The effect of premixed carbon monoxide on diesel PCCI combustion

open access: yesNihon Kikai Gakkai ronbunshu, 2018
In this study, we focused on premixed charge compression ignition (PCCI) combustion with dual fuel of carbon monoxide (CO) and diesel fuel. The effects of CO as fuel on PCCI combustion characteristics were investigated based on engine tests and numerical

Endocrine modulation of primary chemosensory neurons regulates Drosophila courtship behavior.

open access: yesPLoS Genetics, 2022
The decision to engage in courtship depends on external cues from potential mates and internal cues related to maturation, health, and experience. Hormones allow for coordinated conveyance of such information to peripheral tissues.
