Stability of Preharvest Sprouting Responses in Great Plains Hard Winter Wheats as Inferred from a Surrogate Assay
Authors: Graybosch R. A.
Published: August 2017

Preharvest sprouting, or precocious germination before grain is harvested, has negative consequences on wheat (Triticum spp.) production and utilization industries. Both genetic and environmental factors predispose wheat genotypes to preharvest sprouting. Using a surrogate assay involving misting of intact spikes, 13 Great Plains adapted winter wheat genotypes were evaluated in terms of environmental stability of preharvest sprouting responses using regression analysis. All entries demonstrated slopes with significant differences from zero, indicating that all responded to changing environments. Entries, however, differed markedly in their responses, with several lines demonstrating slopes with significant negative or positive deviations from 1.0. The hard red winter wheat (Triticum aestivum L.) ‘Camelot’ and the hard white wheat ‘Nuplains’ were found to be most stable (e.g., least responsive) to changing environments. Regression models from stability analyses of these two cultivars were used to identify newly developed genetic materials with potential preharvest sprouting tolerance. Several potential tolerant breeding lines and cultivars were identified and added to the USDA‐ARS National Small Grains Collection, expanding the genetic diversity of useful parental materials capable of contributing to an increase in the frequency of tolerance genes across Great Plains breeding programs.
Septage unit treatment by sludge treatment reed beds for easy management and reuse: performance and design considerations
Authors: Kim Boram , Bel Thomas , Bourdoncle Pascal , Dimare Jocelyne , Troesch Stéphane , Molle Pascal
Published: August 2017

Sustainable treatment and management of fecal sludge in rural areas require adapted solutions. Rustic and simple operating processes such as sludge treatment reed beds (STRB) have been increasingly considered for this purpose. The biggest full scale (2,600 m2 of STRB) septage treatment unit in France had been built in Nègrepelisse with the final objectives of reusing treated sludge and leachates for agriculture spreading and tree irrigation, respectively. The aim of this investigation was to validate the treatment chain of this installation. The obtained field data showed firstly that the overall removal efficiencies of STRB were satisfactory and stable. Removal rates higher than 98% for chemical oxygen demand and suspended solids and a 95% for Kjeldahl nitrogen represented so far a beneficial septage treatment by STRB. The highlighted necessity of a suitable complementary leachate treatment (before tree irrigation) justified the presence of the second stage of vertical flow constructed wetland. The sludge deposit drying and mineralization efficiencies were on the right track. According to hydrotextural diagram analysis, surface deposit was however found to have high deformability probably due to the youth of the installation. An in-depth understanding of STRB system needs continuous long-term studies.
Starch degradation and intermediate dynamics in flocculated and dispersed microcosms
Authors: Ravndal Kristin T. , Kommedal Roald
Published: August 2017

A large fraction of the organic substrate in municipal wastewater is particulate. Prior to uptake, particles have to be degraded through potentially a range of intermediates. However, research on intermediate dynamics during particle hydrolysis is limited. In this paper, batch experiments on flocculated and dispersed biomass microcosms using starch as particulate substrate are reported. Overall hydrolysis rate was not significantly different between the two systems. Particle colonization, and increased particle porosity in combination with particle breakup, led to increased substrate availability over time. Particle breakup was more important for flocculated biomass, while increased particle porosity and particle colonization played a larger role for dispersed biomass. During particle degradation intermediates were formed; however, all intermediate polymer sizes were not formed to the same extent. This can be explained by non-random enzymatic degradation, where some products are preferred over others. Intermediates' dynamics also depend on the biomass structure, and in a floc-based system, diffusion limitations allow glucose to accumulate in the system.
Cannabis Phenolics and their Bioactivities
Authors: Pollastro Federica , Minassi Alberto , Fresu Luigia Grazia
Published: August 2017

Background:

Although Cannabis sativa L. is one of the most versatile plant species with
multipurpose use both as medical, alimentary source and as psychoactive abuse, its biomedical relevance
focused the attention on major cannabinoids. Phytochemical characterization of cannabis highlights
the presence of various non-cannabinoids constituents including flavonoids, spiroindans, dihyrostilbenes,
dihydrophenanthrenes, lignanamides, steroids and alkaloids. This review aims to identify
polyphenols present in this plant, their biosynthesis, their bioactivities and their synthesis, when this
occurred.

