En torno a la fisiopatología del síndrome de piernas inquietas
Authors: García-Borreguero Diego
Published: October 2022

El síndrome de piernas inquietas es un trastorno del sueño y del movimiento, que hasta hace poco tiempo ha recibido una escasa atención. No obstante, los estudios epidemiológicos muestran tasas de prevalencia, en los países occidentales, entre el 5 y el 10%. Su causa es desconocida, pero los estudios neurofarmacológicos, de neuroimagen y neurofisiológicos apuntan a una posible disfunción del sistema dopaminérgico, al menos para los casos idiopáticos. No obstante, las alteraciones encontradas son débiles e inconsistentes, y su localización en el Sistema Nervioso Central es puramente especulativa. Por otro lado, en los últimos años se han realizado avances que sugieren una posible implicación del metabolismo del hierro, así como en el campo de la genética. Se revisan los fundamentos sobre la fisiopatología de este cuadro.
Manejo de los corticoides en la práctica clínica
Authors: Galofré J. C.
Published: October 2022

Los corticoides son ampliamente utilizados por muy diversas especialidades. Sin embargo su uso no está exento de complejidad. El manejo adecuado de estos fármacos requiere tener nociones básicas de fisiopatología y conocer bien las características del corticoide que se pretende emplear: sus equivalencias, vida media en sangre, potencia glucocorticoide y mineralcorticoide relativa o tipo de acción tisular del preparado. Los efectos secundarios son frecuentes y pueden llegar a ser graves, por lo que con frecuencia deben tomarse medidas para minimizarlos. En los casos en los que se administren dosis suprafisiológicas debe evaluarse adecuadamente el estado del eje hipofiso-adrenal al término del tratamiento.
Cambios con la edad, de la influencia del ejercicio físico y la dieta hipocalórica sobre diversos parámetros de salud
Authors: Ferrer J. V. , Calabuig J.
Published: October 2022

Los factores de riesgo que pueden llegar a desencadenar la muerte precoz son bastante conocidos. Entre ellos la hipertensión y la obesidad parecen los más destacados, especialmente cuando se unen al propio envejecimiento. Distintos autores han demostrado que el ejercicio físico, aun realizado en edades tardías de la vida, resulta igualmente beneficioso para combatir estos factores de riesgo, estando exento de riesgos si se practica de forma adecuada.

Nosotros hemos estudiando los beneficios de un «programa de ejercicio físico y dieta adecuada» en dos grupos de pacientes con edades comprendidas entre los 60-64 y los 65-69 años, sobre factores de riesgo como la hipertensión, la obesidad, el estreñimiento y el insomnio. En conjunto se han obtenido nuevamente resultados que aconsejan seguir su práctica. Sin embargo, parámetros como la tensión arterial diastólica se muestran más difíciles de corregir en el grupo de más edad, mientras que el sobrepeso se corrigió con mayor facilidad en el grupo de más edad.
Una visión neuroanatómica de los ganglios basales con algunas implicaciones en su fisiopatología
Authors: Giménez-Amaya J. M.
Published: October 2022

Los glanglios basales son unas masas celulares subcorticales que engloban fundamentalmente al cuerpo estriado (núcleos caudado y lenticular), al que se unen otras estructuras como son principalmente el núcleo subtalámico y la substancia negra. Un aspecto neuroanatómico destaca en los ganglios basales: su profunda heterogeneidad. Esta heterogeneidad puede observarse con claridad desde tres puntos de vista: hodológico, histoquímico y citoarquitectónico. Este artículo trata de correlacionar esta heteragenidad de los ganglios basales con la fisiopatología de alteraciones profundas de los mismos, como son las que se observan en el hemibalismo y en las enfermedades de Parkinson y Huntington.

