Relational memory theory holds that the hippocampus supports, and amnesia following hippocampal damage impairs, memory for all manner of relations. Unfortunately, many studies of hippocampal-dependent memory have either examined only a single type of relational memory or conflated multiple kinds of relations. The experiments reported here employed a procedure in which each of several kinds of r...

An outdoor experiment was set up to investigate the effects of used lubricating oil (5 L/m2) on Aegiceras corniculatum Blanco. and Avicennia marina (Forsk) Vierh., two salt-excreting mangroves. A. marina was more sensitive to used lubricating oil than A. corniculatum and canopy-oiling resulted in more direct physical damage and stronger lethal effects than base-oiling. When treated with canopy-...

Sleeve and large field cage experiments were conducted in Stoneville, MS, in 2010 and 2011 to assess adult rice stink bug, Oebalus pugnax (F.), injury in rice. 'Cocodrie' and 'Wells' were infested at bloom, milk, and soft dough stages of panicle development. Twenty rice panicles were infested individually in the sleeve cage experiment as replicates with 0, 1, or 2 O. pugnax in a split-plot, com...

It is proposed to identify damage variables and their growth with loading in two dimensions by only using full-field displacement measurements. The equilibrium gap method is used to estimate the damage field during a biaxial experiment on a sample made of a composite material. From the analysis of a sequence of measurements, a proposed form of constitutive law is tested and identified. The emph...

Exposure to DNA-damaging agents invokes biological responses necessary for damage recovery and cell survival. Despite the presence of intact DNA repair pathways, lack of certain other biological pathways has been shown to sensitize cells to DNA-damaging agents’ exposure. It is likely that following DNA damage a complex interplay between DNA repair pathways and other biological pathways might be...

Plant tolerance to natural enemy damage is a defense strategy that minimizes the effects of damage on fitness. Despite the apparent benefits of tolerance, many populations exhibit intermediate levels of tolerance, indicating that constraints on the evolution of tolerance are likely. In a field experiment with the ivyleaf morning glory, costs of tolerance to deer herbivory in the form of negativ...

1. Plants are known to respond to damage with subsequent changes in resistance. The consequences of these changes for plant fitness and herbivore populations will depend on both the response of a plant to a particular attack at a given moment and on how plants respond through time to varying levels of damage and varying numbers of attacks. While a small number of studies document how induced re...

Through a recently conducted rat-tail vibration experiment, we have been able to determine that the tested frequencies of vibration have a significant effect on biochemical damage signified by nitro-tyrosine (NT) staining on trabecular bone, while structural damage quantified through a Hematoxylin and Eosin (H&E) stain on cortical bone exhibited statistical significance only for the 250 Hz grou...
