Development and validation of inexpensive, automated, dynamic flux chambers
Abstract. We developed and validated an automated, inexpensive, and continuous multiple-species gas-flux monitoring system that can provide data for a variety of relevant atmospheric pollutants, including O3, CO2, and NOx. Validation consisted of conducting concurrent gas-phase dry-deposition experiments, using both dynamic flux chambers and an eddy-covariance system, in a grassy clearing in the Duke Forest (Chapel Hill, NC). Experiments were carried out in June and September under a variety of meteorological conditions. Ozone-deposition measurements from the two methods matched very well (4–10% difference in mean flux rate) when the leaf-area index (LAI) inside the chambers was representative of the average LAI in the field. The dynamic flux chambers can be considered an accurate measurement system under these conditions.

The Tomb of Hafez or Hafezieh is referred to a cemetery complex basically erected in memory of Hafez Shirazi. The present buildings are designed by the French architect, André Godard, and built in 1935; but the primary structure was erected in 1452.
The Tomb of Hafez and its associated memorial hall, the Hāfezieh, are two memorial structures erected in the northern edge of Shiraz, Iran, in memory of the celebrated Persian poet Hafez. The open pavilion structures are situated in the Musalla Gardens on the north bank of a seasonal river and house the marble tomb of Hafez. The tomb, its gardens, and the surrounding memorials to other great figures are a focus of tourism in Shiraz.

George Washington
By Betty Kirkpatrick
Muckle is now best known to most people for its appearance in the old adage Mony a mickle maks a muckle. This is popularly thought to mean that a lot of small amounts of something will make a large amount of it. It is often used to try and encourage people to save little amounts of money in the hope, one day, that these will become a fortune.
The sentiment may be admirable, but the saying as it stands actually does not make much sense. Mickle and muckle, far from being opposites in meaning, actually mean the same thing. As nouns they both mean a large amount or a great deal of something. As adjectives they both mean large or great in size. Many Scots words have variations in spelling and muckle/mickle is an example. Meikle is another variation of the same word, as in the meikle stane (stone) mentioned in Tam o' Shanter:
And past the birks and meikle stane,
Where drunken Charlie brak's neck-bane:'
How the saying Mony a mickle maks a muckle came about is a bit of a mystery. The most likely explanation is that the phrase started out life as Mony a pickle maks a muckle. Pickle, unlike mickle, is opposite in meaning to muckle and means a small amount. This phrase, then, has the merit of making sense.
If that is the case, a most unlikely person appears to have been involved in the faulty rewording of the saying. That person is George Washington. In 1793 he referred in writing to a Scots saying: "many mickles make a muckle" adding "than which nothing in nature is more true". I doubt if he single-handedly caused the mickle problem, but he certainly added to it.
Mony a mickle maks a muckle might be linguistically inaccurate, but it has spread its wings further into England than most Scots words and phrases have done. To add to the confusion, a version of the saying has appeared in some English dialects as Many a little makes a mickle.
The word muckle is derived from Old English micel, meaning great or large, which is associated with Old Norse mikill of the same meaning. Muckle can be used as a noun, as in the saying under discussion, or as in They dinna think muckle o' him, used to emphasize a poor opinion of someone. However, muckle is often used as an adjective in a wide range of contexts, as in a muckle tree, a muckle hoose, a muckle difference, a muckle eejit (idiot) and so on.
Muckle feck refers to the larger or lion's share of something, muckle coat to a greatcoat and muckle chair to a particularly large armchair. The muckle tae is the big toe and the town of Langholm in Dumfriesshire is frequently known as the Muckle Toon.
Muckle is also found in compound adjectives such as muckle-moued, having an exceptionally large mouth. Muckle-backit means having a good strong back, always an asset, and muckle-boukit, in one of its senses, means having a large powerful physique. In its other sense it means pregnant, hardly a flattering description of a mother-to-be.
Muckle has extended its senses to mean adult or grown up. Thus an expression such as someone's muckle dochter can be ambiguous. She can either be a large (probably not a compliment) daughter or a grown-up daughter. Muckle can also mean high-ranking or important, as in the muckle fowk (people) of the toon.
Muckle fowk have often achieved their muckledom by being wealthy. This reminds me of another muckle saying: Moyen (influence) does muckle, but money does mair (more). True, very true. Our wealthy Westminster politicians are living proof of it.

 By coincidence I just came over the 'many a little makes a mickle' version, with a slightly different implication, in The House with the Green Shutters, p 115:
 [The average Scotsman] has expressed his love of festina lente in business in a score of proverbs – 'bit by bit's the better horse, though big-by-bi-g's the baulder'; 'ca' canny or ye'll cowp'; 'many a little makes a mickle'; and 'creep before ye gang'.

Well, assuming words are separated by spaces, to find lines with >= 5 words, do this:
$ grep -P '\w+\s+\w+\s+\w+\s+\w+\s+\w+'
Grep is not the best tool for the job though, try gawk:
$ gawk 'NF>4'
Gawk's NF variable holds the number of fields, by default fields are defined by spaces, so in a line of text each field is a word. The command above will print all lines containing more than 4 words.

But words can also be separated by comma. And at the end of the sentence there is dot. I try this: grep -E "(\w+[,.]+){25,}" and it seems to work allright. – quin61 Sep 5 '12 at 11:01
My gawk command counts fields _USER_, three spaces means four fields. The dot is irrelevant and, in normal text, there is a space after the comma. – terdon Sep 5 '12 at 13:32

Replace the number "3" if you want lines >= to a different value.
grep -E '^(\w+\b.){3}'

Spinning the Moon by Stephanie Dale - the 7th community play for Dorchester
Spinning the Moon is a compelling new community play based on documents provided by the DCPA Research Group.
Set in the early 16th century, the play, like Shakespeare's history plays, has taken a sense of what was happening in Dorset over a fifty-year period and has conflated those happenings to create a work of dramatic fiction.
Central to the action are the Trenchard family, who lived at Wolfeton House on the outskirts of Dorchester. The Trenchards are desperately trying to stop their home, and the people who work their land, from spinning towards economic collapse and ruining the lives of all who depend on the estate for their livelihoods. But the advice they take from a monk leaves their community fractured to the point of violent disintegration.
Characters in the play include: the Trenchard family, farmers, shepherds and their families, the Queen of Spain and her entourage and the cunning women who live in the hills.

Impact of oxygenated gasoline use on California light-duty vehicle emissions
Light-duty vehicle emissions were measured at the Caldecott Tunnel in August and October 1994. In the interval between these two periods, the average oxygen content of gasoline sold in the San Francisco Bay area increased from 0.3 to 2.0% by weight. Compared to the August (low-oxygenate) sampling period, measured pollutant emission rates during the October (high-oxygenate) sampling period for CO and VOC decreased by 21 ± 7 and 18 ± 10%, respectively, while NOx emissions showed no significant change. Formaldehyde emissions increased by 13 ± 6%, acetaldehyde emissions did not change significantly, and benzene emissions decreased by 25 ± 17%. Speciated VOC emission profiles show that the use of oxygenated gasoline resulted in higher MTBE and lower aromatic hydrocarbon emissions, higher isobutene, and lower aromatic aldehydes. The normalized reactivity of NMOG emissions did not change significantly between the low-oxygenate and high-oxygenate sampling periods. VOC exhaust speciation profiles for vehicles operating in the hot-stabilized mode at the Caldecott Tunnel match the speciation profile for cold-start emissions from new vehicles as measured in the Auto/Oil program. California's motor vehicle emission factor model, EMFAC7F, accurately predicts the VOC/NOx ratio measured at the Caldecott Tunnel in August, but underpredicts the observed CO/NOx ratio by a factor of 1.5−2.2 over the range of vehicle speeds observed at the tunnel.


