A Study on the Preparation of Rare Earth Oxide Powder for Rare Earth Precipitates Recovered from Spent Ni-MH Batteries
Authors: Kim Dae-Weon , Ahn Nak-Kyoon , Shim Hyun-Woo , Park Kyung-Soo , Choi Hee-Lack
Published: July 2018

We report a method for preparing rare earth oxides (RexOy) from the recycling process for spent Ni-metal hydride (Ni-MH) batteries. This process first involves a leaching of spent Ni-MH powders with sulfuric acid at 90°C, resulting in rare earth precipitates (i.e., NaRE(SO4)2·H2O, RE = La, Ce, Nd), which are converted into rare earth oxides via two different approaches: i) simple heat treatment in air, and ii) metathesis reaction with NaOH at 70°C. Not only the morphological features but also the crystallographic structures of all products are systematically investigated using field-emission scanning electron microscopy (FESEM) and X-ray diffraction (XRD); their thermal behaviors are also analyzed. In particular, XRD results show that some of the rare earth precipitates are converted into oxide form (such as La2O3, Ce2O3, and Nd2O3) with heat treatment at 1200°C; however, secondary peaks are also observed. On the other hand, rare earth oxides, RexOy can be successfully obtained after metathesis of rare earth precipitates, followed by heat treatment at 1000°C in air, along with a change of crystallographic structures, i.e., NaRE(SO4)2·H2O → RE(OH)3 →RexOy.

In this study, we investigate the deformation behavior of Hf44.5Cu27Ni13.5Nb5Al10 metallic glass powder under repeated compressive strain during mechanical milling. High-density (11.0 g/cc) Hf-based metallic glass powders are prepared using a gas atomization process. The relationship between the mechanical alloying time and microstructural change under phase transformation is evaluated for crystallization of the amorphous phase. Planetary mechanical milling is performed for 0, 40, or 90 h at 100 rpm. The amorphous structure of the Hf-based metallic glass powders during mechanical milling is analyzed using differential scanning calorimetry (DSC) and X-ray diffraction (XRD). Microstructural analysis of the Hf-based metallic glass powder deformed using mechanical milling reveals a layered structure with vein patterns at the fracture surface, which is observed in the fracture of bulk metallic glasses. We also study the crystallization behavior and the phase and microstructure transformations under isothermal heat treatment of the Hf-based metallic glass.
Recent Progress in Flexible Energy Harvesting Devices based on Piezoelectric Nanomaterials
Authors: Park Kwi-Il
Published: July 2018

Recent developments in the field of energy harvesting technology that convert ambient energy resources into electricity enable the use of self-powered energy systems in wearable and portable electronic devices without the need for additional external power sources. In particular, piezoelectric-effect-based flexible energy harvesters have drawn much attention because they can guarantee power generation from ubiquitous mechanical and vibrational movements. In response to demand for sustainable, permanent, and remote use of real-life personal electronics, many research groups have investigated flexible piezoelectric energy harvesters (f-PEHs) that employ nanoscaled piezoelectric materials such as nanowires, nanoparticles, nanofibers, and nanotubes. In those attempts, they have proven the feasibility of energy harvesting from tiny periodic mechanical deformations and energy utilization of f-PEH in commercial electronic devices. This review paper provides a brief overview of f-PEH devices based on piezoelectric nanomaterials and summarizes the development history, output performance, and applications.
On Special Fiber Rings of Modules
Authors: Miranda-Neto Cleto B.
Published: July 2018

We prove results concerning the multiplicity as well as the Cohen–Macaulay and Gorenstein properties of the special fiber ring $\mathscr{F}(E)$ of a finitely generated $R$-module $E\subsetneq R^{e}$ over a Noetherian local ring $R$ with infinite residue field. Assuming that $R$ is Cohen–Macaulay of dimension 1 and that $E$ has finite colength in $R^{e}$, our main result establishes an asymptotic length formula for the multiplicity of $\mathscr{F}(E)$, which, in addition to being of independent interest, allows us to derive a Cohen–Macaulayness criterion and to detect a curious relation to the Buchsbaum–Rim multiplicity of $E$ in this setting. Further, we provide a Gorensteinness characterization for $\mathscr{F}(E)$ in the more general situation where $R$ is Cohen–Macaulay of arbitrary dimension and $E$ is not necessarily of finite colength, and we notice a constraint in terms of the second analytic deviation of the module $E$ if its reduction number is at least three.
Examples of Non-finitely Generated Cox Rings
Authors: González José Luis , Karu Kalle
Published: July 2018

We bring examples of toric varieties blown up at a point in the torus that do not have finitely generated Cox rings. These examples are generalizations of our earlier work, where toric surfaces of Picard number 1 were studied. In this article we consider toric varieties of higher Picard number and higher dimension. In particular, we bring examples of weighted projective 3-spaces blown up at a point that do not have finitely generated Cox rings.

