Observation and Analysis of Comet Tails [PDF]

open access: yesInternational Astronomical Union Colloquium, 1988
AbstractDetails of H2O and dust production in P/Halley are mainly derived from amateur observations of cometary tails, leading to a gas/dust mass-ratio. The rotational period (2.21 day) is also found from amateur observations. Velocity and acceleration of the plasma and velocity and direction of the solar wind are also derived, together with size and ...

Heavy‐duty conceptual engineering

open access: yesNoûs, EarlyView.
Abstract Conceptual engineering is the process of assessing and improving our conceptual repertoire. Some authors have claimed that introducing or revising concepts through conceptual engineering can go as far as expanding the realm of thinkable thoughts and thus enable us to form beliefs, hypotheses, wishes, or desires that we are currently unable to ...

Cytotoxic Effect of Nefazodone on HepG2 Cell Line and the Reliability of Comet Assay to Determine Genotoxicity.

open access: yesAl-Mustansiriyah Journal of Pharmaceutical Sciences, 2019
Nefazodone is atypical antidepressant which was manufactured by Bristol-Myers Squibb in 1994 to avoid the adverse effects associated with other antidepressants, including nausea, sedation, insomnia, cardiovascular toxi-city, weight gain and dysfunction.

Mosaic CCD method: A new technique for observing dynamics of cometary magnetospheres [PDF]

open access: yes
On April 29, 1990, the plasma tail of Comet Austin was observed with a CCD camera on the 105-cm Schmidt telescope at the Kiso Observatory of the University of Tokyo. The area of the CCD used in this observation is only about 1 sq cm.

A novel microcapsule composite Spherulites Peony Superior Retinol mitigates UVB‐induced skin damage in vitro and in vivo

open access: yesPhotochemistry and Photobiology, EarlyView.
This study explored the role of a novel microcapsule composite Spherulites Peony Superior Retinol (SPSR) on skin damage induced by UVB. The results of in vitro and human efficacy assays further demonstrate that SPSR is beneficial in replenishing skin hydration, promoting epidermal cell growth, soothing skin redness and sensitivity, reducing ROS ...

Molecular ions in comet tails

open access: yesThe Astrophysical Journal, 1976
Band intensities of the molecular ions CH/sup +/, CO/sup +/, N/sub 2//sup +/, and H/sub 2/O/sup +/ have been determined on an absolute scale from tail spectra of comet Kohoutek (1973f) and comet Bradfield (1974b). Photoionization and photodissociation rates have been computed for CH, CO, and N/sub 2/.
