Electric vehicles have a potential to lower greenhouse gas emissions but still face challenges. This study asks what can be learned from the US automobile history. In 1900, there were three equal contenders in the US automotive industry: gasoline, electric and steam cars. Only a decade later, the gasoline car had achieved a crushing dominance. This dominance is often attributed to techno-economic

Birds, and especially raptors, are highly visual animals. Some of them have the highest spatial resolving power known in the animal kingdom, allowing prey detection at distance. While many raptors visually track fast-moving and manoeuvrable prey, requiring high temporal resolution, this aspect of their visual system has never been studied before. In this study, we estimated how fast raptors can se

Background: Certain immunoglobulins (Ig) are proposed to have protective functions in atherosclerosis.Objectives: We tested whether serum levels of IgG and IgM autoantibodies against malondialdehyde low density lipoprotein (MDA-LDL) are associated with clinical coronary heart disease (CHD) and unfavorable plaque characteristics.Methods: NORDIL was a prospective study investigating adverse cardiova

Resandet med tåg har ökat stadigt i Sverige de senaste 30 åren. Takten har varit cirka två-tre procent per år, och vi nu har mer än dubbelt så många resenärer. Med ökat fokus på klimatfrågan stiger resandet nu ännu snabbare. Ett problem som drabbar både resenärer och företag i Sverige är tågförseningar. Ett sätt att beskriva dessa är den andel av alla tåg som kommer fram mer än fem minuter för senTravel by train has increased steadily in Sweden the last 30 years. The pace has been about two to three percent per year, and we now have twice as many passengers. With growing awareness of the changing climate, the pace is increasing further. A problem that affects both passengers and businesses in Sweden is train delays. One way to describe these is as the share of trains that arrive less than

OBJECTIVE: Our study aims to evaluate hypertensive case management in South Africa's public health sector using simulated patients.METHOD: Our study describes interactions between hypertensive simulated patients and primary healthcare workers at 39 public sector healthcare facilities in two metropolitan centres in the Eastern and Western Cape Provinces of South Africa. Our analysis focus on 97 int

Some semelparous species show terminal investment by suicidal offspring provisioning. This requires internal cellular disintegration for the production of regurgitated food and in preparation for the sacrifice of the female body to the offspring, however, we have limited insights into the extent and costs of such physiological modifications. Extreme provisioning is hypothesized to be limited to re

Light kaonic atoms studies provide the unique opportunity to perform experiments equivalent to scattering at threshold, being their atomic binding energies in the keV range. High precision atomic X-rays spectroscopy ensures that the energy shift and broadening of the lowest-lying states of the kaonic atoms, induced by the strong interaction between the kaon and nucleus, can be detected. Kaonic hyd

A 30-membered library of amides based on the potent urotensin II (UII) receptor agonist FL104, has been synthesized from ten different carboxylic acids and three amines. A synthetic protocol producing the amides in 47-98% yield has been developed in which the purification involved only extractions and in a few cases filtration through an ion-exchange resin. It was found that 5 mg of starting mater

A flexible, multistep parallel synthesis of spiperone analogues is described. A library of 4-substituted piperidines, assembled utilizing reductive amination and acylation protocols, was alkylated either homogeneously or heterogeneously, exploiting a product release only concept, to afford an oxa-series of spiperone analogues. Screening of the products at 5-HT2 and D2 receptors revealed 5-HT(2A) a

The removal and degradation of refractory antibiotics in saline water by electrochemical and photo-electrochemical catalysis has emerged as a worldwide research hotspot. Aiming to improve degradation performance, most of the concerned studies focus on new sophisticated materials and modification methods on the single working electrode (anode or cathode). But the synergistic effects between anode a

Natural wetlands constitute the largest and most uncertain source of methane (CH4) to the atmosphere and a large fraction of them are found in the northern latitudes. These emissions are typically estimated using process ("bottom-up") or inversion ("top-down") models. However, estimates from these two types of models are not independent of each other since the top-down estimates usually rely on th

DN DEBATT 26/9. Vuxna bör följa uppmaningen från ungdomarna i Fridays for future-rörelsen och protestera eftersom det politiska ledarskapet är otillräckligt. Omfattande och långvariga påtryckningar från hela samhället behövs för att få de politiskt ansvariga att utöva det ledarskap som klimatkrisen kräver, skriver 171 forskare i samhällsvetenskap och humaniora.