Published: July 2018

We used whole-genome sequencing to investigate a tuberculosis outbreak involving U.S.-born persons in the prison system and both U.S.- and foreign-born persons in the community in Florida over a 7-year period (2009–2015). Genotyping by spacer oligonucleotide typing and 24-locus mycobacterial interspersed repetitive unit-variable number tandem repeat suggested that the outbreak might be clonal in origin. However, contact tracing could not link the two populations. Through a multidisciplinary approach, we showed that the cluster involved distinct bacterial transmission networks segregated by country of birth. The source strain is of foreign origin and circulated in the local Florida community for more than 20 years before introduction into the prison system. We also identified novel transmission links involving foreign and U.S.-born cases not discovered during contact investigation. Our data highlight the potential for spread of strains originating from outside the United States into U.S. “high-risk” populations, such as prisoners, with subsequent movement back to the general community.
Non-Respiratory and Non-Diarrheal Causes of Acute Febrile Illnesses in Children Requiring Hospitalization in a Tertiary Care Hospital in North India: A Prospective Study

Published: July 2018

Acute febrile illnesses (AFIs) in children from the developing world can have varying etiologies. Awareness of local epidemiology helps in prioritizing investigations and empiric treatment. This prospective study was carried out in a tertiary care center in North India, aiming to determine the burden, etiology, and outcome of AFI other than pneumonia and diarrhea in hospitalized children. A total of 613 consecutive children aged 3 months to 12 years with febrile illness of < 7 days during four selected months of 2014 representing different seasons were screened for eligibility. Those with acute respiratory diseases (N = 175, 28.5%) and diarrheal illness (N = 46, 7.5%) were excluded and 217 children were enrolled. Mean (standard deviation) age was 4.8 (3.4) years. Nearly half (N = 91, 41.9%) presented in post-monsoon season. Diagnosis could be established in 187 (86.2%) children. Acute central nervous system infections were the most common (N = 54, 24.8%). Among specific infections, scrub typhus was the most frequent (N = 23, 10.5%) followed by malaria (N = 14, 6.4%), typhoid (N = 14, 6.5%), and viral hepatitis (N = 13, 6.0%). Blood culture had a low (6.5%) yield; Salmonella typhi (N = 6) and Staphylococcus aureus (N = 5) were the common isolates. Serological tests were helpful in 50 (23%) cases. In multivariate analysis, hepatomegaly and/or splenomegaly independently predicted scrub typhus. Mortality rate was 10.1%. We conclude that AFI other than pneumonia and diarrhea are a significant burden and follow a seasonal trend. Scrub typhus has emerged as an important etiology of childhood AFIs in northern India. Periodic review of regional epidemiology will help in understanding the changing pattern of infectious diseases.

In rural areas in Morocco, diagnosing cutaneous leishmaniasis (CL) can be challenging. We evaluated the accuracy of a rapid diagnostic test (RDT) based on antigen detection, CL Detect Rapid Test™ (Inbios International Inc., Seattle, WA), in this setting. We consecutively recruited patients with new skin ulcers in nine primary health centers. We took a dental broach sample for the RDT and two other tissue samples by scraping the border and center of the lesion with a scalpel and smearing it on a slide. We duplicated each smear by pressing a clean slide against it and processed the slides by microscopy, polymerase chain reaction (PCR) internal transcribed spacer 1, and kDNA minicircle PCR. In a subgroup with positive PCR, the Leishmania species was identified using PCR-restriction fragment length polymorphism and PCR-sequencing of hsp70 genes. A participant with positive microscopy and/or PCR was considered a confirmed CL case. We computed sensitivity (Se) and specificity (Sp) of the RDT compared with this reference standard (ClinicalTrials.gov registration: NCT02979002). Between December 2016 and July 2017, we included 219 patients, 50% of them were under 18 years old. Rapid diagnostic test Se was 68% [95% confidence interval (CI): 61–74], Sp 94% [95% CI: 91–97], positive predictive value 95% [95% CI: 92–98], and negative predictive value 64% [95% CI: 58–70]. Despite its low Se, this novel RDT is a useful addition to clinical management of CL in Morocco, especially in isolated localities. Rapid diagnostic test–positive lesions can be treated as CL; but when RDT negative, microscopy should be done in a second step. The Se of the RDT can probably be optimized by improving the sampling procedure.

