Treatment Modality And Quality Differences For Black And White Breast Cancer Patients Treated In Community Hospitals, Paula Diehr
Treatment Modality And Quality Differences For Black And White Breast Cancer Patients Treated In Community Hospitals, Paula Diehr
Paula Diehr
This study assessed the relationship of race and patterns of care, defined by an expert NCI-appointed committee, for 7,781 patients with breast cancer treated in 107 hospitals in 45 communities between 1982 and 1985. After control for age and stage of disease, black patients had significantly different care from white patients for four of the ten patterns examined. They were less likely to have a progesterone receptor assay or to be referred for postmastectomy rehabilitation, two patterns deemed desirable for all patients. Black patients were also more likely to receive liver scans and radiation therapy in situations in which these …

Dissipative Model Of The Universe, Milan Meszaros
Dissipative Model Of The Universe, Milan Meszaros
Milan Meszaros physicist
In the present study a trial is carried out to generalize the non-relativistic-dynamic model of cosmology put forward by O. Heckmann. The generalization is performed under the framework of the Gyarmati principle of irreversible thermodynamics for anisotropic inhomogeneous and viscous case. The equation of motion of the dissipative Universe will be a Navier-Stokes tensor equation leading to a Riccatian differential equation general in one dimension. The equations of the Heckmann model compatible with standard cosmology can be obtained from this by means of further simplifying assumption.
Direct Tests Of The Rational Expectations Hypothesis: A Study Of Italian Entrepreneurs’ Inflationary Expectations (1980-1988), Claudio Lupi
Direct Tests Of The Rational Expectations Hypothesis: A Study Of Italian Entrepreneurs’ Inflationary Expectations (1980-1988), Claudio Lupi
Claudio Lupi
The primary concern of this paper is to test the rational expectations hypothesis for Italian entrepreneurs' inflationary expectations between 1980 and 1988 using monthly observed expectations. Particular care is devoted to analyzing the problems arising when multiperiod expectations and a nonwhite noise measurement error in the expectations series are considered. The empirical analysis is carried out using cross correlations on ARIMA residuals and transfer function models. This technique seems to be particularly appealing for rationality testing.
A Simple Monochromatic Spark Discharge Light-Source, Chin Oi Hoong
A Simple Monochromatic Spark Discharge Light-Source, Chin Oi Hoong
Chin Oi Hoong
Spark light illumination has been used in high-speed photog-raphy since the beginning ofthe century and various designs ofthe spark discharge light source have since been reportedr with spark duration ranging from nanoseconds to millisec-onds. We report here a simple and easy to build spark dis-charge tube for operation as a monochromatic point light source. The design and construction ofthe spark discharge tube is shown in Fig. 1. The sharp-tip solid cone anode is made of stainless steel which is screwed onto a brass rod connected A compact spark discharge tube operated as a monochromatic light source at 587.5 nm is …
Surficial Geologic Map Of The East Cache Fault Zone, Cache County, Utah, James P. Mccalpin
Surficial Geologic Map Of The East Cache Fault Zone, Cache County, Utah, James P. Mccalpin
James P. McCalpin
The 1:50,000-scale map shows surficial geologic deposits and the faults that displace them along the East Cache fault zone in northern Utah. The East Cache fault is a north-trending normal fault that extends about 77 km along the eastern side of Cache Valley (an east-tilted graben) at the base of the Bear River Range. The map includes a description of Quaternary deposits along the fault zone, a description of the fault segments, and estimates of the age, size, and distribution of fault scarps in the fault zone.
