Colour polymorphic species with extensive ranges often exhibit large-scale geographic patterns of morph frequency variation. Because colour polymorphism is associated with correlated differences in multiple traits, such as thermal performance, a likely proximate explanation for such patterns is morph-specific responses to temperature variation. The colour polymorphic Blue-tailed damselfly Ischnura

Although media-fueled food scares are often described as linked to consumers’ food anxieties, previous studies of food consumption have failed to explore fully how foodscare reports add to consumers’ anxieties. Using a relational theory of risk and a narrative approach, this article highlights how food-scare reports, through various risk accounts, create anxiety-inducing stories where consumers ar

In skeletal muscle hormone-sensitive lipase (HSL) has long been accepted to be the principal enzyme responsible for lipolysis of intramyocellular triacylglycerol (IMTG) during contractions. However, this notion is based on in vitro lipase activity data, which may not reflect the in vivo lipolytic activity. We investigated lipolysis of IMTG in soleus muscles electrically stimulated to contract ex v

Hornets, the largest social wasps, have a reputation of being facultatively nocturnal. Here we confirm flight activity of hornet workers in dim twilight. We studied the eyes and ocelli of European hornets (Vespa crabro) and common wasps (Vespula vulgaris) with the goal to find the optical and anatomical adaptations that enable them to fly in dim light. Adaptations described for obligately nocturna

Nitrous oxide (N2O) is a potent greenhouse gas and of special concern in wastewater treatment. It is formed in biological wastewater treatment under both aerobic and anaerobic conditions. A major reason for high N2O emissions is low oxygen concentration during nitrification. In this full-scale study of N2O emissions from a sequencing batch reactor for treating digester supernatant, the oxygen conc

Tunas make sharp descents and ascents around dawn and dusk called spike dives. We examine spike dives of 21 southern bluefin tuna (Thunnus maccoyii) implanted with archival tags in the Great Australian Bight. Using a new way to categorize this behavior, we show that spike dives are similar among all the fish in the study. The dive profiles are mirror images at dawn and dusk and are precisely timed

The groin field built at Westhampton, Long Island, NY, in the 1960s and early 1970s has functioned as intended in protecting a once-vulnerable 4.8-km long segment of barrier beach that had experienced repeated breaching. In 1996-1997, a tapered groin transition to the west was created. The tapering included placement of fill in the existing groin compartments and on the adjacent beach. The combine

Mental health problems among adolescents have become a major public health issue, and it is therefore important to increase knowledge on the contextual determinants of adolescent mental health. One such determinant is the socioeconomic structure of the neighbourhood. The present study has two central objectives, (i) to examine if neighbourhood socioeconomic deprivation is associated to individual

Popular Abstract in Swedish Målet avhandlingen har varit att undersöka möjligheten att bygga en kvantdator i kristaller dopade med joner av sällsynta jordartsmetaller. Det har visat sig att sådana joner har en väldigt lång livstid, vilket är en förutsättning för de typer av experiment som har utförts i den här avhandlingen. För att ytterliggare förhindra att de känsliga tillstånden i jonerna störsThis thesis describes a number of coherent processes, such as quantum information processing, superradiance and electromagnetically induced transparency, which have been experimentally implemented using rare-earth-ion-doped crystals. The rare-earths are a class of elements that have in common, an atomic structure that allows for very long lifetimes as well as coherence times, both on optical trans

High-spin states in the neutron-deficient nucleus In-107 were studied via the Ni-58(Cr-52,3p) reaction. In-beam gamma rays were measured using the JUROGAM detector array. A rotational cascade consisting of ten gamma-ray transitions, which decays to the 19/2(+) level at 2.002 MeV, was observed. The band exhibits the features typical for smooth terminating bands that also appear in rotational bands

For a number of applications, gluten protein polymer structures are of the highest importance in determining end-use properties. The present article focuses on gluten protein structures in the wheat grain, genotype- and environment-related changes, protein structures in various applications, and their impact on quality. Protein structures in mature wheat grain or flour are strongly related to end-

OBJECTIVES: The true incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing laparoscopic radical prostatectomy is unknown. Our aim was to determine the incidence of symptomatic DVT and PE and the risk factors for these complications. METHODS: Fourteen surgeons from 13 referral institutions from both Europe and the United States provided retrospecti

Regime shifts in shallow lakes are typically characterized by submerged macrophyte (clear water regime) or phytoplankton (turbid regime) dominance. Climate warming is expected to affect water quality and facilitate turbidity in lakes, but we may also expect synergistic effects on organisms' interactions from climate and local specific dynamics in lakes. We here examined long-term changes in phytop

Colorectal cancer (CRC) is one of the most common forms of cancer worldwide, with an annual incidence of more than 1 million cases. Despite advancements in the management of CRC, mortality remains high. Accumulating evidence indicates that CRC is a heterogeneous disease, which affects outcome beyond what can be predicted by disease stage and other conventional prognostic factors. Thus, there is a

We have carried out a combined X-ray photoelectron spectroscopy (XPS), ultraviolet photoelectron spectroscopy(UPS), and scanning tunnelling microscopy (STM) study of the C-60-Si(1 1 1) interaction where the XPS/UPS spectrometer and STM are integrated on a single UHV system. This enables a direct comparison of the XPS/UPS spectra with the STM data and eliminates any uncertainty in C-60 coverage mea

Background: The evidence about nitrosamines and heme iron intake and cancer risk is limited, despite the biologic plausibility of the hypothesis that these factors might increase cancer risk. We investigated the association between dietary nitrosamines and heme iron and the risk of prostate cancer among participants of European Prospective Investigation into Cancer and Nutrition (EPIC). Methods: D
