For whom is data literacy empowering? An awareness-action typology
Authors: Mund Shiri , Bergner Yoav
Published: October 2023

Building on recent empowerment perspectives on data literacy, we examine how students and working adults talk about their understanding of data and report on their own personal-data-related practices. Through a deductive and inductive analysis of interviews with 19 subjects ranging from middle school to middle age, we find that awareness and action with respect to data consumption and production do not necessarily increase in tandem. For example, being more aware of the data that can be used to track them does not make individuals more likely to take action to manage their personal data. While some feel anxiety about the gap between knowledge and action, others resolve the tension by choosing not to care. These findings are synthesized in a typology of personas in the space of data awareness and action. We investigate the relationship between age and educational attainment with location in this awareness-action space and discuss implications for data literacy education.

Authors: Lien Quan Thi Ai , Duy Pham Vu Khuong
Published: October 2023

This study was carried out from 9/2022 to 2/2023, at Can Tho University, Vietnam. This study evaluated seedling stages’ salt tolerance in nutrient solution using three electrical conductivity (EC) salt concentrations of 9.38, 12.50, and 15.63 dS/m with fifteen traditional rice varieties. Five traditional salt-tolerant rice varieties at the seedling stage (level 5) at 15.63 dS/m were selected. Furthermore, we evaluated salt tolerance at EC 9.38, 12.50, and 15.63 dS/m in the vegetative and reproductive stages of seven rice varieties (a tolerant variety, Doc Phung, a sensitive variety, IR28, and five rice salt-tolerant varieties were selected at seedling stage). This study showed that an increase in EC concentrations in the soil significantly reduced plant height, panicle/plant, panicle length, a 1000 grain weight, and yield. The addition of 9.38 dS/m EC can distinguish tolerance and sensitive genotypes. The grain yield of sensitive genotypes decreased by 90%–100% at 9.38 dS/m EC, whereas the tolerant genotypes showed <60% in grain yield reduction. Selected traditional rice varieties of Nang Cha Ran, Nep Than, Trang Lun, Gie Hanh, and Nang Tich were salt tolerant at their seedling stage and vegetative and reproductive stages were at EC 9.38 dS/m.
Analysis of electrostatic filter to mitigate ash diffusion into engine
Authors: Shahneh A Zare
Published: October 2023

Between March and June 2010 a series of volcanic events at Eyjafjallajökull in Iceland caused enormous disruption to air travel across Western Europe. The disruptions started over an initial period of six days in April 2010. About 20 countries closed their airspace to commercial jet traffic and it affected approximately 10 million travelers. Volcanic ash has been caused grounding of many aircraft as a source of possible damage to aircraft engines. The projected technical strategy, an electrostatic precipitator (ESP), was tailored for the high bypass turbofan engine model PW4000 in this study. It was based on the standard two-stage ESP but designed with the PW4000 engine. The innovative ESP prototype is primarily made up of a hexagram structure of six discharge electrode plates and three circular collecting electrode rings. An aerodynamic verification was conducted through computational fluid design (CFD). It built a 20-meter wind tunnel and placed the engine with ESP in the centre of it. A particle-laden atmosphere was created in the simulation using a discrete phase model (DPM) to replicate volcanic ash injection into clean air. From the results, it has a clear aerodynamic impact near the engine's intake, although the effect is small and may be ignored after the engine fans. Additionally, a CFD electrostatic verification was generated with a voltage of 20000 V, and the contour of the electric potential is perfect distributed, suggesting that an electric field can be adequately given by this ESP configuration design. Therefore, the simulation results of the new ESP layout would have allowed drawing conclusions about the electrostatic filter's ability to reduce volcanic ash intake in an engine with high aerodynamic performance.

