Bringing penny stock egghead review
concept of an â€œartificial leafâ€ google sniper review
to reality, a team of researchers at MIT has
published a detailed analysis of all the factors that could limit the efficiency of such a system. The new analysis lays out a
roadmap for a research program to improve the
these systems, and could quickly lead to the production of a practical, inexpensive and commercially viable prototype.Such a system would use sunlight to produce a storable fuel, such as hydrogen, instead of electricity for immediate use.
This fuel could then be used
on demand to generate electricity through a
fuel cell or other
device. This process
solar energy for use when the sun isnâ€™t shining, and open up a host of potential new applications.The
new work is described in a paper this week in the
Proceedings of the National Academy of Sciences by associate professor of mechanical engineering Tonio Buonassisi, former MIT professor Daniel Nocera (now at Harvard University), MIT postdoc Mark Winkler (now at IBM) and former MIT graduate
student Casandra Cox (now at Harvard). It follows up on 2011 research that produced a â€œproof of conceptâ€ of an artificial
leaf â€” a small
device that, when placed in a container of water and exposed to
sunlight, would produce bubbles of hydrogen and oxygen.The
device combines two technologies: a standard silicon solar cell, which converts sunlight into electricity, and chemical catalysts applied to each side
of the cell. Together, these
would create an electrochemical device that uses an
electric current to split atoms of hydrogen and oxygen from the water molecules surrounding them.The
goal is to
produce an inexpensive, self-contained system that could be built
from abundant materials. Nocera
has long advocated such devices as a means of bringing electricity to billions of people, mostly in the developing world,
who now have
little or no access to it.â€œWhatâ€™s
significant is that this paper really describes all this technology that is known, and what to expect if we put it all together,â€ Cox says.
â€œIt points out all the challenges, and then you can experimentally address
each challenge separately.â€Winkler adds
that this is a â€œpretty robust analysis that looked at whatâ€™s the best you could do with market-ready technology.â€The
original demonstration leaf,
in 2011, had low efficiencies, converting less than 4.7
of sunlight into fuel, Buonassisi says. But the teamâ€™s new analysis shows that efficiencies of
16 percent or more should now be possible
using single-bandgap semiconductors, such as crystalline silicon.â€œWe were
surprised, actually,â€ Winkler says: Conventional wisdom held that the characteristics of silicon solar cells would severely limit their
effectiveness in splitting water, but that turned out not to be the case. â€œYouâ€™ve
just got to
question the conventional wisdom sometimes,â€ he says.The
obtaining high solar-to-fuel efficiencies is to combine the right
and catalyst â€” a matchmaking activity best
guided by a roadmap. The approach presented by the team
allows for each component of the artificial leaf to
be tested individually, then combined.The voltage produced by a standard silicon solar cell,
volts, is insufficient to power the water-splitting reaction, which needs more than 1.2
volts. One solution is to pair multiple solar cells in series.
While this leads to
some losses at the interface between the cells, it is a promising direction for the research, Buonassisi says. An additional source of inefficiency
is the water itself â€” the pathway that the electrons must traverse to complete
the electrical circuit â€”
which has resistance to the electrons, Buonassisi says.
So another way to improve efficiency would be to lower that resistance, perhaps by reducing the distance that ions must travel through the liquid.â€œThe solution
is challenging,â€ Cox
says. But, she adds, there are â€œsome tricksâ€ that might help to reduce that resistance, such as reducing the distance between the two sides of the reaction
by using interleaved plates.â€œIn
simulations, we have a framework
to determine the limits of efficiencyâ€ that are possible with such a system, Buonassisi
says. For a system based on
conventional silicon solar cells, he says,
that limit is about 16 percent;
for gallium arsenide cells, a widely touted alternative, the limit rises to 18 percent.Models to determine the theoretical limits of a given system often lead researchers to pursue the development of
new systems that approach those limits, Buonassisi says. â€œItâ€™s usually from these kinds of models that someone gets the courage to go ahead and make the improvements,â€ he says.â€œSome of the most impactful papers are
ones that identify a performance limit,â€ Buonassisi says.
But, he adds, thereâ€™s a â€œdose of humilityâ€ in looking back at some earlier projections
for the limits of solar-cell efficiency: Some of those
predicted â€œlimitsâ€ have already been exceeded, he says.
â€œWe donâ€™t always get it right,â€ Buonassisi says, but such an analysis â€œlays a roadmap for development and identifies a few â€˜leversâ€™ that can be worked on.â€James Barber, the Ernst
Chain Professor of Biochemistry at
Imperial College London,
who was not connected with this work, says, â€œIt is generally agreed
that for an
effective technology to emerge,
the efficiency of the device
must be 10 percent or
more.â€ The MIT teamâ€™s
work suggests such devices â€œcan provide efficiencies as high as 15 percent.
This level of energy conversion is considered very good and
practical.â€Barber adds that a next step, demonstrating these improvements in a functioning device, is crucial: â€œIt is very important to construct a working system which has a large
surface area and operates with solar energy under open
for a long period of time, as is done with the testing of solar cells.â€
If this can be achieved,
he says, â€œthe construction of
robust and efficient
solar-driven modules which produce hydrogen from water
on a large industrial scale would have considerable impact on human society.â€The
work was supported by the National Science Foundation, the Air Force Office of Scientific Research, the Singapore National
Research Foundation through the Singapore-MIT
Alliance for Research and
Technology, and the
Chesonis Family Foundation.

