Large companies in today’s business environment are to a great extent depending on their credit score by rating institutes like Moody’s and Standard & Poor’s. There is however indications that these big institutes are not always rating companies accurately. This is why this thesis aims at developing a new credit rating model, CRITA-Score, with the objective of determining a company’s financial
Background: The Swedish National Register for Oesophageal and Gastric Cancer (NREV) was launched in 2006. Data are reported at diagnosis (diagnostic survey), at the time of surgery (surgical survey) and at first outpatient follow-up (follow-up survey). The aim of this study was to evaluate data originating from NREV in terms of comparability, completeness, accuracy and timeliness. Methods: Coding
Let N be the number of classes in a population to be estimated. Fix any preassigned error probability 0
Fast-moving consumer goods (FMCGs) are products that have a short useful lifetime and are typically designed for single or limited uses followed by disposal. The disposable nature of FMCGs combined with ineffective waste recovery systems is causing global environmental problems. Various reusable packaging business models have emerged to tackle these problems; however, their influence is still low
The presented "spot-on-a-chip" technology enables easy enrichment of samples in the low nanomolar (1-5 nM) range and provides a fast and reliable automated sample preparation method for performing matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) analysis with high sensitivity and throughput. Through microdispensing, which allows accurate deposition of 60-
Background: No studies to specifically determine the prevalence of contact allergy to acrylates/methacrylates in patch tested populations have been published. Objectives: To determine the prevalence of acrylate/methacrylate allergy in all patients tested to the baseline patch test series. Methods: Five acrylate/methacrylate allergens (2-hydroxyethyl methacrylate, methyl methacrylate, ethylene glyc
Meadow vipers (Vipera ursinii) are small venomous snakes whose range in Hungary has been greatly fragmented by anthropogenic habitat disturbance (especially, agriculture). We obtained DNA from a total of eight Hungarian snakes. Genetic variability at the major histocompatibility (Mhc) class I loci was much lower for these snakes than for specimens from two large Ukrainian populations. Within two H
Some preliminary tests at the crystallography beamline I711 at the MAX II synchrotron in Lund, Sweden, have shown that it is possible to use acoustical levitation to keep a droplet of liquid and solid (powder) samples in an X-ray beam for a sufficient time for collection of the X-ray diffraction pattern.
In this article we describe simulations of the hadronic decay of Higgs bosons produced in association with vector bosons at linear and hadronic colliders. We use the Monte Carlo at next-to-leading-order (MC@NLO) matching prescription with the Herwig++ event generator to predict various spectra of the resulting b (b) over bar pairs and compare our results with leading order and matrix element corre
Desferrioxamine-B (DFOB) is a bacterial trihydroxamate siderophore and probably the most studied to date. However, the manner in which DFOB adsorbs at mineral surfaces and promotes dissolution is still under discussion. Here we investigated the adsorption and dissolution reactions in the goethite-DFOB system using both in situ infrared spectroscopic and quantitative analytical methods. Experiments
Background: A time-geographic diary approach is of interest in occupational therapy due to the inclusion of the diarist’s subjective experiences. There are several methods for detecting doing in time, but details needed for analysis are still lacking. The smartphone application POrtable Diary Data collector (PODD), a 24-hr diary based on the time-geographic diary has recently been introduced. Aim:
Lunds universitet fick i uppdrag av Kemikalieinspektionen att kartlägga och beskriva ansatser till metoder som bedömer indirekta effekter av växtskyddsmedel på individer och populationer och studier som utvärderar om nuvarande riskbedömningsmetoder är tillräckliga för att bedöma direkta effekter av växtskyddsmedel på biologisk mångfald. Uppdraget utfördes i två delar. För det första inventerade viLund University was commissioned by the Swedish Chemicals Agency to map and describe emerging methodologies that assess the indirect impact of plant protection products on nontarget organism individuals and populations, and studies that evaluates if current risk assessment methodologies are sufficient to assess direct effects of plant protection products on biodiversity. The commission was perform
In this paper we present the matched window reassignment method, generalizing the results to complex valued signals in multiple dimensions. For an oscillating transient signal with an envelope shape described by an arbitrary twice differentiable function, the reassigned spectrogram, with a matched window, concentrates all energy into one single time-frequency point. An estimator for the parameters
Brazil's Araucaria tree (Araucaria angustifolia) is an iconic living fossil and a defining element of the Atlantic Forest global biodiversity hotspot. But despite more than two millennia as a cultural icon in southern Brazil, Araucaria is on the brink of extinction, having lost 97% of its extent to 20th-century logging. Although logging is now illegal, 21st-century climate change constitutes a new
