Comparison of Numerical Methods for Thermal Performance Evaluation of Circuit Protection Devices in EV Application
Authors: Avadhoot Kittur  , Dikhsita Choudhary  , Dr. Robert Michael Slepian
Published: June 2022

With the growing demand of electric vehicles, design of circuit protection devices is now an important consideration in automobile industry. Modern day circuit protection devices have been constantly undergoing miniaturization due to requirement of minimizing the foot print for use in electrical vehicles and aerospace applications. This size reduction makes thermal management one of the most important aspects of their design. Use of numerical model to predict heat transfer can significantly reduce the cost and time required in testing physical prototypes. In this paper, three different approaches for numerically predicting temperature rise of circuit breakers are discussed and compared from the point of view of accuracy and computational effort. The three methods are 1) Finite volume based analysis in which conjugate heat transfer inside and outside the breaker is modelled by solving Navier-Stokes equations 2) Finite element based heat conduction model in which convection is modelled as boundary condition instead of solving for fluid motion, and 3) Thermal network based model which uses electrical analogy of heat transfer to solve a thermal resistance network. In the first two iterative models mentioned above, heat generation from current-carrying parts is calculated by solving Maxwell’s equations of electromagnetics by Finite element method. Eddy current losses and temperature dependence of electrical conductivity is considered in the calculation of heat loss. In all three methods, electrical and thermal contact resistances are added at appropriate locations based on analytical calculations. All three methods have been validated with temperature rise test results. In this paper, the heat loss and temperature of a molded case circuit breaker have been predicted by all three methods discussed above. It is observed that the Finite volume-based method is the most accurate amongst the three methods. It can computationally predict air motion and air temperature at critical locations. However, this additional accuracy comes at the cost of added effort in terms of additional mesh count and computation. The Finite elementbased method gives good accuracy but does not predict air temperature. The analytical network-based model is less accurate compared to other methods and relies on product expertise and experience. Based on the study, the following recommendations are made:1) The finite element-based method is best suited to evaluate designs which do not alter flow pattern significantly 2) The finite volume method is recommended to evaluate effect of flow altering design changes 3) The network-based model is recommended for initial evaluation of correct cross sections of current carrying members.

Authors: Ramadurg Bandenawaz , Jat Rakesh Kumar , Badami Shrishailappa
Published: June 2022

Objective: Careya arborea bark is known for its cytotoxic, antioxidant and anticancer activities. However, the root has not been studied so far for its biological properties. Preliminary studies carried out by us indicated strong cytotoxic and antioxidant effects in vitro of the crude methanol extract of its root. Hence, in the present study, the root extract was examined for its solid tumour inhibition properties in DLA induced mice. 

Methods: The root was collected and extracted with methanol by the Soxhlet method. The mice were divided into five groups comprising normal, positive control, standard and extract at two doses. The methanol extract of the root at the doses of 50 and 100 mg/kg body weight was given to DLA induced solid tumour in mice. The treatments were given for 14 days and the anti-tumour, haematological and biochemical estimations were carried out.

Results: The methanol extract at both doses significantly inhibited the increase in solid tumour weight, reversed the biochemical and Haematological parameters affected by the DLA towards the normal indicating its anti-tumour nature. The microscopic observations of the sections of the liver of treated mice also indicated the activity. However, the activity was found to be less than that of the standard.

Conclusions: The study confirms that like its bark, the root also possess the anti-tumour activity and probably the whole plant may possess anti-tumour active necessitating the need to isolate its active constituents.

