Maersk Honam Fire Underscores Importance of Cargo Insurance

first_imgzoom The Maersk Honam fire from earlier this month serves as a reminder of the importance of cargo insurance, says online freight forwarder iContainers.“Given that Maersk has now declared general average, which means that the surviving cargo has to pay a share of the cost for the vessel damage, the tow, clean up, legal settlements, etc,” Klaus Lysdal, Vice President of Sales and Operations at iContainers, said.By law, all shipping carriers are obliged to offer a minimum amount of insurance, but it offers limited coverage. Hence, shippers need to invest in additional coverage to protect themselves from worst-case scenarios, the freight forwarder noted.Based on the latest update, Maersk Line’s ultra large containership will be towed to Jebel Ali, the UAE, where its cargo will be off-loaded.However, the estimated time of arrival (ETA) is still to be confirmed and may be approximately two weeks from now, Mediterranean Shipping Company (MSC) said citing its 2M alliance partner.Most containers located in front of the accommodation area are feared to be damaged by fire, heat or the water used to fight the fire.Furthermore, before the fire-stricken vessel is allowed to berth, port authorities will want to make sure that all fire on board have been extinguished and determine the condition of the Honam, which is a process that could still drag on, iContainers added.“For clients who have insurance, filing the claim with their insurance will help speed up the process of releasing their cargo,” explains Lysdal.“Plus, claims are generally processed quicker through insurance companies. Without insurance, you may be stuck with the carrier’s liability which is listed on the back of the Bill of Lading: USD 500 per unit.”Since Maersk Line has declared general average, shippers who did not purchase a general average coverage insurance will be liable to pay a proportional portion of the damage.“Without cargo insurance, your cargo is likely to be held hostage for payment of those charges. Simply said, without insurance, you stand to gain nothing or next to nothing at most,” Lysdal added.last_img read more

Messi banned for three months after CONMEBOL corruption outburst

first_imgAsuncion: Argentina star Lionel Messi was banned from playing for his national team for three months and fined 50,000 on Friday by CONMEBOL after he heavily criticized the South American football governing body during the Copa America. The 32-year-old Barcelona forward had accused CONMEBOL of “corruption” after he was sent off against Chile during the third-place play-off during the tournament in Brazil, which ended last month. Messi was angered by two incidents during the June-July Copa hosted by bitter rivals Brazil. Also Read – Puducherry on top after 8-wkt win over Chandigarh Argentina were denied two penalty claims in their 2-0 semi-final defeat to the hosts, after which Messi claimed Brazil were “managing a lot in CONMEBOL these days.” And when he was harshly dismissed in the next game, which Argentina went on to win 2-1, he couldn’t contain his anger. “Corruption and the referees are preventing people from enjoying the football and they’re ruining it a bit,” Messi said. He was given his marching orders after a first-half scuffle with Chile captain Gary Medel in which television pictures suggested he’d done little wrong. Also Read – Vijender’s next fight on Nov 22, opponent to be announced later The CONMEBOL statement on its website didn’t specify why Messi was being punished but said it was related to articles 7.1 and 7.2 of its disciplinary regulations. One such clause refers to “offensive, insulting behavior or making defamatory protests of any kind.” Another clause mentions “breaching the decisions, directives or orders of the judicial bodies.” The ban means only that Messi will miss a handful of friendly matches as Argentina’s next competitive fixture is not until the South American qualifiers for the 2022 World Cup in Qatar begin in March. However, he has already received a one-game ban from CONMEBOL for his red card against Chile meaning he’ll miss the first of those. Argentina have two friendlies lined up in the United States in September against Chile and Mexico and another in October away to Germany. Messi would miss all three of those but be free to play for his country again in November.last_img read more

