Assess the significance of Austrian and Post-Keynesian criticisms of Essay - 1

Assess the significance of Austrian and Post-Keynesian criticisms of the standard neoclassical view of the competitive process - Essay Example Contextually, neo-classical approach advocates on the existence of perfect competition and market equilibrium. On the other hand, Austrian approach ignores the assumption claimed by the neo-classical approach and emphasizes on claiming that there exists nothing static at the marketplace as the market itself is highly dynamic (Block & et. al., 2002). Similarly, Post-Keynesian approach also firmly rejects the assumption of neo-classical approach and further states that market is about uncertainty and firms at the market place are totally unaware of their future (Lee, 1986). Based on these understandings, the paper intends to identify and assess the various implications of these three approaches in a more elaborated form. Furthermore, the paper also attempts to compare and critique the neo-classical approach in the light of Austrian and Keynesian thoughts of economics. Neo-Classical view of competition is based on the assumption of perfect competition economic conditions. The assumptions of perfect competition can be illustrated as the appropriate conditions which need to be present in the market place in order to ensure the existence of situations acclaiming a perfectly competitive industrial structure (Hunt & Morgan, 1995). Neo-Classical theory advocates the existence of large numbers of sellers in a relatively small market size offering homogeneous products to a significant range of consumers. Furthermore, the theory tends to ensure that all the participants at the market place possess a perfect knowledge of the commodity offered, including price and related costs of each good/service. The theory also intends to achieve the perfect mobility of factors of productions. As a result, during the existence of such conditions, both the producers and customers are in the position to influence the price of the commodities offered at the market place. It is worth mentioning that due to the presence of large

Financial Objective The Financial Objectives that Echeverry Vodka Company will follow are as follows: Every quarter the company

Ethical hacking

Ethical hacking Chapter 1 Introduction Ethical hacking is an emerging tools used by most of the organizations for testing network security. The security risks and vulnerabilities in a network can be recognized with the help of ethical hacking. This research completely concentrates on ethical hacking, problems that may occur while hacking process is in progress and various ethical hacking tools available for organizations. Information is the important source for any organizations while executing business operations. Organizations and government agencies have to adopt ethical hacking tools in order secure important documents and sensitive information (Harold F. Tipton and Micki Krause, 2004). Ethical hacker professionals have to be hired in order to test the networks effectively. Ethical hackers perform security measure on behalf of the organization owners. In order to bring out the ethical hacking efforts perfectly a proper plan must be executed. Ethical hacking has the ability to suggest proper security tools that can avo id attacks on the networks. Hacking tools can be used for email systems, data bases and voice over internet protocol applications in order to make communications securely. Ethical hacking can also be known as penetration testing which can be used for networks, applications and operating systems (Jeff Forristal and Julie Traxler, 2001). Using hacking tools is a best method for identifying the attacks before it effect the entire organization. Ethical hackers are nothing but authorized users for the sensitive information or networks of an organization. Using hacking techniques for handling employees in organization and for solving critical judicial cases is not a crime. An ethical hacker use same tools and actions as performed by normal hacker. The main aspect in ethical hacking is that target permission is essential for performing hacking on the information. Ethical hacking can be used while performing security audits in the organization (Kevin Beaver, 2010). Thus, ethical hacking can help in testing the networks by finding out various vulnerabilities. In ethical hacking, a user will get permission to access the important data. Aims and Objectives Aim To investigate the importance of ethical hacking and its implementation in organizations Objectives Finding the importance of ethical hacking tools Understanding the ethical hacking process Implementing ethical hacking tools in an organization Purpose of Study The main of this research is to recognize ethical hacking tools that can be used in organizations and government agencies. Testing the networks is essential in order to maintain security for the organizational information. The difficulties in networks have to be recognized by the security professional so that they can be solved before effecting the organization operations (James S. Tiller, 2005). This research also focuses on carrying out the ethical hacking tools in a particular organization. The advantages of using ethical hacking in business firms can be evaluated by this study. Ethical hacking tools can be implemented in various fields of applications. Various security professionals can be efficient in ethical hacking tools by undergoing a training process. Another major intension of this research is to identify the importance of ethical hacking professionals in providing security to the networks. (Nina Godbole, 2008). Thus, this research entirely focuses on ethical hacking tools which can be implemented for testing the networks. Research Context This research on ethical hacking can be very useful to many organizations as it can provide clear idea about hacking tools. Security professionals and normal users have to be trained well in order to use hacking tools. The importance of ethical hacking while solving many judicial cases can be identified with the help of this research. Management of an organization can be benefited largely through implementing hacking tools. Hacking tools implementation process can be understood with the help of this research (Ronald L. Krutz and Russell Dean Vines, 2007). Network security or data security engineers in organization will come to know about new ethical hacking methods and techniques that are available in the present market by concentrating on this research. The concepts in this study provide knowledge related to security improvements. Business users can hack the data in order to use it for the purpose of evaluating a correct process. Management has to take precautionary measures while a llowing the professional to hack ethically because data may be misused (Rajat Khare, 2006). Scholars who concerned with information security can take the help of this study for attaining the knowledge on hacking systems. Many organizations are encouraging ethical hacking professionals in order to control their business operations effectively. Email systems, data bases