Acid resistance of alkali-activated composites containing waste glass as fine aggregate
Authors: Khan Md Nabi Newaz , Elahi Md Manjur A. , Kuri Jhutan Chandra , Sarker Prabir Kumar , Shaikh Faiz Uddin Ahmed
Published: October 2022

This study examined the efficacy of waste glass cullet (WGC) as a substitute for natural fine aggregate in alkali-activated composites when exposed to sulfuric acid and hydrochloric acid solutions for 1 year. The physical appearance, surface alkalinity, mass, mechanical strength and microstructure of hardened samples before and after immersion in acid solutions were investigated. The findings this work indicated that physical, mechanical and microstructural damage of the specimens due to acid attack increased with an increase in the percentage of WGC. This was attributed to the smooth surface texture and angularity of the WGC, which affected the bond with the damaged paste matrix at the interfacial transition zone and increased the porosity. However, the acid resistance of the mortars containing up to 50% WGC was found to be satisfactory when compared with the mortar without WGC. Therefore, the use of WGC as a partial replacement (up to 50%) for natural sand is feasible for alkali-activated systems under acid exposure.
Designing Interventions Addressing Structural Racism to Reduce Kidney Health Disparities: A Report from an NIDDK Workshop
Authors: Crews Deidra , Patzer Rachel , Cervantes Lilia , Knight Richard , Purnell Tanjala , Powe Neil , Edwards Dawn , Norris Keith
Published: October 2022

Structural racism embodies the many ways in which society fosters racial discrimination through "mutually reinforcing inequitable systems" that limit access to resources and opportunities that can promote health and well-being among marginalized communities. To achieve health equity, and kidney health equity more specifically, structural racism must be eliminated. In February 2022, the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK) convened the "Designing Interventions that Address Structural Racism to Reduce Kidney Health Disparities" workshop which was aimed at describing the mechanisms through which structural racism contributes to health and healthcare disparities for people along the continuum of kidney disease; and identifying actionable opportunities for interventional research focused on dismantling or addressing the effects of structural racism. Participants identified six domains as key targets for interventions and future research: 1) apply an anti-racism lens, 2) promote structural interventions, 3) target multiple levels, 4) promote effective community and stakeholder engagement, 5) improve data collection, and 6) advance health equity through new healthcare models. There exists an urgent need for research to develop, implement and evaluate interventions that address the unjust systems, policies, and laws that generate and perpetuate inequities in kidney health.
Reformulating dolus eventualis: Guidance from America and Germany
Authors: Hagglund Kirstin , Khan Franaaz
Published: October 2022

Dolus eventualis has correctly been described as an ‘enigma’. Not only has it been variously described by the courts, but the courts have applied the two-stage test without providing an in-depth analysis of what it means. Both dolus eventualis required for murder and conscious negligence required for culpable homicide, contain an element of subjective foresight of the remote possibility of death occurring. As a result, the distinction between murder and culpable homicide has become confused over the years, and is evident in the courts vacillating between findings of murder and culpable homicide. Considering the lack of clarity, this article examines the test for dolus eventualis in the case of murder and determines whether it can be more clearly distinguished from culpa, in the case of culpable homicide. German and American law and academic opinion is consulted in order to establish how the respective countries have dealt with the conflation of murder and negligent killings.

Biosafety Architectonics
Authors: Galyukova M. I.
Published: October 2022

The paper examines the issues of biosafety as an independent direction of national security. The development of biotechnologies inevitably leads to the emergence of new threats to society and the state, requires a comprehensive study of the current legislation in the field of security. The paper elucidates scientific approaches to the definition of biosafety in a narrow and broad senses. The author notes that the appearance of the official definition of biosafety is a significant step in the development of the system of interdepartmental interaction and an independent direction of national security, but by no means a revolutionary novation. In addition, the paper provides a semantic and meaningful analysis of the concepts of biorisk, biohazard, biological factor, determines the relationship of biological threats and biotechnologies. The paper defines a new independent component of biological safety, namely, genetic safety. The author notes the positive dynamics of biosafety development as one of the directions of national policy and at the same time states obvious legislative and methodological gaps. First, a biohazard is the result of the transformation of a biorisk into a concrete factual circumstance that creates a real danger to human life and health, as well as the security of society, the state and humanity. Second, there is no concept of biotechnologies, their types and classification through the prism of biosafety. Third, genetic safety is an independent component of biological safety. The concept of «genetic safety» should be developed. Fourth, biosafety is an independent vector of the national policy of the state aimed at the effective prevention of biological threats, as well as the development of biotechnologies without risk to human life and health by creating a high-quality legislative framework, an adequate level of law enforcement, the formation of legal awareness and legal culture of the population.
Victimological Factors in Corruption Offences and Anti-Corruption Victimological Security
Authors: Ivanova A. A.
Published: October 2022

