Published: March 2023

This paper presents the hardware and control software architectures of an intelligent humanoid robot. The robot has a mobile base consists of three omnidirectional wheels that allows it to move freely with three degree-of-freedom (DOF), two 6-DOF arms and 3-DOF neck and head that allows it to perform most of the common movements of human. Detail hardware components are given to show our mechanical design solution of the robot. The control software structure of the robotic system is constructed in the robot operating system (ROS) framework which is mainly used as a bridge to connect the control modules and various peripheral devices to ease our robot system task management. We have also shown the detail structure of the robot control system which consists of all key control modules which enable the robot functions: from upper level with AI-based techniques such as image and sound processing to middle level with the robot motion controllers and then to the lower level with the management of atuators and sensors. The proposed architecture is being developed and tested on a real humanoid robot prototype called Bonbon to support Enghlish teaching in elementary schools.

AbstractCement is the strength-forming component of concrete. It has been a major building material for more than a century. However, its production is accountable for a considerable percentage of global CO2 emissions and is very energy-intensive. The Ordinary Portland Cement (OPC) production is a thermal process at around 1450 °C. This study shows that the reactivation of Hydrated Cement Powder (HCP) can be successful at a much lower temperature. Therefore, the possibility of using HCP to replace parts of OPC in concrete reduces the energy consumption and the CO2 emissions associated with OPC production. HCP, which may ultimately stem from recycled concrete, needs treatment to produce new concrete of the required mechanical strength. Using reactivated HCP in concrete, an optimum strength is achieved by heating the HCP in the range of 400–800 °C. Among other factors, the type of cement used influences the optimum heating temperature and attainable strength. This paper shows that 600 °C is an optimum heating temperature using the OPC type CEM I 52.5R. The crystalline phase transitions resulting from the thermal treatment were analyzed by X-ray diffraction (XRD), differential scanning calorimetry (DSC), and thermogravimetry (TG). The heat released during hydration was investigated, and scanning electron microscopy (SEM) displays the microstructure evolution. OPC can be partially replaced by thermally treated HCP in mortar, attaining similar mechanical strength values.

Background: Type 2 Diabetes (T2D) is associated with coronary microvascular dysfunction, which is thought to contribute to compromised diastolic function, ultimately culminating in heart failure with preserved ejection fraction (HFpEF). The molecular mechanisms remain incompletely understood, and no early diagnostics are available. We sought to gain insight into biomarkers and potential mechanisms of microvascular dysfunction in obese mice (db/db) and lean rats (Goto-Kakizaki) pre-clinical models of T2D-associated diastolic dysfunction. Methods: The microRNA (miRNA) content of circulating Extracellular Vesicles (EVs) was assessed in T2D models to identify biomarkers of coronary microvascular dysfunction/rarefaction. The potential source of circulating EV-encapsulated miRNAs was determined, and the mechanisms of induction and the function of candidate miRNAs were assessed in Endothelial Cells (ECs). Results: We found an increase in miR-30d-5p and miR-30e-5p in circulating EVs that coincided with indices of coronary microvascular EC dysfunction (i.e., markers of oxidative stress, DNA damage/senescence) and rarefaction, and preceded echocardiographic evidence of diastolic dysfunction. These miRNAs may serve as biomarkers of coronary microvascular dysfunction as they are upregulated in ECs of the left ventricle of the heart, but not other organs, in db/db mice. Furthermore, the miR-30 family is secreted in EVs from senescent ECs in culture, and ECs with senescent-like characteristics are present in the db/db heart. Assessment of miR-30 target pathways revealed a network of genes involved in fatty acid biosynthesis and metabolism. Over-expression of miR-30e in cultured ECs increased fatty acid β-oxidation and the production of reactive oxygen species and lipid peroxidation while inhibiting the miR-30 family decreased fatty acid β-oxidation. Additionally, miR-30e over-expression synergized with fatty acid exposure to down-regulate the expression of eNOS, a key regulator of microvascular and cardiomyocyte function. Finally, the knock-down of the miR-30 family in db/db mice decreased markers of oxidative stress and DNA damage/senescence in the microvascular endothelium. Conclusion: MiR-30d/e represents early biomarkers and potential therapeutic targets that are indicative of the development of diastolic dysfunction and may reflect altered EC fatty acid metabolism and microvascular dysfunction in the diabetic heart.

