Nelson, Kent R. "Lateral Resistance of Piles Near Vertical MSE Abutment Walls at Provo Center Street." BYU ScholarsArchive, 2013. https://scholarsarchive.byu.edu/etd/3926.

Full text
Abstract:
Full scale lateral load tests were performed on four piles located at various distances behind MSE walls. Three of the four test piles were production piles used to support bridges, and the other pile a production pile used as part of the bridge abutment. The objective of the testing was to determine the effect of spacing from the wall on the lateral resistance of the piles and on the force resisted by the MSE reinforcement. Lateral load-displacement curves were developed for pile at various spacing and with various reinforcement ratio (reinforcement length, L divided by wall height, H). The force in the reinforcement was measured using strain gauges. Lateral load analyses were performed to determine the minimum spacing required to eliminate any effect of the wall on the pile resistance (p-multiplier of 1) and the reduction in soil resistance at closer spacings (p-multiplier less than 1). With the addition of the data fro Price (2012) tentative curves have been developed showing p-multiplier vs. normalized spacing behind wall for a length to height ratio of 1.6, 1.2, and 1.1. The data suggest that with a L/H ratio of 1.6, a p-multiplier of 1 can be used when the normalized distance from the back face of the MSE wall to the center of the pile is at least 3.8 pile diameters. When the L/H ratio decreases to 1.2 and 1.1 a p-multiplier of 1 can be used when the pile is at least 4.5 and 5.2 pile diameters behind the wall respectively. For smaller spacings, the p-multipliers decreased essentially linearly with normalized distance from the wall. A plot showing the increased load in the reinforcement as a function of distance from the pile has been developed. The data in the plot is normalized to the maximum lateral load and to the spacing from the wall to the pile. The best fit curve is capped at a normalized tensile force of approximately 0.12. The data show that the increase in tensile force on the reinforcement when a lateral load is applied to the piles decreases exponentially as the normalized distance from the pile increases. The plot is limited to the conditions tested, i.e. for the reinforcement in the upper 3 ft. of the wall with L/H values at 1.2.

Hansen, Felicia. "Toys''R''Cloth : An alternative interpretation of Kente cloth." Thesis, Högskolan i Borås, Akademin för textil, teknik och ekonomi, 2020. http://urn.kb.se/resolve?urn=urn:nbn:se:hb:diva-23505.

Full text
Abstract:
This degree work places itself within the field of textile design, with an artistic approach. The motive with this work is to introduce Kente cloth as a textile expression to be developed as a contemporary textile technique. The aim is to explore ways of reinterpreting the West African weaving technique of Kente cloth in combination with the use of recycled toys in order to create contemporary artistic textile designs. The design method consisted of workshops that focused on the deconstruction of the technique and the categorisation of toys. Experimental sketches on the handloom and jacquard machine were produced. The outcome of this design work is a collection of three handwoven artistic textile designs. Toys’’R’’Cloth engages the viewer to produce more sustainable designs by using recycled toys as material reuse. This work and its design method have the potential to be developed further and applied onto other textile techniques.

Pearce, Catherine Anne. "Behaviour and other indices of welfare in growing/finishing pigs kept on Straw Flow, bare concrete, full slats and deep-straw." Thesis, University of Aberdeen, 1993. http://digitool.abdn.ac.uk/R?func=search-advanced-go&find_code1=WSN&request1=AAIU547999.

Full text
Abstract:
The current trends in the intensive production of growing/finishing pigs are to devise alternative systems which help to improve welfare by the provision of a malleable substrate, such as straw, in order that the pigs can carry out natural behaviour. This project examined the welfare of growing/finishing pigs on four treatments; a new alternative system called the Straw-Flow (c) (SF), which used roughly a 1/4 of the amount of straw of a traditional deep-straw bedded system (1.9 and 8 kg/d respectively), was compared to bare-concrete (BC), fully-slatted (FS) and deep-straw (DS) treatments using a multi-disciplinary study involving behaviour, physical health, productivity and physiology. The four pen treatments were all built within the same building and they all measured 4x2.7m. There were three replicates of entire male pigs which were randomly allocated to each treatment from approximately 28 to 89 kg. During daylight hours, the pigs on the straw-based treatments (ST), ie . the SF and the DS, spent approximately 26% of their time in straw-directed behaviour. Where there was no straw (NOST), ie , the BC and the FS, there was more inactivity (45% and 59% of time on the ST and NOST respectively, p< 0.001), behaviour directed towards the pen hardware (2% and 13% of time on the ST and NOST respectively, p&60 0.001), chewing penmates; (0.05% and 0.19% of time on the ST and NOST respectively, p< 0.07) and vacuum chewing (0.2% and 1.4% of time on the ST and NOST respectively, p< 0.001). These differences were thought to be due to a lack of suitable malleable substrate on the NOST treatments which caused a redirection in the exploratory and foraging behaviour of the pigs compared to the pigs from the ST treatments. However, there was more play on the ST compared to the NOST in the form of running and scampering (0.15% and 0.02% of time on the ST and NOST respectively, p< 0.05) and shoving and pushing penmates (2.9% and 1.8% of time on the ST and NOST respectively, p= 0.14).

