Patient recruitment in the US includes a variety of services—typically performed by a Patient Recruitment Service Provider—to increase enrollment into clinical trials. Presently, the patient recruitment industry is claimed to total $19 billion [1] per year. [2] Patient enrollment is the most time-consuming aspect of the clinical trial process.
In the K–12 classroom, learning standards do not commonly address the affective domain due to the difficulty in developing teaching strategies and in assessing student attitude. Many modern teaching strategies have been shown to have positive impacts on student attitudes toward science including the use of student-centered instruction ...
Chemistry education (or chemical education) is the study of teaching and learning chemistry. It is one subset of STEM education or discipline-based education research (DBER). [1] Topics in chemistry education include understanding how students learn chemistry and determining the most efficient methods to teach chemistry.
Gravimetric analysis describes a set of methods used in analytical chemistry for the quantitative determination of an analyte (the ion being analyzed) based on its mass. The principle of this type of analysis is that once an ion's mass has been determined as a unique compound, that known measurement can then be used to determine the same analyte's mass in a mixture, as long as the relative ...

Chemistry Education Research and Practice is a quarterly peer-reviewed open access academic journal published by the Royal Society of Chemistry covering chemistry education. The editor-in-chief is Gwen Lawrie of the University of Queensland .
Basic research advances fundamental knowledge about the world. It focuses on creating and refuting or supporting theories that explain observed phenomena. Pure research is the source of most new scientific ideas and ways of thinking about the world. It can be exploratory, descriptive, or explanatory; however, explanatory research is the most ...
The primordial soup theory of the origin of life, proposed by Alexander Oparin in Russian in 1924 (published in English in 1936) [9] and by J.B.S. Haldane in 1929, [10] suggested that life was preceded by the formation of what Haldane called a "hot dilute soup" of "colloidal organic substances", and which Oparin referred to as 'coacervates ...
