Cultural Competency
To help students develop cultural competency, a CITE co-curricular learning activity can include reflection on the students' cultural worldview and their understanding of other worldviews and may encourage students to examine how different cultural perspectives are valuable to the development of community. It may teach and require students to demonstrate specific skills necessary to successfully navigate cultural contexts that are unfamiliar to them. Here are some practical ways to incorporate this student learning outcome:
 - Before planning a health fair for a local community, students are required to talk to community members about their attitudes and awareness of specific health issues and about health challenges that are unique to their community.
 - While on a learning abroad trip, students are given opportunities to proactively engage with natives of the community and are required to incorporate these interactions in a final paper that discusses art and culture in the region.
CITE has developed the Cultural Competency Rubric Templatebased on the AAC&U's Problem Solving VALUE Rubric, to assist program leaders in developing their own rubrics for this learning outcome. You are welcome to draw on the linked editable file while designing a rubric for your program.

Under the premise of making a backup, pay attention to the following points when using the software:
1. During the use of the light painting software, pay attention to the orderly storage of the light painting files. It is best not to place the non-program files such as Gerber files, raster files, temporary files, etc. in the software installation directory, so as to avoid deleting the program files by mistake. Destroy the operation of the software.
2. The software can run on the DOS operating system or in the DOS window mode of WINDWOS'9X. When reading a file, you should enter the full path and file name. Once the setting parameters of the software are set, do not change them easily, so as not to affect the accuracy of the raster file and the accuracy of the drawn film.
3. Before performing the typesetting operation of the file, the mouse driver should be loaded to use the mouse to perform the typesetting operation. When there are too few typographic layers and not enough to fill the entire film, you can save the processed files first, in order to prepare the next tune with other files. When compiling and saving, try to choose in the DOS window mode of WINDWOS'9X, so as to avoid the crash caused by the lack of DOS memory management in the DOS environment. Try to follow the order of first left and right, first up and down, and it is convenient to cut the film on the film when you are dissatisfied with the whole film.
4. The completion of rasterization should be done in DOS environment, making full use of the single task process of DOS, and avoiding the choice in WINDWOS'9X DOS window mode.
5. The partition of the storage raster file should ensure the largest possible free space on the hard disk, and often use the disk defragmentation program to organize the hard disk to reduce the generation of file fragments. After the rasterization is completed, it should be repeatedly previewed several times to ensure that the raster file is not broken, no gaps, etc., and then output.
6. Enter the Gerber file processing before the light painting system, fully utilize the light painting assistant software to process the extra elements and reduce the amount of file data. The parts that need to be filled are filled with horizontal horizontal software as much as possible for complex elements (such as arcs, custom pads, etc.), which should be carefully modified and edited in the light painting assistant software. Through the above steps, the error rate of the raster file can be reduced, and the time required for rasterization is greatly reduced.
7. The old version of the light painting software V2.0---V2.8, only supports English (English), leading zero (Leading), integer decimal places (2, 3), absolute coordinates (Absolute) The Gerber format of the data structure is usually based on the V2001 extended Gerber (Extend Gerber) format (usually used when the amount of data is large) and the MDA (MDA Auto plot) format (usually used when the amount of data is small). The new version of the light painting software does not have this problem.
8. The software installation adopts encryption means, so do not easily change the hardware device of the host computer to avoid the software verification error and cannot run. Please save the software installation disk to restore it when the software is damaged.

UNESCO International Literacy day 2012 Theme
Literacy is important for then growth and development of society. The society can become healthy and Wealthy with literacy. UNESCO (United Nations Educational Scientific and Cultural Organization) has initiated for the observance of international literacy day.
Date of International Literacy day:
The first international literacy day was observed in the year 1965. Every year international literacy day shall be observed on the 8th day September. UNESCO is taking up then initiation of celebration of international literacy day across the globe.
Need for literacy and observation of international literacy day:
Nearly one in every six people is still illiterate. Among these two thirds are women. Nearly 80 crore adults are still illiterate in the world. There are so many children are out of school during their young age. It is observed that poverty and ill health is related to illiteracy in then world. Literacy can improve the quality of life among the human beings. One can have better sanitation and health with literacy. Educating adult illiterate and bringing the children to schools at the young age are the main agenda for organizing the international literacy day. Literate adults can know the need of education and can send their children in pursuing education. Literacy can uplift people from poverty. UNESCO supports its member states in planning and implementation of program for the improvement of literacy rates in the respective sites.

I posted earlier about a scenario-based conversation simulation that I created as part of a recent course. If you want to read about the simulation itself without the XML and AS code-ish techno garble stuff, click here to visit my previous post. You can also view the course itself within my online portfolio by clicking here.
In this post, I focus on how I used XML and AS3 to dynamically generate dialogs and interactions for the simulation as well as control of the branching logic. My goal is to give an overview of the technical structure, without getting too terribly deep in – however, this post is definitely aimed at people who develop using Flash, XML, and AS.
General Design Structure
I like to use Flash to design elements of my activity interfaces, but control almost everything else using AS3 and XML. This lets me take advantage of Flash's friendlier design environment while still keeping the logic of my activities flexible.
So, for example, for the dialog boxes in this simulation, I created a MovieClip in Flash with a background, text fields for the dialog title and content, and a Continue button.
Less than thrilling, right? However, with some XML and AS, it'll magically become more exciting.
In the XML for this section, I created an element for each dialog box and interaction. Here's an example of the XML for a standard dialog box:
Within the dialogBox element, the child elements id and launchNext define the simulation branching. The child elements title and description define the text that appears in the dialog box.
When the SWF for the course first loads, the AS for the loan officer simulation section loads and cycles through the XML to create all of the dialog boxes and interactions using the given elements and data. Each dialogBox element results in an AS generated dialog box, using my Flash created MovieClip. Same for the interactions and several other simulation objects.
For example, the AS uses the XML dialogBox element from the sample above to create the following dialog box in the course:
Clicking the Continue button moves the user to the dialog box or interaction defined in the launchNext element – in this case, the dialog box with the id Interface_Dialog.
I created interactions in the course using a similar framework, but the interaction elements contain more child elements, since user choices affect both the course variables and the simulation path in various ways.
Here's an example of the XML for an interaction :
For some options, I also added elements to introduce special variables to trigger events later in the scenario and other elements that would remove or add options to future interactions (these aren't shown in the example above).
The XML above results in the following interface in the loaded SWF:
Because the AS dynamically generates all of the dialog boxes and interactions when the SWF loads, I could happily edit, create, or remove dialog boxes and interactions to my heart's content, without ever editing the AS or republishing the SWF, except in the moments where I wanted to the logic of the simulation to move beyond simple branching (more on that later).
Planning Flow Charts
To plan the logic of the simulation, I created flow charts for each section. Here is an example of a flow chart, from the Promotion and Sales section of the simulation (click to view a larger version):
In total, there were five sections in this simulation: Promotion and Sales, Evaluation, Approval, Disbursement, and Collections and Recovery.
Beyond Simple Branching
I mentioned above that there were times that I wanted to move beyond simple branching, so the launchNext element alone wasn't adequate. I had a couple of additional XML elements that the AS would watch for and use to override the default launchNext. For example, in dialogBox element below, the checkPotentialEnds element triggers the AS to evaluate whether or not any of the key indicator variables had fallen low enough that the user simulation should end. If so, the user would be brought to one of several potential simulation ends, instead of being brought to the dialog box with id Application_Redo_Dialog.
Similarly, at the beginning of some sections, I wanted to vary the opening dialog that the user would see based on his or her past decisions. In the XML below, the variableLogic element would trigger the AS to evaluate the past decisions to decide which opening dialog to launch for the Application section.
If you want to take a closer look at how all of this looks in action, you can view the course within my online portfolio by clicking here.

