OLVIDOS Y RECUERDOS DE UN MONTAJE COMUNICACIONAL. Una aproximación a las memorias subterráneas de ex militantes del Movimiento de Izquierda Revolucionaria en Chile
Authors: RUIZ María Olga
Published: October 2016

RESUMEN Este trabajo se aproxima a un acontecimiento escasamente investigado y que, sin embargo, circula como una memoria subterránea entre los sobrevivientes y ex militantes del Movimiento de Izquierda Revolucionario; me refiero a la llamada Conferencia de Prensa de Villa Grimaldi, montaje comunicacional organizado por la DINA (Dirección de Inteligencia Nacional) que tuvo como protagonista a un grupo de militantes de esta organización que se encontraban secuestrados en el Cuartel Terranova (Villa Grimaldi). El operativo consistió en que los prisioneros llamaran públicamente a deponer la resistencia armada en contra de la dictadura, declarando la derrota política y militar del MIR. Una vez realizado el montaje, los cuatro militantes fueron acusados de traición y condenados a muerte por ésta organización, medida que finalmente no se implementó. En este artículo me aproximo a las diversas memorias (muchas de ellas en conflicto) que existen en torno a este acontecimiento, incluyendo el testimonio de sus dos sobrevivientes.

ABSTRACT Objective: The aim of this study was to assess the impact of socioeconomic factors and clinical conditions on the child oral health-related quality of life (COHRQoL) of preschool children. Methods: A cross-sectional study was conducted with a representative sample of 547 children of 0-5-years-old from Santa Maria, RS, Brazil, in 2013. Data were collect in the National Children's Vaccination Day Program by calibrated dentists. Clinical examinations assessed the prevalence of dental caries and dental trauma. Information about children's socioeconomic status was collected through a structured questionnaire answered by parents/caregivers. The COHRQoL was measured using the Brazilian version of the Early Childhood Oral Health Impact Scale (ECOHIS). Multivariable Poisson regression models were performed to assess the association between clinical conditions, socioeconomic status and COHRQoL. Results: The prevalence of dental caries and dental trauma were 16.42 % and 22.49%, respectively. Higher means of the ECOHIS were found in older children, those with toothache and those whose mother had lower level of formal education. The clinical conditions that have been associated with negative impact on oral health related quality of life were experience caries (RR 4.12; 95% CI 3.10-5.46) and dental trauma (RR 1.37; 95% CI 1.01-1.86). Conclusion: Poor socioeconomic and clinical conditions had a negative impact on the COHRQoL, indicating the need of preventive strategies and policies aiming at improving the quality of life of this sample.
Age of the emerald mineralization from the Itabira-Nova Era District, Minas Gerais, Brazil, based on LA-ICP-MS geochronology of cogenetic titanite

Published: October 2016

ABSTRACT: In the Itabira-Nova Era Emerald District, southeast Brazil, gemological emerald is extracted from underground mines found in schist-type deposits at the contact zone of the Archean Metavolcanosedimentary Sequence of the Guanhães Complex and Paleoproterozoic anorogenic granites of the Borrachudos Suite. Schist-type deposits are commonly generated by reactions enhanced by deformation and heat during regional metamorphism. The age of the mineralization in the region has been a matter of debate for decades: Ages ranging from the Archean to the Neoproterozoic are mentioned in the literature. In the mineralized zone from the Piteiras mine fluorine-aluminum-bearing titanite is found in metamafic rocks. The fluorine content was probably derived from the Borrachudos granites and pegmatites like the beryllium for emerald, thus both minerals could have been generated during the same event. U-Pb titanite geochronology via laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS) was performed on a thin section of a phlogopite-plagioclase-hornblende schist from the Piteiras mine. The determined age of 576 ± 7 Ma is also the probable age for emerald generation during the Brasiliano cycle, which was the only tectonometamorphic event postdating the intrusion of the granites. This event provided heat and fluids necessary for reactions between the Be- and the Cr-bearing rocks, thus enabling the formation of emeralds.

