Background Poor maternal diets increase the risk of excess gestational weight gain which can contribute to serious intergenerational morbidity for both the mother and infant. Pregnant young women with low incomes have disproportionately high rates of inadequate fruit and vegetable consumption as well as excess weight gains during pregnancy. Objective Our aim was to describe the feasibility and acceptability of Special Delivery, a longitudinal nutrition intervention that delivers healthy foods to pregnant youth (aged 14-24 years) with low incomes. Methods The Special Delivery pilot study, conducted in Michigan, enrolled pregnant young women with low incomes. Study participants were sent twice-monthly grocery deliveries consisting of US $35 worth of healthy foods, primarily fruits and vegetables. Between grocery deliveries, participants received daily SMS text message prompts to confirm receipt of delivery and document diet and weight. Program feasibility was assessed by the number of grocery orders placed, delivered, and confirmed by participants. Qualitative interviews and SMS text message data were used to determine acceptability by assessing participants’ perspectives on grocery delivery, participants’ perspectives on dietary impact of the program, and foods consumed by participants. Results A total of 27 participants were enrolled in the pilot study. The mean age was 20.3 years (SD 2.0), and 59.3% (16/27) were African American or Black. During the pilot, 263 deliveries were sent with 98.5% (259/263) successful deliveries and 89.4% (235/263) deliveries confirmed by participants. Participants reported that grocery delivery was convenient; that delivered foods were high quality; and that the program improved their diet, increased access to healthy foods, and promoted healthy habits during pregnancy. Conclusions A grocery delivery–based weight gain and nutrition intervention is both feasible and acceptable among low-income pregnant youth. Grocery deliveries were successfully completed and participants were willing and able to receive grocery deliveries, eat the healthy foods that were delivered, and communicate via SMS text message with study coordinators. The Special Delivery program warrants further evaluation for efficacy in promoting healthy weight gain for low-income youth during pregnancy.

Abstract Disassortative mating in color-polymorphic raptors is a proposed mechanism for the maintenance of color polymorphism in populations. Selection for such a mating system may occur if there are fitness advantages of mating with a contrasting morph. In the black sparrowhawk (Accipiter melanoleucus), mixed-morph pairs may have a selective advantage because they produce offspring that have higher survival rates. Two hypotheses, which may explain the mechanism, are the “avoidance-image” and “complementarity” hypotheses. The first suggests that, within a predator’s territory, prey develop a search image for the more commonly encountered parental morph, for example, the male morph during incubation and brooding. Females of a contrasting morph to their partner would then have higher capture rates once they commence hunting in the later nestling phase. Thus, the “avoidance-image” hypothesis predicts higher provisioning rates for mixed-morph pairs. Alternatively, the “complementarity” hypothesis posits that different color morphs exploit different environmental conditions, allowing mixed-morph pairs to hunt under a wider range of conditions and predicts that food is delivered more consistently. We test these hypotheses using nest cameras to record prey delivery rates during the late nestling phase when both parents are hunting. We found support for the “complementarity” hypothesis, with mixed-morph pairs delivering food more consistently but not at a higher rate. This higher consistency in prey deliveries may explain the improved survival of the offspring of mixed-morph pairs and could, therefore, play a role in maintaining the stability of color polymorphism in this system.

In this paper, a new variant of the Heterogeneous Dial-a-Ride Problem (HDARP) is innovatively applied to a routing problem of trucks picking up and delivering full and empty containers in the logistic chain, including container depots, importers demanding full containers and exporters requesting empty containers. On the route different types of trucks pick-up and deliver full and empty 20- and 40-foot containers. We consider trucks that are operated by alternative fuel, as well as the need for refuelling of trucks in any alternative fuel station to eliminate the risk of running out of fuel during its route. The objective of the paper is to contribute to the optimization of container truck transport routing with multiple pick¬ups and deliveries by providing a mathematical programming model aiming at minimizing the transportation cost as well as the negative environmental impacts.

