When education, and especially higher education, is considered as a public social right that everyone should have access to, human capital, as solely informed by the investment approach, cannot be seen as the most appropriate tool to explain the benefits an individual and society can gain from ...
A study in Mexico found that respiratory epidemics may explain up to 50% of heat-related excess deaths in Monterrey during days 95 °F (35 °C) and above (O'Neill et al., 2005a). While these physiological conditions are the primary drivers of sensitivity, environmental factors are known ...
The permeation of water in polyurethane foam is divided into the permeation of closed-cell and open-cell structures. The permeation of the open-cell structure belongs to the seepage of porous media, and the permeation equation usually adopts Darcy's law [61]and the extended Darcy's law [62...
State and explain the law of definite proportions. Define cloud and pour points and state their importance. Why is the law of definite composition important? What is the major premise of Hess's Law? Explain Hund's rules. For Hund's rule, we often find that its applicability bec...
Sophia thinks that kettle1 will take a shorter time to heat the water up to 100°C. She finds that both kettles take the same time to reach 100° C. Explain why the kettles take the same time to heat the water up to 100° C. ...
End-of-life management for marine structures demands exceptionally sustainability practices due to the potential for environmental and health hazards associated. The purpose of this article is to explain how improved recycling, reusing, and disposal techniques contribute to the marine industry's long-term...
In Section 2, we introduce the thermal model of a city bus cabin and its HVAC system. We explain how we quantify thermal comfort, introduce the disturbances and their data sources, and introduce the steady-state approximation of the model. In Section 3, we formulate the optimization problem ...