ABSTRACT: This report reviews and incorporates new elemental and isotope chemostratigraphic data for correlation of Neoproterozoic carbonate-dominated successions in South America (Argentina, Bolivia, Brazil, Paraguay and Uruguay). These thick mixed carbonate/siliciclastic successions were largely deposited in epicontinental basins or accumulated on passive margins on the edges of cratons (e.g. São Francisco, Amazonia, Rio Apa Block, Pampia and Río de la Plata paleocontinents) during extensional events related to the rifting of the Rodinia Supercontinent. From the stratigraphic point of view, these successions occur as three mega-sequences: glaciogenic, marine carbonate platform (above glaciomarine diamictites or rift successions), and dominantly continental to transitional siliciclastics. In the orogenic belts surrounding cratons, carbonate-dominated successions with important volcanoclastic/siliciclastic contribution have been, in most cases, strongly deformed. The precise ages of these successions remain a matter of debate, but recently new paleontological and geochronological data have considerably constrained depositional intervals. Here, we report high-resolution C, O, Sr, and S isotope trends measured in well-preserved sample sets and mainly use Sr and C isotopes in concert with lithostratigraphic/biostratigraphic observations to provide detailed correlations of these successions. The establishing of a high-level and definite chemostratigraphic correlation between Neoproterozoic basins in South America is the main goal of this work.

Published: October 2016

RESUMO Nascentes localizadas em locais públicos, como praças e parques, frequentemente são utilizadas pela população como fonte alternativa de água, o que pode colocar em risco a saúde pública quando não há qualidade adequada para consumo. O objetivo deste trabalho foi avaliar a água das bicas localizadas em três parques públicos da cidade de Curitiba, Paraná. O monitoramento foi realizado mensalmente por meio de de análises microbiológicas de coliformes totais (CT), Escherichia coli (EC) e bactérias heterotróficas (BH), e tomadas de pH, com coletas em triplicata durante um ano em três pontos: Parque Atuba (A), Parque Gutierrez (B) e Parque São Lourenço (C). Os resultados mostraram contaminação por CT no ponto A, em B foi observado presença em níveis elevados em todas as coletas de CT(log 2,4350±0,6730 NMP.100 mL-1), EC (log 1,0890±0,6327 NMP.100 mL-1) e BH (log 1,9170±0,6920 UFC.mL-1), não sendo observadas diferenças significativas entre os períodos de coleta (p>0,05). Foi evidenciado que nos períodos chuvosos a condição de potabilidade da água decaiu em todos os pontos avaliados, com aumento significativo na contagem de CT seguido pelo acréscimo de BH, sugerindo infiltração nas nascentes canalizadas. A presença constante de EC no ponto B sugere contaminação por esgoto, o que pode colocar em risco a saúde das pessoas que consomem a água disponível nas bicas.

RESUMO Existe a necessidade de intensificar a produtividade pecuária para alimentar a crescente população mundial. Sendo assim, objetivou-se avaliar a consorciação de pastagens Brachiaria com Estilosantes e Calopogônio sob aplicação de calagem e fosfatagem. Avaliou-se a produção de matéria orgânica e seca, densidade de perfilhos, teor de matéria seca e matéria mineral em pastagens degradadas de Brachiaria brizantha, com aplicação de calagem, fosfatagem e introdução de leguminosas. O delineamento experimental utilizado foi o inteiramente casualizado com parcelas subdividida, em que foram avaliados dois tipos de leguminosas (Estilosantes Campo Grande e Calopogônio) e três tipos de adubação (Controle, CaCo3, CaCo3 + P). A calagem e fosfatagem foram realizadas na superfície da pastagem sem incorporação. A introdução das leguminosas foi feita em plantio direto após superpastejo. As avaliações foram realizadas quando o dossel atingiu 25 cm de altura com auxílio de um quadrado de 0,25 m2. As leguminosas não diferiram para produção de matéria natural e seca das pastagens de Brachiaria brizantha (P>0,05), mas os fatores de correção e adubação (CaCo3 + P) melhoraram significativamente (P<0,05) a produção de massa das pastagens quando utilizou-se o Estilosantes Campo Grande em consorciação. Os resultados indicam a possibilidade de intensificar a produtividade pecuária usando leguminosas forrageiras, associadas com a fertilização CaCO3 + P, uma vez que são capazes de recuperar e aumentar a produtividade de pastagens cultivadas em regiões tropicais.

