Qatari non-profit organization Gulf Organization for Research and Development (GORD) launched a low emissions car at the 2012 United Nations Climate Change Conference (COP 18) in Doha. The car was designed and developed in Qatar.

Revealed during a press conference at the Qatar National Convention Centre, the car in addition to an internal combustion engine, includes an automotive thermoelectric generator designed to capture waste heat to produce hydrogen. GORD expects the heat waste collecting system to be compatible with any gasoline or compressed natural gas car.

GORD chairman Dr Al-Horr summarised the key concepts of the invention in a statement saying, “Our car produces electricity at no cost by capturing thermal waste energy, reducing costs and eliminating the need for an external source of electricity. Also, bulky compressed-hydrogen cylinders are a thing of the past, as our concept accomplishes the production of hydrogen by using water through fuel cells integrated within the car.”

Most of the energy in Qatari vehicle comes from the the car’s gasoline tank, supplemented by a thin film photo-voltaic panel on the roof. Normally in a combustion engine, chemical energy stored in a fuel, such as gasoline, is converted into heat energy through combustion. This heat energy is then converted into mechanical energy, manifested as an increase in pressure in the combustion chamber due to the kinetic energy of the combustion gases. The kinetic energy of these combustion gases are then converted into work; because of the inefficiencies in converting chemical energy into useful work, internal combustion engines have a theoretical maximum effiecincy of 37% (with what is achievable in day to day applications being about half of this). Of the chemical energy in the consumed fuel used by an internal combustion engine 40% is dissipated as waste heat. However, the Qatari vehicle uses a thermoelectric generator to convert this waste heat into electricity. Such generators are used in space vehicles, and produce electricity when thermoelectric materials are subjected to a temperature gradient, the greater the gradient the greater the amount of electrcity produced. In the GORD vehicle the electricity produced is used to electrolyse potable water to produce hydrogen which can be introduced into the vehicle’s existing fuel system.

The researchers showed that the heat waste collection engine caused a decrease in the car’s emissions, including a decrease of carbon monoxide and nitrous oxide emissions by more than 50%, the fuel efficiency increasing by 20%. On its website, GORD said that the heat waste collector engine is universal, “Any car can be adapted to accommodate the system as it doesn’t alter any electro-mechanical systems”.

The International Air Transport Association (IATA) said on Wednesday that 2009 was the “worst year” that the airline industry has ever seen since 1945.

“In terms of demand, 2009 goes into the history books as the worst year the industry has ever seen,” said IATA boss Giovanni Bisignani. “We have permanently lost 2.5 years of growth in passenger markets and 3.5 years of growth in the freight business.”

According to the group, passenger traffic was down by 3.5% compared to a year earlier, and freight by 10.1%. The group estimated that the airline industry lost a total of US$11 billion in 2009 last year, and will lose another $5.6 billion in 2010.

Airlines in Africa had the biggest passenger demand drop, at 6.8%; North American airlines and Asian carriers had demand go down 5.8%. European airlines saw a drop of 5%. Middle Eastern and Latin American carriers, however, had rises in demand, with gains of 11.3% and 0.3%, respectively. According to the Agence France-Presse news agency, part of the reason Middle Eastern carriers performed better is because of their position between Asia, Africa, and Europe, resulting in more connecting flights through hubs.

“While both North American and European carriers saw demand improvements in the first half of the year, the second half was basically flat,” said IATA.

IATA represents 230 airlines, accounting for 90% of scheduled air traffic, although some budget carriers are not included.

The IATA boss said that, although the worst appeared to be over due to the global economic recovery airlines would have to keep their costs low. “Revenue improvements will be at a much slower pace than the demand growth that we are starting to see,” he noted.

“Profitability will be even slower to recover and airlines will lose an expected 5.6 billion dollars in 2010. The industry starts 2010 with some enormous challenges. The worst is behind us, but it’s not time to celebrate. Adjusting to 2.5 to 3.5 years of lost growth means that airlines face another spartan year, focused on matching capacity carefully to demand and controlling costs,” Bisignani continued.

Costs for security were also an issue. Bisignani said: “Governments and industry are aligned in the priority that we place on security. But the cost of security is also an issue. Globally, airlines spend US$5.9 billion a year on what are essentially measures concerned with national security. This is the responsibility of governments, and they should be picking up the bill.”

Analysts, however, say that cost cutting measures, intended to attract more customers, would also harm airline profits. Saj Ahmad, an independent airline analyst, commented: “Continued fare wars between airlines mean that yields and profitability will be low. Airlines are struggling to fill their airplanes and discounted ticketing has done little to alleviate the pressures on their costs,” as quoted by the BBC.

