Authors: Hu Sipin , Bao Shuhua , Shen Yuchen , Tu Mengyun
Published: July 2024

Deinagkistrodon acutus envenomation is one of the most common types of venomous snakebite in China and causes a series of envenomating effects on its victims. However, more specific information on the characteristics of D. acutus envenomation is rare in the English literature. Therefore, we aimed to give a detailed description of the epidemiological and clinical features of patients with D. acutus envenomation. Patients who were admitted with D. acutus envenomation between January 2018 and December 2021 were enrolled in this retrospective study. The data on demographics, clinical manifestations, laboratory features, management, and outcomes were collected. A total of 158 cases of D. acutus envenomation were enrolled. Men (n = 121; 76.6%) and rural populations (n = 133; 84.2%) were the high-risk groups, and most incidents (n = 141; 89.2%) happened between May and September. The specific effect was tissue necrosis at bite site, which occurred in 72 patients (45.6%). Other envenomation effects include extensive limb swelling, blistering, wound bleeding, and coagulopathy. In the envenomed patients, 155 (98.1%) received antivenom, 47 (29.7%) needed operations, 20 (12.7%) required intensive care, and one died. Deinagkistrodon acutus envenomation is a common snakebites emergency in Hangzhou area. A high rate of tissue necrosis at bite site and venom-induced consumption coagulopathy are the characteristics of D. acutus envenomation. Although the mortality rate is low, some patients still require intensive care.

Published: July 2024

In order to improve the efficiency of passenger cars, developments focus on decreasing their aerodynamic drag, part of which is caused by cooling air. Thus, car manufacturers try to seal the cooling air path to prevent leakage flows. Nevertheless, gaps between the single components of the cooling air path widen due to the deformation of components under aerodynamic load. For simulating the cooling airflow utilization ratio (CAUR), computational fluid dynamics (CFD) simulations are used, which neglect component deformation. In this paper, a computational method aiming at sufficient gap resolution and determining the CAUR of passenger cars under the consideration of component deformation is developed. Therefore, a partitioned approach of fluid structure interaction (FSI) simulations is used. The fluid field is simulated in OpenFOAM, whereas the structural simulations are conducted using Pam-Crash. In order to validate the simulation results, the CAUR of a battery electric and an internal combustion engine powered vehicle is determined at a specifically developed cooling air test rig. Additionally, wind tunnel measurements determining wall pressures and component deformations are conducted. Furthermore, an experimental method was developed to measure three-dimensional deformations applying the “Structure from Motion” method to phosphorescent marker points. It could be shown, that areas of deformation can be detected by the developed simulation method and that the deformations negatively influence the CAUR. Comparing the results of the FSI simulations to single CFD simulations, this work was able to reduce the maximum estimation error of the CAUR from +12 %P to +3 %P. Finally, remaining error sources are outlined.

Published: July 2024

Investigating human driver behavior enhances the acceptance of the autonomous driving and increases road safety in heterogeneous environments with human-operated and autonomous vehicles. The previously established driver fingerprint model, focuses on the classification of driving styles based on CAN bus signals. However, driving styles are inherently complex and influenced by multiple factors, including changing driving environments and driver states. To comprehensively create a driver profile, an in-car measurement system based on the Driver-Driven vehicle-Driving environment (3D) framework is developed. The measurement system records emotional and physiological signals from the driver, including the ECG signal and heart rate. A Raspberry Pi camera is utilized on the dashboard to capture the driver's facial expressions and a trained convolutional neural network (CNN) recognizes emotion. To conduct unobtrusive ECG measurements, an ECG sensor is integrated into the steering wheel. Additionally, the system accesses CAN bus signals from the vehicle to assess the driver’s driving style, extracting signals related to longitudinal and lateral control behavior from the Drive-CAN (A-CAN). Recognizing that variables from the driving environment can influence driving style, such as traffic signs and road conditions, a windshield-mounted webcam is integrated into the measurement system. This setup enables real-time detection of common traffic signs and assessment of road conditions, distinguishing between dry, wet, or icy road surfaces. Augmenting of the image data from camera, signals from in-car ADAS-sensors, such as the distance measured by the front radar in relation to neighboring vehicles, are integrated for a comprehensive analysis of driving style. The established measurement system is presently implemented in a test vehicle, poised to investigate the interplay between the 3D-parameters, with a focus on driving style of human driver.

