Common prejudices about VPN

Leave a comment

We living in such time when we want to use the Internet without restrictions, freely and safely, right? So it’s high time to discover the VPN services. In the recent times, government representatives have been furiously and actively picking on this thing. They were calling it an instrument of terrorism. Because of those biases, there is a need to dispel numerous of encountered stereotypes.

The Virtual Private Network is named in such way because it guarantees private life. Numerous celebs, who are on the public eyes, tend to use it because it made their personal information, messages and photos inaccessible for reporters, fans and followers. In addition, VPN hides not only individual and true location, but also protects the information that is sent to you and by you. By the way, if a particular website is closed for your location, you could easily outmaneuver the Internet with the help of VPN services.

There is a stereotype that if you are ordinary personality, there is no need to use VPN service. I am sorry to inform you that you are deeply mistaken about this issue. The problem is that average people need such services as VPN even more than any other. The era of Internet censorship is developing and the list of the blocked websites is only growing. Many residents of your native country may be set aside of foreign online stores and services. On the other hand, you still need to get some information from closed websites.

The most appropriate outcome for this controversial situation is VPN services. There are numerous of them on the Internet, so it seems to be a tricky process of choosing the best one. If you are in two minds, you could check VPN service on Anta.net. The thing is that Anta.net is considered to be one of the most trustworthy websites for this aim. There you have a golden opportunity to compare reviews and prices.

The price policy of paid and free websites should be discussed. There are many biases regarding the phenomenon that free websites are by far better that paid one. The problem is that for quality and comfort, without a doubt you should pay. As a matter of fact, the services that do not obtain money from their users, could use or sell your personal information. So, there is no point to pay for actually nothing. Do not pursue something free of charge. It is a general truth that free cheese is only in a mousetrap. In contrast, paid VPNs are not interested in selling data, as they value their users and reputation.

All in all, VPN allows you to achieve an acceptable level of security with minimal costs, using already existing resources of World Wide Web. Thanks to this, VPN as a service is very cheap and do not make you splash out.

Most dangerous viruses under the spotlight

Nanotechnologies changed our life and its duration once and for all. Using them, we have possibility to prevent, cure and accelerate rehabilitation of by far many illnesses. Until recent years, for example, children were prone to certain infectious diseases, for which there was no effective cure. Vaccines have almost eradicated some of these conditions. Another bright example is regarding surgical intervention. If you needed a major operation, you would be confined to bed for weeks. Nowadays many operations use less invasive procedures, requiring day surgery only. In addition, the survival rate for many cancers has improved considerably over the recent decades, due to development of chemotherapy to treat the condition.

The problem is that there is no need to suffer from sickness if you could get ahead of it. Prevention tools like nanoscopes definitely could help you to do it. Manchester University’s scientists discover the most powerful nanoscope few years ago. It was called microsphere nanoscope due to the fact that it manages to produce an image using tiny optically transparent quartz glasses. Then, optical microscope from microlens could easily improve an image and define the smallest part of it. Could you imagine that for your eyes the objects in size of nearly fifty nanometers is visible? In contrast to last decades where microscopes could only display some small objects, nanoscopes have done unbelievable breakthroughs. The opportunity to take a look inside the cell and observe outer boundaries of the objects is nowhere near. In fact, the nanoscope with such resolution permits to study the actions of live viruses that guarantee to improve understanding of their nature and let researches come up with brilliant ideas and develop different methods to deal with them effectively.

Living cell is not the limit for upscale equipment such as nanoscope of LIG Tech that makes it possible to watch objects that are even smaller than living objects without destroying them in process. This perspective promises completely up-to-date discoveries in the various fields of science. That’s why nanotechnologies should not be underestimates, but even vice versa, actively used in all spheres of social life. Today cancer is the most horrible and hardly curable disease. However, nanoscience could not only detect, but also treat it at the molecular level. Imagine that with the help of hand-held tools you could pass check-up not leaving your home. It is pretty reasonable because for many patients trip to hospital seems to be stressful and exhausting and there is likelihood that visiting hospital, in most cases, deteriorates the state of patient health.

All in all, the progress in medical sphere is considerably slow. However, over the last years, the scientists have made some worthy breakthroughs that help in faster detecting, well-timed prevention and improvement of life in general. In few years, we are all hope that medical improvements will change the cause of history dramatically and all of us must forget about maladies in perpetuity.

The latest generation hydraulic lime furnaces design in focus

Leave a comment

lime-pointing-stroudNearly a decade or two ago hydraulic lime was delivered to the construction site unprepared – without subjecting to roasting. It was quenched similarly to the as the common lime and put directly into the dough, kneading bad crumbling pieces of beetles, runners, and so on. With this process the fine grain burnout largely remained intact, capable of ruining your late solution subsequently quenching.

