Choosing the VPN provider to satisfy your needs

You must be already more than aware of the most important benefits that virtual private networks bring to the Internet users: privacy, anonymity, extra security – all this is especially vital when connecting via public Wi-Fi. The number of solutions offered today is unbelievably huge. Worth mentioning, the price is far from the only differentiating factor, since there are many VPN features to consider. What you can do to ensure a successful deal and convenient usage in the perspective is study the offers made by VPN service providers listed on AntaNET or any other VPN reviews.  Indeed, why pay for something you do not actually need?

Prior to comparative analysis of the available VPN services, do assess your VPN needs:

  • If you are going to securely access the home network only, there is no need to pay to a VPN provider, since a remote VPN is initially designed to provide a secure access to a remote network. Instead, a VPN server should be running on a home router. For that, you can get a router that supports DD-WRT or the one with a VPN server pre-installed (e.g. Netgear Nighthawk and Nighthawk X6).
  • Next, think of secure casual browsing. As long as you tend to be a frequent public Wi-Fi user with high-bandwidth needs, you should study the paid offers made by VPN providers.
  • In case you have a reason to appear as if you use the online source from another country in order to access some specific content exposed to geographical restrictions, you definitely need a VPN service possessing servers in that particular region.
  • Prioritize anonymity and plausible deniability. If the total anonymity is what you need first of all, then a serious VPN may not be enough – empower it with TOR.

As soon as the VPN needs are defined, it is time to compare the offers made by several providers relying on a set of criteria to check:

  1. Protocols supported

If you look into any comparative review of the modern VPN protocols applied by VPN services like the one published on AntaNET, you are most likely to find OpenVPN to be the leader in terms of security levels and so-called ‘processing costs’. The only case when OpenVPN is soundly rejected in favor of another protocol is the VPN use on mobile devices: for now, Android and iOS only support L2TP/IPsec natively, but not OpenVPN.

Remember that PPTP is currently the most vulnerable protocol, applying weak encryption methods and threatening with unstable connections. This can only be acceptable in the case of casual web browsing in a coffee shop.

  1. Number and location of servers in use

Most VPN providers manage hundreds of servers all over the world today, which is not surprising given the fast development and promotion of VPNs. It is good when the VPN provider possesses stable servers in rather diverse locations.

Do pay attention to the countries though. You won’t benefit from using the VPN with servers in Africa, for example, in case you aim to access US media sources applying geo-blocking. What’s more, mind the country where the VPN provider’s company is located: make sure it is not a close ally of your own state, if you want to avoid the government pursuit in case of some unforeseen circumstances.

  1. Number of concurrent connections allowed

A common VPN service must guarantee at least 2 concurrent connections, added by the opportunity to link your router to the VPN.

Of course, the more available connections, the better: ideally, you will want to build a security system for all of your personal and household traffic, which requires connecting multiple devices to the VPN.

  1. All possible limits and restrictions (there are always some)

This may be surprising, but some VPNs do restrict a number of protocols or services you might wish to access. In this connection, it is recommended to check the list of blocked services beforehand.

Furthermore, make sure not to get throttled by your VPN like you used to by the ISP – what is the point of connecting to the VPN then?

In addition, try to avoid VPNs with bandwidth restrictions, unless they are reasonably high.

  1. Logging issue

Perfectly, the VPN provider will not keep any logs. However, it is a very rare case, so do ask about the log’s content and retention period.

  1. Presence of a kill switch system

The feature is a precious one in situations when the VPN connection drops for some unknown reasons: the tool will simply lock the connection automatically and thus break traffic exchange with the open internet, which may start by default.

  1. Payment methods

These are worth considering when you wish to stay totally anonymous or avoid any kind of government pursuit – then anonymous payment methods are what you need. A number of VPN providers accept cryptocurrency and even gift cards from large retailers like Walmart or Target as a VPN credit.

Advantages of different types of nanotechnologies for treating the illnesses

Awareness of the need to use modern medicine achievements of nanotechnology is growing over the last few decades. Taken into consideration the social importance of medicine sphere, society has a great expectation regarding overcoming illnesses of past, present and future, as well as harmful effects of environment and bad habits.