Published: July 2024

With the automotive industry’s increasing focus on electromobility and the growing share of electric cars, new challenges are arising for the development of electric motors. The requirements for torque and power of traction motors are constantly growing, while installation space, costs and weight are increasingly becoming limiting factors. Moreover, there is an inherent conflict in the design between power density and efficiency of an electric motor. Thus, a main focus in today’s development lies on space-saving and yet effective and innovative cooling systems. This paper presents an approach for a multi-physical optimization that combines the domains of electromagnetics and thermodynamics. Based on a reference machine, this simulative study examins a total of nine different stator cooling concepts varying the cooling duct positions and end-winding cooling concepts. To ensure the highest possible comparability, the rotor geometry as well as the overall dimensions in terms of outer diameter and length of the electric machine remain unchanged. The stator design is slightly adjusted to achieve same maximum torque and winding cross-section. Initially, the electromagnetic effects of various cooling slot positions are investigated and compared with respect to efficiency and individual loss distribution. Subsequently, the thermal performance is analyzed by means of fluid-dynamical simulations to quantify the heat transfer and assess the cooling effectivity. Eventually, these results are merged in a lumped parameter thermal network model. Accounting for both the distinguished electromagnetic and thermal benefits and disadvantages, a final study is presented evaluating the continuous power capability of the different concepts at equal boundary conditions.
Harmonic Injection Method for NVH Optimization of Permanent Magnet Synchronous Motors Considering the Structural Characteristics of the Machine

Published: July 2024

Noise, vibration and harshness (NVH) is one of the most important performance evaluation aspects of electric motors. Among the different causes of the NVH issues of electrical drives, the spatial and temporal harmonics of the electrical drive system are of great importance. To reduce the tonal noise of the electric motors induced by these harmonics, harmonic injection methods are applied in many applications. However, a lot of existing researches focus more either on improving the optimization process of the harmonic injection parameter settings, or on the controller design of the harmonic injection process, while the structural dynamic characteristics of the motor are seldom considered. A lot of literature shows that the harmonic injection strategies can more effectively influence the mode 0 (M0) radial forces than the higher spatial orders, so it is more efficient to apply such methods at the frequencies/orders where the effect of mode 0 forces are dominant with respect to the surface vibration or acoustics of the motor. In this paper, a guideline is proposed for the design and optimization of current harmonic injection strategies, where a 2-dimensional linear transfer function is computed to quantify the contributions of different force modes and it is used as the reference for the harmonic injection control settings. The proposed method is tested and validated with the multi-physics co-simulation of a finite-element model for an interior permanent magnet synchronous motor (IPMSM), where the influence of the inverter and pulse width modulation (PWM) are also considered and analyzed. The simulation results show that the proposed scheme can effectively reduce the surface vibration (~1.5dB) at the chosen sensor location without deteriorating the torque output performance of the IPMSM model.

Published: July 2024

Nowadays, green hydrogen can play a crucial role in a successful clean energy transition, thus reaching net zero emissions in the transport sector. Moreover, hydrogen exploitation in internal combustion engines is favored by its suitable combustion properties and quasi-zero pollutant emissions. High flame speeds enable a lean combustion approach, which provides high efficiency and reduces NOx emissions. However, high airflow rates are required to achieve the load levels typical of heavy-duty applications. In this framework, the present study aims at investigating the required boosting system of a 6-cylinder, 13-litre heavy-duty spark ignition engine through 1D numerical simulation. A comparison among various architectures of the turbocharging system and the size of each component is presented, thus highlighting the limitations and potentialities of each architecture and providing important insights for the selection of the best turbocharging system.
COVID-19, mother-teachers and teen suicide-personality disorder: Exploring the synergies and readying for contingencies in Indigenous-Christian contexts
Authors: Museka Godfrey , Hlatywayo Anniegrace Mapangisana
Published: July 2024

