T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
School districts across the nation are engaged in an ongoing attempt to bring about
change. Educational researchers strive to initiate change in the classroom with students as
well as the teachers of these students.
The evaluation of a change effort is a key element in any implementation model; as
the...
Stratigraphy and chronology are essential to sedimentological study of Earth system histories. And, stratigraphy and chronology are often challenging and interesting problems themselves. The Quaternary (2.588 Ma - present) experienced paleoenvironmental and paleo-geomagnetic variability well outside the range of the recent instrumental record, providing the opportunity to place recent observations...
The differential cross section for the reaction k⁻+p[forward arrow] k⁰+[uppercase xi]⁰ was measured in a spark chamber experiment for an incident k⁻ momentum of 1.8 GeV/c. The target was liquid hydrogen confronted
by an anti-coincidence counter to insure neutral particle production.
A 60 element hodoscope signalled the presence of four...
This dissertation concentrates on the controlling factors on the instability of the Laurentide Ice Sheet (LIS) and their effects on abrupt climate change. Northern Hemisphere climate fluctuated abruptly during the last deglaciation possibly related to variability in Atlantic meridional overturning circulation (AMOC) and reduced aerial extent of the LIS. Reductions...
The distribution of adult Pacific herring (Clupea harengue
pallasi) near Auke Bay, Lynn Canal, southeastern Alaska, varied by
depth and geographic area over 24 successive months during 1973-75.
From June through September, schools concentrated at 5- to 37-m
depths where zooplankton was abundant, and moderate currents were
present in a...
The genus Lichnanthe Burmeister contains eight extant and one
fossil species which are strictly nearctic in distribution. The
subfamily Glaphyrinae, however, is distributed nearly world-wide.
Five species were previously described and three are described as
new herein. All eight extant species are described in detail herein,
synonomies are made current,...
Boyd and Walter (1975) identified the need to provide supervision for school counselors almost forty years ago. Michelle Obama, the First Lady of the United States (2014), in her address at the American School Counselor Association Conference stated that school counselors needed to be provided with professional development opportunities designed...
