Mapping class groups of surfaces play a central role in the theory of low dimensional topology. Any information about algebraic structure of these groups might be useful in the solution of some topological problem of low dimensional manifolds. That is one reason why understanding algebraic sturucture of mapping class groups is so important. Consider a nonorientable connected genus g surface with k marked points. The main task of this project was to obtain information on the algebraic structure of the mapping class gorups of these surfaces. Through the project we have obtained results about automorphism groups of curve complexes of nonorientable surfaces and we gave some immediate applications of these results. In particular, we have shown that any isomorphism between two finite index subgroups of the mapping class group is given by the restriction of an inner automorphism of the mapping class group. Moreover, we have shown that the outer automorphism group of a nonorientable punctured surface of genus at least five is tirivial. Finally, we have observed that the Torelli subgroup of a nonorientable surface contains the generators analogous to those of orientable surfaces.
Lineer Olmayan Üçlü Schrödinger Denklemi İçin Yapı Koruyan Sayısal Yöntemler
(2016) Ertuğ, Sevim; Aydın, Ayhan
A nonlinear implicit energy-conserving scheme and a linearly implicit mass-conserving scheme are constructed for the numerical solution of a three-coupled nonlinear Schrödinger equation. Both methods are second order. The numerical experiments verify the theoretical results that while the nonlinear implicit scheme preserves the energy, the linearly implicit method preserves the mass of the system. In addition, the schemes are quite accurate in the preservation of the other conserved quantities of the system. Elastic collision, creation of new vector soliton, and fusion of soliton are observed in the solitary wave evolution. The numerical methods are proven to be highly efficient and stable in the simulation of the periodic and solitary waves of the equation in long terms. Dispersive analysis of the equation and the numerical methoda is investigated.

Multiple Sclerosis (MS) is a degenerative nervous system disorder which results from demyelinazation. The disorder whose etiology is not fully understood and which cannot be cured influences the person’s psychological health, daily lives and relationships, as well as their physical health. The aim of the current study is to investigate the adjustment to illness process, identify the needs, problems and psychological symptom level and its predictors of both the patients and their caregivers. To fulfill this aim, bu using both qualitative and quantitative method, information gathered from 40 MS patients and their caregivers is evaluated. Semi stuructured interviews were conducted and scales were administered measuring MS symptoms, health locus of control, ways of coping, caregiver well-being psychological symptoms. Results of the qualitative analysis revealed physical disability and illness symptoms, difficulties with social life, anxiety about the future and illness representations themes for the problems of patients. The needs of the patients were faith, social support and material needs. For the caregivers, the problems were illness symptoms, anxiety about the future and limitations of social life; whereas the needs were material, information and support and help. The results of the quantitative analyses revealed that as the level of physical symptoms increases, and the use of problem focused coping decreases, the level of psychological symptoms inceases. For the caregivers, as the level of fulfilling basic needs increases, as the use of problem focused coping decreases and as the use of emotion focused coping increases; the level of psychological symptoms inceases, too. Combining the qualitative and quantitative results, the themes specific to the patients whose level of psychological symptoms are high, were loneliness and rejection, for the caregivers negative point of view and rigidity. The results of the current study has important implications in terms of including both caregivers and the patients to the research focusing on chronic illnesses, as well as guidance for the psychosocial interventions for chronically ill people and their caregivers
Low Temperature Behavior Of Hma And Sma Mixtures/tas Mastik Asfalt ve Bitümlü Sıcak Karısımların Düsük Sıcaklık Altındaki Davranısı
Low temperature cracks in asphalt concrete pavements are commonly seen in the East, interior, and west interior Anatolian regions of turkey where air temperature falls below -20 °C, or so low that the developed thermal stress exceeds the thermal strength of asphalt concrete and causes cracks. Low temperature cracking reduces the roadway's driving comfort by the increased surface roughness due to fracture, leading to the seepage of melting snow and rainfall water into the subgradethrough the surface cracks and causing loss of bearing capacity). Combined with the disruption caused by traffic loading, low temperature cracking weakens the structural integrity of the pavement and eventually increases roadway maintenance and rehabilitation costs. Low temperature cracking is one of the main reasons for pavement deterioration, ranked as the second factor in roadway maintenance and repair costs in the Northern regions (Figure 1). Stone Matrix Asphalt (SMA) has been widely used in turkey highways, it provides stone-on-stone contact and high asphalt content that can increase a pavement’s durability and resistance to rutting and reduce noise. However, drainage of binder and higher primary costs could be mentioned of its disadvantages. Since there is no consensus about the performance of SMA at low temperature, conducting a comprehensive study with different tests on the performance of Stone Matrix Asphalt at low temperatures would be beneficial. This project aims at characterizing the low temperature behavior of the Stone Matrix Asphalt (SMA) and HMA in terms of gradation type,aggregate and asphalt type. Upon completing this proposed project, low temperature performance of SMA would be investigated, and a significant contribution will be provided to achieve long lasting pavements without frequent maintenance and rehabilitation. It is believed that the research outcomes will contribute to the national and international knowledge considering the fact that there is only a limited study available in the literature on low temperature performance of SMA.