The emergence of COVID-19 affected all facets of life. Lockdown restrictions, introduced in various countries, meant the majority of people had to stay home in the interests of social distancing. Schools and other learning institutions in Zimbabwe and elsewhere were closed and the phenomenon of home-schooling was introduced to ensure that learners do not lag behind. Home-schooling meant that in addition to the parenting role, parents- in particular mothers, had to become teachers. The impact of this sudden change of roles on the mental health of mothers and teen suicide, a form of borderline personality disorder, is yet to be studied. Is the growing scourge of teen suicide in Zimbabwe a result of COVID-19 inspired home-schooling experiences? Data solicited through face-to-face interviews and documents analyses and analysed through the lens of family systems theory seem to suggest that family disruptions and most mothers’ terrible experience with home-schooling was in part responsible for children’s (learners’) suicide ideation. To this end, we suggest that when teen education and child development catastrophe in the mould of COVID-19 occurs, manuals and toolkits on home-schooling should be developed to guide parents and children.
On the Satisfiability of Local First-Order Logics with Data
Authors: Bollig Benedikt , Sangnier Arnaud , Stietel Olivier
Published: July 2024

We study first-order logic over unordered structures whose elements carry a
finite number of data values from an infinite domain. Data values can be
compared wrt.\ equality. As the satisfiability problem for this logic is
undecidable in general, we introduce a family of local fragments. They restrict
quantification to the neighbourhood of a given reference point that is bounded
by some radius. Our first main result establishes decidability of the
satisfiability problem for the local radius-1 fragment in presence of one
"diagonal relation". On the other hand, extending the radius leads to
undecidability. In a second part, we provide the precise decidability and
complexity landscape of the satisfiability problem for the existential
fragments of local logic, which are parameterized by the number of data values
carried by each element and the radius of the considered neighbourhoods.
Altogether, we draw a landscape of formalisms that are suitable for the
specification of systems with data and open up new avenues for future research.

Authors: Domingues Inês , Campos Carlos , Siopa Jorge
Published: July 2024

A análise postural e o estudo das alterações posturais têm especial importância no âmbito da prática desportiva, pois a ocorrência de alterações posturais induz o aumento de lesões e reduz o rendimento desportivo dos atletas. No entanto, a nível nacional, este tipo de estudo é pouco frequente e a sua divulgação é praticamente inexistente. Assim, na sequência de uma parceria entre a Coordenação do Curso de Licenciatura em Biomecânica da ESTG\IPL1 e o clube de atletismo Juventude Vidigalense, foi realizada uma análise postural a 7 atletas de atletismo de alta competição. A análise postural teve por objetivo caracterizar o perfil postural dos atletas, identificando as alterações posturais que conduzem à ocorrência de lesões e a sua influência no rendimento desportivo dos mesmos. Assim, para cada atleta foi elaborada uma ficha na qual se apresenta a sua composição corporal, que resulta de um rigoroso estudo antropométrico, e a sua análise postural, baseada na técnica de fotogrametria. Os resultados foram obtidos e confirmados com o apoio dos softwares Physical Test® e SAPO® (Software de Avaliação Postural). As fichas de caracterização de cada atleta permitiram apresentar um conjunto de recomendações aos elementos do clube, em particular aos respetivos treinadores, fomentando o reajuste do treino dos atletas com vista a minimizar o impacto dos desvios posturais encontrados.
Aprendizagem de competências empreendedoras: paradoxos no processo de aprendizagem
Authors: Kakkonen Marja-Liisa
Published: July 2024

A finalidade do estudo longitudinal foi averiguar até que ponto que as competências empreendedoras dos estudantes se desenvolveram no programa de aprendizagem de atribuição de grau. O estudo analisou as perceções dos alunos através de uma mistura de métodos diferentes de pesquisa. Seis estudos foram realizados no total. Neste trabalho, apenas os resultados de três deles são discutidos e os resultados são discutidos de um ponto de vista dos paradoxos do processo de aprendizagem. Os resultados indicaram que os perfis de competência e intenções empreendedora já estão inter-relacionados no início dos estudos. Além disso, os objetivos de aprendizagem do programa de ensino de atribuição de grau são realistas para o alcance dos alunos do primeiro ano. Aí reside o primeiro paradoxo: é esperada a autorregulação na aprendizagem e no entanto, os alunos podem não ter as habilidades para a aprendizagem autodirigida e estratégias de aprendizagem metacognitivas. Em segundo lugar, uso da criatividade é esperado em certa medida, mas os alunos não suficientemente são encorajados e apoiados por professores. Em terceiro lugar, as atitudes empreendedoras dos estudantes foram bastante positivas, no entanto, as atitudes permaneceram estáveis ou diminuíram durante os estudos. Em quarto lugar, o programa de ensino de atribuição de grau teve uma influência positiva no desenvolvimento de competências de negócio, mas não na intenção empreendedora. Pode concluir-se que há uma necessidade de mudanças na pedagogia e no ambiente de aprendizagem, se o objetivo é promover mais as competências empreendedoras dos alunos e aumentar a criação de negócios.

