periodontal ligament is a thin layer of soft tissue that connects root of a tooth to the surrounding alveolar bone. these ligaments play an important role in initiating tooth movement when loads are applied to teeth with orthodontic appliances. the majority of such soft tissues exhibit as viscoelastic bodies or have a time-dependent behavior. due to the viscoelastic behavior of the periodontal ...

so far the static properties of hadrons have been introduced in various models. the static properties of hadrons (charge radius, magnetic moment, etc.) are useful for understanding the quark structure of hadron. in this work we have introduced the hypercentral constituent quark and isospin dependent potentials. here constituent quarks interact with each other via a potential in which we have ta...

today fingerprinting techniques are increasingly adopted as an alternative and more direct and reliable means of assembling sediment source information. one of the principal assumptions of sediment fingerprinting is that potential catchment sediment sources can be distinguished on the basis of their physical, geochemical and biological properties or fingerprint properties. however, while the so...

Voltammetric properties of electrodes made of multiple-walled carbon nanotubes (MWNTs) with different diameters were investigated by cyclic voltammetry. The results indicate that electrodes made of smaller MWNTs exhibit better voltammetric properties. In addition, electrodes made of mixed MWNTs with large diameter distribution possess the best voltammetric properties. The phenomenon can be expl...

Harmonic elastic constants of 3-11 bp duplex DNA fragments were evaluated using four 5 ns unrestrained molecular dynamics simulation trajectories of 17 bp duplexes with explicit inclusion of solvent and counterions. All simulations were carried out with the Cornell et al. force-field and particle mesh Ewald method for long-range electrostatic interactions. The elastic constants including anisot...

Classical conditioning of the nictitating membrane response in rabbits is a well defined model of cerebellar-dependent motor memory. This memory undergoes a period of consolidation after the training session, when it is sensitive to reversible inactivations of the cerebellar cortex, but not of the cerebellar nuclei, with the GABA(A) receptor agonist muscimol. Here, the temporal properties of th...

The processes that develop and maintain the intrinsic electrical properties of neurons are modeled by allowing the maximal strength of membrane conductances to be slowly varying functions of the intracellular calcium concentration. The resulting dynamic regulation of conductances allows model neurons to self-assemble their membrane currents and to react to and recover from external perturbation...

The skin fulfills one of its most important functions, that is protection from mechanical injuries, due to the mechanism of reversible deformation of the structure. Human skin is a complex living material but in biomechanical tests it reveals its homogeneous nature. Biomechanical skin parameters change with time. Results of thickness measurements, where the skin was subjected to pressure, revea...
