Frontlog Cataloging: Using In-Process Records to Reveal Backlogged Collections
Authors: Nof Jasmin
Published: August 2013

The University of Maryland Libraries have acquired tens of thousands of Judaica volumes during the past decades and continuing to the present. The growth has far exceeded cataloging capacity, resulting in a significant backlog that is invisible to selectors and patrons alike. In order to make these materials available, catalogers at UM Libraries developed procedures that make use of in-process records. These processes have since been applied to other backlogs. This paper describes the procedures and discusses their advantages and disadvantages. Overall, the frontlog approach has resulted in visible benefits to both patrons and librarians.

Published: August 2013

Background: Preanalytical conditions encountered during collection, processing, and storage of biospecimens may influence laboratory results. The National Children’s Study (NCS) is a planned prospective cohort study of 100,000 families to examine the influence of a wide variety of exposures on child health. In developing biospecimen collection, processing, and storage procedures for the NCS, we identified several analytes of different biochemical categories for which it was unclear to what extent deviations from NCS procedures could influence measurement results.

Methods: A pilot study was performed to examine effects of preanalytic sample handling conditions (delays in centrifugation, freezing delays, delays in separation from cells, additive delay, and tube type) on concentrations of eight different analytes. A total of 2825 measurements were made to assess 15 unique combinations of analyte and handling conditions in blood collected from 151 women of childbearing age (≥20 individuals per handling condition).

Results: The majority of analytes were stable under the conditions evaluated. However, levels of plasma interleukin-6 and serum insulin were decreased in response to sample centrifugation delays of up to 5.5 h post-collection (p<0.0001). In addition, delays in freezing centrifuged plasma samples (comparing 24, 48 and 72 h to immediate freezing) resulted in increased levels of adrenocorticotropic hormone (p=0.0014).

Conclusions: Determining stability of proposed analytes in response to preanalytical conditions and handling helps to ensure high-quality specimens for study now and in the future. The results inform development of procedures, plans for measurement of analytes, and interpretation of laboratory results.
Nitrous oxide for analgesia in external cephalic version at term: prospective comparative studya
Authors: Burgos Jorge , Cobos Patricia , Osuna Carmen , de Mar Centeno María , Fernández-Llebrez Luis , Astorquiza Txanton Martinez , Melchor Juan Carlos
Published: August 2013

Objective: The objective of this study was to analyze the effect of using inhaled nitrous oxide (N2O) for analgesia in external cephalic version (ECV) at term on the success rate of the procedure, on pain, and on obstetric and perinatal outcomes.

Methods: A prospective comparative cohort study among 300 women with singleton pregnancy in breech presentation at term undergoing an ECV with inhaled N2O in a 50:50 mix with oxygen for analgesia and 150 ECVs with no analgesia.

Results: The success rate was 52.3% in the N2O cohort and 52.7% in the controls (P=0.94), whereas the median level of pain was statistically lower in women given N2O (median, 6; range, 4–7, vs. median, 7; range, 5–8; P<0.01). This improvement is mainly from a 49% decrease in severe pain. There were no significant differences in the rate of complications associated with the ECV, in the rate of cesarean sections, or in perinatal outcomes. Furthermore, there were no severe complications secondary to N2O inhalation.

Conclusions: N2O inhalation at a concentration of 50% for analgesia during ECV decreases the level of severe pain experienced by women, appears to be safe both for mother and child, and has no influence on the success rate of ECV or the perinatal outcomes.
Studies on thin films of PVC-PMMA blend polymer electrolytes
Authors: Khan Mohammad Saleem , Gul Rahmat , Wahid Mian Sayed
Published: August 2013

Thin films of poly (vinyl chloride) (PVC)/poly (methyl methacrylate) (PMMA) blend polymers complexed with different concentrations of LiClO4 salt, containing ethylene carbonate (EC) as the plasticizer, were fabricated by the solution cast procedure. Ionic conductivity, thermal stability and X-ray diffraction (XRD) studies were undertaken. AC impedance measurements were done in the temperature range of 20–70°C. The highest ionic conductivity at room temperature was found to be 2.23×10-5 S cm-1 for the sample containing 15 wt% of LiClO4 salt. The XRD technique was used to investigate the structure and complex formation of solid polymer electrolytes. There was a decrease in degree of crystallinity. The amorphous nature of complexed solid polymer blend electrolyte films increased, due to the addition of LiClO4 salt. Thermogravimetric analysis (TGA) and differential thermal analysis (DTA) revealed the effect of salt on the thermal stability of the polymer electrolytes. It was found that these polymer electrolyte systems show stability up to about 280°C. It was also found that, with increased LiClO4 salt content in complexed polymer electrolyte systems, the degradation temperature decreased.