The plight of neglected animals at Casablancas Ain Sbaa Zoo

first_imgBy Zineb El Bekkari- Casablanca That humans suffer the worst deplorable situations imaginable on a daily basis is something that we might have grown accustomed to in Morocco. To see voiceless animals caged for life, deprived of food, and resigned to their plight, is heartbreaking and calls for alarm. The Zoo of Ain Sebaa, located in Casablanca, the fledgling economic hub of Morocco, was an institution that was once the pride jewel of every Moroccan. The sad reality is that the Zoo has fallen on a downward hard times due to neglect and mismanagement for years, and has become more of a moral pitiful slow death of the animals living there under some of the most unsanitary despicable conditions those animals are subjected to everyday. The zoo was a curious attraction to countless people from different ages and different parts of Morocco for decades. Now it is but a dilapidated long forgotten facility forsaken by time and misery and the misfortune of the resilient animals housed there. The animals continue to make do with the meager rations they receive every now and then from the keepers. Lodged in cages with leaky roofs and clogged drains, many of these animals have surrendered to the benevolence of caring banana throwers here and there, pieces of meat here and there, and regular meals come most irregularly to them. No one knows for sure how this fall from grace came about to afflict Ain Sbaa zoo, but we know for sure that it needs some urgent attention before animals start dying from preventable diseases and malnutrition. Memories of kids begging their parents for weeks to get them to the zoo on the weekend were now just memories that haunt the conscience of those who still care. The sounds of their laughter as they were first introduced to a real monkey still resonate in my ears and in my hollow heart. Visits to the Zoo taught kids to appreciate other forms of life and instill basic values such as respect for all creatures large and small. Respect for the animals that were not native to Morocco and were brought in as guests. They end up living in such unhospitable cages day in and day out.The Zoo today is nothing but a stinky repulsive home to the very animals that were uprooted from their natural habitat only to end up bleeding life because they were uncared for, neglected, and deprived of the most basic needs. Perhaps the first feeling that hits you once you set foot on its ground is that of despair for the animals.During the last visits that we made to the Zoo, we couldn’t see one single guard in charge of making rounds to monitor the tours. Previously, three thieves climbed the walls of the Zoo in their attempt to steal the Zoo’s only ostrich. Had there been a guard in there, the AMPAE believed, it wouldn’t have been possible for these men to have injured the largest living bird. On the bright side, the redevelopment of the zoo will be launched soon, but the fate of those animals is anyone’s guess. How are Moroccans going to be assured that the animals are not in danger? There is a general consensus among all who see the conditions of the animals at the zoo that something needs to be done urgently to prevent animal starvation and mistreatment at others zoos in the country.A 3rd visit to the zoo will take place this Sunday, at 10am Ain Sebaa Zoo to raise awareness about this crisis, and to give the starving animals food and water. More pictures of the zoo can be seen at the Association Marocaine pour la Protection des Animaux et de l’Environment on Facebooklast_img read more

UN notches up swine flu pandemic alert to level 5

29 April 2009Seeing the swine flu virus spread within a raft of countries, the United Nations health agency today raised the international alert to Phase 5 on a six-point scale, signalling an imminent pandemic and urging all countries to intensify preparations. “This change to a higher alert is a signal to Governments, to ministries of health and other ministries, to the pharmaceutical and the business communities, that certain actions now should be undertaken with extreme urgency,” Margaret Chan, Director-General of the World Health Organization (WHO) said in announcing the move during a teleconference with the world press.“All countries should immediately now activate their pandemic surveillance plans,” she said, calling on all to remain on high alert for clusters of influenza-like illness and pneumonia. Early detection and treatment of cases, and infection controls in all health facilities were also critical, she said.Alert Phase 5 meant that sustained human to human transmission had been confirmed, with widespread community outbreaks, in at least two countries in one WHO region, she said. International cooperation was particularly important she maintained, warning that the H1N1 influenza virus has shown its “capacity to spread rapidly to every country in the world.” She added that she had reached out to donor countries and international organizations to mobilize resources, particularly for developing countries which are usually more vulnerable to the deadliest effects of pandemics.Fortunately, she said the world is better prepared for an influenza pandemic than any time in history, due to the substantial investments made to prepare for the H5N1 virus, or avian flu. “For the first time in history, we can track the evolution of a pandemic in real time,” she said.She thanked countries, particularly the United States, Canada and Mexico, for their strong cooperation with WHO since the outbreak became evident. “New diseases, by definition, are poorly understood, and WHO and health authorities will not have all the answers immediately,” she acknowledged, while vowing, “But we will get them.”The agency, she pledged, would continue tracking the virus at the epidemiological, clinical and biological levels, and make their information public as soon as it is analyzed. In an earlier teleconference today, WHO Assistant Director-General Keiji Fukuda said that there has been an increase in lab-confirmed cases – from 79 yesterday to 114 – been reported in Canada, the US, Mexico, Israel, Spain, the United Kingdom and New Zealand.“It’s clear that the virus is spreading, and we don’t see any evidence of it slowing down at this point,” Mr. Fukuda saidHe said that while preliminary results showed that the virus did originate in pigs, he stressed that there is no evidence that people are now getting sick from pigs or pork products. He emphasized that experts are continuing to study the situation and that there are still unanswered questions – for example, it is currently unclear whether people, upon becoming infected, will develop mild or severe illness.Yesterday, Mr. Fukuda said that WHO is working to facilitate the process needed to develop a vaccine effective against the swine flu virus, which the agency noted could take around 4 to 6 months, plus more months to build up substantial stocks.Meanwhile, today at the Security Council, which is holding an open debate on the situation of children caught up in armed conflict, Secretary-General Ban Ki-moon reiterated his call for international unity on the swine flu outbreak. “This really requires the whole international community’s cooperation, and I count on the leadership and commitment of not only the Council member States, but the whole international community,” he said. read more

