Utilizing the Steam Power of Tile Floor Cleaner to Clean Up After Pets

Lauren Zwiebel — Tue, 29 May 2012 08:33:04 GMT

Caring for a pet means a whole lot more than just buying a nice cage or comfy bedding. In addition to comfort and space, pets deserve a clean living environment. And to ensure that, you should clean its cage and bedding on a regular basis. If urine, vomit, or fecal matter is not attended to immediately, your pet can get sick. The offensive smell is another major issue. Your pet is unlikely to appreciate having to live in a cage that smells bad. A dirty pet cage can harbor fleas an...

Latest analytical technology ensures biogas efficiency

Sustainability in a competitive world - A new carbon order emerges

Tom Delay — Mon, 28 May 2012 07:10:50 GMT

A growing global presence, a rising political power, a burgeoning consumer market are all terms associated with China. But, `a voice for sustainability`? This doesn`t tally with most people`s perceptions of the country, which emits more CO2 than the US and Canada put together - up by over 170% since 2000[i] - and has recently been in the spotlight for not declaring its airline`s carbon emissions. And so it was truly surprising when an online research project that we recently conducted with TN...

Sulfur Compounds Analyzer MEXA-1170SX

Shinichi Murakami — Fri, 25 May 2012 12:24:34 GMT

The MEXA-1170SX is a continuous gas analyzer for sulfur compounds existing in engine emissions. It can measure SO2 concentration and the amount of total reduced sulfur compounds (TRS), such as H2S, separately. It can also measure the total sulfur compounds (TS) that contains both gaseous compounds and liquid compounds in PM, such as SO3. By utilizing ultra-violet fluorescence (UVF) method and various original analysis techniques such as ozone injection, the MEXA-1170SX achieves reliable measu...

Low-mass PM analyzer MEXA-1370PM — Improvement of the Performance for PM Composition Analysis —

Masayoshi Shinohara;Tomoshi Yoshimura — Fri, 25 May 2012 12:23:29 GMT

Particulate matter (PM) emitted from engines is currently measured by the filter weight method. The filter weight method passes diluted emission gases through a filter collecting the PM, and post test weighs the mass of the collected PM on a precision balance. However, this method is time consuming, and with decreasing PM emission volumes, improvements in accuracy were needed. So the MEXA-1370PM was developed, to measure soluble organic fraction (SOF), soot, sulfate and total PM by vaporizing...

Automotive Development and Progress in HORIBA`s Emission Measurement Technologies

Hiroshi Kawamura — Fri, 25 May 2012 12:14:30 GMT
