Background:

Carotid atherosclerosis is associated with cognitive impairment and dementia, though there is limited evidence of a direct link between carotid disease and amyloid-β (Aβ) burden.

Objective:

We studied the association of baseline and progressive carotid intima media thickness (CIMT) with Aβ on 11C-Pittsburgh Compound B (PiB) to determine if those with carotid atherosclerosis would have higher Aβ burden.

Methods:

We studied 47 participants from the Framingham Offspring cohort with carotid ultrasounds measuring CIMT at their 6th clinic examination (aged 49.5±5.7 years) and an average of 9.6 years later, and PiB imaging measuring Aβ on average 22.1 years post baseline. We used multivariate linear regression analyses to relate baseline, follow-up, mean, and progression of internal carotid artery (ICA) and common carotid artery (CCA) CIMT to Aβ in brain regions associated with Alzheimer’s disease (AD) and related dementias (ADRD), adjusting for age, sex, and other vascular risk factors.

Results:

Participants with higher mean ICA IMT had more Aβ in the precuneus (beta±standard error [β±SE]: 0.466±0.171 mm, p = 0.01) and the frontal, lateral, and retrosplenial regions (β±SE: 0.392±0.164 mm, p = 0.022) after adjusting for age, sex, vascular risk factors, and medication use. We did not find an association between any CCA IMT measures and Aβ or progression of ICA or CCA IMT and Aβ.

Conclusion:

Carotid atherosclerosis, as measured by ICA IMT, is associated with increased Aβ burden later in life. These findings support a link between vascular disease and AD/ADRD pathophysiology.
A model-based estimation and mapping of school-age children living in poverty in the local areas of South Africa
Authors: Laldaparsad Sharthi , Shiferaw Yegnanew A.
Published: July 2022

Poverty, inequality, and unemployment are on the rise in South Africa. The focus of this study is on school-age children in poverty. Education is a critical policy imperative for the country. Model-based small area estimation was conducted to estimate the different poverty measures for lower and upper bound poverty levels. The primary data sources are the Income and Expenditure Survey 2010/2011 and the 2011 national population census. The model diagnostics and the validation of the estimates showed that the model-based estimates at the local municipality level are more reliable than the direct estimates. There are significant variations in poverty across the local municipalities of South Africa; therefore, spatially targeted poverty alleviation programmes are more beneficial.
Forecasting Uncertainty Intervals for Return Period of Extreme Daily Electricity Consumption
Authors: Makatjane Katleho
Published: July 2022

The use of extreme value theory (EVT) is usually aimed at quantifying the asymptotic behaviour of extreme quantiles. The generalised Pareto distribution (GPD) with peaks-over-threshold (POT) approach is applied to bootstrap uncertainty intervals for the return periods of extreme daily electricity consumption in South Africa. The leeway of extremes on daily electricity consumption studied here is the impetus behind this study. To examine the effect of a time-based and extreme non-stationary trend in a dataset, a non-stationary GPD is cast-off in computing the shape parameter and, this resulted in the establishment of a type III GPD known as a Weibull class for the South African electricity sector. Results of this study revealed a non-stationary trend with a prediction power of 89.6% for the winter season and 85.65% non-winter season. This means that EVT provides a robust basis for statistical modelling of extreme values. Furthermore, a base for future researchers for conducting studies on emerging markets, more specifically in the South African context has also been contributed.

Published: July 2022

Transforming towards renewable energy consumption has become the main agenda for the country due to the drawback of consuming conventional resources. Climate change, energy security, and price fluctuation are the main factors contributing towards the penetration of renewable energy. Solar energy seems to be the most attractive due to unlimited source of energy, and fundamentally, its availability will never run out. This form of energy can also be used as an alternative in producing electricity. Malaysia has potential in developing solar energy for daily usage due to its location in the equatorial area and acquiring approximately 400–600 MJ/ m–2 of solar radiation every month. Universiti Utara Malaysia (UUM) is a public higher learning institution located in Sintok, Kedah. Sintok is a potential area for the installation of this solar system because the area has a longer peak sun hour rate than other areas. The aims of this study are: (1) to analyse the factors involved in solar installation, and (2) to examine the economic feasibility of solar installation at a university campus. This study used a qualitative approach, whereby the data were taken from interviews with the Development and Maintenance Department of UUM and Detrolic Solar Company. The solar implementation in UUM could reduce the cost of energy usage annually. Furthermore, UUM could gain revenue from the Net Energy Metering (NEM) 3.0 Government Ministries and Entities (GoMEn) incentive. Solar installation in the campus could hasten the effort of UUM moving towards a green and eco-friendly university campus. It is best believed that this effort could be a success if UUM is ready to move towards sustainable energy with solar consumption.

