Abstract
Understanding the effects of climate change on forest ecosystems requires exploration of the relationships of different components of the system, such as the response of biota to local hydrology, temperature, precipitation, and elevation. The Long-term Ecological Research Program at the H. J. Andrews Experimental Forest, located in the Western...
Hatcheries are used to produce salmon to augment the number of fish available for harvest, and to supplement wild populations that may be threatened with extinction. Although traditional hatchery rearing methods can produce many fish, they can pose risk to wild populations because they tend to produce salmon with lower...
Modifications of histone tail amino acid residues are necessary for many reactions involving chromatin. These processes can produce transcriptionally active, euchromatic, or inactive, heterochromatic, segments of DNA. The formation and maintenance of facultative heterochromatin is critical for the proper growth and development of many eukaryotes. Euchromatin can be changed into...
As scientific technologies and techniques have improved in past decades, it has become
possible to quickly collect unprecedented quantities of experimental data. In the study of gene expression, for instance, datasets comprising tens of thousands of variables and hundreds of treatments can be produced in a matter of months. When...
We developed an integration-based line detection algorithm. Existing line detection methods such as the Hough Transformation (HT) and its variants are insensitive to image noise. The reason is that HT finds lines by calculating the gradient of the image and assumes that the region where the gradient is the steepest...
As responsible energy usage is becoming more and more a part of the public conscience, a key practice of this idea emerges. Specifically, using the energy we do have with maximum efficiency. While the laws of thermodynamics remain a limiting factor, research has been done to show that properties of...
STEM education is delivered to K12 audiences by Pre-college Programs across the nation, many of which serve underrepresented and underserved students as part of their core missions. While there is robust attention to STEM curriculum development and college connection events in such programs, few have social-cultural aspects of learning as...
"The house does not make the home, but it has a
great deal of influence on the health and character of
the family.
In planning a house, its special uses must be considered.
The house intended for a home should be made
s convenient, sanitary and attractive as possible.
The...
This machine Is the first series arc machine installed
In the city of Portland. It was obtained by
the Electrical Department of O.A.C., with the object
of rewinding it for a high current machine to be used
in the charging of storage batteries.
The author has not previously had any course in
House Construction, but the inspiration for the these
was received from having seen the work done by a class
in that subject. The plans for the house, with the windows,
doors, cupboards in the kitchen, fireplaces, some
of the furniture and...
Any woman's wardrobe is important, as it is to a
great extent an indication of her character. A High
School teacher, holding the position she does, as a director
of the aims and ideals of young girls must be especially
careful in her dress. Her clothing should be
neat, well...
Since 1935, France has introduced a set of strict national wine rules and regulations, the Appellation d’Origine Contrôlée (AOC). The AOC limits fraud and oversees quality control by basing the rules on terroir. High quality from terroir comes has both physical and cultural factors. Before 1935, France produced a variety...
Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...
This course of study has been planned for the
seventh and eighth grades in Oregon schools. One period
each week, or ninety minutes or more, is needed.
The study or cookery should be closely correlated with
the other school branches. High ideals of workmanship,
neatness, accuracy and skill should be...
The curriculum of technical degrees at higher education institutions in the United States needs to continuously adapt to ever changing technologies. One way to accomplish this is to adopt a more dynamic approach that separates the practical and theoretical components of the university education, and where the student concentrates on...
Riparian areas are an integral component of fluvial ecosystems. The management of Oregon's riparian areas has come under greater scrutiny since that latest revision of the Oregon Forest Practices Act (1994). Many riparian areas lie within forested areas. Riparian management issues such as anadromous fish population decline and large woody...
Anaerobic digestion is a common terminal step in wastewater treatment systems and produces valuable by-products such as biogas, a combination of carbon dioxide and methane. Biogas can be used to off-set energy costs, and along with the anaerobic co-digestion of fats, oils, and greases (FOG) has been found to increase...
This study examined how different urbanization patterns in France and the United States influenced the development of their respective housing markets. More specifically, the study analyzed the evolution of housing size in France and the United States during the 20th century. Descriptive statistical analysis and regression models were used to...
The pharmacy practices in Ecuador and the United States are different on three different levels: culturally, educationally and governmentally. Research was conducted to compare and contrast the differences of community pharmacy practices between the United States and Ecuador. Eight different pharmacists in Quito were interviewed with a series of questions....
Few discoveries of any importance have been the result of a moment's happy coincidence; rather have they been the fruit of many hours of tedious thought and experiment. This is especially true in the realm of organic chemistry. Here, where progress is made only by the most painstaking experimentation, extensive...
Autonomous buoys were deployed in 2011 in the central Arctic: An Ice-Tethered Profiler (ITP) and Ice Mass Balance (IMB) buoys were deployed in the Makarov basin; a Polar Ocean Profiling System (POPS) and Ice Thickness (Ice-T) buoy were deployed on the Eurasian Basin. The two different sites were approximately 70km...
