Spectrophotometry and structural analysis of 5 comets [PDF]

, 2002
We discuss the morphology and spectrophotometry of 5 comets visible in August, 2001. We decompose comae into coma profiles and azimuthally renormalized images, in which general and local features are quantitatively comparable. Comet 19P/Borrelly showed a strong gas fan toward the solar direction, but no detectable gas in the tail.

The Dust Tail of Asteroid (3200) Phaethon

, 2013
We report the discovery of a comet-like tail on asteroid (3200) Phaethon when imaged at optical wavelengths near perihelion. In both 2009 and 2012, the tail appears >=350" (2.5x10^8 m) in length and extends approximately in the projected anti-solar ...

Psychedelic‐assisted treatment for substance use disorder: A narrative systematic review

Addiction, EarlyView.
Abstract Background and aims This is the first systematic review of the extant literature on all major psychedelic‐assisted treatment for alcohol use disorder (AUD), tobacco use disorder (TUD) and other substance use disorders (SUD). We aimed to summarise the evidence for efficacy of psychedelic‐assisted treatment for AUD, TUD, and SUD; to evaluate its

DNA damage in BALB/c mice infected with Lacazia loboi and its relation to nutritional status

Journal of Venomous Animals and Toxins including Tropical Diseases, 2015
Background Jorge Lobo’s disease, also known as lacaziosis, is a cutaneous-subcutaneous mycosis with chronic evolution. It is caused by the fungus Lacazia loboi. Herein we report a study that relates the genotoxicity caused by L.

Tails of a Recent Comet

, 2010
Drain away the earth's oceans and a global pattern of great ridges appears. Adjacent to these continental and undersea mountain ranges are layers of silt and clay, so thick that they fill the gaps between ridges, creating extensive plateaus. Ranging across this planet's higher latitudes are thousands of tiny replicas of these ridge systems. These esker

The Dual Roles of Lamin A/C in Macrophage Mechanotransduction

Cell Proliferation, EarlyView.
Compressive force can inhibit the expression of lamin A/C, SUN1 and SUN2 in macrophages. Lamin A deficiency may participate in mechanotransduction within macrophages through two distinct mechanisms. ABSTRACT Cellular mechanotransduction is a complex physiological process that integrates alterations in the external environment with cellular behaviours ...

Safety evaluation of the food enzyme tannase from the non-genetically modified <i>Aspergillus</i> sp. strain TAN 206. [PDF]

EFSA J
Abstract The food enzyme tannase (tannin acylhydrolase; EC 3.1.1.20) is produced with the non‐genetically modified Aspergillus sp. strain TAN 206 by Shin Nihon Chemical Co., Ltd. The food enzyme is free from viable cells of the production organism. It is intended to be used in two food manufacturing processes. Dietary exposure was estimated to be up to

Initial overview of disconnection events in Halley's Comet 1986 [PDF]

We present an initial overview of the disconnection events (DE's) in Comet Halley in 1986. Although disconnection events are arguably the most spectacular of all dynamic comet phenomena, the mechanisms by which they occur are not fully understood.

Modelling the light-curve of KIC 12557548b: an extrasolar planet with a comet like tail

, 2013
An object with a very peculiar light-curve was discovered recently using Kepler data. Authors argue that this object may be a transiting disintegrating planet with a comet like dusty tail. We calculate the light-curves of stars with such planets and take

Indirect solar wind measurements using archival cometary tail observations [PDF]

, 2018
The paper addressed to the problem of the solar wind behaviour during the Maunder Minimum. Records on plasma tails of comets would allow to shed light on the physical parameters of the solar wind in the past. We analyse descriptions and drawings of comets to the eighteenth century.
