Résumé :
The initial ‘idea’ for the book emerged during the seminar Sharing of Innovative Pedagogical Practices that occurred at the University of Coimbra (Portugal) in 2018. Like all ‘good ideas’, this one originated in a conversation between colleagues from the University of Coimbra and the University of West London in the United Kingdom. The ‘idea’ of this book was to move away from sharing experiences related to teaching and learning in higher education in just one or two countries, but instead to organise a more European view about the policy, research and teaching practices that are shaping the way our students learn, academics teach and do research. We have a total of 16 chapters from academics in Portugal, the United Kingdom, Ireland, Sweden, the Netherlands, Spain, Italy, and the Czech Republic.<br>The book is organised in four interrelated themes: (1) policy and quality; (2) professionalisation of teaching and academic development; (3) research and teaching nexus; and (4) pedagogy and practice. <br>Enjoy reading the book!

Texte intégral
Résumé :
Various forms of academic co-operation criss-cross the modern university system in a bewildering number of ways, from the open exchange of ideas and knowledge, to the sharing of research results, and frank discussions about research challenges. Embedded in these scholarly networks is the question of whether a global template for the management of both higher education and national research organisations is necessary, and if so, must institutions slavishly follow the high-flown language of the global knowledge society or risk falling behind in the ubiquitous university ranking system? Or are there alternatives that can achieve a better, more ethically inclined, world? Basing their observations on their own experiences, an interesting mix of seasoned scholars and new voices from southern Africa and the Nordic region offer critical perspectives on issues of inter- and cross-regional academic co-operation. Several of the chapters also touch on the evolution of the higher education sector in the two regions. An absorbing and intelligent study, this book will be invaluable for anyone interested in the strategies scholars are using to adapt to the interconnectedness of the modern world. It offers fresh insights into how academics are attempting to protect the spaces in which they can freely and openly debate the challenges they face, while aiming to transform higher education, and foster scholarly collaboration. The Southern African-Nordic Centre (SANORD) is a partnership of higher education institutions from Denmark, Finland, Iceland, Norway, Sweden, Botswana, Namibia, Malawi, South Africa, Zambia and Zimbabwe. SANORDs primary aim is to promote multilateral research co-operation on matters of importance to the development of both regions. Our activities are based on the values of democracy, equity, and mutually beneficial academic engagement.

Résumé :
Purpose: 0.9% sodium chloride IV fluid (normal saline) is critical in a clinical setting and may save lives. Data on thermal stability of normal saline, in out-of-hospital settings, are lacking. The purpose of this study was to evaluate the effect of temperature on normal saline stability. Method: Normal saline provided in flexible plastic containers (Qatar Pharma, BA:1929013008, n=96) were stored at constant temperature of 22, 50, or 70°C, and at cyclic temperature of 70°C for 8 hours and 22°C for 16 hours for a period up to 28 days. The containers were sampled at 0, 12, 24, 48 and 72 hours and at 1, 2, 3, and 4 weeks in the short- and long-term study, respectively. Fluid inside containers was evaluated for discoloration, turbidity, bulging, and pH. A 1 mL of normal saline was withdrawn from each container and stored at 4°C until analysis. A 20 µL was diluted in 12 mL distilled water to be injected into ion exchange chromatography instrument (Metrohm, 850 Professional IEC) for the measurement of sodium and chloride levels. Results: Discoloration or turbidity of normal saline fluid was not observed at any temperature or exposure period. The container slightly bulged at 50˚C and largely bulged at 70˚C & cyclic. The pH was 5.59±0.08 at 22˚C, 5.73±0.04 at 50˚C, 5.86±0.02 at 70˚C and 5.79±0.03 at cyclic. Remaining sodium and chloride levels ranged from 100.2±0.26% to 111.27±4.22% and from 99.04±0.76 to 110.95±2.62%, respectively. Conclusion: Normal saline containers are stable up to 4 weeks under simulated constant and cyclic high temperatures. Storage in the cabinet of ambulance vehicles during hot summer season in an arid country like Qatar is to be assessed in real-life conditions.

