Guidelines for developing agricultural information portals in the Southern African Development Community Region (SADC)

The Internet and the Web have become a source of agricultural information for many people, including researchers working in agricultural research organizations. According to Besemer, Addison and Ferguson (2003:2), the Web has changed the information landscape in the field of agriculture and natural resources. The relatively small investment required to set up a Web site enables a great many institutions to become instant information providers

Regulating the Multistate Practice of Law

This article will present some conclusions on theoretical grounds about the existing rules and the public protection rationale. There will be some discussion about the application of these rules to various multistate practice situations. Finally, the article will suggest directions for future empirical research in this area

The chemistry of substances and the philosophy of mass terms

In this paper I will contrast scientific knowledge about chemical substances uch as water with the recent philosophical discussion about natural kinds stimulated by lectures and publications of Kripke, Putnam, and others. 1 My conclusion will be that in order to define o

Minimally Invasive Mapping Guided Surgical Treatment of Atrial Fibrillation. Utopia or Near Future?

Isolation of the pulmonary veins has been used as surgical treatment for atrial fibrillation (AF) from the early 90s, as it was incorporated in the Maze procedure. With the evidence that triggers form this area can induce AF, the Maze III procedure has been adapted and modified towards a single lesion around the pulmonary veins for the treatment of paroxysmal and chronic AF in some centers. New ablation techniques with a diversity of energy sources further paved the way for less invasive procedures. Minimal invasive techniques to prevent major surgery may potentially make the treatment available for a patient population that do not have to undergo cardiac surgery for other reasons. Besides these technical developments, high density mapping can be used to identify the AF substrate in the individual patient and optimization of the treatment by local substrate guided ablation. This review aims to summarize the robotic and thoracoscopic techniques to isolate the pulmonary veins. Furthermore, it is discussed why pulmonary veins isolation may be effective in patients with chronic AF, and whether there is a role for mapping guided minimal invasive surgical treatment of AF in the near future

Treatment of Congenital and Acquired Undescended Testes

Undescended testis (UDT) is one of the most frequent urogenital abnormalities, and can be of congenital or acquired origin. The problem with most literature is that since acquired UDT was only recently accepted as a distinct entity, it does not discriminate between congenital and acquired UDT. For congenital UDT much is known on the aetiology, natural course, and treatment, however, these matters are less clear for acquired UDT
