Published: December 2020

Creativity is a human resource that allows individuals to solve problems in a new way and propose changes. It is related to creative self-efficacy that regards individual belief to be creative. The present study explored the effects of a training to enhance creativity and creative self-efficacy in 34 Italian children, aged between 8 and 10 years and divided in two groups: Group1 (training) and Group2 (no training). Test of Divergent Thinking and the Creative Self-efficacy Scale were modified for Italian children. After training, Group1 increased inflexibility, elaboration and title production; and Group2increased in titles production; all children showed higher levels of self-efficacy than before training. After training, positive relationships between creative self-efficacy, elaboration and titles production emerged for Group1.

Keywords: Creativity, self-efficacy, training, children.

Published: December 2020

Problem statement: Investigating numerous articles and studies on the effects of dance on the body, we can say that this type of movement brings many benefits to our health both physically and mentally regardless of the age. Purpose of study: This paper aims to analyse the level of stress in students aged 13–14 years, as well as reducing the level of stress felt by them by applying dance therapy. Study hypothesis: Indicators of stress (such as anxiety, emotional distress, etc.) can be improved with a focused dance-intervention therapy program, created specifically for this purpose. Objectives of the study proposed by us take into account the well-being of young people, more precisely of students aged 13–14. We intend to reduce stress by applying intervention plans based on a succession of specific dance steps, an artistic program created by us especially for this purpose. Subjects, duration and place of study: The study took place between October 2016 and January 2017, in Cluj-Napoca, in the gym of the ‘George Baritiu’ National College, a number of 30 students. Tests and assessment tools used in research: To find out the emotional state of students, we apply: Relaxation technique R. Bandler, Jacobson, Endler Scale of Multidimensional Anxiety Assessment Test – Endler Scales for Multidimensional Anxiety Assessment (Anxiety Scale), Emotional Distress Profile. We use Statistical Package for the Social Sciences, for the analysis of three or more samples, the analysis of variance test was used in the case of data with normal distribution or the non-parametric Kruskal–Wallis test, in the case of values with uneven distribution or ranks. Conclusions and recommendations: The obtained results underline the importance of using psychological tests to detect the level of stress in order to decrease its intensity and to raise awareness of well-being. Following the results obtained, which are statistically significant, we conclude that students need a special intervention program created by us that will reduce the accumulated stress.

The aim of this study is to investigate the relationship between metacognitive awareness and beliefs of pre-service teachers’ sense of efficacy. The research has been designed within a relational survey model. The sample of the research consists of 312 pre-service teachers. In the research, metacognitive awareness inventory and teachers’ sense of efficacy scale were used as data collection tools. The correlation between variables was examined using structural equation modelling. The results showed that there was a positive and significant correlation between metacognitive awareness and teachers’ sense of efficacy. This result interprets that an individual with high metacognitive awareness has a high teacher’s sense of efficacy.

Extended Trochanteric Osteotomy in Revision Total Hip Arthroplasty
Authors: Abdel Matthew P. , Wyles Cody C. , Viste Anthony , Perry Kevin I. , Trousdale Robert T. , Berry Daniel J. 
Published: December 2020

Background:
Extended trochanteric osteotomies (ETOs) provide wide femoral and acetabular exposure, give direct access to the femoral medullary canal, and facilitate implant removal and new implant placement during selected revision total hip arthroplasties (THAs). Previous studies are limited by modest patient numbers and limited length of follow-up. The goals of the current study were to assess the union rate, complications, and outcomes of contemporary ETOs performed during revision THAs.

Methods:
From 2003 to 2013, 612 ETOs were performed during revision THAs at 1 institution using 2 techniques: Paprosky (laterally based osteotomy; n = 367) and Wagner (anteriorly based osteotomy; n = 245). The indications for the revision procedures were aseptic loosening (65%), periprosthetic joint infection (18%), periprosthetic fracture (6%), femoral implant fracture (5%), and other (6%). The mean patient age was 69 years, and 57% of the patients were male. The mean number of previous THAs was 1.6. The median duration of follow-up was 5 years (range, 2 to 13 years).

