...In fact, there a lot of just reasons, that highlight how the lighting and the color scheme go together and influence one another: Natural daylight shows the color in its original quality; Bright lighting brings out warmer tones and more shades of yellow; Fluorescent lighting casts a more blue-ish tone. All this means is that a strong color might be too bright and overpowering when used on all walls or next to a set of windows. So it might be effective to use such color schemes as an accent wall, which is not exposed to a direct sunlight all the time. Learn the Color Terms On top of that, this whole "color scheme" science actually have an expanded terminology of its own! Hue is what we call a color. Red is the hue; blue is the hue. The value of the hue depends on how light or dark it looks to be. Saturation means just how dominant the hue is. As we go from red to pink, the red hue starts to appear less dominant. Intensity is the brightness of the color. The pure colors such as red are more intense than the combined colors such as yellow-green. A color that's more intense usually has a more dominant...

Which one would you find fossils in and why would you find fossils in this rock. Explain how fossils form. (6.E.2.4) Answer: Metamorphic Sedimentary Igneous You would find fossils in sedimentary rock Layers of soil are laid down on dead animals or plants embalming them. The minerals replace the organic matter creating the fossil. 2. Describe how the revolution of the Earth around the sun affects the seasons. Give one example supporting your answer (6.E.1.1) Answer: Revolution is defined as the orbital path a celestial body follows around the sun, or other celestial body. AS the Earth is close to the sun, the sunrays are able to reach the Earth a short distance allowing the Earth to become warmer. When the Earth moves away from the sun, the rays do not reach the earth. The Earth at a persistent distance does not allow the Earth to warm causing a change in seasons. 3. Contrast the differences between lunar and solar eclipses and the affects they have on Earth.

...were unknown. Gram staining is a method that is used by many scientists in order to identify unknown bacteria’s via the unique physical and chemical characteristics of their cell walls. In a gram test a bacteria can either be gram positive or gram negative. The Gram-positive bacteria have an intricate set of amino sugars which we call peptidoglycan that form a thick cell wall around the plasma membrane. On the other hand, Gram-negative bacteria have an uncomplicated cell wall which thus has less peptidoglycan. The main source of identification within the Gram test is the fact that Gram-positive bacteria appear blue-purple while Gram-negative bacteria appear pink (Gram Stain). Bacteria can come in one of three different shapes; spirilla (spiral-shaped), cocci (round-shaped), and bacilli (rod-shaped). In order to be able to see these shapes a bacteria must be stained or dyed. I hypothesis that we will have one Gram-positive culture and one Gram-negative culture. (Lab Manual) In order to prepare this lab experiment we performed five steps. The first step in preparing this experiment was to heat fix a bacteria culture sample which in return stopped the sample from coming off the slide during the experiment. In order to perform this first step we first turned on a Bunsen burner and set the flames to a blue color which was used to sterilize an inoculating loop. Next, a drop of water was added to the slide using the loop which was again sterilized via the Bunsen burner. After, bacteria...

...History without context is little more than the recitation of unrelated events, and history without specific events is little more than a fanciful narrative; therefore, history exists as an interrelated duality between specific events and context. It is through the eyeglass of this apparent duality that the great accomplishments of science come firmly into view and the haziness of opinion and speculation are carried out of focus. Accordingly, Mary Whiton Calkins's life and research is best understood within the context of her upbringing and the zeitgeist of the time towards women, within the framework of self observation, the method of natural science, and associationism; and as the original thinker behind paired-associate learning and the partial resolution of the structuralism/functionalism controversy. Mary Calkins was 57 years-old before she was legally able to vote in the United States of America. Up until the early 20th century the role of woman was universally agree to be exclusively as a wife, mother, and caretaker for the elderly in the family (Goodwin, 2005). In fact, it was widely agreed that any intellectual pursuit beyond primary school could be physically harmful to women. However, by the time Calkins was 25 she was fluent in English, German, French, and Greek; well-traveled and well-read, and a graduate of Smith College in western Massachusetts. Mary Calkins was the eldest of five siblings and the daughter of a Congregationalist minister. The friction between...

...Belal Humanities 7 April 2012 The Ming Dynasty’s Great Wall of China The Great Wall of China is one of the most creative pieces of work known to mankind. The construction of the wall began more than two thousand years ago. The construction of the wall was constructed by at least twenty different dynasties. The main purpose of the wall was to stop barbarians from the north from invading China and the Silk roads. The Silk roads were the main ways of traveling and for trading. A combination of many walls, referred to as the Great Wall of China, were built since the 5th century BC. The most famous is the wall built between 220 BC and 200 BC by the first Emperor of China, Quin Shi Huang. Little of it remains, it was much farther north than the current wall, which was built during the Ming Dynasty [“Great Wall Origin of the Great Wall | History.” Great Wall of China, History, Gallery of Pictures, Travel Guide, News, Discovery and Research]. The protective walls across northern China are on a scale that dwarfs every other construction project on earth. The walls travel through all kinds of terrain, beneath the sea, over jagged mountain ranges, and into forgiving deserts. The wall builders faced endless challenges and found ingenious ways to overcome them. The great majority of construction required the workers to haul sand and other supplies on their backs up steep hills for hours on in. The Great Wall is a testament to human achievement that exceeds any accomplishment...

