Define inhibitory postsynaptic potential (IPSP) Solution An inhibitory postsynaptic potential (IPSP) is a kind of synaptic potential that makes a postsynaptic neuron less likely to generate an action potential. This is due to the binding of neurotransmitters with the postsynaptic receptors, causing the opening of ion channels resulting in hyperpolarization. This causes the firing of an action potential from the postsynaptic cell to be less likely..

What are the security requirements and challenges of Grid and Cloud Computing? Solution security issues: A. Policies: 1) Inside Threats: good supervision should be done for having trusted employees . 2) Access Control:Digital signature can be implemented for access control. 3) System Portability: The problem of vendor lock-in should be handled . B. Software Security: 1) Virtualization technology: up to date version of virtualization product should be installed for the security reasons. 2) Host Operating System:should be up to date and secure from hackers 3) Guest Operating System: should be up to date and secure from hackers 4) Data Encryption:should be done on all the data for its safety. C)Physical security: 1) Backup:Either a backup plan should be provided automatically for each customer, or they can use the plans provided elsewhere in the cloud. 2) Server Location:It should be at appropriate place. Room should have adequate space and isolated. A Cooling System and Fire Suppression System should be installed there. 3) Firewall: Cloud Computing service providers should provide a complete firewall solution to their clients. Challenges: A)No clear standard:Grid computing uses various standards, but all grids are not use same standards. Example all grid operating system such as Linux, Apache,and My SQL are using WSRF, WWW, SOAP and XML standards. B)Distributed computing Vs Grid computing: Grid computing involves dynamic virtual organisation, resource sharing and peer to peer computing. The Grid intends to make access to computing power, scientific data repositories and experimental facilities as easy as the Web makes access to information. Same all facilities provide the grid computing. So it is a challenge for grid computing. C)Lack of grid enabled software: The software, which are enabled the grid computing are less, It has limited software on Grid. Much software has not copyright issues and source code of licence. It is need for more company developing grid-enabled version, need more developers on grid development and need to develop open source software. D)Sharing Resources between Various types of Services:Grid used for sharing resource from various sites and grid hosts. It handles a massive amount of data as a grid platform. A lot of sites and multiple servers gathered there it is so complex infrastructure. It provides difficulty for hardware resource sharing within virtual organisation..

The organization of interrupted genes is often conserved between species. What does this mean and what is an example of this conservation (diagram/explain)? Solution First we have know about interrupted genes is often conserved between species,the intricate cellular machinery that converts genetic information into functional protein and RNA molecules and the many ways in which gene expression is regulated by the cell,we discuss some of the ways that genes and genomes have evolved over time to produce the vast diversity of modern- day life forms on our planet uncovering an astonishing wealth of information about the family relationships among organisms and evolutionary mechanisms,but the great revelation of the past 20 years has been the discovery that the actual nucleotide sequences of many genes are sufficiently well conserved that homologous genes. The recognition of sequence homology has become a major tool for inferring gene and protein function thus it is often possible to predict the function of a gene in humans for which no biochemical or genetic information is available simply by comparing its sequence to that of an intensively studied gene in another organism. Gene sequences are often far more tightly conserved than is overall genome structure as discussed features of genome organization such as genome size,cells do not have specialized mechanisms for creating changes in the structures of their genomes evolution depends instead on accidents and mistakes. Introns can be detected by the presence of additional regions when genes are compared with their RNA products by restriction mapping or electron microscopy The positions of introns are usually conserved when homologous genes are compared between different organisms but the lengths of the corresponding introns may vary greatly..

Resistance A primitive adaptive immune Zone of inhibition The ability of a microbe to grow Bacterial lawn Bacteriophage or Enrichment Dense, solid growth across the surface of a petri dish. A lawn of bacteria is prepared and filter disks containing antimicrobial agents are applied A molecule that specifically kills or inhibits bacterial cells Mixture of a bacterial host culture, viral sample, and bacterial media A primitive adaptive immune response in bacteria; that is, bacteria can \"learn\" to become resistant General term to describe a molecule or substance that kills or inhibits microbes The ability of a microbe to grow in the presence of an otherwise toxic molecule, such as an antimic Dramatic change in population-level genetics, in response to a selective pressure A kind of virus that preferentially and exclusively infects bacterial cells A circular clearing within a lawn of growth; surrounding a disk or colony containing an antimicrobial Solution The basic principle of Enrichment is that of selection. Enrichment culture provides favourable growth conditions for the organism of intrest and unfavourable conditions for the competing organisms. This technique can be used in many ways. for example, if we want to culture a thermophile bacteria, incubate the sample at high temperature i.e., at above 55 degrees centigrade because at that temperature, only the thermophilic bacteria can grow while this temperature hampers the growth of other bacteria in the sample. Likewise, enrichment culture may also contains antimicrobial agents to which the selective organism is resistant hence the required organism\'s growth is facilitated hampering the growth of other organisms which are not resistant to the antimicrobial agent. Enrichment culture may also contains pesticides or N2 (used for selective growth of nitrogen fixing bacteria) depending upon the type of microorganism selected. Hence the Answer is a lawn of bacteria is prepared and filter discs containing antimicrobial agents are applied..