Results:
The mean Harris hip scores increased from 57 preoperatively to 77 at the latest follow-up (p < 0.001). Radiographic and clinical union was achieved in 98% of the patients at a mean of 6 months (range, 1 to 24 months). The mean migration of the proximal trochanteric osteotomy fragment prior to union was 3 mm (range, 0 to 29 mm). ETO fragment migration of >1 cm occurred in 7% (37) of the 501 hips that had radiographic analysis. Nine hips (2%) had nonunion of the ETO. Intraoperative fracture of the ETO diaphyseal fragment occurred in 22 hips (4%), postoperative fracture of the ETO diaphyseal fragment occurred in 3 hips (0.5%), and postoperative fracture of the greater trochanter occurred in 41 hips (7%). Survivorship at 10 years free of revision for aseptic femoral loosening, free of femoral or acetabular component removal or revision for any reason, and free of reoperation for any reason was 97%, 91%, and 82%, respectively.

Conclusions:
This large series of ETOs shows that the union rate is high and clinically important trochanteric migration is infrequent. The most common complications are fracture of the osteotomy fragment intraoperatively or postoperatively.

Published: December 2020

Summary
Conformance control treatment in high-temperature and ultrahigh-salinity reservoirs for easing water/gas channeling through high-permeability zones has been a great challenge. In this work, we propose a deformable microgel that can be used at more than 373.15 K and ultrahigh-salinity conditions (total dissolved solids  &gt; 200 kg/m3, Ca2+ + Mg2+ &gt; 10 kg/m3) and present a method for choosing the suitable particle size of the microgel to achieve an optimal match with the pore throat of the core. First, the particle size distribution of the microgel was analyzed to decide d50, d10, and d90 (diameter when cumulative frequency is 50, 10, and 90%, respectively). Coreflooding experiments were conducted under different permeability conditions from 20 to 900 md to investigate the migration and plugging patterns of the microgel by analyzing and fitting injection pressure curves together with the change in the morphology of the produced microgel analyzed by a microscope. The migration and plugging patterns were divided into three patterns: complete plugging; plugging—passing through in a deformation or broken state—deep migration; and inefficient plugging—smoothly passing through—stable flow. The second pattern can be further divided into three subpatterns as strong plugging, general plugging, and weak plugging. Finally, on the basis of five patterns, we build a quantitative matching relation between the particle size distribution of microgel and the pore-throat size of cores by defining three matching coefficients α = d10/d, β = d50/d, γ = d90/d (d is the average pore-throat diameter). The effectiveness of this quantitative matching relation was verified by evaluating the plugging ability (residual resistance factor) in a post-waterflooding process after the injection of 1.5 pore volume (PV) of microgel. For a strong permeability heterogeneity, the strong plugging is believed to be the expected pattern. The particles size and the pore-throat size should meet the following relationship: 1 &lt; α &lt; 2, 2 &lt; β &lt; 4, 4 &lt; γ &lt; 6. In this scenario, the deformable microgel particles could achieve both an effective plugging and a deep migration. The quantitative matching relation with multiple matching coefficients determined based on the particle size distribution might help to choose suitable particles more precisely in comparison to the method based on one matching coefficient (mostly, the ratio of the average diameter of particles to the average pore-throat diameter). In addition, the method itself to build a quantitative matching relation according to particle size distribution can be used for designing different particle-type conformance control agents for profile control and water shutoff treatment in field applications.
Stability Analysis for Severe Slugging Including Self-Lifting
Authors: de Azevedo Gabriel Romualdo , Baliño Jorge Luis , Andreolli Ivanilto 
Published: December 2020

