In this study, an Analytic Network Process (ANP) and Data Envelopment Analysis
(DEA) based approach was developed in order to measure the performance of
customer-based Research and Development projects being executed in TÜBTAKSAGE, Defense Research and Development Institute, under the Scientific and Technological Research Council of Turkey. In order to evaluate project performance, many criteria, containing various subcriteria were determined. In order to handle the interdependencies among the criteria and the sub-criteria, ANP was used. The ANP model generated in this study is a hybrid model consisting of both a hierarchy and a network. The pairwise comparison matrices that were built up for defining the importance and influences of the criteria/sub-criteria in the ANP model were formed as interval judgments from a group decision making process, based on data obtained from a questionnaire conducted among the experts in the Institute. From the interval pairwise comparison matrices, weight intervals for the sub-criteria were determined and these bounds were used as assurance region constraints in a super-efficiency DEA model, through which the project ranking was obtained. Taking into consideration that there may occur some missing values in some projects for some of the sub-criteria, the superefficiency DEA model was extended to handle missing data. The model was applied to a real case study on performance evaluation of the ongoing customer-based projects in the Institute. For comparison purposes, the case study was also solved by two other approaches.

The purpose of this study was to investigate perceptions of self-initiated professional development of English language teachers at English Language School of BaSkent University. Within this framework, teachers’
attitudes towards their professional development, their perceptions of major professional development activities, and the factors that hinder change and growth in teachers were investigated. The data collection instrument used was a questionnaire administered to 110 English language teachers at BaSkent University. The questionnaire consisted of both open-ended and close-ended items and the data collected were analyzed descriptively to understand the general trends and differences among teachers. The data analysis revealed that the teachers agreed with most of the concepts that reflect the importance of professional development. In addition, they were aware of the importance of major professional development activities for their growth. However, peer observation and action research, which are developmental activities, were not favoured as much as the other activities. In addition, it was found that the teachers did not make use of the activities as much as they gave importance to. Furthermore, teachers showed significant differences in importance given to and making use of the activities by the background variables. Female teachers, young teachers and the teachers who do not have much experience seemed to give more importance to and actualize some of the professional development activities more than the other teachers. Meanwhile, it was also noted that the listed factors that hinder growth were all found important by the teachers. The most important impediments to growth were indicated as excessive workload, lack of self-motivation and lack of institutional support for professional development.

ZDEN SEPTEMBER 2003 ,105 pages For many reasons, the use of computer based of assessment is increasing. Although there is an increasing usage of computer based exams, there are not enough researches about student perception towards online assessment in general and perception of students towards categorized fields of online assessment systems. To figure out the students&
#8217
perceptions of online assessment an exam web site has been developed and implemented. This web site is a database driven web site and containing multiple choice questions. This online assessment site used as assessment module of Masaü
stü
Yayincilik course given by Department of Computer Education, Kocaeli University. The perceptions of the students&
#8217
towards online assessment have been evaluated in terms of User interface, Impacts on learning process, System usage and general opinions on online assessment. The aim of the study is to investigate students&
#8217
perceptions of the use of CAA and to investigate the potential for using student feedback in the validation of assessment. The results indicated that students have positive attitudes against online assessment. Results of questionnaires showed that user interface of the assessment web site is proper and well designed but need to be further development. The system use of the web site is easy. The impacts of the learning progress of the web site are sufficient but assessment web site should be developed by enriching the system components meeting the student needs. Security should be ensured.

