The results of a phylogenetic and chemotaxonomic analysis of the genus Micrococcus indicated that it is significantly heterogeneous. Except for Micrococcus lylae, no species groups phylogenetically with the type species of the genus, Micrococcus luteus. The other members of the genus form three separate phylogenetic lines which on the basis of chemotaxonomic properties can be assigned to four genera. These genera are the genus Kocuria gen. nov. for Micrococcus roseus, Micrococcus varians, and Micrococcus kristinae, described as Kocuria rosea comb. nov., Kocuria varians comb. nov., and Kocuria kristinae comb. nov., respectively; the genus Nesterenkonia gen. nov. for Micrococcus halobius, described as Nesterenkonia halobia comb. nov.; the genus Nesterenkonia gen. nov. for Micrococcus halobius, described as Nesterenkonia halobia comb. nov.; the genus Dermacoccus gen. nov. for Micrococcus nishinomiyaensis, described as Dermacoccus nishinomiyaensis comb. nov.; and the genus Kytocossus gen. nov. for Micrococcus sedentarius, described as Kytococcus sedentarius comb. nov. M. luteus and M. lylae, which are closely related phylogenetically but differ in some chemotaxonomic properties, are the only species that remain in the genus Micrococcus Cohn 1872. An emended description of the genus Micrococcus is given [corrected].

Full Text Available Introduction: Inappropriate advice interferes with the students’ achievement of educational and professional goals and they may fail to use proper resources for their educational needs. The present study was carried out to compare the students’ satisfaction about the performance of academic advisors before and after the advisor project in Shahrekord University of Medical Sciences. Methods: This longitudinal study was carried out using census report on 244 students in different courses at Shahrekord University of Medical Sciences in two stages at the first semester of 2010-2011 and first semester of 2011-2012. To collect the data, we used a self-designed questionnaire including individual and educational information and 10 multiple-choice questions with Likert scale to assess the students’ satisfaction about the advisors’ performance. Data were analyzed in SPSS 14 using paired t-test, qui-square test. P<0.05 was considered significant. Results: Of the ten items of satisfaction, there was only a significant difference in “accessibility to an advisor before and after the advisor project in students of nursing and midwifery school” (p=0.010, and the difference was not significant in other items in these students. No significant difference was found in ten items of satisfaction in students at other schools before and after the advisor project (p=0.010. Conclusion: It seems that the implementation of advisor project could not provide a satisfactory position for students. Adequate supervision of university officials on proper implementation of the advisor project, supporting faculty advisors and strengthening their position can help to improve the process.

The process of candidates choose graduate programs: an analysis from the advisor perspective

This study aims to identify the criteria used by advisors in the decision-making on whether to accept a candidate for mentoring in a postgraduate strictu sensu program and examines possible relationships between this decision and their scientific production and mentees evasion. In order to meet these goals one seeks to identify and analyze the selection criteria of candidates for the master's and doctorate programs at an institution; in this case, the Energy and Nuclear Research Institute - IPEN. More specifically, one seeks to study similarities and differences between those criteria among the advisors; find out whether there is a correlation between the selection criteria and the advisors characteristics (Profile); identify the selection process used by advisors and point out which are the motivations that lead to evasion according to their point of view. To meet these challenges, as the starting point of the research, a conceptual model was designed in order to form the basis for the preparation of the script for the interviews with open-ended questions as to identify the selection criteria used by a small group of advisors with a predefined profile. From that point, based on the responses obtained in interviews, the survey was expanded to all advisors working in the IPEN Postgraduate program by implementing an online survey using Google Docs app for data collection. These data were then analyzed and reorganized according to an operational model of research that would guide the analysis by structural equation modeling (SEM) by means of the SmartPLS software, in order to identify the presence or absence of correlation between the criteria adopted by the advisors and their academic production and the evasion of their mentees, for that one relied on studies in: Bazerman and Moore (2010); Cohen (1988); Hair Jr. et al (2009); Hansmann and Ringle (2004); Martins (1997); Ringle, C.; Silva and Bido (2014); Sousa (2007); Sousa and Yu (2014); Torres (2014); Yu (2011

A Gram-positive, halophilic actinobacterial strain Miq-12 T was isolated from Meighan wetland in Iran. Strain Miq-12 T was strictly aerobic, catalase positive and oxidase negative. The isolate grew at 12-25 % NaCl, at 30-50 °C and pH 5.5-10.5. The optimum NaCl, temperature and pH for growth were 15-20 %, 40 °C and 7.0-8.0, respectively. The cell wall of strain Miq-12 T contained meso-diaminopimelic acid as diagnostic diamino acid and arabinose as whole-cell sugar. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine and phosphatidylinositol. It synthesized cellular fatty acids of anteiso and iso-branched types, anteiso-C17 : 0, iso-C17:0, iso-C15:0, iso-C16 : 0. The major respiratory quinone was MK-9(H4). The G+C content of its genomic DNA was 72.1 mol%. Phylogenetic analysis based on 16S rRNA gene sequence comparison revealed that strain Miq-12 T belongs to the family Pseudonocardiaceae, constituted a separate clade, and showed the closest phylogenetic similarity to Saccharopolyspora aidingensis TRM 46074 T (96.99 %) and Saccharopolyspora ghardaiensis CCUG 63370 T (96.92 %). On the basis of phylogenetic analysis, phenotypic and chemotaxonomic characteristics, a novel genus and species of the family Pseudonocardiaceae, Salinifilum proteinilyticum gen. nov., sp. nov., are proposed. The type strain is Miq-12 T (=IBRCM 11033 T =LMG 28390 T ). We also propose that S. aidingensis and S. ghardaiensis should be transferred to this new genus and be named Salinifilum aidingensis comb. nov. and Salinifilum ghardaiensis comb. nov., respectively. The type strain of Salinifilum aidingensis comb. nov. is TRM 46074 T (=CCTCCAA 2012014 T =JCM 30185 T ) and the type strain of Salinifilum ghardaiensis comb. nov. is CCUG 63370 T (=DSM 45606 T =CECT 8304 T ).

The type species of the genus Paraglaciecola is Paraglaciecola mesophila. An emended description of the genus Glaciecola is provided. In addition, a novel strain, 162Z-12(T), was isolated from seawater collected as part of an iron fertilization experiment (LOHAFEX) conducted in the Southern Ocean in 2009 and was subjected to polyphasic taxonomic characterization. Cells of 162Z-12(T) were Gram-negative, aerobic, motile, ovoid to short rod-shaped, obligatorily halophilic and possessed all the characteristics of the genus Paraglaciecola. Strain 162Z-12(T) shared the highest 16S rRNA gene sequence similarity with the type strains of P. agarilytica (99.7 %), P. chathamensis (99.7 %), P. mesophila (98.5 %) and P. polaris (98.3 %). However, it exhibited DNA-DNA relatedness of less than 70.0 % with its nearest phylogenetic relatives, well below the threshold value for species delineation. Further, strain 162Z-12(T) differed from the nearest species in several phenotypic characteristics, in addition to the occurrence of unique nucleotides G, T, T and T at positions 1194, 1269, 1270 and 1271 of the 16S rRNA gene. Based on the cumulative differences it exhibited from its nearest phylogenetic neighbours, strain 162Z-12(T) was identified as a novel member of the genus Paraglaciecola and assigned to the novel species Paraglaciecola oceanifecundans sp. nov. The type strain of Paraglaciecola oceanifecundans is 162Z-12(T) ( = KCTC 32337(T) = LMG 27453(T)). © 2014 IUMS.

Phylogenetic relationships among marine Alteromonas-like proteobacteria: emended description of the family Alteromonadaceae and proposal of Pseudoalteromonadaceae fam. nov., Colwelliaceae fam. nov., Shewanellaceae fam. nov., Moritellaceae fam. nov., Ferrimonadaceae fam. nov., Idiomarinaceae fam. nov. and Psychromonadaceae fam. nov.

The phylogenetic relationships among marine Alteromonas-like bacteria of the genera Alteromonas, Pseudoalteromonas, Glaciecola, Thalassomonas, Colwellia, Idiomarina, Oceanimonas, Oceanisphaera, Shewanella, Moritella, Ferrimonas, Psychromonas and several other genera of the 'Gammaproteobacteria' were studied. Results of 16S rRNA gene sequence analyses revealed that some members of these genera formed several coherent groups at the family level. Characteristic signature oligonucleotides for studied taxa were defined. Signature positions are divided into three classes: (i) single compensatory mutations, (ii) double compensatory mutations and (iii) mutations affecting nucleotides not paired in the secondary structure. The 16S rRNA gene sequence similarity level within genera was 93 % or above. This value can be a useful additional criterion for genus discrimination. On the basis of this work and previous polyphasic taxonomic studies, the circumscription of the family Alteromonadaceae is limited to the genera Alteromonas and Glaciecola and the creation is proposed of the families Pseudoalteromonadaceae fam. nov. to accommodate bacteria of the genera Pseudoalteromonas and Algicola gen. nov. (formerly Pseudoalteromonas bacteriolytica) and Colwelliaceae fam. nov. to accommodate bacteria of the genera Colwellia and Thalassomonas. Bacteria of the genera Oceanimonas and Oceanisphaera formed a robust cluster and shared common signature oligonucleotides. Because of deep branching and lack of association with any other genus, the following families are proposed that include single genera: Idiomarinaceae fam. nov., Psychromonadaceae fam. nov., Moritellaceae fam. nov., Ferrimonadaceae fam. nov. and Shewanellaceae fam. nov. Finally, this study also revealed that [Hyphomicrobium] indicum should be reclassified as Photobacterium indicum comb. nov.

Full Text Available The purpose of this article is to study the academic advisors’ profile from the attitudes in the learning process view point, being the center of which the need that as an educator, the advisor has to be a leader educated in values. The research was documental, according to the theoretical contributions of Arana and Batista (2006,  Ortega and Minguez (2001 and Denis (2000, among others. It is concluded that an academic advisor in values allows individual and collective trasnformation and an education without values as its center, it is a hollow and useless education.

Automated Advice: A Portfolio Management Perspective on Robo-Advisors

In this paper we investigate the predominant robo-advisor model, uncovering that however novel this solution might be, it also relies religiously on imperative contributions to modern portfolio theory that have been made in the past half a century. Despite conforming by and large to passive investment, we find that the slight variations in the methodologies used by robo-advisors introduce significant variability in risk-adjusted returns across the robo-advisor spectrum. Nonetheless, our perfo...

During the study of bacteria associated with bats affected by white-nose syndrome hibernating in caves in the Czech Republic, we isolated two facultatively anaerobic, Gram-stain-negative bacteria, designated strains 12(T) and 52(T). Strains 12(T) and 52(T) were motile, rod-like bacteria (0.5-0.6 µm in diameter; 1-1.3 µm long), with optimal growth at 20-35 °C and pH 6-8. On the basis of the almost complete sequence of their 16S rRNA genes they should be classified within the genus Serratia; the closest relatives to strains 12(T) and 52(T) were Serratia quinivorans DSM 4597(T) (99.5 % similarity in 16S rRNA gene sequences) and Serratia ficaria DSM 4569(T) (99.5% similarity in 16S rRNA gene sequences), respectively. DNA-DNA relatedness between strain 12(T) and S. quinivorans DSM 4597(T) was only 37.1% and between strain 52(T) and S. ficaria DSM 4569(T) was only 56.2%. Both values are far below the 70% threshold value for species delineation. In view of these data, we propose the inclusion of the two isolates in the genus Serratia as representatives of Serratia myotis sp. nov. (type strain 12(T) =CECT 8594(T) =DSM 28726(T)) and Serratia vespertilionis sp. nov. (type strain 52(T) =CECT 8595(T) =DSM 28727(T)). © 2015 IUMS.

Reclassification of rhizosphere bacteria including strains causing corky root of lettuce and proposal of Rhizorhapis suberifaciens gen. nov., comb. nov., Sphingobium mellinum sp. nov., Sphingobium xanthum sp. nov. and Rhizorhabdus argentea gen. nov., sp. nov.

The genus Rhizorhapis gen. nov. (to replace the illegitimate genus name Rhizomonas) is proposed for strains of Gram-negative bacteria causing corky root of lettuce, a widespread and important lettuce disease worldwide. Only one species of the genus Rhizomonas was described, Rhizomonas suberifaciens, which was subsequently reclassified as Sphingomonas suberifaciens based on 16S rRNA gene sequences and the presence of sphingoglycolipid in the cell envelope. However, the genus Sphingomonas is so diverse that further reclassification was deemed necessary. Twenty new Rhizorhapis gen. nov.- and Sphingomonas-like isolates were obtained from lettuce or sow thistle roots, or from soil using lettuce seedlings as bait. These and previously reported isolates were characterized in a polyphasic study including 16S rRNA gene sequencing, DNA-DNA hybridization, DNA G+C content, whole-cell fatty acid composition, morphology, substrate oxidation, temperature and pH sensitivity, and pathogenicity to lettuce. The isolates causing lettuce corky root belonged to the genera Rhizorhapis gen. nov., Sphingobium, Sphingopyxis and Rhizorhabdus gen. nov. More specifically, we propose to reclassify Rhizomonas suberifaciens as Rhizorhapis suberifaciens gen. nov., comb. nov. (type strain, CA1(T) = LMG 17323(T) = ATCC 49355(T)), and also propose the novel species Sphingobium xanthum sp. nov., Sphingobium mellinum sp. nov. and Rhizorhabdus argentea gen. nov., sp. nov. with the type strains NL9(T) ( = LMG 12560(T) = ATCC 51296(T)), WI4(T) ( = LMG 11032(T) = ATCC 51292(T)) and SP1(T) ( = LMG 12581(T) = ATCC 51289(T)), respectively. Several strains isolated from lettuce roots belonged to the genus Sphingomonas, but none of them were pathogenic.

Five strains, designated WS 4672T, WS 4998, WS 4992T, WS 4997 and WS 5000, isolated from bovine raw milk formed two individual groups in a phylogenetic analysis. The most similar species on the basis of 16S rRNA gene sequences were Pseudomonas azotoformans IAM 1603T, Pseudomonas gessardii CIP 105469T and Pseudomonas libanensis CIP 105460T showing 99.7-99.6 % similarity. Using rpoD gene sequences Pseudomonas veronii LMG 17761T (93.3 %) was most closely related to strain WS 4672T and Pseudomonas libanensis CIP 105460T to strain WS 4992T (93.3 %). The five strains could be differentiated from their closest relatives and from each other by phenotypic and chemotaxonomic characterization and ANIb values calculated from draft genome assemblies. ANIb values of strains WS 4992T and WS4671T to the closest relatives are lower than 90 %. The major cellular polar lipids of both strains are phosphatidylethanolamine, phosphatidylglycerol, a phospholipid and diphosphatidylglycerol, and their major quinone is Q-9. The DNA G+C content of strains WS 4992T and WS 4672T were 60.0  and 59.7  mol%, respectively. Based on these genotypic and phenotypic traits two novel species of the genus Pseudomonas are proposed: Pseudomonas lactis sp. nov. [with type strain WS 4992T (=DSM 29167T=LMG 28435T) and the additional strains WS 4997 and WS 5000], and Pseudomonasparalactis sp. nov. [with type strain WS 4672T (=DSM 29164T=LMG 28439T) and additional strain WS 4998].

Two strains of Gram-negative, methylotrophic bacteria, isolated because of their abilities to promote plant growth, were subjected to a polyphasic taxonomic study. The isolates were strictly aerobic, motile, pink-pigmented, facultatively methylotrophic, non-spore-forming rods. The chemotaxonomic characteristics of the isolates included the presence of C18 : 1ω7c as the major cellular fatty acid. The DNA G+C contents of strains BL36(T) and BL47(T) were 69.4 and 69.8 mol%, respectively. 16S rRNA gene sequence analysis of strains BL36(T) and BL47(T) placed them under the genus Methylobacterium, with the pairwise sequence similarity between them and the type strains of closely related species ranging from 97.2 to 99.0%. On the basis of their phenotypic and phylogenetic distinctiveness and the results of DNA-DNA hybridization analysis, the isolates represent two novel species within the genus Methylobacterium, for which the names Methylobacterium pseudosasicola sp. nov. (type strain BL36(T) = NBRC 105203(T) = ICMP 17621(T)) and Methylobacterium phyllostachyos sp. nov. (type strain BL47(T) = NBRC 105206(T) = ICMP 17619(T)) are proposed. © 2014 IUMS.

The network infrastructures have been rapidly upgraded in many high-performance networks (HPNs). However, such infrastructure investment has not led to corresponding performance improvement in big data transfer, especially at the application layer, largely due to the complexity of optimizing transport control on end hosts. We design and implement ProbData, a PRofiling Optimization Based DAta Transfer Advisor, to help users determine the most effective data transfer method with the most appropriate control parameter values to achieve the best data transfer performance. ProbData employs a profiling optimization based approach to exploit the optimal operational zone of various data transfer methods in support of big data transfer in extreme scale scientific applications. We present a theoretical framework of the optimized profiling approach employed in ProbData as wellas its detailed design and implementation. The advising procedure and performance benefits of ProbData are illustrated and evaluated by proof-of-concept experiments in real-life networks.

A multi-gene (SSU, LSU, psbA and COI) molecular phylogeny of the family Corallinaceae (excluding the subfamilies Lithophylloideae and Corallinoideae) showed a paraphyletic grouping of six monophyletic clades. Pneophyllum and Spongites were reassessed and recircumscribed using DNA sequence data integrated with morpho-anatomical comparisons of type material and recently collected specimens. We propose Chamberlainoideae subfam. nov., including the type genus Chamberlainium gen. nov., with C. tumidum comb. nov. as the generitype, and Pneophyllum. Chamberlainium is established to include several taxa previously ascribed to Spongites, the generitype of which currently resides in Neogoniolithoideae. Additionally we propose two new genera, Dawsoniolithon gen. nov. (Metagoniolithoideae), with D. conicum comb. nov. as the generitype and Parvicellularium gen. nov. (subfamily incertae sedis), with P. leonardi sp. nov. as the generitype. Chamberlainoideae has no diagnostic morpho-anatomical features that enable one to assign specimens to it without DNA sequence data, and it is the first subfamily to possess both Type 1 (Chamberlainium) and Type 2 (Pneophyllum) tetra/bisporangial conceptacle roof development. Two characters distinguish Chamberlainium from Spongites: tetra/biasporangial conceptacle chamber diameter (300 μm in Spongites) and tetra/bisporangial conceptacle roof thickness (8 cells in Spongites).

Two novel actinobacteria, designated strains NEAU-Jh1-4T and NEAU-Wp2-0T, were isolated from muddy soil collected from a riverbank in Jiaohe and a dandelion root collected from Harbin, respectively. A polyphasic study was carried out to establish the taxonomic positions of these two strains. The phylogenetic analysis based on the 16S rRNA gene sequences of strains NEAU-Jh1-4T and NEAU-Wp2-0T indicated that strain NEAU-Jh1-4T clustered with Streptosporangium nanhuense NEAU-NH11T (99.32 % 16S rRNA gene sequence similarity), Streptosporangium purpuratum CY-15110T (98.30 %) and Streptosporangium yunnanense CY-11007T (97.95 %) and strain NEAU-Wp2-0T clustered with 'Streptosporangium sonchi  ' NEAU-QS7 (99.39 %), 'Streptosporangium kronopolitis' NEAU-ML10 (99.26 %), 'Streptosporangium shengliense' NEAU-GH7 (98.85 %) and Streptosporangium longisporum DSM 43180T (98.69 %). Moreover, morphological and chemotaxonomic properties of the two isolates also confirmed their affiliation to the genus Streptosporangium. However, the low level of DNA-DNA hybridization and some phenotypic characteristics allowed the isolates to be differentiated from the most closely related species. Therefore, it is proposed that strains NEAU-Jh1-4T and NEAU-Wp2-0T represent two novel species of the genus Streptosporangium, for which the name Streptosporangium jiaoheense sp. nov. and Streptosporangium taraxaci sp. nov. are proposed. The type strains are NEAU-Jh1-4T (=CGMCC 4.7213T=JCM 30348T) and NEAU-Wp2-0T (=CGMCC 4.7217T=JCM 30349T), respectively.

The challenges of science journalism: The perspectives of scientists, science communication advisors and journalists from New Zealand.

Science.gov (United States)

Ashwell, Douglas James

2016-04-01

The news media play an important role in informing the public about scientific and technological developments. Some argue that restructuring and downsizing result in journalists coming under increased pressure to produce copy, leading them to use more public relations material to meet their deadlines. This article explores science journalism in the highly commercialised media market of New Zealand. Using semi-structured interviews with scientists, science communication advisors and journalists, the study finds communication advisors and scientists believe most media outlets, excluding public service media, report science poorly. Furthermore, restructuring and staff cuts have placed the journalists interviewed under increasing pressure. While smaller newspapers appear to be printing press releases verbatim, metropolitan newspaper journalists still exercise control over their use of such material. The results suggest these journalists will continue to resist increasing their use of public relations material for some time to come. © The Author(s) 2014.

Taxonomic evaluation of the genus Enterobacter based on multilocus sequence analysis (MLSA): proposal to reclassify E. nimipressuralis and E. amnigenus into Lelliottia gen. nov. as Lelliottia nimipressuralis comb. nov. and Lelliottia amnigena comb. nov., respectively, E. gergoviae and E. pyrinus into Pluralibacter gen. nov. as Pluralibacter gergoviae comb. nov. and Pluralibacter pyrinus comb. nov., respectively, E. cowanii, E. radicincitans, E. oryzae and E. arachidis into Kosakonia gen. nov. as Kosakonia cowanii comb. nov., Kosakonia radicincitans comb. nov., Kosakonia oryzae comb. nov. and Kosakonia arachidis comb. nov., respectively, and E. turicensis, E. helveticus and E. pulveris into Cronobacter as Cronobacter zurichensis nom. nov., Cronobacter helveticus comb. nov. and Cronobacter pulveris comb. nov., respectively, and emended description of the genera Enterobacter and Cronobacter.

The taxonomy of Enterobacter has a complicated history, with several species transferred to and from this genus. Classification of strains is difficult owing to its polyphyletic nature, based on 16S rRNA gene sequences. It has been previously acknowledged that Enterobacter contains species which should be transferred to other genera. In an attempt to resolve the taxonomy of Enterobacter, MLSA based on partial sequencing of protein-encoding genes (gyrB, rpoB, infB and atpD) was performed on the type strains and reference strains of Enterobacter, Cronobacter and Serratia species, as well as members of the closely related genera Citrobacter, Klebsiella, Kluyvera, Leclercia, Mangrovibacter, Raoultella and Yokenella. Phylogenetic analyses of the concatenated nucleotide sequences revealed that Enterobacter can be divided into five strongly supported MLSA groups, suggesting that the species should be reclassified into five different genera. Further support for this was provided by a concatenated amino acid tree, phenotypic characteristics and fatty acid profiles, enabling differentiation of the MLSA groups. Three novel genera are proposed: Lelliottia gen. nov., Pluralibacter gen. nov. and Kosakonia gen. nov. and the following new combinations: Lelliottia nimipressuralis comb. nov., Lelliottia amnigena comb. nov., Pluralibacter gergoviae comb. nov., Pluralibacter pyrinus comb. nov., Kosakonia cowanii comb. nov., Kosakonia radicincitans comb. nov., Kosakonia oryzae comb. nov., Kosakonia arachidis comb. nov., Cronobacter helveticus comb. nov. and Cronobacter pulveris comb. nov. Additionally, the novel epithet Cronobacter zurichensis nom. nov. is proposed for the reclassification of Enterobacter turicensis into the genus Cronobacter, as Cronobacter turicensis (Iversen et al., 2008) is already in use.

Proposal for creation of a new genus Neomicrococcus gen. nov. to accommodate Zhihengliuella aestuarii Baik et al. 2011 and Micrococcus lactis Chittpurna et al. 2011 as Neomicrococcus aestuarii comb. nov. and Neomicrococcus lactis comb. nov.

Micrococcus lactis and Zhihengliuella aestuarii were described independently in 2011. Their type strains showed high levels of 16S rRNA gene sequence similarity (99.3%). Phylogenetic analysis revealed that M. lactis MCC 2278T and Z. aestuarii JCM 16166T formed a monophyletic group and showed distant relationships to other members of closely related genera such as Micrococcus, Zhihengliuella, Arthrobacter and Citricoccus. The presence of large proportions of iso-C14:0 and iso-C16:0 with small amounts of iso-C15:0 distinguished M. lactis MCC 2278T and Z. aestuarii JCM 16166T from other members of the genera Micrococcus and Zhihengliuella. Unlike other members of the genera Zhihengliuella and Micrococcus, M. lactis MCC 2278T and Z. aestuarii JCM 16166T showed growth at low concentrations of NaCl. Thus, based on distinctive phylogenetic, chemotaxonomic and physiological features of these two organisms in comparison with other members of the genera Micrococcus and Zhihengliuella, it is clear that they do not fit within the existing classification and deserve separate status. DNA-DNA hybridization between the two type strains was 63%, indicating that they represent separate species. In this study, we propose the creation of a novel genus, Neomicrococcus gen. nov., to accommodate the two species with Neomicrococcus aestuarii gen. nov., comb. nov. (type strain JCM 16166T = KCTC 19557T) as the type species. Neomicrococcus lactis comb. nov. (type strain MCC 2278T = DSM 23694T) is also proposed.

Two novel actinobacteria, designated strains NEAU-QS7(T) and NEAU-ML10(T), were isolated from a root of Sonchus oleraceus L. and a Kronopolites svenhedind Verhoeff specimen, respectively, collected from Wuchang, Heilongjiang Province, China. A polyphasic study was carried out to establish the taxonomic positions of these strains. The two strains were observed to form abundant aerial hyphae that differentiated into spherical spore vesicles. The phylogenetic analysis based on the 16S rRNA gene sequences of strains NEAU-QS7(T) and NEAU-ML10(T) showed that the two novel isolates exhibited 99.7 % 16S rRNA gene sequence similarity with each other and that they are most closely related to Streptosporangium shengliense NEAU-GH7(T) (99.1, 99.0 %) and Streptosporangium longisporum DSM 43180(T) (99.1, 99.0 %). However, the DNA-DNA hybridization value between strains NEAU-QS7(T) and NEAU-ML10(T) was 46.5 %, and the values between the two strains and their closest phylogenetic relatives were also below 70 %. With reference to phenotypic characteristics, phylogenetic data and DNA-DNA hybridization results, the two strains can be distinguished from each other and their closest phylogenetic relatives. Thus, strains NEAU-QS7(T) and NEAU-ML10(T) represent two novel species of the genus Streptosporangium, for which the names Streptosporangium sonchi sp. nov. and Streptosporangium kronopolitis sp. nov. are proposed. The type strains are NEAU-QS7(T) (=CGMCC 4.7142(T) =DSM 46717(T)) and NEAU-ML10(T) (=CGMCC 4.7153(T) =DSM 46720(T)), respectively.

A total of 18 strains, representing members of the genus Mesorhizobium, obtained from root nodules of woody legumes growing in Ethiopia, have been previously shown, by multilocus sequence analysis (MLSA) of five housekeeping genes, to form three novel genospecies. In the present study, the phylogenetic relationship between representative strains of these three genospecies and the type strains of their closest phylogenetic neighbours Mesorhizobium plurifarium, Mesorhizobium amorphae, Mesorhizobium septentrionale and Mesorhizobium huakuii was further evaluated using a polyphasic taxonomic approach. In line with our earlier MLSA of other housekeeping genes, the phylogenetic trees derived from the atpD and glnII genes grouped the test strains into three well-supported, distinct lineages that exclude all defined species of the genus Mesorhizobium. The DNA-DNA relatedness between the representative strains of genospecies I-III and the type strains of their closest phylogenetic neighbours was low (≤59 %). They differed from each other and from their closest phylogenetic neighbours by the presence/absence of several fatty acids, or by large differences in the relative amounts of particular fatty acids. While showing distinctive features, they were generally able to utilize a wide range of substrates as sole carbon and nitrogen sources. The strains belonging to genospecies I, II and III therefore represent novel species for which we propose the names Mesorhizobium shonense sp. nov., Mesorhizobium hawassense sp. nov. and Mesorhizobium abyssinicae sp. nov. The isolates AC39a(T) ( = LMG 26966(T) = HAMBI 3295(T)), AC99b(T) ( = LMG 26968(T) = HAMBI 3301(T)) and AC98c(T) ( = LMG 26967(T) = HAMBI 3306(T)) are proposed as type strains for the respective novel species.

Results are reported from an improved measurement of νμ→νe transitions by the NOvA experiment. Using an exposure equivalent to 6.05 ×1 020 protons on target, 33 νe candidates are observed with a background of 8.2 ±0.8 (syst.). Combined with the latest NOvA νμ disappearance data and external constraints from reactor experiments on sin22 θ13, the hypothesis of inverted mass hierarchy with θ23 in the lower octant is disfavored at greater than 93% C.L. for all values of δC P.

Several species of the genus Penicillium were isolated during a survey of the mycobiota of leaf litter and soil in Colombian Amazon forest. Five species, Penicillium penarojense sp. nov. (type strain CBS 113178(T) = IBT 23262(T)), Penicillium wotroi sp. nov. (type strain CBS 118171(T) = IBT 23253(T)), Penicillium araracuarense sp. nov. (type strain CBS 113149(T) = IBT 23247(T)), Penicillium elleniae sp. nov. (type strain CBS 118135(T) = IBT 23229(T)) and Penicillium vanderhammenii sp. nov. (type strain CBS 126216(T) = IBT 23203(T)) are described here as novel species. Their taxonomic novelty was determined using a polyphasic approach, combining phenotypic, molecular (ITS and partial β-tubulin sequences) and extrolite data. Phylogenetic analyses showed that each novel species formed a unique clade for both loci analysed and that they were most closely related to Penicillium simplicissimum, Penicillium janthinellum, Penicillium daleae and Penicillium brasilianum. An overview of the phylogeny of this taxonomically difficult group is presented, and 33 species are accepted. Each of the five novel species had a unique extrolite profile of known and uncharacterized metabolites and various compounds, such as penicillic acid, andrastin A, pulvilloric acid, paxillin, paspaline and janthitrem, were commonly produced by these phylogenetically related species. The novel species had a high growth rate on agar media, but could be distinguished from each other by several macro- and microscopical characteristics.

A Gram-positive staining, rod-shaped, non-motile, spore-forming obligately anaerobic bacterium, designated CRIBT, was isolated from the gastro-intestinal tract of a rat and characterized. The major cellular fatty acids of strain CRIBT were saturated and unsaturated straight-chain C12-C19 fatty acids, with C16:0 being the predominant fatty acid. The polar lipid profile comprised six glycolipids, four phospholipids and one lipid that did not stain with any of the specific spray reagents used. The only quinone was MK-6. The predominating cell-wall sugars were glucose and galactose. The peptidoglycan type of strain CRIBT was A1σ lanthionine-direct. The genomic DNA G+C content of strain CRIBT was 28.1 mol%. On the basis of 16S rRNA gene sequence similarity, strain CRIBT was most closely related to a number of species of the genus Clostridium, including Clostridium lituseburense (97.2%), Clostridium glycolicum (96.2%), Clostridium mayombei (96.2%), Clostridium bartlettii (96.0%) and Clostridium irregulare (95.5%). All these species show very low 16S rRNA gene sequence similarity (genus Clostridium. DNA-DNA hybridization with closely related reference strains indicated reassociation values below 32%. On the basis of phenotypic and genetic studies, a novel genus, Romboutsia gen. nov., is proposed. The novel isolate CRIBT (=DSM 25109T=NIZO 4048T) is proposed as the type strain of the type species, Romboutsia ilealis gen. nov., sp. nov., of the proposed novel genus. It is proposed that C. lituseburense is transferred to this genus as Romboutsia lituseburensis comb. nov. Furthermore, the reclassification into novel genera is proposed for C. bartlettii, as Intestinibacter bartlettii gen. nov., comb. nov. (type species of the genus), C. glycolicum, as Terrisporobacter glycolicus gen. nov., comb. nov. (type species of the genus), C. mayombei, as Terrisporobacter mayombei gen. nov., comb. nov., and C. irregulare, as Asaccharospora irregularis gen. nov., comb. nov. (type species

Student goal orientation in learning inquiry skills with modifiable software advisors

Science.gov (United States)

Shimoda, Todd Adrian

A computer support environment (SCI-WISE) for learning and doing inquiry was designed. The system incorporates software advisors that give task completion advice (eg., forming hypotheses), general purpose advice (e.g., brainstorming), or system modification advice. Advisors' knowledge includes concepts, strategies, examples, referrals to other advisors, and criteria for evaluating good products and skills. Students using SCI-WISE can select the advisors' advice type (specific, general, or hints), and when advisors give advice (anytime, alert, or ask). Students can also modify the advisors' knowledge. The system is designed partly on a theoretical framework that assumes giving students higher levels of agency will facilitate higher-level goal orientation (such as knowledge-building) and produce higher levels of competence. In two studies of sixth graders, science students took a pretest of an open-ended inquiry question and a questionnaire that measured their goal orientations. The students worked in pairs on an inquiry project about memory, using one of two versions of SCI-WISE, one modifiable and one not modifiable. After finishing the project, the students took a posttest similar to the pretest, and evaluated the system. The main hypotheses predicted that knowledge-oriented students using the modifiable version would rate the system higher, use it more effectively, and do better on the inquiry posttest than task-oriented students. The results supported many of the hypotheses generated from the theoretical framework. Knowledge-oriented students tended to rate SCI-WISE higher, use more general purpose and system development advisors, and select more general advice and hints than task-oriented students. On the posttest inquiry test, students with higher goal orientations scored higher on average, particularly when paired with another knowledge oriented student. The studies also showed that goal orientation was not correlated with grade point average. Finally, the

The problems of knowledge representation, knowledge base handling and design has been described for an Operator Advisor System in the Paks Nuclear Power Plant. The Operator Advisor System is to be implemented as a part of the 5th and 6th unit. The knowledge of the Operator Advisor system is described by a few elementary knowledge items (diagnostic event functions, fault graph, action trees), weighted directed graphs have been found as their common structure. List-type and relational representation of these graphs have been used for the on-line and off-line part of the knowledge base respectively. A uniform data base design and handling has been proposed which consists of a design system, a knowledge base editor and a knowledge base compiler

Two Gram-negative, motile, aerobic, catalase- and oxidase-positive, rod-shaped strains, designated ZS5-23(T) and ZS6-22(T), were respectively isolated from Antarctic coastal attached (fast) ice and surface seawater samples. Both strains could grow at 4-35 °C (optimum 30 °C) and in the absence of NaCl. Analyses of 16S rRNA gene sequences revealed that strains ZS5-23(T) and ZS6-22(T) were closely related to each other (99.0 % sequence similarity) and belonged to the class Gammaproteobacteria, with their closest relatives being Spongiibacter and Melitea species (93.1-94.3 % sequence similarity). The predominant cellular fatty acids in both strains were C₁₇:₁ω8c, C₁₇:₀ and summed feature 3 (C₁₆:₁ω7c and/or iso-C₁₅:₀ 2-OH). Genomic DNA G+C contents of strains ZS5-23(T) and ZS6-22(T) were 51.5 and 51.8 mol%, respectively. The DNA-DNA relatedness between strains ZS5-23(T) and ZS6-22(T) was 50.9 %. Strains ZS5-23(T) and ZS6-22(T) could be differentiated from each other and from Spongiibacter and Melitea species by differences in a number of phenotypic properties. Based on the data presented, strains ZS5-23(T) and ZS6-22(T) represent two novel species in a new genus in the class Gammaproteobacteria, for which the names Zhongshania antarctica gen. nov., sp. nov. (the type species) and Zhongshania guokunii sp. nov. are proposed. The type strain of Zhongshania antarctica is ZS5-23(T) ( = KACC 14066(T)  = CCTCC AB 209246(T)) and that of Zhongshania guokunii is ZS6-22(T) ( = KACC 14532(T)  = CCTCC AB 209247(T)).

Sixteen heparinase-producing isolates, related to Sphingobacterium heparinum, were grouped into three major clusters by SDS-PAGE and DNA-rRNA hybridizations. Based on a polyphasic approach, it was shown that isolates of two of these clusters and S. heparinum species belong to a new genus for which the name Pedobacter is proposed. The genus consists of Pedobacter heparinus comb. nov. (formerly Sphingobacterium heparinum), which is the type species, Pedobacter piscium comb. nov. (formerly Sphingobacterium piscium), Pedobacter africanus sp. nov. and Pedobacter saltans sp. nov. and four as-yet-unnamed DNA hybridization groups. All the previously named taxa can be discriminated by phenotypic features, but have strong overall similarities with representatives of the genus Sphingobacterium and the misclassified species [Flexibacter] canadensis. All these organisms constitute a separate rRNA branch in rRNA superfamily V for which the family Sphingobacteriaceae fam. nov. is proposed.

Two Gram-negative, rod-shaped bacteria were isolated from agricultural soils in Córdoba province in central Argentina. Their 16S rRNA gene sequences demonstrated that they belong to the genus Burkholderia, with Burkholderia zhejiangensis as most closely related formally named species; this relationship was confirmed through comparative gyrB sequence analysis. Whole-cell fatty acid analysis supported their assignment to the genus Burkholderia. Burkholderia sp. strain YI23, for which a whole-genome sequence is available, represents the same taxon, as demonstrated by its highly similar 16S rRNA (100% similarity) and gyrB (99.1-99.7%) gene sequences. The results of DNA-DNA hybridization experiments and physiological and biochemical characterization further substantiated the genotypic and phenotypic distinctiveness of the Argentinian soil isolates, for which the name Burkholderia cordobensis sp. nov. is proposed, with strain MMP81(T) ( = LMG 27620(T) = CCUG 64368(T)) as the type strain. © 2014 IUMS.

Velikanova, D. S.; Antoshkin, A. I.; Anfimov, N. V.; Samoylov, O. B.

2018-04-01

The NOvA experiment was built to study oscillation parameters, mass hierarchy, CP- violation phase in the lepton sector and θ23 octant, via vɛ appearance and vμ disappearance modes in both neutrino and antineutrino beams. These scientific goals require good knowledge about NOvA scintillator basic properties. The new test bench was constructed and upgraded at JINR. The main goal of this bench is to measure scintillator properties (for solid and liquid scintillators), namely α/β discrimination and Birk's coefficients for protons and other hadrons (quenching factors). This knowledge will be crucial for recovering the energy of the hadronic part of neutrino interactions with scintillator nuclei. α/β discrimination was performed on the first version of the bench for LAB-based and NOvA scintillators. It was performed again on the upgraded version of the bench with higher statistic and precision level. Preliminary result of quenching factors for protons was obtained. A technical description of both versions of the bench and current results of the measurements and analysis are presented in this work.

