The measurement and interpretation of ion bombardment energies in rf discharges SF6, CF3Cl, CF3Br from 0.2 to 1.0 Torr, are discussed. Errors sampling due disturbances the electric field neutral density around orifice shown be most important at higher pressures with larger orifices. dependence energy distribution on electric-field-to-pressure ratio is reviewed. Combining this relation a simple electrical model plasma gives estimates collisional sheaths. proportional (rf current)/(electrode...
Atomic chlorine concentrations in Cl2 and CF3Cl plasmas have been measured using both infrared absorption spectroscopy optical emission actinometry. These measurements were made over a range of plasma conditions including excitation frequencies 72 kHz–13.5 MHz, power inputs 10–100 W, pressures 200–800 mTorr. In plasmas, the technique actinometry misrepresents atomic concentration changes by nearly an order magnitude. The errors are believed to result from excited state Cl production electron...
A parallel plate plasma etching apparatus with extensive diagnostic capabilities has been constructed to study the of heavily P‐doped polysilicon in Freon® 13 mixtures. simple ac impedance model was used estimate time‐averaged properties; this gave electron densities and sheath voltages reasonable agreement experimental evidence. Response surface methodology, an design statistical analysis tool, efficiently obtain high quality empirical representations rate total ion flux as functions...
Gay, lesbian, bisexual, transgender, and queer/questioning (GLBTQ) youth face oppression despite some increases in cultural support for GLBTQ individuals. Research has revealed the psychological social distress associated with benefits of peer programs. This study was conducted to analyze types frequency services, age participants, organizational structures 116 community-based programs operating United States. Using an Internet survey, information from 61 secured. The results provide...
There has been recent increase of interest among radiologists in protraction multiple roentgen doses (fractionation) the treatment cancer. This generated part by Strandqvist's<sup>1</sup>study this subject skin cancer and Andrews'<sup>2</sup>and Ahlbom's<sup>3</sup>papers discussing Strandqvist's work. We have noticed a gap teaching on that we believe should be filled. is failure to stress importance size field irradiated as related maximum dose (fractionated or massive) can give good...
Psychosocial stressors related to the coronavirus-19 (COVID-19) pandemic increased alcohol consumption. The effect on patients with alcohol-related liver diseases remains unclear.Hospitalizations at a tertiary care center due disease from March 1 through August 31 in 2019 (pre-pandemic cohort) and 2020 (pandemic were reviewed retrospectively. Differences patient demographics, features, outcomes estimated alcoholic hepatitis utilizing T-tests, Mann-Whitney tests, Chi-square Fisher Exact Tests...
Three kinetic models, based on experimentally measured and theoretically estimated plasma properties, are developed to describe heavily P‐doped polysilicon etching in (Freon® 13) RF discharges. The models include both chemical ion‐assisted processes, and, therefore, predict directionality as well rate. results indicate the importance of relatively low energy (<30 eV) ion bombardment, suggest that dominant loss process for etchant is diffusion‐limited recombination at electrode surfaces....
The equilibrium deposition efficiency and the chemical potential driving force for nucleation and/or of silicon from gaseous Si‐Cl‐H system are presented a wide range compositions temperatures. Chlorine addition lowers thermodynamic nucleation, as well efficiency. In addition, buffering effect is observed, which potentially could be exploited to improve uniformity CVD processes. Possible applications these results thin film polysilicon production in free‐space fluidized bed reactors discussed.
Limited data exists on the temporal trend of Sars-CoV-2 immunologic response and duration protection following natural infection. We sought to investigate presence serum antibodies in obstetrical healthcare workers (HCW) serial assessments over a 6-month period, assess rates vaccine acceptance reported side effects among this cohort.
UROLOGISTS and radiologists have recognized for years that irritation of the urinary tract seemed to cause intestinal gas appear in urograms; patients with ureteral or kidney pelvis stones, pyelitis, catheters place suffered from meteorism. Few published articles on this subject. A review recent medical literature yields little no proof does presence tract, though most authors imply it meteorism, distention, flatus. Few, if any, state whether meteorism means stomach, small intestine, colon,...
Due to several high profile suicides and increased social acceptance of lesbian, gay, bisexual, transgender, queer/questioning (LGBTQ) persons in the United States, significant media attention has focused on occurrence factors that contribute sexual gender minority youth (SGMY) suicide. Although previous research established an likelihood suicidal ideation among SGMY, no data exist completed SGMY States or subsequent coverage. This study examines variables related from written electronic (N...
Introduction A REVIEW of the available American and some foreign literature has failed to disclose a reference method determining, from roentgenogram itself, degree inspiration at which radiograph chest is made. An x-ray examination co-operative patient assures known phase respiration if proper radiographic technic used. However, in younger children unco-operative adults, must be determined plates. It purpose this paper show that knowledge vital interpretation lung-fields, especially...
SIX months ago it was determined to investigate some phases of post-operative chest complications by means X-ray examination. The practice making bedside examinations before and after operation begun. To date, the series cases which have been radiated includes high low abdominal operations, herniotomies, kidney thyroid perineal repair, curettements, hemorrhoidectomies, one submucous resection, two radium applied cervix uteri, breast amputations, operations upon feet. anesthetics given this...
An experimental technique for measuring total positive‐ion‐bombardment fluxes and energy distribution is presented. It shown that mean ion energies in (Freon® 13) plasmas can be well described by discharge electrical impedance analysis conjunction with a simple sheath transport model. Based on the measurement of only rms current, are predicted. empirical description using provides good representation over wide range conditions. These results should allow estimation distributions other...