Authors: Poças Ana
Published: July 2024

Este trabalho tem por principais objectivos evidenciar as relações de causalidade entre capital humano, produtividade e crescimento, para além de mostrar como problemas de saúde, e em particular aqueles que afectam mais significativamente os países mais desenvolvidos, se traduzem numa perda importante de potencial humano e económico. Neste sentido, analisamos o impacto e a magnitude de um maior nível de educação e do estado de saúde da população sobre o crescimento do rendimento per capita dos países da OCDE e da UE. Recorrendo a um modelo de dados em painel para o período 1980–2004 e à metodologia de efeitos fixos, concluímos que a inclusão de variáveis de saúde que reflectem problemas de saúde crónicos acrescentam poder explicativo ao modelo de crescimento, tendo um efeito negativo e estatisticamente significativo.

Published: July 2024

In Iran’s higher education English language teaching (ELT) context, we explored the moral nuances embedded in two conversation courses offered to undergraduate students majoring in English Literature at one of the branches of the Islamic Azad University (IAU) in Tehran. We collected data through classroom observations, field notes, and semi-structured individual and focus group interviews. Our content analysis revealed a range of moral values embedded in significant incidents, which we categorized into five themes: (a) relations, (b) rules and regulations, (c) assessment, (d) curricular substructure, and (I) culture. These themes were further subcategorized into more specific concepts that emerged from our data. We selectively focused on two subthemes, Class Initiation and Turn Taking, as well as the main theme of Assessment, as these were the most morally loaded, with a higher frequency of moral values extracted from related class episodes compared to other categories. This selection allowed for a deeper exploration of the complexities and nuances within these themes, providing further support on the role of ELT teachers as moral exemplars for their students.

Abstract: This research focuses on the erosion wear behaviour of two Fe-Cr-C alloys with similar chemical compositions obtained using different production methods. The first alloy belongs to the high chromium cast irons (HCCI). It was made by casting, after which the samples were heat treated by annealing. The second alloy in the form of the coating was applied by the plasma transferred arc (PTA) surface welding process at the substrate material (structural carbon steel). Damage to the components of industrial plants due to erosive and/or abrasive wear is a frequent cause of failure and outages of such systems. For this reason, and to bring the experimental research closer to real service conditions, an erosion test was performed at a gas blast sand facility with a high erodent speed of 90 m/s and a higher feed rate than standard erosion testing parameters recommended in ASTM G76 standard. Microstructural characterisation of all samples was done using a scanning electron microscope (SEM). The X-ray diffraction analysis (XRD) was used to identify the phases present. Similar erosion mechanisms were observed on all tested specimens, but coated samples (PTA alloy) had a lower mass loss during the erosion test compared to cast samples (HCCI alloy), i.e. they showed better erosion resistance.

Background. The gastric neuroendocrine tumours (G-NETs), arising from neuroendocrine cells within the stomach. Type I lesions are associated with chronic atrophic gastritis (CAG). Multiple G-NETs are rare. Purpose – of our report is to describe a rare case of multiple Type-I G-NETs. Material and methods. During routine gastroscopy in a 44-year-old female with history of CAG and anaemia, multiple (15–20) polyps of size 2–9 mm were found. Multiple biopsies were obtained. Histopathological examination with haematoxylin and eosin staining described these lesions as undifferentiated cancer. Repeated gastroscopy was done. The three biggest polyps (5–9 mm) were removed by snare polypectomy. Repeated histopathological examination was specific for G-NET. The neoplasm presented Ki-67 proliferation index of < 3%; Cytokeratin 18, Chromogranin A, Synaptophysin, INSM1 were positive in neoplasm cells. Laparoscopic total gastrectomy was done. The operative time was 255 min, and the blood loss was 50 ml. Histopathological examination of a surgical specimen revealed multiple, Grade 1 G-NET (fig. 1–3). All lesions are limited to the mucosa and submucosa of the stomach, the longest size of the largest tumour lesion is 5 mm, what corresponds to pT1(m). No signs of lymphovascular or perineural invasion were found (L0 V0 Pn0). 18 regional lymph nodes were examined, no metastases were detected (0/18, pN0). Edges of resections of the esophagus and duodenum without signs of tumour growth (R0). Outside of tumours, there were signs of chronic inflammation of the stomach mucosa, with intestinal metaplasia and mixed glandular atrophy, there are also foci of nodular hyperplasia of neuroendocrine cells. Conclusion. We reported a rare case of multiple type-I G-NETs (pT1N0M0) with pernicious anaemia due to autoimmune CAG. Laparoscopic total gastrectomy is a method of choice in treatment of such patients.

