Observations of the motor patterns used by patas monkeys during allogrooming indicate that this species uses oral movements much more than previously believed. Compared to rhesus macaques, patas show more mouthpicks and licks, and fewer handpicks. Despite behavioral and anatomical evidence for good precision gripping, patas usually remove debris from a partner's fur orally rather than manually. 相似文献

This paper demostrates the presence of neuraminidase (EC 3.2.1.18) in the isolated gastic mucoproteins, and indicates its probable origin from bacteria in the mucous secretion. The sialic acid content of gastric mucoproteins is discussed in terms of these findings. 相似文献

Hispanic construction workers, particularly those born outside of the United States, are a growing segment of the Texas workforce and are increasingly the victims of on-the-job fatalities. This study examines occupational fatality characteristics among Hispanic construction workers utilizing records collected by the Texas Workers' Compensation Commission for the Bureau of Labor Statistics, Census of Occupational Fatal Injuries program. Of the 370 fatalities recorded from 1997 to 1999, 179 cases (46.5%) involved Hispanic workers — 109 of who were born in a foreign country. The fatality rate for Hispanic construction workers was 23.5 per 100,000 workers compared to 21.2 for non-Hispanic workers. Many fatally injured Hispanic construction workers shared similar characteristics including: low skill level, young age and foreign birthplace. Hispanic workers employed as construction laborers, helpers, and roofers had the highest number of fatalities. Businesses with fewer than 10 workers employed forty-two % of all Hispanic decedents, and businesses with more than 100 employees comprised twenty % of fatalities. The leading causes of Hispanic fatalities were: transportation incidents, falls, and exposure to harmful substances. 相似文献
