Technique for increasing yield of trifluoroni-trosomethane-tetrafluoro- ethylene copolymer

Polymerization technique using equimolar amounts of trifluoronitrosomethane and tetrafluoroethylene to increase yield of copolymer is described. Yields were increased by ninety percent and final product displayed better physical properties. Test equipment and chemical reactions for process are described

Development of conformal coating materials

New polymeric compositions appear useful as coatings on electronic circuitry operating in rigorous environments. Formulation of their compositions is based on nitrosofluorocarbon polymers having active cure sites

Seeking Freedom: A Child Finds Himself behind Bars

Language Disfluency and Diagnosis in the Deaf Inpatient Population

This study was designed to investigate the relationship between language dysfluency in the deaf inpatient population and the following variables: psychiatric diagnosis, risk of harm to self and others and psycho-social functioning admission scores on the Clinical Evaluation of Risk and Functioning Scale - Revised(CERF-R), and cognitive ability as measured by the Allen Cognitive Level Scale(ACL). The research found that 75% of deaf individuals fell into the non-fluent range of communication in ASL, their best language. Participants with severe language dysfluency received DSM-IV diagnoses concentrated in more severe forms of psychopathology, while individuals with fluent language skills received a broader range of diagnoses. Individuals with severe language dysfluency exhibited lower cognitive scores, overall lower functioning scores but not higher risk scores. The data suggest that future research is needed to develop a better understanding of language dysfluency, the distinction between language dysfluency and psychopathology, and of the behavioral patterns of deaf individuals who have faced a life-long history of severe language deprivation

Lessons Learned from 23 Years of a Deaf Psychiatric Inpatient Unit: Part 1

The author was the director or co-director of a specialty Deaf psychiatric inpatient unit for 17 of its 23 years. This program was established as a culturally affirmative mental health program. The author reflects back on what this has meant and how the unit staff struggled to create a program that was both culturally and clinically competent. In Part 1 of this two-part article, the lessons learned about some unique clinical challenges are discussed. These involved the challenges of working with ASL competent deaf persons and with deaf persons with severe language dysfluency in their best language, sign. The question of whether some of the deaf clients have a unique clinical syndrome involving severe language deprivation and an array of psychosocial deficits and behavioral problems is also discussed. Part II of the article discusses lessons learned about adaption of best practices in psychiatric rehabilitation for language and learning challenged deaf persons. In Part II, the author also reviews the lessons learned about staff and program development including the need to balance cultural and clinical competence and respond skillfully to Deaf/hearing cross- cultural conflicts

DES and Emotional Distress: \u3cem\u3ePayton v. Abbott Labs\u3c/em\u3e

In Payton v. Abbott Labs, the Massachusetts Supreme Judicial Court held that no cause of action exists for negligently inflicted emotional distress absent physical harm. The author analyzes Payton in relation to the historical development of mental and emotional distress in the law of torts. The author argues that the physical harm requirement is arbitrary and unreasonable and that it often precludes the litigation of serious claims

The cost and risk impacts of rerouting railroad shipments of hazardous materials

Cataloged from PDF version of article.Rail shipments of hazardous materials expose the population near the routes to the possibility of an accident resulting in a spill. Rail routes are determined by economic concerns such as route length and the revenue generated for the originating carrier. In this paper we consider an alternate routing strategy that takes accident risks into account. We employ a model to quantify rail transport risk and then use a weighted combination of cost and risk and generate alternate routes. In some cases the alternate routes achieve significantly lower risk values than the practical routes at a small incremental cost. While there are generally fewer rerouting alternatives for rail than for road transport, considering the possible consequences of a train derailment we argue that risk should be taken into account when selecting rail routes and that the cost–risk tradeoffs should be evaluated. © 2007 Elsevier Ltd.

Androgen-independent events in penile development in humans and animals.

The common view on penile development is that it is androgen-dependent, based first and foremost on the fact that the genital tubercle forms a penis in males and a clitoris in females. However, critical examination of the complex processes involved in human penile development reveals that many individual steps in development of the genital tubercle are common to both males and females, and thus can be interpreted as androgen-independent. For certain developmental events this conclusion is bolstered by observations in androgen-insensitive patients and androgen receptor mutant mice. Events in genital tubercle development that are common to human males and females include: formation of (a) the genital tubercle, (b) the urethral plate, (c) the urethral groove, (d) the glans, (e) the prepuce and (f) the corporal body. For humans 6 of 13 individual developmental steps in penile development were interpreted as androgen-independent. For mice 5 of 11 individual developmental steps were found to be androgen-independent, which were verified through analysis of androgen-insensitive mutants. Observations from development of external genitalia of other species (moles and spotted hyena) provide further examples of androgen-independent events in penile development. These observations support the counter-intuitive idea that penile development involves both androgen-independent and androgen-dependent processes