Flaviviruses such as Zika, dengue, and yellow fever cause epidemics throughout the tropics and account for substantial global morbidity and mortality. Although malaria and other vector-borne diseases have long been appreciated in Africa, flavivirus epidemiology is incompletely understood. Despite the existence of an effective vaccine, yellow fever continues to cause outbreaks and deaths, including at least 42 fatalities in the Democratic Republic of the Congo (DRC) in 2016. Here, we leveraged biospecimens collected as part of the nationally representative 2013–2014 Demographic and Health Survey in the DRC to examine serological evidence of flavivirus infection or vaccination in children aged 6 months to 5 years. Even in this young stratum of the Congolese population, we find evidence of infection by dengue and Zika viruses based on results from enzyme-linked immunosorbent assay and neutralization assay. Surprisingly, there was remarkable discordance between reported yellow fever vaccination status and results of serological assays. The estimated seroprevalences of neutralizing antibodies against each virus are yellow fever, 6.0% (95% confidence interval [CI] = 4.6–7.5%); dengue, 0.4% (0.1–0.9%); and Zika, 0.1% (0.0–0.5%). These results merit targeted, prospective studies to assess effectiveness of yellow fever vaccination programs, determine flavivirus seroprevalence across a broader age range, and investigate how these emerging diseases contribute to the burden of acute febrile illness in the DRC.

Abstract. Gas-phase atmospheric concentrations of PAN, PPN, and MPAN were measured at the ground using GC-ECD during the SOAS 2013 campaign (1 June to 15 July 2013) in Centerville, Alabama in order to study biosphere-atmosphere interactions. Average levels of PAN, PPN and MPAN were 169, 5, and 9 pptv respectively, and the sum accounts for an average of 15 % of NOy during the daytime (10 am to 4 pm local time). Higher concentrations were seen on average in air that came to the site from the urban NOx sources to the north. PAN levels were the lowest observed in ground measurements over the past two decades in the Southeastern U.S. Analysis of PAN/NOx indicates PAN production in this region was sensitive to NOx. A multiple regression analysis indicates that biogenic VOCs account for 66 % of PAN formation in this region of the Southeastern U.S. Comparison of this value with a 0-D model simulation of peroxyacetyl radical production indicates that at least 50 % of PAN formation is due to isoprene oxidation. MPAN has a statistical correlation with isoprene hydroxynitrates (IN) with an average MPANppb/INppb ratio of 0.3. Organic aerosol mass increases with gas-phase MPAN and IN concentrations, but the mass of organic nitrates in particles is largely insensitive to MPAN. Isoprene and PAN play a significant role in the atmospheric chemistry in the Southeastern United States.
Determining the drivers for snow gliding
Authors: Fromm Reinhard , Baumgärtner Sonja , Leitinger Georg , Tasser Erich , Höller Peter
Published: July 2018

Abstract. Snow gliding is a key factor for snow-glide avalanche
formation and soil erosion. This study considers atmospheric and snow
variables, vegetation characteristics, and soil properties and determines
their relevance for snow gliding at a test site (Wildkogel, Upper Pinzgau,
Austria) during winter 2014/2015. The time-dependent data were collected at a
high temporal resolution. In addition to conventional sensors, a “snow melt
analyzer” was used. The analysis shows that the soil temperature 10 cm below the surface, the
phytomass of mosses, the liquid water content in the snowpack, and the
static friction coefficient of the glide shoes had significant influence on
snow gliding during the whole winter. In the first period (October to
January) the soil moisture at the surface and 1.5 cm below the surface and
the length of the slope uphill of the glide shoes affected the snow gliding,
too. In the second period (February to May) the soil temperature at the
surface, the soil moisture 10 cm below the surface, and the slope angle had
additional influence on snow gliding. The role of the vegetation in the snow-glide process is determined by the
influence on the static friction coefficient caused by its composition and
characteristics and by moss-rich and short-stemmed canopies being seemingly
more interconnected with the snowpack. In addition to the soil and snow properties, the topography and the
vegetation characteristics, further investigations may be focused on the
freezing and melting processes in the uppermost soil layers and at the soil surface.
Geophysical and Geodetical Investigation of A Landslide Area (Koyulhisar-Sivas, Turkey)
Authors: Özel Sevda , Över Demet , Hastaoğlu Kemal Özgür
Published: July 2018