Converting to Percentiles and Back (1 of 4)
If the mean and standard deviation of a normal distribution are known, it is relatively easy to figure out the percentile rank of a person obtaining a specific score. To be more concrete, assume a test in Introductory Psychology is normally distributed with a mean of 80 and a standard deviation of 5. What is the percentile rank of a person who received a score of 70 on the test?
Mathematical statisticians have developed ways of determining the proportion of a distribution that is below a given number of standard deviations from the mean. They have shown that only 2.3% of the population will be less than or equal to a score two standard deviations below the mean. (click here to see why 70 is two standard deviations below the mean.) In terms of the Introductory Psychology test example, this means that a person scoring 70 would be in the 2.3rd percentile.
normal distributiion
This graph shows the distribution of scores on the test. The shaded area is 2.3% of the total area. The proportion of the area below 70 is equal to the proportion of the scores below 70.

Former Milwaukee Road system. Solid red lines are trackage still operated by CP Rail; purple lines are trackage now operated by other railroads; red dotted lines are abandoned. This map suggests a rail crossing between Iowa and Wisconsin; this crossing closed in 1961.
The Milwaukee Road, officially the Chicago, Milwaukee, St. Paul and Pacific Railroad (reporting markMILW), was a Class I railroad that operated in the Midwest and Northwest of the United States from 1847 until 1980, when its Pacific Coast Extension was embargoed in the states of Montana, Idaho, and Washington. Its core Midwest system was merged into the Soo Line Railroad on January 1, 1986. The Pacific Coast Extension from the Midwest to the Pacific Northwest, planned between 1901 and 1906 and built between 1906 and 1909, was carried out under the auspices of the Chicago, Milwaukee and Puget Sound Railroad. This corporate entity was folded into its parent company in 1912.

Stigma persists through systematic exclusion of black persons from mobility and resources in society (i.e., structural racism). Residential segregation, like other forms of structural racism, may impair health by hindering access to important resources such as housing, food, health insurance coverage, and governmental benefits. Recent literature has proposed that stigma be considered a fundamental cause of population health inequalities.
We examined the relation between county-level residential segregation dissimilarity indices and various social determinants of health outcomes within Indiana using generalized estimating equation (GEE) modeling. Primary outcomes included housing instability, food insecurity, health insurance status, and enrollment in governmental assistance programs (i.e., Medicaid and SNAP). We used social determinants of health data provided by the Indiana Department of Health collected by Indiana 2-1-1 and residential segregation dissimilarity indices calculated by the University of Wisconsin Population Health Institute.
The GEE models, adjusted for county based on the assumption that subject responses within the same county are correlated, regressed SDOH outcomes against segregation indices. In the adjusted models, we controlled for race and income level. Interactions between residential segregation and race were tested. Residential segregation was significantly associated with housing instability (OR = 1.2916, 95%CI (1.0877, 1.5338), p = 0.0035), food insecurity (OR = 1.1294, 95%CI (1.0292, 1.2394), p=0.0103), and SNAP benefits (OR = 1.1640, 95%CI (1.0559, 1.2831), p = 0.0023). Residential segregation was not significantly associated with health insurance status or Medicaid enrollment.
Structural racism is a fundamental cause of some social determinants of health inequalities. People living in counties with higher residential segregation were found to have significantly higher odds of being food insecure, housing insecure, and receiving SNAP benefits. Insurance status and type were not found to be significant outcomes. State and federal governmental programs and policy changes, paired with anti-stigma campaigns, can be implemented to decrease structural racism and subsequently racial health inequities.

b. Direct labor cost charged to production during the year was
Solution Preview
a. The cost of raw materials purchased during the year:
The problem states that $326 worth of raw materials were used in production, so we know that the total amount of raw materials purchased will be $326 plus or minus the change in raw materials inventory.
Since Raw Material Beginning Inventory was $75 and Ending Raw Material Inventory was $85, then we know that Raw Material Inventory increased by $10. This means that $10 worth of inventory was purchased but not used in production. Since $326 worth of inventory was used in production and $10 was bought but not used in production,...

The interfacial reaction between calcium-bentonite zinc ion was studied by a radioisotopic tracer method. Both the quantity of zinc ions incorporated into the solid and the quantity of calcium ions leaving the solid were determined. A comparison of the two quantities and the Langmuir representation obtained suggest that other processes can occur besides ion exchange. These processes were separated; ion exchange and adsorption isotherms were constructed, and the isotherm parameters determined. The real ion exchange process was evaluated on the basis of the law of mass action as well. The equilibrium constant of the process and the surface activity coefficients of calcium and zinc ions were determined. The variation of the surface activity coefficient as a function of surface concentration is explained by supposing exchange sites of different binding energy.

LibreOffice has an old compatibility issue (inherited from OpenOffice) with Microsoft Office related to text highlighting (character background). During document exchange between the two office suites text highlighting is changed on an unexpected way. The root of the problem is that LibreOffice (LO) and Microsoft Office (MSO) has a different design for character backgrounds and so it's ambiguous how to save LO character background to MSO file formats (ambiguous both to users and to developers). Now this issue is solved by allowing the users to specify the behavior of LO export.
Microsoft Word has a two-character-background concept. One attribute is called shading which lives on more levels of the document model: table cells, paragraphs and characters. With it we can add any background color to the selected object and we also can use it in a theme. The other one is called highlighting which offers a more limited color selection and is used on the analogy of highlighter pen to call attention to a portion of the document.
LibreOffice Writer, in the other hand, supports only one kind of character background which is called also as highlighting. This character background is closer to Word shading attribute, since it has a wider color selection and it's also a specialization of the general background attribute on the same way as shading in Word. An other similarity is that automatic font color interacts with character background in Writer and with shading in Word on a way to make text always visible (e.g. when background is dark then text color becomes white, when the background is light then text color changes to black). Word highlighting doesn't have this kind of behavior.
About Microsoft Word's concept
After I decided to fix this issue the first questions were: How useful is this two-character-background concept of Microsoft Office? Is this something which LibreOffice should support?
I've got the answer: It's not something that LibreOffice needs.
First of all I can't see a real difference between the usage of shading and highlighting in Word. I mean both have the purpose to make some parts of the text more visible (highlight them). Highlighting can be also used for reviewing a document (mark parts of a document temporarily), but both office suits have a Comments feature which includes an integrated highlighting function, which can be more useful for this purpose.
Additonally this concept also leads to misunderstandings among the users. At the first sight it can't be decided whether a highlighted text portion in a document is formatted actually with highlighting or with shading. This becomes worse because of that the highlighting feature is more accessible in some versions of Word and so it is more known by the users as shading which can make users confused when they get a document with character shading. As I see this was the main issue also in case of LibreOffice, because it exported character background as shading to MSO formats and so some of the users were not able to remove this shading in Word by using "Highlight" toolbar button.
Summary, as I see the two-character-background concept does not have a real benefit and also causes problems on the user side so it's not worth to have.
Export as highlighting or as shading
The second question was: How to export LO character background to MSO formats to make the users happy? MSO shading is closer to LO character background in behavior but at the same time highlighting is more accessible in Word and on Writer's user interface character background is called as highlighting. So both attribute can be a good candidate for export.
That's why it seemed the best to have an option to choose between shading and highlighting. I added this option at Tools -> Options -> Load/Save -> Microsoft Office, with which user can specify the behavior of the export. The default became highlighting mainly because in LO character background is called highlighting and so users can expect they will get highlighting in their MSO document and not shading.
|New Microsoft Office compatibility option|
Import of Microsoft Word documents
So far I wrote only about the export of LO character background. The next question is how shading and highlighting are imported from MSO documents and how they saved back. I solved this on the way that both attributes are preserved by import so a Word document will have the same appearance in Writer. If this document is saved without modification, then shading and highlighting will be saved back unchanged.
The difference compared to Word becomes visible by editing. It doesn't matter whether a character background was shading or highlighting in the original document it can be edited by Highlighting toolbar button in Writer. From that point - after a specific text range's background is edited inside LibreOffice - MSO shading and highlighting markers will be removed and will be replaced with LO specific character background. So MSO attributes are preserved until the corresponding text range is edited by LibreOffice.
In the next LibreOffice release users will be able to customize their office suite on one more way by specifying how to export character background to Microsoft Word file formats. I think this is the best we can do here because of the design differences. Well, let's see what users say.

