    Opis:
    At the present day, the duration of product life is much shortened as a result of the customer demands changing rapidly and intensive competition. The customary design and production technologies have remained incapable against such hard conditions and consequently new concepts and methods have arisen. One of those concepts is “Mechatronics Engineering”. The mechatronics design method is based on an integrated approach to form the design eventuating in mainly match-purpose products instead of sequential design. The basic combination of the mechatronics approach is based on the usage of system model and simulation through prototype stages. The first step in development of the mechatronics systems is analyzing customer demands and the technical frame in which the system is combined. Generally the Mechatronics Design Process is rounded up the under seven mean headings. At the present day, remote controlled robotic systems are required for various purposes such as research, education, commerce etc. The target in this study is to design a remote controllable robot equipped with control capability with a robotic arm, to be developed following the Mechatronics Design Processes and used for the purpose of bomb defusing.

    Opis:
    In this study, an artificial neural network application was performed to tell if 18 plates of the same material in different shapes and sizes were cracked or not. The cracks in the cracked plates were of different depth and sizes and were non-identical deformations. This ANN model was developed to detect whether the plates under test are cracked or not, when four plates have been selected randomly from among a total of 18 ones. The ANN model used in the study is a model uniquely tailored for this study, but it can be applied to all systems by changing the weight values and without changing the architecture of the model. The developed model was tested using experimental data conducted with 18 plates and the results obtained mainly correspond to this particular case. But the algorithm can be easily generalized for an arbitrary number of items.

    Opis:
    In this study, tungsten-vanadium carbide-graphite (W-VC-C) and tungsten-vanadium carbide-titanium carbide-graphite composite (W-VC-TiC-C) materials were investigated against Co-60 gamma radioisotope. The composite materials which are used in advanced technological studies and high temperature applications in many various fields especially in the areas of fission and fusion armor materials were produced by mechanical alloying method as in two groups. One of them include 93% tungsten (W), 6% vanadium carbide (VC) and 1% graphite (C) also which has three different alloying times (6-12-24 h). Other group of the samples was composed of 91% tungsten, 6% vanadium carbide (VC), 2% titanium carbide (TiC) and 1% graphite (C) also which has three different alloying times (6-12-24 h) and sintered at 1750°C. Co-60 gamma radioisotope source and gamma transmission technique were used in the experiments to investigate the properties of the composite materials. The mass attenuation coefficients of the samples were determined by using experimental results and theoretical mass attenuation coefficients were calculated from XCOM computer code. It can be concluded that increasing the tungsten ratio causes higher mass attenuation coefficient and the composite materials have provided us benefits better than lead for radiation gamma shielding.

The composite materials were produced via mechanical alloying method in two groups; one of them includes 93% tungsten (W), 6% vanadium carbide (VC) and 1% graphite (C) which was synthesized during three different alloying times (6, 12, 24 hours). Other group of the samples were composited as 91% tungsten, 6% vanadium carbide (VC), 2% titanium carbide (TiC) and 1% graphite (C) which has also three different alloying times (6, 12, 24 hours). Gamma transmission technique was used in the experiments to investigate the gamma attenuation properties of the composite materials. Linear and mass attenuation coefficients of the samples were determined in the experiments and theoretical mass attenuation coefficients were calculated using widely acknowledged XCOM computer code. The experimental mass attenuation coefficients and calculated theoretical results were compared and evaluated with each other. Results showed that gamma attenuation coefficients of the composite materials dependent on alloying time. It can be concluded that increasing the tungsten ratio causes higher linear attenuation coefficient which decreases with increasing gamma energies.

