description: Nano-sized Al (nAl) features high reactivity that, while desirable for effective energy conversion during the combustion, yields possible issues related to its storage. This paper investigates the ageing behavior of nAl under different relative humidity conditions (RH, from 80% to 10%) at the temperature of 333 K. Fresh and aged powders are characterized by electron microscopy, x-ray diffraction, and thermal analysis. The marked sensitivity of nAl (40 nm) to ageing is testified by a nearly full metal content (CAl) loss in just 24 hours (RH = 80%). Under the same condition, conventional 30 m-counterpart looses 13% of the original CAl in 14 days.

description: Imposing a propulsor behind a body can make use of its disturbed flow by decreasing the velocity of air entering the propulsor to save energy and increase the propulsive efficiency since a propulsor consumes less power if the incoming velocity is less. In this article, investigation is conducted on a propeller placed aft an airfoil where it is placed in the boundary layer of the airfoil. This research is conducted to stand on the benefits and drawbacks of this configuration and investigate the mutual interaction between the propeller and airfoil. This interaction is measured by the impact on the power consumption and efficiency, airfoil characteristics, and boundary layer properties.

Synthesis of 15-aza-salicylihalamide A analogues
Creators: name: Balan, Dan
Publisher: name: RMIT University
Year: 2024

description: Salicylihalamide A, a potent cytotoxic natural product, was isolated by Boyd and co-workers in 1997 from a marine sponge Haliclona sp. collected from waters around Rottnest Island which is situated 18 km off the coast of southern Western Australia. This compound is characterized by a unique structure as well as by different biological activities with interesting mechanisms of action, displaying cytotoxicity at nanomolar levels against several human tumor cell lines. The majority of SAR studies have been conducted on salicylihalamide derivatives with modified enamide side chains as well as on the 12-membered ring and it has been shown that some small modification of the enamide moiety or of the macrolactone ring are tolerated without substantial loss of cytotoxic activity. For example, the semisynthetic 15-aza-epothilone B was found to exhibit a better therapeutic range than epothilone B because of the stability of the macrolactam. This led us to our hypothesis that the modification of the 12-membered macrolactone in salicylihalamide A to a macrolactam would provide a more stable macrocyclic system and thus would be an interesting target for synthesis and biological evaluation. A key step in the synthesis of the new lactam analogue of salicylihalamide A was a photochemical acylation reaction. In order to prepare the desired E-lactam we have investigated the formation of the macrocyle using a RCM procedure. Conversion of macrolactam into the vinyl iodide followed by Cu catalysed cross coupling with the 2,4-(Z,Z)-heptadienoic amide gave the 15-aza-salicylihalamide A analogue in good yield. Due to its promising bioactivity profile, the first total synthesis of the novel salicylihalamide A lactam analogue was accomplished in 17 linear steps from 2,6-dihydroxybenzoic acid with an overall yield of 0.70%. The new analogue was tested for cell growth inhibition against several leukemia cell lines. The results showed that the 15-aza-salicylihalamide A analogue exhibited antiproliferative effects at sub-micromolar concentrations.

description: This study introduces a new concept in active microfluidics as it employs surface acoustic waves (SAW) to induce active microfluidic mixing in a microanalytical flow system. A SAW driven microfluidic platform integrated with a flow injection analysis (FIA) system is presented. The platform is equipped with a micromixer and a sensitive photodetector for the rapid on-line quantification of chemiluminescent species. The microfabricated mixer consists of a 100 µL chamber cast in polydimethylsiloxane (PDMS) with an embedded single interdigitated SAW transducer. The reagent and sample are injected into the chamber and actively mixed using unidirectional SAW streaming. Several experimental configurations were optimised by varying the power and duration of the SAW input, fluid flow rate and the orientation of the micromixer inlets relative to the SAW aperture. The mixing efficiency of the SAW Micromixer was quantified as a function of the spatial shifting of a fluorescent tracer in the SAW Micromixer and later as a function of the chemiluminescent output of a chemiluminescent reaction under different conditions using image analysis. The effect of SAW on the microanalytical sensitivity was assessed using the chemiluminescent species tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate. The microanalytical sensitivity was increased by two orders of magnitude with the use of SAW active mixing in comparison with conventional FIA systems, resulting in a theoretical detection limit of approximately 0.02 µgL-1 for the chemiluminogenic test substance L-proline. Application to selected chemiluminogenic pesticides resulted in double the sensitivity of conventional FIA systems, with a theoretical detection limit of approximately 0.96 µgL-1 for the pesticide glyphosate using tris(2,2′-bipyridyl)dichlororuthenium(II) hexahydrate as the chemiluminescent reagent.