Centipeda cunninghamii is commonly known as Old man weed, being the literal translation of its Koori name Gukwonderuk. It is a plant known to indigenous Australians for its medicinal properties, and grows along the Murray river, or generally anywhere there is water, especially low lying or swampy areas. It can be identified by its unique shaped leaf, and its pungent scent, which is pine like and minty. The names Common Sneezeweed and Scent Weed, which were given by European settlers, are increasingly falling out of use.
Old Man Weed was commonly used to treat hair loss and skin irritations, but the traditional belief holds that it is good for treating "just about anything". Traditional methods of use most commonly involve binding leaves of the plant directly to the forehead or other parts of the body, so that body heat may release the plants oils which are then absorbed into the skin. It may also be taken orally, sometimes mixing it with emu fat or boiling/soaking it in water to create a tea. In cases of oral ingestion, traditional medicinal authorities have cautioned to carefully regulate the dosage as the plant may be toxic if taken in large amounts.
More recently, the extract of the plant has been patented and is claimed to be effective in the treatment of various skin disorders including the relief of itching and dry skin from psoriasis, as well as having antiinflammatory, antiallergenic, sunscreen and cell renewal properties.

Halfway Home – The Rehabilitation of New Zealand Second World War POWs in Britain
While suffering through monotony and deprivations, New Zealand Second World War POWs mentally escaped their confines by imagining their eventual return home. They envisaged returning to a world free from the woes of captivity and war. This paper examines their rehabilitation in Britain. While Britain was not New Zealand, the prisoners expected it to conform to their idealised version of home. However, this paper argues prisoners experienced difficulties during their rehabilitation, and they were destabilised when confronted with the continued presence of the war and captivity.

The gas sensitive material used in MQ-6 gas sensor is SnO2, which is of lower electrical conductivity in clean air.
When there is combustible gas in the environment where sensor resides, the electrical conductivity of the sensor increases with the increase of the combustible gas concentration in the air.
The change of electrical conductivity can be converted to the output signal corresponding to that of the gas concentration by using a simple circuit.
The sensitivity of MQ-6 gas sensor to propane, butane and liquefied petroleum gas is quite high, and the natural gas can also be well detected.
This sensor can detect a variety of combustible gases, making it a low-cost sensor for a variety of applications.

Why is the cum used? I interpreted the English sentence as: The Germans along with their sons and daughters are fleeing by means of
horses and wagons. So doesn't that make the equis et carris
ablatives of means, which according to D'Ooge should not have a cum preceding them. So shouldn't the second cum be absent in the snetence?
One explanation I could think of is that the horses and wagons are also ablatives of accompaniment, but why not means?
Could someone please help me out here.

A cost-effective electric vehicle charging method designed for residential homes with renewable energy
Lie, TT; Liang, X; Haque, MH
MetadataShow full metadata
Most of the electrical infrastructure in use around the world today is decades old, and may be illsuited to widespread proliferation of personal Electric Vehicles (EVs) whose charging requirements will place increasing strain on grid demand. In order to reduce the pressure on the grid and taking benefits of off peak charging, this paper presents a smart and cost effective EV charging methodology for residential homes equipped with renewable energy resources such as Photovoltaic (PV) panels and battery. The proposed method ensures slower battery degradation and prevents overcharging. The performance of the proposed algorithm is verified by conducting simulation studies utilizing running data of Nissan Altra. From the simulation study results, the algorithm is shown to be effective and feasible which minimizes not only the charging cost but also can shift the charging time from peak value to off-peak time.

The total energy is:
EKinetic + EPotential = Etotal
1) 1/2*mv2 + 1/2*kxmax2 = Etotal
When the spring is fully compress the kinetic energy is zero and so the potential energy is equal to the total energy:
2) 1/2*kxmax2 = Etotal
When the spring is not compress at all, the potential energy is zero, which results in the kinetic energy being a maximum, which requires the velocity to be a maximum as well.
The velocitiy at any given point, such as in part d) can be solved by evaluating equation 2) to get the total energy, algebraically solving equation 1) for velocity, v. Once the velocity is known the knietic energy can be directly evaluated.

Street fair
From Wikipedia, the free encyclopedia
Jump to: navigation, search
A New York City street fair.
A street fair is a fair that celebrates the character of a neighborhood. As its name suggests, it is usually held on the main street of a neighborhood.
The principal component of street fairs are booths used to sell goods (particularly food) or convey information; sometimes they have carnival rides and parades, as well. Many have live music and dance demonstrations.[1]
They are usually no more than a few blocks long, although some fairs, such as the 9th Avenue International Food Festival in New York City and the Solano Stroll in Northern California extend more than a mile. A fair only one block long is commonly called a block party.
A street fair in the historically seafaring neighborhood of Ballard, Seattle, Washington
Street fairs vary greatly in character, even within one city. Annual street fairs in Seattle, for example, include the University District Street Fair, featuring the work of numerous craftspeople, and requiring that the person who actually made the goods that are for sale must be present in their own booth; the Fremont Fair features crafts from around the world, as well as the Summer Solstice Parade and Pageant, famed for its painted naked cyclists. In the same city the Capitol Hill Block Party fences off several blocks, charges admission, and features many of the city's best known rock bands while the Chinatown-International District Summer Fair has a distinctly Asian-American and Pacific Islander flavor, with taiko drummers, martial arts demonstrations, and Hawaiian dance.
In Belgium, street fairs are known as braderies, which translates to roasting; a reference to the frequent roasting of meat at these events.

A recent piece from historian Erik Linstrum over on Aeon may be of interest to AHP readers. In "The Empire Dreamt Back" Linstrum explores the role of psychoanalysis in British colonial rule. The piece begins:
Every state needs to know about the people it rules. Censuses, property surveys and tax records are familiar and tangible expressions of the state's need to maintain power by accumulating knowledge. This is not just a matter of tedious bureaucratic record-keeping: especially when confronted with unfamiliar problems, states often turn to cutting-edge technologies and forms of expertise to make sense of the populations under their authority. In the early 20th-century Age of Empire, when European colonies stretched across the world, psychoanalysis was the novel technique of the moment. In an attempt to better understand their colonial subjects in those years, officials in the British empire undertook a curious and little-known research project: to collect dreams from the people of South Asia, Africa and the Pacific. The results were not what they expected.

Liquid Nitrogen Is Beautiful When It's Dancing Across Gasoline
Instead of mixing, it just spins a beautiful trail of gas.
Amber, Visual arts, Painting, Art paint,
Pouring liquid nitrogen on another liquid won't result in an instant block of ice, nor even a slushie. Ultimately, it'll have very little effect on the liquid below but, as YouTuber carsandwater illustrates, it will look very cool while it is busy having no effect.
In this random but mesmerizing video, you'll see a few spoonfuls of liquid nitrogen dance around on the surface of gasoline, rubbing alcohol, and water.
Because the liquid nitrogen is less dense than the water, it just floats on top instead of mixing in. And while it does, it sometimes forms a tiny bit of ice beneath it, which acts as an insulator and keeps the warm liquid somewhat separate from the cold nitrogen. In the meantime, the liquid nitrogen just floats around, spinning and emitting some really cool vapor shapes as it evaporates.
It's not quite as flashy as using liquid nitrogen to fight against a flamethrower, but it's probably a little safer.

How to use robots for mass customized production?
This project subsists on the translational discrepancies that arise during interplay between an excessively controlled but exceedingly irresolute digital environment and its materialization into the reality of physical space. sPhysical seeks the epitome of synthesizing digital tools with physical expression by re-conceptualizing material design processes and applications in the field of architecture. The problem of materialization exists as the limitation of digital control and resolution. Matter and form are subjugated through a logic of rigging, a concept derived from and informed by robotic motion-control, and embedded with a certain propensity and agency. A design methodology, one that realizes the potential of designed properties, will be achieved through the conceptualization of rigging matter and form.

