The purpose of this study was to evaluate the effect of alprazolam on the stress that Korean raccoon dogs (Nyctereutes procyonoides koreensis) may experience while caught in a live trap by measuring their serum cortisol response. The animals were placed in a live trap with or without being pretreated with oral doses of alprazolam. In both groups, pre-trap blood samples were initially collected ...
55th ASMS Conference – Indianapolis 2007 www.chemistry.wustl.edu/~msf/ Overview Purposes •Evaluate the resolving power and sensitivity achievable with a new compensated trap for FTMS as a function of m/z and develop a protocol for tuning this trap. Methods •Sample empirically the cyclotron frequency surface at various cyclotron radii and z-mode amplitude distributions. •Compare the mass resolvi...
We realize a combined trap for bosonic chromium (Cr) and rubidium (Rb) atoms. First experiments focus on exploring a suitable loading scheme for the combined trap and on studies of new trap loss mechanisms originating from simultaneous trapping of two species. By comparing the trap loss from the Rb magneto-optical trap (MOT) in absence and presence of magnetically trapped ground state Cr atoms ...
Broomcorn seed (Sorghum vulgare) was used as raw material for bioethanol production. Optimum conditions were obtained from response surface method. Broomcorn seed flour (45 g/l) was treated by alkaline treatment and dual enzymatic hydrolysis (0.7 g/l of α- amylase and 0.42 g/l of amyloglucosidase). The hydrolyzed total sugar of 25.5 g/L was used in conventional bioethanol production (8.1 g/l) u...
Because of its simple body plan and ease of gene knockout and allele replacement, the moss Physcomitrella patens is often used as a model system for studies in plant physiology and developmental biology. Gene-trap and enhancer-trap systems are useful techniques for cloning genes and enhancers that function in specific tissues or cells. Additionally, these systems are convenient for obtaining mo...
Pheromone-baited traps are often used in ecological studies of the European corn borer, Ostrinia nubilalis (Hübner) (Lepidoptera: Crambidae). However, differences in trap captures may be confounded by trap design, trap location relative to a windbreak, and changes in local weather. The objectives of this experiment were, first, to examine differences in 0. nubilalis adult (moth) captures among ...
Dynamical behavior of particles in a Paul trap has been investigated by solving the set of differential equations considering the effect of damping force. Positions of the trapped ions as a function of time, ion trajectories and the phase space curves in the first stability region have been obtained in the presence of the damping force. The region of stability for r and z components as well as ...
