Supporting Semantic Capture during Kinesthetic Teaching of Collaborative Industrial Robots

Industrial robot systems being deployed today do not contain domain knowledge to aid robot operators in setup and operational use. To gather such knowledge in a robot context requires mechanisms for entering and capturing semantic data, that will gradually build a working vocabulary while interacting with environment and operators, for bootstrapping system knowledge and ensuring data collection ov

Catalytic C-H oxidations by nonheme mononuclear Fe(II) complexes of two pentadentate ligands: Evidence for an Fe(IV) oxo intermediate

The oxidation reactions of alkanes with hydrogen peroxide and peracids (peracetic acid (PAA) and m-chloroperoxybenzoic acid (mCPBA)) catalysed by two Fe(II) complexes of pentadentate {N5}-donor ligands have been investigated. Kinetic isotope effect experiments and the use of other mechanistic probes have also been performed. While the total yields of oxidized products are similar regardless of oxi

Expression of tomato thymidine kinase 1 by means of the baculovirus expression vector system

Tomato thymidine kinase 1 (ToTK1) is a deoxyribonucleoside kinase (dNK) that has been subject to study because of its potential to phosphorylate the nucleoside analogue 3-azido-2,3-dideoxythymidine (azidothymidine, AZT) equally well as its natural substrate thymidine (dThd). The combination of ToTK1 and AZT has been tested in two animal studies for its efficiency and use in suicide gene therapy fo

Quality-of-life after bile duct injury : intraoperative detection is crucial. A national case-control study

Background Existing reports on quality-of-life (QoL) after bile duct injury (BDI) are conflicting. Methods Case-control study were QoL assessment was performed using SF-36 (36-item short Form health survey). Patients with BDI were compared to a matched control group (1:2) subject to cholecystectomy. Results In total 168 BDIs (0.3%) were eligible for participation and 64% returned SF-36. Median fol

Outcome of neoadjuvant therapies for cancer of the oesophagus or gastro-oesophageal junction based on a national data registry

Background: Randomized trials have shown that neoadjuvant treatment improves survival in the curative treatment of oesophageal and gastro-oesophageal junction cancer. Results from population-based observational studies are, however, sparse and ambiguous. Methods: This prospective population-based cohort study included all patients who had oesophagectomy for cancer in Sweden, excluding clinical T1

The GHG-CCI project of ESA's climate change initiative : Data products and application

The goal of the GHG-CCI project (http://www.esa-ghg-cci.org/) of ESA's Climate Change Initiative (CCI) is to generate global atmospheric satellite-derived carbon dioxide (CO2) and methane (CH4) data sets as needed to improve our understanding of the regional sources and sinks of these important greenhouse gases (GHG). Here we present an overview about the latest data set called Climate Research Da

Reaction Mechanism for Olefin Exchange at Chloro Ethene Complexes of Platinum(II)

Synopsis In methanol solutions of Zeise's salt, the parent complex [PtCl3(C2H4)]- as well as its solvolysis product, trans-[PtCl2(C2H4)(MeOH)], exchange rapidly with free ethene. The olefin exchange process, which is largely entropy controlled, involves the substitution labile site trans to the coordinated ethene. Abstract Complex equilibria in methanol/chloroform/dichloromethane solutions contain

Iron-Manganese Redox Processes and Synergism in the Mechanism for Manganese-Catalyzed Autoxidation of Hydrogen Sulfiite

SynopsisOn the basis of kinetic studies of the manganese-catalyzed autoxidation of sulfite and thermodynamic data for iron−manganese redox processes and manganese(II) and -(III) protolysis equilibria, the catalytically active species in the autoxidation is concluded to be a mixed-valence oxo-bridged manganese(II,III) complex. Iron−manganese synergism and triggering of the chain reaction by small c

Kinetics and mechanism for reduction of trans-dichlorotetracyanoplatinate(IV) by tetraammineplatinum(II) and bis(ethylenediammine)platinum(II)

Reduction of trans-[Pt(CN)(4)Cl-2](2-) by [Pt(NH3)(4)](2+) and [Pt(en)(2)](2+) was studied at 25 degrees C in the range 0 less than or equal to [Cl-] less than or equal to 0.4 M by use of stopped-flow spectrophotometry. The stoichiometry [Pt(IV)]:[Pt(II)] is 1:1. Rapid-scan spectra show clear-cut isosbestic points, indicating that no reaction intermediates are accumulated to a significant amount.

Kinetics for interaction of the thione unit in 4-thio-2'-deoxyuridine and 4-thiouridine 5'-monophosphate with rapidly reacting gold(III) complexes

Reactions of 4-thio-2′-deoxyuridine d(s4U) and 4-thiouridine 5′-monophosphate s4UMP with trans-[AuY2Cl2]+/– (Y = CN– or NH3) have been investigated by conventional and high-pressure stopped-flow spectrophotometry in aqueous solution with 2.9 ⩽ pH ⩽ 7.0. For a given combination of metal complex and sulfur donor the observed second-order rate constants decreased with increasing pH. In the pH range 2

Pesticide exposure and neurodevelopment in children aged 6–9 years from Talamanca, Costa Rica

Certain pesticides may affect children's neurodevelopment. We assessed whether pesticide exposure was associated with impaired neurobehavioral outcomes in children aged 6–9 years. We conducted a cross-sectional study in 140 children living near banana plantations and plantain farms in the Talamanca County, Costa Rica and assessed their neurobehavioral performance. Exposure was determined by analyz

Assistive products and the Sustainable Development Goals (SDGs)

The Sustainable Development Goals (SDGs) have placed great emphasis on the need for much greater social inclusion, and on making deliberate efforts to reach marginalized groups. People with disabilities are often marginalized through their lack of access to a range of services and opportunities. Assistive products can help people overcome impairments and barriers enabling them to be active, partic

Decarbonising the energy intensive basic materials industry through electrification – Implications for future EU electricity demand

The need for deep decarbonisation in the energy intensive basic materials industry is increasingly recognised. In light of the vast future potential for renewable electricity the implications of electrifying the production of basic materials in the European Union is explored in a what-if thought-experiment. Production of steel, cement, glass, lime, petrochemicals, chlorine and ammonia required 125