Published: October 2023

Introduction. Mastering the micro-plasma powder deposition (MPWD) technology for refurbishing parts of nickel-based super alloy aircraft gas turbine engine (GTE) has been remaining a relevant task of the Ukrainian air craft industry for, at least, 15 last years.Problem Statement. MPWD or subsequent heat treatment of GTE parts made of nickel-based super alloy after long-term operating hours, with high γ'-phase content, might reveal increased cracking susceptibility. The search for ways to optimize the welding deposition technology has shown the necessity to scrutinize the positive technological effect of rational choice of the quality and content of process (shielding, plasma and transporting) gases.Purpose. To study the effect of process gas content on the heat source parameters, the conditions of the formation of deposited metal and its quality.Material and Methods. Comparative study of the micro-plasma (PPS04 plasmatron, UPNS-304M welding machine) and TIG (VSVU-315 power source) arc heat parameters depending on welding current and process gas has been conducted by the conventional flow calorimetry technology. Comparative estimation of the total work piece heat input parameters has been made based on the previously developed methodology with registering the welding current parameters based on m-DAQ14 analog-to-digital converter (ADC).Results. The comparative research during MPWD of sample parts has shown that the content and quality of process gases can significantly (up to 2.5 times) affect the amount of heat transferred into the work piece and, respectively, the possibility to provide the technological strength of “base-deposited metal” welded joint.Conclusions. The industrial MPWD process optimization by the criteria of work piece heat input parameters, technological strength of “base-deposited metal” welded joint and filler powder consumption,by means of increasing argon (plasma and transporting gas) quality by other gases impurities content and switch to 90% Ar + 10% Н2 argonhydrogen mixture shielding gas has been established to be promising and expedient way to solve the problem.

Authors: Aygün Cihan , Çakır-Atabek Hayriye
Published: October 2023

Background and Study Aim. Many findings have demonstrated that several life-threatening diseases, including cardiovascular diseases, obesity-related diseases, and certain types of malignancies, can be prevented by exercise. Reactive oxygen species (ROS) may be the direct or associated factor that causes or prevents these diseases. It is well known that a strenuous and high-intensity acute exercise increases ROS production and intensifies oxidative stress. At this point, the importance of physical activity (PA) and exercise in reducing oxidants and improving antioxidant defense system increasing. The purposes of the current study were to investigate the short term (acute) and long term (chronic) effects of active video gaming (AVG) on oxidative stress indices.
Material and Methods. Nine healthy male university students participated in the study. The participants played an AVG as vigorous physical activity (MET > 7) for 20 minutes, three days a week, for 4 weeks. Each participant completed twelve game sessions. Blood samples were obtained just before (after 10 min rest in seated position) and immediately after the game session on the first and the last day of the study. Total oxidant and antioxidant status (TOS and TAS) were determined using an automated measurement method, and the oxidative stress index (OSI) was calculated. Total oxidized guanine (TOG) and superoxide dismutase (SOD) activity were analyzed using commercial kits (Cayman Chemical). Data were analyzed with dependent t-tests and significance was accepted as p<0.05.
Results. The SOD activity significantly decreased after the AVG on the first day (4.78 ± 1.26 vs. 3.81 ± 1.80; p=0.026). The TOS (6.62 ± 1.09 vs. 7.30 ± 1.24) and TOG (9.26 ± 2.69 vs. 9.78 ± 2.62) levels increased on the first day, but these alterations were not significant. Additionally, no significant acute changes were observed for the last day of the study
Conclusions. The 4-week active video gaming practices did not change the oxidative stress status of pre-game, chronically. Four-week-AVG practice did not change oxidative stress indices significantly in rest.

Authors: Özsarı Arif , Görücü Alpaslan
Published: October 2023

Background Study Aim. This study aimed to investigate the impact of moral decision-making attitudes among athletes in various sports on their psychological well-being.
Material and Methods. A total of 345 active, licensed athletes (also students) participated in this study, with a mean age of 19.62 years (215 females and 130 males). The sports represented included athletics, badminton, basketball, boxing, fencing, football, wrestling, handball, hockey, judo, kickboxing, table tennis, taekwondo, wheelchair basketball, volleyball, and swimming. In addition to descriptive statistics, correlation and regression analyses were conducted within the framework of a relational model.
Results. The study revealed significant relationships between different sub-dimensions of the moral decision-making attitude scale and psychological well-being. Specifically, a significant negative relationship (r = -0.162, p < 0.001) was observed between adopting cheating, a sub-dimension of the moral decision-making attitude scale, and psychological well-being. Conversely, a significant positive relationship (r = 0.158, p < 0.001) was found between protecting fair competition, another sub-dimension of the moral decision-making attitude scale, and psychological well-being. It was determined that adopting cheating had a significantly negative effect on psychological well-being (β = -0.188, p < 0.001), while protecting fair competition had a positive effect (β = 0.183, p < 0.001).
Conclusions. This study suggests that athletes experience a negative impact on their psychological well-being when they engage in cheating as part of their moral decision-making attitudes. Conversely, their psychological well-being benefits from their commitment to fair competition. It can be argued that athletes' moral responsibilities contribute to their psychological resilience and well-being.
Physical activity and academic performance in students from same primary education school
Authors: Garcia-Jimenez Jose Vicente
Published: October 2023

