How long do skateboards last? When should I replace it?
How long do skateboards last is a common question among skateboarders these days. This article is for you if you'd like to know the answer and tips for maximizing your skateboard's lifespan.
While it is not an easy query to address, the typical lifetime of a skateboard is about two years. In reality, it is mostly determined by several important factors, including the skateboard's manufacturer, efficiency, use, and maintenance.
In this article, I'll go through all causes that influence the lifespan of a skateboard, as well as what you should know to enable your skateboard to last longer.

Factors impacting skateboard's life?
 - Always double-check if the wheels are properly tightened. If this isn't the case, use the skate tool to tighten or loosen the skateboard nut in the truck.
 - Be familiar with all of the stunts and tricks associated with skateboarding. If you don't know the fundamentals, don't take all of these seriously.
 - One of the most important factors is skate style. Beginners usually destroy their skateboards easily since they are unfamiliar with the sport.
 - Skating on rails and ledges would easily break down the skateboard because it impacts the skateboard more than usual.
 - Weight is a significant concern. The skateboard is more likely to break down quickly if you are overweight.
 - Many people get irritated and throw the skateboard when they are unable to ride properly. If you don't want your skateboard to crack early and quickly, never do it and try to control yourself.
 - Skateboard durability – Obviously, the higher the quality and robustness of your skateboard, the longer it will last. Skateboards with high quality often cost more money and last longer than inexpensive skateboards, so bear that in mind as well.
how long does a skateboard last
Breaking skateboards
The lifespan of a skateboard varies based on the type of rider
While I mentioned that a skateboard will last around two years, this is only true for average riders. If you want to see how long your skateboard could last, figure out if you're a Daily Rider, Amateur or Professional.
To decide how long does a skateboard last, you must first consider the three styles of skateboard riders and then define which group you belong to.
The daily skateboarder
The daily rider is a skateboarder who only rides from home to work or college, and there are many skateboarders who just ride for fun from a certain location to another location that they favor every day.
Unlike the amateur rider who frequently does stunts and rides with friends, these riders just go out with friends and do stunts on occasion. Regular users should expect skateboards to last at least two to four years, based on where they ride and how they use them.
The amateur skateboarder
The amateur rider is primarily a rider who does not ride day after day, but at least three or four days per week in skateboard-friendly places.
The skateboard of an amateur rider can last at least 6 months to 2 years, and if you maintain it well and just ride occasionally, it can last much longer.
The pro skateboarder
Pro skateboarders are riders who compete in skateboarding events, ride for hours on skateboards, and practice tricks and stunts and nearly every day in order to improve.
Skilled skateboarders damage their boards more rapidly. I know many professionals who adjust their boards monthly since they perform extreme tricks that lead their boards to break down more quickly.
They would like to pay extra for new skateboards. For example, if the manufacturers do not advance the wheels to make them more suitable for skateboarding, they would just substitute them.

How to make your skateboard last longer
Here are good tips to take care of your board so that it can last as long as possible.
Skateboards should be well-maintained.
Your skateboard, like other devices, requires your attention and should be maintained daily. If you ignore it and leave dirt to accumulate on the skateboard for a long time, the effect is irreversible, and you'll have to purchase a new board soon.
Even novice skateboard cleaners will find cleaning a board to be quite quick and easy. To prevent tearing, you should sand the skateboard's sides regularly.
Sanding the edges would keep them clean and protect them from chipping. To remove the wheels from the board's axle, use a skate tool.
Remove the wheel bearings. Brush and rinse them after soaking them.
Using grease, lubricate bearings to clean the trucks and wheels.
The wheels should be immersed in the washing liquid for a short period to soften grime and dirt. However, the rest of the skate should not be.
If it's raining, don't ride your skateboard.
Water damages not just your deck, but also your trucks, bearings, and wheels. When the deck wood gets wet, it becomes soft and quickly breaks or slits apart.
Protect the board from rain and, if it does get wet, dry it quickly with an air dryer. Do not clean the board by dipping it in water because it can cause a lot of damage to the board. To clean the deck, wipe it off with a towel.
how long should a skateboard last
Don't ride your skateboard in the rain
Don't do any stunts or tricks that aren't appropriate for your ability.
Many beginner riders underestimate the difficulty of doing stunts and tricks that are inappropriate for their skill level.
Doing tricks that are not relevant to your skill level is extremely dangerous. It increases your chances of splitting your skateboard into two pieces, especially if you are a beginner rider.
Rather than attempting stunts and tricks that are inappropriate for your skill level, begin with the fundamentals and gradually progress to a more challenging and critical level. This would make you better on the skateboard and reduce the chances of breaking the skateboard.
Riding on sand, glass and stone is not recommended.
Skateboard wheels can be ruined if you ride on sand or glass, and if the skateboard crashes to the ground when standing on rough surfaces, it will be severely damaged.
And if it doesn't crack, it would quickly lose its efficacy. and it will not last for long. So, find a flat road or a designated skate park where you can skateboard smoothly and learn all sorts of tricks.
Avoid slipping on the skateboard's tail.
Many skateboarders like sliding or stopping on the tail, which not just rubs the tail against the surface but may also smash the board after a few tries. So, don't slip on the skateboard's tail because the tail is the most fragile component of the board.
Avoid leaving the skateboard in your car
Many skateboarders make the big mistake of simply leaving skateboards in the car, assuming that keeping their skateboard in a car would be far more reliable than keeping it in a cold place.
However, if you leave your skateboard in the car, the heat will be much higher, which can affect your board, including the trigger and wheels, because these components are heat sensitive.
The issue with a car is that it absorbs the maximum amount of heat while driving in the sun, particularly if the car is black; it will damage your skateboard more seriously.
Shoes Matter
Wearing the best skate shoes can extend the life of your skateboard. When skating, never purchase or wear low-quality shoes. It can put a strain on both your legs and your skateboard. You'll likely get wounded as well if you wear the wrong shoes.
Land skateboard properly
Skateboarding depends solely on landing. If you don't know how to land properly, your skateboard would most likely break down quickly. At the very least, you must try to land on your skateboard with one foot.
Try landing on both feet after you've learned to land with one foot. Every day, practise, practise, practise. Eventually, you'll be able to land on two feet.
Store the skateboard
Many riders who purchase a skate are not even thinking where to place it. There are many skateboarding racks available on the market. They are reliable and do not take up much space.
Furthermore, you do not have to worry about anyone accidentally trampling or damaging your skate. Moisture, cold and heat are rivals of this board. As a result, streets, basement, and car are not suitable places to store it.
I hope that your concern on "how long do skateboards last" has been answered in this article. Riding a skateboard is such a great activity, plus it is inexpensive and enjoyable. The production, repair, use, and quality of a skateboard all affect its lifespan.
If skaters want their boards to last for years, they should only use them on flat and dry surfaces. And after a long trip, remember to clean and lubricate your skateboard to maintain it.
Finally, suppose you want your skateboard to last longer. In that case, I recommend that you practice the fundamentals of skateboarding, advance slowly with the tricks, and purchase the best branded skateboard possible. Best of luck!

