Weak sustainability is an idea within environmental economics which states that ' human capital ' can substitute ' natural capital '. It is based upon the work of Nobel laureate Robert Solow, [1] [2] [3] and John Hartwick. [4] [5] [6] Contrary to weak sustainability, strong sustainability assumes that 'human capital' and 'natural capital' are ...
t. e. In particle physics, the electroweak interaction or electroweak force is the unified description of two of the four known fundamental interactions of nature: electromagnetism (electromagnetic interaction) and the weak interaction. Although these two forces appear very different at everyday low energies, the theory models them as two ...
NOvA. v. t. e. Grand Unified Theory ( GUT) is any model in particle physics that merges the electromagnetic, weak, and strong forces (the three gauge interactions of the Standard Model) into a single force at high energies. Although this unified force has not been directly observed, many GUT models theorize its existence.
A matrix organization. Matrix management is an organizational structure in which some individuals report to more than one supervisor or leader—relationships described as solid line or dotted line reporting. More broadly, it may also describe the management of cross-functional, cross-business groups and other work models that do not maintain ...
B − L. −1. X. −3. A neutrino ( / njuːˈtriːnoʊ / new-TREE-noh; denoted by the Greek letter ν) is a fermion (an elementary particle with spin of 1 2) that interacts only via the weak interaction and gravity. [2] [3] The neutrino is so named because it is electrically neutral and because its rest mass is so small ( -ino) that it was ...
Biomagnetism is the phenomenon of magnetic fields produced by living organisms; it is a subset of bioelectromagnetism. In contrast, organisms' use of magnetism in navigation is magnetoception and the study of the magnetic fields' effects on organisms is magnetobiology. (The word biomagnetism has also been used loosely to include magnetobiology ...
In the early 1990s, Carolyn M. Dry created the first modern contemporary self-healing approach by developing a configuration that facilitates the release of repair chemicals from fibers embedded in a cementitious matrix. Since then, research community has developed various techniques to incorporate self-healing properties in the concrete.
Positronic brain. A positronic brain is a fictional technological device, originally conceived by science fiction writer Isaac Asimov. [1] [2] It functions as a central processing unit (CPU) for robots, and, in some unspecified way, provides them with a form of consciousness recognizable to humans. When Asimov wrote his first robot stories in ...