“Capacity has come out of the global airline system, but until a few airlines perhaps exit the industry through bankruptcy or mergers, there is still a very long road until we see serious stability, let alone growth,” Ahmad added.

New ‘deadly’ sexual enhancement products have been found in Singaporean markets and can cause serious side effects on users.

The Health Sciences Authority (HSA) announced the presence of the illegal drugs, known as Power 1 Walnut, Santi bovine penis erecting capsule, Zhong Hua Niu Bian and fake Cialis, which have been discovered over the past 3 months. Santi bovine penis erecting capsule has been found to contain high amounts of glibenclamide, a potent drug used to treat diabetes. The tablets also contain sildenafil and tadalafil – potent western medicines used to treat erectile dysfunction. Zhong Hua Niu Bian also contains sildenafil and glibenclamide.

High consumption of the tablets can be potentially deadly as the glibenclamide in the capsules can lead to drastically reduced blood sugar levels which can lead to seizures, stroke, coma or death. Consuming half of a Power 1 Walnut capsule has led to unconsciousness and frothing at the mouth.

Consumption of Power 1 Walnut has led to the death of a middle age man last week who fell into a coma. Currently, one death and two cases of coma have been reported from the total of 89 hospitalised cases linked with the consumption of the illegal drugs. It has been revealed that patients obtained the drugs by purchasing them from illegal peddlers located in various parts of Singapore.

The HSA has advised people to stop consuming the drugs and to report on any cases of consumption to them.

A recently created Danish clothing company is selling on the internet T-shirts in order to support the clandestine radio station of the Colombian guerrilla group Revolutionary Armed Forces of Colombia (FARC) and the graphical workshop of the Popular Front for the Liberation of Palestine (PFLP). In fact the money will be used by these groups to carry on their terrorist activities. FARC activities include kidnappings, masacres, bombs, extortions and the drug trade.

Fighters and Lovers is selling the T-shirts at 170 DKK (US$27.6), from which 35 DKK (US$5.7) are to be destinated to support both armed groups.

Anna Duever, Fighters and Lovers PR chief, said to Spanish news agency EFE that their objective is to “defend freedom and social justice, which is FARC and PFLP are fighting for”. Duever believes the fact the FARC has been included by the EU in its terrorist group list is a “political game”. “We pay our taxes in Denmark, and that money is used for financing the troops our government has sent to Iraq. That’s terrorism. Besides, in Colombia there’s a regime oppressing population and torturing and killing its people”, she said.

Colombian Foreign Affairs Minister, Carolina Barco, said to local media that “financing terrorist groups is unacceptable and goes against all the international norms. Yesterday [Tuesday 19] our ambassador contacted the Danish government, we sent a protest note and have demanded an explanation.”

A year ago, a Danish NGO named Oprør (“Rebelion”) stated it had donated money to the Colombian guerrilla. A new antiterrorism law in Denmark may punish it.

Romania’s new road traffic laws have been approved by the Senate, with the laws being in accordance with European Union legislation and updating a previous law from 1999. Romania is currently going through the process of aligning its legislation with EU standards, as it is set to become a member of the European Union on January 1, 2007. The Senate approved the law with several amendments from the original draft drawn up by the government and approved by the Chamber of Deputies.

The new traffic laws include many important changes. Firstly, car drivers with a concentration of 0.80 grams or more of alcohol per litre of blood can receive penalties of between one to five years in jail. In the case of public transport drivers, the punishment can increase to seven years in jail. Additionally, constructions of any kind will be banned on sidewalks, and traders will not be allowed on roads and parking lots.

Another important change is that pedestrians injured while crossing the street in an unauthorised manner, such as at a red light, will “bear full responsibility” for their actions, according to the law.

Before being implemented, the law must be approved by the President, Traian B?sescu.

Indian Ocean – The death toll continues to grow and millions face a homeless life in the new year as coastal communities in south Asia struggle against continued aftershocks and flooding caused by the largest earthquake to strike the planet in more than a generation.

The magnitude 9.0 undersea megathrust earthquake struck off the western coast of Sumatra, Indonesia on December 26, 2004, at 00:58:50 UTC (or 07:58:50 local time in Jakarta and Bangkok).

The earthquake was the strongest in the world since the 9.2-magnitude Good Friday Earthquake which struck Alaska, USA in 1964, and the fourth largest since 1900. More than 140,000 deaths[1] were caused by resulting tsunami, which in Thailand were up to 10 meters (33 feet) tall, and struck within three hours of the initial event.