    Opis:
    The aim of this study was to compare the effect of flunixin meglumine (FM) and meloxicam (M) on postoperative and oxidative stress in ovariohysterectomized bitches. Twenty four bitches were divided into three groups (n=8 in each) and treated during premedication as follows: FM (2.2 mg/kg, iv, Fluvil, Vilsan, Turkey), M (0.2 mg/kg, sc, Maxicam, Sanovel, Turkey) or 0.9% saline (1 ml, iv, IE, Turkey) - control (C) group. The concentrations of serum cortisol, nitric oxide (NO), malondialdehyde (MDA), antioxidant potential (AOP) and glutation (GSH) were measured in blood samples collected during incision (0 h), closure of incision line (0.5 h) and 1, 2.5, 12 and 24 hours after incision. It was observed that cortisol level was higher at 0.5, 1 and 2.5 h in group C (p < 0.05), 0.5 h in group FM (p < 0.001), and 1 and 2.5 h in group M (p < 0.01), as compared to that determine at 0 h. Group C showed higher cortisol level during 0.5 h (p < 0.05) than that found in the other groups. Group FM displayed lower levels during 1 h (p < 0.01) and 2.5 h (p < 0.05) as compared to those observed in other groups. Concentrations of MDA, AOP and GSH between all the groups did not show any significant differences. MDA level was higher at 0.5 and 1 h in groupM (p < 0.05) than that found in group C and it was the lowest at 2.5 h in group C (p < 0.05). AOP was higher at 2.5 h in group FM and M (p < 0.05) than that observed in group C, and at 12 and 24 h in group M than that found in group C and FM. GSH did not show any significant differences between the groups. NO level in group FM after 12 h was higher (p < 0.05) than that at 0.5, 1 and 24 h. Moreover, NO level was lower at 0.5 (p < 0.01), 1 (p < 0.05) and 24 h (p < 0.05) in group FM than that observed in group C and M. In conclusion, flunixin meglumine decreases cortisol and NO levels more efficiently than meloxicam. Therefore, it is suggested that postoperative stress following ovariohysterectomy may be prevented by flunixin meglumine in bitches.

    Opis:
    The plasma transferred arc (PTA) process was used for developing wear resistance of AISI 430 steel substrate. Appropriate quantities of FeCrC, FeW and FeTi powders were combined to create conditions that synthesized M7C3 particles into reinforced Fe-based composite surface coating. The phase transformations on new created coated surfaces were comprehensively examined by using a combination of scanning electron microscopy (SEM), microanalysis by energy dispersive spectrometry (EDS), X-Ray diffraction (XRD), microhardness and abrasive wear tests. The microstructure studies of the superficial layers of the coating revealed presence of a mixture of the dendritic phase structure of austenite (γ) and fine eutectic M7C3 carbides. The results show that; the concentrations of the elements (Cr, W, Ti) added as ferroalloys, the size of dendrites formed in the coated surface, the change of hardness of the coated surfaces, the carbide volume rate and thickness of the coating changed by the variation of the processing parameters (ratio of reinforcement particulates and heat input).
    Technika PTA została zastosowana jest do podwyższania odporności na zużycie podłoży ze stali AISI 430. Odpowiednie ilości proszków FeCrC, FeW i FeTi połączono w celu stworzenia warunków, w których syntetyzowane są cząsteczki M7C3 zbrojące powłoki kompozytowe na bazie Fe. Przemiany fazowe w nowo utworzonych powlokach zostały szczegółowo zbadane za pomocą kombinacji skaningowej mikroskopii elektronowej (SEM), mikroanalizy spektrometrią dyspersji energii (EDS), dyfrakcji rentgenowskiej (XRD), mikrotwardości i testów ścierania. Badania mikrostruktury wierzchnich warstw powłoki wykazały obecność mieszaniny struktury dendrytycznej austenitu (γ) i drobnych eutektycznych węglików M7C3. Wyniki pokazują, że: stężenie pierwiastków (Cr, W, Ti) dodanych jako żelazostopów, wielkość dendrytów utworzonych w powłoce, zmiany twardości powłoki, szybkość objętościowa węglików i grubość powłoki zmieniają się ze zmianą parametrów procesu (stosunek cząstek wzmacniających i mocy cieplnej).

Adhesive wear tests were carried out by using a tribometer in block-on-ring configuration (ASTM G77), in sliding conditions, without lubricants and in air. Tests were carried out at sliding speed of 1.6 m/s (511 rpm) and applied load values of 25, 50 and 75 N. Wear rate was calculated using weight loss per unit sliding distance. The results showed that, the friction force increases with the increasing load. It was found that the wear resistance of PA6 improved considerably after doping with CBC.