Traoré, Fatoumata Diahara. ""Mother and I, we are Muslim women" : Islam and postcolonialism in Mariama Ndoye's Comme le bon pain and Ken Bugul's Cendres et braises." Thesis, McGill University, 2005. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=98589.

Full text
Abstract:
This thesis is a literary analysis of two novels, Comme le bon pain (2001) by Mariama Ndoye and Cendres et braises (1994) by Ken Bugul. It examines the representation of Islam in relation to African women's identity, with particular emphasis on its relationship with the postcolonial context of francophone West Africa. Chapter I reviews the emergence of African francophone literature by women authors and the trends of criticism that developed as a result of it. It also presents the theoretical framework of this research, namely feminist and postcolonial theories inspired by Frantz Fanon and African women theorists. Chapter II of this thesis explores the use of Sufi imagery in Cendres et braises and its metaphorical description of decolonization and of the postcolonial subject. Chapter III examines Comme le bon pain for Islamic elements and their interaction with African traditional beliefs, as it attempts to understand Ndoye's own attitude towards Islam. It briefly reviews definitions of syncretism and what was termed "African Islam." Chapter IV poses the question of whether the two novels can be inscribed within a feminist ideology, specifically in a postcolonial, West African and Muslim context.

Abstract:
This chapter assesses E.R. Dodds’s commentary on the Gorgias. Dodds’s edition of the Gorgias was the third commentary he published, and in some ways the most traditional. In his work on the Gorgias, he followed more closely a well-established channel of scholarship on a central author. Yet the book contains much that is characteristic of Dodds’s work, and in many passages one recognizes his distinctive voice. When Dodds was writing about the Gorgias, he had to deal with Plato as a critic of human politics and society, and he kept in view the author’s development into a reformer and a legislator who laid down the principles on which society must be based and the means by which morals and correct beliefs must be imposed upon mankind.

Full text
Abstract:
Peptides play key structural and functional roles in biochemistry, pharmacology, and neurobiology, and are important probes for research in enzymology, immunology, and molecular biology. The amino acid building blocks can be among the 20 genetically encoded L-residues, or else unusual ones, and the sequences can be linear, cyclic, or branched. It follows that rapid, efficient, and reliable methodology for the chemical synthesis of these molecules is of utmost interest. A number of synthetic peptides are significant commercial or pharmaceutical products, ranging from the sweet dipeptide L-Asp-L-Phe-OMe (aspartame) to clinically used hormones such as oxytocin, adrenocorticotropic hormone, calcitonin, and gonadotropin releasing hormone (GnRH) super-agonists. Synthesis can lead to potent and selective new drugs by judicious substitutions that change functional groups and/or conformations of the parent peptide. These include introduction of N- or C-alkyl substituents, unnatural or D-amino acids, side-chain modifications including sulfate or phosphate groups or carbohydrate moieties, and constraints such as disulfide bridges between half-cystines or side-chain lactams between Lys and Asp or Glu. Commercially important products that evolved from such studies include protease inhibitors, such as captopril and other angiotensin converting enzyme (ACE) inhibitors, peptidomimetic HIV protease inhibitors, and the somatostatin analog lanreotide. Most of the biologically or medicinally important peptides which are the targets for useful structure-function studies by chemical synthesis comprise under 50 amino acid residues, but occasionally a synthetic approach can lead to important conclusions about small proteins (full or domains) in the 100-200 residue size range. Methods for synthesizing peptides are divided conveniently into two categories: solution (classical) and solid-phase pep tide synthesis (SPPS). The classical methods have evolved since the beginning of the twentieth century, and they are described amply in several reviews and books (Wünsch, 1974; Finn and Hofmann, 1976; Bodanszky and Bodanszky, 1984; Goodman et al, 2001). The solid-phase alternative was conceived and elaborated by R. B. Merrifield beginning in 1959, and has also been covered comprehensively (Erickson and Merrifield, 1976; Birr, 1978; Barany and Merrifield, 1979; Stewart and Young, 1984; Merrifield, 1986; Barany et al., 1987, 1988; Kent, 1988; Atherton and Sheppard, 1989; Fields and Noble, 1990; Barany and Albericio, 1991; Fields et al., 1992; Gutte, 1995; Fields, 1997; Lloyd-Williams et al., 1997; Chan and White, 2000; Kates and Albericio, 2000).

