Ageing and Brugada syndrome: considerations and recommendations
Pieter G Postem,Hanno L Tan,Arthur AM Wilde,<br>Pieter G. Postem,Hanno L Tan,Arthur AM Wilde
老年心脏病学杂志(英文版) , 2013,
Abstract: Brugada syndrome is an inherited disease associated with an increased risk of lethal ventricular arrhythmias. Such arrhythmias stem from innate disruptions in cardiac electrophysiology. Typically, such arrhythmias occur in the third or fourth decade of life. However, Brugada syndrome may also affect geriatric patients. In this paper, we focus on the ageing patient with Brugada syndrome, and specifically, on the interaction between Brugada syndrome and the more usually acquired clinical problems that may occur with increasing age, such as the use of cardiovascular and non-cardiovascular drugs, or the need for surgery. Such common conditions may also disrupt cardiac electrophysiology, thereby conferring added risk for Brugada syndrome patients. We present some considerations and recommendations that may serve as guidance to address these complexities.
Injury rates in adult elite judoka
G James,W Pieter
Biology of Sport , 2003,
Abstract: The aim of the present study was to assess the injuries in British judo athletes (judoka) sustained during competition. Subjects were male (n=70) and female (n=46) elite judoka participating in a national judo tournament in the United Kingdom. Injury data were collected with simple check-off forms that describe the athlete, type, location and mechanism of injury. The Mann-Whitney U test was used to determine the difference in total injury rate between males and females. The Kruskal-Wallis test was used to determine the differences in injury rates between body regions. The men recorded a higher injury rate (48.54/1000 athlete-exposures) than the women (34.25/1000 athlete-exposures) (P<0.001). The major injury type was the strain (4.85/1000 athlete-exposures) in the men. The body part most often injured in the women was the elbow (13.70/1000 athlete-exposures). The major injury mechanisms in the men were delivering a throw and impact with surface (14.56/1000 athlete-exposures each). The time-loss injury rate for the men was 4.85/1000 athlete-exposures and 13.70/1000 athlete-exposures for the women. The injury rates in this sample compare favorably to those reported by others for other martial arts.

Cosmic-Ray Rejection by Laplacian Edge Detection
Pieter G. van Dokkum
Physics , 2001, DOI: 10.1086/323894
Abstract: Conventional algorithms for rejecting cosmic-rays in single CCD exposures rely on the contrast between cosmic-rays and their surroundings, and may produce erroneous results if the Point Spread Function (PSF) is smaller than the largest cosmic-rays. This paper describes a robust algorithm for cosmic-ray rejection, based on a variation of Laplacian edge detection. The algorithm identifies cosmic-rays of arbitrary shapes and sizes by the sharpness of their edges, and reliably discriminates between poorly sampled point sources and cosmic-rays. Examples of its performance are given for spectroscopic and imaging data, including HST WFPC2 images.
Formation and Evolution of Galaxies in Clusters
Pieter G. van Dokkum
Physics , 2001,
Abstract: Elliptical and S0 galaxies dominate the galaxy population in nearby rich clusters such as Coma. Studies of the evolution of the colors, M/L ratios, and line indices of early-type galaxies indicate that they have been a highly homogeneous, slowly evolving population over the last ~65% of the age of the Universe. On the other hand, recent evidence suggests that many early-type galaxies in clusters have been transformed from spiral galaxies since z~1. Arguably the most spectacular evidence for such transformations is the incidence of red merger systems in several high redshift clusters. Due to this morphological evolution the sample of early-type galaxies at high redshift is only a subsample of the sample of early-type galaxies at low redshift. This ``progenitor bias'' results in an overestimate of the mean formation redshift if simple models without morphological transformations are used. Models which incorporate morphological evolution explicitly can bring the homogeneity, slow evolution, and morphological transformations into agreement. The modeling shows that the corrected mean formation redshift of the stars in early-type galaxies may be as low as z~2 in a Lambda dominated Universe.