As for one eminent tool of the nanotechnologies is optical nano scope. Nanoscope is unique tool with its amazing capabilities. They allow achieving a sufficient increase of definition in order to see individual molecules and atoms. It is possible to examine objects without destroying them. This fact is vital in terms of medical and biological using. Observing some viruses, bacteria and so long help to study, in some cases, living objects. Some types of optical nano scopes also let manipulate individual molecules and atoms and there is such equipment like advanced optical nanoscope of LIG Technologies in UK and it is widely approved.

optical nanoscopes

The next prominent device of nanotechnologies is micro and nano devices. Today plenty of nano devices are placed inside the body perhaps for diagnostic and therapeutic purposes. In most cases, they are aimed to investigate the gastrointestinal tract. Due to this purpose, it has really tiny size, approximately several millimeters and it carries a miniature video camera and light system.  Nanocamera could take the photo in that way and it will be transmitted to outside. This method helps to detect correct diagnosis and as a result prescribe appropriate therapy.

By far many of sicknesses are caused by toxins in our bloodstream. Scientists have developed also so-called “nano sponges” that absorb and remove them out. Nano sponges are defined as polymer nanoparticles covered with blood membrane. The red cell membrane could move and attract toxins in the bloodstream. There are many of other both traditional and alternative methods how to lead toxins out of the human bodies. Although they are considered to be not so effective and scientific-proved.

Not only nanotechnologies could stop disease inward, but also decelerate the aging process.

In addition, there is one crucial problem that was discussed a long time ago that humanity faced with really powerful viruses that demands stronger antibiotics. From the 1987, science and medicine did not produce truly new types of antibiotics. The problem is that injections are going on to become more common and casing real problems. Nevertheless, scientists have made a discovery that, in their opinion, will bring dramatic changes. It is a new type of antibiotics, which included 25 antimicrobial agents, the most important one called teixobactin. This antibiotic kills bacteria by blocking their ability to produce new cells. In other words, the microbes cannot grow and develop resistance to the drug under the influence of this remedy. Teixobactin are considered to be trial and tested and believed to be highly effective in the fight against Staphylococcus and several other bacteria that causes tuberculosis.

At first, laboratory tests on teixobactin were carried out on mice. The vast majority of experiments have shown the efficacy of the drug. Human trials are going to begin in 2017.

In a nutshell, nano technologies are definitely help us to improve our quality of life and assist to solve numerous of problems regarding healthcare concept.

The application of ultrasound on industrial scale: cases and directions

One of the most promising technologies in industrial ultrasound use is the connection of polymeric materials: welding by the means of ultrasound. Ultrasound allows you to take advantage of several application methods: welding fittings of hard plastic at a great distance from the place of entry of ultrasound (200-250 mm); welding multilayer structures made of reinforced plastics and soft tissues of artificial materials; welding polymers characterised by complicated welding and/or welded poorly by other welding methods; embedding precision metal parts in plastic; welding polymers on contaminated surfaces, without obligatory pre-cleaning and degreasing.

The main advantage of ultrasonic metal welding is the narrow focus of heat exposure and high repeatability of results, which is especially important for large-scale manufacturing processes and mass production in general. In addition, sonication precludes significant thermal and light radiation during welding with no melted metal mass production in the process. Ultrasound allows to weld similar and dissimilar metals of different thicknesses. The technology is most commonly used in the electronics industry.

Firmware holes and dimensional processing of brittle materials

The technology allows for firmware holes and recesses of various shapes and sizes in the articles of stone, glass, porcelain, ceramics, ferrite and other brittle materials using abrasive powder and tools, vibrating at an ultrasonic frequency.

Processing bottomhole zone wells

The effect of exposure to ultrasound at bottomhole zone is as follows: salt deposits on the walls of pores are broken, thereby increasing the permeability of the formation; acoustic degasification takes place and gas slugs in the capillaries are destroyed while electrostatic layer lowers the surface tension of the liquid in capillaries and reduces viscosity. The set of equipment consists of ultrasonic generator and the radiator shell of special design, placed on a vehicle with bay geophysical logging cable up to 4 miles.

