Phone bills show frequent calls from Mayor Sam Adams to 17-year-old
By Jerry Casey | The Oregonian/OregonLive

Interview with Willamette Week
» Timeline of Adams-Breedlove calls
Portland Mayor Sam Adams called Beau Breedlove 33 times when the younger man was 17 -- far more contact than Adams has acknowledged having with the teenager.
Adams has said that his contact with Breedlove, with whom he had a sexual relationship, was infrequent and that Breedlove pursued him.
Adams' phone records show he made most of the calls to Breedlove in the weeks after they met in March 2005. Three months later Breedlove turned 18, the age of consent in Oregon. The records don't show when Breedlove made calls to Adams.The Oregonian has recently reviewed Adams' phone bills and calendars as part of a series of requests to the city under the state's public records law.
These records and interviews show that the Adams-Breedlove relationship grew earlier than previously known. Both Adams and Breedlove declined to comment.
Adams is under an Oregon Department of Justice investigation after admitting in January that he and Breedlove -- who is 24 years younger -- had a sexual relationship and then lied about it.
On Jan. 15, Willamette Week reporter Nigel Jaquiss, editor Mark Zusman and managing editor Henry Stern interviewed Mayor Sam Adams at City Hall about his relationship with Beau Breedlove.
For more than 16 months, Adams had denied having a sexual relationship with the teenaged Breedlove. But Jaquiss had turned up new evidence.
What follows is a 38-minute recording of that interview, during which Adams lies repeatedly and evades questions about Breedlove. Four days after this interview, Adams admitted he and Breedlove did have a sexual relationship.
Willamette Week has not made the entire interview public. Adams' staff, however, made their own recording of the interview, and The Oregonian obtained it under the state's public records law.
The recording opens with Zusman speaking. Other people speaking during the interview include Adams' press spokesman at the time, Wade Nkrumah, a former reporter for The Oregonian; and Amy Ruiz, an Adams staff member who had investigated the Adams-Breedlove story while she worked as reporter for the Portland Mercury.
WARNING: This recording contains explicit language that some may find objectionable.
Timeline of calls between Sam Adams and Beau Breedlove

Other records raise new questions about Breedlove's story.
Adams has said that Breedlove had just turned 18 when the two had sex. Breedlove tells the same story. And he adds a detail: that the two kissed in a City Hall men's room after a First Thursday event June 2, 2005, when Breedlove was 17.
But Adams' calendar shows that he was in New York on vacation that week.
State criminal investigators have interviewed one person whose account suggests a different timeline for the City Hall encounter.
A former City Hall security officer told investigators that during a First Thursday event earlier in 2005, another guard reported discovering Adams and a young man in the second-floor men's room.
Glenn Clark says he told investigators that he was working City Hall's first-floor security desk while another guard, Jacoby Demissie, was stationed on the second floor. Clark was surprised when Demissie walked downstairs, stopping about 10 feet from him.
Clark recalled that Demissie told him "in a flat tone something to the effect of: 'I just saw Sam Adams having sex with this younger guy in the bathroom,'" Clark said in a statement.
"I cannot be certain of exactly what Demissie said," Clark said in the signed and notarized statement, which he gave to investigators and The Oregonian. "But the way Demissie made the statement made it clear to me that Adams and the younger man were doing more than kissing or making out."
Because Demissie mentioned that the other man was young, Clark said, Clark was concerned that the young man might be underage. Clark said Demissie told him it didn't look that way.
"I worried about the younger man's safety because it was my job to be concerned about everyone's safety in the building," Clark said. "I figured no one was in danger and did not visit the second-floor bathroom to check it out."
Clark told The Oregonian that he didn't record Demissie's report in that evening's incident log. A check of the log confirms that.
Clark's account has problems.
First, Demissie told The Oregonian that the incident never happened. Second, Breedlove described a security guard who found him and Adams in the men's room that night as an older white man. Demissie is young and African American. And the date doesn't fit Breedlove's account.
Other records suggest Clark's story is plausible.
If Adams was in New York in June, as his calendar says, Breedlove's account of the timing couldn't be right.
When he spoke to The Oregonian, Clark said the incident would have happened before mid-April when he left the contract security firm, DePaul Security. He also recalled that he worked with Demissie that night and that Demissie had shown up to work late.
A review of City Hall security logs for April 7, 2005, shows that Clark and Demissie both worked during the First Thursday event and that Demissie arrived about the time Clark remembered. This was the only First Thursday event Clark and Demissie worked together after Adams and Breedlove met.
Demissie did confirm parts of Clark's account: that he was routinely assigned to the second floor of City Hall for First Thursday events and that he used the men's room on that floor while on duty. The security log for that night also shows Demissie assigned to the second floor.
Clark has gone back to work for DePaul Security but says he hasn't worked City Hall since 2005.
Post-scandal activities
The outcome of the state Department of Justice investigation could come down to the word of Adams and Breedlove, both of whom acknowledge lying in the past about their relationship.
Breedlove, now 21, could become a problematic witness should Adams be charged. After saying he wanted to maintain his privacy, Breedlove gave a nationally televised interview, posed for a gay erotic magazine, signed autographs at an adult video store in Portland and served as a judge for a sexually explicit contest at a Portland doughnut shop.
Adams, 45, has tried to move past the controversy, working on high-profile deals such as Portland's Rose Quarter, the new Columbia River bridge and a proposed convention center hotel.
Meanwhile, the mayor's office has been distracted by the ongoing investigations by the state and the media.
The Oregonian and other news agencies flooded City Hall with records requests after Adams' admission Jan. 19. Officials have provided the newspaper access to hundreds of pages of spending records and a dozen archived boxes from Adams' years as a city commissioner.
The mayor's office also released a recording of an interview Willamette Week had with Adams four days before he admitted the truth about Breedlove. The recording shows Adams repeatedly lying and evading questions put to him by the newspaper.
What the records show
The records fill in some blanks in the Adams-Breedlove relationship.
Adams and Breedlove probably first met at the state Capitol on March 24, 2005. At the time, Breedlove worked as an intern for state Rep. Kim Thatcher, a Keizer Republican.
Adams' calendar for that date shows he had meetings with two Democratic legislators whose offices were near or next to Thatcher's office. Breedlove gave Adams his phone number through another person.
Breedlove told The Oregonian that Adams sought him out about a week later. Adams' cell phone records show that he called Thatcher's office March 31 and that the call lasted three minutes. The records show that Adams then called Breedlove's cell phone twice later that afternoon.
Adams personally gave The Oregonian his phone records and blacked out what he said were personal calls except for those to Breedlove. The billings don't show the source of incoming calls, nor do they provide a record of text messages.
Adams made most of the calls between March 31 and May 9, and many lasted just one minute.
Adams made fewer calls in May and June but kept in touch, including soon after he was scheduled to return from his New York vacation.
According to Adams' calendar, his flight home was scheduled to arrive at 8 p.m. June 4, 2005. Portland International Airport records say the plane arrived at 7:39 p.m.
Adams' phone records show the first calls he made after the flight arrived were to Breedlove's cell phone and the home of Breedlove's mother.
Adams also called Breedlove on June 25 -- the day Breedlove turned 18.

