description: We study the stars of the binary system 16 Cygni to determine with high precision their chemical composition. Knowing that the component B has a detected planet of at least 1.5 Jupiter masses, we investigate if there are chemical peculiarities that could be attributed to planet formation around this star. We perform a differential abundance analysis using high resolution (R = 81,000) and high S/N (~700) CFHT/ESPaDOnS spectra of the 16 Cygni stars and the Sun; the latter was obtained from light reflected of asteroids. We determine differential abundances of the binary components relative to the Sun and between components A and B as well. We achieve a precision of about 0.005 dex and a total error ~0.01 dex for most elements. The effective temperatures and surface gravities found for 16 Cyg A and B are Teff = 5830+/-7 K, log g = 4.30+/-0.02 dex, and Teff = 5751+/-6 K, log g = 4.35+/-0.02 dex, respectively. The component 16 Cyg A has a metallicity ([Fe/H]) higher by 0.047+/-0.005 dex than 16 Cyg B, as well as a microturbulence velocity higher by 0.08 km/s. All elements show abundance differences between the binary components, but while the volatile difference is about 0.03 dex, the refractories differ by more and show a trend with condensation temperature, which could be interpreted as the signature of the rocky accretion core of the giant planet 16 Cyg Bb. We estimate a mass of about 1.5-6 M_Earth for this rocky core, in good agreement with estimates of Jupiter's core.

description: Au travers de l’étude de la région de la Greina, située dans les Alpes centrales, cette recherche s’interroge sur les différentes valeurs qui peuvent être associées aux formes du relief, sur la manière dont ces valeurs peuvent être analysées et sur l’application de cette analyse à une valorisation de la géomorphologie de la région d’étude. Une analyse de la valeur scientifique et des valeurs additionnelles (esthétique, écologique, culturelle et économique) des formes du relief a été effectuée à l’échelle du paysage géomorphologique et des géomorphosites et a permis de montrer que les valeurs additionnelles globales d’un paysage géomorphologique sont généralement différentes par rapport à celles des géomorphosites sélectionnés pour leur valeur scientifique, surtout en ce qui concerne la valeur écologique et culturelle. Les géomorphosites ne constituent donc pas toujours l’échelle spatiale idéale pour apprécier la valeur écologique et culturelle de la géomorphologie d’une région dans son ensemble. Des propositions de valorisation de la géomorphologie de la Greina adressées à différents types de publics ont ensuite été formulées. Il a ainsi été possible de mettre en évidence que l’approche liée aux géomorphosites est utile dans un but de protection et de valorisation de la géomorphologie auprès d’un public de spécialistes d’un domaine des sciences de la Terre, alors qu’elle doit être accompagnée d’une approche plus globale dans un but de valorisation auprès d’autres publics. Cette recherche pose l’accent sur la nécessité d’effectuer des études approfondies concernant l’ensemble des formes du relief, les publics-cible et les méthodes de vulgarisation avant toute valorisation de la géomorphologie d’une région. Elle montre également l’intérêt de l’intégration de la notion de patrimoine dans cette démarche.

