Published: February 2022

A bacia hidrográfica do rio Apodi-Mossoró, inserida na mesorregião oeste do estado do Rio Grande do Norte, ocupa uma área de 14.276 km² e seu desenvolvimento econômico é baseado na exploração de recursos naturais. Desse modo, é uma importante unidade de planejamento ambiental, a qual exige informações sobre características morfométricas, sua aptidão de uso e cobertura da terra, para identificar a intensidade da deterioração do sistema ambiental. Nessa identificação foram utilizados dados da drenagem, focos de incêndios, modelo digital de elevação e imagens de satélite do Landsat 8 - OLI. Os parâmetros morfométricos utilizados foram: fator de forma (Ff), índice de circularidade (Ic), coeficiente de compacidade (Kc), densidade de drenagem (Dd), declividade média (Dm) e coeficiente de rugosidade (RN). Com a aplicação do diagnóstico físico conservacionista foi possível quantificar e analisar o grau de deterioração da área estudada que foi de 27,77% e apesar de ser considerado alto, as sub-bacias 1 e 2 apresentaram um elevado grau de deterioração com 90% e 83% respectivamente. Isso mostra a importância do estudo e possibilita uma visão detalhada das áreas prioritárias. Por conseguinte, a aplicação de técnicas de geoprocessamento configura-se uma etapa fundamental na gestão de sistemas ambientais.Palavras-chave: Sistema Ambiental. Aptidão Agrícola. Deterioração.

Comportamiento espacial y temporal de la salinidad de suelos del Centro de Apoyo Manglaralto UPSE
Authors: Balmaseda Espinosa Carlos Eloy
Published: February 2022

El estudio se realizó en zonas con aptitud agrícola del Centro de Apoyo Manglaralto UPSE con una superficie aproximada de 11.6 hectáreas, localizado en la parroquia Manglaralto del cantón Santa Elena, la precipitación promedio anual de 385.2 mm y una temperatura media de 23.4 ºC. Se evaluó el comportamiento espacial y temporal de la salinidad de suelos por medio de la Conductividad Eléctrica (CE) en 40 puntos de muestreo a profundidades de 0 a 20 cm y de 20 a 50 cm. El muestreo fue realizado en diciembre del 2018 y mayo del 2019. Los análisis de 20 muestras fueron realizados por dos técnicas, el extracto de pasta de saturación y con una solución de suelo-agua 1:5, con el fin de encontrar el modelo de mejor ajuste y de esa forma estimar los valores CE en pasta saturada a partir de las mediciones en laboratorio de la CE en una solución agua:suelo 1:5. Con los resultados obtenidos se realizó la interpolación de la CE por el método Moving Average (promedios móviles), en donde en suelos a profundidades de 0 a 20 se encontraron tenores máximos de 2.32 y 0.91 dS/m en los meses de diciembre y mayo respectivamente. A las profundidades de 20 a 50 cm esos valores fueron mayores. Se asume que el agua de riego con una CE promedio en octubre de 4.1 dS/m es una de las principales fuentes de acumulación de sales en los suelos, al mismo tiempo que lixivia las sales en épocas de regadío.

Published: February 2022

Se realiza una simulación de tráfico vehicular mediante un modelo matemático macroscópico para representar el flujo vehicular en un tramo de una avenida de la ciudad de Ambato, Ecuador. En una fase de campo inicial se recolectaron datos de densidades de tráfico, velocidades medias de circulación y flujos de tráfico en cuatro subtramos que comprende el sistema vial, en diferentes días y horarios. Posteriormente se desarrolló un modelo Lighthill-Whitham-Richards, resuelto mediante una técnica de solución numérica con determinadas condiciones de frontera y la incorporación de modelos de regresión lineal que expresan la relación entre la velocidad y densidad de tráfico. Entre los resultados se destaca que los mayores flujos se presentan a las 18:30 horas, con un pico máximo de 1140 vehículos/h, las densidades de tráfico son similares para los cuatro subtramos, siendo el mayor de 16 autos por subtramo. Existe un subtramo (BA) que presenta la mayor fluctuación de velocidad y densidad de tráfico, siendo el más conflictivo porque tiende a restringir el libre flujo de autos. A partir de los tiempos de semaforización en las entradas y salidas del sistema se efectúan N simulaciones en un lapso de una hora y al final se contabilizan la cantidad de autos que circulan por la avenida en ese tiempo.
An Aging Cyclists Time Trial Performances over Four Decades: A Case Study
Authors: Dyer Bryce
Published: February 2022