This thesis assesses how technology policy, R&D activities and innovativeness interact to yield higher economic performance in Turkish manufacturing industries. The first aim of this thesis is to analyze the role of R&
D support programs as one of the instruments of technology policy on the demand for researchers. We evaluated the impact of R&
D support receiving on the demand for researchers by estimating a two stage treatment effect model that solves the problem of selection bias and found that receiving R&
D support encourages firms to demand more researchers. The second aim of this thesis is to analyze the determinants of generating product and process innovations. We evaluated the determinants of generating product and process innovations by estimating a bivariate probit model and found that the determinants of generating product and process innovations were related but they varied with the technological level and opportunity of the industry. The last aim of this thesis is to analyze the effect of product and process innovations on employment. We hypothesized that these two types of innovations have different impacts on employment and test this hypothesis by estimating two different econometric models: the first one is a treatment effect model controlling for the endogeneity of innovations and the second one is a selection model that controls for survival status of the firm. We found that the impact of product innovations on the employment growth rate is negative and the impact of process innovations on the employment growth rate is positive regardless of technology level of industries.

It is a great advantage of gaining knowledge about the environment for navigation. The environment should be measured during the employment as exactly as possible, in order to be able to react correctly. Robots are being used for different tasks at contaminated environments, places in danger or completely safe places. For robotic use, scanning capabilities of the environment are limited at the present. Adhering to the limitations of the scanning systems, the environment is scanned at a particular level and charted with appropriate software. In some cases, this scanning capability is not enough to react correctly.
Taking these needs into consideration, this thesis successfully demonstrates the design and implementation of a scanning platform for mobile robotics. A scanning platform with a laser rangefinder scanner will be addressed in a compact design with maximum field of view for quickly mapping and high resolution.
With this design, the scanning system will be provided by rotating laser rangefinder at z-axis in one dimension. Laser rangefinder will also measure the distance as the second dimension of the system. Also it rotates the laser beam at another axis which is different from the measuring distance axis and rotary z-axis. In this way, the scanning system will have the three-dimensional scanning ability. This design allows the scanning platform, continuous scanning capability at three dimensional.

Using qualitative analysis, this thesis analyzes intergenerational support, conflict, and ambivalence between aging mothers and their middle aged adult daughters. In-depth interviews with 30 mother-daughter pairs explored respondents’
relationship history, changes in the relationship over the life course (childhood, adolescence, young adulthood, marriage of daughter, parenthood of daughter, widowhood of mother), social network composition, frequency of contact, expectations, type and frequency of intergenerational support, intimacy, compliance, conflict or disagreement, and comparison of self with the other party in terms of parenting styles and filial behaviors. Moreover, similarities and differences in the personalities of mother-daughter dyads were investigated from both mothers and daughters perspective. Participants reported that, there is an ample amount of intergenerational support between aging mothers and their adult daughters. Conflicts between mother-daughter pairs arise from interference, irritating personality traits and behaviors and differing views. Daughters experience more ambivalent feelings than mothers in their relationship. Both parties employ passive and secondary relationship maintenance tactics with the goal of preserving relationship harmony. Three distinct types of mother-daughter relationship emerged: close/peaceful, ambivalent and distant. Mother-daughter relationships have undergone transformations with life stages: daughters&

The objective of this thesis is to analyze the concept of &lsquoEuropean identity&rsquo
within the context of the European Union (EU) in terms of constructivist approach. This thesis is based on the idea that European integration project needs a shared identity
it is essential means for the success and continuity of an &lsquo
ever closer Union&rsquo
. In this context, the aim of the thesis is to find out the answers to the questions of whether the EU has a European identity
whether a post-national European identity is viable and desirable
if so, which model of identity is more viable and desirable. Through adopting the constructivist approach the main argument of this thesis is that a European identity is as a process and project. The thesis further argues European identity as a &lsquo
thin&rsquo
identity is still in the process of formation and its uncertain content and &lsquo
future-oriented&rsquo
character is open to new codifications. Accordingly, the thesis contains three main parts
the viable and desirable post-national European identity
the EU&rsquo
s identity building strategies
the impact of European integration and the effects of identity-building strategies on both national and European identities since the 1950s to present.

