Reduction of Data for Piston Gage Pressure Measurements

Reduction of Data for Piston Gage Pressure Measurements

Date: June 17, 1963
Creator: Cross, J. L.
Description: Report discussing pressure measurements made with piston gages that are affected by gravity, temperature, pressure, and several other variables. For accurate determinations of pressure the calculations must take these variables into account. A general equation is developed and simplified procedures for calculating pressure are illustrated.

A Study of Lunar Surface Radio Communication

A Study of Lunar Surface Radio Communication

Date: September 14, 1964
Creator: Vogler, L. E.
Description: Report discussing the problem of point-to-point radio communication on the moon. Equations and curves are presented to estimate power requirements in lunar communication systems. Consideration is given to ground wave attenuation over both layered and non-layered grounds, antenna ground losses in situations where ground screens are impractical, noise level estimates in the receiving system, and the effects on propagation of possible lunar ionospheres. An example of the calculation of required power for a particular communication system is given, and further studies are suggested.

A Complete Mode Sum for LF, VLF, ELF Terrestrial Radio Wave Fields

A Complete Mode Sum for LF, VLF, ELF Terrestrial Radio Wave Fields

Date: October 1, 1964
Creator: Johler, J. Ralph & Berry, Leslie A.
Description: Report discussing the VLF, ELF propagation in the earth-ionosphere waveguide emphasizing the total field found by summing all modes which contribute appreciably. Solutions are given and calculations are made for a homogeneous isotropic ionosphere, a homogeneous ionosphere with a constant radial magnetic field imposed, and an ionosphere with a magnetic field of arbitrary dip angle.

Mathematics Anxiety and Mathematics Self-efficacy in Relation to Medication Calculation Performance in Nurses

Mathematics Anxiety and Mathematics Self-efficacy in Relation to Medication Calculation Performance in Nurses

Date: May 2012
Creator: Melius, Joyce
Description: The purpose of this study is to identify and analyze the relationships that exist between mathematics anxiety and nurse self-efficacy for mathematics, and the medication calculation performance of acute care nurses. This research used a quantitative correlational research design and involved a sample of 84 acute care nurses, LVNs and RNs, from a suburban private hospital. the participants filled out a Mathematics Anxiety Scale, a Nurse Self-Efficacy for Mathematics Scale and also completed a 20-item medication calculation test. Significant practical and statistical relationships were discovered between the variables utilizing multiple linear regression statistics and commonality analysis. As the Nurse’s Mathematics anxiety score increased the scores on the medication test decreased and the scores on nurse self-efficacy for mathematics scale also decreased. the demographic item of “Hours a nurse worked in one week” had the greatest significance. the more hours a nurse worked the lower their score was on the medication calculation test. This study agrees with others that nurses are not good at mathematics. This study also correlated that as the number of hours worked increased so did the medication calculations errors. and many nurses have a measurable level of anxiety about mathematics and dosage calculations and this may influence ...

Annotated Bibliography on Soft X-ray Spectroscopy

Annotated Bibliography on Soft X-ray Spectroscopy

Date: June 29, 1962
Creator: Yakowitz, Harvey, 1939- & Cuthill, J. R.
Description: Report presenting a bibliography of about 550 references of the soft X-ray literature since 1950 and through 1960. The emphasis is on the application of soft X-ray spectroscopy to the study of valence band electronic states in metals and alloys. Therefore, the spectral region of 25 to 800 angstroms involving ruled glass grating spectrometers is of principal interest. In addition to soft X-ray data, references on all pertinent aspects of the apparatus and experimental problems are included. Also listed separately are references of value in corroborating soft X-ray data with other results. Subject, author, X-ray band, material, and other indices are included.
