One of the oldest oilseed crops is sesame, which is mainly cultivated due to its valuable oleic/linolenic fatty acid ratio. The application of precise irrigation and fertilisation is crucial to ensure the continuity and productivity of sesame production, especially in arid and semi-arid regions. This study aimed to determine the effect of drip irrigation and nitrogen levels on sesame's oil and fatty acid composition. For this purpose, four nitrogen doses (N
0 : 0 kg ha−1 , N30 : 30 kg ha−1 , N60 : 60 kg ha−1 and N90 : 90 kg ha−1 ) and three different irrigation water levels (I50 , I75 and I100 , which correspond to 50, 75 and 100% evaporation levels from the evaporation of the Class A pan) were applied. The highest oleic acid content (43.06%) was obtained for the I75 N90 treatment. In the case of linoleic fatty acid, the greatest value (43.66%) was for I50 N0 treatment. The effects of irrigation and nitrogen doses on oleic acid and linoleic acid content were inverse of each other. An increase in applied irrigation water increased the linoleic acid content. However, it caused a decrease in oleic acid content. Increasing the nitrogen dose increased the oleic acid content and caused a decrease in linoleic acid content. Furthermore, this study showed that the I50 N60 treatment (50% Epan and a rate of 60 kg N ha−1 ) is the most effective for achieving high grain and oil yields in sesame cultivation. The results obtained provide practical guidance for farmers in sesame cultivation. [ABSTRACT FROM AUTHOR]- Published

This study was conducted to investigate the effects of different mixture ratios of sorghum (S) and cluster bean (CB) on fermentation parameters, nutritional composition, and gas-methane production of mixture silages. Five different mixture ratios (100%S, 75%S+25%CB, 50%S+50CB, 25%S+75%CB and 100%CB) were used in this study. Effects of mixture ratios on entire parameters were highly significant (p ≤ 0.01). Decreasing ADF and NDF ratios and increasing crude protein, ash and oil contents and condensed tannin levels were observed with increasing cluster bean ratios of the mixtures. However, cluster beans reduced WSC and lactic acid and increased pH, butyric acid and ethanol contents. The lowest Fleig score was obtained from cluster bean silage (100%CB). The lowest gas-methane production was obtained from cluster bean silage and the greatest ME and NEL values were obtained from sorghum silage (100%S). The best OMD values were obtained from sorghum silage and 75%S +25%CB mixture silage. The present findings revealed that a 50%S+50%CB mixture yielded high nutritional composition and good fermentation parameters. [ABSTRACT FROM AUTHOR]

- Abstract
The technical capability of proton exchange membrane fuel cell (PEMFC) offers an encouraging solution to produce sustainable and clean power. The pivotal part of the PEMFCs is the gas diffusion layer (GDL) which performs critical roles in providing a pathway for reactant and product. GDL electrically connects the catalyst layer to the current collector and conducts heat generated in the electrochemical reactions. The thermal conductivity as a transport property of the GDL affects heat transfer across the cell and the overall performance. In the current work, the impact of the isotropic GDL thermal conductivity ranging 1-100 W/mK at 0.4 and 0.6 V on the cell efficiency is studied computationally using ANSYS Fluent PEMFC module. The results indicate that an increase in the GDL thermal conductivity enhances the fuel cell current density considerably up to 20 W/mK and then the impact of the GDL thermal conductivity on the performance diminishes at 0.4 and 0.6 V. The power function provided a good fit with the calculated data. The maximum current density of 1.38 A/cm2 with the more homogeneous temperature distribution and lower temperature across PEMFC is obtained at 100 W/mK. Moreover, oxygen consumption and water production augments with higher thermal conductivity, especially the regions above the cathode current collector ribs.

This research was carried out to determine feed quality parameters of leaves and stems of different alfalfa genotypes. A total of 12 alfalfa genotypes was used as the plant material for the study. Alfalfa plants were harvested at the flowering stage. The plants were dried at 70°C and grinded in a hand-mill with 1 mm sieve for chemical analysis. In leaf, the acid detergent fiber (ADF) content of genotypes varied between 21.62 - 27.40%, the neutral detergent fiber (NDF) content between 33.98 - 39.95%, and crude protein content between 24.68 - 28.45%, whereas in stem ADF content of genotypes varied between 50.99 - 57.72%, NDF content between 66.96 - 76.79 %, crude protein content between 8.46 - 11.00%. The RFV ranged from 159.18 to 197.27% and 53.22 to 67.06% for leaf and stem respectively. The leaf to stem ratio of genotypes ranged from 0.72 to 1.60. Considering current results from different genotypes, genotype has a high effect on feed quality. In addition, the rate of leaf to stems is also effective on feed quality. While the protein ratio of the leaves was higher than the stems, the ADF and NDF contents were found to be lower than the stems. So, in the selection of alfalfa genotypes, attention should be paid to the leaf to stem ratio as well as the yield.

