The importance of the study of bovine central nervous diseases has increased worldwide since the appearance of the bovine spongiform encephalopathy (BSE), in the middle of the decade of 1980. The recognition of a new variant of the Creutzfeldt Jacob (human disease related to the BSE) has enhanced the economy and public health importance in the world. Due to this fact, international sanitary aut...

The annual survival rates and incidence of cerebral haemorrhage in 2618 preterm infants of 34 weeks' gestation or less were examined in one referral centre over a 10 year period from January 1980 to December 1989. Survival was independently related to weight, gestation, sex, and inborn delivery. When these variables had been taken into account, survival was 56% greater at the end of the decade ...

The roles of the cell membrane as both a permeability barrier to foreign substances and as a selective filter which admits nutrient molecules have been recognized as fundamentally important to animal physiology since the first decade of this century. It was not until the 1950's, however, that microbiologists recognized that bacteria possess membrane transport systems, distinct from their metabo...

BACKGROUND We analysed Australian general practice (GP) publications in PubMed from 1980 to 2007 to determine journals, authors, publication types, national health priority areas (NHPA) and compared the results with those from three specialties (public health, cardiology and medical informatics) and two countries (the UK and New Zealand). METHOD Australian GP publications were downloaded in M...

Prior to 1980, the only method to treat cardiac arrhythmias besides anti-arrhythmic drug therapy was open-heart surgery, that involved either dissecting or freezing the arrhythmic focus with a hand-held metal probe. Soon thereafter, early reports of percutaneously performed cardiac ablation were published that marked the beginning of a new era in the field of cardiac electrophysiology (EP). As ...

I investigate the role that matching frictions play in the Puerto Rican labor market. The search-theoretical models of the labor market which were developed in the 1980’s led to an explosion of empirical work in the search for evidence of the mechanisms that supported the theory. This paper seeks to measure the degree to which the Puerto Rican labor market is afflicted by congestion externaliti...

This paper combines the GCC and Convention Theory frameworks to compare the value-chains for agro-commodities before and after the decade 1980-90. Crudely, this period was a watershed between producer-driven and buyer-driven forms of organisation. Subsequently, two types of buyer-driven chain have become differentiated: one with low entry barriers that is experiencing downgrading, and one with ...

The late incorporation of Spain into the international circuit for publication results scientific research in Communication has not proved to be an obstacle reaching a level similar this discipline recently. However, development is still subject some obstacles. In study, we carried out co-word and cocitation analyses intellectual thematic structure articles published by researchers affiliated w...

Inflation dynamics in Turkey have been notoriously volatile for several decades. Starting the 1970 decade, inflation rates frequently reached three digit levels, remained high until 2000 and decreased to relatively low levels after 2001 as a consequence of series reforms. Considering alternating behavior Turkey, purpose this work is utilize different specifications, including time-varying trend...