The Iowa State University Extension explains one way to differentiate between a spruce tree and a pine tree is to look at the needles. Spruce needles grow directly from a branch individually, and pine needles grow in bunches of two, three or five. Also, the bark of a spruce tree is rough rather than smooth, which sets them apart from fir trees.Continue Reading
The needles of spruce trees are sharp, pointed and square. One reliable way to identify a spruce tree is to take a needle and roll it between two fingers. If the needle rolls easily between the fingers, it is a spruce tree. Fir tree needles are flat, are soft and don't roll easily between fingers.
Spruce needles are attached to their branches with stalk-like projections. When the tree sheds its needles, these projections remain on the tree. The color and length of needles aren't reliable indicators for identifying spruce trees because these characteristics vary.
Cones of spruce trees are long and flexible rather than rigid. The scales on spruce tree cones are thinner and less woody than those on pine trees. These cones grow to between 8 and 26 inches long, and their size varies from tree to tree.Learn more about Trees & Bushes

X SERVICE: ILL-BOR-AUTH does not work when verification and user ID contain both ampersand and dot. If only one is present, it works, if both are present, error message is generated.
Error in Verification is received
Should authenticate the user with ampersand and dot in user ID and verification
The problem here is not the combination of the characters "@" and ".". The problem is the length of the verification. In the example - _EMAIL_, the verification is too long for the encryption. Although the string is shorter than 20 characters, the encryption of this string that includes the "@" and "." is more than 20 bytes long and this is why it fails.
Instead of the example :
we tried :
which was successful as the string is short. This is system limitation which cannot be changed.

Lesson 8 (pusaq ñiqin yachay)
As we grew up, more and more complex became the language we used.
Till now in this course very little complex sentences have been used.
But also in Quecha complex sentences may be built.
In this lesson I will cover the construction: if (when) ………then,
..... in different forms.
In Quechua the basic construction depends on the following traits:
- the subjects of both parts of the complex
cause-effect relation, or concurrence in time.
The primary forms are –pti, -spa and –stin.
I. -pti is used when the subject is
different and there is a cause-effect relation. If (when) you want, I
will come back here: munaptiyki, kutimusaq. Kuti-y is
to come back and –mu gives the meaning "to here". The form –pti
is always used with a personal suffix. Kuti-mu-pti-nku ri-saq,
means: I will go when they come back here. The form with –pti
comes first in the sentence. So, there is the condition up front and the
consequence or effect of the condition behind. I earlier used as a
model sentence: utkayta rimaptiyki, mana hapiyta yachanichu,
means: When you speak fast, I cannot understand. So –pti can
also be understood as an –ing form: you "speaking" fast, et cetera.
Another example: rimaptiyku runasimita, Cuscopi runakuna
kusikunku, people in Cusco are glad when we speak Quechua, (litt.
Speak-ing-we(excl), Cusco-in men glad-self-they).
Waqa-sa-pti-n llaki-ku-rqa-ni, I became sad, when she/he was
weeping. Waqa-y means to weep and waqe is a tear. Llaki-ku-y
means to be sad. –ku, meaning self, making the verb
Wañu-pti-y, pitaq waqanqa? Who will weep when I die? Wañu-y
is to die and waqa-y is to weep. (So litt. die-ing-I, who weep-future form-he?)
II. -spa is used when the subject of both
sentences is the same. Because of that a personal suffix is optional.
One of the sentences already indicates the subject. Rimaspa(y)
runasimita kusikuni: I am glad when I speak Quechua. Or: Runasimita
yachaspa(yki), imatataq ruwanki?, what will you do (for a living)
when you know Quechua? Note that ruwanki is the present tense,
but also the future tense.
III. -stin expresses the concurrence in
time of the actions in both sentences expressed, without any
cause-effect relation. For instance: puristin takisani, I am
walking while singing. With –stin no personal suffix is used. Because
of the simultaneousness, the infix –sa, the ing form, is often used. Waqastin
mikusarqaniku, while weeping we were eating.
IV. Of these forms also exist a more complex form
explicitly expressing a condition for the cause-effect relation: In case
you want, I will do (it): qam munapti-yki-qa, ruwasaq. -qa,
giving the meaning of the condition. Runasimita yachakusqa
tukuspaqa, imatataq ruwasaq, What will I do, when I have learned
Quechua? Tuku-y means to have ended, so when something is done.
(lit. Quechua learned done-ing, what-and do-will-I).
V. Combined with –m or –mi, the
form gets the meaning of because: ni-pti-n-mi, ruwasaq, because
he/she said (it), I will do it. Ni-y is to say. Or: Ni-spa-m
ruwa-nqa, because he says so, he will do it. Ni-pti-n-mi
mana-chu ruwa-nki-man?, would you not do it, because he says (it)?
(lit. say-ing form-he, not (rhetorical) do-you-would?
VI. Combined with –pas, the form gets the
meaning of although: ni-pti-y-pas, mana ruwa-nki-chu, although I
say (it), you will not do (it), or ni-spa-pas, ruwa-nqa,
although he says it, he will do it.
There are some other forms to build complex sentences:
VII. The form –na-personal suffix-kama has the same meaning as –stin, so at the same time. Taki-ku-saq
sama-na-n-kama I will sing while he is resting.
VII. This form can also mean: until. Taki-ku-sa-n-kama
tia-ku-saq, means: until he sings, I will sit here.
VIII. The form –na-personal suffix-rayku
means to express the purpose. This is expressed with verbs that have
motion incorporated in itself: ashka yacha-ku-na-n-rayku Lima-ta
ri-rqa, to learn much, he went to Lima.
Hamu-ra-ni willa-wa-na-yki-rayku: I have come so you can
inform me. Willay is to inform –wa to me, lit:
come-did-I inform-to me-(na=untranslatable)you-because.
IX. With other verbs the form to express the purpose
is: –na-persnal suffix-paq.
Rima-sa-nku taki-na-nku-paq: they are talking (about) what
they will sing.
Taki-sa-ni kawsa-na-y-paq: I sing to live. (I sing so I have
a living). I am a singer.
Yacha-ku-sa-ni rima-na-y-paq runa-simi-ta: I am studying so
(with the purpose) I will be able to speak Quechua.
Llamkasani yachanaykipaq runasimita: I am working so that
you can learn Quechua.
Mana llamkasanichu samanaykipaq punchawnintin: I do not work
so you can be lazy (to rest) all day long.
Asisani kusikunaykipaq: I am laughing so that you will be
With these forms one can build most complex sentences.
Ending (simikuna tukunaypaq)
This is my version of a simplified course in Quechua. I stated before
that this course is by no means complete, but with the accompanying
exercises, I believe that in one month and one hour a day, you should
get on your feet in this language. Thereafter it is up to you to either
take classes or buy some books.
This course will be updated and improved in time. So you might visit
my site again to see where improvements are made.
To end I will give a list of some useful books, along with my
Introduction to Quechua, Language of the Andes, by
Judith Noble and Jaime Lacasa; Passport Books, Lincolnwood (Illinois),
Comment: This is the first book that I got to learn Quechua. The section on grammar is insufficient, but the model
sentences are, when learned by heart, for a beginner a great help. I recorded this book
into my iPod to listen to it whenever I could and wherever I was. The
book comes with 1 cassette that is useful for proper pronunciation. My
critique afterwards is that it contains much "spanquech". It mixes
Spanish and Quechua in a way that is not always helpful for learning the
language proper. (The book is written in 5-vowel)
Quechua, manual de enseñanza, Clodoaldo Soto Ruiz,
3era ed. Lima IEP, 2006. (Lengua y Sociedad 4).
Comment: The book is in Spanish and comes with 2 MP3 discs of in
total about 10 hours of spoken texts and exercises. The grammar is
presented rather casual. The book is mainly practical. My critique is
also that the spoken texts and exercises are spoken too fast for a
beginner. The rather poor sound quality does not help either. The big advantage of this book are its endless exercises, boring in the beginning, very rewarding in the end! (The book is written in 3-vowel)
PS: the problem of the CD's that the language is spoken to fast can be cured by downloading from the internet an audiobook maker program. with such a program one may listen to the exercises (on the same pitch) but they are played slower.

