This study examines factors that influence users' adoption of mobile services. Using data collected from mobile phone users in China, we compare adopters' and non-adopters' perceptions on mobile services using a general model. Structural equations modelling testing results show that perceived usefulness and perceived service cost affect mobile service adopters' and non-adopters' perceptions, while perceived trust and perceived trialability affect adopters' attitude towards continued usage and non-adopters' attitude towards usage differently. Our results have implications for mobile service providers in future product development and service improvements.

Application note issue #5 - Cement Analysis August 2017
Cement analysis using FP program (Fundamental Parameters) Cement is a blend of several minerals. It is critical to control the elemental composition and properties such as strength, setting, time and color. ED-XRF is being used to analyze the raw components, raw meal, clinker, and the final cement product (Na, Mg, Al, Si, S, K, Ca, and Fe in Cement, Clinker, and Raw Meal).XRF is at the heart of the control of the production process in any modern cement works and is central to the ability of the cement maker...
Analysis of precious metals in jewelry
AbstractFor thousands of years, man learned the craft of making jewelry from gold. Gold is a noble metal which does not react with the air and has a shiny yellow color.Over the years, alloying of the gold was necessary to improve its properties since pure gold is too soft to be used for jewelry. Alloying of the gold is usually by low-cost metals such as copper, zinc, silver or nickel. Since different metals have different financial value, which determines the value of the jewelry, it is important to accurately...
Quantitative Analysis of Geological Samples- X-Calibur
Abstract Quantitative and qualitative analysis of geological samples (rocks and river sediments) was performed on Xenemetrix EDXRF Benchtop Spectrometer System, model X-Calibur Objective: Perform XRF measurements on certified geological reference materials to build calibration curves for the major oxides (Na2O, MgO, SiO2, Al2O3, SiO2, P2O5, SO3, K2O, CaO, TiO2, MnO and Fe2O3) and for trace elements Cr, Co, Ni and Pb in these samples. Quantify geological samples of unknown concentrations with respect to...
Quantitative analysis of iron in flour
Abstract A quantitative analysis of Iron in flour via Xenemetrix EDXRF Laboratory Spectrometer System was performed by model EX-3600M. The minimum detection limit for Fe in flour matrix was determined to 0.8 ppm at 3 sigma. Objective To design an easy method by using EDXRF technique for quick and convenient measurements of Fe in flour at the level of tens of ppm. Background EDXRF is a fast and non-destructive technique that can quantify any type of samples in solid, powder or liquid form within a few...
Return on Investment Using MANTECH Multi-Parameter Analysis Systems - Case Study
Since 2008 Eurofins has been using MANTECH systems at various facilities around the world. Their first system ran 200,000 samples in five years. The unit analyzed 7 different parameters per sample and operated 24 hours/day, 7 days/week. This generated €5,000,000 in revenue. Their initial investment was €60,000. The system discussed in this case study analyses pH, conductivity, alkalinity (speciated), turbidity and absolute color from a single 50ml tube. The cost per sample was 0.91 Euros. After factoring...