description: The combustion behaviour of paraffin-based hybrid rocket fuels in combination with gaseous oxygen (GOX) was investigated in the framework of this research. Tests were performed in a 2D slab burner configuration with windows on two sides at atmospheric conditions. High speed videos were recorded and analysed in detail by using an automated video evaluation routine. Two different decomposition techniques were applied to the scalar field of the flame luminosity. The results show that the combustion is dominated by wave-like structures and that the most excited frequencies and wavelengths characterizing the liquid melt layer depend on the fuel viscosity and geometry.

description: The objective of this paper is to show how to build a nonlinear robust control law, which ensures trajectory tracking for a drone quadrotor under unpredictable wind perturbations. The first step is to find the aerodynamic forces and moments using a combination of momentum and blade element theory. Then the model is rewritten in state-space form, where the control inputs are selected to be proportional to the squares of rotor angular velocities. The other terms dependent linearly on rotors and wind velocities are considered as disturbances. Such a decomposition of thrust and selection of disturbances are almost exact in the hover flight. In literature, fixed bounds are often assumed on each component of the disturbance input vector, but for synthesis of the proposed control law, the big issue is that the disturbance depends on wind signals, the control itself, and state of the system. Chattering effects and their reduction are analysed and investigated in the last part of the paper by introducing rotors dynamics in control design. High order sliding mode control is applied and the recent tool of quasi-continuous sliding mode control is analyzed. Results of numeric experiments demonstrate the effectiveness of the proposed controls.

title: Meinungsmanipulation in Erik Regers neusachlichen Zeitromanen "Union der festen Hand" (1931) und "Das wachsame Hähnchen" (1932)
Creators: name: Wendt, Marion
Year: 2010

description: Die vorliegende Arbeit befasst sich mit der Darstellung der Meinungsmanipulation durch Pressepolitik und Propagandatätigkeit in Erik Regers neusachlichen Zeitromanen „Union der festen Hand“ (1931) und „Das wachsame Hähnchen“ (1932). Da Erik Reger und seine Romane einem breiteren Lesepublikum nicht bekannt sind, war es erforderlich, zunächst einen kurzen Abriss über die Neue Sachlichkeit und die zentralen Charakteristiken des damals sehr populären Zeitromans zu geben, um anschließend zeigen zu können, weshalb Erik Reger dieser Strömung zugeordnet werden kann. Dabei wurde auch auf seine journalistischen Tätigkeiten hingewiesen, da Erik Reger die Annäherung des Romans an das journalistische Medium der Reportage propagierte, und sich als Autor, Beobachter und Vivisekteur seiner Zeit sah. Nach diesem Einleitungskapitel wurden zum näheren Verständnis der Romane der formale und inhaltliche Aufbau besprochen. Hier sollten die Gemeinsamkeiten und Unterschiede zwischen den Romanen herausgearbeitet werden und auch gezeigt werden, inwieweit Reger die Forderungen der Neuen Sachlichkeit nach einer objektiven Schilderung der Wirklichkeit, die eine Analyse der Gesellschaft liefern soll, umsetzte. Hierbei muss gesagt werden, dass trotz des neutralen Er-Erzählers, der als unbeteiligter Beobachter der Ereignisse gelten kann, Mittel der Leserlenkung verwendet werden, die das Geschilderte werten. Daran anschließend folgt die Analyse der beiden Romane in Bezug auf die Propagandatätigkeit der Vereine. Eingegangen wird dabei auf die Verstrickungen der Vereine mit der Politik, die es ihnen ermöglicht, die Machthabenden zu ihren Gunsten zu manipulieren. Welche Strategien die Vereine einsetzen, um ihre Ziele zu erreichen, ist dabei die Hauptfrage der Untersuchung. Dabei werden Gemeinsamkeiten und Unterschiedlichkeiten in der Zielsetzung, die Union verfolgt die Ausschaltung der Gewerkschaften, das Bürgertum möchte seine führende Stellung innerhalb der Gesellschaft zurückerobern, und den daraus entstehenden Konsequenzen herausgearbeitet. Weiters wird versucht, die Gründe für die erfolgreiche Beeinflussung der Arbeiter bzw. des Bürgertums aufzuzeigen. Dies erfolgt durch die Konzentration auf jeweils eine von den Vereinen propagierte Phrase, wie die „schicksalsverbundene Werksgemeinschaft“ in „Union der festen Hand“ und Gustav Roloffs Idee des Ethischen in „Das wachsame Hähnchen. Abschließend wird in einem eigenen Kapitel auf die intransparente Pressepolitik der Vereine eingegangen. Hierbei soll gezeigt werden, welche Umstände dazu führen, dass die Vereine die Meinungsmanipulation erfolgreich umsetzen können, und weshalb sich kein schlagkräftiger Gegenpol entwickeln kann.

