How to Strip Wire Fast & Efficiently
The wires and cables are often insulated with a plastic or other non-heat or non-electrical conducting material. In order to use the wires, the insulation has to be stripped off.
Stripping wire fast is a bit tricky. There are a number of ways of stripping the insulation from the wires.
Some of the methods are fast whereas some are considerably slower. Some are more effective than others are.
The method you choose to strip your wires will depend on the wire length, size, and the quantity of wires you have to strip.
The method you choose will also be determined by the reason why you want to trip the wires in the first place. Whether it is for household use of resale.
The following are the options you have to strip your wires. The methods are discussed from the least effective to the most effective.
6 Ways to Strip Wire Fast
1. The sun warming method
You can only use this method when there is a bright sunshine that is quite hot. This is only possible during the summer.
Since most insulation is made of plastic, putting the wires out in the hot sun could help soften the plastic. This makes it easier to pull it off.
Once the wire is hot and soft enough pull the insulation to strip off the wire. However, the method might not effective for thick cables and wires that are heavily insulated.
The sun warming method can be used alongside other methods such as cutting or with a manual wire stripper.
2. Boiling method
You will need the following items to strip wires using this heating method.
 - A metal barrel
 - Water
 - Firewood
The first method you can use to remove plastic insulation from your cables are heating. To use the heating method you need a metallic barrel, water, and firewood.
 - Boil the water in the barrel and dip the insulated wires in the boiling water. This should be done outdoors or open area.
 - Let the wire sit in the boiling water for approximately 10 minutes or more.
 - Remove the wire and pull it to slide off the insulation. You should do this as soon as you remove it from the water before it gets cold and stiff again.
Care should be taken not to burn or scald. The heating method is not very effective when scraping thicker wires. Furthermore, the boiling process may release fumes that are toxic and not good for your health.
You should not burn the insulated wires to get the cables.Burning plastic cables pollutes the environment. This could get you in trouble with the law. Burning also destroys the wires and reduce their quality.
3. The cutting method
These the items you will need for this method.
 1. Cutting blade
 2. Thick gloves
The knife or the cutting blade you choose should be very sharp. You should wear thick gloves to protect you from cuts and bruises from the cutting. This method can be reasonably used only if you have a few wires to strip.
This method is easy to apply and the materials are readily available. However, you can only strip a few cables at a time. It is quite slow.
The process of cutting to strip a wire off start with marking the point or length you want to strip. Then hold the knife or the cutting blade you have over the market spot. Press on it and turn the wire.
When you turn the wire, the cutting blade cut through the insulation. Be careful to press it a little bit light so as not to cut the wire inside. Once you see the wire, grip the end of the cable and pull the insulation off. You can grip it with pliers or hand.
4. Using a homemade tabletop wire stripper
Items you need are:
 - Wooden board
 - Pliers
 - 2 Screws
 - Cutting blade
 - Gloves
There are many methods to make a tabletop wire stripper at home. This is one of the easiest to make. You can easily make this yourself at the garage using the items listed above.
See Also: Best electrician tool belts
The homemade stripper can come in handy when you have a couple of wires to strip. You can easily make this yourself at the garage using the items listed. Follow the video at the link below to make one.
5. Using a manual wire stripper
This is one of the faster methods to strip wires and cables. Especially if you have many wires to strip. They are mainly tabletop but manual.
They do not use electricity. There are many wire strippers on the market and you can purchase one depending on your usage and budget.
The manual wire strippers are operated by hand using a hand-held motor and they are fixed with adjustable blades. The blades can be changed after some time if the initial ones become dull.
6. Using the electric wire stripper
Electric wire strippers are the best. They are most effective when you need to strip a great bulk of wires.
The electric wire strippers are a little more costly than the manual wire strippers are. They are a good investment if you want to strip wires for sale or for other commercial purposes. They are mostly used by scrap metal dealers but you can also purchase for home use.
You will need to read all the instructions of the machine before using. It is effective for stripping all types and sizes of wires.
Final Verdict
As mentioned before the method you will choose to strip wires will depend on the size, length, and quantity of the wires. However, you can combine methods to strip wires fast.

Started in 1879, Holt Cemetery is a potter's field cemetery in New Orleans. It is filled with vernacular headstones. At 7 acres, it is a small, densely packed cemetery. It is still active. When I visited, they were preparing for another funeral.
There are so many amazing monuments at Metairie Cemetery in New Orleans. This is one of the art deco ones to memorialize Charles F Beck (_PHONE_). Whenever a hurricane makes landfall, I always wonder how much more the city can endure. It is a city of resilience, so I would never count it out.
Josie Arlington was a well-known madam in New Orleans. Before her death, she purchased this plot in Metairie Cemetery and commissioned to have this tomb built. Upon her death, she was briefly interred and then removed to an unknown burial plot when her family fought over her estate.
Jose Morales, a local lawyer, bought the tomb for his wife and children. This stirred controversy among community members, and her tomb attracted attention. At one point, a red light was installed close to her tomb and it looked like the tomb was on fire. The light was later removed.
To date, the Metairie staff have not revealed where Josie is buried.

text: Exact or similar copies of code fragments in a code base are known as code clones. Code clones are considered as one of the serious code smells. Stability is a widely investigated perspective of assessing the impacts of clones on software systems. A number of existing studies show that clones are often less stable than non-cloned code. This suggests that clones change more frequently than non-cloned code and thus may require comparatively more maintenance efforts. Again, frequent changes to clones may increase the likelihood of missing change propagation to the co-change candidates leading to inconsistencies or bugs. However, none of the existing studies investigate whether stability of clones is related to the bug-proneness. In this paper, we present an empirical study that analyzes the relationships between stability and bug-proneness of clones. We identify bugfix commits by analyzing the commit messages from software repositories. We then identify the clones those are changed in the bug-fix commits as bug-prone clones. We then compare the stability of buggy and non-buggy clones considering the finegrained syntactic change types and their significance. Our experimental results based on five open-source Java systems of different size and application domains show that (1) stability and bug-proneness of code clones are related and this relationship is statistically significant, (2) for both exact (Type 1) and near-miss (Type 2 and Type 3) clones, buggy clones tend to have higher frequency of changes than non-buggy clones, (3) the bug-proneness of Type 2 and Type 3 clones tend to be strongly related with their stability compared to Type 1 clones, and (4) the relation between the stability and the bug-proneness of clones with respect to fine-grained change types is likely to be influenced by the changes of low to medium significance. We believe that our findings are important and potentially useful in identifying and prioritizing candidate clones for management.

