Full textAbstract:
The main advantage of the Wang tiling concept for material engineering is ability to create large material domains with a relatively small set of tiles. Such idea allows both a reduction of computational demands and preserving heterogeneity of a reconstructed media in comparison with traditional cell concepts. This work is dealing with a random heterogeneous material composed of monodisperse circular hard particles within a matrix. The Wang tile sets are generated via algorithm with molecular dynamics and adaptive boundaries approach. Even though previous works proved usefulness of the Wang tiling for material reconstruction, still plenty of questions remain unanswered. In here we would like to provide simulations with emphasis on the overall particle distribution and the ratio of hard disc number to tile size. The results and discussion should followers help with settings of both tile generations and the tiling algorithms when creating samples of various degree of heterogeneity.

ObjectivesThe primary objective of this paper was to independently evaluate the currently available web-based software options for virtual consultations in a secondary care setting.DesignComparative study.SettingUK.ParticipantsWeb-based software options for virtual consultations in a secondary care setting.Main outcome measuresEight predetermined measures of functionality were assessed including time to setup, availability of a diary system, ability to book appointments in advance, ability to send patient reminders, ability to add a second caller, text messaging functionality, need for the patient to download an app and web browser compatibility.ResultsNine platforms met the inclusion criteria for web-based standalone video consultation solutions. Four offered immediate access via an nhs.net email address. Six platforms used an appointment diary system, with five allowing clinicians to see which patients were ready and waiting for consultation at any particular time. Four of the platforms had the facility to book appointments in advance and send appointment details via text message or email. Five of the platforms had the ability to add a second caller. One platform required the patient to download a mobile phone app. All platforms were compatible with Google Chrome, Safari, Firefox and Microsoft Edge (Chromium or Blink versions).ConclusionsThe uptake of virtual online consultations has been accelerated by the COVID-19 pandemic and the National Health Service (NHS) has become a forced ‘early-adopter’. Many of the solutions do well to address the demand; however, more work is required for it to be embedded into routine service and fulfil the aims of the NHS Long Term Plan: allow patients more choice and flexibility in their care. It is vital that once normality resumes, research focuses on the outcomes of virtual online consultations, with focus on factors such as patient satisfaction, length of appointment, time to diagnosis and initiation of management.

Full textAbstract:
The continuous rheoconversion process (CRPTM) is a novel slurry-on-demand process that was developed at MPI/WPI in 2002. The process is based on a passive liquid mixing technique in which the nucleation and growth of the primary phase are controlled using a specially designed “reactor”. The reactor provides heat extraction, copious nucleation, and forced convection during the initial stage of solidification, thus leading to the formation of globular structures. This paper presents our recent work on the scale-up of the CRPTM for industrial applications. In Part II of this paper, we present salient results on alloy optimization via thermodynamic simulations, as well as validation results obtained from industrial Beta trials.

89 Background: The number of cancer survivors in the United States is expected to approach 22 million by the year 2029. With an annual Survivorship Program visit volume exceeding 16,000, this comprehensive cancer center developed an innovative approach to delivering survivorship care to meet the growing demand for comprehensive follow up care. Institutional space, patient convenience and visit compliance are also factors in considering alternatives to traditional ‘brick and mortar’ visits. Methods: Patients are seen in our Autologous Bone Marrow Transplant (BMT) Survivorship Clinic at 6, 12- and 24-months post-transplant. A pilot was developed targeting patients scheduled for a 6-month visit, where patients are often struggling with treatment sequelae, managing other medical appointments, and returning to work and life after transplant. Patients were offered a telemedicine visit instead of an in-person clinic visit with the survivorship advanced practice provider (APP). The Survivorship APP and administrative staff were trained on the use of monitors and technologic means to connect patient to provider. Eligible patients had to have an institutional portal account and speak English. They were contacted by phone to assess interest, and if they agreed, instructions were provided via secure institutional portal reviewing device and connectivity requirements. Results: The telemedicine visit components included: review of home medication list, interval history and review of systems, screen for late treatment effects, lab result review, treatment summary and care plan review including risk of secondary cancer and screening recommendations, health promotion counseling, primary care physician recommendations and immunization status. Of 26 visits scheduled, 22 were successfully completed. Challenges to completing the visit will be described and include poor connectivity and patient location at the time of the scheduled visit. Conclusions: Despite some minor challenges, patients described good satisfaction with telemedicine citing visit comprehensiveness and convenience. As a result of the successful pilot, telemedicine visits are being expanded to include survivorship patients who are 24 months post BMT.

 Abstract 
 
 Objective – To examine the attitudes and information behaviours of early career researchers (ECRs) when locating scholarly information. 
 
 Design – Qualitative longitudinal study.
 
 Setting – Research participants from the United Kingdom, United States of America, China, France, Malaysia, Poland, and Spain.
 
