Yacht Design Software 2.0: The Open Source Movement
Authors: Bird Mathew , Cook William F. , Hazen George S. , Ward Britton 
Published: April 2021

This paper is a survey of the current state of the art of open source software for yacht design applications.
Yacht design and design tools we use have undergone numerous transformations in recent decades, the most notable being the introduction of the personal computer. Since the advent of the PC, yacht designers have been forced to create their own programs from scratch or choosing from relatively few off-the-shelf programs. Commercial software has been characterized by high expense, closed systems, and limited interoperability between applications that are difficult to fully customize or use in a collaborative manner. A lot of sneaker-netting and custom conversion code is often required. For the last several years, users in many industries have been given a new option of joining the “open source movement,” where software and the underlying code is made available for users to download, modify, improve and again make available to others. With open source, the isolated approach to custom software development can be replaced with a broad base of core capability that can be extended and shared with the larger community. Industry players collaborate on the essential elements of tools for our profession - as the saying goes, "A rising tide will lift all boats." There is still plenty of room for individuals or companies to differentiate themselves by how they use the tools and by their niche areas of expertise or experience, but the return on investing in an 'open source' set of common tools is potentially greater than its cost. In doing so, software tools are developed and improved in a collaborative manner, resulting in shorter development time and applications that are more powerful, robust and interoperable for all users. Although working in a closed environment may feel safe and secure to private actors, the lack of adequate peer review and external contribution leads to situation specific myopia. In this paper, we will survey available open source tools both general and yacht design specific that can be used, present some suggestions on integrating them into the design process and explore how the industry can improve these tools in the future.
Alpha and Rocker - Two Design Approaches that led to the Successful Challenge for the 2007 International C-Class Catamaran Championship
Authors: Killing Steve 
Published: April 2021

In 2007 Canada entered its first challenge for the International C-Class Catamaran Championship and was victorious in capturing the trophy with five straight wins by Alpha CAN 6 over the venerable Cogito from the USA.
Two boats were designed for this challenge - the first was Alpha, a wingsail catamaran, which incorporated some new thinking on sail configuration and hull shape. This made it a successful evolutionary, but not revolutionary, step from the current state-of-the-art boats. Compared to Cogito, the main rival, she had a taller, narrower and thinner wing, lighter construction and more circular hull cross section. The second was Rocker, the bold hydrofoil catamaran, using hulls from the same mold as Alpha and an identical wingsail as the driving force. The daggerboard hydrofoils automatically controlled the ride height with trim tabs, while the control of the rudder elevators was left to the helmsman. Although she flew well, was very controllable, and was spectacular to watch, Rocker could not match the 20 knot plus speed of Alpha.

Authors: Del Prado Morales Mirtha , Alonso-Tapia Jesús , Simón Rueda Cecilia 
Published: April 2021

Este estudio tiene dos objetivos. Primero, estudiar la validez del modelo de clima motivacional de la familia como indicador de implicación parental, cuando se evalúa con el cuestionario de Clima Motivacional de la Familia para padres (CMF/P). Y, segundo, hacerlo en población española y cubana con el fin de determinar las diferencias en la percepción del CMF de los padres de ambos países. Participaron 892 padres, 400 españoles y 492 cubanos. Se realizaron análisis factoriales confirmatorios, de validez cruzada y multigrupo, y análisis de fiabilidad. Los resultados muestran, tanto en España como en Cuba, la validez del Modelo teórico que subyace al cuestionario. Las ayudas que ofrecen los padres sirviendo como ejemplo a sus hijos y la estructuración del trabajo escolar en casa por parte de los padres son los factores de mayor peso en la definición del CMF. Sin embargo, la cultura moderó la configuración del CMF en varios indicadores del Modelo, mostrando diferentes maneras de actuar entre padres españoles y cubanos en la configuración de un clima familiar motivador.

The purpose of this study is to design and evaluate how Cuban and Spanish population are validated through CMF/P-Q studies and to determine the differences in the CMF perception of the parents of both countries. Participants were 892 parents; from them, 400 Spanish and 492 Cubans. Among the most important results are: Both in Spain and in Cuba, the CMF / P-Q Questionnaire, supports the validity of the theoretical Model that underlying it. The help offered by parents as an example to their children and the structure of school work at home by parents are the most important factors in the definition of the CMF. The structure of the CMF in several indicators of the Model was moderated by the culture, distinguishing different ways of acting between Spanish and Cuban parents in an agreement of a motivating family climate.

