1A fast and efficient coordinated vehicle-to-grid discharging control scheme for peak shaving in power distribution system显示文摘This study focuses on the potential role of plugin electric vehicles(PEVs) as a distributed energy storage unit to provide peak demand minimization in power distribution systems. Vehicle-to-grid(V2 G) power and currently available information transfer technology enables utility companies to use this stored energy. The V2 G process is first formulated as an optimal control problem.Then, a two-stage V2 G discharging control scheme is proposed. In the first stage, a desired level for peak shaving and duration for V2 G service are determined off-line based on forecasted loading profile and PEV mobility model. In the second stage, the discharging rates of PEVs are dynamically adjusted in real time by considering the actual grid load and the characteristics of PEVs connected to the grid. The optimal and proposed V2 G algorithms are tested using a real residential distribution transformer and PEV mobility data collected from field with different battery and charger ratings for heuristic user case scenarios. The peak shaving performance is assessed in terms of peak shaving index and peak load reduction. Proposed solution is shown to be competitive with the optimal solution while avoiding high computational loads. The impact of the V2 G management strategy on the system loading at night is also analyzed by implementing an off-line charging scheduling algorithm.Nuh ERDOGAN Fatih ERDEN Mithat KISACIKOGLU 2018Journal of Modern Power Systems and Clean Energy2018,6,3:12
2Comparison of one and three initial monthly intravitreal ranibizumab injection in patients with macular edema secondary to branch retinal vein occlusion显示文摘AIM: To compare three initial monthly intravitreal ranibizumab(IVR) injections followed by pro re nata(PRN) dosing with one initial monthly IVR injections followed by PRN dosing for macular edema(ME) secondary to branch retinal vein occlusion(BRVO).METHODS: Forty-two eyes of 42 patients who had IVR injections for BRVO were retrospectively studied. Eighteen eyes received 1 initial IVR injection(1+PRN group) and 24 eyes received 3 monthly IVR injections(3+PRN). At 1, 3, 6 and 12mo; spectral-domain optical coherence tomography(SD-OCT) was performed. Central macular thickness(CMT), the integrity of the external limiting membrane(ELM), the presence of subretinal fluid, cyst size, the presence of inner segment/outer segment(IS/OS) defect were determined.RESULTS: At baseline the mean CMT was 521.3±153.2 μm in the 3+PRN group while it was 438.1±162.4 μm in 1+PRN group. At the final visit, mean CMT was 278.3±87.8 μm in the 3+PRN group and 285.2±74.2 μm in the 1+PRN group(P=0.079). The changes in CMT over the entire study period were also comparable in both groups(243±160 μm in the 3+PRN group, and 152.9±175.3 μm in the 1+PRN group; P=0.090). At baseline, best-corrected visual acuity(BCVA) was 0.92±0.60 logarithm of the minimal angle of resolution(logMAR) in the 3+PRN group, while it was 0.72±0.46 logMAR in the 1+PRN group. Final BCVA was 0.42±0.55 logMAR in the 3+PRN group and 0.38±0.50 logMAR in the 1+PRN group(P=0.979). Additionally, the BCVA changes from baseline to final visit were not significantly different(-0.50±0.45 logMAR in the 3+PRN group, and-0.33±0.39 logMAR in the 1+PRN group; P=0.255).CONCLUSION: No significant differences in the anatomical or functional results are found between 3+PRN and 1+PRN regimens in the patients receiving ranibizumab for ME secondary to BRVO. Intact IS/OS and baseline BCVA are good predictor of the visual gain, while baseline CMT is a good predictor of the anatomical gain.Alper Halil Bayat Akin Cakir Seyma Gülcenur Ozturan Selim Bolükbasi Burak Erden Mustafa Nuri Elcioglu 2018International Journal of Ophthalmology(English edition)2018,11,9:6
3Seismic Tomography and Surface Wave Analysis Based Methodologies on Evaluation of Geotechnical Properties of Volcanic Rocks: A Case Study显示文摘Economic development, industrialization and dense population in Trabzon City have caused residential construction to increase by 300% in the last decade. The settlement area is mountainous and covered with heavy vegetation. Thus, the steep-sided topography and heavy precipitation means floods and landslides are common and in areas with little flat land. Since the mass movements in some parts of city create an enormous danger for buildings, site selection for residential areas becomes increasingly important. This paper describes geotechnical and seismic properties of Tertiary volcanic rock and establishes the link between these units and construction. In this study, refraction tomography and multichannel analysis surface wave methods were applied in order to seek the best construction site in the residential area. The results of the geophysical study were compared with the borehole applications. A series of geomechnical tests were carried out on the core samples. Following that, statistical correlations were conducted by regression analysis to evaluate relationships between measured parameters. Rock Quality Designation and weathering degree were also determined. The methodology defined in this investigation proves to be an appropriate approach to determine geotechnical properties of the foundation rocks and soils and a proper guide on future geotechnical studies for other cities.Ali Erden Babacan Kenan Gelisli Hakan Ersoy 2014Journal of Earth Science2014,25,2:4