 Subjects – A total 116 participants from various disciplines, aged 35 and younger, who were holding or had previously held a research position, but not in a tenured position. All participants held a doctorate or were in the process of earning one.
 
 Methods – Using structured interviews of 60-90 minutes, researchers asked 60 questions of each participant via face-to-face, Skype, or telephone interviews. The interview format and questions were formed via focus groups. 
 
 Main Results – As part of a longitudinal project, results reported are limited to the first year of the study, and focused on three primary questions identified by the authors: where do ECRs find scholarly information, whether they use their smartphones to locate and read scholarly information, and what social media do they use to find scholarly information. Researchers describe how ECRs themselves interpreted the phrase scholarly information to primarily mean journal articles, while the researchers themselves had a much expanded definition to include professional and “scholarly contacts, ideas, and data” (p. 22). 
 
 This research shows that Google and Google Scholar are widely used by ECRs for locating scholarly information regardless of discipline, language, or geography. Their analysis by country points to currency and the combined breadth-and-depth search experience that Google provides as prime reasons for the popularity of Google and Google Scholar. Of particular interest is the popularity and use of Google Scholar in China, where it is officially blocked but accessed by ECRs via proxy services. Other general indexes, such as Web of Science and Scopus, are also popular but not universally used by ECRs, and regional differences again point to pros and cons of these services. Some specialized services are emphasized, including regional tools such as the China National Knowledge Infrastructure, as well as certain broad disciplinary resources, such as PubMed for its coverage of sciences and biomedical information. 
 
 Researchers report that ECRs participating in this study were less concerned about how they gained access to full-text scholarly information, only that they could access full-text sources. In particular, ECRs do not take much notice of libraries and their platforms, seemingly unaware of the steps libraries take to acquire and ensure access to scholarly information, while viewing physical libraries themselves primarily as study spaces for undergraduate students and not places for the ECR to visit or work. While ECRs occasionally acknowledge library portals and login interfaces, researchers found that these participants mostly ignored these, and that they found discovery services to be confusing or difficult. 
 
 Concerning social media use, participants identified 11 different platforms used but only ResearchGate was mentioned and used by participants from all seven countries represented. Social media tends to be used directly for keeping track of research trends and opinions and also the work specific researchers are publishing, and indirectly when referred to sites such as ResearchGate to find full-text of a specific article. Facebook, Twitter, and LinkedIn are used occasionally or moderately, but not universally. Researchers highlight regional differences of social media use in China, where ECRs are more likely to connect with other researchers and receive notifications when those researchers publish.
 
 The study reports limited information ECRs’ use of smartphones for information seeking. About half of ECR participants reported use of their smartphone for discovering scholarly sources. The advantage smartphones provide includes near-ubiquitous Internet access and therefore the ability to access scholarly materials on the go, though ECRs are less likely to download or read full-text articles via their smartphones. The rate of adoption of smartphone use for scholarly materials varies by country. 
 
 Conclusion – Early career researchers access scholarly information in a wide variety of ways, with Google and Google Scholar as the preferred starting location, and with social media also proving useful. Ease-of-use and full-text availability are paramount concerns; the spread of open access materials helps fuel the availability of materials, and Google makes these easy to find. Though physical libraries are perceived to be of limited use, the digital access they provide to full-text scholarly sources is still vital even if ECRs do not make the connection between having that important access and the fact that libraries act as buyers and providers of access

Full textAbstract:
This paper summarizes several years of Traffic Flow Management (TFM) R&D work. The MITRE Corporation's Center for Advanced Aviation System Development (CAASD) has been engaged in a longterm research program to define and refine decision support concepts and capabilities for TFM, the branch of Air Traffic Management that manages the strategic aspect of air traffic by balancing airspace capacity with demand, especially during severe weather or heavy traffic. This paper describes CAASD's work on the concept of Collaborative Routing, in which all affected parties — Federal Aviation Administration (FAA) and aircraft operators - can share in realtime a common picture of TFM problems and potential solutions. The Collaborative Routing Coordination Tools (CRCT) refers to a set of functionalities that support Collaborative Routing, and also to a software platform developed and used by CAASD to conduct the R&D. In this paper, the Collaborative Routing concept is described, and sample user interfaces supporting the concept are presented. Evaluations with operational personnel are described at a high level. Capabilities developed and refined via this work include the FCA (Flow Constrained Area), and the reroute modeling capability. These functions allow the user to evaluate the impact of a rerouting solution to controllers and airspace users (airlines and other pilots), before implementing that solution. Finally, ongoing research on future TFM decision support capabilities is described.

