Ergonomic office chairs are one of the most popular accessories in modern offices. Many office workers spend over eight hours a day, sitting in their office chairs. An ergonomic chair can reduce the load on the back, shoulders and neck of an office worker.
Ergonomic chairs are more expensive than conventional office chairs, but the extra costs will be rapidly recovered by increased productivity of the workers and the prevention of various occupational injuries.Well chosen office furniture increases productivity of the employees to a great extent. An ergonomic office chair will set your employees free, and they will be able to focus more on their work without being distracted by pain in the back, neck or legs. Remember, you as an employer will be liable to cover the medical costs (and ongoing healthcare costs) if an employee develops a health condition in the workplace.You need to consider a lot of things before you can buy the right ergonomic chair.
It should be adjustable for any type of body. Make sure all the features are working properly. Individually approaching the choice of an ergonomic office chair is important because different people have different body types.A person sitting on an ergonomic chair should have his soles flat on the floor rather than hanging in the air.
This is a very important guiding principle for those who are out to buy an ergonomic office chair.Instead of a straight back chair, the back should be curved. This provides thorough support to the waist. Armrests, which support the shoulders, should also be there.An office chair with the right ergonomic capabilities reduces fatigue and keeps the employees in a good mood.
A well furnished and ergonomically set up office keeps the workers motivated, ensures a healthy and light atmosphere and eventually increases productivity. Recently, there have appeared many new ergonomic chairs. Some of them may even seem inconvenient at first.
Even so, in the end, people who are experiencing discomfort or pains in their back will usually improve after starting to work in an ergonomic chair, instead of a regular office chair. A convenient, comfortable ergonomic office chair, protects employees from the risk of injury, and is capable of raising the spirits in the office.Today, ergonomic office chairs are of practical use and stylish too. The best ergonomic office chairs come with a number of features such as ability to tilt, armrests and adjustability of the seat.
Such chairs are designed with ergonomics as the main guiding principle and also international health and safety standards. If you want to offer your employees a comfortable and risk free work environment, you must go for ergonomic office chairs.Garrett knows a lot about ergonomic office chairs com/ergonomic-office-chair-one-of-the-most-popular-modern-office-accessories/] and mesh office chairs Source: Source: com/2899097. RELATED QUESTION If Apple is really building an electric car, what does this mean for Tesla?
Is Apple's product quality likely to be dramatically superior, and is there room in the market for both Tesla and Apple? There is more than enough room for Apple and Tesla for two main reasons.Market SizeElon Musk - "Given that annual new vehicle production is approaching 100 million per year and the global fleet is approximately 2 billion cars, it is impossible for Tesla to build electric cars fast enough to address the carbon crisis". To put this into perspective, Tesla is aiming to deliver 90,000 cars in 2016.
Elon has also made a prediction that Tesla will sell 500,000 cars by 2020. Even if that's correct, that's only 0.5% of global production.A valid counterpoint is that annual production will decrease as people start to use shared autonomous car services instead. But even if you consider a massive drop of car sales (50%?
), Tesla still wouldn't even be close to having a monopoly. Specialized carsI believe that 10-20 years from now many people won't buy a car and instead exclusively use services like Uber (with autonomous cars). When that happens, car manufacturers will be incentivized to build many differenttypesof cars, each built around a different experience.
For example, there will be:Sleeping cars. These will be designed with beds and focus on sleeping (i.e. very comfortable, noise canceling, dark shades, etc.)Business trip cars.
These will be spacious and designed to let you work (ergonomic office chairs, computer screens, super fast wifi, etc. )All of these specialized cars need to be manufactured. So even though fewer cars will be made in aggregate, moredifferentcars will be made.
This expands the market and makes room for new manufacturers to compete. Is Tesla Creator Crazy Like a Fox Giving Away Patents?
WhiteWater World features several water slide attractions (all built by ProSlide), a large wave pool and separate children and toddler areas. There are food and beverage outlets, retail stores, a surf school, a function area and numerous shaded areas with seating. The park features three water slide towers, each featuring a collection of slides grouped by the level of thrill. The park also features three family-oriented water attractions separate from the towers. All of the park's attractions have an Australian beach culture theme.
