Component Combination Test to Investigate Improvement of the IHACRES and GR4J Rainfall–Runoff Models
Authors: Shin Mun-Ju , Kim Chung-Soo
Published: August 2021

Rainfall–runoff models are not perfect, and the suitability of a model structure depends on catchment characteristics and data. It is important to investigate the pros and cons of a rainfall–runoff model to improve both its high- and low-flow simulation. The production and routing components of the GR4J and IHACRES models were combined to create two new models. Specifically, the GR_IH model is the combination of the production store of the GR4J model and the routing store of the IHACRES model (vice versa in the IH_GR model). The performances of the new models were compared to those of the GR4J and IHACRES models to determine components improving the performance of the two original models. The suitability of the parameters was investigated with sensitivity analysis using 40 years’ worth of spatiotemporally different data for five catchments in Australia. These five catchments consist of two wet catchments, one intermediate catchment, and two dry catchments. As a result, the effective rainfall production and routing components of the IHACRES model were most suitable for high-flow simulation of wet catchments, and the routing component improved the low-flow simulation of intermediate and one dry catchments. Both effective rainfall production and routing components of the GR4J model were suitable for low-flow simulation of one dry catchment. The routing component of the GR4J model improved the low- and high-flow simulation of wet and dry catchments, respectively, and the effective rainfall production component improved both the high- and low-flow simulations of the intermediate catchment relative to the IHACRES model. This study provides useful information for the improvement of the two models.

Published: August 2021

Recent developments of Middle Eastern metropolitans, and the related soaring trend of population increase, is contemporary with the impacts of climate changes. This applies extra pressures to the centralized large-scale water treatment and distribution systems. Rainwater harvesting (RWH) for domestic urban activities can be a sustainable option of adapting with the rising demand of soft water in such an arid/semiarid area. A pilot system of rainwater draining and storage was constructed for alleviating parts of soft water scarcity in Mashhad, the second most populous city of Iran. Measurements were collected for two years at the drainage basin outlet and inside of a storage tank, which has been equipped for water harvesting purposes. We performed some preliminary stochastic analysis and evaluated probabilistic properties of the collected dataset, aiming to explain them with respect to the physical characteristics of the RWH system. Data clustering analysis confirmed that the quality of the water may change during rainwater draining and storage in the RWH tank. Particularly, sodium content of the sampled water in the drainage catchment illustrated higher variations, compared with the ones evaluated for the stored water in the reservoir tank. This can confirm that the quality of the stored water in the RWH reservoir is more stable than that obtained for each separate rainfall–runoff event. We assessed the potential of the harvested water in different consumption contexts, in light of some national and international water quality (physicochemical, biological, and toxic pollutants) guidelines. We relied on water quality indices (WQI) to interpret multiparametric properties of the collected rainwater from urban surfaces; consequently, the quality of the harvested water was categorized with moderate to almost good attributes. This makes it well suited for irrigation uses, which can play a relevant role against water shortages in the analyzed semiarid urban region. Otherwise, infiltration and treatments need to be performed if using harvested water for drinking consumptions (of human or livestock), some of which may be costly for local owners/uses. We provide some suggestions for improving efficiency of the system and enhancing the quality of the harvesting water.

Published: August 2021

The presence downstream of a dam of either rigid or erodible obstacles may strongly affect the flood wave propagation, and this complex interaction may lead to further dramatic consequences on people and structures. The open-source Lagrangian-based DualSPHysics solver was used to simulate a three-dimensional dam-break in a closed domain including an oriented obstacle that deflects the flow, thus increasing the complexity of fluid dynamics. By comparing numerical results with experimental data, the effectiveness of the model was evaluated and demonstrated with an extensive sensitivity analysis based on several parameters crucial to the smoothed particle hydrodynamics method, such as the resolution, the boundary conditions, and the properties of the interaction weight function. Charts and summary tables highlight the most suitable conditions for simulating such occurrences in the DualSPHysics framework. The presence of the obstacle, being also an opportunity for observation and study of complex fluid dynamics, opens the way to investigate the fluid interaction with solid objects involved in dam-break events and, possibly, to predict their effect with respect to the relative position between them and the flood and other relevant parameters. Finally, the numerical model presents a good overall agreement.

