In‐Season Canopy Reflectance Can Aid Fungicide and Late‐Season Nitrogen Decisions on Winter Wheat
Authors: Cruppe Giovana , Edwards Jeffrey T. , Lollato Romulo P.
Published: August 2017

Core Ideas

Wheat grain yield response to foliar fungicide is highly dependent on environment.

Late‐season N can offset protein dilution from fungicide‐driven yield increase.

Foliar N rates necessary to impact grain protein have potential for leaf burn.

Controlled‐release N and urea ammonium nitrate both impacted wheat responses similarly.

In‐season canopy reflectance can aid in fungicide decision.

Winter wheat (Triticum aestivum L) response to foliar fungicide and late‐season N is inconsistent. We evaluated various late‐season N fertilizer‐by‐foliar fungicide combinations to test whether wheat anthesis normalized difference vegetative index (NDVI) could aid fungicide decisions. Six site‐years were conducted with N fertility >120 kg N ha−1 during 2012–2013 and 2013–2014 in Oklahoma, using a three‐way factorial arrangement of a randomized complete block design with four replications. Fungicide treatment (with or without), foliar N source (urea ammonium nitrate [UAN] or controlled‐release N), and N rate (0, 2.8, 5.6, or 28 kg N ha−1) were applied during anthesis. Statistical analyses were performed by site‐year, by yielding environment (low [LY] <3.2 Mg ha−1 and high [HY] >3.2 Mg ha−1), and pooled across site‐years. Grain yield was 0.21 Mg ha−1 greater due to fungicide in the pooled analysis, mostly led by the 0.59 Mg ha−1 yield advantage in HY as opposed to non‐significance in LY. Fungicide increased test weight in 6 to 7 kg m−3 across all analyses, and 28 kg N ha−1 increased grain protein by ∼10 g kg−1 but caused leaf burn. Anthesis NDVI <0.6 occurred when preanthesis abiotic stresses restricted yield potential, not warranting fungicide application. Fungicide can benefit grain yield and test weight and could be considered when anthesis NDVI >0.6, but yield response will depend on grain‐filling conditions. Foliar N rates needed to increase grain protein in a well‐fertilized crop have potential for leaf burn.

The geographic scope, scale, and unique collaborative arrangement warrant documenting details of this work.

The purpose of this article is to describe how the research was undertaken, reasons for the research methods, and the project's potential value.

The project generated a valuable dataset across a wide array of weather and soils that allows evaluation of N decision tools.

Due to economic and environmental consequences of N lost from fertilizer applications in corn (Zea maysL.), considerable public and industry attention has been devoted to the development of N decision tools. Needed are research and databases and associated metadata, at numerous locations and years to represent a wide geographic range of soil and weather scenarios, for evaluating tool performance. The goals of this research were to conduct standardized corn N rate response field studies to evaluate the performance of multiple public‐domain N decision tools across diverse soils and environmental conditions, develop and publish new agronomic science for improved crop N management, and train new scientists. The geographic scope, scale, and unique collaborative arrangement warrant documenting details of this research. The objectives of this paper are to describe how the research was undertaken, reasons for the methods, and the project's anticipated value. The project was initiated in a partnership between eight U.S. Midwest land‐grant universities, USDA‐ARS, and DuPont Pioneer. Research using a standardized protocol was conducted over the 2014 through 2016 growing seasons, yielding a total of 49 sites. Preliminary observations of soil and crop variables measured from each site revealed a magnitude of differences in soil properties (e.g., texture and organic matter) as well as differences in agronomic and economic responses to applied N. The project has generated a valuable dataset across a wide array of weather and soils that allows investigators to perform robust evaluation of N use in corn and N decision tools.
Structural Equation Model of Total Phosphorus Loads in the Red River of the North Basin, USA and Canada
Authors: Ryberg Karen R.
Published: August 2017

