Change Management in the Learning Organization Essay Example for Free
Change Management in the Learning Organization Essay In this paper I intend to discuss change management approaches that support the learning organization philosophy. The learning organization is defined as an organization that acquires knowledge and innovates fast enough to survive and thrive in a rapidly changing environment. Learning organizations (1) create a culture that encourages and supports continuous employee learning, critical thinking, and risk taking with new ideas, (2) allow mistakes, and value employee contributions, (3) learn from experience and experiment, and (4) disseminate the new knowledge throughout the organization for incorporation into day-to-day activities. On the other hand we have a process called change management which is defined as minimizing resistance to organizational change through involvement of key players and stakeholders. At my organization these two go hand in hand and it allows for us as a company to experience constant growth and development of our staff. Our employees are more willing to welcome change when we train them in the process. As businesses moves through the 21st century, they are becoming more dependent upon their managers to be change agents. These companies actually seek managers who can bring success to their organizations. Three of the characteristics we look for in our new managers are they must have the ability to stimulate change, excellent planning capabilities, and ethics. Over the years I have spent in management I have learned that success inà becoming a learning organization relies on a commitment to learning on the part of the organizations I have worked for and the willingness of the individuals involved to be receptive to the change process. As a manager, what we usually can change falls into basically three categories; people, structure, or technology. An efficient manager will make alterations in these areas in an attempt to facilitate change. With people the change involves adjusting attitudes, expectations, perceptions, and probably most importantly behavior. Coaching people to adjust in these areas will help employees within the organization to work together more effectively. Changing structure relates to the job design, specialization, hierarchy and any other structural variables. These usually need to be flexible and non-static in order to be adaptable to change. When dealing with technological change we are looking at modifying work processes and methods along with the introduction of new equipment. To me learning organizations support the change process just as much as change management supports the learning organization philosophy. I say that because every change calls for some sort of learning as the more comprehensive the change the more attention we have to place on learning for the individuals involved in the change. By utilizing the learning organizations philosophies companies including the one I work for are able to magnify the potential of its employees which keeps them growing.

Samuel Beckettââ¬â¢s Waiting For Godot and The Theater of The Absurd Essay
With the appearance of Waiting for Godot at the Thà ©Ã ¢tre de Babylone in Paris in 1953, the literary world was shaken by the arrival of a drama so different yet so thrilling that it gave rise to the "Theater of the Absurd". His contribution to this particular type of theater movement allows us to refer to him as the father of the genre. While other dramatists, such as Tom Stoppard, have also contributed to this genre, Beckett remains its single, most lofty figure. It is this type of theater that deals with the absurd aspects of life, to stress upon its native meaninglessness. It is the time and identity of characters that are usually vague or ambiguous in such plays from the theater of absurd. The plays are dreamy and impossible to implement in real life and the dialogues of such plays are irrational and make the play seem absurd because the whole structure of the play is in repetition. In this play, Samuel Beckett emphasizes upon human suffering. The play revolves primarily around Estragon and Vladimir who endlessly wait for something to help overcome their boredom and sins because they seek redemption as mentioned in the play. Godot can be assumed as one of the many wishes that Vladimir and Estragon wait for. Waiting for Godot is part of the ââ¬ËTheater of the Absurdââ¬â¢. This implies that it is meant to be irrational and pointless in nature since you do not have a proper moral and conclusion to the play, i.e., it is an open ended play. The readers and audiences can have many conclusions towards the end of the play. The concepts of drama, chronological plot, logical language, themes, and recognizable settings are features of drama that a play from the Theatre of Absurd does not have. We see how the characters of Vladimir and Estrago... ...s with their incoherent colloquy. And above than all, its theme is unexplained meaning that the play does not only have a single theme like adventure or action. ââ¬Å"Waiting for Godotâ⬠is an absurd play for it is devoid of characterization and motivation. Though characters are present but are not recognizable for whatever they do and whatever they present is purposeless. Works Cited Beckett, Samuel. Waiting For Godot. 3rd ed. N.p.: CPI Group, 2006.

