The sea urchin Paracentrotus lividus (Lamarck, 1816) (Echinodermata: Echinoidea) is an important economic resource in Europe, but intense harvesting has led to the collapse of several natural populations. Echinoculture, associated with restocking and stock enhancement practices, alternative this problem. In these procedures, reliable individual identification through tagging a valuable source i...

Recombinant protein purification is a kind of sensitive and expensive method in genetics engineering. Genetic manipulation leads to the expression of various proteins; it should be isolated with high purity finally. Differed methods for protein purification are categorized, based on cast, quality, Easy work and side effect of protein. In this article, we are investigating his His-tag protein pu...

We identified cases where the Jolly-Seber estimator of population size is biased under tag loss and tag-induced mortality by examining the mathematical arguments and performing computer simulations. We found that, except under certain tag-loss models and high sample sizes, the population size estimators (uncorrected for tag loss) are severely biased high when tag loss or tag-induced mortality o...

Milk contains 3-6% of fat, of which the dominant component is triacylglycerol (TAG). Over 100 TAG groups can be readily detected in any non-enriched milk sample by LC-MS; most TAG groups contain several isomers (TAG molecules with different fatty acid composition), which cannot be fully resolved chromatographically by any single stationary phase. TAG profile of mature milk from 19 cows was surv...

The affinity system based on the artificial peptide ligand Strep-tag® II and engineered tetrameric streptavidin, known as Strep-Tactin®, offers attractive applications for study of recombinant proteins, from detection purification to functional immobilization. To further improve binding Strep-tag streptavidin we have subjected two protruding loops that shape its pocket – instead D-biotin recogn...

The concept of a common control model for all tag readers is targeted towards a single interface for all embedded tag reader control and interface programs. We discovered that as we developed a wide range of tag readers certain functionality was common to all of them. We are attempting to develop a standard set of possible control commands that an external agent would need to be able to control...

Tag clouds have become a frequently used interaction technique in the web in the past couple of years. Research has shown the influence of variables such as tag size and location on the perception of tag clouds. However, several questions remain unclear. First, little is know on how tag clouds are perceived visually and which search strategies users apply when looking for tags in a tag cloud. S...

Energy consumption in caches is widely studied topic. The access to a cache line consumes energy. This paper proposes exclusive cache model that reduces the energy consumption over the tag cache model. The proposed model assumes two level exclusive cache with tag cache in level one. The tag cache consists of tag information of all cache levels. It is stored in cache in level one. An address is ...

With the rapid development of the Intemet, information overload and isotropic becomes worse and worse. Personalized services system’s birth partly resolved this problem. The traditional recommendation methods, such as content based recommendation and collaborative filtering, do help a lot. However, to some extent, it couldn’t authentically understand the preference of users. Considered the limi...