Published: August 2013

In this study, the boundary element method is presented for the prediction of longitudinal modulus of aligned discontinuous fiber-reinforced composites. The details of the boundary element formulation model covering infinite friction (stick) contact conditions are given. Both fiber and matrix materials are assumed to display linear elastic material behavior. The formulation is applied to boron/epoxy discontinuous fiber-reinforced composites. The computed results show a very good agreement with the modified Cox model and the finite element analysis with experimental data.
Ez 1 – verständlich unverständlich
Authors: Wagner Thomas
Published: August 2013

Abstract: The analysis of the contrasting use of the pronominal suffixes in Ezek 1 shows that this has different functions. It is used both as a literary »bracket« and for the distinction between the parts of the body, or rather the individual objects, and the totality. Treated form-critically, the lack of a logical narrative structure and the stringing together of nominal clauses serve to make the succession of images appear as a sequence of separate scenes. This mode of presentation is chosen by the author because of the alternation between light and darkness in the appearance of the creatures which is described in v. 13. Finally, the concluding test of coherence demonstrates that vv. 14.15–21.23b1–4.25.27bβ are redactional expansions of the original text.

Résumé: L’analyse de l’usage adversatif des préfixes pronominaux en Ez. 1 montre que celui-ci recouvre des fonctions diverses. Il est utilisé à la fois comme parenthèse littéraire et comme mode de distinction entre les parties du corps, respectivement des objets individuels ou de ceux de la collectivité. D’un point de vue formel, cette absence de structure narrative logique, ainsi que l’accumulation de phrases nominales, servent à présenter la série des images comme autant de séquences isolées. Ce mode de représentation est choisi par l’auteur afin d’obtenir une vision des êtres selon une description en »clair-obscur«, sur la base du v. 13. Une analyse finale de la cohérence du texte montre que les vv. 14.15–21.23b1–4.25.27bβ constituent des adjonctions rédactionnelles.

Zusammenfassung: Die Analyse des adversativen Gebrauchs der Pronominalsuffixe in Ez 1 zeigt, dass dieser unterschiedliche Funktionen besitzt. Er wird als literarische Klammer sowie zur Unterscheidung zwischen den Körperteilen der einzelnen Objekte und denen der Gesamtheit verwendet. Formkritisch betrachtet dienen die fehlende logische narrative Struktur sowie die Aneinanderreihung von Nominalsätzen dazu, die Bildfolge als Schau von einzelnen Sequenzen er scheinen zu lassen. Diese Darstellungsform wird vom Verfasser aufgrund des in V. 13 beschriebenen Hell-Dunkel-Wechsels bei der Schau der Wesen gewählt. Die abschließende Kohärenzprüfung weist schließlich nach, dass die V. 14.15–21.23b1–4.25.27bβ redaktionelle Erweiterungen sind.
Singing Translations
Authors: Tunbridge Laura
Published: August 2013

British attitudes toward German-language song repertoire were transformed in the interwar period by a potent combination of politics and technology. The use of translations gained and lost ground; native musicians struggled to compete with international stars; and new listening strategies developed around the gramophone and radio. In the process, notions of cosmopolitan connoisseurship became established that still dominate reception and performance practices today.
The management of head-and-neck paragangliomas
Authors: Capatina Cristina , Ntali Georgia , Karavitaki Niki , Grossman Ashley B
Published: August 2013

