Macro-engineering
In engineering, macro-engineering (alternatively known as macroengineering or macro engineering and as mega engineering) is the implementation of extremely large-scale design projects. It can be seen as a branch of civil engineering or structural engineering but just on a very large land area. In particular, macro-engineering is the process of marshaling and managing of resources, technology and public opinion on a large scale to carry out complex tasks that last over a long period. In contrast to conventional engineering projects, macro-engineering projects (called macro-projects or mega-projects) are multidisciplinary, involving collaboration from all fields of study; they involve not only engineers, but scientists, lawyers, industrialists, soldiers and politicians as well. Macro-projects are usually international; they override political boundaries because most countries lack the social, financial or physical ability to undertake them alone. As a consequence, macro-projects have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Atlantropa
Atlantropa, also referred to as Panropa, was a gigantic engineering and colonisation idea that was devised by the German architect Herman Sörgel in the 1920s, and promoted by him until his death in 1952. The project was devised to contain several hydroelectric dams in key points of the Mediterranean Sea, such as the Strait of Gibraltar and the Bosporus, to cause a sea level drop and create new land to settle. Design The central feature of the Atlantropa proposal was to build a hydroelectric dam across the Strait of Gibraltar, which would have generated enormous amounts of hydroelectricity and would have led to the lowering of the surface of the Mediterranean Sea by up to , opening up large new lands for settlement, such as in the Adriatic Sea. The project proposed four additional major dams as well: * Across the Dardanelles to hold back the Black Sea * Between Sicily and Tunisia to provide a roadway and lower the inner Mediterranean further * On the Congo River below its ...

Ecotechnology
Ecotechnology is an applied science that seeks to fulfill human needs while causing minimal ecological disruption, by harnessing and manipulating natural forces to leverage their beneficial effects. Ecotechnology integrates two fields of study: the 'ecology of technics' and the 'technics of ecology,' requiring an understanding of the structures and processes of ecosystems and societies. All sustainable engineering that can reduce damage to ecosystems, adopt ecology as a fundamental basis, and ensure conservation of biodiversity and sustainable development may be considered as forms of ecotechnology. Ecotechnology emphasizes approaching a problem from a holistic point of view. For example, remediation of rivers should not only consider one single area. Rather, the whole catchment area, which includes the upstream, middle stream and downstream sections, should be considered. Construction can reduce its impact on nature by consulting experts on the environment. Sustainable devel ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Panama Canal
The Panama Canal ( es, Canal de Panamá, link=no) is an artificial waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean and divides North and South America. The canal cuts across the Isthmus of Panama and is a Channel (geography), conduit for maritime trade. One of the largest and most difficult engineering projects ever undertaken, the Panama Canal shortcut greatly reduces the time for ships to travel between the Atlantic and Pacific oceans, enabling them to avoid the lengthy, hazardous Cape Horn route around the southernmost tip of South America via the Drake Passage or Strait of Magellan and the even less popular route through the Arctic Archipelago and the Bering Strait. Colombia, France, and later the United States controlled the territory surrounding the canal during construction. France began work on the canal in 1881, but stopped because of lack of investors' confidence due to engineering problems and a high worker mortality rate. The United Stat ...

Suez Canal
The Suez Canal ( arz, قَنَاةُ ٱلسُّوَيْسِ, ') is an artificial sea-level waterway in Egypt, connecting the Mediterranean Sea to the Red Sea through the Isthmus of Suez and dividing Africa and Asia. The long canal is a popular trade route between Europe and Asia. In 1858, Ferdinand de Lesseps formed the Suez Canal Company for the express purpose of building the canal. Construction of the canal lasted from 1859 to 1869. The canal officially opened on 17 November 1869. It offers vessels a direct route between the North Atlantic and northern Indian oceans via the Mediterranean Sea and the Red Sea, avoiding the South Atlantic and southern Indian oceans and reducing the journey distance from the Arabian Sea to London by approximately , or 10 days at to 8 days at . The canal extends from the northern terminus of Port Said to the southern terminus of Port Tewfik at the city of Suez. In 2021, more than 20,600 vessels traversed the canal (an average of 56 per d ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in ...

Megascale Engineering
Megascale engineering (or macro-engineering) is a form of exploratory engineering concerned with the construction of structures on an enormous scale. Typically these structures are at least in length—in other words, at least one megameter, hence the name. Such large-scale structures are termed megastructures. In addition to large-scale structures, megascale engineering is also defined as including the transformation of entire planets into a human-habitable environment, a process known as terraforming or planetary engineering. This might also include transformation of the surface conditions, changes in the planetary orbit, and structures in orbit intended to modify the energy balance. Astroengineering is the extension of ''megascale engineering'' to megastructures on a stellar scale or larger, such as Dyson spheres, Ringworlds, and Alderson disks. Several megascale structure concepts such as Dyson spheres, Dyson swarms, and Matrioshka brains would likely be built upon s ...

Ecological Engineering
Ecological engineering uses ecology and engineering to predict, design, construct or restore, and manage ecosystems that integrate " human society with its natural environment for the benefit of both".W.J.

Deforestation During The Roman Period
Deforestation during the Roman period was a result of the geographical expansion of the Roman Empire, with its increased population, large-scale agriculture, and unprecedented economic development. Roman expansion marks the transition in the Mediterranean from prehistory (around 1,000 BC) to the historical period beginning around 500 BC. Earth sustained a few million people 8,000 years ago and was still fundamentally pristine, but Rome drove human development in Western Europe and was a leading contributor of the deforestation around the Mediterranean. Causes Housing and building The most basic building supply in the Roman time period was wood. Trees were cut to house increasing populations throughout the Roman Empire. While some Mediterranean houses were built with brick and stone, roof structures, covered with tiles, as well as the floors in multistory apartment buildings were often made of wood. It is estimated that at one point the Roman Empire had a population of 56.8 million ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collaborative Innovation Network
Collaborative innovation is a process in which multiple players contribute towards creating new products with customers and suppliers. Collaboration can occur in all aspects of the business cycle, depending on the context: * Procurement and supplier collaboration * Research and development of new products, services and technologies * Marketing, distribution and commercialization Collaborative innovation network (CoIN) is a type of collaborative innovation practice that makes use of the internet platforms such as email, chat, social networks, blogs, and Wikis to promote communication and innovation within self-organizing virtual teams. The difference is that people that collaborate in CoIN are so intrinsically motivated that might not be paid nor get any advantage. Thus, a CoIN is a social construct with a huge potential for innovation. It has been defined by the originator of the term, Peter Gloor from MIT Sloan's Center for Collective Intelligence, as "a cyberteam of self- mo ...

Biomass (ecology)
The biomass is the mass of living biological organisms in a given area or ecosystem at a given time. Biomass can refer to ''species biomass'', which is the mass of one or more species, or to ''community biomass'', which is the mass of all species in the community. It can include microorganisms, plants or animals. The mass can be expressed as the average mass per unit area, or as the total mass in the community. How biomass is measured depends on why it is being measured. Sometimes, the biomass is regarded as the natural mass of organisms ''in situ'', just as they are. For example, in a salmon fishery, the salmon biomass might be regarded as the total wet weight the salmon would have if they were taken out of the water. In other contexts, biomass can be measured in terms of the dried organic mass, so perhaps only 30% of the actual weight might count, the rest being water. For other purposes, only biological tissues count, and teeth, bones and shells are excluded. In some appl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