Design of Windmill for Pumping Water
Project Overview
Power generation is a major requirement nowadays, Saudi Arabia in specific is looking for new methods to find renewable energy sources as part of 2030's vision and wind power was found to be suitable for the country's geographic condition.
Wind is the motion of air that is moving on the surface of the earth, and its speed varies based on the geographical location. The wind energy can be generated from the change of atmosphere unevenly where some parts get warmer than others. The warmer air rises and the colder air patches blow to replace them, therefore, alternating air is resulted and that air is wind [1]. Windmill is a mill that is used to convert kinetic energy of the wind into a mechanical energy by using blades rotor assembly which drives the shaft. The result from the rotating shaft provides a mechanical work that can be used to pump water as an example.
This project is intended to design a windmill based on the various components and their actual drawings. This design will contain the rotor assembly i.e. blades, hub, transmission shaft, the gear box, tower, generator, and yow system. Windmill has two different designs, the first type is horizontal and the second type is vertical. In this project, it will focus on the horizontal type. The consumption of power in Saudi Arabia is about triple times the world average [2]. There comes the benefit of windmill as it will reflect positively on the country in an economical point of view, as vision 2030 tries to find an alternative power source other than petroleum. Using renewable energy sources will not only benefit Saudi Arabia economically, but also will help the country to reduce its pollution by using free green energy such as wind. The main advantage of windmill compared with solar panel is that the country is located in a desert area where dust is very common, the dust has a big impact on the solar panels. Moreover, solar energy only works during the day while, windmill can operate 24 hours depending on the wind changes [4]
Project Objectives
The main objective of this project is to determine the power from a renewable energy source which is the wind. Moreover, to design a windmill with the key characteristics of a windmill. Another objective of this project is to practice and apply the engineering concepts. But there are more objectives, which are:
 - Design and construct a windmill to produce a renewable energy which is going to decrease the pollution.
 - Reduce the cost and energy of pumping water.
 - Study the difference between horizontal axis wind turbine, and the vertical axis turbine.
 - Learn the advantages and disadvantages of windmill.
 - Identify mathematical equations.
 - Compare between theoretical and experimental power.
Final Report


we can reconstruct some appropriate climate by interpolating. Atlantis, on the other hand, is the middle of the ocean, and so there is no information on what the climate might have been before became submerged (assuming it ever existed…). Note that nn_interpol = TRUE is the default for this function.
Sometimes, we want to get a time series of climatic reconstructions, thus allowing us to see how climate changed over time:
locations_ts <- location_series(
 x = locations,
 bio_variables = c("bio01", "bio12"),
 dataset = "Example"
)
The resulting dataframe can be subsetted to get the time series for each location (the small Example dataset only contains 5 time slices):
subset(locations_ts, name == "Iho Eleru")
#> name longitude latitude time_bp bio01 bio12
#> 1 Iho Eleru 5 7 -20000 22.55133 1577.238
#> 1.1 Iho Eleru 5 7 -15000 23.27008 1850.715
#> 1.2 Iho Eleru 5 7 -10000 25.34670 2204.595
#> 1.3 Iho Eleru 5 7 -5000 25.65009 2109.735
#> 1.4 Iho Eleru 5 7 0 26.77033 1840.845
Also note that for some locations, climate can be available only for certain time steps, depending on sea level and ice sheet extent. This is the case for Oronsay:
subset(locations_ts, name == "Oronsay")
#> name longitude latitude time_bp bio01 bio12
#> 4 Oronsay -6 56 -20000 NA NA
#> 4.1 Oronsay -6 56 -15000 NA NA
#> 4.2 Oronsay -6 56 -10000 6._PHONE_.824
#> 4.3 Oronsay -6 56 -5000 8._PHONE_.253
#> 4.4 Oronsay -6 56 0 8._PHONE_.490
We can quickly plot bio01 through time for the locations:
library(ggplot2)
ggplot(data = locations_ts, aes(x = time_bp, y = bio01, group = name)) +
 geom_line(aes(col = name)) +
 geom_point(aes(col = name))
#> Warning: Removed 12 rows containing missing values ('geom_line()').
#> Warning: Removed 12 rows containing missing values ('geom_point()').
As expected, we don't have data for Atlantis (as it is always underwater), but we also fail to retrieve data for Chalki. This is because location_series does not interpolate from nearest neighbours by default (so, it differs from location_slice in behaviour). The rationale for this behaviour is that we are interested in whether some locations might end up underwater, and so we do not want to grab climate estimates if they have been submerged. However, in some cases (as for Chalki) it might be necessary to allow for interpolation.
Pretty labels for environmental variables can be generated with var_labels:
library(ggplot2)
ggplot(data = locations_ts, aes(x = time_bp, y = bio01, group = name)) +
 geom_line(aes(col = name)) +
 geom_point(aes(col = name)) +
 labs(
 y = var_labels("bio01", dataset = "Example", abbreviated = TRUE),
 x = "time BP (yr)"
 )
#> Warning: Removed 12 rows containing missing values ('geom_line()').
#> Warning: Removed 12 rows containing missing values ('geom_point()').
Note that these climatic reconstructions were extracted from the Example dataset, which is very coarse, so they should not be used to base any real inference about their environmental conditions. But note also that higher resolution is not always better. It is important to consider the appropriate spatial scale that is relevant to the question at hand. Sometimes, it might be necessary to downscale the simulations (see section at the end of this vignette), or in other cases we might want to get estimates to cover an area around the specific location (e.g. if we are comparing to proxies that capture the climatology of a broad area, such as certain sediment cores that capture pollen from the broader region). location_slice and location_series can provide mean estimates for areas around the location coordinates by setting the buffer parameter (see the help pages of those functions for details).
Get climate for a region
Instead of focussing on specific locations, we might want to look at a whole region. For a given time step, we can extract a slice of climate with
climate_20k <- region_slice(
 time_bp = -20000,
 bio_variables = c("bio01", "bio10", "bio12"),
 dataset = "Example"
)
This returns a raster (technically a SpatRaster object as defined in the terra library, meaning that we can perform all standard terra raster operations on this object). To interact with SpatRaster objects, you will need to have the library terra loaded (otherwise you might get errors as the correct method is not found, e.g. when plotting). pastclim automatically loads terra, so you should be able to work with terra objects without any problem:
climate_20k
#> class : SpatRaster
#> dimensions : 150, 360, 3 (nrow, ncol, nlyr)
#> resolution : 1, 1 (x, y)
#> extent : -180, 180, -60, 90 (xmin, xmax, ymin, ymax)
#> coord. ref. : lon/lat WGS 84
#> sources : example_climate_v1.3.0.nc:BIO1
#> example_climate_v1.3.0.nc:BIO10
#> example_climate_v1.3.0.nc:BIO12
#> varnames : bio01 (annual mean temperature)
#> bio10 (mean temperature of warmest quarter)
#> bio12 (annual precipitation)
#> names : bio01, bio10, bio12
#> unit : degrees Celsius, degrees Celsius, mm per year
#> time (years): -18050
and plot these three variables (the layers of the raster):
terra::plot(climate_20k)
We can add more informative labels with var_labels:
terra::plot(climate_20k,
 main = var_labels(climate_20k, dataset = "Example", abbreviated = TRUE)
)
It is possible to also load a time series of rasters with the function region_series. In this case, the function returns a SpatRasterDataset, with each variable as a sub-dataset:
climate_region <- region_series(
 time_bp = list(min = -15000, max = 0),
 bio_variables = c("bio01", "bio10", "bio12"),
 dataset = "Example"
)
climate_region
#> class : SpatRasterDataset
#> subdatasets : 3
#> dimensions : 150, 360 (nrow, ncol)
#> nlyr : 4, 4, 4
#> resolution : 1, 1 (x, y)
#> extent : -180, 180, -60, 90 (xmin, xmax, ymin, ymax)
#> coord. ref. : lon/lat WGS 84
#> source(s) : example_climate_v1.3.0.nc
#> names : bio01, bio10, bio12
Each of these sub-dataset is a SpatRaster, with time steps as layers:
climate_region$bio01
#> class : SpatRaster
#> dimensions : 150, 360, 4 (nrow, ncol, nlyr)
#> resolution : 1, 1 (x, y)
#> extent : -180, 180, -60, 90 (xmin, xmax, ymin, ymax)
#> coord. ref. : lon/lat WGS 84
#> source : example_climate_v1.3.0.nc:BIO1
#> varname : bio01 (annual mean temperature)
#> names : bio01_-15000, bio01_-10000, bio01_-5000, bio01_0
#> unit : degrees Celsius, degrees Celsius, degrees Celsius, degrees Celsius
#> time (years): -13050 to 1950
Note that terra stores dates in years as AD, not BP. You can inspect the times in years BP with:
time_bp(climate_region)
#> [1] -15000 -10000 -5000 0
We can then plot the time series of a given variable (we relabel the plots to use years bp):
terra::plot(climate_region$bio01, main = time_bp(climate_


