Top benefits of using robotic vacuums (Part 2)

For economical and practical cleansing power, a robotic home appliance is turning into an easy alternative.

Implausibly Economical

Today’s robot vacuum cleaners give multiple tasks. They not solely clean; they remember your house’ layout, and are ready to dump the dirt they collect. They also realize their way back to their charging station.

Some higher-end models have advanced sensors and are ready to transition between cleaning floors and carpeted areas while not manually changing settings — alternatively, they permit you to regulate them through a smartphone app.

The organized, back-and-forth, or circular motion of the machines conjointly ensures that each of the floors of your house is free from dust. It interprets a lot about their thorough cleaning ability overall.

Saves You Time

Everyone’s lives became progressively busier within the twenty-first century. Indeed, multitasking has become predominant to, and a part of,  your contemporary existence. One in all the foremost fascinating advantages of robot vacuum cleaners is that you don’t have to be compelled to be physically present once the vacuum is working.

Flip it on before leaving the house, and it’ll do all the work for you, whereas you’re out of the house. Therefore, time not spent manually vacuuming will be spent relaxing, wiggling with your children, or doing no matter what your heart needs. Indeed, according to the adage, time is money. It applies to this product also.

Works on Completely Different Surfaces

Another good thing about the robotic home appliance is that it works on multiple varieties of surfaces, from carpets to wooden floors to concrete.

As mentioned, higher-end models are ready to transition between different types of surfaces throughout the same cleansing cycle. With these alternative models, you merely amend the setting, place the unit at a chosen start line, and set the applied timer as usual.

Top benefits of using robotic vacuums (Part 1)

Robotic vacuums have genuinely taken off over the last few years. It is straightforward to understand the reasons. With their practical, hands-free action and ease of use, homeowners have discovered various advantages of buying this type of cleaner. Still, are they worthy of a higher price? In this post, we have put together some prominent perks you can expect to get from using one.

Robot Vacuum Cleaners: What Are They?

They are an autonomous appliance designed for cleaning tiles, hard floors, and carpets of any dust and dirt, much similar to other kinds of vacuums. Their significant difference is that the robot can diminish the work amount that you need to do.

Since their release, they initially struggled with their homeowners. That said, after innovation, they have become more popular than ever.

Undeniably, in recent years, they have drawn endless interest. It is partly because they have been more affordable, yet mostly since they tend to be more efficient at completing the intended purpose – detailing your floors while not asking you to do much work.

Are you looking to purchase a vacuum? Then, you may do yourself a disservice without accounting for a cleaning robot. To help you decide whether it is a suitable device for your needs and wants, let’s have a closer look at their main benefits.

Easy To Use

Maybe the number one advantage of bringing home a robot vacuum is that it is usually simple to use. As soon as you programmed the machine for given spaces and set the timer for a start time, the robot will virtually run on its own. Put it on the floor in a proper starting spot and call it done.

Further, many units can self-regulate. You will not have to worry about its malfunctioning or getting stuck on a surface.

The strange uses of vacuum cleaners

In addition to removing dirt on the floor as well as carpeting, the vacuum cleaner also has many uses that users don’t think of.

Clean pet hair

The main job of the vacuum cleaner is to suck all the pet hair that sticks to the carpet and on the floor. However, users are less likely to use vacuum cleaners to clean pets’ fur in the place where they live. Too much fur in a washing machine is one of the culprits that cause leaks and damage to the water pump system. Users should use a vacuum cleaner to vacuum carpets, blankets and sheets before putting them into the washing machine.

Insecticides

A Ohio State University study found that regular vacuuming would kill 96% of fleas (adults and larvae) indoors. Vacuum cleaners are also an effective way to remove dust mites and human skin cells they eat from mattresses.

Vacuum cleaners and vacuum cleaner accessories are a good way to catch spiders or mosquitoes in corners. After killing all insects, users paste a clean white cloth on the tip of the vacuum cleaner to remove spider web.