and communication applications can avoid or identify attacks by adopting the hacking tools. Malicious attacks on the information or software can be prevented by implementing this research while using ethical hacking tools. The organizations that concerned with security in networks have to use ethical hacking tools (Greg Meyer and Steven Casco, 2002). Hence from the above discussion it can be understood that, business firms, investigating agencies, government systems and web users can make use of this research to achieve the important information in authorized manner. Chapter 2:Literature Review Ethical Hacking and its importance The word hacking is defined as an illegal use of the others computer system or the network resources. Hacker is the term which is formerly meant for the skillful programmer. This is mostly found in the countries like United States and many other countries. The word hacker refers to the names of the persons who enjoys the work in learning the details of the computer systems and stretch the capabilities from the system (Rajat Khare, 2006). The system of hacking describes the fast improvement in the new programs that make the codes for the providing a better security to the system with more efficiency. The word cracker also belongs to the same field it make use of the hacking skills for the unlawful purposes like email id, intruding into others system. Hacking is of different types such as back door hacking, viruses and worms, Trojan horses, Denial of Services, anarchists, crackers, kiddies and ethical hacking (Kevin Beaver, 2010). In the types of hacking system one of the most common h acking is ethical hacking. This is defined as the services that provides the securities for the customers networks, information assets and identifies the vulnerabilities to maintain the reputation of the corporate sectors before it exploit the company. This type of the hacking system provides the high securities to the customers methodologies and techniques to yield high qualities of infrastructures. The ethical hacking system includes some of the service like: Application Testing War Dialing Network Testing Wireless Security System Hardening Application Testing This is an uncover design or the logic flaws which result in the compromising with the unauthorized accessing of the systems, networks, applications or the information regarding the systems. This application testing is used for investigating and identifying the extent and the criticality of the problems exposure to the thick client (Java) and thin client (web browsers) applications. This application testing includes the services like client-side application testing and web application testings (Joel Scambray, Mike Shema and Caleb Sima, 2006). The client-side application testing is the process of developing the software that is used for the measuring the integrated security into the client software constituents. In this system this testing application is based on the gathering of the information by observer using the reverse engineering system. War Dialing This is one of the services that are provided by ethical hacking. War dialing is a method of dialing a modem number to identify open modem connection that supplies access in a remote way to a network for targeting a particular system (Kimberly Graves, 2007). This word is originated from the day the when the internet has come into the existence in most of the companies. This follows the method of scanning to find the strength of the network connection. The tools of War dialing work on the concept that organizations do not pay attention to dial-in ports like they do towards the firewalls. Network Testing The networking testing services of the ethical hacking provides the information on the exposures of the network, services, and solutions on the convergence, protocols and system devices including the virtual private network technologies. This testing process includes a number of constitutes in external and internal devices. It also analyzes the applications of the voice over Internet protocol within the environment of the organization (Greg Meyer and Steven Casco, 2002). The main goal of the network testing application is to make obvious demonstration of the political effects on its development. By making use of this application into the organization, it provides a complete enlightenment to the work for determining the result in the organization. Wireless Security Wireless security services measures the security in the available architecture to provide a guidelines to ensure the system integrity and accessibility of the resources. The working of wireless security is based on the three phases. In the first phase of the operation it identifies the activeness of the wireless networks (Cyrus Peikari and Seth Fogie, 2003). The team of the ethical hacking demonstrates the exposure to the attackers with the space in the wireless network. In the seconds phase of this system it implements a normal users to evaluate the measures of the security that secures the infrastructures of the organization to control the accessing of the devices. During the third phase the team will try to utilize the discovered threats to gain access on other networks. This provides the security in wireless local area network, virtual private network, intrusion detection system and wireless public key infrastructure. System Hardening The system hardening stresses on the network vicinity. Security is the prime factor that determines the level of integrity of the information and resources used in the computing. Effective deployment of the security controls unauthorized, accidental disruption if resources in information technology (Kevin Beaver and Peter T. Davis, 2005). The system hardening assessment is complemented in three phases. The ethical hacking team will analyze the network to identify the loop holes in security updates and other frequent security defects. Scanning of the remote access devices is done for finding out the vulnerabilities. The configuration vulnerabilities and missing security updates are determined in the initial phase. In the second step the host operating system is examined to determine the services available for remote users and their level of impact. All the TCP/IP services and also the Telnet, FTP, Send-mail, DNS and others are tested (James S. Tiller, 2005). The packet fragmenting and loose source routing are used in an attempt to bypass filtering routers and firewalls. The last phase is complicated as the team uses the information gathered from the first two steps to mine the weaknesses and threats that were identified to gain access to the host system. Before the start of the three steps the boundaries for actions and events are determined. Hence from the above context it can be stated that ethical hacking is a methodology that is used for gathering the information on the hacker. The ethical hacker is the expert who is hired by an organization to solve the problems related to hacking in their network and computer system. Need for Ethical Hacking The process of employing someone to hack ones company is ethical hacking. Ethical hacking is one of the tools that