Article Citation - WoS: 5Citation - Scopus: 5Structural and Electrical Characterizations of the as Grown and Annealed Au/Mοo3< Bandpass Filters(Wiley, 2019) Khanfar, Hazem K.; Qasrawi, Atef; Daraghmeh, Masa; Abusaa, MuayadIn this work, the structural, morphology, and electrical properties of two 500 nm thick molybdenum trioxide layers that are sandwiched with indium slab of thickness of 200 nm (MoO3/In/MoO3 [MIM]) to form a bandpass filter are investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDX), and impedance spectroscopy techniques, respectively. The MIM films which coated onto Au thin film substrates by the thermal evaporation technique under vacuum pressure of 10(-5) mbar was post annealed at 250 degrees C in air atmosphere. While the XRD analysis revealed polycrystalline hexagonal lattice structure of the Au/MLM samples, the SEM and EDS analysis displayed grains of sizes of 350 nm and stoichiometric structure of MoO3. Electrically, indium layer which caused n-type conduction with donor level of 299 meV, forced the material to exhibit negative capacitance (NC) effect at high frequencies (above 1.1 GHz). The impedance spectroscopy which was recorded in the frequency domain of 0.01 to 1.80 GHz, also revealed low pass and high pass filters characteristics in the low and high frequency domains, respectively. The annealing of the Au/MIM samples, decreased the crystallite and grain sizes and increased the microstrain, the defect density and the stacking faults. Small amount of excess oxygen and some indium deficiency are observed upon annealing. In addition, the annealing shifted the donor level closer to the bottom of the conduction band and inverted the NC effect from high to low frequency regions. The study indicates the applicability of the Au/MIM/C structures as microwave cavities and parasitic capacitance cancellers in electronic circuits.Article Does Dexmedetomidine Induce Bone Regeneration in Cranial Defects in Rabbits(Taylor & Francis Ltd, 2025) Erkan, Gozde Nur; Tekin, Umut; Boyacioglu, Ozge; Korkusuz, Petek; Orhan, Kaan; Kirman, Betul; Onder, Mustafa ErcumentDexmedetomidine has been shown to exert protective and curative effects on various tissues and organs in different pathological processes. This study aimed to investigate the effect of dexmedetomidine on the regeneration process after making holes in the parietal bones of rabbits. Twenty-four male Oryctolagus cuniculus rabbits were allocated to three groups, and an 8-mm circular parietal critical-sized bone defect was induced in each animal. Group_C (control) received saline; Group_LD (low dose) was given dexmedetomidine 2.75 mu g/kg; Group_HD (high dose), dexmedetomidine 5.5 mu g/kg; all were administered intraperitoneally for 7 days. After 8 weeks the bones were examined by micro-computed tomography (micro-CT) and histomorphometry. The results indicated that regeneration was improved in both the dexmedetomidine-treated groups. The lower dose increased the bone volume ratio (BV/TV) more than the higher dose. Trabecular thickness, connectivity value, and connectivity density were also higher in Group_LD than in Group_HD. Significant intramembranous ossification was observed in the dexmedetomidine-treated groups, and active osteoblasts were seen at the margins of new bone trabeculae. We conclude that dexmedetomidine, especially at the lower dosage, increases osteoblastic activity and regeneration quality.Article Citation - WoS: 10Citation - Scopus: 10The Role of Environmental Factors in the Investment Prioritization of Facilities Using Recycled Pvc(Hard, 2021) Bac, UgurThere are many types of solid wastes however, plastic wastes are among the ones which have several harmful effects on the environment. Plastic wastes have a long decomposition time in nature and the dangerous chemical compounds in them make them a threat for the environment along with other types of waste. Contamination caused by the plastic wastes attracts worldwide attention nowadays. As a member of thermoplastic polymers family, polyvinyl chloride (PVC) products are one of the most preferred type of plastic composition, which holds an important ratio in the total plastic waste amount. PVC wastes should either be disposed or recycled to minimize their harmful effects on the environment. The disposal approach is easy and cheap, but recycling alternative requires the investment on special facilities hence, a more expensive solution. However, disposal alternatives, such as landfilling and incineration, may also cause pollution due to high chlorine content of PVC; whereas, mechanical and chemical recycling options reduce many environmental problems. There is a clear tradeoff in the decision of handling PVC waste between the costs and environmental effects. The purpose of this study is to evaluate the factors considered during the investment decisions of PVC manufacturers to find out the importance of environmental factors by using a multi-criteria group decision making method.Article Citation - WoS: 10Citation - Scopus: 9The Randomized Controlled Study of Low-Level Laser Therapy, Kinesio-Taping and Manual Lymphatic Drainage in Patients With Stage Ii Breast Cancer-Related Lymphedema(Galenos Publ House, 2023) Yılmaz, Sedef Selçuk; Ayhan, Fikriye FigenObjective: To compare the effects of low-level laser therapy, kinesio-taping and manual lymphatic drainage (MLD) on the affected arm volume, quality of life, arm function, neuropathic pain and shoulder mobility in patients