Exempel på hur man kan använda SELECTIVITY i en mening

• The model does not account for fading, frequency selectivity, interference, nonlinearity or dispersion.
• This problem is greatly reduced by even moderate-quality receivers, which have better selectivity (filtering) and dynamic range than poorly designed inexpensive or disposable ones.
• Callenbach's Ecotopian concept is not "Luddite" — he does not reject high technology, but rather his fictional society shows a conscious selectivity about technology.
• Advantages of regenerative receivers include increased sensitivity with modest hardware requirements, and increased selectivity because the Q of the tuned circuit will be increased when the amplifying vacuum tube or transistor has its feedback loop around the tuned circuit (via a "tickler" winding or a tapping on the coil) because it introduces some negative resistance.
• The main disadvantage of FIR filters is that considerably more computation power in a general purpose processor is required compared to an IIR filter with similar sharpness or selectivity, especially when low frequency (relative to the sample rate) cutoffs are needed.
• The radioligand must be radiochemically pure, stable, and demonstrate a high degree of selectivity, and high affinity for their target.
• Studies have suggested that interference with certain post-translational modification processes seem to have quite a high selectivity for targeting cells displaying tumour phenotypes, although the reason for this is a matter of controversy.
• However, the degree of size selectivity is restricted by the hiding effect described by Parker and Klingeman (1982), wherein larger particles protrude from the bed whereas small particles are shielded and hidden by larger particles, with the result that nearly all grain sizes become entrained at nearly the same shear stress.
• Some important features of active transport in addition to its ability to intervene even against a gradient, its kinetics and the use of ATP, are its high selectivity and ease of selective pharmacological inhibition.
• Targeting selectivity for COX-2 reduces the risk of peptic ulceration and is the main feature of celecoxib, rofecoxib, and other members of this drug class.
• In 1958, Hubel moved to Johns Hopkins and began his collaborations with Wiesel, and discovered orientation selectivity and columnar organization in the visual cortex.
• The causes for the extinction of the steppe bison and many other primarily megafaunal species remain hotly debated, but the selectivity for large animals suggests that the spread of modern humans played a substantial role.
• That kind of selectivity discredits pro-Palestinian campaigners and dishonours the principles of equality and human rights.
• Such impact can be regulated by using larger meshes, however compared to gillnets the selectivity of trammel nets are lower and catches of small organisms and non-target species are common.
• Radios for shortwave reception generally have higher performance than those intended for the local mediumwave, longwave or FM broadcast band, since dependable reception of shortwave signals requires a radio with increased sensitivity, selectivity, dynamic range and frequency stability.
• Because it has some selectivity for cerebral vasculature, nimodipine's main use is in the prevention of cerebral vasospasm and resultant ischemia, a complication of subarachnoid hemorrhage (a form of cerebral bleed), specifically from ruptured intracranial berry aneurysms irrespective of the patient's post-ictus neurological condition.
• A subsequent scientific collaboration was ultimately formed among SRI International, Memorial Sloan Kettering Cancer Center, and the Southern Research Institute with the intention of developing an antifolate with greater therapeutic selectivity – an agent that could be more effectively internalized into tumors (transported into the cells through RFC-1) and would be more toxic to cancer cells than normal cells.
• Its structure is different from that of other COX-2 inhibitors, such as celecoxib: lumiracoxib is an analogue of diclofenac (one chlorine substituted by fluorine, the phenylacetic acid has another methyl group in meta position), making it a member of the arylalkanoic acid class of NSAIDs; it binds to a different site on the COX-2 enzyme than do other COX-2 inhibitors; it is the only acidic coxib and has the highest COX-2 selectivity of any NSAID.
• Steric hindrance is often exploited to control selectivity, such as slowing unwanted side-reactions.
• At Cambridge-based KLH, Kloss continued to build speakers such as the classic KLH Model Five and Six, and produced one of the first small FM radios with high selectivity, the Model Eight.
