Climate Change Impacts and Water Management Adaptation in Two Mediterranean-Climate Watersheds: Learning from the Durance and Sacramento Rivers
Authors: Andrew John , Sauquet Eric
Published: February 2017

Climate change is bringing more risk and uncertainty to water management in the world’s Mediterranean-climate regions. In this paper, we compare two Mediterranean-climate watersheds: the Durance basin in southern France, and the Sacramento River in northern California, USA. For the Durance basin, we present new research on climate change impacts on water management, and discuss their implications for potential adaptation responses. For the Sacramento River, we review existing climate data and research on impacts and describe the progress in implementing various adaptation strategies. We find that the Durance and Sacramento—while certainly at different scales—nonetheless share many characteristics, such as a highly variable climate and hydrology, and extensive hydromodification and intense water competition, which will be affected by climate change. Although some issues and approaches to adaptation are unique to each region, at the same time, these two river basins are utilizing some similar strategies to cope with a changing climate, such as regional planning and management and water conservation.
Chinese Pictorial Board Game Prints
Authors: Laing Ellen Johnston
Published: February 2017

In antiquity people in China played many board games using set patterns for the players to follow, but apparently these did not include pictorial images. By the late 19th century, however, pictorial game board prints for games involving throwing dice were popular. A wide range of pictorial themes were portrayed in these game board prints. Some thirty-three different pictorial board game prints are known today. Twelve of them are analysed here. Images are arranged in a squared spiral, a spiral, or a wavy spiral ; the motifs are usually placed in the intersection between two lines. Based on the throw of the dice, each player sought to move along each image to ultimately obtain the happiness pictured in the central panel, such as longevity or wealth. The Eight Immortals and the Twelve Animals of the Zodiac were frequent motifs. In addition, many pictorial game board prints with stated themes also include secondary auspicious motifs conveying wishes for longevity and wealth. There are also representations of everyday objects, along with labels, and illustrations to novels. A significant local preference is found in game board prints produced in North China which differ substantially from those printed elsewhere in the country.

Authors: Barhoumi Karim , Darné Olivier , Ferrara Laurent
Published: February 2017

Depuis quelques années, la quantité de données disponibles, économiques et financières, a incité les économètres à développer ou à adapter de nouvelles méthodes afin de résumer de manière efficiente l’information contenue dans ces grandes bases de données. Parmi les différentes méthodes proposées, les modèles à facteurs dynamiques ont connu un développement rapide et un large succès auprès des macroéconomistes. Dans cet article, nous proposons une revue de la littérature récente sur ce type de modèles. Nous présentons d’abord les modèles utilisés, puis les méthodes d’estimation des paramètres et les tests statistiques du nombre de facteurs. Nous nous focalisons ensuite sur quelques applications récentes, portant sur la construction d’indicateurs conjoncturels, la prévision macroéconomique et les analyses macroéconomiques et de politique monétaire.
Un fan chart conditionnel du PIB construit à l’aide des enquêtes de conjoncture de l’Insee
Authors: Cornec Matthieu
Published: February 2017

Les intervalles de confiance, les prévisions en densité et leurs illustrations (les fan charts) permettent de décrire utilement l’incertitude inhérente à toute prévision ponctuelle. Toutefois, les techniques existantes à cet égard présentent plusieurs défauts. Nous proposons une nouvelle méthodologie pour représenter l’incertitude d’une prévision en temps réel, à la fois conditionnelle au contexte économique, non-paramétrique et reproductible. En outre, nous construisons un indice du risque prévisionnel associé à notre fan chart afin de mesurer la difficulté intrinsèque de l’exercice de prévision. Construit à l’aide des soldes d’opinions des enquêtes de conjoncture de l’Insee, notre fan chart du PIB capte la récession de 2008-2009 efficacement en temps réel, tandis que l’indice du risque prévisionnel augmente sensiblement, signe d’une incertitude croissante.
Les divinités d’origine indigène et iranienne sur le monnayage des cités du Pont sous les premiers Sévères
Authors: Dalaison Julie , Remy Bernard
Published: February 2017

