Abstract
Lithium–ion solvation governs the performance of lithium metal anode (LMA) by tuning its interfacial stability. Solvation degree is modulated by adopting fluorinated non-solvating cosolvents (FNSC) to induce anion-rich solvation structure which is beneficial in constructing mechanically stable interface to suppress lithium dendrite. However, FNSC exhibits low cathodic stability owing to their low lowest unoccupied molecular orbital (LUMO) level, aggravating long-term cycling of LMA. We establish that spectroscopically measured Lewis basicity and polarity are critical parameters for designing optimal non-solvating cosolvents. Non-fluorinated non-solvating cosolvents (NFNSC) proposed by our design rule (i.e. anisole, ethoxybenzene and furan) delivered 99.0 % coulombic efficiency over 1400 cycles. In these molecules, the aromatic ring delocalizes oxygen electron pairs and lowers solvation capability, confirmed by electrochemical cycling, Raman spectroscopy, and DFT binding energy calculation. Finally, the quantification of remaining NFNSC in the electrolytes using nuclear magnetic resonance spectroscopy proves their reductive stability for extended cycles.

Abstract
This study is the first report of the preparation of hydroxyethyl starch (HES) hydrogels rapidly crosslinked with divinyl sulfone in a single step and single pot. To develop the physical and chemical features of hydrogels, Graphene oxide (GO) nanoparticles were combined with the crosslinked HES. In addition to swelling studies, structural characterization of the samples was conducted with a scanning electron microscope (SEM) and transmission electron microscope (TEM), Fourier transform infrared (FTIR) spectroscopy, X-ray diffractometry (XRD), Brunauer–Emmett–Teller (BET) analysis and thermogravimetric analysis (TGA). For the removal of malachite green model dye by GO-HES, the effects of GO content, solution concentration, temperature, contact duration, dosage and pH on varying adsorption features were researched. Additionally, adsorption isotherms, kinetic and thermodynamic systematics were analyzed. The maximum adsorption capacity of GO-HES composite hydrogel was found to be 89.3 mg/g for Langmuir isotherm. The possible adsorption mechanism of the composite hydrogels for malachite green dye involved electrostatic, hydrogen bonding, and π–π interactions. In addition to reasonable cost and simple synthesis method, the prepared composite materials have potential use in wastewater treatment as adsorbents for the removal of dye from aqueous solutions due to efficient adsorption capacity.

Abstract
End-milling is a cutting technology that removes material from machined workpieces by end mill and is widely used to manufacture parts. Moreover, this process is prone to vibration due to low stiffness. Also, nitriding is a surface hardening process with lots of effects on mechanical properties. This study investigated the effect of gas nitriding on a nitrided end mill in comparison with an unnitrided end mill and showed significant improvement in vibration peak and RMS during end milling. To clarify the reason for this improvement this article carried out a modal test to show how nitriding affected the natural frequency and damping ratio of the nitrided and unnitrided samples and showed that tool rigidity remained the same while damping ratio increased so we claimed nitriding improved damping ratio without change of tool rigidity. For verifying this claim we modeled, meshed, and analyzed for obtaining tool natural frequency both for nitrided and unnitrided tool and compared with extracted natural frequencies from each tool FFT diagram during straight grooving. We showed that the natural frequencies were the same with less than 3 percent change so we concluded that nitriding led to better tool performance by increasing the damping ratio without any significant change in the tool stiffness.

Abstract
This study aimed to assess the relationship among carcass traits of meat line FUNAAB Alpha chicken genotype, to identify the components that defined bled weight in them using multivariate principal component regression. A total of 14 different carcass traits from sixty-eight birds were recorded and subjected to one-way analysis of variance to vet for sex effect. Phenotypic relationships among the carcass traits were also established to pave way for the principal component analysis. The results reveal significant effects between the traits measured. The male significantly (P<0.05) had greater mean values for the traits measured. Correlations among the considered carcass traits were found to be positive and significant ranging from r = 0.406 (LrWt) - 0.981 (EdWt) for the female chicken; r = 0.330 (Head Wt) - 0.978 (BdWt) for the male chicken. The extracted components PC1 to PC7 contributed 95.66% with PC1 accounting for 68.68% of the variability in the original parameters. Communality estimates varied from 0.466 (thigh weight) to 0.983 (liver weight). In the principal component regression models, Eviscerated weight accounted for 95% of the variation observed in bled weight. The use of PC1 as a single predictor, explained 96.4% of the variability, whilst combining PC1 and PC4 showed improvements in the variance explained (R2 = 96.7%) with a lower Mallow's cp (5.31). Using the principal components scores from the chicken morphometric traits was more appropriate than using the original traits in bled weight prediction.

