Cara Delevingne Style Analysis
Cara Delevingne, known for her acting and modeling career but also has some less-known facts that help her stand out even more. From her battle with depression and body image, to her ventures to the world of sexual toys and her willingness to talk about her pansexuality, here are 10 interesting facts about the multi-talented Delevingne.
Despite her beautiful appearance, Cara Delevingne struggled with depression and insecurity about her body during her teenage years. She was ridiculed for her small chest and started menstruating later than her peers and was referred to as "frigid" and "flat". At the age of fifteen depression struck her and she had to temporarily quit school. In an interview with BBC she discussed her time in which she stated, "I hated myself for being depressed, I hated feeling depressed, I hated feelings." However, Delevingne came from a very well-to-do family and everybody believed she should be automatically happy, they were unable to comprehend her mental state.
Cara Delevingne had a difficult time understanding her sexuality, growing up in a family where it was not discussed. For a while, she found same-sex partnerships to be demeaning and considered her self-defence homophobic. In an interview with The Guardian, Delevingne said, "I know I'm the luckiest girl in the world, I understand all this and I wish I could appreciate it. It's just that there's something dark inside me that I can't shake."
Delevingne considers herself pansexual and loves the person, regardless of their gender identity. She said that she may also be attracted to non-binary and transgender individuals. In an interview with Variety, Delevingne said, "However an individual identifies, whether it's a 'they', a 'he' or a 'she', I fall in love with the person – and that's what it's about. I'm attracted to the person as such."
In 2019, Delevingne got married in Las Vegas to actress Ashley Benson however, they later broke up. She's also been romantically connected to actress Michelle Rodriguez and singer Miley Cyrus. The public display of Delevingne's sexuality has received both support and criticism.
Delevingne was a target of producers Harvey Weinstein, who threatened her career if she didn't cover up her sexuality and find male partners to be a "cover". However, Delevingne didn't listen, and she continued to be open about her sexuality and relationship.
Delevingne has a business venture with a toy company for sex and is the one who personally tests the products. She is open and unashamed about her involvement in the business and regards it as an opportunity to spread the message of sexual health and freedom.
Delevingne has a hidden vaginal tunnel in her villa it was a gift from a close friend. The tunnel was designed by an artist, and is an emblem for female power and liberation.
Delevingne recently stepped into the world of NFTs by creating a video of her dancing in the secret vaginal tunnel in her villa and sold it as a special digital collectible. The video showcases her daring and unflinching personality and her determination to explore new avenues and break boundaries.
Despite some criticisms of her acting ability she continues to pursue her love of acting. She's appeared in several films and TV shows, including "Valerian and the City of a Thousand Planets," "Suicide Squad" and "Carnival Row" It is evident that she's not confined by the opinions of others about her talents and skills and is constantly challenging herself.
Delevingne's story has been an inspiration to many. She's been candid of her personal struggles as well as her progress towards self-acceptance, she is an example for others on the importance of being true to oneself regardless of what other people might think or think. She has spoken out about body positivity and inclusiveness and has used her platform to advocate on behalf of marginalized communities. Her actions show that it's okay to not be able to do everything right and that it's okay to be different and individual.
Cara Delevingne began her career as model at 10, signing with Storm Model Management. The model quickly gained fame and was soon among the highest sought-after models in the industry, walking for top designers such as Burberry, Chanel, and Fendi. She's an example of how you can go from being a model into an established brand, and also how to make a name for oneself in the fashion industry.
Delevingne is also well-known for her charitable work, she has been a global ambassador for Women's Cancer Research Fund and actively supports mental health charities and organizations including, The Samaritans and the National Alliance on Mental Illness. Additionally, she has donated to organizations that fight against racism and discrimination.
Delevingne has also been a professional musician and she has released several music videos and songs. She has collaborated with different artist such as Pharrell Williams.
Delevingne has a large following on social media. She's known for her candid posts and relatable content which have helped her build a number of followers and fans.
Delevingne has successfully transformed from being a model into an actress, and has been praised for her performance in films like "The Face of an Angel" and "Tulip Fever".


Friday Flashback: Christmas in August?
Picture a bright, hot, cloudless August afternoon. We actually had a few this year so it shouldn't be too hard. Now picture me coming out of my house, clad in a tank top and shorts (that may be a little tougher to picture, but please refrain from laughing as you do so), admiring my flower bed resplendent with blooming – better make that "wilting" – pansies, and full, brilliant orange marigolds; and then skittering barefoot across the shimmering hot concrete driveway as I make my way to my mailbox. As I open the door to the mailbox, which incidentally is still not speaking to me, my greatest hope is that someone has mailed me a tall iced tea in a frosted glass with a fresh lemon slice twisted decorously atop the rim. Instead, I reach into the box and find… a Christmas catalog!!!
Talk about befuddlement. But hey, there are a limited –albeit plentiful – number of shopping days 'til Christmas, so I find a cool spot in the shade and delve right into the toy section of the catalog. Maybe if I find some toys that both the kids and I like, I won't mind so much having to pick them off the floor every day.
My girls are so young that they're relatively easy to please. As long as it's pink, Catherine will love it. And as long as it is sturdy enough to withstand a tug-of-war between my two little angels, Annie might actually get to play with it sometimes.
I'm glad I'm starting early. Toys have changed since I was a kid, so the selection is more complex than merely weighing the relative virtues of Lincoln Logs and building blocks.
I remember talking dolls that said, "Hi, my name is ____." Or "Would you like to play with me?" These days one hip chick says "You got it, Dude," and a doll named "Urkel" is quoted to quip "Hee-Hee-Hee, Snort!" I guess I don't watch enough TV to keep up with doll linguistics.
The stuffed animals haven't changed much over the years, except for a few novelties. The "patch-up pets" kitty is kind of cute. It comes with a medical kit and bandages so kids can play doctor. The doll also "comes with her own 'injuries,'" but I bet any kid can provide injuries that that stuffed kitty never dreamed possible in all her nine lives.
Then of course there is the "Armed Forces Bear" that vaguely resembles General Norman Schwartzkopf.
It's interesting how toys reflect our current culture and the state of civilization. As product of the '60s, I enjoyed a kit that taught you to grow your own sprouts. Now in this environmentally conscientious era, one can purchase a kit for recycling old newspaper into notepaper and envelopes.
Another environmental offering is an "Earth Book" which "cheerfully illustrates" how to check detergent phosphate levels and test water for oil pollution. Or you can get the science kit and learn how to contain an oil spill and study the effects of acid rain on plants. What fun.
The photo of the science kit shows two plant containers. The one on the right, next to the "normal water" packets, holds a thriving green plant. The container on the left, with the "acid rain" packets propped against it, has a browned stub of a plant poking from the dirt. Wicked stuff. Maybe we should all send science kits to our favorite legislators for Christmas this year.
The toy I like most is the pretend tool kit. I can envision hours of fun teaching Catherine to replace a leaking wax seal on a toilet, or helping Annie build a bed frame when she outgrows her crib. Better yet, if I can interest them in woodworking, they can just build their own toys. Then I won't need to look at Christmas catalogs at all. I'll just go to the nearest lumber store and stock up on wood, nails, and glue. It may be a little harder to gift wrap, but I'm willing to try.
I'm beginning to see why the Christmas catalogs appear so early. It takes about four months to decipher all the new trends in toys. I can also see why a lot of people wait until December 24th to do their shopping. It's just too darn tiresome to deal with until you absolutely have to.
Now picture me going into the kitchen to make myself that tall, cool glass of iced tea… Christmas can wait.
These articles are like time capsules. Norman Schwartzkopf? Urkel? "Stormin' Norman" is retired now and lives in Tampa, Florida. Jaleel White, who played "Urkel" in a '90s television series, is more recently known for his TV appearances in the 14th season of Dancing with the Stars. Rumor has it he got into a big fight with his professional dancing partner, Kim, but that has absolutely nothing to do with me or depression, so I'll just leave that one alone.