C’est sans doute à la fin de 114, que les cités du Pont Galatique et Polémoniaque sont passées de la Galatie à la Cappadoce. Dans leur panthéon «monétaire » , nous retrouvons des divinités d’origine indigène, iranienne et gréco-romaines. Sauf Sebastopolis, les cinq autres cités honorent sur leur monnayage une divinité d’origine indigène ou iranienne, propre à chaque cité. Leur survivance à l’époque sévérienne n’est pas liée à un quelconque regain d’intérêt pour un passé lointain, mais confirme l’importance de l’influence indigène et iranienne dans le Pont. Toutefois, ces divinités ont profondément évolué. Elles sont le résultat d’une histoire au cours de laquelle différentes «couches » se sont superposées.
Le dépôt monétaire d’oboles massaliètes du Castelet à Fontvieille (Bouches-du-Rhône)

La production de l’atelier monétaire d’Ecbatane : mise en perspective historique et financière
Authors: Boillet Pierre-Yves
Published: February 2017

Ecbatane, ancienne résidence royale des Achéménides, siège d’un commandement militaire sous les Séleucides, capitale de la Médie, reste aujourd’hui encore méconnue. Les monnaies semblent à cet égard pouvoir être d’un certain secours : une étude de coins, conjuguée à une approche quantitative, permet de mesurer la production de l’atelier ; et de la sorte, de mieux appréhender le rôle d’Ecbatane dans le fonctionnement du royaume séleucide. Ecbatane apparaît ainsi comme un centre économique de second plan, loin de l’image transmise par les sources littéraires.
Les monnaies méditerranéennes en Gaule du Nord (150 av.-100 apr. J.-C.). L’apport des contextes archéologiques
Authors: Martin Stéphane
Published: February 2017

According to J.-M. Doyen’s recent study on Ebusan coins found in northern Gaul as

early as the first half of the 1st c. BC, Mediterranean bronze coins were used as currency in this region, which lay outside Roman influence. However, the study of stratified finds makes it likely that the Roman conquest played a great part in bringing such coins (both in bronze and silver) to northern Gaul. They can be linked with the military presence in the region in the years following the Gallic Wars.
Les signes monétaires de l’État français. La numismatique et l’art du billet au service de Vichy ?
Authors: Manas Arnaud
Published: February 2017

The issue of the subordination of money to political power must be treated in a nuanced manner. During World War II, technical and economic constraints predominated. The coins designed under the Vichy régime by Lucien Bazor display some fascist influences, whereas Lucien Jonas’ banknotes clearly have a more neutral tone. The design and iconography of the francisque – a doubleheaded axe that became the symbol of the Vichy regime – can be traced to Lucien Bazor. He drew on classic numismatic representations of the French Republic and on Italian fascist motifs. He also illustrated Vichy’s political conceptions on a medal depicting a European Ara Pacis. Lucien Jonas’ banknotes, which had mainly been designed before the war, depict masterpieces of French art and were above all intended to glorify France.
Autour des monnaies Hồng Đức thông bảo de Thánh Tông des Lê (1460-1497)
Authors: Thierry François , Blet-Lemarquand Maryse
Published: February 2017

The Hồng Đức thông bảo coinage of Emperor Thánh Tông (1460-1497) of the Lê Dynasty can be divided in three types according to both the type and the calligraphy, with type 3 characterised by heavy calligraphy and thick characters. Fast Neutron Activation Analysis was performed on about thirty coins. Elemental analyses clearly show that these three types exhibit different compositions. But contrary to the expected results, the alloy of type 3 is the richest in copper and therefore the most costly, whereas type 1 showing the best calligraphy contains the highest proportions of lead. Given the lack of historical sources and reliable archaeological data, the elemental composition provide criteria to propose a relative chronology of the different types of Hồng Đức thông bảo by comparing the composition of former and later coins.
Pollinator‐mediated interactions in experimental arrays vary with neighbor identity
Authors: Ha Melissa K. , Ivey Christopher T.
Published: February 2017

PREMISE OF THE STUDY:

Local ecological conditions influence the impact of species interactions on evolution and community structure. We investigated whether pollinator‐mediated interactions between coflowering plants vary with plant density, coflowering neighbor identity, and flowering season.