The influence of TripAdvisor portal on hotel bussines in Serbia

Directory of Open Access Journals (Sweden)

Čačić Krunoslav

2013-01-01

Full Text Available Numerous researches have shown the existence of influence of specialized Web 2.0 portals on hotel business. One of most famous portals of that kind is TripAdvisor. The goal of this work is to determine the degree and mode of representation of hotels in Serbia on TripAdvisor portal. The results of the conducted research show that in past years the number of hotels from Serbia represented on this portal has increased significantly. At the end of 2012 there have been registered 3.288 comments which evaluated the service quality of 165 hotels from Serbia. The average vote, on five-degree scale, calculated at the level of all represented hotels at the end of 2012 was 3,92. Considering that Belgrade represents the primarily business, administrative and touristic center of Serbia, on the Belgrade's hotels specimen there has been analyzed the connection between business performances of hotels expressed through indicator TREVPAR and their image on TripAdvisor expressed through average vote determined based on user's comments, as well as in relation with TripAdvisor Popularity Index (TPI. The results show the high degree of correlation between analyzed features on the specimen of Belgrade's hotels, in range of hotels of second (4* and third category (3*. Having in mind the results of conducted research it is obvious that the hotels managers from Serbia should adopt and implement the corresponding procedures of monitoring and adequate reactions on contents on TripAdvisor, considering their influence on behavior of modern consumer in hotels.

A Gram-negative, short rod-shaped, gliding motile, and pale pink-pigmented bacterial strain, designated 15J9-9 T , was isolated from the soil of Iho Tewoo Beach, Jeju Island, Korea, and characterized taxonomically using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain 15J9-9 T belonged to the family Cytophagaceae and was related to Larkinella bovis M2T2B15 T (96.5% similarity), Larkinella arboricola Z0532 T (95.3% similarity), and Larkinella insperata LMG 22510 T (95.2% similarity). The DNA G+C content of strain 15J9-9 T was 48 mol%. The detection of phosphatidylethanolamine, phosphatidylserine, two unknown aminophospholipids (APL 1 and APL 2 ), and two unknown polar lipids (L 1 and L 2 ) in polar lipid profile, menaquinone-7 as the predominant quinone, and a fatty acid profile of C 16:1 ω5c, iso-C 15:0 , and iso-C 17:0 3-OH as the major fatty acids supported the affiliation of strain 15J9-9 T to the genus Larkinella. Based on its phenotypic properties and phylogenetic distinctiveness, strain 15J9-9 T should be classified in the genus Larkinella as a representative of a novel species, for which the name Larkinella harenae sp. nov. is proposed. The type strain is 15J9-9 T (=KCTC 42999 T  = JCM 31656 T ).

2015-04-02

The proportion of women in medicine is approaching that of men, but female physicians are still in the minority as regards positions of power. Female physicians are struggling to reach the highest positions in academic medicine. One reason for the disparities between the genders in academic medicine is the fact that female physicians, in comparison to their male colleagues, have a lower rate of scientific publishing, which is an important factor affecting promotion in academic medicine. Clinical physicians work in a stressful environment, and the extent to which they can control their work conditions varies. The aim of this paper was to examine potential impeding and supportive work factors affecting the frequency with which clinical physicians publish scientific papers on academic medicine. Cross-sectional multivariate analysis was performed among 198 female and 305 male Swedish MD/PhD graduates. The main outcome variable was the number of published scientific articles. Male physicians published significantly more articles than female physicians p articles, as was collaborating with a former PhD advisor for both female physicians (OR = 2.97; 95% CI 1.22-7.20) and male physicians (OR = 2.10; 95% CI 1.08-4.10). Control at work was significantly associated with a higher number of published articles for male physicians only (OR = 1.50; 95% CI 1.08-2.09). Exhaustion had a significant negative impact on number of published articles among female physicians (OR = 0.29; 95% CI 0.12-0.70) whilst the publishing rate among male physicians was not affected by exhaustion. Women physicians represent an expanding sector of the physician work force; it is essential that they are represented in future fields of research, and in academic publications. This is necessary from a gender perspective, and to ensure that physicians are among the research staff in biomedical research in the future.

Factors leading to the involvement of Forensic Advisors in the Belgian criminal justice system.

Science.gov (United States)

Bitzer, Sonja

2018-04-01

Forensic Advisors at the National Institute for Criminalistics and Criminology in Brussels act as advising body to the magistrate regarding analytical possibilities and the usefulness of trace analysis in a case. Initially, their function was devised to assist in complex murder cases with unknown offender. However, in a previous study, the increasing diversity of the cases they are requested for has been observed (Bitzer et al., in press). In order to deepen our understanding of the decision steps in the criminal investigation process, the decision to involve a Forensic Advisor and the factors leading to their involvement were evaluated. The study focused on homicide, robbery and burglary cases with and without requests for a Forensic Advisor between January 2014 and June 2016. The factors were categorised into five knowledge dimensions: strategic, immediate, physical, criminal and utility. Decision tree modelling was carried out in order to identify the factors influencing the request for a Forensic Advisor in the case. The decision to request a Forensic Advisor differs between different types of offences. It also depends on the complexity of the case in terms of the number of traces and objects collected at the crime scene, and the availability of witness reports. Indeed, Forensic Advisors take the role of trace analysis coordinator by providing an overview of all available traces, objects, analyses and results. According to the principal implication factors and the performed case study, the contribution of Forensic Advisors consists mainly in summarising all information and advise on potential additional analyses. This might be explained by a loss of overview of the information and the possibilities regarding trace analysis by the magistrate responsible of the case. Copyright © 2018 Elsevier B.V.

Guide to good practices for the selection, training, and qualification of shift technical advisors

Energy Technology Data Exchange (ETDEWEB)

1993-02-01

The DOE Guide to Good Practices For The Selection, Training, and Qualification of Shift Technical Advisors can be used by any DOE nuclear facility that has implemented the shift technical advisor position. DOE Order 5480-20, ``Personnel Selection, Qualification, Training, and Staffing Requirements at DOE Reactor and Non-Reactor Nuclear Facilities,`` states that only Category A reactors must use shift technical advisor position. However, many DOE nuclear facilities have implemented the shift technical advisor position to provide independent on-shift technical advice and counsel to the shift operating personnel to help determine cause and mitigation of facility accidents. Those DOE nuclear facilities that have implemented or are going to implement the shift technical advisor position will find this guide useful. This guide addresses areas that may be covered by other training programs. In these cases, it is unnecessary (and undesirable) to duplicate these areas in the STA training program as long as the specific skills and knowledge essential for STAs are addressed. The guide is presented based on the premise that the trainee has not completed any facility-specific training other than general employee training.

Results: The majority of samples were from Nursing, Midwifery, and Public Health School and a few from Faculty of Medicine. The majority of students (41.8% agreed to have the same advisor from the first term to the last. Also the results showed that the functions of advisors were poor in the areas of constant supervision and monitoring of students’ educational status (35.8%, preparing the timetable for performing the personal or group counseling (41.8% and providing counseling sessions according to the timetable (42.3%. But their functions were fair in the areas of acceptable guidance of students in the educational problems (35.1%, and the advisor’s familiarity to educational regulations (43.9%. It is necessary to note that the advisor's ability in making the intimate relationship with students (37.1%, and the advisors’ motivation and tendency to guidance and counseling (30.1% were the two items evaluated excellent by students. Conclusion: It is necessary that advisors make the students familiar with educational regulations at the first semester of higher education. Also, the policies and regulations for advisors will clarify their activities and will help them to perform better.

How do incentives lead to deception in advisor-client interactions? Explicit and implicit strategies of self-interested deception.

Science.gov (United States)

Mackinger, Barbara; Jonas, Eva

2012-01-01

When confronted with important questions we like to rely on the advice of experts. However, uncertainty can occur regarding advisors' motivation to pursue self-interest and deceive the client. This can especially occur when the advisor has the possibility to receive an incentive by recommending a certain alternative. We investigated how the possibility to pursue self-interest led to explicit strategic behavior (bias in recommendation and transfer of information) and to implicit strategic behavior (bias in information processing: evaluation and memory). In Study 1 explicit strategic behavior could be identified: self-interested advisors recommended more often the self-serving alternative and transferred more self-interested biased information to their client compared to the advisor without specific interest. Also deception through implicit strategic behavior was identified: self-interested advisors biased the evaluation of information less in favor of the client compared to the control group. Self-interested advisors also remembered conflicting information regarding their self-interest worse compared to advisors without self-interest. In Study 2 beside self-interest we assessed accountability which interacted with self-interest and increased the bias: when accountability was high advisor's self-interest led to higher explicit strategic behavior (less transfer of conflicting information), and to higher implicit strategic behavior (devaluated and remembered less conflicting information). Both studies identified implicit strategic behavior as mediator which can explain the relation between self-interest and explicit strategic behavior. Results of both studies suggest that self-interested advisors use explicit and implicit strategic behavior to receive an incentive. Thus, advisors do not only consciously inform their clients "self-interested," but they are influenced unconsciously by biased information processing - a tendency which even increased with high

Five strains of bifidobacteria were isolated from faeces of a common marmoset (Callithrix jacchus) and a red-handed tamarin (Saguinus midas). The five isolates clustered inside the phylogenetic group of the genus Bifidobacterium but did not show high sequence similarities between the isolates and to known species in the genus by phylogenetic analysis based on 16S rRNA gene sequences. Sequence analyses of dnaJ1 and hsp60 also indicated their independent phylogenetic positions to each other in the Bifidobacterium cluster. DNA G+C contents of the species ranged from 57.3 to 66.3 mol%, which is within the values recorded for Bifidobacterium species. All isolates showed fructose-6-phosphate phosphoketolase activity.

Two Gram-negative, heterotrophic, aerobic, prosthecated, marine bacteria, designated strains MCS23T and MCS27T, were isolated from seawater samples. NaCl was required for growth. The major polar lipid detected in strain MCS27T was phosphatidylglycerol, whereas those detected in MCS23T were phosphatidylglycerol, sulfoquinovosyl diacylglycerol and 1,2-diacyl-3-α-d-glucuronopyranosyl-sn-glycerol taurineamide. The most abundant cellular fatty acids were C18 : 1ω7 and C16 : 0, hydroxyl-fatty acids were 3-OH C12 : 0 in both strains and 3-OH C11 : 0 in MCS23T. Strains MCS23T and MCS27T had DNA G+C contents of 57.0 and 55.0 mol%, respectively. The two strains shared 99.3 % 16S rRNA gene sequence similarity; levels of similarity with the type strains of species of the genus Henriciella were 99.4-97.8 % but DNA-DNA hybridizations were 53 % or lower. Besides their 16S rRNA gene sequences, the novel strains can be differentiated from other species of the genus Henriciella by cell morphology, lipid and fatty acid patterns and enzyme activities. The data obtained led to the identification of two novel species, for which the names Henriciella barbarensis sp. nov. (type strain MCS23T=LMG 28705T=CCUG 66934T) and Henriciella algicola sp. nov. (type strain MCS27T=LMG 29152T=CCUG 67844T) are proposed. As these two novel species are the first prosthecate species in the genus Henriciella, an emended genus description is also provided.

Recent rDNA sequencing of 25 isolates from a previous study, during which limonene-utilizing yeasts were isolated from monoterpene-rich environments by using 1,4-disubstituted cyclohexanes as sole carbon sources, led to the identification of four hitherto unknown Rhodotorula species. Analyses of the 26S rDNA D1/D2 region as well as the internal transcribed spacer (ITS) domain indicated that two isolates (CBS 8499(T) and CBS 10736) were identical and were closely related to Rhodotorula cycloclastica, a previously described limonene-utilizing yeast. These novel isolates differed from known yeast species and could be distinguished from R. cycloclastica by standard physiological tests. The other three isolates represent three novel Rhodotorula species, closely related to Sporobolomyces magnisporus. These three species could also be distinguished from other Rhodotorula species by standard physiological tests. Based on these results, we suggest that the new isolates represent novel species, for which the names Rhodotorula eucalyptica sp. nov. (type strain CBS 8499(T)  = NRRL Y-48408(T)), Rhodotorula pini sp. nov. (type strain CBS 10735(T)  = NRRL Y-48410(T)), Rhodotorula bloemfonteinensis sp. nov. (type strain CBS 8598(T)  = NRRL Y-48407(T)) and Rhodotorula orientis sp. nov. (type strain CBS 8594(T)  = NRRL Y-48719(T)) are proposed. R. eucalyptica and R. pini can also utilize limonene.

Within the frame of a biotechnological screening, we isolated two Pseudomonas strains from forest soil. 16S rRNA gene sequence analysis indicated that strain CCOS 864T shared 99.8 % similarity with Pseudomonas donghuensis HYST, while strain CCOS 865T shared 99.0 % similarity with Pseudomonas putida DSM 291T and lower similarity with other P. putida group type strains. Based on multilocus sequence analysis, the two strains were genotypically distinct from each other, each forming a separate clade. Strains CCOS 864T and CCOS 865T were Gram-stain-negative, motile and rod-shaped, growing at a temperature range of 4-37 °C. Strain CCOS 864T could be phenotypically distinguished from P. putida group species by the combination of gelatinase-positive reaction and positive growth on N-acetyl-d-glucosamine, p-hydroxyphenylacetic acid and inosine but lack of fluorescein production on King's B medium, while strain CCOS 865T could be distinguished from P. putida group species by the combination of positive growth with saccharic acid and negative growth with p-hydroxyphenylacetic acid and l-pyroglutamic acid. The major polar lipid for both strains was phosphatidylethanolamine; the major quinone was ubiquinone Q-9. DNA-DNA hybridization and average nucleotide identities confirmed the novel species status for the two strains. The DNA G+C contents of CCOS 864T and CCOS 865T were 62.1 and 63.8 mol%, respectively. The phenotypic, phylogenetic and DNA-DNA relatedness data support the suggestion that CCOS 864T and CCOS 865T represent two novel Pseudomonas species. The names Pseudomonas wadenswilerensis sp. nov. (type strain CCOS 864T=LMG 29327T) and Pseudomonas reidholzensis sp. nov. (type strain CCOS 865T=LMG 29328T) are proposed.

SPILC: An expert student advisor

1990-01-01

The Lamar University Computer Science Department serves about 350 undergraduate C.S. majors, and 70 graduate majors. B.S. degrees are offered in Computer Science and Computer and Information Science, and an M.S. degree is offered in Computer Science. In addition, the Computer Science Department plays a strong service role, offering approximately sixteen service course sections per long semester. The department has eight regular full-time faculty members, including the Department Chairman and the Undergraduate Advisor, and from three to seven part-time faculty members. Due to the small number of regular faculty members and the resulting very heavy teaching loads, undergraduate advising has become a difficult problem for the department. There is a one week early registration period and a three-day regular registration period once each semester. The Undergraduate Advisor's regular teaching load of two classes, 6 - 8 semester hours, per semester, together with the large number of majors and small number of regular faculty, cause long queues and short tempers during these advising periods. The situation is aggravated by the fact that entering freshmen are rarely accompanied by adequate documentation containing the facts necessary for proper counselling. There has been no good method of obtaining necessary facts and documenting both the information provided by the student and the resulting advice offered by the counsellors.

The filamentous cyanobacterial genus Moorea gen. nov., described here under the provisions of the International Code of Botanical Nomenclature, is a cosmopolitan pan-tropical group abundant in the marine benthos. Members of the genus Moorea are photosynthetic (containing phycocyanin, phycoerythrin, allophycocyanin and chlorophyll a), but non-diazotrophic (lack heterocysts and nitrogenase reductase genes). The cells (discoid and 25-80 µm wide) are arranged in long filaments (algae blooms and, due to morphological resemblance to the genus Lyngbya, this group has often been incorrectly cited in the literature. We here describe two species of the genus Moorea: Moorea producens sp. nov. (type species of the genus) with 3L(T) as the nomenclature type, and Moorea bouillonii comb. nov. with PNG5-198(R) as the nomenclature type.

The Astronaut Science Advisor (ASA, also known as Principal-Investigator-in-a-Box) is an advanced engineering effort to apply expert systems technology to experiment monitoring and control. Its goal is to increase the scientific value of information returned from experiments on manned space missions. The first in-space test of the system will be in conjunction with Professor Larry Young's (MIT) vestibulo-ocular 'Rotating Dome' experiment on the Spacelab Life Sciences 2 mission (STS-58) in the Fall of 1993. In a cost-saving effort, off-the-shelf equipment was employed wherever possible. Several modifications were necessary in order to make the system flight-worthy. The software consists of three interlocking modules. A real-time data acquisition system digitizes and stores all experiment data and then characterizes the signals in symbolic form; a rule-based expert system uses the symbolic signal characteristics to make decisions concerning the experiment; and a highly graphic user interface requiring a minimum of user intervention presents information to the astronaut operator. Much has been learned about the design of software and user interfaces for interactive computing in space. In addition, we gained a great deal of knowledge about building relatively inexpensive hardware and software for use in space. New technologies are being assessed to make the system a much more powerful ally in future scientific research in space and on the ground.

Genome-scale data suggest reclassifications in the Leisingera-Phaeobacter cluster including proposals for Sedimentitalea gen. nov. and Pseudophaeobacter gen. nov.

Full Text Available Earlier phylogenetic analyses of the marine Rhodobacteraceae (class Alphaproteobacteria genera Leisingera and Phaeobacter indicated that neither genus might be monophyletic. We here used phylogenetic reconstruction from genome-scale data, MALDI-TOF mass-spectrometry analysis and a re-assessment of the phenotypic data from the literature to settle this matter, aiming at a reclassification of the two genera. Neither Phaeobacter nor Leisingera formed a clade in any of the phylogenetic analyses conducted. Rather, smaller monophyletic assemblages emerged, which were phenotypically more homogeneous, too. We thus propose the reclassification of Leisingera nanhaiensis as the type species of a new genus as Sedimentitalea nanhaiensis gen. nov., comb. nov., the reclassification of Phaeobacter arcticus and Phaeobacter leonis as Pseudophaeobacter arcticus gen. nov., comb. nov. and Pseudophaeobacter leonis comb. nov., and the reclassification of Phaeobacter aquaemixtae, Phaeobacter caeruleus and Phaeobacter daeponensis as Leisingera aquaemixtae comb. nov., Leisingera caerulea comb. nov. and Leisingera daeponensis comb. nov. The genera Phaeobacter and Leisingera are accordingly emended.

Traditional whistleblowing theories have purported that whistleblowers engage in a rational process in determining whether or not to blow the whistle on misconduct. However, stressors inherent to whistleblowing often impede rational thinking and act as a barrier to effective whistleblowing. The negative impact of these stressors on whistleblowing may be made worse depending on who engages in the misconduct: a peer or advisor. In the present study, participants are presented with an ethical scenario where either a peer or advisor engages in misconduct, and positive and the negative consequences of whistleblowing are either directed to the wrongdoer, department, or university. Participant responses to case questions were evaluated for whistleblowing intentions, moral intensity, metacognitive reasoning strategies, and positive and negative, active and passive emotions. Findings indicate that participants were less likely to report the observed misconduct of an advisor compared to a peer. Furthermore, the findings also suggest that when an advisor is the source of misconduct, greater negative affect results. Post-hoc analyses were also conducted examining the differences between those who did and did not intend to blow the whistle under the circumstances of either having to report an advisor or peer. The implications of these findings for understanding the complexities involved in whistleblowing are discussed.

Analysis of the microbiota of raw cow's milk and semi-finished milk products yielded seven isolates assigned to the genus Pseudomonas that formed two individual groups in a phylogenetic analysis based on partial rpoD and 16S rRNA gene sequences. The two groups could be differentiated from each other and also from their closest relatives as well as from the type species Pseudomonas aeruginosa by phenotypic and chemotaxonomic characterization and average nucleotide identity (ANIb) values calculated from draft genome assemblies. ANIb values within the groups were higher than 97.3 %, whereas similarity values to the closest relatives were 85 % or less. The major cellular lipids of strains WS4917T and WS4993T were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol; the major quinone was Q-9 in both strains, with small amounts of Q-8 in strain WS4917T. The DNA G+C contents of strains WS4917T and WS4993T were 58.08 and 57.30 mol%, respectively. Based on these data, strains WS4917T, WS4995 ( = DSM 29141 = LMG 28434), WS4999, WS5001 and WS5002 should be considered as representatives of a novel species of the genus Pseudomonas, for which the name Pseudomonas helleri sp. nov. is proposed. The type strain of Pseudomonas helleri is strain WS4917T ( = DSM 29165T = LMG 28433T). Strains WS4993T and WS4994 ( = DSM 29140 = LMG 28438) should be recognized as representing a second novel species of the genus Pseudomonas, for which the name Pseudomonas weihenstephanensis sp. nov. is proposed. The type strain of Pseudomonas weihenstephanensis is strain WS4993T ( = DSM 29166T = LMG 28437T).

SunBlock `99 is a Web-based Public Understanding of Science and educational project which seeks to present the very latest solar research as seen through the eyes of young British scientists. These ``solar guides'' discuss not only their scientific interests, but also their extra-curricular activities and the reasons they chose scientific careers; in other words the human face of scientific research. The SunBlock '99 pages gather a range of solar images and movies from current solar space observatories and discuss the underlying physics and its relationship to the school curriculum. The instructional level is pitched at UK secondary school children (aged 13-16 years). It is intended that the material should not only provide a visually appealing introduction to the study of the Sun, but that it should help bridge the often wide gap between classroom science lessons and the research scientist `out in the field'. SunBlock '99 is managed by a team from the Rutherford Appleton Laboratory and the Universities of St Andrews and Cambridge, together with educational consultants. The production has, in part, been sponsored by PPARC and the Millennium Mathematics Project. Web site addresss: http://www.sunblock99.org.uk

Two species of the genus Borrelia , Borrelia bissettiae sp. nov. and Borrelia californiensis sp. nov., were first described by Postic and co-workers on the basis of genetic analyses of several loci. Multilocus sequence analysis of eight housekeeping loci confirmed that these two Borrelia genomospecies are distinct members of the Borrelia burgdorferi sensu lato complex. B. bissettiae sp. nov. was initially described in transmission cycles involving Neotoma fuscipes wood rats and Ixodes pacificus ticks in California, and Neotoma mexicana and Ixodes spinipalpis in Colorado. The preferred host of B. californiensis sp. nov. appears to be the California kangaroo rat, Dipodomys californicus ; Ixodes jellisoni , I. spinipalipis and I. pacificus ticks are naturally infected with it. Thus, the ecological associations of the two genomospecies and their genetic distance from all other known Borrelia genomospecies species justify their description as separate genomospecies: B. bissettiae sp. nov. (type strain DN127 T  = DSM 17990 T  =  CIP 109136 T ) and B. californiensis (type strain CA446 T  = DSM 17989 T  = ATCC BAA-2689 T ).

Spectra of five isolates (LMG 28358 T , LMG 29879 T , LMG 29880 T , LMG 28359 T and R-53705) obtained from gut samples of wild bumblebees of Bombus pascuorum, Bombus lapidarius and Bombus terrestris were grouped into four MALDI-TOF MS clusters. RAPD analysis revealed an identical DNA fingerprint for LMG 28359 T and R-53705 which also grouped in the same MALDI-TOF MS cluster, while different DNA fingerprints were obtained for the other isolates. Comparative 16S rRNA gene sequence analysis of the four different strains identified Gilliamella apicola NCIMB 14804 T as nearest neighbour species. Average nucleotide identity values of draft genome sequences of the four isolates and of G. apicola NCIMB 14804 T were below the 96% threshold value for species delineation and all four strains and G. apicola NCIMB 14804 T were phenotypically distinct. Together, the draft genome sequences and phylogenetic and phenotypic data indicate that the four strains represent four novel Gilliamella species for which we propose the names Gilliamella intestini sp. nov., with LMG 28358 T as the type strain, Gilliamella bombicola sp. nov., with LMG 28359 T as the type strain, Gilliamella bombi sp. nov., with LMG 29879 T as the type strain and Gilliamella mensalis sp. nov., with LMG 29880 T as the type strain.

Hexakis 99m Tc-tertiary butyl isonitrile ( 99m Tc-TBI) was studied as a cardiac perfusion imaging agent in nine dogs with partial occlusion of the LAD. Thirty min after applying the stenosis, 99m Tc-TBI was injected into the right atrium (RA) in five dogs and left atrium (LA) in four dogs. Normal and ischemic zone regional myocardial 99m Tc-TBI activities were monitored continuously for 4 h. Dogs with LA injections had minimal and equivalent 4 h fractional clearance from the normal and ischemic zones. Dogs with RA injections had minimal, but significantly lower 4 h fractional 99m Tc clearances in the ischemic zone (0.08±0.08) compared to the normal zone (0.16±0.07, P 99m Tc-TBI a promising cardiac perfusion imaging agent.

Objective: More studies have found that 99 Tc m -MIBI thyroid imaging may provide more differential diagnostic value than traditional 99 Tc m O 4 - thyroid imaging. This study attempted to analyze the receiver operating characteristic (ROC) curves to verify the additional diagnostic value of 99 Tc m -MIBI over 99 Tc m O 4 - thyroid imaging in the differentiation of the 'cold' nodules. Methods: Sixty-eight patients initially diagnosed with 'cold' nodules in 99 Tc m O 4 - thyroid scintigraphy were selected for further 99 Tc m -MIBI thyroid imaging at early (15 min after 99 Tc m -MIBI intravenous injection, ER) and delayed phase (2 h after injection, DR). Semi-quantitative analysis was performed using tumor/normal tissue (T/N) ratio both at ER and DR, with 0.8 defined as the threshold for differential diagnoses. In ROC curves analyses, the ratios from tumor/submaxillary gland (T/S) and tumor/heart (T/H) were derived to obtain the most proper differential diagnostic thresholds. Results: Of all patients with the 'cold' nodules, only eight cases were finally diagnosed on pathology with thyroid malignancy, while other 60 were benign. For differential diagnoses, the sensitivity, specificity and accuracy of semi-quantitative 99 Tc m -MIBI thyroid imaging were 100.0%, 76.7% and 79.4% respectively. However, with thresholds of T/N=0.995, T/S=0.995, T/H=1.005 derived from ROC curves for DR 99 Tc m -MIBI imaging, the differential diagnostic sensitivities were 100.0%, 87.5%, 75.0% and the specificities were 90.0%, 85.0%, 83.3% respectively. The areas under the ROC curves were 0.949, 0.876 and 0. 867 respectively for DR, all significantly larger than those of ER. Statistical difference was also evident between threshold values of 0.8 and 0.995 (χ 2 =6.125, P 99 Tc m -MIBI thyroid imaging provide additional diagnostic value over 99 Tc m O 4 - thyroid imaging for the differentiation of the 'cold' nodules. For 99 Tc m -MIBI thyroid imaging, DR is more valuable than ER in the ROC

We report results from the first search for ν_{μ}→ν_{e} transitions by the NOvA experiment. In an exposure equivalent to 2.74×10^{20} protons on target in the upgraded NuMI beam at Fermilab, we observe 6 events in the Far Detector, compared to a background expectation of 0.99±0.11(syst) events based on the Near Detector measurement. A secondary analysis observes 11 events with a background of 1.07±0.14(syst). The 3.3σ excess of events observed in the primary analysis disfavors 0.1π<δ_{CP}<0.5π in the inverted mass hierarchy at the 90% C.L.

This study investigates the advantages and disadvantages of three hybrid drive train configurations: series, parallel, and ''through-the-ground'' parallel. Power flow simulations are conducted with the MATLAB/Simulink-based software ADVISOR. These simulations are then applied in an application for the UC Davis SAE Formula Hybrid vehicle. ADVISOR performs simulation calculations for vehicle position using a combined backward/forward method. These simulations are used to study how efficiency and agility are affected by the motor, fuel converter, and hybrid configuration. Three different vehicle models are developed to optimize the drive train of a vehicle for three stages of the SAE Formula Hybrid competition: autocross, endurance, and acceleration. Input cycles are created based on rough estimates of track geometry. The output from these ADVISOR simulations is a series of plots of velocity profile and energy storage State of Charge that provide a good estimate of how the Formula Hybrid vehicle will perform on the given course. The most noticeable discrepancy between the input cycle and the actual velocity profile of the vehicle occurs during deceleration. A weighted ranking system is developed to organize the simulation results and to determine the best drive train configuration for the Formula Hybrid vehicle. Results show that the through-the-ground parallel configuration with front-mounted motors achieves an optimal balance of efficiency, simplicity, and cost. ADVISOR is proven to be a useful tool for vehicle power train design for the SAE Formula Hybrid competition. This vehicle model based on ADVISOR simulation is applicable to various studies concerning performance and efficiency of hybrid drive trains. (author)

An Exploration of the Relationship between International Students and Their Advisors in U.S. Higher Education Institution

International students in U.S. academic settings are facing barriers in the path of their academic accomplishments. In higher educational institutions, students work very closely with their academic advisors to solve a definite problem. Dependence on the academic advisor is much more when the advisee is international. Keeping these points in mind, one of the factors that might impact academic environment for an international student is the bonding that they share with their advisor. This rese...

A novel obligately halophilic, facultatively alkaliphilic actinobacterium, designated EGI 80759T, was isolated from the rhizosphere of Tamarix hispida Willd, Karamay, Xinjiang province, north-west China. Cells of strain EGI 80759T were Gram-stain-positive, non-motile and non-endospore-forming rods. Strain EGI 80759T showed obligately halophilic growth with a tolerance to 8-25 % (w/v) NaCl (optimum growth at 10-12 %, w/v) and facultatively alkaliphilic growth within the pH range 7.0-11.0 (optimum growth at pH 9.0-10.0). Cell-wall hydrolysates of the isolate contained meso-diaminopimelic acid (peptidoglycan type A1γ), with glucose, glucosamine, ribose and mannose as the major sugars. The major fatty acids identified were 10-methyl-C17 : 0, C17 : 1ω8c and C17 : 0. The predominant menaquinone was MK-9(H4). The G+C content of the genomic DNA was 72.1 mol%. Phylogenetic analysis, based on 16S rRNA gene sequences, revealed that strain EGI 80759T clustered with members of the class Nitriliruptoria and showed highest 16S rRNA gene sequence similarities with Euzebya tangerina F10T (90.3 %) and Nitriliruptor alkaliphilus ANL-iso2T (88.1 %). On the basis of the data obtained from phenotypic and chemotaxonomic studies and the phylogenetic analysis, the isolate is proposed to be a representative of a novel genus and a novel species, Egibacter rhizosphaerae gen. nov., sp. nov., of a proposed novel family, Egibacteraceae fam. nov., and order, Egibacterales ord. nov., within the class Nitriliruptoria. The type strain of the type species, Egibacter rhizosphaerae, is EGI 80759T ( = CGMCC 1.14997T = KCTC 39588T).

Full Text Available Two non-pigmented, motile, Gram-negative marine bacteria designated R9SW1T and A3d10T were isolated from sea water samples collected from Chazhma Bay, Gulf of Peter the Great, Sea of Japan, Pacific Ocean, Russia and St. Kilda Beach, Port Phillip Bay, the Tasman Sea, Pacific Ocean, respectively. Both organisms were found to grow between 4 °C and 40 °C, between pH 6 to 9, and are moderately halophilic, tolerating up to 20% (w/v NaCl. Both strains were found to be able to degrade Tween 40 and 80, but only strain R9SW1T was found to be able to degrade starch. The major fatty acids were characteristic for the genus Marinobacter including C16:0, C16:1ω7c, C18:1ω9c and C18:1ω7c. The G+C content of the DNA for strains R9SW1T and A3d10T were determined to be 57.1 mol% and 57.6 mol%, respectively. The two new strains share 97.6% of their 16S rRNA gene sequences, with 82.3% similarity in the average nucleotide identity (ANI, 19.8% similarity in the in silico genome-to-genome distance (GGD, 68.1% similarity in the average amino acid identity (AAI of all conserved protein-coding genes, and 31 of the Karlin's genomic signature dissimilarity. A phylogenetic analysis showed that R9SW1T clusters with M. algicola DG893T sharing 99.40%, and A3d10T clusters with M. sediminum R65T sharing 99.53% of 16S rRNA gene sequence similarities. The results of the genomic and polyphasic taxonomic study, including genomic, genetic, phenotypic, chemotaxonomic and phylogenetic analyses based on the 16S rRNA, gyrB and rpoD gene sequence similarities, the analysis of the protein profiles generated using MALDI-TOF mass spectrometry, and DNA-DNA relatedness data, indicated that strains R9SW1T and A3d10(T represent two novel species of the genus Marinobacter.

The presence of yeasts at different steps of Vietnamese soy paste production was studied. Yeast growth occurred during primary soybean fermentation, with the cell density reaching 4.10 6 c.f.u. ml -1 , and terminated during brine fermentation. The dominant species were Pichia kudriavzevii and Millerozyma farinosa. Over the span of 14 years, nine strains of Moniliella were isolated. The strains had identical PCR fingerprints generated with primer (GAC)5 and identical D1/D2 and internal transcribed spacer (ITS) sequences. A D1/D2-based phylogeny indicated that the strains were closest to a group of four previously assigned as Moniliella suaveolens strains. Together they form a new lineage that is well separated from all known species, including M. suaveolens (over 12.7 % divergence). ITS sequences indicated the presence of four species differing from each other by 9-57 nt. The name Moniliella sojae sp. nov. is proposed to accommodate the strains isolated from Vietnamese soy paste, Moniliella pyrgileucina sp. nov. is proposed for PYCC 6800 and Moniliella casei sp. nov. is proposed for CBS 157.58. An emended combination Moniliella macrospora is proposed for CBS 221.32 and CBS 223.32. The type strains and MycoBank numbers are: M. sojae sp. nov., SS 4.2 T =CBS 126448 T =NRRL Y-48680 T and MB 822871; M. pyrgileucina sp. nov., PYCC 6800 T =CBS 15203 T and MB 823030; M. casei sp. nov., CBS 157.58 T =IFM 60348 T and MB 822872; M. macrospora emend. comb. nov., CBS 221.32 T (=MUCL 11527 T ) and MB 822874.

Are South African financial advisor addressing the estate planning objectives that are important to their client?

Directory of Open Access Journals (Sweden)

Venter, J.M.P.

2014-07-01

Full Text Available Estate planning is an important aspect of any effective financial plan. When preparing an estate plan several objectives identified by the individual planner, as well as several pieces of legislation have to be considered. In South Africa the actions of financial advisors are regulated by the Financial Advisory and Intermediary Services Act. The act aims to ensure that the financial advisor act in the best interest of his / her client. If the act meets its set objectives there will be an alignment of objectives set by a financial advisor and his / her client. This study investigates the existence of an expectation gap between the estate planning objectives considered to be important by the financial advisor and the importance allocated to these factors by the clients. The study found that there was an expectation gap for three of the objectives that should be considered in the estate plan

How do incentives lead to deception in advisors-client interactions? Explicit and implicit strategies of self-interested deception.

Directory of Open Access Journals (Sweden)

Full Text Available When confronted with important questions we like to rely on the advice of experts. However, uncertainty can occur regarding advisors’ motivation to pursue self-interest and deceive the client. This can especially occur when the advisor has the possibility to receive an incentive by recommending a certain alternative. We investigated how the possibility to pursue self-interest led to explicit strategic behavior (bias in recommendation and transfer of information and to implicit strategic behavior (bias in information processing: evaluation and memory. In Study 1 explicit strategic behavior could be identified: Self-interested advisors recommended more often the self-serving alternative and transferred more self-interested biased information to their client compared to the advisor without specific interest. Also deception through implicit strategic behavior was identified: Self-interested advisors biased the evaluation of information less in favor of the client compared to the control group. Self-interested advisors also remembered conflicting information regarding their self-interest worse compared to advisors without self-interest. In Study 2 beside self-interest we assessed accountability which interacted with self-interest and increased the bias: When accountability was high advisor’s self-interest led to higher explicit strategic behavior (less transfer of conflicting information, and to higher implicit strategic behavior (devaluated and remembered less conflicting information. Both studies identified implicit strategic behavior as mediator which can explain the relation between self-interest and explicit strategic behavior. Results of both studies suggest that self-interested advisors use explicit and implicit strategic behavior to receive an incentive. Thus, advisors do not only consciously inform their clients self-interested, but they are influenced unconsciously by biased information processing—a tendency which even increased with

StopAdvisor helped participants with low socioeconomic status stop smoking compared with the information-only website (primary outcome: 90 [8%] of 1088 vs 64 [6%] of 1054 participants; RR 1·36, 95% CI 1·00-1·86; p=0·0499; secondary outcome: 136 [13%] vs 100 [10%] participants; 1·32, 1·03-1·68, p=0·0267), but did not improve cessation rates in those with high socioeconomic status (147 [12%] of 1233 vs 156 [13%] of 1238 participants; 0·95, 0·77-1·17; p=0·61 and 222 [18%] vs 232 [19%] participants; 0·96, 0·81-1·13, p=0·64, respectively). StopAdvisor was more effective than an information-only website in smokers of low, but not high, socioeconomic status. StopAdvisor could be implemented easily and made freely available, which would probably improve the success rates of smokers with low socioeconomic status who are seeking online support.

NOV/CCN3 impairs muscle cell commitment and differentiation

NOV (nephroblastoma overexpressed) is a member of a family of proteins which encodes secreted matrix-associated proteins. NOV is expressed during development in dermomyotome and limb buds, but its functions are still poorly defined. In order to understand the role of NOV in myogenic differentiation, C2C12 cells overexpressing NOV (C2-NOV) were generated. These cells failed to engage into myogenic differentiation, whereas they retained the ability to differentiate into osteoblasts. In differentiating conditions, C2-NOV cells remained proliferative, failed to express differentiation markers and lost their ability to form myotubes. Inhibition of differentiation by NOV was also observed with human primary muscle cells. Further examination of C2-NOV cells revealed a strong downregulation of the myogenic determination genes MyoD and Myf5 and of IGF-II expression. MyoD forced expression in C2-NOV was sufficient to restore differentiation and IGF-II induction whereas 10 -6 M insulin treatment had no effects. NOV therefore acts upstream of MyoD and does not affect IGF-II induction and signaling. HES1, a target of Notch, previously proposed to mediate NOV action, was not implicated in the inhibition of differentiation. We propose that NOV is a specific cell fate regulator in the myogenic lineage, acting negatively on key myogenic genes thus controlling the transition from progenitor cells to myoblasts

Two novel actinomycetes, designated strains 2C-SSA16(2) T and 1C-GS8 T , were isolated from the cuticle of Camponotus japonicus Mayr, collected from Northeast Agricultural University, Heilongjiang Province, north China. Both of them contained genes (involved in antibiotics biosynthesis) of the ketosynthase (KS) and methyl malonyl transferase domains (PKS-I) and the adenylation domain (NRPS). A polyphasic study was carried out to establish the taxonomic positions of these strains. The 16S rRNA gene sequence analysis showed that the two novel isolates 2C-SSA16(2) T and 1C-GS8 T exhibited 98.8% similarity with each other and that they are most closely related to Streptomyces umbrinus JCM 4521 T (99.0, 98.6%), Streptomyces ederensis JCM 4958 T (98.9, 98.7%), Streptomyces aurantiacus JCM 4453 T (98.6, 98.2%), Streptomyces glomeroaurantiacus JCM 4677 T (98.6, 98.1%), Streptomyces tauricus JCM4837 T (98.2, 98.0%) and Streptomyces phaeochromogenes JCM 4070 T (98.2, 99.2%). The corresponding phylogenetic analysis based on partial gyrB gene sequences showed that strains 2C-SSA16(2) T and 1C-GS8 T formed a cluster with the above-mentioned strains. The DNA-DNA hybridization data and phenotypic characteristics indicated that strains 2C-SSA16(2) T and 1C-GS8 T could be readily distinguished from each other and their closest phylogenetic relatives. Therefore, these two strains are suggested to represent two novel species of the genus Streptomyces, for which the names Streptomyces camponoti sp. nov. and Streptomyces cuticulae sp. nov. are proposed. The type strains are 2C-SSA16(2) T (=CGMCC 4.7276 T  = DSM 100522 T ) and 1C-GS8 T (=CGMCC 4.7348 = DSM 103127 T ), respectively.

