A translation of L. Euler's "On the motion of comets in parabolic orbits, having the Sun in the focus" [PDF]

open access: yes, 2021
This is a translation from Latin of E840 'De motu cometarum in orbitis parabolicis, solem in foco habentibus', in which Euler addresses six problems related to comets in heliocentric parabolic orbits. Problem 1: Find the true anomaly of a heliocentric comet from the latus rectum of the orbit and the medium Earth to Sun distance.

Nickel oxide nanoparticles exposure as a risk factor for male infertility: “In vitro” effects on porcine pre-pubertal Sertoli cells

open access: yesFrontiers in Endocrinology, 2023
Lately, nickel oxide nanoparticles (NiO NPs) have been employed in different industrial and biomedical fields. Several studies have reported that NiO NPs may affect the development of reproductive organs inducing oxidative stress and, resulting in male ...

Constant strain accumulation rate between major earthquakes on the North Anatolian Fault

open access: yesNature Communications, 2018
Accumulation of interseismic strain may now be constrained by satellite observations. Here, the authors show that strain accumulation rates on the North Anatolian Fault are constant for the interseismic period indicating that lower-crustal viscosities ...

An international Delphi survey and consensus meeting to define the core outcome set for trigeminal neuralgia clinical trials

open access: yesEuropean Journal of Pain, Volume 27, Issue 1, Page 86-98, January 2023., 2023
Abstract Background Trigeminal neuralgia (TN) is an excruciating unilateral facial pain, which negatively affects patient's quality of life. Historically, it has been difficult to compare treatment efficacy due to the lack of standardized outcomes. In addition, patients' perspective has seldomly been acknowledged.

The role of space-based observation in understanding and responding to active tectonics and earthquakes

open access: yesNature Communications, 2016
Earthquake prone areas are now routinely monitored by satellites, which can map surface rupture and distribution of slip on faults. Here Elliottet al. review the latest advances in the field of spacebased earthquake observations showing how this is used ...

The Composition of Comets [PDF]

open access: yesSpace Science Reviews, 2015
This paper is the result of the International Cometary Workshop, held in Toulouse, France in April 2014, where the participants came together to assess our knowledge of comets prior to the ESA Rosetta Mission. In this paper, we look at the composition of the gas and dust from the comae of comets.
