...June Hayden R. Sinson Ramon Magsaysay High School - Espaǹa Arturo A. Tolentino, Caloocan City Science High School The study of development has been greatly aided by the use of the chick embryo as an experimental model. It is necessary to open the eggshell and reclose it without perturbing the embryo's growth. The embryo can be examined at successive developmental stages by re-opening the eggshell. Protocol Maintain at 37°C with relative humidity that was set above 60%, remove the eggs from the incubator. Turn eggs 90 degrees so that the large base lies horizontal where your embryo is located. Saturate a stack of nonsterile gauze with 70% ethanol. Use two to three pieces to swab up to 5 eggs. Discard when the gauze is soiled. Cut and place a 1" x 1" piece of plastic tape just left of the base to protect the area where the albumen will be drawn out. Use the point of a pair of scissors to make a small hole in the middle of the tape. Using a 10 cc syringe with an 18gauge, 1-inch needle, slowly drill the needle through the hole made by the scissors. Drive the needle down at a 45°C angle towards the bottom of the egg. Tilt the needle towards the center and draw up 3 to 4 mL of albumen. Cut a 3" x 3" piece of plastic tape and stretch it to fit on the top of the egg. Extend the corners of the square around the rounded ends of the...

...dehumanization of Arabs as a threat to society and to stress the immediacy with which Americans must act against to such dangers. In this scene, 24 employs film analysis elements including windowing and time stamps to manipulate time in a way that emphasizes the immediacy of these actions and alters time as if it were real-time in order to show how Middle Easterners are often “othered” in a post-9/11 world. After the President of the United States has learned of the impending terrorist attack that is to occur in Los Angeles later that day, he says to a colleague that “there is a terrorist with his finger on a trigger, and [they’ve] got to get him.” While he is giving this statement, the episode employs a windowing effect in which the president is speaking in the top half of the screen and a Middle Eastern man, named Reza Naiyeer, is presented on the bottom half while he is driving in a convertible and speaking Arabic on the phone. The use of windowing in this scene helps present time as compressed by placing these two separate events simultaneously in the same screen, thus leading the audience to believe that these two events are related and that the Middle Eastern man is a terrorist involved in the anticipated attack. The placement of the president on top of Reza in this compressed windowing effect also exemplifies a portrayal...

...Sam Jones Computers and Applications March 26, 2012 The main desktop features icons, windows, toolbars, folders, wallpapers, and desktop widgets. Desktop environment provides drag and drop functionality and other features, which make the desktop metaphor more complete. Overall, a desktop environment is to be an intuitive way for the user to interact with the computer using concepts, which are similar to those used when interacting with the physical world, such as buttons and windows. Window manager is computer software that controls the placement and appearance of windows within a windowing system in a graphical user interface. Most window managers are design to help provide a desktop environment. They work in conjunction with the underlying windowing system, which provides required functionality such as support for graphics hardware, pointing devices, and a keyboard. I currently have Windows 7 operating system. One of my favorite features of Windows 7 is the Windows Media Center. By clicking on the start button and typing in "media center" and you are watching TV, another great feature is speech recognition which allows you to plug a micophone into your computer and give commands to your computer.

...QUESTION NO: 57 New switches have been purchased for a network upgrade. The objective for the network design emphasizes efficient, error-free transport instead of fast transport. Which switching mode should be configured on the new switches to provide error-free transport to the network? A. cut-through B. fragment-free C. frame-filtering D. store-and-forward E. 802.1q forwarding F. VTP transparent mode Answer: D Explanation: The Switch receives and stores all bits in the frame before forwarding the frame. This allows switch to check the FCS before forwarding the frame. FCS is Ethernet Trailer. Incorrect answers: A. The Switch performs the address table lookup as soon as the destination address field in the header is received. The first bits in the frame can be sent out to out port before the final bits in the incoming frame are received. This does not allow the switch to discard frames that fail the FCS check. B. This is also same as A. But Switch waits 64 bytes to be received before forwarding the first bytes of the outgoing frame. Collisions may occur during first 64 bytes of the frame. Frames in error due to collision will not be forwarded. The FCS still cannot be checked. C,E,F : They are not related to Switch mode transport. QUESTION NO: 107 Which protocol admin overhead in a switch network by allowing the configuring of a new VLAN to be distributed to all the switches in a domain? A. STP B. VTP C. GVRP D. SNMP E.

