The impacts of HF and VHF radiation towards preliminary breakdown events in lightning flashes
, 2019 Even though the mechanisms pertinent to the generation of radiation in frequency range above 3 MHz (HF and VHF radiation) are not well understood, it is thought that this radiation is caused by the electrical breakdown of virgin air rather than by the ...

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

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