Evaluation of biocidal potential of some plant species from the Mediterranean wild flora
Lesioni cutanee stellate e simmetriche in un gemello “rimasto solo”
2021
The incidence of multiple pregnancy has increased, particularly because of the advances in assisted reproductive technologies. Multiple gestations are high risk pregnancies, especially the monochorionic ones. Two/thirds of initially twin pregnancies result in singles at birth, a condition defined as vanishing twin syndrome. The intrauterine death of one of the twins can cause direct fetal damage to the surviving one on several levels. The paper describes the case of a child born from twin pregnancy that was interrupted for one of the co-twins at early second trimester of gestation who presented with aplasia cutis congenita.
Learn to Cache: Machine Learning for Network Edge Caching in the Big Data Era
2018
The unprecedented growth of wireless data traffic not only challenges the design and evolution of the wireless network architecture, but also brings about profound opportunities to drive and improve future networks. Meanwhile, the evolution of communications and computing technologies can make the network edge, such as BSs or UEs, become intelligent and rich in terms of computing and communications capabilities, which intuitively enables big data analytics at the network edge. In this article, we propose to explore big data analytics to advance edge caching capability, which is considered as a promising approach to improve network efficiency and alleviate the high demand for the radio resou…
Underwater Multirobot Cooperative Intervention MAC Protocol
2020
This work introduces a Medium Access Control (MAC) protocol designed to allow a group of underwater robots that share a wireless communication channel to effectively communicate with each other. The goal of the Underwater Multirobot Cooperative Intervention MAC (UMCI-MAC) protocol presented in this work is to minimize the end to end delay and the jitter. The access to the medium in UMCI-MAC follows a Time Division Multiple Access (TDMA) strategy which is arbitrated by a master, which also has the capability to prioritize the transmission of some nodes over the rest of the network. Two experiments have been carried out with a team of four Autonomous Underwater Vehicles (AUV) in order to comp…
Numerical analysis of the mechanical response of wood glulam beams reinforced through the thickness by FRP rods
2009
The modern use of through-thickness reinforcement in wood glulam (glued laminated) beams, bridging the potential delamination crack faces, has shown to be an effective technological solution to improve their interlaminar fracture strength. In this paper, the behaviour of wood glulam beams is investigated from an experimental and numerical point of view, comparing the mechanical response of unreinforced and reinforced (by FRP rods) beams subjected to four points bending tests. For the numerical analysis, a simple two-phases (joint and reinforcement) interface model has been formulated and implemented in a finite element code. In particular, the classical interface model for adhesive joint, a…
Differential effects of workaholism and work engagement on the interference between life and work domains
2018
This study analyzed the differences between workaholism and work engagement in relation to their influence on work–life interference. Workaholism is an addiction to work, characterized by obsessive attitude towards job, whereas work engagement concerns a positive pattern of thoughts and feelings about one’s job; these two constructs thus represent pathological and healthy forms of heavy work investment, respectively. As a consequence, it was expected that workaholism and work engagement would have different effects on perceived interference between work and life domains. We assessed levels of workaholism, work engagement, work-to-life interference, and life-to-work interference in a sample …
Working-Time Regimes and Work-Life Balance in Europe
2015
The organization of times and places of work are key elements of working conditions, and define employees’ possibilities for balancing work and other life spheres. This study analyses several aspects of temporal and spatial flexibility, and their associations with employees’ work-life balance. This study separates four dimensions of temporal flexibility and one indicator of spatial flexibility. The dimensions of temporal flexibility are the number of hours worked, when the hours are worked, work-time intensity, and the degree of working-time autonomy. The workplace flexibility indicator is an index of work locations. Work-life balance is analysed with work-hour fit. The analyses were based …

Photocatalytic nano-composite architectural lime mortar for degradation of urban pollutants under solar and visible (interior) light
2017
Abstract Recent advances in nano-technology and nano-additives can give enhanced properties to natural hydraulic lime (NHL), creating a multifunctional material. We have prepared a novel nanocomposite, made of a commercial mortar with 1 wt% and 5 wt% added titania nanoparticles (NPs). These TiO 2 NPs are themselves doped with 1 mol% silver, to give the material enhanced photocatalytic and antimicrobial properties. The Ag-doped TiO 2 NPs were made from a simple, costs effective, aqueous green nanosynthesis process, and the end material only contains 0.01–0.05% Ag. As this mortar is intended to both combat atmospheric pollution, and create more durable/lower maintenance building facades (plas…
Neiromediatora serotonīna ietekme uz augļu mušu (Drosophila melanogaster) kustību lateralitāti
2022
Augļu mušu (Drosophila melanogaster) depresīvā uzvedības modeļa izpēte ar y-tipa labirinta metodi, var palīdzēt saprast depresīvās uzvedības pamatelementus. Augļu mušas ir labi pazīstams un plaši pielietojams modeļobjekts bioloģijas nozares pētījumos, ir zināms, ka serotonīna sintēzes cikls ir evolucionāri konservatīvs, līdzīgs visiem dzīvniekiem, tāpēc ir svarīgi apzināties kādus ķīmiskos līdzekļus vislabāk pielietot tālakos uzvedības pētījumos. Darba mērķis ir izpētīt vai selektīvie serotonīna inhibitori ietekmē augļu mušu Oregon R kustību lateritāti. Kopā pētījumā analizēti, selektīvā serototonīna atpakaļpiesaistes inhibitora escitaloprāma un, vielas ar antidepresīvām īpašībām, triptofān…