If the current forecasts for an El Niño weather pattern prove true, cattle will have cold, wet conditions to contend with this winter.
There is a decent chance, says Brian Bledsoe, that an El Niño will grace the U.S. with its presence this winter. "But to be honest, we're undecided what type of El Niño this is going to be," he says.
Where the warm water appears in the equatorial Pacific will determine the relative strength of the El Niño, adds the climatologist, meteorologist and ag weather consultant from Southeast Colorado. Most bets at the moment are for a weak El Niño rather than a more traditional version.
But here's the good news: for the southern tier of states, and particularly the Southern Plains, Oklahoma and eastward, Bledsoe thinks the prospects for a cooler and wetter-than-normal winter are decent.
While that's good news for cattle producers, it could mean tougher conditions for your cows, says Ted McCollum, Texas AgriLife Extension Service beef specialist in Amarillo. "When we start thinking about cows and nutrient requirements, cold, wet weather increases their nutrient requirements and may increase the focus we've got to have on nutrition," he says.
"So we may be set up this fall and winter where our cows have higher energy requirements and our forage may not be as good" because fall and winter rainfall has washed out some of the nutrients from dry, standing forage, he says. That's important because the nutrition, or lack thereof, that your cows get this fall and winter will affect the 2016 calf crop.
"We're trying to keep condition on these cows so they rebreed next spring. We're talking two years down the road where we have a major impact" with what you do this winter nutritionally.
That means producers would do well to focus on how much condition they put on their cows as fall moves to winter.
McCollum says the target for a good breed-up is for cows to calve in a body condition score of 5 or better next spring. "That's going to ensure the shortest post-partum interval to have those cows ready to breed earlier," he says.
However, nobody can pencil out exactly how much more feed you'll need, McCollum adds. That, he says, is where the eye of the master comes into play.
But there are some numbers you can go by. "We're talking averages, but if a cow has a good winter hair coat and she's dry, she's comfortable down to about a 20° wind chill," he says. McCollum defines "comfortable" as meaning that the cow doesn't have to burn energy to maintain her body temperature.
McCollum uses a "degree of coldness" measure. If the temperature threshold for a cow with a wet hair coat is a 50° wind chill, every degree below that threshold increases maintenance requirements by 1%-2%, he says. So if that cow is comfortable at 50° wind chill but it's 35° wind chill, her maintenance requirements are 15%-30% higher than on a day when she wasn't wet.
So, McCollum asks, what are your options? You can listen to the weatherman every night and feed more the next morning if things are going to get worse. Or you can play catch-up.
"If it's been cold and wet, feed more because things have happened and it's set her back a little bit," he says. That's where body condition comes into play—if a cow has adequate body condition, she has the reserves to stay warm when the weather gets bad. The extra groceries later will help her keep that body condition where it needs to be.


Product information "Nitrate/Nitrite Colorimetric Assay Kit"
The Cayman Chemical Nitrate/Nitrite Assay Kit provides an accurate and convenient method for measurement of total nitrate/nitrite concentration in a simple two-step process. The first step is the conversion of nitrate to nitrite utilizing nitrate reductase. The second step is the addition of the Griess Reagents which convert nitrite into a deep purple azo compound. Photometric measurement of the absorbance due to this azo chromophore accurately determines nitrite concentration. This kit can be used to measure nitrate and nitrite in plasma/serum, urine, tissue culture media, and tissue homogenates. However, it cannot be used to analyze nitrate and nitrite from an in vitro assay of nitric oxide synthase (NOS) in which excess NADPH has been added. For these assays a second method (LDH method) is utilized and is available from Cayman Chemical in a 96 well plate format (Cay-760871).

Q: Would an infinitely (or very long) diffraction grating produce a diffraction pattern? Take a typical science lab diffraction grating which is producing a pattern on a screen.
Let's consider the location of say the first maximum on the right side.
Let's draw straight lines from the slits to the first maximum and think in terms of ''rays'' travelling from the slits to the maximum on the screen.
These rays all converge at the maximum and although they are close to being parallel we know that they are not perfectly parallel (because they converge).
Therefore the differences between the distances that neighboring rays have to travel will not be exactly the same.
i.e. If one ray has to travel one lambda more than its neighboring ray, then the following ray will have to travel slightly more or less than its neighboring ray.
If there are many slits very close together I can see that if the variance is small compared to the wavelength then we can ignore these differences and assume that each ray travels exactly one wavelength more/less than its neighboring ray.
But if the grating is long enough, these differences will eventually build up until they are significant enough to cause destructive interference.
My understanding is that a very long grating will have destructive interference at all locations and will not produce a pattern.
Is this true ?
What are peoples thoughts on this ?

A:
Would a very long diffraction grating produce a diffraction pattern?

Yes. You might need to set the screen further back to ensure that the far-field condition is still satisfied, but given that the screen is sufficiently far away (for the length of the grating), arbitrarily large gratings can be used.
(Alternatively, you can drop the idealized introductory-textbook configuration and use a realistic design, which includes things like a curved screen and focusing optics before the grating.)

Would an infinitely long diffraction grating produce a diffraction pattern?

This is equivalent to asking "can one get infinitely far away from an infinitely long grating?". This kind of ill-defined double limit is not worth considering.

A: All secondary peaks of the pattern are going to become dimmer and dimmer until they disappear completely as the number of slits is increased. But the central peak will become more and more bright and sharp, since light from each slit interferes constructively at the center of the pattern

La centrale hydroélectrique d'Edolo est une centrale hydroélectrique de pompage italienne, sur le territoire de la commune d'Edolo, juste en aval de la ville, dans la Province de Brescia en Lombardie.

La centrale turbine, pendant les heures de pointe, les eaux de ses réservoirs supérieurs : les lacs Avio et Benedetto, et pompe, pendant les heures creuses, les eaux du réservoir inférieur à Edolo, pour les stocker dans les réservoirs supérieurs. Avec une puissance de , l'usine forme le  puissant ensemble hydroélectrique italien (après la centrale d'Entracque et la centrale de Roncovalgrande), correspondant à 5,5 % de la puissance du parc hydraulique italien. Elle appartient à ENEL.

Historique
Le lac Avio a été aménagé en 1929 et le Lac Benedetto en 1940.

Les groupes de la centrale ont été mis en service entre  et  ; ils ont été fabriqués par Voith Hydro.

Caractéristiques techniques des barrages

Le réservoir inférieur est situé à Edolo sur la rive nord de l'Oglio. Il a été créé par une digue circulaire et emmagasine l'eau pour le pompage. Sur la contenance de ce réservoir (1,4 million de m³), 1,279 million de m3 peuvent être utilisés pour le pompage. Son altitude est de 655 m.

Le réservoir supérieur, le Lac Avio, est situé à 10 km à l'est d'Edolo dans la montagne à . Directement au-dessus du Lac Avio se trouve le Lac Benedetto qui complète le lac Avio. les barrages des deux lacs sont des barrages poids hauts de 37,5 m et de 31 m respectivement. La capacité totale de stockage du réservoir supérieur (incluant le Lac Benedetto) est de 21,24 millions de m³ dont 17,04 m³ peuvent être utilisés pour la production d'électricité. L'altitude du lac Avio est de  et celle du lac Benedetto de  ; il recueille l'eau d'un bassin versant de 49,5 km².

