Opis:
Atomic lifetimes and energy levels were calculated using weakest bound potential model theory for $5 s^2 ns \text{ }^2 S_{1//2} (n \geq 6),$ $5 s^2 np \text{ }^2 P_{1//2}^0 (n \geq 5),$ $ 5 s^2 np \text{ }^2 P_{3//2}^0 (n \geq 5),$ $ 5 s^2 nd \text{ }^2 D_{3//2}^0 (n \geq 5),$ $5 s^2 nd \text{ }^2 D_{5//2}^0 (n \geq 5)$ series of the Rydberg states in neutral indium. The use of the quantum defect method and Martin's expression allowed us to supply lifetime values along by means of the series above. Some lifetimes and energy values not existing in the literature for high Rydberg states in neutral indium atom were obtained using this method. Our results nicely agree with the available experimental results and theoretical results.

Radiative lifetimes were calculated using weakest bound electron potential model theory for $4s^{2}$ ns $\text{}^{2}S_{1//2}$ (n ≥ 7), $4s^{2}$ np $\text{}^{2}P^{0}_{1//2}$ (n ≥ 5), $4s^{2}$ np $\text{}^{2}P$ $\text{}^{0}_{3//2}$ (n ≥ 6), $4s^{2}$ nd $\text{}^{2}D_{3//2}^{0}$ (n ≥ 6), $4s^{2}$ nd $\text{}^{2}D$ $\text{}_{5//2}^{0}$ (n ≥ 6) series in neutral gallium. The use of the quantum defect theory and Martin's expressions allowed us to supply lifetime values along by means of the series above. The results obtained in this work presented good agreement with theoretical and experimental values. Moreover, some lifetime values not existing in the literature for highly excited Rydberg states in gallium atom were obtained using this method.

Opis:
Nuclear medicine is great for viewing the roles of body organs. Medical imaging in nuclear medicine takes radioactive pharmaceuticals and studies their path of progress through patient's body. The principles of nuclear medicine are different from those of diagnostic radiology. The nuclear medicine can study the functioning of body and how it actually works. On the other hand, usage of different kinds of radiopharmaceuticals in nuclear medicine examinations can affect the dose rates. The purpose of our investigation was to estimate the effective dose from most common procedures, performed in nuclear medicine departments. We noted the injection radiation doses, which are used for diagnosis in nuclear medicine clinics. Later patient radiation doses were calculated, according to models recommended in ICRP 106.

Opis:
In this study, inhibitor effects of thymol and carvacrol were investigated in vivo and in vitro on acetylcholinesterase enzyme of Drosophila melanogaster. IC₅₀ values, Ki constants and inhibition types were determined for the substances displaying inhibitory effect. In vivo studies, were performed on larvaes by considering IC₅₀ values. The surviving and mortality rates were determined for the solution applied to larvaes. IC₅₀ values of thymol and carvacrol were found to be 25 mM and 0.175 mM, respectively. By using Lineweaver-Burk graphs, it was found that both compounds show non-competitive type of inhibition. According to results, it was concluded that carvacrol is a more effective inhibitor than thymol. We believe that these findings will contribute to the development of more potent, specific and effective inhibitors against AChE enzyme, design of new drugs for treating Alzheimer's disease and studies in pharmacological applications.