using Java exploits signed with digital certificates to trick users into allowing the malicious code to run inside browsers. Many new computers should come with
a version of the usual consumer warning:
Some recommended reading to learn more about the search for the Higgs boson. To understand how an electrically powered system might waste little energy while running, the researchers first looked at general sources of energy loss in running robots.
They found that most wasted energy comes from three
sources: heat given off by a motor; energy dissipated through mechanical transmission, such as losses to friction through multiple gear trains; and
such as energy
lost through a heavy-footed step, as opposed
to a smoother and more gentle gait. The group then came up with design principles to
minimize such energy waste. To combat heat loss
from motors, the group proposed a high-torque-density motor â€” a motor that produces a significant amount of torque
given weight and heat production.
The team analyzed the relationship
between motor size and torque, and designed custom motors that
exceed the torque performance of commercially
available electric motors.Â The team
found that such high-torque motors require fewer gears â€” a characteristic that would improve efficiency even more, as there would be less machinery through which energy could dissipate.
Many researchers have used springs and dampers in series with motors to protect the
robot from forceful impacts during locomotion, but itâ€™s difficult to control a springâ€™s stiffness and damping ratio â€” which can be a problem if a robot has to traverse disparate surfaces, such as asphalt and sand.Â
â€œWith our system, we can make
our robotic leg behave like a spring or damper without having physical springs, dampers or force sensors,â€ Kim says.