, AO, DoF etc) but we can probably get away with skipping the Albedo, Emissive parts. However you twist and turn it, you will end up with less memory bandwidth and thus better performance. We can also skip ping-ponging when doing bloom and blurs, because we can use a pixel-local cache to save a horizontal blur result when doing a vertical blur, and vice versa.
To enable this in Nebula, we need to add it to the design of a frame shader. A frame shader (perhaps they should have a renderer-specific implementation?) should need a SuperPass tag which can hold many ordinary Pass tags. A would be the Vulkan equivalent of a RenderPass, and an ordinary would be a SubPass. This would allow us to pass 'framebuffers' as input attachments within the and when the ends, we explain what will actually become resolved.
Nebula also needs (with the help of AnyFX) to enable sampler objects in the shader code. In GLSL there are two texture types, sampler1D -> samplerCubeArray and image1D -> imageCubeArray. Samplers would have a sampler attached to it from the application, and images would only be readable through texel fetches. However, in the Vulkan GLSL language there is a new type of texture called, well, texture, and it follows the same range from texture1D -> textureCubeArray. To sample such a texture, we do texture(sampler(AlbedoMap, PointSampler), UV); which is very similar to the DX11 way, which is AlbedoMap.Sample(PointSampler, UV); In the Vulkan GLSL language, we can create a sampler couple when sampling from a texture, which allows the exampled AlbedoMap to be texture sampled using many different samplers without having to exist more than once. However, Vulkan also supports pre-coupled sampler and images, so for the time being, we will stick to that syntax.

How to include R plots and diagrams in blog posts
R plots in Markdown
Using my R-pandoc tool, you will be able to embed nice R plots into blog posts, like the one below! It uses the fantastic pandoc document converter.
require(stats)
D = 150
T = 10
t = seq(0, 80, 0.01)
x = -D*exp(-(t/T))+D
v = (D/T)*exp(-(t/T))
plot(t, x, type="l", main="Evolution of position through time", xlab="time (s)", ylab="position (m)", xlim=c(0,80), ylim=c(0, D+10), xaxs = "i", yaxs = "i")
The above code and diagram are produced by inserting this code block inside a markdown file:
 ''' {.Rplot echo=Above}
 require(stats)
 D = 150
 T = 10
 t = seq(0, 80, 0.01)
 x = -D*exp(-(t/T))+D
 v = (D/T)*exp(-(t/T))
 plot(t, x, type="l", main="Evolution of position through time", xlab="time (s)", ylab="position (m)", xlim=c(0,80), ylim=c(0, D+10), xaxs = "i", yaxs = "i")
 '''
The attribute echo can also get the value Below to get the code displayed below the graphic. Ignore echo if you want only the graphic. Now you can compile your markdown blog post:
$ pandoc -t html demo.md --filter R-pandoc -o demo.html -s
A HTML file should be generated containing a nice graph.
Diagrams in Markdown
Using diagrams-pandoc (available soon), you can also produce nice diagrams inserted in Markdown.
The diagrams above was obtained from the following code:
 ''' {.diagram}
 example = square 1 # fc aqua 'atop' circle 1
 '''
It supports the same options than R-pandoc.
Embed in a Hakyll blog
To embed this in a Hakyll blog, you need to add R-pandoc in the dependencies of you project cabal file, and then define a special markdown compiler:
import Text.Pandoc.R
pandocCompilerR :: Compiler (Item String)
pandocCompilerR = pandocCompilerWithTransformM defaultHakyllReaderOptions defaultHakyllWriterOptions rTransformer
rTransformer :: Pandoc -> Compiler Pandoc
rTransformer pandoc = unsafeCompiler $ renderRPandoc "images" True pandoc
This compiler can be used instead the default one:
buildRmd :: Rules ()
buildRmd = do
 match "*.md" $ do
 route idRoute
 compile $ pandocCompilerR
Combining R-pandoc and diagrams-pandoc
What is really great is that transformers can be composed. To render an article containing both R plots and diagrams in command line, you can do it like that:
$ pandoc demo.md -t json | R-pandoc | diagrams-pandoc | pandoc -f json -t html
To do the same automatically with Hakyll, you can create a markdown compiler from R-pandoc and diagrams-pandoc with the famous fish >=> operator:
myPandocCompiler :: Compiler (Item String)
myPandocCompiler = pandocCompilerWithTransformM readerOptions writerOptions $ diagramsTransformer >=> rTransformer
This blog post has of course been generated with Hakyll, R-pandoc and diagrams-pandoc. Check out the source code here. If you want to learn more about pandoc filters, check here.

The aim of the SFO Stem cells and Regenerative medicine is to support research and infrastructure within the field of stem cells and regenerative medicine.
The call is closed.
Areas of support
The SFO will support researchers, research programs and infrastructure at the Karolinska Institutet (KI) with or without collaboration with the health care system based on scope, quality, and the potential to strengthen and develop the field.
The SFO for Stem Cells and Regenerative Medicine has decided to allocate up to 24 million SEK for 12 research grants according to the same strategy as for previous years. Research grants will be allocated for 2023 but depending on governmental and university decisions successful applicants may be awarded grants for a second year (2024) without new application. Previous and currently supported infrastructures and researchers from SFO Stem Cells and Regenerative Medicine are presented here.
This year's call encompasses basic and clinical research grants. Due to regulations, research grants for this period will be distributed 2023, with a disposition time until 31 Dec 2024. If a second year is granted, the disposition time will end 31 Dec 2025. The exact number of research grants per category will depend on the number of submitted applications, and quality of the applications.
The SFO will during 2023 support up to 6 junior research grants and up to 5 senior research grants for projects within the field of stem cells and regenerative medicine. The senior research grants are open to all candidates and the junior research grants are open to candidates up to 12 years after obtaining their PhD. Applicants should be affiliated 100% at KI and/or the Stockholm County Council (SLL) at the time of starting the project. Applicants who received research grants from this SFO with a disposition right including 2023 are not eligible to apply.
Eligible projects will be supported with a total of 2 MSEK/year. Research grants can be used to cover salaries, running costs, equipment and administrative costs. Indirect costs for the research project specified in the application must not exceed the INDI level at the receiving department. A researcher is limited to submit only one application for a research grant or a clinical research grant.
Clinical research grants
The SFO will during 2023 support up to 5 clinical-translational research grants for projects within the area of stem cells, regenerative medicine and cellular therapies. The call is open to all candidates. These research grants aim at supporting clinically active physicians, who have both an MD and a PhD degree and are affiliated 100% to SLL and KI at the time of starting the project. During the period of research support, the applicant should perform clinical work corresponding at least 20% of full time and be employed as "ST läkare" or specialist at a clinical department within SLL. Examples encompass, however are not restricted to, clinical trials, development of ATMP products or other essential steps for planned clinical trials, correlative biological studies for clinical trials and diagnostic and biomarker studies, all with relevance for the field.
Eligible projects will be supported with a total of 2 MSEK/year. Research grants can be used to cover salaries, running costs, equipment and administrative costs. Indirect costs for the research project specified in the application must not exceed the INDI level at the receiving institution. A researcher is limited to submit only one application for a research grant or a clinical research grant.
Relevance for the field – who can apply?
Research on stem cell biology is important for understanding normal development, homeostasis, and physiological as well as pathological cell turn over. Advancing our knowledge about these processes is critical within regenerative medicine and tissue engineering aiming to develop strategies for regrowing, repairing or replacing damaged cells/tissues/organs/body parts by endogenous or transplanted cells and to treat malignant conditions. Research projects with relevance within the broadly defined areas of stem cells and regenerative medicine are eligible.
Applicants involved in research programs with relevance for the above-described fields are welcome to submit an application.

