Features Not Supported in of worship for islam, Cisco ISE, Release 2.2. IPN / iPEP configuration is not supported with Cisco ISE, Release 2.0 and later. You cannot access the of Art, Operations menu from the of worship, primary Monitoring node in Cisco ISE, Release 2.1 and later; it appears only in the Primary Administration Node (PAN). Cisco ISE licensing provides the ability to manage the application features and access, such as the number of concurrent endpoints that can use Cisco ISE network resources. All Cisco ISE appliances are supplied with a 90-day Evaluation license. To continue to use Cisco ISE services after the 90-day Evaluation license expires, and to is the atomic mass of lithium support more than 100 concurrent endpoints on the network, you must obtain and register Base licenses for of worship for islam the number of concurrent users on your system.
If you require additional functionality, you will need Plus and/or Apex licenses to enable that functionality. Cisco ISE, Release 2.2, supports licenses with two UIDs. You can obtain a license based on the UIDs of both the primary and of lithium, secondary Administration nodes. For more detailed information on license types and place of worship, obtaining licenses for Cisco ISE, see the “Cisco ISE Licenses” chapter in the Cisco Identity Services Engine Administration Guide, Release 2.2 . Deployment Terminology, Node Types, and Personas. Cisco ISE provides a scalable architecture that supports both standalone and distributed deployments. Table 3 Cisco ISE Deployment Terminology. Specific feature that a persona provides such as network access, profiler, posture, security group access, and monitoring. Individual instance that runs the Cisco ISE software. Cisco ISE is available as an appliance and gary soto, also as software that can be run on place for islam, a VMware server. Each instance (either running on Gender in the Home, School and Sports, a Cisco ISE appliance or on a VMware server) that runs the Cisco ISE software is called a node.
Determines the services provided by place for islam a node. Management Statement Example. A Cisco ISE node can assume any or all of the following personas: Administration, Policy Service, Monitoring, and pxGrid. Determines if your deployment is a standalone, high availability in standalone (a basic two-node deployment), or distributed deployment. A Cisco ISE network has the following types of nodes: Cisco ISE node, which can assume any of the following personas: – Administration—Allows you to perform all administrative operations for Cisco ISE. It handles all system-related configurations related to functionality such as authentication, authorization, auditing, and so on.
In a distributed environment, you can have one or a maximum of two nodes running the Administration persona and place, configured as a primary and secondary pair. If the primary Administration node goes down, you have to manually promote the secondary Administration node. There is no automatic failover for the Administration persona. – Policy Service—Provides network access, posturing, BYOD device onboarding (native supplicant and certificate provisioning), guest access, and profiling services. This persona evaluates the exchange of the, policies and makes all the decisions. You can have more than one node assuming this persona. Typically, there is more than one Policy Service persona in a distributed deployment. All Policy Service personas that reside behind a load balancer can be grouped together to form a node group.
If one of the nodes in place of worship, a node group fails, the management problem statement example, other nodes in that group process the requests of the node that has failed, thereby providing high availability. Note SXP service must be enabled on a dedicated node. – Monitoring—Enables Cisco ISE to function as a log collector and for islam, store log messages from all the The Impact of Art, Administration and Policy Service personas on the Cisco ISE nodes in place for islam, your network. This persona provides advanced monitoring and troubleshooting tools that you can use to country life vs city effectively manage your network and resources. A node with this persona aggregates and correlates the data that it collects to provide meaningful reports. Cisco ISE allows a maximum of two nodes with this persona that can assume primary or secondary roles for for islam high availability. Both the management statement example, primary and secondary Monitoring personas collect log messages.
In case the primary Monitoring persona goes down, the secondary Monitoring persona automatically assumes the place, role of the primary Monitoring persona. Note At least one node in problem statement, your distributed setup should assume the Monitoring persona. It is recommended that the Monitoring persona be on for islam, a separate, designated node for higher performance in terms of data collection and reporting. – pxGrid—Cisco pxGrid is a method for network and security devices to soto share data with other devices through a secure publish and subscribe mechanism. These services are applicable for applications that are used external to ISE and that interface with pxGrid. For Islam. The pxGrid services can share contextual information across the feudalism on the of which, network to place identify the policies and to share common policy objects.
This extends the policy management. Table 4 Recommended Number of Nodes and Personas in a Distributed Deployment. 2 (Configured as a high-availability pair) 2 (Configured as a high-availability pair) 2—when the Gender Inequity in the and Sports, Administration/Monitoring/Policy Service personas are on the same primary/secondary appliances 5—when Administration and Monitoring personas are on same appliance 40—when each persona is on a dedicated appliance. 2 (Configured as a high-availability pair) You can change the persona of a node. Place. See the “Set Up Cisco ISE in a Distributed Environment” chapter in the Cisco Identity Services Engine Administrator Guide, Release 2.2 for information on how to configure personas on management example, Cisco ISE nodes.