Abstract:
At present, eight different libraries in Lithuania preserve 510 incunabula in their holdings. In the 15th century, Lithuania did not itself have printing houses, so books had to be imported. A majority of incunabula kept in Lithuania carry inscriptions which show that these books were brought to Lithuania as early as in the 16th or 17th century. However, extant book markings may also become a way of shedding light on historical events which influenced the fate of libraries, and, vice versa, a knowledge of historical events may fill in lacunae left by provenance marks in the history of a book.

Abstract:
The late 15th century became a time of dramatic changes in the Hebrew book-making as well. The Hebraica team of the 15cBOOKTRADE project prepared a thorough description of the extant copies of the Hebrew incunabula kept in the libraries of Europe and Israel. Notes of ownership, deeds of sale, personal remarks, institutional stamps, signatures of censors – all of them provide a rich picture of the distribution and use of Hebrew printed books throughout Europe (and also their ways from Europe to North Africa and the Middle East). Among a few hundreds of the checked volumes some were printed in Italy and remained there all the centuries since then, others were printed in Portugal and soon made their way to the Ottoman lands and from there to Yemen or Persia. Although the survey is not complete yet, since some important collections such as Biblioteca Apostolica Vaticana still need to be included in the MEI database, the main results can enrich our knowledge on certain rabbis and scholars or provide interesting evidence of communal life, literacy, trade, the role of women and of the books in private possession.

Abstract:
In the Marciana library the pressmark Classe XI, 45 (7439), as is well known, stands for Francesco de Madiis’s Zornale. What is less well known is that it actually refers to two manuscripts. Together with the Zornale, usually placed inside the front cover, is kept another, much smaller, manuscript list of books. The records of the library showed that the two documents arrived together in 1812, after their discovery in the attics of Palazzo Ducale. So far the second manuscript has not drawn the attention of scholars and no study on the Zornale has ever mentioned it; the relationship between the two is nevertheless worth clarifying. The manuscript, a quarto in agenda format, consists of sixteen leaves and the list is composed of 262 entries, among which there are 235 printed books. Its transcription and analysis allow the identification of the books and, in some cases, of the editions, revealing the presence of a significant number of books printed beyond the Alps, most of which are related to the Reformation, thus giving a clue to the identity of the owner, as well as a date, showing that the list could not have been written earlier than 1543.

Abstract:
Chapter 3 examines six manuscript books which influential hostess Sarah Sophia Child-Villiers, fifth Countess of Jersey (1785–1867) kept in 1805–24. It argues that these manuscript compilations are overlooked technologies of power, influence, and creativity in elite Regency social and literary networks. The books reflect the shift towards collecting original poems during album-keeping’s transition to a popular practice, and show Jersey’s developing consciousness of the album as an expression and extension of her own identity. The albums document the range of reading, copying, and composing practices associated with guests’ visits to the Jerseys’ house at Middleton Park, from parlour games and flirtation, more formal and public tributes, and prestigious personalized poems in autograph by celebrated poets including George Crabbe, Lord Byron, and Thomas Moore, as well as overlooked society poets such as W. R. Spencer.

Abstract:
The authors present a Student Response System for modern Internet-capable mobile devices, which was developed in a European R&D project, co-funded by the European Commission. The goal was to make a system that is designed for speed, ease of use, and flexibility for use in lectures. The authors have tried to make a time efficient and intuitive system that does not compromise flexibility and that enables the teacher to use any lecture format he/she sees fit. The only requirement is a computer with an Internet connection; the teacher is not bound to specific presentation software. The system is Web-based, enabling students to use their own mobile device or computer. The cost for both educational institutions and students is kept at a minimum, lowering the threshold for using the system in education. As of today, the program is free of charge and can be found at histproject.no.

