Background. This case-control study was performed to evaluate whether adding first-trimester maternal serum testing to nuchal translucency measurement would improve the antenatal detection of Down's syndrome and decrease the number of women offered fetal karyotyping. Methods. In the Swedish Nuchal Translucency Trial 39,572 pregnant women were randomized to a routine scan at 12-14 gestational weeks

By exposing photosystem II (PSII) samples to an incrementing number of excitation flashes at room temperature, followed by freezing, we could compare the Mn-derived multiline EPR signal from the S-2 oxidation state as prepared by 1, 5, 10, and 25 flashes of light. While the S-2 multiline signals exhibited by these samples differed very little in spectral shape, a significant increase of the relaxa

Continuing our work toward a system mimicking the electron-transfer steps from manganese to P680+ in photosystem II (PS II), we report a series of ruthenium(II)-manganese(II) complexes that display intramolecular electron transfer from manganese(II) to photooxidized ruthenium(III). The electron-transfer rate constant (kET) values span a large range, 1 × 105-2 × 107 s-1, and we have investigated di

This chapter explores how algorithms produce aesthetic forms and dystopian configurations across Palestinian cyber and digital spaces. Through surveillance and erasure, algorithms operate as infrastructures of (in)visibility across social media and digital maps. While serving the Israeli system of control by making Palestinian users and contents hyper-visible to surveillance, algorithms ultimately

The pandemic put all underlying structural problems about the living conditions of older persons in Europe on display. The inadequate protection afforded to older persons during this crisis reflects the weak position of this group. Additionally, the growing ageing population in EU entails an urgent challenge to the union. In this chapter, I argue for what policies the EU needs to implement to ensu

Viljan att skydda växter och djur får ibland orimliga effekter. Det skriver flera företrädare för Moderaternas arbetsgrupp för en kommande miljöpolitik på DN debatt.Farlig polariseringDe tar bland annat upp viktiga frågor om ”människans plats i naturen”. Men konflikten mellan utveckling och miljö är en återkommande missuppfattning. Frågan om naturvården främst bör utgå från människans eller nature

Phasor measurement signals are used as only input to a wide-area power system stabilizer to increase interarea mode damping of the Icelandic system. Modal analysis and time simulations of a detailed model show that frequency difference as PSS input gives a damping improvement that is robust to drastic changes in system topology. Field data from phasor measurement units indicate high signal quality

Popular Abstract in Swedish I nuklearmedicinska mätningar registreras förekomsten av en radioaktiv substans, vilken tillförts kroppen, via de fotoner som substansen utsänder. I denna studie har använts tomografisk nuklearmedicinsk teknik, SPECT, som ger information om regional fördelning av radioaktivitet i tre dimensioner. Aktivitetsfördelningen avspeglar någon fysiologisk funktion, exempelvis geThe objective was to develop and validate methods for single photon emission computed tomography, SPECT, allowing quantitative physiological and diagnostic studies of lung and heart. A method for correction of variable attenuation in SPECT, based on transmission measurements before administration of an isotope to the subject, was developed and evaluated. A protocol based upon geometrically well de

Study Design Controlled laboratory study; cross-sectional. Background Postural control following anterior cruciate ligament reconstruction (ACLR) primarily has been investigated during static single-leg balance tasks. Little is known about dynamic postural control deficits post-ACLR. Objectives To compare dynamic postural control (bilaterally) in persons who have undergone ACLR and healthy control

Aluminium-titanium (Al/Ti) composite sheets were fabricated via asymmetric accumulative roll bonding (AARB), which capitalises on additional shear to enhance plastic deformation. Multi-layers of Al alloy (AA1050) and commercially-pure Ti sheets were alternatively stacked and rolled-bonded with varied roll diameter ratios (dr) ranging from 1 to 2, for up to four passes. Annealing of selected compos
