For this paper, we choose to investigate address terms used in the dialogues of characters in Margaret Mitchell’s novel Gone with the wind (Macmillan Publisher, 2005) and its Vietnamese translation Vu Kim Thu translator’s Cuon theo chieu gio (Thoi Đai Publisher, 2009). This novel was translated into Vietnamese by some authors such as Duong Tuong, Le Cong Thanh. In this thesis, we selected the translation of by Vu Kim Thu translator (Thoi Đai Publisher, 2009).

• Note: – The Internet is based on IP addresses – Data link protocols (Ethernet, FDDI, ATM) may have different (MAC) addresses • The ARP and RARP protocols perform the translation between IP addresses and MAC layer addresses • We will discuss ARP for broadcast LANs, particularly Ethernet LANs

Trypanosoma cruzi, the parasitic protozoan that causes Chagas disease, contains a major cysteine proteinase, cruzipain. This lysosomal enzyme bears an unusual C-terminal extension that contains a number of post-translational modifications, and most antibodies in natural and experimen-tal infections are directed against it. In this report we took advantage of UV-MALDI-TOF mass spectrometry in conjunction with peptide N-gly-cosidase F deglycosylation and high performance anion exchange chroma-tography analysis to address the structure of the N-linked oligosaccharides present in this domain. ...

TheNS5Bproteinof the classical swine fever virus (CSFV) is the RNA-dependent RNA polymerase of the virus and is able to catalyze the viral genome replication. The 3¢ un-translated region is most likely involved in regulation of the Pestivirusgenome replication. However, little is known about the interaction between the CSFV NS5B protein and the viral genome.We used different RNA templates derived fromthe plus-strand viral genome, or theminus-strand viral genome and the CSFV NS5B protein obtained from the Escherichia coliexpression system to address this problem....

Efforts to isolate carrier protein-mediated synthases from natural product-producing organisms using reporter-linked post-translational modification have been complicated by the efficiency of the endogenous process. To address this issue, we chose to target endogenous phosphopantetheinyl transferases (PPTases) for inhibitor design to facilitate natural product syn-thase isolation through a chemical genetics approach.

As described in Section 2.5 of the textbook, the Domain Name System (DNS) translates hostnames to IP addresses, fulfilling a critical role in the Internet infrastructure. In this lab, we’ll take a closer look at the client side of DNS. Recall that the client’s role in the DNS is relatively simple – a client sends a query to its local DNS server, and receives a response back. As shown in Figures 2.21 and 2.22 in the textbook, much can go on “under the covers,” invisible to the DNS clients, as the hierarchical DNS servers communicate with each other to...

NAT (Network Address Translation) là một chức năng của Router, cho phép chuyển dịch từ một địa chỉ IP này thành một địa chỉ IP khác. Thông thường NAT được dùng để chuyển dịch từ địa chỉ IP private sang IP public, cho phép các host từ mạng bên trong truy cập đến mạng công cộng (internet). Vị trí thực hiện NAT là nơi (router) kết nối giữa hai mạng.
