Nanocomposite membranes based on poly-(ethylene-co-vinyl acetate) copolymer (18% vinyl acetate content)and two different organomodified clays have been prepared by mechanical mixing using two roll mill method. The morphology of the nanocomposites was investigated using small angle X-ray scattering, scanning electron microscopy, and transmission electron microscopy. The mechanical and thermal studi
Multiple genetic loci confer susceptibility to breast and ovarian cancers. We have previously developed a model (BOADICEA) under which susceptibility to breast cancer is explained by mutations in BRCA1 and BRCA2, as well as by the joint multiplicative effects of many genes ( polygenic component). We have now updated BOADICEA using additional family data from two UK population-based studies of brea
To find out how the ‘generic person’ is expressed in English and Swedish, the use and correspondence of the generic pronouns one in English and man in Swedish are examined in a bidirectional English-Swedish translation corpus. The material demonstrates clearly the greater frequency and versatility of Swedish man and the restricted use of English one. The difference is partly register-related: whil
STUDY DESIGN: By using roentgen stereophotogrammetric analysis in six patients having tantalum indicators implanted at a preoperative external fixation test, the mobility in the spondylolytic lumbosacral level and its adjacent segment could be studied before fusion and during the course of postoperative fusion consolidation. OBJECTIVE: To study the mobility effects on the segment adjacent to a lum
The article presents an analysis of the status of Swedish in relation to the use of English in Sweden and gives some examples to show that Swedish as a national language is losing some functional domains to English. Based on basic democracy principles and the need for effective communication some arguments are given for a national policy to guarantee the status of Swedish and how such a policy cou
In colostrum collected 0-80 h postpartum the contents of immunoglobulins (Igs), transforming growth factor beta-2 (TGF-beta2), insulin-like growth factor-1 (IGF-1) and growth hormone (GH) were analysed. Colostrum initially contained 90 mg mL(-1) IgG1, 2.8 mg mL(-1) IgG2, 1.6 mg mL(-1) IgA, 4.5 mg mL(-1) IgM, and these concentrations declined by 92%, 87%, 93% and 84%, respectively, in the samples c
Many phytoplankton species produce resting cysts, forming 'seed banks' on lake sediments until they germinate and provide inocula (recruitment) for future pelagic populations. We have addressed the question of whether the littoral or the profundal zone provides the inoculum for planktonic populations in a eutrophic and dimictic lake (Lake Erken, Sweden). Our hypotheses were that high temperature,
Culture filtrates of the nematophagous fungi Verticillium chlamydosporium and V. suchlasporium growing on colloidal chitin showed increasing chitinolytic activity and production of two (32- and 43-kDa) main proteins. Maximum activity was found 18-20 days after inoculation, but V. suchlasporium always displayed higher activity. Zymography of such filtrates on carboxymethyl-chitin-Remazol brilliant
Popular AbstractDen snabba folkökningen I Afrika söder om Sahara förändrar kontinuerligt betingelserna för bondebefolkningens försörjning. I ett av de bördigaste och samtidigt mest tättbefolkade områdena I Östafrika, Mount Meru I norra Tanzania, så har befolkningen nära tiodubblats under loppet av de senaste hundra åren. För bönderna i området är markbristen det allt överskuggande problemet. Till Sustained high population growth rates are radically altering the livelihood conditions for small farmers in sub-Saharan Africa. In one of the most fertile and densely settled areas of East Africa, Mount Meru in Northern Tanzania, the size of the population has increased nearly tenfold within the last century. As a consequence, the most serious problem facing farm families is shortage of land. Cou
There is convincing evidence for a decreased risk of breast cancer with increased physical activity. Uncertainties remain, however, about the role of different types of physical activity on breast cancer risk and the potential effect modification for these associations. We used data from 218,169 premenopausal and postmenopausal women from nine European countries, ages 20 to 80 years at study entry
Popular Abstract in Swedish Att packa ryggsäcken och resa till tropikerna, till vad man ofta kallar ‘tredje världen’ för en längre tids vistelse anses ofta vara av avsevärd betydelse för en individs identitet och framtida liv. För många resenärer upplevs resan som ett sätt att ta kontroll över den egna tiden och rörelsen, en kontroll som betraktas som en bristvara i de miljöer resenärerna kommer fThis work addresses the phenomenon of long-term, so-called ‘independent’ travelling, or backpacking, often to destinations described as the ‘third world’. It regards backpacker journeys as arenas for identity work, for expressing individuality and a ‘strong character’. Rather than merely being a parenthetic detour in time and space a backpacker’s trip to the tropics can be understood as a creative
We constructed hydrodynamical model atmospheres for mid M-type main-,as well as pre-main-sequence (PMS) objects. Despite the complex chemistry encountered in these cool atmospheres a reasonably accurate representation of the radiative transfer is possible, even in the context of time-dependent and three-dimensional models. The models provide detailed information about the morphology of M-type gran
Popular Abstract in Swedish Cystatiner är endogena proteasinhibitorer som reglerar den proteolytiska aktiviteten hos papainlika cysteinproteaser, så som humant cathepsin B, H, K, L och S. Cystatin C, som finns i de flesta humana vävnader och vävnadsvätskor, är den starkaste hämmaren av lysosomala cysteinproteaser. Förändring i balansen mellan cysteinproteaser och cystatiner har vid flera olika canCystatins are endogenous protease inhibitors that regulate the proteolytic activities of family C1 (papain-like) cysteine proteases, such as human cathepsins B, H, K, L, and S. Cystatin C shows the fastest inhibition and the highest affinity of all cystatins towards lysosomal cysteine proteases in general and is widespread in human tissues and body fluids. Alterations in the balance between the cy
Three new species, i.e. Hieracium evae I Tyler, Hieracium jonsbergense T. Tyler, Hieracium subnitidum Dahlst. ex T. Tyler, and one variety, i.e. H. ravidum Brenn. var. exaltifrons T. Tyler var. nov. are described. Hieracium myrtillinum (Johanss. ex Dahlst.) T. Tyler comb. nova is proposed. All are based on material collected in the SE Swedish provinces Gotland and Ostergotland.
The influence of the latex surface chemistry on the association of latices with different cellulose derivatives has been investigated by means of isothermal calorimetry and electrophoresis. The chemistries of three grades of coating latices differed with regard to the type and amount of vinylic monomer and the level of carboxylation. In addition, a styrene/butadiene latex substantially free from s
