    (Izmir Institute of Technology, 2022) Hajatnia, Haniyeh; Ökten, Hatice Eser; Ökten, Hatice Eser; 03.07. Department of Environmental Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Global solid waste generation is constantly rising, hence the need for management strategies that implement environmental improvements. The sustainable municipal solid waste management strategy for municipalities must include collection and transportation. The collection and transportation sector have been neglected while it is one of the most significant polluters. As a result, this study aims to model municipal solid waste transportation using Life Cycle Assessment (LCA) software which we used CCalC2 for this study and CML2001 methodology was used. To demonstrate how different approaches to waste management through transportation can reduce environmental impacts, LCA modeling was done for the three districts of Urla, Çeşme, and Karaburun, all of which are located on the Karaburun Peninsula. Each district was assigned three scenarios, with Scenario 0 representing current municipal practices, Scenario 1 representing a 50% reduction in plastic waste, and Scenario 2 representing a 50% reduction in all renewables. Results showed that only plastic separation might not be enough to achieve significant e reductions in environmental impacts. It has been demonstrated that in the transportation sector of Urla and Çeşme, Scenario 1 had a CO2 reduction of 3.7% and Karaburun had a CO2 reduction of 3.8% while Scenario 2 represented at least a 20% reduction of carbon footprint in all three districts. Findings of this research will support municipalities in the roadmaps they will choose for the Municipal Solid Waste Management applications.

    Phytochemical Studies on the Mastic Gum of Pistacia Lentiscus Var. Chia Collected From Karaburun Peninsula and Bioactivities of Isolates
    (01. Izmir Institute of Technology, 2021) Bedir, Erdal; Bedir, Erdal; Ballar Kırmızıbayrak, Petek; 03.01. Department of Bioengineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Pistacia lentiscus L. is an evergreen shrub or tree-like plant named as 'mastic tree'. The phytochemical studies of Chios mastic gum have revealed that it is a complex natural product comprising several organic ingredients like natural polymers, essential oils and triterpenic compounds. Triterpenes are the main components of mastic gum, and they are thought to be responsible for important biological activities such as anti-cancer, anti-ulcer, cytotoxic, antidiabetic, and anti-inflammatory. Within the scope of this thesis, mastic gum collected from the mastic trees (Pistacia lentiscus var. chia) grown on the Karaburun peninsula of İzmir was investigated to reveal its phytochemical composition and neuroprotective effects of the isolates. Isolation and purification studies utilizing chromatographic methods are followed by structural elucidation of the isolates by spectroscopic methods (1D NMR, 2D NMR, MS and X-RAY). Detailed analysis of the obtained spectra helped us to establish structures of 14 molecules possessing triterpenic skeleton, and two of them turned out to be undescribed compounds. The bioactivity of selected compounds was screened for their neuroprotective effects against H2O2 induced oxidative stress on differentiated and undifferentiated SH-SY5Y cells. Two compounds showed neuroprotective effects against H2O2-induced cell death on undifferentiated SH-SY5Y cells at 5 and 10 µM concentrations, while the other compounds either showed little or no effect. This study provides promising new insights into the use of mastic gum or its components in the treatment of neurodegenerative diseases.

    Commodification of Nature and Accumulation by Dispossession in Karaburun Peninsula
    (Izmir Institute of Technology, 2019) Özcan Cive, Yağmur; Avar, Adile; Avar, Adile; 02.03. Department of City and Regional Planning; 02. Faculty of Architecture; 01. Izmir Institute of Technology
    Biophysical areas and resources have been privatized, and subjected to market in response to requirements of the capital accumulation with the view of overcoming the crisis of capitalism in the 1970s. Natural areas previously untouched or used for local production have become “spatial fixes”, to which global capital switched, through state regulations. In other words, there has been an increasing intervention into natural areas, and occurred an intense form of commodification of nature. Privatization, commodification and marketization of these areas lead to environmental degrading. Besides, enclosure of these areas to prevent access of local people to use these natural sources causes them not to able to keep on their livelihood activities. Local people who have been taken away from their common lands or private properties by being deprived of use or ownership are becoming increasingly impoverished and dispossessed. Neoliberal practices after 2000 in the Karaburun Peninsula are striking examples of commodification of nature and accumulation by dispossession. This study examines neoliberal regulations, policies and practices, the overlap between the natural areas and investments, and ownership of these areas in Karaburun Peninsula. As a result, it is seen that the pasture areas used by the villagers to earn their living have been narrowed; their properties have been expropriated and then allocated for wind power generation and industrial olive cultivation. Moreover, the increase of mining investments, fish farms and secondary dwellings on state lands, agricultural lands, pastures and coastal areas have led to privatization of natural areas and restriction of local access.