Through a literary review of recent research, this paper examines the mixed impact of health information technology (HIT) on patient care, medical errors, and the quality of healthcare delivery in selected hospital settings such as emergency departments. Specific technologies examined include the electronic health record (EHR), medical devices, artificial intelligence, and robotics. The paper identifies that some healthcare technologies are increasingly valuable in reducing medical errors, improving healthcare quality, and in producing better patient-centered outcomes. It also determines that technologies have complicated the delivery of quality patient care, increased the incidences of clinician burnout, and made receiving quality healthcare in America's hospital systems possibly less sure. The paper concludes with some suggestions for improving HIT's implementations and confirms the need for further evaluation of the impact of HIT in increasing patient safety and clinician well-being.

Introduction Limited data exist on the outcome of pregnancies and deliveries in women with ischaemic stroke. We investigated the incidence of pregnancy- and delivery-related complications in women with ischaemic stroke before and after pregnancy compared with stroke-free matched controls. Patients and methods Of our 1008 consecutive patients aged 15–49 years with first-ever ischaemic stroke, 1994–2007, we included women with pregnancy data before or after stroke recorded in the Medical Birth Register (MBR) ( n = 152), and for them searched stroke-free controls matched by age, parity, year of birth, residential area and multiplicity ( n = 608). Data on hospital admissions and deaths (1987–2014) came from national health registries. Poisson regression mixed models allowed comparison of the incidence of complications. Results A total of 124 stroke mothers had 207 singleton pregnancies before and 45 mothers 68 pregnancies after stroke. The incidence rate ratio (IRR) for the composite outcome of pregnancy and delivery complications adjusted for socioeconomic status and maternal smoking was 1.43 (95% confidence interval [CI] 1.00–2.03, p = 0.05) for pre-stroke mothers, and 1.09 (95% CI 0.66–1.78) for post-stroke mothers, compared with matched controls. Similarly, the adjusted IRR for post-stroke hospital admission during pregnancy was 1.85 (95% CI 1.03–3.31). The IRR for perinatal death of the child was 3.43 (95% CI 0.57–20.53) before and 8.88 (95% CI 0.81–97.95) after stroke. Discussion and conclusions Compared with stroke-free mothers, we found a higher incidence of pregnancy- and delivery-related complications in mothers with ischaemic stroke. Larger studies are needed to verify our results.

Many companies do not prioritize warehouse logistics sufficiently in their core business, with the help of increased knowledge, more companies can reduce non-value-creating activities on their warehouse space. There is research and methods designed for standard warehouses that help reduce picking time and non-value-adding activities, however, there is not enough research regarding companies with limited warehouse space and how they can work towards continuous improvement. The purpose and contribution of the study is increasing knowledge of how companies with limited warehouse space can manage and time-efficient their warehouse space with the help of warehouse logistics. A qualitative case study has been performed with observations and an interview where picking time has been the main focus. The collection of the theoretical framework has been reviewed and revised through scientific articles and other literature to strengthen the empirical research. The research is delimited and focuses on limited storage areas. More specifically, the study has placed its emphasis on warehouse logistics and picking time. The study looked at a company's limited storage space and focused on a small part in a delivery, from arrival control to storage. In the empirical study, a case company has been studied and confirmed that warehouse logistics needs to be given better priority in companies with limited warehouse space. With the help of reduced time in warehouse routines, many companies can reduce non-value-creating activities. The purpose of the study and issues will contribute to future research and can be used as a basis. Future research will also help other companies in the same situation to eliminate non-value-adding activities and reduce picking time.
Många företag prioriterar inte lagerlogistik tillräckligt i sin kärnverksamhet, med hjälp av en ökad lagerlogistik-kunskap kan fler företag reducera icke-värdeskapande aktiviteter på lagerytan. Det exister forskning och metoder som är utformade för standardlager som hjälper till att reducera plocktid och icke-värdeskapande aktiviteter, däremot saknas det tillräcklig forskning gällande företag med begränsad lageryta och hur dom kan arbeta mot ständiga förbättringar när det kommer till lagerlogistik.  Studiens syfte och bidrag ligger i att öka kunskapen om hur företag med begränsad lageryta, med hjälp av lagerlogistik, kan hantera och tidseffektivisera sin lageryta. En kvalitativ fallstudie har utförts med observationer och mejlkommunikation där plocktid varit huvudfokus. Samling av det teoretiska ramverket har genom vetenskapliga artiklar och annan litteratur granskats och reviderats för att stärka den empiriska undersökningen. Forskningen avgränsas och fokuserar på begränsade lagerytor. Mer specifikt har studien lagt sin vikt på lagerlogistik och plocktid. Studien har tittat på ett fallföretags begränsade lageryta och på en liten del i en leverans, från ankomstkontroll till förvaringsförråd.  I den empiriska undersökningen har ett fallföretag studerats och bekräftat att lagerlogistik behöver prioriteras bättre hos företag med begränsad lageryta. Med hjälp av reducerad tid vid lagerrutiner kan många företag reducera icke-värdeskapande aktiviteter. Studiens syfte och frågeställningar kommer att bidra till framtida forskningar och kan användas som underlag. Framtida forskning kommer även bidra med att hjälpa andra företag i samma sits att eliminera icke-värdeskapande aktiviteter och reducera plocktid.

