Quality of Service for High Performance IoT Systems

The fourth industrial generation brought both solutions as challenges. It allowed greater efficiency and effectiveness in manufacturing, reducing both costs and wastes. However, it consists in the deployment of innumerable devices for data collection and control processes. This brings challenges such as interoperability between all these heterogeneous systems. Thus, a group of partners, supported by the European Union, proposed a solution, the Arrowhead Framework. Its aim is to create a framework with a service-oriented architecture (SOA) enabling an abstract collaboration between all these different devices. While in development, the framework does not provide Quality of Service (QoS), which prevents its use in more demanding networks. This limitation was the central problem solved in this project. This project focus on developing an architecture that provides QoS support in Arrowhead compliant systems. Here the main challenges addressed are the following: developing an architecture capable of working with different communication protocols and technologies; develop an architecture capable of working with an unlimited number of QoS requirements. During the entire project, its development process consisted in two main iterations: the first was regarding the development of an architecture; the second consisted in the development of a pilot project based on the FTT-SE protocol that could test the architecture developed in the first iteration. At last, the final product consists in two systems, one for QoS configuration and other for monitoring. These two systems are independent of each other. Regarding QoS requirements, only delay and bandwidth were implemented.info:eu-repo/semantics/publishedVersio

A (ir)regularity-aware task scheduler for heterogeneous platforms

This paper addresses the design, implementation and validation of an e ective scheduling scheme for both regular and irregular applications on heterogeneous platforms. The scheduler uses an empirical performance model to dynamically schedule the workload, organized into a given number of chunks, and follows the Heterogeneous Earliest Finish Time (HEFT) scheduling algorithm, which ranks the tasks based on both their computation and communication costs. The evaluation of the proposed approach is based on three case studies { the SAXPY, the FFT and the Barnes-Hut algorithms { two regular and one irregular application. The scheduler was evaluated on a heterogeneous platform with one quad-core CPU-chip accelerated by one or two GPU devices, embedded in the GAMA framework. The evaluation runs measured the e ectiveness, the e ciency and the scalability of the proposed method. Results show that the proposed model was e active in addressing both regular and irregular applications, on heterogeneous platforms, while achieving ideal ( 100%) levels of e ciency in the irregular Barnes-Hut algorithm.Fundação para a Ciência e Tecnologi

Linking chemical exposure to lipid homeostasis: A municipal waste water treatment plant influent is obesogenic for zebrafish larvae

Obesity, a risk factor for the development of type-2 diabetes, hypertension, cardiovascular disease, hepatic steatosis and some cancers, has been ranked in the top 10 health risk in the world by the World Health Organization. Despite the growing body of literature evidencing an association between the obesity epidemic and specific chemical exposure across a wide range of animal taxa, very few studies assessed the effects of chemical mixtures and environmental samples on lipid homeostasis. Additionally, the mode of action of several chemicals reported to alter lipid homeostasis is still poorly understood. Aiming to fill some of these gaps, we combined an in vivo assay with the model species zebrafish (Danio rerio) to screen lipid accumulation and evaluate expression changes of key genes involved in lipid homeostasis, alongside with an in vitro transactivation assay using human and zebrafish nuclear receptors, retinoid X receptor α and peroxisome proliferator-activated receptor γ. Zebrafish larvae were exposed from 4 th day post-fertilization until the end of the experiment (day 18), to six different treatments: experimental control, solvent control, tributyltin at 100 ng/L Sn and 200 ng/L Sn (positive control), and wastewater treatment plant influent at 1.25% and 2.5%. Exposure to tributyltin and to 2.5% influent led to a significant accumulation of lipids, with white adipose tissue deposits concentrating in the perivisceral area. The highest in vitro tested influent concentration (10%) was able to significantly transactivate the human heterodimer PPARγ/RXRα, thus suggesting the presence in the influent of HsPPARγ/RXRα agonists. Our results demonstrate, for the first time, the ability of complex environmental samples from a municipal waste water treatment plant influent to induce lipid accumulation in zebrafish larvae.This work was supported by the Norte2020 and FEDER (Coral—Sustainable Ocean Exploitation—Norte-01-0145-FEDER-000036), by the Spanish Agencia Estatal de Investigación (CTM2017-84763-C3-2-R), the Galician Council of Culture, Education and Universities (ED431C2017/36) and FEDER/ERDF, and by the project NOR-WATER (0725), financed by “Programa de Cooperação Interreg Portugal/Espanha, (POCTEP) 2014-2020.

