How Do Ferrite Cells Work To Make A Magnetic Generator?
Views:4 Author:Site Editor Publish Time: 2020-09-15 Origin:Site
A ferrite core is a piece of metal used in a magnetic generator. The core consists of a ferrous alloy, which contains iron, magnesium, or zinc. Ferrite cores can be classified into two broad categories: open air-type and closed air-type.
Ferrite cores have high tensile strength and are very durable. They can withstand a lot of impact and wear and tear. Ferrites can be formed from a number of different metals. Ferrites are usually used as the core component in magnetic generators to provide a magnetic field.
Ferrite cores are often referred to as closed air ferrites or manganese zinc ferrite. Closed air ferrites are very strong and are more dense than open air-type ferrite. Ferrites are formed when iron is magnetized and the electrons in the iron atoms gain an extra electron. Once the electrons gain an extra electron, a ferrite is formed. Ferrites are known to be one of the strongest metals known. These properties make ferrite a perfect core material for a magnetic generator. However, because of its strength and durability, ferrite is rarely used as a main component.
Open air-type ferrite consists of manganese zinc which is usually the first material used to form a ferrite core. This material has a number of chemical properties that make it ideal for forming a ferrite core. Because manganese is such an effective magnetic conductor, it makes it an ideal component for a magnetic generator. One disadvantage of manganese is that it is a poor conductor of electricity.
A magnet motor that uses ferrite for its core is also known as a wind turbine. In these types of devices, magnets attached to the motor spin when the rotor spins. A wind turbine may also use the power of the magnets to create a magnetic field that would then create a magnetic force to push a turbine through the air.
Due to its tremendous properties, it is no surprise that ferrite is a key ingredient in many core materials. The ability of manganese to be a magnetic conductor and the other elements it contains make it an ideal ferrite for making a magnet motor. The fact that these motors can be used for various purposes makes it a versatile material.
Other materials that may be incorporated into a magnet motor include peroxide, ferroalloys, and magnetite. These materials are also used to manufacture a magnetic generator but have different strengths and properties. Because a magnetic generator is so efficient at producing a magnetic field, these materials are also used to increase the strength and durability of the generator's core. A strong core is essential to the life of a magnetic generator. The core is where most of the magnetic energy is converted into electric power.
The use of a ferrite core material is important when creating a magnetic generator. The strength and durability of a magnetic generator greatly affect the overall performance and efficiency of the machine. If the generator has a low-quality or poorly-made core, it could potentially not produce enough power to run the machine. It could also result in an expensive repair.

Earthbank utilizes exclusively fish waste and wood waste in our operation. The fish waste consists of mainly farmed salmon offal (some wild) from processing plants and farm mortalities from net pens mainly on the West Coast of Vancouver Island. Earthbank also provides the transportation service to haul the waste to our composting site. The wood waste consists of sawmill waste (mainly fir and hemlock bark), ground up land clearing debris and a small amount of sawdust. All materials from the mills are clean and uncontaminated. Only uncontaminated land clearing debris is accepted at our composting site. All land clearing debris is processed (i.e. ground up) before being incorporated for composting.
The fish waste and wood waste are then blended together in a preset formula that can vary depending on the specific wood waste and other factors. The mixed material is then formed into a 'block' that
is capped with a mixed blend of wood waste and partially cured compost to provide a biofilter for odour control of what we refer to as a 'primary block'. As fish waste is brought onto our site, this process is repeated and added to the pre-existing block until it reaches a pre-determined size and/or period of time. Then a new primary block is started.
The primary block is then allowed to sit untouched for a minimum multi-month period depending on the time of year. Primary blocks are not handled at all from April to October. This is essential in order to minimize off-site odour especially during warm weather. The secondary blocks once turned out of 'primary blocks' are turned several times over the next 12 months. This activity can be highly variable, as to timing and frequency depending on time of year and weather conditions. For example, turning is kept to minimum during warm weather, or not done at all. If weather permits, turning of secondary blocks is more frequent in the early spring, or late fall.
The secondary blocks are then turned out into 'tertiary' windrows after approximately 1.5 years of primary and secondary block composting. These windrows can be turned frequently if necessary, as off site odour during this stage of composting is not a concern. The total number of turns can vary, however, there are a minimum of 15 turns before the material is screened for use. Temperatures above 55 degrees Celsius are routinely recorded in fish compost for long periods of time due to the active and high-energy nature of fish compost.
The "overs" from the screening of the finished compost are then recycled back into the active composting process through a variety of processes and functions that Earthbank utilizes to obtain 100 % recycling of all materials brought on site.

If you're considering a holiday in Majorca, it's worth checking the average temperatures for the time of year you are planning to visit.
The climate and temperatures can vary in different areas, depending on how close to the coast, and to the Serra Tramuntera mountain range.
Generally, inland areas reach slightly higher temperatures than in coastal areas, and hotter temperatures are found in the north east of the island as there are less sea breezes affecting that area.
Average Temperatures in Majorca, by month
Although the island enjoys a warm, Mediterranean climate, it can become chilly in winter months, and there are some months when there is a higher chance of rain.

This application note describes the benefits of using the new CellKey™ Small Sample 96W microplate for investigating endogenous receptor function in non-adherent cell lines and primary cells. The Small Sample microplate was designed to use significantly fewer cells per well while maintaining the same reliability and robustness as the CellKey™ Standard 96W microplate.
Analyzing endogenous receptors in non-adherent cell lines and primary cells with the CellKey™ Small Sample 96W Microplate
Primary cells provide the most biologically, and disease relevant context to study endogenous receptor function making them an attractive in vitro model system for drug discovery. However, primary cells can be prohibitively expensive for use in early stages of drug discovery. The CellKey™ Small Sample 96W microplate has a well-bottom area 1/20 the area of the CellKey™ Standard 96W microplate and uses a reduced assay volume. This enables pharmacological analysis of endogenous receptors in the context of primary cells at a significantly reduced cell number per well. In the following case study, data obtained using the Small Sample microplate was directly compared to data generated using the Standard microplate. The results demonstrate that the Small Sample microplate is ideal for cell-based secondary screening assays utilizing primary cells.

Trauma Outcome Prediction in the Era of Big Data: From Data Collection to Analytics
Physiological data of unprecedented volume is generated daily in healthcare. The Big Data approach in medical data analysis could assist clinicians in doing fast and accurate diagnosis and planning early therapeutic interventions, hence improving patients' outcomes and reducing healthcare cost. However, it is still challenging to reliably collect a large amount of data from bedside monitors and to discover knowledge from the physiological data.
In the area of trauma patient care, early recognition and mitigation of secondary injury and hemorrhage could prevent death caused by massive bleeding or improve patients' life quality after treatment. We describe methods that are used in a level I regional trauma center for massive physiological data collection and analysis. An almost 100% collection rate of continuous, automated, high-fidelity data provides the basis for clinical data mining. Within the machine learning framework, we introduce feature design, feature selection, model performance evaluation, and computing issues, which are critical components in large-scale medical data analysis. Validated knowledge from massive data can be used by clinicians in a simple way for decision making or prioritizing care in the busy hospital environment.

