Manufacturers of GPS devices say that adding GLONASS made more satellites available to them, meaning positions can be fixed more quickly and accurately, especially in built-up areas where the view to some GPS satellites is obscured by buildings.LONASS is a global satellite navigation system, providing real time position and velocity determination for military and civilian users. The satellites are located in middle circular orbit at 19,100 kilometres (11,900 mi) altitude with a 64.8 degree inclination and a period of 11 hours and 15 minutes.
Glandular tissue is tissue that is designed to secrete something. It is one of the major forms of epithelial tissue, which is the tissue that lines and covers most of the body, from the skin to the inside of the stomach. There are several different kinds, differentiated by how they function.
In young women the breast is often extremely dense. Glandular tissue and cancer are dense (white) in a mammogram. Hence it is difficult to distinguish cancer from normal dense glandular tissue in young women. As women age, there is fatty infiltration of the breast associated with atrophy of glandular tissue.owever, as women age, there is a fatty infiltration of the breast, which appears dark on imaging, therefore making it easier to identify cancerous lesions. Mammogram abnormalities include masses, calcifications, asymmetry and architectural distortion.