Always wanted to be near the sea, enjoying the sunsets and listening to the sound of the waves? Being on the water has always been associated with wellbeing, and for a reason… or better, six. Here are 6 reasons why sailing will make you, and those around you, happier… and healthier.
1. Negative Ions
Breathing is what keeps us alive, the better the air, the better we fuel our bodies. Fresh air makes us feel more awake, active and alive. When sailing you are exposed to clean, fresh air, away from the polluted air of cities and cars. The sea air is richer in negative ions, which help the body absorb oxygen and make us feel better. They naturalize free radicals, revitalize metabolism and help to purify the blood.
2. Vitamin D
Sailing often means spending more time outdoors, getting the benefits of the sun and charging our bodies with essential vitamin D, which helps our bodies to absorb calcium and phosphorus, essential for our bones. Having said that, when sailing it is also important to protect our skin from too much sun, using protective hats, clothing and sun cream.
3. Sounds of Nature
A form of pollution is the sound pollution that we suffer living in cities or near industrial areas. Whilst sailing, we listen to the waves and sounds of water and the wind in our sails. Nature sounds are relaxing and give us a feeling of calm and wellbeing. How many Spas recreate those sounds with artificial fountains or recordings? Living near the water will get you the real thing.
4. Physical fitness
Being near water reduces stress. It makes us feel physically better and more relaxed and boosts our immune system, allowing us to live a healthier life. Sailing also keeps us active and exercised, with all the benefits that an active life provides.
5. The Blue Mind Effect
Being near the water sets our mind in a relaxed, happier state. Recent studies point out how our brains react when we are near the sea, rivers or lakes, making us feel better mentally. Wallace J. Nichols explores the scientific reason behind this in his book 'The Blue Mind'.
6. Feeling of accomplishment
Learning the skills to sail a boat and being able to sail to your destination gives you a feeling of self confidence and accomplishment. Sailing is a constant learning, helping to keep your mind active.
Well, there you have it…
…6 good reasons why sailing not only will make you happier, but will keep you healthier. So why don't you come sailing with us? Whether you are an experienced Skipper or a total novice, take the helm, learn new skills and enjoy the benefits of sailing.

theta is always negative for long calls and long put

 This is a statement by schweser and also investopedia. How can it be true?
 For long put, the longer the option, the cheaper it may get as the expected price of stock will be higher due to interest and because of this the put will decrease in value?
 What is wrong with my logic?
 2. Theta for a long call is always negative. True.
 However, Theta of a long put always exceeds the theta of a call by a fixed amount. Hence for out-of-money puts, the theta may be positive also.
 Another concept to be aware of, theta is measured in terms of "time remaining to maturity (T-t)" in contrast to "time passed (t)" - thinking in terms of "time passed" may be akin to reversing the sign of theta.

The question is $x = \arctan\frac 23 + \arctan\frac 12$. What is $\tan(x)$?
I'm having trouble figuring out how to calculate the arctan values without a calculator, or do I not even need to find these values to calculate what $\tan(x)$ is? Any help is greatly appreciated (I would show some sort of work, but I am actually completely stuck).
I know that the range of arctan is restricted to $(–90^\circ, 90^\circ)$ or $(-\pi/2, \pi/2)$, but i'm not sure how this helps.
Below is a solution based on right triangles.
enter image description here
Note that $y=\arctan\frac{2}{3}$, and $z=\arctan\frac{1}{2}$. It follows that $x = y + z$.
The question is then: Calculate $\frac{b}{a}$.
Since $a^2 + c^2 = 4$ and $\frac{a}{c} = \frac{2}{3}$, it follows that $a^{2} = \frac{16}{13}$.
Since $a^2 + b^2 = 5$, it follows that $b^2 = \frac{49}{13}$.
Thus, $\frac{b}{a} = \frac{7}{4}$.
The take-away should be that sometimes going to a more basic line of thought can get you unstuck on a problem. Also, this gives some insight on how you can derive the tangent of sums formula.
Use the formula $\tan(a+b)=\frac{\tan(a)+\tan(b)}{1-\tan(a)\tan(b)}$
Let $A=\arctan\frac 23,B=\arctan\frac 12$.
Then, $$\tan x=\tan(A+B)=\frac{\tan A+\tan B}{1-\tan A\tan B}=\frac{\frac 23+\frac 12}{1-\frac 23\cdot \frac 12}.$$

Professor Stuart Macdonald contributes to book on Canadian Churches and WWI
As Professor of Church and Society, The Rev. Dr. Stuart Macdonald's research has focused on changing face of religion, in particular Christianity, in Canada.
His work has been included in a new publication, Canadian Churches and the First World War (Edited by Gordon L. Heath), that is available now. You can purchase the book through its publisher, Wipf and Stock, or through Amazon.
Most accounts of Canada and the First World War either ignore or merely mention in passing the churches' experience. Such neglect does not do justice to the remarkable influence of the wartime churches nor to the religious identity of the young Dominion. The churches' support for the war was often wholehearted, but just as often nuanced and critical, shaped by either the classic just war paradigm or pacifism's outright rejection of violence. The war heightened issues of Canadianization, attitudes to violence, and ministry to the bereaved and the disillusioned. It also exacerbated ethnic tensions within and between denominations, and challenged notions of national and imperial identity. The authors of this volume provide a detailed summary of various Christian traditions and the war, both synthesizing and furthering previous research. In addition to examining the experience of Roman Catholics (English and French speaking), Anglicans, Presbyterians, Methodists, Baptists, Lutherans, Mennonites, and Quakers, there are chapters on precedents formed during the South African War, the work of military chaplains, and the roles of church women on the home front.