description: Le rapport entre les risques géomorphologiques et le tourisme est un thème qui n’a été que peu abordé pour l’instant. Le développement de nouvelles recherches méthodologiques afin de mieux cerner les risques engendrés par les dynamiques géomorphologiques dans les régions touristiques est donc nécessaire. Une nouvelle méthodologie permettant d’évaluer le risque géomorphologique le long des itinéraires pédestres a été développée en Italie. La randonnée pédestre jouissant d’une grande popularité aussi bien auprès des touristes suisses qu’étrangers, ce mémoire se propose d’évaluer le risque géomorphologique sur quatre sentiers pédestres situés dans le Val Ferret (Valais). Comprenant tout d’abord une problématique globale liée aux impacts des changements climatiques dans les Alpes sur le tourisme estival, le mémoire présente ensuite le cadre théorique, méthodologique et géographique dans lequel s’inscrit cette recherche. Le corps du mémoire consiste en l’analyse des quatre sentiers pédestres, analyse effectuée selon un protocole précis, qui comprend notamment une description détaillée de tous les secteurs composant les quatre sentiers étudiés selon six niveaux de difficulté et le danger géomorphologique (nul, faible à résiduel, moyen, élevé). En mettant en relation les éléments géomorphologiques qui peuvent influencer la vulnérabilité touristique et le danger géomorphologique prévisible, il est possible d’attribuer différents degrés de risque (résiduel, faible, moyen et élevé) le long des itinéraires examinés. Cette méthode d’appréciation des sentiers pédestres a donc permis de mettre en évidence les tronçons les plus critiques, qui nécessitent une attention particulière. Un chapitre édicte finalement des recommandations permettant de gérer au mieux les risques le long des itinéraires pédestres alpins.

description: Fluorescence resonance energy transfer (FRET) between two dyes acriflavine (Acf) and rhodamine B (RhB) were investigated in solution and Layer-by-Layer (LbL) self assembled films in presence and absence of clay mineral laponite. UV-Vis absorption and fluorescence spectroscopy studies suggest both the dyes present mainly as monomer in solution and films. Energy transfer occurred from Acf to RhB in solution and LbL films. The energy transfer efficiency increases in presence of clay laponite and the maximum efficiency were 78.17% and 32.54% in clay dispersion and in LbL films respectively. Presence of laponite particles onto LbL film was confirmed by atomic force microscopy investigations with a surface coverage of more than 75%. Energy transfer efficiency was pH sensitive and the energy transfer efficiency varies from 4.5% to 44.45% in mixed dye solution for a change in pH from 3.0 to 12.0. With proper calibration it is possible to use the present system under investigation to sense pH over a wide range of pH from 3.0 to 12.0.

description: Oxygen-enriched combustion is expected to be introduced into small scale to improve the characteristics of micro- or meso-scale combustion. To fully understand the advantages of oxygen-enriched combustion, the ignition characteristics of n-butane/oxygen-enriched air mixtures are studied by the experimental and numerical methods in a heated quartz tube with an inner diameter of 5 mm. The experimental results show that the oxygen enrichment level, equivalence ratio, and flow rate have an important influence on the ignition temperature of the mixed gas in the tube. The ignition temperature decreases with the increasing oxygen enrichment and is strongly affected by oxygen concentration at higher equivalence ratio and lower oxygen enrichment level. In the meanwhile, higher equivalence ratio and lower flow velocity also significantly reduce the ignition temperature in the experimental cases. Furthermore, the increase in the oxygen enrichment level significantly enhances the effect of the equivalence ratio on the ignition temperature while higher flow velocity slightly weakens the effect. The numerical results show that oxygen enrichment is beneficial to the production of OH radicals in pre-ignition period and significantly promotes the oxydehydrogenation reactions of intermediates.

description:  This paper presents a study of a tridimensional low-head hydraulic jump stilling basin by using both physical and numerical models. Laboratory tests up to 15 hours in duration were carried out in a 1.9 m wide and 14 m long flume. Four gates produced a jet with a submerged hydraulic jump in a positive-step stilling basin, after which scour developed in a nearly uniform sand bed. Acoustic Doppler Velocimeter, piezometers and image processing were used to collect the hydrodynamic data, and Reynolds Averaged Navier-Stokes simulations developed in OpenFOAM were tested for validation purposes. Then, the study focused on (1) the temporal evolution of the experimental scour depth downstream the stilling basin and (2) the efficiency of the numerical models to reproduce the interior fields. Regarding the first point, it was found that temporal scour evolution agrees with empirical dimensionless formulation, but differences in magnitude were found, indicating that some variables should be further investigated. The validation of numerical models has shown that the K-Epsilon Standard model is much better than the K-Omega SST counterpart in reproducing velocity fields but similar values were found for turbulent kinetic energy. Pressure fluctuations numerical coefficient also showed values similar to those found by other authors, however lateral flow and Reynolds stress issues appeared because of the tridimensional nature of the case study.