Abstract:
In a remarkable example of chemoselective oxidation, Scott J. Miller at Yale University identified (Nature Chem. 2012, 4, 990) a peptide catalyst that selectively epoxidized the 6,7-olefin of farnesol 1. Phil S. Baran at Scripps-La Jolla developed (Nature Chem. 2012, 4, 629) the Tz°sulfonate as a “portable desaturase” capable of site-specific C–H functionalization of complex molecules, such as in the conversion of peptide 3 to 4. A unique method for the preparation of α-oxygenated ketones was developed (Angew. Chem. Int. Ed. 2012, 51, 7799) by Laura L. Anderson at the University of Illinois at Chicago. Cross-coupling of cyclohexenyl boronic acid with N-hydroxyphthalimide produced N-enoxyphthalimides 5, which underwent a trihetero [3,3]-sigmatropic rearrangement to produce, after hydrolysis and protection, ketone 6. The enantioselective α-hydroxylation of oxindole 7 with atmospheric O2 catalyzed by pentanidium 8 was reported (Org. Lett. 2012, 14, 4762) by Zhiyong Jiang at Henan University and Choon-Hong Tan at Nanyang Technological University. A catalytic Baeyer-Villiger oxidation of ketones such as 10 using highly reactive metal borate salts was developed (Angew. Chem. Int. Ed. 2012, 51, 9093) by Kazuaki Ishihara at Nagoya University. Masatoshi Shibuya and Yoshiharu Iwabuchi at Tohoku University found (Org. Lett. 2012, 14, 5010) that nitroxyl radicals such as 13 catalyzed the oxidative cleavage of diols to carboxylic acids, such as in the conversion of 12 to 14. A highly reactive iridium catalyst 16 was reported (Angew. Chem. Int. Ed. 2012, 51, 12790) by Ken-ichi Fujita and Ryohei Yamaguchi at Kyoto University, which had high turnover numbers under mild conditions for the oxidation of alcohols including 15. Frank W. Foss Jr. at the University of Texas at Arlington developed (Org. Lett. 2012, 14, 5150) a biomimetic Dakin oxidation of electron-rich aryl aldehydes such as 18, using the flavin-type catalyst 19, Hantzsch ester, and oxygen as the terminal oxidant. Flavin-catalyzed oxidation of aldehydes using catalyst 22 was also reported (Org. Lett. 2012, 14, 3656) by David R. Carbery at the University of Bath. Carlos F. Barbas III at Scripps-La Jolla developed (Angew. Chem. Int. Ed. 2012, 51, 12538) a catalytic conversion of aldehydes such as 24 to the corresponding O-acyl N-hydroxyimides (cf. 25), which could be used for in situ amidations and esterifications.

"R v Ball [1989] Crim LR 730 (CA) Facts: The defendant shot a neighbour. At his trial, the defendant’s defence was lack of intention to kill or cause harm: he thought he had loaded the gun with a blank cartridge. It appeared that he had previously attempted to fire two such blanks to scare and frighten the deceased from his land. For reasons which were not clear they had not detonated. He said that he kept live and blank cartridges together in the pocket of his overalls in the house. He had grabbed a handful when he had picked up the gun, intending only to frighten the deceased. Held, dismissing the appeal: R v Daweson (1985) 81 Cr App R 150 went no further than showing that the sober and reasonable man must look at the unlawful act to see if it was dangerous and not at peculiarities of the victim; in that case the victim had a heart condition. In cases of involuntary manslaughter, there was a distinction between unlawful and lawful acts resulting in death. Where the act was unlawful, the question for the jury was whether it was also dangerous in the sense that all sober and reasonable people would inevitably realise that it would subject the victim to the risk of some harm, albeit not serious harm. Questions of gross or criminal negligence were not material. In many cases the judge might have to give a direction on the question of a lawful act and gross or criminal negligence because the jury might not accept that an accused deliberately did an unlawful act. But in this case it was accepted on behalf of the appellant that he had unlawfully assaulted the deceased. His act in firing at the deceased was ‘an act directed at the victim’ (per Waller LJ in R v Dalby (1982) 74 Cr App R 348 at 352), with ‘no fresh intervening cause between the act and the death’ (per Lord Lane CJ in R v Goodfellow (1986) 83 Cr App R 23). He had used his own cartridges and loaded the gun himself; no other agency was involved. In manslaughter arising from an unlawful and dangerous act, the accused’s state of mind was relevant only to establish (a) that the act was committed intentionally; and (b) that it was an unlawful act (DPP v Newbury (1977) 62 Cr App R 291). Once (a) and (b) were established, the question of whether the act was dangerous was to be judged not by the appellant’s appreciation but by that of the sober reasonable man, and it was impossible to impute into his appreciation the mistaken belief that what he was doing was not dangerous because he thought he had a blank cartridge in the chamber. At that stage, his intention, foresight or knowledge was irrelevant. Does the dangerous criminal act have to be directed at the victim?" In Sourcebook Criminal Law, 773.

