How To Cool Hot Classrooms

By P Hunter

Three quarters of teachers said classrooms were too hot to work and learn properly in. They have renewed calls for improved regulations to limit classroom temperatures.

This has been in response to a recent consultation by the UK Department of Education (DofE) on proposed changes to school premises regulations, launched in early February 2012. The NASUWT, the largest teachers union in the UK, has called on the government to improve rules on both ventilation and temperature.

A temperature monitoring study was carried out last June and July across the UK. It revealed that more than three quarters of teachers experienced classroom temperatures in excess of 24C for more than a quarter of a period. Incredibly, a 1/3 experience temperatures exceeding 30C!

The world health organisation (WHO) believes any temperatures above 24C starts to affect productivity as well as concentration. It is no surprise teachers believe these higher temperatures have an adverse impact on teaching and learning.

Many schools have now installed air conditioning to cool overheating classrooms and it is considered the best long term solution. But although the cost of this is often not as high as many Headteachers imagine, increased spending cuts leaves many schools with very little money to install such measures. Listed below are some low budget measures which may cool classrooms without the need to invest in air conditioning equipment.

1. Minimise activities that involve movement during the warmest parts of the day, as this creates heat that will build up in the classroom space. For example, if the sun enters the room during the afternoon then do art projects in the morning before the sun enters the room.

2. Check to see if any heating appliances are switched on in the classroom. A radiator might have been left on and be heating the room without you knowing. [/li]

3. Keep the classroom doors open. Reduce the heat building up in the classroom by letting it out through the door.

4. Attach blinds onto the windows to provide shade to the classroom. Heat reflective blinds are particularly good at reflecting the suns rays back.List Style

5. Position four electric upright fans around the perimeter of the classroom and point them towards the centre of the room. Set the movement of the fan’s head to oscillating so it rotates from left to right, to cool a larger area of the classroom.

6. Switch off computers, televisions or other heat generating devices that are not being used.

7. Create areas of shade in the classroom. Do this by putting large potted plants around the classroom. This will cool these specific areas for added comfort.

If you have any other clever ideas to help reduce over heating classrooms please let us know. Air conditioning can be cheaper than many think, but it does involve cost and possibly disruption to classes and classrooms, and often needs to be installed during school holidays or at weekends. The approximate cost for most classrooms is around 4000 to 6000 depending on orientation and number of pupils.

Bangladesh security tightened following Pilkhana massacre and Bashundhara City fire

Friday, March 20, 2009

Following the Pilkhana massacre which occurred February 25 and 26 leaving 74 dead and the inferno at the Bashundhara City shopping mall complex March 13 leaving seven dead, Prime Minister Sheikh Hasina said security measures are being tightened countrywide across Bangladesh.

Fire drills will be enacted at all key-point installations (KPI). Fire fighting systems will be examined by the fire brigade and the public works department (PWD) to ensure functionality. Security measures will be enhanced supplementing areas under private security such as at the Bashundhara City Complex.

The Fire Service and Civil Defence Department requires modernization and needs new equipment to fight fires past the sixth floor of buildings. The Fire Brigade says it needs turntable ladders, snorkels, foam-tenders, lighting units, emergency tenders, fireproof uniforms, and rescue ropes for fire fighting and rescue operations. Transportation to fires is also an issue due to narrow roads, low electrical wires and congestion.

The Bangladesh National Building Code requires fire fighting equipment installed in buildings over seven floors. This code is to be monitored by authorities to ensure compliance with the new guidelines and to make sure buildings are being maintained.

The Bashundhara City Complex opened Monday for shoppers two days after Friday’s blaze. A probe is underway to determine the cause of the fire and to assess structural damage.

Loss of life was minimized as the blaze broke out on a Friday, the beginning of the weekend in Bangladesh, so offices in the upper floors were empty. The lower eight floors are used for shopping and the upper floors are all Bashundhara Group offices.

The mall is valued at Tk 7.0 billion (US$100 million). It is not known if the complex is covered by fire insurance.

It is estimated that it will take over two years to rebuild the area damaged by flames which were burned down to a skeleton. Bashundhara City’s technical advisor, Latifur Rahman, estimated damages at Tk 2.0 billion (US$29m).

Only one television cameraman has been allowed in to film the burnt area. None of the 2,500 shops, cinemas or cafes were burnt by the inferno. The seventh and eighth floors still experience smoke damage, and there was water damage to merchandise.

A three member committee is currently investigating the cause of the fire which will consist of Iqbal Khan Chowdhury, joint secretary of the ministry, representatives of the police, IGP Noor Muhammad, and fire brigade, Director General Abu Nayeem Md Shahidullah. The committee is required to report within the week with their findings. The forensics department is also sifting through the burnt remains.

The Dhaka Chamber of Commerce and Industries has also formed a committee which has begun interviewing witnesses and recording their testimony alongside the government committee.

It has been discovered that 150 closed circuit cameras were not being used when the fire started. Another mystery is why the mall fire fighting system has been found unused.

