Synthesis, X-ray Crystal Structure and Antimicrobial Activity of Unexpected Trinuclear Cu(II) Complex from s-Triazine-Based Di-Compartmental Ligand v…
2019
The synthesis and X-ray crystal structure of the trinuclear [Cu3(HL)(Cl)2(NO3)(H2O)5](NO3)2 complex of the s-triazine-based di-compartmental ligand, 2-methoxy-4,6-bis(2-(pyridin-2-ylmsethylene)hydrazinyl)-1,3,5-triazine (H2L), are presented. The Cu1 and Cu2 are penta-coordinated with CuN3ClO coordination environment, distorted square pyramidal coordination geometry while Cu3 is hexa-coordinated with CuN2O4 coordination sphere, and distorted octahedral geometry. The complex crystallized in the primitive P-1 triclinic crystal system with two molecular units per unit cell. Its packing is dominated by the O–H (35.5%) and Cl–H (8.8%) hydrogen bonding interactions as well as the π–π stacking (2.3…
„Kimże jest człowiek, że [go]... wychowujesz?” (por. Ps 8,5). Antropologia pedagogiczna w katechezie
2017
Antropologia chrześcijańska szuka początków Biblii i tradycji Kościoła, aby sprzeciwiać się różnym błędnym wizjom ludzkości i odkryć wzajemne relacje z teologią, pedagogiką i katechezą. Integralne postrzeganie człowieka pozostaje kwestią szczególnie ważną w procesie katechetycznym. W celu zachowania właściwej harmonii w tym procesie konieczne jest zachowanie proporcji między antropologią a teologią, jak również między antropologią a pedagogiką. Antropologia pedagogiczna pomaga rozpoznać aktywność Bożą w całym procesie formacyjnym, biorąc pod uwagę specyfikę sytuacji życiowej konkretnych odbiorców Słowa Bożego, aby można było dać swobodę odpowiedzi na wezwanie Boga. Dlatego człowiek nie tylk…

X-Ray structure, Hirshfeld analysis and DFT studies of two new hits of triazolyl-indole bearing alkylsulfanyl moieties
2021
Two new hits of triazolyl-indole containing two different alkylsulfanyl analogues named tert-butyl 2-((4-amino-5-(1H-indol-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetate 2, and ethyl 2-((4-amino-5-(1H-indol-2-yl)-4H-1,2,4-triazol-3-yl)thio)acetate 3 were synthesized via reaction of 4-amino-5-(1H-indol-2-yl)-1,2,4-triazol-3(2H)-thione 1 with tert-butyl bromoacetate and ethyl chloroacetate in the presence of base (Et3N). The molecular structure of 2, and 3 was confirmed by single-crystal X-ray diffraction and 1H/13C- NMR spectroscopic techniques. In compound 2, the molecular packing depends on significant O...H (9.3%), N...H (12.4%) and S...H (3.1%) as well as relatively weak C...H (14.1%), S...C (…
Heijastavatko työn ja perheen yhteensovittamisen kokemukset yksilön elämänarvoja?
2014
Tässä tutkimuksessa tarkasteltiin yksilön elämänarvojen yhteyttä työn ja perheen välisen ristiriidan ja rikastavuuden kokemuksiin. Analyysit perustuivat 50-vuotiaisiin Lapsesta aikuiseksi - pitkittäistutkimuksen osanottajiin (n = 156, 53 % miehiä). Schwartzin (1992) menetelmällä tarkastellut elämänarvot olivat hyväntahtoisuus, universalismi, turvallisuus, yhdenmukaisuus, hedonismi, itseohjautuvuus, suoriutuminen, stimulaatio, traditiot ja valta. Suoriutuminen ja universalismi olivat myönteisesti yhteydessä sekä työn ja perheen välisen ristiriidan että rikastavuuden kokemuksiin. Sen sijaan stimulaatio oli myönteisesti yhteydessä vain ristiriidan ja yhdenmukaisuus vain rikastavuuden kokemuksi…
Changes in surface stress, morphology and chemical composition of silica and silicon nitride surfaces during the etching by gaseous HF acid
2007
International audience; HF acid attack of SiO2 and Si3N4 substrates is analyzed to improve the sensitivity of a sensor based on inicrocantilever. Ex situ analysis of the etching using XPS, SIMS and AFM show significant changes in the anisotropy and the rate of the etching of the oxides on SiO2 and Si3N4 surface. Those differences influence the kinetic evolution of the plastic bending deflection of the cantilever coated with SiO2 and Si3N4 layer, respectively. The linear dependence between the HF concentration and the Si3N4 cantilever bending corresponds to a deep attack of the layer whereas the nonlinear behavior observed for SiO2 layer can be explained by a combination of deep and lateral …
Synthesis, Structure and Antimicrobial Activity of New Co(II) Complex with bis-Morpholino/Benzoimidazole-s-Triazine Ligand
2023
A new Co(II) perchlorate complex of the bis-morpholino/benzoimidazole-s-triazine ligand, 4,4′-(6-(1H-benzo[d]imidazol-1-yl)-1,3,5-triazine-2,4-diyl)dimorpholine (BMBIT), was synthesized and characterized. The structure of the new Co(II) complex was approved to be [Co(BMBIT)2(H2O)4](ClO4)2*H2O using single-crystal X-ray diffraction. The Co(II) complex was found crystallized in the monoclinic crystal system and P21/c space group. The unit cell parameters are a = 22.21971(11) Å, b = 8.86743(4) Å, c = 24.38673(12) Å and β = 113.4401(6)°. This heteroleptic complex has distorted octahedral coordination geometry with two monodenatate BMBIT ligand units via the benzoimidazole N-atom and four water …
Building interpersonal trust in business networks: enablers and roadblocks
2019
Purpose - This study examines how interpersonal trust forms in business networks and anchors relationships. Trust can be seen as a required factor and enabler for co-creation that is needed when business models are created. This study draws on empirical data from a case study of a Finnish business network in the healthcare and pharmaceutical industries. It seeks to answer the research question: How does interpersonal trust start to develop at the business network level and how it can be supported? Design/ methodology/approach – This article draws on a case study of a Finnish business network which was developed through theme interviews and observation conducted in 2012. Findings - The findi…
Haptic Visuality and Film Narration. Mapping New Women’s Cinema in Spain
2020
There is a trend in female film production in the 21st century in the context of Spain towards a type of cinema that we could classify as haptic. It is a mode of representation concerned with multisensory expression in film images. In this article, we shall study this haptic visuality in the works of four filmmakers: Isabel Coixet, Paula Ortiz, Mar Coll and Carla Simón, whose films in this century exemplify the trend. The method chosen is textual analysis, which will provide us with the necessary tools to study matters concerning representation (framing), narration (nuclei and catalysis) and communication (spectatorial subject). These three analytical categories together will enable us to s…
Ethical Leaders Promote Quality of Life Through Fair and Trust-based Relationships
2020
Ethical leadership has become an important field of research. This article examines the impact of ethical leadership within the context of healthcare organizations. Based on social learning theory, we examine the relationship between ethical leadership and quality of life, mediated by peer justice and moderated by trust in the leader. Participants in this study consisted of 388 professionals from 59 centers affiliated with “Plena Inclusión”, an NGO whose mission is to improve the quality of life of individuals with intellectual disabilities in Spain. Results showed a significant relationship between ethical leadership and quality of life, through a partial mediation of overall peer justice.…
