Do you know the functions of lead sheets?

Lead sheets can be easily bent,shaped and formed for use in many applications.Commonly used medical radiation construction projects,sheet lead can be built into walls,doors and frames to protect medical personnel from gamma rays.It can also be used to stop lead suits for radiation lead suits for radiation leakage from cut-outs and penetrations in lead-lined walls.





Sheet lead is also very effective for waterproofing,soundproofing,and isolating/dampening mechanical vibration.It is highly resistant to environmental and chemical corrosion,and so can be used in nearly any indoor or outdoor application.Lead sheeting is exceptionally versatile and easy to work with,allowing it to be bent,shaped,and cut to suit all applications,with no special tools required.


Acoustical Lead Sheet - Sheet lead is one of the basic materials for acoustic control systems.Lead is an extremely effective and efficient barrier material by itself or fastened to studs as part of a wall.Lead sheet can also be adhesively bonded to gypsum board or plywood.Acoustical Lead Sheet has been developed to help control noise in various interior environments: hospitals,schools,office buildings,industrial plants,apartment buildings and other multi-family buildings.In general,Acoustic Lead Sheet is 1/64"thick and available in many sizes up to a standard roll of 4' x 20'.It's advantages include high density,natural limpness and easy adaptability.

A new measurement campaign in European flat glass products

For understandable public health concerns and environmental considerations,European authorities are keen to ensure that heavy metals,and in particular lead and cadmium,are not substantially present in materials composing everyday life products. Even more important is to ensure that these materials do not release any such heavy metals in the environment or in food or water1.Heavy metals such as cadmium and lead are never intentionally added in soda-lime silicate flat glass,therefore their presence in glass may only derive from traces of naturally occurring circumstances. 
 
To substantiate and quantify this fact,Glass(lead glass) for Europe commissioned an independent institute to undertake an unprecedented measurement campaign on flat glass products from all over Europe. 
This measurement campaign,whose methodology and results are presented on the next pages,confirms that flat glass products produced in Europe contain insignificant amounts of lead and undetectable levels of cadmium. 
All the more,migration levels are so low that,even when using the most precise analytical technologies,most migration results are below the measurable detection limits. 
The lead content ranged from 3.3 to 9.3 mg/kg.Cadmium was always below the detection limit (0.6 mg/kg).To give an idea of the order of magnitude of these values,comparing them with the Dutch soil quality standards2,the content of lead in flat glass is at least 9 times below the target values established for soil.Similarly,cadmium is also well below the target value. 
The migrations of lead and cadmium analyzed by GF-AAS3 were always below the detection limits,2.0 and 0.3 μg/l respectively.As a point of reference,these figures on potential maximum migration are 5 and 17 times below the limits established for lead and cadmium in the European Drinking Water Directive4. 
When addressing issues of lead and cadmium in flat glass products,European decision-makers should carefully consider whether or not additional testing requirements bring any added-value,in light of the insignificance of release and migration shown by this analysis.
Glass for Europe is the trade association for Europe's manufacturers of flat glass.Flat glass is the material that goes into a variety of end-products and primarily in windows and fa?ades for buildings,windscreens and windows for automotive and transport as well as (lead glass window) glass covers,connectors and mirrors for solar-energy equipments.Although in nearly confidential quantities,flat glass is also used for many other applications such as furniture,electronics,appliances,etc.Glass for Europe has four members:AGC Glass Europe,NSG-Group,Saint-Gobain Glass and Sisecam-Trakya Cam and works in association with Guardian.Altogether,these five companies represent 90% of Europe's flat glass production. 
Glass for Europe firmly believes that state-of-the-art glass,such as Low-E insulating glass,Solar-Control glass and Solar-Energy glass can play a vital role in achieving the EU's energy saving targets and promotes ambitious mechanisms to support the market uptake of energy-efficient glass technologies.

