LandscapingLandscaping refers to any activity that modifies the visible features of an area of land, including the following: Living elements, such as flora or fauna; or what is commonly called gardening, the art and craft of growing plants with a goal of creating a beauty within the landscape. Natural abiotic elements, such as landforms, terrain shape and elevation, or bodies of water. Abstract elements, such as the weather and lighting conditions. Landscaping requires a certain understanding of horticulture and artistic design, but is not limited to plants and horticulture.
Energy povertyEnergy poverty is lack of access to modern energy services. It refers to the situation of large numbers of people in developing countries and some people in developed countries whose well-being is negatively affected by very low consumption of energy, use of dirty or polluting fuels, and excessive time spent collecting fuel to meet basic needs. Today, 759 million people lack access to consistent electricity and 2.6 billion people use dangerous and inefficient cooking systems.
CondominiumA condominium (or condo for short) is an ownership regime in which a building (or group of buildings) is divided into multiple units that are either each separately owned, or owned in common with exclusive rights of occupation by individual owners. These individual units are surrounded by common areas that are jointly owned and managed by the owners of the units. The term can be applied to the building or complex itself, and is sometimes applied to individual units.
Geneva ConventionsThe Geneva Conventions are four treaties, and three additional protocols, that establish international legal standards for humanitarian treatment in war. The singular term Geneva Convention usually denotes the agreements of 1949, negotiated in the aftermath of the Second World War (1939–1945), which updated the terms of the two 1929 treaties and added two new conventions. The Geneva Conventions extensively define the basic rights of wartime prisoners, civilians and military personnel, established protections for the wounded and sick, and provided protections for the civilians in and around a war-zone.
Energy storageEnergy storage is the capture of energy produced at one time for use at a later time to reduce imbalances between energy demand and energy production. A device that stores energy is generally called an accumulator or battery. Energy comes in multiple forms including radiation, chemical, gravitational potential, electrical potential, electricity, elevated temperature, latent heat and kinetic. Energy storage involves converting energy from forms that are difficult to store to more conveniently or economically storable forms.
SocialSocial organisms, including human(s), live collectively in interacting populations. This interaction is considered social whether they are aware of it or not, and whether the exchange is voluntary or not. The word "social" derives from the Latin word socii ("allies"). It is particularly derived from the Italian Socii states, historical allies of the Roman Republic (although they rebelled against Rome in the Social War of 91–87 BC).
Peace movementA peace movement is a social movement which seeks to achieve ideals such as the ending of a particular war (or wars) or minimizing inter-human violence in a particular place or situation. They are often linked to the goal of achieving world peace. Some of the methods used to achieve these goals include advocacy of pacifism, nonviolent resistance, diplomacy, boycotts, peace camps, ethical consumerism, supporting anti-war political candidates, supporting legislation to remove profits from government contracts to the military–industrial complex, banning guns, creating tools for open government and transparency, direct democracy, supporting whistleblowers who expose war crimes or conspiracies to create wars, demonstrations, and political lobbying.
Canton of FribourgThe canton of Fribourg, also canton of Freiburg (Canton de Fribourg kɑ̃tɔ̃ d(ə) fʁibuʁ; Kanton Freiburg ˈfraɪbʊrɡ; Canton de Fribôrg cɛ̃ˈtɔ̃ də fʁiˈbwa Chantun Friburg Canton Friburgo) is located in western Switzerland. The canton is bilingual, with French spoken by more than two thirds of the citizens and German by a little more than a quarter. Both are official languages in the canton. The canton takes its name from its capital city of Fribourg. On the shores of Lake Neuchâtel and Lake Morat significant traces of prehistoric settlements have been unearthed.
Exterior algebraIn mathematics, the exterior algebra, or Grassmann algebra, named after Hermann Grassmann, is an algebra that uses the exterior product or wedge product as its multiplication. In mathematics, the exterior product or wedge product of vectors is an algebraic construction used in geometry to study areas, volumes, and their higher-dimensional analogues. The exterior product of two vectors and , denoted by is called a bivector and lives in a space called the exterior square, a vector space that is distinct from the original space of vectors.
Exterior derivativeOn a differentiable manifold, the exterior derivative extends the concept of the differential of a function to differential forms of higher degree. The exterior derivative was first described in its current form by Élie Cartan in 1899. The resulting calculus, known as exterior calculus, allows for a natural, metric-independent generalization of Stokes' theorem, Gauss's theorem, and Green's theorem from vector calculus.