Background and Study Aim. Recent researches has demonstrated the relationship between physical activity levels and academic performance in schoolchildren. Most of them have sampled students from different schools and cities. Sometimes academic performance was influenced by other factors such as the type of teaching, the teaching staff or, for example, the assessment system. This research has tried to associate the practice of out-of-school physical activity with academic performance in a group of students, with the peculiarity that they all belonged to same Elementary school.
Material and Methods. 120 students (67 boys and 53 girls), aged between 8 and 12 years, participated in this study once their parents or guardians were informed about the characteristics of the study. Academic performance was calculated from the average grades provided by their teachers in the first term. Physical activity levels were calculated using the APALQ questionnaire, categorising students into two types: active or sedentary. In the presence of a normal distribution, the difference between groups was obtained using Chi-Square and Student's t-test. In those cases where the distribution was not normal, comparison was carried out using the Mann Withney U.
Results. The analysis of results showed that active students obtained significantly higher grades than sedentary students (8.15±1.17 vs. 7.35±1.15; p=0.042). This circumstance is maintained when analysing the results according to the students' gender, although it is only significant in the case of girls (8.08±1.22 vs 7.03±0.87; p=0.036).
Conclusions. The practice of physical activity during non-school hours had a positive influence on the academic performance of the students analysed, even though they were from the same school.

Published: October 2023

Background and Study Aim. The development of kinesthetic and kinetic hand praxis in older preschool children is a prerequisite for successful learning in school conditions. The purpose of this study is to identify the current state of neuromotor functionality  kinesthetic and kinetic hand praxis, which affects readiness for schooling, in older preschool children with speech pathology.
Material and Methods. Research methods are aimed at studying the components of neuromotor functionality: kinaesthetic and kinetic wrist praxis. To study the kinesthetic praxis of the hands, the task "Fine motility of the fingers" was used. Kinetic praxis was studied during the task "Differentiated movements of the hand". They studied the formation of object-kinetic praxis during "Performing actions with objects".
Results. The results of the experimental study give a clear idea that there are significant differences in the formation of neuromotor functionality between the groups of children with logopathology and those with normotypical psychophysical development. In older preschool children with speech disorders, low abilities were found when performing tasks of kinaesthetic and kinetic praxis: wrist (fussy movements of fingers and hands; searching for the right position, the incorrect joining of fingers, hand positions; the presence of perseveration of previous movements; underdeveloped fine motility of fingers of hands; difficulties in subject activities). Children are passive during classes, they need constant support from the teacher.
Conclusions. The revealed unformed state of neuromotor functionality confirms our hypothesis. Impairment of neuromotor function of kinesthetic and kinetic hand praxis is present in a significant percentage of preschoolers with speech disorders, which becomes a characteristic feature of this category of children and affects further physical, intellectual, and semiotic development.

Published: October 2023

Antrodia (A) cinnamomea is a precious edible and medicinal mushroom and has attracted attention because of its rare resources and unique bioactivities. The bioactive compounds from the fruit body, mycelium, and fermentation broth of A. cinnamomea include triterpenoids, polysaccharides, antroquinonols, benzenoids, and succinic and maleic acid derivatives. Among these, polysaccharides are very important and are high-content bioactive compounds. The A. cinnamomea polysaccharides (APSs) present numerous biological activities, such as antiviral, anticancer, anti-inflammatory, antivascular, immunoregulation, antioxidant, and nerve protection. However, only few studies have focused only on APSs so far. Therefore, the cultivation methods, extraction, isolation, composition, structure, biological activity, and application of APSs are summarized in this review to provide a comprehensive and convenient reference for further research and development on APSs.
Contemplation of the Body
Authors: Platovnjak Ivan
Published: October 2023

In the tradition of Christian contemplation, we find much encouragement to both contemplate nature and how we can discover God the Creator through it and how His love is imprinted on it. St Ignatius, however, in his Contemplation for the Achievement of Love, invites the praying person to contemplate not only creation, but also himself and his body. Since there is little research or literature on contemplation of the body, the author pays special attention to it in this article. He argues that the Triune God wants to reveal Himself to every man, not only through the book of nature and the Bible, but also through his body, and that contemplation of his body can be of great help to him in this. In the first chapter he briefly defines the meaning of contemplation and then turns to an understanding of the human body in the light of Scripture and spiritual theology. In the last part, he gives various examples of how we can contemplate the body and its various parts to allow the active presence and love of the Triune God to be revealed to us.