description: This paper presents the first results of monopropellant decomposition tests obtained from monolithic ceramic catalysts produced by means of additive layer manufacturing techniques and using ceramic precursors. The purpose is to compare the performance of printed monoliths with traditionally manufactured catalysts with respect to decomposition of highly concentrated hydrogen peroxide. Small holes with a pitch larger than 0 are generally difficult to manufacture. Holes with a diameter of 1.25 mm are difficult to manufacture when the pitch is larger than 2. Decomposition tests revealed that the manufacturing process does not influence the transient pressure performance but is noticeable in the transient temperature performance. However, the influence is only present during part of the transient phase. For optimum transient performance the surface area-to-volume ratio should be maximised.

description: Underground pipes are essential infrastructure for the transport of water, oil and gas. The presence of localised pitting corrosion has been identified as one of the main deterioration mechanisms for metal pipes. When exposed to external loadings, these corroded pipes can easily fail due to intensified stresses at the corrosion pit. Disruptions to pipelines not only greatly affect the life of citizens, but also cause severe economic loss and pose safety risk. Therefore, accurate prediction of safe design life of buried pipes is significant. The main objective of this research is to investigate the effect of corrosion on the mechanical properties of cast iron pipes. A relatively long-term corrosion test was conducted on cast iron pipe in a corrosive clay soil. The corrosion behaviour of pipes was thoroughly examined using various corrosion techniques. At designated points of time, fracture toughness tests were conducted on single-edge bend specimens that were cut from the pipe wall. The results showed effective outcomes for corrosion behaviour in buried pipes and mechanical properties deterioration. A new three-dimensional geometrical model for sharp corrosion pits is proposed. The domain integral method has been employed, in conjunction with a three-dimensional finite element analysis, to derive the stress intensity factors for pipes. An expression of the maximum stress intensity factors has been developed for corroded pipes and the upcrossing method is employed to quantify the probability of fracture failure. This thesis concludes that both the mechanical properties and microstructure of material are changed due to corrosion. The proposed stochastic model of stress intensity factor can serve as a useful tool to predict the failure of buried cast iron pipes with improved accuracy. This research work will enhance the current knowledge of corrosion and mechanical property degradation of metal pipes and improve estimations of the remaining safe life of buried pipelines.

description: The purpose of this study is to present an inverse heat transfer method which was developed and applied for the calculation of the heat flux and temperature profiles in an experimental multi-element rocket engine operated with GOX/GCH4 . The algorithm is based on an iterative optimization using a conjugate gradient method and utilizes the thermocouple measurements embedded in the material of the capacitively cooled combustor to provide an estimate for the hot gas heat flux. The method had been applied for the calculation of single-element engines by the authors and has now been extended to include the more complex geometry of a combustor consisting of five injectors. The analysis presented in this work is based on experimental data obtained with the heat-sink rectangular engine at a pressure of 20 bar and various mixture ratios ranging from 2.6 to 3.4. The resulting temperature fields of the inverse method demonstrate a good agreement with the measurements and the injector footprint as well as transient effects during start-up are successfully captured. The key features of the heat flux results are further discussed in the paper.

description: The design rules dealing with reusable Liquid Rocket Engines are similar as expendable engine, but in fact they are not. The reusable engines are to be designed for numerous missions with many start up, shutdown and long life. Liquid Rocket Engine Reusability leads to improve design rules: low stressed components meaning, low tip Speed for rotating parts and a temperature as low as possible for hot parts like Combustion Chamber. These considerations promote cold bleed engine burning Lox/Methane propellants. Indeed, Bleed rocket engine don\'t use gas generator and the Lox/Methane combination compared to LOX/LH2 according its high bulk density reduces drastically the Launch Vehicle Tanks Sizes. More compared to Lox/Kerosene the low soot emission and good CH4 thrust cooling capacity without risk of cracking and deposit are in favour of Lox/Methane. A preliminary design a 250 kN (56 klbf) Bleed Rocket to thrust a Nano Launch Vehicle (NLV) is the topic of this paper. In complement a 1000 kN (224klbf) four engines (4*250 kN) cluster bay design and a comparison expendable versus reusable design are addressed. This cluster bay is to thrust a medium launch vehicle.

description: The formation of aluminum agglomerates during combustion of aluminized solid propellants is known to have a significant impact on the behavior of the motor. In this paper, we propose a phenomenological agglomeration model whose input data is obtained from a mesoscale solid propellant simulation code. This new coupling strategy is very promising since it has the potential to model various physical effects on agglomeration. First applications of the model on a typical industrial propellant show encouraging agglomerate size distributions consistent with classical experimental data.

