A scientific study on the effects of terahertz radiation (used in some body scanner imaging systems).

ABSTRACT

We consider the influence of a terahertz field on the breathing dynamics of double-stranded DNA. We model the spontaneous formation of spatially localized openings of a damped and driven DNA chain, and find that linear instabilities lead to dynamic dimerization, while true local strand separations require a threshold amplitude mechanism. Based on our results we argue that a specific terahertz radiation exposure may significantly affect the natural dynamics of DNA, and thereby influence intricate molecular processes involved in gene expression and DNA replication.

Sweaty armpits could trigger airport scanners

24 April 2012 | Source | Permalink | comments: 1

Categories: [ Full Body Scanners ]

FULL-BODY scanners being introduced at Australia's eight international airports could be triggered by sweaty armpits and a passenger's posture, a counter-terrorism unit has warned.

In German trials of the body-scanning technology, false alarms were recorded and sweaty armpits were among the culprits, slowing down departure lanes, according to Tasmania's Department of Police and Emergency Management.

"There are already long delays at airports, so this issue needs to be addressed," the unit says in a submission to a Senate committee inquiring into the millimetre-wave body scanners.

Germany ditched the scanners after too many false alarms but they are in use in some parts of Europe and the US.

The Australian Airline Pilots Association has raised similar concerns about the potential for false positives and has said it wants screening with the machines to be voluntary.

A spokeswoman for Infrastructure and Transport Minister Anthony Albanese defended the technology.

Are airport body scanners safe? Radiation expert Dr. John Moulder to give lecture

An expert in the health risks of human exposure to radiation will speak at the University of Wisconsin-Milwaukee (UWM) about airport whole-body scanners on May 4.

Hosted by the UWM Department of Physics, Dr. John Moulder of the Medical College of Wisconsin (MCW) will address the considerable public concern about possible health effects posed by the backscatter X-ray and millimeter-wave radar whole-body scanners that are used at many airports.

The free event begins at 8 p.m. in the Physics building, 1900 E. Kenwood Blvd., room 137.

As the summer travel season begins, Dr. Moulder will discuss the research showing that these scanners pose only negligible radiation risks if used as intended. However, he will also outline the difficulty in proving their safety using publicly accessible data that shields information on the machinery’s specifications and methods of measurement.

He makes the argument that more openness is needed, as is independent review and regulation. Publicly accessible, and preferably peer-reviewed, evidence is needed that the units (not just the prototypes) meet widely accepted safety standards.

Moulder is professor and director of radiation biology at MCW, and holds two advanced degrees from Yale University. There will be time for discussion and questions after the presentation.

TARGET has a new employee - a 3D body scanner - charged with making sure clothes fit better.

TARGET body scanner

The national retailer is spending $1 million on the technology that will measure the dimensions of 20,000 men and women as part of a national survey to update their designs.

Perth shoppers will be able step into the scanner from May 25 to 29 in the company's Whitfords store.

Target managing director Dene Rogers said customers were frustrated and confused by inconsistent sizing. It was the main reason clothes were returned.

"By taking 60 seconds to come and be scanned consumers will not only find out their exact measurements, they'll be helping Target find out what size Australians really are today so that we can make clothes that really fit," Mr Rogers said.

How Full-Body Scanners Work – and Fail

TSA has been introducing full-body scanners to perform a virtual strip search of air travelers. Although technically travelers have the right to opt out, the TSA discourages this behavior with aggressive and invasive pat-down searches. Initially, TSA denied punitive pat-down searches. Then they acknowledged testing a “more aggressive pat-down technique.” TSA began a more widespread implementation of this tactic at the beginning of November, and TSA agents have reportedly been quite open about that fact that the “enhanced” pat-down searches are specifically aimed to be so offensive as to coerce passengers into the scanners. In a blog post otherwise bluntly supportive of full-body scanning (the title, “Shut Up And Get In The Scanner,” gives a good idea of the tone of the writing), one former TSA screener writes:

It is a terror tactic by TSA to get you to walk through the more thorough body scanner.  I can’t defend TSA on this one.  I have talked to the TSA officers and it is no more effective than the old pat down procedure.  They tested it out with trainers and each other.  It is purely a terror tactic by TSA.