...retransmit dropped packets, maintain ordering, and check for errors. A TCP connection is established with a three-way handshake in which a connection is established and acknowledged. What are the three messages that form this handshake sequence? Why is this important for establishing the connection? Use your textbook and Internet research to compose your answer. The messages that are used to form the handshake are SYN, SYN-ACK, and ACK. They are important because it allows for both ends to initiate and communicate using different TCP sockets at once. 10.1.2 By establishing a TCP connection, you allow one host to verify expected communication to and from the connected host. This provides two important features: windowing/sequencing and error checking/recovery. Windowing and sequencing are used to determine whether messages have been seen and are delivered in the correct order to the recipient. Error checking makes sure that all the packets are delivered as expected, providing reliability. Why are reliability and sequencing important in message delivery? Give an example of when each would be necessary. Its important because it allows for the organization of multiple messages so that the right message is sent in its proper order. Sequencing is the other important part because it makes sure things are in order and also that they are received in the right time frame and order. 10.1 Review 1. Why is the IP address not needed at the transport layer of communication? Justify...

The proposed technique contains three modules those are preprocessing module, optimization module, and optimization module. 2.1 Preprocessing Module In this module, the input signals is prepossessed first we using windowing technique and followed by the Fourier transformation [5]. Initially the signal is split the input signal as overlapping frames, and each frame contains the duration of 0.025ms. The block diagram of preprocessing module is shown in below fig1. Fig. 1. Block diagram of speech signal enhancement The input speech signal is denoted by S by having a total duration of T ms and the frames be represented by Fi, where 1 ≤ i ≤ T/0.025 each having 0.025 ms. It can be represented by S = {F1 F2……… Fη}, when η=T/0.025 the frames are windowed by using the hamming window technique. By sing the hamming window technique we can eliminate the unwanted signal components and to get sharper peaks. By using the hamming window technique we minimize the maximum side lobes. And the function is defined by: hm(k) = a – b cos(2πk/k-1) …...(1) Where, a=0.54, b=0.46, K is the width of the samples in the symmetrical window is function and M is integer for 0 < m < M-1.

...versatility, hardware independence, and reduced development times. Java’s “write once, run anywhere” (WORA) feature means once an application is integrated with Java, it will run on any platform and device. The WORA capability is the most popular and well known feature Java has to offer. Java was created with unique security features, for example, unsecure code can be downloaded and run securely without the potential to harm your device as the host system cannot become infected with malicious programs; this is possible because a Java program is not directly installed onto your device, but is executed by the Java Virtual Machine (JVM) instead essentially acting as a filter. Java supports graphic user interfaces (GUI) via the Abstract Windowing Toolkit (AWT). AWT is the original GUI toolkit made for Java and introduced along with JDK. AWT provides support for graphics programming and working with IDE’s (Integrated Development Environment). IDE’s support the development of UI’s using drag and drop features to pull components from a toolbar and developing codes for the programmer. These features make creating GUI applications easier for the programmer utilizing the Java platform. Between Java’s WORA capabilities, versatility, less debugging, Java’s superior security, and the ease of GUI development, it’s not difficult to see why it’s the preferred programming language. With full HTML5 integration around the corner,...

...solution describes the elements that make up the design, their responsibilities, relationships and collaborations. The solution does not describe a particular concrete design or implementation because a pattern is like a template that can be applied in different situations. • The consequences are the results of applying the pattern. Although consequences are unvoiced, when we describe design decisions, they are critical for assessing design alternatives and for understanding the costs and benefits of applying the pattern. Model View Controller This paradigm was used to invent user interfaces in Smalltalk. Smalltalk is the consequence of several great ideas that emerged fromXerox PARC. This idea includes the mouse and using a specific windowing environment. Smalltalk is a good language that provides the foundation for all object-oriented languages that followed. The problem with previous paradigms is that the Model, View and Controller used to be squashed together in a single entity. For example, a certain single object would have attained all 3 of the components. With the MVC paradigm, these 3 components have separate and distinguished interfaces. Therefore, if you want to change the user interface of an application, you hence only have to change the view. ...

A high-level language is what most programmers’ use, because of its reconizability since it may contain some English terms that we humans can understand. To convert a high-level language to machine language, you'll need a compiler and linker. 6. A compiler takes all of the code and translates it into something a computer can understand. This compiled code is then executed or saved to a file to be executed at a later time. Interpreter takes code and translates it line by line and doesn't save the translated code in a file. 7.
