Severity classification of repeated isoflurane anesthesia in C57BL/6JRj mice-Assessing the degree of distress. [PDF]
PLoS ONE, 2017 According to the EU Directive 2010/63, the severity of a procedure has to be classified as mild, moderate or severe. General anesthesia is thought to be mild, but the Directive does not differentiate between single and repeated anesthesia.

Effects of population density on the sediment mixing induced by the gallery-diffusor Hediste (Nereis) diversicolor O.F. Müller, 1776 [PDF]
, 2006 The aim of this work was to quantify the intensity of sediment mixing induced by the gallery-diffusor (functional bioturbation group) Hediste diversicolor as a function of density, using particles tracers (luminophores).

Animals, 2020 Pain management during in vivo experiments is an animal welfare concern and is in many countries also legally required. In this study, we evaluated C57Bl/6J mice when 3 g/L metamizole or 1 g/L tramadol was provided via drinking water, before and during ...

Effects of separated pair housing of female C57BL/6JRj mice on well-being
Scientific Reports, 2022 In laboratory animal facilities, it is a common code of practice to house female mice in groups. However, some experimental conditions require to house them individually, even though social isolation may impair their well-being.

2D linear friction weld modelling of a Ti-6Al-4V T-joint [PDF]
, 2015 Most examples of linear friction weld process models have focused on joining two identically shaped workpieces. This article reports on the development of a 2D model, using the DEFORM finite element package, to investigate the joining of a rectangular Ti-

Comment on "Bilaterian Burrows and Grazing Behavior at >585 Million Years Ago" [PDF]
Science, 2013 Pecoits et al . (Reports, 29 June 2012, p. 1693) describe bilaterian trace fossils and assign them an Ediacaran age based on the age of a granite interpreted as intrusive. We argue that the granite is not intrusive but in fact represents the basement of the sedimentary succession.

, 2016 — The Pacific sand lance ( Ammodytes personatus ) is a small, elongate forage fish that spends much of its life buried in the sea-floor. We determined that the Pacific sand lance can burrow in a wide variety of sediments from silt to gravel, but it ...

Burrowing and subsurface locomotion in anguilliform fish: behavioral specializations and mechanical constraints [PDF]
Journal of Experimental Biology, 2011 SUMMARYFish swimming is probably one of the most studied and best understood locomotor behaviors in vertebrates. However, many fish also actively exploit sediments. Because of their elongate body shape, anguilliform fishes are not only efficient swimmers but also very maneuverable.
