    What is Gun Control? Direct Burdens Incidental Burdens, and the Boundaries of the Second Amendment

    Particularly in places with few recognizable gun control laws, “gun neutral” civil and criminal rules are an important but often-unnoticed basis for the legal regulation of guns. The burdens that these rules impose on the keeping and bearing of arms are at times significant, but they are also incidental, which raises hard questions about the boundaries between constitutional law, regulation, and legally enforceable private ordering. Does the Second Amendment apply to civil suits for trespass, negligence, and nuisance? Does the Amendment cover gun-neutral laws of general applicability like assault and disturbing the peace? In the course of addressing these practical questions and the broader conceptual challenges that they represent, this Article fashions analytic tools that may be useful to a wide range of constitutional problems

    Lethality, Public Carry, and Adequate Alternatives

    Get PDF
    This Article explores the relationship between lethality and the right to bear arms, and considers how that relationship might be shaped by the availability of non-lethal alternative weapons. Prior scholarship has asked whether the Second Amendment includes a right to carry non-lethal “Arms.” An important set of related questions remains: does the Second Amendment necessarily include a right to arm oneself publicly with lethal force, if non-lethal alternatives are available? And how should one evaluate the adequacy of those alternatives

    Evaluation of selected chemical processes for production of low-cost silicon, phase 3

    A Process Development Unit (PDU), which consisted of the four major units of the process, was designed, installed, and experimentally operated. The PDU was sized to 50MT/Yr. The deposition took place in a fluidized bed reactor. As a consequences of the experiments, improvements in the design an operation of these units were undertaken and their experimental limitations were partially established. A parallel program of experimental work demonstrated that Zinc can be vaporized for introduction into the fluidized bed reactor, by direct induction-coupled r.f. energy. Residual zinc in the product can be removed by heat treatment below the melting point of silicon. Current efficiencies of 94 percent and above, and power efficiencies around 40 percent are achievable in the laboratory-scale electrolysis of ZnCl2

    LSA silicon material task closed-cycle process development

    The initial effort on feasibility of the closed cycle process was begun with the design of the two major items of untested equipment, the silicon tetrachloride by product converter and the rotary drum reactor for deposition of silicon from trichlorosilane. The design criteria of the initial laboratory equipment included consideration of the reaction chemistry, thermodynamics, and other technical factors. Design and construction of the laboratory equipment was completed. Preliminary silicon tetrachloride conversion experiments confirmed the expected high yield of trichlorosilane, up to 98 percent of theoretical conversion. A preliminary solar-grade polysilicon cost estimate, including capital costs considered extremely conservative, of $6.91/kg supports the potential of this approach to achieve the cost goal. The closed cycle process appears to have a very likely potential to achieve LSA goals

    Competing for Refugees: A Market-Based Solution to a Humanitarian Crisis

    Get PDF
    The current refugee crisis demands novel legal solutions, and new ways of summoning the political will to implement them. As a matter of national incentives, the goal must be to design mechanisms that discourage countries of origin from creating refugees, and encourage host countries to welcome them. One way to achieve this would be to recognize that persecuted refugee groups have a financial claim against their countries of origin, and that this claim can be traded to host nations in exchange for acceptance. Modifications to the international apparatus would be necessary, but the basic legal elements of this proposal already exist. In short, international law can and should give refugees a legal asset, give host nations incentives to accept them, and give oppressive countries of origin the bill

    Progress from October 1, 1977, through December 31, 1977, is reported in the design of the 50 MT/year experimental facility for the preparation of high purity silicon by the zinc vapor reduction of silicon tetrachloride in a fluidized bed of seed particles to form a free flowing granular product

    Symmetry-breaking in chiral polymerisation

    Get PDF
    We propose a model for chiral polymerisation and investigate its symmetric and asymmetric solutions. The model has a source species which decays into left- and right-handed types of monomer, each of which can polymerise to form homochiral chains; these chains are susceptible to `poisoning' by the opposite handed monomer. Homochiral polymers are assumed to influence the proportion of each type of monomer formed from the precursor. We show that for certain parameter values a positive feedback mechanism makes the symmetric steady-state solution unstable. The kinetics of polymer formation are then analysed in the case where the system starts from zero concentrations of monomer and chains. We show that following a long induction time, extremely large concentrations of polymers are formed for a short time, during this time an asymmetry introduced into the system by a random external perturbation may be massively amplified. The system then approaches one of the steady-state solutions described above.Comment: 26pages, 6 Figure
