The virtual flow cytometer: A new learning experience and environment for undergraduate teaching

BackgroundThe use of simulations has been steadily rising in popularity in the biosciences, not only due to the COVID-19 pandemic restricting access to physical labs and equipment but also in the face of rising student numbers. In this study, we describe the development and implementation of a novel, open-access interactive simulation used to not only supplement a laboratory class but to enhance the student learning experience. The simulation provides students with the opportunity to interact with a virtual flow cytometer, design a simple experiment and then critically analyse and interpret raw experimental data.ResultsResults showed that this highly authentic assessment used a much broader range of the mark scheme acting as an excellent discriminatory for student ability compared to simple recall as assessed by multiple-choice questions. Overall, the student response to the new assessment was positive, highlighting the novelty of the assessment, however, some students did experience technical issues when the simulation was used for the first time.ConclusionSimulations can play a crucial role in the student learning cycle by providing a rich, engaging learning environment, however, they need to be used to supplement other hands-on experiences to ensure that students acquire the necessary kinematic skills expected of a successful science graduate.

A digital smart product service system and a case study of the mining industry: MSPSS

Mining equipment products and services no longer meet the needs of future development in the mining industry due to high safety and operational risk. The deep integration of the product-service system (PSS) and digitization is required in the mining industry to promote industry transformation and safe and efficient production without changing the traditional operation mode. This paper proposes a smart product-service system for the mining industry (MSPSS) consisting of a smart product subsystem, stakeholders, smart service subsystem, and smart decision-making subsystem. The analytic hierarchy process (AHP) and virtual reality (VR) are used for decision-making, product selection, operation, and maintenance. The smart product subsystem outputs reliable digital products using three stages: digital design, virtual simulation and planning, and virtual debugging. The smart service subsystem is driven by data and digital technology and provides fault diagnosis and online maintenance services for complex mining products. A case study indicates that all stakeholders can participate seamlessly in the design process. The smart product subsystem uses iterative optimization (more than 100 iterations) to obtain the design results interactively. The smart service subsystem provides digitalized services throughout the entire process. Thus, a stable, reliable, and comprehensive product and service solution is provided for complex mining conditions. The output is used to guide the design, debugging, and operation of physical equipment. The MSPSS has higher design quality and efficiency, a shorter design time, and lower design cost (key performance indicator (KPI)) than the traditional design method.

Evaluating the Benefits of Collaborative VR Review for Maintenance Documentation and Risk Assessment

Technical documentation creation is a collaborative process involving several departments in R&D. Even though virtual reality (VR) has been demonstrated to facilitate industrial collaboration and advance the product development lifecycle in earlier studies, it has not been utilized for technical documentation review and risk assessment processes in industrial companies. This article presents a case study where the benefits of VR to maintenance documentation reviews and risk assessments were studied. The virtual reality environment was tested by nine domain experts from an industrial company in a user study that replicated their actual real-life industrial collaboration tasks. Both qualitative and quantitative data were collected during the study. Our findings show that collaborative VR has the potential to enhance the documentation review and risk assessment processes. Overall, the concept of using virtual reality for documentation review and risk assessment processes was rated positively by participants, and even though further development is needed for the review tools, VR was viewed as a concept that facilitates collaboration, enhances the current review practices, and increases spatial understanding. The benefits of VR are evident, especially for geographically scattered teams that rarely meet face-to-face or do not have access to the actual physical equipment. In cases where traditional means of communication are not enough, process improvements are needed for documentation review and risk assessment processes, and our proposed solution is VR.

Baznas Pematangsiantar has supporting and inhibiting factors in carrying out its duties as a collection and distribution of zakat. Supporting factors for Baznas Pematangsiantar, which require skilled, careful, silled workers related to zakat such as muzakki, hawl, nisab and mustahiq zakat. The inhibiting factor is that Baznas Pematangsiantar has deficiencies in physical facilities, services, capabilities, financial and operational equipment.

Applying Lightweight Deep Learning-Based Virtual Vision Sensing Technology to Realize and Develop New Media Interactive Art Installation.

The work intends to optimize the situation that interactive art devices and remote control based on traditional technology cannot meet people's actual needs to a certain extent. With the assistance of Lightweight Deep Learning (LDL) models, Interactive Artistic Installation (IAI) shows excellent creative potential in terms of dimension, space, and sense. Virtual Vision Sensing Technology (VST) explores the emotional semantics in the human-machine environment with the help of interactive art, finds the emotional interaction elements between human and machine, and promotes Human-Computer Interaction (HCI). From the perspective of the media elements of interactive art, this paper reviews the virtual VST that subverts the expression of interactive art. Then, from the perspective of artistic creation, the impact of virtual VST on IAI thinking, methods, and artistic experience is analyzed. Thereupon, a scene construction method is designed where the physical equipment is premodeled. The model is loaded in real time with visual information. The proposed method does not require complex vision and laser scanning equipment or high-configured computer systems. The proposed new media IAI model realizes the real-time loading of the scene model. According to the physical equipment dynamic information obtained by the visual data acquisition system, the proposed method can keep the virtual scene and physical models in motion synchronization. Finally, experiment results corroborate that the environment will significantly interfere with the experimental results. The training data set with boundary occlusion will be more suitable for model training and better test results (about 97% accuracy). Hence, the research content can make the Virtual Reality works have better performance, especially the sense of experience from the perspective of aesthetics. Meanwhile, it also enriches the research theory in the field of new media art installation technology.