The aim of the current experiment was to determine the effect of harvesting stage on the potential nutritive value. Vicia cracca plant was harvested at three maturity stages (before flowering, flowering and seeding). Vicia cracca plants were dried at 70 °C and grinded in a hand-mill with 1 mm sieve for chemical analysis. Crude protein, crude oil, crude ash, condensed tannin, acid detergent fiber (ADF), and neutral detergent fiber (NDF) parameters were investigated as the chemical composition. Harvesting stage had a significant (p ≤ 0.01) effect on chemical composition. Dry matter, NDF and ADF contents were increased with advancing maturity whereas crude protein, crude oil, condensed tannin and crude ash contents were decreased. As a conclusion, the nutritive value of Vicia cracca plant decreased with increasing maturity. Vicia cracca hays harvested at three maturity stages were adequate in term of mineral content for ruminant. Therefore, the Vicia cracca plant can be harvested or grazed before flowering and flowering stages due to high crude protein, crude oil and low ADF and NDF.

Energy consumption in the world is increasing rapidly due to population growth and technological developments. Renewable energy sources have gained importance thanks to fossil fuel reserves being limited and their negative impacts on the environment. The design of blade geometry is crucial to enhancing the efficiency of wind turbines that convert kinetic energy in the wind, one of the renewable energy sources, into electrical energy. In this study, the effect of the change in the geometry of the lower surface of the NACA 63-415 airfoil used in wind turbines on aerodynamic performance was investigated numerically with the ANSYS Fluent CFD software. The experimental lift coefficient (CL) values for a range of angles of attack 0° to 20° at a Reynolds number of 1.6x106 number, were compared with the numerical CL values obtained using Spalarat Almaras and SST k-ω turbulence models. Since CL values obtained by the SST k-ω turbulence model fitted better with the experimental data, the calculations were performed using this model. In this study, NCAY10, NCAY20 and NCAY30 blade profiles were produced by reducing the dimensions of the lower surface of the NACA 63-415 airfoil by 10%, 20% and 30%, respectively. Numerical results showed that the new airfoils improved the aerodynamic performance compared to the NACA 63-415 airfoil and the maximum CL/CD values were obtained using the NCAY30 airfoil. It is thought that this study will contribute to the literature on enhancing the performance of the existing airfoils., Nüfusun artması ve teknolojik gelişmelere bağlı olarak dünyada enerji tüketimi hızla artmaktadır. Fosil yakıtların rezervlerinin sınırlı olması ve çevreye olumsuz etkilerinden dolayı yenilenebilir enerji kaynakları önem kazanmıştır. Yenilenebilir enerji kaynaklarından biri olan rüzgârdaki kinetik enerjiyi elektrik enerjisine dönüştüren rüzgâr türbinlerinin veriminin artırılmasında kanat geometrisin tasarımı önemlidir. Bu çalışmada rüzgâr türbinlerinde kullanılan NACA 63-415 kanat profilinin alt yüzeyinin geometrisindeki değişikliğin aerodinamik performansa etkisi ANSYS Fluent hesaplamalı akışkanlar dinamiği (HAD) yazılımı ile sayısal olarak araştırılmıştır. 1,6x106 Reynold sayısında, 0°-20° hücum açısı aralığında literatürdeki deneysel kaldırma katsayısı (CL) değerleriyle Spalarat Almaras ve SST k-ω türbülans modelleri kullanılarak elde edilen sayısal CL değerleri karşılaştırılmıştır. SST k-ω türbülans modeliyle elde edilen Cl değerleri deneysel verilere daha iyi uyum sağladığı için hesaplamalar bu modelle yapılmıştır. Bu çalışmada, NACA 63-415 kanat profilinin alt yüzeyinin boyutları % 10, % 20 ve % 30 azaltılarak sırasıyla NCAY10, NCAY20 ve NCAY30 kanat profilleri üretilmiştir. Sayısal sonuçlar yeni kanat profillerinin NACA 63-415 kanat profiline göre aerodinamik performansı iyileştirdiğini ve maksimum CL/CD değerlerinin NCAY30 kanat profili ile elde edildiğini göstermiştir. Bu çalışmanın mevcut kanat profillerinin performansını artırmada literatüre katkıda bulunacağı düşünülmektedir.