Is this still the Dragonfly Thread ?
I read on another forum that should work with one plus 3 ... But it consumes a little bit. It is supplied only with a type-c to male usb cable. You would need a y-cable, where you can connect a power bank to power the type-c of the DA3 and instead only otg from the cell phone to the DA3.
If we are to continue speaking about Sabaj though, unless it's in comparison to the DFB or DFR, we probably SHOULD start a new thread. Up to you guys.
From what I've read, the DFR is the more efficient one with less power draw.
Really?? It was a year or so ago, but the one or two I read said the opposite. Anyone know for sure?
I would think the "more powerful" one would also be the one that drew the most power, but efficiency can make a lot of difference too.
Yes, DFR is still a Marvel, but What about DFB (reminder for 99 usd)? DFB is not better than DA2 for 69 usd. Moreover, gap between DFR and the other usb dac is closing. DFR and DFB need es9018 and es9038q2m, respectively, with `hiss free design` right now, if AQ wants to sustain its business in a good way.
Yeah, I agree. Though the advancements from each new Sabre DAC & amp are minimal at best, over a couple generations, things start to add up. Better noise filtering & instrument separation, widening of the soundstage, better power efficiency, etc..............AQ needs to compete. That doesn't mean they should release a new set of DragonFly amp/DACs every year, but definitely every 2-3 years for sure. The fact that AQ doesn't appear to have any plans to release a new DF this year is not a good sign for them. The DFR and DFB are now officially 2 years old as of March (DFR) and April (DFB) of this year, so if not this year, then they are pushing into the 3 year mark. And even then they may just rely on firmware updates and think that will keep people around. But it won't. Not with devices like the ones Sabaj is making.
I'm quite happy with my DFB and find it actually drives low resistance (he400i) planars extremely well. I prefer it because it keeps my volume controls on my keyboard while gaming. I can't see myself upgrading anytime soon.
I'm pretty sure most of us (me included) could not hear the difference between the the DFR with the ES9016 and any successor using the ES9018 or ES9038 DACs. The ES9016 is already a champion in its sound qualities, and combines a nice digital volume and amp. It also consumes not a lot of battery power. However any improvements will be in the form of better power management (to diminish the power requirements and battery usage when used with tablets of phones) and additional compatibility with higher end digital formats (DSD and sampling rates over 96mhz). Note that these two grounds of improvements are conflictual, since compatibility with higher end codecs will require more power, offsetting any gains in power management. But in real world when using 16 or 24 bit 44.1khz music files (which account for 99% or so of all digital music available in this world), I don't expect any significant improvements in the sound quality of the future device taking the place of the DFR in Audioquest's offering. Just my 2 cents of comment, for what it is worth... Direct lightning (iOS) compatibility would bring a good improvement I must admit, getting rid of the use of adapters.

Interview with Silvia Pipponzi
Interviews | October 28, 2016 |
Image courtesy of Silvia Pipponzi
Luca Curci talks with the artist Silvia Pipponzi during FRAGMENTED IDENTITIES, second appointment of BORDERS festival, in Venice on August 2016. Silvia Pipponzi was born in October 1992, in a historical village in Italy, called Falerone. She started to study dance when she was 4 years old. After one year studying law at the University, she came into a breaking point where the artist had to figure out what she was going to do for the rest of her life. Suddenly, Silvia understood that she could not keep waiting for her dreams to come true without doing anything about it. She worked really hard and she graduated in Contemporary Dance at the National Dance Academy of Rome.
Luca Curci – Please, tell me about your artwork shown during our festival.
Silvia Pipponzi – It is a site specific work in which the aim is to create a performance where the landscape, the installation, and the sculpture enhances the movement. The concept digs deep into the relationship between body and architecture, showing that body is architecture in itself. It is a salient architectonic form that interplays with the dimensions of space and time. Space itself is pliable, active, and alive. Breath and air are essential to body and space, rendering a kinesthetically dynamism. The body in motion designs the space, and the space navigates the body's movement. Imagining the space full of lines that could be bent, tossed, or distorted, the aim of the performance is to visualize a geometric space composed of points that are vastly interconnected. As these points are within the dancer's body, there are not transitions, but a series of folding and unfolding that produce an infinite number of movements and positions. From a sculpture or an installation, it is possible to extend it out into space.
L.C. – We were attracted by your last artistic production, has the artworks presented been created for the festival FRAGMENTED IDENTITIES or as a part of pre-existent works? S.P. – One year ago I had a performance in a Roman cistern in which I had to relate my body with the space. From this experience I developed an idea which I applied for the "FRAGMENTED IDENTITIES". Thanks to this performance, my interest in the relationship between movement and architecture began. In the beginning it was just a curiosity, but then thanks to this festival my ideas could fully take shape.
L.C. – When did you start practicing art and why?
S.P. – I am extraordinarily blessed to do what I love for a living. Somehow in the last decade I have turned a passion into a profession, and then into a lifestyle. I started to study dance when I was 4 years old. I always wanted to be a dancer, but I never had the courage to admit it. After one year studying law at the University, I came into a breaking point where I had to figure out what I was going to do for the rest of my life. Suddenly, I understood that I could not wait for my dreams to come true without doing anything about, so I did. I knew it was the right choice. Dance for me represents an opportunity to discover new ways to compare ourselves with our own body, senses, and mind. Art is something through which we can see.
L.C. – Can you talk about your artistic work? Which are your inspirations?
S.P. – I'm a freelance dancer, currently training in Israel. My individual works usually involve the relationship between dance and the other art-forms that I love, such as architecture, literature, poetry, visual art, and theatre. I get my inspiration sharing my knowledge, my experiences, and my personal view with people that I meet during my journey. This does not only include dancers but also other artists and audiences. I will continue to keep evolving myself as an artist as well as a human being.
L.C. – What's the art tip you usually receive?
S.P. – It depends on the kind of performance, company, theatre, and town, usually about 200 €.
L.C. – Do visitors' suggestions enrich yourself and your art?
S.P. – The visitors' suggestions enrich me so much. Receiving feedback about my work is very important in order to discover my limits, challenges, qualities and weak points.
Usually, being an artist means that you have to be completely honest with your audience. You cannot lie with the movement. When I started to dance professionally, for real audiences, the fear began. It's a struggle with ourselves with the fear of not being good enough, being horrible, or being an embarrassing failure. It was this fear that inspired me to improve.
L.C. – What art themes do you pursue? What are your preferred subjects if any?
S.P. – Dance is my natural environment where I feel the most comfortable; however, I'm interested in many other subjects like architecture, drama, poetry, and visual art. Usually, when I do my own choreography I love to research human emotions and try to represent them through movements, taking the inspiration from other subjects.
L.C. – What do you think about It's LIQUID Platform?
S.P. – I think it's an amazing way to meet different kinds of artists and people. Differences create possibilities instead of building borders.
L.C. – Do you think It's LIQUID Group can represent an opportunity for artists? S.P. – I think that It's LIQUID group represents an important opportunity for artists who want to show their artistic research, and share ideas and point of views with people from all over the world. When you share, you grow.

P&G Associates - Do You Know The Security Features of the New $100 Bill?
On Course » Duplicate of OnCourse Staff » Do You Know The Security Features of the New $100 Bill?
Have you ever went to a Bank, handed the teller a $100 bill, and notice him/her carefully examining it? Have you ever had the employee at the gas station refuse to take your $100 bill? Nowadays, everyone is skeptical about receiving currency from an outside source other than a financial institution due to the circulation of counterfeit money. So, to stay ahead of and to lower counterfeit money, the government redesigned the $100 bill. The Federal Reserve supplied financial institutions with the new $100 bill on October 8, 2013. The new bill will be "easier to authenticate, however, it will be harder to replicate" with the new security features.
Do you know the security features of the new $100 bill? There are two new security features: 3-D Security Ribbon and the color changing bell in an inkwell. The Security Ribbon is woven into the bill, and it changes from bells to 100s when shifting the bill from side to side. The color changing bell in an inkwell, located on the right side of the bill, changes from copper to green.
There are other security enhancements on the $100 bills, such as the portrait watermark, security thread, color-shifting 100, raised printing, large gold 100, micro-printing, and FW indicator.
The Portrait Watermark - If you hold the bill to the light, you will see a watermark of Benjamin Franklin on the right side.
Security thread - To the left of the portrait, you will see a thread running vertical with USA and 100 imprinted on it.
Color-shifting 100 - The small 100 on the right corner of the bill changes colors from copper to green.
Raised Printing - If you move your fingers up and down on the left side of Benjamin Franklin's shoulder, the ink will feel rough. Large Gold 100: On the back of the note, there is a large gold 100 on the right side.
Micro-printing - On Benjamin Franklin's left collar, you will see small printing of The United States of America. Also, in the blank space where the portrait watermark is, you will see USA 100 around it. Around the golden quill, you can see One Hundred USA and small 100s in the note borders.
Take a few minutes to examine a new $100 bill to see if you can recognize all the security features mentioned above. If you know your currency, you will have a better chance of protecting yourself from encountering counterfeit money.

