Further Investigations into the Benefits and Challenges of Eliminating Port Overlap in Wankel Rotary Engines
Authors: Turner James , Turner Matthew , Islam Reza , Shen Xuankun , Costall Aaron
Published: May 2021

In a previous study it was shown that a production vehicle employing a Wankel rotary engine, the Mazda RX-8, was easily capable of meeting much more modern hydrocarbon emissions than it had been certified for. It was contended that this was mainly due to its provision of zero port overlap through its adoption of side intake and exhaust ports. In that earlier work a preliminary investigation was conducted to gauge the impact of adopting a zero overlap approach in a peripherally-ported Wankel engine, with a significant reduction in performance and fuel economy being found.

The present work builds on those initial studies by taking the engine from the vehicle and testing it on an engine dynamometer. The results show that the best fuel consumption of the engine is entirely in line with that of several proposed dedicated range extender engines, supporting the contention that the Wankel engine is an excellent candidate for that role. Also, continued 1-D modelling of the zero overlap peripherally-ported engine has shown that a potential route to regain lost performance and better fuel economy is to turbocompound the engine.

While compounding using turbomachinery provides one direction for further work, a new concept is proposed which uses the conventional three-flank Wankel rotor in its two-lobe housing to provide a positive displacement compounder to enable zero overlap anywhere in the device. This will allow the potential to configure large unobstructive ports with unimpeded timing. This novel concept is discussed in the paper.

Electrification of heavy-duty trucks has received significant attention in the past year as a result of future regulations in some states. For example, California will require a certain percentage of tractor trailers, delivery trucks and vans sold to be zero emission by 2035. However, the relatively low energy density of batteries in comparison to diesel fuel, as well as the operating profiles of heavy-duty trucks, make the application of electrified powertrain in these applications more challenging. Heavy-duty vehicles can be broadly classified into two main categories; long-haul tractors and vocational vehicles. Long-haul tractors offer limited benefit from electrification due to the majority of operation occurring at constant cruise speeds, long range requirements and the high efficiency provided by the diesel engine. However, vocational applications can realize a significant benefit from electrified powertrains due to their lower vehicle speeds, frequent start-stop driving and shorter operating range requirements.

As the heavy-duty industry deals with solving challenges around the application of electrified powertrains, there are multiple pathways that can be explored to meet future regulatory requirements. This paper is the second part of a two-paper series that focuses on evaluating electrified solutions for Class 6-7 medium heavy-duty vehicles in the 2027 and beyond time frame. Using a model-based approach, this paper presents a comprehensive analysis that compares the baseline diesel powertrain against multiple alternative powertrain configurations. These configurations include, an optimized parallel diesel hybrid, all-electric, diesel range extender, gasoline range extender, Compressed Natural Gas (CNG) range extender, and fuel cell range extender; which are evaluated on the basis of cost of ownership, fuel efficiency, emissions, payback period, lost payload opportunity, range, and battery life. The analysis shows that for a near-term less-disruptive scenario wherein the conventional diesel powertrain layout is preserved, a 48V P3 parallel hybrid vehicle configuration is the most cost-effective solution, while for a near-term more-disruptive scenario, the Internal Combustion Engine (ICE) based Range Extender Electric Vehicles (REEVs) have the most potential to reduce greenhouse gas emissions while achieving lower cost of ownership than the baseline vehicle. For a longer-term and more-disruptive scenario, the all-electric vehicle configuration can achieve parity with the baseline vehicle cost of ownership provided the vehicle driving range requirement is limited to 100-150 miles. The analysis further highlights that the overall benefit of an all-electric powertrain solution depends significantly on the future battery technology advancements and vehicle range requirements.