- Abstract
PEM fuel cell (PEMFC) is a potential candidate for future source of power used in different applications such as transportations, stationary and portable power. PEMFC consists of different parts including membrane, bipolar plate, flow channel, gas diffusion and catalyst layers. Membrane is one of the most important components of a PEMFC and its physical and geometrical features significantly affect PEMFC efficiency. In this paper, a three-dimensional, single-phase computational model has been improved to scrutinize membrane thickness effect on the PEM fuel cell performance using the ANSYS PEM Fuel Cell Module. Membrane thicknesses are in the range of a range of 0.0127 to 0.189 mm. The results reveal that a decrease in membrane thickness augments the current density at 0.4 and 0.6 V. The peak current density of 3.12 A/cm2 is achieved with 0.027 mm membrane thickness compared the model current density of 1.26 A/cm2 obtained by the model with 0.128 mm membrane thickness at 0.4 V. Oxygen consumption and water production also enhance with reducing membrane thickness at 0.4 and 0.6 V. However change thickness of the membrane has a negligible impact on impact pressure drop in the flow channel. It is found that optimization of membrane thickness are necessary for attaining high efficiency. Received: 07 September 2022 Accepted: 07 October 2022 Published: 26 October 2022

Bu makalede klasik Türk şiirinde yaşlılık algısının tespiti amaçlanmıştır. Yaşlılık, ihtiyarlık insan ömrünün kaçınılmaz sonlarından biri olarak birçok insanın yaşayacağı bir ömür dönemidir. Ömrü olan her bireyin başına gelecek bir hal olan ihtiyarlığın şairlerin gündemine gireceği şüphe götürmez. Klasik şiirimizde yaşlılığın nasıl karşılandığı, algılandığı ve değerlendirildiği sorusuna cevap aramak için her yüz yıldan ulaşabildiğimiz divanları taradık. Şairlerin bu hayat dönemi hakkında kullandıkları kelime ve mazmunları belirlemeye çalıştık. Tespit ettiğimiz beyitleri belli başlıklar altında inceledik. Hemen her asırdan şairlerin zaman zaman birbirleriyle örtüşen duygu ve düşünceleri dile getirdiklerini gördük. Bu yazının giriş bölümünde konunun bir kısa değerlendirmesi yapıldıktan sonra divanlarda yaşlılık için kullanılan isim ve sıfatlar ve şairlerin ömür tarifleri üzerinde duruldu. Makale giriş dışında dokuz bölüm halinde düzenlendi. Her bölümde şairlerden yapılan beyit alıntıları şairlerin yaşadıkları kronoloji dikkate alınarak verildi. Yaşlılığın hallerinin anlatıldığı üçüncü bölüm yazının en geniş kısmını teşkil etmektedir. Bunun dışında yaşlılıkla ilgili fiziki ve psikolojik yaklaşımları tespit etmeye çalıştık. Şairlerin gençlere tavsiyeleri ve yaşlıların dualarını almaları gibi hususlar kısaca verildi. Yazı kısa bir sonuç bölümü ile bitirildi. Nitel araştırma özelliğini taşıyan bu çalışmamızda dokümanter analiz yöntemini takip edilmiştir., This study aims to designate perceptions of old age in classical Turkish poetry. To be old is one of the periods in human life, which no one could avoid, thus when this time comes, it is compulsory. The old age is a topic that cannot go unnoticed in poetry. In order to answer the question how the old age in our classical poetry was evaluated, poetry books from all centuries, which we could find, were searched. The words and concepts which poets used about the old age have been studied. All couplets we recorded were classified under certain titles. We have seen that the poets share the same kind of feelings in almost every century. After a brief evaluation of the subject in the introduction section, the names and adjectives used for the old age and the definition made by poets for the old age were dealt with. The article was organized into nine sections except the introduction. In each section examples of couplets are given in accordance with poet’s chronological order. The section talking about various states of the old age is the longest one. In addition, we have tried to study physical and psychological approaches to the old age. Subjects such as advises by the poets to young people, and their gaining the prayers of the old were discussed briefly. The text culminates in a short conclusion. In this study, which has the characteristics of qualitative research, the method of documentary analysis was followed.