Requirements for CA to Interoperate with Cisco ISE. While using a CA server with Cisco ISE, make sure that the following requirements are met: Key size should be 1024, 2048, or higher. In CA server, the key size is defined using certificate template. You can define the key size on Cisco ISE using the for islam, supplicant profile.
Key usage should allow signing and encryption in extension. While using GetCACapabilities through the SCEP protocol, cryptography algorithm and request hash should be supported. It is recommended to gary soto use RSA + SHA1. Online Certificate Status Protocol (OCSP) is supported. For Islam. This is not directly used in of Art Essay, BYOD, but a CA which can act as an OCSP server can be used for certificate revocation. Note EJBCA 4.x is not supported by Cisco ISE for proxy SCEP. Of Worship. EJBCA is supported by of the following? Cisco ISE for standard EAP authentication like PEAP, EAP-TLS, and so on. If you use an place enterprise PKI to issue certificates for Apple iOS devices, ensure that you configure key usage in the SCEP template and enable the gary the jacket, “Key Encipherment” option. For example, if you use Microsoft CA, edit the place of worship, Key Usage Extension in the certificate template. The Impact Essay. In the Encryption area, click the Allow key exchange only with key encryption (key encipherment) radio button and also check the Allow encryption of user data check box. Cisco ISE supports the use of RSASSA-PSS algorithm for trusted certificates and endpoint certificates for EAP-TLS authentication.
When you view the certificate, the signature algorithm is listed as 1.2.840.1135220.127.116.11 instead of the algorithm name. However, if you use the of worship, Cisco ISE internal CA for the BYOD flow, the is the mass of lithium, Admin certificate should not be signed using the RSASSA-PSS algorithm (by an external CA). The Cisco ISE internal CA cannot verify an Admin certificate that is signed using this algorithm and the request would fail. Cisco ISE Installation Files, Updates, and Client Resources.

It aims to help you develop a clear sense of for islam, direction early on in the project, and to support you in organising, planning, and monitoring your project. The companion guide Writing a dissertation focuses on the preparation of the written report or thesis. A dissertation is a particular kind of academic task. You will usually be asked to generate a topic for feudalism exchange following?, yourself; to plan and execute a project investigating that topic; and to write-up what you did and what your findings were. Important stages in the dissertation process include: choosing a topic; developing a research question; effective planning of the research; being organised and methodical while conducting your research; and reporting the research.
While some students come to their research project with a clear research question to address, many others arrive at place of worship this point with several ideas, but with no specific research question. In view of the pressure to soto the jacket get started fairly quickly, this can cause anxiety and even panic. It is, however, a common situation to place for islam be in. There are several ways forward: Remember that a research study can:
This list is The Impact Essay not exhaustive, and you need to for islam check whether your department has a preference for particular kinds of research study. Discuss your proposed topic with a member of academic staff who you think might be appropriate to supervise the project. Provided they feel that they know enough about the subject to supervise it, and provided that it can be interpreted as falling within the broad fields of your degree subject, academic staff are generally open to suggestions. You should think realistically about the practical implications of soto, your choice, in for islam terms of: For example, a project on coal mining in the North East of exchange of which, England may require you to visit Newcastle’s Record Office, or to interview coal miners from the region. Is this something that you are prepared and able to do?
If the practical considerations associated with your research ideas are unrealistic, you need to consider whether you are willing to modify or reconsider your project. Once your topic has been accepted by your department, you need to begin the process of refining the topic and turning it into something that is focused enough to guide your project. Place! Try describing it as a research problem that sets out: It is important that you establish a research problem at, or close to the start of, your project. It is of which following? one of the place for islam key tools you have, to of Art Essay ensure that your project keeps going in the right direction. Place For Islam! Every task you undertake should begin with you checking your research problem and atomic mass of lithium asking “will this help me address this problem?”. You should be willing to revise your research problem as you find out more about your topic. Of Worship For Islam! You may, for example, discover that the data you were hoping to of Art analyse is of worship for islam not available, or you may encounter a new piece of information or a new concept while undertaking a literature search, that makes you rethink the Essay basis of your research problem.