Full textAbstract:
Abstract Introduction Despite the high co-occurrence of sleep and mood disturbances, day-to-day associations between sleep characteristics (sleep duration, continuity, timing) and dimensions of mood (positive affect, PA, and negative affect, NA) remain unclear. Few field studies have tested whether sleep changes may affect mood by altering people’s emotional response to daily experiences outside the laboratory. The current study aimed to examine how sleep characteristics influence affective states and a measure of emotional response to daily experiences—affect reactivity. Methods Participants were healthy, midlife adults (30–54 yrs old, N =462, 47% male) drawn from the Adult Health and Behavior Project- Phase 2 study. Sleep was measured with actigraphy across a 4-day monitoring period; hourly self-report measures of affect, work demand, and social interactions were collected via ecological momentary assessment. Affect reactivity was quantified as hour-to-hour changes in affect following these daily experiences. We used hierarchical linear modeling to examine whether sleep characteristics on a given night predicted average daily affect and moderated affect reactivity the following day. Results When participants slept later than their average sleep time on a given night, they reported greater NA the following morning (before 12pm) and afternoon (12-6pm; B’s =.03, p’s<.05). When participants slept longer than their average sleep duration, they subsequently reported greater NA throughout the following day (B’s =.02, p’s<.05). Sleep efficiency was unrelated to affect report (p’s >.05). While episodes of greater work demand and social conflict predicted lower PA and higher NA (p’s<.05), participants’ sleep characteristics did not moderate these associations (p’s>.05). Conclusion Overall, our findings suggest proximal associations between sleep characteristics and next-day mood. While previous studies have shown effects of sleep disruptions on affect reactivity, we did not observe such associations in the context of small, day-to-day fluctuations in sleep characteristics among healthy individuals.

Full textAbstract:
A literature review and gap analysis indentifies key limitations of industry best practice when modelling of supply chains. To address these limitations the paper reports on the conception and development of an integrated modelling methodology designed to underpin the analytical design of complex supply chains. The methodology is based upon a systematic deployment of EM, CLD, and SM techniques; the integration of which is achieved via common modelling concepts and decomposition principles. Thereby the methodology facilitates: (i) graphical representation and description of key “processing”, “resourcing” and “work flow” properties of supply chain configurations; (ii) behavioural exploration of currently configured supply chains, to facilitate reasoning about uncertain demand impacts on supply, make, delivery, and return processes; (iii) predictive quantification about relative performances of alternative complex supply chain configurations, including risk assessments. Guidelines for the application of each step of the methodology are described. Also described are recommended data collection methods and expected modelling outcomes for each step. The methodology is being extensively case tested to quantify potential benefits & costs relative to current best industry practice. The paper reflects on preliminary benefits gained during industry based case study modelling and identifies areas of potential improvement.

Full textAbstract:
Living cells obtain energy either by oxidizing reduced compounds of organic or mineral origin or by absorbing light. Whichever energy source is used, some of the energy released is conserved by converting adenosine diphosphate (ADP) to adenosine triphosphate (ATP), which are analogous to the chemicals in a rechargeable battery. The energy released by the conversion of ATP back to ADP is used to drive most energy-requiring processes, including cell growth, cell division, communication and movement. It is clearly essential to life that the production and consumption of ATP are always maintained in balance, and the AMP-activated protein kinase (AMPK) is one of the key cellular regulatory systems that ensures this. In eukaryotic cells (cells with nuclei and other internal membrane-bound structures, including human cells), most ATP is produced in mitochondria, which are thought to have been derived by the engulfment of oxidative bacteria by a host cell not previously able to use molecular oxygen. AMPK is activated by increasing AMP or ADP (AMP being generated from ADP whenever ADP rises) coupled with falling ATP. Relatives of AMPK are found in essentially all eukaryotes, and it may have evolved to allow the host cell to monitor the output of the newly acquired mitochondria and step their ATP production up or down according to the demand. Structural studies have illuminated how AMPK achieves the task of detecting small changes in AMP and ADP, despite the presence of much higher concentrations of ATP. Recently, it has been shown that AMPK can also sense the availability of glucose, the primary carbon source for most eukaryotic cells, via a mechanism independent of changes in AMP or ADP. Once activated by energy imbalance or glucose lack, AMPK modifies many target proteins by transferring phosphate groups to them from ATP. By this means, numerous ATP-producing processes are switched on (including the production of new mitochondria) and ATP-consuming processes are switched off, thus restoring energy homeostasis. Drugs that modulate AMPK have great potential in the treatment of metabolic disorders such as obesity and Type 2 diabetes, and even cancer. Indeed, some existing drugs such as metformin and aspirin, which were derived from traditional herbal remedies, appear to work, in part, by activating AMPK.

