description: Abstract

WHO has declared Antimicrobial resistance (AMR) as one of the top global public health and developmental threats. The rising challenge of multidrug resistance (MDR) underscores the urgent need for novel antimicrobial agents to combat infections. In this study, we explored the chemistry of Diphenyl(piperidin-4-yl)methanol (DPP) and its substituted molecules within a unified molecular framework by synthesizing six new derivatives through the alkylation of the piperidine nitrogen of  DPP with various phenacyl halides. The structures of these derivatives were elucidated using EIMS, ¹H-NMR, UV, and FTIR techniques. Agar well disc diffusion method was used to evaluate the antibacterial and antifungal activities of synthesized compounds. Antibacterial assay showed significant zones of inhibition (ZOI ≥ 12 mm) against various bacterial strains. Notably, 4NP and DCP were highly effective against Proteus mirabilis, which causes urinary tract infections and related complications. 4NP also demonstrated significant activity against Staphylococcus aureus and Enterobacter DCP was notably effective against Shigella dysenteriae, responsible for shigellosis. In antifungal assays, 3NP, 4NP, DHP, and DCP surpassed fluconazole in ZOI against various fungal strains. 3NP showed superior inhibition against Candida albicans, indicating potential for treating candidiasis. DCP was effective against Penicillium spp., suggesting potential for treating penicilliosis. 4NP was the most potent, particularly against Aspergillus niger, with a ZOI of 25 mm, nearly double that of fluconazole. SAR analysis indicated that nitro and hydroxyl substitutions enhanced inhibition potential, especially at the para position. The study concludes that the lead molecule DPP and its derivatives, especially 4NP and DCP, exhibit promising antibacterial and antifungal activities, making them potential candidates for treating various infections. Further optimization and in vivo studies are recommended to realize their clinical potential fully.

description: Electromagnetic spectrum can be identified as a resource for the designer, as well as for the manufacturer, from two complementary points of view: first, because it is a good in great demand by many different kind of applications; second, because despite its scarce availability, it may be advantageous to use more spectrum than necessary. This is the case of Spread-Spectrum Systems, those systems in which the transmitted signal is spread over a wide frequency band, much wider, in fact, than the minimum bandwidth required to transmit the information being sent.
Part I of this dissertation deals with Spread-Spectrum Clock Generators (SSCG) aiming at reducing Electro Magnetic Interference (EMI) of clock signals in integrated circuits (IC) design. In particular, the modulation of the clock and the consequent spreading of its spectrum are obtained through a random modulating signal outputted by a chaotic map, i.e. a discrete-time dynamical system showing chaotic behavior. The advantages offered by this kind of modulation are highlighted. Three different prototypes of chaos-based SSCG are presented in all their aspects: design, simulation, and post-fabrication measurements. The third one, operating at a frequency equal to 3GHz, aims at being applied to Serial ATA, standard de facto for fast data transmission to and from Hard Disk Drives.
The most extreme example of spread-spectrum signalling is the emerging ultra-wideband (UWB) technology, which proposes the use of large sections of the radio spectrum at low amplitudes to transmit high-bandwidth digital data.
In part II of the dissertation, two UWB applications are presented, both dealing with the advantages as well as with the challenges of a wide-band system, namely: a chaos-based sequence generation method for reducing Multiple Access Interference (MAI) in Direct Sequence UWB Wireless-Sensor-Networks (WSNs), and design and simulations of a Low-Noise Amplifier (LNA) for impulse radio UWB. This latter topic was studied during a study-abroad period in collaboration with Delft University of Technology, Delft, Netherlands.

description: The Bohr-Sommerfeld quantization rule and the Gamow formula for the width of quasistationary level are generalized by taking into account the relativistic effects, spin and Lorentz structure of interaction potentials. The relativistic quasi-classical theory of ionization of the Coulomb system (V_{Coul}=-ξ/r) by radial-constant long-range scalar (S_{l.r.}=(1-λ)(σr+V_0)) and vector (V_{l.r.}=λ(σr+V_0)) fields is constructed. In the limiting cases the approximated analytical expressions for the position E_r and width Γof below-barrier resonances are obtained. The strong dependence of the width Γof below-barrier resonances on both the bound level energy and the mixing constant λis detected. The simple analytical formulae for asymptotic coefficients of the Dirac radial wave functions at zero and infinity are also obtained.

