On Monday, Australian telecommunications company Telstra has introduced dual carrier HSPA+ standard for broadband Internet business customers in the Next G network. This is the first time this technology is being introduced on national scale. The bandwidths the users can deploy increased into two to three times, with Telstra becoming the world’s fastest national mobile broadband service. The switch started with enabling the service for premium users. After some feedback, Telstra may expand the plan.

The higher speeds for wireless are intended to simplify and ease multitasking of users.

John Paitaridis, Telstra’s executive director, network products and services in Enterprise & Government, said “One of the reasons we decided to launch first to Enterprise And Government and Business customers is that clients are saying that their ability to access applications quicker makes a difference to their business and when they start to equate time savings and doing calculations around productivity it does become a return on investment.”

Telstra Business Group Managing Director Deena Shiff also stated that the efforts aren’t as sudden as it might seem, having feedback of many users as the base.

Australians are telling us they can’t afford to be tied to the desk all day and these new speeds mean they can now access mobile broadband at speeds typically reserved for the office. We have been deploying the high-speed capability in the network since December 2009 and now, with the launch of the new Ultimate USB Modem, these new speeds are available to customers across all capital city CBDs and associated airports, selected metropolitan areas and in more than 100 regional locations. These high-speed zones cover approximately 50 per cent of the Australian population and match the areas of highest customer demand and will make the frustration of waiting around for files to download a thing of the past. In other metropolitan and regional areas, the Telstra Ultimate USB Modem offers typical download speeds ranging from 550kbps up to 8Mbps… Our customers have told us that they want higher speed mobile broadband so they can work more flexibly outside of the office and we are delighted to be the first in the world to offer these new blistering speeds on a national network. The new Telstra Ultimate USB Modem provides customers with the speeds needed to handle large files, multi-task and update cloud-hosted applications effortlessly on the go when they are in a coverage area.

Previous modems were able to reach peak speed 21Mbps, with real life speeds ranging from 0.5Mbps to 8 Mbps. The theoretically expected maximum of the new technology is 42Mbps with user speeds varying between 1.1 and 20 Mbps. The new speed is twice as fast. This is caused by that the dual-carrier “Evolved High-Speed Packet Access” technology allows networks to send and receive wireless data using two channels simultaneously. This technology can be deployed on Next G networks. Telstra switched to them in February, thus making the switch to HSPA possible now.

Telstra delayed the implementation of the new technology until elections end. This decision was intended to avoid wrong interpretation of them by Coalition. Coalition’s claims include that wireless networks can be an alternative to the Labor party “fibre-to-the-home” proposal to introduce more expensive wired Internet. The announcement of the new technology, initially planned on August 25, was delayed, with Telstra spokesman Craig Middleton explaining, “We just didn’t want to feel like we were influencing the [telecommunications] debate.”

The political parties have different plans on development and funds on the Internet. The Labor party aims to spend AUD 43 billion to bring 1 Gbps wired Internet nationwide, and the Coalition plans to spend AUD 6 billion to introduce a variety of improvements including upgrade of existing copper Internet as well as expansion of wireless Internet to support 12Mbps. Opposition leader Tony Abbott has said in the past that Australians shouldn’t assume wireless technologies won’t ever be comparable to fixed-line technology. Telstra’s upgrade shows that wireless broadband is reaching the 100 Mbps minimum speeds promised by Labor’s national broadband network.

Telstra has only 2000 devices which support the new technology. This is why the opportunity to try it out is being given only to the Business plan customers, and they receive it for the same price as they were paying for the previous NextG plan. Since October 5, the device will be available for sale, with the Business customers able to buy it with 75% discount and a prepaid data allowance. The upgrade is expected to cover roughly 50% of the population. This is happening at the same time as one of Telstra’s competitors Vodafone is doubling data download quotas on mobile cap plans.

As some testing showed, real life download speeds reached only about the half of the maximum. Telstra executive director of wireless Mike Wright explained that the predicted figures were the estimates, with real life speeds lower due to interfering environmental conditions: “It’s possible to achieve better than the typical user speed claims, but those claims occur in the ideal network environment with good signal quality. When you’re out on the streets you get a lot of variation where the network is subject to signal quality, your location and the network load.”

According to reports, a man protesting the G20 Summit in London, England has died after collapsing at a protester camp.

Sky News says the man collapsed on the street inside a camp close to the Bank of England and when found he was still breathing, but efforts by paramedics to rescue him failed and he was pronounced dead at an area hospital. The name of the person and cause of death are not yet known, but several people were injured earlier in the day. The police claim that protestors threw bottles at them while trying to rescue the protestor.

