Abstract:
The two ventricles of the fetal sheep heart have anatomic and biochemical differences that account for their differing functional capabilities and blood flows. Coronary flows to both ventricles have been measured using radiolabeled microspheres [or left ventricular (LV) flow, by Doppler sensor on the circumflex coronary artery] during experiments of pressure loading and chronic and acute hypoxemia. Blood flow to the left ventricle with its lower wall tension is about two-thirds the flow per gram compared with the right ventricle (RV). Acute systolic pressure loading of the RV to its maximal work capability stimulates flow to double (from ∼250 to 500 ml ⋅ min−1 ⋅ 100 g−1), but to a level less than stimulated by adenosine (750 ml ⋅ min−1 ⋅ 100 g−1). At all RV work loads, LV flow remains at two-thirds RV flow. Resting myocardial flow levels in fetuses that have been chronically hypoxemic are similar to maximal adenosine-stimulated flows of normal fetal sheep. This flow augmentation is evidently due to vascular remodeling because a normal “flow reserve” of ∼500 ml ⋅ min−1 ⋅ 100 g−1 during adenosine administration remains. Acute hypoxemia stimulates myocardial flow to extraordinary levels (>1.5 l ⋅ min−1 ⋅ 100 g−1), levels larger than can be obtained with chemical dilation alone. LV flows do not exceed adenosine-stimulated flows when nitric oxide synthase is antagonized. We conclude 1) fetal RV coronary flow increases with RV work but to levels less than during adenosine stimulation; 2) the fetal heart is designed to accommodate extremely high flows in response to acute hypoxemia, partially through large production of nitric oxide; and 3) the fetal coronary tree is dramatically remodeled in response to chronic hypoxemia.

Abstract:
An autoethnographic narrative is used to report qualitative changes in an Alzheimer's patient living in a home-care environment. The success of a simple dance activity that was used to cultivate an optimal level of flow between mother and daughter is described. Flow theory, although never mentioned, is implicit in the writing. Implications for future interventions with Alzheimer's patients by drawing on past-leamed neuromuscular patterns that elicit feelings of joy are suggested. Narrative is an evocative representation of positive interactions with Alzheimer's patients.

Abstract:
With corporate cash holdings on the rise, stakeholders need to know, among other things, what informs the companies’ cash holding policies and whether there are any benefits to be derived from piling up these cash reserves. Studies conducted in developed countries have identified the following as determinants of corporate cash holdings: firm size, growth opportunities, liquid asset substitutes, capital expenditure, leverage, dividend payments, cash flows and cash flow volatility. Few studies have focused on what drives firms’ cash holdings behavior in emerging economies. This study, the first of its kind, investigated the determinants of corporate cash holdings in the South African retail industry. The paper used panel data analysis to test the relationships between cash holdings level and the identified determinant factors. The authors found evidence that liquid asset substitutes, capital expenditure, dividend payments and cash flow volatility significantly influence the cash holdings levels of retail firms listed on the Johannesburg Stock Exchange.

Abstract:
Two-phase flows are encountered in a wide range of applications both on-ground and in space. The dynamics of such flows in the absence of gravity is completely different from that in normal gravity due to the absence of buoyancy forces. A deeper understanding of the behavior of multiphase flows is essential in order to improve the operation of devices which require the use of two-phase systems. Analytical and experimental work is still needed for enhancing the control of two-phase flows, due to the theoretical complexity and the lack of experimental data for certain configurations. In this work, the behavior of two-phase flows has been studied experimentally in normal gravity and in microgravity conditions. In particular, the single-jet configuration has been investigated for bubbly jets and droplet jets. Dynamics of individual bubbles and droplets as well as the global structure of the jets has been considered. The opposed-jet configuration has been investigated for bubbly flows. Different separation between jets and orientation angles have been studied in normal gravity, and the obtained results have been compared to the microgravity case. A numerical model has been implemented to study single-phase jet impingement and opposed bubbly jets at different gravity levels. Good qualitative agreement between the simulations and the experiments has been obtained. The bubble bouncing process, prior to coalescence, after collision with a flat free surface has been also studied experimentally in normal gravity conditions. The results presented in this work will help to improve the general understanding of two-phase flows in normal gravity and in microgravity conditions, with general applications on mixing devices, environmental and propulsion systems.

