Partially Premixed Combustion (PPC) has been proved a high efficiency combustion concept, along with ultra-low soot and NOx emissions. However, the nature of high pressure rise rate prevents PPC from operating range extension and further practical use. This paper aims to optimize mixture preparation to achieve the benefits of PPC with the constraints of engine states through injection strategy dur

The volume of credit to Swedish households has grown twice as fast as incomes since the mid-1990s. This has resulted in both rising house prices and rising household debt. This column argues that these trends expose Sweden to important economic vulnerabilities. Curbing these vulnerabilities will require prompt action by the authorities.

Fredrik NG Andersson and Lars Jonung argue that the current push for fiscal activism is short-sighted. Instead, the Swedish case from the last 25 years shows that stable public finances combined with supply-side policies is the recipe for economic stability and growth.

High-temperature PEM fuel cells (HT-PEMFCs) are of current interest due to their favorable characteristics in relation to PEM fuel cells operating at a low temperature (LT-PEMFCs). The benefits concern poisoning of the CO catalyst, water management, thermal management and humidity issues. The major challenge facing these fuel cells is to have the membrane performing well at high temperature. This

Economic historians tend to explain US geographical development gaps in terms of industrialisation. But by the end of the 20th century, the richest counties had become specialised in services, rather than in manufacturing. This column evaluates how the service economy triggered this evident contrast between the urban and rural US. Market size causes localisation of non-agricultural activity, with

Sweden's fix of its banks in the early 1990s is considered a model for today’s policymakers. This column reviews the main features of the Swedish approach and discusses its applicability to today’s banking problems. Policy must be carried out swiftly and openly, aiming at saving banks, not their owners or managers.

In order to combat the effects of climate change, it is important to use a combination of solutions to achieve carbon neutrality as soon as possible. Carbon capture and sequestration is one such technology that can be used to significantly reduce the carbon footprint of many industrial plants. A mature technology for CO2 capture, amine-based post-combustion capture, is readily available today. How

We examine the causes and policy implications of strategic (willful) ignorance of risk as an excuse to overengage in risky health behavior. In an experiment on Copenhagen adults, we allow subjects to choose whether to learn the calorie content of a meal before consuming it, and measure their subsequent calorie intake. Consistent with previous studies, we find strong evidence of strategic ignoranceWe examine the causes and policy implications of strategic (willful) ignorance of risk as an excuse to over-engage in risky health behavior.

Two-particle correlation functions were measured for pp‾, pΛ‾, p‾Λ, and ΛΛ‾ pairs in Pb–Pb collisions at sNN=2.76 TeV and sNN=5.02 TeV recorded by the ALICE detector. From a simultaneous fit to all obtained correlation functions, real and imaginary components of the scattering lengths, as well as the effective ranges, were extracted for combined pΛ‾ and p‾Λ pairs and, for the first time, for ΛΛ‾ p

The spread of invasive, particularily bird-sown and red-fruited, non-native woody species in open calcareous conifer forests in Sweden is discussed and examplified with a survey of pine forests by Åhus in E Scania, southern-most Sweden. The survey area is a pine forest planted ca 100 years ago on calcareous sanddunes within which an area with private homes with gardens was built in the 1960’s to 1

All five accepted Swedish (and Scandinavian) species of the ’Depilata group’, now referred to Hieracium sect. Pulmonarioidea have been revised and a diagnostic key as well as descriptions and illustrations are provided. The geographic distribution of the species in Sweden is mapped, but it is noted that none of them has been collected since 1922. Lectotypes are designated for H. depilatiforme Dahl

Measurements of K(892)0⁎ and ϕ(1020) resonance production in Pb–Pb and pp collisions at sNN = 5.02 TeV with the ALICE detector at the Large Hadron Collider are reported. The resonances are measured at midrapidity (|y| < 0.5) via their hadronic decay channels and the transverse momentum (pT) distributions are obtained for various collision centrality classes up to pT = 20 GeV/c. The pT-integrated y

During the period from 2011 to 2013, a group from Mossornas Vänner made a field survey of bryophyte flora of Stora alvaret situated on island Öland in the Baltic Sea. The result of the survey was published in Journal of Bryology 2018 (see the reference at the end of the article). We analysed the occurrence of bryophyte species and variation in species richness across 674 plats (0.5 m x 0.5 m) in a

Endometriosis and Irritable Bowel Syndrome (IBS) are common conditions among young women of reproductive age. The etiologies to the diseases are uncertain, but multifactorial pathophysiology has been proposed for each of them. Many studies have examined the two conditions separately, but the literature on the associations between endometriosis and IBS is sparse. However, there is an increasing amo

Gastric bypass surgery has benefi cial effects on obesity-induced metabolic disturbances, but the underlying mechanisms remain unclear. As Wnt genes are both positively and negatively correlated with obesity-induced adipose tissue infl ammation and insulin resistance, our main aim is to reveal a potential role for Wnt signaling in the reversal of these metabolic consequences after gastric bypass s

Skildringen av den process 1958-1962 som ledde till att Lunds universitet införde särskilda akademiska högtidsdräkter (talarer), baserad på primärhandlingar i Universitetsarkivet.

Gastric bypass surgery improves type 2 diabetes, but the weight loss independent mechanisms remain elusive. We set out to unravel a potential benefi cial role of gastric bypass surgery on islets of Langerhans. Eight week old male C57Bl/6 mice were fed a high fat diet (60% kcal fat) for 14 weeks and subsequently subjected to Roux-en-Y gastric bypass (RYGB; n=16). Weight matched (WMS; n=13) and pair

Inflation-targeting central banks commonly fail to hit their official inflation targets, so targets are combined with a tolerance band which is either implicit or explicit. Taking the Swedish Riksbank as an example, this column argues that adopting an explicit tolerance band would better communicate to the public the central bank’s lack of full control over the rate of inflation and thus foster puInflation-targeting central banks commonly fail to hit their official inflation targets, so targets are combined with a tolerance band which is either implicit or explicit.
