Kilogram-force

The kilogram-force (kgf or kg_F), or kilopond (kp, from Latin pondus meaning weight), is a gravitational metric unit of force. It is equal to the magnitude of the force exerted by one kilogram of mass in a 7000980665000000000♠9.80665 m/s² gravitational field (standard gravity, a conventional value approximating the average magnitude of gravity on Earth). Therefore one kilogram-force is by definition equal to 7000980665000000000♠9.80665 N. Similarly, a gram-force is 6997980665000000000♠9.80665 mN, and a milligram-force is 6994980664999999999♠9.80665 µN. One kilogram-force is approximately 2.204622 pounds-force.

Kilogram-force is a non-standard unit and does not comply with the SI Metric System.

History

The gram-force and kilogram-force were never well-defined units until the CGPM adopted a standard acceleration of gravity of 980.665 cm/s² for this purpose in 1901, though they had been used in low-precision measurements of force before that time. The kilogram-force has never been a part of the International System of Units (SI), which was introduced in 1960. The SI unit of force is the newton.

Pond (currency)

The pond was a currency unit issued in the Orange Free State and the South African Republic. It was prepared for, but not issued, in New Griqualand.

The word pond is Afrikaans for the word 'pound'. In fact, the South African pound banknotes of the South African Reserve Bank have the word 'Pond' inscribed, as do the banknotes of South West Africa that were issued between the 1930s and 1959.

Pond5

Pond5 is a New York based online marketplace for royalty-free media. The company licenses royalty-free footage, music, sound effects, after effects, images and 3-D models. They are reported to have the world's largest collection of stock video footage.

History

Pond5 was founded in 2006 as a way for video producers to license content to third parties. It subsequently expanded into other media types, including photos, music, sound effects, 3D models, and Adobe After Effects templates. Pond5 does not own the content on its site, but instead aggregates and sells content created and owned by its contributors. These contributors determine the selling price, and earn 50% of revenue.

In March 2013, Pond5 acquired Pixmac, a stock photography site based in the Czech Republic. The acquisition added Pixmac’s 6,000+ photographers and support for 17 languages to the Pond5 marketplace

In December 2013, the company surpassed 2 million video clips, and began accepting REDCODE native R3D files.

In January 2014, The Next Web reported that Pond5 partnered with Adobe to create a plugin for Adobe Premiere Pro integrating its collection with the editing suite.

Jasper Fish

Jasper Fish (buried 28 July 1791 at Sevenoaks, Kent) was a noted professional cricketer in the 18th century who was chiefly associated with Kent in the 1760s and 1770s.

Most of his career took place before cricket's statistical record began with regular scorecards in 1772 and he is recorded in only three major cricket matches in 1769, 1773 and 1777.

Fish anatomy

Fish anatomy is the study of the form or morphology of fishes. It can be contrasted with fish physiology, which is the study of how the component parts of fish function together in the living fish. In practice, fish anatomy and fish physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the latter dealing with how those components function together in the living fish.

The anatomy of fish is often shaped by the physical characteristics of water, the medium in which fish live. Water is much denser than air, holds a relatively small amount of dissolved oxygen, and absorbs more light than air does. The body of a fish is divided into a head, trunk and tail, although the divisions between the three are not always externally visible. The skeleton, which forms the support structure inside the fish, is either made of cartilage, in cartilaginous fish, or bone in bony fish. The main skeletal element is the vertebral column, composed of articulating vertebrae which are lightweight yet strong. The ribs attach to the spine and there are no limbs or limb girdles. The main external features of the fish, the fins, are composed of either bony or soft spines called rays, which with the exception of the caudal fins, have no direct connection with the spine. They are supported by the muscles which compose the main part of the trunk. The heart has two chambers and pumps the blood through the respiratory surfaces of the gills and on round the body in a single circulatory loop. The eyes are adapted for seeing underwater and have only local vision. There is an inner ear but no external or middle ear. Low frequency vibrations are detected by the lateral line system of sense organs that run along the length of the sides of fish, and these respond to nearby movements and to changes in water pressure.

Fish physiology

Fish physiology is the scientific study of how the component parts of fish function together in the living fish. It can be contrasted with fish anatomy, which is the study of the form or morphology of fishes. In practice, fish anatomy and physiology complement each other, the former dealing with the structure of a fish, its organs or component parts and how they are put together, such as might be observed on the dissecting table or under the microscope, and the later dealing with how those components function together in the living fish.

Respiration

Most fish exchange gases using gills on either side of the pharynx (throat). Gills are tissues which consist of threadlike structures called filaments. These filaments have many functions and "are involved in ion and water transfer as well as oxygen, carbon dioxide, acid and ammonia exchange. Each filament contains a capillary network that provides a large surface area for exchanging oxygen and carbon dioxide. Fish exchange gases by pulling oxygen-rich water through their mouths and pumping it over their gills. In some fish, capillary blood flows in the opposite direction to the water, causing countercurrent exchange. The gills push the oxygen-poor water out through openings in the sides of the pharynx.
