Indian nuclear scientist Homi Sethna has died at the age 86. His death was announced by Homi Mehta, a long time associate of Sethna. The cause of death was announced as lung fibrosis.

During his career Sethna held several posts including director of the Bhabha Atomic Research Centre and chairman of the Atomic Energy Commission. During his time with the AEC Sethna presided over India’s nuclear experiment at Pokhran in 1974.

K. Sankaranarayanan, governor of Maharashtra, said in a condolence message “Dr. Homi Sethna was one of India’s pioneering nuclear scientists, who had played a crucial role in the successful conduct of India’s first peaceful nuclear test in 1974. Even after his retirement, he held many important positions and continued to contribute to the task of nation building. I pay my respects to the memory of Dr. Sethna… and convey my heartfelt condolences to his family members.”

Muslim Somali workers at a meat packing plant in Grand Island, Nebraska wanted to pray. Their colleagues from Latin America wanted to work. A dispute over the company’s break schedule led to formal discrimination claims, mass job walk-offs and public protests by both sides last month, and a reported 200 firings.

Tensions at the plant began after a Federal government raid in December 2006 removed 200 undocumented workers. An equal number of employees quit shortly afterward. Altogether, six government immigration raids at meat packing plants of Brazilian-owned JBS Swift & Co. had removed 1,200 employees from the company’s work force, which caused substantial production problems. Management at the Nebraska plant responded by hiring approximately 400 Somali immigrants who resided in the United States legally as political refugees. Stricter Federal enforcement of immigration laws has had a significant impact on the meat packing industry because few native-born Americans are willing to work in its low-wage factories. Employers advertise to immigrant communities and after the immigration crackdowns the company turned to the Somali community, which was unlikely to be targeted for deportation.

Many of the new Somali workers were observant Muslims who wanted to practice the traditional religious prayer schedule, and few spoke English. The existing union contract had been negotiated before Muslims became a significant part of the factory work force, when religious needs had not been an issue, and break times were assigned according to a rigid schedule to ensure continuous production and prevent workers from working too long without a break. The sharp knives the meat packers wield for their job pose a substantial risk of accidental injury.

At first the Somali workers prayed during scheduled breaks and visits to the rest room. A few Somalis were fired for “illegal breaks” they had spent praying. Rima Kapitan, a lawyer who represents the Muslim meat packers of Grand Island, told USA Today, “they shouldn’t be forced to choose between their job and their religion.” The Somalis offered to let their employer deduct pay for time at prayer, but supervisors considered it unworkable to lose the labor of hundreds of people simultaneously, even if the interruptions lasted less than five minutes.

Plant worker Fidencio Sandoval, a naturalized United States citizen who was born in Mexico, had polite reservations. “I kind of admire all the effort they make to follow that religion, but sometimes you have to adapt to the workplace.” An immigrant from El Salvador was less sympathetic. “They used to go to the bathroom,” said José Amaya, “but actually they’re praying and the rest of us have to do their work.” Raul A. García, a 73-year-old Mexican meat packer, told The New York Times, “The Latino is very humble, but they [the Somalis] are arrogant… They act like the United States owes them.”

Differences of opinion arose over whether the prayers, which are a religious obligation five times a day for practicing Muslims and vary in exact time according the position of the sun, constitute a reasonable accommodation or an undue burden upon non-Muslim coworkers. Abdifatah Warsame, a Somali meat packer, told The New York Times that “Latinos were sometimes saying, ‘Don’t pray, don’t pray’”.

As the Muslim holy month of Ramadan approached during 2007 the Somalis requested time off for religious reasons. Observant Muslims fast throughout daylight hours during Ramadan. Management refused, believing it would affect the production line. Dozens of Somali workers quit their jobs temporarily in protest. Negotiations between the Somali workers and management broke down in October 2007. Some of the fired Somalis filed religious discrimination complaints with the U.S. Equal Employment Opportunity Commission.

Problems resurfaced after September 10, 2008 when Somali workers approached plant general manager Dennis Sydow with a request to start their dinner half an hour before the usual schedule in order to break their Ramadan fast closer to sundown. Sydow refused due to concern the request would slow production and burden non-Muslim workers. During the same month a Somali woman complained that a plant supervisor had kicked her while she was praying. The union investigated the charge and the supervisor responded that he had not seen her while she bent in prayer and had only kicked the cardboard that was underneath her.

Somali workers walked out on strike September 15 and protested at Grand Island City Hall, asking for prayer time. The following day the union brokered a compromise with plant management to move the dinner break by 15 minutes. Plant scheduling rules would have reduced the work day by 15 minutes with resulting loss in pay for the hourly workers.

