title: MATURATION STAGES OF FRUITS AND PHYSIOLOGICAL SEED QUALITY OF Physalis ixocarpa BROT. EX HORMEN

description: ABSTRACT Physalis is represented by species that produce fruits with relevant potential for national and international marketing. The species are normally grown from seeds, so maturation studies are important to assist the point of harvest, as well as seeds with a high physiological potential, since the fruits remain enclosed within a cup throughout their development. Despite the nutraceutical importance of fruits and medicinal potential of many species of Physalisinformation on the physiological seeds quality are scarce. This study aimed to monitor the physical and physiological changes of maturation and the viability of seeds during fruit development stages. The fruits of P. ixocarpa were collected in 15, 25, 35, 45, 55 days after anthesis (DAA). Length, diameter, fresh weight, skin and cup coloring characterization, TSS content, number and weight of seeds per fruit were obtained at each development stage. We also evaluated and correlated the coloring and pigment content of the cup (chlorophyll a and b). Water content, dry matter weight and germination rate were measured from fresh and dry seeds (room conditions, 72 hours). The main physical and physiological changes during maturation occurred within 35 DAA. The maximum physiological seeds quality was achieved within 45 DAA when the cup is completely or partially broken with coloring between yellowish-green and light-yellowish-brown and the ripe fruit in dark-green.

title: Prevalence and antibiogram of methicillin resistant Staphylococcus aureus isolated from medical device-related infections; a retrospective study in Lahore, Pakistan

description: Abstract INTRODUCTION: With the advancement of medicine and surgery, various types of medical devices have become part of treatment strategies. METHODS: Identification and antimicrobial sensitivity testing were done according to CLSI guidelines following standard microbiological practices. RESULTS: Urinary catheter infections (31%) were most frequent followed by central venous catheter (18%) and orthopedic implants (15%). Methicillin resistant Staphylococcus aureus (MRSA) was a major cause of device-related infection after Escherichia coli (21%); other pathogens were Klebsiella pneumoniae (14%), Pseudomonas spp. (10%), Acinetobacter spp. (8%) and Candida species (7%). None of MRSA was resistant to vancomycin (MIC ≥16µg/mL). Resistance rates were 98% and 97% for ofloxacin and ciprofloxacin, respectively. CONCLUSIONS Escherichia coli and MRSA are major pathogens of medical device-related infections.

title: Rice Husk Ash as Raw Material for the Synthesis of Silicon and Potassium Slow-Release Fertilizer

description: Rice husk ash (RHA) is a waste material produced in large quantities in many regions worldwide, and its disposal can be problematic. This work describes a method for using RHA to synthesize silicon and potassium slow-release fertilizer. The extraction of silica from RHA was accomplished by alkaline leaching with KOH. Different KOH concentrations and reaction times were evaluated and the best production of K2SiO3 solution was achieved using 6 mol L-1 and 6 h, respectively. The fertilizer was synthesized by the reaction of K2SiO3 with KAlO2 in aqueous medium, followed by calcination at 500 °C. X-ray fluorescence (XRF) and X-ray diffraction (XRD) analyses indicated that the fertilizer composition was similar to mineral kalsilite. Solubility essays indicated lower K+ and Si4+ release percentage in neutral medium. Kinetic mechanisms of release tests can be well explained by the pseudo-second order model. The proposed synthesis seems to be a viable process offering economic and environmental benefits.

title: FRUIT FLIES (DIPTERA: TEPHRITIDAE) AND THEIR PARASITOIDS ASSOCIATED WITH DIFFERENT HOG PLUM GENOTYPES IN TERESINA, PIAUÍ

description: ABSTRACT The aim of this work was to identify and quantify the infestation of fruit fly species and their parasitoids, associated with 20 hog plum genotypes (Spondias mombin L.) in a commercial orchard in Teresina, Piauí, Brazil. The survey was conducted by fruit sampling and monitoring through traps stocked with bait food, in the period from January to December 2012. Overall, 6560 fruits were collected (79.58 kg), resulting in 23059 pupae, of which 10080 fruit flies of the genus Anastrepha and 4984 braconid parasitoids emerged. Anastrepha obliqua species was the predominant with 99.92%. F16P13 and F11P10 genotypes had the highest infestation indexes and F15P11 and F04P01 genotypes, the lowest. The main parasitoids collected were Opius bellus (77.65%), Doryctobracon areolatus (19.88%) and Utetes anastrephae (2.47%). The average parasitism rate among genotypes was of 30.46%. In traps, a total of 1434 fruit flies were collected, whose species were: A. obliqua (97.6%), A. serpentina (1.4%), A. fraterculus (0.4%), A. striata (0.4%), A. dissimilis (0.1%), A. pseudoparallela (0.1%). Anastrepha obliqua species was predominant in the area, based on faunistic analysis. The infestation index in the orchard was relevant for five months (January-May), coinciding with the period of availability of hog plum fruits, reaching the highest peak in March (2.86 FAT). There was a significant negative correlation between number of fruit flies in the orchard and the average air temperature, and a significant positive correlation with rainfall and relative humidity. However, the main factor that influenced the observed infestation index in the hog plum orchard was fruit availability.