Abstract
Background: End-of-life care education is required for nurses to acquire the clinical competence necessary for the improvement of the quality of end-of-life nursing care. The aim of this study was to determine the effect of nursing care education based on End-of-Life Nursing Education Consortium (ELNEC) on the knowledge and performance of nurses working in the intensive care unit (ICU).Materials and Methods: This quasi-experimental study was conducted with a pretest-posttest design. From among nurses working in the ICU of Golestan and Imam Khomeini hospitals in Ahvaz, Iran, 80 nurses were selected based on the inclusion criteria. They were randomly assigned to the intervention and control groups (40 people in each group) using a table of random numbers. Data were collected using a demographic characteristics form, the ELNEC Knowledge Assessment Test (ELNEC-KAT), ‎and the Program in Palliative Care Education and Practice Questionnaire (German Revised Version; PCEP-GR‎).Results: A significant difference was observed between the study groups in terms of the average knowledge score in all 9 modules including nursing care, pain management and control, disease symptom management, ethical/legal issues, culture, communication with the patient and his/her family, loss and grief, death, and quality of life (QOL) (P < 0.001). Moreover, the average performance score of nurses in the fields of preparation for providing palliative care, self-assessment of ability to communicate with dying patients and their relatives, self-assessment of knowledge and skills in palliative care increased significantly in the intervention group compared to the control group (P < 0.001).Conclusions: End-of-life nursing education is recommended as an effective method for promoting knowledge, attitude, performance, and clinical competence among all nurses involved in end-of-life care.

Abstract
Purpose

The purpose of this study is to explore the feasibility of identifying the intersegmental plane by arterial ligation alone during thoracoscopic anatomical segmentectomy.
Methods

We selected 35 patients with peripheral small lung nodules who underwent thoracoscopic anatomical segmentectomy between May and December 2020. First, the targeted segmental arteries were distinguished and ligated during the operation. Then, bilateral pulmonary ventilation was performed with pure oxygen to fully inflate the entirety pulmonary lobes. After waiting for a while, the intersegmental plane appeared. Finally, the intersegmental plane was observed using thoracoscopy after indocyanine green was injected into the peripheral vein. The intersegmental planes determined by these two methods were compared.
Results

Thirty-four patients underwent segmental resection and one patient finally underwent lobectomy. The intersegmental planes were successfully observed in all patients using the arterial ligation method. The time from contralateral pulmonary ventilation to the appearance of the intersegmental plane was 13.7±3.2 min (6-19 min). The intersegmental planes determined by the arterial ligation method and the fluorescence method were comparable. After the operation, CT examinations showed that the remaining lung segments of all patients were well inflated. The mean duration of closed thoracic drainage was 3.1±0.9 days.
Conclusion

The arterial ligation method can be used to determine the intersegmental plane in anatomical segmentectomy. The method is feasible, reliable, and safe.

Published: November 2021

Introduction. Myrtus communis, Aristolochia longa, and Calycotome spinosa are medicinal plants frequently used in Algeria. Some plants can cause a fragility of the erythrocyte membrane and lead to hemolysis. Therefore, we aimed to study the cytotoxicity of aqueous extracts from the aerial part of these species against red blood cells.
Study objects and methods. The hemolytic effect was determined spectrophotometrically by incubating an erythrocyte solution with different concentrations of the aqueous extracts (25, 50, 100, and 200 mg/mL) at 37°C during one hour. In addition, we performed phytochemical screening and measured the contents of polyphenols and flavonoids.
Results and discussion. After one hour of incubation of human red blood cells with the aqueous extracts at different concentrations, the hemolysis percentage showed a significant leak of hemoglobin with A. longa (68.75 ± 6.11%; 200 mg/mL), the most toxic extract followed by C. spinosa (34.86 ± 5.06%; 200 mg/mL). In contrast, M. communis showed very low cytotoxicity (20.13 ± 3.11%; 200 mg/mL).
Conclusion. These plants are sources of a wide range of bioactive compounds but their use in traditional medicine must be adapted to avoid any toxic effect.
Mechanisms of Smartphone Apps for Cigarette Smoking Cessation: Results of a Serial Mediation Model From the iCanQuit Randomized Trial
Authors: Bricker Jonathan B , Levin Michael , Lappalainen Raimo , Mull Kristin , Sullivan Brianna , Santiago-Torres Margarita 
Published: November 2021