Full textAbstract:
The territory of Pontus once occupied by the Mithridatic Kingdom in the Hellenistic Period and fell under the Roman Empire in the first century B.C., layed between the Pontus Euxine (Black Sea) and the northern edge of the Anatolian plateau. In his Geography Strabo describes Pontus with a detailed account of the settlements. In his description of his hometown Amaseia (Amasya today), he mentions a plain with 1000 villages called Chiliocomum. Indeed, the archaeological survey data indicates that there were a large number of
settlements dating to the Hellenistic and the Roman period in this region. The aim of this thesis is to quantify the settlement - environment relationship and to investigate and compare settlement patterns in the Hellenistic and Roman
periods by using Geographical Information Systems (GIS).
Data sets are used in the study includes a settlement database, topography, road network, soil and current landuse which were spatially analysed in GIS. Raster analyses, proximity analyses and density analyses are conducted in order to understand and compare site distribution and landuse. The results of the GIS analyses revealed that settlements were located in particular areas of the
landscape. Some of these areas continued to be settled from the Hellenistic through the Roman period, while others were abandoned and alternative landscapes have replaced them. The results of the various analyses were utilized to discuss issues related to the shift in the political power and the socio-political structure in the region from the Hellenistic and to the Roman period.

AK, Ayfer MSc, Department of Educational Sciences Supervisor: Prof. Dr. Fersun Paykoç
September 2003, 115 pages The purpose of this study is to investigate whether, or not, students attending English Language Preparatory School at BaSkent University are ready to be involved in autonomous language learning. This study also argues that before any interventions aiming at fostering autonomy are implemented, it is necessary to explore learners&
#8217
readiness for autonomous learning in four different areas. These areas are as follows: (a) Learners&
#8217
motivation level in learning English, (b) Learners&
#8217
use of metacognitive strategies in learning English, (c) Learners&
#8217
responsibility perception of their own and their teachers&
#8217
in learning English and (d) Learners&
#8217
practice of English in the outside class activities. The questionnaire used in the study was administered to 186 students attending Preparatory School of BaSkent University. The data analysis was carried out through quantitative (frequencies, means, standard deviations, t-test and one-way ANOVA) analysis techniques. The results of the study indicated that majority of the students had high motivation. Another result revealed that the students tended to use some metacognitive strategies like self-monitoring and self-evaluation. The third result showed that the learners considered the teacher as more responsible for most of the tasks during their own learning process. Fourthly, majority of the students tended to be spending quite little time for out-of-class activities to improve their English. The fifth result displayed that females and elementary learners had higher motivation in learning English, but a significant difference was not in the motivation level concerning the learners&
#8217
major field. The sixth result pointed out that females used more metacognitive strategies in learning English
however, proficiency level and major field of the learners were not found to be significant factors in the use of metacognitive strategies. The seventh result revealed that responsibility perceptions did not show a significant difference regarding the respondents&
#8217
gender, proficiency level and major field. Finally, the present study indicated that intermediate level language learners tended to do more out-of-class activities in learning English. On the other hand, the frequency of respondents&
#8217
conducting out-of-class activities in learning English did not show a significant difference concerning the subjects&

Full textAbstract:
Breast cancer is the most frequent malignancy among women, especially in Western societies. Highly penetrant genes such as BRCA1 and BRCA2, together with the reproductive history can constitute only 30% of the cause, so there should be other common genes, which may play a role in breast carcinogenesis according to one's lifestyle. In our case, the effect of N-acetyl transferases (NAT1, NAT2) and glutathione-S transferases (GSTM1&
GSTT1) were investigated, since variations in these genes may alter their enzymatic activity and therefore their capacity to biotransform xenobiotic compounds. To evaluate the potential association between NAT1, NAT2, GSTM1 and GSTT1 genotypes and development of breast cancer, a hospital based case-control study was conducted in a Turkish study population consisting of 37 histologically confirmed incident breast cancer cases and 34 control subjects with no present or previous history of cancer. The only recognizable difference between case and control groups is the percentage of GSTM1 deletion, 67.6% and 44.1% respectively (p=0.047). The frequency of rapid NAT2 acetylator genotype is 44.4% in cases and 23.5% in controls. Especially, women with NAT2 rapid acetylator and GSTM1 null genotypes were at the elevated risk (OR, 3.8
CI, 0.9-15.4). NAT1 rapid acetylator genotype showed no association with breast cancer. These results suggest that GSTM1 null genotype is a susceptibility factor for breast cancer, particularly in the presence of NAT2 rapid acetylator genotype.