METHODS:

We conducted a field experiment in which flowering time and floral neighborhood were manipulated in a factorial design. Early‐ and late‐flowering Clarkia unguiculata plants were placed into arrays with C. biloba neighbors, noncongeneric neighbors, additional conspecific plants, or no additional plants as a density control. We compared whole‐plant pollen limitation of seed set, pollinator behavior, and pollen deposition among treatments.

KEY RESULTS:

Interactions mediated by shared pollinators depended on the identity of the neighbor and possibly changed through time, although flowering‐season comparisons were compromised by low early‐season plant survival. Interactions with conspecific neighbors were likely competitive late in the season. Interactions with C. biloba appeared to involve facilitation or neutral interactions. Interactions with noncongeners were more consistently competitive. The community composition of pollinators varied among treatment combinations.

CONCLUSIONS:

Pollinator‐mediated interactions involved competition and likely facilitation, depending on coflowering neighbor. Experimental manipulation helped to reveal context‐dependent variation in indirect biotic interactions.
Nurse-led Care for Patients with Rheumatoid Arthritis: A Systematic Review of the Effect on Quality of Care
Authors: Garner Stephanie , Lopatina Elena , Rankin James A. , Marshall Deborah A.
Published: February 2017

Objective.

In the nurse-led care (NLC) model, nurses take on the primary responsibility for patient management. We systematically assessed the effect of NLC for patients with rheumatoid arthritis (RA) on multiple dimensions of quality of care from the Alberta Quality of Care Matrix for Health.

Methods.

We searched MEDLINE, EMBASE, and CINAHL from 1950 to January 2015. English-language studies were included if they reported on NLC for patients with RA and assessed 1 or more dimensions of quality (effectiveness, acceptability, efficiency, accessibility, appropriateness, and safety). Data were synthesized using narrative analysis.

Results.

We included 10 studies. The NLC models varied in terms of nurses’ professional designation (clinical nurse specialists or nurse practitioners); however, their role in the clinic was fairly consistent. Disease activity was the most common measure of effectiveness, with NLC being equal (n = 2) or superior (n = 3) to the comparator. NLC was equal (n = 1) or superior (n = 5) versus the comparator in terms of patient satisfaction (i.e., acceptability of care). NLC was equally safe as other models (n = 2). Regarding efficiency, results varied across studies (n = 6) and did not allow for conclusions about models’ cost-effectiveness. In qualitative studies, patients found NLC to be superior in terms of accessibility [i.e., continuity of care (n = 3) and appropriateness measured with education and support (n = 4)]; however, no quantitative measures were found.

Conclusion.

NLC for patients with RA is effective, acceptable, and safe as compared with other models. However, current evidence is insufficient to draw conclusions about its efficiency, accessibility, and appropriateness.

Published: February 2017

Objective.

To ascertain whether strategies of treatment with a biological disease-modifying antirheumatic drug (bDMARD) are cost-effective in an English setting. Results are presented for those patients with moderate to severe rheumatoid arthritis (RA) and those with severe RA.

Methods.

An economic model to assess the cost-effectiveness of 7 bDMARD was developed. A systematic literature review and network metaanalysis was undertaken to establish relative clinical effectiveness. The results were used to populate the model, together with estimates of Health Assessment Questionnaire (HAQ) score following European League Against Rheumatism response; annual costs, and utility, per HAQ band; trajectory of HAQ for patients taking bDMARD; and trajectory of HAQ for patients using nonbiologic therapy (NBT). Results were presented as those associated with the strategy with the median cost-effectiveness. Supplementary analyses were undertaken assessing the change in cost-effectiveness when only patients with the most severe prognoses taking NBT were provided with bDMARD treatment. The costs per quality-adjusted life-year (QALY) values were compared with reported thresholds from the UK National Institute for Health and Care Excellence of £20,000 to £30,000 (US$24,700 to US$37,000).