Abstract:
Fibroblasts are a type of cell which forms the structural framework of the connective tissue and are key players of wound closure, fibrosis and cancer. These cells experience mechanical perturbations due to matrix remodelling and interstitial fluid movement. Chemical signals from the tissue microenvironment such as Transforming growth factor β1 (TGF-β1) promote differentiation of fibroblasts to a myofibroblastic phenotype marked by enhanced expression of α-smooth muscle actin (α-SMA) rich stress fibres. However most of the evidence for this has been derived in static cultures which do not fully recapitulate the mechanically dynamic environment in vivo. The response of primary human fibroblasts to physiological levels of fluid movement and chemical perturbations from TGF-β1 is examined in this study. Findings show that fluid flow induced widespread changes in gene expression compared to static cultures and up-regulated genes such as α-SMA and Collagen 1A1. Surprisingly the combination of flow and exogenous TGF-β1 resulted in reduced myofibroblast differentiation. Myofibroblastic differentiation under flow was partially inhibited by follistatin-288 and blocked by TGF-β1 supplementation. This was associated with caveolin-mediated internalisation of TGF-β receptor type II. These findings suggest that fluid flow modulates fibroblast response to pro-differentiation signals such as TGF-β1. We propose that this may be a novel mechanism by which mechanical forces buffer responses to chemical signals in vivo, maintaining a context-specific fibroblast phenotype.

Abstract:
Purpose - The purpose of this thesis is to identify factors that have an impact on supermarket inventory levels that supply a manufacturing line and investigate how the impact of these factors can be controlled. In order to fulfill the purpose it was broken down into two research questions.   What factors have an impact on supermarket inventory levels supplying a manufacturing line? 2.      How can the impact of these factors be controlled? Method - To answer the research questions a literature study and a case study were conducted. The empirical findings from the case study and the literature study were used to find the answer to the first research question. The identified factors in the first research question were then analysed with the theoretical framework in order to answer the second research question. Different techniques have been used in order to collect necessary data including documentation studies, interviews, observations and basic training in the case company’s procurement system (GILM).   Findings - Total safety lead time, firm time and shortage impact were discovered during the case study. These factors were not to found during the literature study because they were specific parameters that are predetermined in the case company’s procurement system. Internal material handling and supermarket order quantity were factors also found during the case study. The identified factors are divided after which tool or method that can be used to gain control over the factor. Four different tools have been identified as solutions to gain control over the internal material handling. The factors that only have one identified tool as a solution are either case specific or not attentive in the theoretical framework as the other tools.   Implications - The identified factors from the literature study are considered as common factors that can be applied for companies that have a supermarket inventory. If manufacturing companies are facing problems with their supermarket inventory levels they can increase control by investigating the tools and methods presented in this thesis. Contributions - The factors that were identified during the case study have contributed with new discoveries in the field of study, since there is limited research done in this subject regarding supermarket systems.   Research limitations - More case studies could have been performed at similar companies, in order to investigate how generalizable the answers to both research questions are.