are used to judge the security programs of the organizations. It is also referred as penetrating testing, red teaming, intrusion testing, vulnerability and even security judgments. Each one these has different meanings in different countries. Hacking is also described as new development of the existing programs, software and code. It makes them better and more efficient (James S. Tiller, 2005). Ethical hacker can know the details of computer while hacking and become the security professional. It involves in foot-printing, scanning, tacking all the secured information. Ethical means a philosophy with morality. Hackers hack systems to detect dangerous, unauthorized access and misuse (Shon Harris, Allen Harper, Chris Eagle and Jonathan Ness, 2007). Threat and vulnerability are the two dangers the hacker has to face. The hacking report must be confidential as it should face the organizations security risks. If this goes wrong in any way the organization results in fatal, penalties and loss. For example: computer crime is done by misuse of their hacking skills. The need to hack is for catching the thief. Ethical hacking is the correct method to make your computers work properly (Kevin Beaver, 2010). Ethical hacker needs higher level skills compared to penetration testing. Penetration testing is same as ethical hacking but the hacker uses the penetrating tools and tests the security danger. Ethical hacking is known as White Hat in some of the literature. It tests both the security and protective issues whereas penetrating test mainly leads with the security issues (Asoke K. Talukder and Manish Chaitanya, 2008). Some of the websites and companies offer the training, but they cannot be created they are self-made. Various types of testing need different types of softwares and tools. Game freaks use hacking technology in order to win the game. Hackers will d iscover many ways to hack like trial and error method, operating systems, online and determining the threats. Ethical hacking is done by hackers on behalf of the owners, and in normal hacking they use their skills for personal use (Debra Littlejohn Shinder and Micheal Cross, 2008). Cyber terrorism includes common hacking techniques such like viruses, email bombs and natural disasters. Thus ethical hacking is done by hackers on owners request. Mainly this is seen in corporate companies and organizations. Ethical hacking techniques are used for game cheat codes, hacking accounts and other for good result. Majorly used for fight against cyber terrorism and to take preventive action on hackers Types of ethical hackings Ethical hackers use various methods for breaking the security system in the organizations in the period of cyber attack. Various types of ethical hacks are: Remote Network: This process in especially utilized to recognize the attacks that are causing among the internet. Usually the ethical hacker always tries to identify the default and proxy information in the networks some of then are firewalls, proxy etc. Remote dial up network: Remote dial up network hack identify and try to protest from the attack that is causing among the client modern pool. For finding the open system the organizations will make use of the method called war dialing for the representative dialing. Open system is one of the examples for this type of attacks. Local Network: local network hack is the process which is used to access the illegal information by making use of someone with physical access gaining through the local network. To start on this procedure the ethical hacker should ready to access the local network directly. Stolen Equipment: By making use of the stolen equipment hack it is easy to identify the information of the thefts such as the laptops etc. the information secured by the owner of the laptop can be identified (Kimberly graves, 2007). Information like username, password and the security settings that are in the equipment are encoded by stealing the laptop. Social engineering: A social engineering attack is the process which is used to check the reliability of the organization; this can be done by making use of the telecommunication or face to face communication by collecting the data which can be used in the attacks (Bryan Foss and Merlin Stone, 2002). This method is especially utilized to know the security information that is used in the organizations. Physical Entry: This Physical entry organization is used in the organizations to control the attacks that are obtained through the physical premises (Ronald l. Krutz and russel dean Vines, 2007). By using the physical entire the ethical hacker can increase and can produce virus and other Trojans directly onto the network. Application network: the logic flaws present in the applications may result to the illegal access of the network and even in the application and the information that is provided in the applications. Network testing: In this process it mainly observes the unsafe data that is present in the internal and the external network, not only in the particular network also in the devices and including the virtual private network technologies Wireless network testing: In this process the wireless network reduces the network liability to the attacker by using the radio access to the given wireless network space. Code review: This process will observe the source code which is in the part of the verification system and will recognize the strengths and the weakness of the modules that are in the software. War dialing: it simply identifies the default information that is observed in the modem which is very dangerous to the corporate organizations. Techniques and tools required for ethical hacking Ethical hacker needs to understand how to find the network range and subnet mask of the target system. IP addresses are used to locate, scan and connect the target systems. Ethical hacker also should find out the geographical location of target system. This can be done by tracing the messages that are sent to destination and the tools used are traceroute, Visual route and NeoTrace to identify the route the target (Kimberly Graves, 2007). Ethical hacking should use right tools or else task accomplishment of task effectively is difficult. Many security assessment tools will produce false positive and negative or may they even miss susceptibility to attacks. In case of tests in case of physical security assessments they miss weakness. In order for ethical hacking specific tools have to be used for the task chosen. The easier the ethical hacking will become if many tools are used. The right tool must be used at right place. The characteristics in tools for ethical hacking is it should ha ve sufficient document, detailed reports should be there on the discovered attacks regarding their fixing and explosion, Updates and support. The general tools used for ethical hacking in case to find passwords are cracking tools such as LC4, John the Ripper and pwdump (Bragg, Mark Phodes Ousley and Keith Strassberg, 2004). The general tools like port scanner like SuperScan cannot be used to crack passwords. The Web-assessment tools such as Whisker or WebInspect tools are used for analysis of Web