J. Hoffmann on Tetany—Oppenheimer on Railway Spina

Pedunculated lipofibroma (Hoffmann-Zurhelle) on the palm.

A 47-year-old woman presented with a 1-year history of a nodule on her right palm. She stated that the lesion had originally appeared without any trigger one year previously and that it had gradually increased in size. Physical examination revealed a pedunculated, solitary, asymptomatic nodule, 30 × 30 mm (Fig. 1). The prominent stalk was 8 mm long. The nodule was smooth, skin-coloured and soft...

A hungarian study on Werdnig-Hoffmann disease.

The prevalence of Werdnig-Hoffmann disease was found to be 0.66 per 10,000 livebirths in Hungary from 1973 to 1980. However, the true prevalence is estimated to be 1 per 10,000 livebirths, which exceeds the level of a previously published English study. There was no higher fetal death rate in previous and subsequent pregnancies of index patients' mothers. The occurrence in sibs was 32%, probabl...

Study on new crashworthy buffers in railway

At the collision time, a lot of energy is generated during a short period of time that causes large deformations in bodies. One of the most important parts of wagon in railway is a buffer which may absorb the energy during an impact. It should be mentioned that normal buffers only absorb the energy resulted from a crash elastically. In the present paper, it is tried to use inversion mode of ...

Detecting Plants on Railway Embankments

This paper investigates problems concerning vegetation along railways and proposes automatic means of detecting ground vegetation. Digital images of railway embankments have been acquired and used for the purpose. The current work mainly proposes two algorithms to be able to achieve automation. Initially a vegetation detection algorithm has been investigated for the purpose of detecting vegetat...
