Apple expected to unveil new iPhone next week

Apple Inc looks set next week to unveil its much-awaited new iPhone, which analysts say will have a bigger screen and work better with remote computing services.

Apple on Tuesday invited media to a "special event" called "Let's talk iPhone" on October 4 at its Cupertino, California headquarters, an unusual location for a company that typically introduces major products at larger venues in San Francisco.

The invitation did not have any other details, and an Apple spokesman would not provide further information.

"This is the iPhone 5," ThinkEquity analyst Mark McKechnie said of the event.

The new iPhone would be the first major product launch under Tim Cook, who took over full-time as chief executive after co-founder Steve Jobs resigned last month.

It was unclear if Jobs, who is now chairman, will take the stage at the event.

Though a good product, the current iPhone 4 could use some improvements, McKechnie said. "We talked about it having a bigger screen, a dual core processor, and probably integrates pretty well with the iCloud."

The iPhone -- introduced in 2007 with the touchscreen template now adopted by its rivals -- remains the gold standard in the booming smartphone market.

The new model, which some have dubbed the iPhone 5, will have a bigger touch screen, better antenna and an 8-megapixel camera, one source with knowledge of the matter told Reuters in August.

Hon Hai Precision Industries Co Ltd and Pegatron Corp of Taiwan will make the new phone, and have been told to gear up capacity for up to 45 million units in total, the source said.

NEW VOICE FEATURES?
Apple launched the iPhone 4 in June 2010 in black 16 gigabyte and 32 gigabyte versions, and added white ones in April. The company typically refreshes its iPhone lineup during its developer event in June, but delayed the new model this year.

Apple sold 20.34 million iPhones in the third quarter ended June 25, which analysts say helped it vault past Nokia and Samsung Electronics to become the world's biggest smartphone maker.

Some analysts are expecting another version of the iPhone 4 to be launched along with the next model.

"The new (iPhone) 4 will tackle the prepaid market and the (iPhone) 5 will have the A5 chip that's in the iPad and be faster, thinner and possibly with a bigger screen," Colin Gillis, analyst with BGC Partners said. He cited possible voice-recognition features as well.

Shares of Apple rose 0.6 percent to $405.66 on Nasdaq early Tuesday afternoon.

Windows Phone 7.5 Will Mango be the gamechanger?

With over 500 features for the smartphone lovers to delve into, will 'Mango' prove to be a threat for its contenders, Android and iOS?

Although not too popular, O2 Pocket PC, Windows Mobile 2003 SE, Windows Mobile 6.5.5, all testify Microsoft's decade long existence in the field of mobile phones, besides computers. Although the company planned to continue the Windows Mobile line, however, Microsoft decided to create a new mobile operating system platform. Hence, Windows Phone (WP), the upgraded mobile operating system was brought to the limelight in 2010.

Although the reception was generally positive, the product however lacked some of the common features that we have come to enjoy in other smartphone operating systems, like in Android and iOS.

Realising today's consumers' demands and the aftermath of its shortcomings, WP addressed these limitations in an update Windows Phone 7.5 codenamed 'Mango'. The roll out held on September 27, 2011, Mango is a major software update for Windows Phone, to get the major wrinkles of the shortcomings ironed out.

Features that do make an impact on our everyday smartphone experience-- multitasking, social network integration, email and exchange, will finally be incorporated. In short, WP7.5 is precisely what we wish Windows Phone would've been from the beginning -- a platform that's capable of handling all of our needs, no matter how crazy they may be.

A gigantic improvement and one of the favourite features in WP7.5 is its email and messaging feature. It has a linked email inbox that combines multiple email accounts into one consolidated tile, making the system convenient and time saving. With WP7.5 one doesn't have to hunt through hundreds of other messages to find each segment of a conversation, as the full correspondence is grouped together-- an absolute must-have feature in this day and age.

In today's busy life, it's all about 'Glance and Go'. We tend to communicate with our co-workers, friends and family on any social network and trying to keep in touch amidst the busyness. WP7.5's ability to integrate social network content with many of the platform's other key features is sure to be near the top of the list.

The phone is now littered with plenty of ways to communicate via Twitter, Facebook and LinkedIn. Tweets that mention your name are dropped into notifications, and you're given the option of replying to it. WP7.5 also gives you the ability to organise your contacts into 'groups', which by showing live tiles for individual members, notifications and pictures make interaction all the more easier and simultaneous.

It is immensely frustrating when say, we are streaming internet radio and aren't able to keep the music going as we surf the web or perform other tasks on our phones. In WP7.5, this frustration, along with others is rectified. The functionality is all built in so a simple long-press of the button pulls up your most recently opened apps.

For the corporate kiddos who use tasks or to-do lists, embedding our tasks within the WP7.5 calendar might as well prove to be worth its weight in gold. To-dos, included as its own pivot screen inside the app, are fully integrated with your agenda, making each deadline appear as its own event.

As mentioned before, every programme in WP has been enhanced to be more customisable and increase the user's experience, and the camera app is no different. People can now be tagged in pictures by tapping on their face and picking a contact from a list.

Sometimes it's the little things that drive us completely batty. Any person who used an iPhone for the first couple years can relate to the frustration of only having a few ringtones to choose from. With the new WP7.5, one can make a customised ringtone by just changing the song's genre to 'ringtone'.