4Clinical and impression cytology findings of amniotic membrane and oral mucosal membrane transplantation for the management of socket contracture显示文摘AIM:To investigate and compare the cytopathological and clinical effects of amniotic membrane transplantation(AMT)and oral mucosal membrane transplantation(OMMT)in socket contraction.METHODS:Twelve patients who could not be fitted with ocular prosthesis due to socket contracture were included in this study.Seven patients underwent AMT and 5 patients underwent OMMT.Thirteen patients who had healthy sockets were included as control group.Depth of inferior fornix,degree of inflammation,extent of the socket contracture and socket volume were measured in the preoperative period and at sixth and twelfth weeks postoperatively.Impression cytology of conjunctival fornices and tear transforming growth factor beta-1(TGFβ1)levels were determined.RESULTS:In the AMT group,socket volume and lower fornix depth values were significantly higher(P=0.030and P=0.004 respectively)and inflammation levels and impression cytology stages(P=0.037 and P=0.022respectively)were significantly lower in postoperative period compared to preoperative period.In the OMMT group,no statistical differences were found in terms of clinical parameters,inflammation levels and impression cytology stages of preoperative versus postoperative values.Preoperative tear TGFβ1 levels were higher in AMT and OMMT groups compared to the control group(25.5 ng/mL,26.3 ng/mL and 21.7 ng/mL respectively).Decreased tear TGFβ1 levels were observed in both the AMT and OMMT groups postoperatively(median decrease value=2.1 ng/mL and 2.7 ng/mL respectively).CONCLUSION:AMT is associated with postoperative improvement in inferior fornix depth,socket volume,inflammation and impression cytology levels and may bea more proper alternative method than OMMT in the management of socket contracture.Bengi Ece Kurtul Ugur Erdener Mehmet Cem Mocan Murat Irkec Mehmet Orhan 2014International Journal of Ophthalmology(English edition)2014,7,2:3

6Application of scoring systems with point-of-care ultrasonography for bedside diagnosis of appendicitis显示文摘BACKGROUND: Appendicitis is a common disease requiring surgery. Bedside ultrasound(BUS) is a core technique for emergency medicine(EM). The Alvarado score is a well-studied diagnostic tool for appendicitis. This study aimed to investigate the relationship between patients' symptoms, Alvarado score and ultrasound(US) findings, as performed by emergency physicians(EPs) and radiologists, of patients with suspected appendicitis.METHODS: Three EM specialists underwent the BUS course and core course for appendicitis assessment. Patients suspected of having appendicitis were selected and their Alvarado and modif ied(m) Alvarado scores calculated. The specialists performed the BUS. Then, patients were given a formal US and surgery consultation if necessary. Preliminary diagnoses, admission or discharge from the emergency department(ED) and fi nal diagnosis were documented. The patients were also followed up after discharge from the hospital.RESULTS: The determined cut-off value was 2 for Alvarado and 3 for m Alvarado scores. The sensitivities of the two scores were 100%. Each score was used to rule out appendicitis. The results of EP-performed BUS were as follows: accuracy 70%, sensitivity 0.733, specifi city 0.673, + LR 2.24, and – LR 0.40(95%CI). Radiologists were better than EPs at diagnosing appendicitis and radiologists and EPs were equally strong at ruling out appendicitis by US. When US was combined with Alvarado and m Alvarado scores, EP US+Alvarado/m Alvarado scores ≤3 and radiology US+Alvarado/m Alvarado scores ≤4 perfectly ruled out appendicitis.CONCLUSION: BUS performed by EPs is moderately useful in detecting appendicitis. Combined with scoring systems, BUS may be a perfect tool for ruling out decisions in EDs.Erden Erol Unluer Rifat Urnal Utku Eser Serkan Bilgin Mehmet Haciyanh Orhan Oyar Haldun Akoglu Arif Karagoz 2016World Journal of Emergency Medicine2016,7,2:2
7Lacrimal gland tumors in Turkey:types,frequency,and outcomes显示文摘AIM: To evaluate the clinical, radiological, and treatment features of lacrimal gland tumors.METHODS: Retrospective review of 99 eyes of 92 patients with lacrimal gland tumors diagnosed and managed in a single institution between January 1999 and March 2017. Clinical and radiological features, histopathology, treatment methods, and prognosis were evaluated.RESULTS: The mean patient age was 40.3(range: 7-80)y.The diagnosis was made histopathologically in 91(91.9%) tumors and on a clinical and radiological basis in 8(8.1%) tumors. Final diagnoses included idiopathic orbital inflammation(pseudotumor) in 46(46.5%) lesions, pleomorphic adenoma in 14(14.1%), adenoid cystic carcinoma in 12(12.1%), granulomatous inflammation in 10(10.1%), lymphoma in 5(5.0%), benign reactive lymphoid hyperplasia in 3(3.0%), dacryops in 3(3.0%), carcinoma ex pleomorphic adenoma in 2(2.0%), adenocarcinoma in 1(1.0%), dermoid cyst in 1(1.0%), cavernous hemangioma in 1(1.0%), and leukemic infiltration in 1(1.0%). Nonepithelial tumors comprised 64.6%(n=64) of all lacrimal gland tumors, epithelial tumors 32.3%(n=32), dermoid cyst 1%(n=1), cavernous hemangioma 1%(n=1), and leukemic infiltration 1%(n=1). There were in total 78(78.8%) benign and 21(21.2%) malignant tumors. CONCLUSION: Overall, 65% of lacrimal gland tumors were of non-epithelial origin and 32% of epithelial origin. By histopathology and clinical evaluation, 79% of lacrimal gland tumors were benign. The most common lacrimal gland tumors include idiopathic orbital inflammation(46.5%), epithelial(32.3%), and lymphoproliferative(8.1%) lesions.Yagmur Seda Yesiltas Ahmet Kaan Gundiiz Esra Erden Carol L.