Attribution of the causes of trends in nutrient loading is often limited to correlation, qualitative reasoning, or references to the work of others. This paper represents efforts to improve causal attribution of water‐quality changes. The Red River of the North basin provides a regional test case because of international interest in the reduction of total phosphorus loads and the availability of long‐term total phosphorus data and ancillary geospatial data with the potential to explain changes in water quality over time. The objectives of the study are to investigate structural equation modeling methods for application to water‐quality problems and to test causal hypotheses related to the drivers of total phosphorus loads over the period 1970 to 2012. Multiple working hypotheses that explain total phosphorus loads and methods for estimating missing ancillary data were developed, and water‐quality related challenges to structural equation modeling (including skewed data and scaling issues) were addressed. The model indicates that increased precipitation in season 1 (November–February) or season 2 (March–June) would increase total phosphorus loads in the basin. The effect of agricultural practices on total phosphorus loads was significant, although the effect is about one‐third of the effect of season 1 precipitation. The structural equation model representing loads at six sites in the basin shows that climate and agricultural practices explain almost 60% of the annual total phosphorus load in the Red River of the North basin. The modeling process and the unexplained variance highlight the need for better ancillary long‐term data for causal assessments.

Core Ideas

Multiple working hypotheses for the causes of total phosphorus loads were developed.

Challenges associated with water‐quality and related ancillary data are addressed.

Hypotheses with appropriate data were tested with structural equation modeling.

Climate and agricultural practices explain 57% of the variation in the load.

Climate has a greater effect on P loads than do agricultural practices.
Cotton Germination and Emergence under High Diurnal Temperatures

Published: August 2017

In tropical climates, high soil temperatures during the cotton (Gossypium hirsutum L.) planting season impair seed germination and plant emergence, resulting in poor stand establishment. Under these conditions, the performance of cultivars presently in use is not known. The aim of this study was to evaluate germination and emergence of cotton cultivars under diurnal high temperature cycles without water restriction. Three experiments were conducted in germination chambers, testing six cotton cultivars and four diurnal cycles with maximum temperatures of 20, 30, 40, and 50°C. The diurnal cycle with a maximum temperature of 30°C resulted in the greatest germination and emergence rates. Under a maximum diurnal temperature of 40°C, cultivars with higher seed weight were the least impaired, resulting in higher germination and emergence rates than cultivars with smaller seeds. There was a positive correlation between seed weight and seedling length (r = 0.57), as well as seedling dry weight (r = 0.56). The seeds of modern cultivars developed for tropical environments are tolerant to maximum daily temperatures up to 40°C, which is higher than previously reported for older cultivars. However, seed exposure to a temperature of 50°C for only 5.5 h is enough to impair the germination and prevent emergence. The correlation between seed weight and seedling dry weight is positive and greater as the temperature increases or decreases from 30°C, showing that the initial seed weight is determinant for the final seedling dry weight under temperatures departing from the optimal.
Genomic Constitution and Relationship in Urochloa (Poaceae) Species and Hybrids
Authors: Pinto de Paula Cristina Maria , Sobrinho Fausto Souza , Techio Vânia Helena
Published: August 2017

Urochloa P. Beauv. [syn. Brachiaria (Trin.) Griseb.] belongs to the family Poaceae and comprises species presenting different ploidy levels and modes of reproduction. Specific studies on genomic constitution and relationship within the genus Urochloa are limited, despite the great economic and agronomic importance of forage species and the high frequency of polyploids. Therefore, molecular cytogenetic analyses can enhance the knowledge about genomes and their differentiation, which allows making inferences about phylogenetic and genomic relationships. The current study aimed to investigate the genomic relationships between Urochloa ruziziensis (R. Germ. & Evrard) Crins (syn. Brachiaria ruziziensis Germain & Evrard.) cultivar ‘Kennedy’, Urochloa decumbens (Stapf) R. D. Webster [syn. Brachiaria decumbens (Stapf)] cultivar ‘Basilisk’, Urochloa brizantha (Hochst. ex. A. Rich.) R. D. Webster [syn. Brachiaria brizantha (A. Rich.) Stapf] cultivar ‘Marandu’, and their interspecific hybrids by means of genomic in situ hybridization, fluorescent in situ hybridization, and nuclear genome quantification by flow cytometry. We proposed the genomic constitution of U. ruziziensis, U. decumbens, and U. brizantha, such as B2B2, B1B1B2B2, and BBB1B1, respectively. Genomes B, B1, and B2 were considered to be homoeologous, but there was less affinity between genomes B and B2.