Klasik Türk edebiyatının en büyük şairlerinden biri olan Fuzûlî (ö. 963/1556) aynı zamanda âlim bir şahsiyetti. Ardından ilim ve hikmetle harmanlanmış birçok eser bırakmış, Türkçe, Farsça divanlarında Allah ve Hz. Muhammed (sav) konusunda türlü görüş, düşünce ve duygularını dile getirmiştir. Fuzûlî’yi Türk edebiyatının en büyük simalarından biri yapan husus sadece onun şiir alanındaki ifade kudreti değil, aynı zamanda derin bir tevhid coşkusu ve yüksek bir Peygamber sevgisi sahibi olmasıdır. Onu büyük şair yapan hususların başında bu sevda gelir. Bu yazıda şairin Türkçe Divanı’nda Tevhîd ve Hz. Muhammed (sav) konusundaki duygu ve düşünceleri incelenecektir. Tevhîd manzumesi edebiyatımızın en önemli manzumeleri arasında yer almıştır. Zengin muhtevası ve başarılı şiir dili ile ilgi çekmiş nazireleri yazılmıştır. Türkçe Divan’da üzerinde önemle durulan konulardan biri de Hz. Muhammed (SAV) sevgisidir. Fuzûlî na’t türünde kasîde ve gazeller kaleme almış, bu şiirleriyle çok sevilmiş ve okunmuştur. Özellikle Su Kasîdesi şaire önemli bir ün sağlamıştır. Şairin Tevhîd ve Hz. Muhammed (SAV) gibi İslâmî temel iki konudaki duygu ve düşünceleri ilgi uyandırmaya devam etmekte ilmi yazılara konu olmaya devam etmektedir., Fuzuli (death. 963/1556), who is one of the most prominent poets of the classical Turkish literature is at the same time a scholar, who left behind himself a legacy of many works blending knowledge and wisdom. In his divans written in Turkish and Persian he expressed his views, thoughts, and feelings on Allah and Hz. Muhammed (PBUH). What makes Fuzuli a great person is not only his power of expression in poetry, but at the same time his deep excitement of tawheed (unity of God) and his great love for the Prophet Muhammed (PBUH). In this article we will study Fuzuli’s sentiments and thoughts concerning tawheed and Hz. Muhammed (pbuh). His poem on Tawheed is one of the most significant poems in our literature. Due to the rich content and successful poetic langauge it has drawn attentions and been imitated many times. One of the topics emphasized greatly in his Turkish Divan was the love for Hz. Muhammed (PBUH). Fuzuli wrote many qasides and gazels in the form of naat (eulogy), which have become immensely popular. Especially his Su Kasidesi (Qaside of Water) brought to him a great fame. The poet’s sentiments and thoughts concerning the Unity of God and the love for Hz. Muhammed (PBUH), which are two fundamental Islamic topics still continue to catch the interests and become the subject of scientific writing.

The aim of the study was to investigate effects of different irrigation levels and nitrogen doses to chemical composition, in vitro gas and methane production of maize kernel for animal feeding. Three different nitrogen doses such as 100, 200 and 300 kg ha-1 N and irrigation levels such as 50%, 75% and 100% of depleted water were applied. The study was carried out under split plot for randomized complete block experimental design with three replicates during 2013-2014 seasons and irrigation levels were allocated in to main plots while nitrogen doses in to sub plots. The two-year results of the study showed that crude protein, crude ash and crude oil ratios and gas and methane production, metabolic energy (ME) and organic matter digestibility (OMD) were positively affected by increased level of water levels and nitrogen doses while acid detergent fiber (ADF) and neutral detergent fiber (NDF) and dry matter contents were negatively affected. It is clear that increased level of water and nitrogen positively contributed to quality of maize kernel for animal production but more researches are needed to explain how increased level of water and nitrogen result in higher level of gas and methane production.

In this study, aerial parts of dandelion were exposed to extraction by different solvents such as water, ethanol, methanol and glycerol and also their aqueous mixtures to compare the effect of extraction solvents on bioactive performance of the dandelion and also to show the effectiveness of hydroglycerolic extraction which is a green extraction process. Total phenolic content (TPC) and total flavonoid content (TFC) of the extracts were determined and also antiradical scavenging activities and antioxidant capacities of the samples were also evaluated. TPC and TFC of the samples ranged between 4.63-21.28 mg GAE/g and 1.16-14.38 mg CE/g, respectively. The highest TPC and TFC values were determined in aqueous extract of glycerol (75% w/w) compared to other solvents. Additionally, ABTS.+ and DPPH radical scavenging activity and ferric reducing capacity and antioxidant capacity values were determined for the extracts and the best solvent was also aqueous glycerol (75% w/w).

