Building Automation and Control Systems and Electrical Distribution Grids: A Study on the Effects of Loads Control Logics on Power Losses and Peaks
2018
Growing home comfort is causing increasing energy consumption in residential buildings and a consequent stress in urban medium and low voltage distribution networks. Therefore, distribution system operators are obliged to manage problems related to the reliability of the electricity system and, above all, they must consider investments for enhancing the electrical infrastructure. The purpose of this paper is to assess how the reduction of building electricity consumption and the modification of the building load profile, due to load automation, combined with suitable load control programs, can improve network reliability and distribution efficiency. This paper proposes an extensive study on…
A Simple Operating Strategy of Small-Scale Battery Energy Storages for Energy Arbitrage under Dynamic Pricing Tariffs
2015
Price arbitrage involves taking advantage of an electricity price difference, storing electricity during low-prices times, and selling it back to the grid during high-prices periods. This strategy can be exploited by customers in presence of dynamic pricing schemes, such as hourly electricity prices, where the customer electricity cost may vary at any hour of day, and power consumption can be managed in a more flexible and economical manner, taking advantage of the price differential. Instead of modifying their energy consumption, customers can install storage systems to reduce their electricity bill, shifting the energy consumption from on-peak to off-peak hours. This paper develops a deta…
Teacher coping profiles in relation to teacher well-being : a mixed method approach
2021
The aim was to investigate teachers’ coping profiles and their relations to teacher well-being. Questionnaire data was collected from 107 Finnish teachers. Theory-driven content analysis of teachers’ responses revealed three coping categories: problem-focused, emotion-focused and mixed problem- and emotion-focused. Next, teachers were categorized into four coping profiles by using latent profile analysis: Low-coping users (21%), Problem-focused-coping users (15%), High-coping users (12%) and Emotion-focused-coping users (52%). Low-coping-user teachers reported less stress and fewer depressive symptoms and sleep problems compared to Emotion-focused-coping users. Using a compact amount of cop…
Identifying Coping Profiles and Profile Differences in Role Engagement and Subjective Well-Being
2014
Coping strategies are not necessarily mutually exclusive and can be used simultaneously, a fact which has rarely been examined in coping research. We examined what kinds of coping profiles could be found in data concerning Finnish health care and service employees (n = 2756). We also studied whether role engagement (family-to-work-enrichment, work-to-family-enrichment, emotional energy at work, and work engagement) and subjective well-being (life, parental, and marital satisfaction, and psychological distress) differ between coping profiles. The data were analyzed through latent profile (LPA) and covariance analyses (Ancovas). LPA revealed seven distinct coping profiles: two active groups,…
Epigenetic profile of developmentally important genes in bovine oocytes
2011
Assisted reproductive technologies are associated with an increased incidence of epigenetic aberrations, specifically in imprinted genes. Here, we used the bovine oocyte as a model to determine putative epigenetic mutations at three imprinted gene loci caused by the type of maturation, either in vitro maturation (IVM) in Tissue Culture Medium 199 (TCM) or modified synthetic oviduct fluid (mSOF) medium, or in vivo maturation. We applied a limiting dilution approach and direct bisulfite sequencing to analyze the methylation profiles of individual alleles (DNA molecules) for H19/IGF2, PEG3, and SNRPN, which are each associated with imprinting defects in humans and/or the mouse model, and are k…
Kriminālās domāšanas profila aptaujas sākotnējā adaptācija Latvijā
2019
Pētījuma mērķis bija veikt pirmo adaptācijas posmu Latvijā Kriminālās domāšanas profila aptauju (Criminal Thninking Profile (CTP), Mitchell & Tafrate, 2011) un veikt tās ticamības un validitātes pārbaudi. Kriminālā domāšana ir izziņas process, kas balstās uz kriminālu dzīvesveidu (Walters & White, 1989, kā minēts Tafrate & Mitchell, 2014). Kriminālā domāšana ir atslēga kriminogēnajās vajadzībās, kas balstās uz psihiskajiem traucējumiem, kuri kalpo priekš racionalizācijas ,un iezīmējot aprises noziedzīgai uzvedībai un, kas var paredzēt atkārtotu likumpārkāpumu (Tangney, Mashek, & Stuewig, 2007; Walters, 2012, kā minēts Tangney, Dobbins, Stuewig & Schrader, 2017). Pētījumā tika izvirzīts jaut…
Development of School and Sport Burnout in Adolescent Student-Athletes: A Longitudinal Mixed-Methods Study.
2018
We investigated the development of school and sport burnout in adolescent student-athletes (N Time 1 = 391, N Time 2 = 373) during their first year in upper secondary school using an embedded mixed-methods design. The questionnaire-based data were analyzed with growth mixture modeling and four burnout profiles were identified among student-athletes. From the found burnout profiles, two were typical for the interviewed subsample of elite athletes (n = 17), that is, burnout risk and non risk profiles. We generated rich descriptions of well-being and ill-being, showing that elite athletes in two burnout profiles differed in their experienced demands and resources related to individual and envi…
Elites and Culture: Social Profiles in the Cultivated Population
2021
Since the 1990s, the central references of the sociology of cultural practices have been the theoretical frameworks developed by Pierre Bourdieu and Richard A. Peterson around the concepts of distinction and omnivorousness. This article is based on these frameworks; it revises them together with those of Donnat and Lahire and postulates that the terms of cultural classification and especially those of the upper classes (distinguished and omnivorous) require revision. The article also claims that there are diverse socio-cultural profiles due to the fact that there is never a single logic of differentiation of tastes, and that the results of the present research demand a new conceptual frame…
ICTV Virus Taxonomy Profile: Cystoviridae
2017
The family Cystoviridae includes enveloped viruses with a tri-segmented dsRNA genome and a double-layered protein capsid. The innermost protein shell is a polymerase complex responsible for genome packaging, replication and transcription. Cystoviruses infect Gram-negative bacteria, primarily plant-pathogenic Pseudomonas syringae strains. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the taxonomy of the Cystoviridae, which is available at http://www.ictv.global/report/cystoviridae.
DNA IN FORENSIC GENETICS
2008
Forensic molecular genetics has been evolved from a rapidly developing field into accepted forensic science, leading DNA databases with DNA profiles from suspects and convicted offenders. DNA evidence has taken a central role by carrying a significant weight for convictions in the court of justice, as well as by excluding innocent suspects early on in a criminal investigation. At present, a robust system for DNA typing has been established for paternity testing and forensic stain analysis in criminal casework. In addition, forensic biologist should be aware about the ethical and legal consequences of their research on the society and the criminal justice system. New technologies will only b…