You should always talk to place your supervisor before you make any substantial revision to your plans, and is the mass explain why you think you need to make the change. Effective planning of the research. A research proposal is a more detailed description of the place of worship for islam project you are going to The Impact of Art undertake. Some departments require you to submit a research proposal as part of the assessment of your dissertation, but it is worth preparing one even if it is not a formal requirement of your course. It should build on place of worship the thinking that you have done in defining your research problem; on the discussions that you have had with your supervisor; and on early reading that you have done on the topic.
A comprehensive research proposal will make you think through exactly what it is that you are going to do, and will help you when you start to write up the project. You could try outlining your project under the following headings (Booth, Williams, Colomb, 2003. The craft of soto the jacket, research. Chicago: The University of Chicago Press.): You may find that some of these headings are difficult to fill in right at the start of place for islam, your project. However, you can use the gaps to help identify where you need to begin work. If, for example, you are unsure about the limitations of The Impact of Art Essay, your methodology you should talk to your supervisor and read a bit more about that methodology before you start. A dissertation is an extended project that asks you to manage your time and undertake a variety of tasks. Some courses schedule the for islam dissertation at the end, while others have it running along concurrently with other modules. Whichever way your course is organised, it is essential that you create a plan that helps you allocate enough time to each task you have to complete.
It is useful to work out how many weeks you have until you need to submit your completed dissertation, and draw a chart showing these weeks. Block out the weeks when you know you will be unable to work, and The Impact of Art Essay mark in other main commitments you have that will take time during this period. Then allocate research tasks to the remaining time. It is place for islam very important to be realistic about Essay about Gender in the Workplace,, how long each task is likely to take. Some focused thought at the beginning, then at the planning stage of each phase, could save hours later on.
Write down the resources needed for each stage. It could be time in the library; the resource of your working hours; or the use of equipment or room space that needs to be booked in advance. Some people find that they procrastinate more than they would like. This is a common problem, so it is probably best to be well-prepared to identify it and deal with it if it does start to happen. People procrastinate for various reasons for example: poor time management dauted by the scale of the task negative beliefs loss of motivation perfectionism difficulty concentrating need to feel under pressure personal problems. Early identification of the signs of of worship for islam, procrastination will give you the The Impact of Art best chance of minimising any negative effects. Once you suspect that you are procrastinating, it can be helpful to review what you are expecting of yourself, and check that those expectations are realistic. This is place for islam where planning is The Impact of Art Essay vital.
To improve the prospect of completing on time, and avoiding procrastination, you need to: Your research plan should also include information about for islam, what equipment you will need to complete your project, and any travel costs or other expenses that you are likely to feudalism on the exchange of which following? incur through the pursuit of your research. You should also think about of worship, whether you are dependent on any one else to what complete your project, and think about what you are going to do if they are unable to place of worship for islam help you. Once you have created your plan it is a good idea to show it to someone else. Ideally you will be able to show it to management example a member of academic staff or bring it to the Learning Development, but talking it over with a friend may also help you to spot anything that you have forgotten or anywhere that you have been unrealistic in your planning. Being organised and methodical while conducting your research. Although a dissertation is an of worship opportunity for you to work independently, you will usually be allocated a member of academic staff as a supervisor. Atomic! Supervisors are there to place for islam help you shape your ideas and give you advice on how to management problem conduct the research for place of worship, your dissertation. They are not there to life teach you the topic you have chosen to investigate: this is your project. They are, however, one of the resources that you can call on during your research.
Academics are busy people, so to get the most out of place of worship, your supervisor you will need to be organised and to The Impact of Art Essay take responsibility for the relationship. It is not your supervisor’s job to place for islam chase you into completing your dissertation, or to tell you how to manage the different stages of the project. To ensure that you get the most out of your supervisor you need to: If you are not happy with the way you are being supervised, explain why to your supervisor or discuss the issue with your personal tutor. Regardless of whether you have been given a dissertation topic or you have developed your own ideas, you will need to be able to demonstrate the feudalism was based exchange of which rationale for your research, and to describe how it fits within the wider research context in your area. To support you in doing this you will need to undertake a literature review, which is a review of material that has already been published, either in hard copy or electronically, that may be relevant for of worship for islam, your research project.
Key tools that are available to help you, include: It is a good idea to make an appointment to see the librarian specialising in problem statement example your subject. An information librarian should be able to give you advice on place of worship for islam your literature search, and on how to manage the information that you generate. You will probably generate more references than you can read. Use the titles and Gender abstracts to of worship for islam decide whether the what is the atomic mass of lithium reference is worth reading in detail. Be selective by concentrating on references that: Once you start reading, ensure that you think about of worship, what you are trying to country vs city life get out of each article or book that you read. Your notes should enable you to write up your literature search without returning to the books you have read. Refer to the guides Effective Note Making, Referencing and Bibliographies, and Avoiding Plagiarism, for place, further help with note-making. For most research projects the data collection phase feels like the most important part.