description: This work studies the jamming and percolation of parallel squares in a single-cluster growth model. The Leath-Alexandrowicz method was used to grow a cluster from an active seed site. The sites of a square lattice were occupied by addition of the equal size $k \times k$ squares (E-problem) or a mixture of $k \times k$ and $m \times m$ ($m \leqslant k$) squares (M-problem). The larger $k \times k$ squares were assumed to be active (conductive) and the smaller $m \times m$ squares were assumed to be blocked (non-conductive). For equal size $k \times k$ squares (E-problem) the value of $p_j = 0.638 \pm 0.001$ was obtained for the jamming concentration in the limit of $k\rightarrow\infty$. This value was noticeably larger than that previously reported for a random sequential adsorption model, $p_j = 0.564 \pm 0.002$. It was observed that the value of percolation threshold $p_{\mathrm{c}}$ (i.e., the ratio of the area of active $k \times k$ squares and the total area of $k \times k$ squares in the percolation point) increased with an increase of $k$. For mixture of $k \times k$ and $m \times m$ squares (M-problem), the value of $p_{\mathrm{c}}$ noticeably increased with an increase of $k$ at a fixed value of $m$ and approached 1 at $k\geqslant 10m$. This reflects that percolation of larger active squares in M-problem can be effectively suppressed in the presence of smaller blocked squares.

Bien que diffusé en ligne, il semble en effet contenir les traits d'une expression intime telle qu'elle pourrait apparaître dans un carnet tenu secret. D'autre part, cette diffusion et la visibilité qui en découle amènent à une progressive constitution d'un genre intime. L'analyse d'un corpus constitué de huit blogues cherchera à affirmer ces hypothèses.

description: This study focuses on the illuminated Book of Hours incunabula by the Parisian workshop of the Hardouyns (1500-1500). To carry out a general characterization of the production techniques used by this workshop, the project was divided into three main areas of interest: the historical and social context of the workshop, the definition of the themes represented and the analysis of influences in the composition of the images and the analysis of materials, the techniques and production methodologies. To achieve this global vision, a multidisciplinary approach combining social sciences and technology was adopted. After defining some essential concepts, a historical and social context was carried out, with the framework in which Books of Hours began to be produced in Paris to better understand the history and importance of the Hardouyn brothers’ workshop and its changes over time. To know the themes present in the illustrations, the second chapter identifies fifteen series of engravings designed by celebrated artists, applied across their editions. Most of these sets were known, but some were not, and are here present for the first time. Besides, this work yields new findings on the use and transmission of tools for decoration from other workshops. In the third part, this study employed in-situ, non-invasive, micro-invasive and microdestructive methods to investigate two images, Adoration of the Magi and Printer’s device (UVVis- NIR FORS, h-EDXRF, HSI, DM, IR-photography, IRR, μ-FTIR, SEM-EDS, Py-GCMS, XRMC, DM-IP and IP). The work highlighted that the materials adopted to formulate inks for printing are consistent with the materials referred to wood- and metal-cutting in documentary references. The coloured palette consisted of common pigments in either the French school of manuscript illuminating or the German school of print colouring, revealing a few unusual substances. In the end, the dissertation unveiled the “industrial” character of the Hardouyn editions.

