The Latest Technological Advances in Ultrasonic Cleaning

automated-ultrasonic-cleaning-machines-52947-2639615As almost any prosperous industry, ultrasonic cleaning doesn’t stand still – the engineers are grinding away to integrate new methodologies and approaches into practice. Mentioned below is the list of noteworthy technologies that are not yet integrated on industrial level.

Reduced friction between the surfaces

An imposition of ultrasonic vibrations on the mating surfaces to reduce friction arising between them is an effect that can be used in the assembly of main units in which the parts are assembled with an interference, as well as to reduce scuffing and scratching of the surfaces of the mating parts.

A reduction in friction with the help of ultrasound has been successfully demonstrated in industrial trial installations of fuel rods in the fuel assembly skeleton. The trials show that the friction is reduced by 3-4 times.

Also, for example, an application of ultrasonic vibrations to the walls of the crystallizing dish reduces the friction, having a positive effect on the surface quality of the workpiece, reduces wear of the crystallizing dish surfaces (copper or graphite plates and bushings), plus considerable energy savings are achieved due to load reduction on engine.

Free-flowing materials sealing and compressing

Ultrasound promotes densification of free-flowing materials. This property can be used effectively to seal the powders during their compaction. Due to this, the molded product acquires a more uniform structure and its internal defects (cracks and sink) are eliminated, while the level of hardness is increased.

Metal parts hardening

Metal parts hardening by means of ultrasound, where protrude steel balls with a diameter of 0.4 to 2 mm act as reinforcing elements is another reasonable processing method. An ultrasonic transducer transmits pulses to the balls that make them move randomly within a specific hub and strike the surface of the part subjected to hardening with high frequency.

Metals mixing

The method is utilized for aluminum, cadmium, iron, zinc, bronze, graphite and many other alloys production. For example, mixing aluminum with lead improves the processability of the aluminum molding.

The Transport System Of Leeds

A64 LeedsThe greater Leeds is crossed by M1 motorway and a range of highway, including A58, A62, A63, A64, A65. M1 is one of the most important transport arteries of England that connects Leeds with London. A58 leads to Prescott, A62 to Manchester, A63 to Kingston, A64 to Scarborough and A65 to Cumbria. Due to a highly developed road system and a broad variety of hotels in Leeds, the popularity of the city grows among auto tourists exponentially.

In the 60s of the last century an extremely ambitious project of circumferential highway has been implemented in the city. A good part of the road falls to the share of underground tunnels. Thus, in contrast to Birmingham, Leicester and many other cities in England, Leeds has managed to minimize the damage caused to an ancient look and feel by the development of the transport system. Therefore, with a sweeping selection of accommodation options, including totally affordable serviced apartments Leeds offers legions of tourists to plunge into an ancient atmosphere of the city.

Some shopping streets in the central part of Leeds (e.g. Brigat) are closed for vehicles. In early 2006 the free bus route has been launched due to the initiative of city authorities: the form of public transport that exists in many European cities is highly appreciated by the tourists. The trams have been abolished in November 1959; today the city is considering the option of introducing trolleybus routes. The ‘Next generation transport’, held in Leeds in 2009, resulted into a new initiative to reincarnate trolleybus tradition in the city. The city estimates the implementation of a new project at 280 million pounds, while the launch of the new type of public transport is scheduled for the year of 2015. However, a similar initiative has been declined by the government in 2004.

European Gambling Regulation Aspects Nuances

20

The material is prepared by a large gambling reviewing website – Apnet Casino, a platform finding itself on the crest of a wave and investing wisely in research activities.