Assessment of the Motor Competencies Regarding Adapted Physical Activities

In the introduction, part authors give some of the histories of assessment in Adapted Physical Education (APE). There are currently 13 legally recognized disabilities. Inclusion has many meanings, but typically it is linked to the quality of life in the least restrictive environment and social competence, which is in line with the attitudes of individuals with and without disabilities. The fundamental principle of valuing diversity guides inclusion. Belonging, acceptance, and a sense of being supported are essentials of an inclusive environment. The most prevalent barriers to including students with disabilities are teacher preparation and teacher attitudes and perceived barriers to instruction consisting of equipment, programming, and time. Inclusion may impact internal and external factors, controlled and uncontrolled, and active and passive. People of all ages, types of disabilities, and experiences demonstrate individual differences in responding when facing similar situations in movement settings. An inclusive environment offers all individuals equally interesting, equally important, and similarly engaging tasks. An inclusive environment comprises the physical space and equipment, the social-emotional atmosphere, and the teaching strategies that are in use. The physical space should be barrier-free and include various equipment related to the lesson/activity. The social-emotional atmosphere should be free of stress, underlining cooperation rather than the existence of the fittest, fastest, or strongest. Teaching strategies should incorporate techniques that promote collaboration between instructor and learners, respond to different learning styles, encourage self-responsibility, provide opportunities for independent learning, and use various informal assessment tools to guide instruction.

Flood Control Measures in One Municipality in Camarines Sur, Philippines: Bases for Community-Based Flood Control Interventions

Hydrometeorological hazards like flooding are inevitable; these affect agriculture and impact the economy for a prolonged duration. This research study was conducted to determine and assess the flood control measures in the municipality of Nabua in the Province of Camarines Sur, Philippines as bases for developing community-based flood control interventions. Using the descriptive evaluative survey method with a validated questionnaire as the primary data gathering instrument, gathered data were computed, tabulated, analyzed, and interpreted. It has shown that the degree of implementation of the flood control measures is high for structural and non-structural flood management. The null hypothesis is rejected. The difference between the responses of the respondents was significant. The extent of the effect of the factors directly influences the implementation of the flood control measures. It can be concluded that the Municipality of Nabua controls flooding primarily through its flood control infrastructures that are strategically situated in the municipality, human resources, and collaboration and linkages. Moreover, the responses of the respondents are significantly different. Improvement and upgrading of its physical facilities and equipment to acquire real-time information; intensifying its campaign and information drive to build a more vital link between the municipality and its constituents, and information dissemination using social media and communications technology can increase awareness, mitigation, control, and response to flooding are thereby recommended. The community-based interventions on flood control can serve as a guide and an eye-opener for the local government unit of Nabua to promulgate and enact municipal ordinances about flood control.

Design of Platforms for Experimentation in Industrial Cybersecurity

The connectivity advances in industrial control systems have also increased the possibility of cyberattacks in industry. Thus, security becomes crucial in critical infrastructures, whose services are considered essential in fields such as manufacturing, energy or public health. Although theoretical and formal approaches are often proposed to advance in the field of industrial cybersecurity, more experimental efforts in realistic scenarios are needed to understand the impact of incidents, assess security technologies or provide training. In this paper, an approach for cybersecurity experimentation is proposed for several industrial areas. Aiming at a high degree of flexibility, the Critical Infrastructure Cybersecurity Laboratory (CICLab) is designed to integrate both real physical equipment with computing and networking infrastructure. It provides a platform for performing security experiments in control systems of diverse sectors such as industry, energy and building management. They allow researchers to perform security experimentation in realistic environments using a wide variety of technologies that are common in these control systems, as well as in the protection or security analysis of industrial networks. Furthermore, educational developments can be made to meet the growing demand of security-related professionals.

The majority of the teachers who received the certificate of merit also stated that the reward did not provide any benefits apart from some partial financial gain. Moreover, they expressed that they were motivated more after receiving the certificate. All teachers agreed that the certificate of merit should be rewarded, and they are supported by the opinions of school administrators in this regard. Overall, the participants emphasized that there should be clear criteria and fair practice in the process of rewarding the certificate of merit.

