This course covers the following questions. What are the predominant heat producing elements of the Earth? Where and how much are they? Are they present in the core of the Earth? Detection of antineutrinos generated in the Earth provides: 1) information on the sources of the terrestrial heat, 2) direct test of the Bulk Silicate Earth (BSE) model and 3) testing of non-conventional models of Earth’s core. Use of antineutrinos to probe the deep interior of our planet is becoming practical due to recent fundamental advances in the antineutrino detectors.
The Basics of General, Organic, and Biological Chemistry by David W. Ball, …
The Basics of General, Organic, and Biological Chemistry by David W. Ball, John W. Hill, and Rhonda J. Scott is the right text for you and your students if you are looking for a GOB textbook with just the right amount of coverage without overdoing the concepts and overwhelming your students. These experienced authors have ensured their text has ample in-text examples, and “Test Yourself“ questions following the examples so students can immediately check their comprehension. The end-of-chapter exercises will be paired, with one answered in the back of the text so homework can easily be assigned and self-checked

In the master-equation formalism, a set of differential equations describe the time-evolution of the probability distribution of an ensemble of systems. This can be used, for example, to describe the varied mRNA copy numbers found in individual cells in a population.

The stochastic simulation algorithm (SSA, Kinetic Monte Carlo, Gillespie algorithm) produces an example trajectory for a particular member of a probabilistic ensemble by looping over the following steps. The current state of the system is used to determine the likelihood of each possible chemical reaction in relative comparison to the likelihoods for the other possible reactions, as well as to determine when the next reaction is expected. Pseudo-random numbers are drawn to "roll the dice" to determine exactly when the next reaction will proceed, and which kind of reaction it will happen to be.

This is an Excel spreadsheet and graph that illustrates standard "batch" and Rayleigh decarbonation models and how they can be used to detect fluid infiltration during metamorphism of carbonates. It makes a good lecture demonstration, but with a few modifications can be turned into a laboratory exercise. Key variables are "hotlinked" directly into the batch and Rayleigh models so students can adjust them to get a feel for the influence of different model parameters. The included carbon isotope data are from marbles in the Jervois region, central Australia (Cartwright et al., 1997). Oxygen isotope data are also included in the spreadsheet.

These Pre-Chemistry online modules are designed to function as chemistry preparation for first year chemistry students. It is particularly useful for students who, for various reasons, are otherwise not confident in their preparation for first year university level chemistry. However, the module can be used as a practical and valuable review for all students. The module focuses on the development of fundamental numeracy and problem solving skills that are widely applicable to students in a variety of first year chemistry courses including those directed to students in life science, engineering and natural and physical sciences. These modules function effectively in both online, hybrid or even as preparation for entirely traditionally delivered courses.

The PhET project at the University of Colorado creates "fun, interactive, research-based simulations of physical phenomena." This particular one deals with Beer's Law. "The thicker the glass, the darker the brew, the less the light that passes through." Make colorful concentrated and dilute solutions and explore how much light they absorb and transmit using a virtual spectrophotometer! The simulation is also paired with a teachers' guide and related resources from PhET. The simulation is also available in multiple languages.

This text introductory chemistry text is aimed for a single semester or quarter beginning experience to the field. The textmaps survey some of the basic topics of chemistry. This survey should give student enough knowledge to appreciate the impact of chemistry in everyday life and, if necessary, prepare student for additional instruction in chemistry.

When 1,2-diketones ( α-diketones) on treatment with alcoholic KOH to give alpha- hydroxy acid. This is intramolecular base catalyased reaction. This is called as pi molecular rearrangement with second order rate reaction. In this rearrangement migrating group migrates towards electron deficient carbon atom.In this rearrangement Less eletron releasing group migrates first.

It is an interactive illustration about the Bhopal Gas Tragedy. It covers when and where did the incident occur, the company where this incident occured, the gas leaked and about the negligience of the officials, the cause of the incident and the learning outcomes, the company (and people) resposible for the tragedy, the series of events that occured and the affected areas and the lives affected by the Bhopal Gas Tragedy. It was made using the Mindomo app.

In this activity students work through a binary eutectic phase diagram in small groups and try to determine a set of generalizations that explain the behavior of such systems (e.g., "the first liquid produced upon heating is always the eutectic composition").