Paragangliomas (PGLs) are tumours originating from neural crest-derived cells situated in the region of the autonomic nervous system ganglia. Head-and-neck PGLs (HNPGLs) originate from the sympathetic and parasympathetic paraganglia, most frequently from the carotid bodies and jugular, tympanic and vagal paraganglia, and are usually non-catecholamine secreting. Familial PGLs are considered to be rare, but recently genetic syndromes including multiple PGLs and/or phaeochromocytomas have been more thoroughly characterised. Nowadays, genetic screening for the genes frequently implicated in both familial and sporadic cases is routinely being recommended. HNPGLs are mostly benign, generally slow-growing tumours. Continuous growth leads to the involvement of adjacent neurovascular structures with increased morbidity rates and treatment-related complications. Optimal management mostly depends on tumour location, local involvement of neurovascular structures, estimated malignancy risk, patient age and general health. Surgery is the only treatment option offering the chance of cure but with significant morbidity rates, so a more conservative approach is usually considered, especially in the more difficult cases. Radiotherapy (fractionated or stereotactic radiosurgery) leads to tumour growth arrest and symptomatic improvement in the short term in many cases, but the long-term consequences are unclear. Early detection is essential in order to increase the chance of cure with a lower morbidity rate. The constant improvement in diagnostic imaging, surgical and radiation techniques has led to a safer management of these tumours, but there are still many therapeutic challenges, and no treatment algorithm has been agreed upon until now. The management of HNPGLs requires a multidisciplinary effort addressing the genetic, surgical, radiotherapeutic, oncological, neurological and endocrinological implications. Further progress in the understanding of their pathogenesis will lead to more effective screening and earlier diagnosis, both critical to successful treatment.

Published: August 2013

In this study, we i) assessed the metabolic profile of the normal adrenal cortex and medulla of adult human subjects by means of1H-high-resolution magic-angle spinning nuclear magnetic resonance (HRMAS NMR) spectroscopy; ii) compared the biochemical profile of adenoma (Ad), adrenal cortical carcinoma (ACC), and pheochromocytoma (PCC) samples with that of healthy adrenal tissue samples; and iii) investigated the metabolic differences between ACCs and Ads as well as between ACCs and PCCs. Sixty-six tissue samples (13 adrenal cortical tissue, eight medullary tissue, 13 Ad, 12 ACC, and 20 PCC samples) were analyzed. Adrenaline and noradrenaline were undetectable in cortical samples representing the metabolic signature of the tissue derived from neural crest. Similarity between the metabolic profile of Ads and that of the normal adrenal cortex was shown. Inversely, ACC samples clearly made up a detached group exhibiting the typical stigmata of neoplastic tissue such as choline-containing compounds, biochemical markers of anaerobic processes, and increased glycolysis. Significantly higher levels of lactate, acetate, and total choline-containing compounds played a major role in the differentiation of ACCs from Ads. Moreover, the high fatty acid content of ACCs contributed to the cluster identification of ACCs. Of the 14 sporadic PCC samples, 12 exhibited predominant or exclusive noradrenaline secretion. The noradrenaline:adrenaline ratio was inverted in the normal medullary tissue samples. Multiple endocrine neoplasia type 2- and NF1-related PCC samples exhibited both adrenaline and noradrenaline secretion. In the von Hippel–Lindau disease-related PCC samples, only noradrenaline secretion was detected by HRMAS NMR spectroscopy. This study is one of the first applications of metabolomics to adrenal pathophysiology and it is the largest study to report HRMAS NMR data related to the adrenal cortex and adrenal cortical tumors.
Inferring Selection Intensity and Allele Age from Multilocus Haplotype Structure
Authors: Chen Hua , Slatkin Montgomery
Published: August 2013

It is a challenging task to infer selection intensity and allele age from population genetic data. Here we present a method that can efficiently estimate selection intensity and allele age from the multilocus haplotype structure in the vicinity of a segregating mutant under positive selection. We use a structured-coalescent approach to model the effect of directional selection on the gene genealogies of neutral markers linked to the selected mutant. The frequency trajectory of the selected allele follows the Wright-Fisher model. Given the position of the selected mutant, we propose a simplified multilocus haplotype model that can efficiently model the dynamics of the ancestral haplotypes under the joint influence of selection and recombination. This model approximates the ancestral genealogies of the sample, which reduces the number of states from an exponential function of the number of single-nucleotide polymorphism loci to a quadratic function. That allows parameter inference from data covering DNA regions as large as several hundred kilo-bases. Importance sampling algorithms are adopted to evaluate the probability of a sample by exploring the space of both allele frequency trajectories of the selected mutation and gene genealogies of the linked sites. We demonstrate by simulation that the method can accurately estimate selection intensity for moderate and strong positive selection. We apply the method to a data set of the G6PD gene in an African population and obtain an estimate of 0.0456 (95% confidence interval 0.0144−0.0769) for the selection intensity. The proposed method is novel in jointly modeling the multilocus haplotype pattern caused by recombination and mutation, allowing the analysis of haplotype data in recombining regions. Moreover, the method is applicable to data from populations under exponential growth and a variety of other demographic histories.
Mutational Analysis of Sse1 (Hsp110) Suggests an Integral Role for this Chaperone in Yeast Prion PropagationIn Vivo
Authors: Moran Ciara , Kinsella Gemma K , Zhang Zai-Rong , Perrett Sarah , Jones Gary W
Published: August 2013

