Three-dimensional ultrasound assessment of the cervix for predicting time to spontaneous onset of labor and time to delivery in prolonged pregnancy

Objectives To determine whether three-dimensional (3D) ultrasound including power Doppler examination of the cervix is useful for predicting time to spontaneous onset of labor or time to delivery in prolonged pregnancy. Methods A prospective study was conducted in 60 women who went into spontaneous labor. All underwent transvaginal 3D power Doppler ultrasound examination of the cervix immediately

Outcome after endovascular treatment of Hunt and Hess grade IV or V aneurysms: comparison of anterior versus posterior circulation

BACKGROUND AND PURPOSE: The most common cause of poor treatment outcome in patients suffering aneurysmal subarachnoid hemorrhage is cerebral vasospasm, especially in cases of poor Hunt and Hess grades (IV and V). A further prognostic factor in surgically treated patients is aneurysm localization. The aim of the present retrospective study is to compare the endovascular treatment outcome in such po

Chronopharmacologic aspects of hexobarbital oxidation rate in rats

Circadian variations of hexobarbital oxidation rate in rat liver and the relationship to serum corticosterone levels were determined in 324 animals subjected to different lighting regimen and feeding schedules.--Rats maintained under standard light/dark conditions and with free access to food showed a significant circadian hexobarbital oxidase rhythmicity. Inversion of the light/dark cycle and tim

Resonant inelastic X-ray scattering at the K edge of oxygen and fluorine in insulators

Here we present the results of a study of the electronic structure using the resonant inelastic scattering process at the F 1s photoabsorption edge in LiF and O 1s edge of MgO crystals. In case of excitations in the sub-threshold region, the Raman-type linear dispersion of X-ray fluorescence peak was observed for the studied compounds. In LiF, the narrowing of the X-ray fluorescence peak is observ

Role of supraspinal alpha 1-adrenoceptors for voiding in conscious rats with and without bladder outlet obstruction

Purpose: Previous studies have shown that spinal alpha1-adrenoceptors can influence voiding in normal rats and in rats with outlet obstruction. Also, at the supraspinal level such receptors may be involved in voiding control. Therefore, we studied in rats the effects on cystometrography of intracerebroventricular administered alpha1-adrenoceptor antagonists. Materials and Methods: Continuous cysto

Energy flow and rapidity gaps between jets in photoproduction at HERA

Dijet events in photon-proton collisions in which there is a large pseudorapidity separation, Deltaeta > 2.5 between the two highest E-T jets are studied with the H1 detector at HERA. The inclusive dijet cross sections are measured as functions of the longitudinal momentum fractions of the proton and photon which participate in the production of the jets, x(p)(jets) and x(gamma)(jets) respectively

Ungdomars spel om pengar : Spelmarknaden, situationen och karriären

Popular Abstract in Swedish Spel om pengar har blivit ett utbrett fenomen i Sverige under 1990-talet, med spelbutiker, spelhörnor i varuhusen, spelmaskiner och spel med kort och på roulette på pubar, pizzerior och restauranger, samt spel på Bingo-Lotto hemma i vardagsrummet. Förutom den ökade tillgången till legala spelformer blir det allt vanligare med spel i miljöer och sammanhang där det inte fGambling has become widely accepted in Sweden during the 1990s, with betting shops, gambling machines and casino-like gambling in pubs and restaurants, as well as Bingo-Lotto in our living rooms. Beyond the expansion in availability of legal gambling opportunities, the most notable change is the shift from gambling in specific venues to gambling in a much wider range of social settings. The conseq

THEORY OF RESONANT EMISSION PROCESSES IN METALS

A simple and transparent formalism is presented to treat emission processes in general and resonant emission processes in metals in particular. As an example resonant photoemission in Cu metal is discussed.

Overload control strategies for distributed communication networks

In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. The services may also have different priorities and quality of service requirements.

Crystal structure of the Escherichia coli dUTPase in complex with a substrate analogue (dUDP)

We have determined the structure of the homotrimeric dUTPase from Escherichia coli, complexed with an inhibitor and substrate analogue, dUDP. Three molecules of dUDP are found symmetrically bound per trimer, each in a shallow cleft between adjacent subunits, interacting with evolutionary conserved residues. The interactions of the uracil ring and the deoxypentose with the protein are consistent wi

Tingens och tankarnas landskap : försök i naturumgängets arkeologi med exempel ur Blekinges och Smålands förflutna

Popular Abstract in Swedish Avhandlingen ”Tingens och tankarnas landskap” söker arkeologiska metoder och teorier för ett humanistiskt närmande av människans tidiga naturumgänge. Med arkeologiskt menas här fokuseringen på de materiella spåren i landskapet, stora som små, naturdanade som människotillverkade. Tidsperspektivet är i huvudsak långtida. I avhandlingen har jag valt ett ekologiskt perspektThe thesis "Tingens och tankarnas landskap" is about the material traces of man and his activities in the past. The study investigates the possibility and methods of describing man’s interaction with nature. Man’s relationship to the physical surroundings is viewed from cultural and social perspectives, using the materials of long-term archaeology. The study also includes a contemporary dimension.

Thin graphite overlayers: Graphene and alkali metal intercalation

Using LEED and angle resolved photoemission for characterisation we have prepared graphite overlayers with down to monolayer thickness by heating SiC crystals and monitored alkali metal intercalation for the multilayer films. The valence band structure of the monolayer is similar to that calculated for graphene though downshifted by around 0.8 eV and with a small gap at the zone corner. The shift

Overall and health related quality of life among the oldest old in pain.

Objectives: To compare the oldest old (85 years and above) in pain with those with no pain across gender, regarding demographic data, living conditions, social network/support, walking/mobility problems, fatigue, sleeping problems, depressed mood and quality of life (QoL). The aim was also to test how these variables were related to QoL among the oldest old in pain. Methods: The study comprised 16
