Bilevel heat exchanger network synthesis with an interactive multi-objective optimization method
2012
Abstract Heat exchanger network synthesis (HENS) has been an active research area for more than 40 years because well-designed heat exchanger networks enable heat recovery in process industries in an energy- and cost-efficient manner. Due to ever increasing global competition and need to decrease the harmful effects done on the environment, there still is a continuous need to improve the heat exchanger networks and their synthesizing methods. In this work we present a HENS method that combines an interactive multi-objective optimization method with a simultaneous bilevel HENS method, where the bilevel part of the method is based on grouping of process streams and building aggregate streams …
SERS detection of cell surface and intracellular components of microorganisms using nano-aggregated Ag substrate
2016
Abstract The intracellular and cell surface composition and structural features of gram-positive and gram-negative bacteria were identified using near-infrared surface-enhanced Raman scattering (SERS). The structural differences of components that reside in the cell envelope are manifested by their SERS spectra, e.g. gram-negative vs. gram-positive. Silver particles were used as a SERS substrate by exploiting the existence of strong local electromagnetic fields (hot spots) within nanoscale aggregates of the particles. The aggregation of silver nanoparticles was induced by magnesium ions. These hot spots reduce the screening length of the double layer. The obtained SERS spectra showed excell…
Gender segregation in the employment of higher education graduates
2014
This article examines the employment and placement in the working life of Finnish higher education graduates (i.e. graduates from universities and polytechnics), focusing on gender equality. It reports a study on gender segregation in higher education and working life, considered in relation to Nordic gender equality policies. The data were gathered via a questionnaire administered to graduates in business and administration (n = 1067) and in technology (n = 1087), three years after their graduation. The results showed that men were able to secure permanent and full-time employment more often than women, and men achieved better correspondence between their degree and their employment. Howev…
Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia
2018
The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
Työtä, turvaa ja tasa-arvoa! : työpreferenssit ja työelämään sijoittuminen vastavalmistuneilla AMK-insinööreillä
2015
Tämän tutkimuksen tehtävänä on selvittää vuonna 2013 valmistuneiden AMK-insinöörien työuran alkuvaiheita. Tavoitteena on tuottaa tietoa työllistymisestä, työpreferensseistä ja preferenssien taustalla olevista tekijöistä. Tutkimus on kvantitatiivinen sekundäärianalyysi, joka pohjautuu Insinööriliiton toimesta kesällä 2014 tekemääni vastavalmistuneiden sijoittumistutkimukseen. Tutkimuksen perusjoukon muodostavat kyselyhetkellä Insinööriliittoon (IL) ja diftingenjörsförbundet i Finland:iin (DIFF) kuuluneet, vuonna 2013 valmistuneet insinöörit. Kyselylomake lähetettiin 1600 vuonna 2013 valmistuneelle insinöörille, joista viisi prosenttia oli DIFF: in jäseniä. Vastauksia tuli yhteensä 794 kappal…
Troska o sprawy Kościoła w korespondencji ostatniej dekady życia Grzegorza z Nazjanzu
2016
Analysis of approximately 165 letters of Gregory Nazianzen written by him in the last decade of his life revealed a large part of them devoted to his involvement in the current affairs of the ecclesial community. His departure from the position of the bishop of Constantinople, marked by a kind of failure, did not prompt him to react against the Church, but developed just an opposite attitude – increased mobilization of his strenght for the constant concern about the situation of the local Churches. This concern referred to the activities of the pastors of particular ecclesial communities, experiencing a variety of problems, deacons and presbyters, coming from his surroundings, as well as sy…

Antiagregantu un antikoagulantu aprite aptiekās četros Latvijas reģionos laika periodā 2013.-2015. gads
2017
Trombam nosprostojot asinsvadus, var rastiem nopietnas, dzīvībai bīstamas saslimšanas: miokarda infarkts, insults, dziļo vēnu tromboze vai plaušu embolija. Maģistra darbā ir apkopota informācija par realizētajiem antitrombotiskajiem līdzekļiem (antikoagulantiem un antiagregantiem) 4 aptiekās, kuras atrodas dažādās pilsētās – Rīgā, Jelgavā, Daugavpilī un Liepājā. Patēriņa dati tika salīdzināti pēc DDD/1000 iedzīvotājiem/dienā. Rēķinot pēc DDD/1000 iedzīvotājiem/dienā, rezultāti parāda to, ka visās 4 aptiekās lielāks pieprasījums ir pēc antiagregantiem nekā antikoagulantiem. Rezultātos var redzēt arī to, ka vislielākais antitrombotisko medikamentu patēriņš ir Rīgas aptiekā, savukārt vismazāk …
Urban Segregation and Unemployment: A Case Study of Marseille (France)
2015
International audience; In this paper, we study the effects the Marseille’s spatial organization on unemployment. More specifically, differences in characteristics of residential population induce urban stratification so that the urban structure could affect the propensity of unemployment. This potential link is called the reverse causality. In order to evaluate the effect s of spatial structure on unemployment, we implement a spatial probit model to reveal the employment probabilities of young adults still living with their parents. In a first step, we highlight the realness of residential segregation in Marseille by a topology of neighborhoods by degree of deprivation with a principal com…
Observation of the Early Structural Changes Leading to the Formation of Protein Superstructures.
2014
Formation of superstructures in protein aggregation processes has been indicated as a general pathway for several proteins, possibly playing a role in human pathologies. There is a severe lack of knowledge on the origin of such species in terms of both mechanisms of formation and structural features. We use equine lysozyme as a model protein, and by combining spectroscopic techniques and microscopy with X-ray fiber diffraction and ab initio modeling of Small Angle X-ray Scattering data, we isolate the partially unfolded state from which one of these superstructures (i.e., particulate) originates. We reveal the low-resolution structure of the unfolded state and its mechanism of formation, hi…