Abstract:
Accidentally, Josef Velenovský and František Mareš were both natives of South Bohemia and both carved their careers in science moving from physiology to philosophy as evident from conclusions drawn from their scientifi c research. Th us by the same token but each in his own way, they refl ected on man’s limited capacity for gaining knowledge and, by contrast, on the special signifi cance of technology which could not exist without thorough human understanding. On that account technology, which had made man’s work easier or helped him travel vast distances, at the same rate became a phenomenon that enabled man to force his will upon his surroundings. Th e inevitable eff ect of such conduct was the confl ict between man -created technology and man’s existential dependence on Nature. In view of the fact that the two scientists published their observations about the eventuality of technology being turned against man no later than the turn of the twentieth century, the topicality of their ken is even more surprising.

Abstract:
Neolepenism is a new type of energy efficient architecture that could respond to the challenges of sustainable development, primarily as a passive means of protection in the fight against the effects of global warming and climate change. The author improved and optimized the positive experiences of the architecture of Lepenski Vir (Serbia) and made a model of a small family house of neolepenism with a flat roof, which he presented at the 50th International Congress and Exhibition on HVAC in Belgrade in 2019. During the presentation of the model, in the discussion at the exhibition, the question was asked: "Can this architecture be applied in climatic conditions with frequent occurrence of morning fog?" Using the meteorological databases of the Meteonorm program and the typical meteorological years for Ljubljana (Slovenia), as well as the previously developed program in Excel that was used in calculations for this architecture of neolepenism, the author presents the results for Ljubljana, a city located in the valley and where morning fogs are common. In meteorological data, the appearance of frequent morning fog is manifested through a reduced intensity of direct solar radiation in the morning. The paper presents conclusions concerning the optimal orientation of neolepenism buildings for this type of climate depending on the energy class of the building.The obtained results at the level of the whole year indicate that for the needs of heating, the eastern orientation is slightly better than the southern one for the buildings of energy class B, while for the less isolated buildings, the southern orientation has a slight advantage. For the area of ​​Ljubljana, the orientation of the neolepenism building does not play a significant role for heating needs, but still the author believes that the originally assumed eastern orientation should be kept as optimal, due to the need for cooling during the summer season. However, in addition to good thermal insulation, the compactness of the form of neolepenism architecture also plays a crucial role in saving energy and achieving thermal comfort.

Abstract:
In order to investigate the ultimate strength of structures and components under an unexpected huge earthquake, it is necessary to understand the final fracture condition under static and cyclic loadings. This study compared the crack growth behavior under monotonic and cyclic loading conditions for carbon steel SGV410 used for pressure vessels in nuclear power plants. Fatigue tests were carried out for CT specimens 50 mm wide (1CT), 75 mm wide (1.5CT) and 100 mm wide (2CT) using three kinds of test methods, namely monotonic loading (ML), load line displacement amplitude increasing (V-inc.) and fatigue crack growth (FCG) tests. For the FCG tests, the maximum load was kept constant under cyclic loading with full unloading (R = 0), fully reversed loading (R = −1) and fully reversing the load line displacement (R = −1.5) and the crack growth characteristics were evaluated by the fracture mechanics approach.

Full text
Abstract:
A series of stress-controlled bi-directional cyclic shear tests under isotropic consolidation conditions were conducted for simulating the cyclic stress induced by wave loading. The area bounded by the elliptical stress path was kept unchanged, while the ratio (R) of the axial cyclic shear stress and the torsional cyclic shear stress was changed in order to research the effect of varied two cyclic stress components on the pore water pressure, strength and deformation behaviors of saturated soft clay. The test results show that with a decrease in R, the residual pore water pressure decreases at first and then increases, and it reaches the lowest at R=1 at the same cycle number, while the amplitude of fluctuated pore water pressure decreases all along. The relationship curves between normalized ratio of pore water pressure and ratio of cycle number have significant differences with different R. The cycle number at failure increases at first and then decreases with decreasing R. It reaches the maximum at R=1, indicating that the dynamic strength is the highest when the stress path is close to a circle. The dynamic stress-strain relationship curves with different R indicate that both the axial and the torsional strains caused by the bi-directional cyclic loadings are mainly the cyclic strains, at the same time, the residual strains appear. With decreasing R, the amplitude of axial cyclic strain decreases and the ratio of axial residual strain and cyclic strain increases firstly and then decreases, while the amplitude of torsional cyclic strain increases. The cyclic shear strain is basically symmetric at R=1, while the residual shear strains appear under other conditions.