About 2-coloured 6-graphs.
Let each of the 15 edges of the complete 6-graph be either red or blue. Three of the 6 nodes are said to form a "homogeneous triangle" if the three edges connecting them are of the same colour. Prove the existence of at least two homogeneous triangles.
We call two edges that meet at a node and are of different colour a "mixed pair" meeting at that node. Because at any node 5 edges meet, at most 2 * 3 = 6 mixed pairs meet at that node. Because we have 6 nodes, there are at most 6 * 6 = 36 mixed pairs. Because each mixed pair occurs in one inhomogeneous triangle and each inhomogeneous triangle contains two mixed pairs, we have at most 36 / 2 = 18 inhomogeneous triangles. The total number of distinct triangles being (6*5*4)/(3*2*1) = 20, we have at least 20 - 18 = 2 homogeneous triangles.

The example shows how to use an arrow decorator instance to add an arrow to a path when it is stroked. Instead of using a default arrow instance, we create a highly customized arrow head.
Apart from setting arrow specific features like the arrow size, a list of styles and decorators can be passed to the arrow. In this example, the arrow is stroked in red with round corners. In addition, the arrow is filled in green.
Note that style properties are inherited from the outer towards the inner decorators. In this example, the linewidth is also used when stroking the arrow head. We could for example also skip the color.rgb.green value in the
deco.filled decorator and the arrow would be filled in blue.
To continue removing the deco.filled features, it is equivalent to write
deco.filled. This is due to the fact that
deco.filled already is an instance, which can be modified by call. An empty list does not really modify it. But you could even skip
deco.filled completely and the arrow would still be filled with blue color. The reason is that the arrow is implemented in a way that it always merges the
filled decorator. This step in the evaluation of the attributes is transparent to other settings: if we would replace the
color.rgb.green, we would still get a filled green arrow. You could then remove the
deco.stroked inside of the arrow instance and the line would become green as well. Note that the order of the attributes is not important for this style delegation feature.
Since we have learned that the arrow decorators always fill the arrow head by default, the question is now whether and how such a feature can be removed. This is done by clear instances available as a
clear class attribute. Hence in case of
deco.filled, it is available as
deco.filled.clear. When you add this attribute to the earrow call, the arrowhead will not be filled anymore and you will notice that the blue line is not stroked inside the arrowhead.
You might also have noticed, that the dashed linestyle is not used when stroking the arrowhead. This is similar to the default
filled feature of the arrowhead: The arrowhead merges a
style.linestyle.normal to ensure a solid line. Instead of manually setting
style.linestyle.dashed in the arrowhead, you could use
style.linestyle.clear to restore the linestyle setting of the path.
The arrow head is a so-called ornament. Beside attaching stroke and fill styles during the process of converting a path into a decorated path, any number of ornaments can be added to the decorated path. When adding ornaments, parts of the path can also be marked as not-to-be-stroked. While this is taken into account in a final stroke operation, different decorators do not see this information such that decorators always commute.

We report details of the fluid motion formed within and above grooves when a laminar continuous phase fluid flows over a second immiscible fluid enclosed in a grooved microchannel. Vortical structures within the transverse grooves were caused by a slip velocity at the fluid-fluid interface and act as "fluid bearings" on the boundary to lubricate the flow of the continuous phase. We investigated the drag reduction in the laminar flow in the microchannel by measuring slip at the boundaries and calculating an effective slip length, taking into account the influence of the effect of the viscosity ratio of the two fluids on the effective slip length. The "fluid bearing" effect can be used to transport high viscosity fluids using low viscosity fluids trapped in cavities to reduce drag.

text: At the moment, millimeter waves attract close attention not only of the scientific community, but also of the communication industry. Number of studies worldwide are currently focused on finding efficient solutions for the transceiver technologies compatible with beamforming and carrier frequencies beyond 100 GHz. It was recently demonstrated that the technology of integrated silicon photonic crystals provides decent propagation loss and low fabrication complexity upon implementation of waveguide components for the submmWave band. In this paper, we report on the millimeter wave photonic crystal waveguides fabricated from high permittivity PCB laminate by the means of direct machining. Inspection of the fabricated waveguide samples reveals no violation of the photonic crystal geometry due to the fabrication tolerances. The photonic crystals are designed for operation at frequencies 140–160 GHz, and we measure the power attenuation coefficient attributed to the waveguide geometry of 0.02 dB/mm at 145 GHz. The design considerations, including justification of the laminate choice, and detailed results of performance tests are presented in the paper.


NEWTON — As courthouses and city halls close, there is a logistical problem that arises for governmental boards — just how does the county commission or city council meet?
And, just as important, how do its members host a public meeting and comply with the Kansas Open Meetings Act?
Guidance from the Kansas Department of Health and Environment, and an executive order from Gov. Laura Kelly, limits the number of people in one place at one time to 10. Social distancing guidelines ask those people to stay at least 6 feet apart.
According to Kansas Attorney General Derek Schmidt, the Kansas Open Meetings Act requires public bodies to be "open to the public." Ordinarily, that requirement is met by allowing members of the public to enter the room where the meeting is taking place so they can listen and observe.
The answer to the problem of public governmental guidelines is popping up in meeting notices and agendas. Now appearing are internet links for video conferencing and phone numbers for voice conferences.
For some area government bodies, this is nothing really new. The McPherson City Commission has posted video of its meetings to YouTube, while the Newton USD 373 board of education started streaming live to Facebook on its own earlier this year.
The Harvey County Commission hosted its first online stream this week, making use of the service Zoom to provide video and telephone access. The commission met in the basement of the courthouse as the meeting was streamed.
Under new guidelines issued by the state, each entity will notify the public of the internet location of the meeting during the meeting notification process.
The attorney general's office has proposed formal rules for state and local governments to ensure their meetings remain open to the public during "social distancing" emergency restrictions on gathering in person. Basically, those new rules require for broadcast of the meeting, preferably with video, on either television of the internet or by audio by telephone conferencing.
"During a time of declared emergency when lives are disrupted, many people are apprehensive, and rumors can run rampant, the importance of ensuring openness and transparency in the government decision-making process is even greater than usual," Schmidt said. "An important way for public bodies to provide reassurance is to go the extra mile to ensure their actions are transparent during the time of emergency.
"This new guidance will help state and local government bodies throughout Kansas operate transparently even when the public cannot gather in person for meetings."

THE narrative was, perhaps, just a little too good to be true. When news broke last month of the so-called "Buddha from space" — a swastika-emblazoned statue, apparently 1,000 years old, that had been carved out of a meteorite and looted by a Nazi ethnologist — the world was enthralled.
There were only, it turns out, a few slight catches. According to two experts who have since given their verdict on the mysterious Iron Man, it may have been a European counterfeit; it was probably made at some point in the 20th century; and it may well not have been looted by the Nazis. The bit about the meteorite, though, still stands.
According to Buddhism specialist Achim Bayer, the statue bears 13 features which are easily identifiable by experts as "pseudo-Tibetan" — and which sit uneasily with speculation by researchers last month that it was probably made in the 11th-century pre-Buddhist Bon culture.
These include the 24cm-high statue's shoes, trousers and hand positioning, as well as the fact that the Buddha has a full beard rather than the "rather thin" facial hair usually given to a deity in Tibetan and Mongolian art. In his report, Bayer says he believes the statue to be a European counterfeit made some time between 1910 and 1970.
"Up to date, no acknowledged authority in the field of Tibetan or Mongolian art has publicly deemed the statue authentic…," writes the University of Seoul academic.
The statue's Asian provenance is not the only aspect of the story to have been questioned. In September, the man leading a team of German and Austrian researchers, University of Stuttgart geologist Elmar Buchner, said its previous owner had claimed it had been brought to Europe in the late 1930s by Ernst Schafer, a Nazi ethnologist who led an SS expedition to Tibet.
But German historian Isrun Engelhardt, who has studied Schafer's trip to Tibet in depth, has cast doubt on this suggestion, questioning the statue's absence on the long list of items brought back. "There is an extremely precise list of the purchased objects, including date, place and value," she told Spiegel.
Buchner says he had no reason to doubt the account of the previous owner, and stresses that his team was only looking into what the statue was made of — a rare form of iron with a high content of nickel — not where it had come from. While they felt able to say the material most likely came from the Chinga meteorite, which crashed to earth 15,000 years ago, the researchers admitted that "the ethnological and art historical details — as well as the time of sculpturing, currently remain speculative".
Moreover, Buchner's statements about the origins were qualified. He told the journal Meteoritics and Planetary Science: "If we are right that it was made in the Bon culture in the 11th century, it is absolutely priceless and absolutely unique worldwide."

