Describe the movement of yeast cells once ingested by a paramecium & what is this movement due to? Solution The movement of yeast cells once ingested by a paramecium is mainly slow propelling & paramecium is a unicellular, macronucleated, motile, ciliated fresh water organism that predominantly survives in freshwater habitats by feeding on the small bacteria, yeasts etc. The type of movement exerted by the Paramecia after eating yeasts is “slow propelling movement by whiplashing cilia”. However, sometimes it may lead to cessation of propelling movement on heavy yeast consumption. This type of movement is due to Chemosensory Signal Transduction.

26. The gecko is a reptile that has the amazing ability to climb smooth surfaces--even glass! Recent discoveries indicate that geckos stick to smooth surfaces via van der Waals interactions between septae on their feet and the smooth surface. How is this method of stickiness advantageous to the gecko over covalent interactions? Solution Answer Geckos are lizardsfound in warm climates throughout the world They belong to the infraorder Gekkota Since Van der Waals interactions are relatively weak compared to covalent bonds Therefore, Van der Waals interactions would stick the gecko to the surface reversibly.

What are the advantages for proteins to form three-dimensional structures using non-covalent (weak) interactions? Solution PROTEIN FOLDING MODELS: 1. Frame work model: In this the protein local elements which are stretches of amino acids liked by one another by covalently with peptide bonds. The region of the primary amino acids sequence in peptide bonds makes different domains. In these domains some of regions are making with Alfa helix and some are beta sheet domains. These primary elements form secondary structure independently of tertiary structure (kim and baldwin).these elements can diffuse un till they collided, successfully adhering and coalescing to give the tertiary structure (diffuse-collision model),(karplus and weaven). 2. The classic nucleation model: It postulates that some neighboring residues in the sequence would form native secondary structure that would act as a nucleus form which the native structure would propagate in a step wise manner. Thus the tertiary structure would form as necessary consequence of the secondary structure (wetlaufer). 3. Hydrophobic collapse model: It is hypothesized that a protein would collapse rapidly around its hydrophobic side chain and then arrange from restricted conformational space occupied by the intermediate. Here the secondary structure would be directed by native like tertiary structure (ptitsyn & kwajima). Leviathan’s paradox: It is formulated by Cyrus Leviathan. There are vast too many different possible conformations for a protein to fold by a random search. Structural organization of protein: 1. Primary Structure: It refers the sequence of amino acids along with the disulphide bonds. 2. SECONDARY STRUCTURE: Alfa- Helices and Beta-Pleated sheets are most frequently occurring in secondary structure in polypeptides. Both of these can case local folding of protein. the Alfa - Helices in polypeptide made up of L Alfa amino acids are right handed, the - Helices is stabilized by hydrogen bonds formed between oxygen and amide hydrogen’s of peptide bonds that are a part of linear sequence. Beta-Pleated sheets: 2 types A. Parallel: in this the adjacent hydrogen bonding segments are connected by cross over connection [Right handed]. B. Anti-Parallel: In this the adjacent hydrogen bonding segments are connected by HAIRPIN turns or reverse turn [Left Handed]. 3. Tertiary structure: It is arisen because of the folding of poly peptides upon itself. 4. Quaternary structure: Some proteins are made up of 2 or more polypeptides chains, the interaction between different poly peptide are subunits gives rise to the quaternary structure. Non-covalent (weak) interactions advantages in proteins: In proteins mainly 4 types of non-covalent interactions are present. 1. Hydrophobic region R-CH3 ------- H 3 C-R 2. H-bonding between R-group G-OH ------ N=R 3. Salt bridge R-COO------ NH 3 -R 4. Van der Waals force The non-covalent bonds, which are present between the peptides, can forms interactions between indivi.

Network peering is a method to save ISP\'s network bandwidth and resources. Write a brief document describing the following: What is meant by \"Network Peering\" What is meant by \"Internet Exchange\" and How is it related to \"Network Peering\". How can \"Network Peering\" save network resources How can \"Network Peering\" be implemented Solution a. Network peering:Network peering is process by which one internet network connects to another directly, enabling a faster throughput and exchange of information. It allows them to directly hand off traffic between each other’s customers, without having to pay a third party to carry that traffic across the Internet for them. Peering is distinct from transit, with a transit connection, the end user or network operator pays another larger network operator to carry their network traffic for them. b. InternetExchange:An Internet exchange is a process of exchanging information from physical infrastructure through which Internet service providers and Content Delivery Networks exchange Internet traffic between their networks (autonomous systems). Internet exchange reduce the portion of an ISP\'s traffic which must be delivered via their upstream transit providers, thereby reducing the average per-bit delivery cost of their service. c. The most common types of network resources in an office environment are hardware, such as printers, fax machines and scanners. Each computer in a network is connected to each piece of hardware wirelessly, making it easy to use the equipment whenever necessary. When it comes to internet the network is very large by using internet connection anyone can transmit or share their data from anywhere. A popular way of sharing network resources is through peer-to-peer transfer. By the process of network peering various number of network resources are saving enormously. Data files are also important network resources shared by those who must collaborate on projects. By sharing information across a network, workers easily can modify and update text documents, spreadsheets and graphic design projects without having to send large files through email or transferring files through portable flash drives. Workers can access files just as if they were on their own computer. d. Network Peering is the arrangement of traffic exchange between Internet service providers (ISPs). Larger ISPs with their own backbone networks agree to allow traffic from other large ISPs in exchange for traffic on their backbones. They also exchange traffic with smaller ISPs so that they can reach regional end points. Essentially, this is how a number of individual network owners put the Internet together. To do this, network owners and access providers, the ISPs, work out agreements that describe the terms and conditions to which both are subject. Bilateral peering is an agreement between two parties. Multilateral peering is an agreement between more than two parties. Peering requires the exchange and updating of rout.