RESUMO Objetivou-se com este estudo avaliar o consumo e a digestibilidade aparente dos nutrientes em ovinos alimentados com sal forrageiro de faveleira (Cnidoscolus phyllacanthus) com níveis crescentes de cloreto de sódio na sua composição. Foram utilizados 25 carneiros, sem padrão racial definido, não castrados, alocados em baias individuais, distribuídos em um delineamento experimental inteiramente casualizado, com cinco tratamentos e cinco repetições. As dietas que continham 1, 3, 5 e 7% de cloreto de sódio na composição do sal forrageiro de faveleira foram oferecidas à vontade. Todos os tratamentos receberam feno de capim Tifton-85 moído como dieta basal e água à vontade. As dietas foram oferecidas duas vezes ao dia. Os níveis crescentes de cloreto de sódio no sal forrageiro de faveleira proporcionaram efeito significativo (P<0,05) sobre o consumo e a digestibilidade aparente da matéria seca, fibra em detergente neutro, proteína bruta, extrato etéreo, carboidratos não-fibrosos e nutrientes digestíveis totais, quando comparados com o tratamento controle. Recomenda-se a inclusão máxima de até 3% de cloreto de sódio na composição do sal forrageiro de faveleira, por proporcionar aumento no consumo da matéria seca. Todos os níveis testados proporcionaram aumento no consumo de proteína bruta, extrato etéreo e carboidratos não-fibrosos e também melhoraram a digestibilidade aparente de todos os parâmetros avaliados, quando comparados ao tratamento controle, contudo, o nível de 1% de inclusão de cloreto de sódio na formulação do sal forrageiro de faveleira apresentou melhor digestibilidade.

Published: October 2016

SUMMARY Recirculating water system (RAS), provide to reduce water usage and to improve the quality by nutrient recycling, so biofilters are used to reduce ammonia concentrations by oxidation to nitrate, by nitrifying-bacteria. Biological filters have been utilized to maintain acceptable water parameters to larvae and juveniles, by decreasing ammonia concentrations. The objective of this experiment was to evaluate different substrates for aquarium biofilter on performance of Nile tilapia (Oreochromis niloticus) larvae, and water quality. One-thousand-two-hundred Nile tilapia larvae (initial length = 11.6 ± 0.82 mm; body weight (BW) =189.0 ± 0.44mg) were randomly allotted into one of twenty 6-L aquariums (60 larvae aquarium-1) with five different biofilter (4 aquariums each biofilter): (1) control, no substrate; (2) seashell-and granitic crushed stone-substrate; (3) granitic crushed stone substrate; (4) quartz gravel substrate; and (5) porcelain-substrate. The conductivity, turbidity, pH, nitrate, nitrite and ammonia values indicate that seashell and granitic crushed-stone, and porcelain-substrates had greater process of biofiltration effectiveness. Water oxygen did not differ among treatments, with all levels within the benchmark for the tilapia larvae. Fishes reared in aquarium with quartz gravel-and porcelain substrate fishes had greater BW, total and standard length compared with its from other substrates. Porcelain-substrate biofilter is indicated for tilapia larviculture due to improved weight and length and water quality.

Published: October 2016

Abastract: Aim The Billings Reservoir is the largest reservoir in the metropolitan region of São Paulo and has multiple uses, including artisanal fishing. Its surroundings present intense occupation, resulting in various environmental impacts. Although the water is degraded, affecting the composition and quality of the fish, this reservoir supports artisanal fishermen who survive through this activity. This study aimed to analyze the water quality in the main sites of artisanal fishing activity, with an emphasis on the benthic community as a bioindicator. Methods Three sampling sites were selected, in which water and zoobenthos samples were collected monthly from April 2012 to March 2013. Water analyses consisted of the determination of pH, temperature, conductivity, turbidity, total dissolved solids, dissolved oxygen, total nitrogen, total phosphorus, and trophic state as well as a principal components analysis. The zoobenthos analysis consisted of determining the relative abundance and total density of taxa, the Shannon-Weaver diversity index, taxa richness, uniformity, Simpson’s dominance index, and the benthic community index and conducting a canonical correspondence analysis. The non-parametric Kruskal-Wallis test followed by the Student-Newman-Keuls test were used to investigate the existence of significant differences in the abiotic and biotic variables among the sites. Results The studied sites showed a high degree of eutrophication, with nitrogen and phosphorus totals levels above the limits defined by current Brazilian legislation. Taquacetuba (P1) showed the best environmental conditions for the development of fishing activity, with the presence of sensitive organisms (Polymitarcyidae) and higher levels of dissolved oxygen. Alvarenga (P2) had the worst water quality, with a predominance of tolerant organisms (Oligochaeta) and lower levels of dissolved oxygen. Conclusion In conclusion, the benthic community in association with abiotic metrics proved to be a useful tool as a bioindicator of environmental conditions, indicating that fishing activity at Alvarenga is not recommended due to the degradation of water quality.