 - The VCC pin of the motor connects to the 5V pin of the Arduino. This pin is responsible for providing power to the encoder.
 - For this project, you don't need to connect the motor pins (+ and – terminals) to anything since you will be turning the motor manually with your hand.
Write and Load the Code
Now we're ready to calculate the number of encoder pulses per revolution. Open the Arduino IDE, and write the following program. The name of my program is pulses_per_revolution_counter.ino.
/*
 * Author: Automatic Addison
 * Website: _URL_
 * Description: Count the number of encoder pulses per revolution.
 */
// Encoder output to Arduino Interrupt pin. Tracks the pulse count.
#define ENC_IN_RIGHT_A 2
// Keep track of the number of right wheel pulses
volatile long right_wheel_pulse_count = 0;
void setup() {
 // Open the serial port at 9600 bps
 Serial.begin(9600);
 // Set pin states of the encoder
 pinMode(ENC_IN_RIGHT_A , INPUT_PULLUP);
 // Every time the pin goes high, this is a pulse
 attachInterrupt(digitalPinToInterrupt(ENC_IN_RIGHT_A), right_wheel_pulse, RISING);

}
void loop() {

 Serial.print(" Pulses: ");
 Serial.println(right_wheel_pulse_count);
}
// Increment the number of pulses by 1
void right_wheel_pulse() {
 right_wheel_pulse_count++;
}
Compile the code by clicking the green checkmark in the upper-left of the IDE window.
Connect the Arduino board to your personal computer using the USB cord.
Load the code we just wrote to your Arduino board.
Now, follow the following steps in the image below.
open-serial-monitorJPG
When you open the Serial Monitor, the pulse count should be 0.
2_starting_pulses
Using your hand, rotate the motor a complete 360-degree turn.
Here is the output. We can see that there were 620 pulses generated.
3-ending-pulses
Thus, this motor generates 620 pulses per revolution.
That's it. Keep building!

- Mathematical models for the analysis of neighboring grounding systems are provided.
- Potentially hazardous circumstances arising in various situations are analyzed.
- The transferred potentials to the equipment in open pit mines are determined.
- Approximate expressions for assessing some interference effects are proposed.
The paper develops mathematical models for the analysis of the mutual interference of closely positioned ground electrodes in order to assess the safety risks that might appear in various circumstances often characteristic for urban areas. The potentially hazardous situation that might arise in open pit mines at the equipment grounded by connection with the common ground electrode is also investigated. In the scope of the analysis of possible dangerous circumstances the maximum touch - and step - voltages that appear at the sites protected by the grounding grids are calculated for various distances between the grids and in case of uniform and nonuniform two - layer soil. Approximate expressions for assessing some interference effects are also provided and successfully checked for various cases. Based upon the results of the conducted series of calculations, the safety risks are determined for all investigated cases. It was shown that the highest safety risks can appear in the case when the neighboring grids are unintentionally connected as well as in the case when the neighboring grid is connected with some grounded objects, which is characteristic for urban areas and for open pit mines with common ground electrodes.

The wireless Airpods offered by Apple are being used and loved by millions because they are powerful and innovative. It is easy to carry them around but the chances to lose them is higher as well. However, Apple has made things easier for the ones who lost their products. Through Find My iPhone, Apple has already allowed Apple users to find their iPhone. The same type of service "Find My AirPods" is available for AirPods users to get back their AirPods too. You can easily set up this tool and find the lost Apple AirPods.
For using Find My AirPods, you need to have these things:
* An iOS device operating on iOS 10.3 or higher versions.
* An iCloud account, which must be active.
* Your AirPods needs to be paired with the iOS device that you are using.
* Find My iPhone needs to be enabled before losing your AirPods.
Setting up Find My AirPods
If you have earlier set up Find My iPhone, you must be aware that it is necessary to have an iCloud account. If you've additionally set up your AirPods with your iOS device, you know that through iCloud other device are paired. When it involves finding lost AirPods, it's particularly helpful. It is because you don't need to set up Find My AirPods on its own. As long as you've got an active iCloud account on the iPhone or iPad that you used to set up, and have enabled Find My iPhone on the same, your AirPods are automatically connected to Find My AirPods. Pretty straightforward, right?
How to Access Find My AirPods
You can find your lost AirPods via Find My AirPods by using two things. Either, through an iOS device having Find My iPhone app installed on it or through a PC web browser by logging in to your iCloud account. If you have any one of them, follow the below-given steps for finding you AirPods:
1. Launch the Find My iPhone app in your iOS device or go to iCloud.com in your PC.
2. If you are on PC, sign in with the same account that you accessed to set up the lost AirPods. iOS device users skip directly to the fourth step.
3. Choose the Find iPhone icon on your PC.
4. Once you have done it, Find My iPhone/AirPods will launch and try to find your AirPods. Tap on the All Device section and then choose AirPods. Those who are on an iOS device, tap on the AirPods.
5. You will get to see the AirPods on the map if they will be found. The device that you are using for finding will be seen as a blue dot on the map. When it comes to your Airpods, they will appear as any one of these two colored dots:
* Gray: It means that the AirPods cannot be located due to various reasons. You can check all the reasons at the end of this article.
* Green: It means your AirPods are connected with an iOS device and are online, and you can play anything to find them.
6. If you see the green dot, choose the dot and then hit the "i" icon available in the pop-up.
7. From the pop up that is available on the top section of the screen, click on Play Sound to play something on your AirPods.
8. You will get a few options while playing the sound in your AirPods. First will be Stop Playing option, which will pause the audio. Second, Mute Left option that is going to stop the audio playing on the left AirPod. The third will be a Mute Right option that will prevent the sound that will be playing on the right AirPod.
9. In this way, you can find the lost AirPods easily. If you didn't view the green dot earlier and see a gray dot, it is a problem.
The reasons behind the fact that you are not able to find AirPods are no Find My iPhone, no battery, or out of range. If you didn't set up Find My iPhone/AirPods before you lost the earbuds, you can't find them. The low battery won't let you see them as well. Last but not least, if your AirPods are out of range, they will not be shown to you!

text: 1. The problem statement, all variables and given/known data What is the concentration of the unknown Cu2+ solution? The reaction is Zn(s) + Cu2+(aq) -> Zn2+(aq) + Cu(s). The concentration of Zn2+ is 0.05 M 2. Relevant equations 3. The attempt at a solution I'm coming up with about 2 different answers, and I'm not sure which is correct. Using a graph of (Emf vs log Cu2+) I obtained the line y = -1.0967 - 0.02x and I'm not sure how to figure out the unknown copper concentration. Method 1 (I'm leaning towards this method): -1.08 V is the voltage obtained from the unknown. -1.08 V = -1.0967 - 0.02x x = -.835 10^x = 10^-.835 [Cu2+] =.146 M Method 2: I'm assuming E0 is the y intercept and -0.0592/2logQ is the slope, not positive if that is correct. E = E0 - 0.0592/2logQ Q = [Zn2+]/[Cu+2] -1.08 = -1.0967 - 0.0592/2 log Q [Cu+2] =.183 M Which is the correct method to use for finding the copper concentration?


text: The energy that causes reservoir fluids to flow out of the reservoir rock and into a wellbore. Gravity drive is simply like draining a tank. Gas drive depends on the expansion of the gas in a reservoir to provide the driving energy; the pressure is reduced as the reservoir is produced. Solution gas drive depends on gas coming out of solution in the oil as the pressure is reduced. Water drive depends on water pressure to force hydrocarbons into the wellbore, and depends on the connectivity of the reservoir with a surrounding aquifer. Water drive is much more efficient at driving oil than is gas drive. Natural reservoir drives are supplemented by injecting gas, water, or other substances in secondary recovery and enhanced oil recovery (q.v.).