Le problème d’approvisionnement conjoint (JDP) proposé est un problème de planification des tournées de livraisons sur un horizon de temps décomposé en périodes élémentaires, l’horizon de temps étant la période commune de livraison de tous les produits,. La donnée de ces paramètres permet d’obtenir une formulation linéaire du problème, avec des variables de décision binaires. Le modèle intègre aussi des contraintes de satisfaction de la demande à partir des stocks et des quantités livrées, des contraintes sur les capacités de stockage et de transport.Afin de résoudre aussi le problème de choix des tournées de livraison, il est nécessaire d'introduire dans le modèle des contraintes et des variables liées aux sites visités au cours de chaque tour. Il est proposé de résoudre le problème en deux étapes. La première étape est le calcul hors ligne du coût minimal de la tournée associé à chaque sous-ensemble de sites. On peut observer que pour tout sous-ensemble donné de sites, le cycle hamiltonien optimal reliant ces sites à l'entrepôt peut être calculé à l'avance par un algorithme du problème du voyageur de commerce (TSP). Le but ici n'est pas d'analyser pleinement le TSP, mais plutôt d'intégrer sa solution dans la formulation de JRP. .Dans la deuxième étape, des variables binaires sont associées à chaque tour et à chaque période pour déterminer le sous-ensemble de sites choisi à chaque période et son coût fixe associé
The proposed joint delivery problem (JDP) is a delivery tour planning problem on a time horizon decomposed into elementary periods or rounds, the time horizon being the common delivery period for all products. The data of these parameters provides a linear formulation of the problem, with binary decision variables. The model also incorporates the constraints of meeting demand from stock and the quantities supplied, storage and transport capacity constraints.In order to also solve the problem of choice of delivery rounds, it is necessary to introduce in the model several constraints and variables related to the sites visited during each round. It is proposed to solve the problem in two steps. The first step is the calculation of the minimum off-line cost of the tour associated with each subset of sites. One can observe that for any given subset of sites, the optimal Hamiltonian cycle linking those sites to the warehouse can be calculated in advance by a traveling salesman problem algorithm (TSP). The goal here is not to fully analyze the TSP, but rather to integrate its solution in the formulation of the JRP. In the second stage, binary variables are associated with each subset and each period to determine the selected subset of sites in each period and its associated fixed cost

Student voice could improve the effectiveness of sex education curricula, student input, however, is generally limited or totally absent in sex education development. This dissertation explores student content preferences in sex education curricula and how school officials can incorporate student feedback to ensure content is relevant, relatable, and reliable. Results also show that adolescents are in favor of receiving social media-delivered sex education from local health departments. To build an adolescent following and greater awareness about SNS accounts that disseminate sex education, participants suggested LHDs 1) inform intended audiences about products by building offline connections 2) use promotions to create awareness 3) emphasize price during giveaways, publicize free services and 4) use the right people to motivate others to follow accounts.