We know that a six base pair sequence AGAATA occurs 1 time in 4096 nucleotides [ (1/4)^6 = 4096 ] correct?
Let's say we have a DNA library that is 50,000 base pairs in total (small library of 50 clones to keep numbers small) it should occur roughly ~12 times [ 50000/4096 = 12.2 ] with 100% probability?
1. What is the probability that it would occur twice? How about 5 times?
2. What is the probability it would occur once in a single clone from this library if the clone is 500 bp long? What about twice?
3. And finally, let's say AGAATA occurs 3 times in one 500 bp clone. Is this significant? What is the equation? I wanted to know basically, "This six base pair sequence has an X-percent probability of occurring within the clone, and an x-percent probability of occurring in the whole library. Thanks.

Architecture Images-Sydney Architects
Barnet, James Johnstone (1827 - 1904)
Born: 1827 Scotland. Died: 1904.
James Johnstone Barnet was clerk of works at the University of Sydney _PHONE_. In 1860 Barnet joined the office of the Colonial Architect, becoming its permanent head in 1865 after acting in the position for two years. As Colonial Architect Barnet was responsible for many of Sydney's significant public buildings until his departure in 1890.
|"The greatest of
all Colonial Architects"
James Barnet was born in Scotland and studied drawing, design and architecture in London before he sailed for Sydney with his wife Amy in 1854. He lived all his Australian years in Glebe (Derwent Street in 1865) and Forest Lodge (Braeside, now demolished).
In 1860, Barnet joined the Colonial Architect's Office. In 1865, he became Colonial Architect and served in this position for 25 years. Barnet's work in Sydney signalled its maturation from a Georgian town to a Victorian city. His work contributed to a sense of stability and civic pride and includes :
The Australian Museum (1864)
The GPO in Martin Place (1866-90)
The Colonial Secretary's building (1878)
The Lands Department building (1876-81, 1888-93)
Further afield, Barnet designed 169 post and telegraph offices, 130 courthouses (including the Glebe Courthouse (1889)) and many other public buildings across the state.
Glebe Courthouse with the police station in the background.
Barnet was 'a promoter of new technologies, used concrete and fire-resistant materials, introduced electricity into his buildings and was first to install a telephone in a government office.' Chris Johnson, the current Government Architect, states that Barnet was the Colonial Architect who most significantly affected the shaping of Sydney.
James Barnet has left Sydney a legacy of iconic and much-loved Victorian buildings. He died at Forest Lodge aged 78 on 16 December 1904 and was buried at Rookwood Cemetery.

Poy Sang Long
The Poy Sang Long (Shan: ပွႆးသၢင်ႇလွင်း; lit. "Festival [of the] Crystal Sons") is a rite of passage ceremony among the Shan peoples, in Myanmar (also known as Burma) and in neighbouring Northern Thailand, undergone by boys at some point between seven and fourteen years of age. It consists of taking novice monastic vows and participating in monastery life for a period of time that can vary from a week to many months or more. Usually, a large group of boys are ordained as novice monks at the same time.
It can also be observed in neighbouring Thailand, where Shan immigrants have brought over the traditions from Myanmar. The ceremony goes on for three days, as the boys (dressed up like princes in imitation of the Lord Buddha, who was himself a prince before setting out on the religious path) spend the entire time being carried around on the shoulders of their older male relatives. On the third day, they are ordained, and enter the monastery for a period of at least one week, and perhaps many years.

text: Engineering problem solving requires both domain knowledge and an understanding of how to apply that knowledge. While much of the recent work in qualitative physics has focused on building reusable domain theories, there has been little attention paid to representing the control knowledge necessary for applying these models. This paper shows how qualitative representations and compositional modeling can be used to create control knowledge for solving engineering problems. This control knowledge includes modeling assumptions, plans and preferences. We describe an implemented system, called TPS (Thermodynamics Problem Solver) that illustrates the utility of these ideas in the domain of engineering thermodynamics. TPS to date has solved over 30 problems, and its solutions are similar to those of experts. We argue that our control vocabulary can be extended to most engineering problem solving domains, and employed in a wide variety of problem solving architectures.

In this article, learn how to take a screenshot on Samsung Galaxy phone.
On the Samsung Galaxy A12, find out how to snap a screenshot (SM-A125F). If you're like most people, you probably use your phone to snap a lot of screenshots for numerous reasons. Perhaps you'd like to show something to your friends, or perhaps you'd like to save something for later. Regardless, taking screenshots is a critical capability that all Android phones, including the Galaxy A12, have.
If you've recently purchased a Samsung Galaxy A12, you may be wondering how to take a screenshot. The methods for getting screenshots on most Samsung phones are the same or similar. This article may be familiar to you if you have previously used a Galaxy device. Learn how to snap a screenshot if you haven't before.
How To Take a Screenshot on the Samsung Galaxy A12
Samsung has included three different methods that users can use to take a screenshot on the Galaxy A12. The first method, which is also the most popular one, is the traditional way of pressing two hardware keys at the same time. The two other methods include Samsung's own software to make it even easier.
1. Galaxy A12 Screenshot – Hardware Keys
The physical keys on the side of the phone are the first option for taking a screenshot on your Galaxy A12. This is the most commonly used traditional approach.
Grab your phone and simultaneously tap the power and volume down buttons. Wait until the screen flashes white before releasing the keys. This signifies that you've captured a screenshot. A little menu bar will appear at the bottom of the screen after the screen goes white. There will be three buttons on the menu. The first button allows you to crop and alter the image. The second and third buttons enable Scroll Capture and post the image on social media, respectively.
2. Galaxy A12 Screenshot – Palm Swipe to Capture
If the first approach fails due to broken buttons or another issue, you can use the "Palm Swipe to Capture" feature on your Galaxy A12 to take a screenshot. This is Samsung's method, which does not necessitate the use of a mechanical button.
Go to Settings -> Advanced Features -> Motions and Gestures to enable Palm Swipe. There will be a capturing option called Palm swipe capture. By default, it is turned off. Toggle it on by tapping it. To snap a screenshot, swipe your hand across the screen. When the task is completed, the phone will vibrate to signal that it has been completed.
3. Galaxy A12 Screenshot – Assistant Menu
If you're looking for something a little more user-friendly, consider Assistant Menu. If all of the hardware keys on your Galaxy A12 are broken and nothing else works, this is your last option.
Navigate to Settings > Accessibility > Interaction and dexterity and tap on the Assistant menu to enable Assistant Menu. A little circle will appear on the screen. Press on the circle. A menu of choices will emerge. Select Screenshots from the drop-down menu. When the screen flashes white, it means a screenshot has been taken.
On the Samsung Galaxy A12, there are a few different ways to take a screenshot. When the hardware buttons are broken, Samsung has included a few software functions that allow you to take screenshots. Do you have any other options for capturing a screen? Let us know in the comments section below.