According to Steve Ballmer, CEO of Microsoft, swapping a platform used by millions with something youthful and fresh isn't going to earn customers and praise overnight, especially when it's a brand new ecosystem that has to start from scratch. But with 'Mango', Microsoft has caught up with Android and iOS in nearly every way, with its feature-laden, user-friendly features. Despite a few criticisms in the beginning, the bright future of Windows Phone is worth wearing shades for!

Physics of Medicine

Dr. Hasin Anupama AzhariMedical physics is the application of physical methods and concepts in diagnosis (examination), therapy (treatment) and prevention of human disease and disability which is associated with the practice of medicine. The traditional areas of medical physics have been obviously shown? in radiotherapy, radio- diagnostic, nuclear medicine and in health physics, but with the recent rapid translation of new physical techniques into medical sciences, the work of physicists is getting essential in many clinical areas, e.g. magnetic resonance imaging (MRI), ultrasound, measurement of the body's electric and magnetic fields, positron emission tomography, pulmonary, physiology, cardiology, neurology, ophthalmology and biomedical sensors and implants.

A medical physicist shall have a degree in a discipline of physical science or MBBS with additional M.Sc. degree in medical physics from a recognized university. The responsibilities of a medical physicist usually include clinical service and consultation, research development and teaching. In a survey (2002) done by the American Association of Physicists in Medicine (AAPM) it was observed that the majority portion (76%) of medical physicists works in radiotherapy, 15% in imaging physics, 3% in nuclear medicine, 4% in health physics, 1% in engineering and 1% in administration. The primary responsibility of medical physicist is clinical (78%), academic (8%), research (5%), administrative (3%), in regulatory (4%) and in product development (2%).

Cancer can be treated in three ways: surgery, chemotherapy and radiotherapy. Surgery is the art, practice or work of treating tumor by operative procedures. Chemotherapy is the treatment with drugs that kill cancer cells or make them less active. Radiotherapy is the use of high energy radiation to treat cancer. Out of these three techniques radiotherapy is the cheapest and most curative and palliative ways for various types of cancer. Usually combined therapy is mostly implemented in certain types and stages of cancer.

In clinical radiotherapy practice, medical physics deals with the therapeutic applications of x-ray, gamma ray, neutron, electron, charged-particle beams and radiation from sealed radionuclide sources on the human body. It is also involved with the associated equipment responsible for their production, use, measurement and evaluation. Another important subject in this field is the image quality in the diagnostic area with its entire production methodology and radiation source. Medical physicists are the partners of radiation oncologists or radiologists in cancer treatment or examination respectively.

The main aim of radiotherapy (RT) is to deliver doses of radiation to eradicate a tumor, while nearby tissues or normal structures should be spared as far as possible. Usually, radiotherapy is based on delivering a uniform radiation doses to all target volumes (Tumor). The uniform dose approach describes the best possible tumor control for the case in which all regions of the tumor have exactly the same biological characteristics and sensitivity to radiation. In the radiotherapy technique a team consisting of a radiation oncologist, a medical physicist, a radiotherapy technician and a medical dosimetrist work together for the treatment of cancer. Out of this team, the main jobs of a medical physicist are planning the calculation and treatment of the prescribed patient dose, planning of the high specialized treatment procedure and maintaining the overall quality assurance for patients and the staff.

Comparing all disciplines of medical physics between other countries and Bangladesh, medical physicists are working mainly in radiation oncology physics and diagnostic imaging physics. Medical physicists hold professional appointments in radiotherapy and diagnostic departments in hospitals and medical centers.

The number of cancer patients is growing day by day worldwide as well as in Bangladesh. The complexity in the radiation therapy treatment of this disease requires more qualified medical physicists. So for a better future for the cancer treatment in Bangladesh, we have to put more emphasis on this subject as soon as possible. We hope that the number of medical physicists will increase in the near future as well as the professional level of competence within the coming 5-10 years.

In Bangladesh the number of cancer patients equals 2000 out of 1,000,000 inhabitants per year. That number of cancer cases needs up to 2 teletherapy machines (e.g. a linear accelerator Linac per 1 million people).According to WHO for 160 million Bangladeshi inhabitants we need approx. 320 megavoltage teletherapy machines, 160 radiotherapy facilities are needed to cover an optimal standard in radiotherapy treatment. This means a minimum of 500 qualified medical physicists are required in the future to satisfy the demand of the country. Until now Gono University has been the only university offering B.Sc and M.Sc courses in Medical Physics and in Biomedical Engineering in Bangladesh.

Did You Know? Which is the world's oldest living tree?

World's Oldest Living Tree -- 9550 Years Old -- Discovered In Sweden

The world's oldest recorded tree is a 9,550 year old spruce in the Dalarna province of Sweden. The spruce tree has shown to be a tenacious survivor that has endured by growing between erect trees and smaller bushes in pace with the dramatic climate changes over time.

For many years the spruce tree has been regarded as a relative newcomer in the Swedish mountain region. "Our results have shown the complete opposite, that the spruce is one of the oldest known trees in the mountain range," says Leif Kullman, Professor of Physical Geography at Umeå University.