Conduite forcée
Plusieurs tunnels et conduites relient les réservoirs supérieur et inférieur. Partant de la prise d'eau du Lac Avio, un tunnel de dérivation en pression de  m de long  transfère l'eau vers l'est puis bifurque en deux conduites forcées de 2192 m et 2203 m de long, qui à leur arrivée dans la centrale se subdivisent à nouveau pour alimenter en eau les huit groupes de pompage-turbinage.

Le réservoir inférieur est relié à la centrale par deux tunnels de  de long.

La différence d'altitude entre les deux réservoirs offre une hauteur de chute de . Le débit de turbinage est de .

Centrale électrique
Dans la centrale, chacun des turbine Francis réversibles a une puissance de 125 MW pour la production d'électricité et 140 MW pour le pompage. Seuls sept de ces groupes peuvent fonctionner simultanément.

Transfert d'énergie par pompage
Lorsque la demande d'électricité est faible et son prix bas, la centrale pompe de l'eau du réservoir inférieur pour remplir le réservoir supérieur. Pendant les heures de forte demande, cette eau du Lac Avio/Benedetto, devenue de l'énergie stockée, est renvoyée par les mêmes tunnels et conduites à la centrale pour être turbinées par les 8 turbines Francis. Après son utilisation pour la production, cette eau est reversée dans le réservoir inférieur.

Des ressources en eau additionnelles sont par ailleurs apportées par la rivière Oglio. Ce processus se répète ad libitum et permet à la centrale de servir de centrale de pointe. Cette utilisation de la faculté de stockage des réservoirs hydrauliques est précieuse pour compenser les variations de la demande d'électricité et les aléas divers de la production (pannes, fluctuations du vent et de l'ensoleillement, etc).

La centrale produit en moyenne 737 GWh par an mais consomme 1021 GWh pour le pompage. Bien qu'elle consomme plus d'énergie qu'elle n'en produise, le pompage est effectué durant les heures de nuit et les périodes non ouvrées, où le prix de l'électricité est bas. Ceci rend la centrale rentable car elle produit de l'électricité durant les heures de forte demande, où le prix de l'électricité est beaucoup plus élevé. La taille du bassin versant du lac Avio lui permet de collecter de l'eau supplémentaire naturellement : 219 GWh peuvent être produits annuellement en moyenne grâce à cette eau.

Damon "Snacks" Harrison returned to the field with the Giants for mandatory minicamp on Tuesday and said he likes what he sees so far out of the new-look defense as well as rookie running back Saquon Barkley.
In fact, Harrison cannot wait until the pads get on so he can welcome the No. 2 draft pick to the NFL.
Harrison, however, was in no mood to discuss his earlier absence from the team after he missed some of the Giants' voluntary Organized Team Activities.
"I was minding my damn business," he said when asked for a reason why he wasn't in attendance.
Harrison, 29, participated in a few of the OTAs and was in communication with head coach Pat Shurmur for the ones he missed, per Shurmur, but it was never disclosed why that was the case.
Harrison also did not attend the voluntary minicamp in April, but that was because he was finishing his degree at William Penn University.
Eli Manning offered a collective sigh of relief on Tuesday when asked about the memorabilia fraud lawsuit filed against him and the Giants that was settled last month.
"I'm just glad it's over," he said.
Manning, 37, and the Giants were accused of selling bogus "game-worn" equipment to memorabilia collectors, and were preparing to go to trial in a civil lawsuit before the two sides struck a deal for an undisclosed amount of money.
Manning and the Giants had denied any wrongdoing throughout the process.
Giants defensive back Curtis Riley continued to take advantage of his first-team reps at Tuesday's minicamp and made a play to break up a fade pass intended for Evan Engram during two-point conversion drills at the end of the practice.
The third-year corner, who was with the Titans the last two seasons, seems to be fitting in well with James Bettcher's defense.
WR Cody Latimer continued to show his knack for dropping passes, although holding was called on corner Eli Apple after Tuesday's incompletion...QB Davis Webb missed an open WR Roger Lewis on a deep ball in team drills but came back the next play to hit Travis Rudolph on a slant...The Giants signed TE Scott Simonson on Tuesday. Simonson, 25, has played in 18 games with the Raiders and Panthers over the last four seasons and spent last year on the injured reserve with a back injury.

Texas Sues EPA Over Provision of Federal Water Law
Neena Satija — August 6, 2020 0 comment
For the 20th time since the Obama administration took office in 2009, the federal Environmental Protection Agency is facing a lawsuit from Texas.
Joined by Louisiana and Mississippi, Texas is challenging the "Waters of the U.S." rule, which the EPA finalized Monday. That rule is aimed at better defining the scope of bodies of water protected under the Clean Water Act. Members of the farm lobby and Republican leaders say the rule will lead to more regulation and a takeover of private property.
In a statement, Attorney General Ken Paxton called the rule "so broad and open to interpretation that everything from ditches and dry creek beds, to gullies, to isolated ponds formed after a big rain could be considered a 'water of the United States.'"
The EPA has claimed it does not plan to expand the waters under its jurisdiction, only to clarify what they are.
"The very structure of the Constitution, and therefore liberty itself, is threatened when administrative agencies attempt to assert independent sovereignty and lawmaking authority that is superior to the states, Congress, and the courts," the states' lawsuit reads.
Paxton filed this latest challenge on the heels of the state's first win against the EPA at the Supreme Court level. On Monday morning, the justices announced a 5-4 decision striking down mercury pollution limits for power plants. The majority said the EPA hadn't properly considered costs when introducing new limits on mercury pollution from power plants.
Environmental groups in Texas reacted to Paxton's lawsuit announcement with dismay.
"It's outrageous Attorney General Paxton wants to turn back the clock and allow polluters to spoil the streams which feed great waterways like the Colorado River and Galveston Bay," said Luke Metzger, director of Environment Texas. "The EPA rule will protect 143,000 miles of Texas streams, including those which feed the drinking water sources for 11.5 million Texans.
The lawsuit is one of more than 30 that Texas has filed against the Obama administration. Paxton said earlier this year that he expects to sue the EPA again when the agency announces new rules to combat climate change in the coming months.
"Texas Sues EPA Over Provision of Federal Water Law" was first published at THE TEXAS TRIBUNE AND REVEAL by The Texas Tribune. The Texas Tribune is proud to celebrate 10 years of exceptional journalism for an exceptional state.

RSL Poll: Who gets the credit for 2013 success?
As the Red Sox remarkable season winds down and the playoff talk begins, let's take a moment to deal out some credit.
General manager Ben Cherington spent wisely and was able to put together a team capable of ignoring the chicken and beer and concentrate on winning.
Manager John Farrell proved the man for the job and a worthy successor to his former boss, Terry Francona. Will the student meet the teacher in the playoffs?
This TEAM of players grew the beards, built walk-off city, kept Boston strong through some trying times and returned the Red Sox to the top of the American League.
And we all know, somewhere in the bowels of Sacred Heart University, Bobby Valentine is figuring out a way to take some credit for this amazing season.
So often we Red Sox fans are quick to lay the blame, so why not all hold hands, don our Yaz jersey's, sing "Tessie" and give the Sox their kudos.
Who gets the credit for the Sox success?