preenchimento on-line de questionários individuais.
Através da análise das dezasseis hipóteses colocadas, foi possível apurar que as
exigências laborais agem como stressors organizacionais, condicionam
comportamentos e emoções no local de trabalho, afectam o bem-estar psicológico e
organizacional, e só os recursos (tanto laborais como pessoais) podem devolver algum

the labor contexts have became more demanding. We looked to ascertain the effect of
labor demands in psychological, emotional and behavioral repercussions, and what part
do labor and personal resources play in these relations. Why do some individuals face
these work contexts as demanding while others look at them as challenging?
Considering a sample of two hundred working individuals, from both genders,
diverse sectors and professional categories, different ages and academic backgrounds,
and with various contractual links, all answers were obtained through individual
questionnaires filled online.
By analyzing all the sixteen hypotheses placed, it was possible to investigate that
labor demands act as organizational stressors, conditioning behaviors and emotions at
the workplace, affecting the psychological and organizational well-being, and only the
resources (both labor and personal) may return some balance to these relations. These
resources have demonstrated to play an important motivational role while attenuating
the effects of the occupational stress.

This book examines in detail the legal implications of cloud computing. In essence, 'the cloud' is a way of delivering computing resources as a utility service via the Internet. It is evolving very rapidly with substantial investments being made in infrastructure, platforms, and applications, all delivered 'as a service'. The demand for cloud resources is enormous, driven by such developments as the deployment on a vast scale of mobile apps and the rapid emergence of 'Big Data'. The book explains what cloud computing is and how it works; analyses contractual relationships between cloud service providers and their customers, as well as the complex roles of intermediaries; and explores specific arrangements for public sector cloud procurement and questions about ownership of data in clouds. It also studies the protection of personal data in clouds, governance challenges relating to access to data in clouds by law enforcement authorities, ways of facilitating competition between cloud service providers, and the consumer protection implications of cloud computing.

Full textAbstract:
Acute respiratory failure not only impairs gas exchange, but also stresses cardiovascular reserve by increasing the need for increased cardiac output (CO) to sustain O2 delivery in the face of hypoxaemia, increased O2 demand by the increased work of breathing and inefficient gas exchange, and increased right ventricular afterload due to lung collapse via hypoxic pulmonary vasoconstriction. Mechanical ventilation, though often reversing these processes by lung recruitment and improved arterial oxygenation, may also decrease CO by increasing right atrial pressure by either increasing intrathoracic pressure or lung over-distention by excess positive end-expiratory pressure or inadequate expiratory time causing acute cor pulmonale. Finally, spontaneous negative swings in intrathoracic pressure also increase venous return and impede left ventricular ejection thus increasing intrathoracic blood volume and often precipitating or worsening hydrostatic pulmonary oedema. Positive-pressure breathing has the opposite effects.

Full textAbstract:
The demand for meat grew in Western Europe after World War II: meat became a mass-product from the 70s of the last century onwards. However, while in the consumer product section “brands” were established, in the agricultural sector food was an anonymous product. Unfortunately, mass-production and discount-prices resulted in many food scandals starting in the 80s. In the beef-sector, especially the British Cow Decease (BSE) created a mistrust of meat. To re-gain “trust” meat-buyers of six German retail-chains started in 1995, together with the Cologne-based EHI Retail Institute, a tracking and tracing system—known later as the EHI-Meat-Label. This private initiative has been rolled out since 1997 by the EU via EU-regulations. Within the last five years, most stakeholders had been built up in the total supply chain in Western Europe with tracking/tracing systems from farm to fork, quite often with the help of IT. The evolution at the beginning of this decade is caused by mobile technology and social media, i.e. apps on smart phones that enable the communication “from fork to farm.” The challenge is a U-turn of info-streams strongly emphasizing consumer awareness. Part one of this chapter discloses what had happened at the backstage of the EHI-Meat Workshop between 1994 and 2001 to create a technical tool for tracing, to intertwine all stakeholders in the market, and to establish politics, both nationally and internationally. This work represents a case study of applied sciences to explain chronologically what happened within that time-period. Part two is an analysis of the marketing-tools and how the mix of the activities of EHI was used so that this success-story could unfold. Part three is a look at how to cope with the new challenge of smart phones and apps by integrating the individual pioneers into an EU-roof of Future Internet and Technologies. The chapter has been developed through an ethnographic observation platform by the author’s practical experience and observation.

Full textAbstract:
While the skills mismatch is well documented in EU labour market, it renders work-based learning a plausible part of the answer to this problem. Yet, a number of issues demand handling before work-based learning is effectively utilized. Systems inquiry, through systemic modelling, constitutes a proper framework to facilitate a holistic study of such complex social phenomena. From a systemic perception, the complexity of social systems has prevented a holistic study. The descriptive power of systemic modelling allows for such a study that relates labour-market to dual education via apprenticeship. Thus, the respective systems are studied as a whole; the challenges arising are specified and the limitations of the solution are clarified. The application of apprenticeship in heavily industrialized countries can yield results, but it may fail in countries like Greece with a very different socio-economic environment. Still, some recommendations can be formed for a variant of apprenticeship more attuned to such cases.

