| • The level of antimicrobial resistance in bacteria from organic vs. conventional pigs has been compared for approximate 25 herds of each production system in DK, FR, IT and SE, by sampling faeces at farm or colon content at slaughterhouse from two pigs per herd. • An E. coli isolate was obtained from each sample and subjected to analysis of MIC (minimum inhibitory concentration) values for comparison of the resistance towards 10 antibiotics between production systems. Resistance to ampicillin, streptomycin, sulphonamides, tetracycline and trimethoprim was most common – ranging from 14% to 75% of E. coli isolates from conventional pigs and from 1% to 46% of isolates from organic pigs. The resistance towards these five antibiotics varied markedly between... |

| Information regarding the anatomy of the physiological apical foramen is limited. Knowing its diameter and shapes contributes to clinical work, specifically to the cleaning and shaping of the apical third. The aim of this ex vivo study was to determine the minimum and maximum diameters and shape of the physiological apical foramen in the roots of maxillary and mandibular first molars. A descriptive study was conducted on 89 recently extracted first molars. Roots 3-5 mm from the apex were sectioned and prepared for analysis at 40x magnification. The minimum and maximum diameters of each physiological foramen were measured using the program Motic Images plus 2.0 ML. The shape of the foramina, classified as round, oval or irregular, was determined by the... |

| Patagonia, al sur de los 40° S, está actualmente habitada por Chaetophractus villosus y Zaedyus pichiy. Con el objeto de reconstruir la historia de estos armadillos en la porción austral de América del Sur durante el Pleistoceno tardío-Holoceno, compilamos y discutimos datos de registros zooarqueológicos, observaciones de naturalistas y viajeros, especímenes de museos y datos de campo. Encontramos que ambas especies experimentaron una considerable expansión de su distribución hacia el sur. De acuerdo a la evidencia obtenida concluimos que: (a) Patagonia austral estuvo básicamente libre de armadillos durante el Pleistoceno tardío- Holoceno temprano; (b) durante los últimos 10 ka, Z. pichiy invadió progresivamente el sur de la Patagonia desde el norte... |

| The present study aimed to evaluate the effect of bromoxynil herbicide on soil microorganisms, with the hypothesis that this herbicide caused suppression in microbial activity and biomass by exerting toxic effect on them. Nine sites of Punjab province (Pakistan) those had been exposed to bromoxynil herbicide for about last ten years designated as soil 'A' were surveyed in 2011 and samples were collected and analyzed for Microbial Biomass Carbon (MBC), Biomass Nitrogen (MBN), Biomass Phosphorus (MBP) and bacterial population. Simultaneously, soil samples from the same areas those were not exposed to herbicide designated as soil 'B' were taken. At all the sites MBC, MBN and MBP ranged from 131 to 457, 1.22 to 13.1 and 0.59 to 3.70 µg g-1 in the contaminated... |

| Previous studies of marine sequences from the Faroe Islands region have identified a series of coarse-grained tephra horizons deposited during Marine Isotope Stage (MIS) 5. Here we reassess the MIS 5 tephrostratigraphy of the Faroe Islands region and focus on the cryptotephra deposits preserved within the fine-grained fraction of marine core LINK 16. We also extend the record to encompass the late MIS 6 and early MIS 4 periods. A density separation technique, commonly used for tephra investigations in lacustrine settings but rarely applied to marine sediments, is utilised to explore the fine-grained material and EPMA and LA-ICP-MS are employed to determine the major and trace element composition of individual tephra shards. In total, 3 basaltic and 3... |

| There are currently many devices and techniques to quantify trace elements (TEs) in various matrices, but their efficacy is dependent on the digestion methods (DMs) employed in the opening of such matrices which, although "organic", present inorganic components which are difficult to solubilize. This study was carried out to evaluate the recovery of Fe, Zn, Cr, Ni, Cd and Pb contents in samples of composts and cattle, horse, chicken, quail, and swine manures, as well as in sewage sludges and peat. The DMs employed were acid digestion in microwaves with HNO3 (EPA 3051A); nitric-perchloric digestion with HNO3 + HClO4 in a digestion block (NP); dry ashing in a muffle furnace and solubilization of residual ash in nitric acid (MDA); digestion by using aqua... |

| Larval development of Physocephala (Diptera, Conopidae) in the bumble bee Bombus morio (Hymenoptera, Apidae). In the summer of 2012, a high incidence of conopid larvae was observed in a sample of female B. morio collected in remaining fragments of semidecidual forest and Cerrado, in the municipality of Sorocaba, state of São Paulo, Brazil. The larval development of conopid flies was studied, beginning at the larval instars (LO to L3) and PUP, until the emergence of the imago under laboratory conditions and inside the host. At the first instar, or LO, the microtype larvae measured less than 1 mm in length. During the transition from L1 to L3, the larvae grew in length. At L3, the larvae doubled their length (4 mm) and then started to develop both in length... |

| Abstract: The percent of sugarcane mechanical sugarcane loading (in Egypt) has not been exceeded 10% because of the poor finance-ability of the farmers to by the imported self-propelled loaders. The local workshops have been attempting to fabricate a sugarcane loader attached to the farm tractors as a cheap alternative. Farmers did not accept the tractor-mounted loaders fabricated locally because of the problems concerning poor efficiency and poor balance of the tractor-mounted loader while operation. The main objective was to overcome the problems concerning precise fabrication of the tractor-front-mounted loader and to develop an efficient dynamically balanced machine. Fabricating a sugarcane grab loader for the tractor faces difficulties due to the... |

| Dothiorella and Spencermartinsia are two botryosphaeriaceous genera with dark 2-celled conidia and found in parasitic, saprophytic or endophytic association with various woody host plants. Based on ITS and EF1-α sequence data and morphology, eight new species are described from Iran, New Zealand, Portugal and Spain. Of these, five species are placed in Dothiorella, namely D. iranica, D. parva, D. prunicola, D. sempervirentis and D. striata, and three species belong to Spencermartinsia named as S. citricola, S. mangiferae and S. plurivora. An identification key to the species of each genus is provided. |

| An in-house loop-mediated isothermal amplification (LAMP) reaction was established and evaluated for sensitivity and specificity in detecting the presence of Salmonella Typhi (S. Typhi) isolates from Kelantan, Malaysia. Three sets of primers consisting of two outer and 4 inner were designed based on locus STBHUCCB_38510 of chaperone PapD of S. Typhi genes. The reaction was optimised using genomic DNA of S. Typhi ATCC7251 as the template. The products were visualised directly by colour changes of the reaction. Positive results were indicated by green fluorescence and negative by orange colour. The test was further evaluated for specificity, sensitivity and application on field samples. The results were compared with those obtained by gold standard culture... |