Europe: Frank Abagnale, portrayed penny stock egghead
Me if You Can, and now an FBI security expert, warns of danger to childrenFrank Abagnale, the
man dubbed the world's greatest conman,
has issued a stark warning about the dangers of identity theft and children using Facebook.Abagnale,
by Leonardo DiCaprio in Steven Spielberg's film Catch Me If You Can, said that children in
particular need to be made aware of the serious risks of unwittingly revealing information
on social networking sites.He
has nearly 40 years experience as a security
expert for US law enforcement agencies, having switched sides when he was eventually caught by the FBI
after spending half his teenage years on the run as
a confidence trickster, imposter,
cheque forger and escape artist in the 1960s."I'm not on it [Facebook,
but] I have no problem with it," he said, addressing the Advertising Week Europe conference in London on Wednesday. "I have three sons on it.
understand why people like it.
But like every technology you have
to teach children, it is an
society to teach them
use it carefully."He said having
accrued 37 years' work with the FBI he
has also become aware of many widely available techniques to gather dangerous amounts of personal data from Facebook.He
gave the example of a creeper virus that allows the tracking of a Facebook
user even if their phone
is not transmitting.Another
programme, which Abagnale said is owned by
Google, uses facial recognition that can match an individual with their
personal information on the social networking website "in just
you tell me your date of birth and where you're born [on Facebook] I'm 98% [of the
way] to stealing your identity," he said.
"Never state your date of birth and where you were born [on personal profiles],
otherwise you are saying 'come and steal my identity'."He also advised Facebook users to never choose a passport-style
a profile picture, and instead use group photographs.Abagnale, who uses a document shredder so he knows that even the FBI cannot reassemble the paper, also warned about the dangers of the seemingly innocuous details given away by users who "like" Facebook postings."What [people] say on a Facebook page stays with them,"
"Every time you say you
'like' or 'don't like' you are telling someone [things like] your sexual orientation, ethnic background, voting record."He
said he has a "tremendous amount of respect" for the UK's privacy
laws, which are "way ahead" of
said that while it
was common to see companies such as Facebook being criticised for privacy issues in the media, it is up to people to take action to keep
their data private."Your
privacy is the only thing you have left," he said. "Don't blame
all the other companies â€“ Google, Facebook â€“ you control it.
You have to
keep control of your own information."Between the ages of 16 and 21 Abagnale claims to have impersonated airline pilots, a doctor and a lawyer while forging and cashing $2.5m
in cheques and employing other confidence scams.
However, he has admitted in the past that his co-writer
on the book Catch Me If You Can,
on which the DiCaprio film was based, "over
dramatised and exaggerated" some of his exploits.The
64-year-old, who said he has voluntarily paid back every penny he gained illegally, added that airline
Pan Am estimates he flew more than a million miles for free on 250 aircraft to 26 countries during his teenage crime spree.He said that counter-intuitively the rise of technology has made it harder, not easier, for law enforcement.
"What I did 40 years ago as a teenage boy is 4,000 times easier now," he said. "Technology breeds crime."He gave the example of creating a fake British Airways cheque
which in his
time required finding a
$1m printing press the size
auditorium and three
operators. He managed this himself with scaffolding."Today
a laptop," he
said. "Each time we add technology it makes it a little easier for criminals. I would have thought
technology would have made it harder to do what I did."He also lamented
the rise of an iPhone generation of children who have come to rely on technology and have lost the ability
to be resourceful in a more traditional way."It
is unfortunate today that many young children are not resourceful," he said.
"If you took a child in London and took their iPhone and took them somewhere else in the
country they'd probably
not be able to find
their way back. That's a shame."He added that he avoids the trappings of fame â€“ books, a current TV series, a broadway musical and dozens of offers to
front shows and make guest appearances â€“ and has perhaps surprisingly not benefited from
or fees due to
restrictions of his FBI contract.Abagnale
said he had "nothing to do
with the film Catch Me If You
Can but was happy Steven Spielberg recreated a relatively realistic version of his life, despite some factual errors. His father, portrayed in the film by Christopher Walken, in fact died

If I had been
brilliant or a
genius I wouldn't have needed to break the law just to survive.
I've had to live with it the rest of my life".Abagnale said he has turned down three
pardons from three different US presidents."I
do not believe, nor will ever believe a piece of paper
will excuse my actions.
Only my actions will."â€¢ To contact the MediaGuardian news desk email email@example.com or phone

trait which is seen
as emblematic of the artistic inferiority of cinema as compared with other, older art

