Ion source and LEBT of KAHVELab proton beamline

The KAHVE Laboratory, at Bo\u{g}azi\c{c}i University, Istanbul, Turkey is home to an educational proton linac project. The proton beam will originate from a 20 keV H+ source and will be delivered to a two module Radio Frequency Quadrupole (RFQ) operating at 800 MHz via a low energy beam transport (LEBT) line. Currently, the design phase being over, commissioning and stability tests are ongoing for the proton beamline which is already produced and installed except the RFQ which is being manufactured. This work summarizes the design, production and test phases of the ion source and LEBT line components

Direct measurement of the 19 F(p,α0 )16 O reaction at Ecm = 0.4–0.9 MeV using the LHASA detector array

5 pags., 6 figs., 1 tab.The 19F(p,α)16O reaction is of paramount importance for understanding the fluorine abundance in the outer layers of asymptotic giant branch (AGB) stars and it might also play a role in hydrogen-deficient post-AGB star nucleosynthesis. Theoretical models overestimate F abundances in AGB stars with respect to the observed values, thus calling for further investigation of the reactions involved in the fluorine nucleosynthesis. In the last years, new direct and indirect measurements improved significantly the knowledge of the 19F(p,α)16O cross section at deeply sub-Coulomb energies (below 0.8 MeV). Those data are larger by a factor of about 1.4 with respect to the previous data reported in the NACRE compilation in the energy region 0.6–0.8 MeV. In order to solve these discrepancies, here we present a new direct experiment performed using a silicon strip detector array (LHASA – Large High-resolution Array of Silicon for Astrophysics). Our results clearly confirm the trend of the latest experimental data in the energy region of interest, pointing towards a larger S-factor value than the one reported in the NACRE compilation.This work was partially supported by the Extreme Light Infrastructure Nuclear Physics Phase II, a project cofinanced by the Romanian Government and the European Union through the European Regional Development Fund – the Competitiveness Operational Programm (1/07.07.16, COP, ID1334), by ENSAR2, a project financed by the European Union’s Horizon 2020 research and innovation programm under grant agreement No. 654002 and by the funds DGAPAUNAM IN107820 and CONACyT 315839.

Linkages among ecotourism, landscape and natural resource management, and livelihood diversification in the region of Sugla Lake, Turkey

The purpose of this study is to evaluate opportunities of the region of Sula Lake located in Turkey for community-based ecotourism development that enable sustainable landscape and natural resource management as well as livelihood diversification. A participatory research approach was applied by participation of a diverse number of stakeholders (e.g. local communities, local and central governmental bodies and researchers). A set of participatory research tools (e.g. interviews and field surveys), SWOT analysis and the method of Ecotourism Opportunity Spectrum (ECOS) were used to collect and evaluate relevant data. The study consists of four sections. The first section focuses on SWOT analysis by which the advantages and disadvantages of the study area for ecotourism development were examined. In the second section, the most suitable villages for ecotourism development were examined by adapting the method of ECOS based on the 18 parameters by using 1-4 score system. Accordingly, the most suitable five villages for ecotourism development were determined. Major natural and cultural ecotourism resources (e.g. diversity of landforms, spectacular landscapes and traditional lifestyle) of the study area were examined in the third section. In the fourth section, the ecotourism-based livelihood and relevant core capitals were evaluated according to 1-4 score system for the five villages. We hope that the outcomes of this study can draw attention of planners and policymakers to the role of ecotourism for sustainable landscape and natural resource management as well as livelihood diversification in the region and elsewhere

Hegemonic Masculinity in Times of Crisis: 15 July Coup Attempt and the Turkish Football

In the evening of 15 July 2016, Turkey was shaken to its pieces by an unexpected yet abortive coup attempt. Just like the previous ones, this recent attempt to stage a coup had a substantial impact on various social and cultural realms including football. By developing a holistic approach to the notion of hegemonic masculinity (a concept coined by R. Connell) and assessing the interplay of hegemonic masculinity in the realm of ideology, state institutions and military on the one hand and that on football pitches on the other hand in their relationality, this chapter argues that the climate culminating around the attempted coup in Turkey witnessed an intense display of the already existing hegemonic masculinity structures, including those which could be seen in Turkish football