Résumé :
Cutting transport is one of the major factors, which affects the cost, time and quality of drilling operations. Over the years, as the number of directional wells have increased to improve the productivity, it has been observed that cutting transport is more difficult in horizontal and directional wells as compared to vertical wells. While the foam/aerated drilling fluid provides significant advantages over conventional drilling fluid such as higher rate of penetration and reduction in formation damage, however these advantages are reduced due to inefficient cutting transport to the surface. This study investigates the effect of different parameters such as cuttings weight concentration, liquid flow rate and gas flow rate on cutting transport using foam/aerated drilling fluid. The experiments were conducted in a 6.16 m long horizontal pipe with 2.5 in. inner diameter and 4.5 in. outer diameter and annular diameter ratio of 1.8. The liquid and the gas flow rate was varied between 219 – 380 kg/min and 4 – 6.5 L/min, while the gas input pressure was kept constant at 2 bar. An anionic surfactant was used to stabilize the foam with a stationary liquid density of 818 kg/m3. The concentration of the borosilicate solid glass beads of 2-3 mm average diameter was varied between 0 – 4 wt. %. The results showed that increase in the liquid flow rate or Reynold number improved cutting transport, whereas increase in the gas flow rate and solid cuttings concentration decreased the cutting transport velocity for a constant gas input pressure. A non-dimensional performance parameter was introduced, for comparison of the cutting transport efficiency of different fluids such as water, 0.05 wt. % and 0.1 wt. % bio-polymer concentrations. It was observed that foam fluid has the highest bed height, Reynold number and lowest solid velocity (Reynold number). Performance parameter indicates that foam fluid has a better cutting transport efficiency as compared to bio-polymer based drilling fluid for horizontal drilling. This study can act as a guide to improve our knowledge of cutting transport and how cutting transport efficiency of different fluids can be compared using performance parameter.

Résumé :
As part of the Norfolk-Southern Railroad’s on-going investigation into fuel consumption reductions for their fleet of 3000 locomotives, the Center for Alternative Fuels, Engines and Emissions at West Virginia University conducted on-site locomotive engine performance and emissions measurements to characterize the performance, fuel consumption and emissions associated with fuel injectors from two injector suppliers. Emissions and fuel consumption were measured using the West Virginia University Transportable Locomotive Emissions Testing Laboratory, which was set up at the Norfolk-Southern Heavy Repair Facility in Roanoke, Virginia. The tests were conducted to evaluate potential emissions and fuel consumption differences between two fuel injector suppliers using an EMD GP38-2 locomotive equipped with a 2100 hp (1566 kW), 16-cylinder, EMD 16-645E engine. The test locomotive engine was freshly overhauled and certified to the EPA locomotive Tier 0 emissions standards. Emissions and fuel consumption measurements were conducted according to the Federal Test Procedures defined in the Code of Federal Regulations 40CFR Part 92 Subpart B [1]. The engine was first tested in the “as overhauled” configuration with the OEM fuel injectors to establish the baseline emissions and fuel consumption. The baseline FTP results confirmed that this locomotive was in compliance with the Federal Tier 0 emissions standards. The OEM specification fuel injectors were replaced with “Fuel Saver” injectors designed and manufactured by an aftermarket injector supplier referred to in this paper as Supplier B. The Supplier B injectors reduced fuel consumption on the average of 2–4% for each notch, except for Notch 4 and Low Idle. However, the Supplier B injectors increased the NOx levels by 20–30% for almost every notch, which is an expected result due to the improved combustion efficiency.