Configuring Explorer for RasMol
Configuring your browser for RasMol
Internet Explorer
There are a number of problems running rasmol scripts through internet explorer. Our first suggestion is to go and use Netscape. However if you want to persist these are our hints.
Internet explorer is much more closely related to the windows operating system than Netscape. This means that there are more combinations to deal with. These instructions are based on Windows 2000 Pro and IE 5.5 and 6.0. They may give you ideas of what to try on other combinations, but copying them unthinkingly may not work. The first step is to set up the following two files. You might want to save them in the same directory as your raswin.exe (in our case c:\program files\rasmol\raswin.exe, but it does not matter as long as you know where they are. If you use several machines and have a folder that is loaded up whichever machine you are on it might be better to put them there.
In windows
rasstart.bat
"c:\Program Files\rasmol\raswin.exe" -pdb "%~1"
rasscriptstart.bat
"c:\Program Files\rasmol\raswin.exe" -script "%~1"
Registering file types
You then have to tell the browser how to handle files of the relevant types. If you click on the 'My Computer' icon on your desktop, you start up Windows Explorer. Go to 'Tools' 'Folder options' and select the 'File Types' tag. Depending on the access permissions that you have on the system the New and Change boxes may or may not be clickable. If they are not clickable you cannot carry on, you will need to involve your system manager or use the hints below. If there are look to see if there is a PDB file extension already. If there is not do the following
 1. Click New
 2. Enter File type PDB
 3. Click Advanced to get 'Edit File Type'
 4. Click New to get 'New action'
 5. Enter 'open' in action
 6. In the 'application' box, browse to your raswin executable but before entering OK add %1 to the line so that it reads "C:\program files\rasmol\raswin.exe" %1
 7. Hit OK until you have closed all the dialogue windows.
You have now defined the .PDB extension. You should repeat it for .RAS and .PL files which are the extension on rasmol scripts except the application box should read "C:\program files\rasmol\raswin.exe" -script "%1"
If you have a PDB, PL or RAS file saved to disk you should now be able to click on them and they open up.
Trouble shooting or no permission to change file extensions
You may have notices the Change box on the 'Folder options' dialogue. The files will not work if you just put raswin there, it will start but not open the files. You can instead put rasscript.bat for PL and RAS files or rasstart.bat for PDB files. These should work here. If you click on an individual file and go to properties, it will tell you the type of file and what program opens with. Even if you do not have permission to change file extensions you can change the program here. In this case you should use rasstart or rasscript not raswin -if they do not come up on the menu browse to them using 'Other' button.
Further Problem
Internet explorer saves files to a place with a space in it. It is important to use a recent version of raswin (eg 2.7.4.2) which will deal with this.
If you are still stuck
The ultimate fall back is to save the files to disk (to a folder without a space in the name) and start rasmol and use 'File' 'open' to open the PDB file or type 'script' filename to start a script.

What is the National Animal of Ireland?
The mountain hare, the national mammal of the country of the Ireland.
A national animal, just like any other state symbol, must have symbolic meaning in order to represent a country. To this Ireland is no exception. However, because the country was not partitioned until 1922 many national symbols represent the period of Ireland before the division.
The National Bird
In the year 1990, the Irish Wildlife conservancy declared the northern lapwing bird as the national bird of the Republic of Ireland, while the Eurasian oystercatcher acts as the national bird for Northern Ireland. This decision was made in 1961 albeit unofficially. Several birds have been put forward as suitable candidates for the national bird position. These birds have included species such as the peregrine falcon, Eurasian curlew, Bohemian waxwing, common swift, and northern pintail.
The national fish of Ireland is the Nothern pike. Fresh water fish have been described as Ireland's national fish. They are also called coarse fish. This category includes the likes of bream perch and carp.
Dog Breed
The national dog breed for the Republic of Ireland is the Irish Wolfhound though some people contest the idea, proposing the Kerry Blue Terrier as the substitute.
The national land animal is not very clear although the Irish Hare has been treated as the national animal. It can be noted that the hare was not the original idea for a national animal. Initially the Irish elk is what was defined as the national animal, an iconic mammal that was found in the whole of Northern Europe. Since this mammal no longer exists, the next possible contender for the spot was the red deer. This was not well received as its origin was also not very clear. Some people still consider the red deer as the national animal. It has faced extinction as its population reduced to such a point that a conservation project was created just to protect the species.
The mountain hare was agreed on as the national animal. This animal is unique to Ireland and not found in any other place. Despite their position of importance this sub species is sadly on a slow decline. The number of mountain hares has been reducing gradually to the concern of many in Ireland who love the animal. According to a survey that was carried out in farms around mountainous areas, the animal might need to be protected from consumption.

I'm studying about the design of controller in digital control systems. Right now I see the method in which I design my controller in the s domain and then convert it to the z domain.
However, in order to achieve specifications I must choose a suitable sampling period. Otherwise the transfer function in the z domain might have (for example) different poles from those I was going for.
What I do I know is that the bigger the sampling period T the greater the problem. Seeing some examples they choose a T which is 0.1-0.5 times the smallest time constant of the transfer function. In other examples of second order systems T is chosen so $$T<2π/(40ω_d)$$ where ω_d is the natural frequency.
So how should I choose my sampling period?

Why is standardisation important?
- A lack of standardisation impedes the development of the market. Using multiple standards means devices cannot communicate. Standardisation is important for the industry to be truly efficient and integrated.
- However it is important that the standard is allowed to develop over time. Technology in this sector is moving on and any standard needs to be flexible enough to move with technological changes.
- This community is dedicated to promoting a progressive standard. As technology develops, the WAVE2M standard will be allowed to develop and improve.

Cool Electronic Toy for Kids: Symphony in B. by B. Toys
Symphony in B.
Last week, Toca Band was selected as Screen Play's app of the week for the sheer fun of mixing and matching musical melodies and rhythms. If you'd like to give your child a similar musical experience in the real world (as opposed to the virtual one), Symphony in B. by B. Toys is a gem of a toy that kids of all ages will enjoy.
B. Toys is known for its innovative, colorful and highly interactive toys. I featured another one of its popular products last year – the Alphaberry. Symphony in B. is another hit and combines so many different learning experiences into one. Fashioned as an orchestra pit of sorts, the toy lets its users explore different sounds, lights and musical combinations.
Similar to the Toca Band app where players and instruments can be moved around to hear different effects, the 13 instruments that come with this toy do the same thing. Kids can place up to six instruments in the center and the sensors at the bottom immediately play whatever sounds that particular instrument makes. With 15 different songs to choose from and 13 instruments, the different combinations are limitless.
Buttons on the toy also designate which instruments are classified as percussion, woodwinds, brass, keyboard and strings. Maybe a concept a tad advanced for its youngest users, but great tidbits to know as kids learn more about instruments. In addition to forming an appreciation for music, the Symphony in B. also helps kids practice learning about colors and shapes when putting the instruments back into place.
B. Toys has created another masterpiece with the Symphony in B. Your little musical genius will love it.
To see how the toy works, check out this video demonstration.
Symphony in B. is available from for $49.99.

What is a self-closing script element?
A self-closing script element is a piece of code that is written to execute a script without requiring any additional coding. It is written in the same syntax as a regular script element, but the opening and closing brackets are omitted. This means that the code can be written in a single line, which is why it is often referred to as a "one-liner".
For example, the following code is a self-closing script element that prints the phrase "Hello World" to the console:
As you can see, this code does not require any additional coding to make it work. All you need to do is copy and paste the code into your script and it will run as expected.

