zoom Japanese shipping company Nisshin Shipping has been linked to an order for up to seven 82,000 DWT bulkers at China’s Jiangsu Hantong Ship Heavy Industries.The fleet modernization deal, dated last week, comprises five firm orders plus two options, according to the data provided by VesselsValue.The firm Panamax bulkers, valued at USD 24 million a piece, are scheduled for delivery in 2018, while the optional units would be handed over in 2019.Including the latest order, the company has 16 newbuilds on order: five chemical tankers at compatriot Usuki Zosensho, four LR1 tankers at Korea’s Sungdong Shipbuilding and Marine Engineering, and two more bulkers at China’s Jiangsu Hantong and Jiangmen Nanyang, respectively.Out of the above total, six ships are to join Nisshin’s fleet by the end of this year.As World Maritime News reported earlier, the company was busy over the recent period shedding some of its second-hand tonnage, including five Panamax bulkers since December 2016.World Maritime News Staff
A 67-year-old Nepali woman honoured with one of India’s most prestigious awards for freeing thousands of girls from sexual slavery said on Friday it was the unbearable pain of victims that has motivated her to fight trafficking.Anuradha Koirala, founder of the anti-trafficking charity Maiti Nepal, will be presented the Padma Shri – one of the highest civilian awards – by India’s president at a ceremony in March or April, said a government statement this week.”Rescued and rehabilitated 12,000 sex trafficking victims and prevented over 45,000 from being trafficked,” an infographic on Prime Minister Narendra Modi’s website read, listing the names and achievements of some of the 89 Padma award winners.The small, frail teacher-turned-activist said she was encouraged by the award, and it would make her work harder to stop girls being bought and sold in the sex trade.”The pain of victims has motivated me to continue my work,” Koirala told the Thomson Reuters Foundation by phone.”When I see their pain – their mental pain as well as physical pain – it is so troubling that I cannot turn myself away. This gives me strength to fight and root this crime out.”South Asia is one of the fastest-growing region for human trafficking in the world, according to the United Nations Office for Drugs and Crime.Anti-slavery activists say thousands of people mostly from poor villages are trafficked from countries such as Nepal and Bangladesh to India by gangs who sell them into bonded labour or hire them out to unscrupulous employers.Many women and girls are sold into brothels. Others end up as domestic workers or labourers in brick kilns, roadside restaurants or small textile and embroidery workshops.India is home to 40 percent of the world’s 46 million slaves, according to the 2016 Global Slavery Index, produced by the Australia-based Walk Free Foundation.Koirala left her two-decade-long career as a teacher in 1993 and founded Maiti, which means “Mother’s Home” in Nepali, to support victims rescued from sex trafficking who face social stigma and are ostracised by their families and communities.Over the last 24 years, Maiti has established a shelter in Kathmandu, eleven transit homes along the Nepal-India border, three prevention homes where high-risk girls receive counselling and training in skills such as sewing and candle making, two hospitals and a school which teaches around 1,000 children.The organisation also conducts public awareness campaigns on human trafficking, provides legal support to trafficked and victims, and works with police and government officials to rescue victims and apprehend perpetrators.Koirala, affectionately know as “dijju” which means “elder sister” in Nepali, has won numerous awards from across the world for her work, including from the United Nations. In 2010, she was awarded the CNN Heroes Award.”Unless families treat their sons and daughters equally it is very hard to end trafficking and slavery,” she said.The Padma awards recognise achievements from social work and public affairs to medicine and literature. The recipients are announced on Jan. 25, the eve of India’s Republic Day.
A minor girl was allegedly raped by a neighbour at Hugulia village in Daudkandi upazila on Sunday, reports UNB.The alleged rapist was identified as Sheikh Farid, 50, son of late Fazar Ali of Hugulia village.Officer-in-charge of Daudkandi police station Md Rafiqul Islam said Farid picked up the victim from their courtyard and took her to an isolated place where he raped her.Locals rescued the victim after hearing her screams and informed police. She was taken to Comilla Medical College Hospital for medical test, he said, adding that they were trying to arrest the alleged rapist.