Results.

In the primary analyses, the cost per QALY of a bDMARD strategy was £41,600 for patients with severe RA and £51,100 for those with moderate to severe RA. Under the supplementary analyses, the cost per QALY fell to £25,300 for those with severe RA and to £28,500 for those with moderate to severe RA.

Conclusion.

The cost-effectiveness of bDMARD in RA in England is questionable and only meets current accepted levels in subsets of patients with the worst prognoses.

L’adolescence dans le cadre de l’adoption internationale met à l’épreuve le lien de filiation et génère un conflit identificatoire. Les enjeux mobilisés sont, pour une part, identiques à ceux rencontrés par tous les adolescents et, pour une autre part, plus complexes. La question du délaissement comme celle du déracinement rendent effectivement nécessaire une greffe à la fois généalogique et socio-culturelle.

Published: February 2017

High Strength Low Alloy (HSLA) steels or microalloyed steels are developed in order toimprove the strength and toughness compared with conventional carbon steels. During the reheatingprocess at 1250-1300 °C for a few hours, the furnace consumes large amount of energy, and the slabsuffers from thick oxide scale. This results in significant mass loss. The long reheating time ensuresmaximum dissolution of the microalloying elements, which must be kept to precipitate duringcooling at the end of the hot rolling process. To minimise the reheating time and save the energyconsumption, this research studied the dissolution kinetics of vanadium in HSLA steel. Vanadium isa main microalloying element added to provide higher strength mainly by precipitation hardening. Itis supposed to be dissolved readily according to the solubility limit. The samples were reheated to1200 °C and 1250 °C for 0, 10, 30, and 60 s. After that the fraction of vanadium dissolved in the solidsolution and the remaining undissolved phases of VC, CN, and V(C,N) were measured bysynchrotron XAS. As soon as the sample reaches as low temperature as 1200 °C, a large atomicfraction of 0.878 of vanadium can be dissolved in the solid solution.

. In this study, characteristics of glass fiber reinforced recycled-PET composites by using direct fiber feeding injection molding (DFFIM) process were studied. The results, when varied processing conditions, indicated that decreasing of matrix feeding screw speed and increasing of number of glass fiber led to the increasing of fiber loading content, respectively. The average fiber length of glass fiber tended to decrease with the increasing of fiber loading content. Tensile modulus and tensile strength exhibited almost linear correlation with glass fiber load content. For study on stability of DFFIM process performance, at earliest stage of DFFIM process, discarding of at least five injected shots must be done in order to prepare the system availability of DFFIM process. The DFFIM machine could uninterruptedly manufacture composites without any problems occurred during 7 hours, which consequently provided high stability of product quality with long-term fabrication.

Published: February 2017

Nowadays Thai farmers confront with the slowdown of rice price problems and the more increasing price of materials. Thus, the expense exceeds the revenue and the farmers do not have enough money. Because paddy rice that farmers sold are contain of more moisture more than 15%, thus the quality of paddy rice is not good. Therefore, the price is cheap based on the quality of paddy rice. Moreover, the consumer demands of rice are steady throughout the year but the rice products are sold by the farmer only after the harvest period. As a result, the price decreased during that period. The merchants/middlemen usually stock rice and resell again afterwards. The paddy silo is the concept for bulk storage of paddy; silo can control storage conditions which will constantly maintain the quality of paddy and prevent access by the rodents, birds and insects. After keep the paddy in silo for the period, the paddy will be sold to the market again at the suitable period. In addition, the qualities of paddy products are not change and the moisture in the paddy will meet the standard.