Résumé :
A thrust compounded helicopter - a main rotor with a trailing propeller was tested in the Glenn L. Martin Wind Tunnel (GLMWT) to evaluate its performance under different flight conditions. The main rotor rig consists of a hingeless hub with four fully instrumented NACA 0012 blades and a modified Robin fuselage. The propeller rig consists of a rigid Sensenich L26H propeller with four blades. Tunnel tests were carried out for the isolated propeller, and thrust compounded rotor configurations. The isolated propeller tests were conducted with and without the fuselage installed ahead of it to understand the effects of the fuselage on propeller performance. The thrust compound configuration was tested at three different main rotor shaft tilt angles (αs): -4°, 0°, and 4°, advance ratios (μ) from 0.3 to 0.6, and multiple lift (CL/σ) and propulsive (CX/σ) trim targets. Main rotor hub loads, oscillatory blade structural loads, and propeller hub loads were measured for all the tests. The test data was verified with a full vehicle aeromechanical analysis using the University of Maryland Advanced Rotorcraft Code (UMARC). The thrust compound configuration with the main rotor shaft tilt of -4° (rearward tilt) provided the best performance. Thrust compounding with rearward shaft tilt (-4°) resulted in a 50% increase in the maximum aircraft lift-to-drag ratio compared to a single rotor helicopter. Half peak-to-peak hub vibratory loads and blade bending loads decreased with thrust compounding. It was observed that for the same lift target (CL/σ), thrust compounding achieved 20% higher flight speeds than a single rotor.

Résumé :
As part of the “ESA_Lab@" initiative, a Concurrent Engineering facility has been constructed at the Mechanical Engineering department of Technical University Darmstadt. Concurrent Engineering is a well-proven concept for designing complex space systems and missions in the pre-phase 0/A mission phase. The Concurrent Engineering methodology and processes are enabled by a multidisciplinary team and specific infrastructure in terms of both hardware and software, which generate an effective and time efficient design management system. The university’s “Concurrent Engineering Lab” provides an environment for both researchers and students to explore and apply the Concurrent Engineering approach in areas such as (model-based) systems engineering, Industry 4.0/ Space 4.0, and space traffic management. Furthermore, collaboration with the European Space Operations Centre – also located in Darmstadt – regarding the application of Concurrent Engineering for Ground Segment & Operations has been started. The first addition to the university’s curriculum centered around the Concurrent Engineering Lab will be a “Concurrent Engineering Tutorial”, an opportunity to introduce the Concurrent Engineering methods and tools via hands-on experience to students of the newly established master’s degree program “Aerospace Engineering”. “Tutorials” are elective block courses of the degree program which offer practical learning experiences in many different fields, awarding 4 credit points upon successful completion. Building on the lectures "Fundamentals of Space Systems" and "Space Systems and Space Operations", the week-long “Concurrent Engineering Tutorial” will challenge students to use their acquired knowledge to develop a preliminary design for a predefined CubeSat mission. This Tutorial will not only provide a closer understanding of the individual subsystems of the space segment of a mission, the Concurrent Engineering process and the relevant software “COMET” by RHEA Group but will also create a synergy with a student association of the university, as one of their projects is the development of a CubeSat. This paper describes the background and approach to the development of the Tutorial, in particular the structure of the re-usable model architecture in “COMET”, which was specifically derived and implemented for this purpose and validated via a pilot study

