...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...

...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...

The novel draws the female character of Hagar, a ninety year old female who recounts her past life as she awaits her doom to be unwillingly sent to the nursing home by her son. Her reflections on her past acquaint the reader of Hagar’s character. Her experiences in childhood, her interaction with her father, her past decisions in life, i.e. her marriage to Bram against the wishes of her parents, and then finally her marital life and birth of two sons, all throw light on Hagar’s character as a woman of pride, who...

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...

Figure 3.1: Reposition error in 60 and 30 angles in NLBP group Figure 3.2: Reposition error in 60 and 30 angles in LBP group As illustrated in figure 3.2 low back pain group participants tend to undershoot the target position in 60 angle, on the other hand, the NLBP group tends undershoot in the 30 angle compared with the LBP group (figure 3.1). The average mean errors for both angles... Chapter III Results In this chapter, the results of testing procedure shall be presented through graphs and tables that pertain to the numbered...

...angle of 24o. What is the length of the arc? What is the area of the sector? (Hint: first convert to radians) Radius, cm Angle, Angle in Radians, Length of an arc is given by Therefore, ≈ 2.09 cm (2d.p.) The length of the arc is about 2.09 cm. Area of a sector is given by ( in radians) Therefore, ≈ 5.25 cm2 (2d.p.) The area of the sector is about 5.24 cm2. (b) In the diagram below the line AB is a tangent to the circle of radius x. What is the radius of the circle? (Hint: find out the definition of a tangent) A tangent to a circle is a straight line that touches the circle at only...

...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,...

...angle of elevation. The data was tabulated, and graphs were drawn and analyzed to find the dependence of maximum height reached by a body in projectile on initial velocity and angle of elevation. Introduction and background According to the fundamental laws of physics, when a body if projected into the air, its trajectory motion in determined by the Earths pulls of gravity. Since the gravitational pull acts downwards (vertical... Maximum height of a projectile motion The essence of this experiment was to investigate for the maximum height that can be reached by a projectile motion. From the motion of the two balls projected horizontally, the balls are projected at the same initial velocity and same...

...angles, transition and color balance among many others. An up-close analysis of how these are manipulated to communicate is done below through reviews of a number of short films. The film new boy begins with a closer up shot of the young black boy. This is an establishing shot revealing just enough details to help create the mood in the movie. A close up shot reveals just enough details to develop an understanding of the immediate surrounding. From this shot... Movie review Films are mediums of communication. Producers of films employ a number of techniques besides the story line to aid in communicating the intended message. Among the most commonly manipulated techniques include camera shots, camera...

...angle. Theoretically... Electromagnetic Teacher               Electromagnetic There is a resulting line or linear graph after plotting the points that corresponded to the results when the current was varied. Thus, there exists a linear relationship after the current supply was altered. Using MS Excel, the line of best fit was drawn in order to serve as the basis for calculating the universal force during the time that the current was altered. Here is the formula: 2- The graph above indicates how much force resulted when the coil length was varied. The coil length was altered through a range between 20mm and 80mm. The resulting relationship was linear. MS Excel once more helped drew the line of best fit an...
