SARS‐CoV‐2 and pregnancy outcomes under universal and non‐universal testing in Sweden: register‐based nationwide cohort study

ObjectiveTo assess associations of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and pregnancy outcomes considering testing policy and test-positivity-to-delivery interval.DesignNationwide cohort study.SettingSweden.PopulationFrom the Pregnancy-Register we identified 88 593 singleton births, 11 March 2020–31 January 2021, linked to data on SARS-CoV-2-positivity from the Pu

MPC Feed-Forward for Constraint Handling

In a mineral concentrator, ore is milled and later separated into concentrate and tailing by a process called flotation. When a milling line abruptly stops, a significant inflow disturbance to the downstream flotation series is often observed. To avoid de-tuning the flotation level controller to handle the worst case scenario, we introduce a feed-forward model predictive controller (MPC) that cons

Photographing Chinese Indonesian Communities : Memory and Social Change in Post-conflict Aceh

Aceh is a unique region of Indonesia. In addition to being the site of a nearly three-decade-long conflict between GAM (Gerakan Aceh Merdeka) and the Indonesian state, it is also a special autonomous territory where sharia law is enforced. This political climate has cast a shadow over the province’s multicultural reality, relegating ethnoreligious minorities to a subservient position and restricti

FLASH radiotherapy and the associated dosimetric challenges

At Lund University and Skåne University Hospital in Lund, Sweden, we have, as the first clinic, modified a clinical Elekta Precise linear accelerator for convertible delivery of ultrahigh dose rate (FLASH) irradiation. Whereas recently published reviews highlighted the need for standardised protocols for ultra-high dose rate beam dosimetry to be able to determine the true potential of FLASH irradi

Solidified water at room temperature hosting tailored fluidic channels by using highly anisotropic cellulose nanofibrils

Highly anisotropic cellulose nanofibrils can solidify liquid water, creating self-supporting structures by incorporating a tiny number of fibrils. These fibrillar hydrogels can contain as much as 99.99 wt% water. The structure and mechanical properties of fibrillar networks have so far not been completely understood, nor how they solidify the bulk water at such low particle concentrations. In this

The inhomogeneous structure of water at ambient conditions

Small-angle X-ray scattering (SAXS) is used to demonstrate the presence of density fluctuations in ambient water on a physical length-scale of ≈1 nm; this is retained with decreasing temperature while the magnitude is enhanced. In contrast, the magnitude of fluctuations in a normal liquid, such as CCl 4, exhibits no enhancement with decreasing temperature, as is also the case for water from molecu

Hausdorff dimension of recurrence sets

We consider linear mappings on the 2-dimensional torus, defined by T ( x ) = A x ( mod 1 ) , where A is an invertible 2 × 2 integer matrix, with no eigenvalues on the unit circle. In the case det A = ± 1 , we give a formula for the Hausdorff dimension of the set { x ∈ T 2 : d ( T n ( x ) , x ) < e − α n for infinitely many n } .

Methodology developed for field observations of large events during the pandemic

The Events Research Programme (ERP) was a multi-disciplinary study undertaken during the COVID-19 pandemic to investigate SARS-CoV-2 transmission risks and mitigations around the reopening of mass events in the UK in 2021 – including a behavioural study, exploring how non-pharmaceutical interventions (NPIs), such as social distancing, pre-event virus testing, and the use of face coverings might en

How Thomas Bartholin the Younger Read His Rudbeck : A Forgotten Debate on Historical Method in Seventeenth-century Scandinavia

In 1689 the Danish royal antiquary Thomas Bartholin the Younger (1659–1690) published a celebrated antiquarian work on the attitudes, customs, and rituals of the pagan inhabitants of Scandinavia. It has been deemed significant both for influencing the development of the historical conception of the ‘Viking Age’ in the eighteenth and nineteenth centuries, and for introducing a rigorous source-criti

