Authors: Camarinha Pedro I.M. , Simões Silvio J.C. , Bernardes George P. , Trannin Isabel C.B.
Published: June 2022

This manuscript aims proposing a methodology for correlating soil porosity to the respective geological units using geostatistical analysis techniques, including interpolation data by kriging. The site studied was in Lorena municipality, Paraíba do Sul Valley, southeastern Brazil. Specifically all studies were carried out within an area of 12 km2 located at Santa Edwirges farm. The database comprehended 41 soil samples taken at different geological and geomorphologic units at three different depths: surface, 50 cm and 100 cm depth. The geostatistical analyses results were correlated to a geological mapping specifically elaborated for the site. This mapping accounts for two different geological formations and a geological contact characterized by a shearing zone. The results indicate the existence of a significant relationship between the soil porosity and the respective geological units. The studies revealed that the residual soils from weathered granitic rocks tend to have higher porosities than the residual soils from weathered biotite gneiss rocks, while the soil porosity within the shearing zone is relatively un-sensitive to the respective geological formation. The spatial patterns observed were efficient to evaluate the relationship between the soil porosity, geology unit and the and geomorphology showing a good potential for correlating with others soil properties such as hydraulic conductivity, soil water retention curves and erosion potentials.

Numerous socio-economic benefits are associated with the oil industry. However, problems cannot be neglected, resulting in many accidents that can occur at any production stage of this industry. A serious problem created by this industry is environmental contamination by hydrocarbons. Gasoline in contact with infiltration water, the aromatic constituents, in particular the BTEX group, partially dissolve being the first contaminants to reach the groundwater. Studies published in the literature indicate that biological degradation is the main mechanism responsible for reducing the concentration of these toxic pollutants. Laboratory studies of this kind have been conducted in small scale columns, where the biological field conditions are not well reproduced. However, studies conducted in a larger scale with structured soil, remaining closer to field conditions, evidenced biodegradation processes of BTEX. This paper presents the in situ construction, instrumentation and monitoring of a large rectangular block of undisturbed residual gneissic soil, subjected to a horizontal flow of a contaminant solution composed of water, benzene and toluene to evaluate the biodegradation of these compounds in different points of the block over time. During the period of 85 days, samples of the percolating solution were periodically collected from pre-established monitoring points and the concentrations of benzene and toluene were determined using a coupled technique of gas chromatography and mass spectrometry (GC-MS). Based on the monitoring results, decay in the concentrations of the compounds over time and along the length of the block was observed. These results indicated, consistently with the biological characterization of the soil that showed the existence of microbial degrading activity, the occurrence of biodegradation of benzene and toluene, and, by an extraction process, the retention of these compounds in soil was also verified.

Published: June 2022

This paper presents the development of an instrumented channel for two-dimensional multiphase flow of automotive fuels in unsaturated soils. Flow experiments were performed using water or diesel in an eolian sand at residual water saturation, a particular case of multiphase flow. Aspects such as the visual monitoring of the infiltration experiments and the great reproducibility of the developed experimental protocol can be cited as highlights of this research. The two sets of tensiometers, hydrophilic and hydrophobic, used during the diesel experiment, responded differently. While the hydrophobic tensiometer, filled with diesel, measured the full range of diesel suctions, the hydrophilic tensiometers, filled with water, responded less effectively to the passage of the diesel wetting front. Flow experiments were modeled using Philip’s equation, considering the flow in unsaturated conditions above the wetting front. The time required for the diesel wetting front to reach the tensiometers was about 8.8 times higher than for water, considering the tensiometer readings, and, about 6.1 times higher than for water considering the visual observations. These values are comparable to the ratio of fluid mobilities [(w/w)/(diesel/diesel) = 5.5] of water and diesel.

Authors: Collares Eduardo G. , Júnior Ivan F. , Motta Leila A.C.
Published: June 2022

The quartzite found in rock formations in the Southwestern Minas Gerais - Brazil has been, along the years, explored and commercialized as “coating stone”. The quantity of waste coming from the processing and exploration process, however, is superior to 90% from the extracted product in most of the mining sites, determining a serious environmental passive. This work presents results which can motivate the alternative use of the materials that are dumped on piles of waste. The research involved a petrographic analysis of quartzite occurring in the principal mines of the region; evaluation of aggregates produced in two kinds of crushers; evaluation of the physical and mechanical properties of the rock and evaluation of the physical and mechanical properties of the concrete manufactured with the quartzite aggregate. The results of the technological tests carried out on the rock material were satisfactory and meet all the specifications for the use in concrete. The samples of concrete prepared with the quartzite aggregate presented results of strength similar to the ones manufactured with the aggregate which are used commercially in the region today.
Characterization, Hydraulic Conductivity and Compatibility of Mixtures of Tropical Soil and Bentonite for Barrier Usage Purpose
Authors: Morandini Thiago L.C. , Leite Adilson L.
Published: June 2022

