More broadly, the idea of green chemistry can easily be linked (or confused) with related concepts like green engineering, environmental design, or sustainability in general. Green chemistry's complexity and multifaceted nature makes it difficult to devise clear and simple metrics. As a result, "what is green" is often open to debate. [42]
She stated in her nursing notes that nursing "is an act of utilizing the environment of the patient to assist him in his recovery" (Nightingale 1860/1969), [2] that it involves the nurse's initiative to configure environmental settings appropriate for the gradual restoration of the patient's health, and that external factors associated with the patient's surroundings affect life or biologic ...
The Helvie Energy Theory of Nursing and Health is a nursing theory developed by Carl O. Helvie's lifelong cross-cultural exposure to various ways of assessing, planning, implementing and evaluating health with application to individuals, families, and to specific communities across the world.

Carl O. Helvie (August 13, 1932 – December 3, 2019) [1] was an American registered nurse and Professor Emeritus of Nursing at Old Dominion University.Helvie is known for his development and implementation of the Helvie Energy Theory of Nursing and Health.
The conservation model of nursing is based around the law of conservation of energy, combined with the psycho-social aspects of the individual's needs. Levine believed that these needs are joined within the individual as a "cascade of life events, churning and changing as the environmental challenge is confronted and resolved in each individual ...
Green solvents are environmentally friendly chemical solvents that are used as a part of green chemistry. They came to prominence in 2015, when the UN defined a new sustainability -focused development plan based on 17 sustainable development goals, recognizing the need for green chemistry and green solvents for a more sustainable future.

Environmental chemists draw on a range of concepts from chemistry and various environmental sciences to assist in their study of what is happening to a chemical species in the environment. Important general concepts from chemistry include understanding chemical reactions and equations, solutions, units, sampling, and analytical techniques. [1]
Atom economy is an important concept of green chemistry philosophy, [2] [3] [4] and one of the most widely used metrics for measuring the "greenness" of a process or synthesis. Good atom economy means most of the atoms of the reactants are incorporated in the desired products and only small amounts of unwanted byproducts are formed, reducing ...
