23Collaborative product development — (collaborative product design) (CPD) is a business strategy, work process and collection of software applications that facilitates different organizations to work together on the development of a product. It is also known as collaborative product …
24Renal blood flow — In the physiology of the kidney, renal blood flow (RBF) is the volume of blood delivered to the kidneys per unit time. In humans, the kidneys together receive roughly 25% of cardiac output, amounting to 1 L/min in a 70 kg adult male. RBF is… …

26deformation and flow — Alteration in size or shape of a body under the influence of mechanical forces. Flow is a change in deformation that continues as long as the force is applied. Gases and liquids normally flow relatively freely, while solids deform when subjected… …
27Potential flow — streamlines around a NACA 0012 airfoil at 11° angle of attack, with upper and lower streamtubes identified. In fluid dynamics, potential flow describes the velocity field as the gradient of a scalar function: the velocity potential. As a result,… …
28Selected ion flow tube mass spectrometry — is a sensitive and quantitative mass spectrometry technique for trace gas analyses using chemical ionisation of sample trace gases by selected positive ions during a well defined time period along a flow tube. Absolute concentrations of trace… …
29Cross-flow filtration — Diagram of cross flow filtration In chemical engineering, biochemical engineering and protein purification, crossflow filtration[1] (also known as tangential flow filtration[2 …
30Precambrian time — Interval of geologic time from с 3. 8 billion years ago, the age of the oldest known rocks, to 544 million years ago, the beginning of the Cambrian Period. This interval represents more than 80% of the geologic record and thus provides important… …