Nine anamorphic yeast strains isolated from various plant leaves collected in southern China were phylogenetically characterized based on sequences of the internal transcribed spacer (ITS) region, the D1/D2 domains of the large subunit (LSU) rRNA gene, the small subunit (SSU) rRNA gene, the two subunits of the RNA polymerase II gene (RPB1 and RPB2) and the translation elongation factor 1-α (TEF1). Phylogenetic analysis of the combined sequences of the six genes showed that the new strains formed a distinct clade in the class Microbotryomycetes but could not be assigned to any of the existing genera, families or orders of the class. Three separate groups were consistently resolved from the nine new strains based on the combined sequences of the six genes and single gene sequences of ITS, RPB1, RPB2 and TEF1. The results suggest that the nine yeast strains compared represent three novel species in a novel genus. The names Heitmania gen. nov. (MycoBank registration number MB819987), Heitmania litseae sp. nov. (MB820112, type strain CGMCC 2.5697 T =CBS 14756 T ), Heitmania castanopsis sp. nov.

Crop advisors as climate information brokers: Building the capacity of US farmers to adapt to climate change

Directory of Open Access Journals (Sweden)

Maria Carmen Lemos

2014-01-01

Full Text Available This paper examines the role of crop advisors as brokers of climate information to support US corn farmers to adapt to climatic change. It uses quantitative data collected from a broad survey of crop advisors in the US Corn Belt to examine the factors that shape advisors’ use of (and willingness to provide climate information to their clients. Building upon a general model of climate information usability we argue that advisors’ willingness to provide climate advice to farmers is influenced by three main factors: their information seeking habits and behavior, their experience with innovation in the past, and how climate information interplays with other kinds of information that they provide—especially agronomic advice. We find that advisors’ willingness to provide climate related information depends both on factors at the individual and organizational level and on the type of advice they provide. First, at the individual and organizational levels, advisors who work in supportive organizations and who collaborate with other advisors are more likely to provide climate information. Second, advisors are more likely to provide climate information if it does not interfere with their main profit making business (e.g. provision of agronomic advice. Third, there is a significant positive relationship between trust in a greater number or sources of information and use of climate information. Fourth, the way advisors perceive short- and long-term risk also influences their willingness to provide climate information; the more concerned they are about long-term climate-related risks to farming, the more likely they are to provide (or want to provide advice based on climate information. Differently from other empirical work in the literature, our analytical model suggests that neither negative experiences with climate information in the past nor the high level of uncertainty characteristic of climate information appear to influence advisors

An investigation into the technical feasibility of cyclotron production of technetium-99m

International Nuclear Information System (INIS)

Egan, G.F.; Lagunas-Solar, M.C.

1994-01-01

The role of technetium-99m in nuclear medicine is well established with 80 per cent to 90 per cent of all nuclear medicine studies utilising this isotope. Technetium-99m is currently produced from nuclear reactors via production of the parent radionuclide molybdenum-99. The reactor production of 99m Tc has both significant financial and environmental costs, with unresolved problems in the areas of radioactive waste disposal and reactor decommissioning. Recent scientific publications have indicated that medical quality 99m Tc may be produced using cyclotrons without having the associated problems of waste disposal and decommissioning. Further scientific research is now required to demonstrate the feasibility of this cyclotron production technique. A collaboration between the Cyclotron and PET Centre, Austin Hospital, the National Medical Cyclotron, ANSTO, Sydney, and the Crocker Nuclear Laboratory, University of California, Davis, USA has been proposed. The general objective of the proposed collaboration is to acquire additional scientific data to evaluate the 99m Tc cyclotron production method and to determine the feasibility of cyclotron technology for Australian nuclear medicine. 16 refs., 2 tabs

Recently, a taxonomical re-evaluation of the genus Enterobacter, based on multi-locus sequence typing (MLST) analysis, has led to the proposal that the species Enterobacter pulveris, Enterobacter helveticus and Enterobacter turicensis should be reclassified as novel species of the genus Cronobacter. In the present work, new genome-scale analyses, including average nucleotide identity, genome-scale phylogeny and k-mer analysis, coupled with previously reported DNA-DNA hybridization values and biochemical characterization strongly indicate that these three species of the genus Enterobacter are not members of the genus Cronobacter, nor do they belong to the re-evaluated genus Enterobacter. Furthermore, data from this polyphasic study indicated that all three species constitute two new genera. We propose reclassifying Enterobacter pulveris and Enterobacter helveticus in the genus Franconibacter gen. nov. as Franconibacter pulveris comb. nov. (type strain 601/05(T) = LMG 24057(T) = DSM 19144(T)) and Franconibacter helveticus comb. nov. (type strain 513/05(T) = LMG 23732(T) = DSM 18396(T)), respectively, and Enterobacter turicensis in the genus Siccibacter gen. nov. as Siccibacter turicensis comb. nov. (type strain 508/05(T) = LMG 23730(T) = DSM 18397(T)).

The impact of patient advisors on healthcare outcomes: a systematic review

2017-10-01

Full Text Available Abstract Background Patient advisory councils are a way for healthcare organizations to promote patient engagement. Despite mandates to implement patient advisory councils through programs like the Patient-Centered Medical Home (PCMH, there is a paucity of data measuring the impact of patients functioning in advisory roles. Our objective is to investigate whether patient engagement in patient advisory councils is linked to improvements in clinical quality, patient safety or patient satisfaction. Methods We searched PubMed, SCOPUS, CINAHL and Google Scholar for English language publications between November 2002 to August 2015, using a combination of “patient advisor” and “care outcomes” search terms. Article selection utilized dual screening facilitated by DistillerSR software, with group discussion to resolve discordance. Observational studies, randomized controlled trials, and case studies were included that described patients serving in an advisory role where primary outcomes were mentioned. Reference lists of included studies and grey literature searches were conducted. Qualitative thematic analysis was performed to synthesize results. Results Database searching yielded 639 articles total after removing duplicates, with 129 articles meeting full text inclusion criteria. 32 articles were identified for final review, 16 of which were case studies. Advisory roles included patient advisory councils, ad-hoc patient committees, community advisory councils, experience-based co-design, and other. Four practice-based studies from one research group, involving community advisors in the design of public health interventions, found improved clinical outcomes. No prospective experimental studies assessed the impact of patient advisors on patient safety or patient satisfaction. One cluster-randomized RCT showed that patient advisors helped health care planning efforts identify priorities more aligned with the PCMH. Ten case studies reported

Expanding the Use of Time-Based Metering: Multi-Center Traffic Management Advisor

Science.gov (United States)

Landry, Steven J.; Farley, Todd; Hoang, Ty

2005-01-01

Time-based metering is an efficient air traffic management alternative to the more common practice of distance-based metering (or "miles-in-trail spacing"). Despite having demonstrated significant operational benefit to airspace users and service providers, time-based metering is used in the United States for arrivals to just nine airports and is not used at all for non-arrival traffic flows. The Multi-Center Traffic Management Advisor promises to bring time-based metering into the mainstream of air traffic management techniques. Not constrained to operate solely on arrival traffic, Multi-Center Traffic Management Advisor is flexible enough to work in highly congested or heavily partitioned airspace for any and all traffic flows in a region. This broader and more general application of time-based metering is expected to bring the operational benefits of time-based metering to a much wider pool of beneficiaries than is possible with existing technology. It also promises to facilitate more collaborative traffic management on a regional basis. This paper focuses on the operational concept of the Multi-Center Traffic Management Advisor, touching also on its system architecture, field test results, and prospects for near-term deployment to the United States National Airspace System.

Forensic advisors (FA) at the National Institute for Criminalistics and Criminology (NICC), generalists in forensic science, act as an advising body to the magistrate to improve communication between the various parties involved in the investigation: magistrate, police and crime scene investigators, and forensic experts. Their role is manifold, but their main objectives are to optimise trace processing by selecting the most pertinent traces in the context of the case and by advising magistrates on the feasibility of forensic analyses in particular circumstances in regards to the latest technical advances. Despite the absence of a legal framework governing their role and involvement in judicial cases, the demand for their services has increased over the years. Initially, forensic advisors were called for complex homicide cases. Due to the proximity with the Public Prosecutor's Office, the types of offences for which their expertise was sought have become more diverse (mainly including robbery, burglary and sexual assault cases), leading to a diversity in the types of cases handled by the forensic advisors (complex, simple and review). In many of the cases they are requested for, in addition to consulting on the best analytical strategy, forensic advisors also assume the role of case coordinator regarding the seized objects and their respective analyses. Indeed, in the majority of cases treated by the FAs, two or more types of expertise have been requested and performed, either at the internal laboratories of NICC or at external laboratories. This paper explains the role of the forensic advisors in Belgium, the path that let to their current status and problems encountered. Copyright © 2017 The Chartered Society of Forensic Sciences.

Several closely-related, thermophilic, and cellulolytic bacterial strains, designated JKG1T, JKG2, JKG3, JKG4, and JKG5, were isolated from a cellulolytic enrichment (corn stover) incubated in the water column of Great Boiling Spring, NV. Strain JKG1T had cells of a diameter of 0.7 - 0.9 μm and length of ~2.0 μm that formed non-branched multicellular filaments reaching >300 μm. Spores were not formed and dense liquid cultures were red. The temperature range for growth was 45-65 °C, with an optimum of 55 °C. The pH range for growth was 5.6-9.0, with an optimum of 7.5. JKG1T grew as an aerobic heterotroph, utilizing glucose, sucrose, xylose, arabinose, cellobiose, carboxymethylcellulose, filter paper, microcrystalline cellulose, xylan, starch, casamino acids, tryptone, peptone, yeast extract, acetate, citrate, lactate, pyruvate, and glycerol as sole carbon sources, and was not observed to photosynthesize. The cells stained Gram-negative. Phylogenetic analysis using 16S rRNA gene sequences placed the new isolates in the class Chloroflexia, but distant from other cultivated members, with the highest sequence identity of 82.5% to Roseiflexus castenholzii. The major quinone was menaquinone-9; no ubiquinones were detected. The major cellular fatty acids (>5%) were C18:0, anteiso-C17:0, iso-C18:0, and iso-C17:0. C16:0, iso-C16:0, and C17:0. The peptidoglycan amino acids were alanine, ornithine, glutamic acid, serine, and asparagine. Whole-cell sugars included mannose, rhamnose, glucose, galactose, ribose, arabinose, and xylose. Morphological, phylogenetic, and chemotaxonomic results suggest that JKG1T is representative of a new lineage within the class Chloroflexia, which we propose to designate Kallotenue papyrolyticum gen. nov., sp. nov., Kallotenuaceae fam. nov., Kallotenuales ord. nov.

To review the rules, resolutions and existing documents relating to consultant and advisor to better target the actions of those who exercise these roles. The following documents were consulted: Statute of CAPES, through Decree No. 7692 of March 2, 2012; Ordinance No. 47 of 17/10/1995; Opinion 977 1965 Newton Sucupira; Area Document of Medicine III; Interministerial Ordinance 251 of 2012, based on Decree No. 7642 of 2011 of the Ministry of Science and Technology; CAPES Regiment. The Brazilian Postgraduate system is divided in two different fields, according to its aspects: the "lato sensu" postgraduate, defined as all professional studies performed after the high school graduation; and the "stricto sensu" postgraduate that includes the master degree and the doctorate, both of them different from what is known as MSc or MS and PhD. The Brazilian doctorate is recognized as academic because its purposes include to improve the scientific and the teaching levels of university docents. The master degree has two different objectives one is to be academic and similar to the doctorate; the other is to upgrade professionals to a higher level than specialist or MBA and is denominated professional master degree. The master degrees and the doctorate are designated as courses and may be put together in a structure known as stricto sensu postgraduate program. The complexity of these courses and programs in all the areas of the superior human knowledge requires a large number of professional directly involved with this system and other professionals that attend them, called consultants and advisors. The consultants are counselors, and the advisors are assistants, both of them legally established with the incumbency to aid the postgraduate staff in all their duties. Nothing prevents a person from being a consultant on the situation and advisor on another, even in the same institution. Have knowledge about what being a consultant and advisor is required to exercise the function

Science PhD career preferences: levels, changes, and advisor encouragement.

Directory of Open Access Journals (Sweden)

Henry Sauermann

Full Text Available Even though academic research is often viewed as the preferred career path for PhD trained scientists, most U.S. graduates enter careers in industry, government, or "alternative careers." There has been a growing concern that these career patterns reflect fundamental imbalances between the supply of scientists seeking academic positions and the availability of such positions. However, while government statistics provide insights into realized career transitions, there is little systematic data on scientists' career preferences and thus on the degree to which there is a mismatch between observed career paths and scientists' preferences. Moreover, we lack systematic evidence whether career preferences adjust over the course of the PhD training and to what extent advisors exacerbate imbalances by encouraging their students to pursue academic positions. Based on a national survey of PhD students at tier-one U.S. institutions, we provide insights into the career preferences of junior scientists across the life sciences, physics, and chemistry. We also show that the attractiveness of academic careers decreases significantly over the course of the PhD program, despite the fact that advisors strongly encourage academic careers over non-academic careers. Our data provide an empirical basis for common concerns regarding labor market imbalances. Our results also suggest the need for mechanisms that provide PhD applicants with information that allows them to carefully weigh the costs and benefits of pursuing a PhD, as well as for mechanisms that complement the job market advice advisors give to their current students.

Filipino Americans underutilize life-saving screening tests for colorectal cancer, resulting in late stage of diagnosis and poor survival relative to other racial/ethnic groups. Education regarding colorectal cancer screening and distribution of free fecal occult blood test (FOBT) kits are evidence-based interventions that can significantly increase screening. However, this community will only benefit if the intervention is broadly disseminated. We assessed the feasibility of promoting colorectal cancer screening in Filipino American community settings working with community health advisors, and the practicality of conducting one-on-one or small group education, in addition to passing out free FOBT kits. Twenty community health advisors from 4 organizations engaged in recruitment and education activities with 132 participants. Community health advisors consistently completed screening questionnaires to establish eligibility and kept logs of FOBT distribution. However, they did not consistently record eligible participants who did not consent to participate. Process checklists that indicated what information was covered in each educational session and postsession follow-up logs were partially completed. Almost all participants reported receipt of intervention components and receipt of screening at 4-month follow-up and reported high acceptability of the program. The pilot study established the feasibility of working with community health advisors to promote colorectal cancer screening in Filipino American community settings. Findings informed the design of a dissemination trial that is currently ongoing with regards to monitoring recruitment, intervention implementation and follow-up and allowing flexibility regarding one-on-one or small group education.

Strain Jip14(T), a Gram-negative, non-spore-forming, rod-shaped, non-motile bacterium, was isolated from dried rice straw and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain Jip14(T) belongs to the family Sphingobacteriaceae, and the highest degree of sequence similarity was determined to be to Pedobacter saltans DSM 12145(T) (88.5 %), Pedobacter africanus DSM 12126(T) (87.6 %), Pedobacter heparinus DSM 2366(T) (87.1 %) and Pedobacter caeni LMG 22862(T) (86.9 %). Chemotaxonomic data revealed that strain Jip14(T) possesses menaquinone MK-7 and the predominant fatty acids C(15 : 0) iso, C(16 : 0), C(16 : 0) 10-methyl, C(17 : 0) iso 3-OH and summed feature 3 (C(15 : 0) iso 2-OH/C(16 : 1)omega7c). The results of physiological and biochemical tests clearly demonstrated that strain Jip14(T) represents a distinct species. Based on these data, Jip14(T) should be classified within a novel genus and species, for which the name Parapedobacter koreensis gen. nov., sp. nov. is proposed. The type strain of Parapedobacter koreensis is Jip14(T) (=KCTC 12643(T)=LMG 23493(T)).

Intelligent data retrieval in the industry experience advisor expert system

Swisshelm, J.D.

1991-01-01

ABB Impell Corporation developed a prototype expert system called the Industry Experience Advisor for Florida Power and Light Company. This expert system assists plant engineers in evaluating design changes against previous nuclear industry experience. Previous experience is in the form of root causes or lessons learned of past events. The root-cause statements were developed from an engineering review of important event documents [US Nuclear Regulatory Commission information notices (INs) and information bulletins (IBs) and the Institute of Nuclear Power Operations safety evaluation reports and significant operating experience reports]. This paper describes the project that is currently expanding the prototype into a production system for use at a nuclear plant site. The Industry Experience Advisor should be ready for production release by the end of 1991. It will include knowledge of important events through 1990. In 1992 and in each following year, an update will be released adding the previous year's events

A novel myxobacterium, MCy1366(T) (Ar1733), was isolated in 1981 from a soil sample collected from a region near Tokyo, Japan. It displayed general myxobacterial features like Gram-negative-staining, rod-shaped vegetative cells, gliding on solid surfaces, microbial lytic activity, fruiting-body-like aggregates and myxospore-like structures. The strain was mesophilic, aerobic and showed a chemoheterotrophic mode of nutrition. It was resistant to many antibiotics such as cephalosporin C, kanamycin, gentamicin, hygromycin B, polymyxin and bacitracin, and the key fatty acids of whole cell hydrolysates were iso-C15 : 0, iso-C17 : 0 and iso-C17 : 0 2-OH. The genomic DNA G+C content of the novel strain was 65.6 mol%. The 16S rRNA gene sequence showed highest similarity (97.60 %) to 'Stigmatella koreensis' strain KYC-1019 (GenBank accession no. EF112185). Phylogenetic analysis based on 16S rRNA gene sequences and MALDI-TOF MS data revealed a novel branch in the family Myxococcaceae. DNA-DNA hybridization showed only 28 % relatedness between the novel strain and the closest recognized species, Corallococcus exiguus DSM 14696(T) (97 % 16S rRNA gene sequence similarity). A recent isolate from a soil sample collected in Switzerland, MCy10622, displayed 99.9 % 16S rRNA gene sequence similarity with strain MCy1366(T) and showed almost the same characteristics. Since some morphological features like fruiting-body-like aggregates were barely reproducible in the type strain, the newly isolated strain, MCy10622, was also intensively studied. On the basis of a comprehensive taxonomic study, we propose a novel genus and species, Aggregicoccus edonensis gen. nov., sp. nov., for strains MCy1366(T) and MCy10622. The type strain of the type species is MCy1366(T) ( = DSM 27872(T) = NCCB 100468(T)). © 2015 Prof. Dr. Rolf Muller, Department of Pharmaceutical Biotechnology, Saarland University, Campus C2 3, 66123 Saarbrücken, Germany.

Full Text Available In this paper we analyse the main barriers that people with intellectual disabilities who have suffered sexual abuse have to face when they access the Justice system. Regarding these barriers, the Victim Support Unit for People with Intellectual Disabilities of the Fundación Carmen Pardo-Valcarce proposes the inclusion in the judicial process of a helper advisor. The entry into force in 2015 of the Law 4/2015, in 27 April, the Statute of the crime victim represents an exemplary opportunity to ensure the incorporation of support proposals involving the insertion of the helper advisor in the judicial process in cases where the victim is a person with intellectual disabilities. In this paper we analyse the impact of the helper advisor, with particular emphasis on cases that have been dismissed under instruction.

This study aims to identify the criteria used by advisors in the decision-making on whether to accept a candidate for mentoring in a postgraduate strictu sensu program and examines possible relationships between this decision and their scientific production and mentees evasion. In order to meet these goals one seeks to identify and analyze the selection criteria of candidates for the master's and doctorate programs at an institution; in this case, the Energy and Nuclear Research Institute - IPEN. More specifically, one seeks to study similarities and differences between those criteria among the advisors; find out whether there is a correlation between the selection criteria and the advisors characteristics (Profile); identify the selection process used by advisors and point out which are the motivations that lead to evasion according to their point of view. To meet these challenges, as the starting point of the research, a conceptual model was designed in order to form the basis for the preparation of the script for the interviews with open-ended questions as to identify the selection criteria used by a small group of advisors with a predefined profile. From that point, based on the responses obtained in interviews, the survey was expanded to all advisors working in the IPEN Postgraduate program by implementing an online survey using Google Docs app for data collection. These data were then analyzed and reorganized according to an operational model of research that would guide the analysis by structural equation modeling (SEM) by means of the SmartPLS software, in order to identify the presence or absence of correlation between the criteria adopted by the advisors and their academic production and the evasion of their mentees, for that one relied on studies in: Bazerman and Moore (2010); Cohen (1988); Hair Jr. et al (2009); Hansmann and Ringle (2004); Martins (1997); Ringle, C.; Silva and Bido (2014); Sousa (2007); Sousa and Yu (2014); Torres (2014); Yu (2011

A novel actinobacterial strain, designated LPA192(T), was isolated from a soil sample collected from Lop Nur, Xinjiang Uygur Autonomous Region, Northwest China. A polyphasic approach was used to investigate the taxonomic position of strain LPA192(T). The isolate showed morphological and chemotaxonomic characteristics typical of members of the genus Streptomyces. Peptidoglycan was found to contain LL-diaminopimelic acid as the diagnostic diamino acid. The predominant menaquinones were MK-9(H6) and MK-10(H4). Polar lipids were phosphatidylethanolamine, diphosphatidylglycerol and phosphatidylinositol. Major cellular fatty acids consist of C16:0, anteiso-C15:0 and C18:1 ω9c. The sugar in whole-cell hydrolysates was mannose. Phylogenetic analysis indicated that strain LPA192(T) is closely related to Streptomyces tanashiensis LMG 20274(T) (99.3 %), Streptomyces gulbargensis DAS131(T) (99.3 %), Streptomyces nashvillensis NBRC 13064(T) (99.3 %), Streptomyces roseolus NBRC 12816(T) (99.2 %) and Streptomyces filamentosus NBRC 12767(T) (99.1 %) while showing below 98.5 % sequencing similarities with other validly published Streptomyces species. However, DNA-DNA relatedness values between LPA192(T) and the closely related type strains were below 40 %, which are much lower than 70 % threshold value for species delineation. The genomic DNA G + C content of strain LPA192(T) was 69.3 mol %. Based on the differences in genotypic and phenotypic characteristics from the closely related strains, strain LPA192(T) is considered to represent a novel species of the genus Streptomyces for which the name Streptomyces xinjiangensis sp. nov. is proposed. The type strain is LPA192(T) (=KCTC 39601(T) = CGMCC 4.7288(T)).

This report represents the final phase of Swiss Federal Office of Energy project 'Strategy for long-term management of city-owned real estate - the case of the City Council of Chiasso'. It contains a comparative analysis of two tools for the evaluation of the potential for retrofitting and refurbishment of buildings (Retrofit Advisor and Epiqr+). By applying the two tools in parallel, it was possible to compare information and data obtained, and also to obtain indications for the evaluation of the usability of the tools. To achieve this, five buildings in the territory of the city of Chiasso were submitted to the tools for analysis. The applications have highlighted the usability of each case study. The ease of use of Retrofit Advisor has allowed the evaluation of each proposed scenario; by using the same reference system, comparable data are obtained (at indication level) to support the choice of the intervention strategy on existing buildings. In addition to the analysis of the current status, the tool Retrofit Advisor supports a structure analysis over three intervention scenarios, namely reparation, renovation, rebuild. Data entry does not require advanced knowledge of construction work, and is limited to basic characteristics. The analysis performed through Epiqr+ is more rigorous, providing a specific and detailed diagnosis on the state of deterioration of each construction element, supported by a series of intervention suggestions. The Epiqr+ tool has furthermore allowed the evaluation (within a precision range of {+-}15%) the cost of reparation/renovation works, and also the thermal energy balance of each building, based on the characteristics of their envelops. On the basis of contents criteria and cost analysis, the approach has allowed the evaluation of different options for the improvement of the buildings, from simple reparation to total rebuild. Estimates are evaluated in terms of cost, of environmental impact, and, in the case of Retrofit

Verma, Ashish; Mual, Poonam; Mayilraj, Shanmugam; Krishnamurthi, Srinivasan

2015-10-01

Two novel Gram-stain-negative, slow-growing, halotolerant strains with rod-shaped cells, designated as strains Mi-7T and Mi-8, which formed pin-point colonies on halophilic media were isolated during a study into the microbial diversity of a salt pan in the state of Tamilnadu, India. Both the strains had an obligate requirement for 1 % (w/v) NaCl for growth and were halotolerant, growing at NaCl concentrations of up to 20 % (w/v) in media. The strains, however, showed an inability to utilize the majority of substrates tested as sole carbon sources for growth and in fermentation reactions. Molecular phylogenetic analyses, based on 16S rRNA gene sequence revealed their closest phylogenetic neighbours to be members of the genus Marinobacter, with whom they showed the highest sequence similarity of 93.6 % and even less with the type strain of the type species, Marinobacter hydrocarbonoclasticus DSM 8798T (91.1 %). Similarities with other genera within the family Alteromonadaceae were below 91.0 %. However, the two strains were very closely related to each other with 99.9 % sequence similarity, and DNA–DNA hybridization analyses confirmed their placement in the same species. The DNA G+C content of both strains was 65 mol%. Using the polyphasic taxonomic data obtained from this study, strains Mi-7T and Mi-8 represent two strains of the same species of a novel genus for which the name Tamilnaduibacter salinus gen. nov., sp. nov., is proposed; the type strain of the novel species is Mi-7T ( = MTCC 12009T = DSM 28688T).

2017-03-01

Two Gram-stain-variable, non-motile, catalase-positive and cytochrome c oxidase-negative bacteria, designated AK20-18 T and AM20-54, were isolated from forest soil samples collected in the Italian Alps. Growth occurred at a temperature range of 5-30 °C, at pH 6-9 and in the presence of 0-5 % (w/v) NaCl. The 16S rRNA gene sequence similarity between strains AK20-18 T and AM20-54 was 100 %. Phylogenetic analysis based on 16S rRNA gene sequence showed that strain AK20-18 T had highest 16S rRNA gene sequence similarity with the type strain of Arthrobacter psychrochitiniphilus (96.9 %). The cell-wall peptidoglycan structure of strain AK20-18 T was of the type A3alpha l-Lys-l-Thr-l-Ala2 (A11.27). The whole-cell sugars were galactose, ribose and lesser amounts of mannose. The major respiratory quinone of the two strains was menaquinone 9(H2) [MK-9(H2)], whereas MK-10(H2) was a minor component. The polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol and unknown glycolipids. The major cellular fatty acids were anteiso-C15 : 0, iso-C15 : 0, iso-C16 : 0 and anteiso-C17 : 0. The genomic DNA G+C content was 59.9 mol%. Combined data of phylogenetic, phenotypic and chemotaxonomic analyses demonstrated that strains AK20-18 T and AM20-54 represent a novel genus and species, for which the name Psychromicrobium silvestre gen. nov., sp. nov. is proposed. The type strain of Psychromicrobium silvestregen. nov., sp. nov. is AK20-18 T (=DSM 102047 T =LMG 29369 T ).

Slow magnetic monopoles search in NOvA

Antoshkin, Alexander; Frank, Martin

2018-04-01

The NOvA far detector is well suited for finding exotic particles due to its technical features (see [1]). One type of those exotic particles is a "slow" magnetic monopole. It is assumed that the energy deposition of such monopoles should be enough to be registered (see [2]). Measurement of the expected signals was performed on the NOvA test bench at JINR (see [3]). Result of this measurement allows us to perform slow monopole's research using NOvA software and hardware with high efficiency. As a whole, the research can lead to a discovery, or it can limit the existence of monopoles in a wide range of parameters, previously unreachable in other experiments (MACRO, SLIM, RICE, IceCube). Several special software tools have been developed. Slow Monopole Trigger has been created and implemented in the NOvA Data-Driven-Trigger system. Also, an online reconstruction algorithm has been developed and tested on 5% of the data. A technical description of these tools and current results of the analysis are presented in this work.

2005-04-01

Three novel isolates of haloalkaliphilic archaea, strains IHC-005T, IHC-010, and N-1311T, from soda lakes in Inner Mongolia, China, were characterized to elucidate their taxonomic positions. The three strains were aerobic, Gram-negative chemoorganotrophs growing optimally at 37-45 degrees C, pH 9.0-9.5, and 15-20% NaCl. Cells of strains IHC-005T/IHC-010 were motile rods, while those of strain N-1311T were non-motile pleomorphic flats or cocci. The three strains contained diphytanyl and phytanyl-sesterterpanyl diether derivatives of phosphatidylglycerol and phosphatidylglycerophosphate methyl ester. No glycolipids were detected. On phylogenetic analysis of 16S rRNA gene sequences, they formed an independent cluster in the Natro group of the family Halobacteriaceae. Comparison of their morphological, physiological, and biochemical properties, DNA G + C content and 16S rRNA gene sequences, and DNA-DNA hybridization study support the view that strains IHC-005T/IHC-010 and strain N-1311T represent separate species. Therefore, we propose Natronolimnobius baerhuensis gen. nov., sp. nov. for strains IHC-005T (=CGMCC 1.3597T =JCM 12253T)/IHC-010 (=CGMCC 1.3598 = JCM 12254) and Natronolimnobius innermongolicus sp. nov. for N-1311T (=CGMCC 1.2124T =JCM 12255T).

The NOvA software testing framework

International Nuclear Information System (INIS)

Tamsett, M; Group, C

2015-01-01

The NOvA experiment at Fermilab is a long-baseline neutrino experiment designed to study vε appearance in a vμ beam. NOvA has already produced more than one million Monte Carlo and detector generated files amounting to more than 1 PB in size. This data is divided between a number of parallel streams such as far and near detector beam spills, cosmic ray backgrounds, a number of data-driven triggers and over 20 different Monte Carlo configurations. Each of these data streams must be processed through the appropriate steps of the rapidly evolving, multi-tiered, interdependent NOvA software framework. In total there are greater than 12 individual software tiers, each of which performs a different function and can be configured differently depending on the input stream. In order to regularly test and validate that all of these software stages are working correctly NOvA has designed a powerful, modular testing framework that enables detailed validation and benchmarking to be performed in a fast, efficient and accessible way with minimal expert knowledge. The core of this system is a novel series of python modules which wrap, monitor and handle the underlying C++ software framework and then report the results to a slick front-end web-based interface. This interface utilises modern, cross-platform, visualisation libraries to render the test results in a meaningful way. They are fast and flexible, allowing for the easy addition of new tests and datasets. In total upwards of 14 individual streams are regularly tested amounting to over 70 individual software processes, producing over 25 GB of output files. The rigour enforced through this flexible testing framework enables NOvA to rapidly verify configurations, results and software and thus ensure that data is available for physics analysis in a timely and robust manner.

High Energy Neutrino Physics with NOvA

Energy Technology Data Exchange (ETDEWEB)

Coan, Thomas [Southern Methodist Univ. , Dallas, TX (United States)

2016-09-09

Knowledge of the position of energy deposition in “hit” detector cells of the NOvA neutrino detector is required by algorithms for pattern reconstruction and particle identification necessary to interpret the raw data. To increase the accuracy of this process, the majority of NOvA's 350 000 far detector cell shapes, including distortions, were measured as they were constructed. Using a special laser scanning system installed at the site of the NOvA far detector in Ash River, MN, we completed algorithmic development and measured shape parameters for the far detector. The algorithm and the measurements are “published” in NOνA’s document database (doc #10389, “Cell Center Finder for the NOνA Far Detector Modules”).

Morocco has been the subject of very few expeditions on the last century with the objective of studying small cicadas. In the summer of 2014 an expedition was carried out to Morocco to update our knowledge with acoustic recordings and genetic data of these poorly known species. We describe here two new small-sized cicadas that could not be directly assigned to any species of North African cicadas: Tettigettalna afroamissa sp. nov. and Berberigetta dimelodica gen. nov. & sp. nov. In respect to T. afroamissa it is the first species of the genus to be found outside Europe and we frame this taxon within the evolutionary history of the genus. Acoustic analysis of this species allows us to confidently separate T. afroamissa from its congeners. With B. dimelodica, a small species showing a remarkable calling song characterized by an abrupt frequency modulation, a new genus had to be erected. Bayesian inference and maximum likelihood phylogenetic analyses with DNA-barcode sequences of Cytochrome C Oxidase 1 support the monophyly of both species, their distinctness and revealed genetic structure within B. dimelodica. Alongside the descriptions we also provide GPS coordinates of collection points, distributions and habitat preferences.

Corynebacterium pilbarense sp. nov., a non-lipophilic corynebacterium isolated from a human ankle aspirate.

Science.gov (United States)

Aravena-Roman, M; Spröer, C; Sträubler, B; Inglis, T; Yassin, A F

2010-07-01

A non-lipophilic coryneform bacterium isolated from an anaerobic Bactec bottle inoculated with an ankle aspirate from a male patient was characterized by phenotypic and molecular taxonomic methods. Chemotaxonomic investigations revealed the presence of short-chain mycolic acids in the cell wall of the bacterium, a feature consistent with members of the genus Corynebacterium. Comparative 16S rRNA gene sequence analysis demonstrated that the isolate displayed 92.0-99.0 % gene sequence similarity with members of the genus Corynebacterium, with Corynebacterium ureicelerivorans as the most closely related phylogenetic species (99.0 % gene sequence similarity). However, the isolate could be genomically separated from C. ureicelerivorans on the basis of DNA-DNA hybridization studies (39.5 % relatedness). Furthermore, the isolate could also be differentiated from C. ureicelerivorans and other species of the genus Corynebacterium on the basis of biochemical properties. Based on both phenotypic and phylogenetic evidence, it is proposed that this isolate be classified as representing a novel species, Corynebacterium pilbarense sp. nov. (type strain IMMIB WACC 658(T)=DSM 45350(T)=CCUG 57942(T)).

Saker, Rafika; Bouras, Noureddine; Meklat, Atika; Zitouni, Abdelghani; Schumann, Peter; Spröer, Cathrin; Klenk, Hans-Peter; Sabaou, Nasserdine

2015-03-01

A novel halophilic, filamentous actinomycete, designated H254(T), was isolated from a Saharan soil sample collected from Biskra (Northern Sahara), and subjected to a polyphasic taxonomic characterization. The strain is Gram-positive, aerobic, and halophilic, and the optimum NaCl concentration for growth is 15-20 % (w/v). The cell-wall hydrolysate contained meso-diaminopimelic acid, and the diagnostic whole-cell sugars were arabinose and galactose. The diagnostic phospholipid detected was phosphatidylcholine, and MK-9(H4) was the predominant menaquinone. The major fatty acid profiles were anteiso-C17:0 (32.8 %), C15:0 (28 %), and iso-C17:0 (12.3 %). Comparative analysis of the 16S rRNA gene sequences revealed that the strain H254(T) formed a well-separated sub-branch within the radiation of the genus Actinopolyspora, and the microorganism was most closely related to Actinopolyspora saharensis DSM 45459(T) (99.2 %), Actinopolyspora halophila DSM 43834(T) (99.1 %), and Actinopolyspora algeriensis DSM 45476(T) (99.0 %). Nevertheless, the strain had relatively lower mean values for DNA-DNA relatedness with the above strains (57.2, 68.4, and 45.6 %, respectively). Based on phenotypic features and phylogenetic position, we propose that strain H254(T) represents a novel species of the genus Actinopolyspora, for which the name Actinopolyspora biskrensis sp. nov. is proposed. The type strain of A. biskrensis is strain H254(T) (=DSM 46684(T) =CECT 8576(T)).

Jung, Yoon

2016-01-01

Spot and Runway Departure Advisor (SARDA) is a decision support tool to assist airline ramp controllers and ATC tower controllers to manage traffic on the airport surface to significantly improve efficiency and predictability in surface operations. The core function of the tool is the runway scheduler which generates an optimal solution for runway sequence and schedule of departure aircraft, which would minimize system delay and maximize runway throughput. The presentation also discusses the latest status of NASA's current surface research through a collaboration with an airline partner, where a tool is developed for airline ramp operators to assist departure pushback operations. The presentation describes the concept of the SARDA tool and results from human-in-the-loop simulations conducted in 2012 for Dallas-Ft. Worth International Airport and 2014 for Charlotte airport ramp tower.

2016-02-01

Two isolates of aerobic, budding, pink-pigmented bacteria, designated strains PX4 T and PT1, were isolated from a boreal Sphagnum peat bog and a forested tundra wetland. Cells of these strains were non-motile spheres that occurred singly or in short chains. Novel isolates were capable of growth at pH values between 3.5 and 6.5 (optimum at pH 5.0-5.5) and at temperatures between 6 and 30 °C (optimum at 15-25 °C). Most sugars and a number of polysaccharides including pectin, xylan, lichenin and Phytagel were used as growth substrates. The major fatty acids were C 16 : 0 , C 18 : 1 ω9 and C 18 : 0 ; the major polar lipids were phosphocholine and trimethylornithine. The quinone was menaquinone-6, and the G+C content of the DNA was 66 mol%. Strains PX4 T and PT1 were members of the order Planctomycetales and displayed 93-94 % 16S rRNA gene sequence similarity to Aquisphaera giovannonii , 91-92 % to species of the genus Singulisphaera and 90-91 % to Isosphaera pallida . The two novel strains, however, differed from members of these genera by cell morphology, substrate utilization pattern and a number of physiological characteristics. Based on these data, the novel isolates should be considered as representing a novel genus and species of planctomycetes, for which the name Paludisphaera borealis gen. nov., sp. nov., is proposed. The type strain is PX4 T ( = DSM 28747 T  = VKM B-2904 T ). We also suggest the establishment of a novel family, Isosphaeraceae fam. nov., to accommodate stalk-free planctomycetes with spherical cells, which can be assembled in short chains, long filaments or shapeless aggregates. This family includes the genera Isosphaera, Aquisphaera, Singulisphaera and Paludisphaera .

The Spot and Runway Departure Advisor (SARDA) is a research prototype of a decision support tool for ATC tower controllers to assist in manging and controlling traffic on the surface of an airport. SARDA employs a scheduler to generate an optimal runway schedule and gate push-back - spot release sequence and schedule that improves efficiency of surface operations. The advisories for ATC tower controllers are displayed on an Electronic Flight Strip (EFS) system. The human-in-the-loop simulation of the SARDA tool was conducted for east operations of Dallas-Ft. Worth International Airport (DFW) to evaluate performance of the SARDA tool and human factors, such as situational awareness and workload. The results indicates noticeable taxi delay reduction and fuel savings by using the SARDA tool. Reduction in controller workload were also observed throughout the scenario runs. The future plan includes modeling and simulation of the ramp operations of the Charlotte International Airport, and develop a decision support tool for the ramp controllers.