Published: April 2021

Starting with the creation of the global information space, there are two forces that can really influence information processes. The first side is the technological side, the other side is the state structures based on social and humanitarian issues.The creators of global networks and the owners of key technologies advocate that everything remains as it is, based on freedom of speech, and in humanitarian terms, states are trying to control this process based on the implementation of legislation.The first side is based on free speech, controls the advertising market and dodges taxes, the other side wants to deal with “concerned groups” and also fight social ailments.In this confrontation, libraries, as institutions influencing the information environment, stand next to the state and try not to lose their attractiveness. In this respect, libraries can act as a bridge between local and regional as well as global networks.
Libraries, academic and university libraries currently operating in the world and meeting modern challenges are the main participants in the authoritative information cycle. Coordinating the information activities of these agencies can lead to a significant improvement in the information environment.
The main goal of the study is to identify the optimal forms and methods of using social networks in libraries. It is also exploring the reasons why libraries use social media to ensure an effective and widespread information service.

AbstractAll solid‐state batteries holds great promise for superiorly safe and high energy electrochemical energy storage. The ionic conductivity of electrolytes and its interfacial compatibility with the electrode are two critical factors in determining the electrochemical performance of all solid‐state batteries. It is a great challenge to simultaneously demonstrate fantastic ionic conductivity and compatible electrolyte/electrode interface to acquire a well‐performed all solid‐state battery. By in situ polymerizing poly(ethylene glycol) methyl ether acrylate within a self‐supported 3D porous Li‐argyrodite (Li6PS5Cl) skeleton, the two bottlenecks are tackled successfully at once. As a result, all solid‐state lithium metal batteries with a 4.5 V LiNi0.8Mn0.1Co0.1O2 cathode designed by this integrated strategy demonstrates a high Coulombic efficiency exceeding 99% at room temperature. Solid‐state nuclear magnetic resonance data suggest that Li+ mainly migrates along the continuous Li6PS5Cl phase to result in a room temperature conductivity of 4.6 × 10−4 S cm−1, which is 128 times higher than that of the corresponding polymer. Meanwhile, the inferior solid–solid electrolyte/electrode interface is integrated via in situ polymerization to lessen the interfacial resistance significantly. This study thereby provides a very promising strategy of solid electrolyte design to simultaneously meet both high ionic conductivity and good interfacial compatibility towards practical high‐energy‐density all solid‐state lithium batteries.

AbstractUltrafine nanoparticles with organic–inorganic hybridization have essential roles in myriad applications. Over the past three decades, although various efforts on the formation of organic or inorganic ultrasmall nanoparticles have been made, ultrafine organic–inorganic hybrid nanoparticles have scarcely been achieved. Herein, a family of ultrasmall hybrid nanoparticles with a monodisperse, uniform size is synthesized by a facile thermo‐kinetics‐mediated copolymer monomicelle approach. These thermo‐kinetics‐mediated monomicelles with amphiphilic ABC triblock copolymers are structurally robust due to their solidified polystyrene core, endowing them with ultrahigh thermodynamic stability, which is difficult to achieve using Pluronic surfactant‐based micelles (e.g., F127). This great stability combined with a core–shell–corona structure makes the monodispersed monomicelles a robust template for the precise synthesis of ultrasmall hybrid nanoparticles with a highly uniform size. As a demonstration, the obtained micelles/SiO2 hybrid nanoparticles display ultrafine sizes, excellent uniformity, monodispersity, and tunable structural parameters (diameters: 24–47 nm and thin shell thickness: 2.0–4.0 nm). Notably, this approach is universal for creating a variety of multifunctional ultrasmall hybrid nanostructures, involving organic/organic micelle/polymers (polydopamine) nanoparticles, organic/inorganic micelle/metal oxides (ZnO, TiO2, Fe2O3), micelle/hydroxides (Co(OH)2), micelle/noble metals (Ag), and micelle/TiO2/SiO2 hybrid composites. As a proof of concept, the ultrasmall micelle/SiO2 hybrid nanoparticles demonstrate superior toughness as biomimetic materials.

Published: April 2021

AbstractA new type of plasmonic anti‐counterfeiting labels is designed on the basis of Au@SiO2 core–shell nanoparticles (Au@SiO2 NPs) and electrospun fibers. The fingerprint information of Raman active molecules is amplified by the plasmonic Au nanoparticles, and silica layers endow the stability of encoding information. Electrospun fibers with unordered breathable structure play the role of polymer matrix and own the flexible features. Au@SiO2 NPs are first adsorbed on the surface of poly(methyl methacrylate)/poly(4‐vinylpyridine) (PMMA/P4VP) fibers by noncovalent interactions, and then are decorated in/on the fibers by controlling the temperature. That is, when the temperature is higher than the glass transition temperature (Tg) of polymer matrix, partial Au@SiO2 NPs are embedded in the PMMA/P4VP fibers. The composite fibers based on the Au@SiO2 and PMMA/P4VP fibers are fabricated, and the signals of Raman active molecules are amplified in the Au@SiO2/PMMA/P4VP fibers. The peak positions and intensity of spectra from surface‐enhanced Raman spectroscopy are transferred into plasmonic anti‐counterfeiting labels with different spaces and widths. The anti‐counterfeiting labels are further encrypted into quick response (QR) codes and decrypted by the smartphone. The QR codes are difficult to copy and easy to authenticate, and composite fibers possess superior stability and show potential application in the field of anti‐counterfeiting.

