Aperture

editing pictures, I was unable to pursue the interest. I was nervous at first, a lot of the students there were in their second year and many of them had part time jobs in industry. It took a lot of work, but I started to understand exposure and aperture, how to get lighting to convey a message, and how use Photoshop and develop film. Photography is something I enjoyed, and something I miss. It’s able to connect people, capture priceless memories, and walk the line between…

What Size of External Oak Door Do I Need? Oak is an organic, natural and subjectively attractive building material that has been used to build front, rear and interior doors for hundreds of years. There is an unmistakable and unique quality to a solid oak door, which means that, even with their more lofty price tags, they are still the favoured choice of homeowners across the country. Before you spend hours searching for the right door, however, you might want to consider its size, as that last…

Participation at these events goes beyond engaging and interacting with adults, but to encouraging and involving the youth. Many art events attract playfulness, not only for children but through art that encourages engagement between children and adults. Homo Ludens, written by Johan Huizinga in 1938, discusses the importance of the play, as an element of culture and society. Play being a primary and necessary to generate culture. Play is significantly free and freeing from ordinary life. It is…

Connoisseurs often state how “wine improves with age”. Although the process of aging may alter the flavor compounds, texture, or color of the beverage, one cannot predict improvement nor deterioration. Centuries have passed since Edgar Allan Poe describes the death of a gullible fool, yet the taste of a murderer’s Amontillado wine remains bittersweet. Although the work is fictional, “The Cask of Amontillado” provides a realistic, emotional, and dismal libretto, depicted as a tale of revenge and…

An electron vacancy is created and is further filled by an electron from the higher shell and thus an X-ray is emitted to balance the difference in energy between the two electrons. The detector placed on the energy dispersive spectroscope apparatus measures the number of emitted X-rays and their energies. Energy of the X-ray is characteristics of the element from which X-ray is emitted. A spectrum of the relative counts of the detected X-rays is obtained and evaluated for quantitative…

Intracranial Hypertension is a disease process causing increased cerebrospinal fluid or CSF inside the skull. Patients may experience loss of vision and severe headaches resulting from abnormally high CSF pressure. (NORD, 2015). The essential function of cerebrospinal fluid has long been thought to be a fluid envelope that cushions, protects, and nourishes the brain and spinal cord, and recent data shows that CSF plays an essential role in the homeostasis of the interstitial fluid of the brain…

Forensic radiography can be defined as a specialized area of medical imaging using radiological techniques to assist physicians and pathologists in matters related to the law. It can be used in anything from a double homicide case to an accidental drowning case. This new use of imaging helps to decrease the use of an invasive autopsy when it is not needed. However, it is very useful in cases involving a crime of some kind. It can be used for anything ranging from personal identification through…

The bigger the aperture of the lens the more light it collects. They allow objects from a distance to become magnified, clearer, and brighter. Most Refracting telescopes use two main lens, the objective lens, which is a convex lens that are thicker in the middle than the…

In the world richest biotope, wetlands, and specially floodplains, remain particularly active zones in terms of nutrients, biodiversity, flows spreading, sediment transfer and human activities. Today, these sensitive zones are facing increasing human pressures and augmentation in frequency and intensity of extreme hydrological events. The impact of such extreme events on floodplain ecology and biogeochemistry is still difficult to assess. In this context, hydrodynamic models are attractive tools…

The objective of this five-year mission is to provide radar remote sensing data to scientific and commercial users. The satellite’s design is based on the technology and expertise developed in the X-SAR and SRTM SAR missions (Synthetic Aperture Radar). The sensor has a number of different modes of operation, with a maximum resolution of one meter, and is capable of generating elevation profiles. TerraSAR-X is the first satellite that was jointly paid for by government and industry. DLR…
