Blue light was generated at room temperature by quasiphase-matched second harmonic generation in planar and channel lithium tantalate (LiTaO3) annealed proton exchange waveguides using the d33 nonlinear coefficient. Alternating ferroelectric domains for third order quasiphase matching were created by poling the substrates with a periodic electric field.
This paper studies the innovative performance of 130 Swedish corporations during 1993-1994. The number of patents per corporation is explained as a function of the accessibility to internal and external knowledge sources of each corporation. A coherent way of handling accessibility measures, within and between corporations located across regions, is introduced. We examine the relative importance o
Report from the 18th European Conference on Modern South Asian Studies in Lund 6–9 July 2004 arranged by SASNET - Swedish South Asian Studies Network at Lund University.
Chronic itch is a common and distressing symptom that arises from a variety of skin conditions and systemic diseases. Despite this, there is no clinically based classification of pruritic diseases to assist in the diagnosis and cost-effective medical care of patients with pruritus. The proposed classification focuses on clinical signs and distinguishes between diseases with and without primary or
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
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 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
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
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 tillgångarnaEvery 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 peri
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
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
This article has the aim to provide a methodological framework for the calculation of ecological footprints related to leisure tourism. Based on the example of the Seychelles, it reveals the statistical obstacles that have to be overcome in the calculation process and discusses the strengths and weaknesses of such an approach. As many tropical island-states depend heavily on foreign exchange earni
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
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