This book provides a comprehensive and up-to-date introduction to Hodge theory—one of the central and most vibrant areas of contemporary mathematics—from leading specialists on the subject. The topics range from the basic topology of algebraic varieties to the study of variations of mixed Hodge structure and the Hodge theory of maps. Of particular interest is the study of algebraic cycles, including the Hodge and Bloch–Beilinson Conjectures. Based on lectures delivered at the 2010 Summer School on Hodge Theory at the ICTP in Trieste, Italy, the book is intended for a broad group of students and researchers. The exposition is as accessible as possible and does not require a deep background. At the same time, the book presents some topics at the forefront of current research. The book is divided between introductory and advanced lectures. The introductory lectures address Kähler manifolds, variations of Hodge structure, mixed Hodge structures, the Hodge theory of maps, period domains and period mappings, algebraic cycles (up to and including the Bloch–Beilinson conjecture) and Chow groups, sheaf cohomology, and a new treatment of Grothendieck's algebraic de Rham theorem. The advanced lectures address a Hodge-theoretic perspective on Shimura varieties, the spread philosophy in the study of algebraic cycles, absolute Hodge classes (including a new, self-contained proof of Deligne's theorem on absolute Hodge cycles), and variation of mixed Hodge structures.

This book presents an important breakthrough in arithmetic geometry. In 2014, this book's author delivered a series of lectures at the University of California, Berkeley, on new ideas in the theory of p-adic geometry. Building on his discovery of perfectoid spaces, the author introduced the concept of “diamonds,” which are to perfectoid spaces what algebraic spaces are to schemes. The introduction of diamonds, along with the development of a mixed-characteristic shtuka, set the stage for a critical advance in the discipline. This book shows that the moduli space of mixed-characteristic shtukas is a diamond, raising the possibility of using the cohomology of such spaces to attack the Langlands conjectures for a reductive group over a p-adic field. The book follows the informal style of the original Berkeley lectures, with one chapter per lecture. It explores p-adic and perfectoid spaces before laying out the newer theory of shtukas and their moduli spaces. Points of contact with other threads of the subject, including p-divisible groups, p-adic Hodge theory, and Rapoport-Zink spaces, are thoroughly explained.

Integration is where one method influences in some way the objectives, sampling, data collection, analysis, or interpretation of the other methods within a mixed methods study. Studies of qualitative research undertaken with RCTs have identified that publications often have no evidence of integration of findings. That is, the promise of qualitative research helping to explain the RCT results is simply not delivered in practice, or at least not in a way that is visible outside the original research team. The focus of this chapter is on where integration can occur within a study, the techniques that can facilitate integration, and examples of integration in the context of qualitative research and RCTs.

Physiological monitoring using a variety of technological advances supplements, but does not replace, our ability to distinguish normal from abnormal physiology traditionally gleaned from physical examination. Pulse oximetry uses the wavelengths of saturated and unsaturated hemoglobin to estimate arterial oxygenation noninvasively. Similar technology included on vascular catheters provides estimation of central or mixed venous oxygenation and helps assess the adequacy of oxygen delivered to tissues. End-tidal carbon dioxide measurements contribute to the assessment of ventilation. Systemic arterial blood pressure and central venous pressure measurements help evaluate cardiac performance, including the impact of ventilatory support. Intra-abdominal pressure may increase as a result of intraluminal air or fluid, abnormal fluid collections within the peritoneal cavity, or abnormal masses. Increased pressure may impede venous return to the heart and compromise intra-abdominal organ perfusion. Pressure measurement guides related management decisions.

