Mekansal ideolojilerin haritalanması: Hekimhan maden yerleşkesi örneği, Malatya.

This thesis follows the spatial traces of iron mining in Hekimhan district of Malatya, aiming to make its dialectical relationship to the history of political-economy of Turkey and ideological framework visible. Within this scope, it examines how the iron and steel industry has been linked to political-economic relations throughout the history of the Republic and approaches ideological superstructure elements regarding their reflections on space. By focusing on social facilities of the Hekimhan Mining Institutions, it seeks the results of the establishment process corresponding to the neoliberal transformation processes taking place after 1980. While trying to reveal complex relations implicit in the case study area, it aims to visualize the overlapping of the space with its socio-political background through conceptual mapping. By doing this, the study examines the potential of mapping to associate the physical with the conceptual and ultimately, aims to open up new discussions about the collective production process and the limits of the production of space through the current state of the case studies area.Thesis (M.Arch.) -- Graduate School of Natural and Applied Sciences.

Separating the scales in a compressible interstellar medium

We apply Gaussian smoothing to obtain mean density, velocity, magnetic and energy density fields in simulations of the interstellar medium based on three-dimensional magnetohydrodynamic equations in a shearing box $1\times1\times2 \, \rm{kpc}$ in size. Unlike alternative averaging procedures, such as horizontal averaging, Gaussian smoothing retains the three-dimensional structure of the mean fields. Although Gaussian smoothing does not obey the Reynolds rules of averaging, physically meaningful central statistical moments are defined as suggested by Germano (1992). We discuss methods to identify an optimal smoothing scale $\ell$ and the effects of this choice on the results. From spectral analysis of the magnetic, density and velocity fields, we find a suitable smoothing length for all three fields, of $\ell \approx 75 \, \rm{pc}$. We discuss the properties of third-order statistical moments in fluctuations of kinetic energy density in compressible flows and suggest their physical interpretation. The mean magnetic field, amplified by a mean-field dynamo, significantly alters the distribution of kinetic energy in space and between scales, reducing the magnitude of kinetic energy at intermediate scales. This intermediate-scale kinetic energy is a useful diagnostic of the importance of SN-driven outflows