Abstract. This study includes geophysical studies carried out in the last section in the close south of Koyulhisar (Sivas) landslide site. Additionally, the study area is in the most active location where landslide's displacement amount is the highest. The landslide site basically has been examined geophysics (SRT, GPR) and geodesic (GNSS) methods. According to the geophysical results, within ~ 20 m of investigation depth, layers with the average seismic P-wave velocities (VP) of 0.30, 1.00 and 2.00 km/s have been identified. It has been understood that the thickness of the first two layers of these layers from top to the bottom is approximately 3 and 6.5 m, and the last layer with Vp > 2.0 km/s is the bedrock. Furthermore, it has been understood that the depth of the sliding surface which is the upper limit of the bedrock varies between ~ 7–10 m, there are loose units on the sliding surface, the type of sliding is planar sliding, and the direction of sliding is S–SE, the tilt of the layer has the same direction with topography, is SE-oriented and mostly bigger than 50. It was understood that the deformations in the landslide mass were occured from the geological unit, the layer or topography slope and precipitation and the landslide activity can continue in the study area. Thus, it has proven that precipitation and deformations within the layer are effective in triggering the landslide by the geodetic (IDH) observations, and it is understood that they were compatible with the geophysical results. Therefore, the study area contains the risk and the natural hazards, and these threatens the settlement area and the buldings and other constructions there.
Numerical and remote techniques for operational beach management under storm group forcing

Published: July 2018

Abstract. The morphodynamic response of a microtidal beach under a storm group is analyzed, and the effects of each individual event inferred from a numerical model, in situ measurements and video imaging. The first storm, with moderate conditions (Hs ~ 1 m during 6 h), eroded the aerial beach and generated a submerged sandbar in the breaking zone. The bar is further directed offshore during the more energetic second event (Hs = 3.5 m and 53 h). The third storm, similar to the first one, hardly affected the beach morphology, which stresses the importance of the beach configuration previous to a storm. The volume of sand mobilized during the storm group was around 17.65 m3/m. During the following months, which were characterized by mild wave conditions, the dry beach recovered half of the volume of sand that was transported offshore during the storm group (~ 9.27 m3/m). The analysis of beach evolution shows two different characteristic time scales for the erosion and the recovery processes associated with storm and mild conditions respectively. Besides, the response depends largely on the previous beach morphological state. The work also stresses the importance of using different tools (video-monitoring, modeling and field campaign) to analyze beach morphodynamics.
Les Idées sociopolitiques de Casanova sur la France du dix-huitième siècle — selon l’édition de 1880 de ses Mémoires
Authors: Messina Luisa
Published: July 2018

Casanova est pratiquement esthète dans son appréciation des personnes, mais il les évalue aussi par rapport à leur abord, leur politesse sociale ou savoir vivre. Entre ses trois visites, la société change. Outre ses amis disparus, le voyageur n’a plus la joie de la conquête. Le Paris qu’il connaissait s’est transformé en une sorte de labyrinthe incompréhensible. Voulant aller de Saint-Eustache à la rue Saint-honoré, il s’égare dès qu’il ne trouve plus l’Hôtel de Soissons. Il n’a plus de succès au jeu, en amour ni en diplomatie. Louis XV dont les excès sexuels rappellent la débauche juvénile de Casanova est bien loin. Le vénitien conclut son observation en admirant le défunt Louis XV tandis que son jugement sur Louis XVI est féroce, parce que le voyageur attribue les maux à la faiblesse du dernier roi des Bourbons, qui aurait sauvé la France des horreurs révolutionnaires. La France n’est plus à l’image de sa seconde patrie.
Une théorie du libelle : Linguet et l’émergence de l’idée de littérature
Authors: Boixière Thibault
Published: July 2018

Libelle et diffamation sont intimement liés. D’ailleurs, dans la langue anglaise, diffamation se dit notamment libel, et diffamatoire libellous. En français québécois, on dit encore d’un texte qu’il est libelleux. Dans La Parole pamphlétaire, Marc Angenot explique ce glissement sémantique : « Dès le XIVe siècle, il va être fréquemment associé à ‘diffamatoire’, libellus diffamatorius. Par brachylogie, l’adjectif disparaissant, il vaut pour ‘petit livre d’injure’ et devient synonyme de pamphlet dans une de ses acceptions » (p. 314). Le libelle diffamatoire est devenu libelle tout court, en français, et diffamation en anglais. A l’heure actuelle, le terme libelle possède toujours un sens dans le droit canonique : il désigne « tout acte signifié par écrit ». En somme, si le libelle peut appartenir à la fois au vocabulaire juridique et littéraire, c’est précisément du fait de sa matérialité, un « petit livre ». Si le XVIIIe siècle abonde en figure d’avocat-écrivain — pensons à Fontenelle ou Beaumarchais — Linguet en est peut-être l’incarnation la plus frappante. Outre qu’il est l’un des libellistes les plus célèbres et féroces du siècle, avec Fréron et La Beaumelle, il est le premier à avoir entrepris un art poétique du libelle ; l’œuvre de Linguet semble constituer le corps où se joue quelque chose comme le creusement d’une définition de la littérature dans son commerce, parfois conflictuel, avec le champ juridique.
Lire pour la première fois. La découverte de la littérature dans quelques fictions pédagogiques de la deuxième moitié du XVIIIe siècle (Rousseau, Madame de Genlis)
Authors: Zagamé Antonia
Published: July 2018

