Microbiological detoxification of hazardous organic pollutants is highly promising, but its reliable implementation requires a sophisticated understanding of several different substrate types and how they interact. This paper carefully defines the substrate types and explains how their interactions affect the bacteria's electron and energy flows, information flow, and degradative activity. For example, primary substrates, which are essential for growth and maintenance of the bacteria, also interact with degradation of specific hazardous pollutants by being inducers, inhibitors, and direct or indirect cosubstrates. The target contaminants, which often are secondary substrates, also have the interactive roles of self-inhibitor, inhibitor of primary-substrate utilization, inducer, and a part of an aggregate primary substrate.

Fiber Bragg grating (FBG) sensors have been applied to assess strains, stresses, loads, corrosion, and temperature for structural health monitoring (SHM) of steel infrastructure, such as buildings, bridges, and pipelines. Since a single FBG sensor measures a particular parameter at a local spot, it is challenging to detect different types of anomalies and interactions of anomalies. This paper presents an approach to assess interactive anomalies caused by mechanical loading and corrosion on epoxy coated steel substrates using FBG sensors in real time. Experiments were performed by comparing the monitored center wavelength changes in the conditions with loading only, corrosion only, and simultaneous loading and corrosion. The theoretical and experimental results indicated that there were significant interactive influences between loading and corrosion for steel substrates. Loading accelerated the progress of corrosion for the epoxy coated steel substrate, especially when delamination in the epoxy coating was noticed. Through the real-time monitoring from the FBG sensors, the interactions between the anomalies induced by the loading and corrosion can be quantitatively evaluated through the corrosion depth and the loading contact length. These fundamental understandings of the interactions of different anomalies on steel structures can provide valuable information to engineers for better management of steel structures.

The human genome contains nearly 100 deubiquitinating enzymes (DUBs) responsible for removing ubiquitin moieties from a large variety of substrates. Which DUBs are responsible for targeting which substrates remain mostly unknown. Here we implement the bioUb approach to identify DUB substrates in a systematic manner, combining gene silencing and proteomics analyses. Silencing of individual DUB enzymes is used to reduce their ubiquitin deconjugating activity, leading to an increase of the ubiquitination of their substrates, which can then be isolated and identified. We report here quantitative proteomic data of the putative substrates of 5 human DUBs. Furthermore, we have built a novel interactive database of DUB substrates to provide easy access to our data and collect DUB proteome data from other groups as a reference resource in the DUB substrates research field.

We investigated the effects of nitrogen, phosphorus, and light on periphyton in a clear oligotrophic lake. Experimental treatments consisted of three levels each of nitrogen, phosphorus, and light in a three-way factorial design. Nitrogen and phosphorus concentrations were manipulated using nutrient-diffusing clay substrates; light levels were manipulated with shade cloth. Periphyton biovolume and cell densities increased significantly with both nitrogen and phosphorus enrichment but were not affected by shading. Phosphorus enrichment increased periphyton accumulation only when nitrogen levels were high, indicating a significant interactive effect between nitrogen and phosphorus. Differences in species composition among treatments were mostly due to changes in the diatoms Nitzschia palea and Rhopalodia gibba. Ambient and phosphorus-enriched substrates were dominated by R. gibba, which contains a nitrogen-fixing endosymbiont, and blue-green algae. Nitrogen enrichment and nitrogen and phosphorus in combination resulted in an assemblage dominated by N. palea. Unshaded and highly shaded substrates were dominated by N. palea and Achnanthes minutissima, but the medium-shade substrates were dominated by R. gibba.

Variations in substrate chemistry and the micro-structure were shown to have a significant effect on the biology of human mesenchymal stromal cells (hMSCs). This occurs when differences in the surface properties indirectly modulate pathways within numerous signaling networks that control cell fate. To understand how the surface features affect hMSC gene expression, we performed RNA-sequencing analysis of bone marrow-derived hMSCs cultured on tissue culture-treated polystyrene (TCP) and poly(l-lactide) (PLLA) based substrates of differing topography (Fl: flat and Fs: fibrous) and chemistry (Pr: pristine and Am: aminated). Whilst 80% of gene expression remained similar for cells cultured on test substrates, the analysis of differentially expressed genes (DEGs) revealed that surface topography significantly altered gene expression more than surface chemistry. The Fl and Fs topologies introduced opposite directional alternations in gene expression when compared to TCP control. In addition, the effect of chemical treatment interacted with that of topography in a synergistic manner with the Pr samples promoting more DEGs than Am samples in all gene ontology function groups. These findings not only highlight the significance of the culture surface on regulating the overall gene expression profile but also provide novel insights into cell-material interactions that could help further design the next-generation biomaterials to facilitate hMSC applications. At the same time, further studies are required to investigate whether or not the observations noted correlate with subsequent protein expression and functionality of cells.

