Second Mode Inclusion Claims in the Law Schools
During the past half-decade, law school student demands for changes in legal education to address issues of diversity and inclusion have both proliferated and grown insistent. Although the demands are somewhat varied, they have sometimes stretched far beyond the admission and hiring of more students and faculty from minority groups. Students have advocated for basic changes in the way that law schools operate in order to make them more inclusive of groups that have been historically marginalized within these institutions
The use of twin screw extruders for feeding coal against pressures of up to 1500 PSI
Recent tests with a twin-screw, co-rotating extruder which was successfully used to convey and feed coal against pressures of up to 1500 psi are described. Intermeshing and self-wiping, co-rotating twin-screws give greatly improved conveying and pressure built-up capabilities and avoid hangup and eventual decomposition of coal particles in the screw flights. The conveying action of intermeshing, self-wiping, co-rotating extruder systems approaches that of a positive displacement pump. With this feature, it is possible to maintain very accurate control over all aspects of product conveyance in the extruder, i.e., intake, conveyance and pressure buildup
A study of the sonic-boom characteristics of a blunt body at a Mach number of 4.14
An experimental and theoretical study has shown that the applicability of far-field sonic-boom theory previously demonstrated for more slender shapes may now be extended to bodies with ratios of diameter to length as great as 2 and to Mach numbers at least as high as 4.14. This finding is of special significance in view of the limitations to the use of existing methods for the extrapolation of close-in experimental data
Estimation of wing nonlinear aerodynamic characteristics at supersonic speeds
A computational system for estimation of nonlinear aerodynamic characteristics of wings at supersonic speeds was developed and was incorporated in a computer program. This corrected linearized theory method accounts for nonlinearities in the variation of basic pressure loadings with local surface slopes, predicts the degree of attainment of theoretical leading edge thrust, and provides an estimate of detached leading edge vortex loadings that result when the theoretical thrust forces are not fully realized
Separation of two bodies in space
Computer program analyzes the motion of two rigid bodies in space, separating as a result of any one, or a combination of, the following mechanisms - springs with ball ends, springs with one end guided, pyrotechnics, rockets, cold-gas jets, air pistons, and Coulomb drag
Evaluation of copper slag blast media for railcar maintenance
Copper slag was tested as a blasting substitute for zirconium silicate which is used to remove paint from railroad cars. The copper slag tested is less costly, strips paint faster, is produced near the point of need, provides a good bonding surface for paint, and permits the operator to work in a more comfortable position, i.e., standing nearly erect instead of having to crouch. Outdoor blasting with the tested Blackhawk (20 to 40 mesh) copper slag is also environmentally acceptable to the State of Utah. Results of tests for the surface erosion rate with copper slag blasting are included
Supersonic wings with significant leading-edge thrust at cruise
Experimental/theoretical correlations are presented which show that significant levels of leading edge thrust are possible at supersonic speeds for certain planforms which match the theoretical thrust distribution potential with the supporting airfoil geometry. The analytical process employed spanwise distribution of both it and/or that component of full theoretical thrust which acts as vortex lift. Significantly improved aerodynamic performance in the moderate supersonic speed regime is indicated

Bringing the Law Back into the History of the Civil Rights Movement
It is a pleasure to comment on Nancy MacLean's hugely important book Freedom is Not Enough: The Opening of the American Workplace as an example of what I might call “bringing the law back in” to the history of the civil rights movement. A generation ago, the idea that law needed to be introduced into this history would have seemed nonsensical. At that time, law provided one of the central touchstones in the historical narrative of the struggle for racial equality in American life. Scholarship in this area built on C. Vann Woodward's pioneering work on the rise of Jim Crow, which itself was written shortly after Woodward's participation in the Brown v. Board of Education litigation. The dominant narrative began with the legal construction of Jim Crow in the late nineteenth century and continued with the founding of the NAACP. Other actors came along at various points in the story, prominent among them New Deal–era racial liberals, World War II–era activists, midcentury social scientists, Southern civil rights leaders and movements, and eventually black power. The end point was marked by the litigation and legislative victories of the 1950s and '60s, which finally wrote back into law what had been taken away by segregationist white Southerners and a compliant Supreme Court in the late nineteenth century. The implicit methodological take on law was that state and federal statutes, as well as court decisions, provided an important impetus, or at the very least a validation, for racial change—first for white Southerners as they created the Jim Crow legal regime and later for segregation's opponents as they reinscribed racial equality onto the core narrative of American life
