This article describes the microstructure and dynamics in the solid state of polyfluorene-based polymers, poly(9,9-dioctylfluorenyl-2,7-diyl) (PFO), a semicrystalline polymer, and poly[(9,9-dioctyl-2,7-divinylene-fluorenylene)-alt-co-{2-methoxy-5-(2-ethyl-hexyloxy)-1,4-phenylene vinylene}, a copolymer with mesomorphic phase properties. These structures were determined by wide-angle X-ray scatterin
This paper addresses variations in the wind climate in relation to changes in the impact of wind erosion on agricultural lands with Scania, the southernmost province of Sweden, as an example. The literature concerning wind erosion in the region is reviewed and the conclusions are linked to recent analyses of the regional wind climate. Presently, wind erosion occasionally induces problems in light
We report the first measurement of the near oxygen K-edge auger spectrum of the glycine molecule. Our work employed an x-ray free electron laser as the photon source operated with input photon energies tunable between 527 and 547 eV. Complete electron spectra were recorded at each photon energy in the tuning range, revealing resonant and non-resonant auger structures. Finally ab initio theoretical
Rye bran was added to frankfurter-type sausages and meatballs with the aim of producing low-fat products with increased dietary fibre content. The addition of untreated rye bran to sausages was detrimental, causing a substantial increase in frying loss (20% compared to 13.2%). The addition of rye bran treated with hydrolytic enzymes reduced the frying loss to 15.2-16.4%. The firmness was also impr
BACKGROUND: Accumulating evidence supports a role for the immune system in the pathogenesis of Parkinson's disease. Importantly, recent preclinical studies are now suggesting a specific contribution of inflammation to the α-synuclein-induced pathology seen in this condition.METHODS: We used flow cytometry and western blots to detect toll-like receptor 2 and 4 expression in blood and brain samples
This paper summarizes the results and experiences from the full-scale discfilter plant at the Rya WWTP. In 2010 the WWTP was extended with post-denitrification and a discfilter plant for tertiary filtration of the effluent in order to meet the new discharge limits of 10 mg total nitrogen and 0.3 mg/l of total phosphorus. The disc filters receive effluent from both the moving bed biofilm reactor (M
The increase in structural capacity due to muscle contraction in the lower leg was investigated in osteopenic and normal rats. Osteopenia was induced by ovariectomy combined with a low-calcium diet (0.01%). The control rats were sham operated and fed a diet containing 1.1% calcium. After 7 weeks the right lower leg of all animals were fractured in three-point ventral cantilever bending during musc
Zirconocene precatalysts with sterically bulky alkyl groups were designed as model systems for the propagating species in zirconocene-catalyzed alkene polymerization. Specialty alkyllithium reagents Li(CH2CEt3) and Li(CH2CMe2CH2Ph) were prepared and utilized in the synthesis of dialkyl and methyl-alkyl zirconocenes of the form CpCp*ZrR2, Cp2Zr(CH3)(R), and CpCp*Zr(CH3)(R) (Cp = (5-C5H5); Cp* = (5-
We present a theoretical study of vibrational and thermal effects on the dipole polarizability of methane and carbon tetrachloride. Using a fourth order Taylor expansion in rectilinear normal coordinates of the potential and property surfaces we solve the vibrational problem using vibrational structure theory, e.g., through vibrational self-consistent-field or vibrational configuration-interaction
A "compass rose" pattern sometimes appears when stock returns are plotted against themselves with a one-day lag, since stock prices move in discrete steps. In this paper, we perform a Monte Carlo study on simulated stock price series rounded in different ways to mirror the behavior of stocks on the Stockholm Stock Exchange. We find AR-GARCH parameter estimates to be affected by the discreteness im
Encapsulated Haemophilus influenzae type b (Hib) and non-encapsulated H. influenzae (NTHi) are important pathogens causing invasive and mucosal infections in children. A 42 kDa surface-exposed lipoprotein, protein D, has been found to be a potential virulence factor of NTHi. The gene encoding protein D (hpd) is homologous to the glpQ gene encoding glycerophosphodiester phosphodiesterase in Escheri
Background: Ethanolic fermentation of lignocellulosic biomass is a sustainable option for the production of bioethanol. This process would greatly benefit from recombinant Saccharomyces cerevisiae strains also able to ferment, besides the hexose sugar fraction, the pentose sugars, arabinose and xylose. Different pathways can be introduced in S. cerevisiae to provide arabinose and xylose utilisatio
This essay aims to understand the time and space of the everyday in postindependence Dublin. Methodologically, the approach is hermeneutic. Theory and method can thus not be separated: it is at the same time a heuristic pursuit as an empirical investigation. The Magdalen Asylums, an urban network of coercive state-religious institutions for unmarried women, forms the empirical focal point for the
n this paper we introduce the Mean Effective Radiated Power (MERP) and the Mean Effective Radiated Sensitivity (MERS) as alternative figures of merit of the uplink and downlink communication performance of wireless handheld terminals. We show how they are related to the Mean Effective Gain (MEG), the total radiated power (TRP) and total receiver sensitivity (TRS).
As the Nordic welfare states evolve – with ideologies that focus on an increased consumption of health services – citizens are required to be productive throughout their life course. And because fewer economic resources are being invested into basic health care, and there is a move to shift more responsibility onto the individual (patient), it is becoming essential to illuminate practices that sho
In this article the mediatisation of Zlatan Ibrahimovic's autobiography, written by the journalist David Lagercrantz, is investigated through the reception of the book as well as of other media formats in which it was made public. A main point made is that the processes of mediatisation is a main factor in creating a literary trademark and bestseller. The footballer's mythic life story, as express
This thesis is based on work done 1991-1996 using the DELPHI detector at LEP, and is summarized in four articles. It consists of four main parts. The first part describes the Very Small Angle Tagger (VSAT) and Small angle TIle Calorimeter (STIC), which are sub-detectors of DELPHI. The VSAT consists of four silicon-tungsten electromagnetic calorimeter modules, having silicon strip planes for accur
