SUMMARY With the development of coronary care units in the 1960s, attitudes toward sudden cardiac death (SCD) began to change as physicians learned that cardiac arrest was reversible. The problem of SCD has two aspects an acute, precipitating factor and a chronic predisposition to electrical instability of the myocardium. Resolution of the problem requires identification and protection of the p...

Outlays for health care in the Nation reached $192.4 billion in calendar year 1978--13 percent higher than in 1977, according to preliminary figures compiled by the Health Care Financing Administration. This estimate represented $863 per person in the United States and was equal to 9.1 percent of the GNP. This latest report in the annual series representing national health expenditures provides...

This paper investigates intonational variation in Liverpool English, a dialect of British English that is recognised as having a number of distinctive phonetic characteristics [15, 16]. One previously reported aspect of Liverpool intonation is the presence of rising contours in declaratives as part of the traditional dialect [7]. Here we present a phonological Autosegmental Metrical analysis [9...

A number of studies show that premarital cohabitation is associated with an increased risk of subsequent marital dissolution. Some argue that this is a consequence of selection effects and that once these are controlled for premarital cohabitation has no effect on dissolution. We examine the effect of premarital cohabitation on subsequent marital dissolution by using rich retrospective life-his...

2014 The present paper discusses an experiment, using a Middleton sputter ion source, where a sensitive search was made for 14Nions in the presence of an intense carbon beam. It was found that negative nitrogen ions, capable of withstanding acceleration fields of 1.5 MV/m, were not produced in detectable intensities. The paper also points out some design requirements of tandem facilities that m...

During plant epidermal development, many cell types are generated fromprotodermal cells, a process requiringcomplex co-ordinationof cell division, growth, endoreduplication and the acquisition of differentiated cellular morphologies. Herewe show that theArabidopsis phytocalpain DEFECTIVE KERNEL 1 (DEK1) promotes the differentiated epidermal state. Plants with reduced DEK1 activity produce cotyl...