99Tc atom counting by quadrupole ICP-MS. Optimisation of the instrumental response

International Nuclear Information System (INIS)

Mas, Jose L.; Garcia-Leon, Manuel; Bolivar, Juan P.

2002-01-01

In this paper, an extensive work is done on the specific tune of a conventional ICP-MS for 99 Tc atom counting. For this, two methods have been used and compared: the partial variable control method and the 5D Simplex method. Instrumental limits of detection of 0.2 and 0.8 ppt, respectively, were obtained. They are noticeably lower than that found with the automatic tune method of the spectrometer, 47 ppt, which shows the need of a specific tune when very low levels of 99 Tc have to be determined. A study is presented on the mass interferences for 99 Tc. Our experiments show that the formation of polyatomic atoms or refractory oxides as well as 98 Mo hydrides seem to be irrelevant for 99 Tc atom counting. The opposite occurs with the presence of isobaric interferences, i.e. 99 Ru, and the effect of abundance sensitivity, or low-mass resolution, which can modify the response at m/z=99 to a non-negligible extent

The HEPCloud Facility: elastic computing for High Energy Physics - The NOvA Use Case

Science.gov (United States)

Fuess, S.; Garzoglio, G.; Holzman, B.; Kennedy, R.; Norman, A.; Timm, S.; Tiradani, A.

2017-10-01

The need for computing in the HEP community follows cycles of peaks and valleys mainly driven by conference dates, accelerator shutdown, holiday schedules, and other factors. Because of this, the classical method of provisioning these resources at providing facilities has drawbacks such as potential overprovisioning. As the appetite for computing increases, however, so does the need to maximize cost efficiency by developing a model for dynamically provisioning resources only when needed. To address this issue, the HEPCloud project was launched by the Fermilab Scientific Computing Division in June 2015. Its goal is to develop a facility that provides a common interface to a variety of resources, including local clusters, grids, high performance computers, and community and commercial Clouds. Initially targeted experiments include CMS and NOvA, as well as other Fermilab stakeholders. In its first phase, the project has demonstrated the use of the “elastic” provisioning model offered by commercial clouds, such as Amazon Web Services. In this model, resources are rented and provisioned automatically over the Internet upon request. In January 2016, the project demonstrated the ability to increase the total amount of global CMS resources by 58,000 cores from 150,000 cores - a 38 percent increase - in preparation for the Recontres de Moriond. In March 2016, the NOvA experiment has also demonstrated resource burst capabilities with an additional 7,300 cores, achieving a scale almost four times as large as the local allocated resources and utilizing the local AWS s3 storage to optimize data handling operations and costs. NOvA was using the same familiar services used for local computations, such as data handling and job submission, in preparation for the Neutrino 2016 conference. In both cases, the cost was contained by the use of the Amazon Spot Instance Market and the Decision Engine, a HEPCloud component that aims at minimizing cost and job interruption. This paper

Two strains of subdivision 1 Acidobacteria, a pink-pigmented bacterium KA1(T) and a colourless isolate WH120(T), were obtained from acidic Sphagnum peat and wood under decay by the white-rot fungus Hyploma fasciculare, respectively. Cells of these isolates were Gram-negative-staining, non-motile, short rods, which were covered by large polysaccharide capsules and occurred singly, in pairs, or in short chains. Strains KA1(T) and WH120(T) were strictly aerobic mesophiles that grew between 10 and 33 °C, with an optimum at 22-28 °C. Both isolates developed under acidic conditions, but strain WH120(T) was more acidophilic (pH growth range 3.5-6.4; optimum, 4.0-4.5) than strain KA1(T) (pH growth range 3.5-7.3; optimum , 5.0-5.5). The preferred growth substrates were sugars. In addition, the wood-derived isolate WH120(T) grew on oxalate, lactate and xylan, while the peat-inhabiting acidobacterium strain KA1(T) utilized galacturonate, glucuronate and pectin. The major fatty acids were iso-C(15:0) and iso-C(17:1)ω8c; the cells also contained significant amounts of 13,16-dimethyl octacosanedioic acid. The quinone was MK-8. The DNA G+C contents of strains KA1(T) and WH120(T) were 54.1 and 51.7 mol%, respectively. Strains KA1(T) and WH120(T) displayed 97.8% 16S rRNA gene sequence similarity to each other. The closest recognized relatives were Acidobacterium capsulatum and Telmatobacter bradus (93.4-94.3% 16S rRNA gene sequence similarity). These species differed from strains KA1(T) and WH120(T) by their ability to grow under anoxic conditions, the absence of capsules, presence of cell motility and differing fatty acid composition. Based on these differences, the two new isolates are proposed as representing a novel genus, Acidicapsa gen. nov., and two novel species. Acidicapsa borealis gen. nov., sp. nov. is the type species for the new genus with strain KA1(T) (=DSM 23886(T)=LMG 25897(T)=VKM B-2678(T)) as the type strain. The name Acidicapsa ligni sp. nov. is proposed for

The morphology of three marine colepid ciliates, Nolandia sinica spec. nov., Apocoleps caoi spec. nov. and Tiarina fusa (Claparède & Lachmann, 1858) Bergh, 1881, isolated from Chinese coastal waters, was investigated. N. sinica spec. nov. may be separated from its congeners by the structure of its armour plates, each of which may have up to five reniform windows. A. caoi spec. nov. is characterized by its large body with broad anterior end and by having 10-12 long, sharp posterior spines. New data and an improved diagnosis are supplied for Tiarina fusa (Claparède & Lachmann, 1858) Bergh, 1881, which has a spindle-shaped body, about 16 ciliary rows and a single adoral organelle. Sequence similarities with other available colepid species were determined.

Technetium-99m ( 99m Tc) is the most widely used radioisotope in nuclear medicine. It accounts for more than 80% of the total demand for radioisotopes. Alone or conjugated with other ligands, it is very useful in the imaging and scanning of various organs such as the brain, lungs, kidneys, liver, thyroid and bone and in the diagnosis of metabolic disorders. It is imported to the country as 99 Mo- 99m Tc generators. These commercial generators use fission molybdenum adsorbed onto alumina column. A Draft Business Plan for the Production of PZC 99 Mo- 99m Tc Generator in the Philippines was presented during the FNCA 2005 Workshop on the Utilization of Research Reactors, August 08-12, 2005. The Philippine Nuclear Research Institute (PNRI) proposed in the draft business plan, the commercial production of PZC generator through the establishment of a facility for the in-house production of 99 Mo- 99m Tc generators. The radioisotope laboratory of the Irradiation Services Unit will be renovated to house the PZC based 99 Mo- 99m Tc generator experiment/production facility. Since the research reactor is on extended shutdown, the supply of 99 Mo will be sourced out from neighboring countries. Information dissemination and promotions will be made in order to bring this PZC based 99 Mo- 99m Tc generator to the nuclear medicine users. (author)

Two Lactobacillus strains, designated LY-73(T) and LY-30B, were isolated from a dairy beverage, sold in Shenzhen market, China. The two isolates were Gram-positive, non-spore-forming, non-motile, facultatively anaerobic rods that were heterofermentative and did not exhibit catalase activity. Sequencing of the 16S rRNA, pheS and rpoA genes revealed that the two isolates shared 99.5, 99.8 and 99.9 % sequence similarity, which indicates that they belong to the same species. Phylogenetic analysis demonstrated clustering of the two isolates with the genus Lactobacillus. Strain LY-73(T) showed highest 16S rRNA gene sequence similarities with Lactobacillus harbinensis KACC 12409(T) (97.73%), Lactobacillus perolens DSM 12744(T) (96.96 %) and Lactobacillus selangorensis DSM 13344(T) (93.10 %). Comparative analyses of their rpoA and pheS gene sequences indicated that the novel strains were significantly different from other Lactobacillus species. Low DNA-DNA reassociation values (50.5 %) were obtained between strain LY-73(T) and its phylogenetically closest neighbours. The G+C contents of the DNA of the two novel isolates were 56.1 and 56.5 mol%. Straight-chain unsaturated fatty acids C18 : 1ω9c (78.85 and 74.29 %) were the dominant components, and the cell-wall peptidoglycan was of the l-Lys-d-Asp type. Based on phenotypic characteristics, and chemotaxonomic and genotypic data, the novel strains represent a novel species of the genus Lactobacillus, for which the name Lactobacillus shenzhenensis sp. nov. is proposed, with LY-73(T) ( = CCTCC M 2011481(T) = KACC 16878(T)) as the type strain.

Three strains of regular, long, Gram-stain-positive bacterial rods were isolated using TPY, M.R.S. and Rogosa agar under anaerobic conditions from the digestive tract of wild mice (Mus musculus). All 16S rRNA gene sequences of these isolates were most similar to sequences of Lactobacillus gasseri ATCC 33323T and Lactobacillus johnsonii ATCC 33200T (97.3% and 97.2% sequence similarities, respectively). The novel strains shared 99.2-99.6% 16S rRNA gene sequence similarities. Type strains of L. gasseri and L. johnsonii were also most related to the newly isolated strains according to rpoA (83.9-84.0% similarities), pheS (84.6-87.8%), atpA (86.2-87.7%), hsp60 (89.4-90.4%) and tuf (92.7-93.6%) gene sequence similarities. Phylogenetic studies based on 16S rRNA, hsp60, rpoA, atpA and pheS gene sequences, other genotypic and many phenotypic characteristics (results of API 50 CHL, Rapid ID 32A and API ZYM biochemical tests; cellular fatty acid profiles; cellular polar lipid profiles; end products of glucose fermentation) showed that these bacterial strains represent a novel species within the genus Lactobacillus. The name Lactobacillus rodentium sp. nov. is proposed to accommodate this group of new isolates. The type strain is MYMRS/TLU1T (=DSM 24759T=CCM 7945T).

Labilibaculum manganireducens gen. nov., sp. nov. and Labilibaculum filiforme sp. nov., Novel Bacteroidetes Isolated from Subsurface Sediments of the Baltic Sea

Full Text Available Microbial communities in deep subsurface sediments are challenged by the decrease in amount and quality of organic substrates with depth. In sediments of the Baltic Sea, they might additionally have to cope with an increase in salinity from ions that have diffused downward from the overlying water during the last 9000 years. Here, we report the isolation and characterization of four novel bacteria of the Bacteroidetes from depths of 14–52 m below seafloor (mbsf of Baltic Sea sediments sampled during International Ocean Discovery Program (IODP Expedition 347. Based on physiological, chemotaxonomic and genotypic characterization, we propose that the four strains represent two new species within a new genus in the family Marinifilaceae, with the proposed names Labilibaculum manganireducens gen. nov., sp. nov. (type strain 59.10-2MT and Labilibaculum filiforme sp. nov. (type strains 59.16BT with additional strains of this species (59.10-1M and 60.6M. The draft genomes of the two type strains had sizes of 5.2 and 5.3 Mb and reflected the major physiological capabilities. The strains showed gliding motility, were psychrotolerant, neutrophilic and halotolerant. Growth by fermentation of mono- and disaccharides as well as pyruvate, lactate and glycerol was observed. During glucose fermentation, small amounts of electron equivalents were transferred to Fe(III by all strains, while one of the strains also reduced Mn(IV. Thereby, the four strains broaden the phylogenetic range of prokaryotes known to reduce metals to the group of Bacteroidetes. Halotolerance and metal reduction might both be beneficial for survival in deep subsurface sediments of the Baltic Sea.

Three strains of Gram-staining-positive, coccus-shaped, lactic acid bacteria, designated as HibF3 T , HibF2 and HibF5 were isolated from fresh flowers of hibiscus, and a fourth, DF1 T , was isolated from fresh flowers of durian tree, in Penang, Malaysia. Taxonomic characterisation was performed by polyphasic analysis. Sequence similarities of the 16S rRNA gene and the housekeeping rpoA and pheS genes of these strains with their closely-related lactococcal and streptococcal relatives were 92-94, 78 and 81 %, respectively. The results of phylogenetic analysis indicated that strains DF1 T , HibF2, HibF5 and HibF3 T were clustered together but were clearly separated from species of the genera Streptococcus and Lactococcus, indicating that they represent members of a novel genus of the family Streptococcaceae. Calculation of average nucleotide identity (ANI) values between the genomes of DF1 T and HibF3 T yielded values of 92.50-92.93 %. ANI values below the cut-off value and distinctive chemotaxonomic characteristics supported the hypothesis that these strains represented two novel species. Major cellular fatty acids in DF1 T , HibF2 and HibF5 were C18 : 1ω7c and C16 : 0, while C12 : 0 and C14 : 0 were also dominant, in addition to C18 : 1ω7c and C16 : 0, in HibF3 T . A novel genus is proposed with the name Floricoccus gen. nov. which consists of two species, Floricoccus tropicus sp. nov as the type species, and Floricoccus penangensis sp. nov. The respective type strains are DF1 T (=LMG 29833 T =JCM 31733 T ) and HibF3 T (=LMG 29831 T =DSM 31735 T ).

Strains Y-12(T) and Y-47(T) were isolated from mountain forest soil and strain WR43(T) was isolated from rhizosphere soil, at Daejeon, Korea. The three strains grew at 10-55 °C (optimal growth at 28-30 °C), at pH 3.0-8.0 (optimal growth at pH 6.0) and in the presence of 0-4.0% (w/v) NaCl, growing optimally in the absence of added NaCl. On the basis of 16S rRNA gene sequence analysis, the three strains were found to belong to the genus Burkholderia, showing the closest phylogenetic similarity to Burkholderia diazotrophica JPY461(T) (97.2-97.7%); the similarity between the three sequences ranged from 98.3 to 98.7%. Additionally, the three strains formed a distinct group in phylogenetic trees based on the housekeeping genes recA and gyrB. The predominant ubiquinone was Q-8, the major fatty acids were C16 : 0 and C17  : 0 cyclo and the DNA G+C content of the novel isolates was 61.6-64.4 mol%. DNA-DNA relatedness among the three strains and the type strains of the closest species of the genus Burkholderia was less than 50%. On the basis of 16S rRNA, recA and gyrB gene sequence similarities, chemotaxonomic and phenotypic data, the three strains represent three novel species within the genus Burkholderia, for which the names Burkholderia humisilvae sp. nov. (type strain Y-12(T)= KACC 17601(T) = NBRC 109933(T) = NCAIM B 02543(T)), Burkholderia solisilvae sp. nov. (type strain Y-47(T) = KACC 17602(T)= NBRC 109934(T) = NCAIM B 02539(T)) and Burkholderia rhizosphaerae sp. nov. (type strain WR43(T) = KACC 17603(T) = NBRC 109935(T) = NCAIM B 02541(T)) are proposed.

The HEPCloud Facility: elastic computing for High Energy Physics – The NOvA Use Case

The need for computing in the HEP community follows cycles of peaks and valleys mainly driven by conference dates, accelerator shutdown, holiday schedules, and other factors. Because of this, the classical method of provisioning these resources at providing facilities has drawbacks such as potential overprovisioning. As the appetite for computing increases, however, so does the need to maximize cost efficiency by developing a model for dynamically provisioning resources only when needed. To address this issue, the HEPCloud project was launched by the Fermilab Scientific Computing Division in June 2015. Its goal is to develop a facility that provides a common interface to a variety of resources, including local clusters, grids, high performance computers, and community and commercial Clouds. Initially targeted experiments include CMS and NOvA, as well as other Fermilab stakeholders. In its first phase, the project has demonstrated the use of the “elastic” provisioning model offered by commercial clouds, such as Amazon Web Services. In this model, resources are rented and provisioned automatically over the Internet upon request. In January 2016, the project demonstrated the ability to increase the total amount of global CMS resources by 58,000 cores from 150,000 cores - a 25 percent increase - in preparation for the Recontres de Moriond. In March 2016, the NOvA experiment has also demonstrated resource burst capabilities with an additional 7,300 cores, achieving a scale almost four times as large as the local allocated resources and utilizing the local AWS s3 storage to optimize data handling operations and costs. NOvA was using the same familiar services used for local computations, such as data handling and job submission, in preparation for the Neutrino 2016 conference. In both cases, the cost was contained by the use of the Amazon Spot Instance Market and the Decision Engine, a HEPCloud component that aims at minimizing cost and job interruption. This paper

Gram-stain-positive, rod-shaped, non-spore forming bacteria have been isolated from flowers and the guts of adult wild bees in the families Megachilidae and Halictidae. Phylogenetic analysis of the 16S rRNA gene indicated that these bacteria belong to the genus Lactobacillus, and are most closely related to the honey-bee associated bacteria Lactobacillus kunkeei (97.0 % sequence similarity) and Lactobacillus apinorum (97.0 % sequence similarity). Phylogenetic analyses of 16S rRNA genes and six single-copy protein coding genes, in situ and in silico DNA-DNA hybridization, and fatty-acid profiling differentiates the newly isolated bacteria as three novel Lactobacillus species: Lactobacillus micheneri sp. nov. with the type strain Hlig3 T (=DSM 104126 T ,=NRRL B-65473 T ), Lactobacillus timberlakei with the type strain HV_12 T (=DSM 104128 T ,=NRRL B-65472 T ), and Lactobacillus quenuiae sp. nov. with the type strain HV_6 T (=DSM 104127 T ,=NRRL B-65474 T ).

Six Gram-positive, non-motile, UV- and draught-tolerant bacteria were isolated from antarctic soil and rock samples. The pink to orange cocci grew well on oligotrophic medium PYGV (pH 7.5) at 9-18 degrees C. They tolerated 0-10% NaCl, were aerobic to facultatively anaerobic and contained ornithine in their cell wall (type A3beta, Orn-Gly2). The lipid profiles of four strains were found to be typical for those of D. radiodurans. Major fatty acids were 16:1cis9, 15:1cis9, 17:1cis9 and i17:1cis9, the respiratory quinone of three strains was MK-8. Comparative 16S rDNA gene sequencing revealed phylogenetic relationships to the Deinococcus clade, especially to D. radiopugnans. The levels of 16S rRNA gene sequence similarity and DNA-DNA hybridisation data showed the six isolates represented new taxa. Phenotypic properties supported the description of three new species which were different from the eight known Deinococcus species and particularly from D. radiopugnans. Soil isolate AA-692T (DSM 12807T) is the type strain of Deinococcus frigens sp. nov., with AA-752 (DSM 15993) and AA-829 (DSM 15994) as additional strains from soil. The endolithic isolate AA-1444T, Deinococcus saxicola sp. nov., (DSM 15974T) came from antarctic sandstone, and Deinococcus marmoris sp. nov. (isolate AA-63T [DSM 12784T]) as well as AA-69 (DSM 15951) were isolated from antarctic marble.

Introduction: The use of 99m Tc-macroggregated albumin for lung perfusion imaging is well established in nuclear medicine. However, there have been safety concerns over the use of blood-derived products because of potential contamination by infective agents, for example, Variant Creutzfeldt Jakob Disease. Preliminary work has indicated that Tc(CO) 5 I is primarily taken up in the lungs following intravenous administration. The aim of this study was to evaluate the biodistribution and pharmacokinetics of 99m Tc(CO) 5 I and its potential as a lung perfusion agent. Methods: 99m Tc(CO) 5 I was synthesized by carbonylation of 99m TcO 4- at 160 atm of CO at 170 deg. C in the presence of HI for 40 min. Radiochemical purity was determined by HPLC using 99 Tc(CO) 5 I as a reference. 99m Tc(CO) 5 I was administered by ear-vein injection to three chinchilla rabbits, and dynamic images were acquired using a gamma camera (Siemens E-cam) over 20 min. Imaging studies were also performed with 99m Tc-labeled macroaggregated albumin ( 99m Tc-MAA) and 99m TcO 4- for comparison. 99m Tc(CO) 5 I was administered intravenously to Sprague-Dawley rats, and tissue distribution studies were obtained at 15 min and 1 h postinjection. Comparative studies were performed using 99m Tc-MAA. Results: Radiochemical purity, assessed by HPLC, was 98%. The retention time was similar to that of 99 Tc(CO) 5 I. The dynamic images showed that 70% of 99m Tc(CO) 5 I appeared promptly in the lungs and remained constant for at least 20 min. In contrast, 99m TcO 4- rapidly washed out of the lungs after administration. As expected 99m Tc-MAA showed 90% lung accumulation. The percentage of injected dose per gram of organ ±S.D. at 1 h for 99m Tc(CO) 5 I was as follows: blood, 0.22±0.02; lung, 12.8±2.87; liver, 0.8±0.15; heart, 0.15±0.01; kidney, 0.47±0.08. The percentage of injected dose per organ ±S.D. at 1 h was as follows: lung, 22.47±2.31; liver, 10.53±1.8; heart, 0.18±0.01; kidney, 1.2±0.17. Tissue

Morphological, anatomical, and molecular sequence data were used to assess the establishment and phylogenetic position of the genus Wilsonosiphonia gen. nov. Phylogenies based on rbcL and concatenated rbcL and cox1 loci support recognition of Wilsonosiphonia gen. nov., sister to Herposiphonia. Diagnostic features for Wilsonosiphonia are rhizoids located at distal ends of pericentral cells and taproot-shaped multicellular tips of rhizoids. Wilsonosiphonia includes three species with diagnostic rbcL and cox1 sequences, Wilsonosiphonia fujiae sp. nov. (the generitype), W. howei comb. nov., and W. indica sp. nov. These three species resemble each other in external morphology, but W. fujiae is distinguished by having two tetrasporangia per segment rather than one, W. indica by having abundant and persistent trichoblasts, and W. howei by having few and deciduous trichoblasts. © 2017 Phycological Society of America.

In this note we perform a cross check of the programs used by NOvA to calculate the 3-flavor oscillation probabilities with a independent program using a different method. The comparison is performed at 6 significant figures and the agreement, $|\\Delta P|/P$ is better than $10^{-5}$, as good as can be expected with 6 significant figures. In addition, a simple and accurate alternative method to calculate the oscillation probabilities is outlined and compared in the L/E range and matter density relevant for the NOvA experiment.

This study aimed to evaluate if the splenectomy alters the biodistribution of 99mTc-DMSA and renal function in Wistar rats. The animals were separated in the groups: splenectomy (n = 6) and control (n = 6). After splenectomy (15 days), the administration of 0.1 ml of 99mTc-DMSA IV (0.48 MBq) was carried out. Thirty minutes later, kidney, heart, lung, thyroid, stomach, bladder and femur and samples of blood were isolated. The organs were weighed, counted and the percentage of radioactivity /g (%ATI/g) determined. Serum urea and creatinine, hematocrit, leukocytes and platelets were measured. Statistics by t test (p<0.05) was done. There was a significant reduction in %ATI/g in kidney and blood (p<0.05) of splenectomized animals, a significant increase (p<0.05) of urea (88.8 ± 18.6 mg/dL) and creatinine (0.56 ± 0.08 mg/dL), compared to the controls (51.5±1.6, 0.37±0.02 mg/dL, respectively), as well as increase in platelets and leucocytes, and hematocrit reduction. The analysis of the results indicates that in rats, splenectomy seems to alter the renal function and the uptake of 99mTc-DMSA. (author)

Objective: To compare the results of 99 Tc m -tetrofosmin (TF) and 99 Tc m -MIBI G-MPI in evaluating left ventricular myocardial perfusion and other functional parameters. Methods: TF and MIBI were both labeled by 99 Tc m and the radiochemical purities were tested. During December 2011 to May 2012, 112 patients who had examinations of CAG and echocardiograph in one week after G-MPI were divided into 99 Tc m -TF group (47 patients) and 99 Tc m -MIBI group (65 patients) by simple random sampling. Patients who suffered from severe arrhythmia, clinically suspicious of myocarditis or cardiomyopathy were excluded. The research was approved by the ethics committee, and all patients signed informed consents. One-day 99 Tc m -TF G-MPI and two-day 99 Tc m -MIBI G-MPI were performed. The left ventricular functional parameters were acquired automatically by Cedars quantitative gated SPECT (QGS) software, including LVEF, EDV, ESV, peak filling rate (PFR), peak ejection rate (PER) and phase standard difference (SD). The data were analyzed using χ 2 test, two-sample t test, paired t test and linear correlation analysis by SPSS 17.0. Results: The radiochemical purities of 99 Tc m -TF and 99 Tc m -MIBI were (97.5±0.4) % and (99.1±0.2) % respectively. The coincidence rates of 99 Tc m -TF and 99 Tc m -MIBI G-MPI with CAG were 88.9% (40/45) and 90.5% (57/63), respectively. There was no significant difference between G-MPI results of the two agents (χ 2 =0.389, P>0.05). There was also no significant difference between left ventricular functional parameters of the two agents (LVEF:(62.60±13.56)% vs (60.52±7.08)%, t=0.940; EDV: (103.3±17.29) ml vs (98.52±19.37) ml, t=1.348; ESV: (41.73±12.69) ml vs (46.05±10.81) ml, t=0.851; PER: (2.73±0.67)EDV/s vs (2.61±1.04) EDV/s, t=0.725; PFR: (2.13±0.80) EDV/s vs (2.07±1.09) EDV/s, t=0.339; phase SD: (5.58±4.16)° vs (5.97±4.64)°, t=0.450; all P>0.05).

A novel hyperthermophilic archaeon of strain HS-3 T , belonging to the family Sulfolobaceae, was isolated from an acidic terrestrial hot spring in Hakone Ohwaku-dani, Japan. Based on 16S rRNA gene sequence analysis, the closest phylogenetic relatives of strain HS-3 T were, first, Sulfolobus solfataricus (96.4 %) and, second, Sulfolobus shibatae (96.2 %), indicating that the strain belongs to the genus Sulfolobus. However, the sequence similarity to the type species of the genus Sulfolobus (Sulfolobus acidocaldarius) was remarkably low (91.8 %). In order to determine whether strain HS-3 T belongs to the genus Sulfolobus, its morphological, biochemical and physiological characteristics were examined in parallel with those of S. solfataricus and S. shibatae. Although there were some differences in chemolithotrophic growth between strain HS-3 T , S. solfataricus and S. shibatae, their temperature, pH and facultatively anaerobic characteristics of growth, and their utilization of various sugars were almost identical. In contrast, the utilization of various sugars by S. acidocaldarius was quite different from that of HS-3 T , S. solfataricus and S. shibatae. Phylogenetic evidence based on the 16S and the 23S rRNA gene sequences also clearly distinguished the monophyletic clade composed of strain HS-3 T , S. solfataricus, and S. shibatae from S. acidocaldarius. Based on these results, we propose a new genus and species, Saccharolobus caldissimus gen. nov., sp. nov., for strain HS-3 T , as well as two reclassifications, Saccharolobus solfataricus comb. nov. and Saccharolobus shibatae comb. nov. The type strain of Saccharolobus caldissimus is HS-3 T (=JCM 32116 T and InaCC Ar80 T ). The type species of the genus is Saccharolobus solfataricus.

Career advising in family medicine: a theoretical framework for structuring the medical student/faculty advisor interview

Full Text Available Background: There are unique challenges to recruiting students into the specialty of family medicine within academic medical centers. Methods: At Virginia Commonwealth University, we developed an advising framework to help students address institutional and personal obstacles to choosing family medicine as a career. Results: The role of a faculty advisor is not to direct the student to a career choice but rather to foster a mentor relationship and help the student come to his or her own realizations regarding career choice. The faculty advisor/medical student interview is conceptualized as five discussion topics: self-knowledge, perception, organizational voice, cognitive dissonance, and anticipatory counseling. Conclusion: This framework is intended to assist faculty in their efforts to encourage students to consider a career in family medicine.

Report on the scientifical feasibility of advanced separation

International Nuclear Information System (INIS)

2001-01-01

The advanced separation process Purex has been retained for the recovery of neptunium, technetium and iodine from high level and long lived radioactive wastes. Complementary solvent extraction processes will be used for the recovery of americium, curium and cesium from the high activity effluents of the spent fuel reprocessing treatment. This document presents the researches carried out to demonstrate the scientifical feasibility of the advanced separation processes: the adaptation of the Purex process would allow the recovery of 99% of the neptunium, while the association of the Diamex and Sanex (low acidity variant) processes, or the Paladin concept (single cycle with selective de-extraction of actinides) make it possible the recovery of 99.8% of the actinides III (americium and curium) with a high lanthanides decontamination factor (greater than 150). The feasibility of the americium/curium separation is demonstrated with the Sesame process (extraction of americium IV after electrolytic oxidation). Iodine is today recovered at about 99% with the Purex process and the dissolved fraction of technetium is also recovered at 99% using an adaptation of the Purex process. The non-dissolved fraction is retained by intermetallic compounds in dissolution residues. Cesium is separable from other fission products with recovery levels greater than 99.9% thanks to the use of functionalized calixarenes. The scientifical feasibility of advanced separation is thus demonstrated. (J.S.)

Objective Evidence points to a founder of the multifunctional CCN family, NOV/CCN3, as a circulating molecule involved in cardiac development, vascular homeostasis and inflammation. No data are available on the relationship between plasma NOV/CCN3 levels and cardiovascular risk factors in humans. This study investigated the possible relationship between plasma NOV levels and cardiovascular risk factors in humans. Methods NOV levels were measured in the plasma from 594 adults with a hyperlipidemia history and/or with lipid-lowering therapy and/or a body mass index (BMI) >30 kg/m2. Correlations were measured between NOV plasma levels and various parameters, including BMI, fat mass, and plasma triglycerides, cholesterol, glucose, and C-reactive protein. NOV expression was also evaluated in adipose tissue from obese patients and rodents and in primary cultures of adipocytes and macrophages. Results After full multivariate adjustment, we detected a strong positive correlation between plasma NOV and BMI (r = 0.36 p<0.0001) and fat mass (r = 0.33 p<0.0005). According to quintiles, this relationship appeared to be linear. NOV levels were also positively correlated with C-reactive protein but not with total cholesterol, LDL-C or blood glucose. In patients with drastic weight loss induced by Roux-en-Y bariatric surgery, circulating NOV levels decreased by 28% (p<0.02) and 48% (p<0.0001) after 3 and 6 months, respectively, following surgery. In adipose tissue from obese patients, and in human primary cultures NOV protein was detected in adipocytes and macrophages. In mice fed a high fat diet NOV plasma levels and its expression in adipose tissue were also significantly increased compared to controls fed a standard diet. Conclusion Our results strongly suggest that in obese humans and mice plasma NOV levels positively correlated with NOV expression in adipose tissue, and support a possible contribution of NOV to obesity-related inflammation.

When comparing the fate of Bohuslav Martinů to that of his pupil Jan Novák, interesting parallels can be found, not only in their work (with which this article does not deal), but also in their lives. Both composers met in 1947 in the U.S.A., and, for half a year, they worked together in New York. Novák’s 1950s compositions were strongly influenced by Martinů’s style. At the same time, both of them suffered the disgrace of the Czechoslovak cultural politics and its executors. Novák venerated ...

In recent years the electric industry has developed an increased interest in improving efficiency of nuclear power plants. EPRI has embarked upon a research project RP2407, Nuclear Plant Performance Improvements which is designed to address needs in this area. One product of this project has been the Thermal Performance Diagnostic Manual for Nuclear Power Plants (NP-4990P). The purpose of this manual is to provide engineering personnel at nuclear power plants with a consistent way in which to identify thermal performance problems. General Physics is also involved in the development of another computer system called Fossil Thermal Performance Advisor (FTPA) which helps operators improve performance for fossil power plants. FTPA is a joint venture between General Physics and New York State Electric and Gas Company. This paper describes both of these computer systems and uses the FTPA as an interesting comparison that illustrates the considerations required for the development of a computer system that effectively addresses the needs of the users

2016-01-01

An aerobic, Gram-stain-negative, oxidase- and catalase-positive, non-motile, non-spore-forming, rod-shaped, pink-pigmented bacterium, designated strain R49T, was isolated from soil. Flexirubin-type pigments were absent. Phylogenetic analysis based on its 16S rRNA gene sequence revealed that strain R49T formed a lineage within the family Cytophagaceae of the phylum Bacteroidetes that was distinct from the most closely related genera Dyadobacter (91.98-93.85 % sequence similarity), Persicitalea (88.69 %) and Runella (84.79-85.81 %). The major isoprenoid quinone was menaquinone-7 (MK-7) and the major polar lipid was phosphatidylethanolamine. The major cellular fatty acids were summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c), iso-C15 : 0, C16 : 1ω5c, C16 : 0 and iso-C17 : 0 3-OH. The DNA G+C content of strain R49T was 53.9 mol%. On the basis of phenotypic, genotypic and phylogenetic analysis, strain R49T represents a novel species of a new genus in the family Cytophagaceae, for which the name Rhabdobacter roseus gen. nov., sp. nov. is proposed. The type strain of Rhabdobacter roseus is R49T ( = KEMB 9005-318T = KACC 18395T = JCM 30685T).

The NOvA experiment measures long baseline νμ -->νe oscillations in Fermilab's NuMI beam. We employ two detectors equipped with over 10 thousand sets of data-taking electronics; avalanche photo diodes and front end boards which collect and process the scintillation signal from particle interactions within the detectors. These sets of electronics -as well as the systems which power and cool them- must be monitored and maintained at precise working conditions to ensure maximal data-taking uptime, good data quality and a lasting life for our detectors. This poster describes the automated systems used on NOvA to simultaneously monitor our data quality, diagnose hardware issues, track our performance and coordinate maintenance for the detectors.

Sachdev, Kanika [Fermilab

2016-11-29

NOvA is a long-baseline neutrino oscillation experiment on the NuMI muon neutrino beam at Fermilab. It consists of two functionally identical, nearly fully-active liquid-scintillator tracking calorimeters. The Near Detector (ND) at Fermilab is used to study the neutrino beam spectrum and composition before oscillations occur. The Far Detector in northern Minnesota, 810 km away, observes the oscillated beam and is used to extract the oscillation parameters. NOvA is designed to observe oscillations in two channels: disappearance channel ( ν μ → ν μ ) and ν e appearance channel ( ν μ → ν e ). This paper reports the measurements of both these channels based on the first NOvA data taken from February 16, 2014 till May 15, 2015

Inadequate communication between medical teams and families can lead to errors and poor-quality care. The objective was to understand why communication between the clinical team and families was not occurring consistently in the pediatric intensive care unit and improve the system using a multidisciplinary improvement team including a family advisor. This improvement project used Lean Six Sigma. The team observed updates and collected documented communication, survey, interview, and focus group data from families and staff. Root causes of failures included lack of assigned responsibility, lack of defined daily update, and lack of a daily communication standard. Process changes were implemented, resulting in an increased mean documented communication rate from 13% pre intervention to 65% post intervention that was sustained for more than 2 years (P < .001). Including a family advisor as an equal member of an improvement team provides family empowerment and a greater chance of success in complex areas. © The Author(s) 2015.

Doctoral Advisor-Advisee Pairing in STEM Fields: Selection Criteria and Impact of Faculty, Student and Departmental Factors

Directory of Open Access Journals (Sweden)

Simy Joy

2015-09-01

Full Text Available Unlike the doctoral programs in places where students are paired with advisors at the time of admission itself, most US programs require the students to choose their advisors, and the advisors to formally accept the students as advisees. Little research has been done to understand how students and faculty approach this mutual selection and pairing process. This paper examines this process in STEM departments (Science, Technology, Engineering and Mathematics, with specific focus on factors influencing the decisions. Based on focus groups and interviews of doctoral students and faculty from STEM departments in an American university, we identify criteria applied by students and faculty in making their choices. Students were found to assess faculty on available funding, area of research, personality, ability to graduate students fast, and career prospects for students, and faculty to assess students on their qualifications/credentials and perceived ability to contribute to research. We also found that this mutual assessment was not objective, but influenced by perceptions associated with faculty gender and career stage, and student nationality. In the end, whether students and faculty were actually paired with persons of their choice depended on departmental factors including prevalent pairing practices, restrictions on student numbers per faculty, and reward structure. We discuss implications of the findings for research and practice.

A novel genus and species, Methylocapsa acidiphila gen. nov., sp. nov., are proposed for a methane-oxidizing bacterium isolated from an acidic Sphagnum peat bog. This bacterium, designated strain B2T, represents aerobic, gram-negative, colourless, non-motile, curved coccoids that form conglomerates covered by an extracellular polysaccharide matrix. The cells use methane and methanol as sole sources of carbon and energy and utilize the serine pathway for carbon assimilation. Strain B2T is a moderately acidophilic organism with growth between pH 4.2 and 7.2 and at temperatures from 10 to 30 degrees C. The cells possess a well-developed system of intracytoplasmic membranes (ICM) packed in parallel on only one side of the cell membrane. This type of ICM structure represents a novel arrangement, which was termed type III. The resting cells are Azotobacter-type cysts. Strain B2T is capable of atmospheric nitrogen fixation; it possesses particulate methane monooxygenase and does not express soluble methane monooxygenase. The major phospholipid fatty acid is 18:1omega7c and the major phospholipids are phosphatidylglycerols. The G+C content of the DNA is 63.1 mol%. This bacterium belongs to the alpha-subclass of the Proteobacteria and is most closely related to the acidophilic methanotroph Methylocella palustris KT (97.3% 16S rDNA sequence similarity). However, the DNA-DNA hybridization value between strain B2T and Methylocella palustris K(T) is only 7%. Thus, strain B2T is proposed to comprise a novel genus and species, Methylocapsa acidiphila gen. nov., sp. nov. Strain B2T (= DSM 13967T = NCIMB 13765T) is the type strain.

Although nature of science (NOS) and nature of scientific inquiry (NOSI) are related to each other, they are differentiated as NOS is being more related to the product of scientific inquiry (SI) which is scientific knowledge whereas NOSI is more related to the process of SI (Schwartz et al. 2008). Lederman et al. (Journal of Research in Science Teaching, 51, 65-8, 2014) determined eight NOSI aspects for K-16 context. In this study, a science camp was conducted to teach scientific inquiry (SI) and NOSI to 24 6th and 7th graders (16 girls and 8 boys). The core of the program was guided inquiry in nature. The children working in small groups under guidance of science advisors conducted four guided-inquiries in the nature in morning sessions on nearby plants, animals, water, and soil. NOSI aspects were made explicit during and at the end of each inquiry session. Views about scientific inquiry (VASI) (Lederman et al. Journal of Research in Science Teaching, 51, 65-8, 2014) questionnaire was applied as pre- and post-test. The results of the study showed that children developed in all eight NOSI aspects, but higher developments were observed in "scientific investigations all begin with a question" and "there is no single scientific method," and "explanations are developed from data and what is already known" aspects. It was concluded that the science camp program was effective in teaching NOSI.

