Microvascular research is seriously hampered by the great temporal and spatial variability of the measured skin blood flow and variation in sympathetic vasomotor reflexes within and between persons. Therefore skin vasomotor reflexes were studied before and after ulnar nerve blockade within the same person, resulting in a temporal complete denervation of the fifth finger and partial denervation ...

Tactile sensitivity has been measured in 101 normal individuals (38 females and 63 males) of European origin, and compared with ridge pattern characteristics of the fourth fingertip of the right hand. There is a relationship of tactile sensitivity performance with the type of pattern, particularly in females, and also with the number of junctions within the pattern, particularly in males. The p...

The problem of the etiology of congenital heart disease has lately been attracting increasing attention. Most studies, to date, have dealt with family histories, and the results of these suggest that recessive inheritance may account for a significant number of cases. The demonstration of an association between individual types of congenital heart disease and somatic hereditary traits could be ...

The displacement of a more viscous fluid by a miscible, less viscous one of lower density in a horizontal capillary tube is studied by means of Stokes flow simulations. Both axisymmetric and three-dimensional simulations are conducted at Péclet numbers up to 104, in order to resolve discrepancies between earlier simulations by [C.Y. Chen, E. Meiburg, Miscible displacements in capillary tubes. P...

In this paper, a real time embedded finger vein recognition system for personal authentication and vehicle security is proposed. Vein patterns are different for each finger and for each persons and as they are hidden underneath the skin’s surface, forgery is extremely difficult these unique aspects of finger vein patterns recognitions set it apart from previous forms of biometrics and have led ...

Tactile learning transfers from trained to untrained fingers in a pattern that reflects overlap between the representations of fingers in the somatosensory system (e.g., neurons with multifinger receptive fields). While physical proximity on the body is known to determine the topography of somatosensory representations, tactile coactivation is also an established organizing principle of somatos...

Dip-pen nanolithography (DPN) has emerged as a general tool for fabricating nanopatterns on a range of substrates, including metallic, insulating and semiconducting substrates. In DPN, an atomic force microscope (AFM) tip functions as a source to continuously create nanodroplets of molecules that then spread to form a self-assembled monolayer (SAM) on a substrate. Molecular transport from the t...

Background Dermatoglyphics could assist in the diagnosis of congenital abnormalities. The aim of this study was to identify the dermatoglyphic patterns (finger print pattern type, total ridge count of each finger, a-b ridge count, and articulotrochanteric distance [ATD angles]) in the parents of cystic fibrosis children. Materials and Methods We recruited 75 parents of children with cystic fibr...

The finger print patterns (F.P.Ps.) were studied in 1120 healthy individuals of Bundelkhand region. It was found that the type of F.P.Ps. in one particular hand, is dependent upon the finger on which the pattern is manifested, and the specific print patter on the corresponding finger of the other hand. It is discussed that the phynotypical expression of F.P.P. is due to the interaction between ...

Recently, a new biometric technology based on human finger-vein patterns has attracted the attention of biometrics-based identification research community. Compared with other traditional biometric characteristics (such as face, iris, fingerprint, etc.), finger vein exhibits some excellent advantages in application. For instance, apart from uniqueness, universality, permanence and measurability...
