A novel NHC complex of silver(I) ion, 1-pentamethylbenzyl-3-(n)buthylbenzimidazolesilver(I)bromide, was prepared and fully characterized by single crystal X-ray structure determination. FT-IR, NMR and UV-vis spectroscopies were employed to investigate the electronic transition behaviors of the complex. Additionally, the molecular geometry, vibrational frequencies, gauge including atomic orbital (GIAO) (1)H and (13)C chemical shift and electronic transition values of silver(I) complex were calculated by using density functional theory levels (B3LYP and PBE1PBE) with LANL2DZ basis set. Also, the vibrational frequencies were supported on the basis of the potential energy distribution (PED) analysis calculated for PBE1PBE level. We were also investigated total static dipole moment (μ), the mean polarizability (〈α〉), the anisotropy of the polarizability (Δα), the mean first-order hyperpolarizability (〈β〉) of the title complex. Natural bond orbital (NBO) analysis was performed to determine the presence of hyperconjugative interactions, and charge distributions.

This study presents the design of a high-gain 16 × 16-slot antenna array with a low sidelobe level (SLL) using a tapered ridge gap waveguide feeding network for Ka-band applications. The proposed antenna element includes four cavity-backed slot antennas. A tapered feeding network is designed and utilized for unequal feeding of the radiating elements.

Introduction: The transition of adolescents from pediatric to adult hospitals is a planned and guided process that involves changes in the focus, style, and location of care. During this period, complications are common in those with type 1 diabetes mellitus (T1DM). The objective of this study was to understand the influence of a nurse-led structured therapeutic education program on maintaining glycemic control and emotional wellbeing in these adolescents.

The IR polarization spectrum of acetylacetone enol (AAe, (3Z)-4-hydroxy-3-penten-2-one) was recorded in the region 2000 - 450 cm using stretched polyethylene as an anisotropic solvent. The measured orientation factors were consistent with C molecular symmetry of AAe and provided an experimental distinction between in-plane and out-of-plane polarized spectral features. The results suggest the assignment of at least one previously unrecognized fundamental transition.

Background: There is an under-reporting of anaesthesia-related safety events. Incident-capturing systems (ICSs) are essential for patient safety monitoring, identifying risks and ongoing opportunities for improvement. After a literature review and assessment of our current ICSs, we concluded that our institution lacked a reliable anaesthesia-specific ICS system, leading to under-reporting of anaesthesia-related safety events.

Background: Recent studies show that the increase in breath hydrogen (BH) and symptoms after ingestion of inulin is reduced by co-administering psyllium.
Objectives: To determine if slowing delivery of inulin to the colon by administering it in divided doses would mimic the effect of psyllium. Primary endpoint was the BH area under the curve AUC.