Authors: Phong Nguyen Thanh , Phuc Van Nguyen , Quyen To Thuy Hoang Le Nguyen
Published: February 2017

Materials account for a significant proportion of engineering and construction projects budget. Therefore, selecting appropriate material supplier criteria is a critical economic decision, and it plays a significant role in the success of any engineering and construction firms. Traditional supplier evaluating decision-making methods are usually based on subjective opinions of experts, resulting in irrational and inappropriate decisions. This paper proposes a quantitative model for selecting a material supplier by using the Fuzzy Analytic Network Process and TOPSIS method. In this model, the material supplier selection criteria are weighted by using Group Fuzzy Analytic Network Process (GFANP). Then material suppliers are ranked using the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) method. The proposed decision-making model can provide a robust approach for solving material supplier selection problems.
Investigation of Thermal Effect on Hot Forging Process of Yoke Flange by Finite Element Modeling
Authors: Sae-Eaw Nuttakorn , Sukpat Mahathep , Aue-u-Lan Yingyot
Published: February 2017

Finite Element Modeling (FEM) has been employed widely to analyze material flow behavior and identify potential defects in a hot forging process before try-out. Normally, the isothermal assumption should be used to simulate this process because the forming time was extremely shot around 0. 5 s – 1 s due to a high velocity of a press machine. However, in some cases when the contact pressure and contact area are extremely high, the heat could significantly dissipate to the forming dies. In case of Yoke flange simulation the isothermal condition could not be used to identify the defect as occurring in the real process. The forging defect (i.e. insufficient gap) was found at the apex of a workpiece in the rough or preform step. In this study, the non-isothermal assumption was used for investigating the defects. The forming process was divided in 3 steps; namely the transportation step when the billet was transferred from an induction furnace to the forging dies by conveyer, the rough forging and the finish forging steps. Temperatures, loads and gaps between workpiece and die at each step of the forming processes were measured and compared with the simulation results. For developing the reliable simulation model, the suitable heat transfer coefficients for each step would be determined. The heat transfer during the forming steps had an effect on the material flow and, the non-isothermal simulation model and could identify the insufficient gap in the rough step.

This study presents the results of the experimental study on the axial compressive behavior of the rubberized concrete under active confinement. Two different mixes of concretes with rubber replacement ratios of 0%, as a control mix, and 18% were prepared. The effects of the incorporation of rubber and the confining pressure on the compressive behavior of concrete were examined through tests of unconfined and actively confined concrete cylinders. The active confinement was applied by a Hoek cell at different pressures, including 5, 7.5, 10, 15, 20, and 25 MPa. The results indicate that the rubberized concrete exhibits lower compressive strength but higher axial and lateral deformation capacities than those of the conventional concrete.

This paper presents the synthesis of a Cu-0.5wt%Nb alloy via mechanical alloying (MA) and subsequent hot pressing. The evolutions of the density, microstructure, microhardness and electrical conductivity of the alloy as a function of the sintering temperatures were investigated. The results show that the microhardness of the alloy decreases with increasing consolidation temperatures, while the density and the conductivity improve. The alloy, subjected to vacuum hot-pressing sintering under 25 MPa pressure and 800 °C for 2h, has a microhardness of 102 HV and an electrical conductivity of 98% IACS. The as processed alloy is characterized by Nb nanoparticles distributed in the submicron sized Cu grains. The microhardness and electrical conductivity of the alloy are closely related with the microstructure, i.e. Cu grain size, as well as the presence and distribution of Nb nanoparticles.

The effects of RE (rare earth) on the corrosion resistance of AlMg5Si1 alloy immersed in seawater in different time were investigated by potential measurements and electrochemical impedance spectroscopy. The results showed that the strengthening phase β (Mg2Si) was short rod like and dispersing distributed in α (Al) in the AlMg5Si1 alloy after adding 0.9% RE. Under the conditions of seawater immersion, the corrosion rate of the AlMg5Si1RE0.9 alloy was less than that of AlMg5Si1 alloy, and the corrosion rate of AlMg5Si1RE0.9 immersed 12h in seawater was the slowest, 5.7 uA·cm-2. The improved corrosion resistance is due to the changes in microstructure and corrosion products.
Transverse Compaction Analysis of 2.5D Preform Composite
Authors: Qu Yang , Dai Ying , Li Han Yang
Published: February 2017