    Opis:
    Al-Ti intermetallic compounds were coated by electro-spark deposition. Commercially pure titanium (Cp-Ti) (grade 2) and aluminum rods were used as substrate and electrode materials, respectively. During the electro-spark deposition experiments the following pulse parameters in a group were used: pulse current amplitude, pulse duration and pause between the pulses of a pulse group with 100-300-500 A, 50-100 μs, and 100 μs, respectively. Al-Ti coatings having a thickness range of 15-30 μm were formed on the surface of titanium substrate using electro-spark deposition process. The coating properties such as the roughness and the thickness increased with increasing pulse duration and pulse current amplitude. The mass transfer coefficient decreased with increasing pulse current amplitude and pulse duration. The quality of the adhesion characters of the coatings, determined by Rockwell-C adhesion test, becomes worse from HF-2 to HF-4, due to increase of pulse current amplitude. Depending on the electro-spark deposition process parameters, the coating formed as AlTi or as layered structure consisting of AlTi+$AlTi_3$ when pulse current amplitude increases. The Al-Ti coatings include some micro cracks lying throughout the coating from surface to interface which is nature of this process. The maximum cross-sectional hardness of the coatings were in the range of 800-1150 HV.

    Opis:
    A new method was used in fixation of tibial bone fractures. Intramadular nailing (IMN) has been used into mid-diaphysis on left tibias of New Zeland rabbits (n = 5) via an in vivo work. To enable fixation of fracture, without causing too much screw damage on bone and avoiding malunion, nano- and micro-scale hydroxyapatite (HA) was coated at two ends (25 mm in length) of intramadular nails before implantation. After six weeks of survival period and sacrifizing, biomechanical tests and histopathologic examinations were executed. Such experiments have revealed that good stabilization and hence better fracture union for both treated IMN groups (NHA and MHA) over the standard IMN’. Pull-out tests showed the tensile strengths obtained to be significantly higher for the nano (NHA) and micro scale-MHA coated IMN compared to the uncoated standard IM nailing.

    Opis:
    In this study, we have focused on the role of silicon morphology on the hardness of eutectic Al–12 wt.% Si–0.5 wt.% Sb alloy solidified at different cooling rates. The alloys were produced by using induction melting, arc-remelting and melt-spinning techniques. The cooling rates of the alloys were determined as 0.5, 60 and ~105°C.s-1 for induction-melted, arc-remelted and meltspun alloy. The experimental results show that as the cooling rate increased the coarse silicon phase was substantially refined and its morphology altered from sharp need-like to round shape. Two exothermic peaks, attributed to precipitation and coarsening of silicon from supersaturated α-Al, were observed in the DSC curve of MS alloy. Vicker’s hardness of melt-spun alloy was found two times higher than those of IMed and ARed alloys. The lowest hardness of induction-melted alloy was ascribed to the lamellar morphology of silicon, yielding decohesive rupture. This result was confirmed by finite element analyzing.

