The search for planets around white dwarf stars, and evidence for dynamical instability around them in the form of atmospheric pollution and circumstellar disks, raises questions about the nature of planetary systems that can survive the vicissitudes of the asymptotic giant branch (AGB). We study the competing effects, on planets at several AU from the star, of strong tidal forces arising from the
Abstract in UndeterminedPollutants in the air can be in gaseous and particle (solid and liquid) phases. Interactions between these phases occur. The components are emitted to the air by different source mechanisms such as evaporation, disintegration of bulk material and chemical reactions. The significance of different transport mechanisms is, for airborne particles, dependent on the aerodynamic p
Issues of sustainable agriculture have much relevance and urgency for the sustainable production of non-eatable products that have an agricultural origin, such as biofuels. In the chapter the opinion is expressed that joint legal regulations on sustainable use of natural resources and sustainable farming methods for eatable and non-eatable products of an agricultural origin can be an efficient sol
A genetic algorithm for optimal placement of optical fibers in arbitrary geometries for interstitial photodynamic therapy has been developed. Based on calculated fiber positions, the diffuse light distribution is simulated by solving the diffusion equation by means of the finite element method and the treatment time is calculated. Utilizing an instrument for interstitial photodynamic therapy that
We have examined the importance of the actin-based molecular motor myosin 5a for insulin granule transport and insulin secretion. Expression of myosin 5a was downregulated in clonal INS-1E cells using RNAinterference. Stimulated hormone secretion was reduced by 46% and single-cell exocytosis, measured by capacitance recordings, was inhibited by 42% after silencing. Silencing of Slac-2c/MYRIP, whic
The diagnosis of pulmonary tuberculosis (TB) relies on the bacteriological examination of sputum. However, microscopy of smears made directly from sputum has a low sensitivity and there is an urgent need for improved methods. We have compared microscopy of smears made directly from sputum with microscopy after liquefaction of sputum with household bleach (NaOCl) and concentration of bacteria by ce
Protein D is a surface-exposed lipoprotein of the gram-negative bacterium Haemophilus influenzae with affinity for human immunoglobulin D myeloma protein. The gene encoding protein D (hpd) in a serotype b strain of H. influenzae was cloned. Escherichia coli carrying the hpd gene bound human myeloma immunoglobulin D. Nucleotide sequence analysis identified an 1,092-bp open reading frame that was mo
Popular Abstract in Swedish Komplementsystemet ingår i vårt naturliga immunförsvar och bidrar till det förvärvade immunförsvaret bl. a. genom att aktiveras av specifika antikroppar. Komplementsystemets viktigaste skyddsfunktioner är att försvara oss mot bakteriella infektioner, förhindra uppkomst av autoimmuna sjukdomar genom att eliminera immunkomplex och döende celler samt att fungera som en förThe complement system is critically involved in defence against bacterial infection. C2 deficiency is, apart from mannan-binding lectin (MBL) deficiency, the most common homozygous complement deficiency among Caucasians. The classical pathway of complement activation is not functional in C2 deficiency and the condition is associated with invasive infections caused by the encapsulated bacteria Stre
Hemicellulosic materials are among the most abundant renewable resources on earth, but have not yet found any broad application. However, if a cost effective extraction method is developed, hemicelluloses have the potential to be utilized to a much larger extent in the future. Ultrafiltration (UF) is a low energy demanding separation process that can be used to concentrate and purify hemicellulose
OBJECTIVE: To compare 3 immunoassays, an immune complex assay, and an application of the polymerase chain reaction (PCR) for the diagnosis of tuberculous meningitis (TBM). MATERIAL: Cerebrospinal fluid (CSF) from 33 patients with TBM and from 34 control patients with infectious and non-infectious CNS diseases was analysed. RESULTS: The antibody immunoassays were either nonspecific or insensitive.
The number of elderly people is gradually increasing, and with it the number of persons receiving some kind of care in their everyday lives. However, researchers and the mass media recurrently report great difficulties for many caregivers in their work situations. This article considers process-oriented supervision as a pedagogic method for training and support of nurse aids and managers in Swedis
We describe a test which uses the ability of viable cells to reduce 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) to detect resistance to a bactericidal drug, rifampin, in in vitro-cultured Mycobacterium tuberculosis. The assay shows a linear relationship between the number of viable bacteria and the ability to reduce MTT. Dead mycobacteria were unable to reduce MTT. Rifampin
On the basis of two points of departure: (1) no state has clean hands and (2) the types of crime a state commits vary with state formations, this article explores cases where the Swedish state and its agencies have been held responsible for some form of wrongdoing. Drawing on a total of 8,561 judgments issued against the state by agencies of control (the Parliamentary Ombudsman, the Chancellor of
BACKGROUND: The Global Burden of Diseases, Injuries, and Risk Factors Study 2015 provides an up-to-date synthesis of the evidence for risk factor exposure and the attributable burden of disease. By providing national and subnational assessments spanning the past 25 years, this study can inform debates on the importance of addressing risks in context.METHODS: We used the comparative risk assessment
BACKGROUND: Improving survival and extending the longevity of life for all populations requires timely, robust evidence on local mortality levels and trends. The Global Burden of Disease 2015 Study (GBD 2015) provides a comprehensive assessment of all-cause and cause-specific mortality for 249 causes in 195 countries and territories from 1980 to 2015. These results informed an in-depth investigati
