Abstract:

A number of exoglycosidases have been prepared from bacterial and plant sources using established methods for the separation of enzymes, in conjunction with certain novel purification systems hitherto not described in the literature for these enzymes. The enzyme, beta-galactosidase from E. coli has been prepared using previously described methods of phase separation and ion-exchange chromatography. As a final step in this purification, the use of a new hydroxyl-rich chromatographic support for the isolation of high-grade enzyme suitable for use in enzyme immunoassays was investigated. Methods

Abstract:

Biorefineries allow for the sustainable production of higher value products from biomass. In addition to bioethanol, they can produce added value chemicals and pharmaceutical intermediates from isolated component compounds such as sugars. Sugar beet pulp (SBP) is a high volume, low value by-product from sugar beet processing with a low lignin and a high carbohydrate content, making it an attractive biomass feedstock for biorefinery processing. The pectin fraction of SBP can be isolated via steam explosion, which, after complete acid hydrolysis, gives a hydrolysate rich in monosaccharides: prim

Unfortunately, even with the optimization of the parameters involved in the electrofiltration, the only DNA that can pass through t

Fault detection and isolation (FDI) is essential for dependability of complex technical systems. One important application area is automotive systems, where precise and robust FDI is necessary in order to maintain low exhaust emissions, high vehicle up-time, high vehicle safety, and efficent repair. To achieve good performance, and at the same time minimize the need for expensive redundant hardware, model-based FDI is necessary. A model-based FDI-system typically comprises fault detection by means of residual generation and residual evaluation, and finally fault isolation. The overall objectiv

An experiment generates a protein association matrix wherein each column represents a sample from one bait protein, each row represents one prey protein and each cell contains a presence/absence associat

Abstract:

In recent times research has returned to focus on the development of sustainable alternatives to fossil fuel based transport fuels. The drivers for this research are the twin issues of improving supply security and concerns over global warming caused by increased greenhouse gas emissions. For a competing fuel to be economically viable it must be cheap to produce, be compatible with existing fuel infrastructure, and not impact upon conventional agriculture. Butanol produced from the fermentation of waste lignocellulose as a feedstock fits the bill for the requirements of a sustainable fuel prod

Difficulties with reproducibility of isolation yields when distilling 211At from irradiated bismuth targets led us to use a “wet chemistry” approach for that process1. The wet chemistry approach has provided 211At isolation yields of ~ 78 % after decay and Bi attenuation corrections2. However, the use of diisopropyl ether (DIPE) in the separation process has made it difficult to reach our goal of automating the 211At isolation. Therefore, we have investigated the use of column materials to simplify the isolation of 211At and remove DIPE from the process. In this investigation we evaluated the

Abstract:

A two-step protocol has been devised as a rapid and selective alternative to conventional differential extraction techniques with an increased recovery of DNA. The protocol involves pressure cycling with the Barocycler® NEP 2320 from Pressure Biosciences. Inc. in alkaline conditions for epithelial cell lysis and removal. This step is followed by alkaline lysis at 95º C for extraction of sperm cell DNA. At 1:1 or 2:1 female to male cell ratios, high selectivity and complete separation can be achieved. But at higher ratios, male allelic dropout is observed. This protocol has been modified to gen

Abstract:

Depuis le développement des composants d'électronique de puissance qui ont permis la fabrication d'onduleurs fiables et efficaces, les entraînements à vitesse variable utilisant des moteurs asynchrones sont devenus de plus en plus populaires. La technique MLI s'est avérée être une méthode très efficace de contrôle de la vitesse de rotation. Cependant, les impulsions de tension, avec des pentes très raides (de l'ordre de quelques kV/µs), ont apporté de nouveaux risques pour le système d'isolation électrique des moteurs. La richesse harmonique de la tension MLI entraînera une surtension signific

Abstract:

Foi realizado um estudo para verificar a ocorrência de leveduras do gênero Rhodotorula, em hemocultura por um período de 8 anos. Os pacientes identificados foram descritos clinicamente segundo variáveis de interesse incluindo dados sobre terapêutica e desfecho. Determinou-se também as concentrações inibitórias mínimas de 20 cepas frente a diferentes antifúngicos de acordo com NCCLS e EUCAST. Realizou-se tipagem molecular através da cariotipagem eletroforética em campo pulsátil<br>A study was conducted to verify the frequency of occurrence of Rhodotorula spp. from blood cultures over an 8-year