Authors: Bič Martin
Published: June 2022

Nowadays, entrepreneurs can very easily find themselves in a bad financial situation. That is why it is essential to look for ways to help them effectively. However, this cannot be done without knowing the real situation in each country, which is the basis for creating the appropriate conditions. The study's main objective was to identify and compare the development of insolvency indicators representing the bankruptcy of entrepreneurs in Slovakia and the Czech Republic from the first quarter of 2017 to the second quarter of 2021. Descriptive analysis and primary research methods were used to achieve this objective. The analytical processing dealt with the indicator of initiated bankruptcies. A fluctuating decline was observed in both countries. In 2020, a slight increase was recorded, and a further increase can be expected due to the coronavirus disease 2019 (COVID-19) pandemic. 2018 and 2017 were the least positive years for Slovakia and the Czech Republic, respectively. The results indicated the need for interventions in the business environment of both countries to help entrepreneurs in bad situations.

Authors: Kolková Andrea , Rozehnal Petr , Gaži Filip , Fajmon Lukáš
Published: June 2022

The purpose of the study is to evaluate the use of quantitative methods in companies and determine the reasons for the non-use of quantitative methods. First, the context of dependence on individual characteristics of the company, such as size, amount of foreign share, and business sector, is analysed. Subsequently, the methods companies use, and those for which companies require scientific support and research are identified. The study is carried out in companies in the Czech Republic and is based on an electronic survey. Methods of statistical testing of dependencies are used for evaluation. The inputs showed that the size of the company is the most dependent on the use of quantitative methods in companies. From the results of the question on the reasons for not using quantitative methods in business practice, the most significant number of respondents answered that the methods are too academic and often their use in business practice is unrealistic due to their complexity. It is the trend of academic institutions and scientific societies to develop quantitative evaluation software with simple input and interpretation. They identified the forecasting of business variables as the method with the greatest scientific potential. The following are simulation methods and logistics management methods. The article may provide a central theme for future science and research development in business.

Authors: Andhika Saputra  , Mochamad Isyn Winandi  , Edi Suharto
Published: June 2022

This study aims to analyze, design, and build an information system at POS SPP Bandung. The authors obtained the necessary data using observation, interviews, and literature studies from several previous studies. Based on employee observations and interviews, the system in POS SPP incoming division was less efficient, because it took two employees to run the item scan system. The goal to be achieved is that the information system that we have designed can help the process of receiving goods or items to be more accurate and faster. And as it only requires one employee to carry out the process of receiving goods, making it more effective and efficient. Therefore, in this study, an Android-based item input information system design was made using UML and implemented with the Java programming language and MySQL as a database and quick response code feature for the scanning process.

Authors: Aris Sulistiyanto  , I Nyoman Sudana Degeng  , Nurmida Catherine Sitompul
Published: June 2022

The students of grade XI of the Motorcycle Business Engineering of Vocational High School, who have learned productive subject matter in Motorcycle Engineering and Business, often experience difficulties when directly confronted with motorcycle practice media because the components are closed and hidden by the motorcycle's body cover. Therefore, a learning media which is easy to be learned by the students is essential. It means that all components can be observed clearly, and the material can be understood easily, both in theory and electrical practicum of the motorcycle starter system; the students will better understand the theory and assemble the motorcycle starter system circuit. The learning media for the motorcycle starter system is an electrical board with LEDs that can light up continuously or alternately, so it simulate the workings of the motorcycle starter system. In addition, the running LED simulation makes it easier for students to assemble a starter system. It also makes it easy and fast for students to identify, understand how it works, assemble a motorcycle starter system, and later, when facing practical materials in the form of motorbikes, students will be quicker to apply the material that they acquired from the learning media, so that, in practicum, students will work faster and minimize damage to motorcycles.

Authors: Trisna Wati  , Dany Arianto  , Santi Triwijaya
Published: June 2022

The disturbance of transformers often occurs at the field is named partial discharge. It refers to the spark release in the isolation of internal cavity or surface caused by the potential difference in the transformer isolation. As a result, the quality degradation of isolation material happens. To test it, the researcher employed Dissolved Gas Analysis by Roger's Ratio and Duval Triangle methods. The results demonstrated that transformer GT 10 reached the highest temperature of 417,229⁰C and produced overheating as indicated by paper carbonation and carbon particle formation in the oil (thermal fault 3000C–7000C). Meanwhile, the GT 20 transformer achieved the highest temperature of 169.2307⁰C and the color of paper isolation change to brown (at <300°C). Both transformers were detected getting the failure of partial discharge as the temperatures were more than 150⁰C; in which several gases were formed, including hydrogen and methane gases at around 150⁰C, ethane gas at approximately 250⁰C, ethylene gas at about 350⁰C, and acetylene gas at around 700⁰C. Accordingly, the higher the temperature, the lower the dielectric capacity, where it should function for separating the electrical conductors.

