Authors: Jiang Wei
Published: February 2023

Using Maxwell finite element analysis software, the harmonic contents of no-load magnetic field and load magnetic field of three permanent magnet synchronous motors with 8 poles, 24 slots, 36 slots and 48 slots are calculated, and the radial force wave analysis is carried out. The influence of chute on cogging torque of integer slot motor and the influence of different pole arc coefficients and eccentricity of magnetic steel on sinusoidal distortion rate of magnetic field are analyzed. The analysis and calculation results show that, compared with fractional slot motor, the radial electromagnetic force and cogging torque of integral slot motor can be reduced more effectively by selecting the inclined slot and the appropriate magnetic steel shape, which provides a theoretical basis for reducing the vibration and noise of permanent magnet synchronous motor.

Authors: Qin Jiayin
Published: February 2023

ECG amplifier is widely used in medical monitoring system as a part of the transceiver circuit and sensors. For those who suffer from cardiovascular diseases, an ECG signal can reflect their heart conditions. This paper makes a research mainly on the design purpose of the ECG amplifier which includes low power consumption and high CMRR, and then presents the active load differential amplifier design to restrain the noise and to implement the function of amplify.  The design also displays how to maintain a balance between high DC gain and less distortion by setting the parameters. As is displayed in the figures, the ECG amplifier successfully removes the common-mode noise and achieves the ideal wave shape with the use of a software built-in calculator. The DC gain is about 60.55dB. When increases the DC gain with a fixed power consumption to 40dB, the wave shape will be a bit distorted. The design explains the application of the ECG amplifier into medical monitoring system in section 2 and proposes an example of ECG amplifier which can amplify and filter the original signal in section 3. Background knowledge, working process and measured results are given in this paper.

Enhance the Market Competitiveness of Electric Vehicles by Improving the Design of Lithium-ion Batteries
Authors: Chen Yuxin
Published: February 2023

Electric vehicles (EVs) are increasingly popular because they are energy efficient and capable of providing a good driving experience. However, the performance and market competitiveness of electric vehicles has been limited by a series of shortcomings, which are mainly caused by the limitations of the power source, lithium-ion batteries. To address these problems from the origin, this research analysed the causes of these problems and proposed some possible solutions based on the characteristics and working principles of lithium-ion batteries. The limitations of electric vehicles such as safety issues, low range, high cost, and limited life span are all proved to be related to the EV batteries. Lithium-ion batteries used by electric vehicles have the risk of fire and explosion when broken, overcharged, or exposed to high temperatures. The capacity and life span of them can easily be affected by different factors, which leads to the dissatisfaction of customers with the range and EV batteries’ life span. Furthermore, the production of lithium-ion batteries is very costly. Different ways to improve the performance of lithium-ion batteries are collected and evaluated. Finally, it is concluded that Li-S batteries and lithium titanate batteries are likely to become the solutions to what limited the development of electric vehicles. Since Li-S batteries and lithium titanate batteries still have some disadvantages, researchers should manage to tackle them in the future before they can be widely applied. This paper provides directions for the future development of EV batteries to improve the market competitiveness of electric vehicles.

Authors: Ji Jingya , Liu Yaming , Wang Yameng , Yao Wenjing
Published: February 2023

The limitations of traditional drug delivery vehicles include low specificity, uncontrolled biodegradation, and are oftentimes associated with toxicity and serious off-target events. In addressing the biological relevance of an effective drug delivery system in improving the therapeutic efficacy of active ingredients, a variety of new approaches for drug administration have recently been developed. Remarkable breakthroughs following the emergence of nanotechnologies promoted metal-organic frameworks (MOFs) as viable drug delivery possibilities. They are characterised by large surface area and porosities, and hence, exceptional drug adsorption ability. Inorganic MOFs in particular offer high drug loadings and functionalisation capacity, enabling a high-efficacy drug administration route and controlled pattern of drugs’ in vivo behaviours. This research encompasses the preparation of MOFs and their relevant drug delivery for different diseases treatment in biomedical field, which are classified according to four types of diseases including cancer, Alzheimer’s disease, pulmonary diseases, and ocular diseases. A diverse of different MOFs have been designed to treat given their corresponding properties for these diseases. Experimental outcomes from each research are also analysed to evaluate the therapeutic effectiveness and biological applicability of proposed MOFs, which is expected to provide a new idea for efficient drug delivery in disease treatment.

Authors: Fan Tingting , Yang Haokai , Che Feixiang , Zhou Mengying
Published: February 2023

The Dongdagou area of Yamansu in the southeastern margin of Turpan-Hami basin, which is located to the north of the Kangguertag collision zone, is one of the representative areas to discuss whether there is a Precambrian basement problem in the Junggar Turpan-Hami massif. As a consequence, zircon LA-ICP-MS U-Pb dating has been carried out for the shallow metamorphic tuffaceous fine sandstone in the Yamansu formation of the Lower Carboniferous in this area. The results show that the ages of 30 clastic zircons range from 365 ±3 Ma to 2451 ±39 Ma, with multi-peak distribution characteristics. The ages of clastic zircons are mainly concentrated in 365~496 Ma, the main peak is 365~436Ma, the secondary peak is 440~496 Ma, and the ages of 8 clastic zircons are between 765~2451 Ma. The study shows that the formation age of the sedimentary rock is not the early Carboniferous but the late Middle Devonian. Based on the isotopic dating data of the two-cloud quartz schist in the Xiaohuangshan area in the northeast of the study area, it is considered that the lower limit of the formation period of this set of strata is not earlier than the Devonian. Combined with the age data of ancient zircons in diabase and fused tuff in the study area, and the comprehensive analysis of regional sedimentary characteristics, it is concluded that there may be Precambrian crystalline basement in the sediment source area-Junggar-Turpan-Hami block.

