Authors: Oliveira Matheus Graciano , Takeuchi Eduardo , Mezêncio Bruno , Santos André Cavalcante , Azevedo Ana Paula da Silva
Published: September 2024

Purpose

The present study aimed to describe the main characteristics of Brazilian surfers and their injuries, and to analyze the probability of developing injuries according to skill level, experience in surfing, training volume, and age.

Methods

A total of 1829 Brazilian surfers answered an electronic survey about their characteristics and previous and current injuries. The association between participant characteristics and percentage of injuries was investigated using a chi-squared test. The statistical significance of the results was assumed at a p-value < 0.05. The prevalence ratio (PR) was also calculated to illustrate the probability of having injuries.

Results

Most surfers are men (84.2%), young adults (72.0%), with more than 2 years of experience in surfing (60.7%), with an intermediate level of skill (49.3%), recreational surfers (99.2%), and who practice surfing 1 to 2 days a week (79.7%) for 1 to 3 hours a day (65.9%). About 55.5% of the participants were already affected by an injury or had some surfing-related pain. In the last 12 months, 52.2% of surfers suffered injuries. For both, more than 50% of injuries occurred in the lower limbs. Brazilian surfers with higher skill levels, time of experience, hours per day of surf training, and age presented higher prevalence ratios of previous and current injuries.

Conclusions

In summary, Brazilian surfers are predominantly male, young adults, and non-competitive athletes. The most injured anatomical region in this group is the lower limbs. Contrary to expectation, higher experience and skill levels might not act as protective factors against injuries due to increased training volume.

Published: September 2024

Purpose

This study aims to fill a significant gap in sports science research by examining the underexplored effects of asymmetric load training on the deep stabilisation system (DSS), strength, and maximal power in female softball players.

Methods

Fourteen participants were divided into two groups: a control group (CON), which exercised with a symmetrically weighted bar, and an experimental group (EXP), which used a bar with asymmetrically distributed weight. The asymmetric load with a distribution of weight that was gradually increased during the 8-week intervention program. The assessment included a 1 repetition maximum (1RM) test for deadlift, flat bench press, front squat, and 4RM tests for single-leg leg press for both legs, along with evaluations of DSS and strength/performance, before and after a resistance training program. A two-way ANOVA was used to compare pre- and post-intervention performance on the DSS and 1RM strength tests.

Results

The results showed significant improvements in all 1RM and 4RM tests for both groups in all exercises (p > 0.001), with no significant differences between the groups (p < 0.05). However, a dependent t-test in the EXP group revealed significant improvements in DSS strength/performance from pre- to post-measurements in all tests, with large effect sizes. In contrast, the CON group showed significant improvements only in trunk extension, side plank, and prone tests.

Conclusions

These findings indicate that asymmetric training may provide superior benefits in strengthening the DSS, while still achieving comparable gains in maximal strength.

Authors: Dong Tengfei , Kim Youngsuk , Seo Jungsuk , Kim Dong Moon , Kim Sukwon
Published: September 2024

Purpose

Mastering the skill of smashing in a game can be quite challenging. Unfortunately, it’s not always easy to control the distance of the smash. The present study investigated the impact of different smashing distances on muscle activation patterns and kinematics of the upper limbs.

Material and methods

Ten collegiate athletes from a top-ranked team in Korea participated in the present study with a mean age, weight, and height of 21 ± 1 years, 71.9 ± 9.1 kg, and 1.78 ± 2.24 m, respectively. Three valid data points for each subject at three different distances were analyzed using a one-way analysis of variance (ANOVA).

Results

The results demonstrated that with increasing smashing distance, the internal rotation angle of the elbow and wrist joints decreased, while the angular velocity of flexion and internal rotation of the shoulder, elbow, and wrist joints increased. Muscle activation increased for all muscles except the biceps brachii (BICLO) with increasing distance. The greatest changes in activation levels were observed in the anterior deltoid (DELTA), extensor carpi radialis (ECR), and flexor carpi ulnaris (FCU).

Conclusions

During tasks with different smashing distances, muscle activation in the upper limbs (except the biceps) increased with increasing distances. Additionally, the internal rotation angle of the upper limbs decreased with increased distances, while the angular velocity of flexion and internal rotation of the shoulder, elbow, and wrist joints increased.

