La tenture des Métamorphoses des Gobelins : émulation artistique et stratégies commerciales
Authors: Bertrand Pascal-François
Published: February 2019

La tenture des Métamorphoses, tissée à partir de 1680 durant une cinquantaine d’années, à la manufacture royale des Gobelins, est une des plus vastes productions tombées des métiers parisiens. Elle a été beaucoup tissée. Elle a toutefois été peu étudiée, essentiellement car il s’agit d’un ensemble non compris dans la production officielle des Gobelins. Les chefs d’atelier travaillaient d’après les cartons appartenant au roi ou d’après des cartons qui leur appartenaient, qu’ils commandaient eux-mêmes à des peintres de renom ou à la gloire naissante. La genèse de la tenture a longtemps été confuse. Il s’agit en fait de deux ensembles conçus à une vingtaine d’années d’écart, comprenant plusieurs jeux de modèles et dont certains sujets sont communs aux deux séries. La première série a très vraisemblablement été réalisée peu avant 1680, à partir de tableaux de différents peintres (Louis Boullogne, Charles Le Brun, René-Antoine Houasse et Charles de La Fosse) appartenant à l’entrepreneur Jean Jans. Dans les premières années du xviiie siècle, un nouveau jeu de cartons a été utilisé, toujours réalisé à partir de tableaux ou de copies de peintures de différents artistes (Louis Boullogne, Antoine Coypel, Charles de La Fosse, Nicolas Bertin, Antoine Dieu et Sébastien Leclerc). Plusieurs de ces modèles étaient des commandes royales pour Trianon, la ménagerie de Versailles et Marly. Certains avaient été exposés aux Salons de 1699 et 1704. Cette communication s’arrête sur les enjeux du tissage de ces peintures. Comment s’est opéré le passage du petit au grand format et du peint au tissé lors de l’exécution des tapisseries ?
Nouvelles hypothèses sur la genèse du décor peint de la salle à manger de l’hôtel Crozat
Authors: Marandet François
Published: February 2019

Dans l’histoire de l’art français du début du xviiie siècle, l’entreprise du décor peint de la salle à manger de la résidence parisienne de Pierre Crozat apparaît comme un épisode à la fois célèbre et insolite. Peu avant sa mort, en 1716, Charles de La Fosse avait en effet entamé des projets pour ce décor, et c’est une tout autre personnalité, Antoine Watteau, qui fut chargée de le poursuivre. Comme La Fosse, il devait représenter chacune des saisons sous la forme de quatre compositions ovales. L’identification d’une série de dessins de Nicolas Vleughels représentant Les Saisons, réalisée vers 1716, et dont le format est celui de dessus-de-porte, serait susceptible de démontrer qu’il avait lui aussi été pressenti pour exécuter ce décor peint. Nicolas Vleughels reste en effet connu pour avoir été un proche à la fois de Pierre Crozat et d’Antoine Watteau. La redécouverte d’une peinture ovale de Charles de La Fosse représentant Le Printemps est également l’occasion d’enrichir l’histoire de cette commande qui semble avoir été inspirée par le Bacchus de Rubens, chef-d’œuvre de la collection de Pierre Crozat aujourd’hui au musée de l’Ermitage, à Saint-Pétersbourg.
Une nouvelle grâce : la peinture religieuse de Charles de La Fosse face à la crise de conscience européenne
Authors: Wile Aaron
Published: February 2019

Cette étude se propose de réexaminer la peinture religieuse de Charles de La Fosse à la lumière de la notion de grâce, comprise dans sa double signification de secours surnaturel de Dieu et de charme indéfinissable. Les grâces divine et esthétique étaient intimement liées au début de l’époque moderne, mais, à la fin du xviie siècle, leur rapprochement était devenu intenable. S’appuyant sur une constellation de débats théologiques, artistiques et rhétoriques contemporains, notre étude tente d’expliquer en quoi la peinture religieuse de La Fosse est symptomatique des rapports de plus en plus ténus entre les deux conceptions. En s’attachant à intégrer ces dernières, ses peintures s’exposent aux problèmes que la grâce présente et en deviennent un véhicule involontaire de l’émergence d’une autonomie picturale moderne.
The Falling Gods: Charles de La Fosse’s Allegory of Autumn as Theme and Variation
Authors: Senkevitch Tatiana
Published: February 2019

