Streams and rivers play an important role in the global carbon cycle. The origins of CO2 streams are often poorly constrained or neglected, which is especially true for originating from heterotrophic metabolism streambeds. We hypothesized that sediment movement will have a direct effect on stream metabolism, thus, aim this study was to quantify moving bedforms production sandy conducted flume e...

We have developed an effective analytical method to determine the concentration of paraquat in human plasma by high-performance liquid chromatography (HPLC), which can provide methodological support for diagnosis, therapy, and prognostic evaluation of acute poisoning related to paraquat. The plasma samples were deproteinized with 35% perchloric acid. Then the paraquat was extracted from the sam...

This article presents a critique of psychological, disciplinary, and cultural propensities to favor speed of thought and action over other considerations, a propensity which warrants the designation "cult of celerity. " Certain cultural manifestations of a cult of celerily are briefly discussed A number of areas of illustrative psychological inquiry are examined-heuristics, the satisficing prin...

Abstract Providing convenient APIs and notations for data parallelism which remain accessible programmers while still providing good performance has been a long-term goal of researchers as well language library designers. C++20 introduces ranges views, the composition operations on them using concise syntax, but efficient implementation these features is restricted to CPUs. We present Celerity ...

Rapid transients are particularly dangerous in industrial hydro-transport systems, where solid-liquid mixtures transported via long pressure pipelines. A mathematical description of such flow is difficult due to the complexity phenomena and difficulties determining parameters. The main aim study was examine influence simplified mixture density wave celerity on satisfactory reproduction characte...

Employing a linear shallow water equation (LSWE) model in the spherical coordinates, this paper investigates tsunami waves generated by atmospheric pressure shock due to explosion of submarine volcano Hunga Tonga–Hunga Ha'apai on 15 January 2022. Using selected 59 records Pacific Ocean, an empirical is first constructed. Applying and realistic bathymetric data LSWE model, generation propagation...

Here, recent developments in the key numerical approaches to water hammer modelling are summarized and critiqued. This paper summarizes one-dimensional using finite difference method (FDM), of characteristics (MOC), especially more volume (FVM). The discussion is briefly extended two-dimensional modelling, as well computational fluid dynamics (CFD) approaches. Finite methods particular note, si...
