Copolymers of 1,5-dioxepan-2-one (DXO) and L- or D,L-dilactide have been synthesized and characterized. The molar ratio of the two monomers was around 20/80 of DXO and L- or D,L-lactide respectively. In vivo studies on rats revealed significant differences in tissue response between the semicrystalline DXO/L-LA copolymer and the amorphous DXO/D,L-LA copolymer. The materials were characterized pre-

The relationship between economic development and environmental quality is a debated topic. Environmental Kuznets curve (EKC) is one prominent hypothesis, positing an inverted U-shaped development-environment relationship. Here we test this hypothesis using data from Shenzhen, People's Republic of China. Established in 1980 as the first special economic zone in China, Shenzhen has developed from a

Direct microcalorimetry was used for measurements of heat production in cell suspensions of platelets and adipocytes, obtained from hypothyroid patients before and after 3 months on full L-thyroxine substitution. Platelet heat production was significantly lower than normal before treatment and increased in all 10 patients studied; the mean value increased from 51.3 +/- 1.6 fW/cell before to 57.1 +

The authors' intention is to show that there are other criteria when optimising digital filters than minimising the filter order. The final result in the form of minimum silicon area or few machine cycles in a high-speed custom DSP are aims that are important in a custom design process. It is not an axiom that the minimum order of the filter gives the optimum result. Algorithms with trivial coeffi

BACKGROUND. Recurrence rates after surgical repair of groin hernia vary between 3% and 20%. One possible reason for recurrent hernias are ipsilateral multiple hernias, which might have been overlooked at the primary operation. METHODS. In the present series 1010 patients with unclear groin pain underwent herniography. RESULTS. A total of 314 patients had hernias, and seventy-one (23%) of these had

We propose a method to improve the diagnosis of infection in the paranasal sinuses, distinguishing between mucous and serous cases. The method utilizes a previously published method whereby the viscosity in a sealed container may be measured using an ultrasound Doppler method. As ultrasound propagates in a liquid medium, due to attenuation, the resulting pressure gradient will cause the liquid to

The nuclear equation of state (EOS) is probed from statistical parameters, determined in an excitation function experiment on p + Xe-nat reactions at 200-1400 MeV. Total charge (Z) distributions follow a cascade-[multi]fragmentation-evaporation (CFEM) model well. The caloric curve in regions supposedly dominated by fast processes is compatible with a pure statistical multifragmentation (SMM) proce

We here present the clinical phenotype in 6 patients from a family with autosomal dominant retinitis pigmentosa found to carry a point mutation in the rhodopsin gene (arginine-135-tryptophan). The mutation is the second found by mutation screening of DNA from 20 Swedish families with dominant retinitis pigmentosa. With full-field electroretinography we could document a severe form of retinitis pig

The purpose of the book is to be a comparative study of how the aristocracy in Western Europe organised space and landscape, especially inside and adjacent to their residences. This comparison will involve examples from Britain, France, Germany and Scandinavia and is concentrated to the period c. 800-1500. The overall aim is to search after a common aristocratic spatial ideology and to explain its

Objective: To determine the importance of IgM antibodies against phosphorylcholine ( aPC), a novel protective factor for cardiovascular disease ( CVD), in a population with a non-western life style as compared with a Swedish control group. Methods and results: Risk factors for cardiovascular disease were determined in a group of 108 individuals aged 40-86 years from New Guinea and 108 age-and sex-

Popular Abstract in Swedish Under kvartärtiden (de senaste 2,6 miljoner åren) har istider (glacialer) och mellanistider (interglacialer) avlös varandra. Mellanistider är perioder (ca 10 000 år) mellan istider (ca 100 000 år), vilket innebär att istid varit det normala under kvartärtiden och att Holocene, den istid vi nu lever i, endast representerar ett kortare intervall. Under istiderna täckte inThe aim of this thesis was to reconstruct the glaciodynamics, deglacial landforms, isostatic uplift and to date the deglaciation. Glaciodynamics and deglacial landforms were focused on to provide a process and depositional model for De Geer moraine and Niemisel moraine and to reveal their internal and spatial relationship, based on detailed sedimentological and structural investigations.
