The answer -- 17,152 -- required a careful and systematic counting of all possibilities.
In addition, more than half of the reported near-misses for 2011 in Queensland (54 %, N = 253) were between a train and a pedestrian, noting that such data are likely to be underreported (i.e. these reports are provided by rail staff and therefore do not represent systematic counts) [3].
Careful systematic counting of large areas under the microscope detected very few K14+ cells (data not shown).
Systematic counts along transects of the resting platforms, or 'nests', that orangutans build have therefore been used as predictors, or as direct proxies, for population density.
The results from the diverse measures used (morphological appearance on sections, immunocytochemistry and western blotting of neuronal markers) indicate that loss of grey matter occurs only in the first 24 hours after injury, whereas white matter loss, the assessment of which included systematic counting of axonal profiles in semi thin sections, continues up to about 7 days post injury.
There are no systematic counts for organellar introns, but in May 2007 the intron database of ref. 2 contained 117 and 83 introns in rRNA and protein genes, respectively, of mitochondria.
The RNA-seq approach, which is based on ultra-high throughput sequencing of total RNA and systematic counts of all expressed transcripts, has the potential to overcome many of the limitations associated with microarray technology.
This contained a simulation of traffic flows on every segment of all freeways, arterials, and collectors attained from systematic counts conducted in the peak morning hours, from 0730 to 0830 hours.
Assessment of positive signal localizations throughout each cartilage zone included systematic counting of positive and negative cells in a 50 × 50 μm grid (40× field), starting from the cartilage surface, down through the full thickness tissue specimen.
For systematic counting, three ocular measuring fields, each with a real area of 0.06175 mm, were randomly chosen under a microscope at a power of × 400 within a section.