Opis:
The strength and elongation at break of a seam are very important characteristics of comfort clothing. Optimum seam strength must be durable enough to do our daily activities easily. Some parameters such as the type and count of the sewing yarn, the seam density, the size of the sewing needle, and type of stitch affecting the strength and elongation at break of the seam. In this study two kinds of fabrics (gabardine and poplin) were chosen for experiments. As sewing parameters, two different types of stitches (plain and chain stitch), five seam densities (3, 4, 5, 6 and 7 seams/cm), two kinds of sewing needles (SPI and SES), and three kinds of sewing yarns (cotton, core-spun, and PBT yarns) were used in experiments. With these materials 120 different seam variations were developed. Each sampless seam strength was tested according to the ISO 13935-1[1] standard using an Instron 4411 instrument. After the testing process, an artificial neural network model was developed to predict the seam strength and elongation at break values. The test results were applied to multi layer perceptron and radial basis function neural network modeling. These two neural network types were compared in terms of the accuracy of the modeling system. The results show that the artificial neural network model produces reliable estimates of seam strength and elongation at break (R=1, MSE=3.33E-05).
Wytrzymałość szwu i wydłużenie przy zerwaniu są bardzo ważnymi cechami ubrań z punktu widzenia wygody noszenia. Optymalna wytrzymałość szwu musi być wystarczająco duża, aby z łatwością wykonywać nasze codzienne czynności. Niektóre z parametrów, takich jak typ oraz numer przędzy, gęstość szwu, rozmiar igły do szycia, typ ściegu wpływają na wytrzymałość szwu i wydłużenie przy zerwaniu. Badania przeprowadzono na dwóch rodzajach tkanin (gabardyna i popelina), stosując dwa różne rodzaje szwów (proste i łańcuszkowy), szwy o pięciu gęstościach (3, 4, 5, 6 i 7 szwy/cm), dwa rodzaje igieł (SPI i SES) i trzy rodzaje przędz (bawełniana zwykła, rdzeniowa i przędze PBT), otrzymując 120 wariantów szwów. Wytrzymałość każdej próbki została zbadana zgodnie z normą ISO 13935-1 za pomocą przyrządu Instron 4411. Następnie, opracowano model sztucznej sieci neuronowej w celu przewidzenia wartości wytrzymałości szwów i wydłużenia przy zerwaniu. Wyniki badań zostały przetworzone w wielowarstwowym perceptronie i funkcji radialnej modelowania sieci neuronowej. Obydwa typy sieci neuronowych zostały porównane pod względem dokładności modelowania. stwierdzono, że za pomocą modelu sztucznych sieci neuronowych można uzyskać wiarygodne wyniki (R = 1, MSE = 3.33E-05).

In this work, both hardware and software of a palm vein capture system have been designed and a prototype is produced. By using this system, a genuine database was created with age and gender information of volunteered test subjects. Widely used pre-processing, acquisition of feature vectors, and classification methods were tested on the database and results are compared with speed versus accuracy. All the modules used in hardware and software were determined as open source. Python has been chosen as a software module programming on a single board computer with Linux kernel. As a result, an appropriately running system has been built with both secure software and hardware interfaces having maximum accuracy at 95.33% while specificity is at 100%.

In this study, the wear behaviors of curvilinear involute-profile gears, which were intended to be used in the industry and manufactured successfully, have been identified. For this purpose, the gears have been manufactured and attached to a FZG gear analysis bench; then, they were compared with spur gears by examining the behaviors of curvilinear involute-profile gears under different loads at different speeds, certain cycles. As a result of these analyses conducted, it has been determined that the wear behaviors of these newly manufactured curvilinear involute-profile gears are better than the behaviors of the spur gears, and in the increasing number of cycles, the curvilinear involute-profile gears had less wear than the spur gears have.

The present study aims to apply a least squares support vector model (LS–SVM) for predicting cleaning efficiency of an electromagnetic filtration process, also called quality factor, in order to remove corrosion particles (rust) of low concentrations from water media. For this purpose, three statistical parameters: correlation coefficient, root mean squared error and mean absolute percentage error were calculated for evaluating the performance of the LS–SVM model. It was found that the developed LS–SVM can be used to predict the effectiveness of electromagnetic filtration process.

Adsorption of Cu(II) and Ni(II) ions onto the waste powdered activated sludge biomass (PWB), which was obtained from the biological wastewater treatment plant, was investigated in this experimental study. The effects of contact time, pH, temperature, initial sorbate and sorbent concentrations on the adsorption were determined. The BET surface area, pore volume, and pore diameter of PWB were found to be about 0.51 m2/g, 0.0053 cm3/g, and 41.4 nm, respectively. Considering the R2  value, qexp  and qcal , the Langmuir and Freundlich models were well described for Cu(II) and Ni(II) adsorption, respectively. The adsorption mechanism of Cu(II) and Ni(II) onto the PWB could be better simulated by the pseudo-second-order kinetic mechanism than the pseudo-first-order, intra particle diffusion and Elovich models. Thermodynamic aspects of the adsorption of heavy metals were also investigated. Considering the applied desorbing agents for reuse of PWB for Ni(II) recovery, desorption cycle is not feasible due to the deterioration of the PWB structure.

Opis:
Soft/hard magnetic bilayers are attractive systems for investigating their physical behavior due to scientific curiosity and the potential for technological applications. Thus, 10 nm thick hard magnetic layer placed on a 20 nm soft magnetic layer was modeled in this work. After the constructing of magnetic thin films, the bilayer structure was simulated based on micro-magnetic modeling. When constructing the Hamiltonian of the system, magnetocrystalline anisotropy term was also under debate with classical Zeeman and exchange terms. Energy minimization in the simulation was performed using Metropolis algorithm and Markov Chain Monte Carlo (MC-MC) method. As a result of modeling, hysteresis curves, remanent magnetization and coercive fields were obtained at different temperatures.