First, 17 high schools (4 private, 3 Anatolian, 6 regular, and 4 vocational) were determined in Ankara province, and then 17 English teachers, one from each school, were selected based on the predetermined criteria. Totally, 17 teachers and 17 administrators were included in the study. Observations, document analysis, and interviews were used to collect the data. The data were analyzed through content analysis. The data were categorized under emerged themes, general technology knowledge, planning, using, evaluation and assessment, personal purposes, attitudes, support, and wishes. The findings of the study indicated that private high school teachers perceived themselves more knowledgeable in technology knowledge than regular, Anatolian, and vocational high school teachers. In addition, the interview results showed that private high school teachers integrate technology into planning, instruction, evaluation and assessment, and professional development more than the other English teachers. When school resources and support mechanisms were compared, private high schools were in a better condition than public high schools. Finally, most of the administrators included in the study wanted teachers use available school resources in their lessons.

Extravehicular Activity (EVA) spacesuits are a key enabling technology which allow astronauts to survive and work in the harsh environment of space. Of the entire spacesuit, the gloves may perhaps be considered the most difficult engineering design issue. A significant number of astronauts sustain hand and shoulder injuries during extravehicular activity (EVA) training and operations. In extreme cases these injuries lead to fingernail delamination (onycholysis) or rotator cuff tears and require medical or surgical intervention. In an effort to better understand the causal mechanisms of injury, a study consisting of modeling, statistical and experimental analyses was performed in section I of this thesis. A cursory musculoskeletal modeling tool was developed for use in comparing various spacesuit hard upper torso designs. The modeling effort focuses on optimizing comfort and range of motion of the shoulder joint within the suit. The statistical analysis investigated correlations between the anthropometrics of the hand and susceptibility to injury. A database of 192 male crewmembers' injury records and anthropometrics was sourced from NASA's Johnson Space Center. Hand circumference and width of the metacarpophalangeal (MCP) joint were found to be significantly associated with injuries by the Kruskal-Wallis test. Experimental testing was conducted to characterize skin blood flow and contact pressure inside the glove. This was done as part of NASA's effort to evaluate a hypothesis that fingernail delamination is caused by decreasing blood flow in the finger tips due to compression of the skin inside the extravehicular mobility unit (EMU) glove. The initial investigation consisted of a series of skin blood flow and contact pressure tests of the bare finger, and showed that blood flow decreased to approximately 60% of baseline value with increasing force, however, this occurred more rapidly for finger pads (4N) than for finger tips (ION). A gripping test of a pressure bulb using the bare hand was also performed at a moderate pressure of 13.33kPa (100mmHg) and at a high pressure of 26.66kPa (200mmHg), and showed that blood flow decreased 50% and 45%, respectively. Excessive hyperperfusion was observed for all tests following contact force or pressure, which may also contribute to the onset of delamination. Preliminary data from gripping tests inside the EMU glove in a hypobaric chamber at NASA's Johnson Space Center show that skin blood flow decreased by 45% and 40% when gripping at 3 moderate and high pressures, respectively. These tests show that finger skin blood flow is significantly altered by contact force/pressure, and that occlusion is more sensitive when it is applied to the finger pad than the finger tip. Our results indicate that the pressure on the finger pads required to articulate stiff gloves is more likely to impact blood flow than the pressure on the fingertips associated with tight or ill-fitting gloves. Improving the flexibility of the gloves will therefore not only benefit operational performance, but may also be an effective approach in reducing the incidence of finger injury. Space Policy Abstract EVA injury is only one of many dangers astronauts face in the extreme environment of space. Orbital debris presents a significant threat to astronaut safety and is a growing cause of concern. Since the dawn of satellites in the early 1950's, space debris from intentionally exploded spacecraft, dead satellites, and on-orbit collisions has significantly increased and currently outnumbers operational space hardware. Adding to this phenomenon, the advent of commercial spaceflight and the recent space activities in China and India to establish themselves as spacefairing nations are bound to accelerate the rate of space debris accumulating in low Earth orbit, thus, exacerbating the problem. The policies regulating orbital debris were drafted in the 1960s and 1970s and fail to effectively address the dynamic nature of the debris problem. These policies are not legally enforced under international law and implementation is entirely voluntary. Space debris is a relevant issue in international space cooperation. Unless regulated, some projections indicate space debris will reach a point of critical density, after which the debris will grow exponentially, as more fragments are generated by collisions than are removed by atmospheric drag. Space debris proliferation negatively impacts human spaceflight safety, presents a hazard to orbiting space assets, and may lead to portions of near-Earth orbit becoming inaccessible, thus limiting mission operations. The aim of this research effort was to review current international space policy, legislation and mitigation strategies in light of two recent orbital collision episodes. The first is the February 2009 collision between a defunct Russian Cosmos spacecraft and a commercial Iridium satellite. The second is China's display of technological prowess during the January 2007 intentional demolition of its inactive Fengyun-IC weather satellite using a SC-19 antisatellite (ASAT) missile. In each case the stakeholders, politics, policies, and consequences of the collision are analyzed. The results of this analysis as well as recommendations for alternative mitigation and regulatory strategies are presented.