Instructions The first programming project involves writing a program that parses, using recursive descent, a GUI definition language defined in an input file and generates the GUI that it defines. The grammar for this language is defined below: In the above grammar, the red symbols are nonterminals, the blue symbols are tokens and the black punctuation symbols are BNF metasymbols. Among the tokens those in title case are keywords. The character literals are punctuation tokens. Below is an explanation of the meaning of some of the symbols in the above productions that should help you understand the actions that are to be performed when each of the productions is parsed: In the window production the string is name that is to appear in the top border of the window and the two numbers are the width and height of the window In the production for layout_type that define the grid layout, the first two numbers represent the number of rows and columns, and the optional next two the horizontal and vertical gaps In the production for widget that defines a button, the string is the name of the button In the production for widget that defines a label, the string is text that is to be placed in the label In the production for widget that defines a text field, the number is the width of the text field In the production for radio_button, the string is the label of the button You parser should properly handle the fact that panels can be nested in other panels. Recursive productions must be implemented using recursion. Lexical and syntactical errors should be detected and reported (the first error only; after reporting the first error the program must exit gracefully). Below is an example of an input file: Just to give you an idea where that input file came from, the above input file corresponds to the GUI shown below: However, please keep in mind that you are NOT required to re-create the GUI that corresponds to the input file. Instead, you are only required to: 1. Implement a lexer capable of recognizing all the terminal symbols of the grammar (tokens/lexemes - those in blue) 2. Implement a recursive descent parser that (using the lexer from 1.) will be able to parse the input file and detect a syntax error (the first one is enough, then the parser should exit gracefully) 3. As a result of parsing the input file, an output file will be generated, reporting the parsing steps followed by the parser in a manner similar to the one described by Sebesta (10th edition) on pages 181-186. Notes: - You can implement the parser for this grammar in C, C++, Java or C# 9 6 3 8 0 Solution This is the codes: calculator.js calc_array = new Array(); var calcul=0; var pas_ch=0; function $id(id) { return document.getElementById(id); } function f_calc(id,n) { if(n==\'ce\') { init_calc(id); } else if(n==\'=\') { if(calc_array[id][0]!=\'=\' && calc_array[id][1]!=1) { eval(\'calcul=\'+calc_array[id][2]+calc_array[id][0]+calc_array[id][3]+\';\'); calc_array[id][0] = \'=\'; $id(id+\.

How do the following theoretical frameworks of international relation and global politics view states and other actors in the international system: realism, liberalism, Marxism and constructivism? Solution Realism suggests that states should & do look out for their own interest first.Realism persumes that states are outvfor themselves first and formost.Realism suggests that international relations is driven by competition between states and states therefore do and should try to further their own interests.Realists believe that greater power is the only way for states to secure their soverignty and this leads to the belief that states are the main players in international politics because the system discourages individuality in favor of these types of power struggles.Realists believe that power is gained through war or the threat of military action they also believe that there is no such thing as lasting alliances or peace due to this power grabbing system. Liberal theory too believes in the view that states are seeking military power to combat anarchy.For liberal theory there is hope for world peace if state seeks common ground, forming alliances and institutions for policing the world powers.Liberal unlike realists take into account the individual attributes that states possess and allow for the idea of lasting alliances based on comon beliefs and ideas and attribute more power to common institutions then to states.Liberals believe that common ideas can lead states into interdependence and so remove allies as threats to soverignty.They emphasize that the real power for states comes of mutually held ideas like religion ,language,economies and political systems that will lead states to form alliances and become interdependent. Constructivism has been described as a challenge to the dominance of neo liberal and neo realist international relation theories.Michael barnett describes constructivist international relations theories are being concerned with how ideas define international structure how this structure defines the interests and identities of states and how states and non state actors reproduce this structure.The key tenet of constructivism is the belief that international politics is shaped by persuasive ideas,collective values,culture and social identites.The failure of either realism or liberalism to predict the end of the cold war boosted the credibility of constructivist theory.Constructivism most concerns itself with the role of ideas in shaping the international system.By udeas constructivism refer to the goals, threats, fears , identities and other elements of perceived reality that influence state and other elements of perceived reality state and other elements of perceived reality that influence states and non state actors within the international system. Marx saw the world in term of its productive relations sovthat the way in which we organize production theory determines social and political relations as well.Neo-Marxists ap.