Is it practical to install a generator to supply emergency power to

the American Southwest to the Middle East, water is a highly contested resource: Many neighboring nations, and several states
in the United States, have fought decades-long battles to control water supplies.
And that need for water only seems likely to increase.Â â€œOut in the world, thereâ€™s
growing demand for fresh water, especially where there
is urban development,â€ says Larry Susskind,
Professor of Urban and Environmental
Planning in MITâ€™s Department of Urban Studies and Planning.
â€œAt the same time, climate change is altering
in unexpected ways how much
water there is.
So you have increasing pressures on
and thus battles over how water will be allocated.â€
these disputes seem extremely
difficult to solve.
How, for example, can Israel and its neighbors
share scarce water supplies? How can there be
enough water to supply both populous Southern California and fast-growing Arizona? Such problems are virtually intractable, right? Wrong, according to Susskind.â€œWater
is not most usefully thought of as a scarce resource,â€
â€œItâ€™s a flexible resource. Itâ€™s not that thereâ€™s not
enough water. Itâ€™s that we waste it and donâ€™t invest in the technologies that would allow us to make more efficient uses of it.
If you keep thinking water is a scarce resource, you
will be locked into battles you donâ€™t need to be locked into.â€That notion is central to what Susskind calls
â€œa new approach to water managementâ€ in a new book on the subject, Water Diplomacy, co-authored with civil engineering professor Shafiqul Islam of Tufts University and published this month by Resources For the Future, in affiliation with Routledge.
In the book, Susskind and Islam argue that nations and their leaders need more pragmatic
and flexible ways of solving water-supply problems,
and offer a new paradigm
for approaching these
issues, which they call the Water Diplomacy Framework (WDF).
Their aim, Susskind asserts, is nothing less than to â€œcompletely change the nature of the conversation among people using the same water resources.â€â€˜If
you think in zero-sum terms, you will only produce zero-sum solutionsâ€™How? For one thing, the authors assert,
water supply is
not just a
technical or engineering problem,
but must be addressed with an eye to political realities. Indeed, both
of the bookâ€™s authors have deep backgrounds in diplomacy and negotiating: Susskind is a vice chair of the Program for Negotiation at Harvard Law School, while Islam is the Bernard M. Gordon Senior Faculty
Fellow in Engineering, and professor of water diplomacy at the Tuftsâ€™ Fletcher School of Law and Diplomacy.Â
Water Diplomacy digs into a
series of water-resource
disputes, in chapters co-written with several graduate
lays out the specific principles that Susskind and Islam believe must be interjected
into the future of water management.
Thinking of water as a â€œflexible resource,â€
for instance, encourages officials, citizens and other stakeholders to think of ways to conserve or reuse water so the same supply
can address greater demand.
Similarly, Susskind says, â€œwater management means dealing with open systems, or water networks, rather than closed systems.â€ By that,
too often water management consists of â€œdrawing a line around a watershed,
a river, some body of water,â€ and then divvying up that supply, rather
than thinking of all the factors that can affect regional supply and demand. In practice, taking a new approach means
finding technologies that allow different
political entities to use share water more effectively. In the Southwest, where the Colorado River
essential source of water, New Mexico and Arizona have
helped pay for conservation measures
in California that allow
for more water to be
diverted to those smaller states. In the Middle East, Israel
and Jordan have a long-running agreement about managing the Jordan River:
Israel stores water in wet seasons, and
both countries look for new ways to manage the supply and demand. Israel, Susskind notes, is also looking for ways to increase its use of desalination plants that could expand the regional supply of water. â€œThat agreement has stood the test of time, even though
relationships in the region are
tough,â€ Susskind says. Such programs underscore a third principle that Susskind and Islam emphasize. â€œIf you
think in zero-sum terms, you will
only produce zero-sum solutions,â€ Susskind says. â€œWe think
there are value-creating opportunities, non-zero-sum outcomes.â€Talking it throughThat is why politics, not just engineering, is such an important part of
water management, the authors
believe.â€œGiven the scientific complexity, getting a decision
with lots of parties means engaging people in something other than shouting matches at public hearings,â€ Susskind says.
means facilitating a
with a lot
of people at the table.
We know how to do that in other arenas,
but we havenâ€™t been committed to doing that in the water arena until relatively recently.â€A success story
in this vein, Susskind and Islam
believe, is Californiaâ€™s CALFED program,
which over many years has worked out arrangements for sharing water from Northern Californiaâ€™s Sacramento River delta with cities and the agricultural Central Valley. CALFED links dozens of government agencies with scientists, engineers and water consumers to
map out policy. â€œIt was the engagement
of all those parties
that made it
possible to produce not only an ingenious agreement that reflected a deep
understanding of the water systems involved, but also political
credibility to the negotiated outcome, because all the people who would have to have a say about it were involved in producing a decision,â€
Other scholars in the field agree that new perspectives on
water use are badly
â€œWhatâ€™s innovative about this approach
is that it explicitly attempts to include scientific input
[along with] a good political process
of decision making, which is just as important as any particular
decision being made,â€ says William Moomaw, a professor of international environmental policy at Tufts Universityâ€™s Fletcher School of Law and Diplomacy who has taught classes with Susskind and Islam.
As for why countries would be willing to try new approaches, Moomaw says, â€œweâ€™re stuck.
We canâ€™t go any further
with the approach that weâ€™ve had.â€
For their part, Susskind and Islam are attempting to convey the importance of those principles to interested parties worldwide. The book grew out of annual water-diplomacy workshops
they host at MIT each summer, funded by the National Science Foundation,
which so far have attracted officials
from 22 countries. The
workshops are part of the MIT Science Impact
Collaborative, a part
of the Department of Urban Studies
Moreover, making water
available to everyone in the future, they emphasize, will require input from
scholars in all disciplines, from science and engineering
to the social sciences and humanities. â€œA great many problems
in the world that MIT students and faculty want to
work on exist at the junction of science, policy and politics,â€ Susskind says. Scholars, he adds, should
to learn how their colleagues
in other fields work and think. You cannot succeed in solving the problems in the world unless and
until you can put these collaborative efforts
together.â€ Q. We need to replace our water heater and are thinking of