Methods:

We undertook a systematic research focused on bibliographic databases including all noncannabinoids
phenolics in various C. sativa strains from their isolation, structural elucidation, their biological
activity to their synthesis.

Result:

Nevertheless, attention has so far been focused only on cannabinoids (more than one hundred
isolated), cannabis is a complex plant able to produce more than 480 chemical entities that represent
almost all of the different biogenetic classes. Regarding phenolic compounds, the plant biosynthesises a
plethora of unique non-cannabinoids second metabolites, such as prenylated flavonoids, stilbenoids derivatives
and lignanammides.

Conclusion:

Cannabis is a plant with high pharmacological and nutrition values, its potentialities and
applications are not only circumscribed to cannabinoids biological activities, but also defined by noncannabinoid
compounds. The combination of other cannabinoids together with noncannabinoid components
could enhance the beneficial effects of THC and could reduce undesirable side effects.

Published: August 2017

Background and objectives

Post-transplant lymphoproliferative disorders arising after kidney transplantation portend an increased risk of morbidity and mortality. Retransplantation of patients who had developed post-transplant lymphoproliferative disorder remains questionable owing to the potential risks of recurrence when immunosuppression is reintroduced. Here, we investigated the feasibility of kidney retransplantation after the development of post-transplant lymphoproliferative disorder.

Design, setting, participants, & measurements

We reviewed the data from all patients who underwent kidney retransplantation after post-transplant lymphoproliferative disorder in all adult kidney transplantation centers in France between 1998 and 2015.

Results

We identified a total of 52 patients with kidney transplants who underwent 55 retransplantations after post-transplant lymphoproliferative disorder. The delay from post-transplant lymphoproliferative disorder to retransplantation was 100±44 months (28–224); 98% of patients were Epstein–Barr virus seropositive at the time of retransplantation. Induction therapy for retransplantation was used in 48 patients (i.e., 17 [31%] patients received thymoglobulin, and 31 [57%] patients received IL-2 receptor antagonists). Six patients were also treated with rituximab, and 53% of the patients received an antiviral drug. The association of calcineurin inhibitors, mycophenolate mofetil, and steroids was the most common maintenance immunosuppression regimen. Nine patients were switched from a calcineurin inhibitor to a mammalian target of rapamycin inhibitor. One patient developed post-transplant lymphoproliferative disorder recurrence at 24 months after retransplantation, whereas post-transplant lymphoproliferative disorder did not recur in 51 patients.

Conclusions

The recurrence of post-transplant lymphoproliferative disorder among patients who underwent retransplantation in France is a rare event.
Study on Three Positions Framing Kindergarten Play-Based Curriculum in China: Through Analyses of the Attitudes of Teachers to Early Linguistic Education
Authors: Peng Qian
Published: August 2017

Since 2001, there is a hot debate on Curriculum Reform of Elementary Education (CRED) in China which is called a debate between Child-centered and Rationalism. The policies of CRED adovates play-based model and since 2017 focuses on Chinese traditional culture learning. However, some people believe play is opposed to linguistic education and the moon in the west is more round than in China. Operating in the paradoxes, Chinese kindergarten teachers always are faced with dilemmas: should the teacher obey the government’s guidance, or satisfy parents’ English learning preference and literacy readiness oriented requirements? Few studies have examined how Chinese kindergarten teachers struggled for early literacy and linguistic education. In this article we examined twenty teachers’ understandings on play-based curriculum and play-literacy relationships. Comparing with the two popular positions toward Chinese play-based linguistic curriculum reforms, Chinese kindergarten teachers tend to hold a golden means. With the professional development of the kindergarten teacher, education approaches in Chinese kindergarten education based on play and local cultures will be used more often and more extensively. Under such circumstances, the English teaching and learning at the kindergarten level is also believed very important to cultivate global citizens and Chinese national citizens.