American self-help authors, coaches, and sexologists selectively adopt and apply Buddhist meditation techniques to meet their goals and sell products. This chapter draws upon books, articles, podcasts, TED talks, and other sources to demonstrate how these new applications of mindfulness are touted to enhance the sex act, delivering greater pleasure or effectively managing dysfunction. Key concepts include analysis of the economics involved in the appropriation of Buddhist practices, the role of gender in the “secular” use of meditation (almost all books recommend mindful sex for women, but few focus on men), the mixed Asian and Western frameworks for understanding the body and the meaning of sex, and the alternate uses to which elements of Buddhism may be put in different cultural settings. A specific genre of the use of meditation serves as a means to explore secular developments that draw upon Buddhist sources in a sometimes uneasy relationship.

Welfare community projects, mainly related to health care, are essential for the development of societies. For this reason, the optimization of its resources through methodologies that support decision making becomes of interest for all stakeholders in order to reach the target users. In Colombia, particularly in the city of Medellin, several social projects are being developed seeking to provide health and other social services to vulnerable populations. The purpose of this chapter is to deal with a real application of the home health care routing and scheduling problem (HHCRSP), in which a set of health professionals grouped by teams should visit a set of users geographically scatter over the city. Here, it is proposed a mixed integer linear model and a heuristic solution approach. The mathematical model is based on vehicle routing problem with pickups and deliveries (VRPPD) with additional features related with the specific application and geographical conditions.

The depletion of natural resource, the complexity of economic markets and the increased requirement for environment protection have increased the uncertainty of chemical supply and manufacturing. The consequence of short-time material shortage or emergent demand under extreme conditions, may cause local areas to suffer from delayed product deliveries and manufacturing disorder, which will both cause tremendous economic losses. In such urgent events, robust optimization for manufacturing planning and supply chain design in chemical industry, targeting the smart manufacturing, should be a top priority. In this chapter, a novel methodology is developed for robust optimization of manufacturing planning and supply chain design in chemical industry, which includes four stages of work. First, the network of the chemical supply chain needs to be characterized, where the capacity, quantity, and availability of various chemical sources is determined. Second, the initial situation under steady conditions needs to be identified. Then, the optimization is conducted based on a developed MILP (mixed-integer linear programming) model in the third stage. Finally, the sensitivity of the manufacturing and transportation planning with respect to uncertainty parameters is characterized by partitioning the entire space of uncertainty parameters into multiple subspaces. The efficacy of the developed methodology is demonstrated via a case study with in-depth discussions.

Technological innovations are changing the way education is delivered. With instructional media evolving at an exponential pace, instructional designers and educators have a variety of options when deciding what tools are best for delivering their instruction. Simulation and virtual environments are a growth area in aviation, defense, crisis management, medicine, and customer service, but the utilization of this technology in the field of educational leadership or in principal preparation programs is very much in an embryonic stage. In this chapter, the authors first provide a summary of the evolution of scenario simulation in the field of educational leadership, and develop ‘learning principles' for evaluating the effectiveness of the simulation in delivering discrete learning outcomes. They then provide a specific example of an innovative educational leadership program that is utilizing a specific virtual environment; introduce TLE TeachLivE™ (TeachLivE) as a method to help prepare future leaders for practice. Finally, they discuss professional avenues to consider while cultivating the advancement of TeachLivE™ as a supplemental method for learning.

Chapter 5 continues the story begun in chapter 4, when a split between Chicano Democrats and Chicano/Mexicano immigrant rights activists leads to the exodus of the latter from the statewide MAPA organization to the seemingly more radical politics of La Raza Unida Party, an ethnic third party effort. The chapter explores how this moment led to debates between various factions of the California La Raza Unida Party through which San Diego Chicano/Mexicano activists participated from roughly 1970-1975. Community activists in San Diego LRUP facilitated an approach in between a persistent narrow nationalism that, despite rhetoric otherwise, deemphasized the noncitizen migrant experience and struggled to embrace the diverse political positions within the ethnic Mexican community. San Diego Chicano/Mexicano LRUP organizers maintained engagement with the diverse ethnic Mexican community in their registration efforts, as they continued to learn about the limits of voting strategies in their mixed-legal status community.

