been elucidated, although metabolic effects induced by these agents employed singly have received considerable study and have been discussed in recent reviews (5, 14, 23, 26, 28, 31, 43, 44). The metabolic alteration deemed re sponsible for the tumor-inhibitory effect of azaserine is the blockade of purine nucleotide biosynthesis de novo. Re cent evidence, however, has suggested that this site ...

The purpose of this paper is to analyze the level of system integration among organizations that have deployed intranets or portals. In spite of being independent technologies, portals and EAI have in common the integration issue, and the combined usage of both may produce the synergic effect on application integration processes. The paper presents an instrument to analyze the integration level...

We propose a framework for detecting, extracting and modeling objects in natural scenes from multi-modal data. Our framework is iterative, exploiting different hypotheses in a complementary manner. We employ the framework in realistic scenarios, based on visual appearance and depth information. Using a robotic manipulator that interacts with the scene, object hypotheses generated using appearan...

Pt@TiO2 core-shell nanostructures were prepared through a hydrothermal method. The dye-sensitization of these Pt@TiO2 core-shell structures allows for a high photocatalytic activity for the generation of hydrogen from proton reduction under visible-light irradiation. When the dyes and TiO2 were co-excited through the combination of two irradiation beams with different wavelengths, a synergic ef...

This paper investigates the possible synergic effect of cooperation between firms and main agents Triple Helix approach (academia, industry government) on corporate environmental innovation. The results analysing a broad sample Spanish from various sectors (38,269 observations) over 9-year period show that agents, both individually jointly, increases likelihood Indeed, more involved in with fir...

PVA/CdS nanocomposites with varying amounts of CdS NPs in PVA were synthesized by chemical reduction method and these UV irradiation for different time. Absorption peak around 450 nm observed films indicates presence PVA. causes red shift wavelength absorption spectra which suggests increase particle size after exposure. Decrease transmittance embedding further exposure that can be used UV-bloc...

In the current study, effect of SiO 2 /Na O ratio in Sodium silicate (Na 3 ) solution, Na /NaOH and molarity NaOH on compressive strength geopolymer concrete. A mix design is formulated with various mixes are casted alkali activator solution (AAS) / fly ash (FA) =0.5 constant content. The molar altered from 1.50 to 3.00 for different ratios (2.0, 2.5 3.0) also molarities (8M,10M,12M,14M,16M 18M...
