We have renormalized a classical left-right model with a bidoublet, and left and right triplets in the Higgs sector. We focus on oblique corrections and show the interplay between the top quark, heavy neutrinos and Higgses contribution to the muon ∆r parameter. In the SM, custodial symmetry prevents large oblique corrections to appear. Although in LR models there is no such symmetry to make van...

The cohomology of moduli spaces of curves has been extensively studied in classical algebraic geometry. The emergent field of tropical geometry gives new views and combinatorial tools for treating these classical problems. In particular, we study the cohomology of heavy/light Hassett spaces, moduli spaces of heavy/light weighted stable curves, denoted as Mg ,w for a particular genus g and a wei...

The objective of this research is to investigate the advantages of using large-diameter 0.7 inch prestressing strands in pretention applications. The advantages of large-diameter strands are mainly beneficial in the heavy construction applications. Bridges and tunnels are subjected to a higher daily traffic with an exponential increase in trucks ultimate weight, which raise the demand for highe...

This paper presents the results of comprehensive laboratory work conducted for investigating mechanical and radiation attenuation characteristics heavyweight concrete produced with pyrite, chromium, magnetite aggregates normal weight concretes three different water/ cement (w/c) ratios. Various experiments were to determine compressive strengths, ultrasound transmission velocities, experimental...

The controversy over the use of nuclear energy fundamentally comes down to three main considerations: its safety of use, ability of nuclear energy generation to reduce greenhouse gas emissions and finally its long term sustainability. The paper addressed the problem of safety in the industrial and medical use of nuclear energy, as it is affected by the design and construction of light and heavy...

Document summarizes a procedure to establish pay factors for asphalt concrete pavement construction using performance models for fatigue and rutting based on the analysis of accelerated pavement tests from the Caltrans Heavy Vehicle Simulator (HVS) and the WesTrack accelerated pavement performance test program. Results of the performance-based approach are compared with pay factors determined b...

On April 26, 1986, at 1:23 a.m., a chain reaction occurred in the Chernobyl reactor, creating explosions that blew off the reactor’s heavy steel and concrete lid. From Chernobyl in the former Union of Soviet Socialist Republics (now in the Ukraine), radiation spread across Europe in perhaps the most catastrophic industrial event in the planet’s history. Radioactive particles remained suspended ...

Weather nowcasting is a meteorological forecast which alerts civil protection institutions in case of heavy rain events, tornadoes, fires or heat waves and so on. This technique needs to process different data in a very short time. This paper, critically describes the design process of a computational infrastructure for weather nowcasting using both web and Grid technologies as a suitable solut...

A survey is given on the various options to seal water ingress from strata and from concrete structures by injecting different types of resins showing the scope and limits of the individual grouts. The report covers methacrylates and polyurethane hydrogels, one and two component polyurethane resins as well as silicate isocyanate resins. The use of fast reacting two component polyurethane resins...