Published: August 2017

Patau's syndrome, trisomy 13, is associated with multiple abnormalities of various organ systems, all of which present a challenge to the anaesthetist. Mortality in infancy is high; therefore there are few published reports regarding the anaesthetic management of patients with Patau's syndrome. Our case report describes the anaesthetic management for a 15‐month‐old male who underwent elective cleft palate repair and we review previous published cases. Anaesthetic considerations and the common abnormalities found in Trisomy 13, such as craniofacial, cardiac and renal defects are discussed.
Emergent contaminants in the wastewater effluents of two highly populated tropical cities
Authors: Soler-Llavina Sheila M. , Ortiz-Zayas Jorge R.
Published: August 2017

Exposure to the anthropogenic chemicals known as endocrine disrupting compounds (EDCs) may result in negative biological effects. Low levels of EDCs in the environment aggravate the problem as exposure is constant. Urban areas concentrate pollution as greater volumes are released from human activities. Water for public supply is particularly vulnerable as the sewage treatment facilities may not eliminate EDCs. The goal was to assess estrogenicity and effectiveness of removal of phthalates in primary and tertiary wastewater treatment facilities in urban cities in the tropical island of Puerto Rico. A yeast bioassay used to measure estrogenicity showed higher removal with tertiary treatment. However, results in the picomolar range suggest low doses of estrogenic compounds were being released to receiving waters. For the phthalates, solid phase extraction and gas chromatography-mass spectrometry analyses revealed removals ranging from 42.9% to 92.4% with tertiary treatment. More than 90% removal was achieved for benzylbutyl phthalate, dibutyl phthalate and bis-2-ethylhexyl phthalate. However, concentrations ranging from 0.86 to 1.29 ppm for the phthalates in the outflow were detected even at the tertiary waste water treatment plant effluent implying failure of EDC removal. These results can assist managers in evaluating pollution control technologies to ameliorate the impacts of EDCs in the tropics.
Optimizing electrocoagulation process using experimental design for COD removal from unsanitary landfill leachate
Authors: Ogedey Aysenur , Tanyol Mehtap
Published: August 2017

Leachate is the most difficult wastewater to be treated due to its complex content and high pollution release. For this reason, since it is not possible to be treated with a single process, a pre-treatment is needed. In the present study, a batch electrocoagulation reactor containing aluminum and iron electrodes was used to reduce chemical oxygen demand (COD) from landfill leachate (Tunceli, Turkey). Optimization of COD elimination was carried out with response surface methodology to describe the interaction effect of four main process independent parameters (current density, inter-electrode distance, pH and time of electrolysis). The optimum current density, inter-electrode distance, pH and time of electrolysis for maximum COD removal (43%) were found to be 19.42 mA/m2, 0.96 cm, 7.23 and 67.64 min, respectively. The results shown that the electrocoagulation process can be used as a pre-treatment step for leachate.
The Emerging Picture of CDK11: Genetic, Functional and Medicinal Aspects
Authors: dos Santos Paparidis Nikolas Ferreira , Canduri Fernanda
Published: August 2017

Cyclin-dependent kinase 11 is a relatively neglected member of the transcriptional
CDKs subfamily, despite possibly being the most versatile CDK in this group. Different
CDK11 variants are known to play essential roles in major cellular processes as
mRNA transcription (CDK11p110), mitosis (CDK11p58), and apoptosis (CDK11p46 and
CDK11p60). Each CDK11 species targets a particular set of substrates related to its functional
background, but all isoforms originate from the CDC2L gene complex in human
chromosome 1p36.2. CDK11p110 is synthesized through regular cap-dependent translation
of CDK11 mRNA, whereas CDK11p58 translation is initiated through an IRES, and
occurs only at G2 and M phases. CDK11p46 and CDK11p60, in turn, are the products of
caspase cleavage of the larger isoforms during apoptosis. L-type cyclins are the main
partners of CDK11, although CDK11p58 species interacts specifically with cyclin D3.
The link between CDK11 dysfunction and cancer has been known for a long time, and
critical roles in the proliferation of different cancer cell lines have been assigned to
CDK11. This review summarizes more than 25 years of studies that unraveled CDK11
genetic and functional aspects.
Statins in Aortic Stenosis