Elaine Bennett Research PrizePrize recognizes outstanding young women in economics Anna Mikusheva, the Castle Krob Career Development Assistant Professor of Economics, has been awarded the 2012 Elaine Bennett Research Prize
from the American Economic Association's Committee on the Status of Women in the Economics Profession (CSWEP).
The prize, conferred every
other year to recognize, support and encourage outstanding contributions by young women in economics, was awarded to
Mikusheva for advancing the field of econometric theory. Mikusheva's research combines
econometric theory with tools for tackling problems in applied econometric practices.
She joins two previous Bennett award winners from MIT: Esther Duflo, the Abdul Latif Jameel Professor of Poverty
and Development Economics; and Amy Finkelstein, Ford Professor
of Economics. "Anna has done outstanding research on empirical methods for macroeconomic data," said Whitney Newey, the Carlton Professor of Economics and head of the Department of Economics. "She solved longstanding problems of inference for non-stationary data and for modern macroeconomic models. She is also an outstanding teacher. This prize is a wonderful recognition of a promising scholar." Full story at MIT SHASS News

When beams of particles crash into each other at
high speeds, the collisions yield hundreds of new particles,
most of which fly away from the collision point at
close to the
speed of light. However, the Compact Muon Solenoid (CMS) team at the LHC found that in a
sample of 2 million lead-proton collisions, some pairs of particles flew away from each other with their respective directions correlated. â€œSomehow they fly at the same
direction even though it's not clear how they can communicate their direction with one another. That has surprised many people, including us,â€ says MIT physics professor Gunther Roland, whose group

findings will appear in
an upcoming issue of the journal Physical Review B and is now

