Shock Pulse Index and Its Application in the Fault Diagnosis of Rolling Element Bearings
Authors: Sun Peng , Liao Yuhe , Lin Jing
Published: January 2017

Properties of time domain parameters of the vibration signal have been extensively studied for the fault diagnosis of rolling element bearings (REB). Parameters like kurtosis and Envelope Harmonic-to-Noise Ratio are most widely applied in this field and some important progress has been made. However, since only one-sided information is contained in these parameters respectively, problems still exist in practice when the signals collected are of complicated structure and/or contaminated by strong background noises. A new parameter, named Shock pulse index (SPI), is proposed in this paper. It integrates the mutual advantage of both parameters above and can help effectively identify fault related impulse components under the interference of strong background noises, unrelated harmonic components and random impulses. The SPI optimizes the parameters of Maximum Correlated Kurtosis Deconvolution (MCKD), which is used to filter the signals under consideration. Finally, the interested transient information contained in the filtered signal can be highlighted through demodulation with Teager Energy Operator (TEO). Fault related impulse components can therefore be extracted accurately. Simulations and experiment analyses verify the effectiveness and correctness of the SPI.

Ammonia Concentrations and Emissions from Finishing Pigs Reared in Different Growing Rooms
Authors: Costa Annamaria
Published: January 2017

Even with the adoption of Best Available Techniques (BAT) standards, pig producers have observed different degrees of fouling on the floor during the finishing phase. These differences depend on the excretory behavior of pigs reared in different growing facilities. Our objectives in this study were to measure ammonia (NH3) concentrations and emissions from finishing pigs reared in different growing rooms and subsequently housed in identical BAT room types. The 1600 pigs used in the study were reared in growing rooms with a slatted floor and a vacuum system for manure removal (WSF) or in growing rooms with a solid floor and an outside alley and storage pit (WCF). Pigs were grouped by type of growing room and allocated to two WCF finishing rooms per group. Mean NH3concentration (7.45 vs. 5.31 mg m−3) and degree of fouling on the floor (77 vs. 37%) were significantly greater (P< 0.001) in the WSF compared with the WCF finishing rooms. Pigs in the WCF emitted 4.63 g NH3pig−1during the measurement period, whereas those in the WSF emitted 6.55 g NH3pig−1. Our results indicate that, because pigs’ fouling behavior is established during the growing phase, the finishing phase should be performed in a similar facility designed to maintain the NH3reduction provided by BAT systems. In this study, growers housed in a WSF facility exhibited the same defecating and urinating habits when moved to the WCF facility despite the availability of an outside alley. This management choice limited the capability to lower NH3concentrations and emissions, negatively affecting animal performance.

Core Ideas

Two groups of 800 fattening pigs were housed in different BAT weaning facilities.

Weaners were reared either on slats or on full floor with external area.

Floors were fouled by 35% in WCF and by 70% in WSF weaning rooms.

With fatteners reared in WCF houses, fouling degree was 37% (WCF) and 77% (WSF).

Ammonia concentration and emission was higher for WSF fatteners.
Chemical Composition of Soil Organic Matter in a Subarctic Peatland: Influence of Shifting Vegetation Communities

Core Ideas

Soil organic matter chemical composition highlighted the inputs of varied vegetation communities in the past.

Soil N is an indicator of peat decomposition based on relationship of functional group C and total N.

Future surveys of soil organic matter biogeochemical parameters and C chemical composition should be pursued.

Climate change in the subarctic region has increased the rate of inundation of peatlands due to increased temperatures, precipitation, and permafrost thaw. Increased inundation may result in vegetation community shifts, as documented in a subarctic mire near Abisko, Sweden. The wet fen communities have established in former sphagnum areas, and sphagnum colonized in degraded palsa hummocks. At Stordalen mire, we studied the influence of vegetation community on chemical composition of peat soil organic matter (SOM). Vegetation and soil samples were obtained along a hydrologic gradient with representative communities: palsa, sphagnum, and fen. Soil organic matter chemical composition indicated shifts in vegetative communities. Total N and N isotope signatures in fen soils showed characteristics of sphagnum and palsa communities at >6‐cm depth, and sphagnum soil profile signatures shifted from sphagnum to palsa properties at a 20‐cm depth. Soil chemical composition measured by Fourier Transform Infrared (FTIR) spectroscopy and13C Nuclear Magnetic Resonance (NMR) spectroscopy showed increasing recalcitrant C (alkyl and aromatic) in palsa soil. Sphagnum soil profiles sustained labile organic C (O‐alkyl) until 15 cm then shifted to humified soil, and fen soil profiles showed areas of sphagnum and palsa signatures. Furthermore, the strong relationship between functional group C (O‐alkyl and alkyl) and total N demonstrated that soil N is an effective indicator of peat decomposition. Our results identified change points in soil chemical composition in regards to N content and C functional group which highlights the importance of historic vegetation community on chemical composition of peat soils.