title: On Thermal Bowing of Concrete Sandwich Wall Panels with Flexible Shear Connectors
Creators: name: Pozo, Fray
Publisher: name: Utah State University
Year: 2018

description: Thermal bowing, often referred as bulging or out-of-plane wall deflection, is a common issue on sandwich panel walls caused by a temperature differential between a building interior temperature and the environment. The stresses caused by temperature changes in concrete members are widely known in the practice of bridge design, but not on sandwich wall panels. For sandwich wall panel applications, it is common to have non-composite panels when the designer expects a high temperature gradient, what yields a less economical design, but reduces the bowing.
This project aimed to validate current assumptions regarding the heat flow in sandwich wall panels and to perform a parametric study of panels subject to thermal loads, varying the concrete layer thickness, panel length, type of shear connector and separation using a commercial finite element analysis software. This study concluded that current design practices either underestimate, in the case of multiplying the classical mechanics values by the reported degree of composite behavior, or overestimate the real value of bowing, by using classical mechanics. A method for determining the percentage of composite action and compute bowing was developed and recommendations addressing the importance of this type of loading were given.
title: Teaching Landscape Construction Using Augmented Reality
Creators: name: Singh, Arshdeep
Publisher: name: Utah State University
Year: 2018

description: This thesis describes the design, development, and evaluation of an interactive Microsoft HoloLens application that projects landscape models in Augmented Reality. The application was developed using the Unity framework and 3D models created in Sketchup. Using the application, students can not only visualize the models in real space but can also interact with the models using gestures. The students can interact with the models using gaze and air-tap gestures.
Application testing was conducted with 21 students from the Landscape Architecture and Environmental Planning department at Utah State University. To evaluate the application, students completed a usability survey after using the application. Students also participated in a focus group. Results indicate that students were excited to use the application and found it helpful for learning landscape construction concepts. Some of the students found the application and the HoloLens device cumbersome to use, and they offered suggestions for how to improve the application. The thesis concludes with recommendations for future work.
title: Semilinear Elliptic Equations in Unbounded Domains
Creators: name: van Heerden, Francois A.
Publisher: name: Utah State University
Year: 2004

description: We studied some semilinear elliptic equations on the entire space R^N. Our approach was variational, and the major obstacle was the breakdown in compactness due to the unboundedness of the domain. First, we considered an asymptotically linear Scltrodinger equation under the presence of a steep potential well. Using Lusternik-Schnirelmann theory, we obtained multiple solutions depending on the interplay between the linear, and nonlinear parts. We also exploited the nodal structure of the solutions. For periodic potentials, we constructed infinitely many homoclinic-type multibump solutions. This recovers the analogues result for the superlinear case. Finally, we introduced weights on the linear and nonlinear parts, and studied how their interact ion affects the local and global compactness of the problem. Our approach is based on the Caffarelli-Kohn-Nirenberg inequalities.
Conoscenza e consapevolezza sugli effetti biologici degli ultrasuoni nella pratica clinica in Italia: risultati di una inchiesta con questionario tra ecografisti della socetà italiana di ultrasonologia in medicina e biologia (S.I.U.M.B.)

description: Background
New potential hazards in the use of ultrasound (US) are implied in new diagnostic applications of
US, such as contrast enhanced US.
Aim
To assess the level of awareness and knowledge on safety issues of clinical use of US among
physicians who are members of the Italian National Society for Ultrasound (SIUMB)
Materials and methods
A questionnaire including 11 multiple choice quiz was sent by e-mail to members of SIUMB, who
preliminarly agreed to participate in this initiative. The answers were received anonimously and
statistically analyzed.
Results
The number of returned valid questionnaires was 97 (8 were considered not valid for less than 10
answers filled). Mean age of the responders was 44 years old, and the average time the physician
has been performing ultrasound examinations was 13 years. The principal workplace (70%) was a
public Hospital. Physicians seemed to know the general definitions of principal safety-parameters,
but few of them knew the definition of specific indexes. There was a general knowledge about the
safe use of ultrasound in obstetrics, but there was a poor knowledge of biological effects of US:
only about 37% answered correctly to questions about damage of vasculature of lung by high
Mechanical Index US investigation and about the increase of temperature under the probe,
according to the thermal indexes.
Conclusion
In conclusion the present findings indicate that greater efforts of National Ultrasound Societies are
warranted in disseminating knowledge about the bio-effects of diagnostic ultrasound modalities
among their members to prevent possible hazards.
title: Linear Operators that Preserve Qualitative Matrix Structures