applications in depth. Whereas network analyzer tools such as ethereal cannot give good results. While using the tools for any particular task it is better to get feedback from the simple Google searches such as SecurityFocus.com, SearchSecurity.com and Itsecurity.com will give nice feedback from the other security experts which makes ethical hacking easy and to select the right tool. Some of the commercial, freeware and open source security tools are Nmap (Network Mapper), Etherpeek, Super Scan, QualysGuard, WebInspect and LC4, LANguard Network Security Scanner, Network Stumbler and ToneLoc. The capabilities of many security and hacking tools are often misunderstood, such as SATAN (Security Administrator Tool for Analyzing Networks) and Nmap. The other popular tools used in ethical hacking are Internet scanner, Ethreal, Nessus, Nikto, Kismet and THC-Scan (Kevin Beaver, 2007). Cain and able is a ethical tool used for recovery of windows UNIX problems. This is only password recovery tool handles an enormous variety of tasks. It can recover the password by sniffing the network, cracking the encrypted passwords using Dictionary and Cryptanalysis, recording VoIP conversations, decoding scrambled passwords, revealing the password boxes, uncovering cached passwords and analyzing routing protocols. Ethereal is a fantastic open source tool used as network protocol for UNIX and Windows. It allows examining the data which is present in disk or file and can capture the data. This is also known as Wire shark. It has many powerful features which have very rich display filter language and ability to view the TCP session. Another cracking tool Aircrack is the fastest available cracking tool (John Hyuk Park, Hsiao-Hwa Chen and Mohammed Atiquzzaman, 2009). Thus proper tools and techniques has to be used for better hacking and it will be easier by using more and more tools required. Hacking operating system Linux is the operating system which is most useful software that supports and will be helpful to identify the passwords and uses in detecting interruption there are many software tools are utilized for the hacking and security tools are used for the Linux. The tools which are using in this are not harmful tools this is especially used to protect. John the ripper: John the ripper is nothing but password hacking software technique which is usually used to develop for the UNIX operating system. This the most significant process which is used for password testing as it joins all password crackers into single package and the auto detects password hash types which involves the customizable cracker (Ryan, David R. Mirza Ahmad, 2002). It can be run among the different encrypted password methods which involves various crypt password hash forms where usually found on the different UNIX operating systems that is based on the DES, MD5 etc, Kerberos AFS and windows like XP, 200etc.Generally passwords are placed in the LDAP and other tools. Various types of components are used to expand the capability and for involving the MD4 related password hashes. The other one is the NMAP; Nmap is the used to protect the network. It is especially used to identify the network related services on the computer network by generating the map of the network . Nmap is having the ability to identify the services on the computer network instead of this it never advertises its service detection protocol (James turnbull, 2005). However the Nmap can collect many details regarding the remote computers. This will involve the operating system, and uptimes etc are the software products that are used to execute the service, and are used to involve on the local area networks and also on the dealer of the remote network card. Nmap can be run on the linux. Linux is the most important operating system and the windows are the second most important operating system. The other operating system used is Nessus, this software is used to scan the virus. The main aim of this software is used to identify the virus on the tested system such as; the virus will permit the data on to the network (Mark Carey, Russ Rogers, Paul Criscuolo and mike Petruzzi, 2008). Default passwords are utilized on the network accounts. This software is also called as the external to ol which is used to launch the attack. By making use of the mangled packets rejection of the service among the TCP/IP can be done. Nessus the best software used to scan the virus. Many organizations through out the world are using this software. The check Rootkit is the normal program which helps the administrator to check their system for the known rootkits ( James Turnbull, 2005). This program is the shell script by using the LINUX tools similar to the strings and the grep commands to seek out to carry out the core programs for the signatures with the executed process status command to look for inconsistency. This program alternatively use own commands to run. This tool will permit check rootkit to get confident the commands upon which it depend a bit more. Applications and resources Ethical hacking is nothing but the one which performs the hacks as security tests for their systems. Ethical hacking can be used in many applications in case of web applications which are often beaten down. This generally includes Hypertext Transfer Protocol (HTTP) and Simple Mail Transfer Protocol (SMTP) applications are most frequently attacked because most of the firewalls and other security are things has complete access to these programs from the Internet. Malicious software includes viruses and Trojan horses which take down the system. Spam is a junk e-mail which causes violent and needless disturbance on system and storage space and carry the virus, so ethical hacking helps to reveal such attacks against in computer systems and provides the security of the system. The main application of this is to provide the security on wireless infrastructure which is the main purpose of present business organization (BT, 2008). Ethical hacking has become main stream in organizations which are wishing to test their intellectual and technical courage against the underworld. Ethical hacking plays important role in providing security. Resources are the computer related services that performs the tasks on behalf of user. In Ethical hacking the resources are the core services, objects code etc (James Tiller S, 2005). The ethical hacking has advantages of gaining access to an organizations network and information systems. This provides the security in the area of Information technology called as Infosec. This provides security to the high level attacks such as viruses and traffic trough a firewall. This has been providing the security for various applications which are even bypassing the firewalls, Intrusion-detection systems and antivirus software. This includes hacking specific applications including coverage of e-mails systems, instant messaging and VOIP (voice over IP). The resources i.e. devices, systems, and applications that are generally used while performing the ha cking process are Routers, Firewalls, Network infrastructure as a whole, wireless access points and bridges, web application and database