Earthquake Focal Mechanism And Stress Tensor Analysisalong The Central Segment Of The North Anatolian FaultKarasozen, Ezgi 01 July 2010 (has links) (PDF)
The North Anatolian Fault (NAF) is one of the world&rsquo / s largest active continental strikeslip
faults, and forms the northern margin of the Anatolian plate. Although its geologic
and geomorphologic features are well defined, crustal deformation and associated
seismicity around central segment of the NAF is relatively less-known. In this study, we
analyzed locations and focal mechanisms of 172 events with magnitude &ge / 3, which are
recorded by 39 broadband seismic stations deployed by the North Anatolian Passive
Seismic Experiment (2005-2008). Distribution of the events shows that the local
seismicity in the area is widely distributed, suggesting a widespread continental
deformation, particularly in the southern block. For the entire data set, P- and S- arrival
times are picked and events are relocated using the HYPOCENTER program. Then,
relocated events which have a good azimuthal coverage with a maximum gap of 120° / and at least 13 P- wave readings are selected and 1-D inversion algorithm, VELEST, is
used to derive the 1-D seismic velocity model of the region. The final model with
updated locations is later put together to the FOCMEC program, to obtain focal
mechanisms solutions. In this step, an iterative scheme is applied by increasing the
number of data errors. To obtain more unique solutions, first motions of P and SH
v
phases are used along with SH/P amplitude ratios. Resultant 109 well-constrained focal
mechanisms later used to perform stress tensor inversion across the region.
Our focal mechanisms suggest a dominant strike-slip deformation along two major fault
sets in the region. In the east, E-W trending splays (Ezinepazari, Almus, and Laç / in
Kizilirmak) show right-lateral strike-slip motion similar to the NAF whereas in the west,
N-S trending faults (Dodurga, Eldivan) show left lateral strike-slip motion. Overall,
stress orientations are found as: maximum principal stress, &sigma / 1, is found to be
subhorizontal striking NW-SE, the intermediate principle stress, &sigma / 2, is vertically
orientated and the minimum principal stress, &sigma / 3, is found to be NE &ndash / SW striking,
consistent with the strike-slip regime of the region.

Evaluation Of The Effectiveness Of English Courses In Sivas Anatolian High SchoolsYel, Arzu 01 September 2009 (has links) (PDF)
This study evaluates the English language courses for 9, 10, 11, and 12th grades in Anatolian high schools in Sivas. The participants of the study were 200 students who were enrolled in the courses and 20 teachers who taught them. The quantitative data were obtained through different course evaluation questionnaires for students and teachers.
The eclectic evaluation model employed in this study was structured by adapting the evaluation models suggested by Bellon and Handler (1982) and Brown (1989).
The results of the study show that the courses were not much effective in reaching the goals and objectives of the program, the course content and materials were uninteresting for the students and materials were inadequate in providing opportunities for communicative and student-centered activities, the teaching and learning processes lacked variety, and the assessment procedures were not parallel with the objectives of the courses and approaches of the curriculum.
Some of the important recommendations of the study were that teachers need to be informed about the curriculum (i.e. goals and objectives, approaches), course content and materials need to be revised and supplementary materials for teaching of all language areas (four skills, grammar, and vocabulary) should be provided, variety needs to be added to the teaching activities, and the four skills (listening, speaking, reading, and writing) need to be assessed properly.

Evaluation Of The Adaptation Process Of A Reintroduced Anatolian Mouflon (ovis Gmelinii Anatolica) Population Through Studying Its Demography And Spatial EcologyOzut, Deniz 01 April 2010 (has links) (PDF)
In this thesis the demography, home range and habitat selection of a
reintroduced population of Anatolian mouflon (Ovis gmelinii anatolica),
which had a single remaining population, was studied to evaluate the
reintroduction success and determine the conservation management
interventions.
For this purpose among 104 individuals reintroduced in Sariyar
Wildlife Protection Area (Ankara, Turkey), 40 adults were radio-collared
and 28 juvenile were ear-tagged and monitored from 2005 to 2009. The
survival of the population according to the age groups (females, 0: 0.5423,
1: 0.60, 2: 0.5316, 3: 0.6637, 3+: 0.6728) and the fecundity of adult females (2:
0.2260, 3: 0.2034, 3+: 0.2034) are estimated. A population viability analysis
was performed and the persistence of the population within the next 20
years was estimated. Increasing the survival rate of adult female through
conservation or restocking the population with at least six adult females
every year decreased the risk of extinction in the near future considerably.
The year-round home ranges of the individuals ranged between 805
&ndash / 3435 ha. (Mean ± / SE: 1934 ± / 140 ha). The movements of the tracked
individuals followed seasonal patterns: centers of activities changed
according to seasons in 80% of the adult mouflon. Reintroduced mouflon
selected southern aspects (p=0.001), increasing slopes &ndash / especially medium
to high slope terrain &ndash / (slope > / 30° / , p=0.002), and distant locations to
villages and roads.
Results indicate that appropriate protective measures should be
implemented immediately to mitigate the causes of juvenile mortality.
Restocking the population for the next 10 years with adult females would
have a stabilizing effect on the declining population and will act as a
buffering mechanism during the adaptation period to the new area.

