Multiconfigurational quantum chemical methods (complete active space self-consistent field (CASSCF)/second-order perturbation theory (CASPT2)) have been used to study the agostic interaction between the metal atom and H(C) in the methylidene metal dihydride complexes H2MCH2, where M is a second row transition metal or the actinide atoms Th or U. The geometry of some of these complexes is highly ir

The crucial role of platelets in maintaining primary hemostais has been evident for a long time and there is now also mounting evidence for their involvement in inflammation. In combination with aspirin, inhibition of the platelet P2Y12 ADP receptor with clopidogrel has become a cornerstone in the antiplatelet in acute coronary syndromes. Recently, several studies have indicated that a considerabl

Objective: To develop a simple, easily administered pencil-and-paper questionnaire to determine the degree to which behavioral patterns play a role in smoking dependence. Methods: A modified Delphi technique was used to identify initial questions and to eliminate obvious duplications. Phase 2 utilized multiple statistical methods (principal components analysis, cluster analysis, stepwise multiple

BACKGROUND: Deep sternal wound infection is a serious and potentially lethal complication of cardiac surgery when performed through a median sternotomy. We describe the outcome of a new treatment strategy with C-reactive protein level-guided vacuum-assisted closure used at our department. METHODS: Data from 16 consecutive adult patients who had deep sternal wound infections after cardiac surgery w

Because of the stratospheric ozone depletion that took place during the last decades of the past century, the effects of ultraviolet radiation on plants, animals, humans and micro-organisms became intensively studied. In this chapter we describe the role of the ozone layer as a radiation shield and various molecular and organismal effects of ultraviolet radiation, with an emphasis on the UV-B band

While the effects of elevated atmospheric CO2 level on starch and sugar metabolism have been extensively studied in different plants, the effect on plant lipid metabolism concerns only a few studies and none of these are on the model plant Arabidopsis thaliana. This study of the lipid composition in seeds and leaves of A. thaliana is therefore of interest when trying to predict how the future envi

This chapter starts with a description of the optics of camera-type eyes, in which an image is projected upon a retina with cornea and lens as refracting elements. Ray tracing is explained with the human eye as an example of a terrestrial vertebrate's eye. Then the comparison is made to camera eyes of aquatic and amphibious animals, with an explanation of different kinds of aberrations, difficulti

To run a Diesel engine in Homogeneous Charge Compression Ignition (HCCI) mode has proved to be a highly promising approach towards reduced engine-out emissions of NOx and particulate matter. A crucial issue when utilizing HCCI is the degree of charge homogeneity that is required to achieve the desired low temperature combustion. A very well mixed charge can be created through the use of traditiona

Scholarship of Teaching and Learning (SoTL) is discussed as a strategy for institutional improvement of teaching and learning. Engagement in SoTL could be an individual enterprise focusing external networks including conference presentations and journal publications. This strategy could lead to development and improved teaching for the individual but not necessarily contribute to the developme

Background. It is expected that fuel cells will play a significant role in a future sustainable energy system, due to their high energy efficiency and possibility to use renewable fuels. Fuels, such as biogas, can be produced locally close to the customers. The improvement for fuel cells during the last years has been fast, but the technology is still in the early phases of development, however th

Limitations on the scattering matrix are derived for a wide class of objects, restricting their broadband interaction with electromagnetic vector spherical waves in terms of their size, shape and static material properties. In particular, it is seen that the order of the dominating term for electrically small objects increases with the order of the spherical wave. The results are applicable to man

Water vapor sorption isotherms are essential data in models to predict the service life of the cement based structures. The knowledge about sorption isotherms in the presence of supplementary cementitous materials (SCMs) is limited. This study investigates the influence of water to cement ratio (0.4, 0.5 and 0.6), and the presence of two SCMs (70% slag and 10% silica fume) on sorption isotherm in

The paper presents a feedback scheduling strategy for multiple control tasks that uses feedback from the plant states to distribute the computing resources optimally among the tasks. Linear-quadratic controllers are analyzed, and expressions relating the expected cost to the sampling period and the plant state are derived and used for on-line sample-rate adjustments. In the case of minimum-varianc
