Simulations of the last 500 yr carried out using the Third Hadley Centre Coupled Ocean–Atmosphere GCM (HadCM3) with anthropogenic and natural (solar and volcanic) forcings have been analyzed. Globalmean surface temperature change during the twentieth century is well reproduced. Simulated contributions to global-mean sea level rise during recent decades due to thermal expansion (the largest term...
This study shows that annual output data of the G7 countries in the twentieth century are better characterized as transitory deviations from a (shifting) growth trend than as integrated processes. Furthermore, I find no two countries share common business cycles. JEL classification: C22, E32, 057
The science of vaccinology was created in the late 18th and 19th centuries by "giants" of the time including Jenner, Pasteur, Koch, von Behring, Ehrlich and Lister. Relatively little technologic advance was made in the period leading to World War II except for yellow fever and influenza vaccines. Support for war efforts fueled developments which led to the modern era of vaccines of 1950 onwards...
All gauge theories need “something fixed” even as “something changes.” Underlying the implementation of these ideas all major physical theories make indispensable use of an elaborately designed spacetime model as the “something fixed,” i.e., absolute. This model must provide at least the following sequence of structures: point set, topological space, smooth manifold, geometric manifold, base fo...
This paper aims at explaining medium-term fertility variations in twentieth century Sweden by relating the total fertility rate to macro-level economic change and gender-specific changes in economic factors relevant to women’s childbearing behaviour. Economic theory is combined with a structural analytical approach in the multivariate time series analysis of the determinants of fertility. A mod...
Even today, leprosy is a relatively frequently occurring disease, especially in tropical regions of the world. From the eleventh to thirteenth century, leprosy pandemics affected Europe, including Croatia. Probably as a consequence of such history, one can still find endemic foci of leprosy in present-day Croatia. The aim of this study was to analyse all cases of leprosy registered in Croatia d...
J Bone Joint Surg [Br] 2007;89-B:1234-8. Received 1 February 2007; Accepted 24 April 2007 We have reviewed the data from our regional Bone Tumour Registry on patients with osteosarcoma diagnosed between 1933 and 2004 in order to investigate the relationship between survival and changes in treatment. There were 184 patients with non-metastatic appendicular osteosarcoma diagnosed at the age of 18...
As man is now changing the composition of the atmosphere at a rate which must be very exceptional on the geological time scale, it is natural to seek for the probable effects of such a change. From the best laboratory observations it appears that the principal result of increasing atmospheric carbon dioxide would be a gradual increase in the mean temperature of the colder regions of the earth. ...
While extended research into the Matthean Community is a relatively recent phenomenon in NT scholarship, most twentieth-century scholars working on the Gospel of Matthew have had either an explicit or implicit understanding of the Matthean Community against which they interpret the Gospel. This might be characterized as their understanding of the historical matrix out of which the Gospel arose,...
INTRODUCTION Singapore was substantially affected by three 20th Century pandemics. This study describes the course of the pandemics, and the preventive measures adopted. MATERIALS AND METHODS We reviewed and researched a wide range of material including peer-reviewed journal articles, Ministry of Health reports, Straits Settlements reports and newspaper articles. Monthly mortality data were o...