Why the fire burnt so fiercely is a matter to think….These matters seem to be mysterious

“In the shopping mall there is an ultra-technology elevator which runs even without electricity but we have found that locked,” Iqbal Khan Chowdhury, joint secretary (Police) of the home ministry, said. “Why the fire burnt so fiercely is a matter to think. We have to see if there was any incendiary substance there. These matters seem to be mysterious.”

Mall management has been asked to submit substances and items which would have been in the upper floors when the fire started. The fire erupted on the 17th floor and spread quickly to the two floors above and engulfed the three floors below. The aerial ladders belonging to the Fire Service and Civil Defence reached as high as the 13th floor of the 21-storey building.

Videos have been sent to the United States (US) for examination to assist in determining the cause of the fire and to help in the damage assessment. Experts from the US are expected to arrive soon.

Firefighters were brought to the rooftop of the 20-storey tower by helicopter. The only fatality in this operation was Baki Billa, a firefighter of Bashundhara City firefighting department, who fell when climbing down a rope from a helicopter to the roof of the building. Three other firefighters made the transition safely. At this same time, the chief security officer was safely rescued by the Bangladesh Air Force helicopter, a Bell 212. Six security officers of the complex also lost their lives.

Mumbai officials demolish 39K shanties; 200K homeless

December 25, 2004

Officials in Mumbai, India, demolished over 6,000 shanties today in a push to eradicate the capital city’s slums. In total, 39,000 shanties have been flattened, displacing over 200,000 people, in the city’s biggest-ever demolition drive, which began in early December.

When complete, over 2 million people are expected to be displaced. After wiping out the least desirable shanties, next in line for demolition are the illegal ‘well-off’ shanties and neighborhoods, according to the legal and bureaucratic motions that have been executed toward cleaning up Mumbai’s appearance by lowering the dominance of shanties, which make up 62 percent of Mumbai’s housing.

“As far as eye can see, there are mounds of wood, tin and tarpaulin, the remains of 6,200 illegal homes, flattened by a heavy excavator running on tank-like tracks and giant motorised claws,” the Indian Express reported about today’s destruction. [1]

Chief Minister Vilasrao Deshmukh said that citizens would see a change within six months. “Every chief minister likes to be remembered, and I’m no exception,” said Deshmukh, who despite having an empty exchequer, also announced that Rs 31,000 crore will be spent on new roads, sea links and rail lines.

Wikinews interviews 2020 Melbourne Lord Mayor Candidate Wayne Tseng

This article mentions the Wikimedia Foundation, one of its projects, or people related to it. Wikinews is a project of the Wikimedia Foundation.

Thursday, October 22, 2020

2020 Melbourne Lord Mayor candidate Wayne Tseng answered some questions about his campaign for the upcoming election from Wikinews. The Lord Mayor election in the Australian city is scheduled to take place this week.

Tseng runs a firm called eTranslate, which helps software developers to make the software available to the users. In the candidate’s questionnaire, Tseng said eTranslate had led to him working with all three tiers of the government. He previously belonged to the Australian Liberal Party, but has left since then, to run for mayorship as an independent candidate.

Tseng is of Chinese descent, having moved to Australia with his parents from Vietnam. Graduated in Brisbane, Tseng received his PhD in Melbourne and has been living in the city, he told Wikinews. Tseng also formed Chinese Precinct Chamber of Commerce, an organisation responsible for many “community bond building initiatives”, the Lord Mayor candidate told Wikinews.

Tseng discussed his plans for leading Melbourne, recovering from COVID-19, and “Democracy 2.0” to ensure concerns of minorities in the city were also heard. Tseng also focused on the importance of the multi-culture aspect and talked about making Melbourne the capital of the aboriginals. Tseng also explained why he thinks Melbourne is poised to be a world city by 2030.

Tseng’s deputy Lord Mayor candidate Gricol Yang is a Commercial Banker and works for ANZ Banking Group.

Currently, Sally Capp is the Lord Mayor of Melbourne, the Victorian capital. Capp was elected as an interim Lord Mayor in mid-2018 after the former Lord Mayor Robert Doyle resigned from his position after sexual assault allegations. Doyle served as the Lord Mayor of Melbourne for almost a decade since 2008.

Belgian formation talks: King consults incumbent PM

Monday, December 3, 2007

The caretaker prime minister of Belgium, Guy Verhofstadt, reappeared on the political stage today as he accepted the royal request to suggest solutions to the ongoing federal government formation talks.

Recollecting his statement to the press on June 10, 2007, when he recognised his electoral loss and the victory of his opponent Yves Leterme, he told reporters today that he “hadn’t thought nor hoped to face you once more, but the King has asked me to inform him on a short term about possible strategies to deal with the political stalemate in which we have ended up over the last few months.”

Our country is experiencing one of its most severe political crises of the last decades. The elections are six months behind us you see, and the country still doesn’t have a worthy government. Meanwhile, our country’s image is being damaged en socio-economic and daily problems of the people remain unsolved.

Indeed, after 177 days, the country’s political parties have still found no compromise on the roles of the French- and Dutch-language community. Two days ago, Leterme returned to King Albert II to tender his resignation as leader of the formation talks.

