正确吃大包的方法

很多人，包括我在内，一直以来都在错误地吃大包。我们从小就观察别人在餐馆里吃大包，也听家人告诉我们如何吃。人们喜欢吃大包，但最后总是会弄得满手油腻。最近，我了解到正确的方法与一个锡矿城有关。这种方法是受到当时一个锡矿公司的经理的启发。在锡矿开采过程中，锡具有较高的密度，会沉在土壤下方。TT5机器需要先去除土壤上的杂质，然后才能开采到锡矿。同样的概念也适用于吃大包。所有美味的食材都在较大的底部。将大包翻转过来有助于酱汁流回顶部。现在只需将顶部的纸底移除，然后用勺子或筷子开始享用，让食客迅速获得所有的肉和内陷。酱汁在底部与浓郁的面包完美搭配！下次你有机会吃大包时，试试这种专业的吃法吧！

The Importance of Proper Window Glazing: Lessons from a Viral Video

 Introduction:

In the age of social media, videos have the power to captivate audiences and create widespread awareness about important issues. Recently, a video showing a worker applying butyl sealant onto a large gap between a wall and a glass roof has gone viral. The video highlights a crucial mistake made by the worker, as they failed to use a backer rod to provide support to the sealant. This oversight led to the sealant sinking and shrinking within just three months, resulting in peeling paint and water leakage. Let's delve into the consequences of improper window glazing and the significance of proper roof flashing.

The Impact of Improper Window Glazing:

The viral video serves as a wake-up call, shedding light on the repercussions of inadequate window glazing. When the sealant is applied without a backer rod, there is insufficient support for the sealant, causing it to sink and shrink over time. As a result, the integrity of the seal is compromised, leading to water seepage during rainfall. This not only damages the aesthetics of the structure but also poses a risk of structural damage if left unresolved.

Creating Awareness about Window Glazing:

Fortunately, this viral video has played a vital role in raising awareness about the importance of proper window glazing. It emphasizes the significance of using appropriate techniques and materials to ensure a durable and watertight seal. Professionals in the field of construction and architecture have been vocal about the necessity of employing a Z-profile roof flash or L-flashing with premium silicone to achieve effective and long-lasting results.

The Role of Masking Tape:

Another notable aspect depicted in the video is the absence of masking tape during the sealing process. The lack of masking tape can result in messy sealant lines, further detracting from the visual appeal of the window. Professionals emphasize the importance of using masking tape to achieve clean and precise sealant lines, enhancing both the aesthetics and functionality of the glazing.

Addressing the Consequences:

When individuals fall victim to faulty window glazing practices, it is crucial to understand their options for recourse. Typically, the responsibility lies with the contractor who carried out the initial work. The affected individuals should reach out to the contractor and highlight the issue, demanding proper rectification. However, it is unfortunate that in some cases, contractors may resort to temporary fixes that last for a limited period before leakage occurs again. In such situations, seeking legal advice and involving law regulators might be necessary to ensure a satisfactory resolution.

Conclusion:

The viral video showcasing the improper application of butyl sealant has sparked a much-needed conversation about the significance of proper window glazing techniques. It serves as a reminder that attention to detail and adherence to industry best practices are essential when it comes to maintaining watertight and durable window seals. By promoting awareness and urging law regulators to enforce standards, we can strive towards creating an environment where contractors prioritize quality and ensure long-lasting solutions for individuals seeking their services.

Turbine ventilator works without electricity

Work from home is not a myth anymore after the two years of movement control order, MCO has been lifted. Hybrid working model is proven to be possible! What do i learn from WFH (Work from home) in that two years? 

First of all, I have figured a way to enhanced the WiFi signal at home without buying new a router. Telephone line that no longer been used can be converted into LAN line. No more weak WiFi signal around the home now. 

Next thing will be sound quality is crucial! Apparently, condenser microphone is directional! The side with the logo is the most sensitive area that should be speak into. Sound mixer is typically useful for online meeting purpose or getting background music playing while telling a story online. 

The electricity bill has been skyrocketed during the MCO. It was really warm without Air-conditioner turned-on while WFH. The solution to that for me will be turbine ventilator that i found after MCO. Designed to fit through a glass-roof. Took a month to research and spoke to the contractor who could get it done. A 25 tonne crane was involved in the process of making it happened. An fully Aluminium turbine ventilator 16 inch in diameter that was claimed that will last almost forever. The light weight turbine made using Aluminium helps make the bearing last longer. Warm air is now constantly being exhausted from the ventilator. Strongly recommended for counties that are located around the equator. Countries with four seasons might need a shutter window to prevent warm air from leaving during winter! 

 Hot air rises, while cold air sink works in modern houses too! 

Youtube Short recorded for the process of getting the turbine ventilator over the roof.

Save electricity while work from home

 Electricity usage at home for sure has increased by far a lot for many people in the past whole year. It has caught my attention recently when my exhaust fan blower sounds louder than it used to be. The blower has never been serviced since when it was first installed ages ago. No one told me i need to do so. It was a good sign than it reminds me of the types of blower fan available in my house. I first Google and look for guide on how to service the blower. No much guide available for the exactly same model to mine. 

It leaves me no choice but to explore it all by myself. Servicing the blower fan blade seems to be an easy task that not many people talked about or at least in my cycle of friends. The whole process took less than half an hour. 

The same goes with the exhaust fan in my bathroom. Never thought that it will be so dirty. The same goes with the air-conditioner indoor unit ! There are mould growth all over the interior surface. Clean with soap and then disinfect using hand sanitizer with at least 60% alcohol content. 

All blowers now blowing at maximum speed at pin drop silent. The wind is so strong now!

It certainly helps save electricity for long period of operation. Dusty gathered for sure increase the payload of the electricity motor. Less weight for sure will need less electrical energy to provide a spinning motion to the blower. Help this sharing helps you too. 

Using mid-point concept solving a quadratic equation.

 In this method, it make use of the sum of root and product of root to find the x value when the y is zero. 

Quadratic equations has a symmetry at mid-point between the roots. 

The difference before and after the middle point has to be the same!

A standard equation of x^2 - (R1+R2)x + (R1)(R2)= 0  has to be used to obtain the root by the end.

Then the sum of root = R1+ R2 = -b/a

Also, the product of root = (R1)(R2) = c/a 

Following ax^2 + bx + c = 0, getting the root by solving the unknown by first getting the midpoint. 

Hope this help simplify.

Education Revolution - Remote Learning

Asynchronous learning platform will be helpful especially during this difficult time. A link explain the different different synchronous and asynchronous learning. We need to adapt this remote learning policy despite it was thought to be a sprint initially that end up to be a marathon.

Hope my viewer will get ready for alternative assessment. Gauging learning outcome is part of the learning journey. I bet no one knows what is the best practise at the moment until we all work together in getting the best approach for alternative assessment to written examination that we all get used to.

Hope my compilation of videos on physics and maths subjects helps!
