Tropical Helmet
The pith helmet, also known as the safari helmet, salacot, sola topee, sun helmet, topee, and topi) is a lightweight cloth-covered helmet made of sholapith. The pith helmet originates from the Spanish military adaptation of the native ''salakot'' headgear of the Philippines. It was often worn by European travellers and explorers, in the varying climates found in Southeast Asia, Africa, and the tropics, but was also used in many other contexts. It was routinely issued to European military personnel serving overseas in hot climates from the mid-nineteenth to the mid-twentieth century. Definition Typically, a pith helmet derives from either the sola plant, '' Aeschynomene aspera'', an Indian swamp plant, or from ''Aeschynomene paludosa''. In the narrow definition, a pith helmet is technically a type of sun helmet made out of pith material. However, the pith helmet may more broadly refer to the particular style of helmet. In this case, a pith helmet can be made out of cork, fibrous ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pith Helmet - Royal Canadian Military Institute - Toronto, Canada - DSC00325
Pith, or medulla, is a tissue in the stems of vascular plants. Pith is composed of soft, spongy parenchyma cells, which in some cases can store starch. In eudicotyledons, pith is located in the center of the stem. In monocotyledons, it extends also into flowering stems and roots. The pith is encircled by a ring of xylem; the xylem, in turn, is encircled by a ring of phloem. While new pith growth is usually white or pale in color, as the tissue ages it commonly darkens to a deeper brown color. In trees pith is generally present in young growth, but in the trunk and older branches the pith often gets replaced – in great part – by xylem. In some plants, the pith in the middle of the stem may dry out and disintegrate, resulting in a hollow stem. A few plants, such as walnuts, have distinctive chambered pith with numerous short cavities (See image at middle right). The cells in the peripheral parts of the pith may, in some plants, develop to be different from cells in the res ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bamboo
Bamboos are a diverse group of evergreen perennial flowering plants making up the subfamily Bambusoideae of the grass family Poaceae. Giant bamboos are the largest members of the grass family. The origin of the word "bamboo" is uncertain, but it probably comes from the Dutch or Portuguese language, which originally borrowed it from Malay or Kannada. In bamboo, as in other grasses, the internodal regions of the stem are usually hollow and the vascular bundles in the cross-section are scattered throughout the stem instead of in a cylindrical arrangement. The dicotyledonous woody xylem is also absent. The absence of secondary growth wood causes the stems of monocots, including the palms and large bamboos, to be columnar rather than tapering. Bamboos include some of the fastest-growing plants in the world, due to a unique rhizome-dependent system. Certain species of bamboo can grow within a 24-hour period, at a rate of almost an hour (equivalent to 1 mm every 90 seco ...

Aceh War
The Aceh War ( id, Perang Aceh), also known as the Dutch War or the Infidel War (1873–1913), was an armed military conflict between the Sultanate of Aceh and the Kingdom of the Netherlands which was triggered by discussions between representatives of Aceh and the United States in Singapore during early 1873.Ricklefs (2001), p. 185–88 The war was part of a series of conflicts in the late 19th century that consolidated Dutch rule over modern-day Indonesia. The campaign drew controversy in the Netherlands as photographs and accounts of the death toll were reported. Isolated bloody insurgencies continued as late as 1914 and less violent forms of Acehnese resistance continued to persist until World War II and the Japanese occupation. Background For much of the 19th century, Aceh's independence had been guaranteed by the Anglo-Dutch Treaty of 1824 and its status as a protectorate of the Ottoman Empire since the 16th century. During the 1820s, Aceh became a regional political a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
