A Space-Based Solar Screen Against Climatic Warming, Michael Noah Mautner

Chemistry Publications

The expected global warming may be reversed by space-based screen that would intercept a fraction of the solar radiation incident on Earth. Warming by 2-5^oC could be prevented by intercepting 3-7%, respectively, of the incident solar radiation. The screen may be constructed for example of a thin film, a grid of film supported by a mesh or fine-grained dust deployed in orbit about the Earth. For an average film thickness or particle radius of 0.001 cm, the required mass is 10¹⁴ - 10¹⁵ g, equivalent to a medium sized lunar mountain or asteroid. The material may …

Efficacy And Cost-Effectiveness Of Adjuvant Chemotherapy In Women With Node-Negative Breast-Cancer - A Decision-Analysis Model, Bruce E. Hillner , M.D., Thimas J. Smith M. D.

Internal Medicine Publications

BACKGROUND.

In 1988 the National Cancer Institute issued a Clinical Alert that has been widely interpreted as recommending that all women with node-negative breast cancer receive adjuvant chemotherapy. Acceptance of this recommendation is controversial, since many women who would not have a recurrence would be treated.

METHODS.

Using a decision-analysis model, we studied the cost effectiveness of chemotherapy in cohorts of 45-year-old and 60-year-old women with node-negative breast cancer by calculating life expectancy as adjusted for quality of life. The analysis evaluated different scenarios of the benefit of therapy: improved disease-free survival for five years, with a lesser effect on …

Pharmacokinetics Of Ceftibuten-Cis And Its Trans Metabolite In Healthy Volunteers And In Patients With Chronic Renal Insufficiency, Judy Shepard Kelloway, Walid M. Awni, Chin C. Lin, Josephine Lim, Melton B. Affrime, William F. Keane, Gary R. Matzke, Charles E. Halstenson

Pharmacotherapy and Outcomes Science Publications

The impact of renal insufficiency on the dispositions of 300 mg of orally administered ceftibuten-cis, a new broad-spectrum oral cephalosporin, and its primary metabolite ceftibuten-trans was characterized in 30 adult subjects. Subjects were divided into five groups of six subjects each on the basis of their 24-h ambulatory creatinine clearances (CL_CR). The apparent total body clearance (CL_P/F; where F is absolute bioavailability) and renal clearance of ceftibuten-cis were significantly lower in subjects with end-stage renal disease (on maintenance hemodialysis; group V) and in those with severe (CL_CR, 5 …

Cyanonews (Vol. 7, No. 2, September 1991), Jeff Elhai

CyanoNews

CyanoNews was a newsletter that served the cyanobacteriological community from 1985 to 2003, with content provided by readers (sort of a blog before there were blogs). The newsletter reported new findings from the lab, summaries of recent meetings (often provided by graduate students and post-docs entering the field), positions sought or available, life transitions, a compendium of recent cyanobacteria-related articles, and other items of interest to those who study cyanobacteria.

Observation Of Eliminative Cationic Polymerization Within Van Der Waals Clusters, M. Samy El-Shall, K. E. Schriver

Chemistry Publications

We report the first observation of eliminative cationic polymerization within van der Waals (vdW) clusters following electron impact ionization at pressures of 10⁻⁸ Torr. The elimination reactions of C₂H₃Cl⁺ within the clusters terminate after three successive steps, each involving elimination of HCl or Cl. The results provide a mechanism for the early stages of gas phase cationic polymerization of vinyl chloride and demonstrate the feasibility of using vdW clusters as a means of studying gas phase cationic polymerization.

A Double Chain Of Coupled Circuits In Analogy With Mechanical Lattices, J. N. Boyd, P. N. Raychowdhury

Mathematics and Applied Mathematics Publications

A unitary transformation obtained from group theoretical considerations is applied to the problem of finding the resonant frequencies of a system of coupled LC-circuits. This transformation was previously derived to separate the equations of motion for one dimensional mechanical lattices. Computations are performed in matrix notation. The electrical system is an analog of a pair of coupled linear lattices. After the resonant frequencies have been found, comparisons between the electrical and mechanical systems are noted.
