|SCANNING LINE INTERPOLATING DEVICE AND SCANNING LINE INTERPOLATION METHOD - An interpolation processing section determines a pixel value of an interpolation-target pixel by a diagonal interpolation process. An interpolation value limiting section compensates the pixel value determined by the interpolation processing section such that it becomes a value between pixel values of two adjacent pixels above and below the interpolation-target pixel.

Depending on a judgment result by the intersection area detecting section, a selecting section selectively outputs a pixel value determined by the interpolation processing section, or a pixel value compensated by the interpolation value limiting section, as an interpolated video signal.

From Canberra, Australia:
I am a 38 year old healthy female who was diagnosed with type 1 diabetes five weeks ago, and I had excessive thirst, weight and hair loss. The hair falling out was not in clumps, but excessive amounts in my hairbrush and after washing.
I have been on insulin since the diagnosis and feel that I am back in great health, but my hair is still falling out, although not quite as much. Will this ever stop? I don't want to end up bald! I know this is not an uncommon symptom of diabetes, but nobody can tell me what causes this.
It is highly likely that your hair problem will correct itself soon. The loss of hair during times of stress or illness is a nonspecific problem.The mechanism for the hair loss is usually the premature release of hair from the hair follicle. This results in a generalized thinning of the hair. The cycle for hair growth and recovery is slow to evolve so a lag phase in your recovery is not unusual. Hang in there. I suspect it will improve soon.
[Editor's comment: Hair loss can also be a sign of a thyroid disorder. Check with your doctor to be sure you have been tested for this. SS]

Asbestos testing complete at North Melbourne demolition site
Extensive testing for asbestos on a demolition site in North Melbourne has been undertaken.
Extensive testing for asbestos on a demolition site in North Melbourne has been undertaken.
Work on demolishing a partially collapsed wall at a site in North Melbourne is expected to begin tomorrow.
WorkSafe is currently investigating the circumstances surrounding the collapse of a wall at a demolition site in North Melbourne.
A construction company was fined $30,000 over an incident in which an employee was seriously injured after falling eight metres through unsecured metal sheeting.
A man has died after an incident at a paper recycling plant in Dandenong south on Saturday.
A man has died after falling from a height at a business in Dimboola, in western Victoria on Tuesday.
Two companies were fined a total of $1.5 million in the Supreme Court last week over the death of a worker who fell 40 metres when a piling rig collapsed at a Melbourne construction site in 2011.
A woman has died after the truck she was driving fell into a quarry at Nyora, in South Gippsland on Tuesday.
A man died when he fell 20 metres down a lift shaft at a construction site in Carlton yesterday.
The decision today by the County Court to convict and fine a Melbourne sign writing company $250,000 over its role in the collapse of a wall in Swanston St in 2013 that killed three pedestrians reflects the serious nature of the charge.
Following a comprehensive investigation, WorkSafe has charged the Hazelwood Power Corporation Pty Ltd with 10 breaches of the OHS Act 2004 in relation to preparedness for the fire which took hold in the Hazelwood open cut coal mine on 9 February 2014.
A Malvern hospital was fined $50,000 without conviction after an incident in which an elderly woman was injured when knocked to the ground by an overfilled waste bin.
The sentence imposed today by the Melbourne Magistrates' Court in relation to the Essendon Football Club is a warning to every Victorian employer that they must provide a healthy and safe workplace for their employees.
A man who died last weekend after the tractor he was driving rolled into a dam has now been confirmed as Victoria's third workplace fatality of 2016.
The tragic deaths of a 24-year-old electrician and a 21-year-old dairy farmer at work this week are a horrible reminder to all Victorians why workplace safety needs to be everyone's priority.

PLANO, TX --J.C. Penney Co. has stopped selling a T-shirt for girls that says "I'm too pretty to do homework, so my brother has to do it for me."
Critics, in an online petition drive, complained to the Plano-based retailer that the white, long-sleeve shirt is offensive and portrays a negative stereotype of girls.
Penney on Wednesday apologized and said the T-shirt did not deliver an appropriate message.
The company, which Thursday reported revenue at stores open at least a year dipped 1.9 percent in August, said its merchandise is meant to appeal to a broad customer base and "not to offend them."
The T-shirt was offered for sale online, meant for girls ages 7 to 16. The phrase on the front, in colorful letters, was accompanied by hearts.

On one of the many times I visited the Belanglo State Forest, south of Sydney, Australia, a priest stood in a shaft of sunlight in September 1992 and told a small group of people, including the parents of two British women whose bodies had been found there, that they had gathered to cleanse away evil.
Something wicked had happened there, but evil, said the priest, did not have the last word. No-one knew that not far away the bodies of five other young backpackers lay undiscovered – until they were found a year later. But that, police were convinced, was all. Road worker Ivan Milat was arrested, convicted and sentenced to seven life sentences.
But evil has persisted. Another body has been found. The skeleton of a woman. The forest is refusing to allow us to forget Milat's deeds, although we do not know yet whether this still-unidentified person is another of his victims.
From his jail cell Milat, now 65, is taunting police by refusing to reveal whether he has a hand in the death of the woman, whose body was found just outside a vast area that police had searched in the early 90s after the last of his seven victims had been found.
The priest's ceremony among the trees all those years ago had been conducted for the memory of Milat's latest captives, British women Joanne Walters and Caroline Clarke, both 22. Lying undiscovered for another year were the bodies of James Gibson and Deborah Everist from Melbourne; Gabor Neugebauer and Anja Habschied from Germany; and Simone Schmidl, also from Germany.
Milat was eventually arrested after British backpacker Paul Onions managed to escape from his vehicle and give police details of his attacker – although it was several months before they moved in on Milat's house and took him into custody.
Police always suspected Milat had killed more people who have been
reported missing, but no other bodies were found in the Belanglo
forest – until the dramatic discovery last Sunday of yet another skeleton by a group of trail-bike riders.
Local detectives have formed Strike Force Hixson to investigate the
discovery and are being assisted by the New South Wales Homicide
'The investigation is still in its infancy and it's early days and
far too soon for us to know exactly what's happened,' said
Superintendent Quarmby.
'Obviously there is a lot of speculation surrounding this discovery
but we definitely will not be jumping to conclusions. There are many
lines of investigation to explore.'
And so we wait. We wait for the autopsy, we wait for an identification, we think of the family and friends who will eventually learn that the woman in the forest is one of theirs. And we wonder, too, if the forest will offer up even more of its dead…
One Response to Did Serial Killer Ivan Milat Murder an 8th Victim? We Might Know Soon.
Geez, that's unbeliebvale. Kudos and such.