Pork is the most consumed meat in the world, in Brazil it loses only to beef and chicken meat, and the meat market has become increasingly demanding as to the quality and origin of the animals consumed mainly in questions Well-being in which these animals were produced. Much of the pig production systems have been adapting and specializing with emphasis on animal welfare, and production must present an "ethical quality" in which pork, in addition to the current quality attributes, is also presented as a native food Of animals that were raised, managed and slaughtered in a system that promotes their well-being. It is known that pre-slaughter management is of paramount importance in the pig production chain, since this stage has a direct influence on the final quality of the meat. In addition, consumers are demanding better quality products that do not harm the environment, causing farmers to invest in methods that prioritize animal welfare. In order to have a better quality of the meat, all the people involved in the pig production chain must be committed to caring for animal health and welfare, avoiding that the animals go through unnecessary suffering. The objective of this study was to review the welfare and management of pre-slaughter pigs, since Brazilian pig farms have been improving in this aspect. Proper pre-slaughter management also adds value to the final product, satisfying consumers more and more.

The megacolon is an expansion in light in the colon, with dysfunction of the smooth muscles, leading to the retention of feces. This can be caused by physical traumas, metabolic disorders, neurological, behavioral, by endocrinopathies or being idiopathic. When idiopathic it affects animals in average of 5 years of age; that will present display, aquesia, tenesmus, anorexia, vomit, slimming and apathy. The definitive diagnosis is made with abdominal radiography. Treatment may be conservative or surgical, this through colectomy total or partial colectomy. The present work reports the case of a male, feline, castrated 22 year, with a history of recurrent constipation and idiopathic megacolon. This was performed surgically with total colectomy technique, which presented good results as a treatment.
Quantum algorithms for graph connectivity and formula evaluation
Authors: Jeffery Stacey , Kimmel Shelby
Published: August 2017

We give a new upper bound on the quantum query complexity of decidingst-connectivity on certain classes of planar graphs, and show the bound is sometimes exponentially better than previous results. We then show Boolean formula evaluation reduces to deciding connectivity on just such a class of graphs. Applying the algorithm forst-connectivity to Boolean formula evaluation problems, we match theO(N)bound on the quantum query complexity of evaluating formulas onNvariables, give a quadratic speed-up over the classical query complexity of a certain class of promise Boolean formulas, and show this approach can yield superpolynomial quantum/classical separations. These results indicate that thisst-connectivity-based approach may be the "right" way of looking at quantum algorithms for formula evaluation.

A pesquisa baseada em design (DBR) envolve uma nova metodologia intervencionista que busca aliar aspectos teóricos da pesquisa em educação com a prática educacional. Na área de pesquisa em ensino de ciências, a DBR tem sido usada para planejar, implementar e avaliar sequências de ensino-aprendizagem (TLS) de conteúdos específicos. No presente artigo, apresentamos um quadro geral sobre a DBR e as TLS, descrevendo a metodologia envolvida. A partir de um olhar sobre a literatura disponível, entendemos que a metodologia DBR e os estudos envolvendo TLS são abordagens que podem contribuir com a construção e consolidação de conhecimentos didáticos específicos, ou mesmo mais gerais, relacionados com a prática docente e os processos de ensino e aprendizagem em sala de aula.
SENTIDOS DE EDUCAÇÃO AMBIENTAL MOBILIZADOS EM DISCURSOS DE PROFESSORES DE ESCOLAS ENVOLVIDOS NA FORMAÇÃO DE LICENCIANDOS EM CIÊNCIAS BIOLÓGICAS
Authors: Pasin Elizabeth Bozoti , Bozelli Reinaldo Luiz
Published: August 2017

Apesar de destacada em documentos legislativos, as escolas habitualmente abordam a Educação Ambiental (EA) de forma fragmentada e pouco consolidada. A formação inicial e continuada dos professores tem influência sobre esse panorama. Nosso objetivo foi interpretar os sentidos sobre EA, sobre a formação docente para a EA e sobre as ações em EA nas escolas mobilizados em discursos dos professores de instituições do Ensino Básico onde estagiavam licenciandos de Ciências Biológicas. Aplicamos questionários semiestruturados e nos embasamos no referencial teórico-metodológico da Análise de Discurso de linha francesa. Como resultados, observamos pequena diversidade de sentidos em relação à EA, com uma hegemonia daqueles relacionados à mudança de hábitos para preservar recursos, de EA para conservação e de EA restrita a aspectos biológicos. Alguns participantes também apresentaram uma hibridização entre EA e ensino de Ecologia. Nos discursos dos professores, as ações e discussões relacionadas à temática nas escolas são pontuais e pouco sistematizadas, carecendo de abordagens interdisciplinares, assim como se deu na formação inicial e continuada da maioria. Concluímos propondo o estabelecimento de uma relação mais orgânica entre escola e universidade, com ampliação de tempos e espaços para interações, incluindo reflexões e pesquisas coletivas que favoreçam a compreensão da constituição e mobilização de sentidos sobre a temática e problematizem seus reflexos no fazer docente.

