The IEA-R1, swimming pool research reactor, from the Institute of Energy and Nuclear Research (IPEN), among other uses, the instrumental neutron activation analysis technique is widely used, and successfully, by the Neutron Activation Laboratory (LAN), using the comparative method. In this method a sample is irradiated simultaneously with a standard. In order to overcome the difficulty of a multi-elementary analysis, because it was necessary to prepare several standards, the k0 method of...

Formulas relating overall sound pressure level (OASPL) to parameters such as horsepower required, tip speed, and thrust for main and tail rotors are presented for standard and quieted helicopters. Formulas relating OASPL to engine parameters such as horsepower output and percent power turbine rpm are presented for unmuffled and muffled engines. The linear scale was used in preference to any of the weighted scales because it resulted in more consistent agreement with the test data when the SPL...

Determination of metal ion contaminants in food samples is studied. A weighed quantity of each sample was digested in a concentrated mixture of nitric, hydrochloric and perchloric acids to affect complete solution of the food products. The samples were diluted with water and the pH adjusted according to the specific analysis performed. The samples were analyzed by neutron activation analysis, polarography, and atomic absorption spectrophotometry. The solid food samples were also analyzed by...

Maralinga is an anomalous CK4 carbonaceous chondrite which contains numerous Ca-, Al-rich inclusions (CAI's) unlike the other members of the CK group. These CAI's are characterized by abundant green hercynitic spinel intergrown with plagioclase and high-Ca clinopyroxene, and a total lack of melilite. Instrumental Neutron Activation Analysis (INAA) was used to further characterize the meteorite, with special focus on the CAI's. High sensitivity INAA was done on eight sample disks about 100-150...

A method has been devised and proven to measure the stable isotope ratio O18/O16, for oxygen, by neutron activation in a fast neutron reactor. The measurement is made non-destructively on a few grams of water with an accuracy of a few parts in ten thousand. At present, measurement to this accuracy requires about 40 minutes with the reactor running at a power of 250 kilowatts, but by increasing detector sensitivity the method promises to become a routine matter accomplished in less time.

Certain characteristics of the neutron field from this unshielded reactor were measured. The activation of gold, manganese, sulfur, cadmium-covered gold, and cadmium-covered manganese was determined as a function of distance from the reactor and of depth in the...

The 1783-1784 Laki tholeiitic basalt fissure eruption in Iceland was one of the greatest atmospheric pollution events of the past 250 years, with widespread effects in the northern hemisphere. The degassing history and volatile budget of this event are determined by measurements of pre-eruption and residual contents of sulfur, chlorine, and fluorine in the products of all phases of the eruption. In fissure eruptions such as Laki, degassing occurs in two stages: by explosive activity or lava...

The solubility of oxygen in tantalum between 600 and 9OOC was determined to be log(ppm 0) =4.130- 1279/TK using a resistivity technique. Carefully reproduced pulses of oxygen were admitted to a high vacuum quartz tube furnace containing a tantalum wire. During each pulse, oxygen was maintained in contact with the specimen for a standard reproduced time after which the oxygen was pumped out and the resistance measured. A plot of change in resistance from the starting value versus number of...

Studies of two potential in vivo neutron activation methods for determining total and partial body nitrogen in animals and humans are described. A method using the CO-11 in the expired air as a measure of nitrogen content was found to be adequate for small animals such as rats, but inadequate for human measurements due to a slow excretion rate. Studies on the method of measuring the induced N-13 in the body show that with further development, this method should be adequate for measuring muscle...

Meta-sediments from Isua, West Greenland were analyzed by instrumental thermal neutron activation analysis (ITNAA). These sediments are chemical precipitates having some layers of remarkably high Cr content. The latter were compared to Cr poor layers. It turned out that the Cr enriched layers had higher Ir and Ni contents than the samples from the Cr poor layers. Compared to phanerozoic samples the highest Ir contents are not extraordinarily higher than in a modern sediment, and the Cr poor...

The anatomical structure and morphology of the oat plant (Avena sativa L.) have been reviewed previously by Hector (1936), Bonnett (1961a,b) and Coffman (1977). In addition, Bonnett published detailed accounts of oat panicle development (1937, 1961a,b). This work has been summarized by Esau in her book, Anatomy of Seed Plants, in 1977. It is not the purpose of the present authors to simply go over all this same material again in a repetitive fashion, but rather, to emphasize some of the more...

Suitable methodology based on neutron activation analysis is developed for accurate measurement of chlorine and bromine from balloon flight sampling. The method is applied to measurement of a number of filter and filter extracts. It is shown that analyses carried out on total filter is inaccurate because of the relatively major filer bank contributions. However, analyses carried out on water extracts of filters appear to yield satisfactory measurements. (Author)

Recent developments of nuclear techniques to measure neutrons and positive ions emitted from pulsed-plasma devices are reviewed. Neutron detection for intensities ranging from 100 to 10 to the 12th power neutrons/pulse is described. Activation detectors are useful for yields exceeding 1,000,000 neutrons. Scintillation detectors are required for less intense yields and for neutron measurements by time-of-flight. Intense pulsed ion beams are measured with nuclear reactions which produce delayed...

The propagation of electron beam currents much greater than the space charge limit and collective ion acceleration in evacuated dielectric guides was investigated. Experiments at Spire and at the Gamble I facility of NRL show that the beam front propagation velocity is not affected by the dielectric guide downstream from the anode region of the accelerator. The propagated current, however, depends strongly on guide parameters, and is considerably diminished in a shortened guide configuration....

Alkalic suite pristine nonmare rocks are distinctly enriched in plagiophile elements such as Na and K, as well as generally incompatible elements, despite modes and textures more characteristic of typical crustal cumulates (most commonly anorthosites) than of the basaltic KREEP rocks that appear to account for the bulk of the lunar crust's total complement of incompatible elements. Our studies indicate that the 77115 troctolitic clasts of Winzer et al. is actually a troctolitic anorthosite (or...

Free-flow electrophoresis was used to study the increase in sample flow rate and sample resolution achievable in space and to separate and analyze biological particles, such as living cells, without decreasing their biological activity. The electrophoresis equipment was designed for the separation of four mixtures of biological cells with variable sample flow rates, buffer flow rates, and electric field gradients. Separation quality was assessed by measuring the light from a quartz lamp through...