Full textAbstract:
This study was carried out to analyze tomato samples and tomato seeds, purchased
from different food markets of Turkey randomly, for the presence of genetic
modification by using PCR method as it allows more specific detection. The DNAs
of collected samples were isolated according to CTAB DNA extraction protocol and
also with extraction kits. Screening tests of tomatoes were done by targeting 35S
promoter, NOS terminator and NptII kanamycin resistance gene with eight different
primer sets. Real time PCR is used to confirm 35S and NOS positives results
obtained from conventional PCR.
In this study, it was observed that 14 out of 35 seed samples, and 14 out of 40 fresh
tomato samples which were screened had at least one transgenic element of 35S promoter, NOS terminator and NPTII kanamycin resistance gene indicating the
possible presence of genetic modifications.
After screening, gene specific studies were carried out for PG, sam-k indicating F
type ripening delayed tomato and the 35 1 N lines respectively and cry1Ac genes
inserted in 5345-1 insect resistant tomato line. PG and sam-k specific primers were
not amplified in any of the samples investigated whereas 18 out of 75 samples were
cry1Ac positive and 1 out of 75 samples was sam-k positive. Positives were
confirmed by sequence analysis.
Additionally, construct specific primers specific to 5345-1 and 35 1 N lines were
designed. PCR amplicons indicate the existence of the construct sequence. In order
to verify the results, PCR products were sent to sequence analysis

Full textAbstract:
This thesis analyzes the analogy between woman and nature and ecofeminist theory that emphasizes the parallelism between man's exploitation of woman and nature. It aims to make an ecofeminist analysis of three novels: Surfacing by Margaret Atwood, The Cleft by Doris Lessing and The Stone Gods by Jeanette Winterson. First, this thesis introduces the history and main principles of ecofeminist theory. These novels by different women writers investigate the embodiment of these main principles in three novels despite the fact that the same aspects of the theory can sometimes be interpreted differently in these novels. In analyzing these three novels as applications and/or the criticisms of ecofeminist theory, it was found that two theories, social ecology and Cyborg Theory, are also necessary. The later novels use ideas from these related theories alongside ecofeminist ideas. In order to undertake this analysis in each novel, this thesis also studies the assignment of determined social roles to man and woman and the duality resulting from this inequality. Next, it investigates the colonization of both nature and woman'
s body by man&
#8217
s intervention, that leads to the alienation of woman from herself and society. Furthermore, this thesis shows the exploitation process of females and nature by males who consider both as objects.