La Fosse’s Allegory of Autumn as Bacchus and Ariadne, painted for the ensemble of The Four Seasons conceived by Jules Hardouin-Mansart for the Grand Salon of Marly in 1699, brings into focus the artist’s means of allegorization. This essay analyzes the painting in two interrelated aspects: it considers the mode of temporality in La Fosse’s individual visual poiesis and its bearing on the development of French painting on the cusp of the eighteenth century. Considering the temporality of allegory, the essay seeks to demonstrate how the ensemble of paintings from the Grand Salon signals a new stage in the development of the French academic school, marked particularly by a departure from logos-driven allegories and an embrace of more complex, temporal allegories grounded in a pictorial medium. In addition, the essay points to the emergence of the pictorial mode of lamentation adapted by La Fosse from contemporaneous opera.
Charles de La Fosse et la peinture d’histoire autour de 1700
Authors: Chastagnol Karen
Published: February 2019

En contournant une hiérarchie encore stricte entre les différents types de sujets, la peinture d’histoire atteint sous le règne de Louis XIV une forme hybride. La synthèse des genres picturaux occupe une grande partie de la production chez la plupart des peintres. Des figures majeures de cette génération, La Fosse demeure le seul à ne pas adopter cette évolution. En s’imposant comme le précurseur de l’intégration des modèles vénitiens et nordiques, il renouvelle l’emploi d’un certain coloris et d’une touche libérée. S’il développe des types de figures souriantes qui rendent son style unique, il demeure toutefois fidèle au genre historique originel, ignorant une forme nouvelle qui marque le tournant du siècle chez les autres peintres.

Published: February 2019

Purpose: Colorectal cancer is known as the most common gastrointestinal cancers. As the age increases, the risk for this cancer also increases, so the only way to improve and hope for life in these patients is early diagnosis of the disease. So far, numerous molecular studies have been carried out on microRNAs in colorectal cancer. In addition, since some of them can be identified as cancer biomarkers. Therefore, in this study we have investigated the expression level of Mir-30d and Mir-181a as cancer biomarkers.

Method: The changes of Mir-30d and Mir-181a expression levels in 60 colorectal tumor tissues and 60 adjacent tumor tissues, after RNA extraction and cDNA synthesis were surveyed using the Real Time-PCR method.

Results: The results have reported a considerable reduction in the expression level of Mir-30d in tumor tissues, as well as a significant increase in the expression level of Mir-181a tumor expression in tumor tissues (P<0.05). In addition, the correlation between Mir-30d and Mir181a showed that there was a significant difference between the level of expression of mir-30d with age and TNM stage of CRC (P<0.05), whilst these correlations were not observed for Mir-181a (P>0.05).

De civiele kamer en de prejudiciële procedure: kritisch doch loyaal aan het Hof van Justitie

De civiele kamer van de Hoge Raad treedt steeds vaker op als Unierechter en schuwt niet om te verwijzen. Er is echter weinig bekend over de motieven van de kamer om prejudiciële vragen te stellen en de manier waarop de antwoorden van het HvJ vervolgens worden gebruikt door de kamer. Om deze twee vragen te beantwoorden is er een uitgebreide analyse van de rechtspraak van de kamer uitgevoerd in combinatie met acht interviews met (oud-)raadsheren en A-G’s. Dit artikel toont aan dat de kamer uiterst loyaal is wat betreft het verwijzen en de inbedding ondanks dat raadsheren niet met alle antwoorden van het HvJ even tevreden waren.

De mondelinge einduitspraak – dat smaakt naar méér

In artikel 30p Rv is de mogelijkheid om in civiele zaken mondeling einduitspraak te doen geïntroduceerd. In deze bijdrage wordt op basis van de eerste (gepubliceerde) mondelinge einduitspraken de balans opgemaakt. De gepubliceerde zaken laten verschillen zien in het type zaken waarin van een mondelinge einduitspraak gebruik wordt gemaakt (zowel qua onderwerp als qua complexiteit). Van de mogelijkheid om een mondelinge einduitspraak te doen, zou meer gebruik kunnen worden gemaakt (met het oog op de verwachtingen van partijen, de acceptatie van de uitspraak en de begrijpelijkheid daarvan). De inzichtelijkheid van de motivering voor derden vormt daarbij een punt van aandacht.