Published: August 2017

Calcific aortic stenosis (AS) is the most common form of valvular heart disease in Europe and North
America. It is a progressive disease with a prolonged period of asymptomatic latency which eventually leads to
critical left ventricular outflow tract obstruction necessitating surgical replacement of the valve. Statins are lipidlowering
drugs with a robust evidence base demonstrating clinical benefit in atherosclerotic coronary artery disease.
There has therefore been significant interest in the potential benefit of statins in AS. Initial animal, retrospective
and non-randomized prospective studies suggested a beneficial effect of statins in AS. However, the
outcomes of 3 major randomized controlled clinical trials consistently failed to demonstrate any significant benefit
of lipid-lowering therapy on progression or clinical outcomes in AS. Consequently, statin therapy should not
be recommended if the sole purpose is prevention of AS progression and there is no other indication for lipidlowering
therapy. However, recent data have suggested that lipoprotein(a) (Lp(a)) may play a previously unknown
but critical role in the progression of AS. Lp(a) is not significantly modified by statin therapy and there is
therefore significant emerging interest in targeted reduction of Lp(a) with novel therapeutic agents such as
PCSK9 inhibitors and antisense oligonucleotides.
The Effects and Action Mechanisms of Phytoestrogens on Vasomotor Symptoms During Menopausal Transition: Thermoregulatory Mechanism
Authors: Hairi Haryati Ahmad , Shuid Ahmad Nazrun , Ibrahim Nurul ‘Izzah , Jamal Jamia Azdina , Mohamed Norazlina , Mohamed Isa Naina
Published: August 2017

Background:

Phytoestrogens have recently been claimed to positively influence menopausal discomforts, including hot flashes. However, little is known about the influence of phytoestrogens on core body temperature during oestrogen fluctuation at menopause.

Objective:

Previously published findings showed that phytoestrogens could relieve menopausal complaints, thus, the present review was aimed at assessing the effects of phytoestrogens on thermoregulatory mechanism during menopausal transition.

Results:

The molecular mechanisms underlying hot flashes are complex. Oestrogen fluctuations cause hypothalamic thermoregulatory centre dysfunction, which leads to hot flashes during menopause. The phytoestrogens of interest, in relation to human health, include isoflavones, lignans, coumestans, and stilbenes, which are widely distributed in nature. The phytoestrogens are capable of reducing hot flashes via their oestrogen-like hormone actions. The potential effects of phytoestrogens on hot flashes and their molecular mechanisms of action on thermoregulatory centre are discussed in this review.

Conclusion:

The effects of phytoestrogens on these mechanisms may help explain their beneficial effects in alleviating hot flashes and other menopausal discomforts.

La responsabilidad social del educador en el ámbito pedagógico no se inicia, como puede ser del pensar de muchos, con el abecedario, sino desde la Constitución Política de cada Estado, al señalar los requerimientos, prioridades y fines que la educación debe cumplir, según el ideario de cada nación. En el caso particular de Colombia, la Carta Magna concibe la Educación como “uno de los derechos fundamentales de la persona” (art. 44) y como “un servicio público con función social... que formará al colombiano en el respeto a los derechos humanos, la paz y la democracia...” (art. 67). Este ideal se orienta, en primera instancia, hacia el sujeto de la Educación, es decir, el estudiante, puesto que es él, la persona inmersa en el complejo proceso de educarse, mientras que para el otro sujeto de la Educación, el formador o educador, entendido como el ser social que acompaña, como contrapartida, a quien se halla en circunstancias de formación, la Constitución expresa que “la Enseñanza estará a cargo de personas de reconocida idoneidad ética y pedagógica”. Culmina el artículo con una sentencia, esta vez dirigida al Estado: “La Ley garantiza la profesionalización y dignificación de la actividad docente”.

