Popular Abstract in English Global invasion of our precious watercourses by cyanobacteria poses great threat to human- and animal health by deteriorating water systems. In fact, this problem is not likely to be solved in the near future as cyanobacteria are associated with pollution of waterways. Consequently, water sources are subject to contamination by natural toxins produced by abundant growthCyanobacteria blooms are a water menace since they produce potent toxins that have been implicated in poisonings and deaths of humans and animals after consumption or contact with cyanotoxin-contaminated water. Of particular concern are cyanotoxins called microcystins, which are hepatotoxic cyclic peptides known to promote development of liver tumors in humans and animals. The high toxicity and in

Leonardo da Vinci Community Vocational Training Action Programme’s pilot project within Geographical Information Science (GIS), should be implemented over a three year period, 2002-2005. The main objectives of the project is to establish co-operation between European Universities and GIS user organisations and to develop modularised courses intended for Internet based learning, establish links of

Popular Abstract in Swedish Ultraljudundersökning av hjärtat (ekokardiografi) har under det senaste decenniet fått en alltmer framträdande roll i diagnostiken av hjärtsjukdomar och används ofta för att vägleda medicinska beslut inom hjärtsjukvården. Ekokardiografi är av central betydelse framförallt vid undersökning av vänsterkammarens pumpförmåga (systoliska funktion) och hjärtklaffarnas funktionTwo specific areas of development in echocardiography are assessment of left ventricular (LV) diastolic function and myocardial ischemia. This thesis describes echocardiographic methodology in these two areas. In the first study, two new echocardiographic methods, the early diastolic flow propagation velocity (Vp) and the early diastolic atrioventricular plane downward slope (EDS), were tested as

Most control systems involve the execution of periodic activities, which are automatically activated by the operating system at the specified rates. When the application consists of many concurrent tasks, each control activity may experience delay and jitter, which depend on several factors, including the scheduling algorithm running in the kernel, the overall workload, the task parameters, and th

This paper develops a very simple test for the null hypothesis of no cointegration in panel data. The test is general enough to allow for heteroskedastic and serially correlated errors, unit-specific time trends, cross-sectional dependence and unknown structural breaks in both the intercept and slope of the cointegrated regression, which may be located at different dates for different units. The l
