In this study, we analyzed all known protein sequences for repeating amino acid segments. Although duplicated sequence segments occur in 14 % of all proteins, eukaryotic proteins are three times more likely to have internal repeats than prokaryotic proteins. After clustering the repetitive sequence segments into families, we find repeats from eukaryotic proteins have little similarity with prok...

all surgical positions carry some degree of position-related risks. the most common serious positional injuries are peripheral nerve injuries. we present a case of 23 years old man with obturator nerve injury with clinically evident sequelae following a scapulopexy of the right shoulder in prone position. basis on our knowledge, no similar cases have been described in the literature. the purpos...

This paper aims at understanding why road accidents tend to cluster in specific road segments. More particularly, it aims at analyzing which are the characteristics of the accidents occurring in "black" zones compared to those scattered all over the road. A technique of frequent item sets (data mining) is applied for automatically identifying accident circumstances that frequently occur togethe...

car manufacturing industry accident’s rates from three major companies are analyzed. totally 1325 accidents with 4 cases of fatality were recorded. accident rates per 100 full-time workers have gradually increased from 5.3 to 8.7 during 3 years of study. most of the accidents occurred during the primary hours of the work, strains and sprains represented the most frequently occurring type of inj...
