The Non‐Professional Virtues of the Hospice Volunteer

open access: yesJournal of Applied Philosophy, EarlyView.
ABSTRACT Volunteers have long played a significant role in hospice care. Much of the care volunteers provide consists of weekly hour‐long in‐home visits. Home‐visiting hospice volunteers are not professionals, nor are they strangers or intimates. Hospice volunteers will not typically face moral dilemmas, nor be called upon to make dramatic decisions ...

Coccolithophore particulate inorganic and organic carbon ratios: An evaluation of acid decalcification methods

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Accurate direct measurements of coccolithophore particulate inorganic and organic carbon ratios (PIC/POC) are crucial for understanding the physiology and role these microbes play in global ocean carbon flux. Direct measurements of POC are commonly obtained by acid fuming or applying acid directly to filters to dissolve PIC (CaCO3) prior to CN

Advances and Current Progress of Dopant Engineering on All‐Inorganic Halide Perovskites Toward High‐Performance Scintillating Materials

open access: yesMetalMat, EarlyView.
This review provides the latest advancement on lead‐free all‐inorganic perovskites, covering fundamental aspects, emerging synthetic routes, and scintillation properties. We highlight the dopant engineering strategy to favor the formation and efficient radiative recombination of self‐trapped excitons and the future development direction for the next ...

Use of a filter-paper disk assay in the measurement of lipid biosynthesis

open access: yesJournal of Lipid Research, 1966
The precipitation by trichloroacetic acid (TCA) of radioactive lipids on disks of filter-paper, followed by extraction with TCA and water to remove soluble radioactive precursors, provides the means for a convenient assay for lipid biosynthesis.

Fabrication of amorphous lamellar freestanding poly(N‐dodecyl acrylamide) films and their mechanical properties

open access: yesPolymer International, EarlyView.
A freestanding film of completely uniaxially oriented amorphous lamellae was produced. The film exhibited enhanced tensile strength with increasing orientation of the lamella. Abstract An amorphous lamellar freestanding film composed of poly(N‐dodecyl acrylamide) (pDDA) was prepared by annealing a micrometer‐thick film under humid conditions (humid ...

Scintillation Counting of Carbon-14

open access: yesNature, 1960
Eng.). Nature 186, 613-14(1960) May 21. A precise method is described for the radioassay of carbon-14 in aqueous solutions. The method was developed for use in work on the decomposition in soil of plant material labeled with carbon-14 and is suitable for handling large numbers of samples with specific activities of 0.1 to 10 mu c.