The Global Cold Chain Alliance (GCCA), a recognized authority in the cold chain industry where every product retains quality and safety, holds several conferences throughout the year for its members. Rather than having each presenter come up with their own PowerPoint that could be full of problems for attendees, they have become proactive and give their speakers a template to follow that is customized for every program.
They recently shared in PCMA's Convene the following tips that work best with presentation services audio visual equipment.
Tip #1: Simplicity is a Beautiful Thing.
A good rule of thumb is 50 words or less on a slide. However, I believe the fewer words,the better. Keep only the text on the slide that will remind the presenter what they need to cover. Reading a slide is a big "no-no".
Tip #2: Choose Legible Font Styles.
Clear, large font types, such as Arial or Tahoma, work well in most room settings. GCCA recommends a size of at least 18 points while Guy Kawasaki states the minimum should be 30. Know the room set up and make certain the person in the back of the room can view the presentation with ease.
Tip #3: Keep Fonts Consistent.
Don't start out with one font and then move to another and yet another on every page. You can have a different font for the title versus the body but keep those font choices consistent throughout the presentation.
Tip #4: Make sure the Font and Background Colors don't Clash.
Chose colors that compliment each other and are easily visible. Putting a yellow font on a white background won't work; but that same text color on a black background will pop.
Tip #5: Photos Should be Proportional.
If you add photos to your presentation, go to the Picture Tool tab and re-size the height or width on the top right part of the page. If you choose to re-size the width, the height will scale automatically. Try and standardize on the same width or height for each photo throughout the presentation.
Tip #6: Use Video and Sound.
Save all your video and sound files within the presentation. It is very important that you work with an onsite AV Technician to make certain the right speakers are available to project the sound to the audience. Without the proper sound system, your video is useless.
Tip #7: Compress Your Files.
Make certain to compress your videos and photos before distributing your content to conference service organizers. This will allow them to easily load your presentation if they rent iPads for attendees.
Tip #8: Rehearse Your Presentation at Least Once.
Before you deliver your presentation to the audience, meet with the AV technician to run through your talk from a sound, lighting and timing perspective. Even though you have given your presentation several times, you haven't delivered it in front of this audience or using this venue.
SmartSource Rentals is your one-shop stop when renting audio visual equipment. With 20 locations to serve you, they have a plethora of presentation services audio visual equipment for your next meeting or event!

Activists are Protesting a Pipeline. A DHS Helicopter Blasted Them With Debris.
Anti-pipeline protestors outside the state capitol in St. Paul, Minnesota in MarchTim Evans/NurPhoto/Zuma
In an apparent attempt to disperse a crowd of people protesting the construction of an oil pipeline in Minnesota, a Department of Homeland Security helicopter hovered above protesters yesterday, showering them with dust and debris.
Authorities denied that the dust storm was intentional and claimed that the helicopter had been sent to order the crowd to disperse, the Intercept reports. Still, low-flying helicopters are a common police tactic to intimidate protestors.
DHS/Border Patrol is using helicopter rotor wash to try to clear out activists out from an occupied #Line3 pump station north of Park Rapids. More than 24 activists are locked down to equipment inside. @MPRnews pic.twitter.com/ArTN6FAqwC
— Evan Frost (@efrostee) June 7, 2021
The demonstrators were engaging in civil disobedience against the construction of an oil pipeline that threatens to contaminate Mississippi River headwaters on Ojibwe tribal lands. Enbridge, the Canadian company building the pipeline, says new construction is necessary to replace the existing leaky and corroded crude oil pipeline. But the new pipeline will follow a different route, which activists say could harm the wild rice, sacred to the Ojibwe, grown in the area. (A spokesperson for the company also chided protesters for trespassing to the Intercept, comparing it to the attack on the Capitol on January 6.)
The protestors are also calling on President Biden to stop the construction of the pipeline, which mostly replaces an existing pipeline, as he did the Keystone XL pipeline his first week in office. Nevertheless, construction has continued, and the pipeline is more than halfway completed.


Exeter-based Lightfoot, the award-winning, government-supported in-vehicle driver improvement technology, is celebrating having been shortlisted for the prestigious 2017 Design in Innovation Awards, held at Innovate 2017, the UK's leading innovation show.
Based on Lightfoot's Exeter trial, where 100 private motorists had the device installed in their vehicles, the submission focused on the dramatic impact that its technology is having on drivers across the city.
Judged by an expert panel, which included Innovate UK Chief Executive Dr. Ruth McKernan, Lightfoot was selected as one of just eight businesses to make it through to the finals from a field of over 70 contenders, each of which had been hand selected by Innovate UK to showcase the brightest and boldest UK innovations to over 2,500 businesses from around the globe.
Lightfoot's entry was of particular interest to the judges as its in-vehicle device, described as the "Fitbit for cars and vans", has been used to transform the way individuals drive in the city of Exeter. By encouraging smoother, more efficient driving, Lightfoot is slashing pollution and fuel bills, while helping to reduce accidents on the road.
Installed in over 100 vehicles across the city, Lightfoot has helped cut CO2 by a tonne a week, lowering nitrous oxide emissions by 20% and reducing particulates by 15%. Of those participating in the trial, 99% of users experienced improved fuel economy, with average mpg gains in excess of 15%.
However, what really impressed the judges was Lightfoot's approach to competitive efficiency, which incentivizes Lightfoot users to drive more smoothly and considerately through the prospect of winning prizes. These prizes range from a year's supply of pies to a track day with Nigel Mansell. Combined with the real-time feedback that Lightfoot provides to the driver, Lightfoot instantly and consistently cuts pollution on the roads by linking rewards for better driving with connected car technology.
Dan Regan, Head of Engagement at Exeter-based Lightfoot commented: "Making it to the finals of the 2017 Design in Innovation Awards is a huge honour. It further endorses our work to help businesses, individuals and local authorities tackle pollution on the roads, providing a practical and deliverable solution here and now.
Earlier this year Lightfoot received almost £1million in Government funding from Innovate UK and The Centre for Connected and Autonomous Vehicles (CCAV) to further develop its technology. Combined with growing demand for its product from fleets, Lightfoot has expanded its team by 60% and is rapidly advancing a range of projects that will bring cleaner, greener and cheaper motoring to drivers across the world, making smoother driving simple, fun, social and addictive.
Within the next six months, Lightfoot plans to move into new, larger premises at Harcombe Cross on the outskirts of Exeter, which is currently being fitted out for both the Lightfoot team and its sister company, Ashwoods Electric Motors.
Lightfoot's next step is to take its technology, which is being used by hundreds of fleets across the UK to cut fuel bills, emissions and accidents, to the consumer audience.