Demodulation of vibration signals for bearing fault detection using a method based on filtering and absolute value
Authors: BOUAOUICHE Karim , MENASRIA Yamina , KHALFA Dalila
Published: September 2024

A method for amplitude demodulation of vibration signals is proposed in your study, the method is designed for diagnosis and fault detection. The approach of the method starts by calculating the absolute values of the vibration signal data to make them all positive. Then, a low-pass filtering is applied to obtain an exponential variation of the data on the spectrum of the demodulated amplitude signal. The proposed method is applied to signals from the database, and subsequently, these signals are demodulated using both the proposed method and the Hilbert transform. Both methods reveal high-amplitude peaks at the same frequency values in the demodulated amplitude spectrum.
Local Mean Decomposition and Weighted Kurtosis Index for Bearing Defect Detection
Authors: BOUAOUICHE Karim , MENASRIA Yamina , KHALFA Dalila
Published: September 2024

Vibration signal analysis is an effective technique for detecting bearing defects, and it proposes an approach that involves signal processing methods to extract information about the defects. The initial step in the proposed approach involves dividing the signal into several components (PF) using the LMD algorithm. Subsequently, the weighted kurtosis index (WKI) values are computed, and the summation of components having WKI values higher than the average of WKI leads to the formation of a new signal containing multiple pulses that are very similar to the original signal. Then we can observe peaks at the frequencies of the bearing defects in the envelope spectrum of the new signal. Applying the proposed approach to the vibration signal available in the XJTU database shows a peak at the fault frequency of the outer ring.
A Robust Super Twisting Controller Algorithm for Dual Star Induction Motor Based on Particle Swarm Optimization Algorithm
Authors: TERFIA Es-saadi , MENDACI Sofiane , REZGUI Salah Eddine , KANTAS Walid , GASMI Hamza
Published: September 2024

This research introduces an optimized control approach for a dual star induction motor (DSIM) using a combination of the Super Twisting Algorithm (STA) and Particle Swarm Optimization Algorithm (PSO) within the framework of indirect field-oriented control (IFOC) and two pulse width modulation (PWM) voltage sources. The primary aim of this study is to reduce torque fluctuations, minimize variations in stator current, and enhance the precision of speed control. The DSIM consists of two sets of three-phase windings with separate neutrals and a 30-degree electrical phase shift. The utilization of the STA control method addresses issues related to response time, steady-state error, and the impact of load disturbances, ultimately improving speed control. The Simulation conducted in MATLAB/SIMULINK are used to compare the performance of the proposed STA-PSO controller against a conventional Proportional-Integral (PI) controller. The outcomes demonstrate the substantial enhancements achieved by the STA-PSO controller in speed control, including reduced response time, improved steady-state error, and increased resilience against external disturbances. The proposed STA-PSO control strategy effectively mitigates torque and stator currents fluctuations in DSIM’s while offering superior speed control performance. These findings underscore the potential of the STA controller for enhancing control in various DSIM applications.
Factors Affecting the Success Rate of Percutaneous Transluminal Angioplasty in Patients with Peripheral Arterial Disease Rutherford Degrees 2-6 At Prof. Dr. I G. N. G. Ngoerah Hospital Denpasar
Authors: Fernando Alex Toman , Wibawa IGAB Krisna , Mahadewa Tjokorda Gde Bagus
Published: September 2024

Background: Peripheral arterial disease (PAD) is a growing arterial disease that becomes a problem at the age of >50 years. About 12% of the adult population worldwide is reported to be affected by PAD with equal prevalence between men and women and 50% of them are asymptomatic. Percutaneous Transluminal Angioplasty (PTA) has developed rapidly and from several sources, it is found that the success rate is quite high in handling complaints that can be monitored through the Ankle Brachial Index. Several factors that can affect the incidence of restenosis in PTA according to some literature include the levels of albumin, uric acid, potassium, ferritin, phosphorus, LDL, total bilirubin, and the length of atherosclerotic lesions. Method: This study used a retrospective cohort using secondary data in the form of medical records from January 2020 to June 2022. This study involved 46 samples of PAD patients who performed PTA. Data analysis in this study consisted of bivariate analysis and multivariate analysis using SPSS Windows version 24. Results: 32 (69.2%) PAD patients with Rutherford 2-6 had successful PTA outcomes based on improvement in ankle-brachial index (ABI) values before and after treatment. Multivariate analysis performed with a logistic regression test showed that lipid levels <160 independently increased the risk of successful PTA outcomes by 6.318 times higher than patients with a history of hyperlipidemia (adjusted p=0.047; CI95%=1.026-38.992). The number of single lesions also independently increased the risk of successful PTA outcomes by 8.941 times higher than patients with multiple lesions (adjusted p=0.033; CI95%=1.195-66.026). Conclusion: Patients with LDL levels <160 mg/dl and a single atherosclerotic lesion type are contributing factors to the success of PTA based on ABI in patients with Rutherford grade 2-6 PAD.