The COVID-19 pandemic provokes higher learning institutions to initiate an agile yet well-planned response in ensuring quality online teaching and learning. In response to the challenges of transitioning from the traditional to online teaching and learning, the researchers explored the lessons uncovered from the (e)mergency Remote Instructional Skills Enhancement (e-RISE), an intervention that comprised series of faculty mentoring sessions towards full adoption of an online platform for professional nursing courses. This action research utilized the Look, Think, Act cycle of Stringer (1996) involving eleven nurse faculty as participants. Using thematic analysis in data treatment, various themes were revealed ranging from advancing technological knowledge and competence to accepting personal limitations, values acquisition, and teacher empowerment. The technological knowledge and competence of the nurse faculty require further improvement. The acceptance of personal limitations in terms of putting up online learning modules implies the need to enhance pedagogy and design. Values acquisition in terms of life skills were dominant in response to the needs to change and adapt. Reverse mentoring is also recommended as this is paramount towards the success of the Project e-RISE. Lastly, teacher empowerment is touted essential to make remote teaching and learning more feasible, effective and efficient. The study findings suggest that Project e-RISE be adopted as a sustainable mechanism to capacitate nurse faculty in their migration from traditional to remote or online teaching.

Published: March 2023

Inflammation is a complex series of changes in tissue due to tissue injury caused by bacteria, trauma, chemicals, heat, and pain. Gamboge (Garcinia xanthochymus) is a fruit-bearing tree native to Southeast Asia. Plants of the genus garcinia are rich in secondary metabolites such as flavonoids, steroids, and triterpenes which have potential pharmacological activity. This study aimed to determine the anti-inflammatory activity based on the reduction in edema volume of Gamboge (Garcinia xanthochymus) stem bark. The inquiry was experimental. Through maceration, an ethanol extract of the gamboge stem was created. The animals were divided into five groups, each containing five white male rats. The test given was a suspension of gamboge ethanol extract at doses of 200, 400, and 600 mg/kgBW, a negative control of 1% Na CMC suspension, and a positive control of 2.25 mg/kgBW sodium diclofenac. Observations were made for 6 hours, and then data were analyzed using a two-way analysis of variance (ANOVA) test. The results showed that gamboge ethanolic extract was proven to have an anti-inflammatory effect in white male rats induced by carrageenan starting at doses of 200, 400, and 600 mg/kgBW, marked by a significant difference to the negative control (p<0.05). The 600mg/kgBW dose group showed no significantly different results from the positive control group (p>.05). These results concluded that the dose group 600mg/kgBW was the best dose of gamboge stem ethanol extract had an anti-inflammatory activity based on reducing the volume of leg edema of white male rats.

Published: March 2023

Summary
Hydraulic fracturing is one of the important stimulation methods to enhance the productivity of coalbed methane (CBM) wells. However, the commonly used water-based fracturing fluids can bring some bottlenecks such as large amount of water consumption, clay-mineral swelling, and poor fracturing performance on ductile coals. Cyclic liquid nitrogen (LN2) fracturing, as a novel nonaqueous stimulation method, has the potential to solve the above problems. In cyclic LN2 fracturing, supercooling LN2 is injected in a cyclic manner [i.e., alternating high injection rate (or pressure) and low injection rate (or pressure)]. Coals will be subjected to cyclic freeze-thaw, stress oscillation, and fatigue damage, which is expected to improve the stimulated reservoir volume. First, laboratory cyclic LN2 fracturing tests were conducted on coal samples with various coal ranks to investigate the fracture initiation/propagation behavior and fracture network patterns. Cyclic water fracturing tests were also conducted as comparisons. Then, computed tomography (CT) scanning and geomechanical/petrophysical properties tests before and after LN2 fracturing were performed to assist in understanding the cyclic LN2 fracturing mechanisms and implications. Finally, to solve the field application concerns, we investigated the possible fracture geometries at the field scale, temperature distribution of LN2 along the wellbore during injection, and the economic feasibility. The key factors affecting the temperature distribution during LN2 transportation along the wellbore were clarified for the first time. The results indicate that cyclic LN2 fracturing shows the potential to decrease the breakdown pressure and produce complex fracture networks. Different coal ranks have different responses to cyclic LN2 fracturing attributed to the variances in natural fracture development and geomechanical/petrophysical properties. Besides, increasing the cycle number is effective in enhancing the cyclic LN2 fracturing performance on coals with relatively higher geomechanical strengths and tighter rock mass. The suggested cycle numbers from low to high for different coal ranks are listed here: low-rank coal &lt; high-rank coal &lt; middle-rank coal. In field applications, gaseous nitrogen (N2) can be used as the annulus fluid to provide an effective insulation for heat transfer between the low-temperature LN2 and the surrounding environment. In addition, the net present value (NPV) analysis indicates that LN2 fracturing is an economically feasible stimulation method, which can exceed slickwater fracturing in some cases. The key findings are expected to provide preliminary insights into the potential field applications of cyclic LN2 fracturing in CBM or other unconventional oil/gas exploitation.