Published: August 2021

The present research depicts an analysis of the implementation of computational fluid dynamics (CFD) in the study of pumps such as turbines and PATs. To highlight the benefits of CFDs for PAT studies, results from both experimental tests have been compared to better understand the reproduction error phenomena. For this, data analysis used in successful models has been applied to determine variables and parameters, and to report a low relative error. The results show that most of the studies focused on fixed speed rotation with some cases of variable speed rotation. Furthermore, there is not enough information in the academic literature for PAT of axial and mixed flows with fixed and variable speed. Finally, turbulence models based on Reynolds average Navier–Stokes (RANS) have been used to simulate PATs with fixed speed rotation in most cases.
Assessing the Impact of DMAs and the Use of Boosters on Chlorination in a Water Distribution Network in Greece
Authors: Tsitsifli Stavroula , Kanakoudis Vasilis
Published: August 2021

Disinfection is one of the most important water treatment processes as it inactivates pathogens providing safe drinking water to the consumers. A fresh-water distribution network is a complex system where constant monitoring of several parameters and related managerial decisions take place in order for the network to operate in the most efficient way. However, there are cases where some of the decisions made to improve the network’s performance level, such as reduction of water losses, may have negative impacts on other significant operational processes such as the disinfection. In particular, the division of a water distribution network into district metered areas (DMAs) and the application of various pressure management measures may impact the effectiveness of the water chlorination process. Two operational measures are assessed in this paper: (a) the use of inline chlorination boosters to achieve more efficient chlorination; and (b) how the DMAs formation impacts the chlorination process. To achieve this, the water distribution network of a Greek town is chosen as a case study where several scenarios are being thoroughly analyzed. The assessment process utilizes the network’s hydraulic simulation model, which is set up in Watergems V8i software, forming the baseline to develop the network’s water quality model. The results proved that inline chlorination boosters ensure a more efficient disinfection, especially at the most remote parts/nodes of the network, compared to conventional chlorination processes (e.g., at the water tanks), achieving 100% safe water volume and consuming almost 50% less chlorine mass. DMAs’ formation results in increased water age values up to 8.27%, especially at the remote parts/nodes of the network and require more time to achieve the necessary minimum effective chlorine concentration of 0.2 mg/L. However, DMAs formation and pressure management measures do not threaten the chlorination’s efficiency. It is important to include water age and residual chlorine as criteria when optimizing water pressure and the division of DMAs.

Modelling of Humidity Dynamics for Open-Cathode Proton Exchange Membrane Fuel Cell
Authors: Chen Fengxiang , Zhang Liming , Jiao Jieran
Published: August 2021

The durability and output performance of a fuel cell is highly influenced by the internal humidity, while in most developed models of open-cathode proton exchange membrane fuel cells (OC-PEMFC) the internal water content is viewed as a fixed value. Based on mass and energy conservation law, mass transport theory and electrochemistry principles, the model of humidity dynamics for OC-PEMFC is established in Simulink® environment, including the electrochemical model, mass flow model and thermal model. In the mass flow model, the water retention property and oxygen transfer characteristics of the gas diffusion layer is modelled. The simulation indicates that the internal humidity of OC-PEMFC varies with stack temperature and operating conditions, which has a significant influence on stack efficiency and output performance. In order to maintain a good internal humidity state during operation, this model can be used to determine the optimal stack temperature and for the design of a proper control strategy.

