro cotejo entre a zetética (perspectiva humanista constitucional) e a dogmática (regra insculpida no NCPC, art. 537), notadamente quando estiver em jogo a possibilidade de ruína de particulares e/ou o fechamento de empresas.
Estes reflexos revelam que a norma processual – se cumprida à risca – pode vir a malferir princípios constitucionais em casos concretos, tais como, v.g., a função social da empresa e da propriedade (CRFB/88, art. 5º, inciso XXIII c/c art. 173, § 1º, inciso I) ou a dignidade da pessoa humana (a menor onerosidade ao devedor), cf. NCPC, art. 805 c/c art. 1º, inciso III, da CF/88.

A NBR ISO 14001 como referência para avaliação dos aspectos e impactos ambientais associados ao manejo de medicamentos antineoplásicos numa central de abastecimento farmacêutico
Authors: Da Silva Ronaldo Ferreira , Moura Leonardo de Lima 
Published: August 2023

As questões ambientais ocupam cada vez mais espaço na agenda de empresas, academia e sociedade civil. Neste contexto, a adoção de práticas de gestão ambiental pelas organizações deixou de ser meramente regulatória, passando a constituir parte de suas estratégias competitivas. Contudo, muitas instituições cujas atividades têm potencial para causar danos ao meio ambiente e à saúde pública, ainda enfrentam dificuldades para se adequar à legislação vigente como, por exemplo, os hospitais. Entretanto, a implementação de um sistema de gerenciamento ambiental nessas organizações pode minimizar diversos impactos ambientais decorrentes de suas atividades e a norma ISO 14001 estabelece diretrizes que facilitam esse processo. Este artigo descreve uma análise preliminar para a implantação de um modelo de gestão ambiental baseado nas diretrizes da ISO 14001, por meio da avaliação das diversas atividades que compõem o manejo dos medicamentos antineoplásicos na central de abastecimento farmacêutico de um hospital de alta complexidade. Os resultados mostram que a maior parte das atividades realizadas apresenta aspectos ambientais como a geração de resíduos e derramamento de fármacos antineoplásicos que podem ocasionar impactos ambientais como a contaminação de água e solos. Tais impactos têm baixa probabilidade de ocorrência, alta severidade, abrangência local e podem ocorrer em condições emergenciais de operação. Como conclusão, o estudo demonstra a necessidade de um maior enfoque das organizações hospitalares na implantação de sistemas de gerenciamento ambiental e no treinamento e capacitação dos diversos profissionais em função da possibilidade de geração de impactos ambientais pelo manejo destes medicamentos.
