QRA's role in eliminating denger fever in Singapore

The Temperature Cyle proposed by QRA to Stress Screen the Polyethelyne Containers through numerous rounds of Heat and Cold Stressing to induce failure in the container. 

   Last year, QRA was approached by a huge MNC whose Social Enterprise arm was tasked to find ways and means to eradicate the dengue fever menace caused by Aedes mosquitoes in Singapore. Now Singapore is a tropical country, and our climate is very humid. We can record, easily 100 - 120 days of rain per year, so there are instances of water ponding and places where these mosquitoes can breed. 

Aedes is one such specie of mosquito and dengue fever can be deadly. Every year, scores of people, will get infected, and some may die from this disease which is characterised by intermittent high fever, chills, some rashes on the body and the person infected must be hospitalised immediately. 

The chamber providing the Temperature Cycling Test - ETSP Temperature Cycle Chamber (S.Korea) 

The MNC's social enterprise arm partnered with our National Environment Agency (NEA) for this project called Project Wolbachia. You see Wolbachia mosquitoes are another specie of mosquitoes, which are harmless and do not posess nor carry the dangerous dengue strain in their bodies.  Hence the objective of Project Wolbachia is to breed enough Wolbachia in the Labs at the MNC and later release them into the open air and allow them to a) fly around and b) breed with the Aedes mosquitoes.

The offspring of this new specie, will then be rendered harmless and behave like any mosquito The offspring is hopefully not able to transmit any dengue fever virus. When the Wolbachia mosquitos are bred in the Labs, they are then kept in refrigerated glass tanks at - 17 C. 

Multiple Level Polyethelene Containers - each level housing mosquitoes.

After enough of them are bred and raised, they will then be shepherded into containers such as the above. Each container contains 30 segments and each segment housing some 100 mosquitos (my guess). The execution of the project is high tech, like in some James Bond movie. These containers which are made of Polyethelene, will be mounted in refrigerated vans and these vans will ply a certain route through all the housing estates in Singapore.

At certain junctions or roads, the GPS will trigger the opening on the side of these vans automatically and one segment of the red container (there are 30 segments in total housed in a clear plastic cover) will be released and the Wolbachia mosquitoes will fly out and do their thing. 

The concern for the MNC was this :

The van is refrigerated and the mosquitoes are kept in the freezer at -17 C. Once they reach the designated location for release, the sliding door will automatically open and 35 - 38 C air will rush in. 

Hence after repeated drive bys, the containers will be experiencing a Temperatue Cycle of roughly 

- 17 C to + 35 C in a few minutes.

Over repeated locations, this will have an expansion (heat at 35C) and contraction (cold at -17C).

The concern that repeated Temperature Cycles will lead to a breakage of these containers which can be disastrous.

Hence, after discussing with QRA's experienced engineers, we devised a Temperature Cycle as shown below for them below : 

                                     Stress Screening Test Cycle suggested by QRA 

       Going Above and Beyond the Operational Temperature experienced by the  

                                                                  Containers. 

We suggested a Stress Screen Test, of roughly 200 cycles. Each cycle is 5 hours long, and the 200 cycles is expected to run for 1000 hours (or 200 multiplied by 5 hours) or 41.67 days. (42 days) 

The reason for the lower cold zone temperature and the higher hot zone temperature is the basis for the stress screen. Always subject the test samples to worse zones of temperature than they will be subjected to - in the end, only robustly designed samples will make it. 

Subject the test samples (containers) to extremes of temperatures, so that in test failures (cracks) are observed IN THE FACTORY and these weaknesses (material or otherwise) can be rectified before sending out the samples into the field.

The Stress Screen Test was carried out late last year and our MNC customer was very satisfied with the result.

All 3 containers passed the Stress Screen Test of 1000 hours. No cracks, delaminations or anything broken.

QRA has the distinction of making Singapore a safer place to live, work and play.

Shenyang Ku Gong Palace Visit - 3rd July '26

A recent visit to Shengyang China, unveiled a pleasant surprise. Our hosts, Hyperbaric Manufacturer Canta Medical Systems brought us to visit the Chong De (the last Manchu emperor) palace called Ku Gong. China was ruled by the Manchu (Qing dynasty) for almost 3 centuries before the formation of the Chinese Republic in early 1900s (1912 I believe). The first President of China was San Yet Sen. The last emperor was Pu Yi.  

Shengyang was the old capital city before it was moved to Beijing. 

There is the much larger palace in Beijing called the Forbidden City. The buildings there are very similar to the Cu Gong in Shenyang except much larger. 

It is a sprawling place, with easily 3 million square feet in area. There were many courtyands, as well as the sleeping quarters for the emperor and his officials.

With our principal host and guide Karen. 

The signs of technology and culture is apparent for all to see, and when we were there, our gorup of 15 were the only foreign tourists visiting. The vast majority were Chinese national or local tourists.

Many were dressed in the old imperial clothes of the emperor (yellow) or the empress or princesses.

One needs to be relatively fit to climb up and down the stairs to visit the palace and their buildings. 

Sheng Ji Soya Sauce Chicken - Best Tasting in the World

 

Located at the corner of Geylang Bahru Hawker Center, is this stall called Sheng Ji Soya Sauce Chicken. Run by 2 sisters in their 70s, the stall offers chicken rice, braised chicked Stewed feet (for collagen) and chicken noodles.

Last Saturday, after my run at ECP, I tried it out, just for fun. I had ventured and used the basic social science principle. If there is a queue of people waiting to order the food, it MUST be of a certain standard.

I was not disappointed. The soya sauce chicken was the best I have had in years. I am not even a soya sauce chicken rice fan, but one bite and I was in gastronomic heaven.