Een kritische beschouwing over het Wetsvoorstel ter vereenvoudiging en modernisering van het bewijsrecht

Het recent gepubliceerde ‘Wetsvoorstel tot aanpassing van het Wetboek van Burgerlijke Rechtsvordering in verband met de vereenvoudiging en modernisering van het bewijsrecht’ beoogt het civiele bewijsrecht te vereenvoudigen en te moderniseren. Hiertoe doet de minister voor Rechtsbescherming onder meer de volgende drie voorstellen: (1) partijen worden voorafgaande aan een procedure verplicht bewijs te verzamelen en te delen, (2) de regierol van de rechter wordt vergroot, en (3) de normen voor de verschillende voorlopige bewijsverrichtingen worden gelijkgetrokken. De minister voor Rechtsbescherming streeft naar efficiëntere civiele rechtspleging, maar de auteurs vrezen dat met deze voorstellen het tegenovergestelde wordt bereikt. Zij verwachten dat een bewijsverzamel- en -aandraagplicht en het gelijktrekken van de normen voor voorlopige bewijsverrichtingen zullen leiden tot meer, langere en duurdere procedures. De auteurs vrezen ook dat de voorgestelde bevoegdheid voor de rechter ambtshalve gronden en verweren aan te dragen afbreuk doet aan de meest gewenste rolverdeling tussen de procespartijen enerzijds en de rechter anderzijds. Bovendien kan het afbreuk doen aan de objectieve en subjectieve onpartijdigheid van de rechter.

Misbruik van de wrakingsregeling

Binnen de rechterlijke macht en de literatuur leeft het beeld dat vaker dan voorheen op oneigenlijke wijze gebruik wordt gemaakt van de wrakingsregeling. Of dat daadwerkelijk zo is, kan vanwege het ontbreken van empirisch onderzoek niet worden vastgesteld. In 2018 heeft een aantal ontwikkelingen plaatsgevonden die eventuele oneigenlijke wrakingsverzoeken kunnen terugdringen. De Hoge Raad heeft op 25 september 2018 heldere criteria geschetst voor het toetsingskader van wrakingskamers. Daarnaast hebben de voorzitters van de Raad voor de rechtspraak en het College van procureurs-generaal een globale voorzet gedaan voor wijziging van de wrakingsregeling. Beide ontwikkelingen waren aanleiding voor het schrijven van dit artikel.
Physiologically-based pharmacokinetic simulations in pharmacotherapy: selection of the optimal administration route for exogenous melatonin
Authors: Savoca Adriana , Manca Davide
Published: February 2019

The benefits of melatonin on human body are drawing increasing attention from several researchers in different fields. While its role as cure for sleep disturbances (e.g., jet lag, insomnia) is well documented and established, new functions in physiological and pathophysiological processes are emerging. To investigate these effects, there is need for the characterization of melatonin transport processes in the body and resulting pharmacokinetics. Although recent works propose physiologically-based pharmacokinetic modelling of melatonin, no work has yet highlighted the potential of PBPK simulations to shed light on melatonin pharmacokinetic aspects and discrimination among administration routes. This paper presents, validates, and discusses a versatile PBPK model featuring different ways of administration and compares the resulting pharmacokinetic profiles of intravenous, oral, and transdermal administration, with the goal of understanding which is the optimal route to achieve either physiological and/or supraphysiological melatonin levels.
Prevenção quaternária e educação médica: Uma revisão integrativa após as Diretrizes Curriculares Nacionais do Curso Medicina de 2014
Authors: Garcia Jr Carlos Alberto Severo , Steil Amanda , Miranda Clara Garcia
Published: February 2019

Introdução: De acordo com a Resolução nº 3, de 2014, que institui as Diretrizes Curriculares Nacionais (DCN) do Curso de Graduação em Medicina, o(a) graduando(a) em Medicina deve ter formação geral, humanista, crítica, reflexiva e ética, com capacidade para atuar nos diferentes níveis de atenção à saúde, dentre estes, a prevenção. A investigação diagnóstica deve ser realizada com base nas melhores evidências científicas e conforme as necessidades da pessoa. Nesse sentido, a prevenção quaternária e seus princípios têm relação com os objetivos da DCN. Objetivos: Realizar a intersecção a partir de periódicos científicos brasileiros entre a prevenção quaternária e o ensino médico após a implantação da DCN de 2014. Métodos: Revisão integrativa dos artigos disponíveis nas plataformas da CAPES, Scielo, PubMed e Google Acadêmico, a partir do ano de 2014 até outubro de 2017, por meio das palavras chave “prevenção quaternária” e “educação”. Critérios de exclusão: artigos patrocinados por indústrias farmacêuticas, indisponíveis na íntegra, sem resumo e estrangeiros. Resultados: Foram encontrados 33 documentos e 9 artigos selecionados para análise, voltados principalmente para a prática da prevenção quaternária. Apenas 3 estudos fazem alusão à educação médica. Conclusão: A prevenção quaternária é um tema de grande relevância na prática médica, entretanto, ainda é deficiente na graduação, baseado nas restritas produções disponíveis. Apesar da nova DCN do curso de medicina, o ensino médico no cenário atual é predominantemente voltado para especialidades, dificultando a atuação integral e centrada na pessoa.

