Vigorous Summer Growth Peak growth of these grasses occurs during summer. They break dormancy in late March and early April and then grow rapidly from mid-May through midsummer. In late summer, growth slows until fall dormancy, usually in October. The maturity dates of the various species vary somewhat, but all follow this pattern. They remain dormant through winter. Five Key Species While ther...

This paper argues that new immigrants cluster in culturally homogenous groups in the host country because of imperfect information. However, the pulling-effect exists provided that the cultural communities are not too large. With a panel of migration flows to the major OECD countries from the mid-1980s to the mid-1990s, it is shown that the existence of similar cultural communities does attract...

First, the stage in the demographic transition. Since around the mid-1960s, lower EME fertility rates have meant lower dependency ratios, which has tended to boost saving, and also a rise in the working-age population, which has tended to boost investment. The transition has worked out as predicted in some countries but not in others. In particular, in the aftermath of crises (eg Asia in the la...

Paths assumed by tropical cyclones in different fall seasons are related to the form of the prevailing mid-tropospheric general circulation. It is inferred that areas of vulnerability or invulnerability to these storms seem to be prescribed by the climatologically preferred circulation pattern during a given year, and for this reason expanded research along these lines could be highly rewarding...

[1] We have measured winds using cloud motion in consecutive Mars Global Surveyor (MGS) Mars Orbiter Camera (MOC) wide-angle global map swaths taken during the first mapping year (Ls 135 –360 –111 ). We present a total of 11,200 wind vectors collected in the north polar region during Ls 135 –195 (late summer/early fall) and Ls 20 –55 (mid spring) and in the south polar region during Ls 337 –10 ...

Oral anticoagulant therapy (OAT) has a well-established efficacy in prophylaxis and treatment of thromboembolic disorders. Because complications are related to intensity of OAT, optimal control of treatment is mandatory. In studies of OAT, as many as 30% of International Normalized Ratio (INR) measurements for prothrombin times fall outside the therapeutic interval. Preanalytical, analytical, a...

We present results of ultra-deep ISOCAM observations through a cluster-lens at 7μm and 15μm with the Infrared Space Observatory (ISO) satellite. These observations reveal a large number of luminous Mid-Infrared (MIR) sources. Crossidentification in the optical and Near-Infrared (NIR) wavebands shows that about half of the 7 μm sources are cluster galaxies. The other 7 μm and almost all 15 μm so...
