Design And Construction

The purpose of this paper is to present a brief outline of the general engineering procedure for the siting and design of jetties and the methods of constructing such structures. After a general presentation of the formulae proposed by various engineers to determine the size and weight of individual pieces of stone or other material which should be used under various wave heights, this paper will be devoted principally to the construction of rubble stone jetties. This is the type principally used on the Pacific Coast of the United States.

Strategic Procurement

Henry Eccles, in classic studies on logistics, describes the dynamics of strategic procurement in the supply chain stretching from home countries to military theatres of operations. Naval authorities and industrialists concerned with Japanese aggression before and after Pearl Harbor looked towards developing shipbuilding capacity on North America’s Pacific Coast. The region turned into a volume producer of merchant vessels, warships and auxiliaries destined for service in the Pacific and Indian Oceans. Shipbuilding involved four broad categories of companies in the United States and Canada that enabled the tremendous production effort.

Geographic Remoteness

Among the immigrant groups which made a considerable contribution to the development of the United States and of the American way of life the Cornish people must be reckoned. Older accounts of the mining, camps of the Pacific Coast actually enumerate the “Cornish nationality” among the races that thronged to the gold and silver diggings. Yet, throughout the nineteenth century, British, census returns reveal that there were rarely more than a third of a million Cornish folk in the “old country”, and after 1861 their numbers declined. Yet this people impressed themselves upon the American scene, even on some of its most superficial observers, and this for a variety of reasons, apart from the local provincialisms created by geographic remoteness and physical difficulties of communication in the homeland until well into the “railway age”.

ABSTRACT All reported cases of WA1 babesiosis have occurred in the Pacific coast region of the United States, suggesting that WA1 is limited to this geographic area. However, we detected WA1 IgG in 27% of clinical sera sent to our laboratory for WA1 IgG testing from across the United States over a 2-year period, suggesting that exposure to WA1 or a closely related organism occurs outside Pacific coast states. We sought to determine if this high WA1 IgG detection rate among clinical specimens merely reflects WA1 seroprevalence outside the Pacific region. WA1 IgG, as well as Babesia microti IgG, was measured in 900 blood donor specimens from 9 states. Overall seroprevalence was 2.0% for WA1 and 0.4% for B. microti; regional seroprevalences ranged from 0 to 4% and 0 to 2%, respectively. Additional studies were performed to determine if WA1 IgG reactivity was attributable to polyclonal B-cell activation associated with acute Epstein-Barr virus (EBV) infection; 40 WA1 IgG-positive clinical sera and the 18 WA1 IgG-positive blood donor specimens were all negative for EBV capsid antigen (EBVCA) IgM (a marker of acute EBV infection), and 40 EBVCA IgM-positive sera were all negative for WA1 IgG. These findings indicate that the high WA1 IgG detection rate among clinical specimens does not simply reflect the national WA1 seroprevalence among blood donors or nonspecific reactivity due to acute EBV infection. Rather, the findings suggest that infection with WA1 or a related organism is more common than indicated by the literature and is not limited to Pacific coast states.