Published: February 2019

Apesar dos importantes progressos ocorridos no âmbito da saúde pública no Brasil, as mortes maternas por abortos inseguros representam um desafio persistente. Por tratar-se de condição prevalente na população, a mulher que busca o serviço de saúde por questões relacionadas ao aborto deve encontrar no serviço de atenção primária uma porta de entrada segura e um espaço de diálogo aberto. Considerando que o contexto legal do Brasil é um dos mais restritivos do mundo em relação ao aborto, este texto apresenta ideias de como o(a) médico(a) de família e comunidade pode atuar frente a uma situação de gravidez indesejada, baseado na experiência de outros países, considerando os atributos da atenção primária e o código de ética médica. Por fim, a experiência do Fórum Aborto Legal RS é relatada, no intuito de compartilhar ações concretas visando à qualificação do atendimento às mulheres que recorrem a um aborto permitido por lei. Conclui-se que, no nosso meio, um primeiro passo para avançar no direito ao aborto é fazer cumprir a lei que garante a sua realização em situações específicas e que a atuação dos(as) profissionais da atenção primária na redução de danos parece ser uma estratégia chave para evitar abortos inseguros e, por consequência, reduzir a mortalidade materna.

Novos desafios epidemiológicos e demográficos demandam novas formas de organizar os sistemas de saúde. O presente ensaio propõe a telessaúde como ferramenta organizativa, capaz de suavizar o triângulo de ferro da atenção à saúde e de facilitar a busca pelo triple aim, pelo seu potencial de aumento do acesso e qualidade com redução de custo. A integração da telessaúde ao processo de referência e transição entre serviços assistenciais aumenta a resolutividade da Atenção Primária à Saúde (APS), favorece a coordenação do cuidado, promove adesão terapêutica, diminui reinternações e estimula a prevenção quaternária. Este ensaio propõe a telessaúde como metasserviço que confere densidade tecnológica à APS e permite que ela se torne coordenadora efetiva do cuidado, passando a organizar o fluxo de informações, pessoas e insumos. Frente às inovações propostas, é essencial avaliar o impacto de ações já existentes de telessaúde para viabilizar a sua aplicação como metasserviço de saúde.
What Can Virtue Ethics Offer Pacifists?
Authors: Steyl Steven ,   Eastern Illinois University
Published: February 2019

Though warfare has been a popular subject of inquiry in Aristotelian virtue ethics since antiquity, pacifism has almost never been afforded sympathetic study. This paper helps to fill that lacuna by asking whether and how secular virtue ethics can provide a theory of pacifism, whether and how it might defeat some common/foreseeable objections, and what additional work needs to be done in order for virtue ethicists to provide a philosophically robust account of pacifism. I begin by translating a pacifist argument from suffering into an argument from the virtue of compassion. Compassionate agents, sensitive as they are to others’ plights, will be highly averse to lethal warfare. In the second section, I argue that cases for pacifism like this one, which are rooted in individual virtues, cannot constitute a complete argument for pacifism because of the commonly held view that the virtues are reciprocal/unified, and that such an argument will therefore require supplementation in order to be action-guiding. The third section elaborates on what I call the impracticality objection. Any convincing account of pacifism will have to respond to this objection, and I argue that virtue ethical pacifism is especially vulnerable to it. In the fourth section, I highlight two avenues available to the virtue ethicist who defends pacifism from the impracticality objection. Neither of these avenues is viable without further research, however, so while I insist that virtue ethical pacifism is not defeated by the impracticality objection, I maintain also that this form of pacifism requires further scholarly work.
Numerical Study of 3-D Liquid Sloshing in an Elastic Tank by MPS-FEM Coupled Method
Authors: Chen Xiang , Zhang Youlin , Wan Decheng
Published: February 2019

The sloshing phenomenon in a partially loaded oil tanker or liquid natural gas ship is a typical fluid-structure interaction problem involving multi-physics, violent free-surface flow, and nonlinear structural response. In the past decades, the complex phenomenon has been commonly investigated without consideration of the hydro-elastic behaviors of the bulkheads. In our previous work, the liquid sloshing phenomenon in a two-dimensional (2-D) elastic tank was numerically studied. However, the bulkheads of the tank will deform within the three-dimensional (3-D) space in reality. So, it is necessary to study the 3-D sloshing problem in an elastic tank. In this article, a hybrid approach is developed within the Lagrangian system. The moving particle semiimplicit (MPS) method is used to simulate the evolution of 3-D flow with a violent free surface, and the finite element method (FEM) is used for the numerical analysis of structural response due to the impact loads of the sloshing flow. To couple the MPS method and the FEM method, an interpolation scheme based on the kernel function of the particle method is proposed for the communication on the isomerous interface between the fluid and structure domains. The reliability of force and deformation interpolation modules is validated by two tests. Then, the sloshing phenomenon in a 3-D elastic tank is numerically investigated and compared against the previous published 2-D results. By varying the Young's modulus of the tank walls, characteristics regarding the evolutions of free surface, variation of impact pressures, and dynamic responses of the structures are presented.