Any rebuilt salvage title from Ohio has to be treated with great caution from the years 2009 to 2010. Repairs may not have been made and that could be potentially life threatening if safety repairs, as mandated by Ohio state law, were not completed.
According to a report in the Columbus (Ohio) Dispatch, a deputy clerk was fired after being accused of issuing sellable titles for junked autos without the required inspections and state police inspectors found numerous instances notarized title applications had blank spots, which means they were ripe for fraud.
Another flaw with salvage vehicles in Ohio is how a vehicle is determined to be salvaged. The Ohio laws are kind of murky. They merely say a vehicle is considered salvage when it's not economically feasible to repair the vehicle to its prior condition.
Lisa M. Haywood, a Pickerington, Ohio, attorney, offers good advice on Ohio law. She explains the concepts of repairable vs. total loss, which she says is 80% of a vehicle's value.
Repairable: A vehicle is repairable when the cost to fix the vehicle is less that the vehicle's value. The object of any repair is to restore your vehicle to the same condition it was immediately before the accident. To determine whether your vehicle is fixable, have it examined by at least two repair shops.
Total Loss: Your vehicle will be considered a total loss when it appears less expensive for the insurance company to replace it over repairing it. Everything is based on the vehicle's actual cash value. If the repair costs is 80% or more of your vehicle's value, the insurance company will usually consider your vehicle a total loss.
Most likely, your insurance company is going to find the lowest possible value for your car to make it easier to declare it a total loss. Ask your adjuster how the company determines the value and demonstrate any recent repairs or bodywork you may have had done recently that would increase the value. Plus, once a month, if you have a digital camera, it never hurts to snap some pictures of your used car as an informal record of its condition.
By the way, just because an insurance company considers your vehicle to be salvage, doesn't mean you can't keep your vehicle. Under Ohio law, you can but your insurance company is not going to pay you until you get the salvage title. If you decide to keep the car, you have to do the work. The insurance company does it for you when it is taking possession of your car to sell it to a scrap yard for its parts value.
Motor vehicle registrations in Ohio are administered by the Bureau of Motor Vehicles in the Ohio Department of Public Safety. Used car owners wanting to have vehicles with salvage titles branded as "rebuilt salvage titles" must first get an inspection from the Ohio Department of Public Safety.
To schedule an appointment, you need to contact the Ohio State Highway Patrol. This link will help you find an inspection office near you.
The Ohio State Highway Patrol [get ready for the legalese] "inspects the vehicle, including establishing proof of ownership and an inspection of the motor number and vehicle identification number of the motor vehicle and of documentation or receipts for the materials used in restoration by the owner of the motor vehicle being inspected, which documentation or receipts shall be presented at the time of inspection."
A fee of $50 is charged by the state highway patrol for each inspection. So, get those repairs done right the first time.
You can't operate a vehicle on Ohio highways that has been marked salvage title, unless you are bringing it in for inspection.
Ohio salvage title in the name of the person applying for title. Assigned titles and out-of-state salvage titles are not accepted.
Receipts for all replaced "major component parts" (listed below). This includes the Vehicle Identification Number (VIN) of the source vehicle.
If receipts are from a casual sale by an individual, they must be notarized.
Photocopies of receipts are not acceptable.
The inspection officer may require receipts or documentation for any part of questionable origin (ORC, Section 4505.11).
Proof of work on the listed parts below has to be provided before the rebuilt salvage title can be assigned.
Receipts may also be required for any parts with a fair market value of $100 or more. Any parts presented that are questionable or missing vehicle identification numbers are subject to seizure. This is no place for short cuts or shady deals. Use only parts that are going to pass muster—otherwise you will get caught.
The certificate of title shall be in the same form as the original certificate of title and shall bear the words "Rebuilt Salvage" in black boldface letters.
No motor vehicle the certificate of title to which has been marked "For Destruction" and surrendered to a clerk of a court of common pleas shall be used for anything except parts and scrap metal. Never buy a vehicle with this type of title with the hopes of restoring it.

I've just bought a Hyperstrada abs the previous owner put on a bigger touring screen. It's great but it is pretty big. I'm thinking about finding a screen from the hypermotard, and changing it over. I can change back if I'm doing any touring.
It's easy, just the screws you see at the bottom of the windshield. Order a new stock screen from Ducati or find one in the classifieds on here.
It's super easy. 4 screws and you're done. I have 3 screens- all Ducati. I have the touring, the stock, and the carbon fiber. I like the stock screen the least- it creates an annoying buffeting. That will probably vary depending on your height and gear. The touring goes on when the weather gets cold or if I'm traveling far. Otherwise it's the CF, which looks the best and gives a smooth airflow.
If you are looking at screens you might see some listed with a bracket- that's for the Hypermotard, which has no screen. You won't need the bracket, just the screen.

4 screw/bolts. There are many companies making some inexpensive carbon shields(~$75-100) and ofcourse the expensive ducati carbon shield. I made one using my old touring screen. It was my first ever 100% carbon fiber project. Not perfect but I'm happy for my first piece. They are getting better with time.


I don't meditate as much as I should, but I do meditate weekly, so I asked our audiologist to comment on Sam Harris's advice about tinnitus and mindful meditation.
She pointed out that most people know meditation can help tinnitus, but that's putting the cart before the horse. In order for meditation to help anyone suffering from tinnitus, or any other issues for that matter, you first need to know how to meditate with tinnitus.
Note: Below we are paraphrasing much of what Sam Harris said in his AMA #12 podcast (which you can listen to here), as well as combining advice from our audiologist.
This is difficult, because I don't want to understate how terrible tinnitus can be. But when it comes to meditation, it's not a problem in the sense that one can't have equanimity around the sound; it is just a sound.
So whatever your tinnitus is, however loud it is, you can just surrender and listen to it. And if you notice the reaction to it getting kindled, whether it's resistance or fear or annoyance you need to become mindful of that and let that dissipate.
Keep dropping back to merely being aware of it.
If you find that your tinnitus is becoming a real focus and seems to be getting louder by virtue of you meditating rather than you just noticing it more, I would recommend that you add some ambient noise.
You can meditate outside where there are many other things to listen to.
If you're anything like me, sounds do help mask tinnitus while meditating, but random sounds can actually be distracting. You don't always know when a bird is going to chirp or when the wind is going to pick up and scrape a few leaves across the ground.
In this case, you may try to play some music.
It could be music without vocals or it could be music where the vocals are in another language. I wouldn't use music where you're actually aware of the meaning of the lyrics or processing that meaning.
It can be a problem, but again sound (in general) shouldn't be viewed as a distraction.
The popular book, The Obstacle Is The Way by Ryan Holiday also mirrors this take on tinnitus, or any struggle.
Sounds can be a totally appropriate, in fact, and especially good object of meditation.

Q: Calculating area of pixels in continuous raster using ArcGIS Desktop? I have a raster with continuous values between 0 and 1.
I want to calculate the area (can be a number of pixels too) in this raster which has values in the specific range - say between 0.1 and 0.2 and 0.3-0.4.
In other words, the goal is to see which interval occupies the larger area.
What tool could be used for that?

A: You can do the counting by

*

*using the ReClassify function in Raster Calculator to re-classify your raster into an integer raster in which pixel values in your ranges [0.1, 0.2), [0.3, 0.4) ... are mapped to new integer values, e.g. 1, 2, ...,

*building a Value/Raster Attribute Tables (VAT/RAT) for the new integer raster. In the VAT, there should be a COUNT field telling you the number of 1-pixels, 2-pixels etc., which correspond to the number of pixels whose value are in your ranges [0.1, 0.2), [0.3, 0.4) etc., respectively.

A: Without creating new raster (reclassify) You can change raster symbology with given intervals. Then you can just read how many cells are in each class.

A: Why not just calculate the area directly in the attribute table?

*

*Use the raster calculator to isolate the range of values you're interested in

*Convert your raster to polygon

*Use the dissolve tool to create one feature

*Create a new column in the attribute table titled "area", and then use calculate geometry.

