[Thanks to the courtesy of the Association of Education Committees we are able to print Mr. W. Popplestone's Memorandum on the Education of Children of Combined Defect, which was forwarded by the Association to the Board of Education. In our January issue we published a letter on this subject from Mr. Popplestone, who is the Director of Education for Shipley, Yorkshire, and readers may recollec...

The need to restructure, redesign or develop a management model on scientific basis at domestic petrochemical enterprises in the context of challenges industry 4.0 and prospects 5.0, transition new standards, lack qualified managers determine importance relevance problem choosing optimal organizational structure enterprise that contributes most effective achievement goals. When designing evalua...

We investigated the homeostatic behavior of hematopoietic stem and progenitor cells (HSPCs) temporally defined according to their divisional histories using an HSPC-specific GFP label-retaining system. We show that homeostatic hematopoietic stem cells (HSCs) lose repopulating potential after limited cell divisions. Once HSCs exit dormancy and accrue divisions, they also progressively lose the a...

The North American model of resource allocation in professional sports leagues is adapted for English (association) football. The theoretical relationship between revenue and competitive balance is shown to be robust with respect to changes in teams’ objectives and labour market conditions. Empirical revenue functions are reported for 1926-1999. These indicate a shift in the composition of dema...

traditional dea models deal with measurements of relative eciency ofdmus regarding multiple - inputs vs. multiple-outputs. one of the drawbacksof these model is the neglect of intermediate products or linkong activities. af-ter pointing out needs for inclusion of them to dea models. we propose hybridmodel that can deal with intermediate products formally using this model wecan evaluate divisio...

The response of solid and liquid targets to rapid heating by the incident proton beam is assessed in a classical way, among other things by solving the wave equation under linear conditions and in cylindrical symmetry. This study provides bench mark values and allows to identify critical issues and limiting factors which can help to guide further investigations with more sophisticated means. CE...

Continuing developments in homodyne laser interferometer systems [1] are improving both their measurement performance capability and their ease of installation. This paper gives an overview of such a system and explains several of the key design features. Firstly, an overview of the optical detection scheme is given. Secondly, a novel method for improving the Sub Divisional Error (SDE) in a Col...
