Retrospective Evaluation and Comparison of All Medicolegal Autopsies Performed Before and After the COVID-19 Pandemic in İzmir

Objective:In this study, in the 2 year period before and after the first date of the COVID-19 case in Turkey (between 11.03.2019-10.03.2020-11.03.2020-10.03.2021) İzmir Forensic Medicine Group Presidency we aimed to show the effects of the SARS-CoV-2 pandemic by examining the autopsies and autopsy findings performed in the Izmir Forensic Medicine Group Presidency through the forensic autopsy records.Methods:Our study was planned as a retrospective study of autopsies performed in İzmir Forensic Medicine Group Presidency. The work will start after the necessary permissions are obtained from the İstanbul Forensic Medicine Institute. The data of autopsies performed between 11.03.2019-10.03.2020 and 11.03.2020-10.03.2021 in the İzmir Forensic Medicine Group Presidency will be analyzed in terms of age, gender, cause of death, origin of death and mode of death.Results:A total of 4604 autopsy cases were examined in our study. In the pre-pandemic period, the number of female cases was 472 (21.4%), the number of male cases was 1734 (78.6%), the most common form of death was suspicious death with 1192 (54%), and the most common origin was 1039 (47.1%) was detected as natural death. After the pandemic, these numbers were found to be 413 (17.2%) for women, 1985 (82.8%) for men, 1398 (58.3) suspicious deaths and 1072 (44.7%) natural deaths.Conclusion:As in all areas of life, changes have occurred in forensic autopsy practice with the COVID-19 pandemic, and we think it is important to share the data we have obtained as a result of examining and analyzing all forensic autopsies performed during and before the SARS-CoV-2 pandemic in Izmir for two years

Effect of H3BO3 on the Corrosion Properties of Ni-B Based Electroplating Coatings

In this study the effect of H3BO3 on the properties of Ni-B coating formed on the AISI 1020 steel surface produced with electroplating process was investigated. Synthesis of the coatings was done using acidic electro plating bath. Coating process was carried out within a standard cell with three electrode system using platinum as auxiliary and Ag/AgCl electrode as a reference electrode onto AISI 1020 steel substrate. Then, heat treatment was applied to coatings at 400 degrees C during a period of 1 h. The coated samples were analyzed by optical microscope, scanning electron microscope, and X-ray diffraction. Micro hardness measurements of the coatings were realized. The study reveals that the Ni-B anti corrosion coating is amorphous in their as-plated condition and upon heat treatment at 400 degrees C for 1 h, Ni-B coatings crystallize and produce nickel borides and nickel in the coatings. The results indicated the presence of Ni2B, Ni3B and Ni phases

Polycystic Ovary Syndrome and the Risk of Obstructive Sleep Apnea: A Meta-Analysis And Review of The Literature

Background and Objective Polycystic ovary syndrome (PCOS) has been reported to be associated with the development of obstructive sleep apnea (OSA). The objective of this meta-analysis is to assess the relationship between PCOS and OSA. Methods A literature search was conducted to identify studies linking PCOS with the risk of OSA. Studies in which the presence of OSA was confirmed with overnight polysomnography were included. Random effects models were used to calculate pooled relative risks. Results Eight studies conducted in adults and five studies conducted in adolescents were identified. The pooled OSA prevalence was 0.22 (95% confidence interval (CI): 0.08–0.40) in PCOS patients. The pooled prevalence of OSA was higher in adults (0.32, 95% CI: 0.13–0.55) than adolescents (0.08, 95% CI: 0.00–0.30). Risk of OSA was significantly increased in adult patients with PCOS (odds ratio (OR) 9.74, 95% CI: 2.76–34.41). Risk of OSA was not significantly increased in adolescents (OR: 4.54, 95% CI:0.56–36.43). Conclusions These findings demonstrate a significant association between PCOS and OSA in adult patients. Considering the increased risk for long-term cardiometabolic disorders associated with both PCOS and OSA, it is important to diagnose and treat OSA in patients with PCOS.PubMedWoSScopu

Assessment of the Fundamental Resonance Frequency of the Sedimentary Cover in the Eskisehir Basin (Turkey) Using Noise Measuremeets

Geological observations indicate that the Eskisehir graben is related with Eskisehir Fault Zone (EFZ), one of the major active structures within the Anatolian plate. The fault zone has a considerable seismic risk for the urban area of Eski¸sehir. Local site conditions substantially affect the characteristics of seismic waves and generally have a direct effect on the potential of the earthquake damage. Site effects are very complex factors. The importance of site response is well known, and few would question the assertion that the motion on soil is usually greater than on rock, when all other things were being held equal. In general, site response estimation can be obtained from instrumental recordings. The purpose of this study was to estimate if there would be a relationship between the structural geology in the Eskisehir Basin and the fundamental resonance frequency. Extensive ambient noise measurements were performed in the basin of Eskisehir from June 2010 to spring 2012. In this work, we conduct microtremor surveys to investigate the 3-D basin structure of Eskisehir Basin and determine the fundamental resonance frequency of the sedimentary cover in the Eskisehir Valley area. The measurements of single-station microtremor were carried out at 318 sites in the Eski¸sehir Basin. We use data recorded by a broadband seismometer and digitizer CMG-6TD, Guralp seismometer. Some of the measurement locations, the CMG-6TD sensor was located into 30 cm-deep holes in the ground to avoid strongly wind-generated, long-period noise. Finally, a map showing the fundamental resonance frequency distribution in the studied area was drawn using the results obtained from applying the HVSR technique. A fundamental resonance frequency map of the Eskisehir Basin was produced from main peak in the horizontal-to-vertical component (H/V) spectral rati

Electrical properties of nitrogen implanted GaSe single crystal

N-implantation to GaSe single crystals was carried out perpendicular to c-axis with ion beam of 6x10(15) ions/cm(2) dose having energy values 30 keV and 60 keV. Temperature dependent electrical conductivities and Hall mobilities of implanted samples were measured along the layer in the temperature range of 100-320 K. It was observed that N-implantation decreases the resistivity values down to 10(3) Omega-cm depending on the annealing temperature, from the room temperature resistivity values of as-grown samples lying in the range 10(6)-10(7)Omega-cm. The temperature dependent conductivities exhibits two regions (100-190 and 200-320 K) with the activation energies of 234-267 meV and 26-74 meV, for the annealing temperatures of 500 and 700 degreesC, respectively. The temperature dependence of Hall mobility for the sample annealed at 500 degreesC shows abrupt increase and decrease as the ambient temperature increases. The analysis of the mobility-temperature dependence in the studied temperature range showed that impurity scattering and lattice scattering mechanisms are effective at different temperature regions with high temperature exponent. Annealing of the samples at 700 degreesC shifted impurity scattering mechanism toward higher temperature regions. In order to obtain the information about the defect produced by N-implantation, the carrier density was analyzed by using single donor-single acceptor model. We found acceptor ionization energy as E-a = 450 meV, and acceptor and donor concentration as 1.3 x 10(13) and N-d = 3.5 x 10(10) cm(4), respectively
