Desempenho de tractores florestais processadores

A time-and-motion study in wood processing of the Eucalyptus harvester's operational cycle was developed. The objective was to evaluate wood harvesters working under several site conditions. The research includes two kinds of harvesters while processing wood to supply paper and cellulose factories, as follows: a machine with twin tires and other one with large tracks, both connected to a different head harvester models. The forestry species were Eucalyptus saligna Smith and Eucalyptus grandis Hill ex Maiden, seven and eight years old, in slope terrains ranging from 0% to 10% degrees, under harvesting systems used by Votorantim and Suzano forestry companies, in São Paulo State, Brazi. Considering all field research, results disclosed that, for some conditions, both machines have shown mathematical correlation between some mechanical wood operation within the processing operational cycle and the saw logs production. All the mathematical correlations were found to express logarithmical models.

Rainwater chemical composition and annual atmosphere depositon in Sorocaba (SP)

This work evaluated the rainwater chemical composition and the annual atmospheric deposition in Sorocaba, (Sao Paulo State), Brazil. One sampling ˜ point was chosen and forty samples were collected between January and December 2006. The analyses were performed for pH, electrical conductivity, sodium, calcium, potassium, magnesium, sulphate, nitrate, phosphate, alkalinity and chloride. The rainwater pH varied from 5.20 to 6.40, being Ca2+ the main ion responsible for controlling the rainwater pH. The ionic concentration decreases in the following order: Ca2+>Na+> K+>Mg2+ for cations and SO2− 4 >HCO− 3 >NO− 3 >Cl−>PO3− 4 for anions. The annual atmospheric deposition appears to be controlled by the following sources: mining activities and cement factories (Ca2+ and HCO− 3 ), agricultural activities (K+, NO− 3 and PO3− 4 ), soil dust (Na+, Mg2+ and HCO− 3 ) and fossil fuel burning (SO2− 4 )

Parque da Sanbra: requalificando um vazio urbano em Ourinhos

This work consists in analyzing an urban area of the city of Ourinhos. That site was located an old industry, the 40s, the Brazilian Northeast Algodoeira Society (Sanbra). Which was shut down and the existing buildings were demolished. With the demolition, was an area unused to city, and became an urban empty in the railway area of Ourinhos. The local study is an example of what happened in many Brazilian cities, where old factories were closed, making it useless to the city and also without identity with the urban space. Therefore, this project sought the potentialities and problematics of the area and its surroundings, for the purpose to get elements to create a quality space for the life of ourinhenses and give a new use to space

Indústria frigorífica halal no Brasil, mão-de-obra islamita e estado de exceção

In the last decade, Brazilian meat export rates for Muslim religious countries have increased, and also has the immigration of Africans workers able to perform the slaughter following the precepts of Islam - religion that has expanded in the world, and thus, has the halal food segment. Halal, the Islamic ideology, means lawful, authorized by God: are those products that Allah in the Holy Qur'an releases for human consumption. To get halal certification some measures during slaughter/processing food should be taken. In the case of the slaughterhouses the animal must be slaughtered by a Muslim. Consequently, the demand for this skilled labor makes many African-Muslims get jobs in factories owned by BRF Foods, JBS and Marfrig; refugees and with their citizenship rights committed, these individuals live in a socio-political state of exception and overexploitation. In this study we intend to discuss the object of study Islamist workforce in Brazilian halal meat industry using the theoretical reflections of Giorgio Agamben (Homo Sacer in 2002, and State of Exception, 2004) and David Harvey (The Condition of Postmodernity, 2008, and The New Imperialism, 2004) to address the situation of immigrants in the meat business in Brazil, specially those on the halal certification segment, whose working and living conditions were described from academic studies and primary sources (articles in newspapers / magazines, websites, immigration official data). In addition we use the works of Rogério Heasbaert (O mito da desterritorialização, 2007) and Robert Kurz (Os paradoxos dos direitos humanos: inclusão e exclusão na modernidade, 2003) to discuss human mobility in this new century

The white epidemic and the asepsis of refined earthenware in Belle Epoque Sao Paulo

The article examines Brazilian refined earthenwares known as faianca fina (fine faience) and relates ideas about its production to the contextual backdrop of hygienist discourses in the city of Sao Paulo in the early twentieth century. Based on an analysis of glaze components, moisture expansion processes, and technological aspects of the production of earthenware recovered from the Petybon archeological site, it is suggested that the establishment of factories and the production and consumption of white ceramics in the city of Sao Paulo were partially a consequence of the vigorous hygienization policies and modernity projects then advocated by Sao Paulo's elites.

