The social and environmental impact associated with consuming a product is something that is becoming increasingly important to consumers and businesses alike. This impact can in theory be computed simply by classifying a product and by mapping the classified product to the corresponding life-cycle assessments research. However, this type of mapping requires an extensive product taxonomy with a la
This Master Thesis has been written at EADS (European Aeronautic Defence and Space Company) Airbus in Bremen.The work contains a description of a few methods when linearising SystemBuild models in MATRIXx. MATRIXx is a tool for matrix manipulations (similar to Matlab) and SystemBuild is a graphical modeling environment (similar to SimuLink). The methods examined are the linearization command “lin”
The purpose of this project was to investigate fast photoneutron production from a series of materials commonly used for backing neutron beam guides. Fast neutrons were knocked out of these materials by exposing them to to high-energy photons at the Tagged-Photon Facility at MAX-lab in Lund, Sweden. Liquid scintillator detectors at different angles around the targets registered the photoknockout n
The purpose of this paper is to compare a collection of control variates for Monte Carlo-valuation of spread options on three assets with a view towards energy markets and to lay a foundation for continued research on control variates, e.g. combinations of control variates and adaption for quasi-Monte Carlo. The paper builds upon previous research on option pricing using Monte Carlo-simulation and
General studies of medieval logic tend to neglect the context in which medieval logic developed and the needs to which such a development responded. Accordingly, they normally neglect the non-formal elements they encounter instead of integrating them as elements that meet the specific needs of the medieval intellectual endeavour and that are, then, part and parcel of medieval interpretations of Ar
We propose an extended Left-Right symmetric model with an additional global U(1)X symmetry, which collapses to a residual subgroup ℤ2 after spontaneous symmetry breaking. In this model, the light active neutrino masses are generated via a double seesaw mechanism with the Dirac submatrix arising at one loop. In addition, the masses of the charged fermions of the Standard Model (SM) that are lighter
This paper considers adaptive schemes for the simultaneous monitoring of the mean and variability of a multivariate normal quality characteristic. At first, we extend an already existing bivariate non-adaptive simultaneous control chart to a multivariate one. Then, we develop several adaptive schemes, which will cover both previously bivariate and newly multivariate charts. After having designed a
Obesity is a key factor for cardiovascular diseases and complications. Obesity is associated with hypertension, dyslipidemia and type II diabetes, which are the major predictors of cardiovascular disease in the future. It predisposes for atrial fibrillation, heart failure, sudden cardiac death, renal disease and ischemic stroke that are the main causes of cardiovascular hospitalization and mortali
Celiaki förekommer hos 0,5–1 procent av befolkningen. Majoriteten av dem med celiaki har atypiska symtom och är inte diagnostiserade. Personer med vissa kromosomrubbningar eller annan autoimmun sjukdom och nära släktingar till personer med celiaki tillhör riskgrupper där screening kan rekommenderas. IgA-endomysie- eller IgA-transglutaminasantikroppar har båda hög specificitet och hög sensitivitet Coeliac disease is widespread and occurs in 0.5-1 per cent of the population. Most sufferers show atypical symptoms and might well remain undiagnosed. Endomysial or human transglutaminase autoantibody levels of type IgA can be recommended as screening instruments combined with s-IgA for exclusion of such deficiency. In contrast, there is a high frequency of false-positive IgA gliadin antibody test
Yacón root is a natural source of fructans, which has many potential benefits. Convective drying has been applied to increase the shelf life of yacón roots. However, this processing may lead to detrimental effects on the physicochemical functionality. The drying was investigated using different conditions (drying temperatures of 45 °C, 50 °C and 55 °C at a drying air velocity of 2 m/s and 60 °C at
Agriculture is vulnerable to the interannual climate variability and to its unpredictability, in such a way that most agricultural decisions taken within the time horizon of several months are made in a conservative manner, supposing a near-pessimist scenario. The improvement of climate prediction may help the strategic view, mitigating unwanted impacts and taking advantage of favorable conditions
A 62-year-old previously healthy woman presented with a centroblastic non-Hodgkin's lymphoma in the thyroid. Chromosome analysis revealed two unrelated clones, 47,XX,+5 and 46,XX,-14,+der(14)t(5;14)(q11;q32). The two clones may reflect a polyclonal origin, or they may be the descendants of the same neoplastically rearranged cell. In the latter case, the clonal aberrations are either secondary to a
The heat of reaction of mercury diphenyl with hydrogen chloride in benzene solvent has been measured at 25°C. The heat of reaction of mercury diphenyl with mercuric chloride in methanol solvent has also been measured. From these heats of reaction, the heat of formation of mercury diphenyl has been derived: ΔHf° (Hgφ2, cryst.) = 65.4 ± 2 kcal/mole. Previous data on the heats of reaction of mercury
In 2014, a new initiative was undertaken by groups working on plans for the transplantation of stem-cell-based derived dopaminergic neurons for treating Parkinson’s disease patients. This GForce-PD group held its annual meeting on 18–19 April 2016 in Chicago at Rush University to discuss their progress and the challenges that the translation of this experimental therapy still faces. Over 2 days, t
Soft-tissue sarcomas are rare diseases with >50 subtypes. Surgery is the most important treatment in localized disease, sometimes combined with radiotherapy. Chemotherapy is used as palliation in advanced disease, sometimes also with a potential to decrease tumour size and eradicate micro-metastases, making meaningful surgery possible. The role of chemotherapy as adjuvant treatment in localized di
