We investigated the wear characteristics and clinical performance of four different total hip joint articulations in 114 patients. Wear and migration was measured by roentgenstereophotogrammetric analysis at five years or at the last follow-up. The mean annual wear was 0.11 mm for a stainless steel/Enduron articulation, 0.34 mm for stainless steel/Hylamer cup, 0.17 mm for zirconium oxide ceramic/E

This paper presents a wideband CMOS power amplifier intended for cellular handset applications. The circuit exploits injection locking to achieve a power gain of 20.5dB from a single stage amplifier. The maximum output power of 29dBm, with a peak drain- and power-added-efficiency (PAE) of 66% and 64%, respectively, occurs at a center frequency of 2GHz with a 3V supply. A cross-coupled cascode topo

Three young men were trapped in a car at the bottom of a canal at two meters depth, after losing control of their vehicle. They were brought up by rescue divers and found in cardiac arrest. One of three patients had return of spontaneous circulation (ROSC), at 47 min after the accident. This sole survivor had the longest submersion time of the three and he received continued mechanical chest compr

The crustal segment Volgo-Uralia is the least known part of the East European Craton. Its crystalline crust is hidden beneath a thick Neoproterozoic to Phanerozoic cover but disclosed by thousands of drill holes. In conjunction with the recent "Tatseis" reflection seismic profile, we conducted the first isotopic study of the Bakaly granitoid block in eastern Volgo-Uralia, which represents a subsur

Spatial multiplexing using Massive MIMO has been shown to have very promising properties, including large gains in spectral efficiency and several orders of magnitude lower transmit power, as compared to today's access schemes. The properties of massive MIMO have been studied mostly for theoretical channels with independent and identically distributed (i.i.d.) complex Gaussian coefficients. To eff

Våldtäkt kränker internationella mänskliga rättigheter; detta fastslår globala och regionala MR-mekanismer tydligt. Stater har en skyldighet att utreda, åtala och straffa våldtäktsfall. Men när det gäller att definiera vad våldtäkt är, vilka gärningar stater är förpliktigade att beivra, erbjuder de internationella mekanismerna knapp vägledning. Den europeiska domstolen för mänskliga rättigheter tiRape violates international human rights law; global and regional human rights mechanisms clearly establish this. There is an obligation on states to investigate, prosecute and punish instances of rape. When it comes to defining what rape is, which acts states are obliged to prosecute the international mechanisms provide little guidance though. The European Court of Human Rights provides the most

Håller Sverige på att glida isär, fragmenteras eller är sprickorna i välfärden få och begränsade? Det är svårt att bortse från att de senaste 30 årens utveckling har inneburit stora förändringar i den välfärdsstat som utvecklades främst efter andra världskriget. I vissa avseenden har skyddsnäten blivit glesare. Utvecklingen har varit särskilt markant efter den ekonomiska krisen i början av 1990-ta

Importance: Lack of arachidonic acid (AA) and docosahexaenoic acid (DHA) after extremely preterm birth may contribute to preterm morbidity, including retinopathy of prematurity (ROP).Objective: To determine whether enteral supplementation with fatty acids from birth to 40 weeks' postmenstrual age reduces ROP in extremely preterm infants.Design, Setting, and Participants: The Mega Donna Mega trial,

The silicon isotope composition of biogenic silica (δ30SiBSi) in the ocean is a function of the δ30Si of the available dissolved Si (DSi; H2SiO4), the degree of utilisation of the available DSi, and, for some organisms, the concentration of DSi. This makes δ30SiBSi in sediment archives a promising proxy for past DSi concentrations and utilisation. At steady-state, mean δ30SiBSi must equal a weight

The project started with a section called Clarification Of The Task. The purpose was to investigate how big of a problem domestic flooding is and what the cause is. This was done by gathering information from different organizations and companies. Once we knew the problems we tried to understand the water systems that are the main failure in households. Now when we know the problem and understand

Architecture always had a great significance in tourism. Admiring, understanding and learning about architecture as a part of education later became a trend in tourism. In the past decade, a new trend has been noticed that large number of tourists are attracted not only to the old architecture sites, but to the new architectural hotspots which was triggered after opening of Gehry’s Guggenheim Muse