That’s why the French method of processing lime is gaining momentum, implying division lime material into several fractions, depending on the speed and completeness of quenching the latter, though it arrives at the shelves of specialty stores in the form of powder. The prominent construction and architectural organisations, like Telling Company, widely applying hydraulic lime and lime mortar solutions, makes a choice in favour of this method, so let’s have a closer look at it.

The furnaces hydraulic lime are essentially identical to the common uses for the firing of lime. In France for quite a long time short flame furnaces with egg-shaped shafts (9 meters in height and maximum width of 3.5 m and 1.6 m diameter furnace top) have been used, arranged next to one another in the general stone casing. At the bottom of the shaft of peculiar form of the grate in the form of a conical cage of iron bars is set in the midst of which ordinary horizontal grille and prominent inland mines to a height of 1.75 m installed. Such a device is intended to increase the contact of surface with the air burned with material located in the lower part of the shaft, and thus accelerate its cooling. Side sections for unloading are not implemented, as all mine raised above the ground so that the trolley can fit under the grate and take material. Furnace top tight-fitting lid, suspended on a chain to the rocker with a counterweight, to slip the gases from the furnace wall of the latter, beneath the furnace throat, there are openings to the horizontal elections, common to a number of furnaces and conductive gases to the sucking fan.

The downsides of high temperature plasma disposal

Leave a comment

For the temperatures at which the waste can be converted into a plasma (over 6,000°C), implementing the reactor design is a complicated task, at least the situation is not likely to change in the foreseeable future. Thus, the conditions of reliable operation of the reactor temperature process using a plasma heating should be in the range of from 900 to 1,200°C. This temperature level is well maintained in many other well-known and already mature technologies, which are based on pyrolysis and gasification processes. However, as the years of operating experience pass, all of these technologies hasn’t achieved the traditional burning of solid waste in terms of the technical and economic indicators.

Environmental benefits of plants with plasma technology compared with incineration, including addressing the problem of dioxin, are actual for the large productions. First of all it should be noted that almost all modern MSW incinerators are provided with the regulated emissions of harmful substances in flue gases, which if necessary may be significantly optimised.

Reduced levels of dioxins to standard values is performed in two stages using methods and scrubbing process. This also applies to installations using plasma torches. Despite the high temperature (above 1,200 – 1,300 ° C, and in some cases up to 1,600°C) at which reportedly (according to supporters plasma method) another dioxins synthesis generally does not occur at all sites with plasma torches and mounted equipment for the removal of dioxins. In the comparative tables, powered by analytical materials, it is mostly often indicated that the quantity of dioxin emissions is lower than those provided for by Directive 2000/76/EC of the European Parliament and the Council of Waste Incineration, meaning the presence of dioxins in the flue gases is yet attaching. Therefore, we can say that the burning of the resulting synthesis gas dioxins occur and additional cleaning of flue gases for normal values is required.

As for the decision of the general scrubbing of the synthesis gas produced by gasification of MSW using plasma heating, it is a relatively new issue, and thus its cleaning circuit is rather complicated. Thus, for example, the technology of Simdean, an expert in plasma waste disposal and industrial waste disposal solutions manufacturing, syngas passes successively through scrubber, a spray tower, wet electrostatic filter with activated carbon and fed to desulphurisation, and selective catalytic reduction of nitrogen oxides. Further, in some technologies quenching gas is used, which essence lies in the fact that the hot synthesis gas exits the reactor at about 1200°C, and then cooled in a water tube heat exchanger to about 200°C. It should be noted that in this case, there are serious doubts concerning the application of normally used in such cases tubular heat exchanger. Moreover, the operation in general of any heat exchanger at the dust-laden gas with a temperature of 1,200°C is questionable. The synthesis gas contains fusible particles that can intoxicated the heat exchange surface completely.

Changing The Game. EU Legislation Adjustments That Speed Up UK Economic Growth

Leave a comment

To eliminate the legal barriers in intellectual property legal framework, and thus speed up the emergence and application innovations and growth of GDP, the branch of the University of Manchester, UMIP, focused on intellectual property management has proposed a several possible solutions, narrowed to EU legislation adjustment.

Changing the rules of the European Union takes a long time. Prior to that, some of the limitations of the exclusive rights may be introduced at the level of the UK.

A permit for full text search in databases (text mining), and in respect of protected works, with the non-commercial research (the concept of «Fair Dealing», established by Directive 2001/29/ EU is not applicable here; restrictions should also apply to commercial research, but this is the level of the European Union).