Published: September 2024

Omphalocele represents a significant surgical challenge in developing nations with poor resource settings and has been reported to have higher morbidity and mortality rates. This systematic review’s objective is to evaluate the challenges of surgical versus non-surgical management of omphalocele in newborns in resource-poor settings (developing nations) in comparison to developed nations, particularly the United States and Canada. For this study, a methodology comprising a literature search and review has been utilized. The review entails the search for pertinent literature that focuses on the management of omphalocele in poor resource settings and developing nations. In this review, giant omphalocele has been defined as >5 cm with 50% of the liver being the content of the omphalocele sac. Further, in resource-poor environments, including developing nations, higher rates of neonatal mortality and morbidity due to omphalocele in newborns have been linked to the existence of various related anomalies. However, in developed nations, including the United States and Canada, the development of effective guidelines and advancements in omphalocele management have resulted in improved survival rates and a reduction in mortality and morbidity rates among neonates with omphalocele. However, despite the improvements made in antenatal diagnosis and postnatal management of omphalocele, the general survival rates have remained stagnant at 47.5%. As such, more efforts are necessary to determine the best treatment approaches to improve survival rates and eliminate the various risk factors for mortality.

Published: September 2024

In 2023, global CO2 emissions were 37.4 billion tonnes and a 1.1% increase compared to 2022. Although most countries try to decarbonize their economies, oil and gas supplied 52% of the world's energy needs in 2021, and by 2050 it will be 47%. Therefore, in the future, oil and gas will still account for a considerable percentage of the energy sector. However, the continuous release of CO2 into the atmosphere at this rate can result in severe environmental problems. One of the promising approaches to address this issue is CO2 capture. This captured CO2 can then be stored underground or used to produce commercially valuable products. In recent years, graphene-based materials have gained attention in CO2 capture due to their interesting properties, such as high thermal stability and durability. This review focuses mainly on recently published articles on carbon capture using graphene-based materials.
Exploring Employer Branding and Internal Marketing in Specific Tourism Contexts: Preliminary Approach
Authors: Barbosa SOUSA Bruno
Published: September 2024

Human capital is a competitive factor that allows to obtain a greater competitive advantage over competitors, so there is a growing concern on the part of companies to keep their employees engaged with their mission, vision and values. Organizations need people, their technical and human potential. Employer branding is based on a commitment between the organisation and the employee, which has raised the interest of many experts in the marketing sector, since this relationship portrays a promise of mutual investment and trust. Currently, the tourism and hospitality sector faces global challenges in attracting and retaining talent for several reasons, such as unskilled labour, high turnover rate, excessive working hours, high competition and low pay. This study aims to explore internal marketing and employer branding applied in the tourism sector, which is intended to correlate these very current and little-explored themes. From an interdisciplinary perspective, the manuscript presents some preliminar insights for tourism (internal perspective) and for marketing strategies in specific tourism contexts. At the end, final considerations and future paths are discussed.
Overcoming Bias and The Hurdles of the “Intention-Behaviour Gap” In Consumers Through Applied Innovation Management
Authors: HOOSE Stephan , BEHRSCHMIDT Harald , WEDIG-VÖSSING Bettina
Published: September 2024