Other bloggers (with sharper tongues and stronger stomachs than I) have exhaustively documented the steaming mass of epic fail that is the TSA’s new policy. The aim of this post is to explain how full-body scanners work – and fail.

There are two kinds of full-body scanners: those based on backscatter X-ray technology and those based on millimeter wave technology.

Total Body Scam? — Taking your money and freedom, (and coming to Australia too)

Was it just me? Was I the only one who noticed a tiny announcement in February that Airport Scanners were coming to Australia, the land where terrorists haven’t landed (yet), and … wait for it… there would be no (NO!) — opt — out– clause. Did I hear that correctly?

And the crowd roared (about the cricket), nobody said a word about the scanners, and the ten libertarians left who can bear to watch the ABC were too busy trying to save the nation from nastier threats. Australia is getting millimeter wave scanners at International Airports, and if you don’t want to be scanned, you need to leave the country… by boat. (Either that or swim with the crocs across the Timor Sea.)

Body scanner blind spotWith no opt out clause, what happens when the first person facing deportation refuses to be scanned? Well that’s all right then, we’ll just book them on a cruise to Kandahar? Civil Liberties Australia was one of the few to speak up. Maybe those scanners are safe? Maybe? But at least one man with a pacemaker says Australia is off his holiday list now. Can someone find the peer reviewed research showing there are no long term effects on the unborn?

There’s also the catch that if any terrorist has a computer with an internet connection, they probably know how to get guns past the scanners.

Then a nice man named Tony wrote to me asking if I liked his graphic (below), and I did. Do admire the powerful communication tool here (it’s worth a look). The only thing it lacked was to tell us non-US folk that the TSA stood for the Transportation Security Administration.

Once upon a time it took months to get to Australia, the ships had no GPS, sometimes not even an engine, and the in-non-flight food gave you scurvy. People died, no one had travel insurance, and before WWII even a blister could kill you.

Brace yourself, how things have changed. Travel in the satellite era is so dangerous now, it takes 62,000 employees to make it safe (just in the USA). Of those, nearly 4,000 are based in the Washington DC headquarters of the TSA. The average salary of those desk-based public servants in the regulating class is … $104,000. That’s average?

Here in Australia our airport scanning scheme is supposed to cost $28 million.

Pay the TSA $100 protection money to avoid scanning and pat downs

21 March 2012 | Source | Permalink | comments: 1
By SCOTT MCCARTNEY, WSJ

Categories: [ Full Body Scanners ]

Hate the full-body scans, pat-downs and slow going at TSA airport security screening checkpoints? For $100, you can now bypass the hassle.

The Transportation Security Administration is rolling out expedited screening at big airports called "Precheck." It has special lanes for background-checked travelers, who can keep their shoes, belt and jacket on, leave laptops and liquids in carry-on bags and walk through a metal detector rather than a full-body scan. The process, now at two airlines and nine airports, is much like how screenings worked before the Sept. 11 attacks.

To qualify, frequent fliers must meet undisclosed TSA criteria and get invited in by the airlines. There is also a backdoor in. Approved travelers who are in the U.S. Customs and Border Protection's "Global Entry" program can transfer into Precheck using their Global Entry number.

"It's a completely different experience than what you're used to," said Matt Stegmeir, a platinum-level Delta Air Lines frequent flier who was invited into Precheck when it opened at his home airport, Minneapolis-St. Paul. Besides zipping through security screening quickly and easily, Mr. Stegmeir noticed another difference: TSA agents at the Precheck lane are usually smiling.

"It's really a jarring contrast. It reminds you just how much of a hassle the security procedures in place really are," he said.