Itgs Exam Questions and Full Mark Answers
ITGS Homework Area of impact- Science and the environment A) Identify two input devices that are required in order for Jules to interact with a real person. There is several input devices required in order for Jules to interact with a real person, these include a microphone, a web cam or digital camera, normal camera and speakers so the person can hear Jules. B) Describe the steps that Jules would take in order to follow the movement of the person talking to him. There are several steps that Joules would take to interact with a real person. . Jules could capture the initial image of any human being using its camera or webcam sensors to capture an image. 2. Jules would have to use facial recognitions software to determine the parts of the face to face tracked (reference points) or identify different parts of the face such as skin colour or your eyes. Laptops these days also have sensors built into them. 3. Record an initial position; of the face which is to be tracked/ set the positio n of the human in relation to the robots own position. 4. Recording of time lapse intervals 5.Capture images at new positions 6. Determine the location of the new position 7. If there is no movement, then no movement is detected and there is no adjustment. 8. Jules can adjust to the movement if there is one 9. Jules can now communicate with the human being 10. So this process can be repeated. C) Jules may have difficulty understanding a sentence in a conversation with a human, explain why this could happen. If a word that is said that is not in the language database of the robot the sentence that is said by the human will not be comprehended by the robot.Unusual grammar and sentence structure that is not programmed in Jules language database will cause difficulties. Jules may understand only one type of accent and may struggle to communicate if Jules communicates with someone with a different accent. Colloquial expression was used. Unclear speech due to unclear conversion of human s ound converted to digital sound files which cannot be matched will cause Jules to not understand the human being. Background noises can cause Jules to misinterpret human voices. Linguistic differences- Words may have different meanings depending on the context.D) Evaluate whether the organizers should go ahead with this decision to replace human umpires with robotic umpires such as tennis-umpire There are several positives and negatives of this. Positives include 1. The robot would consistently determine the outcome of each play, so human reaction is not present. So reviews wonââ¬â¢t be needed. 2. Any robot will not ever get tires or struggle due to physical conditions. (Reactions of crowd, weather). 3. There is no chance that a robot will be biased towards another player, something that can be present when a human referee is officiating.So they donââ¬â¢t care who win. Robots are more likely to make the right calls first time so this will save time from reviews. 4. Another pos itive is that robots will not face pressures of the crowd when making a decision because they feel no pressure due to their lack of emotions. Negatives include. 1. Even though robots may be accurate, because of the quick movement of the ball, it may take time for the robot to make the decision; this will make games go a lot slower. 2. Players may block the view of the ball or other obstacles which the robot will find impossible to avoid. . There are ethical issues present as well because the robots can actually replace human umpires if several of them are present within a game. 4. Cost maintenance of robots are very high, example are a lot harder/ more expensive to maintain than human umpires. 5. Players and the crowed might react negatively to robot umpires as they have never been used before. 6. Robot umpires are not designed to argue with players so if any supporter or player disagrees with the ref even with their accuracy what happens then? 7.Robots will not be able to detect an y misconduct any player does during the match, something that humans are capable to do because robots do not understand human emotions. 8. Robots arenââ¬â¢t programmed to do the unexpected so anything that happens not regarding to tennis for example a fan interrupting the game by running onto the court, robots will not be able to do anything about or they might hurt the fan that runs onto the court. 9. If letââ¬â¢s say a player wasnââ¬â¢t ready for the ball, a human umpire could call a replay. This is something a Robot cannot interpret.