Brotherly Letters : A Literary Study of the Correspondences of Moroccan and Tunisian Male Writers (Early 20th Century)

Den här avhandlingen analyserar en korpus av publicerade personliga brev från första halvan av 1900-talet skrivna av manliga författare från Marocko och Tunisien. Studiens övergripande syfte är att undersöka och identifiera de publicerade brevens litterära egenskaper (genius) och estetiska autonomi (egenvärde) med hjälp av en narratologisk och stilistisk metod som fokuserar påintertextualitet och This dissertation deals with a corpus of published private letters from the first half of the 20th century written by male writers from Morocco and Tunisia. The overall purpose of the study is to investigate and identify the literary properties (literary genius) of the published letters and their aesthetic autonomy using a stylistic and narratological method that focuses on intertextuality and the

Aboke-pesa : Scaling up a mutual credit currency. Teaching Case

The case presents Aboke-pesa, a local complementary currency in a poor rural area of Western Kenya.The reader gets an insight into the economic context of rural areas in the Global South, the work of introducing digital community currencies through farmers’ cooperatives, one of the most common designs of these currencies (mutual credit systems or LETS) as well as the particular challenges digital

Contact Allergy to Allergens in the Swedish Baseline Series Over-represented in Diabetes Patients with Skin Reactions to Medical Devices : A Retrospective Study from Southern Sweden

Allergic contact dermatitis is reported among individuals using continuous glucose monitoring systems and insulin pumps. The aim of this study was to describe contact allergy patterns for allergens in the Swedish baseline series and medical device-related allergens among users. Contact allergy to baseline series allergens and isobornyl acrylate was compared between diabetes patients and dermatitis

Arginase release in hemolytic uremic syndrome affects the vasculature

Hemolysis is a cardinal feature of hemolytic uremic syndrome (HUS) and during hemolysis excess arginase 1 is released from erythrocytes. Increased arginase activity leads to reduced arginine, as it is converted to urea and ornithine, and thereby reduced nitric oxide bioavailability, with secondary vascular injury. In this study we investigated arginase release in HUS patients and laboratory models

The role of dispersal limitation in the forest biome shifts of Europe in the last 18,000 years

Aim: How the ability of plants to move towards newly favourable habitats (dispersal limitation) impacts the change of biome distribution and transition under fast climate warming is still debated. Analysing vegetation change in the past may help to clarify the relative importance of underlying ecological processes such as climate, biotic interactions, and dispersal. In this study, we investigated

Äldres rätt till fri rörlighet inom EU – uppehållsrättens diskriminerande verkan

Syftet med detta bidrag är alltså att kritiskt granska äldres rätt till fri rörlighetinom EU. Utgångspunkten för denna analys är artikel 3 FEU där centralavärden för EU såsom välfärd, fri rörlighet, icke-diskriminering, socialrättvisa, socialt skydd och jämställdhet mellan kvinnor och män betonas.Vårt bidrag i detta kapitel är att visa att såsom reglerna är utformade idagriskerar de att ha en kraf

Arachidonic acid and docosahexaenoic acid levels correlate with the inflammation proteome in extremely preterm infants

Background & aim: Clinical trials supplementing the long-chain polyunsaturated fatty acids (LCPUFAs) docosahexaenoic acid (DHA) and arachidonic acid (AA) to preterm infants have shown positive effects on inflammation-related morbidities, but the molecular mechanisms underlying these effects are not fully elucidated. This study aimed to determine associations between DHA, AA, and inflammation-r

Pattern of Risks for Psychiatric and Substance Use Disorders in the Offspring of Parents With Alcohol Use Disorder

OBJECTIVE: The authors sought to clarify the components of the familial liability to alcohol use disorder (AUD) by examining parent-offspring transmission in a large Swedish population sample. METHODS: To this end, 1,244,516 offspring in intact families with a mean age at follow-up of 37.7 years (SD=6.8) were examined. Hazard ratios for offspring of parents with AUD were calculated using Cox model
