NEU call on Government to 'massively increase' level of testing for pupils to bring coronavirus under control in schools

 I only have anecdotal evidence on Covid19 positive test results in Brent secondary schools so have put in an FYI request to Brent Council for actual statistics.

This is the National Education Union statement released on Friday:

ONS data shows highest rate of infection is amongst secondary aged pupils.
 
The Office for National Statistics' latest infection survey shows that secondary-age pupils now have the highest rate of infection of any age group and, whilst it has fallen a little as a result of the half-term holiday, it is likely to carry on increasing. 
 
The National Education Union has today received a letter from Sir Patrick Vallance and Professor Sir Ian Diamond  in response to a set of questions posed on 20 October.  The letter confirms that ONS and SAGE will be collecting data on school bubbles and ventilation, which is particularly important given the emerging evidence on airborne transmission of the virus. 
 
The NEU is concerned that the continued trajectory of infection rates in schools and colleges will make this lockdown much less effective, and not make the sacrifice worthwhile. Initial indications show that R has not come down far enough - ZOE estimate it to be 0.9, whilst SAGE estimate it 1.0 – 1.2 (see note 4). This indicates that while coronavirus might go into retreat, it will not retreat very far.
This concern is heightened by the SAGE finding that children aged 12-16 played a "significantly higher role” in introducing infection into households in the period after schools reopened their doors to all students. 
 
We are also troubled by new evidence from Public Health England  showing that the positivity rate amongst school-age children is extremely high. For secondary age children it is 18% and for primary age children it is 12%. The level of testing amongst school-age children has actually fallen in recent weeks. This means that only a tiny proportion of pupils with coronavirus are self-isolating. We call on the Government to take urgent steps to massively increase the level of testing for school pupils. 
 
Dr Mary Bousted, Joint General Secretary of the National Education Union, said: 
We are pleased that SAGE has recognised the important role that schools and school-age children play in transmission of the virus . We have been concerned for some time that an erroneous belief that children do not play a significant role in the transmission of coronavirus was badly distorting policy. This is in spite of a clear and sharp trend in infection rates among secondary school pupils in particular since the start of term. 
 
We call on the Government to play a much more active role to suppress the transmission of COVID within schools. Schools have gone to great lengths to make themselves as safe as possible but there is only so much they can do on their own. We put forward a ten-point plan in June with suggestions including hiring additional space and teachers to reduce class sizes.  More recently we have put forward ideas to enable social distancing in schools through the use of rotas for older secondary school pupils.  All these suggestions were ignored. Schools have been given inadequate advice - more often than not delivered at the last minute - and with no additional funding. 
 
The situation is untenable and widespread disruption will continue unless the Government takes steps to get coronavirus under control in schools.

The Gaderbrook flowing freely after today's heavy rain


 Fryent Country Park acts like a giant sponge in periods of sustained  heavy rain. Some of the ponds and ditches overflow dispersing into the meadows and the meadows become saturated. Much of the excess water ends up in the Gaderbrook.

The video above shows the Gaderbrook at its fullest and you can even hear the rush of the water above the noise from the road and the Jubilee tube line.

Barn Hill Conservation Group is working on the banks of the Gaderbrook at the moment.   They are an amazing group who were hard at work this morning, in the rain in the area around Barn Hill Pond.  They are always in need of volunteers so if you want to get plenty of exercise during winter lockdown get in touch. This is what they posted about their work (edited):

GADERBROOK AND PRESTON EASTFIELD

The aim of the work here is to restore this section of the Gaderbrook stream alongside Preston Eastfield.

The Gaderbrook arises from the surface water ditches of the meadows and hedgerows in Fryent Country Country Park.  It also takes surface water from Fryent Way and from parts of the suburban estate between here and Kingsbury Road, That area is due to the countours of the local geology.

Alongside the Gaderbrook, the work aims to reduce scrubeso that the stream receives more light. That should encourage wildflowers and inprove the view of the streamside.

Within Preston Eastfield, a hedgerow will be created (or restored?) from a line of scrub trees, set back from the streamside. On the other side of that hedgerow the footpath is being widened.

The aim? A more attractive path, a hedgerow and streamside habitats.

While we hope that more plants will establish in the improved light, you may occasionally notice that the stream is polluted  (Ed: see last frames of the video). This is due to wrongly connected plambing from propertis that feed into the strean.  If you notice this, please report it to the Environment Agency pollution hotline.

