Chloridometh­yl(2-methyl­quinolin-8-olato-κ2 N,O)phenyl­tin(IV)

The asymmetric unit of the title complex, [Sn(CH3)(C6H5)(C10H8NO)Cl], consists of two independent mol­ecules, both of which have the N,O-chelated SnIV atom in a cis-C2SnNOCl trigonal-bipyramidal geometry [C—Sn—C = 124.82 (8) and 137.69 (8)°]. The Cl atom of the mol­ecule with the smaller C—Sn—C angle inter­acts weakly with the SnIV atom of the mol­ecule with the wider C—Sn—C angle at an Sn⋯Cl distance of 3.595 (1) Å. Weak inter­molecular C—H⋯O and C—H⋯Cl hydrogen bonding is present in the crystal structure

Predicting the Performance of Gorgan Wastewater Treatment Plant Using ANN-GA, CANFIS, and ANN Models

A reliable model for any wastewater treatment plant (WWTP) is essential to predict its performance and form a basis for controlling the operation of the process. This would minimize the operation costs and assess the stability of environmental balance. This study applied artificial neural network-genetic algorithm (ANN-GA) and co-active neuro-fuzzy logic inference system (CANFIS) in comparison with ANN for predicting the performance of WWTP. The result indicated that the GA produces more accurate results than fuzzy logic technique. It was found that GA components increased the ANN ability in predicting WWTP performance. The normalized root mean square error (NRMSE) for ANN-GA in predicting chemical oxygen demand (COD), total suspended solids (TSS) and biochemical oxygen demand (BOD) were 0.15, 0.19 and 0.15, respectively. The corresponding correlation coefficients were 0.891, 0.930 and 0.890, respectively. Comparing these results with other studies showed that despite the slightly lower performance of the current model, its requirement for a lower number of input parameters can save the extra cost of sampling

Medication Errors and its Contributing Factors among Midwives

Introduction: Medication errors are among the most serious health errors threatening patient safety in all countries, with major impacts on public health. Midwives as members of healthcare systems are prone to such errors. Therefore, in this study, we aimed to determine medication errors and the contributing factors among midwives working in maternity units of Mashhad University of Medical Sciences, Mashhad, Iran in 2015. Methods: This descriptive, cross-sectional study was performed on 104 employed midwives at four hospitals (Imam Reza, Ghaem, Omolbanin, and Hashemi Nezhad hospitals), affiliated to Mashhad University of Medical Sciences. The validity and reliability of the data collection tools were confirmed through content validity and internal consistency (Cronbach's alpha), respectively. For data analysis, descriptive and analytical tests, multiple linear regression, and negative binomial regression analysis were performed, using SPSS version 20 and STATA version 11. Results: The average incidence of medication errors for each midwife was 21.24±2.89 in the past six months. Among reasons against reporting medication errors, fear of confrontation with authorities (3.79±1.5) and attributing the medication error to individual factors by officials (3.88±1.34) had the highest average scores. The most common causes of medication errors were overcrowding of the ward (4.32±1.01), excessive workload and overexertion (4.19±1.08), and presence of critically ill patients in the ward (4.03±1.18). Conclusion: Overcrowding of the ward, fear of authorities, and attributing the medication error to individual factors were the main reasons against reporting medication errors, respectively. Therefore, more attention should be paid to error reporting systems, and workshops in this area are highly recommended

Biphenylene Nanotube: A Promising Anode Material for Sodium‐Ion Batteries

Abstract The properties of pristine and boron‐doped biphenylene nanotubes (BPNT and BBPNT, respectively) as anode materials for sodium storage are studied using density functional theory (DFT). To this end, the electronic properties, adsorption energy, diffusion energy barrier, open‐circuit voltage (OCV), and theoretical capacity are evaluated. The density of states calculations indicate that BPNT and BBPNT with zero band gap have a metallic character, which is critical for electron transferring in electrode materials. The calculation of adsorption energies suggests that the inside of the tube has better adsorption than the outside. Also, doping with boron improves the adsorption inside and outside the nanotube. Sodium ion sees three ways to penetrate from the outside to the inside of the tube. Calculations illustrate that the bigger ring with eight atoms with a 7.08 eV energy barrier, compared to the other cavities, is more appropriate for diffusion. This energy decreases to 5.84 eV after boron doping. The OCV profile of BBPNT confirms that this structure is in the acceptable voltage range for sodium‐ion batteries (SIBs). Finally, this work obtains a theoretical capacity of 403.82 mAh g−1 (without sodium clustering) for BBPNT, which confirms the potential of this structure for use in SIBs

The aim of the current study is to investigate the attitude and performance of MUMS faculties towards the implementation of ETS. Method: This descriptive – cross sectional study was carried out in 2009. The study population was faculties of MUMS (360). A stratified and randomize sampling method was used to select 86 faculties. Data gathering tool was a 38- item questionnaire. Data were analyzed using SPSS software. Result: About 65% of the study population was male and 35% female. 90.7% of faculties were completely agreed, 4.7% were totally agreed and 4.7% were totally disagreed with using ETS. About 46.5% of faculties were engaged in material preparation for the system, and 34.9% used ETS in their regular teaching courses. The common teaching methods among the faculties were lecture (3.72±1.3) and group discussion (3.47±1.07). Conclusion: Based on the positive attitude and performance of the MUMS faculties towards ETS, it is suggested that measures be taken to prepare the required infrastructure to use this system in teaching university courses

Effect of Aqueous Extract of Crocus sativus L. on Morphine-Induced Memory Impairment

In the present study, the effect of aqueous extracts of saffron on morphine-induced memory impairment was investigated. On the training trial, the mice received an electric shock when the animals were entered into the dark compartment. Twenty-four and forty-eight hours later, the time latency for entering the dark compartment was recorded and defined as the retention trial. The mice were divided into (1) control, (2) morphine which received morphine before the training in the passive avoidance test, (3–5) three groups treated by 50, 150 and 450 mg/kg of saffron extract before the training trial, and (6 and 7) the two other groups received 150 and 450 mg/kg of saffron extract before the retention trial. The time latency in morphine-treated group was lower than control (P < 0.01). Treatment of the animals by 150 and 450 mg/kg of saffron extract before the training trial increased the time latency at 24 and 48 hours after the training trial (P < 0.05 and P < 0.01). Administration of both 150 and 450 mg/kg doses of the extract before retention trials also increased the time latency (P < 0.01). The results revealed that the saffron extract attenuated morphine-induced memory impairment