Published: October 2016

This paper deals with different factors (ultrasonication, magnetic field) in determining the properties of synthesized magnetite nanoparticles. Development of technologies for creating synthetic analogues of magnetic minerals localized in human and other living organism tissues is of great importance in solving a wide range of mineralogical, medical-biological and material science problems. Magnetite is one of the physiological biominerals in living organisms, its formation being genetically determined. Magnetically ordered biogenic nanoparticles of iron oxides and hydroxides, which are biominerals, are known to realize a wide range of biological functions, including animals' orientation in space, and to play an important role in brain functioning. Migratory birds, bees, fish develop a sense of direction in space ("magnetic compass") due to the presence of magnetite, which is why this vital biomineral is of wide scientific interest. The paper describes the methods of magnetite nanoparticle synthesis using a magnetic field and ultrasound. Co-precipitation is described as one of the easiest chemical methods of synthesizing magnetic nanoparticles. Samples were synthesized by employing the method of coprecipitation of Fe3+ and Fe2+ salts in an alkaline medium involving ultrasound and magnetic fields. X-ray diffraction and magnetometry were used to study the samples. Special attention was given to the magnetic properties and determining the crystallite size of the produced mineral. The research results showed a correlation between the crystallite size and various synthesis conditions. With ultrasound applied, the size of the synthesized nanoparticles tends to be bigger as compared to that of the nanoparticles obtained without ultrasonication. It was determined that magnetization of samples increases with the increase in the size of nanoparticles. The research results are summarized in the tables and illustrations presented in the paper. The obtained data can be used for developing and improving the technologies for biogenic magnetite analogue synthesis. The paper could be of use to teachers, students, and researchers interested in biomineralogy and magnetic nanoparticle synthesis.

Authors: Turovskaya N.G.
Published: October 2016

The article deals with the research results of mental development specificity among children with certain non-epileptic paroxysmal conditions in the past medical history. Participants of the research were 107 children from 6 to 10 years old and their parents. Clinical, biographical and experimental psychological methods were used. The empirical study has showed that affect-respiratory attacks combine with the most pronounced mental functions disorders (including thinking and active attention) comparing to other non-epileptic paroxysmal conditions. Children with febrile spasms in anamnesis have disorders of certain mental functions (including thinking) with a low to medium degree and strong disorders of active attention. Vegetovisceral seizures don’t combine with thought disorders in children and are associated with a low degree disorder of active attention. Taking into consideration these findings it is possible to reveal the effective psychological ways for helping children with the pathology.

Published: October 2016

Wstęp

Porównano parametry wzrokowe potencjałów wywołanych wzorcem (pattern visual evoked potentials – PVEP) u pacjentów z ostrym zapaleniem nerwu wzrokowego.

Materiał i metody

Retrospektywną analizą objęto 49 pacjentów (53% kobiet; mediana wieku 32 lata ± 13), zgłaszających nagłe pogorszenie widzenia w jednym oku. Pacjentów podzielono na trzy grupy: pozagałkowe zapalenie nerwu wzrokowego na tle stwardnienia rozsianego; pozagałkowe zapalenie nerwu wzrokowego bez potwierdzonego tła demielinizacyjnego oraz pacjenci z obrzękiem tarczy n. II. Grupę kontrolną stanowili zdrowi, młodzi dorośli. Porównano parametry PVEP typu przejściowego (latencję i amplitudę fali P100) pomiędzy oczami z powyższych grup, a oczami grupy kontrolnej oraz pomiędzy okiem chorym i zdrowym u każdego pacjenta. Użyto testu U Manna- -Whitney’a i testu kolejności par Wilcoxona. Przyjęto poziom istotności p < 0,05.

Wyniki

Przeanalizowano wyniki PVEP 64 oczu chorych i 34 oczu zdrowych. Średnia latencja fali P100 była najdłuższa w grupie oczu z potwierdzonym MS. Nie wykazano statystycznie istotnych różnic amplitud pomiędzy oczami z grup chorych. Parametry fali P100 różniły się istotnie (p < 0,01) pomiędzy oczami chorymi a oczami grupy kontrolnej. Międzyoczne różnice latencji dla obu pobudzeń 1° i 15’ były największe w grupie chorych ze stwardnieniem rozsianym (odpowiednio p = 0,005; p = 0,026).