heavy-ion group, which includes Roland and MIT physics professors Bolek Wyslouch and Wit Busza,
saw the same distinctive pattern in proton-proton collisions about two years ago. The same flight pattern is also seen when ions of lead or other
heavy metals, such as gold and copper, collide with
each other. Those heavy-ion collisions produce a wave of quark
gluon plasma, the hot soup
of particles that existed for
the first few millionths of a second after
the Big Bang. In the collider, this wave sweeps some of the resulting particles
in the same direction, accounting for the correlation in
their flight paths. It has been theorized that
collisions may produce a liquid-like wave of gluons, known as color-glass condensate.
This dense swarm
of gluons may also produce the unusual collision pattern seen in proton-lead collisions, says Raju Venugopalan, a senior scientist at Brookhaven National Laboratory, who was not involved in the current research. Venugopalan and his former postdoc Kevin Dusling theorized the existence of color-glass condensate shortly before the particle direction correlation was seen in proton-proton collisions.
While protons at normal energy levels consist of three quarks, they tend to gain an accompanying cluster of gluons at higher energy levels.
These gluons exist as both particles and waves, and their wave functions can be correlated
with each other. This â€œquantum
entanglementâ€ explains how the particles that fly away from the collision can share information such as direction of
path, Venugopalan says. The correlation is â€œa very tiny effect, but itâ€™s pointing to
something very fundamental about how quarks and gluons are arranged spatially within a
researchers originally set out to use the lead-proton collisions as a
for comparison with lead-lead collisions. â€œYou don't expect quark gluon plasma effectsâ€ with lead-proton collisions, Roland says. â€œIt was supposed to be sort of a reference run â€” a run in which you can study background effects and then subtract them from the effects that you see in lead-lead collisions.â€
That run lasted only four hours, but in January, the CMS collaboration
plans to do several weeks of
which should allow them to establish whether the
collisions really are producing a liquid, Roland says. This should
help narrow down the possible explanations and determine if the effects
seen in proton-proton, lead-proton and lead-lead collisions are related.

traditional acoustic instruments warm and distinctive sounds, while the power of
modern electronic processing provides an unlimited degree of control to manipulate the characteristics of an instrument's sound. Now, a guitar built by a student at MIT's Media Lab promises to provide the best of both worlds. The Chameleon Guitar â€” so named for its ability to
mimic different instruments â€” is an electric guitar
whose body has a separate central section that is removable. This inserted section, the
soundboard, can be switched with one made of a different kind of wood, or with a different structural support system, or with one made of a
different material altogether.
Then, the sound generated by the electronic pickups on that board can be manipulated by a computer
to produce the effect of a
different size or shape
of the resonating chamber.
Its creator, Media Lab master's student Amit Zoran, explains that each piece of wood is unique and
will behave in a different
way when it is part of an instrument and begins to
vibrate in response to the strings attached to it. Computers can't model all the details of that
unique responsiveness, he
So, as he began experimenting with the design of this new instrument, he wondered "what would happen if you could plug in acoustic information,
like we do with digital information on a memory stick?" Under the direction of
Media Lab Associate Professor Pattie Maes,
and with help from experienced instrument
he built the first proof of concept version
removable wooden inserts. The concept worked,
went on to build a more polished version
easier quick-change mechanism for switching the inserts, so that a musician could easily change the sound of the
instrument during the course of a concert â€” providing a variety of sound characteristics, but always leaving the same body, neck and frets so that the instrument always feels the same. With Coppiardi's help, he selected spruce and cedar for the initial soundboard inserts. This January, he demonstrated
the new instrument at the annual
Consumer Electronics Show in Las Vegas, where it received an enthusiastic response. He also demonstrated the earlier version at two electronics conferences last year.
The five electronic pickups on the soundboard provide detailed information about the wood's acoustic response to the vibration of the strings. This information is then processed by the computer to simulate different shapes and sizes of the
resonating chamber. "The original signal is not synthetic,
it's acoustic," Zoran says. "Then we can simulate different shapes, or a bigger instrument."
The guitar can even be made to simulate shapes that would be impossible to build physically.
"We can make a guitar the size of a mountain," he says.
Or the size of a mouse. Because the actual soundboard is small and
inexpensive, compared to the larger size and intricate
to build a whole acoustic instrument, it will allow for
a lot of freedom to experiment, he says. "It's small,
it's cheap, you can
take risks," he says. For example, he has a piece of spruce from an old bridge in Vermont, more than 150 years
that he plans to
use to make another soundboard. The wooden beam is too narrow to use to make a whole guitar, but big enough to try out for the Chameleon Guitar. The individual characteristics of a given piece of wood â€” what
Zoran refers to as the "romantic
value" of the material,
"is very important for the
player," he says, and helps to give an individual instrument
a particular, unique sound. Digital processing provides an infinite range
of variety. "Now," he says, "it's possible to have the advantages of both." For now, Zoran is concentrating on developing the guitar as a
thesis project for
his master's degree, and hopes to continue working on it as his doctoral thesis project. After that, he says, he hopes it will develop into a commercial product.