Published: January 2017

Myracrodruon urundeuva (Allemão) Engl. é uma espécie pertencente à Família Anacardiaceae, conhecida e utilizada no Domínio da Caatinga, no semiárido nordestino. Com isto, realizou um estudo na Comunidade Rural Peba dos Vicentes, no Município de São José de Piranhas (Paraíba, Brasil), com o objetivo de registrar o uso da espécie por meio de entrevistas semiestruturadas com os chefes de famílias (seis homens e seis mulheres), sendo os usos classificados como madeireiros e não madeireiros, e também se registrou as categorias onde tais usos se enquadram. Além das informações sobre o uso, o presente estudo realizou um levantamento da disponibilidade local, por meio de uma turnê guiada com duração de 24 h, onde cada indivíduo encontrado teve seu perímetro (cm) e altura (m) registrados com auxílio de uma fita métrica e georreferenciados com um GPS. Foram registradas 107 citações de uso, sendo 49 por mulheres e 58 por homens, com 64 e 43 citações de uso madeireiro e não madeireiro, respectivamente. A categoria que recebeu o maior número de citações foi construção, medicinal e tecnologia. Na turnê guiada foram encontrados 207 indivíduos, destes 98 estavam em áreas antropizadas, 2 nas margens de estrada, 57 nas margens de rios (mata ciliar) e 50 em áreas de vegetação nativa. Os usos madeireiros têm ameaçado as populações de M. urundeuva no Nordeste brasileiro, podendo contribuir para sua extinção. Os resultados obtidos evidenciam que M. urundeuva apresentou muitos indivíduos na vegetação local, porém nenhum dos indivíduos encontrados apresentou retirada de casca. Mediante tal fato, sugere-se que sejam realizados estudos de monitoramento a respeito da espécie, com atividades voltadas para a conservação e manejo sustentável.

Published: January 2017

A discussão acerca da destinação final incorreta dos resíduos sólidos move a busca por novas tecnologias no Brasil. Uma forma de tratamento extremamente eficiente e bastante polêmica para estes resíduos é a incineração, não descartando a necessidade de políticas públicas que abordem a educação ambiental no país, principalmente na base escolar, para que haja um entendimento por parte da população sobre a importância da redução, da reciclagem, da reutilização e da destinação final correta dos resíduos sólidos. A proposta do projeto de iniciação científica foi produzir energia elétrica a partir da queima de resíduos sólidos domésticos, utilizando um motor tipo Stirling construído com materiais reaproveitados. O país que serviu de inspiração para a realização deste projeto foi a Alemanha, que incinera 40% dos seus resíduos e faz o reaproveitamento energético eficiente. Durante a execução do projeto surgiu a oportunidade de uma das participantes conhecer esta tecnologia de perto, através de um intercâmbio. Em síntese o presente artigo contempla a experiência do intercâmbio realizado, bem como o alcance dos objetivos propostos no projeto de iniciação científica. Foram construídos um incinerador e um motor termodinâmico, que gerou energia suficiente para acender uma lâmpada de led de 10 W a partir da combustão dos resíduos selecionados para o processo.