Hypericum perforatum is a widely used medicinal plant known that it has high bioactive performance due to its special biochemical compounds in its structure. The current study aimed to determine the optimum processing parameters of extraction conditions of bioactive constituents in H. perforatum by ultrasound application and its some bioactive performance. For this purpose, different processing variables namely sonication period (min), liquid/solid ratio and ethanol concentration (%) were selected to characterize the best conditions for extraction of H. perforatum. The statistical analysis results revealed that the most effective factor on the studied parameters was ethanol concentration and increment of ethanol level increased the characterized responses until a constant value. The constructed regression models fit very well with quite high determination of coefficients (R²>0.906). Total phenolic content was in the range of 39.54-63.55 mg GAE/g sample while total hypericin concentration ranged between 211.5-858.7 mg/kg. Multiple response optimization results revealed that the optimum extraction conditions would be at 47.6% ethanol concentration and 22.2 mL of liquid/solid ratio for 60 min ultrasonic process application. The results revealed that the optimized extraction conditions could be utilized for ultrasound extraction system by industrial application. [ABSTRACT FROM AUTHOR]

In this study, Origanum onites was used for the production of tincture, a hydroalcholic extract, and manufacturing conditions were optimized to determine the processing factor variable levels to increase the final quality of samples. For this purpose, response surface methodology study was applied and Box Behnken design was used for the optimization. Three factors were selected namely liquid/solid ratio, ethanol concentration and storage period for the preparation of samples. Total phenolic content, antiradical activity and efficient of concentration (EC50) values were determined to evaluate the bioactivity of tincture samples. It was observed that the total phenolic content of the tincture samples was affected by ethanol concentration and liquid/solid ratio. Total phenolic contents of tincture samples were in the range of 964.1-7020.8 mg GAE/ L samples while the efficient concentration (EC50) ranged from 44.88 to 89.56. Increase of solid level increased the bioactivity values of samples, but this increment decreased the tincture yield significantly. Optimization results showed that the highest total phenolic content would be at 50% ethanol concentration, 6 ml ethanol level which means the liquid/solid ratio is 1:5 and 15 days storage for the tincture samples. Bu çalışmada, bir hidroalkolik ekstrakt tipi olan tentür üretimi amacıyla Origanum onites bitkisi kullanılmış ve son ürün kalitesini artırmaya yönelik olarak üretim şartlarını optimize etmek üzere proses faktör seviyelerinin belirlenmesi amaçlanmıştır. Bu amaçla, optimizasyon işlemi için tepki yüzey yöntemi tabanlı Box-Behnken deneme tasarımından faydalanılmıştır. Örneklerin hazırlanması amacıyla sıvı/katı oranı, etanol konsantrasyonu ve depolama süresi faktör olarak seçilmiştir. Tentür örneklerinin biyoaktif özelliklerinin belirlenmesi amacıyla toplam fenolik madde miktarı, antiradikal kapasite ve EC50 değeri hesaplanmıştır.Sıvı/katı oranı ve etanol konsantrasyonunun örneklerin toplam fenolik madde miktarı üzerinden etkili olduğu görülmüştür. Örneklerin toplam fenolik madde değerleri 964.1-7020.8 mg GAE/ L, EC50 değerleri ise 44.88-89.56 aralığında değişim göstermiştir. Örnek konsantrasyonunun artışı toplam fenolik madde miktarını artırırken, bu artış tentür veriminde düşüşe yol açmıştır. Optimizasyon sonuçları en yüksek toplam fenolik madde miktarının, %50 etanol konsantrasyonunda, 1:5 katı/sıvı oranında, 15 günlük depolama süresi sonunda elde edilebileceğini göstermiştir.