Amazing bravery of the tiny girl who pushes her life around in "shopping trolley"

The fact Sienna Roberts is standing at all makes her a mini-miracle,after she underwent critical -surgery which could have left her unable to walk or talk Brave: Sienna Roberts with her ventilator Brave: Sienna Roberts with her ventilator Peter Powell Grinning happily,Sienna Roberts pulls the tiny -shopping trolley that holds her life-saving ventilator.The cumbersome machine must never leave the two-year-old's side,but mum Sara,35,would never dream of complaining. 
 
The fact that the tot is standing at all makes her a mini-miracle,after she underwent critical -surgery which could have left her unable to walk or talk.Just before the op Sara even recorded her then nine-month-old's merry babbling on her phone,fearing she would never again hear the child's cooing voice.But just look at Sienna now – -buzzing around the living room of their Sheffield home pushing the ￡7,000,26lb ventilator and,-amazingly,she has just uttered the words "Merry Christmas”.Single Sara said: "I just burst into tears. I couldn't -believe it – I really thought I'd never hear my daughter say those words."It's the best Christmas present I could ask for,nothing short of a miracle. 
"I was heartbroken when -doctors said Sienna may be bedbound and unable to walk or talk. But without the -operation,Sienna would be unable to breathe."The night before surgery,I recorded Sienna thinking it'd be the last time I'd hear her voice. I played it over and over."Born a tiny 4lbs but healthy,Sienna developed physically a bit slowly so Sara took her to the doctors,also concerned about breathing difficulties.In February last year the medics dropped the bombshell that Sienna's difficulties were due to vocal cords and airways closing down and collapsing.Doctors explained the tot had been using all her energy to breathe and had none left to help her physically.They diagnosed her with three life-threatening conditions bilateral vocal cord paralysis,-tracheo bronchial malacia and subglottic stenosis.The mum of three was warned Sienna's problems are often linked to neurological and muscular -difficulties which experts feared would immobilise her.Doctors said Sienna needed a tracheostomy,when surgeons cut a hole in her windpipe. 
Sara was warned that after the op,little Sienna might never be able to talk,walk or even eat.Sienna underwent the risky and lengthy surgery to fit her tracheostomy and ventilator in February and March 2012 and spent 10 days recovering at Sheffield Children's Hospital's high dependency unit.But within a couple of months the toddler was showing her -determination-proving herself strong enough to crawl and starting to lift herself on to her feet.Sara,also mum to autistic Cordelia,four,and David,19,said: "To see her move about was just amazing."She was much stronger than before the operation. She started toddling after Cordelia,wanting to play with her."With Sienna's increased mobility came the problem of moving the heavy ventilator,which pumps air into her airways and helps her breathing.Initially they used an big supermarket basket then moved to a mini-trolley.Sara said: "Sienna can pull it for a few minutes,then we have to push it as it's so heavy,it leaves her exhausted."But she doesn't mind,she's so used to being -attached to the machine(medical equipments)."Five months after the surgery there was another massive -breakthrough. 
Sienna was staying at the Bluebell Wood hospice in Rotherham for respite care,when she stunned nurses by squealing with delight on a trampoline.Sara said: "I looked around,assuming it was another child,but when I looked at Sienna she squealed again. I couldn't believe it. And I think Sienna had surprised herself."Until then she had used her eyes to show any form of emotion. She looked so startled to hear herself make such a loud noise."At first doctors thought there was a leak in her tracheostomy tubes but,astonishingly,she had learned how to save up breath and vocalise sounds as she exhaled.Sara said: "We were told not even a speech therapist could teach a child to do that. The -doctors just kept telling me how clever Sienna was."In the next few months Sienna learned to say Granddad – as he was always taking food and goodies to the hospital.And,amusingly,her next words were "iPad please"which she uses to play games and has an app that she uses to help communicate.But it was at the end of October that she said "Merry Christmas”.SiennaSparkle.jpg Campaign: Sienna's Christmas Sparkle Sara thinks Sienna was trying to copy Cordelia,who had -continually been singing We Wish You A Merry Christmas.She said: "Sienna can only say up to three words at a time,I think she just managed to get her -favourite part out."Sienna's Sparkle Appeal – the drive to raise funds to her Bluebell Wood hospice where she spends three weeks a year – even -recorded and posted the toddler's moving yule greeting on its website. 
Currently Sienna can only cope for 90 seconds without her ventilator(ventilator machine price) and a team of eight carers work with Sara around the clock to make sure she does not pull her tubes out.She sleeps in a special bed with the machine next to her on a unit and can eat soft food.Doctors still don't know what the future holds but hope that one day they may be able to wean her off the ventilator.Sometimes Sienna's tubes get pulled out when she runs but she always stands still to be reconnect her.Sara said: "There've been a few emergencies when we've been -unable to get her breathing properly and she's been rushed to hospital.Sara said: "But Sienna never complains. She's always smiling and takes every obstacle in her stride."She has defied all the odds already. Doctors thought she would have little quality of life and that I would never hear my little girl talk."To see her running towards me with her ventilator behind her,calling out ‘Merry Christmas'or asking for a cuddle is just fantastic."She's my little miracle. We can't wait to see how she surprises us next."

