Methyl 3',5'-dimethoxybiphenyl-4-carboxylate

2013

In the title compound, C16H16O4, the dihedral angle between the benzene rings is 28.9 (2)°. In the crystal, mol­ecules are packed in layers parallel to the b axis in which they are connected via weak inter­molecular C-H...O contacts. Face-to-face π-π inter­actions also exist between the benzene rings of adjacent mol­ecules, with centroid-centroid and plane-to-plane shift distances of 3.8597 (14) and 1.843 (2) Å, respectively.

Methyl 3',4',5'-trimethoxybiphenyl-4-carboxylate

2013

In the title compound, C17H18O5, the dihedral angle between the benzene rings is 31.23 (16)°. In the crystal, the mol­ecules are packed in an anti­parallel fashion in layers along the a axis. In each layer, very weak C-H...O hydrogen bonds occur between the meth­oxy and methyl ester groups. Weak C-H...[pi] inter­actions between the 4'- and 5'-meth­oxy groups and neighbouring benzene rings [meth­oxy-C-ring centroid distances = 4.075 and 3.486 Å, respectively] connect the layers.

1,1,4,4-Tetramethylpiperazinediium dibromide

2009

A small quantity of the title compound, C8H20N22+·2Br−, was formed as a by-product in a reaction between a diamine and an alkyl bromide. The asymmetric unit contains half of a centrosymmetric dication and a bromide anion. In the crystal, weak intermolecular C—H...Br hydrogen bonds consolidate the crystal packing.

Online interventions to prevent mental health problems implemented in school settings: the perspectives from key stakeholders in Austria and Spain

2021

Abstract Background Schools are key settings for delivering mental illness prevention in adolescents. Data on stakeholders’ attitudes and factors relevant for the implementation of Internet-based prevention programmes are scarce. Methods Stakeholders in the school setting from Austria and Spain were consulted. Potential facilitators (e.g. teachers and school psychologists) completed an online questionnaire (N=50), policy makers (e.g. representatives of the ministry of education and health professional associations) participated in semi-structured interviews (N=9) and pupils (N=29, 14–19 years) participated in focus groups. Thematic analysis was used to identify experiences with, attitudes a…

Ultrasound bioeffects in rats: quantification of cellular damage in the fetal liver after pulsed Doppler imaging

2011

Objective To determine whether pulsed Doppler examination of the ductus venosus in rat fetuses could damage exposed tissue. Methods On gestational day 18, the livers of a mean of approximately five fetuses per mother (n = 5.14, SD = 1.6), in a cohort of 35 pregnant female rats, were exposed individually to pulsed Doppler and these were considered the 'exposed group'. The remaining fetuses in each pregnant rat (n = 5.16, SD = 2.1) formed the 'control group'. We tested for 600, 300, 60, 20, 15, 10 and 3 s of exposure of the fetal ductus venosus and the damage was evaluated measuring a cell death index of apoptotic activity at 7 h post-exposure (n = 16). In addition, subgroups of mothers were …

Controlling the crystal growth of potassium iodide with a 1,1'-bis(pyridin-4-ylmethyl)-2,2'-biimidazole ligand (L) – formation of a linear [K4I4L4]n …

2018

The crystal growth of potassium iodide was controlled by using the neutral organic 1,1′-bis(pyridin-4-ylmethyl)-2,2′-biimidazole (L) ligand as a modifier. The selected modifier allows the preservation of original cubic [K4I4] units and their arrangement into a linear ligand-supported 1D chain. The supported [K4I4] cubes are only slightly distorted compared to the cubes found in pure KI salt. The N–K binding of the ligand to the KI salt, as well as weak I⋯H, N⋯H, and N⋯I interactions, stabilizes the structure to create a unique 1D polymer of neutral potassium iodide ionic salt inside the [K4I4L4]n complex.

Patient Education as an Information System, Healthcare Tool and Interaction

2014

Patient education (PE) has a crucial role in the function of a healthcare organisation. For the care process of a patient, it is essential to get the right information at the right moment and in the right form. This paper analyses PE as the primary mode of interaction between a patient and a healthcare organisation. The approach is illustrated with a study among nurses based on their conceptions about PE. Practical implications and the potential of ICT in PE in particular are discussed. peerReviewed

Szkoła środowiskowa czy szkoła osadzona w środowisku. W poszukiwaniu modelu współpracy midzy środowiskiem lokalnym a szkołą

2016

The article deals with the question of the realization in the Polish context the idea of "environmental school" and "the school placed in the environment". The author opts for the other concept as the real strategy of building a good school, looking for its identity, referring to the cultura! and historical heritage of local environment, based on the local relations network in which local environment participates.
