Effect of Graphene Addition on Polycaprolactone Scaffolds Fabricated Using Melt-Electrowriting

Melt-electrowriting (MEW) is an emerging method that combines electrospinning and extrusion printing, allowing the fabrication of micron-scale structures suitable for tissue engineering. Compared to other additive fabrication methods, melt-electro written structures can offer more appropriate substrates for cell culture due to filament size and mechanical characteristics of the fabricated scaffolds. In this study, polycaprolactone (PCL)/graphene composites were investigated for fabrication of micron-size scaffolds through MEW. It was demonstrated that the addition of graphene can considerably improve the processability of PCL to fabricate micron-scale scaffolds with enhanced resolution. The tensile strength of the scaffold prepared from PCL/graphene composite (with only 0.5 wt.% graphene) was proved significantly (by more than 270%), better than that of the pristine PCL scaffold. Furthermore, graphene was demonstrated to be a suitable material for tailoring the degradation process to avoid undesirable bulk degradation, rapid mass loss and damage to the internal matrix of the polymer. The findings of this study offer a promising route for the fabrication of high-resolution scaffolds with micron-scale resolution for tissue engineering.

Laporan Keuangan Perspektif SIRI

In order to provide information and make choices, financial reports are delivered to relevant parties. However, because there are so many parties interested in the financial accounts, there is a lot of information asymmetry in the process of presenting them. In order for the information to be used as a firm foundation for internal and external parties, a new perspective is required in the process of presenting financial statements. In order to interpret the meaning of the SIRI perspective financial statements, this study used a qualitative method that was supplemented by a literature review. So that a conclusion regarding the presentation of fresh financial statements can be formed. The findings of this study offer a framework for presenting financial statements from four different perspectives: spiritual Integrity, Reso', and ininnawa. With the goal that these four viewpoints will influence the way financial statements are presented. And, in the future, bring benefits to both internal and external parties.

Weather Forecast Semiotics: Public Interpretation of Common Weather Icons

Weather icons are some of the most frequently used visual tools meteorologists employ to communicate weather information. Previous research has shown a tendency for the public to make inferences about weather forecast information based on the icon shown. For example, people may infer a higher likelihood of precipitation, assume a higher intensity of precipitation, or determine the duration of expected precipitation if the weather icon appears to show heavy rain. It is unknown to what extent these inferences align with what the meteorologist who chose the icon intended to convey. However, previous studies have used simulated weather icons rather than ones currently in use. The goal of our study was to explore how members of the public interpret actual weather icons they see on television or in mobile applications. An online survey distributed by broadcast meteorologists through social media was used to collect 6,253 responses between August and September of 2020. Eleven weather icons currently used by broadcast meteorologists were included in the study. We also tested eight common weather phrases and asked people whether they thought the icons were good illustrators of those phrases. Additionally, people were asked to assign a probability of precipitation (PoP) to the icons. The findings of our study offer new and unique insights that will improve the communication of weather information by giving meteorologists information about how their audiences interpret weather icons.

No Campus Life for Us: Personal Reflections of First-Year Students at a Malaysian University

The purpose of this qualitative study was to look into the online learning experiences of first-year communication and media students. The study was conducted by gathering 45 written reflection papers from first-year undergraduate students covering their opinions, challenges, and feelings about online learning. NVivo 12 was used to analyse the contents of these reflection papers. The findings of this reflective narrative study offer valuable insights into how first-year communication and media students perceive online learning classes in higher education, the challenges of working with new virtual classmates, the adjustment and role as student and daughters at home, as well as their mental health and emotional feelings towards online learning. Students learned vital lessons about time management, environmental awareness and independence as a result of these experiences. Students experienced anxiety and were demotivated as a result of the lack of face-to-face interaction and effective self-introduction with new peers. Most importantly, they were dissatisfied because they had lost out on the experiences of living on campus during their first year of study. Furthermore, this research looked into another component of the qualitative technique, which is a reflective method to study the first-year students’ experiences with online learning in a Malaysian public university, an insight that can be useful for both lecturers and students.

A CFD study on the evaporative cooling of a water droplet located in a duct

The current numerical study aimed for analayzing heat transfer of a spherical water droplet placed in a rectangular duct. The problem particularly deals with air-cooling of the droplet. The computational fluid dynamic technique is used to treat the problem. In order to study the problem, the effect of evaporation on the droplet's heat transfer is taken into consideration to make the problem more realistic. Moreover, various parameters like the inlet velocity and the temperature of the upstream are numerically checked. It is found out that with involving evaporation, the mean temperature of the droplets increases in comparison with the case that there is no evaporation involved. The outcomes of the current study offer useful and deep insight into the evaporative cooling of a water droplet.

Findings highlighted three main themes: Balancing priorities, Fear of failure, and Critical incidents. These themes are discussed in terms of possible risk factors contributing to students experiencing anxiety while at university. Findings together with recommendations listed in this study offer higher education staff and institutions the opportunity to explore areas of focus and improve university students’ mental health.

Effects of various artificial agarwood-induction techniques on the metabolome of Aquilaria sinensis

Background Agarwood is a highly sought-after resinous wood for uses in medicine, incense, and perfume production. To overcome challenges associated with agarwood production in Aquilaria sinensis, several artificial agarwood-induction treatments have been developed. However, the effects of these techniques on the metabolome of the treated wood samples are unknown. Therefore, the present study was conducted to evaluate the effects of four treatments: fire drill treatment (F), fire drill + brine treatment (FS), cold drill treatment (D) and cold drill + brine treatment (DS)) on ethanol-extracted oil content and metabolome profiles of treated wood samples from A. sinensis. Results The ethanol-extracted oil content obtained from the four treatments differed significantly (F < D < DS < FS). A total of 712 metabolites composed mostly of alkaloids, amino acids and derivatives, flavonoids, lipids, phenolic acids, organic acids, nucleotides and derivatives, and terpenoids were detected. In pairwise comparisons, 302, 155, 271 and 363 differentially accumulated metabolites (DAM) were detected in F_vs_FS, D_vs_DS, F_vs_D and FS_vs_DS, respectively. The DAMs were enriched in flavonoid/flavone and flavonol biosynthesis, sesquiterpenoid and triterpenoid biosynthesis. Generally, addition of brine to either fire or cold drill treatments reduced the abundance of most of the metabolites. Conclusion The results from this study offer valuable insights into synthetically-induced agarwood production in A. sinensis.

MMS Observation of the Hall Field in an Asymmetric Magnetic Reconnection with Guide Field

In this paper, we investigate the structure of out-of-plane magnetic field in the reconnection event observed by Magnetospheric Multiscale Mission at the magnetopause of the Earth magnetosphere on 2015 October 21. We find that the perturbation of out-of-plane magnetic field in this event is different from previous observations of the quadrupolar Hall magnetic field. The distinct out-of-plane magnetic field is interpreted as a part of the hexapolar Hall magnetic field obtained in a recent simulation of asymmetric reconnection with the guide field. This is significant evidence of hexapolar Hall magnetic field in collisionless magnetic reconnection from the observations in the magnetosphere. High-resolution measurements of particle and field are used to provide a comprehensive description of the features of the hexapolar Hall magnetic field. The results from this study offer an insight into the Hall effect in collisionless magnetic reconnection.