Full textAbstract:
In the most of the drilling operations it is obvious that a considerable amount of money is spent for drilling related problemsincluding stuck pipe, lost circulation, and excessive mud cost. In order to decrease the percentage of non-productive time (NPT) caused by these kind of problems, the aim is to control annular frictional pressure losses especially in the fields where pore pressure and fracture pressure gradient is too close which is called narrow drilling window. If we can solve these problems, the budget spent for drilling the wells will fall, therefore enabling the industry to be able to drill wells that were previously uneconomical. Managed Pressure Drilling (MPD) is a new technology that allows us to overcome these kinds of drilling problems by controlling the annular frictional pressure losses. As the industry remains relatively unaware of the full spectrum of benefits, this thesis involves the techniques used in Managed Pressure Drilling with an emphasis upon revealing several of its lesser known and therefore less appreciated applications.

Full textAbstract:
The aim of this study is to extract information about mineral distribution and
percentages of Oymaagaçgranitoid (Beypazari-Ankara) by using remote sensing techniques. Two methods are applied during the studies which are spectral analysis and Crosta techniques. Spectral measurements are done for fresh and weathered samples collected at 32 locations. Mineral percentages are calculated using spectral mixture analysis for each sample by considering main, accessory and secondary mineral content of granodiorite. A total of 10 endmembers for fresh samples and 15 for weathered samples are used. USGS spectral library data is utilized through the analyses. For Crosta technique (image analysis) the multispectral ASTER satellite image is used. Five alteration minerals are discriminated and their maps are generated during this analysis. Interpretation and comparison of the results of both methods and testing these results with the existing petrographical and geochemical data indicate that: 1) according to the results of both spectral analyses and Crosta technique a zonation is not observed in the granitoid, 2) comparison of the results for alteration minerals of these two analyses are partly compatible but not exactly similar, 3) Results of spectral analysis do not fit geochemical nor modal analyses because of inconsistency of the data sets.

Full textAbstract:
The focus of this study is to be able to control the air-to-surface missile
throughout the entire flight, with emphasis on the propulsion phase to increase the
impact range of the missile.
A major difficulty in controlling the missile during the propulsion phase is the
important change in mass of the missile. This results in sliding the center of gravity
(cg) point and changing inertias. Moreover, aerodynamic coefficients and stability
derivatives are not assumed to be constant at predetermined rangesconversely, they depend on Mach number, angle of attack, and side slip angle. Consequently, as the change of missile mass, cg point, inertia terms, and stability and aerodynamic coefficients come together apart from flight operation stages, a great number of points need to be taken into account when designing the controller. This makes controlling the missile all the more complicated. In this thesis, first the equations of motion are derived, in which, mass of the missile is not assumed constant. Thus, not only the variation of mass but also the variation of inertias is incorporated in the equations of motion. From the derived v equations of motion, a nonlinear inverse dynamics controller that can achieve desired guidance for a conceptually developed air-to-surface missile has been designed, tested and verified for a modeled missile with six degrees of freedom. For brevity of the study, conceptual design and aerodynamic calculations are not given in detail. Nevertheless, improvements for conceptual design are suggested. As a result, it is shown that the controller works efficiently: the missile is able to hit the target with less than 12 m circular error of probability (CEP). Finally, studies and improvements are proposed.

Mobile devices such as PDAs and cellular phones became indispensible part of business and entertainment world. There are a number of applications run on these devices and they tend to increase day by day causing devices tend to consume more battery power. H.264/AVC is an emerging video compression standard that is likely to be used widely in multimedia environments. As a mobile application, video compression algorithm of H.264 standard has a complex structure that increase the power demand of realizing hardware. In order to reduce this power demand, power consuming parts of the algorithm like deblocking filter and transform&quantization need to be specifically changed for low power application. A low power deblocking filter and inverse transform/quantization algorithm for H.264/AVC decoder is to be proposed and implemented on FPGA.