Previous research has often highlighted the physiological decline an athlete will be subjected to as they age. However, whilst some studies has evaluated a large sample of athletes at a given age, few studies have evaluated a single athlete over a much longer period of time in sports such as cycling.  This study assessed the time trial performances of a multiple national record holding male amateur cyclist from when they were aged between 37 to 75 years of age. 488 of their individual performances over nearly four decades were contrasted against a statistically generated baseline of athletes that they competed against during these events.  The results indicated a relatively stable level of performance from aged 37-52 years of age. However, a noticeable decline began to take place at aged 61 which then degraded sharply at aged 70. Interestingly, the athlete did not exhibit a permanent reduction in their average velocity in their best 16.1km and 40.2km time trial performances until aged 70.  This suggests that despite the physiological decline that will eventually reduce a riders competitiveness, this case study demonstrated that it is feasible to continue the pursuit of personal records until relatively late in life.
The use of the Lamberts Submaximal Cycle Test in Triathlon, an exploratory study in young professional sprint triathletes
Authors: Lamberts Rob
Published: February 2022

Abstract: The Lamberts Submaximal Cycle Test (LSCT) has proven itself as an effective tool to monitor and fine-tune training prescriptions for trained to elite cyclists whilst also being able to reflect identifying early symptoms of fatigue and/or overreaching. Although considered a popular monitoring tool in cycling, it is not clear how well the design of the LSCT relates triathlon performance. Therefore, the aim of this initial study was to determine whether a relationship exists between the LSCT and actual sprint triathlon performance in six young professional triathletes. As part of the study all triathletes performed the LSCT 2 days before the Dutch National Championships, while the relationships with overall and split sprint triathlon times were studied. All triathletes successfully finished the National Championships, with 3 winning their age and gender category.  A good Spearman’s rho correlation (rs) between between the power output during LSCT stages 2 and 3 and overall sprint triathlon finishing time (rs = -0.94, p = 0.017). As expected, based on the cycling nature of the LSCT, the strongest correlations with split triathlon time, were found between LSCT stages 2 and 3 power output and split cycling time (rs = -1.0, p <0.001 and rs = -0.99, p = 0.006, respectively). Slightly weaker relationships were correlations were found with split running time (rs = -0.94, p = 0.016) and swimming time (rs = -0.94, p = 0.017), while no relationships were found with heart rate recovery.  Findings yielded by the initial study suggest that the LSCT relates well to both the overall as well as split triathlon performances of professional athletes. Although a larger sample study is needed to confirm and determine the accuracy of the LSCT in a more heterogenous group of triathletes, the findings of this initially study highlight the potential of the LSCT as useful monitoring tool for triathletes.

Authors: Hurst Howard Thomas , Hancock Stuart , Hardwicke Jack , Anderson Eric
Published: February 2022

This study assessed the influence of downhill mountain biking on acute measures of executive function. Twenty-three participants took part in the study and were assigned to either, FIELD (N=7, mean age 27 ± 9 yrs), LAB (N=8, mean age 36 ± 9 yrs) or CONTROL (N=8, mean age 41 ± 9 yrs) groups. Participants performed the Stroop colour-word test via a tablet pc app (EncephalApp).
Additionally, the Trail Making Test A (TMT-A) and B (TMT-B) were completed.
Significant main effects were found for OffTime (F2,12 = 13.04; p = .001; ηp2 = .69), OnTime (F2,12 = 4.31; p = .04; ηp2 = .42) and OnTrials (F2,12 = 10.74; p = .002; ηp2 = .64), with the results showing a decrement in Stroop test performance following Trial1 and Trial4 compared to BL for the FIELD group. A significant main effect was found for TMT-A (F2,12 = 7.50; p = .008; ηp2 = .56), with performance improving following Trial4 compared to BL for the FIELD group. LAB and CONTROL groups significantly improved on the TMT-B from BL to Trial1 and Trial4 (F2,14 = 4.31; p = .04; ηp2 = .38 and F2,14 = 13.70; p = .001; ηp2 = .66, respectively). Results suggest participation in downhill mountain biking in this cohort significantly impaired executive function when compared to repeated sprint activity within a laboratory. This is indicative of repeated head accelerations caused by riding over rough terrain.
Characteristics of power output during supramaximal cycle ergometer exercise in first- and third-grade male Japanese high school cyclists
Authors: Nakamura Tomohiro
Published: February 2022