A: This is an old post/question but still seems relevant. If I understand the question correctly, this can be easily done using the Cell Statistics tool within the Imagery Analyst tool set.
out_raster = arcpy.ia.CellStatistics("NameOfyourInputRaster", "SUM", "DATA", "SINGLE_BAND", 90, "AUTO_DETECT"); out_raster.save(r"C:\Users\PathtoYourOutput.gdb\NameOfyourOutputRaster")


On a 45 mil roof membrane, how much waterproofing protection do you think you get?
Wait, you mean it's not 45 mils?
First it needs to be determined whether the membrane was "laminated" or "saturated." Common among single-ply systems, a membrane consists of a bottom layer, a polyester matting or scrim in the middle, and then another layer on top, which are all laminated together by a machine in a factory, to make a single sheet.
When the membrane is laminated, the top waterproofing layer above the scrim (or middle polyester layer) becomes very important.
What does this mean? NRCA studies tell us that single-ply roofs wear an average of 1-2 mils per year. So if you only have 15 mils above the scrim, you can expect the top waterproofing to be worn halfway – or more – to the scrim in just 10 years.
It's our position that once you get to the scrim you're in failure mode. You're much more vulnerable to leaks because at that point, you've lost most of the waterproofing protection.
Laminated sheets are prone to peeling, and one puncture through the top sheet can compromise that section of roof because it exposes the scrim. With a saturation technique, you have the same, continuous consistency of waterproofing throughout the entire membrane.
Metaphorically, consider lamination as a pressed wood desk with a protective sheet as the top layer; while saturation is more like a solid wood that, even when chipped or scratched, still maintains its strength and integrity all the way through.
When we're restoring roofs we're essentially manufacturing a custom membrane directly to the surface of the existing roof. Our 10-year system, for instance, starts with a base layer of liquid Wite Brite™. From there, polyester matting is rolled right into the Wite Brite™ waterproofing while it's still wet, thus saturating into the scrim from the bottom. Next, we apply two additional layers of Wite Brite™ above the scrim, each one saturating down from the top.
In the end, we'll have a fully saturated system that offers reinforced waterproofing protection without thin layers. Even further, the system is installed above the existing roof, allowing you to maintain any remaining useful life that's left in the existing roof.
Not only does a saturated membrane enable all its mils of waterproofing to truly and practically work for you, but internal tests have documented a wear rate that's much slower than NRCA's data on TPO membrane wearing.
For more information about saturated membranes, visit roof replacement alternatives.


NOTE: The term SQL can be confusing. The S, for Structured, and the L, for Language, are straightforward enough, but the Q is a little misleading. Q, of course, stands for "Query," which--if taken literally--would restrict you to asking the database questions. But SQL does much more than ask questions. With SQL you can also create tables, add data, delete data, splice data together, trigger actions based on changes to the database, and store your queries within your program or database.
Unfortunately, there is no good substitute for Query. Obviously, Structured Add Modify Delete Join Store Trigger and Query Language (SAMDJSTQL) is a bit cumbersome. In the interest of harmony, we will stay with SQL. However, you now know that its function is bigger than its name.
The most commonly used statement in SQL is the SELECT statement (see Day 2, "Introduction to the Query: The SELECT Statement"), which retrieves data from the database and returns the data to the user. The EMPLOYEE table example illustrates a typical example of a SELECT statement situation. In addition to the SELECT statement, SQL provides statements for creating new databases, tables, fields, and indexes, as well as statements for inserting and deleting records. ANSI SQL also recommends a core group of data manipulation functions. As you will find out, many database systems also have tools for ensuring data integrity and enforcing security (see Day 11, "Controlling Transactions") that enable programmers to stop the execution of a group of commands if a certain condition occurs.
This section introduces some of the more popular implementations of SQL, each of which has its own strengths and weaknesses. Where some implementations of SQL have been developed for PC use and easy user interactivity, others have been developed to accommodate very large databases (VLDB). This sections introduces selected key features of some implementations.
NOTE:In addition to serving as an SQL reference, this book also contains many practical software development examples. SQL is useful only when it solves your real-world problems, which occur inside your code.
We use Microsoft Access, a PC-based DBMS, to illustrate some of the examples in this text. Access is very easy to use. You can use GUI tools or manually enter your SQL statements.
We use Personal Oracle7, which represents the larger corporate database world, to demonstrate command-line SQL and database management techniques. (These techniques are important because the days of the standalone machine are drawing to an end, as are the days when knowing one database or one operating system was enough.) In command-line R�l, simple stand+[cedilla]one SQL statements are entered into Oracle's SQL*Plus tool. This tool then returns data to the screen for the user to see, or it performs the appropriate action on the database.
Most examples are directed toward the beginning programmer or first-time user of SQL. We begin with the simplest of SQL statements and advance to the topics of transaction management and stored procedure programming. The Oracle RDBMS is distributed with a full complement of development tools. It includes a C++ and Visual Basic language library (Oracle Objects for OLE) that can link an application to a Personal Oracle database. It also comes with graphical tools for database, user, and object administration, as well as the SQL*Loader utility, which is used to import and export data to and from Oracle.
NOTE: Personal Oracle7 is a scaled-down version of the full-blown Oracle7 server product. Personal Oracle7 allows only single-user connections (as the name implies). However, the SQL syntax used on this product is identical to that used on the larger, more expensive versions of Oracle. In addition, the tools used in Personal Oracle7 have much in common with the Oracle7 product.
* It includes nearly all the tools needed to demonstrate the topics discussed in this book.
* It is available on virtually every platform in use today and is one of the most popular RDBMS products worldwide.
* A 90-day trial copy can be downloaded from Oracle Corporation's World Wide Web server (http://www.oracle.com).
TIP:Keep in mind that nearly all the SQL code given in this book is portable to other database management systems. In cases where syntax differs greatly among different vendors' products, examples are given to illustrate these differences.
Microsoft Query is a useful query tool that comes packaged with Microsoft's Windows development tools, Visual C++, and Visual Basic. It uses the ODBC standard to communicate with underlying databases. Microsoft Query passes SQL statements to a driver, which processes the statements before passing them to a database system.
ODBC is a functional library designed to provide a common Application Programming Interface (API) to underlying database systems. It communicates with the database through a library driver, just as Windows communicates with a printer via a printer driver. Depending on the database being used, a networking driver may be required to connect to a remote database.
The unique feature of ODBC (as compared to the Oracle or Sybase libraries) is that none of its functions are database-vendor specific. For instance, you can use the same code to perform queries against a Microsoft Access table or an Informix database with little or no modification. Once again, it should be noted that most vendors add some proprietary extensions to the SQL standard, such as Microsoft's and Sybase's Transact-SQL and Oracle's PL/SQL.
You should always consult the documentation before beginning to work with a new data source. ODBC has developed into a standard adopted into many products, including Visual Basic, Visual C++, FoxPro, Borland Delphi, and PowerBuilder. As always, application developers need to weigh the benefit of using the emerging ODBC standard, which enables you to design code without regard for a specific database, versus the speed gained by using a database specific function library. In other words, using ODBC will be more portable but slower than using the Oracle7 or Sybase libraries.
Module Language-- Uses procedures within programs. These procedures can be called by the application program and can return values to the program via parameter passing.
Embedded SQL--Uses SQL statements embedded with actual program code. This method often requires the use of a precompiler to process the SQL statements. The standard defines statements for Pascal, FORTRAN, COBOL, and PL/1.
Direct Invocation--Left up to the implementor.
Before the concept of dynamic SQL evolved, embedded SQL was the most popular way to use SQL within a program. Embedded SQL, which is still used, uses static SQL--meaning that the SQL statement is compiled into the application and cannot be changed at runtime. The principle is much the same as a compiler versus an interpreter. The performance for this type of SQL is good; however, it is not flexible--and cannot always meet the needs of today's changing business environments. Dynamic SQL is discussed shortly.
This Site covers not only all these extensions but also some proprietary extensions used by RDBMS vendors. Dynamic SQL allows you to prepare the SQL statement at runtime. Although the performance for this type of SQL is not as good as that of embedded SQL, it provides the application developer (and user) with a great degree of flexibility. A call-level interface, such as ODBC or Sybase's DB-Library, is an example of dynamic SQL.
Call-level interfaces should not be a new concept to application programmers. When using ODBC, for instance, you simply fill a variable with your SQL statement and call the function to send the SQL statement to the database. Errors or results can be returned to the program through the use of other function calls designed for those purposes. Results are returned through a process known as the binding of variables.