Authors: Fernández Daniel , Pujol Clara , Ruber Carmen , Calvo Sandra , Levin Mindy F. , Herrero Pablo , Gómez-Trullén Eva María
Published: June 2022

Stroke is one of the most common causes of disability and exerts a high burden of direct and indirect costs. Stroke may cause spasticity, which limits patients’ abilities and affects their activities of daily living, decreasing their quality of life. Conventional treatments are based on physical therapy, anti-spasticity medication, and botulinum toxin type A (BTX-A). However, recently, non-pharmacological approaches have been used, such as dry needling (DN) of myofascial trigger points. BTX-A and DN are two treatments that aim to decrease spasticity in patients with stroke, but their mode of action, application, and costs differ. Thus, there is a need to determine the comparative economics of post-stroke spasticity treatments. For this purpose, a search for all types of cost-effectiveness studies (randomized controlled trials, matched controls, and cohorts) and models of epidemiological data was performed. Studies were selected if they included economic outcomes in stroke patients treated with BTX-A or DN. As a result, 7 studies of BTX-A and 2 of DN were selected. Similarities were found in the outcomes used to assess the effectiveness of both treatments in most studies, with modifications of the Ashworth Scale [Modified Ashworth Scale (MAS)/Modified Modified Ashworth Scale (MMAS)] and quality-adjusted life year (QALY) being the main indicators of effectiveness. However, both the duration of the studies and the evaluation of costs were highly heterogeneous, making comparison difficult. In conclusion, both BTX-A and DN are cost-effective to treat spasticity in patients with stroke, but there is a need for comparative studies to make direct comparisons of cost-effectiveness with the most frequently used outcomes such as the MMAS and QALYs.

Published: June 2022

This paperwork is aiming to describe the business model for a bunkering process as part of the supply chain network from a Company in Constanta port. The authors have conducted a study of modelling the bunkering process for a ship from the company's fleet, which is moored in the port of Constanta, using the Business Process Modelling tools and methodology. The bunkering process with all its stages will be incorporated in the AuraPortal Helium Modeler program and statistically simulated. This entails putting processes through their paces in fictitious scenarios to discover and quantify any factors that might influence how they are carried out in real life. Bottlenecks, overloads, uneven workload distribution, unnecessary time, expenses, and other issues should be revealed by these activities. The authors will do an actual simulation of the bunkering process in the concluding remarks to reflect the process dynamics issues experienced during the full life cycle.
Cuestiones probatorias en el Litigio de Interés Público. Sobre la prueba de la violación de los derechos sociales
Authors: Ucín María Carlota
Published: June 2022

Los litigios que procuran la vigencia de los derechos sociales pueden hallar dificultades para probar los hechos que los sustentan. Esto se puede explicar, entre otras razones, por la indeterminación de los enunciados normativos y por la asimetría en el acceso a la información pública. Como aquí se analizará, el recurso a las presunciones puede allanar las dificultades probatorias, con un claro beneficio sobre el acceso a la justicia para este tipo de causas.
Online dispute resolution for small claims: is this the only realistic solution?
Authors: Nieva-Fenoll Jordi
Published: June 2022

Some jurists believe that the judicial process is not adequate for these lawsuits when they are transnational, but in fact, neither is it when they are national. It is true that a transnational claim is challenging in terms of applicable law, the search for national lawyers, the search of evidence and even the translations. But actually all inconveniences are based upon a very old mentality linked with the also very old ‘de minimis non curat praetor’. Whoever thinks that dealing with transnational small claims is not really feasible, does not see how to deal with them adequately in domestic law either. These authors also think that the resolution of small claims should be transferred to mediation –often useless–, to consumer arbitration, whose institutional development as parallel to state justice is extremely complicated, or even to collective redress, although in the vast majority of cases there is not really a group of stakeholders that can be managed together. Furthermore, organizing this kind of collective redress is very difficult. It’s maybe necessary to remember that class-actions in the US almost never reach the trial phase.