Plant polyphenolics are receiving increased attention for their influences on belowground processes. Tannins are of particular interest because of their predominance in natural systems, their wide variation in both quality and quantity, and their protein-binding abilities. Current theory holds that simple phenolics increase microbial activity by acting as carbon substrates, while larger tannins decrease microbial activity by binding with organic nitrogen such as proteins. Here, we present results from a simple microcosm experiment that demonstrates that the influence of condensed tannins on soil respiration depends on the availability of additional carbon substrates. We purified tannins from trembling aspen ( Populus tremuloides Michx.) and crossed three levels of tannin additions with three levels of cellulose additions in laboratory microcosms. Soil respiration was measured over 36 days. In the absence of cellulose, high amounts of condensed tannins increased cumulative soil respiration. In the presence of abundant cellulose, condensed tannins decreased cumulative soil respiration. The positive and negative effects of purified tannins on soil respiration are time dependent, such that initial respiration is likely tannin induced, while later respiration is cellulose induced and tannin limited.

Abstract Aims Environmental heterogeneity affects the performance of clonal aquatic plants. Few researchers integrated two aspects of heterogeneity into the study of clonal plant ecology. The aims of the present study are to (i) test whether different substrate heterogeneity and submergence exert similar effects on plant performance and (ii) explore the foraging behaviour. Methods In this study, Scirpus yagara was subjected to multiple levels of substrate heterogeneity and submergence. Substrate treatments included one homogeneous substrate and three heterogeneous substrates (two-patch, four-patch and eight-patch). Water level treatments included 0, 10 and 30 cm. Traits including ramet number, generation number, leaf number, bulb number, ramet height, culm length, rhizome length, clonal radius, spacer length, spacer thickness, total biomass, biomass of bulbs and biomass per bulb were measured. Important Findings Deeper water levels significantly reduced variables associated with growth such as ramet number, generation number, leaf number and bulb number, while substrate patchiness induced significant variations in traits such as spacer length and spacer thickness. Significant interactive effects of the two factors were found for ramet number, leaf number and spacer length. Scirpus yagara showed colonization towards the lake sediment patch in two-patch and four-patch substrates, and more structures were placed in the lake sediment patch. Especially for the two-patch substrate, all structures occupied the lake sediment patch. Two-sided intrusion was observed in the eight-patch substrate, which induced an even allocation of structures in different patches. The foraging behaviour was correlated with the patch size.

Dans le monde numérique comme dans le monde physique, nos interactions avec les objets laissent des traces qui racontent l'histoire qui les a façonnés au fil du temps. Ces données historiques peuvent être consultées par les utilisateurs afin de mieux comprendre les étapes qui ont conduit à l'état actuel de leur système. Elles peuvent également être re-documentées afin d'arranger l'historique d'une manière plus compréhensible pour les utilisateurs. Dans des environnements collaboratifs, les utilisateurs peuvent être amenés à partager ces données, afin de mieux coordonner ou synchroniser leur travail d'équipe.Des travaux antérieurs ont tenté de démontrer les avantages des historiques partagés entre applications, mais les implémentations actu- elles des historiques dans les systèmes interactifs continuent de confiner les historiques à leur application d'origine.Les utilisateurs ne peuvent pas croiser leur historiques pour corréler les événements qui se sont produits dans différentes applications. Dans cette thèse, je montre que concevoir des historiques de l'interaction pouvant être partagés entre les applications et les utilisateurs faciliterait la navigation, la compréhension et la réutilisation des données historiques. J'ancre le début de mes travaux dans le cas de l'écriture collaborative afin d'explorer des écologies de traces et des usages familiers, mais néanmoins complexes. J'identifie les pratiques récurrentes et les problèmes liés à l'utilisation des données historiques en interrogeant des utilisateurs habitués de l'écriture collaborative, et je mène plusieurs activités de conception basées sur les observations qui en découlent. Je décris ensuite un premier système en tant que preuve de concept intégrant deux outils résultant de ces activités de conception. Ce système intègre également la première itération d'une structure unique pour les données d'historique partagées entre applications et utilisateurs. Les résultats des études utilisateurs menées sur ce système montrent que ces derniers expriment effectivement le besoin de disposer d'historiques d'interaction unifiés et personnalisables. En compilant les données recueillies au cours de ces activités de recherche et en me basant sur des travaux antérieurs concernant les "médias dynamiques partageables" et les substrats d'interaction, je décris un cadre permettant de concevoir des historiques d'interaction plus flexibles. Je présente Steps, une structure d'unification des données historiques qui intègre un noyau d'attributs descriptifs qui préserve l'intégrité d'une trace entre les applications, et des attributs contextuels extensibles qui permettent aux utilisateurs de modeler leurs historiques en fonction de leurs besoins. Je présente ensuite OneTrace, un prototype basé sur les Steps. Son implémentation suit mon cadre descriptif pour les historiques inter-applications et définit l'historique comme un matériau numérique à façonner par l'utilisation d'outils dédiés. Je discute des opportunités offertes par cette approche pour réaliser un changement de paradigme sur la façon dont nous concevons les historiques et leurs outils
In the digital world, as in the physical world, our interactions with objects leave traces that tell the story of the actions that shaped these objects over time. This historical data can be accessed by end users to help them better understand the steps that led to the current state of their system. These traces can also be reused for activities such as re-documenting their own history to arrange it in a way that they find more understandable. Users may also be led to share these data in collaborative environments, to better coordinate and synchronize their work. While previous work has attempted to show the benefits of cross-application histories, current implementations of interaction histories in interactive systems tend to tie history data to their source application. This prevents users from cross-referencing historical data to review and correlate events that occurred in different applications.In this thesis, I argue that designing interaction histories that can be shared among applications and users would support browsing, understanding and reusing historical data. I first ground my work in the use case of collaborative writing to explore relatable yet complex traces ecologies and interaction history use. I identify recurring practices and issues with the use of history data by interviewing knowledge workers and conducting several design activities based on these observations. I describe a first proof-of-concept system integrating two history instruments resulting from these design activities, and the first iteration of a unifying structure for historical data to be shared among applications and users. The results of user studies show that users indeed express a need for unified and customizable interaction histories.Compiling the data gathered during these research activities and based on previous works about “Dynamic Shareable Media” and the Interaction Substrates and Instruments model, I describe a framework to help create more flexible interaction histories. The goal is to describe how to design interaction history systems that would help users take control of their historical data. I introduce Steps, a structure for unifying historical data that includes descriptive core attributes to preserve the integrity of a trace across applications, and extensible contextual attributes that let users reshape their histories to suit their needs. I then introduce OneTrace, a proof-of-concept prototype based on Steps that follows my descriptive framework for cross-application histories and defines interaction histories as digital material to be shaped by digital tool use. I discuss the opportunities offered by this approach to support a shift in paradigm on how we design and interact with interaction histories

