Solution (chemistry)In chemistry, a solution is a special type of homogeneous mixture composed of two or more substances. In such a mixture, a solute is a substance dissolved in another substance, known as a solvent. If the attractive forces between the solvent and solute particles are greater than the attractive forces holding the solute particles together, the solvent particles pull the solute particles apart and surround them. These surrounded solute particles then move away from the solid solute and out into the solution.
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.
Energy economicsEnergy economics is a broad scientific subject area which includes topics related to supply and use of energy in societies. Considering the cost of energy services and associated value gives economic meaning to the efficiency at which energy can be produced. Energy services can be defined as functions that generate and provide energy to the “desired end services or states”. The efficiency of energy services is dependent on the engineered technology used to produce and supply energy. The goal is to minimise energy input required (e.
Mila (research institute)Mila - Quebec AI Institute (originally Montreal Institute for Learning Algorithms) is a research institute in Montreal, Quebec, focusing mainly on machine learning research. Approximately 1000 students and researchers and 100 faculty members, were part of Mila in 2022. Mila is part of the Pan-Canadian AI Strategy. Mila traces its foundations to the Laboratoire d'informatique des systèmes adaptatifs (LISA) at the Université de Montréal and to the Reasoning and Learning Lab (RL-Lab) at McGill University.
Energy conservationEnergy conservation is the effort to reduce wasteful energy consumption by using fewer energy services. This can be done by using energy more effectively (using less energy for continuous service) or changing one's behavior to use less service (for example, by driving less). Energy conservation can be achieved through efficient energy use, which has some advantages, including a reduction in greenhouse gas emissions and a smaller carbon footprint, as well as cost, water, and energy savings.
CT scanA computed tomography scan (usually abbreviated to CT scan; formerly called computed axial tomography scan or CAT scan) is a medical imaging technique used to obtain detailed internal images of the body. The personnel that perform CT scans are called radiographers or radiology technologists. CT scanners use a rotating X-ray tube and a row of detectors placed in a gantry to measure X-ray attenuations by different tissues inside the body.
PET-CTPositron emission tomography–computed tomography (better known as PET-CT or PET/CT) is a nuclear medicine technique which combines, in a single gantry, a positron emission tomography (PET) scanner and an x-ray computed tomography (CT) scanner, to acquire sequential images from both devices in the same session, which are combined into a single superposed () image. Thus, functional imaging obtained by PET, which depicts the spatial distribution of metabolic or biochemical activity in the body can be more precisely aligned or correlated with anatomic imaging obtained by CT scanning.
RenaixençaThe Renaixença (rənəˈʃɛnsə; also written Renaixensa before spelling standardisation), or Catalan Renaissance, was a romantic revivalist movement in Catalan language and culture through the mid 19th century, akin to the Galician Rexurdimento or the Occitan Félibrige movements. The movement began in the 1830s and lasted until the 1880s, when it branched out into other cultural movements. Even though it primarily followed a romantic impulse, it incorporated stylistic and philosophical elements of other 19th century movements such as Naturalism or Symbolism.
Aleix ClapésAlex Clapés (Vilassar de Dalt, September 10, 1850 – Barcelona, 1920) was a Catalan modernisme artist. He was one of the less known painters in the late 19th century and early 20th century in Catalonia, Spain. He was born in Vilassar de Dalt on September 10, 1850. He died in Barcelona in 1920. He is most known for performing some commissions for the Güell family, thanks to his friend and colleague, Antoni Gaudí. Clapés was born in Vilassar de Dalt, Catalonia, in 1850. Very little information is known about his personal life.
Public art in BarcelonaPublic art in Barcelona is a designated group of monuments and outdoor sculptures in the city. The artworks in city's architecture and network of museums, parks, and gardens, put an artistic stamp on the Catalan capital. Public art in the city developed in the 19th century, although the first municipal commission was the 1673 monument to Saint Eulalia in Pedró Square. Artworks are typically located in niches and on the façades of public buildings. They are concentrated because of the city's enclosure by medieval defensive walls.
Museum of Lebanese PrehistoryThe Museum of Lebanese Prehistory (Musée de Préhistoire Libanaise, متحف ما قبل التاريخ اللبناني) is a museum of prehistory and archaeology in Beirut, Lebanon. The museum is the first museum of prehistory in the Middle East and was opened in June 2000 to commemorate the 125th anniversary of Saint Joseph University of Beirut. The founding of the museum followed from the work of Jesuit scholars who controlled prehistoric research in this part of the world until the 1950s.
