In the 19th century it was difficult for the growing number of medical practitioners in North America to access current medical literature. Various ways were suggested to solve this problem; one of them was the creation of physician-run medical library…

Gas phase displacement reactions of boron trihalides from their trimethylamine aducts show that the order of acceptor power is BBr3>BCl3>BF3>1/2(B2H6). This order agrees with recent theoretical calculations and dipole moment, calorimetric, and infrared measurements on boron trihalide complexes with other…

Measurements have been made on the angular dependence of the magnetoresistance effect and the Hall effect on oriented w-type indium antimonide samples. The measurements were taken at room temperature and liquid air temperature using a magnetic field strength of about…

The observation of delayed proton emission is reported. Bombardment of both aluminum and silicon with 97-Mev protons leads to the emission of delayed proton energy groups from to 5 Mev. They follow the beta decay of S25 (T1/2 about 0.3…

The delayed-proton precursor 33AR has been produced by proton bombardment of a lithium chloride target in the internal beam of the McGill synchrocyclotron. The Half-life of 33Ar was measure to be (178±10) msec. to explain the delayed proton spectrum, two…

Proton n.m.r. spectra of trimethylamine adducts of the boron trihalides and borane have been measured in chloroform solution. Chemical shifts of methyl protons relative to tetramethylsilane decrease in the order: BBr3 > BCl3 > BH3 > BF3, suggesting that this…

Last year, Stewart Brower, co-editor of the open access journal Communications in Information Literacy, defended the peer review process. He argued that despite its flaws, peer review helps librarians’ careers. “Peer-reviewed articles get librarians promoted. Peer-reviewed articles get librarians tenured.”…