description: Combustion experimental test at subscale is a key element for the knowledge improvement of the design of liquid rocket engine. Within the frame of a CNES ONERA common research program, the MASCOTTE test bench has been used to gather an important experimental database of H2/O2 fire tests. In order to progress in the characterization of the test set up, a campaign was performed dedicated to the determination of the combustion chamber wall temperature dispersions for different gas/gas operating points. The identification of the heat fluxes on the injector face plate requires an improvement of post processing methods. A new methodology was then developed and validated by ONERA in order to solve the inverse heat conduction problem for complex 3D geometry with embedded local measurements.

description: The effect of blowing/suction through perforated surfaces on the turbulent boundary layer was studied experimentally at Mach number M = 1.4. In the experiments, several different porous surfaces were investigated in a wide range of the blowing/suction mass flow rate. The distributions of the integral parameters of boundary layer were obtained depending on the type of porosity and mass flow rate. Data analysis has showed a significant influence of shock waves generated near the holes on the turbulent boundary layer. The integral effect from shock waves on boundary layer depends on set of parameters, which makes search of optimal parameters of porosity difficult.

description: This study explores the way in which Primary School Principals perceive and experience emotions in their day-to-day lives. To understand the varying elements of school leadership a qualitative research approach using semi-structured interviews was used, which was appropriate due to the social and psychological nature of the topic being studied. Two interviews were conducted a year apart with participants to provide a detailed examination of the participants’ experiences and to gain deeper insights into their perceptions of emotions in their work.

Studies from both qualitative and relevant quantitative literature informed the analysis. In Chapter 4, coding was done by reading through the data and categorising information using predetermined (a priori) codes. Categories selected for initial analysis were instructional leadership, transformational leadership, perceptiveness, empathy, self-awareness, self-regulation, self-regard, loneliness, role conflict, work stress, pressure, competing demands, loneliness, mentoring and collegiate groups.

Chapter 5 presents a summation of four main themes that emerged from the data analysis of the two sets of interviews. After using an Interpretative Phenomenological Analysis (IPA) approach to transcribe, code and examine the interviews for careful clarification and analysis the four main themes to emerge from this study were Pressure, Relationships with Others, Relationship with Self and Support and Mentoring.

The Principals viewed emotional intelligence as an ability to recognise and appropriately respond to the emotions of themselves, their students, teachers, parents and other members within their learning community. They believed that relationships were a fundamental part of their role and that an effective leader needed strong interpersonal skills. Daily internal and external pressures were a common experience for them, impacting on their emotional wellbeing. Their relationships with themselves included considerations of self-awareness, self-regulation, self-regard, and loneliness. Participants placed great significance on their relationships with others, citing empathy, perceptiveness, self-awareness and self-regulation as important. Regarding their own need for support, they showed a preference for small local peer-to-peer collegiate groups. Principals who reported a low self-regard were unlikely to create, or participate in, collegiate groups, and so dealt with the issues in their schools in isolation. The thesis concludes with some recommendations for practice.

description: In the framework of ESA FLPP, Nammo is working on the development of the Unitary Motor (UM), a 30 kN hybrid rocket motor based on 87.5% H2O2 - HTPB, and the Nucleus, a sounding rocket propelled by UM and to be launched from Andoya Space Center to reach over 100 km altitude. The Nucleus is conceived as a demonstrator of the hybrid technology and its possibility of being upscaled whilst maintaining competitive performance. UM went through two development phases, successfully concluded in early 2017 with great propulsive performance demonstrated. The development of the Nucleus is ongoing and static test campaign is planned to be completed during fall 2017. This article provides the status of Nammo\'s activities on its large scale hybrid in order to get ready for Space.
Targeted sampling effect, on the percentage of positive responses in a forensic laboratory, in three one-year, periods of ten years
Creators: name: Dorri, Ameneh