Transverse compaction is an important pattern of deformation during the composite resin transfer molding (RTM) process. Reasonable compaction rate is related to both the composite mould design and the fiber volume fraction of the final composite. In this paper, a mesoscopic geometry model based on CT scanning of 2.5D preform reinforcements is presented. Applying this model to the FEM simulation of transverse compaction, we prove the validation on simulating transverse compaction property of 2.5D preform by comparing to results of compaction test. Orientation angle during the progressive compaction is studied. Using this geometry structure, we build internal and surface RUC respectively then combining together to predict the in-plane mechanical property of 2.5D preform composite. Prediction result is acceptable corresponding to the mechanical properties calculated by homogenized method and compressive stiffness tested by combined loading compression (CLC) experiment.

The role of proinflammatory cytokines in cognitive function has been investigated with both beneficial and possible detrimental effects, depending on the cytokine. More recently, the type 2 IL-4 has been demonstrated to play a role in cognition. In this study, using the Morris water maze task, we demonstrate that IL-13–deficient mice are significantly impaired in working memory as well as attenuated reference memory, both functions essential for effective complex learning. During the learning process, wild-type mice increased the number of CD4+ T cells in the meninges and production of IL-13, whereas neither Morris water maze–trained IL-4 nor trained IL-13–deficient mice were able to increase CD4+ T cells in the meninges. Mechanistically, we showed that IL-13 is able to stimulate primary astrocytes to produce brain-derived neurotrophic factor, which does foster cognitive functions. Moreover, Morris water maze–trained wild-type mice were able to increase astrocyte-produced glial fibrillary acidic protein in the hippocampus, which was impaired in Morris water maze–trained IL-4– and IL-13–deficient mice. Collectively, this study strongly suggests that the Th2 cytokines, not only IL-4 but also IL-13, are involved in cognitive functions by stimulating astrocytes from the meninges and hippocampus. These results may be important for future development of therapeutic approaches associated with neurologic disorders such as Parkinson disease–associated dementia and HIV-associated dementia among others.

Electronmagnetic Compatibility Measurement Procedure for Vehicle Components - Part 21: Immunity to Electromagnetic Fields, 30 MHz to 18 GHz, Absorber-Lined Chamber
Authors:   Electromagnetic Compatibility (EMC) Standards
Published: February 2017

This part of SAE J1113 specifies test methods and procedures for testing electromagnetic immunity (of vehicle radiation sources) of electronic components for passenger cars and commercial vehicles. To perform this test method, the electronic module along with the wiring harness (prototype or standard test harness) and peripheral devices will be subjected to the electromagnetic disturbance generated inside an absorber-lined chamber. The electromagnetic disturbances considered in this part of SAE J1113 are limited to continuous narrowband electromagnetic fields.

Immunity measurements of complete vehicles are generally only performed at the vehicle manufacturer. The reasons, for example, are high costs of a large absorber-lined chamber, preserving the secrecy of prototypes, or the large number of different vehicle models. Therefore, for research, development and quality control, a laboratory measuring method shall be applied by the manufacturers.

Part 1 of SAE J1113 specifies the general, definitions, practical use, and basic principles of the test procedure

Spark Plugs
Authors:   Ignition Standards Committee
Published: February 2017

This SAE Standard applies only to spark plugs used for ground vehicles and stationary engines.

This document is intended to serve as a guide to dimensions common to the majority of current production spark plugs and future applications. It is not the intent of this document to prohibit the manufacture of spark plugs having dimensions differing from those presented. Many applications exist which require specialized or nonstandard spark plugs. It is recommended that this document be used in spark plug design and engine applications wherever possible. Whenever design situations arise that prevent the use of one of these standard spark plugs, a spark plug manufacturer should be contacted for guidance.