description: We characterized the group of linear operators that preserve sign-nonsingular matrices over ��(ℝ). Then we extended these results to n show that a linear operator T that strongly preserves L-matrices over ��,�(ℝ) if and only if T preserves L-matrices and T is also one to one on m,n the set of cells. We also characterized the group of linear operators that strongly preserve L-matrices.
In addition, we characterized the group of linear operators that preserve super L- matrices, the subset of L-matrix. Also we investigated linear operators that preserve totally L-matrices, the subset of L-matrix.
Chapters 1 and 2 of this dissertation contain some material of the work done by other researchers on the linear preserver problems and the properties of sign-nonsingular matrices and L-matrix. Characterizations of linear operators in Chapters 3, 4, 5, and 6 of this dissertation are new.
title: A Classification of Real Indecomposable Solvable Lie Algebras of Small Dimension with Codimension One Nilradicals
Creators: name: Parry, Alan R.
Publisher: name: Utah State University
Year: 2007

description: This thesis was concerned with classifying the real indecomposable solvable Lie algebras with codimension one nilradicals of dimensions two through seven. This thesis was organized into three chapters.
In the first, we described the necessary concepts and definitions about Lie algebras as well as a few helpful theorems that are necessary to understand the project. We also reviewed many concepts from linear algebra that are essential to the research.
The second chapter was occupied with a description of how we went about classifying the Lie algebras. In particular, it outlined the basic premise of the classification: that we can use the automorphisms of the nilradical of the Lie algebra to find a basis with the simplest structure equations possible. In addition, it outlined a few other methods that also helped find this basis. Finally, this chapter included a discussion of the canonical forms of certain types of matrices that arose in the project.
The third chapter presented a sample of the classification of the seven-dimensional Lie algebras. In it, we proceeded step-by-step through the classification of the Lie algebras whose nilradical was one of four specifically chosen because they were representative of the different types that arose during the project.
In the appendices, we presented our results in a list of the multiplication tables of the isomorphism classes found.

description: Abstract

Chronic Kidney Disease (CKD) has a severe impact on poor psychological outcomes such as anxiety. Studies addressing anxiety have been used in the targeted population. Unfortunately, none of the studies discussed the therapeutic spiritual-community model (TSCM) in patients with hemodialysis. Therefore, the study intends to evaluate the use of the therapeutic spiritual-community model (TSCM) in patients with hemodialysis. The study used a literature review to assess publications on the therapeutic spiritual-community model (TSCM) in the group of patients. The results highlighted that implementing the therapeutic spiritual-community model (TSCM) with a specific duration is helpful to reduce anxiety. Further study is required to evaluate the intervention with different dosages or duration.

description: Surface transport of inertial particles is investigated by means of the perturbative approach, introduced by Maxey (J. Fluid Mech. 174, 441 (1987)), which is valid in the case the deflections induced on the particle trajectories by the fluid flow can be considered small. We consider a class of compressible random velocity fields, in which the effect of recirculations is modelled by an oscillatory component in the Eulerian time correlation profile. The main issue we address here is whether fluid velocity fluctuations, in particular the effect of recirculation, may produce nontrivial corrections to the streaming particle velocity. Our result is that a small (large) degree of recirculation is associated with a decrease (increase) of streaming with respect to a quiescent fluid. The presence of this effect is confirmed numerically, away from the perturbative limit. Our approach also allows us to calculate the explicit expression for the eddy diffusivity, and to compare the efficiency of diffusive and ballistic transport.

