DSC studies of retrogradation and amylose-lipid complex transition taking place in gamma irradiated wheat starch

The effect of gamma irradiation (60Co) with doses of 5–30 kGy on the amylose–lipid complex transition and retrogradation occurring in gels containing ca. 50% and ca. 20% wheat starch was studied by differential scanning calorimetry (DSC) during heating–cooling–heating cycles (up to three cycles). Transition of the amylose–lipid complex occurs in all the irradiated samples at a lower temperature as

Scaling of migration and the annual cycle of birds

In a seasonally fluctuating environment migratory birds face decisions relating to how to schedule their main life-history activities, i.e. breeding, moult and migration. The time required to complete any one of these depends on overall size. In this paper I derive scaling functions about how time required for breeding, moult and migration depends on body mass. The sum of these increases with incr

A study of the permeability of pulp and paper

A sheet of paper is modelled as a two-dimensional network of cellulose fibres. The fibres are assumed to be either cylindrical or band-shaped. Both well-ordered fibrous structures and fibrous structures in which a random arrangement of fibres is assumed are studied. The equations for creeping flow through such structures are solved, and the calculated permeabilities are compared with measured valu

Antithymocyte globulin and cyclosporine A as combination therapy for low-risk non-sideroblastic myelodysplastic syndromes

The present study evaluated the combination of antithymocyte globulin (ATG) and cyclosporine A (CsA) in patients with low-risk myelodysplastic syndromes. Twenty patients (17 with refractory anemia and 3 with refractory anemia with excess blasts) received treatment with rabbit-ATG plus CsA. The overall response rate was 30% (6/20); three of the six responders had a complete response. The responses

Redovisning av goodwill : utveckling av metoder i Storbritannien, Tyskland och USA

Popular Abstract in Swedish Avhandlingens titel är ju "Redovisning av goodwill". Därför kan det vara lämpligt att fråga sig vad de orden betyder i detta sammanhang. Goodwill har här inte den vanliga betydelsen av det goda anseende som exempelvis ett företag åtnjuter. Det är istället en benämning på skillnaden mellan värdet på hela företaget och summan av värdena på de enskilda tillgångarna minskaEvery conceivable manner of accounting, in the same country, at the same time! This is how-with no great exaggeration-the accounting of goodwill in Sweden in the late 1980s might well be described. Many companies still followed the Accounting Act, amortizing their goodwill over no more than ten years. Some, however, referred to the rules in the United States, extending the amortization period to f

Samarbetskommittén för socionomutbildning 25 år. En kortfattad historik 1977-2002

In 1977 there was a radical reform of Swedish universities. According to the reform the six independent schools of social work were incorporated in universities or university colleges. At the same time a new discipline “social work” was established. The independent schools of social work had curricula decided by the government. With the reform this was decentralised. There was a clear risk of gett

Morphological detection of neurogenic muscle disorders: how can statistical methods aid diagnosis?

The light microscopical observation of groups of histochemically similar muscle fibres, referred to as fibre-type grouping, is commonly considered to be evidence of a denervation and reinnervation process affecting the spinal motor neurons or the peripheral nerves. It can be difficult to assess whether such groups have occurred by chance or are due to a slowly progressive pathological process in a

Disproportionally low clearance of macromolecules from the plasma to the peritoneal cavity in a mouse model of peritoneal dialysis (PD).

Background. This study was performed to establish a model for quantitative measurements of a number of basic peritoneal transport parameters, particularly transperitoneal clearances (Cl) of macromolecules, during mouse peritoneal dialysis. Methods. Mice were anaesthetized using 3% isofluorane inhalation anaesthesia. The right jugular vein and the left femoral artery were cannulated for infusion a

Detector environment and detector response : a survey

1. The survey has mainly concentrated on the following items: the false alarm problem, the problem of the fire not being detected due to the fact that pre-fire heating and ventilation dominate flow inside the compartment, a description of detector sensitivity to fire signatures. engineering design methods for the siting of detectors. 2. The statistical as well as practical experience suggests that

Affinity of galectin-8 and its carbohydrate recognition domains for ligands in solution and at the cell surface.

Galectin-8 has two different carbohydrate recognition domains (CRDs), the N-terminal Gal-8N and the C-terminal Gal-8C linked by a peptide, and has various effects on cell adhesion and signaling. To understand the mechanism for these effects further, we compared the binding activities of galectin-8 in solution with its binding and activation of cells. We used glycan array analysis to broaden the sp

Linear Optimal Prediction and Innovations Representations of Hidden Markov Models

The topic of this paper is linear optimal prediction of hidden Markov models (HMMs) and innovations representations of HMMs. Our interest in these topics primarily arise from subspace estimation methods, which are intrinsically linked to such representations. For HMMs, derivation of innovations representations is complicated by non-minimality of the corresponding state space representations, and r

Photochemical mineralization of dissolved organic carbon in lakes of differing pH and humic content

Photochemical mineralization of dissolved organic carbon (DOC) to dissolved inorganic carbon (DIC) was studied in surface water from 10 oligotrophic lakes in Southern Sweden differing in DOC, pH, and iron content. In addition, we studied the effects of acidification on the DOC photoreactivity. Samples from each lake were filtered through 0.2 mum-filters, acidified by one pH unit or kept under ambi

Gestures in spatial descriptions

Most studies of gesture production to date have been based on analyses of narrative discourse in face-to-face interaction. Issues such as the relationship between gesture types and the content of speech, as well as the distribution of particular gesture types across given narrative sequences have been investigated. Depictive gestures, e.g., are frequent where the content concerns the description o

Lifetimes of triaxial superdeformed states in Lu-163 and Lu-164

Lifetimes of states in the yrast superdeformed bands of Lu-163 and Lu-164 were determined in a Doppler-shift attenuation-method experiment. From fractional Doppler shifts and line shapes, average transition quadrupole moments, Q(t) = 8.2(-0.6)(+1.0) b and 7.1(-0.6)(+0.5) 1), were deduced for one of the bands in Lu-163 OX -0.6 and Lu-164, respectively. These values are much larger than the quadrupo
