The antimicrobial activity of manuka honey has been well documented (Molan, 1992a,b,c, 1997) [Molan, P.C., 1992. The antibacterial activity of honey. 1: the nature of the antibacterial activity. Bee World 73 (1) 5-28; Molan, P.C., 1992. The antibacterial activity of honey. 2: variation in the potency of the antibacterial activity. Bee World 73 (2) 59-76;(More)
Antimicrobial resistance continues to be a global issue in healthcare organisations. Honey has long been shown to possess wound healing and antimicrobial properties that are dependent on a number of physical and chemical properties of the honey. We tested the antimicrobial activity of a medicinal honey, Surgihoney® (SH) and two prototype modified honeys(More)
HYPOTHESIS To qualitatively assess the different acoustic signatures of an otologic drill burr-bone interface during temporal bone dissection on full thickness calvarial and thin tegmen bone. BACKGROUND An appreciable change in the sound generated by drilling occurs with progressive thinning of the bone during temporal bone dissection. To date,(More)
Rapid economic growth in Northwest China has been accompanied by a dramatic increase in carbon emissions. Based on the two-level Logarithmic Mean Divisia Index (LMDI) method, this study decomposes changes in energy-related carbon emissions in Northwest China during 1995–2012 from the regional and provincial perspectives. Further, by constructing an expanded(More)
The scenarios generated by energy systems models provide a picture of the range of possible pathways to a low-carbon future. However, in order to be truly useful, these scenarios should not only be possible but also plausible. In this paper, we have used lessons from historical energy transitions to create a set of diagnostic tests to assess the feasibility(More)
This study explores the critical notion of how feasible it is to achieve long-term mitigation goals to limit global temperature change. It uses a model inter-comparison of three integrated assessment models (TIAM-Grantham, MESSAGE-GLOBIOM and WITCH) harmonized for socioeconomic growth drivers using one of the new shared socioeconomic pathways (SSP2), to(More)
The coefficient of restitution (COR) is one of the most important standards in all bat-and-ball sports to study the ball suitability and bouncing characteristics. Currently, a demand exists for an improved analytical model for computing the COR, particularly when a new material is introduced. A viscoelastic ball known as a sliotar is taken from the Irish(More)
Taking a European Union focus, this paper explicitly models competing uses of biomass to quantify its contribution toward a sustainable low carbon model of economic growth. To this end, a state-of-the-art multisector multiregion modelling tool is combined with a specially developed bio-based variant of a well-known global database. Employing a decomposition(More)
