Background:Objectives:Methods: Identification of human remain requires a comparison between ante-mortem and post-mortem evidences, as such, the use of bones that are often easily recovered intact like the maxilla, becomes necessary although the skull and other bones may be badly disfigured. To determine the precision with which the maxillary sinus volumes identifies sex. 130 subjects (79 males and 51 females), between 20 - 80 years, with normal maxillary sinus CT anatomy, from head CT scans carried out at the Radiology Department of the Usmanu Danfodiyo University Teaching Hospital (UDUTH) Sokoto from 2008 to 2012 were involved in this study. The volume of each sinus was determined by the product of three linear measurements (craniocaudal (height), anteroposterior (dept) and transverse (width) diameters), using Neusoft Dual Slide Helical CT machine and the slice thickness. These measurements were performed on three-dimensional reconstructed images using V-works 3.0 program. The discriminant analysis showed that the accuracy with which the maxillary sinus volume could identify sex was 50.6% in males, and 60.8% in females. Computerized Tomography estimation of maxillary sinus volume may be of value to support sex determination in forensic anthropology.

The in situ experimentation technique in HVEM seems to be particularly suitable to clarify the processes involved in recrystallization. The material under investigation was unidirectionally cold-rolled titanium of commercial purity. The problem was approached in two different ways. The three-dimensional analysis of textures was used to describe the texture evolution during the primary recrystallization. Observations of bulk-annealed specimens or thin foils annealed in the microscope were also made in order to provide information concerning the mechanisms involved in the formation of new grains. In contrast to the already published work on titanium, this investigation takes into consideration different values of the cold-work ratio, the temperature and the annealing time.Two different models are commonly used to explain the recrystallization textures i.e. the selective grain growth model (Beck) or the oriented nucleation model (Burgers). The three-dimensional analysis of both the rolling and recrystallization textures was performed to identify the mechanismsl involved in the recrystallization of titanium.
