Sunblock shields the skin from harmful Ultraviolet (UV) rays. These rays, emitted by sun, pose various health risks, particularly to skin. UV exposure can lead premature aging, melasma, melanoma, and other ailments. Therefore, applying sunscreen is vital in safeguarding preventing UV-induced diseases. Correct application of crucial ensure its effectiveness. This research aims establish correlat...
In the present study, we explore the analyses of coping strategy for IT digital divide on the elementary campus. The questionnaire was distributed by stratified random sampling. The cases included 39 schools and 150 teachers. The study adopted the questionnaire of “SWOT Strategic Analysis for Digital Divide” to investigate the digital learning environment on campus and to understand teachers’ o...
Modern visual arts education enables student’s permanent creative expression, while art appreciation plays an equally important role. This article presents the results of a study that monitored the level of art appreciation abilities of 10-year-old primary school students from north-eastern Slovenia utilizing a sample of 1,429 students (n=1,429). The study explored whether there are differences...
Mechanical shields can effectively alleviate the problems of low pesticide utilization and severe environmental pollution. This manuscript uses a computational fluid dynamics (CFD) method to investigate anti-drift mechanism mechanical shields, study airflow forms around them, establish an accurate simulation model. The aerodynamic characteristics six were studied, their effect was compared. The...
[1] Small volcanic edifices, shields with a diameter less than about 20 km, are common and sometimes very abundant features on the plains of Venus. Typically, they form tight or loose clusters of features known as shield fields. Small shields are interpreted to be formed due to small-scale eruptions through numerous and distinct sources, a mode of formation apparently significantly different fr...
Rubble mound near-bed structures are among the more common hydraulic structures. Examples include bottom protections to prevent scour near bridge piers, offshore structures, weirs and sluices and at the toe of bank protections or breakwaters, but also pipe covers on offshore pipelines. The cornerstone of the theory behind the design of these structures was laid by Izbash (1930) and, most notabl...
