Lähiliikennejunien huoltokierrätyksen tietojärjestelmän määrittely

Tämä työ perustuu järjestelmämäärittelyyn, joka tehtiin osana laajempaa kehityshanketta. Määrittelyssä pitäydyttiin olemassa olevissa toimintatavoissa, joten järjestelmällä ei ole vaikutusta toiminnanohjauksen periaatteisiin. Järjestelmän toiminnallisuus on määritelty asetettujen vaatimusten pohjalta, jotka on johdettu kunnossapitotoiminnan ongelmista. Määrittelyssä kuvatulla järjestelmällä voidaan tukea lähiliikennejunien huoltokierrätystä ja kunnossapitotoiminnan ohjausta. Tässä työssä käsitellään järjestelmän toiminnallisuutta ja vaikutuksia lähiliikennejunien kunnossapitotoimintaan. Olennainen järjestelmän piirre on, että järjestelmä ei suoranaisesti vaikuta kunnossapitotoiminnan tehokkuuteen vaan ainoastaan tuottaa tiedon jota työnjohtajat tarvitsevat suunnitellessaan junayksikköjen kierrätystä. Järjestelmällä saatavat hyödyt siis riippuvat siitä, kuinka hyvin tietoa osataan toiminnanohjauksessa hyödyntää.

Tren d’alta velocitat i desenvolupament local urbà. Aportacions a una nova base teòrica

Una de les finalitats principals del tren d’alta velocitat és la d’aportar desenvolupament local en aquelles ciutats i territoris on se’n construeixi una estació. Per aquesta raó, calen reflexions teòriques que ajudin els agents i les institucions a planificar correctament l’arribada de la nova gran infraestructura de transport, especialment en els aspectes relacionats amb la capacitat d’organització dels actors territorials. La teoria reticular pot ser una base teòrica útil per evitar concepcions deterministes de la relació entre infraestructura i territori, per explicar com es produeix el procés de desenvolupament local i per demostrar la importància dels agents territorials en aquest procés

Recoupled separated-local-field experiments and applications to study intermediate-regime molecular motions

A specific separated-local-field NMR experiment, dubbed Dipolar-Chemical-Shift Correlation (DIPSHIFT) is frequently used to study molecular motions by probing reorientations through the changes in XH dipolar coupling and T-2. In systems where the coupling is weak or the reorientation angle is small, a recoupled variant of the DIPSHIFT experiment is applied, where the effective dipolar coupling is amplified by a REDOR-like pi-pulse train. However, a previously described constant-time variant of this experiment is not sensitive to the motion-induced T-2 effect, which precludes the observation of motions over a large range of rates ranging from hundreds of Hz to around a MHz. We present a DIPSHIFT implementation which amplifies the dipolar couplings and is still sensitive to T-2 effects. Spin dynamics simulations, analytical calculations and experiments demonstrate the sensitivity of the technique to molecular motions, and suggest the best experimental conditions to avoid imperfections. Furthermore, an in-depth theoretical analysis of the interplay of REDOR-like recoupling and proton decoupling based on Average-Hamiltonian Theory was performed, which allowed explaining the origin of many artifacts found in literature data.

Dynamics of a local Alpine flooding event in October 2011: moisture source and large-scale circulation

Alpine heavy precipitation events often affect small catchments, although the circulation pattern leading to the event extends over the entire North Atlantic. The various scale interactions involved are particularly challenging for the numerical weather prediction of such events. Unlike previous studies focusing on the southern Alps, here a comprehensive study of a heavy precipitation event in the northern Alps in October 2011 is presented with particular focus on the role of the large-scale circulation in the North Atlantic/European region. During the event exceptionally high amounts of total precipitable water occurred in and north of the Alps. This moisture was initially transported along the flanks of a blocking ridge over the North Atlantic. Subsequently, strong and persistent northerly flow established at the upstream flank of a trough over Europe and steered the moisture towards the northern Alps. Lagrangian diagnostics reveal that a large fraction of the moisture emerged from the West African coast where a subtropical upper-level cut-off low served as an important moisture collector. Wave activity flux diagnostics show that the ridge was initiated as part of a low-frequency, large-scale Rossby wave train while convergence of fast transients helped to amplify it locally in the North Atlantic. A novel diagnostic for advective potential vorticity tendencies sheds more light on this amplification and further emphasizes the role of the ridge in amplifying the trough over Europe. Operational forecasts misrepresented the amplitude and orientation of this trough. For the first time, this study documents an important pathway for northern Alpine flooding, in which the interaction of synoptic-scale to large-scale weather systems and of long-range moisture transport from the Tropics are dominant. Moreover, the trapping of moisture in a subtropical cut-off near the West African coast is found to be a crucial precursor to the observed European high-impact weather.

