Seismically induced soft-sediment deformation in crevasse-splay microdelta deposits (Middle Miocene, central Poland) – reply

Lilianna Chomiak, Piotr Maciaszek, Robert Wachocki, Marek Widera, more

Geological Quarterly > 2019 > Vol. 63, No. 2 > 429--433

We expected that our paper on the crevasse-splay microdelta (Chomiak et al., 2019) would arouse the interest of other researchers for at least two reasons. First, this is the first such palaeoform discovered and described within the Mid-Miocene lignite seam in Poland. Second, the microdelta siliciclastic deposits are strongly deformed both ductile and brittle. Therefore, we would like to thank Tom...

Seismically-induced soft-sediment deformation in crevasse-splay microdelta deposits (Middle Miocene, central Poland)

Liliana Chomiak, Piotr Maciaszek, Robert Wachocki, Marek Widera, more

Geological Quarterly > 2019 > Vol. 63, No. 1 > 162--177

Crevasse-splay microdelta deposits and their soft-sediment deformation structures (SSDS) are described from a tectonically active lignite-bearing area. These strongly deformed siliciclastic deposits, situated between two lignite benches, are typical of a crevasse-splay microdelta. They accumulated in the overbank zone of a Middle Miocene river system (backswamp area) where shallow ponds or lakes occasionally...

BMC Medical Genetics > 2018 > 19 > 1 > 1-7

Background Mutations of the SCN5A gene are reported in 2-4% of patients with dilated cardiomyopathy (DCM). In such cases, DCM is associated with different rhythm disturbances such as the multifocal ectopic Purkinje-related premature contractions and atrial fibrillation. Arrhythmia often occurs at a young age and is the first symptom of heart disease. Case presentation We present the case of 55-year...

Janusz Jurczak, Pawel Dydio, Pawel Stepniak, Tomasz Zielinski

Sensors and Actuators B: Chemical > 2016 > 237 > C > 621-627

We describe the synthesis and properties of bisamide derivatives of naphthalenedipyrrole, which represent a convenient platform for the construction of fluorescent anion sensors. As we show, the spectroscopic properties of such sensors can be fine-tuned through small modifications of the structure at the sensor periphery. The strong fluorescence of these compounds is perturbed through the binding...