The Covid-19 pandemic continues to cause headaches across the Greek olive oil sector, with the most recent outbreak potentially leading to labor shortages and decreasing the production of the current season.
Some health experts have even identified the start of early harvesting in Greece as a potential cause for the spread of the novel coronavirus in some regions of the country.
The olive harvest hangs on a knife-edge here.
"There is an increase of the coronavirus cases in areas that were off the map of the highly-affected territories until recently, including Fokida, Messinia, Lesvos and Crete," Vana Papaevagelou, assistant professor of pediatric infectious diseases of Athens University, said during a press conference of the Ministry of Health.
"The outbreak of the virus in these areas may be related to the olive harvest," she added.See Also:2020 Harvest Updates
Due to the fear of contracting Covid-19 and the shortage of workers, the olives in many areas are likely to be left unpicked, ultimately leading to a reduced olive oil yield.
"The uncertainty caused by the pandemic made many producers start harvesting in October, which is too early in the season," mill owner Voula Kaplanis, from the village of Solomos on the Peloponnese, told Olive Oil Times.
"Even so, we get olive oil of high quality since there are no signs of the fruit fly," she added. "But other producers are afraid of becoming infected with the coronavirus and have left their olives unharvested, so many of our clients have not yet shown up to process their crop. No one can tell how things will evolve through January when we wrap our operations up."
Further complicating the matter, a new nationwide lockdown imposed in early November introduced more strict international travel restrictions and a prohibition on travel within the country, hampering the daily commute of growers and the available land workers to the olive groves.
During the lockdown period, growers and producers must be able to prove ownership of the groves, whereas proof of employment is required for workers when traveling to the groves for the harvest.
Furthermore, the sluggish procedures in place for hiring foreign workers were pinpointed by some producers as a cause for the lack of workforce in the country.
"There is a great delay in calling in workers [from abroad]," Kostas Apostolopoulos, the head of the Handrinos agricultural association in Messinia, said. "The pertinent regional offices are being choked by bureaucracy."
"The main part of the harvest is expected to begin in 10 days, and we do not know how the quarantine will impact the travel of land workers and the transportation of the olives from the field to the mill," he added.See Also:Greece Pledges €126M Aid to Producers for Pandemic-Related Losses
Yiannis Ravvas, an olive grower and mill owner based in Fthiotida, in central Greece, was quick to describe a grim harvesting season in the region.
"The olive harvest hangs on a knife-edge here," Ravvas said. "Foreign laborers left when the first Covid-related travel measures were announced, and Greek workers are almost impossible to come by."
"We will get on with the harvest with everything we have. Despite the olive trees being in their natural cycle of a low yield this year, we were expecting a substantial production," he added. "But the ugly truth is that the olive fruits have been heavily affected by the fruit fly, which has spread almost everywhere affecting the quantity and most importantly the quality of our olive oil."
Another significant concern for Ravvas is the price of extra virgin olive oil, which is currently lower than the established prices in other olive oil producing territories of the country.
"Producers' prices here are nothing to write home about, ranging between €2.50 ($2.96) and €2.80 ($3.31) per kilogram and rendering all our hard work and efforts pointless," he said.
"The weird thing is that a couple of nearby big bottling facilities operate 24/7 to fulfill orders from abroad in times of strict measures and closures of many eateries almost everywhere, and I do not really understand how prices at origin are so low given the existing market demand," he added.
However, things look better in some areas of Crete in terms of both the availability of workers and olive oil quality, as the owners of the Despina Blavakis olive oil mill near Heraklion told Olive Oil Times.
"Harvest started in October here and we expect to get olive oil of top quality," the owners said. "There are some workers from Albania available, so the pandemic has not created significant obstacles in getting land laborers so far. And thankfully, the olive fruits are unharmed by the fruit fly, but we have to delay the harvest for some days since it has started to rain heavily in our area."
"One kilogram of extra virgin olive oil currently sells for €2.50 ($2.96), which is really low," they added. "We have already sold some quantities in bulk, but the riddle of low prices and the impact of the Covid-19 pandemic is difficult to solve and we are uncertain about the future."

Four steps for testing housing material performance
When exposed to commonly used aggressive disinfectants and drugs, many materials used in medical devices can crack, craze, discolor, and become sticky. Currently, there are no industry standards for evaluating surface compatibility. That's why Eastman developed a 4-step test method based on ASTM standards to better understand why plastics fail and how different plastics perform in the real world.
 1. Select the appropriate jig.
 2. Load flex bars onto jig.
 3. Apply chemicals to the flex bars.
 4. Perform reverse side impact test.
Step 4 is the differentiating step in this testing protocol. While visual inspection after step 3 may reveal changes in some plastics, there may be cracks or crazes that are not visible to the naked eye or identified by weight or dimensional changes. By performing Step 4, you are better able to predict the reliability of a device after exposure.
Read our Disinfect with Confidence brochure for more details on each step of the process, and check out this video.
Ultimately, this test should help you confidently choose the best material for your next project.

Why should I Hire a Lawyer if there is a Real Estate Agent or a Mediator involved in my House Purchase?
One of the reason is because the Real Estate Agent is not responsible by law for legal issues or urban verifications in the property purchase in Italy.
The Real Estate Agent's responsibility in Italy is limited to the intermediation work linking the buyer and the seller. This task will be carried out through the normal diligence which simple consists in the performance of aforementioned service referred to a broker with medium capacity.
Therefore, he is not responsible if in the closing phase of the notarial deed he didn't informed and alerted the buyer on the fact that the chosen property was subject to urban issues and that issue wasn't allowing its marketability.
The damages requested to the mediator were huge, in addition to the down payment (Caparra) also the damage for the non-purchase of another property that would have been optioned if the promissory buyer had known from the first moment the urban differences.
Therefore, the mediator has the obligation to inform the parties of the circumstances known to him, all those things of which he became aware in carrying out the assignment, and also of all the circumstances that could have been acquired by a mediator with only medium professional skills, with the use of normal diligence. Definitely, not legal skills or obligations.
However, nothing can be claimed about the responsibility of the Real Estate Agent with regards to the control and verification of the mortgage deeds and the urban situation.
The Italian Supreme Court (Corte di Cassazione) has repeatedly reiterated that in the ordinary diligence is not required that the mediator does any of the technical-legal investigations, such as, for example:
 - the mortgage and land registry surveys;
 - the verification of the urban situation;
 - the assessment and the check in the Real Estate Registers;
 - the freedom of the property subject to negotiation from transcripts or prejudicial registrations;
 - or even the urban planning examination.
In this regard, the same Court refers to a very long jurisprudence composed of dozens of sentences that have affirmed the same principle.
Therefore, the Court condemned the promissory purchasers who had turned to the Real Estate Agent to be compensated for damages above mentioned because of the differences found they could not be part of that level of elementary knowability for which the estate agent would not provide justifications based on his personal lack of knowledge.
Different fate would have had in the case in which the mediator received an express assignment from the promissory buyer (with specific and more expensive remuneration, different from the commission) to carry out mortgage-cadastral or urban planning surveys, his obligation to fulfill the task is clearly outlined, and he could have civil responsibility in the hypothesis that the job was not well done.
It follows that if Real Estate Agents do not check the urban situation, they have no responsibility whatsoever, except that they have failed to communicate the information known, or in any case elementary diligence, while if the Estate Agents received an express assignment with specific and more expensive remuneration he has to provide information of a mortgage-cadastral or urbanistic nature assuming the particular responsibilities of the case, but still he is not a legal professional.
In conclusion, prudence requires to abstain from reckless steps and to delegate everything related to your real estate transactions in Italy to a professional Trusted Lawyer.

