Role of mastoid process in determination of sex
Research Journal of Pharmacology and Pharmacodynamics, 2015The aim of this research is to evaluate mastoid process using human skull for determination of sex. The main purpose of this research is the ability to examine and determine the sex for unidentified using mastoid process. 50 male and 50 female undamaged skulls were examined. The parameters like mastoid process size and index were examined.

[Symposium of the Process of Fertilization — From Sex Determination to Epigenetics]
Zoological Science, 2005Two consecutive exocitotic events occur before and after gamete fusion being accomplished. Sea urchin sperm must undergo the acrosomal exocytosis that is triggered by fucose sulfate polymer in jelly coat in order to bind to the vitelline layer of the egg.

Determination of Sex from Mastoid Process By Discriminant Function Analysis
Journal of Anatomical Society of India, 2010Sex determination is vital for the identification of an individual. Often fragmentary remains are available for forensic identification making sex determination difficult. The mastoid region, a fragmentary piece of skull, is ideal for studying sexual dimorphism as it is resistant to damage due to its anatomical position at the base of skull.

Determination of Sex Using Mastoid Process
Indian Journal of Forensic Medicine and PathologyBackground: Anthropometric studies of bones play a crucial role in establishing identification, especially in fragmented skeletal remains. Mastoid process is acone shaped bony protuberance extending from mastoid region of temporal bone of the skull. It is usually undamaged, because of its unique and secured position.

Sex determination using the mastoid process using South Indian skulls
Research Journal of Pharmacy and Technology, 2016Sexual dimorphism plays an inevitable role in forensic science. Mastoid process shows evident difference between male and female skulls. This study aims to determine the sex of 50 dry South Indian skulls using mastoid process. Sexual dimorphism using skulls has been quite a task in forensic science. This study aims to contribute towards it.

International Journal of Science Education, 2006
The more science and mathematics subjects that pupils in pre-university education include in their final examination package, the more future academic routes are available to them. Equality of educational opportunity is thus threatened when groups of pupils, distinguished by sex and family background but otherwise of equal capacities and achievement ...

Sex determination using mastoid process measurement in Thais.
Journal of the Medical Association of Thailand = Chotmaihet thangphaet, 2012Analysis of skeleton is necessary for sex determination. There are several pieces of bone that are used such as pelvic bone and zygomatic arch etc. In the fieldwork of physical anthropologist and forensic physician, the skull or some pieces of the skull can be very useful.

Aquaculture, 2016
Abstract Gonadal sex differentiation in gonochoristic fish is generally labile and under the control of two interacting processes: genetic sex determination (GSD) and environmental sex determination (ESD). Numerous experimental studies deal with temperature induced-sex differentiation in teleosts, but none focused on the African catfish Clarias ...

The Pacific oyster Crassostrea gigas is a commercially important bivalve in aquaculture worldwide. C. gigas has a fascinating sexual reproduction system consisting of dioecism, sex change, and occasional hermaphroditism, while knowledge of the molecular mechanisms of sex determination and differentiation is still limited.
