Laundry routine and resource consumption in Australia

Inconspicuous consumption, the habitual use of resources in daily routines, poses a challenge to sustainable consumption. For example, laundry is often the most environmentally demanding stage of clothing’s life cycle, consuming significant quantities of water, energy and chemicals. Laundry thus provides a prime example of inconspicuous consumption, from which to consider sustainability transition

Smoking as a major risk factor for cervical cancer and pre-cancer: Results from the EPIC cohort

A total of 308,036 women were selected from the European Prospective Investigation into Cancer and Nutrition (EPIC) study to evaluate the association between tobacco smoking and the risk of cervical intraepithelial neoplasia of grade 3 (CIN3)/carcinoma in situ (CIS) and invasive cervical cancer (ICC). At baseline, participants completed a questionnaire and provided blood samples. During a mean fol

Genetic and morphological differentiation across a contact zone between two postglacial immigration lineages of Helianthemum nummularium (Cistaceae) in southern Scandinavia

Helianthemum nummularium (L.) Mill. has two subspecies in southern Scandinavia, which differ in an indumentum character that is inherited as a Mendelian gene with two alleles. The dominant allele is the genetic basis for the key character of subsp. obscurum (absence of a dense felt of stellate hairs on the abaxial surface of the leaf), whereas the recessive allele is the genetic basis for the key

Modeling extreme dependence between European electricity markets

Electricity spot prices are characterized by sudden large movements, followed a few days later by an equally large movement in the opposite direction. These phenomena are called spikes (upward movements) and drops (downward movements). Recent research has suggested that the dynamics of the electricity spot prices can be accurately described by hidden Markov Regime Switching (MRS) models. Regime sw

Reconstruction of Holocene lake-level changes in Lake Igelsjon, southern Sweden

Pollen and sediment stratigraphic analyses of a transect of core sequences are used to reconstruct Holocene lake-level changes in Lake Igelsjon, southern Sweden. The pattern of changes seen in the records is related to climatic/hydrological changes and agrees principally with the pattern characteristically found in lakes in southern Sweden. However, compared with an earlier study based on isotopic

Association between testosterone levels and risk of future rheumatoid arthritis in men: a population-based case-control study.

OBJECTIVES: Rheumatoid arthritis (RA) is less common among men than women, and sex hormones have been suggested to play a part in the pathogenesis. Lower levels of testosterone have been demonstrated in men with RA, but it is not known if these changes precede the disease. METHODS: In a nested case-control study, using information and blood samples from a population-based health survey, we identif

On the stability of aqueous dispersions containing conducting colloidal particles.

We use a combination of simulations and a simple theoretical approach to investigate interactions between neutral conducting surfaces, immersed in an electrolyte solution. The study is conducted at the primitive model level, which necessitates the use of multiple image reflections. Our approximate theory is based on a classical density functional formulation of Poisson-Boltzmann theory. The same a

Haemophilus influenzae reside in tonsills and use IgD binding as an evasion strategy.

Haemophilus influenzae (Hi) causes respiratory tract infections and is also considered as a commensal, particularly in pre-school children. Tonsils from patients (n=617) undergoing tonsillectomy due to chronical infection or hypertrophy were examined. We found that 51 % of tonsils were positive for Hi, and in 95 % of cases analysed in detail (n=39) Hi resided intracellularly in the core tonsillar

Risk Identification on the Interface Between Business Case and Requirements

Motivation: The requirements engineering (RE) research community is aware of the importance of performing feasibility studies before starting requirements elicitation. Unfortunately, projects still frequently fail to achieve commercial success, responsibility is often unknown, and requirements engineers may be deemed responsible for mistakes made by others. Problem: There is neither empirical evid

Mineralisation of soft and hard tissues and the stability of biofluids.

Evidence is provided from studies on natural and artificial biofluids that the sequestration of amorphous calcium phosphate by peptides or proteins to form nanocluster complexes is of general importance in the control of physiological calcification. A naturally occurring mixture of osteopontin peptides was shown, by light and neutron scattering, to form calcium phosphate nanoclusters with a core-s

Risk factors for cardiovascular disease and future osteoarthritis-related arthroplasty: a population-based cohort study in men and women from Malmo, Sweden

Objective: To investigate the hypothesis that cardiovascular risk factors increase the likelihood of future osteoarthritis (OA)-related arthroplasty in adult men and women. Methods: Baseline cohort data on cardiovascular risk factors [age, socio-economic class, family history, obesity, smoking, glucose, cholesterol, blood pressure, and early cardiovascular disease (CVD) history] were linked to cli

Effect of Weight Maintenance on Symptoms of Knee Osteoarthritis in Obese Patients: A Twelve-Month Randomized Controlled Trial 1

Objective. To compare results of obese patients with knee osteoarthritis (OA) who, after an intensive weight loss regimen, received 1 year of either dietary support (D), a knee-exercise program (E), or "no attention" (C; control group). Methods. We conducted a randomized, 2-phase, parallel-group trial. A total of 192 obese participants with knee OA were enrolled; the mean age was 62.5 years and 81

Low-Variance Multitaper MFCC Features: A Case Study in Robust Speaker Verification

In speech and audio applications, short-term signal spectrum is often represented using mel-frequency cepstral coefficients (MFCCs) computed from a windowed discrete Fourier transform (DFT). Windowing reduces spectral leakage but variance of the spectrum estimate remains high. An elegant extension to windowed DFT is the so-called multitaper method which uses multiple time-domain windows (tapers) w

Improved utilization of fish waste by anaerobic digestion following omega-3 fatty acids extraction.

Fish waste is a potentially valuable resource from which high-value products can be obtained. Anaerobic digestion of the original fish waste and the fish sludge remaining after enzymatic pre-treatment to extract fish oil and fish protein hydrolysate was evaluated regarding the potential for methane production. The results showed high biodegradability of both fish sludge and fish waste, giving spec

Stable structural color patterns displayed on transparent insect wings.

Color patterns play central roles in the behavior of insects, and are important traits for taxonomic studies. Here we report striking and stable structural color patterns—wing interference patterns (WIPs) —in the transparent wings of small Hymenoptera and Diptera, patterns that have been largely overlooked by biologists. These extremely thin wings reflect vivid color patterns caused by thin film i

Long term effects of an intervention in the outdoor environment-a comparison of older people's perception in two residential areas, in one of which accessibility improvements were introduced

Walking and participating in activities outdoors in old age can be restricted both by the physical capacity of the individual and by the maintenance and/or the design of the outdoor environment. The purpose of this paper is to compare frequency of walking and frequency of activity outside the home, reported environmental barriers and valuation of the outdoor environment between two areas, in one o

Changes in body composition after 2 years with rheumatoid arthritis

Objectives: Rheumatoid arthritis (RA) is associated with cardiovascular disease (CVD). Possible predictors for CVD are early changes in body composition. We therefore evaluated changes in lean body mass (LBM), lean mass of arms and legs (LMAL), total body fat mass (BFM), and truncal fat distribution (FD) after 2 years with RA and possible predictors. Methods: We registered 63 (45 women) RA patient

Serum concentrations of perfluorinated alkyl acids and their associations with diet and personal characteristics among Swedish adults

ScopeIn this study, food is suggested as a major source of human exposure to perfluorinated alkyl acids (PFAA). We investigated relations between serum levels of PFAA in adults and diet/lifestyle factors nationwide in Sweden. Methods and resultsIn 2010-2011, adults (18-80 years, N = 270) recorded their diet for 4 days and answered a food frequency questionnaire. PFAA were measured in blood serum a