BARD (thief subclass)
Bards are an interesting group. They are, essentially, a melding of
fighters, thieves, and song masters. While adept at the skills of
both combat and larceny, a bard's primary power is derived from
offensive and defensive "songs." The bard undergoes rigorous training
to learn how to use words, melody and counterpoint to effect changes
in their environment. Bards can use their songs to hurt, to charm, and
to inspire as well as to understand the nature of objects around them.
As a hybrid of classes, a bard has the gift of both fighter and thief
abilities, but does not possess the full range, nor the full strength
of the abilities of a true member of either class.
Bards are charismatic and joyous adventurers. They are known
throughout the lands for regaling the folk with tales of their
journeys. As such, many shopkeepers reward bards by paying a higher
than usual price for a bard's goods. Shopkeepers may do this to
assist the bard in further adventuring and in hopes of the bard
returning with more glorious tales.
A bard only performs one song at a time, but is capable of improvising
with refrains that adjust the mood and keep the audience on their
Bards can not wear gloves, shield or plate helmet.
Bards have the following skills:
sleight staff toughness awareness
resistance disarm bow dagger
sword axe singing combat
spear mace flail
Bards have the following songs; the (*) indicates a refrain:
charm fear vengeance rejuvenation
lore * dirge * quell * inspire

Consider the Weierstrass cubic $$y^2z = x^3 + A\, xz^2+B\,z^3.$$ This defines a curve $E$ in $\mathbb{P}^2$, which if smooth is an elliptic curve with basepoint at $[0,1,0]$.
I'm interested in having an explicit description of the locus of $p$-torsion points of this curve, where $p$ is prime.
In fact, suppose $p\neq 3$. Then ideally I'd like to be able to find a curve $C$ in $\mathbb{P}^2$, given by an equation $f=0$ of degree $d=(p^2-1)/3$, so that the scheme $X=E\times_{\mathbb{P}^2} C$ is precisely the locus of points of exact order $p$.
Example: For $p=2$, it's well known that $f=y$ gives such a curve.
I'd like $f$ to be an expression which depends on $A$ and $B$; i.e., I want to do this over a generic part of the moduli stack. I would also like this expression to work in characteristic p; in this case, $X$ should turn out to be the "scheme representing Drinfeld level structures $\mathbb{Z}/p\to E$". (Edit: I'm particularly interested in families of curves which include supersingular curves.)
(My example curve $E$ is never smooth in characteristic $2$, but if you consider a more general Weierstrass form which is smooth in char. $2$, then you can find a degree $1$ curve $C$ which does what I ask. For instance, if $E: y^2z+A\,xyz+yz^2=x^3$, take $f=A\,x+2\,y+z$.)
So my questions are:
 1. Is it usually possible to find an equation $f=0$ such that $E\cap C$ is exactly the $p$-torsion? (Is this the same as asking that $X$ is a complete intersection?) Can you ever show it's not possible?
 2. Are there known methods for computing the locus of $p$-torsion points explicitly? Are there software packages which do this? (I'm aware there are ways to find explicit torsion points on elliptic curves defined over some field or number ring; I'm asking for something a little different, I think.)
 3. Have people carried out these sorts of computations for various small values of $p$ (even $p=5$), and are these computations described in print? (I'm probably most interested in this question.)
Warning: I am not an algebraic geometer or number theorist.

That's not the best wikipedia page. "The division polynomials form an elliptic divisibility sequence." is mentioned well before the far more important "the roots of then'th division polynomial tell you the n-torsion in the curve".

PS finite flat group schemes are always complete intersections ;-) – Kevin Buzzard Mar 4 '10 at 16:56
Okay, I will look into that! I'm worried it's not what I want, though. The roots of the division polynomial $\psi_p$ are the $x$-coordinates of the $p$-torsion points, which means it degenerates in characteristic $p$ to something of smaller degree; it will never give the thing I want if the curve is supersingular, for instance. But since the algorithm seems to give a formula for $[n]:E\to E$, maybe I can get what I want out of it... – Charles Rezk Mar 4 '10 at 17:13
I'll tell you a formula for [n]:E-->E; it's [n-1]+[1]. This works even in characteristic $p$. I am wondering whether if you think hard enough about this trivial observation that it will solve your problems without actually having to do any computations... – Kevin Buzzard Mar 4 '10 at 17:27
To be honest, perhaps the main contribution of the answer is telling you what to google for, rather than anything else... – Kevin Buzzard Mar 4 '10 at 17:29
PS _USER_: I've just realised that I don't understand your comment earlier about degenerations. You absolutely want the p'th division polynomial to degenerate mod p, because in characteristic p the identity of the group (the point at infinity) is a root of the equation [p]P=0 with multiplicity at least p, and hence you want some of the roots of the polynomial to go off to infinity, which is exactly what is happening. – Kevin Buzzard Mar 4 '10 at 17:39
Since you asked about software, I'd just like to point out (if you don't know already) that SAGE (available at sagemath.org) can compute division polynomials easily. The commands
R. = PolynomialRing(GF(5))
E = EllipticCurve([A,B])
f = E.division_polynomial(5)
return the result
2*A*x^10 - A^2*B*x^5 + A^6 - 2*A^3*B^2 - B^4.
The warnings of the commenters apply; you must be cautious about interpreting the division polynomials. It is true that the roots of this polynomial give you the "physical" 5-torsion points of the elliptic curve in characteristic 5, but that's about all it says. The polynomial does not tell you, eg, the structure of the group scheme E[5] over the supersingular locus.
A little more helpful might be the formal group associated to this family:
G = E.formal_group()
which returns
2*A*t^5 + (2*A^6 - A^3*B^2 - B^4)*t^25 + O(t^30)
There's also a command G.group_law() whose output I'm not going to give here. Together these data give you the structure of E[5] over an infinitesimal neighborhood of the zero section of your elliptic curve over $\text{Spec}\mathbf{F}_5[A,B,\Delta^{-1}]$.
I'm a firm believer in explicit calculations as a means of developing intuition about algebro-geometric concepts. But by all means read Katz-Mazur :-).

Here is an attempt to answer my own question, using the "division polynomials" of Kevin's and Jared's answers. It is probably the maximally naive idea, and I do not claim it works, though it's not clear to me that it can't. I've community wiki-ed this answer, as it's probably junk anyway...
Fix $A,B\in \mathbb{Z}$, obtaining an elliptic curve $E$ over $S=Spec \mathbb{Z}[\Delta^{-1}]$, and a prime $p\geq 5$ not dividing the discriminant $\Delta=\Delta(A,B)$. The division polynomial $\psi_p(t)$ is supposed to be a polynomial of degree $d=(p^2-1)/2$ over $\mathbb{Z}$, whose roots are the values $t(P)=x(P)/z(P)$ as $P$ ranges over the points of exact order $p$ in $E$.
Turn $\psi_p$ into a homogeneous polynomial $g$ of degree $d$ in $\mathbb{Z}[x,y,z]$, so that $g(x,y,1)=\psi_p(x)$. The polynomial deterimes a curve $C=(g)$ in $P^2/S$, and thus a closed subscheme $D=E\cap C$ of $E$. Over $\mathbb{Z}[\Delta^{-1},p^{-1}]$, $D$ should consist of the points of exact order $p$ on $E$ (with multiplicity $1$), together with the basepoint of $E$ with multiplicity $d$.
Claim. $D$ is an effective Cartier divisor on $E/S$, of degree $3d$.
Proof. I don't know. I need to prove that $D\to S$ is flat, the main concern being the behavior over $\mathbb{Z}_{(p)}$. I don't even know if this is really plausible in general.
Let's pretend we somehow know $D$ is an effective Cartier divisor on $E$ relative to the base $S$. There is another relative Cartier divisor, namely $$ D' = E[p] \quad + \quad (d-1)[0]$$ where $E[p]$ is the $p$-torsion subgroup scheme of $E$, and $[0]$ is the degree one divisor of the basepoint of $E$. It seems clear that away from characteristic $p$, the divisors $D$ and $D'$ are equal. Equality of effective divisors on a smooth curve is a closed condition, so they should be equal over all of $S$.
The divisor I want is thus $D''=D-d[0]=D'-d[0]$ (which is still effective). Then it's really easy to find

