This paper focuses on the small-signal stability of power system integrated with DFIG-based wind farm. The model of DFIG for small-signal stability analysis has built; the 3-generator 9-bus WECC test system is modified to investigate the impacts of large scale integration of wind power on power system small-signal stability. Different oscillatory modes are obtained with their eigenvalue, freque...

Structural change in the US dairy industry toward fewer and very large farms has fueled interest and government funding of research into the feasibility of constructing anaerobic digesters (ADs) on large operations as a waste management strategy. Some groups opposed to increasing scale and concentration in the livestock sectors, including dairy, also oppose ADs because of the connection with la...

INTRODUCTION Schools are uniquely positioned to influence the dietary habits of children, and farm-to-school programs can increase fruit and vegetable consumption among school-aged children. We assessed the feasibility of, interest in, and barriers to implementing farm-to-school activities in 7 school districts in Douglas County, Nebraska. METHODS We used a preassessment and postassessment su...

Relationships between Payments Received and Farm Household Well-Being Government payments to farmers increased from about $7.5 billion in 1996—the year the “Freedom to Farm” bill was enacted—to over $20 billion in 1999, 2000, and 2001. This increase stemmed from a drop in agricultural prices, which spurred a dramatic growth in emergency market assistance payments and loan deficiency payments (s...

Antimicrobial resistance (AMR) in humans is inter-linked with AMR in other populations, especially farm animals, and in the wider environment. The relatively few bacterial species that cause disease in humans, and are the targets of antibiotic treatment, constitute a tiny subset of the overall diversity of bacteria that includes the gut microbiota and vast numbers in the soil. However, resistan...
