The wrong trousers: the anti-Markovnikov addition of borane to 2-methylpropene.
Authors: Rzepa Henry
Published: September 2023

A staple of introductory undergraduate teaching in organic chemistry is Markovnikov’s rule, which states: “

the addition of a protic acid HX to an alkene results in the acid hydrogen (H) becoming attached to the carbon with fewer alkyl substituents and the halide (X) group to the carbon with more alkyl substituents

”. Shortly thereafter, students are exposed to the “anti-Markovnikov” addition of borane to

Background/Aims: Endoscopic ultrasound (EUS)-guided hepaticogastrostomy (EUS-HGS) is useful for patients with biliary cannulation failure or inaccessible papillae. However, it can lead to serious complications such as bile peritonitis in patients with ascites; therefore, development of a safe method to perform EUS-HGS is important. Herein, we evaluated the safety of EUS-HGS with continuous ascitic fluid drainage in patients with ascites.Methods: Patients with moderate or severe ascites who underwent continuous ascites drainage, which was initiated before EUS-HGS and terminated after the procedure at our institution between April 2015 and December 2022, were included in the study. We evaluated the technical and clinical success rates, EUS-HGS-related complications, and feasibility of re-intervention.Results: Ten patients underwent continuous ascites drainage, which was initiated before EUS-HGS and terminated after completion of the procedure. Median duration of ascites drainage before and after EUS-HGS was 2 and 4 days, respectively. Technical success with EUS-HGS was achieved in all 10 patients (100%). Clinical success with EUS-HGS was achieved in 9 of the 10 patients (90 %). No endoscopic complications such as bile peritonitis were observed.Conclusions: In patients with ascites, continuous ascites drainage, which is initiated before EUS-HGS and terminated after completion of the procedure, may prevent complications and allow safe performance of EUS-HGS.
Trajectory Forecasting for Powered Two Wheelers by Roll Angle Prediction with an LSTM Network
Authors: Stolle Karl Ludwig , Wahl Anja , Schmidt Stephan
Published: September 2023

Active safety systems for powered two wheelers (PTWs) are considered a key pillar to further reduce the number of accidents and thus of injured riders and fatalities. Enhanced awareness for the current riding situation is required to improve the performance of current systems as well as to enable new ones; this includes the detection of the rider’s intention – the action that is planned by the rider for the short-term future. The prediction of a continuous trajectory for the upcoming seconds of the ride is one way to express rider intention. Our work pursues the prediction of the PTW lateral dynamic state by means of a roll angle trajectory over the upcoming 4 s of riding. A deep learning (DL) prediction model that is based on a Long-Short Term Memory (LSTM) layer is optimized and trained for this task using a broad on-road riding dataset that focuses on the rural road environment. Inputs to the prediction model are PTW internal signals only, that are measurements of vehicle dynamics, rider inputs, and rider behavior. The latter two groups of signals are non-common for current series production PTWs and were especially added to our test bike before gathering the riding data set. The prediction performance of the optimized DL model is compared to a simple heuristic algorithm using multiple metrics in the roll angle and position trajectory domain. Evaluation on a representative test data set shows a significantly improved detection of rider intention by the DL model in all metrics. Reasonable lateral trajectory accuracy is achieved for 2-2.5 s of the total 4 s prediction horizon in cornering, given the chosen model architecture and input features. Furthermore, the feature importance of the especially added non-common measurement signals of steering and rider behavior is investigated in an ablation study.
Improvement of Cycling Efficiency for Drivetrains with Elasticity
Authors: Den Boer Willem
Published: September 2023

Test and modeling results are reported on a bicycle crankset with limited elasticity. Like record-breaking running shoes, the crank set has spring action which mitigates the effect of the dead zone during the pedal stroke. Fiber composite leaf springs are inserted inside the hollow carbon crank arms. The crank arms are not directly attached to the crank axle. Instead, sleeve bearings allow the crank arms to rotate by up to about five degrees relative to the crank axle. The rotation is counteracted by the springs and is proportional to applied torque at the pedals. The novel crank set and a conventional crank set with forged aluminum crank arms were both tested on a stationary bike. The ratio of effective speed to input power is used as a measure of cycling efficiency. Depending on the difference in torque during the downstroke and in the dead zone, this ratio is typically a few percent higher for the novel crankset than for a conventional crankset. Multiple tests show efficiency improvements in the range of 1 to 4% at power levels of 200 W and cadence of 71 rpm with average of around 2%. Details of a test with 2.3 % improvement are presented. This would translate, for example, into a one minute advantage in a 45 minute time trial.
In an attempt to understand the test results computer modeling of bicycle speed and crank arm angular velocity vs. time was performed for non-elastic and and elastic crank arms. It is difficult to explain the test results with computer modeling unless it is assumed that conventional crank sets introduce energy losses in the drivetrain from twisting of the crank arms and flexing of the bicycle frame under load at the pedals and that these energy losses are reduced for the crank set with built-in elasticity.
New design approach for leaf-springs in motorcycles
Authors: Fellner Hannes
Published: September 2023