This task assesses the following clinical skills: … ● Patient safety ● Communication with patients and their relatives ● Information gathering ● Applied clinical knowledge … You are a ST5 doctor in the urogynaecology clinic. You are asked to see Amanda Scott, who is a 64- year- old woman. She has been referred by her GP with mixed urinary incontinence which has not responded to supervized pelvic floor muscle training, bladder retraining and Tolterodine. She is para 2 with two spontaneous vaginal deliveries. She has no significant medical or surgical history. Previous examination did not reveal any pelvic organ prolapse. A urodynamic study was performed before her clinic appointment (see Fig 19.1). Amanda wishes to know more about the urodynamic findings and management options available to her. You will have ten minutes for the initial discussion. Once you have finished discussion with Amanda the assessor will ask you some questions. You have 10 minutes for this task (+ 2mins initial reading time). Please read instruction to candidate and actor. There are some marks on the process mark sheet for the actor to assign at the end of the station. Record your overall clinical impression of the candidate for each domain (i.e. should this performance be pass, borderline, or a fail). You are Amanda Scott, a 64- year- old mother of two. You have been experiencing a sudden, desperate need to pass urine and urine leakage if you don’t get to the toilet on time for the last three years. You also have episodes of unwanted loss of urine on coughing, laughing, physical exercise, and sexual intercourse. Your bowel function is normal and you are not aware of any vaginal ‘bulge’. You went through the ‘change’ (menopause) at the age of 52. You had two uneventful normal (vaginal) births. You are healthy without any previous operations. You have seen a physiotherapist for pelvic floor exercises and you have tried a drug for your bladder called Tolterodine (one 2mg tablet twice a day). Unfortunately, you haven’t seen any improvement of your symptoms.

As a result of the COVID-19 pandemic, faculty at a Hispanic serving institution shifted from face-to-face to totally online teaching. The authors describe two assignments for teacher candidates that required them to design and deliver lessons that focused on practicing two high-leverage practices utilizing Mursion, a mixed-reality simulation (MRS) software and platform. MRS sessions were delivered through Zoom video conferencing and were delivered asynchronously. Benefits, challenges, and limitations of using MRS in conjunction with Zoom in online courses were identified and discussed. Detailed logistics for planning, preparing, and executing MRS effectively were provided. The authors describe implications for remote learning as it related to teaching at an HSI located in one of the poorest areas of the U.S., with one of the most vulnerable populations.

Mobile learning has the potential to increase the opportunities to make teaching and learning available beyond the traditional classroom. The main aim of this study was to develop a mobile technologies course delivered online and explore the effects of this online course designed on mobile technologies on the use of ICT skills, attitudes, and views of EFL instructors. While employing mixed methodology, explanatory sequential research design was applied. In this study, participants were selected through convenient sampling and the data were collated through a questionnaire used as pre- and post-tests, followed by semi-structured interviews and class observations. The results of this study indicated that the online training course on mobile technologies had a positive impact on the use of ICT skills and EFL teachers' views in general. Further, attending the mobile technologies course delivered online was very beneficial and effective for the instructors in that it helped them to develop their skills on the use of mobile technologies in English language teaching.

