Bu çalışmada, Afyonkarahisar organize sanayi bölgesinden temin edilen parça mermer atıklarının "TS 706 EN 12620 + A1 "Beton Agregaları" standardına uygunluğu araştırılmıştır. Atık sahasından alınan parça numuneler standartlarda belirtilen boyutlara getirilerek fiziksel, kimyasal ve yaşlandırma testlere tabi tutuldular. Yapılan testler sonucunda mermer parça atıklarından elde edilen agregaların "TS 706 EN 12620 + A1 "Beton Agregaları" standartlarında aranan alt ve üst sınırlar içinde olduğu ve atıklardan elde edilen agregaların hazır betonda beton agregası olarak kullanılabileceği sonucuna varılmıştır.

Why do seemingly similar political parties adopt different positions on the same issue? We answer this question by studying different approaches of dominant nationalist parties to Syrian refugees in Turkey under the new presidential system. Drawing on an original Twitter dataset and party manifestos, we argue that new electoral dynamics and the rise of urban-liberal nationalism as an alternative to rural-conservative nationalism have contributed to the divergence in nationalist parties’ approaches to refugees in recent years. The findings of this paper are threefold. First, pre-electoral alliance loyalties constrain nationalist parties’ discourses about refugees. Second, when the electoral salience of refugee issues increases, the convergence between dominant pre-electoral alliances’ positions might motivate a strategic opening/niche in the political space. Third, urbanization leads to the rise of contradictory forms of nationalism in cities: civic-liberal and ethnic-nativist, affecting the discursive strategies of nationalist party elites toward immigrants and refugees.