...TAXONOMY (From ancient greek: τάξισ taxis, "arrangement", and -νομία -nomia, "method") is the science of defining groups of biological organisms on the basis of shared characteristics and giving names to those groups. 5 KINGDOMS Kingdom is the highest rank used in the biological taxonomy of all organisms. There are 5 kingdoms in taxonomy. Every living thing comes under one of these 6 kingdoms. The six kingdoms are Monera, Protista, Fungi, Plantae, and Animalia. 1. KINGDOM MONERA [10,000 species]: Unicellular and colonial--including the true bacteria (eubacteria) and archaebacteria. ndividuals are single-celled, may or may not move, have a cell wall, have no chloroplasts or other organelles, and have no nucleus. Monera are usually very tiny, although one type, namely the blue-green bacteria, look like algae. They are filamentous and quite long, green, but have no visible structure inside the cells. No visible feeding mechanism. They absorb nutrients through the cell wall or produce their own by photosynthesis. a. Archaebacteria - The archaebacteria kingdom (Archaebacterium in Latin) is made up of single-celled organisms and the name of the kingdom means “ancient bacteria.” Scientists actually believe that members of the archaebacteria kingdom were among the first life forms on Earth billions of years ago. These species lack cell structure and their genetic material is not contained inside of a nucleus. The cells of archaebacteria are called prokaryotes. Archaebacteria...

...We call depression "the blues" in the black community. We have been taught, at least in the past, and, to a certain extent even now, to shrug off this mental state. For many of us, it is not just a fact of life; it is a way of life. When bluesmen used to sing, "Every day I have the blues" or "It ain't nothing but the blues" or similar words from hundreds of songs, they do more than mouth lyrics. They voice a cultural attitude. They state an accepted truth at the heart of their music: Having the blues goes along with being black in America. In addition, from the time we are young boys, black males have ingrained into us an idea of manhood that requires a silence about feelings, a withholding of emotion, and ability to bear burdens alone, and a refusal to appear "weak." The internal pressure to adhere to this concept of masculinity only increases as we sometimes experience various forms of racism in a society that historically has sought to deny us our manhood. The internal wall that often keeps black men away from psychotherapy goes along with external barriers built just as high, if not higher. Mental health practitioners are overwhelmingly white, with the proportion of black psychiatrists, psychologists, and psychoanalysts estimated at less than three percent of the nation's total. This would mean that even if black men were to break through the self-imposed barriers and seek professional help for mental issues, it may be difficult to find someone with whom they can build...

...Missouri, Warrensburg stated that, Color has been shown to affect mood and productivity in a variety of different situations. This study evaluated the performance of students in readiness-assessment quizzes in business communication classes, comparing the grades of students whose test papers were white with grades of students who received pastel-colored test papers. The results revealed that there was no significant difference between the two groups. Other research suggests that color may, however, have an effect in other situations [1]. Mehta and Zhu (2009) have published studies that they claim clarify how red and blue differently affect performance on detail-oriented versus creative tasks with strong implications for test preparation and testing formats [2]. According to Sinclair (1998), students taking exams on blue and red paper performed more effectively on blue, especially for complex questions [3]. Whitfield and Wiltshire, in their critical review of the field, discounted the work done before 1950 because it didn’t consider even the three basic components of color (hue, value, and chrome). They also identified flaws in most subsequent research: inconsistencies in the terminology used by respondents to express preferences; lack of attention to surround color (as well as sample color); disregard of the effects of illumination; lack of discussion of size, shape, texture, and complexity of the objects used to present sample colors; and the lack of control for how the very...

Lecturer, Computer Science and Engineering, JECRC Jaipur, Rajasthan, India, (sachingupta.cse@jecrc.ac.in) 2. 1. Abstract: ‘Sixth Sense’ is a wearable gesture interface that augments the physical world around us with digital information and lets us use natural hand gestures to interact with that information. Steve Mann is considered as the father of Sixth Sense Technology who made wearable computer in 1990. He implemented the Sixth Sense Technology as the neck worn projector with a camera system. Then his work was carried forward by Pranav Mistry (Ph.D student in the Fluid Interfaces Group at the MIT Media Lab) [1]. Sixth Sense Technology may change how we look at the world forever. Sure, it is a system that projects information about what surrounds you over objects' surfaces, but it's also much more. By using a camera and a tiny projector, Sixth Sense sees what you see and visually augments any surfaces or objects we are interacting with [1]. The camera and the projector are coupled with a smart phone which acts as the computer and connected to the Cloud, all the information stored on the web [2]. It project information onto surfaces, walls and physical objects around...