Environmental management in ethanol and sugarcane plants in Brazil

There has been much discussion on the importance of Brazilian ethanol in promoting a more sustainable society. However, there is a lack of analysis of whether sugarcane plants/factories that produce this ethanol are environmentally suitable. Thus, the objective of this study was to analyse stages of environmental management at four Brazilian ethanol-producing plants, examining the management practices adopted and the factors behind this adoption. The results indicate that (1) only one of the four plants is in the environmentally proactive stage; (2) all plants are adopting operational and organisational environmental management practices; (3) all plants have problems in communicating environmental management practices; and (4) the plant with the most advanced environmental management makes intense use of communication practices and is strongly oriented towards a more environmentally aware international market. This paper is an attempt to explain the complex relationship between the evolution of environmental management, environmental practices and motivation using a framework. The implications for society, plant directors and scholars are described, as well as the study's limitations.

1(--) and 0(++) heavy four-quark and molecule states in QCD

We estimate the masses of the 1(--) heavy four-quark and molecule states by combining exponential Laplace (LSR) and finite energy (FESR) sum rules known perturbatively to lowest order (LO) in alpha(s) but including non-perturbative terms up to the complete dimension-six condensate contributions. This approach allows to fix more precisely the value of the QCD continuum threshold (often taken ad hoc) at which the optimal result is extracted. We use double ratio of sum rules (DRSR) for determining the SU(3) breakings terms. We also study the effects of the heavy quark mass definitions on these LO results. The SU(3) mass-splittings of about (50-110) MeV and the ones of about (250-300) MeV between the lowest ground states and their 1st radial excitations are (almost) heavy-flavor independent. The mass predictions summarized in Table 4 are compared with the ones in the literature (when available) and with the three Y-c(4260, 4360, 4660) and Y-b(10890) 1(--) experimental candidates. We conclude (to this order approximation) that the lowest observed state cannot be a pure 1(--) four-quark nor a pure molecule but may result from their mixings. We extend the above analyzes to the 0(++) four-quark and molecule states which are about (0.5-1) GeV heavier than the corresponding 1(--) states, while the splittings between the 0(++) lowest ground state and the 1st radial excitation is about (300-500) MeV. We complete the analysis by estimating the decay constants of the 1(--) and 0(++) four-quark states which are tiny and which exhibit a 1/M-Q behavior. Our predictions can be further tested using some alternative non-perturbative approaches or/and at LHCb and some other hadron factories. (c) 2012 Elsevier B.V. All rights reserved.

Evidence for glycosylation on a DNA-binding protein of Salmonella enterica

Abstract Background All organisms living under aerobic atmosphere have powerful mechanisms that confer their macromolecules protection against oxygen reactive species. Microorganisms have developed biomolecule-protecting systems in response to starvation and/or oxidative stress, such as DNA biocrystallization with Dps (DNA-binding protein from starved cells). Dps is a protein that is produced in large amounts when the bacterial cell faces harm, which results in DNA protection. In this work, we evaluated the glycosylation in the Dps extracted from Salmonella enterica serovar Typhimurium. This Dps was purified from the crude extract as an 18-kDa protein, by means of affinity chromatography on an immobilized jacalin column. Results The N-terminal sequencing of the jacalin-bound protein revealed 100% identity with the Dps of S. enterica serovar Typhimurium. Methyl-alpha-galactopyranoside inhibited the binding of Dps to jacalin in an enzyme-linked lectin assay, suggesting that the carbohydrate recognition domain (CRD) of jacalin is involved in the interaction with Dps. Furthermore, monosaccharide compositional analysis showed that Dps contained mannose, glucose, and an unknown sugar residue. Finally, jacalin-binding Dps was detected in larger amounts during the bacterial earlier growth periods, whereas high detection of total Dps was verified throughout the bacterial growth period. Conclusion Taken together, these results indicate that Dps undergoes post-translational modifications in the pre- and early stationary phases of bacterial growth. There is also evidence that a small mannose-containing oligosaccharide is linked to this bacterial protein.