La institucionalización del enfoque de género en las políticas públicas a nivel del desarrollo local

Al proponer este tema estamos tratando de realizar un análisis de los principales aspectos teóricos que se han debatido, tanto a nivel de la sociedad, como de la Academia y del Estado, a lo largo del proceso de incorporación de la temática de las mujeres en las Políticas Públicas. Se busca establecer una relación entre los postulados teóricos propuestos desde diferentes fuentes (Organismos Internacionales, Organizaciones Feministas, Movimientos de Mujeres, Foros de Mujer y Desarrollo de Mercociudes, etc.) y su efectiva incorporación en las Políticas Públicas llevadas adelante en la Argentina, en el ámbito nacional, provincial y municipal. También investigamos, analizamos y evaluamos las Políticas Públicas dirigidas a las mujeres en los últimos cinco años en algunos municipios. Así mismo desarrollamos, justificamos y promovemos la necesidad de Institucionalizar el Enfoque de Género en todos los niveles de gobierno, fundamentalmente, a nivel de las competencias de las instituciones que tienen que ver con el desarrollo local. Para este caso y en general, para los países latinoamericanos, la unidad de análisis la constituye el Municipio, que está directamente relacionado con los problemas administrativos y de planificación de políticas públicas orientadas a dicho nivel. Simultáneamente se determinan las fortalezas, los aspectos que favorecen, como las debilidades, los aspectos que obstaculizan, el proceso de institucionalización del género. En ese mismo sentido se desarrollan tareas de capacitación en Género para todos los involucrados en el proceso de investigación-acción.

Depth-based face recognition using local quantized patterns adapted for range data

A depth-based face recognition algorithm specially adapted to high range resolution data acquired by the new Microsoft Kinect 2 sensor is presented. A novel descriptor called Depth Local Quantized Pattern descriptor has been designed to make use of the extended range resolution of the new sensor. This descriptor is a substantial modification of the popular Local Binary Pattern algorithm. One of the main contributions is the introduction of a quantification step, increasing its capacity to distinguish different depth patterns. The proposed descriptor has been used to train and test a Support Vector Machine classifier, which has proven to be able to accurately recognize different people faces from a wide range of poses. In addition, a new depth-based face database acquired by the new Kinect 2 sensor have been created and made public to evaluate the proposed face recognition system.

Dynamical local models for segmentation and prediction of financial time series

In the analysis and prediction of many real-world time series, the assumption of stationarity is not valid. A special form of non-stationarity, where the underlying generator switches between (approximately) stationary regimes, seems particularly appropriate for financial markets. We introduce a new model which combines a dynamic switching (controlled by a hidden Markov model) and a non-linear dynamical system. We show how to train this hybrid model in a maximum likelihood approach and evaluate its performance on both synthetic and financial data.

Portofino Seaweed Garden: a local citizen science case study on Ericaria amentacea (C.Agardh) Molinari & Guiry, 2020 restoration

Ericaria amentacea is an endemic alga of the Mediterranean Sea that lives in the littoral rocky fringe. The species is sensitive to environmental changes, so it’s used to assess the water ecological quality. Nevertheless, E. amentacea is deeply impacted by coastal development which cause rapid regression despite data on its distribution and healthy status are still limited. Moreover, it’s little known by people outside the scientific community. In this context, Portofino Seaweed Garden was born, a conservation and citizen science project aim to involve marine outdoor enthusiasts in protecting and restoring E. amentacea, creating a submerged garden. Restoration measures have been encouraged by EU regulations. Here, using citizen science, 1) I evaluated the spatial variability of E. amentacea abundance along the central-eastern Ligurian coast, to evaluate its status and choose donor and restoration sites. 2) I carried out an E. amentacea restoration (with outplanting lab-cultured embryos on 50 clay tiles). 3) I assessed the community involvement and education of volunteers. Simple protocol was created to train them on the monitoring. Unprecedented E. amentacea reproductive mismatch affected the restoration performance, probably caused by marine heat wave that hit the Mediterranean in summer 2022. After fertile apices collection in Pontetto (GE) and during laboratory phase, gametes spawned on the discs didn’t settle as expected. Only 16 tiles showed juveniles and they were outplanted at Punta Castello (C zone of Portofino MPA). Unfortunately, they didn’t survive in the field due to an interplay of physical and biological factors. From citizen science point of view, the project demonstrated positive outcomes of collaborations between people and scientists by involving more than 100 participants. Citizen scientists became specialize in the protocol providing quality data for E. amentacea conservation. Current results suggest that outplanting should be further tested.

Gonadal Hormones Modulate The Responsiveness To Local β-blocker-induced Antinociception In The Temporomandibular Joint Of Male And Female Rats.