Compacted tropical soils have great potential to be used in barriers, once some technical issues are correctly addressed, including low hydraulic conductivity and compatibility to the disposed fluids. This paper involves a laboratorial study of the hydraulic conductivity of mixtures of a tropical soil sample and bentonite and also their compatibility to different chemical solutions. The experimental program consisted of (1) sample characterization, (2) hydraulic conductivity determination using a triaxial cell, and (3) compatibility assessment with different chemical solutions (HNO3 , NaOH, NaCl, and ethanol) using the modified Atterberg Limits. The characterization results revealed important changes in the index properties of the tropical soil sample as the result of the bentonite addition, especially in the plasticity, cation exchange capacity and free swelling. The hydraulic conductivity, in turn, experimented significant decreasing as the proportions of bentonite and confining pressure increased. The compatibility results showed a significant reduction in the plasticity of the samples when subjected to the chemical solutions, especially for the salt solution. In general terms, the addition of bentonite reduced the compatibility of the samples.
Cyclic T-Bar Tests to Evaluate the Remoulded Undrained Shear Strength of the Sarapuí II Soft Clay
Authors: Jannuzzi Graziella M.F. , Danziger Fernando A.B. , Martins Ian S.M.
Published: June 2022

The undrained remoulded shear strength of a clay, sur, is an important parameter in the design of a number of geotechnical applications. In the case of onshore tests the value ofsur is generally obtained from vane tests. Recently, cyclic T-bar tests have been used to obtain the sur value, especially for offshore applications. Seventeen T-bar cyclic tests in two deployments have been performed at Sarapuí II soft clay test site. In a third deployment only penetration was recorded. The presence of roots has influenced the values of the initial penetration in one of the deployments, as observed in another test site, which is a consequence of the shape of the penetrometer and may be considered a shortcoming of the test. Therefore, to know whether roots have influenced the test results in a site at least two repeatable tests must be performed. If cyclic tests are performed, their results can provide a good indication of the influence of the roots. Considering the vane shear test as reference for obtaining su and sur, NT-bar obtained from tests not affected by the roots ranged from 8.8 to 10.9, with an average of 9.8, while Nrem, T-bar ranged from 14.1 to 19.5, with an average of 16.3. Therefore NT-bar values (related to the natural condition) were smaller than Nrem, T-bar (related to the remoulded condition). The equations suggested by Yafrate et al. (2009) to evaluate the remoulded penetration resistance, the whole degradation curve and the sensitivity, based only on the initial penetration and extraction resistances have provided good results for the Sarapuí II soft clay, except in the case of very shallow depths.
A Short Review on the Importance of Colonnades, Entablatures and “Fault Joints” for the Excavation of Basaltic Rocks
Authors: Sadowski Georg R.
Published: June 2022

Entablatures, colonnades and “fault-joints” have been found in many excavations of dam foundations, tunnels and quarries in basaltic rocks of southern Brazil, but frequently they were not formally identified as such, and the two first, only rarely. This lack of recognition led many times to misunderstanding of their importance to slope stability and foundation problems. This short note reviews their basic definitions and stresses the influence of their properly consideration in the development of geotechnical projects.
The Influence of Moisture Content on Tensile and Compressive Strength of Artificially Cemented Sand

Published: June 2022

Applying Portland cement to soils is an excellent technique when it is necessary to improve local soil for the construction of stabilized pavement bases and to have a support layer for shallow foundations. Consoli et al. (2007, 2009, 2010) developed a rational dosage methodology for artificially cemented soils based on porosity/cement index, which can be applied to unconfined compressive strength, as well as to splitting tensile strength. Furthermore, a unique qt /qu relationship was found, independent of the cement content and voids ratio. Following the assessment of the main factors that influence the strength of artificially cemented soils, the present research aims to quantify the influence of the moisture content in the tensile and compressive strength of an artificially cemented sand. A program of splitting tensile tests and unconfined compression tests was carried out. There were tested three voids ratio (0.65, 0.73 and 0.81), four cement contents (3%, 5%, 7% and 9%) and five moisture contents (6%, 8%, 10%, 12% and 14%). The results show that the reduction in moisture content of the compacted mixture increases both the tensile and compressive strengths. Furthermore, it has been shown that qt /qu relationship was kept constant, being independent of the porosity/cement ratio and the moisture content.
Joint examination of climate time series based on a statistical definition of multidimensional extreme
Authors: Szentimrey Tamás , Izsák Beatrix
Published: June 2022