SummaryIn this paper we investigate stability for severe slugging including self-lifting by using a stability solver. The stability solver is a tool in which a numerical linear stability analysis is applied to a mathematical model for a two-phase flow in a pipeline-riser system. The self-lifting approach is interesting because different configurations for the stationary state may occur. Depending on the system parameters, experiments show that two unstable regions may exist. Several parametric analyses are realized to evaluate the influence of self-lifting and to determine an optimal operational condition. Stability maps for severe slugging are built, and experimental data from literature are included, showing a very good agreement; in particular, the two unstable regions were satisfactorily predicted by the stability solver.
Motor Coordination in Space: An Analysis of the Effects of Microgravity on XRCCI DNA Repair Protein Function
Authors: Nagam Vishruth 
Published: December 2020

Abstract
While in space, astronauts have been known to face exposure to stressors that may increase susceptibility to DNA damage. If DNA repair proteins are defective or nonexistent, DNA mutations may accumulate, causing increasingly abnormal function as one ages [1]. The DNA single-strand break repair protein XRCC1 is important for cerebellar neurogenesis and interneuron development [2]. According to previous studies, a deficiency of XRCC1 can lead to an increase in DNA damage, in mature neurons, and ataxia (a progressive loss of motor coordination) [2]. I propose to address how XRCC1’s efficiency can change in microgravity conditions. This experiment’s relevance is underscored by the importance of motor coordination and physical fitness for astronauts; determining the potential effects of microgravity on XRCC1 is crucial for future space exploration.

Published: December 2020

Abstract
This paper describes one of the aspects of the panel method to analyze the aerodynamic characteristics of a sedan. The linear vortex panel method has been developed to simulate the ideal flow over a two-dimensional arbitrary car and, it also calculates the aerodynamic load on the body. By satisfying the boundary conditions on each control point, our linear algebraic equations are obtained. The results are sensitive to the distribution of the panels over the body thus the body is broken up equally into very small panels. After solving the set of equations, the vortices strength is obtained and the pressure distribution for the upper and the lower surface of the body is calculated. The impact of the angle of attack on the aerodynamic behavior of the intended car is investigated and it is found that the lift coefficient increases with the free stream angle from -4 to 4. The accuracy of the results has been determined by checking them against the standard CFD data. The pressure distribution trend is found very much in confirmation with the CFD results, however, a discrepancy at the rear end is observed. Therefore, it can be concluded that this method does not seem practical for geometries with steep slopes in the rear part of the car. Finally, both methods are applied to the other modified geometries with lower slopes at the rear section and the results compare well with the fluent.

Abstract
In the context of the Covid-19 pandemic in Catalonia (Spain), the first SARS-CoV-2 case confirmed was notified to the Catalonia Epidemiological Surveillance Network (RVEC) on 25 February 2020. The present study describes and analyses the respiratory samples obtained in primary care using PIDIRAC epidemiological sentinel surveillance system to complement the pandemic surveillance system activated, and describe whether SARS‑CoV-2 was circulating before the first case detected in Catalonia, between October 2019 and April 2020.During this period, 878 respiratory samples from patients with acute respiratory infection or influenza syndrome obtained by PIDIRAC epidemiological sentinel surveillance system were analysed. Of the total sample, 51.9% tested positive to influenza virus and 48.1% to other respiratory viruses, with SARS-CoV-2 being present in 6 samples. The first SARS‑CoV‑2 positive case showed the first symptoms on 2 March 2020. These were 3 men and 3 women aged between 25 and 50 years old (mean age 44.5 years old). Fever, general discomfort, coughing, chills, and arthromyalgia were the most frequent symptoms in the SARS-CoV-2 cases. Likewise, 44 samples that had tested positive for coronavirus during 2018-2019 were typed. They were all typed as one of the regular CoV, none of them being SARS-CoV-2.The acute respiratory infections sentinel surveillance system (PIDIRAC) reinforces the global epidemiological surveillance, allows to corroborate whether there is virus circulation or not, and helps confirm that generalised community transmission in Catalonia took place in mid-March.