Lgs. 08.11.2021 n. 188 – entrato in vigore il 14.12.2021 – sul rafforzamento di alcuni aspetti della presunzione di innocenza e del diritto di presenziare al processo nei procedimenti penali. Il lavoro analizza le singole disposizioni del nuovo testo di legge alla luce delle corrispondenti previsioni contenute nella direttiva e dell’evoluzione giurisprudenziale, specie quella della Corte europea dei diritti dell’uomo. Il quadro finale consegna un provvedimento con luci ed ombre. Esso è certamente condivisibile nella parte in cui richiama le autorità pubbliche ad un’accurata riflessione sia in ordine all’opportunità di diffondere notizie riguardanti procedimenti penali, sia – e soprattutto – alle modalità con le quali esse vengono offerte, che dovrebbe essere tale da evitare di rappresentare l’indagato o l’imputato anticipatamente come colpevoli pur in mancanza di una decisione di condanna passato in giudicato. Non altrettanto può dirsi, invece, per la decisione di introdurre il nuovo art. 115 bis c.p.p., il cui testo presenta oscurità ed errori tanto più inopportuni in quanto destinati ad incidere sulla motivazione del provvedimento giudiziario.
description: Transposing Directive 2016/343/EU of 9 March 2016, the Italian legislator has issued Legislative Decree n. 188 of 8 November 2021 – entered into force on 14 December 2021 – about the implementation of various aspects of the presumption of innocence and the right to attend a criminal trial. This paper analyzes the single provisions of the new law in light of the relevant provisions of the Directive and of the case law’s development, with special regard to the European Court of Justice’s one. The final picture shows a regulation with lights and shadows. It is surely to be welcomed insofar as it calls for an accurate reflection by public authorities on the opportunities of spreading news concerning criminal proceedings, as well as – more importantly – on the way such information is disseminated, which should be such as to avoid charging suspects or defendants with an anticipated guilty plea, when a final judgment has not yet been rendered. The same does not apply to the decision to introduce the new Article 115 bis of the Code of Criminal Procedure, whose text reveals unclarity and mistakes, that are all the more inappropriate if we consider the impact they will have on the reasoning of criminal judgments.

description: Abstract. 
This study aims to deepen and analyze the implementation and effectiveness of human resource management in the context of educational institutions in schools. This study uses a qualitative method with a descriptive approach. The data collection techniques used in this study are interviews and documentation. The validity of this research is also obtained through the source triangulation technique, which compares the information obtained by the author with the theory used. Informants in this study consisted of school principals, administrative heads, and teachers. Data analysis is carried out through data reduction, data presentation, and conclusion drawing. The results of the study show that the implementation of human resource management at SDIT Asy-Syafiiyah Kabupaten Garut has been carried out well, with a focus on four aspects; recruitment, training, compensation, and termination. The four main aspects studied by the author are in line with Schuler's theory and the opinions of the three informants studied. The results of this study are expected to contribute to the development of human resourcemanagement theory and practice, and provide useful guidance for educational institutions in improving the quality and effectiveness of human resource management.

description: In this article we introduce model to describe the behavior of a multinational company (MNC) that operates transfer pricing and debt shifting, with the purpose of incrementing its value, intended as the sum of equity and debt. We compute, in a stochastic environment and under default risk, the optimal shares of profit and debt to be shifted and show how they are a effected by exogenous features of the market. In addition, by means of a numerical analysis, we simulate and quantify the benefit arising from the exploitation of tax avoidance practices and study the corresponding impact on MNC's fundamental indicators. A wide sensitivity analysis on model's parameters is also provided.

description: Very Large Array observations of the Galactic Center at 7 mm have produced an image of the 30 arcseconds surrounding Sgr A* with a resolution of 82x42 milliarcseconds (mas). A comparison with IR images taken simultaneously with the Very Large Telescope (VLT) identifies 41 radio sources with L-band (3.8 microns) stellar counterparts. The well-known young, massive stars in the central Sgr A* cluster (e.g., IRS 16C, IRS 16NE, IRS 16SE2, IRS 16NW, IRS 16SW, AF, AFNW, IRS 34W and IRS 33E) are detected with peak flux densities between 0.2 and 1.3 mJy. The origin of the stellar radio emission in the central cluster is discussed in terms of ionized stellar winds with mass-loss rates in the range 0.8-5x10^{-5} solar mass per year. Radio emission from eight massive stars is used as a tool for registration between the radio and infrared frames with mas precision within a few arcseconds of Sgr A*. This is similar to the established technique of aligning SiO masers and evolved stars except that radio stars lie within a few arcseconds of Sgr A*. Our data show a scatter of ~6.5 mas in the positions of the eight radio sources that appear in both the L-band and 7 mm images. Lastly, we use the radio and IR data to argue that members of IRS 13N are Young Stellar Objects rather than dust clumps, supporting the hypothesis that recent star formation has occurred near Sgr A*.

