An Analysis of Munro’s Works from the Post-colonial Perspective
Authors: Gu Anqi 
Published: April 2022

Alice Munro is an outstanding Canadian short story writer, Nobel Prize winner in Literature for Runaway in 2013.
Most of Munro’s works are set in the remote towns of southern Ontario, highlighting unique indigenous nature of Canada. It is
noteworthy that Canada is a post-colonial country, and Munro’s works are deeply influenced by the post-colonial characteristics
of Canada. So far, domestic and foreign scholars tend to study Munro’s stories from two main aspects of narrative strategy and
feminism, but they often neglect the post-colonial nature of Munro’s writing. Therefore, starting from the post-colonial perspective,
this paper attempts to deeply explore the construction of post-colonial features reflected in Munro’s writing for the purpose of
having a deeper understanding of her works.

Authors: Wei Qiu-Shi , Li Zi-Qi , Hong Zhi-Nan , Hong Guo-Ju , Pang Feng-Xiang , Yang Peng , Yang Fan , Yuan Ying-Jia , Zhuang Zhi-Kun , He Wei 
Published: April 2022

Background:
Femoral head collapse (FHC) is associated with a poor prognosis in osteonecrosis of the femoral head (ONFH). Preserved angles (PAs), including the lateral preserved angle (LPA), the anterior preserved angle (APA) and the combined preserved angle (CPA), can be used to quantify the extent of femoral head necrosis and predict the risk of femoral head collapse. The purpose of this retrospective cohort study was to assess the efficacy of these preserved angles in the prediction of femoral head collapse using plain radiographs.

Methods:
Patients with ONFH treated conservatively between January 2010 and January 2019 were analyzed retrospectively to assess the risk of FHC. A logistic regression model was used to evaluate the independent prognostic factors associated with FHC, including age, sex, etiology, onset of symptom, The Japanese Investigation Committee classification, and PAs (LPA, APA, and CPA).

Results:
A total of 137 patients, with 180 hips, had follow-up of at least two years and were included. During the follow-up period, FHC occurred in 89 hips (49.44%) after the initial diagnosis. Multivariable analysis indicated that CPA (odds ratio [OR] = 0.95; 95%CI = 0.93-0.97; P < 0.01) was a stronger predictor of femoral head collapse compared with the Japanese Investigation Committee classification (OR = 2.40, 95%CI = 0.92-6.25; P > 0.01). The receiver operating characteristic and survival curve analyses revealed that the predictive cutoff point for the CPA was 118.7° (sensitivity = 96.70%, specificity = 79.78%, log-rank test: P < 0.01).

Conclusions:
Assessment of preserved angles on plain radiographs is a simple method to quantify the extent of lateral and anterior necrosis of the femoral head. Specifically, CPA has a potential value in predicting femoral head collapse.

Published: April 2022

Abstract
Graphene nanoribbons (GNRs) are considered one of the most promising materials for next generation electronics, however a reliable and controllable synthesis method is still lacking. Here, we report the CVD growth of GNRs on a copper surface and the corresponding mechanisms of growth. One-dimensional GNR growth is enabled by a vapor-liquid-solid (VLS) graphene growth guided by on-surface propagation of a liquid catalyst particle. Controlling the suppression of vapor-solid-solid (VSS) graphene growth along the width direction of the GNR by tuning the flow of H2 during growth gives rise to a spear head-shaped graphene that we term graphene nanospears (GNSs). The real-time visual and spatially resolved observations confirm the VSS growth of graphene can be fully suppressed and lead to GNR formation on Cu surface. These findings reveal key insight into the growth mechanism of graphene and open a door for achieving a facile and scalable method of synthesizing free standing GNRs.

Published: April 2022

Abstract
Background: Except for BRCA1/2, there is no data on the relationship between genetic counseling for the range of mutations and early-onset breast cancer populations. We looked for a link between inherited genes and the molecular subtype of early-onset breast cancer. Methods: We genotyped 1214 individuals with early-onset sporadic breast cancer (age≤40 years) who were BRCA1/2-negative in 3 genes: TP53, PALB2, and RECQL. We focus on the immunohistochemistry characteristics that are unique to each patient. Results: The mutation rates of TP53, PALB2, and RECQL in 1214 BRCA-negative young individuals were 4/1214(0.33%), 8/1214(0.66%), 2/1214(0.16%), respectively. The fact that the TP53 mutation rate was 3.49% among estrogen receptor-and/or progesterone receptor-positive, human epidermal growth factor receptor 2 (HER-2) amplification patients under the age of 35 (P<0.001) was particularly noteworthy. Conclusion: According to the findings, TP53 genetic testing should focus on women under 35 with HR-positive and HER2-positve IDC patients.