What Is Intel Delayed Launcher and Should I Disable It?
Boot time is a common complaint among PC users. Or, to be more specific, how slow it is. You've probably faced it too – you boot your PC, and it takes forever to get all the programs and apps in order. Now, the obvious solution is for you to disable some of these startup apps. One of those happens to be the Intel Delayed Launcher. If you would like to learn more about what it is or if you should disable it, and if so, how to do it, then you came to the right place.
So, What Exactly Is Intel Delayed Launcher
Before we get to the Intel Delayed Launcher, we need to mention what it's a part of. Namely, there's the so-called Rapid Storage Technology, which contains Rapid Recovery Technology, where you will find the delay launcher, or "iastoriconlaunch.exe." For the curious among you, "iastoriconlaunch.exe" is a short form of Intel Array Storage Tech Icon Delayed Launch.
So, what does Rapid Storage Technology do? Simple – it promises you faster drive speed, as well as a faster app launcher. The latter is the same with single SATA drivers as well as multiple RAID storage. If you're the user of the second option, the Rapid Storage Tech will improve the safety of data by mirroring it on every drive. That way, you won't lose any data should the drive die on you.
How Does It Work
This .exe delays your Windows OS boot-up for a period between 30 and 60 seconds as it uses the local – or run – registry settings to automatically execute a user log-in. It does this before a virus, or any malware, have a chance to get to the system files. That way you can use Intel's Rapid Recovery Tech (also a part of Rapid Storage Tech) to recover the hard drive from its recovery partition. Of course, if the OEM has managed to establish one, and if the said partition is maintained with RAID 1 type of mirroring. The partition should also be invisible to the user.
After this little delay, the number one process to launch happens to be "IAStorIcon.exe." It will make the Rapid Storage Tech icon appear, but what it's really there for is delaying the OS. You can, of course, disable this particular Windows service using msconfig, however, be prepared for no delay in recovery.
To put it in simple terms, this little program is a system recovery measure. You are able to enter your OS before a single system file susceptible to virus or malware intrusion. It is effectively there if a virus that's loading during the booting enters your system.
However, what it gives you in protection, it takes away in boot time. If you never use it, you're essentially wasting a good minute of your life per booting sequence. Though fear not if you're running a smaller server or a tiny, multi-drive data storage.
So yeah, whether or not you should disable it might be a difficult decision to make. The best way to put it is this: is your computer protected from viruses? Disable it. Is it prone to infections? Keep it on and power through the boot time.
Listed below are the different methods for disabling the Intel Delayed Launcher, should you opt for option one.
Method #1: Remove Intel Delayed Launcher From All Startup Programs Using Msconfig (For Windows 7 Users)
Before you start, ask yourself: will I need Rapid Storage Tech at a later date? If the answer is "yes," simply disable it right there at startup. Then re-enable it again at a later date when you need it using this same method.
 1. Press Windows + R. This should get you to the Run window.
 2. To open the system config window, type msconfig and press Enter.RUN - msconfig
 3. Scroll down until you locate Intel Rapid Storage Technology. Click to uncheck it, then follow that with Apply and OK. Keep your primary antivirus software on during this step.
 4. Restart your computer. The booting should be faster after all of this.
Method #2: Remove Intel Delayed Launcher From Startup Programs in Task Manager (For Windows 8 and 10 Users)
If you have any of the two OS's that we mentioned above, method #1 won't work. When you do it, you get to the task manager. Follow these steps to successfully disable Intel Delayed Launcher:
 1. To open your task manager, press Ctrl + Shift + Escape.
 2. You should get a window with an expand option that says More details. Click it.Intel Delayed Launcher
 3. Enter the startup tab.
 4. Scroll down and find "Delayed Launcher." To select it, click it once. You will notice how high its startup impact is. Hence, the startup time will be longer.
 5. In the lower right corner click on Disable.
 6. Restart your computer. It should be booting faster after this method.
But What if I Want to Completely Uninstall the Intel Delayed Launcher?
Good question. If you feel like getting rid of Intel Delayed Launcher indefinitely, or rather the Rapid Storage Technology, the procedure is simple. First, you should change your drive from RST RAID back to SATA, all of this from BIOS. Next, go to "Disk Drivers" and uninstall all of the drivers for RST. You can also do this from your programs and features window.
One final pro tip near the end, though. Intel Delayed Launcher might not be what's causing your boot time to lag. Think it through before you decide to disable it.

Unilateral Transfer
What is a 'Unilateral Transfer'
A unilateral transfer is an economic transactions between residents of two nations over a stipulated period of time, usually a calendar year. Typically, these transactions consist of gift exchanges, pension payments and the like, but they can encompass other goods and services as well.
BREAKING DOWN 'Unilateral Transfer'
Unilateral transfers are included in the current account of a nation's balance of payments. They are distinct from international trade, encompassing such things as humanitarian aid and payments made by immigrants to their former country of residence.

In this research we have studied Tabriz temperature inversion using radio-sound information, during the 2004-2008 periods in daily, monthly and seasonally scales. Produced data associated with temperature inversion daily of the surface (2 meters) to 700 H.Pa. Several different measures are used, including the height of the base and the height of the top of the inversion, the temperature at the base and at the top of the inversion, the temperature difference across the inversion, the depth of the inversion and pressure of base and top temperature inversion layer. After reviewing the information and data at first days with weak, medium, and intense and very intense temperature inversion conditions were specified.
The results indicate that mean annual temperature inversion phenomenon in Tabriz is equal to 191 days, 87% of which is related to the radiation temperature inversion and the remaining 13% is related to the subsidence temperature inversion. In total, 24 days intensity temperature inversion have seen which occurred 17 in winter particularly 12 days during the month of January and 7 days in autumn season. Very intense inversions occasions have mostly occurred during the cold season are radiation temperature inversion. In addition to 70% two stage temperature inversions occurred in winter season particularly in the month of January. Findings of this research have shown that restless to thickness inversion layer, peaked intense temperature inversion when hence difference temperature layer.

Plot a plane striking 072 degrees and dipping 24 degrees southeast.
Note: Always mark an orientation mark on your overlay (north is best) so you can return it to its original orientation. Also, for clarity, the stereonet on this and other pages is shown with circles only at 30 degree intervals. In practice, most stereonets are ruled with light lines at 2-degree intervals and heavy lines at 10-degree intervals.
1. Mark off the strike of the plane on the circumference of the stereonet. It's a good idea to mark both ends of the strike, and also sketch a little strike and dip symbol with the right orientation.
2. Rotate the overlay so that the strike line is north-south. Count in the dip angle along the equator.
3. Trace the appropriate great circle.
4. Return the overlay to its upright position.
It may happen that the great circle you need to plot does not coincide with a plotted great circle. In that case interpolate between the two nearest plotted circles.

