Investigating the Influence of First Principles of Instruction on Trauma Management Skills in Nursing Students.

Background: This study aimed to evaluate the effects of first principles of instruction on trauma management skills for undergraduate nursing students.

Method: Two hundred twenty-four nursing students from Fujian Medical University were divided into control and experimental groups. Participants in the experimental group applied first principles of instruction and introduced design modifications to acquire trauma management skills.

Improved Birefringence Activated by Tetrahedra Decorated with a Single Linear Unit.

Performance enhancement induced by structural modification has long been the target in materials science fields. Direct evidence to witness the effectivity of one strategy is challenging and necessary. In this work, a tetrahedra-decoration strategy was proposed to improve the birefringent performance sharply, namely decorating the tetrahedra with a single linear [S ] unit.

ABCQ: A New Family for the Design of Infrared Nonlinear Optical Materials by Coupling Octahedra and Tetrahedra Units.

Large second-harmonic generation (SHG) response and broad band gap are two important and competitive parameters. It is difficult to balance them out in one material. In this work, by coupling alkali earth metal (AEM) octahedra with large highest occupied molecular orbital (HOMO)-lowest unoccupied molecular orbital (LUMO) gap and nonlinear optical (NLO)-active tetrahedra units, nine noncentrosymmetric (NCS) compounds, belonging to a new quaternary chalcogenide family ABCQ with unique windmill-like [MgMQ] (M = Al, Ga; Q = S, Se) units constructed by alternated [MgQ] octahedra and [MQ] tetrahedra, are rationally designed and fabricated.

Applying formative evaluation in the mentoring of student intern nurses in an emergency department.

Objective: To explore the effectiveness of formative evaluation in the mentoring of student nursing interns in an emergency department.

Methods: A total of 144 intern nursing students in the emergency department of a tertiary care hospital in Fuzhou were selected as the study subjects from July 2020 to February 2021. Adopting quasi-experimental studies methods, the students were divided into the experiment group ( = 74) and the control group ( = 70), based on their practicing rotation times.

NaYBO: a new rare-earth borate with an infinite one-dimensional [BO] chain and a short ultraviolet cutoff edge.

A new rare-earth borate NaYBO was fabricated by the flux method. The compound crystallizes in the 1̄ group, and shows a three-dimensional network built by [BO] fundamental building blocks (FBBs) with [NaO], [NaO], and [YO] polyhedra. The [BO] FBBs are composed of five planar BO and three BO tetrahedra and connected corner-sharing to construct a unique one-dimensional (1D) [BO] infinity chain that is observed for the first time in the NaO-YO-BO system compound, enriching the structural diversity of rare-earth borate.

NHIOF and (NH)(IOF)·HO: A Series of Ammonium-Containing Fluoroiodates with Wide Band Gaps.

A series of ammonium-containing fluoroiodates, NHIOF and (NH)(IOF)·HO, with isolated [IOF] units have been fabricated by a fluorine-oxygen substitution strategy from NHIO. The two compounds crystallize in the orthorhombic system, but in different space groups, noncentrosymmetric 2 for NHIOF and centrosymmetric for (NH)(IOF)·HO, and show wide band gaps of 4.53 eV for (NHIOF) and 4.

Linear unit BN: a novel birefringence-enhanced fundamental module with sp orbital hybridization.

Inorganic planar π-conjugated groups are advantageous to generate large birefringence in optical functional materials, and many excellent materials contain CO, BO or BO, such as CaCO, α/β-BaBO (α/β-BBO), and KBeBOF (KBBF). In view of their microscopic structures, the common characteristics are the planar structures, which are regarded as birefringence-enhanced fundamental modules (FMs). Nowadays, exploring novel birefringence-enhanced FMs is becoming a burning issue.

SrBO: a new borate with a [BO] fundamental building block and an unwonted 2D double layer.

A new alkaline-earth metal borate, SrBO, was successfully synthesized by a high-temperature solution method. It crystallizes in the monoclinic space group 2/ (no. 14) and features a fundamental building block (FBB) [BO] which is composed of eight [BO] and six [BO] units.