Global Entry has been extremely popular with frequent international travelers. Approved travelers get to use a kiosk to enter the country rather than waiting in often-long lines to get their passports stamped and go through Customs inspection.

Consider that in January at Chicago's O'Hare International Airport, the average wait in line was 35 minutes between 4 and 5 p.m., and the longest wait was 137 minutes. The wait at Terminal 1 at New York's Kennedy International Airport averaged 44 minutes in January for people arriving between 10 and 11 a.m. Enrolling requires a $100 application fee for a background check, plus a brief interview with a Customs officer.

For domestic travel, Global Entry pays off because it gets you into Precheck. Once TSA announced in the fall that enrollment in Global Entry and CBP's other "trusted travel" programs (Nexus for frequent travel across the Canadian border and Sentri for frequent travel across the Mexican border) would get you into Precheck, applications for Global Entry took off.

In February, for example, 26,602 people applied, more than triple the number of applications in February 2011, according to CBP. And February applications were up 42% from January as more and more travelers catch on.

"We want as many people as possible in the program," said John Wagner, CBP's executive director of admissibility and passenger programs.

TSA says it also wants as many people as possible in Precheck, which is still in pilot-testing phase. Both agencies say the programs can enhance screening of people they know nothing about if they can move low-risk people who submit to background checks out of the main queues.

"We can reduce the size of the haystack when we are looking for that one-in-a-billion terrorist," said TSA Administrator John Pistole.

Mr. Pistole, an FBI veteran who took over TSA in 2010, said that by studying frequent-flier histories as well as conducting background checks, he's confident the U.S. now has the technology and the intelligence information to make less-rigorous, faster screening work. TSA has been trying to move to more "risk-based" security—something critics have suggested for many years.

Once in Precheck, TSA still checks names against terrorism watch lists before every flight, just as it does for other travelers. If a passenger is cleared for Precheck screening, a code is embedded in a traveler's boarding pass.

Stop CSG Rally video report - Government fails people of NSW

Categories: [ Coal Seam Gas ]

Truth News covers the stop CSG Rally at Parliament House NSW, 15 March 2012.

In the morning a motion was put to the NSW Upper House by Jeremy Buckingham of the Greens – to place a moratorium on all coal seam gas (CSG) projects in the state, other than the Camden production field. It was lost 16-19, with the Coalition, Shooters and Fishers and Christian Democrats against; and Labor and The Greens in favour.

In the afternoon a petition with over 20,000 signatures was presented in Parliament.

Protesters assembled outside Parliament at 4:00pm, then entered the building to continue their peaceful protest. After barely 10 minutes, the protesters were ejected from Parliament, allegedly because of the wording on their T-shirts.

Report from Stop CSG Illawarra follows:

Thursday March 15 2012 was a big day for the coal seam gas issue in our state parliament.

In the morning a motion was put to the NSW Upper House by Jeremy Buckingham of the Greens – to place a moratorium on all coal seam gas (CSG) projects in the state, other than the Camden production field. It was lost 16-19, with the Coalition, Shooters and Fishers and Christian Democrats against; and Labor and The Greens in favour.

In the afternoon it was the turn of our petition, YOUR petition, to be debated. Over 20,000 signed, calling on the Government to put in place an immediate moratorium on all CSG projects; a royal commission into the full impacts of CSG; and an immediate ban on fracking. Gareth Ward and Lee Evans spoke against, and Ryan Park and John Robertson spoke in favour. You can view the “debate” video (including its descent into chaos) in full online.

In both Houses Coalition members showed absolute contempt for the people of NSW. The Coalition called a moratorium irresponsible, saying that the Government must wait for more facts. But it is completely irresponsible to develop an industry before getting the facts.

Gareth Ward spoke against the petition – defending Coalition plans as adequate. Lee Evans spoke against the petition, then admitted to signing it. But he can’t have it both ways. He either stands with his community, and the 74% of people in NSW who support the call for a moratorium, or he tows the Coalition line and acts on behalf of the CSG industry. Yesterday, he chose the latter.

