Green energy on display

Exterior lighting for the summit site was environmentally friendly for optimum energy efficiency, while solar panels and trees were used as sources of renewable energy for the Marrakech summit.

Displays, posters and art installations were made of recycled materials to demonstrate the impact of climate change. Recycling bins were another visible feature of the site. Transport was provided by Chinese electric buses and French Velib bicycles.

Reusable structures

Central to the site were a series of reusable structures, covering 10 hectares. These will be dismantled and used elsewhere.

The Marrakech Hall comprised two wooden structural elements with no sides; however, the centrepiece was an enormous tensile tented structure, translucent and waterproof, that protected delegates from extremes of temperature.

Tensile structures and the environment

Fabric structures can be extremely environmentally friendly. The use of recycled and sustainable materials can create structures that are an energy-efficient and sustainable alternative to traditional roofing.

Several of the original structures associated with the O2 Arena have been dismantled and used elsewhere. These structures have a 50-year life span and have had a useful life in locations across the globe after being reconditioned and weatherproofed.

By maximising natural light and increasing heat and shade protection, the structure in Marrakech demonstrated the sustainability and eco credentials of a tensile structure.

How fabric structures can help you go green

A tensile structure is a highly-efficient structural design that reduces construction costs. If you are interested in these lightweight and sustainable structures, you can find information online about who can help with fabric structures?

There are any number of sustainable elements to a tensile structure – a lower carbon footprint, a reduction in the urban heat island (UHI) effect, and the ability to reuse structures as demonstrated in Marrakech.

Many membranes are free from plasticisers, stabilisers and odours and are chemically inert. Other fabrics can be extremely robust and do not degrade over the lifetime of the structure. The environmental impact can be lessened even further by reusing and recycling fabrics, making tensile fabric structures the architecture of the future – a point the Marrakech structures highlighted.

Are Cancer Drug Benefits Exaggerated by Clinical Trial Results?

Two cancer physicians have spoken out publicly about the way in which large clinical trials can overstate the effectiveness of treatments. The physicians argued in JAMA Oncology that the trials required to obtain federal approval for new cancer drugs regularly make claims that would not apply in real-life situations.

The Background

A contract research organization will often be called on to coordinate clinical trials in order to see whether cancer drugs are safe, effective and worthy of being sold to patients.

The process is based on the idea that such trials would give an accurate insight into how the drugs would work and interact with a general population of cancer patients.

Dr Vinay Prasad, of the Oregon Health and Science University, and Dr Sham Mailankody, of the Memorial Sloan Kettering Cancer Centre, however, have said that the people who take part in such clinical trials are not representative of an overall cancer population.

This is because they are generally healthier, younger and more connected to their health care system. They are also likely to be wealthier and better educated.

In the US, 60 per cent of cancer patients are aged above 65, whilst 31 per cent are over the age of 75. Between 2007 and 2010, clinical trials of cancer drugs such as those run by a contract research organisation saw just 33 per cent of those who took part aged 65 and ten per cent above 75.

During this period, the FDA approved a total of 24 cancer drugs. More information about the FDA and cancer approvals can be found at http://www.fda.gov/Drugs/InformationOnDrugs/ApprovedDrugs/ucm279174.htm.

The University of North Carolina Lineberger Comprehensive Cancer Center’s Dr Hanna Sanoff adds that cancer patients involved in clinical trials are also more likely to have a good support network and be ‘highly motivated’.

Evidence in Support

A 2016 study by Sanoff and colleagues looked at the results of the pivotal trial of cancer drug Sorafenib and the way in which patients who have taken the drug since have fared. One of the major discrepancies discovered was that the median survival of patients in the real world was three months, a significant amount less than the 10.7 months indicated by the trial, while comparable patients who were not given Sorafenib had the same median survival period of three months.

FDA to modernise electronic reporting in hospitals

Future technology will focus on metal adhesive innovations

Innovations in metal adhesives for bonding are likely to increasingly feature in future technologies as part of an upward trend that has already seen them applied in more and more construction and engineering purposes.

Such bonding adhesives offer myriad advantages over traditional methods and are increasingly becoming more effective and versatile as new research and development grows. Read on to find out more about why metal adhesives are likely to be a key part of the technological future of manufacturing.

Innovation

Innovation is ever growing. Where traditional adhesives were once used to bond two metals of the same type, they can now be used to bond different materials with different metals, or metals and other materials, together. Metals that can be bonded these days using adhesive include aluminium, steel and stainless steel, and other materials such as glass and ceramics.

Some people may be wondering what are metal bonding adhesives used for?. You may be surprised by the answer, as they are now used in everything from vehicle manufacture to wind turbines, household appliances and even building construction.