Published: July 2022

In emerging economies, examining the linkage between different markets has become crucial. We have examined the linkage between crude oil and Indian oil exploration companies' equity prices. The augmented Dickey-Fuller method is used to test the stationarity of the series. The Granger causality test, Vector autoregression (VAR), and correlation methodologies are used to examine the causality between the markets. The p-values of Granger causality tests are less than 0.05, which confirms that the crude oil price causes the price movements of Indian oil exploration equities. The VAR (2) model confirmed that the prices of HOCE, OIL, and ONGC follow the first and second lag, Reliance and PETRONET equities follow the first lag of International crude price. The impulse response function shows a positive response of Indian oil exploration equity returns for the positive shocks of crude oil return. The findings of this study may help the traders and investors in the equity market, energy equity investors.

Published: July 2022

Bibliometrics has proven to be an efficient method for quantitative research on the statistical behavior of academic production, which allows analyzing existing data and documents to resolve trends in specific research fields. Considering the database downloaded from Web of Science, with the help of Hitscite and VOSviewer data analysis tool and Microsoft Excel table, 7,259 publications related to solar energy research from 2010 to 2020 were obtained. The purpose of this research work is to apply bibliometric analysis methods to the development of scientific research on solar energy, as an important part of renewable energies, to evaluate its progress in the last decades and to describe these trends. The results showed that since 2015, research on solar energy has increased, especially in countries such as the United States and China, due to the Paris treaties where the goal is that the average temperature of the earth by the year 2100 does not exceed 1.5 °C. Since greenhouse gases are the cause of the greatest impact of the increase in global temperature, it is expected that researchers will focus on harnessing green energy and take a step further to reduce fossil fuels.

Published: July 2022

Access to energy is related to the essential aspects of modern survival, impacting production processes, access to knowledge and economic development. The global energy demand grows every year, and remote areas without connection to central grids need viable and sustainable alternatives for generating, distributing and storing energy at the local level. This paper presents an analysis through academic research, patent publications, reports and government information to map global trends and identify the opportunities for hybrid systems for power generation in microgrids from renewable sources and with several modes of generation. The data showed recent exponentially rising technologies with a tendency to continue for the next few years. China leads in isolation followed by USA and India. Countries like Brazil and Mexico, despite favourable conditions, do not present local technological development nor are they seen as a market of interest. Technological and research routes point to improving storage processes. Photovoltaic energy source was most used and to lesser extent wind, biomass, bioethanol, biogas, biodiesel and biohydrogen. Most of the inventions were focused on creating and improving machines, equipment, and systems to operate and control, utilizing the Homer software, for example.
Dynamic Relationship between the Return of Gold, Crude Oil, and the Stock Exchange of Thailand Based on a Vector Autoregressive Model
Authors: Uthumrat Wongtawan
Published: July 2022

This research aims to investigate the dynamic relationship between the return of gold (RGOLD), crude oil (RCO), and the stock exchange of Thailand (RSET) using the Vector Autoregressive model: VAR(p) to analyze the secondary monthly data from January 2002 to October 2022. The paper reports three key findings. Firstly, the Granger causality test reveals two direct relationships: one between RCO and RSET, and the other between RSET, RCO, and RGOLD. Moreover, the researcher estimated the relationship between these variables by using the VAR(1) model. Secondly, the impulse response function (IRF) is applied by Granger causality results. When a variable is shocked by an impulse in the system, the RCO to RSET response increases by 0.21 percent, the RSET to RGOLD response increases by 0.10 percent, and the RCO to RGOLD response increases by 0.04 percent, before decreasing and approaching equilibrium. Finally, variance decomposition shows that the greatest portion of total variation in RGOLD, RCO, and RSET can be explained by itself in the long run. Moreover, the variation of RSET can be affected by the variation of RCO while the variation of RGOLD can be affected by the variation of RCO and RSET. Thus, investors, securities analysts, or fund managers can use the study’s results for strategic investment planning.
Fuzzy Measures of Monetary and Non-monetary Deprivations in Tunisia
Authors: Ben Hassine Oula , Bouras Hela
Published: July 2022