This happens because, for instance, the project or the task is closed or the user is no longer allocated to that project.
My problem is when the task depicted in the message (in this case "Proposals") belongs to several projects. How to identify the project the task belongs to and fix it?
In the previous picture, the task "proposals" belongs to 6 different projects. This example only refers to a single day... If we consider the entire timesheet it is not possible to easily identify the correct one.
This is a problem that happens frequently.
Does anyone knows how to solve this?
Thank you for posting, will have the concerned PM shed some light around this behavior and if change is planned.
We have the same issue however if you go to 'view all timesheets', tick the timesheet which is showing errors, Submit, put in a comment (usually test), it will come up with a warning, click on the warning this should provide you with a little bit more information.
Thanks for the hint and for trying!
I definitely understand that the error message would not be helpful in the scenario you describe when a person is working on multiple tasks with the same name. We will be looking at enhancing our error message capability and I will keep this a specific use case to address.
Thanks for taking the time to provide us with feedback.
This is still something we'd like to address but unfortunately I don't have a timeline for it. In our new timesheet format that we've been working on, we plan to have validation errors that show next to the invalid data. So the error would show next to the offending task. We've just started adding the infrastructure for this, but it will be a bit of time before we add all the pieces.
I've marked this as an Idea and Under consideration so it gets reviewed and updated as we schedule this.


Earlier this week I got to preview the new collection COS is offering for this Autumn/Winter, and as always it did not disappoint.
COS always has remarkable pieces and inspired by a Japanese theme, this collection is full of shapes and amazing materials.
The men's collection's details are reduced to their essentials, as in the resin sculptures of Peter Alexander. A grey wool blazer is collarless, and is held only be a clip fastening. It is worn with a felted wool apron for new masculine proportions.
Like I mentioned Japanese inspired cloths are used for single-breasted blazers, worn with kimono V-neck jumpers and T-shirts.
Other inspirations for the collection include =: Tara Donovan; Oscar Niermeyer; Koji Enokura; Susumu Koshimizu, and Oyvind Tangen's photograph of the multi-coloured iceberg.
I also got to meet up with my good buddy Paul Ramos from The Style Choreo.

Rush Limbaugh (Jeff Malet, maletphoto.com)
Rush Limbaugh on tech blog politics: So stupid he's brilliant
Wake up, iGeneration! Biased pro-Google bloggers are just like the Republican-hating mainstream media
Check out this article! https://www.salon.com/2013/08/05/rush_limbaugh_on_tech_blog_politics_so_stupid_hes_brilliant/
A darkness has fallen over the world of tech blogs. On Friday, Rush Limbaugh focused his baleful attention on a new cultural battlefield, one in which Apple fanboys joust with the Google faithful. In the midst of endless flamewars, Limbaugh has been vouchsafed a great truth: Apple advocates are just like beleaguered Republicans.
[T]he online tech bloggers come down and are divided like the mainstream news guys are between Republicans and Democrats... I would venture to say that nine out of 10 bloggers writing high-tech hate Apple. Apple is the equivalent of the Republicans on these blogs, and Google, Android, and Samsung are the equivalent of the Democrats. They're perfect, they can't do anything wrong, they're ideal, and everybody hates Apple.
Media bias alert!
I'm betting that self-described "student of the media" Limbaugh found his "nine-out-of-ten" stat the same place he finds everything else -- in other words, he pulled it out of his ass. His stark dichotomy of tech-blogger bias does a great disservice to tech media diversity. Nine-out-of-ten tech bloggers may well be white and male, but they're equal opportunity haters, willing to trash Google as soon as praise it. Everybody despises everybody. (It's a sad statement on how far Microsoft has fallen that they don't even get a mention in Limbaugh's analysis.) And Limbaugh has obviously never said a critical word about Apple on air, or he would know that the notion that "everybody hates Apple" does not describe how one's inbox looks a few seconds after the unwary critic dares to say a discouraging word about anything that begins with a lower-case I.
But no matter -- Rush has a bigger point to make. Though he conceded that the vast majority of all tech bloggers, regardless of their allegiance are likely Democrats who consider Limbaugh an "old-fashioned, fuddy-duddy, kook, hayseed, racist, sexist, bigot, homophobe," he hopes that Apple bloggers, at least, can learn from their experience of overt media bias. "It would be a great teachable moment," he said.
I would love to just be able to get to one of these guys say, "Now, I want you to do something. The way you see these guys propping up Samsung and Google and Android and the way these guys are ripping Apple to shreds, would you try to see that in the mainstream media? Would you open your eyes and see what's going on in the mainstream media? Would you try to open your eyes and see that in the mainstream media, the Republican Party is Apple, and the Democrat Party is Samsung, Google, and Android."
Rush Limbaugh is hoping that once Apple bloggers realize how the rest of the tech media is unfairly biased against them, they will understand that the same is true of mainstream media against Republicans. They will see how Fox News is unfairly maligned, and House Republicans actually make sense.
Even Rush is willing to concede that any kind of mass tech blogger epiphany is unlikely to happen, because all these young hipsters already lean left. But he can dream, can't he? There's also no doubting the inspired brilliance of Limbaugh's analysis. Comparing Apple to the Republican party forces the kind of cognitive dissonance that makes one question the fabric of reality and shakes one's understanding of one's place in the universe. But when you think about it, "Think Different" is a pretty good way to describe Michele Bachmann.
I will also grant Limbaugh one nugget of truth. Apple's top-down, control-everything-about-the-interface, restrict-user-choice in line with the great Jobsian vision has often been contrasted with the everything goes, configure-it-however-you-want-it Android ethos pushed by Google. In this sense Apple's politics, stylistically, align with the familiar hard-core conservative Republicanism that treats any deviation from the party line as anathema. Whereas the Android free-for-all feels more big tent Democratic. I went shopping for a phone for my son on Sunday. The Android world is definitely multicultural in all its confounding, scary diversity. The Apple world is as monolithic as an Iowa Republican caucus meeting.
But, but, but, typically, Limbaugh's analysis is far too simplistic. He's missing the real political action! Forget about Apple and Google fanboys. That's a sideshow. Right now, the heat of the day is increasingly being generated by the clash between tech bloggers who are raising questions about how the tech economy is contributing to class stratification and inequality, and the tech bloggers who serve as little more than trade-press megaphones for industry propaganda.
The politics of libertarian utopianism -- give us our unchained Silicon Valley, free of any incumbent-protecting regulation, or give us death! -- are getting huge play all over the Internet. The critics occupy a much smaller space. To borrow Limbaugh's analysis, it's the people who are calling foul on this-app-will-change-the-world rhetorical bullshit who are the biased-against Republicans, the beleaguered minority in danger of being crushed by the mainstream.
Follow the money, Rush! The vast amounts of tech advertising money that prop up the tech blogosphere have created a warm and welcoming space for voices that support Silicon Valley capitalist idealism. In this universe, Ayn Rand is the 800-pound gorilla and Karl Marx is a gnat buzzing around in Mark Zuckerberg's ear.
I hope everybody follows Rush Limbaugh's advice. The sooner we all see how the majority of tech coverage serves the interests of tech capital, the sooner we will be able to throw off our chains of unthinking fan-boyism, no matter what brand is tattooed on our foreheads.