A Somali worker, Abdalla Omar, told the press “We had complaints from the whites, Hispanics and [Christian] Sudanese“. False rumors spread about further cuts to the work day and preferential concessions to the Somalis. Over 1,000 non-Somalis staged a counterprotest on September 17. Union and management returned to the original dinner schedule. Substantial numbers of Somali workers left the plant afterward and either quit or were fired as a result. Sources differ as to the number of Somalis who still work at the plant: The New York Times reports union leadership as saying 300 remain, while Somali community leaders assert the number is closer to 100.

The EEOC has sent staff to determine whether treatment of Somali workers has been in compliance with the The Civil Rights Act of 1964. Under the law, employers must make reasonable accommodation for religious practices, but the law grants exceptions if religious practice places substantial hardship on an employer’s business.

Doug Schult, the JBS Swift manager in charge of labor relations, expressed frustration at the inability to resolve the problem, which had surfaced in a Colorado plant as well as the Nebraska plant. He told The Wall Street Journal that his office had spent months trying to understand and comply with new EEOC guidelines in light of conflicting pressures. Local union chapter president Daniel O. Hoppes of United Food and Commercial Workers worries that similar problems could continue to arise at the plant. “Right now, this is a real kindling box”.

The Benet Academy Redwings boys basketball team defeated the Oswego High School Panthers 40–34 Saturday night at Benet’s historic Alumni Gym. 

Located at Lisle, Illinois, United States, the gymnasium is home to Benet’s winning streak of 102 consecutive home games. The statewide record lasted from November 26, 1975 until January 24, 1987, when Naperville North High School defeated the Redwings 47–46. Benet also achieved 96 consecutive victories in the Western Suburban Catholic Conference at that time. 

The school continued to use the facility, colloquially referred to as the “Old Gym” or the “Small Gym”, until the end of the 1994 season, when a newer athletic center was built on campus. It wasn’t until the late 1990’s when then-coach Marty Gaughan decided to play one game per year in the Alumni Gym to remind the school of its history. “There is just an electricity, and you feel it when you are in there,” said Gaughan, who coached the team from the 1989–1990 season to the 2007–2008 season. 

This tradition continued until the 2006–2007 season, when the Redwings played against long-time rival St. Francis High School. Renovations prevented the gym from being used for athletic events over the past two seasons. This game was Benet coach Gene Heidkamp’s first opportunity to coach in the older gym. “So much history and winning has taken place there, which makes it so special. It is something the entire school community is excited about,” said Heidkamp. 

Saturday’s game was played at the Alumni Gym at the request of Oswego assistant coach Jim Bagley. He wanted his son, senior forward Chris Bagley, to experience the same atmosphere he had as he played for Benet in the 1978–1979 season. Greg Kwiatkowski was also Jim Bagley’s teammate in Benet, and his son, Joe Kwiatkowski, was in the Panthers’ starting lineup as well. “Two of us who played at Benet together and now our son’s play on [Oswego] together and for them to have a chance to play where we played is going to be a great night and great experience,” said the senior Bagley. 

Alumni Gym apparently still had its charm in the second half for the Redwings, whose 15–17 score at halftime worsened into an 11-point deficit in the third quarter. Benet fell behind with a score of 21–29 at the start of the fourth quarter. From that point, the Redwings’ defense began to kick in. Oswego could make only 2 of its 13 field goals in the third quarter. Benet’s offense also gained momentum as center Frank Kaminsky scored all of his 9 points in the fourth quarter. A shot by senior Mike Runger brought the score to 31–31, and two consecutive driving layups by David Sobolewski gave Benet the lead that would last for the rest of the game. 

“We hit a dry spell there, but let’s give credit where credit is due. Defense wins games and they are the best defensive team we’ve faced all year,” said Oswego coach Kevin Schnable.

Benet’s Matt Parisi led his team with 15 points, and Sobolewski scored 12. Oswego’s Andrew Ziemnik also scored 12.

At least 10% of the increase in Medicare expenditures since the mid-1990s is due to increased rates of one type of elective surgery, according to a recent study, and many of the patients may not need it. University of California, San Francisco found that only 44% of patients who undergo an elective cardiac surgery called angioplasty get the recommended test to determine whether the procedure is appropriate.

As a result, patients may be receiving a procedure that they either do not need or for which the risk outweighs the benefit. The operation opens partially clogged arteries in patients with heart disease and the annual rate of elective angioplasties has tripled in the United States during the last decade.

Angioplasties are currently being performed at a rate of over 800,000 per year in the U.S. The average cost was $44,110 per procedure in 2004. Since the operation tends to be performed on older Americans, Medicare covers most patients and compensates US$10,000 to $15,000 for each case.