Kingdom of Earth is the 'sovereign world state'declared over the planet earth ("the World")
The origin of Kingdom Of Earth
Kingdom of Earth is the 'sovereign world state'declared over the planet earth ("the World"). The Kingdom was declared in London on 2nd November 2009 by Prince Ali Afolabi of Olubonku Royal House of Iree, a community within Nigeria. Prince Afolabi (now King Afolabi) was divinely ordained the "King of Earth" and commanded to proclaim the Kingdom of Earth in 1994.
However, he hesitated in doing so for 15 years for fear that the world may not be ready for a world state with an absolute Monarch when the citizens of the nation states around the world are clamouring for democracy. Prior to his divine commission, King Afolabi was a successful businessman but his initial refusal to obey the divine call costs him his business and family. His refusal also brings him so many unexplainable troubles.
In the midst of one of his troubles in 2009, he was divinely visited once more and commanded to assume his position as King of Earth and proclaim the Kingdom of Earth or he will die. With no other option he reluctantly assumed his position as the King of Earth and proclaimed the Kingdom of Earth. He informed the world leaders about his divine mission and unsurprisingly, most of the people around him and the world leaders believe that he was suffering from mental illness as they cannot comprehend such a divine mission. The mission of the King of Earth is to serve people in the world wherever they live, to promote world peace, global economic prosperity, religious tolerance and freedom of movement.

When the area to be irrigated has a high slope gradient in the manifold line direction, an option is to use a tapered pipeline to economize on pipe costs and to keep the pressure head variations within desired limits. The purpose of this paper is to develop a linear programming model to design a microirrigation system with tapered manifold lines in the downhill condition, minimizing the equivalent annual cost of the hydraulic network and the energy annual cost, and assuring that the maximum variation in the pressure head previously established will be observed. The input data are: irrigation system lay-out, cost of all hydraulic network components and energy cost. The output are: equivalent annual cost, pipeline diameter in each line of the system, pressure head in each node, and total operating pressure head. To illustrate its capability, the model is applied in a citrus orchard in Sao Paulo State, Brazil. The model proved to be efficient in the design of the irrigation system in terms of the emission uniformity desired. The annual pumping cost must be considered in the microirrigation system design because it yields a lower total annual cost when compared with the same alternative without that cost.


Newman-Conway Sequence
Difficulty Level Easy
Frequently asked in Amazon Honeywell
Dynamic Programming Math Sequence
Problem Statement
The problem "Newman-Conway Sequence" states that you are given an input integer "n". Then you need to print first nth element of the Newman-Conway Sequence.
n = 6
n = 10
Since the output elements represent the sixth and tenth element of the Newman-Conway Sequence. The output is absolutely correct.
Approach to find Newman-Conway Sequence
The Newman-Conway Sequence is a sequence whose each term satisfies the following recurrence relation.
P(1) = P(2) = 1
Newman-Conway Sequence
Now we need to print the nth number from the sequence. There can be two methods because each element of the sequence is dependent on the previously generated elements. So, one of the ways is to use recursion but this method is inefficient. Because we will be solving for each element many times, as we keep on calculating for higher terms in the series. Thus we need to perform a much more number of computations. So to resolve this problem of re-computation. We may use Dynamic Programming which can highly improve the efficiency of the algorithm. Currently, the recursive algorithm needs exponential time complexity. We can reduce it to a linear solution because there is only a single state.
So, in the dynamic programming solution. We will create an array that will store the elements which come before the nth element. That is all the elements from the first element to (n-1)th element. Then using these precomputed we will find our nth element. Since we have all the numbers which need to precomputed before nth number. We can easily use these values instead of calculating the required elements again and again. This technique is used to reduce the time complexity of

Complexity Analysis
Time Complexity
O(N), because we simply ran a single loop to find the nth element of the sequence. Thus the time complexity is linear.
Space Complexity
O(N), since we have used a DP array to store the intermediate results which were required for the computation of nth element. The space complexity is also linear.

Finnmark County, NorwayEdit This Page
From FamilySearch Wiki
Norway > Finnmark County
Finnmark is a county in the extreme northeast of Norway. By land it borders Troms county to the west, Finland (Lapland) to the south and Russia (Murmansk Oblast) to the east, and by water, the Norwegian Sea (Atlantic Ocean) to the northwest, and the Barents Sea (Arctic Ocean) to the north and northeast.
The county was formerly known as Finmarkens amt or Vardøhus amt, and since 2002, has had two official names: Finnmark (Norwegian) and Finnmárku (Sami language). It is part of the Sápmi region, which spans four countries, as well as the Barents Region, and is the largest and least populated county of Norway.
Situated at the Northernmost part of continental Europe, where Norway swings eastward, Finnmark has always been an area where east meets west, in culture as well as in nature and geography.

Define the action of $S_n$ on $\mathbb{R}^n$:
take any $x\in S_n$, consider the mapping $x: \mathbb{R}^n\to\mathbb{R}^n$, $e_1, e_2...e_n$ are the standard basis of $\mathbb{R}^n$, $x(e_k)=e_{x(k)}$, clearly $x$ is a linear transformation.
How to show that if $x\in S_n$ is a reflection to some vector then $x$ is a transposition?
I can only show that transpositions are reflections, how to show that there are no more?

2 Answers 2
If $x \in S_n$ defines a reflection of $\mathbb R^n$, then $x$ has order 2, thus it is a product of transpositions. If one of these transpositions is $(1\;2)$ then $e_1$ is mapped to $e_2$ and vice versa. There is only one reflection with this property, namely the reflection at the hyperplane orthogonal to $e_1-e_2$. This reflection leaves all the $e_i$ ($i \neq 1,2$) unchanged, so $x$ is the transposition $(1\;2)$.

This is a great explanation. OP should accept this :) – Enzo Apr 24 '13 at 5:19
If $p$ is a permutation whose disjoint cycle decomposition is $c_1c_2\cdots c_r$ (including cycles of length $1$), then the multiplicity of $1$ as an eigenvalue of the map induced by $p$ is precisely $r$. It follows that $p$ is a reflection iff there is exactly one cycle of length $2$ and all the rest are of length $1$; of course, this happens exactly when $p$ is a transposition.
Of course, we have to check my initial claim on the multiplicity of $1$.
Consider the matrix $M$ of the map induced by $p$. It is easy to see that, up to permuting the basis, $M$ is in fact a diagonal block matrix, with one block corresponding to each of the cycles $c_i$. The multiplicity of $1$ as an eigenvalue is therefore the sum of the multiplicities of $1$ as eigenvalues of each of the permutation matrices corresponding to the $c_i$. We are thus reduced to showing that if $p$ is the cycle $(1,2,3\dots,n)$, then $1$ is a simple eigenvalue. But this is immediate: the characteristic polynomial, which coincides with the minimal one, is $x^n-1$.

Thermodynamic - water/ice piston help!
An inventor proposes to make a heat engine using water/ice as the working substance inside a cylindrical piston and taking advantage of the fact that water expands as it freezes and can therefore lift a piston supporting some mass m. The engine process consists of four steps as shown in the schematic below.
(i) Load: The weight to be lifted is placed on top of a piston over a cylinder of water held at a temperature of 1oC. The piston sits at height hw.
(ii) Lift: The system is then placed in thermal contact with a low temperature reservoir at −1oC until the water freezes into ice, lifting the weight to a height hi.
(iii) Unload: The weight is then removed at height hi while the ice remains frozen.
(iv) Reset: The ice is melted by putting it back in contact with the high-temperature reservoir at 1oC, returning the piston hw. Another mass is added to the piston and the cycle is ready to be repeated.
The inventor is pleased with this device because it can seemingly perform an unlimited amount of work (by lifting an unlimited mass m) while absorbing only a finite amount of heat each cycle.
Assuming that the piston has a cross-sectional area of 10 cm2 and contains 50 cm3 of liquid H2O (i.e. hw = 5 cm), calculate:
(i) The work done by the piston in raising a mass of 10 g.
(ii) The mass required to stop the engine working (i.e., reduce the freezing point of the water to −1oC).

