The present article provides a substantiation of the need to use the potential of the philosophy of science in designing a sustainable development project. Along with mathematics and informatics, the philosophy of science is viewed as an auxiliary science designed to help clarify the conceptual and methodological nature of scientific theories. New provisions of science philosophy are presented. The proposition that all axiological theories culminate in ethics is proved. It is also substantiated that natural sciences demonstrate ethical relativity. The project, i.e. both the concept and conception (theory) of sustainable development was designed with no consideration of the achievements of science philosophy including scientific ethics. As the project developed its content became not clearer but, on the contrary, more obscured. The project of sustainable development is reevaluated in light of the philosophy of science. It turns out to be nothing more than a paraphrase of the need for...

This paper focuses on creating a Water Refiling Station Management System (WRSMS) for selected water refilling stations in Havana, Cuba as most of them still operate by means of pen and paper, a tedious as well as time-consuming process when it comes to recording, manipulating, editing, and retrieving data, which leaves room for errors. The WRSMS is capable of storing, processing, and monitoring sales, customer, employee, inventory and attendance data, which it can be used to create financial statement reports. Furthermore, expressive investigation technique is used in this paper to assess current system of selected water stations and the WRSMS in terms of functionality and usability. It also helped to determine the noteworthy alteration among current system and WRSMS assessment. The researcher used purposive sampling technique and an industry-validated instrument to assess functionality and usability of employees from selected water stations in the area and was able to get the part...

espanolLa luz del dia es una de las fuentes de luz mas importantes que podria iluminar los espacios interiores al pasar a traves de ventanas y colectores de luz. La acumulacion de polvo y aerosoles en los cristales de las ventanas reduce la cantidad de luz que pasa a traves de ellos. El objetivo principal de esta investigacion es determinar el impacto de la deposicion de particulas en el aire sobre la cantidad de luz pasada. En este experimento, se obtuvieron las particulas mas prevalentes, como el polvo, el carbono y una mezcla de ambos examinados con vidrios comerciales comunes de 3 mm en cristales de vidrios simples y dobles y se obtuvieron varias observaciones interesantes. El resultado de este experimento ayudara a los propietarios de edificios a ajustar un programa de limpieza de ventanas para reducir el consumo y los gastos de electricidad de iluminacion. EnglishDaylight is one of the most significant light source which could illuminate interior spaces by passing through wind...

En este trabajo se estudió la cinética de secado de la levadura cervecera tomando en consideración el fenómeno de encogimiento presentado por la misma. Los datos experimentales se obtuvieron a tres temperaturas diferentes. Se evaluó el encogimiento volumétrico y de grosor de la levadura por medición directa determinada durante el secado. Se encontró que el encogimiento de la levadura es casi isotrópico e incide significativamente en la velocidad de secado. Además, la levadura durante el secado presenta solamente un periodo de velocidad decreciente y no exhibe curva característica de secado.