Harrow Go Green 2021 launched - competition for biodiversity awareness and enhancement

 

Bringing you news of an enterprising event in Harrow and one that enables us to look forward at a pretty gloomy time.

A competition for Harrow to raise awareness of, and enhance the borough’s biodiversity

 

Harrow Biodiversity and Environment working with Harrow Council

 

Nature is part of what makes London a special city. In fact, more than 14,000 species of plants, animals and fungi have been recorded here.  Biodiversity is the technical name for the variety of life found in an area - species, habitats and their myriad relationships.  Human impact has caused an enormous loss of biodiversity globally, and this threatens the stability of all the planet’s environments, as well as our own well-being.

 

Think of a golf course, or manicured park.  Biodiversity here is very low: just a few species of grasses, none of which support many other species.  However, the same land managed for a variety of native plants will support many species of grasses and flowering plants which, in turn, support a huge variety of insects and other creatures both above and below ground, which will in turn attract birds and other species.  Biodiversity is much higher and the environment much healthier because of this.

 

Nature affects all of us.  It helps to clean our air, moderates climate change, reduces pollution of all types and manages rainfall.  It improves our health and ultimately saves money.  Diversity in London’s population, as well as its habitats, wildlife and landscapes, characterise many London boroughs.  Harrow is fortunate in that it is especially rich in green and blue spaces.  The richer our local biodiversity, the healthier our nature and environment.  However, more must be done to protect and enhance biodiversity everywhere: not just in nature reserves.

 

Harrow Go Green 2021 seeks to do that. It aims to inform and educate borough residents, children and businesses about the importance of biodiversity.  It will encourage activity which will help to improve biodiversity and our own environment.  Harrow Council is working with the newly formed Harrow Biodiversity and Environment to deliver the competition, a really positive event during these difficult times.  Support is coming from key organisations, locally as well as nationally, including Harrow Heritage Trust, Harrow Nature Conservation Forum, the Green Party, Harrow Nature Heroes, the Conservation Volunteers, PlantLife and Harrow in Leaf.

 

The competition launched in November 2020 and will be open to applications until the end of May 2021.  Projects can be submitted into the following categories:

 

·       Schools and Colleges

·       Best Front Space

·       Junior Projects

·       Best Garden Managed for Nature

·       Commercial Projects and Developers

·       Most Original Idea to Enhance Biodiversity

 

Local businesses are giving fantastic support, providing prizes, special discounts and publicity.  These include Jacques Amand International, Franchi Seeds, Armour Design Studio and Pinner Photography.

 

One competition sponsor is Melcourt Industries Limited, a leading producer of peat-free and sustainably sourced composts and soil conditioners.  They educate commercial gardeners, as well as residents, about the importance of protecting our peat bogs and woodlands.  Many projects in the borough are now utilising these products and making a real change, helping Harrow become a peat free borough!

 

A series of online presentations and workshops will suggest ways in which you can develop your own space, and maybe present a winning project.  Whether its pots on a balcony, an insect shelter, planting a wildflower meadow, selection of plants for insects or a wildlife pond in a garden, every single project DOES make a difference.  The first workshop will be by Stephanie Irvine, a community gardener and project manager for the Orchard Project.  She will help you develop your garden for wildlife, whether it’s a single square metre, or an entire garden.  Next will be Andrew Wood speaking about how to make gardens havens for butterflies, moths and other insects.

 

So please enter the competition, help make a difference in Harrow and raise awareness about enhancing biodiversity.  It does not have to be a complete garden redesign.  Even small projects make a massive difference - whether it’s a clever way of managing rainwater in the garden, creating shelter and habitats, or plantings designed to encourage local wildlife.  Please visit the website to get full details and register.  www.harrowgogreen.com

Brent Council Leader, Muhammed Butt, issues new warning over rising Covid19 rates as Diwali celebrations are curtailed

Today's stats from Covid SymptomStudy  - ZOE

From Cllr Muhammed Butt via Brent Council website

Today I need to share some bad news with you. Confirmed cases of coronavirus in Brent are rising quickly again. This is serious and the human cost is real and truly devastating. We see in the news every day that people are dying from coronavirus, including here in Brent at Northwick Park Hospital. Older people and particularly Asian men seem to be most affected. If you want to protect your loved ones – your parents, aunties, uncles and grandparents – you cannot afford to ignore the rules.