description: Pictograms (also called symbols) are widely used in daily life as a type of visual language, such as transportation venue signs (airport, rail station, etc.), road signs, care symbols on clothing, or direction symbols (Tijus et al., 2007). This shows how symbols can communicate information quickly and effectively. Fundamentally, symbols can be understood, regardless of the person's language or literacy skills. Therefore, people with communication difficulties may benefit from using symbols to comprehend what other people are saying, as well as to express themselves. There are many sets of pictograms available online or in the market as printed cards, some of them are free and some must be purchased. Pictogram sets can be considered in several ways including how pictorial, how guessable, how flexible, how consistent, and how visually complex. Each symbol set has strengths and weaknesses, and the choice of a symbol set should be based on the needs and abilities of the person using AAC.

description: Abstract

The reading performance of pupils in Siha Elementary School is low as reflected in Phil-IRI assessment. In fact, none among the 21 respondents is able to read. This study focused on the effectiveness of Remedial Reading to Non-Readers in Intermediate Level at Siha Elementary School. It aimed to identify the effectiveness of various interventions used in the conduct of remedial reading. It covered 21 pupils from Grades 4, 5 and 6 as the respondents. Composed of 14 males and 7 females. The research looked into the reading level of the respondents and the significant difference after the intervention. This study is a pretest and post-test experimental design. Total enumeration method was utilized, where all pupils from grades 4, 5 and 6 were measured individually in terms of reading skills to determine who among them cannot read. The findings indicated increase from the results of pretest to the post-test. The results of post-test based on computed mean which is 27.14 as their reading level was found significantly higher than the pretest resulted as zero (0). It is recommended that the conduct of remedial reading classes be implemented for the pupils to develop genuine love for reading, supported by varied instructional materials.
title: Identification of Optimal Conditions for Dry Drilling (Analytical Approach to Prediction of the Occurrence of BUE)
Creators: name: Gali, Prasad
Publisher: name: Utah State University
Year: 2003

description: Lubrication is used during the drilling of aluminum to counter the formation of a built-up-edge (BUE), among other reasons. The elimination of the use of lubricants in drilling of aluminum is important because of the associated high costs of cleaning and disassembly involved in lubrication. The optimal conditions sought in this work include the elimination of the use of lubricants along with the possible attainment of a high material removal rate, which could help in reduction of cost and increase productivity at the same time. BUE has been found to be almost always present in the process of metal cutting at low to moderate speeds. It has been found that a necessary condition for the formation of a BUE is the presence of a negative stress gradient away and normal to the tool rake face. The quantitative equivalence of the effects of temperature and strain rate on flow stress described by the Zener-Hollomon parameter (Z) [5]. The relationship between the Zener-Hollomon parameter (Z) and chip flow stress implies that a negative Z gradient could be considered equivalent to a negative stress gradient. A series of computer simulations with varied cutting conditions were analyzed to determine the combination of machining variables which yielded a low predicted BUE preferably with a high material removal rate. The results presented here include cases which have a low predicted BUE as well as a high material removal rate.

description: Muon bremsstrahlung photons converted in front of the DELPHI main tracker (TPC) in dimuon events at LEP1 were studied in two photon kinematic ranges: 0.2 < E_gamma <= 1 GeV and transverse momentum with respect to the parent muon p_T < 40 MeV/c, and 1 < E_gamma <= 10 GeV and p_T < 80 MeV/c . A good agreement of the observed photon rate with predictions from QED for the muon inner bremsstrahlung was found, contrary to the anomalous soft photon excess that has been observed recently in hadronic Z^0 decays. The obtained ratios of the observed signal to the predicted level of the muon bremsstrahlung are 1.06 +/- 0.12 +/- 0.07 in the photon energy range 0.2 < E_gamma <= 1 GeV and 1.04 +/- 0.09 +/- 0.12 in the photon energy range 1 < E_gamma <= 10 GeV. The bremsstrahlung dead cone is observed for the first time in the direct photon production at LEP.