Authors: Simaitis Rimantas , Vėbraitė Vigita , Markevičiūtė Milda
Published: June 2022

In this article, the European Small Claims Procedure will be analysed in the context of the other European procedures, namely Brussels I bis Regulation (Regulation (EU) No 1215/2012), European Enforcement Order Procedure, European Payment Order Procedure and Consumer ODR Procedure. The aim of each procedure, their benefits for users and drawbacks are compared in order to establish the areas in which the European Small Claims Procedure can be improved or modified contributing better towards the development of more efficient and user-friendly European Union civil proceedings system. Results of the SCAN | Small Claims Analysis Network consortium studies of the application of the ESCP are used as a basis of this article. The article among other issues will cover premises to introduce seamlessly integrated dispute resolution methods and tools in the European Small Claims procedure such as early-diagnostics, negotiations, mediation, etc. in order to create a pyramid-shaped dispute resolution system so that only the disputes that cannot be resolved by using other tools would be channeled to the adjudicative stage.
Oral hearing management Under the E.S.C.P. Regulation
Authors: Turroni Davide
Published: June 2022

The ESCP is featured as a written procedure, wherein the oral hearing is granted limited space. The reason stems from the fact that oral hearing in cross-border litigations takes significantly longer time and its worth seems to be – notably in civil matters such as those included in the ESCP scope – inversely related with the case value (the smaller the value, the lesser the worth). Such a discipline gives rise to a number of significant issues, concerning its consistency with the procedural fundamental «right to be heard»; the correlative margin of discretion the court may rely on in deciding whether a hearing shall be scheduled or not; not least the role played by the modern communication technologies in this respect. The Author deals with such issues in their multiple features and connections, trying thence to offer proper answers thereto. The overall Author’s view is that the ESCP Regulation’s restrictive approach to oral hearing is reconciliable with the right to be heard and that the broad discretion conferred to the court in this respect is justified as well.
español como lengua comunitaria y lengua de herencia en Quebec
Authors: Pato Enrique
Published: June 2022

Este trabajo ofrece un panorama abarcador de la situación del español como lengua comunitaria y como lengua de herencia en la provincia de Quebec, con especial relación a la Región metropolitana de Montreal, espacio geográfico que concentra el mayor número de hispanos de todo el país. Para ello, se presenta la influencia de las lenguas mayoritarias (francés e inglés) y algunos de los rasgos gramaticales y léxicos de contacto tanto en el habla de los jóvenes como en la de los hablantes adultos. Por lo que respecta a la conservación del español como lengua de herencia, existe una multitud de factores implicados, a pesar de la falta de una “política lingüística” explícita en el hogar. Por último, se analiza un caso concreto de transferencia lingüística directa del francés: el uso de mismo si (‘aunque, incluso si’) como elemento estructuralmente compatible que se registra en el habla de todos los inmigrantes.
Valores sociales del español en el contexto de su enseñanza como lengua de herencia La Escuela Latinoamericana de Berna
Authors: Buerki Yvette
Published: June 2022

El objetivo de esta investigación sociolingüística de corte etnográfico radica en observar y analizar cuáles son los valores sociales que adquiere el español como lengua de herencia en una institución dedicada a su transmisión. El análisis de los datos recogidos muestra que la transmisión del español como lengua de herencia está vinculada de forma estrecha con los diferentes valores sociales que se le confiere y que van desde la adscripción étnica hasta el valor utilitario del español como soft skill en un mundo altamente globalizado y donde las posibilidades de empleo se encuentran hoy en día primordialmente en el sector terciario de servicios.