The seed orchard of Prunus avium L., Čejkovka, LS LČR Lužná, was established in 2002. Low seed production is characteristic for the orchard. First seed collection took place in 2015, summing up to 35 kilograms. Based on genetic analysis, S locus alleles and microsatellite data were detected. Furthermore, phenology of blooming and fertility of individual ramets was observed. It was detected that from the registered 59 clones, 46 clones were of different genotypes and 29 clones are diferrent in S locus. Approximately 37% ramets in the orchard are genetically identical. In 2015, a total of 45% ramets produced seeds. Based on evidence, the effective number of clones in the orchard is 31, 12 based on SSRs and 10 based on S locus. The number of seed producing clones in 2015 was 20 based on evidence, 8 based on SSRs and only 5 based on S locuses. In order to achieve higher seed production it would be appropriate to partially supplement genetically identical clones with those of different genotypes. An additional option would be utilizing the existing orchard to collect grafts to establish a new, appropriately designed, orchard.

Forty-two ninth grade students from two classes of a chemistry course taught by the same teacher in METU Development Foundation Private School 2000-2001 spring semester were enrolled in the study. The classes were randomly assigned as control and experimental groups. Students in the control group were instructed by traditionally designed chemistry instruction whereas students in the experimental group were taught by the instruction based on constructivist approach. Chemical Bonding Concept Test was administered to both groups as a pre-test and post-test in order to assess their understanding of concepts related to chemical bonding. Students were also given Attitude Scale Toward Chemistry as a School Subject at the beginning and end of the study to determine their attitudes and Science Process Skill Test at the beginning of the study to measure their science process skills. The hypotheses were tested by using analysis of covariance (ANCOVA) and two-way analysis of variance (ANOVA). The results indicated that instruction based on constructivist approach caused a significantly better acquisition of scientific conceptions related to chemical bonding and produced significantly higher positive attitudes toward chemistry as a school subject than the traditionally designed chemistry instruction. In addition, science process skill was a strong predictor in understanding the concepts related to chemical bonding. On the other hand, no significant effect of gender difference on understanding the concepts about chemical bonding and students&

Full textAbstract:
Soils in many agricultural areas have high pH, resulting in low availability of zinc and iron. Plants grown on such soils suffer from either Zn or Fe deficiency or both.
The efficient plant genotypes grown normally in calcerous soils were found to evolve some strategies to acquire the iron which is in insoluble form. Iron efficient graminaceous monocots release iron chelating substances, mugineic acid family phytosiderophores (MAs), in response to iron deficiency stress. Several researchers have suggested that phytosiderophores also can play role in grass Zn nutrition and thus it may be possible that it is the uptake mechanism for Zn efficiency. Several possible genes that take role in phytosiderophore synthesis or found to be induced under iron deficient conditions were identified in several organisms but not on wheat.
In this study, the efficient barley cultivar Tokak-157, efficient wheat cultivar Kiraç-66 and relatively less efficient wheat cultivar BDMM-19 were grown in normal growth conditions for 1 week and transfered to zinc deficient, iron deficient and both zinc and iron deficient nutrient solutions. After growing 1 week on these conditions, plants grown on both zinc and iron deficient nutrient solutions were retransfered to zinc and iron sufficient conditions. Degenerate primers were designed for the conserved regions of previously identified genes that take role in phytosiderophore synthesis or induced under iron deficient conditions and RT-PCRs were performed. The complete open reading frame of IDI-1(Iron deficiency induced-1) gene and the putative gene fragment for SAM-s (S-adenosylmethionine synthetase) were identified.