The yeast Hsp110 chaperone Sse1 is a conserved protein that is a noncanonical member of the Hsp70 protein superfamily. Sse1 influences the cellular response to heat stress and has also been implicated in playing a role in the propagation of prions in yeast. Sse1 can seemingly exert its effects in vivo through direct or indirect actions by influencing the nucleotide exchange activity of canonical cytosolic Hsp70s. Using a genetic screen based on the inability to propagate the yeast [PSI+] prion, we have identified 13 new Sse1 mutants that are predicted to alter chaperone function through a variety of different mechanisms. Not only are these new Sse1 mutants altered in the ability to propagate and cure yeast prions but also to varying degrees in the ability to grow at elevated temperatures. The expression levels of chaperone proteins known to influence yeast prion propagation are unaltered in the Sse1 mutants, suggesting that the observed phenotypic effects are caused by direct functional alterations in these mutants. Mapping the location of the mutants onto the Sse1 crystal structure suggests that more than one functional alteration in Sse1 may result in changes in prion propagation and ability to function at elevated temperatures. All Sse1 mutants isolated provide essential functions in the cell under normal growth conditions, further demonstrating that essential chaperone functions in vivo can to some degree at least be detached from those related to propagation of prions. Our results suggest that Sse1 can influence prion propagation through a variety of different mechanisms.
A Case Report of Obsessive-Compulsive Disorder Following Acute Disseminated Encephalomyelitis
Authors: Muir Katherine E. , McKenney Katherine S. , Connolly Mary B. , Stewart S. Evelyn
Published: August 2013

We present a case of a boy who developed obsessive-compulsive disorder (OCD) shortly after an episode of acute disseminated encephalomyelitis (ADEM). To our knowledge, this is the first report of the development of OCD in a child who has had ADEM. This presentation is consistent with our understanding of OCD as a complex genetic disease involving the cerebral white matter tracts, and may indicate a potential pathway for the development of OCD in genetically vulnerable individuals or a shared trigger for the development of pediatric acute-onset neuropsychiatric syndrome and ADEM.
Synthesis of Samarium Oxide Films by Pulsed Laser Deposition
Authors: Yang Dongfang , Xue Lijue
Published: August 2013

Uniform Samarium oxide (Sm203) films were grown on 75-mm diameter silicon wafers by the pulsed laser deposition (PLD) technique. The beam of a KrF excimer laser was used to ablate an Sm2O3 target in an oxygen pressure of 30 mTorr. The crystal structure, surface morphology and optical properties of Sm2O3 films deposited at a temperature range of 25∼680°C were determined by XRD, FE-SEM, and spectra reflectance respectively. Monoclinic structure was the predominant phase for Sm2O3 films deposited at temperatures of 680°C and 400°C. Amorphous or partially crystallized amorphous phase was observed at deposition temperatures of 25°C and 200°C. The Sm2O3 film deposited at 680°C is very dense, while films deposited at lower temperatures have higher porosity. The values of index of refraction, n, and extinction coefficient, k, at λ = 633 nm are 1.867 and 0.0660, respectively, for the 680°C film, and are in a range of 1.5∼1.6 and 0.01∼0.04 respectively for films deposited at lower temperatures.
Como entender a vaidade feminina utilizando a autoestima e a personalidade
Authors: Avelar Cátia Fabíola Parreira de , Veiga Ricardo Teixeira
Published: August 2013

