L.D. Porta
Livio Dante Porta (21 March 1922 – 10 June 2003) was an Argentine steam locomotive engineer. He is particularly remembered for his innovative modifications to existing locomotive systems in order to obtain better performance and energy efficiency, and reduced pollution. He developed the Kylpor and Lempor exhaust systems. The Lemprex was under development at the time of his death. Early years Porta was born in Paraná, Entre Ríos, and studied civil engineering, concluding his studies in 1946, at a time when steam was already giving way to diesel and electric locomotives in Europe and North America. Career Naturally, Porta's first projects were in Argentina. Taking the work of Andre Chapelon in France as his starting point, he set out to demonstrate that the steam locomotive was far from reaching its maximum potential. His first locomotive project in 1948 took the remains of a 4-6-2 converting it into a 4-cylinder compound 4-8-0 named 'Presidente Peron'/'Argentina'. ...

Red De Ferrocarril Industrial De Rio Turbio
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It has a dominant wavelength of approximately 625–740 nanometres. It is a primary color in the RGB color model and a secondary color (made from magenta and yellow) in the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy. Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the ...

Forced Disappearance
An enforced disappearance (or forced disappearance) is the secret abduction or imprisonment of a person by a state or political organization, or by a third party with the authorization, support, or acquiescence of a state or political organization, followed by a refusal to acknowledge the person's fate and whereabouts, with the intent of placing the victim outside the protection of the law. According to the Rome Statute of the International Criminal Court, which came into force on 1 July 2002, when committed as part of a widespread or systematic attack directed at any civilian population, a "forced disappearance" qualifies as a crime against humanity, not subject to a statute of limitations, in international criminal law. On 20 December 2006, the United Nations General Assembly adopted the International Convention for the Protection of All Persons from Enforced Disappearance. Often, forced disappearance implies murder: a victim is abducted, may be illegally detained and of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Southern Fuegian Railway
The Southern Fuegian Railway ( es, Ferrocarril Austral Fueguino (FCAF)) or the Train of the End of the World ( es, El Tren del Fin del Mundo) is a gauge steam railway in Tierra del Fuego Province, Argentina. It was originally built as a freight line to serve the prison of Ushuaia, specifically to transport timber. It now operates as a heritage railway into the Tierra del Fuego National Park and is considered the southernmost functioning railway in the world. History Origins century, Ushuaia on Isla Grande de Tierra del Fuego developed as a penal colony, with the first prisoners arriving in 1884. In 1902, work began on a proper set of buildings for the prison by inmates, and a railway on wooden rails was constructed to assist the transport of materials, mainly local rock, sand and timber. Oxen pulled wagons along the narrow gauge of less than . In 1909, the prison governor informed the government of the need to upgrade the line and Decauville tracks at a narrow gauge wer ...

Garratt
A Garratt (often referred to as a Beyer Garratt) is a type of steam locomotive invented by British engineer Herbert William Garratt that is articulated into three parts. Its boiler, firebox, and cab are mounted on a centre frame or "bridge". The two other parts, one at each end, have a pivot to support the central frame; they consist of a steam engine unit – with driving wheels, trailing wheels, valve gear, and cylinders, and above it, fuel and/or water storage. Articulation permits locomotives to negotiate curves that might restrict large rigid-framed locomotives. The design also provides more driving wheels per unit of locomotive weight, permitting operation on lightly engineered track. Garratt locomotives produced as much as twice the power output of the largest conventional locomotives of railways that introduced them, reducing the need for multiple locomotives and crews. Advantages of the Garratt concept The principal benefit of the Garratt design is that the boil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Track Gauge
In rail transport, track gauge (in American English, alternatively track gage) is the distance between the two rails of a railway track. All vehicles on a rail network must have wheelsets that are compatible with the track gauge. Since many different track gauges exist worldwide, gauge differences often present a barrier to wider operation on railway networks. The term derives from the metal bar, or gauge, that is used to ensure the distance between the rails is correct. Railways also deploy two other gauges to ensure compliance with a required standard. A '' loading gauge'' is a two-dimensional profile that encompasses a cross-section of the track, a rail vehicle and a maximum-sized load: all rail vehicles and their loads must be contained in the corresponding envelope. A ''structure gauge'' specifies the outline into which structures (bridges, platforms, lineside equipment etc.) must not encroach. Uses of the term The most common use of the term "track gauge" refers to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
5AT Advanced Technology Steam Locomotive
The 5AT Advanced Technology steam locomotive was a conceptual design conceived by the British engineer David Wardale, and first described in his definitive work on modern steam, ''The Red Devil and Other Tales from the Age of Steam.'' Wardale's purpose in putting forward the "Super Class 5 4-6-0" design concept (as he then called it) was to offer a future for steam hauled trains on the main lines in the UK on which the use of heritage traction is likely to be gradually phased out as the speed and density of commercial rail traffic increase. Work on the project was suspended in March 2012 following completion of a project Feasibility Study and subsequent failure to raise the finance needed to complete the detail design and construction of the locomotive. Proposal Wardale's proposal was for a locomotive that would: * be acceptable to the British railway authorities by conforming with the size and weight of the BR 5MT Class 4-6-0 locomotives that have operated on British main li ...

Bagasse
Bagasse ( ) is the dry pulpy fibrous material that remains after crushing sugarcane or sorghum stalks to extract their juice. It is used as a biofuel for the production of heat, energy, and electricity, and in the manufacture of pulp and building materials. Agave bagasse is similar, but is the material remnants after extracting blue agave sap. Etymology The word comes from ''bagage'' (French) and ''bagazo'' (Spanish), meaning ''refuse'' or ''trash''. It originally referred to the material left after pressing olives, palm nuts, and grapes. The word eventually came to be used in the context of processing of plants such as sugarcane and sugar beets. Today, it usually refers to by-products of the sugarcane mill. Description Bagasse is the solid by-product when the liquid components are extracted from plants. Much of the core of those plants is a heterogeneous "pith" fibre. This fibre is primarily parenchyma tissue, along with bast, rind, or stem fibers of the sclerenchyma. Here's an ...

Thermodynamics
Thermodynamics is a branch of physics that deals with heat, work, and temperature, and their relation to energy, entropy, and the physical properties of matter and radiation. The behavior of these quantities is governed by the four laws of thermodynamics which convey a quantitative description using measurable macroscopic physical quantities, but may be explained in terms of microscopic constituents by statistical mechanics. Thermodynamics applies to a wide variety of topics in science and engineering, especially physical chemistry, biochemistry, chemical engineering and mechanical engineering, but also in other complex fields such as meteorology. Historically, thermodynamics developed out of a desire to increase the efficiency of early steam engines, particularly through the work of French physicist Sadi Carnot (1824) who believed that engine efficiency was the key that could help France win the Napoleonic Wars. Scots-Irish physicist Lord Kelvin was the first to formulate a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
