The 1,3-bis[di(4-methoxyphenyl)amino]azulene 1 and 1,3-bis[di(4-methoxyphenyl)amino]azulene-2-carboxylic acid methyl ester 2 were synthesized and investigated by spectroscopic and electrochemical methods in order to estimate the electronic coupling between the attached amine redox centers. We found that the electronic coupling V which is mediated by a nonalternant 1,3-azulene bridge in the radical
Ab initio calculations of low-lying electronic states of CrH are presented, including potential energies, dipole and transition dipole moment (TDM) functions, and radiative lifetimes for X (6)Sigma(+), A (6)Sigma(+), 3 (6)Sigma(+), 1 (6)Pi, 2 (6)Pi, 3 (6)Pi, and (6)Delta. Calculation of dynamic correlation effects was performed using the multistate complete active space second-order perturbation m
In the present paper, we have studied particle dissolution and crystal growth of the poorly water soluble drug felodipine, using fluorescence as a probe for the amount of crystalline material. Dissolution kinetics is essentially diffusion-controlled, while the rate of crystal growth is significantly slower compared to the diffusion-controlled limit. The deviation from diffusion control was charact
BACKGROUND: Traditionally oocytes have been exposed to sperm overnight, for 16-20 h. This long period of co-incubation, however, has been shown to create problems with high levels of reactive oxygen species (ROS), which may affect embryo viability and cause hardening of the zona pellucida. Recently, a positive effect of reducing the co-incubation time to 90-120 min was reported. The objective of t
Background: Lung densitometry is an effective method to assess overall progression of emphysema, but generally the location of the progression is not estimated. We hypothesized that progression of emphysema is the result of extension from affected areas toward less affected areas in the lung. To test this hypothesis, a method was developed to assess emphysema severity at different levels in the lu
This talk describes the various stages of ATLAS Data Challenge 2 (DC2) in what concerns usage of resources deployed via NorduGrid's Advanced Resource Connector (ARC). It also describes the integration of these resources with the ATLAS production system using the Dulcinea executor. ATLAS Data Challenge 2 (DC2), run in 2004, was designed to be a step forward in the distributed data processing. In p
This paper describes in what ways hierarchical organizations influence the utilization and dissemination of knowledge. Particular attention will be paid to the role that tacit knowledge has. The reporting system of incidents is one element in a larger institutional process, often termed 'lessons learned' (LL). This process helps to suggest solutions to identify shortcomings and facilitates in maki
The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. Special interest was drawn to the dynamic processes such as start-up, r
Conflicts between project stakeholders can stop or damage a construction project as well as technical problems. It is not uncommon that projects are stopped or changed late in the process with the effect that large amounts of already made investments becomes obsolete. One explanation of this phenomena is the escalation of project decisions, where project managers persist with a course of actions l
We analyze how the interaction between two hydrophobic surfaces in water depends on the amount of dissolved gas. At equilibrium there is, for a truly hydrophobic surface with contact angle theta > 90degrees, a long range attractive force. The attraction is due to the formation of a gaseous film between the surfaces. For a completely degassed sample the gas consists of water vapor and the range of
High efficiency, environmental friendliness, low operation and maintenance costs, and the lowest possible impact on the environment are some of the requirements of sustainable energy production. In the selection of new power generation systems, a number of steps have to be taken into account in order to meet these requirements. Here, the first law analysis has been implemented and investigated, fo
Background: Cellular interactions elicited by Plasmodium falciparum erythrocyte membrane protein antigen 1 (PfEMP1) are brought about by multiple DBL ( Duffy binding like), CIDR ( cysteine-rich interdomain region) and C2 domain types. Elucidation of the functional and structural characteristics of these domains is contingent on the abundant availability of recombinant protein in a soluble form. A
OBJECTIVES: To estimate the total direct medical costs to society for patients with type 2 diabetes in Sweden and to investigate how different factors, for example diabetic late complications, affect costs. DESIGN: Cross-sectional data regarding health care utilization, clinical characteristics and quality of life, were collected at a single time-point. Data on resource use cover the 6-month perio
Popular Abstract in Swedish Inför hjärtkirurgi är bedömning av en patients individuella nytta av och risk vid en hjärtoperation en viktig komponent i utredningen inför operationen. En riskstratifiering innebär att patientens olika riskfaktorer (exempelvis sockersjuka, högt blodtryck, antal tidigare hjärtinfarkter, hjärtfunktion) vägs samman till en sannolikhets-bedömning av risken för en viss händThe aims of this research was to compare different risk score algorithms with regard to their validity to predict 30-day and one-year mortality after open-heart surgery, to evaluate if the preoperative risk stratification model EuroSCORE predicts the different components of resource utilization in cardiac surgery, and to systematically evaluate the accuracy and performance of artificial neural net
The perennial herbaceous crop Arundo donax is a potential feedstock for second-generation bioethanol production. In the present work, two different process options were investigated for the conversion of two differently steam-pretreated batches of A. donax. The pretreated raw material was converted to ethanol with a xylose-consuming Saccharomyces cerevisiae strain, VTT C-10880, by applying either
We use a nested-grid version of the GEOS-Chem chemistry transport model, constrained by isoprene emissions from the Model of Emissions of Gases and Aerosols from Nature (MEGAN), and the Lund-Potsdam-Jena General Ecosystem Simulator (LPJ-GUESS) bottom-up inventories, to evaluate the impact that surface isoprene emissions have on formaldehyde (HCHO) air-mass factors (AMFs) and vertical column densit
The combustion and melt dripping of poly(ethylene-co-butyl acrylate) (EBA), EBA blended with polypropylene (EBAePP) and poly (ethylene-co-methacrylic acid) (EMAA), each blended with calcium carbonate and polydimethylsiloxane, were studied. In situ measurement of the temperature gradient in the cone calorimeter were combined with infrared spectroscopy measurements on specimens withdrawn and quenche
There are many different factors that influence our perception of products i.e. personal, product related and external factors. For designers to be able to address them all when creating new products, we need to deepen our understanding of the totality of perceptual experiences from non-instrumental interaction with products. One way of achieving this is by stimulating the creative process by util
Media coverage of the Israeli–Palestinian conflict does not necessarily enhance one’s knowledge or understanding of the Palestinians; on the contrary they are often reduced to either victims or perpetrators. Similarly, while many academic studies devote considerable effort to analyzing the political situation in the occupied territories, there have been few sophisticated case studies of Palestinia