The Top 12 Relationship Problems, According to the Experts
For all the joy that romantic relationships bring us, it is needless to say that they are hard work. In the United States, it is estimated that one in two marriages ends in divorce.
Other data show that approximately 33% of people find it difficult to maintain their romantic relationships.
What makes sustaining a romantic relationship so difficult? A new study forthcoming in the journal Evolutionary Psychology has an answer.
A team of psychologists led by Menelaos Apostolou of the University of Nicosia in Greece found that 'fading enthusiasm,' 'long work hours,' and 'lack of personal time and space' are the three most common problems that prevent people from staying together.
They also estimate that only 30% of adults find it easy to sustain long-term romantic relationships.
To come to this conclusion, the researchers recruited 123 Greek adults to participate in a 40-minute survey interview. During the interview, participants discussed various difficulties they had in their romantic relationships.
The researchers kept track of the challenges mentioned by the participants, identifying 78 in total, and grouped them into 12 broad themes. Finally, they ranked these themes from most common to least common. Here's what they […]


text: Abstract：The device for measuring output error is simple in principle and with a low cost. It can meet most requirements of the measurement accuracy for the solar sensor. Its development is a sub-project of the project of the satellite dynamic simulator, as one of the important problems before the study and test of the satellite dynamic simulator, to measure the output error of the solar sensor. A design of the device is presented in this paper. It is based on the powerful ARM7 microchip controller. The high precision digital two-axis electric rotating platform is used to change the input angle. The ARM microchip controller is used to control the rotating angle and the rotating speed. A specific solar simulator is used as the light source of the solar sensor. The output angle of the solar sensor is transferred to the PC by the wireless URAT communication module. The error curve is obtained while comparing the changed angle of the rotating platform with the output angle from the solar sensor. The sources of the error of the device are reduced greatly. The main error sources are from the rotating platform and the solar simulator. The accuracy of the rotating platform reaches 0.001 25 mm per degree. The accuracy of the device can be in arcsec level if the surrounding is at a perfect state.


Vital evidence lost from Iraq's mass graves
14 May 2003
The desperate excavation of bodies from Iraq's mass graves by frantic relatives is destroying vital scientific evidence, experts are warning. The plea for the graves to be protected comes as the largest mass grave yet found was uncovered 50 miles south of Baghdad.
The grim finding near al-Hillah has yielded 3000 bodies, with a total of 10,000 people suspected to be buried there. The victims are thought to have been murdered during Saddam Hussein's brutal suppression of the Shia uprising after the 1991 Gulf War. Locals say they have identified about 1200 of the victims from identity cards or personal belongings.
But New-York based Human Rights Watch group has sharply criticised the US-led forces in Iraq for failing to protect the sites. They claim crucial evidence, vital for identification and for future war crimes tribunals, will be disturbed.
Spokeswoman Urmi Shah told New Scientist that verbal accounts of atrocities would not be enough to convict war crimes. She said legal trials related to the mass killings in the Balkans in the 1990s were clinched by the physical evidence.
Mistaken identity
Experts contacted by New Scientist agree that evidence will be lost unless the sites were policed to allow proper scientific exhumations.
Gordon Bacon, chief of staff at the International Commission on Missing Persons (ICMP) – an independent international organisation set up to identify bodies recovered in former Yugoslavia – said relatives tend to use circumstantial evidence such as clothing to identify their loved ones, but often these lead to incorrect identifications.
The organisation has set up a DNA database with samples from up to 43,000 relatives and more than 7000 victims. So far it has positively identified 2200 victims by matching DNA profiles. Bacon says DNA testing proved that nearly half of the "presumptive" identifications were wrong.
He argues that DNA profiling could also be used to identify bodies in Iraq, but that it must happen quickly. If a family believes they have already retrieved and re-buried the remains of their loved one, they will not then participate in DNA screening. This would leaves the real possibility that they re-buried the wrong person.
Ed Huffine, director of the ICMP's forensic sciences programme, adds that by removing bodies from the site, other crucial evidence might be lost, for example bullet shells or tyre track patterns. Also, if individual bodies are pulled out associations of bodies might be lost. If each village had its own section within the mass grave, this would indicate a systematic approach to the killing, says Huffine.
Resuming decay
Ian Hanson, a forensic archaeologist at the University of Bournemouth, UK, has worked in Bosnia and adds that even if the Iraq site is now cordoned off, damage to the exposed sections will continue.
"Once bodies have been buried, there is a certain amount of decomposition but then the environment stabilises," he says. The bacteria causing decomposition run out of oxygen, which helps preserves a lot of evidence. But when people have been digging and exposing the grave to the air, "you get a resumption of decay," he says.
Hanson says that in Bosnia, skin, facial features and even tattoos were preserved in this way helping identification. Organic materials such as paper documents and family photos can also be preserved in the centre of the grave.
Nonetheless, the experts unanimously agree that the distraught relatives' actions are completely understandable. "The families are going to need support. They're lived for 12 years, perhaps knowing their relatives might be buried a few kilometres away, but being too terrified to do anything about it," says Bacon. "They want closure."


Overview
twistor
Quick Reference
A generalization of the concept of a spinor that involves the use of complex numbers in an essential way. Twistors were invented by Roger Penrose in the hope that they would be a key concept in unifying the general theory of relativity and quantum mechanics. It has not done so yet, although some very intriguing relations have been established between twistors and noncommutative geometry, supergravity theory, superstring theory, and supersymmetry. Twistors have also proved useful for finding soliton solutions to gauge theories.

Dynamically Balanced Ovoid Sports Ball
A dynamically balanced inflatable ovoid sports ball (10) has a polar axis x, a first principal equatorial axis y and a second principal equatorial axis z. The axes x, y, z are mutually perpendicular and coincide at an origin o at the ball's centre of geometry. The ball (10) comprises an air inlet valve (11) to permit inflation thereof, and at least one additional mass element (12) adapted to counter-balance the mass of the valve (11). The air inlet valve (11) and each additional mass element (12) are arranged relative to one another such that the centre of mass of the ball (10) is substantially coincident with the origin o, and such that the difference between the average mass moment of inertia I yy of the ball (10) when rotated about the first principal equatorial axis y, and the average mass moment of inertia I zz of the ball (10) when rotated about the second principal equatorial axis z, is less than 3.46% of the value of I yy. .

I learned the following trick for memorizing the value of e from my colleague, Gene White. It never fails to impress calculus students (given a wide enough definition of "impress").
Start by carefully looking at this picture:
That's a 20 dollar bill, so memorize "2″ and put down the decimal point.
The picture on the bill is of Andrew Jackson. He was our seventh President, so put a "7″ after the decimal point to get 2.7.
Jackson was elected in 1828, so put down "1828″ next. Since there's a 2 in front of the decimal place, put "1828″ a second time. We're now up to 2.718281828.
Now look at the red square over Jackson's face. The diagonal creates two congruent right triangles with angle measures 45, 90, and 45. So, add on 459045 to get 2.718281828459045. And that's e to 15 places.
I'm open to suggestions on how to memorize more of the digits.