description: Thermal Nyquist noise fluctuations of high-$Q$ Bulk Acoustic Wave (BAW) cavities have been observed at cryogenic temperatures with a DC Superconducting Quantum Interference Device (SQUID) amplifier. High $Q$ modes with bandwidths of few tens of milliHz produce thermal fluctuations with a Signal-To-Noise ratio of up to 23dB. The estimated effective temperature from the Nyquist noise is in good agreement with the physical temperature of the device, confirming the validity of the equivalent circuit model and the non-existence of any excess resonator self-noise. The measurements also confirm that the quality factor remains extremely high ($Q>10^8$ at low order overtones) for very weak (thermal) system motion at low temperatures, when compared to values measured with relatively strong external excitation. This result represents an enabling step towards operating such a high-Q acoustic device at the standard quantum limit.

title: Using whole genome sequencing to investigate the inter-species transmission dynamics of Mycobacterium bovis
Creators: name: Crispell, Joseph
Publisher: name: University of Glasgow
Year: 2017

description: Bovine tuberculosis (bTB), a disease of cattle caused by Mycobacterium bovis, presents considerable health and economic burdens in many countries. In the United Kingdom and New Zealand, wildlife reservoirs are implicated in the spread and persistence of bTB in cattle populations. Where multi-host systems exist, understanding the roles of different host species in the spread and persistence of M. bovis infection in livestock is paramount. This thesis describes how Whole Genome Sequenced (WGS) M. bovis data can be used to investigate inter-species transmission of bTB between livestock and wildlife populations.

WGSdata must be processed before it can be used in downstream analyses. A filter sensitivity analysis was used to investigate whether the selection of quality criteria to be used in the processing of WGS data, could be informed by epidemiological data describing the sampled bTB system. WGS M. bovis data were available from three different bTB systems: in Northern Ireland, England and New Zealand. By using agreement between the genetic data, resulting from applying different quality filters, and the epidemiological data as an indication of the appropriateness of filtering, it was demonstrated that epidemiological data could inform the selection of quality criteria.

With appropriately processed WGSdata from infected cattle and wildlife in New Zealand, the role of wildlife reservoirs was investigated. In addition, the WGS data were compared to the types defined by a different molecular typing method used heavily in New Zealand until 2012. The high resolution WGS data agreed well with the previous typing method, and was used to demonstrate that inter-species transmission had occurred between the sampled cattle and wildlife populations.

The large spatial range of the data available from New Zealand made it difficult to determine the direction of inter-species transmission. In the southwest of England, Woodchester Park is home to a badger population that is naturally infected with M. bovis and living in close proximity to many cattle herds. WGS M. bovis data, for infected cattle and badgers sampled from this system, combined with detailed epidemiological data, were used to provide evidence of inter-species transmission in both directions. The sampled badger population was also shown to be acting as a maintenance reservoir for bTB.