The need for fast and accurate performance testing of solar collectors is increasing. This paper describes a new technique for performance testing which is based on non-linear continuous time models of the heat dynamics of the collector. It is shown that all important performance parameters can be accurately estimated with measurements from a single day. The estimated parameters are compared with results from standardized test methods (Fischer et al., 2004). Modelling the dynamics of the collector is carried out using stochastic differential equations, which is a well proven efficient method to obtain accurate estimates of parameters in physical models. The applied method is described by Kristensen et al. (2004) and implemented in the software CTSM1. Examples of successful applications of the method includes modelling the of the heat dynamics of integrated photo-voltaic modules (Friling et al., 2009) and modelling of the heat dynamics of buildings (Madsen and Holst, 1995). Measurements obtained at a test site in Denmark during the spring 2010 are used for the modelling. The tested collector is a single glazed large area flat plate collector with selective absorber and Teflon anti convection layer. The test rig is described in Fan et al. (2009). The modelling technique provides uncertainty estimates such as confidence intervals for the parameters, and furthermore enables statistical validation of the results. Such tests can also facilitate procedures for selecting the best model to use, which is a very non-trivial task.

The difference is so small that people don't give too much care about which should be used. Also the use of each word is defined by been formal or informal (in some places)
- Acordar -> Agreement between two or more parts.
- Acordar -> Used instead of recordar / "no me puedo acordar donde puse
There is also a new variant to these two used in some places
- Re-acordar -> Start to remember something again.
If used on the sense of "remembering" like in ¿oye, te acuerdas de esa película?, The question implies that both persons where together watching the movie, while ¿oye, recuerdas esa película? the person could had seen the movie at a different time (not with the person that ask the question). Although This is not a rule, and may not be correct in all countries.
Without been an expert I will say that personally, I will use one instead on the other depending on the case (formal or informal).
To answer your question correctly I will say that the use depends quite a lot on the region/country and unfortunately there in no rule that can be successfully applied to all countries (since the use of the word or meaning given in some countries may differ from the sense or meaning of the word given by others in other countries).

In order to make a clap switch, we have to combine the touch sensor(monostable mode of 555 and the transistorized dark sensor circuits. Whenever there is loud sound produced near the electret condenser mic, pin 2 of 555 gets triggered and it switches on the LED D1. The LED remains on for a definite time determined by R1 and C1. We can adjust the sensitivity of the circuit using a variable resistor in place of fixed resistor R5. You can check the circuit with 1K or 10K.

I have observed that the same amount of sugar tastes differently in hot and in cold coffee. If I drink hot coffee, I feel I can add more and more sugar, without it tasting too sweet. However, cold coffee tastes overly sweet with only small amounts of sugar.
Why does this happen? Why does sugar taste differently sweet in cold and hot coffee?
share|improve this question
The question is a little ambiguous, but sugar dissolves more readily in hot liquid than in cold liquid, which might explain the effect you describe. – user5561 Mar 16 '12 at 16:17

Its possible that when you drink a hot liquid, you swish it around your mouth a lot less than when you drink a cold liquid, and thus fewer of the taste buds on your tongue are exposed to it. This wouldn't be surprising: it's hot after all.
Another possibility is that if you're starting with hot coffee, and adding sugar to it, that the sugar isn't fully dissolved when you drink it hot (it takes time, especially if you don't stir it much), but has dissolved by the time the coffee cools. With more dissolved sugar, it is sweeter.
share|improve this answer
This research paper suggests that, in general, pH, temperature, and ions don't generally significantly affect our perception of sweetness intensity. Since temperature and acidity are the two major differences between iced and hot coffee (depending on preparation), this more or less rules out the possibility of a chemical difference.
"The main finding from this three-part study was that temperature, pH, and ions had little effect on the perceived sweetness intensity of the sweeteners studied. Even when significant differences were found in the temperature study, the effects were very small."
This, to me, suggests it's either due to larger "sips" of cold coffee and more of an opportunity to taste the sweetness or because sugars dissolve less readily in the cold coffee and it's easier to perceive the sweetness when it's not in a solution.
share|improve this answer
I suggest the change is in the coffee rather than the sugar. Coffee is more aromatic when hot. When you put the same amount of sugar in a hot and cold cup of coffee, the sweetness will dominate more in the cold coffee where there the coffee taste/aroma is less pronounced.
share|improve this answer
Actually, it has nothing to do with the solubility of the sugar. The reason is that fructose (in an aqueous solution) has two different cyclic forms. The Beta-fructopyronose form (6 membered ring form) is much sweeter than the furanose (5 membered ring) analog. At lower r temperatures the equilibrium shifts and more of the pyranose-ring fructose is present (converted from alpha and beta fructofuranose) thus increasing the perception of sweetness.

Cold coffee tastes less bitter than hot coffee. When I was a kid I worked in a bakery. The last pot of coffee was always left for the first bakers, who came in at 3 AM. By the time I got there at 5 AMthe coffee was at least 12 hours old and on a burner for at least a couple of hours.
I found that if you put some of the coffee over ice it tasted OK. My favorite coffee drink today is ice with a couple of shots of espresso. No sugar needed.

In words:
The probability that the Coin is the first Coin, given that we know heads came up 4 times... Is equal to the probability that heads came up 4 times given we know it's the first coin, times the probability that the coin is the first coin. All divided by the probability that heads comes up 4 times (ignoring which of the three Coins is chosen). The binomial coefficients cancel out as well as all denominators when expanding 1/2 to 2/4. This results in
\frac{3}{3 + 32 + 81}=\frac{3}{116}
In the same way we find:
P(C_2|X=4)=\frac{32}{3 + 32 + 81}=\frac{32}{116}
and
P(C_3|X=4)=\frac{81}{3 + 32 + 81}=\frac{81}{116}.
This shows us that after examining the outcome of the five throws, it is most likely we did choose coin number 3.
Actually for a given result the denominator does not matter, only the relative Probabilities p(C_i) = P(C_i|X=4)/P(X=4) When the result is 3 times heads the Probabilities change in favor of Coin 2 and further as the following table shows:

Distributions[edit]
How are the results of the latest SAT test? What is the average height of females under 21 in Zambia? How does beer consumption among college students at engineering college compare to college students in liberal arts colleges?
To answer these questions, we would collect data and put them in a form that is easy to summarize, visualize, and discuss. Loosely speaking, the collection and aggregation of data result in a distribution. Distributions are most often in the form of a histogram or a table. That way, we can "see" the data immediately and begin our scientific inquiry.
For example, if we want to know more about students' latest performance on the SAT, we would collect SAT scores from ETS, compile them in a way that is pertinent to us, and then form a distribution of these scores. The result may be a data table or it may be a plot. Regardless, once we "see" the data, we can begin asking more interesting research questions about our data.
The distributions we create often parallel distributions that are mathematically generated. For example, if we obtain the heights of all high school students and plot this data, the graph may resemble a normal distribution, which is generated mathematically. Then, instead of painstakingly collecting heights of all high school students, we could simply use a normal distribution to approximate the heights without sacrificing too much accuracy.
In the study of statistics, we focus on mathematical distributions for the sake of simplicity and relevance to the real-world. Understanding these distributions will enable us to visualize the data easier and build models quicker. However, they cannot and do not replace the work of manual data collection and generating the actual data distribution.
What percentage lie within a certain range? Distributions show what percentage of the data lies within a certain range. So, given a distribution, and a set of values, we can determine the probability that the data will lie within a certain range.
The same data may lead to different conclusions if it is interposed on different distributions. So, it is vital in all statistical analysis for data to be put onto the correct distribution.