Actions speak louder than words. The Liberals opposed the petition. The Coalition voted down a moratorium. Barry O’Farrell did not even show up. CSG wells are being drilled in our drinking water catchment and the Government is not stopping it.

Yesterday, the vital role of community campaigns could not have been clearer. The Government is failing to act for the people of NSW; so we must. As the Coalition scrambles to defend the indefensible, we must launch a people’s moratorium and lock the industry out of our communities.

See you at the CSG Community Conference on Sunday March 25.

 

How Facebook is exterminating communities

Ladies and gentlemen, I have been struggling (unsuccesfully) to get the new facebook timeline features to work in a reasonable way which suit the needs of this website, and I just want to let you all know that I've had enough!

I'm mad as hell and I'm not going to take it any more!

I've come to the conclusion that the Facebook ruling elite have decided to quietly exterminate their community pages, by forcing everyone (including fan pages and groups) over to the new publishing format which gives THEM more control and YOU less control.

Of course, this is sugar coated as such draconian changes always are, with superficially "nice" features such as a wider tab and a few token settings which give you the illusion of control.

But here is the bitter pill: as an admin of the TNRA page I can no longer control what users see - this is now managed by Facebook. THEY now decide is appropriate for each of us to see, based on our friends, our "likes" and our previous browsing choices.

They call this "personalizing" our user experience.

Don't be fooled! In reality they are CONTROLLING our user experience, under the cover of tailoring our view to a vacuous commercial construct of "personal preference".

Hyper "personalization", which facebook is forcing on us, is anathema to the very essence of community, which is about shared experience. It is more in keeping with modern consumer marketing practices, which use all kinds of psychologically manipulative tactics to get people to become attached to a BRAND.

Indeed, personalization is a great way of DESTROYING communities because it forces everyone into a scenario where all interactions are mediated by "Nanny Facebook", who "personalizes" what we see based on an involuntary algorithm which determines what is best for each of us.

Folks, it is time to LEAVE Facebook!

The CSG Exploration Permit that covers Sydney

Categories: [ Coal Seam Gas ]

In 2008, the NSW government under Labor granted Dart Energy a Petroleum Exploration Licence (PEL 463) to explore for CSG across 2400sqkm of the Sydney Basin - from Gosford on the Central Coast to Coalcliff south of Sydney. The first exploration well has been approved was for the inner city Sydney suburb of St Peters. On June 2, 2011 Stop CSG-Sydney provided Dart Energy with a list of questions related directly to their plans to drill in St Peters, based on the Review of Environmental Factors. Here's the list of questions and the responses (received 64 days later).

Dart Energy agreed to meet St Peters residents at St Peters Town Hall, Tuesday 16th of August 6pm. For those that couldn't make it visit You Tube or watch the video.

CSG mining is already destroying communities across NSW and QLD, so it is crucial we act now to stop csg drilling in St Peters.

So far we have rallied together, lobbied our politicians, held community information events, hosted a community forum to hear the City of Sydney plans for trigeneration (view the City Of Sydney response to our questions), screened the US documentary Gasland, letterboxed hundreds of homes, submitted a formal submission to the NSW Government Coal and Gas Strategy and more.

Over 200,000 people live, work and play within 2km of the gas exploration site in St Peters.

ARE YOU ONE OF THEM?