To do this, set up the multimeter's dial to the hertz (Hz) value and connect the black test lead jack to the black ignition coil.
Take the reading value after turning the engine for one minute.
Multiply the value by 60 seconds to get the engine's RPM. Another way to measure RPM with a multimeter is using an inductive pickup.
For example, you can use Trisco DA 830 and plug the inductive pickup into the multimeter.
Plug the black lead into the COM jack and the red lead into the RPM INDUCTIVE jack.
Turn the measurement mode switch to the RPM position.
It's important to note that using a multimeter to measure RPM may not be as accurate as using a tachometer specifically designed for this purpose.
However, a multimeter can still provide a rough estimate of the RPM and help diagnose issues with the engine.
What Are The Different Methods Of Measuring RPM With A Multimeter?
To measure RPM with a multimeter, a few methods can be used.
One method is to set up the multimeter's dial to the hertz (Hz) value and connect the black test lead to the ground and the red test lead to the signal wire.
The Hz reading can then be converted to RPM using a conversion formula.
Another method involves using a multimeter to measure the frequency of the engine-generated signal and then converting the frequency to RPM using a conversion formula.
For example, if using a multimeter to measure RPMs on a 4-stroke engine (without 'wasted-spark'), the reading must be multiplied by 120, 60 seconds per minute.
If the multimeter has an HZ or FREQ function, it may be possible to calculate engine RPMs with the right amount of fussing and experimentation.
It's important to note that these methods may not be as accurate as a dedicated tachometer and may require some calibration or adjustment to get accurate readings.
Additionally, it's worth mentioning that there are other methods for measuring RPM, such as using a handheld tachometer or the tachometer built into the vehicle.
Can You Explain How To Use The Frequency Measurement Method To Measure RPM With A Multimeter?
Here are the steps to measure RPM using a multimeter:
- Set the multimeter to the "Hz" setting, which measures frequency.
- Connect the black test lead to the COM jack on the multimeter.
- Connect the red test lead to the signal source, usually the ignition coil or spark plug wire.
- Start the engine and let it run at a constant speed for at least one minute.
- Read the frequency measurement in the display of the multimeter.
The abbreviation "Hz" should appear to the right of the reading.
- To convert the frequency value into RPM, multiply the frequency by 60 (since there are 60 seconds in a minute) and divide by the number of pulses per revolution.
Note: The number of pulses per revolution depends on the type of engine and the number of cylinders.
For example, a 4-cylinder engine has 2 pulses per revolution (one for each spark plug), while a 6-cylinder engine has 3 pulses per revolution.
Could You Provide More Details On Using An Inductive Pickup With A Multimeter To Measure RPM?
To measure RPM using an inductive pickup with a multimeter, follow these steps:
- Purchase an inductive pickup lead designed for adjustment and diagnosis of RPM.
- Set your multimeter to the "HZ" setting so that it can measure frequency.
- Connect the inductive pickup lead to your multimeter.
- Place the inductive pickup lead around the spark plug wire of the engine you want to measure the RPM of.
- Start the engine and let it run for a minute.
- The multimeter should now display the RPM of the engine.
Some multimeters, such as the Fluke 88V, come with an inductive RPM pickup and can measure RPM in either the DC or AC volts function.
Maintenance meters are available that can read RPM and calculate hours off detection of the electrical emissions from the spark plug wire.
What Are The Limitations Of Using A Multimeter To Measure RPM Compared To A Tachometer?
Using a multimeter to measure RPM has some limitations compared to using a tachometer.
Here are some points:
Limitations of using a multimeter to measure RPM:
- A multimeter can only measure electrical properties, such as voltage, resistance, and current.
To measure RPM, a multimeter must be able to measure frequency, which is not a standard feature on all multimeters.
- A multimeter may load the circuit under test to some extent, which can affect the accuracy of the measurement.
- When using a multimeter to measure RPM on a 4-stroke engine (without 'wasted-spark'), the reading must be multiplied by 120 to get the correct RPM.
- Some limitations regarding digital multimeters for automotive diagnostics include additional pick-up to measure engine RPM and extreme accuracy is not required for most routine testing.
Advantages of using a tachometer:
- A tachometer is specifically designed to measure RPM and is, therefore more accurate than a multimeter.
- A tachometer can measure RPM on a wider range of engines, including 2-stroke engines and engines with wasted-spark ignition systems.
- A tachometer does not load the circuit under test, which means it does not affect the accuracy of the measurement.
Are Any Other Tools Or Devices More Accurate Than A Multimeter For Measuring RPM?
Yes, some other tools or devices are more accurate than a multimeter for measuring RPM.
Here are some examples:
- Tachometer: A tachometer is a device that measures the rotation speed of a shaft or disk and is designed to measure the revolutions per minute (RPM) of a moving object.
Handheld digital tachometers offer precise rotational speed measurements in various models.
Cheaper models may give you more accurate readings than an average tachometer.
- Digital laser tachometer: A digital laser tachometer is a non-contact electronic tachometer that can measure RPM accurately to +/- 0.02 percent.
- Strobe tachometer: A strobe tachometer is a device that uses a flashing light to measure the RPM of a rotating object.
When choosing a tachometer, consider the following factors: the type of object you wish to measure, whether you need a contact or non-contact device, and the measuring range and accuracy required.
My name is Robert Phillipson, and I am an Electrical Engineer with 20 years of experience in the field. My fascination with multimeters began early on during my career as I was captivated by their precision and accuracy. Over the years, I have gained a deep understanding of how they work, enabling me to use them effectively for measurement applications like testing circuit boards and other components.

A Tingling Sensation In The Abdomen And Thighs When Exercising With Weights?
Hello, I want to ask you.rnWhy do my stomach and thighs have a tickling sensation when I do sports movements that use weights?rnrnPlease enlighten me, thanks!
Sport is one part of efforts to maintain health. Exercise using your own weight has a variety of goals ranging from maintaining fitness to increasing muscle strength.
What you are experiencing could be caused by uncomfortable clothes. Uncomfortable clothing can cause discomfort ranging from tingling to possibly painful during exercise.
In addition, because you practice using weights, it could be that an incorrect position or method can also be a trigger, causing the activities you are doing to be inappropriate with your body's physiology, causing discomfort.
Since you're using weights in your workout, make sure you warm up enough to start adding more intensity to your workout. Otherwise, your body will have difficulty keeping up with the weight and intensity of your workout, causing the discomfort you experience.
It's a good idea to learn the procedures for training with weights well before starting the exercise or learning from a trained trainer. This is useful so that your exercise is effective and reduces the risk of injury.
I hope this helps.


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

Example sentences for: jararaca
How can you use "jararaca" in a sentence? Here are some example sentences to help you improve your vocabulary:
 - While proteases, phospholipase A 2 and nucleotidases are responsible for the haemorrhagic lesions induced by Bothrops jararaca venom, most crotalid myotoxins are phospholipases and some exhibit proteolytic activities [ 12 ]. Crotalid snakes have a wide geographical distribution, this may contribute to differences in their venom composition [ 8 ]. Differences in venom composition may play a role in the effectiveness of the medicinal plants used for snakebites.
 - The in vitro myotoxicity of the crotalid venoms venoms ( Bothrops jararaca, Bothrops jararacussu and Lachesis muta ) and myotoxins (bothropstoxin, bothropasin and crotoxin) was neutralised by simultaneous exposure of isolated skeletal muscles to an aqueous extract of Eclipta prostrata or to wedelolactone, stigmaterol and sitosterol.
 - Ethanolic extracts of the aerial parts of Eclipta prostrata (Asteraceae) neutralised the lethal activity of the venom of South American rattlesnake ( Crotalus durissus terrificus ), as well as the myotoxic and haemorrhagic effects of B. jararaca, B. jararacussu and Lachesis muta snake venoms when mixed in vitro before i.p.

