Forensic Investigations In Alaska

Forensic Engineering In Alaska Involves The Same Type Cases As It Does Outside - Personal Injury, Auto And Industrial Accidents, Fires, Soil And Foundation Failures, Faulty Construction, Construction Claims, Errors And Omissions, Etc. We Do Have Elements Which Add To The Complexity Of These Typical Cases. They Are: Engineering In The Arctic, And Dealing With Permafrost. These Are So Critical And Unique To Alaska, That One Of The Requirements For Registration In The State As An Engineer Or Architect Is An Understanding, Satisfactory To The Registration Board, Of These Elements. This Requirement Must Be Met By Writing A Comprehensive Treatise On Construction Under Arctic And Subarctic Conditions, Or Successful Completion Of A One Semester, Graduate-Level, Course In Arctic Engineering At The University Of Alaska, Or Of A Seminar On Arctic Engineering Approved By The Board. No Seminars Have Been Approved, To My Knowledge. I Thought That It Would Be Of Interest If I Related One Of My Cases Which Involved The Arctic Environment. It Is Not An In-Depth Study Of Arctic Conditions But A Part Of The Problem As It Arose.

Critical and Strategic Minerals Investigations in Alaska: Chromium: ABSTRACT

The Bureau of Mines investigated chromite deposits and occurrences in Alaska between 1979 and 1984 as part of the Bureau's critical and strategic minerals program. Beneficiation and mineralogical characterization tests were performed on 68 samples. Chromite-bearing ultramafic rocks occur in eight regions in Alaska. One hundred sixty-one subeconomic podiform-type deposits and one placer deposit are estimated to contain 3.4-4.7 million tons of chromic oxide (Cr2O3) in high-chromium and high-iron chromite. In most cases, mine-site beneficiation would be required to produce shipping-grade concentrates. In the Chugach trend, an inferred reserve base comprises 2.8 million tons of Cr2O3 in 42 deposits that are all within 10 mi of tidewater or existing transportation routes. Most of these are indicated reserves (1.8 million tons) contained in the newly discovered Turner stringer zone and End_Page 664------------------------------ Windy River placer deposit at Red Mountain and inferred reserves at the Halibut Bay complex on Kodiak Island. Seventy less-accessible deposits in the remote western Brooks Range contain between 0.6 and 1.4 million tons of high-chromium chromite. The Rampart, Yukon-Koyukuk, and Alaska Range trends and the southeast Alaska region contain deposits with minor production potential. End_of_Article - Last_Page 665------------

Late Wisconsin and Recent History of the Matanuska Glacier, Alaska

Reports studies of this glacier in the upper Matanuska valley in 1953, 1954, and 1957, as part of the U.S. Geological Survey terrain and permafrost investigations in Alaska. Advances and retreats of the glacier, indicated by moraines and marginal channels, were traced. The results are outlined amplifying the preliminary report, No. 56057.

Archaeological investigations in Alaska since 1939

In almost any branch of science, periods of slow and steady progress or stagnation alternate with periods of rapid development caused by new discoveries or inventions, by the introduction of new methods, or by other accelerating factors. Eskimo archaeology is no exception to this rule and, even if only thirty years have passed since archaeologists first began to search for Eskimo relics, it is already possible to distinguish four periods of development, separated by short interludes of relatively little activity. Of these four periods only the last two fall within the scope of this article, but since the understanding of recent developments in Eskimo archaeology presupposes a knowledge of previous work in that field it is necessary to summarize what was accomplished in the first two periods.

A Preliminary Note on Trichinosis Investigations in Alaska

Brief account of research by the U.S. Public Health Service, Alaska, beginning in 1949, which revealed infections in the polar bear, arctic and red foxes, white whale, Eskimo dog, brown and grizzly bears, wolf and wolverine, after nearly all species of land carnivores in Alaska had been examined.