Leath, Audrey

President Clinton has nominated John H. “Jack” Gibbons to be Assistant to the President for Science and Technology, and director of the White House Office of Science and Technology Policy (OSTP). For over a decade, Gibbons has served as director of the Office of Technology Assessment (OTA), a bipartisan research arm of Congress.In nominating Gibbons, Clinton said, “I am delighted to appoint a brilliant scientist and gifted administrator… It is profoundly important that the president have a science advisor who understands science, who understands technology, who understands the practical application of these disciplines to the myriad of problems we face today. And I can tell you that from [Vice-president] Al Gore on down to every other member of Congress I have discussed John Gibbons with, I have hardly ever received more glowing and more consistent recommendations for anyone.”

Rapid repair advisor for motor-operated valves

International Nuclear Information System (INIS)

Somsel, J.K.

1991-01-01

This paper reports on the initial proposed application for the Rapid Repair Advisor project for motor-operated valves (MOVs). The expected benefits from an MOV testing expert system depend on the purpose of the testing. Straight acceptance testing (post-maintenance and surveillance) could benefit from field verification of test validity. Troubleshooting of failed operators is seldom difficult. Intermittent problems are difficult to resolve suggesting that trace recording capabilities are needed. Predictive diagnosis places the most demands on the interpretive skills of the engineer. However, the limit to predictive capabilities seems to lie in the design of the MOV and the measurable parameters. Utilities are expected to require a knowledgeable MOV maintenance engineer to make decisions on MOV maintenance and operability. The economics of developing an expert system are comparable to improved training for the end-users

A novel Gram-stain-negative, facultatively anaerobic, catalase- and oxidase-positive, non-motile and pink-pigmented bacterium, designated G22(T), was isolated from Gahai, a saltwater lake in Qinghai province, China. Optimal growth occurred at 33-35 °C, pH 7.0-7.5, and in the presence of 2-4% (w/v) NaCl. The DNA G+C content was 40.0 mol%. The major polar lipids were phosphatidylethanolamine and three unknown lipids. The predominant cellular fatty acids were iso-C15:0, anteiso-C15:0, iso-C17:0 3-OH and iso-C15:0 3-OH, and MK-7 was the main respiratory quinone. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain G22(T) fell within the class Bacteroidia. Its closest phylogenetic neighbour was the recently described species Draconibacterium orientale, the sole member of the family Draconibacteriaceae, with merely 90.04% sequence similarity. On the basis of phenotypic, chemotaxonomic and phylogenetic evidence observed, a novel species in a new genus, Tangfeifania diversioriginum gen. nov., sp. nov., is proposed within the family Draconibacteriaceae. The type strain is G22(T) ( = CICC 10587(T) =DSM 27063(T)).

Neutrino Oscillation Results from NOvA

CERN. Geneva

2016-01-01

NOvA is an accelerator long-baseline neutrino oscillation experiment optimised to measure electron neutrino appearance in a high-purity beam of muon neutrinos from Fermilab. The exciting discovery of the theta13 neutrino mixing angle in 2012 has opened a door to making multiple new measurements of neutrinos. These include leptonic CP violation, the neutrino mass ordering and the octant of theta23. NOvA with its 810km baseline and higher energy beam has about triple the matter effect of T2K which opens a new window on the neutrino mass ordering. With about 20% of our design beam exposure and significant analysis improvements we have recently released updated results. I will present both our disappearance and appearance measurements.

The tripeptide sequence asparagine-glycine-arginine (NGR) specifically recognizes aminopeptidase N (APN or CD13) receptors highly expressed on tumor cells and vasculature. Thus, NGR peptides can precisely deliver therapeutic and diagnostic compounds to CD13 expressing cancer sites. In this regard, 2 NGR peptide ligands, HYNIC-c(NGR) and HYNIC-PEG 2 -c(NGR), were synthesized, radiolabeled with 99m Tc, and evaluated in CD13-positive human fibrosarcoma HT-1080 tumor xenografts. The radiotracers, 99m Tc-HYNIC-c(NGR) and 99m Tc-HYNIC-PEG 2 -c(NGR), could be prepared in approximately 95% radiochemical purity and exhibited excellent in vitro and in vivo stability. The radiotracers were hydrophilic in nature with log P values being -2.33 ± 0.05 and -2.61 ± 0.08. The uptake of 2 radiotracers 99m Tc-HYNIC-c(NGR) and 99m Tc-HYNIC-PEG 2 -c(NGR) was similar in nude mice bearing human fibrosarcoma HT-1080 tumor xenografts, which was significantly reduced (P Tc-labeled HYNIC peptide could not be modulated through introduction of PEG 2 unit, thus posing a challenge for studies with other linkers towards enhanced tumor uptake and retention.

Determination of 99Mo contamination in 99mTc elute obtained from 99Mo/99mTc- generator

International Nuclear Information System (INIS)

Momennezhad, M.; Zakavi, S. R.; Sadeghi, R.

99m Tc is a widely used radioisotope in nuclear medicine centers which is obtained by elution from Mo-99/Tc-99m generators. Usually the generators are either supplied by the Iran Atomic Energy Agency or by private companies from foreign countries. In this study we have measured 99 Mo contamination in 99m Tc elute from different generators in a period of one year. Materials and Methods: The radionuclide impurity of the 99m Tc elute were studied in two types of radionuclide generators (A: produced in Iran and B: Imported from other country). In-vitro measurements were performed using dose calibrator. Direct measurements were made, using a standard canister at the time of milking of the generators and also in Subsequent hours after milking. Results: The results showed a mean of 99 Mo impurity in generators A and B to be 0.00932±0.0043 and 0.0170±0.0127 respectively. Although the results showed that the 99 Mo contamination in 99 mTc elute was lesser than the maximum accepted activity limit of 0.015%, the difference in these two types may reflect different methods of productions of generator, as well as the quality control procedures. Conclusion: The mean of 99 Mo contamination in generators produced in Iran Atomic Energy Organization was lesser than generators imported from foreign origin.

Urnaloricus gadi nov. gen. et nov. sp. (Loricifera, Urnaloricidae nov. fam.), an aberrant Loricifera with a viviparous pedogenetic life cycle.

Science.gov (United States)

Heiner, Iben; Kristensen, Reinhardt Møbjerg

2009-02-01

A new species of Loricifera, Urnaloricus gadi nov. gen. et nov. sp., is described from the Faroe Bank, located Southwest of the Faroe Islands, North Atlantic. The new species does not fit into any known families of Loricifera and therefore it is grouped into a new family Urnaloricidae nov. fam. The new species is characterized by having a very complicated life cycle that involves a large cyst-like mega-larva, two reduced larval instars and the Higgins-larvae eating their maternal stage from within. An adult stage is missing. This form of reproduction is called viviparous pedogenesis and normally is found only in nematodes and insects. In the life cycle of Urnaloricidae nov. fam., there are two types of free-living larval stages: a Higgins-larva and a mega-larva. The latter is found in two different forms, a pre- and a cyst-forming mega-larva. Additionally, there are two reduced life history stages, the reduced larval stage (probably a postlarva) and the ghost-larval stage inside the cyst-forming mega-larva. The external morphology of the two forms of mega-larvae is much reduced, e.g., the introvert has only a few rows of scalids when compared with the Higgins-larva. The pre mega-larva is free-living and can sometimes be covered with coccoliths. Internally, a large ovary with a few oocytes, a digestive system, and an internal armature with retracted scalids are present. The pre mega-larva presumably molts into a cyst-forming mega-larva and thereby the ovary is now seen inside the cyst-forming mega-larva. The cyst-forming mega-larva has the same structures as in the pre mega-larva though here the scalids are protruded and there is a gonopore. Inside the cyst-forming mega-larva the ovary produces more oocytes and begins to fill out the entire lumen. At this stage the cyst-forming mega-larva molts first to the presumed postlarval stage, and then this stage molts to a ghost-larva. Hence, the ovary now matures inside the ghost-larva, which is surrounded by both the

Lu, Yi; Wood, R.M.

1993-01-01

The Welding Manual Advisor (WMA) is an object oriented expert system designed to assist Northern States Power (NSP) personnel in implementing the company's Welding Manual. The expert system captures the knowledge of welding experts, addresses important issues in welding activities and automates the use of the Welding Manual. It is estimated that use of the WMA will save $81,000 over the next six years at NSP, because of the reduction of labor and errors in the use of the Welding Manual, and facilitation of training of NSP personnel. The important features of the WMA include the accuracy and consistency in determining welding procedure and requirements, update capability, user friendly interface, on-line help function, back-up capability, and well-documented manuals

Reclassification of Halothiobacillus hydrothermalis and Halothiobacillus halophilus to Guyparkeria gen. nov. in the Thioalkalibacteraceae fam. nov., with emended descriptions of the genus Halothiobacillus and family Halothiobacillaceae.

Science.gov (United States)

Boden, Rich

The genus Halothiobacillus contains four species of obligate autotrophs with validly published names, of which Halothiobacillus halophilus and Halothiobacillus hydrothermalis are very distant from the type species - on the basis of the 16S rRNA gene, they have 90.7 % and 90.9 % identity to that of the type species, Halothiobacillus neapolitanus. As these values fall below the Yarza cut-off for the rank of genus, and these two species also show no clear affiliation to the closely related genus Thioalkalibacter, a polyphasic study was undertaken to determine if they represent a separate genus. Unlike Halothiobacillus spp. sensu stricto, H. halophilus and H. hydrothermalis are halophilic (rather than halotolerant) and moderately alkaliphilic (rather than neutrophilic) and additionally do not produce tetrathionate as a detectable intermediate of thiosulfate metabolism, indicating some significant metabolic differences. On the basis of these data and of functional gene examination, it is proposed that they be circumscribed as a new genus Guyparkeria gen.nov, for which the type species is Guyparkeria halophila gen. nov., comb. nov. Additionally, Thioalkalibacter and Guyparkeria gen. nov. fall distant from the Halothiobacillaceae so the Thioalkalibacteraceae fam. nov. is proposed, for which Thioalkalibacter is the type genus. Emended descriptions of Halothiobacillus, Halothiobacillus neapolitanus and the Halothiobacillaceae are provided.

A novel actinomycete, designated strain NEAU-gq9(T), was isolated from corn root (Zea mays L.) and characterized using a polyphasic approach. The organism was found to have morphological and chemotaxonomic characteristics typical of the genus Micromonospora. On the basis of 16S rRNA gene sequence similarity studies, strain NEAU-gq9(T) was most closely related to Micromonospora zamorensis CR38(T) (99.3%), Micromonospora jinlongensis NEAU-GRX11(T) (99.2%), Micromonospora saelicesensis Lupac 09(T) (99.2%), Micromonospora chokoriensis 2-19(6)(T) (98.9%), Micromonospora coxensis 2-30-b(28)(T) (98.6%) and Micromonospora lupini Lupac 14N(T) (98.5%). Phylogenetic analysis based on the 16S rRNA gene and gyrB gene demonstrated that strain NEAU-gq9(T) is a member of the genus Micromonospora and supported the closest phylogenetic relationship to M. zamorensis CR38(T), M. jinlongensis NEAU-GRX11(T), M. saelicesensis Lupac 09(T), M. chokoriensis 2-19(6)(T) and M. lupini Lupac 14N(T). A combination of DNA-DNA hybridization, morphological and physiological characteristics indicated that the novel strain could be readily distinguished from the closest phylogenetic relatives. Therefore, it is proposed that strain NEAU-gq9(T) represents a novel species of the genus Micromonospora, for which the name Micromonospora zeae sp. nov. is proposed. The type strain is NEAU-gq9(T) (=CGMCC 4.7092(T)=DSM 45882(T)).

About the 'scientification' of politics by way of scientific expertise by advisory bodies. Social science expertise and desicion-making in social problem areas in the Federal Republic of Germany

International Nuclear Information System (INIS)

Wagner, P.

1985-01-01

Taking the examples of the Council of Economic Advisors, the Education Council and the Federal Parliament's Commission of Inquiry on Future Nuclear Energy Policy, this paper analyses political situations in the Federal Republic of Germany in which social science expertise entered public debate and decision-making in certain social problem areas in a very pronounced way. By considering the social context in which these advisory bodies were created, an attempt is made to link an analysis of different social actors' interests to a review of existing knowledge and patterns of interpretation in the social sciences. It is shown that by using social science findings some actors achieved advantages in justifying and legitimating their political positions and that subsequently the relations of actors in some arenas of conflict changed-without, however, allowing to relate this causally only to the use of scientific knowledge. If, however, the use of scientific arguments is rapidly generalized, the confrontation of expertise and counter-expertise by opposing actors becomes usual practice. This, in turn, provides for questions concerning their 'scientificity', which the social sciences are asked to take up in reflections of their relation to social practice. (orig./HSCH) [de

A bacterial strain named BSTT44(T) was isolated in the course of a study of endophytic bacteria occurring in stems and roots of potato growing in a soil from Salamanca, Spain. The 16S rRNA gene sequence had 99.7% identity with respect to that of its closest relative, Pseudomonas psychrophila E-3T, and the next most closely related type strains were those of Pseudomonas fragi, with 99.6% similarity, Pseudomonas deceptionensis, with 99.2% similarity, and Pseudomonas lundensis, with 99.0% similarity; these results indicate that BSTT44(T) should be classified within the genus Pseudomonas. Analysis of the housekeeping genes rpoB, rpoD and gyrB confirmed its phylogenetic affiliation and showed identities lower than 92% in all cases with respect to the above-mentioned closest relatives. Cells of the strain bore one polar-subpolar flagellum. The respiratory quinone was Q-9.The major fatty acids were C16:0, C18:1ω7c and summed feature 3 (C16:1ω7c and/or C16:1ω6c). The strain was oxidase-, catalase- and urease-positive and the arginine dihydrolase system was present, but tests for nitrate reduction, β-galactosidase production and aesculin hydrolysis were negative. It could grow at 35 °C and at pH 5-9.The DNA G+C content was 60.2 mol%. DNA-DNA hybridization results showed less than 48% relatedness with respect to the type strains of the four most closely related species. Therefore, the combined results of genotypic, phenotypic and chemotaxonomic analyses support the classification of strain BSTT44 into a novel species of the genus Pseudomonas, for which the name Pseudomonas endophytica sp. nov. is proposed. The type strain is BSTT44(T) ( = LMG 28456(T) = CECT 8691(T)).

Strain Gsoil 098(T), a Gram-positive, non-spore-forming, non-motile coccus, was isolated from soil from a ginseng field in South Korea and characterized in order to determine its taxonomic position. 16S rRNA gene sequence analysis revealed that strain Gsoil 098(T) belongs to the family Nocardioidaceae, and the highest degrees of sequence similarity were found with Aeromicrobium marinum T2(T) (99.0%), A. panaciterrae Gsoil 161(T) (98.9%), A. alkaliterrae KSL-107(T) (98.4%), A. fastidiosum KCTC 9576(T) (98.1%) and A. erythreum NRRL B-3381(T) (97.5%). Chemotaxonomic analysis revealed that strain Gsoil 098(T) possesses menaquinone MK-9(H(4)) and predominant fatty acids C(16 : 0), 10-methyl C(18:0) and C(18:0). DNA-DNA hybridization results and physiological and biochemical tests clearly demonstrated that strain Gsoil 098(T) represents a distinct species. Based on these data, Gsoil 098(T) (=KCTC 19207(T) =JCM 14732(T) =GBS 39(T)) should be classified as the type strain of a novel Aeromicrobium species, for which the name Aeromicrobium ginsengisoli sp. nov. is proposed.

Spent 99Mo/99mTc generator as an economical source of 99Mo

International Nuclear Information System (INIS)

El-Kolaly, M.T.

1990-01-01

An improved method for utilization and purification of 99 Mo from spent 90 Mo/ 99m Tc generators has been described. After washing the generator with saline to remove the generated 99m Tc, followed by 2 mL 5 M NaOH containing a few drops of H 2 O 2 , the 99 Mo was quantitatively eluted from the generator with 5 mL 5 M NaOH. The alkaline eluate containing 99 Mo was contaminated with partially dissolved alumina. In the present method, an anion-exchange resin Dowex 1 x 8 column was used for purification of 99 Mo from the contaminating alumina. The resultant 99 Mo was of high purity and contained 3+ /mL 99 Mo solution, as estimated by atomic absorption. (author)

2012-01-01

The NOvA experiment is a long baseline neutrino experiment design to make precision probes of the structure of neutrino mixing. The experiment features a unique deadtimeless data acquisition system that is capable acquiring and building an event data stream from the continuous readout of the more than 360,000 far detector channels. In order to achieve its physics goals the experiment must be able to buffer, correlate and extract the data in this stream with the beam-spills that occur that Fermilab. In addition the NOvA experiment seeks to enhance its data collection efficiencies for rare class of event topologies that are valuable for calibration through the use of data driven triggering. The NOvA-DDT is a prototype Data-Driven Triggering system. NOvA-DDT has been developed using the Fermilab artdaq generic DAQ/Event-building toolkit. This toolkit provides the advantages of sharing online software infrastructure with other Intensity Frontier experiments, and of being able to use any offline analysis module-unchanged-as a component of the online triggering decisions. We have measured the performance and overhead of NOvA-DDT framework using a Hough transform based trigger decision module developed for the NOvA detector to identify cosmic rays. The results of these tests which were run on the NOvA prototype near detector, yielded a mean processing time of 98 ms per event, while consuming only 1/16th of the available processing capacity. These results provide a proof of concept that a NOvA-DDT based processing system is a viable strategy for data acquisition and triggering for the NOvA far detector.

2016-03-01

Despite an increase in inclusive studies in recent years, research on the views of the people with and without disabilities who have participated in these studies is scarce. The aim of this study was to explore the perceptions and views of advisors with intellectual disabilities and non-disabled researchers who collaborated together on a joint project to study transition to adulthood. Two questionnaires were devised, one for advisors and one for researchers; two focus groups were held with people with intellectual disabilities, three focus groups with researchers, and one focus group with all participants together. Thematic analysis was used for the data analysis. The advisors valued this experience as an opportunity to learn new skills, freely express themselves on matters that affect them, and engage in a socially valued activity. The researchers considered that the participation of people with intellectual disabilities contributed to improving the quality of the research. The study provides a better understanding of inclusive research processes by taking into account participants' views. © 2015 John Wiley & Sons Ltd.

Two novel actinomycete isolates, designated strains NEAU-A4 T and NEAU-A3, were isolated from rhizosphere soil of wheat (Triticumaestivum L.) and characterized using a polyphasic approach. Morphological and chemotaxonomic characteristics of the two strains coincided with those of the genus Streptomyces. The 16S rRNA gene sequence analysis showed that the two isolates exhibited 99.6 % 16S rRNA gene sequence similarity with each other and that they were most closely related to Streptomyces violaceorectus DSM 40279 T (98.8, 99.0 %). Phylogenetic analysis based on 16S rRNA gene sequences indicated that the two strains clustered together and formed a separate subclade. Furthermore, a combination of DNA-DNA hybridization results and some physiological and biochemical properties demonstrated that the two strains could be distinguished from its closest relative. Therefore, it is proposed that strains NEAU-A4 T and NEAU-A3 should be classified as representatives of a novel species of the genus Streptomyces, for which the name Streptomycestritici sp. nov. is proposed. The type strain is NEAU-A4 T (=CGMCC 4.7393 T =DSM 104540 T ).

Few empirical data exist on how decision making about health differs from that in other crucial life domains with less threatening consequences. To shed light on this issue we conducted a study with 175 young adults (average age 19 years). We presented the participants with scenarios involving advisors who provided assistance in making decisions about health, money, and career. For each scenario, participants were asked to what extent they wanted the advisor to exhibit several leadership styles and competencies and what role (active, collaborative, or passive) they preferred to play when making decisions. Results show that decision making about health is distinct from that in the other domains in three ways. First, most of the participants preferred to delegate decision making about their health to their physician, whereas they were willing to collaborate or play an active role in decision making about their career or money. Second, the competencies and leadership style preferred for the physician differed substantially from those desired for advisors in the other two domains: Participants expected physicians to show more transformational leadership--the style that is most effective in a wide range of environments--than those who provide advice about financial investments or career. Finally, participants' willingness to share medical decision making with their physician was tied to how strongly they preferred that the physician shows an effective leadership style. In contrast, motivation to participate in decision making in the other domains was not related to preferences regarding advisors' leadership style or competencies. Our results have implications for medical practice as they suggest that physicians are expected to have superior leadership skills compared to those who provide assistance in other important areas of life.

An aerobic, budding, dark pink to red-pigmented bacterium was isolated from an acidic boreal Sphagnum peat bog and designated strain SP5T. Cells of this strain were non-motile spheres that were uniformly covered with crateriform pits and fimbria, and tended to form aggregates during growth in liquid media. Strain SP5T was capable of growth between pH 4.0 and pH 6.8 (optimum at pH 5.5-6.0) and at temperatures between 10 and 30 °C (optimum at 20-25 °C). The preferred growth substrates were sugars and some heteropolysaccharides. The major fatty acids were C20 : 1ω9c, C16 : 1ω9c and C16 : 0, and the major polar lipid was trimethylornithine. Cells contained also significant amounts of bound (ω-1)OH-C30 : 1 fatty acid. The quinone was menaquinone-6, and the G+C content of the DNA was 60.7 mol%. Strain SP5T was a member of the order Planctomycetales and belonged to the phylogenetic lineage defined by the genus Gemmata. It displayed 88 and 89 % 16S rRNA gene sequence similarity to Gemmata obscuriglobusUQM 2246T and 'Gemmata massiliana' IIL30, 89 % to Zavarzinella formosa A10T and 86 % to Telmatocola sphagniphila SP2T. However, strain SP5T differed from members of these genera by cell morphology, substrate utilization pattern and fatty acid composition. Based on these data, the novel isolate should be considered as representing a novel species of a new genus of planctomycetes, for which the name Fimbriiglobus ruber gen. nov., sp. nov, is proposed. The type strain is SP5T (=LMG 29572T=VKM B-3045T). We also suggest the establishment of a novel family, Gemmataceaefam. nov., which includes the phylogenetically related genera Gemmata, Zavarzinella, Telmatocola and Fimbriiglobus.

To make its core measurements, the NOvA experiment needs to make real-time data-driven decisions involving beam-spill time correlation and other triggering issues. NOvA-DDT is a prototype Data-Driven Triggering system, built using the Fermilab artdaq generic DAQ/Event-building tools set. This provides the advantages of sharing online software infrastructure with other Intensity Frontier experiments, and of being able to use any offline analysis module--unchanged--as a component of the online triggering decisions. The NOvA-artdaq architecture chosen has significant advantages, including graceful degradation if the triggering decision software fails or cannot be done quickly enough for some fraction of the time-slice ``events.'' We have tested and measured the performance and overhead of NOvA-DDT using an actual Hough transform based trigger decision module taken from the NOvA offline software. The results of these tests--98 ms mean time per event on only 1/16 of th e available processing power of a node, and overheads of about 2 ms per event--provide a proof of concept: NOvA-DDT is a viable strategy for data acquisition, event building, and trigger processing at the NOvA far detector.

Full Text Available The position of regional medical advisor (RMA is relatively new in the pharmaceutical industry and its roles and responsibility are still evolving. The RMA is a field based position whose main mission is to foster collaborative relationships with the key opinion leaders (KOLs and to facilitate the exchange of unbiased scientific information between the medical community and the company. Field-based medical liaison teams are expanding world-wide as part of the pharmaceutical industry′s increased focus on global operations including emerging markets. Now, the position of the RMA has evolved into comprehensive, complex, highly interactive, targeted, highly strategic, innovative, and independent role since its inception by the Upjohn Company in 1967. The major objective of the RMA is to develop the professional relationships with the health-care community, particularly KOLs, through peer-to-peer contact. The RMA can facilitate investigator-initiated clinical research proposals from approval until completion, presentation, and publication. It is possible for a RMA to have valuable access to KOLs through his expertise in the clinical research. The RMA can assist in the development, review, and follow-up of the clinical studies initiated within the relevant therapeutic area at the regional/local level. The RMA can lead regional/local clinical projects to ensure that all clinical trials are conducted in compliance with the International Conference of Harmonisation Good Clinical Practice (ICH GCP guidelines.

Osteomyelitis, which is characterized by progressive inflammatory destruction and new opposition of bone, is still a difficult infection to treat. The clinical diagnosis in late stages is achieved easily, but an early diagnosis is more challenging. Staphylococcus aureus is a common agent found in osteomyelitis and bone prostheses infection. Diagnosis by scintigraphy has advantages because it is a non-invasive procedure and is able to perform an early diagnosis even before anatomic changes. Thus, nuclear medicine could contribute to an accurate diagnosis since specific radiopharmaceuticals were developed. In this study, aptamers selected to Staphylococcus aureus were labeled with 99m Tc and used for bacteria identification in an osteomyelitis experimental model. The aptamers selected to S. aureus were directly labelled with 99m Tc and were evaluated by biodistribution studies. Wistar rats with intraosseous infection in the right paw were used. A random aptamer labelled with 99m Tc was as control. Six animals were used in each group. The aptamers labeled with 99m Tc were able to identify the infection foci caused by S. aureus displaying a target/non-target ratio of 2,23 ± 0,20, after 3 h. The control group presented a target/non-target ratio 1,08 ± 0.23. The results indicated that the radiolabeled aptamers were able to identify specifically the infection foci and they should be further explored for infection diagnosis by scintigraphy. (author)

The taxonomic positions of Enterobacter oryziphilus and Enterobacter oryzendophyticus were re-examined on the basis of concatenated partial rpoB, atpD, gyrB and infB gene sequence analysis. The reconstructed phylogenetic tree based upon concatenated partial rpoB, atpD, gyrB and infB gene sequences clearly showed that E. oryziphilus and E. oryzendophyticus and all defined species of the genus Kosakonia form a clade separate from other genera of the family Enterobacteriaceae, and, therefore, these species of the genus Enterobacter should be transferred to the genus Kosakonia. E. oryziphilus and E. oryzendophyticus are reclassified as K. oryziphila comb. nov. (type strain REICA_142T=LMG 26429T=NCCB 100393T) and K. oryzendophytica comb. nov. (type strain REICA_082T=LMG 26432T=NCCB 100390T), respectively.

Shah, S.Q.; Khan, M.R.; Khan, A.U.

2011-01-01

The radiosynthesis of 99m Tc-Novobiocin ( 99m Tc-NBN) complex and its suitability as a radiotracer for infection imaging was assessed. The radiochemical purity (RCP) of the 99m Tc-NBN complex was determined using radio-TLC and radioactive HPLC and biodistribution was studied in artificially infected (A.I.) rats and rabbit, using single well gamma counter (SWGRC) interface with scalar count rate meter (SCRM) and Gamma Camera (γ-CM). The maximum RCP observed for the preparation having 2 mg of NBN, 111 MBq of sodium pertechnetate (Na 99m TcO 4 ) and 125 μL of SnF 2 (1 μg/μL in 0.01 N HCl) at a pH 5.6 was 98.97±0.40% and remained stable >90% up to 120 min. The activity of the 99m Tc-NBN in the infected muscle (TI) was significantly increased from 6.50±0.15 to 19.00±0.17% and decreased in the inflamed muscle (TII), normal muscle (NT), blood, liver, spleen, stomach and intestine within 120 min. The TI/NT and TII/NT ratios were 7.60±1.08 and 1.60±1.14. The Whole Body Static (WBS) images of A.I. rabbit were obtained at 30, 40, 50 and 60 min after the I.V. administration of 111 MBq of 99m Tc-NBN to the A.I. rabbit. The stability in saline and serum, higher TI/NT, lower TII/NT ratios and WBS images confirmed the feasibility of the 99m Tc-NBN complex as an infection imaging agent. (orig.)

Theoretical construction of the contextualized dynamics of the constant shaping of advisor professors in the teaching unit

Directory of Open Access Journals (Sweden)

Nirma Pérez-Pelipiche

2016-10-01

Full Text Available This work paper shows research results on the contextualized dynamics of the constant shaping of advisor professors in the teaching unit, taking epistemological foundations as a starting point, which substantiate their theoretical construction. A model has been displayed basing on comprehension and interpretation of this process as a whole, in which its subsystems, components, structure, relations and levels among them, prove contradictions that become evident in such process, therefore allowing to structure the dynamics of shaping professors as an instrument, earning, as a result, the transforming capability of advisor professors when practicing their skill, having the teaching unit as a scenary. In that way we used different techniques: questionnaire, interviews, observation, statistical techniques and methods: historical-logical; analysis-synthesis and systemic-structural-functional, all of those ones from the hermeneutic-dialectic focus.

Acaricomes phytoseiuli gen. nov., sp. nov., isolated from the predatory mite Phytoseiulus persimilis.

Pukall, Rüdiger; Schumann, Peter; Schütte, Conny; Gols, Rieta; Dicke, Marcel

2006-02-01

A Gram-positive, rod-shaped, non-spore-forming bacterium, strain CSCT, was isolated from diseased, surface-sterilized specimens of the predatory mite Phytoseiulus persimilis Athias-Henriot and subjected to polyphasic taxonomic analysis. Comparative analysis of the 16S rRNA gene sequence revealed that the strain was a new member of the family Micrococcaceae. Nearest phylogenetic neighbours were determined as Renibacterium salmoninarum (94.0%), Arthrobacter globiformis (94.8%) and Arthrobacter russicus (94.6%). Although the predominant fatty acids (anteiso C15:0), cell-wall sugars (galactose, glucose) and polar lipids (diphosphatidylglycerol, phosphatidylglycerol, phosphatidylinositol) are in accordance with those of members of the genus Arthrobacter, strain CSCT can be distinguished from members of the genus Arthrobacter by biochemical tests, the absence of a rod-coccus life cycle and the occurrence of the partially saturated menaquinone MK-10(H2) as the predominant menaquinone. The DNA G+C content is 57.7 mol%. On the basis of morphological, chemotaxonomic and phylogenetic differences from other species of the Micrococcaceae, a novel genus and species are proposed, Acaricomes phytoseiuli gen. nov., sp. nov. The type strain is CSCT (=DSM 14247T=CCUG 49701T).

An intelligent, knowledge-based multiple criteria decision making advisor for systems design

of an appropriate decision making method. Furthermore, some DMs may be exclusively using one or two specific methods which they are familiar with or trust and not realizing that they may be inappropriate to handle certain classes of the problems, thus yielding erroneous results. These issues reveal that in order to ensure a good decision a suitable decision method should be chosen before the decision making process proceeds. The first part of this dissertation proposes an MCDM process supported by an intelligent, knowledge-based advisor system referred to as Multi-Criteria Interactive Decision-Making Advisor and Synthesis process (MIDAS), which is able to facilitate the selection of the most appropriate decision making method and which provides insight to the user for fulfilling different preferences. The second part of this dissertation presents an autonomous decision making advisor which is capable of dealing with ever-evolving real time information and making autonomous decisions under uncertain conditions. The advisor encompasses a Markov Decision Process (MDP) formulation which takes uncertainty into account when determines the best action for each system state. (Abstract shortened by UMI.)

Head and neck cancer is one of the 10 most frequent cancers worldwide, with an estimated 500000 new cases diagnosed annually. Treatment of head and neck cancers require a multidisciplinary approach due their complexity and the functional and esthetic alterations that cancer can cause. The interest of the scientific community in a specific subject can be evaluated by analyzing of the number and the quality of published papers on the topic. The information obtained from PubMed (www.ncbi.nlm.nih.gov/sites/entrez) has been used as a tool in various publications to aid the evaluation of the scientific interest in specific research areas The aim of this work is to evaluate, using PubMed, the scientific interest in studies of head and neck cancer treatments such as radiotherapy, chemotherapy and surgery. The searches were performed on PubMed for publications from the period of 1949 to 2008 using the search terms 'head and neck cancer' and 'surgery' or 'radiotherapy' or 'chemotherapy'. The number of publications per year was determined in each search. The percentage of publications was also calculated for each subject in each year. An interest factor in a subject (IFS) was also determined. The number of publications was higher for surgery than chemotherapy or radiotherapy. The calculated 1964 IFS for surgery was 14.79, 12.74 for radiotherapy, and 19.58 for chemotherapy. The 1995 IFS for surgery was 1.99, 2.09 for radiotherapy, and 2.08 for chemotherapy. The relation obtained for 1995 was maintained in the subsequent years. There are more publications related to surgical treatment for head and neck cancer when compared with radiotherapy and chemotherapy. Moreover, in the recent years there has an increased interest in treatments utilizing chemotherapy, or this associated to radiotherapy. (author)

We have for the first time succeeded in separating 99m Tc from a MoO 3 sample irradiated with accelerator neutrons free from any radioactive impurities and in formulating 99m Tc-methylene diphosphonate ( 99 mTc-MDP). 99 Mo, the mother nuclide of 99m Tc, was produced by the 100 Mo(n,2n) 99 Mo reaction using about 14 MeV neutrons provided by the 3 H(d,n) 4 He reaction at the Fusion Neutronics Source of Japan Atomic Energy Agency. The 99m Tc was separated from 99 Mo by sublimation and its radionuclide purity was confirmed to be higher than 99.99% by γ-spectroscopy. The labeling efficiency of 99m Tc-MDP was shown to be higher than 99% by thin-layer chromatography. These values exceed the United States Pharmacopeia requirements for a fission product, 99 Mo. Consequently, a 99m Tc radiopharmaceutical preparation formed by using the mentioned 99 Mo can be a promising substitute for the fission product 99 Mo, which is currently produced using a highly enriched uranium target in aging research reactors. A longstanding problem to ensure a reliable and constant supply of 99 Mo in Japan can be partially mitigated. (author)

Career Preparation: An Often Omitted Element of the Advisor-Graduate Student Relationship

Science.gov (United States)

McManus, D. A.

2001-05-01

Most graduate research advisors care about the education of their graduate students. However, they often define "graduate education" so narrowly that it consists only of solving a research problem. This narrow definition is consistent with their principal goal as geoscientists, to understand the Earth better, and with the reward system typical of research universities, with its emphasis on research. As a result, most advisors usually well prepare students to be researchers in research universities. Research, however, is only part of a faculty member's duties. Commonly omitted is mentoring in the teaching and service duties of a faculty member. Students interested in teaching, in positions in other academic institutions, or in careers outside of academia may be perceived as questioning the advisors' career values and may not be encouraged in these interests. Graduate students should take an active role in their education. In addition to seeking information on career preparation from the campus career center and teaching center and from books, newsmagazines, newspapers, and seminars, students should also seek mentors who have demonstrated an interest in what the student is interested in: teaching and service, as well as research, or in careers outside academia. These mentors may be the students' committee members, other faculty members, or other professional geoscientists. With a broad base of information and some personal decisions, students will have a rationale for exploring careers. The questions students ask can now be more specific: How do they gain the requisite breadth in knowledge and the beneficial skills, beyond the depth of the research experience, and how do they gain opportunities to practice these skills? In short, how can they experience, and preferably practice, what professional geoscientists do in particular careers? If necessary, graduate students can work together to answer these questions by inviting experts to offer workshops in the department

A mesophilic, sulfate-reducing bacterium (strain SaxT) was isolated from marine coastal sediment in the Baltic Sea and originally described as a 'Desulfoarculus' sp. It used a large variety of substrates, ranging from simple organic compounds and fatty acids to aromatic compounds as electron donors. Autotrophic growth was possible with H2, CO2 and formate in the presence of sulfate. Sulfate, thiosulfate and sulfite were used as electron acceptors. Sulfur and nitrate were not reduced. Fermentative growth was obtained with pyruvate, but not with fumarate or malate. Substrate oxidation was usually complete leading to CO2, but at high substrate concentrations acetate accumulated. CO dehydrogenase activity was observed, indicating the operation of the CO dehydrogenase pathway (reverse Wood pathway) for CO2 fixation and complete oxidation of acetyl-CoA. The rod-shaped cells were 0.8-1.0 microm wide and 1.5-2.5 microm long. Spores were not produced and cells stained Gram-negative. The temperature limits for growth were between 10 and 42 degrees C (optimum growth at 28-32 degrees C). Growth was observed at salinities ranging from 5 to 110 g NaCl l(-1), with an optimum at 10-25 g NaCl l(-1). The G+C content of the DNA was 62.4 mol%. Vitamins were required for growth. Based on the 16S rRNA gene sequence, strain SaxT represents a new genus within the delta-subclass of the Proteobacteria. The name Desulfotignum balticum gen. nov., sp. nov. is proposed. After the 16S rDNA sequences of all members of the genus Desulfobacterium were published (GenBank accession nos. AJ237601-AJ237604, AJ237606, AJ237607), the need to reclassify most members of the genus Desulfobacterium became obvious due to their strong phylogenetic affiliation to other genera. Here, we propose to reclassify Desulfobacterium phenolicum as Desulfobacula phenolica comb. nov. Desulfotignum balticum, Desulfobacterium phenolicum and Desulfobacula toluolica contain cellular fatty acids which have so far only been

Three rapidly growing mycobacterial strains, QIA-37 T , QIA-40 and QIA-41, were isolated from the lymph nodes of three separate Korean native cattle, Hanwoo (Bos taurus coreanae). These strains were previously shown to be phylogenetically distinct but closely related to Mycobacterium chelonae ATCC 35752 T by taxonomic approaches targeting three genes (16S rRNA, hsp6 and rpoB) and were further characterized using a polyphasic approach in this study. The 16S rRNA gene sequences of all three strains showed 99.7 % sequence similarity with that of the M. chelonae type strain. A multilocus sequence typing analysis targeting 10 housekeeping genes, including hsp65 and rpoB, revealed a phylogenetic cluster of these strains with M. chelonae. DNA-DNA hybridization values of 78.2 % between QIA-37 T and M. chelonae indicated that it belongs to M. chelonae but is a novel subspecies distinct from M. chelonae. Phylogenetic analysis based on whole-genome sequences revealed a 95.44±0.06 % average nucleotide identity (ANI) value with M. chelonae, slightly higher than the 95.0 % ANI criterion for determining a novel species. In addition, distinct phenotypic characteristics such as positive growth at 37 °C, at which temperature M. chelonae does not grow, further support the taxonomic status of these strains as representatives of a novel subspecies of M. chelonae. Therefore, we propose an emended description of Mycobacterium chelonae, and descriptions of M. chelonae subsp. chelonae subsp. nov. and M. chelonae subsp. bovis subsp. nov. are presented; strains ATCC 35752 T (=CCUG 47445 T =CIP 104535 T =DSM 43804 T =JCM 6388 T =NCTC 946 T ) and QIA-37 T (=KCTC 39630 T =JCM 30986 T ) are the type strains of the two novel subspecies.

A Gram-negative, strictly aerobic, diplococcoid bacterium (strain D2-3T) was isolated from the biofilter of a recirculating marine aquaculture system. Phylogenetic analysis of the 16S rRNA gene sequence of D2-3T indicated that the new organism occupied a novel lineage within the α-1 subclass...... of the DNA was 60.3±0.1 mol%. Phylogenetic, morphological, physiological, and biochemical analyses demonstrated that D2-3T represented a new aerobic phototrophic genus, for which the name Geminicoccus roseus gen. nov., sp. nov. is proposed for the type species (D2-3T=DSM 18922T=ATCC BAA-1445T)....

Effect of milking efficiency on Tc-99 content of Tc-99m derived from Tc-99m generators

International Nuclear Information System (INIS)

Bonnyman, J.

