The analysis and processing of large data are a challenge for researchers. Several approaches have been used to model these complex data, and they are based on some mathematical theories: fuzzy, probabilistic, possibilistic, and evidence theories. In this work, we propose a new unsupervised classification approach that combines the fuzzy and possibilistic theories; our purpose is to overcome th...

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...

The world is experiencing new relations and transformations between natural, synthetic, digital substances. Rather than considering these as materially distinct or ontologically separate, this Special Issue of TSANTSA interrogates how they are interlocked in socio-material processes mediation, transmutation, valuation. By conceptualizing the specificity their separateness, special issue makes p...

Estimates of covariance components and genetic parameters were obtained for birth, weaning, 200-d, and 400-d weight for a herd of Polled Herefords and a herd of a multibreed synthetics, the so-called Wokalups. Data originated from an experiment in Western Australia selecting for preweaning growth rate. Analyses were carried out by REML fitting an animal model including genetic and permanent env...

Until about the 1960s the UK firm of Courtaulds was essentially a produccr of man-made fibres, almost wholly of the ccllulosics (viscosc and acetate), which wcrc bcing displaced in the post-1945 years by thc synthetics (nylon, acrylic and polyester). Courtaulds had entered this field in the carly 1900s and pioneered within the decade as a fibre multinational with the setting up of the American ...

A general inversion scheme based on a genetic algorithm is developed to invert seismic observations for anisotropic parameters. The technique is applied to the inversion of shear-wave observations from two azimuthal VW data sets from the Conoco test site in Oklahoma. Horizontal polarizations and time-delays are inverted for hexagonal and orthorhombic symmetries. The model solutions are consiste...

The importance of operative correction of congenital and acquired defects of the diaphragm has been well demonstrated by the numerous articles published on this subject over the past 30 years. The site and size of the diaphragmatic defect will seldom prevent primary closure; when it does, different methods of plastic repair can be employed (Gross, 1911; Sauerbruch, 1928; Rehn, 1919; Rives and B...

Camptothecin or CPT and its analogs appear to employ anticancer action by poisoning topoisomerase I (topo I) enzyme. As a result topo I activity inhibited and have established important role against a wide range of tumors. CPT was extracted from bark of Chinese plant Camptotheca acuminate but now a large number of synthetic and semi-synthetics are identified. After activity, researchers organiz...

Anyone who has ever played on grass or had an unplanned encounter with a bush knows that plants contain pigments which adhere to varying degrees to fabric (and skin!). The fact that a small industry has risen up in aid of attempts to remove stains like these and many others shows that not all of the molecules can be treated in the same way if their removal is desired. Part of the reason behind ...