Full textAbstract:
This chapter discusses the machinery of digestion in giraffes. The shape of the mouth of giraffes, the shape and number of their teeth, the shape and size of their tongue and the arrangement of the muscles of eating are unique and have evolved to be perfectly suited to the task of browsing. Comminution of browse is eased by large volumes of saliva secreted from salivary glands that relative to body mass are small. The digestive tract of giraffes consists of a rumen, reticulum, and omasum in addition to the usual stomach and intestines found in any mammal. The forestomachs are smaller and the small and large intestines are longer than those of grazer-ruminants. The quality, succulence and consistency of browse reduces the need for prolonged rumination. Movement of browse through the rumen-reticulum is fast, and it is likely that a mixture of plant cell contents and saliva, can bypass the rumen via an esophageal groove, and be deposited directly into the stomach. 40% of daily energy (mainly in the form of volatile fatty acids) is provided by microbial fermentation of browse in the rumen, and 60% derives from intestinal digestion mainly of glucose), rather than the reverse as found in grazer-ruminants. Significant fermentation of undigested fiber (mainly hemicellulose) occurs in the large intestine. The combination of digestive processes results in very efficient use of the nutrients and an apparent digestibility of ~85%, which is high. To provide the browse needed to meet daily energy demand giraffes need a home range of ~60 km<sup>2</sup>.

This chapter provides an example of a secondary-education curriculum tailored to increase 21st century students´ motivation in second-language study by integrating digital learning into the classroom. The proposed syllabus is competency-based, open-structured, and promotes active learning within the constructivist paradigm. The research focus of this chapter suggests raising discussion on the practical benefits this type of curriculum design has on learning. The accompanying challenges that institutions face will also be addressed. The legal framework was based on public-school policy, the autonomous regulations in the Valencian Community, Spanish National Legislation, and the International Guidelines of the Council of Europe. The syllabus content is supported by such programs as Quizlet and Anki App for vocabulary acquisition; Kahoot, Socrative, and Jeopardy App for reading comprehension and grammar work; and Augment and HP Reveal for visuospatial stimulus via augmented reality. Web-based platforms such as Adobe Spark, Explain Everything, Nearpod, Padlet, and Canva, among others, were applied for digital story-making, videocast, interactive presentations, discussion boards, graphic-novel writing activities, etc. It should be noted that this design is just one of various options, that the current educational system in Spain is expecting curricular changes and that digital technology and internet-based resources need to be constantly checked for updates.

The accessibility of monuments and archaeological sites by disabled persons and persons with restricted mobility in general, constitutes a social, financial and political demand. The project “PROSPELASIS” attempted to counter this problem by focusing on creating a methodology for facing monuments' accessibility and perceptibility problems for people with disabilities and testing its application at Byzantine monuments of Thessaloniki. In six major monuments included in UNESCO's World Heritage List, significant accessibility improvements were realized. Α Wi-Fi information system was installed in all of them via which an audio and visual information system was created with audio information in three languages, description of visual information, text information, information in Greek and International Sign Language. Additionally, in Rotunda and Heptapyrgion monuments three dimensional models were developed. The successful validation of the proposed methodology constitute the results of this project not only pertinent to Thessaloniki or Greece, but worthy of a wider application.

Full textAbstract:
Ability to predict and control involved parameters and hence the outcome of sheet metal forming processes demand holistic knowledge of the product/-process parameter influences and their contribution in shaping the output product quality. Recent improvements in the ability to harvest inline production data and the capability to understand complex process behaviour through computer simulations opens up the possibility for new monitoring and control approaches for improving production process performance and output product quality. Current work presents a framework for monitoring and control of sheet metal forming processes which incorporates a hybrid dataand modelbased approach. An initial attempt to evaluate the proposed frameworks’ ability to support output product quality and process performance enhancements is made by implementing the proposed approach via an in-house built wire-bending machine prototype. Initial experiments conducted using the built prototype indicate that the proposed framework has the potential to support such enhancements and further work is needed to validate the overall framework.

Full textAbstract:
A qualitative analytical framework, policy discourse analysis, is applied to understand the prevalence of youth-targeting in national policies related to employment. Forty-seven policies from 13 Sub-Saharan African countries promulgated in 1996 to 2016 were selected for the evaluation, based on their direct or indirect relevance to youth employment via themes of development, rural transformation, and agriculture. The main findings show that policies focus more on promoting labour supply strategies, e.g. training programmes on entrepreneurship skills, rather than demand-side ones—such as reducing the constraints to business development and job creation at the sectoral level. Policies rarely touch on known constraints faced by youth, like their limited engagement in agribusiness activities and representation in policy dialogues. SSA policies with a youth employment lens associated to the different pillars of the Decent Work Agenda are assessed.