Nominal model for the optical response of a chiral sculptured thin film infiltrated by an isotropic chiral fluid-oblique incidence
J. A. Sherwin, Akhlesh Lakhtakia
Research output: Contribution to journalArticle
10 Scopus citations
Abstract
Numerical calculations on the response of a nonaxially excited chiral sculptured thin film (STF) infiltrated with a chiral fluid are presented. The effects of the constitutive and microstructural parameters on the optical response of the chiral STF are explored. Two Bragg regimes manifest themselves when the chiral STF is excited nonaxially. Infiltration of a chiral STF with a chiral fluid can either blue- or red-shift the spectral location of one Bragg regime, but the shift of the spectral location of the other Bragg regime is largely indifferent to the chirality of the fluid. The model also predicts that the chiral fluid can either enhance or diminish the optical activity exhibited by the chiral STF within either manifested Bragg regime. Which of these effects occurs depends on the microstructural and constitutive properties of the chiral STF as well as the constitutive properties of the chiral fluid. The angle of incidence of the plane wave also effects the response of the chiral STF.

"Joy to your soul" reads a note next to a newspaper clipping in a scrapbook belonging to Joy McLean Bosfield (_PHONE_), a musician, educator, and entrepreneur who called Washington, DC home between 1962 and 1985. Joy is a consistent theme in two scrapbooks that she donated to the Anacostia Community Museum. Photos, plane tickets, programs, posters, and poetry chronicle a musical career that took her from New Jersey to Broadway, and then around the world in the 1940s and 1950s. Additional materials from later in her career include a long letter to curator Portia James. Her editorial expertise is evident in lyrical and sometimes funny explanations of how elements of her story connect.

Technical Report Number
We present a surface reconstruction technique that constructs a smooth analytic surface from scattered data. The technique is robust to noise and both poorly and non-uniformly sampled data, making it well-suited for use in medical applications. In addition, the surface can be parameterized in multiple ways, making it possible to represent additional data, such as electromagnetic potential, in a different (but related) coordinate system to the geometric one. The parameterization technique also supports consistent parameterizations of multiple data sets.

Development of a Sulev Capable Technology for a Full Size Gasoline Pfi V8 Passenger Car 2001-01-1314
A full size V8 demonstrator was developed to exhibit technology required to target LEV II emission levels. The testing involved the system integration of a vacuum-insulated catalytic converter (VICC) technology, air gap exhaust components, optimized catalyst loading and control system and calibration. The development strategy utilizes the vacuum insulation, phase-change thermal storage capacity, and cold start calibration strategy to enable the catalyst to quickly reach light-off in 6 seconds over the FTP-75. All emission testing was conducted with two LA4 preparation cycles. This approach is able to reduce the heat loss of the catalytic converter brick during a 12 hour soak period and optimize the calibration warm-up strategy to reduce the amount of emissions during the first 60 seconds of the FTP-75.
The vehicle used for the demonstration was a BMW 540I application. The modifications to the vehicle were limited to the control system, engine calibration and aftertreatment. The strategy used can be applied to light and heavy-duty on-road applications to optimize tailpipe emissions levels. The vehicle also meets nominal driveability requirements over the FTP-75 temperature ranges.

A character in Guild Wars primarily refers to the in-game avatar that the player controls and guides through the game. The term can also be used to refer to the non-player characters that are controlled by the game's AI.
Each game account comes with four initial character slots. As additional campaigns are purchased, the number of slots increases by two. For an owner of all three campaigns, that person will have eight character slots in total. Players can also acquire additional character slots from the Guild Wars In-Game Store for a fee. The current maximum slots purchasable is 26.
|The Guild Wars 2 Wiki also has an article on Character.|
Character creation takes players through a sequence of options that determine the character's appearance and function. An empty character slot is required to undergo this process.
- PvP-only character or roleplaying character: Where the character will be able to play. PvP-only characters begin at maximum level, but are restricted from PvE.
- Campaign: Decides the character's lineage as well as their starting point in PvE.
- Primary Profession: This will determine the character's primary attribute and starting skills. For PvE, this also determines the beginning tutorials.
- Gender: Choose the character's sex. This will affect armor and appearance options.
- Appearance: Choose the face, skin tone, hair color, and hairstyle of the character.
- Height and Armor: Choose the height of the character, as well as the color(s) of his/her starting armor.
- Name: Choose a name. Names must follow ArenaNet's Naming Policy, not be currently in use, or be a single word.
After all of these choices have been made, the character will be created. PvP characters will begin at the Great Temple of Balthazar and PvE characters will begin at their respective campaign tutorial areas: Ascalon, Shing Jea Monastery, or Istan.
A character's physical features or appearance can be altered after the character's creation:
- Many different kinds of armor and weapons can be acquired by characters as they advance in the game.
- Gender, height and appearance can be changed by Anatomical Engineer Llye with Makeover and Extreme Makeover Credits.
- A character's name change can be purchased from the official Guild Wars Online Store.
In order to delete a character, players must head to the character selection screen, select the character they would like to be deleted and press the "Delete" button (default hotkey "D"). To help prevent accidental deletion of a character, players are also required to enter the character's name into a dialogue box, and then press the "Delete" button (or "Enter" on the keyboard). Once a character has been deleted, their progress as well as all of their belongings that they were carrying (including that of their heroes) will also be deleted. Deletion is permanent and cannot be reversed.
Players are automatically given a name reservation lasting 24 hours after the character's deletion. This allows players to create a new character with the same name without someone else taking it in the process.
Be aware that customized items are tied to the character themselves, and not the character's name. Deleting a character and then remaking it with the same name will not grant access to the previously deleted character's customized items.