Published: October 2023

OBJECTIVES The purpose of this study is to determine whether suspension training can be an effective intervention in improving functional movement in healthy adult men.METHODS The recruited subjects of Twenty healthy adult men without musculoskeletal diseases were divided into group that performed TRX exercise (n=10) and a group that performed traditional OKC exercise using a resistance machine (n=10). The variables were the deep squat, hurdle step, inline lunge, shoulder mobility, leg raise, push-up, and rotational stability after an 8-week exercise program. The total score of the 7 movements was calculated to compare and analyze the before-and-after changes in FMS score. All the data obtained in this study were analyzed with SPSS package (ver 21.0). To examine the effects of the suspension training program used in this study, Repeated measures ANOVA was conducted to compare the effects before and after the participation in the program.RESULTS The research results are as follows; The results of the FMS evaluation scores showed no significant differences between the TRX group and the OKC group in the deep squat, hurdle step, inline lunge, shoulder mobility, leg raise, and push-up evaluations, and no interaction effect was found. However, the rotational stability evaluation score showed higher scores in the TRX group after training, showing a significant interaction effect (p<.001). The change in total evaluation score also significantly increased in the TRX group (p<.05), but there was no significant difference in the OKC group.CONCLUSIONS In conclusion, rotational stability and total evaluation scores increased after training in the TRX group. In particular, TRX training using suspension may be more effective than traditional forms of training using resistance exercise equipment for people who have instability in the multi-plane stability of the pelvis, core, and shoulder girdle, which are involved in rotational stability.
Can pre- and/or post-emergent herbicide application affect soybean seed quality?
Authors: Ceretta Jamile M. , Albrecht Alfredo J. P. , Albrecht Leandro P. , Silva André F. M. , Yokoyama Andressa Sa.
Published: October 2023

ABSTRACT Soybean cultivation requires herbicide application in the off-season, before emergence for weed desiccation, and after emergence. It is believed that the use of preand post-emergent herbicides combined with preharvest application may negatively affect the quality of soybean seeds. As such, the present study aimed to assess the effect of preand post-emergent herbicides on soybean seed quality. Five field experiments were conducted during the 2018/2019 and 2019/2020 growing seasons to investigate the effects of synthetic auxins and pre-emergents, acetyl-CoA carboxylase (ACCase) inhibitors, broadleaf herbicides, and s-metolachlor or clomazone on the quality of soybean seeds. Dicamba application combined with the pre-emergent herbicides imazethapyr/flumioxazin before soybean planting reduced seed vigor and germination. ACCase inhibitors in association with broadleaf herbicides before planting had no effect on seed quality. Applying s-metolachlor (up to 2,880 g of active ingredient [ai] ha-1) or clomazone (up to 1,800 g ai ha-1) was safe for seed germination, even when used after soybean emergence.

ABSTRACT Rice production in Brazil incurs high costs due to the significant use of agrochemicals. Some plant growth-promoting rhizobacteria (PGPR) can be used as alternative to fertilizers and phytosanitary products. Thus, the objective of this study was to characterize endophytic bacteria isolated from roots of rice plants. The isolates were characterized based on colony morphology, antibiotic resistance, carbon sources utilization, enzyme activity (catalase, amylase, protease, cellulase, and lipase), inorganic phosphate solubilization, and the 16S-23S rDNA intergenic region. Morphologically, 68% of the isolates presented a rapid growth rate, 46% presented abundant mucus production, and 77% formed viscous colonies. All isolates were resistant to nalidixic acid and 16% presented resistance to streptomycin. The majority (90%) used monosaccharides and disaccharides in carbon source assays. Most of the isolates (95%) were positive for catalase and 63.6% were positive for amylase, protease, lipase, and cellulase activities. Additionally, 59% of them were able to solubilize phosphate. The mean enzymatic index for amylase, cellulase, and protease was 2.8, 3.5, and 1.7 respectively. The similarity analysis revealed high diversity among the isolates, with similarity indices of 70% (based on morphological characteristics) and 60% (based on the intergenic region 16S-23S rDNA). Considering morphophysiological and genotypic characteristics, three promising isolates should be evaluated in studies under field conditions for the potential development of bioproducts to replace industrially manufactured inputs in rice crops.