A mixed-mode or ‘‘flipped’’ model of learning focusses on supporting a high level of student engagement, student motivation, and the transferability of specific course content. A blend of online resources and face-to-face (F2F) learning facilitates meaningful interaction between peers, while building a capacity for self-directed and lifelong learning. Within the School of Medical Science, Anatomy and Physiology (A&P) content was ‘flipped’ for delivery at a new campus to align with the traditional F2F offering. Lectures were delivered online, while tutorials and practicums were F2F.. Collaborative learning opportunities utilizing active learning pedagogies was appealing and was integrated during the re-alignment of A&P which was delivered to a cohort of allied health students undertaking their first year of their program. This study assessed how this type of learning was received by students (from the same program) undertaking the same course in an on-campus F2F delivery. Students completed surveys relating to their experiences in learning activities applied in: lectures, tutorials and practicums. In addition, academic outcomes (theoretical and practical) across the two modalities were also evaluated. Overall, students undertaking the mixed-mode delivery performed significantly better in theoretical assessments, while performance in practical assessments was comparable between both deliveries. Student preferences to learning and teaching activities was mixed, however all students highly valued the use of “mini-quizzes” in lectures, tutorials and practicums.

The ligase detection reaction (LDR) is a technique that can distinguish low-abundant mutant DNAs from wild-type DNAs. LDR is usually carried out on DNAs amplified using the polymerase chain reaction (PCR). In the realization of modular microfluidic systems, the DNA output of the PCR handed off to the LDR chip needs to be mixed with LDR reagents before continuing the reaction. Polymer, continuous flow ligase detection reaction (CFLDR) devices with integrated passive micromixers, were designed, fabricated and tested. The devices each consisted of: a passive mixer for mixing a PCR sample, a cocktail of primers, and ligase, an enzyme of DNA; an incubator channel (95°C) for preheating the mixture; and a thermal cycling channel for the LDR. The devices were produced by hot embossing polycarbonate (PC) substrates with brass mold inserts manufactured by micro-milling. Experiments using food dyes showed that the appropriate mixture concentrations were delivered to the preheating channel in both the pulling and pushing modes.

State-of-the-art turbomachinery design processes rely more and more on the extensive use of numerical simulations. To deal with expensive high-fidelity computations, surrogate-based optimisation (SBO) has become a very interesting approach. In order to cope with industrial cases, the capability to handle variables of a mixed nature appears key. Innovative and auto-adaptive surrogates have been implemented within Minamo that are capable of natively handling the different natures of the design parameters. The present work discusses this mixed-variable SBO framework applied to a multi-profile combinational problem inside the bypass duct. A proof of concept is given followed by a more advanced application. It is demonstrated that the proposed mixed-variable SBO efficiently delivers reliable results and that it offers many opportunities during a conceptual design phase.

Fluid flow with particles are found in many engineering applications such as flows inside lab-on-a-chips and heat exchangers. In heat exchangers, nanofluids or base fluids mixed with nanoparticles are applied to be used as the working fluid instead of the traditional base fluids which have low thermal-physical properties. The nanoparticle diameters are in the range from 1 to 100 nanometers are mixed with the traditional base fluids before they are applied inside the heat exchangers and the nanofluids have been proved continually that they enhance heat transfer rates of the heat exchangers. Turbulent and laminar nanofluid flows have shown different enhancements in different conditions. This work focused on comparing different turbulent nanofluid simulations which used the computational fluid dynamics, CFD, with different multiphase models. The Realizable k-ε turbulence model coupled with three multiphase models; Volume of Fluid (VOF) model, Mixture model and Eulerian model, were considered and compared. The heat exchanger geometry in the work was rectangular as in the electrical device application and the nanofluid was a mixture between Al2O3 and water. All simulated results, then, were compared with experimental results. The comparisons showed that numerical results did not deviate from each other but their delivered-time consumptions and complications were different. If one develops his own code, Eulerian model was the most complicated while Mixture model and Eulerian model consumed longer performing times. Although the Eulerian model delivered-time consumption was long but it provided the best results, so the Eulerian model should be chosen when time consumption and errors play important roles. From this ordinary study, the first significant step of in-house program developments has started. The time consumption still indicated that the high performance computers should be selected, and properties obtained from the experimental studies should be imported to the simulation to increase the result accuracy.

