Vietnamese boy, 10, dead after falling into 115-foot concrete hole

Vietnamese authorities announced Wednesday that the 10-year-old boy trapped down a 115-foot deep concrete hole since New Year’s Eve is dead, according to reports. 

The boy, identified as Thai Ly Hao Nam, initially was heard crying for help when he slipped through a 10-inch diameter shaft at a bridge construction site in the Dong Thap province Saturday morning while searching for scrap metal with friends. 

Despite oxygen being pumped down into the hole amid efforts to reach him, the boy stopped interacting with rescuers Monday. Crews lowered down a camera to try to pinpoint his location. 

The BBC reported Wednesday the boy was cut while rescuers were trying to raise the pillar.

Doan Tan Buu, deputy chief of the southern Vietnam province, also said not enough oxygen could reach the 10-year-old, who had already suffered multiple injuries. 

“We had prioritized the rescue of the boy. However, the conditions mean it is impossible the boy has survived,” he said.

The official said he consulted with medical experts before declaring the boy’s death Wednesday, but crews would still work to recover the 10-year-old’s body as soon as possible for proper burial, AFP reported. The official added that doing so would be a “very difficult task.” 

Vietnamese Prime Minister Pham Minh Chinh on Monday tapped federal rescuers to join local authorities’ efforts to save the boy, AFP reported.

Hundreds of soldiers and engineering experts were mobilized Tuesday to try to save him, according to the BBC. Crews tried drilling to soften the soil surrounding the pillar to attempt to bring the pillar upward out of the ground. They also lowered down a 62-foot pipe to try to remove mud and water to soften pressure around the pillar.

Vietnam rescuers race to save boy trapped down 115-foot concrete hole since New Year’s Eve

Hundreds of rescuers in Vietnam were battling for a third day Monday to save a 10-year-old boy who fell more than 100 feet down a shaft at a construction site on New Year’s Eve.

The boy was reportedly heard calling for help shortly after he fell into the shaft of a hollow concrete pile just 25 cm (10 inches) in diameter at a bridge construction site in the Dong Thap province Saturday morning while searching for scrap metal with friends. 

But as of Monday, he hasn’t been responding to rescuers, who lowered a camera to help locate the boy’s position down the estimated 115-foot-long support pillar, according to Reuters.

Efforts to lift the pile with cranes and other heavy equipment have so far been unsuccessful.

Body encased in concrete removed from basement of Philadelphia home

Police removed a body encased in concrete from the basement of a Philadelphia home after receiving a tip that a woman who has been missing for eight years was buried there.

The row home on Burton Street in the Wissinoming section of the city has been a focus of a police investigation since they received the tip last week, WPVI reported.

Inside the home, investigators found a hoarding situation and spent two days removing trash and other debris. By Thursday evening, police had found evidence of human remains, law enforcement sources confirmed to the news outlet.

On Monday officials were finally able to reach the remains, which were buried beneath a foot of concrete, and carefully chisel out the woman’s body.

Examiners enter the Philadelphia home, which investigators cleared out for two days before finding evidence of human remains.

The medical examiner will conduct an autopsy to determine whether the deceased individual — who has not yet been identified — was killed or died of natural causes before they were buried in the concrete.

Baffled neighbors told WPVI that the family who lived in the home have been gone for days.

“You don’t know what’s going on — all these rumors, all these stories,” said neighbor Melissa Rosario. “It took them so long to clean out the house. It’s like, ‘Oh maybe it’s a lie and maybe there’s not a body there.’ And then to hear the body was there for eight years?”

Police received a tip last week that a missing woman’s body was buried in the home.

Other neighbors told WCAU that they’ve seen investigators and workers in hazmat suits haul multiple dumpsters of trash out of the home in the six days since they executed a search warrant.

Police have not indicated how much longer they plan to be at the house.

Turkey demands Sweden take concrete steps prior to NATO approval | Russia-Ukraine war News

Ankara is demanding that Sweden and Finland extradite Kurdish rebels before lifting a veto on their membership bid.

Ankara has conveyed its request for Sweden to work towards countering “terrorism” threats before clearing the country’s application to join NATO, Turkish President Recep Tayyip Erdogan has said.

“We understand their security concerns, and we want Sweden to respond to ours,” Erdogan said after meeting Sweden’s prime minister at the presidential palace in Ankara on Tuesday.

