Watching the television last  week, I came close to tears several 
times. Seeing the victims of Israel’s  indiscriminate bombing in Gaza 
was almost too much to watch. But watch I did.  Not as some ghoulish 
entertainment. No, I watched as a witness. I watched just  as my parents
 before me watched the horrific images of the death camps, evidence  of 
the Nazi genocide of Jews, the disabled, gypsies and homosexuals some 67
  years ago. And just as my parents will never deny the atrocities of 
Nazi  Germany, I will never deny the same by the Israeli government. 
I
 do not  pretend to completely understand the 5000 year history of 
Mideast. To  characterize it as complex is such a vast understatement, 
it is disingenuous. I  do know from world history classes, biblical 
study (both Jewish and Christian),  wading into the Holy Qur’an and just
 reading a newspaper over the past fifty  some odd years, it is a region
 which has been locked in constant turmoil.  Honoring the sixth 
commandment seems to have gone out the window (“Thou shalt  not kill”). I
 remember going to 6th grade camp in 1967 and coming home to find  
Israel had been attacked by Egypt, et al. and kicked the proverbial crap
 out of  Egypt, et al., in the time it took me learn how to make plaster
 molds of bobcat  footprints and leaf prints. The regional well from 
which violence and terror is  drawn seems bottomless, and none can claim
 they have not chosen to quench their  thirst from the same source. 
Over
 the years, I have met and become  friends and colleagues with anyone of
 a number of people from the region. And  just like the Irish of my 
ancestry and their take on the “troubles,” if you ask  anyone from the 
Mideast, each will have a different perspective and reason why  there is
 so much conflict in the area.We specialize in howo concrete mixer, 
But
  this I know. In 1948, the United Nations, led by the United States, 
created the  Jewish State of Israel. Perhaps the catalyst was guilt for 
standing by while 6  million Jews were slaughtered at the hands of some 
of the most diabolic people  who ever lived. Perhaps it was some 
far-sighted political move to secure a  foothold in the region. Whatever
 the reason, however, I believe it was the right  thing to do. What I do
 not think was right was to displace several hundred  thousand 
Palestinians and put them in Gaza and the West Bank, without  
designating them a state as well. Three million people in to 
geographically  separate areas and given no status.We are pleased to 
offer the following list of  professional mold maker and casters. True men, women and children without a country. 
A
 couple of  years ago, I attended Restorative Practices conference in 
Vancouver, B.C. I had  been asked to chair a session, and I agreed. 
Unbeknownst to me, it was a  teenager presentation,A specialized 
manufacturer and supplier of dry cabinet,
 a two hour  teenager presentation. The dread of monitoring teenagers 
for two hours was  swiftly washed away. The presentation was a project 
started by teens in the  Vancouver area, called Peace It Together 
(checkout the website  Peaceittogether.ca). The Canadian teens invited 
several Israeli and Palestinian  high school aged students to come and 
spend two week on Bowen Island. During the  two weeks, the students 
created short films addressing the conflict in the  Mideast. The 
metamorphosis from “enemies” to friends was heartwarming and  
encouraging. Peace is possible, just give it a chance. 
So last 
Thursday,  delegates to the United Nations voted overwhelming (133-9) to
 make Palestine a  non-member observer state. Admittedly, I am not up on
 my U.N. process and  procedure, but from what I have been able to 
gather, it is the first step toward  full Palestinian statehood. There 
must have been dancing in the streets of Gaza  and the West Bank, but 
apparently President Obama’s lunch with Mitt Romney was a  much more 
important event…and after all dancing in the street is not as  
newsworthy bombing a city back to the stone age, with weapons made in 
USA.  Regardless, what the U.N. did was a long overdue good thing. 
But
 as with  every good thing, there is always a downside. And this is a 
shameful thing.  Understandably, Israel did not vote in favor of the 
resolution. It is much  easier to oppress people who have little to no 
recognition on the world stage.  Just to prove their disdain toward 
world opinion and unbridled hatred of the  Palestinians, the following 
day, the Israeli government approved more  settlements in the occupied 
West Bank. But this was expected, not shameful. No,  it was United 
States who acted shamefully, voting against this small first step.  I 
have yet to find the legitimate reason, perhaps over the next few days 
someone  from the White House will tell us why. I, for one, am not 
holding my breath. I  am, however, ashamed. 
