Arctic marine litter: Composition and sources investigated by citizen scientist "super-users".

Combating the challenge of marine litter requires an understanding of its distribution and accumulation for mitigative measures, and its sources for targeted preventative measures. The latter is generally not well assessed through most beach litter registration protocols available to citizen scientists. Deep Dives were specifically developed to provide management with additional relevant data on the sources of and behaviours leading to littering in the Arctic.

How do technologies meet the needs of the writer with dyslexia? An examination of functions scaffolding the transcription and proofreading in text production aimed towards researchers and practitioners in education.

Technological reading and writing tools can help students with dyslexia improve their writing, but students do not use reading and writing functions as much as expected. However, research addressing relevant technological functions is scarce. This study explored the needs of writers with dyslexia and how technological writing tools developed for three Nordic languages meet these needs.

Beach litter sources around Nuuk, Greenland: An analysis by UArctic summer school graduate course students.

Modeling studies illustrate the potential for long-range transport of plastics into the Arctic, although the degree to which this occurs remains relatively undocumented. We utilised a teaching exercise at a UArctic summer school graduate course in Nuuk, Greenland to conduct a preliminary in-depth analysis of beach litter sources in the Nuup Kangerlua fjord. Students and instructors collected and analysed 1800 litter items weighing 200 kg from one location in the fjord and another at its mouth.

Modeling Differential Enthalpy of Absorption of CO with Piperazine as a Function of Temperature.

Temperature-dependent correlations for equilibrium constants (ln ) and heat of absorption (Δ) of different reactions (i.e., deprotonation, double deprotonation, carbamate formation, protonated carbamate formation, dicarbamate formation) involved in the piperazine (PZ)/CO/HO system have been calculated using computational chemistry based ln values input to the Gibbs-Helmholtz equation.
