Evolutionary Study of Disorder in Protein Sequences

2020

Intrinsically disordered proteins (IDPs) contain regions lacking intrinsic globular structure (intrinsically disordered regions, IDRs). IDPs are present across the tree of life, with great variability of IDR type and frequency even between closely related taxa. To investigate the function of IDRs, we evaluated and compared the distribution of disorder content in 10,695 reference proteomes, confirming its high variability and finding certain correlation along the Euteleostomi (bony vertebrates) lineage to number of cell types. We used the comparison of orthologs to study the function of disorder related to increase in cell types, observing that multiple interacting subunits of protein comple…

A hierarchical model for novel schemes of electrodialysis desalination

2019

Abstract A new hierarchical model for the electrodialysis (ED) process is presented. The model has been implemented into gPROMs Modelbuilder (PSE), allowing the development of a distributed-parameters simulation tool that combines the effectiveness of a semi-empirical modelling approach to the flexibility of a layered arrangement of modelling scales. Thanks to its structure, the tool makes possible the simulation of many different and complex layouts, requiring only membrane properties as input parameters (e.g. membrane resistance or salt and water permeability). The model has been validated against original experimental data obtained from a lab scale ED test rig. Simulation results concern…

Can the absence of solvation of neutral reagents by ionic liquids be responsible for the high reactivity in base-assisted intramolecular nucleophilic…

2005

[reaction: see text] The kinetics of the rearrangement of the Z-phenylhydrazone of 3-benzoyl-5-phenyl-1,2,4-oxadiazole (1a) into the relevant 4-benzoylamino-2,5-diphenyl-1,2,3-triazole (2a) induced by amines have been studied in two room-temperature ionic liquids (IL-1, [BMIM][BF4] and IL-2, [BMIM][PF6]). The data collected show that the reaction occurs faster in ionic liquids than in other conventional solvents previously studied (both polar or apolar, protic or aprotic). Presumably, this could depend on their peculiar ability to minimize the strong substrate-solvent, amine-solvent and amine-amine interactions occurring in conventional solvents.

Thiourea Based Tritopic Halogen Bonding Acceptors

2023

Series of thiourea based tritopic receptor molecules were synthesized to be used as building blocks for halogen-bonded assemblies. Here 16 new receptor molecules were synthesized from two different 2,4,6-trialkyl-1,3,5-tris(bromomethyl)benzene starting materials via tris(isothiocyanatomethyl)benzene intermediates. The alkyl substituents in the benzene ring showed to be important for isothiocyanate group formation instead of competing thiocyanate group. The synthesis route allowed us to synthesize the isothiocyanate intermediates and further the receptor molecules without typically used and highly toxic thiophosgene. Synthesized receptor molecules were used to study their halogen bond accept…

Kokeilu kirjoittamisen itsearvioinnista tietokoneella

2001

This article discusses an experiment which we are conducting in the field of Finnish as a second language. We are developing an Internet-based program that learners of Finnish can use to assess their own writing skills. The program code originally comes from the DIALANG project, which is developing a diagnostic language assessment system for 14 languages for the Internet. We selected two new writing tasks for the program, and constructed related sets of benchmark performances to enable the learners to assess their own abilities. In the article, we first discuss the concepts of learner autonomy and self-assessment, in other words the theoretical framework that underlies the program. This is …

Mitä opin? Monilukutaitoa ja tutkivaa oppimista monialaisessa oppimiskokonaisuudessa

2019

Tarkastelemme tässä artikkelissa, mitä oppilaat, opettajat ja opettajaopiskelijat raportoivat oppineensa yhdessä toteuttamassaan monialaisessa oppimiskokonaisuudessa, johon osallistuivat erään yhtenäiskoulun kaikki 5.–8. luokan oppilaat. Oppimiskokonaisuuden aihe oli terve elämä ja sitä opiskeltiin viikon ajan ikäsekoitteisissa ryhmissä tutkivan oppimisen keinoin ja monilukutaitoa harjaannuttaen. Tutkimusaineisto koostuu 250 oppilaan, 25 opettajan ja 23 opettajaopiskelijan laadullisista itsearvioinneista, ja se analysoitiin laadullisen aineistolähtöisen teoriaohjaavan sisällönanalyysin keinoin. Tulosten mukaan oppilaat kertoivat oppineensa vuorovaikutustaitoja ja monimuotoisten tekstien tuo…

Authentic assessment as a support for student teachers’ reflection

2023

Assessment and feedback guide learning. In light of this, the assessment practices of teacher education have received little research. This qualitative study examines student teachers’ discussions in a study unit built on authentic assessment practices: self- and peer assessment of videotapes from authentic performance with research-based rubrics. The aim is to investigate whether authentic assessment supports student teachers’ reflection and, if so, how. The findings show that authentic assessment led students frequently to reflection, and in most cases reflective discussions were induced by students’ self-criticism. We deduced that the encouraging feedback culture between students and bet…

The dynamics of the financial capital – intellectual capital binomial relationship regarding the value creation process of a firm in the knowledge-ba…

2009

The idea that the value of the firm is given by its financial capital and its intellectual capital is generally accepted. But, what is changing nowadays is the importance/weight that each one of these two components claims to have regarding the value of the firm – based on the dynamics of the changes and the intensity of the competition within an industry, on one hand, and on the measure of connection/networking to the knowledge-based economy of the given industry, on the other hand. So, we are the witnesses of: (1) a repositioning into the dynamics of the financial capital – intellectual capital binomial relationship regarding the value creation process of a firm and (2) the need to reform…