The objective of this paper is to provide a measure of deprivation in Tunisia. The focus will be on non-monetary deprivation which will complement the profile of the poor in the country. The work is carried out on Tunisian data from the national survey on the budget, consumption, and the household’s standard of living (2015). The study tries to explore, in addition to the monetary dimension, the deprivations in Tunisia in the essential dimensions of a dignified and respectable human life: housing, education and health. The results obtained show a great disparity in monetary and non-monetary deprivation, particularly in the housing and education dimensions. Household characteristics seem to be an important element in the extent of deprivation. These include the location, region of residence as well as the socio-economic characteristics of the household head. The present paper stands out from several recent works on the phenomenon in Tunisia, based mainly on monetary indicators. By this aspect, this study contributes to a better understanding of poverty in the country.
Оn the issue of registration of human remains in mass graves of a sanitary nature at the stage of field work

Materials and methods. Based on the analysis of the descriptions of collective burials of the victims of the Mongol invasion in archaeological reports, taking into account the experience of foreign researchers of mass burials of the 20th century, an original method of fixing human remains of various completeness is proposed. Approbation of the methodology is described on the example of a study (2008, 2020) of a col-lective burial in 1238 in the archaeological object "construction No. 60" on the territory of the Yaroslavl Kremlin. Results. To resolve the issue of the method of registration of remains of different completeness, we turned to the archaeological practice of separating individual and mass material. As well as for individual archaeo-logical finds, it is proposed to introduce a field logbook of “individual anthropological finds”, in which they will be numbered and described with an indication of their completeness (“type” of deposition), localization and in situ position. The use of continuous numbering implies the general name of the numbered object, which, in our opinion, can be a name similar to that adopted for an individual material in archeology – “indi-vidual anthropological find”. Conclusion. The application of the proposed method will make it possible to more accurately describe the position and completeness of anthropological materials in mass graves of a sanitary nature or collective burials destroyed due to anthropogenic or other factors and containing redeposited remains. A careful de-scription and maximum "personification" with this approach will contribute to the realization of a paleoan-thropological material as a source for bioarchaeological and historical reconstructions. This corresponds to the modern contextual approach in archeology, aimed at a comprehensive study of the communities of the past based on a detailed analysis of all types of sources discovered during excavations.
The Beja of Atbay: the results of the first years of ethnographic studies during archaeological and anthropological expedition in Nubian desert

Introduction. The Atbay region, which we refer to in this article, has been the periphery of large state formations since the time of the Egyptian civilization. The question of the genetic continuity of the ancient population of Atbay and the modern ethnic groups living in this territory – the Beja, still causes debate in the scientific community. In the article we propose to turn to the cultural continuity of the population of the re-gion, mediated by unique geographical and political factors, which, in the case of Atbay, have remained virtually unchanged for centuries. Materials and methods. Different works on history and social anthropology relating to the Atbay re-gion and the ethnic group considered in the article (the Beja) became the main sources for the article. The information available in the research literature is compared with the data that we managed to collect during the first experience of field research among the Beja Bisharin as part of the Nubian archaeological and an-thropological expedition of Moscow State University. Results and discussion. The article provides an overview of the main works and scientific concepts related to Bedja of the Atbay region. In historical monographs, focused mainly on the most ancient and me-dieval periods, the Bedja are perceived as the Proto-Egyptians or the descendants of the Medajs of the era of the Middle Kingdom. During ethnographic research undertaken as part of the archaeological and anthro-pological expedition of Moscow State University, it was found that the Atbay region is very different from the regions of the Nile Valley and the Red Sea coast. Based on the studies of 2018-2019 seasons the idea was put forward that the special landscape and climate of the region prevent its incorporation into the exist-ing state formations (Ancient Egypt, Arab Caliphate), and reinforce a local peripheral culture that exists and reproduces itself for several millennia while remaining distinct (in part opposed to) the dominant historical culture. Conclusion. As a result of studying various written sources and comparing them to the field materials, we developed a hypothesis of cultural continuity of the population of the Beja in the region, mediated pri-marily by its special climatic and historical conditions. This hypothesis, in our opinion, provides a promising theoretical framework for further research on the cultural characteristics of Beja Bisharin of Atbay. The first field experience also confirmed the idea of the closeness of Beja communities given in literature. We intend to use these findings to develop strategies for further research.
Inclusión y atención a la diversidad en el aula rural multigrado: Un estudio de caso
Authors: De los Santos-Gelvasio Andrea
Published: July 2022

