Transplanting is a core part of factory nurseries and key factor in determining the healthy growth seedlings. While transplanting has single operational function, complete process sorting, replanting complex. This paper innovatively proposes an intelligent multi-functional seedling system, where functions can be achieved with machine. strategies dynamic detection during performing within same t...

Clostridium difficile enterotoxin (D-1) was detected in 13 symptomatic and nine asymptomatic neonates in the neonatal intensive care unit by latex agglutination test but was not found in 18 healthy neonates in two other newborn nurseries. Environmental contamination in the intensive care unit may have been the cause. An association between the presence of enterotoxin and clinical symptoms is di...

BACKGROUND Several studies have demonstrated an association between the exposure to indoor air pollution (IAP) and childhood asthma. Evidence is suggesting that several air pollutants may contribute to both exacerbation and development of asthma, but some uncertainty remains concerning the specific causative role of IAP. This paper reports an epidemiologic study aiming to reduce the existing la...

Stable carbon and oxygen isotopes in the otoliths of Atlantic bluefin tuna Thunnus thynnus were used to investigate trans-Atlantic movement and natal homing behaviors. Otolith δ13C and δ18O of yearling bluefin tuna from 6 different year classes (1999 to 2004) were characterized to validate the approach and assess inter-annual variation in these markers for individuals from eastern (Mediterranea...

The importance of a broad suite of complex structured habitats as nurseries for estuarine fauna is well recognized. In contrast, recent evidence indicates the nursery value of salt marshes and contiguous unvegetated mud flats for blue crabs are underestimated. To assess the nursery value of salt marsh tidal creeks for the blue crab Callinectes sapidus in coastal North Carolina, USA, we quantifi...

A study of nursery stock performance was conducted on four sites in the Tongass National Forest in southeastern Alaska: two sites at Fire Cove (Ketchikan Ranger District [R.D.]) and one each at Anita Bay (Wrangell R.D.) and Eight Fathom (Hoonah R.D.). Containerized Sitka spruce seedlings used in the study were grown at USDA Forest Service nurseries in Petersburg, Alaska, and Coeur d'Alene, Idah...
