Acute Post-Exercise Recovery Strategies in Cycling: A Review
Authors: Overmayer Ryan , Tavares Francisco , Driller Matthew William
Published: February 2020

Cycling events often include multiple races a day or racing over consecutive days. Congested competition schedules and increased training load have led to the implementation of recovery strategies; with the goal of alleviating post-exercise fatigue and enhancing subsequent performance. This review aims to review the efficacy of recovery strategies used following different cycling events. Compression garments have been shown to improve subsequent 30s – 30min mean cycling power and 5-min max cycling power, while cold water immersion may improve 5-15s sprint cycling power output, 1-15min time trial (TT) total work performed and mean power output in hot and humid conditions. Cold water immersion was also more beneficial than active recovery at improving total work performed. Contrast water therapy could increase 15s – 15min TT work performed and sprint mean and peak power output. Similarly, active recovery has been shown to improve power measures and time to completion. Conversely, hot water immersion appears to be detrimental to sprint power output and TT power output over consecutive days. Thermoneutral water immersion appears beneficial for improving average cycling speed and time to completion during a 20-km TT, where humidification therapy and sports massage are beneficial at improving sprint and middle duration time trial performance. A combination of recovery strategies appear more beneficial than stand-alone strategies and various combinations should be explored further.

Authors: Huda Reaz Mahmud , Mozaffor Miliva , Alam Mohammad Ashraful , Hossain Md Delwar
Published: February 2020

Background:Metabolic syndrome is a matter of immense public health concern. Based on ethnicity, its associationand impact on ischemic heart diseases like myocardial infarction (MI) is a current topic of research.Objective: To evaluate the clinical impact of metabolic syndrome on patients with acute ST-elevation myocardial infarction (acute STEMI) in a Bangladeshi population.Methods: This prospective observational study was done in the Department of Cardiology of the National Institute of Cardiovascular Diseases (NICVD), Dhaka, Bangladesh, from July to December of 2013.A total 233 patient were selected for data collection; 109 were in group I (acute STEMI patients with metabolic syndrome), while 124 werein group II (acute STEMI patients without metabolic syndrome). Initial evaluation of the patients done by history and clinical examination was recorded in the preformed data collection sheet.Baseline investigations like ECG, CK(MB), lipid profile, fasting blood sugar, serum creatinine andechocardiography were done. Coronary angiogram (CAG) was done in the Cardiac Cath-Lab facility of the same hospital.The patients’ outcomes were observed until they were discharged from the hospital.Results: Heart failure was significantly more in patients of group I than group II (46.79% vs. 20.97%; p<0.001). Among the patients who underwent coronary angiogram (CAG), the mean Friesinger score was 9.7±2.5 in group I and 7.1±3.3 in group II, which was statistically significant (p<0.05), and indicated more chances of severe coronary artery disease in group I patients. However, mortality rate was not statistically significant in between group I and group II (16.51% vs 12.09%; p=0.415). Both in heart failure and coronary artery disease, among all the components of metabolic syndrome, hyperglycemia had the strongest association followed by low HDL and high triglyceride (TG). However, raised BP had much less significant association with development of heart failure or coronary artery disease.Conclusion:Our data suggest that the acute ST-elevation myocardial infarction patients with metabolic syndrome have poor disease prognosis and in-hospital outcome than those without metabolic syndrome.However, the use of a simple risk score based on those biomarkers may identify a high-risk group to initiate preventive measures for cardiovascular health of the country’s population.International Journal of Human and Health Sciences Vol. 04 No. 03 July’20 Page : 215-221

Authors: Ekenci Kübra Damla , Türker Perim F. , Ercan Aydan
Published: February 2020

Amaç: Bu çalışmanın amacı, hemodiyaliz hastalarının beslenme alışkanlıklarının belirlenmesi ve sosyo-demografik özellikleri ile beslenme durumları arasındaki ilişkinin irdelenmesidir.

Bireyler ve Yöntem: Çalışma 23-85 yaş arasında 128 (71 kadın, %55.5) hemodiyaliz hastası üzerinde yürütülmüştür. Hastaların demografik özellikleri ve beslenme alışkanlıkları anketle belirlenmiştir. Antropometrik ölçümleri araştırmacı tarafından alınmış ve biyokimyasal parametreler hasta dosyasından elde edilmiştir. Subjektif Global Değerlendirme (SGD), Nutrisyonel Risk Taraması-2002 (NRS-2002) ve Malnütrisyon Inflamasyon Skoru (MİS) kullanılarak malnütrisyon durumu saptanmıştır.

