Representation and Self-Awareness in Intentional Agents
Several conditions for being an intrinsically intentional agent are put forward. On a first level of intentionality the agent has representations. Two kinds are described: cued and detached. An agent with both kinds is able to represent both what is prompted by the context and what is absent from it. An intermediate level of intentionality is achieved by having an inner world, that is, a coherent

A Single Injection Ultrasound-Assisted Femoral Nerve Block Provides Side Effect-Sparing Analgesia When Compared with Intrathecal Morphine in Patients Undergoing Total Knee Arthroplasty
Postoperative pain after total knee arthroplasty (TKA) is severe, and achieving adequate analgesia remains a clinical challenge. We tested the hypothesis that, in patients having unilateral TKA under intrathecal (IT) anesthesia, the addition of a femoral nerve block would provide superior analgesia when compared with IT morphine and demonstrate fewer adverse side effects. In a single-blinded and c
Oxomolybdenum(III, IV and V) complexes of thiofunctional ligands
Reaction of [MoO2(acac)(2)] with Li2NS2S'(2), (S is a thioether, S' a thiophenolate function) yielded the compound Li-7(thf)(17){MoO}(8)center dot 10thf center dot hexane, where {MoO}(8) represents one [(MoO)-O-IV(NS2S'(2))] 1, three [(MoO)-O-III(NS2S'(2))](-) (2, linked, via the oxo group, to [Li(thf)3](+)) and two [(MoO)-O-V(S'(2))(2)](2-)(2) .A mixed-valent variant of 3, [{(MoO)-O-IV(S'(2))} {(
A model for the absorption of sulphur dioxide into a limestone slurry
A model has been developed for the removal of sulphur dioxide from flue gas by absorption into a limestone slurry. The flue gas desulphurization unit consists of an absorber tower and an oxidation tank. Flue gas enters the absorption tower at the bottom and meets the limestone slurry. There are five important chemical reactions with a finite rate. The rate-limiting reactions are limestone dissolut
Efficient Oncoretroviral Transduction of Extended Long-Term Culture-Initiating Cells and NOD/SCID Repopulating Cells: Enhanced Reconstitution with Gene-Marked Cells Through an Ex Vivo Expansion Approach.
Recent developments of surrogate assays for human hematopoietic stem cells (HSC) have facilitated efforts at improving HSC gene transfer efficiency. Through the use of xenograft transplantation models, such as nonobese diabetic/severe combined immunodeficiency (NOD/SCID) mice, successful oncoretroviral gene transfer to transplantable hematopoietic cells has been achieved. However, because of the l
Job strain, decision latitude and alpha2B-adrenergic receptor polymorphism significantly interact, and associate with higher blood pressures in men.
Background Job strain (high demands and low decision latitude) and the DID genotype of an I/D polymorphism in the adrenergic alpha(2B)-receptor have been associated with hypertension, respectively. We hypothesized that the I/D polymorphism interacts with external stress, such as job strain, in the development of hypertension. Methods A sample of 3045 employed men and women from the population coho
Global dispersion of right atrial repolarization in healthy pigs and patients
Objective - To investigate the feasibility of monophasic action potential ( MAP) mapping using an electro-anatomical mapping system ( CARTO) in obtaining information on global dispersion of atrial repolarization and to evaluate the role of dispersion of repolarization in the genesis of paroxysmal atrial fibrillation ( PAF). Methods and results - Right atrial MAPs were recorded from 53 +/- 18 sites
Hyperpolarized Nuclei for NMR Imaging and Spectroscopy – Methodology and model studies of lung and vascular function
Based on the principle of nuclear magnetic resonance (NMR), magnetic resonance imaging (MRI) and magnetic resonance spectroscopy (MRS) are widely used methods in medical diagnostic imaging and biological research. Clinical MRI has been restricted to imaging of protons, for reasons of sensitivity. In recent years, hyperpolarization techniques have emerged that can increase the NMR signal by 5–6 ord
"Readbacks" or Tradition? The Kluskap Stories among Modern Canadian Mi'kmaq
When ethnographers in the 1950s and 1960s did fieldwork among the Canadian Mi’kmaq Indians, they were worried about the future of Mi’kmaq culture. Not many Mi’kmaq in the thirties had heard about their traditional culture hero Kluskap, and if they had, it was through books or the television series “The Adventures of Glooscap”. Thirty years later, in 1989, the Mi’kmaq strongly rejected the plans t
Latency of cathepsin B secreted by human colon carcinoma cells is not linked to secretion of cystatin C and is relieved by neutrophil elastase
The lysosomal cysteine proteinase cathepsin B is shown to be secreted by ten human colon carcinoma cell lines and to accumulate in culture media as a latent enzyme. The cell lines also secrete a physiological inhibitor of cathepsin B, cystatin C. A significant correlation was found between secretion of the latent enzyme and the inhibitor (r = 0.755, P < 0.01). The aim of the present study was to m
Wind erosion on arable land in Scania, Sweden and the relation to the wind climate - a review
This paper addresses variations in the wind climate in relation to changes in the impact of wind erosion on agricultural lands with Scania, the southernmost province of Sweden, as an example. The literature concerning wind erosion in the region is reviewed and the conclusions are linked to recent analyses of the regional wind climate. Presently, wind erosion occasionally induces problems in light
A case study of successful e-learning: A web-based distance course in medical physics held for school teachers of the upper secondary level
Learning activities and course design in the new context of e-learning, such as in web-based courses involves a change both for teachers and students. The paper discusses factors important for e-learning to be successful. The development of an online course in medical physics and technology for high school teachers of physics, details of the course, and experience gained in connection with it are

Light-induced linear dichroism in photoreversibly photochromic sensor pigments 3. Chromophore rotation estimated by polarized-light reversal of dichroism
Phytochrome from oats (Avena sativa L. cv. Sol II), partially purified on brushite, was immobilized on Sepharose beads to which antiphytochrome immunoglobulin had been covalently linked. The immobilized phytochrome was first brought to the Pr form with unpolarized far-red light. The change in linear dichroism at 660 nm induced by plane polarized red light, and its reversal by plane polarized far-r