servers, E-mail and file servers, workstations, laptops and tablet PCs, Mobile devices, client and server operating systems, client and server applications (Kevin Beaver, 2007). Ethical hacking tests both the safety and the security issues of the programs (Ashoke Talukder K and Manish Chaitanya, 2008). Hence from the above context it can be stated as the ethical hacking is important in the present scenario as providing security is very important now a day. This is very important in web applications as the hacking can be easily done in this case. Problems Ethical hacking is the backbone of network security. The basic problems with this is trustworthiness of the Ethical hacker because lets take an example if a person has been appointed to do Ethical hacking, to provide security for the bank financial issues if the person is not trust to believe this is not safe as the person only considered as thief. Sometimes the big organizations face any problem like there passwords has been hack, this case hiring professionals is very expensive and the organization need to spend a lot on this (Ethical Hacking, 2009). Ethical hacking is just the security to the problem it is not the ultimate solution to it. Ethical hacking report must be kept confidential because they highlight the organizations security risks and attacks. If this document has been falls into the wrong hand the result would be very disastrous for the organization, the main drawback here is the entire information of the organization will be in hands of wrong person and which leads to the loss of the company (Kimberly Graves, 2007). Ethical hacking generally involves breaking down the computer applications and by collecting specific information from the target the ethical hacker can successful to access the information and can reveal it. This results in that highly sensitive information about the targets security capabilities is collected and maintained far away from the owners control. If this information fall into wrong hands results in real attack on the company and another problem is if the information is leaked to the public or stockholders, the business will be in risk, which results in all types of disasters, including negative character by media, loss of customers and legal consequences (James Tiller S, 2005). Ethical hacking use tools while it performing the activity, if the methods and tools are used incorrectly they cause damage (Dr. Bruce Hartly V, 2003). Hence from the above context it can be stated as Ethical hacking provides security but behind th at it provides the disadvantages like the Ethical hacker should be trusted by the organization or business and in case sometimes highly professionals may cost the organization very much so that company has to provide from the unplanned budget and if it goes into the wrong persons hand the business will be in danger and loss of the organization will takes place. Chapter 3: Research Methodology of Hacking Data types: Data type is defined as the format of a data storage which is used to store different set of values. It tells about which type of data to be stored and where to be stored. Data is stored in computer memory. There are two types of data. They are primary data and secondary data. Both primary and secondary data illustrates the gathering of information and to satisfy the goals of business. Primary data is nothing but it is the data which is collected newly and for the first time. The primary data is original. It is the fresh data and is never gathered before. Secondary data is the data which is collected by others (Norman Blaikie, 2009). The data is collected from newspapers, magazines and journals. Secondary data is gathered before primary data since it is time consuming. Data is gathered newly in case of primary data so it takes much time. Secondary data consumes less time. Primary data is used in ethical hacking since the data gathered in this type of data is very efficient. Ethical h acking is used legally for the official purposes. Since primary data is unique and is not compared with any one, it is used in the process of ethical hacking (Rajat Khare, 2006) Hence from the above context it can be said that data types are useful in the ethical hacking. Case study: According to media and people the word hacking denotes misuse and collapse of computers. They describe it as unfair method of solving the problem. In the view of ethical hackers the word hacking refers to creative. One of the organization namely Amazon, it is not proposed to point out the lesser features but deals with tricks for working the company efficiently. Hackers and developers will create new characteristics for Amazon. They bring out the creative thinking and innovative ideas by their work in company (Paul Bausch, 2003). Mainly the ethical hacking is the good way to improve the existing methods and qualities. Many organizations follow these because one can know the administrative password of employees, can reach the behaviour of them and working performance. Employee performance and his project carryout can be studied through ethical hacking. These hackings look easy for them since they are engaged with the security firms to protect the Amazon fields. Not only in Amazon in e ach and every organization is this steps fol

Physics of the Acoustic Guitar Essays -- physics guitars

Stringed instruments are most likely the oldest type of musical instruments. The acoustic guitar has been around since the 1500's, and is the most common stringed instrument used today. The guitar is one of the most versatile instruments in existence, being used in virtually every style of music. It can produce a wide range of sounds depending upon the style of the guitar and the type of strings used on it. The two main styles of acoustic guitars are the nylon-stringed and the steel-stringed. Nylon-stringed guitars are used mainly for styles such as classical music and flamenco. Steel-stringed guitars are most commonly associated with country and folk music. Before getting into how the guitar works, it will be beneficial to take a look at the different parts that make up a guitar. A guitar has three main parts- a body, neck and headstock. There are various styles and designs for acoustic guitars, but no matter the style, all of them have essentially the same parts. The body acts as an anchor for the neck and bridge. The top of the body is called the sounding board. It is responsible for almost all of the guitars acoustics, and is what allows the ear to hear the sound created by playing the guitar. The sounding board generally has a large hole cut in it called the sound hole. The bridge, which is also located on the sounding board, is what anchors the strings to the body. The neck is the long, slender part of the guitar connecting the body to the head. the front of the neck is called the fret board. This is where the frets are spaced down the entire neck. The frets are thin bars that are set perpendicular to the strings. The frets make it possible to create a variety of tones by... ... pattern of these resonance waves in order to cut down on interference, thus creating a richer sound. Bibliography Askill, John.

