APPLICATIONS OF DIMENSIONAL ANALYSIS AND SIMILARITY THEORY IN HYDRAULICS

2018

Technological process, however complex, can be broken down into a succession of distinct component processes, in which the input materials undergo changes in shape (mechanical processes), pressure, temperature, concentration, state of aggregation (physical processes) or structure molecular (chemical and biochemical processes). The unitary operations of most process phases in process industries are based on three fundamental processes: pulse transfer, heat transfer, and mass transfer

Modeling bismuth insertion in 1D hybrid lead halide TMSO(Pb x Bi y )I3 pseudo-perovskites

2022

Abstract The structures of the disordered 1D (pseudo-)perovskites of general TMSO(Pb x Bi y )I3 formulation [TMSO = (CH3)3SO+], obtained by doping the TMSOPbI3 species with Bi3+ ions, are investigated through the formulation of a statistical model of correlated disorder, which addresses the sequences of differently occupied BI6 face-sharing octahedra (B = Pb, Bi or vacant site) within ideally infinite [(BI3)−] n chains. The x-ray diffraction patterns simulated on the basis of the model are matched to the experimental traces, which show many broad peaks with awkward (nearly trapezoidal) shapes, under the assumption that the charge balance is fully accomplished within each chain. The analysis…

Learning teamwork through a computer game: for the sake of performance or collaborative learning?

2021

AbstractOur study examined using a computer-based learning game as a tool to facilitate teaching and learning teamwork skills. The game was applied to an undergraduate level human resource management course at a business school in Finland. We focused on students’ experiences and key learning outcomes of collaborative learning of teamwork skills through the game, and our analysis highlighted two key features of learning outcomes. First, the computer-based learning game promoted students’ self-reflection and evaluation of their individual team roles. Second, although the game taught students the importance of continuous information sharing in teamwork, their evaluation of team outcomes was pe…

Huono johtaminen lääkärikontekstissa

2022

Tämän tutkimuksen tavoitteena on selvittää, millaisia ilmenemismuotoja huono johtaminen saa lääkärikontekstissa. Aineiston keruumenetelmänä käytettiin puolistrukturoitua haastattelua (n=50). Kaikki aineiston informantit ovat lääkäreitä. Tutkimusaineisto analysoitiin sisällönanalyysin avulla, jonka tuloksena syntyi huonon lääkärijohtamisen teemoittelu. Tätä teemajakoa täsmennettiin myös aiemman tutkimuskirjallisuuden avulla.Tutkimuksen tuloksilla toivotaan voitavan kehittää lääkäreiden työhyvinvointia ja lääkärijohtajan työtä terveydenhuollon muuttuvassa toimintaympäristössä siten, että lääkäreillä olisi tehtäväänsä motivoituneita ja tehtävässään viihtyviä lääkäreitä johtajinaan. This study …

Leaders’ intensified job demands : Their multi-level associations with leader-follower relationships and follower well-being

2022

To study the ever-increasing pace of work practices, we investigated leader experiences of intensified job demands (IJDs) and their effects on followers. Based on the challenge-hindrance approach, different kinds of job demands may produce either negative or positive work-related outcomes. Using this perspective, we investigated the leaders IJDs against their followers’ satisfaction with them as leaders, follower evaluations of the leader-member exchange (LMX) relationship quality, and their personal well-being (burnout and work engagement). Of the four IJDs, (1) work intensification and (2) career-related planning demands were conceptualised as negative hindrances for leaders, whereas (3) …