This retrospective cohort study uses survival analysis to estimate the effectiveness of Toyota ADAS in helping prevent system-relevant crashes. Toyota production data were merged with police reported crash files from eight U.S. states for crash years 2015 up to 2019 by 17-digit vehicle identification number (VIN). System-relevant crash scenarios included: striking vehicle in front-to-rear, single vehicle run-off-the-road, same-direction sideswipe, head-on, and pedestrian struck. The study vehicle cohort included 11 Toyota/Lexus models, model years 2015 through 2018, sold in the eight study states. ADAS technologies studied included automatic emergency braking (AEB), lane departure warning (LDW), lane keeping assistance (LKA), blind spot monitoring (BSM) and pedestrian automatic emergency braking (PedAEB). Among the study cohort of 2,394,913 vehicles, police reported 308,490 crashes. The crude crash rate ratio (CRR) was 0.61 for AEB-equipped versus non-equipped vehicles. However, the CRR does not adjust for differences in ADAS-equipped versus non- equipped vehicles. To adjust for group differences (confounding factors), Cox proportional-hazards (CPH) regression modeled the relative risk (hazard ratio, HR) of being in a system-relevant crash for vehicles with versus without the ADAS. CPH modeling found that AEB-equipped vehicles were 43% less likely (HR=0.57) to be the striking vehicle in a front-to-rear crash compared to non-equipped vehicles. The analysis was also stratified to look at the effect in intersection versus non-intersection crashes. BSM-equipped vehicles were 4% less likely (HR=0.96) to be involved in a same-direction sideswipe, though the differences were not significant (p=0.252). LKA-equipped vehicles were 9% less likely (HR=0.91) to run off the road. LDW and LKA did not have a significant effect on risk of same-direction sideswipe or head-on crash. PedAEB-equipped vehicles were less likely to hit a pedestrian (HR=0.84), but the hazard ratios were marginally significant (p=0.114). This study contributes new evidence of the effectiveness of ADAS in helping prevent system-targeted crashes.

Published: May 2021

Every day in the United States, an average of approximately two cyclists die in bicycle accidents. Sometimes, forensic engineers are asked to reconstruct these accidents. These cyclists may use bicycle GPS devices to record important data, which they use to monitor their riding activities. By analyzing this data, many questions can be answered regarding various parameters such as speed, position, and riding behavior of the bicyclist.

The goal of this study was to analyze the accuracy of the GPS position and speed data. For this study, four different bicycle GPS devices (one of which was paired with a magnetometer Garmin Bicycle Speed Sensor), a GoPro camera equipped with GPS, and a smartphone recording to Strava, were mounted on a bicycle. The bicycle was ridden in an approximately straight line (back and forth), and then around a building, to measure positional and speed accuracy. Additionally, the bicycle was ridden in a straight line, then decelerated to a complete stop for varied durations, and then accelerated forward. This was done to see if the retrieved data showed the bicycle coming to a complete stop, or if the GPS averaged a few data points showing that the rider never came to a stop. Furthermore, the bicycle was stopped at a specific location for a certain duration and the GPS drift of each device was studied.

Using VBOX 3i RTK DGPS positional data as the reference, test data revealed that all six bicycle test devices had relative error in positional and speed data. The Garmin Edge 530 had an average speed error of 10.83% and positional error of 21.78 ft. The Garmin Edge 1000 (BSS) had an average speed error of 4.71% and positional error of 15.2 ft. The Lezyne Mega XL had an average speed error of 3.5% and positional error of 4.82 ft. The Wahoo ELEMNT Bolt had an average speed error of 3.53% and a positional error of 10.46 ft. The Strava app had a positional error of 11.45 ft. The GoPro Hero5 had an average speed error of 5.05% and a positional error of 4.79 ft.
Single embryo transfer in all infertile couples treated with assisted reproduction produces excellent results and avoids multiple births
Authors: De Geyter Christian
Published: May 2021

Assisted reproductive technology (ART) is an efficacious and frequently used treatment of infertility. Multiple births resulting from the widespread practice of transfer of more than one embryo per treatment trial have reached epidemic proportions. Since the revision of the Swiss law on ART in September 2017, up to 12 embryos per couple may now be developed in vitro and cryopreserved in Switzerland. This potentially allows for the selection and transfer of only one embryo to avoid multiple birth with ART. We decided to offer transfer of one embryo to all infertile patients undergoing ART in our institution. In this retrospective cohort study the cumulative pregnancy and live-birth rates after universal transfer of one embryo from January 2018 to December 2019 were analysed. The cumulative pregnancy rate per oocyte collection and up to five transfer cycles was as high as 48.9%, whereas the cumulative live-birth rate reached 33.4% and none were multiple births. These results were age-dependent, with best outcome in patients aged 37 years or younger. When still remaining cryopreserved embryos were taken into account, the cumulative birth-rates could exceed 60% per oocyte collection in all age groups. The consequent adoption of a single embryo transfer significantly reduced the incidence of multiple births in the department of obstetrics and the number of prematurely born infants resulting from multiple pregnancies in the department of neonatology. Universal elective single embryo transfer is feasible in Switzerland, benefits infertile couples treated with ART and reduces the number of multiple births in obstetrics and of newborn children hospitalised into neonatal care.