Full text
Abstract:
Flame interaction between two neighboring burners in a gas turbine combustor is investigated numerically for pursuit of its effect on NOx emission from the burners. In a model chamber or liner, EV burners with double cone are installed. Two burners with the opposite rotating directions (L-R type burner) of air stream are adopted and the distance between them is variable from 74.2 mm to 222.6 mm by the step size of 37.1 mm and an additional distance of 171.3 mm is considered. Gaseous methane and air are adopted as fuel and oxidizer, respectively. From steady-state numerical analyses, flow, temperature, and NO concentration fields are calculated in all computational cases to find their correlation with NO formation. NO emission is evaluated at the exit of the model chamber with two burners as a function of burner distance. Swirl flows induced by EV burner are kept up to the liner exit, but with weaker swirl than that of the same rotating burners (L-L type burners). The case of shortest distance presents strong correlation between two flames while the other cases present weak correlation. In all cases of L-R type burners, NO emission is lower than that of L-L type burners, which results from change in swirl flow patterns. NO emission from L-R type burners with intermediate distances is greater than that from a single burner, but it is smaller than the latter with relatively shorter and longer burner distances.

Full text
Abstract:
The Flame Transfer Function (FTF) of premixed laminar conical flames submitted to flowrate modulations is a configuration of fundamental and practical interest for improving the design of thermo-acoustically stable low power burners. Many theoretical models were developed for relatively large single flames based on labscale experiments, while most domestic and industrial burners operate with a collection of small injectors. Measurements of the FTF of laminar premixed methane/air conical flames are compared with analytical expressions deduced from kinematic descriptions of flame wrinkling when the burner size is reduced. The flame aspect ratio is kept constant corresponding to a flame tip half-angle α = 14.47° and the radius of the injector is reduced from R = 11 mm to R = 1.5 mm. Three different velocity perturbation models are tested, with and without an additional model accounting for the dynamics of the flame anchoring point. For the largest flames R = 11 mm and 7 mm, the best agreement is found for a FTF model with an incompressible velocity disturbance in the fresh reactants stream. The anchoring point dynamics has only a weak influence on the FTF gain and phase-lag plots of these flames. For the smallest flames (R = 1.5 mm), a FTF model based on a uniform flow perturbation yields the best match with experiments for the phase-lag plot, but none of the three velocity perturbation models reproduce the FTF gain evolution as measured in experiments. Including the contribution of the anchoring point dynamics to the FTF significantly changes the FTF gain predictions, but it does not allow to reproduce the main features observed in the measured gain curves and the phase-lag predictions worsen. It is concluded that an additional modeling effort is needed to adequatedly reproduce the FTF of small premixed laminar conical flames.

Full text
Abstract:
An experimental study of wall heat transfer and friction characteristics of a fully-developed turbulent air flow in a rectangular channel with transverse ribs on one, two, and four walls is reported. Tests were performed for Reynolds numbers ranging from 10,000 to 80,000. The pitch-to-rib height ratio, P/e, was kept at 8 and rib height-to-channel hydraulic diameter ratio, e/Dh, was kept at 0.0625. The channel length-to-hydraulic diameter ratio, L/Dh, was 15. The heat transfer coefficient and friction factor values were enhanced with the increase in the number of ribbed walls. The friction roughness function, R(e+), was almost constant over the entire range of tests performed and was within comparable limits of the previously published data. The heat transfer roughness function, G(e+), decreased with additional ribbed walls and compared well with previous work in this area. Friction data obtained experimentally for the case with four ribbed walls compared well with the values predicted by the assumed theoretical relationship used in the present study and past publications. Results of this investigation could be used in various applications of internal channel turbulent flows involving different number of roughened walls.

Abstract:
The advances of micro-fabrication techniques allow for the manufacturing of micro heat exchangers or micro reactors. These micro devices are characterized by a large surface-to-volume ratio and, hence, allow for the transfer of large heat fluxes or offer large catalytic surfaces for reactions. The design and optimization of such micro devices heavily relies on correlations for pressure drop and heat transfer, as well as on information on the laminar/turbulent transition. As these questions are still discussed controversially in literature, a careful investigation appears highly desirable. We concentrate onto rectangular stainless steel micro channels with a hydraulic diameter of dh ≅ 133 μm. Three aspect ratios are engaged, namely 1:1, 1:2, 1:5, whereas the hydraulic diameter is kept constant. The average roughness depth of the channel walls is r ≅ 1–2 μm in general, specific channels are of roughness r ≅ 25 μm. Filtered and degassed deionized water is driven at pressure differences up to 20 bar through the channels, allowing for Reynolds numbers up to Re = 4000. The measuring techniques allow for a highly-accurate determination (i) of the mass flow rate (precision weighting), (ii) of the temperatures at inlet and outlet, (iii) of the pressure drop, and (iv) of the time-resolved velocity field (μPIV). We find from all measured quantities — consistently — the laminar/turbulent transition for smooth channels in the range Rec = 1900–2200, in agreement with findings for macroscopic channels. The influence of rough channel walls appears particularly strong for the micro channels of aspect ratio 1:5 (Rec = 1000). This raises the question, whether the dimensionless group (r/dh) remains the relevant parameter at extreme aspect ratios. In this article we focus on the μPIV results.

