Crystal structure of chlorido(2-{[2-(4-chlorophenyl)hydrazin-1-ylidene-κN1](phenyl)methyl}pyridine-κN)(η5-pentamethylcyclopentadienyl)iridium(III) te…

2015

The title compound, [Ir(η5-C5Me5)Cl(C18H14ClN3)]B(C6H5)4, is chiral at the metal center and crystallizes as a racemate. In the cation, the hydrazinylidenepyridine ligand isN,N-coordinated through theN-pyridyl andN-hydrazinylidene groups forming a five-membered metallacycle. An intramolecular C—H...Cl hydrogen bond is observed. In the crystal, centrosymmetrically-related cations are connected by C—Cl...π interactions, forming a dimeric structure. The crystal packing is further stabilized by weak interionic C—H...π interactions.

rac-11-Selena-12,13-diazabicyclo[10.3.0]pentadeca-10a(13a),12-dien-1-ol

2021

The title compound, C12H20N2OSe, crystallizes in strands of enantiomeric molecules connected via O—H...N hydrogen bonds. There are only slight deviations from an ideal gauche conformation in the decamethylene chain, indicating just a little strain.

rac-12-Selena-13,14-diazatricyclo[9.3.0.02,4]tetradeca-11,13-diene

2020

The centrosymmetric crystal structure of the title compound, C11H16N2Se, is built up from alternating strands of (R,R)- and (S,S)-enantiomers. These strands, which propagate along the c-axis direction, are composed of homochiral molecules related to each other by twofold screw axes. The shape of the molecule is an almost planar unit around the selenadiazole ring with a hexamethylene chain as an arched handle.

Anti-Transglutaminase Antibody Assay of the Culture Medium of Intestinal Biopsy Specimen Can Improve the Accuracy of Celiac Disease Diagnosis.

2006

BACKGROUND: We measured anti-transglutaminase (anti-tTG) antibody in the culture medium of intestinal biopsy specimens from patients with suspected celiac disease (CD) and evaluated the relationship between antibody production and severity of intestinal mucosal damage. METHODS: We performed diagnostic testing for CD on 273 consecutive patients. In addition to routine histologic evaluation of duodenal biopsy specimens, we assayed anti-tTG antibodies in serum and in the culture medium of duodenal biopsy specimens. RESULTS: CD was diagnosed in 191 of the 273 patients. Sensitivity and specificity of the serum anti-endomysium (EmA) and anti-tTG assays were 83% and 85% and 99% and 95%, respective…

Relational tourism: challenges and capabilities

2010

The observed changes in the orientation of tourism demand, both in taste and in the needs and preferences of the tourist consumer, in the last three decades, have brought to the birth of new ways of interpreting the tourism phenomenon; among these we highlight Relational Tourism, a phenomenon that can be perceived as human-scale tourism, clearly based on territorial, cultural and environmental constraints that include travel formats such as rural tourism, cultural tourism, farm tourism, environmental tourism, outdoor activity tourism and many new ways, which have shown an important quantitative growth of Relational Tourism demand in Europe and internationally in the last decades, offering a…

Quantitation of Metal Ions in Archaeological Glass by Abrasive Stripping Square-Wave Voltammetry Using Graphite/Polyester Composite Electrodes

2003

A method for identifying Co, Cu, Sb, Sn, Fe, Zn, and Zr pigments in glasses using square-wave voltammetry as the detection mode is described. It is based on the abrasive attachment of glass microsamples to graphite/polyester composite electrodes. Sample amounts less than 1 μg are used allowing for the study of archaeological samples. In all cases well-defined anodic stripping peaks corresponding to the oxidation of metal deposits generated at potentials ranging from −0.6 to −1.6 V (vs. SCE) are obtained. This response is in agreement with that displayed by the corresponding metal oxides. Quantitative estimates of the relative population of metal ions in glasses are obtained from peak area m…

Embedded-atom calculations of Auger and x-ray photoemission shifts for metallic elements

1982

Change in self-consistent-field energy density-functional calculations are reported for Auger and core-level binding-energy shifts in sp-bonded metals. The basic model, atom in jellium vacancy, gives good agreement with experiment, especially in the Auger case. The chemical and relaxation contributions to the shifts are discussed, and the extra-atomic response is analyzed in detail, both in position and energy space. The adequacy of the "excited-atom" approach to the energy shifts is discussed. Peer reviewed

IT-Supported International Subsidiary Establishment Process for the Japanese Market: A Case Study on Finnish High Technology SMEs

2005

The large size of the Japanese IT market makes it attractive to and important for foreign high technology companies. However, the Japanese market is very challenging, highly competitive, and difficult to penetrate for foreign small and medium-sized enterprises (SMEs). Most SMEs fail to penetrate into the Japanese market effectively by using modern IT-tools in the international subsidiary establishment process. No earlier in-depth empirical research exists on the IT-supported international subsidiary establishment process for this market. This study investigated and analyzed how a Finnish high technology SME implemented the ITsupported international subsidiary establishment process for the J…

Perceptions about Boards in Sme Sized Family Businesses

2009

This paper reports on a study of the attitudes to the formation and roles of formalised active boards in Australian small to medium sized (SME) family businesses. While the literature on governance includes guidelines for effective boards, many family owned businesses perceive they are functioning adequately without formalising a board structure. This study employed a qualitative approach and explored the board functions of nine family business cases drawing on the Hilmer and Tricker (1994) framework. This framework summarises the roles of boards as: formulating strategy, setting policies, supervising executive management and providing accountability. Cases included those with and without a…