Abstract

Background: Suicide is an important health issue, nearly all over the world. Columbia suicide severity rating scale (C-SSRS) is a well-known instrument for suicide risk assessment. Our purpose in this study is to provide a Persian version of C-SSRS and evaluate its psychometric properties in Iranian military population, particularly suicide risk leveling characteristic of C-SSRS.Material & method: for linguistic adaptation, we gathered opinions of expert panel, including 23 professionals in mental health sciences. Furthermore, this version was employed in two groups of soldiers, one of them a sample of normal population (N=338) and the other a sample of clinical population from a referral psychiatric hospital (N=348). Beside the C-SSRS, Beck Scale for Suicidal Ideation (BSSI), Beck hopelessness scale (BSS) and general health questionnaire 28 (GHQ28) was obtained from the participants. Correlation coefficient, internal consistency and factor analysis was evaluated, using Statistical Package for the Social Sciences (version 23) software.Results: all items of Persian version of C-SSRS had acceptable content validity and face validity. This tool had high correlation coefficient with BSSI (r=0.73, P<0.001)and BHS (r=0.64, p<0.001) but low CC with GHQ28 (r=0.22, p<0.001). especially, suicide risk level based on C-SSRS had high correlation with BSSI and BHS. Also, its internal consistency was satisfactory (Cronbach's alpha=0.89). And finally, factor analysis, two factors were obtained that is consistent with suicidal ideation and suicidal behavior factor.Conclusion: our results indicated acceptable validity and reliability for Persian version of C-SSRS and capability of this instrument in classifying the suicide risk. It could be concluded that ordinal suicide risk level (as red, orange, yellow and green) is a valid index for application of C-SSRS.

Abstract

Microplastics (MPs) are widespread pollutants of emerging concern, and the risks associated with their ingestion have been reported in many organisms. Terrestrial environments can be contaminated with MPs, and terrestrial organisms, including arthropods, are predisposed to the risk of ingesting MPs. In the current study, the larvae of the paper wasp Polistes satan were fed two different doses (6 mg or 16 mg at once) of polystyrene MPs (1.43 mm maximum length), and the effects of these treatments on immature development and survival till adult emergence were studied. Ingestion of the two doses resulted in mortality due to impaired defecation prior to pupation. The survival of larvae that ingested 16 mg of MPs was significantly lower than that of the control. The ingestion of 16 mg of MPs also reduced the adult emergence (11.4%) in comparison to the control (44.4%). MPs were not transferred from the larvae to the adults that survived. These findings demonstrate that MP ingestion can be detrimental to P. satan, e.g. larval mortality can decrease colony productivity and thus the worker force, and that MPs can potentially affect natural enemies that occur in crops, such as predatory social wasps.

Published: March 2023

Abstract
Background: To classify and analyze the risk factors associated with initial noninvasive prenatal testing (NIPT) failure in the context of pregnancy outcomes.
Methods: From May 2019 to April 2022, 30039 singleton pregnant women were enrolled in the NIPT, for whom initial failure samples were analyzed and followed up. The initial and final test failure rates were determined. The risk factors of initial test failure were classified as follows: the repeat test success rate and positive predictive values (PPVs) of “z-score in gray area” samples were analyzed; the difference between cases with initial “low fetal fraction (FF)” result and initial “low risk” result, the key factors for success in the second test, and the effect of experimental conditions on the detection rate of low FF samples were assessed; the final NIPT results and pregnancy outcomes of samples with “quality control (QC) failure” were followed up and evaluated.
Results: The total initial failure rate and final failure rate were 2.7% and 0.12% respectively. 99.04% of “z-score in gray area” samples obtained results after repeated test. Of the 22 cases with abnormal or no results, only 15 cases conducted prenatal diagnosis none of which revealed abnormalities with clear clinical significance. Body mass index (BMI), gestational age, library concentration, and fetal sex were considered risk factors for initial low FF results, but were not critical for the success of the second test, or even for initial fetal concentration. The incidence of low FF samples was more frequent with G-type blood collection tubes than with K-type tubes. A total of 99.22% of the QC failure samples obtained interpretable results after resampling or library reconstruction, and all were at low risk.
Conclusions: NIPT has a low final failure rate, but the initial failure rate warrants attention. The PPV of the initial gray area samples was low. Maternal BMI, gestational age, library concentration, fetal sex, and type of blood collection tube may be risk factors for “low FF”.
