Abstract Background Foot-and-mouth disease (FMD) is an economically important and highly contagious viral disease that affects cloven-hoofed domestic and wild animals. Virus isolation and enzyme-linked immunosorbent assay (ELISA) are the gold standard tests for diagnosis of FMD. As these methods are time consuming, assays based on viral nucleic acid amplification have been developed. Results A previously described real-time reverse transcriptase polymerase chain reaction (RT-PCR) assay with high sensitivity ...

The behavior of arsenic (As) bioleaching from mine tailings containing high amount of As (ca. 34,000 mg/kg) was investigated using Acidithiobacillus thiooxidans to get an insight on the optimal conditions that would be applied to practical heap and/or tank bioleaching tests. Initial pH (1.8–2.2), temperature (25−40 °C), and solid concentration (0.5–4.0%) were employed as experimental parameters. Complementary characterization experiments (e.g., XRD, SEM-EDS, electrophoretic mobility, cell density, and ...

Picobirnavirus (PBV) belongs to the family Picobirnaviridae . Picobirnaviruses contain a bisegmented dsRNA genome that is non-enveloped. A total of 85 pooled faecal samples were collected from the poultry of 37 farms from the Metropolitan Mesoregion of Belém (MMB), Pará state, Brazil. The viral RNA from each sample was analysed by PAGE and reverse transcriptase PCR (RT-PCR). For each county affected, at least one positive sample was selected, cloned and sequenced. The samples showed a positivity of 15. ...

In order to analyze the influence of the contact mechanism in the bioleaching process, bacterial attachment on the Printed Circuit Boards (PCB) surface was avoided using a partition system. The partition system was obtained with a semi-permeable membrane of 12–14 kDa MWCO. A PCB sample of 500–1000 μm particle size was placed inside a partition system for 144 h to compare the copper (Cu) extraction rate by Acidithiobacillus ferrooxidans, with the Cu extraction of a system without partition. The results ...

The mesophilic microbial consortium was composed mainly of L. ferriphilum (90%) and A. caldus (5%). Following an adaptation process of serial sub-culturing, the microbes were capable of tolerating 20 g/L of arsenic. The inoculum used in the CSTR experiment after the adaptation ...

Abstract In this work, we synthesized a series of metal‐substituted potassium heteropolyacid salts and investigated its catalytic activity on oxidation of benzyl alcohol with H 2 O 2 under homogeneous (CH 3 CN) and biphasic (toluene/water) conditions. The Keggin heteropolyacids were converted to lacunar salts (i. e., K 7 PW 11 O 39 ; K 7 PMo 11 O 39 and K 8 SiW 11 O 39 ), which had their vacancies filled with metal cations (i. e., Al 3+ , Fe 3+ , Co 2+ , Cu 2+ , and Ni 2+ ), generating the metal‐substituted salts. ...

Microbial mobilization of arsenopyrite minerals under oxic conditions are well known; however, little is known about how the metals can be mobilized through biodegradation of mine tailings. Therefore, the role of inoculated Acidithiobacillus ferrooxidans on the mobility of arsenic and iron was examined for a sample of South Korean mine tailing. Two modes of interactions (i) direct contact, and (ii) non-contact were examined along with the monitoring of Eh-pH values and cell density. Direct contact ...

• H 3-x Sn x/2 PMo 12 O 40 -catalyzed glycerol etherification was assessed (x = 0.0, 1.0, 2.0, 3.0). • Analyses of TG/DSC, EDS/MEV, BET, DRX characterized Sn(II) heteropoly salts. • NH 3 -TPD and adsorbed pyridine FT-IR showed bifunctional Sn 3/2 PMo 12 O 40 catalyst. • Annual capacity of 30,000 ton 3 with a return on investment (ROI) of 30.7%. In this work, phosphomolybdic acid salts were synthesized exchanging their protons by the Sn(II) cations (i.e., H 3-x Sn x/2 PMo 12 O 40 ; x = 0.0, 1.0, 2.0, 3.0), and evaluated ...

Abstract In this work, aluminum‐exchanged Keggin heteropolyacid salts (i. e., AlPW 12 O 40 , AlPMo 12 O 40 , and Al 4/3 SiW 12 O 40 ) were synthesized and evaluated as catalysts on the camphene oxidation with hydrogen peroxide. The aluminum silicotungstate salt (i. e., Al 4/3 SiW 12 O 40 ) was the most active and selective toward formation of borneol and two novel products; 1‐(3‐(2‐hydroxypropan‐2‐yl) cyclopentyl) ethan‐1‐one, and 3‐(3‐hydroxycyclopentyl)‐3‐methylbutan‐2‐one), which were spectroscopically ...

Resumo Objetivou-se analisar as práticas educativas sobre violência contra a mulher na formação profissional de estudantes universitários. Trata-se de estudo descritivo, exploratório, com abordagem qualitativa, que incluiu oito estudantes universitários de uma instituição pública. Utilizou-se entrevista semiestruturada, e os depoimentos foram gravados e transcritos na íntegra. O tratamento dos dados se deu por meio da análise de conteúdo. A maioria dos acadêmicos afirmou não ter estudado violência ...

Green tea, traditionally used as antidiabetic medicine, positively affects the diabetic nephropathy. It was assumed that these beneficial effects were due to the hypoglycemiant capacity of the tea, wich reduces the glycemic overload and, consequently, the advanced glycation end products rate and oxidative damage. However, these results are still controversial, since tea is not always able to exert a hypoglycemic action, as demonstrated by previous studies. Investigate if green tea infusion can generate ...

The aim of this study was to detect rotavirus F (RVF) and rotavirus G (RVG) in fecal specimens of broiler chickens in Brazil. During 2008 and 2011, a total of 85 fecal samples were collected. The viral genome was extracted, followed by polyacrylamide gel electrophoresis (PAGE), reverse transcription polymerase chain reaction (RT-PCR), and nucleotide sequencing. Samples were screened for rotaviruses by PAGE, and RVF and RVG genome banding patterns were not seen. Using RT-PCR, it was found that 9.4 % (8/ ...
