Initial strain effects in multilayer composite laminates

2001

A boundary integral formulation for the analysis of stress fields induced in composite laminates by initial strains, such as may be due to temperature changes and moisture absorption is presented. The study is formulated on the basis of the theory of generalized orthotropic thermo-elasticity and the governing integral equations are directly deduced through the generalized reciprocity theorem. A suitable expression of the problem fundamental solutions is given for use in computations. The resulting linear system of algebraic equations is obtained by the boundary element method and stress interlaminar distributions in the boundary-layer are calculated by using a boundary only discretization. …

Foreign Market Entry Mode Research: A Review and Research Agenda

2017

ABSTRACTThis article gives a retrospective look at the main determinants of foreign market entry modes and examines the variables and conditions used in empirical studies in this stream of research. We found that there is an “analytical context hazard” in past studies. The findings suggest: first, future research should focus on developing and extending theories with reference to strategy dimension and market/industry environment; second, the interrelationship between the main entry mode determinants should be figured out; third, attention has to be paid to the entry modes of firms from non-developed economies in research.

Pros and cons of family policies for mothers' labour market participation

2012

PurposeThe purpose of this editorial is to examine sociological research on the possibilities and pitfalls of social policies for mothers' employment participation, and identify research gaps in the existing literature. The paper aims to focus mainly on the implications of parental leave schemes on mothers' employment participation.Design/methodology/approachThe editorial discusses the inconsistencies in the current sociological debate on the impact of social policies on mothers' employment.FindingsThe relationship between parental leave policies and women's participation in the work force is complex. The literature shows a disagreement about whether such policies mitigate family‐related ca…

ISomerization of xylene: MINDO/3 study of the cyclization of benzenium cation into bicyclo[3.1.0]hexenyl cation

1989

Abstract A MINDO/3 study of thermal electrocyclic closing of the benzenium cation to form a bicyclo[3.1.0]hexenyl cation is presented. The calculated mechanism discusses the possibility of cyclization of xylenium cations on a silica catalyst or in superacid media. The structure and energy of the transition state, the enthalpies of isomerization and barriers of activation were calculated for the following processes: isomerization of 2,6-dimethylbenzenium cation into 2,6-dimethylbicyclo[3.1.0]hexenyl cation, isomerization of 2,4-dimethylbenzenium cation into 2,4-dimethylbicyclo[3.1.0]-hexenyl cation, and isomerization of benzenium cation into bicyclo[3.1.0]-hexenyl cation. Equilibrium and kin…

O Futuro da Saúde / Aptidão Física / Desempenho Esportivo

2017

O exercício relativo à saúde / aptidão física e desempenho esportivo tem mostrado um papel evolutivo ao longo do tempo. São apresentados fatores primários de grande escala, que provavelmente nos ajudarão a entender o caminho evolutivo futuro da saúde / aptidão física e desempenho esportivo. Esses fatores incluem: 1) a história do exercício, 2) o exercício em sua relação com a saúde, 3) a necessidade de aptidão física entre os militares e os socorristas, 4) a relação conflitante entre o esporte (representando o ápice da capacidade genômica humana para o exercício) versus a natureza excessivamente competitiva e compensada do esporte. Predominantemente, a necessidade de exercício como medicina…

Talis pater, talis filius: the role of discursive strategies, thematic narratives and ideology in Cosa Nostra

2018

The discursive analysis of criminal organizations’ family dynamics and ideological devices may provide important insights into the inner functioning of these groups. In this article, we describe and analyze a specific set of discursive strategies and the thematic narratives emerging from a TV interview with Giuseppe Riina, a member of Cosa Nostra and the son of one of the most important mafia bosses. Our analyses demonstrate the existence of recurring ideological devices such as reductionism, amoralism, familism, verticalism, normalism, victimism and religious relativism. The results are discussed in light of previous research that examines how discursive strategies and narratives may repre…

Determination of90Sr in environmental samples with resonance ionization spectroscopy in collinear geometry

1994

A new, fast technique for trace analysis of the radioactive isotopes89Sr and90Sr in environmental samples has been developed. Conventional mass separation is combined with resonance ionization spectroscopy in collinear geometry, which provides high selectivity and sensitivity. In addition, a chemical separation procedure for sample preparation has been developed. The described technique was used to determine the90Sr content in ≈ 870 m3 air samples collected near Munich during and shortly after the Chernobyl reactor accident in April 1986. The content of90Sr was measured to be 1.4 mBq per m3, corresponding to 1.6 × 109 atoms of90Sr per sample. This value is in good agreement with the results…

Is Inequality Harmful for North-South Intra-Industry Trade Growth?

European phenological response to climate change matches the warming pattern

2006

Global climate change impacts can already be tracked in many physical and biological systems; in particular, terrestrial ecosystems provide a consistent picture of observed changes. One of the preferred indicators is phenology, the science of natural recurring events, as their recorded dates provide a high-temporal resolution of ongoing changes. Thus, numerous analyses have demonstrated an earlier onset of spring events for mid and higher latitudes and a lengthening of the growing season. However, published single-site or single-species studies are particularly open to suspicion of being biased towards predominantly reporting climate change-induced impacts. No comprehensive study or meta-an…