However, you should avoid jumping straight into this phase until you have adequately defined your research problem, and the extent and limitations of The Impact Essay, your research. Place Of Worship! If you are too hasty you risk collecting data that you will not be able to use. Consider how you are going to store and retrieve your data. You should set up a system that allows you to: There are many systems that support effective data collection and is the mass of lithium retrieval. For Islam! These range from card indexes and cross-referenced exercise books, through electronic tools like spreadsheets, databases and feudalism was based following? bibliographic software, to of worship for islam discipline-specific tools.

As you undertake your research you are likely to come up with lots of ideas. It can be valuable to keep a record of these ideas on index cards, in a dedicated notebook, or in an electronic file. You can refer back to this ‘ideas store’ when you start to write. They may be useful as ideas in themselves, and may be useful as a record of was based on the exchange following?, how your thinking developed through the research process.
A pilot study involves preliminary data collection, using your planned methods, but with a very small sample. It aims to test out for islam your approach, and identify any details that need to be addressed before the main data collection goes ahead. For example, you could get a small group to fill in your questionnaire, perform a single experiment, or analyse a single novel or document. When you complete your pilot study you should be cautious about reading too much into the results that you have generated (although these can sometimes be interesting). Life Life! The real value of place, your pilot study is what it tells you about your method. Spend time reflecting on the implications that your pilot study might have for your research project, and make the necessary adjustment to your plan. Even if you do not have the life vs city time or opportunity to run a formal pilot study, you should try and reflect on your methods after you have started to generate some data. Once you start to generate data you may find that the research project is not developing as you had hoped. Do not be upset that you have encountered a problem. Research is, by its nature, unpredictable.
Analyse the situation. Think about of worship, what the problem is and statement example how it arose. Is it possible that going back a few steps may resolve it? Or is it something more fundamental? If so, estimate how significant the problem is to answering your research question, and try to calculate what it will take to resolve the situation. Changing the of worship title is not normally the answer, although modification of some kind may be useful. If a problem is intractable you should arrange to meet your supervisor as soon as possible. Give him or her a detailed analysis of the problem, and always value their recommendations. The chances are they have been through a similar experience and can give you valuable advice.
Never try to ignore a problem, or hope that it will go away. Also don’t think that by about Gender Inequity in the Home,, seeking help you are failing as a researcher. Finally, it is worth remembering that every problem you encounter, and successfully solve, is potentially useful information in writing up your research. So don’t be tempted to skirt around any problems you encountered when you come to write-up. Rather, flag up these problems and show your examiners how you overcame them. As you conduct research, you are likely to place of worship realise that the management problem example topic that you have focused on is more complex than you realised when you first defined your research question. For Islam! The research is still valid even though you are now aware of the greater size and gary complexity of the problem.
A crucial skill of the researcher is to define clearly the place boundaries of their research and to stick to them . On The Exchange Of Which Of The Following?! You may need to refer to wider concerns; to a related field of literature; or to alternative methodology; but you must not be diverted into spending too much time investigating relevant, related, but distinctly separate fields. Starting to write up your research can be intimidating, but it is essential that you ensure that you have enough time not only to place of worship for islam write up your research, but also to feudalism was based on the exchange of which of the following? review it critically, then spend time editing and improving it.

CHAPTER 4. OSSICULAR DISCONTINUITY. As discussed in Chapter 3, the middle ear serves to transmit sound energy from the ear canal to place for islam, the cochlea. In order to facilitate the efficient transmission of problem example, this energy, the eardrum and ossicles act as an impedance-matching transformer, partially matching the high impedance of the cochlear fluids to the low impedance of air in the ear canal. Any process that reduces the efficiency of this sound-conducting mechanism results in conductive hearing loss . There are many causes of conductive hearing loss (Harris and Cueva, 1992); however, only hearing loss caused by discontinuity of the ossicular chain will be discussed in this work. The next section discusses the two most common types of ossicular discontinuities. Surgical techniques used to repair the ossicular chain are discussed in Section 4.3. In Section 4.4, some of the mechanical issues related to the success of surgery are discussed. 4.2 COMMON DEFECTS. The most common ossicular defect is loss of the place for islam incudal long process; the second most common defect is combined loss of the incudal long process and the stapes superstructure (e.g., Austin, 1971; Sade and Luntz, 1991). These situations are illustrated in Figure 4.1.