This introductory chapter provides an overview of Ken Russell's The Devils (1973). The 1970s proved to be a prolific period for Russell, but the decade closed with both the advent of home video and his slide in reputational and commercial terms, meaning reduced demand was in place for audiences to (re)discover Russell's earlier work via the new small-screen format. Russell's output in the 1980s was largely dismissed by audiences and critics alike, while the following decade saw the director turn out a series of boilerplate TV movies. Little was done in the way of seriously reappraising his body of work until the early 2000s, when his TV films on composers Delius and Elgar were released on DVD and work on a director's cut of The Devils began. While this did not immediately bring about that much interest in Russell's other films, it did prove to be the starting point for The Devils in regaining the recognition which had been absent for the best part of three decades. It is a film which provides plenty of material for analysis and discussion, and while this has always been the case, it is now especially timely given the exposure and acclaim the film has received in recent years.

Oil and gas exploration around the world continues at a rapid pace. This rapid pace of oil and gas exploration in North America has been fueled primarily thorough the development of horizontal drilling and the “fracking” process of underground shale formations. The demand for various grades and dimensions of API casing and pipe has and will continue to increase in the foreseeable future as these shale formations are exploited. To support this demand in North America, Gallatin Steel has embarked on a program to develop API casing and pipe coil skelp via their Compact Strip Plant (CSP). A key characteristic of API grade pipeline steels is excellent fracture toughness. This is one area where historically CSP facilities have struggled, especially in gauges greater than 8.8 mm (0.350″) due to overall lack of reduction from the thin slab design of a CSP facility. In addition, utilizing the typical Thermomechanical Control Processing (TMCP) separating recrystallized and non-recrystallized rolling used in API coil skelp production for strength and toughness of a traditional HSM or plate mill is difficult to achieve in the continuous CSP facility. Gallatin Steel has successfully developed, through a controlled combination of slab quality, alloy design, process modifications and process control, excellent toughness in both charpy and DWTT performance from a 65 mm (2.56″) slab in final coil thicknesses up to 12.7 mm (0.500″). This paper will describe the results achieved to date on various thicknesses from 7.6 mm to 12.7 mm API skelp development at Gallatin Steel. Mechanical property performance along with microstructures/grain size will be presented. In addition, future work that Gallatin Steel will undertake to further improve the capability to produce quality API coil skelp will be discussed.

Full textAbstract:
Abstract This paper describes a suggestion to improvise an integrated gas planning process through network optimization. As a prudent operator it is imperative to formulate long-term gas supply outlook and scenarios to ensure efficient and effective resource management with due considerations of growth strategies while maximizing value for purpose of production-focused conversations, technical assessment of forthcoming developments, commercial arrangement policy and strategic expansions. Also, it necessitates to develop and implement resolution plan arising from supply planning areas i.e. shortfall mitigation, facilities ullage, constraint and complying specifications commitment. It thereby imposes to implement robust network optimization workflow in place to improvise the integrated gas management cycle to manage the current existing gas supply and to also regulate strategy in terms of line-ups, evacuation path of forthcoming fields economically. Precedingly integrated gas planning exercise was executed via stacking up list of production sources with forecasted demands. The precedent approach was emphasized purely on mathematical and statistical method of capitalizing the production profile and geographical traits of the production sources. Notwithstanding, the approach usually linked with identified challenges and pain points throughout the planning cycle. Challenges and pain points in integrated gas planning were briefly outlined to understand limitations of existing work process as well as the need of improvising the same by embedding network optimization by simulation modeling. It was observed that multiple challenges did occur during planning preparation until post planning implementation. Workflow for strategic integrated gas planning was established to include step by step process to illustrate the ideal case otherwise known as base case scenario. The work process for constructing a mathematical model for integrated gas planning was demonstrated to reflect the complexity of the process and landscape network. For each process, expectations were clarified to ensure robustness of the analysis. The limitations in the mathematical/statistical model workflow process was complimented by the enhancing method through network optimization. Network optimization was evaluated by leveraging on the development of holistic integrated modelling for current complex offshore facilities to empower and safeguard the proposed line up of new fields meeting technical allowances such as ullage, pressure balancing & supply/demand requirements, contaminant management in accordance with strategic planning & operations. Novel idea was established to create physical prototype (network model) of offshore supply network with building components such as source (fields), connectors (export pipelines and highways), sinks (multiple terminals), and pressure boosters (pump/compressor) were embedded in model for landscape along with multiple receiving end terminals. Network simulation model was also validated with Plant information PI data to yield representative results prior deployment. Situational analysis (what-if scenarios) were conducted to evaluate to root cause analysis and troubleshooting at several nodes in the network to cater for harmonic balance. Gap analysis was also executed to identify the necessary alterations to operating philosophy, partial segregation of system to cater for product demand and quality. Simulation network model was also utilized to explore different evacuation routes that could adhere to business rules/standards to optimize the work process and boost up the efficiency of current network. The above approach of improvising the integrated gas planning through network optimization truly enhance the end to end value chain by constituting result matter in validating the mathematical planning model with technical simulation to ensure robustness in management decision of certain strategies for the planning scenarios. It could also advocate the planning numbers by ensuring the do-ability and steer optimal solution for value maximization by deciphering the impediments and strengthening the analysis.