description: Abstract: The forensic toxicological analysis involves a variety of samples for drug detection and with technological advancements, the need for targeted sampling increases. Various samples are analyzed after the sample preparation, often by gas chromatography-mass spectrometry (GC-MS). Depending on the drugs (pharmacodynamics and kinetics), there are general scientific predictions about the distribution of drugs in the body [1], but in practice, what will be the positive results in the same extraction method?  The objective of this article was to provide another level of biological matrix classification that can affect results in the same sample preparation techniques. This study was performed on about three thousand postmortems of the toxicology laboratory of forensic medicine (Guilan), in three one-year periods (1390, 1396, and 1400), during a decade. Urine, liver, stomach, blood, and bile after liquid-liquid extraction were examined by GC-MS in a general method (HP_5 MS column with initial, final, inlet, and interface temperatures and the rate of temperature, were respectively, 60 ºC, 280ºC, 250 ºC, 280, ºC and 20 ºC min1). The positive responses were determined in each group of samples by studying for drugs, toxins, and their metabolites in the list of about 650 organic compounds (such as medicines, drugs, toxins, etc.) which were already registered in the local software library with a determined retention time and a high match quality (more than 75%). Positive and negative results were recorded and compared by sample type. The results by years were determined and the statistical percentage of positive (desired) results, were as follows; urine, bile, stomach content, liver, and blood in 1390, were respectively 0, 36, 5,54,88, 1n 1390, 11, 25, 50,72, 1n 1396 and 10, 15, 44,49 77 1n 1400 (a total average can be seen in the pie chart, with 36% urine, 26% bile, 21% stomach content, 12% liver, and blood, 5%). In all three research periods, the results showed that the positive answers were related to the following samples: urine, stomach contents, and bile, which were referred to as the "golden triangle of diagnosis”. Each sample has its characteristics, but in the case of some others, this characteristic is more obvious e.g., in urine samples, drugs can be concentrated up to 100 times and the possibility of finding drug metabolites in urine is high. Targeted sampling is not only useful in sample selection in toxicology laboratories but also, spends fewer resources on detection, is cost-effective, and is in line with environmental considerations.

description: In the presented work, we studied the alterations of optical properties and electrical conductivity of polyimide (PI) that had been irradiated by an electron dose similar to that of Geosynchronous Earth Orbit (GEO) - like environment. We correlate these material properties to the underlying chemical changes that occur in PI. Several complimentary characterization techniques were utilized to qualify and quantify radiation induced chemical changes in the material, including the directionalhemispherical reflectance (DHR) technique coupled with IR absorption/reflection spectroscopy and dark resistivity measurements.

The mapping procedures are performed at the intersections of the domains. The results of the numerical study are presented. It was shown that the values of the bulk velocity and the hybrid method is in excellent agreement with the tabulated data.
Under the bitumen the river

description: My spatial practice takes a spiral path that links dream, imagination, my body and the viewer. Sensorial experiences, spatial patterns and objects emerge from the images and ideas that surface and take form from this multidimensional matrix. My work is informed by non-rational ways of knowing and perceiving and the focus of this project will be to explore areas of non–rational perceptions and how they translate into artworks through the use of every day materials such as plaster, gelflex, agar, sisal, pencil and paper.

My objective is to create an experience in the form of an installation which will involve aural, tactile and visual components.

The work will draw on:
• Recording and exploration of dream.
• The imagination that is rooted in archetypal images and cultural myths and facilitates my capacity to work with images.
• My body as the point of reference through which the dreams, imagination, senses, ideas and materials come together and are translated into forms, patterns and events.
• My interaction with every day materials, procedures, techniques and technology.
• My position as viewer offering me a cohesive understanding of the process.

The dreams will be recorded in a diary and the images will be amplified by drawings, textual and visual research and connection with further dreams. This is a generative process distilling images, spatial ideas and forms that underlies and defines the work as it takes shape.

The imaginative process allows for ambiguities by drawing on an amalgam of images, materials, ideas, thoughts, forms and spatial considerations making connections between them. I create the potential for ambiguous readings for example work which is at once attractive and repulsive. I will investigate this aspect of the liminal in my work with reference to artists Carolee Schneemann, Anne Hamilton and Eva Hesse. My work references the body and its physical processes in a similar way to Eva Hesse, Carolee Schneemann and Kiki Smith. This creates a visceral and proprioceptive relationship between the work and the viewer. Research via provisional performance/installations will document this interaction and these observations will be utilised in the finished work. The outcome will be an installation that will give presence and form to dream, imagination and body through the use of every day materials, offering the participants an experiential mode of non-rational perception. The installation will be an imagined topography created from the interaction and dialogue between projected images, aural landscapes, tactile surfaces and spatial constructions.

description: Hypersonic vehicles need to withstand high thermal loads during their mission. In case of very high energy flows ablative materials are used to build a Thermal Protection System (TPS). The outgassing due to the pyrolysis of the TPS directly affects the boundary layer stability. This paper studies the effect of wall blowing under controlled conditions, such as porous surfaces, and propose a model for a continuously blowing surface, thus mimicking the behavior of an ablative heat shield. The two models displays a similar shift to lower frequencies for the instabilities growth rate peak and an increased instability of the boundary layer.
