title: Survey of Phaeomoniella chlamydospora in vineyard weeds

description: ABSTRACT Petri disease is serious, complex and difficult to control in vines worldwide. The main causal agent of this disease is the fungus Phaeomoniella chlamydospora. This fungus also occurs in the vineyard weed Convolvulus arvensis. In Brazil, this fungus was found only in grapevines. Thus, the aim of the present study was to carry out a phytosociological survey of weeds in an area with different vine rootstocks, as well as in a field of seedlings production, in an experimental area with vines and in different areas with commercial vineyards, besides verifying which weed species could be hosting the fungus P. chlamydospora. For the phytosociological survey of weeds, a square was randomly cast ten times at the site, followed by counting, identification and sampling of all species. To verify host species of the fungus, vascular tissue of plants was isolated in culture media and DNA extraction from the same plant tissue was carried out followed by PCR with specific primers of the fungus for the elongation factor gene (Pchlamy-EF-F 5’-CTCATTATCACATTTTGCTGC-3’ and Pchlamy-EF-R 5’-GAGAACAGTCAGTGATGAGC-3’). Considering all surveyed fields, 46 weed species were detected in 17 families, especially Asteraceae and Poaceae, which had the largest number of species. Using conventional or molecular methods, the fungus P. chlamydospora was not detected infecting weeds, which highlights that Petri disease occurs only in grapevines.

title: Monitoring vegetation coverage in Tongren from 2000 to 2016 based on Landsat7 ETM+ and Landsat8

description: Abstract Vegetation coverage is an important indicator in regional ecological environment monitoring and plays a key role in its quality assessment. We consider Landsat7 ETM+ in 2000 and Landsat8 in 2016 as data sources using a different time phase partial image substitution method to eliminate cloud effects and an NDVI dimidiate pixel model to invert the vegetation coverage of the two time phases. We further classify them into five grades, provide statistics and analyse the areas of different grades at different time periods, while monitoring the spatial evolution of vegetation coverage over the past 16 years in Tongren. Experimental results showed that: (1) the different time phase partial image substitution method could reduce the influence of clouds on vegetation extraction; (2) in Tongren, the vegetation coverage area was decreased from 17,300.1 km2 to 17,224.8 km2 (i.e. decreased by 75.3 km2); (3) the areas of grade I and V increased by 0.42% and 15.08%, respectively, whereas the areas of grade II, III and IV decreased by 3.15%, 6.98% and 5.37%, respectively, which indicates that most of the area containing lower amount of vegetation gradually altered into an area containing a higher coverage of vegetation, whereas a few areas became bare land; and (4) the vegetation areas decreased due to expansion of cities and construction of dams, while vegetation increased due to the cultivation of crops and trees. Research shows that the overall evolution of vegetation coverage in Tongren is considerably good. However, while undertaking future development in the mountainous Karst region, one should be aware of the land’s intensive use and environmental protection.

title: Cardiovascular adverse events associated with oral antineoplastic therapy

description: ABSTRACT Objective: To identify in the literature the cardiovascular adverse events resulting from oral antineoplastic therapy. Method: Integrative review of the literature through the SCOPUS, Scientific Electronic Library Online (SciELO), Cumulative Index to Nursing and Allied Health Literature (CINAHL), Medical Literature Analysis and Retrieval System Online (MEDLINE) databases. The antineoplastic, cardiotoxicity, cardiovascular system and adverse reaction descriptors were used in Portuguese, English and Spanish. We selected 23 articles published between 1985 and 2015. Results: Twenty studies were related to cardiac events and eleven to peripheral vascular events. The most frequent adverse cardiac events were reduced left ventricular ejection fraction, myocardial infarction, changes in the electrocardiogram, heart failure and angina, whereas peripheral vascular events were hypertension and thromboembolism. Conclusion: Oral antineoplastic therapy is associated with different adverse events, including cardiac and peripheral vascular events.

title: Preparation and characterization of composites from copolymer styrene-butadiene and chicken feathers

description: Abstract Over five million tons of chicken feathers (CF) are generated all over the world by the poultry industry, with an immense potential to exploit. Keratin is an abundant protein found in chicken feathers that offers excellent thermal properties and it is durable, insoluble in organic solvents and chemically unreactive. Elastomers are materials with a wide application range, for instance, adhesives, shoe soles, plastic modifiers, tire industry, sealants, among others. However, it is necessary to improve their properties and mechanical performance at elevated temperatures. A good path to do so is to combine the elastomer with CF to obtain materials with enhanced properties. In present work, a composite based on styrene-butadiene (SB) elastomer and CF was prepared by means of melt mixing. Composites were characterized by FTIR, DSC, DMA and X ray diffraction techniques. The results show that there is an increase in stiffness of SB/CF composites compared with pure elastomer.

