In the majority of large cities in Poland there is a migration outflow, resulting mainly from suburbanisation processes. However, it should be noted that the inhabitants of large cities do not move exclusively to the suburban zone. The study below focuses on the migratory outflow of Wrocław residents. The authors characterise it by presenting the directions of population movements and determining their sustainability. The authors conclude that the target area of immigrants from Wrocław is mostly a suburban area, but there are also permanent migration flows to other rural communities in the voivodeship and other large cities in the country. The area of emigration itself goes beyond the scope of the voivodeship of which Wrocław is the capital.

“…The need to reduce waste and the development of recycling technology in the metallurgical and foundry industries allow for economic reuse of slags from the refining processes of steel, copper and aluminium alloys as one of the many components of synthetic slags, backfills used in the metallurgical industry or, due to the high strength and low water absorption rate, as a component applicable in road construction [1][2][3][4][5][6][7]. Slags from metallurgical processes are transported in large-volume ladles made of cast iron (e.g.…”

“…The chemical composition of the slag depends on the type of alloy melted and on the melting technology currently used. Steel slags contain mainly oxides such as Sio 2 , Al 2 o 3 , Feo, Mno and remnants of melted alloy [5][6]. A common practice is to pour a new batch of slag into the ladle filled with the previously formed liquid slag, which creates temperature gradients between different parts of the ladle (flange, bottom and half of the ladle height), and additionally in the thermal nodes and casting wall cross-section [11,12].…”

The results of tests and examinations of the microstructure and mechanical properties of cast steel used for large-size slag ladles are presented. Castings of this type (especially large-size ladles with a capacity of up to 16 m 3 ) operate under very demanding conditions resulting from the repeated cycles of filling and emptying the ladle with liquid slag at a temperature exceeding even 1600°C. The changes in operating temperature cause faster degradation and wear of slag ladle castings, mainly due to thermal fatigue.The tests carried out on samples taken from different parts/areas of the ladle (flange, bottom and half-height) showed significant differences in the microstructure of the flange and bottom part as compared to the microstructure obtained at half-height of the ladle wall. The flange and bottom were characterized by a ferritic-pearlitic microstructure, while the microstructure at the ladle half-height consisted of a ferritic matrix, cementite and graphite precipitates. Changes in microstructure affected the mechanical properties. Based on the test results it was found that both the flange and the bottom of the ladle had higher mechanical properties, i.e. uTS, YS, hardness, and impact energy than the centre of the ladle wall. Fractography showed the mixed character of fractures with the predominance of brittle fracture. Microporosity and clusters of non-metallic inclusions were also found in the fractures of samples characterized by low properties.

Jedną z ważniejszych cech małych miast jest zróżnicowana sytuacja demograficzna. W dobie globalnych przemian w zakresie ruchu naturalnego najważniejszą determinantą kształtującą liczbę ludności w miastach stają się ruchy wędrówkowe, które w małych jednostkach w zależności od położenia mogą zachodzić z różną intensywnością. Celem opracowania jest charakterystyka migracyjna małych miast w województwie dolnośląskim i ich typologia w zakresie aktywności migracyjnej na podstawie charakterystyk odnoszących się do migracji, które dostępne są w statystyce publicznej. Opracowanie skupia uwagęnie tylko na analizie parametrów migracyjnych odnoszących się nie tylko do małych miast w analizowanym obszarze, ale też do ich zmienności w zależności od bliskości innych ośrodków miejskich.
