The mechanical stress build up in fibre handling, the dynamical frictional phenomena between fibres and curves surfaces and formation of dust have been studied. Typical are stick slip behaviour and threshold stress levels for formation of dust. The emissions of dust can be limited by electrostatic charging. The measured coefficients of friction of the fibres depend on the mechanical properties, mi

Bird brooches at Uppåkra have a changing biography, as grave gifts, pendants, and scrap metal. The association between bird brooches and birds of prey, and a male face to female jewellery opens questions of identy of the wearer and the male person in question. Following the bird brooches and the connotations of falconry decode both a social identiy and a lifestyle, expressed in the aestetics of th

Purpose – The purpose of this paper is to systematically and critically review the extant literature on the design of global production and distribution networks to identify gaps in the literature and identify future research opportunities. The design aspects deal with strategic and structural decisions such as: opening or closing of manufacturing plants or distribution centres, selection of locat

The complex and highly interconnected intercellular air spaces of plant tissues occupied by gas or native liquid has offered the possibility for impregnation with a wide range of compounds. In food processing, the development of vacuum impregnation has allowed a controlled way to introduce these compounds to the tissue structure aiming at modifying structural, nutritional, and/or functional proper

Background and aims. Adverse events (AE) leading to discontinuation or dose-reduction of thiopurine therapy (TP) occur in 9-28% of patients with inflammatory bowel disease. 6-Thioguanine (6-TG) has been proposed as an alternative treatment in patients intolerant for azathioprine (AZA), but some concerns have been raised about drug safety. Methods. We evaluated in a prospective manner the tolerance

The macroscopic appearance and microstructure in the dilute corner of the ternary monoolein (MO)-sodium oleate (NaO)-water ((H2O)-H-2) system have been investigated by visual inspection and by using direct structural imaging with light microscopy and cryogenic transmission electron microscopy. The microstructural transformations that take place between the micellar phase (binary NaO-(H2O)-H-2 axis

Background The alpha-emitter radium-223 (Ra-223) is a bone-seeking radionuclide studied as a new treatment for patients with bone metastases from hormone-refractory prostate cancer. We aimed to study mature outcomes from a randomised, multicentre, phase II study of Ra-223. Methods Patients with hormone-refractory prostate cancer and bone pain needing external-beam radiotherapy were assigned to fou

A REE-bearing fluorosilicate from the Tommot REE-Nb deposit in Yakutia, Russia, described without a name in 1966, is characterized here as a new species, proshchenkoite-(Y), of the vicanite group of borosilicates. Wavelength-dispersive electron probe analyses gave the following empirical formula: (Y3.70REE7.54Ca1.55Na1.16Mn0.77Th0.10Pb0.01)(Sigma 14.83)(Fe0.832+M0.15Ti0.02)(Sigma 1.00)Ca-1.00 (P0.

One goal of animal breeding is to increase the economic output through increased production, improved milk quality, and cow health. The objective of this study was to evaluate genetic progress in relation to milk composition, processability, and yield as a correlated response to selection for the Swedish breeding objective. Dairy cows with high genetic merit, classified as elite dairy cows, of the

A rheological study of mixed micelles formed by PEO-PPO-PEO triblock copolymer P123 and nonionic surfactant C12EO6 in aqueous solutions has been carried out with the purpose of investigating the time dependence of a shape transition of the mixed micelles and characterizing the shape before and after the transition. The rheology results presented in this report give clear evidence that the P123-C12

Biopsy samples of head and neck carcinomas were investigated with regard to elafin, secretory leukocyte protease inhibitor (SLPI), interleukin 1-receptor antagonist [(IL)1-RA] and soluble tumour necrosis factor alpha receptor antagonist (STNFalpha RI). SLPI and elafin are serine protease inhibitors produced in the serous cells of the upper respiratory airways and in the keratinocytes, respectively

In this study the effect of the composite membrane structure on the mass transfer limitations in hydrophobic pervaporation of dilute aqueous solutions of homologous series of alcohols and esters was investigated. Three hydrophobic membranes with poly (octyl)methylsiloxane (POMS) as an active layer were used. The membranes studied varied with respect to the thickness of the active layer and the nat

The effects of varying pan temperature and meat patty diameter on heat (temperature at the centre (5 mm) and 2 mm below the surface) and mass transfer (total, water and fat loss) of beefburgers prepared by double-sided frying were studied, The porosity of the fried beefburgers was determined based on the volume shrinkage and density measurements. The thawing time measured at the centre of the beef

PURPOSE: To evaluate the effect of intraocular pressure (IOP)-reducing treatment on the development of disc hemorrhages in patients with glaucoma. DESIGN: Prospective cohort study of patients in the Early Manifest Glaucoma Trial, followed up to 11 years (median = 8 years). PARTICIPANTS: Patients with newly detected glaucoma randomized to argon laser trabeculoplasty plus betaxolol (n = 129) or no i

More than 50 years ago, Fish postulated that a special form of early abnormal neurodevelopment, "pandysmaturation", defined a priori as constituting retarded cranial development in the first year of life, combined with delay in early motor milestone attainment, was related to genetic risk for schizophrenia, and was associated with schizophrenia-spectrum disorders in young adulthood. Fish confirmed

The applicability of manufacturing planning and control methods differs between environments. This paper explains the fit between the planning environment and material and capacity planning on the detailed material planning and shop floor control levels. The study is based on a conceptual discussion and a survey of 84 Swedish manufacturing companies. Results show the use of planning methods and th
