Two-way digital driver/receiver uses one set of lines

Two-way /bilateral/ digital driver/receiver system using MOS circuits was designed for a multiprocess computer having several subsystems at relatively close locations. The system requires only a single set of communication lines between subsystems, thus achieving lower cost with increased reliability

Tissue macerating instrument

A surgical tissue macerating and removal tool is described which has a rotating rod with a cutting member at one end and which disposed in a tube which is then contained in an extension of the tool handle. A frusto-conical member extends into the extension at the cutter member end of the rotating rod with its small end engaging the tube. The portion of the frusto-conical member outside of the extension forms a tissue engaging member and may be cut-off at an angle to the axis of the rod to form a tissue engaging edge. Apertures are provided in the extension adjacent the frusto-concial member so that treatment fluid supplied in the annular space between the tube and the extension may flow to the operative site. An aperture is provided in the frustoconical member between the extension and the tube so that fluid may also flow into the tube where it mixes with macerated tissue being directed through an aperture in the tube to a passageway which may have suction applied to help remove macerated material

21st century social work: reducing re-offending - key practice skills

This literature review was commissioned by the Scottish Executive’s Social Work Services Inspectorate in order to support the work of the 21st Century Social Work Review Group. Discussions in relation to the future arrangements for criminal justice social work raised issues about which disciplines might best encompass the requisite skills for reducing re-offending in the community. Rather than starting with what is known or understood about the skills of those professionals currently involved in such interventions, this study sought to start with the research evidence on effective work with offenders to reduce re-offending and then work its way back to the skills required to promote this outcome

A Health Education Program In The Junior High School, Wichita Falls, Texas

It is the purpose of the investigator to set up a \u27 workable integrated health education program for the Washington\u27Junior High School, Wichita Falls, Texas. The Purpose of the Problem (1) To determine the physical needs of each boy and girl and to provide such instruction as will result in his highest physical efficiency. (2) To develop organic vigor, neuro-muscular strength, and skill, coordination, good posture, courage, confidence, sound judgment, will power, and self-control. (3) To learn and observe the fundamental laws of health. (4) To train pupils in the formation of ideals of right living that will guide them in the social and civic life of the community. (5) To develop a consciousness of the relation of maximum health to the acquisition of abilities in other phases of efficient living

Intraocular pressure reduction and regulation system

An intraocular pressure reduction and regulation system is described and data are presented covering performance in: (1) reducing intraocular pressure to a preselected value, (2) maintaining a set minimum intraocular pressure, and (3) reducing the dynamic increases in intraocular pressure resulting from external loads applied to the eye

Relational Identities: Reclaiming Ourselves through Recreating Each Other in Collaborative Conversations in Group Therapy Work

This project took place at an outpatient mental health setting, and offers new understandings in our pursuit for communal well-being. It documents the unique participation of group members in the co-creaction of new knowledge and better understanding of human relationships using a participatory action research methodology. The article explores how improvements can take place in the lives of people diagnosed as chronically mentally ill. It demonstrates how a postmodern, collaborative approach to group therapy impacted the ways in which persons diagnosed with serious and chronic mental illness recreated their identities, thereby affecting their ways of relating to others and to themselves. It examines the social and communal components of understanding human behavior, moving away from an intrapsychic and individualistic framework. Doing so allows us to expand our awareness and utilize our humanity in the treatment of people who have been diagnosed with mental illnesses. The role and power of collaboration are illustrated by considering the unique ways group members presented their ideas and behaved with one another. Possibilities for more sustainable ways of living together and sharing meaningful moments are considered. This article can serve as an invitation for how mental health professionals can also contribute to a culture of peace

Simultaneous dual-element analyses of refractory metals in naturally occurring matrices using resonance ionization of sputtered atoms

The combination of secondary neutral mass spectrometry (SNMS) and resonance ionization spectroscopy (RIS) has been shown to be a powerful tool for the detection of low levels of elemental impurities in solids. Drawbacks of the technique have been the laser-repetition-rate-limited, low duty cycle of the analysis and the fact that RIS schemes are limited to determinations of a single element. These problems have been addressed as part of an ongoing program to explore the usefulness of RIS/SNMS instruments for the analysis of naturally occurring samples. Efficient two-color, two-photon (1+1) resonance ionization schemes were identified for Mo and for four platinum-group elements (Ru, Os, Ir, and Re). Careful selection of the ionization schemes allowed Mo or Ru to be measured simultaneously with Re, Os, or Ir, using two tunable dye lasers and an XeCl excimer laser. Resonance frequencies could be switched easily under computer control, so that all five elements can be rapidly analyzed. In situ measurements of these elements in metal grains from five meteorites were conducted. From the analyses, estimates of the precision and the detection limit of the instrument were made. The trade-off between lower detection limits and rapid multielement RIS analyses is discussed

Local continuity laws on the phase space of Einstein equations with sources

Local continuity equations involving background fields and variantions of the fields, are obtained for a restricted class of solutions of the Einstein-Maxwell and Einstein-Weyl theories using a new approach based on the concept of the adjoint of a differential operator. Such covariant conservation laws are generated by means of decoupled equations and their adjoints in such a way that the corresponding covariantly conserved currents possess some gauge-invariant properties and are expressed in terms of Debye potentials. These continuity laws lead to both a covariant description of bilinear forms on the phase space and the existence of conserved quantities. Differences and similarities with other approaches and extensions of our results are discussed.Comment: LaTeX, 13 page
