Improving Treatment Outcomes For American Indians With Posttraumatic Stress Disorder Through The Use Of Telepsychaitry

The prevalence of PTSD has increased from 6.8% to 20% since the start of the Covid-19pandemic. For American Indians, the prevalence of PTSD ranged between 16 to 24% prior to the start of the pandemic. American Indians living in rural and tribal communities often experience significant barriers to accessing quality mental health treatment. For these reasons, telepsychiatry is a necessary tool to increase access to care. An entirely home based telepsychiatry program was developed and adapted for PTSD patients within a tribal community and implemented over 12 weeks. 40 patients were engaged at the initiation of the program and a total of 37 remained through the entirety of the program. Patient experiences were assessed based on appointment attendance, the administration of the PCL-5 pre and post program implementation, and patient and staff program evaluations. During the 12 weeks of this program, there was a 4% decrease in patient no shows and rescheduled appointments increased by 23%. Of the 37 patients that completed the program through the 12 weeks, 43% expressed a reduction in PTSD symptoms, 49% saw no change and 8% reported a worsening in PTSD symptoms. Telepsychiatry is a quality treatment delivery method that improves health equity for disadvantaged populations. while also reducing barriers to treatment. Telepsychiatry is comparable to traditional in-person treatment when comparing patient attendance as well as program evaluations. Clinical policies need to address how telepsychiatry can be integrated with in-person care to ensure patients are afforded various options of quality care

Overview: Fluid acquisition and transfer

This brief overview introduced the symposium session on microgravity fluid acquisition and transfer. It states the objective of NASA efforts in this technology and the approach being taken in the technology program. The problems are outlined and various methods for low-gravity fluid acquisition and transfer are summarized. Applications for the technology are described and an assessment of the current state of the art is presented. NASA and DOD on-going and planned programs are listed

Mixing-induced fluid destratification and ullage condensation

In many applications, on-orbit storage and transfer of cryogens will require forced mixing to control tank pressure without direct venting to space. During a no-vent transfer or during operation of a thermodynamic vent system in a cryogen storage tank, pressure control is achieved by circulating cool liquid to the liquid-vapor interface to condense some of the ullage vapor. To measure the pressure and temperature response rates in mixing-induced condensation, an experiment has been developed using Freon 11 to simulate the two-phase behavior of a cryogen. A thin layer at the liquid surface is heated to raise the tank pressure, and then a jet mixer is turned on to circulate the liquid, cool the surface, and reduce the pressure. Many nozzle configurations and flow rates are used. Tank pressure and the temperature profiles in the ullage and the liquid are measured. Initial data from this ground test are shown correlated with normal-gravity and drop-tower dye-mixing data. Pressure collapse times are comparable to the dye-mixing times, whereas the times needed for complete thermal mixing are much longer than the dye-mixing times

Kinetics governing phase separation of nanostructured Sn_xGe_(1–x) alloys

We have studied the dynamic phenomenon of Sn_xGe_(1–x)/Ge phase separation during deposition by molecular beam epitaxy on Ge(001) substrates. Phase separation leads to the formation of direct band gap semiconductor nanowire arrays embedded in Ge oriented along the [001] growth direction. The effect of strain and composition on the periodicity were decoupled by growth on Ge(001) and partially relaxed Si_yGe_(1–y)/Ge(001) virtual substrates. The experimental results are compared with three linear instability models of strained film growth and find good agreement with only one of the models for phase separation during dynamic growth

Nucleate pool boiling in the long duration low gravity environment of the Space Shuttle

The results are presented of an experimental study of nucleate pool boiling performed in the low gravity environment of the space shuttle. Photographic observations of pool boiling in Freon 113 were obtained during the 'Tank Pressure Control Experiment,' flown on the Space Transportation System, STS-43 in August 1991. Nucleate boiling data from large (relative to bubble size) flat heating surfaces (0.1046 by 0.0742 m) was obtained at very low heat fluxes (0.22 to 1.19 kW/sq m). The system pressure and the bulk liquid subcooling varied in the range of 40 to 60 kPa and 3 to 5 C respectively. Thirty-eight boiling tests, each of 10-min duration for a given heat flux, were conducted. Measurements included the heater power, heater surface temperature, the liquid temperature and the system pressure as functions of heating time. Video data of the first 2 min of heating was recorded for each test. In some tests the video clearly shows the inception of boiling and the growth and departure of bubbles from the surface during the first 2 min of heating. In the absence of video data, the heater temperature variation during heating shows the inception of boiling and stable nucleate boiling. During the stable nucleate boiling, the wall superheat varied between 2.8 to 3.8 C for heat fluxes in the range of 0.95 to 1.19 kW/sq m. The wall superheat at the inception of boiling varied between 2 to 13 C

The subscale orbital fluid transfer experiment

The Subscale Orbital Fluid Transfer Experiment (SOFTE) is a planned Shuttle Orbiter fluid transfer experiment. CASP (Center for Advanced Space Propulsion) performed certain aspects of the conceptual design of this experiment. The CASP work consisted of the conceptual design of the optical system, the search for alternative experimental fluids, the determination of the flow meter specifications and the examination of materials to use for a bladder that will empty one of the tanks in the experiment

Spectral investigation of the molecular vibration region of single crystalline potassium sulfate

A spectral investigation of the molecular vibration region of the potassium sulfate crystal system was undertaken. This study was initiated to establish the feasibility of using this crystal as a host matrix for ammonium sulfate. Since these two systems are isomorphic and have unit cells of nearly equal volume the ammonium ion can be studied in a surrounding similar to that of the ammonium sulfate crystal with a variable degree of inter-ion coupling by doping the potassium sulfate crystal with different amounts of ammonium sulfate. The potassium sulfate vibration region was characterized, by infrared transmission and reflection measurements plus laser Raman scattering. A technique incorporating a reflection goniometer was used to identify the habit of laboratory grown potassium sulfate crystals and to guide the preparation of faces perpendicular to each of the three principle axis. Spectra invoking polarized radiation were subsequently obtained from these faces and band assignments made on the basis of a correlation diagram. Preliminary transmission investigations of ammonium doped potassium sulfate gave excellent results establishing the feasibility of this approach