We have previously demonstrated that blockade of β-adrenoreceptors (β-AR) located in the temporomandibular joint (TMJ) of rats suppresses formalin-induced TMJ nociceptive behaviour in both male and female rats, but female rats are more responsive. In this study, we investigated whether gonadal hormones modulate the responsiveness to local β-blocker-induced antinociception in the TMJ of rats. Co-administration of each of the selective β1 (atenolol), β2 (ICI 118.551) and β3 (SR59230A)-AR antagonists with equi-nociceptive concentrations of formalin in the TMJ of intact, gonadectomized and hormone-treated gonadectomized male and female rats. Atenolol, ICI 118.551 and SR59230A significantly reduced formalin-induced TMJ nociception in a dose response fashion in all groups tested. However, a lower dose of each β-AR antagonist was sufficient to significantly reduce nociceptive responses in gonadectomized but not in intact and testosterone-treated gonadectomized male rats. In the female groups, a lower dose of β1 -AR antagonist was sufficient to significantly reduce nociceptive responses in gonadectomized but not in intact or gonadectomized rats treated with progesterone or a high dose of oestradiol; a lower dose of β2 -AR antagonist was sufficient to significantly reduce nociceptive responses in gonadectomized but not in intact and gonadectomized rats treated with low or high dose of oestradiol. Gonadal hormones may reduce the responsiveness to local β-blocker-induced antinociception in the TMJ of male and female rats. However, their effect depends upon their plasma level, the subtype of β-AR and the dose of β-blockers used.

Bay 41-2272 Activates Host Defence Against Local And Disseminated Candida Albicans Infections.

In our previous study, we have found that 5-cyclopropyl-2-[1-(2-fluoro-benzyl)-1H-pyrazolo[3,4-b]pyridine-3-yl]-pyrimidin-4-ylamine (BAY 41-2272), a guanylate cyclase agonist, activates human monocytes and the THP-1 cell line to produce the superoxide anion, increasing in vitro microbicidal activity, suggesting that this drug can be used to modulate immune functioning in primary immunodeficiency patients. In the present work, we investigated the potential of the in vivo administration of BAY 41-2272 for the treatment of Candida albicans and Staphylococcus aureus infections introduced via intraperitoneal and subcutaneous inoculation. We found that intraperitoneal treatment with BAY 41-2272 markedly increased macrophage-dependent cell influx to the peritoneum in addition to macrophage functions, such as spreading, zymosan particle phagocytosis and nitric oxide and phorbol myristate acetate-stimulated hydrogen peroxide production. Treatment with BAY 41-2272 was highly effective in reducing the death rate due to intraperitoneal inoculation of C. albicans, but not S. aureus. However, we found that in vitro stimulation of peritoneal macrophages with BAY 41-2272 markedly increased microbicidal activities against both pathogens. Our results show that the prevention of death by the treatment of C. albicans-infected mice with BAY 41-2272 might occur primarily by the modulation of the host immune response through macrophage activation.

Influência do transporte e mudança de local de manejo nas variáveis fisiológicas e produtivas de cabras Alpinas

Estudaram-se o efeito do transporte e a mudança de local de manejo sobre a produção e a composição do leite e sobre as variáveis fisiológicas, utilizando-se 12 cabras da raça Alpina em final de lactação. Semanalmente, foram mensuradas a produção e composição do leite e a contagem de células somáticas, além do volume do leite residual após administração de ocitocina. Foram colhidas amostras de sangue para dosagem hormonal (cortisol) e enzimática (glicose) no plasma no dia do transporte: antes (7h10min) e após (8h20min, 8h30min e 10h30min) o transporte. Nas três semanas subsequentes ao transporte, também foram colhidas amostras de sangue às 8h20min. Obtiveram-se teores mais elevados (P<0,05) de cortisol e glicose após o transporte e a mudança de local de manejo, e menor produção de leite (P<0,05) um dia após o evento. Porcentagem de gordura (P<0,05) e contagem de células somáticas apresentaram diferenças significativas (P<0,05) após o transporte. Os resultados permitem concluir que o transporte é um agente estressor que pode, momentaneamente, influenciar a produção animal.

Keratoconus prediction using a finite element model of the cornea with local biomechanical properties

PURPOSE: The ability to predict and understand which biomechanical properties of the cornea are responsible for the stability or progression of keratoconus may be an important clinical and surgical tool for the eye-care professional. We have developed a finite element model of the cornea, that tries to predicts keratoconus-like behavior and its evolution based on material properties of the corneal tissue. METHODS: Corneal material properties were modeled using bibliographic data and corneal topography was based on literature values from a schematic eye model. Commercial software was used to simulate mechanical and surface properties when the cornea was subject to different local parameters, such as elasticity. RESULTS: The simulation has shown that, depending on the corneal initial surface shape, changes in local material properties and also different intraocular pressures values induce a localized protuberance and increase in curvature when compared to the remaining portion of the cornea. CONCLUSIONS: This technique provides a quantitative and accurate approach to the problem of understanding the biomechanical nature of keratoconus. The implemented model has shown that changes in local material properties of the cornea and intraocular pressure are intrinsically related to keratoconus pathology and its shape/curvature.