Current state and prospects of the development of electromechanical processing for gas-thermal coatings
Authors: Ivannikov A.Yu.
Published: August 2021

The article presents an overview of the works on electromechanical processing of plasma coatings performed at the Institute of Metallurgy and Materials Science of the Russian Academy of Sciences and VolgSTU. The results of changes in the physical, mechanical and operational properties of plasma-sprayed coatings after electromechanical processing are analyzed. The main approaches in the field of electromechanical processing of gas-thermal coatings are outlined. The use of a cooling liquid to protect the zone of electric contact heating contributes to the preservation of the chemical composition of the coating. High rates of heating and cooling of the local area in the contact zone of the coating and the electrode tool lead to the fixation of the fast-quenched structure in the coating. An increase in the coating temperature as a result of resistive heating with simultaneous surface plastic deformation contributes to a decrease in surface roughness, compaction of the coating and the passage of diffusion welding along the boundaries of the sprayed particles. After electromechanical processing, the coating microhardness, cohesive and adhesive strength, corrosion and wear resistance are increased.

Published: August 2021

The article describes a new approach to solving the complex socio-economic problem of using production workers made redundant as a result of automation. It is shown that in modern conditions, it is possible to achieve a harmonious combination of social and economic results of production automation through the synthesis of activities of the two systems: the production system dedicated to manufacture where efficiency, among other factors, is determined by the number of redundant workers as a result of automation, and the creative system, which seeks the involvement of redundant workers in the improvement of creative potential of the production system. It is demonstrated that specific forms of enterprise synthesis are determined by the presence of proven solutions in one or another variant of the existence of «creative enterprises», including the promising form of «ergodynamic cooperatives».

Published: August 2021

The purpose of this article is to make a proposal for the control of heno motita (Tillandsia recurvata), based on the analysis of its environmental function within the atmospheric basin of Tula, to contribute to the solution of a state forest problem. Its approach is quantitative experimental since it seeks to explain how the application of 5% acetic acid and 80g / l sodium bicarbonate affects the emergence of new shoots and the Hay Motita plant directly, as well as to identify the function that said plant fulfills. within the microenvironment. The findings show that heno motita is a plant that seeks a support to capture nutrients from the air, however, shading causes the host plant to decrease its efficiency in capturing energy, likewise there is mechanical damage due to its weight and a chemical one since it secretes an allelopathic substance that damages the new shoots. On the other hand, Tillandsia recurvata "sequesters" particles of different materials such as heavy metals in its trichomes, thus contributing to the sanitation of the atmosphere. Finally, the steps to follow to develop a specific management program are proposed.

Interference-Aware Accurate Signal Recovery in UHF Band Reuse-1 Cellular OFDMA Downlinks
Authors: K Giridhar , Mohan M V Abhay
Published: August 2021

Reuse-1 systems operating in the sub-1 GHz UHF band are limited by substantial co-channel interference (CCI). In such orthogonal frequency division multiple access (OFDMA) cellular systems, the inter-sector or inter-tower interference (ITI) makes accurate signal recovery quite challenging as sub-1 GHz bands only support single-input single-output (SISO) links. Interference-aware receiver algorithms are essential to mitigate the ITI in such low-frequency bands. Such algorithms enable ubiquitous mobile broadband access over the entire homeland, say with >95% geographical coverage with quality of service guarantees. One element of the interference-aware signal recovery is the least-squares-based joint channel estimation scheme that uses non-orthogonal pilot subcarriers. This estimator is then compared with a variant that uses orthogonal pilot subcarriers to bring out the advantage of this joint estimator. It is shown that the proposed joint estimator requires fewer pilots to be well-determined when compared to its under-determined orthogonal counterpart. Moreover, it is easy to implement and does not require any knowledge of channel statistics. This work also derives a compensation factor needed for the interference-aware detector in the presence of inter-carrier interference (ICI) originating from multiple transmitters. Simulation results show that the proposed joint channel estimator outperforms traditional estimators at moderate to high frequency selectivity. The proposed compensation factor to the joint detector is found to be essential for recovering the transmitted signal in the absence of phase-tracking pilots.
A Very Low Reference Spur Phase Offset Technique in Fractional-N Charge pump PLLs
Authors: Thambidurai Chembiyan
Published: August 2021

Fractional-N charge pump phase locked loops (PLLs) suffer from the problem of increased in-band phase noise due to charge pump non-linearity caused by UP/DN chargepump current mismatch. Existing techniques that resolve this problem by introducing phase offset between reference and divide signals cause large reference spurs or increase jitter at PLL output. A very low reference spur phase offset technique is proposed in this work. It produces the lowest reference spurs compared to previously published works. A detailed comparison of the reference spurs caused by the different techniques to introduce phase offset is presented. Simulation results show that the reference spur level generated at the PLL output after applying the proposed technique is 26 dB lower than the existing techniques in the presence of 5% chargepump current mismatch.