That's why scabies treatment includes thoroughly laundering linens and clothing in hot water, plus vacuuming rugs and furniture.


Tree Guide
Planting trees correctly can be difficult. Most people don't notice one thing - the size of the tree. If you understand this, it makes it much easier. For example, if you plant one tree, then another one right next to it, one of them WILL NOT grow. Here's a guide to make your tree planting experience much better:
[edit] Fruit Tree
[edit] Get a Fruit
First off, you need a fruit. These all come from trees that are already planted. Your local fruits are the ones that started off in your town, and foreign fruits are ones that did not(these can be retrieved by various means, such as mailing request letters out to other villagers or simply borrowing some to plant from a friends linked Town). You can plant either type, but to being planting, I usually work with a foreign fruit, as you can get more Bells out of it. The only foreign fruit that is never seen in a town to start is the Coconut.
[edit] Get a Shovel
Such a tool is also necessary for this productive task. You can buy one at Tom Nook's Store for 500 Bells if you don't already have one, they can be found in stock usually every day(especially if you've upgraded to Nookington's. You could also get a Silver Shovel from Resetti in the city. Any version of this tool will do, so long as one is in your posession.
[edit] Dig a Hole and place the Fruit
Digging a hole is as simple as it comes. Just have the shovel equipped and press A on any game. Now, to throw the fruit in, you go to the menu, click on the fruit, and select the "Bury" option. Your character will automatically throw the fruit in and stamp dirt on top of it.
E = Empty spot
T = Tree
B = Building
R = River
C = Cliff
Below is the way to grow a tree.
These example tree locations will not grow.
Cliff blocking tree growth:
Building blocking tree growth:
Another tree located too close:
Located too close to the river:
[edit] Do you want another tree? (OPTIONAL)
If so, here's what you have to do: After planting the tree you just planted, dig a hole right next to it. If you want your town to be organized, dig two holes (going right or left). These are used as spaceholders in order to prevent lacking patterns. Now, dig a hole at the end of the one/two holes. This is the one you will use for the fruit. Throw the fruit in, and that tree will also sprout.
[edit] What do I do with the tree?
Nothing. Just let it grow, simple as that. If it doesn't grow, this could be because of one important factor: location. Some trees don't grow if you place them too close to something. For example, a tree right next to a building or posted sign probably won't sprout, because they both are up in the sky and both take up room. Remember these tips and you'll be fine.
[edit] Money Trees
[edit] Get some Bells
First things first: You need at least 1,000 Bells or this won't work at all. A popular theory is that the amount of bells buried effect the chance of the money tree sprouting. For example, 1000 bells would only give it a 1% chance of sprouting, where as 89,000 Bells would give you an 89% chance of the money tree sprouting. However the most important thing to remember, is that a money tree still grows like any other tree. If its position is bad, it won't grow just like any other.
[edit] Animal Crossing GC
In Animal Crossing on the Gamecube, in order to grow a money tree, you first need to find the glowing patch of soil within your town. Buried there will be 1000 bells. To grow a money tree, you must bury the amount of bells you wish to grow. 30,000 bells is the maximum you can plant, if the tree grows successfully, it will bare 3 x 30,000 bags of bells, equalling 90,000 bells.
Note: You don't need a golden shovel for this. Although whether using one increases the chance of the money tree growing is unknown. You can only grow the money tree by planting it in the glowing patch, meaning only one per day can be planted, and the glowing patch may not be in a position enabling it to grow, so choose your patches carefully in order to not waste your bells!
[edit] Animal Crossing Wild World
There are no glowing patches in Animal Crossing Wild World, but using a Golden Shovel allows you to plant money trees where ever you like. Please note, buring money with a regular shovel will not work, it must be golden in order for the tree to sprout. You can obtain a golden shovel by burying a regular Shovel for 24 Hours. After you dig it up, you will have a Golden Shovel.
[edit] Plant the Bells
If you remember how to plant the Fruit, this is basically the same thing, but with a few changes. First off, you have to get a bag of bells by clicking on your amount of Bells in the menu and getting the Bells into a bag. Now, click on that bag and bury it in the hole.
[edit] Tips
Remember to plant your money tree in a good place so it has the best chance of sprouting. Although the theory of "more bells better growth" is popular, its not certain, so think carefully before buring ALL your bells.

I know regular PCA does not follow probabilistic model for observed data. So what is the basic difference between PCA and PPCA? In PPCA latent variable model contains for example observed variables $y$, latent (unobserved variables $x$) and a matrix $W$ that does not has to be orthonormal as in regular PCA. One more difference that I can think of regular PCA only provide principal components, where PPCA provides the probabilistic distribution of the data.
Could someone please through more light on the differences between PCA and PPCA?

Seen a Dolphin in the Thames? Story behind the lamps on the Thames Embankment
Many capital cities around the world have a river running through them. However, when it comes to the Thames, one thing that makes it so recognisable is the striking Victorian lamps lining the Embankment. The street lighting in question are called the 'Dolphin lamps', but actually appear to be sturgeon fish.
Prior to Victorian times, the Thames was a lot wider in the centre of town, but was slimmed down by the building of the Victoria Embankment on the north side in the late 19th century. Sir Joseph Bazelgette came up with a scheme to reclaim some 22 acres of marshland and built a new road and sewage system for the rapidly expanding capital. While this transformed the city, it also meant many riverside buildings were demolished, such as York House. Building of the Victoria and Chelsea Embankment meant Londoners had somewhere new to stroll beside the river so of course, some attractive new street lighting would be required.
Step forward George John Vulliamy, the Superintending Architect of the Metropolitan Board of Works, who created the unique riverside lamps built into the retaining river wall in 1870. Many different designs were submitted, including one by Bazelgette, however Vulliamy's designs were chosen for the centre of town. The cast-iron lamps featured two sturgeons with their bodies wrapped around the lamp column. Facing the Embankment, the face of Neptune peered out with the year 1870 inscribed underneath him. Vulliamy was said to have been inspired by the dolphin sculptures on the Fontana del Nettuno in Rome's Piazza del Popolo during his extensive travels around Europe. As well as the lamps, Vulliamy also designed the pedestals and sphinxes for Cleopatra's Needle – the ancient Egyptian obelisk gifted to London by Egypt in 1819.
For decades, these lamps only stood on the Victoria Embankment. However, in 1977, city authorities decided to create replicas on the opposite Albert Embankment on the Southbank to commemorate the Queen's Silver Jubilee. Instead of the year underneath Neptune on the Victoria Embankment, 'EIIR' was inscribed to mark Queen Elizabeth II.

Scholars of U.S. Culture and History Sharon Holland, Thomas Foster, Francesca Royster and John Shanahan explore the unexpected fluidity of interpersonal relationships across race and class in colonial America.
Toni Morrison's novel A Mercy represents a wide range of alliances between white indentured servants and free blacks, between enslaved and free blacks, between Native Americans and blacks, between mistresses and servants, and between hetero and non-heteronormative men. How do these relationships challenge our assumptions about traditional categories of identity and difference? What are the points of shared stakes and tension between groups?

