‘DEATH OF A UNION MAN’: RECONSTRUCTING CONFLICT AT WINDSOR CHRYSLER DURING THE LONG SEVENTIES

The shooting of UAW Local 444 President Charles “Charlie” Brooks in January 1977 by former Chrysler worker Clarence Talbot, allegedly over a grievance, brought the city of Windsor, Ontario to a standstill. Recently fired from his position as a relief worker at the Chrysler plant, Talbot was in a very vulnerable position where his ability to survive hinged on a successful grievance. Brooks was a beloved labour leader noted for his radical and colourful ways who had a long history of working hard for union and community members through his advocacy. The Ontario Supreme Court ultimately declared Talbot not criminally responsible by reason of insanity resulting in an indefinite rehabilitory sentence to a mental asylum. These men’s lives and Brooks’ death can be better understood by historically examining the systems that surrounded them, especially by examining the social forces that shaped the expectations placed on them by their communities. Using academic sources and newspaper accounts of these events, this paper seeks to analyze factors that may have contributed to the shooting and the context in which it occurred. At a time when discussions of labour rights, civil rights and the criminal justice system are once again enflamed, this story seems especially apt for re-examination

Unparticle effects on cosmic ray photon and e±e^\pm

We study the effects of unparticle physics on the cosmic ray photon and $e^\pm$, including on the pair production (PP) and elastic scattering (ES) of cosmic ray photon off various background radiations, and on the inverse Compton scattering of cosmic ray $e^\pm$ with cosmic radiations. We compute the spin-averaged amplitudes squared of three processes and find that the advent of unparticle will never significantly change the interactions of cosmic ray photon and $e^\pm$ with various background radiations, although the available papers show that ES which occurs in the tree-level through unparticle exchanges will easily surpass PP in the approximate parameter regions.Comment: 13 pages, 7 figure

Three-dimensional Navier-Stokes heat transfer predictions for turbine blade rows

Results are shown for a three-dimensional Navier-Stokes analysis of both the flow and the surface heat transfer for turbine applications. Heat transfer comparisons are made with the experimental shock-tunnel data of Dunn and Kim, and with the data of Blair for the rotor of the large scale rotating turbine. The analysis was done using the steady-state, three-dimensional, thin-layer Navier-Stokes code developed by Chima, which uses a multistage Runge-Kutta scheme with implicit residual smoothing. An algebraic mixing length turbulence model is used to calculate turbulent eddy viscosity. The variation in heat transfer due to variations in grid parameters is examined. The effects of rotation, tip clearance, and inlet boundary layer thickness variation on the predicted blade and endwall heat transfer are examined

Comparison of the heat transfer efficiency of nanofluids

The continuously increasing power involved in many applications, coupled with the very small size of a number of component devices, is pushing the technical community to look for more efficient heat transfer systems, to remove the heat generated and keep the system under controlled operating conditions. In particular, significant interest has been devoted to the use of the so-called nanofluids, obtained by suspending nano-sized particles in conventional heat transfer liquids. According to some literature, these suspensions present enhanced heat transfer capabilities, without the inconveniencies of particles settlement and clogging of the channels encountered using larger particles. However, other results show that the actual improvement in the heat transfer efficiency may depend on the adopted working conditions and on the reference parameters (fluid velocity, Reynolds number, pressure drop, etc.) assumed to compare the performances of the nanoparticles suspensions with those of the clear thermal fluid. In the present work heat transfer experiments were carried out on a number of nanofluids systems, varying the type and the concentration of the nanoparticles, and the fluid dynamic regime. The investigated suspensions gave rise to heat transfer coefficients different from those of their respective clear thermal fluid, the thermal efficiency being higher or lower, depending on the fluid dynamic parameter used as a base for comparing the systems. Generally speaking, in most cases nanofluids may give an advantage from the heat transfer point of view only when the conditions are unfavorable for the traditional thermal fluid

Modelling of shaded and unshaded shallow-ground heat pump system for a residential building block in a Mediterranean climate

Heat pumps may be coupled to shallow-ground geothermal fields and used for the purpose of space heating and cooling of buildings. However, quite often it is not possible to locate the geothermal field in cleared grounds, especially in cities where building density is high and land has a high premium. This leads to the possibility of burying the geothermal field under the basement of new building blocks, before construction of the building. In the present work, the shaded-unshaded arrangement is numerically studied by coupling the software DesignBuilder-EnergyPlus to assess the building's energy requirement with the software FEFLOW to solve the heat transfer equation in porous media. Assuming a standard residential building block, the coupling between the two software is performed by assigning the thermal energy requirement for air conditioning, as calculated by EnergyPlus, to a flat-panel typology of ground heat exchanger simplified in a 2D FEFLOW's domain. The results show that it is necessary to opt for a dual-source heat pump (air/geothermal) system to ensure that the ground is not frozen or over-heated at peak times and to improve the overall performance of the system.peer-reviewe

Cooling system for high speed aircraft

The system eliminates the necessity of shielding an aircraft airframe constructed of material such as aluminum. Cooling is accomplished by passing a coolant through the aircraft airframe, the coolant acting as a carrier to remove heat from the airframe. The coolant is circulated through a heat pump and a heat exchanger which together extract essentially all of the added heat from the coolant. The heat is transferred to the aircraft fuel system via the heat exchanger and the heat pump. The heat extracted from the coolant is utilized to power the heat pump. The heat pump has associated therewith power turbine mechanism which is also driven by the extracted heat. The power turbines are utilized to drive various aircraft subsystems, the compressor of the heat pump, and provide engine cooling

Sparking a change: Three years ago, Dzameer Dzulkifli founded Teach For Malaysia out of a desire to improve Malaysia's state of education and a passion for developing local talent. Today he faces the challenges of growing the organisation and addressing the criticism levelled against it.

WHETHER it is the flip-flopping of the medium of instruction in national schools or the debatable quality of teachers, the state of education in Malaysia is a hot button issue at every mealtime conversation.It was no different for colleagues Dzameer Dzulkifli and Keeran Sivarajah, who were discussing how to improve education in Malaysia during a mamak session in 2009.However, unlike others who merely air their dissatisfaction, they decided to act upon it

Numerical Study on Transient Heat Characteristics of a Rectangular Latent Heat Storage Vessel

Transient characteristics of the rectangular latent heat storage vessel packed with shape-stabilized phase change (solid-liquid) material (PCM) are investigated numerically by solving the governing equations of both the PCM and the heat transfer medium(water) simultaneously as a conjugate problem with the finite difference technique. It's found that the heat storage characteristics are greatly affected by the flow direction of the heat transfer medium since the natural and forced convection coexists in the heat storage vessel. That is, it is classified that the effectively thermal efficiency of the latent heat storage system is obtained by the downflow along vertical PCM for heat storage process and the upflow for heat release process. The effect of the inlet velocity of heat transfer medium(water) on transient heat characteristics of the latent heat storage system is also revealed in the present study