The current national restrictions mean that we all must stay at home, avoid seeing relatives or friends who we do not live with and follow the Public Health Rules. The rules are slightly different to the lockdown earlier this year. Schools and other types of education have stayed open. But the only way to lower the rate of infection in Brent, and protect our freedoms, is to stick to the rules. This is life and death.

This weekend Hindus, Sikhs and Jains will be celebrating Diwali, the festival of lights. Religious festivals and celebrations are such a big part of what makes Brent so special. I know how incredibly difficult the pandemic has been for people of all faiths. Earlier this year, Eid was very different. It’s likely that Hanukkah and Christmas won’t be the same either.

As a person of faith, I feel for you. These celebrations are normally a time when families, friends and neighbours come together. None of us wants to stop seeing our loved ones - particularly at such important times of the year. I know how disappointed many of you who were looking forward to celebrating Diwali with your loved ones, at a time when we need hope and light more than ever, will be. But the terrible reality is that we have got to make hard sacrifices together.

Temples in Brent have decided to remain closed this weekend. I want to thank everyone involved for making this responsible choice. I also want to personally thank everyone who will be celebrating at home and online instead, and wish you a Diwali that brings happiness and joy to you and your family. By staying at home you’ll be helping to protect those closest to you – especially older relatives who may be extremely clinically vulnerable, and are at risk of becoming very seriously ill if they pick up the virus. Although the celebrations will be different, there are still plenty of ways to mark Diwali safely. There is also a virtual Diwali event online

The current restrictions are essential to keep Brent safe, and we must all play our part together. There is no single outbreak in the borough. Instead, we believe COVID-19 is being passed on through community transmission. Most likely, this means people are transferring the virus to family and friends by visiting them in their homes.

So please, stay at home and follow the important Hands, Face, Space guidance. If you do develop symptoms of the virus, stay at home and book a free test straight away by calling 020 8937 4440.

If we all follow the rules and stop the virus spreading among our communities, we will be able to look to better times ahead.

New rapid turnaround COVID testing

Brent has been selected as one of the boroughs that will receive new rapid turnaround COVID tests, which will give results in less than hour. We’re planning to use these initially to protect the most vulnerable groups among our communities, and to maintain critical services. We’re currently waiting for more details from the Department for Health & Social Care about when the tests can be rolled out.

 

William Perkin’s Story – a Sudbury local hero

 Thanks to Paul Lorber for this ‘one off’ contribution to our local history series

 

 

While local history is often just local places, I thought it would be good to write about people, who lived locally in the past, and who made a major contribution. This is a story of a famous inventor who made his home in Sudbury. He made a discovery that propelled the development of chemistry – but he is now largely unknown.

 

 

William Henry Perkin was born on 12 March 1838 at King David Lane, Upper Shadwell, East London. He was baptised in St Paul’s Church – a small church with a tall spire built in 1669 after the fire of London. His early home was demolished a long time ago, but a plaque commemorates the site of his birth and his first experiments.

His father ran a successful carpentry business employing 12 men and the family was reasonably well off. Shadwell at the time was a crowded mixture of slums and artisan tradesmen. Their middle-class status did not prevent the impact of poverty-based diseases that were all around them and William lost both his eldest sister and a brother to tuberculosis. William attended a private school near his home, and had lots of hobbies including photography. At the age of 14 he got all dressed up and took his own photo, seen here.

Like most young people, he had no idea what career he might follow, thinking at first that he would follow in his father’s footsteps and become a carpenter. For a while he had ambitions to become an artist or possibly a musician, as he learned to play the violin and double bass. When he was around 13 a friend showed him some simple experiments with crystals and he became attracted by chemistry and the idea of making discoveries.

 

 

Aged 13, William joined the City of London School not far from St Paul’s. The school offered lessons in chemistry, taught during the lunch hour twice a week, and cost his father an extra 7 shillings (35p in decimal currency) per week. Thomas Hall, the visiting master in charge of the lessons noticed William’s interest and made him a helper with his experiments. By this time his father agreed to build a small chemistry laboratory for William in their home, although George Perkin wanted his son to become an architect, like his brother. 

 

 

William also attended chemistry talks given by Henry Letheby at the London Hospital and lectures by Michael Faraday at the Royal Institution. Chemistry then was looked down on as a serious science in Britain, but owing to Faraday’s efforts, with support from Albert, the Prince Consort (a German), the Royal College of Chemistry was founded by private subscription. The first Director of the new College was also a German – August Wilhelm von Hofmann. In 1853, at the age of 15, William enrolled at the Royal College, although it took a number of interviews with Hofmann before his father was convinced.