Las aulas rurales multigrado se caracteri­zan por ser un amplio ejemplo de diversidad dentro de la diversidad. En ellas converge un alumnado de diferentes edades, grados, intereses, necesidades y capacidades, y se crea un ambiente propicio para el desarrollo de prácticas pedagógicas inclusivas, diversas y heterogéneas. A pesar de esto, es común ver que en estas aulas intervienen múltiples factores que limitan al profesorado en el desarrollo de una enseñanza contextualizada y adaptada a las necesidades del alumnado. Por tanto, esta investigación pretende analizar cómo el profesorado de aula rural multigrado aborda la inclusión y la atención a la diversidad en su práctica pedagógica. Para la consecución de este objetivo, esta investigación se desarrolla como un estudio de caso etnográfico, partiendo de un aula rural multigrado de la República Dominicana y recabando información mediante revisión documental, entrevistas en profundidad y observaciones de aula. Los resultados indican que la falta de formación contextualizada y de un seguimiento adecuado imposibilitan que en estas aulas se desarrollen estrategias y actividades diversas, complejas y articuladas con el entorno, que profundicen en el conocimiento a la vez que se atiende la inclusión y la diversidad, esto necesariamente conduce a repensar y reformular las políticas educativas y los programas de formación docente inicial y continúa relacionados con este aspecto.

Authors: Flores-González Norma
Published: July 2022

Debido a un estado pandémico derivado de la covid-19, la educación en México transitó hacia modelos y entornos educativos virtuales; esto requirió de los docentes el desarrollo de nuevas competencias profesionales con el fin de responder a las características propias de esos contextos. Ante esta situación, resulta imprescindible indagar sobre la adaptabilidad docente a entornos virtuales de aprendizaje. El objetivo de la presente investigación es describir la adaptabilidad de los docentes a los entornos virtuales a través de la caracterización de las dimensiones de su perfil docente. La metodología empleada es cuantitativa con alcance descriptivo y corte transversal. La muestra está constituida por 268 evaluaciones docentes realizadas por los estudiantes de los dos programas de licenciatura (inglés y francés) de la Facultad de Lenguas durante los periodos primavera-otoño de 2020 y primavera de 2021. Los resultados obtenidos muestran una adaptabilidad progresiva a la modalidad virtual y los principales hallazgos radican en la identificación de tres dimensiones: académico-pedagógica, técnica y socioafectiva, que subyacen a su perfil docente y hacen plausible su praxis en un entorno nuevo mediado por tecnología. No obstante, se distinguen áreas de oportunidad tales como la aplicación de la dimensión técnica, la necesidad de formación docente en el uso de las tecnologías del aprendizaje y conocimiento (TAC) y diseños tecno-pedagógicos. En conclusión, las aportaciones del estudio derivan en contribuciones de tipo metodológico para describir el actuar docente ante la modalidad imperante y de tipo teórico para la toma de decisiones en pro de mejores prácticas docentes.
Simulation of Tomographic Acquisition and Reconstruction Slice for Industrial Machine Rotor with Fixed-Angle Scanner
Authors: Ahmedbacha M R , Benouar A , Khorsi A , Akermi N , Kaddouri K
Published: July 2022

Rotating machines such as electric motors and pumps are the heart of any industrial production chain. Rotors are usually the most worn parts, and the preventive maintenance of these vital organs, although necessary, remains penalizing for the production line because the machines are stopped and disassembled for a lengthy period during the inspection phase. This paper suggests a simulation of optimized tomographic reconstruction by cone beam acquisition geometry to scan a functioning machine rotor with high X-ray energy. In this work we propose a simple design of a fixed-angle projection scanner. Rotating projections are replaced by synchro-rotation to the nominal angular velocity of the rotor. The simulation results demonstrate that it is possible to adapt the filtered back-projection algorithm to compute a tomographic image of the rotor by a single projection device.

30 év telt el azóta, hogy a Varsói Szerződés, amelynek hazánk is tagja volt, felbomlott, és több mint 20 év telt el  azóta, hogy egy másik katonai szövetséghez, a NATO-hoz csatlakoztunk. Ez idáig azonban jelentős modernizáció nem  valósult meg a Magyar Honvédségben. A honvédség földi telepítésű légvédelmi eszközeinek a jelentős része még a rendszerváltás előtti időkben állt hadrendbe.

