Secular Light Curves of Comets C/2011 L4 Panstarrs and C/2012 S1 ISON Compared to 1P/Halley [PDF]
arXiv, 2013 We used 1329 observations of comet C/2011 L4 Panstarrs and 1897 observations of C/2012 S1 ISON to create the Secular Light Curves (SLCs), and to compare them to comet 1P/Halley (3172 observations). These comets are at the present time approaching perihelion. Thus the information contained in this report is preliminary.

How Meteor Showers Can Guide the Search for Long Period Comets [PDF]
arXivWith orbital periods longer than 200 years, most long-period comets (LPCs) remain undiscovered until they are in-bound towards perihelion. The comets that pass close to Earth's orbit are Potentially Hazardous Objects (PHOs). Those with orbital periods up to ~4000 years tend to have passed close to Earth's orbit in a previous orbit and produced a ...

Microscopy Research and Technique, EarlyView.ABSTRACT Haloxyfop‐R‐methyl (HRM) is extensively employed to control annual and perennial grass weeds. This study aimed to investigate the cyto‐genotoxic effects of HRM at concentrations of 1.19, 2.38, and 4.76 mg/L over various time intervals (24, 48, 72, and 96 h) on Allium cepa root.

Conditions for the formation of anomalous tail of comet
Open Astronomy, 2019 The time and velocity of ejection of dust particles of anomalous tails from cometary nuclei are determined. It is revealed that some comets cause the formation of an anomalous tail is the collision of their comet nucleus with other bodies of the Solar ...

Computed tomographic diagnosis of a fracture of the floor of the pelvis in a Thoroughbred foal
Equine Veterinary Education, Volume 35, Issue 2, Page 82-86, February 2023., 2023 Summary This case report describes the clinical and diagnostic imaging findings, treatment and outcomes of a 15‐day‐old Thoroughbred foal referred for the evaluation of severe left hindlimb lameness of 8 days' duration. Radiographic examination of the left hindlimb and transcutaneous ultrasonographic examination of the pelvis were unremarkable.
