Tending Cattle After the Winter Storm

It appears the worst of the early February winter blizzard that swept across the state has past. As water sources thaw and leak repairs get underway, cattlemen might give some thought to forage condition

Grassfed Beef Business – Grand Future?

Once upon a time not all that long ago, all beef in North America was 100% grassfed. Cattle roamed freely over vast expanses of the Great Plains, much like the buffalo had grazed for hundreds of years. Spring roundups gathered and co-mingled herds of market-ready cattle that were grazed north to terminal markets and packing houses. This business model thrived through the post-Civil War years. By the late 1800’s, advancement of the railroad network brought an end to this romantic period of the US cattle industry

The Exponential of a Quaternionic Matrix

The exponential map is important because it provides a map from the Lie algebra of a Lie group into the group itself. We focus on matrix groups over the quaternions and the exponential map from their Lie algebras into the groups. Since quaternionic multiplication is not commutative, the process of calculating the exponential of a matrix over the quaternions is more involved than the process of calculating the exponential of a matrix over the real or complex numbers. We develop processes by which this calculation may be reduced to a simpler problem, and provide some examples

Governing patient safety in field hospitals: lessons for the future

Across the world, the COVID-19 pandemic has brought an unprecedented risk to the delivery and availability of healthcare. As hospital admissions soared with patients hospitalised with the effects of the virus, there was a growing demand to increase bed capacity. To increase this supply, field hospitals were commissioned. In the UK, nine field hospitals were commissioned, with their objectives to reduce deaths and free capacity in acute providers and allow referring hospitals to maintain flow in and out of their surge capacity.1 When the National Health Service (NHS) Nightingale Hospital London opened, it had a capacity of 500 beds, increasing to 4000–5000 if needed. Likewise, the NHS Nightingale Hospital Birmingham had a capacity of 596 and increasing to 4500. These field hospitals were set up rapidly, in a matter of months, with a focus on performance and operationalisation. However, a key question to consider and reflect on is how patient safety has been governed in this new delivery of care. Reflecting on this can ensure that safety and quality remains at the forefront of any future field hospitals