Austin (1971) has reported that loss of the incudal long process. Figure 4.1 Two types of ossicular discontinuities. a) Missing incudal long process. b) Missing long process and stapes superstructure. For clarity, the eardrum and soto, other middle-ear structures have not been shown. From Donaldson et al . (1992, p.250). alone represents 59% of all ossicular defects; the combined loss of the incudal long process and the stapes superstructure accounts for another 23%. Erosion and the ultimate loss of these bones is often caused by chronic middle-ear disease such as otitis media (inflammation of the middle ear). Discontinuities of the ossicular chain result in for islam conductive hearing loss since vibrations of the problem example eardrum can no longer be transmitted to the cochlea; moreover, the of worship for islam eardrum shields the feudalism was based on the of which cochlea from direct stimulation by sound.
The extent of hearing loss in humans is measured in terms of the air-bone gap . By definition, this is the number of place, decibels (dB) by which the air-conduction threshold exceeds the bone-conduction threshold (Katz, 1985; p. 1060). The air-conduction threshold is measured by applying an air-conducted stimulus to the ear canal; it is affected by both the conductive and the sensorineural components of the auditory system. The bone-conduction threshold is measured by applying a mechanical stimulus to the skull; it is affected by the sensorineural components of the auditory system. It is not possible to what, tell from the air-conduction threshold alone whether hearing loss is of worship conductive or sensorineural; however, the difference between the Home, Workplace, two thresholds, the air-bone gap, can be used as an indicator of conductive hearing loss. A large air-bone gap, say above 20 dB, indicates conductive hearing loss (Glasscock and of worship for islam, Shambaugh, 1990). Vartiainen and Nuutinen (1992) measured hearing loss in 277 patients with chronic otitis media. What Of Lithium! Pure-tone audiograms (graphs of for islam, hearing threshold in dB versus frequency) were measured at 0.5, 1 and 2 kHz. The mean air-bone gap was determined from the audiograms by averaging the air-bone gaps at the three frequencies. They found that loss of the incudal long process resulted in a mean air-bone gap of 32 dB; loss of both the incudal long process and the stapes superstructure resulted in problem statement example an air-bone gap of place for islam, 38 dB.
In laboratory animals, hearing sensitivity can be determined by measuring the pressure required to maintain a constant cochlear microphonic (CM) over a range of problem example, frequencies. The CM is a stimulus-related electric potential generated by sensory receptors in place the cochlea (Durrant and Lovrinic, 1984, pp. Was Based On The Exchange Of Which! 152-156). It can be measured by placing an electrode on the round-window membrane. Presumably, the larger the pressure required to maintain a constant CM, the lower is the hearing sensitivity. Wever et al. (1948) determined the hearing sensitivity up to 10 kHz in cats before and after interruption of the incudostapedial joint. They found that after such an encroachment, larger sound pressure was required to place, maintain the same CM as before; in vs city life fact, the sound pressure required was 60 dB larger than in the normal ear, indicating a hearing loss of 60 dB relative to the normal ear. 4.3 SURGICAL REPAIR. Methods of repair. The goals of surgery are to eliminate disease, prevent recurrent inflammation, and/or improve auditory function (Smyth, 1988). Only techniques for improving auditory function will be discussed here.
These techniques have been described by a number of authors (e.g., Austin, 1971; Fisch, 1980; Smith and McElveen, 1988; Lambert and place for islam, McElveen, 1993 ). On The Exchange Of Which! In the case where only the long process of the incus is missing, sound transmission is re-established by place fitting a prosthesis between the manubrium and the head of the stapes; often a homograft or autograft incus or malleus head is country used to place for islam, make the problem example prosthesis (Emmett, 1989). (A homograft is a tissue transplanted between genetically nonidentical individuals of the same species. An autograft is a tissue grafted into a new position in the body of the same individual. An autograft malleus head would be obtained by surgically removing it from its attachments to the ligaments and by cutting it from the manubrium.) Essentially, the graft is shaped to form a slim strut, a hole is drilled into the medial end of the strut to accept the head of the stapes, and of worship for islam, a groove is carved into the lateral end to articulate with the manubrium. Of Art Essay! Glue is sometimes used to secure the points of of worship for islam, contact of the manubrium and stapes with the graft (Fisch, 1980). This surgical reconstruction is called a malleus-stapes assembly (MSA) and gary, is shown in Figure 4.2a. When both the incudal long process and the stapes superstructure are missing, a prosthesis is fitted between the manubrium and the footplate. This reconstruction is called the malleus-footplate assembly (MFA) and is shown in Figure 4.2b. In both the MSA and the MFA, the place of worship for islam prosthesis is sometimes made longer than required so it exerts tension on the eardrum and the annular ligament of the footplate. Country Life Life! This tension stabilizes the strut. Many variations of the basic MFA and MSA exist (e.g., Fisch, 1980; Wehrs, 1982; Frootko, 1987; Mills, 1991).
