Albuquerque and Courtown are two small, uninhabited oceanic atolls, located in the southwestern Caribbean Sea, belonging to the San Andres and Providencia archipelago, Colombia. These atolls have a volcanic basement and are surrounded by deep water. Based on photo-interpretation of geomorphological and ecological features as well as on data collected during field work, the gross morphology, mar...

Trypanosoma cruzi, the hemoflagellate parasite and cause of Chagas disease in Latin America, is carried by Triatomine vectors, principally Triatoma dimidiata and Rhodnius prolixus in Central America. To assist control efforts and to understand the epidemiology of the disease in Guatemala, the population genetics of T. dimidiata was analyzed among three houses within a village and two adjacent v...

Detailed description of the geology, topography and terraces of the Danube Bend was presented in Chapter 3. “Traditional” terrace ages concerning this area were derived from “relevant” data of the neighbouring valley sections, as lack of datable material prevented the Danube Bend terraces from setting up a more reliable chronological frame. Application of a new dating method was necessary to qu...

In phylogenomic analysis the collection of trees with identical score (maximum likelihood or parsimony score) may hamper tree search algorithms. Such collections are coined phylogenetic terraces. For sparse supermatrices with a lot of missing data, the number of terraces and the number of trees on the terraces can be very large. If terraces are not taken into account, a lot of computation time ...

BACKGROUND AND AIM: An important goal of periodontal plastic surgery is the creation of attached gingiva around the teeth. In this study, the aims were to culture gingival fibroblasts in a biodegradable scaffold and measure the width of attached gingiva after the clinical procedure.METHODS: This study was carried out on 4 patients (8 sites), with inadequate attached gingiva next to at least two...

2 Abstract There has been a growing literature in both the US (for example Haurin and Brasington 1996, and Black 1999) and the UK (for example Gibbons & Machin, 2001), which estimates the way in which school quality is capitalised into house prices. In earlier work the present authors (Cheshire & Sheppard 1995; 1999) estimated a hedonic model for the housing markets of Darlington, Nottingham an...