Wnioski

W PVEP u chorych z ostrym zapaleniem nerwu wzrokowego obserwuje się wydłużenie latencji P100 sugerujące tło demielinizacyjne, ale samo badanie nie wystarcza do rozróżnienia przyczyny leżącej u podłoża neuropatii. Wydłużona latencja fali P100 jest dokładniejszym wskaźnikiem zapalenia nerwu wzrokowego niż jej amplituda.

Published: October 2016

Wstęp

System dystrybucji leków unit dose zapewnia dostarczenie leków z apteki szpitalnej na oddział dla konkret¬nego pacjenta. Każda dawka jest oddzielnie pakowana oraz posiada etykietę z podstawowymi informacjami o leku i pacjencie, dla którego jest przeznaczona. Nie ma zatem konieczności przenoszenia, obliczania i przygotowywania leków przez pielęgniarki. Na oddziałach przechowywane są leki na okres 24-godzinnej terapii dla każdego pacjenta oraz stosowane w nagłych przypadkach.

Materiał i metody

Celem pracy było dokonanie analizy wpływu systemu dystrybucji leków unit dose na optyma¬lizację farmakoterapii. W tym celu dokonano przeglądu systematycznego dostępnego piśmiennictwa. Część metodolo-giczną wzorowano na artykule Sinnemaki i wsp. [1]. Do pracy włączono 15 publikacji, które opisywały badania trwa¬jące od miesiąca do pięciu lat, przeprowadzane od 1997 do 2011 roku. Publikacje dotyczyły błędów występujących podczas dystrybucji leków, czasu poświęcanego przez personel medyczny na aktywności związane z lekami, dokład¬ności podczas przygotowywania dawek jednostkowych oraz stabilności leków przepakowywanych.

Wyniki

Uzyskano wyniki świadczące o zminimalizowaniu odsetka błędów medycznych podczas korzystania z sys-temu dystrybucji leków unit dose oraz optymalnym czasie przygotowywania leków w tym systemie. Zarówno tech¬nicy, jak i farmaceuci wykazali się wysoką dokładnością podczas przygotowywania dawek jednostkowych. Ponadto stwierdzono, że leki przepakowywane są stabilne.

Wnioski

Zauważono konieczność przeprowadzenia kolejnych badań naukowych pogłębiających dotychczasową wiedzę na temat wpływu systemu unit dose na optymalizację kosztów farmakoterapii.

Wstęp

Zadaniem analiz statystycznych w badaniach naukowych jest wskazanie trafnych i maksymalnie wiarygod-nych wniosków w sytuacji, gdy badacz dysponuje wieloma informacjami. Zwykle można wskazać kilka różnych metod, które pozwalają to zadanie spełnić, jednak za każdym razem nasuwa się pytanie, którą z nich wybrać?

Materiał i metody

Badania zostały przeprowadzone na bazie danych, która obejmowała 3246 pacjentów przebywających na II Oddziale Kardiologii Górnośląskiego Centrum Medycznego w Katowicach-Ochojcu w latach 2003–
–2008. Analizie statystycznej poddano model, w których za zmienną zależną uznano zmienną UDAR, natomiast wyniki przeprowadzonych analiz zasugerowały dobór następujących zmiennych objaśniających: płeć, przetoczenie, PTCA, IVA, IVM, SVA, tętniak i hematokryt.

Wyniki

Czynnikami istotnie wpływającymi na wystąpienie udaru, według regresji logistycznej, są: tętniak, przetoczenie składników krwi i przebyty zabieg PTCA, natomiast według drzewa klasyfikacyjnego – tętniak i poziom hematokrytu.

Wnioski

Wyniki uzyskane za pomocą obydwu modeli statystycznych dopełniały się, a ich łączenie pozwala na uzyskanie wiarygodnych informacji, stanowiących podstawę procesu decyzyjnego.

Celem pracy jest przedstawienie hipoterapii jako skutecznej metody wspomagającej rehabilitację w sferze biopsychospołecznej osób niepełnosprawnych. Analiza opiera się na przeglądzie piśmiennictwa i dotychcza-sowych badań nad tą formą terapii.