Refreshing upholstery, pillows and carpets

In addition to removing dirt, a vacuum cleaner and a baking soda box can remove odors and brighten the fabric. Simply, sprinkle baking soda on chairs, pillows, carpets and damp sponge to evenen the surface. Let baking soda penetrate the surface for at least an hour and then vacuum, users will see the fabric surface is brighter, the smell has been treated.

Reduce allergy in the house

Keep windowsills and crevices free of allergens by vacuuming regularly. Users should use a dust brush to vacuum the window to remove pollen and dust.
Users can use the dust brush accessory of the vacuum cleaner to remove dust on lampshades, books, lights, blinds and even leaves before cleaning with water. This eliminates the original dust layer, preventing dirt and stains from wiping away after wiping with water.

Cleaning of household appliances

Using a vacuum cleaner to remove dust, plaque from the power cord and refrigerator capacitors on the back will help the machine operate more efficiently and keep the temperature colder. For homes with additional dryers, usually a sauna dryer, a vacuum cleaner can be used to remove excess lint, the leading cause of home fires from the dryer ventilation system. Users should regularly remove the vent on the back of the dryer and use a vacuum to remove excess fibers and dirt.

Why OLED screen phones can cause eyestrain and headache?

Sometimes you experience eye strain, headache, for too long looking at an OLED screen, possibly due to something called Pulse Width Modulation (PWM). This article will help you better understand it.

OLED technology is widely used on smartphones for many advantages, such as dramatic contrast, deep blacks, thinner and lighter LCDs. However, OLED screen phones are using the method of reducing screen brightness as Pulse Width Modulation (PWM).

This is different from LCD screens that use DC dimming, and it makes some users feel uncomfortable. So how are they different? Why is PWM annoying a small group of us and DC dimming is not?

How does PWM work?

This technology simply means changing the width of the light pulses, thereby increasing or decreasing the screen brightness. The frequency of light pulses is often very high – 200Hz and above – making it impossible for the human eye to recognize each individual pulse. Therefore, we will receive the average amount of light that these pulses emit.

The state of the screen turned off or on is actually determined by the amount of light it receives. When you reduce the screen brightness, in fact, the off state lasts longer than it turns on, the amount of light generated by the pulses decreases so we think that the screen is darkened.

At 100% brightness, you notice it’s always bright because the pulse is at its widest. When reduced to 50%, the panel emits shorter pulses, divided into intervals that reduce the amount of light received. And if you continue to lower the brightness, the pulse amplitude will be shorter, the screen stays longer. At extremely low brightness levels, the spacing between the pulses is large enough for them to be discrete and visible to the human eye. At this time, flicker occurs.

Most people are not sensitive enough to recognize this screen flicker. Only a small group felt uncomfortable, although they did not know where the cause was. With this group, flicker for a long time makes the eyes faster tired, headache or migraine. Especially with the habit of using an OLED screen smartphone in low light conditions, or at times when the eyes should rest – for example, before going to sleep – is not as good.

Why don’t commercial planes fly higher into space?

The higher the flight, the more fuel-efficient the aircraft is, the faster and quieter it flies. But they can’t fly into space because of some design limitations.

According to ScienceABC, commercial aircraft usually fly stably at an altitude of 10,700 m above the ground. This is considered the ideal height to help airlines save money, fly faster and safer.

There are three main reasons for this.

The higher the flight, the thinner the air density. This helps reduce the drag of the aircraft. Besides, the air pressed down into the fuselage is also lower than the lifting air.

At the same time, the aircraft must also move faster to gain additional lift of the air. So when traveling at high altitudes, the aircraft will consume less fuel and fly faster.

Because of some design limitations, civil aircraft cannot fly into space.

Another reason is comfort. An aircraft can fly at altitudes of 10,700 – 42,000 m from the ground. Weather phenomena are most influential at altitudes of 0-10,700 m.

