Topics in urbanismUrbanism is the study of how inhabitants of urban areas, such as towns and cities, interact with the built environment. It is a direct component of disciplines such as urban planning, a profession focusing on the design and management of urban areas, and urban sociology, an academic field which studies urban life. Many architects, planners, geographers, and sociologists investigate the way people live in densely populated urban areas. There is a wide variety of different theories and approaches to the study of urbanism.
Pollution de l'eauvignette|Les détritus de type déchets ménagers sont souvent indicateurs de pollutions (métaux lourds, micro-organismes) posant des problèmes de santé publique, notamment dans les régions où les eaux de surfaces sont utilisées pour la boisson, la lessive, la vaisselle, se laver, faire la cuisine, etc.). vignette|Les pollutions les plus spectaculaires (par des sels de fer ici) ne sont pas toujours les plus toxiques, mais de fortes concentrations d'un produit non réputé toxique (fer, sel par exemple) peuvent faire disparaître la plupart des formes de vie.
Plasma lightingPlasma lamps are a type of electrodeless gas-discharge lamp energized by radio frequency (RF) power. They are distinct from the novelty plasma lamps that were popular in the 1980s. The internal-electrodeless lamp was invented by Nikola Tesla after his experimentation with high-frequency currents in evacuated glass tubes for the purposes of lighting and the study of high voltage phenomena. The first practical plasma lamps were the sulfur lamps manufactured by Fusion Lighting.
Topics in architectural engineeringArchitectural engineering or architecture engineering, also known as building engineering, is an engineering discipline that deals with the engineering systems - such as structural, mechanical, electrical, lighting, environmental, climate control, telecommunications, security, and other technologies used in buildings. From reduction of greenhouse gas emissions to the construction of resilient buildings, architectural engineers are at the forefront of addressing several major challenges of the 21st century.
Transfert thermiquevignette|alt=Autour d'un feu, des mains reçoivent sa chaleur par rayonnement (sur le côté), par convection (au-dessus de ses flammes) et par conduction (à travers un ustensile en métal).|Les modes de transfert thermique ( en anglais pour « rayonnement »). Un transfert thermique, appelé plus communément chaleur, est l'un des modes d'échange d'énergie interne entre deux systèmes, l'autre étant le travail : c'est un transfert d'énergie thermique qui s'effectue hors de l'équilibre thermodynamique.
Statistical mechanicsIn physics, statistical mechanics is a mathematical framework that applies statistical methods and probability theory to large assemblies of microscopic entities. It does not assume or postulate any natural laws, but explains the macroscopic behavior of nature from the behavior of such ensembles. Sometimes called statistical physics or statistical thermodynamics, its applications include many problems in the fields of physics, biology, chemistry, and neuroscience.
Matériau de constructionLes matériaux de construction sont des matériaux utilisés dans les secteurs de la construction : bâtiments et travaux publics (souvent désignés par le sigle BTP). Ils couvrent une vaste gamme des matériaux qui inclut principalement le bois, le verre, l'acier, l'aluminium, les textiles, les matières plastiques (isolants notamment) et les matériaux issus de la transformation de produits de carrières, qui peuvent être plus ou moins élaborés (incluant le béton et divers dérivés de l'argile tels que briques, tuiles, carrelages et divers éléments sanitaires).
Développement durablevignette|Diagramme de Venn du développement durable, à l'intersection de trois préoccupations, dites « les trois piliers du développement durable ».Les descriptions des intersections partielles peuvent varier. Le développement durable (, parfois traduit par développement soutenable) est une conception du développement qui s'inscrit dans une perspective de long terme et en intégrant les contraintes environnementales et sociales à l'économie.
Thermal engineeringThermal engineering is a specialized sub-discipline of mechanical engineering that deals with the movement of heat energy and transfer. The energy can be transferred between two mediums or transformed into other forms of energy. A thermal engineer will have knowledge of thermodynamics and the process to convert generated energy from thermal sources into chemical, mechanical, or electrical energy. Many process plants use a wide variety of machines that utilize components that use heat transfer in some way.
Environmental policyEnvironmental policy is the commitment of an organization or government to the laws, regulations, and other policy mechanisms concerning environmental issues. These issues generally include air and water pollution, waste management, ecosystem management, maintenance of biodiversity, the management of natural resources, wildlife and endangered species. For example, concerning environmental policy, the implementation of an eco-energy-oriented policy at a global level to address the issues of global warming and climate changes could be addressed.
