Hidden heroes of wars in legends with teleportation motif
(Geleneksel Yayincilik, 2020)Legends are stories about real or imaginary persons, events and places. In these stories, there are usually extraordinary events, but they are convincing. Thanks to this characteristic of legends, some moral principles and ... -
Almost η-ricci and almost η-yamabe solitons with torse-forming potential vector field
(Natl Inquiry Services Centre Pty Ltd, 2020)We provide properties of almost eta-Ricci and almost eta-Yamabe solitons on submanifolds isometrically immersed into a Riemannian manifold ((M) over tilde, (g) over tilde) whose potential vector field is the tangential ... -
Thermal and kinetic properties of poly(vinylacetate)/modified MWCNT nanocomposites
(Taylor and Francis Inc, 2020)The aims of this study were to improve the low thermal stability of poly(vinylacetate) (PVAc) polymer by forming its nanocomposite products according to solvent casting method with multi-walled carbon nanotube (MWCNT) ... -
Carbonic anhydrase III is a new target of HIF1 alpha in prostate cancer model
(Elsevier, 2020)Carbonic Anhydrase III (CAIII) belongs to a member of the alpha Carbonic Anhydrase (CA) family. Although some CA members are strongly up-regulated by HIF1-alpha, it is not known about the transcriptional regulation of CAIII ... -
An aminopyridine bearing pillar[5]arene-based QCM sensor for chemical sensing applications: design, experimental characterization, data modeling, and prediction
(IEEE-Inst Electrical Electronics Engineers Inc, 2020)This study presented that deca pyridin-2-amine bearing Pillar[5]arene (P5-PA) was designed in an appropriate cavity, which acts a part significant role in host-guest interactions of the macrocyclic molecules. P5-PA monolayer ... -
Leptophobic Z ' bosons in the secluded UMSSM
(Amer Physical Soc, 2020)We perform a comprehensive analysis of the secluded supersymmetric U(1)' model, consistent with present experimental constraints. We find that, in this model, the additional Z' gauge boson can be leptophobic without resorting ... -
A quest of G-continuity in neutrosophic spaces
(Wiley, 2020)Continuity, in particular sequential continuity, is an important subject of investigation not only in topology but also in some other branches of mathematics. Connor and Grosse-Erdmann remodelled its definition for real ... -
Total film thickness controlled structural and related magnetic properties of sputtered Ni/Cu multilayer thin films
(Elsevier Sci Bv, 2019)In this study, the impact of total film thicknesses on the structural and magnetic properties of multilayers was investigated. The multilayer films were produced by a DC magnetron sputtering system by considering different ... -