The joint examination of the climate time series may be efficient methodology for the characterization of extreme weather and climate events. In general, the main difficulties are connected with the different probability distribution of the variables and the handling of the stochastic connection between them. The first problem can be solved by the standardization procedures, i.e., to transform the variables into standard normal ones. For example, there are the Standardized Precipitation Index (SPI) series for the precipitation sums assuming gamma distribution, or the standardization of temperature series assuming normal distribution. In case of more variables, the problem of stochastic connection can be solved on the basis of the vector norm of the transformed variables defined by their covariance matrix. We will present the developed mathematical methodology and some examples for its meteorological applications.
On the correction of multiple minute sampling rainfall data of tipping bucket rainfall recorders (Short Contribution)
Authors: Rácz Tibor
Published: June 2022

In the last decades of the 1900s, the tipping bucket rainfall gauges (TBG) were used to record the sub-daily rainfall data. In the first period of the rainfall data recording, as a result of the lack of efficient data storage and data transmission, the sampling period of the TBG devices was chosen in a magnitude of 10–20 minutes. Consequently, there are historical datasets characterized by several minutes long sampling periods. Since the turn of the 2000s, the data handling has been revolutionized; the sampling period has diminished to one minute. There is a systematic error of the TBG technique which has been investigated since the middle of the 1900s. Between 2004 and 2008, a comprehensive research was performed to determine the correction equation for several TBG devices. These results can be utilized for the short sampling period measurements (one minute sampling), but for longer sampling period data, further corrections are needed. In this paper, a supplementary correction is presented. On the base of the mathematical determination of the correction factor, simple estimation will be proposed to be able to execute the necessary correction. After the presentation of the correction factor, a general correction factor is proposed for larger geographical regions and wide time span of the measurements. The revision of the historical rainfall data recorded by TBG devices can be important in several issues, such as the re-evaluation of intensity-duration-frequency (IDF) curves, and in other fields.

Published: June 2022

One of the main success drivers of the Fourth Industrial Revolution is the integration of information technology and industry, which encourages innovation through collaboration between industry and academia. As a result, fostering innovative behaviour among undergraduates is essential for success in higher education throughout this revolution. The purpose of this study is to examine the direct effects of capability (leadership, technological literacy, interaction, knowledge sharing, and collaboration) on innovative behaviour and the indirect effect of knowledge integration's mediating role. Data from 3,230 undergraduates was collected and analysed. The provided hypotheses were validated using structural equation modelling, which demonstrated that capability significantly influenced the success of adopting innovative behaviour. Furthermore, we observed that knowledge sharing was the most powerful predictor. We also discovered that the intervening knowledge integration had an indirect effect, indicating the presence of a relationship between capability and innovative behaviour through this variable. When the direct and indirect effects were evaluated, the direct effect was substantially stronger than the indirect effect. The study's practical implications should focus strongly on promoting innovative behaviour and knowledge integration in the process of establishing appropriate educational programmes for universities. Furthermore, universities should develop strategies to encourage undergraduate students to share their knowledge and abilities with others since this improves performance and increases awareness of new prospects for innovation. In future research, we should include more educational institutions in our study, such as high schools, technical schools, and graduate students. Doi: 10.28991/ESJ-2022-SIED-07 Full Text: PDF

El artículo realiza una lectura teórica cruzada entre los estudios de discapacidad y perspectivas foucaultianas, con el fin de analizar la profanación de los dispositivos modernos de biopoder y medicalización que situaron la discapacidad como una desviación indeseable de la existencia normativa. Su objetivación desde movimientos y estudios sociales posibilitó la emergencia en el Norte Global de un dispositivo que desplazó su circunscripción del ámbito médico pero que se caracterizó por su producción en espacios atravesados por patrones de desarrollo capitalista y colonial, que condicionan todavía epistémica y políticamente las aproximaciones a ella en otras locaciones del globo. En esta línea, el artículo da cuenta de las reconfiguraciones de los dispositivos, junto a las resistencias descoloniales desde el Sur Global.
La nueva eugenesia del individualismo neoliberal. Una discusión desde el modelo social de discapacidad
Authors: Anchondo Pavón Sandra , Gallardo Macip Cecilia
Published: June 2022