Reformed spirituality in action: The diary of A.D. Luckhoff as praxis
Pieter G.R. de Villiers
HTS Theological Studies/Teologiese Studies , 2011, DOI: 10.4102/hts.v67i3.1109
Abstract: This article discusses the praxis of Reformed Spirituality by investigating the diary of Reverend A.D. Luckhoff which he wrote during the Anglo-Boer War as chaplain in the infamous Bethulie concentration camp. The article locates Luckhoff and his diary in the context of Reformed Spirituality and in the study of Spirituality with special attention to their transformative actions on behalf of others and how this, in turn, affected his Spirituality. It points out the diary’s significance before it analyses the nature of Luckhoff’s Reformed Spirituality as it is evident in his pastoral activities and work ethic, his struggle for justice and dignity, and, finally, his political approach in a difficult situation. In conclusion some remarks are made about the nature of Luckhoff’s Reformed Spirituality. How to cite this article: De Villiers, P.G.R., 2011, ‘Reformed spirituality in action: The diary of A.D.

Hermeneutiese perspektiewe op geweld in die Nuwe Testament
Pieter G.R. de Villiers
HTS Theological Studies/Teologiese Studies , 2009, DOI: 10.4102/hts.v64i4.89
Abstract: Hermeneutical perspectives on violence in the New Testament This article discusses hermeneutical perspectives on violence in the New Testament as they appear in articles in this publication and in New Testament Studies in general. It contrasts the traditional perspective on the New Testament as book of peace with the growing insight in its violent nature. It is followed by a discussion of the multi-faceted nature of both notions of peace and violence and the various forms in which they are expressed. After an analysis of the relationship between violence and its alternatives, the various forms of violence are outlined in terms of their relationship to their experiential realities. This is followed by remarks about an adequate methodology for the study of violence, the way in which violence is countered in the New Testament texts and, finally, three possible explanations for the nature of violence.
The future existence of the believers according to 2 Thessalonians
Pieter G.R. de Villiers
HTS Theological Studies/Teologiese Studies , 2011, DOI: 10.4102/hts.v67i1.912
Abstract: This article investigated the presentation of the future existence of the believers in Paul’s second letter to the Thessalonians. It analysed how the eschatological language of this letter reflects a situation in Thessalonica which has grown worse since the writing of 1 Thessalonians. It went on to explain to readers how this situation is handled by reflecting on it in terms of a divine plan and by portraying a future in which their suffering will come to an end. A close reading of some passages in 2 Thessalonians which speak of the dispensation which will follow on the glorious return of Christ at the end were presented during the course of this article. It investigated Christ’s glorification at his return and delineated the way in which this return affects and determines the existence of those who accepted Paul’s proclamation of the gospel. The future glory of the Lord is revealed, experienced and shared by believers in a mystical manner. The article ended with a brief discussion on the traditions which determined this perspective, the context in which the eschatological portrait must be understood and how the portrait of the future serves to support the community of saints in their time of suffering.

Die kerk en sy mag in Openbaring 11

HTS Theological Studies/Teologiese Studies , 2012, DOI: 10.4102/hts.v68i1.1176
Abstract: The church and power in Revelation 11. The article discusses the notion of power in the episode of the two witnesses in Revelation 11:4–6 as a point of departure for a reflection on power in early Christian documents. It also aims to determine the meaning of power in terms of a close reading of a specific text so that discussions about its nature and about power in Biblical texts can be rooted in firm evidence. This evidence should then, at later stages be further developed with the aid of theoretical models and insights about power. In a first section power in Revelation 11:4 6 is described in terms of the identity and task of the witnesses and in terms of its divine origins, followed in a second part by reflection on the direct references to their power. Special attention is given to some seminal issues about power, namely, its relationship with truth and prophecy, its divine origins, the misuse of power, violence as a response to evil and, finally, its role in the Book of Revelation and Early Christianity.