Q1) Show what part of SSL that protects against the following attacks :- a. Replay Attack: Earlier SSL handshake messages are replayed. b. Man-in-the-Middle Attack: An attacker interposes during key exchange, acting as the client to the server and as the server to the client. c. IP Spoofing: Uses forged IP addresses to fool a host into accepting bogus data. Q2) Describe the port forwarding operation. Using an example, describe the cases when it is very useful, and the cases when it is very dangerous. Solution The secure socket layer (SSL) is a computer networking protocol that manages server authentication, client authentication and encrypted communication between servers ant client . PROTACTION FROM REPLAY ATTACK- The SSL itself is protected againsts replay attack using Medium Access Control ( MAC ). By using MAC secret and the sequence number it ensures the communication integrity. ssl handshake protocol PROTECTION AGAINSTS MAN-IN-THE MIDDLE ATACK- SSL is based on public/ private key cryptography. This basically means that there is a key pair. The public key is used for encryption and secret key is used for decryption . A certificate is basically a public key with a label identifying the owner. So when your browser connects to an https server , the server will answer with its certificate. The browser checks if the certificate is valid- 1: The owner information needs to match the server name that the user requested. 2: The certificate needs to be signed by a trusted certification authority. if one of these condition is not met, the user is informed about the problem. PROTECTION AGAINSTS IP SPOOFING- An SSL certificate is specific to the particular domain for which it was created regardless of the IP address of the doimain. So if a malicious entity want to attempt to redirect trafiic for a certain website to their own malicious site through IP spoofing techniques. The fake site would not have a SSL certificate that was accurately registerd to the real website.This can be varified through a browser by viewing the certificate information and if the wrong address is shown, then the user will know that they are not on the site they think they are on.Secure Socket Layer Architecture ssl handshake protocolssl change cipher protocalssl alert protocolHTTPSSL record protocolTCPIP.

Please make sure you write about Republic of Turkey otherwise please don\'t waste your and my time. Thanks!! Give an example of Republic of Turkey\'s regional economic integration and identify several potential benefits and several potential drawbacks of regional integration for Republic of Turkey. Elaborate on the protocols of the regional agreement. Solution Turkey’s need for foreign markets in 1980s led the country to strengthen regional cooperation with trading partners worldwide. Trade ties with Middle East received particular attention under Ozal. Business people also worked to improve trade ties with North America, East Asia, and Eastern Europe. Turkey’s increased attention to Middle Eastern markets boosted export of manufactured goods and construction services. The Ozal government made a formal application to EC membership. The European Commission issued an official opinion on the Turkish application but proposed that negotiations should not commence until 1993. Negotiations thereafter led the EU to vote for Turkey’s inclusion in the free trade area in 1995. The steady liberalization of the economy and integration begun by former President Ozal has continued without interruption. Some observers have postulated that admitting Turkey into EU would have some negative effects. One that the level of industrialization in Turkey lags behind the European countries, that the degree of budgetary transfers to lift Turkey to the levels of even the poorest European countries would place a huge burden on Europe’s resources, and that given entry would mean permitting labor mobility. They were also sceptical about human rights policies of Turkey. Despite several setbacks, Turkey has been designated a major emerging market by the main international financing centers. Most observers have instilled confidence in the economy because a large proportion of foreign investments has gone into industrialization. It has also been acknowledged the government’s ability to steer the economy toward the objective of making Turkey a major regional and international industrial power. *****.

Lec 10: 1. The nervous system is divided into the central nervous system and peripheral nervous system. 2. The basic function of a neuron is to receive the information and send a signal to other neurons, muscles, or glands. First, a neuron receives information from the external environment or from other neurons. Then, the neuron integrates, or processes the information from all of its inputs and determines whether or not to send an output signal. 3. The dendrites and axon are thin cytoplasmic extensions of the neuron. The dendrites, which branch out in treelike fashion from the cell body, are specialized to receive signals and transmit them toward the cell body. The single long axon carries signals away from the cell body. The cell body (soma) is the enlarged portion of a neuron that most closely resembles other cells. Nodes of Ranvier are a gap in the myelin sheath of a nerve, between adjacent Schwann cells. 4. Ion channels and direction: As an action potential travels down the axon, there is a change in polarity across the membrane. The Na+ and K+ gated ion channels open and close as the membrane reaches the threshold potential, in response to a signal from another neuron. At the beginning of the action potential, the Na+ channels open and Na+ moves into the axon, causing depolarization. Repolarization occurs when the K+ channels open and K+ moves out of the axon. This creates a change in polarity between the outside of the cell and the inside. The impulse travels down the axon in one direction only, to the axon terminal where it signals other neurons..

How will you choose to contribute to the public good over not contributing, and what factors must be considered. Solution Public goods are goods that everyone (contributors and non-contributors alike) can enjoy, once they are provided. Casual observations in economic system highlights that sometimes people choose to contribute to the public good over not contributing, even when we recognize the pull to free ride on the contributions of others. This contribution can be in the following forms: effort in work teams, provision of tangible or intangible public goods, the use of natural resources (the tragedy of the commons), contributions to charities, tax honesty, buyer-seller relationships, employer-employee relationships. The explanatory factors which motivates people to contribute may be efficient coercion, selective incentives, institutional structure, government trustworthiness, social norms, social capital, ethical reciprocity, and dispositions.