Bulgular: SGD’ye göre hastaların %8.6’sı ağır, %15.6’sı ise hafif-orta derecede malnütrisyonlu iken, NRS-2002’ye göre hastaların %21.9’unun beslenme riskine sahip olduğu belirlenmiştir. Malnütrisyon inflamasyon skoruna göre (MİS) kadın ve erkek hastaların MİS ortanca değeri sırasıyla 6 ve 5 puan olarak bulunmuştur (p>0.05). NRS-2002’ye göre malnütrisyon riski olan hastaların %64.2’si ilkokul ve altı eğitim düzeyine sahiptir. SGD’ye göre ise hafif-orta derece malnütrisyonlu olan hastaların %50’sinin ilkokul ve altı eğitim düzeyine sahip olduğu, ağır derece malnütrisyonlu olan hastaların %45.5’inin okur yazar olmadığı, %36.4’ünün ilkokul mezunu olduğu saptanmıştır. Hastaların eğitim düzeylerine göre malnütrisyon durumunun istatistiksel olarak farklı olduğu bulunmuştur (p<0.05). MİS puanları ile yaş, eğitim ve gelir düzeyleri arasında ilişki saptanmamıştır (p>0.05).

Sonuç: Hemodiyaliz hastalarının büyük bir çoğunluğunun eğitim ve gelir düzeyi düşüktür. Eğitim düzeyi düşük hastalarda malnütrisyon riski ve varlığı daha yüksektir. Hastalarda malnütrisyon riskinin belirlenmesinde ve yapılacak beslenme müdahalelerinde hastaların sosyo-demografik özelliklerinin de dikkate alınmasının gerekli olduğu düşünülmektedir.

Digital media ethnographers on the move – An unexpected proposal
Authors: Sumial Johanna , Tikka Minttu
Published: February 2020

This article explores what digital media ethnography as a methodological approach can offer to the study of contiguous media events with an unexpected, violent and fluid nature. Emphasising the role of media events in the present organisation of social life, we as digital media anthropologists acknowledge the tendency in the current digital media environment to eventise and spectacularise social life. This development serves the power-related purposes of attention seeking and public recognition in the digital world. The article is structured as follows: first, we provide a brief outline of the field of digital media ethnography in relation to the study of media event; second, we identify what we claim are three key methodological dilemmas in applying digital media ethnography to the study of today’s digitally circulating media events (scale, mobility and agency) and reflect on them in the context of our methodological positioning; third, we conclude this article by considering some epistemological and ontological implications of this methodological endeavour in relation to what can be called the ‘meta-field’ and the related instability in current digital research.

Authors: Плетенець В. М.
Published: February 2020

Стаття присвячена висвітленню можливостей використання слідчим критичного мислення в умовах протидії розслідуванню. Наголошується, що процедури та стратегії критичного мислення мають використовуватися для вирішення неординарних практичних завдань, котрі неможливо вирішити машинально, із застосуванням наявних знань та умінь. Звертається увага на те, що набуття слідчими навичок оцінки кожного розслідуваного кримінального провадження сприятиме формуванню такого якісного рівня, що не дозволить припуститися помилок розслідування. Підкреслюється, що постійний тиск з боку зацікавлених осіб не повинен впливати на рішення слідчого, які мають бути самостійними та ґрунтуватися на критичному аналізі матеріалів провадження.

Antonovsky’s Short 13-Items SOC Scale in a Swedish Community Cohort-Considering the Selection of the 13 Items from the Original 29 SOC Scale
Authors: Mattisson Cecilia , Gräsbeck Anne , Bogren Mats , Horstmann Vibeke
Published: February 2020