1983-01-01

Tc-99m obtained by separation from its parent Mo-99 always contains Tc-99 produced by decay of Tc-99m and Mo-99. Factors effecting the Tc-99/Tc-99m ratios are discussed. An HPLC method has been developed to measure the 99 TcO 4- content of sodium pertechnetate from generators with a detection limit of 0.9 ng Tc-99 for a 500 μl/ aliquot of TcO 4- -99m. First eluates of 10 chromatograph-ic generators gave Tc-99/Tc-99m ratios ranging from 3.5-46 ng Tc/mCi Tc-99m measured at the time of milking. The measurements indicate that Tc-99/Tc-99m ratios high enough to cause adverse labelling effects could be found in 'instant pertechnetate' and in the first eluate from Tc-99m generators for the activities normally used in radiopharmaceutical production

Production technologies for molybdenum-99 and technetium-99m

International Nuclear Information System (INIS)

1999-02-01

Technetium-99m (6.02 h) is the most widely used radioisotope in nuclear medicine, accounting for more than 80% of all diagnostic nuclear medicine procedures. It is almost exclusively produced from the decay of its parent 99 Mo. The present sources of 99 Mo are research reactors by using the (n,γ) nuclear reaction with natural Mo ( 98 Mo, ∼24%), resulting in inexpensive but low-specific activity 99 Mo, or by neutron-induced fission of 235 U, which results in expensive but high specific activity 99 Mo. This publication covers several aspects related to the production of 99 Mo and 99m Tc. The contributed papers reflect the current status of the technology and discuss potential alternative methodologies for the production of 99 Mo and 99m Tc for medical use. The first four papers address the technologies using nuclear reactors, including the description of a new method using an aqueous homogenous reactor core for production of fission 99 Mo and the latest development efforts to fabricate 235 U low enriched targets (LEU, 235 U). The next five papers discuss the potential of utilizing particle accelerators and assess the current status of the available nuclear data for the production of both, 99 Mo and 99m Tc with proton and deuteron beams. The last paper discusses a new technology based on gel system for the preparation of 99 Mo/ 99m Tc generators using low specific activity 99 Mo produced in research reactors by the neutron activation of natural and inexpensive molybdenum oxide targets. Each individual paper was indexed and abstracted

Purpose: This study's aim was to characterize the nature of students' research conducted for a Master of Science in Physical Therapy (MScPT) degree programme at a Canadian university and evaluate the lead advisors' perspectives of its impact on their research capacity, education, clinical practice, knowledge translation, and health policy. Methods: We conducted a quantitative, cross-sectional, retrospective review of research reports from 2003 to 2014 to characterize the MScPT students' research and a quantitative, cross-sectional e-survey of lead research advisors to evaluate the impact of this research. Results: Data were abstracted from reports of 201 research projects completed between 2003 and 2014. Projects were conducted primarily in university-affiliated hospitals (41.6%) or the university's physical therapy department (41.1%), and the majority (52.5%) had a clinical focus. Of the 95 lead advisors of 201 projects, 59 advisors (response rate 62.1%) of 119 projects completed the survey questionnaire. The respondents most frequently identified clinical practice (45.1%) and advisors' research capacity (31.4%) as areas positively affected by the students' research. Conclusions: The MScPT students' research projects facilitate the conduct of extensive research internally and across affiliated hospitals. This research appears to advance not only clinical practice but also the ability of lead advisors to undertake research.

previously by DNA-DNA hybridization. These results clearly support the allocation of this species to a novel genus within the family Pasteurellaceae. The phenotypic separation of Histophilus somni gen. nov., sp. nov. from other members of the family can, for most strains, be based on capnophilia, yellowish...... pigmentation and indole production. However, due to phenotypic variation, the use of a species-specific PCR test based on the 16S rRNA gene is included in the species description. This is justified by the high sequence similarity of the 16S rRNA gene within the species and the fact that the highest sequence...

Bacterial strains MCy10943T and MCy10944T were isolated in 2014 from dried Nepalese soil samples collected in 2013 from Phukot, Kalikot, Western Nepal, and Godawari, Lalitpur, Central Nepal. The novel organisms showed typical myxobacterial growth characteristics, which include swarming colony and fruiting body formation on solid surfaces, and a predatory ability to lyse micro-organisms. The strains were aerobic, mesophilic, chemoheterotrophic and showed resistance to various antibiotics. The major cellular fatty acids common to both organisms were C17 : 0 2-OH, iso-C15 : 0, C16 : 1 and iso-C17 : 0. The G+C content of the genomic DNA was 72-75 mol%. Phylogenetic analysis showed that the strains belong to the family Cystobacteraceae, suborder Cystobacterineae, order Myxococcales. The 16S rRNA gene sequences of both strains showed 97-98 % similarity to Archangium gephyra DSM 2261T andCystobacter violaceus DSM 14727T, and 96.7-97 % to Cystobacter fuscus DSM 2262T and Angiococcus disciformis DSM 52716T. Polyphasic taxonomic characterization suggested that strains MCy10943T and MCy10944T represent two distinct species of a new genus, for which the names Vitiosangium cumulatum gen. nov., sp. nov. and Vitiosangium subalbum sp. nov. are proposed. The type strain of Vitiosangium cumulatum is MCy10943T (=DSM 102952T=NCCB 100600T) while that for Vitiosangium subalbum is MCy10944T (=DSM 102953T=NCCB 100601T). In addition, emended descriptions of the genera Archangium and Angiococcus, and of the family Cystobacteraceaeare provided.

New chromatographic systems for the quality control determination of 99Tcm-tetrofosmin

Full text: The manufacturer's method for assessing the radiochemical purity (RCP) of 99 Tc m -tetrofosmin requires the use of a volatile solvent system on silica gel impregnated thin layer chromatography strips, and is a time-consuming procedure (> 15 minutes). A rapid quality control procedure for this product has already been proposed which utilizes miniature Whatman 1 paper strips with ethyl acetate as the mobile phase, where 99 Tc m -tetrofosmin appears at the solvent front (R f 0.9). In our laboratory, this procedure was found to be unreliable, prompting us to develop two new and improved methods to successfully determine the % RCP of 99 Tc m -tetrofosmin. These include: (1) an Amprep anion exchange cartridge with absolute ethanol as the mobile phase; and (2) a miniature Whatman 17 strip with ethyl acetate:acetone [1:9] as the mobile phase. 99 Tc m -tetrofosmin elutes with the solvent, and 99 Tc m O 2 plus 99 Tc m O 4 -remain on the cartridge for the cartridge method. 99 Tc m -tetrofosmin moves with the solvent front (Rf 0.8) and the other 99 Tc m -impurities remain at the origin for the Whatman paper method. The % RCP of 99 Tc m -tetrofosmin (n = 8) by the manufacturer's method was 96.5 ± 1.5%, as compared to the cartridge method (98.0 ± 0.9%) and Whatman paper method (97.3 ± 0.9%) at 0-2 h post-reconstitution. The quality control determinations gave a result in 3 or 5 min for the cartridge or Whatman paper methods respectively. These methods can be used successfully in a dose calibrator for counting, particularly if the total counts are > 1.5 MBq. These new methods were found to be highly reproducible, convenient and rapid for the routine analysis of 99 Tc m -tetrofosmin preparations

Srinivas, T N R; Aditya, S; Bhumika, V; Kumar, P Anil

2014-02-01

Novel pinkish-orange pigmented, Gram-negative staining, half-moon shaped, non-motile, strictly aerobic strains designated AK24(T) and AK26 were isolated from water and sediment samples of Lonar Lake, Buldhana district, Maharahstra, India. Both strains were positive for oxidase, catalase and β-galactosidase activities. The predominant fatty acids were iso-C15:0 (41.5%), anteiso-C15:0 (9.7%), iso-C17:0 3OH (9.6%), iso-C17:1 ω9c (10.2%) and C16:1 ω7c/C16:1 ω6c/iso-C15:0 2OH (summed feature 3) (14.4%). The strains contained MK-7 as the major respiratory quinone, and phosphatidylethanolamine and five unidentified lipids as the polar lipids. Blast analysis of the 16S rRNA gene sequence of strain AK24(T) showed that it was closely related to Aquiflexum balticum, with a pair-wise sequence similarity of 91.6%, as well as to Fontibacter ferrireducens, Belliella baltica and Indibacter alkaliphilus (91.3, 91.2 and 91.2% pair-wise sequence similarity, respectively), but it only had between 88.6 and 91.0% pair-wise sequence similarity to the rest of the family members. The MALDI-TOF assay reported no significant similarities for AK24(T) and AK26, since they potentially represented a new species. A MALDI MSP dendrogram showed close similarity between the two strains, but they maintained a distance from their phylogenetic neighbors. The genome of AK24(T) showed the presence of heavy metal tolerance genes, including the genes providing resistance to arsenic, cadmium, cobalt and zinc. A cluster of heat shock resistance genes was also found in the genome. Two lantibiotic producing genes, LanR and LasB, were also found in the genome of AK24(T). Strains AK24(T) and AK26 were very closely related to each other with 99.5% pair-wise sequence similarity. Phylogenetic analysis indicated that the strains were members of the family Cyclobacteriaceae and they clustered with the genus Mariniradius, as well as with the genera Aquiflexum, Cecembia, Fontibacter, Indibacter, and Shivajiella

A recent study of a group of Burkholderia glathei-like bacteria resulted in the description of 13 novel species of the genus Burkholderia. However, our analysis of phylogenetic positions of these species and their molecular signatures (conserved protein sequence indels) showed that they belong to the genus Caballeronia, and we propose to transfer them to this genus. The reclassified species names are proposed as Caballeroniaarationis comb. nov., Caballeroniaarvi comb. nov., Caballeroniacalidae comb. nov., Caballeroniacatudaia comb. nov., Caballeroniaconcitans comb. nov., Caballeroniafortuita comb. nov., Caballeroniaglebae comb. nov., Caballeroniahypogeia comb. nov., Caballeroniapedi comb. nov., Caballeroniaperedens comb. nov., Caballeroniaptereochthonis comb. nov., Caballeroniatemeraria comb. nov. and Caballeronia turbans comb. nov. It is also proposed to reclassify Burkholderia jirisanensis as Paraburkholderiajirisanensis comb. nov. Based on the results of the polyphasic study, B. jirisanensis had been described as a member of the A-group of the genus Burkholderiaand the most closely related to Burkholderia rhizosphaerae, Burkholderia humisilvae and Burkholderia solisilvae currently classified as belonging to the genus Paraburkholderia.

Two actinomycete strains, designated YIM 56256(T) and YIM 61331(T), were isolated from the roots of Scoparia dulcis and Maytenus austroyunnanensis, two Chinese medicinal plants, and their taxonomic status was established based on a polyphasic investigation. The organisms were found to have chemical and morphological markers typical of members of the genus Glycomyces. 16S rRNA gene sequence analysis showed that they were closely related to each other and to Glycomyces sambucus E71(T). A battery of physiological characteristics and levels of DNA-DNA relatedness indicated that strains YIM 56256(T) and YIM 61331(T) represent two novel species, clearly different from the related known Glycomyces species. On the basis of the data presented, it is evident that each of these strains represents a novel species of the genus Glycomyces, for which the names Glycomyces scopariae sp. nov. (type strain YIM 56256(T) =KCTC 19158(T) =DSM 44968(T)) and Glycomyces mayteni sp. nov. (type strain YIM 61331(T) =KCTC 19527(T) =CCTCC AA 208004(T)) are proposed.

Shift technical advisors: in the eyes of the NRC

International Nuclear Information System (INIS)

Crocker, L.P.

1981-01-01

Since January 1, 1980, the NRC has required that Shift Technical Advisors be on-shift at all operating nuclear power plants. The objective of the requirement is to assure that technical expertise is immediately available to each operating shift to assess off-normal events and to provide advice to control room personnel. Further, this advice and assistance is to be provided by an individual not responsible for control manipulations or for directing the activities of reactor operators. The long-term requirement for on-shift technical expertise is firm. However, the exact manner in which this expertise must be furnished has not been determined. Licensees have proposed various alternatives to meet this requirement. These proposals still are being reviewed by the NRC staff

Two catalase- and oxidase-negative Streptococcus-like strains, LMG 27682(T) and LMG 27684(T), were isolated from raw camel milk in Morocco. Comparative 16S rRNA gene sequencing assigned these bacteria to the genus Streptococcus with Streptococcus rupicaprae 2777-2-07(T) as their closest phylogenetic neighbour (95.9% and 95.7% similarity, respectively). 16S rRNA gene sequence similarity between the two strains was 96.7%. Although strains LMG 27682(T) and LMG 27684(T) shared a DNA-DNA hybridization value that corresponded to the threshold level for species delineation (68%), the two strains could be distinguished by multiple biochemical tests, sequence analysis of the phenylalanyl-tRNA synthase (pheS), RNA polymerase (rpoA) and ATP synthase (atpA) genes and by their MALDI-TOF MS profiles. On the basis of these considerable phenotypic and genotypic differences, we propose to classify both strains as novel species of the genus Streptococcus, for which the names Streptococcus moroccensis sp. nov. (type strain, LMG 27682(T)  = CCMM B831(T)) and Streptococcus rifensis sp. nov. (type strain, LMG 27684(T)  = CCMM B833(T)) are proposed. © 2014 IUMS.

2017-09-01

A novel streptomycete (strain HNM0141T) was isolated from tropical forest soil collected from Bawangling mountain of Hainan island, PR China and its taxonomic position was established in a polyphasic study. The organism had chemical and morphological properties consistent with its classification as a member of the Streptomyces violaceusnigerclade. On the basis of the results of 16S rRNA gene sequence analysis, HNM0141T showed highest similarity to Streptomyces malaysiensisCGMCC4.1900T (99.4 %), Streptomyces samsunensis DSM 42010T (98.9 %), Streptomyces yatensis NBRC 101000T (98.3 %), Streptomyces rhizosphaericus NBRC 100778T (98.0 %) and Streptomyces sporoclivatus NBRC 100767T (97.9 %). The strain formed a well-delineated subclade with S. malaysiensis CGMCC4.1900T and S. samsunensis DSM 42010T. The levels of DNA-DNA relatedness between HNM0141T and S. malaysiensis CGMCC4.1900T and S. samsunensis DSM 42010T were 62 and 44 %, respectively. On the basis of phenotypic and genotypic characteristics, HNM0141T represents a novel species in the S. violaceusnigerclade for which the name Streptomyces solisilvae sp. nov. is proposed. The type strain is HNM0141 T (=CCTCC AA 2016045T=KCTC 39905T).

DAQ Software Contributions, Absolute Scale Energy Calibration and Background Evaluation for the NOvA Experiment at Fermilab

Energy Technology Data Exchange (ETDEWEB)

Flumerfelt, Eric Lewis [Univ. of Tennessee, Knoxville, TN (United States)

2015-08-01

The NOvA (NuMI Off-axis v_e [nu_e] Appearance) Experiment is a long-baseline accelerator neutrino experiment currently in its second year of operations. NOvA uses the Neutrinos from the Main Injector (NuMI) beam at Fermilab, and there are two main off-axis detectors: a Near Detector at Fermilab and a Far Detector 810 km away at Ash River, MN. The work reported herein is in support of the NOvA Experiment, through contributions to the development of data acquisition software, providing an accurate, absolute-scale energy calibration for electromagnetic showers in NOvA detector elements, crucial to the primary electron neutrino search, and through an initial evaluation of the cosmic background rate in the NOvA Far Detector, which is situated on the surface without significant overburden. Additional support work for the NOvA Experiment is also detailed, including DAQ Server Administration duties and a study of NOvA’s sensitivity to neutrino oscillations into a “sterile” state.

A yellow Gram-stain-positive, non-motile, non-endospore -forming, spherical endophytic actinobacterium, designated strain AE-6(T), was isolated from the inner fleshy leaf tissues of Aloe barbadensis (Aloe vera) collected from Pune, Maharashtra, India. Strain AE-6(T) grew at high salt concentrations [10% (w/v) NaCl], temperatures of 15-41 °C and a pH range of 5-12. It showed highest (99.7%) 16S rRNA gene sequence similarity with Micrococcus yunnanensis YIM 65004(T) followed by Micrococcus luteus NCTC 2665(T) (99.6%) and Micrococcus endophyticus YIM 56238(T) (99.0%). Ribosomal protein profiling by MALDI-TOF/MS also showed it was most closely related to M. yunnanensis YIM 65004(T) and M. luteus NCTC 2665(T). Like other members of the genus Micrococcus, strain AE-6(T) had a high content of branched chain fatty acids (iso-C15:0 and anteiso-C15:0). MK-8(H2) and MK-8 were the predominant isoprenoid quinones. Cell wall analysis showed an 'A2 L-Lys-peptide subunit' type of peptidoglycan and ribose to be the major cell wall sugar. The DNA G+C content was 70 mol%. Results of DNA-DNA hybridization of AE-6(T) with its closest relatives from the genus Micrococcus produced a value of less than 70%. Based on the results of this study, strain AE-6(T) could be clearly differentiated from other members of the genus Micrococcus. We propose that it represents a novel species of the genus Micrococcus and suggest the name Micrococcus aloeverae sp. nov., with strain AE-6(T) ( = MCC 2184(T) = DSM 27472(T)) as the type strain of the species. © 2014 IUMS.

A Gram-negative, non-spore-forming, aerobic rods, strain YIC4121 T , was isolated from root nodule of Sesbania cannabina grown in Dongying (Yellow River Delta), Shandong Province, PR China. Based on phylogenetic analysis of 16 S rRNA gene sequences, strain YIC4121 T was assigned to the genus Agrobacterium with 99.7, 99.3, 99.0, 98.8 and 98.7% sequence similarities to Agrobacterium radiobacter LMG140 T , A. pusense NRCPB10 T , A. arsenijevicii KFB 330 T , A. nepotum 39/7 T and A. larrymoorei ATCC51759 T . Analysis of the concatenated housekeeping genes (recA-atpD-glnII), showed lower sequence similarities (≤94.6%) between strain YIC4121 T and other recognized Agrobacterium species. Strain YIC4121 T shared whole-genome average nucleotide identities (ANI) 87.94, 91.27 and 77.42%, with A. pusense NRCPB10 T , A. radiobacter LMG140 T and A. larrymoorei ATCC51759 T . The predominant cellular fatty acids were C 19:0 cyclo ω8c, summed feature 2 (C 12:0 aldehyde/unknown 10.9525), summed feature 8 (C 18:1 ω7c/C 18:1 ω6c), C 16:0 3 OH and C 16:0 . The G + C content of strain YIC4121 T was 59.80 mol%. Tween 80, lactulose, citric acid, α-ketoglutaric acid, glycyl-L-glutamic acid and 2, 3-butanediol could not be utilized as carbon source, distinguishing strain YIC4121 T from the other related species. Based on the distinctly genetic and phenotypic dissimilarity, a novel species Agrobacterium deltaense sp. nov. is proposed with YIC4121 T (=HAMBI 3654 T  = LMG 29283 T ) as the type strain.

A novel actinomycete, designated strain KC-035T, was isolated from soil collected from Krung Ching Waterfall National Park, Nakhon Si Thammarat Province, Thailand. Its taxonomic position was determined using a polyphasic approach. The strain had morphological and chemotaxonomic properties typical of members of the genus Streptomyces: flexuous spore chain; ll-diaminopimelic acid in the cell-wall peptidoglycan; MK-9(H8), MK-9(H6) and MK-9(H4) as menaquinones; diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylinositol and phosphatidylinositol mannoside as phospholipids; anteiso-C15 : 0, C16 : 0, iso-C16 : 0, iso-C15 : 0 and iso-C14 : 0 as major cellular fatty acids; and DNA G+C content of 72 mol%. 16S rRNA gene sequence analysis revealed that strain KC-035T showed high similarity to Streptomyces albiflavescens n20T (99.16 %) and Streptomyces siamensis KC-038T (98.43 %) as well as formed a monophyletic clade with them in the phylogenetic tree. On the basis of comparison of phenotypic properties and the low level of DNA-DNA relatedness, strain KC-035T could be distinguished from its closely related Streptomyces species and is considered to represent a novel species of the genus Streptomyces, for which the name Streptomyces krungchingensis sp. nov. is proposed. The type strain is KC-035T (=NBRC 110087T=KCTC 29503T=TISTR 2402T).

The radiosynthesis of {sup 99m}Tc-Novobiocin ({sup 99m}Tc-NBN) complex and its suitability as a radiotracer for infection imaging was assessed. The radiochemical purity (RCP) of the {sup 99m}Tc-NBN complex was determined using radio-TLC and radioactive HPLC and biodistribution was studied in artificially infected (A.I.) rats and rabbit, using single well gamma counter (SWGRC) interface with scalar count rate meter (SCRM) and Gamma Camera ({gamma}-CM). The maximum RCP observed for the preparation having 2 mg of NBN, 111 MBq of sodium pertechnetate (Na{sup 99m}TcO{sub 4}) and 125 {mu}L of SnF{sub 2} (1 {mu}g/{mu}L in 0.01 N HCl) at a pH 5.6 was 98.97{+-}0.40% and remained stable >90% up to 120 min. The activity of the {sup 99m}Tc-NBN in the infected muscle (TI) was significantly increased from 6.50{+-}0.15 to 19.00{+-}0.17% and decreased in the inflamed muscle (TII), normal muscle (NT), blood, liver, spleen, stomach and intestine within 120 min. The TI/NT and TII/NT ratios were 7.60{+-}1.08 and 1.60{+-}1.14. The Whole Body Static (WBS) images of A.I. rabbit were obtained at 30, 40, 50 and 60 min after the I.V. administration of 111 MBq of {sup 99m}Tc-NBN to the A.I. rabbit. The stability in saline and serum, higher TI/NT, lower TII/NT ratios and WBS images confirmed the feasibility of the {sup 99m}Tc-NBN complex as an infection imaging agent. (orig.)

The authors have examined the tumor affinity of various sup(99m)Tc-labelled radiopharmaceuticals to Ehrlich's tumor for the purpose of delineating human malignant neoplasm positively. The biologic distributions of sup(99m)Tc-Sn-diphosphonate (sup(99m)Tc-EHDP), sup(99m)Tc-Sn-dimercaptosuccinic acid (sup(99m)Tc-DMSA) and sup(99m)Tc-Sn-diethyl stilbestrol diphosphate (sup(99m)Tc-DSDP, sup(99m)Tc-Honvan) are included as the second report on the tumor affinity of Ehrlich-bearing mice. Tumor concentration of sup(99m)Tc-EHDP was lowest and the positive delineation of implanted tumor with sup(99m)Tc-EHDP was poorest in sequential images, though active accumulation in some soft tissues malignant neoplasms, breast cancer, and thyroid cancer, has been reported. Tumor concentration and the tumor-to-blood ratio of sup(99m)Tc-DMSA were not so high, contrary to our expectation that /sup 197/Hg-DMSA might show high tumor concentration and high tumor-to-blood ratio the same as /sup 197/Hg chlormerodrin of the renal scanning radiopharmaceuticals. Tumor concentration of sup(99m)Tc-DSDP was highest. The tumor-to-blood concentration ratio was lower than that of the above mentioned radiopharmaceuticals but the tumor-to-liver ratio and/or tumor-to-lung ratio was over 1.0 at the earlier time. Biologic distribution of sup(99m)Tc-DSDP was similar to that of /sup 32/P labeled DSDP. It is presumed that sup(99m)Tc is labeled at the phosphate ester of DSDP which is dephospholytated immediately by phospholylase in vivo following intravenous injection. Although it is not known precisely it may be assumed that the mechanism of accumulating sup(99m)Tc-DSDP in Ehrlich's tumor is related to the phospholylase activity in neoplasms.

A Gram-stain-negative, rod-shaped, non-motile and red-pink-pigmented bacterial strain, designated B1909T, was isolated from an ice core drilled from Muztagh Glacier on the Tibetan Plateau, China. A phylogenetic tree based on 16S rRNA gene sequences showed that strain B1909T formed a lineage within the genus Hymenobacter and was closely related to Hymenobacter xinjiangensis X2-1gT (96.16 % similarity) and Hymenobacter psychrotolerans Tibet-IIU11T (95.99 %). The predominant fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), summed feature 4 (iso-C17 : 1ω6c I/anteiso B), C16 : 1ω5c, anteiso-C15 : 0 and iso-C17 : 0 3-OH. The major menaquinone was MK-7. The major polar lipid was phosphatidylethanolamine. The DNA G+C content was 59 mol%. On the basis of the phenotypic, phylogenetic and chemotaxonomic data presented, strain B1909T is considered to represent a novel species of the genus Hymenobacter, for which the name Hymenobacterglacieicola sp. nov. is proposed; the type strain is B1909T (=JCM 30596T=CGMCC 1.12990T).

Osteomyelitis, which is characterized by progressive inflammatory destruction and new opposition of bone, is still a difficult infection to treat. The clinical diagnosis in late stages is achieved easily, but an early diagnosis is more challenging. Staphylococcus aureus is a common agent found in osteomyelitis and bone prostheses infection. Diagnosis by scintigraphy has advantages because it is a non-invasive procedure and is able to perform an early diagnosis even before anatomic changes. Thus, nuclear medicine could contribute to an accurate diagnosis since specific radiopharmaceuticals were developed. In this study, aptamers selected to Staphylococcus aureus were labeled with {sup 99m}Tc and used for bacteria identification in an osteomyelitis experimental model. The aptamers selected to S. aureus were directly labelled with {sup 99m}Tc and were evaluated by biodistribution studies. Wistar rats with intraosseous infection in the right paw were used. A random aptamer labelled with {sup 99m}Tc was as control. Six animals were used in each group. The aptamers labeled with {sup 99m}Tc were able to identify the infection foci caused by S. aureus displaying a target/non-target ratio of 2,23 ± 0,20, after 3 h. The control group presented a target/non-target ratio 1,08 ± 0.23. The results indicated that the radiolabeled aptamers were able to identify specifically the infection foci and they should be further explored for infection diagnosis by scintigraphy. (author)

Diversification of 99Mo/99mTc separation: non–fission reactor production of 99Mo as a strategy for enhancing 99mTc availability.

Science.gov (United States)

Pillai, Maroor R A; Dash, Ashutosh; Knapp, Furn F Russ

2015-01-01

This paper discusses the benefits of obtaining (99m)Tc from non-fission reactor-produced low-specific-activity (99)Mo. This scenario is based on establishing a diversified chain of facilities for the distribution of (99m)Tc separated from reactor-produced (99)Mo by (n,γ) activation of natural or enriched Mo. Such facilities have expected lower investments than required for the proposed chain of cyclotrons for the production of (99m)Tc. Facilities can receive and process reactor-irradiated Mo targets then used for extraction of (99m)Tc over a period of 2 wk, with 3 extractions on the same day. Estimates suggest that a center receiving 1.85 TBq (50 Ci) of (99)Mo once every 4 d can provide 1.48-3.33 TBq (40-90 Ci) of (99m)Tc daily. This model can use research reactors operating in the United States to supply current (99)Mo needs by applying natural (nat)Mo targets. (99)Mo production capacity can be enhanced by using (98)Mo-enriched targets. The proposed model reduces the loss of (99)Mo by decay and avoids proliferation as well as waste management issues associated with fission-produced (99)Mo.

Thermococcus strains TYST and TYT isolated from the Guaymas Basin hydrothermal vent site and previously described were compared by DNA-DNA hybridization analysis with the closest Thermococcus species in terms of physiology and nutritional aspects. On the basis of the new data and taking into consideration the molecular, physiological and morphological traits published previously, it is proposed that strains TYT and TYST should be classified as new species named Thermococcus aggregans sp. nov. and Thermococcus guaymasensis sp. nov., respectively. The type strain of T. aggregans is strain TYT (= DSM 10597T) and the type strain of T. guaymasensis is strain TYST (= DSM 11113T).

Full Text Available Sharon gen. nov. is here described to include Asaphes? amoenus Philippi, 1861 comb. nov. from Chile. A redescription of the species is based on the female holotype and material from different geographic locations. Candèze (1891 placed Asaphes amoenus and Parasaphes elegans in the suprageneric group Asaphites. We discuss differences between Sharon gen. nov. and Hemicrepidius Germar, 1839, where Asaphes amoenus was later placed by Blackwelder (1944. Based on morphological characters, Sharon gen. nov. appears to be related to Parasaphes Candèze, 1881, Wynarka Calder, 1986, and Tasmanelater Calder, 1996, all from Australia, suggesting Gondwanan relationships.

The characterization of five Iranian isolates, four from hospital haemodialysis water and one from the sputum of a patient, led to the detection of a novel mycobacterium species. The strains were characterized by mucoid colonies developing in 3-5 days at temperatures ranging from 25 to 37 °C. The biochemical test pattern was unremarkable while the HPLC profile of mycolic acids resembled that of Mycobacterium fortuitum. The sequences of three major housekeeping genes (16S rRNA, hsp65 and rpoB) were unique and differed from those of any other mycobacterium. Mycobacterium brisbanense, which is the species that shared the highest 16S rRNA gene sequence similarity (99.03 %), was distinct, as shown by the average nucleotide identity and by the genome to genome distance values (91.05 and 43.10 %, respectively). The strains are thus considered to represent a novel species of the genus Mycobacterium, for which the name Mycobacterium aquaticum sp. nov. is proposed. The type strain is RW6T (=DSM 104277T=CIP111198T).

The HOLA intervention was a lay health advisor intervention designed to reduce the disproportionate HIV burden borne by Latino sexual and gender identity minorities (gay, bisexual, and other men who have sex with men, and transgender persons) living in the United States. Process evaluation data were collected for over a year of intervention implementation from 11 trained Latino male and transgender lay health advisors (Navegantes) to document the activities each Navegante conducted to promote condom use and HIV testing among his or her 8 social network members enrolled in the study. Over 13 months, the Navegantes reported conducting 1,820 activities. The most common activity was condom distribution. Navegantes had extensive reach beyond their enrolled social network members, and they engaged in health promotion activities beyond social network members enrolled in the study. There were significant differences between the types of activities conducted by Navegantes depending on who was present. Results suggest that lay health advisor interventions reach large number of at-risk community members and may benefit populations disproportionately impacted by HIV. PMID:25416309

A phoslactomycin-producing actinomycete, designated strain NEAU-ML8T, was isolated from a millipede (Kronopolites svenhedind Verhoeff) and characterized using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain NEAU-ML8T belongs to the genus Streptomyces with the highest sequence similarities to Streptomyces lydicus NBRC 13058T (99.39 %) and Streptomyces chattanoogensis DSM 40002T (99.25 %). The maximum-likelihood phylogenetic tree based on 16S rRNA gene sequences showed that the isolate formed a distinct phyletic line with NBRC 13058T and S. chattanoogensis DSM 40002T. This branching pattern was also supported by the tree rconstructed with the neighbour-joining method. A combination of DNA-DNA hybridization experiments and phenotypic tests were carried out between strain NEAU-ML8T and its phylogenetically closely related strains, which further clarified their relatedness and demonstrated that NEAU-ML8T could be distinguished from NBRC 13058T and S. chattanoogensis DSM 40002T. Therefore, it is concluded that strain NEAU-ML8T can be classified as representing a novel species of the genus Streptomyces, for which the name Streptomyces kronopolitis sp. nov. is proposed. The type strain is NEAU-ML8T (=DSM 101986T=CGMCC 4.7323T).

2014-01-01

Technetium-99m (T 1/2 = 6.02h; 140.51 keV (89%)) is the most useful radioisotope in diagnostic nuclear medicine. More than 80% of all diagnostic procedures done worldwide in nuclear medicine centre are performed with 99m Tc. Worldwide crisis of fission 99 Mo based generator in recent past had put the nuclear medicine fraternity in very harsh situation. In order to have an indigenous solution of this problem, we tried to develop a computer controlled semi automated 99 Mo/ 99m Tc generator using MEK solvent extraction technique, which utilizes abundantly available 99 Mo produced by (n,γ) reaction in BARC reactors. The aim of this work is to provide a more reliable, computer controlled module (TCM- AUTOSOLEX) for the recovery of pharmaceutical grade 99m Tc from low specific activity 99 Mo based on solvent extraction methodology

Sphyrna gilberti sp. nov. is described based on 54 specimens collected in the coastal waters of South Carolina, U.S.A. Morphologically, S. gilberti sp. nov. is separable from S. lewini (Griffith & Smith 1834) only in the number of precaudal vertebrae. Due to rarity of specimens and the highly migratory behavior of most sphyrnids, the range of S. gilberti sp. nov. is unknown.

Hind, Katharine R; Gabrielson, Paul W; P Jensen, Cassandra; Martone, Patrick T

Molecular phylogenetic analyses of 18S rDNA (SSU) gene sequences confirm the placement of Crusticorallina gen. nov. in Corallinoideae, the first nongeniculate genus in an otherwise geniculate subfamily. Crusticorallina is distinguished from all other coralline genera by the following suite of morpho-anatomical characters: (i) sunken, uniporate gametangial and bi/tetrasporangial conceptacles, (ii) cells linked by cell fusions, not secondary pit connections, (iii) an epithallus of 1 or 2 cell layers, (iv) a hypothallus that occupies 50% or more of the total thallus thickness, (v) elongate meristematic cells, and (vi) trichocytes absent. Four species are recognized based on rbcL, psbA and COI-5P sequences, C. painei sp. nov., the generitype, C. adhaerens sp. nov., C. nootkana sp. nov. and C. muricata comb. nov., previously known as Pseudolithophyllum muricatum. Type material of Lithophyllum muricatum, basionym of C. muricata, in TRH comprises at least two taxa, and therefore we accept the previously designated lectotype specimen in UC that we sequenced to confirm its identity. Crusticorallina species are very difficult to distinguish using morpho-anatomical and/or habitat characters, although at specific sites, some species may be distinguished by a combination of morpho-anatomy, habitat and biogeography. The Northeast Pacific now boasts six coralline endemic genera, far more than any other region of the world. © 2016 Phycological Society of America.

Lactococcus lactis subsp. tructae subsp. nov. isolated from the intestinal mucus of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss).

The species Lactococcus lactis currently includes three subspecies; L. lactis subsp. lactis and L. lactis subsp. cremoris, isolated from milk sources, and L. lactis subsp. hordniae, isolated from the leafhopper Hordnia circellata. In this study, three strains, designated L105(T), I3 and L101, were isolated from the intestinal mucus of brown trout (Salmo trutta) and rainbow trout (Oncorhynchus mykiss). These strains were closely related to members of the species Lactococcus lactis. Strain L105(T) showed 99.4 % 16S rRNA gene sequence similarity to that of the type strains L. lactis subsp. lactis NCDO 604(T) and L. lactis subsp. hordniae NCDO 2181(T) and showed 99.9 % similarity to the type strain Lactococcus lactis subsp. cremoris NCDO 607(T). Analysis of two housekeeping genes, rpoB and recA, confirmed the close relationship between the novel strains and L. lactis subsp. cremoris with similarities of 99.3 and 99.7 %, respectively. The three strains could, however, be differentiated from their closest relatives on the basis of several phenotypic characteristics, as was the case for L. lactis subsp. lactis and L. lactis subsp. hordniae, which were also closely related on the basis of 16S rRNA, rpoB and recA gene sequence similarities. The strains isolated in this study represent a new subspecies, for which the name Lactococcus lactis subsp. tructae subsp. nov. is proposed. The type strain is L105(T) ( = LMG 24662(T)  = DSM 21502(T)).

A taxonomic study was carried out on strain GCS-AE-31(T), which was isolated from a phenol-degrading consortium, enriched from coking wastewater activated sludge of the Beijing Shougang Company Limited during the screening of phenol-degrading bacteria. Cells of strain GCS-AE-31(T) were Gram-stain-negative, short rods, motile by gliding, oxidase- and catalase-positive. Growth was observed at salinities of 0-3% and at temperatures of 10-37 °C. On the basis of 16S rRNA gene sequence similarity, strain GCS-AE-31(T) was most closely related to Pedobacter saltans LMG 10337(T) (96.17%), but it showed low similarity to all other species of the genus Pedobacter (89.28-92.45%). It also showed low 16S rRNA gene similarity to all other species of the family Sphingobacteriaceae (87.25-92.45%) examined. The dominant fatty acids were iso-C(15 : 0), summed feature 3 (C(16 : 1)ω7c/C(16 : 1)ω6c), anteiso-C(15 : 0) and iso-C(17 : 0) 3-OH. The menaquinones were MK-7 (95.5%) and MK-6 (4.5%). The polar lipids were phosphatidylethanolamine, three aminolipids and three unknown phospholipids. Sphingolipid was present. The G+C content of the chromosomal DNA was 36.2 mol%. According to its phylogenetic position and phenotypic traits, the novel strain could not be assigned to the genus Pedobacter; it should be classified as representing a novel species of a novel genus in the family Sphingobacteriaceae, for which the name Pseudopedobacter beijingensis gen. nov., sp. nov. is proposed (type strain GCS-AE-31(T) = MCCC 1A01299(T) = CGMCC 1.12329(T) = LMG 27180(T)).

99m Tc is the most commonly used radionuclide in the field of diagnostic imaging, a noninvasive method intended to diagnose a disease, assess the disease state and monitor the effects of treatments. Annually, the use of 99m Tc, covers about 85% of nuclear medicine applications. This isotope releases gamma rays at about the same wavelength as conventional X-ray diagnostic equipment, and owing to its short half-life (t ½  = 6 h) is ideal for diagnostic nuclear imaging. A patient can be injected with a small amount of 99m Tc and within 24 h almost 94% of the injected radionuclide would have decayed and left the body, limiting the patient's radiation exposure. 99m Tc is usually supplied to hospitals through a 99 Mo/ 99m Tc radionuclide generator system where it is produced from the β decay of the parent nuclide 99 Mo (t ½  = 66 h), which is produced in nuclear reactors via neutron fission. Recently, the interruption of the global supply chain of reactor-produced 99 Mo, has forced the scientific community to investigate alternative production routes for 99m Tc. One solution was to consider cyclotron-based methods as potential replacement of reactor-based technology and the nuclear reaction 100 Mo(p,2n) 99m Tc emerged as the most worthwhile approach. This review reports some achievements about 99m Tc produced by medical cyclotrons. In particular, the available technologies for target design, the most efficient extraction and separation procedure developed for the purification of 99m Tc from the irradiated targets, the preparation of high purity 99m Tc radiopharmaceuticals and the first clinical studies carried out with cyclotron produced 99m Tc are described.

Williams, C.C.; Kereiakes, J.G.; Grossman, L.W.

