The main purpose of this study is to investigate the effects of effective use of sunlight on building forms by using existing developable techniques in parallel with the methods that can be renewed, resorting to control systems related to smart lighting in schools, and to examine the performance of the methods that maximize the competent use of the sun's rays in this regard in terms of system conditions that direct the sun's rays. Using daylight effectively by using intelligent lighting control systems in schools is a common area related to many strategies, especially energy conservation. The efficient use of daylight in schools ensures the efficient use of energy at the same time. The effective use of daylight in schools depends on the effective use of economical and natural lighting systems in parallel with the developing technology. This situation also appears as a mechanism that develops in direct proportion to the rate of progress of increasing technologies related to systems that direct sunlight.

This study aims to examine the performance levels of the methods that maximize the effective use of daylight by using intelligent lighting control systems in schools. As is known, in general, daylight is an indispensable element of the ecological cycle as a natural light source. The concept of daylight with people and structures within the framework of the study and the relationship of these formal functions, with an emphasis on the effective use of intelligent lighting control systems in schools and the use of light to enhance the performance of the methods by raising a clearer grasp and use in the field to add to the evolving system of methods and principles were elaborated. In this formal integrity, the benefits and requirements of these system functions have been emphasized by approaching the issue from the point of view of the system that carries daylight in schools with these intelligent lighting control systems.

Karakashev, Stoyan/0000-0003-2921-6596 ; WOS:000557984300001 ; In this study, the critical coalescence concentrations (CCC) of selected commercial frother solutions, namely polypropylene glycols (PPG 200, 400, and 600), tri propylene glycol (BTPG), triethylene glycol (BTEG), dipropylene glycol (BDPG), and as a reference, methyl isobutyl carbinol (MIBC), were determined using a bubble column based on light absorption. The results for all seven frothers showed that BTEG has the worst bubble inhibiting performance, and PPG 600 has the best bubble inhibiting performance. While critical coalescence concentration (CCC) was found as 3 ppm for PPG 600, it increased to 25 ppm for BTEG. In the case of MIBC, which was the reference point, the CCC value was found as 10 ppm, which was consistent with the literature. The surface tension isotherms of the frothers were determined and analyzed with one of the latest adsorption models. The results indicated that the polypropylene glycol frothers showed more surface activity compared to alcohol or other frothers investigated. This is due to the additional reorganization of the PPG molecules on the air/water interface, thus boosting its surface activity. ; EUROPEAN UNION'S HORIZON 2020 [821265] ; This research and the APC were funded by EUROPEAN UNION'S HORIZON 2020, grant number 821265.