O artigo busca compreender a relação da autoestima e variáveis de personalidade na vaidade feminina e como essas associações podem influenciar a propensão de buscar cirurgias plásticas estéticas (CPEs). Usando o modelo 3M (MOWEN, 2000) , realizou-se um levantamento com 697 alunas de uma universidade federal brasileira, com idade entre 18 e 50 anos. Vaidade foi operacionalizada por dois traços: preocupação com aparência, que consiste em uma observação exagerada da aparência física, e visão vaidosa, referente à avaliação excessivamente positiva da própria aparência. Os principais achados in- dicam que quanto maior a criatividade, extroversão, amabilidade e necessidade de manter e de realçar o corpo, maior será a autoestima, e quanto maior a autoestima, menor a preocupação exagerada com a aparência física e maior a avaliação positiva que uma mulher faz de sua aparência. Mulheres materialistas e com necessidade maior de recursos corporais são mais excessivamente preocupadas com a aparência. A influência da vaidade na propensão à CPE deu-se por meio do traço preocupação com aparência.
Negociação com informação privilegiada e retorno das ações na BM&FBOVESPA
Authors: Martins Orleans Silva , Paulo Edilson , Albuquerque Pedro Henrique Melo
Published: August 2013

No Brasil, conforme a Lei nº 10.303/2001, o uso indevido de informação privilegiada no mercado acionário é crime. Contudo, na literatura, é possível encontrar estudos que apontam a existência de negociações com informação privilegiada nesse mercado (BOPP, 2003; BARBEDO, SILVA, LEAL, 2009). Por isso, este estudo tem o objetivo de investigar a probabilidade de negociação com informação privilegiada (PIN) na negociação de ações na BM&FBOVESPA, buscando identificar sua relação com o retorno dessas ações. Com base nas Teorias dos Mercados Eficientes e da Agência, foram analisadas 198 ações durante o ano de 2011. Por meio do modelo de mensuração de assimetria de informação de Easley, Hvidkjaer e O'Hara (2002), a PIN foi estimada e relacionada ao retorno das ações por meio do modelo de Fama e MacBeth (1973) ajustado. Os resultados indicam que há 22,9% de probabilidade de terem ocorrido negociações com informação privilegiada, que os segmentos com maiores exigências de governança reúnem as ações com menor assimetria e que um aumento de 10,0% na PIN leva a um aumento de 8,0% no retorno das ações.
Influence of Compound 16.842 on hookworm infections
Authors: Silva J. Rodrigues da , Camillo-Coura Léa
Published: August 2013

Compound 16.842 was tried with three different groups of patients in order to evaluate its tolerancy, and efficacy as well, with a view of using the drug in mass campaigns against hookworm. Group I, used for a preliminary trial, consisted of 38 patients attending an out-patient clinic, and living either in the out-skirts or in the various urban areas of the city of Rio de Janeiro, including some inmates of an orphanage. Group II, a field trial, was carried out in two farms, where the drug was administered both to the positive cases (124) and to the rest of the population (nearly 90%). Group III, a field trial was also carried out in a small town where nearly 40% of the total population was treated with the Compound. Tolerability was considered rather satisfactory, mainly among the patients receiving two single doses (50-150mg), according to the age, 4 - 6 weeks apart). These results suggest that 2-4 courses of therapy within a shorter span of time should be the ideal for a mass treatment campaign. Efficacy varied from 26.6% to 76.2% parasitological cure in the various groups, with a wide range of variation also in the percent of mean reduction of eggs for hookworm. The drug showed also some effect against Ascaris lumbricoides giving cure rates between 10,5% and 35.7% in the various groups, with a percentage reduction in mean egg counts of 27% to 83.3% according to the various groups. It was concluded that Compound 16.842 possesses a marked effect on hookworm and a mild effect on A. lumbricoides. The findings indicate the need for more accurate studies to determine the most efficient schedules of treatment and the real value of the drug, as compared to other antihelminthics against the two parasites under study.
Investigações sôbre inibidores para o vírus da poliomielite, presentes em soros de bovinos
Authors: Schatzmoryr Hermann G.
Published: August 2013

Inibidores contra as amostras de poliovírus do tipo 1, Mahoney e CHAT, foram estudados no sistema de gel de hidróxido de alumínio. O inibidor comportou-se como uma macroglobulina do tipo 19 S (IgM), através filtração em gel (Sephadex G-200), partição em DEAE-Celulose e sedimentação por ultra-centrifugação em gradiente de sacarose. O inibidor foi ainda destruído através o tratamento com 2-Mercapto-Etanol. O inibidor une-se à superfície do vírus na ausência de células. O complexo formado pelo vírus e o inibidor pode ser precipitado por um sôro preparado contra a globulina bovina; o mesmo complexo dissocia-se em idêntico valor de pH ao do complexo vírus-anticorpo 19 S. A chamada infecciosidade residual (cêrca de 10%) que permanece após a neutralização de poliovírus com sôro bovino representa uma dissociação parcial do inibidor da partícula de vírus, quando em presença das células em cultura. Foram obtidas amostras de vírus resistentes à ação específica de soros bovinos. Estas amostras permanecem sensíveis à ação de outros soros bovinos ativos, bem como à ação de anticorpos 7 S e 19 S. Através experiências de adsorção de atividade inibidora, foi possível mostrar a existência de inibidores monoespecíficos, com diferentes especificidades contra as amostras CHAT e Mahoney, respectivamente.
Experimental chemotherapy of Schistosomiasis III: laboratory and clinical trials with trichlorphone, an organophosphorus compound