This study was conducted to investigate the possible silage of stay-green sorghum genotypes using GT biplot analysis. Following the grain harvest, 41 sorghum genotypes were chopped to make silage. Biochemical analyses were performed after 60 d of silage. The results revealed that green herbage yields varied between 13.40-65.96 t ha−1, pH between 3.92-4.25, dry matter ratios between 24.26-35.83%, crude protein ratios between 3.44-7.03%, acid detergent fiber (ADF) ratios between 27.46-52.01%, neutral detergent fiber (NDF) ratios between 40.80-69.12%, crude ash ratios between 5.8915.14%, lactic acid contents between 1.657-4.914%, and propionic acid contents between 0.000-0.247%. Methane production values varied between 14.15-21.80%, gas production between 18.51-47.36 mL, metabolic energy (ME) between 6.68-11.67 MJ kg−1 DM, and organic matter digestibility (OMD) between 47.20-89.93%. According to GT biplot analysis, there were positive correlations among ADF, NDF and DM; among methane, ME, OMD and gas-methane production; and among acetic, butyric and propionic acids, pH, ash and protein contents. There were negative correlations among gas production, ADF, and NDF and among herbage yield, crude protein, organic acids, pH and crude ash. Among the genotypes, Sugargraze was prominent with herbage yield, while genotypes G4 and G3 were prominent with crude protein. Considering all parameters, genotype G20 seemed to be the ideal genotype. Although some silage samples had low silage and nutritional characteristics, others yielded values close to or even higher than full sorghum silage. These varieties can constitute a quality roughage source for livestock in winter. Further breeding research on stay-green genotypes may provide significant contributions to plant and livestock production activities. Resumen El objetivo del presente estudio es investigar las posibles ensilajes de genotipos de sorgo que tienen alta tasa de supervivencia del tallo y de las hojas después de la cosecha. Después de cosecha del grano, 41 genotipos de sorgo fueron picados para preparar ensilajes. Los análisis bioquímicos se realizaron después de 60 d de ensilaje. De acuerdo con los resultados obtenidos en el estudio; rendimiento de trigo verde varía entre 13.40-65.96 t ha−1, pH 3.92-4.25, proporción de materia seca entre 24.26-35.83%, proporción de proteína cruda 3.44-7.03%, los ratios de ADF entre 27.46-52.01%, los ratios de NDF entre 40.80-69.12%, los ratios de cenizas en bruto entre 5.89-15.14%, ácido láctico entre 1.657-4914%, ácido propiónico entre 0.000-0.247%. Los valores de producción de metano variaron entre 14.15-21.80%; Producción de gas entre 18.51-47.36 mL, energía metabólica (ME) entre 6.68-11.67 MJ kg−1 MS y digestibilidad de materia orgánica (DMO) entre 47.2089.93%. Aunque algunos genotipos tienen características de calidad de alimentación baja, la mayoría de los genotipos tienen características cercanas al ensilaje entero y están en el grupo de calidad de forraje para animales en invierno. Otros trabajos de mejoramiento de los genotipos que permanecen siempre verdes pueden producir contribuciones significativas a las actividades de producción vegetal y ganadera.