Transformation Of The Ottoman Built Environment In The Nineteenth Century In Anatolia: The Case Of TokatKardas, Aysegul 01 August 2011 (has links) (PDF)
In this study the Ottoman built environmet in the last period of the nineteenth century Anatolian city is examined. The study aims to explain the construction of new buildings as well as the transformation of earlier types during the process of contemporary modernization and centralization in the Empire. The main frame of the study is formed of the public and the private spaces that formed the urban built environment, and the transformation of these spaces. The city of Tokat has been chosen as the area of study, which still conserves built structures of the Ottoman as well as the earlier periods that are typical of an Anatolian city of the nineteenth century. Examining the transformation of public buildings and residential architecture in this city, this study emphasizes differences in degress of changes in public and private spaces, and the relation of such transformation with the central authority.

Technological Properties And Conservation Problems Of Some Medieval Bricks And TilesDincer, Senay Ayse 01 February 2012 (has links) (PDF)
The aim of this study is to examine the technology of the relatively deteriorated historic tile, brick and mortar samples of Sivas Gö / k Medrese and Tokat Gö / k Medrese. Their main deterioration factors were analyzed mainly as salt weathering. It was examined in detail, and the possible desalination methods were discussed.
For this purpose, the studies were carried out with a field survey and laboratory experiments on the two sites. Documentation of visual decay forms of Tokat Gö / k Medrese were done with AutoCAD.
The density and porosities of tile body and mortar samples were determined by using RILEM standards. The pore size distributions of tile and mortar samples were examined by Mercury Intrusion Porosimetry. Modulus of elasticity of tile body and mortar samples was determined and compared with the other Seljuk building materials. Mineralogical compositions of the tile body and glaze, adhesive tile mortars of Sivas Gö / kmedrese and Tokat Gö / kmedrese were analyzed with X-Ray Powder Diffraction (XRD). Their microstructure and chemical compositions were determined by using Scanning Electron Microscope coupled with Energy Dispersive X-Ray Spectroscopy (SEM-EDX).
The salts were determined for various methods such as spot tests and XRD analyses. The possible treatment methods of salt crystallization were discussed according to the properties of the examined samples.
One of the most essential causes of decay factor was salt crystallization for the two buildings which causes detachment and loss of tiles. The deteriorations were distributed over the upper and lower sides of the wall which were close to the dampness zones from the roof and above ground. The experiments proved different kinds of salts such as thenardite, sylvite, halite, natrite, nitratine and niter coming from the ground and the restoration materials such as cement based mortars. The relative humidity of the environments was compared with that of salt characteristics. It was proved that the tiles were adversely affected from salt crystallization. The best desalination method was discussed. Advection method by using poultices was based on the transformation of ions through the flowing moisture. The most prominent characteristic of the poultices must have smaller pore size distribution than original salty materials. The pore size distributions of the tiles and gypsum mortars were determined to compare and chosen the best poultice from the literature. It was concluded that kaolin-sand-based poultices having known properties was the best one as considering the pore size distribution of the tiles and mortars. The study on material properties and desalination process was expected to help different monuments having salt problem.

Institutional and Cultural Roots of Industrial Development in Modern TurkeyEskici, Burak January 2014 (has links)
In this dissertation I investigate the historical, institutional, and cultural roots of different regional development trajectories in modern Turkey. Historical comparison of two similar cities of 1920's, namely Kutahya and Kayseri, enabled me to solve the Anatolian Tigers Puzzle, which can be defined as how come very similar cities of rural Anatolia in 1920's experienced such different development patterns in the last 80 years. The most similar case design led to the model, which explains the different regional development patterns of Anatolian cities. In this model, I argue that behind the success story of Kayseri, there is a path dependent virtuous cycle, which was initiated by early state enterprises; accelerated via local institutional reforms during critical junctures; and sustained by socio-cultural context. This theoretical model explains not only the difference between Kutahya and Kayseri, but it is also in line with the success story of other developed Anatolian cities. / Sociology

