Solvent-Free Coating Using MACO Bio-Based Reactive Diluent
The project performed utilizes methacrylated cardanol (MACO) and a linseed oil resin to test how different weight percentages of MACO affect coating performance. MACO is synthesized from a phenolic lipid extracted from cashew nut shells, which are a cashew industry waste product. Not only does it utilize a waste product, but being a bio-based reactive diluent means it can replace the use of volatile organic solvents that are harmful to both humans and the environment. Weight percentage samples of 0%, 10%, 20%, 30%, and 40% were used. Coatings were applied using a 6-mil drawn down bar, with samples being prepared for two different tests. Electrochemical impedance spectroscopy (EIS) and salt spray testing were utilized to determine which percentages performed the best. Based on the test results and ease of application, the 20 wt% samples performed the best out of all the samples
Finding the right rabbit to pull out of the hat: data management in CSIRO
CSIRO is one of the worldās largest and most diverse research agencies with staff located literally from one end of Australia to the other as well as internationally. As both a creator and a consumer of research data, CSIRO faces considerable data management challenges. To this end, the development of the CSIRO Data Management Service (DMS) Repository is a pivotal step in the right direction for managing CSIRO-generated data, third-party data and establishing vital links with research community portals such as Research Data Australia and the Atlas of Living Australia. From metadata mapping to collector and conversion tools, this presentation will discuss the experiences of the CSIRO Information Management & Technology (IM&T) team in applying new services and technologies to address the challenges of discovering, exchanging and re-using research data
Tram-Line filtering for retinal vessel segmentation
The segmentation of the vascular network from retinal fundal images is a fundamental step in the analysis of the retina, and may be used for a number of purposes, including diagnosis of diabetic retinopathy. However, due to the variability of retinal images segmentation is difficult, particularly with images of diseased retina which include significant distractors.
This paper introduces a non-linear filter for vascular segmentation, which is particularly robust against such distractors. We demonstrate results on the publicly-available STARE dataset, superior to Stareās performance, with 57.2% of the vascular network (by length) successfully located, with 97.2% positive predictive value measured by vessel length, compared with 57% and 92.2% for Stare. The filter is also simple and computationally efficient

The Northwest Tropical Atlantic Station (NTAS) : NTAS-15 Mooring Turnaround Cruise Report cruise on board RV Endeavor January 25 - February 13, 2016 Narragansett RI, USA - San Juan, Puerto Rico
The Northwest Tropical Atlantic Station (NTAS) was established to address the need for
accurate air-sea flux estimates and upper ocean measurements in a region with strong sea surface
temperature anomalies and the likelihood of significant local airāsea interaction on interannual to
decadal timescales. The approach is to maintain a surface mooring outfitted for meteorological
and oceanographic measurements at a site near 15Ā°N, 51Ā°W by successive mooring turnarounds.
These observations are used to investigate airāsea interaction processes related to climate
variability. The NTAS Ocean Reference Station (ORS NTAS) is supported by the National
Oceanic and Atmospheric Administrationās (NOAA) Climate Observation Program.
This report documents recovery of the NTAS-14 mooring and deployment of the NTAS-15
mooring at the same site. Both moorings used Surlyn foam buoys as the surface element. These
buoys were outfitted with two AirāSea Interaction Meteorology (ASIMET) systems. Each
system measures, records, and transmits via Argos satellite the surface meteorological variables
necessary to compute airāsea fluxes of heat, moisture and momentum. The upper 160 m of the
mooring line were outfitted with oceanographic sensors for the measurement of temperature,
salinity and velocity.
The mooring turnaround was done by the Upper Ocean Processes Group of the Woods Hole
Oceanographic Institution (WHOI), onboard R/V Endeavor, Cruise EN573. The cruise took
place between January 25 and February 13 2016. The NTAS-15 mooring was deployed on
February 2, and the NTAS-14 mooring was recovered on February 4. A 24-hour intercomparison
period was conducted on February 5, during which data from the buoy, telemetered
through Argos satellite system, and the shipās meteorological and oceanographic data were
monitored while the ship was stationed 0.2 nm downwind of NTAS-15 buoy. A similar
procedure was done at NTAS-14 but for only about 10 hours on the morning of February 4. This
report describes these operations, as well as other work done on the cruise and some of the precruise
buoy preparations.
Other operations during EN573 consisted in the recovery and deployment of the Meridional
Overturning Variability Experiment (MOVE) subsurface moorings array (MOVE 1 in the east,
and MOVE 3 and 4 in the west near Guadeloupe). Acoustic download of data from Pressure
Inverted Echo Sounders (PIES) was also conducted. MOVE is designed to monitor the integrated
deep meridional flow in the tropical North Atlantic.Funding was provided by the National Oceanic and Atmospheric Administration
