Abstract The present intention to reach fossil-free steel manufacturing will inevitably result in an increase the use of scrap as a raw material for production. Consequently, amounts elements, seen impurities, steels. This has already been electric arc furnace (EAF) processed steels, where Cu and Sn levels have doubled some cases after 1980’s. may cause problems, it is well-known, that impurity...

Over the last decade or so, labour market pressures and changes in the nature of public service provision have generated new issues for policy makers and practitioners related to the way in which public service employees are managed. The recruitment and retention difficulties associated with particular occupational groups have been seen to present a real threat to the level and quality public s...

It is proposed that by using computing analysis software and 3D fabrication techniques, low cost plastic trumpet bells could be produced for different music genres by altering their timbres. These may be attached to the trumpet in a similar manner to that of a tuning bell trumpet. The novel bells are designed to eliminate or enhance particular harmonics to change their brightness by altering th...

A metamodel definition presents some important issues in the construction of an object database management system, whose rich data model inevitably increases the metamodel complexity. The required features of an object database metamodel are investigated. Roles of a metamodel in an objectoriented database management system are presented and compared to the proposal defined in the ODMG standard ...

Geomagnetic activities frequently occur in varying degrees. Strong geomagnetic activities, which have been widely investigated, occasionally; they can cause distinguishable and significant disturbances the ionosphere. Weaker appear, whereas their effects are generally difficult to be distinguished from complex ionospheric variations. play important roles day-to-day variability thus should deser...

i Innovative forms of public participation challenge the idea that activists must inevitably be caught up in consultation methods that are tokenistic or manipulative. Citizens’ juries, consensus conferences, deliberative polls and televotes—these methods hold promise for enhanced representativeness and offer the added benefit of creating deliberative spaces for sound decision making. These robu...

As a cell source, multipotent mesenchymal stromal cells or mesenchymal stem cells (MSCs) are promising candidates for chondrogenic differentiation and subsequent cartilage regeneration. From previous literature, it is known that chondrogenic differentiation of MSCs inevitably leads to hypertrophy and subsequent endochondral ossification. In this review, we examine the history of currently estab...

in this study, the recovery of casing soil consumed in the white button mushroom was investigated. casing soil is used as a layer on compost (culture medium) to a diameter of 3-5to stimulate fruiting on the white button mushroom(agaricus bisporus) . the expense od casing soil is about 30 percent of production costs. in the first step of this experiment, in order to separate casing soil from com...
