Data are examined for the period 1968 to 1976 to provide a current look at public school teacher survival rates, and to update Charters’ findings reported in 1970. Results indicate that the downward sloping survival curve that Charters found still exists, although the curve has shifted up steadily through time. For example, of the cohort of new entrants to teaching in the St. Louis area in 1968, only 64.7% lasted beyond 1 year. Further, the survival rate differential between men and women has decreased over time to a point that the rates are virtually identical.

Cancer is the second leading cause of death globally; it accounted for 9.6 million deaths worldwide in 2018 (around 15% of all deaths). Of all deaths, 1 in 4 cases is attributable to different forms of oncological diseases [1]. Meanwhile the number of survivors continues to grow, not just because of earlier detection and treatment, but also because of revolutionary new therapies. About 9 million Americans of all ages are living with a current or past diagnosis of cancer; in 2007-13 five-year survival rates for all cancers increased to 67%. For many individuals, this changes the landscape from a terminal illness to more of a chronic illness with periods of remission and exacerbation of symptoms. This perspective on neoplasms has broadened the scope of care from treating the disease alone to managing cancerrelated symptoms at different stages of the disease trajectory including mental disorders. According to Holland, Alici, and Massie the prevalence of psychiatric disorders in cancer patients is over 50% [2, 3].

The prevalence and survival rates of critically ill patients with cancer in the intensive care unit have increased considerably in the past 2 decades; yet, the meaning of caring for cancer patients in this setting may fall along a continuum. This article addresses the nurse’s experience in caring for the critically ill patient with cancer by presenting a current profile of these patient in the intensive care unit in the context of the historical development and mission of critical care and the evolution of cancer as a chronic disease. The moral distress that can result when these 2 “cultures” or “realities” collide and the meaning of the nurse’s work will be examined. Strategies and resources for critical care nurses to incorporate into their practice when caring for the critically ill patient with cancer, and themselves, will be addressed.

The optic axis of an electron microscope objective lens is usually assumed to be straight and co-linear with the mechanical center. No reason exists to assume such perfection and, indeed, simple reasoning suggests that it is a complicated curve. A current centered objective lens with a non-linear optic axis when used in conjunction with other lenses, leads to serious image errors if the nature of the specimen is such as to produce intense inelastic scattering.

Palladium single-crystal films have been prepared by Matthews in ultra-high vacuum by evaporation onto (001) NaCl substrates cleaved in-situ, and maintained at ∼ 350° C. Murr has also produced large-grained and single-crystal Pd films by high-rate evaporation onto (001) NaCl air-cleaved substrates at 350°C. In the present work, very large (∼ 3cm2), continuous single-crystal films of Pd have been prepared by flash evaporation onto air-cleaved (001) NaCl substrates at temperatures at or below 250°C. Evaporation rates estimated to be ≧ 2000 Å/sec, were obtained by effectively short-circuiting 1 mil tungsten evaporation boats in a self-regulating system which maintained an optimum load current of approximately 90 amperes; corresponding to a current density through the boat of ∼ 4 × 104 amperes/cm2.

For future high density magneto-optical recording materials, a Bi-substituted garnet film ((BiDy)3(FeGa)5O12) is an attractive candidate since it has strong magneto-optic effect at short wavelengths less than 600 nm. The signal in read back performance at 500 nm using a garnet film can be an order of magnitude higher than a current rare earth-transition metal amorphous film. However, the granularity and surface roughness of such crystalline garnet films are the key to control for minimizing media noise.We have demonstrated a new technique to fabricate a garnet film which has much smaller grain size and smoother surfaces than those annealed in a conventional oven. This method employs a high ramp-up rate annealing (Γ = 50 ~ 100 C/s) in nitrogen atmosphere. Fig.1 shows a typical microstruture of a Bi-susbtituted garnet film deposited by r.f. sputtering and then subsequently crystallized by a rapid thermal annealing technique at Γ = 50 C/s at 650 °C for 2 min. The structure is a single phase of garnet, and a grain size is about 300A.

The biological effects of short-wave ultraviolet light has generally been described in terms of changes in cell growth or survival rates and production of chromosomal aberrations. Ultrastructural changes following exposure of cells to ultraviolet light, particularly at 265 nm, have not been reported.We have developed a means of irradiating populations of cells grown in vitro to a monochromatic ultraviolet laser beam at a wavelength of 265 nm based on the method of Johnson. The cell types studies were: i) WI-38, a human diploid fibroblast; ii) CMP, a human adenocarcinoma cell line; and iii) Don C-II, a Chinese hamster fibroblast cell strain. The cells were exposed either in situ or in suspension to the ultraviolet laser (UVL) beam. Irradiated cell populations were studied either "immediately" or following growth for 1-8 days after irradiation.Differential sensitivity, as measured by survival rates were observed in the three cell types studied. Pattern of ultrastructural changes were also different in the three cell types.

A current theme in the study of the critical current density behavior of YBa2Cu3O7-δ (YBCO) grain boundaries is that their electromagnetic properties are heterogeneous on various length scales ranging from 10s of microns to ˜ 1 Å. Recently, combined electromagnetic and TEM studies on four flux-grown bicrystals have demonstrated a direct correlation between the length scale of the boundaries’ saw-tooth facet configurations and the apparent length scale of the electrical heterogeneity. In that work, enhanced critical current densities are observed at applied fields where the facet period is commensurate with the spacing of the Abrikosov flux vortices which must be pinned if higher critical current density values are recorded. To understand the microstructural origin of the flux pinning, the grain boundary topography and grain boundary dislocation (GBD) network structure of [001] tilt YBCO bicrystals were studied by TEM and HRTEM.
