The spectral design and fabrication of cooled (7K) mid-infrared dichroic beamsplitters and bandpass filter coatings for the MIRI spectrometer and imager are described. Design methods to achieve the spectral performance and coating materials are discussed

CORPORATIONS-\u27\u27FAIR PLAN UNDER SECTION 77B-APPLICABILITY OF \u3cem\u3eBoyd\u3c/em\u3e CASE

Few controversies can arise that present so many variables and require such delicate balancing of not easily ascertainable economic and legal interests as the one occurring when it becomes necessary for a court to pass on the fairness of a reorganization plan. The recognition of this is clearly seen in the provision of Section 77B of the Bankruptcy Act which reads in part: after hearing such objections as may be made to the plan, the judge shall confirm the plan if satisfied that it is fair and equitable and does not discriminate unfairly in favor of any class of creditors or stockholders and is feasible. The problem presented is obvious although it seems possible to phrase it in several ways. To what extent must the court today go back to the Boyd case and its successors in determining whether the reorganization plan is fair and equitable? Can it be argued that Congress intended this provision to set up a new standard of fairness? Is the problem of the fair plan under Section 77B in any way a new one? Although the form of these questions could be varied indefinitely, it is felt that answers to these will furnish a background against which the chief difficulties can be resolved

Types of religious certainty implied by Kant's treatment of the problem of God

Thesis (Ph.D)--Boston UniversityIn the light of the thought of Immanuel Kant is there any justifiable certainty (particularly of God's existence)? This problem involves the subordinate problem: can logical certainty and psychological certainty (certitude) be correlated, i.e. is an empirical theology possible? Kant's treatment of the problem of God suggests three types of religious certainty or certainty-claims--theoretical, moral and experiential. In his Kritik der reinen Vernunft, Kant exposed the weaknesses of the traditional theistic arguments as claims to logical or theoretical certainty. Partly as a consequence, there is today a general dissatisfaction with the traditional theistic "proofs." As merely theoretical, they are abstract, the results of belief rather than producers of it, having some value but producing no high degree of logical certainty. In his Kritik der praktischen Vernunft and Kritik der Urtheilskraft, Kant elaborated upon the idea advanced in the first Critique that what can not be demonstrated by the speculative reason can be held as a reasonable belief by the practical reason. He viewed God as the Summum Bonum, Supreme Intelligence, who must exist if the happiness of the good is to be guaranteed, as such a guarantee necessitates harmony between the moral and physical orders, a harmony only possible in their union under one Ruler. In aesthetic experience, also, Kant saw an implication of God's existence, for he put the intuitive judgments of the holy and of a teleological universe upon the same plane as the immediate apprehensions of the beautiful and the sublime, all judgments of the practical reason. The chief conolusions reached are as follows: 1) There seems to be no reason for the denial of certainty of any kind and of any degree. 2) On purely theoretioal grounds, there is no high degree of certainty in religious matters. 3) Certitude of the existence of God is both desirable and reasonable. 4) Practical certainty (certitude) of His existence is possible on the basis of the "moral" argument. 5) There is a higher degree of certitude in the experiential approach to God. 6) The synoptic view, comprising theoretical, moral, experiential and pragmatical aspects of religious Reality, is a coherent view. 7) The certainty resulting from the correlation of certainty and certitude in this view, while not absolute, is adequate for the individual and for a rational-empirical theology.

The chloride volatilization of silver and lead from zinc concentrate

The Yellow Pine mine at Goodsprings, in southwestern Nevada, yields an ore nearly free from gangue constituents. The ore as mined contains 8 to 12 per cent lead, 8 to 12 ounces silver, and 30 to 35 per cent zinc, and is milled in a gravity concentration plant where separation of the lead and zinc is made. The ore is nearly all carbonate, except a small amount of galena, and the lead concentrates contain considerable zinc; the zinc concentrates contain lead and silver in quantities ranging from 3 to 7 pr cent and 3 to 7 ounces, respectively, The lead and silver in the zinc concentrate is a total loss, as well as an expense; on a bases of 35 to 50 tons per day the loss becomes serious. The following tests were made with the object of recovering this lead and silver --pages 1-2