Published: August 2017

The procedure for innovations in animal exploitation has involved over the long term all over the world. Some of them have compromised the limits of ethics, notably on the use of production animals. In this context, the scenario of social control over the use of production animals began to be increasingly evidence. Bioethics and the science of well being have been contributing to the analysis of the whole process of control over animal raising, opening the way for the idea of dignity among all forms of life. In this way, it is worth considering the growth of national cattle production. Each passing day the demand of meat and milk production chain makes cattle exploitation even more intense. There is no doubt that this intensity has important economic and social gains, but it also has an effect on animal welfare and the limits of ethics. We believe in the possibility of developing new animal raising techniques that guarantee good productivity and high product quality without compromising animal welfare. In the raising system the pregnancy management and the assistance to labor to the bovine female should be differentiated, to the fact that this animal is included in a special category. Based on this context, this article aims to address the relationships established between man and cattle, aiming to discuss pregnancy management and labor assistance, in the most human form possible, considering the ethical and welfare aspects.

Published: August 2017

Pautando-nos na ideia da Alfabetização Científica como um propósito do Ensino de Ciências e nas recentes proposições de que para alcançá-la devemos favorecer o engajamento dos estudantes em práticas da cultura científica, este trabalho pretende analisar a produção de explicações e argumentos numa atividade didática baseada em investigação a fim de caracterizar a mobilização pelos estudantes do conhecimento teórico e empírico ao se engajarem nessas práticas. Analisando os relatórios científicos elaborados pelos alunos do 1º ano do Ensino Médio ao final da atividade investigativa sobre dinâmica populacional, evidenciamos a importância do conhecimento empírico referente ao contexto de investigação como repertório para a construção de explicações, especialmente quando os estudantes lidavam com dados anômalos ao modelo explicativo já conhecido. Esse conhecimento também se revelou importante para a produção de argumentos válidos, visto que a maior parte das justificativas empreendidas foi de natureza empírica, independente se os dados estavam ou não de acordo com o modelo explicativo já conhecido. Esses resultados reforçam a importância da participação dos estudantes em atividades investigativas, como já defendido por diferentes autores desta área de pesquisa, como também indicam que a prática de investigação propiciou o engajamento em práticas epistêmicas, pois o conhecimento sobre as condições experimentais e os procedimentos de coleta de dados forneceu repertório para a produção de explicações e argumentos. Por fim, discutimos a relevância desta pesquisa para o campo do Ensino de Biologia, buscando defender a promoção de atividades investigativas com enfoque experimental como possibilidade de integrar objetivos conceituais e epistêmicos e ultrapassar as dificuldades geradas pelas especificidades desta área do conhecimento em relação às demais disciplinas do campo das Ciências da Natureza.

Abordar en la escuela cuestiones socioambientales como el uso y la gestión del agua en una ciudad supone el reto para los docentes de situarse y operar con fenómenos complejos en entornos también complejos. En este contexto parece significativo apostar por nuevas formas de acercarse al entorno que prioricen las conexiones entre fenómenos, entre espacios y entre niveles escalares, para capacitar a los ciudadanos no sólo para interpretar y representar el mundo, sino también para actuar y aprender en él. Por un lado, integrar la dimensión escalar en la forma de interpretar y representar el mundo, articulando los fenómenos cotidianos con perspectivas locales y globales. Por el otro, conectar la enseñanza aprendizaje con la diversidad de espacios de la ciudad para aprovechar las oportunidades educativas que ofrecen.  Desde este planteamiento se presenta una investigación cualitativa que explora la dimensión escalar de un grupo de profesores en formación para identificar los desafíos de una formación de profesorado que considere las competencias que posibilitan conectar la escuela con la ciudad, con las personas y con el mundo.