Network Security Problems Analysis Essay
Network Security Problems Analysis Essay Network Intrusion Analysis Essay Example Network Intrusion Analysis Essay Example The problem of selection of reliable data sources for the process of digital forensics investigation is particularly relevant nowadays, with each type of computer-related crime relying on a specific set of such sources. In particular, in the case of network intrusion, user accounts, operation and intrusion detection systems, as well as the logs of Internet providers are the most useful sources of information. For malware installation, the investigators are likely to find the evidence that they require by analyzing system data, the storage of intrusion detection system, and the information provided by a virtual machine. Finally, in the case of insider file deletion, the investigation has to rely on hard disks and network storages as the primary sources of useful data. Common Network Security Problems Computer-related crimes are among the consequences of mass computerization of the society. The integration of modern information technologies in almost all areas of human activity has led to the fact that many traditional crimes (e.g. appropriation, theft, fraud, counterfeiting, etc.) are being committed with the help of computers. Crimes associated with the use of computer technology present a serious threat to any company or individual. In order to identify the offenders responsible for this damage, a special procedure called digital forensics investigation is conducted. On the contrary to the usual process that involves the gathering of evidence by questioning the witnesses, it relies on the information obtained from the digital sources. However, the quality and reliability of the gathered data may vary depending on the situation, which may affect the course of the investigation. As a result, the problem of selection of data sources for solving a computer-related crime becomes esp ecially relevant. Therefore, the following research focuses on identification of the most valuable data sources that can be used in different cases of computer-related crimes (network intrusion, malware installation, and insider file deletion). Additionally, it classifies them in terms of their usefulness to investigators. The network intrusion is the process of unauthorized access to the network that is mostly conducted with a malicious intent. The risks of such an activity are related to the devastating effects of the loss of time and money as a result of damage or theft of the important information and resources. The attackers can gain access to the network by exploiting vulnerabilities in software, hardware, or even attack by using such refined techniques as guessing other usersââ¬â¢ logins and passwords. An attacker that gains access to the network becomes the source of the four following types of threats: Data theft; Identity theft; Data loss and data manipulation; Termination of service. In case of such an event, it is possible to distinguish several data sources that are of the most significant value for the digital forensics investigation. They include user accounts, the operation system itself, the intrusion detection system, and the records kept by the providers of web services. User Accounts The user accounts provide the most valuable information for the digital forensics investigation. In particular, the security measures of the majority of private networks involve the use of complex passwords that are to be changed regularly, the constant update of the list of registered users, and the limited amount of the incorrect attempts to enter the system. As a result, the possibility of the intrusion is lowered since it is impossible to log in to the network by using a fake account. Still, in case such an event has occurred, the audit of the existing user accounts may allow to identify the source of the intrusion, i.e., a particular account used by the attacker, thus narrowing the field of search. In turn, this information may provide investigators with hints regarding the ways of obtaining access to network, the timeline of the event, i.e., the time of logging in and out, the ways of misusing the account data, and so on. In other words, this data source defines the direction o f the entire process of investigation (Fichera Bolt, 2013). As a result, in terms of network intrusion, user accounts and the results of their audit are the most valuable of the listed sources of information. Operation System The information that is collected from the operation system, i.e., live system data, is also of high value for the digital forensics investigation. By reviewing it, it is possible to define the following details of the intrusion. First of all, the analysis of the system logs may provide the information on the password that the attacker used to access the network. In turn, this allows to define whether the user account was hacked or the password to it was simply stolen. Next, the analysis of system data may give insight into the nature of manipulations performed by the attacker within the network. In particular, the criminal may pursue specific goals by obtaining access to it. For example, in the case of a single event of data theft, the system logs are likely to contain the information on copying certain files. On the other hand, in case the offenderââ¬â¢s primary goal was data manipulation or termination of the system (the events that usually require several intrusions), it is li kely that certain software will be altered or replaced to utilize the weaknesses of the system and simplify the consequent intrusions. For example, the attacker may replace the original application layer protocol with a modified one that allows remote access to the system, which means that the intrusions will be occurring on a regular basis (Casey, 2010). As a result, the information on the nature of manipulations within the system may help define the motives of the crime, thus simplifying the process of identification of the attacker. All these facts allow to rank the aspect of system data second in the list of the most valuable sources for the digital forensics investigation. Indeed, its analysis allows to discover the files and systems that were altered as a result of intrusion, as well as define the way used by the attacker to access the network. Intrusion Detection System Intrusion Detection System (IDS) is a hardware or software designed to detect the facts of unauthorized access to a computer system or network or their