February 2000

Dear subscriber;

Welcome to the first PowerUltrasonics newsletter. This occasional publication is designed to keep you up to date with developments on the site. Please feel free to forward a copy to anyone else you think would be interested.

~~~~~~~~~~~~~~~~ POWER ULTRASONICS ~~~~~~~~~~~~~~~~

The PowerUltrasonics web-site (www.powerultrasonics.com) provides an independent information resource in this field which is surprisingly lacking in books and academic research. Some of the best information comes from the equipment manufacturers, but they are naturally reluctant to provide links
to other information sources on their competitors' sites!

The most popular features are:

• Introduction to power ultrasonics (www.powerultrasonics.com/intro.html) - gives newcomers a basic understanding of the underlying physics and the practical applications.
• Articles about power ultrasonics (www.powerultrasonics.com/articles.html) - links to technical information on the web. I am always looking for more of these so if you know of any please
  let me know.
• Database of suppliers (www.powerultrasonics.com/cgi-bin/suppliers.pl) - searchable by name,
  country, product or service and giving contact details and links to the web-site (if any). Entry to the database is free to anyone providing a relevant product or service.

~~~~~~~~~~~~~~~~~~ WHAT'S NEW ~~~~~~~~~~~~~~~~~~~

Just one new item on the articles page (www.powerultrasonics.com/articles.html) in January. It's a brief report from the Campden & Chorleywood Food Research Association in the UK. "Power ultrasonics improve food quality - Reducing the degree of processing of heat-preserved foods using power ultrasound". Click the link above for more details.

The suppliers database (www.powerultrasonics.com/cgi-bin/suppliers.pl) now contains details of 107 suppliers. There are 2 new product categories:

• Food cutting machinery
• Fluidsonic equipment

and 1 new service:

• Customer funded R&D

If you would like to add any of these to the database entry for your organisation, go to the database page (link above), find your details and click on "Modify". After this, you can select additional products / services from the list by holding down the "Control" key (is it the "Command" key for Mac users?) while clicking on the item.

~~~~~~~~~~~~~~~~~~ VISITOR STATS ~~~~~~~~~~~~~~~~~~

Analysing the server log can extract information about visitors which is vital to the site's future: How many visitors came to the site? How long did they stay, Which pages are popular / unpopular etc. It can also provide a fascinating glimpse of guests dropping in from around the world! At some
stage I plan to create a new page sumarising the latest visitor stats and publish it on the site - I think it might be popular. Here's a quick preview:

PowerUltrasonics visitor stats for January 2000 were most encouraging, despite the server logs going missing for half the month. Irritating, because the last week was the busiest the site has ever been, as the daily record book shows:

Most Hits: 1,672 (Jan 26, 2000)
Most Bytes: 6,574,932 (Jan 27, 2000)
Most Visits: 61 (Jan 29, 2000)
Most Page Views: 638 (Jan 26, 2000)

Here's the visit summary for that week (01:48:25 23 Jan 2000 to 01:36:55 31 Jan 2000):
A total of 3,238 pages were accessed by 212 unique hosts. There were approximately 315 distinct visitors; the typical visitor seems to have spent about 46 minutes visiting the site and to have viewed some 10.3 pages. There were a total of 8,370 hits and 31 errors related to Power Ultrasonics, consisting of 29,290 kilobytes of information.

And here's where January's visitors came from: Australia, United Kingdom, Canada, Turkey, Bulgaria, France, South Africa, United States, Italy, Spain, US Military, Mexico, US Educational, Brazil, Poland, Switzerland, Jordan, Romania, United Arab Emirates, Thailand, Israel, New Zealand (Aotearoa).

~~~~~~~~~~~~~~~~~~~ WEB POSITION ~~~~~~~~~~~~~~~~~~

PowerUltrasonics is a highly specialised web-site looking for a world-wide audience with a zero advertising budget! In this situation, search engine positioning is VERY important.

I use WebPosition Gold to manage submissions and automatically track where the site appears in results for lots of popular seach phrases - a task that would be a full-time job if done manually. It will also analyse web pages and suggest ways of improving their ratings! If you think your web-site
could benefit from this kind of service, you can download a free version (limited to only 3 search engines) by following the link below:

http://www.webposition.com/cgi-local/index.pl?DS1=RP&DS2=ELG-55E5

Note - This is an affiliate programme. If you download, and subsequently decide to buy the product I will receive a small commission. Nevertheless, I endorse Web Position because I really believe in it and use it regularly myself (honest! ;-)

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

That's all for this time. Feedback is always welcome...
