Restriction of behavioral opportunities and uneven use of space are considerable welfare concerns in modern broiler production, particularly when birds are kept at high densities. We hypothesized that increased environmental complexity by provision of barrier perches would help address these issues by encouraging perching and enhancing use of the pen space across a range of stocking densities. ...

results long-term exposure to lead acetate caused histopathology effects including dilatation, congestion, nuclei heterochromatic effects, increase in diameter of renal tubules and urinary barrier thickness in rabbit renal tissue. conclusions quantitative and qualitative results of long-term lead acetate exposure showed many histopathology side-effects, especially in the urinary barrier. materi...

The uncertainties surrounding present and future sea-level rise have revived the debate around sea-level changes through the deglaciation and mid- to late Holocene, from which arises a need for high-quality reconstructions of regional sea level. Here, we explore the stratigraphy of a sandy barrier to identify the best sea-level indicators and provide a new sea-level reconstruction for the centr...

Multilayer films are widely used in packaging industry to fulfil different applications. It is well known that multilayer structure is essential for high gas barrier packaging using EVOH, because moisture has negative effects on EVOH’s barrier properties [1, 2]. In order to effectively use EVOH in barrier applications, usually a moisture barrier layer and a tie layer are required [3, 4]. In thi...

Abstract. Whereas efficient barrier implementations were once a concern only in high-performance computing, recent trends in core integration make the topic relevant even for general-purpose CMPs. While the nature of CMP applications requires low-latency, the cost of low-latency barrier implementations using hardwarebased techniques can be prohibitive for CMPs, where die area represents opportu...

West, John B. Invited Review: Pulmonary capillary stress failure. J Appl Physiol 89: 2483–2489, 2000.—The pulmonary blood-gas barrier is an extraordinary bioengineering structure because of its vast area but extreme thinness. Despite this, almost no attention has been given to its mechanical properties. The remarkable area and thinness come about because gas exchange occurs by passive diffusion...