With the aid of lasers, researchers have developed various two-photon absorption (2PA) based applications, which include biological imaging, 3-dimentional microfabrication, frequency up-converted lasing, optical power limiting, and photodynamic therapy etc. Unlike 2PA, five-photon absorption (5PA) related phenomenon, is more difficult to observe due to the low transition probability of the 5PA process. Furthermore, the realization of five-photon pumped stimulated emission will be even more difficult because it requires the 5PA to be large enough for creating population inversion in the gain medium.
Prof. Zheng Qingdong's group at Fujian Institute of Research on the Structure of Matter, Chinese Academy of Sciences (FJIRSM) has reported on the first experimental observation of five-photon induced stimulated emission in collaboration with Prof. Chen Xueyuan's group at FJIRSM.
By rational molecular design, a multi-photon absorbing material IPPS with the molecular configuration of Donor-Pi-Acceptor was prepared and selected from a large number of multi-photon active chromophores. Through simultaneous five-photon absorption, stimulated emission from IPPS was realized for converting the 2100nm invisible infrared laser into the visible 501nm blue-green laser.
At the same time, by direct three-photon absorption, the IPPS system exhibited a high net conversion efficiency of 10.4 percent, which thus enable the realization of novel frequency up-converted lasing in practical device applications. The results have been published in Nature Photonics.
This work is the first real application for five-photon absorption, which belongs to a ninth-order nonlinear process with extremely low probability. For the 5PA process, its 5th-order dependence on the input light intensity would provide a much stronger spatial confinement so that a much higher contrast in imaging can be achieved as compared to lower-order nonlinear absorption.

2 runners(Alice, Bob) are running on the oval track at a constant speed. The tracklength is 200 meters.
First Alice ran with such low speed that Bob passed him every 2 minutes. To run faster than Bob, Alice sped up 2 times and now she is passing him every 6 minutes. What speed did Bob ran at in km/h?
How much was Bob faster than Alice at first speed?
1/30h is 2 minutes x km/h * 1/30h = 0.2km x = 6km/h
How much was Alice faster than Bob at second speed?
1/10h is 6 minutes 2x km/h * 1/10h = 0.2km x = 1km/h
Don't know how to create equation out of this.

A WHO Meeting on the Promotion and Development of Traditional medicine was held in Geneva from 28 November to 2 December 1977. The consultation was convened in response to the considerable interest evinced in traditional medicine at the Thirtieth World Health Assembly in 1977 and in the subsequent requests by Member States for technical collaboration in organizing educational and research activities in this field.
The aim of the Meeting was to assemble expert representatives of the major systems of traditional medicine to work together and suggest a plan of action to promote and develop various aspects of traditional medicine.
The specific objectives were to make practical suggestions on policy guidelines for the provision of materials and techniques, collaboration among different systems of health care, health education of the public, manpower development, organization of health services, the future development of traditional medicine and its utilization, particularly in the national health services, and relevant research.
A major problem for special consideration was the effective collaboration of different practitioners and their integration into an overall national health care delivery system.
The theme of the Meeting was "Promotion and development of traditional medicine". This report follows the discussion at the Meeting and includes sections on:
- Traditional medicine in health care
- Reasons for the promotion of traditional medicine
- Utilization of traditional medicine in national health care systems
- Integration of traditional medicine and modern medicine
- Manpower development for traditional medicine
- Research promotion and development in traditional medicine


"The term bisbigliando (Italian, 'whispering'; abbrev. Bisbigl. or bisb.) indicates an unmeasured rapid tremolo between two or more strings played quietly in the middle and upper registers of the harp." [p.360, Gould2011
A bisbigliando is played with both hands by plucking the interval or chord, one note after the other, rapidly, lightly and continuously. The playing technique of a bisbigliando is quite different to the normal playing technique. Normally the harpist would first place the fingers on the string, then press them and then release to create a full sound. When playing a bisbigliando, the harpist hardly places the fingers on the strings before playing. He/She plucks the strings very fast and lightly to minimize buzzing and to create a continuous sound. Bisbigliando is a quiet effect, since its production does not allow enough muscle strength for a full sound.
Due to its production a bisbigliando is a quiet effect, however the whispering sound carries well, provided that it is not obscured by thick instrumentation from accompanying instruments.
A bisbigliando is notated as a tremolo chord with the term Bisbigliando written above or below. If the bisbigliando label is omitted, the harpist might play a measured repetition of the chord instead of a bisbigliando. [Gould2011
Bisbigliando, both hands play the same chord:
Bisbigliando, the hands play alternating chords:
The direction of the bisbigliando can be notated with arpeggio lines placed before each cord. If no direction is given the harpist will play each chord upwards, starting from the lowest note in each hand.
If a specific order of notes is wanted the bisbigliando must be notated out in full:
Both Luciano Berio and Toru Takemitsu use the following notation to indicate a random bisbigliando. The notated pitches should be repeated rapidly and continuously in a random order.
Additional remarks
A bisbigliando can also be produced with one hand, however, its speed will be diminished by a considerable extent. Due to the low speed the resulting sound is less continuous and the notes will be perceived rather as a fast repetition of a sequence than as a bisbigliando whisper.

Explanation of distance-calculation, overview
The distance-calculation of today (before PostGIS 1.5) is investigating every combination of vertexes and every combination of vertex against edge in the two geometries inputed. If there is many vertexes this procedure is very heavy and slow. I have tried to find a way to narrow the distances calculated. The idea is only applicable on geometries not intersecting. Hopefully there will come up some good idea how to solve that. Until then the easiest is to check for intersecting bounding boxes (of subgeoms) and if thats the case pass it back to the old calculation.
Here I will try to explain the idea in a good way. Here is two polygons that we want to calculate the smallest distance between.
We start by finding an appropriate line between the polygons. The best one is the line between the center of the bounding boxes.
Now we want to find how every vertex is placed along this line. We illustrate this with two perpendicular lines describing p5 in polygon1 and p12 in polygon2.
Where those lines cross the x-axis gives us a value of where the points is situated along the line. We store that value for each vertex and order the vertexes by this value. P5 in polygon1 has the highest value of polygon1 and p12 has the lowest of polygon2. The first distance we calculate is between those two points. Because we not will calculate the points in ring order we have to also check the edge before and after, so we are testing polygon1 p4, p5, p6 against p11, p12, p13. That calculation will give us a shortest distance between p6 in polygon 1 and p13 in polygon2.
We now know that the distance we are searching is somewhere between the distance between the two parallel lines and the distance that we we have found between the points p6 and p13.
Now we take p5 from polygon1 and measure that to the points in polygon2 in order from closest to the line to more far away. We continue til we have reached the point that is that far from the left line like the shortest distance we have found that far. Then we take the next point in polygon1, p8 that is the point next closest to the line and do the same procedure, measuring against each point in polygon2 until we are «out of reach» for the already found shortest distance. This way we continue until the next point in polygon1 we are picking up is more far away from the right of the parallel lines than the shortest distance we have found. Then there can be no shorter distances to find. As mentioned earlier every check between two points include checking the point before and the point after including the edges in between.
The result is a distance calculated like described by this line from st_shortestline.
The gain from this process is that we don't have to iterate through all point. But as shown every point we actually investigate needs more calculations than todays functions because we have to search both forward and backward for each calculated point. Maybe, because of this it is wise to just use this method if the number of vertexes is more than 20 or something like that.
How this is done
This calculation is implanted instead of the array_array function when there is no intersection.
I don't know if the letters used is international but to describe a function of a line I here use y=k*x + z
The steps are:
- Find bounding box for the two point arrays
- Check if bounding boxes intersecting. If so, send to old function
- Find center of bounding boxes and calculate deltax and deltay from the two points
- Calculate the "z" value from y=kx+z for each vertex with k-value from the slope between the two bbox-center points. To eliminate problems with dividing with zero and other limitations when getting closer to dividing with zero we instead change the x-axes with the y-axes by "mirroring" the coordinate system. In that way the "z"-value represents a lines crosspoint to the x-axes instead of the usual y-axes crossing. Hope it is understandable since I don't know the terminology, but it works :-)
- Now we have a list with all vertexes with this calculated "z"-values together with the ordering-value from the geometry-array.
- We order this list by the calculated "z"-value
- Now we take the two points from our list that is most close to each other according to this "z"-value and calculate the distance between them. We translate the distance value so it will be comparable with our "z"-values
- Now, we start the iteration through the vertexes. We iterate in the z-value order, which means we compare points close to the other geometry according to our z-values before we compare the values more far away. We also stop the iteration at ones the next vertex is more far away from the other geometry than our smallest found distance so far. This will narrow the search for each new mindistance we find.