The meat was tender and the skin, was oh so flavourful. The rice was nice and not clumpy.

The 'jiao zhi' or dumplings were robust and had the nice water chestnut inside to give it the crunchy feel. Some other folk who were in front of me ordered like half a chicken with 2 big bags of noodles (yellow mee kia and white kway teow)

I ordered the S$ 8 (with more ingredients or jia liao) and it was an extremely satisfying lunch and so cost effective.

I plan to buy this meal for my family very soon.

QRA'S athletic chambers for worldwide sports clients

                           Athletic chamber for up to 4 athletes at Sport Singapore

Presenting QRA's athletic chamber with control of the following parameters listed below :

a) Temperature

b) Humidity

c) Sunlight

d) CO2 removal

e) Altitude

f) Rain

QRA is only one of four worldwide manufacturers or system integrators of athletic chambers for enhancement of elite sportsmen. There are numerous studies showing that the Live HIgh Train Low and High program has its benefits on sports performance. (LHTLTH). 

The basic concept of altitude training is such :

> At sea level (or 20.9% O2), the average person consumes O2 and his VO2 max helps convert the oxygen together with the ATP (produced from mitochondria in our red blood cells) into energy to produce work.

> Within each cubic centimeter of blood, there is (for example) 10 buckets of haemoglobin which carry the O2 to the various parts and these are functioning well. So if there are 10 buckets and O2 at 20.9% is considered as 1 unit, then the work done is 10. Or 10 x 1.

> At higher levels, where the air is thinner (at base camp Mt Everest at 5000 m), the O2 is something like 16.5 % or 2/3rd the O2 level at sea level. Logically speaking the person who has 10 buckets of haemoglobin will then function at 10 x 0.67 or 6.67. Hence every step he takes is only at 2/3rd the energy since O2 is crucial for the work to be done by the human body.

> With controlled environment, where the athlete (or person) is sleeping at 16.5 % for up to 2 weeks, he will amazingly produce (if that is the right word) more haemoglobin buckets to compensate for the low 02. So with adequate sleep and activity at the higher altitude (we call it acclimatization), our bodies will eventually create up to 15 buckets of haemoglobin, so as to produce 10 output. 15 x 0.7 is 10 at higher altitude. 

> The sleep rooms at high altitude (Sports Singapore has the facility) produce these environments for sleep and daily activity, so after roughly 2 weeks, the athletes would have 15 buckets of haemoglobin.

> Now if they were to train or run races  at 20.9%, their output work done will now be 15 x 10 or 15 which is 50 % more than what they were previously. 

> This means a tremendous improvement in performance, sportsmen will actually run faster, and produce a lot more energy especially at races or high level games like football, basketball tennis, the list is endless.

> Imagine running 30% faster than your opponent who once was as fast as you !

> You would be able to reach the ball quicker, your reaction time would be faster and you would score many more goals than any other ordinary player. Its a dream ?

Why dream ?

The reality is here.

John, Mum and Papa (1987) 

This blog will hit 1,000,000 views in the next day or two. I wish to dedicate this milestone to my beloved parents, Geoffrey, Anna as well as to my younger brother John. 

Though my parents are not here in this world anymore, I believe somewhere they would be happy  sharing with me on the quiet satisfaction on reaching this milestone.  When I started this blog way back in 2008, I just wanted to keep a journal of my life journey and wrote whatever came to my mind then. 

                    May many blessings be upon you wherever you go. 

            Surely goodness and mercy be upon you and yours for the rest of your days.

Dialect films. Let more of them be screened in Singapore.

I refer to the brouhaha about the latest film, Dear You, in Chaosan dialect, where literally  thousands of Singaporeans have gone to Johor Bahru to watch.

I profess I am not a dialect speaker, although my heritage is Cantonese, hence the pull of the grandmotherland and motherland is watered down and the ethnic attraction of going back to China or India respectively is practically 0 in my consciousness.

I am proud to be half Chinese. I acknowledge my mother and grandmother were Chinese citizens, but I am a patriotic Singaporean and will remain so. I am very happy to witness China's progress in the last 30 years or so, developing from a poor country till today, a highly industrializing and ultramodern powerhouse, at least from what I observe during my visits to tier 1 and tier 2 cities.  

The issue is about the wanting to connect with the 'lao jia' or hometown for the people who were born there. Many years ago, from the early 20th century to late 20th century, many Chinese people fled China to come to S.E. Asia to look for a more prosperous life, hence, the men left their womenfolk back in the villages and sent back qiaopi or monthly remittances to feed the family who were probably living a hand to mouth existence.  When China started the road towards market capitalism in the mid 1990s, it steadily uplifted hundreds possibly 1 billion people in the last 25 to 30 years from dire poverty to middle class wealth and standards of living.  

Life is short, and it is a shame that the authorities and censorship board still retains archaic regulations which are not applicable in modern day Singapore. I do not think that there will be people - after watching the movie - will want to pack up and migrate to Suzhou province. 

When the speak Mandarin program was kickstarted. This was targetted at Chinese Singaporeans more than 60 years ago, to foster Mandarin as the mother tongue, this program and policy was the right one. Chinese of all dialects speak 'Pu Tong Hua' in China and this unifies the peoples North and South.

Let there be many more screenings of Dear You in Singapore. Many families, want to just spend quality time with grandma and grandpa and organize a family outing, so why make it so trying that there are so few screenings here ? 

There are foreign films aplenty in Singapore, so why limit the number of screenings if the demand is greater than supply ? 

Do something meaningful for the people, our  Government leaders. 

Everything can be amended if it poses no threat