Abstract Against the background of a growing deployment of renewable electricity production, like wind and solar, the demand for energy storage will only increase. One of the most promising ways to cover the medium to long-term storage is to use the excess electricity to produce hydrogen via electrolysis. In a modern energy grid, filled with intermittent power sources and ever-increasing problems to construct large power plants in densely populated areas, a network of Decentralised Energy Systems (DES) seems more logical. Therefore, the importance of research into the design of a small to medium-sized hydrogen fuelled micro Gas Turbine (mGT) unit for efficient, local heat and electricity production becomes apparent. To be able to compete with Reciprocating Internal Combustion Engines (RICEs), the mGT needs to reach 40% electrical efficiency. To do so, there are two main challenges; the design of an ultra-low NOX hydrogen combustor and a high Turbine Inlet Temperature (TIT) radial turbine. In this paper, we report on the progress of our work towards that goal. First, an improvement of the initial single-nozzle swirler (swozzle) combustor geometry was abandoned in favour of a full CFD (steady RANS) design and optimisation of a micromix type combustion chamber, due to its advantages towards NOx-emission reduction. Second, a full CFD design and optimisation of the compressor and turbine is performed. The improved micromix combustor geometry resulted in a NOx level reduction of more than 1 order of magnitude compared to our previous swozzle design (from 1400 ppm to 250 ppm). Moreover, several design parameters, such as the position and diameter of the hydrogen injection nozzle and the Air Guiding Panel (AGP) height, have been optimized to improve the flow patterns. Next to the combustion chamber, CFD simulations of the compressor and turbine matched the 1D performance calculations and reached the desired performance goals. A CFD analysis of the impact of the tip gap and exhaust diffuser cone angle led to a choice of these parameters that improved the compressor and turbine performance with a limited loss in efficiency.

Current clinical grafts used in tendon treatment are subject to several restrictions and there is a significant demand for alternative engineered tissue. The previously reported tendon scaffolds mainly based on electrospinning and textile technologies showed promising results for tendon regeneration. However, limitations, such as small pore size, nutrition transmission, cell attachment, exist universally in such scaffolds. In this work, a novel tissue engineered polycaprolactone (PCL) tendon scaffold based on electrohydrodynamic jet printing (E-Jetting) was developed for investigation. In preliminary in-vitro study, human tenocytes were seeded in scaffolds with pore size of ∼106 μm to investigate the cell attachment, morphology and alignment. This study suggested that E-jetted tendon scaffold highly mimicked hierarchical construction from fiber to fascicle level of the native tendon, and has potential to be an alternative tendon regeneration tool.

Full textAbstract:
The Markov technique for determining the Reliability Characteristics (Probability of Failure on Demand, availability, Mean time to repair and Mean time between failures) of the Safety Instrumented System (SIS) on Offshore Metering and Custody Transfer Facility in Campeche Bay Mexico is presented in this work. Two important factors were considered based on the ISA TR84.0.02, Part 4: a) Common Cause Failure and b) the diagnostics capabilities were taking into account. The Markov technique methodology employed in order to assess and determine the Reliability characteristics of SIS was compared with Fault Tree Analysis previously analyzed, Part 3 of ISA TR84.0.02; for which the hazard and risk analysis mandated a SIL 2 for the SIS with two sets of sensors where each individual sensor can shut down the operation of the facility. Aspects like voting, redundancy or diversity bring about a full Markov model of a SIS, but it usually consists of intermediates states not significant for the assessment of the reliability characteristics. The quantitative results will mostly depend on the direct transitions to the fail-safe and fail-dangerous states. As a result, in most cases it was not necessary to present a fully developed model.

Abstract The majority of wave energy devices operate close to resonant conditions to enhance energy conversion resulting in large displacements. As a result, nonlinearities significantly contribute to the dynamics of the system. A typical approach to predict the behavior of the system and power output relies on the derivation of a mathematical model in the time domain to simulate the dynamics through some numerical codes. However, a relatively high computational demand is required for those simulations. In this regard, the present work deals with the nonlinearities in the frequency domain via Statistical Linearization. Two different power-take-off systems are investigated, a linear and a hydraulic one, and their mean power calculations are derived based on the Statistical Linearization. The reliability of the method is verified against the Power Spectrum Density (PSD) of nonlinear time domain simulations. Only the heave motion is analyzed, and several nonlinearities commonly reported for Point Absorbers (PA) were considered, such as cubic stiffness, geometric nonlinearities, drag forces, and Coulomb forces. The approach employed in this work offers a reliable estimation of body dynamics for all nonlinearities considered. In addition, the present method produced a fast estimation, which can be valuable for the assessment of several designs and sea load conditions.