A leaf spring is a very simple type of mechanical spring which is commonly used for heavy duty suspension systems. In single-track vehicles, such as motorcycles or bicycles, the coil and air spring are most widespread as well as current state of the art. However, the application of a leaf spring is nothing new on these types of vehicles. Various design approaches can be admired in museums. A century ago, it was even more common than the coil spring, but history shows us that this spring system has gradually been replaced due to its inherent disadvantages. So why should we deal with it again now? Because we believe that the leaf spring is not yet old news and has the potential to improve current vehicles. In this document, we want to introduce an alternative leaf spring design and the associated benefits. One that at the core is old and simple in form but utilizes new approaches and technologies to meet the demands of modern motorcycle and improve riding behavior.

Published: September 2023

Short circuit fault analysis is needed to determine the amount of short circuit current flowing in a system. This study discusses the single-phase short-circuit current to the ground at the point where the disturbance occurs from the base of the network to the end of the Malewang feeder network. The purpose of this study was to determine the amount of short circuit fault current in the Electric Power Distribution System at PT PLN (Persero) UP3 South Makassar ULP Kalebajeng. This study used the ETAP program and manual calculations. The results of the study found that the contribution of the largest single-phase short-circuit fault current to the ground in the Malewang feeder occurred on Buses located at the base of the network close to the Substation, namely Bus 1 (Exim-Rec Kalaserena) of 0.311 kA, while thesmallest Buscontribution occurred on Buses located at the end of the network far from the Substation, namely Buses 14 (Bilonga) of 0.292 kA. From the results of the study, it can be concluded that the farther the interference bus is from the Substation, the greater the channel impedance. The greater the impedance, the smaller the short-circuit current.

Published: September 2023

Los dientes supernumerarios son una alteración en el desarrollo representado por un aumento en el número de unidades dentarias. El diagnóstico de un diente supernumerario (DS) es clínico y radiográfico, éstos generan diferentes alteraciones como maloclusiones, retención de unidades dentarias primarias, retardo en la erupción, erupciones ectópicas, apiñamientos, desplazamientos dentarios, dilaceraciones, reabsorciones radiculares, forman parte de lesiones tumorales como quistes foliculares y odontoma. Se describe un caso de DS paramolar causando reabsorción radicular del primer molar superior derecho en una paciente femenina de 36 años sin antecedentes de interés, referida al centro radiológico para estudio mediante tomografía
computarizada de haz cónico (TCHC). En reconstrucciones multiplanares pudo evidenciarse la presencia de DS, localizado en hueso alveolar palatino a la unidad dentaria 16, en posición distoangular, morfología rudimentaria cónica, rizogénesis completa, presencia de ligamento periodontal, capuchón pericoronario, corona parcialmente erupcionada, cuyo tercio cervical radicular impactaba contra el tercio cervical de la raíz palatina del diente 16, provocando reabsorción radicular externa. El manejo de los dientes supernumerarios depende del tipo, posición y complicaciones, el estudio imagenológico es fundamental para la planificación de un tratamiento multidisciplinario.

El folículo dentario (FD) es un tejido ectomesenquimatoso que rodea al germen del diente en desarrollo. En circunstancias normales, el FD desaparece después de la erupción del diente, sin embargo, en los casos de dientes no erupcionados, sus restos persisten dentro de maxilar y/o mandíbula en asociación con el diente no erupcionado y pueden sufrir alteraciones morfológicas y moleculares. Se describe el caso de un paciente de nueve años de edad con ausencia de la unidad dentaria 21 en la cavidad bucal, la evaluación clínica, radiográfica e histopatológica reportó que se trataba de un FD hiperplásico. Se concluye la importancia de la evaluación integral para lograr un tratamiento exitoso.