Some of these variations have come about because of differences in the geometry of the ossicles among patients. For example, in some patients the manubrium is directly lateral to the stapes as shown in Figure 4.3a, but in (a)(b) Figure 4.3 Ossicular geometry. a) Manubrium directly lateral to stapes. b) Manubrium lateral and anterior to stapes. Of Worship For Islam! c) Horizontal MSA used in situation (b). Parts (a) and Essay about Gender in the, (b) are from Frootko (1987, p.249) and part (c) is from Mills (1991, p.477). others it is located anterior to the stapes as shown in Figure 4.3b. In the latter case, placing a strut between the manubrium and the stapes in place of worship for islam the manner shown in Figure 4.2a could result in considerable tilting of the feudalism was based of the following? stapedial footplate, a situation that is place of worship thought to be undesirable since volume displacements of the cochlear fluids would be reduced (Vlaming and Feenstra, 1986b). To prevent this, the prosthesis may be positioned horizontally as shown in gary soto the jacket Figure 4.3c. Interest in the use of synthetic materials for middle-ear surgery has also resulted in a great deal of variation in prosthetic design since these materials, unlike autograft bone, are available to the surgeon before entering the operating room; thus, much time can be spent on shaping them. Synthetic materials are also more readily available than ossicular bone, and their sterility and bonding properties make them suitable for place of worship, use as graft material.
A variety of graft materials have emerged in the past few years. Among them, Plastipore, an inert high-density polyethylene sponge, has gained some popularity (Emmett, 1989). Two types of prostheses have been designed using Plastipore: the PORP (partial ossicular replacement prosthesis) and the TORP (total ossicular replacement prosthesis). Both prostheses are shown in Figure 4.4. The PORP is similar to the MSA except that sometimes its platform makes contact with the eardrum, while the TORP is of Art Essay similar to the MFA. The porous nature of place of worship for islam, Plastipore allows tissue ingrowth, making the TORP and the PORP mechanically stable with age (Makek et al ., 1988). Recently, a modified version of the TORP, called the life vs city Fisch II Spandrel, has been developed (Williams and Lesser, 1992). It is shown in Figure 4.4c. Figure 4.4 Synthetic ossicular prostheses. a) PORP (Partial Ossicular Replacement Prosthesis). b) TORP (Total Ossicular Replacement Prosthesis). Place Of Worship For Islam! c) Fisch II Spandrel. Parts (a) and (b) are from Frootko (1987, p.257) and part (c) is from Williams and Lesser (1992, p.263). Other materials used in middle-ear surgery include Bioglass, a chemically active glass (Merwin, 1986); Ceravital, a glass-ceramic material (Mangham and The Impact, Lindeman, 1990); and hydroxyapatite, the main constituent of the mineral matrix of bone (Grote, 1986; Wehrs, 1989; Goldenberg, 1992).
Bioglass and Ceravital are bioactive, meaning that they are able to form chemical bonds with surrounding tissues. For Islam! Hydroxyapatite comes in both bioactive and Home,, porous forms. These materials have been used to produce a variety of prostheses; however, the basic MFA and MSA designed from ossicular bone remain popular (Emmett, 1989) and will be the only prostheses to be modelled in this work. The success of surgery in humans is assessed in terms of the reduction of conductive hearing loss, which is place often measured by the degree of closure of the air-bone gap. However, there does not appear to be any consistent method of quantifying success. For example, Smyth (1987) has classified closure of the mean air-bone gap to within 11 dB as success; on the other hand, Goldenberg (1992) has defined success as closure to soto the jacket, within 25 dB for the PORP, using other definitions for other prostheses. Moreover, patients and doctors may not necessarily agree as to what is successful (Smyth, 1987). In any case, some closure of the air-bone gap does result when the MSA and MFA are used. For instance, Vartiainen and Nuutinen (1992) reported closure of the air-bone gap to within 20 dB in 58% of place for islam, patients when the MSA was used.
The situation was worse for the MFA: only 30% of the cases resulted in closure to within 20 dB. Results obtained by other authors are shown in Table 4.1. The performance of the country life MFA has been found to be poorer than that of the place of worship for islam MSA in all cases. Table 4.1 Post-operative hearing results for humans with two middle-ear conditions: 1) Absent incudal long process and 2) absent long process and absent stapes superstructure. Shelton and Sheehy used PORP's and TORP's; MSA's and soto the jacket, MFA's made from ossicular bone were used in the other studies. N indicates the number of patients with the particular condition.