Annan scales back requests to fund Sierra Leone special court

In a letter to the President of the Security Council released today, the Secretary-General says that last month the Secretariat presented to interested countries revised estimates for the Court’s funding needs, amounting to some $57 million for its first three years of work, including about $16.8 million for the first year.The Secretary-General had proposed last October the establishment of a Special Court for Sierra Leone to try persons deemed most responsible for war crimes, crimes against humanity and other violations of international humanitarian law. He said at the time that he would proceed with establishing such a Court only after he had received contributions to finance the first year of its operation and pledges sufficient to fund the next 24 months, which were estimated at $30.2 million and $84.4 million, respectively.As of 6 July, the Secretariat has received indications of contributions in funds for the Court’s first year amounting to about $15 million, and pledges for the following two years for approximately $20.4 million, the letter says.Accordingly, the Secretary-General says he intends to circulate a letter to countries that have made pledges, asking them to deposit contributions within 30 days for the Court’s first-year costs to a Trust Fund.Once the Court is established, the letter says, “Member States have a responsibility to ensure that sufficient resources are available to secure the completion of proceedings against those indicted.” read more

UN mission calls on Sudan Government to end attempts to forcibly relocate

A team dispatched by the UN Mission in Sudan (UNMIS) is on the scene investigating preliminary reports that earlier today, Government military and police forces opened fire on IDPs during an operation in the Soba Aradi squatter area, near the capital, Khartoum, a UN spokesman said.The Government forces are said to have sealed the area in an effort to prevent IDPs from leaving – in line with its aim of relocating them to another location, near an official IDP camp. But UNMIS has also received reports that the security forces opened fire on IDPs who resisted, Stephane Dujarric said at the daily briefing in New York.The Mission’s concern follows a similar incident last week and it said then that the process by which demolitions, relocations and plot allocations was being carried out constituted human rights violations, including forced return. read more