Published: May 2021

Preterm Birth (PTB) can negatively affect the health of mothers as well as infants. Prediction of this gynecological complication remains difficult especially in Middle and Low-Income countries because of limited access to specific tests and data collection scarcity. Machine learning methods have been used to predict PTB but the low prevalence of this pregnancy complication led to rather low prediction values. The objective of this study was to produce a nomogram based on improved prediction for low prevalence PTB using up sampling and lasso penalized regression. We used data from a cohort study in Northern Lebanon of 922 multiparous presenting a PTB prevalence of 8%. We analyzed the personal, demographic, and health indicators available for this group of women. The improved Positive Predictive Value for PTB reached around 88%. The regression coefficients of the 6 selected variables (Pre-hemorrhage, Social status, Residence, Age, BMI, and Weight gain) were used to create a nomogram to screen multiparous women for PTB risk. The nomogram based on readily available indicators for multiparous women reasonably predicted most of the at PTB risk women. The physicians can use this tool to screen for women at high risk for spontaneous preterm birth to improve medical surveillance that can reduce PTB incidence.

The research method is qualitative with a theory research action combination with phenomenological approach. The research design using multi-site involving six locus in South Kalimantan, Indonesia. Data collection techniques used were content analysis, participatory observation and depth interviews. The analysis used in answering this research is a combination of various analytical methods to answer each of the objectives namely miles & Huberman analysis, BAPenas MAPP Analysis, Siagian Leadership Role Analysis and Webbed Spider Model Analysis as the ultimate in formulating green leadership models in the management of natural resources and sustainable environment. This study aims to observe, study and find events related to the focus of research to get the formulation of a model of green leadership in the management of natural resources and the sustainable environment that appears naturally. The results of this research found that the Green Leadership Model’s has the criteria : has an understanding of environmental issues, response to policies, community accessibility, institutional support, commitment to environmental sustainability, has innovation that is pro to the environment and an optimal role for leaders in the management of natural resources and sustainable environment. These included the following; in the past experience, sustainable management of natural resources and the environment around the Meratus mountains is strongly influenced by the leadership role both formally and informally. Sustainability of natural resource management and sustainable environment is strongly influenced by leadership who: has awareness and love for the environment, provide motivation through direct implementation to the community through policies that are implemented in maintaining environmental sustainability, provide broad access for the community to participate in the management of natural resources and the environment which experiences a lot of quality degradation ; firm and able to refuse in responding to the demands of the business world which focus on increasing profits alone to exploit natural resources and the environment; and has criteria as an environmentally friendly leadership model in accordance with the criteria needed as an ideal description of leadership. Green leadership models in the management of natural resources and the environment come from formal and informal leadership. The formal green leadership comes from the Regional / Institution / Institution of government, while the informal green leadership comes from the customary leadership that carries out customary rules that do not conflict with government regulations in the management of natural resources and the sustainable environment.

Published: May 2021

Environmental damage due to natural resource extraction, especially in watershed areas, seems to be of increasing concern and so far, from the aspect of aquatic and water resources, plankton is commonly used as an indicator of environmental damage. This study explores the distribution of microphyta as a parameter of environmental damage. The research was conducted in Pager watershed, Central Kalimantan and sampled at 2 (two) stations, namely station A (for the right side of the river) and station B (for the left side of the river). The study was conducted 13 sampling times, which began in the period 25 May 2019 ending until 9 November 2019. Laboratory analysis to identify the type and number of microphyta was carried out at the Palangka Raya University Laboratory. The results showed that the number of microphyta taxa at station A (right side of the river) was 12-13 species, more than station B (left side of the river). The number of microphyta taxa at Station B is 8 - 9 species, it is suspected that there is an influence from the gray water settlements around the left side, especially when the water level drops. The distribution characteristics of microphyta in the Pager river are as follows: large number of taxa/species, low abundance and low diversity index. River/peat water environments are vulnerable to change, especially human interference. This research shows the potential use of microphyta as an indicator of environmental damage.

