... The dataset includes scanned seismic records collected during cruise 9209 of the RV Maurice Ewing (1992) using the Krupp-Atlas Hydrosweep sub-bottom echo-sounder (3.5 kHz). The dataset is composed both of the raw scanned images and processed scanned images. Seismic records were provided to the author of this work by the Lamont Doherty Earth Observatory (Earth Institute, Columbia University, USA). Processed ship-based Navigation Data acquired during the Maurice Ewing expedition EW9209 (1992) can be downloaded from the Marine Geoscience Data System: http://www.marine-geo.org/tools/search/Files.php?data_set_uid=11449

... Identification and quantification of Non Intentionally Added Substances (NIAS) at low concentrations and eventually their distribution on Low Density Polyethylene (LDPE) films is an important issue. As Raman spectroscopy techniques are innovative and sensitive analytical methods and do not require pretreatment and manipulation of the sample, these were used for the identification of NIAS in LDPE pellet and films, which are commonly used for food packaging applications. The aggregation state of NIAS in LDPE were observed by Raman imaging with micrometric resolution. Four main NIAS compounds were identified in granule and film surfaces by confocal Raman spectroscopy: calcite (CaCO3), calcium sulphate (CaSO4), polystyrene (PS) and titanium dioxide (TiO2) in anatase form. By a semi-quantitative evaluation of the inorganic NIAS, 9.93 mg/kg of CaCO3, 1.62 mg/kg of CaSO4 and 0.17 mg/kg of TiO2 were estimated. The experimental findings achieved by Raman analysis were confirmed by the results obtained by Inductively Coupled Plasma-Mass Spectrometry (ICP-MS). Moreover, the toxicity of the identified compounds was examined according to the Cramer rules.

... The single magnetron sputtering technology has great limitations in the further optimization of the mechanical properties of TiN films. High energy shot peening (HESP), as a simple and efficient surface nanotechnology, has been widely used in the aerospace, mechanical processing and other fields. After being impacted by the projectile, the surface of the substrate will undergo severe deformation that induces nanocrystallization of the surface grains, thus greatly enhancing the surface activity. Combining HESP with high power impulse magnetron sputtering (HIPIMS)to understand how HESP affects the growth of TiN films on a TA2 surface and whether it can improve the wear resistance of TiN films has important research significance.

... The Chocó department suffers from extraordinary amounts of alluvial gold mining resulting in increased river turbidity. A gap has been identified where a replicable means of identifying such turbidity was absent, and a developed method shrinks the gap with Landsat and Sentinel imagery; a GIS is used to assess the temporal mining change of Chocó and utilise a Normalised Difference Turbidity Index to quantify turbidity. Mitigating effects clouds had on results was a challenge, and time constraints meant additional in-situ values could not be acquired. Nonetheless, turbidity quantified easily using the index and related well to identified mining sites highlighted from NDVI change. Classifications were accurate when verified with photographic evidence and revealed mining on the Quito profoundly increased turbidity for the Atrato while also identifying other sites. The method used simple tools and open-source data that can benefit decision-makers and communities of such regions, allowing them to monitor their own rivers.