Products: ABAQUS/Standard ABAQUS/CAE
Warning: Except when used with truss or beam elements, ABAQUS/Standard does not form an exact material stiffness for this option. Therefore, the convergence can sometimes be slow.
The no compression and no tension elasticity models:
are used to modify the linear elasticity of the material so that compressive stress or tensile stress cannot be generated; and
can be used only in conjunction with an elasticity definition.
The modified elastic behavior is obtained by first solving for the principal stresses assuming linear elasticity and then setting the appropriate principal stress values to zero. The associated stiffness matrix components will also be set to zero. These models are not history dependent: the directions in which the principal stresses are set to zero are recalculated at every iteration.
Property module: material editor: MechanicalElasticityElastic: No compression or No tension
The no compression effect for a one-dimensional stress case such as a truss or a layer of a beam in a plane is illustrated in Figure 17.2.21. No compression and no tension definitions modify only the elastic response of the material. The overall behavior in a one-dimensional no compression elasticity model where the member is pulled, pushed, and then pulled again is as indicated in Figure 17.2.22.
Using no compression or no tension elasticity can make a model unstable: convergence difficulties may occur. Sometimes these difficulties can be overcome by overlaying each element that uses the no compression (or no tension) model with another element that uses a small value of Young's modulus (small in comparison with the Young's modulus of the element using modified elasticity). This technique creates a small "artificial" stiffness, which can stabilize the model.
No compression and no tension definitions can be used only in conjunction with an elasticity definition. The models can be used when the material behavior includes plasticity. See Combining material behaviors, Section 16.1.3, for more details.


Differences Between Mobile App and Web Performance Monitoring
By: AdamHass
 | May 1, 2023
Differences Between Mobile App and Web Performance Monitoring
Application Performance Monitoring, or Application Performance Management (APM), has become the de facto standard for providing better customer experiences and applications. APM allows you to observe the performance of your application including such valuable metrics as load time, errors, logs and transactions.
Mobile and web applications have similarities, but there are striking differences between the two. Mobile applications depend on the underlying frameworks provided by their operating system (iOS/Android). However, web applications, which have similar functionality to desktop applications, have a client–server architecture where the client (including the user interface and client-side logic) runs in a web browser.
Despite their differences and unique characteristics, mobile app performance is still related to web performance. The reason for this is that most mobile apps rely on servers to connect to APIs and download content. A poorly performing web application will likewise cause a related mobile app to perform poorly.
However, due to their defined differences, mobile and web applications have different metrics that we can monitor to provide a holistic overview of how our apps are performing.
What should you monitor in a mobile app?
When it comes to monitoring the performance of your mobile app, you should have a clear understanding of your goals and expectations. Some of the best metrics to watch include usage statistics, custom events, and crashes. However, having insight is not enough, you should also be able to take action and analyze trends.

Example AppLink.io usage stats module showing devices, carriers, versions and more
Usage statistics
Analyzing usage statistics will give you a better understanding of who your consumers are and their digital preferences. Getting breakdowns across devices, carriers, connection types, operating system, and app versions lets you know how your app is performing every day. Discover users experiencing poor app performance and diagnose the problems quickly.
Applink.io track custom event screenshot
Example AppLink.io SDK method tracking a custom event in iOS
Custom events
Any action that a user takes can be measured. Usually referred to in the context of in-app events, custom events give you the opportunity to track unique interactions. Once tracked, these events can provide an extra level of clarity about your app.
Applink.io crash screenshot
Example AppLink.io crash module showing crash details
App crashes
Nobody likes it when an app crashes. Tracking crash analytics as well as analyzing stack traces will help you quickly find and fix performance issues. Segmenting crashes by usage metrics can help uncover where a defect might be and get your app up and running fast.

Example AppLink.io triggers module showing a crash workflow
Triggered workflows
You can't always be staring at a screen monitoring your app. Everyone needs a coffee break or a day off. It's important to have an automated system that can trigger workflows and actions based on the good or bad experiences users are having in your app. Email and SMS alerts can notify you about a crash or other adverse event as soon as it happens.
Analyze trends
Having the data is the first step, but taking action from insight is a sign of maturity. Mobile APM can provide the foundation to build a decision supporting tool that will help leaders know the performance of their mobile apps, but more importantly, understand the data behind user behavior.
What should you monitor in a web application?
Like mobile apps, the goal behind performance monitoring of a web application should be utilizing the data to take action. Some of the key things that you should be monitoring include web requests and transactions, code-level performance, application dependencies, server monitoring, and log data.
Web requests and transactions
A basic function included in an APM solution should be the ability to review web requests and database transactions. Granted, most of this data can be obtained from a log, but it's important to understand what requests and transactions are taking place and how they are performing. Being able to identify and isolate slow incidents, can allow you to prioritize which ones to address first.

Code-level performance
They say, "The truth is in the code", and that is particularly true with application monitoring. An APM solution that can get you down to the code level can provide greater insights. Code-level performance profiling can help you understand what functions are being called and how long it takes to perform certain methods.
Application dependencies
A slow-performing web application can sometimes be attributed to a dependency within your application. Types of application dependencies can include databases, caching, message queues, web services, and HTTP APIs. A good application performance management system can track all of your application dependencies to help understand their performance.
ASPNET Performance App Dependency Redis Slow
Example shows application depending performance in Retrace
Server monitoring
Since the adoption of the cloud, most servers are created in virtualized environments and hosted in data centers. To keep tabs on your server, it's important to track server CPU and memory usage. In addition to being one of the primary factors associated with costs, heavy CPU usage can be an indicator of needing a larger server or adopting an auto-scaling strategy.

Log data
As a developer, whenever something went wrong, the first place I looked were the logs. The problem is that there are logs everywhere for everything. Database logs, server logs, operating system logs … you get it. A centralized logging solution is a key component for a APM solution.
Retrace log management for app monitoring
Example shows log monitoring features in Retrace
Putting it All Together
High-performance mobile apps depend on high-performance web applications. Both mobile and web apps have a joint responsibility of providing an exceptional experience for users. If you have a web application that has a dependant mobile app, it's important to keep both in mind when evaluating APM providers.
AppLink.io is a mobile app analytics tool and marketing platform that provides app statistics, metrics, tracking and monitoring capabilities.

text: Asemic writing is a form of writing with an open meaning. The term asemic means 'without specific semantic content'. Asemisch script can thus be read in a completely different ways by different readers. The language of the writer and that of the reader can be the same or different. In 'The Asemic Cabinet' examples are shown that come from the continuum between drawing and writing, between letter and doodle, between language and the unknown.

