Essays on Lenses

Henry Fox was among the pioneers who inspired the art of photography just five years after its invention. By then, people were only used to drawings and thus photography was a completely new phenomenon. He published his first book which was mass produced for the audiences depicting how fast the art gained populace. The photographers by then struggled to convince the population that was used to painting as a form of art accept photographs as another form of art. The population valued the level of creativity in the drawings and the uniqueness of the themes therein represented. In the ...

Although the times of oppression related to gender, class, and race seem to have gone by, the issues of discrimination still matter in our country even nowadays when people finally seem to understand that diversity should be celebrated. According to Andersen and Collins, attitudes toward gender, class, and race are the foundation of our society and it is impossible to understand its structure, nor organization without taking into account this triad (Andersen & Collins, 2). This paper focuses on three issues related to how the subject should be dealt with in the modern context: intersection, or overlapping of different ingredients ...

Abstract

A sandstorm is characterized as one that whips up extraordinary loads of sand into the air, forming a dense cloud above the ground in the process. While most of the sand will rise higher than 50 cm, some sand particles can even ascend to the height of 2 meters. According to Wikipedia, the average diameter of the particles carried by such dust storm winds will vary between 0.15 and 0.30 mm. Wind speeds such during sandstorms have been recorded at up to 16 km per hour and more, while most storms continue to blow for between three hours to ...

At times, one can see many animals out in the night with their eyes glowing green or yellow-green in color. In all kinds of light and media such as nature films, photographs, flashlights and even car headlights, the greenish glow in the eyes of many animals is clearly visible. Human eyes, on the other hand, give off a red glow when exposed to the flash of a camera. The greenish glow in the eyes of many animals such as cats, dogs, deer, cattle and horses is mainly because of a special kind of reflective surface that lies behind the ...

Introduction

In spite of the unstoppable growth of technology, the hardware market remains one of the most competitive segments of the economy. While the demand is remaining relatively stable, the number of suppliers is dramatically increasing, especially in the light of the fact that large USA-based manufacturers started to open numerous development centers in the third-world countries, where qualified, but cheap labor is available. Furthermore, the practice demonstrates that more local hardware developers emerge on the business landscapes of those countries, making the competition climate for the companies from the USA more intense. Rachel, a Quality Assurance Engineer of a ...

Two Arguments on Homophobia

Introduction The discrimination of individuals who identify as homosexual or are thought to be gay is a common occurrence across the globe. Cities, boroughs and states have passed legislation that outlaws homosexuality. Negative attitudes towards homosexual people usually lead to hostility that come in verbal and physical attacks which sometimes result in death. Homophobia or the fear of individuals who are gay has been associated with religious and cultural beliefs, general ignorance about sexuality and the need to make homosexuality a tool for political gain. Using the case of Uganda’s Anti-Homosexuality Bill, this paper explores the causes of ...

The definition of the Western Canon is always changing, according to literary critic and Yale professor Harold Bloom: but is that mutability a good thing? Bloom, a rather conservative literary critic, believes that there should be literary standards that outlive the fashionable theories of the day. In our times, these literary theories include ideas borrow from Marx, Foucault, New Historicism, and ethnocentric and gender perspectives, among other lenses through which to view the production of literature. Amidst these ever-changing standards and definitions of a “classic,” Bloom believes the study of literature and good reading habits—to read well and ...

Solar Power Generation

Sustainable Technology – Solar Power Generation Power Generation from Fossil Fuels and Global Warming Global warming, as defined by Lineman, Do, Kim and Joo (2015), is the long-term trend of increasing average temperature of the lower atmosphere. It is widely known that this phenomenon is related to the concentration of greenhouse gases that trap heat in the atmosphere, such as carbon dioxide, methane, nitrous oxide, among others. Activities related to human development such as industrial processes, agriculture, cattle raising for meat consumption, transportation, deforestation and power generation are the major causes of greenhouse gases emissions. Specifically, power generation based on ...

When comparing two different types of digital video cameras, it really depends on what the needs are for the consumer. One camera I looked at is the Sony HDRCX900. It retails on Amazon for $1,298.00 and has a 3.5 inch LCD screen. It is a 2015 version, weighs a little over 3 pounds, has a remote commander, flash memory, and 12x optical zoom. The video input is 1080p. It is considered to be a professional compact digital video recorder with HD video. It also has built in Wifi capability (Amazon, n.d.) In comparison, a professional video camera is ...

A lens is an optical device used to alter the path of light in various optical applications. Lenses alter the path of light through refraction, which is phenomenon whereby the path of a ray of right shifts when it through materials with different density levels. Lenses are made from transparent materials, such as plastic or glass, which have been molded to give the required shape. A lens can be termed as either simple lens made from a single material, or a compound lens, which consists of an assembly of multiple lenses aligned along a common axis. Lenses are used ...

Literature review

Section 1: Background Context and rationale for research priorities Lens handling intensifies the incidence of lens contamination. When lens are aseptically removed from the eye, they still have a high probability of harboring microorganisms. During storage, the frequency of positive microbial bioburden remains high than 50%. The presence or movement of microorganisms from the lens to the ocular surface is a route factor for contact lenses related microbial keratitis and inflammation. There is need to priotise research in this area because the results of the studies help people to understand the factors concomitant to infectious and inflammatory complications. When ...

One is welcomed with a smile and warmth that makes one feel that every need in terms of the eye check up will be addressed. Initially, prior to seeing the doctor, there is a preliminary or a pre-testing that is done to provide valuable information such as the condition of the eyes of the patient, which will enhance the optician’s ability to assess the problem with the patient. Once an individual is seated, the initial thing that is done is to ensure that the patient is seated comfortably. In case there is no queue in the pretesting equipment, ...

Infrared Cameras

Introduction An infrared camera is a non-contact device that detects infrared energy and converts it into a visible light display. The infrared energy is first translated into electrical impulses that are then converted into data for camera display. The image or video formed on the screen is of different colors depending on the intensity of the infrared emission. Most cameras have built-in visible light digital cameras that allow merging of infrared and visual images. There are two different types of infrared cameras; cooled cameras and uncooled cameras. The cooled infrared cameras produce superior image qualities than uncooled cameras but ...

Introduction:

Transmission electron microscope (TEM) is the type of a microscope that uses a beam of electron rather than visible light to illuminate the specimen. Besides, while light microscope uses glass lens to focus light to the specimen, TEM uses electromagnetic lenses for focusing of the electron beam. TEM has a higher resolving power than the light microscope because the electron beam it uses for illumination has a much lower wavelength than visible light. During the operation of TEM, some electrons passing through the specimen get scattered and disappear from the beam. However, the unscattered electrons reach a fluorescence screen ...

Abstract

When Invisible Man, the seminal novel by Ralph Ellison was published in 1953, it quickly established a reputation as one of the most important literary depictions of the struggles of African-Americans in the history of fiction. The central character, the titular ‘invisible man,’ struggles with a metaphorical invisibility that was endemic to the 20th-century attitudes of white hegemony toward African-Americans, and encapsulated the black experience as one of marginalization and oppression. These elements contribute greatly to manifesting a vision of black American life that expressly prevents blacks from achieving the same level of respectability and acceptance as whites, regardless ...