1981-01-01

A study was performed to determine the accuracy of 99 Mo measurements using three commercial dose calibrators with their 99 Mo assay shields. One 99 Mo assay shield allowed excessive penetration by the lower energy /sup 99m/Tc photons, resulting in the calibrator's falsely high interpretation of the activity of 99 Mo present in the high-activity /sup 99m/Tc eluates. All three calibrators performed adequately with a National Bureau of Standards 99 Mo standard in equilibrium with /sup 99m/Tc. By using low-activity aliquots of 99 Mo and /sup 99m/Tc, a low-level linearity test was performed. Only one of the calibrators was found to reflect accurately the activity of 99 Mo present under all conditions tested

The medical student population is believed to be at an increased risk for sleep deprivation. Little is known about students' perceptions towards sleep deprivation and its relationship to academic performance. The aim of study is to explore the perceptions of medical students and their academic advisors about sleep deprivation and its relationship to academic performance. The study took place at Alfaisal University, College of Medicine, Riyadh, Saudi Arabia. An online, anonymous, cross-sectional, self-rating survey was administered to first-, third-year students and their academic advisors. Two-tailed Mann-Whitney U test was used to compare the mean 5-point Likert scale responses between students according to gender, academic year and cumulative grade point average (cGPA). A total of 259 students and 21 academic advisors participated in the survey (response rates: 70.6 and 84%, respectively). The vast majority of students agreed that sleep deprivation negatively affects academic performance (78.8%) and mood (78.4%). Around 62.2 and 73.7% of students agreed that the demanding medical curriculum and stress of final exams lead to sleep deprivation, respectively. While 36.7% of students voiced the need for incorporation of curricular separate courses about healthy sleep patterns into medical curriculum, a much greater proportion of students (45.9%) expressed interest in extracurricular activities about healthy sleep patterns. Interestingly, only 13.5% of students affirmed that they were counselled about sleep patterns and academic performance by their academic advisors. There were several statistically significant differences of means of students' perceptions according to gender, academic year and cGPA. Despite almost all academic advisors (95.5%) asserted the importance of sleep patterns to academic performance, none (0%) inquired about sleep patterns when counselling students. Nineteen academic advisors (90.5%) recommended incorporation of sleep patterns related

Sixteen isolates of Gram-reaction-negative, motile, violet-pigmented bacteria were isolated from Sphagnum bogs in West Virginia and Maine, USA. 16S rRNA gene sequences and fatty acid analysis revealed a high degree of relatedness among the isolates, and genome sequencing of two isolates, IIBBL 14B-1T and IIBBL 37-2 (from West Virginia and Maine, respectively), revealed highly similar genomic sequences. The average nucleotide identity (gANI) calculated for these two isolates was found to be in excess of 99 %, but did not exceed 88 % when comparing either isolate with genomic sequences of Chromobacterium violaceum ATCC 12472T, C. haemolyticum DSM 19808T, C. piscinae ND17, C. subtsugae PRAA4-1T, C. vaccinii MWU205T or C. amazonense CBMAI 310T. Collectively, gANI and 16S rRNA gene sequence comparisons suggested that isolates IIBBL 14B-1T and IIBBL 37-2 were most closely related to C. subtsugae, but represented a distinct species. We propose the name Chromobacterium sphagni sp. nov. for this taxon; the type strain is IIBBL 14B-1T (=NRRL B-67130T=JCM 31882T).

Subtraction scintigraphy of the liver with Ga-67-citrate and Tc-99m-colloid was performed for the radionuclide image diagnosis of intrahepatic masses, especially hepatoma. In this method the Tc-99m image was subtracted from the Ga-67 image. After normalizing both images, 4 different factors (0.6, 0.8, 1.0, and 1.2) were applied to the Tc-99m image before the subtraction. Finally, 4 subtraction images with different contrasts were obtained in one X-ray film. This method was found to be very useful in the assessment of intrahepatic focal accumulation of Ga-67, especially in cases with hepatoma, because it eliminated the uncertainty in the former method in which only visual judgment was done

Two Gram-stain-negative bacterial strains, SAP-32T and SAP-36, were isolated from sap drawn from the Acer pictum from Mount Halla in Jeju, Republic of Korea. The organisms were strictly aerobic, non-sporulating, motile rods and showed growth at 10-30 °C, pH 7-8 and with 0-2 % NaCl. The major isoprenoid quinone was Q-8. The predominant fatty acids were C16 : 0, cyclo-C17 : 0, summed feature 3 and C18 : 0. The polar lipids contained phosphatidylcholine, phosphatidylethanolamine, phosphatidylglycerol, an unknown aminophosphoglycolipid, an unknown glycolipid, an unknown phospholipid and two unknown lipids. The DNA G+C content was 64.4 mol%. The results of phylogenetic analyses based on 16S rRNA gene sequences indicated that SAP-32T and SAP-36 formed a distinct cluster with members of the genus Pigmentiphaga within the family Alcaligenaceae. Both strains showed 16S rRNA gene sequence similarity of 100 % to each other. The closest relatives of the isolates were Pigmentiphaga daeguensis (97.08 % sequence similarity), Pigmentiphaga kullae (97.01 %) and Pigmentiphaga litoralis (96.73 %). On the basis of data from phenotypic, chemotaxonomic and phylogenetic analyses, SAP-32T (=KCTC 52619T=DSM 104039T) and SAP-36 (=KCTC 52620=DSM 104072) represent members of a novel species of the genus Pigmentiphaga, for which the name Pigmentiphaga aceris sp. nov. is proposed.

Geffré, Anne; Concordet, Didier; Braun, Jean-Pierre; Trumel, Catherine

2011-03-01

International recommendations for determination of reference intervals have been recently updated, especially for small reference sample groups, and use of the robust method and Box-Cox transformation is now recommended. Unfortunately, these methods are not included in most software programs used for data analysis by clinical laboratories. We have created a set of macroinstructions, named Reference Value Advisor, for use in Microsoft Excel to calculate reference limits applying different methods. For any series of data, Reference Value Advisor calculates reference limits (with 90% confidence intervals [CI]) using a nonparametric method when n≥40 and by parametric and robust methods from native and Box-Cox transformed values; tests normality of distributions using the Anderson-Darling test and outliers using Tukey and Dixon-Reed tests; displays the distribution of values in dot plots and histograms and constructs Q-Q plots for visual inspection of normality; and provides minimal guidelines in the form of comments based on international recommendations. The critical steps in determination of reference intervals are correct selection of as many reference individuals as possible and analysis of specimens in controlled preanalytical and analytical conditions. Computing tools cannot compensate for flaws in selection and size of the reference sample group and handling and analysis of samples. However, if those steps are performed properly, Reference Value Advisor, available as freeware at http://www.biostat.envt.fr/spip/spip.php?article63, permits rapid assessment and comparison of results calculated using different methods, including currently unavailable methods. This allows for selection of the most appropriate method, especially as the program provides the CI of limits. It should be useful in veterinary clinical pathology when only small reference sample groups are available. ©2011 American Society for Veterinary Clinical Pathology.

Data Driven Trigger Design and Analysis for the NOvA Experiment

This thesis primarily describes analysis related to studying the Moon shadow with cosmic rays, an analysis using upward-going muons trigger data, and other work done as part of MSc thesis work conducted at Fermi National Laboratory. While at Fermilab I made hardware and software contributions to two experiments - NOvA and Mu2e. NOvA is a neutrino experiment with the primary goal of measuring parameters related to neutrino oscillation. This is a running experiment, so it's possible to provide analysis of real beam and cosmic data. Most of this work was related to the Data-Driven Trigger (DDT) system of NOvA. The results of the Upward-Going muon analysis was presented at ICHEP in August 2016. The analysis demonstrates the proof of principle for a low-mass dark matter search. Mu2e is an experiment currently being built at Fermilab. Its primary goal is to detect the hypothetical neutrinoless conversion from a muon into an electron. I contributed to the production and tests of Cathode Strip Chambers (CSCs) which are required for testing the Cosmic Ray Veto (CRV) system for the experiment. This contribution is described in the last chapter along with a short description of the technical work provided for the DDT system of the NOvA experiment. All of the work described in this thesis will be extended by the next generation of UVA graduate students and postdocs as new data is collected by the experiment. I hope my eorts of have helped lay the foundation for many years of beautiful results from Mu2e and NOvA.

Advanced networking technologies and services have been rapidly developed and deployed to facilitate such massive data transfer. However, these technologies and services have not been fully utilized mainly because their use typically requires significant domain knowledge and in many cases application users are even not aware of their existence. By leveraging the functionalities of an existing Network-Aware Data Movement Advisor (NADMA) utility, we propose a new Workflow-based Intelligent Network Data Movement Advisor (WINDMA) with end-to-end performance optimization for this DOE funded project. This WINDMA system integrates three major components: resource discovery, data movement, and status monitoring, and supports the sharing of common data movement workflows through account and database management. This system provides a web interface and interacts with existing data/space management and discovery services such as Storage Resource Management, transport methods such as GridFTP and GlobusOnline, and network resource provisioning brokers such as ION and OSCARS. We demonstrate the efficacy of the proposed transport-support workflow system in several use cases based on its implementation and deployment in DOE wide-area networks.

Study of methodologies for quality control of 99Mo used in 99Mo/99mTc generators

International Nuclear Information System (INIS)

Said, Daphne de Souza

2016-01-01

99m Tc is the most used radionuclide in nuclear medicine. In Brazil, the 99 Mo/ 99m Tc generators are exclusively produced by Radiopharmacy Center at IPEN-CNEN/ SP, by importing 99 Mo from different suppliers. 99 Mo (t 1/2 = 66 h) is a fission product of 235 U and it can have radionuclidic impurities that are prejudicial for human health. For safe use of generators, it is necessary to perform the evaluation of 99 Mo by quality control tests in order to assess if 99 Mo complies with the specifications. The European Pharmacopoeia (EP) presents a monograph for evaluation of the quality of the [ 99 Mo] solution as sodium molybdate,that is used as raw material for 99 Mo/ 99m Tc generators production, including specification parameters (identification, radiochemical purity and radionuclidic purity), analysis methods and limits. However, it has been observed difficulties on the execution and implementation of these methods by the generators producers, with a few literature about this subject, probably due to complexity of the proposed methods. In this work, many quality control parameters of 99 Mo described in the EP monograph were evaluated. Separation methods for 99M o from its radionuclidic impurities by solid phase extraction (SPE) and TLC were studied. After SPE separation, the quantification of metals by ICP-OES to evaluate the percentage of retention of Mo and the percentage of recovery of Ru, Te and Sr using different types of cartridges were proposed, replacing radiotracers use. It was observed that the specific type of SPE cartridge recommended by the EP for separation of 99 Mo presented low recoveries for Ru, compared to other available anion exchange SPE cartridges. 99 Mo samples from different worldwide suppliers were analyzed. It was observed that quantification of 103 Ru in 99 Mo samples with decay time higher than 4 weeks is possible. An alternative method for separation of 131 I from 99 Mo showed promising results by TLC. The quantification of beta and

Three thermo-tolerant halophilic archaeal strains, SR-441T, SR-412 and SR-188, were isolated from commercial salt samples. Cells were non-motile pleomorphic rod-shaped, and stained Gram-negative. Colonies were pink-pigmented. The three strains were able to grow with 1.7-4.6 M NaCl (optimum, 2.5 M), at pH 6.5-9.0 (optimum, pH 8.0) and at 35-60 °C (optimum, 45 °C). The orthologous 16S rRNA gene sequence similarities amongst the three strains were 98.8-99.3 %, and the level of DNA-DNA relatedness was 71-74 and 72-75 % (reciprocally). The closest relative was Halopiger aswanensis JCM 11628T with 98.6 %-99.1 % similarity in the orthologous 16S rRNA gene sequences, followed by two more Halopiger species, Halopiger xanaduensis JCM 14033T (98.5 %-99.1 %) and Halopiger salifodinae JCM 9578T (95.5 %-95.6 %). DNA-DNA relatednesses between the three strains and H. aswanensis JCM 11628T and H. xanaduensis JCM 14033T were 61 and 54 %, respectively. The polar lipids of the three novel strains were phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, and bis-sulfated diglycosyl archaeol-1. The most distinctive feature of the three strains was the ability to grow at 60 °C, while the maximum growth temperature of H. aswanensis is 55 °C. Based on phenotypic and phylogenetic analyses, the isolates are considered to represent a novel species of the genus Halopiger, for which the name Halopiger thermotolerans sp. nov. is proposed. The type strain is SR-441T (=JCM 19583T=KCTC 4248T) isolated from solar salt produced in Australia. SR-412 (=JCM 19582) and SR-188 (=JCM 19581) isolated from commercial salt samples are additional strains of the species.

2003-01-01

Production of high-specific activity molybdenum-99 and 99 Mo/ 99m Tc Generators in Indonesia commenced when a new production facility supported by the presence of a 30 MW multipurpose reactor (RSG-GAS) was established in Serpong in 1990. This report describes the current production and supply of molybdenum-99m devoted mainly to fulfill the domestic demands in supplying 99 Mo/ 99m Tc Generators. Recent development on the use of LEU (Low Enriched Uranium) targets for replacing current HEU (High Enriched Uranium) targets in the production of 99 Mo will be reviewed briefly. (author)

Nocardia kroppenstedtii sp. nov., an actinomycete isolated from a lung transplant patient with a pulmonary infection.

LENUS (Irish Health Repository)

Jones, Amanda L

2014-03-01

A novel actinomycete, strain N1286(T), isolated from a lung transplant patient with a pulmonary infection, was provisionally assigned to the genus Nocardia. The strain had chemotaxonomic and morphological properties typical of members of the genus Nocardia and formed a distinct phyletic line in the Nocardia 16S rRNA gene tree. Isolate N1286(T) was most closely related to Nocardia farcinica DSM 43665(T) (99.8% gene sequence similarity) but could be distinguished from the latter by the low level of DNA-DNA relatedness. These strains were also distinguishable on the basis of a broad range of phenotypic properties. It is concluded that strain N1286(T) represents a novel species of the genus Nocardia for which the name Nocardia kroppenstedtii sp. nov. is proposed. The type strain is N1286(T) ( = DSM 45810(T) = NCTC 13617(T)).

The name 'Mycobacterium alsiense', although reported in 2007, has not been validly published. Polyphasic characterization of three available strains of this species led us to the conclusion that they represent a distinct species within the genus Mycobacterium. The proposed novel species grows slowly and presents pale yellow-pigmented colonies. Differentiation from other mycobacteria is not feasible on the basis of biochemical and cultural features alone while genetic analysis, extended to eight housekeeping genes and one spacer region, reveals its clear distinction from all other mycobacteria. Mycobacterium asiaticum is the most closely related species on the basis of 16S rRNA gene sequences (similarity 99.3 %); the average nucleotide identity between the genomes of the two species is 80.72 %, clearly below the suggested cut-off (95-96 %). The name Mycobacterium alsense sp. nov. is proposed here for the novel species and replaces the name 'M. alsiense', ex Richter et al. 2007, given at the time of isolation of the first strain. The type strain is TB 1906T ( = DSM 45230T = CCUG 56586T).

This paper examines tourists’ knowledge sharing behavior in social media. Based on social capital theory, we aim to examine the effects of three dimensions of social capital—structural (social interaction ties), cognitive (shared vision), and relational (trust)—for two different types of social media: Facebook and TripAdvisor. We propose a structural model that connects an antecedent (homophily) and a consequence (knowledge sharing through posting) of these main dimensions of social capital. ...

Measurement of Mo-99 column activity in the evaluation of Mo-99/Tc-99m generator

International Nuclear Information System (INIS)

Kuster, Z.

1994-01-01

In order to calculate the real elution efficiency of Mo-99/Tc-99m generator the Mo-99 content on the column has to be previously determined. As found in this work, the external measurement of Mo-99-column activity by means of Geiger-Mueller counter is a simple, fast and reliable method. Generally, Mo-99-column is placed slightly out of the center of the generator; therefore the externally measured flux of photons (φ) is an angular-dependent function. If the thickness of the lead container is radially uniform, the flux measured at some distance from the generator (which is rotated in 2π/3 steps) is given by the equation φ = A (1 + Bcos (α-2π(i - 2)/3)) -1 , i=1,2 or 3 (Eq.1) where A is a numerical constant depending on the Mo-99-column activity, B is a numerical constant depending on the Mo-99- column position within the lead container, the angle α depends on the initial orientation of the generator. A total of 20 generator were studied. The measured Mo-99-column activities (Capintec dose calibrator) were in the range 13.1- 35.11 GBq. Contrary to the findings of Vinberg and Kristensen (Eur J Nucl Med 1/1976(219), values of A (Eq. 1) are in good correlation (r 2 =0.9794) with the measured Mo-99-column activities. (author)

Two populations of Rivularia-like cyanobacteria were isolated from ecologically distinct and biogeographically distant sites. One population was from an unpolluted stream in the Kola Peninsula of Russia, whereas the other was from a wet wall in the Grand Staircase-Escalante National Monument, a desert park-land in Utah. Though both were virtually indistinguishable from Rivularia in field and cultured material, they were both phylogenetically distant from Rivularia and the Rivulariaceae based on both 16S rRNA and rbcLX phylogenies. We here name the new cryptic genus Cyanomargarita gen. nov., with type species C. melechinii sp. nov., and additional species C. calcarea sp. nov. We also name a new family for these taxa, the Cyanomargaritaceae. © 2017 Phycological Society of America.

The Convolutional Visual Network for Identification and Reconstruction of NOvA Events

Energy Technology Data Exchange (ETDEWEB)

Psihas, Fernanda [Indiana U.

2017-11-22

In 2016 the NOvA experiment released results for the observation of oscillations in the vμ and ve channels as well as ve cross section measurements using neutrinos from Fermilab’s NuMI beam. These and other measurements in progress rely on the accurate identification and reconstruction of the neutrino flavor and energy recorded by our detectors. This presentation describes the first application of convolutional neural network technology for event identification and reconstruction in particle detectors like NOvA. The Convolutional Visual Network (CVN) Algorithm was developed for identification, categorization, and reconstruction of NOvA events. It increased the selection efficiency of the ve appearance signal by 40% and studies show potential impact to the vμ disappearance analysis.

There was little evidence that Tc-99m labeled ciprofloxacin (Infecton) located inside of bacteria. Antimicrobial activity of infecton could be an indirect evidence of its location. We compared in vitro antimicrobial ativities of infecton and ciprofloxacin. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of Infecton and ciprofloxacin against three standard strains of bacteria, Staphylococcus aureus ATCC 29213, Escherichia coli ATCC 25922 and Pseudomonas aeruginosa ATCC 27853 were measured using modified broth macrodilution techniques and pour plate methods, respectively. Data were expressed as mean ±SE (range). MICs of infecton and ciprofloxacin were 1.12 ±0.20 (0.8 ∼ 1.6) μg/ml and 0.36±0.04 (0.2∼0.4) μg/ml for S. aureus, 0.03±0.005 (0.025 ∼0.05) μg/ml and 0.011±0.001 (0.006∼0.012) μg/ml for E. coli, and 0.96±0.16 (0.8 ∼1.6) μg/ml and 0.56±0.098(0.4 ∼0.8) μg/ml for P. aeruginosa, respectively. MBCs of Infecton and ciprofloxacin were 2.56±0.39 (1.6∼3.2 )μg/ml and 0.88 ±0.2 (0.4 ∼1.6) μg/ml for S, aureus, 0.04±0.06(0.025∼0.05) μg/ml and 0.02 ±0.01(0.025∼0.05) μg/ml for E. Coli, and 2.24±0.39 (1.6 ∼ 3.2) μg/ml and 1.44 ±0.16 (0.8 ∼1.6)μg/ml for P. aeruginosa, respectively. Although both MICs and MBCs of infecton were higher than those of ciprofloxacin, all three standard bacterial strains were sensitive to infecton. It could be an indirect evidence that Tc-99m infecton be a specific imaging agent for bacterial infecton

Event Reconstruction in the NOvA Experiment

Energy Technology Data Exchange (ETDEWEB)

Behera, Biswaranjan [Indian Inst. Tech., Hyderabad; Davies, Gavin [Indiana U.; Psihas, Fernanda [Indiana U.

2017-10-10

The NOvA experiment observes oscillations in two channels (electron-neutrino appearance and muon-neutrino disappearance) using a predominantly muon-neutrino NuMI beam. The Near Detector records multiple overlapping neutrino interactions in each event and the Far Detector has a large background of cosmic rays due to being located on the surface. The oscillation analyses rely on the accurate reconstruction of neutrino interactions in order to precisely measure the neutrino energy and identify the neutrino flavor and interaction mode. Similarly, measurements of neutrino cross sections using the Near Detector require accurate identification of the particle content of each interaction. A series of pattern recognition techniques have been developed to split event records into individual spatially and temporally separated interactions, to estimate the interaction vertex, and to isolate and classify individual particles within the event. This combination of methods to achieve full event reconstruction in the NOvA detectors has discussed.

Academic involvement in shift technical advisor training for the utilities

One of the clearest conclusions reached of nearly every commission and panel formed in response to the Three Mile Island accident was the desirability of upgrading the educational background of those persons with direct operational responsibility in a nuclear power plant. The long term objective is for all shift supervisors to have engineering degrees as well as NRC senior operating licenses. In the interim, the utilities are required to provide in-depth engineering expertise on every shift in the person of a Shift Technical Advisor (STA). The training of STA's is complicated by the requirement to have college level instruction in plant specific topics which are not typically included in the curricula of degree-granting instructions. One possible response to this challenge is presented

Strain ZS314(T) was isolated from a sandy intertidal sediment sample collected from the coastal area off the Chinese Antarctic Zhongshan Station, east Antarctica (6 9° 22' 13″ S 76 ° 21' 41″ E). The cells were Gram-positive, motile, short rods. The temperature range for growth was 0-26 °C and the pH for growth ranged from 5 to 10, with optimum growth occurring within the temperature range 18-23 °C and pH range 6.0-8.0. Growth occurred in the presence of 0-6 % (w/v) NaCl, with optimum growth occurring in the presence of 2-4 % (w/v) NaCl. Strain ZS314(T) had MK-10 as the major menaquinone and anteiso-C(15 : 0), iso-C(16 : 0) and anteiso-C(17 : 0) as major fatty acids. The cell-wall peptidoglycan type was B2β with ornithine as the diagnostic diamino acid. The major polar lipids were diphosphatidylglycerol and phosphatidylglycerol. The genomic DNA G+C content was approximately 67 mol%. Phylogenetic analysis based on 16S rRNA gene sequence similarity showed that strain ZS314(T) represents a new lineage in the family Microbacteriaceae. On the basis of the phylogenetic analyses and phenotypic characteristics, a new genus, namely Marisediminicola gen. nov., is proposed, harbouring the novel species Marisediminicola antarctica sp. nov. with the type strain ZS314(T) (=DSM 22350(T) =CCTCC AB 209077(T)).

SDS-PAGE of total bacterial proteins was applied to the classification of 25 Sudanese and five Kenyan strains isolated from the root nodules of Acacia senegal and Prosopis chilensis. Twenty strains were also studied by multilocus enzyme electrophoresis (MLEE) and the whole 16S rRNA gene was sequenced from two strains representing the two major clusters. These results, together with the previously reported numerical taxonomy analysis, pulsed-field gel electrophoresis studies, DNA-DNA dot-blot hybridization, genomic fingerprinting using repetitive sequence-based PCR, DNA base composition analysis, DNA-DNA reassociation analysis, partial sequencing of the 16S rRNA gene and RFLP analysis of the amplified 16S rRNA gene, showed that all 30 strains belong to the genus Sinorhizobium. Two of the strains grouped with Sinorhizobium saheli and seven with Sinorhizobium terangae, while the rest did not cluster with any of the established species. The majority of the strains formed two phenotypically and genotypically distinct groups and we therefore propose that these strains should be classified as two new species, Sinorhizobium arboris sp. nov. and Sinorhizobium kostiense sp. nov.

A Gram-staining-negative, facultatively aerobic bacterium, strain XCD-X85(T), was isolated from Xiaochaidan Lake, a salt lake (salinity 9.9%, w/v) in Qaidam basin, Qinghai province, China. Its taxonomic position was determined by using a polyphasic approach. Cells of strain XCD-X85(T) were non-endospore-forming rods, 0.4-0.6 μm wide and 1.0-1.6 μm long, and motile by means of a single polar flagellum. Strain XCD-X85(T) was catalase- and oxidase-positive. Growth was observed in the presence of 0-12.0% (w/v) NaCl (optimum, 1.0-2.0%) and at 4-35 °C (optimum, 25-30 °C) and pH 6.5-10.5 (optimum, pH 8.0-8.5). Strain XCD-X85(T) contained (>10%) summed feature 8 (C18 : 1ω7c and/or C18 : 1ω6c), C12 : 0, C16 : 0 and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c) as the predominant fatty acids. The major respiratory quinone was ubiquinone 9 (Q-9). The major polar lipids were phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol. The DNA G+C content was 57.4 mol%. Phylogenetic trees based on 16S rRNA gene sequences showed that strain XCD-X85(T) was associated with the genus Pseudomonas, and showed highest 16S rRNA gene sequence similarities to Pseudomonas pelagia CL-AP6(T) (99.0%) and Pseudomonas bauzanensis BZ93(T) (96.8%). DNA-DNA relatedness of strain XCD-X85T to P. pelagia JCM 15562(T) was 19 ± 1%. On the basis of the data presented above, it is concluded that strain XCD-X85(T) represents a novel species of the genus Pseudomonas, for which the name Pseudomonas salina sp. nov. is proposed. The type strain is XCD-X85(T) ( = CGMCC 1.12482(T) = JCM 19469(T)).

A Gram-negative, short rod-shaped bacterial strain, YC06271T, was isolated from the vermicompost (VC) collected at Masan, Korea and its taxonomic position was investigated by a polyphasic taxonomic approach. Strain YC06271T grew optimally at 28-30 degrees C and at pH 7.0-9.0. The 16S rRNA gene sequence of strain YC06271T was most closely related to members of the genera Bordetella (96.4-95.8 %), Achromobacter (96.0-95.7 %), Alcaligenes (96.0-94.2 %), Pusillimonas noertemannii (95.9 %), Pigmentiphaga (95.8-95.5 %) and less than 95.5 % similarity with the members of the other genera of the family Alcaligenaceae. Strain YC06271T contained ubiquinone-8 (Q-8) as the major respiratory quinone system and putrescine as the major polyamine. The major fatty acids of strain YC06271T were C16:1omega7c and/or C15:0 iso 2-OH and C16:0. The major polar lipids were phosphatidylglycerol and phosphatidylethanolamine. The G+C content of the genomic DNA was 55.4 mol%. Phylogenetic analysis, biochemical, chemotaxonomic and phenotypic characteristics strongly supported the differentiation of strain YC06271T from the validly published genera of the family Alcaligenaceae. Therefore, it is proposed that strain YC06271T represents a novel species within a novel genus, with the name Eiseniicola composti gen. nov., sp. nov. The type strain is YC06271T (= KCTC 22250T = DSM 21045T).

Sampling of seafood and dairy processing facilities in the north-eastern USA produced 18 isolates of Listeria spp. that could not be identified at the species-level using traditional phenotypic and genotypic identification methods. Results of phenotypic and genotypic analyses suggested that the isolates represent two novel species with an average nucleotide blast identity of less than 92% with previously described species of the genus Listeria. Phylogenetic analyses based on whole genome sequences, 16S rRNA gene and sigB gene sequences confirmed that the isolates represented by type strain FSL M6-0635(T) and FSL A5-0209 cluster phylogenetically with Listeria cornellensis. Phylogenetic analyses also showed that the isolates represented by type strain FSL A5-0281(T) cluster phylogenetically with Listeria riparia. The name Listeria booriae sp. nov. is proposed for the species represented by type strain FSL A5-0281(T) ( =DSM 28860(T) =LMG 28311(T)), and the name Listeria newyorkensis sp. nov. is proposed for the species represented by type strain FSL M6-0635(T) ( =DSM 28861(T) =LMG 28310(T)). Phenotypic and genotypic analyses suggest that neither species is pathogenic. © 2015 IUMS.

Two novel thiosulfate-oxidizing strains were isolated from sediment of the littoral zone of a freshwater lake (Lake Chiemsee, Bavaria, Germany). The new isolates, designated CS-K1 and CS-K2T, were gram-negative, slightly curved rods with pointed ends that were motile by means of single polar flagella. Both strains were obligately aerobic and grew on a variety of organic substrates, but not autotrophically. The utilization of thiosulfate led to an increase in the growth yield, indicating that these strains were able to grow chemolithoheterotrophically by oxidation of thiosulfate to sulfate. The optimum thiosulfate concentrations for growth were determined to be 10 mM for strain CS-K1 and 20 mM for strain CS-K2T. Phylogenetically, both strains were affiliated to the beta-Proteobacteria. Their characterization by a polyphasic approach resulted in the placement of both strains into a single species that is related only distantly to any known type species. Thus, the creation of a novel taxon is proposed, with the name Limnobacter thiooxidans gen. nov., sp. nov., to include the novel strains. In addition, the phylogenetic position of the chemolithoheterotrophic strain 'Thiobacillus' Q was determined.

An endophytic actinobacterium, strain WES2 T , was isolated from the stem of a jasmine rice plant collected from a paddy field in Thung Gura Rong Hai, Roi Et province, Thailand. As a result of a polyphasic study, this strain was identified as representing a novel member of the genus Streptomyces. This strain was a Gram-stain-positive, aerobic actinobacterium with well-developed substrate mycelia and forming chains of looped spores. The closest phylogenetic relations, which shared the highest 16S rRNA gene sequence similarity, were Streptomyces nogalater JCM 4799 T and Streptomyces lavenduligriseus NRRL-ISP 5487 T at 99.1 and 99.0 %, respectively. Chemotaxonomic data, including major fatty acids, cell wall components and major menaquinones, confirmed the affiliation of WES2 T to the genus Streptomyces. The data from the phylogenetic analysis, including physiological and biochemical studies and DNA-DNA hybridization, revealed the genotypic and phenotypic differentiation of WES2 T from the most closely related species with validly published names. The name proposed for the novel species is Streptomycesroietensis sp. nov. The type strain is WES2 T (=DSM 101729=NRRL B-65344).

pharmacokinetics parameters, biodistribution, T/NT radios were collected and calculated during and after the imaging. Moreover, the whole body image, heart planer scintigraphy and tomography were investigated on pharmacodynamics. The same procedure were performed to 99m Tc-MIBI. Results:Blood-pool clearance of 99m Tc-CO-MIBI was modeled and found to be biexponential during 2 hours after injection. The pharmacokinetics conform to two-compartment with 436.36±54.77 ml/h of blood clearance (CL) and half lives T α(1/2 ))=l.46±0.13 min for the fast early clearance, T β(1/2) =97.3+20.51 min for the slow late clearance. The clearance kinetics were faster than 99m Tc-MIBI which of CL=25 8.76±27.88 ml/h, T α(1/2) =2.21±0.09 min, T β(1/2) =163±14.1 min, respectively. The time-radioactivity curves showed that the pulmonary uptake curves were the lowest, the hepatic uptake curves were above the hearts early but descending so quickly as to start bellowing the heart curves at about 40min which were significant difference of 99m Tc-MIBI. To the latter, the liver curves were above the myocardial uptake curves sustained over 2 hours period post injection. The heart uptake ID% of 99m Tc-CO-MIBI were more than that of 99m Tc-MIBI at 10, 30, 60, 90, 120 min. The heart-lung and heart-liver ratios were also significantly different. For 99m Tc-CO-MIBI, they were 3.18±0.08 and 1.05±0.05 by 40 min while 99m Tc-MIBI 2.87±0.11 and 0.70±0.05, respectively. The planar and SPECT imaging of excellent quality during 10 to 120 min demonstrated that 99m Tc-CO-MIBI was high absorbed initially by myocardium and quickly clearance from liver. The whole body image show that the radioactivity mostly removed to the gallbladder and the intestines either. We can obtain perfect myocardial image without liver activity disturbance in condition of no extra fatty diets Conclusions: The result of this study suggested that the single alkaline component 99m Tc-CO-MIBI solution had better pharmacokinetics properties and

Development of 99Mo/99mTc Generator System for Production of Medical Radionuclide 99mTc using a Neutron-activated 99Mo and Zirconium Based Material (ZBM as its Adsorbent

Full Text Available Molybdenum produced from fission of U-235 is the most desirable precursor for 99Mo/99mTc generator system as it is non-carrier added and has high specific activity. However, in the last decade there has been short supply of 99Mo due to several constrains. Therefore, there have been many works performed for development of 99Mo/99mTc generator system using 99Mo which is not produced from either LEU or HEU. This report deals with development of 99Mo/99mTc generator system where zirconium-based material (ZBM is used as adsorbent of neutron-activated 99Mo. The system was prepared by firstly irradiating natural Mo in the G. A. Siwabessy reactor to produce neutron-activated 99Mo. The target was dissolved in NaOH 4N and then neutralized with 12 M HCl. The 99Mo solution was then mixed with a certain amount of ZBM followed by heating at 90°C for three hours to allow the 99Mo adsorbed on ZBM. The 99Mo-ZBM (9.36 GBq of 99Mo was Mo/ 4.2 g ZBM was packed on a fritz-glass column. This column was then fitted serially with an alumina column for trapping 99Mo breakthrough. The columns were then eluted daily with saline solution for up to one week. The yield of 99mTc was found to be between 53.7 – 74% (n= 5. All 99mTc eluates were clear solutions with pH of 5. Breakthrough of 99Mo in 99mTc eluates was found to be 0.031 ± 0.019 μCi 99Mo/ mCi 99mTc (n= 5 which was less than the maximum activity of 99Mo allowed in 99mTc solution ( 99%. Radiolabeling of this 99mTc towards methylene diphosphonate (MDP kit gave a radiolabelling efficiency of 99%. In summary, a new 99Mo/99mTc generator system that used neutron-activated 99Mo and ZBM as its adsorbent has been successfully prepared. The 99mTc produced from this new 99Mo/99mTc generator system attained the quality of 99mTc required for medical purposes.

A complex running system, such as the NOvA online data acquisition, consists of a large number of distributed but closely interacting components. This paper describes a generic real-time correlation analysis and event identification engine, named Message Analyzer. Its purpose is to capture run time abnormalities and recognize system failures based on log messages from participating components. The initial design of analysis engine is driven by the data acquisition (DAQ) of the NOvA experiment. The Message Analyzer performs filtering and pattern recognition on the log messages and reacts to system failures identified by associated triggering rules. The tool helps the system maintain a healthy running state and to minimize data corruption. This paper also describes a domain specific language that allows the recognition patterns and correlation rules to be specified in a clear and flexible way. In addition, the engine provides a plugin mechanism for users to implement specialized patterns or rules in generic languages such as C++.

Five Gram-negative bacterial strains, oxidase-positive, motile by means of more than one polar flagella, facultative anaerobe, arginine dihydrolase-negative, lysine- and omithine decarboxylase-positive, sensitive to the vibriostatic agent O/129, were isolated from a flow-through rotifer culture system in Gent, Belgium, and previously characterized by fluorescent amplified fragment length polymorphism. Comparison of the 16S rDNA sequence of strain LMG 21460T indicated close relationships (approximately 99% similarity) to Vibrio campbellii, Vibrio harveyi, Vibrio alginolyticus and Vibrio parahaemolyticus. However, DNA hybridization experiments revealed similarity values below 70% with its closest species V. campbellii and V. harveyi. Additionally, the analysed strains differ from related Vibrio species by the utilization of melibiose and production of acid from L-arabinose and amygdalin. Among the strains analysed, differences were observed in some phenotypic characters, particularly susceptibility to ampicillin, polymyxin B and amikacin, and urease activity. The major fatty acids identified were 16:0, 18:1 omega7c, 14:0, 12:0 3-OH and 18:0. Vibrio rotiferianus sp. nov. is proposed, with type strain LMG 21460T (=CAIM 577T); it has a DNA G+C content of 44.5 +/- 0.01 mol%.

Strains KFC-22(T) and SPC-20(T) are yellow-pigmented, Gram-positive, aerobic, non-motile, rod-shaped bacteria that were isolated from a soil sample near the Kafni glacier in the Himalayan mountain ranges in India, and from a spade core sediment sample from the Antarctic Ocean at Larsemann Hill, respectively. In both cases, the cell-wall peptidoglycan contained 2,4-diaminobutyric acid as the diamino acid, anteiso-C(15 : 0), anteiso-C(17 : 0) and iso-C(16 : 0) were the predominant fatty acids and MK-11 was the major isoprenoid quinone in the cell membrane. On the basis of the above-mentioned characteristics, both strains can be assigned to the genus Leifsonia. The strains share 16S rRNA gene sequence similarity of 97.7 % and DNA relatedness of only 10 %, indicating that they represent different species. A blast analysis indicated that Leifsonia pindariensis PON10(T) was the closest phylogenetic neighbour of strains SPC-20(T) and KFC-22(T), showing 16S rRNA gene sequence similarities of 97.3 and 97.7 %, respectively. However, at the whole-genome level, strains KFC-22(T) and SPC-20(T) shared 42 and 11 % DNA-DNA relatedness, respectively, with L. pindariensis PON10(T). In addition, both strains exhibited several phenotypic differences with respect to L. pindariensis PON10(T). Thus, on the basis of the differences that the two strains exhibited with respect to L. pindariensis, both were identified as representing novel species of the genus Leifsonia, for which the names Leifsonia kafniensis sp. nov. (type strain KFC-22(T) =NCCB 100216(T) =LMG 24362(T)) and Leifsonia antarctica sp. nov. (type strain SPC-20(T) =NCCB 100227(T) =LMG 24541(T)) are proposed.

The new 99mTc myocardial perfusion imaging agents: 99mTc-sestamibi and 99mTc-teboroxime

Berman, D.S.; Kiat, H.; Maddahi, J.

1991-01-01

The two new 99m (99mTc) labeled myocardial perfusion agents, 99mTc-Sestamibi and 99mTc-Teboroxime, are now available for routine clinical application. Both agents allow assessment of ejection fraction by the first-pass technique at rest or during exercise, thus providing additional information not available with thallium-201. 99mTc-Sestamibi has long myocardial residence time, as well as adequate myocardial extraction, providing images of higher count density and superior quality compared with thallium-201. 99mTc-Teboroxime has excellent myocardial uptake characteristics but is cleared very rapidly from the myocardium. Both tracers have shown results similar to those obtained with thallium-201 for detection of coronary artery disease and the assessment of defect reversibility. 99mTc-Sestamibi studies using the rest/stress imaging sequence can be accomplished in approximately 5 hours; studies using dual-isotope imaging (rest thallium-201 and stress 99mTc-Sestamibi injection) can be completed in 1 to 2 hours. Gated stress images can be performed with 99mTc-Sestamibi, providing simultaneous information of myocardial perfusion at stress and resting wall motion or thickening and allowing rapid differentiation of ischemic from infarcted tissue. Because of its slow myocardial clearance and absence of redistribution, 99mTc-Sestamibi allows uncoupling of the time of injection from the time of imaging and thus can be valuable in the evaluation of acute myocardial infarction and outcome of thrombolytic therapy. With 99mTc-Teboroxime, rapid serial studies are feasible. Pharmacologic stress and rest studies with 99mTc-Teboroxime single photon emission computed tomography potentially can be completed in under 30 minutes. 73 references

Deep Convolutional Networks for Event Reconstruction and Particle Tagging on NOvA and DUNE

CERN Multimedia

CERN. Geneva

2017-01-01

Deep Convolutional Neural Networks (CNNs) have been widely applied in computer vision to solve complex problems in image recognition and analysis. In recent years many efforts have emerged to extend the use of this technology to HEP applications, including the Convolutional Visual Network (CVN), our implementation for identification of neutrino events. In this presentation I will describe the core concepts of CNNs, the details of our particular implementation in the Caffe framework and our application to identify NOvA events. NOvA is a long baseline neutrino experiment whose main goal is the measurement of neutrino oscillations. This relies on the accurate identification and reconstruction of the neutrino flavor in the interactions we observe. In 2016 the NOvA experiment released results for the observation of oscillations in the ν μ → ν e channel, the first HEP result employing CNNs. I will also discuss our approach at event identification on NOvA as well as recent developments in the application of CNN...