The slide tower near the entrance contains the park's main thrill slides. The Wedgie is a body slide featuring a trap-door release into a near-vertical 17-metre (56 ft) drop. Riders then enter a fast, downward-spiralling turn and reach speeds of nearly 45 kilometres per hour (28 mph) before they are slowed in a run-out chute. The ride was the first ProSlide SuperLOOP in the world. The Green Room consists of four people boarding a cloverleaf-shaped tube in which they traverse a 66-metre (217 ft) long tunnel followed by a 17-metre (56 ft) drop into a funnel. Within the funnel, riders oscillate back and forth up the walls at the side and drop into a splash pool. From its opening to 2015, The Green Room has been Australia's largest ProSlide Tornado beating Wet'n'Wild Water World's Tornado in height and tunnel length. On the Super Tubes Hydrocoaster, three people sit on a 45-kilogram (99 lb) raft, whose weight is mainly attributable to a large magnet on its underside. Riders experience several steep drops followed by magnet-powered inclines, ending with a splashdown in a small pool. The Super Tubes Hydrocoaster was the second ProSlide Hydro Magnetic Rocket Slide in the world and continues to be Australia's only water coaster.
The second slide tower, along the park's southern border, features two rides with more moderate thrill ratings. On The Rip, riders hop into a four-person, cloverleaf-shaped tube. They descend a dark tunnel before entering a large, open bowl. The raft circles the centre of the bowl then exits down through the centre and into a splashdown pool. The Rip is the first and currently the only ProSlide Behemoth Bowl in Australia. The BRO (Blue Ringed Octopus) is a water slide consisting of eight 120-metre (390 ft) long lanes. From a height of 16 metres (52 ft), riders mount a personal mat and slide head first down an enclosed spiral tunnel before merging into open, parallel lanes to the finish. In 24 seconds, riders can reach speeds of up to 50 kilometres per hour (31 mph). The BRO has a capacity of 1000 riders per hour. When The BRO opened in 2006, it was the largest ProSlide Octopus Racer in the world and is the only one in Australia. A third slide, Triple Vortex, was added to the tower in late 2014. Pairs of riders will slide down an enclosed tube slide with three funnels, similar to miniature versions of the park's Green Room funnel.
The slide tower in the southeast corner of the park contains five slides designed for those who desire a mild thrill. Some of the slides on this tower interact with Dreamworld's Cyclone roller coaster. The Little Rippers are two ProSlide duelling cannon bowl slides. The slides can accommodate guests riding in either one or two person tubes. Riders begin in one of two parallel chutes before entering tunnels and splitting off in opposite directions. Each tunnel has a steep drop into the bowl element of the ride, after which the raft drops down through the centre and into a run-out chute. The other three slides on this tower are collectively known as The Temple of Huey. Guests can ride in a single or double tube. All three slides are ProSlide Pipelines. The three slides are individually named Broken Headz, Cut Snake and Screamin Right Handers and are 99, 104 and 88 metres (325, 341 and 289 feet) long respectively. Broken Headz and Cut Snake are enclosed and Screamin Right Handers is an open flume.
Three family-oriented attractions are located on the ground level, detached from the three slide towers. Two of these are children's areas and the third is a wave pool. Pipeline Plunge is a children's area with four flume slides and hundreds of water activities. The area, originally called Nickelodeon's Pipeline Plunge, is a large, multi-level water play structure featuring an 1,000-litre (220 imp gal; 260 US gal) tipping bucket which dumps water on guests every few minutes. It played host to two "Slime Fest" events in 2009 that included several live shows, a dunking chair and "Australia's biggest sliming" where 1,000 litres (220 imp gal; 260 US gal) of slime was dumped on park guests using green coloured water in the giant tipping bucket twice daily. The mass sliming returned in the 2010/2011 summer holidays as part of the Summer Funomenon. Pipeline Plunge is a WhiteWater West Aqua Play area. Wiggle Bay is a Wiggles themed toddler area featuring musical and interactive water play activities, a shallow pool and four Wiggles-coloured water slides, located at the back of the area. these were manufactured by ProSlide. The interactive features are manufactured by WaterPlay. The Cave of Waves is a themed 2,685-square-metre (28,900 sq ft) wave pool which can generate waves of up to 1.5 metres (4.9 ft) high. Built by Murphy's Waves of Scotland, the pool has a constant temperature of 26 degrees Celsius. The Get Wet Surf School makes use of the pool for its lessons outside of normal park operating hours.