10.1ISO 3601 Fluid power systems — O-rings
Mechanical, toroid gasket that seals an interface
This article is about the mechanical seal. For other uses, see Oring.
Typical O-ring and application
An O-ring, also known as a packing or a toric joint, is a mechanical gasket in the shape of a torus; it is a loop of elastomer with a round cross-section, designed to be seated in a groove and compressed during assembly between two or more parts, forming a seal at the interface.
The O-ring may be used in static applications or in dynamic applications where there is relative motion between the parts and the O-ring. Dynamic examples include rotating pump shafts and hydraulic cylinder pistons. Static applications of O-rings may include fluid or gas sealing applications in which: (1) the O-ring is compressed resulting in zero clearance, (2) the O-ring material is vulcanized solid such that it is impermeable to the fluid or gas, and (3) the O-ring material is resistant to degradation by the fluid or gas.[1] The wide range of potential liquids and gases that need to be sealed has necessitated the development of a wide range of materials.[2]
O-rings are one of the most common seals used in machine design because they are inexpensive, easy to make, reliable and have simple mounting requirements. They have been tested to seal up to 5,000 psi (34 MPa) of pressure.[3] The maximum recommended pressure of an O-ring seal depends on the seal hardness, material, cross-sectional diameter, and radial clearance.[4]
Manufacturing[edit]
O-rings can be produced by extrusion, injection molding, pressure molding or transfer molding.[5]
The first patent for the O-ring is dated May 12, 1896, as a Swedish patent. J. O. Lundberg, the inventor of the O-ring, received the patent.[6] The US patent[7][8] for the O-ring was filed in 1937 by a then 72-year-old Danish-born machinist, Niels Christensen.[9] In his previously filed application in 1933, resulting in Patent 2115383,[10] he opens by saying, "This invention relates to new and useful improvements in hydraulic brakes and more particularly to an improved seal for the pistons of power conveying cylinders." He describes "a circular section ring ... made of solid rubber or rubber composition", and explains, "this sliding or partial rolling of the ring ... kneads or works the material of the ring to keep it alive and pliable without deleterious effects of scuffing which are caused by purely static sliding of rubber upon a surface. By this slight turning or kneading action, the life of the ring is prolonged." His application filed in 1937 says that it "is a continuation-in-part of my copending application Serial No. 704,463 for Hydraulic brakes, filed December 29, 1933, now U. S. Patent No. 2,115,383 granted April 26, 1938".
Soon after migrating to the United States in 1891, he patented an air brake system for streetcars (trams). Despite his legal efforts, the patents were passed from company to company until they ended up at Westinghouse.[9] During World War II, the US government commandeered the O-ring patent as a critical war-related item and gave the right to manufacture to other organizations. Christensen received a lump sum payment of US$75,000 for his efforts. Litigation resulted in a $100,000 payment to his heirs in 1971, 19 years after his death.[11]
Theory and design[edit]
O-ring mounting for an ultra-high vacuum application.[12] Pressure distribution within the cross-section of the O-ring. The orange lines are hard surfaces, which apply high pressure. The fluid in the seams has lower pressure. The soft O-ring bridges the pressure over the seams.
O-rings are available in various metric and inch standard sizes. Sizes are specified by the inside diameter and the cross section diameter (thickness). In the US the most common standard inch sizes are per SAE AS568C specification (e.g. AS568-214). ISO 3601-1:2012 contains the most commonly used standard sizes, both inch and metric, worldwide. The UK also has standards sizes known as BS sizes, typically ranging from BS001 to BS932. Several other size specifications also exist.
Typical applications[edit]
Successful O-ring joint design requires a rigid mechanical mounting that applies a predictable deformation to the O-ring. This introduces a calculated mechanical stress at the O-ring contacting surfaces. As long as the pressure of the fluid being contained does not exceed the contact stress of the O-ring, leaking cannot occur. The pressure of the contained fluid transfers through the essentially incompressible O-ring material, and the contact stress rises with increasing pressure. For this reason, an O-ring can easily seal high pressure as long as it does not fail mechanically. The most common failure is extrusion through the mating parts.
The seal is designed to have a point contact between the O-ring and sealing faces. This allows a high local stress, able to contain high pressure, without exceeding the yield stress of the O-ring body. The flexible nature of O-ring materials accommodates imperfections in the mounting parts. But it is still important to maintain good surface finish of those mating parts, especially at low temperatures where the seal rubber reaches its glass transition temperature and becomes increasingly inflexible and glassy. Surface finish is also especially important in dynamic applications. A surface finish that is too rough will abrade the surface of the O-ring, and a surface that is too smooth will not allow the seal to be adequately lubricated by a fluid film.
Vacuum applications[edit]
In vacuum applications, the permeability of the material renders the point contacts unusable. Instead, higher mounting forces are used and the ring fills the whole groove. Also, round back-up rings are used to save the ring from excessive deformation.[13][14][15] Because the ring feels[colloquialism] the ambient pressure and the partial pressure of gases only at the seal, their gradients will be steep near the seal and shallow in the bulk (opposite to the gradient of the contact stress[16] (See Vacuum flange#KF.2FQF.) High-vacuum systems below 10−9 Torr use copper or nickel O-rings. Also, vacuum systems that have to be immersed in liquid nitrogen use indium O-rings, because rubber becomes hard and brittle at low temperatures.
High temperature applications[edit]
In some high-temperature applications, O-rings may need to be mounted in a tangentially compressed state, to compensate for the Gow-Joule effect.
Sizes[edit]
O-rings come in a variety of sizes. Society of Automotive Engineers (SAE) Aerospace Standard 568 (AS568)[17] specifies the inside diameters, cross-sections, tolerances, and size identification codes (dash numbers) for O-rings used in sealing applications and for straight thread tube fitting boss gaskets. British Standard (BS) which are imperial sizes or metric sizes. Typical dimensions of an O-ring are internal dimension (id), outer dimension (od) and thickness / cross section (cs)
Metric O-rings are usually defined by the internal dimension x the cross section. Typical part number for a metric O-ring - ID x CS [material & shore hardness] 2x1N70 = defines this O-ring as 2mm id with 1mm cross section made from Nitrile rubber which is 70Sh. BS O-rings are defined by a standard reference.
The World's Largest O-ring was produced in a successful Guinness World Record attempt by Trelleborg Sealing Solutions Tewkesbury partnered with a group of 20 students from Tewkesbury School. The O-ring once finished and placed around the Medieval Tewkesbury Abbey had a 364 m (1,194 ft) circumference, an approximately 116 m (381 ft) inner diameter, and a cross section of 7.2 mm (0.28 in).[18]
Material[edit]
Some small O-rings
O-ring selection is based on chemical compatibility, application temperature, sealing pressure, lubrication requirements, durometer, size and cost.[19]
Synthetic rubbers - Thermosets:
Butadiene rubber (BR)
Butyl rubber (IIR)
Chlorosulfonated polyethylene (CSM)
Epichlorohydrin rubber (ECH, ECO)
Ethylene propylene diene monomer (EPDM): good resistance to hot water and steam, detergents, caustic potash solutions, sodium hydroxide solutions, silicone oils and greases, many polar solvents and many diluted acids and chemicals. Special formulations are excellent for use with glycol-based brake fluids. Unsuitable for use with mineral oil products: lubricants, oils, or fuels. Peroxide-cured compounds are suitable for higher temperatures.[20]
Ethylene propylene rubber (EPR)
Fluoroelastomer (FKM): noted for their very high resistance to heat and a wide variety of chemicals. Other key benefits include excellent resistance to aging and ozone, very low gas permeability and the fact that the materials are self-extinguishing. Standard FKM materials have excellent resistance to mineral oils and greases, aliphatic, aromatic and chlorinated hydrocarbons, fuels, non-flammable hydraulic fluids (HFD) and many organic solvents and chemicals. Generally not resistant to hot water, steam, polar solvents, glycol-based brake fluids and low molecular weight organic acids. In addition to the standard FKM materials, a number of specialty materials with different monomer compositions and fluorine content (65% to 71%) are available that offer improved chemical or temperature resistance and/or better low temperature performance.[20]