The paper investigates victimological factors producing corruption victimization. The research methodology includes a dialectical method of scientific cognition, a systematic approach, analysis and synthesis as general scientific methods for understanding criminological and victimological concepts, private scientific methods: criminal statistical, sociological (survey of convicted respondents — officials), analysis of documents, etc. The empirical base is made up of the results of a criminological study conducted by the author in 2018–2020 as part of an interregional research team (Vladimir, Volgograd, Kazan, Nizhny Novgorod, Syktyvkar), as well as criminal statistics data, materials of judicial practice. To solve the terminological problem, definitions of the concepts «corrupt crime», «corrupt behavior», «corrupt delinquency» are proposed. The author substantiates the application of a systematic methodology for the study of victimological factors as a structural element of corruption offences, their properties, conditions and relationships with other elements. The paper presents the results of a survey involving convicted respondents-officials, and a comparative analysis of judicial statistics data. The author gives a definition of victimological factors of a corruption crime, substantiates their unity with corruption-causing factors, which is manifested in victim-corruption and criminal-corruption behavior, the commission of a corruption crime. It is shown that the corruption crime is based on a corrupt transaction, its concept, characteristics, main elements, content, types are presented. The author shows that any of its subjects can become victims of a corrupt transaction: an official, his counterparty and an intermediary, while victimological factors, levels of victimization and types of victims are presented. It is concluded that anti-corruption victimological security should become a priority area of victimological prevention based on scientific (criminological) support. The expediency of creating (reviving) criminological laboratories on the basis of modern national research universities is argued.
Institution of Preliminary Investigation Suspension: Issues of Theory and Statutory Regulation
Authors: Latypov V. S.
Published: October 2022

The author attempts to analyze the current criminal procedure legislation of the Russian Federation, as well as the system of scientific knowledge available in the theory of criminal procedure law for the need to improve the criminal procedure institution of preliminary investigation suspension. The reliability of the results is ensured by the integrated use of general scientific and private methods allowing formulating an idea of the modern criminal procedure institution of preliminary investigation suspension. The use of the comparative research method allowed the author to conclude that it is possible to implement certain criminal procedural norms of foreign legislation regulating the institution of suspension of a criminal case. The method of historical analysis used in the study allowed us to consider the evolution of this procedural institution and highlight the historical stages of its legal development. The statistical method provides for the study of the suspension of the preliminary investigation based on representative empirical material, which made it possible to identify objective patterns and formulate specific conclusions (it was used when taking into account the results of a survey of citizens). As a result, the author determines the elements inherent in the institution of preliminary investigation suspension and defines the concept. The suspension of the preliminary investigation should be understood as the complex activity of the competent state bodies and officials established by the Criminal Procedure Law, including the adoption of a temporary procedural decision on the suspension of the preliminary investigation, criminal prosecution, the production of procedural actions on the grounds that prevent further criminal proceedings provided for in the law, up to their elimination. According to the author, the main trends in the development of the institution of suspension of the preliminary investigation are: amendment of Chapter 28 of the Code of Criminal Procedure of the Russian Federation, which consists in replacing the phrase «suspension (resumption) of the preliminary investigative activities» with «suspension (resumption) of the preliminary investigation»; expanding the list of grounds for suspending the preliminary investigation; supplementing the criminal procedure legislation with an appropriate norm regulating the prohibition of decision-making on the suspension of the preliminary investigation carried out in the abbreviated form of inquiry; resolution of the issue of the production of investigative actions in suspended criminal cases.
The State as an Indicator of Human Development (With Reference to Neuroscience)
Authors: Kashanina T. V.
Published: October 2022

The paper is transdisciplinary in nature: it is written at the junction of the theory of the state and neurobiology.

   The purpose of the paper is to establish a correlation between the evolution of human consciousness and changes in statehood.

