"The Only Thing That Is Constant Is Change": A Brief Overview On How Technology Has Changed Futures Markets Part Ii, Fabio Mattos

Cornhusker Economics

In our previous Cornhusker Economics (10/28/2015) we talked about the emergence of electronic trading in futures markets and new trading practices that came with it. In particular, we discussed spoofing and mentioned the trial in Chicago of a trader accused of "poofing" commodity futures markets. As I write this article, a "breaking news" alert, pops up on my computer screen which informs me that the trial is over and the jury has just reached a verdict. As the Financial Times reports, the trader was found guilty on 12 accounts, "Including intending to defraud other traders by flooding gold, corn, soybeans, …

The Founding Of The Robert B. Daugherty Water For Food Institute At The University Of Nebraska

Daugherty Water for Food Global Institute: Administrative Materials

University of Nebraska President J.B. Milliken drove to Omaha in to meet Robert Daugherty at his home. In the living room, the elder Daugherty was surrounded by Mogens Bay, his three sons and a covey of lawyers. Now 88 years old, the businessman had a reputation for being tough-minded and smart, a man who could intimidate, but also surprise with his ready sense of humor. In his long career, Daugherty had transformed agriculture and the rural landscape into the now familiar polka dot pattern, the signature of the center pivot irrigators Daugherty had popularized in the 1970s. He had started …

Vegetable Production Guide For Commercial Growers, 2016-17, Shubin Saha, Emily Pfeufer, Ricardo Bessin, Shawn Wright, John Strang

Agriculture and Natural Resources Publications

Successful vegetable production generally requires the grower to make daily decisions regarding pest management, irrigation, and cultural practices. Would-be growers unwilling to make serious investments of time (and money) should not attempt to expand beyond a space at the farmers’ market. It is important for vegetable growers to have a market outlet for their product before they choose to start production. Good marketing plans start with the customer and work backward to production. Potential growers should first determine exactly what buyers want, how they want it, and when they want it. They then must determine how these crops should be …

Food and Machinery

Norfloxacin, ofloxacin and enorfloxacin, the most common used quinolones in aquaculture, were evaluated for the effects on hemolymph enzymes of Chinese mitten crab, Eriocheir sinensis. The hemolymphs were collected at regular time for detection of phenoloxidase(PO), peroxidase(POD), alkaline phosphatase(ALP), lysozyme(LSZ), superoxide dismutase(SOD), glutamic-oxaloacetic transaminase(AST) and glutamic-pyruvic transaminase(ALT) after Chinese mitten crab were injected intramuscularly with quinolones at concentration of 5 μg/kg. The results showed that activity of PO, POD, ALP, LSZ and SOD increased respectively(P<0.05), and the effect of enorfloxacin experimental group was very obvious(P<0.01), and decreased to the normal levels as the control group at 96 h. The activity of AST and ALT after quinolones injection showed significantly lower during the experimental period(P<0.05). These results indicated that quinolones did not result in inhibition on hemolymph immune enzyme and damage on viscera organs. Moreover, quinolones showed immune enhancement on at concentration of 5 μg/kg.
