Magnetostructural Relationships For Fe(III) Spin Crossover Complexes

Abstract

Structural data for fifteen complexes of Fe(III) of a general formula [FeL5X], with pentadentate Schiff-base ligands L5 and unidentate coligands X, were subjected to a statistical analysis. The multivariate methods such as Pearson correlation, cluster analysis and principal component analysis split the data into two clusters depending upon the low-spin and/or high-spin state of the complex at the temperature of the X-ray experiment. Some of these complexes exhibit a thermally induced spin crossover. The numerical analysis of the magnetic susceptibility and magnetization data for an enlarged set of Fe(III) spin crossover systems yields the enthalpy ΔH and entropy ΔS of the transition along with the transition temperature T 1/2 and the solid state cooperativeness. The thermodynamic data show a mutual relationship manifesting itself by linear ΔS vs ΔH and T 1/2 vs ΔH correlations.

Magnetic field of the Western Carpathians (Slovakia): reflections on the structure of the crust

Magnetic field of the Western Carpathians (Slovakia): reflections on the structure of the crust

A new digital magnetic map of Slovakia on the scale of 1: 200,000 and 1: 500,000 was compiled at the end of 2008 as the output of database magnetic objects from the whole territory of Slovakia at a scale of 1: 50,000. The variable geological structure of the West Carpathian crust is depicted in the equally variable magnetic field of this region. A sizable number of magnetic anomalies with manifold character have been recognized. The basic anomalies distribution was divided into two groups: anomalies connected with rocks of the pre-Neogene basement and anomalies which originate in Neogene and Quaternary volcanic products. Most of the significant anomalies in the pre-Neogene basement were interpreted, modelled and consequently its geological and tectonic classification was worked out. On the basis of the anomalous field features, the following sources of anomalies have been distinguished: a) known, located on the surface, or at shallow depths verified by boreholes, mainly expressed by simple morphology, b) deep-seated and expressed by complicated morphology, reinterpreted or newly interpreted and also problematic. According to our present knowledge the interpretations are insufficient and remain open for further investigation. The above mentioned sources of magnetic anomalies are classified in terms of tectonic provenience to the main tectonic units.

Age Discrimination, Release of Employees and Sustainable Law Strategy in Industrial Enterprises

Abstract

The implementation of new trends into industrial practice as well as the influence of various external and internal factors affects the operation of industrial enterprises and their performance. Industrial enterprises that have developed a sustainable human resource management strategy are able to resist negative impacts. A sustainable law strategy defines the range of options for the implementation of a sustainable human resources management strategy. A sustainable law strategy, as a base of business strategy is affecting other strategies in industrial enterprises and also it provides a framework for business sustainability as part of an ecosystem in sustainable corporate social responsibility strategy. The importance of the consistency of mentioned strategies is contained in the presented paper. Consistency of strategies ensures fair treatment of employees as a key internal factor in business success. It is important that employers treat their employees fairly, especially in the case of negative measures. The main aim of the paper is to present results of the research focused on identified discrimination and release of employees in industrial enterprises. The research sample consisted of n = 692 respondents composed of industrial enterprises employees. Among the significant results, the authors of the paper advise the finding, that a significant part of the respondents did not encounter age discrimination. The conclusion contains recommendations for the development of sustainable law strategy regarding to findings related to the release of employees and age discrimination.