Opis:
Natural resources have been decreasing with the large expansion of the world's population. In order to supply raw material for production, new recycling approaches should be developed for waste materials. Worn shoes is one of the most common waste products that can be recycled for this purpose. According to the record, shoes are very complex products, as they can be produced from forty different materials, like leather, rubber, polymers etc. Especially the bottom layers of the shoes are made from sound absorbing materials like polyurethane, thermoplastic rubber and PVC. Because today's technology is not able to separate these materials from each other during recycling, they should be used in a homogenised state. Thus these parts were shredded into small granules and mixed. PU binder and hot press were used to obtain samples for tests. In this paper sound absorption, sound isolation, vibration isolation and thermal insulation properties of the tread mixture are investigated. In addition to that, the mechanical properties of the material were also investigated by measuring the compression strength of the material.

We presented the results of electrical and optical studies of the properties of $In_xGa_{1-x}N$ epitaxial layers (0.060≤x≤0.105) grown by metalorganic vapour phase epitaxy. Resistivity and Hall effect measurements of the samples were carried out at room temperature. Optical properties of the samples were characterized by photoluminescence and optical absorption spectroscopy. The comparison between the photoluminescence and the optical absorption measurements gives the Stokes shift. We explained the observed Stokes shift in terms of Burstein-Moss effect. The band gap versus composition plot for $In_xGa_{1-x}N$ alloys is well fitted with a bowing parameter of≈3.6 eV.

Opis:
In this study, methyl jasmonate were applied to strawberry cultivars, and the pomological and biochemical characteristics of the fruits were investigated. The highest increase in fruit weight was determined in the Honeoye cultivar and it was detected in the application of 0.50 mM MeJa according to the control group. When the organic acid contents of fruits were examined, it was determined that the dominant acid was citric acid and the maximum range (Control: 1.49 g kg⁻¹; 0.50 mM MeJa: 16.49 g kg⁻¹) was in the Seascape cultivar. When the ellagic acid content of the fruits was examined, the highest increase (Control: 13.350 mg 100 g⁻¹, 0.25 mM MeJa: 22.768 mg 100 g⁻¹) was found in the Sweet Ann cultivar. In this study, it was determined that appropriate concentrations of MeJa should be preferred in cultivation of strawberry and these concentrations affected the fruit quality parameters.

Opis:
The aim of this study was to investigate the cardiotoxic effect of the combination of tilmicosin and diclofenac sodium in sheep. Thirty-two sheep were used and were randomly divided into four equal groups as tilmicosin (T), diclofenac sodium (D), tilmicosin+diclofenac sodium (TD) and control (C) group. Group T received a single dose of tilmicosin, Group D was administered diclofenac sodium once a day for 3 days, and group TD was administered diclofenac and tilmicosin at the same doses as group T and D. Group C received NaCl in a similar way. The blood samples were taken before dosing and at 4th, 8th, 24th and 72nd hour post-dosing for measurement of cardiac markers such as H-FABP, cTn-I, CK-MB. H-FABP level of group TD was found to be significantly (p<0.05) higher than of group C at the 8th, 24th and 72nd hour and group D and T at the 72nd hour. cTn-I and CK-MB levels of group TD were found significantly (p<0.05) higher compared with other groups. In conclusion, the combined use of tilmicosin and diclofenac in sheep causes an increase in cardiac biomarkers and it can be stated that this combination of drugs may cause cardiac damage.

Opis:
This research was conducted to address the experience of workplace violence of Turkish workers from different sectors and to investigate the impact of the exposed violence on their psychological well-being. Data were collected anonymously with printed questionnaires from the volunteer participants and depended on self-reporting. The response rate was 79.0% (1708/2161). The prevalence of workplace violence was found to be 44.8%. The most common type was verbal violence together with mobbing (bullying). Victims of physical violence were mostly males, whereas females were found to be victims of verbal, psychological and sexual violence. Most cases did not result in legal action and the victims remained silent. Psychological well-being of exposed workers in terms of depression, anxiety and stress seemed to deteriorate. Workplace violence remains a silent epidemic in Turkey. Preventive measures against workplace violence and social support for violated workers do not exist.
