Year: 2014 Pacific Spaceflight’s Mark II pressure garment (model Gagarin) was test flown to 17,200 feet MSL (5,242m) while worn and operated by Dr. C.M. Smith. The garment and its portable life support system (PLSS) maintained appropriate pressure, temperature and carbon dioxide levels throughout the 47-minute flight. The suit also provided sufficient elbow mobility, due to its convolute joints, for the suited person to operate the portable life support system’s manual suit pressure setting valve and the hand-held radio.

• 242. [Article] Thermal hysteresis in acoustic resonators

  In some applications of piezoelectrically driven acoustic resonators, the power dissipated in the resonating material may be sufficient to significantly change the temperature and hence the resonance frequency. ...

Year: 1982 In some applications of piezoelectrically driven acoustic resonators, the power dissipated in the resonating material may be sufficient to significantly change the temperature and hence the resonance frequency. A straightforward analysis shows that this effect can lead to severe hysteresis and thermal bistability. This model is in agreement with experiments that have been performed using a fused silica acousto‐optic modulator.

  Citation × Citation Citation Abstract Copy Title: Residual images in charged-coupled device detectors Author: Rest, Armin, Mündermann, Lars, Widenhorn, Ralf, Bodegom, Erik, McGlinn, T. C. Year: 2002 We present results of a systematic study of persistent, or residual, images that occur in charged-coupled device (CCD) detectors. A phenomenological model for these residual images, also known as "ghosting," is introduced. This model relates the excess dark current in a CCD after exposure to the number of filled impurity sites which is tested for various temperatures and exposure times. We experimentally derive values for the cross section, density, and characteristic energy of the impurity sites responsible for the residual images.

Year: 2014 We provide an estimate of the cross section for the radiative attachment of a second positron into the state of the ion using Ohmura and Ohmura's (1960 Phys. Rev. 118 154) effective range theory and the principle of detailed balance. The ion can potentially be created using interactions of positrons with trapped antihydrogen, and our analysis includes a discussion in which estimates of production rates are given. Motivations to produce include its potential use as an intermediary to cool antihydrogen to ultra-cold (sub-mK) temperatures for a variety of studies, including spectroscopy and probing the gravitational interaction of the anti-atom.

• 246. [Article] Calculating Compound Dependent Gas-Droplet Distributions in Aerosols of Propylene Glycol and Glycerol from Electronic Cigarettes

  Citation × Citation Citation Abstract Copy Title: Calculating Compound Dependent Gas-Droplet Distributions in Aerosols of Propylene Glycol and Glycerol from Electronic Cigarettes Author: Pankow, James F. Year: 2017 Aerosols created by electronic cigarettes are suspensions of liquid droplets in a gas phase. All of the volatile or semi-volatile compounds in the system will partition between the two phases. Among these compounds are the “e-liquid” constituents plus the degradation products such as formaldehyde produced during “vaping”. This partitioning affects deposition in the respiratory tract and optimal analytical method design. Theory can be used to predict the particle-gas distribution of each compound as a function of the mass concentration of the aerosol droplets (μg/m3), the composition of the droplets, temperature, and the vapor pressure of the compound. As an example, even at the highest total particulate matter (TPM, µg/m3) levels for e-cigarette aerosols, formaldehyde as CH2O will be mostly in the gas phase; two important adducts of formaldehyde will be mostly in the aerosol droplets even at the lowest TPM levels.

The chromium oxide trifluoride is produced as crystals which are suitable for single crystal studies. In reactions of chromium oxide trifluoride with alkali and alkaline metal fluorides in anhydrous hydrogen fluoride, new chromium(V) oxide fluoride salts were obtained; these salts were not of high purity due to unknown problems. An attempt to prepare chromium oxide tetrafluoride by the reaction of xenon difluoride with chromyl fluoride in anhydrous hydrogen fluoride failed to produce the desired product.

  Citation × Citation Citation Abstract Copy Title: Aspects of cardiovascular oxygen transport in vertebrates Author: Hedrick, Michael Scott Year: 1985 The hematological and rheological characteristics of blood from a number of vertebrates was compared to assess possible species differences in blood viscosity that may influence cardiovascular oxygen transport. Nucleated red blood cells (RBCs) were more viscous (measured by cone-plate viscometry) in comparison with enucleate (mammalian) RBCs at hematocrits greater than 40% when measured at equivalent temperatures. The lower viscosity of enucleate RBCs is attributed to an enhanced deformability of enucleate cells in comparison to nucleated cells.

Data was collected to determine if the well is under direct influence by surface water. Direct influence and the extent of the correlation was determined by statistically analyzing the well turbidity with surface water flow and temperature variability. The surface water flow and was lagged per period and with a weighted average to determine the highest correlation. Logistic regression models were developed to determine if a predictive model can predict permit conditions based on the data collected.
