A new dry biomedical electrode

Electronic circuitry contains new operational amplifier which incorporates monolithic super-gain transistors. Electrode does not provide voltage amplification; instead, it acts as current amplifier to make it possible to pick up electrical potentials from surface of highly resistant dry skin

Fear in childbirth: are the media responsible?

This is the second year that the Centre for Midwifery, Maternal and Perinatal Health convened a debate as part of the Festival of Learning at Bournemouth University (BU). The debate encourages members of the public and service users to get involved in our research and education and ensures that what we do at BU is relevant and current. Last year the team debated the pros and cons of allowing women free choice with regard to major medical interventions, such as caesarean section (Hundley et al. 2013). This year the focus was on the role of the media in childbirth. Social perceptions and beliefs about childbirth can increase women’s requests for interventions, such as caesarean section, with long-term health implications for mothers and babies. The debate was planned to explore the role of the mass media in shaping these beliefs and identify whether media portrayals are responsible for rising rates of intervention. Attendees were given the opportunity to voice their views and to vote for or against the motion. The motion for debate was: This house believes that: The media is responsible for creating fear in childbirth

Constitution-Making under UN Auspices: Fostering Dependency in Sovereign Lands by Vijayashri Sripati

This book is a groundbreaking study of United Nations Constitutional Assistance (UNCA), that is, constitution making in nominally sovereign states, carried out under the auspices of the United Nations (UN) in the guise of technical assistance. The book is of interest to scholars in various fields, from those engaged directly in the emerging field of international constitutional law to those with a general interest in globalization, peace building, and the international institutions that give structure to international governance

Degradation and reuse of radiative thermal protection system materials for the space shuttle

Three silicide coated columbium alloys and two cobalt alloys were subjected to identical simulated reentry profiling exposures in both static (controlled vacuum leak) and dynamic (hypersonic plasma shear) environments. Primary emphasis in the columbium alloy evaluation was on the Cb752 and C129Y alloys with a lesser amount on FS85. Commercial silicide coatings of the R512E and VH109 formulations were used. The coated specimens were intentionally defected to provide the types of coating flaws that are expected in service. Temperatures were profiled up to peak temperatures of either 2350 F or 2500 F for 15 minutes in each cycle

Microminiaturized, biopotential conditioning system (MBCS)

Multichannel, medical monitoring system allows almost complete freedom of movement for subject during monitoring periods. System comprises monitoring unit (biobelt), transmission line, and data acquisition unit. Belt, made of polybenzimidizole fabric, is wrapped around individual's waist and held in place by overlapping sections of Velcro closure material

Social inequalities in breast cancer mortality among French women: disappearing educational disparities from 1968 to 1996

We investigated the time trends in social inequalities in breast cancer mortality with an analysis by age at death and birth cohort using a representative 1% sample of the French population and four subcohorts (1968–1974, 1975–1981, 1982–1988 and 1990–1996). Causes of death were obtained by direct linkage with the French national death registry. Education was measured at the beginning of each period, and educational disparities in breast cancer mortality were studied among women aged 35–74 at the beginning of each period. In the 1970s, higher breast cancer mortality was found among higher educated women. This positive association progressively weakened and no association remained in the 1990s although it disappeared earlier among younger women. In an analysis by birth cohort, the same pattern was found among women born before 1925, whereas no association between education and mortality was observed among women born after 1925. Educational disparities in breast cancer mortality are currently changing and the previously observed positive gradient has disappeared. An important question is whether these relations are indirect, and due to changes in the prevalence of risk factors associated with education, but which we could not study

Trapping of Energetic Ions by Neutralization of a Polarized Beam

Recent experiments show that a positive ion beam with a density exceeding 10/sup 8/ ions/cm/sup 3/ will neutralize its space charge by trapping electrons within the beam. This trapping of electrons converts the ion beam to a neutral plasma suitable for injection and polarization experiments in a cross magnetic field. The ion energy used is about 500 volts. The beam moves readily across the magnetic field due to polarization of positive and negative charges. To create a hot plasma, it will be necessary to use higher energy ions, increase beam density, and retain neutralization by trapped electrons. (W.L.H.

On ordinal utility, cardinal utility, and random utility

Though the Random Utility Model (RUM) was conceived  entirely in terms of ordinal utility, the apparatus throughwhich it is widely practised exhibits properties of  cardinal utility.  The adoption of cardinal utility as a  working operation of ordinal is perfectly valid, provided  interpretations drawn from that operation remain faithful  to ordinal utility.  The paper considers whether the latterrequirement holds true for several measurements commonly  derived from RUM.  In particular it is found that  measurements of consumer surplus change may depart from  ordinal utility, and exploit the cardinality inherent in  the practical apparatus.