Published: April 2021

AbstractWearable electronics are becoming one of the key technologies in health care applications including health monitoring, data acquisitions, and real‐time diagnosis. The commercialization of next‐generation devices has been stymied by the lack of ultrathin, flexible, and reliable power sources. Wearable thermo‐electrochemical cells (TECs), which can convert body heat to electricity via an electrochemical process, are showing great promise as power sources for such wearable systems. TECs harvest orders of magnitude more voltage per temperature difference (Seebeck coefficient (1–34 mV K−1)) when compared to the more common thermoelectric generators (Seebeck coefficient ≈tens or hundreds of µV K−1). However, there still remain great challenges for TECs progressing towards wearable applications. This review summarizes the recent development of potentially wearable TECs with promise for body‐heat harvesting, with a specific focus on flexible electrode materials, solid‐state electrolytes, device fabrication, and strategies toward applications. It also clarifies the challenges and gives some future direction to enhance future investigations on high‐performance wearable TECs for practical and self‐powered wearable devices.

AbstractFilippi syndrome (MIM #272440), one of the craniodigital syndromes, is a rare genetic entity with autosomal recessive inheritance and characterized by pre‐ and postnatal growth retardation, microcephaly, distinctive facial appearance, developmental delay/intellectual disability, and variable syndactylies of the fingers and toes. In this report, a further female patient of Filippi syndrome who additionally had a unilateral congenital talipes equinovarus (CTEV), a feature not previously recorded, is described. Genetic testing revealed a novel homozygous frameshift pathogenic variant (c.552_555delCAAA, p.Asn184Lysfs*8) in CKAP2L and thus confirmed the diagnosis of Filippi syndrome. We hope that the newly recognized feature (CTEV) will contribute to expand the clinical spectrum of this extremely rare condition. In view of the paucity of reported cases, the full spectrum of clinical findings of Filippi syndrome necessitates obviously further affected individuals/pedigrees delineation in order to elucidate the etiological and phenotypic aspects of this orphan disease appropriately.

Production of clean hydrogen from methane decomposition over molten NiO‐LiOH catalyst systems supported on CaO: Synergistic effect of molten LiOH on catalyst activity
Authors: Musamali Ronald W. , Isa Yusuf M. 
Published: April 2021

AbstractMature hydrogen producing technologies like steam methane reforming, coal combustion, and hydrogenation of hydrocarbons are leading emitters of greenhouse gases into the atmosphere. Catalytic decomposition of methane into carbon and hydrogen is a sure way of controlling the net emission of this greenhouse gas into the atmosphere. In this study, we present an environmentally benign approach of producing hydrogen from methane over a supported molten metal oxide catalyst. Catalyst systems were prepared by incipient wetness impregnation and characterized for crystallinity, shape and size, and surface area using various techniques. Methane conversion experiments were done in a packed bed reactor over three different catalyst systems synthesized from nickel oxide, lithium hydroxide, and calcium oxide (CaO) under various process conditions. Gaseous products from the reactor were analyzed using gas chromatography. Using catalyst 38N12L, 45.9% hydrogen yield was obtained at 650°C and GHSV of 1.2 Lg−1cath−1. The molten environment provided by LiOH enhanced hydrogen yields by 12.6% through surface reaction and chemisorption. Calcium oxide played a bifunctional role as a catalyst support and an adsorbent of in situ generated CO/CO2 gases thereby improving hydrogen quality.

AbstractAnion exchange resins are widely used in template synthesis of oxide composites. The present work is aimed to study the thermal destruction of anion exchangers with divinyl‐benzene and polyacrylate matrices in order to obtain hollow spherical MoO3/TiO2–SiO2 composites from these resins preliminarily saturated with paramolybate ion and coated with tetrabutoxytitanium sol with tetroethoxysilane. It is shown that the processes of resins decomposition affect the strength of spherical composites. Decomposition of the resin with a polyacrylate matrix, accompanied by random nucleation and burnout of the organic matrix at 350°C, leads to the formation of spherical oxide composites with cracks on the surface. The decomposition reactions of the resin with a divinylbenzene matrix occurring at the boundaries of the phases of cylindrical and spherical symmetry, as well as a lower burnout temperature of the organic matrix (290°C), contribute to the formation of dense MoO3/TiO2–SiO2 spheres. Hollow spherical composites 0.3–0.5 mm in size are orthorhombic α‐MoO3 coated with a mixture of titanium dioxide with anatase structure and amorphous silicon dioxide.