Published: August 2013

Oogram studies have been carried out on mice, hamsters, and Cebus morikeys experimentally infected with Schistosoma mansoni and treated with trichlorphone (0,0-dimethyl 1-hydroxy-2, 2, 2-trichloroethylphosphonate). In mice, despite a slight hepatic shift of schistosomes, all animais presented oogram changes when dosed, per os, at the schedules of 200, and 100 mg/kg/day × 7. In hamsters, antischistosomal activity could be detected only at toxic leveis. In monkeys, trichlorphone showed insignificant action even after oral administration of 30 mg/kg/day for 10 consecutive days. In 5 volunteers, a sharp drop in cholinesterase plasma level was observed 24 hours after a single oral dose of 7.5 mg/kg. However, cholinesterase levels returned to the initial values within a period of 11 to 27 days. Trichlorphone was then administered to 12 schistosome patients (7.5 mg/kg/day, every fort- night, × 5). One month after therapy, interruption of egg laying was observed in 6 patients. Late parasitological control showed that all treated patients continued to pass viable S. mansoni eggs with their stools.

Em face à predominante eliminação biliar da rifamicina S.V. atingindo concentrações muitas vêzes superiores aos níveis séricos obtidos com as doses terapêuticas, e pelo possível interêsse dessa verificação para o tratamento dos portadores biliares crônicos de Salmonella typhi determinou-se a concentração mínima inibitória de 165 estirpes de enterobactérias, incluindo 77 amostras de S. typhi. Foi verificado que a maioria das cepas de Escherichia coli, Shigella e Proteus mirabilis correspondiam a uma concentração inibitória mínima entre 33 a 65 μg/ml. Entre 65 e 128 μg/ml foram determinadas as concetrações inibitórias mínimas da maioria das outras espécies de Proteus, de Providencia e de Klebsiella. Para Salmonella e Enterobacter o limite mínino de sensibilidade foi, em regra, igual ou superior a 128 μg/ml. Diferenças mais acentuadas de comportamento entre as enterobactérias foram observadas quanto à ação bactericida da rifamicidas S.V. De uma maneira geral, para E. coli e Shigella, as concentrações inibitórias mínimas já referidas. Para as espécies de Proteus e Providencia houve variação maior de comportamento, mas tendência a que o efeito bactericidas fôsse encontrado em concentrações que correspondiam a 4 vêzes as bacteriostáticas para as mesmas espécies. Finalmente, de modo pouco feliz para os propósitos visados, em Salmonella, com a inclusão de S. typhi, não foi atingido um efeito bactericida, com as mais altas concentrações usadas as quais corresponderam em média a 6 vêzes as concentrações bacteriostáticas para esse gênero.

Published: August 2013

This study evaluated the effect of initial pH values of 4.5, 6.5 and 8.5 of the attractant (protein bait) Milhocina® and borax (sodium borate) in the field, on the capture of fruit flies in McPhail traps, using 1, 2, 4 and 8 traps per hectare, in order to estimate control thresholds in a Hamlin orange grove in the central region of the state of São Paulo. The most abundant fruit fly species was Ceratitis capitata, comprising almost 99% of the fruit flies captured, of which 80% were females. The largest captures of C. capitata were found in traps baited with Milhocina® and borax at pH 8.5. Captures per trap for the four densities were similar, indicating that the population can be estimated with one trap per hectare in areas with high populations. It was found positive relationships between captures of C. capitata and the number of Hamlin oranges damaged, 2 and 3 weeks after capture. It was obtained equations that correlate captures and damage levels which can be used to estimate control thresholds. The average loss caused in Hamlin orange fruits by C. capitata was 2.5 tons per hectare or 7.5% of production.