unauthorized management. IDS provides an additional level of security of computer systems by alerting the administrators of any abnormalities in the work of the network. The typical IDS includes a sensor subsystem for collecting the events related to the security of the protected system, analytical subsystem designed to detect attacks and suspicious activity on the basis of sensor data, and storage providing the accumulation of primary events and analysis. In most cases, the analysis preformed by IDS is based on the principle of signature matching: the system refers to the dictionary of the known attack signatures. In case any part of the attack pattern complies with the existing signature, the system makes an attempt to halt it and warns the administrator of a threat. However, in order to achieve the maximum efficiency of this method , it is necessary to replenish the dictionary of the signatures on a regular basis. At the same time, the attack patterns used by the offenders are becoming more sophisticated, meaning that even the newest signatures cannot guarantee complete protection of the network. In turn, this results in an increased amount of false alarms on the part of IDS (Casey, 2010). Still, the data from the storage of IDS, namely the alarms, can be useful for investigation, provided it is sorted. By filtering all the false alarms, it is possible to use the remaining information for the analysis of the less developed system logs and search for the clues on the nature of the attack. In particular, the use of IDS data makes it possible to obtain additional details about the connection used by the attacker and thus prevent the consequent attempts of intrusion. In some cases, it also allows to pinpoint the direction of the traffic, thus simplifying the process of identification of the attacker. However, such an analysis requires comprehensive knowledge of operation systems and hacking techniques, as well as the presence of logs of diagnostic tools. As a result, IDS can be placed on the third place in terms of its value to the digital forensics investigation of network intrusion: it provides useful information that may affect the course of investigation significantly, but its identification and isolation from the pool of unnecessary data requires great efforts on the part of investigators. The Records of the Providers of Web Services In order to organize and conduct their attacks on networks, the offenders must use web services (the Internet connection, messengers, etc.). As a result, by turning to the providers of these services, it is possible to acquire the information on the timeline of their use by the hackers at the time of event. Nevertheless, providers may collect such data as names and e-mail addresses of their clients as well as their payment information, e.g. data on credit cards and bank accounts. In the case of Internet providers, it is also possible to obtain IP addresses of the potential offenders at the time of the event, in case the dynamic IP is used. All this information can be employed to prove either involvement or non-involvement of the potential offenders in the act of network intrusion. However, each of the providers has a different policy regarding the consumersââ¬â¢ data collection, meaning that it is difficult to obtain consistent information in this way. Moreover, there is no guaran tee that the obtained information is reliable. As a result, the records of the providers of web services are ranked fourth and last in terms of their value to the digital forensics investigation. Malware Installation Malware is any software designed to gain unauthorized access to the resources of the computer or network. Currently, there are tens of thousands of such programs, with the new ones being created on a regular basis. Malware may cause serious damage to corporate networks, email systems, and web sites by using their different vulnerabilities. Its installation may result in the following negative effects: The interference to the processes of the infected system (the block of antivirus software and administrative functions of the operating system as well as the sabotage of the computer-controlled processes); The installation of another malicious software (either by downloading it from the network or unpacking another malicious program already contained within the file); Theft, fraud, extortion, and spying on the user (theft of accounts of various services and payment systems as well as key logging); Other illegal activities (an unauthorized access to the resources of the computer, the organization of DDoS-attacks, etc.) (Sikorski Honig, 2012). In the case of malware installation, such data sources as the operation system itself, IDS, and virtual machine are of the highest usefulness for the digital forensics investigation. Operation System The volatile data collected from the running operation system, specifically the one obtained at the time of malware installation, allows to conduct a search for hidden files that were integrated into the system by malware. In this regard, the alternate data streams present the highest value for investigators. Moreover, the analysis of such components of the system as drivers and applications as well as the executed services and processes may help identify the type of malware and its source (Sikorski Honig, 2012). The usefulness of this data becomes even higher in case investigators were able to discover the fact of malware installation before it was finished. The primary reason for that is the fact that they may collect and analyze the data on it without alerting the criminal. As a result, the process of identification of the offender is simplified. At the same time, the discovery of the fact of malware installation often requires a comprehensive analysis of the potentially infected system. As was mentioned before, new types of malware are being developed regularly, meaning that even the use of the most advanced diagnostic tools does not guarantee the absence of false alarms or critical failures, for example, the malware is not detected until it causes irreparable damage to the system (Casey, 2010). Nevertheless, all the above mentioned facts allow to consider the operating system as the most valuable source of information for the digital forensics investigation of the malware installation case. Intrusion Detection System As was mentioned before, IDS identifies and blocks threats, including malware, on the basis of signature matching principles. As a result, the data obtained from its