The Turkish leader, who has accused the Scandinavian nation and its neighbour Finland of harbouring Kurdish rebel groups that are outlawed in Turkey, added that he “sincerely wished” that Sweden joined the US-led military alliance.

Another meeting on the NATO membership bid was scheduled for later this month, he said, without specifying the date.

Sweden and Finland abandoned their longstanding policies of military nonalignment and applied for NATO membership this year after Russian forces invaded Ukraine in February, fearing that Russian President Vladimir Putin might target them next.

But Turkey, which joined NATO in 1952, has not yet endorsed their accession, which requires unanimous approval from existing alliance members.

Sweden’s Prime Minister Ulf Kristersson said he understood Turkey’s fight against “terrorism” and promised to respond to its requests.

Erdogan has demanded that Oslo and Helsinki extradite members of the Kurdistan Workers’ Party (PKK), which has battled against the Turkish state for decades and is considered a terrorist group by Ankara and its Western allies.

Turkey accused Sweden, in particular, of leniency towards the PKK and its Syrian offshoot, the People’s Protection Units (YPG). In June, it said it had provided Oslo and Helsinki with a list of people it wanted extradited.

The PKK is blacklisted by Ankara and most of its Western allies. But the YPG has been a key player in the US-led military alliance combatting the ISIL (ISIS) group in Syria.

Kristersson described Tuesday’s meeting with Erdogan as “very productive”.

“Sweden will live up to all the obligations made to Turkey in countering the terrorist threat,” he said.

“My government was elected just a few weeks ago on a mandate to put law and order first. And this includes countering terrorism and terrorist organizations like the PKK in Sweden,” he added.

While Sweden has in the past voiced support for the YPG and its political wing, Kristersson’s government appears to be distancing itself.

The Swedish parliament said it would vote next week on a constitutional amendment that would make it possible to strengthen “anti-terror” laws, a key demand from Turkey.

The amendment would enable new laws to “limit freedom of association of groups involved in terrorism”, the parliament said in a statement, adding that the vote was scheduled for November 16.

NATO Secretary General Jens Stoltenberg visited Ankara last week to press the case for Sweden and Finland, saying their accession would “send a clear message to Russia”.

Stoltenberg stressed the two had agreed on concessions to Turkey in June, which included addressing its request for “terror suspects” to be deported or extradited.

Finnish President Sauli Niinisto told journalists on Monday he expected joining NATO would “happen in reasonable time”.

In August, Sweden announced it had decided to extradite to Turkey a man in his 30s who was wanted for fraud. The move was the first case since Turkey demanded collaboration on extraditions from Stockholm.

Turkey lifted its veto over Finland and Sweden’s bid in June after weeks of tense negotiations. Turkey has since expressed frustration over the lack of progress.

EXCLUSIVE In letter, Sweden lists ‘concrete actions’ on Turkey’s concerns over NATO bid

  • Sweden said it had stepped up efforts against Kurdish militants
  • Says it will address pending extradition requests
  • Letter meant to demonstrate Sweden’s commitment to pledges
  • Sweden asked to join NATO after Russia’s invasion of Ukraine
  • Turkey initially vetoed, accused Sweden of harbouring militants

ISTANBUL, Oct 21 (Reuters) – Sweden has taken “concrete action” to address Turkey’s concerns over its NATO membership bid, including stepping up counter-terrorism efforts against Kurdish militants, Stockholm told Ankara in a letter dated Oct. 6 and seen by Reuters.

The two-page letter gives 14 examples of steps taken by Sweden to show it “is fully committed to the implementation” of a memorandum it signed with Turkey and Finland in June, which resulted in NATO member Turkey lifting its veto of their applications to the trans-Atlantic security alliance.

Sweden and Finland launched their bids to join NATO in May in response to Russia’s invasion of Ukraine, but ran into objections from Turkey, which accuses the two Nordic countries of harbouring what it says are militants from the banned Kurdistan Workers Party (PKK) and other groups.

Stockholm and Helsinki deny harbouring terrorists but have pledged to cooperate with Ankara to fully address its security concerns, and to lift arms embargoes. Yet Turkey’s President Tayyip Erdogan said as recently as Oct. 6 that its demands had not yet been met.

In its letter to Turkey, Sweden said that “concrete action has been taken on all core elements of the trilateral agreement”.

Sweden’s security and counter-terrorism police, Sapo, “has intensified its work against the PKK”, and it made “a high-level visit” to Turkey in September for meetings with Turkey’s MIT intelligence agency, the letter said.