How to tune a car sound system: adding a 4-channel amp
Buck Pomerantz
More from Buck Pomerantz
Rockford Fosgate Power T400X4ad
Rockford Fosgate Power T400X4ad 4-channel amplifier
Adding a 4-channel amp to your car stereo system — two channels to run the front speakers and two channels to run the rear speakers — not only raises the sound level, but also greatly increases the sound quality of your music. This is how I'd tune it up:
 1. Before turning on your system, make sure your amplifier's gains are set to their minimums, their highand low-pass filters are off (set to "all pass" or flat), and that any bass and treble boosts are also off.
 2. Turn on all the units of your system. Set your receiver's tone or EQ controls, its balance, and its fade to their middle, off, or flat positions. Note where the settings were as you might want to restore them later. If you have a subwoofer in your system, turn its amp gain all the way down.
 3. Play your test music. That's a recording you are very familiar with and know what it's supposed to sound like. It has plenty of sonic variety: lots of very high notes like flutes, brass, and cymbals, lots of mid-range content like piano, guitar, and vocals, and lots of very low notes like bass and drums. And you will listen to it over and over again. (For steps 4 through 10, while you're setting the amplifier's gains, it is best to play the loudest passages of your song selection.)
 4. Set the receiver's fade control all the way to the front speakers.
 5. With your amplifier's gain controls still all the way down, turn the receiver's volume up to ¾ full, or until the music sounds distorted. (If you don't hear any music at all, try turning the amp's front gain control up slightly until you do.) If you hear distortion, turn down the receiver's volume until the distortion goes away and the music sounds clean.
 6. Now turn up the front gain control of your amp until the music distorts, then turn it down so it plays clean again.
 7. Turn the receiver volume down.
 8. Set the receiver's fade control all the way to the rear speakers.
 9. Again, turn the receiver's volume up to ¾ full and turn up the rear gain control of your amp until the music distorts, then turn it down so it plays clean again.
 10. Turn the receiver volume down.
 11. If you have no subwoofer in your system, restore your receiver's original tone, balance, and fade settings now. Or, you can refer to "How to Tune a Car Sound System: Part 1" for help in tuning your stereo to sound its best. Another tip is to engage the high-pass filter on the front channels of your 4-channel amp, and tune it to eliminate some of the low notes coming from the front speakers in order to bring extra clarity to your soundstage. (That's the ability of your stereo to sound like a band is playing in front of you, live in your car.)
 12. If you do have a subwoofer in your system, adjust the receiver's fade control to the front speakers only and turn up the volume until the music is loud, but not uncomfortable. Engage the high-pass filter of the amplifier's front channels and adjust it so the bass notes disappear. Fade the receiver to the rear speakers only and engage and adjust the rear channels' high-pass filter until the bass disappears there too. Return your receiver's fade control to its original position.
 13. Slowly turn up the gain of your subwoofer amplifier until the bass notes sound balanced and smoothly blended with the rest of the music. Your sub amp's low-pass filter should already be tuned to reproduce only the low notes. You can refer to Tuning Your Subs, for help in fine-tuning your subwoofer system.
 14. If your highs and lows seem balanced but the bass sounds like it's coming from the rear, adjust the sub amp's low-pass filter lower to "de-localize" it. Pay close attention to the "crossover area", the parts of the music played by both the full-range speakers and your subwoofer. Smooth any roughness by fine-tuning the filters. For instance, if the vocals sound tinny, you can adjust the high-pass filters on your 4-channel amp to include more low notes. If the vocals sound boomy, tune the high-pass filters higher.
Take your time and tune it all for your own ears and you will never go wrong.

There have been many reports of people being investigated and busted for marijuana cultivation because their homes were monitored with an Infrared Heat Sensing Device.
It works like this; If the authorities suspect someone is cultivating marijuana, they set up surveillance of the home or building and use an infrared camera to measure the amount of heat radiating off the structure. They then compare the targeted structure to surrounding buildings or homes to gauge what they think should be the normal amount of heat emitted from a particular structure.
In some parts of Europe, the authorities don't even wait for a lead from an informant to give them the heads up, on possible marijuana grow operations. They simply take to the air and use their high-tech surveillance cameras and scan the roofs and walls of homes in residential areas and buildings. If a home is identified as possible marijuana grow operation because of the heat radiating off the structure, that home or building becomes the target of further investigation and possibly a raid.
Using an HID lamp will emit too much heat that could be inspected by infrared camera. Now, LED grow light could deal with very well because it is a cool light source which makes authorities can not find what you do inside. So more and more growers are replacing their HID lamp by LED grow light.

Brown fat is a special kind of fat, with small vacuoles in the cells rather than a single large oil drop.
Brown fat is also rich in mitochondria.
Mitochondria are brown. Can you figure out why? Remember all the cytochromes which they contain. Then think of all these colored substances mixed together, like your tempra paints when you were in grammar school. They make brown.
The abundance of mitochondria accounts for the color of liver, kidney, myocardium (mixed with myoglobin for a red-brown), and brown fat.
This is brown fat. You'll have no trouble finding the capillaires; brown fat is generously supplied.

Open colormap editor
colormapeditor displays the current figure's colormap as a strip of rectangular cells in the colormap editor. Node pointers are colored cells below the colormap strip that indicate points in the colormap where the rate of the variation of R, G, and B values changes. You can also work in the HSV colorspace by setting the Interpolating Colorspace selector to HSV.
You can also start the colormap editor by selecting Colormap from the Edit menu.
Node Pointer Operations
You can select and move node pointers to change a range of colors in the colormap. The color of a node pointer remains constant as you move it, but the colormap changes by linearly interpolating the RGB values between nodes.
Change the color at a node by double-clicking the node pointer. A color picker box appears, from which you can select a new color. After you select a new color at a node, the colors between nodes are reinterpolated.
You can select a different color map using the Standard Colormaps submenu of the GUI Tools menu. The Plotting Tools Property Editor has a dropdown menu that also lets you select from standard colormaps, but does not help you to modify a colormap.
How to Perform
Select a built-in colormap
Tools > Standard Colormaps
Add a node
Click below the corresponding cell in the colormap strip.
Select a node
Left-click the node.
Select multiple nodes
Adjacent: left-click first node, Shift+click the last node.
Nonadjacent: left-click first node, Ctrl+click subsequent nodes.
Move a node
Select and drag with the mouse or select and use the left and right arrow keys.
Move multiple nodes
Select multiple nodes and use the left and right arrow keys to move nodes as a group. Movement stops when one of the selected nodes hits an unselected node or an end node.
Delete a node
Select the node and then press the Delete key, or select Delete from the Edit menu, or type Ctrl+x.
Delete multiple nodes
Select the nodes and then press the Delete key, or select Delete from the Edit menu, or type Ctrl+x.
Display color picker for a node
Double-click the node pointer.
Current Color Info
When you put the mouse over a color cell or node pointer, the colormap editor displays the following information about that colormap element:
 - The element's index in the colormap
 - The value from the graphics object color data that is mapped to the node's color (i.e., data from the CData property of any image, patch, or surface objects in the figure)
 - The color's RGB and HSV color value
Interpolating Colorspace
The colorspace determines what values are used to calculate the colors of cells between nodes. For example, in the RGB colorspace, internode colors are calculated by linearly interpolating the red, green, and blue intensity values from one node to the next. Switching to the HSV colorspace causes the colormap editor to recalculate the colors between nodes using the hue, saturation, and value components of the color definition.
Note that when you switch from one colorspace to another, the color editor preserves the number, color, and location of the node pointers, which can cause the colormap to change.
Interpolating in HSV. Since hue is conceptually mapped about a color circle, the interpolation between hue values can be ambiguous. To minimize this ambiguity, the interpolation uses the shortest distance around the circle. For example, interpolating between two nodes, one with hue of 2 (slightly orange red) and another with a hue of 356 (slightly magenta red), does not result in hues 3,4,5...353,354,355 (orange/red-yellow-green-cyan-blue-magenta/red). Taking the shortest distance around the circle gives 357,358,1,2 (orange/red-red-magenta/red).
Color Data Min and Max
The Color Data Min and Color Data Max text fields enable you to specify values for the axes CLim property. These values change the mapping of object color data (the CData property of images, patches, and surfaces) to the colormap.
This example modifies a default MATLAB® colormap so that ranges of data values are displayed in specific ranges of color. The graph is a slice plane illustrating a cross section of fluid flow through a jet nozzle. See the slice reference page for more information on this type of graph.
Enhance Colormap
This example modifies a default MATLAB colormap so that ranges of data values are displayed more prominently.
Create a slice plane for the flow dataset:
[x,y,z,v] = flow;
hz = slice(x,y,z,v,[],[],0);
hz.EdgeColor = 'none';
hz.FaceColor = 'interp';
Start the colormap editor:
To reveal more information about the flow data, create more color variation in the region of interest. Add the color red for the largest color data value and blend it with the yellow and orange colors:
The new colormap reveals more of the flow data variation in the higher data values:
Saving the Modified Colormap
You can save the modified colormap using the colormap function or the figure Colormap property.
After you have applied your changes, save the current figure colormap in a variable:
mycmap = get(fig,'Colormap');
To use this colormap in another figure, set that figure's Colormap property:
To save your modified colormap in a MAT-file, use the save command to save the mycmap workspace variable:
To use your saved colormap in another MATLAB session, load the variable into the workspace and assign the colormap to the figure:

