USP <1217> “Tablet Breaking Force”: A New Chapter for Tablet Hardness Testing
The new USP chapter <1217> “Tablet breaking force” in USP 31 NF6 describes important concerns of Tablet Hardness Testing users:
- Comparability of results obtained from constant loading rate measurements and constant plate movement measurements. Hardness test results may vary from plant to plant, country to country or ...
The installation of an 802.11b Wireless LAN system to cover a large office setting can be very challenging and techniques found in cellular system engineering are often required. WLAN systems have the added complexity of operating in an unlicensed band where interference may not be under control of the WLAN manager, and the WLAN often operates in a harsher indoor RF environment. Large WLAN ...
This portable dual-channel unit performs propagation analysis, CW testing, site verification, and signal-strength analysis.
Receiver Speeds Base-Station Siting For PCS
Site planning is essential to the devel- opment of wireless networks that pro- vide the best coverage using the few- est base stations. One example of this is the roll out of personal-communica- tions-services (PCS) systems. Due ...
Cleaning validation for production equipment at pharmaceutical facilities is an important process for ensuring quality control and safety. HPLC is often used for evaluation and testing, but can become complicated and time-consuming when sample preparation requires the use of solvent extraction or enrichment, etc. An alternative is the swab/direct combustion carbon analysis method using a Total ...
What is the best way to measure rancidity in my sample? That is an often asked and simple question that, unfortunately, belies a simple answer. Many factors must be considered when selecting the most appropriate test or series of tests, and it is often difficult to predict which method will yield the most meaningful results.
What Causes Rancidity? Fats and oils play an important role in the ...
Berkeley Varitronics Systems has developed three CDMA Pilot PN scanners that are currently being used to diagnose and remediate problems in CDMA networks. This article presents some of the problems that have been found and diagnosed with pilot scanners. Other potential problems in CDMA networks are addressed, and CDMA Field tools capable of diagnosing these potential problems are introduced. ...