If flying at this altitude, the aircraft will not be affected by such turbulence weather. This helps passengers experience a softer and more comfortable flight.

The last reason is for everyone’s safety. In case the aircraft is at an altitude of 11,900 m and something happens to the engine, pilots will have more time to troubleshoot and contact the operating center before an emergency landing.

Most modern aircraft have very good incident response systems. People often think that when the engine is broken, the plane will free fall. But the truth is not so. The plane will hover forward.

Air turbulence due to terrain will not impact the aircraft if it reaches a safe altitude.

With each drop, the aircraft will hover 16-17 m to the front. Thus, from the time of engine failure at an altitude of 10,000 m until landing, the aircraft can go another 160 km.

This allows the pilot to fly the aircraft to the nearest airport for an emergency landing. Thus, flying higher will help the aircraft save, safer and faster.

Besides, flying at an altitude of 10 km above sea level will prevent the aircraft from hitting birds in the sky. Civil aircraft models can reach speeds over 900 km / h. Striking a bird could be equivalent to hitting a flying bullet at 1,220 km / h.

iOS 10 officially launched worldwide

On the morning of September 14, Apple officially launched the iOS 10 version to global users.

Apple’s new iOS 10 update has a capacity of more than 1 GB, this is also the largest iOS update version of the “apple house” in 2016.

iOS 10 was first introduced by Apple at the 2016 WWDC Developers Conference in June, supporting 10 important new features. Highlights include a redesigned lock screen with richer notifications, the ability to interact quickly with apps and expand the 3D Touch option.

In particular, Raise to wake is a new feature capable of waking up the phone lock screen when it is raised, allowing you to have an overview of notifications or updates. The new notification system can work with 3D Touch, allowing you to view and interact with them.

Siri now has better context recognition. It will make intelligent suggestions based on your current location, calendar, contacts, recent contacts, etc.It all relies on Apple’s increasingly mature artificial intelligence system, like what Google has brought to Google Now.

The Photos app is also smarter in detecting and classifying images on the device. The device will group related images together, such as trips, photos last weekend or last year … Then it can automatically revise the film to highlight a specific trip or event.

The key point of iOS 10 is to improve iMessage, the most frequently used app on iOS. It can play videos right in the message stream, triple emoji zoom, and message content can be converted into emoji characters with just one touch. Users can also send videos and attach handwriting to this video.

Devices that can be upgraded to iOS 10 include: iPhone 5 or later, 6th generation iPod Touch, iPad mini 2 or later, iPad 4, iPad Air and iPad Pro models.

Currently, to upgrade to iOS 10 users only need to connect to the internet, go to Settings> General> Software Update.

How was the world’s first solar pathway?

The solar line (including underground light energy collectors) is said to be one of the great innovations in the renewable energy industry in particular and the energy sector in general.

Every technology needs time to test and improve!

Covering an area of ​​up to 2,800m2, Normandy Road is the first solar street in the world, inaugurated in 2016 at Tourouvre-au-Perche, France. But now, after more than 2 years of operation, this road has been evaluated by experts as ineffective.

This road is now degraded heavily, all repairs will be too expensive. Last May, France had to eliminate a length of 100 meters because of a complete failure, could not be used. According to Le Monde, many light-receiving panels were no longer attached to the road, some sections were even broken due to the pressure of the vehicles above.

Besides the aforementioned failures, the Normandy line is also not functioning properly. When inaugurated, the road is expected to generate up to 790 kWh per day, providing enough for 3,000-5,000 people. But when it was put into operation, performance fell by half, continuing to decline over time. This road also creates much more noise than ordinary plastic roads, so that the vehicles passing through here must not exceed the speed of 70km/h!

According to the Daily Caller, this path works inefficiently because it is incapable of tilting in the direction of the sun (like sunflowers), along with being blocked by passing vehicles. Although costing up to 6.1 million USD, roads with up to 75% of the energy panels are broken before installation, which cannot generate electrical energy.

