Aerobic exercise with blood flow restriction for patients undergoing dialysis
This study demonstrated that blood flow restriction aerobic exercise performed during dialysis is both haemodynamically safe and efficacious for enhancing strength and physical function among patients with end-stage kidney disease. The findings positively support blood flow restriction as an adjunct to exercise for dialysis patients afflicted with marked physical impairment

Risk across design domains
Design processes involve risk: to life and limb if the product is unsafe, to the financial health of the company if the product is late, unsuccessful or simply the wrong product, as well as to the emotions and careers of the designers. Many of the risks are shared universally by all designers, but each different industry and each different project faces its own spectrum of serious and minor risks. Different industries have put their methodological effort into finding ways to mitigate the risks they recognise as important. As part of the Across Design project exploring similarities and differences between design processes in different industries, this paper examines how risks are perceived and handled in different types of design process, and proposes that designers and managers can usefully look to other industries for ways to handle risks that are more central for those other industries
Efficient optimisation of structures using tabu search
This paper presents a novel approach to the optimisation of structures using
a Tabu search (TS) method. TS is a metaheuristic which is used to guide local
search methods towards a globally optimal solution by using flexible memory
cycles of differing time spans. Results are presented for the well established
ten bar truss problem and compared to results published in the literature. In
the first example a truss is optimised to minimise mass and the results
compared to results obtained using an alternative TS implementation. In the
second example, the problem has multiple objectives that are compounded into a
single objective function value using game theory. In general the results
demonstrate that the TS method is capable of solving structural optimisation
problems at least as efficiently as other numerical optimisation approaches
Volatiles from biofumigant plants have a direct effect on carpogenic germination of sclerotia and mycelial growth of Sclerotinia sclerotiorum
Aims
Sclerotia of Sclerotinia sclerotiorum survive in soil and germinate to produce apothecia which release airborne ascospores. Current control methods rely predominantly on the use of fungicides to kill ascospores. The aim of this research was to identify potential biofumigation treatments which suppress sclerotial germination, providing a potential alternative and long-term approach to disease management.
Methods
Microcosm and in vitro experiments were conducted using dried and milled plant material from six different biofumigant crop plants to determine effects on carpogenic germination of sclerotia and mycelial growth of S. sclerotiorum.
Results
All biofumigant plants significantly reduced germination of S. sclerotiorum sclerotia in the microcosm experiments, but were less effective against larger sclerotia. In vitro experiments showed a direct effect of biofumigant volatiles on both the mycelial growth of S. sclerotiorum, and carpogenic germination of sclerotia, where the most effective treatment was B. juncea ‘Vittasso’.
Conclusions
It was clear from this study that biofumigant crop plants have potential as part of an integrated disease management system for control of S. sclerotiorum. The microcosm experiments described here provide a straightforward and reliable screening method for evaluating different biofumigants for activity