Full textAbstract:
This thesis aims to explore the challenges of Medical Devices sector in their innovative activities with the use of qualitative and quantitative methods. The specific subject of analysis is the Turkish Medical Device industry. Throughout the thesis the convergence of Medical Devices with pharmacy and its role in healthcare is mentioned in addition to the institutional regulations of the sector due to their effect on the firms innovative activities. The main focus of this thesis is the innovation in medical devices as vital components of healthcare supply with an important share in health expenditures. Even though Medical Devices are considered to be heterogeneous and classified in many other sectors such as chemicals, textiles and electronics, they have common features sufficient to be considered as a special product group and being an important part of the healthcare system, they are subject to common regulations. Sectoral Systems of Innovation approach is used to investigate Medical Devices Sector in Turkey. Medical devices sector also suffer from regulations that put cost on innovative activities, reimbursement policies that aim at cost containment, lower degrees of consumer support (in terms of user-producer relationship), high marketing costs due to the specific market they act in, in addition to the general obstacles such as scarce finance and human resources. Nonetheless, the ambiguity in entrance and allowance to reimbursement lists is also found to be a blocking factor on innovation.The studies on this aspect of the medical devices sector are limited and this thesis aims to fulfil the gap in this respect.

Ucar, Onder. "The Historiography Of Young Turk Revolution &." Master's thesis, METU, 2011. http://etd.lib.metu.edu.tr/upload/12612809/index.pdf.
Full textAbstract:
This thesis points to the existence of a bourgeois revolution in the history of the Ottoman Empire. Against all approaches of the historiography on the subject which employ outmoded criteria and point to a duality between the moments in 1908 and 1923it employs contemporary arguments on bourgeois revolutions and argues that the Ottoman Empire witnessed a single revolutionary sequence which occurred between July 1908 and November 1922. The thesis also suggests the idea that this single revolutionary sequence of the Ottoman Empire was a bourgeois revolution.

Full textAbstract:
I den här undersökningen ville jag få reda på hur det går till att undervisa, handleda och att studera ämnet bild via internet och datorn, i vad som kallas distansutbildning. Mina undersökningsområden var en distansgrundskola i Sverige samt en skola utomlands där de bedriver distansutbildning genom att få utbildningsmaterial från distansgrundskolan i Sverige. Jag intervjuade en distanslärare i bild på distansgrundskolan i Sverige, samt mailintervjuade en handledare och två distanselever som befinner sig utomlands. Eleverna studerar på en skola utomlands där de får distansutbildning från Sverige. De studerar ämnet bild genom att få bild-uppgifter via internet av bildläraren i Sverige. En handledare finns till hjälp för distanseleverna på skolan utomlands för att de ska klara av distansstudierna. Den här undersökningen gjordes utifrån mitt eget intresse för distansstudier. Jag hade dock inga förkunskaper om hur bildämnet fungerar på distansgrundskola. De distanskurser jag själv studerat har varit på universitets och högskolenivå, och kan därför inte riktigt jämföras med grundskolans distansundervisning. Därför blev undersökningen spännande för mig och jag fick reda på sådant som jag inte visste angående hur distansstudier kan vara på grundskolan. Distansutbildning tycker jag inte behöver vara kopplat till att vara ”distanserad” utan snarare så kan man genom distansutbildning hålla kontakt med varandra via internet. Några frågor som uppkom i denna undersökning var:Vad är det roligaste med att undervisa på distans? Finns det några svårigheter med distansundervisning i grundskolan och vilka i såfall?Vad finns det för orsaker till att elever studerar på distans? Blir distanselevernas bilder mer olika varandra tror du?

Full textAbstract:
Polisen använder i stor utsträckning fordon som en del av sitt arbete. Fordonet är inte bara ett transportmedel, det är ett arbetsverktyg och inte minst en arbetsplats. Under övningar med utryckningsfordon upplevde vi det svårt att sitta bekvämt och ergonomiskt riktigt i de bilstolar som fordonen är utrustade med. Bilbältet stod även för ett problemområde i sig. Vi stötte på en potentiell säkerhetsrisk under våra empiriska försök vid Polisutbildningen i Umeå. Eftersom vi i hög grad kommer att vistas i fordon under vår yrkesutövning kändes det angeläget att belysa arbetsmiljön i just polisiärt utryckningsfordon. Detta med inriktning mot bilstol samt bälte och vilka konsekvenser det medför när fordonet inte är anpassat för ändamålet. Vi hoppas kunna identifiera problem och komma med förslag till förbättringar.
