    Overtopping Failure of a Homogeneous Earth-Fill Dam With Two Different Breach Sizes and Rough Downstream Conditions
    (Crc Press-balkema, 2024) Taskaya, E.; Buyuker, Z.; Ozturk, B.; Bombar, G.; Tayfur, G.
    In this experimental study, sediment movement as a result of the failure of homogeneous earth-fill dams was investigated for rough downstream conditions compared with two different breach sizes. The dam body with 2.02 m width, 10 cm crest width, 60 cm height, and 32 degrees upstream and downstream slope was constructed with material with a median grain diameter of D-50 = 0.441 mm in a rectangular reinforced concrete channel with a width of 2 m. In the top middle of the dam body for the overtopping scenario, a 5 cm and 25 cm deep breach was triggered for experiments. The roughness downstream of the dam was created by placing 13 concrete cubes of 10x10x10 cm at regular intervals. The most obvious difference between the experimental results is that the sediment thickness propagated along the downstream is in the experiment where the depth of the breach is high.

    Investigation of the Effect of Using Geogrids on the Performance of the Road in Pavements Constructed With Reduced Layer Thicknesses
    (Crc Press-taylor & Francis Group, 2024) Terzi, S.; Saltan, M.; Gokova, S.; Erkmen, F.; Tutumluer, E.; Karasahin, M.; Yalcin, E.
    In this study, the structural performance of road pavements with reduced layer thicknesses at different rates using geogrids was examined, and the benefits of geogrids in preventing rutting were investigated. Within the scope of the study, a total of 16 test sections of 50 meters in length, 12 with geogrids and four without geogrids, were constructed on the Adana - Kozan road determined by the General Directorate of Highways of Turkey (KGM). The constructed sections were divided into two, and besides the reference sections, two types of geogrids with different geometric structures were used in successive sections. Some layer thicknesses used in the study were determined following the specification, and the other part was determined through a pavement design program. In addition, to compare the effect of using geogrids in different locations on the pavement performance in the application sections, the geogrid was used in two positions, on the subbase layer and between the base layer. Data from the load, displacement and temperature sensors placed between the layers during the construction phase and on-site Heavy Weight Deflectometer (HWD) data at certain time intervals were used to observe the structural performances of the constructed pavement sections. In addition, GPS and IRI measurements are made regularly. The traffic values of the trial section are also monitored. Examining the obtained data aims to compare the economic gain achieved by reducing the layer thicknesses, the cost to be spent for the geogrid, and to make cost-benefit analyses.

    Gangliosides as Therapeutic Targets for Neurodegenerative Diseases
    (Hindawi Ltd, 2024) Inci, Orhan Kerim; Basirli, Hande; Can, Melike; Yanbul, Selman; Seyrantepe, Volkan
    Gangliosides, sialic acid-containing glycosphingolipids, are abundant in cell membranes and primarily involved in controlling cell signaling and cell communication. The altered ganglioside pattern has been demonstrated in several neurodegenerative diseases, characterized during early-onset or infancy, emphasizing the significance of gangliosides in the brain. Enzymes required for the biosynthesis of gangliosides are linked to several devastating neurological disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), Huntington's disease (HD), amyotrophic lateral sclerosis (ALS), hereditary spastic paraplegia (HSP). In this review, we summarized not only the critical roles of biosynthetic enzymes and their inhibitors in ganglioside metabolism but also the efficacy of treatment strategies of ganglioside to address their significance in those diseases.

    Search for Resonances and Quantum Black Holes Using Dijet Mass Spectra in Proton-Proton Collisions at S =8tev
    (American Physical Society, 2015) Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A.; Adam, W.; Bergauer, T.; Dragicevic, M.; Hegeman, J.
    A search for resonances and quantum black holes is performed using the dijet mass spectra measured in proton-proton collisions at s=8TeV with the CMS detector at the LHC. The data set corresponds to an integrated luminosity of 19.7fb-1. In a search for narrow resonances that couple to quark-quark, quark-gluon, or gluon-gluon pairs, model-independent upper limits, at 95% confidence level, are obtained on the production cross section of resonances, with masses above 1.2 TeV. When interpreted in the context of specific models the limits exclude string resonances with masses below 5.0 TeV; excited quarks below 3.5 TeV; scalar diquarks below 4.7 TeV; W′ bosons below 1.9 TeV or between 2.0 and 2.2 TeV; Z′ bosons below 1.7 TeV; and Randall-Sundrum gravitons below 1.6 TeV. A separate search is conducted for narrow resonances that decay to final states including b quarks. The first exclusion limit is set for excited b quarks, with a lower mass limit between 1.2 and 1.6 TeV depending on their decay properties. Searches are also carried out for wide resonances, assuming for the first time width-to-mass ratios up to 30%, and for quantum black holes with a range of model parameters. The wide resonance search excludes axigluons and colorons with mass below 3.6 TeV, and color-octet scalars with mass below 2.5 TeV. Lower bounds between 5.0 and 6.3 TeV are set on the masses of quantum black holes. © 2015 CERN, for the CMS Collaboration.

    Search for Supersymmetry With Photons in Pp Collisions at S =8tev
    (American Physical Society, 2015) Khachatryan, V.; Sirunyan, A.M.; Tumasyan, A.; Adam, W.; Asilar, E.; Bergauer, T.; Calvo, E.
    Two searches for physics beyond the standard model in events containing photons are presented. The data sample used corresponds to an integrated luminosity of 19.7fb-1 of proton-proton collisions at s=8TeV, collected with the CMS experiment at the CERN LHC. The analyses pursue different inclusive search strategies. One analysis requires at least one photon, at least two jets, and a large amount of transverse momentum imbalance, while the other selects events with at least two photons and at least one jet, and uses the razor variables to search for signal events. The background expected from standard model processes is evaluated mainly from data. The results are interpreted in the context of general gauge-mediated supersymmetry, with the next-to-lightest supersymmetric particle either a bino- or wino-like neutralino, and within simplified model scenarios. Upper limits at the 95% confidence level are obtained for cross sections as functions of the masses of the intermediate supersymmetric particles. © 2015 CERN. © 2015 CERN, for the CMS Collaboration.