Reuters reporter Julie Steenhuysen writes that angioplasty is “big business for medical device makers including Boston Scientific Corp, Medtronic Inc, Abbott Laboratories Inc and Johnson & Johnson”. Dr. Raymond Gibbons, a professor of medicine who specializes in cardiology at the Mayo Clinic in Rochester, Minnesota, criticizes the current U.S. health care system for compensating doctors based upon procedures performed rather than for following recommended practices.

A stress test in which the patient walks on a treadmill is recommended to determine whether a partial obstruction impairs heart function. Although not all patients who need angioplasty are strong enough to undergo the stress test, UC San Francisco researchers were surprised that testing preceded so few of the surgeries.

Professor of medicine Dr. Rita F. Redberg told U.S. News and World Report, “We didn’t expect to find 100 percent, but we expected a much higher percentage than 44”. Dr. Redberg co-authored a report on the findings for the Journal of the American Medical Association this month.

Dr. Grace Lin, another co-author of the study, noted: “What really matters is whether or not that blockage is affecting blood flow to the heart. That is why the stress test is important.” Their research analyzed over 23,000 Medicare cases and over 1,600 commercial insurance cases.

American Heart Association president Timothy Gardner called the study “a good wake-up call” to remind medical doctors to make sure they do not perform unnecessary procedures. Dr. Gardner regards the study as evidence that many unnecessary angioplasties are being performed.

The study found great variation in the rate of stress testing. Geographic areas ranged from 22% to 76% with the highest rate of testing in the Northeastern and Midwestern states. Testing rates also varied by gender, with men more likely to receive a stress test than women, and by other factors including the age of the physician. Dr. Gibbons points to some of these variances as indications that some physicians may be performing angioplasties indiscriminately.

Not all physicians agree. Although the various types of stress testing usually cost a few hundred dollars instead of tens of thousands, the chief cardiologist at University of Wisconsin Hospital and Clinics Dr. Matthew Wolff notes that stress tests yield false negative results in about 10% of cases. In his opinion, doctors who rely on stress tests “are going to be missing people with severe disease.” Although he agrees that some angioplasties are unnecessary, he contends that the new study does not offer a solution to the dilemma.

The American College of Cardiology plans to release new guidelines soon to help doctors determine when a stress test is appropriate, yet the payment system lacks a financial incentive to abide by testing guidelines. Dr. Eric Topol of Scripps Translational Science Institute in La Jolla, California noted the underuse of stress tests in a study of private insurance records 14 years ago. Dr. Topol agrees that testing guidelines “should be much more clear-cut”, and adds that stress tests ought to be performed annually. “You can do a stress test every year to be sure things are normal. That is an important baseline that is being ignored all too frequently.”

Cardiologist, Dr. Anthony DeFranco of Aurora St. Luke’s Medical Center, considers stress testing to be appropriate in at most 65% of cases, since a substantial minority of patients have other health problems that prevent them from undergoing the test.

The iPhone only made its appearance as a prototype and there have been controversies aroused.

The dispute has come up between the manufacturer of the iPhone (which was resented on Wednesday for the first time) – Apple Inc. – and a leader in network and communication systems, based in San Jose – Cisco. The company claims to possess the trademark for iPhone, and moreover, that it sells devices under the same brand through one of its divisions.

This became the reason for Cisco to file a lawsuit against Apple Inc. so that the latter would stop selling the device.

Cisco states that it has received the trademark in 2000, when the company overtook Infogear Technology Corp., which took place in 1996.

The Vice President and general counsel of the company, Mark Chandler, explained that there was no doubt about the excitement of the new device from Apple, but they should not use a trademark, which belongs to Cisco.

The iPhone developed by Cisco is a device which allows users to make phone calls over the voice over Internet protocol (VoIP).

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.”

Parts of the Indian state of Gujarat have been under curfew since Tuesday. At least seven are reported dead, with over 100 buses and dozens of police stations burned, after protests over job quotas turned violent in several major cities including Ahmedabad, Surat, and Rajkot.

The violence is thought to have started after a brief attempt by police to arrest protest leader Hardik Patel, 22 or 21. There have been weeks of protests by members of the Patel caste, with the most recent involving an estimated half a million people.

Ahmedabad, the largest city in the state, has seen the closure of public transport, internet access, schools, and businesses. Ahmedabad is being patrolled by 400 military personnel. The national government has deployed several thousand paramilitary personnel to assist the state government.

The Patel caste, who form up to a fifth of the state population, are generally seen as being affluent businesspeople. However, they want their community to be given the status of Other Backward Class, which would result in eligibility for reserved jobs. They feel they are under-represented in higher education and are suffering in a regional economic downturn.

Amongst those calling for an end to the violence was Prime Minister Narendra Modi, who said “each and every issue can be resolved through talks” during a televised broadcast. He was elected last year and was previously the Chief Minister of Gujarat for more than twelve years. He was in power in Gujurat during sectarian violence in 2002 which resulted in about a thousand deaths.
