Since the establishment of the Independence of the Latin-
American States, no year has passed in which they did not increase their
trade relations with foreign nations. The prominence given to the Third
International Conference of the South American States; the postponement
of The Hague Peace Conference; the subsequent appointment...
In presenting this thesis it will probably be necessary
for me to qualify the usefulness of the paper I am writing.school of
At first glance it would seem to be just a mere recording of
the progress of forest fire protection in recent years and,
as such, to have no...
The rapid advancement of electrical science has led it to invade
the field of marine engineering. On ship-board, all ship's lights,
search lights and signal lights are entirely electric. Of power appliances
outside of uses on men of war,ship's ventilation is completely
electric; electric deck winches and boat cranes are...
HafSOx is a dielectric material that also functions as an insulator. It is able to be spin-coated onto a silicon substrate, creating a thin, amorphous film. It is very dense, which helps lead it to a high dielectric constant, making it ideal for electronic devices through the use of lithography....
This gamma irradiation study was conducted to establish an LD50 of the hop (Humulus lupulus L.) cultivar Cascade . The overall, long term goal is to generate replacement hop cultivars by inducing minor but significant DNA alterations with gamma radiation to improve agronomic quality without changing the brewing profile. The...
Being present in an area of play can create a dynamic experience of exploration, movement, and interaction with objects and peers. These are required to foster positive development across cognitive, social, and physical domains (1).
Children with disabilities may experience limitations in mobility impacting their early exploration, socialization, and play...
Respiratory Syncytial Virus (RSV) is a major concern in infants, the elderly, and immunocompromised individuals. There is currently no vaccine available. While it causes a significant number of hospitalizations and complications, RSV is a thermo labile virus and not very stable in the environment. This matter complicates the creation of...
Zinc is an essential micronutrient required for many cellular functions, including
the development and function of the immune system. The biological consequences of
zinc deficiency illustrate the significance of zinc in human health. Zinc deficiency has
been shown to cause the dysregulation of both innate and adaptive immune responses, as...
During the past year the rapid increase in the cost of copper and aluminum has led operating companies to investigate the feasibility of using iron and steel conductors for transmission and distribution purposes where small blocks of power are to be served. This Thesis gives the results of tests on...
The question of whether to purchase power or to
maintain an isolated plant is one which frequently
confronts the engineer, and the problem is by no means
easy of solution, as there are a number of factors
which vary with individual cases and determine the
economy and desirability of the...
Foreign occupation and extraction have arguably existed since the very emergence of interstate conflict millennia ago. Yet despite humanity’s vast experience on the topic, we know surprisingly little about its long-term economic consequences. It is generally accepted by most that the extraction of resources by a foreign power tends to...
Biological introductions may considerably alter the composition and community dynamics of invaded areas thereby changing many ecosystem processes including productivity, decomposition, nutrient cycling and hydrology. The effects on native species may be obscured by a lack of information on distribution and abundance patterns. The Japanese eelgrass, Zostera japonica, was introduced...
Micro-organisms are a distinct class of unicellular vegetable organisms placed under the general name of bacteria instead of trying to affix either algae or fungi to this class of living beings. These microorganisms are divided into two classes; pathogenic and non-pathogenic bacteria. The pathogenesis is determined by inoculating a susceptible...
Probably no other process of such importance is so
little understood as that which takes place within our
own bodies. We know that we drink water and are refreshed, eat a meal and are strengthened, that the food
we consume is in some way converted into living tissue;
but the...
The preceding empirical research examines the traditional and evolutionary research surrounding youth deviance. Deviance is routinely discussed as an adverse impact in a plethora of theories and it is imperative to further develop the knowledge of deviance as society progresses. In this report, the utilized sample group approximately (n=13583) was...
The most interesting study connected with the
development of the American novel is the accompanying
feature of the growth of the country itself. In a
certain way the changes seem peculiar, but in another
way they are exactly what we might be led to expect.
In tracing the development from...
By way of preface, a few words may be said regarding the advantages of the revolving field type of machine.
The first in its favor and the chief reason for its
existence, is that by passing the heavy armature current
through permanent stationary contacts and only the small
field current...
The marked movement of utilizing Oregon's water power
in the service of generating electric current, has been promoted
by the economics in transmission of electricity to distances
both great and small; by the harnessing of industrial
implements to electric power; and by the advancement and extension
of interurban railways.
It...
Throughout the year the regular design work of the
class room proved so profitable that it was thought that
there was no subject which could be selected for thesis
purposes of greater benefit,or which offered as great a
latitude in the working out of the various problems, than
the one...
A feasible development for a Hydro-Electric power
plant can be found in the Mary's River. About 9 miles
west of Corvallis, the north fork of the stream affords
an excellent situation for a dam site. The canon of
the north fork at this point is very narrow, and having
good...
The electric motor has for an number of
years occupied an important position in the operation
of wood-working machinery, of moderate capacity, for
example the planing mills, sash and door factories
and many of the other similar wood working shops.
However its adoption in the more trying field of saw...
In designing a machine of any kind, considerations
must be made regarding the kind and amount of work
it will be required to do, the foundation for its support,
and the amount of space available for its occupancy.
An engine which is to be used for driving an automobile
must...
By an appropriation of the Oregon Legislature of it becomes possible for the Oregon Agricultural College to build a drill shed, a thing long needed by this institution. Dennis, Hendricks and Tobey, architects of Portland, submitted plans for this drill shed and in designing the truss for this building we...
One of the most important and likewise practical problems that oonfront
the Electrioal Engineers of the present daysis the design and the
construotion of Hydro Electrio Power plants for the generating of electrioal
energy,both for power and li;hting purposes. In order that we
might become better acquainted with the facts...
The design and specification of a dwelling house
constitutes the thesis of the student Arvid Anderson
of the class of '08.
This thesis consists of two parts, namely: drawings
and written description or specification. The drawings
and specifications are to be considered as cooperative,
the latter are necessary to express...
"Of all the different types of sail boats used for pleasure on western inland waters, the 'skip-jack' seems to be the general favorite. This style of boat is known by many names such as 'skip-jack', 'lark', 'skimming-dish', etc., and they are so called from the manner in which they ride...
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;...