1. Introduction

To support the transportation demands of natural resources, more and more vessels, such as the very large crude carriers and the liquid natural gas carriers, are manufactured. For these huge structures, risks such as local deformation or even damage of cargo-containment systems resulting from sloshing phenomena subsequently increase. Therefore, it is necessary to take the elasticity of the tank walls into account in the research of sloshing phenomena (Dias & Ghidaglia 2018). However, the phenomena involving the vibrations of the tank walls are complex. In the process of sloshing wave interacting with elastic bulkheads, the fragmentation, splash, and fusion of water are observed. Meanwhile, the structures vibrate nonlinearly under the impact loads resulting from the sloshing wave. These phenomena are hard to simulate realistically by the traditional mesh-based methods.
A fast iris recognition system through optimum feature extraction
Authors: Rana Humayan Kabir , Azam Md. Shafiul , Akhtar Mst. Rashida , Quinn Julian M.W. , Moni Mohammad Ali
Published: February 2019

With an increasing demand for stringent security systems, automated identification of individuals based on biometric methods has been a major focus of research and development over the last decade. Biometric recognition analyses unique physiological traits or behavioral characteristics, such as an iris, face, retina, voice, fingerprint, hand geometry, keystrokes or gait. The iris has a complex and unique structure that remains stable over a person's lifetime, features that have led to its increasing interest in its use for biometric recognition.

In this study, we proposed a technique incorporating Principal Component Analysis (PCA) based on Discrete Wavelet Transformation (DWT) for the extraction of the optimum features of an iris and reducing the runtime needed for iris templates classification. The idea of using DWT behind PCA is to reduce the resolution of the iris template. DWT converts an iris image into four frequency sub-bands. One frequency sub-band instead of four has been used for further feature extraction by using PCA. Our experimental evaluation demonstrates the efficient performance of the proposed technique.
Transcription factors involved in abiotic stress responses in maize (Zea mays L.) and their roles in enhanced productivity in the post genomics era
Authors: Kimotho Roy Njoroge , Baillo Elamin Hafiz , Zhang Zhengbin
Published: February 2019

Background: Maize (Zea mays L.) is a principal cereal crop cultivated worldwide for human food, animal feed, and more recently as a source of biofuel. However, as a direct consequence of water insufficiency and climate change, frequent occurrences of both biotic and abiotic stresses have been reported in different regions around the world, and recently, this has become a major threat in increasing global maize yields. Plants respond to abiotic stresses by utilizing the activity of transcription factors, which are families of genes coding for specific transcription factor proteins whose target genes form a regulon which is involved in the repression/ activation of genes associated with abiotic stress responses. Therefore, it is of uttermost importance to have a systematic study on each family of the transcription factors, the downstream target genes they regulate, and the specific transcription factor genes which are involved in multiple abiotic stress responses in maize and other main crops.

Method: In this review, the main transcription factor families, the specific transcription factor genes and their regulons which are involved in abiotic stress regulation will be momentarily discussed. Great emphasis will be given on maize abiotic stress improvement throughout this review, although other examples from other plants like rice, Arabidopsis, wheat, and barley will be used.

Results: We have described in detail the main transcription factor families in maize which take part in abiotic stress responses together with their regulons. Furthermore, we have also briefly described the utilization of high-efficiency technologies in the study and characterization of TFs involved in the abiotic stress regulatory networks in plants with an emphasis on increasing maize production. Examples of these technologies include next-generation sequencing, microarray analysis, machine learning and RNA-Seq technology.