This nation of ours 
has no problem wading into a  country which either pisses us off or has 
something we want. We are everything  we hate; military and economic 
imperialists. When it comes to humanitarian  intervention, we just turn 
our collective backs and cover our ears. We were one  of the last to 
jump on the embargo bus against South Africa’s Apartheid  government. We
 shamefully turned our backs on the genocide of the Tutsi people  in 
Rwanda. We ran with a tail tucked between our legs at the first set back
 in  Somalia, and to this day, starvation takes more and more lives. 
Would
 it  have been so bad just this once to stand up and say, “Yes, 3 
million  Palestinians have the human right to have a state and proper 
representation in  world affairs.” It would have been right. It would 
have been just. And today, we  could have held our heads just as high as
 the days when we defeated the Nazis  and led the vote which granted 
Israel statehood. But for now, I am ashamed.  
Rather than liquid
 metal, it is a hydrogel, a mesh of organic molecules  with many small 
empty spaces that can absorb water like a sponge. It qualifies  as a 
"metamaterial" with properties not found in nature and may be the first 
 organic metamaterial with mechanical meta-properties. 
Hydrogels
 have  already been considered for use in drug delivery -- the spaces 
can be filled  with drugs that release slowly as the gel biodegrades -- 
and as frameworks for  tissue rebuilding. The ability to form a gel into
 a desired shape further  expands the possibilities. For example,High 
quality stone mosaic tiles. a drug-infused gel  could be formed to exactly fit the space inside a wound. 
Dan
 Luo,  professor of biological and environmental engineering, and 
colleagues describe  their creation in the Dec. 2 issue of the journal 
Nature Nanotechnology.  
The new hydrogel is made of synthetic 
DNA. In addition to being the  stuff genes are made of, DNA can serve as
 a building block for self-assembling  materials. Single strands of DNA 
will lock onto other single stands that have  complementary coding, like
 tiny organic Legos. By synthesizing DNA with  carefully arranged 
complementary sections Luo's research team previously created  short 
stands that link into shapes such as crosses or Y's, which in turn join 
at  the ends to form meshlike structures to form the first successful 
all-DNA  hydrogel.Find detailed product information for Low price howo tipper
 truck and other  products. Trying a new approach, they mixed synthetic 
DNA with enzymes that  cause DNA to self-replicate and to extend itself 
into long chains, to make a  hydrogel without DNA linkages. 
"During
 this process they entangle, and  the entanglement produces a 3-D 
network," Luo explained. But the result was not  what they expected: The
 hydrogel they made flows like a liquid, but when placed  in water 
returns to the shape of the container in which it was formed.  
Examination
 under an electron microscope shows that the material is made  up of a 
mass of tiny spherical "bird's nests" of tangled DNA, about 1 micron  
(millionth of a meter) in diameter, further entangled to one another by 
longer  DNA chains. It behaves something like a mass of rubber bands 
glued together: It  has an inherent shape, but can be stretched and 
deformed. 
Exactly how  this works is "still being investigated,"
 the researchers said, but they  theorize that the elastic forces 
holding the shape are so weak that a  combination of surface tension and
 gravity overcomes them; the gel just sags  into a loose blob. But when 
it is immersed in water, surface tension is nearly  zero -- there's 
water inside and out -- and buoyancy cancels gravity. 
To  
demonstrate the effect, the researchers created hydrogels in molds 
shaped like  the letters D, N and A. Poured out of the molds, the gels 
became amorphous  liquids, but in water they morphed back into the 
letters. As a possible  application, the team created a water-actuated 
switch. They made a short  cylindrical gel infused with metal particles 
placed in an insulated tube between  two electrical contacts. In liquid 
form the gel reaches both ends of the tube  and forms a circuit. When 
water is added. the gel reverts to its shorter form  that will not reach
 both ends.
