The use of Urban Solid Waste (USW) as sources of energy has acquired rising importance in current discussions of alternative energy supplies, in particular in Brazil. This paper brings to these discussions an examination of the concept of solid wastes, including their historic origins and formation, taking their social, economic and cultural characteristics into account, including point view of waste production liturgy. Consequently, a spendthrift society slanted towards the decreasing marginal utility of assets must make efficient use of its USW in order to reduce excessive output. Besides that, this document presents the Brazilian potential of urban solid waste to produce electric power.

Sugar cane bagasse is one of the largest fuels used for electricity generation in Brazil and its usage has continuously increased to supply the energy demand. This paper presents emission inventory based on power plants burning sugar cane bagasse. The inventory involves the spatial distribution and the estimated flows for the following major pollutants: nitrogen oxides (NOx), particulate material (PM), carbon dioxide (CO2) and total organic carbon (TOC). A total of 384 power plants were inventoried, representing a generated power of 9.9 GW, about 26% of the energy produced by thermal power plants sector. The plants are concentrated in two main poles: one of them in S?o Paulo State and nearby areas and the other one in coast of Brazilian Northeast. The limits proposed by the AP-42 Regulations of the US Environmental Protection Agency (USEPA) for the emission factors were applied. Additional emission factors identified in the scientific literature were also included in the analysis in order to assess the uncertainties associated to the estimative. The estimated emissions showed values in the range 16.0 - 20.5 Gg?year?1 for NOx, 18.0 - 267.0 Gg?year?1 for MP and 20.5 - 26.7 Tg?year?1 for CO2. The contribution of TOC showed a minor contribution around 10 - 20 Mg?year?1. PM showed to be the most representative pollutant emitted by the thermal plants burning sugar cane bagasse, but with a large range of uncertainty. There is a high level of uncertainty associated to the preparation of cane as well as the use of collectors to control particulate emissions. The adequate control over all stages could reduce the bagasse ash content in 90% or more.

We recognize the chemical composition of the acetonic extract of Rhizophora mangle barks(AERM)using mass spectrometry analysis[liquid chromatography(LC)–ESI–IT-MS/MS and matrix-assisted laser desorption/ionization-time of flight-MS(MALDI-TOF)].Analgesic activity was evaluated by formalin and tail-flick experimental ***-inflammatory activity was performed by paw edema test induced by carrageenan and 48/80 *** first series of experiments involved[LC]–FIA–IT-MS/MS with 11 separated catechins derivatives until degree of polymerization 3(DP3).The spectra obtained by MALDI-TOF analysis of the AERM presented two homologous series:one based on polymers of m/z 288 Da increments(up to DP12)and another series based on polymers of m/z[288?162]Da increments(up to DP11).In addition to these series of flavan-3-ol,each DP had a subset of masses with a variation of-16 Da(homologous series of afzelechins-m/z 873–3465 Da)and +16 Da(homologous series of gallocatechins-m/z 905–3497 Da).A similar pattern with homologous series of gallocatechins and afzelechins could also be observed for a fifth and a sixth monohexoside series:glucogallocatechins(m/z 779–3371)and glucoafzelechins(m/z 747–3339).The intraperitoneal administration of different doses of AERM(50,150 and 300 lg mL^(-1))have a morphine-like effect and intense anti-inflammatory activity.

In this paper, we use DEA to measure the NBA basketball teams’ efficiency in seasons 2006-2007, 2007-2008, 2008-2009 and 2009-2010. In this context, each team is a DMU;we select the payroll and the average attendance to be the inputs while the wins and the average points per game to be the outputs. First, in order to obtain benchmarks, we measure the DMUs efficiency through classic DEA BCC model with an assurance region for each one of the four seasons individually and together. When we consider the four seasons together, we may analyse whether the performance of each team increases or decreases over time. Next, we evaluate the teams cross efficiency by DEA game to consider that there is no cooperation among DMUs. This approach also improves the efficiencies discrimination.

Krukenberg tumor is a rare ovarian metastatic cancer from the gastrointestinal tract. It accounts for 1%-5% of malignant tumors of the ovaries, usually being bilateral, of solid consistency and may have cystic areas. The World Health Organization (WHO) defined it as an ovarian metastasis when the mucus-secreting cells of “signet ring” are present, associated with sarcomatous stromal proliferation. We present a 58-year-old woman with the diagnosis of peripheric cholangiocarcinoma with ovarian metastasis, showing history of pain and increased abdominal volume. Magnetic Resonance Imaging (MRI) showed multiple hepatic solid nodules with predominantly peripheral, centripetal and progressive enhancement, demonstrating hipersignal and restriction on diffusion weighted imaging (DWI). In the anexial region, bulky heterogeneous multiloculated cystic formations with solid components, of probable ovarian origin, were noted. Biopsy of the liver nodules confirmed the diagnosis of cholangiocarcinoma.

