Lime tree stem, light micrograph Featured Print

Lime tree stem, light micrograph

Lime tree stem. Light micrograph of a section through the stem of a lime tree (Tilia europaea). The outer epidermis has been shed and replaced by a layer of cork (dark red). Under the cork is the outer cortex layer of flexible collenchyma tissue (dark blue and red) and a lower cortex of parenchyma (blue). Next is a ring of phloem (blue) with large sieve tubes, companion cells and fibres (pink). The phloem is broken by primary medullary rays (blue, triangular) and thin subsidiary medullary rays (dark blue). Next is a ring of xylem (pink) with large files of vessels and small woody parenchyma (light blue). The primary xylem (dark blue) and the central pith of parenchyma tissue (light blue) are also shown. Magnification: x5 when printed 10 centimetres

Potala Palace in Lhasa, Tibet 10 Featured Print

Potala Palace in Lhasa, Tibet 10

Lhasa, Tibet - October 2006
This is the imposing Palace of the 14th Dalai Lama, the spiritual leader of the Tibetan people, who fled to exile in India after the Chinese invasion and annexation of the country in 1959. These seemingly endless steps look almost abstract, don't they? With altitude sickness and at 3656m altitude, walking up these steps is a real killer. Seriously, don't try it unless super-fit and fully acclimatised

Drilling an Oil Well - Boring by Turbine Featured Print

Drilling an Oil Well - Boring by Turbine

Drilling an Oil Well - Boring by Turbine. Liquid mud is pumped at high pressure through a non-revolving pipe to a turbo drill (shown in the inset enlargement) at the bottom of the well. The casing of the turbo which is fixed to the pipe and therefore cannot revolve, contains a small turbine. As the mud flows through the turbine it makes it turn. The turbine's shaft is connected with the drill through gearing, so the drill also is rotated. Having done its work, the mud escapes at the bottom of the casing and flows back to the surface outside the pipe. Date: circa 1920s