This paper describes experimental and numerical investigations of the flow fields delivered to the inlet of a radial turbine rotor by vaned and vaneless stators, and to what extent they influence the stage performance. The work focussed on the flow fields delivered to the inlet of an 86mm turbine by 3 pairs of vaned and vaneless housings, each pair having matching flow capacities. Static pressure measurements at rotor inlet were acquired, and from these the circumferential flow distributions at rotor inlet were directly compared. The experimental results were used to validate numerical models to study the rotor inlet flow fields in greater detail. Both numerical and experimental results highlighted the vaneless stators to deliver a higher level of uniformity at rotor inlet. The comparatively higher levels of non-uniformity in the vaned stator builds can be primarily attributed to jet and wake effects, as these were found not to have mixed out significantly at the rotor inlet and contributed both to the overall levels of pressure loss and higher variations of rotor inlet incidence. Comparisons have been made to previously reported turbine performance data, and the influence of the rotor inlet flow field on stage running performance has been discussed.

The world’s richest renewable energy resources — of large geographic extent and high intensity — are stranded: far from end-users with inadequate or nonexistent gathering and transmission systems to deliver the energy. The energy output of most renewables varies greatly, at time scales of seconds to seasons: the energy capture assets thus operate at inherently low capacity factor (CF); energy delivery to end-users is not “firm”. New electric transmission systems, or fractions thereof, dedicated to renewables, will suffer the same low CF, and represent substantial stranded capital assets, which increases the cost of delivered renewable-source energy. Electric energy storage cannot affordably firm large renewables at annual scale. At gigawatt (GW = 1,000 MW) scale, renewable-source electricity from diverse sources, worldwide, can be converted to hydrogen and oxygen, via high-pressure-output electrolyzers, with the hydrogen pipelined to load centers (cities, refineries, chemical plants) for use as vehicle fuel, combined-heat-and-power generation on the retail side of the customers’ meters, ammonia production, and petroleum refinery feedstock. The oxygen byproduct may be sold to adjacent dry biomass and / or coal gasification plants. Figures 1–3. New, large, solution-mined salt caverns in the southern Great Plains, and probably elsewhere in the world, may economically store enough energy as compressed gaseous hydrogen (GH2) to “firm” renewables at annual scale, adding great market and strategic value to diverse, stranded, rich, renewable resources. Figures 2 and 3. For example, Great Plains, USA, wind energy, if fully harvested and “firmed” and transmitted to markets, could supply the entire energy consumption of USA. If gathered, transmitted, and delivered as hydrogen, about 15,000 new solution-mined salt caverns, of ∼8 million cubic feet (225,000 cubic meters) each, would be required, at an incremental capital cost to the generation-transmission system of ∼5%. We report the results of several studies of the technical and economic feasibility of large-scale renewables — hydrogen systems. Windplants are the lowest-cost new renewable energy sources; we focus on wind, although concentrating solar power (CSP) is probably synergistic and will become attractive in cost. The largest and richest renewable resources in North America, with high average annual windspeed and sunlight, are stranded in the Great Plains: extant electric transmission capacity is insignificant relative to the resource potential. Large, new, electric transmission systems will be costly, difficult to site and permit, and may be difficult to finance, because of public opposition, uncertainties about transmission cost recovery, and inherently low CF in renewables service. The industrial gas companies’ decades of success and safety in operating thousands of km of GH2 pipelines worldwide is encouraging, but these are relatively short, small-diameter pipelines, and operating at low and constant pressure: not subject to the technical demands of renewables-hydrogen service (RHS), nor to the economic challenge of delivering low-volumetric-energy-density GH2 over hundreds or thousands of km to compete with other hydrogen sources at the destination. The salt cavern storage industry is also mature; several GH2 storage caverns have been in service for over twenty years; construction and operating and maintenance (O&M) costs are well understood; O&M costs are low.
