Opis:
The aim of this study was to evaluate the efficacy of electroacupuncture in acute and chronic phases of radial and ulnar nerve injuries in histopathological, immunohistochemical and biochemical aspects. In the study, the rabbits were divided into four groups namely acute nerve injury (ANI) group, chronic nerve injury (CNI) group, positive control (PC) group and negative control (NC) group. In the ANI, CNI and PC groups, damage was created on the nervus radialis and nervus ulnaris by applying pressure for 60 seconds using a hemostatic forceps under anesthesia. No damage was created in the NC group. Fifteen sessions of electroacupuncture were applied to the rabbits in the ANI, CNI, and NC groups every other day using LI-4 (Large Intestine Meridian-4, He Gu), LI-10 (Large Intestine Meridian-10, Shou San Li), LR-3 (Liver Meridian-3, Tai Chong), and ST-36 (Stomach Meridian-36, Zusanli) electroacupuncture points. Electroacupuncture was not applied to the rabbits in the PC group. Decapitation was performed under general anesthesia at the end of electroacupuncture applications. After the euthanasia procedure, the samples obtained were evaluated for histopathological, immunohistochemical and biochemical parameters. In conclusion, degenerative foci in the treatment groups were found to be fewer than in the PC group whereas NGF and S-100 immunoreactivity were higher in the treatment groups than in the PC group. Whereas no statistically significant difference was observed between the treatment groups and the NC group in terms of oxidative stress factors, there was a statistically significant difference between the treatment groups and the PC group. In light of all these data, we have concluded that electroacupuncture is an effective treatment method for peripheral nerve injuries.

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.

Opis:
Iodine is an essential element for the production of thyroid hormones. In recent years, it has been suggested that excessive consumption of iodine may play a role in the pathogenesis of papillary thyroid cancer (PTC). In addition, studies have suggested that high iodine consumption is an important risk factor for the formation of a BRAF mutation in the thyroid gland. A prospectively designed study included 132 cases scheduled for thyroidectomy for various reasons. Urine iodine levels of all patients were examined before the operation. The iodine excretion levels of the patients were grouped according to the median urinary iodine concentration determined in community screenings (those with <100 µg L-1 low iodine excretion, those with 100-199 µg L-1 normal iodine excretion, those with 200-299 µg L-1 high iodine excretion). Patients were divided into 3 groups according to the post-operative pathology results. As a result of thyroid histopathology, benign (n: 44), PTC (n: 88) (BRAF (+): 44 and BRAF (-): 44) cases were included in the study. BRAF mutations in patients diagnosed with PTC were evaluated using the “Real Time PCR Melting Curve Analyzer” method. The relationship between urinary iodine excretion levels and clinical, histopathological and BRAF positivity was examined. In our study, no difference was found in urinary iodine excretion between patients with and without PTC. Hashimoto’s thyroiditis was observed more frequently in patients with PTC (p=0.023). In addition, Hashimoto’s thyroiditis was statistically more frequently detected in the BRAF (-) group compared to the BRAF (+) and control group (p=0.034). Despite studies suggesting that high iodine consumption is important in PTC pathogenesis, we did not find a relationship between the mutation and iodine consumption, which plays an important role in the development of PTC.

Growth kinetics of boride layers in AISI H13 steel was investigated using the pack boriding method at temperatures of 1073, 1173 and 1273 K (800°C, 900°C and 1000°C) for periods of 2, 4 and 6 h with nano-sized boron (NB) and micron-sized Ekabor II powders as boriding agents. The total thickness of the boride layer (including both FeB and Fe2B) after boriding at 1273 K (1000°C) for 6 h was 103.8 μm and 96.5 μm for the NB and Ekabor II specimens, respectively. X-ray diffraction analysis of the boride layers on the surfaces borided with NB and Ekabor II revealed the presence of FeB and Fe2B phases with sawtooth morphology. The FeB/Fe2B volume ratio was higher in the specimens borided with NB. The thickness of the boride layer (FeB + Fe2B) increased with the increasing boriding temperature and time. The FeB layer in the NB specimen displayed a (002) preferred orientation.

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:
In this study, variations in permeability of a gold ore by nut shell addition was studied. Ore particle size, nut shell size and volume fraction in the ore were the parameters investigated. Permeability is an important issue in heap leach operations considering the processing duration. Particularly below 6 mm particle size permeability is greatly hampered. Turkey is the leading country in the world in hazelnut production. Therefore, considerable amounts of nut shell are obtained as a by-product. Incerase in the permeability of a finely crushed ore will obviously enable an increase in the leaching efficiency. The finer the particle size the more the liberation of gold is yet the permeability is lower. Therefore, this study focuses on the possibility of improving the permeability of ore heaps with nut shell addition. Optimum amount of nut shell which should be added to the ore was found to be 5% by volume. It was found that the permeability of ore crushed below 2.36 mm considerably increased by the addition of nut shell below 18 mm.