As moscas-das-frutas (Diptera: Tephritidae) são pragas-chave na cultura da goiabeira Psidium guajava L., com predominância de diferentes espécies de acordo com a região produtora no Brasil. Os objetivos do presente trabalho foram conhecer a diversidade e analisar parâmetros faunísticos das moscas-das-frutas obtidas em um pomar de goiabeira, no município de Cruzeta, Rio Grande do Norte, situado no semiárido brasileiro. As moscas-das-frutas foram coletadas semanalmente, com auxílio de armadilhas McPhail, tendo como atrativo proteína hidrolisada a 5% v/v. Foram registradas cinco espécies no pomar estudado: Ceratitis capitata (Wied.), Anastrepha zenildae Zucchi, Anastrepha sororcula Zucchi, Anastrepha obliqua (Macquart) e Anastrepha dissimilis Stone. Ceratitis capitata foi a espécie mais frequente, constante e dominante, considerada como uma praga invasiva, potencial em pomares de goiabeira no semiárido brasileiro.

Published: August 2013

A meloidoginose da goiabeira, causada por M. enterolobii (= M. mayaguensis), é hoje considerado o principal problema fitossanitário desta cultura em todo o País, pois sua incidência resulta em acentuada queda de produtividade e, na maioria das vezes, a morte das plantas em médio prazo. Visando a seu controle, objetivou-se neste trabalho identificar fontes de resistência em goiabeira Psidium guajava L e araçazeiro Psidium sp.. Foram avaliados onze genótipos oriundos do Câmpus da Universidade Federal de Lavras (UFLA) e de regiões próximas ao município de Lavras (MG). As sementes foram coletadas de frutos fisiologicamente maduros e germinadas em piscinas hidropônicas. Ao atingirem 12 cm de altura, foram transferidas para casa de vegetação, em vasos individuais, e mantidas a temperatura entre 18-38°C. Após quinze dias, foram inoculados individualmente com suspensão de 10.000 ovos e juvenis de segundo estádio (J2) de M. enterolobii e avaliadas após 120 dias. As reações dos hospedeiros foram enquadradas nos parâmetros estabelecidos pelo fator de reprodução FR, estimado pelo quociente Pf/Pi, em que Pf representa a população final e Pi a população inicial. O delineamento utilizado foi o inteiramente casualizado, com 11 genótipos, uma espécie de nematoide e seis repetições, sendo duas plantas em cada genótipo adicionadas como controle. Quatro meses depois, foram avaliados os teores foliares de macro e micronutrientes e o grau de infecção de cada genótipo. A produção média de ovos e J2 de M. enterolobii variou de 200 a 428.146,1, e os fatores de reprodução (FR) médios variaram de 0,02(ALU1) a 42,81(A-PASTO). Os genótipos de araçazeiro (Psidium spp.) AUFLA1, AUFLA4, AUFLA5 e APASTO e os genótipos de goiabeira (P. guajava) G-ROXA e G-AMAR foram considerados suscetíveis. Os genótipos de araçazeiro ALU1, ALU2, ALU3, AROXO-C e AROXO-U mostraram-se resistentes, reforçando a necessidade de trabalhos complementares com essas espécies para uso como porta-enxerto em cultivares comerciais de goiabeira. A absorção de macro e micronutrientes é alterada quando os genótipos de Psidium spp. são inoculados com o fitonematoide M. enterolobii.

Published: August 2013

Este trabalho teve como objetivo avaliar as características morfológicas e os aspectos físicos, físico-químicos e químicos das plantas e dos frutos de 15 variedades de laranjas cedidas pelo Centro Nacional de Pesquisa de Mandioca e Fruticultura (Embrapa - CNPMF), e plantadas na Estação Experimental do Instituto Agronômico de Pernambuco, Brejão-PE. Foram avaliados: diâmetro do caule acima e abaixo da linha de enxertia e a relação entre eles, diâmetro da copa, altura da planta e volume de copa. Nos frutos, as avaliações consistiram em: formato, coloração do epicarpo, massa do fruto, massa do suco, altura e diâmetro do fruto, espessura do mesocarpo e do endocarpo, número de sementes por fruto e rendimento em suco. O delineamento experimental foi em blocos casualisados, com quatro repetições e uma planta por parcela. Para o aspecto qualitativo dos frutos, utilizou-se o mesmo delineamento, e foram avaliados através de 12 descritores. Apenas seis das variedades de laranjas estudadas estão dentro das exigências do Programa Brasileiro para a Modernização da Horticultura e cinco das variedades de laranjas mostraram-se com maturação diferente das descritas na literatura.