Avaliação de custos para implementação de uma central de misturas intravenosas em um hospital da fronteira sudoeste do Brasil

Objective: The objective of this study was to evaluate the cost for the implementation of an intravenous medication mixing center (CMI) in a philanthropic hospital on the southwestern border of Brazil. Methods: A survey of the costs of equipment, furniture, utensils and human resources required by the current legislation for the implementation of the CMI was carried out. In addition, an analysis of prescriptions was performed from hospitalized patients in Adult (UTI-AD) and Neonatal (UTI-NEO) Intensive Care Units (July to December/2020) who used injectable drugs. The costs of those medication and of losses for leftover medication were estimated. Seven drugs/mixtures were then selected as a proposal to carry out a pilot test for the implementation of the CMI. Results: The costs involving the physical area, furniture, equipment and materials were estimated at US$ 10,446.52. It is also estimated that it would be necessary to employ at least 2 pharmacists, 4 pharmacy assistants and 2 more students, with monthly costs calculated around US$ 2,267.80, excluding labor charges. The estimated total cost of intravenous drugs, solutions and materials to meet medical prescriptions for the 169 patients included in the study was US$ 24,748.13. Considering that the hospital does not have a CMI to centralize the preparation of unit doses of injectable drugs, a total loss of medication leftovers was estimated at approximately US$ 7,764.64. For pilot testing, the following preparations were suggested: omeprazole, heparin, midazolam and insulin (UTI-AD), electrolyte solutions, ampicillin and gentamicin (UTI-NEO). Conclusion: Although the implementation of a CMI requires significant resources, it would provide greater patient safety and an estimated savings of 31.4% with injectable drugs costs.

Análise da adequação estrutural das maternidades do Piauí, Brasil, 2018-2019

Abstract Objectives: to evaluate the structure and adequacy of maternal healthcare facilities in Piauí. Methods: cross-sectional study in 26 hospitals with more than 200 births/year between 2018-2019. The structure was assessed by direct observation and interview with manager, in four domains: physical aspects, human resources, equipment, and drugs. Fisher’s chi-square/exact tests were used to assess differences in adequacy of structure. Results: only 46.2% of the maternal healthcare facilities had pre-delivery, parturition and immediate post-partum room. Pediatricians (73.1%) and anesthesiologists (61.5%) were the least present professionals on-duty regime. Regarding drugs, magnesium sulfate and oxytocin were observed in 76.9% of hospitals. Overall adequacy was 23.1%, being higher in maternal healthcare facilities in the capital (p=0.034) and in private ones (p=0.031). Conclusions: Data show inequalities in the structure of maternity hospitals of the state. The absence of health professionals, essential drugs, and appropriate physical structure can expose women and newborns to unnecessary and avoidable risks.

Using customizable simulation models of high voltage electrical circuits in educational process

In the modern world, the issue of the use of digital technologies in the framework of teaching students in technical specialties is relevant. For a number of reasons, the solution of this issue is particularly important when preparing for training areas related to the electric power industry and high-voltage equipment. Software products that allow to carry out simulation modeling of technical systems are among the most accessible types of digital technologies used in higher educational institutions of Russia. When conducting classes on the study of transients in electrical circuits or electric drive control systems, students can use specialized software and build simulation models in the absence of real physical equipment. The paper assesses the need for training in the creation and use of simulation models of devices used in conducting high-voltage tests (using the example of a generator capable of realizing a high voltage of a given shape), as well as models of control systems of electric drives. An additional advantage contributing to the use of such schemes in teaching students is that the result of their work are the values of physical parameters presented in numerical form, which allows the developed models to be used as blocks or libraries for the implementation of larger-scale projects.

Thinglink and the Laboratory: Interactive Simulations of Analytical Instrumentation for HE Science Curricula

Access to laboratory facilities and associated instrumentation represents a major barrier to learning in physical science education, due to constraints introduced by limited time and financial resources, cost of acquisition, and health and safety requirements. Virtualized laboratories offer some mitigation of these problems but may also introduce further problems such as limiting discussion and collaboration, inhibiting development of physical skills, and reducing engagement. This study aims to evaluate the effectiveness of virtual simulations of analytical instruments for applied science student learning and teaching. Two virtual instruments (X-ray fluorescence spectrometer (XRF) and an ion chromatography system (IC)) were assembled on the Thinglink online virtual platform, with background theory, detailed animated instructions, and simulated data collection capabilities. The two simulations were disseminated to teachers and learners, with subsequent feedback gathered via questionnaires and four one-to-one interviews. Results showed that feedback was extremely positive from all users, with many expressing excitement for the accessibility and inclusivity implications and the freedom to engage asynchronously. Users found them to be high quality, highly accessible, and inclusive resources but generally felt that their application as supporting information would have greater benefit than using them in a standalone fashion. The most prominent concern was the time required to create materials. Study implications suggest that the style of online virtual learning resource presented here is viewed as beneficial by learners and teachers alike, if planned to be as efficient as possible and delivered as a supplement to physical equipment learning. The application of additional online resources to broader groups should be the subject of further investigation, with the potential benefits for academic performance being of utmost importance.