   According to the type of neurobiological processes, people are divided into 4 categories: visual, auditory, kinesthetic and digital. If we group these psychotypes, then the neurobiological characteristic of society will appear as a changing constant of two types of thinking: irrational and rational. The global trend in their ratio is as follows: there is a gradual increase in rational thinking. However, the pace of development of countries varies, and to measure the level of development, the UN uses the Human Development Index (HDI), based on economic and social indicators. The author suggests supplementing the HDI with a political component: a characteristic of statehood, since ignoring this gives an incomplete picture of human development. The main parameters of the state are its type and essence. According to the type of state, they are divided into agrarian, industrial and informational. It is concluded that if in an agrarian state the proportion of people with rational thinking is extremely small, then in an industrial state their number increases, but not enough to make the government controlled by society. In an information state, the government becomes controlled by the people precisely because of the presence of a critical mass of sane people. The essence of the state — its volitional component — has a dual nature: it expresses the interests of society and the ruling elite. This balance again depends ultimately on the level of public consciousness. The pattern here is as follows: at the early stages of the development of society, the state mainly expresses the interests of the ruling elite. Then the share of general social interests gradually increases. At later stages of the development of the state, general social interests begin to dominate in law. Ultimately, the state turns into a «servant» of society, and civil servants, including senior officials, become managers of public administration.

Authors: Navarro-Iribarne Juan Francisco , Moreno-Salinas David , Sánchez-Moreno José
Published: October 2022

El empleo de la monitorización para el análisis deportivo se ha convertido en una herramienta casi indispensable en el entrenamiento profesional de alto nivel. El poder conocer con exactitud los movimientos realizados por un deportista durante un entrenamiento aportan una gran ventaja con respecto al entrenamiento convencional, ya que si se conoce de forma teórica el movimiento que mejor rendimiento ofrece, el entrenador pretenderá que su deportista aproxime su movimiento real al teórico. Este artículo trata sobre el desarrollo de un sistema de bajo coste para la medición y representación de parámetros cinemáticos en 3D. Para la captura de los movimientos del deportista se ha empleado una unidad de medición inercial (IMU), cuyos datos serán procesados en una placa Arduino y mediante Bluetooth se enviarán los parámetros cinemáticos del movimiento a un teléfono móvil donde serán visualizados en forma de gráficas.

Creación y análisis de vistas 360 a partir de un par de imágenes fisheye
Authors: Flores María , Valiente David , Gil Arturo , Reinoso Oscar , Payá Luis
Published: October 2022

Los sistemas de visión conformados por dos lentes fisheye posicionadas de forma que cubran un campo de visión de 360° presentan grandes ventajas, como la posibilidad de obtener una vista 360 de alta calidad, que puede ser usada en otras tareas de alto nivel. Haciendo uso de una cámara comercial de este tipo, el principal objetivo del trabajo consiste en el desarrollo de métodos para la obtención de una vista 360 y la evaluación de la calidad de la misma, comparándola con la vista 360 generada por la propia cámara. Inicialmente, el algoritmo realiza una proyección de cada imagen fisheye a formato equirectangular, lo cual facilita el posterior stitching necesario para componer la vista 360. Para ello, se han implementado dos procedimientos que permiten realizar la proyección sobre la esfera unidad. Con objeto de determinar automáticamente la calidad de la vista 360 obtenida, y así poder compararla con la generada por la propia cámara, se propone un algoritmo basado en una red neuronal convolucional que extrae descriptores de apariencia global de las escenas. La comparación entre descriptores permitirá determinar la calidad relativa de la vista obtenida. Los resultados muestran que, en aquellos casos en los que la zona de solape es rica en información visual, una de las imágenes que generamos es mejor que la proporcionada por la cámara.

Published: October 2022

Las afecciones por parásitos intestinales son un grave problema de salud con un alto impacto en algunas áreas geográficas. Dado que actualmente la evaluación de estas enfermedades se realiza de forma manual a través de expertos, es posible aplicar técnicas de aprendizaje automático para ayudar en el desarrollo de esta tarea, reduciendo al menos la carga de trabajo. Esto podría llevar a un menor tiempo de detección de la enfermedad y a la aplicación de un tratamiento adecuado más rápidamente. En el contexto del aprendizaje profundo, se han propuesto muchas técnicas de detección de objetos, validadas en conjuntos de datos de propósito general, como ImageNet o COCO. En este trabajo, proponemos una unión de varias de ellas, incluyendo técnicas recientes basadas en Transformers, para afrontar esta tarea particular. Como resultado, la unión de los métodos TOOD, Cascade-RCNN (Swin-Transformer), Cascade-RCNN (ConvNeXt) y YOLOX, aplicados a la detección de este tipo de imágenes, consigue un valor de 0,915 para la métrica Intersección sobre la Unión (Intersection over Union, IoU), el cual es mayor que los resultados obtenidos por cada uno de los métodos por separado.

