Non-process elements are present in all kraft
recovery systems. Non-process elements are defined as
those elements which are not essential to the chemical
process, i.e., are neither active pulping chemicals (e.g.,
NaOH and Na₂S in the kraft process), nor compounds present
as a result of incomplete conversion of makeup chemicals...
A survey of the pulping literature indicated
that although the kinetics of the Kraft Pulping
process has been studied in detail , very few studies
have been reported for Alkaline Sulfite /
Anthraquinone (ASAQ) pulping process. There is no
existing rate model for this pulping process. Hence,
the objectives of...
Various types of mass movement features are found in the drainage
basin of the East Fork Coquille River in the southern Oregon Coast
Range. The distribution and forms of mass movement features in the area
are related to geologic factors and the resultant topography.
The Jurassic Otter Point Formation, a...
Seven sites of uniform topography and soil were selected within
a self perpetuating ponderosa pine forest found on the eastern
flank of the central Oregon Cascades. These plots were located along
a vegetational gradient caused mainly by an orographic rain shadow.
Data gathered included density, frequency, and cover for all...
Twenty sites of uniform topography and soil were select ed in the
montane forest found on the East flank of the Central Oregon Cascades.
These sites were located along a vegetational gradient composed of
five plant communities: Abies/Pachistima, Pinus/Ceanothus, Pinus
Arctostaphylos-Purshia, Pinus/Purshia/Festuca, and Juniperus
Festuca. An attempt was made to...
A free-air gravity anomaly map of the area between 10°-17°N and
90°-101°W shows distinctive positive and negative anomalies which
parallel the Tehuatepec Ridge. The positive anomaly approximately
overlies the topographic expression of the ridge. On the wide continental
shelf southeast of the Gulf of Tehuantepec a positive gravity
anomaly with...