Authors: Amaral Patrick Colissi do , Machado Caroline Duarte , Reichert Taíse Gabriele
Published: July 2022

No final do ano de 2019, um vírus até então desconhecido se espalhou rapidamente pelos países da Ásia e da Europa, sendo esse surto reconhecido como uma pandemia em março de 2020. Denominado como SARS-CoV-2, esse vírus pertence à família Coronaviridae e é popularmente conhecido como “coronavírus” ou “COVID-19”. Diante disso, a pandemia do coronavírus abalou a saúde pública e a economia mundial trazendo grandes impactos para a população. Inicialmente, idosos foram declarados como o principal grupo de risco, entretanto, destaca-se que um outro grupo também merece atenção: as gestantes. No período gestacional, a mulher vivencia inúmeras alterações emocionais e físicas, exigindo uma demanda maior de cuidados à saúde. Trata-se de mudanças normais da gravidez, mas que diante de uma pandemia podem ser potencializadas, produzindo efeitos adversos. Dentro desse contexto, a questão norteadora para esse estudo foi definida como: quais impactos uma pandemia como a da COVID-19 pode causar na saúde e na assistência às gestantes? Este artigo tem como objetivo geral analisar os impactos que a pandemia da COVID-19 tem causado na saúde e na assistência prestada às gestantes. O método utilizado consiste em uma revisão integrativa, onde 14 artigos que abordam sobre o tema proposto foram criteriosamente selecionados e analisados. Os principais resultados notados através deste estudo foram quanto ao nível mental e assistencial. Sendo assim, observou-se um impacto significativo nos níveis de ansiedade, estresse e depressão em gestantes de diversos países, assim como aumento nos cancelamentos de consultas de pré-natal, além de relatos de medo, preocupação e dúvidas em razão do avanço da pandemia. Todavia, não foram encontradas muitas informações a respeito da taxa de letalidade do vírus nas gestantes ou dos riscos de transmissão vertical da mãe para o filho(a). Portanto, concluiu-se que a pandemia do Coronavírus trouxe impactos significativos na saúde mental das gestantes e as afastou das consultas de pré-natal por medo de contaminação, por falta de informações e pela dificuldade de acessar os serviços de saúde mediante as medidas restritivas e a crise financeira.
Genetic protocols for DNA extraction from white-tailed deer cast antlers to confirm individuality
Authors: Carter Zach , Peterson Brian , Schoenebeck Casey , Carlson Kimberly
Published: July 2022

White-tailed deer (Odocoileus virginianus) are the most sought-after deer species in America. The antlers of mammals, such as deer, are one of the fastest regenerative tissues in the world and are grown and naturally cast every year. Research on cast antlers have been used for a variety of purposes including population comparisons and impacts of deer health due to climatic stressors. When investigating cast antlers, it is important to confirm individuality of match sets in addition to antlers of the same individual between years. Therefore, individuality must be confirmed genetically, and protocols must be developed and established to do so. Our objectives were to 1) establish a genetic protocol to harvest DNA from cast antlers using connective tissue, and 2) determine individuality from subsequent years and match sets. When fresh antlers are cast, they leave behind a viable connective tissue from which DNA can be extracted. The DNA was successfully extracted from the skin rings harvested from naturally cast antlers. This study developed viable methods to confirm individuality, which aid researchers and wildlife biologists in a better understanding of the white-tailed deer herd as they set management goals and harvest regulations.
Reading Contemporary French Literature
Authors: Motte Warren
Published: July 2022

This book focuses upon a dozen French writers who have helped to set the terms for contemporary French literature and its horizon of possibility. Though they have pursued significantly different paths, each one of them is committed to the principle of literary innovation, to making French literature new. They work in full cognizance of literary history and of the tradition that they inherit, even as they reshape that tradition in each of their books. They invite their readers to take a critical stance with regard to those books, and to participate actively in the construction of literary meaning. Both bold and mobile in their own practice, they encourage us to be just as agile in our own readerly practice, offering us a rare degree of franchise in a literary dynamic founded on the notion of articulation.

