Circulating erythroblasts of embryonic mice were karyometrically examined by light microscopy. In the erythroid cells in embryonic blood vessels, mitoses were encountered from 9 to 12 days of gestation. At 9 days, the circulating blood cells consisted of proerythroblasts and less mature cells. The nuclear diameter ranged from 4.8 to 9.8 micron, the majority ranging between 6 and 8 micron. At 11...

One of the most important tasks of the perfusionist is the proper assembly of the extracorporeal circuit (ECC) prior to the initiation of cardiopulmonary bypass (CPB). The ECC is usually assembled, primed and debubbled 30 minutes to one hour prior to the patient entering the operating room. But there are occasions when the ECC may have been set up and the previously scheduled procedure cancelle...

Principal components analysis (PCA) is a basic and widely used technique for exploring data. If you go on to take specialized courses in machine learning or data mining, you’ll certainly hear more about it. The goal of this lecture is develop your internal mapping between the linear algebra used to describe the method and the simple geometry that explains what’s really going on. Ideally, after ...

Earlier phylogenetic studies based on the inferred DNA sequences of the polC, rpoB and gyrA genes suggested that strains of the species Bacillus subtilis formed two clusters, indicating the presence two closely related taxa; one contained the laboratory strain 168 and the other the laboratory strain W23. Significant sexual isolation was found between strain 168 and members of the group containi...

Q-switched output of 1.1 J per pulse at 2-micron wavelength has been achieved in a diode pumped Ho:Tm:LuLF laser using a side-pumped rod configuration in a Master-Oscillator-Power-Amplifier (MOPA) architecture. This is the first time that a 2-micron laser has broken the Joule per pulse barrier for Q-switched operation. The total system efficiency reaches 5% and 6.2% for single and double pulse ...