with stage II breast cancer-related lymphedema. Materials and Methods: Forty-five breast cancer patients with stage II lymphedema were included. The patients were randomized to three groups and treated with MLD, kinesio-taping or low-level laser therapy. After these different therapeutic modalities, all patients received multilayer compression bandaging, lymphedema remedial exercises, skin care, and a patient education program by the same lymphedema therapist. All treatments were applied 5-days a week for three weeks. The lymphedema compression garments were prescribed to all patients and follow-up visits were planned at the end of the treatment, and at four and 12 weeks. The efficacy of the treatments was evaluated by volumetric calculations based on circumferential measurements using the formula for a truncated cone, in addition to goniometric assessments for shoulder joint ROM, and questionnaires: Quick-disability of arm, shoulder and hand for arm disability; pain-detect for neuropathic pain; and quality of life for arm lymphedema (LYMQOL-arm). Results: The baseline patient and disease characteristics, and outcome measures were similar between groups. All treatment modalities were found to be effective in decreasing arm volume, and improving quality of life, upper extremity disability and neuropathic pain. The percentage of decreased arm volume or treatment success was better in kinesio-taping group than in the MLD group at the end of the treatment, and at four and 12 weeks after treatment (p = 0.009, p = 0.039, and p = 0.042, respectively). Conclusion: Kinesio-taping led to better results than MLD and was similarly effective compared with low-level laser in stage II breast cancer-related lymphedema at the twelfth week of follow-up. Kinesio-taping and low-level laser should be considered as alternative treatments in early-moderate stages of lymphedema. After these modalities, multi-layer compression and compression bandaging remain cornerstones of lymphedema treatment.Erratum Erratum: Correction: Cardiac Hypertrophy Caused by Hyperthyroidism in Rats: the Role of ATF-6 and Trpc1channels (Canadian Journal of Physiology and Pharmacology (2021) 99 11 Doi: 10.1139/Cjpp-2021-0260)(Canadian Science Publishing, 2024) Aykanat, N.E.B.; Şahin, E.; Kacar, S.; Bağcı, R.; Karakaya, Ş.; Burukoǧlu, D.B.; Şahintürk, V.In the originally published article, the grant number was listed incorrectly in the funding statement.

This result may facilitate the transformation of some of the available single-OTA RC oscillators employing floating capacitors into the desirable form of employing grounded capacitors. The result turns out to be an aid to a Boolean circuit synthesis method previously given by Tao and Fidler for the generation of single-OTA RC oscillators.Article Citation - Scopus: 11Application of Rfid in Aviation Industry: an Exploratory Review(Faculty of Transport and Traffic Engineering, 2010) Mishra,A.; Mishra,D.Recently, Radio Frequency Identification (RFID) has received considerable attention and is considered to be the next wave of information technology revolution.

Co-Cr, Ti and Type IV Au alloys were selected based on their physical and mechanical properties. The 3D finite element models of three different bar clasp retentive tip geometries prepared from Co-Cr, Ti and Type IV Au alloys were constructed using the finite element software package MSC. Marc. Analysis of a concentrated load of 5N applied to the removable partial denture approach arms in an occlusal direction was performed. Although stress distribution and localisation within bar clasps with different retentive tips were observed to be similar and were concentrated in the approach arm, stress intensities differed in all models.Article Citation - WoS: 47Citation - Scopus: 54Effects of Smartphone Overuse on Headache, Sleep and Quality of Life in Migraine Patients(Riyadh Armed Forces Hospital, 2019) Demir, Yasemin P.; Sumer, Mehmet M.Objectives: To investigate the effects of smartphone overuse on headache, sleep quality, daytime sleepiness and quality of life in migraine patients. Methods: This study is a single-center, cross sectional comparative study. This study was conducted between July and September 2017 in the Neurology Clinic of a private hospital. Migraine disability assessment MIDAS) questionnaire was used to evaluate the disability status, and Mobile Phone Problematic Use Scale (MPPUS) was used to evaluate smartphone use frequency. The Visual Analogue Scale (VAS), 24-h Migraine Quality of Life Questionnaire (24-h MQoLQ), Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used to evaluate the pain intensity, quality of life, sleep quality and daytime sleepiness, respectively. Results: The study included a total of 123 patients. There was a significant difference between the groups in terms of pain intensity; frequency and duration as well as VAS, PSQI, 24-h MQoLQ and ESS (p<0.05) scores. There was a negative correlation between MPPUS and PSQI (r=-0.367, p<0.05); a strong positive correlation between MPPUS and ESS (r=0.675, p<0.05) and a negative correlation between MPPUS and 24-h MQoLQ (r=-0.508, p<0.05). Conclusion: Smartphone use has been observed to increase headache duration and frequency in migraine patients. Its overuse in migraine patients is related to poor sleep quality and daytime sleepiness; furthermore, as the smartphone use increases, sleep quality decreases, daytime sleepiness increases and quality of life decreases.
