While major mergers and their tidal debris are well studied, they are less common than minor mergers (mass ratios ≲ 0.3). The peculiar spiral NGC2782 is the result of a merger between two disk galaxies with a mass ratio of 4: 1 occurring 200 Myr ago. This merger produced a molecular and H I-rich, optically bright eastern tail and an H I-rich, optically faint western tail. Non-detection of CO in the western tail by Braine et al. suggested that star formation had not yet begun to occur in that tidal tail. However, deep Hα narrowband images show evidence of recent star formation in the western tail. Across the entire western tail, we find the global star formation rate per unit area (ΣSFR) to be several orders of magnitude less than expected from the total gas density. Together with extended FUV+NUV emission from Galaxy Evolution Explorer along the tail, this indicates a low global star formation efficiency in the tidal tail producing lower mass star clusters. The H II region that we observed has a local (few-kiloparsec scale) ΣSFR from Hα that is less than that expected from the total gas density, which is consistent with other observations of tidal debris. The star formation efficiency of this H II region inferred from the total gas density is low, but normal when inferred from the molecular gas density. These results suggest the presence of a very small, locally dense region in the western tail of NGC2782 or of a low-metallicity and/or low-pressure star-forming region. © 2012 The American Astronomical Society.

In the second half of September 2011 a neutrino beam from a CERN lab in Geneva, Switzerland shot 732 km to the National Institute of Nuclear Physics Gran Sasso lab in Italy seemed to travel 0.0025% faster through Earth than speed of light in a vacuum. Not looking at the accuracy of this disputed experiment it shows that neutrinos are very peculiar subatomic particles because they travel either with a speed very close to the speed of light, or at speed of light, or even above if the experiment turns out to be repeatable. This raises the question about the nature of neutrinos and if we can detect a feasible process that causes the extremely small mass of neutrinos that is obviously not subject to any relativistic mass increase. A new approach to the well-known simultaneity of relativity of events with Planck's quantization scale of length and time may solve the riddle for the strange nature of neutrinos and the unexpected mass feature they have. This discussion opens the horizon to hidden forms of energies throughout vacuum of space by introducing quantized rotary space-time elements and examining the relativity of simultaneity in a way it has never done before.

We are at a unique place in time where STEM initiatives are influencing the future economy; however, these initiatives are widening the gap between what students are being taught in school and the skills required for them to thrive in a new digital and hyper-connected economy. Education should not only provide knowledge of STEM content but also provide awareness of global trends that inspire students to learn more. To resolve this skills gap educators should seek to foster student engagement with an educational strategy where project management, creativity, interpersonal, global competency and leadership skills can be learned through open-ended projects that connect students to the evolving digital ecosystem. Our educational goal should be to develop student explorers, who have a mindful eye toward problem finding not just problem solving. © 2015, American Institute of Aeronautics and Astronautics.

Methadone is a synthetic opioid increasingly used for pain management, yet it can be challenging to use safely. The most serious and potentially fatal side effects of methadone are respiratory depression and cardiac arrhythmias. Preventing these side effects is of paramount importance to ensuring the safe use of methadone for pain management. The safe use of methadone is being guided by the US Food and Drug Administration (FDA), the Drug Enforcement Administration (DEA), the manufacturer of methadone (Roxane Laboratories, Inc., Columbus, OH, USA), the Institute for Safe Medication Practices (ISMP), and experts in the field of pain management. The purpose of this paper is to discuss actions taken by the FDA, DEA and the drug manufacturer and to review recommendations made by the ISMP and other experts for initiating, prescribing, dispensing, administering, and monitoring methadone in adults. The main emphasis is on translating practice recommendations into actions that healthcare practitioners should take to safeguard the use of methadone for pain management. © 2010 Maney Publishing.

This Study shows that combination of new dynamic measurement techniques can provide a totally different view of paper surface properties. Additives in precoat or topcoat can greatly influence these paper characteristics. Due to the variety of coating color recipes and coating application methods, understanding the influence additives can have on interfacial interactions will bring science to the art of predicting printability and subsequent converting steps. The end result is a better understanding of the various multiple interfacial interactions.. Dynamic measurement taken within one second of material contact can capture in real time, concurrent interfacial interactions. This interfacial know how derived from the paint industry can be used to form better models for developing a better understanding of paper surface improving processes and techniques. This improved understanding will lead to the development and application of new additive to better control of application and final product quality. Source
