Relationship between dental health and 10-year mortality in a cohort of community-dwelling elderly people

2003

Dental examinations were carried out as part of the Evergreen project, which focuses on functional capacity and health among the elderly residents of the city of Jyvaskyla, central Finland. Dental status was examined in 1990 for the whole population born in 1910 (n = 226). Mortality data were collected over 10 yr. The aim of the study was to assess the possible role of dental health as a predictor of mortality. The Kaplan-Meier method was used to analyse survival curves and Cox regression models, with the number of chronic conditions and self-rated health used as covariates in analysing the risks of death. The results showed that the more teeth or filled teeth a subject had, the smaller was…

Work ability in midlife as a predictor of mortality and disability in later life: a 28-year prospective follow-up study.

2011

Background: Poor work ability correlates with increased morbidity and early retirement from the workforce, but the association in old age is not known. We investigated work ability in midlife among white-collar and blue-collar employees as a predictor of mortality and disability 28 years later. Methods: A total of 5971 occupationally active people aged 44–58 years participated in the Finnish Longitudinal Study of Municipal Employees (FLAME) in 1981. Perceived work ability relative to lifetime best was categorized as excellent, moderate or poor. In 2009, the ability to perform activities of daily living was assessed among 2879 respondents (71.0% of the survivors). Mortality data were availab…

Make It or Break It: The Break-Through Rule as a Break-Through for the European Takeover Directive?

2003

The break-through concept is the most recent idea to break the deadlock with respect to EU takeover legislation. As devised by the High-Level Group of Company Law Experts, chaired by the Dutch Jaap Winter, the break-through concept would do away with two of the most important types of impediments to takeovers within EU member states. The first part of the paper explores the break-through concept in some detail, particularly with respect to its premises, its two guiding principles - exclusive shareholder decisionmaking and proportionality, - and the justifications given by the Group for the proposed interventionist rules. The second part of the paper is dedicated to an analysis of the econom…

Testing for goodness rather than lack of fit of an X–chromosomal SNP to the Hardy-Weinberg model

2019

The problem of checking the genotype distribution obtained for some diallelic marker for compatibility with the Hardy-Weinberg equilibrium (HWE) condition arises also for loci on the X chromosome. The possible genotypes depend on the sex of the individual in this case: for females, the genotype distribution is trinomial, as in the case of an autosomal locus, whereas a binomial proportion is observed for males. Like in genetic association studies with autosomal SNPs, interest is typically in establishing approximate compatibility of the observed genotype frequencies with HWE. This requires to replace traditional methods tailored for detecting lack of fit to the model with an equivalence test…

Relations between the cohesive energy, atomic volume, bulk modulus and sound velocity in metals

2011

By analysing the experimental data available in the literature, it has been found that the bulk modulus B of metals is proportional to the cohesive energy density Ec/V. For metals which start to melt having the close packed structure A1 or A3 the proportionality factor in the forementioned correlation is distinctly greater than that for metals melting from the A2 type structure. The existence of the correlation between the bulk modulus and the cohesive energy density leads to another, hitherto unrevealed correlation between the sound velocity, cohesive energy and the molar mass of metals: u2 ~ Ec/μ.

Electrochemical Monitoring of Compartmentalization Effects in the Stability of Meisenheimer Anions Supported in Hydrotalcite and X and Y Zeolites

2005

Meisenheimer anions (MS - ) derived from 2,4-dinitroaniline are stabilized into Li + - and Na + -exchanged zeolites X and Y forming alkali ion-MS ion pairs. Upon attachment of the zeolites to polymer film electrodes immersedinto Et 4 N + /MeCN and Li + /MeCN electrolytes, boundary-associated MS - ions display two oxidation processes at +0.40 and +0.65 V vs. AgCl/Ag. This response sharply contrasts with that recorded for MS - in solution and incorporated within hydrotalcite, for which a unique oxidation peak at +0.35 V is recorded. The electrochemistry of zeolite-associated MS - can be described in terms of an unusual electron-transfer/ chemical reaction/electron-transfer/comproportionation …

Does the interaction between the accounting method choice and disclosure affect financial analysts’ information environment? The case of joint ventur…

2017

IAS 31 allowed firms to choose between proportionate consolidation and the equity method to record joint ventures in the consolidated accounts of the venturer. Moreover, this election implied a decision about including information in the primary financial statements or in the notes. This paper investigates if financial analysts perceive accounting information differently depending on the method chosen conditioned to the disclosure of the required information in the notes. We analysed a sample of Spanish firms during 2005–2010. We not only considered earnings forecasts, but also examined target prices and stock recommendations. Furthemore, we look at how this accounting choice affects analys…

Zinn—Chalkogen-heterocyclen

1980

Abstract The preparation of a new six-membered ring compound (CH 3 ) 8 Sn 4 Te 2 containing two SnSn bonds isolated by Te is described and its structure established by means of analytical vibrational and NMR spectroscopic data. The well crystallizing yellow compound undergoes light-induced disproportionation reactions showing the generation of dimethylstannylene, which can be trapped either by CH 3 I or by the parent compound itself. In the latter case the reaction leads to five-membered rings with Sn 3 Te 2 - and Sn 4 Te-skeletons, respectively.

Imidotungsten(VI) complexes with chelating amino and imino phenolates

2011

The reaction of WOCl(4) with 2,4-di-tert-butyl-6-((isopropylamino)methyl)phenol followed by the reaction with phenyl isocyanate leads to the formation of imidotungsten(VI) complex [W(NPh)Cl(3)(OC(6)H(3)(CH(2)NH-i-Pr)-2-t-Bu(2)-4,6)] 4 with a chelating aminophenolate ligand. When the same procedure was applied using aminophenols with bulkier substituents in the amino group, the final product was an unexpected Schiff-base complex [W(NPh)Cl(3)(OC(6)H(3)(CH=NPh)-2-t-Bu(2)-4,6)] 5, where the ligand is derived from 2,4-di-tert-butyl-6-((phenylimino)methyl)phenol. Complex 5 is also formed in the thermal degradation of 4. On the whole, 5 appears to be formed by a disproportionation of intermediate …
