Antibody to influenza infection was determined by counterimmunoelectrophoresis (CIE). The antibody resulting from influenza disease reacted to both related and distant strains of influenza A antigen but not to influenza B antigen. CIE antibody was not demonstrable following immunizations with inactivated influenza vaccine. While influenza antibody, as demonstrated by CIE, was always associated with elevated complement fixation antibody, the reverse was not the case. Since the precipitating...

Today's industrial control systems (ICS) environments are incredibly complex assemblages of technology, processes, and people that work together to successfully carry out the missions and business functions of an organization. These systems have improved water and wastewater service and increased reliability in those infrastructures. As ICS have become more affordable and easier to use, most utilities have chosen to adopt them for process monitoring and/or control. This reliance on ICS has left...

Food Allergies occur in 2-6% of children in the United States. The reactions can be mild to severe and life threatening and potential fatal. No study has been able to identify genetic causes of IgE mediated food allergies. In our previous work, we identified polymorphism in thymic stromal lymphopoietitin region as risk factor for Eosinophilic Esophagitis, a non-IgE mediated disease. This work has examined the genetics of food allergy looking at both IgE and non-IgE mediated food allergy using...

Following the U.S. invasions of Iraq and Afghanistan, the Iranian threat to U.S. interests has taken on seemingly unprecedented qualities of aggressiveness and urgency. Added to its provocative positions on the nuclear program, support for non-state militants, and development of threatening military capabilities is the sense that Iran is trying to effect far-reaching changes on the regional and even global stage. Within this context, this report aims to provide policy planners with a new...

After landing on the beaches of Normandy during World War II, the Allies needed means to move necessary equipment over the secured beachhead and to the front lines. The answer was the Mulberry Harbor. A modern concept design of the harbor has been undertaken to overcome the limitations of the original design and meet new operating requirements. The Mulberry 21 design will be fast to deploy, easily recovered, and able to survive in higher sea states. The harbor system consists of an elevated...

Recently, Congress, the literary community, and the public at large have come to reconsider the war on drugs. There are many opinions regarding alternatives to this pseudo war or new measures to be taken in the war effort, but the ongoing effort itself has escaped evaluation (to determine if the United States is winning this campaign). The intent of this thesis, then, is to explore the objectives of the war on drugs, and to determine if America is winning. This work concludes that the current...

In a tailored test, each item is selected for administration on the basis of the examinee's responses to previous items, with a view towards optimum measurement of this particular examinee. Various simple rules for (1) selecting the items to be administered and (2) scoring the examinee's responses are compared and evaluated. Some fundamental ideas emerge that will serve as guides in the future design of tailored testing programs.

The failure modes and dislocation substructure produced by fatigue crack propagation at 593 C in fast neutron irradiated and unirradiated Type 316 stainless steel were studied.

The results are consistent with the activation of either grain...

In this paper we obtain the sampling properties of a scale-free estimator of 'redundancy,' an information theoretic measure, which is used by economists and communications engineers. We then propose a new test of exponentiality based upon the sample redundancy. This test is unbiased against a large class of alternatives, and it performs at least as well as another recently proposed test with respect to power and asymptotic relative efficiency. (Author)