Studies have demonstrated dissociable effects of nicotine alone versus in combination with ethanol on learning, and these effects may depend on different neural substrates. Furthermore, the effects of nicotine in different brain areas may produce other behavioral changes - such as changes in anxiety - that alter learning. This research examines the interactive effects of ethanol and nicotine on learning, anxiety, and locomotion, and the dissociation of these effects by brain area. Specifically, we examine the interactive effects of systemic ethanol with nicotine infusion into the dorsal hippocampus, ventral hippocampus, or anterior cingulate on contextual and cued fear conditioning and the plus-maze discriminative avoidance task (PMDAT). In addition, we use dihydro-beta-erythroidine (DHbetaE), a nicotinic receptor antagonist, to examine the involvement of acetylcholingeric nicotinic receptors (nAChRs) in the effects of ethanol alone and in the mediation of ethanol-induced changes by nicotine. In the PMDAT, we examine whether caffeine produces the same effects as nicotine in the PMDAT. In fear conditioning, nicotine acts in the dorsal hippocampus to enhance contextual fear conditioning and in the anterior cingulate to reverse ethanol-induced contextual and cued fear conditioning deficits through inactivation of high-affinity beta2 subunit-containing nAChRs. In the PMDAT, ethanol produces learning deficits, anxiolysis, and increased locomotion, and nicotine reverses the effects of ethanol. Although caffeine and ethanol interact to modulate behavior in the PMDAT, caffeine fails to reverse ethanol-induced learning deficits. Finally, the effects of nicotine and ethanol, both alone and in combination, on learning, anxiety, and locomotion depend on distinct neural substrates. Nicotine acts in the anterior cingulate to reverse ethanol-induced learning deficits but produces diverse effects on anxiety that vary across all three brain areas.

Current methods of bone repair rely on autografts (bone from a donor site) and allografts (bone from human cadaver). However, these methods are plagued with disadvantages. There is a clear and urgent need to provide alternatives for regenerating and repairing bone. Bone is known to be one of the many connective tissues in the body that are responsive to exogenous electrical stimulation. Based on this principle, this thesis explores the potential of using an electrically conducting polymer, polypyrrole, as a substrate for bone regeneration. Optically transparent thin films of polypyrrole, with a polyanionic dopant, poly(styrenesulfonate), were synthesized electrochemically and characterized by X-Ray Photoelectron Spectroscopy, UV/VIS spectroscopy, Scanning Electron Microscopy and by electrical conductivity measurements. In this study, Bone Marrow Stromal Cells (BMSC), which are the progenitor cells to bone cells (osteoblasts), were used as the in vitro model system. Their viability, proliferation and differentiation capabilities were evaluated on polypyrrole, in the absence and presence of electrical stimulation. Results indicate that polypyrrole is ideally suited as a substratum for BMSC growth and differentiation. The application of an electrical stimulus through the polypyrrole substrate was found to induce the differentiation of BMSC towards an osteogenic lineage. Thus, polypyrrole, by virtue of its conductive properties, its in vitro biocompatibility and its flexibility in altering surface characteristics, has an exciting potential as a suitable interactive substrate for bone regeneration.