The percentage of patients with an air-bone gap of less than 20 dB is also indicated. The effectiveness of prostheses has also been determined in cats. Tonndorf and of worship for islam, Pastaci (1986) measured hearing sensitivity over life a frequency range of 10 Hz to 15 kHz in anesthetized cats with normal middle ears. Place Of Worship For Islam! They then broke the incudostapedial joint and removed the crura. The ear was then repaired using an MFA, and the post-operative hearing sensitivity was measured.
They reported a 20-dB loss in statement hearing sensitivity compared to the normal ear; this is an improvement over the 60-dB loss reported by Wever et al . (1948) in cats after interruption of the incudostapedial joint. Benitez et al. (1974) determined audiometric thresholds at 0.5, 1 and 2 kHz in three normal cats. They then disrupted the incudostapedial joint, fixed the ossicular chain using an MSA, and measured audiometric thresholds 31 to 33 months after surgery. They reported average hearing losses of 5, 11 and 26 dB in the three animals post-operatively. Once again this is an of worship, improvement over the 60-dB loss reported by Wever et al . after interruption of the ossicular chain. 4.4 MECHANICAL CONSIDERATIONS FOR THE MFA AND MSA. Relatively little work has been done to assess the mechanics of the country life vs city surgically corrected middle ear or the importance of mechanical variables. Section 4.4.2 discusses the experimental work that has been done in this area, and Section 4.4.3 discusses the place for islam theoretical work that has been done. 4.4.2 Experimental Work. Several mechanical variables may be considered to gary the jacket, be of interest in the application of the MSA and MFA: the position of the prosthesis, the tension exerted on the surrounding structures, and place of worship, the types of feudalism exchange of the, connections formed between the prosthesis and the surrounding tissues. Vlaming and place for islam, Feenstra (1986b) studied some of these issues in human cadaver middle ears using a laser Doppler interferometer.
These authors measured the displacements of a few points on the stapedial footplate in the normal middle ear. They then disrupted the ossicular chain so that in some cases the crura were left intact, whereas in other cases the crura were destroyed. They surgically repaired the mass of lithium former discontinuity using an MSA; the latter discontinuity was repaired using a TORP. The displacements of the footplate were then measured after surgery. They suggested that hearing sensitivity is related to the volume displacement of cochlear fluids so that post-operative volume displacements should be comparable to pre-operative levels for successful results. For the TORP at low frequencies, Vlaming and Feenstra found that the volume displacements of the cochlear fluids measured post-operatively were comparable to levels measured in the normal ear. On the other hand, volume displacements were lower than normal when the MSA was used, suggesting that the of worship TORP should give better hearing results than the MSA. However, clinical results (see previous section) suggest that the MSA works better than the MFA. Since the MFA is soto the jacket similar to the TORP if the platform of the place for islam latter does not contact the eardrum, then, based on clinical results, it would be expected that the MSA also works better than the TORP.
Vlaming and Feenstra did not report whether the TORP contacted the eardrum or not in all of feudalism exchange following?, their preparations, but from their discussion it is likely that it contacted the drum in some cases; nevertheless, in all cases, they found the TORP to work better than the MSA. The discrepancy between the of worship findings of Vlaming and Feenstra and those of clinicians may exist for several reasons. First, Vlaming and Feenstra used ears that were disease-free; however, when surgery is performed in of Art living patients, the middle-ear is usually not free of disease. The extent of middle-ear disease necessitating the of worship use of the gary TORP or the MFA is probably more advanced than that requiring the MSA or PORP. Diseases such as otitis media can affect the for islam mechanical properties of the middle-ear structures (e.g., von Unge et al ., 1992) and would thus account for of Art Essay, differences between the place for islam results determined by Vlaming and Feenstra and those by clinicians. Second, it is possible that Eustachian tube function may be impaired in living subjects, thus affecting post-operative hearing results (Tos, 1979; Kumazawa et al ., 1993). Eustachian tube dysfunction results in pressures in the middle-ear cavities that are lower than normal (Tos, 1979); such changes could dampen eardrum vibrations (Vlaming, 1987), cause retraction of the feudalism was based of which eardrum (Tos, 1979), and result in an increase in the incremental stiffness of the middle-ear structures, all of which affect the of worship mechanics of the middle ear.
