—The Nebraska Sandhills are an important area for breeding ducks in the Great Plains, but reliable estimates of breeding populations are unavailable. Double-observer methodology was used to estimate abundance of breeding duck populations in the Nebraska Sandhills. Aerial transect surveys were conducted using methodology similar to the cooperative Waterfowl Breeding Population and Habitat Survey...

This study was conducted to investigate the prevalence and antimicrobial resistance of Salmonella spp. and Escherichia (E.) coli isolated from ducks in Korea. A total of 400 cecal content samples were collected from 40 duck farms in Korea. Isolated Salmonella spp. and E. coli strains were 83 and 364 of the 400 cecal samples, respectively. The most prevalent serotype among the 83 Salmonella isol...

With a quarter of the world’s population now having access to the internet, the area of web efficiency and optimal use is of growing importance to all users. The function of revisitation, where a user wants to return to a website that they have visited in the recent past becomes more important. Current static and textual approaches developed within the latest versions of mainstream web browsers...

In this paper we present S-pot, a benchmark setting for evaluating the performance of automatic spotting of signs in continuous sign language videos. The benchmark includes 5539 video files of Finnish Sign Language, ground truth sign spotting results, a tool for assessing the spottings against the ground truth, and a repository for storing information on the results. In addition we will make ou...

A study was conducted in two southern coastal districts of Bangladesh (Noakhali and Lakshmipur) to assess the potentiality of the existing duck rearing system of the regions in summer and rainy season. One upazila from each district and three villages from each upazila were selected randomly. Fifty farmers were selected from each village having at least 5 ducks throughout the year. Thus, a tota...

Mottled ducks Anas fulvigula are nonmigratory and primarily depend on habitats associated with coastal marshes of the Gulf Coast for their entire life cycle. Much of remaining available coastal marsh habitats of the Texas Gulf Coast are managed by state and federal agencies. The Texas Gulf Coast breeding population of mottled ducks has recently declined dramatically. To aid in development of ma...

What role does the wild duck play in Ibsen’s famous drama? I argue that, besides mirroring the fate of the human cast members, the duck is acting as animal subject in a quasi-experiment, conducted in a private setting. Analysed from this perspective, the play allows us to discern the epistemological and ethical dimensions of the new scientific animal practice (systematic observation of animal b...

The goal of academic undergraduate programs is to disseminate disciplinary ‘know-how’ and teach students to engage in professional practice once they have completed their studies. However, technological and scientific progress contribute continuously to a significant increase of knowledge. In consequence, theoretical information keeps augmenting, while time for assimilation and application exer...

The purpose of this paper is to seek the Committee’s advice on whether the risk to consumers (including vulnerable groups) from consuming lightly cooked or raw shell eggs and their products has changed since the Committee last reviewed the subject of Salmonella in eggs in detail between 1998 and 2001. The paper provides background on this issue in light of developments. While hen’s eggs are the...
