Dipteropeltis – a hundred years later

Word deafness: one hundred years later.

Since its original description the diagnosis of word deafness has been greatly expanded. Confusion has arisen with regard to the usage of the related terms pure word deafness, auditory agnosia, and cortical deafness. Three new cases of word deafness are presented including one case with CT and necropsy correlation. These cases are compared with 34 previously reported cases of various cortical a...

He was the treasurer of the Lodge and his name was the Reverend Prebendary Charles Waton. He was the Vicar of St Benet Fink, Edmonton and was a Grand Officer. To me, he was a very important maso...

Indoor radon entry: 30 years later

The paper discusses the results of 30 years of radon indoor entry research. While some progress has been made, many discrepancies between current theories and experimental data still remain. Misconceptions of radon transport mechanisms in homes are analyzed. The role of US Environmental Protection Agency in radon indoor entry research is examined and the agency's policies are criticize...

The last hundred years.

A Hundred Years of Larmor Formula

Sir Joseph LARMOR showed in 1897 that an oscillating electric charge emits radiation energy proportional to (acceleration) 2. At first sight,the result appears to be valid for arbitrary accelerations. But, perpetual uniform acceleration has been a case of nagging doubts, as radiation reaction vanishes and the equivalence principle, as also conformal symmetry of Maxwell equations each require ni...