Introduction: To investigate the effects of a multiprofessional approach on anthropometric parameters and body composition and the level of food processing in adolescents.
Methods: Twelve overweight/obese male adolescents between 13-17 years old participated in a series of 12-week multiprofessional interventioms led by physical education, nutrition and psychology professionals. The participants were assessed before the intervention as well as at 6 and 12 weeks into it. Anthropometric assessments were performed, including body weight, stature and body mass index; body composition, with fat mass (FM), body fat (%BF), skeletal muscle mass (SMM) and resting metabolic rate (RMR) and by filling in a three-day food record, in order to calculate the ingested foods, by the level of processing of the food: fresh, minimally processed, processed and ultra-processed. 
Results:  No differences were observed for the anthropometric parameters performed at different stages (p>0.05). Reductions for FM and %BF and increases in SMM and RMR (p<0.05) were identified, all after 12-week of the intervention. There was an increase in the consumption of natural foods/g, and an increase in the caloric consumption of processed foods/kcal, after 12-week of interventions (p<0.05).
Conclusion: The model resulted in decreases in FM and %BF, an increase in SMM, RMR, natural foods/g and processed foods/kcal.

The crossing was carried out on the CAPES Journals Portal, using the health descriptors: Sustainable Development, Health Care, Adolescent, Sustainable Development Indicators, in the databases MEDLINE, LILACS, Web of Science, Scielo. He listed as inclusion criteria: complete works, available and in Portuguese, English, and Spanish. Exclusion criteria: articles that do not provide abstracts, editorials, theoretical reflections, duplicate studies, experience reports, reviews, monographs, and abstracts in the annals of events. All crossings were performed in a foreign language, English, using the Boolean operator AND. The final sample consisted of 12 articles.
Results: It points to the implementation of sustainable practices to the adolescent public that can break with punctual and fragmented health care, emphasizing the expansion of practices aimed at access to health services that can actually meet their real health needs, income generation programs, and adoption of healthy eating, equity in health services and health education. It shows that the implementation of sustainable practices presents itself as a tool to achieve health promotion and as a paradigm shift in adolescent health care.
Conclusion: There was a need for health policies and actions for adolescents that can contribute to the development of health care aimed at health promotion. Thus, it evidences the need for disruption of specific health practices focusing only on the disease, making it a challenge to develop sustainable practices for adolescents regarding changes in actions in a health-promoting perspective.

Background: Individuals post-stroke commonly presents functional and cardiorespiratory deficits besides a physical inactivity lifestyle in the chronic phase of disease. Considering this, there is a hypothesis that hemodynamic responses could be affected by motor, cognitive and cardiorespiratory deficits during the aerobic exercise. In order to identify functional conditions that can influence the aerobic performance of these individuals, correlations between functional variables and hemodynamic responses during and after the aerobic exercise were studied. As a secondary purpose, the ability of return to hemodynamic resting state were also analyzed.
Methods: In this experimental study, after being evaluated about their motor and cognitive function, balance and prognosis, forty participants underwent a 30-minute aerobic exercise session on a treadmill. Training heart rate, arterial blood pressure, oxygen pulse saturation, heart rate, and respiratory rate were measured before begin the exercise session, every five minutes during the exercise and five minutes after it. 
Results: Cardiorespiratory parameters within normality limits in all phases of the exercise and the capacity of returning to the resting state were observed. Moderate inverse correlations were found between Berg Scale and oxygen pulse saturation (r=-0.401, p=0.01), between MMSE and diastolic blood pressure (r=-0.406, p=0.009), age and diastolic blood pressure (r=-0.435, p=0.005) and between injury time and RR (r=-0.454, p=0.003). Relationship between the lesion side and the 20 minute phase of aerobic exercise was also observed (p=0.042).  
Conclusion: Post- stroke individuals present moderate correlation between hemodynamic and respiratory responses during aerobic exercise and balance, muscle strength, injury time, age and side of lesion. They also have the capacity to return to their cardiorespiratory and cardiovascular resting state right after the activity besides their cardiorespiratory deficits.