This thesis describes how WGSdata can be used to investigate inter-species transmission, but also highlights how the underlying bTB systems must be sampled appropriately for these data to be most informative. Future work will involve addressing the limitations of the available data and the analyses conducted, as well as analysis of new data and implementation of new methods.

description: Based on the multi-point propagator expansion, we present resummed perturbative calculations for cosmological power spectra and correlation functions in the context of modified gravity. In a wide class of modified gravity models that have a screening mechanism to recover general relativity (GR) on small scales, we apply the eikonal approximation to derive the governing equation for resummed propagator that partly includes the non-perturbative effect in the high-k limit. The resultant propagator in the high-k limit contains the new corrections arising from the screening mechanism as well as the standard exponential damping. We explicitly derive the expression for new high-k contributions in specific modified gravity models, and find that in the case of f(R) gravity for a currently constrained model parameter, the corrections are basically of the sub-leading order and can be neglected. Thus, in f(R) gravity, similarly to the GR case, we can analytically construct the regularized propagator that reproduces both the resummed high-k behavior and the low-k results computed with standard perturbation theory, consistently taking account of the nonlinear modification of gravity valid at large scales. With the regularized multi-point propagators, we give predictions for power spectrum and correlation function at one-loop order, and compare those with N-body simulations in f(R) gravity model. As an important application, we also discuss the redshift-space distortions and compute the anisotropic power spectra and correlation functions.

description: In this work, we apply the adaptive discontinuous Galerkin (DGAFEM) method to the convection dominated non-linear, quasi-stationary diffusion-convection-reaction equations. We propose an efficient preconditioner using a matrix reordering scheme to solve the sparse linear systems iteratively arising from the discretized non-linear equations. Numerical examples demonstrate effectiveness of the DGAFEM to damp the spurious oscillations and resolve well the sharp layers occurring in convection dominated non-linear equations.

description: Entropic forces in colloidal suspensions and in polymer-colloid systems are of long-standing and continuing interest. Experiments show how entropic forces can be used to control the self-assembly of colloidal particles. Significant advances in colloidal synthesis made in the past two decades have enabled the preparation of high quality nano-particles with well-controlled sizes, shapes, and compositions, indicating that such particles can be utilized as "artificial atoms" to build new materials. To elucidate the effects of the shape of particles upon the magnitude of entropic interaction, we analyse the entropic interactions of two cut-spheres. We show that the solvent induces a strong directional depletion attraction among flat faces of the cut-spheres. Such an effect highlights the possibility of using the shape of particles to control directionality and strength of interaction.

description: As physical inactivity statistics for the U.S. population show an alarming trend, many health problems have been increasing among Americans in recent decades. Thus, identification of the factors that influence people’s physical activity levels and health outcomes has become ever more essential to promote public health. The built envSFironment is among the main factors that impact individuals’ health outcomes. However, little is known about the health impacts of built environment factors at large geographical scales such as those of the metropolitan area of residence. Further, the health impacts of travel behavior such as telecommuting and teleshopping remain unclear. This study uses an ecological model framework to probe the roles of travel behavior and built as well as social environments at different spatial levels in health. Instrumental variable binary probit models have been developed to examine the complex interlinks between measures of travel behavior, physical activity levels, built and social environment characteristics, and individuals’ health outcomes. Findings indicate that built and social environment factors at different spatial levels, including the metropolitan area, are correlated with individuals’ health outcomes. Additionally, the findings suggest that increased levels of telecommuting and teleshopping within communities may lead to unfavorable health outcomes. The findings shed light on the most promising policy interventions that can promote public health through modifications targeting people’s travel choices as well as the built and social environments within urban areas.

description: Designers perform early-stage formative usability tests with low-fidelity prototypes to improve the design of new products. This low-tech prototype style reduces the manufacturing resources but limits the functions that can be assessed. Recent advances in technology enable designers to create low-fidelity 3D models for users to engage in a virtual environment. Three-dimensional models communicate design concepts and are not often used in formative usability testing. The proposed method discusses how to create a virtual replica of a product by assessing key human interaction steps and addresses the limitations of translating those steps into a virtual environment. In addition, the paper will provide a framework to evaluate the usability of a product in a virtual setting, with a specific emphasis on low-resource online testing in the user population. A study was performed to pilot the subject’s experience with the proposed approach and determine how the virtual online simulation impacted the performance. The study outcomes demonstrated that subjects were able to successfully interact with the virtual replica and found the simulation realistic. This method can be followed to perform formative usability tests earlier and incorporate subject feedback into future iterations of their design, which can improve safety and product efficacy.