To date, gambling establishments are allowed in the 128-countries, and Europe is one of the most gambling-saturated regions. Gambling houses present in virtually all the countries of the union with the exceptions of San Marino, Liechtenstein and the Greek part of Cyprus. European laws, which govern the operation of casinos, are relatively liberal. At the same time, the administration of a gambling house is obliged to independently control their customers. The basic attitude of European countries to the gaming business is to ‘resolve and control’. Europeans have realized that prohibiting such activities is senseless, because gambling generates heaps of money that considerably replenish state budget. In addition, the ban will only lead to an increase in the number of shadow casinos, and a complete lack of knowledge of the state in this sector. Read More

The Difficulty Of Bitcoin Mining Explained

bitcoin-wall

The difficulty of mining process grows as more effort is spent on mining and more bounty hunters join the race. Initially, having a home PC was enough to plunge in Bitcoin mining, then savvy mining gurus moved to utilizing the computing power generated by top gaming graphics cards, but finally the niche has was occupied by digital miners – the devices designed for mining purposes exclusively. At first miners were produced basing on reprogrammed chips, but not so long after application the units based on specific integrated circuits, ASICs, characterized by stunning performance and relatively low power consumption hit the shelves.

For example, the power of a single graphics card Radeon HD 7990 (Nvidia’s solutions are mainly not suitable for mining) equals 1.2 GHs per second at a few hundred watts of energy consumption, while a modern ASIC device, e.g. System Red Fury priced at $125 generates 2.5GHs per second and consumes as little as 2.5 watts. Modern mining implies using ASIC devices, otherwise the affair is commercially unprofitable. Alternatively, one can purchase the necessary amount of GHs via special platforms, e.g. CEX.IO.

Once the miner is purchased the operational expenses are overwhelmingly represented by electricity bills in exchange for Bitcoins. The cost of mining a single Bitcoin may vary from $30 to $600, depending on the equipment used and electricity tariffs. In 2011, buying a top gaming card for mining paid off in about two weeks, but with the growing complexity of the calculation to produce Bitcoins the method is almost useless.

bitcoinMining pool concept

Therefore, miners began to gather in the pools that combine several tens, hundreds or thousands of miners in a single unit: in the case the unit is discovered and mined its share is distributed in accordance with the size of the contribution to the common cause. The system perceives the pool as a miner, producing hundreds of GHs per second, but in practice it is a main server, distributing tasks to miners included in its pool. Unlike solo mining, pool mining generates cash pretty quickly, but in relatively small portions.

In recent months, the media began to cover more and more stories about the unique Bitcoin farms, the largest of which are located in Hong Kong. November, 25 was the launch date of the factory with hardware cooled with liquid cooling, the capacity of which amounted to 4% of the total power in the network or 35 THs per second. It produces about 26 Bitcoins per day, which at the time of writing is equal to tens of thousands of dollars. In April 2013, Kaspersky Lab reported the discovery of a trojan that secretly turns users’ computers in Bitcoin generators.

The Maternity Dress Of Your Dreams

Maternity Wedding DressIf you want to look majestic and solemn on your wedding day, take your time and select a maternity wedding dress carefully. Remember that you will be wearing a dress for a long time, so it should in no way hamper your movability. The models tailored from light and flowing fabrics will make a pregnant bride look like a queen. An elegant addition – a diadem instead of a veil, will certainly emphasise your brilliant look.

Choosing the right fabric

Providing the desired comfort for the expectant mother is possible using the models sewn from lightweight and flowing material. For this reason, pregnant women are best to abandon dresses with corset, which is explained by the fact that these wedding dresses made of heavy taffeta and come with multilayered skirts. Actually, you should better make a choice in favor of dresses with the addition of chiffon, organza or flying and flowing matt silk. All the women who are expecting a baby radiate special energy, and such materials will give ethereal and light feeling. Remember that the material of the dress should be chosen with care, because even the most famous and savvy wedding dress salon will hardly be able to add cardinal changes to the bride’s dress at the supreme moment.

The cut of the sleeves should be special

The wedding dresses for pregnant women have a tiny but very important detail you should pay attention to – the sleeves. The primary requirement is not to overdecorate the sleeves; the trend of the season consists in adding straps, which adds intriguing nudity. If you are on 4-5+ month of pregnancy, the wedding dress should not look similar to the sleeves, because the tummy may become more noticeable, while puffed sleeves may spoil the look by making you look thicker. Check some wedding fashion magazines to find a bunch of photos of wedding dresses for pregnant women, and to see how designers emphasise the sleeves.

