The American National Standards Institute (ANSI) Class 150 is a system of dimensional standards for weld neck, threaded, slip-on, lap joint, socket weld and blind flanges. Dimensions for facing, bolts and studs are also included in ANSI Class 150. ANSI Class 150 establishes measures for pipe sizes.
The occipital lobes are the visual processing center of mammalian brains. The primary visual area is Brodmann area 17, located in the interior portion of the occipital lobe at the calcarine sulcus and sometimes continuing onto the surface of the lobe.The lobes' Peristriate regions are the sites for center visuospatial processing, for color discrimination and for discrimination of movement.he front edge of the occipital lobe is separated from the parietal lobe by the Parieto-occipital sulcus. The sides of the lobe merge with the parietal lobes along a vague boundary defined by several lateral occipital gyri, which are separated by lateral occipital sulcus.
The Frontal Lobe is located just behind the skull of the forehead, and it governs our ability to reason, make judgments, organize information and control some motor/muscle functions. The Parietal Lobe is near the back and top of the head.Itâs involved with visual attention, sensation (touch and pressure) and integration of senses. The Occipital Lobe is located at the back of the skull and controls vision. The Temporal Lobes are located on each side of the head above the ears.They control hearing and are related to smell, taste and short-term memory (especially visual and verbal).tâs involved with visual attention, sensation (touch and pressure) and integration of senses.