Published: October 2023

ABSTRACT Compared to monoculture, vegetable intercropping allows the optimization of environmental resources and inputs, with positive effects on the yield and profitability of the crop. This study aimed to evaluate the yield of lettuce and arugula in intercropping and intercrop evaluation indexes according to cattle manure doses. The experiment was conducted in Aquidauana, MS, Brazil. Five doses of cattle manure (0, 15, 30, 45, and 60 t ha-1) were evaluated with four replications in a randomized block design. Higher growth and yield of the intercropped species were observed when the intercrop received 60 t ha-1 of cattle manure. However, the maximum values of the variables were not reached, so better performances can be obtained with higher doses. The indexes of actual yield loss and advantage of intercropping presented higher values starting at doses of 26 and 30 t ha-1 of manure, respectively. The highest land use efficiency (1.28) was obtained with 60 t ha-1 of cattle manure, indicating the agronomic viability of the lettuce and arugula intercrop when fertilized only with cattle manure.

ABSTRACT The area cultivated with sugarcane in Mato Grosso do Sul, Brazil, has increased significantly in recent years, in which to meet the demand of the mills, the use of adapted varieties has proved to be a fundamental strategy, combined with the use of irrigation, especially in periods of water deficit. The study aimed to evaluate the growth and yield of four sugarcane varieties (CTC 4, RB966928, RB975201, and RB92579) in plant cane cultivated with and without irrigation. The experiment was conducted at Embrapa Western Agriculture (Embrapa Agropecuária Oeste) in Dourados, MS, Brazil. A randomized block design arranged in a 2 x 4 factorial scheme with three replications was used. At 90, 150, 210, 270, 330, and 390 days after planting (DAP), stalk height and diameter, leaf area index (LAI), and dry biomass were evaluated. The soil cover percentage (%SC) was determined through aerial images taken with a drone, with evaluations made from planting to the maximum soil cover. Total recoverable sugar (TRS), number of stalks m-1, stalk (STY), and sugar (SGY) yield were evaluated at 390 DAP (harvest). The RB975201 variety has the highest growth in height, stem diameter, and LAI when grown under irrigation or without irrigation, and the CTC 4 variety has the smallest. The irrigated production system increases the growth of stalks, LAI, and degree of soil cover for the sugarcane varieties in plant cane and a greater amount of stems m-1, STY, and SGY, highlighting the varieties RB92579 and RB975201.

ABSTRACT Wastewater reuse is an alternative for irrigated agriculture in semi-arid regions, due to water support and nutritional supply. Thus, the objective was to evaluate biomass production and nutrient contents in three cultivars of Panicum maximum irrigated with fish farming effluent. The experiment was carried out in a greenhouse, with a complete randomized block design in a split-splitplot scheme. The plot consisted of three types of irrigation management (public-supply water (control), control + conventional fertilization, and irrigation with fish farming effluent). The subplot consisted of three cultivars of P. maximum (Tanzania, Mombasa, and Massai). The sub-subplot consisted of four cutting times (45, 90, 135, and 180 days after sowing). At each cutting time, biomass production and nitrogen, phosphorus, potassium, calcium, magnesium, sodium, iron, copper, manganese, and zinc contents were determined. Irrigation with fish farming effluent increases sodium content in all P. maximum cultivars and causes reduction in biomass production. The salinity of fish farming effluent increased calcium, magnesium, iron, manganese, and zinc contents in the tissues.