Qualitative methods are used with historical approaches including heuristics, source verification, data interpretation and report writing. The Mantingan Mosque is a cross-cultural blend in Jepara society. The shape of the mosque which is tall and has steps in common with the punden terraces, a relic of the pre-literate era, namely the Megalithic era. On the roof of the mosque you can see the shape of a joglo like a traditional Javanese house, but at the end of the roof there is a pointed shape like a Chinese ethnic house. On the walls of the mosque there are also white stone carvings as the influence of Hindu-Buddhist and Chinese culture. This description explains that the Mantingan Mosque is a concrete example of a harmonious blend of cultures by the people of Jepara during the early days of the spread of Islam in Indonesia. Auliya Daeng Tomb is a historical site located not far from the Mantingan Mosque and Tomb. Auliya Daeng's grave site is located in Krapyak Village, Tahunan District, Jepara. The tomb has something in common with the presence of ancient brick construction in the tomb. Other forms of gravestones have Bugis, Aceh and Demak influences. This legacy indicates that Islam in Java developed long before Demak was founded. In addition, the discovery of Auliya Daeng's grave is a form of tolerance for the Indonesian people, who have always been diverse and multicultural.

Authors: Burrus M. Tyrrell , Werner Brian C. , Menendez Mariano E. , Denard Patrick J.
Published: February 2023

Despite the overall success of anatomic and reverse total shoulder arthroplasties (aTSA and rTSA), some patients continue to have or develop pain postoperatively. As the number of shoulder arthroplasties continues to increase in the United States, it is important that surgeons are able to recognize, diagnose, and treat the various pathologies. Some painful etiologies are specific to either aTSA or rTSA, and others can occur with both implant types. Infections, stiffness, neurologic syndromes, polyethylene wear, aseptic implant loosening, and metal allergies occur, regardless of implant choice. However, after an aTSA, subscapularis repair failure, superior rotator cuff tear, and joint overstuffing can result in shoulder pain. After a rTSA, specific causes of postoperative pain include instability, scapular notching, acromial or scapular spine fractures, subcoracoid pain, and neurologic injury. Regardless of the diagnosis, the surgeon must be methodical in the evaluation and, when appropriate, use blood work, advanced imaging studies, joint aspirations, shoulder arthroscopy, and nerve studies. Once diagnosed, appropriate treatment should be undertaken to resolve the cause of the pain or at least minimize the effect of the pain on the patient's outcome.

Introduction: Vascular Ehlers–Danlos syndrome (vEDS) is a connective tissue disorder weakening the vasculature. There is a perceived lack of awareness within the medical fraternity on this condition. This paper reviews contemporary evidence to enhance the understanding of this complex condition. Methods: A systematic review was performed. Inclusion criteria were studies in humans with a minimum of ﬁve patients. Exclusion criteria were laboratory or animal-based studies, reviews and studies not in English. A total of 115 papers were assessed with articles grouped into four categories: diagnosis, natural history, medical and surgery therapy. Results: The Villefranche criteria have a high sensitivity/negative predictive value for diagnosing EDS. Assessment of skin architecture/radiological investigation of large vessels can facilitate diagnosis. Genetic testing is available for the pathogenic COL3A1 variant. With regard to natural history, an overall review of 1,400 patients showed that age at diagnosis ranged from 4 to 40 years, age of death ranged from 28 to 54 years and vascular complications were frequent. The key medical therapy is celiprolol, which is associated with a reduction in arterial events three times greater with treatment than without. Non-operative therapy/non-invasive imaging techniques are suggested to be used when possible. Vessel reconstruction is possible but fragile tissue makes this challenging and endovascular interventions are ideally suited for the treatment of false aneurysms. There is a high rate of procedure-related complications (early and late). Conclusions: The poor natural history of vEDS means that accurate diagnosis is key to allow extension of complication-free periods. Vascular interventions are associated with high complication rates