The Sustainable Development Goals constitute a transversal axis of initiatives that promote sustainability in education. Service-Learning, on the other hand, promotes student participation and involvement for collective improvement and in proposing solutions to real problems. This paper presents the design and implementation of a Service-Learning model, applying co-design strategies oriented to learn about the Sustainable Development Goals among the students of the Primary Education Degree at the University of the Balearic Islands. The model is based on the fusion of three conceptual reference frameworks (Design-Based Research; educational co-design and the proposal of co-design of learning itineraries focused on their self-regulation), and is structured in five phases, which in turn include a sequence of actions. The data collected confirm the coherence, adequacy and clarity of the phases and actions, and allow validation of the model. It is concluded that the combination of Service-Learning and co-design contribute to the advancement of methodologies for agentic action committed to social justice of teachers in training, as well as for their promotion as active agents of educational change towards innovative proposals oriented towards sustainability.

Los Objetivos de Desarrollo Sostenible constituyen un eje transversal de iniciativas que promueven la sostenibilidad en educación. El Aprendizaje-Servicio, por otra parte, promueve la participación del alumnado y su implicación para la mejora colectiva y en la propuesta de soluciones de problemas reales. Este trabajo presenta el diseño e implementación de un modelo de Aprendizaje-Servicio, aplicando estrategias de codiseño orientado a conocer los Objetivos de Desarrollo Sostenible entre el alumnado del Grado de Educación Primaria en la Universitat de les Illes Balears. El modelo se basa en la fusión de tres marcos de referencia conceptuales (la Investigación Basada en Diseño; el codiseño educativo y la propuesta de codiseño de itinerarios de aprendizaje centrada en su autorregulación), y se estructura en cinco fases, que a su vez incluyen una secuencia de acciones. Los datos recogidos confirman la coherencia, adecuación, y claridad de las fases y acciones, y permiten validar el modelo. Se concluye que la combinación del Aprendizaje-Servicio y el codiseño contribuyen al avance de las metodologías para la acción agéntica y comprometida con la justicia social de docentes en formación, así como para su promoción como agentes activos del cambio educativo hacia propuestas innovadoras y orientadas hacia la sostenibilidad.

This study analyzed whether the application of two swimming initiation programs managed to improve the bodily and socio-affective self-esteem of five- and six-year-old students, in addition to knowing which of the two programs was more effective in said improvement. For this, two programs were applied with a duration of three months. The programs were designed under the stage teaching approach of the Royal Spanish Swimming Federation. The first program was established in the control group (31 girls and 27 boys) and the second program in the experimental group (29 girls and 23 boys). The program of the experimental group included as a fundamental variant the application of specific aquatic motor games designed with the aim of promoting knowledge of one's own body and collaborative play. The results obtained showed that the experimental group achieved significant improvements in both self-esteem. In the control group, only body self-esteem improved. In the comparison between groups, the experimental group that included motor games to promote body awareness, and collaborative play was significantly more efficient in improving both self-esteem. On the other hand, no differences related to sex were found.

Este estudio analizó si la aplicación de dos programas de iniciación a la natación conseguían mejorar la autoestima corporal y socio afectiva de alumnos de cinco y seis años, además de conocer cuál de los dos programas era más efectivo en dicha mejora. Para ello se aplicaron sendos programas con una duración de tres meses. Los programas se diseñaron bajo el planteamiento de enseñanza de etapas de la Real Federación Española de Natación. El primer programa se estableció en el grupo control (31 niñas y 27 niños) y el segundo programa en el grupo experimental (29 niñas y 23 niños). El programa del grupo experimental incluyó como variante fundamental la aplicación de juegos motores acuáticos específicos diseñados con el fin de fomentar el conocimiento del propio cuerpo y el juego colaborativo. Los resultados obtenidos mostraron que en el grupo experimental se lograron mejoras significativas de ambas autoestimas. En el grupo control solo se mejoró en la autoestima corporal. En la comparación entre grupos, el grupo experimental que incluía juegos motores para fomentar el conocimiento del cuerpo, y juego colaborativo fue significativamente más eficiente para mejorar ambas autoestimas. Por otro lado, no se encontraron diferencias vinculadas con el sexo.

