A manual intended for use by those studying for the Oregon rights-of-way vegetation control exam. Includes chapters on basic weed science, vegetation management strategies; herbicides; factors influencing herbicide performance; special precautions when using herbicides; applying herbicides; calibration, mixing, and calculations; and application equipment. Includes a practice test, glossary, and references....
Certain 2- chioroethyl nitrosoureas have been demonstrated
to be highly specific inactivators of chymotrypsin
in vitro and glutathione reductase, both in vivo and in
isolated rat hepatocytes. The inactivation of glutathione
reductase in isolated hepatocytes resulted in an increased
sensitivity toward an adriamycin induced oxidative
challenge.
Prolonged incubation of 1-(2-chloroethyl)-3-([1-¹⁴...
“Making Connections” is about helping students see the “big picture”; to understand the web of overlapping causes and effects of attitudes, beliefs, actions, behaviors, and habits that connect people and the natural world in community. With these exercises, we hope students will become more aware of how their decisions affect...
In two studies we tested the effect of vitamin B-6
(B-6) intake on in vitro lymphocyte, proliferation and IL-2
production in healthy young women. In Study I, 6 women were
fed a constant diet containing 0.84 mg (4.96 μmols) of B-6
for 12 d, and 1.24 mg (7.33 μmols) and...
Embedded passives in multi-layer media have gained importance for offering an attractive solution to the implementation of off-chip passive components in RF and mixed signal circuits, especially for wireless applications. Among the passive devices, power dividers and combiners are extensively used for a host of applications including balanced mixers, phase...
In this paper, we use an interactionist perspective to study inter-industry variation in buying behavior. We argue that individual purchasers’ preferences for suppliers depend on three broad classes of variables: (1) The structure of the value chain stage in which the firm competes, (2) the firm’s competitive strategy and (3)...
A carburetor, such as is used on a gasoline engine, is
an appliance for vaporizing liquid hydrocarbons by atomizing
the liquid and mixing it with air.
This mixture of gasoline vapor and air is drawn into
the cylinder of'a gasoline engine, compressed and exploded
by means of an electric spark;...
Two studies were conducted to determine the effect of varying vitamin B-6 (B- 6) status on lymphocyte mitogenic response and pyridoxal 5'-phosphate (PLP) concentration in peripheral blood mononuclear cells (PBMC) in young women. In the first study, women were fed 1 mg/d for the first week and 1.5, 2.1 and...
A foundation for the control of tumors is presented,
based upon the formulation of a realistic, knowledge-based
mathematical model of the interaction between tumor cells
and the immune system. The parametric control variables
relevant to the latest experimental data, e.g., the sigmoidal
dose-response relationship and Michaelis-Menten dynamics,
are also considered....
This thesis presents two new approaches for the broadband, time-domain modeling of lossy transmission lines. Each approach is based on an alternative derivation of delay extraction in order to separate the line's linear phase from its
attenuation and dispersion. Augmentation networks represent the derived attenuation networks as rational function approximations....

With the increased attention on high efficiency and energy savings, power electronic energy conversion equipment is increasingly incorporated in all levels of the power system. The drawback of such equipment is the generation of nonsinusoidal currents in the power distribution network due to the nonlinear operation. Harmonic currents may distort...
