Conducting polymers such as polypyrrole may be useful in smart packaging products, provided application methods can be developed that circumvent the insolubility and infusibility of these materials. Experiments were conducted in five research areas relevant to the application of polypyrrole to nonrigid substrates. The studies reveal that application of polypyrrole from the liquid phase, either by deposition from depleted bulk solution or inkjet printing dispersions, is unlikely to give films as regular as those produced by vapor phase polymerization. Using the latter approach, two potential methods of applying patterned polypyrrole films to nonrigid substrates were developed. The first used hypochlorite to pattern a continuous film of polypyrrole, previously applied by vapor phase polymerization. The second used inkjet printing to apply an oxidant solution, whose pH had been raised with a volatile base, to nonrigid substrates. The higher pH reduced corrosion of the print head, increasing the lifetime of printers exposed to oxidative compounds. The base was subsequently evaporated by heating, and the dried oxidant used as a template for vapor phase polymerization of polypyrrole. This method gave smooth, shiny and adherent polypyrrole films on papers and polyester transparency, with high resolution. © 2007 Wiley Periodicals, Inc. J Appl Polym Sci 104: 3938–3947, 2007

A database and an application, known as “NUCLEIDE”, have been developed with the aim of offering users easy access to nuclear and atomic decay data simply by clicking on buttons. The aim of this table is to provide recommended data for nuclides of special interest for metrology or practical applications, such as nuclear medicine, monitoring and reactor shielding, etc. Primary recommended data comprise half-lives, decay modes, branching fractions and their uncertainties and the energies and emission intensities for X-and gamma-rays, electron emissions and alpha particles. In order to update the data and regularly add new evaluations, a new international collaboration has been formed, the Decay Data Evaluation Project (DDEP), comprising evaluators from Prance, Russia, Germany, United Kingdom, Spain and the United States. Its objective is to provide carefully recommended values which may eventually become standard data. The results of this work are available on CD-ROM or in print.

The relative full-energy peak efficiency curve of a 280-cm3 coaxial HPGe detector was determined to an accuracy of about 0.1% over the energy range from 433 to 2754 keV from pairs of gamma-ray lines whose emission probabilities are very accurately known. The curve was extended from previous studies by the addition of lines from 108 m Ag and 24 Na . Ratios of full- energy peak efficiencies were also determined by Monte Carlo calculations using the CYLTRAN code. The measured ratios and the Monte Carlo values were in excellent agreement (0.03–0.19%). The relative efficiency was defined by a pair of functions, one for 433–1332 and one for 614–2754 keV. Monte Carlo values were used to supplement the measured values, resulting in a more accurate fit. The stability of the relative efficiency curve for a 94-cm3 HPGe detector was studied and it was found that there was no statistically significant change over a period of 3 years.

The possibility of using the video superimposition technique for the identification of a skull by comparing it with photographs of missing persons is founded on the fact that the human skull, unlike any other part of the human skeleton, shows unmistakable individual characteristics. In order to obtain a quantification, the individuality of human skulls is defined in terms of craniometric data and their probability distribution. First calculations based on the coordinates of some important encephalometric points of 52 European skulls suggest individualities comparable to those of fingerprints. Under certain conditions the video superimposition technique can establish very strong evidence for the identity of an unknown skull, provided that it is applied correctly and carefully.

A patient with sickle cell anemia was hospitalized because of an acute erythropoietic aplastic crisis. 111In chloride bone marrow scintigraphy performed during the aplastic crisis showed markedly impaired uptake of the radionuclide and simultaneous 59Fe clearance T 1/2 studies were prolonged (420.9 min). Following recovery from the aplastic crisis 111In scintigraphy revealed an expanded marrow and the radioiron clearance T 1/2 was accelerated (20.9 min). The clinical course, hemograms and bone marrow aspirations correlated with marrow scintigraphy. 111In appears to be a valuable marrow scanning agent for assessing the presence of intramedullary erythropoietic activity.

A 28 year old white man with hemophilia A had, for several years, been successfully maintained on a home care program utilizing self-administration of factor VIII concentrates, but one such infusion resulted in severe anaphylaxis. An immunoglobulin E (IgE)-mediated hypersensitivity response was demonstrated by (1) the release of histamine from the patient's basophils in vitro upon challenge with several different lots of factor VIII concentrate; (2) immediate cutaneous response to commercial factor VIII, factor IX and cryoprecipitate; and (3) measurement of IgE antibodies against a commercial factor VIII preparation. A subsequent life-threatening hemorrhage required cautious infusion of another commercial lot of factor VIII concentrate. Despite pretreatment with antiallergic drugs and attempted desensitization, a moderately severe anaphylactic reaction was observed.

The logic underlying the Box-Jenkins transfer function analysis is developed and compared with established econometric approaches. The technique is shown to provide a safeguard against spurious effects by eliminating all time dependency in the data before assigning any effects to proposed independent variables, and by the systematic elimination of a wide variety of candidate effect models. The procedural steps in the technique are demonstrated in an application to the advertising-sales relationship, with particular focus on the advertising lag structure. The two best Box-Jenkins models are compared with previously derived advertising effect models and are shown to have greater forecasting accuracy.

The report contains production guides for meat entree items developed specifically for use in the Fort Lee Interim Central Food Preparation Facility. The entrees, selected from a 21-day menu developed by Fort Lee and Natick Laboratories personnel, are described in terms of ingredients, and weight of each, and the procedures for their preparation. Tempering procedures are described and also the requirements for reheating times and temperatures. By adhering to the guidelines for reheating as given in the individual production guides, satisfactory results can be predicted. Extensive testing was conducted, followed by numerous reformulations. A principal goal was to streamline the cooking process in order that institutional type machinery could be used.

Production guides are given for meat and vegetable entrees, as well as desserts. The guides are designed for use in the Frozen Foil Pack Meal Feeding System at F.E. Warren Air Force Base. Procedures are described for the preparation of 100 portions of each of the designated items. Changes in formulation and evaluation of finished products are the result of extensive work at NRDC. The objective was to make it possible to use institutional type facilities. It is recommended that production procedures, especially critical control points as well as procedures, be followed closely in order to obtain a safe and high quality product.

Since the introduction of digital computer techniques to lens design more than a decade ago, steady progress has been made in auto-mating, or partially automating, this conceptual process.© (1966) COPYRIGHT SPIE--The International Society for Optical Engineering.

In 1985 at the cemetery in Embu near Sao Paulo, Brazil, parts of a skeleton were exhumed, and now these parts have been examined to determine whether they are the remains of the corpse of Dr. Josef Mengele, the camp doctor of the Auschwitz concentration camp. The osteometrical and osteological findings ascertained correspond completely and consistently without contradiction with all the available personal data of Josef Mengele. Through a method of electronic visual mixing for the identification of the skull, it was determined that all the authentic pictures available used for comparison correspond definitely and consistently to the exhumed skull.