A produção de mudas de espécies frutíferas com qualidade é realizada em ambiente protegido que, em função das variações da temperatura do ar, necessita de irrigação frequente para manter a umidade no substrato. Desta forma, o trabalho foi realizado com o objetivo de avaliar diferentes frequências de irrigação com a incorporação do polímero hidroabsorvente na produção de mudas de maracujazeiro-amarelo em dois tipos de substrato. As mudas foram produzidas em sacos de polietileno de 650 mL em casa de vegetação. Foi utilizado o esquema fatorial 2 x 2 x 3, distribuído no delineamento inteiramente casualizado, com quatro repetições e cinco plantas por parcela, sendo uma por recipiente. Os fatores estudados foram duas doses do polímero Hidroplan-EB®/HyB-M (0 e 3 g L-1); dois substratos (solo + esterco na proporção 3:1 (v/v) e Bioplant®); e três intervalos de reposição de água (irrigação diária, irrigação em dias alternados e irrigação a cada dois dias). Para analisar o efeito comparativo da incorporação do polímero aos substratos, a avaliação foi realizada quando as mudas emitiram a primeira gavinha, estágio ideal para o plantio no campo. A incorporação do polímero aos substratos proporcionou tamanho das mudas, que foi evidenciado a partir da maior produção de massa seca. Além disso, essas mudas, mesmo com menor frequência de irrigação, apresentaram tamanho semelhante às mudas que receberam irrigação diária e área foliar com maior capacidade de produção de massa seca. Assim, com a incorporação do polímero hidroabsorvente, a irrigação das mudas de maracujazeiro pode ser realizada com menor frequência, com intervalo de um dia em ambos os substratos. A formação das mudas de maracujazeiro-amarelo foi antecipada nos substratos que tiveram incorporação do polímero, alcançando tamanho adequado para o plantio no campo antes daquelas produzidas sem o polímero.

O presente trabalho teve como objetivo quantificar a divergência genética entre 138 acessos de goiabeira procedentes do banco de germoplasma da Universidade Estadual do Norte Fluminense Darcy Ribeiro (UENF), com base em descritores morfológicos, agronômicos e físico-químicos, por meio do procedimento Ward - Modified Location Model (MLM). Para tanto, foram avaliados 13 descritores, sendo cinco qualitativos (coloração da polpa, superfície do fruto, formato do fruto ao final do pedúnculo, largura do pescoço e uniformidade da cor da polpa) e oito quantitativos (massa média do fruto, diâmetro longitudinal do fruto, diâmetro transversal do fruto, rendimento da polpa, teor de sólidos solúveis totais, acidez do fruto, relação teor de sólidos solúveis totais e acidez do fruto e teor de ácido ascórbico). Detectou-se ampla variabilidade genética pelos dados morfológicos, agronômicos e físico-químicos nos 138 acessos de goiaba. Pelo procedimento da função da verossimilhança, determinou-se oito o número ideal de grupos, com um valor de incremento de 67,51. O grupo III foi considerado o mais distante, enquanto os grupos I, II, IV, V e VI, os mais próximos. O procedimento Ward-MLM é uma ferramenta útil para detectar divergência genética e agrupar os acessos utilizando, simultaneamente, variáveis qualitativas e quantitativas.
CS-ASA: a new computational tool for advanced analysis of steel frames
Authors: Silva Andréa Regina Dias da , Prado Ícaro Machado , Silveira Ricardo Azoubel da Mota
Published: August 2013

A new computational tool for advanced static and dynamic analyses of steel framed structures based on the Finite Element Method has been developed and is presented herein. Two sources of nonlinearity can be considered in these analyses, i.e.: the geometric, which considers the nonlinear effects of structure displacements; and the physical, which considers the nonlinear effects of the mechanical characteristics of the material used in civil construction. Loading, geometric and residual stress imperfections can also be considered. To illustrate some of the features and capabilities that differentiate this tool from existing commercial programs, static and dynamic stability analyses of some structural systems with rigid and semi-rigid connections are evaluated. The results obtained by other researchers are used to validate the nonlinear formulations and numerical solution methodologies implemented in CS-ASA, and to attest the efficiency of the structural analysis program presented herein.