ABSTRACT Direct sowing is the most used watermelon propagation method in Brazil. Therefore, the use of treated seeds is an alternative for improving uniformity of plant stands at planting. Thus, the objective of this study was to assess the effects of seed treatments with biostimulant on the germination and vigor of watermelon [Citrullus lanatus (Thunb.) Matsum & Nakai] seeds of the cultivar Crimson Sweet. A completely randomized experimental design with four replications was used. The seed treatments consisted of six biostimulant (Agressive Desperta®) rates (0, 1, 2, 3, 4, and 5 mL kg-1). Seed germination speed index, seedling length, seedling dry weight, seedling emergence in the field, and seedling emergence speed index were evaluated. The treatment of watermelon seeds with biostimulant resulted in increases in seed germination speed and seedling length and dry weight as the biostimulant rate was increased. Seedling percentage and emergence speed increased up to the rate of 3 mL kg-1 under field conditions; however, application of higher rates resulted in phytotoxicity.
(In)Visible factors affecting people in the spatial appropriation process of urban green spaces in Brazil
Authors: Teixeira Carla Fernanda Barbosa , Gifford Robert
Published: October 2023

Abstract The importance of green areas in urban centers is related to the environmental quality and the sustainable development of these spaces, as well as the desirable interdisciplinary perspective. In addition to their ecological and microclimate functions, urban green spaces contribute to the establishment of a relationship between the environment and human beings, with the potential of stimulating development of sense of place. This study aims to present possible aspects involved in the process of spatial human appropriation in urban green spaces. Squares in Aracaju were the bases for observations of human behavior, which were related to spatial features. The results have revealed that, along with microclimate aspects, spatial composition, and vegetation (presence or absence), other aspects were related to the appropriation process of squares, such as decision-making based on prejudgment, exposure to risks, differentiated perceptions, and sense of vulnerability. Therefore, the qualitative, spatial, and cognitive pieces of information presented may contribute to improve the relationship between humans and environment and, consequently the appropriation of urban green spaces.

ABSTRACT This case report aimed to evaluate the swallowing capacity and the severity of the risk of laryngotracheal aspiration of a 52-year-old female patient with atypical and rare stroke, with major injury in the cerebellar pathway. In order to measure swallowing capacity and risk of aspiration a routine clinical assessment used in the speech therapy clinic was performed and two valid clinical tests were used: Massey Bedside Swallowing Screen (MBSS) and Gugging Swallowing Screen (GUSS). After evaluation with the clinical tests, it was observed that the patient had reduced swallowing capacity, performance characterized as pathological, 100% dysfunction in the water swallowing test (MBSS), presence of choking, coughing, change in vocal quality and anterior escape. In the assessment of risk of aspiration with the GUSS, the patient presented moderate dysphagia and risk of laryngotracheal aspiration.This case report demonstrated that moderate dysphagia is found in a stroke patient with lesions that affect the cerebellum. Standardized and validated clinical tests such as GUSS and MBSS should also be used to assess the risk of dysphagia after stroke at ambulatory care.

The article presents and discusses the scope of Worker’s Health (WH) actions in PHC in São Paulo. Within the context of a thematic project, an interview and two focus groups were carried out with professionals working in a Basic Unit in the northern region of the city in 2019. The resulting material was assessed using thematic content analysis. The private outcontracting of part of the public services management, the decay of labor rights and agendas related to worker’s health, the overload of the PHC teams that started to develop actions of different lines of care, in addition to the quantitative issue and the territorial scope of the WH Reference Center (CEREST) are obstacles to the conformation and consolidation of WH practices in PHC. There is a challenge in resizing services and requalifying actions, considering the interfaces production-work-health.

An experimental investigation of a small-scale air-heated humidification–dehumidification (HDH) desalination system with bubble-column humidification and dehumidification units was conducted. The study addressed the performance of the multistage air-heated bubble-column HDH system, which has limited coverage in the literature, by operating two bubble-column humidifiers in series for the air humidification process with air reheating. The effect of operating parameters such as airflow rate, air temperature, and saline water levels in both humidifiers on the performance metrics of the system were investigated. The product distillate rate, energy consumption, gain output ratio (GOR), and specific energy consumption (SEC) are the main indicators of performance for the proposed desalination system. Response surface methodology (RSM) was applied to the current system using the design of experiment (DoE) for the prediction of variables that greatlyaffect productivity and energy input. The airflow rate, air temperature, and water level of the second humidifier have a favourable effect on the distillate rate and GOR of the system. In contrast, the effect of the water level inside the first humidifier is insignificant. Furthermore, the RSM optimization approach was used to obtain the optimum distillate productivity. An optimized distillate rate of 0.45 L/h and a GOR of 0.4 are achieved at 1.5 SCFM (standard cubic feet per minute) of airflow rate, and 6.5 cm of water level in the second humidifier with 140°C air inlet temperature. The numerical optimization reveals the optimal operating parameters, that correspond to maximum distillate production of 0.3 L/h with minimum input energy of 0.71 kW, to be 139°C air temperature, 1.13 SCFM of airflow rate, 6.5 cm and 3 cm water levels of second and first humidifier, respectively.

