background & aim: free radicals play a crucial role in the development of tissue damage in various human diseases such as cancer, aging, neurodegenerative disease, malaria and arteriosclerosis, and pathological events in living organisms. antioxidants may have an important role in the prevention of these diseases. the aim of this study is to evaluate potency of scavenging of dpph free radic...

Constructed wetlands have not been commonly used in Vietnam due to the lack of information in the selection of proper types of constructed wetlands, type of reeds, design parameters and performance efficiency, in tropical climates. This paper focuses on Canna generalis, which is a common reed and easy to grow both in water and wet land conditions. Two kinds of hybrid constructed wetlan...

background current teaching suggests increased perfusion in free transverse rectus abdominis myocutaneous (tram) flaps over pedicled tram flaps, broadening indications for its use in high risk patients. this study compared perfusion analysis of free muscle-sparing versus pedicle tram flaps in vivo in the peri-operative and late post-operative periods. methods the spy-elite system using indocyan...

Effective diagnosis and early identification of system problems are crucial to the reliable operation of today’s computer systems. In this article we describe the Melody project, where we apply machine learning in several tools that aim to aid in these tasks in IBM System X servers. Several inherent problems present themselves when developing machine learning tools in this domain. These include...

We propose an implementation of a model-based free-viewpoint TV (FTV) system using only three uncalibrated cameras. FTV is next-generation media that enables us to see a scene from any viewpoint. A modelbased approach for realizing FTV requires real-time 3D object capture using multiple cameras. Here, we propose a system for reconstructing 3D object surfaces using the so-called 2D continuous dy...

We present a semantical proof of existence of normal forms for system F including -equality. A reduction-free normalisation function can be obtained from this. The proof uses the method of glueing (a variant of) the term model along the global sections functor, carried out in the internal language of a category of presheaves. As a by-product we obtain an semantical explanation of higherorder ab...

In a cell-free system from Bacillus subtilis B3, ATP-P1 exchange was catalysed by L-proline at a pH optimum of 7.2. Further stimulation by component amino acids of mycobacillin was inhibited by deprivation from the synthesizing system of even a single amino acid occurring at any point of the cyclic peptide. This inhibition, however, decreased with the distance in the molecule of the given amino...

System reliability often depends on the effort of many individuals, making reliability a public good. It is well-known that purely voluntary provision of public goods may result in a free rider problem: individuals may tend to shirk, resulting in an inefficient level of the public good. How much effort each individual exerts will depend on his own benefits and costs, the efforts exerted by the ...
