Dominating Clasp of the Financial Sector Revealed by Partial Correlation Analysis of the Stock Market
2010
What are the dominant stocks which drive the correlations present among stocks traded in a stock market? Can a correlation analysis provide an answer to this question? In the past, correlation based networks have been proposed as a tool to uncover the underlying backbone of the market. Correlation based networks represent the stocks and their relationships, which are then investigated using different network theory methodologies. Here we introduce a new concept to tackle the above question--the partial correlation network. Partial correlation is a measure of how the correlation between two variables, e.g., stock returns, is affected by a third variable. By using it we define a proxy of stoc…
Low-cost materials for boron adsorption from water
2012
[EN] Knowing the affinity of boron aqueous species for cis-diol organic groups, five different hybrid materials have been prepared by anchoring glucose groups onto the surface of silica matrices with a different surface topology: UVM-7 bimodal mesoporous silica, UVM-11 unimodal non-templated mesoporous silica, commercial silica fume and two silica xerogels with pores within the mesoporous range (13-50 nm). After optimizing the experimental conditions, a comparison was made of the boron adsorption capacities in water. The relationship of the structural and functionalization parameters is discussed and the importance of the surface topology in the final adsorption behaviour is revealed. Hence…
Hydrogen Supplied Wireless Charging System for Electric Vehicles
2020
The aim of this work is the experimental characterization of a Wireless Charging System based on IPT (Inductive Power Transfer) supplied by a PEMFC (Proton Exchange Membrane Fuel Cell) in order to verify the possibility of its installation in not electrified areas. A hydrogen-based supply system is designed and assembled with the purpose of having an EV (electrical vehicle) charging station not connected to the main power grid. An efficiency analysis of the wireless transmission system is carried out taking into account external parameters such as distance and misalignment between the transmitter coil and the receiver coil, verifying the integration potentialities of both IPT and fuel cell …
Meldingsovervåkning – en sikkerhet ved sending av elektroniske henvisninger : En kvantitativ studie om ulike faktorers påvirkning på meldingsovervåkn…
2018
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 Using electronic messages is a necessary tool for healthcare providers to be able to perform their work more efficiently. Regarding this, it is very important to maintain an overview and control of the messages that is transmitted between the participants. In order to ensure that a business has procedures for handling application receipts related to electronic messaging, there is a regulatory requirement for how the business should perform this work, both organizational and technical. The purpose of this study is to gain insight into how doctor’s offices in Agder comply with the requirements imposed by the Norwe…
Detection of IgA and IgM antibodies to HIV-1 in neonates by radioimmune western blotting.
1992
OBJECTIVE--To detect infection with HIV-1 by IgA and IgM response at birth in children born to HIV-1 seropositive mothers. DESIGN--Western blotting and radioimmune western blotting on stored sera from infected and uninfected babies born to HIV-1 seropositive mothers. Sera were pretreated to remove IgG. SETTING--Parma and Bologna, Italy. SUBJECTS--12 infected and five uninfected babies born to HIV-1 seropositive mothers and three babies born to seronegative mothers. MAIN OUTCOME MEASURES--Effectiveness of western blotting and radioimmune western blotting in detecting antibodies to HIV-1 gene products. RESULTS--With conventional western blotting we found IgA class antibodies to HIV-1 proteins…
Calculating the regional economic impact of the olympic games
2004
This study introduces a methodological concept to combine the cost‐benefit analysis and input‐output models to create a new method to regionalize Olympic costs and benefits in order to define the economic impact at the regional level. This new form of analysis is used to calculate the regional economic impact of the Frankfurt Rhein/Main region, which bid to stage the 2012 Olympics. A generalised view of the Frankfurt case study shows patterns that are valid for all impact studies of major sport events. Finally a sensitivity analysis is used to determine critical variables.
Bronchoalveolar Lavage and Oleic Acid-Injection in Pigs as a Double-Hit Model for Acute Respiratory Distress Syndrome (ARDS).
2020
The treatment of ARDS continues to pose major challenges for intensive care physicians in the 21st century with mortality rates still reaching up to 50% in severe cases. Further research efforts are needed to better understand the complex pathophysiology of this disease. There are different well-established animal models to induce acute lung injury but none has been able to adequately mimic the complex pathomechanisms of ARDS. The most crucial factor for the development of this condition is the damage to the alveolar capillary unit. The combination of two well-established lung injury models allow us to mimic in more detail the underlying pathomechanism. Bronchoalveolar lavage (BAL) leads to…
The Phenomenon of Social Enterprise in Austria: A Triangulated Descriptive Study
2011
Abstract There is little to no existing research on the phenomenon of social enterprises (SEs) in Austria. To enable subsequent comparative studies, the author first traces social enterprises' conceptual underpinnings from most current research found in leading journals and subsequently creates a framework based upon social origins theory for use on Austria's social enterprises. In order to validate the findings, the author employs a triangulated research approach, including an online-based survey, semi-structured interviews and two panel discussions. Social enterprises in Austria are characterized through social activities, organizational types, legal forms, the society sector, the outcome…
Respiratory gas exchange in the rat spleen in situ and intrasplenic oxyhemoglobin saturation.
1979
Measurements of splenic respiratory gas exchange and of HbO2 saturations in the red pulp of the rat spleen have shown that there are no indications of a reduced intrasplenic O2 availability during normoxia. The present studies provide evidence that, in the normal spleen, the intrasplenic sequestration of red blood cells cannot be explained by an O2 deficiency in the red pulp since the commonly accepted notion of an intrasplenic hypoxia is not true.
Molte Palermo. Temi
2019
Nel tema delle incompiute idee di città possibili si riconoscerà il paradigma connotativo dello stesso divenire di Palermo, lungo un percorso millenario di processi di trasformazione nessuno dei quali portato a compimento, in virtù di quel valore distintivo di exemplum che non necessita di ulteriori e conclusive dimostrazioni. Il corso della storia, del resto, ha imposto a Palermo il ciclico riproporsi di destini interrotti. Tale si rilevò l’invenzione della città capitale, quella della “quadratura geometrica e della croce di strade” sovrimpressa a quella archetipica e fondativa della Pan-ormos scambiatrice. E l’incompiutezza sarà il tratto distintivo della città dei rettifili stradali otto…