Disney are hoping to cast Adele to play Nancy in their movie version of the stage musical Oliver! – based on Charles Dickens' classic Oliver Twist.
They have one condition though, the Grammy Award winner will have to audition, just like anyone else.
According to The Sun, Adele will not be given any special treatment, as she will have to audition for the role.
A post shared by Adele (@adele) on Apr 3, 2018 at 7:57am PDT
A source said, "Bosses are still really keen to get Adele on board. They know she has a world class voice but want to see if she can sustain that while also acting and dancing.
"It's going to be a huge production and they need to cast the right people with enough stamina. There's been a few bumps in the road on the project but everybody is quietly hopeful that once they get Adele in front of the panel they can move forward."
According to reports, Disney are also lining up Eddie Redmayne to play the iconic role of Fagin, Oliver's crooked mentor.
The production has been in the works since 2015, and will be helmed by director Toby Haynes.

Q: How can I apply black and white clipping on an image with Pillow? (Absolute image processing newbie here)
I'm trying to apply black and white clipping on an image with Pillow. To my understanding I have to adjust the contrast, my question is that is this approach correct?
from PIL import Image, ImageEnhance
image = Image.open('myimage.jpg')
contrast = ImageEnhance.Contrast(image)
contrast.enhance(2).show()

I'm trying to replicate the same functionality in a tool called Color Factory which has the options to set the "Black/White clipping" values to certain percentages.

The clipping values refer to the amount of pixels that will be clipped
outside the black and white end points. E.g. if the black clipping
value has been set to 0,5%, half a percent of the pixels in the image
will be black.

A: There are a couple of aspects to this:

*

*find percentiles

*scale values according to the percentiles

The following code should be fairly self-explanatory. It is simplest and fastest to do maths in Numpy or OpenCV. Whereas OpenCV is likely faster, I didn't want to introduce a new, large library dependency to your project when you already appear to have chosen PIL, so I used Numpy. If speed is important, just say and we can re-work it.
So, to do Photoshop-style contrast enhancement by setting black-point and white-point using percentile clipping:
#!/usr/bin/env python3

import numpy as np
from PIL import Image

# Load low-contrast image
im = Image.open('start.jpg').convert('L')
na = np.array(im)

# Check values
print(f'DEBUG: Min grey: {na.min()}, max grey: {na.max()}')

# Get low (say 1%) and high (say 95%) percentiles
loPct, hiPct = 1.0, 95.0
loVal, hiVal = np.percentile(na, [loPct, hiPct])
print(f'DEBUG: {loPct} percentile={loVal}, {hiPct} percentile={hiVal}')

# Scale image pixels from range loVal..hiVal to range 0..255
res = ((na - na.min()) * 255.0 / (na.max() - na.min())).astype(np.uint8)
Image.fromarray(res).save('result.jpg')

Initial Low Contrast Input Image

Resulting Output Image

Copyright © Mark Setchell - Red Top Mountain State Park

Debug Output
DEBUG: Min grey: 66, max grey: 187
DEBUG: 1.0 percentile=78.0, 95.0 percentile=162.00

Note that you can make a low contrast greyscale from any starting image just in Terminal with ImageMagick like this:
magick input.png -colorspace gray +level 30% low-contrast.png

A: As I was seeking for the same answer, I tried to get an understanding of black & white clipping in image processing. The following explanation and code is equally applicable for white clipping.
For black clipping you want that a certain range of dark pixels (e.g. 0 up to 10) to be actually black (value 0) instead of black-ish. When assigning 0 to all those values, there will be a gap in the histogram. To overcome this, you transform the remaining pixels values from the range [10...255] to [0...255]
My implementation for RGB images using OpenCV and python looks as follows:
def bgr_clipBlack(img, value):
"""Clips the black part of the image. Pixel values ranging [0, value] will be all
clipped to 0 in the resulting image. The image shall be in the BGR format,
value shall be between 0 and 255."""

lut = np.zeros((1, 256), np.uint8)
if value != 255:
    for i in range(value, 256):
        lut[0, i] = ((i - value) * 255) / (255 - value)

return cv2.LUT(img, lut)

img is the image read by cv2.imread().
The function clips the values of each of the channels (R, G and B) within [0...value] to 0 and transforms the remaining values from the range [value...255] to [0...255] using a look-up table.
This gave the same results for me as the corresponding Lightroom function.

A: Adding to Mark's excellent answer, a slight improvement is to scale in a linear colourspace.
The numeric value in a file like JPG or PNG is not linearly proportional to the amount of light at that point in the scene. Instead, there's a gamma applied, meaning a non-linear curve.
https://en.wikipedia.org/wiki/Gamma_correction
This is done to improve image quality. Sensors typically have a Poisson noise distribution, so by applying a curve like this, the available 8 bits of data you have are spent more on signal and less on noise.
The consequence for brightening or darkening images is that applying a linear transform to a JPG image, such as:
pixel_out = a * pixel_in + b

will tend to boost brighter areas more than it should. It's better to transform to a linear space (remove the gamma), then apply a linear scale, then reapply the gamma.
Here's a sample program (using pyvips because I'm very familiar with it):
#!/usr/bin/python3

import sys
import pyvips

def scale(image, highest):
    """Scale an image so the min value is 0 and the max is "highest"."""
    mx = image.max()
    mn = image.min()
    offset = -mn
    scale = highest / (mx - mn)
    image = (image + offset) * scale

    return image

def linear_scale(image):
    """Scale an image in linear space."""
    image = image.colourspace("scrgb")
    image = scale(image, 1.0)
    image = image.colourspace("srgb")

    return image

image = pyvips.Image.new_from_file(sys.argv[1])

print("writing non_lin.jpg ...")
non_linear = scale(image, 255.0)
non_linear.write_to_file("non_lin.jpg")

print("writing lin.jpg ...")
linear = linear_scale(image)
linear.write_to_file("lin.jpg")

"scrgb" colourspace is RGB, but using three floats for each pixel,  0 - 1 for black to white, and linear colourspace (so no gamma). pyvips knows how to apply and remove the regular image gamma for you. You would never write production code like this (you'd compute a single lookup table instead) -- this is just supposed to show the principle.
Here are three images for comparison. Mark's original on the left, non-linear in the centre, and the linear version on the right.

You can see the non-linear version (in the center) has become much too contrasty as the bright areas have been boosted too much. The version on the right (the one done in linear space) looks much more like the original.