Full text
Abstract:
The aim of this paper is to have a view of different levels of model simplifications for a simple hydraulic circuit. The bond graph is used to synthesize the simplifications and the different assumptions behind. Different models were built in order to keep continuity in model simplification. These models have the two causalities allowed for a particular physical phenomenon. It is believed that software will give access to different levels of model simplifications and the user will choose between these different levels the proper one that will answer to his question. However this proper model will only be achieved step by step using continuity in model simplification. The paper also shows that systems may include very different levels of power (pilot and main stages or thermal effects) and in such a case at least one C-, I- or R-element should be kept per power level.

African Open Science Platform Part 1: Landscape Study. Academy of Science of South Africa (ASSAf), 2019. http://dx.doi.org/10.17159/assaf.2019/0047.

Full text
Abstract:
This report maps the African landscape of Open Science – with a focus on Open Data as a sub-set of Open Science. Data to inform the landscape study were collected through a variety of methods, including surveys, desk research, engagement with a community of practice, networking with stakeholders, participation in conferences, case study presentations, and workshops hosted. Although the majority of African countries (35 of 54) demonstrates commitment to science through its investment in research and development (R&D), academies of science, ministries of science and technology, policies, recognition of research, and participation in the Science Granting Councils Initiative (SGCI), the following countries demonstrate the highest commitment and political willingness to invest in science: Botswana, Ethiopia, Kenya, Senegal, South Africa, Tanzania, and Uganda. In addition to existing policies in Science, Technology and Innovation (STI), the following countries have made progress towards Open Data policies: Botswana, Kenya, Madagascar, Mauritius, South Africa and Uganda. Only two African countries (Kenya and South Africa) at this stage contribute 0.8% of its GDP (Gross Domestic Product) to R&D (Research and Development), which is the closest to the AU’s (African Union’s) suggested 1%. Countries such as Lesotho and Madagascar ranked as 0%, while the R&D expenditure for 24 African countries is unknown. In addition to this, science globally has become fully dependent on stable ICT (Information and Communication Technologies) infrastructure, which includes connectivity/bandwidth, high performance computing facilities and data services. This is especially applicable since countries globally are finding themselves in the midst of the 4th Industrial Revolution (4IR), which is not only “about” data, but which “is” data. According to an article1 by Alan Marcus (2015) (Senior Director, Head of Information Technology and Telecommunications Industries, World Economic Forum), “At its core, data represents a post-industrial opportunity. Its uses have unprecedented complexity, velocity and global reach. As digital communications become ubiquitous, data will rule in a world where nearly everyone and everything is connected in real time. That will require a highly reliable, secure and available infrastructure at its core, and innovation at the edge.” Every industry is affected as part of this revolution – also science. An important component of the digital transformation is “trust” – people must be able to trust that governments and all other industries (including the science sector), adequately handle and protect their data. This requires accountability on a global level, and digital industries must embrace the change and go for a higher standard of protection. “This will reassure consumers and citizens, benefitting the whole digital economy”, says Marcus. A stable and secure information and communication technologies (ICT) infrastructure – currently provided by the National Research and Education Networks (NRENs) – is key to advance collaboration in science. The AfricaConnect2 project (AfricaConnect (2012–2014) and AfricaConnect2 (2016–2018)) through establishing connectivity between National Research and Education Networks (NRENs), is planning to roll out AfricaConnect3 by the end of 2019. The concern however is that selected African governments (with the exception of a few countries such as South Africa, Mozambique, Ethiopia and others) have low awareness of the impact the Internet has today on all societal levels, how much ICT (and the 4th Industrial Revolution) have affected research, and the added value an NREN can bring to higher education and research in addressing the respective needs, which is far more complex than simply providing connectivity. Apart from more commitment and investment in R&D, African governments – to become and remain part of the 4th Industrial Revolution – have no option other than to acknowledge and commit to the role NRENs play in advancing science towards addressing the SDG (Sustainable Development Goals). For successful collaboration and direction, it is fundamental that policies within one country are aligned with one another. Alignment on continental level is crucial for the future Pan-African African Open Science Platform to be