The Quality Enhancement Plan (QEP) is the component of the reaffirmation process that reflects and affirms the commitment of SACS to enhance the quality of higher education and focus on student learning. The QEP describes a carefully designed course of action that addresses a well-defined and focused topic or issue related to enhancing student learning. The QEP will be embedded within JMU's ongoing integrated institution-wide planning and evaluation processes. The topic may evolve from the existing process or from others related to the university's internal reaffirmation report and review.
Developing a QEP as part of the reaffirmation process is an opportunity for us to enhance overall institutional quality and effectiveness by focusing on an issue the institution considers a way of improving student learning. The evaluators expect the QEP to present a clear and comprehensive analysis of the selected topic and show its crucial importance to the institution. The QEP is expected to include:
- A university-wide process for identifying key issues
- Broad-based involvement of institutional constituents in the development and implementation
While the Compliance Certification focuses on the present, the QEP looks to the future. Topic selection will begin soon. If you have an idea for how JMU can enhance its student learning, you could be part of the QEP! Go to _URL_ for more information and to submit your proposal.

Objectives: Motor vehicle-pedestrian crash is a significant public health concern. The urban campus of Georgia State University poses unique challenges due to a large number of students and university employees. The objectives of this study are twofold: (1) to examine the correlation between specific features of the built environment on and around the University campus and pedestrian crashes; and (2) to identify crash clusters in the study area using network-based geospatial techniques.
Methods: We obtained pedestrian crash data (n=119) from 2003 to 2007 from Georgia Department of Transportation and evaluated environmental features pertaining to the road infrastructure, pedestrian infrastructure and streetscape for each road segment and intersection. Prevalence rate of each feature with pedestrian crashes present was calculated. We used network-based Kernel Density Estimation to identify the high density road segments and intersections, then used network-based K-function to examine the clustering of pedestrian crashes.
Results: Over 50% of the crosswalk signs, pedestrian signals, public transit, and location branding signs (more than three) at intersections involved pedestrian crashes. More than half of wider streets (greater than 29 feet), two-way streets, and streets in good condition had pedestrian crashes present. Crashes occurred more frequently in road segments with strong street compactness and mixed land use present and were significantly (p<0.05) clustered in these high-density zones.
Conclusions: Findings can be used to understand the correlation between built environment and pedestrian safety, to prioritize the high-density zones for intervention efforts, and to formulate research hypotheses for investigating pedestrian crashes. [West J Emerg Med. 2010; 11(3): 295-302.]

By using you can cycle through the three definitions (I decided to use files instead of functions, as functions use up memory in every copy of vim that you start, while files that are never "sourced" don't).
To use those files store them in some directory (and make sure to change the last line in each to point to the correct directory):

An special technique, developed by Ajax Equipment, uses a multiple stage insert system to overcome bunker flow problems, creating a more favourable approach to existing outlets and spreading the flow to previously "dead" storage areas of the bunker. The insert system has been used at Tata Steel Europe at its plant in Scunthorpe, UK, to overcome coal bunker flow problems.
Many power generation and industrial processes rely on storing coal in large bunkers. Over time changes in the type and quality of coal can lead to poor flow during discharge, causing processing delays and significantly reducing the bunker's storage capacity. Manual intervention is frequently used to promote flow; however, this is a hazardous process for operators, and fails to provide a long-term solution to the problem.
An innovative technique developed by solids handling equipment specialist, Ajax Equipment, uses a multiple stage insert system to overcome bunker flow problems, creating a more favourable approach to existing outlets and spreading the flow to previously 'dead' storage areas of the bunker. The insert system has been used at Tata Steel Europe (formerly Corus Long Products) – a manufacturer of steel products at its plant in Scunthorpe, UK, to overcome coal bunker flow problems.
In the ironmaking process, molten iron is produced in a blast furnace using agglomerated iron ore, limestone and coke. The coke is produced in large coke ovens from coal with special properties. Coal is crushed and blended on the Scunthorpe site and transported to Appleby Coke Ovens via a series of belt conveyors. It is then is stored in a large concrete service bunker which is sited above, and in the centre of, the oven batteries.
The concrete service bunker (Fig. 1) was built in 1937 and is divided into two rectangular sections, one section holding 3000 tonnes of coal and the other holding 1000 tonnes of coal. It is about 17.5 metres tall and the 1000 tonnes section is 8 metres × 13 metres, whilst the 3000-tonne section is 20 metres × 13 metres. Coal is fed into the top of the bunker where it is distributed to one of the two sections and stored ready for discharge under gravity. Coal is discharged via a number of rows of outlets at the base of the bunkers into the charge cars.
In 1968 half of the outlets were blanked off and lightweight concrete was used to build up a steeper approach to the remaining outlets with smooth glass tiles laid on top to encourage flow. The outlets are arranged in five rows of four outlets on the 3000-tonne side and two rows of four outlets on the 1000-tonne section. Each row of four outlets operates together to fill a charge car which feeds the oven. Each outlet has a 640-millimetre diameter steel throat cast into the concrete. Slide gates are fitted to each outlet and the charge cars are filled with 17.5 tonnes of coal in, hopefully, one minute.
The bunker was originally designed to store local Lincolnshire and Yorkshire coal, but today it holds blended imported coal from around the world. A typical blend may consist of 60 percent Australian Coal and 40 percent North American. It is the particularly cohesive properties of the imported coal that has exacerbated the bunker's flow problems, making the material more difficult to handle.

New Zealand's capital city lies within the earthquake-generating collision zone between two of the Earth's great tectonic plates, and sits on top of one of the zone's most active geological faults - the Wellington Fault.
The Wellington Fault forms distinctive landscape features running right through the central city. Intensive research has been done to understand the nature of the fault and the best ways to reduce possible earthquake damage and loss.
- Wellington's Shaky Foundations
- How often do earthquakes occur along the fault?
- How much do the Wellington fault lines move?
- What would a major Wellington earthquake be like?

temperatures and produces more heat. That's why you feel so comfortably warm when you enter your home again!
Even if going outdoors when you feel cold seems counterintuitive, it's not! It increases your bodies' resistance to the cold and helps you stay warm without using the heater.
On top of that, a walk is healthy and relaxing. You should be doing it more anyways (me too)!
21. Use a hot water bottle
Finally, here's another useful and effective way to cheaply heat in a room!
Running a kettle to boil your water costs next to nothing. It costs only 1 or 2 cents to heat the water to fill a hot water bottle that can keep you warm for 30 minutes to 2 hours (source).
In big rooms, a water bottle will stay hot for 30 minutes, wheres in your bed it will provide you with heat for up to 2 hours.
How water bottles are an incredibly cheap way to heat your room. You focus the heat just on yourself (similar to electric blankets). Absolutely no energy is wasted to heat the air in the room you are in.
Even if you boil 10 hot water bottles to stay warm throughout the evening (5 hours), that's only 20 cents of heating costs.
In contrast, a regular heater would cost about $0.40 to $1.50 to heat for the same time.
Also, hot water bottles are cheap (compared to a wood stove or solar panels)! It costs around $10 to become a proud hot water bottle-owner. That's a very small amount for so much value!