Exhibition recognises sugar's Pacific foundation
Updated June 19, 2013 17:21:27
Audio: Queensland Art Gallery curator of Pacific art Ruth McDougall talks about the 'Sugar' exhibition. (ABC Rural)
The earliest days of the sugar industry and its dependence on workers, willing and unwilling, from the Pacific are on show in Brisbane.
Postcards, photographs, music and recorded anecdotes have been pulled together to mark 150 years of Australian South Sea Islander contributions to Queensland.
Ruth McDougall is the Queensland Art Gallery's curator of Pacific art and says some of the postcards in the collection date from the 1870s.
"These were lithographs majorly produced for sending overseas to really promote Queensland as a destination for investors and sugar was a major part of that promotion exercise.
"And you see from those very early images that the South Sea Islanders are right in there, that they are part of the story of sugar from the beginning."
The workers came from islands in Melanesia, including Vanuatu and the Solomons, and from Polynesian and Micronesian islands such as Samoa, Tuvalu and Kiribati.
Ms McDougall says some were contracted to work in Australia but most, including young children, were kidnapped.
"The term that South Sea Islanders use is 'blackbirding'.
"Quite often they were enticed from the beach onto the ships and when they arrived they were adopted and worked as domestics or were taken out to cattle stations to work as well."
Frank Robert Boah, known as Bobby, from Mackay features in one of the recordings which forms part of the exhibition.
He's visited the village where his grandfather was born and heard how he was taken from a reef.
"The ones that were close to shore, they ran away up into the scrub or the forest.
"But me grandfather was too far out and they caught him.
"There's a lot of people don't know, they think we're Aboriginals because of course we're dark.
"But we've got a different history altogether."
Ms McDougall says after Federation in 1901, and the start of the White Australia Policy, all bar 1600 of the South Sea Islanders were deported.
The exhibition called 'Sugar' is running until October 7 in Brisbane.

Kill zombie nouns in three easy steps
Zombie nouns are one of the most common problems I see in non-fiction writing. By learning how to identify and replace zombie nouns, you'll instantly improve the quality of your writing. And your readers will thank you for it!
Nominalisations, or zombie nouns, are nouns formed from other parts of speech like adjectives or verbs. They are called 'zombie nouns' because they suck life out of speech — replacing words we understand with abstract entities we don't.
Academic, legal and government writing is often cluttered with zombie nouns. Here's an example of some writing with the zombies highlighted:
A recycling project investigation is being led by Council officials in partnership with relevant government departments. This investigation will be used for the preparation of a business case with the aim of securing the Council's approval at its next meeting. The business case will describe recycling-scheme affordability and household-collection feasibility. Subject to stakeholder feedback and Council approval, the project will proceed to implementation in the New Year. The project has good alignment with the government's waste-reduction priority. Risks to the project's achievement will be monitored during implementation through a risk-monitoring process.
By converting plain words and phrases into zombie nouns, the writer has created several problems:
 - The writing sounds pompous and abstract.
 - The writing is hard to understand.
 - The writing uses complex terms that may be understood differently by different people (even within the same organisation).
Have a look at your organisation's documents, manuals or websites to see if this problem exists where you work. If it does, don't worry — zombie nouns are easily fixed!
Step 1: Take a piece of writing and list all the zombie nouns you can find.
Step 2: List the corresponding verb or adjective that you used to make each zombie noun. Here's a list of the words from our example paragraph:
Zombie noun Original verb or adjective
Investigation To investigate
Preparation To prepare
Aim To aim for
Approval To approve
Recycling-scheme affordability Affordable (adjective)
Household-collection feasibility Feasible (adjective)
Feedback To feedback or to give feedback
Implementation To implement
Alignment To align with
Waste-reduction priority To prioritise
Achievement To achieve
Risk-monitoring process To monitor
Step 3: Rewrite your work using the original verbs and adjectives.
Here's the same example, but this time the zombie nouns have been replaced by their original verbs or adjectives.
Council officials and relevant government departments are investigating ways to improve recycling. They will then prepare a business case for the Council to approve at its next meeting. The business case will explain how to make recycling affordable and whether it's feasible to collect recycling from households. If the Council approves the business case, and stakeholders support the project, the Council will implement it in the New Year. The Government has prioritised reducing waste, and this project aligns with that goal. As the Council implements the project, it will monitor any risks that could prevent it achieving its objectives.

Potterton Commercial joins trend to centralised heating plant for residential blocks
Served by hot water from central plant, Potterton Commercial's Sirius 'heat box' is supplied with hot water from central plant and uses two plate heat exchangers to provide heating and hot water for individual dwellings in a residential block.
Potterton Commercial has responded to the trend towards centralised heating and hot-water solutions in multi-occupancy residential development with the launch of the Sirius SAT 'heat box'. These units provide heating and hot water for individual dwellings in a block of flats served by a central plant room. The benefits of this centralised method of providing heating and hot water include reduced installation costs, fewer flues and visible plumage and reduced costs for annual servicing of individual boilers. It is also easier to integrate low- and zero-carbon solutions with central plant, such as the Andrews Solarflo solar thermal system. There are eight sizes of Sirius SAT heat boxes. Their integral heat meters can transmit data wirelessly, enabling the consumption of heating and hot water in each dwelling to be monitored from a single position, reducing reading costs and avoiding potential reading mistakes. The consumption of energy in each dwelling is shown on a digital display to help encourage efficient use. Options include programmable room thermostat, weather-compensation module and DHW/cold-water meter and pipework loop.

Sumpu Castle Park
A beautiful park in the heart of the city, where you can also experience tea ceremony.
Sumpu Castle Park is located on the former site of Sumpu Castle, which was originally constructed in 1585. The castle was famous as the home of legendary Shogun Tokugawa Ieyasu, who spent his twilight years here in the early 17th century. The castle grounds' turrets and East gate have been restored, reminiscent of how they appeared 400 years ago. The park is surrounded by stone walls and two moats, and is a popular resting place for locals. Locals enjoy jogging picnic and strolling. The park is also home to Momijiyama Garden, where you can get a taste of authentic Japanese culture. There are four Japanese gardens and a teahouse where you can experience tea ceremony. Enjoying a cup of green tea while gazing out on the beautiful garden, you are sure to feel closer to the traditional culture of Japan.

While you may love the look of pristine white plastic items, they will show their age over time. When white plastic gets old and dirty, it tends to take on a yellow hue. Sometimes plastic turns yellow because of excessive sun exposure, while other times the yellow colouring is because of age, heat exposure or dirt. Often, the yellowing is evidence of chemical changes that have occurred in the plastic. If this is the case, you will not be able to get the plastic completely white again. In most cases though, you will be able to lighten the yellowing and improve the item's appearance.
Place the plastic item in a container of warm, soapy water and allow it to soak for 10 minutes.
Use a nylon scouring brush to clean the plastic. Apply steady, even pressure as you clean.
Rinse the item under cool running water to remove the debris you loosened.
Pour hydrogen peroxide over the plastic and scrub with the brush. Hydrogen peroxide will help to lighten the yellowed areas significantly. You can also allow the item to soak in the peroxide for up to two hours.
Create a mixture of 4 tablespoons of bleach and 4 cups of warm water. Soak the plastic in the solution for half an hour. Rinse the item under cool water thoroughly after removing it.
Let the plastic air dry. If the plastic is still yellow, repeat soaking processes.
- Some yellowing is irreversible. If you can't remove the yellow from the plastic, consider painting the item.
- Wear gloves when handling bleach; it can irritate the skin.