Conclusion: In conclusion, it is hoped that all the information provided in this review may in time contribute to the use of TF genes in the research, breeding, and development of new abiotic stress tolerant maize cultivars.
Multiple propane gas flow rates procedure to determine accuracy and linearity of indirect calorimetry systems : An experimental assessment of a method.
Authors: Ismail Mohammad , Sana'a Alsubheen A , Loucks-Atlinson Angela , Atkinson Matthew , Kelly Liam P , Alkanani Tim , Basset Fabien
Published: February 2019

Objective: Indirect calorimetry (IC) systems measure the fractions of expired carbon dioxide (FECO2) and oxygen (FEO2) recorded at the mouth in order to estimate whole body energy production (EP). The fundamental principal of IC relates to oxidative mechanisms, expressed as rate of oxygen uptake (V̇O2) and carbon dioxide production (V̇CO2). From these volumes we calculate energy production and respiratory exchange ratio which is used to estimate substrate utilization rates. The accuracy of IC systems is critical to detect small changes in respiratory gas exchanges. The aim of this technical report was to assess the accuracy and linearity of IC systems using multiple propane gas flow rates procedure. Approach: A series of propane gas with different flow rates and ventilation rates were run on three different IC systems. The actual experimental V̇O2 and V̇CO2 were calculated and compared to stoichiometry theoretical values. Results: showed a linear relationship between gas volumes (V̇O2 and V̇CO2) and propane gas flows (99.6%, 99.2%, 94.8% for the Sable, Moxus, and Jaeger metabolic carts, respectively). In terms of system error, Jaeger system had significantly (p < 0.001) greater V̇O2 (M = -0.057, SE = 0.004), and V̇CO2 (M = -0.048, SE = 0.002) error compared to either the Sable (V̇O2, M = 0.044, SE = 0.004; V̇CO2, M = 0.024, SE = 0.002) or the Moxus (V̇O2, M = 0.046, SE = 0.004; V̇CO2, M = 0.025, SE = 0.002) metabolic carts. There were no significant differences between the Sable or Moxus metabolic carts. Conclusion: The multiple flow rates approach permitted the assessment of linearity of IC systems in addition to determining the accuracy of fractions of expired gases.
Pengaruh embung dan kombinasinya dengan teknik konservasi tanah dan air lainnya terhadap koefisien regim aliran dan koefisien aliran tahunan

Published: February 2019

Pemerintah berencana membangun embung sebanyak 30.000 pada tahun 2017. Embung merupakan salah satu metode konservasi tanah dan air untuk menurunkan aliran permukaan, meningkatkan retensi air permukaan dan meningkatkan air yang masuk ke dalam tanah (infiltrasi), yang berakibat langsung terhadap nilai Koefisien Regim Aliran (KRA) atau Koefisien Aliran Tahunan (KAT) suatu DAS. Penelitian tentang pengaruh embung dan kombinasinya dengan teknik konservasi tanah dan air lainnya (strip cropping dan agroforestri) terhadap KRA dan KAT pada DAS Cilemer dengan menggunakan metode SWAT ini dilakukan tahun 2017. Hasil penelitian menunjukkan bahwa Skenario 1 (teknik KTA embung) mampu menurunkan KRA dan KAT masing-masing sebesar 25.45% (dari 119.70 menjadi 94.25) dan 32% (dari 0.25 menjadi 0.17). Skenario 2 (teknik KTA gabungan antara embung dan strip cropping) mampu menurunkan KRA dan KAT masing-masing sebesar 40.92% (dari 119.70 menjadi 78.78) dan 32% (dari 0.25 menjadi 0.17).

Curah hujan yang tinggi pada tanggal 21 Desember 2016 menyebabkan banjir besar di Kota Bima. Banjir tersebut mengakibatkan rusaknya infrastruktur dan menimbulkan kerugian yang cukup besar. Hujan ekstrim, kondisi daerah aliran sungai (DAS) pada bagian hulu yang mengalami pengurangan luas kawasan hutan dan meningkatnya perkembangan Kota Bima diduga sebagai faktor penyebab utama terjadinya banjir besar tersebut. Perubahan penggunaan lahan yang signifikan berdampak pada perubahan respon DAS terhadap hujan yang terjadi. Tujuan penelitian ini untuk mengetahui pengaruh dari perubahan penggunaan lahan terhadap karakteristik banjir yang terjadi berbasis model hidrologi alihragam hujan-aliran pada DAS Rontu di Kota Bima. Pada penelitian ini pengaruh perubahan penggunaan lahan dianalisis dengan cara menentukan nilai curve number (CN) DAS tahun 1996, 2006 dan 2016. CN dihitung menggunakan bantuan perangkat lunak HEC-GeoHMS 10.3. Selanjutnya nilai CN digunakan untuk hitungan hujan efektif sebagai masukan hitungan simulasi hidrograf banjir dengan model alihragam hujan-aliran metode hidrograf satuan sintetik Nakayasu. Hasil penelitian menunjukkan bahwa penyebab banjir selain curah hujan yang sangat lebat atau ekstrim juga dipengaruhi perubahan penggunaan lahan. Pada DAS Rontu selama dua puluh tahun (1996 sampai 2016) terjadi perubahan komposisi penggunaan lahan yaitu pengurangan luas kawasan hutan 28,68%, peningkatan pemukiman 3,10%, peningkatan ladang tegalan 26,83%, peningkatan tanah terbuka 5,82%, peningkatan sawah 3,62%. Akibat perubahan ini pada kondisi basah di sub-DAS Padolo mengalami peningkatan nilai CN 4,55%, debit puncak 10,26% dan volume limpasan 9,82%; pada sub-DAS Malayu mengalami peningkatan nilai CN 6,78%, debit puncak 17,29% dan volume limpasan 18,00%..

