This study was performed to elucidate circulatory changes in the fetal cerebral circulation during uncomplicated labor and in early neonatal life. Eighteen healthy term singleton fetuses were followed longitudinally during labor. Using the transabdominal approach, and the color Doppler technique, the middle cerebral artery was identified and Doppler flow velocity waveforms recorded between and dur

The aim of the study was to identify mechanisms acting at internal frost destruction of concrete. By 'internal frost destruction' is meant damage caused inside concrete that is moisture insulated from the surroundings, i.e. when no moisture exchange with the surroundings is possible during freeze-thaw. Thus, the aim was not to investigate destruction processes (scaling) taking place at the surface

Popular Abstract in Swedish Varför lyckas EU-länderna allt oftare agera gemensamt i frågor som rör internationell fred och säkerhet? Genom att först visa hur volymen och innehållet i Unionens gemensamma utrikes- och säkerhetspolitik har expanderat sedan 1970, närmar sig denna studie ovanstående fråga från tre olika vinklar: Är det först och främst gradvisa institutionella förändringar som möjliggjIt is difficult for states to cooperate on issues related to international peace and security. Yet, ever since 1970, the EU member states have succeeded to gradually intensify their foreign policy cooperation and increasingly act in unison towards the rest of the world. This PhD thesis seeks an explanation to this trend. It does so by initially painting a picture of when, in time, the volume and c

During normal cooking of meat, a class of mutagenic/carcinogenic compounds called heterocyclic amines is formed. Heterocyclic amines are rapidly absorbed and metabolised in the human body, and for estimation of the intake of heterocyclic amines, it is useful to determinate their levels in the urine. Blue Chitin columns were used for the extraction and purification of heterocyclic amines from urine

Genetic modification leads to several important moral issues. Up until now they have mainly been discussed from the viewpoint that only individual living beings, above all animals, are morally considerable. The standpoint that also collective entities such as species belong to the moral sphere have seldom been taken into account in a more thorough way, although it is advocated by several important

Synthesis of the title compounds in four steps using inexpensive collidine and lutidine as starting materials is described.

In this summary I briefly discuss some of the many interesting talks presented at this symposium.

Background. Antibiotic utilisation varies profoundly among and within countries, and the extent of antibiotic utilisation correlates with the frequency of bacterial resistance, particularly among children. Hence, it is important to assess which factors may influence prescribing. In addition to variations in morbidity, health-care organisation, drug regulatory and supply systems, prescriber's attit

This paper describes the application and evaluation of a competitive enzyme flow injection immunoassay (EFIIA) for screening of alkylphenol ethoxylate (APEO) surfactants in different water samples based on a generic immunoassay system previously developed ( see E. Burestedt, C Nistor, U. Schagerlof and J. Emneus, Anal. Chem., 2000, 72, 4171 - 4177). The detection limits for octylphenol ethoxylates

BACKGROUND: Diagnosis and management of intrauterine growth retardation during pregnancy remain a major challenge in obstetric care. The objective of this survey was to evaluate the routine clinical management of pregnancies with suspected intrauterine growth retardation at obstetric departments in Sweden. METHODS: In 1997, a questionnaire was sent to all 59 obstetric departments in Sweden. Forty-

Intervju med filmregissören Oliver Stone.

We review some work done by us calculating matrix elements for Kaons. Emphasis is put on the matrix elements which are relevant to predict non-leptonic Kaon CP violating observables. In particular, we recall our results for the (B) over cap (K) parameter which governs the (K-0) over bar - K-0 mixing and update our results for epsilon(K)' including estimated all-higher-order CHPT corrections and th

Semenogelins I and II are the quantitatively dominating proteins in human semen. They comprise the major part of the sperm-entrapping gel formed at ejaculation, which subsequently liquefies due to proteolysis of the gel-forming proteins by prostate-specific antigen (PSA). The mechanism behind gel formation and its physiological significance is not known. We have studied phosphorylation and dephosp

Popular Abstract in Swedish Denna avhandling behandlar analys och förbättringar av en metod att mäta blödgenomströmning i vävnad med kontinuerlig ultraljudsdoppler. Tidigare har stora variationer i detekterat perfusionsvärde observerats som en effekt av speckle, eller våginterferens. Här presenteras en teoretisk modell som förklarar specklefenomenet i en sådan mätsituation. Modellen förutsäger deThis thesis has the main focus on ways to improve the blood perfusion estimate, as obtained from a continuous wave Doppler system. Earlier studies have shown large temporal variations in the detected perfusion estimate, due to speckle. Here, a theoretical model to predict frequency dependent characteristics of speckle in continuous wave ultrasound is presented. The model predicts the frequency shi