Full textAbstract:
Observations of design review sequences by means of Virtual Reality (VR) and participant interviews have demonstrated that improvements may be made through providing selected user functions to participants who would otherwise just be observers. These functions are found from a survey of more or less experienced VR users in design reviews. The basic idea is that the participants are given access to special review data via App and smart device and are thus capable of immediately controlling the view of the product under review. Thus, for instance, the participants are able to download the structure tree including the components of the product to be tested onto their devices, navigate inside the structure tree, and get information about component parameters independently of the other participants. Participants can also configure the representation of the VR model displayed for all participants via smart device (highlighting, visibility, colour, ...) and set up the view. This makes communication easier, since otherwise the respective settings have to be administered by a VR operator. Special user interaction functions may improve the control of design reviews by changing the participants’ role from passive to active. A special requirement is the spatial selection of model components in the stereoscopic VR view. To meet this demand a Leap Motion controller transmits position data from the users hand to the pointer of the VR System via the protocol Virtual Reality Peripheral Network (VRPN).

"SELECTIVE FORMATION OF LINEAR ALPHA-OLEFINS VIA MICROWAVE CATALYTIC CRACKING OF LIQUID STRAIGHT-CHAIN ALKANES." In Ampere 2019. Universitat Politècnica de València, 2019. http://dx.doi.org/10.4995/ampere2019.2019.9894.
Full textAbstract:
Linear even-carbon-number alpha-olefins (LAO) with four or more carbon atoms are important compounds of high demand in chemical industry as precursors of a wide range of value-added chemicals [1]. LAO are used as co-monomers for polyethylene production, for the production of alcohols (mainly in detergents and plasticizers) and for synthesis of polyalphaolefins (used in synthetic lubricants). Alpha-olefins (C4, C6, C8 and C10) are mainly used to produce poly(vinyl chloride) plasticizers, high-density and linear low-density polyethylene to impart the stress-crack resistance. C10–C14 alpha-olefins can be used to synthesize linear alkylbenzene sulfonates (synthetic detergents). A conventional route to produce alpha-olefins is oligomerization of ethylene. The process provides production of high quality alpha-olefins but is very costly. If not oligomerization, LAO can be produced by thermal cracking of waxy paraffins but the product is not pure and contains numerous internal olefins, dienes and paraffin impurities. The process is conducted in the vapor phase at relatively low cracking temperatures and needs rapid quenching to prevent side reactions such as isomerization or cyclization. In our previous work [2], we showed that the selectivity to alpha-olefins can be increased considerably via catalytic cracking of n-alkanes under selective MW heating of catalysts. In the present work, the general regularities of MW cracking of n-alkanes are presented. Porous ceramic matrix Al2O3/Al composites (ceramometals) and various carbon materials (CM) having high dielectric losses were studied as supports of the catalysts. MW cracking was conducted with n-C16H34 and n-C28H58. The influence particle size and surface morphology of ceramometals and CM on the structural and group composition of the products was studied. It was established that LAO (C2-C23) and n-alkanes (C2-C26) were the main cracking products under selective MW heating of the used supports. The quantitative analysis of the products demonstrated that the liquid-phase process is more selective to alpha-olefins at the MW catalytic cracking than at the convectional thermal cracking. Silica modification of the surface of CM was shown to suppress spark discharge (usually observed at MW heating of CM); hence, the thermal cleavage of C-C bonds on the CM surface but not in the plasma discharge contributes the most to the formation of radicals. It was shown that the selectivity to liquid alpha-olefin could be more than 85 % under MW heating of cermets in region of the E - field node and decrease considerably in the region of H - field node.

Full textAbstract:
Google partnered with Via to launch an on-demand microtransit called Via2G between January and March 2020. The pilot provided employees with free travel to/from two of its offices in suburban, congested Silicon Valley. While the pilot was cut short due to COVID-19, rider participation grew steadily during operation. Of trip requests, 8,636 (87.8%) resulted in a ride offer. Unfulfilled requests were primarily outside of pilot operating times or when rider demand exceeded driver supply. Most users (72%) completed at least two trips, although recurring users were less likely to complete errands on the commute and fewer had a car available for commuting compared to all surveyed Google employees. Prior to Via2G, two-thirds (66%) of survey respondents drove to work at least one day per week, while a plurality (42%) drove five days per week. Compared to non-participants, pilot users were more likely to take ride-hail (14 vs 22 percent) or the Google Bus (24 vs 30 percent) at least once a week prior to the pilot. Recommendations suggest iterations for Google or other centralized employers to consider in future microtransit programs.
