Advanced LIGO

The Advanced LIGO gravitational wave detectors are second-generation instruments designed and built for the two LIGO observatories in Hanford, WA and Livingston, LA, USA. The two instruments are identical in design, and are specialized versions of a Michelson interferometer with 4 km long arms. As in Initial LIGO, Fabry-Perot cavities are used in the arms to increase the interaction time with a gravitational wave, and power recycling is used to increase the effective laser power. Signal recycling has been added in Advanced LIGO to improve the frequency response. In the most sensitive frequency region around 100 Hz, the design strain sensitivity is a factor of 10 better than Initial LIGO. In addition, the low frequency end of the sensitivity band is moved from 40 Hz down to 10 Hz. All interferometer components have been replaced with improved technologies to achieve this sensitivity gain. Much better seismic isolation and test mass suspensions are responsible for the gains at lower frequencies. Higher laser power, larger test masses and improved mirror coatings lead to the improved sensitivity at mid and high frequencies. Data collecting runs with these new instruments are planned to begin in mid-2015.

Probing minimal supergravity at the CERN LHC for large tan beta

For large values of the minimal supergravity model parameter tan beta, the tau lepton and the bottom quark Yukawa couplings become large, leading to reduced masses of tau sleptons and b squarks relative to their first and second generation counterparts, and to enhanced decays of charginos and neutralinos to tau leptons and b quarks. We evaluate the reach of the CERN Large Hadron Collider (LHC) pp collider for supersymmetry in the MSUGRA model parameter space. We find that values of m((g) over tilde) similar to 1500-2000 GeV can be probed with just 10 fb(-1) of integrated luminosity for tan beta values as high as 45, so that MSUGRA cannot escape the scrutiny of LHC experiments by virtue of having a large value of tan beta. We also perform a case study of an MSUGRA model at tan beta = 45 where (Z) over tilde(2)-->tau<(tau)over tilde>(1) and (W) over tilde(1)-->tau(1)nu(tau) with similar to 100% branching fraction. In this case, at least within our simplistic study, we show that a di-tau mass edge, which determines the value of m((Z) over tilde 2) - m((Z) over tilde 1), can still be reconstructed. This information can be used as a starting point for reconstructing SUSY cascade decays on an event-by-event basis, and can provide a strong constraint in determining the underlying model parameters. Finally, we show that for large tan beta, there can be an observable excess of tau leptons, and argue that tau signals might serve to provide new information about the underlying model framework.

O desafio de desenvolver artistas criativos no mundo das mídias digitais

From the second half of the twentieth century, with the proposal of working active listening, exploring sounds, the experience, the search for new forms of contemporary music notation, improvisation and experimental music composition, arise music educators Paynter Schafer and Koellreutter, known by the active method of second generation who contributed greatly to the development of creative processes in the classroom. Also arises, in the same period, the encounter between art and technology, expanding opportunities through digital media, open, participatory and interactive works such as Video art, Web art, Nanoarte and Locative Art, augmented, not only against the art with the public, through connections mediated by digital interfaces, providing new learning situations attractive for the development of creativity and artistic production as challenges in contemporary.

Cana-de-açúcar e álcool combustível: histórico, sustentabilidade e segurança energética

The cane sugar is important since the early days in the history of the country, following the discovery of Brazil since the colonial period, therefore, the culture has an important role in the Brazilian economy, being one of the main products. In the 1970s with the advent of the economic crisis, geopolitical and the possibility of depletion of oil, countries dependent on imported fuel, sought new energy alternatives. In Brazil, it was decreed in 1975 the creation of the National Alcohol Program - PROALCOOL, who had several years of rising, the increase of distilleries and marketing of cars powered with ethanol blend. Due to the decrease in the price of oil the importance of the program significantly reduced, returning to peak only in 1979, ie, the second phase of the program. Conceived as one of the vectors of the national response to the crisis in oil prices '70s, the program persisted at times rising in others not reaching for more than three decades. Brazil is the second largest ethanol producer, second only to the U.S., where the raw material comes from corn, which becomes a bottleneck biodiesel production because it competes with food production. New technologies developed to increase ethanol production combined with sustainability and economic viability are being held, the principal is the second generation ethanol, known as cellulosic ethanol, ethanol plus third and fourth generation.

Determinação do teor de glicose em bagaço de cana-de-açúcar hidrolizado pelo processo de conversão enzimática

The production of ethanol and sugar from sugarcane juice generate as byproduct, the bagasse. Currently, the bagasse, an industrial lignocellulosic biomass, can be used for production of second-generation ethanol, since when it is submitted to hydrolytic processes generates fermentable sugars. The objective of this study was to produce fungal enzymes capable of hydrolyzing this lignocellulosic biomass to generate glucose. For this, we used the mushroom species Lentinula edodes, Pleurotus ostreatus, Pleurotus eryngii, and Pycnoporus sanguineus as potential sources of laccase, manganese peroxidase and lignin peroxidase enzymes, capable of hydrolyzing the crushed sugarcane. The hydrolysis process was performed with the highest enzymatic activities observed from laccase in L. edodes (39.23 U-mL after 25 day incubation), P. ostreatus (2.5 U U-mL after 27 day incubation), P. sanguineus (80 U-mL after 27 days of incubation) and P. eryngii (16.45 U-mL 15 days incubation). MnP and LiP showed no significant results. The enzymatic hydrolysis of sugarcane bagasse in natura (32,17% hemicellulose, cellulose 52,45% and 10,62% lignin) and bagasse hydrolyzate with 7,0% H2SO4 (0,20% hemicellulose, 68,82% to 25,33% cellulose and lignin) were evaluated for each enzymatic obtained. Compared to others, the enzymes produced by P. sanguineus incubated in sugarcane bagasse showed better efficiency resulting in glucose with an average content of 0,14 g-L. Although the levels of glucose determined in this work were low in relation to the literature, it can be stated that the laccase, manganese peroxidase and lignin peroxidase enzymes demonstrated good hydrolytic potential, especially those produced by the fungus P. sanguineus.