Analisis Kelayakan Investasi Modifikasi Konveyor dan Dermaga Bongkar Muat Batu Bara PLTU Sebalang 2 x 100 MW
Authors: Septian Azwar , Utomo Raissa Safira , Reza Alfian Muhammad
Published: July 2024

PLTU Sebalang merupakan pembangkit listrik milik PT PLN (Persero) dengan kapasitas 2 x 100 MW. Pembangkit ini merupakan salah satu andalan kelistrikan untuk sistem sumatera bagian selatan. Pembangkit ini beroperasi sejak tahun 2012. Dengan kapasitas 200 MW kebutuhan batubara yang diperlukan adalah 144,000 ton / bulan. Pembangkit ini mendapat supplai bahan bakar batu bara melalui jetty yang didesain untuk kapal 10,000 DWT. Diperlukan 15 kali trip kapal 10,000 DWT dalam sebulan atau sekitar 3-4 kapal perminggu untuk mencukupi kebutuhan PLTU dalam sebulan. Sistem pembongkaran batu bara dari dermaga menuju PLTU hanya memiliki 1 jalur conveyor dengan kecepatan rata-rata 200-300 ton per jam. Kondisi ini mengakibatkan bongkar muat untuk 1 kapal tongkang memerlukan waktu 2,5 – 3 hari, jika dibiarkan tanpa ada penanganan PLTU akan kehabisan bahan bakar. Untuk mengatasi kekurangan batubara, PLTU Sebalang menyewa armada truk dan dermaga milik PEMDA setempat untuk membantu bongkar muat dan pengangkutan batu bara dengan biaya masing-masing Rp 15.000/ton dan Rp 20.000/ton untuk separuh dari total pengiriman. Diperlukan solusi seperti investasi untuk modifikasi jalur konveyor batu bara dan ship unloader pada dermaga PLTU dengan kapasitas yang lebih baik dari eksisting untuk mempercepat pembongkaran dan batu bara. Untuk memastikan bahwa investasi yang dilakukan layak, maka perlu dilakukan analisis kelayakan investasi yang pada studi ini digambarkan oleh perhitungan NPV, IRR, dan Payback Period (PP). Terdapat dua opsi investasi, yaitu, opsi dengan kehandalan sedang atau opsi 1 dan opsi dengan kehandalan tinggi atau opsi 2. Opsi 2 memiliki nilai investasi yang lebih besar yaitu 240 miliar rupiah atau 35 miliar lebih tinggi dari opsi 1. Berdasarkan hasil analisis finansial, opsi 1 memiliki nilai NPV adalah 671,6 miliar rupiah. Kemudian nilai IRR yang didapat adalah 19,16% dimana lebih besar dari nilai WACC yang ditetapkan yaitu 9,5%. Investasi yang dikeluarkan memiliki PP pada tahun kelima. Untuk opsi 2 nilai hasil perhitungan finansial sedikit bergeser menjadi 636,6 miliar rupiah, 15,06% IRR, dan PP pada tahun keenam. Penggunaan opsi 1 akan lebih baik secara finansial jika dilihat dari parameter NPV, IRR, dan PP. Namun demikian, terkait dengan mitigasi risiko kegagalan operasi, opsi 2 adalah pilihan yang tepat. Perlu diketahui dalam kasus kegagalan operasi, akan timbul adanya biaya tambahan untuk melakukan perbaikan.