Discrete Distributions[edit]
'Discrete' data are data that assume certain discrete and quantized values. For example, true-false answers are discrete, because there are only two possible choices. Valve settings such as 'high/medium/low' can be considered as discrete values. As a general rule, if data can be counted in a practical manner, then they can be considered to be discrete.
To demonstrate this, let us consider the population of the world. It is a discrete number because the number of civilians is theoretically countable. But since this is not practicable, statisticians often treat this data as continuous. That is, we think of population as within a range of numbers rather than a single point.
For the curious, the world population is 6,533,596,139 as of August 9, 2006. Please note that statisticians did not arrive at this figure by counting individual residents. They used much smaller samples of the population to estimate the whole. Going back to Chapter 1, this is a great reason to learn statistics - we need only a smaller sample of data to make intelligent descriptions of the entire population!
Discrete distributions result from plotting the frequency distribution of data which is discrete in nature.
General Properties[edit]
Cumulative Distribution Function[edit]
A discrete random variable has a cumulative distribution function that describes the probability that the random variable is below the point. The cumulative distribution must increase towards

Scientists at Australia's University of Newcastle have successfully tinkered with 3D-printed solar cells for years. Now they want to prove that these solar panels are also efficient – by sending a Tesla vehicle on a 15,000-kilometer journey.
The researchers are currently testing printed solar panels that they plan to use to power a Tesla on a 9382 miles journey this September. As part of the "Charge Around Australia" project, a Tesla vehicle will be on the road with a total of 18 printed plastic solar cells to charge the vehicle while it is stationary.
The printed solar cells can be rolled up for driving, and when unrolled, they are each 18 meters long.
Paul Dastoor, the inventor of the printed solar panels, tells Reuters news agency that the Newcastle University team wanted to test the endurance of the panels and their potential performance for other applications.
Less than $10 per 10.7 square foot
"In fact, this is an ideal test bed to give us insight into how we could use and power the technology in other remote locations, such as in space," Dastoor told Reuters.
The printed solar cells are made of lightweight, laminated PET plastic that can be produced at the cost of less than $10 per 10.7 square foot. The cells are printed using a commercial printer originally used to print wine labels.
Dastoor hopes that using the panels as a car's power source could get Australians thinking more about electric vehicles and help ease their range anxiety. "[The] community is looking for these kinds of answers to the problems they face every day around climate change," the solar printing inventor said.
During the 84-day journey, during which the E-car will travel the entire Australian coastline, the project team plans to visit about 70 schools to give students a glimpse of what the future might have in store.


Problems understanding TTrees and TFiles
Hi,
I'm very new to ROOT, and I am having a huge amount of trouble trying to understand TTrees, TFiles, Events and their relationship to one another.
From the examples, I cannot see how you attach a TTree to a specific file. The examples show how to create a file, then how to create a tree, but the tree never references the file. I cannot work out how to get a particular tree to be stored in a certain file.
The code below is what I am trying to get working. I am reading in large amounts of text from a file, creating my event, and then want to store the event in a .ROOT file (the name of the file is dependant on certain attributes of the record I have read in from the text file).
So to summarise, I have already created my event (pEvent), and just want to store it in a tree in a certain file. The following throws an exeption no matter what I try.
// Create a ROOT File
TFile hfile(strRootFile,"RECREATE","Data");
// Create a ROOT Tree
TTree tree(strRootTree,"A Root tree");
TBranch *eventBranch = tree.GetBranch( strRootTree );
if( eventBranch == NULL )
{
eventBranch = tree.Branch( strRootClass, strRootClass, pEvent, 32000, 99);
}
tree.Fill();
Any help is very welcome.
All the best,
Tony.
if pEvent is a pointer to say MyEvent, you should pass the address of the pointer and not the value of the pointer, ie replace
TBranch *eventBranch = tree.GetBranch( strRootTree ); if( eventBranch == NULL ) { eventBranch = tree.Branch( strRootClass, strRootClass, pEvent, 32000, 99); } by

Hi again,
Can you advise me a little more? I have a function below, I am not certain it is what I want it to do.
Basically I have an event (pEvent) and want to put it into a certain file on a certain branch. I have the file name and branch name, but I cannot figure out from the ROOT help/documentation how to make sure my event gets stored in the correct place.
I am totally lost at the moment.
All the best and thanks in advance for any assistance.

//first get the filename needed, and then see if we have the file open.

TFile *hfile = NULL;
TBranch *eventBranch = NULL;
int nFile = m_FileNames.Find(strRootFile);
if ( nFile != -1 )
{
 //get the file pointer
 hfile = m_FilePtrs.GetAt(nFile);
 tree = m_TreePtrs.GetAt(nFile);
 eventBranch = m_BranchPtrs.GetAt(nFile);
}
else
{
 //first check to see if the file we want exists.
 hfile = new TFile(strRootFile,"UPDATE","Data");
 if ( hfile == NULL )
 {
 // Create a ROOT File

 m_FilePtrs.Add(hfile);
 m_TreePtrs.Add(tree);
 m_BranchPtrs.Add(eventBranch);
}
tree->Fill();
}[/code]
When you pass the pointer to your object (&pEvent), the branch retains this address (as it is used by the branch to (potentially) pass information back to you).
However the address you pass to the branch is transient (as it is on the stack).
So you need to correct your code in the following way:[code]void CROOTFileManager::Add(CMyEvent *pEvent)
{
//first get the filename needed, and then see if we have the file open.
//if open, append,
//if not open, create and add
CStdString strRootFile = pEvent->GetROOTFileAsString();
CStdString strRootTree = pEvent->GetROOTTreeAsString();
CStdString strRootClass = pEvent->GetROOTClassAsString();
TTree *tree = NULL;
TFile *hfile = NULL;
TBranch *eventBranch = NULL;
int nFile = m_FileNames.Find(strRootFile);
if ( nFile != -1 )
{
//get the file pointer
hfile = m_FilePtrs.GetAt(nFile);
tree = m_TreePtrs.GetAt(nFile);
eventBranch = m_BranchPtrs.GetAt(nFile);
}
else
{
//first check to see if the file we want exists.
hfile = new TFile(strRootFile,"UPDATE","Data");
if ( hfile == NULL )
{
// Create a ROOT File
hfile = new TFile(strRootFile,"RECREATE","Data");
 // Create a ROOT Tree
 tree = new TTree(strRootTree,strRootClass);
 }
 else
 {
 // Create a ROOT Tree
 tree = (TTree*)hfile->Get(strRootTree);
 if ( tree == NULL )
 {
 // Create a ROOT Tree
 tree = new TTree(strRootTree,"");
 }
 }
 eventBranch = tree->GetBranch( strRootClass );
 if( eventBranch == NULL )
 {
 eventBranch = tree->Branch( strRootClass, strRootClass, &pEvent, 32000, 99);
 }
 m_FileNames.Add(strRootFile);
 m_FilePtrs.Add(hfile);
 m_TreePtrs.Add(tree);
 m_BranchPtrs.Add(eventBranch);
}
tree->SetBranchAddress(strRootClass, &pEvent); // Always set the address to the 'current' location[Code Added]
tree->Fill();
tree->ResetBranchAddresses(); // Forget stack addresses }
Cheers,
Philippe.

