Corals, fishermen and tourists

Two major anthropogenic activities that disturb coral reefs are fishing and tourism, even though coral reefs are important for both fishing and tourism. Already more than 60 per cent of all reefs worldwide are endangered. The use of explosives and poison by small-scale fishers, to supply the market for live fish for aquariums and for human consumption, cause irreversible damages to reefs. Similarly, rapid and unmanaged coastal development for marine tourism negatively affects coral reefs in many ways. Though marine parks and marine protected areas are being promoted all over the world, developing countries need assistance in establishing and assessing such reserves and for taking appropriate actions for rehabilitation of reefs. These can be accomplished through partnership projects

On the way to management of west Sumatra's coastal ecosystem

Various impacts on the coast of the Indonesian province of West Sumatra are presented together with activities and achievements to address them, e.g. public awareness, public relations and capacity building, including the establishment of a marine protected area

Ueberlegungen zu ISO 10303 - Datenaustauschformat oder Modellierungsbasis?

Im vorliegenden Artikel werden Moeglichkeiten zum Einsatz von STEP als Basis einer systemneutralen und rein anwendungsbezogenen Produktdatenmodellierung vorgestellt. Dabei wird auf einen CA-systemneutralen Ansatz der Betriebsdatenhaltung reflektiert, fuer welchen als praedestinierte Systeme objektorientierte Datenbanken zum Einsatz kommen sollen. Auf dem Wege der produktstruktur- basierten Modellierung von Daten kann der Anwender produktspezifische Anforderungen beruecksichtigen. Ausserdem kann die Auswahl der einzusetzenden CA-Systeme nach rein funktional-wirtschaftlichen Kriterien erfolgen

Correlation between capillary oxygen saturation and small intestinal wall thickness in the equine colic patient

The surgical evaluation of haemorrhagic infarcted intestine and the decision for or against bowel resection require a lot of experience and are subjective. The aim of this prospective, clinical study was to examine the correlation between oxygen saturation and small intestinal wall (IW) thickness, using two objective methods. In 22 colicky horses, the blood flow, oxygen saturation and relative amount of haemoglobin were measured intraoperatively via laser Doppler and white light spectroscopy (O2C, oxygen to see, LEA Medizintechnik) at six measuring points (MPs) in small and large intestines. Furthermore, the IW thickness was measured ultrasonographically. Nine of 22 horses had an increased small IW thickness greater than 4?mm (Freeman 2002, Scharner and others 2002, le Jeune and Whitcomb 2014) at measuring point 1 (MP1) (strangulated segment), four horses had a thickened bowel wall at measuring point 3 (MP3) (poststenotic) and one at measuring point 2 (MP2). The oxygen saturation was 0 at MP1 in six horses, at MP3 in two horses and at MP2 (prestenotic) in one. Oxygen saturation and small IW thickness were independent of each other at MP1 and MP2. At MP3, the two parameters were negatively correlated. In summary, it is not possible to draw conclusions about oxygen saturation based on IW thickness

Retracing labial-velar consonants in Mbum (Adamawa): Between genetic transmission and language contact

Labial-velar consonants, which are typologically rather rare in the languages of the world, have been used for both genealogical and areal classification purposes. The claim that their occurrence mainly signals areal contact (e.g. Güldemann 2008), has been criticized by scholars (cf. Cahill 2017, Childs 2017) who point out a possible genealogical development in multiple language families of Africa. In this paper, we analyse contemporary and historical data on Mbum varieties from the Adamawa plateau in Cameroon and closely related languages of the Kebi-Benue family to approach the question whether labial-velars are transmitted merely through contact in these languages or warrant a genealogical explanation. The bottom-up approach leads to an interpretation of the current distribution of labial-velars that has both elements in it: There are arguments for reconstructing labial-velars for the Proto-Kebi-Benue level, but certain specifics of their geographical distribution also hint at a contact explanation.Labial-velar consonants, which are typologically rather rare in the languages of the world, have been used for both genealogical and areal classification purposes.