Allowing free copying (private copying) for personal purposes. EU legislation allows such copying but subjects to payment of compensation, and such compensation is now included in the cost of the devices, making copies, and it appears that the levying of such compensation to the consumer unreasonably so far as to copying is a part of normal use of plenty of devices (e.g., in the case of recording devices acquired online movies and music), and there is no evidence that such copying causing any harm to holders.

Allow a free format conversion (format shifting) of lawfully acquired content (for example, when recording music from a CD to your hard drive for further listening on multiple devices). Now in the UK you need to notify customers that changing the format entails a breach of copyright. It seems clear that rights holders have long known about these user actions (as well as a copy for personal use), so the amount of remuneration for the use of works, apparently, have already been established with regard to such actions that mean a loss of rights holders to conduct it unwise; therefore, users should be able to convert and burn the content on a variety of devices for themselves and their families freely.

Free study of all kinds of works in any media for the purpose of non-commercial research should also be ensured.

Free archive libraries any works, including orphan and protected (including audio-visual materials and audio), as well as the digitisation of such works (like a digital archive has enormous economic, social and cultural value);

The freedom to establish parodies and pastiches (in modern mass communications network parody plays an important role, allowing many people to show their creativity and attitude to particular events) should be also enabled.

In practice, situations occur where the limitations of the exclusive rights is provided by law, directly or indirectly canceled the terms of agreements concluded with the users of the rights holders. In this regard, the legislation should clearly state that its provisions can not be modified by contract.

The complex of measures should give a positive impact on both development of industries and human interaction with intellectual property products.

The link building insights – making it through to the top

Leave a comment

Taking into account the words of Google powers that be, link building can easily be referred to grey hat methods. Of course, we don’t mean natural links that largely make SERP functioning predictably (or to the extent that we’ve got used to). So where is the edge? How to balance between SERP acceptable techniques and cost-efficiency? HTP Digital, a prosperous digital marketing agency Manchester that helps stay its customers competitive in extremely tough niches, shares a bunch of tactics you may want to take advantage of.

Backlinks still matter…

If links were gone, it would lead to chaos. However, optimisers have become wary of promoting links, while rookies oftentimes do not even know how to do kick off a link building campaign, fearing the bad link can receive sanctions and damage the reputation. After creating the site and before spinning links, you must understand how links affect your domain authority, plus you should understand the diversity of links type.

For example, some backlinks can stay under the control of the website owner. Some backlinks are spread through forums and blogs, and if the optimiser creates anchors for them, the risk of getting the sanction naturally grows (artificially set anchors may also increase suspicion). Some SEOs leave a link in the signature in the guest posts, although this method ceased to be an effective way to increase the weight of the resource. Once promising, now it poses the risk of spam classification.

Link building: what Google is sick of

Backlinks distributed in the network virtually unchecked, can also lead to sanctions. Such links can be placed in the biographical material in the history,about and similar info sections. Stuffing footer with unnatural links is something that Google is particularly rageful about. Not only these links have long attracted the attention of the search engine, Google even warned against placing such reference elements.

For long time publishing ‘dofollow’ links in the forum and website profiles was considered to be a juicy method. Optimisers went even further and automated the process with the custom software; some of the popular apps are available for sale. However, Google is constantly changing and the method is not only no longer relevant, but dangerous for your website health. HTP digital marketing manchester has been studying the topic and found out that in 84% of cases such method gave no effect, while in 17% of which a penalty was issued.

To conclude, shall we abandon the links? There are SEOs who panic and refuse to take advantage of the method, which is certainly a doubtful decision. Yes, search engines may react negatively to link building. But it doesn’t necessarily indicates that the method is bad – it’s a matter of right approaches. Google focuses on the users, and you should do so also. In order to get quality backlinks and natural, it is necessary to distribute content: the more organic the process is, the more Google likes your domain. After all, it all goes to the state of affairs where white hat methods play the decisive role.

Understanding The Power Of Ultrasound Cleaning

Leave a comment

Ultrasonic cleaning efficiency depends on the parameters of the sound field (vibration frequency and sound intensity) as well as physico-chemical properties of the liquid detergent. Selecting the sound field parameters and the washing liquid properly can grant the required cleaning efficiency. Much depends on the quality of the equipment itself: if you are looking for high quality ultrasonic cleaner offering decent functionality, drop in at hilsonic.co.uk – a reliable UK manufacturer, boasting an impressive line-up of powerful ultrasonic cleaners at affordable prices.

In the cleaning process the surface tension of the washing liquid also matters, degrading wetting process parts to be cleaned and preventing the penetration of the detergent solution into the gaps. To reduce the surface tension of the washing liquid additives surfactants are used which improve the wettability and the surface, creating a subtle adsorption layers on the particle surface contamination and promoting their detachment easier.