Writers discussed include Raymond Queneau, Edmond Jabès, Georges Perec, Marcel Bénabou, Jacques Jouet, Marie NDiaye, Marie Cosnay, Bernard Noël, Jean Rolin, Jacques Serena, Julia Deck, and Christine Montalbetti.
Improving Multilingual Frame Identification by Estimating Frame Transferability
Authors: Sikos Jennifer , Roth Michael , Padó Sebastian
Published: July 2022

A recent research direction in computational linguistics involves efforts to make the field, which used to focus primarily on English, more multilingual and inclusive. However, resource creation often remains a bottleneck for many languages, in particular at the semantic level. In this article, we consider the case of frame-semantic annotation. We investigate how to perform frame selection for annotation in a target language by taking advantage of existing annotations in different, supplementary languages, with the goal of reducing the required annotation effort in the target language. We measure success by training and testing frame identification models for the target language. We base our selection methods on measuring frame transferability in the supplementary language, where we estimate which frames will transfer poorly, and therefore should receive more annotation, in the target language. We apply our approach to English, German, and French – three languages which have annotations that are similar in size as well as frames with overlapping lexicographic definitions. We find that transferability is indeed a useful indicator and supports a setup where a limited amount of target language data is sufficient to train frame identification systems.
Desain, Simulasi dan Analisis Peningkatan Range Resolution Sistem Radar FMCW
Authors: Ansori Mohamad
Published: July 2022

Range resolution as one of the parameters of the radar system becomes very important and need to be upgraded to provide accurate target distance information. Increased bandwidth can be done however is limited to devices for Direct Digital Synthesizer (DDS) that are used and will enlarge the noise and power consumption of system Frequency Modulated Continuous Wave (FMCW) radar. To improve range resolution, output signal and bandwidth linieritas chirp both plays is very important and the sampling rate of the engineering efforts for improved range resolution still experience barriers when based on peak detection. So to improve range resolution alternatives that can do that is maintain linieritas or increase bandwidth and not just based on peak detection. In this paper are discussed improved range resolution without increasing bandwidth using curve fitting method by way of comparing the output signal of the mixer and beat frequency shift signal mixer output to both match (match). Error of measurement range resolution is affected by the phase errors due to the lack of frequency of linieran beat, so that needs to be done shifted frequency curve fitting method using beat against the sweep of raw data (output ADC) to earn optimum beat frequency (optimum resolution range). Range resolution for Radar Demonstration Kit (RDK) using curve fittng methods obtained results an increase of 30% and the shifting of the beat frequency of 3KHz.

There are three levels in producing oil or natural gas: primary recovery where oil flows into the wellbore by itself; secondary recovery where oil flows with the help of water or gas injection; and tertiary recovery, commonly called Enhance Oil Recovery (EOR). Total recovery from one oil field is about 50% -60% of OOIP. With primary and secondary recovery 30% -40% can be obtained from OOIP, it is expected that the remaining 20% -30% can be taken with EOR. This study investigated EOR by injection of various surfactant concentrations at temperatures of 30°C and 80°C using brine with salinity of 10,000 ppm by imbibition. The aim of this research is to know the effect of surfactant concentration and salinity of the formation water on oil acquisition in relation to sandstone permeability, and to find out what level of concentration to the average permeability rate with temperature close to reservoir average temperature (80°C), can be obtained a minimal Sor so that RF (Recovery Factor) to be maximal. The methodology used is to measure: the physical properties of rocks and fluids (the solution used), the interface voltage and selected the best solution (the smallest interface voltage), and soaking the rock with Amot test glass. From this study, it can be concluded that the addition of concentration will decrease the density, but the addition of temperature will decrease the density and viscosity; the addition of the surfactant and temperature concentration will decrease the interface voltage until the CMC point is reached; good permeability and porosity may not produce good results when clay contamination is present

Published: July 2022

The die design process for casting requires repeated testing in order to get a good die and produce a product that is as planned, which takes a long time and costs a lot for die making in this trial. The purpose of this study is to determine a more efficient process in die design by conducting a casting analysis using a MagmaSoft simulation. The sample part used in this study is a motorcycle brake master cylinder which will be made by the Gravity Casting process with aluminum material. The basic method used is die design using CAD by calculating Shrinkage allowance, and casting simulation using MagmaSoft software to find out various possible defects during the casting process, such as filling, air trap, solidification, hot spots, and shrinkage porosity. The simulation results show that in the filling process there is no indication of cold shot and no air trap problem, solidification and hot spots are good and occur in the part area, and there is little porosity. In general, the simulation results show that the die design has met the requirements, although there is porosity, this porosity occurs in the area that will be lost after the machining process