An electrical engineer even said it was “a heavy failure” in an interview with KXLY news. Even when operating normally, each energy plate can only provide one tap and a few bathroom lamps.

Even so, not all solar energy lines fail. In the Netherlands, a similar 70m long road was inaugurated in 2018. The original plan for this road was from 50 to 70 70 kWh/square meter a year, but after 1 year of use, this number up to 74 kWh, the next year increased to 93 kWh.

This year, the Netherlands is expected to open two more roads, one 50m long next to Amsterdam-Schiphol airport and one 100m long from Rotterdam, a few trees, on a bus-only road.

Artificial steak beef: Breakthrough becomes a solution for vegetarians because they do not want to kill?

Now, we can even create solid meat in the laboratory, not just pure meats. Each piece of meat we eat is the muscles of the animal. But animals don’t just have meat.

A cow, for example, has organs and bones – the majority of countries in the world refuse to consume. From the perspective of environmentalists, cattle need food, water, space, energy consumption, and create a large amount of waste – which causes a significant impact on the environment.

More importantly, these are all living animals, and this makes many people choose to become vegetarian because they do not want to kill.

So will it be easier for us to be able to create the right human flesh without leaving waste, nor need to kill any creature? That’s when cell biotechnology comes in, with the potential to create only muscle and fat bundles. They are called “cultured-meat“.

Basic structure of meat

If you look at the piece of meat you still eat under the microscope, you will see that it is a very complex structure – matrix of muscle cells and fat, mixing with blood vessels and connective tissues.

A basic piece of meat has fat, muscle, blood vessels and connective tissue. Muscle cells contain protein, fat is fat. Combined, they create the flavor for each piece of meat you still eat. Meanwhile, blood vessels and connective tissues make it a structure.

A piece of meat needs all four elements, and that is the challenge for biotechnology. Scientists have to make a piece of meat that is full of complexity to be truly valuable, and appear on the market.

Science can create muscle and fat in the laboratory, but blood vessels and connective tissues can only grow in a living organism. So, the meats created so far have only the puree that can be used in burgers, not yet able to get a complete piece of beef.

Ford Explorer is upgraded with a range of luxury amenities (part 1)

Ford Explorer has gradually become the top choice in the luxury 7-seater SUV segment. The current version of Explorer owns many necessary upgrades to maintain the attraction of customers. Those are improvements in interior and exterior to bring more comfortable and luxurious experience.

In terms of exteriors, the new version of Ford Explorer has a new pair of headlights including LED-type near-illuminated lamps as standard equipment. Clamping between the pair of headlamps is a more compact grille than before with more modern meshes. The final highlight on the front of the car is a pair of LED fog lamps with a sleeker and more modern design than the previous C-type lamps.

The body part did not change much from the previous version. The car has a square design and looks great with straight lines throughout the body. This type of design is reminiscent of expensive Range Rover. The most obvious change in the body is the 20-inch wheels that are more luxurious than the old one. Similarly, the tail retains a square design with a bold American feel.

Entering the cabin, Ford applied a scientific, practical but equally luxurious layout to Explorer with decorative details as well as premium leather and wood materials. The space in 3 rows of seats is very wide for all 7 people with a height of 1m65 – 1m7 with full air-conditioning doors for the position on the car. All seating positions are leather-covered, legroom and the ceiling space is reasonably allocated for seven passengers. The top electric seats, inflatable backrests, and even three-level massage capability.

The dashboard area is shaped symmetrically and seamlessly, the modern center console with 8-inch touch screen runs Sync 3. The occupants can activate seat cooling/heating features for the driver’s seat and passenger seat next to them. The standard infotainment system from Ford is almost perfect with high-end Sony audio systems, DVD players, exclusive SYNC®3 systems with voice control capability, plus USB connection/Bluetooth and SD memory card.