Elektrokatalitik Amonyak Üretimi için Ce Katkılı Lafeo3 Perovskit Malzemesinin Geliştirilmesi
Ammonia is the second most produced chemical worldwide, which has a wide range of uses in the production of cleaning products, nitrogen-containing chemicals and explosives in sectors such as energy, cooling, textile, fertilizer, medicine. Also, a good source of hydrogen, ammonia has the potential to play an important role in the future hydrogen economy. Ammonia production has thermodynamic limitations and is commercially produced by the Haber-Bosh process at high pressure and high temperature. Electrocatalytic ammonia production processes eliminate thermodynamic limitations and provide ammonia production at atmospheric pressure. Studies on ammonia production by using solid oxide conductors are still ongoing, and research using oxide conducting electrolytes are limited. Ammonia production in oxide conducting electrolytes provides thermodynamically an advantage over the Haber-Bosh process, but the cathode catalyst is also very important for the development of the membrane electrode system. The catalyst to be used in oxide conducting electrolyte is expected to be active for ammonia production, to have high ionic and electrical conductivity, and to have high strength and stability under operating conditions. In addition, the compatibility of the electrolyte material and the thermal expansion coefficient of the catalyst to be used in the system is another important parameter. Perovskite materials have the potential to have these properties, and the properties of perovskites can be improved by adding various metals to their structure. Electrocatalytic studies in the literatüre widely use yttria stabilized zirconia (YSZ) stabilized, which can easily be obtained commercially, as the solid oxide electrolyte material. Within the scope of the proposed project, LaFeO3 that has thermal expansion coefficient close to YSZ will be synthesized and the effectof doping with Ce in different ratios on the katalyst properties will be examined by characterization methods. There are currently no studies in literatüre that use of La1-xCexFeO3 cathode catalyst for the production of ammonia in oxide conducting electrolyte system. As a result of the study, the development of an active and selective cathode catalyst with high ionic and electrical conductivity, compatible with YSZ electrolyte, for the production of ammonia using solid oxide electrolyte will contribute to the literature. Outcomes of this project are planned to be published in national/ international journals and/or presented in national/international conferences.