Dilworth Theater, Charlotte, N.C. 1939
Henderson County Public Library, Henderson, N.C.
The Dilworth Theater in Charlotte, N.C., was built for North Carolina Theatres, Inc., the company used by the Charlotte-based Wilby-Kincey theater chain for its North Carolina operations. The Dilworth was one of four Wilby-Kincey theaters operating in Charlotte. Located in the Piedmont region of the state, Charlotte had surpassed Wilmington as the state's largest city in 1910, and by 1940 had a population of more than 100,000, approximately thirty percent of which was African American. Charlotte was also the county seat of Mecklenburg County, the most populous county in North Carolina, with more than 150,000 residents. The Dilworth was located at 1609 South Boulevard in the neighborhood of the same name in South Charlotte.
In his book on Stillwell's drawings, Buildings as History: The Architecture of Erle Stillwell (Mitchell 2006, p. 132), William Mitchell describes the Dilworth as an exercise in "economical theater design".
Construction was concrete block, covered with stucco at the street front. The roof framing was steel bowstring trusses, clearly expressed in the front elevation. The Art-Deco design of the front was achieved solely by grooves in the stucco, forming pilasters on each side of the ticket lobby, a pattern of squares above, and two horizontal bands extending outward.
Plans for the Dilworth illustrate Stillwell's use of steel roof trusses, a construction technique common to movie theaters by the late 1930s. Such trusses enabled architects to design auditoriums capable of seating thousands of people and still provide unobstructed views of the screen from all parts of the house. Charlotte Herzog notes that in 1919, Thomas Lamb, architect of the Capitol Theater in New York City, employed a 170-foot steel truss, at that time the longest ever used in a building. (Herzog 1980, p. 85)
The Dilworth was the first North Carolina theater Stillwell had designed to be located outside of downtown and the first intended to be used as a secondrun houseshowing Hollywood films some months after their initial release in downtown theaters at cut-rate prices.
Front ElevationCharlotte Dilworth Theater, Courtesy of Henderson County Public Library, Henderson, N.C.
Dilworth was one of Charlotte's first "street-car" suburbs, planned in the 1890s and built out over the next four decades. The Dilworth Theater was approximately 1.5 miles from the center of downtown Charlotte.
The Dilworth had no mezzanine or balcony and little in the way of lobby or lounge amenities. Patrons bought their tickets from the box office in a recessed exterior lobby and entered the lobby, off of which were located toilets and a small cosmetic room for women. The shallow lobby led directly into the 600-seat auditorium. The screen was set into a small stage, but the Dilworth had no provisions for anything but the simplest forms of live entertainment (no fly loft or dressing rooms). The absence of a balcony suggests that the Dilworth was not designed to accommodate African Americans. Newspaper articles accompanying the opening of the theater make no mention of segregated spaces, and no "colored" admission prices are given in ads for the theater.
The Dilworth opened on Saturday, July 15, 1939. As had become customary, a dedication ceremony was held, attended by the mayor and open to the public. Much was made in newspaper coverage of the Dilworth Theater's contribution to the neighborhood, with local merchants taking out congratulatory ads and reminding readers of their convenient location in Dilworth. ("New Dilworth Theatre Opens, Filling Need for Large Section," Charlotte News, July 16, 1939, p. 10-A.)
The theater was destroyed in a fire in 1984.

- How to declare the end of a study
The end of the trial is normally defined as the last visit of the last participant, unless otherwise specified in the protocol. There are different processes to go through depending on whether you are undertaking a Clinical Trial of Investigational Medicinal Products (CTIMPs) or undertaking any other research. For all research studies other than CTIMPs, it is the responsibility of the Chief Investigator to notify the HRA and REC that gave a favourable opinion of the research, the Sponsor and R&D Department of the end of the study. The end of the study is defined as the final date or event specified in the protocol, not the completion of data analysis or publication of the results.
The Chief Investigator should complete a Declaration of the end of a study form available from NRES and send it to:
- Main REC that provided a favourable opinion;
- Research Sponsor: where Lancashire Teaching Hospitals NHS Foundation Trust is the Sponsor, please send documents to the Research Governance team;
- Please send copies of the End of Study form to the Research Access team
For a CTIMP the end of the clinical trial must be formally defined in the research protocol. It is a legal requirement of the current regulations that the competent authority (MHRA) and main REC are notified that the clinical trial has ended. For CTIMPs, this responsibility is often delegated by the Sponsor to the Chief Investigator for the clinical trial. The Chief Investigator (CI) is responsible for submitting the Clinical Trial Report to the MHRA no later than 1 year after the end of the trial.
- Funding Body Requirements
Funding bodies require a final report outlining how their funds have been used and the outcomes of the study.
- Dissemination of research findings
Health and social care research is conducted for the benefit of patients, users, care professionals, and the public in general. Therefore, all those pursuing health and social care research must open their work to critical review through the accepted scientific and professional channels. The obvious route to inform the research community is through publication in scientific journals. However dissemination strategies can also include: presentation at local, regional and national conferences and meetings; informing research participants of research findings and informing service users of findings.
- Archiving of Research Documents
Following the close of a trial it is necessary to archive all trial related documentation to ensure that all study documentation are:
- Stored correctly and confidentiality maintained;
- Not passed on without the appropriate consent;
- Accessed in-line with Trust policies and procedures;
- Only used for the defined purpose;
and to ensure:
- Patient safety in using and recording information;
- Up-to-date information is stored;
- Staff awareness of responsibilities and accountability;
- Information is accessible when required;
Storage of personal data is subject to the Data Protection Act 1998 and, in clinical trials, the applicable elements of the UK Clinical Trial Regulations.
Please contact the Centre for Health Research and Innovation regarding the procedure for archiving all study documents on ALL research studies that are sponsored by or hosted by Lancashire Teaching Hospitals NHS Foundation Trust. The length of time for archiving is dependent upon each individual protocol and/or guidance from the commercial sponsor.

Driver Knowledge Tests Menu
A turn signal that keeps flashing after a turn is very likely to: A turn signal that keeps flashing after a turn is very likely to:
 - A. Confuse other drivers and cause them to turn into your path.
 - B. Damage the electrical system.
 - C. Keep other drivers from seeing your brake light.
 The correct answer is A
 Correct. If you are indicating, drivers may think you are turning and might pull out in front of you.
Motorbike indicators
Newer bikes sometimes have self-cancelling indicators. They can work on the change in angle of the bike, a timer that turns them off after a pre-defined number of seconds, or the change in the speed differential between the front and rear wheel.
However, you should get used to doing it yourself otherwise you might get on another motorbike that doesn't have self-cancelling indicators and you'll forget and cause a problem for yourself when another vehicle pulls out in front of you thinking that you are turning.
Similarly, at the rear, there are integrated taillights and indicators available for some bikes.
Modern indicators have LEDs rather than bulbs.
Indicators come in five main types:
 1. Flush-mounted - these fit in holes in your faring and sit flush (or almost flush) with the surface
 2. Stalk - these sit out from the bike on stalks
 3. Surface-mounted - these indicators sit on the surface and can be used to cover indicator mounting holes on some models of bike.
 4. Numberplate-mounted - these indicators sit either side of your numberplate.
 5. Mirror-mounted - it's possible to get indicators integrated into your mirrors which can clean up the profile of your bike.