Published: April 2022

Abstract
Tetrabromobisphenol A (TBBPA) is adsorbed on sediments in river environments, and various environmental factors have distinct effects on its adsorption behaviour. Investigating the adsorption behaviour of TBBPA on the sediments in Weihe River Basin is critical for protecting the water environment and providing a theoretical basis for the prevention and control of brominated flame retardants pollution. In this study, the adsorption behaviour of TBBPA on Weihe River sediment was investigated by conducting batch equilibrium experiments, and the effects of pH, dissolved organic matter, and ionic strength on the adsorption of TBBPA were discussed. The obtained results revealed that rapid adsorption was the main mechanism of the TBBPA kinetic adsorption process. The isothermal adsorption behaviour of TBBPA was well fitted by the Langmuir model (R2 98.59%) and the Freundlich model (R2 99.21%). The adsorption capacity for TBBPA is 34.13 mg/kg. The thermodynamic results revealed that the adsorption process of TBBPA by the sediment was a spontaneous endothermic reaction. The increase in pH and ionic strength inhibited the adsorption of sediments on TBBPA. With the increase in the humic acid concentration, the adsorption of TBBPA initially increased and subsequently decreased. Synchrotron radiation-Fourier transform infrared spectroscopy indicated that the adsorption mechanism of TBBPA on the surface of sediment was mainly π–π and hydrogen bonds. The obtained results are useful for understanding of TBBPA migration and transformation in river water bodies.

Abstract
Objective The aim of this study was to investigate the mental health status and sleep quality of university students after local outbreak of COVID-19, and to help them understand the psychological stress reaction and provide base for their mental health education. Methods A cross-sectional survey was conducted on the mental health status of university students in a Wuhan-based university. Results A total of 897 university students were enrolled in the study. Compared with the epidemic period, university students' mental health status and sleep quality has a great deal of difference in the aspects of gender, grade, discipline and specialty, physical exercise, as well as with their family relationships and so on. 64.26% students would like to talk to their peers or close friends, while only 2.71% would like to call a caring hotline or seek help from a psychologist. Conclusion After the local outbreak of COVID-19 in Wuhan was contained, the mental health status and sleep quality of more than half of the students improved. However, priority attention and care should be given to female students, senior students, those undertaking literature and history majors and those dissatisfied with family relationships.

Authors: Do Kyung-Hyo , Seo Kwang-Won , Lee Wan-Kyu 
Published: April 2022

Abstract
Background: Escherichia (E.) coli causes colibacillosis in swine and humans, and is frequently associated with antimicrobial resistance. In this study we aimed to compare antimicrobial resistance, O-serogroups, virulence genes, and multi-locus sequence type of E. coli between isolates from pigs and patients suffering from diarrhea, and the most prevalent pathogenic E. coli strain from swine isolates in Korea. Methods: We tested 64 and 50 E. coli strains from pigs and patients suffering from diarrhea for antimicrobial susceptibility test, virulence genes, O-serogroups, and multi-locus sequence typing. Results: We confirmed that isolates from swine showed significantly higher resistance than from those from patients, especially to fluoroquinolone (ciprofloxacin: 37.5% and 10.0%; norfloxacin: 29.7% and 8.0%, respectively). Stx1 (23 isolates, 46.0%) was most frequently detected in patients followed by stx2 (19 isolates, 38.0%). There was no significant difference in stx2 (swine: 23.4%, patients: 38.0%). In isolates from patients, O157 (12.0%) was the most prevalent O-serogroup, and two isolates (3.1%) from pigs were confirmed to have O157. Additionally, sequence type (ST) 10 (swine: 6 isolates, patients: 2 isolates) and ST 88 (swine: 2 isolates, patients: 1 isolate) were simultaneously detected. Conclusions: We confirmed that isolates from both pigs and patients had similar virulence traits and they were phylogenetically similar. Moreover, antimicrobial resistance was significantly higher in pigs than in patients. These results suggest that there are risks for cross-infection and transfer of antimicrobial resistance between pigs and human.
Pulmonary Function Assessment of Woodworkers Exposed to Mixed Tropical Hardwood Dust in Kumasi
Authors: Ennin Isaac Ekow , Frempong Margaret Agyei , Yeboah Francis. A. , Maalman Raymond Saa-Eru 
Published: April 2022