Synthesis and Polymerization of Monomers Possessing Chemiluminescence Properties and Their Application Areas
A novel class of chemiluminescence (KL) compounds was designed, synthesized and characterized; 2,3-dihydro-thieno[3,4-d]pyridazine-1,4-dione (T-Lum), 2,3-dihydro-furo[3,4-d]pyridazine-1,4-dione (FLum) and 2,3-dihydro-pyrrolo[3,4-d]pyridazine-1,4-dione (P-Lum). The KL reaction of the compounds in alkali medium was examined by using hydrogen peroxide and potasium permanganate oxidants and a possible KL mechanism was investigated. Synthesized compounds are especially sensitive to Fe+3 ion and this property makes them amenable to use as iron sensors. Also, the sensitivity of these materials towards iron makes them a promising candidate in forensic area to detect trace amount of blood at crime scene. Compounds are also sensitive both iron and blood samples even at lower concentration. By using the sensitivity of compounds towards hydrogen peroxide, the detection of many analytes will be possible. Beside the KL property, the electrochemiluminescence (EKL) property of the materials makes them very precious. Since the oxidation of pyridazine ring occurs before the aromatic rings, electropolymerization of the functionalized pyrrole, furan and thiophene compounds with pyridazine rings were not possible. To overcome this problem, new compounds, which have lower oxidation potential than that of pyridazine ring, were designed, synthesized and characterized; 5,7-di-tthiophen-2-yl-2,3-dihydro-thieno[3,4- d]pyridazine-1,4-dione (TTT-Lum) and 5,7-di-ethylenedioxythiophene-2-yl-2,3-dihydro-thieno[3,4- d]pyridazine-1,4-dione (ETE-Lum). The materials synthesized in the form of donor-acceptor-donor exhibit both KL and EKL properties, which makes them promising candidates in the analytical chemistry and forensic science. Compounds were polymerized successfully without oxidizing pyridazine ring via electrochemical polymerization (only neat BF3-Et2O solution or 0.1 M LiClO4 or 0.1 M tetrabutylammonium perchlorate dissolved in acetonitrile containing 5% of BF3-Et2O by volume ) and the electrochemical and optical properties were investigated. Electroactive and electrochromic polymeric materials, exhibiting reversible redox behaviours, have lower band gaps between 1.6 and 1.7 eV. Also, the polymer films are very stable; the electroactivity and the EKL properties were remain unchangeable after many cycles. Furthermore, the soluble polymer films in alkali medium with their KL properties will attract many attention in the academic areas.
Sürekli Nanomalzeme Üretimi için Alev Aerosol Reaktör Tasarımı, Kontrolü ve Simülasyonu
Due to its advantages compared to the wet chemistry methods, Flame Aerosol Technology is used to produce 90% (by volume) of the commercial nanomaterials continuously in a faster, cheaper way, and in a single step [1-2]. Evolved by combining combustion and aerosol technologies, a large span of materials from salts to metal oxides can be produced by this method [3]. In this technology, the most important issue is to produce the desired phase in the desired purity and morphology, and to understand the effect of the process parameters that control these properties. This is mostly because it takes place at very high temperature, where momentum, heat and mass transfer phenomena take place simultaneouly, as well as the combustion of fuel and the reaction of the metal salts in the flame. In order to apply this fast and high temperature process to the industrial scale, there is a need for well controlled laboratory experiments that allows to produce models which can be used to simulate the experimental results. In this proposal, a well controlled flame reactor will be designed, and the effect of the operation conditions on the final nano particle size, morphology and crystal phase will be investigated. The aim is to control the process conditions in a way that allows the tailor-made nanoparticles especially for heterogeneous catalytic applications. Computational Fluid Dynamics package FLUENT will be used along with a user defined “population balance” model in order to estimate the nanoparticle size, and compared with the experimental results. A new reactor will be designed and constructed with the help of the simulation, and metal oxides (e.g. TiO2, Pd/Co3O4 ) will be produced under different operating conditions. The nanoparticles produced will be characterized for their size and morphology, and the validity of the simulation model will be checked.
Plastikleştirilmiş Poli(laktik Asit)’in Alev Dayanımının Fosfor Bazlı Katkı Maddeleri ile Geliştirilmesi
The aim of this study is to improve the flame resistance and toughness of PLA by adding small amounts of different flame retardant additives and plasticizers at the same time. Poly(ethylene glycol) (PEG) was used as a plasticizer. Phosphate-based chemicals as flame retardant additives; ammonium polyphosphate (APP), boron phosphate (BP) and tri-phenyl phosphate (TPP) were used. Within the scope of the project, the synergistic effects of the double and triple compositions of these flame retardant additives were also examined. The mixtures are produced by melt blending and injection molding methods. The effect of the type and composition of flame retardant additives on the properties of PLA composites was determined by various mechanical, thermal and flammability tests.