GIS Least-Cost Route Modeling Of The Proposed Trans-Anatolian Pipeline In Western TurkeyKelly, Austin 10 May 2014 (has links)
The routing of the Trans-Anatolian Pipeline plays an important role in the future energy security of the European Union. The natural gas pipeline is planned to run from the natural gas fields in the Caspian Sea through Turkey. This project is a case study for a Geographic Information System (GIS) least-cost route analysis of a section of the proposed pipeline in Western Turkey. The route analysis comprised of weighting multiple types of criteria in a compiled risk assessment map that was analyzed by a least-cost algorithm to display the least hazardous route through the study area. Multiple varieties of criteria were considered such as, lithology, slope of terrain, environmental and social risk factors, e.g. proximity to natural reserves and urban centers, to provide the least hazardous route through the region. The derived least cost paths were more efficient than the proposed route in the relative cost associated with each route.

Monitoring Of Chemical And Isotopic Compositions Of Geothermal Waters Along The North Anatolian Fault ZoneSuer, Selin 01 September 2004 (has links) (PDF)
This study aims to determine the chemical (anion-cation) and isotopic compositions (& / #948 / 18O-& / #948 / D-3H) of the geothermal waters along the North Anatolian Fault Zone (NAFZ) and highlight any possible seismicity-induced temporal variations during the course of two years (2002-2003) monitoring programme. The geothermal sites are alligned along a 800 km transect of the NAFZ and are, from west to east, Yalova, Efteni, Bolu, Mudurnu, Seben, KurSunlu, Hamamö / zü / , Gö / zlek and ReSadiye.
The thermal waters of NAFZ are dominantly Na-HCO3, whereas the cold waters are dominantly Ca-HCO3 in character. The highest temperature (72.3& / #61616 / C) is recorded in Seben. The hot waters are slightly acidic to alkaline in character with pH values ranging between 5.92-7.97, while the cold waters are comparatively more alkaline with pH values between 6.50-8.83.
Both hot and the cold waters are meteoric in origin. The hot waters have lower & / #948 / 18O-& / #948 / D and tritium values suggesting higher recharge altitudes for aquifers and longer residence times for waters, respectively, in the geothermal system (compared to the cold waters).
Temporal variations are detected in both ionic and isotopic compositions of the cold and the hot waters, and these reflect seasonal variations for cold and seismicity-induced variations for hot waters. Although no major earthquakes (M> / 5) occurred along the NAFZ during the monitoring period, temporal variations recorded in Cl and 3H, and to a lesser extent in Ca and SO4 contents seem to correlate with seismicity along the NAFZ. In this respect, Yalova field deserves the particular attention since seismicity induced variations were better recorded in this field.

Origin And Significance Of A Quartz-tourmaline Breccia Zone Within The Central Anatolian Crystalline Complex, TurkeyDemirel, Serhat 01 September 2004 (has links) (PDF)
The aim of this study is to investigate the petrography, geochemistry and evolution of quartz-tourmaline-rich rocks occurring in a wide breccia zone within the Late Cretaceous Kerkenez Granitoid (Central Anatolian Crystalline Complex (CACC), Turkey). The approximately 40-m wide main breccia zone has a NE-SW trend and is characterized by intense cataclastic deformation. The breccia zone can be traced several kilometers towards the west and generally occurs as tourmaline-filled faults and 1mm-30cm-thick veins within the granitoid. On the basis of mineralogical and textural features, rocks within this zone are defined as tourmaline veins, tourmaline-breccias and quartz-tourmaline rocks. These rocks are generally composed of quartz, tourmaline and granitic fragments. Petrographical investigations and electron-microprobe analyses indicate that, there are three optically and chemically different tourmaline generations. From oldest to youngest, the tourmalines are classified as blue pleochroic feruvites, blue-green pleochroic schorls and green-light green pleochroic schorls. The chemistry of the tourmalines suggests that these tourmalines crystallized from boron rich fluids derived from an evolving magma. Consequently, the quartz tourmaline-breccia zone is considered to have formed by the injection of overpressured boron rich fluids into faults and fractures present within the Kerkenez Granitoid. Fluid-filled faults and fractures were sealed by quartz-tourmaline crystallization. This led to further fractionation in the magma, new fluid pressure accumulations, reactivation of faults and crystallization of different tourmaline generations. Tourmaline-breccia zones are scarce in the literature and the presence of such rocks within the CACC is first reported in this study.