« Lire pour la première fois » : Les fictions pédagogiques de Rousseau et Madame de Genlis prévoient une rencontre avec la littérature toute autre que celle envisagée selon le schéma d’éducation traditionnel, qui privilégie à cette époque un apprentissage littéraire « précoce ». Dans l’Emile (1761) et Adèle et Théodore (1782), la découverte des œuvres littéraires, entièrement orchestrée par le pédagogue, est en effet retardée dans le temps. Emile lit son premier livre, Robinson Crusoé, à douze ans, avant les Vies parallèles de Plutarque et les Fables de La Fontaine à dix-huit ans. Mais ces trois textes sont envisagés avant tout pour leur contenu didactique et Emile ne découvrira véritablement les différents genres des Belles-lettres qu’à vingt ans. Quant à Madame de Genlis, elle imagine un parcours de lecture progressif permettant de conduire la jeune Adèle d’ouvrages conçus pour la jeunesse, à la découverte des chefs-d’œuvre de la littérature à partir de seize ans, une fois nourrie de la lecture d’auteurs de second ordre. La fiction permet ainsi aux deux écrivains d’imaginer ce que serait le regard d’un jeune homme ou d’une jeune femme privés des principaux ouvrages des Belles-Lettres jusqu’à un âge avancé, et les découvrant au moment où leur intelligence et leur sensibilité sont parvenues à pleine maturité. Rousseau envisage un système d’imprégnation spontanée de l’objet culturel pour un être qui va changer l’ordre social, tandis que Genlis procède par gradation pour une femme qui s’intègrera à l’ordre social.

Territorios militares en Hispania: nuevas perspectivas
Authors: Morillo Cerdán Ángel , Durán Cabello Rosalía María
Published: July 2018

Los documentos epigráficos relativos a los límites de distritos militares no suelen ser muy habituales, aunque el conjunto procedente del norte de la Península Ibérica es el más numeroso de todo el Imperio. Se conocen cerca de 30 inscripciones relativas a la legio IIII Macedonica, a la legio X gemina y a la cohors IV Gallorum. Presentaremos en este trabajo un estado de la investigación sobre los territorios militares en Hispania. Es preciso definir los rasgos propios de estos distritos que circundan los campamentos romanos, que se encuentran bajo el control directo del ejército desde el punto de vista económico y jurisdiccional. Las excavaciones realizadas durante los años 2000-2001 al sureste de la ciudad de León, al otro lado del río Torío y junto al actual barrio de Puente Castro nos han permitido identificar una nueva aglomeración secundaria o vicus, denominado Ad Legionem, surgido a 2,2 km de distancia del campamento legionario de la legio VII gemina y en estrecha relación de dependencia respecto a éste. A partir de la existencia de este vicus militar satélite podemos plantear que también en el caso de Hispania se verifica la existencia de la leuga, franja de territorio de un radio de 1,5 millas (2,2 km), bajo jurisdicción militar.

First, study examined the prediction power of the political skills address perceived organizational support (POS), organizational citizenship behavior (OCB), job satisfaction and intention to quit; bottom-line to find the moderation effect of psychological empowerment on prescribed relationship. It is also evident that employees, who are mentally strong, psychologically empowered and dedicated towards the organization, have degree to influence someone, having self-efficacy and are self-determined. Using simple random sampling methodology, data were collected from nine different public and private corporate sector of Lahore. Study utilized sample of 310 employees.  The study revealed that political skills has positive effects on perceived organizational support (POS), organizational citizenship behaviour (OCB), job satisfaction; a negative effect on intention to quit, results revealed by regression technique. The presence of positive political skills seemed to urge employees to perform well at the job, moderation effect were tested by Preacher, Rucker, & Hayes (2007) moderation process. Study finds the moderation support of psychological empowerment on the relationship of political skills toward perceived organizational support (POS), organizational citizenship behavior (OCB), job satisfaction; however, study could not find moderation effect on political skills toward intention to quit. Results of the study highlighted the importance of inculcating a positive work environment, which complements by positive political skills, and will be discussed. Limitations of study, future research directions and results underscore the importance of considering the direction of positive political skills.