Introduction: Autistic Spectrum Disorder (ASD) is part of neurodevelopmental disorders, which are behavioral and cognitive. These symptoms appear according to the child's development, however, most of the time, they present themselves before the age of three, and they may evolve to greater intensities or not.
Objective: To analyze the experience of families with children with Autistic Spectrum Disorder.
Methods: Exploratory study with a qualitative approach carried out at the Associação de Pais e Amigos dos Excepcionais (Association of Parents and Friends of the Exceptional/APAE). 46 families and 10 professionals participated in the study. For the analysis of the results, the technique of content analysis proposed by Bardin was used. The research project for this study was approved by the Ethics Committee for Research with Human Beings under opinion No. 3172.942 on February 27, 2019.
Results: It was evident that the family is an important instrument for the care of children with ASD and, for this reason, it should be seen in an integrated and not fragmented way in care, thus revealing the need to promote actions that take care of the caregiver and not just of the child itself, because as seen, every process that goes from birth to diagnosis and treatment of the child requires changes that can also bring harm to the health of the family.
Conclusion: The experience of families of children with ASD goes through phases of acceptance and adaptation and depends on the interaction and assistance of professionals so that they can, despite life changes, perceive them as important in promoting the child's life from the motor and cognitive interaction with society.

Introduction: Electronic devices have been used by increasingly younger people, leading researchers to investigate the impact of these technologies on the health of developing children.
Objective: To investigate the impact of smartphone use on the postural control of Brazilian children 6 to 9 years old.Methods: This cross-sectional study was conducted with 278 children from public schools in Goiânia (Goiás, Brazil). The children were assessed in an orthostatic posture with the computerized baropodometry system in three conditions: eyes open, eyes closed, and using a free smartphone application.
Results: The children were 8.36 years old on average, 82% of them were well-nourished, and had a daily mean screen time of 2 hours. The postural control analyses revealed that the children made greater postural adjustments with their eyes closed than with them open. When using the smartphone application, the postural adjustments were similar to those with eyes closed. In the stabilometry, the postural displacements made by the children behaved similarly to the static assessment only in total feet surface area.
Conclusion: Smartphone use and absence of visual stimulus in the orthostatic position caused postural instability in children 6 to 9 years old. These findings can contribute to understanding the impact of technologies on children’s development of balance in daily tasks.

Background: The current concept of Health Promotion includes an interdisciplinary approach from various sectors of society. However, many themes related to health promotion are still restricted to prevention and a biologic approach to disease, as is presumably the case with stress.
Objectives: This study aims to analyze the concepts of health promotion associated with stress exposed by the print media.
Methods: It is a study in which it was carried out the qualitative media analysis of 727 news from printed newspapers, dated from 2015 to 2017. The concepts of Health Promotion related to stress, found in the approaches on the subject in the media were: 1- Early Health Promotion: absence of disease and birth of the term (past); 2 - Health Promotion as primary prevention (present); 3- Expanded Health Promotion (what is expected in the future).
Results: The study contributes to stimulating society's leading role in health promotion and brought the novelty of the print media's approach to stress. The study shows that the most recent concepts of health promotion linked to stress are little discussed in the print media. The study suggests, with its originality, a current reflection on stress and the evolution of the meanings of Health Promotion.
Conclusion: It was observed that the media still approaches the stress theme in a restricted, biologicist, medicalized, prescriptive way, and focused on commercial interests, reinforcing the need for public policies aimed at Health Promotion comunication.