If the regex cache
 grows to larger than this number of entries, the systems attempts to
 purge some of the older entries.
* When a search process is allowed to run more than one search, the search
 process can cache compiled regex artifacts.
* Normally the "idle_process_cache_search count" and the
 "idle_process_cache_timeout" settings will keep the regex cache a
 reasonable size. This setting is to prevent the cache from growing

 if "max_searches_per_process" is set to 0 or 1.
* NOTE: A search can run longer than the value set for "max_time_per_process"
 without being terminated. This setting ONLY prevents the process from
 being used to run additional searches after the maximum time is reached.
* Default: 300 (5 minutes)
process_max_age = <number>

Technote (FAQ)
If an individual installs multiple Rational products in the same Eclipse shell, and if the floating license for one of them is not available, can the other products, or the base Eclipse, or both another product and the base Eclipse be used?
No, all licenses need to be available at product launch for both Eclipse and the products to be used. This document explains the basic current behavior, along with the workaround if the user prefers the old behavior (that is, running a disabled product without a license).
There is a common misunderstanding about the licensing behavior when multiple products are installed into the same Eclipse shell. It is wrongly believed that only when a product is used will it consume a license.
For example, a customer reported when Rational Software Architect v7.0 and Rational Data Architect v7.0 are installed in the same shell, they see licensing errors when starting Rational Data Architect 7.0 by clicking on the shortcut to run Rational Data Architect v7.0. The customer is running Rational Software Architect v7.0 and Rational Data Architect v7.0 and does not have a license for Rational Software Architect. So Rational Software Architect plugins will not run. This is by design for all products and why there is licensing enforcement in the first place. There are multiple reasons it could be requiring a Software Architect license, such as startup plugins, builders, etc. It is incorrect to believe that a product in a shell sharing situation can be completely separate and you cannot load it by loading "knowing" plugins which are product specific. So the Rational Software Architect license failures should be no surprise.
The key to this is the following statement by the customer, "Since no Rational Software Architect specific functionality is apparently being invoked this surprised me." This implies the assumption that Rational Software Architect functionality is somehow separate enough and partitioned to specific perspectives and views. This is a false assumption and is not how Eclipse works. Eclipse loads plugins as needed. If a request for a Software Architect plugin happens underneath the covers (for example Rational Data Architect having an optional plugin dependency on Rational Software Architect to provide enhanced function and Data Architect proceeding to request that plugin get loaded since it was installed) then a Rational Software Architect license will get consumed.
The particular set of errors in version 7.0 prompted a change to the startup behavior in products such as Rational Software Architect v7.5 and Rational Performance Tester v8.0, based on the following four points:
1. If there is no license for one product in the shell then the choice is to remove the product or license it.
2. It is impossible to have two products sharing the same shell and being able to know that licensed content will not be loaded and what will.
3. IMPORTANT: Customers can install two products into the same shell and only when a product is used will it consume a license. This is correct in the sense that only when a product is used will it consume a license. It is incorrect to think running one product in the shell will not consume a license of the other product in the same shell, because once products are installed in the same shell, there is no guarantee it will not consume a license because what action in the user interface or build or gesture could trigger a license to be needed cannot be guaranteed. Shell sharing products are intimately connected. It will require all the products to change their architecture in order to enable this behavior. That kind of architecture will remove the seamless nature of the product integrations that now occur since it requires that products be logically separate and not integrate with each other.
4. Shell sharing products are basically running as a single unified product from the perspective of Eclipse. In order to not have continual errors and random dialogs asking for licenses to pop up all the required licenses to run, the content in that shell needs to be available upon product start.
Thus, in products releases since v7.0, the launch of a product, including Eclipse, will be blocked if it cannot acquire a license for all the products running in the shell.
Most of the issues around the added complexity are related to customers not wanting to consume a license when two products are installed together. The products are not architected for that scenario. They are architected to install two products together to get the combined function of the two products in a seamless scenario. Therefore you need two licenses for two products running in the same shell.
Licensing block workaround
Note: this is not recommended; use it only as last resort.
A product such as Rational Software Architect 7.5 or Rational Performance Tester v8.0 will block the launch of a product if it cannot acquire a license for all the products running in the shell. To work around this blocking behavior:
Add a line to existing \configuration\config.ini:
These changes were made
In the presence of this system property, the "License Cannot Be Found" error dialog now provides an "Ignore" button which will allow users to continue execution of the product.
Licensed plugins will still fail to load and potentially display further error dialogs (that is, if they load sometime after startup).
There is now a "Done" button in the "Manage Licenses" dialog (when there is a license error and where Exit Workbench formerly was the only choice):
There now is a "Manage Licenses" toolbar button with an error icon when executing in unlicensed mode (similar to Manage Licenses toolbar button with warning icon added during last 14 days of a trial license, except this uses an error icon):

P.E. Central Lesson Plan: Want Ad: Healthy Eater
Purpose of Activity:
The purpose of this lesson is for students to understand the differences between healthy and unhealthy eating habits and what steps they need to take in order to make healthy eating choices.
Suggested Grade Level:
A newspaper with want ads; Construction Paper
Description of Idea
Begin the lesson with a discussion about eating habits. This may include a discussion of the Food Guide Pyramid, Dietary Guidelines, etc. Have the students give examples of healthy and unhealthy eating habits.
Example: Healthy Eating Habit = Eating fruitÂ
Unhealthy Eating Habit = Drinking soft drinks
NOTE: Using a transparency with some examples that you have generated may be helpful.
Next, introduce the concept of a Want Ad.Â
What is a want ad?Â
What does "ad" stand for?
Let the students read want ads from actual newspapers. Have the students discuss qualities the companies were looking for in the people they wanted to hire.Â
Students will then write their own 'want ads for a healthy eater'. The want ads should list specific characteristics of a healthy eater.
TIP: Encourage students to think of five specific ways they could help themselves become healthy eaters, and then plug those five things into the want ad. EX: Drink a glass of milk with every meal.
After the students have made their want ads, ask the students to share their want ads for healthy eaters with the rest of the class. Have the class discuss which characteristics might be the most important in becoming a healthy eater.
Give the students a chart in which they will fill in the characteristics they included on their want ads. The students will take the chart home and fill in a smiley face for the days in which they followed through on the healthy eating habits listed.

