MINDED LAND RECLAMATION IN THE NORTHERN GREAT PLAINS: HAVE WE BEEN SUCCESSFUL ?

I-36: Preimplantation Genetic Diagnosis - Where Have We Been and Where Are We Going

Preimplantation genetic diagnosis (PGD) is now considered routine in IVF laboratories with micromanipulation capability and access to genetic diagnostic services. The past two decades have witnessed a dramatic increase in the use of PGD, the number of cycles performed, and the indications for which PGD has been used. This increase has been mirrored by a slow, but steady, increase in the range o...

Spatial variability of climate and land-use effects on lakes of the northern Great Plains

Evaluation of the effects of climate change and human activities on lakes requires improved understanding of how stressors interact and the degree to which individual sentinel lakes represent broad spatial patterns of ecosystem response to disturbance. We surveyed modern water chemistry (major ions, conductivity, salinity, lake volume) and sediments (algal pigments, stable isotopes) in 21 lakes...

We Have Always Been . . . Cyborgs

philosophy of mathematics suited well the ‘‘general emphasisin later nineteenth-century mathematics on revisiting foundationalquestions’’ (p. 61). Pure geometry as it emerged from Frege, Paschand Hilbert, provided a diagram-free, purely sentential notion ofproof, which has lasted unto our own day.In the second, and greater, part of the book, Greaves traces outthe interre...

Quality and persistence of forages in the Northern Great Plains

Integrating use of seedings of perennial cool-season grasses with native range is used to increase available forage and for maintaining a high plane of nutrition for grazing livestock. Our goal was to evaluate performance of yearling cattle and stand persistence of 3 released wheatgrass cultivars. Twice replicated 3-ha pastures were seeded to ‘Rosana’ western wheatgrass [Pascopyron smithii (Ryd...