Published: October 2022

El nivel de precisión de las redes neuronales profundas en tareas de percepción visual permite captar información crucial del entorno para futuros proyectos, como los vehículos autónomos y las ciudades inteligentes. Una de las posibilidades que permitiría este tipo de sistemas es el control y seguimiento de determinados vehículos sospechosos. Teniendo en cuenta el uso de esta tecnología por parte de la policía, se facilitaría el seguimiento de determinados coches bajo investigación. Con esta visión, el objetivo de este trabajo es el estudio del estado del arte actual de los métodos y el desarrollo de un sistema que resuelva dos tareas de forma eficiente: la caracterización visual y reidentificación de vehículos y la segmentación de matrículas y reconocimiento de caracteres. Esta doble identificación puede adaptarse a las condiciones ambientales, a la distancia del objetivo y a las capacidades y resolución de las cámaras. Para probar y validar este sistema, se ha creado un conjunto de datos personalizado para minimizar la diferencia entre el laboratorio y el entorno real.

Transforming the Self, Family and Society through a Qur’anic Ethos
Authors: Alwani Zainab
Published: October 2022

This article examines how the Qur'an transforms self, family and society; discusses oppression of oneself and others; and demonstrates how the problems it causes can be prevented by constant self-awareness and self accountability. In addition, it addresses various issues including the Qur’an’s view of oppression’s spiritual roots, the origin of human relations, and taqwā’s relationship with self-development. In addition, and most importantly, it identifies the oppressor and the oppressed; explains how oppressors can transform themselves; why God holds people accountable; and how to evaluate our strategies’ success or failure in dealing with oppression. The methodology used is that of reading the Qurʾan intra-textually as one structural unity (al waḥda al-binā’iyya li-l-Qur’ān). This involves cross-examining and integrating the sacred text’s linguistic, structural, and conceptual elements. The overarching goal of this approach is to prevent injustice and promote peace through justice, mercy, and mutual accountability.
The Role of Muslim American Nonprofits in Combating Domestic Violence in the Community: An Exploratory Overview
Authors: Siddiqui Shariq , Noor Zeeshan
Published: October 2022

Domestic violence, misogyny, and patriarchy have long been a challenge for society. In fact, one of the first realities confronting Prophet Muhammad was the inequity and inequality of women, orphans, and the vulnerable. This resulted in the forbidding of killing female babies and giving women the rights to decide who to marry, request a divorce, and own property – instead of being property – and much more. Many of the Prophet’s words and actions (the Hadith and Sunnah) are known to us today because of the memories shared by his wife Aisha. The fact that she became such an important keeper of this tradition and that her memories required no corroborating witness suggest the important role she played in early Islamic society. The Prophet’s first supporter and convert was his first wife Khadijah. One of the wealthiest entrepreneurs of her time, she provided the financial independence for the development of the Islamic faith. Both of them play critical roles in Islam’s establishment and eventual dissemination. They are beloved by Muslims, but the fact that they are women and leaders has not been institutionalized.
Despite these revolutionary reforms, humanity’s failure to continue them has led societies, families, and social structures to find ways to control women and further strengthen existing patriarchal societies. One component of this social control is domestic and sexual violence within existing familial structures.
This article seeks to place the efforts of the Islamic Society of North America (ISNA) to fight domestic violence in the Muslim American community from 1997 through 2005. In addition to examining the society’s annual reports and Islamic Horizons magazine, it draws on the coauthors’ embedded experience. It first examines the literature associated with religiosity, Islamic perspectives on domestic violence, Muslim Americans, and Muslim Americans and domestic violence. The article then undertakes a case study of ISNA from 1997 to 2004 and concludes with recommendations for future research.
Government Reporting and Quality of Public Services: Are They Twins?
Authors: Pertiwi Puspa Kusuma , Wibowo Puji
Published: October 2022

