Cover crop–based organic rotational no-till soybean production has attracted attention from farmers, researchers, and other agricultural professionals because of the ability of this new system to enhance soil conservation, reduce labor requirements, and decrease diesel fuel use compared to traditional organic production. This system is based on the use of(More)
Organic producers in the mid-Atlantic region of the USA are interested in reducing tillage, labor and time requirements for grain production. Cover crop-based, organic rotational no-till grain production is one approach to accomplish these goals. This approach is becoming more viable with advancements in a system for planting crops into cover crop residue(More)
Bacillus spp. and Clostridium spp. form a specialized cell type, called a spore, during a multistep differentiation process that is initiated in response to starvation. Spores are protected by a morphologically complex protein coat. The Bacillus anthracis coat is of particular interest because the spore is the infective particle of anthrax. We determined(More)
We build a general equilibrium model of occupation choice, where the risks inherent in a technology embodying a new innovation are only vaguely known (ambiguous), whereas the old technology has known risks. Using the Arrow-Hurwicz criterion to characterise decision-making in the face of ambiguity, we distinguish agents according to their degree of ambiguity(More)
One of the pitfalls of FPGA design is the relatively long implementation time when compared to alternative architectures, such as CPU, GPU or DSP. This time can be greatly reduced however by using tools that can generate hardware systems in the form of a hardware description language (HDL) from high-level languages such as C, C++, or Python. Such(More)
Entrepreneurs may undertake investments when returns cannot be precisely evaluated: they are decisive. Lenders may require high compensation to place funds in those ventures: they are cautious. We analyze optimal ¯nancing contracts between entrepreneurs and lenders. Decisiveness and cautiousness are characterized using Bewley's (1986) incomplete preferences(More)
HYPOTHESIS Exposure to ciprofloxacin/dexamethasone, but not ofloxacin, prolongs tympanic membrane (TM) healing. BACKGROUND Exposure to hydrocortisone has been shown to delay TM wound healing. No published studies have compared the effects of ciprofloxacin/dexamethasone and ofloxacin on TM healing. METHODS Noninfected TM perforations were created in 30(More)
Using the Farm Energy Analysis Tool (FEAT), we compare energy use and greenhouse gas (GHG) emissions from the cultivation of different crops, highlight the role of sustainable management practices, and discuss the impact of soil nitrous oxide (N 2 O) emissions and the uncertainty associated with denitrification estimates in the northeastern United States.(More)