The London Ambulance Service reported that “we received a 999 call at 7:24 pm from a member of the public reporting that a man had fallen over and was unconscious, but was breathing. [They] made extensive efforts to resuscitate him both there and on the way to hospital.”

Earlier in the day a minimum of 20 protesters broke into the bank and according to reports vandalized furniture, broke windows and cut the telephone lines to the building.

This week, the Public Broadcasting Service aired a NOVA program titled “Dimming the Earth”, which presented research by leading scientists on the complex systems of our global climate and human activity’s effect on it. One of the largest interactions (or “inputs”) humans have with the atmosphere is the ever-increasing use of fossil fuels. Consumption has risen 2% per year for this decade.

Fossil fuels burnt in factories and automobiles send their waste into our atmosphere in two forms. The first is CO₂ and other greenhouse gases, which have received substantial attention in the last few years because of the way they trap heat in the atmosphere. The second is the tiny particles of sulfur dioxide, soot and ash, which scientists call aerosols (basically smog). Research into understanding the negative health effects of air pollution has resulted in the development of catalytic converters for cars as well as devices to remove particulate solids from industrial waste before it reaches the air.

More recently, atmospheric scientists have come upon the phenomenon of the reduction of direct sunlight reaching Earth’s surface— observing a nearly a 5% decline between 1960 and 1990, with evidence of a recovery since then. This has been dubbed the “global dimming” effect, and is probably due to the way these aerosols act upon clouds. It is important to realise that this does not represent a net loss of this much sunshine to the climate system – if so, large temperature declines would have been observed. Instead, the sunshine is absorbed elsewhere in the system, with a much smaller net loss.

Clouds form when moisture gathers around airborne particles, such as pollen or dust. Clouds formed by the aerosol particles emitted by fossil fuel consumption are made of many more tiny droplets than “natural” clouds. These smog-created clouds have two notable effects: they shield sunlight from reaching Earth’s surface and, due to water’s reflective nature, the millions of tiny droplets suspended in them reflect light back into space, allowing even less light to reach Earth.

Many scientists now believe that global dimming caused by these pollutants has mitigated the temperature rises brought about by global warming. Over the last thirty years, Earth’s temperature has increased by about 0.5 oC.

In the absence of global dimming, however, the Earth might be 0.3 oC warmer than it currently is, suggesting that a “tug-of-war” exists between greenhouse gases and particulates released by burning fossil fuels. Efforts to mitigate the human health dangers of smog have allowed more heat into our atmosphere and brought about a sharper increase in global warming.

Dr. James E. Hansen, professor at Columbia University and the head of the Goddard Institute for Space Studies [1], believes that if we continue on our current pattern, this warming could be as much as five degrees in the next thirty years and ten to fourteen degrees over the course of the century. Such a temperature rise would devastate life on Earth, likely bringing on a cascade of self-reinforcing warming effects. Earth’s forests drying and burning, a steady thawing of the Greenland and arctic ice sheets, and, most dangerous of all, a release of the methane hydrates that are now frozen at the bottom of the oceans, could remake the planet into something inhospitable to human life. Dr. Hansen warns that, according to his research, man has just 10 years to reduce greenhouse gases before global warming and other responses to human activity by Earth’s climate reach a “tipping point”, becoming unstoppable.

A school in Melbourne, Australia has experienced a backlash from the public for changing the last line of Marion Sinclair’s iconic Australian folk song Kookaburra Sits in the Old Gum Tree from “Laugh, kookaburra, laugh, kookaburra, gay your life must be” to “fun your life must be”.

Gary Martin, principal of Le Page Primary School in Melbourne, claims that he changed the lyrics as he thought that “the kids will roll around the floor in fits of laughter” upon hearing the original lyrics. Martin wanted to reduce classroom disruption by omitting the word “gay”, here used to mean “happy”, as it was also commonly used as a playground insult. “For example, if a boy is not particularly good at sport, they will refer to that child as gay,” he continued.

Martin told the Nine Network, “I wasn’t trying to incite or insult gay people, [..] it was just a decision at the time that I thought would minimise a disruptive atmosphere with grades one and two”.

From the middle of July, Sony Corporation refreshed their senior laptop brand VAIO from “Video Audio Integrated Operation” to “Visual Audio Intelligent Organizer”. According to Sony Taiwan Limited, this refreshment is an attempt to relocate the laptop consuming market for business and entertainment factors.

