Despite widespread metal pollution of coastal ecosystems, little is known of its effect on marine phytoplankton. We designed a co-cultivation experiment to test if toxic dose–response relationships can be used to predict the competitive outcome of two species under metal stress. Specifically, we took into account intraspecific strain variation and selection. We used 72 h dose–response relationship

We introduce a parameter space containing all algebraic integers β ∈ (1, 2] that are not Pisot or Salem numbers, and a sequence of increasing piecewise continuous function on this parameter space which gives a lower bound for the Garsia entropy of the Bernoulli convolution ν β . This allows us to show that dimH(ν β ) = 1 for all β with representations in certain open regions of the parameter space

Terephthalate polyesters such as poly(ethylene terephthalate) (PET) have been massively produced over the last few decades due to their attractive properties in multiple applications. However, due to their limited biodegradability, they have accumulated in landfills and oceans, posing an environmental threat. Enzymatic recycling technologies are predicted to generate long-term socioeconomic benefi

BACKGROUND: Poor adherence to antiretroviral therapy in adolescents living with HIV is a global challenge. One of the key strategies to improve adherence is believed to be the use of digital adherence tools. However, evidence is limited in this area. Our objective was to investigate the effectiveness of mobile phone text message reminders in improving ART adherence for adolescents.METHODS: The pre

This study in the Amhara and Oromia regions of Ethiopia assessed the outcomes of tuberculosis (TB) treatment among children younger than 15 years. Retrospective data were collected on treatment outcomes and their determinants for children with TB for the cohorts of 2012-2014 enrolled in 40 hospitals and 137 health centers. Chi-square tests, t-tests, and logistic regression were used for the analys

BACKGROUND: Effective tuberculosis (TB) control is the end result of improved health seeking by the community and timely provision of quality TB services by the health system. Rapid expansion of health services to the peripheries has improved access to the community. However, high cost of seeking care, stigma related TB, low index of suspicion by health care workers and lack of patient centered ca

Gardeners have always used plants of different origins, moving them around to new environments, working hard to make the plants survive and thrive under new conditions. In gardens, vitality is often regarded as an asset and a reason to cultivate certain plants. Many varieties that have spread over centuries are today regarded as ‘belonging’, as more or less ‘natural’, and even as heritage plants.

Background: Guidelines regarding whether tamoxifen should be prescribed based on women's cytochrome P450 2D6 (CYP2D6) genotypes are conflicting and have caused confusion. This study aims to investigate if CYP2D6 metabolizer status isa associated with tamoxifen-related endocrine symptoms, tamoxifen discontinuation, and mammographic density change. Patients and methods: We used data from 1440 health

Background: Research and practice are often considered as two different worlds with different values, which causes a gap between them. Involving professionals such as practitioners, managers, decision-makers, and policy-makers in research on ageing and health might address the gap between research and practice, strengthen the healthcare system, and increase older people’s possibilities for healthy

Background: The role of non-group A streptococci and Fusobacterium necrophorum in pharyngotonsillitis has been disputed and few prospective studies have evaluated the effect of antibiotic treatment. This study uses registry data to investigate the relation between antibiotic prescription for pharyngotonsillitis in primary healthcare and return visits for pharyngotonsillitis, complications, and ton

Eulerian stochastic fields (ESF) based transported PDF method has evolved as one of the general purpose methods for the numerical simulation of complex chemically reactive turbulent flows in which the effect of turbulence on the chemical reaction rates can be computed directly without the need of modeling. It is found that ESF method may suffer from violation of the element mass conservation law d

In the mid-twentieth century, Sweden distinguished itself as one of the most organized and participatory democracies in the world, with high levels of voting turnout and party membership. But in the late nineteenth century the situation was much the opposite – Sweden had for Western Europe a low degree of suffrage, and low political participation. To explain the turnaround, this paper explores ext

BACKGROUND: Recent whole genome sequencing studies report that up to 6% of the childhood cancer population harbour a pathogenic variant. Identification of families with hereditary cancer may improve early detection of cancer as well as treatment outcome. AIMS: The overall aim of this thesis was to investigate familial cancer risk in relatives of children with cancer and assess the prevalence of pa

Contemporary evidence suggests that climate change and other co-occurring large-scale environmental changes, such as eutrophication, will have a considerable impact on aquatic communities. However, the interactions of these environmental changes on trophic interactions among zooplankton remain largely unknown. Here we present results of a mesocosm experiment examining how a couple of zooplankton p
