Technique for stripping Teflon insulated wire
Cryogenic stripping of Teflon insulated wire leaves no residue and produces no physical damage. After the wire is immersed in liquid nitrogen, bent slightly, and returned to room temperature, the Teflon is removed by fingernails or flat-nosed pliers
Method and apparatus for cryogenic wire stripping Patent
Method and apparatus for removing plastic insulation from wire using cryogenic equipmen
Pressure distributions on three different cruciform aft-control surfaces of a wingless missile at Mach 1.60, 2.36, and 3.70. Volume 2: Clipped delta tail
Pressure coefficients were obtained in the Langley Unitary Plan wind tunnel for a wingless missile with a clipped delta tail. The angle of attack was varied from -4 deg to 20 deg, model roll angle was varied from 0 deg to 90 deg in 22.5 deg increments, and tail deflections were 0 deg to - 15 deg. The pressures were measured on two adjacent tail surfaces using 91 pressure orifices per tail surface. Results are presented in plotted and tabular form

The results of pressure distribution tests are presented without analysis. The test Reynolds number used was 6.6. x 10 to the 6th power per meter
Vapor-screen technique for flow visualization in the Langley Unitary Plan Wind Tunnel
The vapor-screen technique for flow visualization, as developed for the Langley Unitary Plan Wind Tunnel, is described with evaluations of light sources and photographic equipment. Test parameters including dew point, pressure, and temperature were varied to determine optimum conditions for obtaining high-quality vapor-screen photographs. The investigation was conducted in the supersonic speed range for Mach numbers from 1.47 to 4.63 at model angles of attack up to 35 deg. Vapor-screen photographs illustrating various flow patterns are presented for several missile and aircraft configurations. Examples of vapor-screen results that have contributed to the understanding of complex flow fields and provided a basis for the development of theoretical codes are presented with reference to other research
Theory and simulation of spectral line broadening by exoplanetary atmospheric haze
Atmospheric haze is the leading candidate for the flattening of expolanetary
spectra, as it's also an important source of opacity in the atmospheres of
solar system planets, satellites, and comets. Exoplanetary transmission
spectra, which carry information about how the planetary atmospheres become
opaque to stellar light in transit, show broad featureless absorption in the
region of wavelengths corresponding to spectral lines of sodium, potassium and
water. We develop a detailed atomistic model, describing interactions of atomic
or molecular radiators with dust and atmospheric haze particulates. This model
incorporates a realistic structure of haze particulates from small nano-size
seed particles up to sub-micron irregularly shaped aggregates, accounting for
both pairwise collisions between the radiator and haze perturbers, and
quasi-static mean field shift of levels in haze environments. This formalism
can explain large flattening of absorption and emission spectra in haze
atmospheres and shows how the radiator - haze particle interaction affects the
absorption spectral shape in the wings of spectral lines and near their
centers. The theory can account for nearly all realistic structure, size and
chemical composition of haze particulates and predict their influence on
absorption and emission spectra in hazy environments. We illustrate the utility
of the method by computing shift and broadening of the emission spectra of the
sodium D line in an argon haze. The simplicity, elegance and generality of the
proposed model should make it amenable to a broad community of users in
astrophysics and chemistry.Comment: 16 pages, 4 figures, submitted to MNRA
Substance Abuse, Families, and Unified Family Courts: The Creation of a Caring Justice System
This article proposes an approach to family law decision-making tailored to assist families plagued by substance abuse. Substance abuse is linked to social, health, and economic problems facing Americans today and is a factor for a substantial number of family law litigants. By failing to address substance abuse issues, the family repeatedly may need to seek court intervention. The unified family court model is the concept of a single court that coordinates the work of independent agencies and tribunals, each with some limited role in resolving the problems incident to a family\u27s legal matters. Professor Babb has created an interdisciplinary framework for a unified family court, based on therapeutic jurisprudence and the ecology of human development, to help judges and other court professionals consider the many influences on human behavior and family life, thereby empowering the system to offer more pragmatic and effective solutions to contemporary family legal issues. The authors use the Family Division of the Circuit Court for Baltimore City, Maryland, as a case study to illustrate the proposed model. The authors describe the court structure, role of court personnel, and court services. Among the court services are substance abuse resources for litigants. If a judge and/or other court personnel are concerned about substance abuse, they may refer the litigant to a court clinical social worker, who evaluates litigants for substance abuse, prepares a court report, and refers family members to treatment as necessary. For this system to work, expertise in addiction and substance abuse is imperative. The authors conclude that all family justice systems must make a commitment to address substance abuse issues, both by understanding how these issues affect family law cases and by developing policies and procedures to effectively respond to the problem
