Numerisk simulering av detektionsmiljö med fältmodeller

För att kunna beräkna tiden till aktivering av en rökdetektor krävs en beskrivning av strömnings- och temperaturförhallandena samt röktätheten i detektorns omgivning. Den transienta utvecklingen av strömnings-, temperatur- och koncentrationsförhållandena i ett rum med en brandkälla och av godtycklig geometri kan simuleras med hjälp av sk fältmodeller. I denna rapport presenteras resultaten fran en

The interaction between PEO-PPO-PEO triblock copolymers and ionic surfactants in aqueous solution studied using light scattering and calorimetry

Properties of nonionic triblock copolymers of poly(ethylene oxide) (PEO) and poly(propylene oxide) (PPO) (EOnPOmEOn) in aqueous solution and their interaction with the ionic surfactants sodium dodecyl sulfate and hexadecyltrimethylammonium chloride have been investigated by static and dynamic light scattering, high sensitivity differential scanning, and isothermal titration calorimetry. The studie

Police Persuasion: Making Battered Women File a Complaint

A common theme in sociological literature on "domestic violence" is that police officers view such cases as private problems and not as objects for proper policework. Thus, it is argued that police officers interactionally discourage arrest in domestic disturbance cases. In an etnographic study of Swedish police officers, however, police officers, instead of discouraging arrest or filing of compl

Abnormal retinal vascular morphology in young adults following intrauterine growth restriction

Objective. Intrauterine growth restriction ( IUGR) resulting in low birth weight for gestational age may predispose one to development of cardiovascular disease later in life. Abnormal fetal blood flow in the presence of fetal growth restriction helps to distinguish infants with true fetal growth impairment from small but normal infants. Our goal was to investigate associations between IUGR with a

Osmotic-treatment-induced cell death and osmotic processing kinetics of apples with characterised raw material properties

Three apple varieties cultivated in southern Sweden namely Jonagold, Kim and Mutsu were subjected to osmotic treatment at 5, 20 and 40 degreesC with a 50% sucrose solution. The evaluation of cell viability after osmotic processing, was carried out in Granny Smith apples from Argentina. The processing conditions were 50% sucrose solution at 20 degreesC and the viability assay used was based on the

Signs of nephropathy may occur early in young adults with diabetes despite modern diabetes management: results from the nationwide population-based Diabetes Incidence Study in Sweden (DISS).

OBJECTIVE—To estimate the occurrence of early-onset renal involvement in a nationwide population-based cohort of young adults with diabetes in Sweden and relate the findings to glycemic control, type of diabetes, sex, smoking, and blood pressure. RESEARCH DESIGN AND METHODS—The Diabetes Incidence Study in Sweden aims to register all incident cases of diabetes in the age-group 15–34 years. In 1987

Moderate hemolytic disease of the newborn (HDN) due to anti-Rh17 produced by a black female with an e variant phenotype

The Rh blood group antigen e is of high incidence and has many epitopes. Partial expression may occur, more commonly in black persons. Individuals with e variant phenotypes can make antibodies to epitopes they lack. While some of these antibodies may be specific for an antigen, e.g., hrB, others, like anti-Rh17 (anti-Hro), show broader specificity, compatible only with D-- and Rhnull red blood cel

A meroterpenoid NF-kappa B inhibitor and drimane sesquiterpenoids from asafetida

Investigation of an acetone extract from asafetida afforded two drimane sesquiterpene dienones (fetidones A and B, 1a,b) and several known sesquiterpene coumarin ethers, one of which (8-acetoxy-5-hydroxyumbelliprenin, 2a) showed potent and specific NF-kappa B-inhibiting properties. This, coupled to a negligible cytotoxicity, qualifies 2a as a new anti-inflammatory chemotype, and its occurrence in
