We have examined TeV scale effects of extra spatial dimensions through the processes q ! q, whereThese processes have been treated in a photon-proton collision via the main reaction pp ! pp ! pqX at the LHC. We have employed the equivalent photon approximation for incoming photon beams and performed statistical analysis for various forward detector acceptances.

We have investigated real graviton emission in the ADD and RS model of extra dimensions through the photoproduction process pp → pγp → pGqX at the LHC. We have considered all con- The constraints on RS model parameters have been calculated by considering G → γγ, eē, µμ decay channels of the graviton.

The measurements of the top quark flavor changing neutral current interactions are one of the most important goals of the top quark physics program in the present and the future collider experiments. These measurements provide direct information on non-standard interactions of the top quark. Within the framework of new physics beyond the Standard Model, these interactions can be defined by an effective Lagrangian. In this study, we have investigated the potential of the future µp colliders on the top quark flavor changing neutral current interactions through the subprocesses γq → t → W b where q = u, c. These subprocesses have been produced through the main reaction µp → µγp → µW bX at the LHC−µp, the FCC−µp and the SPPC-µp . For the main reaction, the total cross sections have been calculated as a function of the anomalous tqγcouplings. In addition, sensivities on BR(t → qγ) at 95% Confidence Level have been calculated.We obtain that the best constraints on BR(t → qγ) are at the order of 10 −7 which is four orders of magnitude better than the LHC's experimental results.

Determination of some seed characteristics provides important distinctive taxonomic data for species identification. In this study, seed characteristics such as measurements, weights and surface morphology of some unstudied taxa belonging to Fabaceae, Polygonaceae, Primulaceae, Violaceae, Rosaceae and Phyllanthaceae families native in Turkey, were investigated. Length and width of the seeds were measured with digital calliper using stereo-microscope. Seed weights were measured with Dikomsan precision scale. In addition to stereo microscope data, the surface ornamentation of the seeds was identified using scanning electron microscope. Accordingly, the smallest seeds were determined in Anagallis foemina (0.74 mm long and 1.11 mm wide) from Primulaceae family, while the largest seeds were determined in Rosa boissieri (4.95 mm long and 2.99 mm wide) from Rosaceae family. The heaviest seeds were measured in Rosa boissieri (0.0095 g) from the Rosaceae family and the slightest seeds in Anagallis foemina (0.0002 g) from the Primulaceae family. Mainly six types of the ornamentation were observed in SEM study of the species. The most common one was the reticulate ornamentation.