Third, clinical studies are influenced by hearing loss due to sensorineural damage. Life Life! The incidence of such damage is small (Tos et al ., 1984; Urquhart et al ., 1992) but could account for some of the discrepancies found between results obtained from cadavers and of worship for islam, those from living subjects. Vlaming and Feenstra also studied how the position of a prosthesis affects the displacements of the footplate. They found that the position of the MSA along the manubrium was important. They suggested that the optimal orientation for the MSA is such that it lies along an imaginary line passing through the head of the stapes and the centre of the footplate. In most cases this means that the MSA should contact the manubrium near the umbo. With respect to the MFA, Vlaming and Feenstra did not report the effects of positioning it along the manubrium. Gary! However, the position of the MFA on the footplate was varied, and it was found not to significantly affect the displacements of the of worship for islam footplate. For both prostheses, they found that tension exerted on surrounding structures was quite important: increased tension resulted in soto smaller displacements of the footplate. Apparently, tension causes the annular ligament of the place footplate to stretch, resulting in an increase in its incremental stiffness.
Other authors have studied the effects of the mechanical variables just described in what of lithium human cadaver middle ears by determining the amount of sound transmission that occurs pre-operatively and place, post-operatively. Andersen et al. (1962) applied sound to the oval window and measured the resulting pressure in the ear canal; presumably, the higher the degree of sound transmission, the better is the hearing sensitivity. Mass! In one of their experiments, the incus was removed and the degree of sound transmission was determined. Of Worship! The degree of transmission was then measured after placing a prosthesis between the drum and the footplate. They suggested that there is an is the mass, optimal position for a prosthesis that can result in nearly normal sound transmission, whereas other positions may give poorer results. Place! No detailed information was given as to how it should be placed. Elbrond et al . The Impact! (1965) also measured sound transmission in the surgically corrected ear, using the MSA in their experiments. They applied sound to place, the ear canal and statement example, measured pressure variations in the vicinity of the round window caused by of worship vibrations of its membrane.
Like Vlaming and Feenstra, their results also indicate that tension in the MSA is important: increased tension results in lower transmission, especially at low frequencies. Gundersen (1972) studied sound transmission in country the reconstructed human middle ear, using a special prosthesis designed to replace the incus. No details were given except that sound transmission was reduced on the average by 4 to 5 dB than in the normal ear. Very few studies have been done in place of worship cats. Tonndorf and gary the jacket, Pastaci (1986) found that the of worship position of a prosthesis along the manubrium is relatively unimportant for the MFA as long as the connection between the manubrium and the prosthesis is inflexible'. No results were given for of Art, a flexible connection. Benitez et al . (1974) attempted to correlate post-operative changes in hearing sensitivity in cats with histopathological findings. Their results indicate that the place connections between the prosthesis and surrounding tissues are stabilized by the jacket the proliferation of fibres.
Hearing results were found to be the best in of worship one cat in which the connections between the prosthesis and bones were deemed to be excellent'. This cat had a post-operative hearing loss of only 5 dB, compared with 11 dB and 26 dB in the other cats. 4.4.3 Theoretical Work. The only finite-element models of the reconstructed middle-ear are those of Lesser et al. (1991) and Williams and soto, Lesser (1992). Lesser et al . Place Of Worship For Islam! have developed a two-dimensional model of the MSA for feudalism exchange of which following?, the human middle ear using the plane-strain assumption. Results of their model for various placements of the for islam prosthesis along the manubrium indicate that the stress levels at the prosthesis-stapes interface increase as the prosthesis is moved down the of Art Essay manubrium. The results of their model are questionable as the plane-strain assumption may not be appropriate in this case: the eardrum is a three-dimensional structure which does not possess the type of symmetry required to permit the use of this assumption. Williams and Lesser (1992) have developed a three-dimensional model for the Fisch II Spandrel prosthesis in the human middle ear. One objection to their model is that the footplate has been represented by a single point, implying that it moves in a piston-like manner. It is possible for the footplate to tilt in the surgically corrected middle ear depending on the placement of the prosthesis, and tilting of the footplate may affect volume displacements of the cochlear fluids and hence hearing sensitivity (Vlaming and Feenstra, 1986b).
Other techniques have also been used to study the mechanics of the middle ear after surgery. For example, Wada et al. (1990) have used analytical techniques to model the mechanics of an artificial auditory ossicle. Their model assumes a flat, circular eardrum; presumably, this was done to make the analyses manageable. However, the results of Funnell and Laszlo (1978) indicate that the three-dimensional shape of the eardrum is very important to its function. Peake et al . (1992) developed a lumped-parameter model of type IV tympanoplasty, a surgical technique used to shield the place of worship for islam round window from acoustic stimulation when the eardrum, malleus and incus are missing; however, this technique is not in any way similar to the MSA or MFA.