Authors: Azevedo Nathália Helena , Scarpa Daniela Lopes
Published: August 2017

Dada a importância que as concepções de Natureza da Ciência (NdC) têm recebido nas pesquisas da área de Ensino de Ciências, relatamos o processo de elaboração de um instrumento para investigar as concepções de NdC de estudantes de Biologia. Propomos orientações e princípios que podem contribuir em pesquisas que objetivam levantar concepções de NdC. O questionário Visões de Estudantes sobre a Natureza da Ciência por meio da Contextualização em Ecologia (VENCCE) é composto por cinco situações contextualizadas que têm a Ecologia como tema e modelo de estudo para a compreensão das concepções de NdC. Cada situação é acompanhada de afirmações a serem assinaladas conforme o grau de concordância do respondente. O VENCCE fornece um índice que indica o quão informada é a visão de ciência dos respondentes. A confiabilidade do VENCCE foi considerada adequada conforme o Alfa de Cronbach estimado após uma aplicação com 691 estudantes de graduação. Apresentamos aqui o VENCCE na íntegra e discutimos as implicações de utilizar questionários contextualizados. Procuramos ainda justificar nossas decisões epistemológicas e metodológicas a fim de fomentar a reflexão e auxiliar na tomada de decisão de outros trabalhos. Ao expor nossas decisões de pesquisa procuramos generalizá-las para que a metodologia empregada por nós possa ser expandida e replicada durante a elaboração de outros instrumentos de pesquisa em geral. Organizamos nosso percurso na forma de um diagrama de perguntas, que podem ser consideradas para a criação de novos questionários de forma explícita e crítica.

Os objetivos deste estudo foram analisar a relação entre as variáveis: amor (em suas dimensões Intimidade, Paixão e Decisão/Compromisso), beleza, satisfação conjugal e relações familiares (indicadas pela coesão familiar e conflitos familiares) em casais jovens adultos e de meia-idade. Foram investigados 200 sujeitos (50 casais de jovens adultos e 50 casais de meia-idade). Utilizaram-se os seguintes instrumentos: questionário; Escala Triangular do Amor de Sternberg; Escala de Satisfação Conjugal; Escala de Avaliação da Coesão e Adaptabilidade Familiar - Faces III e; Escala de Conflito Conjugal. Constatou-se que os casais de meia-idade apresentaram maior índice de satisfação conjugal do que os casais jovens adultos. Os sujeitos que consideravam seu cônjuge como sendo uma pessoa bonita tinham maior: satisfação conjugal (r= 0,424; p<0,001), intimidade (r= 0,384; p<0,001), paixão (r= 0,372; p<0,001) e decisão/compromisso (r= 0,337; p<0,001) e; sentiam mais amor pelo cônjuge (r= 0,371; p<0,001). Este grupo de casais, também, apresentou maior coesão familiar (r= 0,387; p<0,001) e menos conflitos familiares (r= -0,342; p<0,001). Conclui-se que a percepção favorável da beleza tanto de si quanto do cônjuge exerce influência positiva nas relações conjugais e familiares.Palavras-chave: Amor; Beleza; Satisfação conjugal; Família; Casamento.

First philosophy naturalized: Peirce’s place in the Analytic tradition
Authors: Forster Paul
Published: August 2017

A epistemologia de Charles Sanders Peirce parece paradoxal quando comparada a de Rudolf Carnap e W.V. Quine. Como Carnap, mas diferentemente de Quine, Peirce considera que o conhecimento científico reside em princípios lógicos que devem se sustentar  para que o discurso sobre o verdadeiro e o falso tenha sentido. Ele também compartilha a visão de Carnap de que esses princípios são anteriores à, e independentes das constatações nas ciências naturais, uma visão que Quine notoriamente rejeita. Todavia, como Quine, mas diferentemente de Carnap, Peirce insiste que não há conhecimento além daquele que é obtido por meio de testes empíricos, que as verdades da lógica estão epistemologicamente a par das verdades descobertas nas ciências naturais, e que nos revelam algo sobre como as coisas são, em vez de carecerem de conteúdo fatual, como Carnap afirma. Um ar de paradoxo emerge no comprometimento simultâneo de Peirce às visões comumente consideradas próprias das teorias epistemológicas incompatíveis. A análise desse paradoxo pela comparação da concepção de conhecimento de Peirce ao de Quine e Carnap nos ajuda a apreciar melhor sua importância na tradição filosófica e na profundeza e originalidade de suas razões.

