A detailed analysis of 2 years' hourly microclimatic (mainly surface air temperature) data recently acquired from locations widely dispersed over 700 km2 in the Abisko catchment encompassing Lake Tornetrask in Swedish Lapland is presented in this study. This project is designed to explore the effects of microclimatic variability, past and future climate change (1913-2100) on regional vegetation an
The influence of salts (NaCl, NaBr, and NaI) on the formation of mesoporous silica SBA-15 was studied in situ by small-angle X-ray scattering and diffraction. Pluronic P104 was used as structure director. The micellar properties and the dynamics of formation were clearly dependent on the presence of salt. It was also shown that the kinetics of mesophase formation, the initial value of the cell par
Current European Society for Vascular Surgery guidelines recommend that patients with a symptomatic carotid stenosis should be operated on within 14 days of onset of symptoms. Recent reports indicate that carotid endarterectomy (CEA) within 2 days of a neurological event may be associated with a higher peri-procedural risk of stroke. Whether urgent carotid artery stenting (CAS) carries a similar h
Background/Objectives:Diets high in saturated and trans fat and low in unsaturated fat may increase type 2 diabetes (T2D) risk, but studies on foods high in fat per unit weight are sparse. We assessed whether the intake of vegetable oil, butter, margarine, nuts and seeds and cakes and cookies is related to incident T2D.Subjects/Methods:A case-cohort study was conducted, nested within eight countri
In breast tomosynthesis1 (BT) a number of 2D projection images are acquired from different angles along a limited arc. The imaged breast volume is reconstructed from the projection images, providing 3D information. The purpose of the study was to investigate and optimize different reconstruction methods for BT in terms of image quality using human observers viewing clinical cases. Sixty-six cases
The problem of partitioning an input rectilinear polyhedron P into a minimum number of 3D rectangles is known to be NP-hard. We first develop a 4-approximation algorithm for the special case in which P is a 3D histogram. It runs in O(m log m) time, where m is the number of corners in P. We then apply it to compute the arithmetic matrix product of two n x n matrices A and B with nonnegative integer
SU-8 is the preferred photoresist for development and fabrication of high aspect ratio (HAR) three dimensional patterns. However, processing of SU-8 is a challenging task, especially when the film thickness as well as the aspect ratio is increasing and the size of the features is close to the resolution limit of photolithography. This paper describes process optimization for the fabrication of den
A structural affinity between republican freedom as non-domination and human rights claims accounts for the relevance of republicanism for cosmopolitan concerns. Central features of republican freedom is its institution dependence and the modal aspect it adds to being free. Its chief concern is not constraint, but the way in which an agent is constrained or not. To the extent I am vulnerable to so
In this work we have used simple microfabrication techniques and chemical de-alloying of co-sputtered AgAu alloys to create nanoporous gold (np-Au) electrodes. The physical properties of the np-Au electrodes were investigated using scanning electron microscopy with energy dispersive X-ray analysis, X-ray photo-electron spectroscopy and profilometer. The electrochemical performance of the np-Au ele
P>Lilja M. School attainment of children who had a single umbilical artery at birth. Paediatric and Perinatal Epidemiology 2010; 24: 166-170. To the best of our knowledge, this is the first registry study of school achievements among children born with a single umbilical artery (SUA). A total of 1600 infants born with SUA during 1983-86 were studied. We linked the Swedish Medical Birth Registry wi
We present the first measurement of elliptic (v(2)) and triangular (v(3)) flow in high-multiplicity He-3 + Au collisions at root s(NN) = 200 GeV. Two-particle correlations, where the particles have a large separation in pseudorapidity, are compared in He-3 + Au and in p + p collisions and indicate that collective effects dominate the second and third Fourier components for the correlations observe
Background: Little is known of the association between thyroid hormones in the central nervous system and Alzheimer's disease (AD). We determined thyroid hormone levels in serum and cerebrospinal fluid (CSF) in a well-defined homogeneous mono-center population. Methods: Fifty-nine consecutive patients under primary evaluation for cognitive impairment were recruited. The participants included patie
Cloud condensation nuclei counter (CCNC) measurements performed at 14 locations around the world within the European Integrated project on Aerosol Cloud Climate and Air Quality interactions (EUCAARI) framework have been analysed and discussed with respect to the cloud condensation nuclei (CCN) activation and hygroscopic properties of the atmospheric aerosol. The annual mean ratio of activated clou
How do females decide which males to accept or reject as potential mates when the individuals encountered are unfamiliar and may be either heterospecifics or conspecifics? Learning often influences the development of mate preferences. Experience with particular phenotypes often positively biases preference for that phenotype. However, experience can also induce aversion. We studied the effect of s
To explore changes in performance in daily activities (self-care and mobility) 10 years after selective dorsal rhizotomy (SDR).
We discovered a symbiotic lactic acid bacterial (LAB) microbiota in the honey stomach of the honeybee Apis mellifera. The microbiota was composed of several phylotypes of Bifidobacterium and Lactobacillus. 16S ribosomal ribonucleic acid (rRNA) gene analyses and phenotypic and genetic characteristics revealed that the Lactobacillus phylotypes isolated represent seven novel species. One is grouped w
Despite the popularity of the social investment approach, there remain ambiguities regarding how to design an effective social investment policy. We review evaluations of conditional cash transfers (CCTs) in Latin America in order to draw out lessons for how to improve the effectiveness of social investment. CCTs share many of the objectives of the social investment approach and are targeted at po