Materiał i metody

Materiał zebrano za pomocą bibliotecznej wyszukiwarki ALEPH. Piśmiennictwo pozyskano z takich baz danych, jak PubMed i Medline.

Wyniki

Przeprowadzone dotąd badania wskazują na przydatność hipoterapii w usprawnianiu chorych na mózgowe porażenie dziecięce (MPDz). Prezentowane wyniki wskazują na istotnie lepsze efekty rehabilitacji u dzieci z MPDz poddanych skojarzonemu leczeniu metodą PNF i hipoterapii. Wykazano skuteczność hipoterapii w osiągnięciu prawidłowego środka ciężkości u dzieci z MPDz, już w trakcie jednego zabiegu, oraz prawidłowej postawy ciała. Udowodniono, że hipoterapia przyczynia się do poprawy chodu, siły motorycznej i równowagi nie tylko u chorych na MPDz, ale także u dzieci z opóźnieniem rozwojowym, z zespołem Downa oraz u osób w wieku podeszłym i po udarze. W wielu badaniach potwierdzono istotny wpływ na podniesienie poziomu poczucia własnej wartości oraz jakości i satysfakcji z życia wśród osób niepełnosprawnych.

Wnioski

Hipoterapia przynosi pozytywne efekty terapeutyczne u osób dotkniętych różnymi schorzeniami zarówno w obrębie aparatu ruchu, jak i w sferze psychicznej oraz społecznej. Jest atrakcyjną oraz skuteczną metodą wspomagania rehabilitacji.

Wstęp

Choroba nowotworowa i leczenie za pomocą leków cytostatycznych niesie ze sobą szereg negatywnych do-znań, emocji oraz skutków ubocznych. W opiece nad pacjentem onkologicznym jakość życia pozostaje w silnej zależności ze zdolnościami i możliwościami chorego do zaspokajania jego indywidualnych potrzeb.

Cel

Celem pracy była ocena jakości życia oraz ocena wpływu leczenia lekami cytostatycznymi na jakość życia chorych na nowotwory krwi.

Materiał i metody

Badania zostały przeprowadzone wśród 50 pacjentów Kliniki Hematologii, Nowotworów Krwi i Transplantacji Szpiku. W celu zbadania jakości życia osób w trakcie leczenia lekami cytostatycznymi w chorobach nowotworowych krwi posłużono się metodą sondażu diagnostycznego, z wykorzystaniem kwestionariusza ankiety własnego autorstwa oraz kwestionariusza EORTIC QLQ-C30 w wersji polskiej.

Wyniki

Z analizy materiału badawczego wynika iż:
 u prawie wszystkich badanych wystąpiły skutki uboczne przyjmowania leków cytostatycznych;
 połowa badanych oceniła jakość swojego życia ani dobrze, ani źle;
 bez względu na płeć ankietowane osoby najlepiej funkcjonują w aspekcie poznawczym.

Wnioski

1. Choroba i leczenie wywarły większy negatywny wpływ na życie intymne mężczyzn niż kobiet.
2. Kobiety istotnie niżej oceniły jakości życia w aspekcie funkcjonowania fizycznego, natomiast mężczyźni istotnie gorzej ocenili jakości życia w skali objawów takich, jak ból, duszność oraz zaparcia.
3. Zmęczenie, jako objaw choroby, było najczęściej zgłaszaną dolegliwością wśród ankietowanych.
4. Czynniki demograficzne, tj. wiek, stan cywilny, aktywność zawodowa, poziom wykształcenia oraz miejsce zamieszkania, korelowały z wybranymi domenami jakości życia.
5. Ogólna ocena jakości życia pacjentów była obniżona średnio o 50%.

Authors: Zhou Xiang , Zhang Pengyi , Wang Jun
Published: October 2016

Purpose

This research aims to identify product search tasks in online shopping and analyze the characteristics of consumer multi-tasking search sessions.

Design/methodology/approach

The experimental dataset contains 8,949 queries of 582 users from 3,483 search sessions. A sequential comparison of the Jaccard similarity coefficient between two adjacent search queries and hierarchical clustering of queries is used to identify search tasks.

Findings

(1) Users issued a similar number of queries (1.43 to 1.47) with similar lengths (7.3–7.6 characters) per task in mono-tasking and multi-tasking sessions, and (2) Users spent more time on average in sessions with more tasks, but spent less time for each task when the number of tasks increased in a session.