Figures 1 to 13 and Tables 1A to 6 show typical configurations of unshielded and shielded spark plug designs, their dimensional characteristics, installation, threaded hole, and spark plug thread sizes.
Changes to the tropical circulation in the mid-Pliocene and their implications for future climate
Authors: Corvec Shawn , Fletcher Christopher G.
Published: February 2017

Abstract. The two components of the tropical overturning circulation, the meridional Hadley circulation (HC) and the zonal Walker circulation (WC), are key to the re-distribution of moisture, heat and mass in the atmosphere. The mid-Pliocene Warm Period (mPWP; ∼ 3.3–3 Ma) is considered a very rough analogue of near-term future climate change, yet changes to the tropical overturning circulations in the mPWP are poorly understood. Here, climate model simulations from the Pliocene Model Intercomparison Project (PlioMIP) are analyzed to show that the tropical overturning circulations in the mPWP were weaker than preindustrial circulations, just as they are projected to be in future climate change. The weakening HC response is consistent with future projections, and its strength is strongly related to the meridional gradient of sea surface warming between the tropical and subtropical oceans. The weakening of the WC is less robust in PlioMIP than in future projections, largely due to inter-model variations in simulated warming of the tropical Indian Ocean (TIO). When the TIO warms faster (slower) than the tropical mean, local upper tropospheric divergence increases (decreases) and the WC weakens less (more). These results provide strong evidence that changes to the tropical overturning circulation in the mPWP and future climate are primarily controlled by zonal (WC) and meridional (HC) gradients in tropical–subtropical sea surface temperatures.
Development of high-resolution multi-scale modelling system for simulation of coastal-fluvial urban flooding
Authors: Comer Joanne , Olbert Agnieszka Indiana , Nash Stephen , Hartnett Michael
Published: February 2017

Abstract. Urban developments in coastal zones are often exposed to natural hazards such as flooding. In this research, a state-of-the-art, multi-scale nested flood (MSN_Flood) model is applied to simulate complex coastal-fluvial urban flooding due to combined effects of tides, surges and river discharges. Cork city on Ireland's southwest coast is a study case. The flood modelling system comprises a cascade of four dynamically linked models that resolve the hydrodynamics of Cork Harbour and/or its sub-region at four scales: 90, 30, 6 and 2 m. Results demonstrate that the internalization of the nested boundary through the use of ghost cells combined with a tailored adaptive interpolation technique creates a highly dynamic moving boundary that permits flooding and drying of the nested boundary. This novel feature of MSN_Flood provides a high degree of choice regarding the location of the boundaries to the nested domain and therefore flexibility in model application. The nested MSN_Flood model through dynamic downscaling facilitates significant improvements in accuracy of model output without incurring the computational expense of high spatial resolution over the entire model domain. The urban flood model provides full characteristics of water levels and flow regimes necessary for flood hazard identification and flood risk assessment.
Unidades didácticas: por una enseñanza asistida de la matemática
Authors: Flores Morales Jairo José , Zamora Díaz Winston Joseph
Published: February 2017

En la labor magisterial, la correcta planificación didáctica debe considerarse uno de los aspectos imprescindibles que garanticen una apropiada enseñanza matemática en los diversos subsistemas educativos. Actualmente, resulta incoherente pensar siquiera que se pueden lograr aprendizajes competenciales en los estudiantes, sin antes haber estructurado el trabajo que se realizará en las diversas sesiones de clase. De ahí, que las unidades didácticas permiten crear un proceso de enseñanza aprendizaje completo, innovador y con acciones pedagógicas que procuran el alcance de las competencias matemáticas en los estudiantes. Si se toman en cuenta los intereses de los estudiantes, sus motivaciones, los contenidos a tratar, las actividades y materiales a implementar, el uso de los recursos tecnológicos existentes, la regulación de aprendizajes, el proceso constante de evaluación, las competencias a desarrollar en los estudiantes y un rol docente que rompa el esquema conformista y tradicional existente, se tendrá como resultado una enseñanza asistida de la matemática, estudiantes que utilizan en su contexto los aprendizajes matemáticos alcanzados y docentes que indagan sistemáticamente la mejor forma de enseñar por medio de la acción y la investigación.
