Evaluation of possible adverse events in connection with the inconvenient use of macrolides

The aim of my thesis work was to demonstrate the possible results of invonvenient use of antibiotics..Most patients were aware of the connection between antibiotic use and antibiotic resistance.We should realize,if there are wrong definitions about antibiotic resistance.It makes clearer the patient doctor / pharmacist discussions. These discussions are about inhibiting the growings of resistance and social assistance for convenient use of antibiotic drugs.In my opinion, we can solve all these complicated situations with giving up some luxuries for the better effectiveness of antibiotic drugs.BSc/BAgyógyszerészangolg

p-Si(100)/InGaN thin film structure and investigation of its physical properties: N-2 gas flow effect

International Congress on Semiconductor Materials and Devices (ICSMD) -- AUG 17-19, 2017 -- Selcuk Univ, Konya, TURKEYWOS: 000495858400011In this study, effect of N-2 gas flow rates on structural, optical and morphological properties of InGaN thin films grown by Radio Frequency Magnetron Sputtering (RFMS) method on p-Si (100) substrate have been investigated. X-ray diffraction (XRD) measurements confirmed that InGaN thin films have been successfully deposited and exhibited diffraction peak belong to (002) plane for each film. The surface roughness of InGaN thin films has been determined by using Atomic Force Microscopy (AFM) and the roughness value is about 13 nm with a maximum height of 36 nm and a maximum depth of 37 nm. The surface roughness value Rq\RMS value is 15 nm, which is almost consistent with the linear roughness value for 0 sccm. The energy band gap of the film was determined by using the optical reflectance spectra and the value of the band gap energy is found to be 2.01, 1.77 eV and 2.26 eV for 0 sccm, 1 sccm and 2 sccm N-2 gas flow rates, respectively.

Medical Technologies National Conference (TIPTEKNO) -- OCT 15-18, 2015 -- Bodrum, TURKEYWOS: 000380505200096Approaches performed based on computer supported systems within the medical field gain more popularity day by day. In such systems, Artificial Intelligence techniques are often used for several disease diagnostics. Diabetes is one of these diseases. In this study, a diabetes diagnosis system based on Support Vector Machines has been proposed. Along training of SVM, Vortex Optimization Algorithm was used for determining the sigma parameter of the Gauss (RBF) kernel function, and a classification process has been done over the diabetes data set related to Pima Indians

Cognitive Development Optimization Algorithm Based Support Vector Machines for Determining Diabetes

WOS: 000376690700008The definition, diagnosis and classification of Diabetes Mellitus and its complications are very important. First of all, the World Health Organization (WHO) and other societies, as well as scientists have done lots of studies regarding this subject. One of the most important research interests of this subject is the computer supported decision systems for diagnosing diabetes. In such systems, Artificial Intelligence techniques are often used for several disease diagnostics to streamline the diagnostic process in daily routine and avoid misdiagnosis. In this study, a diabetes diagnosis system, which is formed via both Support Vector Machines (SVM) and Cognitive Development Optimization Algorithm (CoDOA) has been proposed. Along the training of SVM, CoDOA was used for determining the sigma parameter of the Gauss (RBF) kernel function, and eventually, a classification process was made over the diabetes data set, which is related to Pima Indians. The proposed approach offers an alternative solution to the field of Artificial Intelligence-based diabetes diagnosis, and contributes to the related literature on diagnosis processes

Synthesis and characterization of p-GaSe thin films and the analyses of I-V and C-V measurements of p-GaSe/p-Si heterojunction under electron irradiation

gur, emre/0000-0002-3606-2751WOS: 000415686200011Gallium Selenide (GaSe) thin films were grown by the electrochemical deposition (ECD) technique on Indium tin oxide (ITO) and p-Si (100) substrates. The Electron paramagnetic resonance (EPR) spectrum of GaSe thin films' growth on ITO was recorded at room temperature. According to EPR results, the g value of an EPR signal obtained for GaSe deposited on ITO is 2.0012 +/- 0.0005. In/GaSe/p-Si heterojunction was irradiated with high-energy (6MeV) and low-dose (1.53x10(10)e(-)cm(-2)) electrons. The ideality factor of the In/GaSe/p-Si device was calculated as 1.24 and barrier height was determined as 0.82eV from I-V measurements before irradiation. Acceptor concentration, built-in potential and barrier height of the In/GaSe/p-Si device were also obtained as 0.72x10(14)cm(-3), 0.65eV and 0.97eV from C-V measurements, respectively. After irradiation, the ideality factor n and barrier height phi(b) values of the In/GaSe/p-Si device were calculated as 1.55 and 0.781eV, respectively. Acceptor concentration, the built-in potential and barrier height values of the In/GaSe/p-Si device have also shown a decrease after 6MeV electron irradiation. This change in heterojunction device parameters shows that current transport does not obey thermionic emission, and thus tunneling could be active due to the defects formed by irradiation at the In-GaSe interface

X-ray photoelectron spectroscopy (XPS) and gamma-ray shielding investigation of boro-silicate glasses contained alkali/alkaline modifier

In the present work, seven glass samples have been prepared utilizing melt-quenching method with composition of 40B₂O₃-10SiO₂-10Al₂O₃-30ZnO-10 (Li₂O/Na₂O/K₂O/MgO/CaO/SrO/BaO) all in mol%. Scanning electron microscope (SEM) and Energy-dispersive X-ray spectroscopy (EDX) have characterized for H3 (K₂O) and H7 (BaO), to examine the structural properties. X-ray Photoelectron Spectroscopy (XPS) has shown that the boron (B) element composition is highest after oxygen elements in all the glasses. It has been also observed that incorporation of potassium (K) and strontium (Sr) elements are maximum compared to the other doped elements into the glass. Further, the photon shielding for H1-H7 samples were also studied. We calculated the mass attenuation coefficients (μ/ρ) for the present samples at some energies between 0.015 and 10 MeV. The results revealed that H7 (BaO) sample owns the highest μ/ρ values followed by H6 (SrO) while H1 (Li₂O) has the lowest μ/ρ. Moreover, H7 and H6 samples have higher effective atomic number than the rest of glasses. H7 sample has excellent shielding properties when compared with the other glasses. We found that the composition of the sample affects the attenuation of the glasses and high attenuation can be achieved when we used heavy metal oxides (such as BaO)

Comparison of Current Free Flap Options for Intraoral Lining and Tongue Reconstruction

Free flaps have become the main alternative for intraoral reconstruction in current practice. However, controversy exists on pros and cons of different free flap options for this challenging area. Although there are various studies focusing on different free flap options, comparative studies are very few and there is not a single study comparing all 4 thin free flap options for intraoral reconstruction. Between 2018 and 2021, 30 patients underwent intraoral reconstruction. Four pliable and thin flaps, medial sural artery perforator flap, superficial circumflex iliac artery perforator flap, radial forearm free flap, and superthin anterolateral thigh flap were used for reconstructions and compared per functionality and patients' quality of life. One medial sural artery perforator flap and 1 superficial circumflex iliac artery perforator flap failed because of perfusion problems, and the remaining flaps survived. Harvest time and donor site closure were with significant difference (P<0.05) between groups. Quality of life results were similar except one of the disease-specific questions. In authors' opinion, anterolateral thigh flap is the best option in normal-weight individuals because of its reliability, pliability, and constant reliable vascular structure. Although other options may be considered in overweighted patients, thinly elevated anterolateral thigh flap still seems to be the most reliable option
