    To describe the behaviour of watercourses, numerous parameters should be considered, such as water flow, depth/water level, velocity, and the amount of deposit in a waterbed. In addition, many other parameters should be analysed to understand the mechanism of specific watercourses. The most typical parameters are those associated with water quality, such as water temperature, and pH value, and temperature, as well as various climate parameters, such as precipitation, evaporation, and insolation, which are visualised in the form of a time series. The measurement frequency can differ for each parameter. Depending on the number of available measurements, hourly, daily, monthly, and yearly data can be obtained, which can then be used to form a time series. Many well-established and applicable procedures and models for time-series analyses exist, including the rescaled adjusted partial sums method (RAPS). This method is devised to detect possible irregularities and/or fluctuations within the original time series, which cannot be achieved using typical time[1]series analysis methods. This paper presents a comprehensive review of the application of the RAPS method in hydrology, where the advantages and disadvantages of the method are discussed

    Fatal impalement with transfixion of the neck in a road traffic accident

    No full text
    The authors describe a singular case of fatal impalement due to penetration of a metal tube at the level of the neck in a victim of a road traffic accident. The man was traveling in the passenger seat ("death seat") of a car that hit the parapet of a bridge head on; death was attributed to hemorrhagic shock, which was brought on virtually instantly at the moment of impact

    Synthesis of N,N,N’,N’-tetraalkylbenzidines through oxidative coupling of N,N-dialkylarylamines induced by SbCl5

    No full text
    The oxidative coupling to 4,4’-N,N,N’,N’-tetraalkylbenzidines is the main reaction observed during a study on the reactivity of N,N-dialkylanilines with SbCl5. A possible reaction mechanism is presented and discussed in comparison with the N,N-dialkylanilines oxidative coupling achieved with other Lewis acids