Abstract:
Doutoramento em Biologia<br>Cadmium is considered one of the most toxic metals to aquatic organisms. This naturally occurring metal is found in the environment in low concentrations due to natural processes, such as volcanic eruptions, natural crust erosion and also anthropogenic activities, such as mining and smelting. As a by-product of zinc mining, cadmium can reach aquatic environment through leaching or to rainwater runoff from the mine areas. It is a non-essential metal for organisms that even at relatively low concentrations can be toxic and may cause adverse effects due to its high bioaccumulation tendency. Considering this, the objective of this work was to study the toxicity and bioaccumulation potential of cadmium within different model marine trophic levels. To achieve this goal, this work was divided into four studies: i) assess the eco- and genotoxicity of cadmium to three marine test-species, representing different marine trophic levels, ii) determine the bioconcentration potential of cadmium in the calanoid copepod Acartia tonsa under different environmental conditions, such as pH, salinity and temperature, iii) evaluate the uptake and depuration kinetics of cadmium by the estuarine ditch shrimp Palaemon varians considering three different uptake routes: water, diet, water + diet and iv) assess the bioaccumulation patterns of cadmium in the Senegalese sole Solea senegalensis, a final consumer, and the possible risk and implications the consumption of the edible fraction of both shrimps and fish may bear to human health upon Cd exposure. We observed that the toxicity of cadmium is highly influenced by its speciation. Highest sensitivity to cadmium was observed by A. tonsa while the most sensitive endpoint was the Larval Development Ratio (LDR). Cadmium induced DNA damage to all species with increasing concentrations. The bioconcentration of cadmium by A. tonsa is strongly affected by different environmental conditions due to biological processes. The simultaneous exposure of P. varians to cadmium-contaminated water + diet showed that cadmium internal concentration was higher when compared to the individual pathways. Finally, by exposing S. senegalensis for 14 days through contaminated water and diet (supplied as Hediste diversicolor), with another 14 days of depuration phase, it was concluded that the 14 days of exposure were not enough for the fish to reach a steady state on cadmium internal concentration, and neither the 14 days of elimination were sufficient to cause total depuration of the accumulated cadmium in any of the organs. Moreover, a higher concentration of cadmium was found in the intestine of the fish when compared with the rest of the organs, and the elimination rate constant of cadmium in the liver was nule. The Target Hazard Quotient (THQ) and the Estimated Weekly Intake (EWI) values for cadmium for the edible fraction of S. senegalensis were below the acceptable levels set by the European Regulation while for the shrimps both THQ and EWI exceeded the acceptable levels established<br>O cádmio é considerado um dos metais mais tóxicos para organismos aquáticos, podendo ocorrer naturalmente no ambiente em concentrações muito baixas, devido a processos naturais (e.g., erupções vulcânicas, erosão da crosta natural) mas também devido a atividades antropogénicas, como a atividade mineira. Como um subproduto da exploração mineira de zinco, o cádmio pode ser libertado para o ambiente aquático através de lixiviação ou escorrências. O cádmio é um metal não essencial para os organismos mas, mesmo em concentrações relativamente baixas, pode ser tóxico, provocando efeitos adversos devido à sua elevada tendência para bioacumular. Neste contexto, o objetivo deste trabalho foi estudar a transferência de cádmio em diferentes modelos de níveis tróficos marinhos. O estudo foi dividido em quatro etapas: i) avaliar a eco- e genotoxicidade de cádmio em três espécies marinhas, representando diferentes níveis tróficos marinhos ii) determinar a bioconcentração de cádmio por Acartia tonsa sob diferentes condições ambientais, tais como pH, salinidade e temperatura, iii) a avaliação de toxicocinética de cádmio pelo camarão estuarino Palaemon varians sob três vias de exposição diferentes: água, alimentação e água + alimentação, e iv) avaliar os padrões de bioacumulação de cádmio no linguado Solea senegalensis como consumidor final, e os possíveis riscos e implicações do consumo da fração edível de camarões e peixe que pode ter para a saúde humana, após a exposição a cádmio. Foi observado que a toxicidade de cádmio é influenciada pela sua especiação. A maior sensibilidade ao cádmio foi observada em A. tonsa tendo como parâmetro mas sensível o Índice de Desenvolvimento Larvar (LDR). O cádmio induziu danos no ADN de todas as espécies utilizadas. A bioconcentração de cádmio por A. tonsa é fortemente afetada por diferentes condições ambientais devido a processos biológicos. P. varians foi exposto a cádmio através de diferentes vias de exposição: água ou alimento ou água e alimento. A exposição simultânea de P. varians a água e alimento contaminado com cádmio mostrou que a concentração interna de cádmio foi maior quando comparada com as outras duas vias de exposição. Finalmente, mesmo uma exposição através de água e alimento contaminado (fornecido como Hediste diversicolor) não foi suficiente para que o peixe S. senegalensis atingisse um plateau na concentração interna de cádmio, sendo os 14 dias de depuração insuficientes para que os organismos depurassem totalmente a concentração interna que havia sido acumulada. Adicionalmente, foi encontrada uma maior concentração de cádmio no intestino de S. senegalensis quando comparada com os outros órgãos, e a constante de eliminação de cádmio no fígado foi inexistente. Os valores do Coeficiente de Perigo Alvo (THQ) e o Consumo Semanal Estimado (EWI) para o cádmio estavam abaixo dos níveis aceitáveis estabelecidos em regulamentos europeus para a fração edível de S. senegalensis, enquanto que para P. varians tanto o THQ quanto o EWI excederam os níveis aceitáveis estabelecidos.

