Current propagation type self-consistent leader-return stroke model

A current propagation type return stroke model which is consistent with the estimated distribution of the charge on the leader channel is described. The model takes into account the dispersion of the return stroke current along the return stroke channel. T ...

Aerosol optical absorption coefficients at seven wavelengths in 10 min resolution measured in the Swiss container during MOSAiC 2019/2020

Julia Schmale, Ivo Fabio Beck, Benjamin Jérémy Laurent Heutte, Lubna Dada

This dataset contains aerosol optical absorption coefficients at seven different wavelengths (babs(λ)), averaged to 10 min time resolution, measured during the year-long MOSAiC expedition from October 2019 to September 2020. The measurements were performed ...

A Current Propagation Type Return Stroke Model Consistent with the Leader Charge Distribution

Marcos Rubinstein, Farhad Rachidi-Haeri

We describe a current propagation type return stroke model which is consistent with the estimated distribution of the charge on the leader channel. The model takes into account the dispersion of the return stroke current along the return stroke channel. Th ...

Modified Transmission Line Model with a Current Attenuation Function Derived from the Lightning Radiation Field—MTLD Model

Marcos Rubinstein, Farhad Rachidi-Haeri

In return strokes, the parameters that can be measured are the channel base current and the return stroke speed. For this reason, many return stroke models have been developed with these two parameters, among others, as inputs. Here, we concentrate on the ...

Interactions Between Parallel Unevenly Heated Minichannels During Flow Boiling of R134A

Dolaana Khovalyg

Transient pressure drop of individual channels during flow boiling of R134a in four 0.54 mm square parallel minichannels was experimentally studied in this work. The design of the test section enabled the experimenter to control and to vary heat flux indep ...

Low density polyethylene (LDPE) passive samplers for the investigation of PCB point sources in rivers

Luiz Felippe De Alencastro, Nicolas Estoppey, Julien Omlin, Adrien Schopfer

This study aims to provide a passive sampling approach which can be routinely used to investigate polychlorinated biphenyl (PCB) sources in rivers. The approach consists of deploying low density polyeth- ylene (LDPE) strips downstream and upstream of poten ...

QSpike tools: a generic framework for parallel batch preprocessing of extracellular neuronal signals recorded by substrate nnicroelectrode arrays

Michele Giugliano, Eleni Vasilaki

Micro-Electrode Arrays (MEAs) have emerged as a mature technique to investigate brain (dys)functions in vivo and in in vitro animal models. Often referred to as "smart" Petri dishes, MEAs have demonstrated a great potential particularly for medium-throughp ...

Influence of diatoms on copepod reproduction. II. Uncorrelated effects of diatom-derived alpha,beta,gamma,delta-unsaturated aldehydes and polyunsaturated fatty acids on Calanus helgolandicus in the field

We set up a survey involving comprehensive chemical analyses of phytoplankton and the simultaneous monitoring of the reproductive response of Calanus helgolandicus. Hatching success and larvae development of C helgolandicus were monitored weekly with femal ...

On-column conductivity detection in capillary-chip electrophoresis

Hubert Girault

On-column conductivity detection in capillary-chip electrophoresis was achieved by actively coupling the high electric field with two sensing electrodes connected to the main capillary channel through two side detection channels. The principle of this conc ...

Pressure injection in continuous sample flow electrophoresis microchips

Martinus Gijs, Frédéric Lacharme

Pressure pulse injection is proposed as an alternative technique to electrokinetic injection for use in continuous sample flow electrophoresis microchips. During chip operation, sample and buffer solutions are electrokinetically driven near to the entrance ...
