An implementation of a small quantum absorption refrigerator in a circuit QED architecture is proposed. The setup consists of three harmonic oscillators coupled to a Josephson junction. The refrigerator is autonomous in the sense that it does not require any external control for cooling, but only thermal contact between the oscillators and heat baths at different temperatures. In addition, the set
X-ray and neutron crystallography, as well as cryogenic electron microscopy (cryo-EM), are the most common methods to obtain atomic structures of biological macromolecules. A feature they all have in common is that, at typical resolutions, the experimental data need to be supplemented by empirical restraints, ensuring that the final structure is chemically reasonable. The restraints are accurate f
In the light of recent developments in the design of structural materials, micro-architected heterogenous-structure metals are considered among most structurally efficient. In this work, a new technique for Local High Pressure Torsion (L-HPT) enabling the creation of heterogeneous structures through localised deformation processing in sheet metals by impeding a rotating punch is proposed. Using AA
Objective: To examine how well ultrasound assessed occipitoposterior (OP) position or high sagittal (HS) position in primiparous women with a prolonged first stage of labor predicts a vaginal delivery and the duration of labor. Design: Prospective observational study. Setting. Stavanger University Hospital, a secondary referral center in Norway. Population. 105 primiparous women with prolonged f
This paper stems from an inductive research problem: the support given to the military-deep state by the youth revolutionary movement in Egypt’s political upheavals of summer 2013. Why would the youth revolutionary movement choose to support the military-deep state’s political maneuverings, and what is the precise nature of this support? To answer these questions, this paper chooses to explore two
Objectives To ascertain if fetal head position on transabdominal ultrasound is associated with delivery by Cesarean section in nulliparous women with a prolonged first stage of labor. Methods This was a prospective observational study performed at Stavanger University Hospital, Norway, and Addenbrooke's Hospital, Cambridge, UK, between January 2012 and April 2013. Nulliparous pregnant women with a
The incorporation of caproic acid in the sn-1 position of phosphatidylcholine (PC) catalyzed by lipase from Rhizopus oryzae was investigated in a water activity-controlled organic medium. The reaction was carried out either as esterification or transesterification. A comparison between these two reaction modes was made with regard to product yield, product purity, reaction time, and byproduct form
Further improvements in the clinical care of our most vulnerable patients-preterm infants-are needed. Novel diagnostic and surveillance tools facilitate such advances. The GASMAS technique has shown potential to become a tool to, noninvasively, monitor gas in the lungs of preterm infants, by placing a laser source and a detector on the chest wall skin. It is believed that this technology will beco
Flying insects frequently navigate through environments of different complexity. In this study, buff-tailed bumblebees (Bombus terrestris L.) were trained to fly along tunnels of different widths, from 60 to 240 cm. In tunnel widths of 60 and 120 cm, bumblebees control their lateral position by balancing the magnitude of translational optic flow experienced in the lateral visual field of each eye.
Prostate cancer (PCa)is one of the first three causes of cancer mortality in Europe. Screening in asymptomatic men (aged 55–69 yr)using prostate-specific antigen (PSA)is associated with a migration toward lower staged disease and a reduction in cancer-specific mortality. By 20 yr after testing, around 100 men need to be screened to prevent one PCa death. While this ratio is smaller than for breast
Denna uppsats beskriver vilka kategorier av anställda som är undantagna från anställningsskydd i Sverige och Storbritannien. Fokus för uppsatsen är Storbritanniens ‘employee shareholder’ och Sveriges anställda i en företagsledande eller jämförbar ställning, eftersom dessa två kategorier ger upp delar av sitt anställningsskydd och får någon form av ersättning eller kompensation för detta. UppsatseThis essay describes which categories of employees that are exempted from employment protection in Sweden and the United Kingdom. The focus of the essay will be the UK’s employee shareholders and Sweden’s employees in a managerial or comparable position, since these two categories give up their protection and receive some form of compensation, and/or some other form of protection in return. The es
Bone contains diverse structures. In fast-growing large animals, fibrolamellar bone is formed first and is then gradually replaced by remodelled bone with secondary osteons. Using position-resolved X-ray diffraction and X-ray fluorescence as a 2D multimodal microscopy technique, the nature of biomineral nanocrystals is investigated in bovine bone. Systematic spatial variations are found, for examp
Rare-earth (RE) doped optical materials are distinguished by their unique optical and electronic properties. These characteristics are essential for various applications, including laser stabilization, and phosphors. However, the sensitivity of these materials to environmental factors and intrinsic defects necessitates a deep understanding. Grasping how these factors influence the refractive index

While the energy transition of the EU housing stock is now being intensified with the launch of the Renovation Wave, economic inequalities are increasing in many OECD countries, which has effects on housing-related inequalities and the demand of affordable housing. The Renovation Wave is thus an opportunity to improve housing quality for low-income households, but also entails risks for increased
