The Hellenic Navy (HN) (Greek: Πολεμικό Ναυτικό, Polemikó Naftikó, abbreviated ΠΝ) is the naval force of Greece, part of the Greek Armed Forces. The modern Greek navy has its roots in the naval forces of various Aegean Islands, which fought in the Greek War of Independence. During the periods of monarchy (1833–1924 and 1936–1973) it was known as the Royal Navy (Βασιλικόν Ναυτικόν, Vasilikón Naftikón, abbreviated ΒΝ).The total displacement of all the navy's vessels is approximately 150,000 tons.The motto of the Hellenic Navy is "Μέγα το της Θαλάσσης Κράτος" from Thucydides' account of Pericles' oration on the eve of the Peloponnesian War. This has been roughly translated as "Great is the country that controls the sea". The Hellenic Navy's emblem consists of an anchor in front of a crossed Christian cross and trident, with the cross symbolizing Greek Orthodoxy, and the trident symbolizing Poseidon, the god of the sea in Greek mythology. Pericles' words are written across the top of the emblem. "The navy, as it represents a necessary weapon for Greece, should only be created for war and aim to victory."...............The Hellenic Merchant Marine refers to the Merchant Marine of Greece, engaged in commerce and transportation of goods and services universally. It consists of the merchant vessels owned by Greek civilians, flying either the Greek flag or a flag of convenience. Greece is a maritime nation by tradition, as shipping is arguably the oldest form of occupation of the Greeks and a key element of Greek economic activity since the ancient times. Nowadays, Greece has the largest merchant fleet in the world, which is the second largest contributor to the national economy after tourism and forms the backbone of world shipping. The Greek fleet flies a variety of flags, however some Greek shipowners gradually return to Greece following the changes to the legislative framework governing their operations and the improvement of infrastructure.Blogger Tips and Tricks

The ....."epidemic" of earthquakes..goes on...[ 925 ]

7.1 quake in China kills 400

The quake strikes a remote area of Qinghai province in western China that is mostly populated by Tibetans. About 8,000 are injured.

An earthquake that Chinese officials measured at magnitude 7.1 rocked a remote, mostly Tibetan-populated county in western China early Wednesday, killing at least 400 people and injuring at least 8,000, according to state television reports.

The quake struck in Qinghai province about 20 miles from the county seat of Yushu, where it toppled houses, an elementary school and part of a Buddhist tower in a public park and seriously damaged the main hospital in town, officials told Chinese media.

"In a flash, the houses went down. It was a terrible earthquake," one witness said.

Yushu is about 500 miles southwest of Qinghai's capital, Xining, and has a mostly Tibetan population of 100,000 people, many of them herdsmen in the mountainous, rural area.

Numerous houses made of mud and logs in the traditional manner collapsed during the quake and its aftershocks.

"The death toll may rise further as lots of houses collapsed," army commander Wu Yong told the state-run China Daily. "Roads leading to the airport have been damaged, hampering the rescue effort."

In Jiegu, a township near the epicenter, more than 85% of the houses had collapsed, said Zhuo Huaxia, a local Tibetan official.

"Many are buried in the collapsed houses," he told the official New China News Agency. "There are still lots of others who are injured and being treated at local hospitals."

With phone lines down, rescuers also were hindered by telecommunications problems slowing attempts at coordination. State TV showed footage of paramilitary police using shovels to dig around a house with a collapsed wooden roof. A local military official, Shi Huajie, told state broadcaster CCTV that rescuers were working with limited equipment.

"We don't have any excavators. Many of the people have been buried, and our soldiers are trying to pull them out," Shi said. "It is very difficult to save people with our bare hands."

Five thousand tents and 100,000 thick, cotton coats and blankets were being sent to help survivors cope with strong winds and temperatures of about 43 degrees Fahrenheit, the Qinghai provincial government said.

The U.S. Geological Survey said the quake measured a magnitude 6.9.

There were at least six aftershocks, the strongest a magnitude 6.2.

In 2008, a magnitude 7.9 earthquake in neighboring Sichuan province left almost 90,000 people dead or missing.

City’s Worst Fire in Years[ 923 ]

Before City’s Worst Fire in Years, History of Neglect

Hamilton Boardman/The New York Times

A fire that broke out in Chinatown on Sunday night injured 33 people and left 200 homeless.