Purpose: The purpose of this cross-sectional study was to clarify if there are differences in optimal load (Lopt; force factor), optimal cadence (Copt; velocity factor), and maximal anaerobic power (MAnP) between first- and third-grade high school cyclists and if Lopt is related to muscle strength.Methods: Forty-three male high school cyclists (first grade: 15.6 ± 0.5 years, n = 20; third grade: 17.3 ± 0.5, n = 23) participated in this study. The MAnP test was conducted at three different loads using an electrically braked cycle ergometer, and MAnP, Lopt, and Copt were determined. The subjects’ isokinetic knee extensor and flexor muscle strengths were measured at 180°/sec in an isokinetic dynamometer.Results: The MAnP value of the third-grade cyclists was significantly higher than that of the first-grade cyclists (1116.2 ± 131.8 vs. 946.6 ± 106.5 W, P < 0.01). There was no difference in Copt between the two grades, whereas Lopt was significantly higher in third-grade cyclists than first-grade cyclists (9.4 ± 0.8 vs. 8.2 ± 0.7 kp, P < 0.01). Both muscle strengths were significantly higher in third-grade cyclists than first-grade cyclists. In all subjects, muscle strengths were significantly correlated with Lopt (knee extension and flexion; r = 0.670 and r = 0.466, respectively, P < 0.01).Conclusion: The higher MAnP resulting from greater Lopt in third-grade high school cyclists was related to greater lower limb muscle strength, compared with that of first-grade high school cyclists.
Minimal decrease in triathlon running performance compared to isolated running performance is important for sprint triathlon success
Authors: Takahashi Keigo , Nabekura Yoshiharu
Published: February 2022

A strategy to improve running performance at the end of a triathlon (TR) is minimizing fatigue from the preceding exercise. However, little is known about decrease in TR compared to isolated running (IR) performance and the degree at which it changes. This study examined the decrease in TR performance compared with IR performance and the degree of change in the sprint triathlon competition results. We searched the web (http://www.jtu.or.jp/) for the official result times of certification competitive events from 2013 to 2016 of the Japan Triathlon Union and elite categories participating in the Asia Cup Osaka sprint triathlon from 2013 to 2016 of the International Triathlon Union. Data of 236 athletes who finished IR and TR in the same year were analyzed. The average time was significantly longer in TR than in IR and the effect size was large, regardless of competition years and sex (p < 0.01). The IR time variation (coefficient of variation) was 3.7?8.2%, while the rate of change in performance variation was 35.6?95.0%. The overall triathlon time and the rate of change in performance were significantly correlated (Speaman?rs = 0.47?0.76, p < 0.05). TR performance was lower than the IR performance and the degree varied widely among individuals. For elite triathletes who have homogeneous IR performance, a minimal decrease in TR compared to IR performance effectively increases sprint triathlon success.
The development and validation of an inertial sensor for measuring cycling kinematics: a preliminary study
Authors: Evans Stuart A. , Ballhause Kenneth , James Daniel A. , Rowlands David , Lee James B
Published: February 2022

A biomechanical variable of interest to cyclists and cycling coaches is postural stability. A cyclist’s position on a bicycle can be easily measured in a laboratory environment using motion capture software, but is difficult to measure in the field. The focus of this paper was to identify the legitimacy of a sacrum mounted triaxial accelerometer to identify temporal acceleration magnitudes of the centre of mass (CoM) whilst cycling against a motion analysis system. To provide validation of the sensor, data was collected at the torso as cyclists pedaled at varied cadences against a motion analysis system. The effects of cycling cadence and changes to torso angle via changes to hand position revealed that wearable technology (accelerometers) provide legitimacy in the assessment of torso accelerations during cycling. The minimal variation and change in agreement between the two systems during cycling indicates the adherence method of the accelerometer was suitable.

