PARasites in Organic Livestock: innovative solutions to new challenges [PDF]

Parasites are ubiquitous in livestock in general and organic livestock in particular due to manage-ment factors promoting transmission (pastures/outdoor runs, plenty of bedding, restrictive use of parasiticides).

Development of Stresses in Cohesionless Poured Sand

, 1998
The pressure distribution beneath a conical sandpile, created by pouring sand from a point source onto a rough rigid support, shows a pronounced minimum below the apex (`the dip').

Analytical stress solution framework for lined compressed air energy storage chambers and its application to safe burial depth determination and supporting effectiveness evaluation

Deep Underground Science and Engineering, EarlyView.
An analytical framework delivers a closed‐form stress solution for lined compressed air energy storage chambers, enabling the determination of the minimum safe burial depth. The solution quantitatively evaluates lining support effectiveness, offering a reliable tool for chamber design and optimization.

Influence of cutterhead opening ratio on soil arching effect and face stability during tunnelling through non-uniform soils

Underground Space
Tunnelling has increasingly become an essential tool in the exploration of underground space. A typical construction problem is the face instability during tunnelling, posing a great threat to associated infrastructures.

Ornamental grasses (2006) [PDF]

, 2006
Ornamental grasses make ideal garden plants. Most are quite vigorous, require minimal care and add color, form and texture to the landscape. They are available in sizes ranging from as short as 6 inches to as tall as 15 feet and can tolerate a wide array

A comprehensive embryonic staging series of the turtle Trachemys scripta

Developmental Dynamics, EarlyView.
Abstract Background Turtles hold a unique place in vertebrate evolutionary history, making them critical assets in embryology research. Yet, they remain understudied as potential model organisms in the field. Here, to support experimental manipulations with turtle embryos, we have created a complete normal table of development for comprehensive ...

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

Ecography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Policy Spandrels: How Design Decisions Can Open Up Spaces for Unintended Policy Change

European Policy Analysis, EarlyView.
ABSTRACT This article introduces the concept of policy spandrels to make sense of public policies producing second‐order effects that are unintentional from the perspective of policy design and yet are fraught with consequences. By analogy with architectural spandrels—leftover spaces that can be used for unforeseen purposes—policy change can be enabled
