Skeletal age determination exercise was performed by Greulich-Pyle method in 402 normal children (219 males and 183 females) aged 8-18 years during 1993-94 at Chandka Medical College, Larkana. On the average, the males were 1 year and the females were 0.5 years retarded from 8-15 years and from 8-13 years respectively. This retardation during childhood might be due to malnutrition, ill health o...

The Serpent Mound structure is a deeply eroded ancient impact in south central Ohio, about 8.0 km across. The age of the structure is poorly constrained by the geology. It post-dates the Lower Mississippian (ca.330 Ma) Cuyahoga Formation and predates Illinoisian glacial deposits. We analyzed the directions of magnetization of 60 rock samples taken from borehole cores drilled within and in the v...

Dental cementum is a vital tissue which demonstrates continuous apposition throughout the life of the tooth. This study was conduct on 101 impacted and 106 erupted mandibular third molar teeth extracted from healthy patients, aged 18-30 years. The buccolingual ground sections were prepared. The distance between the edges of enamel and cementum were measured with micrometer attached with light m...

Age determination is an important tool in wildlife studies. Estimating the age of animals in the field using tooth wear criteria may be subject to error as a result of variations between individuals, habitats and populations. Data on age estimation of leopards and tooth wear characteristics are lacking. Nineteen leopards in Namibia were assessed for tooth eruption and wear. Between 1991 and 199...

As the age characters of the fin whale (Balaenoptera physalus L.), the following have been reported hitherto. They are body length, stage of growth, number of ovulation, white scars (Mackintosh & Wheeler, 1929), baleen plate (Ruud, 1940), christalline lens (Nishiwaki, 1950), and ear plug (Purves, 1955). Among them, laminations presented in core of the ear plug is considered as the best age char...

In this paper, we are presenting a new approach for gender & age determination based on image mining with C means clustering. Image Mining is an area which is used for pattern recognition & other application.

The effects of stellar rotation on the photometric derivation of atmospheric parameters, ages and masses of main sequence B7-A4 stars are evaluated.Monte-Carlo simulations, used to generate a sample in themass range 1-5 M with all necessary individual rotational parameters and fundamental quantities, and the corrections on the photometric indices proposed by Collins & Sonneborn (1977), provide ...

Age determination and feeding habits of the Japanese threadfin bream, Nemipterus japonicus, was carried out in the northern Oman Sea (Chabahar area), based on 212 specimens collected between September 2009 and May 2010. The minimum and maximum fork length and body weight were measured as 145, 258 mm and 55.31, 288.12 g. The relationship between Body Weight (BW) and Fork Length (FL) for all indi...

Background The first step in assessing thoracic lesions is chest X-ray, but the optional imaging procedure for the final diagnosis is controversial. We aimed to examine the diagnostic accuracy of imaging modalities in pediatric thoracic masses. <em...

PURPOSE Demirjian's dental maturity scores and curves have been widely used for human age determination. Several authors have reported considerable differences between the true and estimated age based on the Demirjian curves, which have been accounted for by ethnicity. The purpose of the current study was to assess the role of ethnicity-specific dental maturation curves in age estimation of Sau...