EFECTOS DE LA IRREGULARIDAD VERTICAL DE PISO BLANDO SOBRE LA RESPUESTA NO-LINEAL DE ESTRUCTURAS APORTICADAS
Authors: Janampa Ochoa Jorge , Fernandez Davila Victor I.
Published: July 2018

En sismos pasados ocurridos en el Perú y el mundo se ha observado que la irregularidad vertical debido al fenómeno de piso blando en estructuras de edificios representa una grave amenaza para su integridad y estabilidad. Prevenir el colapso para preservar la vida de los ocupantes de una estructura es uno de los objetivos principales en todas las normas de diseño sismorresistentes en el mundo. Por ello, conocer a partir de que alturas existe esta irregularidad constituye un dato crítico para determinar la posibilidad de colapso por piso blando. Este dato es importante tanto para el diseño de nuevas estructuras como para la evaluación y rehabilitación de estructuras existentes. Se revisaron varios códigos para conocer la definición de la irregularidad vertical de piso blando y se presenta un resumen de las especificaciones de estos códigos. Se analizaron modelos de edificios aporticados de tres, cinco, nueve y quince pisos, con dos vanos en ambas direcciones. La luz de los vanos es de 5 m, la altura típica es de 3 m y la altura del primer piso varía desde 3 m hasta 9 m. Tales modelos fueron diseñados de acuerdo a las recomendaciones del Reglamento Nacional de Edificaciones del Perú [11]. Con fines de comparación, se desarrolla un modelo patrón de tipología regular, tanto en planta como en elevación, y los casos que representan las estructuras irregulares se definen mediante la modificación de la distribución vertical de la rigidez, incrementando la altura del primer piso del modelo patrón hasta identificar los elementos estructurales más débiles que fallen primero.

En todos los edificios estudiados de tres, cinco, nueve y quince pisos, para la altura del primer piso que varía de tres hasta menos de siete metros la distorsión está comprendida entre el nivel de desempeño de ocupación inmediata (IO) y seguridad de vida (LS). Para la altura del primer piso que varía de siete hasta nueve metros la distorsión está comprendida entre el nivel de desempeño de seguridad de vida (LS) y prevención del colapso (CP). Por consiguiente se puede concluir que la altura máxima en un entrepiso de un edificio aporticado para que no se produzca piso blando y que se considere aceptable debe ser menor de siete metros. Esto quiere decir una relación de altura (altura típica / altura de primer piso) hasta 42%, es un límite aceptable. Esto es mucho menor que el porcentaje que declara la irregularidad debido al piso blando en la norma peruana E.030(2003) 75% y E.030 (2016) 60%, lo que implica que la norma sísmica peruana E.030 es seguro, de alguna manera conservadora.

Esse trabalho tem como objetivo fazer um estudo das trajetórias dos desembargadores do Tribunal de Justiça do Paraná entre 1891 e 1981 e, desse modo, analisar o processo de institucionalizaçãodos desembargadores. Temos como hipótese que o período de entrada no TJ-PR se relaciona ao tipo de carreira profissional, isso é, os agentes que se tornaram desembargadores no final do período estudado tenderam a possuir uma trajetória mais endógena no Poder Judiciário do que aqueles que entraram inicialmente. Os dados utilizados para tal fim foram coletados do livro “História do Poder Judiciário no Paraná” (1982), das Secretarias de Estado e Cultura e do Esporte, que contém informações de todos os 110 desembargadores que pertenceram ao período analisado. As variáveis utilizadas emnossa análise consistem em (a) tempo investido na carreira jurídica até o cargo de desembargador, (b) idade em que iniciou a carreira e que ingressou no TJ/PR, (c) instituição na qual se bacharelou, e (d) cidade e estado em que ocupou cargos públicos.

As discussões acerca do processo de desindustrialização no Brasil tem se tornado recorrente e os resultados ensejam muita controvérsia. Um fator que contribui para isso é a heterogeneidade dos dados para o Brasil e dados muito agregados de comércio externo. Neste sentido, os estudos com escopo regional parecem uma estratégia para tal análise. Assim, este estudo tem por objetivo aclarar a relação entre câmbio e renda externa sobre a Balança Comercial – BC – de bens básicos no Paraná, para o período de 2000 a 2015. Foram utilizadas ferramentas de séries temporais – modelo VECM e elasticidades de transmissão de curto e longo prazo – para tal. Os resultados sinalizam que a BC dos produtos básicos no estado é elástica tanto em relação ao câmbio quanto à renda externa – responde mais que proporcionalmente – o que destaca que crescimento da renda externa acelerado e desvalorizações cambiais levam a uma intensificação nas exportações de produtos básicos.