Current problems on the interaction of complex liquids (i.e. droplets or foams) with complex surfaces (i.e. soft deformable or porous surfaces) are addressed in the following areas: (1) wetting of deformable substrates and surface forces, (2) kinetics of wetting and spreading of non-Newtonian liquids over porous substrates, (3) kinetics of spreading of non-Newtonian solutions over hair, (4) free drainage of foams produced from non-Newtonian solutions, and (5) foam drainage placed on porous substrates. Equilibrium of liquid droplets on deformable substrates was investigated and the effect of disjoining pressure action in the vicinity of the apparent three phase contact line was taken into account. It was proven that the deformation of soft solids is determined by the action of surface forces inside the transition zone. Spreading/imbibition of blood, which is a power law shear thinning non-Newtonian liquid, over a dry porous layer was investigated from both theoretical and experimental points of view. It was found that blood droplet spreading/imbibition over porous substrates shows two different behaviours: (i) partial wetting case with three subsequent stages: initial fast spreading, constant maximum droplet base and the shrinkage of the droplet base; (ii) complete wetting case with only two stages: initial fast spreading and the shrinkage of the droplet base. The wetting of hair tresses by aqueous solutions of two commercially available polymers, AculynTM 22 (A22) and AculynTM 33 (A33) was investigated experimentally. Both A22 and A33 solutions demonstrate well pronounced shear thinning behaviour. Initial contact angle of the A22 and A33 solutions on hair tresses was about 100o. The A22 droplets remained on the hair tress after spreading for at least half an hour. However, a fast penetration of the A33 droplets inside the hair tresses was observed when advancing contact angle in the course of spreading reached a critical value of about 60o. This could be explained by Cassie-Wenzel wetting transition which is caused by filling the pores inside the porous media by liquid. The influence of non-Newtonian rheology of A22 and A33 solutions on foam drainage was also investigated experimentally and a new theory of foam drainage was presented for the case of free drainage. For lowly viscous polymeric solutions and under the assumption of rigid surface of the Plateau border, the predicted values of the time evolution of the foam height and liquid content were in good agreement with the experimental data. However, in the case of highly viscous solutions an interfacial mobility at the surface of the Plateau border has to be taken into account. A completely new theory of foam drainage placed on porous substrate was developed. It was found that there are three different regimes of the process: (i) a rapid imbibition, the imbibition into the porous substrate dominates as compared with the foam drainage; (ii) an intermediate imbibition, that is, the imbibition into the porous substrate and the rate of drainage are comparable; (iii) a slow imbibition, the rate of drainage inside the foam is higher than the imbibition into the porous substrate for a period of time and a free liquid layer is formed over the porous substrate.

In this project, the interaction between polyethylene glycol modified (PEG-ylated) lipid nanoparticles and silica substrates was studied to find out how this interaction was affected by bulk concentration, temperature and the composition of particles. One kind of lipodisk and four kinds of PEG-ylated liposome were prepared from lipid films and characterized by quartz crystal microbalance with dissipation monitoring (QCM-D) instrument mounted with silica sensor. The detailed information of particle-silica interaction could be obtained from the raw data, frequency and dissipation values, and the adsorbed mass surface density calculated from the raw data. Lipodisks could be immobilized on the silica surface. Whether they would be rinsed away by PBS buffer was influenced by both the bulk concentration and temperature. The way of their binding could change and the changing process was affected by temperature. PEG-ylated liposomes could also be immobilized on the silica surface, and they could break and spread to form supported lipid bilayer in certain conditions, for example, the changing of temperature or the using of certain lipids. Supported lipid bilayers were created with high reproducibility in this project, which could be very useful to the future study of transmembrane proteins functions and lipodisk properties.

The monograph explores the problem of the universal-poetic nature of human spirituality and education as a reality that takes into account the above about a person. The universal-poetic in education is associated with the abandonment of the purposeful component in the pedagogical process (as the dominant of education) and the appeal to the imaginative-idealistic interaction of the teacher and the pupil, during which the discovery and deployment of universal-poetic semantics and intentions in the student is maintained. The methodology in the work is the idealistic-substrate reflection of A.A. Gagaev. It is addressed to specialists and students studying the problems of pedagogy, as well as to anyone interested in the phenomenon of man and his upbringing.

This article analyzes the electronic structure of epitaxial graphene using angle-resolved photoemission spectroscopy (ARPES). It first describes how the carbon atoms in graphene are arranged before discussing the growth and characterization of graphene samples. It then considers the electronic structure of epitaxial graphene, along with the gap opening in single-layer epitaxial graphene. It also examines possible mechanisms for the gap opening in graphene, including quantum confinement, mixing of the states between the Brillouin zone corner K points induced by scattering, and hybridization of the valence and conduction bands caused by symmetry breaking in carbon sublattices. Clear deviations from the conical dispersions are observed near the Diracpoint energy, which can be interpreted as a gap opening attributed to graphene–substrate interaction. Graphene–substrate interaction is thus a promising route for engineering the bandgap in graphene.

