Cannabis sativa L. is emerging as an economically important crop, particularly for its high levels of cannabinoid production. One of these cannabinoids, cannabigerolic acid (CBGA), is the precursor to many well-researched cannabinoids such as the psychotropic delta-9-trans-tetrahydrocannabinolic acid (Δ9-THCA i.e., THCA) and the medically relevant cannabidiolic acid (CBDA). CBGA has...
Coal continues to be burned by direct combustion in packed or moving bed in
small size domestic furnaces, medium size industrial furnaces, as well as small power
stations. Recent stringent restrictions on exhaust emissions call for a better
understanding of the process of combustion of coal in beds.
The present...
The purpose of this paper is to compare the estimated production of the pendulum swing logging system to the production of a conventional balloon logging system. Cycle Time is established for the conventional system by time study techniques. A combination approach is used to model the pendulum system. A computer...
The genus Deraeocoris Kirschbaum of western America north of
Mexico was revised. Approximately 10,000 specimens from the Nearctic
Region were examined. Taxonomic characters used by previous authors
were reevaluated. In addition to the male parameres, the male vesica
and the female posterior wall of the bursa copulatrix and sclerotized
rings...
The utero-ovarian vasculature of domestic animals has been a
popular research subject, especially concerning the roles of the uteroovarian
artery and vein in the unilateral luteolytic phenomenon
demonstrated in these animals. No reports in the literature, however,
have been found regarding the smooth muscle physiology of these vessels.
The present...
The purpose of this study was to investigate several hypotheses concerning specific demonstrable attitudes toward education, critical thinking ability, and affective behaviors as these were manifested by students in the BSCS environmental module, Investigating Your Environment (IYE), and in more structure-oriented biology classes. Participants in the study were students in...
The salt marshes of the Salmon River Estuary, Oregon have been of interest for decades due to their disturbance and restoration history, as well as the presence of long-term vegetation transects that were established as early as the 1970s. Vegetation abundance data have been gathered in the four sites of...