Nitrile rubber (NBR, HNBR, HSN, Buna-N): a common material for o-rings because of its good mechanical properties, its resistance to lubricants and greases, and its relatively low cost. The physical and chemical resistance properties of NBR materials are determined by the acrylonitrile (ACN) content of the base polymer: low content ensures good flexibility at low temperatures, but offers limited resistance to oils and fuels. As the ACN content increases, the low temperature flexibility reduces and the resistance to oils and fuels improves. Physical and chemical resistance properties of NBR materials are also affected by the cure system of the polymer. Peroxide-cured materials have improved physical properties, chemical resistance and thermal properties, as compared to sulfur-donor-cured materials. Standard grades of NBR are typically resistant to mineral oil-based lubricants and greases, many grades of hydraulic fluids, aliphatic hydrocarbons, silicone oils and greases and water to about 176 °F (80 °C). NBR is generally not resistant to aromatic and chlorinated hydrocarbons, fuels with a high aromatic content, polar solvents, glycol-based brake fluids and non-flammable hydraulic fluids (HFD). NBR also has low resistance to ozone, weathering and aging. HNBR has considerable improvement of the resistance to heat, ozone and aging, and gives it good mechanical properties.[20]
Perfluoroelastomer (FFKM)
Polyacrylate rubber (ACM)
Polychloroprene (neoprene) (CR)
Polyisoprene (IR)
Polysulfide rubber (PSR)
Sanifluor (FEPM)
Silicone rubber (SiR): noted for their ability to be used over a wide temperature range and for excellent resistance to ozone, weathering and aging. Compared with most other sealing elastomers, the physical properties of silicones are poor. Generally, silicone materials are physiologically harmless so they are commonly used by the food and drug industries. Standard silicones are resistant to water up to 212 °F (100 °C), aliphatic engine and transmission oils and animal and plant oils and fats. Silicones are generally not resistant to fuels, aromatic mineral oils, steam (short term to 248 °F (120 °C) is possible), silicone oils and greases, acids or alkalis. Fluorosilicone elastomers are far more resistant to oils and fuels. The temperature range of applications is somewhat more restricted.[20]
Styrene-butadiene rubber (SBR)
Thermoplastics:
Thermoplastic elastomer (TPE) styrenics
Thermoplastic polyolefin (TPO) LDPE, HDPE, LLDPE, ULDPE
Thermoplastic polyurethane (TPU) polyether, polyester: Polyurethanes differ from classic elastomers in that they have much better mechanical properties. In particular they have a high resistance to abrasion, wear and extrusion, a high tensile strength and excellent tear resistance. Polyurethanes are generally resistant to aging and ozone, mineral oils and greases, silicone oils and greases, nonflammable hydraulic fluids HFA & HFB, water up to 122 °F (50 °C) and aliphatic hydrocarbons.[20]
Thermoplastic etheresterelastomers (TEEEs) copolyesters
Thermoplastic polyamide (PEBA) Polyamides
Melt Processible Rubber (MPR)
Thermoplastic Vulcanizate (TPV)
Chemical Compatibility:
Air, 200 to 300 °F (93 to 149 °C) – Silicone
Beer - EPDM
Chlorine Water – Viton (FKM)
Gasoline – Buna-N or Viton (FKM)
Hydraulic Oil (Petroleum Base, Industrial) – Buna-N
Hydraulic Oils (Synthetic Base) – Viton
Water – EPDM
Motor Oils – Buna-N
Other seals[edit]
O-ring and other sealing profiles
Although the O-ring was originally so named because of its circular cross section, there are now variations in cross-section design. The shape can have different profiles, such as an x-shaped profile, commonly called the X-ring, Q-ring, or by the trademarked name Quad Ring. When squeezed upon installation, they seal with 4 contact surfaces—2 small contact surfaces on the top and bottom.[22] This contrasts with the standard O-ring's comparatively larger single contact surfaces top and bottom. X-rings are most commonly used in reciprocating applications, where they provide reduced running and breakout friction and reduced risk of spiraling when compared to O-rings.
There are also rings with a square profile, commonly called square-cuts, lathe cuts, tabular cut or Square rings. When O-rings were selling at a premium because of the novelty, lack of efficient manufacturing processes and high labor content, Square rings were introduced as an economical substitution for O-rings. The square ring is typically manufactured by molding an elastomer sleeve which is then lathe-cut. This style of seal is sometimes less expensive to manufacture with certain materials and molding technologies (compression molding, transfer molding, injection molding), especially in low volumes. The physical sealing performance of square rings in static applications is superior to that of O-rings, however in dynamic applications it is inferior to that of O-rings. Square rings are usually used only in dynamic applications as energizers in cap seal assemblies. Square rings can also be more difficult to install than O-rings.
Similar devices with a non-round cross-sections are called seals, packings or gaskets. See also washers.[23]
Automotive cylinder heads are typically sealed by flat gaskets faced with copper.
Knife edges pressed into copper gaskets are used for high vacuum.
Elastomers or soft metals that solidify in place are used as seals.
Failure modes[edit]
O-ring materials may be subjected to high or low temperatures, chemical attack, vibration, abrasion, and movement. Elastomers are selected according to the situation.
There are O-ring materials which can tolerate temperatures as low as −328.0 °F (−200 °C) or as high as 482 °F (250 °C). At the low end, nearly all engineering materials become rigid and fail to seal; at the high end, the materials often burn or decompose. Chemical attack can degrade the material, start brittle cracks or cause it to swell. For example, NBR seals can crack when exposed to ozone gas at very low concentrations, unless protected. Swelling by contact with a low viscosity fluid causes an increase in dimensions, and also lowers the tensile strength of the rubber. Other failures can be caused by using the wrong size of ring for a specific recess, which may cause extrusion of the rubber.
Elastomers are sensitive to ionizing radiation. In typical applications, O-rings are well-protected from less-penetrating radiation such as ultraviolet and soft X-rays, but more-penetrating radiation such as neutrons may cause rapid deterioration. In such environments, soft metal seals are used.
There are a few common reasons for O-ring failure:
Installation damage – This is caused by improper installation of the O-ring.
Spiral failure – Found on long-stroke piston seals and – to a lesser degree – on rod seals. The seal gets "hung up" at one point on its diameter (against the cylinder wall) and slides and rolls at the same time. This twists the O-ring as the sealed device is cycled and finally causes a series of deep spiral cuts (typically at a 45 degree angle) on the surface of the seal.
Explosive decompression – An O-ring embolism, also called gas expansion rupture, occurs when high pressure gas becomes trapped inside the elastomeric seal element. This expansion causes blisters and ruptures on the surface of the seal.
Space Shuttle Challenger disaster[edit]
Main article: Space Shuttle Challenger disaster
The failure of an O-ring seal was determined to be the cause of the Space Shuttle Challenger disaster on January 28, 1986. A crucial factor was cold weather prior to the launch. This was famously demonstrated on television by Caltech physics professor Richard Feynman, when he placed a small O-ring into ice-cold water, and subsequently showed its loss of flexibility before an investigative committee.
The material of the failed O-ring was FKM, which was specified by the shuttle motor contractor, Morton-Thiokol. When an O-ring is cooled below its glass transition temperature Tg, it loses its elasticity and becomes brittle. More importantly, when an O-ring is cooled near (but not beyond) its Tg, the cold O-ring, once compressed, will take longer than normal to return to its original shape. O-rings (and all other seals) work by producing positive pressure against a surface, thereby preventing leaks. On the night before the launch, exceedingly low air temperatures were recorded. Due to this, NASA technicians performed an inspection; the ambient temperature was within launch parameters, and the launch sequence was allowed to proceed. However, the temperature of the rubber O-rings remained significantly lower than that of the surrounding air. During his investigation of the launch footage, Feynman observed a small out-gassing event from the Solid Rocket Booster at the joint between two segments in the moments immediately preceding the disaster. This was blamed on a failed O-ring seal. The escaping high-temperature gas impinged upon the external tank, and the entire vehicle was destroyed as a result.
Since the accident, rubber production companies have enacted changes. Many O-rings now come with batch and cure date coding, as is done in medicine production, to precisely track and control distribution. For aerospace and military applications, O-rings are usually individually packaged and labeled with the material, cure date, and batch information. O-rings can, if needed, be recalled off the shelf.[24] Furthermore, O-rings and other seals are routinely batch-tested for quality control by the manufacturers, and often undergo quality assurance testing several more times by the distributor and ultimate end-users.
As for the boosters themselves, NASA and Morton-Thiokol redesigned them with a new joint design, which now incorporated three O-rings instead of two, with the joints themselves having onboard heaters that can be turned on when temperatures drop below 50 °F (10 °C). No O-ring issues have occurred since Challenger, and they did not play a role in the Space Shuttle Columbia disaster of 2003.