This Google Scientist Learned an Interesting Way to Teach Neural Networks

first_img Watch: Dolphin Leaps Feet Away From Unsuspecting SurferNASA Says 2 Asteroids Will Safely Fly By Earth This Weekend Stay on target Artificial intelligence is as trippy as it gets when it comes to thinking about how machines “think.” But what about when you consider how machines teach and learn from each other? That’s something one Ian Goodfellow dreamt up, as he discovered a way for neural networks to improve themselves and each other by actually teaming up and working together, as amazing and far-fetched as that sounds. As part of the Google Brain Team now, Goodfellow is all about improving the intelligence of computers and removing the need to hand-feed them data to get them started learning on a task.Before his discovery, Goodfellow was previously studying how neural networks can teach themselves real concepts without the assistance of humans, which is a super strange idea when you think about it, but certainly not out of the realm of possibility. While out at the pub one day, Goodfellow was thinking about how neural networks could conceivably work together on one thing. With one network learning about a particular set of data and generating examples while the other would try and determine whether the example was real or fake and would allow the first network to correct and improve itself going forward.After this flash of genius, Goodfellow went home and coded what’s known as a “generative adversarial network,” which would feature dueling neural networks working to perform impressive tasks, by improving the resolution of a pixelated image, create realistic fake photos, use certain filters, and more. All this, apparently from a stint at the pub. Sure, when Goodfellow goes to a pub or to a party he comes back home with million-dollar ideas, and when we come back home we get saddled with hangovers, right? That’s a bum deal. But hey, he’s certainly onto something, and it’ll be interesting to see where this goes.Let us know what you like about Geek by taking our survey.last_img read more

Vancouvers Office Ally to relocate HQ to Texas

Out of the 136 workers the company employs at its headquarters and technical training and call centers in Vancouver, five who work at the headquarters site will move to San Antonio, while the remaining 131 will stay in their current positions.In moving its headquarters to San Antonio, Office Ally also will carry its plans to grow there: O’Neill said he will add 250 jobs in six months as the company opens a new call center and training facility in its new location. He said he expects to complete the move in late November.O’Neill, a self-described “huge anti-tax person,” blasted Washington state’s business and occupation tax — a tax on gross receipts — saying it’s the reason for his decision to relocate Office Ally’s headquarters.“The state of Texas won 250 jobs instead of the state of Washington,” he said.Growing fastO’Neill, a former IBM software engineer, founded Office Ally in 2000. The company, which now generates between $20 million and $30 million in revenues annually, offers health care providers a variety of computerized medical services, including electronic health records and billing for doctors.Under the company’s corporate relocation plans, it will move out of its 10,000-square-foot headquarters in Vancouver and into a 17,000-square-foot facility in San Antonio.

Transistor performance improves due to quantum confinement effects

first_img Citation: Transistor performance improves due to quantum confinement effects (2011, March 21) retrieved 18 August 2019 from https://phys.org/news/2011-03-transistor-due-quantum-confinement-effects.html The team of researchers, Krutarth Trivedi, Hyungsang Yuk, Herman Carlo Floresca, Moon J. Kim, and Walter Hu, from the University of Texas at Dallas, has published their study in a recent issue of Nano Letters.In their study, the researchers lithographically fabricated silicon nanowires with diameters of just 3-5 nanometers. With a diameter this small, the nanowires experience quantum confinement effects that cause the nanowires’ properties to change from their bulk values. Specifically, transistors made with the thin nanowires have improved hole mobility, drive current, and current density – properties that make the transistors operate more quickly and efficiently. The transistors’ performance even surpasses recently reported silicon nanowire transistors that use doping to improve their performance.“The significance of this research is that we have demonstrated that increasing the degree of quantum confinement of the silicon channel results in increasing the carrier mobility,” Hu told PhysOrg.com. “We provide experimental proof of the theoretically simulated high hole mobility of about 3-nm-diameter nanowires.”At first, it may seem counterintuitive that a smaller wire can have a higher mobility than a larger wire. But as the researchers explain, quantum confinement effects increase carrier mobility in the wire by confining the holes (which contribute to the current) to a more uniform range of energy than they have in bulk silicon. Whereas in bulk silicon, holes having a broad energy distribution contribute to the current, in the tiny nanowires, the energy of the holes has a much narrower distribution. Having holes with similar energy, and therefore mass, reduces carrier scattering effects in the nanowires, which in turn improves mobility and current density. By comparing the performance of tiny nanowires to similarly fabricated nanobelts, in which only the thickness dimension is confined, the researchers also show that increasing the degree of quantum confinement of the channel results in higher carrier mobility.

