Techniques in production

Metal oxide nanomaterials are widely used in many applications of renewable energy. Ytterbium oxide (Yb2 O3 ) also attracts attention due to its similar structure to ZnO (~3,26 eV) and TiO2 (~3,36 eV) in terms of bandgap energy. In this study, Yb2 O3 belonging to the lanthanide oxide family was produced as nanofiber forms by using the electrospinning technique, which allows for large-scale production, for the first time.

In several fish species homozygous and heterozygous clonal lines have been produced using gynogenetic and androgenetic techniques. These lines are standardized and can be reproduced over generations. In rainbow trout such lines have existed for decades and has become important research tools in genome studies as well as in studies of commercially important traits.

Immobilized metal affinity chromatography (IMAC) is a technique primarily used in research and development laboratories to purify proteins containing engineered histidine tags. Although this type of chromatography is commonly used, it can be problematic as differing combinations of resins and metal chelators can result in highly variable chromatographic performance and product quality results.

Food analysis is a tremendously broad field that is constantly evolving. New methods have emerged to increase productivity, such as modern miniaturized and robotic analytical techniques. In this paper, a microsolid-phase extraction system (μ-SPE) for clean-up was combined with a robotic autosampler to yield ready-to-analyze extracts.

This book aims at covering the general concepts of ALM from the point of view of an insurance company or a bank. The core framework and the philosophy are the same, but regulations, products and models typically differ on numerous points in pratice because the business and the risks involved are quite different between an insurance company and a bank. In this book, we have tried to draw a parallel between the uses of ALM in insurance companies and its uses in banks. To our knowledge, this is an innovative way to present and study ALM techniques.

After years of experimenting, the “One must do, five reductions” (1M5R) (in Vietnam referred to as 1P5G), is being promoted by Vietnam’s Department of Crop Production as an advanced technique in rice production. Nevertheless, a certain proportion of rice farmers in the Mekong Delta are reluctant to implement 1M5R.

This research investigated the optimization of injection molding parameters for the minimum warpage of CD & DVD disc substrate of Polycarbonate (PC). CD & DVD disc substrate was first designed by Pro/E 5.0. The Moldflow Plastics Insight 6.1 is used to mesh and simulate the warpage. In order to find out recommended parameters, the study used Taguchi technique in decreasing warpage of CD & DVD substrate.

Lignocellulosic biomass is a potential material source for ethanol production. Particularly, the sugarcane bagasse (SCB) coming from the sugar waste of the refinery is very rich in lignocellulose that can be biochemically transformed into ethanol. However, its recalcitrant structure necessitates a pretreatment step to break up the lignocellulosic matrix, thus improving the accessibility of hydrolytic enzymes to carbohydrates for sugar production.