Reduction of Underwater Radiated Noise from Ships: New Shipbuilding Challenge. The Vessels "Ramón Margalef" and "Ángeles Alvariño" as Technological References of How to Build Silent Vessels
Authors: Beltrán Palomo Publio
Published: August 2017

Abatement of noise radiated by all kinds of vessels, and specially Underwater-Radiated Noise, because of its impacton marine life, has become the most outstanding novelty and the most dificult challenge the shipbuilding industryhas ever faced. Hence, the industry seeks to other new solutions to comply with the new guidelines and requirementsthat have been recently introduced and promoted by the EU, marine institutions, and the scientific community. "isnew topic, already studied and solved by the navies because of their strategic requirements, is now in the limelight andall the different aspects are being studied and discussed among the different players mentioned. In this new trend, theappearance of some class notations with “different limits”, assertions such as that the “propeller” is the major noise source,and the absence of consensus among the biological community about what should be the limits (for not affecting marine fauna), it is difficult to define the technological steps that should be followed. Until a consistent agreement is reached, the shipbuilding industry and the naval engineers will be “fighting against a ghost”. Within this “confusing scenario”, this paper is a clear example of how the Spanish shipbuilding industry is moving ahead to reduce the impact of new ships. The dynamic and acoustic design, developed by the authors, of the fishing research vessels “Ramón Margalef” and “Ángeles Alvariño” for the Oceanographic Spanish Institute and the experimental results obtained, in full compliance with ICES N°209 Underwater-Radiated Noise requirements, makes them reference vessels for the construction of “Silent Vessels”.
Fuel-Cell Integration on Board Surface Ships
Authors: Fuentes David Ignacio , De Lavalle Pérez Hernán
Published: August 2017

Given the high levels of air pollution around the world, produced by the emission of greenhouse gases,the shipbuilding industry is in search of a "zero emissions" ship. To achieve this, research groups, havefocused on the further investigation of the fuel cells. These devices can produce energy by only usinghydrogen and oxygen as main power sources, having the next advantages features: low noise production,no emissions, and high efficiency. They can also be integrated with other systems. As Jules Verne wrote inhis “The Mysterious Island”, one day water will be used as fuel. The hydrogen and oxygen that constituteit, used alone and simultaneously, produce inexhaustible heat source and light intensity much greaterthan that of coal.
Solution to the Anti-aircraft Fire Control Problem on a Naval Platform Using the Direct Geometric Model
Authors: Gil Francisco , Vivas Andrés
Published: August 2017

To find the kinematic model in applications different from robotics, the free-body diagram and coordinateconversion using Euler angles is frequently used. In robotics the Khalil-Kleinfinger (1986) method is used(and others), which allows coordinate conversions over several joints. In this paper a new application ofthis method to solve the fire control problem of a naval anti aircraft gun is proposed. To demonstrate theapplication a virtual model is built using Virtual Reality Modeling Language (VRML) and controlledby Matlab Simulink®. From the direct geometric model the solution of the problem is found, includingthe detection system, platform, gun and flight of the missile. This model serves as a tool for the design,testing and integration of controllers for the gun and detection system. The prediction algorithms ofthe trajectory of the target and the missile in flight models can also be integrated. The results show thatthe geometric model of complex systems with many degrees of freedom can be constructed in a precise,methodical and easy to understand manner.
Development of Fire Fighting & Damage Control automation that enables future crew reduction
Authors: Geertsma Rinze , Badon Ghijben Nine , Middeldorp Erik , Ruiter Robin de
Published: August 2017