description: Transport of colloid particles through narrow channels is ubiquitous in cell biology as well as becoming increasingly important for microfluidic applications or targeted drug delivery. Membrane channels in cells are useful models for artificial designs because of their high efficiency, selectivity and robustness to external fluctuations. Here we model the passive channels that let cargo simply diffuse through them, affected by a potential profile along the way. Passive transporters achieve high levels of efficiency and specificity from binding interactions with the cargo inside the channel. This however leads to a paradox: why should channels which are so narrow that they are blocked by their cargo evolve to have binding regions for their cargo if that will effectively block them? Using Brownian dynamics simulations, we show that different potentials, notably symmetric, increase the flux through narrow passive channels -- and investigate how shape and depth of potentials influence the flux. We find that there exist optimal depths for certain potential shapes and that it is most efficient to apply a small force over an extended region of the channel. On the other hand, having several spatially discrete binding pockets will not alter the flux significantly. We also explore the role of many-particle effects arising from pairwise particle interactions with their neighbours and demonstrate that the relative changes in flux can be accounted for by the kinetics of the absorption reaction at the end of the channel.

description: Temperature dependent transport measurements on ultrathin antiferromagnetic Mn films reveal a heretofore unknown non-universal weak localization correction to the conductivity which extends to disorder strengths greater than 100 k$Ω$ per square. The inelastic scattering of electrons off of gapped antiferromagnetic spin waves gives rise to an inelastic scattering length which is short enough to place the system in the 3d regime. The extracted fitting parameters provide estimates of the energy gap ($Δ= 16$ K) and exchange energy ($\bar{J} = 320$ K).

description: L'articolo esamina la lezione su L'ambiguità del piacere e del gioco tenuta da Bataille a Sainte-Anne, nel 1958, su invito di Jacques Lacan, e non pubblicata prima di quarant'anni dalla sua morte. Secondo Bataille, il piacere del gioco esprime il bisogno di un renversement o di un dépassement dei limti che sono richiesti da uno stato normale, aprendo in questo modo un cammino che va nella direzione opposta del movimento della conoscenza. Sempre secondo Bataille, comunque, il piacere non è in grado di sostenere lo sforzo richiesto dal cambio di forma senza l'aiuto dell'istinto di morte, compreso come «l'estremo punto che noi possiamo raggiungere dall'instabilità». La ricerca dell'"illimitato", e dell'"indefinito", rimane un'aspirazione alla forma, comunque estrema, rappresentante se stessa nell'istante che incorpora la necessità di un cambiamento e di una metamorfosi: una trasformazione inevitabile. Questa è la sfida posta da un inconscio o "semi-inconscio" che finalmente rivela se stesso, in un eccesso, come l'impossibile.

description: There are many islands without full access to electricity around the world. These energy-poor regions generally have drinking water supply issues too. Renewable energy-powered desalination units can convert seawater to freshwater by using such as oceanic wave energy to mitigate the water limitation in small islands. A novel wave-powered floating desalination system (WavoWater) was proposed for easy on-site deployment and minimal environmental impact. WavoWater can produce freshwater using a vacuum-applied air-gap membrane distillation (AGMD) system, and the heat needed for the AGMD is provided through a heat pump powered by wave energy. Small-scale experiments were conducted to estimate the water generation rate of the vacuum-applied AGMD, and the WavoWater system modeling was developed based on the experimental results and wave data observed near the City of Newport, OR, USA. Fast Fourier transform was applied to estimate the wave energy spectrum in a random sea wave state. It was evaluated that 1 m-diameter WavoWater can produce 12.6 kg of fresh water per day with about 3.1 kWh of wave energy. With the performance evaluation, the aspects of zero discharging and minimal environmental impact were also highlighted for the stand-alone wave-powered desalination system.