Penelitian ini dilatarbelakangi adanya penataan lemari dan barang pada gudang Politeknik Sinar Mas Berau Coal (Poltek Simas Berau) yang saat ini kondisinya belum tertata dengan rapi sehingga membuat kapasitas gudang belum dapat dimanfaatkan secara optimal sehingga terjadi penurunan kapasitas gudang yang sebenarnya. Penataan lemari yang tidak rapi membuat jarak untuk mencari barang/material mengalami kesulitan dan jaraknya jauh dari pintu utama. Dengan pergerakan barang yang cepat (fast moving) dapat menghambat kelancaran aktivitas keluar masuknya barang. Tujuan peneletian ini adalah untuk menganalisa gudang Poltek Simas Berau sesuai dengan FSN (fast, Slow, Non moving), me-relayout gudang Poltek Simas Berau dan meminimalkan jarak material handling serta meningkatkan kelancaran aksesibilitasnya. Penelitian ini menggunakan metode class based storage dengan pendekatan kuantitatif. Menggunakan analisis FSN dengan perhitungan TOR (Turn Over Ratio) serta analisis material handling. Hasil penelitian menunjukkan adanya layout gudang Poltek Simas Berau saat ini masih terdapat barang yang termasuk non-moving dimana terletak dekat dengan pintu masuk/keluar sehingga menghalangi kegiatan pengambilan barang. Pada hasil layout usulan barang dikelompokkan kedalam 5 tempat penyimpanan dimana dari enam (6) tempat penyimpaan saat ini akan dijadikan satu dengan barang fast moving yaitu kertas HVS. Keseluruhan penempatan telah dianalisis dengan menggunakan analisis FSN berdasarkan TOR dan meminimalkan jarak termpuh terhadap pintu keluar/masuk sebanyak 3,64 meter. Total jarak material handling sebuah area penyimpanan pada gudang Poltek Simas Berau berdasarkan perhitungan TOR pada layout gudang saat ini adalah 116,45 meter. Hasil layout gudang usulan jarak material handling berdasarkan perhitungan TOR adalah 858 meter yang artinya relayout gudang menggunakan metode class based storage dapat mengurangi jarak material handling sebesar 304,45 meter atau sebesar 26,13%.

Riset ini bertujuan untuk mengeksplorasi variabel-variabel pengaruh kualitas audit serta menganalisis peran fee audit dalam memperkuat atau memperlemah kualitas audit, yang diukur dengan akrual diskresioner. Sampel penelitian meliputi perusahaan sektor energi Indonesia yang tercantum di Bursa Efek periode 2019-2023, dengan pengambilan sampel non probabilitas menggunakan pertimbangan tertentu. Data dianalisis menggunakan Eviews 12 dengan teknik Moderate Regression Analysis (MRA). Hasil riset memperlihatkan bahwa kualitas audit tidak dipengaruhi secara signifikan oleh audit tenure dan reputasi auditor. Selain itu, hubungan antara audit tenure dan reputasi auditor dengan kualitas audit juga tidak dimoderasi oleh fee audit. Penelitian ini memberikan wawasan bahwa meskipun audit tenure dan reputasi auditor dianggap penting, keduanya tidak memiliki dampak signifikan pada kualitas audit dalam konteks perusahaan energi di Indonesia, dan fee audit tidak mempengaruhi hubungan tersebut. Temuan ini memberikan kontribusi penting bagi literatur audit dan praktik akuntansi, khususnya dalam konteks pengawasan kualitas laporan keuangan di industri energi.

The Impact of Monetary Policy on Economic Growth in Vietnam
Authors: Hung Dao Van ,   Academy of Policy and Development, Hanoi City, Vietnam
Published: July 2024

This article focuses on investigating the impact of monetary policy on economic growth in Vietnam in both the short and long term using the Vector Error Correction Model (VECM) over the period from 2005 to 2023. The research results indicate that, in the long term, both M2 money supply and exchange rates have a positive impact on economic growth. Among these, the influence of the M2 money supply on growth is greater than that of exchange rates, suggesting that adjustments in the M2 money supply allow for immediate and comprehensive effects on the economy compared to adjustments in exchange rates. Conversely, real interest rates have an inverse effect on GDP in the long term.