CONCEPÇÕES DE PROFESSORES DE FÍSICA SOBRE ENSINO-APRENDIZAGEM E SEU PROCESSO DE FORMAÇÃO: UM ESTUDO DE CASO
Authors: Garcia Isabel Krey , Pozo Juan Ignácio
Published: August 2017

Neste trabalho nos propomos a investigar as concepções sobre ensino-aprendizagem de 4 professores em formação e como estas podem estar relacionadas com sua formação. Para isso foram utilizados um questionário de dilemas e uma entrevista, que abordaram diversas categorias. As concepções foram analisadas a partir do referencial teórico das Teorias Implícitas, de Pozo et al.(2006), que admite três perfis: direto, interpretativo e construtivo. As concepções apresentadas pelos professores em cada categoria foram classificadas como pertencentes a um destes perfis. Como resultado, obtivemos que a maioria das concepções dos professores apresentadas no questionário de dilemas se encaixa no perfil construtivo, mas a maioria dos extratos das entrevistas se encaixa no perfil interpretativo. Tal resultado está de acordo com pesquisas anteriores e demonstra que os professores podem escolher concepções mais avançadas do que em suas reflexões sobre a prática, ou seja, os professores demonstram ter conhecimentos teóricos, mas não parecem ser capazes de converter tais conhecimentos em reflexões sobre esta prática. Além disso, as categorias avaliação e experimental foram as que mais apresentaram extratos das entrevistas que se encaixaram no perfil direto. Algumas implicações para a formação inicial e continuada são discutidas.

Published: August 2017

Las hidrazonas son un grupo de compuestos que han cautivado a muchos investigadores por su particular estructura >C=N-N<, en donde la presencia de dos átomos de Nitrógeno diferentes crea un ambiente de alta densidad electrónica. Esto último, aunado a los sustituyentes que posea la molécula, las posibilita para tener actividades biológicas muy distintas. Las hidrazonas con estructuras aromáticas, poseen actividades antitumorales, antimicrobianas, así como anticonvulsivantes o antituberculosas. En la actualidad existen numerosas enfermedades que cobran muchas vidas a nivel mundial, por ello es necesario continuar con la búsqueda de nuevos fármacos. Debido a que muchos de los utilizados tienen efectos colaterales no deseables, se busca introducir nuevos tratamientos perfeccionados. Como ejemplo, existen fármacos que tienen actividades biológicas disminuidas, así que es posible sintetizar compuestos donde se potencialice su actividad biológica y/o se aumente su selectividad.En este sentido, los derivados de hidrazonas tienen actividades biológicas muy prometedoras, por ello se plantea este proyecto, que consiste en sintetizar, purificar y caracterizar compuestos tipo hidrazona con estructuras nuevas para posteriormente evaluar su actividad en líneas celulares específicas.El objetivo de este trabajo es la síntesis verde, purificación y caracterización de la hidrazona que lleva el nombre de (E)-10-(2,2-difenilhidrazono)fenantren-9(10H)-ona. La espectroscopia de IR, RMN y EM realizada a la hidrazona sintetizada concuerda con la estructura propuesta.