Los prejuicios en torno a la discapacidad se encuentran tan arraigados en las sociedades contemporáneas, especialmente, en el contexto latinoamericano, que es necesario reflexionar acerca de las raíces de dicho fenómeno. Así, ahondar en los proyectos eugenésicos del siglo pasado, en relación con las nuevas formas de eugenesia contemporáneas, permite comprender lo que una concepción capacitista y funcional ha provocado en la noción que poseemos actualmente de la naturaleza humana. Más aún, cuando detrás de dichos proyectos hay una defensa instrumental e individualista que deja de lado el carácter relacional y social de los seres humanos. El presente artículo insiste en la necesidad de volver a mirar el modelo social de discapacidad para comprender que ésta se produce en el encuentro de las limitaciones personales.

Published: June 2022

This research studies the shaft strength of a BLDC electric motor. A Shaft is one of the components in a rotary engine and functions to transmit power. The design calculation is needed to determine the effect of the strength of the material being treated. The strength analysis of the shaft used FEM (Finite Element Method). The shaft is modeled on the manufacturing design and tested by numerical simulation with Ansys Mechanical 14.5-BRIN commercial license software. The static simulation used a structural statics module with static and dynamic load input. The research method comparing the results of FEM simulations with two different types of materials is determined. Based on the simulation parameters, the selected material types are JIS S45C tempered and AISI 1045 cold-drawn. The simulation results represent the maximum stress (von Mises) and total deformation. The deformation value of S45C tempered material is slightly higher than that of AISI 1045 cold drawn. However, both materials have the same maximum von Mises stress.

Una ontología negativa de la multitud. Soledad y política en Jorge Alemán y Ernesto Laclau
Authors: Speziale Tomás
Published: June 2022

Este artí­culo busca revisitar la crí­tica que Ernesto Laclau y Jorge Alemán han hecho en las últimas décadas a los pensadores contemporáneos de la multitud, a fin de sostener que la teorí­a del populismo no debe necesariamente descartar la figura teórico-polí­tica de la multitud. Se argumentará que la idea de una Soledad: Común propuesta por Alemán retoma la tradición laclausiana, habilitando simultáneamente una nueva conceptualización sobre la relación entre sujeto y multitud.  Este punto permitirá poner a dialogar psicoanálisis y deconstrucción, afirmando que entre ellos hay en común una ontologí­a negativa de la multitud, que los distancia de las perspectivas que ven en la multitud una potencia positiva inmanente de los cuerpos que tienden naturalmente a sublevarse. La pregunta que estructura este trabajo es, pues, si es posible sostener la potencialidad teórica y polí­tica de la multitud en el marco de una ontologí­a (polí­tica) negativa.
Trayectorias de la filosofí­a clásica alemana en la trama literaria del ateí­smo ruso.
Authors: Narváez Ángelo
Published: June 2022

Resumen: En este artí­culos abordaremos la interpretación secularizada de la filosofí­a hegeliana de la historia en los cí­rculos culturales y literarios rusos desde mediados del siglo XIX hasta comienzos del siglo XX como una clave de interpretación del conflicto sobre el ateí­smo en la Rusia prebolchevique. En esa trama, amplia y diversa, la experiencia estéticas de Dostoievski aparece como un momento especialmente representativo de un largo proceso de tensión entre transformación y conservación de lo que en ese periodo histórico se entendió como la "espiritualidad" rusa, por oposición a una hipotética laicización europea occidental. Con ello analizaremos también el debate sobre el ateí­smo en los cí­rculos literarios como antesala de la institucionalización del ateí­smo en los primeros años de la experiencia soviética del poder.
Neoliberalismo: ¿utopía de una sociedad de la empresa?
Authors: Pablo Martí­n Méndez
Published: June 2022