China's analog X-ray machines are gobbling up US film supply

Film may be going the way of the dodo, but not in China where it's gaining popularity for use in analog X-ray machines (portable x-ray machine)in many of the nation's estimated 20,000 hospitals and smaller clinics. That's led to a massive uptick in business for US-based film exporters, reports Quartz. This year alone, US companies have exported the same amount of film that they did between 2010 and 2012, a figure that could grow even more given the prevalence of these analog machines. Like the digital revolution with film cameras, the same thing has happened with X-ray machines(x ray machines for sale), though Quartz notes that the digital versions are quite a bit more expensive, making the analog versions more attractive in the sprawling rural areas of China. 
 
The film that's being exported comes in large rolls, which can be cut down to be used either in cameras or with medical equipment. More than half of the shipments headed to China in the past year have come from US-based Kodak spinoff Carestream Health, says Quartz, and are being shipped out from ports in California.

Field of gold' scanner cuts children's radiation risk

 
"A new method for scanning children's livers for tumours could prevent them being exposed to unnecessary radiation," BBC News reports. 
The scanner, based on ultrasound technology, successfully identified liver tumours (which are rare in children). 
Usually the liver is initially examined using a standard “grey scale” ultrasound, but this often does not give enough diagnostic information. 
The next option in these types of cases is a computerised tomography (CT) scan. A CT scan involves the use of ionising radiation(lead suits for radiation) that carries a potential, if unproven, risk to the child. 
There is also the option of using an MRI scanner but this is often upsetting to a child (many find the combination of a being in an enclosed space and being exposed to loud noises traumatic) and many children require sedation. 
So an accurate alternative would be a useful advancement. 
The technique being studied is called contrast enhanced ultrasonography (CEUS) and is currently available for use in adults only. It involves using a combination of an ultrasound scanner and a contrast agent. 
The contrast agent "lights up" healthy tissue on the scan-hence the reference to a "field of gold" in the BBC's headline. In contrast, abnormal sections of tissue, such as tumours, appear as black holes. 
The study found that CEUS was highly accurate, agreeing with the diagnoses made by CT or MRI scanning in 85% of cases, with no adverse effects observed. It was able to reliably differentiate harmless from cancerous lesions. 
So far the number of children examined by this technique has been small, though this is unavoidable given the rarity of liver conditions among the child population as a whole. Further study in larger numbers of children undergoing diagnostic imaging for liver lesions is required. 
Overall, the results seem promising.

Two approaches to The IORT programs

In thefirst approach, patients are transported from the OR to the radiation therapy department and the IORT treatment is delivered on one of the department's linear accelerators that normally treats outpatients with external beam therapy.Thus IORT is blended in with the other treatments. 