Hi Josh.
FYI. I don’t have time for a debate. I’m just supplying information for your perusal.  I’m a farmer in the South Burnett. I’ve been watching the skies all my life because my existence depends on the rate of precipitation. Too much or too little is a problem.
I have been watching the development of what we call chemtrails for at least 25 years. My research tells me that they have many nasty uses and are an integral part of geoengineering which you should also check out.
We have minimal jet, and air, traffic here except for when rain is imminent. At those times, depending on the likely amount of precipitation, we get numerous jets spewing out chemtrails that expand to many times the size of what leaves the exhaust of planes. (The few times we get a passenger plane there is either no contrail or one that disperses within a minute. ) Some days there are numerous planes spewing out the stuff: 2 and 3 at a time in some instances. Recently there were so many that the sky turned metallic grey and the sun was obscured to such a point that even the unenlightened were asking what on earth was going on. The metallic grey and sun phenomenon were observed from Gympie to Biggenden.
We had a flood in the early part of last year. The next rain of any use at all was in March this year. I thought it strange that it was just the right time to get farmers in the planting mood at just the right time. My suspicions were correct: no useful follow up rain so many that planted have already realised they wasted borrowed capital.
Believe what you wish but if this rot is not stopped more and more farmers will crash and burn. The general populace will be next.
Regards
Cris

From the entry 'Contrails dissipate quickly whereas chemtrails linger?'.

The article following my comment is from http://www.truthnews.com.au chemtrails segment titled “CONTRAIL SCIENCE which I can only describe as JUNK SCIENCE. This forum gets funnier by the day, or at least by the intervals of time wherein I come back to look for new jokes. I am, as is written here, ANY PILOT, as described by the author of the “CONTRAIL SCIENCE” segment below, and also an aircraft maintenance engineer, retired. I am somewhat amused by the glider pilot, JOSH ANONYMOUS who makes feeble attempts to “correct” what I have written every now and then, but then I suppose there is always room for even more humour.
For those who obviously do not understand the mechanics of contrails, I offer the following for consideration. As is known, one tonne of fuel cannot be magically converted to 1.5 or 3.5 tonnes of water, or whatever the magic figures are that are bandied about. The water that is produced in the creation of power/thrust from turbine engine combustion, both jet and propeller types at altitude, is a clear-cut matter. The fuel that is burned CONTRIBUTES to the formation of the resultant water droplets that are borne (past participle of bear) of the combustion process and pass into the freezing air behind the aircraft to be rapidly condensed and form a contrail (condensation trail).
To believe that an aircraft carries aloft water, in its fuel supply, sufficient to produce more than the weight of the fuel on board at take-off is simply nonsensical. To understand how the water is “produced” we need look no further than an example. On a clear blue winter day, with not a cloud in the sky, with ambient conditions (humidity, temperature, wind) in the suitable range, we note that a Boeing 747 burns about (approximately) 10 tonnes/hour of fuel (aviation kerosene) in cruise (4 engines) and we consider Pratt and Whitney JT-9 engines. The amount of air that is compressed and goes through the engines (4) in one second is approximately 2,832 cubic metres (100,000 cubic feet). All figures approximate due to unknown variations in ambient conditions. This means that there are about 2,832 x 60 x 60 cubic metres of air through the four engines every hour at cruise. i.e. 1,019,520 cubic metres per hour. The aircraft travels at about 500 knots True Airspeed (mach .85). Consider humidity to be say50%, for an example only, it means that the air mass is not saturated so NO CLOUD can or will form. The aircraft gathers and compresses air at a rate of 2,832 cubic metres each second, passing it through its engines at a ratio of 23.4 to 1.
A relative humidity of 100% means that the air can’t hold any more water vapour. It’s totally saturated. When this occurs, it can rain if the temperature falls. In fact, the RELATIVE HUMIDITY MUST BE over 100% where clouds have formed for it to rain. The relative humidity MUST BE 100% for cloud to form and supersaturation, i.e. over 100% relative humidity must occur for rain to fall. However, at ground level where the rain lands, the relative humidity can be less than 100%. So, at 50% humidity, there is no possibility of cloud forming, and all the water in the atmospheric air that is compressed and put through the can (the annular combustion chamber) will be instantly boiled, turned to steam and passed through the can and out the exhaust. Water does not burn, it simply changes state from liquid to gas, then back to liquid after being exhausted. As the water vapour reaches the outside freezing air it is immediately condensed and is seen as a contrail which is just condensation, hence the name “condensation trail”.