Abstract
Background: Several studies have shown that exposed woodworkers present frequent respiratory symptoms and reduced lung volumes and airflow values including FVC, FEV1, FEV1/FVC and PEFR than controls from the general population. However, other studies have reported no significant negative health effects of wood dust on the respiratory system, no relationship between wood dust and respiratory symptoms, insignificant changes in lung function and normal FEV1 and FVC values in woodworkers compared to non-exposed controls. The effect of wood dust on the pulmonary function depends on the wood species, phytochemicals present in the wood and the concentration level of ambient air wood dust exposed to the woodworkers. The ambient air dust concentration level at the wood workshops may depend on the humidity and ventilation at the workshops. The workshops at the Sokoban Wood Village are well ventilated. This study aimed at assessing the pulmonary function of woodworkers exposed to mixed tropical hardwood in Kumasi.Method: The study was carried out among woodworkers, teachers and security men located in Kumasi. A cross-sectional, cluster and convenient sampling of 175 adult male workers were selected (86 woodworkers and 89 non-woodworkers) to participate in the study. Pulmonary function assessment was carried out using a modified version of the British Medical Research Council’s (MRC) questionnaire on respiratory symptoms and the spirometer (Alpha Vitalograph) for lung function testing. The relative humidity and the level of wood dust exposure to woodworkers were measured using the personal exposure meter (PATS+: Berkeley Air Monitoring Group). Results: The mean % relative humidity in the workshop was 67.6 and ambient air wood dust concentration ranged between (0.003 -1.02) mg/m3. The frequency of respiratory symptoms at the workplace was prevalent among the woodworkers ranging between (8-76%) (p<0.05). However, the lung volumes and airflow values were not significantly reduced in the woodworkers (p>0.05). Conclusion: The study reveals that woodworkers exposed to mixed tropical hardwood dust shows a less frequent respiratory symptoms with an insignificant reduction in the lung volumes and airflow values at the workplace due to low ambient air wood dust concentration.

Authors: Ghemari Zine , Belkhiri Salah , Saad Salah 
Published: April 2022

Abstract
A piezoelectric sensor is a sensor using the piezoelectric effect in order to measure physical quantities such as pressure, acceleration, or any other physical quantity generating stresses or mechanical deformations through active materials (magnetic, electrical, thermal, mechanical...). In this paper, the operating principle of the piezoelectric sensor is defined in detail and it is translated to mathematical model (ie the modeling of this type of sensors). This developed model is related the accelerometer electrical parameters with their mechanical parameters, and simulation of this model allows to choose the appropriate damping rate of the sensor which minimizes measurement error and improves accuracy and sensitivity of this one. The proposal of a new relation links the relative frequency by the natural frequency of the piezoelectric accelerometer makes it possible to minimize the resonance phenomenon effect, to facilitate the suitable choice of the accelerometer and to protect it.

Published: April 2022

Abstract
Background: Anemia is a major global disease burden factor linked to an adverse impact on overall prognosis and negatively affects the quality of life. There are some suggested findings for anemia on non-contrast chest CT, like relatively dense interventricular septum (septal sign) or fairly dense aortic wall (aortic ring sign). The measured attenuation value is a reproducible physical density measurement, readily obtainable from a standard CT examination. There is no reliable cut-off for blood attenuation to suggest anemia on the non-contrast chest CT. In the current study, we evaluated subjective and objective criteria' diagnostic accuracy for diagnosing anemia on unenhanced thoracic CT.Methods: Patients admitted to our academic hospital between June 2019 to March 2020 were candidates to be enrolled in this retrospective study. For the subjective assessment, the radiologists were asked to record the presence or absence of the “aortic ring sign” and “interventricular septum sign.” For the objective evaluations, blood density was measured at various anatomic locations. Results: A total of 325 patients were included in this study. There was a significant correlation between blood attenuation in all measured segments and Hb level. Subjective analysis revealed that the aortic ring sign was more sensitive than the interventricular septum sign in detecting anemia, whereas the latter character was more specific.Conclusion: The results suggest that it is possible to detect anemia from an unenhanced chest CT scan. Both objective and subjective criteria show promising sensitivity and specificity.