Clear Cell Sarcoma (CCS) is a rare soft tissue sarcoma that corresponds to a less than 1% of all sarcomas and is a high degree neoplasm with propensity to disseminate to regional lymph nodes. Regional lymphadenectomies have a controversial impact on sarcomas treatment and survival, even though those patients have higher local recurrence and lower survival. So, sentinel lymph node biopsy must be one option for better regional staging to STS with higher propensity to lymph node commitment. The authors demonstrate two cases of CCS submitted to surgery through compartmental resection associated with the sentinel lymph node biopsy. A literature review about soft tissue sarcoma and lymph node sentinel biopsy is shown as an initial experience of two cases.

We present a case of a patient with hypersplenism secondary to portal hypertension due to hepato-splenic schistosomiasis, which was accompanied by severe and refractory thrombocytopenia. We performed spleen ablation and measured the total spleen and ablated volumes with contrast-enhanced computed tomography and volumetry. No major complications occurred, thrombocytopenia was resolved, and platelet levels remained stable, which allowed for early treatment of the patient's underlying disease. Previous work has shown that splenic radiofrequency ablation is an attractive alternative treatment for hypersplenism induced by liver cirrhosis. We aimed to contribute to the currently sparse literature evaluating the role of radiofrequency ablation(RFA) in the management of hypersplenism. We conclude that splenic RFA appears to be a viable and promising option for the treatment of hypersplenism.

Soft tissue sarcomas (STS) are rare neoplasm with frequencies around 1% of all neoplasms. Although it consists of a high heterogeneous group of tumors, surgery is the mean treatment. The STS surgery is still challenging and complex procedure is usually required: this is because STS requires different types of resection and reconstruction due to various tissue-commitments (nerve, arteries, skin and muscle). So, a multidisciplinary team must be prepared for STS approach to obtain the maximum local control and a limited extremity functional impairment. We, here, showing our experience, wish to introduce some technical contrivances in STS surgery, with special reference to tissue reconstruction. This may illustrate the necessity of a multidisciplinary team approach in this surgery.

Specialty rices can present differences in some aspects related to grain pericarp color, shape, size, amylose content or aroma. Most of these rice types are related to cultural traditions and ceremonies, and some of them have also different nutritional value. As a specific market, the economic values of these grains are also higher than common milled rice. Santa Catarina State has the ideal conditions to produce specialty rices. The objective of this work was to develop a rice cultivar with special attributes for the well-appreciated risotto. Two rice lines were combined, evaluated and selected during ten years for characteristics related to Italian food. One line was selected and becomes the new rice variety SCS123 Pérola, developed to attend the economically important specialty rices market of Italian food, specifically the risotto. Experimental tests performed with this variety showed that it can be recommended to all rice-producing regions of Santa Catarina State, Brazil. Cooking tests showed that the grains are appropriated for risotto.

This study aimed to evaluate the external and internal fluxes of nutrients of an urban eutrophic reservoir （lbirit6 reservoir, SE-Brazil）. External loads were estimated in the tributaries （Pintados and Ibirit6 creeks） through nutrient concentrations and discharge measurements. Using Fick＇s law, internal loads were estimated in the reservoir from fluxes across sediment-water interface from nutrient concentration gradients between the pore water and the water. The Ibirit6 creek （urban sewage recipient） contributes with 72%-47% of ammonium （NH4^＋） and 100%-8% of SRP （soluble reactive phosphorus） of the total quantity entering the reservoir, whereas the Pintados creek （oil refinery effluent recipient） contributions are 20%-19% and 44%-100%, respectively. Despite the high external loads （130 and 2.2 ton-yr^-1 of NH4＋ and SRP, respectively）, internal loads （average flux of 120 and 2 mg·cm^-2yr^-1, respectively） correspond to 25% of the total external loads which may sustain a high productivity in the reservoir for a long time even if the external loads are controlled. The stocks of ammonium and SRP of the interstitial water （100 cm of sediment） would be released to the water in six years and five months, respectively, The release time would be extremely larger （〉 3,000 years） considering the stocks of total N and bioavailable P.
