IEEE Std. 1459 power quantities ratio approaches for simplified harmonic emissions assessment
2018
The paper investigates the suitability of using power ratio parameters for harmonic emissions assessment at the point of common coupling (PCC). The study is carried out starting from the IEEE Std. 1459-2010 apparent power decomposition, where power factors are defined for evaluating line utilization and harmonic pollution levels. In addition, the study investigates the behavior of new parameters, which are expressed in terms of ratio between IEEE Std. 1459-2010 power quantities. The study is carried out for both single-phase and three-phase case, also considering the presence of capacitors. ? 2018 IEEE.
Evolution of fluctuations in the initial state of heavy-ion collisions from RHIC to LHC
2019
Fluctuations in the initial state of heavy-ion collisions are larger at RHIC energy than at LHC energy. This fact can be inferred from recent measurements of the fluctuations of the particle multiplicities and of elliptic flow performed at the two different energies. We show that an analytical description of the initial energy-density field and its fluctuations motivated by the color glass condensate (CGC) effective theory predicts and quantitatively captures the measured energy evolution of these observables. The crucial feature is that fluctuations in the CGC scale like the inverse of the saturation scale of the nuclei.
Effective theory approaches to heavy meson resonances based on non-perturbative low energy two-meson dynamics
2019
This dissertation provides a theoretical effective description of a special class of hadronic meson states with charm and bottom quark content and their associated phenomenology. The considered states are difficult to be accommodated in CQMs and are candidates to be interpreted as meson molecules. This relies on the assumption that their main properties can be described by means of an effective low energy interaction of two more fundamental mesons. We have paid special attention to the relevant symmetries of QCD and two-body unitarity to construct the low energy effective meson-meson interactions. We have investigated the predictions of the Next-to-Leading Order (NLO) Unitary Heavy Meson Ch…
Maschilità egemone. FORMULAZIONE, RIFORMULAZIONE E DIFFUSIONE
2022
The concept of hegemonic masculinity, formulated by Raewyn Connell more than three decades ago, has been the driving force behind the expanding field of masculinities studies. Hegemonic Masculinity: Formulation, Reformulation, and Amplification provides the first comprehensive overview of the concept-from its original conception to how it has evolved over time. The book also examines some of the most powerful ways the concept is being used in contemporary gender studies. Hegemonic Masculinity describes the development of the concept, the actual formulation and initial applications of the concept, the eventual reformulation and subsequent applications of that reformulation, and finally, the …
Vīriešu mājdzemdību pieredzes naratīva analīze
2021
Maģistra darbā “Vīriešu mājdzemdību pieredzes naratīva analīze” mērķis ir noskaidrot vai un kā tēvu maskulinitāte ietekmē viņu mājdzemdību pieredzes stāstu veidošanu, izmantojot naratīva analīzi. Pētījuma ietvaros ir veiktas septiņas daļēji strukturētas intervijas ar tēviem, kuriem ir mājdzemdību pieredze. Intervijas analizētas izmantojot naratīva analīzi. Darba teorētiskais ietvars ir balstīts Reivinas Konnelas (Raewyn Connell) hegemoniskās maskulinitātes teorētiskā koncepta ietvaros. Tēvu maskulinitāte ietekmē pieredzes stāstu veidošanu, kā arī viņu izpratni par tēvu lomu ģimenē un attiecībās.
Hegemonās maskulinitātes diskurss: Latvijas X un Y paaudžu vīriešu interviju analīze
2020
Bakalaura darba “Hegemonās maskulinitātes diskurss: Latvijas X un Y paaudžu vīriešu interviju analīze” mērķis ir noskaidrot hegemonās maskulinitātes diskursu izvēlētās paaudzēs un uzzināt gan sabiedrības, gan vīriešu komunicēto viedokli par hegemonu maskulinitāti, izmantojot no intervijas ar vīriešiem, novērojuma un sabiedrības anketēšanas iegūtus datus. Pētījums balstās uz Rejenas Koneles un Mihaela Kimela atziņām par maskulīno hegemoniju, to izpausmēm un attiecībām ar citām maskulinitātēm. Kā Tajā arī tika aplūkoti jaunākie maskulinitātes pētījumi, tostarp arī par inkluzīvās un toksiskās maskulinitātēm. Pētījuma īstenošanai bija izmantotas 4 metodes: kvantitatīvā aptauja (kopumā 244 respo…
From the forest to the plate – Hemicelluloses, galactoglucomannan, glucuronoxylan, and phenolic-rich extracts from unconventional sources as function…
2021
This study aimed to characterise pressurised hot water (PHW) extracts from nonconventional sources of functional carbohydrates and phenolic compounds in terms of antioxidant capacity, antiviral activity, toxicity, and human erythrocytes’ protection antidiabetic potential. PHW extracts of Norway spruce bark (E1 + E2) and Birch sawdust (E3 + E4) contained mostly galactoglucomannan and glucuronoxylan. In contrast, samples E5 to E9 PHW extracted from Norway spruce, and Scots pine bark are rich sources of phenolic compounds. Overall, phenolic-rich extracts presented the highest inhibition of α-amylase and α-glucosidase and protection against stable non-enveloped enteroviruses. Additionally, all …
Maidon proteiinifraktioiden vaikutus ihmisen luuydinperäisten mesenkymaalisten kantasolujen kuntoon ja luusoluerilaistumiseen
2012
On yleisesti tiedossa, että maito on terveellistä ja parantaa luun kestävyyttä. Tutkimusten perusteella osa maidon proteiineista lisää luuta muodostavien osteoblastien määrää ja ehkäisee luun haurastumista estämällä esiosteoklastien erilaistumista luuta hajottaviksi osteoklasteiksi. Osteoblastit erilaistuvat multipotenteista mesenkymaalisista kantasoluista. Tällöin maidon proteiineilla saattaa olla fysiologinen rooli luun kasvamisessa ja paranemisessa. Maidon proteiineilla voi olla myös terapeuttinen vaikutus osteoporoosin anabolisena tekijänä. Tutkimus oli osa Valion ja Turun yliopiston yhteistyöprojektia. Tutkimuksen tarkoituksena oli testata maidon seitsemän proteiinifraktion vaikutuksia…
Mathematical modelling of sustainable bioresidual concrete
2019
In the production of cement, which is the main component of concrete production, the process generates about 5% of the global carbon dioxide emissions. In addition, bioproduct and pulp mills produce signi_cant quantities of soda ash and bio-ash, which is still largely unused. In this paper we will introduce our study related to improving the environmental friendliness of concrete used in construction by utilizing pulp mill waste while its long-term durability and strength and porosity properties meet the goals set for construction. The project `sustainable bioresidual concrete' is on-going and only preliminary numerical results with measurements are presented here. peerReviewed
