Rationale of New Grading System: Central Compartment Atopic Disease
International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Central compartment atopic disease (CCAD) has recently been recognized as a distinct phenotype within the spectrum of type 2–dominant chronic rhinosinusitis (CRS). Although international guidelines highlight polypoid changes in the central nasal cavity, standardized diagnostic and classification criteria are still lacking.

International Forum of Allergy &Rhinology, EarlyView.ABSTRACT Background Chronic rhinosinusitis (CRS) and olfactory dysfunction (OD) are highly prevalent among people with cystic fibrosis (PwCF) and negatively impact quality of life. The 40‐item Smell Identification Test (SIT) is widely used to assess psychophysical olfaction, but a CF‐specific minimal clinically important difference (MCID) has not been ...

Simulation of non-linear bearing forces for post-stability investigation [PDF]
Different types of bearing designs were developed to improve dynamic properties of rotor-bearing systems. Elliptical bearings, multisleeve bearings, tilting pad and other designs such as herringbone groove were utilized to increase resistance to the ...

Influence of design parameters on occurence of oil whirl [PDF]
Oil whirl instability is a serious problem in oil lubricated journal bearings. The phenomenon is characterized by a subsynchronous vibration of the journal within the bush and is particularly apparent in turbogenerators, aeroengines and electric motors ...

Bending vibration of an automotive turbocharger under the influence of rotor imbalance [PDF]
As one of the most common faults, rotor imbalance in a turbocharger will give rise to the bending vibration, which may cause damage to and even destroy the bearings and impellers. Therefore, it is necessary to detect rotor imbalance as early as possible.

Design curves for optimizing stability of herringbone-grooved journal bearings [PDF]
, 1973 Curves span wide range of operating conditions, including: lubricant compressibility numbers from 0 to 80, bearing length-to-diameter ratios from 1/4 to 2, and either rotating or stationary grooved ...

The Anatomical Record, EarlyView.Abstract To solidify their power over society, totalitarian regimes will usually eliminate any dissent, any perceived threats early on. These threats include not only political enemies but also educated and independent segments of society, such as professional associations.

The Anatomical Record, EarlyView.Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.