Developing urban metabolism indicators for a better usage in metropolitan area municipalities
The urban metabolism approach has been proposed for more than half a century. Its applications, especially the indicator analysis, are applied in many domains. By the indicator analysis of an area's metabolism, development strategies and urban design outcomes can be proposed from the perspectives of resource consumption and waste production. Since a large number of activities of metropolitan areas' municipalities have started to integrate urban metabolism issues with urban development, there seems to be a substantial gap in the urban metabolism indicator study of metropolitan areas and corresponding local public administrations. This study is aimed at developing urban metabolism indicator framework, to support the urban design procedure of metropolitan area. To put the proposed indicators into practice, a set of urban metabolism indicators is proposed to be adopted in Amsterdam Metropolitan Areas. The selection process is conducted by using the Delphi method. In doing so, 2-round questionnaire is responded by qualified experts to select the most relevant and practicable urban metabolism indicators. Then, these selected indicators are generated and grouped into different categories. By organising the Peri-Urban Living Lab (PULL) Workshop Amsterdam Metropolitan Area, the potential usage of these indicators will be evaluated. In the meantime, PULL stakeholders will categorise and prioritise these indicators from different fields. Afterwards, the urban metabolism indicator framework will be established based on the perspectives from urban metabolism related stakeholders. This exploration contributes to the field of practical application of urban metabolism indicators in municipalities of metropolitan areas.

Media has emerged as an essential source of communicating climate research to policymakers and the public around the world. However, media in developing countries, like Pakistan, lack the capacity to translate the scientific information and linking it to everyday life due to which the issue faces negligence on a wider scale. The proposed project aims to build the capacity of journalists and media persons of Pakistan through training workshops to effectively communicate the scientific information on climate change to policymakers and other stakeholders. The training workshop will serve as a platform for the media to interact with climate scientists and empower journalists and reporters to understand the technicalities of climate science and related uncertainties. Also, the project aims to disseminate the outcomes of the APN project on extreme events to the general public and students through dedicated news articles, TV interviews and seminars with a particular focus on highlighting the role of APN in promoting regional research. These activities would eventually contribute to better communication of the country's vulnerability to climate extremes and would ultimately bring the issue to the forefront of policy priorities.

New Seedlings, New Beginnings: HOPE's First Coconut Relief Drive
Typhoon Odette swept through the nation in mid-December of 2021, devastating communities in Visayas and Mindanao, who were left without basic necessities such as food, water, and shelter.
Unbeknownst to many is the fact that agricultural lands were also wiped out by the storm. Such was the case for smallholder farmers in the province of Surigao del Norte, who rely on coconut trees as one of their main sources of income. According to the Philippine Coconut Authority, 70% of coconut trees were destroyed during the typhoon. It would take 3-5 years for the decimated trees to be restored.
A cluster of destroyed coconut trees. The coastal areas of Surigao were especially affected by the typhoon.
To aid in their process of rebuilding, HOPE reached out to local government units in Surigao to organize a relief drive that will distribute coconut seedlings to farmers who were severely affected by the disaster. By working closely with the Philippine Coconut Authority, HOPE was able to identify smallholder farmers across the communities of Surigao City, Placer, and San Francisco.
"The Surigao operation was a new experience for the agriculture team," says Bruce Arinzol, Farmer Engagement Officer. "We're used to distributing coconuts to partner farmers who want a stable source of income. However, with this operation, the need was different and overwhelming. That's why we wanted to extend help."
The relief drive happened last February 17, 2022, in all three areas simultaneously, made possible by HOPE's on-the-ground agriculture team. Each farmer got to take home an average of 50 seedlings that will help them recover the trees they had lost.
At the end of the day, 27,977 seedlings were distributed to 446 recipients. "As witnesses of the Surigaonons' resilience and hard work, we are convinced they will be able to get back on their feet again," continues Arinzol.
HOPE has been supporting farmers since 2014 with the goal of increasing income opportunities to promote sustainable livelihood. These farmers are located in Mindanao, mainly in the provinces of South Cotabato and Sarangani. HOPE commits to staying cognizant of these farmers' needs.

Details of faults affecting the use of tap switch
Release time：2020-01-07 Clicks： Click
What are the faults that affect the use of the tap switch and what are the specific details? Let's give you a detailed introduction.
As a result, some oxidation corrosion reactions will be formed. Once the shrapnel is corroded, it will lead to poor contact of the switch or failure of the switch.
Fault 1
Secondly, during the use of the tap switch, please pay attention to the daily waterproof measures of the switch. Generally, if the switch is installed and used in some humid environment,
The interface of the switch can easily lead to the invasion of water gas. Once the line contacts with water gas, the current leakage will occur,
If the human body touches it carelessly, it will cause safety problems of the circuit.
Fault two
It is forbidden to touch the button of the switch frequently and excessively. In case the cover of the button of the switch falls off, some lines inside the switch will be exposed,
If it is accidentally touched, it may cause electric shock accidents on the spot. So we should pay attention to this,
At the same time, when the switch is unnecessary, try not to over press the key switch. Every time you press the key, the switch will be worn.
Fault three
As for the common failure of keys by touching the switch, it is generally possible that the switch has been used for a long time, and its internal shrapnel has been oxidized and corroded,
Only after that, it will cause poor contact, which will cause the failure of the switch key. Therefore, to deal with this failure, it is generally necessary to disassemble the switch,
Then the oxidized part of the shrapnel for checking its switch shall be scraped clean. If the shrapnel is seriously corroded, it is only recommended to replace the switch.
Fault four
For the light touch switch, there will be some delay of key sensing, which is also possible that there are too many dust and sundries adsorbed inside the switch,
So as to cover the conductive contact of the switch wiring, thus blocking the connection of the circuit, so the post will cause the problem of the inductive delay of the switch.
Therefore, after using the switch for a period of time, it is necessary to carry out the safety inspection of the switch. If it is found that there is too much dust and sundries adsorbed,
Be sure to deal with it in time to avoid affecting the performance of the switch. Thirty-eight point two zero

Warren, Sanders want climate change considered in selection of homeland security adviser
Sens. Elizabeth Warren (D-Mass.) and Bernie Sanders (I-Vt.) are calling on the Trump administration to consider the effects of climate change when selecting President Trump's next homeland security adviser.
In a letter to Trump, the two senators urge the president to select an individual who "takes seriously" severe weather patterns and storms caused by a changing climate.
"The Homeland Security Advisor regularly attends meetings of the National Security Council and is responsible for overseeing the Administration's response to natural disasters, including hurricanes," reads a statement from Warren's office.
"[Tom] Bossert, who served as Homeland Security Advisor since January 2017 until his resignation last month, had refused to acknowledge the overwhelming scientific consensus that human-induced climate change contributes to severe weather events."
Bossert resigned in April, after John Bolton joined the White House as national security adviser and sought to shake up the team. A replacement for the homeland security adviser has not yet been announced.
"Without a dedicated federal effort to reduce the quantity of greenhouse gasses that human activity releases into the atmosphere, climate change will continue to worsen and cause increasingly severe weather events, including hurricanes," the two senators wrote in the letter. "Climate change is having and will have a tangible and harmful impact on our national security and disaster readiness."
The Trump administration has moved to strip fighting climate change from government websites and policies. The president announced last year that the U.S. would exit the Paris climate accord, a global agreement aimed at reducing greenhouse gas emissions.