Sweden’s foreign ministry and the communications arm of Erdogan’s office each did not immediately respond to a request for comment on the letter.

Swedish officials delivered the letter, which was not previously reported, to Erdogan’s office and the foreign ministry at the weekend, a source familiar with the situation said, requesting anonymity due to sensitivity over it.

The letter was meant to reassure Turkey of Sweden’s efforts amid ongoing bilateral talks and to encourage ultimate approval of the NATO membership bid, the source added.

According to the letter, Swedish authorities “carried out new analyses of PKK’s role in threats to Sweden’s national security and in organised crime (and) this is likely to lead to concrete results.”

The PKK, which took up arms against the Turkish state in 1984, is considered a terrorist group by Turkey, the European Union and the United States. As part of talks over the June memorandum, Turkey has sought the extradition of 73 people from Sweden and a dozen others from Finland, where it is concerned with other groups.

The letter says Stockholm extradited one Turkish citizen on Aug. 31 upon Ankara’s request, after an Aug. 11 decision, and that a total of four extraditions have been made to Turkey since 2019.

Extraditions were discussed by a Swedish delegation visiting Ankara in early October, according to the letter.

“Sweden is committed to address…pending extradition requests of terror suspects expeditiously and thoroughly,” taking into account Turkish intelligence and in accordance with Swedish law and the European Convention on Extradition, the letter said.

Turkey will continue consultations with Sweden and Finland “to pursue full implementation of the memorandum,” Turkish diplomatic sources told Reuters. However steps “need to be taken…(in) combatting terrorism, prevention and punishment of incitement to terrorism, improvement of security and judicial cooperation,” the sources added.

The parliaments of all 30 North Atlantic Treaty Organization (NATO) member states’ must approve Sweden and Finland’s bids, which would mark a historic enlargement of the alliance as the war in Ukraine continues.

In a sign that talks were progressing, Sweden’s foreign minister said on Friday he expects the last two holdouts, Turkey and Hungary, to vote soon on its NATO applications.

Erdogan was quoted by Turkish broadcasters as saying on Friday that Sweden’s newly appointed Prime Minister Ulf Kristersson backs the fight against terrorism and that they would meet to discuss the NATO bid and extraditions.

A day earlier Kristersson said after meeting with NATO’s secretary general that his government “will redouble efforts to implement the trilateral memorandum with Finland and Turkey”.

Sound From NASA’s Saturn V Rocket Did Not Melt Concrete

On November 9, 1967, a 363-foot-tall (111-meter) Saturn V rocket launched from NASA’s Kennedy Space Center, generating 7.5 million pounds of thrust. The blast created by the Apollo 4 liftoff was among the loudest noises ever produced by our species, scientists calculated at the time. In fact, the roar was so loud that it sparked a rumor that the Saturn V launch melted concrete and lit grass on fire over a mile away.

A team of scientists is now claiming to have put this rumor to rest, suggesting that, while the Saturn V rocket launch was very, very loud, it was not loud enough to melt concrete. As NASA prepares to send the even-more powerful Space Launch System (SLS) on the Artemis 1 mission to the Moon and back, the agency will use water in an attempt to partially dampen the rocket’s blast, which is predicted to be even louder than Saturn V.

When the Saturn V launched, not a lot of data was available to precisely calculate the amount of noise. To estimate the acoustic levels of a Saturn V launch, the scientists behind the recent study created a physics-based model that churned out a value of 203 decibels. “Decibels are logarithmic, so every 10 decibels is an order of magnitude increase,” Kent Gee, a researcher at Brigham Young University and lead author of the study published in The Journal of the Acoustical Society of America, said in a statement. “One hundred and seventy decibels would be equivalent to 10 aircraft engines. Two hundred would be 10,000 engines!” As an aside, the human threshold for pain starts at around 130 decibels.

So it’s no wonder the launch inspired the highly exaggerated myth, but the study confirms that the noise generated by Saturn V’s liftoff is not enough to burn distant grass, let alone melt concrete. The study claims that the myth likely started due to confusion between sound power and sound pressure, with one being akin to wattage coming from a light bulb and the second being like the brightness emitted from that same light bulb, according to the researchers. Therefore, it’s likely that prior attempts to calculate the acoustic power of the Saturn V launch were incorrect, leading to the misconception. “The Saturn V has taken on this sort of legendary, apocryphal status,” said Gee.

