finger patterns and ridge-counts in a random sample of iranian muslims consisting of 100 males and 100 females are described. the most common finger patterns found were loops, having a frequency of 54.4% u.l., 3.4% r.l. in males and 51.2% u.l. and 4.8% r.l in females. the frequencies of arches and whorls in both sexes were 4% and 38.5% respectively. bimanual and sex differences were indistinct....

A low cross-polarization slot array antenna in the narrow wall of ridge waveguide is presented. A non-angled slot which is created in the narrow wall of the ridge waveguide is considered to be used as radiating resonant slot. The normalized resistance and normalized reactance curves are presented for design purposes. A six element slot array waveguide antenna with ridges on its narrow wall is t...

Anomalies persist in the foundations of ridge regression as set forth in Hoerl and Kennard (1970) and subsequently. Conventional ridge estimators and their properties do not follow on constraining lengths of solution vectors using LaGrange’s method, as claimed. Estimators so constrained have singular distributions; the proposed solutions are not necessarily minimizing; and heretofore undiscover...

The astronomical site parameters for the Magdalena Ridge Observatory (MRO) are being studied from numerous aspects including meteorological, environmental, seismic and sky quality (e.g. “seeing”, cloud cover). Results to date indicate that MRO is an excellent site for astronomical observing. Seeing measurements of less that 1 arc second in the optical are routinely obtained. Seismic conditions ...

Alveolar ridge bone resorption is a biologic phenomenon that occurs following tooth extraction and cannot be prevented. This paper reviews the vertical and horizontal ridge dimensional changes that are associated with tooth extraction. It also provides an overview of the advantages of ridge preservation as well as grafting materials. A Medline search among English language papers was performed ...

The Foundation hotspot–Pacific-Antarctic Ridge (PAR) system is the best documented case of a fast spreading ridge approaching a hotspot and interacting with it. The morphology, crustal structure inferred from gravity anomalies and the chemical composition of the lavas of the axial area of the PAR show evidence of the influence of the hotspot, that is presently located roughly 35 km west of the ...

INTRODUCTION Vertical augmentation of the alveolar ridge is necessary for extensive resorption of the alveolar ridge. AIM To evaluate treatment outcome after alveolar ridge augmentation by a sandwich osteotomy combined with an interpositional allograft. PATIENTS AND METHODS The deficient alveolar ridges were augmented by a sandwich osteotomy combined with bovine collagen matrix as an interp...