, etc. For example, if a bruk with løpenummer 10 was subdivided, the old bruk would be numbered 10a, and the new bruk that was created would be numbered 10b. The 1838 matrikkel also introduced a new way of measuring the real estate tax, using the skylddaler. 1 skylddaler was set equal to 400 speciedaler (an old currency), and 1 skylddaler was divided into 5 ort or 120 skilling so that an accurate tax could be assessed on each farm. The 1838 matrikkel contained both the old and the new numbering system for each farm, and thus serves as a cross-index between the new and the old numbering system.
The matrikkel from 1886 also contains such a cross index. The 1886 matrikkel once again changed the numbering system: each farm was assigned a gårdsnummer (farm number)and a bruksnummer (bruk number). This matrikkel has been made available on the Internet by the
Registreringssentral for Historiske Data (RHD) at the University of Tromsø (in Norwegian only). In addition, RHD has scanned in a
sample page from the 1886 matrikkel. On the top left hand side of that page you can see how the 1886 matrikkel cross references the new gårdsnummer and bruksnummer with the old matrikkelnummer and løpenummer:
(Gaards-No. = Farm number, Brugs-No. = Bruk number, Tidligere= Earlier/Prior, Matr. No. = Matrikkel Number, Løbe-No.= Løpenummer, and Gaardens Navn = The name of the farm)
The 1886 matrikkel also changed the way the tax was calculated. Instead of using skylddaler, the 1886 matrikkel set the total real estate tax for all farms in Norway equal to 500,000 skyldmark, and set 1 skyldmark equal to 100 øre. The value of each farm was then determined in terms of skyldmark.
The husmann and the husmannsplass
As I mentioned earlier, a farmer who owned his own farm, i.e., a selveier, did not have to pay any landskyld, but he did have to pay real estate property taxes. A leilending, on the other hand, did not have to pay any real estate property taxes, but instead had to pay landskyld to the jorddrotte (the owner of the farm). There was one person, however, who paid neither landskyld nor real estate property taxes, and that was the husmann - a person who rented a husmannsplass.
The best way to define a husmann is by reference to the matrikkel. A husmann was a person who leased a small cottage on someone else's farm, where the small cottage did not have its own matrikkel nummer i.e., it was not assessed separately from the farm for real estate tax purposes. The husmann could rent just a small cottage without any land, in which case he was referred to as a husmann uten jord (a husmann without land), or he could rent a small cottage with a small plot of land, in which case he was referred to as a husmann med jord (a husmann with land). In eastern Norway it was common for a husmann to pay his rent by providing a few hours of labor (arbeid) each month to the farmer. This type of husmann was therefore called a arbeidshusmann. On the west coast of Norway, on the other hand, it was common for a husmann to pay his rent in cash, and this type of husmann was called a bygselshusmann, and the place he rented was called a bygselsplass. Frequently the bygselshusmann on the west coast of Norway was a shoemaker or perhaps a tailor, whose occupation gave him a source of income with which to pay rent for his little bygselsplass. (Along the coast of Norway you can also find references to a strandsitter. This was a husmann who earned his living from the sea and who rented a cottage down by the shoreline).
Although a typical husmann was not wealthy, this did not necessarily mean that he was worse off than a farmer who owned his own farm. As the historian Hans Try has pointed out:
There were large differences both regionally and also within a community. A husmannsplass could be much larger than some of the smaller farms in a community. In fact, a husmann could even have more farm animals than the farmer from whom he was leasing the husmannsplass. This could be the case if the husmannsplass lay at the edge of the farm where the husmann had easy access to grazing land that was owned and used in common by the various local farms. As for regional differences, in Søndeled in Nedenes the average farm in 1875 had only 2.9 cows, while in Dovre in the same year the average husmannsplass had 4.2 cows. For the entire country, however, the average farm had 6.7 cows, while the average husmannsplass had only 2.1 cows.
The Inderst or Losjerende One other term you may find as you search through old Norwegian records is Inderst or Innerst. This term was used to refer to a lodger - a tenant who rented a room or a bed in the home of a leilending or a husmann, but who did not receive board, i.e., not room and board, but room only. You may also see this person referred to as a losjerende or logerende (a lodger). The inderst could be a seasonal worker on the farm or could be self-employed as a tailor, shoe-maker, etc.
Conclusion Reading old Norwegian census records, probate records,and real estate records requires us to have some background information about how the ownership of farms in Norway changed during the centuries. Genealogy is not only about collecting as many names and dates as possible, but also learning more about how our ancestors lived. I hope this article has provided some information that helps you in your quest to learn more about your Norwegian ancestors.

Take the 2-minute tour ×
I have to read and write binary data, where each element of data:
 - size = 2 bytes (16 bit)
 - encoding = signed 2's complement
 - endiannes = big or little (must be selectable)
Is it possible without using any external module? If yes,
 1. How to read such data from a binary file using read() into an array L of integers?
 2. How to write array of integers L into a binary file using write()?

Have you looked at Python's struct module? – Kai Feb 17 '11 at 15:30
I'd say the struct module would be the best place to start – Exelian Feb 17 '11 at 15:31
Using struct would be quite inefficient, though, because you would have to unpack the values one by one. – Sven Marnach Feb 17 '11 at 15:34
_USER_ Marnach: Have you measured that? – S.Lott Feb 17 '11 at 15:47
_USER_.Lott: Yes, while answering this question last year. I don't remember the exact figures. – Sven Marnach Feb 17 '11 at 15:52

I think you are best off using the array module. It stores data in system byte order by default, but you can use array.byteswap() to convert between byte orders, and you can use sys.byteorder to query the system byte order. Example:
# Create an array of 16-bit signed integers
a = array.array("h", range(10))
# Write to file in big endian order
if sys.byteorder == "little":
with open("data", "wb") as f:
# Read from file again
b = array.array("h")
with open("data", "rb") as f:
 b.fromfile(f, 10)
if sys.byteorder == "little":
share|improve this answer
More generally, seeing that the OP in effect wants a file_byteorder arg, use if sys.byteorder!= file_byteorder: b.byteswap() in both input and output. – John Machin Feb 17 '11 at 20:54
_USER_: That's why I wrote "example" above :) – Sven Marnach Feb 17 '11 at 21:04
Consider using
struct.unpack(byteorder + str(len(rawbytes) // 2) + "h", rawbytes)
where byteorder is '<' or '>' as desired, and similarly for packing. Note: I'm not claiming that this is faster than the array way, but I do note that the array way sometimes needs an additional byteswap step.
share|improve this answer
The struct way always needs an additional unpack() step. The main difference is that you will end up with a Python list, while you get an array when using array.fromfile(). – Sven Marnach Feb 20 '11 at 11:12
from array import array
# Edit:
from sys import byteorder as system_endian # thanks, Sven!
# Sigh...
from os import stat
def read_file(filename, endian):
 count = stat(filename).st_size / 2
 with file(filename, 'rb') as f:
 result = array('h')
 result.fromfile(f, count)
 if endian!= system_endian: result.byteswap()
 return result
share|improve this answer
array.fromfile() always takes two parameters. – Sven Marnach Feb 17 '11 at 15:55
Ugh. That's utterly inconvenient. :( – Karl Knechtel Feb 17 '11 at 16:01