Aims and Objectives: To determine and evaluate the difference/s, in terms of tumor control and side effects, between weekly and three weekly cisplatin concomitant with external beam radiotherapyfor locally advanced carcinoma of cervix. Materials and Methods: The study was conducted in Radiotherapy Department, University of Health Sciences, Rohtak (India), on sixty previously untreated, histopathologically proven patients of locally advanced carcinoma of uterine cervix. The patients were treated with External Beam Radiotherapy (EBRT) 50 Gy/25 fractions over 5 weeks and concomitant cisplatin, followed by intra-cavitary HDR brachytherapy (ICBT) 700 cGy to point A; three times, once in a week. The patients were assigned randomly either of two groups of 30 patients each. In Group I (Study Group) the patients received three weekly cisplatin 75 mg/m2 for 2 cycles whilein Group II (Control Group) the patients received weekly cisplatin 40 mg/m2 for 5 cycles. Evaluation of response and toxicity was done weekly during treatment and monthly thereafter up to six months. The data thus obtained was assessed and analysed using LaMorte statistical tool. The study was approved by Ethical Committee of the institute and quality was periodically monitored by senior consultant and guide. Results: Stage wise disease response in study and control respectively at the end of treatment was as follows: Stage IIA - CR (80% vs 100%), PR (20% vs 0%); Stage IIB - CR (80% vs 76.47%), PR (20% vs 23.53%); Stage IIIA - CR (60% vs 100%), PR (40% vs 0%); Stage IIIB - CR (60% vs 60%), PR (40% vs 20%), NR(0% vs 20%). Stage wise disease status at the end of sixth month follow up was as follows: Stage IIA – NED (80% vs 100%), RD (20% vs 0%); Stage IIB - NED (80% vs 76.67%), RD (20% vs 23.53%); Stage IIIA - NED (60% vs 100%), RD (40% vs 0%); Stage IIIB - NED (60% vs 60%), RD (40% vs 40%). Tumor response was not significantly different in the two groups with respect to age distribution, rural/urban distribution, histopathological distribution and treatment interruption. Maximum level of hematological toxicity (WHO criteria) observed in study and control group respectively at the end of treatment was as follows: Anaemia; Grade II - 4 (13.33%) in both the groups, leukopenia; Grade II – 1 (3.33%) vs 0 (0%). The worst acute skin reactions observed by the end of treatment in Group I and II respectively were Grade II – 2 (6.67%) vs 0 (0%). The worst acute mucosal reactions were Grade II - 5(16.66%) vs 0 (0%). Upper gastrointestinal toxicity (Grade II & III) was 16.7% versus 13.3% respectively. Lower gastrointestinal toxicity (Grade II & III) was 30.0% versus 36.7%. No significant weight loss was observed in either of the groups. Though, all the patients completed the intended treatment, treatment interruption for more than a week was observed in 10 (33.33%) vs 8 (26.67%) patients respectively, due to acute toxicities. Conclusion: Three weekly cisplatin, concomitant with radiation seems to be the potential, effective and acceptable alternate as standard of treatment for locally advanced carcinoma cervix; especially for increased work load and limited resource setups.

Résumé :
Photocatalyst such as Titanium Dioxide (TiO2) has been recently introduced as a nanoparticle into cementitious permeable pavements. Combining photocatalytic compounds within concrete permeable pavements can aid with depollution of several contaminants found in urban water streams and air impurities. This paper presents research carried out at the University of Greenwich, UK using photocatalytic concrete with varying percentages of TiO2 (0 %, 1% and 5%) to assess the levels depollution which can be achieved. Concrete samples were testing against the degradation of 2, 4-Dichlorophenoxyacetic Acid, a harmful chemical found in herbicides. This advanced oxidation process can aid in the reduction of urban pollution from an air and water perspective, improving sustainability for urban cities. Self-cleaning benefits of photocatalytic concrete permeable pavements can be used to keep urban infrastructure cleaner and more aesthetically pleasing. Experimental tests were carried out on the characterisation of inorganics through X-Ray diffraction and Fourier Transform Infrared Spectroscopy to ensure that the structures of the concrete samples were not altered by addition of the nanoparticles (photocatalyst). Experimental results were compared to that found in previous literature and confirmed that the addition of 5% TiO2 did not affect the structure of the concrete samples and can be a viable option used in urban infrastructure such as permeable pavements.