title: Haematological and Serum Biochemical Responses of Ovambo Chickens Fed Provitamin A Biofortified Maize

description: ABSTRACT The current study was conducted to investigate the influence of provitamin A biofortified maize (PABM) diet, sex and age of birds on the haematological and serum biochemistry parameters of indigenous chickens. A total of ninety-six 13 week old male and female Ovambo chickens were reared and fed on either white maize (WM) a low vitamin A diet or a PABM based diet for eight weeks. Each diet was replicated four times. Packed cell volume (PCV), haemoglobin (Hb), erythrocyte concentration (RBC), leucocytes concentration (WBC), mean corpuscular volume (MCV), mean corpuscular haemoglobin (MCH) and mean corpuscular haemoglobin concentration (MCHC) were measured. Albumin (ALB), globulin (GLOB), total proteins (TP), triglycerides (TRI), cholesterol (CHOLES), uric acid (UA) and creatinine (CREAT) concentrations were assessed. The activity of alanine transaminase (ALT) alkaline phosphate (ALP) and aspartate transaminanse (AST) were also assayed. The PABM diet increased (p&lt;0.05) PCV and WBC of female birds. All mean values for the haematological parameters regardless of the age, sex and diets were within the normal range. Age had an effect (p&lt;0.05) on ALT, TP, GLOB, TRI and UA. Sex of the birds significantly influenced the TP, GLOB, ALB, CREAT and TRI levels. There was significant interaction of diet and age of bird on ALP, ALT, and GLOB concentrations. The cholesterol level in 18 weeks old male birds fed on the WM diet was above the normal range. In conclusion, feeding PABM diet to female and male indigenous chickens will not negatively impact on the health status of indigenous chickens.

title: Shelf life of artisanal demi-glace sauce

description: Abstract The objective of this study was to elaborate and evaluate the shelf life of the liquid artisanal demi-glace sauce considering sensory, microbiological and lipid oxidation characteristics during 75 days of storage compared to commercial hydrated demi-glace sauce. Sensory aspects (visual and olfactory), counts of coliform and Staphylococcus aureus, determination of Salmonella sp. and lipid oxidation were evaluated every 15 days. The artisanal demi-glace sauce was homogenous, without sensory alteration during the storage period, with olfactory alteration only at the end. The commercial demi-glace sauce remained unchanged until t3 (30 days), from t4 (45 days) presented turbid appearance, followed by phase separation and with unpleasant odor in t6 (75 days). The lipid oxidation showed an increased concentration of malonaldehyde at every evaluated time. The artisanal and commercial demi-glace sauces showed a significant difference at t1, t2, t4 and t5, when the artisanal sauce had lower contents of malonaldehyde (18, 23, 36 and 11%, respectively), only at the 30th and 75th days of storage there was significant similarity. The sauces were within the microbiological standards required by the law. Although the artisanal demi-glace sauce does not contain conservatives, its shelf life was similar to the hydrated commercial product.

title: ACID MINE DRAINAGE TREATMENT AND METAL REMOVAL BASED ON A BIOLOGICAL SULFATE-REDUCING PROCESS

description: ABSTRACT The key purpose of this research was to explore the capacity of an anaerobic stirred batch reactor (ASBR) to deal with acid mine drainage (AMD) based on the activity of sulfate reducing bacteria (SRB). The tests showed that SRB produced hydrogen sulfide that precipitated the metals Fe2+, Zn2+, and Cu2+. Ethanol was used as both the only source of carbon and electron donor. Throughout the experiment, the ratio of chemical oxygen demand (COD) to sulfate was constant at 1.0. The reactor was operated for 218 days using synthetic AMD at pH 4.0 containing 1000 and 1500 mg·L-1of sulfate,100 mg·L-1of Fe2+, 20 mg·L-1Zn2+, and 5 mg·L-1Cu2+. The metal removal rates were greater than 99% with effluent pH of 6.5 to 7.4. The sulfide concentration reached 56.6 mg·L-1 and sulfate removal was 43 to 65%.

title: Atlas.ti software as a resource for content analysis: analyzing robotics in science teaching in Brazilian theses

description: Abstract: This paper presents the use of the Atlas.ti software as a resource to the realization of the Bardin’s Content Analysis. For this, we use as a methodological framework the systematic review of the Brazilian doctoral theses that study the use of educational robotics in science education. We describe, from the data collected in the Digital Library of Thesis and Dissertations, the commands in the software to conduct the steps of pre-analysis, material exploration and inferences. With this, was possible to identify trends and gaps in Brazilian research at the doctoral level on the thematic focus, which were discussed in the four empirical categories of analysis: Epistemological basis, Methodological inconsistency, Target audience and Characteristics of national production. After the inferences, it was possible to understand the scope of the Brazilian theses. As well, we concluded that the software is a satisfactory technological resource to carry out all the steps of Content Analysis.

title: Seroprevalence and risk factors associated with canine visceral leishmaniasis in the State of Paraíba, Brazil

description: Abstract INTRODUCTION: The aim of this study was to determine the seroprevalence and risk factors associated with canine visceral leishmaniasis in Paraíba State. METHODS: Blood samples were collected from 411 dogs in four municipalities of Paraíba State. The seroprevalence was assessed by using ELISA. RESULTS: The seroprevalence ranged from 7.2% to 20%. The risk factors that were associated with the disease were the presence of ticks and contact with other animals. CONCLUSIONS: The seroprevalence of canine visceral leishmaniasis is high in Paraíba, indicating the need for health authorities to resume visceral leishmaniasis control activities. The ruralization of suburban areas in the region tends to homogenize the risk factors between suburban and rural areas.