DOI:10.1021/nl103278a As the researchers note, fabricating the high-performance sub-5-nanometer silicon nanowire transistors is relatively simple compared to other methods of nanowire fabrication, which use bottom-up methods and doped junctions or channel doping. One application that the researchers plan to pursue is using the nanowires to make inexpensive, ultrasensitive biosensors, since biosensor sensitivity increases as nanowire diameter decreases. “As required by our funding (NSF Career Award), our immediate plan is to explore biosensing of protein with these types of tiny nanowire transistors,” Hu said. “We believe such small-diameter nanowires with intrinsic high performance can have a major impact on biosensing, as they are expected to provide ultimate sensitivity down to a single molecule with a better signal-to-noise ratio.”In addition to biosensing, the new high-performance transistors could have an impact on CMOS scaling, which is becoming increasingly difficult. The researchers are currently looking for funding in order to explore this area.“These transistors can have an impact on CMOS scaling due to the fact that performance actually increases with decreasing diameter,” Hu said. “Arrays of nanowire transistors with tiny nanowires could be made to achieve high performance without requiring new processing techniques. In fact, the processing can even be simplified over current techniques, as our nanowire transistors do not use highly doped complementary junctions for source/drain; eliminating high doped junctions alleviates many of the current issues in scaling down CMOS processing techniques to the nanoscale.“At large, my personal viewpoint is that silicon still has a lot of potential for nanoelectronics, and the industry may want to consider supporting research in silicon nanowire or quantum wire devices and new architectures to fully unleash the potential of silicon. Everyone is researching graphene, which is a great material of course, but we may not want to ignore the potential of silicon, as we show that effective hole mobility can be over 1200.”center_img A cross-sectional view of a 5.1-nm nanowire, taken with a high-resolution transmission electron microscope.

House to vote on paternity leave benefits for unmarried fathers

first_imgThe House plenum will on Wednesday vote on whether it accepts or rejects the president’s referral of a bill that granted paternity leave and benefits to unmarried couples.The bill – tabled by main opposition Akel – had passed by majority, but president Nicos Anastasiades refused to sign it and sent it back to parliament.The president said the law breached articles 80 and 54 of the constitution.Article 80.2. states that “No Bill relating to an increase in budgetary expenditure can be introduced by any Representative.”The government says extending paternity leave to fathers would incur additional cost to the social insurance fund, and that these extra costs had not been budgeted.Article 54 of the constitution states that only the executive branch of government has the power to direct ‘general policy.’Should parliament refuse to accept the president’s referral, the matter would be litigated at the supreme court.Akel MP and chairman of the House labour committee Andreas Fakondis said on Tuesday his party will reject the president’s referral.Ruling Disy said they will back the president’s referral, while the other parties will reveal their positions during Wednesday’s plenary session.Speaking to reporters, Fakondis said the bill aimed to end the discrimination against unmarried fathers, given that unmarried mothers receive maternity leave.Akel argues that paternity should not be defined as the father being in a marriage or civil partnership, and that therefore excluding those who do not fall into these two categories from the right to paternity leave is discriminatory.In the meantime Akel has tabled another bill that would grant a widow’s or widower’s pension to the spouses of civil servants or employees of semi-governmental organisations, including if the marriage occurred after the retirement of the government employee.At present, the pension is granted to the spouses of deceased persons who were employed in the broader public sector only where the marriage took place prior to the deceased’s retirement.Again, Akel argues that this is discriminatory.Regarding marriages where a man weds a foreign woman, Akel proposes that the women be eligible for a widow’s pension only where the marriage lasted for at least five years to prevent abuse.You May LikeDating Site | Search AdsOnline Dating Sites That Might Surprise YouDating Site | Search AdsUndoEtsyRough Pink Tourmaline 14k Rose Gold Twig Ring, Gemstone Solitaire, Engagement Ring, Anniversary Ring by Dawn Vertrees JewelryEtsyUndoVery FunnyReal Modern Life In Satirical Illustrations Of Israel ArtistVery FunnyUndo Data is the new oil so watch out for mass mining – Netflix filmUndoAt least 20 killed, 50 injured in attack on VP candidate’s office in KabulUndoUrgent work planned on collapsed section of Nicosia wallsUndoby Taboolaby Taboolalast_img read more