Nylon-stringed guitars are used mainly for styles such as classical music and flamenco. Steel-stringed guitars are most commonly associated with country and folk music. Before getting into how the guitar works, it will be beneficial to take a look at the different parts that make up a guitar. A guitar has three main parts- a body, neck and headstock. There are various styles and designs for acoustic guitars, but no matter the style, all of them have essentially the same parts. The body acts as an anchor for the neck and bridge. The top of the body is called the sounding board. It is responsible for almost all of the guitars acoustics, and is what allows the ear to hear the sound created by playing the guitar. The sounding board generally has a large hole cut in it called the sound hole. The bridge, which is also located on the sounding board, is what anchors the strings to the body. The neck is the long, slender part of the guitar connecting the body to the head. the front of the neck is called the fret board. This is where the frets are spaced down the entire neck. The frets are thin bars that are set perpendicular to the strings. The frets make it possible to create a variety of tones by... ... pattern of these resonance waves in order to cut down on interference, thus creating a richer sound. Bibliography Askill, John.

Virus and Bacteria

A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria – Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as large as the tiniest bacteria.Viruses are microscopic; they range in size from about 20 to 400 nanometers in diameter (1 nanometer = 10-9 meters). By contrast, the smallest bacteria are about 400 nanometres in size. o Another difference is their structure. Bacteria are complex compared to viruses. A typical bacterium has a rigid cell wall and a thin, rubbery cell membrane surrounding the fluid, or cytoplasm inside the cell. A bacterium contains all of the genetic information needed to make copies of itself—its DNAâ €”in a structure called a chromosome. In addition, it may have extra loose bits of DNA called plasmids floating in the cytoplasm.Bacteria also have ribosomes, tools necessary for copying DNA so bacteria can reproduce. Some have threadlike structures called flagella that they use to move. o A virus may or may not have an outermost spiky layer called the envelope. All viruses have a protein coat and a core of genetic material, either DNA or RNA. The main difference between viruses and bacteria is the way they reproduce. Bacteria, given the proper nutrients, can grow and reproduce on their own. But viruses cannot â€Å"live† or reproduce without getting inside some living cell, whether it's a plant, animal, or bacteria.Viral vs. Bacterial Reproduction Bacteria contain the genetic blueprint (DNA) and all the tools (ribosomes, proteins, etc. ) they need to reproduce themselves. Viruses are moochers. They contain only a limited genetic blueprint and they don't have the necessar y building tools. They have to invade other cells and hijack their cellular machinery to reproduce. Viruses invade by attaching to a cell and injecting their genes or by being swallowed up by the cell. Here's an example of viral infection. These are T4 bacteriophages. They are a kind of virus that infects bacteria.Here they are landing on the surface of an E. coli bacterium. The bacteriophage cuts a hole in the E. coli's cell wall. It then injects its genetic material into the bacterium. By taking over the E. coli's genetic machinery, the viral genes tell the bacterium to begin making new virus parts. These parts come together to make whole new viruses inside the bacterium. Eventually so many new viruses are made that the E. coli bursts open and dies, releasing all those new viruses to infect more cells! Some diseases caused by virus and bacteria:Name of the disease |Caused by |Name of the microbes | |Polio |Virus |polio | |Pneumonia |Virus / Bacteria |influenza virus (flu) | | | |r espiratory syncytial virus (RSV) | |Hepatitis |Virus |Hepatitis A Virus | | | |Hepatitis B Virus | |Mumps |Virus | | |Bronchitis |Virus |respiratory syncytial virus (RSV) | |AIDS |Virus |human immunodeficiency virus(HIV) | |Tuberculosis |Bacteria |Mycobacterium tuberculosis | |Tetanus |Bacteria |Clostridium tetani | |Anthrax |Bacteria | | |Diphtheria |Bacteria | | |Chicken Pox |Virus |varicella-zoster (VZV) |How bacteria and viruses enter the body To cause disease bacteria have to gain access to the body.The ways in which a bacteria can get access to an animal body are:†¢ Cuts†¢ Contaminated food or water†¢ Close contact with an infected person†¢ Contact with the faces of an infected person†¢ Breathing in the exhaled droplets when an infected person coughs or sneezes†¢ Indirectly, by touching contaminated surfaces – such as taps, toilet handles, toys and nappies.Viruses are spread from one person to another by:†¢ Coughs†¢ Sneezes†¢ Vomits†¢ Bites from infected animals or insects†¢ Exposure to infected bodily fluidsCuring a bacterial infection The body reacts to pathogenic bacteria by increasing local blood flow (inflammation) and sending in cells from the immune system to attack and destroy the bacteria.Antibodies produced by the immune system attach to the bacteria and help in their destruction. Serious infections can be treated with antibiotics, which work by disrupting the bacterium's metabolic processes. The body's response to viral infection Viruses pose a considerable challenge to the body's immune system because they hide inside cells. This makes it difficult for antibodies to reach them. However, special immune system cells, called T-lymphocytes, can recognize and kill cells containing viruses. Many viruses, when