—Biological data are limited for American eels Anguilla rostrata from the northern portion of the species’ geographic range. The biological characteristics of American eels from two sites in western Newfoundland varied by sex, maturation stage, and habitat. Female and male sexually mature (silver) eels from the Castors River were comparable in length range with eels reported from other Newfound...

Sheemar A, et al. BMJ Case Rep 2017. doi:10.1136/bcr-2017-222596 Description A 13-year-old Indian girl presented with painless vision loss in left eye since 3 months which was gradual in onset. She had been treated with intravenous steroids for optic neuritis 2 months earlier when her visual acuity had improved from 20/200 to 20/20 in left eye. Currently, she complained of recurrent episodic vi...

The song of male Zebra Finches has been the focus of decades of behavioural, developmental, neurobiological and, increasingly, genomic research. Zann was the first to summarise the immense and integrative research effort in a landmark synthesis of field and laboratory studies of Zebra Finches, which paralleled his own championing work on the sociality and vocal behaviour of estrildid finches in...

—Otolith Sr:Ca ratios were used to determine migrational histories of American eels Anguilla rostrata in an eastern Canadian coastal stream that is impounded at the head of tide. American eels sampled from the estuary were smaller (41.0 6 9.3 cm [mean 6 SD], N 5 324) and younger (ages 1–4) than those in a freshwater pond (65.0 6 7.5 cm, N 5 265; ages 11–26) 2.5 km upstream of the head of tide. ...

This article reports on two workshops in 2005, one in India and the other in the United States, to promote international research in vision and ophthalmology. The workshops were held in February and April and spanned a total of 7 days. They were sponsored by the Association for Research in Vision and Ophthalmology (ARVO) and funded through a cooperative agreement with the National Eye Institute...

TB or not TB? That is the question. Tuberculosis remains an extremely common infection worldwide, with perhaps 30% of world’s population having been exposed to Mycobacteria tuberculosis. In a study 656 212 college freshmen in Zhengzhou, China, between 2004 and 2013, nearly 41% showed positive tuberculin skin test results.1Wang Y.-H. Tian Y.

Socioeconomic determinants are investigated for both the likelihood of consuming fastfood and household expenditure on fastfood using the 1994-98 USDA Continuing Survey of Food Intakes by Individuals. The logit model is used to estimate an empirical relationship between probability an individual will consume fastfood and socioeconomic variables. The Tobit model is used to estimate an empirical ...

Two aspects of patch geometry—area and isolation—currently dominate the field of metapopulation dynamics. Under this area-and-isolation paradigm, models commonly assume that the probability of local extinction decreases as patch area increases and that the probability of colonization increases as patch connectivity increases. Environmental variables other than patch area and isolation are assum...

The purpose of this article is to show the history Ukrainian archives development in 20th and 21st centuries context national statehood processes struggle for Ukraine’s independence; determine challenges that threatened during First Second world wars, related destruction, seizure, transferring document collections. author pays special attention analysis archivists’ role preserving historical cu...

We describe the use of a recommender system to enable continuous knowledge acquisition and individualized tutoring of application software across an organization. Installing such systems will result in the capture of evolving expertise and in organization-wide learning (OWL). We present the results of a year-long naturalistic inquiry into application’s usage patterns, based on logging users’ ac...
