Nonfatal Injuries And Illnesses Among State And Local Government Workers

The scope of the Survey of Occupational Injuries and Illnesses was expanded with the 2008 survey to cover a more complete section of the U.S. economy: state and local government workers. Prior to the publication of the 2008 survey results, data users commonly requested information about industries in the public sector. Estimates covering nearly 18.5 million state and local government workers show that these public sector employees experienced a higher incidence rate of work-related injuries and illnesses than their private industry counterparts.This Spotlight on Statistics compares characteristics of injury and illness cases in state and local government with those in private industry, highlighting incidence rate trends in selected state and local government industries and examining injury and illness rates and cases that occurred in state and local government workplaces in 2011

“Missed Opportunity”: Operation Broadsword, 4 Brigade and the Gulf War, 1990–1991

The decision not to deploy 4 Canadian Mechanized Brigade (CMB) to participate in the Gulf War may eventually be of interest to students of Canadian defence policy. The current lack of available material on this subject will no doubt attenuate such efforts. The purpose of this article is to provide a brief, and very tentative, discussion of relevant factors contributing to the decision not to go. In essence, the following should be considered a “toe in the water” rather than a “headlong dive.

Incursion at Howz-e Madad: An Afghanistan Vignette

On 20 June 2007, Canadian and Afghan National Army forces supported by Dutch and American air forces conducted one of a series of incursions into the Zharey District west of Kandahar City. This incursion, called Operation SEASONS, was representative of operations undertaken in the summer of 2007 by the International Security Assistance Force (ISAF) in this area and is an evolution from how Canadian ground forces have been employed since they were re–introduced to the region in 2005. This account is based on the personal experiences of the author who observed these combat operations while they were in progress

The Mobile Striking Force and Continental Defence, 1948–1955

The need to project land force power within the confines of the northern portion of the North American continent may appear, at first glance, ridiculous in today’s world. In the early years of the Cold War, both Canada and the United States gave credibility to a land supported air threat to North America and took steps to meet such a contingency. The Canadian response was to configure the small, almost token, active Canadian Army into an airtransportable formation called the Mobile Striking Force (MSF). Some have suggested that the creation of the MSF and its operations in the 1948–1955 period was not only a waste of resources but distracted the Canadian Army from training for other, more important tasks which would become apparent in the 1950s.1 This may be an accurate assessment, but only in hindsight. The MSF did provide many positive benefits within the greater context of post-1945 Canadian defencec policy. The aim of this study is to examine the MSF’s organization, mission and planning in order to provide insight into these positive benefits

Dr. Strangelove Visits Canada: Project Rustice, Ease, and Bridge, 1958–1963

During the Cold War, many NATO governments developed highly secret contingency plans to maintain the continuity of government (COG) during and after nuclear attack. Canada was no exception. COG planning generally consisted of several elements including legal mechanisms and constitutional matters; document duplication and storage; skeleton bureaucracies; dispersion; transportation; and shelter. All were necessary to keep Canada functioning as a nation in the face of an attack by Soviet atomic and hydrogen bombs. The most misunderstood element of COG planning has been the shelter component. Critics of civil defence programmes argued that protecting government leaders in shelters and not providing similar facilities to the population as a whole was “undemocratic,” designed to maintain the “power elite.”1 The reality of Canada’s COG programme was quite different from this propaganda line and its ability to protect the country’s leaders in underground facilities was much more limited than alleged. This study will concentrate on the strategic context, physical arrangements and concepts of operation developed to maintain the continuity of Canadian government in the era of the greatest danger during the Cold War, 1958 to 1963

Operational Manoeuvre Group: Operation SOHIL LARAM II, Kandahar Province, February 2008

In February 2008 Regional Battle Group (South) in Afghanistan, based on The 1st Battalion, The Royal Gurkha Rifles supported by Canadian “enablers” and working with Afghan national security forces, conducted a mission known as Operation SOHIL LARAM II in the Maywand district of Kandahar province. A weak NATO presence coupled with a corrupt police force had allowed the Taliban to turn Maywand into a safe haven. Following the dismissal of the police force, Op SOHIL LARAM II was successful in disrupting Taliban operations, reasserting government authority and regaining the confidence of the local population. In addition, the disruption of Taliban forces allowed the relief in place of Canadian battle groups to proceed without the usual interference

Basic statistical analyses of candidate nickel-hydrogen cells for the Space Station Freedom

Nickel-Hydrogen (Ni/H2) secondary batteries will be implemented as a power source for the Space Station Freedom as well as for other NASA missions. Consequently, characterization tests of Ni/H2 cells from Eagle-Picher, Whittaker-Yardney, and Hughes were completed at the NASA Lewis Research Center. Watt-hour efficiencies of each Ni/H2 cell were measured for regulated charge and discharge cycles as a function of temperature, charge rate, discharge rate, and state of charge. Temperatures ranged from -5 C to 30 C, charge rates ranged from C/10 to 1C, discharge rates ranged from C/10 to 2C, and states of charge ranged from 20 percent to 100 percent. Results from regression analyses and analyses of mean watt-hour efficiencies demonstrated that overall performance was best at temperatures between 10 C and 20 C while the discharge rate correlated most strongly with watt-hour efficiency. In general, the cell with back-to-back electrode arrangement, single stack, 26 percent KOH, and serrated zircar separator and the cell with a recirculating electrode arrangement, unit stack, 31 percent KOH, zircar separators performed best

Mathematical modeling of solid oxide fuel cells

Development of predictive techniques, with regard to cell behavior, under various operating conditions is needed to improve cell performance, increase energy density, reduce manufacturing cost, and to broaden utilization of various fuels. Such technology would be especially beneficial for the solid oxide fuel cells (SOFC) at it early demonstration stage. The development of computer models to calculate the temperature, CD, reactant distributions in the tubular and monolithic SOFCs. Results indicate that problems of nonuniform heat generation and fuel gas depletion in the tubular cell module, and of size limitions in the monolithic (MOD 0) design may be encountered during FC operation