In the “VAIO Experience 2008” press conference in Europe, Sony promoted their new product series for different populations including BZ for business, FW for home entertainment, Z for ultra-slim, and SR for complex applications.

Different with past series, Sony added “Clear Bright” screening technology for high-definition display, and “full-carbon production” features. BD-burning and Intel Centrino 2 processing technologies will be featured in all the new models. For security issue, Sony also embedded fingerprint system to prevent personal data to be stolen. Continued from TZ series, innovative designs including “Green Power Button”, “Situational Switch” are also added in newly-launched series.

“Due to consuming market differences, Sony only promoted BZ series in Europe and America but not included Asia. Although the TICA Show in Taipei will be different, functionality will be the greatest issue when a consumers choose a notebook [computer] before buying.” addressed by executives from Sony Taiwan Limited, during the “VAIO Experience 2008” press conference in Taiwan.

In November 2007, a twin-engine 30-year-old Piper aircraft lost all electrical power on board shortly after departing from Kerry airport in Ireland for a flight to Jersey. Without any electrical power, the pilot was unable to use his radio to contact air traffic control. He was briefly able to re-establish contact with the tower using his cell phone, but that was also disrupted.

The report into the incident published on August 6 revealed how a quick-thinking air traffic controller in Cork started sending directions to the pilot by text message. With this assistance, the plane, with five people on board, landed safely after the undercarriage was lowered manually and air traffic control visually confirmed that it was down. Prior to lowering the undercarriage, the first officer noticed that the nose wheel had failed to retract fully and was actually at half its travel.

“In this incident the positive and proactive initiative of the ATC controller, who, on realising that mobile audio communication from the pilot was intermittent, quickly switched to texting his instructions instead”, said John Hughes, an air accident investigator who reported on the incident. “This contributed to the safe resolution of the incident and, for such, the controller should be commended for his actions.”

The pilot, aged 39 and with 1,900 hours of flying experience, succeeded in climbing to an altitude of 6,500 feet without any problems, but needed to communicate to ensure a safe landing. He originally attempted to contact Kerry airport, and after that failed he made attempts to contact Cork.

The report found that the loss of electrical power was due to the aircraft’s alternators failing to maintain the required voltage, probably due to the battery voltage being insufficient to excite the alternator’s windings. The relay may have been in poor condition after having been subjected to a heavy load following take-off, possibly contributing to the incident.

In the German DFB-Pokal final, on Saturday, Munich-based football club FC Bayern Munich defeated rivals Borussia Dortmund 4–3 in a penalty shoot-out decider as the match ended 0–0 after 120 minutes at Olympiastadion in Berlin. This marked the third consecutive loss for Dortmund in the German Cup final. This was the eighteenth German Cup win for Bayern and eleventh domestic double.

Bundesliga winners Bayern Munich had 70% ball possession in the game and had seventeen shots while Dortmund hit just nine. With a total of seven yellow cards shown in 120 minutes, 35 fouls were committed.

Dominating Bayern faced a shot from Pierre-Emerick Aubameyang which was saved in the 85th minute. Erik Durm’s sliding tackle saved a goal for Robert Lewandowski’s shot in the fourth minute of the extra time.

As normal time ended goal-less, the match progressed to additional time. Roman Bürki delayed the Bavarian victory by disallowing Douglas Costa’s 113th minute shot as well as David Alaba’s shot in the next minute.

In the penalty shootout, Manuel Neuer saved Sven Bender’s spot kick, and Sokratis Papastathopoulos missed while Joshua Kimmich failed to score for Munich.

In the end, Munich won the cup defeating their rivals 4–3 on penalties. This match was the last match for Dortmund for their captain Mats Hummels as he is due to move to Munich next week.

In a pre-match conference, Thomas Tuchel, Borussia Manager, said, “Once you’ve reached five finals over the course of five years, simply reaching the final is no longer enough!” ^{((de))German Language: ?Wenn man fünf Mal in fünf Jahren in einem Endspiel steht, ist eine Final-Teilnahme nicht mehr genug!}

Dortmund has won the DFB-Pokal three times. Including the 2012, 2014 and 2015 DFB-Pokal finals they have featured in five finals in the last five seasons in various competitions including the 2013 UEFA Champions League Der Klassiker final. This was Pep Guardiola’s seventh trophy with Bayern Munich in his three years as the club manager. He won the Bundesliga title each season and he is set to join Manchester City next season.