Authors: SHERDANOV Ch.T. , ILYASOV S.P.
Published: October 2023

Based on synoptic maps, the orientation and localization (distribution) of coronal bright points (CBP) relative to the polarity line (PL) on the Sun is studied. Preliminary results show that the slope of the CBP angles of the quiet Sun is oriented, in most cases, parallel to the solar equator, while for the CBP of the active Sun it is more randomly distributed. The question of the localization of both types of CBP with respect to active formations and PL is not so clear and requires a more detailed study.

Authors: Поливанова Катерина
Published: October 2023

Монография посвящена описанию современных практик материнства, их обсуждению в общественном поле и новым проблемам родительства. Трансформация семьи, ориентация современных матерей на научное знание на фоне критического отношения к традиционным прародительским практикам воспитания детей — все это меняет современные семейные практики и уклад. Семья все больше берет на себя роль заказчика образования, что обусловливает особую заинтересованность матерей в выстраивании образовательной траектории детей начиная с первых дней в школе и в семейном образовании, в проектировании образовательных проб в рамках дополнительного образования. Новая конфигурация семейных практик и представлений о собственном родительстве провоцирует стремление к самообразованию, что формирует запрос на программы для родителей, который удовлетворяется преимущественно через просвещение. В настоящей книге акцент делается на развитие родительской самоэффективности. Издание предназначено для широкого круга читателей, аналитиков и исследователей сферы образования и детской психологии, педагогов и родителей.
Cannabis use: A look at different factors and a reflection on its susceptibility to work-related accidents
Authors: Francois GD Beaulieu , Mahée Coté
Published: October 2023

Misinformation and popular beliefs on cannabis use have had an impact on the Canadian population. The trivialization of the substance and poor understanding of its side effects tend to add to the risks of work-related environments that already require acute senses and sharp attention. In this research project, we aim to observe different concurrent factors of cannabis use in Canada and how it articulates with the rising rates of work-related accidents. Since recreational cannabis use has been legalized, and with the onset of the COVID-19 pandemic, more people appear to be consuming and/or appear to have increased their usage. We will take a closer look at the impact of these factors, the role that misinformation plays on cannabis use, and how we can contribute towards healthier and safer working environments in Canada.

In India, utilization of construction & demolition (C&D) waste-based coarse recycled concrete aggregate (CRCA) for RCC work is limited up to 20% for M25 grade of concrete as codified in IS 383:2016. However, enhanced utilization is not possible until classification based on quality grading of C&D waste-based aggregate is made available. One of the possible ways to classify C&D waste-based aggregate can be routed based on specific gravity and water absorption value of the parent rock which is generally affected by the adhered mortar. In the present study, C&D waste-based coarse recycled concrete aggregate (CRCA) sourced from two different sources was studied holistically. CRCA aggregates were subjected to mechanical treatment in a Los Angeles machine and Characteristics of CRCA before and after treatment were evaluated and compared. Further, a comparative study in fresh, hardened, and durability stages was conducted on the properties of concrete made with treated and non–treated CRCA. Fresh, hardened, and durability properties of concrete made with C&DW-based CRCA investigated for the (a) Fresh properties – workability in terms of slump, and air content. (b) Hardened properties–compressive and flexural strength, modulus of elasticity, drying shrinkage (c) Durability properties –resistance to chloride (RCPT, as per ASTM C1202), resistance to carbonation as per ISO 1920 Part 12 and resistance to water penetration as per IS 516 Part2 / Section-1. From the study, it can be concluded that physical properties such as specific gravity and water absorption of CRCA can be used as a tool for the grading of C&D waste-based CRCA. Based upon fresh, hardened, and durable behavior of concrete made with CRCA, it was observed that non-treated CRCA can be used up to 40 % for a grade of concrete up to M 30 whereas treated CRCA can be used up to 100 %. This was attributed to the improvement in the ITZ.