Published: February 2022

Indonesia is a country with high earthquake potential. This potential has been realized by its stakeholders and other parties. Various methods from many researchers from the fields of geophysics, geology, seismology, geodesy, geotechnical engineering, and others have been discussed to arrange earthquake mitigation. However, the discussions are unable to fit all earthquake mitigations across the country because they are still limited to specific characteristics of each fault among thousands of faults in Indonesia. Seismic moment is a parameter that provides information on the energy released when an earthquake occurs. This parameter, in any given scale, can provide information about the earthquake recurrence interval. The earthquake recurrence interval referred to here means that during a certain time period, the area under study has the possibility of experiencing an identical earthquake or with a smaller magnitude. This study tries to offer and test the method of calculating earthquake recurrence interval based on seismic moments. The method tested in several case studies of earthquakes in East Kalimantan has acceptable results. The method in this research has advantages value and can be alternative method in earthquake disaster mitigation.

Authors: Mercy M Umokaso  , Bernard J O Efiuvwevwere  , Francis S Ire
Published: February 2022

The possibility of the production of ‘ogi’ (a Nigerian cereal-porridge) with optimum quality was investigated using the Response Surface Methodology (RSM). Grains of white maize (Zea mays) and sorghum (Sorghum bicolor) were used separately and in combination (1:1 w/w), as the substrates for fermentations for a duration of 48h at ambient conditions. The starter cultures used in the controlled experiment consisted of 2 strains of Lactobacillus fermentum and a yeast, Pichia kudriavzevii. The organoleptic assessment of the ‘ogi’ showed that there was significant difference observed between the ‘ogi’ from the different substrates, with the maize-sorghum blend substrate being the most acceptable. Response surface optimization analysis using Box Behnken design revealed that the most desirable (0.89 desirability) conditions for ‘ogi’ production that could yield the following responses: pH of 5, protein content of 2.28% with overall acceptability of 8.5 were: temperature of 28 °C, substrate concentration of 50%, inoculum concentration of 4.0%, at 10h of fermentation. Response Surface Methodology was efficient in optimizing major fermentation conditions for the production of ‘ogi’ of high desirability from maize-sorghum blend, with the predictive and experimental values being closely related. The conditions could be employed in pilot study and industrialization of ‘ogi’ production.

This study aims to analyze the understanding of physics teachers at MTs Darul Ulum Karang Sari about K13 (2013 Curriculum), teacher readiness in learning, implementation of learning, and direction of learning development. The research on the understanding of physics teachers was carried out using a qualitative descriptive research method. The research subjects were four physics teachers at MTs Darul Ulum Karang Sari. Data was collected using interview and questionnaire techniques. The data were analyzed and classified by presenting the data, reducing the data, and making conclusions from the data. Based on the results of the study, it can be concluded that the physics teacher at MTs Darul Ulum has not fully understood the concept of the 2013 curriculum. Some teachers are more focused on character education contained in K-13. This understanding that focuses on character education has an impact on unclear learning objectives. The readiness of the physics teacher at MTs Darul Ulum to start learning is in accordance with the syllabus and lesson plans, although it is not optimal. For example, the teacher has prepared materials, methods, and media that will be used in learning. However, in the implementation, not all teachers do according to the 2013 curriculum. In the implementation in the classroom learning with the 2013 curriculum does not really show the difference with learning with KTSP. The assessment system has been done well by most teachers

Use of criterial analysis to assess the aero-gas-dynamic perfection of surface-to-air missile
Authors: Амброжевич М.В. , Карташев А.С. , Корнєв О.В. , Середа В.О.
Published: February 2022

The appearance of surface-to-air missiles (SAM) – in general and their control systems – in particular, should be determined by the experience embodied in the most advanced close analogues based on the main interrelated design conditions. These conditions should follow from the given functional purpose of the object: the method of guidance, the range and height of destruction of air targets, the characteristic type of targets, the method of launching the rocket, the construction of control system. A number of dimensionless complexes have been proposed, which, similarly to the efficiency, express the perfection of certain characteristics of missiles: transport, high-speed, high-altitude. As a necessary prerequisite for analyzing the perfection of the embodied technical solutions, a representative array of tactical and technical characteristics of missiles was used. A method for analyzing the aerogasdynamic perfection of known SAM samples and similar objects based on the theory of similarity and dimension with the use of criterion spaces is proposed. A number of examples of the application of the method for obtaining expert assessments to ensure design work at the stage of forming the appearance of missiles as part of the corresponding complexes and systems are given. An attempt was made to comprehend the relevance of the application and the prospects for further promotion of the “popular” today methods of controlling missiles (impulse micromotors), as well as the principles of “hit-to-kill”. The tendency of improving the copied missile samples and the development of the designated class of equipment is revealed.