This article focuses on surface and interface superconductivity, a pivotal area of mesoscopic superconductivity. It discusses theoretical ideas regarding superconductivity in the 2D limit; pairing symmetry in systems with broken inversion symmetry and in the presence of Rashba spin–orbit interaction; and coupling of substrate phonon modes to layer electronic states to induce or enhance the superconducting condensate. It also reviews the experimental ongoing efforts to fabricate, characterize, and measure these systems, with particular emphasis on oxide materials. Superconductivity in two dimensions, in ultra-thin metals on Si(111), and at the LaAlO3/SrTiO3 interface is examined. The article concludes with an analysis of theoretical propositions aimed at realizing and testing novel superconducting states occurring at the surfaces and interfaces.

Understanding our brains can enrich our understanding of the ways we act and interact in a complex world, and how our experience of the built environment helps shape who we are and yet can be shaped by us in turn. This book presents action-oriented perception, memory, and imagination as keys to unlocking the neuroscience of the experience and design of architecture, and explores what it might mean for buildings to have “brains.” It offers a conversation addressed not only to architects and scientists but also to all who share a fascination with the brains within them and the buildings around them. Analysis of famous buildings and of homely examples introduces concepts like aesthetics, affordances, atmosphere, construction, manual action, scripts, and wayfinding, and the search for their neural substrates. It explores how evolution shaped a language-ready brain that is also architecture-ready. Case studies of the Guggenheim Museum Bilbao and the Sydney Opera House introduce an account of how the brains and minds of architects operate, pursuing the idea that memory and imagination are interacting forms of mental construction, but that architectural design must eventually reach a form that can guide the physical construction of buildings. All these concerns set new challenges for collaboration between architects and neuroscientists, and for further research on the brains of humans and animals.

AbstractThe RNA exosome complex functions in both the accurate processing and rapid degradation of many classes of RNA in eukaryotes and Archaea. Functional and structural analyses indicate that RNA can either be threaded through the central channel of the exosome or more directly access the active sites of the ribonucleases Rrp44 and Rrp6, but in most cases, it remains unclear how many substrates follow each pathway in vivo. Here we describe the method for using an UV cross-linking technique termed CRAC to generate stringent, transcriptome-wide mapping of exosome–substrate interaction sites in vivo and at base-pair resolution.

AbstractSpray-wall interactions take place in many technical applications such as spray cooling, combustion processes, cleaning, wetting of surfaces, coating and painting, etc. The outcome of drop impact onto hot surfaces depends on a variety of parameters like for example material and thermal properties of the liquid and wall, substrate wetting properties, surrounding conditions which determine the saturation temperature, spray impact parameters and surface temperature. The aim of the current project is to improve knowledge of the underlying physics of spray-wall interactions. As an important step towards spray impact modeling first a single drop impact onto hot substrates is considered in detail. Various regimes of single drop impact, such as thermal atomization, magic carpet breakup, nucleate boiling and thermosuperrepellency, observed at different wall temperatures, ambient pressures and impact velocities, have been investigated experimentally and modelled theoretically during the project period. The heat flux, an important parameter for spray cooling, has been modeled not only for single drop impacts but also for sprays within many regimes. The models show a good agreement with experimental data as well as data from literature.

AbstractThis chapter presents the interaction between carbon free active and carbon bonded reactive ceramic filter materials and molten iron by utilizing the sessile drop method. The most of carbon free ceramic filter materials showed non-reactive system during the interaction. After the interaction, the number, type, and the size of the non-metallic inclusions were registered with the aid of ASPEX analysis. On the other hand, the carbon bonded materials showed a series of phenomenon during the interaction including the formation of oxide layers covered on the iron droplet and whiskers on the surface of the sample droplets and substrates. To explain these phenomena, the stability of the oxides was calculated. The calculated results indicate that the oxides that consisted of substrates could decompose under the present experimental conditions.

The work considers the construction of a modern digital platform for supercomputer modeling the problems of particles deposition on substrates. The web-based approach is proposed that makes it possible to form the unified user system for carrying out the full cycle of numerical calculation, including the configuration of applied applications, their launch on remote computing resources, monitoring of the task, analysis of the results, and interactive visualization. At the same time, the interaction with supercomputers and clusters is implemented through a graphical interface that does not require to have additional software, except for a web browser. Another advantage is the possibility of conducting a multi-user computational experiment, arising from the natural principles of building client-server platforms, in which specialists from different fields can access up-to-date data obtained during modeling. The digital web platform has been tested on KIAM clusters, and it is also used for group training of MIPT students in modern information technologies. This work is devoted to the discussion of the general architecture, the technological stack and the resulting user interface.

