Technology Gap Theory is a model developed by M.V. Posner in 1961, which describes an advantage enjoyed by the country that introduces new goods in a market. [1] The country will enjoy a comparative advantage as well as a temporary state of monopoly until other countries have achieved the ability to imitate the new good.
A science project is an educational activity for students involving experiments or construction of models in one of the science disciplines. Students may present their science project at a science fair, so they may also call it a science fair project. Science projects may be classified into four main types.
An electronic lab notebook (also known as electronic laboratory notebook, or ELN) is a computer program designed to replace paper laboratory notebooks. Lab notebooks in general are used by scientists , engineers , and technicians to document research , experiments , and procedures performed in a laboratory.
An inventor's notebook is used by inventors, scientists and engineers to record their ideas, invention process, experimental tests and results and observations. It is not a legal document but is valuable, if properly organized and maintained, since it can help establish dates of conception and reduction to practice .
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research. Researchers use a lab notebook to document their hypotheses, experiments and initial analysis or interpretation of these
The difference between the two peak potentials (E p), ΔE p, is of particular interest. ΔE p = E pa - E pc > 0. This difference mainly results from the effects of analyte diffusion rates. In the ideal case of a reversible 1e- couple (i.e., Nernstian), ΔE p is 57 mV and the full-width half-max of the forward scan peak is 59 mV. Typical values ...
Thus the membrane potential will not be right at E K, but rather depolarized from E K by an amount of approximately 5% of the 140 mV difference between E K and E Na. Thus, the cell's resting potential will be about −73 mV. In a more formal notation, the membrane potential is the weighted average of each contributing ion's equilibrium ...
This hinders the use of the MPV reduction on scale. Aluminium alkoxides made in situ from trimethyl aluminium reagents have far better activity requiring as little as 10% loading. The activity difference is believed to be due to the large aggregation state of the commercially available product. [11] Several side reactions are known to occur.