MAternal Mental Health in the WORKplace (MAMH@WORK): a protocol for promoting perinatal maternal mental health and wellbeing

© 2021 by the authors. Licensee MDPI, Basel, Switzerland. This article is an open access article distributed under the terms and conditions of the Creative Commons Attribution (CC BY) license (http://creativecommons.org/licenses/by/4.0/).Women are exposed to increased burden of mental disorders during the perinatal period: 13–19% experience postpartum depression. Perinatal psychological suffering affects early mother-child relationship, impacting child’s emotional and cognitive development. Return-to-work brings additional vulnerability given the required balance between parenting and job demands. The MAternal Mental Health in the WORKplace (MAMH@WORK) project aims to develop and evaluate the effectiveness of a brief and sustainable intervention, promoting (a) maternal mental health throughout pregnancy and first 12 months after delivery, and (b) quality of mother–child interactions, child emotional self-regulation, and cognitive self-control, while (c) reducing perinatal absenteeism and presenteeism. MAMH@WORK is a three-arm randomized controlled trial. A short-term cognitive-behavioral therapy-based (CBT-based) psychoeducation plus biofeedback intervention will be implemented by psychiatrists and psychologists, following a standardized procedure manual developed after consensus (Delphi method). Participants (n = 225, primiparous, singleton pregnant women at 28–30 weeks gestational age, aged 18–40 years, employed) will be randomly allocated to arms: CBT-based psychoeducation intervention (including mindfulness); psychoeducation plus biofeedback intervention; and control. Assessments will take place before and after delivery. Main outcomes (and main tools): mental health literacy (MHLS), psychological wellbeing (HADS, EPDS, KBS, CD-RISC, BRIEF COPE), quality of mother–child interaction, child–mother attachment, child emotional self-regulation and cognitive self-control (including PBQ, Strange Situation Procedure, QDIBRB, SGS-II, CARE-Index), job engagement (UWES), and presenteeism. Intention-to-treat and per-protocol analyses will be conducted; Cohen’s d coefficient, Cramer’s V and odds ratio will be used to assess the effect size of the intervention. MAMH@WORK is expected to contribute to mental health promotion during the perinatal period and beyond. Its results have the potential to inform health policies regarding work–life balance and maternal mental health and wellbeing promotion in the workplace.The development of this protocol has benefited from the funding from FCT, under the grants UIDB/04295/2020 and UIDP/04295/2020.info:eu-repo/semantics/publishedVersio

Morphological and nutritional evaluation of ‘caraíba’ seedlings in different substrates using domestic sewage effluent for fertirrigation