An O-ring is one of the simplest, yet highly critical, precision mechanical components ever developed. However, there are new[when?] advances that may take some of the burden of critical sealing away from the O-ring. There are cottage industries of elastomer consultants assisting in designing O-ring-less pressure vessels. Nano-technology-rubber is one such new frontier. Presently, these advancements are increasing the importance of O-rings. Since O-rings encompass the areas of chemistry and material science, any advancement in nano-rubber will affect O-ring production companies.
Already, there are elastomers filled with nano-carbon and nano-PTFE and molded into O-rings used in high-performance applications. For example, carbon nanotubes are used in electrostatic dissipative applications and nano-PTFE is used in ultra pure semiconductor applications. The use of nano-PTFE in fluoroelastomers and perfluoroelastomers improves abrasion resistance, lowers friction, lowers permeation, and can act as clean filler.
Using conductive carbon black or other fillers can exhibit the useful properties of conductive rubber, namely preventing electrical arcing, static sparks, and the overall build-up of charge within rubber that may cause it to behave like a capacitor (electrostatic dissipative). By dissipating these charges, these materials, which include doped carbon-black and rubber with metal filling additives, reduce the risk of ignition, which can be useful for fuel lines.

Lucas Oil Pro Motocross Championship Gears Up for Landmark 50th Anniversary Season

MX Sports Pro Racing Unveils Commemorative Logo for Summer Campaign
MORGANTOWN, WV – January 12, 2022 – (Motor Sports NewsWire) – With the turn of the new year, preparations are formally underway for the landmark 50th Anniversary of the Lucas Oil Pro Motocross Championship. In conjunction with each respective Nationals event organizer, the sanctioning body at AMA Pro Racing, and longtime series title sponsor Lucas Oil, MX Sports Pro Racing will celebrate the storied legacy of the world's most prestigious off-road motorcycle racing series, beginning with the introduction of a new commemorative logo for the 2022 season.
"After two years of challenges to successfully implement a championship calendar we are incredibly eager for the season that lies ahead this summer. We'll have an opportunity to properly celebrate the 50th anniversary of this storied championship and pay homage to the individuals and venues who helped elevate American motocross to the forefront of the sport on a global scale," said Davey Coombs, President of MX Sports Pro Racing. "We also want to use this season as an opportunity to recognize the entities that have played an integral role in our ability to build on this indelible legacy over the past 14 years since MX Sports Pro Racing was awarded the role of series organizers."
The 2022 Lucas Oil Pro Motocross Championship logo serves as a symbol of five decades showcasing the world's finest motocross talent, hallmarked by a laurel wreath consisting of 50 leaves surrounding the anniversary numeral and the series' longevity (1972-2022). Additionally, gold now compliments the series' foundational blue colorway in an embrace of the "golden anniversary" of the 2022 season. The Lucas Oil branding provides a prominent accent piece featuring the company's familiar red colorway along with four stars that serve as a nod to America's role in elevating the sport through its most distinguished championship.
When the series was first introduced in 1972 it formalized a permanent, stand-alone national championship for homegrown talent to showcase their prowess under the banner of the American Motorcyclist Association (AMA). It didn't take long for the Pro Motocross Championship to evolve into a true global competition between domestic and international athletes, and for the past 50 years it has brought the best riders from six continents to the United States in a quest for success and stardom, competing on the most hallowed grounds in all of motocross.

Fittingly, the 50th anniversary will serve as the most prominent representation of the global influence of the Lucas Oil Pro Motocross Championship as a pair of international riders will carry the number one plate in both the 450 Class and 250 Class for the first time in history. Frenchman Dylan Ferrandis is just the third European rider ever in the 450 Class to serve as reigning champion, while Australian Jett Lawrence enters uncharted territory as the first defending titleholder in the 250 Class from the "Land Down Under."
While most of the attention deservedly centers on the talent-rich collection of athletes preparing to embark on the grueling 24-moto journey this summer, many of the venues that will compose the 2022 schedule have been fixtures of the heritage of American motocross over the past half century. Whether it's New York's legendary Unadilla MX or California's storied Hangtown Classic, both of which predate the Pro Motocross Championship, Michigan's renowned RedBud MX, Massachusetts infamous The Wick 338, or Pennsylvania's iconic High Point Raceway, these tracks have played an equally pivotal role in the ascension of American motocross as the hundreds of riders who have stood on the podium since that inaugural 1972 season. It's a rare juxtaposition that makes the Lucas Oil Pro Motocross Championship one of motorsports' most distinguished competitions.
Historic venues, like New York's legendary Unadilla MX, will be celebrated
as they extend their legacies during the landmark 2022 season.
The 50th Anniversary of the Lucas Oil Pro Motocross Championship will kick off over Memorial Day Weekend, on May 28, for the proverbial start of the summer and will travel throughout the country to the sport's most high-profile venues for 12 captivating rounds, concluding on September 3 during Labor Day Weekend.

Heading on campus, the H&M Men's Studio AW2018 Athletic Prep Collection embraces classic, Ivy League collegiate style, but subjects it to a series of clever contemporary and rebellious punk revisions. Set the new curriculum in an authentic retro duffel coat or a corduroy-collared, coffee-hued, recycled-wool western jacket paired with a varsity letter sweater.
Go mad-for-plaid with freshyet- fierce punk trousers and the cropped puffer jacket, its traditional saturated tartan given a modish update thanks to an athletic silhouette. Or entertain the preppy appeal of chunky cord slacks in a crisp navy cut. "For this autumn collection, we wanted to combine H&M Studio Man's signature sportswear-oriented mentality with a traditional preppy aesthetic to offer a roster of authentic menswear classics, in premium fabrics, that will surprise our customer thanks to subtle, modern twists," says Adam Gauffin, Concept Designer at H&M Studio menswear.
The key piece includes the traditional toggle-fastened navy duffel coat in a sporty, scuba-style wool and play the class ace via the navy varsity sweatshirt, with its authentic Harvard University shield emblem.
It's the perfect match for the clean-cut navy pea coat. More expert layering statements include the tartan puffer jacket, a casually contemporary take on dapper plaid, and the wool collegiate letter sweater, in a cosy melange of steel grey and cream.
Statement-makers will love the cable knit vest, with its intellectual undercurrents, and the bold, saturated check tartan trousers, cut to flatter and the finishing touch with chunky wool argyle beanie.
The women Neo-Noir Chic collection taking the dream logic aesthetic of the cult series Twin Peaks as inspiration, the H&M Studio AW 2018 collection is a mix of ladylike statement pieces and borrowed-from-the-boys wardrobe classics. Fifties movie icons, with their era-defining looks, provide further nostalgic stimulus.
Opt for the chic precision of a sculpting wool dress and a cropped wool cardigan, worn under a nipped-in coated cotton trench coat. Or embrace your inner lumberjack, with the must-have indigo precision denim jacket and sturdy turn-up jeans, a jersey turtleneck lingering underneath.
Then there's the enlivening neon pop of a fuchsia-red feminine pleated skirt, set against the subversive wood grain print on a grungy viscose-silk suit. "With H&M Studio, we love the play between the feminine and masculine and this year we added a 50's twist – there are ultra-feminine options combined with mannish details and super-classic pieces that invite you to create your own distinctive look," says Pernilla Wohlfahrt, H&M's Design Director.
Why choose just one look when you can play with an entire spectrum? From square-toed boots to college kid cardigans; rough-and-ready selvedge denim to super-slick suiting; hard-edged biker jackets to bow-tied blouses, the H&M Studio collection has a neo-noir impulse this autumn, but there are multiple modern ways to wear it now.
The key pieces includes the ribbed funnel neck collar leather biker jacket, channel classic chic with the navy double-breasted wool pea coat or the crisp mini trench coat, with its nipped-in silhouette. The best news: they work with everything. The same goes for the square-toed chunky boots in shiny black leather, this season's spotlight accessory, which will instantly infuse anything from the viscose neck-tie blouse to the rusty-hued cropped wool cardigan with urban cool. Crisp, selvedge denim turn-up trousers, in autumn's key high-waisted, straight-leg cut, are equally desirable. And don't leave the house without the friendship heart pendant necklace.


