An Assessment of Land Use/Cover Suitable for Peri-urban Green Space Development: an Example of an Integration of GIS with the Multi-Criteria Analysis (MCA) Approach

Land allocation priorities to urban green cover are usually neglected particularly in the countries of developing economies such as Turkey. Lack of urban green space can cause many social and physical problems among the residents. Therefore, urban planning and policy should incorporate suitable green land in the urban planning of cities to optimise the benefits obtained from urban green spaces. Land suitability analysis is a commonly used methodology which provides a framework for developing strategies in the planning of green land development. Two different approaches will be utilised for the assessment of suitability of land uses for urban agriculture, forest and natural vegetation in the Pendik district of Istanbul. Standardisation of values in criteria maps was done using the deterministic approach in the first case whereas fuzzy membership was utilised as an alternative in the second case. Analytical Hierarchical Process (AHP) was used for the weighting of sub-criteria and map layers were overlaid using the weighted linear combination using the GIS software. Geophysical factors, transport and services accessibility, land cover/use, blue and green amenities, soil properties, geology and erosion susceptibility are the main criteria selected for the assessment of urban green land suitability. The provision of suitable land for urban agriculture, forest and natural vegetation uses will provide a framework to the land use planning and decision support aimed at contributing to urban sustainable development

Correlation between the visibility of submandibular fossa and mandibular canal cortication on panoramic radiographs and submandibular fossa depth on CBCT

To identify a correlation between the submandibular fossa (SF) visibility and mandibular canal (MC) cortication on panoramic image and the depth of SF measured on CBCT and also correlation between the depth of SF and vertical and horizontal location of MC on CBCT. 500 CBCT scans and panoramic radiographs were evaluated. SF depth types were classified as type I ( 3mm) on CBCT. Visibility of SF and the cortication of MC on panoramic radiographs were compared with the depth of SF on CBCT. Distances between MC and mandibular inferior, buccal and lingual cortices were measured. No statistically significant correlation was found between radiolucent appearances of SF, cortication of MC, and depth of SF. The deepest part of the fossa was in the second molar area followed by third and first molars. Negative weak correlations were found between B-MC, L-MC distances and depth of SF. Visibility of SF and cortication of MC on panoramic radiographs did not correlate with the depth of SF. A marked radiolucent submandibular fossa on panoramic image does not undoubtedly indicate a deep fossa, which emphasizes the importance of 3-D imaging in implant planning

Direct and Indirect Land Use Impacts of the EU Cohesion Policy. Assessment with the Land Use Modelling Platform

The Cohesion policy for the programming period 2014-2020 is analyzed in terms of its likely land use and environmental impacts using the Land Use Modelling Platform (LUMP). This report describes in detail the process and the methodology by which the ex-ante impact assessment was made, and presents the results for Austria, Czech Republic, Germany, and Poland. The modelling approach can provide insights on the trade-offs between economic growth, investment policies (such as the Cohesion policy), and land use and the environment. In addition, ways to mitigate potentially negative land use and environmental impacts were explored. The future development of the LUMP is discussed in view of planned future work.JRC.H.8-Sustainability Assessmen

On forward secrecy in one-round key exchange

Most one-round key exchange protocols provide only weak forward secrecy at best. Furthermore, one-round protocols with strong forward secrecy often break badly when faced with an adversary who can obtain ephemeral keys. We provide a characterisation of how strong forward secrecy can be achieved in one-round key exchange. Moreover, we show that protocols exist which provide strong forward secrecy and remain secure with weak forward secrecy even when the adversary is allowed to obtain ephemeral keys. We provide a compiler to achieve this for any existing secure protocol with weak forward secrecy

Dynamic spillovers between cryptocurrency and stock markets and their portfolio implications: Evidence from Turkey

The dataset of the study includes the daily closing prices of Bitcoin (BTC), three altcoins Ethereum (ETH), Ripple (XRP), Litecoin (LTC) and Borsa Istanbul Stock Exchange 100 Index (BIST100) between August 07, 2015 and May 20, 2021. All data are in US dollars. The cryptocurrencies and the BIST100, respectively, were obtained from www.coinmarketcap.com and The Central Bank of the Republic of Turkey database (https://evds2.tcmb.gov.tr/)

Effects of azithromycin versus metronidazole– amoxicillin combination as an adjunct to nonsurgical periodontal therapy of generalized aggressive periodontitis

Objective: This study evaluated the short‑term clinical benefits of two systemic antibiotic regimes added to the nonsurgical periodontal treatment of generalized aggressive periodontitis.Materials and Methods: The patient records were reviewed and 45 patients were selected and divided into the following three groups: Scaling and root planning (SRP) only; SRP plus azithromycin (AZT group); and SRP plus metronidazole and amoxicillin (M + A group). The periodontal indexes were recorded at baseline and 3‑month posttherapy.Results: The periodontal parameters were improved in all groups 3‑month posttherapy. The scores were decreased more in the AZT and M + A groups than the controls, but this difference did not reach significance. In addition, the decrease in the plaque index from baseline to 3‑month in the AZT group was not significant.Conclusion: Nonsurgical therapy reduces the probing depth, clinical attachment level, and clinical inflammation findings. This healing tendency was observed in the AZT group despite the baseline plaque scores. Therefore, AZT might be active against the bacteria in dental biofilms.Keywords: Azithromycin, generalized aggressive periodontitis, metronidazole and amoxicillin, nonsurgical periodontal therapy, scaling and root plannin