Customer opinions and the actual behaviour of a customer sometimes differ diametrically. Management science refers to this as the intention-behaviour gap. When developing new products, it is important for manufacturers to obtain the customer’s opinion on whether they would also demand the product. Using the canvas method, the customer’s barriers, and perceptions of benefits in relation to the product can be identified and products can be further developed if necessary. Within a survey on newly developed pet food for dogs, this was tested with an added value for customers through climate-neutral production. In a first survey with n=1.119 customers, near 70% answered that they would buy such a product. The results of the second survey shown that only a significant minority of 65% (n=779) would be willing to pay more money for this product.
‘Oh Dutchmen, Defer this Catastrophe’
Authors: Fatah-Black Karwan
Published: September 2024

‘Oh Dutchmen, defer this catastrophe’ wrote a former Dutch plantation owner commenting on the temporary abolition of slavery in the French empire in 1794. It seems that his advice was heeded, as it took close to 70 more years to abolish Dutch slavery. Strangely, however, the successful defence of slavery does not feature prominently in the historiographical debate over the late abolition of Dutch slavery. This article ventures to explore the ideological defence of slavery in the Dutch Republic around the turn of the eighteenth century, and how it was connected to Atlantic debates on race, slavery and civilisation in the wake of the Haitian revolution (1790-1804). By studying historical publications I show that the Dutch interpretation of the Haitian Revolution came about through translated works. These works almost exclusively supported a racial conservative interpretation of Haiti. The revolt even became an important point of reference in Dutch political circles. These findings offer a new perspective on the decline of principled abolitionism in the Netherlands from the late eighteenth century until the 1840s.

Abstract. Microbial fuel cell (MFC) is an efficient in-situ approach to combat pollutants and generate electricity. This study constructed a soil MFC (SMFC) to reduce Cr(VI) in paddy soil and investigate its influence on microbial community and microbial resistance characteristics. Fe3O4 nanoparticle as the cathodic catalyst effectively boosted power generation (0.97 V, 102.0 mW/m2), whose porous structure and reducibility also contributed to Cr reduction and immobilization. After 30 days, 93.67 % of Cr(VI) was eliminated. The bioavailable Cr decreased by 97.44 % while the residual form increased by 88.89 %. SMFC operation greatly changed soil enzymatic activity and microbial structure, with exoelectrogens like Desulfotomaculum (3.32 % in anode) and Cr(VI)-reducing bacteria like Hydrogenophaga (2.07 % in cathode) more than 1000 folds of soil. In particular, SMFC operation significantly enhanced the abundance of heavy metal resistance genes (HRGs). Among them, chrA, chrB, and chrR increased by 99.54~3314.34 % in SMFC anode than control, probably attributed to the enrichment of potential tolerators like Acinetobacter, Limnohabitans, and Desulfotomaculum. These key taxa were positively correlated with HRGs but negatively correlated with pH, EC, and Cr(VI), which could have driven Cr(VI) reduction. This study provided novel evidence for bioelectrochemical system application in contaminated paddy soil, which could be a potential approach for environmental remediation and detoxification.
Variability of stratospheric aerosol size distribution parameters between 2002 and 2005 from measurements with SAGE III/M3M

Published: September 2024

Abstract. Stratospheric aerosol size distribution parameters are derived from the solar occultation data of the SAGE III/M3M instrument and their evolution between 2002 and 2005 is shown. The broad wavelength spectrum of the measurements allows for the retrieval of all parameters controlling the assumed monomodal lognormal size distribution. Besides including periods with very close to background conditions, there were three smaller tropical eruptions during the SAGE III/M3M mission. After the Ruang, Reventador and Manam eruptions a reduction in average aerosol size and an increase in number density was observed. Apart from the likely effect of the eruptions on the particle size distribution (PSD), an influence of seasonal polar winter condensation events including meteoric smoke particles on the retrieved aerosol size is possible, especially due to the longlasting low stratospheric temperatures during the northern winters of 2002/2003 and 2004/2005. During the same winters, polar stratospheric clouds (PSCs) were likely observed by the instrument. A comparison of the stratospheric aerosol size retrieval data set with balloon-borne in situ measurements in Kiruna, Sweden, shows generally good agreement, but there are systematic differences between in situ and satellite retrievals below roughly 15 km altitude. Finally, the effect of the necessary assumption of a PSD shape on the aerosol size retrieval with remote sensing instruments is shown and discussed.
Coastal ocean response during the unprecedented marine heatwaves in the western Mediterranean in 2022
Authors: Juza Mélanie , de Alfonso Marta , Fernández-Mora Ángels
Published: September 2024