Published: January 2017

Green leafy vegetables are important component of human diets, providing fibre, minerals and vitamins. Recently, non-conventional food plants are incorporated in diet to provide not only nutrient but also traditional treatment for various ailments. In a way to combat the devastating effect of malnutrition, there should be a long term intervention such as dietary diversification which can be achieved by increasing the production of locally produced foods and non-conventional vegetables. This study analysed the nutritional composition and anti-oxidant potential of Heliotropium indicum L. (Lamiales: Boraginaceae). The proximate analyses were carried out using the methods described by the Association of Official Analytical Chemist (AOAC). Vitamins were quantified by high performance liquid chromatography (HPLC). Mineral content were determined by Atomic Absorption Spectrophotometric (AAS) technique. The anti-oxidant activity was tested spectrophotometrically using ascorbic and gallic acid as standards. The nutrient constituents revealed that the fat content ranged between 0.67% +/- 0.05% and ash content ranged between 15.7% +/- 0.04%. Varying levels of vitamins like ascorbic acid, retinol, tocopherols, riboflavin, thiamine and niacin was quantified in the samples. Ascorbic acid content ranged between 622.6 mg/100 g. The aqueous extracts of the samples significantly (P < 0.05) inhibited DPPH radical with an IC50 value of 38 ug/mL. It is evident from this study that these indigenous leafy vegetable which are not widely known and consumed are of high nutritional quality and anti-oxidant potential. This vegetable can contribute significantly to the nutrient requirement of man and could complement the conventional ones in enhancing food security and sustainable livelihood. Hence, their cultivation and consumption should be encouraged.
Gas chromatographic and antimicrobial analyses of phenolic compounds in Senna alata (L.) Roxb. (Fabales: Fabaceae)
Authors: Adelowo Funmilayo , Oladeji Oluwole
Published: January 2017

This present work is aimed at determining the chemical components in Senna alata (L.) Roxb. (Fabales: Fabaceae), that contains a large array of phenolic compounds which make it useful as antifungal and antibacterial. Despite a notable success in the recent researches, yet, the quantification of the chemical components has not been actually specified. There is a claim by local people that S. alata can cure fungi and bacteria related diseases. Therefore, there is a need to ascertain this claim by examining the bioactive components present in the plant. The Gas Chromatography (GC) analysis was performed using a Clarus 500 Perkin Elmer gas chromatography equipped with an Elite-5 capillary column with the addition of an absolute alcohol. The antimicrobial analysis was carried out using Agar Disc Diffusion Method. In the GC chromatogram, four prominent peaks were observed in leaf chromatogram, three peaks in flower chromatogram and five peaks in fruit chromatogram, respectively. The flower contained the highest amount of cinnamic acid (52.91%) and the fruit contained the least (17.03%). The presence of some bioactive metabolites could be responsible for the observed antifungal and antibacterial activities on the susceptible organisms studied. It could be concluded that this plant is natural sources of antimicrobial substances of high importance and are useful in chemotherapy.

Authors: Souza Tamires Aparecida Ferreira
Published: January 2017

Com o desenvolvimento do regionalismo, a presença de ameaças transnacionais, além de problemas e soluções estrategicamente sensíveis às constituições históricas, nasce a necessidade de uma cooperação que una os países de uma determinada região. Nota-se um movimento de medidas interestatais, em que os Estados desejam consolidar novas vias para o progresso cooperativo no campo da defesa, como através do Conselho de Defesa Sul-Americano (CDS), da União de Nações Sul-Americanas. A proposta de formação do primeiro conselho sub-regional de defesa da América do Sul fez-se a partir da justificativa de enriquecimento dos mecanismos de cooperação militar e extensão do nível de confiança mútua a toda à região. O presente artigo objetiva analisar o CDS por meio de seus fatores sistêmicos, institucionais e operacionais. Para tanto, será utilizada a técnica de entrevista, realizada com autoridades e representantes do Conselho, na Argentina e no Brasil. Verificou-se com a pesquisa que o CDS conta com significativos avanços no campo de medidas de confiança e de indústria e tecnologia de defesa, bem como na construção de estruturas permanentes do órgão. Contudo, o Conselho encontra-se em fase de aprimoramento, apresentando dificuldades em relação a consensos e transparência, não compondo ainda uma voz sul-americana única em defesa.
Rumo à cooperação e ao desenvolvimento: as políticas brasileiras para a faixa de fronteira
Authors: Scherma Marcio
Published: January 2017

O artigo analisa as políticas federais para a “faixa de fronteira” brasileira, indicando continuidades e mudanças. Utilizou-se a revisão bibliográfica e a análise documental para testar a hipótese de que a partir da redemocratização há uma ruptura com o padrão anterior de atuação nas fronteiras. Vale dizer, tanto na doutrina como na ação, predominava a segurança como o foco nacional para a região. Já a partir dos anos 80, o foco de atuação seria alterado e passaria a estar no potencial de integração das fronteiras e no fomento ao seu desenvolvimento socioeconômico. A hipótese foi confirmada parcialmente. Detectou-se uma transição entre estas visões que, porém, não coincide cronologicamente com a redemocratização, embora ganhe intensidade a partir dela. Salienta-se que atualmente ambas visões coexistem e disputam espaços institucionais, políticas e recursos. Espera-se que o artigo contribua para elucidar aspectos sobre a região, as políticas a ela destinadas e a integração regional.

