compound action potential (cap) of spinal cord represents valuable properties of neural fibers including excitability, rate of myelination and membrane integrity. these properties are measured using amplitude, latency and area under curve of caps recorded from spinal cord. here, the isolated spinal cord was set in a double sucrose gap (dsg) chamber and its response to intracellular stimulation ...

One of the main issues involved during tunnel construction with tunnel boring machines is the tail gap grouting. This gap is between the external diameter of tunnel lining and the excavation boundary that is filled with high-pressure grouting materials. In this work, three different approaches of gap grouting modeling in the FLAC3D software are investigated with a special attention to the...

This model focuses on the behavior of capillary-tissue fluid exchange system when the diameter of the capillary is less than that of red cell. In vivo and in vitro observations indicate that the width of the gap between the red cell and the vessel wall is generally small compared to the radius of the capillary for a single file flow of red cell in narrow vessel, particularly if the vessel diame...

Gap-analysis is the process of structuring and comparing two different situations or states in order to determine the difference or “gap” that exists between them. Once the “gap” is understood – and possibly also the “distance” between the states measured or otherwise assessed – it may then be possible to identify the steps or processes required to bridge the gap. General Morphological Analysis...

objective: access to demand quality of digital library services at university of tehran from the perspective of users (faculty members, library experts and student) by the digiqual model. research methodology: as for the objective, this research is an applied research and its nature is survey –analytic. the statistical population of this research is the group of users who are member of the digi...

The quasi-one-dimensional systems exhibit some unusual phenomenon, such as the Peierls instability [1], the pseudogap phenomena [2] and the absence of a Fermi-Dirac distribution function line shape in the photoemission spectroscopy [3]. Ever since the discovery of materials with highly anisotropic properties, it has been recognized that fluctuations play an important role above the three-dimens...

abstract background: quality of care is of great importance in health services as these services have the important mission to preserve health, and to give care to the society. the present study aimed to investigate the quality of midwifery services from the viewpoint of the clients, under coverage of health care centers in isfahan, through servqual model. materials and methods: this descriptiv...

polythiophenes are of considerable interest as synthetic metals. the optical properties of polythiophenes can be easily affected by alkyl chain or other side groups to the thiophene ring. the effect of polymerization degree on the energy gap was studied in the case of polythiophene as a conjugated polymer at b3lyp/6-31+g(3d,3p) level of theory. up to n = 16 could be confident that this degree o...

introduction: the libqual model measures 3 dimensions on a scale of approximately 22 aspects of services. the purpose of the present research was to evaluate the quality of services provided by libraries of isfahan university of medical sciences using the libqual model. methods: in a descriptive research, 368 users of libraries of isfahan university of medical sciences participated. data was co...
