kant’s ethical theory is one the most important theories in philosophy of ethics, which has always attracted the attention of the commentators and critics. although it has many positive points, there are some objections to this theory just as to any other human theory. in this article, it is attempted to point out the critiques that seem to have been leveled against kant’s ethics. some of these...

Evolution of one-dimensional electron system under high-energy-density (HED) conditions is investigated, using the principle of least-action and variational method. In a single-mode modulation model, the amplitude and spatial wavelength of the modulation are chosen to be general coordinates. Equations of motion are derived by considering energy conservation and force balance. Numerical results ...

The precautionary principle was included in 1992 in the Rio Declaration on Environmental and Development and is a part of important international agreements and documents, for example, the Convention on Biological Diversity. Yet the interpretation of this principle is not straightforward as a guide for environmental policy – a variety of interpretations are possible. This paper identifies and e...

physiologically thermal comfort condition is a limit of temperature and humidity. ,in which thermal control mechanism of human body is in its least activity . thermal comfort conditions not only have impact on sizes of heating and cooling equipment ,but also affects the thickness of insulation, and .energy, consumption of buildings. it is necessary to define thermal comfort condition for differ...

Abstract Elastodynamic equations have been formulated with Newton's second law of motion, Lagrange's equation, or Hamilton's principle for over 150 years. In this work, contrary to classical continuum mechanics, a novel strategic methodology is proposed formulating general mechanical using the energy conservation. First, based on principle, equations, and elastodynamic equation motion are deriv...

abstract in order to assess the environmental impact of agricultural activity, the long-term sustainability should be considered. in order to achieve solutions to reduce energy consumption and carbon emissions in the production of rainfed sunflower, this assessment was conducted in the north east of iran. four production methods, i.e. conventional tillage (ct), tow reduced tillages (rt1and rt2)...