Preparation Of Magnetic Nanoparticles Which Enable The Use Of 18f-fdg As Multi-modal İmaging Agents İn Pet-mrı Applications/18f-fdg Nin Pet-mr Görüntüleme Uygulamalarında Multi-modal Görüntüleme Ajanı Olarak Kullanılmasına Yönelik Manyetik Nanoparçacıkların Hazırlanması
It is becoming increasingly evident that PET-MRI multi-modal imaging systems have great potential in practical medicine and for basic scientific research. Consequently there is a wide interest in developing proper imaging agents for these applications. Superparamagnetic iron oxide (SPIO) nanoparticles are already, extensively, being used as MRI contrast agents. The labeling of these nanoparticles with radioactive isotopes provides a new generation for MRI agents. Combination of the required properties, in the body of the same sample for both measurement techniques, ensures that both images are coming from the same spot and simultaneously. This approach provides more accurate and reliable data for diagnosis and treatment of the illness. One of the candidates of the applicable radioactive isotopes is 18F, an easily available one and is being produced in our country. However its chemical binding to delivery agents requires several steps of exhaustive chemical treatments. A laboratory/firm which tends to fabricate iron oxide nanoparticles labeled with 18F should reconstruct a new manufacturing plant, which needs a laborious and a quite expensive operation. Instead, a new process, which can convert already available PET contrast agents into PET-MRI agents without requiring any special expertise, would be more practical and economical.
Alan Özelinde Sosyalleştirme Yaklaşımı Çerçevesinde Etkili Ebeveynlik: Annenin Duygusal Erişilebilirliği ile Gelişimsel Çocuk Çıktıları Arasındaki İlişki
This study aims to examine effective parenting within the framework of the domains-of_x0002_socialization approach. Three separate studies were carried out. In the first study, Domain_x0002_Specific Parenting Interview (DSPI) was developed to measure parenting quality in different socialization domains and its psychometric properties were examined. The deductive content analysis of the DSPI was carried out in the second study. In the third study, the replicability of the first study was tested, the interactions between different socialization domains were examined qualitatively, and the relations of mothers' knowledge on effective parenting and the quality of their parenting behaviors with developmental child outcomes were examined. The participants of the first study consisted of 82 mothers with children between 35-76 months. The participants of the second study consisted of 50 mothers, which were randomly selected from the data set of the first study. The participants of the third study consisted of 141 mothers and fathers, who have children aged between 47-72 months. The findings of the first study provided evidence that DSPI is a valid and reliable measurement tool. The qualitative findings of the second study showed that the domains-of-socialization approach and the daily life interactions of mother-child dyads were mostly consistent. The third study showed that the quality of parenting behaviors in different socialization domains were related to various child outcomes through emotion regulation and inhibitory control.

(tr)ultrasonik Titreşim Destekli Frezelemenin Işlenmesi Zor Süper Alaşım Havacılık Malzemelerinde Nanoakışkan Minimum Miktar Yağlama Yöntemi ile Birlikte Incelenmesi/(eng)ınvestigation On The Effects Of Multi-axis Ultrasonic Vibration-assisted Milling With Nanofluid Minimum Quantity Lubrication On Difficult-to-cut Materials Used İn Aerospace Industries
Due to the desired material properties in the aerospace sector, Ti-6Al-4V and Inconel 718 superalloys are commonly utilized. However, due to properties such as low thermal conductivity, high chemical interaction tendency, and resistance to wear, these materials pose significant challenges in machining processes, often characterized as "difficult-to-cut" materials. This project aims to experimentally investigate the combined use of Ultrasonic Vibration Assisted Machining (UVAM) and Nanofluid Minimum Quantity Lubrication (NMQL) techniques to improve the machining performance of Ti-6Al-4V and Inconel 718 superalloys, which are difficult-to-cut materials commonly employed in the aerospace sector. Within this scope, various cooling methods including conventional machining with UVAM, dry cutting with NMMY, conventional cutting fluid, and pure-MQL are comparatively studied, and the obtained results are analyzed. Three different nanofluids, namely Al2O3, CuO, and Al2O3-CuO (hybrid), are prepared and utilized in experiments when employing the NMMY technique. Machining performance criteria are determined as cutting forces, surface roughness, surface topography, surface texture, geometric accuracy, tool wear, and subsurface plastic deformation measurements. According to the results obtained, it is found that when UVAM and NMMY techniques are used together, the combination yields the highest efficiency in machining performance compared to other methods for both Ti-6Al-4V and Inconel 718 materials. Furthermore, among the NMMY conditions, the hybrid (Al2O3-CuO) usage provides the best results, followed generally by CuO and then Al2O3 added nanofluids. Based on the information and data obtained in this project, it is clearly evident that the yet underutilized UVAM and NMMY techniques, both separately and together, can be applied more efficiently in milling Ti-6Al-4V and Inconel 718 materials compared to traditional methods. This is anticipated to contribute to the aerospace manufacturing sector.