Applications of ultrasound

Here’s the breakdown of industries utilising ultrasonic cleaning equipment according to Hilsonic, a large-scale UK-based manufacturer focused producing ultrasonic cleaner equipment.

  1. Processing industries: mineral processing, enrichment and hydrometallurgical processes metal ores, etc.
  2. Oil and gas industry: oil recovery wells, extraction of viscous oil separation processes in the sand – heavy oil, increasing the fluidity of the heavy oil, etc.
  3. Metallurgy and mechanical engineering: refinement of metal melts, structure refinement ingot / casting, metal surface treatment for its hardening and stress relief, treatment of external and internal surfaces of the cavities of machine parts, etc.
  4. Chemical and biochemical techniques: extraction, adsorption, filtration, drying, emulsification, obtaining suspension, mixing, dispersing, dissolving, flotation, degassing, evaporation, coagulation, coalescence polymerisation and depolymerisation processes, the preparation of nanomaterials, etc.
  5. Energy: combustion of liquid and solid fuel cooking fuel emulsions, the production of biofuels, etc.
  6. Agriculture, food and light industry: the processes of seed germination and plant growth, the preparation of food additives, confectionery technology, the preparation of alcoholic and soft drinks, etc.
  7. Utilities: water recovery wells, potable water, removal of sediment from the inner walls of the heat exchangers, etc.
  8. Environmental protection: waste water, contaminated by petroleum products, heavy metals, persistent organic compounds, purification of contaminated soil, cleaning of industrial gas streams, etc.
  9. Recycling: devulcanisation of rubber, purification of metallurgical slag from oil pollution, etc.

The commandments for reaching your target audience effectively through ads

When choosing Internet marketing tools, advertisers should take into account the specifics of the modern audience. According to recent reports 62% of visitors visit various website while they are at work. So marketing during ‘working time’ can not simply use the traditional methods of video and print advertising. And the traffic is not constant in its entirety. Attendance peaks fall on Monday and Thursday, while the decline falls on Friday. So how can you convey information effectively while your target audience is at work and extremely limited time frames to capture their attention? Here’s what Htpdigital.com, a prominent digital marketing Manchester enterprise with a savvy B2B digital marketing agency department on board, experts say about the techniques for reaching the audience experts say.

Google has admitted that the greatest number of searches is now falling into news category. Previously, entertainment-focused yellow pages were more popular. Now people want to read news on the Internet, and they usually focus on the local news. Territorial separation of the audience is another fact that should be considered. Advertising on news portals has its own characteristics. The audience is serious and tends to take well-structured and concise texts. The main function of advertising is not to attract attention, but to spread the word.

Moreover, the information supplied in the advertisement, must comply with the advertised product. Conventional techniques exaggerating and extolling the qualities of the product are not likely to be totally effective. Content surrounding the news article, must conform to the structure. The ‘ideal’ ad unit must contain the minimum of information, but attract attention at the same time. Short titles, attractive visual characteristics, laser-guided keywords… the tools are many. The basis of modern online advertising account for contextual blocks that appear on resources of relevant topic. This increases the efficiency of advertising by meeting the needs of users and selective approach to the audience. Google and Facebook-caliber services offer advertising based on the query words, geotargeting, tags and more. High efficiency is provided by a content filtering and the audience, but for the fact that the advertisement is displayed only by those potentially interested in the ad block.

While on search pages text blocks are the most appropriate tools, on the news pages the text is lost until it is not at least supplied with a picture. Naturally, modern advertising is all about interactiveness. In this case, using banners is a reasonable way to go. Where banners are very difficult to place in full compliance with the theme of the site and the necessary information, a teaser could be a panacea.

The teaser contains a picture and text (usually non-informative) – a short, ‘teasing’ phrase, or even provocation, but it has to match what you are promoting. Experts say that the greatest harm to the advertising product is brought by ‘deceptive advertising’ when users are interested in teasers, go to the target pages and find nothing in common with what was said in the teaser.