Information published on 5 June 2012 in the UIC electronic newsletter "UIC eNews" Nr 295.
UN World Environment Day: UIC supports the UN World Environment Day "Green Economy: Does it include you?"
Release of the UIC sustainability report, "Railways and Sustainable Development – A Global Perspective"
The UN World Environment Day is taking place today under the slogan "Green Economy: Does it include you?" Through this Day, UIC would like to show our strong commitment to environmental issues, and to emphasise that rail is an essential part of the solution for sustainable development.
The growth of mobility has delivered economic growth, but has also created environmental and social challenges. This trend in car ownership and use can be seen on a global level where transport already accounts for over 50% of world fossil fuel use. This share is expected to increase to over 60% by 2035.
The majority of fossil fuel is used in the road sector; railways can help address this issue by providing lower-carbon mobility: rail has approximately a 6% share of the world transport market, but only produces 2% of transport greenhouse gas (GHG) emissions .
Today UIC releases its new sustainability report, "Railways and Sustainable Development – A Global Perspective". The brochure provides examples and case studies from many of the 50 UIC member signatories to the UIC Declaration on Sustainable Mobility, which was officially launched at the United Nations in May 2011 in the presence of UN Under-Secretary-General Mr Sha Zukang. It is the first publication in what will become a regular series of such reports, to be produced every two years.
Meeting the expectations of society
Massive investments in renewable energy including a "Solar Tunnel" in Belgium where solar panels cover a railway tunnel eight football fields in length and investments in wind farms for railways in Germany and Japan
Innovative approaches to wildlife management including "Green Bridges" for migrating animals in Poland: Bald Eagle protection schemes in the USA and Bird Nesting sites on catenary poles in Bulgaria
Meeting the expectations of customers
Massive investment programmes to improve accessibility for persons of reduced mobility, for example Indian Railways are improving accessibility at over 1,500 stations
Roll-out of WiFi internet access on many rail services including for example the Acela Express service on the North East corridor of the United States
Governance and responsibility
Being stable and attractive employers – Chinese and Indian Railways are two of the largest employers in the world with 2 million and 1.65 million staff respectively
Efforts to attract a more diverse workforce including the French "Equal Opportunity Train" which has toured the county four times promoting careers in rail in less advantaged areas

LOS ANGELES (AP) — Matthew McConaughey, Mila Kunis, Jennifer Hudson and "Abbott Elementary" creator and star Quinta Brunson have been named People magazine's 2022 "People of the Year."
The magazine unveiled its annual list Wednesday, with Editor in Chief Wendy Naugle explaining this year's honorees were selected because of their efforts to help others.
McConaughey was chosen for his advocacy efforts after the Uvalde school shooting rocked his hometown. Kunis was lauded for her fundraising — which People said has topped $37 million — for Ukraine, where she was born.
Hudson and Brunson were honored for their onscreen work. Hudson, who launched a daytime talk show this year, was cited for her efforts to create an inclusive show where everyone felt welcome. Brunson's "Abbott Elementary," a critical hit that turned her into an Emmy winner, was praised as a show that brought many joy and showed that different generations can work well together.
Each of the honorees are featured on a special cover that highlights their contributions. Kunis' includes the quote, "I'm proud to be from Ukraine," while Brunson includes her statement: "I'm a sign that times are changing."
McConaughey's proclaims, "We have to do better for our kids," while Hudson's says, "I'm living my dream — and learning as I go."
Previous People honorees have included George Clooney, Regina King, Dr. Anthony Fauci, Sandra Oh, Selena Gomez and Simone Biles. This year's special editions will be released Friday.

RE-POST: Mineral make up, what's it all about and do we really need to use it?
Make up is such a wonderful thing, I hear some women complain about it being another thing forced upon us by the patriarchy, but I feel lucky that when I'm hungover and looking like death, it's socially acceptable for me to stick on concealer or mascara and look half human again!
I spend a lot of time, effort and money on my skin, so isn't it reversing this hard work when I wear make-up?
I will admit when I was younger I was a serial user of dream matte mouse from Maybelline and I would cake it on my face, I have freckles and used to hate them so much that I would wear an inch of make up to try to hide them. I certainly don't do that anymore, but I do like to have some coverage and a matte look. When I became an Aesthetician, I started to consider the make-up I used, this is where I first came across mineral make up.
What is mineral make up?
True mineral make-up is made up completely of minerals mined from the earth such as zinc oxide, iron oxide & titanium oxide. They are ground into very fine particles which are then used to make products such as powder and foundations, because of their natural content they do not contain oil or wax which can be found in normal make up. Ingredients can even help to soothe and heal the skin, have sun protecting benefits and are suitable for all skin types (including sensitive) while giving great coverage!
Are all mineral make ups the same?
No is the simple answer. When I started with mineral make up I began with the well know high street brand bare minerals original powder. I found I liked the feel and look of it on my skin, however knowing what I know about skincare (high street brands are not always what they seem) I thought I'd do some research into this product.
I found a great article on Bismuth Oxychloride. It is a mineral within bare minerals but not a natural one, it's obtained as a by product of lead or copper smelting. It's used to give powders a shimmering effect and can be irritating triggering rashes & acne breakouts!
Don't always believe the high street hype, as per usual products that are sold in professional atmospheres like aesthetic clinics are going to be the most clinically tested and best choice in my opinion.
Some brands I've worked with in clinic are lycogel & oxygenetix. They both give high coverage but are breathable and great for healing the skin. They are popular brands within clinics as they can be applied straight after treatments such as medical needling to give coverage without the risk of damaging the skin when it's so delicate.
As a day to day make up they're too thick for me, but for people that suffer with severe pigmentation or a lot of redness, this is a great option for coverage while still having a healing and sun protecting benefit.
I really rate Jane Iredale also known as 'the skincare make-up' as it truly is only mineral make-up. It's a good coverage but very light weight and blends to my skin tone perfectly. They also do beautiful lipsticks, eye shadow pallets and highlighters/blushers. One of my favourite products is the under-eye circle delete concealer, it covers dark circles without sitting in lines and making me look way older than I am!
You will find this brand in a lot of aesthetic clinics as it is 100% natural mineral make up. It has an SPF of around 20 in it as well, but I would never substitute this for a sunscreen, use this as well as sunscreen!
I use Jane Iredale when I'm going out as the liquid foundation gives me more coverage (as seen above).
I am currently using colorescience, I was lucky enough to have been given a sample at an event I was working at and OMG I LOVE IT! The loose mineral foundation is brilliant to take around and top up on the go as it has an SPF in it. It was so convenient to use on holiday to keep my skin matte but also protected. The corrector palette is also brilliant at covering any odd break outs that I get or if my dark circles are looking particularly bad after 1 too many late nights then this makes all the difference.
It uses only pure, natural ingredients, 100% chemical free, a physical SPF, water and sweat resistant for 80 minutes and contains antioxidants to protect the skin from free radical damage.
My skin looks totally matte but when I have it on nobody can tell, so this is my top pick when it comes to a mineral make up.
Powders start from around £40 depending on which product you go for but (I would recommend loose mineral powder).
Most clinics will not charge you to go in a have a colour match so it's well worth going in to try the products out on your skin to see if you like the feel and look of them. Remember to read the label and that high street brands may not be all they seem.