Such a system is archetypic of devices in which transport is governed by a collective mechanism, here charge multiplication by avalanche. We have measured the first 5 cumulants of the probability distribution of the current fluctuations. We show that the charge multiplication factor is distributed according to a power law that is different from that of the usual avalanche below breakdown, when avalanches are well separated.

description: Abstract

Nitrogen pollution in wastewater presents significant environmental and health hazards due to the presence of refractory substances, including phenolic compounds, polycyclic aromatic hydrocarbons, and heterocyclic nitrogenous compounds. Conventional treatment methods are often insufficient for successfully removing these pollutants. This review article provides a comprehensive overview of recent advancements in the treatment of nitrogen-rich wastewater, focusing on heterotrophic nitrification and aerobic denitrification (HNAD) processes. In spite of the potential of HNAD processes, they face challenges related to environmental influences and operational conditions. Conformist methods characteristically necessitate extensive capacity and precise conditions, often leading to inefficiencies. This review outlines the recent developments in HNAD processes and explores their mechanisms, metabolic pathways, and influencing factors, including carbon/nitrogen ratio, dissolved oxygen, temperature, pH, shaking speed, heavy metals, salinity, and antibiotics. The review also highlights the intricacy of treating coking wastewater due to its intractable nature and discusses how biological methods, especially bioaugmentation, can improve biodegradability. Integrated treatment methods are emerging as comprehensive solutions, combining various approaches to enhance efficiency and effectiveness. Furthermore, innovative technologies such as microwave irradiation show assurance for treating coking wastewater. Finally, this review identifies future research directions, emphasizing the need for further inquiry into the HNAD process and its application in real-world wastewater treatment facilities. By consideration the relations between various metabolic activities and optimizing environmental conditions, HNAD processes can be additional developed to offer sustainable and resourceful solutions for nitrogen removal from wastewater.

description: Citation information in scholarly data is an important source of insight into the reception of publications and the scholarly discourse. Outcomes of citation analyses and the applicability of citation based machine learning approaches heavily depend on the completeness of such data. One particular shortcoming of scholarly data nowadays is that non-English publications are often not included in data sets, or that language metadata is not available. Because of this, citations between publications of differing languages (cross-lingual citations) have only been studied to a very limited degree. In this paper, we present an analysis of cross-lingual citations based on over one million English papers, spanning three scientific disciplines and a time span of three decades. Our investigation covers differences between cited languages and disciplines, trends over time, and the usage characteristics as well as impact of cross-lingual citations. Among our findings are an increasing rate of citations to publications written in Chinese, citations being primarily to local non-English languages, and consistency in citation intent between cross- and monolingual citations. To facilitate further research, we make our collected data and source code publicly available.

description: Abstract

This research on community - based policing as a strategy for reducing armed robbery cases in urban areas, was conducted because armed robbery cases have been on the rise. So far, little attempt has been done to reduce armed robbery.  This study was aimed at finding strategies that can be used for reducing armed robbery cases. The researcher utilized a qualitative research strategy during the course of this study. The target population from which the sample of participants was selected was 20 police officers in Harare. In this study it was established that most urban police stations are lacking a befitting community based model to reduce armed robbery cases. Police should undertake activities aimed at reducing crime in the country. The police organization should implement crime prevention strategies such as police patrols, community-based policing and criminal surveillance among others to reduce armed robberies.

description: Network representation learning (NRL) methods have received significant attention over the last years thanks to their success in several graph analysis problems, including node classification, link prediction, and clustering. Such methods aim to map each vertex of the network into a low-dimensional space in a way that the structural information of the network is preserved. Of particular interest are methods based on random walks; such methods transform the network into a collection of node sequences, aiming to learn node representations by predicting the context of each node within the sequence. In this paper, we introduce TNE, a generic framework to enhance the embeddings of nodes acquired by means of random walk-based approaches with topic-based information. Similar to the concept of topical word embeddings in Natural Language Processing, the proposed model first assigns each node to a latent community with the favor of various statistical graph models and community detection methods and then learns the enhanced topic-aware representations. We evaluate our methodology in two downstream tasks: node classification and link prediction. The experimental results demonstrate that by incorporating node and community embeddings, we are able to outperform widely-known baseline NRL models.

