Semiconductor nanowire arrays are a promising candidate for next generation solar cells due to enhanced absorption and reduced material consumption. However, to optimize their performance, time consuming three-dimensional (3D) opto-electronics modeling is usually performed. Here, we develop an accurate one-dimensional (1D) modeling method for the analysis. The 1D modeling is about 400 times faster
Purpose: To study the impact of dose fractionation of adjuvant radiation therapy (RT) on local recurrence (LR) and the relation of LR to radiation fields. Methods and Materials: LR rates were analyzed in 462 adult patients with soft tissue sarcoma who underwent surgical excision and adjuvant RT at five Scandinavian sarcoma centers from 1998 to 2009. Medical records were reviewed for dose fractiona
PURPOSE: To analyze the visual outcome after cataract surgery. SETTING: Cataract surgery clinics in 15 European countries. DESIGN: Database study. METHODS: Data were drawn from case series of cataract extractions reported to the European Registry of Quality Outcomes for Cataract and Refractive Surgery database. These data were entered into the database via the Web by surgeons or by transfer from e
Value added tax (VAT) is a key part of the fiscal revenue of many countries. Yet this broad-based tax on consumer spending exempts financial services. This seems puzzling to many, particularly given the significance of that sector and the size of its value-added in today's world economy. The fact that the European Commission is currently reviewing the tax treatment of financial activities in the E
The acid-catalyzed rearrangement of 1,4,5,8-tetramethylnaphthalene was used to determine the acidity of media used for EPR spectral studies of radical cations. The radical cations of methyl-substituted naphthalenes were shown to undergo dimerization reactions. The apparent persistency of the radical cation of hexamethylbenzene was due to the slow oxidation when thallium(III) trifluoroacetate was
Delamination and spallation of thermal barrier coating (TBC) systems, used in hot parts of gas turbines, have been studied with respect to thermal fatigue. TBCs with and without pre-existing cracks were investigated. Thermal shock tests were performed until coating spallation. The experimental results revealed that the cracks primarily responsible for spallation grew horizontally, close to the int
In this chapter, we compare the class composition of four types of anti-austerity demonstrations—Occupy/Indignados, trade union, May Day and other anti-austerity protests—with “new social movement” demonstrations. This allow us to, firstly, scrutinize whether contemporary anti-austerity protests attract more participants from the lower classes—in particular the working class—than from the upper st
This paper describes the development of a method based on measurements of the radar cross section (RCS) in the forward direction to determine the extinction cross section for the 2.5 – 38 GHz frequency range. A conventional anechoic chamber designed for monostatic measurements is used for forward RCS measurements. The extinction cross section is then calculated from the measured forward RCS using
Popular Abstract in Swedish Reglering av celltillväxt och celldöd är mycket viktigt för bibehållandet av balansen mellan antalet olika celler i kroppen. Om regleringen rubbas kan olika sjukdomar uppkomma, som karakteriseras av för mycket celltillväxt eller av för mycket celldöd. Exempel är cancer, där man har för mycket tillväxt, samt många degenerativa sjukdomar som diabetes, Parkinsons och aids,
Popular Abstract in Swedish Många av de äldre patienterna som är inlagda på sjukhus eller som bor i särskilda boenden inom äldreomsorgen är idag undernärda. En sammanställning av Socialstyrelsen över svenska studier under de senaste 20 åren visade på en genomsnittlig frekvens av undernäring på 28%. Ett otillräckligt kostintag leder till undernäring. Kroniska sjukdomar är ofta en bakomliggande orsThe aim of this thesis was to develop and test the feasibility of a dietary record routine, where nursing staff assess the patient’s food and fluid intake based on standardised portion sizes and household measurements. The energy intake (EI) was studied with a dietary record in 61 geriatric patients. During the 6-month follow-up 11 patients died and an EI below median (1378 kcal) was associated w
Popular Abstract in Swedish Avhandlingen är en tematisk och historisk studie av Sjömans filmer och av hans betydelse för svensk filmkultur, framför allt under 1960- och 1970-talen. Sjöman är mest känd som filmregissör. År 1962 hyllades debutfilmen Älskarinnan av kritikerna. Sjöman sågs som föregångare till en ny våg i svensk film. Genom debatten efter filmcensurens totalförbud av 491 (1964) kom Sj
The modeling of industrial combustion applications today is almost exclusively based on two-equation turbulence models. Despite its known limitations, the most the widely used model is still the standard k-ε model. The objective of this paper is to investigate the performance of two-equation turbulence models applied to a confined swirling flow. Numerical modeling of an axis-symmetric confined sud
OBJECTIVE: To form a methodologic basis for DNA analysis of ductal carcinoma in situ (DCIS) and invasive carcinoma (IC) of the breast, including very small lesions, by comparison of flow cytometric (FCM) and image cytometric (ICM) methods for DNA quantitation. STUDY DESIGN: The material consisted of 41 DCIS lesions and 26 ICs. FCM DNA analysis of unfixed, frozen samples were compared to (1) FCM of
Time domain reflectometry (TDR) is a widely used method for measuring the dielectric constant (K-a) and bulk electrical conductivity (sigma(a)) in soils. The TDR measured sigma(a) and K-a can be used to calculate the soil solution electrical conductivity, sigma(w.) The sigma(w), in turn, can be related to the concentration of an ionic tracer. Several models of the sigma(w)-sigma(a)-K-a relationshi
Studies of apparently homogeneous cell populations and single cells often give highly divergent results. Cells exhibit varying responsiveness to stimuli and gene expression and they are in many aspects stochastic and unpredictable. We have developed a method to measure gene expression quantitatively in individual cells with real-time RT-PCR. mRNA for hormones, ion channels and enzymes in pancreat
Background: Pharmacodynamic investigations with antimicrobials define the relationship between the infecting organism and achievable drug concentrations with clinical outcome. Objective: To examine this relationship for meropenem in a population of patients who are at high risk of infection-related morbidity and mortality. Methods: The study was a retrospective analysis of a multicenter, randomize
Background. The objectives of this report are to evaluate changes in the preterm birth rate in Sweden 1973-2001. Furthermore, describe the proportion of spontaneous and indicated preterm births and assess risk factors for the subgroups of preterm birth during the period from 1991 to 2001. Methods. A population-based register study of all births occurring in Sweden from 1973 to 2001 registered in t