Synthesis, Characterization And Applications Of Various Aromatic Polythioureas Via Multicomponent Polymerization/çok Bileşenli Polimerizasyon Yöntemi ile Farklı Aromatik Politiyoürelerin Sentezi, Karakterizasyonu ve Uygulamaları
In recent years, multicomponent polymerization (MCP) method has attracted the attention of researchers due to its simple operation, high atom economy, high polymerization efficiency and high molecular weight of polymers without using catalyst under moderate conditions. In the MCP method used in the synthesis of different polythioamides and polythioureas, one of the reactants is aliphatic amines and aromatic amines are not used directly. Due to this reason, in polythioamide syntheses, it is seen that aromatic diamines do not react with alkynes in the presence of elemental sulfur and therefore they are converted firstly to aromatic diisocyanides and this increases the cost of synthesis. There is no study on the use of aromatic diamines directly in the synthesis of polythioureas. In the light of this information, it is aimed to use the MCP method which is thought to be an economic and effective method for the use of elemental sulfur and aromatic diamine directly to obtain well defined, functional and workable polymeric structures without using catalyst in the project. In the MCP method, diisocyanides which are more reactive than the dialkyne reactant used previously will be used. The reactivity of diisocyanides to aromatic amines was supported by literature data and preliminary studies performed by our group. In addition, elemental sulfur, one of the most abundant elements in the world, is a non-toxic and stable solid under normal conditions and is an inexpensive substance that is readily available even at high purity grades. The use of aromatic diamines directly with elemental sulfur is very interesting in terms of practical, cost-effective and synthetic compatibility. With the use of aromatic diamines in the MCP method, the gateway for the synthesis of different polythioureas will be further expanded. For this purpose, the synthesis of 10 different polythioureas shown below will be carried out and characterization of the obtained products (NMR, FTIR, GPC, SEM, UV-Vis, DSC, TGA) will be performed. The data obtained will be examined comparatively with the methods used before for the synthesis of polythioureas. Due to today's polluted environment and limited energy reserves, it becomes important to develop highly efficient renewable technologies, green energy sources and environmentally friendly methods for environmental remediation and energy production. In this direction, hydrogen production becomes so important in the field of energy. In addition, the removal of heavy metals found in nature and organic matter in waste water is of great importance in environmental remediation. From this point of view, the preparation of nanocatalysts that will allow hydrogen production and removal of organic substances and materials that provide heavy metal removal attracts the attention of scientists. Thanks to the thiourea functional groups in the structure of different polythioureas to be synthesized by the MCP method, it can be used in mercury treatment (due to the ability of the thiourea groups and mercury ions to be complex) as well as to be used as support materials for the production of silver, palladium and copper nanoparticles. In this respect, firstly mercury removal capacity of the prepared polymers will be investigated. Then, the polymer-metal nanoparticle hybrid materials (4 different structures, polymer/AuNPs, polymer/AgNPs, polymer/CuNPs and polymer/PdNPs)) will be obtained by adding gold, silver, copper and palladium nanoparticles (separately) onto the polymer having the highest metal ion-holding capacity. The stability, catalytic activity and the effect of the interaction on the catalytic activity of the polymer/metal nanoparticle hybrid materials will be investigated in hydrogeneration from amine borane and photocatalytical removal of dye molecules founded in waste waters, respectively.