title: Klippel-Trenaunay and Parkes-Weber syndromes: two case reports

description: Abstract Parkes-Weber syndrome is a congenital vascular disease that comprises capillary, venous, lymphatic, and arteriovenous malformations. Although Parkes-Weber syndrome is a clinically distinct entity with serious complications, it is still frequently misdiagnosed as Klippel-Trenaunay syndrome, which consists of a triad of malformations involving the capillary, venous, and lymphatic vessels, without arteriovenous fistulas. Both syndromes are generally diagnosed with Doppler ultrasound and confirmed by magnetic resonance angiography. The aim of this study is to describe one case of Klippel-Trenaunay syndrome, in a 36-year-old patient, and one case of Parkes-Weber syndrome, in a 21-year-old patient. We review the literature in order to discuss the possible causes and consequences of these diseases related to venous hypertension and angiodysplasia, taking a clearer approach to their differences, and discussing their treatment.

title: DISEASES INCIDENCE AND FUNGICIDE COST REDUCTION WITH OVERHEAD COVERED GRAPES

description: ABSTRACT An alternative to control diseases on the grapevine is the use of plastic overhead cover. The cost of developing a vineyard is a relevant factor in the use of plastic overhead cover and will be directly linked to the cost of pest control. The aim of this study was to establish criteria for the use of fungicides in vine plants with plastic overhead cover compared to conventional farming in order to reduce the number and cost of application. The experiment was conducted in the 2010/2011 crop year in Viamão - RS, using the Cabernet Sauvignon cultivar grafted on Paulsen 1103 in “Y Shape” trained, with 1.80 x 2.50 m spacing. The following treatments were evaluated: Treatment 1: plastic overhead cover: phytosanitary treatment applied when leaf wetting was observed; Treatment 2: plastic overhead cover: curative treatment, when there were symptoms of disease in shoots; Treatment 3: plastic overhead cover: conventional calendar treatment every 15 days, with reapplication after leaf wetting and Treatment 4: without plastic overhead cover: conventional calendar treatment every 15 days, with reapplication after leaf wetting. The lowest number of applications was observed in treatment where the criteria for fungicide applications was only when symptoms were visualized and the greater number of applications was in the area without plastic overhead cover with conventional treatment, affecting the application cost, but without reflecting in higher productivity. The highest incidence of downy mildew was observed in treatment 4. It was concluded that it is possible to reduce the number of applications and the fungicide cost for disease control using plastic overhead cover. Moreover, this management may provide less contact with chemicals during crop and reduce chemical wastes in the environment and in the harvested product.

title: Analysing Brazilian scientific production on Building Information Modeling

description: Abstract The diffusion of literature on Building Information Modeling (BIM) in Brazil has been growing continuously over the past decade. However, although the literature shows robustness, national scientific production is scarcely monitored. Due to the lack of using development indicators and the fact that there are obstacles in identifying knowledge gaps from previous studies, there are no guidelines that determine new research. In this context, this study aims to analyse the scientific production on BIM in Brazil. This is exploratory research of a bibliographic character, which presents a survey of the Brazilian scientific literature from 2000 to 2015. Using bibliometric and scientometric indicators, the highlighted contributions are (1) the temporal evolution of the bibliographic production, (2) the bibliographic production levels by researchers and production levels of researchers' educational backgrounds by region and institution (3) commonly used keywords and (4) the scientific methods used in dissertations and theses. Thus, the evolution of the scientific production in Brazil is analysed.

title: Employment of Aspergillus niger AN 400 in batch reactors to remove pesticide aqueous matrix

description: ABSTRACT This research proposes the use of the fungus Aspergillus niger AN 400 in treating aqueous matrix containing methyl parathion in batch reactors. The research was divided into two steps. In Step I, were mounted control reactors (RC) containing only methyl parathion in aqueous matrix; reactors with fungus (RF) containing methyl parathion and suspension of fungus spores; and reactors with fungus and ethanol (RFE) containing methyl parathion, the suspension of fungus spores and ethanol. Each reaction time (TR), one RC, one RF and one RFE were put out of operation. The reaction times were studied in 30 days. In Step II, operated a reactor with immobilized biomass (RBI) with methyl parathion and ethanol, making up 5 cycles each lasting one week. As a result, in Step I, it was found that the pH varied from 5 to 8. The final removal of 61% (RF) and 89% (RFE) of COD; 67% (RF) and 52% (RFE) of ammonia nitrogen; 34% (RF) and 45% (RFE) nitrate; 2% (RF) and 15% (RFE) of total phosphorus. In Step II, the pH ranged from 3 to 8 and the average final removal were 94% of filtered COD, 88% gross COD, 19% of ammonia nitrogen, 96% nitrate, 12% of total phosphorus and 95% of methyl parathion with immobilized biomass and 73% with disperse biomass. The results showed that the use of the fungus Aspergillus niger AN 400 can be an alternative for treating wastewater containing methyl parathion.

title: Measurement of Commodity Price Risk: an overview of Brazilian agricultural markets

description: Abstract: This study explores different procedures to estimate price risk in commodity markets. Focusing on Brazilian agricultural markets, the paper proposes to assess both dispersion and downside risk measures using five different approaches (volatility, coefficient of variation, lower partial moments, value at risk and conditional value at risk). Results suggest that some commodities have large price variability but small downside risk, while other commodities show small price variability and large downside risk. Thus, there is no single answer to the question of which commodity exhibits more price risk, but rather distinct answers depending on how risk is perceived by different individuals. These findings are relevant for agents in the agricultural industry as they affect marketing and risk management decisions and for policy makers involved in support programs to agriculture.
