Prediction of Deep Bright Spots via Gassmann Fluid Substitution and Seismic Amplitude Interpretation in the Vermilion Area, Northern Gulf of Mexico

The objective of this study is to investigate the deep bright spots observed in the Vermilion area, northern Gulf of Mexico, and assess whether they represent gas sand reservoirs. The study was carried out by Gassmann fluid substitution, seismic amplitude interpretation, and Reuss bound examinations of five study areas in the region. The Davy Jones gas discovery of the McMoRan Company at about 8700 m in South Marsh Island Block 230 (close to the Vermilion area) provided both the motivation and initial reservoir parameters for this study. Tertiary Wilcox sands are the primary reservoir targets of the study. The reservoir conditions of Davy Jones were simulated by coding Gassmann’s equations and Batzle’s relations in Matlab to study fluid effects and bright spot signatures. Based on reservoir response, the study areas were compared by fluid substitution analysis and seismic amplitude interpretation. Examination included reservoir response for brine and gas saturated velocities, reflection coefficients, and elastic parameters. Furthermore, Reuss bound studies of the areas were originated from brine-and gas-saturated P-wave moduli bounds of Davy Jones, and they increased the confidence of the reservoir response associated with each study area. Adjusted pore pressures, formation temperatures, and stiffness parameters were found to play a key role in characterizations of the areas. The study showed that three of the study areas (N1, N2, and N3) have probable gas bright spot responses, whereas two regions (N4 and N5) show amplitude anomalies inconsistent with gas bright spots.Earth and Atmospheric Sciences, Department o

INTRA-PARTY AUTOCRACY OF TURKEY’S PARTY SYSTEM

Democratic systems are unthinkable without political parties. Since its transition to multi-party politics in 1950, Turkey has enjoyed a stable yet limited level of stability in its multi-party system. Despite all the democratic experience in electoral politics for more than half a century, democracy exists only between, not within political parties in Turkey. The political culture of Turkey still tolerates one man-driven, charismatic leader parties administered with excessively centralized and authoritarian leadership structures. Turkey’s parties are still controlled mostly by men. What they differ is not the presence or absence of intra-party democracy, but their type of intra-party autocracy. This study explains the roots of party autocracy culture in Turkey’s parties. In doing so, it also develops a theoretical framework for comprehending and explaining intra-party democracy in democratic systems in general and in Turkey. It also specifies sociological, institutional and competitive criteria of intra-party democracy such as political culture, legal framework, preferences of individual actors as well as many others including gender quota, tolerance for dissent and the degree of power centralization

Kılıçdaroğlu’s CHP: What Lies Ahead?

The unexpected switch of the CHP’s leadership from Deniz Baykal to Kemal Kılıçdaroğlu led to a series of debates about the party’s political future and its new place in the party system of Turkey. Most of the debates have focused on what exactly changed and what remained the same as a result of this switch. Kılıçdaroğlu’s speeches revealed signs for new directions in CHP’s discourse indeed, as they included novel issues such as intra-party democracy and empowering the party’s women and youth branches. The purpose of this policy brief is to propose ideas to the CHP as a social democratic party, so it can be a serious political alternative to the conservative AK Party. The CHP’s major target should be democratization to be achieved at two different levels: (a) institutional and (b) ideological. Institutional democratization requires establishing intra-party democracy, decentralization of power, as well as bringing ideological heterogeneity and political debates back to the party. Ideological democratization is about bringing ‘the left’ back to Turkish politics by embracing a progressive and social democratic discourse. This entails moving leftwards, a de-emphasis of nationalism and the adoption of a more egalitarian, less elitist, more libertarian, and more multiculturalist world vision.From Baykal’s CHP to Kılıçdaroğlu’s CHPInstitutional DemocratizationIdeological DemocratizationConclusion and DiscussionPublisher's Versio

Deprem Yönetmeliği'nde Plastisite Teorisinin Uygulamaları

Konferans Bildirisi -- Teorik ve Uygulamalı Mekanik Türk Milli Komitesi, 2013Conference Paper -- Theoretical and Applied Mechanical Turkish National Committee, 2013Betonarme yapıların tasarım yönetmeliklerinde plastisite teorisinin bazı kavramları daha çok dolaylı olarak bulunur. Buna karşılık yapıların deprem güvenliğinin sağlanmasında kontrollünde hasar kabul edildiği için, deprem yönetmeliklerinde plastisite teorisinin değişik kavramları yaygın biçimde kullanılır. Deprem Yönetmeliği’nin daha önceki baskılarında bu kavramların dolaylı görülmesine rağmen, Deprem Yönetmeliği (2007) de plastisite teorisinin kavramları doğrudan kullanılmıştır. Günümüzde bu kavramlar uygulamadaki mühendisler tarafından yaygın bir şekilde, bazı durumlarda anlamı tam anlaşılmadan kullanılmaktadır. Bir yapının tasarımı veya deprem güvenliğinin belirlenmesi gibi karmaşık problemlerde ayrıntıya girilerek bu kavramların açıklanması ve anlaşılması çoğu zaman zordur. Bu yazıda Deprem Yönetmeliği (2007) de kullanılan plastisitenin bazı ana kavramlarının ayrıntıya girmeden açıklanmasını hedeflenmiştir.Various concepts of the theory of plasticity can be found often implicitly almost in all design codes for reinforced concrete structures; however, since often controlled damages are accepted in design of regular structures subjected to the design earthquake, concepts of the theory of plasticity are employed directly in seismic codes. Although the older versions of the Turkish Seismic Codes include these concepts indirectly, the Turkish Seismic Code (2007) contains them explicitly. These concepts are used more often than ever in Turkish civil engineering community sometimes without grasping their actual meaning. However, it is often difficult to go into details of these concepts to explain them, when a sophisticated problem, such as design and seismic evaluation of a complex structure, is involved. The present paper attempts to give the main plasticity concepts by using graphical representations without going into detail as they are considered in the Turkish Seismic Code (2007)