Conclusion – The 21 Cheapest Ways to Heat a Room
Most of the cheapest ways to heat a room I gave you in this article involve heating just what's necessary. Heat only the room you're in. Be as efficient as possible.
This way you can save hundreds of dollars each year. That's money you can freely spend elsewhere.
Also, you can reduce the need for heat by staying active: Jumping jacks or having a walk outdoors will increase your body temperature. If you do these things you stop freezing and you don't need to turn up the thermostat.
Even if you pick only 1 or 2 of these tips, you will make a significant impact on your heating bill! So, chose one of these cheapest ways that you like to implement to heat your room and start saving money!
My personal favorite cheapest way to heat a room is by using a space heater.

I don't believe that having similar solid angles is sufficient to determine the equal probabilities of the die landing on faces with similar solid angles.
Here is a construction for 2-d die (which can easily be converted into prismatic die, disregard if the die lands on "top" or "bottom" face, and look at the relative probabilities of landing on the prismatic faces)
Using polar coordinates $(r,\theta)$, let's define a fair hexagonal die's profile as the closed path determined by the six vertices at
$(1,\frac{\pi}{3}), (1,\frac{2\pi}{3}), (1,\pi), (1,\frac{4\pi}{3}), (1,\frac{5\pi}{3}), (1,{2\pi})$
Now let us define an unfair hexagonal die's profile as the path defined by the polar coordinates
$(1,\frac{\pi}{3}), (1,\frac{2\pi}{3}), (100,\pi), (1,\frac{4\pi}{3}), (1,\frac{5\pi}{3}), (100,{2\pi})$
Now this die's center of mass (center of gravity) remains at $(0,0)$ since the material the die is composed of has uniformly homogeneous density. This unfair die also has each prismatic face subtending equal solid angles (and equal angles of $\pi/3$ for each edge in the $2$-dimensional case), however the this unfair die is highly biased towards landing on two faces to the detriment of the other four faces probabilities.
Thus Benoît Kloeckner's conjecture that
is incorrect.
In fact, using this polar coordinate approach, it can be seen that using any three radii greater than $0$ in length yields a rotationally symmetric die profile with equiangular faces (edges which subtend equal angles in $2$-d, prismatic faces which subtend equal steradians of solid angle in $3$-d) and with center of mass still at $(0,0)$:
$(r_1,\pi/3), (r_2,2\pi/3), (r_3, \pi), (r_1,4\pi/3), (r_2,5\pi/3), (r_3,2\pi)$
but very few of these would be fair. Particularly the non-convex profiles, which also are equiangular, but make it possible to land on pairs of vertices/edges without landing on a specific face

There is a simpler example : take a parallelogram with two very long opposite edges. Then the two short edges are unstable, not matter how you throw your die you will not be able to make it land on a short edge, but the angle under which a short edge is seen is not zero. – Guillaume Brunerie Nov 20 '10 at 20:58
_USER_-Brunerie, your parallelogram construction does not provide for equiangular faces, whereas the construction above is proven to create equiangular edges in the 2-d case, and prismatic faces in the 3-d case which all subtend equal steradians of solid angle. – sleepless in beantown Nov 21 '10 at 1:25
This is a tentative to solve the questions that arose in Matt Fayer's answer and comments, regarding the impossibility of a fair experiment.
Appealing to Information Theory, it is established that randomness is equivalent to the lack of information. More formally, uniform measures are the one that maximize Shannon's entropy. Conversely, complete knowledge is equivalent to Dirac measures. From this point of view it is clear that a perfect machine, where perfect means indeed complete knowledge, can do whatever you want and, in particular, is able to land a die always on the same face (this is a Dirac measure!).
After these observations, it seems to me clear that a fair throwing can be simulated imposing the lack of knowledge: the person who throw the die must be blinfolded; (s)he has to throw the die uniformly (i.e., as already suggested, chosing the Haar measure on $SO(3)$) - this can be forced using heavy gloves, but also more naturally using die with a uniform structure (I will come back to this point in a moment). On the other hand, a person who bet on the die is not allowed to use any other tool but his own eyes, in the case of uniform structure (in case of heavy gloves, he's blinfolded either). In this case, the Nash equilibrium of the ideal game between the two players (who throws and who bets) is the uniform measure on the number of faces of the die; i.e. the experiment is fair.
A comment about uniform structures: this probably brings to classical interpretation more or less discussed in other answers: I am thinking of a cube; more specifically, keeping this analogy with the real-world, I am thinking to something with the following property: if you close your eyes and you are allowed only to touch the die, then you cannot distinguish two different faces and the edges are trascurable; i.e. since the set of human beings is finite, take $\epsilon$ small enough such that every imperfection of the die is smaller than $\epsilon$.
P.s. maybe I should write this somewhere, but an important observation to keep in mind is that fairness, randomness, knowledge and so on are subjective. Something can be really random iff it is perfectly isolated.

The Proper Way To Create A Sense Of Urgency For Higher Conversion Rates
Forbes Agency Council
Jason Hall specializes in creating brand awareness, traffic and lead generation, marketing funnels, social media campaigns and more.
"Buy now!" "Don't wait!" "Today is the last day of our extra-special bonus offer only available to you!"
Creating a sense of urgency is a useful marketing tool to drive sales, move stock or differentiate yourself from your competitors. Unfortunately, many businesses use it for only these short-term purposes. When they do, they miss out on ways to add value to their business that keeps customers coming back.
Defining A Sense Of Urgency
The term "sense of urgency" appears as vague business or marketing jargon and describes a feeling that is very real for customers. Marketers and writers use it as a tool to inspire customers to shift their mindset from "Let me bookmark that" to "Where can I buy this now?"
So, while vague, it's that vagueness that is helpful, because it allows you to adapt it to your unique sales funnel. It enables you to channel customers from the "later" column to the "now" column in however you can apply that to your business.
Psychology Is On Your Side
Encouraging customers to act now rather than later isn't only good for your bottom line. It also uses psychology to your benefit, as it taps into two essential social psychological principles: fear of missing out and scarcity.
Fear of missing out, or FOMO, refers to the fear of not being able to partake in a desirable opportunity. Scarcity in psychology is similar to a shortage in economics. Humans assign more value to objects that they have limited access to and less to objects that are easy to get. Scarcity implies limitations.
In other words, when it comes to urgency, people perceive scarcity and think they need to act now. However, while creating a sense of urgency brought us the idea of the "limited time only" offer or the "don't wait, this offer ends soon" proposition, an overtly manufactured sense of urgency probably won't grow your business.
The sense of urgency definition shouldn't be "I have to get it before it's gone!" Instead, make it more about "How did I ever live without this product?" Here are some ways to do that:
Build Trust
For scarcity to work in a way that's valuable to your business, buyers need to trust you first. Trust and credibility are vital in every business relationship. If those things aren't evident to new customers, then you'll be the one who misses out.
How do you build trust and credibility? By consistently positioning yourself as a resource your customers can count on. Those two aspects also need visibility to thrive, so make sure contacting you is easy. Display your phone number, customer contact email and address clearly on your site. Live-chat options can also make trust-building easier.
A strong guarantee also makes a world of difference. Customers want to know that they aren't left with a product they don't want because they fell for your sales tactics. Also, don't forget to encourage people to review your business on their own time. Websites like Yelp can be scary if you are getting negative reviews but can also set you apart from your competition.
Make Your Offer Relevant
Companies choose from one of two ways to improve their relevancy. They either:
 Improve their product relevancy to their audience, or
 Improve their audience relevancy to their product
Either option works, but if you already offer an established product that customers rely on, you'll find that the latter is the better -- and less expensive -- option.
If your company is already relevant but you need to change your traffic, use your CRM data to identify what traffic sources already work for you and what sources might someday work for you. Use Google Analytics to see what sources of traffic deliver. Then, use the data to hone your strategy before launch. Not only will you learn more about where your visitors come from, but you'll get insights into those customers.
Improve The Value
Improving value doesn't necessarily mean adding more value. As it turns out, you might need to take away some of the product's value to improve it. If that sounds like a paradox, then you're right. Welcome to the weird world of A/B testing.
Taking your product value to the ceiling might look like the deal of a lifetime on the surface, but some customer groups might see extreme value as far more work. For example, a $2,500 software bundle sold for $100 might be a steal. At the same time, it can overwhelm customers with choices and options. It's a tremendous amount of software for a group that may only want one or two pieces of it.
Ask yourself whether your value is too much or whether less is more. Then, go out and A/B test it.
Use The Six Nudges To Jumpstart Conversions
Nudging is a simple tool to encourage customers to make a decision quicker but in a gentle way. It doesn't scream "buy now." It says, "better today than tomorrow."
Digital marketing expert Avinash Kaushik curated a list on six ways to gently nudge customers:
 Stock status (showing how much product is available)
 Current price shelf-life (getting consumers to take advantage of the best deal)
 Delivery times (giving them a time they will actually have your product)
 Social uses (illustrating demand through social media)
 Competitor comparisons (set yourself apart from the competition)
 Personalization (show you connect with your customers)
These techniques all create urgency and anticipation for your customer base, making them think they need your product immediately.
Build Urgency Right Now
By now, you can see that urgency isn't just a sales and marketing tactic. It strikes at the heart of your business and customer acquisition funnel. Urgency makes a clear, relevant promise to customers and removes the barriers to purchase for increased sales and increasingly loyal customers.
By creating a sense of urgency in the right way with your customer base, you will have them buying your products and, more importantly, coming back for more.