Multi-Disciplinary Rounding (MDR) is a leading practice and a promising process innovation that seeks to enhance both patient experiences and healthcare outcomes for hospitals. It requires multiple hospital staff involved in patientcare visiting patients as a team at their bedside, so that they can address various issues related to patientcare and care transition and answer any patient questions. This paper discusses the implementation of two different models of patient engagement through MDR to gain input from patients while they are still in the hospital, as opposed to relying on patient satisfaction data, so that hospitals can alter their strategies to educate patients on care plans and help empower them to self-manage their care post-discharge. The MDR is implemented as a process innovation at a comprehensive community teaching hospital in Michigan, with the expectation that it can lead to improved organizational outcomes in both the short run (e.g., reduced length of stay [LOS]) and the long run (e.g., reduced patient readmission and improved patient satisfaction). The hospital implemented MDR in various units as a process innovation to improve patient engagement and patient satisfaction. The initial phase of MDR implementation was nurse-led to gain feedback from patients at three time periods (30, 60 and 90 days) on patient services. The hospital revised the MDR process in the second phase into a doctor led patient education process. While the results to date are not conclusive, they do show how MDR can be used by hospitals to engage patients inside the hospital to gain feedback for continuous improvement, using technology when appropriate, and support patient education on care plans post-discharge.
A Longitudinal Study on the L2 Word Depth Knowledge (Meaning and Collocation) Development in China from Dynamic Systems Theory Perspective
Authors: Dali Ning
Published: July 2018

This study, adopting a longitudinal approach, traces the dynamic word knowledge development of two essential dimensions (meaning and collocation) both receptively and productively in Chinese context. Seven freshmen students (from the same class in a university in Guangzhou) of different language levels were selected to be observed of their English word knowledge development over one year’s time. The results suggest that word knowledge develops with slowdowns and recessions and the dimensions of knowledge develop in an unbalanced way, an indication of the dynamic and complex nature of language learning. Receptive knowledge shows a much more active development than productive knowledge as it grows faster but with more losses as well. Collocation though always shows poorer acquisition results in the two tests, demonstrates a faster growth than meaning knowledge. As to the individual differences, participants who were tested as the higher level of learners did not always show better development in word depth knowledge during the year. The results also reveal the participants’ learning preferences (e.g. passive learning style and active learning style). This study sheds light on the L2 vocabulary learning and teaching in Chinese context.

Acetic acid (CH3COOH) is produced naturally through anaerobic fermentation (vinegar) or synthesized through various industrial chemical methods. The primary components of vinegar are water and acetic acid. Acetic acid can destroy cell membranes, which then can result in plant tissue desiccation and plant death. Therefore, vinegar has the potential as a natural contact herbicide for the control of weeds in organically produced crops. Additional information is needed to determine the influence of acetic acid concentration, application volume, and adjuvants on weed control. Typically, household vinegar contains 5% acetic acid and greater acetic acid concentrations are available commercially. Field research was conducted in southeast Oklahoma (Lane, OK) to determine the effect of acetic acid concentrations, application volumes, and adjuvants on weed control efficacy. The factorial experimental design included three acetic acid concentrations (0, 5 and 20%), two sprayer application volumes (187 and 935 L/ha), three adjuvants (none, orange oil, and canola oil), and one weedy-check. The experiment was repeated twice. Visual weed cover and control ratings were collected 4 days after treatment. The experiment had very high weed densities with multiple grass and broadleaf weed species. The weedy check average weed cover percentages were 98% total weeds, 53% grass, 44% broadleaf weeds, 52% large crabgrass (Digitaria sanguinalis (L.), 25% carpetweed (Mollugo verticillata L.), and 14% cutleaf evening primrose (Oenothera laciniata Hill). Total weed control ranged from 0% control (no acetic acid) to 74% control (20% acetic acid, 935 L/ha, & canola oil). Acetic acid was more effective in controlling broadleaf weeds than in controlling grasses. Optimum total grass and crabgrass weed control occurred with 20% acetic acid applied at 935 L/ha, resulting in weed control that ranged from 44% to 63%. Broadleaf weed control was 84% or greater for plots receiving either 10% acetic acid applied at 935 L/ha or 20% acetic acid applied at 187 or 935 L/ha. In addition, 5% acetic acid applied at 187 L/ha provided good cutleaf evening primrose control (77% to 90%). When averaged across application volumes (187 and 935 L/ha) and adjuvants (none, orange oil, and canola oil), weed control increased for all species as acetic acid concentrations increased from 5% to 20%. When averaged across acetic acid concentrations and adjuvants, weed control increased as application volumes increased from 187 to 935 L/ha. Individual comparisons among adjuvants within acetic acid concentrations and application volumes showed little or no advantage to adding either orange oil or canola oil to vinegar spray solutions.

