Popular Abstract in Swedish Polymerer och tensider är molekyler vi stöter på i vårt vardagliga liv, när vi bär hem våra matvaror i plastkassar, tvättar håret, målar huset eller tar en värktablett. Klassificeringen polymer är väldigt bred och innefattar allt från naturliga polymerer som cellulosa, till syntetiska polymerer som polystyren. Polymerer består av små, repeterande enheter, kallade monomeComplexes formed between oppositely charged polyions and surfactant ions are known to have very rich phase behaviour in bulk solution. The work in this thesis investigates the possibilites of using such complexes as surface coatings. Stoichiometric polyion-surfactant ion complexes “complex salts” (CS) consisting of alkyltrimethylammonium surfactant ions and polyacrylates are typically insoluble i

Popular Abstract in Swedish Antagonistiska hot mot godstransporter och logistik såsom stölder, smuggling, förfalskningar och terroristaktiviteter utgör ett stort och ofta förbisett problem. Bara i Sverige beräknas stölder under transport kosta samhället ca 1 miljard kronor årligen. Denna avhandling visar att många svenska transportföretag trots detta inte investerar i lösningar för att förbättra sThe objective of this study is to understand what factors influence the security of physical distribution networks. Thereafter it aims to bring to light what security measures exist today to enhance security and finally how to determine the profitability of security investments.
Eight stakeholders affecting security in physical distribution networks are identified and combined into a Physical

Abstract OBJECTIVES: To investigate the effects of antenatal betamethasone on fetal and uteroplacental hemodynamics. METHODS: The study comprised 33 women with singleton high-risk pregnancies (23-33 weeks; 27 pregnancies < 30 weeks) not in labor, but at risk for preterm delivery based on fetal or maternal indications. They were treated with two doses of 12 mg betamethasone intramuscularly 24 h ap

OBJECTIVE.: Finding of venous congestion at histopathological examination of placenta indicates the importance of abnormal placenta-maternal venous return. The present descriptive study investigates the possibility of recording Doppler flow signals from maternal uterine veins. MATERIAL AND METHODS.: Transabdominal Doppler ultrasound examinations of uterine veins on both sides of uterus were perfor

Designed as a system which, by transfer of knowledge and extended documentation, can act as one of many tools when it comes to dealing with situations containing violence, the SVARNE system may turn out to be an useful aid not only for people working with