Background: Antonovsky’s Sense of Coherence (SOC) scale, published with 29 items, is considered a social concept, also used in mental health research. A scale using only 13 of the items has been suggested, without explanation as to how these 13 items were selected.
Aim: To compare how total scores based on 29 and 13 and the remaining 16 items could be explained by sociodemographic and mental health factors and to explore how each of the 13 items relates to these factors in comparison to the remaining 16 items.
Methods: The full SOC questionnaire was completed by 1,164 subjects in the Lundby cohort study in 1997. Using linear regression, socio-demographic factors were evaluated as predictors for the sum-scores of the 29 and 13 items. Relationships to the socio-demographic factors and mental disorders were evaluated for each item; the results for the 13 items were compared to the results for the remaining 16 items. The distributions of the responses for the 13 items were compared to the distributions of the responses for the 16 items.
Results: The sum-scores related differently to age; generally, positively among the 13 items, but negatively for the 16 excluded items. Differences between the 13 and the remaining 16 items were observed in relations to gender and partnership, somewhat less to socio-economic status, minor differences in relation to mental disorders. The distributions of the responses of the items were highly negatively skewed, more so among the 13 items.
Conclusion: No obvious explanation for the selection of the 13 items was found. Different results may be obtained regarding associations to socio-demographic factors depending on whether the 13 items or all 29 items are used. The highly skewed distributions of responses indicate that more research would be valuable in order to assess SOC.

Published: February 2020

A vactrain (or vacuum tube high-speed flying train) is considered as a novel proposed rail transportation approach in the ultra-high-speed scenario. The maglev train can run with low mechanical friction, low air resistance, and low noise mode at a speed exceeding 1000 km/h inside the vacuum tube regardless of weather conditions. Currently, there is no research on train-to-ground wireless communication system for vactrain. In this paper, we first summarize a list of the unique challenges and opportunities associated with the wireless communication for vactrain, then analyze the bandwidth and Quality of Service (QoS) requirements of vactrain’s train-to-ground communication services quantitatively. To address these challenges and utilize the unique opportunities, a leaky waveguide solution with simple architecture but excellent performance is proposed for wireless coverage for vactrains. The simulation of the leaky waveguide is conducted, and the results show the uniform phase distribution along the horizontal direction of the tube, but also the smooth field distribution at the point far away from the leaky waveguide, which can suppress Doppler frequency shift, indicating that the time-varying frequency-selective fading channel could be approximated as a stationary channel. Furthermore, the train-to-ground wireless access architectures based on leaky waveguide are studied and analyzed. Finally, the moving scheme is adopted based on centralized, cooperative, cloud Radio Access Network (C-RAN), so as to deal with the extremely frequent handoff issue.
Decomposition Analysis of the Carbon Emissions of the Manufacturing and Industrial Sector in Thailand

Published: February 2020

Since the 1990s, CO2 emissions have increased steadily in line with the growth of production and the use of energy in the manufacturing sector in Thailand. The Logarithmic Mean Divisia Index Method is used for analysing the sources of changes in CO2 emissions as well as the CO2 emission intensity of the sector in 2000–2018. On average throughout the period, both the amount of CO2 emissions and the CO2 emission intensity increased each year relative to the baseline. The structural change effect (effect of changes of manufacturing production composition) reduced, but the intensity effect (effect of changes of CO2 emissions of individual industries) increased the amount of CO2 emissions and the CO2 emission intensity. The unfavourable CO2 emission intensity change came from the increased energy intensity of individual industries. The increased use of coal and electricity raised the CO2 emissions, whereas the insignificant change in emission factors showed little impact. Therefore, the study calls for policies that decrease the energy intensity of each industry by limiting the use of coal and reducing the electricity used by the manufacturing sector so that Thailand can make a positive contribution to the international community’s effort to achieve the goal of CO2 emissions reduction.

Published: February 2020

It is widely accepted that conventional boost algorithms are of low efficiency and accuracy in dealing with big data collected from wind turbine operations. To address this issue, this paper is devoted to the application of an adaptive LightGBM method for wind turbine fault detections. To this end, the realization of feature selection for fault detection is firstly achieved by utilizing the maximum information coefficient to analyze the correlation among features in supervisory control and data acquisition (SCADA) of wind turbines. After that, a performance evaluation criterion is proposed for the improved LightGBM model to support fault detections. In this scheme, by embedding the confusion matrix as a performance indicator, an improved LightGBM fault detection approach is then developed. Based on the adaptive LightGBM fault detection model, a fault detection strategy for wind turbine gearboxes is investigated. To demonstrate the applications of the proposed algorithms and methods, a case study with a three-year SCADA dataset obtained from a wind farm sited in Southern China is conducted. Results indicate that the proposed approaches established a fault detection framework of wind turbine systems with either lower false alarm rate or lower missing detection rate.
Experimental Study of Sand Particle Deposition on a Film-Cooled Turbine Blade at Different Gas Temperatures and Angles of Attack
Authors: Zhang Fei , Liu Zhenxia , Liu Zhengang , Diao Weinan
Published: February 2020