    Opis:
    Blackberry and mulberry are main berry crops grown in Black Sea region mostly in humid shade forest areas and its important for local people’s diet and also important for the maintenance of their health and prevention of disease. Present study aimed to determine the content of vitamin C, organic acids (citric acid, tartaric acid, oxalic acid, malic acid, succinic acid, fumaric acid), sugars (glucose and fructose) and phenolic compounds (catechin, rutin, quercetin, chlorogenic acid, ferulic acid, o-coumaric acid, p-coumaric acid, caffeic acid, syringic acid, vanillic acid, and gallic acid), as well as antioxidant capacity (Trolox Equivalent Antioxi-dant Capacity, TEAC assay) in the wild grown blackberry and mulberry fruit. Among phenolic acids, chlorogenic acid was the predominant for all wild grown blackberries, white and black mulberries. The presence of oxalic acid was only detected in the wild blackberry genotype. As a result, the phytochemical recognition of the wild grown blackberry, black and white mulberries might contribute to forthcoming investigations for developing the efficiency of food industry.
    Czarna jagoda i morwa należą do głównych owoców jagodowych uprawia-nych w rejonie Morza Czarnego w wilgotnych cienistych obszarach. Są one też ważne w diecie lokalnych mieszkańców, dla utrzymania zdrowia oraz zapobiegania chorobom. Celem niniejszego badania jest określenie zawartości witaminy C, kwasów organicznych (cytrynowego, winowego, szczawiowego, jabłkowego, bursztynowego, fumarowego), cukrów (glukozy i fruktozy), związków fenolowych (katechiny, rutyny, kwercetyny, kwasów: chlorogenowego, ferulowego, o-kumarowego, p-kumarowego, kawowego, syryngowego, wanilinowego i galusowego), a także pojemności antyoksydacyjnej (pojemnośćprzeciwutleniająca wyrażona w równoważnikach, test TEAC) w owocach dziko rosnącej czarnej jagody i morwy. Dominującym kwasem wśród kwasów fenolowych dla wszystkich uprawianych czarnych jagód oraz białej i czarnej morwy był kwas chlorogenowy. Obecność kwasu szczawiowego była wykryta tylko w genotypie dzikiej czarnej jagody. Fitochemiczna analiza dziko rosnącej czarnej jagody oraz czarnej i białej morwy może zatem przyczynić się do kolejnych badań zmierzających do zwiększenia wydajności przemysłu spożywczego.

    Opis:
    This study focuses on the characterization and optimization of calixarene modified carbon nanotube thin films for gas detection. Calixarene molecules were synthesized individually by considering their functional groups to attract the gas. Calixarene modified carbon nanotube based sensors were fabricated using drop-casting method on a quartz crystal microbalance gold electrode. Carbon monoxide, carbondioxide, oxygen and dry air were used as active gases for adsorption process, while high-purity nitrogen gas was used for desorption process. The selectivity and sensitivity of calixarene modified carbon nanotube are investigated in detail. Our experimental results show that functional calixarene modified carbon nanotube coated quartz crystal microbalance sensors are very sensitive and selective to gas of $CO_2$ at room temperature operation.

    Opis:
    This study aimed to identify bacterial pathogens in milk samples from dairy cows with subclinical and clinical mastitis as well as to assess the concentrations of oxidant-antioxidant parameters [malondialdehyde (MDA), reduced glutathione (GSH), and total GSH levels] in both blood and milk samples. From a total of 200 dairy cows in 8 farms, 800 quarter milk samples obtained from each udder were tested in the laboratory for the presence of udder pathogens. Cultivated bacteria causing intramammary infection from milk samples were identified by Matrix-Assisted Laser Desorption/Ionization-Time of Flight (MALDI-TOF). In addition, from tested animals 60 cows were selected includıng 20 healthy cows that were CMT negative, 20 cows with subclinical mastitis (SM), and 20 cows with clinical mastitis (CM) for detection of MDA, GSH, and total GSH levels in blood and milk samples. Three hundred and eighty (47.5%; 380/800), 300 (37.5%; 300/800), and 120 (15%; 120/800) of milk samples, respectively were CMT positive or SM and CM, and those positives were cows from different farms. We observed that 87.4% (332/380), 25.3% (76/300), and 34.2% (41/120) of cows with CMT positive, CMT negative, and CM had bacterial growth. The most predominantly identified bacteria were Staphylococcus chromogenes (18.7%) obtained mainly from SM and Staphylococcus aureus (16.7%) as the most frequent cause of CM. According to our results, dairy cows with CM had the highest MDA levels, the lowest GSH, and total GSH levels in both blood and milk samples however, high MDA levels and low GSH levels in milk samples with SM were observed. Based on our results, lipid oxidant MDA and antioxidant GSH could be excellent biomarkers of cow’s milk for developing inflammation of the mammary gland. In addition, there was no link between nutrition and MDA and GSH levels.