PC Joseph Harrington is accused of trying to 'smear' accuser as he tells court teenager
policeA Metropolitan police officer who allegedly stamped on an arrested teenager, leaving him struggling to breathe, has been accused of trying to "smear" the youth as he denied the charges.Prosecutors
claim PC Joseph
Harrington, 29, assaulted the boy, then 15, while he was being held in custody days after riots swept the country in 2011.On Wednesday he insisted he restrained the boy only after
he became aggressive and suggested the youngster had a history of making false allegations.Harrington said the youth, who
cannot be named for legal reasons, left him in "fear" for his safety during a heated confrontation in a caged cell at Forest Gate police station.The
teenager has told the court how an officer stamped on him then "dropped his whole
body" on to
his back after apparently recognising him from a confrontation a day or two before.On that occasion, he claims, Harrington put his hands around his neck.Southwark
court has heard how the teenager was arrested for a separate matter on 11 August and was taken from Stratford police station, east
London, to Forest
Gate police station.He was in the caged area near the
suite when Harrington walked in and made reference
to their previous meeting.The 17-year-old said: "I laughed
I thought: 'I'm already arrested for

Harrington allegedly stamped on his
back, he told the court.Giving
his defence, Harrington dismissed suggestions that he unnecessarily resorted to force."I was sticking to my training and what my
experience told me I needed to do," he said. He told the court officers had endured a "very tiring" few days
during the riots, when police were subjected to days of abuse.Duncan Atkinson,
prosecuting, said: "Quite
simply, Mr Harrington, you had had enough."The
officer replied: "No, I disagree, sir."Atkinson added: "He posed no
threat to anyone."Harrington
replied: "Absolutely not, he put me in fear of being immediately assaulted."He
said the teenager was known for assaulting police and told the court he believed the youth was also
known to have made false allegations.Atkinson said: "Is that something you have just thought up?"He replied: "No sir."The
prosecutor said: "Are you trying, in any way you can, to smear [him]?""No sir," Harrington replied.Harrington,
of Walthamstow, east London, denies assault. The trial was

|long-term side effect involving smoking pot
Pot addiction is illness, its lots of great quit doing the work, it is good number of most important of those. how the way we tried to stop smoking weed how I quit smoking weed
There are several real benefits to stop smoking weed, the very first in which is vitality. As i smoked marijuana for an extended time of their time it turned out very hard to me just to get off the bed in the am. Every day it took a little time for me a pair of hours and couple coffees simply to get things going and also first hours at work We felt so despondent, I didn't wont to control people Playing sports whenever you smoke pot is like driving with one feet on the foot brake and one within the natural gas. It doesn't aid in ambitions inside you should work extra hard to be capable of come up with the rest of the country. how I quit smoking weed
It can affect your own personal appearance too Hefty weed smokers stick out inside crowd There's few conditions, but major regular people who smoke , do change allot. Just how smokers communicate, the color of generally there face, nervousness and tiered appear it is all change over several years of frequent use of weed. Persons treat us in different ways when we smoke, whether or not they mean to be able to not really. Once i stopped using tobacco weed my appearance changed and my cheeks delivered to their usual color, inside the first week that I quit smoking weed a non smoker as well as a smoker pal commented on what my body had gone away and much healthier I searched.
That have been advised and written 1000 times on how marijuana impact smokers wellness. We must face that: weed and also tobacco are poison which is what they are. To the point where individuals wake up in the morning coughing up phloem and also spitting it from the submerge. Even now they disregard the signs and also continue to fumes until they comprehend how unhealthy they have come to be. I am not pointing often the finger at any individual, I've performed precisely the same. On the other hand I noticed that you need to adjust until its too late. No later than this leave decades longer at this point, because My spouse and i decide to modify and stop.
