Oil and Gas sector, with notable participation in national product and funding public expenditures, plays a seminal role in Iran's economy. Although there is a relative lag in providing proportionate supply, Iran stands at the highest rank of owning world's related proven reserves. Using a Computable General Equilibrium (CGE) model, this study was aimed to investigate the effects of the increas...

This study aims to investigate the influence of graphene nanoplatelet (GNP) concentration on electrochemical and tribological properties GNP-poly(methyl methacrylate) (PMMA) composite coatings. GNP-PMMA coatings were prepared with varying GNP concentrations (0.5, 1.0, 3.0, 5.0 wt %) using drop-casting method onto AA6061 aluminum alloy substrates. Results showed that addition 1.0 % increased ten...

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...