Habitually, control of biological fouling includes application of paints containing toxic substances that end upcontaminating marine ecosystem. Many organisms prevent settlement of other species synthesizing secondarymetabolites that could be used in the elaboration of environmentally friendly anti-fouling paints. This work evaluated the behavior of anti-fouling paints based on extracts from marine invertebrates in the ColombianCaribbean: Agelas tubulata, Myrmekioderma gyroderma, Oceanapia peltata, Aplysina lacunosa, Neopetrosia próxima,and Holothuria glaberrima. The painted panels were submerged in the port of Mar del Plata (Argentina); after 90 days in the sea signi!cant differences were registered in the total coverage between the painted panels andthe controls (p<0.05). The results obtained represent important progress toward using natural compounds incontrolling encrustations.

Designing for the Gap: The space between the OPV and the Frigate
Authors: Kimber Andy
Published: August 2017

One of the enduring struggles for the warship designer has been the design of the affordable warship; a ship that offers useful military capability at a fixed and ideally lower price than a pure frigate or destroyer type. BMT has been investigating this design space, through the creation of a patrol ship design called the “Venator 110”, using a variety of tools to measure performance rapidly. A capability modelling tool has been developed to rapidly compare how different designs achieve military roles and how modular systems may be used to enhance a platform. Investigations have also focused on exploring methods of achieving pragmatic enhancements to survivability. These draw on the company’s experience in developing naval and auxiliary ships which use a mix of naval and commercial equipment and practises to “tailor” survivability. Finally, design solutions that offer maximum flexibility have been incorporated within the design to explore their practicality.
Cost estimation and cost risk analysis in early design stages of naval projects
Authors: Rudíus Michael
Published: August 2017

During the design and engineering process for naval projects a comprehensive cost management is required. The overall aim is to ensure the financial feasibility throughout the project with a low financial risk. Cost management combines acquisition costs and in-service costs in order to obtain life cycle costs. In this context methods for cost estimation have to be adapted to the phase of the planning process of a naval vessel. This paper introduces challenges and solutions for the cost estimation in general and describes MTGÅLs cost estimation approach for conceptual and preliminary designs. Additionally the utilization of cost risk analyses in order to ensure a reliable budget planning and the identification of cost risk drivers will be described.

Their particular area of proliferation is the short sea shipping where their power, economy, habitability and behavior have provided them a market niche. The rapid market growth ha caused catamarans to experience design modifications regarding size, speed, cargo diversity (passengers, vehicles, containers). The purpose of this article is to show the work developed by the El Pardo Hydrodynamic Experiences Channel (CEHIPAR) regarding the propulsive qualities of catamaran vessels. This work is the result of the need expressed by the Ministry of Defense for provision of technical assistance and scientific research for an I+D program that established more adequate program parameters for a catamaran-type vessel from the propulsive point of view, in relation to its size and shape, so that it has the adequate information and trustworthiness when suggesting a vessel of this type as an alternative to other platforms, always within the scope of application of patrol-type or quick-attack-type vessels.

Published: August 2017

Smoothed particle hydrodynamics (SPH) is a meshless, Lagrangian CFD method. SPH often utilizes static virtual particles to correct for integral deficiencies that occur near boundaries. These virtual particles, while useful in most cases, can be difficult to implement for objects which experience large deformations. As an alternative to virtual particles, a repulsive force algorithm is presented which loosely emulates the presence of virtual particles in the SPH momentum equation.

Metamodels, also known as surrogate models, can be used in place of computationally expensive simulation models to increase computational efficiency for the purposes of design optimization or design space exploration. Metamodel-based design optimization is especially advantageous for ship design problems that require either computationally expensive simulations or costly physical experiments. In this paper, three metamodeling methods are evaluated with respect to their capabilities for modeling highly nonlinear, multimodal functions with incrementally increasing numbers of independent variables. Methods analyzed include kriging, radial basis functions (RBF), and support vector regression (SVR). Each metamodeling technique is used to model a set of single-output functions with dimensionality ranging from one to ten independent variables and modality ranging from one to twenty local maxima. The number of points used to train the models is increased until a predetermined error threshold is met. Results show that each of the three methods has its own distinct advantages.
Passenger submarine concept design for oil production offshore systems
Authors: Lobão de Almeida Thiago , Coracini Tonacio Victor
Published: August 2017