storage may be used to identify the type of malware as well as the attack pattern used by the offender. Moreover, after obtaining the volatile data collected from the running operation system, it is possible to compare it with the existing signatures in the dictionary of IDS and define whether the installed malware has any specific features, for example, downloader, dropper, etc. (Sikorski Honig, 2012). In turn, this information may provide evidence on the goals of the attacker. At the same time, there is no guarantee that the log of IDS will be free of false alarms or that the system will detect the attempt to install malware. Moreover, comparing signatures and volatile data, the amount of information may be overwhelming, which may slow the process of investigation (Marshall, 2008). Considering the mentioned issues as well as the fact that IDS can be used to its full extent only after the analysis of the volatile system data, it is possible to rank it as the second useful source of information for the digital forensics investigation of the malware installation case. Virtual Machine In the case of malware installation, investigators often have to examine the principles of operation of the harmful software and determine the potential threat that it contains by using a virtual machine. It is a software and/or hardware system that emulates the hardware of a target platform and executes the programs for a target platform on the host platform. It can also virtualize a particular platform and create the environments that isolate programs and even operating systems from each other on its basis (Barrett Kipper, 2010). The virtual machine allows to examine the behavior of malware in different conditions and gives an opportunity to return to any stage of the malware installation process as well as change its pace. In turn, it may provide evidence on the type of files that the program tries to modify or delete, the information that it tries to collect as well as the final destination of the stolen data (Sikorski Honig, 2012). As a result, it may provide insight either in to the motives of the attacker or his location, thus speeding the process of investigation. At the same time, the virtual machine cannot always act as a perfect replica of an operating system. As a result, the likelihood of it being discovered by the attackers increases, meaning that they will take safety measures, thus slowing the process of investigation. Moreover, it may not always provide a sufficient environment for the analysis (Barrett Kipper, 2010). Considering all these facts, it is possible to rank it third in the list of the most useful data sources for the digital forensics investigation of the malware installation case. Insider File Deletion Insider file deletion is a threat that emanates from the people within the organization, such as its current and former employees, contractors, and business partners that have information on security practices within it as well as the data and computer systems. Insiders may have passwords that give them legal access to the system. Moreover, they are often familiar with the data and intellectual property of the organization as well as the methods used to protect them. As a result, they can circumvent the entire security system. Physical proximity to the data means that insiders do not need to break through the organizational network by passing the outer perimeter firewalls. Due to the fact that they often have a legitimate access to the information, the file deletion performed by the insiders is difficult to track and prevent (Probst et al., 2010). In this case, such data sources as hard disk drives and network storages are most useful for the digital forensics investigation. Hard Disk Drive Considering that the insider file deletion is usually aimed at non-volatile data, which is not deleted after the shutdown of the system, it is clear that the hard disk drive will be the primary target of the attackers. Despite the fact that the file has been removed completely, i.e., deleted from recycle.bin, only the information regarding its storage sector, path, and create/modify date is erased from the system drive. By using the forensic software, it is possible to recover it, thus nullifying the damage done by the insider and, which is most important, obtaining the evidence on the motives and time of the crime, namely by reviewing the contents of the target file and the time of the deletion (Marshall, 2008). At the same time, the recovery is possible only within a short period of time since the required file data can be overwritten by the system. Moreover, the insider may use specific software to overwrite the mentioned data immediately, meaning it cannot be recovered (Probst et al., 2010). Nevertheless, due to its nature of a primary target, a hard disk drive is the most useful data source for the digital forensics investigation. Network Storage The network storage can be used as a data source in case the deleted file was previously shared with other users. In general, the algorithm of its recovery is based on the search of previous versions of this file. The information obtained from it serves similar purposes. However, in case of network storage, the challenges faced by investigators are more significant due to the overwhelming amounts of information in comparison to that stored on the hard disk drive. Moreover, as in the previous case, the insiders may delete the file permanently or erase the parts of network storage that contain the corresponding information (Lillard et al., 2010). As a result, it ranks second in terms of usefulness to the digital forensics investigation. A significant variety of computer crimes presents a wide array of data sources that can be used during the process of investigation. The types of these sources as well as their usefulness vary depending on the nature of a crime. Still, it is possible to classify them in terms of their value for each specific case, which was demonstrated in the research. However, it should be noted that in most cases, the usefulness of the described data sources depends on the skills and equipment possessed by the investigation team. Moreover, in some cases, for example, the insider file deletion, the preventive measures taken by the attackers can render any of the available data sources useless. As a result, it is clear that the process of digital forensics investigation must be improved on a regular basis to follow the pace of development of the contemporary information technologies.

