Chronic Kidney Disease
Chronic kidney disease (CKD) is a type of kidney disease in which a gradual loss of kidney function occurs over a period of months to years. Initially generally no symptoms are seen, but later symptoms may include leg swelling, feeling tired, vomiting, loss of appetite, and confusion. Complications can relate to hormonal dysfunction of the kidneys and include (in chronological order) high blood pressure (often related to activation of the renin–angiotensin system system), bone disease, and anemia. Additionally CKD patients have markedly increased cardiovascular complications with increased risks of death and hospitalization. Causes of chronic kidney disease include diabetes, high blood pressure, glomerulonephritis, and polycystic kidney disease. Risk factors include a family history of chronic kidney disease. Diagnosis is by blood tests to measure the estimated glomerular filtration rate (eGFR), and a urine test to measure albumin. Ultrasound or kidney biopsy may ...

Complete Knock Down
A knock-down kit (also knockdown kit, knocked-down kit, or simply knockdown or KD) is a collection of parts required to assemble a product. The parts are typically manufactured in one country or region, then exported to another country or region for final assembly. A common form of knock-down is a complete knock-down (CKD), which is a kit of entirely unassembled parts of a product. It is also a method of supplying parts to a market, particularly in shipping to foreign nations, and serves as a way of counting or pricing. CKD is a common practice in the automotive, bus, heavy truck, and rail vehicle industries, as well as electronics, furniture and other products. Businesses sell knocked-down kits to their foreign affiliates or licensees for various reasons, including the avoidance of import taxes, to receive tax preferences for providing local manufacturing jobs, or even to be considered as a bidder at all (for example, in public transport projects with "buy national" rules). A ...

Count Key Data
Count key data (CKD) is a direct-access storage device (DASD) data recording format introduced in 1964, by IBM with its IBM System/360 and still being emulated on IBM mainframes. It is a self-defining format with each data record represented by a Count Area that identifies the record and provides the number of bytes in an optional Key Area and an optional Data Area. This is in contrast to devices using Fixed-block architecture, fixed sector size or a separate format track. Count key data (CKD) also refers to the set of channel commands (collectively Channel Command Words, CCWs) that are generated by an IBM mainframe for execution by a DASD subsystem employing the CKD recording format. The initial set of CKD CCWs, introduced in 1964, was substantially enhanced and improved into the 1990s. CKD Track Format "The beginning of a track is signalled when the index marker (index point) is detected.… The marker is automatically recognized by a special sensing device." Following th ...

ÄŒKD
ČKD (Českomoravská Kolben-Daněk) () was one of the largest engineering companies in the former Czechoslovakia and today's Czech Republic. It is famous for the Tatra T3, a tramcar that sold 13,991 units worldwide. History ČKD was formed in 1927 from the merger of two smaller companies, Českomoravská-Kolben (founded 1896, produced machinery for hydro dams) and Breitfeld-Daněk (founded 1854, produced machinery for mines and food industry). From 1927 until 1929 ČKD's products included a motorcycle designed by Jaroslav František Koch. It was an advanced four-stroke single- cylinder unit construction double overhead camshaft design of 500cc. It was sold under the marque BD, thus perpetuating the Breitfeld-Daněk identity. In 1929 ČKD sold its motorcycle business to Praga Hostivař, which re-branded the motorcycles under the Praga marque. It was one of the main suppliers to the Czechoslovak state of military vehicles during the 1930s. During the German occupation of Cz ...