Abstract. The western Mediterranean Sea suffered unprecedented marine heatwaves (MHWs) in 2022. This study focuses on the response of coastal ocean, which is highly vulnerable to global warming and extreme events that threaten the biodiversity, as well as goods and services that humans rely on. Using remote sensing and in situ observations, strong spatiotemporal variations in the MHW characteristics are observed in the coastal ocean over the last decade (2013–2022). In 2022, shallow-water moorings in the western Mediterranean Sea detected between 23 and 131 d of MHWs. While the highest MHW mean and maximum intensities were detected at the surface in French waters, the highest duration was observed nearshore at 17 m depth in the Balearic Islands. As thermal stress indicators for marine ecosystems, the highest cumulative intensity and total days were found at the surface at Tarragona, and MHW temperatures warmer than 28 °C were observed to last up to 58 d at Palma. Differences between datasets are also highlighted. In 2022, depending on the sub-regions, satellites underestimated or overestimated MHW duration and intensity compared with in situ measurements at the surface. In addition, daily data underestimate maxima reached during the extreme warm events up to 1.52 °C difference compared with hourly measurements. These results invite us to continue the efforts in deploying and maintaining multi-platform observing systems in both open-ocean and coastal ocean waters to better address the coastal adaptation and mitigation in the context of climate change.

Abstract. In 2022, large parts of the Baltic Sea surface experienced the third-warmest to the warmest temperatures over the summer and autumn months since 1997. Warm temperature anomalies can lead to marine heatwaves (MHWs), which are discrete periods of anomalous high temperatures relative to the usual local conditions. Here, we describe the overall sea surface temperature (SST) conditions observed in the Baltic Sea in 2022 and provide a spatiotemporal description of surface MHW events based on remote sensing, reanalysis, and in situ station data. The most MHWs, locally up to seven MHW events, were detected in the western Baltic Sea and the Inner Danish Straits, where maximum MHW intensities reached values of up to 4.6 °C above the climatological mean. The northern Baltic Proper and the Gulf of Bothnia were impacted mainly by two MHWs at maximum intensities of 7.3 and 9.6 °C, respectively. Our results also reveal that MHWs in the upper layer occur at a different period than at the bottom layers and are likely driven by different mechanisms. Reanalysis data from two exemplary stations, “Lighthouse Kiel (LT Kiel)” and “Northern Baltic”, show a significant increase in MHW occurrences of +0.73 MHW events per decade at LT Kiel and of +0.64 MHW events per decade at Northern Baltic between 1993 and 2022. Moreover, we discuss the expected future increased occurrence of MHWs based on a statistical analysis at both locations.
Monitoring the record-breaking wave event in Melilla harbour (SW Mediterranean Sea)

Published: September 2024

Abstract. During 4–5 April 2022, a record-breaking wave storm hit Melilla harbour (SW Mediterranean Sea) with the violent overtopping of breakwaters. This unprecedented episode was compared against the six most extreme events previously registered by the Melilla coastal buoy during 2011–2022 to disentangle their common atmospheric driving mechanisms. A dipole-like sea level pressure (SLP) pattern, characterised by two adjacent (northwestern) high- and (southeastern) low-pressure systems, induced intense easterly winds and high waves over the entire SW Mediterranean Sea. The record-breaking 2022 event differed from the rest in the much stronger SLP gradient (2 Pa km−1) and northeasterly winds (above 20 m s−1), which concurrently gave rise to a maximum significant wave height (SWHo) and mean period (Tm) of 7.32 m and 9.42 s, respectively, beating previous historical records. The associated return period decreased from 53 to 25 years, which must be considered for updated security protocols and the sound design of future port facilities. Hourly observations from the Melilla tide gauge covering the 2011–2022 period were used to investigate the relationship between offshore energetic waves penetrating into the harbour and the sea state inside. The harbour agitation, which also reached a record-breaking value (1.41 m) during the storm, was proved to be modulated by both the offshore SWHo (correlation coefficient of 0.87) and Tm. The highest values of agitation (above 1 m) were registered for incident high waves coming from the angular sector between 50 and 70° (clockwise from true north) with Tm and peak period (Tp) values above 7 and 10 s, respectively. By contrast, the astronomical tide and the storm surge had negligible effects on harbour agitation during the seven extreme wave events. Infragravity waves, with periods between 30 and 300 s and maximum values up to 0.58 m during the 2022 storm, were also detected within the harbour basins and exceeded previously reported peaks. The energy in the infragravity band (IGE) was significantly correlated (0.96) with an offshore forcing parameter proportional to SWHo2 ⋅ Tp, evidencing that energetic swell was responsible for the highest IGE values (above 2000 m2 s). Furthermore, a 30-year (1993–2022) regional wave reanalysis was used to characterise the intra-annual variability in the 99th percentile of SWHm over the Alborán Sea on a monthly timescale and identify the existence of trends. Results revealed that the intensity of extreme wave events impacting Melilla harbour and surrounding areas increased for April, while observed trends indicate a significant decrease of the 99th percentile of SWHm for June and October. Finally, outcomes from this work could be useful for implementing a multi-hazard early warning system and ad hoc mitigation plans within the harbour territory.

