Automatic control of liquid cooling garment by cutaneous and external auditory meatus temperatures

An automatic control apparatus for a liquid cooling garment is described that is responsive to actual physiological needs during work and rest periods of a man clothed in the liquid cooling garment. Four skin temperature readings and a reading taken at the external portion of the auditory meatus are added and used in the control signal for a temperature control valve regulating inlet water temperature for the liquid cooling garment. The control apparatus comprises electronic circuits to which the temperatures are applied as control signals and an electro-pneumatic transducer attached to the control valve

If only it were true: the problem with the four conditionals

The traditional division of conditionals into four main types (zero, first, second, and third) has long been called into question. Unfortunately, the awareness that this description does not reflect conditional patterns in actual usage has not generally been reflected in EFL coursebooks. This article re-examines the arguments for a description of conditional patterns which reflects actual usage and uses corpus data to demonstrate the kind of patterns in frequent use. It then suggests two teaching approaches that may help teachers to tackle a variety of conditional patterns in the classroom

Who cares for the caregivers? : A comparative study of residential and day care teams working with children

The practice research question is first analysed from an historical and comparative perspective, using a grounded theory of enquiry to outline the perimeter of a distinctive field of study - group care. Twelve structural features of service design are identified and then used to locate the principal patterns of group care service - institutional care, residential group living and day care - within the social policy ideal of a continuum of care for children and families. The occupational focus of group care is then analysed to establish the theoretical relationship between quality of working life for personnel and the production of welfare services. Team functioning and staff experiences of life outside work are identified-as central concerns in the evaluation of service production capability in teams. Basic assumptions about teamwork in the practice domain of group care are evaluated, to establish the theoretical and methodological premises upon which an assessment of 8 ideal types of team functioning can be made. This action research paradigm is evaluated with respect to empirical findings obtained from a comparative sample of 63 different teams, working for 13 separate agencies in Scotland, England, Canada and the United States between 1977 and 1982. An illuminative case study of group care practice in one agency is also presented to highlight the relationship between resident group characteristics and patterns of team functioning for workers in group homes, institutional living units and secure units. Eight quality of working life hypotheses are evaluated through the use of a 'continuous comparative analysis of the data and non-linear statistics. Implications for practice are summarised for group care workers, managers, educators and policy makers

Control of a liquid cooling garment for extravehicular astronauts by cutaneous and external auditory meatus temperatures

Automatic temperature control for liquid cooling garments used during astronaut extravehicular activity with external auditory meatus, and skin temperature as input signal

The 3-dimensional Fourier grid Hamiltonian method

A method to compute the bound state eigenvalues and eigenfunctions of a Schr\"{o}dinger equation or a spinless Salpeter equation with central interaction is presented. This method is the generalization to the three-dimensional case of the Fourier grid Hamiltonian method for one-dimensional Schr\"{o}dinger equation. It requires only the evaluation of the potential at equally spaced grid points and yields the radial part of the eigenfunctions at the same grid points. It can be easily extended to the case of coupled channel equations and to the case of non-local interactions.Comment: 13 pages, 1 figure. RevTeX file. To appear in J. Comput. Phy

A semiclassical model of light mesons

The dominantly orbital state description is applied to the study of light mesons. The effective Hamiltonian is characterized by a relativistic kinematics supplemented by the usual funnel potential with a mixed scalar and vector confinement. The influence of two different finite quark masses and potential parameters on Regge and vibrational trajectories is discussed.Comment: 1 figur

Spacings of Quarkonium Levels with the Same Principal Quantum Number

The spacings between bound-state levels of the Schr\"odinger equation with the same principal quantum number $N$ but orbital angular momenta $\ell$ differing by unity are found to be nearly equal for a wide range of power potentials $V = \lambda r^\nu$, with $E_{N \ell} \approx F(\nu, N) - G(\nu,N) \ell$. Semiclassical approximations are in accord with this behavior. The result is applied to estimates of masses for quarkonium levels which have not yet been observed, including the 2P $c \bar c$ states and the 1D $b \bar b$ states.Comment: 20 pages, latex, 3 uuencoded figures submitted separately (process using psfig.sty

The Stokes-Einstein Relation in Supercooled Aqueous Solutions of Glycerol

The diffusion of glycerol molecules decreases with decreasing temperature as its viscosity increases in a manner simply described by the Stokes-Einstein(SE) relation. Approaching the glass transition, this relation breaks down as it does with a number of other pure liquid glass formers. We have measured the diffusion coefficient for binary mixtures of glycerol and water and find that the Stokes-Einstein relation is restored with increasing water concentration. Our comparison with theory suggests that addition of water postpones the formation of frustration domainsComment: 4 Pages and 3 Figure
