- Stable isotope records from speleothems provide information on past climate changes, most particularly information that can be used to reconstruct past changes in precipitation and atmospheric circulation. These records are increasingly being used to provide "out-of-sample" evaluations of isotope-enabled climate models. SISAL (Speleothem Isotope Synthesis and Analysis) is an international working group of the Past Global Changes (PAGES) project. The working group aims to provide a comprehensive compilation of speleothem isotope records for climate reconstruction and model evaluation. The SISAL database contains data for individual speleothems, grouped by cave system. Stable isotopes of oxygen and carbon (delta O-18, delta C-13) measurements are referenced by distance from the top or bottom of the speleothem. Additional tables provide information on dating, including information on the dates used to construct the original age model and sufficient information to assess the quality of each data set and to erect a standardized chronology across different speleothems. The metadata table provides location information, information on the full range of measurements carried out on each speleothem and information on the cave system that is relevant to the interpretation of the records, as well as citations for both publications and archived data.

- Rationale Environmental enrichment, a paradigm investigated extensively in animal models, is an intervention, which by design facilitates motor, sensory, social, and cognitive activity. It has been shown to improve poststroke motor and cognitive function in animal models of stroke. This is the first study to attempt to translate this intervention from the laboratory to the clinical setting. Aims The overall aim of this pilot study is to test the feasibility of using environmental enrichment with stroke patients in a rehabilitation setting. The aim is to enrich the environment of stroke survivors in a rehabilitation ward and measure changes in their activity (physical, cognitive, and social activity). Design Prospective nonrandomized block design intervention study. Study In the control phase we will determine the change in activity levels of patients treated in a usual rehabilitation environment over time. In the intervention phase structured observational techniques (behavioural mapping) will be used to quantify the change in activity levels of patients exposed to environmental enrichment. Outcomes The primary outcome is change in activity level. Additional data collected on entry to and exit from the study will include: cognitive function using a battery of cognitive tests, general function using the Functional Independence Measure, mood using the Patient Health Questionnaire 9 and boredom using the Stroke Rehabilitation Boredom Survey. Quality of life will be assessed using the Assessment of Quality of Life 1 month postdischarge from rehabilitation. Australian New Zealand Clinical Trials Registry# ACTRN12611000629932.

- The Suaineadh project aims at testing the controlled deployment and stabilization of space web. The deployment system is based on a simple yet ingenious control of the centrifugal force that will pull each of the four daughters sections apart. The four daughters are attached onto the four corners of a square web, and will be released from their initial stowed configuration attached to a central hub. Enclosed in the central hub is a specifically designed spinning reaction wheel that controls the rotational speed with a closed loop control fed by measurements from an onboard inertial measurement sensor. Five other such sensors located within the web and central hub provide information on the surface curvature of the web, and progression of the deployment. Suaineadh is currently at an advanced stage of development: all the components are manufactured with the subsystems integrated and are presently awaiting full integration and testing. This paper will present the current status of the Suaineadh project and the results of the most recent set of tests. In particular, the paper will cover the overall mechanical design of the system, the electrical and sensor assemblies, the communication and power systems and the spinning wheel with its control system.