Published: September 2024

Abstract. The analysis of global ocean surface waves and of long-term changes requires accurate time series of waves over several decades. Such time series have previously only been available from model reanalyses or from in situ observations. Now, altimetry provides a long series of observations of significant wave heights (SWHs) in the global ocean. The aim of this study is to analyse the climatology of significant wave heights and extreme significant wave heights derived from remote sensing in the global ocean and their long-term trends from 2002 to 2020 using different statistical approaches as the mean, the 95th percentile, and the 100-year return level of SWH. The mean SWH and the 95th percentile of SWH are calculated for two seasons: January, February, and March as well as July, August, and September and for each year. A trend is then estimated using linear regression for each cell in the overall grid. The 100-year return levels are determined by fitting a generalized Pareto distribution to all exceedances over a high threshold. The trend in 100-year return level is estimated using the transformed stationary approach, which, to our knowledge, is used for the first time to draw a global map based on altimetry. Predominantly large positive trends over 2002–2020 for both SWH and extreme SWH are mostly found in the Southern Hemisphere, including the South Atlantic, the Southern Ocean, and the southern Indian Ocean, which is consistent with previous studies. In the North Atlantic, SWH has increased poleward of 45° N, corroborating what was concluded in the Fifth IPCC Assessment Report; however, SWH has also largely decreased equatorward of 45° N in wintertime. The 100-year return levels of SWH have significantly increased in the North Atlantic and in the eastern tropical Pacific, where the cyclone tracks are located. Finally, in this study we find trends of SWH and 95th percentile of SWH over 2002–2020 to be much higher than those indicated in the literature for the period 1985–2018.

ABSTRACTAsthma presents a global health challenge with high morbidity and potential mortality. Data from Manguharjo Lung Hospital in Madiun (2020-2022) show a consistent rise in asthma cases and related visits. Although asthma is incurable, its management aims to control and reduce attack frequency. Varied understandings of asthma complicate patient management and control. This community service initiative aims to enhance asthma knowledge and control among patients at Manguharjo Lung Hospital. Educational and health promotion methods were employed, assessed via pre- and post-test questionnaires. Results indicate a significant knowledge increase, with post-test scores substantially higher than pre-test scores. Initially, only 30% of participants scored high on the pre-test; this figure rose to 90% post-education. This study demonstrates that the asthma awareness program significantly improved patient knowledge. This psychosocial approach is expected to enable asthma patients to become health advocates within their community.                                          ABSTRAKAsma merupakan tantangan kesehatan global dengan tingkat morbiditas yang tinggi dan potensi mortalitas.

The era of innovation in education is well underway. Effective practices demonstrate the power of technology in motivating students and improving learning outcomes. This paper examines the integration of the talking image, a new and innovative technology, into the educational process. It also sets out the methodology and the educational benefits resulting from its use. This technology combines visual and auditory elements and is an effective tool for language education, suitable for students with learning difficulties. It can be applied in various educational contexts, from science and mathematics to art, and can enrich a simple narrative or provide personalized content. This paper is a significant contribution to the field, serving as a valuable resource for educators interested in integrating cutting-edge technologies into their pedagogical practices. New research in this direction should be done on the pedagogical use of talking pictures in education and the new frameworks for their integration.
