Coastal Carolina University, commonly referred to as CCU or Coastal, is a public, state-supported, liberal arts university in Conway, South Carolina, USA, located eight miles west of Myrtle Beach. Founded in 1954, Coastal became an independent university in 1993.The university is a national sea-grant institution and owns part of Waties Island, a 1,105-acre barrier island which serves as a natural laboratory. Coastal Carolina is also the home of the Horry County Schools Scholars Academy, a high school for gifted students. Wikipedia.

We present a phenomenological model for the photocurrent transient relaxation observed in ZnO-based metal-semiconductor-metal (MSM) planar photodetector devices based on time-resolved surface band bending. Surface band bending decreases during illumination, due to migration of photogenerated holes to the surface. Immediately after turning off illumination, conduction-band electrons must overcome a relatively low energy barrier to recombine with photogenerated holes at the surface; however, with increasing time, the adsorption of oxygen at the surface or electron trapping in the depletion region increases band bending, resulting in an increased bulk/surface energy barrier that slows the transport of photogenerated electrons. We present a complex rate equation based on thermionic transition of charge carriers to and from the surface and numerically fit this model to transient photocurrent measurements of several MSM planar ZnO photodetectors at variable temperature. Fitting parameters are found to be consistent with measured values in the literature. An understanding of the mechanism for persistent photoconductivity could lead to mitigation in future device applications. Source

Background Despite selenium's toxicity in plants at higher levels, crops supply most of the essential dietary selenium in humans. In plants, inorganic selenium can be assimilated into selenocysteine, which can replace cysteine in proteins. Selenium toxicity in plants has been attributed to the formation of non-specific selenoproteins. However, this paradigm can be challenged now that there is increasingly abundant evidence suggesting that selenium-induced oxidative stress also contributes to toxicity in plants. Scope This Botanical Briefing summarizes the evidence indicating that selenium toxicity in plants is attributable to both the accumulation of non-specific selenoproteins and selenium-induced oxidative stress. Evidence is also presented to substantiate the claim that inadvertent selenocysteine replacement probably impairs or misfolds proteins, which supports the malformed selenoprotein hypothesis. The possible physiological ramifications of selenoproteins and selenium-induced oxidative stress are discussed. Conclusions Malformed selenoproteins and oxidative stress are two distinct types of stress that drive selenium toxicity in plants and could impact cellular processes in plants that have yet to be thoroughly explored. Although challenging, deciphering whether the extent of selenium toxicity in plants is imparted by selenoproteins or oxidative stress could be helpful in the development of crops with fortified levels of selenium. © 2013 The Author.

The use of computer-mediated communication continues to increase dramatically in organizations, bringing with it new avenues for sexual harassment. Despite the recognition that cybersexual harassment is an important phenomenon and that the online behaviors of employees can adversely affect the organization, there is little research on the development of instruments to measure related constructs. In the present study, scales are created to measure perceptions of the online environment that are thought to precipitate the occurrence of harassment and intentions to engage in sexually harassing behavior. It is found that perceptions of the online environment as stimulating (where risk taking is exhilarating), and as an environment in which blatant prejudice is acceptable, are related to multiple forms of cybersexual harassment. © 2013 International Communication Association.

Abrupt centennial-to-millennial shifts in Northern Hemisphere climate during the last deglaciation are thought to have been triggered by the discharge of large volumes of meltwater and icebergs to the subpolar North Atlantic1. Here we show that meltwater and icebergswere also transported directly fromthe Laurentide ice margin to the subtropical NorthAtlantic in a narrow coastal current. We present high-resolution bathymetric data from south of Cape Hatteras showing numerous scours that we interpret as relict iceberg keel marks. This indicates that icebergs up to 300m thick drifted to southern Florida (24.5° N). In simulations with an ocean circulation model, during deglaciation, freshwater and icebergs routinely reached as far south as 32.5° N, in a period of less than four months. The southernmost scours formed only during periods of high meltwater discharge fromthe Northern Hemisphere ice sheets. In the simulations, such extreme periods of meltwater release led to a reversal of the typically northward surface flow in the nearshore subtropical western North Atlantic. We therefore suggest that significant volumes of iceberg-laden meltwater routinely bypassed subpolar regions and spread across the subtropical North Atlantic. © 2014 Macmillan Publishers Limited.
