Absfract Despite the enormous research efforts in creating new applications with MEMS, the research efforts at the backend such as packaging and assembly are relatively limited. One reason for this is the level of dimculty involved. One fundamental challenge lies in the fact that at micro-scale, micro mechanical structures are fragile and easy to break they typically will break at the micro-New...

Inter-organizational information systems (IOS) play a critical role in today’s organizations and their relationships with business partners. While large organizations began utilizing such systems since their dawn in the 1970’s, SMEs have largely been reluctant to adopt and use these technologies. Given their relative commonness among enterprises, SMEs and micro-firms are particularly well suite...

in the present work a modified in-tube solid phase microextraction technique followed by gas chromatography-mass spectrometry (gc-ms) has been applied for determination of water odorants. geosmin, 2-methyl isoborneol, 2-isopropyl-3-methoxy pyrazine, 2-isobutyl-3-methoxy pyrazine and 2,4,6-trichloroanisol are of the most important odorants which have been studied. in the described method, analyt...

Feedlot performance and mass balance were evaluated on steers fed either 5% untreated corn stover (CON), 20% untreated corn stover (NONTRT), or 20% calcium oxide (CaO) treated corn stover (TRT) when fed with or without saponins (Micro-Aid) in a 3x2 factorial. In both WINTER and SUMMER experiments, ADG, F:G and HCW were improved (P < 0.01) in CON and TRT fed steers compared to NONTRT fed steers....

The objectives of this study were to investigate the feasibility of encapsulating yeast cells using gellan gum by an emulsification method and to evaluate the fermentation efficiency and the reusability of the micro-bioreactors produced. It was found that yeast cells could be successfully encapsulated to form relatively spherical micro-bioreactors with high specific surface area for mass transf...

Muddy intercalation is one kind of rock’s secondary structural surface, where the failure of instability between strata occurred. Mechanical behaviour of muddy intercalation directly affects the stability of the rock mass. Starting from the micro-structure of Muddy intercalation, revealing its macroscopic mechanical characteristic is of great significance to the stability and optimization desig...

Many biopharmaceutical products exhibit extensive structural micro-heterogeneity due to an array of co-occurring post-translational modifications. These modifications often effect the functionality of the product and therefore need to be characterized in detail. Here, we present an integrative approach, combining two advanced mass spectrometry-based methods, high-resolution native mass spectrom...

A rotating torsion balance method is used to detect the product of the photon mass squared and the ambient cosmic vector potential A(e). The signal is modulated by rotating the torsion balance to ensure the effectiveness of detection for all possible orientations of the vector potential. The influences of sidereal disturbances of environment are also removed by virtue of this modulation method....