The Holland-class Patrol Vessels of the Royal Netherlands Navy has been designed to conduct world-wide operations with a low level of violence. Minimization of the exploitation costs has been translated in a frigate size vessel design to be manned by a crew of 50. In particular, the support of Battle Damage Repair required serious development as today’s solutions are based upon having a much larger crew. Adoption of modern fire-fighting techniques such as ship-wide deployment of automated water-mist systems and extensive use of center-fed hose reels appeared to be essential steps to cope with lower manning levels. However, that is not enough as there are other internal battle aspects that (today) require significant manpower such as information gathering to obtain the desired situational awareness of the current state of the damage, and complex engineering tasks to mitigate the damages and the management of the necessary resources. For this reason, this paper discusses the approach and development of four (4) platform management system Damage Surveillance and Control (DSAC) applications as an example how future internal battles can be supported to achieve a higher quality (less human errors) of battle damage control, by means of a better situational awareness and a significant reduction of the workload during Battle Damage Repair.
Structural Analysis of an Aluminum Multihull
Authors: Fuentes David , Salas Marcos , Tampier Gonzalo , Troncoso Claudio
Published: August 2017

Structural analysis of a multihull is relatively complex since the connecting structure introduces additional stress than those typical of a monohull. The aluminum trimaran presented in this work was designed within the framework of the research project “Conceptual Design of a High-performance Vessel for Passenger Transport in Chile’s Austral Zone”. The trimaran was structurally measured using the regulations of classification societies Germanischer Lloyd, Det Norske Veritas y LloydÅLs Register. For the scantlings obtained with each regulation a Finite Element Model was created and the structural analysis for the slamming and splitting moment events was made. The results were analyzed and the stress concentration zones were determined to compare them with admissible stresses and conclude whether the structural sizing adequately and safely responds to the design stresses.
A Bimodal Transportation Model for Steam Coal Exportation Based on Magdalena River as Main Waterway
Authors: Murcia Henry
Published: August 2017

The aim of this work is to offer a new alternative to allow the release of the Colombian coal transportation system that nowadays is under a saturation state. For this reason it is proposed, the option of making the exportation of the surplus production granted by the thermic coal mining activity focused on the Cesar department, through a bimodal transportation system that will highlight on the Magdalena River as the most important way for the logistic development of the country. As main key and support tool, the Discrete Event Simulation (DES) methodology was used for conducting experiments based on information which has given the characterization of the proposed system. Hence, the establishment of the conceptual model that determinated and limit the system, a simulation in the software Rockwell Arena was implemented which results were tested and analyzed to study the performance of itself.
Hull girder: Forced vibration analysis by propeller
Authors: Domínguez Franklin
Published: August 2017

The non-uniform wake around the propeller generates fluctuating forces on the propulsion shaft. This article presents a methodology used for the forced vibrations analysis of hull girder due to this propeller excitation. This approach is applied to a research boat considering the propeller working in the operating range using a finite element model including all ship structures, rudder, and propulsion lines with their respective supports. Added mass and damping in all submerged elements were also considered. Vibration levels acting in the vessel structure are compared with the limits proposed by ISO 6954 (2000).
Evaluation of Medium Speed Diesel generator sets and energy storage technologies as alternatives for reducing fuel consumption and exhaust emissions in electric propulsion systems for PSVs
Authors: Morales Vásquez Cristian A.
Published: August 2017

The use of electric propulsion systems in PSVs in Brazil has recently increased, leading to be the standard for most support vessels. In those ships, the common arrangement uses high speed Diesel generator sets for power generation and induction motors driving propellers, reporting significant reductions in the fuel consumption and exhaust emissions compared with mechanically propelled PSVs. However, further abatements in these parameters could be achieved by implementing other technologies for power production. In this work, the use of medium- speed Diesel generator sets and energy storage technologies in electrically propelled PSVs is evaluated. For the above, the fuel consumption, exhaust emissions, mass, volume and acquisition costs of four arrangements are estimated and compared. Two of the arrangements are equipped with medium-speed Diesel generator sets, two with energy storage units and one with high-speed Diesel generator sets. Energy storage appears as interesting alternative for decreasing fuel consumption and emissions by optimal loading of Diesel engines. Medium speed generators also showed reductions in fuel consumption, but highest emissions. The arrangements with high-speed generators presented the lowest mass, volume and acquisition costs.