La utopí­a de una sociedad regulada por los mecanismos de mercado ha sido objeto de intensos e interminables debates. El eje de discusión gira en torno a sus condiciones de realización. ¿Puede el mercado funcionar como un mecanismo de regulación social sin fracasar en el intento? ¿Hay un proyecto de sociedad de mercado que no se revierta en un capitalismo defectuoso e indeseado? Aquí­ surge la cuestión del neoliberalismo, entendido generalmente como el intento de reactualizar la vieja utopí­a liberal de la sociedad de mercado. Este artí­culo señala que el neoliberalismo tiene una utopí­a singular, que difiere en varios aspectos de clásica la sociedad de mercado. Para ello se revisan las ideas y propuestas de algunos economistas identificados con el Ordoliberalismo alemán de las décadas de 1930 y 1940. Según nuestra hipótesis de lectura –tomada en parte de los análisis e interpretaciones de Michel Foucault–, el Ordoliberalismo abre paso al proyecto de una sociedad donde los individuos no actúan en forma aislada y atomizada, sino en el marco de las pequeñas y medianas empresas. Más que el proyecto de una sociedad de mercado, es la utopí­a de una "sociedad de la empresa".

Authors: Fuica-García Fernando
Published: June 2022

Este artículo busca develar la presencia o ausencia de los referentes interculturales en los documentos formales de los Comités de ética de la investigación (CEI) de universidades chilenas adscritas al Comité de Rectores. Se analizaron documentos públicos de veintinueve universidades. Los principales hallazgos dan cuenta de la ausencia de resguardos éticos asociados a las voces originarias y migrantes en estudio y los procedimientos realizados al enfrentar el estudio de fenómenos interculturales. Se concluye un perfil decolonial ausente en los CEI y una delicada proximidad a la justificación de su existencia como cumplimiento de los requisitos investigativos occidentales.

Hybrid vapor compression systems based on adsorption are recognized as a viable alternative to traditional energy-intensive compression systems. Solar-powered hybrid adsorption-compression refrigeration systems feature a solar-powered silica gel/water-based adsorption cooling system paired with a traditional compression system that utilizes R134a as a refrigerant. Herein, the system feasibility of a solar-operated hybrid adsorption-compression refrigeration system has been evaluated theoretically using typical climatic data of Alexandria, Egypt. Mathematical modeling is generated and compared to the most relevant experimental data. PVT collectors are exploited to drive both the adsorption and the compression units. Simulation results suggest that using a three-to-one system size ratio between the adsorption and compression subsystems might considerably raise the COP from 2.9 to 5 for the compression system. It is observed that at an ideal size ratio of 7, the proposed system can considerably deliver an energy saving of 30.8 percent, compared to the hybrid system of the size ratio of 3, which attains only energy savings of 22.1 percent. Furthermore, the utilization of PVT collectors might feed the hybrid system by 3.474 kWh and augment the electric grid by 100 kWh, at an ideal size ratio of 7. Overall, investigating hybrid adsorption-compression systems might offer unique insight on optimizing the performance of conventional counterparts.

Authors: KHAN Mohd Faısal , KHAN Mohd Rizwan
Published: June 2022

Self-excited induction generators (SEIGs) have been rigorously investigated in last few decades owing to their suitability for standalone renewable energy applications. Various issues pertaining to their modeling and control are quite aptly addressed in several analytical and experimental studies. However, these analyses are often focused on elaboration of proposed innovations and findings while the important details on modeling and implementation of SEIGs are left to be explored by readers. In this paper, a step by step approach for the mathematical modeling of three-phase self-voltage regulating, short shunt SEIG in stationary reference frame is explained. Subsequently, the developed d-q model of SEIG is implemented in terms of a simulation model. The developed model is then employed to carry out performance analysis of 3-phase, 2.2 kW SEIG supplying R-L load. All the results are verified with good accuracy in a SEIG test-rig whose details are included in the paper. The prime objective of this work is to provide a consolidated source for developing research resources of a self-voltage regulating three phase SEIG.

Published: June 2022

The existing value chains of the energy companies are eroding. Trends such as digitization, big data and AI have long since arrived in the energy industry. These demanding framework conditions are increasingly forcing energy companies to introduce new business models. A possible business model lies in smart home applications. This paper analyzes the added value of smart home applications for customer loyalty of energy companies and electricity customers, as well as to identify obstacles in the context of practical implementation. This paper examines smart home applications and the intelligent control and integration of photovoltaic systems. Above all, the avoiding of peak loads will play an important role in the energy grids of the future. The methodology describes the necessary framework conditions existing for the generation of digital innovations. Moreover, it examines the factors leading to increased customer loyalty through the value-added services and offers a load shifting potential to relieve the distribution networks. It is found that the value-added services can offer increased customer loyalty to the energy companies. Even though smart home-based services are highly relevant in a rapidly growing target market, there will only be a broad acceptance of them for the load control, if the user is offered an added value, for example by load-variable electricity tariffs. Energy companies wishing to position themselves as digital service providers must have smart home-based services such as intelligent load control and load-dependent tariff models, which enable users to add a financial value.
Performance assessment of a magnetohydrodynamic power generation system: Division of the exergy destruction rate into its sub-portions
Authors: HALOİ Prabin , GOGOİ Tapan
Published: June 2022