    Construction Techniques of Traditional Houses in Karaburun Villages
    (Izmir Institute of Technology, 2019) Görür, Burçin; Kul Özdemir, Fatma Nurşen; 01. Izmir Institute of Technology
    This thesis aims to understand the building materials and construction techniques utilized in the traditional houses of the villages in Karaburun Peninsula; Küçükbahçe and Kösedere in particular. With this aim, a preliminary study is carried out in 13 historical villages of the Peninsula in order to understand their traditional building reservoir, preservation state of traditional buildings and materials and construction techniques. The results of the preliminary study showed that materials and techniques utilized are quite similar with slight differences between east and west zones of the Peninsula. Two villages, Küçükbahçe and Kösedere, that best represent these differences are selected from two zones. The traditional building reservoir in these two villages is further analyzed to understand materials and techniques applied in foundations, walls, floors, roofs and architectural elements. As conclusion, it is understood that hybrid construction system is used in both villages. The exterior walls are stone masonry; the inner walls are timber frame without infill. Although the system is similar, there are slight differences in materials choices. The stone material used in two villages differs in shape, size and color related with the source of the materials. This is related with different geological characteristics of east and west zones of the peninsula. Another difference observed in Küçükbahçe is the common use of reed instead of timber laths in timber frame walls. Timber flooring system is similar in both villages. The original flat roof system has slight differences related with the availability of materials. Reed is used instead of timber elements in Küçükbahçe. The soil type is also different. The soil type, that is called “geren” used in Küçükbahçe has higher clay content. The materials and technique of architectural elements are similar in both villages.

    Microbiological Characterization of 'hurma Olives Grown in Karaburun Peninsula
    (Izmir Institute of Technology, 2013) Karslı, Gözde Seval; Baysal, Ayşe Handan; Baysal, Ayşe Handan; 03.08. Department of Food Engineering; 03. Faculty of Engineering; 01. Izmir Institute of Technology
    Erkence variety olive (Olea europea L.) cultivar growing in the Aegean Region of Turkey is a naturally black olive. Debittered Erkence variety called "Hurma" olive is an unusual olive type which is characterized by the sweet taste of its fruit. This olive which is grown mainly in Karaburun Peninsula differs from other varieties since it ripens on the tree losing its bitterness caused by phenolic compounds especially oleuropein. Thus, Hurma olives can be directly consumed from the tree without a further debittering process to make them edible. Total aerobic mesophilic microorganisms, lactic acid bacteria (LAB), Enterobacteriacaae, Pseudomonadaceae, Staphylococcaceae-Micrococcaceae, moulds and yeasts were enumerated in the olive drupes, leaves and orchards' air of Erkence and Gemlik cultivars during the maturation period. Moreover, bacterial microflora of Hurma olive fruit, leaf and orchards' air were characterized in terms of DNA sequencing. Microbial loads of naturally debittered "Hurma" olive were higher when compared with Gemlik olive's and non-debittered Erkence variety olive's. But no Pseudomonadaceae, Staphylococcaceae-Micrococcaceae and LAB were detected in all samples. Bacterial microflora genera of Hurma olive comprised of Bacillus, Pantoea, Acinetobacter and Pseudomonas while the other samples have also similar bacterial genera. The common genus found in all samples was Bacillus. Besides, more diversified genera were obtained from phylloplane and air microflora of Erkence variety olive orchard was substantially similar to bacterial phylloplane of leaf. This is the first study about microbiological characterization of Hurma olive type and will lead up to new studies about it.