Published: January 2017

The aim of the present work was to evaluate the effects of carbon sources and chemical oxygen demand (COD)/NO2−-N ratios on the anammox–denitrification coupling process of the simultaneous partial nitrification, anammox and denitrification (SNAD) biofilm. Also, the anammox activities of the SNAD biofilm were investigated under different temperature. Kaldnes rings taken from the SNAD biofilm reactor were operated in batch tests to determine the nitrogen removal rates. As a result, with the carbon source of sodium acetate, the appropriate COD/NO2−-N ratios for the anammox–denitrification coupling process were 1 and 2. With the COD/NO2−-N ratios of 1, 2, 3, 4 and 5, the corresponding NO2−-N consumption via anammox was 87.1%, 52.2%, 29.3%, 23.7% and 16.3%, respectively. However, with the carbon source of sodium propionate and glucose, the anammox bacteria was found to perform higher nitrite competitive ability than denitrifiers at the COD/NO2−-N ratio of 5. Also, the SNAD biofilm could perform anammox activity at 15 °C with the nitrogen removal rate of 0.071 kg total inorganic nitrogen per kg volatile suspended solids per day. These results indicated that the SNAD biofilm process might be feasible for the treatment of municipal wastewater at normal temperature.
Release of hydrogen sulfide in a sewer system under intermittent flow conditions: the Ericeira case study, in Portugal
Authors: Matias Natércia , Matos Rita Ventura , Ferreira Filipa , Vollertsen Jes , Matos José Saldanha
Published: January 2017

The presence and fate of hydrogen sulfide in wastewater systems were studied in two stretches of an intercepting sewer system located in a coastal village, in Portugal. A range of hydraulic parameters were obtained and liquid and gas phase measurements were carried out, both continuously and through intensive sampling campaigns. Upstream, where flow rates were relatively low, dissolved sulfide concentrations around 12 mg S L−1 and hydrogen sulfide gas concentrations above 250 ppm were observed, along with limited corrosion damage. It is believed this is due to the low relative humidity detected along the atmosphere of the studied sewer system. Downstream, gas concentrations were always below 40 ppm. Despite that, high signs of corrosion were detected, particularly in manholes with drop structures. It is thought that condensation of spray produced by the fall is the main cause of the phenomenon. Another relevant observation was the rapid decline in dissolved sulfide contents along gravity trunk sewers following the discharge of rising mains, with loss rates as high as 40 mg S L−1 h−1. Air-flow velocities corresponded to 15–50% of wastewater flows, an observation which agrees with other authors' publications addressing relatively small pipes and moderate water flows.

Authors: Babaei Ali Akbar , Ghanbari Farshid , Yengejeh Reza Jalilzadeh
Published: January 2017

Photoelectro-Fenton (PEF) was carried out for concurrent removals of inorganic and organic pollutants with simultaneous applications of two different anodes (iron and copper). Cadmium and Direct Orange 26 (DO26) were selected as samples of the contaminants of textile wastewater and influential parameters (pH, current density, H2O2 dosage and electrolysis time) of PEF were evaluated on Cd and DO26 removals. Both mechanisms of coagulation and oxidation affected the removal of both pollutants. Optimal conditions were achieved with pH = 4.0, current density of 5 mA/cm2, 3 mM H2O2 and 40 min electrolysis time, and under these conditions, the dye was completely removed and the Cd removal efficiency was about 80%. Unlike H2O2, persulfate had no scavenging effect in high dosages. The effects of different anions and two matrixes (tap water and wastewater) on Cd and dye removals were investigated. The results showed that decolorization was reduced by the phosphate and nitrate ions while chloride ion accelerated the decolorization rate. In terms of Cd removal, no significant change was observed in the presence of the anions except for phosphate ion. The sludge of PEF was assessed by Fourier transform infrared, field emission scanning electron microscope and energy-dispersive X-ray spectroscopy.
