ORLANDO, the United States, June 16 (Xinhua) -- U.S. President Barack Obama on Thursday again urged Republican-controlled Congress to pass stricter gun control laws during his visit to Orlando in the wake of the country's deadliest mass shooting incident.


"Those who were killed and injured here were gunned down by a single killer with a powerful assault weapon," Obama told reporters. "The motives of this killer may have been different than the mass killers in Aurora, or Newtown. But the instruments of death were so similar. Now another 49 innocent people are dead. Another 53 are injured. Some are still fighting for their lives."


At least 49 people were killed and 53 others wounded, including a police officer, early Sunday morning in a shooting spree at a popular LGBT nightclub in Orlando, Florida. It was the deadliest terror attack in the U.S. history since 911 in 2001.


The gunman, identified by authorities as Omar Mateen of Port St. Lucie, Florida, was found dead inside the nightclub after a shootout with the police.


"I truly hope that senators rise to the moment and do the right thing. We can stop some tragedies. We can save some lives. If we don't act, we will keep seeing more massacres like this," said Obama.


Following the 2012 school mass shootings in Newtown, Connecticut, which claimed 26 lives, including 20 children, the Obama administration initiated but failed to push stronger gun control laws.


The laws, whose sections included expanded background checks and bans on assault weapons, were stymied in Congress after staunch opposition from Republican lawmakers and gun-rights lobby groups.


During his presidency, Obama presided over more than a dozen of high-profile mass shootings, and in an interview last year he called the failure to reform U.S. gun laws "one of the greatest frustrations" of his presidency.


"If you ask me where has been the one area where I feel that I've been most frustrated and most stymied, it is the fact that the United States of America is the one advanced nation on Earth in which we do not have sufficient common-sense gun safety laws, even in the face of repeated mass killings," Obama told BBC in an interview in July, 2015.

Expertise and Rutherford's ability in constructing and imagining experimental equipment that is fine were critical to another job that would prove to be his most significant contribution. Following his research Rutherford started to examine the effect of radiation on the conductivity from uranium. During this work Mats Zuccarello Womens Jersey , Lord Rutherford discovered that there were two types of radiation, which he called ss rays and a. These could be differentiated by their capacity to penetrate substances: a thin piece of paper would not be passed through by a rays; ss radiation could penetrate thin sheets and was strong.

With the scientist Frederick Soddy, in 1903 Henrik Lundqvist Womens Jersey , Rutherford concluded that atoms caused radiation . The miniature touches were ss rays and the a. This is a ground-breaking thought, since it have been a basic principle of chemistry and physics that atoms were the smallest possible particles and thus indivisible. Rutherford went to show that a -particles were, actually Ryan McDonagh Womens Jersey , a type of the helium atom. Lord Rutherford did this by putting a fine glass bulb including radon gas, which emitted a - particles. The particles would penetrate the bulb's glass but not escape the tube, and could subsequently be assessed.

Within Rutherford Authentic Mika Zibanejad Jersey , these studies and his helper Hans Geiger created an a -particle detector (known now as the Geiger counter) .

In 1909 Rutherford gave his pupil Ernest Marsden the job of analyzing whether metal would deflect the course of an a -particle. Rutherford demonstrated the collision had to happen with something that was little and quite huge (compared to the a -particle) and that carried an electric charge.

Rutherford's work transformed the theory into one of largely empty space from that. Although the experimental results were explained by the new model, it had not been harmonious.

In England the Danish physicist Niels Bohr arrived in 1912 to work with Rutherford, and he used the German physicist Max Planck's quantum theory . According to the theory Authentic Mats Zuccarello Jersey , electrons could just acquire or lose energy in predetermined numbers called quanta. So long as its orbit failed to alter, it'd never fall into the nucleus. Although there have been additional refinements to the Bohr-Rutherford model of the atom electrons don't really orbit--it's a significant model of atomic arrangement. Lord Rutherford won the Nobel Prize in 1908 and was knighted in 1914. He became the Cavendish Professor of Physics. Lord Rutherford was made Lord Rutherford of Nelson. Rutherford died on October 19, 1937 at Cambridge.

Rutherfordium is the very first transactinide element. 259 Rf (half life of about 3.4 seconds). Therefore Authentic Henrik Lundqvist Jersey , should form volatile tetrachlorides that are less volatile and it should act likewise to its analogues titanium and hafnium. The first gas chromatographic studies revealed that rutherfordium forms volatile chlorides a deviation that has been called from relativistic computations.

The first aqueous chemistry studies demonstrated Rf's neutral and anionic complexes to act like the similar complexes rather than showing that Rf is really a transactinide. Comprehensive studies of the extraction chromatography show chemical behaviour much like that found in gas chromatographic experiments of Rf complexes --that's, Rf will not act as expected according .
