Measuring students' conceptual understandings has become increasingly important to biology faculty members involved in evaluating and improving departmental programs. We developed the Molecular Biology Capstone Assessment (MBCA) to gauge comprehension of fundamental concepts in molecular and cell biology and the ability to apply these concepts in novel scenarios. Targeted at graduating students...

The principle of equipartition of (kinetic) energy for all-atom Cartesian molecular dynamics states that each momentum phase space coordinate on the average has ½kT of kinetic energy in a canonical ensemble. This principle is used in molecular dynamics simulations to initialize velocities, and to calculate statistical properties such as entropy. Internal coordinate molecular dynamics (ICMD) mod...

Using the Molecular Dynamics technique the energy E vs the misorientation 9 has been calculated for the CSL [OOl] twist grain boundaries in Cu. Two potentials have been used; the Morse potential and a spline potential constructed by Englert and Tompa for Cu. In each case the low and high angle grain boundary regions have been clearly distinguished by using the relation E= Eo9(A-he), valid for l...

We present the first results obtained with a Hybrid Molecular Dynamics algorithm applied to an N = 1 SU(2) Super-Yang–Mills on the lattice. We derive the Hamilton equations of motion for the system with Wilson gluinos and present preliminary results on small lattices.

Molecular epidemiology refers to the incorporation of molecular techniques in epidemiological studies. There are different biomarkers in cancer research used for molecular epidemiology including markers of exposure, markers of dose, susceptibility, treatment response, prognosis, altered structure/function and cancer type. Selected markers, especially those of exposure and susceptibility, are de...

Flotation is the single most important method of mineral processing and is widely used for the concentration of metal ores, industrial minerals, and coals. Several investigations were carried out during the last century, and the flotation literature was immense, particularly on selective collectors and their interaction mechanisms on sulfide, oxide, and silicate minerals. However, it is often d...