Donör-akseptör Düzeninde Yeni Bir Bileşik Grubununtasarımı, Sentezi ve İletken Polimerlerinin Uygulama Alanları
Donor-acceptor-based electrochromic polymers, unknown in the literature, were synthesized and the optical and electrochemical properties of these materials were examined. In this study, in which both the donor effect and the acceptor effect were examined, soluble and processable materials with colors such as green, blue, cyan and black, although very few in number in the literature, were synthesized which are indispensable for their application areas. Necessary characterization studies have been carried out for the anticipated technological applications.
Synthesis and Applications of New Conjugated Polymeric Materials Based on Carborane
Combination of conjugated polymers and carborane units under the same roof was taken place recently, for the first time in 2003. In very few number of studies in the literature, it was reported that carborane units gave thermal, mechanical, optical and electrochemical stability to the condujugated polymers. In this study, in order to overcome the problems faced by the industrial field of conjugated polymers (insolubility, thermal, mechanical, optical and electrochemical instability, etc.) the inorganic and organic units will be melted in the same pot for producing new carborane based polymeric materials. In the first two years of the project, initially carborane based electron donor-acceptor-donor (D-A-D) type new inorganic-organic hybrid monomers will be designed and synthesized and then soluble conjugated polymers (low band gap, reversible electronic and optical properties, n- and/or p-type doping behavior, fast switching of various redox states and different colors and environmetally and thermally stable novel florescent conjugated polymers) will be tried to obtain by use of electrochemical and chemical methods. While alkyl substituted 3,4-propylenedioxythiophene and carbazole units will be used as D unit, carborane units will be used as A unit. Tetrabutylammonium salts (perchlorate, tetrafluoroborate and hexafluorophosphate) as the supporting electrolyte and acetonitrile, dichloromethane and/or propylene carbonate will be used as the solvent in the electrochemical polymerization. For the chemical polymerization, Stille Coupling, anhydrous FeCl3 and / or CuI oxidant and/or Yamamoto type Ni (0) dehalogenation polymerization techniques will be used. After the investigation of the electrochemical, optical and thermal properties of the obtained polymeric materials, studies for the industrial and technological applications (electrochromic devices and light emitting diodes (LEDs)) will be done at Atılım University and METU by experienced teams in the last two years of the project. When the materials designed in the project are moved successfully to the industrial fields such as electrochromic devices and LED applications, it will be brought to a solution to an industrial problem by using carborane chemicals. As a result, it will be the primary purpose and goal of our project to overcome the problem faced by industrial areas (electrochromic devices and LEDs) with the products based on special carboranes, which can be synthesized in our country.

Design, Synthesis, Properties and Applications of Novel Processable Luminescent and Redox Active Compounds
Luminescence is the emission of electromagnetic radiation (in ultraviolet (UV), visible (Vis) or infrared (IR) regions) with no or little heat, which is produced by the transition of an electronically excited state intermediate generated by the application of an external stimuli to a lower (ground) state in order to release the excess energy. If the electronically excited state returns to the ground state from the lowest singlet excited state, it is called fluorescence or if it returns from the triplet excited state, it is called phosphorescence. The light emitted may be in UV and Vis regions as well as in IR region. Luminescent compounds have recently attracted considerable attention due to their practical applications in bio- and nanotechnological as well as materials sciences as chemosensors, electron and/or energy transfer systems, imaging agents, molecular machines and devices, molecular logic gates and so on. For that reason, the design, synthesis and characterization of novel luminescent compounds are highly concerned by first the synthetic organic chemists and as well as other communities all around the world. Herein, luminescent and redox active novel compounds (1-3) were designed, synthesized and characterized spectroscopically (UV-Vis, luminescence-fluorescence, FTIR, NMR, mass spectroscopy, combustion analysis, cyclic voltammetry). Furthermore, some applications of these novel compounds in analytical and/or material science (e.g. in forensic science, chemosensors) were investigated. In the last step of the work, these novel compounds were polymerized to give the corresponding polymeric materials, which were also characterized by spectroscopic methods.
