The fractal structure of a white cauliflower is investigated by using the box-counting method on its cross section. The capacity dimension of the cross section is 1.88 ± 0.02, independent of the direction. From the result, we predict that the capacity dimension of a cauliflower is about 2.8. The vertical cross section of a cauliflower is modeled into a self-similar set of a rectangular tree. We...

many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...

we have modified one of the most useful methods of protein separation; namely, two dimensional gel electrophoresis (2-de). this modified version of 2-de is not only simpler and easier but also faster than all the currently available methods. in this method, isoelectric focusing is carried out in the first dimension using a vertical sodium dodecyl sulfate polyacrylamide gel electrophoresis (sds-...

Submit Manuscript | http://medcraveonline.com to excessive occlusal wear [4]. Excessive wear of anterior dental elements is a fact of high influence on the smile’s esthetics and harmony [3-5]. As cases become more complex, aspects related to the patient’s occlusion re-establishment must be observed, including the recovery of the occlusal vertical dimension (OVD), which is defined as the vertica...

Some of the most perplexing problems that the restorative dentist is called upon to treat involve those of the Class II deep bite patient. Class II deep bites are usually hereditary or are problems associated with growth or habit. Others have developed during adult life as a result of posterior teeth being lost or worn own, with subsequent tooth drift. These patients usually display a significa...

Full mouth reconstruction is one of the most effective methods to restore severe worn teeth that have suffered reduced vertical dimension. Although the use of the overlay splint restoration for a trial period allowing the patient to adapt to an increased vertical dimension is the recognized method, the specific protocol from the transitional splint to the fixed reconstruction is yet to be estab...

This study investigated the effect of different microwave curing cycles on the changes in occlusal vertical dimension of complete dentures. Four test groups with 12 maxillary dentures each were evaluated. Groups 1, 2 and 3 were polymerized with different cycles by microwave radiation and Group 4 was the control and cured by water bath. The average pin opening for all groups was less than 0.5 mm...

A technique for obtaining maxillomandibular registration for complete denture patients is presented. The maxillary rim is formed with the use of conventional techniques. The mandibular rim is made from modeling plastic impression compound on a record base formed by the patient into the neutral zone. The mandibular rim then is reheated, and the patient determines the occlusal vertical dimension ...

Excessive occlusal wear can result in pulpal injury, occlusal disharmony, impaired function and aesthetic deformity. Loss of anterior guidance can result from severe wear of anterior teeth, which protects the posterior teeth during excursive movement. The collapse of posterior teeth also results in the loss of normal occlusal plane and the reduction of the vertical dimension. This clinical repo...

This paper investigates the algorithmic dimension spectra of lines in the Euclidean plane. Given any line L with slope a and vertical intercept b, the dimension spectrum sp(L) is the set of all effective Hausdorff dimensions of individual points on L. We draw on Kolmogorov complexity and geometrical arguments to show that if the effective Hausdorff dimension dim(a, b) is equal to the effective ...