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.

Opis:
In the present work, Cu and Ni nanofluids were synthesized using the pulsed wire evaporation (PWE) method in the different aqueous medias, namely (ethanol and ethylene glycol), and the effects of the aqueous media on the dispersion state, stability, and particle size of nanoparticles were studied. The size and morphology of synthesized nano-particles were investigated by transmission electron microscopy (TEM). Also, the dispersion stability of the nanofluids was evaluated by turbiscan analysis. The TEM results showed that the nano-particles were spherical in shape, and the average particle size was below 100 nm. The average particle size of the Cu nano-particles was smaller than that of Ni, which was attributed to a difference in the specific sublimation energy of the elements. Moreover, ethylene glycol (EG) exhibited higher suspension stability than ethanol. Finally, the dispersion stability of Cu@EG displayed the highest value due to lower particle size and greater viscosity.

Opis:
Hydroxyapatite (HA) constitutes the mineral component of the hard tissues such as bone and teeth. HA is a bioactive ceramic material and can form biochemical bonds with tissues. It is possible to produce HA powders either from natural sources or by using synthetic chemicals. Wet chemical precipitation technique is an ideal method to practically and economically synthesize HA powders. Calcium hydroxide (Ca(OH)₂) and ortho-phosphoric acid (H₃PO₄) solutions were used as the calcium and phosphorus sources to obtain the HA powders. Acid-alkaline reactions between starting materials were carried out at three different reaction temperatures (room temperature, 50-60°C range and 70-80°C range) which may affect the microstructure of the produced powders. The procedure of HA powders preparation from natural sources consists of several steps: in the order of deproteinization of bovine bones in NaOH, washing the deproteinized bovine bones, calcination of the washed bones, and grinding the calcined bones, respectively. In this study, HA powders derived from bovine bones and HA powders obtained through the wet chemical precipitation method were compared in terms of their chemical, microstructural and molecular bonding properties by applying various characterization techniques such as X-ray diffraction, scanning electron microscope-energy dispersive spectroscopy, and the Fourier transform infrared spectroscopy.

Opis:
In order to make a contribution to the reduction of raw material costs, in the present study the effect of reused cotton fibres on the quality of conventional ring and OE-rotor yarns was investigated. In the yarn production, three different waste fibres were taken from a cotton yarn production line and blended with primary cotton fibres at five different levels varying from 5% to 40%. In literature, studies have concentrated on the usage of recovered waste fibre in OE-rotor yarn production. However, to date there has been limited extensive andcomparative research on the effect of recovered fibre quality on different yarn properties to determine the possibility of high-quality yarn production from reused fibres. In the study, we focused on the effect of different waste types as well as the amount of waste in the blends on the properties of different yarn types.
W celu obniżenia kosztów produkcji przeprowadzono badania dotyczące ponownego wykorzystania włókien bawełnianych na jakość konwencjonalnych przędz obrączkowych. Do produkcji przędzy użyto trzech rodzajów włókien odpadowych i wymieszano je z wcześniej nieużywanymi włóknami bawełnianymi w ilości od 5 do 40%. W literaturze można znaleźć wiele publikacji koncentrujących się głównie na wykorzystaniu odzyskanego włókna odpadowego w produkcji przędz, jednakże przeprowadzono dotychczas niewiele badań porównawczych dotyczących wpływu jakości odzyskanych włókien na różne właściwości wytworzonych z nich przędz. W pracy skoncentrowano się na wpływie różnych typów odpadów, jak również ilości odpadów w mieszankach na właściwości różnych typów przędzy.

In this study, machinable glass-ceramics were produced from vermiculite and K₂CO₃, SiO₂, Al₂O₃ and MgF₂ as additives by melting process. The starting materials were mixed together and milled in a mill with alumina ball for 2 h. The mixed powders were melted by aluminum crucible at 1500°C. The melted glass was cast into graphite mold, and then it was exposed to crystallization heat treatment for glass-ceramic transformation. The glass-ceramic samples were characterized with X-ray diffraction analysis, scanning electron microscopy, mechanical tests such as hardness, fracture toughness and machinability test. The results indicate that machinability properties can be obtained from vermiculite based glass-ceramic with some additives.
