The nucleosome appears to be the basic structural unit of the
eukaryotic chromosome. The usual nucleosome preparation, isolated
from a micrococcal nuclease digest of nuclei, is heterogenous in DNA
length and protein composition with some particles containing spacer
DNA and associated protein. This heterogeneity complicated physical
and reconstitution studies. As...
An econometric model of the canned tuna market is used to evaluate biased and unbiased estimators. Four methods for improving mean square error when multicollinearity is present in a regression equation are examined and compared with the results of ordinary least squares (OLS). Exact and inexact prior information methods are...
Natural landscapes around the world have experienced serious loss and degradation, which negatively impacts ecosystem service provision by these landscapes. As a result, there have been serious investments to restore natural capital. However, restoration faces complex trade-offs, such as that between restoration quality, or how closely the restored landscapes resembles...
This report is one of a series prepared by the Oregon Department of Fish and Wildlife (ODFW) which summarizes the physical and biological data for selected Oregon estuaries. The reports are intended to assist coastal planners and resource managers in Oregon fulfilling the inventory and comprehensive plan requirements of the...
Solutions to the variable permeability magnetostatic field
problem are achieved in both rectangular and cylindrical coordinates
for a wide variety of magnet geometries. The resulting
difference equations are solved iteratively and a method is
provided which substantially increases the rate of convergence
for these type of problems. Magnetization curves for...
Appendices include the report "Crisis in Oregon's Estuaries" from the Oregon Chapter of the American Fisheries Society, ordinances of the Port of Toledo, and the petition for what would become the Oregon Beach Bill.
Structure-property relationships have always underpinned the field of solid state chemistry; dependable structural descriptions are integral to understanding and controlling the physical properties of inorganic compounds old and new. While a handful of crystal structures are celebrated for their versatility, flexibility, and functionality, the existence of more exotic structures is...
Under-5 mortality has decreased globally, but millions of children still die every year. In Bangladesh, respiratory infection and diarrheal disease remain leading causes of morbidity and mortality for children under-5, despite incredible progress in the past three decades. Immune system development begins in utero and continues into adulthood. Toxic environmental...
