Climate-driven variation in biotic interactions provides a narrow and variable window of opportunity for an insect herbivore at its ecological margin

Climate-driven geographic range shifts have been associated with transitions between dietary specialism and generalism at range margins. The mechanisms underpinning these often transient niche breadth modifications are poorly known, but utilization of novel resources likely depends on phenological synchrony between the consumer and resource. We use a climate-driven range and host shift by the butt

Determinants of serum half-lives for linear and branched perfluoroalkyl substances after long-term high exposure-A study in Ronneby, Sweden

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are persistent substances with surfactant and repellent properties. Municipal drinking water contaminated with PFAS had been distributed for decades to one third of households in Ronneby, Sweden. The source was firefighting foam used in a nearby airfield since the mid-1980s. Clean water was provided from December 16, 2013.AIMS: The purpose was

Circulating plasma microRNAs in systemic sclerosis-associated pulmonary arterial hypertension

Objectives: SSc-associated pulmonary arterial hypertension (SSc-APAH) is a late but devastating complication of SSc. Early identification of SSc-APAH may improve survival. We examined the role of circulating miRNAs in SSc-APAH. Methods: Using quantitative RT-PCR the abundance of mature miRNAs in plasma was determined in 85 female patients with ACA-positive lcSSc. Twenty-two of the patients had SSc

Continuity and change in forest restoration : A comparison of US ecology and forestry in the 1940s and 1990s

Previous research has paid little attention to the multiple meanings of the concept of forest restoration. To gain a more comprehensive view of forest restoration, this paper compares the US forest restoration debate of the 1940s and 1990s, in the disciplines of ecology and forestry. The paper focuses on historical approaches to pasts and futures, and on “sociotechnical imaginaries” providing soci

Detection and mitigation of deception attacks on cloud-based industrial control systems

In recent years, because the cloud can provide huge advantages regarding storage and computing resources, industry has been motivated to move industrial control systems to the cloud. However, the cloud also introduces major security challenges, since moving control systems to the cloud can enable attackers to infiltrate the system and establish an attack that can lead to damages and disruptions wi

Vänstern som tror på den starkes rätt – för Ryssland

Den antiamerikanska vänstern har fått en märklig ny sängkamrat efter Rysslands invasion av Ukraina: den ”realistiska” skolan inom internationella relationer, företrädd av den amerikanske professorn John Mearsheimer. Detta trots att realismen visat sig usel som prognosverktyg och att tron på den starkes rätt över den svage är något som annars brukar leda till protester – åtminstone mot USA, skriverDen antiamerikanska vänstern har fått en märklig ny sängkamrat efter Rysslands invasion av Ukraina: den ”realistiska” skolan inom internationella relationer, företrädd av den amerikanske professorn John Mearsheimer.

Symptoms, problems and quality of life in patients newly diagnosed with oesophageal and gastric cancer - a comparative study of treatment strategy

BACKGROUND: Patients with oesophageal and gastric cancer have a low likelihood of being cured and suffer from a broad spectrum of symptoms and problems that negatively affect their quality-of-life (QOL). Although the majority (67-75%) of patients at the time of diagnosis suffer from an incurable disease, research has primarily focused on the pre- and postoperative phase among patients treated with

RIFM fragrance ingredient safety assessment, octyl isobutyrate, CAS Registry Number 109-15-9

The existing information supports the use of this material as described in this safety assessment. Octyl isobutyrate was evaluated for genotoxicity, repeated dose toxicity, reproductive toxicity, local respiratory toxicity, phototoxicity/photoallergenicity, skin sensitization, and environmental safety. Data from read-across analog hexyl isobutyrate (CAS # 2349-07-7) show that octyl isobutyrate is

Recurrent risk of hospitalization among older persons with problematic alcohol use: A multiple failure-time analysis with a discontinuous risk model

Background and AimsOlder persons with problematic alcohol use vary in psychosocial functioning, age of onset for problem drinking and use of other drugs. The study measured the differential risks of all-cause, alcohol, polydrug and psychiatric-related repeated hospitalizations among older persons with problematic alcohol use.DesignA linked register-based cohort study with discontinuous multiple-fa

In this fourth episode of the podcast Nic and Rebecca invited Laura Hrastar to the mic and chatted with her about life and work at Max IV - which is a Swedish national laboratory producing brilliant synchrotron radiation for various research projects . Thereafter they take a closer look at the galaxy listed as the 31st object in the Messier Catalogue.

Climate Change, Disasters, and the Refugee Convention

Climate Change, Disasters and the Refugee Convention is concerned with refugee status determination (RSD) in the context of disasters and climate change. It demonstrates that the legal predicament of people who seek refugee status in this connection has been inconsistently addressed by judicial bodies in leading refugee law jurisdictions, and identifies epistemological as well as doctrinal impedim