released from infected cells, will be effectively knocked out by antibodies, produced in response to infection or previous immunization.Antibiotics are useless against viral infecti ons. Antiviral drugs are available only for few viral diseases, such as influenza, herpes, hepatitis B and C and HIV, but research is ongoing. However, immunization is helpful in fighting viral infection. The large scale immunization has led to the eradication of small pox once one of the most feared viral disease. How to Know When You Need Antibiotics Don't expect antibiotics to cure every illness. Antibiotics are only effective against bacterial infections. In the past antibiotics were prescribed â€Å"just in case† the infection was bacterial rather than viral because it was thought that taking them â€Å"couldn't do any harm†. Wrong.This very practice has contributed to the development of antibiotic resistant strains of bacteria. While the use of antibiotics depends on the specific diagnosis, basic guidelines include: Colds and flu are caused by viruses. They can’t' be cured with antibiotics. Symptoms can last two weeks or more and should be allowed to run t heir course.Cough and bronchitis are almost always caused by viruses. However, if you have a lung condition or the illness lasts a long time; your infection may be caused by a bacteria instead. Your doctor may decide to try treatment with an antibiotic.Sore throats are most often caused by viruses. Strep throat is caused by bacteria and requires treatment with antibiotics. A throat swab and a lab test are needed before your doctor will prescribe an antibiotic for a sore throat.Ear infections often require the use of antibiotics. However, not all ear infections are bacterial infections.Sinus infections do not always indicate a bacterial infection.Even if you have a runny nose, or yellow or green mucus, you may not have a bacterial infection. Antibiotics should only be used for severe infections or infections that last more than two weeks. What is diarrhea? Diarrhea can be caused by a variety of bacteria, viruses, and parasites. Children can also have diarrhea without having an infect ion, such as when diarrhea is caused by food allergies or as a result of taking medications (such as antibiotics).A child is considered to have diarrhea when the child's bowel movements are both more frequent than usual and looser and more watery than usual. Children with diarrhea may have additional symptoms including nausea, vomiting, stomach aches, headache, or fever. Swine Flu: Swine flu is an infection caused by a virus. It's named for a virus that pigs can get. People do not normally get swine flu, but human infections can and do happen. The virus is contagious and can spread from human to human. Symptoms of swine flu in people are similar to the symptoms of regular human flu and include fever, sore throat, muscle pains, severe headache, coughing, chills, weakness and general discomfort.Figure: Electron microscope image of the reassorted H1N1 influenza virus photographed at the CDC Influenza Laboratory. The viruses are 80–120  nanometres in diameter. There are antivir al medicines you can take to prevent or treat swine flu. There is no vaccine available right now to protect against swine flu. You can help prevent the spread of germs that cause respiratory illnesses like influenza byCovering your nose and mouth with a tissue when you cough or sneeze. Throw the tissue in the trash after you use it.Washing your hands often with soap and water, especially after you cough or sneeze. You can also use alcohol-based hand cleaners.Avoiding touching your eyes, nose or mouth. Germs spread this way. Trying to avoid close contact with sick people.Staying home from work or school if you are sick. Prevention of food to contaminate Here are four major tips recommended by the Centers for Disease Control and Prevention (CDCP) to prevent contaminating food.Use caution when buying food. o When at the grocery store, pick up perishable food such as meat, eggs, and milk at the very end of your shopping, so they will stay cool. o Take food home right away so that it doe s not spoil in a hot car. o Avoid raw or unpasteurized milk. o Because eggs, meat, seafood, and poultry are most likely to contain bacteria, do not allow their juices to drip on other food.Store food properly. Store eggs, raw meat, poultry, and seafood in the refrigerator. o A refrigerator should be set at 40 ° F. o A freezer should be set at 0 ° F. o Regularly clean and disinfect the refrigerator and freezer. o Use containers to prevent contaminating other foods or kitchen surfaces. Do not store food uncovered in the refrigerator or freezer.Use special precautions when preparing and cooking food. o Wash your hands and clean and disinfect kitchen surfaces before, during, and after handling, cooking, and serving food. o Defrost frozen food on a plate either in the refrigerator or in a microwave, but not on the counter. o Cook food immediately after defrosting.Use different dishes and utensils for raw foods than you use for cooked foods. o Wash raw fruits and vegetables before eat ing them.Cool and promptly store leftovers after food has been served. o Because harmful bacteria grow at room temperature, keep hot food hot at 140 ° F or higher, and keep cold food cold at 40 ° F or cooler. This is especially important during picnics and buffets. o Do not leave perishable foods out for more than two hours. o Promptly refrigerate or freeze leftovers in shallow containers or wrapped tightly in bags.Figure: (a) Components of virus, (b) components of bacteriaFigure: Reproduction of T4 bacteriophage Virus

Hydraulic Fracturing