Dizel motorlarda tutuşmanın neredeyse yakıt püskürtülür püskürtülmez gerçekleşmesi yakıtın eşit derecede yayılmasını engellediğinden oksijenin zengin olduğu kısımlarda NOx ve yakıtın zengin olduğu kısımlarda is partikülleri oluşmaktadır. Sıkı emisyon düzenlemeleri nedeniyle özellikle dizel motorlarda yanma verimini artırmak ve egzoz gazı kirleticilerini azaltmak için son yıllarda deneysel ve sayısal çalışmalar yapılmaktadır. İçten yanmalı motorlarda yanma verimini artırmanın bir yolu emme portu, emme supabı ve yanma odası geometrisinde değişiklikler yaparak silindir içinde swirl, tumble ve squish gibi düzenlenmiş akımlar üretmektir. Bu yöntemlerde silindir içinde üretilen akımlar sıkıştırma stroku sonunda küçük ölçekli çevrilere dönüşerek türbülans şiddetini artırdığından hava-yakıt karışımının homojenliğini ve yanma hızının iyileşmesini sağlarken silindir içindeki yanma emisyonunu azaltmaktadır. Bu çalışmada direkt püskürtmeli (DP) dizel motorda bir çevrim boyunca silindir içindeki düzenlenmiş akışların yanmaya ve emisyona etkisi ANSYS WORKBENCH programı kullanılarak Hesaplamalı Akışkanlar Dinamiği (HAD) yöntemleriyle araştırılmıştır. Emme ve egzoz portları ve supabları, silindir ve piston gibi parçalar üretilmesi ve bu parçaların montajı SOLIDWORKS programıyla yapılmıştır. ANSYS WORKBENCH platformundaki dinamik sayısal ağ yöntemleriyle supab ve piston gibi parçaların hareketi sağlanmıştır. Türlerin taşınımı ve kimyasal reaksiyonların türbülansla etkileşimini sağlayan girdap-sönümlenme (eddy-dissipation) modelleri birlikte uygulanarak yanma modellenmiştir. Yakıt damlacıklarının birincil ve ikincil parçalanmasında sırasıyla katı koni (solid cone) enjeksiyon tipi ve Kelvin-Helmhotz Rayleigh-Taylor modeli kullanılmıştır. Yanma odasındaki NOx ve is emisyonlarının oluşumu sırasıyla genişletilmiş Zeldovich Mekanizması ve bir adımlı Khan ve Greeves modeliyle analiz edilmiştir. RNG k-ɛ türbülans modeliyle motorun yanma ve emisyon analizi yapılmıştır. Silindir içindeki akışı iyileştirmek için emme kanalı geometrisini değiştirme, emme kanalına helisel türbülatör yerleştirme ve piston oyuğunu şekillendirme olmak üzere üç farklı yöntem uygulanmıştır. Bu çalışmadaki üretilen tüm konfigürasyonların sıkıştırma oranları modellenen motorla aynıdır. Sayısal sonuçlar standart konfigürasyonla 1,3 olarak elde edilen swirl oranının 9,6 olarak 3/4 adım uzunluğundaki (PL) helisel türbülatörde (HT) en fazla arttığını göstermiştir. 3/4 PL helisel türbülatör 79 bar olarak yanma odasındaki basıncı da standart konfigürasyona göre % 7 artırmıştır. Fakat 3/4 PL helisel türbülatörüyle sıkıştırma strokunda üretilen negatif iş, net işi azalttığından 3/4 PL-HT konfigürasyonu indike termal verimi iyileştirmede etkili olamamıştır. Buna karşın 3/4 PL helisel türbülatörü emme strokunda silindir içine giren oksijen miktarını düşürdüğünden egzoz subapı açıldığında bu türbülatördeki NO emisyonu standart konfigürasyona göre % 3 azalmıştır. Bu çalışmada türbülans kinetik enerji en fazla 43,50 m2/s2 olarak emme kanalının saat yönünün tersi yönde 30º bükülmesiyle (-30B) üretilen konfigürasyonda elde edilmiştir. Bu nedenle standart konfigürasyona göre -30B konfigürasyonunda indike termal verim % 2,3 artmıştır. -30B konfigürasyonu is oksidasyonunda da etkili olmuştur ve egzoz supabı açıldığı anda is emisyonu 1,62 ppm olarak standart konfigürasyona göre % 75 azalmıştır. Bu çalışmadaki üretilen tüm konfigürasyonlara göre indike termal verim en fazla y ekseni yönünde iki yarım küreli (2YK-Y) piston oyuğu konfigürasyonunda elde edilmiştir. 2YK-Y piston oyuğunda indike termal verim standart konfigürasyona göre % 2,9 artmıştır. Diğer yandan, 2YK-Y konfigürasyonu silindir içi maksimum sıcaklığı standart konfigürasyona göre % 2,1 artırdığı için egzoz supabı açıldığı anda NO emisyonu % 10 artarken is emisyonu % 68 azalmıştır.Anahtar Kelimeler: Swirl, Tumble, Türbülans kinetik enerji, Yanma, Emisyon, HAD, ANSYS In the diesel engine, since ignition occurs almost as soon as fuel is injected, there is not enough time for dispersing fuel evenly and so oxygen-rich regions form NOx and fuel-rich regions form soot particulates. Due to recent emission regulations, many researchers have focused on the studies related to reduce exhaust emissions and improve combustion efficiency in diesel engines. One way to enhance combustion efficiency and reduce pollutant emission is generating in-cylinder flows such as swirl, tumble and squish by modifying geometry of intake port, intake valve and combustion chamber. In this method, the breakdown of the organized flows into small scale eddies end of the compression stroke augments turbulence intensity. Amplifying turbulence kinetic energy results in increasing homogeneity of air-fuel mixture and burn rate and decreasing amount of emission in the cylinder. In this study, the effect of the organized flow structures on combustion and exhaust emissios in a direct ignition (DI) diesel engine were investigated numerically through a full cycle by using Computational Fluid Dynamics (CFD) techniques in ANSYS WORKBENCH. The parts of geometry including ports and valves for the intake and exhaust, the cylinder and piston were produced and assembled using SOLIDWORKS. The necessary motion for valve and pistons was taked place by using dynamic mesh methods in ANSYS WORKBENCH platform. Species transport model in combination with eddy-dissipation model for turbulence-chemistry interaction was applied to simulate the combustion. Solid cone injection type and Kelvin-Helmhotz Rayleigh-Taylor model were used to describe primary and secondary break-up, respectively. NOx and soot formation in combustion chamber was analyzed by Extended Zeldovich Mechanisms and one-step Khan and Greeves model, respectively. RNG k-ɛ turbulent model was used for combustion and emission analysis. Mainly three methods such as changing the intake port geometry, shaping the piston bowl and fitting a helical turbulator inside the intake port were applied to amplify in-cylinder flow. In this study, compression ratios of all configurations were the same as the standart configuration. According to numerical results, for all configurations, 3/4 pitch length (PL) helical turbulator (HT) produced the maximum swirl ratio of 9,6 compared to 1,3 with the standart configuration at the end of the compression stroke. The maximum peak pressure in the combustion chamber of 79 bar was also achieved by 3/4 PL helical turbulator configuration which was about 7% over the standart configuration. But compared to standart configuration, the indicated thermal efficiency was not improved by 3/4 PL-HT configuration owing to the negative work produced by compression stroke decreasing the net work. However, 3/4 PL helical turbulator reduced NO emission of 3% compared with standart configuration when exhaust valve opened due to this turbulator decreasing amount of oxygen entering into the combustion chamber during intake stroke. In this work, the maximum turbulent kinetic energy of 43,5 m2/s2 was obtained in the first part of intake stroke by the configuration generated with bending of intake port 30º counter clockwise direction (-30B). As a result, -30B configuration increased the indicated thermal efficiency of 2,3% compared to standart configuration. -30B configuration was also efficient for soot oxidation and produced soot of 1,62 ppm with reducing of 75% compared to standart configuration at the moment exhaust valve opened. On the other hand, for all configurations, the highest indicated thermal efficiency was obtained by piston bowl with two hemispheres located y direction (2YK-Y) and 2YK-Y configuration increased the indicated thermal efficiency of 2,9 compared to standart configuration. Additionally, thanks to elevating the cylinder temperature of 2,1%, 2YK-Y piston bowl increased NO emission of 10% and diminished soot emission of 68% compared to standart configuration at the time exhaust valve opened.Swirl, Tumble, Turbulent kinetic energy, Combustion, Emission, CFD, ANSYS 156

