An analysis of the forces required to drag sheep over various surfaces

Applied Ergonomics, 2002
Some occupational health and safety hazards associated with sheep shearing are related to shearing shed design. One aspect is the floor of the catching pen, from which sheep are caught and dragged to the shearing workstation. Floors can be constructed from various materials, and may be level or gently sloping.

The Power of Unity: Collective Action and Smallholder Agricultural Performance in West Africa

Agribusiness, EarlyView.
ABSTRACT We analyze the impact of collective action through farmer‐based organizations (FBOs) on smallholders' farm performance and income inequality in Ghana, Benin, The Gambia, and Mali. We find that FBO membership increases cereal yield in Ghana and The Gambia, legume yield in Mali, ruminant numbers in Benin and The Gambia, and total farm income in ...

Programmable Flocks: Hierarchical Swarm Control via Dynamic Parameter Injection

Advanced Intelligent Systems, EarlyView.
We present a method for the control of robot swarms which allows the shaping and the translation of patterns of simple robots (“smart particles”), using two types of devices. These two types represent a hierarchy: a larger group of simple, oblivious robots (which we call the workers) that is governed by simple local attraction forces and a smaller ...

Scrapie prevalence in sheep of susceptible genotype is declining in a population subject to breeding for resistance [PDF]

, 2010
Background Susceptibility of sheep to scrapie infection is known to be modulated by the PrP genotype of the animal. In the Netherlands an ambitious scrapie control programme was started in 1998, based on genetic selection of animals for breeding.

Causal analysis of trade loss from pathogens: A global study of foot and mouth disease impacts on meat exports

American Journal of Agricultural Economics, EarlyView.
Abstract Our general interest is in global trade loss from livestock pathogens, specifically exports. We adopt a causal inference approach that considers animal disease outbreaks over time as non‐staggered binary treatments with the potential for switching in (infection) and out of treatment (recovery) within the sample period. The outcome evolution of

Safety and Feasibility of Magnetic Separation‐Based Blood Purification

Advanced NanoBiomed Research, EarlyView.
We present the preclinical biological safety and translational feasibility of a magnetic nanoparticle‐based extracorporeal blood purification platform for removal of disease‐causing blood factors. ISO 10993‐compliant studies and exaggerated worst‐case exposure models demonstrate efficient nanoparticle extraction (≥99.9%), favorable biocompatibility ...

Hormone glycosylation required for lutropin receptor recognition in sheep testis

FEBS Letters, 1990
The high affinity binding sites for ovine pituitary lutropin (oLH) present in DLS‐1 sheep testis recognized only the fully glycosylated ovine or bovine hormone (bLH) in receptor binding assays using 125I‐labeled oLH. Chemically deglycosylated (DG‐) oLH or bLH which were fully active with other lutropin receptors (rat/pig) were completely inert in the ...

Silk Fibroin for Cardiovascular Medical Devices: Review of Material Properties, Applications, and Clinical Potential

Advanced NanoBiomed Research, EarlyView.
Silk fibroin is an attractive natural biomaterial that can be engineered into diverse cardiovascular constructs, including vascular grafts, cardiac patches, heart valves, and stent coatings. Its tunable biological and mechanical properties have driven substantial preclinical progress; however, widespread clinical translation in cardiovascular ...

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

The Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...
