...DEVELOPMENTAL BIOLOGY The right slant Cell 121, 633–644 (2005)
One of the biggest questions in developmental biology is how embryos that begin as uniform balls of cells end up asymmetric. Experiments in mice provided a clue when researchers discovered that hair-like cilia protruding from embryonic cells in mice rotate, somehow setting up a flow in
the surrounding fluid that defines the left–right axis. A team led by Nobutaka Hirokawa of the University of Tokyo supplies another piece of the puzzle by showing exactly how the cilia’s movement sets up the directional flow. The researchers found that the cilia rotate around an axis tilted 40 backwards. The same rotation was observed in rabbit and medakafish embryos, suggesting that the mechanism, previously studied only in mice, defines asymmetry in other vertebrates. Paraphrasing of Research Highlight: When studying developmental biology researchers found that embryos start as a uniform ball of cells, however, they were questioning why do these embryos end up asymmetric. Research experiments were done on mice, researchers found that the cilia on the embryos on mice rotate and this rotation controls the flow of the surrounding fluid explaining the left-right axis. Further research was done and the experiments showed that the rotation of the cilia on the embryo is rotated 40 degrees backward on an axis. Experiments were also made in rabbits and medakafish embryos and the rotation in the cilia was observed. These results explain...

...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 was collected from a culture tube and smeared onto the slide. We spread the bacteria onto the slide until we reached a milky, pale appearance. After we smeared the bacteria we allowed it to air dry and then passed it through the Bunsen burner...

...Acids, Bases, PH Introduction. This experiment helped to understand difference between acid and base and there PH levels. We learned how to identify buffer. Buffer is substances that resist changes in PH when acid or base is added to solution. Also we learned that water is neutral. Its mean that water has an equal concentration of H and OH. PH number of water is 7. Acid’s PH numbers less than 7. Bases’ PH number is greater than 7. As well we learned how to use and calibrate PH Meter. Materials and methods. For experiment at class we used two solutions, solution A and solution B. First we took PH meter and measured PH level of solution A. After we add to solution A 1.0ml of HCl and record PH level. Total of HCl added was 10 ml, we did it by adding 1.0 ml of HCl at the time. Second time we took solution A and start adding 10 ml(1.0 ml at the time) of NaOH.

...Major Milestones of the Telecommunications Industry 1837 Samuel Morse invents the telegraph - The information age began with the telegraph, which was invented by Samuel F.B. Morse in 1837. This was the first instrument to transform information into electrical form and transmit it reliably over long distances. The earliest form of electrical communication, the original Morse telegraph of 1837 did not use a key and sounder. Instead it was a device designed to print patterns at a distance. 1858 Transoceanic telegraph cable is laid – The transoceanic telegraph cable is an undersea cable running under the Atlantic Ocean used for telegraph communications. The first communications occurred August 16, 1858, reducing the communication time between North America and Europe from ten days, the time it took to deliver a message by ship, to a matter of minutes. 1876 Alexander Graham Bell invents the telephone - The telegraph was followed by Alexander Graham Bell's invention of the telephone in 1876. The magneto-telephone was one of the first telephones on which both transmission and reception were done with the same instrument. 1885 - Incorporation of the American Telephone and Telegraph company (AT&T). After its incorporation in 1885, the American Telephone and Telegraph company dominated the telecommunications market. 1888 - Heinrich Hertz discovers the electromagnetic wave 1895 - Marconi begins experimenting with wireless telegraph 1901 Guglielmo Marconi invented the radio—the...

...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...

The Birth and Evolution of Transistors and Impact on the Transport Industry

...Electronics rely heavily on electronic switching and amplification to generate and capture the various signals which allow them to operate. A controllable valve that allows a small signal to control a much larger signal does this, and could be related to a controllable valve used in the control of water flow. This was once done by a device known as vacuum tube but was later brought down to a much lower production scale for a variety of industrial, economical and business related reasons. Bell Laboratories, the research arm of telecommunications company American Telephone and Telegraph’s (AT&T) director Mervin Kelly put together the first team of researchers and scientists placed on the task of research and development of a solid state-semiconductor later called a transistor that would supersede vacuum tubes and provide numerous advantages. The success of this development would prove to change the computing, electronics and telecommunications systems altogether. Up until the invention of the transistor a vacuum tube was used in the control, amplification and generation of electrical signals. Vacuum tubes are tubes usually made from glass and designed in an airtight manner as to keep the flow of “cathode rays” from external disturbance as they pass from each terminal and laid the foundation for numerous technical innovations, such as the light bulb discovered by Thomas Edison (fig. 1). Joseph John Thomson further made a vacuum tube and placed a third terminal to attain a grasp...

Biol Lab Relationship Between Salivary Amylase & Phosphorylase

...The purpose of this experiment is to examine the effect that enzyme concentration has on reaction time and the effect that substrate concentration has on enzyme reaction. Enzymes are biological catalysts that catalyze different chemical reactions. In general, enzymes are proteins and they are each specific to specific chemical reaction. In order for enzymes to process properly, they should maintain a specific three dimensional structure. When enzymes function, they combine with their substrates (reactant) to form susbtrate-enzyme complex. Then this complex converts into a product and unaltered enzyme. Substrate + Enzyme  Substrate-Enzyme Complex  Product + Enzyme OR Substrate –Enzyme Product (From this equation, in general, the reaction of enzyme is irreversible.) Some of the factors that affect the rate of reaction are temperature, pH, enzyme concentration, substrate concentration, product concentration, etc. The rate of reaction is affected by the level of pH. The extreme level of pH can denature enzyme and result loss of its action. The optimum pH is 14 and this is the level of pH where the rate of reaction is the highest. Temperature also affects the rate of reaction. As temperature increases, the rate of reaction increases as well; however, it increases until the optimum temperature. After optimum temperature, the enzyme denatured. The concentration of enzyme and substrate affect the rate of reaction. In theory, the higher the concentration of substrate, the...

AT&T’s success is garnered by a willingness to function well as an organization, and also by being leaders in innovation. For a company to be successful there has to be proper planning, organizing, leading, and controlling on their part,  coupled by the awareness of internal, and external factors, and how they affect the company.       According to "AT&T" (2012), "We're recognized as one of the leading worldwide providers of IP-based communications services to businesses. We also have the nation's largest 4G network – covering 275 million people, and 2,000 more 4G cities and towns than Verizon, and the largest international coverage of any U.S.” That statement alone says that AT&T has a well defined business plan, and economical external factors, such as their competition will not stand in their way. AT&T has not allowed internal factors like having to find qualified people for the jobs, and then training them affect their “bottom line,” and they understand that the quality of their employees affect their customer satisfaction, and customer satisfaction is key when dealing with a competitive market.