Abstract High Velocity Oxygen Fuel Process (HVOF) involves supersonic two-phase flow of gas-solid particles. Two kinds of shocks are formed in a typical HVOF process. Adjustment of the over-expanded flow to the atmospheric pressure at the exit of the nozzle results in formation of shock diamonds while high speed flow impingement on a substrate creates bow shock. The latter is found to be responsible for deviation of the injected particles from their trajectories near the substrate which significantly reduces the chance of some particles landing on the substrate. An attempt is made to study the behavior of particle trajectory as it interacts with the bow shock formed near the substrate. The strength and location of bow shock was found to vary for different substrate geometries and stand-off distances. In this work, various particle sizes impinging on substrates with various configurations (flat, concave and convex) are simulated and the effect of shock diamonds and bow-shock, on particle trajectory is studied.

Epitaxial lift-off can be effectively used to transfer thin-film semiconductor layers from their parent substrate to foreign substrates that are not necessarily made of semiconductor material.1 The transferred films are bonded, without glue, to the target substrate by van der Waals forces. The potential of this technique is greatly enhanced by grafting semiconductor layers directly onto substrates with optical waveguide circuits and, additionally, by establishing optical interaction between the two.

Surface phenomena in printing are extremely important for understanding and optimizing the interaction of materials involved in the process of graphic reproduction. In order to protect absorbent printing substrates from moisture penetration, to strengthen mechanical properties or to ensure better adhesion of the printing ink to the substrate, the substrates are often coated with protective coatings (primers) before printing. The adhesion parameters between the coating and the printing ink then become extremely important for assessing the durability, but also the quality of the print. In this research, biodegradable primers (polycaprolactone and polylactic acid) were applied on a board substrate with the primary aim of reducing the permeability to water vapour in combination with printed ink layers. Two types of water-based screen printing inks were printed on the primed substrates: ink prepared using the transparent base, and the ink prepared using the opaque white base. Two meshes with different screen count were used (32 l/cm and 60 l/cm). The research focused on the possibility of reducing the water vapour transmission rate using the inks and biodegradable primers, and at the same time analysing the interaction of biodegradable primers and printing inks by determining the surface and interfacial properties in the "printing substrate-primer-printing ink" system. The results of the research have contributed to the optimization of the screen-print quality on the primed absorbent and porous substrates.

Abstract Supersonic, two-phase flow of a gas/particle mixture directed towards a substrate may enable the deposition of "cold" particles onto a "cold" substrate under certain conditions. The method is commonly known as Cold Gas Dynamic Deposition or Cold Spray. Current research shows that copper can be deposited within a wide range of parameters and velocity regimes, whereas the deposition of other materials may involve difficulties depending on the material properties and substrate characteristics. Although particle velocity is recognized as being the key factor in the deposition of particles with the cold spray process, it alone cannot describe the state of the particle prior to and during impact. A simple analysis shows that the impulse of particles with equal particle velocity and size depends significantly on its density. For common engineering metals, an interval varying by up to a factor of 5 is possible considering, for example, magnesium and molybdenum. The impact force, directly dependent on the particle's impulse, governs the pressures generated during impact. In a simplified calculation, pressure values of around 3000 MPa can be very easily determined. While the particle impulse accounts for the degree of interaction - partial or complete deformation - the particle's and the substrate's lattice structure and its capacity to deform determine the type of particle substrate interaction. Depending on these properties, the substrate, the particle or both will be deformed. Evaluating impact experiments shows distinct differences between the impacts of copper, steel and aluminum particles on aluminum and steel substrates. The paper presented may be seen as a contribution to the discussion of a theory to evaluate coating and substrate combinations prior to spraying in order to predict bonding and coating build-up or to offer guidance concerning the optimum parameter set for deposition.

Self-assembly of carbon nanotubes (CNTs) on silicon substrates has myriad applications including nanotube based electrochemical energy conversion and storage devices, such as batteries and super-capacitors. Patterned assembly of CNTs is required in order to control the effective electrical conductivity and mechanical properties of these devices and achieve substantial improvement in their performance. Solution-based self-assembly of CNTs provides a cost-effective means to synthesize uniform vertically or horizontally aligned nanostructures on top of substrates. However, self-assembly of CNTs is a complex dynamical process that involves intermolecular interaction between the CNTs and that between the nanotubes and the substrate as well as solvent molecules. The transport properties of CNTs and solvents also play an important role. The scientific literature lacks detailed study of understanding the mechanism of self-assembly of CNTs on substrates during synthesis process. Often times, nanotubes are functionalized in an effort to make them more soluble and induce partial charges to control the self-assembly. Some of the key factors that govern the transportation and self-assembly of functionalized CNTs are surface charge density on substrate and electrostatic interaction of the functionalized CNTs with the substrate. In an effort to mimic the conditions during the synthesis of carbon nanomaterials on silicon substrate, we have employed molecular dynamics simulations to simulate both pure and functionalized CNTs sandwiched between silicon substrates in presence of commonly used solvent, water. Our simulations indicate that both pure and functionalized CNTs are not significantly soluble in water and form agglomerates. Our results also illustrate that neither pure nor functionalized CNTs tend to deposit on silicon substrates in water. Results presented in this study provide fundamental insight that can help to understand the agglomeration and orientation of CNTs in water.