Esta investigación es de importancia para los estudios sociolingüísticos, en especial para aquellos sobre Lengua de Herencia, porque dichos estudios siguen siendo escasos en los países europeos. Por ejemplo, en el caso del español, los pocos estudios realizados en Suiza se centran en el aspecto adquisicional y el desarrollo de las destrezas bilingües.

In the Barents Sea, the major part of the annual primary pelagic production is formed during the spring phytoplankton bloom. A phytoplankton bloom is understood as an annually recurring increase in its total biomass. Chlorophyll a concentration reflects changes in phytoplankton biomass and can serve as an indicator of production characteristics. In April 2021, the thermohaline characteristics of the water column and the distribution of chlorophyll a concentrations along a standard transect “Kola Section” were studied. The Transect was located in the path of the warm waters of the Nordkapp current and the desalinated waters of the Murmansk coastal current. Coastal, Atlantic and Arctic waters were defined along the Transect. Chlorophyll a concentrations in coastal waters varied on average from 0.57 to 0.86 mg/m3 (maximum 1.11 mg/m3), in Atlantic waters from 0.11 to 0.34 mg/m3 (maximum 0.50 mg/m3). At the station located in the area of intensive interaction of two types of waters (in the area of salinity and temperature fronts) maximum concentrations of chlorophyll a (0.96–1.39 mg/m3) were noted. The location and extent of zones of increased (or decreased) chlorophyll a concentrations agreed with the alternation of water masses. The beginning of the early spring phytoplankton bloom was in the coastal zone of Central Murman.

Published: June 2022

Penelitian ini bertujuan mendeskripsikan kompleksitas konflik Ukraina-Rusia sejak tahun 1991 sampai sekarang. Penelitian ini menggunakan metode sejarah yang terdiri dari empat langkah yaitu mengumpulkan data atau heuristik, kritik sumber atau verifikasi, penafsiran sejarah atau interpretasi dan penulisan sejarah atau historiografi. Hasil penelitian menyimpulkan bahwa konflik Ukraina-Rusia telah berlangsung sejak tahun 1991. Paska runtukhnya Uni Soviet, Ukraina menolak dominasi Rusia dalam Commonwealth of Independent States (CIS) maupun Eropa Timur dan memlih bergabung dengan Uni Eropa (UE). Konflik Ukraina-Rusia kemudian berlanjut pada tahun 2013 yang diawali krisis ekonomi Ukraina dan pencopotan Yanukovych yang pro Rusia dari kursi kepresidenan dan digantikan oleh presiden yang pro Barat-NATO. Hal ini menyebabkan beberapa wilayah yang pro Rusia seperti Luhank, Doneks dan Crimea mulai bergejolak dan menyatakan diri bergabung dengan Rusia. Pemerintah Rusia di bawah Putin merasa terancam baik dalam aspek ekonomi, politik maupun militer apabila Ukraina bergabung dengan Barat-NATO. Putin menyampaikan proposal jaminan yang mengikat secara hukum bahwa aliansi militer NATO akan menghentikan aktivitas militer apa pun di Eropa Timur dan Ukraina. Usulan tersebut ditolak oleh Amerika Serikat (AS). Atas penolakan tersebut, Vladimir Putin pada 24 Februari 2022 mengumumkan bahwa Rusia telah membuat keputusan untuk melancarkan "operasi militer khusus" di Ukraina Timur.

Although the development of upper abdominal metastases in relapsed ovarian cancer has been considered as a sign of biological aggressive disease once the surgical techniques improved these extended resections have been successfully implemented in the armamentarium of cytoreductive surgery. Case: a 54 year old patient diagnosed with an isolated metastasis at the level of upper abdomen invading the pancreatic head, the portal vein and the common hepatic artery was submitted to surgery. Venous reconstruction was performed by using a Goretex patch while arterial reconstruction was performed by using a saphenous graft which was placed between the celiac trunk and the proper hepatic artery. Conclusion: extended local visceral and vascular resections might be needed in order to achieve complete cytoreduction for relapsed ovarian cancer.