Multi-Center Traffic Management Advisor Operational Field Test Results

Farley, Todd; Landry, Steven J.; Hoang, Ty; Nickelson, Monicarol; Levin, Kerry M.; Rowe, Dennis W.

2005-01-01

The Multi-Center Traffic Management Advisor (McTMA) is a research prototype system which seeks to bring time-based metering into the mainstream of air traffic control (ATC) operations. Time-based metering is an efficient alternative to traditional air traffic management techniques such as distance-based spacing (miles-in-trail spacing) and managed arrival reservoirs (airborne holding). While time-based metering has demonstrated significant benefit in terms of arrival throughput and arrival delay, its use to date has been limited to arrival operations at just nine airports nationally. Wide-scale adoption of time-based metering has been hampered, in part, by the limited scalability of metering automation. In order to realize the full spectrum of efficiency benefits possible with time-based metering, a much more modular, scalable time-based metering capability is required. With its distributed metering architecture, multi-center TMA offers such a capability.

Lab notebooks as scientific communication: Investigating development from undergraduate courses to graduate research

Directory of Open Access Journals (Sweden)

Jacob T. Stanley

2016-09-01

Full Text Available In experimental physics, lab notebooks play an essential role in the research process. For all of the ubiquity of lab notebooks, little formal attention has been paid to addressing what is considered “best practice” for scientific documentation and how researchers come to learn these practices in experimental physics. Using interviews with practicing researchers, namely, physics graduate students, we explore the different experiences researchers had in learning how to effectively use a notebook for scientific documentation. We find that very few of those interviewed thought that their undergraduate lab classes successfully taught them the benefit of maintaining a lab notebook. Most described training in lab notebook use as either ineffective or outright missing from their undergraduate lab course experience. Furthermore, a large majority of those interviewed explained that they did not receive any formal training in maintaining a lab notebook during their graduate school experience and received little to no feedback from their advisors on these records. Many of the interviewees describe learning the purpose of, and how to maintain, these kinds of lab records only after having a period of trial and error, having already started doing research in their graduate program. Despite the central role of scientific documentation in the research enterprise, these physics graduate students did not gain skills in documentation through formal instruction, but rather through informal hands-on practice.

The neuropeptide oxytocin may increase social cohesion by making us more willing to trust others and/or to conform to their opinions. Here we investigated whether intranasal oxytocin can influence acceptance of advice given on solving everyday social problems by either individual expert (psychologist) or non-expert advisors with or without influencing their perceived likeability or trustworthiness. In a double-blind, between-subject, placebo-control design study in 160 male and female subjects, intranasal oxytocin (24IU) only significantly enhanced acceptance of advice given by female psychologists who were rated as the most trustworthy advisors. However, oxytocin itself did not alter either trustworthiness or likeability ratings. The oxytocin effect on acceptance of the female psychologist's advice was not maintained after a week, with subjects mainly reverting to their original solutions. These findings suggest that while oxytocin can transiently increase acceptance of advice from the most trustworthy individuals this is because it makes subjects more likely to conform to their opinions rather than enhancing their perceived trustworthiness or likeability. Thus in every day contexts oxytocin may primarily promote social cohesion by facilitating conformity towards the opinions of the most trusted individuals. Copyright © 2017.

Installation and evaluation of a nuclear power plant Operator Advisor based on artificial intelligence technology

International Nuclear Information System (INIS)

Hajek, B.K.; Miller, D.W.

1993-02-01

The Artificial Intelligence Group in the Nuclear Engineering Program has designed and built an Operator Advisor (OA), an AI system to monitor nuclear power plant parameters, detect component and system malfunctions, dispose their causes, and provide the plant operators with the correct procedures for mitigating the consequences of the malfunctions. It then monitors performance of the procedures, and provides backup steps when specific operator actions fail. The OA has been implemented on Sun 4 workstations in Common Lisp, and has been interfaced to run in real time on the Perry Nuclear Power Plant full-function simulator in the plant training department. The eventual goal for a fully functioning Operator Advisor would be to have reactor operators receive direction for all plant operations. Such a goal requires considerable testing of the system within limited malfunction boundaries, an extensive Verification ampersand Validation (V ampersand V) effort, a large knowledge base development effort, and development of tools as part of the system to automate its maintenance. Clearly, these efforts are beyond the scope of the feasibility effort expended during this project period. However, as a result of this project, we have an AI based platform upon which a complete system can be built

A modified {sup 99} Mo - {sup 99} Tc gel generator is described. The new generator is based on the use of zirconium molybdophosphate - {sup 99} Mo gel in which {sup 99} Mo chemically combined in the gel structure, where {sup 99m}Tc can be easily eluted with distilled water or saline. The gel was prepared via chemical reaction between zirconyl chloride and molybdophosphate - {sup 99} Mo solution. The PH of the reaction mixture was adjusted with NaOH. Different gels have been prepared by varying the molar ratio of Mo:Zr:p. The PH and time of digeston on complete gel formation was also investigated in order to optimize the condition of gel preparation. Molybdophosphate {sup 32} P solution was used to determine the phosphorous content in the gel and in the {sup 99m}Tc eluate. The temperature and time of drying of the gel and their effect on {sup 99m}Tc elution efficiency were also studied. From the data obtained, the optimum conditions for routine production of {sup 99} Mo - {sup 99m}Tc generator are presented and discussed. 2 figs., 6 tabs.

Strain S3-2 T is a facultative anaerobe that lacks the ability to produce violacein but shows antibiotic resistance, psychrotolerance, incomplete denitrification, and fermentation. The draft genome of strain S3-2 T has a size of ~5.8 Mbp and contains 5,297 genes, including 115 RNA genes. Based on the phenotypic properties of the strain, the low in silico DNA-DNA hybridization (DDH) values with related genomes (<35%), and the low whole genome-based average nucleotide identity (ANI) (<86%) with other strains within the genus Janthinobacterium, we propose that strain S3-2 T is the type strain (= DSM 102223 = LMG 29653) of a new species within this genus. We propose the name Janthinobacterium psychrotolerans sp. nov. to emphasize the capability of the strain to grow at low temperatures.

A Gram-positive, rod-shaped, non-spore-forming bacterium (strain K362(T)) was isolated from a deep-water marine sponge collected off the coast of Curaçao in the Netherlands Antilles. On the basis of 16S rRNA gene sequence similarities, strain K362(T) was shown to belong to the genus Tsukamurella, being most closely related to Tsukamurella pulmonis (99.2 %), Tsukamurella tyrosinosolvens (98.9 %), Tsukamurella strandjordii (98.8 %), Tsukamurella pseudospumae (98.8 %) and Tsukamurella spumae (98.8 %). A combination of the substrate utilization patterns, the fatty acid and mycolic acid profiles and the DNA-DNA hybridization results supported the affiliation of strain K362(T) to the genus Tsukamurella and enabled the genotypic and phenotypic differentiation of strain K362(T) from the seven recognized Tsukamurella species. Strain K362(T) therefore represents a novel species of the genus Tsukamurella, for which the name Tsukamurella spongiae sp. nov. is proposed. The type strain is K362(T) (=DSM 44990(T)=NRRL B-24467(T)).

This manuscript describes the development of PTT (Partial Thromboplastin Time) Advisor, one of the first of a handful of iOS-based mobile applications to be released by the US Centers for Disease Control and Prevention (CDC). PTT Advisor has been a collaboration between two groups at CDC (Informatics R&D and Laboratory Science), and one partner team (Clinical Laboratory Integration into Healthcare Collaborative - CLIHC). The application offers clinicians a resource to quickly select the appropriate follow-up tests to evaluate patients with a prolonged PTT and a normal Prothrombin Time (PT) laboratory result. The application was designed leveraging an agile methodology, and best practices in user experience (UX) design and mobile application development. As it is an open-source project, the code to PTT Advisor was made available to the public under the Apache Software License. On July 6, 2012, the free app was approved by Apple, and was published to their App Store. Regardless of the complexity of the mobile application, the level of effort required in the development process should not be underestimated. There are several issues that make designing the UI for a mobile phone challenging (not just small screen size): the touchscreen, users' mobile mindset (tasks need to be quick and focused), and the fact that mobile UI conventions/expectations are still being defined and refined (due to the maturity level of the field of mobile application development).

Problems in clinical practice of domestic supply of 99Mo/99mTc. Considerations on the domestic production of 99Mo/99mTc

International Nuclear Information System (INIS)

Yamabayashi, Hisamichi

2012-01-01

At present, a bulky import product, 99 Mo supplied in Japan is produced by a nuclear fission method which enables to produce a generator system with no need of commercially preparing 99m Tc-labeled radiopharmaceuticals due to its high specific activity. However its usage of enriched uranium target leads to avoiding the fission method from the option of domestic production. In order to secure the domestic supply of 99 Mo/ 99m Tc, the neutron activation method, aiming to meet about 20% of domestic demand, is under development along with the re-start program of JMTR. Development of various production methods using accelerators are also in progress. In those non-fission methods with reactors or accelerators, rapid and effective procedures for concentration and refinement of 99m Tc solution eluted from 99 Mo of low specific activity are the subjects to be considered for attaining the stable labeling performances.

Rodriguez, Russell J.; Connell, L.; Redman, R.; Barrett, A.; Iszard, M.; Fonseca, A.

2010-01-01

During a survey of the culturable soil fungal population in samples collected in Taylor Valley, South Victoria Land, Antarctica, 13 basidiomycetous yeast strains with orange-coloured colonies were isolated. Phylogenetic analyses of internal transcribed spacer (ITS) and partial LSU rRNA gene sequences showed that the strains belong to the Dioszegia clade of the Tremellales (Tremellomycetes, Agaricomycotina), but did not correspond to any of the hitherto recognized species. Two novel species, Dioszegia antarctica sp. nov. (type strain ANT-03-116T =CBS 10920T =PYCC 5970T) and Dioszegia cryoxerica sp. nov. (type strain ANT-03-071T =CBS 10919T =PYCC 5967T), are described to accommodate ten and three of these strains, respectively. Analysis of ITS sequences demonstrated intrastrain sequence heterogeneity in D. cryoxerica. The latter species is also notable for producing true hyphae with clamp connections and haustoria. However, no sexual structures were observed. The two novel species can be considered obligate psychrophiles, since they failed to grow above 20 °C and grew best between 10 and 15 °C.

'Cand. Actinochlamydia clariae' gen. nov., sp. nov., a unique intracellular bacterium causing epitheliocystis in catfish (Clarias gariepinus in Uganda.

Directory of Open Access Journals (Sweden)

Andreas Steigen

Full Text Available BACKGROUND AND OBJECTIVES: Epitheliocystis, caused by bacteria infecting gill epithelial cells in fish, is common among a large range of fish species in both fresh- and seawater. The aquaculture industry considers epitheliocystis an important problem. It affects the welfare of the fish and the resulting gill disease may lead to mortalities. In a culture facility in Kampala, Uganda, juveniles of the African sharptooth catfish (Clarias gariepinus was observed swimming in the surface, sometimes belly up, showing signs of respiratory problems. Histological examination of gill tissues from this fish revealed large amounts of epitheliocysts, and also presence of a few Ichthyobodo sp. and Trichodina sp. METHODS AND RESULTS: Sequencing of the epitheliocystis bacterium 16S rRNA gene shows 86.3% similarity with Candidatus Piscichlamydia salmonis causing epitheliocystis in Atlantic salmon (Salmo salar. Transmission electron microscopy showed that the morphology of the developmental stages of the bacterium is similar to that of members of the family Chlamydiaceae. The similarity of the bacterium rRNA gene sequences compared with other chlamydia-like bacteria ranged between 80.5% and 86.3%. Inclusions containing this new bacterium have tubules/channels (termed actinae that are radiating from the inclusion membrane and opening on the cell surface or in neighbouring cells. CONCLUSIONS: Radiation of tubules/channels (actinae from the inclusion membrane has never been described in any of the other members of Chlamydiales. It seems to be a completely new character and an apomorphy. We propose the name Candidatus Actinochlamydia clariae gen. nov., sp. nov. (Actinochlamydiaceae fam. nov., order Chlamydiales, phylum Chlamydiae for this new agent causing epitheliocystis in African sharptooth catfish.

A filamentous, soil-dwelling cyanobacterial strain (9C-PST) was isolated from Mandsaur, Madhya Pradesh, India, and is described as a new species of the genus Nostoc. Extensive morphological and molecular characterization along with a thorough assessment of ecology was performed. The style of filament orientation, type and nature of the sheath (e.g. distribution and visibility across the trichome), and vegetative and heterocyte cell dimensions and shape were assessed for over one year using both the laboratory grown culture and the naturally occurring samples. Sequencing of the 16S rRNA gene showed 94 % similarity with Nostocpiscinale CENA21 while analyses of the secondary structures of the 16S-23S ITS region showed unique folding patterns that differentiated this strain from other species of Nostoc. The level of rbcl and rpoC1 gene sequence similarity was 91 and 94 % to Nostocsp. PCC 7524 and Nostocpiscinale CENA21, respectively, while the nifD gene sequence similarity was found to be 99 % with Nostocpiscinale CENA21. The phenotypic, ecological, genetic and phylogenetic observations indicate that the strain 9C-PST represents a novel species of the genus Nostoc with the name proposed being Nostoc thermotolerans sp. nov. according to the International Code of Nomenclature for Algae, Fungi, and Plants.

The phylogenetic classification of the species Burkholderia andropogonis within the Burkholderia genus was reassessed using 16S rRNA gene phylogenetic analysis and multilocus sequence analysis (MLSA). Both phylogenetic trees revealed two main groups, named A and B, strongly supported by high bootstrap values (100%). Group A encompassed all of the Burkholderia species complex, whi.le Group B only comprised B. andropogonis species, with low percentage similarities with other species of the genus, from 92 to 95% for 16S rRNA gene sequences and 83% for conserved gene sequences. Average nucleotide identity (ANI), tetranucleotide signature frequency, and percentage of conserved proteins POCP analyses were also carried out, and in the three analyses B. andropogonis showed lower values when compared to the other Burkholderia species complex, near 71% for ANI, from 0.484 to 0.724 for tetranucleotide signature frequency, and around 50% for POCP, reinforcing the distance observed in the phylogenetic analyses. Our findings provide an important insight into the taxonomy of B. andropogonis. It is clear from the results that this bacterial species exhibits genotypic differences and represents a new genus described herein as Robbsia andropogonis gen. nov., comb. nov.

It has been proposed to split the genus Burkholderia into two genera according to phylogenetic clustering: (1) a genus retaining this name and consisting mainly of animal and plant pathogens and (2) the genus Paraburkholderia including so-called environmental bacteria. The latter genus name has been validly published recently. During the period between the effective and valid publications of the genus name Paraburkholderia, 16 novel species of the genus Burkholderiawere described, but only two of them can be classified as members of this genus based on the emended genus description. Analysis of traits and phylogenetic positions of the other 11 species shows that they belong to the genus Paraburkholderia, and we propose to transfer them to this genus. The reclassified species names are proposed as Paraburkholderia dipogonis comb. nov., Paraburkholderia ginsengiterrae comb. nov., Paraburkholderia humisilvae comb. nov., Paraburkholderia insulsa comb. nov., Paraburkholderia kirstenboschensis comb. nov., Paraburkholderia metalliresistens comb. nov., Paraburkholderia monticola comb. nov., Paraburkholderia panaciterrae comb. nov., Paraburkholderia rhizosphaerae comb. nov., Paraburkholderia solisilvae comb. nov. and Paraburkholderia susongensis comb. nov. The remaining three species are transferred to the new genus Caballeronia gen. nov. proposed to accommodate twelve species of the genera Burkholderia and Paraburkholderia forming a distinctive clade in phylogenetic trees. The new genus members are Caballeronia choica comb. nov., Caballeronia cordobensis comb. nov., Caballeronia glathei comb. nov., Caballeronia grimmiae comb. nov., Caballeronia humi comb. nov., Caballeronia megalochromosomata comb. nov., Caballeronia jiangsuensis comb. nov., Caballeronia sordidicola comb. nov., Caballeronia telluris comb. nov., Caballeronia terrestris comb. nov., Caballeronia udeis comb. nov., and Caballeronia zhejiangensis comb. nov.

Liposomes labelled with gamma e miters like 99mTc, can be used for scintigraphic imaging to non-invasively track and quantify the distribution of liposomes in the body. In vitro studies were done to choose a suitable radiopharmaceutical (RF) to be attached to performed liposomes. 99mTc-Complexes (DTPA, ECD, MDP, MIBI) were used to label collagen liposomes. Commercial kits were labelled with 99mTc04-(TechnoNuclear). Quality controls of the RF were performed. Collagen liposomes suspended in saline 0.9% were incubated at 4.25.37 and 60 for 30 min. Efficiency of the labelling procedure was determined by gel filtration using Sephadex G25 (Pharmacia) and NaC10.9%. Samples of 100mL (74MBq), were seeded and fractions of 0.5mL were colleted and measured in an ionisation chamber (Capintec CRC). Stability of the labelled liposomes was assessed incubating 0.5mL, of the suspension with 1mL of human serum during 30 min at 37 . Dialysis was performed using dialysis bags of 64 K pore size and NaCI 0.9% at room temperature. Samples of the saline bath were collected at 30.60 and 90 min. and measured in a solid scintillation counter Ortec.Liposomes labelled with 99mTc-DTPA and 99mTcMIBI showed a labelling efficiency of 80%; liposomes incubated with 99mTc-MDP were labelled in a 50% and 99mTc-ECD did not bind to liposomes in the conditions of study. Incubation of labelled liposomes with human serum showed 50% of strong binding to the plasmatic proteins for 99mTc-DTPA but low values (5%) for the other specimens. Labelled liposomes were achieved, with different RF, showing a suitable in vitro stability to perform in vivo studies

This study describes a novel ericoid mycorrhizal fungus (ErMF), Gamarada debralockiae Midgley and Tran-Dinh gen. nov. sp. nov. Additionally, catabolism was explored from a genomic perspective. The nuclear and mitochondrial genomes of G. debralockiae were sequenced. Morphological characteristics were assessed on various media. Catabolic genes of G. debralockiae were explored using SignalP and dbCAN. Phylogenetic comparisons were undertaken using Phylogeny.fr. The 58.5-Mbp draft genome of G. debralockiae contained 17,075 putative genes. The complete mitochondrial genome was 28,168 bp in length. In culture, G. debralockiae produces slow-growing non-sporulating colonies. Gamarada debralockiae has many putative secreted catabolic enzymes. Phylogeny indicated G. debralockiae was distinct from known ascomycetous ErMF: Pezoloma ericae, Meliniomyces spp., Oidiodendron spp., and Cairneyella variabilis. It is closely related to many undescribed plant root-associated fungi and its nearest described relative is Hyphodiscus brevicollaris. Gamarada debralockiae has been recovered from virtually all Australian ericoid mycorrhizal studies and biogeographic data suggests the taxon is widespread in Australia. Gamarada debralockiae has similar catabolic potential to C. variabilis and co-occurs with C. variabilis at Australian sites. Plants that host multiple ErMF may benefit from subtle differences in catabolism that improve access to nitrogen and phosphorus from within recalcitrant organic matter.

Eight strains of Gram-negative, aerobic, asporogenous, neutrophilic, mesophilic, facultatively methylotrophic bacteria are taxonomically described. These icl- serine pathway methylobacteria utilize dichloromethane, methanol and methylamine as well as a variety of polycarbon compounds as the carbon and energy source. The major cellular fatty acids of the non-pigmented strains DM1, DM3, and DM5 to DM9 are C18:1, C16:0, C18:0, Ccy19:0 and that of the pink-pigmented strain DM4 is C18:1. The main quinone of all the strains is Q-10. The non-pigmented strains have similar phenotypic properties and a high level of DNA-DNA relatedness (81-98%) as determined by hybridization. All strains belong to the alpha-subgroup of the alpha-Proteobacteria. 16S rDNA sequence analysis led to the classification of these dichloromethane-utilizers in the genus Methylopila as a new species - Methylopila helvetica sp.nov. with the type strain DM9 (=VKM B-2189). The pink-pigmented strain DM4 belongs to the genus Methylobacterium but differs from the known members of this genus by some phenotypic properties, DNA-DNA relatedness (14-57%) and 16S rDNA sequence. Strain DM4 is named Methylobacterium dichloromethanicum sp. nov. (VKM B-2191 = DSMZ 6343).

Four Gram-stain-positive, catalase-negative, coccoid-shaped organisms were isolated from elephant oral cavities. The isolates were tentatively identified as streptococcal species based on the results of biochemical tests. Comparative 16S rRNA gene sequencing studies confirmed the organisms to be members of the genus Streptococcus. Two isolates (NUM 6304(T) and NUM 6312) were related most closely to Streptococcus salivarius with 96.8 % and 93.1 % similarity based on the 16S rRNA gene and the RNA polymerase β subunit encoding gene (rpoB), respectively, and to Streptococcus vestibularis with 83.7 % similarity based on the 60 kDa heat-shock protein gene (groEL). The other two isolates (NUM 6306(T) and NUM 6318) were related most closely to S. vestibularis with 97.0 % and 82.9 % similarity based on the 16S rRNA and groEL genes, respectively, and to S. salivarius with 93.5 % similarity based on the rpoB gene. Based on phylogenetic and phenotypic evidence, these isolates are suggested to represent novel species of the genus Streptococcus, for which the names Streptococcus loxodontisalivarius sp. nov. (type strain NUM 6304(T) = JCM 19287(T) = DSM 27382(T)) and Streptococcus saliviloxodontae sp. nov. (type strain NUM 6306(T) = JCM 19288(T) = DSM 27513(T)) are proposed. © 2014 IUMS.

The 99m Tc is used for diagnostic and therapy. It is produced starting from 99 Mo, absorbed in chromatographic columns, loaded with alumina that absorb only 0.2% of 99 Mo with high specific activities of 99 Mo, obtained from the 235 U fission. Given these conditions and limitations, new preparation procedures of 99 Mo/ 99m Tc generators, its have been developed, using zirconium molybdates gels that incorporates until 30% of 99 Mo, conserve similar characteristics of quality and purity that the traditional generator. The radiochemical characteristics of the 99m Tc elution, depend strongly on the gel preparation conditions. In particular, the present work has by object to determine the influence of the 99 Mo used type, fission or activation product, during the gels synthesis, as well as the used air flow for the agitation in the gels preparation and its influence in the 99 Mo/ 99m Tc generators quality. When diminishing the flow of agitation air the efficiency it increases and in the radionuclide purity of the eluates and when using 99 Mo from fission for the gels production it increases in an important way the elutriation efficiency, the radiochemical and radionuclide purity of the 99m Tc eluates.

Muon Neutrino Disappearance in NOvA with a Deep Convolutional Neural Network Classifier

Energy Technology Data Exchange (ETDEWEB)

Rocco, Dominick Rosario [Minnesota U.

2016-03-01

The NuMI Off-axis Neutrino Appearance Experiment (NOvA) is designed to study neutrino oscillation in the NuMI (Neutrinos at the Main Injector) beam. NOvA observes neutrino oscillation using two detectors separated by a baseline of 810 km; a 14 kt Far Detector in Ash River, MN and a functionally identical 0.3 kt Near Detector at Fermilab. The experiment aims to provide new measurements of Δm² and θ23 and has potential to determine the neutrino mass hierarchy as well as observe CP violation in the neutrino sector. Essential to these analyses is the classification of neutrino interaction events in NOvA detectors. Raw detector output from NOvA is interpretable as a pair of images which provide orthogonal views of particle interactions. A recent advance in the field of computer vision is the advent of convolutional neural networks, which have delivered top results in the latest image recognition contests. This work presents an approach novel to particle physics analysis in which a convolutional neural network is used for classification of particle interactions. The approach has been demonstrated to improve the signal efficiency and purity of the event selection, and thus physics sensitivity. Early NOvA data has been analyzed (2.74×10²⁰ POT, 14 kt equivalent) to provide new best- fit measurements of sin²(θ23) = 0.43 (with a statistically-degenerate compliment near 0.60) and |Δm2 | = 2.48 × 10^-3 eV².

The System Advisor Model (SAM) is a free software tool that performs detailed analysis of both system performance and system financing for a variety of renewable energy technologies. This report provides detailed validation of the SAM flat plate photovoltaic performance model by comparing SAM-modeled PV system generation data to actual measured production data for nine PV systems ranging from 75 kW to greater than 25 MW in size. The results show strong agreement between SAM predictions and field data, with annualized prediction error below 3% for all fixed tilt cases and below 8% for all one axis tracked cases. The analysis concludes that snow cover and system outages are the primary sources of disagreement, and other deviations resulting from seasonal biases in the irradiation models and one axis tracking issues are discussed in detail.

A light-pink-pigmented, microaerophilic bacterium was obtained from a methanotrophic consortium enriched from acidic Sphagnum peat and designated strain Pf56(T). Cells of this bacterium were Gram-negative, non-motile, thick curved rods that contained a vesicular intracytoplasmic membrane system characteristic of some purple non-sulfur alphaproteobacteria. The absorption spectrum of acetone/methanol extracts of cells grown in the light showed maxima at 363, 475, 505, 601 and 770 nm; the peaks at 363 and 770 nm are characteristic of bacteriochlorophyll a. However, in contrast to purple non-sulfur bacteria, strain Pf56(T) was unable to grow phototrophically under anoxic conditions in the light. Best growth occurred on some sugars and organic acids under micro-oxic conditions by means of fermentation. The fermentation products were propionate, acetate and hydrogen. Slow chemo-organotrophic growth was also observed under fully oxic conditions. Light stimulated growth. C1 substrates were not utilized. Strain Pf56(T) grew at pH 4.0-7.0 (optimum pH 5.5-6.5) and at 15-30 °C (optimum 22-28 °C). The major cellular fatty acids were 19 : 0 cyclo ω8c and 18 : 1ω7c; quinones were represented by ubiquinone Q-10. The G+C content of the DNA was 70.0 mol%. Strain Pf56 displays 93.6-94.7 and 92.7-93.7% 16S rRNA gene sequence similarity to members of the families Methylocystaceae and Beijerinckiaceae, respectively, and belongs to a large cluster of environmental sequences retrieved from various wetlands and forest soils in cultivation-independent studies. Phenotypic, genotypic and chemotaxonomic characteristics of strain Pf56(T) suggest that it represents a novel genus and species of bacteriochlorophyll a-containing fermentative bacteria, for which the name Roseiarcus fermentans gen. nov., sp. nov. is proposed. Strain Pf56(T) ( = DSM 24875(T) = VKM B-2876(T)) is the type strain of Roseiarcus fermentans, and is also the first characterized member of a novel family

Tc-99m-HMPAO reflects tissue perfusion but Tc-99m-ECD uptake is affected by tissue viability in addition to tissue perfusion which the varied state of cellular retention of Tc-99m-ECD reflects. Luxuriously perfused area on Tc-99m-HMPAO SPECT implies that this cortex was already reperfused either spontaneously or after thrombolysis and that accompanied paralysis of vascular reactivity in those zones warms progressive deterioration. We tried to find out if we can use sequential Tc-99m-ECD/Tc-99m-HMPAO SPECT to reveal cortical perfusion and severity and range of risky areas of cerbral cortex despite reperfusion in sub-acute infarction. In 13 patients (M ; F =7 : 6, mean age 57 (range: 26-84)) with cortical (n=12) and basal ganglia infarction (1), we performed sequential Tc-99m-ECD/Tc-99m-HMPAO SPECT at the same position. At first, 555 MBq of Tc-99m-ECD was injected and imaged and then 1110 MBq of Tc-99m-HMPAO was injected again and imaged with the patients in situ, and the first image (Tc-99m-ECD) and the subtracted image (2nd- 1st : Tc-99m-HMPAO) were compared slice by slice. Study was done from 3 days to 31 days (16{+-}9) after ictus. Tc-99m-ECD uptake was always less than or equal to Tc-99m-HMPAO uptake at the lesion in all cases. Luxury perfusion was prominent in four patients. Mismatched uptake was found in 10 patients. Severity of mismatch showed diverse spectrum and was ranged from total middle cerebral artery territory (1 case) to peripheral thin zones around infarction (2 cases). The other 7 showed intermediate amount of tissues with mismatch , i.e., Tc-99m-ECD defects where Tc-99m-HMPAO uptake is in part increased, normal or decreased. Upon discharge, patients having more uptake with Tc-99m-ECD predicted improvement. Patients having mismatched uptake went dichotomous way. In conclusion, Tc-99m-ECD/Tc-99m-HMPAO sequential SPECT is feasible and reveal both tissue perfusion (Tc-99m-HMPAO ) and discrepant Tc-99m-ECD uptake probably reflecting viability in acute

A Gram-negative, aerobic, non-spore-forming, motile and ovoid or rod-shaped bacterial strain, designated MA2-16(T), was isolated from ark shell (Scapharca broughtonii) collected from the South Sea, South Korea. Strain MA2-16(T) was found to grow optimally at 30°C, at pH 7.0-8.0 and in the presence of 2.0% (w/v) NaCl. Neighbour-joining, maximum-likelihood and maximum-parsimony phylogenetic trees based on 16S rRNA gene sequences revealed that strain MA2-16(T) clustered with the type strain of Sedimentitalea nanhaiensis. The novel strain exhibited a 16S rRNA gene sequence similarity value of 97.1% to the type strain of S. nanhaiensis. In the neighbour-joining phylogenetic tree based on gyrB sequences, strain MA2-16(T) formed an evolutionary lineage independent of those of other taxa. Strain MA2-16(T) contained Q-10 as the predominant ubiquinone and C18:1 ω7c and 11-methyl C18:1 ω7c as the major fatty acids. The major polar lipids of strain MA2-16(T) were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, an unidentified aminolipid and an unidentified lipid. The DNA G+C content of strain MA2-16(T) was 57.7 mol% and its DNA-DNA relatedness values with the type strains of S. nanhaiensis and some phylogenetically related species of the genera Leisingera and Phaeobacter were 13-24%. On the basis of the data presented, strain MA2-16(T) is considered to represent a novel genus and novel species within the family Rhodobacteraceae, for which the name Aliisedimentitalea scapharcae gen. nov., sp. nov. is proposed. The type strain is MA2-16(T) (=KCTC 42119(T) =CECT 8598(T)).

The purpose of this study was to examine the effects of amino acid, hydrocarbon, and polyethylene glycol (PEG) linkers on the melanoma targeting and imaging properties of (99m)Tc-labeled lactam bridge-cyclized HYNIC-linker-Nle-CycMSHhex (hydrazinonicotinamide-linker-Nle-c[Asp-His-DPhe-Arg-Trp-Lys]-CONH2) peptides. Four novel peptides (HYNIC-GGGNle-CycMSHhex, HYNIC-GSGNle-CycMSHhex, HYNIC-PEG2Nle-CycMSHhex, and HYNIC-AocNle-CycMSHhex) were designed and synthesized. The melanocortin-1 receptor binding affinities of the peptides were determined in B16/F1 melanoma cells. The biodistribution of (99m)Tc(ethylenediaminediacetic acid [EDDA])-HYNIC-GGGNle-CycMSHhex, (99m)Tc(EDDA)-HYNIC-GSGNle-CycMSHhex, (99m)Tc(EDDA)-HYNIC-PEG2Nle-CycMSHhex, and (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex were determined in B16/F1 melanoma-bearing C57 mice at 2 h after injection to select a lead peptide for further evaluation. The melanoma targeting and imaging properties of (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex were further examined because of its high melanoma uptake. The inhibitory concentrations of 50% (IC50) for HYNIC-GGGNle-CycMSHhex, HYNIC-GSGNle-CycMSHhex, HYNIC-PEG2Nle-CycMSHhex, and HYNIC-AocNle-CycMSHhex were 0.7 ± 0.1, 0.8 ± 0.09, 0.4 ± 0.08, and 0.3 ± 0.06 nM, respectively, in B16/F1 melanoma cells. Among these four (99m)Tc-labeled peptides, (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex displayed the highest melanoma uptake (22.3 ± 1.72 percentage injected dose/g) at 2 h after injection. (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex exhibited high tumor-to-normal-organ uptake ratios except for the kidneys. The tumor-to-kidney uptake ratios of (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex were 3.29, 3.63, and 6.78 at 2, 4, and 24 h, respectively, after injection. The melanoma lesions were clearly visualized by SPECT/CT using (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex as an imaging probe at 2 h after injection. High melanoma uptake and fast urinary clearance of (99m)Tc(EDDA)-HYNIC-AocNle-CycMSHhex highlighted its

A few members of the family Acetobacteraceae are cellulose-producers, while only six members fix nitrogen. Bacterial strain RG3T, isolated from Kombucha tea, displays both of these characteristics. A high bootstrap value in the 16S rRNA gene sequence-based phylogenetic analysis supported the position of this strain within the genus Gluconacetobacter, with Gluconacetobacter hansenii LMG 1527T as its nearest neighbour (99.1 % sequence similarity). It could utilize ethanol, fructose, arabinose, glycerol, sorbitol and mannitol, but not galactose or xylose, as sole sources of carbon. Single amino acids such as L-alanine, L-cysteine and L-threonine served as carbon and nitrogen sources for growth of strain RG3T. Strain RG3T produced cellulose in both nitrogen-free broth and enriched medium. The ubiquinone present was Q-10 and the DNA base composition was 55.8 mol% G+C. It exhibited low values of 5.2-27.77 % DNA-DNA relatedness to the type strains of related gluconacetobacters, which placed it within a separate taxon, for which the name Gluconacetobacter kombuchae sp. nov. is proposed, with the type strain RG3T (=LMG 23726T=MTCC 6913T).

Two agar-degrading halophilic archaeal strains, 62 E(T) and 197 A, were isolated from commercial salt samples. Cells were non-motile cocci, approximately 1.2-2.0 µm in diameter and stained Gram-negative. Colonies were pink-pigmented. Strain 62 E(T) was able to grow with 24-30% (w/v) NaCl (optimum, 27%), at pH 6.5-8.5 (optimum, pH 7.5) and at 22-47 °C (optimum, 42 °C). The 16S rRNA gene sequences of strains 62 E(T) and 197 A were identical, and the level of DNA-DNA relatedness between them was 90 and 90% (reciprocally). The closest relative was Halococcus saccharolyticus JCM 8878(T) with 99.7% similarity in 16S rRNA orthologous gene sequences, followed by Halococcus salifodinae JCM 9578(T) (99.6%), while similarities with other species of the genus Halococcus were equal to or lower than 95.1%. The rpoB' gene tree strongly supported that the two strains were members of the genus Halococcus . Mean DNA-DNA relatedness between strain 62 E(T) and H. saccharolyticus JCM 8878(T) and H. salifodinae JCM 9578(T) was 46 and 44%, respectively. The major polar lipids were archaeol derivatives of phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, derived from both C20C20 and C20C25 archaeol, and sulfated diglycosyl archaeol-1. Several unidentified glycolipids were present. Based on the phenotypic and phylogenetic analyses, the isolates are considered to represent a novel species of the genus Halococcus , for which the name Halococcus agarilyticus sp. nov. is proposed. The type strain is 62 E(T) ( = JCM 19592(T) =KCTC 4143(T)). © 2015 IUMS.

A novel extremely halophilic member of the Archaea, strain 40T, was isolated from Egypt (Aswan). This isolate requires at least 1.6 M sodium chloride for growth and exhibits optimal growth between 37 and 42 degrees C. Determination of the entire 16S rRNA gene sequence revealed the highest similarity to the type strain of Natrialba asiatica (> 99%). Polar lipid analysis indicated that strain 40T and Natrialba asiatica have essentially identical compositions, indicating that the former is a member of genus Natrialba. However, physiological and biochemical data provided evidence that Natrialba asiatica strains B1T and 172P1T, as well as strain 40T, are sufficiently different to be divided in three different species. The G+C content of strain 40T was 61.5+/-0.6 mol%. In addition, DNA-DNA hybridization data supported the placement of the isolate in a new species in the genus Natrialba, Natrialba aegyptiaca sp. nov., and indicated that Natrialba asiatica strain B1T should also be placed in a separate species, Natrialba taiwanensis sp. nov. Morphological studies of strain 40T indicated clearly that this isolate appears in three completely different cell shapes (cocci, rods, tetrads) under different conditions of growth, including different sodium chloride concentrations and different growth temperatures. Another interesting property of strain 40T is the ability to produce an extracellular polymer, which was found to be composed predominantly of glutamic acid (85% w/w), representing poly(glutamic acid), carbohydrates (12.5% w/w) and unidentified compounds (2.5% w/w). Among the Archaea, production of an extracellular polysaccharide has been described for some members of the genera Haloferax and Haloarcula.

Three strains, CLM-U50 T , CLM-R50 and IVIC-Bov1, belonging to the genus Leptospira, were isolated in Venezuela from a patient with leptospirosis, a domestic rat (Rattus norvegicus) and a cow (Bos taurus), respectively. The initial characterisation of these strains based on the rrs gene (16S rRNA) suggested their designation as a novel species within the 'intermediates' group of the genus Leptospira. Further phylogenomic characterisation based on single copy core genes was consistent with their separation into a novel species. The average nucleotide identity between these three strains was >99 %, but below 89 % with respect to any previously described leptospiral species, also supporting their designation as a novel species. Given this evidence, these three isolates were considered to represent a novel species, for which the name Leptospiravenezuelensis sp. nov. is proposed, with CLM-U50 T (=CIP 111407 T =DSM 105752 T ) as the type strain.

The 99m Tc is used for diagnosis and therapy. It is produced commercially from 99 Mo obtained from the fission of 235 U, which is retained in chromatographic columns filled with alumina whose maximum capacity is 0.2%. Given these constraints new methods of preparation 99 Mo/ 99m Tc generators have been developed using zirconium molybdates gels containing up to 30% of Mo, which is part of the generator matrix, and retaining quality and purity similar characteristics to those commercial generators. The present study aims to determine the flow of agitation, temperature and drying time optimal to prepare 99 Mo/ 99m Tc generators based on 99 Mo zirconium molybdates in the Gel Synthesis Device 99 Mo/ 99m Tc Generators designed and built by groups of the Radioactive Materials Research Laboratory and Automation and Instrumentation Department of the National Institute of Nuclear Research.
