Reductive sulfate assimilation, the biological process by which sulfur-containing amino acids and key derivatives are synthesized from sulfate, is broadly shared among bacteria, fungi, and plants. It is the major, if not sole source of methionine and cysteine for Saccharomyces cerevisiae during wine fermentation. Two obligate intermediates formed in the...
Within The Lamplighter, a novel written in 1854, Maria
Susanna Cummins defines a version of the sentimental novel
that significantly differs from the prescriptive analysis
male critics have offered for the genre. This thesis
argues that feminist theory and recent rhetorical theory
have caused a critical paradigm shift that has...
Phaseolus vulgaris, the common bean, is susceptible to many
bacterial, fungal and viral diseases. However, resistance to several
diseases has been identified in related Phaseolus species, P.
coccineus, P. acutifolius and P. lunatus. Thus, interspecific
hybridization could result in transfer of beneficial characteristics.
One of the problems encountered in interspecific...
Pseudo-Nitzschia (P/N) is a species of naturally occurring phytoplankton that contributes to harmful algal blooms (HABs) in the California Current System (CCS). P/N can produce domoic acid (DA), a toxin which accumulates in organisms that consume phytoplankton, leading to amnesiac shellfish poisoning in higher trophic levels. Thus DA can negatively...
This work is concerned with determining whether nicotine has a role in promoting oxidative damage in human tissue, particularly in lung tissue. This follows from recent reports of a novel lung disease found in some E-cigarette users, characterized by oxidative damage and elevated levels of neutrophils (termed “vaping disease”). It...
Evaporation synergy is a phenomenon that occurs between different classes of soil and allows for a greater amount/quantity of soil water evaporation. 20 of the 66 soil texture class combinations have been shown to exhibit evaporation synergy (Fisher, 2012), however the impact of column width on the functionality of this...
Engineered capillary barriers typically consist of two layers of granular materials designed so that the contrast in sediment hydrologic properties and sloping interface retains infiltrating water in the upper layer. We report here on the results of two bench-top capillary barrier experiments, and associated modeling. These experiments were conducted to...
Common root rot is a major disease of commercially grown snap bean (Phaseolus vulgaris L.) on the irrigated sandy soils of central Wisconsin. The objective of this study was to determine the relationships between soil properties and suppressiveness to common root rot of snap bean (causal agent Aphanomyces euteiches) in...
The regulation of behavior is a major issue in early childhood development, with important implications for children’s adaptive and maladaptive developmental outcomes. Emerging research suggests that the degree of successful self-regulation depends upon the efficiency of the child’s attentional system and that the ability to focus and sustain attention supports...
Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....