When programming Clojure, sometimes you need the equivalent of Common Lisp's
prog1 macro. It's like Clojure's
do except that it returns the value of the
first form, not the last one.
You could depend on useful, which calls it
(defmacro returning "Compute a return value, then execute other forms for side effects. Like prog1 in common lisp, or a (do) that returns the first form." [value & forms] '(let [value# ~value] ~_USER_ value#))
Of course, when you're in a hurry, there's no time for adding new dependencies.
There's not even time to write your own inline version of the macro. Besides,
they say that you shouldn't ever write your own macros. So what do you do? You
(doto x (do (y) (z))) ;; returns x
But maybe instead of
x you have
(a complicated form) and you want to give
its result a name. Luckily there's
(doto (a complicated form) (as-> x (do (y x) (z x))))
When you're debugging a long
-> thread, a print function that returns the
printed value would be handy so you could insert it in the middle of the chain.
This is of course exactly what tools.trace is for. But again, who has
time for adding dependencies? Just use
(-> thing do-something-1 do-something-2 (doto prn) do-something-3)
By the way, the other day I wrote this macro that resembles
(defmacro if-> [expr cond then else] '(let [e# ~expr] (if ~cond (-> e# ~then) (-> e# ~else))))
I used it with a builder object. The code looked something like this:
(-> (Builder.) (.withSetting "password" "kissa2") (if-> production-mode? (.useProductionMode) (.useTestingMode)) (.build))
Can somebody figure out how to do that nicely without writing a macro?

Filling Seams and Sanding the Aircraft Model
Removing the seams and joint lines is necessary when building model airplanes. Many assemblies often result in unnatural gaps or cracks in the fitting. Among the most common problem areas are the wing roots and the mating lines between both sides of the fuselage. To produce an authentic looking aircraft model, I recommend the following technique.
To begin, you will need various grades of sandpaper, including 600ALO, 400ALO, 320SIL and 150SIL. Other necessary tools include; a sharp hobby knife, a paintbrush and a container with a small amount of water. We will also cover the use of model putty and Tenax-7R, a fast-dry formula used for welding plastic scale model parts.
I should remind the reader that when building model airplanes using hazardous materials, it is very important to have plenty of ventilation around the working space. You should also pay close attention to all the warnings that come with each chemical, usually found on the product container.
This technique will be illustrated using the fuselage parts of the aircraft model. You can begin by welding the left and right sides using Tenax-7R. With medium pressure, hold both sides of the fuselage together and simply touch the entire seam using a paintbrush. Once you have completed the application, gradually increase your hold pressure over the next 10 seconds until you have a firm bond. Tenax-7R will actually fuse the plastic scale model by slightly melting the parts together. Allow about 5 minutes for the weld to dry and lightly scrape off any excess chemical using a hobby knife.
Should there be any imperfections on the aircraft model, such as gaps, pits or scratches, you can apply model putty (filling material) using a toothpick. Be very careful not to smudge or place it on areas where it is not necessary as excess putty will go a long way in hiding surface details such as rivets and panel lines. If possible, mask off the crack or opening to be filled using tape. Then, apply a thin coat of putty and allow about 30 minutes for drying time. Once the putty has dried completely, sand the area down to the level of the tape using 600 ALO sanding paper. If the gap has not filled, or if the putty has dried and contracted to a groove between the parts, re-apply more putty and repeat the dry time and sanding process. Once you have a level surface, remove the tape and begin fine sanding your work.
As one of the most important steps in building model airplanes, the sanding process should be very meticulous. You can begin sanding the aircraft model using 600 ALO paper to go over all the areas where putty and Tenax-7R was used. Be extra cautious not to sand off too much, as you may end up losing some of the finer surface details. You can then dip a paintbrush in water, and moisten the entire sanded area. Once again, using 600 ALO paper, wet sand the area until it begins to look smooth. For an accurate sanding job, this process should always be done under a strong light so that rough areas can easily be spotted. Before moving forward, clean your aircraft model using water and dry it with a rag or paper towel.
Once the plastic scale model has dried completely, do a thorough check for rough patches and use 400 ALO or 320 SIL paper to repeat the process, sanding and wet sanding the working area. You can complete this technique using a fine 150 SIL sanding paper. This final sheet will leave your aircraft model looking smooth and natural, without any visible blemishes. This step does not require wet sanding. Simply run your 150 SIL paper over the entire sanded area. Once this is complete, your aircraft model is ready for painting.

