The effect of the conjugation with cyclopropyl rings
on the activation parameters for the formation of
carbenes from the corresponding diazo compounds was
investigated using diisopropylcarbene (46), cyclopropyl-isopropylcarbene
(47), and dicyclopropylcarbene (48).
Each of these three carbenes was generated by the
thermolysis of the parent benzenesulfonylhydrazone
potassium salts using DMSO...
An hierarchically structured resource flow competition model
for two species is developed. The model is shown to be
intrinsically neutrally stable with a dynamical behavior
derived from perturbation responses. The model properties
are contrasted with those of a conventionally interpreted
Lotka-Volterra competition model.
A simulation developed from the model is...
COLAN (Control Oriented Local Area Network ) is a
redesign of the Task-Master, a daisy-chain structure
distributed control system. COLAN is a simple bus structure
communication subnetwork intended for distributed control
applications. Low cost and simplicity are two main design
criteria. Point-to-point and broadcast communications are
possible. A packet switching...
The extensive and expanding use of radioactive materials
(RAM) in the production of power, industry, the healing
arts, and various branches of research has inevitably
resulted in a sizable increase of hazardous material
transportation in the state of Oregon. The location of the
Hanford facility just north of the Oregon...
Beer, nonfat dry milk, fried bacon and microwave baked fish were
treated under simulated gastric and extreme nitrosation conditions to
estimate their capacity for generation of endogenously formed
N-nitrosamines. The level of nitrosamines in beer increased from 0.1
ppb N-nitrosodimethylamine to 0.4 ppb N-nitrosodimethylamine (p < 0.05) under simulated gastric...
A previous altimeter wind speed retrieval algorithm was developed on the basis of wind speeds in the the limited range from about 4 to 14 ms¯¹. In this paper, we use a new approach which gives a wind speed model function applicable over the range 0 to 21 ms¯¹. The...
