The blood flow in rat liver was measured with Xe-133. Three techniques for administering the activity to the liver were employed: injection via the portal vein, via the hepatic artery, and directly into the liver parenchyma. Use of intraparenchymal injection of Xe-133 gave 60% higher flow values than by portal or arterial injection techniques. Mean flow index (k1) was for portal injection 0.52, fo
Under mitt dryga år som doktorand i processrätt på juridiska fakulteten vidLunds universitet har frågor om i vilken turordning en domstol ska pröva olika faktapåståenden inom ramen för ett dispositivt tvistemål uppkommit förvånansvärt ofta. Vid diskussioner med domare, advokater och akademiker har åsikterna inte alltid varit samstämmiga och när jag hänvisat till vad vi inom processrätten kallar de
Objective: This study was undertaken to assess whether deviations from normal fetal growth are associated with spontaneous preterm delivery. Study design: A population-based study was performed, using Swedish Medical Birth Register data from 1991 through 2001. The total population comprised 1,007,648 singleton births. Intrauterine-derived growth standards were used to identify individual standard
Neurogenin 2 (Ngn2) is a proneural gene involved in neuronal differentiation and subtype specification in various regions of the nervous system. In the ventral midbrain, Ngn2 is expressed in a spatiotemporal pattern that correlates with the generation of mesencephalic dopaminergic (mesDA) neurons. We show here that lack of Ngn2 impairs the development of mesDA neurons, such that less than half of
An efficient method for increasing the dilution rate of brine water discharged into the sea is an inclined negatively buoyant jet from a single port or a multi-diffuser system. Such jets typically arise when brine is discharged from desalination plants. Two small-scale experimental studies were conducted to investigate the behaviour of a dense jet discharged into lighter ambient water. The first e
En teknik för att förhindra yterosion och samla ytavrinning är bygga jordvallar (1–1,5 m höga) parallellt medhöjdkurvorna. Denna teknik används över stora områden i Tunisien. I denna studie undersöks hur dessa jord-vallar påverkar ytjordens rumsliga variabilitet av markvattenhalt (θ) och salinitet, dels uttryckt som jordenstotala elektriska konduktivitet (σa) och dels som porvattnets elektriska koOne technique for collecting rainwater and prevent soil erosion applied on large areas in Tunisia involves theuse of soil ridges (1–1.5 m high). These contour ridges are constructed parallel to topographical isolines. Theeffects of the contour ridges on the soil water content (θ) distribution, bulk soil salinity σa, and soil water salin-ity (σw) were investigated in the catchment of El-Gouazine in
During recent years, Geographic Information Systems (GIS) as a powerful tool have had a tremendous impact on research techniques in the realm of geography and spatial analysis. The integrative ability of GIS to capture, store, manipulate, analyze, manage, and finally present all types of geographical spatial data, has drawn many attentions to it. Water Resources Engineering as a interdisciplinary
Pulsar binaries are important targets for ground-based and future space-borne gravitational-wave (GW) detectors. In order for improving detector design and assessing detector performances, it is a prerequisite to understand the astrophysics of GW sources such as the population size or merger rates. Here, we summarize recent results for Galactic merger rates of two known types of pulsar binaries: (
Normalt sett föreställer man sig att det finns ett samband mellan ord och handling. Det skulle betyda att människor som säger sig vara miljöengagerade också tar miljöhänsyn i vardagslivets handlingar. Man kan emellertid konstatera att vägen från ord till handling är kantad av många slags överväganden som leder till skillnader mellan det man säger sig tycka och vad man sedan gör. Mellan attityd och
