Wskaźniki emisji CO2 opierajÄ… siÄ™ na zawartoÅ›ci wÄ™gla [C] w paliwach lub materiaÅ‚ach wsadowych. Wyraża siÄ™ je jako współczynniki spalania [Mg CO2/TJ] lub współczynniki procesu [Mg CO2/Mg albo Mg CO2/tys. m³]. Wskaźniki emisji CO2 oraz sposoby wyznaczania wskaźników emisji dla konkretnych rodzajów instalacji, . Do monitorowania wielkoÅ›ci emisji CO2 można stosować wzglÄ™dem paliw wskaźnik emisji CO2 ze spalania oparty na zawartoÅ›ci wÄ™gla w paliwach wyrażony jako [Mg CO2/Mg], jeżeli pozwala to uzyskać w trybie ciÄ…gÅ‚ym co najmniej takÄ… samÄ… dokÅ‚adność wyników. W takim przypadku należy okresowo ustalać wartość opaÅ‚owÄ… paliwa.

During its reign, Joseon consolidated its absolute rule over Korea, encouraged the entrenchment of Confucian ideals and doctrines in Korean society, imported and adopted Chinese culture, and saw the height of classical Korean culture, trade, science, literature, and technology. However, the dynasty was severely weakened during the late 16th and early 17th centuries, when successive invasions by neighboring Japan and Qing China virtually overran the peninsula, leading to an increasingly harsh isolationist policy for which the country became known as the Hermit Kingdom. However, whatever power the kingdom recovered during its isolation further waned as the 18th century came to a close, and faced with internal strife, power struggles, international pressure and rebellions at home, the Joseon Dynasty declined rapidly in the late 19th century. In 1895, The Joseon Dynasty was forced to write a document of independency from the Qing Dynasty after the Japanese victory in the First Sino-Japanese War and its peace treaty, the Treaty of Shimonoseki. From 1897 to 1910, Korea was formally known as the Korean Empire to signify a sovereign nation no longer a tributary of the Qing Dynasty. The Joseon Dynasty came to an end in 1910, when the Japan-Korea Annexation Treaty was enforced by the Empire of Japan.

Modern wire rope was invented by the German mining engineer Wilhelm Albert in the years between 1831 and 1834 for use in mining in the Harz Mountains in Clausthal, Lower Saxony, Germany. It was quickly accepted because it proved superior to ropes made of hemp or to metal chains, such as had been used before.

Wilhelm Albert’s first ropes consisted of wires twisted about a hemp rope core, six such strands then being twisted around another hemp rope core in alternating directions for extra stability. Earlier forms of wire rope had been made by covering a bundle of wires with hemp.

In America wire rope was later manufactured by John A. Roebling, forming the basis for his success in suspension bridge building. Roebling introduced a number of innovations in the design, materials and manufacture of wire rope.

Manufacturing a wire rope is similar to making one from natural fibres. The individual wires are first twisted into a strand, then six or so such strands again twisted around a core. This core may consist of steel, but also of natural fibres such as sisal, manila, henequen, jute, or hemp. This is used to cushion off stress forces when bending the rope.

This flexibility is particularly vital in ropes used in machinery such as cranes or elevators as well as ropes used in transportation modes such as cable cars, cable railways, funiculars and aerial lifts. It is not quite so essential in suspension bridges and similar uses.

Wire rope is often sold with vinyl and nylon coatings. This increases weather resistance and overall durability, however it can lead to weak joints if the coating is not removed correctly underneath joints and connections.