Kecamatan Ponjong dan Semanu merupakan dua kecamatan di Kabupaten Gunungkidul yang memiliki morfologi karst beragam dan terdapat dalam gugusan mega sistem Karst Gunung Sewu. Terbentuknya morfologi di kawasan karst, seperti dolina dapat berdampak negatif karena adanya karstifikasi yang dapat menyebabkan amblesan tanah. Oleh karena itu, penelitian ini dibuat dengan melihat karakteristik dan pola persebaran dari dolina. Karakteristik dolina yang ditelitiadalah bentuk medan, kerapatan vegetasi, dan suhu permukaan. Untuk identifikasi karakteristik tersebut menggunakan SRTM dan Citra Landsat-8. Selanjutnya, digunakan analisis morfometri dan indeks Neighbor Nearest Analysis (NNA) untuk melihat karakteristik pola persebaran dolina. Pola persebaran dolina di wilayah penelitian membentuk sebaran mengelompok (indeks NNA 0,843). Di Kecamatan Semanu membentuk pola mengelompok, mengindikasikan perkembangan karstifikasi dolina lebih lanjut jika dibandingkan dengan di Kecamatan Ponjong yang masih cenderung acak. Karakteristik dolina mengelompok terdapat pada bentuk medan dataran rendah dengan kerapatan vegetasi sedang dan suhu permukaan tinggi, sedangkan yang acak memiliki bentuk medan dataran bergelombang dengan kerapatan vegetasi rapat dan suhu permukaan rendah.

Published: February 2019

The abundance, in terms of number of individuals and biomass, of the invertebrate communities in one sector of the soft-bottom continental shelf off Jalisco and Colima (Mexico) was analyzed. The cruises were carried out during three hydroclimatic seasons, as defined by the surface current patterns. Trawl samples were taken from seven sites along the coastline at four bathymetric levels (20, 40, 60 and 80 m), Abundance in the different bathymetric strata was significantly different, but the overall abundance did not vary significantly between seasons. Two bathymetric distribution patterns were found: the first, during the cruises DEM 1 and DEM II, with warm water, presents the greatest abundance at 60 m; the second, during DEM III, with cold water, a low leve1 of dissolved oxygen and the thermocline close to the surface, presents the greatest abundance at 20 m (biomass) and 40 m (number of individuals). The temperature fluctuation in the depth of maximum abundance during the three cruises was 19-2lºC, which suggests a narrow range of thermal preferente in the demersal invertebrate community.
Site-specific sediment quality values for the Gulf of Cádiz (Spain) and San Francisco bay (USA), using the sediment quality triad and multivariate analysis
Authors: DelValls TA , Chapman PM
Published: February 2019

Sediment quality values need to be developed to help protect public health and the environment. Data derived from sediment chemistry, sediment toxicity tests and macrobenthic infaunal community structure from two separate integrative studies (sediment quality triad) conducted in the Gulf of Cádiz and in San Francisco Bay were analyzed by multivariate statistical techniques (principal component analysis [PCA] and factor analysis) to identify the concentration ranges of the chemicals associated with adverse effects. Application of PCA-factor analysis to the data matrix for the Gulf of Cádiz showed that the three data types could be represented by five principal factors, whereas for San Francisco Bay, there were four principal factors. These factors, as well as chemical concentrations and biological effects, were used to establish site-specific sediment quality values for each area studied. Positive prevalence of these factors in the cases studied (seven stations in the Gulf of Cádiz and nine in San Francisco Bay) was used to establish the ranges of chemical concentrations associated with adverse effects. The values proposed for the Gulf of Cádiz, in terms of concentrations at or below which biological effects have been shown to be minimal, are (in mg kg–1 of dry sediment): chromium, 101.2; lead, 66.8; linear alkylbenzenesulphonate, 12.8; silver, 1.2; and mercury, 0.46. The values proposed for San Francisco Bay are (in mg kg–1 of dry sediment): zinc, 156; chromium, 110; nickel, 88; copper, 68; arsenic, 58; lead, 49; tin, 8.0; silver, 4.0; mercury, 0.37; PCBs, 0.057; and DDTs, 0.00224.

