Water purification using adsorption is a crucial process for maintaining human life and preserving the environment. Batch and dynamic adsorption modes are two types of water purification processes that are commonly used in various countries due to their simplicity and feasibility on an industrial scale. However, it is important to understand the advantages and limitations of these two adsorption modes in industrial applications. Also, the possibility of using batch mode in industrial scale was scrutinized, along with the necessity of using dynamic mode in such applications...

Using a variant of the hide-and-seek game, we show in three studies that self-enhancement can help or hinder strategic thinking. In this guessing game, one player chooses a number while another player tries to guess it. Each player does this either in a random fashion (throwing a mental die) or by active thinking. The structure of the game implies that guessers benefit from thinking about a number, whereas choosers are disadvantaged. Yet, regardless of their role, respondents prefer to actively think about a number...

Movement systems are massively redundant, and there are always multiple movement solutions to any task demand; motor abundance. Movement consequently exhibits 'repetition without repetition', where movement outcomes are preserved but the kinematic details of the movement vary across repetitions. The uncontrolled manifold (UCM) concept is one of several methods that analyses movement variability with respect to task goals, to quantify repetition without repetition and test hypotheses about the control architecture producing a given abundant response to a task demand...

CONTEXT: Baseball pitching requires fast and coordinated motions of the whole body to reach high ball speeds, putting considerable strain on the musculoskeletal system, particularly the shoulder and elbow. DESIGN: Descriptive epidemiology study. OBJECTIVE: To describe musculoskeletal symptoms and the functional status of the shoulder and elbow in male high school baseball pitchers. SETTING: Dutch baseball talent academies...

The objective of this study was to examine the psychometric properties of the Pictorial Scale of Perceived Movement Skill Competence (PMSC) for young Norwegian children, a scale that is aligned with skills assessed in the Test of Gross Motor Development- Third Edition. We used convenience sampling to recruit 396 Norwegian-speaking children (7-10-year-olds) who completed the PMSC. A confirmatory factor analysis (CFA) confirmed factorial validity for the proposed three-factor model of the PMSC, encompassing measures of self-perceived ball, locomotor, and active play competence...

OBJECTIVE: The present study probes into the association between children's fundamental movement skills (FMS) and moderate-to-vigorous physical activity (MVPA) during weekdays and weekends. METHODS: This cross-sectional sample included 1014 children aged 6-10 years from the REACT project. Physical activity was assessed with accelerometry, and five FMS (stationary dribble, kick, catch, overhand throw, and underhand roll) were assessed with the digital platform Meu Educativo®...

Shoulder injuries are common in baseball pitchers and primarily involve the glenohumeral joint. Past analyses have examined shoulder biomechanics during different pitch types simply as the motion of the upper arm relative to the thorax. In this study, glenohumeral and scapulothoracic kinematics were compared between fastballs and curveballs at key timepoints throughout a pitch. Upper extremity kinematics of thirteen collegiate pitchers were collected during fastball and curveball pitches with motion capture...

Objectives : The objective is to compare stiffness changes around the shoulder muscles between pitchers and position players after throwing overhead using shear wave elastography (SWE) in relation to throwing motion analysis and muscle strength. Methods : A total of 32 male college baseball players (12 pitchers and 20 position players) were observed throwing 20 times, and SWE was performed to evaluate 13 shoulder muscle items-tendons (supraspinatus, infraspinatus, subscapularis, and teres minor), muscles (supraspinatus, infraspinatus [transverse and oblique part], teres minor, lower trapezius, latissimus dorsi, and pectoralis minor), and capsules (posterior and posteroinferior)...

Water polo players' shoulders are exposed to repeated overhead and throwing motions as well as direct and indirect traumas. Shoulder injuries account for over half of all injuries sustained by water polo players. This is a monocentric descriptive epidemiological study on the clinical and radiological presentation of a consecutive series of water polo players from January 2002 to September 2022. All patients underwent clinical and physical examinations and an MRI arthrogram. A total of 92 water polo players were included in this study...

Exercise training integrating physical and cognitive activities is gaining attention because of its potential benefits for brain health. This study focuses on exercise training using a dart game called Wellness Darts. Wellness Darts is a sport involving throwing darts and walking to pull them out of the board, memorizing the score, and subtracting this from the total score, thus requiring the simultaneous performance of two tasks: exercise and calculation. This is expected to maintain and improve cognitive function, and whether this continual darts training affects brain function is of great interest...

INTRODUCTION: Vitriolage or acid attack or acid throwing is a gender-based terrible violent crime. There are many everlasting sequels of vitriolage which consist of permanent scarring of the face or body, blindness as well as socioeconomic and psychological intricacy. The sufferer of acid attack is competitor, hatred, enmity or jealousy. Vitriolage are most common in the Asian countries especially in south east Asian region followed by Europe and South America. Bangladesh, India, Pakistan, Colombia and Cambodia are the countries having the highest incidence of acid attacks...

In this article, we turn back to the 1918 influenza pandemic to throw light on the alliances of information communication technologies and technologies of mobility (such as the car) during the pandemic. We examine newspaper articles, technical publications, and other historical texts to demonstrate that, despite the fact that mobile technologies-such as cellular phones-did not exist during the 1918 pandemic, the telephone and mobility technology nonetheless formed alliances as networks in motion, or social moments in which risk and reward are calculated not simply by the ability to move, but rather the ability to move, while remaining connected, revealing insight into early cultural formations that share similarities and differences with the use of modern mobile media and mobility technologies during the ongoing COVID-19 pandemic...

How might concepts of 'value' and 'population' illuminate the present and future of urban density? The COVID-19 pandemic prompted a public debate on density in the city. While some initially blamed density for the spread of the virus, others rightly cautioned against those claims. As the pandemic progressed, an imaginary of density-as-pathology gave way to a more nuanced geographical understanding of the urban dimensions of the crisis, focused on connections, spatial conditions, domestic 'overcrowding' and poverty...