The aim of our study was to investigate the features and agents in patients with dermatophytosis and to evaluate the dermatophyte flora changes in our area in recent years. Patients and Methods: Patients with dermatophytosis were included in our study. The age, gender, social life area, animal contact history of the patients and the clinical types of dermatophytosis were recorded. 443 native preparation positive species were cultured and their pathogens were investigated. There were 367 cases with an age range between 1-79 years. The animal contact history was present in 23,7% and rural area living anamnesis was present in 21.2% of the species having dermatophytosis diagnosis. The ratio of clinical type distributions were determined as follows; T.pedis %41.5, T.unguium on foot+hand %29.2, T.capitis %9.9, T.inguinalis %7.2, T.corporis %6.1, T.manum %3.6, T.facialis %2.0 and T.barba %0.5. The agent could be identified in 76.5% of the species with the rates of T.rubrum 62.5%, T.mentagrophytes 16.8%, T.verrucosum 9.4%, M.canis 4.7%, E.floccosum 3.2%, T.violaceum 1.8%, T.tonsurans 0.9%, M.nanum 0.3 % and T.schonlein 0.3 %. T.rubrum was the most frequent agent causing T.pedis, T.unguium, T.inguinalis. Also T.verrucosum was the most frequent agent in T.capitis, T.corporis and T.barba and it was considered that this could be arised from our animal husbandry region. There have been differentiations in dermatophytosis and their agents today versus their status in 20 years ago in our region. Although they were decreased in comparison to the past, cases with T. capitis have remained their importance at present.
A Numerical Method for Estimating Strut Forces in Multi-Braced Excavation Systems

Published: February 2023

The paper discusses the development of a numerical method for a multi-braced excavation to estimate strut forces. Two different software were used in the proposed method. Equivalent strut forces were calculated by plane strain analysis on Plaxis 2D. The number of Etabs models built corresponds to the number of strut levels. Loads acting on waler beams in these structural models were derived from the results of equivalent strut forces on the Plaxis 2D model. The results of the proposed method were compared with those of a full 3D analysis. This method ensures the force equilibrium with an error of less than 5% as compared with the total strut forces in the 3D calculation. Due to the corner effect not take into account, the corner strut internal forces in the proposed method are usually larger than those in the 3D analysis, while the internal forces of the middle struts seem to be the opposite. Although the differences have a wide variation, the average error is 35%. However, the results from the proposed method are conservative. The proposed method is useful for practicing engineers, especially in the primary design stage of multi-braced excavation with a complex-shaped plan.
Dynamic Behavior Analysis of the Bus with Two-stage Asymmetric Damper Using the Quarter Car Model Subjected to Transient Road Profile

Published: February 2023

The influences of two-stage asymmetric damper on the dynamic responses under transient road inputs in range of different vehicle velocities were investigated. This study’s purpose is to get full understanding of the dynamic behavior of the bus using the two-stage asymmetric damper. The body’s vibration acceleration, the tire dynamic load coefficient, and the suspension dynamic deflection were all analyzed to determine how much vibration was conveyed to the bus. By evaluating these criteria, this paper shows how the two-stage asymmetric damper affected an inner-city bus’s vibrational behavior. The transient input was employed in accordance with the GB/T 4970-2009 and IRC-99-1988 standards. For the purposes of the investigation, the two degrees of freedom quarter car model has been employed to carry out the simulation. According to the analysis's findings, a two-stage asymmetric damper maintains the better ride comfort level but offers the bus less handling stability and working space than a linear symmetric one.

Việc đột ngột đóng cửa các cơ sở giáo dục đại học trong đại dịch COVID-19 tại Việt Nam trong hai năm vừa qua đã khiến người học gặp khó khăn trong việc học tiếng Anh, đặc biệt là kỹ năng nói. Học tập và rèn luyện kỹ năng nói là rất quan trọng vì đó là phương thức giao tiếp chính trên toàn thế giới. Hầu hết các tổ chức giáo dục trên toàn thế giới đã áp dụng học trực tuyến trong giai đoạn dịch bệnh Covid-19. Giảng viên (GV) và sinh viên (SV) cần nhiều thời gian hơn để thích nghi với việc học trực tuyến vì phần lớn họ chưa quen với các công nghệ mới được sử dụng trong các lớp học nói trực tuyến. Vì vậy, bài báo này tìm hiểu đánh giá của GV và SV những vấn đề liên quan tới dạy - học trực tuyến trong lớp học kỹ năng nói tiếng Anh. Bài báo cũng xem xét những thách thức mà GV và SV gặp phải trong lớp học trực tuyến. Nghiên cứu sử dụng bảng câu hỏi có cấu trúc bao gồm nhận thức của GV và SV về dạy học trực tuyến tại hai trường đại học công nghệ kỹ thuật tại Thành phố Hồ Chí Minh, Việt Nam. Dữ liệu nghiên cứu được thu thập bằng cách phát bảng câu hỏi cho 20 giáo viên tiếng Anh và 100 SV. Phân tích dữ liệu được thực hiện bằng cách sử dụng các công cụ thống kê như giá trị trung bình và tỷ lệ phần trăm. Kết quả nghiên cứu cho chất lượng dạy và học kỹ năng nói tiếng Anh trong các lớp học trực tuyến chưa cao là do thiếu sự tương tác giữa GV và SV; kỹ năng công nghệ và kỹ năng học tập trực tuyến của SV còn hạn chế. Bên cạnh đó, bài báo đưa ra một số đề xuất để năng cao chất lượng dạy và học kỹ năng nói tiếng Anh trong các lớp học trực tuyến dựa trên kết quả khảo sát.