Regional air pollution is affected not only by local pollution emissions but also by the trans-regional transportation of pollutants in adjacent areas. To explore the potential contribution source area of atmospheric particulate matter affecting Beijing, based on the Global Data Assimilation System of the National Centers for Environmental Prediction (December 2016 ~ November 2021), this study uses the Hybrid Single-Particle Lagrangian Integrated Trajectory model to cluster the 72-hour backward airflow trajectory arriving in Beijing by season. Combined with the ground observation data of PM2.5 and PM10 mass concentration, the spatial characteristics of different traffic routes in Beijing and their contribution to the accumulation of PM2.5 and PM10 concentration are analyzed by using the Potential Source Contribution Function and the Concentration Weighted Trajectory, which provides a reasonable theoretical basis for the coordinated treatment of regional air pollution. The results show that the distribution of potential contribution source areas of PM2.5 and PM10 in Beijing has obvious seasonal characteristics, and the concentration contribution of different transportation routes is significantly different. In winter, the distribution of potential source areas shows a trend from northwest to Southeast, which forms a conveyor belt from central Inner Mongolia of China to Beijing through Zhangjiakou of Hebei Province. The high concentration contribution areas of PM2.5 and PM10 are concentrated in the urban area of Beijing, Baoding of Hebei Province, and the west of Tianjin. In spring and autumn, the potential source areas are distributed from south to north, which mainly cover the central part of Hebei Province and the urban area of Beijing. The high concentration contribution areas of PM2.5 and PM10 are smaller than those in winter, and are dotted in Baoding, Shijiazhuang and other places of Hebei Province.

Purpose: Conventionally fractionated radiotherapy (CRT) is widely applied for the treatment of high-risk prostate cancer. Pelvic node irradiation improves control of the disease. Although the therapeutic guidelines support the use of hypofractionated and accelerated radiotherapy (HypoAR), this is addressed to prostate and seminal vesicles. At the same time, the safety and efficacy of HypoAR for pelvic node irradiation remain obscure.Material and Methods: In a phase II study, we evaluated the feasibility of pelvic HypoAR in 22 high-risk prostate cancer patients. The RT scheme delivers 14 consecutive fractions of 3.67 Gy (total 51.38 Gy) to the prostate, 3.5 Gy (total 49 Gy) to the seminal vesicles, and 2.7 Gy (total 37.8 Gy) to the lymph nodes, using image-guided volumetric modulated arc therapy. A comparative radiobiological analysis of dose-volume histogram is performed (HypoAR vs. hypothetical equivalent CRT regimens, without and with time correction).Results: Our clinical experience shows impressively low early and short-term late toxicities, without any grade III events, within a median follow-up of 30 months. Only one biochemical relapse was recorded 30 months after irradiation. In radiobiological analysis, considering an α/β-value of 4 Gy and a λ-value of 0.2 Gy/day for late effects, all comparisons predicted significantly lower toxicity for the HypoAR regimen (p < 0.05). For early toxicities (α/β = 10 Gy), a λ-value lower than 0.4 Gy/day favors the HypoAR regimen, which is along with the clinical results.Conclusion: Radiobiological analysis favors HypoAR as a safe and effective regimen for high-risk prostate cancer patients, which is confirmed in the current phase II clinical study.

DNA barcodes provide a reliable and efficient solution to resolving cryptic species complexes and accelerate species discoveries. The superfamily Ceraphronoidea (Hymenoptera) is a group of parasitoid wasps for which a barcoding approach could be of great help, if it were not for the very poor results. The inability to obtain barcodes for the majority of treated ceraphronoids halts progress on the taxonomy of this hyperdiverse parasitoid group. We here present a working protocol for the barcoding of ceraphronoid wasps which yields a first-time over 90% success rate.
