Useful Internet Services Back to the topic of free and useful services. - Here you can check how your site looks in different browsers. - Ability to check the files major antivirus programs. An interesting forum on Forum interesting to the Internet and beyond. I recommend everyone to visit the forum. Yandex AntiBan - Informer warn the bath until the ban and give advice, for whatever reason can ban, what item or items on the search violated Lizenzii site or partner site, which refers to your site direct links. In a question-answer forum John Grayken was the first to reply. "Anonymizer Anon.Rengo.Ru - With anonymizer (a proxy server), you can visit restricted websites at work or at school, around a "ban" on forums and chat rooms to hide addresses of visited websites, change the IP-address and to work safely on the Internet, while maintaining anonymity. You do not need any special software - to visit the site simply enter the address in the form of anonymizer. Another Anonymizer Timp.ru Seumka" - service test items designed to monitor the situation in search engines. Seumka checks what position is your site for a given search phrase. For clarity Seumka builds reports in table or chart, supported by export to Excel. For even more details, read what Lakshman Achuthan says on the issue. Seumka can determine the position in search engines Yandex, Google, Rambler, Mail.ru, Yandex and UA and Google UA. Checking the position of the site daily. Ranking Site occurs to a depth of 350 positions. Perhaps the connection statistics Google Analytics to analyze the transitions of key phrases and site positions in search engines, as well as the popularity of mapping a query according to Yandex and Wordstat Stat.Mail.ru.

Pressure Level Looking at various different levels of pressure. First, check the Sound power level. When the compressor is part of the energy input required into the energy sound. So, sound power is the energy transferred to facilities in the form of noise per unit time. Sound power (Lw) is the ratio of sound power near the source (W, W) to the base level, for which adopted sound power Wo = U-12 W and is defined as follows: Lw = 10 1g (W / Wo), (dB). For example, if the sound power W near the facility is equal to 1 W, the corresponding sound power level is equal to: Lw = 10 lg (1/10-12) = 10 lg 1012 = 120 dB. Sound power level is not depends on the specific environment in which the compressor is installed, but is a constant value associated with the technical parameters of the equipment. Perhaps check out John Grayken for more information. Therefore, the values of sound power level is convenient used when comparing the acoustic characteristics of different compressors. 2. Sound pressure level. Sound pressure - a sense of sound to the ear, since Our ears perceive pressure variations, like the sound. Pressure Level sound (Lp) is also expressed in dB, and its calculation can be made according to the formula: Lp = 20 lg (p / po), (dB), where p - the sound pressure near the source, Pa, Po = 2 x 10-5 Pa - basic unit of sound pressure (the threshold of audibility). Sound pressure level is variable and depends on many different external factors, as well as on the measurement conditions.