The results indicate that the antiferromagnetism of Mn sub-lattice known for the bulk form in the range 100-300 K gets weakened in favor of ferromagnetism in the fine particles. On the basis of this observation, we infer that there are other factors like size (and possibly defects) also play a role to decide the exact nature of magnetic ordering of Mn in this ternary family of compounds, contrasting the traditionally held view that the basal plane Mn-Mn distance is the crucial controlling parameter.

description: The exact mechanisms of the exercise induced adaptations is not lucid, but recent studies have delineated two means of signaling by which the adaptations occur (1) substrate availability signaling (metabolic stress) (2) hormone-receptor signaling. We have decided to specifically investigate two metabolic signaling enzymes [AMP-activated kinase (AMPK) and Sirtuin 1(SIRT1)] and two hormones [Adiponectin and Adrenergic stimulation].Tis based on four papers with the following conclusions: (1)Increase in SIRT1 activity and expression in H9c2 cells treated with phenylephrine is an adaptive response to the hypertrophic stress, mediated by AMPK. (2)The lack of optimal nutritional conditions (energetic substrates) due to a prolonged activation of AMPK can contrast  the establishment of hypertrophy, possibly also by means of the negative modulation of ODC activity. (3) Our findings offer a possibile hypothesis as to the fact the the G allele on site 45 could lead to the increasd risk of Type II diabetes through a decrease in lean body mass. (4) Our results suggest that there is an ADIPOQ gene effect in relation to bone parameters. Statistical analysis show that the presence of the T allele in position 45 favors an  increase in lumbar spine bone mineral content (BMC) when compared to subjects with a G allele substitution, which can be do the the increase in lean body mass in this genotype group.

description: BNE und Digitalisierung – scheinbar ein Widerspruch mögen die eine oder der andere spontan denken. Denn die zunehmende Virtualisierung bedroht immer mehr das reale Erleben von natürlicher, sozialer und wirtschaftlicher Nachhaltigkeit. Aus der Not kann jedoch auch eine Tugend gemacht werden. Der vorliegende Sammelband enthält dazu sowohl Hintergrundgedanken theoretischer Art, verknüpft diese aber in zahlreichen Kapiteln mit unterschiedlich anregenden Anwendungsbeispielen. Die Autorenschaft haben die Pandemiejahre gut genutzt, um in diesem Band eine Reihe interessanter Beiträge zum titelgebenden Thema zusammenzustellen. Das Buch ist entsprechend nicht gedacht, um von vorne nach hinten durchzulesen, um dabei auf 20 mehr oder weniger ähnliche Definitionen einer BNE und einer digitalen Bildung zu stossen. Vielmehr ist die Lektüre etwas zum «Rosinenpicken». Je nach Interesse, Hintergrund und Perspektive stecken die einmal mehr, einmal weniger schmackhaften Rosinen in unterschiedlichen Kapiteln. Diese Rezension stellt deshalb abgesehen von der Einleitung (Kapitel 1) die verschiedenen Kapitel kurz vor und eröffnet dabei jedes Kapitel mit zwei bis drei Stichworten zu den wesentlichsten Inhalten. Dadurch können sich Lesende auch anhand dieser Stichworte auf «Rosinensuche» begeben.

description: The Ultraviolet Coronagraph Spectrometer (UVCS) observed Doppler shifted material of a partial Halo Coronal Mass Ejection (CME) on December 13 2001. The observed ratio of [O V]/O V] is a reliable density diagnostic important for assessing the state of the plasma. Earlier UVCS observations of CMEs found evidence that the ejected plasma is heated long after the eruption. We have investigated the heating rates, which represent a significant fraction of the CME energy budget. The parameterized heating and radiative and adiabatic cooling have been used to evaluate the temperature evolution of the CME material with a time dependent ionization state model. The functional form of a flux rope model for interplanetary magnetic clouds was also used to parameterize the heating. We find that continuous heating is required to match the UVCS observations. To match the O VI-bright knots, a higher heating rate is required such that the heating energy is greater than the kinetic energy. The temperatures for the knots bright in Ly$α$ and C III emission indicate that smaller heating rates are required for those regions. In the context of the flux rope model, about 75% of the magnetic energy must go into heat in order to match the O VI observations. We derive tighter constraints on the heating than earlier analyses, and we show that thermal conduction with the Spitzer conductivity is not sufficient to account for the heating at large heights.