The operation of the motor can be understood by referring to figure which shows one pole of the motor with a shading coil. Considering a cycle of alternating current (fig 1) applied to the stator winding we will explain the working of shaded pole motor.During the portion OADuring the portion OA of the alternating-current cycle [Fig 1], the flux begins to increase and an e.
is induced in the shading coil.
The resulting current in the shading coil will be in such a direction (Lenzu2019s law) so as to oppose the change in flux. Thus the flux in the shaded portion of the pole is weakened while that in the unshaded portion is strengthened as shown in figure 2.During the portion ABDuring the portion AB of the alternating-current cycle, the flux has reached almost maximum value and is not changing.
Consequently, the flux distribution across the pole is uniform [See Fig 3] since no current is flowing in the shading coil.During the portion BCAs the flux decreases (portion BC of the alternating current cycle), current is induced in the shading coil so as to oppose the decrease in current. Thus the flux in the shaded portion of the pole is strengthened while that in the unshaded portion is weakened as shown in Fig 4.
The effect of the shading coil is to cause the field flux to shift across the pole face from the unshaded to the shaded portion. This shifting flux is like a rotating weak field moving in the direction from unshaded portion to the shaded portion of the pole.The rotor is of the squirrel-cage type and is under the influence of this moving field.
Consequently, a small starting torque is developed. As soon as this torque starts to revolve the rotor, additional torque is produced by single-phase induction-motor action. The motor accelerates to a speed slightly below the synchronous speed and runs as a single-phase induction motor.

What's the Difference Between Asynchronous and Synchronous Motors?Jan 4, 2013Leland Teschler | Machine DesignThe increasing importance of energy efficiency has brought electric motor makers to promote a variety of schemes that improve motor performance. Unfortunately the terminology associated with motor technologies can be confusing, partly because multiple terms can sometimes be used interchangeably to refer to the same basic motor configuration. Among the classic examples of this phenomenon is that of induction motors and asynchronous motors.
All induction motors are asynchronous motors. The asynchronous nature of induction-motor operation comes from the slip between the rotational speed of the stator field and somewhat slower speed of the rotor. A more-specific explanation of how this slip arises gets into details of the motor internals.

It doesn't...The axes are pressure ratio and airflow. Lines of constant blower speed are drawn on it.Airflow can decrease, if you increase rotational speed and pressure ratio, but airflow decreases if you increase the pressure ratio anyways, it's a matter of how much in each variable.The way to use it is look at the speed you expect the blower to be running at, and calculate what the pressure ratio would be with the downstream restriction for any given mass airflow.
This will be a quadratic function, ish, and where it intersects the curve of constant rotational speed is the airflow/pressure ratio combination you can expect to see in that system, at that speed.Based on a centrifugal blower manufacturer's graph, how come the airflow of a fan reduces as the rotational speed increases?Based on a centrifugal blower manufacturer's graph, how come the airflow of a fan reduces as the rotational speed increases ?
It is called an airlock, just like on a submarine or a spaceship. They generally have a separate small heater or AC duct. The idea is that untempered air from the outdoors is trapped in this small "room", then heated or cooled before it gets into the main building space.
Obviously in a busy building that has constant coming and going where both doors are open at the same time, this doesn't work so well. But in general it is a very practical method of minimizing the amount of unconditioned air that enters a building.What is the tiny room between two rows of automatic doors at store entrances called?.