Sustainable and environmental friendly energy extraction and utilization is the foremost priority of the energy sector to meet the present and near future energy demands. The need of the day is to have efficient and eco-friendly energy conversion technologies either through the enhancement of the existing technologies or the development of some all-new technology. The present study investigates a standalone open-cycle Magnetohydrodynamic (MHD) power generation system using the advanced exergy analysis analytically. The effects of distributing the exergy destruction into endogenous/exogenous and avoidable/unavoidable on the improvement possibilities and the mutual interlinkages among the different units of the MHD system have been studied. The results showed that the MHD system has a higher possibility of its further development due to low unavoidable (36.82%) and high avoidable (63.18%) exergy desolation rates. The interlinkages among various units of the MHD system were found to be reasonably stronger due to the higher rate of exergy destruction of the endogenous type as compared to the exogenous portion. In the present study, the combustion chamber is found to have the highest possibility of upgradation as it possesses the largest value of avoidable exergy destruction rate together with the maximum rate of avoidable endogenous portion of the exergy destruction.
An Integrated Model for Sport Consumer Repurchase Intention: A case in the Commercial Martial Arts Schools
Authors: Liang Tanjian , Lei Ouyang , Ballard Paul , Fan Xiaoping
Published: June 2022

The retention of customers is fundamental to the success of sport organizations for a variety of reasons, not the least of which is it is less expensive for an organization to keep a current customer than to gain a new one. Since customer repurchase intention is an important indicator to predict repurchase behavior, exploring the factors that influence this behavior has important theoretical and practical implications in the commercial martial arts school market. Although previous research provides a foundation for the factors that influence a customer’s repurchase intention, additional empirical work is warranted. This study is designed to integrate the findings of previous studies and examine how utilitarian factors (perceived value and switching cost), a hedonic factor (perceived enjoyment), and social/psychological factors (confirmation and satisfaction) directly or indirectly influenced consumers’ repurchase intentions in the context of commercial martial arts schools. The results indicated that customer satisfaction had the strongest impact on customer repurchase intention, followed by perceived enjoyment, switching costs, confirmation, and perceived value.
Association between Teacher Candidates’ Competency and First-Year Employment in Physical Education: A Comparison Study
Authors: Chen YuChun , Myers Brian
Published: June 2022

Physical education teacher education (PETE) programs prepare teacher candidates to be competent and employed in P-12 school settings. This study examined the relationship between competency and first-year job obtainment in physical education (PE). Participants included 111 teacher candidates from two schools. Participants’ competency in content knowledge in Kinesiology and sub-disciplines (CKKH), content knowledge in sport and skill proficiency (CKSP) and pedagogical content knowledge (PCK) and first-year job obtainment in PE were collected. Descriptive statistics, independent-samples t tests, and multiple logistic regressions were used to analyze the data. The overall sample showed participants were most competent in PCK, followed by CKSP and CKKH. Female participants were more competent in PCK than their male counterparts, and those at School A performed better in CKSP and PCK than their peers at School B. As a sample, more than half of the participants (55.9%) obtained PE jobs. There was a significance between the overall sample and female participants’ competency in CKKH and their first-year employment in PE. This study was limited by sample size, variances in courses between the two schools, and by the defined timeline to clarify first-year PE employment. Implications regarding the importance of CKKH and first-year employment were discussed.
Islam and National Law: A Formal Legal Review on Sharia Laws in Aceh

Published: June 2022

The implementation of sharia in Aceh has gone through a democratic process subscribed by the Unitary State of the Republic of Indonesia. Nevertheless, some observers consider it problematic. Against this backdrop, this article discusses the principles of the formalization of sharia into positive law and further concretely analyses the case of formalization of sharia in Aceh. Employing a normative approach on research of law, this article shows that the principles of sharia codified in the qanuns of Aceh are grounded on the Qurʾān and the Sunna. The formalization of the sharia into the qanuns has gone through democracy and complies with the Indonesian law. Those qanuns contain regulations on ʿaqīda, muʿāmala, Islamic convocation, and Islamic criminal law.