Using Liquibase with SQLite
SQlite is a relational database management system that implements a small, fast, and self-contained embedded SQL database engine.
Supported Versions
 - 3.X
Before using Liquibase and SQLite, ensure you have completed the following:
Driver Information
To use Liquibase and SQLite, you must install the JDBC driver:
 1. Download the sqlite-jdbc-.jar file for a version of SQLite that is supported by Liquibase. You can also download this jar from Maven's central repository.
 2. Place the sqlite-jdbc-.jar file in the liquibase/lib directory.
 3. Note: If you put the sqlite-jdbc-.jar file in any other directory, specify the path to it in the file: classpath:../path_to_drivers/sqlite-jdbc-.jar.
 4. Open your file and specify the driver value in it:
 5. driver: org.sqlite.JDBC
If you use Maven, add the following XML fragments to your Maven pom.xml file:
Maven will use this information to download the SQLite JDBC library from Maven's central repository into your local repository.
Testing Your Connection
For Liquibase and SQLite to work, you need to:
 1. Ensure your SQLite database is configured. You can use sqlite3 commands like.databases and.show to check the status of the database.
 2. Specify the database URL in your file:
 3. url: jdbc:sqlite:example.db
 4. Create a changelog file called dbchangelog (.xml,.sql,.json, or.yaml) in your project directory and add a changeset to it.
 1. Specify your changelog in the file. It should look like this:
 2. changeLogFile: dbchangelog.xml
 url: jdbc:sqlite:example.db
 driver: org.sqlite.JDBC
 Note: By default, SQLite databases do not require authentication, so the username and password attributes do not have to be specified. For more information, see SQLite User Authentication.
 3. Run the status command to see whether the connection is successful. This will create a database called example.db in your project folder if it does not already exist.
 4. liquibase --changeLogFile=dbchangelog.xml status
 Note: If you did not specify any properties in your file, they must be passed into the command line as attributes.
 5. You can preview any database changes you want to make using the updateSQL command, which will compare your changelog to your database and display the SQL needed to add your undeployed changesets. Then run your first database update with the update command.
 6. liquibase --changeLogFile=dbchangelog.xml updateSQL
 liquibase --changeLogFile=dbchangelog.xml update
 After your first update, you will see a new table along with the DATABASECHANGELOG and DATABASECHANGELOGLOCK tables added to the database:
 - DATABASECHANGELOG table. This table keeps a record of all the changesets that were deployed. When you deploy, the changesets in the changelog are compared with the DATABASECHANGELOG tracking table, and only the new changesets that were not found in the DATABASECHANGELOG will be deployed.
 - DATABASECHANGELOGLOCK table. This table is used internally by Liquibase to manage access to the DATABASECHANGELOG table during deployment and ensure only one instance of Liquibase is updating the database at a time, whether that is creating, updating, or deleting changes.

The use and teaching of discourse markers in Hong Kong: students' production and teachers' perspectives
Fung, Loretta Po-yin (2003) The use and teaching of discourse markers in Hong Kong: students' production and teachers' perspectives. PhD thesis, University of Nottingham.
The present study attempts to investigate discourse markers from a functional and attitudinal perspective. Based on the pedagogical sub-corpus from CANCODE and the audio-recordings of class discussion of 49 secondary pupils in Hong Kong, Part I explores the roles discourse markers play in spoken discourse on a contextual basis and compares the different use of discourse markers by British and Hong Kong speakers of English using quantitative and qualitative methods. Discourse markers are found to serve as useful contextual coordinates to structure and organise speech on interpersonal (marking shared knowledge, attitudes and responses), referential (indicating textual relationships such as cause, contrast, coordination, digression, consequence, etc. ), structural (summarising opinions, marking sequence, opening and closing of topics, transition and continuation of topics) and cognitive (denoting hesitation and thinking process, marking reformulation, selfcorrection or elaboration, and assessing the listener's knowledge about the utterances) realms, bearing a probabilistic relationship with the various role(s) on a multifunctional dimension in pedagogic discourse. Functionally, non-native speakers are found to display a highly restricted use of discourse markers, especially those interactive ones (e.g. initial and, yeah, you know, ), whereas native speakers tend to use discourse markers more for a variety of pragmatic functions.

For fixing laboratory flasks in suspension baskets
Set consisting of 5 pcs. laboratory flask holders à 155 mm and 3 pcs. laboratory flask holders à 215 mm; stainless steel. Scope of delivery: 8 pieces.
In order to carry out smooth sample preparation, the appropriate conditions for laboratory work must be created. Samples should be homogenised, extracted or degassed quickly and reliably for subsequent analysis in laboratory vessels of various shapes and sizes.For this challenge, BANDELIN has developed practical holders for fixing laboratory flasks in suspension baskets for SONOREX ultrasonic baths. The holders guarantee the stability of the laboratory flasks during sonication. At the same time, they ensure optimum coupling of the samples to the contact liquid and thus low-loss ultrasound transmission into the sample to be sonicated.
The laboratory flask holders can be mounted quickly and easily as longitudinal and transverse dividers at any position on the basket rim by means of small hooks. The compartment size can be individually adjusted according to the flask shape and size (10 250 ml) and can be changed again in no time at all.
Without any effort or additional tools, the laboratory flasks can be inserted precisely so that sample preparation with ultrasound is safe and effective.
In order to ensure that the SONOREX ultrasonic bath continues to be filled at the optimum level and to avoid flooding of the laboratory flasks, we recommend the handle adjustment GV 10.

Aeromedical Causes of Accident Errors among Pilots and Aircraft Engineers in Nigeria
rrors in the aviation industry are considered among experts as major factors that cause accidents and incidents. This paper examines the aeromedical factors that account for incident or accident errors among pilots and aircraft engineers in Nigeria. The paper made use of data collected by administering questionnaires to randomly sampled respondents. A total of 300 questionnaires were administered to both pilots and aircraft engineers. Data were analysed using a combination of factor and multiple regression analyses. The extracted variables after factor rotation show that general health (78.20%) is the most significant cause of errors among air craft engineers. As regards pilots, disorientation (79.20%) was found as the most critical aeromedical cause of errors. The results of the multiple regression analysis show R = 0.651 for aircraft engineers and R = 0.607 for pilots. These findings reveal that aviation accidents and incidents arising from errors could be traceable to these aeromedical factors. The paper recommends that stringent enforcement of aeromedical conditions should be added to the licensing and recertification guidelines for aviation professionals so that accidents and incidents traceable to errors can be reduced to the barest minimum in the Nigeria aviation industry.

Numerical Simulation of Zeolite- and V-Based SCR Catalytic Converters
A numerical model describing the ammonia based SCR process of NOX on zeolite catalysts is presented. The model is able to simulate coated and extruded monoliths. The development of the reaction kinetics is based on a study which compares the activity of zeolite and vanadium based catalysts. This study was conducted in a microreactor loaded with washcoat powder and with crushed coated monoliths. A model for the SCR reaction kinetics on zeolite catalysts is presented. After the parameterization of the reaction mechanism the reaction kinetics were coupled with models for heat and mass transport. The model is validated with laboratory data and engine test bench measurement data over washcoated monolith catalysts. A numerical simulation study is presented, aiming to reveal the differences between zeolite and vanadium based SCR catalysts.


text: The application of the time reversal method in pipe-like structures based on finite element method (FEM) is investigated. A steel pipe model measuring 70 mm × 3.5 mm is used to analyze the reflection coefficient of the (0,2) mode with the time reversal process. Simulation results show that the time reversal array method is beneficial to the improvement of the signal-to-noise ratio of a guided wave inspection system. As the intercepting window is widened, more energy is included in re-emitted signals, which leads to a large reflection coefficient of the (0,2) mode. In parallel, a circumferential locating method based on the time reversal method is described. The time reversal process used for guided wave inspection leads to the temporal and spatial focusing. When the time reversal signals are re-emitted, the angular profile obtained at the axial location of the defect can be used to determine the circumferential location of the defect. Except for a pipe with one defect, the circumferential locating method has been verified on another pipe model with two defects. Meanwhile, the elements number of the time reversal array has been discussed for enhancing the discrimination of the defect circumferential location.