Artist’s impression of SS 433. Credit: NASA The only known supercritical accretor in the Milky Way galaxy is SS 433, a highly exotic eclipsing binary star system. Its primary object is likely a black hole. Its secondary companion is believed to be a late A-type star based on its light spectrum. The secondary in SS 433 is losing mass into an accretion disk as it spirals in toward the primary, which is slowly consuming it. In turn, as the accretion disc spirals in toward the primary, it becomes super-heated and emits intense X-rays. Physicists are fascinated by the exotic nature of SS 433, but also by its strong resemblance to ultraluminous X-ray sources (ULXs), which are astronomical sources of X-rays that are less luminous than the nuclei of active galaxies, but are more luminous than any known stellar process. These are sources of X-rays that exceed the Eddington luminosities of neutron stars and stellar black holes. Recently, a group of researchers from Russia and Japan have compared the optical spectra of ULXs to SS 433 and have determined that ULXs with X-ray luminosities of ~1040 erg S-1 must constitute a homogenous class of objects that most likely have SCADs. They have published their results in Nature Physics. The most popular models for ULXs have either intermediate mass black holes with standard accretion disks or stellar-mass black holes with accretion disk luminosity exceeding the Eddington limit. Based on X-ray data alone, it is not possible to distinguish these models, so the researchers have turned to optical spectroscopy to find unique information about ULXs. Using the 8.2 meter Subaru Telescope of the National Astronomical Observatory of Japan, located at the Mauna Kea Observatory on Hawaii, they obtained high-quality spectroscopic data from a number of ULX sources.They have determined that ULX spectra are quite similar to late nitrogen Wolf-Rayet stars (WNLs), which exhibit broad emissions of ionized nitrogen and helium or carbon. They have very high surface temperatures and produce intense stellar winds. The spectra from ULXs also resemble those of luminous blue variable stars (LBVs) in the compact stages of stellar development. Because the physical conditions of its disk wind may be similar to WNL stars, SS 433 also bears a strong resemblance to ULXs. The authors write, “Such spectra of high luminosities with prominent He II emission lines have never been observed from any stellar-mass black hole X-ray binaries, except for SS 433 and those having WNL donors [secondaries losing mass to the accretion disks of primaries in binary systems].” They exclude a number of stellar cases, including ULXs with WNL donors that exhibit stellar winds with the observed spectra. Wind terminal velocity is determined by surface gravity, making it difficult to explain the rapid variability of the He II line width in the recorded spectra. The authors conclude that SS 433 is intrinsically the same as ULXs, but is an extreme case with a particularly high mass accretion rate from its secondary, which accounts for the presence of its persistent jet outflows. © 2015 Phys.org Journal information: Nature Physics Explore further More information: “Supercritical accretion disks in ultraluminous X-ray sources and SS 433.” Nature Physics (2015) DOI: 10.1038/nphys3348AbstractThe black hole mass and accretion rate in ultraluminous X-ray sources (ULXs) in external galaxies, whose X-ray luminosities exceed those of the brightest black holes in our Galaxy by hundreds and thousands of times1, 2, is an unsolved problem. Here we report that all ULXs ever spectroscopically observed have almost the same optical spectra, apparently of WNL type (late nitrogen Wolf–Rayet stars) or LBV (luminous blue variables) in their hot state, which are very scarce stellar objects. We show that the spectra do not originate from WNL/LBV-type donors but from very hot winds from the accretion disks with nearly normal hydrogen content, which have similar physical conditions to the stellar winds from these stars. The optical spectra are similar to that of SS 433, the only known supercritical accretor in our Galaxy3, although the ULX spectra indicate a higher wind temperature. Our results suggest that ULXs with X-ray luminosities of ~1040 erg s−1 must constitute a homogeneous class of objects, which most likely have supercritical accretion disks. Ultra-luminous X-ray sources in starburst galaxies (Phys.org)—Many black holes are believed to have surrounding accretion disks of matter trapped by gravity and spiraling toward the event horizon. Supercritical accretion disks (SCADs) are those with mass accretion rates exceeding the Eddington limit—this describes the maximum possible luminosity of an energetic body when the outward force of radiation is in equilibrium with gravitation. Masses that exceed the Eddington luminosity to produce SCADs emit extremely intense stellar winds from their outer layers.