The repeat municipal elections of Istanbul, 2019: a new beginning for Istanbul and democracy in Turkey

The Istanbul repeat elections held on June 23, 2019 re-solidified the electoral defeat of the Justice and Development Party (AKP) in a major election. Earlier, the March 31, 2019 municipal election had already resulted surprisingly with the AKP’s loss of major provinces and metropolitan municipalities, Istanbul and Ankara in particular, to the main opposition Republican People’s Party (CHP) and its party-allies of the Nation Alliance. The CHP’s candidate Ekrem İmamoğlu won even more decisively this time, with more than 54% of Istanbul’s voters. These wins in the municipal and repeat-Istanbul elections provide an opportunity for a new democratic onset in Turkish politics. The CHP-led municipalities of Turkey in general, and the Istanbul municipality by İmamoğlu in particular, have the potential to become the driving force of a new wave of democratization in Turkey. This policy paper aims to lay out clearly some steps to be taken for that direction.Publisher's Versio

On the General Requirements for Design of Earthquake Resistant Buildings in The Turkish Building Seismic Code of 2018

Turkish Building Seismic Code has been revised after eleven years once more and its application is compulsory since the beginning of 2019. The new code is published together with a new Earthquake Hazard Map and it consists of 17 chapters. Some of the chapters have been revised thoroughly updated, whereas some new chapters are added as well. In the revision of the code, developments in the earthquake engineering and in the building technology are taken into consideration. Requirements related to ground motion are given in a separate chapter by defining four levels of earthquake motion. The code contains the strength design of the buildings as it is accustomed in the previous codes. However, performance based design is highlighted for high-rise buildings and for socially important buildings located moderate and high seismicity regions. The code has new separate chapters for high-rise buildings, coldformed steel buildings, timber buildings and seismically isolated buildings. Furthermore, it has a new chapter for non-structural elements as well. The chapters involving design of steel structures, seismic evaluation of the existing buildings, and structural and geotechnical design of foundations are revised significantly. The chapter on the design of reinforced concrete contains a limited modification as well. However, since most of the buildings are reinforced concrete, this chapter relatively is important. In the present paper, the general design and evaluation approach of the code presented in detail and comparatively by considering the previous Turkish Building Seismic Codes

Capire la Turchia al di là dei Pregiudizi

Turkey's recent foreign policy orientation has both been lauded and criticized. While some analysts argue that Turkey is on the way to become a regional power through its «multi-stakeholder» foreign policies, others suggest that the country is now sliding away from its EU membership course and pro-Western policy choices towards the «Islamic» camp, especially considering the recent tension with Israel and divergence from US's policy on Iran. This article aims to provide a more balanced picture through an examination of Turkey's history of domestic politics and foreign policy

Nanofibers in Cosmetics

Nanofibers form the broadest class of nanomaterials due to their unique properties. High surface-area-to-volume ratios, low diameters, high strength values, low basis weights, high porosities, and small pore sizes make them good candidates for numerous applications. Cosmetics are one of these important application areas. Excellent interaction with environment (e.g., skin or damaged tissue), increased loading capacity for agents, high liquid absorption capacities, high oxygen, and water vapor permeability values are provided by characteristic properties of nanofibers. They are used as therapeutics, facial masks, skin care, and renewal products. This chapter will provide an overview of nanofibers in cosmetics. A brief history of cosmetics, different types of nanomaterials used in cosmetics, nanofiber properties, and production methods are described in this chapter. Novel applications of nanofibers in cosmetics are also mentioned

Two new hybrid species of Salvia (S. x karamanensis and S. x doganii) from Turkey: evidence from molecular and morphological studies

Celep, Ferhat/0000-0003-3280-8373WOS:000596023100005Salvia L. is an ideal exemplar to demonstrate prezygotic isolation mechanisms in sympatric populations due to their well-known staminal lever mechanism. Mechanical, phenological, and ethological isolation mechanisms have been reported among sympatric species of Salvia. However, it has been shown that if closely related species are sympatric and flower at the same time, they can potentially hybridize. In this study, we describe two new hybrid species of Salvia (S. x karamanensis Celep & B.T.Drew, and S. x doganii Celep & B.T.Drew) from Turkey based on morphological and molecular evidence. Salvia x karamanensis (S. aucheri Benth. subsp. canescens (Boiss. & Heldr.) Celep, Kahraman & Dogan x S. heldreichiana Boiss. ex Benth.) is known from near Karaman city in the central Mediterranean region of Turkey, and S. x doganii (S. cyanescens Boiss. & Bal. x S. vermifolia Hedge & Hub.-Mor.) occurs near Sivas in central Anatolia, Turkey. Morphological comparisons between the hybrid species and their putative parents are given with notes on the International Union for Conservation of Nature (IUCN) red list categories, biogeography and ecology of the two hybrid species.TUBITAKBIDEB 2219 Postdoctoral Research ProgramTurkiye Bilimsel ve Teknolojik Arastirma Kurumu (TUBITAK); NSF-DEB grant [DEB-1655611]We thank Dr. Ricardo Kriebel (University of WisconsinMadison) for assistance with flower scans, Prof.Dr. Esra Martin (Necmettin Erbakan University) for information about chromosome numbers of S. vermifolia, and the curators of herbaria ADO, ANK, BM, E, G, GAZI, HUB, ISTE, ISTF, K, KNYA, and LE for permitting examination of their Salvia collections.
