Polyurethane/graphene nanocomposites were synthesized using commercial thermoplastic polyurethane (TPU, Apilon 52DE55), and two types of graphene derivatives: graphene nanoplatelets (GNP) and reduced graphene oxide (RGO). Fourier Transformation Infrared Spectroscopy Fourier Transformation Infrared Spectroscopy (FTIR) spectroscopy, TEM, and SEM microscopy and XRD techniques were used to chemical...

We examined the genetic requirements for the Myc family of oncogenes in normal Sonic hedgehog (Shh)-mediated cerebellar granule neuronal precursor (GNP) expansion and in Shh pathway-induced medulloblastoma formation. In GNP-enriched cultures derived from N-myc(Fl/Fl) and c-myc(Fl/Fl) mice, disruption of N-myc, but not c-myc, inhibited the proliferative response to Shh. Conditional deletion of c...

In this work, polypropylene (PP) nanocomposites containing different weight concentration of graphene nanoplatelets (GNP) were prepared by melt-mixing using an industrial-scale, co-rotating, intermeshing, twin-screw extruder. The materials then compression moulded into sheets, and biaxially stretched at stretching ratios (SRs) below the PP melting temperature. effects GNP content biaxial on bul...

Patterns of spending for health during 1986 and beyond reflect a mixture of adherence to and change from historical trends. From a level of $458 billion in 1986--10.9 percent of the GNP--national health expenditures are projected to reach $1.5 trillion by the year 2000--15.0 percent of the GNP. This article presents a provisional estimate of spending in 1986 and projections of spending (under t...

The heterogeneous distribution of delivery or treatment modalities within the tumor mass is a crucial limiting factor for vast range theranostic applications. Understanding interactions between nanomaterial and microenvironment will help to overcome challenges associated with heterogeneity, as well clinical translation nanotheranostic materials. This study aims evaluate influence protein surfac...

Gold nanoparticles (GNPs), have been demonstrated as effective preclinical radiosensitising agents in a range of cell models and radiation sources. These studies have also highlighted difficulty in predicted cellular radiobiological responses mediated by GNPs, based on physical assumptions alone, and therefore suggest a significant underlying biological component of response. This study aimed t...

There has been much recent discussion ahout the ultimate sources of macroeconomic variability. A number ofauthors attribute most of this variability to only B few sowces, sometimes only one. Although there may be only B few important sources, this is fsr from obvious, since economies seem compliested. The purpose of this paper is to provide qusntitstive estimates of various sowces of vsriabilit...

In this review, we present an overview of the technologies in colorimetric biosensors based on DNA-nanoparticle conjugates. Two types of DNA-nanoparticles aggregation assays are summarized. One of the methods relies on cross-linking of the gold nanoparticle (GNP) by hybridization. The crosslinking system was used not only to detect target DNA sequences, but also to detect metal ions or small mo...

objective(s): abdominal adhesions are one of the most important problems, occurring after intra-abdominal surgery in more than 90% of cases. this condition is the leading cause of bowel obstruction, infertility, and abdominal/pelvic pain. gold nanoparticles (gnps) have been shown to be non-toxic and exhibit anti-inflammatory, anti-angiogenic and antioxidant activities. the purpose of this study...

hIn the first section of the study we gave some general informations on the Information Society; for example we have figures showing the contribution of information and communication technologies to GNP and to GNP growth in US; or proving that in “ICT intensive” companies, there is anhigher productivity growth . We mentioned also the growing impact of information society on jobs; it’s quoted an...