The building in Chinatown where an enormous blaze started late Sunday night had more than two dozen open violations for hazardous conditions, including missing smoke detectors, lead paint and other problems that signified a history of neglect, city records show.

An 87-year-old man’s body was found Monday night. The fire took about 250 firefighters to extinguish.

The New York Times

Tenants had complained through the winter that they had no heat and that the building was riddled with mold and exposed wiring. At the same time, the owners had put the building on the market for the third time in five years with no apparent success.

Late Monday night, firefighters recovered the body of a missing 87-year-old man from the top floor of one of the three buildings where the fire had spread. Earlier, they had been unable to get into the building to search because of the danger of a collapse, but at 8:20 p.m., they found the body of a man identified by his relatives as Sing Ho.

At its peak, the fire was visible from across the East River. Hundreds of tenants were evacuated; it was a seven-alarm blaze, drawing some 250 firefighters to battle it. Fire officials said it was the largest blaze in the city in more than two years.

By the time the fire was under control, about 2:15 a.m. on Monday, some 200 people had been left homeless and dozens had been injured.

Two elderly men who lived in one of the buildings, on Grand Street, were treated for smoke inhalation and listed in serious to critical condition at Beth Israel Medical Center on Monday, said Firefighter James Long, a department spokesman. A Beth Israel spokeswoman said Monday night that the hospital had treated about a dozen people, and that all of them had been released except for one, who was in stable condition.

Investigators were trying to determine what started the fire, in which 33 other people were hurt, including 29 firefighters who suffered minor injuries. Officials said there was no reason to believe the fire was arson, but as of Monday evening, fire marshals had not been able to go into the rubble to search for clues.

Julie Chen, 26, who lived on the fourth floor of the building at 283 Grand Street, where the fire started, said, “I have everything up there.” Staring up at the smoldering hulk on Monday, she added: “I’m lucky I have a pair of shoes right now. I don’t know where to go.” Firefighters did not learn that the 87-year-old was missing until two women showed up at Councilwoman Margaret Chin’s district office about 3 p.m. seeking news about their father’s whereabouts.

“They went through every single hospital looking for him,” Ms. Chin said hours before the body was found. Mr. Ho lived on the top floor of 285 Grand Street with one of his daughters, who was at work when the fire broke out, Ms. Chin said.

In the chaos of the blaze, it took some time for the daughters to realize he was missing, Ms. Chin said. She added that the family had presumed he was dead.

Firefighter Long said the blaze broke out in the back of a store on the ground level of 283 Grand Street, a century-old, six-story building fronted by fire escapes. Pillars of flame shot over the rooftops as the fire quickly spread. By midnight, it had reached seven alarms, the first to do so since the Deutsche Bank building fire in August 2007, which sent plumes of smoke over ground zero and left two firefighters dead.

Ms. Chin, whose district includes the buildings, said 283 Grand Street and 285-287 Grand next door, suffered the brunt of the damage and would have to be demolished. The buildings are owned by Fair Only Realty, whose chief officers are listed variously in city records as Ralph Sherman and Solomon Scheinfeld, both at the same address in Flushing, Queens. They did not return phone calls seeking comment.

The owners put the buildings, which were home to two ground-level stores and 30 apartments, on sale for the third time in five years in December, asking $13.5 million, according to Central City Brokerage, which carried the listing. Before the fire, the asking price had been dropped to $9.25 million. Of the 30 apartments, five were rent-controlled, 23 were rent-stabilized and two were rented at market rate, according to the listing.

“Two of the buildings are in really bad shape,” Ms. Chin said. “There’s no roof; it’s really just a shell, so they’re going to have to tear them down.”

Also damaged in the fire were 281 and 289 Grand Street, fire officials said.

Ms. Chen, who paid $770 a month for a one-bedroom apartment on the fourth floor, said residents had become frustrated with the landlord. “In the winter time, in the coldest days,” she said, “we would have no heat, no hot water.”

Trash also piled up in the basement, she said.

After a number of complaints to 311, the heat would be restored for a few days, then vanish again, she said.

“Excuse after excuse,” she said. “Very frustrating.”

Chris Kui, executive director of Asian Americans for Equality, a neighborhood advocacy group, said his organization had heard complaints about the building where the fire started. “We knew it had a lot of issues,” he said.