Musée des Appalaches to unveil a new exhibit on November 10 | Community
NORRIS – The Museum of the Appalachians, a museum affiliated with the Smithsonian, will soon unveil a recently restored Arnwine cabin as part of a new exhibit about the construction of the Norris Dam of TVA and the people who were forced to relocate from the area to which the dam has been built.
The exhibition is entitled âThe sacrifice and renewal of mountaineersâ.
The exhibit features historical photographs and an animated map of the area before and after the construction of the Norris Dam, highlighting the location of the houses, farms, churches and schools that now lie at the bottom of Lake Norris. But the centerpiece of this exhibit is the Arnwine Hut, a house that was once considered the smallest structure in the National Register of Historic Places. Built in 1800 on the banks of the Clinch River at Liberty Hill, the construction of the Norris Dam required the deconstruction and relocation of the Arnwine Hut. Such a house is a prime example of early Appalachian life before the construction of the Norris Dam.
âThis exhibit is a testament to the diligent and industrious people who built this incredible dam, and also to the sacrifice of a people who left their lives behind for the promise of progress,â said museum president Elaine Meyer. âWe are delighted to be able to share this story with visitors from all over the world. "
In the fall of 1933, at the height of the Great Depression, the Tennessee Valley Authority embarked on its first major project, the construction of the Norris Dam. This engineering phenomenon took several years and thousands of workers, ultimately providing flood control and electrical power to an entire region.
The Appalachian Museum is located at 2819 Andersonville Highway in Clinton and is open daily from 9 a.m. to 5 p.m. For more information, visit museumofap palachia.org or dial _PHONE_.

Early stages as far as how I'd use this with students but definitely some fun math to investigate here through Desmos related to generating pythagorean triples in a coordinate grid.
Things I notice:
When gcd(m,n) = 1 we have the primitive pythagorean triple, when gcd(m,n) > 1 we get a triple similar to a primitive triple.
Things I wonder:
How could I get spirals to show up in desmos like those in this wikipedia article?

Pitcher's Thistle (Cirsium pitcheri)
By Morty Harwood
Pitcher's thistle, or dune thistle, occurs along the shores of Lake Michigan, Huron, and Superior. Originally discovered around 1820 by Dr. Zina Pitcher in what is now Pictured Rocks National Lakeshore, this small thistle grows to a maximum height of about three to four feet when flowering, considerably less that the size reached by its larger cousin Canada thistle (C. arvense). A native of the Great Lakes dune ecosystem, it thrives in sandy soil with the help of an impressive taproot (up to six feet long!) that helps the plant obtain water. For much of its life the Pitcher's thistle exists as a small, inconspicuous cluster of leaves called a rosette, the massive taproot encompassing a majority of the plants mass. Flowering occurs after the Pitcher's thistle survives in this rosette stage for up to eight years. After flowering and producing seed, the plant dies.
Pitcher's thistle can be identified by its deeply toothed, wooly leaves and by the presence of spines at the tips of each point on the leaf. The wooly coating gives the leaves and stems their characteristic silvery appearance, as well as helping the plant to conserve water. The plant flowers from mid-June through September and shows a flower head that ranges from creamy white to light pink. This trait can be helpful in distinguishing it from other, more common thistles, which typically possess pink or purple flowers. Other varieties of thistle also lack the extremely wooly leaves and silvery appearance of the Pitcher's Thistle.
From an ecological perspective, all thistles are important food sources for certain birds, especially American Goldfinches, which may feed on thistle seed almost exclusively during later summer and early fall. Small mammals such as ground squirrels may also consume the seeds after they have fallen from the plant.
Although it was likely never extremely widespread, Pitcher's thistle was once fairly common in sand dune ecosystems of Michigan, Wisconsin, Indiana, Illinois, and the Canadian province of Ontario. Numbers of Pitcher's thistle, however, have declined in recent decades due to habitat destruction associated with development and recreational use. The sensitivity of the Pitcher's thistle to these types of disturbances led to its designation as a federally threatened species in 1996. A threatened species is a species that is at risk of becoming endangered, while an endangered species is one that is at risk of becoming extinct. Pitcher's Thistle is also protected at the state level in each state where it occurs, and at both provincial and national levels in Canada. Due to continued development and overuse of the sensitive Great Lakes sand dune ecosystem, there is still a risk to the Pitcher's thistle and other native plants sharing this habitat. Invasive plants species – particularly spotted knapweed – also pose a threat to the habitat of the Pitcher's thistle. Recently, concern has arisen that the non-native beetle species Rhinocyllus conicus may be praying on Pitcher's thistle. This beetle preys on the flower heads of the plant, and was originally introduced to control populations of non-native thistles.

OBJECTIVE: Four experiments were conducted in order to assess the effectiveness of dynamic vibrotactile collision-warning signals in potentially enhancing safe driving. BACKGROUND: Auditory neuroscience research has demonstrated that auditory signals that move toward a person are more salient than those that move away. If this looming effect were found to extend to the tactile modality, then it could be utilized in the context of in-car warning signal design. METHOD: The effectiveness of various vibrotactile warning signals was assessed using a simulated car-following task. The vibrotactile warning signals consisted of dynamic toward-/away-from-torso cues (Experiment 1), dynamic versus static vibrotactile cues (Experiment 2), looming-intensityand constant-intensity-toward-torso cues (Experiment 3), and static cues presented on the hands or on the waist, having either a low or high vibration intensity (Experiment 4). RESULTS: Braking reaction times (BRTs) were significantly faster for toward-torso as compared to away-from-torso cues (Experiments 1 and 2) and static cues (Experiment 2). This difference could not have been attributed to differential responses to signals delivered to different body parts (i.e., the waist vs. hands; Experiment 4). Embedding a looming-intensity signal into the toward-torso signal did not result in any additional BRT benefits (Experiment 3). CONCLUSION: Dynamic vibrotactile cues that feel as though they are approaching the torso can be used to communicate information concerning external events, resulting in a significantly faster reaction time to potential collisions. APPLICATION: Dynamic vibrotactile warning signals that move toward the body offer great potential for the design of future in-car collision-warning system.
