We are now launching the first issue of the first volume of the International Journal of Analytical Mass Spectrometry and Chromatography (IJAMSC). This newly launched journal is an open access journal, whose primary aim is to provide a platform for researchers and practitioners, worldwide, to promote, share, and discuss various new issues and developments in all areas of Mass Spectrometry and C...
Liquid secondary-ion mass spectrometry (liquid SIMS) is an obsolescent ionization technique that revolutionized the analyses of large biological molecules in the 1980s. The term includes fast atom bombardment mass spectrometry (FAB-MS). The technique has been largely superseded by electrospray ionization. This account will cover the history of the technique, the principles of the operation, and...
A novel analytical method, called Liquid Phase Ion Mobility Spectrometry (LiPIMS) was demonstrated, where aqueous phase analytes were ionized and introduced into non-aqueous liquids, transported by an external electric field from the point of generation to a collection electrode. Ions were produced from a unique liquid phase ionization process, called Electrodispersion Ionization. Spectra of an...
مدل های تدوین استراتژی کلان به ارائه کلی ترین استراتژی شرکت در سطح کل سازمان پرداخته و مشخص کننده نحوه جهت گیری استراتژی های اصلی و حرکت سازمان هستند. هر یک از این مدل ها دارای دو دسته فاکتور بوده که به بررسی توان داخلی و جذابیت خارجی سازمان می پردازند. مفهوم منحنی دوره عمر سازمان دیدگاه نسبتاً جامعی درباره وضعیت درونی سازمان ها ارائه می کند. می توان با روشی مشخصی، موقعیت سازمان را در منحنی دو...

Clustered servers for Internet service is a popular solution to cope with the explosive increase in client requests. The high probability of service failure in cluster servers make the cluster management system necessary to provide high availability and convenient administrator control. In this paper, we present the design and implementation of a load cluster management system (LCMS) based on S...
A Liquid Chromatography-Combustion (LC-C) Interface, based on a moving wire technique, has been built and tested. The LC effluent is deposited onto a transport wire, which carries the sample through solvent evaporation and combustion ovens. CO, from the combustion step is analysed in an isotope ratio mass spectrometer. Performance of the interface was tested by loop injections of sucrose and gl...
We describe a novel LCMS approach to the relative quantitation and simultaneous identification of proteins within the complex milieu of unfractionated Escherichia coli. This label-free, LCMS acquisition method observes all detectable, eluting peptides and their corresponding fragment ions. Postacquisition data analysis methods extract both the chromatographic and the mass spectrometric informat...
The 2016 10th Workshop on Recent Issues in Bioanalysis (10th WRIB) took place in Orlando, Florida with participation of close to 700 professionals from pharmaceutical/biopharmaceutical companies, biotechnology companies, contract research organizations, and regulatory agencies worldwide. WRIB was once again a 5-day, weeklong event - A Full Immersion Week of Bioanalysis including Biomarkers and ...
To cope with the explosive increase in the number of requests to Internet server systems, one popular solution is a load-balancing technique that uses a dispatcher in the front-end of a cluster farm. A cluster group is viewed as a single system image with very high performance and also gives a good scalability. But a failure in any single host in a cluster group can cause an overall system fail...