With the development of engineering systems and information technology, our daily and business life have become inconceivable without a use of a wide range of engineering services. All of them, starting with conventional water and sewerage systems to modern low-current networks make our lives more comfortable. But on the other hand, they clutter up the space, lead to inefficient use of the area and spoil an appearance of the premises.
Installation of the raised floor is the only effective solution to this problem. Lifted above the ground, it creates additional space in which it is possible to conceal absolutely any kind of communication (for example, a pipeline, heating systems, network cables).
The main elements in the raised floors design are special panels. They can be made from different materials. As a rule, the most popular panels used in the office fit-out are made from high density chipboard with the steel covering; for the server rooms it's often sulfate calcium panels reinforced with the fiber.
Assuming a role of the raised floor surface, panels are laid on pre-installed supporting pedestals. In general, the technology of the raised floor installation consists of four main stages. They are pedestals installation, fastening them with stringers, setting of the panels and the final adjustment of a height and a flatness of the finished system.
After that modular floor coverings are placed - usually it is a carpet or a linoleum tile. This is necessary to preserve the possibility of rapid disassembly and reassembly of any single area of the raised floor.
For convenient use of power and low-voltage outlets, the raised floor is equipped with a special floor hatches, embedded in its panels. The hatch cover has a recess-pocket for inserting a piece of carpeting or other floor coverings, which is laid in the room, so the whole floor looks uniformly.
Practicality. An installation of a raised floor allows us not only to conceal all communications but also provides convenient access to them. If necessary, this construction is easily disassemble and re-assemble again.
Reasonable price. The raised floor can be placed on the base of any type. Mostly, it's concrete screed. Moreover, even if the surface has defects and irregularities, they could be easily eliminated by changing the height of adjustable pedestals, on which the raised floor is installed.
Aesthetics. Installation of raised floor requires further stacking of the modular flooring. Thus, the appearance of the floor will be as you desire it to be. In addition, the raised floor design eliminates a need for the cable channels, drywall boxes and other devices that hide the cabling in the room.
High speed mounting. Installation of raised floor does not require complicated preparation works or "wet" processes involving water, which greatly facilitates and accelerates the process.
Safety. A covering used for raised floors have excellent sound insulation, antistatic and flame resistant characteristics. This, in turn, leads to a complete operational safety of this design.
Subsequent carpet installation or laying linoleum of a tile type.
Prompt installation – up to 100 square meters per day.
The cost of raised floor installation is calculated based on its height, squared footage, type of panels used and working environments. To discuss details of cooperation and to order the service, contact the office of LLC "Int-Ext" by phone: +7 (495) 135-0-777.


A well-crafted rental advertisement will help cultivate plenty of quality responses. The overall secret is to feature the best aspects of your rental space and include pertinent descriptive information in your ad.
Include details that aren't seen in the property description, but don't exaggerate. In Tip #14, I discuss the importance of accurately describing a property.
Always include the Price. Surprisingly, ads with prices get more views than those without.
Use rich adjectives: Spacious garage, Amazing views, Private fenced-in yard.
Be specific and include appealing or unique features, such as "Viking Oven and Range." Viking is a luxury brand and will help you attract higher-end tenants.
Post as many photos as you can, but realize that every internet listing site has limits to how many photos you are allowed to upload. Always include pictures when posting to Craigslist! If you have more pictures than allowed, consider posting them to your Google+ page, and making the photos "public." For really tech-savvy landlords, I recommend shooting a quick 3-minute video tour with your phone, and uploading it directly to YouTube. Then you can link to the YouTube page from your Craigslist ad.
Pictures communicate much to a potential renter, therefore ensure the photos included are high quality and make the rental space look its best.
In a previous article, I discussed the considerations of furnishing the unit. Furnishing or staging a unit can sometimes help a tenant see past the empty rooms, and help them envision themselves living there. Regardless, the rental unit should look clean and clutter free.
Utilize natural or direct lighting.
Take pictures during the daytime or turn lamps and other direct lights on at night.
Don't use a flash – it can make the area look artificial.
When taking a picture, keep the main light source behind you – but remember not to cast a shadow.
Take pictures from the furthest corners so the room looks larger.
Taking pictures while crouching or kneeling is often a good method because it makes the ceilings look higher.
3. Make Your Rental Easy to Find!
When you create your listing, take search engine optimization (SEO) tactics into consideration to get more traffic for the listing.
The optimization process helps people quickly determine if the listing is relevant to their search.The goal for creating quality listings is to improve the content of the listing so it can pull in more visitors from search engines.
Utilize Analytical Tools: There are several free tools available that help you analyze your traffic and monitor your website performance. My favorite tool is Google Analytics.

Q: Storing values in Rails session I'm taking a course on Rails, and I need to "remember" the values selected by the user across https requests, in order to filter a list.
I am supposed to do this in the session 'Hash'.
Here is my index:
def index
    #list all different values for the key ratings
    @all_ratings = Movie.uniq.pluck(:rating)

    #order movie list based on interaction with link from view
    @movies = Movie.order(params[:sort_param])

    #filter movies by rating, based on checkbox from view
    @movies = @movies.where(:rating => params[:ratings].keys) if params[:ratings].present?

    # I intend to store here the ratings selected, and then save in session
    @selected_ratings = params[:ratings].present? ? params[:ratings] : [])

    #It gives this error: undefined local variable or method `selected_ratings'
    session[:selected_ratings] = @selected_ratings
end

Here my view:
%h1 All Movies

= form_tag movies_path, :method => :get do
  Include:
  - @all_ratings.each do |rating|
    = rating
    = check_box_tag "ratings[#{rating}]", @all_ratings, @selected_ratings.include?(rating)
  = submit_tag 'Refresh'

%table#movies
  %thead
    %tr
      %th{:class=> helper_class('title'), :id => ('title_header')}= link_to 'Movie Title', movies_path(sort_param: 'title')
      %th Rating
      %th{:class=> helper_class('release_date'), :id => 'release_date_header'}= link_to 'Release Date',movies_path(sort_param: 'release_date')
      %th More Info
  %tbody
    - @movies.each do |movie|
      %tr
        %td= movie.title
        %td= movie.rating
        %td= movie.release_date
        %td= link_to "More about #{movie.title}", movie_path(movie)

And now the questions:

*

*When I render the debug in the view, and I choose one filter (PG in this case), I get this:
--- !ruby/hash-with-ivars:ActionController::Parameters
elements:
  PG: G R PG-13 PG
ivars:
  :@permitted: false

I don't quite understand that. I guess ivars are instance variables, but I don't know why the hash is not shown in a proper {hash}, and only with the values selected.

*How do I use session[:selected_ratings] to remember the filter for the movies? I mean, how do I use session as a parameter.
Maybe:
@movies =@movies.where(:rating => session[selected_ratings].keys)

*Where can I read about how to use session, how to store, how to access and use the params stored... I have read this, and that, and also some blogposts about sessions, authentication...
But I didn't manage to understand and apply to other situations than the ones described in the blog.

A:
Why do I get the undefined variable error if selected_ratings is defined?

@selected_ratings is defined; selected_ratings is not. What you meant to do, I think, is something like:
@selected_ratings = (params[:ratings] || session[:selected_ratings] || [])
session[:selected_ratings] = @selected_ratings

Note that this is using a symbol, rather than an undefined variable.

Let's pretend session[selected_ratings] works, how do I use it to filter the movies? Maybe: @movies =@movies.where(:rating => session[selected_ratings].keys)

Well, what does @selected_ratings equal? I suspect it's probably an array of ratings, right? - Something like: ["PG", "PG-13", "R"]. In which case, ActiveRecord is clever enough and generating SQL, that you can just do something like:
@movies.where(rating: @selected_ratings)

Most importantly, where can I read about how to use session, how to store, how to access and use the params stored... I have read this, and that, and also some blogpost about sessions, authentication... But I didn't manage to understand and apply to other situation than the described in the blog.

That's a bit vague; I don't know what to suggest beyond the Rails documentation etc. for a beginners' overview. If you have a more specific question, I'd be happy to help.

A: Undefined error is because you refer to variable selected_ratings which isn't defined (you defined @selected_ratings, which isn't the same thing).
To answer your second question, you can do like so:
@movies = @movies.where(:rating => session[:selected_ratings])

session hash is easy to work with. You save and retrieve values just like you would with a regular hash.