Abstract:
The effect of a heat-killed, unencapsulated strain of type III group B streptococcus (GBS), COH 1-13, on cerebral blood flow (CBF) and prostanoid production was investigated in two separate piglet models. In the first model, we examined the temporal profile of changes in CBF and cerebrospinal fluid cytochemistry in response to GBS challenge during a 6 hour study period. Despite marked leukocytosis at 6 hours, GBS did not significantly affect CBF and other cardiovascular parameters, hematology and cerebral prostanoid production. In the second model, we evaluated the early effect of GBS on CBF autoregulatory function and subsequently employed pharmacologic agents to inhibit the effect of GBS. Cerebral perfusion pressure (CPP) was altered by inflating balloon-tipped catheters placed at the aortic root to produce cerebral hypotension and at the descending aorta to produce cerebral hypertension. Piglets inoculated with GBS exhibited a narrow range of CBF autoregulation due to an impairment at the upper limit of CPP, which was prevented by treatment with dexamethasone or ibuprofen. Cerebral prostanoid production did not change significantly with adjustments in CPP between the various treatment groups. We conclude that GBS may impair CBF control without affecting cerebral prostanoid production and may increase the risk of brain damage in neonates with bacterial meningitis.

Abstract:
In order to attract pedestrians to travel with public transport instead of private cars, the layout of interchange stations is important and should be designed in an effective way. Microscopic simulation of pedestrians can be used to evaluate different layout scenarios or a future increase in flow. The simulation software Viswalk was investigated, where the movements of pedestrians are based on a social force model,. The purpose of this thesis was to investigate simulated walking speeds for different flow levels and to investigate the effects of dividing pedestrians into types with different desired speeds. The aim was to find a desired speed distribution that can be used for different flow levels. Field studies have been performed to collect pedestrian traffic data with a video camera at Stockholm Central Station. Two disjoint flow levels were identified and used to investigate if the same desired speed distribution could be used for different flow levels. The average observed walking speed was 1.33 metres per second at the low flow level and 1.25 metres per second at the high flow level. The error was 4.5 percent between the average observed walking speed and the average simulated walking speed when the optimal desired speed distribution at the low flow level was used at the high flow level. Effects of using different desired speed distributions for different pedestrian types have also been investigated. The error between the average of the observed and the simulated walking speeds varies between 2.3 and 4.1 percent when dividing pedestrians into different types when the optimal desired speed distributions at the low flow level are used at the high flow level. A sensitivity analysis of some parameters of the social force model in Viswalk has also been performed. Several adjustments of the parameters show that some parameters had great impact of the simulated walking speeds. The final conclusion is that the parameter configuration and how the pedestrians are divided into different types affect the average simulated walking speed.

Abstract:
This report summarizes discharge and water quality monitoring data for the Snake River and Jackson Lake reservoir levels in Grand Teton National Park and John D. Rockefeller, Jr. Memorial Parkway for calendar year 2016. Annual and long-term discharge summaries and an evaluation of chemical conditions relative to state and federal water quality standards are presented. These results are considered provisional, and may be subject to change. River Discharge: Hydrographs for the Snake River at Flagg Ranch, WY, and Moose, WY, exhibit a general pattern of high early summer flows and lower baseflows occurring in late summer and fall. During much of 2016, flows at the Flagg Ranch monitoring location were similar to the 25th percentile of daily flows at that site. Peak flows at Flagg Ranch were similar to average peak flow from 1983 to 2015 but occurred eleven days earlier in the year compared to the long-term average. Peak flows and daily flows at the Moose monitoring station were below the long-term average. Peak flows occurred four days later than the long-term average. During summer months, the unnatural hydro-graph at the Moose monitoring location exhibited signs of flow regulation associated with the management of Jackson Lake. Water Quality Monitoring in the Snake River: Water quality in the Snake River exhibited seasonal variability over the sampling period. Specifically, total iron peaked during high flows. In contrast, chloride, sulfate, sodium, magnesium, and calcium levels were at their annual minimum during high flows. Jackson Lake Reservoir: Reservoir storage dynamics in Jackson Lake exhibit a pattern of spring filling associated with early snowmelt runoff reaching maximum storage in mid-summer (on or near July 1). During 2016, filling water levels and reservoir storage began to increase in Jackson Lake nearly two weeks earlier than the long-term average and coincident with increases in runoff-driven flows in the Snake River. Although peak storage in Jackson Lake was larger and occurred earlier than the long-term average, minimum storage levels were similar to the long-term average.