In this study, we evaluated the effects of fertigation with domestic sewage effluent and different substrates on the growth of Caraíba seedlings (Tabebuia aurea Benth). The experiment was accomplished in a greenhouse in Mossoró, RN. Five irrigation solutions (100% of water supply - WS, 100% of domestic sewage effluent – DS and dilutions of 75% DS + 25% WS, 50% DS + 50% WS e 25% DS + 75% WS) were tested and two substrates (75% soil + 25% bovine manure and 75% soil + 25% coconut fiber) using completely randomized design in subdivided plots with three replicates per treatment. Growth and development parameters were measured at 30, 60, 90, and 150 days after cultivation. The variables shoots height, collar diameter, height/diameter ratio, dry matter of root, shoots and total (root and shoots), shoots/root ratio, Dickson quality index, and nutritional evaluation of nitrogen, phosphorus, potassium and calcium were determinate. We verified that the use of domestic sewage increased growth and quality of caraíba seedlings, besides promoting nutrient accumulation in the plants grown in substrate of bovine manure plus soil with 100% application of domestic sewage in the fertigationEn este estudio se objetivó evaluar los efectos del agua de fertirrigación con efluente de alcantarillado doméstico y de diferentes sustratos de cultivo en el crecimiento de mudas de Caraíba (Tabebuia aurea Benth). El experimento fue realizado en condiciones de ambiente protegido en la ciudad de Mossoró, RN. Se han probado cinco soluciones de riego (100% de agua de abastecimiento - AA, 100% de efluente de desagüe doméstico - EE y las diluciones del 75% EE + 25% AA, 50% EE + 50% AA y 25% EE + 75 (% AA) y dos sustratos (75% suelo + 25% estiércol de bovinos y 75% suelo + 25% fibra de coco) utilizando el delineamiento estadístico completamente casualizado, arregladas en parcelas subdivididas con tres repeticiones por tratamiento. Las evaluaciones de crecimiento y desarrollo se realizaron a los 30, 60, 90 y 150 días después de la siembra. Se determinaron las variables altura de la parte aérea, diámetro del cuello, relación entre altura y diámetro, materias secas del sistema radicular, de la parte aérea y total (raíz y parte aérea), relación entre raíz y parte aérea, índice de Dickson, y la evaluación nutricional de nitrógeno, fósforo, potasio y calcio. Se verificó que la utilización de efluente doméstico aumentó el crecimiento y la calidad de las mudas de caraíba, además de promover la acumulación nutricional en las plantas cultivadas en sustrato de estiércol bovino más suelo cuando se fertirrigadas con 100% de efluente doméstic

MAMMALS IN PORTUGAL : A data set of terrestrial, volant, and marine mammal occurrences in P ortugal

Mammals are threatened worldwide, with 26% of all species being includedin the IUCN threatened categories. This overall pattern is primarily associatedwith habitat loss or degradation, and human persecution for terrestrial mam-mals, and pollution, open net fishing, climate change, and prey depletion formarine mammals. Mammals play a key role in maintaining ecosystems func-tionality and resilience, and therefore information on their distribution is cru-cial to delineate and support conservation actions. MAMMALS INPORTUGAL is a publicly available data set compiling unpublishedgeoreferenced occurrence records of 92 terrestrial, volant, and marine mam-mals in mainland Portugal and archipelagos of the Azores and Madeira thatincludes 105,026 data entries between 1873 and 2021 (72% of the data occur-ring in 2000 and 2021). The methods used to collect the data were: live obser-vations/captures (43%), sign surveys (35%), camera trapping (16%),bioacoustics surveys (4%) and radiotracking, and inquiries that represent lessthan 1% of the records. The data set includes 13 types of records: (1) burrowsjsoil moundsjtunnel, (2) capture, (3) colony, (4) dead animaljhairjskullsjjaws, (5) genetic confirmation, (6) inquiries, (7) observation of live animal (8),observation in shelters, (9) photo trappingjvideo, (10) predators dietjpelletsjpine cones/nuts, (11) scatjtrackjditch, (12) telemetry and (13) vocalizationjecholocation. The spatial uncertainty of most records ranges between 0 and100 m (76%). Rodentia (n=31,573) has the highest number of records followedby Chiroptera (n=18,857), Carnivora (n=18,594), Lagomorpha (n=17,496),Cetartiodactyla (n=11,568) and Eulipotyphla (n=7008). The data setincludes records of species classified by the IUCN as threatened(e.g.,Oryctolagus cuniculus[n=12,159],Monachus monachus[n=1,512],andLynx pardinus[n=197]). We believe that this data set may stimulate thepublication of other European countries data sets that would certainly contrib-ute to ecology and conservation-related research, and therefore assisting onthe development of more accurate and tailored conservation managementstrategies for each species.