Background
Engagement with digital interventions is a well-known predictor of treatment outcomes, but this knowledge has had limited actionable value. Instead, learning why engagement with digital interventions impact treatment outcomes can lead to targeted improvements in their efficacy.

Objective
This study aimed to test a serial mediation model of an Acceptance and Commitment Therapy (ACT) smartphone intervention for smoking cessation.

Methods
In this randomized controlled trial, participants (N=2415) from 50 US states were assigned to the ACT-based smartphone intervention (iCanQuit) or comparison smartphone intervention (QuitGuide). Their engagement with the apps (primary measure: number of logins) was measured during the first 3 months, ACT processes were measured at baseline and 3 months (acceptance of internal cues to smoke, valued living), and smoking cessation was measured at 12 months with 87% follow-up retention.

Results
There was a significant serial mediation effect of iCanQuit on smoking cessation through multiple indicators of intervention engagement (ie, total number of logins, total number of minutes used, and total number of unique days of use) and in turn through increases in mean acceptance of internal cues to smoke from baseline to 3 months. Analyses of the acceptance subscales showed that the mediation was through acceptance of physical sensations and emotions, but not acceptance of thoughts. There was no evidence that the effect of the iCanQuit intervention was mediated through changes in valued living.

Conclusions
In this first study of serial mediators underlying the efficacy of smartphone apps for smoking cessation, our results suggest the effect of the iCanQuit ACT-based smartphone app on smoking cessation was mediated through multiple indicators of engagement and in turn through increases in the acceptance of physical sensations and emotions that cue smoking.

Quand l’informel prend le pas sur le formel en période de crise: le cas de Bonoua (Côte d’Ivoire)
Authors: KOUADIO OURA RAPHAËL 
Published: November 2021

La agricultura le ha permitido a Bonoua ser una de las primeras regiones económicas del país, según Oura (2010). Ella atrae los migrantes hacia los campos, pero la ciudad guardará una parte. El auge agrícola creaba actividades en la ciudad. Pero el auge económico ha abierto la ciudad a una migración muy desarrollada de manera que la economía moderna no podía satisfacer sólo las demandas de los empleos de la población. Lo informal cobra importancia, pero la utilidad es precaria. Más del 58,5% de los pobres en 1999 practican una actividad informal contra 13,6% en la empresa moderna y 26,3% en la agricultura (Kouakou, 1999, p. 31). Pero una crisis agrícola interviene en el 2002 y la mayoría de la población invierte mucho más en el sector informal. Es así que la agricultura cede su lugar a la actividad informal. Una ciudad agrícola, Bonoua, toma poco a poco las características de una ciudad moderna. Pero la transición se hace progresivamente por el auge de lo informal.

Chess, visual memory and geometric transformations
Authors: Sosa Jorge Jhonattan Castellanos , Aguilar Francy Karina Maldonado 
Published: November 2021

This work shows how playing chess creates capacities in the student such as increasing visual memory. This helps to classify information in an orderly manner in the mind and contributes to a better understanding of geometric transformations such as displacements, turns and similarities. This was done with a mixed technique (Quantitative and Qualitative), starting with a structured questionnaire that was applied to 487 students. A case study was carried out with two students (one with and the other without notable chess skills) in two schools in Bogotá-Colombia, with the aim of understanding chess as a tool that can help the teacher to teach mathematics¡. In the quantitative part, data were collected by a structured questionnaire, and in the qualitative part, recordings and transcripts were made of what the two students reported in the case study. So, favorable results were achieved for students who usually play chess, because they show a great capacity for visual memory (in the long and short term) that contributes to a more optimal learning of displacements and similarities in the Cartesian plane. This research shows a powerful tool (chess) that can be used in the teaching of mathematics, thanks to the skills and concepts that are generated in the experience with the game.
