Additional restrictions instituted in July 2011 further limited the work hours of postgraduate year 1 (PGY-1) residents, threatening to reduce availability for educational and operative activities.
However, using "magic angle spinning" nuclear magnetic resonance spectroscopy, Zainuddin et al. [9] have shown that the HAp in the powder is consumed during the cement formation process in this material and so may in fact have reduced availability for bio-mineralization.
We now extend these data to show, for the first time, that this effect is most probably mediated via diminished activity of the ornithine cycle, reducing availability of substrate for polyamine biosynthesis to fuel microvascular cell development.
Structural studies have shown that by binding to and stimulating the ATPase activity of Grp78, intrinsically disordered proteins are constantly engaged in sequestering the "open" population of the chaperone, thus reducing availability of Grp78 for enabling the folding reactions of other ER-resident proteins.
We hypothesize that sagebrush treatments on DLL increased availability of grasses and forbs to sage-grouse, similar to other studies, but that cumulative annual reductions in sagebrush may have reduced availability of sagebrush cover for sage-grouse seasonal needs at DLL, especially when extreme winter weather occurred.
Loss of native grasslands by anthropogenic disturbances has reduced availability and connectivity of habitat for many grassland species.
Warming and drying exacerbate stresses in crop plants, potentially leading to catastrophic yield reductions: It reduces water availability for irrigation; it also reduces soil fertility through increased oxidation of soil organic carbon; and it also increases incidence of pests, diseases and weeds.
In the River Kinu, increased shading by the perennial alien grass Eragrostis curvula reduces light availability for A. kantoensis.
This hypothesis states that a disturbance regime (or pattern of disturbances) characterized by low frequency, limited gap size (that is, habitats containing only small areas cleared by disturbances), and low intensity reduces resource availability for many species.
At the same time, its familiar and ritualistic nature reduces its availability for conscious examination.
