SYNTHESIS OF BIODIESEL: A CONTEXTUALIZED EXPERIMENT PROPOSAL FOR THE GENERAL CHEMISTRY LABORATORY. The contextualized understanding of concepts in Chemistry by students from other areas is a challenging task. In this experiment, the synthesis of biodiesel is done by base catalyzed transesterification of refined soy oil with methanol at room temperature and common glassware found in any chemistr...
متن کاملProtein Foldability and Designability: General Physics and Pretty Chemistry
Making use of a simplified model for protein folding, it can be shown that conformations which are particularly stable when their energy is minimized with respect to amino acid sequence (in the sense that they display a large energy gap to the lowest structrally dissimilar conformation), aside from leading to fast folding, are highly designable (in the sense that many sequences target onto it i...
متن کاملFirst 25-hydroxyvitamin D assay for general chemistry analyzers.
25-Hydroxyvitamin D [25(OH)D], the predominant circulating form of vitamin D, is an accurate indicator of the general vitamin D status of an individual. Because vitamin D deficiencies have been linked to several pathologies (including osteoporosis and rickets), accurate monitoring of 25(OH)D levels is becoming increasingly important in clinical settings. Current 25(OH)D assays are either chroma...
متن کاملUsing home-laboratory kits to teach general chemistry
University-level chemistry courses that contain a substantial laboratory component have always been a challenge to deliver effectively through distance education. One potential solution is to enable students to carry out real experiments in the home environment. This not only raises issues of logistics and safety, but also the fundamental question of whether an equivalent learning experience co...
متن کاملBipolar general fuzzy automata
In this paper, we define the notion of a bipolar general fuzzy automaton, then we construct some closure operators on the set of states of a bipolar general fuzzy automaton. Also, we construct some topologies on the set of states of a bipolar general fuzzy automaton. Then we obtain some relationships between them.