Résumé :
Abstract Low Reynolds number flow (Re = 100) over a slitted 2D cylinder was examined to analyze the flow characteristics within the slit and the role it plays on the shedding frequency. The goal of this work is to explore the enhancement of the lift and reduction of the drag for energy harvesting purposes. One way of achieving this goal is by controlling the separation of the incompressible laminar boundary layer through blowing and suction. However, in this work it is passively controlled by the cylinder slit. Different slit orientation (azimuth angles: 0, π/12, π/6, π/4, 5π/12, and π/2) at 10% slit-to-diameter ratio was considered. The work was carried out numerically by seeking solution to the unsteady Navier-Stokes equations. Validation was done experimentally utilizing the 2D vertical soap film tunnel available in our laboratory at Khalifa University. The visualization in soap film tunnel exploits the optical properties of soap film and relies on the wake formation patterns and the frequency at which vortices shed using well developed imaging techniques. These flow visualizations of the vortex shedding behind the cylinder with and without slit were recorded and analyzed to infer its Strouhal number (St = f.D/U). From the common Roshko’s graph (Re vs St) the Reynolds number was determined, and the film property was evaluated. Using common flow as baseline the technique can be used to validate numerous 2D-flow simulations, airfoils, bluff bodies, and even the oscillating flow around them. The details of the soap-film technique and parameters for successful experimentation are provided and demonstrated on slitted cylinder. The results are validated using numerical technique and the results from the literature.

Résumé :
Background: COVID-19 had a huge impact on the wellbeing of healthcare workers (HCWs). This is well documented during the first peak of the pandemic. With cases in the UK rising for a third peak, hospitalisations and deaths surpassing the first, there is very little known about the mental health of HCWs during this time. Methods: Using a questionnaire, data was collected from patient-facing staff at Barking, Havering, and Redbridge University Trust to quantify and compare the period prevalence of symptoms of depression, anxiety, and PTSD during the first peak (P1: March-May 2020) and third peak (P3: December 2020-Feburary 2021) of the COVID-19 pandemic as well as wellbeing service use, demographics of responders and what they found most difficult during the peaks. Results: Of 158 responders, only 22·4% felt they had enough access to wellbeing services during P1 and 21·5% in P3. Of those who used wellbeing services 34·4% found them useful in P1 and 34·6% in P3. 70·3% of responders felt that not enough was done for staff wellbeing. The median anxiety score decreased from P1 (10(range 5-17)) to P3 (8(range 4-16)) p=0·031. Under 30-year-olds’ depression and PTSD scores increased from P1 to P3 (depression: P1 7(1-11), P3 8(3-14), p=0·048, PTSD: P1 4(0-7) peak 3 5(2-9), p=0·037). Several groups showed a decrease in anxiety scores from P1 to P3 including; over 30-year-olds (P1 10(5-17), P3 7(3-15) p=0·002), BME responders (P1 8(3·75-15) P3 6·5(1-12) p=0·006), AHP (P1 14(7-19), P3 11(5-19) p=0·005), ITU workers (P1 15(8-18·25) P3 12(5·75-18·25) p=0·004), and those who were redeployed (P1 8(5-18·25), P3 5(2-14·75), p=0·032). Conclusion: We have observed changes in mental health symptoms within the study population as the peaks of the pandemic continue. With the majority of responders reporting they felt not enough had been done for their wellbeing support - and of those who used the wellbeing services only around 1/3 felt they were useful - we hope that this paper can help inform wellbeing provision and identify groups at higher risk of developing mental health symptoms.

Elimination of emissions of ammonia and hydrogen sulfide from confined animal and feeding operations (CAFO) using an adsorption/liquid-redox process with biological regeneration.

