Age determination and growth rate of the northern Benguela saddine (Sardinops sagax)
… objective of this study was to determine sardine age by counting rings on otoliths and to analyse the length, age and growth through regression and Von Bertalanffy Growth models. Otoliths amounting to 826 pairs were collected from the annual sardine research survey of the Ministry of Fisheries and …

DNA Methylation Analysis for Tissue and Age Determination for Forensic Human Identification
… relevant information about donors, such as the age of the individual.</p> <p>In this study, methylation markers were investigated to determine tissue specific markers to differentiate sperm from blood, saliva, and vaginal epithelial cells, and age specific markers to estimate the age group of a …

Thermoluminescence in Carbonate Rocks and its Application to Stratigraphic correlation and Geologic Age Determination
… are in stratigraphic correlation and geologic age dating. Both short- and long-range correlations have been attempted. No figures pertaining to geologic age dating by this method have been published. </p><p>Results of investigations show that, while glow curve data may be of some value, many …

The use of permanent maxillary and mandibular canines in sex and age determination in a South African sample
… of teeth are often used to help estimate the age and sex of unknown individuals. The aim of the study was two-fold. Firstly, it was determined whether sexually dimorphic characteristics exist in the size of permanent canines of South Africans, and whether these differences are of sufficient …

The Central Stoneroller, Campostoma Anomalum, as an Indicator of Heavy Metal Contamination Using Otolith Age Determination and Growth Analysis
… determined by regressing standard length on age in days, was significantly lower than those collected from the reference site. In addition, a significantly higher incidence of gross fin anomalies was observed at three landfill sites compared to two reference sites. Observed anomalies included …

Racemization of Amino Acids in Teeth for the Determination of Age
… of remains in an effort to determine age is an area of forensics that has received considerable attention. Traditional methods in age determination such as morphology are often biased, antiquated, and frequently result in a large margin of error. Conversely, the emergence of new …

Chromospheric activity and lithium abundance in the NGC2516 and NGC3766 open clusters
… of late type stars in open clusters of different ages. The study of open cluster is very important for our understanding of stellar evolution and atmospheres, since all cluster members have almost the same age and chemical composition and this allows to infer their properties more easily than …

Characterizing early growth and reproduction of Blueline Tilefish (<i>Caulolatilus microps</i>) to inform stock assessments
… from the mid-2000s to 2010s have raised management interest. During the most recent stock assessment, age reading difficulties found in the past persisted, and preferred age-structured models were not used. Additionally, maturity was estimated from a meta-analysis of other species with …

Age and Growth Determination of the Black Bullhead From Soft Fin Rays
Introduction: Knowledge of the age of individuals comprising populations of fish is essential to the fishery biologist. From such information he is able to calculate the rate of growth, determine the age at which sexual maturity is attained and the longevity of the species. These calculations and …

Noble gases anomalies in terrestrial ores and meteorites
… it is calculated that prior to the nuclear age, the equilibrium ratio of ¹²⁹I/¹²⁷ was between 2.2 x 10⁻¹⁵ and 3.3 x 10⁻¹⁵. 6. Measurements of the ¹³⁰Xe, formed from the decay of ¹³⁰Te, and the tellurium content allow the age determination of hydrothermal deposits of tellurium by the …

Paleoenvironmental Reconstruction of the Late Cretaceous Eastern Gulf Coastal Plain in Georgia and Alabama
… Results of carbon stable isotope analysis for determination of paleosalinity show the method to be useful, but best used in conjunction with other methods, including paleoecological analysis. The study also explored the use of strontium isotopes for the determination of paleosalinity, as well …

A STUDY OF MEDITERRANEAN BLUEFIN TUNA (Thunnus thynnus L.) WITH REFERENCE TO STOCK IDENTIFICATION AND MANAGEMENT STRATEGIES
The management of bluefin tuna (Thunnus thynnus) in the north Atlantic has been based on the assumption that there are two separate stocks (an eastern Atlantic stock, including the Mediterranean Sea and a western Atlantic stock). This hypothesis has never been scientifically confirmed. This study …
