...Angle Glaucoma: Physiological, Psychological, and Social Challenges Open-Angle Glaucoma: Physiological, Psychological, and Social Challenges Introduction About three million people in the USA have glaucoma, an incurable disease, which leads to blindness (11). Eighty thousand Americans are blind, due to glaucoma (4). A sizable number of glaucoma sufferers do not even know they have it. Regular screenings for glaucoma used to be highly encouraged, until scientists began to question whether the benefits were worth the risks of the screening. Screening was found to irritate the eyes and increase the risk of cataracts. Subsequently, screening became far less common. Now, again, scientists... are...

...Angle versus Acute Close-Angle Glaucoma Chronic Open-Angle versus Acute Close-Angle Glaucoma There are various disorders that continue to affect human. One of such disorders is glaucoma. The disorder is said to occur in human due to damage to the optic nerve. The optic nerve is involved with sending of visual signals from the eye to the brain (American Optometric Association, 2014). Hence, damage to the nerve hinders the transmission of visual images to the brain and, therefore, one is unable to see. There are various forms of glaucoma. However, there are two common forms of glaucoma: chronic open-angle and acute close angle. The paper focuses on symptoms, assessment, and diagnosis... Chronic Open-Angle...

Introduction to Squaring the Circle and Trisecting an Angle
Greek Mathematicians were amazed by the complexity of three geometrical constructions - squaring the circle, doubling the cube and trisecting an angle. These problems have kept the interest of mathematicians alive through generations. The present article studies the problem of trisecting an angle and squaring the circle. There are reasonable differences between the these two problems as former has no definite record of chronological references... Running Head: Squaring the Circle and Trisecting an...

...angle and time. In order to identify the problems faced by students in matters involving measurement, it is necessary that we all understand what measurement is all about. As Kamil and Clark, (1997) explains, measurement is a number which indicates a comparison between the attributes of the object under measurement and the same attributes of a given unit of measure. Often students are poorly informed on the on the differences between square, linear, and cubic centimeters. In early years, students have been reported of having difficulties in understanding that length remains the same when an object is moved to a different location either vertically or horizontally, or that...

...angle of direction. The properties mentioned above represent reflection and refraction respectively.
Reflection is visible when the direction of light is obscured by an opaque substance. Although some light may be absorbed by the substance, most of it bounces off the substances and moves in the opposite direction. The laws of reflection explain that both the angle of reflection and incidence are equal (Stille 37). However, this depends on the nature of the surface that lights bounces off. A smooth surface will produce an equal angle of reflection as that of incidence. However, a rough surface will produce multiple rays reflected at...

...angle of the tail (Rae & pope 1985). The tail plane of the model is also attached onto a single pin whose location is in a series of holes across the longitudinal plane of the aircraft. The tail plane normally fixes the setting angle of the tail of the plane and the angle in return plays a major role in the magnitude of the drag, lift and moment incurred while the plane is in operation. The range of the movement... In the given model of the airplane, there is twin engine jet. The tail plane of the model is all moving without aseparator elevator and therefore the movement of the control column that is used by the pilot to control the movement of the plane can easily be controlled by altering the angle of ...

...angle of perception. The impressions created to the perceiver, conform to the perceived object as it really is or as it is assumed to be as opposed to the actual stimulus. It is perceptual constancy that enables perceivers, whether human or animals, to identify different objects under different conditions. Snow, for instance will appear white in the moonlight. It will also appear the same in sunlight, almost a million times brighter. Perception... Lecturer Number Perceptual or object constancy refers to the tendency for viewed objects to appear very similar in terms of shape, color, size or location in spite of having a wide range of differences in observational conditions such as distance, lighting,...