Division of Fishes History
Ichthyology - The Early YearsThe Division of Fishes traces its origin back almost as far as The Field Museum itself. Ichthyology began under the leadership of assistant curator Oliver Perry Hay in 1894. Hay, while primarily interested in North American fossil vertebrates, started the fish collection. In 1897, Hay was replaced by Seth Eugene Meek. Meek began the Museum's long-term commitment to the collection of and research on Neotropical fishes. While Meek and his collaborators made extensive collections across Middle and northern South America, he is best known for his pioneering work on the freshwater fishes of Mexico and Panama (with Samuel F. Hildebrand). After the passing of Meek in 1914, a young Carl L. Hubbs was hired as an assistant curator in the Division of Ichthyology and Herpetology in 1917. During his brief career in Chicago (ending in 1920) and later at The University of Michigan and Scripps Institution of Oceanography, Carl Hubbs would go on to publish more than 700 scientific articles and be elected to the prestigious National Academy of Sciences.
Fishes - The Weed, Woods, and Grey Era
In 1921, the Division of Ichthyology and Herpetology, along with the other zoological divisions, anglicized its name to the Division of Fishes, Amphibians, and Reptiles and hired Alfred Cleveland Weed as its new assistant curator. Weed explored and published across the diversity of fishes, frequently publishing pamphlets and books aimed at educating the public about the biology of fishes. This focus on educating the public about fishes also manifested itself in his efforts to improve fish-related exhibits at the Museum. Other important endeavors included his participation in one of the early marine ichthyological explorations of Greenland in the late 1920s. Weed ended his career at The Field Museum as a full curator in the revamped Division of Fishes in 1942. Around the time of Weed's departure, Fishes expanded by promoting Loren P. Woods from previous staff positions in Education and Fishes to assistant curator in 1941 and making then volunteer, Marion Grey, an associate in 1943. Woods would be at the helm of Fishes for the next 37 years except for a four-year period (_PHONE_) when Marion Grey led the department while Woods served in the Navy during World War II. Grey would go on to publish 15 papers, principally on deep-water fishes, during her 22 years at The Field Museum. During this time, current curator emeritus, Robert F. Inger, spent a short time (_PHONE_) as an assistant curator of fishes before moving over permanently to Amphibians and Reptiles. After returning from the Navy, Woods participated in numerous marine collections to the Indian Ocean, western Atlantic, southeastern Pacific, Gulf of Mexico, and Caribbean. These extensive marine collections greatly expanded what had been a primarily freshwater collection. From these collections, Woods' scientific endeavors would lead him to publications on both freshwater and marine groups, but he is most remembered for his work on the damselfishes (Pomacentridae) and the squirrelfishes, alfonsinos, and nannygais (Berycoidei). Woods retired from the Field Museum after 40 years of service in 1978.
Fishes - The Johnson, Stewart, and Chernoff Era
Before Woods retired, Fishes hired Robert K. Johnson in 1972 to further research and collection efforts on marine fishes. While at the Museum, Johnson initially focused on the systematics of deep-sea fishes, primarily from the Aulopiformes (lizardfishes and allies) and Chiasmodontidae (swallowers). In 1975, Johnson traveled with several colleagues, primarily Dave Greenfield of Northern Illinois University (NIU), to the coast of Honduras. This trip began Johnson's long association with Greenfield that would lead to his adjunct appointment at NIU and numerous collection trips to Belize and Honduras that led to numerous papers on the ecology and systematics of reef fishes and tremendous collections. In addition to his appointment at NIU, Johnson had an adjunct appointment at the University of Chicago. It was this love of teaching that led Johnson to leave The Field Museum for a professorial position at the College of Charleston in 1986. Johnson always placed a large emphasis on service to his institution and his primary scientific society, the American Society of Ichthyologists and Herpetologists (ASIH). At The Field Museum, Johnson served as Chair of Zoology and played a major role in expeditions for members, including tours to the Gulf of California, Honduras, and Alaska. His tremendous service efforts were later recognized by the creation of the Robert K. Johnson Award for Exceptional Service after his untimely death in 2000. This ASIH award is given annually in his honor. Following Woods retirement, Donald J. Stewart was hired in 1979 to continue The Field Museum's excellence in Neotropical freshwater fishes. From 1978 to 1985, Stewart made extensive collections in South America, particularly expeditions to Ecuador, Peru, and Venezuela. Stewart is best known for his systematic work on armored catfishes (Loricarioidei) and the endangered Arapaima. His research interests remain in the ecology, conservation, and management of freshwater systems in South, Central, and North America in his current post as a professor of environmental and forest biology at the State University of New York's College of Environmental Science and Forestry in Syracuse.
Following the departure of Stewart and Johnson, Barry Chernoff was hired from the Academy of Natural Sciences in Philadelphia in 1987 to continue his work on Neotropical silversides (Atheriniformes) and tetras (Characiformes). In addition to substantive Neotropical fish collections (including several Aqua-RAPs with the Museum's ECCo: Environment, Culture, and Conservation program), Chernoff spearheaded efforts for the computerization of the Fishes collection. With support from the institution and the National Science Foundation (NSF BSR-_PHONE_, _PHONE_ and NSF DEB-_PHONE_, _PHONE_), Fishes was able to complete data capture and verification in a MUSE database. In addition to his efforts within Fishes, Chernoff also served as Chair of Zoology before his departure from the Museum in 2002 to take a faculty position in Biology at Wesleyan University in Middletown, Connecticut.
Fishes - The Modern Era
Since the early 1990s, The Division of Fishes has seen a number of changes to our collection management practices with the movement of specimen catalogs from pen and paper to electronic databases, the physical movement of the entire Fishes collection (now in the Collections Resource Center), and the ever increasing challenges associated with the loaning and shipping of specimens. The Fishes professional staff has guided the division through these advances as well as maintaining and caring for more than 1,700,000 specimens. Collection Manager Mary Anne Rogers (_PHONE_) oversaw the creation of the fish collection database, the migration of the entire database from MUSE to EMu, and the move of the entire collection to the Collection Resource Center. Rogers was instrumental in the creation of a diversity of Fishes procedures and polices relating to the care and handling of specimens and the shipment of loans according to IATA rules. Collections Assistant Kevin Swagel joined the museum in 1984 and eventually found a home in Fishes (1991-present). Swagel has now managed Fishes for more than 20 years. Swagel has been responsible for the day-to-day running of the division, including countless important duties ranging from the maintenance of the budget, to coordinating visitors, to ensuring the long-term stability of the Museum collections. As an all-around naturalist, Swagel combines his expertise with fishes with an intimate knowledge of birds and plants, often making collections across multiple zoological divisions and Museum departments. More recently, Swagel was part of the Fishes contingent that made deep-sea fish and invertebrate collection off of San Diego. Philip Willink (2002-2010) started at The Field Museum as a post-doctoral fellow working with Barry Chernoff on the Aquatic Rapid Assessment Program in South America, and he eventually transitioned into an Assistant Collection Manager position. During his time at the Museum, Willink continued our Neotropical collection and research efforts and really established a Chicago-based field program. Willink began studying Wolf Lake in southeast Chicago, and he was able to trace the species composition through time and human development. He also created ties to local researchers from the Department of Natural Resources and the Army Corps of Engineers. Through these efforts, he published a Fieldiana on the Fishes of Will County and is now working on the fishes of Chicago proper. As a collection manager, Willink's largest contributions were with the building of collections, identifying specimens in the backlog, spearheading efforts to process new collections, training students, volunteers, and staff in the identification of fishes, and the development of methods associated with digital photography and the Fishes image database.
In 2007, Chris Jones (2007-2011) and Susan Mochel transitioned from volunteers in Fishes to Collections Assistants. Together, they have worked on a number of projects, culminating in their project to photograph representatives of all of the nominal types included in the Fishes collections and their participation in the 2010 deep-sea fish expedition off of California. During his tenure, Jones has primarily focused on the identification of fishes in the division's backlog, identifying thousands of lots from localities ranging

June 25, 1998 PASCO, Wash., June 19 -- People who love kippers for breakfast, smoked salmon on their bagels, and caviar on their canapés, should welcome news of a new technique that could help to assure these delicacies contain precisely the right amount of salt. Researchers at Eastern Oregon University, La Grande, report that a new technique offers fish processors a safer and more economical way to assess how much salt they should use in the drying or smoking process. Salt content is not only crucial to the way fish tastes, but also is an important safety factor, since salt prevents the growth of bacteria in the roe and in the adult fish. Researcher Todd M. Rogers described the new method here today at the Northwest Regional Meeting of the American Chemical Society, the world's largest scientific society.
The researchers are using a machine--called a near infrared spectrophotometer--that analyzes the salt content of the fish to be processed while the fish are still alive. Traditionally, processors have had to kill the fish, grind up a portion of the meat or roe, and use a chemical method to measure salt content, thereby wasting part of the product. The spectrophotometer incorporates an optical-fiber probe that touches the scales of the living fish and records the volume of water and fat, which are known to be proportionate to salt content, in the meat or roe. Knowing the precise amount of salt already present in the fish, food processors can add the amount needed to meet safety standards and, at the same time, avoid sending overly salted products to the marketplace.
A nonprofit organization with a membership of more than 155,000 chemists and chemical engineers as its members, the American Chemical Society publishes scientific journals and databases, convenes major research conferences, and provides educational, science policy and career programs in chemistry. Its main offices are in Washington, D.C., and Columbus, Ohio.