Published: December 2020

Abstract
Scalable fabrication of high-quality thick sulfur electrodes with high-energy-density and good calendering-compatibility is a prerequisite for the practical success of metal-sulfur batteries. However, this task turns out extremely challenging due to the lack of not only advanced sulfur-rich active materials via scalable approach, but also quality-control principles for thick electrodes. Here, we first develop a new hail-inspired sulfur nanostorm (HSN) technology that can efficiently produce high-performance sulfur-rich secondary particles (S-rich SPs) with applesnail-egg-like structures. This biomimetic S-rich SPs rationally integrate critical material functions and good calendering-compatibility. Meanwhile, a concept of “healthy” microenvironment as learned from cell biology is proposed, for the first time, as a key principle revealing the critical role of calendering-compatibility in the quality-control of thick sulfur electrodes. Consequently, an ultrahigh areal capacity of 12 mAh cm− 2 @ 1 mA cm− 2 is realized. Further, we successfully demonstrate a pouch cell with an exceptional energy density of 430 Wh kg− 1 or 1,004 Wh L− 1 in a quasi-lean electrolyte condition. The technology and concept of this study may bring in new insights and general principles for design of advanced thick electrodes with, but not limited to, sulfur-based active materials.

Published: December 2020

Abstract
Background: Stereotactic navigation techniques aim to enhance treatment precision and safety in minimally invasive thermal ablation of liver tumours. We qualitatively reviewed and quantitatively summarised the available literature on procedural and clinical outcomes after stereotactic navigated ablation of malignant liver tumours.Methods: A systematic literature search was performed on procedural and clinical outcomes when using stereotactic or robotic navigation for laparoscopic or percutaneous thermal ablation. The online databases Medline, Embase and Cochrane Library were searched. Endpoints included targeting accuracy, procedural efficiency and treatment efficacy outcomes. Meta-analysis including subgroup analyses were performed.Results: Thirty-four studies (2 randomised controlled trials, 3 prospective cohort studies, 29 case series) were qualitatively analysed and 22 studies included for meta-analysis. Weighted average lateral targeting error was 3.7mm (CI 3.2,4.2), with all four comparative studies showing enhanced targeting accuracy compared to free-hand targeting. Weighted average overall complications, major complications and mortality were 11.4% (6.7, 16.1), 3.4% (2.1, 5.1) and 0.8% (0.5, 1.3). Pooled estimates of primary technique efficacy were 94% (89, 97) if assessed at 1 – 6 weeks and 90% (87, 93) if assessed at 6 – 12 weeks post ablation, with significant remaining between-study heterogeneity. Pooled odds ratio of primary technique efficacy for stereotactic versus free-hand targeting was 1.9 (1.2, 3.2)(n = 6 studies).Conclusions: Advances in stereotactic navigation technologies allow highly precise and safe tumour targeting, potentially leading to enhanced early treatment efficacy. The use of varying definitions and terminology limit comparability of safety and efficacy among studies, highlighting the crucial need for further standardization of follow-up definitions.

Abstract

There have been few reports on the kinetics of hemodialyzed (HD) patients’ immune responses in latent tuberculosis infection (LTBI). Nine cytokines and chemokines were screened through relative mRNA expression levels in whole blood samples after stimulation with Mycobacterium tuberculosis (MTB)-specific antigens from HD patients with LTBI (HD/LTBI), HD patients without LTBI, and healthy individuals and results were compared with QuantiFERON-TB Gold In-Tube (QFT-GIT) test.Only the CCL11 mRNA expression level of the HD/LTBI group was significantly higher than the other two groups (P = 0.028). CCL11 mRNA expression level of the > 0.7 IU/mL group in QFT-GIT test was significantly higher than the < 0.2 IU/mL group in QFT-GIT test and the 0.2-0.7 IU/mL group in QFT-GIT test (P = 0.0043). The present study reveals that the relative mRNA expression of CCL11 was statistically different in LTBI based on the current cut-off value (i.e., ≥ 0.35 IU/mL) and in the > 0.7 IU/mL group. These results suggest that CCL11 might be an alternative biomarker for LTBI diagnosis in HD patients.