The paper proposes an innovative solution to transport workers of offshore oil production platforms from the coast to their units, which operate at the Pre-Salt exploration, 300 km from the coast. A passenger submarine concept design was developed, justified by the range of practical obstacles observed in the current modes of transportation, helicopters and supply boats. Requirements like operational depth (100 m), passenger capacity (250 people), and cruising speed (minimum 13.4 knots) are defined, based on estimates. Firstly, it seeks the adoption of air-independent propulsion (AIP) systems, by fuel cells (PEMFC). However, the work progress leads to an entire electric propulsion system. The internal arrangement is elaborated, regarding passenger comfort, structural constraints, allocation of batteries and ballast tanks. Then, after a hydrodynamic hull optimization, by Computational Fluid Dynamics analysis, we provide a final configuration with 100-m length and 9.7-m diameter, operational speed of 16 kt, and autonomy of 26 hours.
Aid in the design of antenna arrays with electronic phase steering using Matlab®
Authors: Gil Navia Francisco José
Published: August 2017

Antenna arrays have been used since the 1950s in multiple applications; however, it was not until recent years that, given progress in digital technologies, this application has become the fastest and most varied development in the radar world. The main motivation for their development is that they permit electronic phase steering that implies extreme phase agility, while also being tolerant to failure because of the amount of elements that comprise them. They also permit the reduction of side lobes by controlling the amplitude of each element.Because it is a currently applied technology, but with many aspects under development, it is necessary to enter this field and generate the required tools including those for computer assisted prototyping. Because of the aforementioned, this work sought to use Matlab® to create virtual prototypes of arrays that permit visualizing an approach to their real behavior stemming from certain parameters.

Recent developments in the design of fast ships

During the last twenty years, Damen Shipyards, a multinational shipbuilding group with 6000 employees worldwide, has done extensive research on the development of hull designs for fast monohull vessels. In the 1990s the Enlarged Ship Concept was developed, leading to highly improved sea keeping capabilities and vessel behaviour in waves at high speed. This hull design concept was applied in the Damen SPa 4207 patrol vessel and has proven extremely successful, reducing vertical accelerations by 50% and, thus, allowing vessels to keep operating at high speed in waves. Over 25 units of the Damen SPa 4207 have been delivered so far. After the successful introduction of the Enlarged Ship Concept, Damen and Delft University continued developing the next generation hull form: the axebow design. Compared to the already good sea keeping capacities of the Enlarged Ship Concept, model tests indicated a further reduction of vertical accelerations. This was proven by real-time measurements on the first built axebow vessels in 2006 and 2007. In the last 3 years, over 30 axe bow supply vessels have been delivered to very satisfied operators. As a next step, Damen has applied the axe bow design to the latest patrol vessel design, the Damen SPa 5009. The first vessel of this design is currently under construction and its trials are scheduled by the end of 2011. The paper describes the background of the research done by Damen and Delft University, focusing on the mathematical and scientific aspects of the axebow design and its application on various ship types. The development and design of the latest Damen patrol vessel, SPa 5009, will be introduced, describing its seakeeping performance, operatability and crew ergonomics. Finally, the paper will mention the current and future research topics that Damen and Delft University are working on together, identifying the developments of the future generation patrol vessels.
Application-optimised propulsion systems for energy-efficient operation

Published: August 2017

Today, optimal propellers are designed by using advanced numerical methods. Major revolutionary improvements cannot be expected. More essential are the design conditions and the optimal adaptation of the propulsion system according to the operational requirements. The selection and optimisation of the propulsion system based on a systematic analysis of the ship’s requirements and the operation profile are the prerequisites for reliable and energy-efficient propulsion. Solutions are presented, which accommodate these issues with a focus on steerable rudderpropellers. Considerations include the efficiency potential of the propulsor itself, optimisation of the engine propeller interaction, and optimisation of a demandresponsive energy supply. The propeller-thruster interaction is complex, but offers some potential for optimisation. Results of examinations show this. The power distribution between multiple propellers at high loads of limited propeller diameters increases the efficiency. This can be done by double-propeller systems like the SCHOTTEL TwinPropeller or by distributing the power on several thrusters. This distributed propulsion offers economic operation and an increased lifetime by means of the demandresponsive use of energy. An efficiency-optimized electric motor instead of the upper gear box reduces the mechanical losses in the case of diesel-electric propulsion. An example: the SCHOTTEL CombiDrive.