A new species, Biffarius debilis, was discovered and represents the fourth species of this genus and the first in the American Pacific.
Effect of three different feeding strategies on phytoplankton, zooplankton and benthos in pacific brown shrimp Penaeus californiensis (Holmes 1900) farming ponds
Authors: Martínez-Córdova LR , Porchas-Cornejo MA , Villarreal-Colmenares H
Published: February 2019

An experimental study was conducted during 23 weeks in Bahia Kino, Sonora (Mexico), to evaluate the effect of three different feeding strategies used in the culture of Pacific brown shrimp, Penaeus californiensis, on the abundance of phytoplankton, zooplankton and benthos. The use of feeding trays (treatment FT) and the complementation of natural food (treatment CNF) promoted a higher abundance of zooplankton and benthic organisms in the ponds. The use of feeding tables (treatment FTA) enhanced the abundance of benthic polychaete species. There were no differences among treatments with respect to chlorophyll a concentration. Growth and yield were higher and feeding conversion ratios lower in treatments CNF and FT. This seems to be related to the higher abundance of zooplankton and benthic organisms in these treatments. Some water quality parameters were also affected by the feeding strategy.

Antes da consolidação de uma reserva de meio de hospedagem, existem diversos fatores que influenciam um consumidor, como as experiências já vivenciadas, as informações adquiridas, as quais com o passar do tempo vem se tornando cada vez mais sofisticadas. Desta maneira, o presente estudo objetivou analisar a percepção dos consumidores sobre a utilização das Online Travel Agencies (OTA) para reservar um meio de hospedagem. Para tanto se descreveu o perfil destes consumidores, verificando a frequência de uso das OTAs quanto ao tipo de viagem, como também comparando suas opiniões em relação ao tipo de viagem e os fatores que influenciam em sua escolha. Dessa forma, nesta pesquisa, caracterizada como descritiva e exploratória, com abordagem quantitativa, foram utilizados estudos anteriores realizados em outros países, tais como Law (2009) e Del Chiappa (2013). Na coleta final foram obtidos 131 questionários com hóspedes de hotéis em Natal/RN. A análise dos dados foi realizada através de estatísticas descritivas, como também comparação de médias (ANOVA) para analisar os objetivos traçados na pesquisa, e do teste Tukey para verificar se realmente existem diferenças de médias entre os grupos. Dentre os principais resultados, foi possível verificar que a maioria dos respondentes (59%) faz parte do grupo dos consumidores ocasionais de OTAs, seguidos dos moderados (30,6%) e um número pequeno (9,9%) faz parte do grupo dos consumidores frequentes. Em relação ao tipo de viagem pode-se concluir que viagens nacionais e de lazer são os tipos mais visados pelos consumidores ao efetuar reservas em OTAs. Tais resultados contribuíram para serem inferidas recomendações para gestores de empreendimentos turísticos, como agências de viagens tradicionais e online.

Published: February 2019

Aims: This study aimed to investigate the relationship between microalbuminuria and hypertension in type 2 diabetic patients.

Study Design: It was a descriptive type of cross-sectional study.

Place and Duration of Study: The study was conducted in collaboration at a diabetic clinic and Hypertension and Research Centre, Rangpur, Bangladesh from January to March 2018.

Methodology: A total of 180 diabetic patients were selected purposively age ranges 30-75 years. Anthropometric as well as biochemical measurement was done. Data was collected by a semi-structured questionnaire through face to face interview and analyzed by SPSS-20.

Results: Study subjects were separated into two groups. Group 1, those with normoalbuminuria (n=49) and Group 2, those having microalbuminuria (n=131). The prevalence of microalbuminuria was 72.8%. Group 2 or microalbuminuric patients showed higher blood pressure values (113.50±8.90 mm of Hg) as compared to Group 1 (101.88±9.80 mm of Hg). The results were statistically significant (P≤0.05). Further this study showed fasting blood sugar, duration of diabetes, systolic blood pressure and high level of sCreatinine were independently associated with microalbuminuria in the study subjects. The results were also statistically significant (P≤0.05).

Conclusion: Our study revealed high prevalence of microalbuminuria in diabetic patients and has an optimistic association with blood pressure. This study suggests the need to screen for microalbuminuria early and the active management of modifiable risk factors in particular fasting blood sugar, sCreatinine, hypertension for intervention and prevention of further complications like end stage renal disease and cardiovascular diseases.