In his first college wrestling match for Skyline College, 18-year-old Jean Leazard came out, went right after his opponent and took him down.
This Floridian native has been wrestling since 9th grade and has placed in state twice in high school. Two-time district champ and two time regional champ.
Coach Creighton praises Leazard highly for the great talent he's already shown and his potential.
Come out and cheer on Leazard and all the members of the wrestling team in their home meet at Terra Nova High School in Pacifica at 7:00 p.m.

Living In Between
The strange familiarity of divided Belfast.
Mar|Apr 09 Contents
By Martha Cooney | We sat in a council meeting room just outside Belfast: requisite tea tray on the table, notebooks out, seven sets of eyes on me. The circumstance seemed minor. There was a territorial and financial overlap between two community-development projects, and the nonprofit I worked for had assembled the leaders of two local groups in an effort to use grant money more effectively. Sounds easy, until the details: one group was Protestant, one Catholic. Despite living within the same housing estate, neither side had any relationship with the other.
I was the neutral party, required to get everyone around the table to join forces.
This kind of diplomacy hadn't really figured in my job description, but in Belfast, where sectarian divisions permeate every aspect of life, it was inevitable. The meeting represented larger divisions that still persist in Northern Ireland, long-lasting shock waves from the Troubles that the city is endlessly trying to shake off. My role as an American interloper was to slip unnoticed between the two sides. My own Irish Catholic background did not seem to matter. Writing in American underneath the Catholic box I had to tick on job applications—or sometimes ignoring the boxes altogether—I went ahead with my mouth shut, allowed into the complicated psyche of both sides of Northern Ireland.
My first three months in the city had given me a crash course in the unwritten rules of the Belfast social code. Words and phrases were a giveaway of either Protestantism or Catholicism—starting with the matter of what to call the place we lived in. "Northern Ireland," I was corrected with a half-joking, half-not tone by one of my Protestant coworkers when I made the mistake of calling it just Ireland. Among other acquaintances, however, it would have been offensive to say we were in the United Kingdom. Even names like region, the six counties, the province, and Ulster all had different connotations that belied your sympathies.
Sometimes I felt like I was on a game show, guessing at someone's identity in order to pick the appropriate phrase. But it wasn't the first time I had experienced this chameleon sensation. In a way, it was like being at Penn all over again.
I didn't have to drive very far to get from my childhood home to my freshman room in Hill House. But the journey from Northeast Philadelphia to the Penn campus was like traveling to another universe. There were brands and styles I'd never heard of (North Face, Lacoste, J. Crew pants with small animals on them), foods I'd never tasted (sushi, naan, portobello mushrooms), and entire conversations that revolved around words that meant nothing to me (Vail, Phillips Exeter, consulting). Chalking it up to my family's humble background didn't make things much easier, especially since I considered myself more privileged than plenty of other people in the city. Entering a classroom full of students wearing suits, heels, and pearls was confusing. Was I crazy, sitting there in my sweatpants, or were they? Meanwhile, I would meet girls whose impeccable diction was the result of voice coaches hired to train away their hometown accents—Philadelphia accents, in fact. Cash seemed to flow endlessly. The price of a new laptop clearly had not bothered the guy in our hall who threw his computer against the wall before jumping up and down on it in a fit of frustration. (Engineering students from another floor scrambled to grab the pieces.)
And undergraduate notions about Northeast Philly showed that the incomprehension went both ways. "I hear that's kind of ghetto," I remember someone telling me when I named my home. He sure must have been from out of town. Most Philadelphians would have rolled their eyes at me for hailing from the area reputed to be the most ignorant, the most white, and the least tough in town.
Community work at Penn brought its own frustrations. Well-meaning students were always sweeping in to save West Philadelphia with their research-based academic service projects, or romanticizing "this amazing, really AMAZING" welfare recipient they had encountered. Despite our joint devotion to common causes, I couldn't help but feel a gap separating me from other students. Once, in a political science class that focused on poverty, we worked with a community organization to plan a dinner at the home of a family in Northeast Philadelphia. The familiarity of the houses, the layout of the block—it all felt so normal and homey to me as we neared our destination. In fact, we were on a street five minutes from my first childhood home. Yet for my Penn friends it was foreign territory. Afterwards, one girl marveled at the openness of the family members who had hugged her goodbye; she was not used to that kind of warmth, she said, even in her own family. It was like other students were learning a new language I already knew—but it still ended up sounding foreign to my ears.
Eventually I cracked the code, and figured out how to slip across the dividing line when it gave me an advantage. I became an expert at dangling my new Penn-ness in front of the noses of potential employers. I worked out when to put the dropped g's back onto the end of my gerunds, when to avoid the iconic Philly Yo! But mostly I found safety in silence. I didn't want to be shut out of either world, but I didn't want to be boxed in either.
In Belfast it was the same for me; I had the privilege of easing in and out of both sides. The difference was that in Northern Ireland, the stakes were higher. People here don't have the option to break out of their identity. It's something they can never get away from.
For one of my Catholic friends, driving through East Belfast was a strange experience; she had never been there in her life. Panic spread among the family I was staying with when riots kicked off in their sleepy seaside town, where a bar was invaded and a carjacked vehicle set on fire, smoke billowing against green hills patrolled by grazing sheep. There were frantic calls warning everyone to lock their doors.
As time went on I realized that I was not immune. Neutrality was impossible. Running an errand in the Sandy Row estate—whose Protestant residents have emblazoned their domain with the red, white, and blue of the Union Jack—I fretted that I must be sticking out.
Being Irish Catholic had been a central part of my identity my whole life. I'd attended Catholic elementary school and high school, and held down summer jobs at a Catholic-run camp. Both of my parents worked for the Archdiocese of Philadelphia. After spending a college semester in Dublin, I brought home a huge tricolor that hung in my room. But in Belfast, both the British and the Irish colors sparked anxiety whenever I saw them. What's more, the Catholic neighborhoods had started to fill me with more tension than the Protestant sections where I mostly worked. Had I absorbed the mentality of a side that wasn't even "mine"? Or was it the constant back-and-forth that brought about a feeling of never completely belonging? Once again I found myself taking shelter in silence—only this time it was a part of the cultural code. As Seamus Heaney put it: The famous/Northern reticence, the tight gag of place/and times. Where to be saved you only must save face/And whatever you say, you say nothing.
The stifling feeling Heaney described settled around our council meeting table, where for once it was my responsibility to speak up. I had to create a space where people could make headway on the issues at hand. I awkwardly opened the floor and people started to talk. There were introductions, questions about what the other group was doing, and slowly, efforts to break out of the long habit of being neighbors without being neighborly. The tension wasn't going to fade away entirely, and trust was going to be halting and hesitant, but they were getting somewhere. I started to breathe more easily, easing into the comfort of neutrality as the groups figured out a plan to work together.
I'll be returning this year to Belfast, and the game of navigating a divided culture. Part of me wants to show more of a voice, but the same caution I felt during my undergraduate years has not disappeared, and slipping into my armor of safety still feels appealing. I know it can't last forever. When you can partway belong in any place, you never fully belong anywhere. But for now I am content, even if it is the contentment of a stringless balloon: floating along with others but tied tight to no one.