 

 

The streets of London were at the time lit by gas light. The gas was derived by distillation of coal but the process created great many unwanted by products – one being a large amount of oily tar. Tar was regarded as waste and there was a problem of how to get rid of it, and all the other by-products including sulphur. Chucking it down the drains or into rivers was one environmentally unfriendly solution. Chemistry was still in its infancy, but it was known that coal tar consisted of carbon, oxygen, hydrogen, nitrogen and sulphur. 

 

 

Professor Hofmann was interested in a substance called aniline. He was keen to create quinine which at the time was the only effective treatment for malaria, then still prevalent in large parts of Europe and quite rampant in parts of England. Britain regarded malaria as the greatest obstacle to more colonisation, and the link with mosquitoes had not yet been established. Quinine was obtained from cinchona bark but was in limited supply and therefore very expensive. William understood the importance of this research and was ambitious enough to try to help find the solution. He did this by undertaking experiments in his makeshift home laboratory – without running water or gas supply.

William Perkin had an inquisitive mind and one of his experiments produced a black powder, which when digested with spirits of wine gave a mauve dye. He stained a piece of silk cloth and found that it did not fade with washing or prolonged exposure to light. But what next? He was just 18, and knew nothing of manufacturing processes. With the help of his brother Thomas, William produced a larger quantity of his new dye and sent a sample to Robert Pullar in Scotland who had recently been appointed as dye maker to Queen Victoria. He received an encouraging response, and in August 1856 Perkin obtained a patent for his discovery.

 

 

Although William wanted to concentrate on research, he hoped that making a living from manufacturing would be a means to that end. As investors were impossible to find for such a new industry, it was his own father who decided to risk all his assets to help finance the project. In the mean-time, samples produced using the new colour were tested and “were well received by the ladies”. 

 

 

As getting a suitable factory site in Shadwell seemed impossible, a ‘meadow’ close to the Grand Junction Canal was found. The six-acre Oldfield Lane site, at Greenford Green near Harrow, was purchased from the owner of the canal-side Black Horse pub. Construction started in June 1857, and despite having to design his own manufacturing process and find sufficient quantities of base material, the factory was built and started producing within six months.

In 1858, Perkin had his application for a French patent refused, because he applied too late and a French dye works copied his process. He felt that all was lost – only for his good fortune to be revived by Queen Victoria who wore mauve to her daughter’s wedding, while the Empress Eugenie, at the time the most influential woman in the world of fashion, decided that mauve matched the colour of her eyes. Paris went crazy for mauve, and the rest of the world followed.

To take advantage of the craze William improved the dyeing methods and devised new ones so the dyes could be applied to calico and paper. Demand grew exponentially and with it his personal wealth. Mauve was the height of fashion for about two years and then the time had come for new colours as the fashion industry took off. 

 

 

In 1859, William married his first cousin, Jemima Lisset, and the couple moved to rented accommodation in Harrow Road, Sudbury (one of the villas between Nos. 797 and 807). Their first son William Henry (junior) was born a year later followed by a second son, Arthur George, a year after that. They moved from rented accommodation to a house of their own, Seymour Villa, also on Harrow Road, which included room for a small laboratory.

 

 

William continued to keep busy running his factory and inventing new colours, including Britannia Violet and Perkin’s Green. He had plenty of competition from others in the UK, but also in France and Germany, as chemists were keen to create new colours to feed the never-ending demand. Perkin also continued with his experiments, and did find a way of improving the dyeing of wallpapers, but also spent time writing scientific papers. Some of the dyes he invented were used to colour postage stamps, including the original mauve from 1881 until withdrawn after Queen Victoria’s death in 1901.

In 1869 a new colour (alizarin, a red dye) which William had created was all the rage, and made great profits. By the early 1870s Perkin had personal wealth of £100,000, a very rich man by Victorian standards. He sold his factory, which he regarded as too small to compete with the large German concerns, in 1873. He’d also had enough of constant legal battles to protect his patents. The sale became acrimonious, but fortunately the Perkin brothers won the court case.

