New browser with VPN function from Opera

The Norway Opera Company has provided the new development which will suit for certain the PC users for whom safety is extremely important. An innovation is the built-in free VPN service. This function allows not only keeping safety by coding the data, but also allows to visit Internet resources which are forbidden at the territory of our country

What is VPN service?

Why don’t the websites know of user’s location while using VPN? The regular browser establishes a connection between the websites, showing where there is now the owner of PC. When using VPN the special service contacts websites therefore the present location of the person remains unknown. Instead of your location the websites obtain data on where there is any Opera service which is scattered worldwide: USA, Netherlands, Canada, Singapore and Germany.

Developers of the advanced browser claim that they have solved two main difficulties of users in using the private virtual network, namely:

  • The user doesn’t need to deal with connection option because everything occurs automatically independently;
  • The network is absolutely free, and doesn’t require monthly prolongation.

Statistically in autumn of last year, only 4% of all PC users used the Opera browser, but the innovation, most likely, will return to this browser its former popularity.

However if you don’t want to install the Opera browser, and don’t trust free VPN at all, but still have a need for this service, then it is possible to offer a paid subscription. The best VPN services can be found on AntaNET website – there you able to find the main information about them and the cost of a paid subscription.

In the case of enhancement of browser the developers were guided by a thought of the personal data at Internet protection. It is especially urgent for those companies which success depends on the security of their information. Also data security is important for people who often make money transfers by the Internet during remote working. Of course, VPN will be irreplaceable for those who like to be connected to public Wi-Fi outdoors too. Safety in this case is guaranteed by complete privacy and this is excluded for third parties access to personal data of the user.

For whom will the built-in VPN service be most useful?

The new browser is urgent for those people who need to bypass blocking for access to forbidden websites. At this stage only 10% of people regularly use means in order to bypass blocking. In addition to VPN the various plugins, “Turbo” mode and anonymizers can be added to such means. Many of them are presented as a built-in function in browsers, but requiring separate start. But they have another bypass technique. For example, the “Turbo” mode allows bypassing of blocking only if the website doesn’t use HTTPS enciphering. When using all these means it will be possible to hide the visit of the user from website administration, but not from the provider. The provider can understand by traffic was the website with blocking visited by a user or not. At the present moment the bypass of blocking isn’t regulated by the law in any way, not stopped and not pursued, but it isn’t excluded that it is possible in near future. Using of VPN “deceives” both websites and provider as the visit of blocked resources isn’t represented anywhere.

What do we have in come-off?

Summing up the results, one can be said – the updated Opera browser thanks to the built-in VPN technology has such advantages:

  • Bypassing of blocked Internet resources which won’t be noticed by provider;
  • Safe using of Wi-Fi in public places;
  • Free and automatic using of VPN.

Making The Most Of The Ultrasonic Cleaning

Ultrasound boasts a multifactorial effect, so its application can significantly accelerate any of the cleaning methods and improve the quality of final results. Alternating pressure fluctuations of fluid particles and acoustic phenomena, the ‘sonic wind’, cavitation and ultrasonic capillary effect offer unparalleled efficiency.

The nature of the effect

The primary energy role is played by cavitation. During the collapse of the cavitation bubbles microstreams are formed and cumulative fluid velocity reaches a hundred meters per second, towards the surface to be cleaned. Under the influence of shock waves and high-speed microstreams an intensive film degradation of impurities (solid or liquid types) and its separation from the surface takes place. Cavitation provides intensive ultrasound emulsification of liquid and ultrasonic dispersion of separated solid contaminats.

Due to acoustic streaming is provided by removal of the boundary layer solution or destroyed under the influence of cavitation in the volume of fluid contamination. A particularly important role is played by acoustic streaming in removing soluble contaminants.

Cleaning efficiency increases when the surface to be treated to the emitter is reduced. However, placing the product to the emitter in less than 1-2 mm is impractical because at small gaps between the transmitter and the surface conditions remove contaminants from the boundary layer and decreases the activity of cavitation due to changes in the collapse scheme of cavitation bubbles.

The benefits

The advantage of ultrasonic cleaning is not only an ability to achieve high-quality cleaning test surface from a wide variety of contaminants, but also to remove impurities from the capillary cavity defect. The most effective use of ultrasound is the mode that provides an emergence of ultrasonic capillary effect. The mode contributes to reagent capillaries filling to a greater depth and a greater rate. In addition, significantly accelerates the diffusion of dissolved gas to the mouth of the defect; dissolution of contaminants presents in the cavity of the defect; the diffusion of impurities to its mouth. As a result, accelerates the process of filling voids and defects in general and increases the depth of penetration of the working fluid in the blind capillary channels. The mode is supported in neoteric equipment, such as Hilsonic – a seasoned UK-based business, focusing its effort on studying ultrasound and producing an impressive line-up of ultrasonic cleaner devices.

The use of ultrasound for cleaning can significantly improve quality control. Thus discontinuities are cleaned to a sufficient depth not only in case of liquids, but also such contaminants sparingly as polishing paste. As a result, the number of identified traces close to the total number of defects is taken into account. The use as a detergent liquid water and aqueous solutions of glycerol and a dispersing agent for cleaning in an ultrasonic field is more effective than the use of solvents such as acetone or benzene. This is due to greater activity of acoustic cavitation in water and aqueous solutions than in acetone and petrol. The use of ultrasound allows solving the problem of replacing explosive, environmental hazards to more environment-friendly materials.
