Genetic diversity of populations of Astragalus oniciformis using inter-simple sequence repeat (ISSR) markers

Creator:: Alexander, J. Andrew
Abstract:: Astragalus oniciformis Barneby is a xerophyte of the sagebrush deserts of central Idaho. It is a narrow endemic of the upper Snake River Plains where it inhabits stabilized, aeolian sand deposits over Quaternary basalt flows. The objective of this study was to determine the levels and distribution of genetic differentiation...

The toxicogenetic effects of a chitosan based hemostatic control patch in rat models

Creator:: Colburn, Andrew J.
Abstract:: Chitosan based hemorrhage control dressings provide effective external hemorrhage control while having few side effects. Known residual contaminants present in chitosan formulations include endotoxins and proteins known to stimulate gene expression in the liver. This study investigated gene expression in the liver using rat bio-compatibility models to gain knowledge regarding...

Zeolite packed biologically active filter (biofilter) to reduce odorous emissions from a confined swine building

Creator:: Stoeckinger, Andrew J.
Abstract:: A zeolite packed biofilter was retrofitted to a confined swine feeding operation in Eastern Washington, and evaluated for its ability to reduce the malodors from fan exhaust drawn from an internal under-slat manure storage pit. Ammonia (NH₃) was used as the representative constituent of swine waste malodor due to its...

A taxonomic revision of Astragalus mokiacensis and allied taxa within the Astragalus lentiginosus complex of Section Diphysi

Creator:: Alexander, J. Andrew
Abstract:: North America, with over 400 species of Astragalus (Fabaceae), is one of three major centers of diversity, all of which comprise the majority of the nearly 1750 species of Astragalus worldwide. One of the most diverse species, Astragalus lentiginosus of Section Diphysi, is a polymorphic complex of over 40 varieties,...

You Can’t Beat the Clock: Oxidative Stress and period Mutants in Drosophila melanogaster

Creator:: Davis, Andrew J.
Abstract:: The free-radical theory of aging proposes that intracellular accumulation of oxidative damage caused by reactive oxygen species (ROS) is responsible for the process of senescence. ROS are produced during normal aerobic metabolism and have been shown to cause numerous cellular and sub-cellular defects that lead to termination of the cell...

Refinements to Ice Particle Mass Dimensional and Terminal Velocity Relationships for Ice Clouds. Part I: Temperature Dependence

Creator:: Heymsfield, Andrew J., Bansemer, Aaron, and Twohy, Cynthia
Abstract:: This two-part study attempts to find appropriate mass dimension and terminal velocity relationships that, when considered together with particle size distributions (PSD), agree with coincident measurements of ice water content (IWC), and with variables related to higher moments such as the mean mass-weighted fall speed. Reliable relationships are required for...

Optimally managing a stochastic renewable resource under general economic conditions

Creator:: McGough, Bruce, Plantinga, Andrew J., and Costello, Christopher
Abstract:: Empirical evidence indicates that environmental fluctuations have important effects on fisheries production. However, existing analytical solutions of stochastic fisheries models have been produced only under highly simplified economic and biological conditions. The main contribution of this paper is to derive under general conditions a policy function for the management of...

Genetic diversity of the narrow endemic Astragalus oniciformis (Fabaceae)

Creator:: Alexander, J. Andrew, Liston, Aaron, and Popovich, Steve J.
Abstract:: Astragalus oniciformis Barneby is a narrow endemic xerophyte of the upper Snake River Plain of central Idaho, USA, where it inhabits stabilized, aeolian sand deposits and previously burned, sandy sites over Quaternary basalt flows. The objective of this study was to determine the levels and distribution of genetic differentiation within...

Theoretical derivation of the depth average of remotely sensed optical parameters

Creator:: Zaneveld, J. Ronald V., Barnard, Andrew H., and Boss, Emmanuel
Abstract:: The dependence of the reflectance at the surface on the vertical structure of optical parameters is derived from first principles. It is shown that the depth dependence is a function of the derivative of the round trip attenuation of the downwelling and backscattered light. Previously the depth dependence was usually...

Influence of surface waves on measured and modeled irradiance profiles

Creator:: Zaneveld, J. Ronald V., Boss, Emmanuel, and Barnard, Andrew
Abstract:: Classical radiative transfer programs are based on the plane-parallel assumption. We show that the Gershun equation is valid if the irradiance is averaged over a sufficiently large area. We show that the equation is invalid for horizontal areas of the order of tens of meters in which horizontal gradients of...