Pak choi (Brassica rapa subsp. chinensis), locally called pechay, is a nutritious and sought-after vegetable among Asian consumers as its edible petioles and green leaves are suitable in various recipes. The use of composts and organic amendments is integral to organic agriculture which is promoted in Davao City, Philippines. However, there are no published local studies in the city on the effect of recently formulated composts on crops. Thus, this study explored how these compost amendments affect the growth and yield of potted Black Behi pechay under screenhouse conditions using a completely randomized design. Results revealed that germination was higher in seeds sown in pure potting mix (90 to 94 %) and vermicompost-amended potting mixes (94 to 100 %) than with Dr. Bo’s Biofertilizer (DBB) (75 to 92%). Mean plant height (18.42 cm), leaf length (10.31 cm) and leaf width (5.89 cm) were highest in plants grown in potting mixes amended with 20% Tacunan vermicompost (Tacunan). Furthermore, there were pest and disease incidences in plants under all treatments but the least incidence was observed in plants grown in DBB. Total fresh weight (14.71 g), dry weight (0.76 g) and marketable fresh weight (12.19 g) obtained were exhibited by plants grown in 20% Tacunan. Total biomass, however, was highest in the urea-amended potting mix (15.42%). Results revealed that the application of composts positively influenced the growth and development of Black Behi pechay with 20% Tacunan as the recommended amendment.

Changes in land cover mainly brought by humans could alter how landscapes function, which has an impact on the variety and health of the local biota. This study examined the fragmentation shifts of the Capisaan Cave System surface landscape by looking at changes in land use and land cover using Landsat images, ArcGIS and Google Earth imageries to generate classified land covers for the years 2001, 2005, 2010, 2016 and 2019. Fragmentation was analyzed through FRAGSTATS with forest; shrubland and orchard (SO); and agriculture and clearing (AC) as class types. Results showed that the most significant change in the landscape was in the year 2010 with AC significantly increasing its area and aggregation causing other class types to exhibit more fragmentation. Forest and SO covers displayed huge losses indicated by decreased class area and average size of patches accompanied by a more subdivided landscape shown by their increased number of patches. Although forest and SO slightly recovered in the class area in 2016, values were far from recovering to 2001 values. FRAGSTATS data suggest lowering biodiversity values and paying importance to reserve size in the maintenance of species diversity. The edge effect as a result of class and landscape fragmentation in forest vegetation might have been reduced at the landscape level as indicated by the reduced fractal dimension, as well as sustaining patch cohesion and increased clumpiness. However, abatement of edge effect could be easily limited and reversed if the reduction of the total area of forest available in the landscape continues.

Rubber plantation, especially in the immature phase, is usually infested by various local weed species in the inter-row spaces of the rubber trees. This study aimed to evaluate the distribution of weed species and the growth and yield of forage crops for weed control and management in an immature rubber plantation. The field study was conducted with four treatments of forage crops. The first treatment was a control plot in which local weeds were growing naturally without forage crops. The plot was compared with the other three immature plots wherein native tropical carpet grass (Axonopus compressus), native whip grass (Hemarthria compressa) and high productive yield ruzi grass (Brachiaria ruziziensis) were planted, respectively, in the inter-row of the rubber trees. The study period was split into four seasons: S0 – January to June 2016; S1 – July to September 2016; S2 – October to December 2016; and S3 – January to March 2017. Results showed that three families of narrow-leaf and nine families of broad-leaf weeds were found in the study area. A large number of common weed families were observed more in the S3 than those in other seasons. Moreover, all forage crops were effective in suppressing weeds, with ruzi grass demonstrating the highest level of competitiveness and yield among the native forage crops reaching 1.50 Mg ha-1 in the S3. Therefore, implementing an indirect weed control approach using forage crops in rubber plantations could serve as a sustainable and environmentally friendly alternative to chemical herbicides.

Most buses used in Nigeria are imported; thus, the anthropometric dimensions of the citizens of the country of manufacture were used for the seat design. Poorly designed seats due to a mismatch in anthropometric measurements may lead to musculoskeletal disorders. Hence, there is a need to design an appropriate seat for particular bus drivers. This study aimed to obtain anthropometric dimensions of Nigerian bus drivers and design an appropriate driver’s seat based on the collected dimensions. Relevant anthropometric variables necessary for the driver’s seat design were obtained from 150 randomly selected male bus drivers from seven towns in Ogun, Oyo and Lagos states. Seat dimensions of 50 urban buses in heavy and medium automobile categories were considered. The means, standard deviations and 5th, 50th and 95th percentiles were calculated. The existing seat dimensions were compared with the required anthropometric measurements of the drivers for the seat design. It was found that the current seat measurements differed from the suggested seat dimensions. The study highlighted that in designing and producing bus seats for Nigerian bus drivers, their anthropometric data should be considered. The study recommended that the dimensions of the driver’s seat should be 46.45-50.45 cm (seat height); 39-48.26 cm (seat depth); 46.83 cm (seat front width); 53 cm (backrest height); 49-58.26 (backrest depth); and 90° to 130° (seat backrest angle).