successful. Both the HIPSSA ((Harmonization of ICT Policies in Sub-Saharan Africa)3 project and WATRA (the West Africa Telecommunications Regulators Assembly)4, have made progress towards the regulation of the telecom sector, and in particular of bottlenecks which curb the development of competition among ISPs. A study under HIPSSA identified potential bottlenecks in access at an affordable price to the international capacity of submarine cables and suggested means and tools used by regulators to remedy them. Work on the recommended measures and making them operational continues in collaboration with WATRA. In addition to sufficient bandwidth and connectivity, high-performance computing facilities and services in support of data sharing are also required. The South African National Integrated Cyberinfrastructure System5 (NICIS) has made great progress in planning and setting up a cyberinfrastructure ecosystem in support of collaborative science and data sharing. The regional Southern African Development Community6 (SADC) Cyber-infrastructure Framework provides a valuable roadmap towards high-speed Internet, developing human capacity and skills in ICT technologies, high- performance computing and more. The following countries have been identified as having high-performance computing facilities, some as a result of the Square Kilometre Array7 (SKA) partnership: Botswana, Ghana, Kenya, Madagascar, Mozambique, Mauritius, Namibia, South Africa, Tunisia, and Zambia. More and more NRENs – especially the Level 6 NRENs 8 (Algeria, Egypt, Kenya, South Africa, and recently Zambia) – are exploring offering additional services; also in support of data sharing and transfer. The following NRENs already allow for running data-intensive applications and sharing of high-end computing assets, bio-modelling and computation on high-performance/ supercomputers: KENET (Kenya), TENET (South Africa), RENU (Uganda), ZAMREN (Zambia), EUN (Egypt) and ARN (Algeria). Fifteen higher education training institutions from eight African countries (Botswana, Benin, Kenya, Nigeria, Rwanda, South Africa, Sudan, and Tanzania) have been identified as offering formal courses on data science. In addition to formal degrees, a number of international short courses have been developed and free international online courses are also available as an option to build capacity and integrate as part of curricula. The small number of higher education or research intensive institutions offering data science is however insufficient, and there is a desperate need for more training in data science. The CODATA-RDA Schools of Research Data Science aim at addressing the continental need for foundational data skills across all disciplines, along with training conducted by The Carpentries 9 programme (specifically Data Carpentry 10 ). Thus far, CODATA-RDA schools in collaboration with AOSP, integrating content from Data Carpentry, were presented in Rwanda (in 2018), and during17-29 June 2019, in Ethiopia. Awareness regarding Open Science (including Open Data) is evident through the 12 Open Science-related Open Access/Open Data/Open Science declarations and agreements endorsed or signed by African governments; 200 Open Access journals from Africa registered on the Directory of Open Access Journals (DOAJ); 174 Open Access institutional research repositories registered on openDOAR (Directory of Open Access Repositories); 33 Open Access/Open Science policies registered on ROARMAP (Registry of Open Access Repository Mandates and Policies); 24 data repositories registered with the Registry of Data Repositories (re3data.org) (although the pilot project identified 66 research data repositories); and one data repository assigned the CoreTrustSeal. Although this is a start, far more needs to be done to align African data curation and research practices with global standards. Funding to conduct research remains a challenge. African researchers mostly fund their own research, and there are little incentives for them to make their research and accompanying data sets openly accessible. Funding and peer recognition, along with an enabling research environment conducive for research, are regarded as major incentives. The landscape report concludes with a number of concerns towards sharing research data openly, as well as challenges in terms of Open Data policy, ICT infrastructure supportive of data sharing, capacity building, lack of skills, and the need for incentives. Although great progress has been made in terms of Open Science and Open Data practices, more awareness needs to be created and further advocacy efforts are required for buy-in from African governments. A federated African Open Science Platform (AOSP) will not only encourage more collaboration among researchers in addressing the SDGs, but it will also benefit the many stakeholders identified as part of the pilot phase. The time is now, for governments in Africa, to acknowledge the important role of science in general, but specifically Open Science and Open Data, through developing and aligning the relevant policies, investing in an ICT infrastructure conducive for data sharing through committing funding to making NRENs financially sustainable, incentivising open research practices by scientists, and creating opportunities for more scientists and stakeholders across all disciplines to be trained in data management.