The ouster of Vikram Pandit, and what that means for big banks Research Paper
The ouster of Vikram Pandit, and what that means for big banks - Research Paper Example This paper will address Panditââ¬â¢s ouster, and describe how this major event in Citigroup will influence the future operations of Citibank, as well as other banks in the same industry. Mr. Pandit took over as the bankââ¬â¢s CEO in 2007 when the bank was in a financial turmoil, but slightly recovered the profitability of the bank in 2010. Under Panditââ¬â¢s management, much of Citiââ¬â¢s resources were devoted for future profitability. Expanding market to the developing countries was a prospective Pandit held (David, Suzanne, and Dan 1-2). The reasons offered for Panditââ¬â¢s ouster emanate from struggles to recover from past financial crises at the bank. Mr. Pandit was forced to resign after the board of Directors at Citi bank felt that he managed the bank poorly. The board also claimed lack of appropriate communication from the CEO on vital business matters. During the tenure of Pandit, the shares of Citigroup fell by 89%, which resulted in a revolt by shareholders over his executive pay. The Federal Reserve also rejected Citigroupââ¬â¢s plan to purchase back stock. In addition, there was a $2.9 million write-down by Morgan Stanley, of a brokerage joint venture. All these unfortunate happenings can be numerically represented, but most probably point to poor judgment, rather than day-to-day oversight of specific business units (David 2). Michael Corbat, Panditââ¬â¢s replacement, may not perform as Pandit, who was credited a well performer, who knew the positions of the bank inside out. Corbatââ¬â¢s strategic directions for future of the company are also still uncertain. Many challenges Corbat, as he will feel the pressure of impressing quickly, since the bankââ¬â¢s shareholders are now frustrated about the bankââ¬â¢s uncertainty. Citigroup investment bank is a potential victim of shrinkage. It is enormous, but with uneven revenue since the times of the financial crisis. This continued decline has to be addressed in order to gain stability again. Mr. Corbat will also have to deal with the ââ¬Å"black boxâ⬠reputation of the bank. Observations show that the bankââ¬â¢s disclosures are not as comprehensive as those of other banks are. In order to regain the confidence of investors, Corbat has to tackle this issue also. Consumers should expect to feel the difference between Citi managed by Pandit, and Citi managed by Michael Corbat, Panditââ¬â¢s successor. This kind of transition at Citi may not positively influence on the financial health of the US banking industry, and the general US economy. This is because Citi is a bank that has been considered ââ¬Ëimportantââ¬â¢ by the regulators, amid financial crisis. It is a troubled bank, and still struggles to gain stability. Pandit was a CEO that had set out to turn around the case of Citi bank, and ensure its total economic recovery. However, by firing such a dedicated CEO, Citi bank risks continued vulnerability to financial crises. The shareholde rs of Citi bank continue to be adversely affected by the bankââ¬â¢s prolonged stagnation in financial instability. However, more parties will feel the pinch of this as it will affect the whole banking industry as well as the national economy. Citi is in the process of repairing its balance sheet, it is then expected that it will cut down on customer lending, in a bid to save more. Its customers will not access

The mechanical testing of a silk fibrion (SF) scaffold seeded with Essay
The mechanical testing of a silk fibrion (SF) scaffold seeded with MSCs in Colon Engineering - Essay Example TEC was spawned by the rats 100% with no regard to source of tissue, the initial occurrence of adult cells of engineered intestine or an engineered tissue. Architecture of TEC is same as acetyl cholinesterase, inherent actin staining on muscularis propria staining for actin identified in deoxynucleotidyl transferase-mediated deoxyuridine triphosphate-digoxigenin nick end labeling assay similar to native colon, lamina propria of a linear distribution, ganglion cells, S100-positive cells, and a terminal (Fonkalsrud 1999). By the use of cavity information specified in function of vitro dependable with advanced colonocytes, and an optimistic response of short circuit current to theophylline demonstrating integral transfer of ion. TEM exhibited regular architecture of micro part (Dayton 2000). Architecture of colon was retained in anastomosis with uncultured uptake of fluid visualization. The rats survived embedding and 100% of all them spawned TEC. Almost 60,000 OU was obtained from every pup colon of rat. This is an adjustable quantity as the surface area of tissue in every case may differ. For the reason that adult colons were very large, every rat colon of adult rat gave a result of a specimen of 800,000 (Meagher, 1998). These were inclusive of the ones spawning subordinate TEC and the ones embedded with adult tissue TEC. The TEC average size was 4cm by 5cm by 4 cm. There was absolutely no measure of TEC going below 3cm by 3cm by 2 cm, and the prevalent one was 6cm by 8cm by 7.5 cm. This is shown below TEC was paramount visible as a minor cyst with a lumen that was mucus-filled lumen the second week onwards (Shepherd 1990). Prior to that, there was no visible lumen recognized. Sequential growth took place the weeks after the second week. 9. Grikscheit TC, Ochoa ER, Ramsanahie A, et al 2001. Tissue engineered colon, characterization and comparison to native colon.