Figure1.MevatronME by Siemens Medical Systems located in an OR.Note that the machine is a conventional accelerator whose gantry (C-arm) support system is mounted in the end wall.Since the room is slightly oversize for an OR room at this hospital, this still leaves adequate room for surgery. 
In the second approach, IORT treatments are delivered on a dedicated machine.Dedicated linear accelerators are those accelerators that are used exclusively for the treatment of patients through the intraoperative technique.The word dedicated is used here to mean that the linear accelerator, conventional [X rays(x ray machines for sale) plus electrons or electron-only] or mobile, is used exclusively for IORT.It is recognized here that no more electron-only linear accelerators of the conventional, non-mobile type, will be built in the future. 
Dedicated linear accelerators may be located in the OR itself or in a room in the radiotherapy department.If the former, the room is basically an OR that also contains a linear accelerator.
If the latter, it is a radiotherapy room that is equipped as an operating room.The former is preferred since it is part of the total OR complex and the patient does not have to be moved outside the room.In the latter case, the patient undergoes surgery far from the hospital’s main OR and issues of maintaining sterility of the operating area have to be addressed as well as the problem of what to do if a surgical emergency arises for which the satellite OR is not equipped to cope.There are currently very few dedicated units in the OR in the United States; there are slightly more located in the therapy department. 
For the non-dedicated linear accelerator, the need to transport the patient for each case from the OR to the radiotherapy area is a disincentive to the IORT program.For this reason, programs using nondedicated linear accelerators have seen a decline in numbers (see Fig.4).It is highly unlikely that any more dedicated units of the conventional or electron-only type will be installed in the United States in the future for the reasons outlined above.An example of a dedicated electron-only linear accelerator located in the OR is shown in Figure1.The room measures ~6.1 * 8.0m and the unit is mounted into the wall at one end, ensuring an adequate space for surgery.Experience has shown that centers with dedicated OR suites or mobile systems perform more IORT procedures(automatic x ray film processor) than centers that use the patient transport technique.

For the non-dedicated linear accelerator, the need to transport the patient for each case from the OR to the radiotherapy area is a disincentive to the IORT program.For this reason, programs using nondedicated linear accelerators have seen a decline in numbers (see Fig.4).It is highly unlikely that any more dedicated units of the conventional or electron-only type will be installed in the United States in the future for the reasons outlined above.An example of a dedicated electron-only linear accelerator located in the OR is shown in Figure1.The room measures ~6.1 * 8.0m and the unit is mounted into the wall at one end, ensuring an adequate space for surgery.Experience has shown that centers with dedicated OR suites or mobile systems perform more IORT procedures(automatic x ray film processor) than centers that use the patient transport technique.

BIOCERAMICS AS MEDICAL DEVICES

You might heard about what is Bioceramics,howerver ,do you know bioceramics can be use for medical equipments. A bioceramic is a ceramic that can be implanted into a patient without causing a toxic response. Bioceramics can be classified into three categories; resorbable (e.g., tricalcium phosphate), bioactive (e.g., bioactive glass, hydroxyapatite), and nearly inert materials (e.g., alumina and zirconia) (5). A bioactive material is defined as a material that elicits a specific biological response at the interface of the material, which results in a formation of a bond between the tissue and that material (6). Bioceramics can be polycrystalline (alumina or hydroxyapatite), bioactive glass, bioactive glass–ceramic (apatite/ wollastonite, A/W), or used in bioactive composites such as polyethylene-hydroxyapatite.
This article begins with examples of successful bioceramics used clinically that improve the length and quality of life for patients. Developments of porous bioceramic and composite scaffolds for tissue engineering applications are then discussed. The article ends by discussing how bioactive ceramics may be the future of regenerative medicine due to their potential for guiding tissue regeneration by stimulating cells at the genetic level (Fig. 1).

NEARLY INERT BIOCERAMICS
High density, high purity a-alumina (Al2O3) was the first bioceramic widely used clinically, as the articulating surfaces of the ball and socket joints of total hip replacements because of its combination of low friction, high wear resistance, excellent corrosion resistance, good biocompatibility, and high strength (7).