Multiple tsunamis struck and ravaged coastal regions all over the Indian Ocean, devastating regions including the Indonesian province of Aceh, the coast of Sri Lanka, coastal areas of the Indian state of Tamil Nadu, the resort island of Phuket, Thailand, and even as far away as Somalia, 4,100 km (2,500 mi) west of the epicenter.

While the earthquake and the tsunamis are no longer ongoing (other than aftershocks), the humanitarian and economic crisis generated by the disaster is still ongoing. This report will attempt to cover the crisis as it continues to develop.

At the company’s own Worldwide Developers Conference (WWDC) keynote at the Moscone West center in San Francisco, Apple CEO Steve Jobs introduced the next generation of software products from Apple. Apple unveiled Lion, the new version of their Mac OS X operating system for desktop and laptop computers that brings new features to the software. They also demonstrated iOS 5, a new version of the operating system that powers iPhones, iPod Touches, and iPads. Alongside both announcements, Jobs also announced a new iCloud service to sync data among all devices. All 5,200 participating developers will spend the rest of the week in workshops with Apple employees; developer releases of each product were made available today.

Mac OS X Lion will be shipped in July through the online Mac App Store available on Mac computers for US$29. According to Apple, the update adds over 250 new features to the OS. Employee Phil Schiller discussed new multitouch gestures along with a dynamic task manager named Mission Control that shows open applications. During the keynote, Schiller said, “The Mac has outpaced the PC industry every quarter for five years running and with OS X Lion we plan to keep extending our lead.” It also adds full support for the Mac port of the popular App Store, full screen applications, iOS-style app icon lists called Launchpad, and other iOS-like features including a revamped Mail and Auto Save among others. Mac OS X Lion was announced at a different Apple event several months ago and will replace Mac OS X Snow Leopard, which was released in 2009.

Soon after, the company also introduced the latest installment in its popular mobile operating system iOS. The fifth version (iOS 5) introduces around 200 new features, including a revamped notification system, which combines messages and notifications from all applications installed on the user’s device. Scott Forestall, an Apple employee, also revealed that iOS devices would no longer require a computer for setup, allowing users to ‘cut the cord’ between their devices and PCs. Magazines and newspapers also have a new folder interface; the Twitter social network is now integrated significantly into iOS devices. Improvements to the mobile Safari browser were also announced; tabbed browsing and a Reader feature introduce desktop-like functionality. Finally, new camera features are built in, including the ability to take snapshots from the lock screen, as well as iMessages, a new messaging platform for iPhones and iPads.

CEO Steve Jobs returned to the stage to reveal Apple’s new cloud services offering, iCloud. The service integrates with Lion and iOS applications and syncs data between a user’s iOS devices. For example, calendar events created on a user’s laptop would be sent to their iPhone through iCloud. Apps, books, documents, photos, and more purchased or created on one device will be shared with others. The service is intended to launch in the fall of 2011 alongside iOS 5 and will be available with 5 gigabytes (GB) of storage for 10 devices for free. Earlier this year, Apple opened a 500,000 square foot data center in North Carolina intended to facilitate this new service. Jobs rounded the services off by unveiling a new iTunes feature that mirrors a user’s library in the cloud, allowing them to listen and download music to authorized devices. “We are going to demote the PC to just be a device. We are going to move the digital hub, the center of your digital life, into the cloud,” said Steve Jobs during the keynote. iCloud and iOS 5 will be released in the fall of 2011; Apple announced no new hardware products.

Dr. Stephen Schoenthaler, a Professor of Criminal Justice at the California State University in Stanislaus, has long argued that there is a link between a healthy diet and decreased aggressive behaviour, as well as with increased IQ and school performance.

Dr. Schoenthaler is well-known for a youth detention center study where violations of house rules fell by 37% when vending machines were removed and the cafeteria replaced canned food by fresh alternatives. He summarizes his findings by saying that “Having a bad diet right now is a better predictor of future violence than past violent behaviour.” In a very large test, Schoenthaler directed a study in meals at 803 New York City schools, in low-income neighbourhoods, finding that the number of students passing final exams increased by 16%.

Critics have questioned some of Dr. Schoenthaler findings, due to the lack of placebo control groups. However, more recent work by Dr. Bernard Gesch, a physiologist at the University of Oxford, has placed some of the work on a more scientific footing. Dr. Gesch found that nutrition supplements produced a 26% drop in violations of prison rules over a placebo, and a 37% decrease in violent offences. The Netherlands has embarked on a wider scale dietary research program in 14 prisons.

The short term behaviour consequences of ingesting sugar are well understood: an initial burst on energy, followed a sugar low in which your body produces adrenalin, which makes you irritable and explosive. However, Schoenthaler and Gesch suggest that there are long term impacts over and above the short term consequences of blood sugar variations.
