Sexual activity is important to older adults (65 +). Breathlessness affects about 25% of older adults but impact on sexual activity is unknown. We evaluated the relationships between breathlessness and sexual inactivity and self-reported health among older community-dwelling adults in the Australian Longitudinal Study of Ageing. Associations between self-reported breathlessness (hurrying on level
Permafrost thaw can substantially increase the total export of dissolved organic carbon (DOC) to aquatic systems. The effects for bio- and photo-degradable DOC, however, are poorly known, because previous studies have mainly targeted lakes and streams which are indirectly affected by permafrost, while direct experimental work on permafrost thaw is lacking. We thus incubated permafrost cores from a
The entropy generation analysis of fully-developed turbulent heat transfer flow in inward helically corrugated tubes was numerically performed by using a Reynolds stress model. The simulations were conducted for a smooth tube and five cases of corrugated tubes with Reynolds number (Re) ranging from 10,020 to 40,060 at a constant wall temperature condition. The effects of corrugation pitch and heig
Randomised clinical trials are the gold standard for testing the effectiveness of clinical interventions. However, increasing complexity and associated costs may limit their application in the investigation of key cardiovascular knowledge gaps such as the re-evaluation of generic pharmacotherapies. The registry-based randomised clinical trial (RRCT) leverages data sampling from nationwide quality
The polyether ionophore salinomycin has recently captured much interest due to its potent activity against multi-drug resistant cancer cells and cancer stem cells. Previous studies have shown that either acylation of the C20 position or esterification/amidation of the C1 carboxylate moiety is beneficial in terms of biological properties. In this paper, we present the first analogs combining such m
PurposeThe purpose of this paper is to describe and analyze the foundation of higher education policies that have promoted entrepreneurship in Sweden since the mid-1990s.Design/methodology/approachTo do this, the authors use Bacchi’s (1999) “What’s the problem?” approach. A central assumption of which is that perceptions of a problem affect how its solution looks. Bacchi’s approach is described as
Background: The naturally occurring male-to-female (M/F) ratio at birth is 1.05. Higher ratios found primarily in countries across Asia have been attributed to prenatal sex selection due to son preference. There is growing evidence that sex-selective practices continue following migration; however, little is known about these practices following migration to Australia.Methods: In this population-b
The recent, rich scholarship on rhythms, following in the wake of Lefebvre’s book Éléments de rythmanalyse (1992), proves that rhythmanalysis is an important sensitising notion and research technique. Despite its increasing recognition, however, rhythmanalysis has not yet become a proper science as its proponents had hoped. In this article, we argue that rhythmanalysis could benefit from being fur
The scale and complexity of contemporary sustainability challenges necessitates interdisciplinarity in research and pluralism in practice. In recent year, however, a strong natural science hegemony has predominantly framed our understanding of the dynamics of nature and society. This strong hegemonic conceptualization of global predicaments is troublesome given both the drivers of sustainability c
This paper reports a numerical investigation on the effect of cavity geometry on fuel transport and mixing processes in a scramjet combustor with a single rear-wall-expansion cavity. The numerical solver and the LES methods were validated against available experimental data and the numerical results were shown in good agreement with the experiments. Effect of the cavity rear wall height on the non
Lakes and wetlands, common ecosystems of the high northern latitudes, exchange large amounts of the climate-forcing gases methane (CH4) and carbon dioxide (CO2) with the atmosphere. The magnitudes of these fluxes and the processes driving them are still uncertain, particularly for subarctic and Arctic lakes where direct measurements of CH4 and CO2 emissions are often of low temporal resolution and
OBJECTIVES: The purpose of this study was to assess the hypothesized association between persistent organochlorine compounds through the consumption of fatty fish from the Baltic Sea (at the Swedish east coast) and low birthweight.MATERIALS AND METHODS: During the period 1973-1991, 72 cases of low birthweight (1500-2750 g) were selected from among infants born to fishermen's wives within a cohort