Research limitations

The task identification method that relies only on query terms does not completely reflect the complex nature of consumer shopping behavior.

Practical implications

These results provide an exploratory understanding of the relationships among multiple shopping tasks, and can be useful for product recommendation and shopping task prediction.

Originality/value

The originality of this research is its use of query clustering with online shopping task identification and analysis, and the analysis of product search session characteristics.
China's Roadmap to Global Trade and Market Share Dominance
Authors: Mafukata Mavhungu Abel
Published: October 2016

This paper re-construct the roadmap adopted by China to dominate global trade and market share space with reference to SSA. Specifically, this paper characterises the nature of China's practice of political economy where the country does business. Literature was reviewed to collect data used in the re-construction of the model. This paper found that indeed China has a clearly set roadmap (figure 1) for its global trade and market share space acquisition and dominance. China's dominance of the economic and market space in SSA has an assortment of intertwined complexities for the region. Sub-Saharan Africa needs to excercise caution on China because signs are there already that China would not be any different from the Western economies who had exploited the region for decades for their own gain, not the region's gain.
A 2D electrical resistivity tomography survey of a vineyard plot of the Gaillac appellation (France): interpretation with respect to possible implications on vine water supply

Published: October 2016

Aims: The aim of this 2D electrical resistivity tomography (ERT) survey performed on a vineyard plot of the Gaillac appellation was to investigate spatial and temporal variations in subsurface water supply in relation with pedo-geological and morphological features.

Methods and results: The ERT surveys were carried out under two contrasted - dry and humid - climatic conditions. All the resistivity profiles showed the superposition of two layers: a lower layer characterized by very low resistivity values (< 40 Ω.m) corresponding to a marly molassic subsoil overlaid by an upper layer characterized by moderate to high resistivity values (300 Ω.m to 1500 Ω.m) corresponding to a silty-sandy and gravely-pebbly soil sequence. The resistivity values of the molassic subsoil stayed very low independently of water supply conditions whereas those of the soil sequence decreased by a factor 2 (300/750 Ω.m versus 750/1500 Ω.m) when the plot was close to field capacity.

Conclusion: The ERT results coupled with pedological and morphological data strongly suggest that the water flow is preferentially restricted at the molassic subsoil/soil sequence interface, short-lived and of low amplitude.

Significance and impact of the study: Consequently, the water supply regime, which points out a potential risk of drought stress for vine crops, implies a minimization strategy when choosing vegetal material and viticultural management operations
Predicting the occurrence of iron chlorosis in grapevine with tests based on soil iron forms
Authors: Díaz de la Torre Isabel , Del Campillo María Del Carmen , Barrón Vidal , Torrent José
Published: October 2016

Aims: Iron deficiency symptoms (leaf chlorosis and depressed growth) are common in grapevine growing on calcareous soils. The objective of this study was to investigate the relationships between these symptoms and the properties of Spanish vineyard soils.

Methods and results: Soils from thirty vineyards with leaf chlorosis were used to pot '110 Richter' rootstock for three seasons. Mean leaf chlorophyll concentration, as measured via SPAD, was positively correlated with the soil content in poorly crystalline Fe oxides, as estimated by extraction with various reagents, and negatively correlated with the contents in calcium carbonate equivalent and active lime. Iron deficiency affected plant growth but none of the measured growth variables was correlated with soil properties. The relationships between SPAD and acid ammonium oxalate-, citrate/ascorbateand unbuffered hydroxylamine-extractable Fe conformed to the linear-plateau model, from which clear-cut critical levels (345, 425 and 8 mg kg-1, respectively) could be established. This was not possible with tests based on the alkalinity properties (e.g. the calcite ion activity product), the IPC (« Indice du pouvoir chlorosant »), and the DTPA-extractable Fe test, which generally exhibited a poor predictive value.

Conclusion: Tests based on reagents capable of extracting, in part or quantitatively, the most reactive forms of soil Fe were useful to estimate the risk of Fe chlorosis in grapevine. Acid ammonium oxalate, citrate/ascorbate and unbuffered hydroxylamine were the best extractants for this purpose.

Significance and impact of study: This study has shown the limited usefulness of tests based on the contents and reactivity of the soil carbonate to predict the occurrence of Fe chlorosis in grapevine; tests capable of estimating the contents of the labile soil Fe forms constitute the best alternative.