Ethofenprox, pyraclostrobine, trifloxystrobin and enestroburin are strobilurin fungicides that can effectively control fungal diseases caused by ascomycetes, zygomycetes, imperfect fungi, etc. With the purpose of guaranteeing the safe use of strobilurin fungicides in the prevention and treatment of citrus diseases, toxicity and control effects of the fungicides on citrus storage diseases and GC-MS (gas chromatography-mass spectrometry) were applied in this study to determine its residual safety. The results indicated that ethofenprox, trifloxystrobin, pyraclostrobine, and enestroburin had excellent inhibitory effects on citrus storage diseases at concentration of 200-400 ug/mL. Degradation dynamics of 4 fungicides during the storage period of citrus could be expressed as the first-order kinetics equation. The fungicides could penetrate into flesh through peels slowly. Therefore, the residue content of the fungicide on peels was higher than that in the flesh of the same citrus. After citrus fruits were treated for 90 d, the residues were lower than the maximum residue limits in all the countries, so the citrus were safe. This investigation provided the theoretical guidance and technical support for the quality evaluation of citrus products.

Published: July 2018

This study aimed to characterize 41 isolates of Trichoderma from conventional cotton crops soils as the morphological and cultural characteristics and to investigate polymorphism, using RAPD markers. The most common group comprised 80.6% of the isolates and was identified as a strain of Trichoderma harzianum. The others species were T. aureoviride (7.3%), T. viride (7.3%) and T. crassum (4.8%). The four species were morphologically distinct in the evaluated characteristics such as colony appearance and mycelium growth rate after being grown on malt extract agar (MEA), potato dextrose agar (PDA) and oatmeal agar (OA) media, and also in shape of conidia, phialides, and conidiophores. The four species were separated in a dendogram, after using RAPD markers. Besides, RAPD was efficient in demonstrating the high intraspecific genetic variation among isolates of two species (T. harzianum and T. aureoviride).

Published: July 2018

Overall appearance on everbearing strawberry cultivar, ‘Dekoruju’ berries were observed. Berries were glossy and colors of skins and pulps were favorable (red-fleshed). An eating quality was good and berries had a favorable balance of sweetness and sourness because of higher sugar-acid ration (14.6) of berries. Berries were foods rich in vitamin B1 (0.35±0.02 mg/100 g FW) and phenol compounds (80.4±0.6 mg/100 g FW) such as anthocyanins and flavonoids. Extracts prepared from berries, especially in 100% concentration, almost completely inhibited linoleic acid peroxidation under the condition tested. These showed extremely high scavenging activities against specially superoxide anion (92.2±2.16%) and DPPH (> 100%) radicals in comparison with all commercially available natural or synthetic antioxidants tested. These also exhibited the foremost inhibitory activities against not only ACE (62.7±5.1%) but also hyaluronidase (67.6±3.5%), suggesting beneficial effects on anti-hypertension, anti-allergy, and anti-inflammatory. The present study indicated that fresh ‘Dekoruju’ berries may be considered as good sources of natural antioxidants such as phenol compounds (anthocyanins and flavonoids), and may contribute to maintain and promote health and to help protect body against chronic diseases and an allergy disease.

Cassava resistance to Bemisia tabaci is a result of many plant processes which involve plant biochemical constituents, shown to be affected by genotype and environment. The objective of this study was to assess the effect of genotype × environment interactions on concentrations of tannin, flavonoid, total phenolic content, antioxidative capacity and B. tabaci resistance. Fifteen cassava genotypes were evaluated monthly for tannin, flavonoid, total phenolic content and antioxidative capacity in three locations over two seasons with varying temperatures and rainfall. In addition, data were collected on B. tabaci population density and damage. The data collected was subjected to analysis of variance and additive main effects and multiplicative interactions (AMMI) analyses. Flavonoid, total phenolic content and antioxidative capacity varied significantly (P < 0.001) across seasons with higher concentrations in season one than season two, attributed to different temperature and rainfall readings. Total phenolic content was significantly (P < 0.001) associated to antioxidative capacity (r = 0.83) and temperature (r = 0.91). Leaf damage due to adult whitefly and nymphs was significantly (P < 0.001) negatively correlated (r = -0.67) to antioxidative capacity. Genotypes UG 120257, UG 120291 and UG 120124 were shown to have high antioxidative capacity and more stable performance across environments. Temperature and B. tabaci feeding influenced concentrations of the phenolic content and antioxidative activity, as a result affected cassava resistance.
