Infection of HeLa cells by mixtures of standard poliovirus and defective, interfering (DI) poliovirus particles leads to a higher ratio of DI particles in the progeny than in the inoculum. The extent of this enrichment could be varied by various manipulations of the co-infected cells. At any time during the infection cycle, virions made within short times after addition of radioactive uridine w...

A PARTICULARLY useful work for the educable mentally defective boy is being done at the Besford Court Catholic Home, Worcestershire, under the administration of Monsignor Newsome. The home is intended for the high-grade "moron," who requires not only< special teaching and training, but also preliminary, concurrent and continuous hospital treatment. For such a child, as the Annual Report points ...

The surface functionalization of diamonds has been extensively studied through a variety techniques, such as controlled oxidation. Several oxygen groups have detected on oxidized diamonds, C–O–C (ester), C=O (ketonic), and C–OH (hydroxyl). However, the composition relative concentration these diamond surfaces can be affected by type oxygenation treatment quality. To investigate stability oxygen...

A technique for determining the characteristics of impulses from implanted cardiac pacemakers with external methods is reviewed, and its value in detecting pacemaker failures is discussed. The resultsfrom a 2-year application with 6ii controls in clinical routine are presented. Sixteen out of b*42 defective pacemakers could be detected before symptoms or electrocardiographic signs of pacing fai...

Fabric defect detection and classification plays an important role in inspection of fabric products. Many fabric defects are very small and undistinguishable, which can be detected only by monitoring the variation in the intensity. Currently, in almost all the fabric industries the process of defect detection is done manually using skilled labor. An automated defect detection and identification...

The silkworm baculovirus expression system is widely used to produce recombinant proteins. Several strategies for constructing recombinant viruses that contain foreign genes have been reported. Here, we developed a novel defective-rescue BmNPV Bacmid (reBmBac) expression system. A CopyControl origin of replication was introduced into the viral genome to facilitate its genetic manipulation in Es...

We describe a PC-based real time machine vision system for the quality assurance of canned tuna at a tin rate over 1,000 tins per minute, allowing the inspection of the tin and its contents, with two main purposes: preventing defective tins from damaging the closure equipment or from reaching the market with a defective closure, and deviating from the production line tins with low quality conte...

Fault prediction will give one more chance to the development team to retest the modules or files for which the defectiveness probability is high. By spending more time on the defective modules and no time on the non-defective ones, the resources of the project would be utilized better and as a result, the maintenance phase of the project will be easier for both the customers and the project ow...

Visual inspection and classification of cigarettes packaged in a tin container is very important in manufacturing cigarette products that require high quality package presentation. For accurate automated inspection and classification, computer vision has been deployed widely in manufacturing. We present the detection of the defective packaging of tins of cigarettes by identifying individual obj...

An inventory management system for defective items with backordered shortages is explored, in which we assume that the quality of an ordered lot is not always 100% perfect, so a screening process to each product is conducted to split that lot into perfect and defective products. Meanwhile, the defective products include imperfect and scrap ones, which will be sold at a discount price and dispos...