Authors: Salameh Dominique , Brandam Cédric , Rizk Toufic , Lteif Roger , Strehaiano Pierre
Published: October 2016

Aims: This paper presents a rapid chromatographic method to monitor the concentration of p-coumaric acid in wine and in bioconversion studies.

Methods and results: RP-HPLC method was validated in synthetic wine medium and in natural red wine. Mobile phase composition was water 77%, acetonitrile 23%. Formic acid was added to control pH at 3.5. The flow was 0.7 mL/min and the temperature 30 °C. The detection was done using UV at 305 nm. The linearity range was validated between 0.5 and 15 mg/L. The resolution was respectively 5.35 and 2.99. The detection and quantification limits were 0.01 mg/L and 0.04 mg/L. This method was used to study p-coumaric acid bioconversion into 4-ethylphenol and 4-vinylphenol, and to study this acid adsorption in enological conditions.

Conclusions: This paper presented a simple HPLC method to monitor the concentration of p-coumaric acid in synthetic media and natural wine. It was used to study the p-coumaric acid bioconversion rates and mechanism.

Significance and impact of the study: This method is useful to monitor p-coumaric acid concentration, which helps to predict amounts of 4-ethylphenol or 4-vinylphenol that can be produced in wine. This method can be helpful to control undesirable phenolic flavors potential in wine.
First description of the occurrence of the leafhopper Phlogotettix cyclops in a Bordeaux vineyard
Authors: Chuche Julien , Danet Jean-Luc , Thiéry Denis
Published: October 2016

Aim: The aim of this study was to investigate the occurrence of new leafhopper species, which could be potential vectors of plant pathogens, in the vineyards of the Bordeaux region.

Methods and results: Grapevine woody canes were collected in a vineyard without insecticide treatments during the winter of 2008. The unidentified leafhoppers that hatched from the dormant canes were collected and individually reared to adults on grapevine cuttings in a cage. Species identification was performed with males. The survey led to the detection of a new leafhopper species in Bordeaux vineyards, Phlogotettix cyclops.

Conclusions: P. cyclops is an invasive species whose larvae look like the ones of Scaphoideus titanus. The presence of this species in a Bordeaux vineyard suggests that it is spreading northward across the southwest of France. Furthermore, this leafhopper could become a vine pest in the future.

Significance and impact of the study: This study provided useful information for viticultural researchers and professionals, particularly in France, but also elsewhere in Europe.
Efficiency of different strategies for the control of grey mold on grapes including gibberellic acid (Gibb3), leaf removal and/or botrycide treatments
Authors: Evers Danièle , Molitor Daniel , Rothmeier Melanie , Behr Marc , Fischer Serge , Hoffmann Lucien
Published: October 2016

Aim: The present work evaluated different strategies for the control of grey mold, caused by Botrytis cinerea, on wine grapes, including the use of the plant growth regulator Gibb3, leaf removal and/or botryticide treatments. The efficiency of the different control strategies (disease incidence and severity, yield) as well as the effect on the cluster structure was investigated.

Methods and results: The trials were conducted in commercial vineyards in the Moselle Valley (Luxembourg) between the years 2007 and 2009, on the Pinot gris, Pinot blanc and Pinot noir grape varieties. The untreated control (T1) was compared to the following treatments : (T2) Gibb3, (T3) Gibb3 combined with leaf removal in the cluster zone after bloom, (T4) leaf removal after bloom combined with two times botryticides and (T5) Gibb3 combined with two times botryticides. The combination of Gibb3 with leaf removal or botryticide applications led to an efficiency level in grey mold reduction of around 60% and a decrease in cluster density when compared to the control. Moreover, we showed that the progression of grey mold disease was slowed down by the three treatments T3, T4 and T5.

Conclusions: Gibberellic acid applied at full bloom as stand-alone treatment did not reduce in a significant way the compactness of the grape clusters and the impact on grey mold development was low. For a significant decrease of disease severity, gibberellic acid had to be combined with an additional measure, such as leaf removal or the use of botryticides. Based on its positive effect on cluster structure and microclimate, leaf removal can be recommended as a basic measure that can be further combined with an application of botryticides or gibberellic acid.

Significance and impact of the study: All the tested strategies combining two measures have shown their potential to prolong the ripening period and therewith to improve wine quality. Moreover, the combined use of gibberellic acid and leaf removal represents a sustainable strategy for integrated viticulture due to its reduced input of organic-synthetic pesticides into the environment.