Now we begin to realise that on this clear day, with no cloud about, the exhausted condensation can only cool to the temperature of the surrounding atmosphere, and the water vapour will be absorbed by the surrounding drier air. Considering that that aircraft is surrounded by many cubic kilometres of drier air, we can see that here is no chance that the condensation can cause the surrounding air to become 100% saturated and form cloud. To claim so would be to say that, as an example, we could throw a bucket of ice cubes into an Olympic swimming pool and expect the ice cubes to freeze the surrounding water, or throw a bucket of boiling water into a similar swimming pool and expect the surrounding water to boil or even at least heat a little. Sorry, but absorption into the surrounds is what controls events. If the story of enduring contrails had any legs, we would have no need to spend fortunes, as we have over many decades, with attempts to seed cloud and make rain, we would just need to fly large aeroplanes around and around through clouds, or anywhere at all and even make it rain over deserts.

The claims that contrails “spread” out and form cloud are just plain, good old-fashioned bullshit spread by ignorant people.
If anybody knows any of the laws of thermodynamics that contradict what I have written here, please proffer it as I will be fascinated to see. C P Snow made the only real sensible comment about the laws of thermodynamics when he said that the first law tells you that you can’t win, and the second tells you that you can’t even break even.

And by the way, for the information of the author of the “CONTRAIL SCIENCE” there is NO solar heating of the atmosphere, as all heat rises from the ground after the sun’s heat passes through the atmosphere to the ground.

From http://www.truthnews.com.au
CONTRAIL SCIENCE
  For a contrail to form, suitable conditions must occur immediately behind a jet engine in the expanding engine exhaust plume. A contrail will form if, as the exhaust gases cool and mix with surrounding air, the humidity becomes high enough (or, equivalently, the air temperature becomes low enough) for liquid water to condense on particles and form liquid droplets. If the local air is cold enough, these newly formed droplets then freeze and form ice particles that make up a contrail.
  Because the basic processes are very well understood, contrail formation for a given aircraft flight can be accurately predicted if atmospheric temperature and humidity conditions are known.
  After the initial formation of ice, a contrail evolves in one of two ways. If the humidity is low, the contrail will be short-lived. Newly formed ice particles will quickly evaporate. The resulting contrail will extend only a short distance behind the aircraft. If the humidity is high, the contrail will be persistent. Newly formed ice particles will continue to grow in size by taking water from the surrounding atmosphere. The resulting line-shaped contrail extends for large distances behind an aircraft. Persistent contrails can last for hours while growing to several kilometers (spelling kilometres) in width and 200 to 400 meters in height. Contrails spread because of air turbulence created by the passage of aircraft, differences in wind speed along the flight track, and possibly through effects of solar heating.
  Thus, the surrounding atmosphere’s conditions determine to a large extent whether or not a contrail will form after an aircraft’s passage, and how it evolves. Other factors that influence contrail formation include engine fuel efficiency, which affects the amount of heat and water emitted in the exhaust plume.

TNRA is informed by science and is not interested in propping up anyone’s belief systems, and we don’t apologise for that.
But, please, don’t take it from me, speak to any meteorologist or ANY PILOT and they’ll tell you straight, that there is HUGE variation in the length and persistence of contrails. Sometimes they don’t form at all, other times they form, but dissipate quickly, other times they persist and spread out.
That’s the facts folks, and it’s been that way since planes first went up in the sky.
If you believe otherwise, I’m afraid you’ve been conned.
Forgive me if I seem rude or impatient on this topic, but every few months I come across a new wave of people who have been subjected to the same false propaganda about chemtrails, and I have to run the same arguments and cite the same articles over and over again. It does wear one’s patience down.
Before making some kind of angry reply, I urge you to read this article and associated links. It’s fairly detailed, and deals with most of the usual claims made by chemtrail alarmists.
Finally, let me qualify all this by saying that I do not doubt that geo-engineering programs exist, and that, indeed, some of the patented techniques discussed at international forums include the creation of artificial cirrus cloud.
