Many nurseries are considering soil moisture sensor networks to improve water application efficiency. Due to
the necessarily wide distribution of sensors at a nursery, a wireless network is easier to install, more flexible, and can be
scaled up as needed without re-design as compared to a traditional wired sensor network....
Despite its widespread use, forest health is frequently used without a clear definition, making its application to forest management difficult. Where the term has been defined (McIntire 1988, Monnig and Byler 1992, USDA Forest Service 1992, USDA Forest Service I993a), alternative definitions and viewpoints of forest health have not been...
Design of a small scale rotating fluidized bed (RFB) with diameter of 4-6 cm to fluidize 40-80 mu m diameter particles was investigated using computational fluid dynamics (CFD). Simulations explored the impact of the following components on pressure drop and fluidized behavior of the device: particle size, particle density, outer...
We present a novel technique to simultaneously measure wind speed (U) at thousands of locations continuously in time based on measurement of velocity-dependent heat transfer from a heated surface. Measuring temperature differences between paired passive and actively heated fiber-optic (AHFO) cables with a distributed temperature sensing system allowed estimation of...
Background Maternal blood total mercury (THg) is a biomarker for prenatal methylmercury (MeHg) exposure. Few studies have quantified both blood THg and MeHg during pregnancy, and few studies have reported longitudinal trends.
Objectives We analyzed blood THg and MeHg in a cohort of pregnant mothers in Charleston, South Carolina (n...
Wildfire greatly impacts the composition and quantity of organic carbon stocks within watersheds. Most methods used to measure the contributions of fire altered organic carbon–i.e. pyrogenic organic carbon (Py-OC) in natural samples are designed to quantify specific fractions such as black carbon or polyaromatic hydrocarbons. In contrast, the CuO oxidation...
Seagrasses and bivalves co-occur worldwide, and each plays a role in the structure, function, and services of coastal ecosystems. While seagrasses are declining, bivalve aquaculture is expanding, and impacts from culture practices, as opposed to the cultured organisms themselves, need to be distinguished. In 2 experiments, we tested the effects...
We compiled a lake-water clarity database using publically available, citizen volunteer observations made between 1938 and 2012 across eight states in the Upper Midwest, USA. Our objectives were to determine (1) whether temporal trends in lake-water clarity existed across this large geographic area and (2) whether trends were related to...
Disturbance regimes differ in type, magnitude, and frequency, but few field experiments have considered compounded effects of disturbance. In this study, we characterized gap recovery after complete removal of eelgrass (Zostera marina) in Willapa Bay, Washington, USA. In separate experiments, we imposed two disturbance types – shoot damage and shoot...
Our study provides a review of theories that were used to study race and racism between 2010 and 2019 in higher education. We conducted a content analysis to identify concepts, statements and models used in higher education studies focused on race and racism in the three most highly read United...
