Steve Jobs, an inventor, entrepreneur and industrial designer of Apple, once said, “The ones who are crazy enough to think they can change the world are the ones that do.” While new inventions often do change the whole world, some change the world for one. Technology has changed the world for everyone; it has changed the difficulties of life and made them easier for mankind. For the colorblind person, the invention of the Enchroma color blind assist glasses has not only changed the way people see

RESEARCH BLOG ENCHROMA GLASSES: We all have different ways of perceiving the world. Going back 3 years most of you may remember the big debate of the blue-and-black or white-and-gold dress. To some of us distant objects may look blurry, to others near objects. Others may see everything blurry! However, most people with these common conditions can either have surgery or wear glasses. The condition I would like to approach however, is one where it is not something that is physically wrong with the

significant factor pertaining to who we are and how we perceive the world around us are influenced by the genes inherited in our lineage. One particular trait that is important in our lives is color vision and color blindness, particularly cone dysfunction syndrome. Cone dysfunction syndrome is a heterogeneous group of inherited disorders resulting from a mutation of photopigment genes (Simunovic 1998). This rare form of visual deficiency can branch from achromatopsia,

While cone-beam computed tomography (CBCT) scans can show more anatomy, provide 3D reconstructions, and generate enhanced treatment plans when compared to conventional dental radiographs, CBCT operation and interpretation should be more strictly regulated because there isn't a defined criterion for who can or cannot purchase CBCT scanners, additional educational training is not required to operate these scanners, and facilities tend to overuse CBCT scanners with little consideration to patient dose

PART I The Elasmobranchs are a subclass of class Chondrichthyes. The Chondrichthyes are classified as the Cartilaginous fishes. Aside from the Elasmobranchs, this class has another subclass named Holocephali which is comprised of the chimaera. The Elasmobranchs are comprised of sharks (Selachii) and the rays and the similarly structured skates (Batoidea) Van-Eyl, S. M., Siebeck, U. E., Champ, C. M., Marshal, J., & Hart, N. S. (2011). There have been fossils of sharks found dating about 400 million

1. The major types of volcanoes are shield volcanoes, scoria cones (cinder cones), and stratovolcanoes (composite). Each of these volcano types is influenced by the volume, the amount of magma, viscosity, a measure magma’s fluid friction, and volatiles or dissolved gases, of the magma that creates them. Shield volcanoes form from the solidification of lava flows of basalt (Abbott 2014). These large volume, low viscosity, low volatiles magma flows travel great distances. As thousands of layers of

Vision is defined as “the sense by which objects in the external environment are perceived by means of the light they give off or reflect” (Saunders, 2007). Vision is very a significant aspect in human life. If an individual is visually impaired, it will cause other developmental delays in that individual including the sensory, motor, cognitive, social and language developments (Texas School for the Blind and Visually Impaired, n.d.). It is already well known that infants are not born with perfect

NOT list every symptom or characteristic. Include only the most relevant and important points. Colour blindness is a disorder where a person has the inability to distinguish between colours, due to missing colour-sensing pigment in the eye’s retina cones. Around 1 in 12 men have this disorder and 1 in 200 women have it. Characteristics of blindness include the different types of it. There are a few different types of colour-blindness, the most common type of colour-blindness which 99% of colour-blind

development of the retinal cones. Cones are photoreceptor cells that response best to bright light and serve to discriminate colors. There are three different types of cones each with different pigments blue, green and red (Deeb). Blue cones are able to absorb light with a short wavelength around 420nm; green cones are able to absorb light with a middle wavelength around 530nm, and red cones are able to absorb light with a long wavelength around 560nm (Deeb). Working together these cones are able to discriminate

Squirrels are everywhere, see figure 1 for an example of the grey squirrels in our area. They skitter through trees above heads, forage in trashcans, and chew through wires. Squirrels are so common the average person could easily overlook their importance. Squirrels have played a significant role in the evolution of seed defenses in pine trees. The evolution of these seed defenses is frequently attributed to birds and other seed predators (Benkman 1994). The ever-present unnoticed squirrel is