Particle deposition tests were conducted in a turbine deposition facility with an internally staged single-tube combustor to investigate the individual effect of the gas temperature and angle of attack. Sand particles were seeded to the combustor and deposited on a turbine blade with film-cooling holes at temperatures representative of modern engines. Fuel-air ratios were varied from 0.022 to 0.037 to achieve a gas temperature between 1272 and 1668 K. Results show that capture efficiency increased with increasing gas temperature. A dramatic increase in capture efficiency was noted when gas temperature exceeded the threshold. The deposition formed mostly downstream of the film-cooling holes on the pressure surface, while it concentrated on the suction surface at the trailing edge. Deposition tests at angles of attack between 10° and 40° presented changes in both deposition mass and distribution. The capture efficiency increased with the increase in the angle of attack, and simultaneously the growth rate slowed down. On the blade pressure surface, sand deposition was distributed mainly downstream of the film-cooling holes near the trailing edge in the case of the small angle of attack, while it concentrated on the region around the film-cooling holes near the leading edge, resulting in the partial blockage of holes, in the case of the large angle of attack.
A Lifetime-Enhancing Method for Directional Sensor Networks with a New Hybrid Energy-Consumption Pattern in Q-coverage Scenarios
Authors: Peng Song , Xiong Yonghua
Published: February 2020

An important issue in directional sensor networks (DSNs) is how to prolong the network lifetime in Q-coverage scenarios where each target point may have different coverage requirements. When the Q-coverage requirement is met, it is an effective way to maximize the network lifetime by controlling energy consumptions. Unlike the existing results where only the sensing energy consumption is considered, this paper proposes a new hybrid energy consumption pattern, which reflects the reality of energy consumptions more closely. In such a pattern, both sensing and communication energy consumptions are considered. By combining scheduling and clustering technologies to control these two kinds of energy consumptions in each round, a new lifetime-enhancing method (NLEM) is devised to prolong the network lifetime. First, a sensing direction scheduling algorithm for Q-coverage is proposed to make different sensing direction sets meet the coverage requirement of each target point. Then, a new cluster head selection algorithm and an inter-cluster communication algorithm are developed to select an optimal cluster head set and achieve multi-hop communication, respectively. Simulation results demonstrate the effectiveness of the NLEM in prolonging the network lifetime for DSNs in Q-coverage scenarios.

Published: February 2020

The industrial sector dominates the global energy consumption and carbon emissions in end use sectors, and it faces challenges in emission reductions to reach the Paris Agreement goals. This paper analyzes and quantifies the relationship between industrialization, energy systems, and carbon emissions. Firstly, it forecasts the global and regional industrialization trends under Representative Concentration Pathway (RCP) and Shared Socioeconomic Pathway2 (SSP2) scenarios. Then, it projects the global and regional energy consumption that aligns with the industrialization trend, and optimizes the global energy supply system using the Model for Energy Supply Strategy Alternatives and their General Environmental Impact (MESSAGE) model for the industrial sector. Moreover, it develops an expanded Kaya identity to comprehensively investigate the drivers of industrial carbon emissions. In addition, it employs a Logarithmic Mean Divisia Index (LMDI) approach to track the historical contributions of various drivers of carbon emissions, as well as predictions into the future. This paper finds that economic development and population growth are the two largest drivers for historical industrial CO2 emissions, and that carbon intensity and industry energy intensity are the top two drivers for the decrease of future industrial CO2 emissions. Finally, it proposes three modes, i.e., clean supply, electrification, and energy efficiency for industrial emission reduction.
Quantification of the Energy Storage Contribution to Security of Supply through the F-Factor Methodology

Published: February 2020

The ongoing electrification of the heat and transport sectors is expected to lead to a substantial increase in peak electricity demand over the coming decades, which may drive significant investment in network reinforcement in order to maintain a secure supply of electricity to consumers. The traditional way of security provision has been based on conventional investments such as the upgrade of the capacity of electricity transmission or distribution lines. However, energy storage can also provide security of supply. In this context, the current paper presents a methodology for the quantification of the security contribution of energy storage, based on the use of mathematical optimization for the calculation of the F-factor metric, which reflects the optimal amount of peak demand reduction that can be achieved as compared to the power capability of the corresponding energy storage asset. In this context, case studies underline that the F-factors decrease with greater storage power capability and increase with greater storage efficiency and energy capacity as well as peakiness of the load profile. Furthermore, it is shown that increased investment in energy storage per system bus does not increase the overall contribution to security of supply.
