How to choose best lifting equipment provider

Whatever the industry is and regardless of the product, it is very important to choose the right lifting equipment. The fact is that clever lifting equipment installation will save both time and cost. It will also ensure that the users of lifting equipment do not have to install the equipment again if any changes are required. It is not easy to move lifting equipment as it is heavy and can become a cause of fatality as well. (more…)

Free VPN services – can they be trusted?

Privacy has now become quite a buzzword on the Internet. Even the most frequent users of web media become aware of the transmission of some personal data. However, you may not worry, because there are many ways, which you can use to increase the safety of your information.

The best variant for everyone to provide the safety is to use a virtual private network (VPN) to encrypt all incoming and outgoing data. So what is this Virtual Private Network? First of all, VPN allows you to connect the device to a virtual network, which in turn encrypts the transmitted information by hiding it from the public. A good VPN will keep a record of your browsing history, which means that you are an anonymous user. You may use your virtual private network to get the access to the sites that are not available in your region.


Discussing medical negligence from a legal standpoint

The problem of medical errors is one of the most important areas in medical law. The number of medical errors, unfortunately, is growing with years. For example, in the US, the number of victims of medical errors annually varies from 40 to 87 thousand people. In this regard medical errors kill less people than AIDS. By the most conservative estimates, the economic damage caused by medical mistakes each year in the United States is equivalent to the state budget of an average European economy. Thus, in the jurisprudence more and more medical malpractice cases are started (criminal and civil ones). Medical personnel is attracted to criminal liability, and medical clinics are suffering huge losses in the form of payments as compensation for non-pecuniary damage and harm caused to a patient. But in this chain a number of other organisations is also involved – insurance companies and pharmaceutical firms. The first ones are required to pay large sums to patients and then placing recourse action of medical institutions, which can be a beginning of the end for the medical facilities. Pharmaceutical companies, in turn, can also be held liable, for example in case of delivery of substandard pharmaceuticals.

From all this it follows that it is necessary to answer two important questions. The first one: what medical error? The second question is more complicated: which medical errors entail increased responsibility for the doctor, and which ones do not imply any increased responsibilities for the doctor? Defining a medical error is not a simple task. Plenty of literature offers a point of view that if a doctor has committed a medical error, there are already grounds for bringing, for example, a physician, to criminal liability. However, this may be a fundamentally wrong approach, compounded by the fact that, as a rule, the investigator and preliminary investigator, do not delve into the intricacies of medical practice, medical ethics and do not analyse the jurisprudence of this category of cases.

The fact is that so far neither the majority of medical nor law schools teach the fundamental courses of the application of medical law. All this leads to an incorrect legal qualification of acts, so judging the case on medical errors (especially criminal) is a tricky and a complicated process. The situation is sometimes corrected in the presence of legal counsel, having proper practice, for example, in the US, the UK and Germany there are law firms, employing lawyers specialising exclusively on medical and pharmaceutical law. According to SolicitorsGuru, one of the fastest growing legal services aggregators in the UK, there are 1753 results on medical negligence solicitors – a quite modest number for the country with 64ml. population and increasingly alarming tendencies of growth in the number of new cases (+5.6% in 2013 in comparison with the previous one). Many people who are seeking for professional help comes to a decision to not only win a case but not to pay large fees – there are details about no win no fee deals on the aforecited website. As we see, keeping in mind the increasing number of court approvals (just 37% of claims resolved without any damages paid), in practice the cases where medical personnel errors are justified are not that huge in percentage ratio.

Plasma use in effective disposal and its production capabilities

Plasma-chemical technology is primarily used for the processing of highly liquid and gaseous wastes. Thus, it is not only about hazardous waste disposal, but about the production of valuable commercial products. The process is carried out in the plasma torch by electric arc energy at a temperature above 3,000 – 4,000°C. At this temperature, oxygen, and any waste are cleaved to electrons, ions and radicals. The degree of decomposition of toxic waste reaches 99.9995%, and in some cases it rises up to 99,99998%. High energy costs and the complexity of the problems associated with plasma-chemical technology determine its application to processing only those waste types disposal of which does not meet environmental requirements.

plasma001The prospective application of a plasma method is processing waste in a reducing atmosphere to produce valuable commodity products. In modern economies the technology of pyrolysis of liquid organochlorine waste and reducing the low-temperature plasma, allowing to obtain acetylene, ethylene, hydrogen chloride and products based on them are added to the arsenal. Such companies as Simdean, a seasoned manufacturer focusing on innovative plasma waste disposal and industrial waste disposal methods, has launched the mass production of such plasma stations. According to the the company’s report published on September, 25 in 2014, the cost-effectiveness of the method is confirmed during the 2nd or 3rd year of utilisation, despite the huge investments needed for installation or modernisation of an enterprise (eco-friendliness and meeting certain standards plays a vital role here – this is where economical preferences matter).

Raw materials in construction products manufacturing: lime in focus

Lime is a very important material that is largely used in the construction and repair industries. Lime is oftentimes added to various surface treatment solutions (e.g. whitewashing or restoration). The structure of this material consists mainly of calcium oxide. In case lime is used to whitewash or knead some solution, it would be required to slak it. Hydrated lime is obtained from the lump. Slaking means pouring the water and kneading it until it gets smooth. Lime is oftentimes classified into quick (the process takes up to eight minutes), moderate (the process takes up to 25 minutes) and slow (the process takes more than 30 minutes) types.

There are a few binders which relate to the hydraulic lime group. Lime itself represents a binder, which is used for the preparation of various solutions and widely used during the repair or construction works. Lime can be be lump or ground. For slaking ground lump is used as the hardening of this material takes place in the air after treatment with water. Slaked lime or hydrated lime is often added to the dry mixture to ensure protection from various pests. If lime is slaked in dough, it can be stored in for a very long time, and the quality of this dough gets even better.


The Prospects Of Ultrasound Use In Molten Metal Processing

The presence of metals and their alloys in even hundredths and even thousandths of a percent gases and non-metallic impurities significantly reduces their strength and ductility. To purify metal from unwanted impurities gases, oxides, nitrides, and other non-metallic inclusions a set of technological operations that can be combined under the term of refining is developed. The process of refining is an absolutely vital part of improving the quality of metals and alloys.

Purification of the liquid metal from non-metallic inclusions is to separate the melt surface tiny gas bubbles and particles of oxides, nitrides, sulfides, and other compounds which normally remain in the melt and fall into an ingot. In recent years, combined methods for refining are gaining momentum – physical and adsorptive methods are meant. Absorptive refining method implies introducing inert or reactive gases into the melt to have impurities decomposed into gaseous products. Due to the low pressure gas within these bubbles is diffused in the dissolved metal hydrogen, nitrogen, and other gases and bubbles are adsorbed on the surface of the solid particles of nonmetallic inclusions. After achieving considerable size bubbles refining agents resurfacing molten metal. For sufficiently complete removal of non-metallic inclusions from the melt must pass through metal refining a large number of substances, which is not always appropriate and feasible.

Physical refining methods, e.g. vacuuming, require additional equipment and time to process metal.