Is hydrologic fracturing a suitable form of energy production? Over the past 85 years, the American Petroleum Institute, API, has been developing and refining engineering standards and practices for the industry. The past decade has brought about a new practice which involves hydraulic fracturing in order to produce oil and natural gas in places where conventional technologies are ineffective. This is a rather in depth process. Firstly, a production drill is drilled through the rock layers to intersect the coal seem that contains coal bed methane, CBM. Next, fractures are created or existing fractures are enlarged in the coal seem so that the CBM can be drawn from the well and pumped to the surface. These fractures are created or enlarged by using a thick water-based fluid which is gradually increased by rate and pressure. Then, over time the coal seam is unable to keep up with the fracturing fluid which results in high pressure causing the coal to fracture along the weaknesses within. Sand is pumped into these fractures to keep them ‘propped’ open after the pressures are released. The first diagram in the appendix shows what occurs in the subsurface during a typical hydraulic fracturing event. After a period of fluid recovery or groundwater extraction is when the extraction of CBM occurs. As pumping continues, the pressure eventually decreases so that the methane desorbs from the coal, flows and is extracted through the production well. The fracture created acts as a conduit in the rock or coal formation, allowing the CBM to flow more freely from the coal seems through the fracture system and to the production where gas is pumped to the surface. Unlike conventional gas production, the amount of water extracted declines proportionally with increasing CBM production (US EPA, 2004). The demand of natural gas is expected to increase drastically over the next 20 years, causing the need for innovative production to fill the growing demand. Many may believe that there are other ways to fulfill the need of natural gas, due to production concerns, but this is a suitable form of energy production. Hydraulic fracturing should be used because it will provide a significant increase in jobs, economic growth, and clean burning energy. The Keystone XL pipeline has had much controversy in the news recently. This pipeline is an extension onto the existing pipeline running from Canada to the United States. The pipeline would increase crude oil capacity between the two countries allowing for a more diverse supply among the United States’ worldwide crude oil sources, shorten the transportation pathway for crude oil supplies, and increase the crude oil supplies from a major non-organization of petroleum exporting countries producer. â€Å"The use of hydraulic fracturing will help make our country more energy self-reliant and more secure† (Green, 2012). This statement was made by the API President and CEO, Jack Gerard during the second State of American Energy event January 4. He also proceeded to state that the United State’s resources on and offshore are among the largest in the world. This means that with the right policies in place, there could be 100 percent of our liquid fuel needs supplied domestically and from Canada by 2026. Also, with a pro-energy development approach 1 million new US jobs by 2018 could be produced along with billions of dollars in additional revenue to government (Green, 2012). The increase in jobs from this production is approximately 334,000 in the past two years after the 3 million manufacturing jobs lost from 2001-2007. Hydraulic fracturing has rapidly increased the domestic production of natural gas and has seen low domestic prices for households. Figure five below shows the increase in production rates over the last several years (Green, 2012). The oppositions to this vision are primarily political on an ecological level. In order for the process to run smoothly water use is needed. Many think that the water used for hydraulic fracturing could deplete fresh water supplies and impact aquatic habitat. Some also say that the groundwater could be contaminated. Some hydraulic fracturing fluids can also contain chemicals. Typically a mixture of water, proppants and chemicals are what is pumped into the rock or coal to fracture the wells. Eco-friendly leaders and environmentalists are taking a stand to state that these chemicals, use of water and damage to groundwater are not acceptable and this energy method should not be used. Firstly, chemicals typically make up just 0. and 2% of the total volume of the fracturing fluid with the majority being water. Secondly, natural gas emits fewer greenhouse gases than other fossil fuels, about half as much of carbon dioxide as coal which contributes to less global warming. Thirdly, with the halting of fracturing in some states due to pressures from environmental and public health groups asking the EPA for tests and proof that it is safe to continue with this type of energy production, supporters are concerned that it could hinder U. S. job growth and energy output in a time of need (McLendon, 2010). The tests from the EPA will take roughly two years, so until then it is a waiting process. As you can see, this is a roughly new energy production that does need to be researched more. From my point of view the pros seem to outweigh the cons. I think more tests and actual data about contamination and whether it is really safe will be the true test. The increase in jobs, economic growth, and clean burning energy is most definitely what this country needs right now. The true outlook on this issue will come towards the later part of this year when the test results conclude. References Green, M. (2012, January 05). Starting the energy debate.