Scrap Metal Industry In Europe

Scrap metals are considered to be waste products intended to be processed in order to enter the manufacturing cycle over again. The trend of growing interest in scrap metals is booming not only in Europe and the United States; Turkey, India, China and dozens of other countries are actively buying scrap metal in huge volumes. The explanation is pretty easy to find: scrap metal is way much cheaper than raw iron or copper.

Honestly, the Eastern and Western attitudes towards scrap metals processing are fundamentally different. Therefore, Europeans nourish interest in maintaining free trade of scrap: import and export rates are currently on the crest of a wave here. Since a savvy European scrap metal dealer is interested in searching for prospective opportunities, the number of imported and exported scrap is typically close to be equal. This indicates a high stability of the market and progressive development of market relations.

Western European countries sell scrap in many other countries: Turkey, the Netherlands, Austria, Switzerland and nearly 30 states more to be mentioned. In Germany, France and the UK scrap metal is consumed in higher volumes in comparison with raw minerals. By the way, Germany is the European leader in scrap metal harvesting and processing, as well as export.

In accordance with a research, carried out in the University of Brussels, European dumps will store almost four billion tons of ferrous metal in the coming 25 years. The lion’s share of this volume will be comprised of cars. Scientists forecast that over the 25 years the number of the vehicles produced will outperform the number of cars ever produced before. The consumption boom, according to experts, will naturally be more noticeable in more developed economies.

Konstantin Novoselov About Graphene

Nobel Laureate in Physics Konstantin Novoselov believes that graphene, for investigation of which he and Andrew Geim received a prestigious award, will be applied in the production of high-frequency transistors. Graphene is already available for individual entrepreneurs in the UK (the price ranges from 700 to 2300 pounds).

Now everyone is talking about graphene mainly positively: the material has unique physical chemical properties; it is expected it will revolutionise the world of electronics. This is the first known to man two-dimensional material that conducts electricity as well as copper; thus it grants an opportunity to create touch screens, solar sails for space vehicles, flexible electronic devices and many more.

However, the method for producing graphene, which was pioneered by Geim and Novoselov, initially did not find support in the scientific community. They used graphite rods and duct tapes, glued and then sticking to obtain material with a thickness of just one atom. It was believed that the layers of this thickness will be deformed.

Currently, Novoselov is asked one basic question regarding a better solution for the whole world: is graphene really better than its ‘precursor’, silicon, which is already used in the manufacture of transistors? The question of how the new technology will make another step forward to really take advantage of graphene has to be answered yet.

As mentioned, graphene for private engineering purposes is already available. The world’s first supplier of this material is the company Graphene Industries, registered in Manchester, where Geim and Novoselov live and work. Moreover, the industry is entered by ambitious brain tanks – the graphene companies like 2-DTECH provide guidance on how to integrate the neoteric material, thus accelerating the commercialisation process. The company representatives claim that graphene uses are numerous, and even today the innovative businesses can derive considerable benefits from its use.

‘Right now, we are collaborating with the owner of Graphene Industries, Peter Blake, who sells graphene for studies of biological objects in the transmission electron microscopes’, says Novoselov.

Currently, work is underway on the use of graphene in the creation and super-capacious phenomenally quickly-recharged batteries, particularly for electric vehicles, laptops and mobile phones. ‘Well this is a completely new area, and the results achieved so far do not mean that the full potential is used’, says Novoselov.

Even though the author of the revolutionary invention fails to forecast when will the practical application of graphene technology be used massively and worldwide, Novoselov is still quite optimistic. ‘If I was asked a year ago, I probably would have said ‘never’, but the last year was marked by a major breakthrough in the field of mass graphene production, so at the moment I’m much more optimistic about the practical application of this material’.

According to him, a good indicator of possible applications, it was not what people think in the laboratory, but what big companies plan. ‘The plans for the application of graphene by Samsung suggested experiments with further development to the commercial samples of touchscreen-displays back in 2012, however, the progress is not yet appreciable’, Novoselov says.