Abstract In this study, titania and hydroxyapatite nanopowder mixtures are deposited on medical grade titanium substrates by HVOF spraying. To assess bioperformance, human mesenchymal stem cells (hMSCs) were cultured from 1 to 21 days on the surface of HVOF-sprayed TiO2 and TiO2-HA samples. Plasma sprayed HA and uncoated Ti-6Al-4V substrates were used as controls. The active cultures were evaluated for cell proliferation, cytoskeleton organization, and cell-substrate interaction. The results for HVOF-sprayed TiO2-HA nanocomposite coatings show strong evidence of bone growth, proliferation, and attachment with cell-substrate interaction levels superior to those of air plasma sprayed HA coatings. Although there are no clear explanations for this favorable behavior, the topography and chemical composition of the surface of the coating appear to be playing important roles.

In intensive agriculture, harmful soilborne biotic agents, cause severe damage. These include both typical soilborne (clinical) major pathogens which destroy plants (e.g. Fusarium and Phytophthora pathogens), and subclinical ("minor") pathogens (e.g. Olpidium and Pythium). The latter cause growth retardation and yield decline. The objectives of this study were: (1) To study the behavior of clinical (major) and subclinical (minor) pathogens in plant growth substrate, with emphasis on zoosporic fungi, such as Pythium, Olipidium and Polymyxa. (2) To study the interaction between subclinical pathogens and plants, and those aspects of Pythium biology which are relevant to these systems. (3) To adopt a holistic-integrated approach for control that includes both eradicative and protective measures, based on a knowledge of the pathogens' biology. Zoospores were demonstrated as the primary, if not the sole propagule, responsible for pathogen spread in a recirculating hydroponic cultural system, as verified with P. aphanidermatum and Phytophthora capsici. P. aphanidermatum, in contrast to Phytophthora capsici, can also spread by hyphae from plant-to-plant. Synthetic surfactants, when added to the recirculating nutrient solutions provided 100% control of root rot of peppers by these fungi without any detrimental effects on plant growth or yield. A bacterium which produced a biosurfactant was proved as efficacious as synthetic surfactants in the control of zoosporic plant pathogens in the recirculating hydroponic cultural system. The biosurfactant was identified as a rhamnolipid. Olpidium and Polymyxa are widespread and were determined as subclinical pathogens since they cause growth retardation but no plant mortality. Pythium can induce both phenomena and is an occasional subclinical pathogen. Physiological and ultrastructural studies of the interaction between Olpidium and melon plants showed that this pathogen is not destructive but affects root hairs, respiration and plant nutrition. The infected roots constitute an amplified sink competing with the shoots and eventually leading to growth retardation. Space solarization, by solar heating of the greenhouse, is effective in the sanitation of the greenhouse from residual inoculum and should be used as a component in disease management, along with other strategies.

[Extract from Executive Summary] The competition for space from competing sectors in the coastal waters of Scotland has never been greater and thus there is a growing a need for interactive seascape planning tools that encompass all marine activities. Similarly, the need to gather data to inform decision makers, especially in the fishing industry, has become essential to provide advice on the economic impact on fishing fleets both in terms of alternative conservation measures (e.g. effort limitations, temporal and spatial closures) as well as the overlap with other activities, thereby allowing stakeholders to derive a preferred option. The SIFIDS project was conceived to allow the different relevant data sources to be identified and to allow these data to be collated in one place, rather than as isolated data sets with multiple data owners. The online interactive tool developed as part of the project (Work Package 6) brought together relevant data sets and developed data storage facilities and a user interface to allow various types of user to view and interrogate the data. Some of these data sets were obtained as static layers which could sit as background data e.g. substrate type, UK fishing limits; whilst other data came directly from electronic monitoring systems developed as part of the SIFIDS project. The main non-static data source was Work Package 2, which was collecting data from a sample of volunteer inshore fishing vessels (<12m). This included data on location; time; vessel speed; count, time and position of deployment of strings of creels (or as fleets and pots as they are also known respectively); and a count of how many creels were hauled on these strings. The interactive online tool allowed all the above data to be collated in a specially designed database and displayed in near real time on the web-based application.