Metal bonding adhesives vs traditional bonding methods

Traditional mechanical bonding methods such as bolting and riveting are limited in where the force can be applied. Adhesive, on the other hand, can be applied to the whole of the two areas to be combined, reducing the stress on specific points and spreading it evenly across the join. In comparison to options such as welding and soldering, adhesives are much more flexible, again giving them greater advantage as a means of bonding. Bonding adhesives are also more energy efficient, lower in cost, and use less human resources than traditional methods. Using an adhesive is also normally a much faster process, both in application and readiness, than traditional bonding methods.

Future outlook

It is thought that the lightweight nature, durability and ever-increasing usability of metal adhesives is likely to see them used more and more in all sorts of technologies and industries. This is an area in which research and development investment is high; therefore, manufacturers can expect to see even more advanced products come their way over the next few decades.

Metal adhesives for bonding are now a key part of manufacturing and processing and are responsible for producing better products, faster and at a slower cost.

The Big Freeze

The Ice Age is a misleading term as there have actually been at least five ice ages in the history of the Earth. An ice age is defined as a time of colder world temperatures and glacial expansion which can last hundreds of millions of years. Humans did not develop until the last ice age, emerging as the dominant land species. An ice age dramatically changes the appearance of Earth as glaciers reshape the landscape and their immense weight pressing into the Earth’s crust. The most recent ice age reached it’s peak about 18,000 years ago. Read more »

The wisdom of teeth

We chew and bite with them, talk with them and smile with them but how much do know about our teeth? Teeth are the hardest substance in the body and are made up of the following:

  • Periodontal ligament – holds teeth against the jaw
  • Cementum – tissue that connects roots to the gums and jawbone
  • Pulp – soft, inner part of the tooth in which the blood and nerves run
  • Dentin – under the enamel, it is a hard mineral substance
  • Enamel – the tough, white part on the outside made from calcium

A normal adult will have 32 teeth made up of incisors, canines, premolars, molars and wisdom teeth. These different teeth are designed to do different jobs. Incisors are at the front and are the sharpest as they need to cut food. Canine teeth are in the corner as they are designed for tearing and grasping. Premolars are next and have a flat chewing surface and the molars at the back are bigger as they are for chewing and grinding before swallowing.

Between six and ten months, a baby’s teeth begin to come through and the process begins again at about age seven. The baby teeth are lost and replaced by permanent adult teeth. Most people have all their adult teeth by 21. It is during the process of getting adult teeth through that it might become apparent that overcrowding or overlapping is an issue. Corrective dental treatment can take place in the form of braces. Metal or clear braces are available. For more information about corrective dental work, visit Docklands dental.

An adult mouth should hold 8 incisors, 4 canines, 8 premolars, 8 molars and 4 wisdom teeth. Unless, of course, you’ve had to have any removed for some reason! Wisdom teeth usually appear at around 18 years of age but are often removed if they cause discomfort and displacement of existing teeth. The crown is the tooth as it appears above the gum line and what is seen when you smile. The root is below the gum line and is the largest part of the tooth but can’t be seen.

According to the dentists, electric toothbrushes are better than manual ones and particularly if they have an oscillating head. Evidence suggests that after a 3 month period, using an electric brush led to a decrease in plaque by 21%.

Soccer Is Helping Young Refugees to Settle into Their New US Lives

Some may call it ‘The Beautiful Game’, and when it has the power to harness confidence and happiness in young refugees never has a phrase been truer. Soccer is being used in the US to help young refugees settle into their new homes with the help of charity Soccer without Borders who run after school clubs all over the country.

The Language Barrier

Many youngsters arrive in the US with minimal or no experience at speaking English. This can make it hard to cope with school, to make friends or to just to get by in general. Soccer is a game that can be played without language. Provided they know the basic rules, boys and girls can join in a game of soccer without worrying about their comprehension or pronunciation of the local language.

Making Friends

For many refugees a feeling of isolation and also of displacement can have a huge effect on how they integrate and develop in their new homes. Football provides an outlet for this, by making the children feel like they are part of a team, allowing them to meet fellow refugees and make friends, giving them a sense of place, identity and belonging.

Soccer Without Borders Incentive Program

Soccer Without Borders is a US based charity that uses football to help young refuges integrate and also develop as individuals. They help children from over 40 different countries of origin. Their incentive programme allows young people to play football provided they attend classes at school. The charity aims to transcend differences and allow for team building to help children grow in confidence, heal from past wounds and integrate with their local community as well as with other refugees. The soccer training itself doesn’t differ from soccer training the world over with youngsters doing soccer drills and given the opportunity to learn from soccer drill videos. The programme goes beyond football to include civic engagement and cultural exchange as part of the program.

Soccer, or football, is played all over the world, with children arriving in the US with a good knowledge of the game. With so many youngsters traumatised by war and coming to the US to attempt to rebuild their lives, this programme is a brilliant way to help them develop and settle into their new home.