Teknolojinin ve sanayileşmenin gelişmesi, nüfus artışı gibi nedenlerden dolayı çevre kaynaklarının tüketimi hızlanmış, çevrenin dengesi bozulmuş ve böylece çevresel sorunlar ortaya çıkmaya başlamıştır. Zamanla artan bu sorunlar insan yaşamını tehdit eder hale gelmiştir. Bunun sonucu olarak çevreye karşı suçlar düzenlenmeye başlamıştır. Bu kapsamda Türk Ceza Kanunu'nda da çevreye karşı suçlar düzenlenmiştir. Çalışma konusunu çevreye karşı suçlardan olan imar kirliliğine neden olma suçu oluşturmaktadır.5237 sayılı TCK yürürlüğe girene kadar kabahat olarak düzenlenen ruhsatsız yapılaşma, yeni TCK ile birlikte ilk defa suç olarak düzenlenmiştir. Maddede ruhsatsız veya ruhsata aykırı bina yapmak, ruhsatsız bina dolayısıyla başlatılan şantiyelere su, telefon ve elektrik bağlanmasına müsaade etmek ve ruhsatsız binalarda sınai faaliyete müsaade etmek suç olarak düzenlenmiştir.Çalışmada öncelikle çevreye karşı suçlarla korunan hukuki değere ilişkin tartışmalara yer verilerek çevre hakkının kapsamı ve mülkiye hakkı ve konut hakkı ile ilişkisi değerlendirilmiştir. Avrupa Birliği ve çeşitli ülke düzenlemelerinde çevrenin korunması ve imar kirliliğine neden olma suçunun tarihçesi verildikten sonra çevrenin ceza hukuku ile korunması gerekliliği üzerinde durulmuştur. Çevreye karşı fiillerin ceza hukukuna başvurulmadan önce idare hukuku kuralları ile korunduğundan çevreye karşı suçların idare hukukuna bağlılık sorunu kanunilik ilkesi ışığında incelenmiştir. Çalışmanın son bölümünde ise İmar Kirliliğine Neden Olma suçu unsurlarına ayrılarak detaylı bir şekilde değerlendirilmiştir.Anahtar Kelimeler: İmar, Çevre, Çevreye Karşı Suçlar, Kabahat, Suç, İmar Kirliliği, Çevre Kirliliği, Ceza Hukuku Improving technology and industry, population growth and rapid consumption of environmental resources have caused deterioration of natural balance. Hence, environmental problems have occurred. In course of time, environmental problems increased and became to threat human existence and other livings. As a result of this problem, environmental crimes are started to being established. In this concept environmental crimes were established in Turkish Penal Code as well. Subject of this work is crime of causingpollution of Zoning.Before effectiveness of TPC numbered 5237, unauthorized buildings were punished as misdemeanors. For the firs time it was established as a crime by the TPC. In this article, unauthorized buildings, no-permitting buildings, permitting to connect water, electricity and phone line to unauthorized constructions and also permitting industrial activities in unauthorized buildings are established as a crime.In this thesis, first of all legal goods of environmental crimes, concept of right of living within a healthy and balanced-environment, right to property and right to housing are evaluated. After European Union's and different countries' regulations are examined, historical ground of this crime and need criminal law for protection of environment is disgusted. Before criminal law interventions, the environment was protected via administrative sanctions. That's why environmental crimes are established connected with administrative law. In the last part of thesis, elements of CrimeOfCausingPollution of Zoning is in detailexamined.Keywords: Zoning, Environmental, Environmental Crimes, Misdemeanor, Crime, Zoning Pollution, Environmental Pollution, Criminal Law 270