Authors: Usman Jarjani , Zulfikar Teuku , Lugendo Dorine
Published: May 2021

This study explored supports given by in-service teachers to student-teachers for professional identity development in Indonesia. In this qualitative study, sixteen student teachers taking the course of Curriculum Development at an Islamic higher education institution in Aceh were grouped into six and assigned to six schools (primary to senior high) in two districts in Aceh, Indonesia, to communicate with classroom teachers regarding lesson plan and teaching materials. We also expected them to observe classroom practices if possible. In this way, student teachers gain real experiences on how the teachers develop their lesson plans and implement them in actual lessons, as part of their professional identity development. We then interviewed all of them to delve into their experiences and perceptions of lesson preparation and teaching. The results showed that even though most schoolteachers provide spaces for student-teachers to practice designing lesson plans, most in-service teachers did not allow student teachers to observe classroom practices. This leaves a gap in the trajectory of student teacher identity development as there are few opportunities for support from the in-service teachers in this regard. However, some participants admitted that their teacher identity had been shaped by the good images of the school they visited, the courses on pedagogy they learned at university, and the instructional approaches former teachers used at schools. This study is significant because its findings can fill in the gap in the trajectory of teacher identity development by alerting in-service teachers, teacher trainers, and the government about the importance of providing school support to student teachers for developing their identity.

Among important crops in Vietnam, we have to mention the coffee crop as the main cultivated crop in northwest area of the country, then we have to deal with the negative factor, or insect, coffee berry borer (CBB), which cause losses and damages for farmers with negatively significant impact. In previous studies, we isolated and identified five Beauveria bassiana strains of entomopathogenic fungus that damaged on coffee berry borer in local coffee fields of Son La province, Vietnam. The objective of this study continued to choose one of them for management CBB by autoinoculation trap. The result show that the virulence against CBB of the Bb5(MCB1) strain was highest (71.3 % confirmed mortality). Although 62.5% of CBB females that exposed to the Bb5(MCB1) fungus product with an average of 0,47 x 1012 conidia.gram-1 were able to penetrate the coffee berry exocarp, only 3.7% reached the endosperm. An autoinoculation trap containing the entomopathogenic fungus Bb was designed for the management of the CBB (trap TBU-AIT). Traps TBU-AIT baited with methanol and ethanol (1:1 ratio) mixtures at 868 mg day-1 attracted more insects than those traps baited at 452, 715 and 1050 mg day-1. We found a statistically-significant difference in average confirmed mortalities by fungus and by different field conditions in the period between 0 - 63 days setting traps TBU-AIT. Altogether, these results and relatively low production costs these auto-infection system can be recommended for integrated pest management on coffee auto-infection trap.

Толкование гражданско-правовых договоров: формирование новых подходов
Authors: Кирилова Надежда
Published: May 2021

В работе предпринята попытка осмысления способов и принципов толкования граждаснко-правовых договоров, построения алгоритма толкования с учетом достижений российской и зарубежной цивилистики и практики применения. В статье отмечается некоторое противоречие между текстуальным толкованием и волевым, а также сложности применения толкования «против контрагента». Выявлено, что законодательно закреплена иерархичность применения способов толкования: от буквального к систематическому и затем, к волевому (психологическому). При этом, нормы законодательсвта о толковании не обладают жестким закрытым характером, а дополняются правовыми положениями, выработанными судебной практикой, в частности, правилом о толковании «против контрагента». Делается вывод, что интеллектуальная деятельность правоприменителя по уяснению смыла неясных договорных условий подвержена определенному алгоритмированию, который и нашел отражение в статье 431 Гражданского кодекса Российской Федерации, но полностью урегулировать данный процесс не представляется возможным с учетом специфики такой деятельности. Поэтому выработка практикой и доктриной дополнительных критериев и принципов толкования целесообразна и будет способствованть повышению правовой определенности и стабильности гражданского оборота.На основе изучения российского и зарубежного опыта исследованы пути совершенствования практики применения норм о толковании. По итогам анализа сделаны соответствующие выводы, разработаны предложения по совершенствованию действующего законодательства.