Introduction of ultrasonic vibrations is carried out through the plates, which have a good acoustic contact with the transducer. The geometrical dimensions of the plates are determined on the basis of the conditions for obtaining the required intensity of the ultrasonic vibrations, while the optimum value is selected depending on the nature and type of contamination of parts.

Decontamination, degreasing and cleaning in the focus

The main types of contaminants that are removed in the process of ultrasonic cleaning can be grouped into four categories:

  1. Solid and liquid films – different oils, greases, pastes, etc.;
  2. Solid precipitation – metal and abrasive particles, dust, deposits, water-insoluble inorganic compound (scum, flux), and soluble or partially soluble organic compound (salt, sugar, starch, protein, etc.);
  3. Сorrosion products – rust, scale, etc.
  4. Preservatives, preservative and protective coatings – enamels, resins, etc.

Wind Energy: Noise Aspect Overview

Leave a comment

According to Global Wind Energy Council estimates the world wind power development will contribute to a reduction of annual CO2 emissions by 1.5 billion tons by the year of 2050.

Wind power plants produce two kinds of noise:

  • mechanical noise – noise of mechanical and electrical components (for modern wind turbines this aspect is virtually negligible, though it is significant as for older models of wind turbines)
  • aerodynamic noise – the noise from the interaction of wind flow with the unit (amplified by the wind pressure on the blades)

Currently, in determining the level of noise from wind turbines use only the calculation method. The method of direct measurements of the noise level does not provide information about wind turbine noise, since the effective separation of wind turbine noise from wind noise at the moment is not possible.

Noise sources comparison

  • The pain threshold of human hearing – 120db
  • The noise of a jet engine turbine at a distance of 250 m – 105db
  • The noise from a jackhammer to 7m – 95db
  • The noise from the truck at a speed of 48 km/h at a distance of 100 m – 65db
  • Background noise in the office – 60db
  • The noise from the passenger car at a speed of 64 km/h – 55db
  • Noise from a wind turbine at a 350 meters distance – 35-45db
  • Background noise during the night in the village – 20-40db

In the vicinity of the wind turbine at the axis of the propeller the noise is sufficiently increasing and wind turbines may exceed 100 dB. An example of such a wind turbine design miscalculations was Grovian Turbine. Due to the high noise level setting it worked for about 100 hours and was dismantled.

The laws passed in the UK, Germany, the Netherlands and Denmark, limit the noise level of operating wind power plant up to 45 dB in the daytime and 35 dB at night. The minimum distance from the installation to residential buildings is 300m. In addition, the business owners are forced to initiate regular check-ups to ensure proper functioning. Typically, the 3rd party companies are involved in the activity; in the UK, perhaps, the largest provider is Granada Material Handling, the company offering wind turbine services as well as wind turbine inspections at moderate pricing to keep operational expenses at an acceptable level.

Horizontal Wells & Their Profiles

Leave a comment

In aspiration to educate its customers, European Geophysical Services has launched a narrow-targeted media campaign aimed at increasing the level of understanding of borehole drilling processes. Being an expert in geophysics, UK-based company has already implemented over 150 borehole drilling projects, which is eventually one of the main company’s specializations.

The basics of horizontal wells

Horizontal well type implies having a stem portion angled to 90° vertically, although other wells drilled at a sharper angle may also fall under this definition. Depending on the horizontal trajectory of the wellbore and drilling technology adopted, horizontal wells are arbitrarily divided into four groups.

Wells with a large radius of curvature of the set are drilled using conventional equipment for directional wells. They are characterized by a set tempo curvature of 1-2˚/10 m and horizontal trunks length of 1500m and more. These wells can be deep enough and have a trunk diameter of up to 444.49 mm.

Horizontal wells are drilled with an average radius of curvature of special downhole motors with bent sub and stabilizers. The pace for the curvature of these wells is set at 3 – 7710 m, the radius of curvature equals 45-300m, while the of diameter horizontal borehole is 311.2 mm.

Horizontal wells are drilled in small radius of curvature with special drilling systems of two types. In mechanical rotary systems composite curving drilling direction with an inner drive shaft to the bit is used. Horizontal wells of small radius of curvature are characterized by a set rate of curvature of 30-100° to 10 m; 90° tilt is gained within 6-12 m range. Horizontal wells of this type are limited by the diameter of the wells drilled by 114,3-165,1 mm diameter bit; the usual length of horizontal section is 180-300 m.

Ultrashort horizontal wells are designed for the development of heavy oil and tar sands technology sidetracking. The technology is based on the use of jetting a downhole drilling head lifting system placed in the reservoir against the expanded area of the vertical well. With such a system of vertical shaft can be quickly spudded several radial horizontal holes with a diameter of 100 mm and a length of 30-60 m. Continue reading “Horizontal Wells & Their Profiles” »
