Potential Energy of Protein
In the context of chemistry and molecular modelling, a force field is a computational method that is used to estimate the forces between atoms within molecules and also between molecules. More precisely, the force field refers to the functional form and parameter sets used to calculate the potential energy of a system of atoms or coarse-grained particles in molecular mechanics, molecular dynamics, or Monte Carlo simulations. The parameters for a chosen energy function may be derived from experiments in physics and chemistry, calculations in quantum mechanics, or both. Force fields are interatomic potentials and utilize the same concept as force fields in classical physics, with the difference that the force field parameters in chemistry describe the energy landscape, from which the acting forces on every particle are derived as a gradient of the potential energy with respect to the particle coordinates. All-atom force fields provide parameters for every type of atom in a system, including hydrogen, while united-atom interatomic potentials treat the hydrogen and carbon atoms in methyl groups and methylene bridges as one interaction center. Coarse-grained potentials, which are often used in long-time simulations of macromolecules such as proteins, nucleic acids, and multi-component complexes, sacrifice chemical details for higher computing efficiency.

Solar Team
The University of Calgary Solar Car Team is a multi-disciplinary student-run solar car racing ("raycing") team at the University of Calgary, based in Calgary, Alberta, Canada . It was established to design and build a solar car to compete internationally in the American Solar Challenge (ASC) (previously named the North American Solar Challenge) and the World Solar Challenge (WSC). The team is primarily composed of undergraduate students studying Engineering, Business, Science, Arts and Kinesiology. The mission of the University of Calgary Solar Car Team is to educate the community about sustainable energy and to serve as an interdisciplinary project through which students and faculty from various departments can collaborate in supporting sustainable energy.

Stress–Energy Tensor
The stress–energy tensor, sometimes called the stress–energy–momentum tensor or the energy–momentum tensor, is a tensor quantity in physics that describes the density and flux of energy and momentum in spacetime, generalizing the stress tensor of Newtonian physics. It is an attribute of matter, radiation, and non-gravitational force fields. This density and flux of energy and momentum are the sources of the gravitational field in the Einstein field equations of general relativity, just as mass density is the source of such a field in Newtonian gravity.

Geary
Geary is a free and open-source email client written in Vala, which is based on WebKitGTK+. Although since adopted by the GNOME project, the project originally was developed by the Yorba Foundation. The purpose of this e-mail client, according to Adam Dingle, Yorba founder, was to bring back users from online webmails to a faster and easier to use desktop application. Pantheon Mail is a fork initiated by the Elementary OS community after the demise of Yorba.

Chumash Traditional Medicine
Chumash traditional medicine is a type of traditional medicine practiced by the Chumash people of the southern coastal regions of California . Chumash medicine focused on treating mind, spirit, and body alike to promote the wellness of both the individual and the larger community. Healing practices included a knowledge of local plants, as well as a mix of spiritual practices including prayer, singing, and dancing. Post-European contact, Chumash healers adapted these methods to treat changes in environment and the introduction of deadly diseases. Prevention was key in promoting health, and healers took responsibility for ensuring all people worked and felt valued in the community. In the modern day, certain medicinal practices are viewed as controversial, including the treatment of menstruating women, the use of sacred datura, and the consumption of dangerous polycyclic aromatic hydrocarbons.

Bush Encroachment in Namibia
Bush encroachment is a natural phenomenon characterised by the excessive expansion of bush at the expense of other plant species, especially grasses. Bush encroachment is estimated to affect up to 45 million ha of Namibian land and has severe negative consequences on key Ecosystem services, especially agricultural productivity and groundwater recharge. Agricultural productivity in Namibia has declined by two thirds throughout the past decades, mainly due to the negative impact of bush encroachment. The phenomenon affects both commercial and communal farming in Namibia, mostly the central, eastern and north-eastern regions.

Metallacarbaboranes
Metallacarbaboranes (or metallacarboranes) are compounds that contain cluster polyhedra comprising carbon, boron, and metal atoms in various combinations. Most of the structures of metallacarbaborane clusters derive from triangular-faced polyhedra. The most numerous examples are icosahedral and pentagonal bipyramidal cages.