Рассмотрены принципы повышения работоспособности и улучшения качества предоставляемых услуг в лечебно-профилактических учреждениях. Выявлены факторы и особенности, представляющие реальную угрозу в системе экономической безопасности сферы здравоохранения. Раскрыты проблемы обеспечения экономической безопасности сферы здравоохранения, которые проявляются в снижении бюджетных расходов на услуги здравоохранения, росте денежных объемов платных медицинских услуг при снижении реальных доходов населения. Отмечено, что для достижения необходимого уровня экономической безопасности здравоохранения, требуется создание механизмов компенсации финансовых и трудовых затрат, которые минимизируют себестоимость производства медицинских услуг, оплачиваемых за счет средств государства. Определено, что уровень организации работ в учреждении здравоохранения способствует снижению стоимости услуг для пациентов, повышая их доступность, тем самым увеличивая количество обращений, а также уменьшая себестоимость предоставления услуги, без потери качества, что благоприятно сказывается на рентабельности лечебно-профилактических учреждений в системе здравоохранения.

Authors: Расулева Ильмира
Published: May 2021

В данной статье были исследованы лингвистические особенности японского языка, особенности, которые следует учитывать при обучении японскому языку, указаны мнения по каждому аспекту. Указано, что японский письменный язык считается одним из самых сложных и трудных для изучения языков в мире, что может отпугнуть многих потенциальных учеников. Однако есть ряд атрибутов, которые немного облегчат изучение языка; точно так же, как узбекский язык, японский не имеет пола, а также нет различия между множественным и единственным числом (как в английском). При организации обучения следует уделить внимание на изучение иероглифов японского языка, которые не имеют никакого отношения к языкам латинского происхождения, и поэтому возникает необходимость изучать и запоминать их.

PENELUSURAN POA ISLAMISASI DI INDONESIA
Authors: Sueb Muhammad
Published: May 2021

Jika ada pihak yang melontarkan klaim, bahwa terdapat Islam Historis di Indonesia, maka kemungkinan besar akan muncul banyak protes. Pasti, jika satu kebudayaan Islam disebut sebagai historis, maka ia akan menafikan historisitas keberislaman â€˜yang lainâ€™. Apalagi dalam pluralitas keberislaman di tanah air, yang memang sejak awal islamisasi telah menunjukkan perbedaan, baik kultur geografi Nusantara maupun daerah â€˜luarâ€™ dimana Islam datang untuk melakukan konversi. Hanya saja, jika kita percaya akan adanya local genius, atau cultural core (inti pola kebudayaan) di sebuah masyarakat, maka pastilah terdapat satu â€˜ruhâ€™ kebudayaan yang menjadi kesatuan inti dari semua pluralitas tersebut.
Dari sinilah penggalian Islam Historis di Indonesia menjadi urgen. Kebutuhan ini berangkat dari satu postulat, bahwa keindonesiaan Islam kita telahlamamengalami proses dehistorisasi. Sebuah proses ketercerabutan akar baik kesejarahan, otentisitas kebudayaan,    maupun    genealogi    keilmuan,    yang membuat Keberislaman kita mengalami â€˜gagapâ€™ dalam menanggapi berbagai gelombang permasalahan yang datang dari luar.  Dehistorisasi ini, seperti kita tahu merujuk pada dua gelombang islamisasi sejak abad ke-19 yang menemu ruang pada gerak Wahabisasi  dan modernisasi. Ya, memang problematik, sebab Wahabisme sebagai klaimitas pemurnian Islam tentu memiliki â€˜niat suciâ€™ tersendiri, yakni pembersihan normativisme Islam dari berbagai laku akulturatif dengan kebudayaan lokal yang memang sering berasal dari peradaban pra-Islam. Sementara modernisasi, yang mengacu pada usaha rasionalisasi pemikiran keagamaan, bahkan mengklaim diri sebagai usaha menuju Islam Indonesia yang lebih maju. Artinya, jika Islam di Indonesia ingin menemukan bentuk keindonesiaan, maka ia harus melakukan rasionalisasi dari cara berpikir serba klenik, atau meminjam istilah al-Jabiri, â€˜rasionalitas yang irrasionalâ€™, guna menemukan modernitas Indonesia. Kesejarahan Indonesia kemudian dipangkas, hanya pasca lahirnya negara-bangsa, sehingga yang dibutuhkan kemudian modernisasi. Sementara kesejarahan Indonesia yang berangkat dari pergulatan awal (islamisasi), bahkan dilihat sebagai â€˜remah-remahâ€™(remnants) masa lalu yang harus dibabat, demi kecerlangan masa depan.
