Two rectangular 10-ha plots (200 x 500 m) were established in each of the two main forest types of the Ituri Forest, Democratic Republic of Congo (formerly Zaire). The description of stand structure and species diversity, the comparison of the two forest types, and the evaluation of the effects of...

In recent years, monarch butterfly (Danaus plexippus) populations have declined at an alarming rate resulting in an extensive conservation effort across the species’ migratory range. One hypothesis for declining populations is decreased reproductive success during spring migration. The eastern monarch population’s first annual generation occurs in the early spring when...
The objective of this study was to identify the varying effects of altering the rumen fluid: substrate ratio on the outcomes of in vitro rumen fermentation. In vitro fermentation is a useful tool for evaluating the energy value of feedstuffs and the effect of feed additives on Volatile Fatty Acid...
Robotic limbs have been shown to enable mobility in unstructured, real-world terrain; they allow robots to step around cluttered environments, scramble up hills, carry heavy loads, and even perform acrobatics. However, mechanical limbs cannot operate as a means for such dynamic locomotion if they are simply treated as general articulated...
Economic, environmental, social and political influences made the management of
solid waste or garbage an important issue for all foodservice directors, including those
in health care facilities. The study objectives were to: (1) identify what components
of integrated waste management programs were being used in hospital foodservice
facilities in Oregon,...
The objective of this study was to identify usage of foodservice performance
measures, important activities in foodservice benchmarking, and benchmarking
attitudes, beliefs, and practices by foodservice directors. The design of this study
included two parts: (1) eleven expert panelists involved in a Delphi technique to
identify and rate importance of...
The sorbed gases at all four Ocean Drilling Program Leg 139 sites (855, 856, 857, and 858) showed the unmistakable presence of thermogenic hydrocarbons. No indication of abiogenic gas was found. The evidence for the thermogenic hydrocarbons includes elevated contents of higher hydrocarbons (i.e., C₁/[C₂ + C₃] ca. 2-20), δ¹³CCH₄...