At the time, Saturn V was the most powerful rocket built by NASA and it was used to launch Apollo missions to the Moon. But now it’s time for NASA’s SLS rocket, which is currently sitting atop launchpad 39B (Saturn V took off from 39A) ahead of the Artemis 1 launch scheduled for August 29. This time, however, NASA is prepared for all the ruckus generated by the launch of a megarocket. The space agency has developed a sound suppression system that will release 450,000 gallons (2 million liters) of water onto the mobile launcher platform immediately before the rocket fires its main engine. The water will flow to special outlets on the platform by way of gravity, reducing the acoustic levels to about 142 decibels.

The researchers behind the new study plan to use the same framework used in the Saturn V analysis to predict the sounds coming from SLS, and also measure the acoustic levels during the actual launch to help refine their predictions in the future.

Saturn V Rocket Was LOUD – As Loud as 10,000 Jet Engines – but Didn’t Melt Concrete

Physics-based acoustical models and historical data combine to correct common misconceptions about the most powerful rocket launched to date.

The

Such ideas have been proven false. Researchers from Brigham Young University (BYU) used a physics-based model to estimate the acoustic levels of the Saturn V rocket. They obtained a value of 203 decibels, which matches the very limited data recorded in the 1960s. The study appears in The Journal of the Acoustical Society of America, published on behalf of the Acoustical Society of America by AIP Publishing.

To put that number into perspective, commercial jet engines range from around 120 to 160 decibels.

“Decibels are logarithmic, so every 10 decibels is an order of magnitude increase,” said author Kent L. Gee, of BYU. “One hundred and seventy decibels would be equivalent to 10 aircraft engines. Two hundred would be 10,000 engines!”

While the Saturn V was indeed extremely loud, that kind of power is nowhere near sufficient to melt concrete or start grass fires. If reports about these phenomena are true, they likely stem from radiative heating via the plume or debris.

Some of the misunderstanding originates from confusing sound power with sound pressure. The former is like the wattage from a light bulb. The latter is like the brightness from the same bulb: It depends on how far away you’re standing. Mistakes in calculations, changes to the decibel reference system, and the propagation of misinformation have also led to compounding errors.

“The Saturn V has taken on this sort of legendary, apocryphal status,” said Gee. “We felt that, as part of the JASA special issue on Education in Acoustics, it was an opportunity to correct misinformation about this vehicle.”

No, NASA’s massive Saturn V rocket didn’t melt concrete with sound

There are more than a few popular myths that have permeated the annals of space history, including one that the launch of th Saturn V rocket was so loud that the sound itself melted concrete and set fire to grass more than a mile away. Sadly, as many myths go, that’s simply not true.

Researchers at Brigham Young University (BYU) in Utah have created a physics-based model of a Saturn V rocket launch to estimate its acoustic levels, determining that it had a value of 203 decibels. That nearly matches NASA’s own recording of 204 decibels, based on a test of the Saturn V’s first stage run at NASA’s Stennis Space Center in Mississippi. 

For context, sounds above 200 decibels are extremely loud — an ambulance siren hits 120 decibels, while jet engines average about 140 decibels at takeoff, according to the National Institute of Occupational Safety and Health. “Decibels are logarithmic, so every 10 decibels is an order of magnitude increase,” BYU professor Kent L. Gee, lead author of a paper on the team’s research, said in a statement. “One hundred and seventy decibels would be equivalent to 10 aircraft engines. Two hundred would be 10,000 engines!”

While 200-plus decibels is certainly loud enough to rupture an eardrum (Saturn V launch viewers were kept 3.5 miles (4 kilometers) away from the pad for safety), it’s not loud enough to melt concrete or start grass fires more than a mile away. The team suspects that those effects, if they happened at all, would have been caused by radiative heat from the plume or debris, not sound.

“The Saturn V has taken on this sort of legendary, apocryphal status,” Gee said. “It was an opportunity to correct misinformation about this vehicle,” he noted of the research.

While the new Space Launch System (SLS) rocket will be larger and louder than the Saturn V, NASA has since implemented a sound suppression system into its launch pads. For SLS, 450,000 gallons (2 million liters) of water will rush onto the pad during launch, reducing the rocket’s acoustical levels. The system will not only protect viewers’ ears, but also the rocket’s payloads.

The team’s research was published Tuesday (Aug. 23) in the Journal of the Acoustical Society of America.