Sliding friction on ice and snow is characteristically low at temperatures common on Earth’s surface. This slipperiness underlies efficient sleds, winter sports, and the need for specialized tires. Friction can also play micro-mechanical role affecting ice compressive and crushing strengths. Researchers have proposed several mechanisms thought to govern ice and snow friction, but directly validating the underlying mechanics has been difficult. This may be changing, as instruments capable of micro-scale measurements and imaging are now being brought to bear on friction studies. Nevertheless, given the broad regimes of practical interest (interaction length, temperature, speed, pressure, slider properties, etc.), it may be unrealistic to expect that a single mechanism accounts for why ice and snow are slippery. Because bulk ice, and the ice grains that constitute snow, are solids near their melting point at terrestrial temperatures, most research has focused on whether a lubricating water film forms at the interface with a slider. However, ice is extremely brittle, and dry-contact abrasion and wear at the front of sliders could prevent or delay a transition to lubricated contact. Also, water is a poor lubricant, and lubricating films thick enough to separate surface asperities may not form for many systems of interest. This article aims to assess our knowledge of the mechanics underlying ice and snow friction.

The field application of pipeline repair and rehabilitation coatings can be greatly dependent upon the ambient conditions on the day of the scheduled repair. In some cases, such as the application of FBE at girth welds, temporary shelters can be built over the girth weld area to protect pipe from the elements. However, for the majority of pipeline applications, coatings must be applied to a pipe surface that is not optimized for coating application. Specifically, pipelines which are in service during the repair coating operation will be at the temperature of the product flowing through them regardless of the ambient temperature. This poses a very large problem when the temperature of the pipeline is below the dew point of the ambient air, because condensation will occur continuously on the pipe surface. The objective of this work was to determine the performance implications of applying pipeline repair coatings to wet or damp surfaces. Six liquid repair coatings were applied to steel substrates with varying degrees of surface wetness. Three coatings were standard epoxies; three were specially formulated for wet surface tolerance. The coatings were tested for cathodic disbondment resistance, mechanical strength, and how each coating interacts with water during curing. FTIR and DSC analysis of each coating when mixed and cured in wet conditions (water added to the mix) showed no evidence of water interacting with the coating and changing the chemical structure or the chemical properties. Thus it was concluded that the wet surface tolerant coatings, while manufacturers may claim that they were formulated to absorb and accommodate water, in reality just have a better ability to displace water than standard repair coatings.

Hypothesis and Objectives: We hypothesized that coal combustion products (CCPs), including those created during scrubbing of sulfur dioxide from flue gases, can be used alone or mixed with composted animal manures as effective growth media for plants. Our specific objectives were, therefore, to (1) measure the chemical, physical and hydraulic properties of source materials and prepared mixes, (2) determine the optimum design mix of CCPs and composted animal manures for growth of plants, (3) evaluate the leachate water quality and plant uptake of selected elements from prepared mixes, (4) quantify the interaction between composted animal manures and B concentrations in the mixes, (5) study the availability of P to plants growing in the mixes, and (6) determine the microbial community and siderophores involved in the solubilization of Fe and its transfer to plants. Background: In recent years a major expansion of electricity production by coal combustion has taken place in Israel, the United States and the rest of the world. As a result, a large amount of CCPs are created that include bottom ash, fly ash, flue gas desulfurization (FGD) gypsum and other combustion products. In Israel 100,000 tons of fly ash (10% of total CCPs) are produced each year and in the US a total of 123 million tons of CCPs are produced each year with 71 million tons of fly ash, 18 million tons of bottom ash and 12 million tons of FGD gypsum. Many new scrubbers are being installed and will come on-line in the next 2 to 10 years and this will greatly expand the amount of FGD gypsum. One of the main substrates used in Israel for growth media is volcanic ash (scoria; tuff). The resemblance of bottom coal ash to tuff led us to the assumption that it is possible to substitute tuff with bottom ash. Similarly, bottom ash and FGD gypsum were considered excellent materials for creating growth mixes for agricultural and nursery production uses. In the experiments conducted, bottom ash was studied in Israel and bottom ash, fly ash and FGD gypsum was studied in the US. Major Achievements: In the US, mixes were tested that combine bottom ash, organic amendments (i.e. composts) and FGD gypsum and the best mixes supported growth of tomato, wheat and marigolds that were equal to or better than two commercial mixes used as a positive control. Plants grown on bottom ash in Israel also performed very well and microelements and radionuclides analyses conducted on plants grown on bottom coal ash proved it is safe to ingest the edible organs of these plants. According to these findings, approval to use bottom coal ash for growing vegetables and fruits was issued by the Israeli Ministry of Health. Implications: Bottom coal ash is a suitable substitute for volcanic ash (scoria; tuff) obtained from the Golan Heights as a growth medium in Israel. Recycling of bottom coal ash is more environmentally sustainable than mining a nonrenewable resource. The use of mixes containing CCPs was shown feasible for growing plants in the United States and is now being evaluated at a commercial nursery where red sunset maple trees are being grown in a pot-in-pot production system. In addition, because of the large amount of FGD gypsum that will become available, its use for production of agronomic crops is being expanded due to success of this study.