Résumé :
The project was originally aimed at investigating and developing new efficient methods for cost effective removal of ammonia (NH₃) and hydrogen sulfide (H₂S) from Concentrated Animal Feeding Operations (CAFO), in particular broiler and laying houses (NH₃) and hog houses (H₂S). In both cases, the principal idea was to design and operate a dedicated air collection system that would be used for the treatment of the gases, and that would work independently from the general ventilation system. The advantages envisaged: (1) if collected at a point close to the source of generation, pollutants would arrive at the treatment system at higher concentrations; (2) the air in the vicinity of the animals would be cleaner, a fact that would promote animal growth rates; and (3) collection efficiency would be improved and adverse environmental impact reduced. For practical reasons, the project was divided in two: one effort concentrated on NH₃₍g₎ removal from chicken houses and another on H₂S₍g₎ removal from hog houses. NH₃₍g₎ removal: a novel approach was developed to reduce ammonia emissions from CAFOs in general, and poultry houses in particular. Air sucked by the dedicated air capturing system from close to the litter was shown to have NH₃₍g₎ concentrations an order of magnitude higher than at the vents of the ventilation system. The NH₃₍g₎ rich waste air was conveyed to an acidic (0<pH<~5) bubble column reactor where NH₃ was converted to NH₄⁺. The reactor operated in batch mode, starting at pH 0 and was switched to a new acidic absorption solution just before NH₃₍g₎ breakthrough occurred, at pH ~5. Experiments with a wide range of NH₃₍g₎ concentrations showed that the absorption efficiency was practically 100% throughout the process as long as the face velocity was below 4 cm/s. The potential advantages of the method include high absorption efficiency, lower NH₃₍g₎ concentrations in the vicinity of the birds, generation of a valuable product and the separation between the ventilation and ammonia treatment systems. A small scale pilot operation conducted for 5 weeks in a broiler house showed the approach to be technically feasible. H₂S₍g₎ removal: The main goal of this part was to develop a specific treatment process for minimizing H₂S₍g₎ emissions from hog houses. The proposed process consists of three units: In the 1ˢᵗ H₂S₍g₎ is absorbed into an acidic (pH<2) ferric iron solution and oxidized by Fe(III) to S⁰ in a bubble column reactor. In parallel, Fe(III) is reduced to Fe(II). In the 2ⁿᵈ unit Fe(II) is bio-oxidized back to Fe(III) by Acidithiobacillus ferrooxidans (AF).In the 3ʳᵈ unit S⁰ is separated from solution in a gravity settler. The work focused on three sub-processes: the kinetics of H₂S absorption into a ferric solution at low pH, the kinetics of Fe²⁺ oxidation by AF and the factors that affect ferric iron precipitation (a main obstacle for a continuous operation of the process) under the operational conditions. H₂S removal efficiency was found higher at a higher Fe(III) concentration and also higher for higher H₂S₍g₎ concentrations and lower flow rates of the treated air. The rate limiting step of the H₂S reactive absorption was found to be the chemical reaction rather than the transition from gas to liquid phase. H₂S₍g₎ removal efficiency of >95% was recorded with Fe(III) concentration of 9 g/L using typical AFO air compositions. The 2ⁿᵈ part of the work focused on kinetics of Fe(II) oxidation by AF. A new lab technique was developed for determining the kinetic equation and kinetic parameters (KS, Kₚ and mₘₐₓ) for the bacteria. The 3ʳᵈ part focused on iron oxide precipitation under the operational conditions. It was found that at lower pH (1.5) jarosite accumulation is slower and that the performance of the AF at this pH was sufficient for successive operation of the proposed process at the H₂S fluxes predicted from AFOs. A laboratory-scale test was carried out at Purdue University on the use of the integrated system for simultaneous hydrogen sulfide removal from a H₂S bubble column filled with ferric sulfate solution and biological regeneration of ferric ions in a packed column immobilized with enriched AFbacteria. Results demonstrated the technical feasibility of the integrated system for H₂S removal and simultaneous biological regeneration of Fe(III) for potential continuous treatment of H₂S released from CAFO. NH₃ and H₂S gradient measurements at egg layer and swine barns were conducted in winter and summer at Purdue. Results showed high potential to concentrate NH₃ and H₂S in hog buildings, and NH₃ in layer houses. H₂S emissions from layer houses were too low for a significant gradient. An NH₃ capturing system was designed and tested in a 100-chicken broiler room. Five bell-type collecting devices were installed over the litter to collect NH₃ emissions. While the air extraction system moved only 10% of the total room ventilation airflow rate, the fraction of total ammonia removed was 18%, because of the higher concentration air taken from near the litter. The system demonstrated the potential to reduce emissions from broiler facilities and to concentrate the NH₃ effluent for use in an emission control system. In summary, the project laid a solid foundation for the implementation of both processes, and also resulted in a significant scientific contribution related to AF kinetic studies and ferrous analytical measurements.