Start of construction of heat pipeline between the port of Rotterdam and The Hague
Gasunie and the Ministry of Economic Affairs and Climate Policy have taken the final investment decision for the construction of a heat pipeline from the port of Rotterdam to The Hague.
The construction of the underground pipeline will make residual heat from companies in the port available to up to 120,000 homes and other buildings in the region. The construction of the WarmtelinQ pipeline is expected to be completed in 2025.
Using residual heat
At present, most industrial heat is released by for instance oil refining and petrochemical processes. By heating homes, business premises and greenhouses with this residual heat, it will be put to good use and much less gas will be needed. Initially, the heat available in the Botlek and Pernis will be used. In the long term, the possibilities in Europoort and Maasvlakte will also be examined.
Greening of the heat
In the coming years, the industry will continue to electrify. The green energy from wind farms will then be used for the processes in hydrogen plants as well as in the existing industry. Even in this situation, residual heat will continue to be released. In the production of, for example, green hydrogen by means of electrolysis, approximately 30% of the primary energy is released as residual heat. These sustainable residual heat sources ensure that the heat is increasingly 'green'.

Do Drywall Screws Rust?
Screws are screws right? Believe it or not there are many different types of screws that are used for certain projects or situations. This means that they are made from different materials and configured differently in order to get their specific job they are designed for done in their own special way.
In this article we will be specifically talking about the drywall screw. Just like the name gives away it is typically used to hangup sheets of dry wall to wall studs or ceiling joists.. I know, mind blowing stuff right? So one question we may ask ourselves related to drywall screw is… do drywall screws rust? Even though the black phosphate outer coating will help prevent rusting of a drywall screw, these screws will eventually rust. Since after awhile drywall screws will rust, they are typically only used for indoor projects. If used outdoors it can cause them to rust since they would be exposed to the elements.
If you want to find the best Drywall Screws, click here.
What is a Drywall Screw?
A drywall screw are the standard screw used to secure sheets of drywall. Many people will also use drywall screws for other projects because they are inexpensive and the heads on these screws are flat, meaning they will keep from sinking into the wood. This means there is less of a chance of splitting the wood. You need to be careful using a drywall screw for non drywall projects because they are very brittle and can snap easily.
What Causes Rust?
Rust is a natural process where the iron in metals comes into contact with oxygen and water. This then causes it to corrode and deteriorate. Since oxygen and iron have opposite charges they are attracted to each other. So when they combine it causes oxidation and the reaction then creates rust.
Rusting causes issues because it looks gross and makes the metals become weak by causing decaying. This causes major problems because you expect metal to be a strong and durable metal but if rust is occurring that once strong object could become weak and nimble and cause serious problems with the functionality.
What To Do If Your Screw Rusts
If you have a screw that is deeply rusted it is important to fix this asap. If left you never know when it will snap and whatever it was holding up could crash and fall. The first thing we want to do is remove the rusted nail.
Steps to remove a rusted screw:
 1. Apply a product such as WD-40 that will help dissolve the corrosion on and around the screw. Things such as hydrogen peroxide, lemon juice, or cola can also be used.
 2. Gently tap the head of the screw with a hammer. This will cause vibrations which will allow the solution to work its way through the threads of the screw.
 3. Try to unscrew to remove the screw. If it's still stuck then try again.
 4. Clean the area where the screw was.
 5. Replace with a new screw.
Always keep an eye out for rusted screws in the home. It is vital to always replace them if they are found. We do not want to wait until it is too far gone.
The Make of a Drywall Screw
Drywall screws are inexpensive and can be bought in huge tubs because for any drywall project you are going to need a plethora of screws to get the job done. So what makes a drywall screw different than other types of screws?
The drywall screw is a threaded screw from the head to the bottom. It is coated in zinc or phosphate. The phosphate coating, which gives it its black color, is what makes it more rust resistant. This doesn't mean its rust proof though and is still not recommended for using on any outdoor projects.
Sizes Drywall Screws
Drywall screws come in many different sizes. They can range from 1-8 inches long because building materials range in thickness. Materials would range from metal sheets to wood beams.
Today's typical home will consist of 1/2 inch thick drywall, but the thickness can range from home to home. It is important to know the thickness of the drywall so you can choose the right size of drywall screw to get the job done.
 - 1/4 inch drywall: Use 1 inch to 1 1/4 inch drywall screws
 - 1/2 inch drywall: Use 1 1/4 inch or 1 5/8 inch drywall screws
 - 5/8 inch drywall: Use 1 5/8 inch or 2 inch drywall screws
Thread Types: Coarse or Fine
Drywall screws can have one of two thread types. Each are used for a very specific reason and need to be considered before buying the right one. It is important to know what your studs are made of before picking the right thread type for your drywall screws.
 1. Coarse: Used for drywall and wood projects. Have wide threads in order to grip to the wood and pull the drywall against the studs as close as possible.
 2. Fine: Used for installing drywall into metal studs. These drywall screws work great with metal because they are self threading.
Now we know if your studs are made of wood, use coarse, if made of metal, lets go with the fine thread.
Drywall Screws vs. Wood Screws
Obviously the number one use for drywall screws is to be used for putting up sheets of drywall in the home. They can either be attached by screwing into wood or metal studs.
Some DIYers use drywall screws for building projects, which I would not recommend. Drywall screws are brittle and do not bend easily, which means at any moment they could snap, especially if used in hardwood. If they snap then it leaves the shaft in the wood with the head gone… pretty hard to remove a screw with no head. Drywall screws are hardened so Phillips slots wont strip out under high stress from power tools. Wood screws are thicker and made of a softer metal making them more snap resistant. Lets make sure we use wood screws over drywall screws when we are doing any wood working.
Wood and drywall screws also have different thread patterns. Wood screws are smooth right under the head and not threaded. This part ensures the top part of the screw slides in the wood makes it easier for the lower part of the screws threads to clamp on the wood.
Drywall screws are threaded all the way to the head. Which means when two pieces are attached together sometimes it could keep them apart unless the two pieces are clamped together in the beginning.
Final Thoughts
Dry wall screws are made for a very specific job. To hang up sheets of drywall. This means if used for this specific job you probably do not have to worry about them rusting. However, if you choose to use this screw for it not intended purpose or outside, it is highly likely the phosphate covering will deteriorate over time and the drywall screws will indeed rust.
Related Questions
What type of screws are rust resistant? Any stainless steel screw are the most rust resistant.
Will zinc screws rust? Zinc screws will rust. They are corrosion resistant but will rust if the coating deteriorates or exposed to a wet environment.
Can I use drywall screw outdoors? You should not use drywall screws outdoors. The elements of the outdoors will deteriorate the phosphate coating and cause the screw to rust quickly.

Hairy Bat Tongue
Bat tongue
Micrograph: Cally Harper
You're looking at a scanning electron microscope image of a Pallas's long-tongued bat. The hairs act as a "mop" to scoop up nectar. Cally Harper and Beth Brainerd of Duke University found out exactly how such a weird tongue works:
The researchers knew the bat tongues were covered with little hairs, so they watched what happened to those hairs as the bats reached out for food.
When the tongue is inside the bat's mouth, they found, the hairs lie flat on the tongue's surface.
"And then very close to when the tongue is maximally extended, these hairs become erect," Harper says. "And when that happens, a space is created between each of the rows of hairs on the tongue tip. And nectar is loaded onto each one of those spaces."
It's like the bat's tongue is working like a mop, Brainerd says. "Not a sponge mop, but a stringy mop."
Brainerd says it turns out that each hair has blood vessels supplying it. When the bat sticks its tongue out to feed, the muscles of the tongue contract, pushing blood into the hair and making it stand on end. "The mechanism is like an active mop that's opening up to make more space for this liquid nectar to be collected," she says.