Abstract:
From 2012-13 to 2018-19, the number of Chicago Public Schools (CPS) high school students taking an introductory computer science course rose from three thousand per year to twelve thousand per year. Our analysis examines the policy entrepreneurship that helped drive the rapid expansion of computer science education in CPS, within the broader context of the development of computer science at the national level. We describe how actions at the national level (e.g., federal policy action and advocacy work by national organizations) created opportunities in Chicago and, likewise, how actions at the local level (e.g., district policy action and advocacy by local educators and stakeholders) influenced agenda setting at the national level. Data from interviews with prominent computer science advocates are used to document and explain the multidirectional (vertical and horizontal) flow of advocacy efforts and how these efforts influenced policy decisions in the area of computer science. These interviews with subsystem actors––which include district leaders, National Science Foundation program officers, academic researchers, and leaders from advocacy organizations––provide an insider’s perspective on the unfolding of events and highlight how advocates from various organizations worked to achieve their policy objectives.

Grossir, Guillaume. On the design of quiet hypersonic wind tunnels. Von Karman Institute for Fluid Dynamics, 2020. http://dx.doi.org/10.35294/tm57.

Full text
Abstract:
This document presents a thorough literature review on the development of hypersonic quiet tunnels. The concept of boundary layer transition in high-speed flows is presented first. Its consequences on the free-stream turbulence levels in ground facilities are reviewed next, demonstrating that running boundary layers along the nozzle walls must remain laminar for quiet operation. The design key points that enable laminar boundary layers and hypersonic operation with low free-stream noise levels are then identified and discussed. The few quiet facilities currently operating through the world are also presented, along with their design characteristics and performances. The expected characteristics and performances of a European quiet tunnel are also discussed, along with flow characterization methodologies and different measurement techniques. It is finally shown that the required expertise to establish the first European quiet hypersonic wind tunnel is mostly at hand.

Full text
Abstract:
In this report, we study the use of Multi-Level Monte Carlo (MLMC) methods for time dependent problems. It was found that the usability of MLMC methods depends strongly on whether or not the underlying time dependent problem is chaotic in nature. Numerical experiments are conducted on both simple problems, as well as fluid flow problems of practical interest to the ExaQUte project, to demonstrate this. For the non-chaotic cases, the hypotheses that enable the use of MLMC methods were found to be satisfied. For the chaotic cases, especially the case of high Reynolds’ number fluid flow, the hypotheses were not satisfied. However, it was found that correlations between the different levels were high enough to merit the use of multi-fidelity or control-variate approaches. It was also noted that MLMC methods could work for chaotic problems if the time window of analysis were chosen to be small enough. Future studies are proposed to examine this possibility.

May, David, David Biedenharn, Tate McAlpin, and Ty Wamsley. Hydraulic dike effects investigation on the Mississippi River : Natchez to Baton Rouge. Engineer Research and Development Center (U.S.), 2021. http://dx.doi.org/10.21079/11681/40539.

Full text
Abstract:
This report documents an investigation of the hydraulic effects of dikes on water levels in the Mississippi River between Natchez, MS, and Baton Rouge, LA, conducted for the U.S. Army Corps of Engineers, Mississippi Valley Division, Vicksburg, MS. The investigation was conducted using a previously calibrated Natchez-to-Baton Rouge Adaptive Hydraulics numerical model. The objectives were to alter roughness and height variables associated with the dikes and overbanks encompassed in the numerical model and evaluate their effects on water surface elevations. This academic exercise provides an indication of the relative level of impact associated with modifications to the dikes and overbanks for this portion of the Mississippi River and does not represent future plans or recommendations by the U.S. Army Corps of Engineers. Steady flow simulations were simulated for 12 May 2011 to investigate the variation in model results during the peak of the 2011 flood on the Mississippi River.

Abstract:
This paper analyzes how labor ows respond to permanent idiosyncratic shifts in rm-level production functions and demand curves using very detailed Swedish micro data. Shocks to rms physical productivity have only modest eects on rm-level employment decisions. In contrast, the paper documents rapid and substantial employment adjustments through hires and separations in response to rm-level demand shocks. The choice of adjustment margin depends on the sign of the shock: rms adjust through increased hires if these shocks are positive and through increased separations if the shocks are negative.
