Preventive Conservation: a Key Method to Ensure Cultural Heritage’s Authenticity and Integrity in Preservation Process
2012
This article studies the role of preventive conservation in cultural heritage preservation. It shows through cultural heritage theory and conservation professions development process how important part preventive conservation has had and still has in cultural heritage preservation and damage prevention. Preventive conservation is a multidisciplinary orientation that uses indirect measures and actions to avoid or to minimize future deterioration or loss of cultural heritage. Conservation professionals should recognize its importance as the most effective method in promoting the long-term preservation of cultural heritage. Therefore, preventive conservation should be the basic theoretical per…
Performance of the dentogingival junction with mta and biodentine on the treatment of invasive cervical resorptions. A literature review and case rep…
2021
Invasive cervical resorption (ICR) is an uncommon phenomenon (0.1%), however, it represents a challenge to the structural and functional integrity of the dentogingival junction, as well as a risk for the survival of the affected tooth. They are characterized by their location and invasive character, being able to appear in any tooth of the permanent dentition. It shows up after the damage to the cervical insertion apparatus, leaving the pulp without participation in the origin of the lesion. They may appear just below the junctional epithelium or at a more apical level. The MTA® (Dentsply, Tulsa dental, Tulsa OK) and the Biodentine® (Septodent, Saint Maur of Fossés, France) are two biomater…
Basic Concepts of Power Distribution Network Design for High-Speed Transmission
2011
This paper tries to gather the Power Distribution Network (PDN) techniques used to preserve power integrity in PCB designs when transmitting data rates over 6 Gbps using the newest commercial optical modules. The PDN design described allows for proper impedance control of the power supply with the appropriate choice of the number, location and values of capacitors. This method needs the knowledge of the electrical RLC model of the regulators, copper planes, capacitors and vias used in the PCB. A particular case of PDN design will be presented for a module using one SNAP12 optical transmitter and one receiver connected to an Altera Stratix II GX FPGA. This board is designed to work with data…
The Impact of Age on the Association Between Physical Activity and White Matter Integrity in Cognitively Healthy Older Adults
2020
Cognition emerges from coordinated processing among distributed cortical brain regions, enabled through interconnected white matter networks. Cortical disconnection caused by age-related decline in white matter integrity (WMI) is likely to contribute to age-related cognitive decline. Physical activity (PA) has been suggested to have beneficial effects on white matter structure. However, its potential to counteract age-related decline in WMI is not yet well established. The present explorative study analyzed if PA was associated with WMI in cognitively healthy older adults and if this association was modulated by age. Forty-four cognitively healthy older individuals (aged 60–88 years) with d…
Communication-Efficient Federated Learning in Channel Constrained Internet of Things
2022
Federated learning (FL) is able to utilize the computing capability and maintain the privacy of the end devices by collecting and aggregating the locally trained learning model parameters while keeping the local personal data. As the most widely-used FL framework,Jederated averaging (FedAvg) suffers an expensive communication cost especially when there are large amounts of devices involving the FL process. Moreover, when considering asynchronous FL, the slowest device becomes the bottleneck for the cask effect and determines the overall latency. In this work, we propose a communication-efficient federated learning framework with partial model aggregation (CE-FedPA) algorithm to utilize comp…
University Faculty Perception of Cyber-Plagiarism: A Virtual Discussion Group
2021
Resumen Este estudio analiza el ciberplagio académico desde la perspectiva del profesorado del Grado en Traducción e Interpretación de la Universidad Internacional de Valencia. Dado que se trata de una práctica fraudulenta cada vez más extendida en las aulas universitarias, se hace necesario que el cuerpo docente reflexione sobre ella para evitar que se convierta en un recurso estructural por parte del alumnado en este nivel educativo. El estudio apuesta por una metodología cualitativa y, en concreto, el grupo de discusión, el cual se lleva a cabo por videoconferencia gracias a la participación de su claustro (n=16). Como instrumento se diseña un guion de seis preguntas a partir de las cual…
Fibre break failure processes in unidirectional composites: evaluation of critical damage states
2016
Earlier work which successfully modelled the kinetics of fibre breakage in unidirectional composites under monotonic tensile loading has been extended to quantify the kinetics of fibre failure during both monotonic and sustained tensile loading. In both cases, failure was seen to occur when a critical density of large clusters (more than 16 fibres are broken within the representative volume element) of fibre breaks developed. However, in monotonic loading failure occurred very quickly after the first development of these large clusters, whereas under sustained loading the composite could accommodate greater levels of large clusters because of the lower applied load. This article is part of …
Assessment of cross-flow filtration as microalgae harvesting technique prior to anaerobic digestion: Evaluation of biomass integrity and energy demand
2018
[EN] In the present study, the effect of cross-flow filtration (CFF) on the overall valorization of Chlorella spp. microalgae as biogas was assessed. The effect of CFF on microalgae cell integrity was quantified in terms of viability which was correlated with the anaerobic biodegradability. The viability dropped as the biomass concentration increased, whereas anaerobic biodegradability increased linearly with the viability reduction. It was hypothesized that a stress-induced release and further accumulation of organic polymers during CFF increased the flux resistance which promoted harsher shear-stress conditions. Furthermore, the volume reduction as the concentration increased entailed an …
Response of macrophyte communities and status metrics to natural gradients and land use in boreal lakes
2012
Abstract We studied the relations of aquatic macrophyte communities, ecological quality metrics and water quality to lake characteristics and to land use defined at multiple spatial scales (three lake marginal zones (LMZs) of contrasting width and the whole topographic catchment) in 110 boreal lakes in Finland using ordination and generalised additive modelling. Variation in macrophyte community composition of our lakes was related to water quality, land use, latitude and lake morphology. Relationships of macrophyte status metrics – the proportion of type-specific species (TT50), Percent Model Affinity (PMA) and Trophic Index (TI) – to land use were scale dependent. The proportion of agricu…
Hypervisor-assisted Atomic Memory Acquisition in Modern Systems
2019
Reliable memory acquisition is essential to forensic analysis of a cyber-crime. Various methods of memory acquisition have been proposed, ranging from tools based on a dedicated hardware to software only solutions. Recently, a hypervisor-based method for memory acquisition was proposed (Qi et al., 2017; Martignoni et al., 2010). This method obtains a reliable (atomic) memory image of a running system. The method achieves this by making all memory pages non-writable until they are copied to the memory image, thus preventing uncontrolled modification of these pages. Unfortunately, the proposed method has two deficiencies: (1) the method does not support multiprocessing and (2) the method does…