Research aims: This study aims to analyze the effect of audit findings and audit recommendation follow-up on the quality of public services through the quality of financial reports.Design/Methodology/Approach: This study employed cross-sectional regression using data from 170 observations of 34 ministries and institutions in Indonesia for the 2015-2019 period by adopting a purposive sampling method. Hypotheses testing was performed using binary logistic regression analysis, multiple linear regression, and path analysis.Research findings: The results showcased that the audit findings negatively impacted the quality of financial reports, while audit recommendation follow-up did not affect the quality of financial reports. The audit findings also did not influence the quality of public services, while audit recommendation follow-up led to better public services.Practical and Theoretical contribution/Originality: Central government institutions are expected to improve the effectiveness of the internal control system and compliance with laws and regulations in managing state finances to create more quality and reliable financial information. These institutions are also encouraged to overcome non-tax revenue irregularities to promote good governance in public service. The study provides empirical evidence regarding the determinants of public service quality by developing new measurements associated with the characteristic of non-tax revenue imposed by the line ministries and agencies.Research limitation: Future research is needed to develop the quality of public service indicators with other indicators and consider using primary data through a questionnaire survey to measure the quality of public services.

A Educação Profissional e Tecnológica e a Aprendizagem Baseada em Problemas no Ensino Híbrido e a Distância: uma Revisão Sistemática
Authors: Cordova Paulo Roberto , Garcia Cristiano Mesquita , Vicari Rosa Maria
Published: October 2022

As Tecnologias Digitais de Informação e Comunicação (TDIC) têm oportunizado melhorias e aumento na oferta de Educação a Distância (EaD). A Aprendizagem Baseada em Problemas (PBL) vem se mostrando efetiva, principalmente por propiciar a aproximação do estudante com situações reais vividas por profissionais, característica importante para a Educação Profissional e Tecnológica (EPT). Na literatura vigente não há dados sobre o quanto a PBL tem sido aplicada à EPT por meio da EaD ou do ensino híbrido. Esta pesquisa, por meio de uma revisão sistemática, visa preencher esta lacuna. Evidenciou-se que há poucas publicações sobre este tema, deixando aberta a questão sobre se isso se deve à baixa adesão à PBL ou se as experiências e investigações neste campo não têm sido amplamente divulgadas.

IGBT Wirebonds Ageing: A New Test Bench Development for Dedicated Modules Assemblies
Authors: Pellecuer Guillaume , Huselstein Jean-Jacques , Martiré Thierry , Forest François , Chrysochoos André , Jebli Mourad
Published: October 2022

Wirebonds ageing in power modules used in electric vehicles is a main concern for the development of reliable inverters. The development of a specific test bench to study the evolution of their properties over time has allowed conclusions to be drawn on the possibility of accelerating or not accelerating ageing tests without distorting the mechanisms actually involved in ageing. Through the use of specifically developed test bench in terms of electrical and thermal properties the studied wirebonds samples are more easily thermally controllable, equipped with measuring devices and the energy consumption at a given cycle is divided by ten compared to a classical bench. The entire process of designing and producing the specific samples and the associated test bench and a description of the first results obtained to demonstrate the relevance of the approach is given.
Ultrasonic Velocity and Critical Micellar Concentration of Glycerol Monostearate in Mixed Organic Solvent at 290 K

Published: October 2022

Density, viscosity, ultrasonic velocity and refractive index measurements of Glycerol Monostearate (GMS) in 80/20 (% v/v) benzene-methanol mixture at 290 K with varying concentrations have shown that there is noticeable variation in aggregation of non-ionic surfactant at Critical Micellar Concentration (CMC). Density and viscosity results have been satisfactorily explained by some well-known equations viz. Jones-Dole, Moulik, Vand, Einstein and Root. Jacobson model has been used to evaluate adiabatic compressibility, molar compressibility, solvation number molar sound velocity, relaxation strength, relative association and other allied acoustical constants. The variation of refractive index with concentration of GMS solutions shows a marked change in value at CMC. Treatment of data obtained from density, viscosity, ultrasonic velocity and refractive index measurements has shown that strong interaction exists between GMS and solvent molecules, and GMS molecules do not aggregate considerably in pre-micellization region.
Study on Hardness and Microstructural Properties of Ti-6Al-4V Alloy using Overlapped Multipass Laser Transformation Hardening under Optimized Test Conditions
Authors: Sawant Badkar Duradundi
Published: October 2022

