Vad är ett Kreatininprov?
Blodprov som visar halten kreatinin i blodet är ett av de vanligaste blodproven. Provet tas för att läkaren ska få en uppfattning om hur dina njurar fungerar. Kreatininprov kan tas i samband med en undersökning men det kan också tas inför en behandling med vissa typer av läkemedel.
What is clearance fit?
Clearance Fit: A fit that always provides a clearance (gap) between the hole and shaft when assembled is known as clearance fit. In clearance fit, the minimum size of the hole is either greater than or, equal to (in extreme case) the maximum size of the shaft, so that the shaft can rotate or slide as per the purpose of the assembled members.
What is the difference between tolerance tolerance and clearance fit?
Tolerance: The difference between the maximum and minimum size limits of a part. Clearance Fit: A fit type where clearance exists between assembled parts under all tolerance conditions. Interference Fit: A fit type where interference exists between assembled parts under all tolerance conditions.
What clearances do you look for in a crankshaft?
Minimal clearances for high accuracy requirements, which can be easily assembled and will turn & slide freely, e.g., guiding of shafts, sliding gears, crankshaft journals Very close clearances for precise accuracy requirements, which can be assembled without force and will turn & slide when lubricated, e.g., precise guiding of shafts
What is a close-running fit?
Very close clearances for precise accuracy requirements, which can be assembled without force and will turn & slide when lubricated, e.g., precise guiding of shafts For example, using an H8/f7 close-running fit on a 50 mm diameter:
Hur kontrollerar man njurfunktionen?
Undersökningar. Njurfunktionen mäts genom undersökning av kreatininhalten i blodet. Kreatinin är en slutprodukt av musklernas ämnesomsättning och vid nedsatt njurfunktion avlägsnar njurarna inte kreatinin från blodet på normalt sätt, och därmed ökar dess halt i blodet.
