A five-axis parallel kinematic mirror unit for soft X-ray beamlines at MAX IV

With the introduction of the multi-bend achromats in the new fourth-generation storage rings the emittance has decreased by an order of magnitude resulting in increased brightness. However, the higher brightness comes with smaller beam sizes and narrower radiation cones. As a consequence, the requirements on mechanical stability regarding the beamline components increases. Here an innovative five-

Corona är ett hot mot Sveriges säkerhet

En infektionssjukdom som covid-19 hotar både den mänskliga säkerheten och den nationella säkerheten. En politisk instabilitet till följd av en dålig ekonomi, minskat förtroende för samhällsinstitutioner, generell demoralisering samt rädsla, kan också ge konsekvenser som direkt hotar Sveriges säkerhet, skriver Ardavan Khoshnood, läkare och kriminolog.An infectious disease such as COVID-19 threatens both human security and national security. Political instability as a result of poor economy, diminished confidence in institutions, general demoralization and fear can also have consequences that directly threaten Sweden’s security, writes Ardavan Khoshnood, physician and criminologist.

Metabolomic Signature of Early Vascular Aging (EVA) in Hypertension

Arterial stiffening is a hallmark of early vascular aging (EVA) syndrome and an independent predictor of cardiovascular morbidity and mortality. In this case-control study we sought to identify plasma metabolites associated with EVA syndrome in the setting of hypertension. An untargeted metabolomic approach was used to identify plasma metabolites in an age-, BMI-, and sex-matched groups of EVA (n

Stalin's Double Edged Game : Soviet Bureaucracy and the Raoul Wallenberg Case 1945-1952

Raoul Wallenberg, the courageous Swedish financier and trade executive turned diplomat who saved thousands of Jews in Hungary in 1944, was arrested in January 1945 by the Soviet military counterintelligence, incarcerated in the Lubianka prison in Moscow, and later executed for reasons that remain obscure to this day. Drawing on recently declassified Soviet encrypted cables and a wide array of Sovi

Processområdets betydelse vid spricktillväxt.

Brottmekaniska processer ar något som intresserat människor i alla tider. Ibland har det varit för att vinna en fördel t ex vid tillverking av flintverktyg och malmbrytning, men oftast for att förhindra mekanisk kollaps. I det senare fallet kan oförsiktighet resultera i spruckna tallrikar eller trasiga fönster, men ocksa i allvarligare saker som brott i flygplansvingar eller fartygsskrov som i värBrottmekaniska processer ar något som intresserat människor i alla tider.

Towards sustainability with building services systems : – by focusing on material choices, energy use and thermal indoor climates in residential buildings

För att en utveckling ska anses hållbar måste mål ur såväl sociala, ekonomiska som miljömässiga aspekter vara uppfyllda. Det svenska miljömålssystemet, baserat på Agenda 2030, innehåller 16 miljökvalitetsmål och ett antal etappmål. För genomförande och uppföljning ansvarar åtta myndigheter, av vilka Boverket har ansvar för målet ”En god bebyggd miljö”. Faktorer som har valts att studera är inomhusFor a development to be considered sustainable, social, economic and environmental requirements must be met. The Swedish sustainable development goals, based on Agenda 2030, contain 16 national environmental quality goals. The National Board of Housing, Building and Planning is responsible for achieving the goal "A good built environment". Essential factors chosen for studies are: indoor environme

Whole body composition analysis by the BodPod air-displacement plethysmography method in children with Phenylketonuria shows a higher body fat percentage

Background Phenylketonuria (PKU) causes irreversible central nervous system damage unless a phenylalanine (PHE) restricted diet with amino acid supplementation is maintained. To prevent growth retardation, a protein/amino acid intake beyond the recommended dietary protein allowance is mandatory. However, data regarding disease and/or diet related changes in body composition are inconclusive and re

Fatal cerebral edema associated with serine deficiency in CSF

Two young girls without a notable medical history except for asthma presented with an acute toxic encephalopathy with very low serine concentrations both in plasma and cerebrospinal fluid (CSF) comparable to patients with 3-phosphoglycerate dehydrogenase (3-PGDH) deficiency. Clinical symptoms and enzyme measurement (in one patient) excluded 3-PGDH deficiency. Deficiencies in other serine biosynthe

Hydrolysed formula is a risk factor for vitamin K deficiency in infants with unrecognised cholestasis

OBJECTIVES:: Vitamin K deficiency (VKD) may cause life-threatening haemorrhages, especially in breast-fed infants with unrecognised cholestasis. Interestingly, hypoallergenic formulas appear overrepresented in reported cases of VKD bleeding (VKDB) in formula-fed infants. We therefore assessed whether the risk of VKD in formula-fed infants with cholestasis is associated with hypoallergenic formulas

Magnetic resonance imaging pattern recognition in hypomyelinating disorders

Hypomyelination is observed in the context of a growing number of genetic disorders that share clinical characteristics. The aim of this study was to determine the possible role of magnetic resonance imaging pattern recognition in distinguishing different hypomyelinating disorders, which would facilitate the diagnostic process. Only patients with hypomyelination of known cause were included in thi

Multicentre age-related reference intervals for cerebrospinal fluid serine concentrations : Implications for the diagnosis and follow-up of serine biosynthesis disorders

The disorders of serine biosynthesis are a group of inborn errors of metabolism characterised by congenital microcephaly, seizures and severe psychomotor retardation. Although these disorders are rare the prompt recognition of serine deficiency is important as these disorders are treatable. The diagnosis is based on decreased concentrations of serine in cerebrospinal fluid (CSF). It has previously
