Characteristics of lightning-generated electric fields measured in the Bogotá Savanna, Colombia

open access: yesRevista UIS Ingenierías, 2017
In this paper, important features of electric fields produced by cloud-to-ground (CG) lightning flashes in the central region of Colombia are analyzed. This study is the first conducted in the country where more than 100 CG lightning flash signatures are

Love Stinks: The Association between Body Odors and Romantic Relationship Commitment

open access: yesBrain Sciences, 2021
Anecdotal reports indicate that women dislike their partner’s body odor (BO) during the breakdown of a relationship; however, whether disliking a partner’s BO is associated with intentions to break up has not been empirically tested.

A Frontal Thunderstorm With Several Multi‐Cell Lines Found to Produce Energetic Preliminary Breakdown

open access: yesJournal of Geophysical Research: Atmospheres, 2022
AbstractWe combine electromagnetic measurements with meteorological and lightning detection data to explain an observation of unusually strong preliminary breakdown (PB) produced by a thunderstorm system that developed along the Mediterranean Coast of Southern France in the early hours of 19 June 2013.

The forgotten tonsils—does the immune active organ absorb nanoplastics?

open access: yesFrontiers in Nanotechnology, 2022
Nanoplastics are defined as plastic particles broken down to extremely small sizes (1–100 nm) with unknown effects to the human body and immune system. Air and food exposure scenarios involving blood, lungs and intestine are considered in the literature.

Characterization of Hybrid Lightning Flashes Observed by Fast Antenna Lightning Mapping Array in Summer Thunderstorms

open access: yesAtmosphere
Using the observation data from Fast Antenna Lightning Mapping Array, we have sub-divided 288 hybrid flashes that are obviously different from traditional intracloud (IC) and negative cloud-to-ground (NCG) flashes into three types: IC–NCG lightning (85),