On Monday, the group was trying to find shelter for the people who had lost their homes, many of whom were elderly, Mr. Kui said.

Chen Hui, who lived on the third floor of 283 Grand Street, was talking with his wife in China on a Web cam when he realized that he and his parents, who also lived there, had to get out.

“I heard my mother yelling, ‘It’s fire! It’s fire!’ ” he said on Monday. Standing across the street from the building, he said, “Everything I own is gone.”

Φυσικά μνημεία στο βυθό της Καραϊβικής.. [ 922 ]


Απόκοσμα υδροθερμικά φρεάτια βιντεοσκοπήθηκαν στο βυθό της Καραϊβικής

Το νερό που αναβλύζει από τη στήλη φτάνει τη θερμοκρασία τήξης του μολύβδου (Πηγή: NOC)
Λονδίνο ( In.gr, News 13/4/200)

Βρετανική ερευνητική αποστολή ανακάλυψε τα βαθύτερα υδροθερμικά φρεάτια που έχουν εντοπιστεί μέχρι σήμερα, στήλες σε ύψος διώροφου κτιρίου που εκτινάσσουν υπέρθερμο νερό σχεδόν πέντε χιλιόμετρα κάτω από την επιφάνεια της θάλασσας στην Καραϊβική.

Τα υδροθερμικά φρεάτια -πηγές στον βυθό από τις οποίες αναβλύζει καυτό, συνήθως κατάμαυρο νερό- είχαν ανακαλυφθεί στον Ειρηνικό πριν από τρεις δεκαετίες και συνήθως βρίσκονται σε ηφαιστειακά ενεργές περιοχές, σε βάθος ενάμισι έως τριών χιλιομέτρων.

Γύρω από τα φρεάτια αυτά έχουν ανακαλυφθεί ολόκληρα οικοσυστήματα που αντλούν ενέργεια αποκλειστικά από τις χημικές ουσίες που περιέχει το καυτό νερό και εξελίσσονται εντελώς αποκομμένα από τα υπόλοιπα οικοσυστήματα του πλανήτη. Πολλοί βιολόγοι πιστεύουν μάλιστα ότι τα υδροθερμικά φρεάτια προσφέρουν στοιχεία για την εμφάνιση της ζωής στην αρχέγονη Γη και πιθανώς και σε άλλους πλανήτες.

Τα φρεάτια που ανακαλύφθηκαν από τη βρετανική αποστολή στη λεγόμενη Τάφρο του Κέιμαν της Καραϊβικής, σε βάθος 5 χλμ, είναι τα βαθύτερα που γνωρίζει μέχρι σήμερα η επιστήμη.

«Ήταν σαν να περιπλανιέμαι στην επιφάνεια ενός άλλου κόσμου» δήλωσε εντυπωσιασμένος ο γεωλόγος Μπράμπλεϊ Μέρτον, χειριστής του ρομποτικού βαθυσκάφους Autosub6000, με το οποίο εντοπίστηκαν, φωτογραφήθηκαν και βιντεοσκοπήθηκαν οι μοναδικές γεωλογικές δομές.

Με την πάροδο των αιώνων, τα διαλυμένα συστατικά που μεταφέρει το νερό -όπως σίδηρος και χαλκός- καθώς αναβλύζει από το υπόστρωμα έχουν σχηματίσει πανύψυλες στήλες σαν φυσικές καμινάδες.

«Οι ιριδίζουσες αποχρώσεις των ορυκτών στηλών και το φθορίζον μπλε του μικροβιακού στρώματος που της καλύπτει δεν έμοιαζε με τίποτα που είχα δει στο παρελθόν» σχολίασε ο Μέρτον.

Λόγω της μεγάλης πίεσης σε αυτό το βάθος, το νερό που πηγάζει από τα φρεάτια παραμένει σε υγρή κατάσταση παρόλο που φτάνει τη θερμοκρασία τήξης του μολύβδου.

Η αποστολή του βρετανικού Εθνικού Κέντρου Ωκεανογραφίας, σε συνεργασία με Αμερικανούς και Νορβηγούς ερευνητές, θα παραμείνει στην περιοχή μέχρι τις 20 Απριλίου προκειμένου να συνεχίσει τις χημικές και βιολογικές αναλύσεις, ενώ αργότερα θα ακολουθήσει και νέα αποστολή στην Τάφρο του Κέιμαν.