The incumbent PM said he would discretely contact the leaders of all democratic parties during the next few days. He said his starting point would be dual: the country needs a considerable reform of its federal status, and there are certain urgent problems that outrange the capacities of the caretaker government dealing with the ongoing affairs.

Verhofstadt called for all involved to take responsibility, in the interest of the country and its citizens.

Best Weight Loss Foods: 50 Delicious Foods That Help You Lose Weight

By Janine Michaels

When people go on a diet, they often think that they’ll have to deprive themselves of anything tasty or good for the sake of losing some pounds. While it’s true that you’ll need to deny yourself those fatty food items that you’re used to eating all the time, it’s also true that you can still find plenty of foods for weight loss to keep your dieting experience full of flavor and variety.

The best diets are ones that don’t force you to eat bland food every single day, and, pretend that you’re actually going to like it. I’m sure you’ve been on some of these strict plans that made you feel cranky and ready to toss out every piece of lettuce onto the cold, hard floor. I mean, yes, you need to eat healthy, but there’s got to be some enjoyment too.

Many people give up on their diet after two or three weeks because they just can’t take the loss of enjoyment any longer. We eat to live, but we also eat to savor and enjoy our food. Take away the joy, and there’s not really much incentive to eat another plate of greens with light dressing.

Some of the most popular diet plans available today feature cheat days – days in which you can eat whatever you like. While you don’t want to go hog wild on cheat days, you can enjoy these days with abandon, if you stock up on healthy food items. When your cupboards are filled with fatty foods, then guess what? You’ll eat them without thinking. If you stock up on tasty, but low calorie foods, you’ll still be able to stick with your weight loss goals without feeling guilty.

Here’s a list of low fat food items that can make your low calorie meals more enjoyable:

Gregory Kurtzer discusses plans for Rocky Linux with Wikinews as Red Hat announces moving focus away from CentOS

Friday, December 18, 2020

Last week, on December 8, US-based software company Red Hat announced plans to shift their focus away from CentOS in favour of CentOS stream.

Started in 2004, CentOS has been a free-of-cost free/libre open source software which provided binary-code compatibility with Red Hat Enterprise Linux (RHEL) — Red Hat’s GNU General Public Licensed paid operating system. Gregory Kurtzer told Wikinews he started CAOS Linux around the time when Red Hat announced End of Life for their Red Hat Linux in favour of subscription-based Red Hat Enterprise Linux. CAOS was succeeded by CentOS when Rocky McGaugh, a developer of CAOS rebuilt the source code of RHEL to provide a monetarily free alternative. CentOS was absorbed into Red Hat in 2014, with Red Hat gaining the trademark rights of “CentOS”.

Red Hat also sponsors the development of the Fedora operating system. Until now, software development took place on Fedora, which was later adopted in RHEL, which the Red Hat maintained and provided support for, for those customers who had RHEL subscription. CentOS would then follow RHEL’s release cycle to provide the same features free of cost, but without the support.

Stream was announced in September 2019, just two months after Red Hat was acquired by IBM. CentOS Stream’s development cycle had new features added to it before the features became a part of RHEL. Stream receives more frequent updates, however, it does not follow RHEL’s release cycle.

With CentOS Stream, developments from the community and the Red Hat employees would take place beforehand on both Fedora, and Stream as a rolling release, before those features are absorbed into RHEL. CentOS followed the release cycle of RHEL and therefore it was a stable distribution. Features available in CentOS were tried and tested by Fedora, and then RHEL maintainers.

Red Hat’s Chief Technical Officer Chris Wright wrote in the announcement “CentOS Stream isn’t a replacement for CentOS Linux; rather, it’s a natural, inevitable next step intended to fulfill the project’s goal of furthering enterprise Linux innovation.” Since the announcement was made, many people expressed their anger on Internet Relay Chat (IRC), Reddit and CentOS project’s mailing list. CentOS 8’s End of Life (EOL) has been moved up from May 2029 to December 31, 2021, while CentOS 7 is expected to receive maintenance updates through June 2024, outliving CentOS 8.

Soon after Red Hat’s announcement, Kurtzer announced his intentions to develop Rocky Linux, to fill the role CentOS had been playing for so long. Kurtzer said Rocky Linux was named after Rocky McGaugh. “Thinking back to early CentOS days… My cofounder was Rocky McGaugh. He is no longer with us, so as a H/T [hat tip] to him, who never got to see the success that CentOS came to be, I introduce to you…Rocky Linux”, Kurtzer wrote. Wikinews discussed with Kurtzer the beginning of CentOS, and future of Rocky Linux.

While no formal date of release has been announced for Rocky Linux, Kurtzer said they are planning to release the CentOS replacement before the end of life of CentOS 8. Kurtzer also said Rocky Linux will run on both x86-64 and ARM-based processors, and CentOS users would be able to convert their OS to Rocky Linux just by running a single command.

Saying Rocky Linux is for the community, Kurtzer said he “take[s] the responsibility of ensuring that all decisions are in favor of the community and the project and free from corporate control” including his own company. Talking about the attention from the userbase Rocky Linux has received, Kurtzer said, “I have never seen an open community come together this fast and be this passionate about working together towards a common goal.”