description: Abstract

The growth of active users on online interactive media platforms, such as electronic Word-of-Mouth, has had a significant impact on marketers as customers are more likely to trust unfiltered e-WOM from other consumers than marketer-influenced signals like branding. There is still a debate about the impact of e-WOM on consumer purchasing behaviour; this discrepancy could be attributed to various factors, including the context in which the studies were conducted, the methodological approaches used, and the time and spatial dimensions. Other factors contributing to the lack of consensus include the fact that online content is tailored to different occasions, social groups, and even different brands. The paper seeks to establish what e-WOM is and discuss its relationship with consumers’ buying behaviour process during online buying. The study was quantitative, descriptive, and cross-sectional. The self-administered questionnaires were sent via email to 400 Durban University of Technology staff and students and only 288 questionnaires were received back. A review of the literature revealed a positive relationship between e-WOM and consumer buying behaviour. The empirical findings from the structural equation modelling, which demonstrated a positive, strong correlation between e-WOM and consumer buying behaviour, further support the literature. Marketers must design tactics to increase the likelihood of their businesses creating positive e-WOM in all e-WOM stages and capitalising on the power of any favourable reviews and testimonials received.

description: For many years, psychologists have been trying to find the relationship between perception and different factors of personality. Different experimental techniques were constructed to measure these concepts. One of the tools used to measure personality factors and their effect on perception was the tachistoscope. Through the use of this instrument, words or pictures could be flashed on a screen at varying rates of speed, or illumination. The subject upon watching these flashes, would relate the information which he perceived.

description: Massive stars are "cosmic engines" (cf the title of the IAU Symposium 250). They drive the photometric and chemical evolution of galaxies, inject energy and momentum through stellar winds and supernova explosions, they modify in this way the physical state of the interstellar gas and have an impact on star formation. The evolution of massive stars depends sensitively on the metallicity which has an impact on the intensity of the line driven stellar winds and on rotational mixing. We can distinguish four metallicity regimes: 1.- the Pop III regime $0 \le Z < \sim 10^{-10}$; 2.- The low metallicity regime $10^{-10} \le Z < 0.001$; 3.- The near solar metallicity regime $0.001 \le Z < 0.020$; 4.- The high metallicity regime $0.020 \le Z$. In each of these metallicity ranges, some specific physical processes occur. In this review we shall discuss these physical processes and their consequences for nucleosynthesis and the massive star populations in galaxies. We shall mainly focus on the effects of axial rotation and mass loss by line driven winds, although of course other processes like binarity, magnetic fields, transport processes by internal waves may also play important roles.

description: We investigated the propagation of turbulent fronts in pipe flow at high Reynolds numbers by direct numerical simulation. We used a technique combining a moving frame of reference and an artificial damping to isolate the fronts in short periodic pipes, which enables us to explore the bulk Reynolds number up to Re = $10^5$ with affordable computation power. We measured the propagation speed of the downstream front and observed that a fit of $1.971-(Re/1925)^{-0.825}$ (in unit of bulk speed) well captures this speed above $Re\simeq 5000$. The speed increases monotonically as Re increases, in stark contrast to the decreasing trend above $Re\simeq 10000$ reported by Wygnanski & Champagne (1973). The speed of the upstream front overall agrees with the former studies and $0.024 + (Re/1936)^{-0.528}$ well fits our data and those from the literature. Based on our analysis of the front dynamics, we proposed that both front speeds would keep their respective monotonic trends as the Reynolds number increases further. We show that, at high Reynolds numbers, the local transition at the upstream front tip is via high-azimuthal-wavenumber structures in the high-shear region near the pipe wall, whereas at the downstream front tip is via low-azimuthal-wavenumber structures in the low-shear region near the pipe center. This difference is possibly responsible for the asymmetric speed scalings between the upstream and downstream fronts.
