The early Katian (Late Ordovician) reefs near Saku, northern Estonia and the age of the Saku Member, Vasalemma Formation

Reefs developed simultaneously during the latest Sandbian/earliest Katian global Guttenberg Isotopic Carbon Excursion (GICE) in several places across Baltoscandia. Latest Sandbian/earliest Katian patch reefs are also described from the Vasalemma Formation of northern Estonia. The Saku Member of the Vasalemma Formation was previously considered as a proximal facies related to the reefs. However, th

Multi-local livelihoods and food security in rural Africa

This article analyses household-based food transfers as an expression of multi-local livelihoods. Transfers of maize outside the co-resident household unit are analysed on the basis of data from 2857 smallholder households across nine African countries. The study complements a growing interest in the role of food transfers for urban food security, through considering the food security implications

Adult Age Differences in Covariation of Motivation and Working Memory Performance: Contrasting Between-Person and Within-Person Findings

Developmental theorists have proposed for a long time that the prevailing focus on stable individual differences has obstructed the discovery of short-term covariations between cognitive performance and contextual influences within individuals that may help to uncover mechanisms underlying long-term change. As an initial step to overcome this imbalance, we observed measures of motivation and worki

Prolonged refeeding improves weight maintenance after weight loss with very-low-energy diets

The aim of the present study was to test the hypothesis that a prolonged refeeding duration after successful very-low-energy diet (VLED)-induced weight loss beneficially affects weight development and eating behaviour. Patients (it 269) were recruited to a I-year obesity treatment programme with 12 weeks of an initial VLED. After the VLED, patients with 10 % weight loss were randomly allocated to

Complexity of quantum states in the two-dimensional pairing model

It is known that many-fermion systems, such as complex atoms and nuclei, reveal (at some level of excitation energy) local signatures of quantum chaos similar to the predictions of random matrix theory. Here, we study the gradual development of such signatures in a model system of up to 16 fermions interacting through short-range pairing-type forces in a two-dimensional harmonic trap. We proceed f

Chemical composition of anal droplets of the eusocial gall-inducing thrips Kladothrips intermedius

The eusocial Acacia gall-inducing thrips Kladothrips intermedius (Thysanoptera: Phlaeothripinae) secretes defensive anal droplets when threatened. In addition to harmful substances, droplets of other thysanopteran species are known to contain semiochemicals such as alarm pheromones and/or repellents against enemies. Both Kl. intermedius larval stages and adult castes (soldiers and dispersers) prod

Spectroscopic identification of ethanol-water conformers by large-amplitude hydrogen bond librational modes.

The far-infrared absorption spectra have been recorded for hydrogen-bonded complexes of water with ethanol embedded in cryogenic neon matrices at 2.8 K. The partial isotopic H/D-substitution of the ethanol subunit enabled by a dual inlet deposition procedure enables the observation and unambiguous assignment of the intermolecular high-frequency out-of-plane and the low-frequency in-plane donor OH

Acute otitis media in children-current treatment and prevention.

Acute otitis media (AOM) is the most common bacterial infection in children and has a very varied clinical spectrum, ranging from spontaneous resolutions to serious complications. The effect of antibiotics in AOM depends on the chosen outcome, but has been shown to reduce pain somewhat, and have a greater beneficial effect in severe cases of AOM. Today, not all episodes of AOM are treated with ant

Safety and Preliminary Efficacy of Ultrasound-guided Percutaneous Irreversible Electroporation for Treatment of Localized Pancreatic Cancer

Background: Irreversible electroporation (IRE) is a local tumor treatment. Thin needles are placed percutaneously around the tumor under ultrasound guidance. Short pulses of direct current sent through the tissue irreversibly increase cell membrane permeability leading to cell death. We report a phase I study assessing the safety of ultrasound guided percutaneous IRE in patients with localized pan

Exhaustion-related changes in cardiovascular and cortisol reactivity to acute psychosocial stress.

Prior findings indicate that individuals scoring high on vital exhaustion show a dysfunctional stress response (DSR), that is, reduced cortisol reactivity and habituation to psychosocial stressors. The main aim of the present study was to examine whether a DSR may be a vulnerability factor in exhaustion disorder (ED). We examined whether a DSR is present during the early stages of ED, and still is

Patients’ participation in decision-making in the medical field – ‘projectification’ of patients in a neoliberal framed healthcare system

This article focuses on patients’ participation in decision-making in meetings with healthcare professionals in a healthcare system, based on neoliberal regulations and ideas.Drawing on two constructed empirical cases, primarily from the perspective of patients, this article analyses and discusses the clinical practice around decision-making meetings within a Foucauldian perspective. Patients’ par

Do reproductive and hormonal risk factors for breast cancer associate with attendance at mammography screening?

PURPOSE: To determine whether reproductive and hormonal risk factors for breast cancer associate with mammography attendance. METHODS: We linked data from the Malmö Diet and Cancer Study to the Malmö mammography register (Sweden, 1992-2009). We analyzed 11,409 women (age 44-72) who were free of breast cancer at study entry and a total of 69,746 screening invitations. Generalized Estimating Equatio

A Direct Electron Transfer-Based Glucose/Oxygen Biofuel Cell Operating in Human Serum

We report on the fabrication and characterisation of the very first direct electron transfer-based glucose/oxygen biofuel cell (BFC) operating in neutral glucose-containing buffer and human serum. Corynascus thermophilus cellobiose dehydrogenase and Myrothecium verrucaria bilirubin oxidase were used as anodic and cathodic bioelements, respectively. The following characteristics of the mediator-, s

Study of photocurrent generation in InP nanowire-based p(+)-i-n(+) photodetectors

We report on electrical and optical properties of p(+)-i-n(+)photodetectors/solar cells based on square millimeter arrays of InP nanowires (NWs) grown on InP substrates. The study includes a sample series where the p(+)-segment length was varied between 0 and 250 nm, as well as solar cells with 9.3% efficiency with similar design. The electrical data for all devices display clear rectifying behavi

Effectiveness and Feasibility Associated with Switching to a Second or Third TNF Inhibitor in Patients with Psoriatic Arthritis: A Cohort Study from Southern Sweden.

Because new modes of action for the treatment of psoriatic arthritis (PsA) are emerging, it is important to understand the use of switching to a second or third antitumor necrosis factor (anti-TNF) agent. This study investigated drug survival and treatment response rates of patients with PsA undergoing second- and third-line anti-TNF therapy.

Cause and effect in biology revisited: Is Mayr’s proximate-ultimate dichotomy still useful?

Fifty years ago, Ernst Mayr published a hugely influential paper on the nature of causation in biology, in which he distinguished between proximate and ultimate causes. Mayr equated proximate causation with immediate factors (for example, physiology) and ultimate causation with evolutionary explanations (for example, natural selection). He argued that proximate and ultimate causes addressed differ