 

 

William’s first wife had died of tuberculosis in 1862 and his father died in 1864. In 1866 he married for the second time. His new bride was Alexandrine Caroline Mollwo, the daughter of a neighbouring family originally from Poland, and the wedding took place at St John’s Church, Wembley. They had 3 daughters, Sasha, Lucy and Nellie, and one son, Frederick.

In 1874, and retired from industry at the age of 36, William built a new home called The Chestnuts, next door to Seymour Villa in Harrow Road, and converted his old house into a large laboratory. Between 1874 and his death in 1907 he published 60 scientific papers dealing with magnetic rotary power and molecular architecture of various chemical compounds.

William was an active Christian, and made a large cart shed near his house available for services, as there was then no church in Sudbury village. He bought some land and buildings on the other side of The Chestnuts, which had belonged to the former Sudbury racecourse. There, in 1878, he built the New Hall, designed for use as both a church and village hall.

Perkin became an evangelical churchman preaching charity, moderation and abstinence from alcohol. He created a working men’s club at the New Hall, but the venture was apparently not a success as the men liked to drink. With “The Swan” on one side, and the Sudbury Brewery and its “Jolly Gardeners” pub on the other, temptation was too great! The New Hall’s Sunday School for children, which he actively supported, was popular however, and his daughter Sasha was among its teachers in these photographs from 1899.

William Perkin received a Knighthood in 1906, exactly 50 years after his famous discovery. In 1907 he received a Degree of Doctor of Science from Oxford University at the same ceremony where Mark Twain was made a Doctor of Literature. Later that year he became ill with double pneumonia and appendicitis. His end was very sudden and Sir William died on 14 July 1907 at the age of 69. He was buried in the graveyard at Christ Church, Roxeth.

Lady Perkin, who died in 1929 at the age of 90, continued her husband’s charitable work. She offered the New Hall to the Wesleyan Methodist Trust at a modest price, and they bought it in 1913. Twenty years on, it became too small for Sudbury’s rapidly growing population, and was demolished to make way for the present Sudbury Methodist Church, which opened in 1935. Sudbury Neighbourhood Centre now stands on the site of the old buildings behind the hall.

Perkin also owned part of the former Sudbury Common opposite the church, which he’d allowed the Sudbury Institute football team to use for their pitch. Sudbury shopkeeper Edwin Butler was a local councillor, and persuaded Wembley U.D.C. to buy it from Perkin’s executors in 1920, to become Sudbury Recreation Ground. Butler became the Borough of Wembley’s first Mayor in 1937, and the following year the Council erected a William Perkin memorial seat, in a small garden at the corner of the open space, to mark the centenary of his birth. The seat was officially unveiled by Miss Sasha Perkin in 1939, on her return from Christian missionary work in China. The memorial seat was sadly lost when the Sudbury roundabout was enlarged.

The Chestnuts was demolished a long time ago, but it was situated where Chestnut Court now sits just off Chestnut Avenue. Further on is Chestnut Grove and nearby Perkin Close (a tiny close with around 20 maisonettes) named in his honour. Another memorial to Perkin, organised by Wembley History Society, was unveiled outside Sudbury Methodist Church in 1956, marking the centenary of his discovery of the first aniline dye.

Perkin’s sons, William, Arthur and Frederick, were also part of his legacy. They became successful scientists making their own contribution, doing research at Oxford and becoming Professors of Chemistry at Manchester and Leeds Universities. The methods Perkin used progressed to creating explosives, painkillers, fertiliser, and medical advances including treating ulcers, use as disinfectant and the earliest forms of chemotherapy. The irony of his invention is plain to see - William was conducting experiments to find a medical application and created a new dye. Today scientists are using dyes to find new medical applications.

 

 

In 1944, over 80 years after William Perkin failed to find a synthetic way of creating quinine, an American scientist finally did so. Just in time, as the drug was essential for the treatment of malaria in the Second World War and the fight against the Japanese.

As lockdown returns Fryent Country Park offers solace and exercise

 

Facing lockdown in the difference circumstances of Autumn and Winter limits opportunities but it is well worth visiting Fryent Country Park, perhaps with a flask of coffee and sandwiches in your knapsacks. There are many different paths to explore and every visit brings something new.

This morning I walked for an hour on part of the Barn Hill side of the park. Easily reachable from Wembley Park Station and the 206 bus route.  There is parking at the top of the road called Barn Hill (not, confusingly, the road called Barnhill Road which is on the Chalkhill Estate).