In this research paper, overlapped multipass Laser Transformation Hardening (LTH) of Ti-6Al-4V titanium alloy sheet of 2 mm thickness was analyzed experimentally for uniformly intense, CW spherical beam moving with constant speed using 2 kW Nd: YAG laser. Experiments were conducted for optimized two sets of laser process parameters: 1. High Laser Process Parameter (HLPP), Lp = 800 Watts, Ss = 3000 mm/min, Fp = -10 mm, with heat input 180 J/cm and 2. Low Laser Process Parameter (LLPP), Lp = 600 Watts, Ss = 2000 mm/min, Fp = -10 mm, with heat input 160 J/cm respectively having same Fp = -10 mm. The maximum, minimum and average hardened depths of 0.27, 0.19 and 0.23 mm respectively, achieved for HLPP were found to be minimum, as compared to the maximum, minimum and average hardened depths of 0.38, 0.29 and 0.33 mm, respectively, for LLPP. Measurements of Vickers micro-hardness survey of the hardened zone of the laser processed Ti-6Al-4V alloy are presented. Vickers micro-hardness of an as-received two-phase (Î±+Î²) Ti-6Al-4V titanium alloy is 328 HV. The results showed that Vickers micro-hardness on top of the surface (TS), in hardened or fusion zone (Fz), at the interface of Fz -Haz, in the heat affected zone (Haz) is higher than the bulk material. The high hardness values of 450 HV and 445 HV were investigated on the top surface for high and low laser process parameters respectively. This can be the quality characteristics of the dissolution of small amounts of oxygen, nitrogen, and carbon with hard martensite Î±' (transformed Î²) formation, thereby ensuring an increase in wear resistance of laser treated hardened surface of Ti-6Al-4V considerably in relation to the untreated or base alloy.

Published: October 2022

Present work evaluates the ability of Aspergillus oryzae and commercial dry Baker's yeast to effectively remove Cu2+ ions from aqueous solutions. Batch experiments were carried out in order to analyze sorption behavior of metal-sorbent system at different biosorbent dosage, and initial metal concentration. Various pre-treatment methods were adopted to modify the biomass, and effect of pre-treatment was investigated on biosorption efficiency. Till now, very few efforts are dedicated for application of immobilized biosorbents in literature therefore further investigations were done on the biosorption efficiency of biomass immobilized in a natural matrix which might augment stability, mechanical strength, and reusability of the biomass. Approximately 86 and 95% biosorption of copper was attained under optimum reaction conditions using Loofah immobilized with Baker's yeast, and A. oryzae, respectively. Desorption efficiency of the immobilized biomass was evaluated by performing successive biosorption-desorption cycles. Successful regeneration of Loofah sponge loaded with immobilized biosorbent was illustrated by desorbing more than 95% copper. Characterization studies were performed to examine the changes in surface morphology, and surface chemistry before and after adsorption.
Centenary of Langmuir Isotherm

Published: October 2022

Irving Langmuir published a seminal paper, on the adsorption of gases at a constant temperature in 1918, which presented one of the most important isotherm equations available in post Langmuir era. Many other useful isotherm equations were suggested both before and after 1918. The 1918 equation was the first where a model for adsorption phenomenon was suggested. In this article, we present a reasonably coherent discussion on Langmuir and some other adsorption isotherms reported in literature focusing on their uses and applications as well as analysing the merits and demerits to commemorate the hundred years of Langmuir's pioneering contribution in surface chemistry.
Development and Characterisation of W and W-25% Ta Composite Coatings on Steel Material

Published: October 2022

Nanostructured Tungsten (W) and Tungsten-Tantalum (W-25% Ta) thin films are generated on Reduced Activation Ferritic Martensitic (RAFM) steel substrates. The developed thin films are then analysed for their adhesive strength, hardness and elastic modulus properties. The addition of Tantalum by 25% as a composite material in Tungsten thin-film coating has increased the ductility and decreased the hardness of the film at room temperature condition. Tantalum addition has decreased the adhesion capability of the Tungsten film to the steel substrate. In this study, adhesion analysis is qualitatively assessed by indentation test, and hardness along with modulus are calculated using nanoindentation test.