Extending the Brick schema to represent metadata of occupants

Energy-related behaviors of occupants constitute a key factor influencing building performance; accordingly, the measured occupant data can support the objective assessment of the indoor environment and energy performance of buildings, which can inform building design and operational decisions. Existing data schemas focus on metadata of sensors, meters, physical equipment, and IoT devices in buildings; however, they are limited in representing the metadata of occupant data, including occupants' presence in spaces, movement between spaces, interactions with building systems or IoT devices, and preference of indoor environmental needs. To address this gap, an extension to the widely adopted metadata schema, Brick, is proposed to represent the contextual, behavioral, and demographic information of occupants. The proposed extension includes four parts: (1) a new “Occupant” class to represent occupants' demography and energy related behavioral patterns, (2) new subclasses under the Equipment class to represent envelope system and personal thermal comfort devices, (3) new subclasses under the Point class to represent occupant sensing and status, and (4) new auxiliary properties for occupant interactable equipment to represent the level of controllability for each piece of equipment by occupants. The extension is implemented in the Brick schema and has been tested using multiple occupant datasets from the ASHRAE Global Occupant Database. The extension enables Brick schema to capture diverse types of occupant sensing data and their metadata for FAIR data research and applications.

Role of Superoxide Dismutase in Amyotrophic Lateral Sclerosis

Amyotrophic Lateral Sclerosis (ALS), or Lou Gehrig's disease, is an adult‐onset neurodegenerative disorder that has been linked to over 200 mutations from the SOD1 gene. The protein created from this gene is superoxide dismutase (SOD1), an enzyme responsible for breaking down toxic superoxide radicals by facilitating the binding to zinc and copper. Superoxide dismutase is a homodimer, composed of two identical subunits, and is located in the cytoplasm of the cell, Each subunit has 154 amino acid residues with a β‐barrel core, formed by 8 beta‐sheets, and three outer loops which are linked together by a disulfide bond, a hydrogen bond network, and a metal‐binding site for both zinc and copper. This metal‐binding site is responsible for the catalyzation of superoxide radicals to hydrogen peroxide and dioxygen. The redox reactions that SOD1 allows to occur are the oxidation of superoxide to dioxygen and the reduction of superoxide to hydrogen peroxide while alternating the oxidation states of Copper. The zinc molecule acts as a structural element for the reaction. The catalyzation of superoxide radicals to safer components occurs because the accumulation of superoxide radicals is toxic to the cell, and can lead to cell death. Another role of SOD1 is its responsibility in preventing oxidative stress. Oxidative stress is the result of the imbalance between reactive oxygen species such as superoxide, and the activity of superoxide dismutase to detoxify the affected areas. In cases of ALS, mutations cause this accumulation, which leads to motor neuron death. The most common mutation of SOD1 in the United States, as well as the one that causes the fastest onset for ALS to occur, is A5V, which is the replacement of the alanine residue with valine at position 5. This mutation can result in not only the accumulation of superoxide radicals but also the production of more neurotoxic radicals and fibrillar aggregates of misfolded SOD1, which can occur due to the absence of the disulfide bond or bound zinc ions. These effects lead to motor neuron death, which manifests as the symptoms of ALS. The symptoms of ALS are progressive muscle weakness, loss of voluntary muscle control, the decline of the ability to initiate movement, and paralysis. ALS, especially as a result of the A5V mutation, often leads to a shorter life expectancy. Amyotrophic Lateral Sclerosis currently has no cure, but there are many evolving therapies for the disease. Patients with ALS are encouraged to participate in gentle, low‐impact physical therapies and use special equipment to support communication, nutrition, and breathing. The drugs approved by the FDA to help treat ALS include Riluzole (Rilutek), which reduces damage to cells by blocking the release of glutamate, and Edaravone (Radicava) which removes free radicals. In addition, small‐molecule therapies are being developed to stabilize the native form of SOD1 in the absence of zinc or in the presence of protein mutations, which may reduce the effects of the manifestation of the disease. Further research is needed to determine specifically how mutations of SOD1 lead to motor neuron death, and the resulting symptoms of Amyotrophic Lateral Sclerosis.

Intelligent Home Automation Using IoT

Abstract: When it comes to automation and smart homes, the Internet of Things (IoT) is a crucial idea in today's world. It has to do with the automation of things through computing, in which all things and physical devices can be connected in order to make them sentient and programmable so that they can interact with humans. IoT is a cloud computing network that allows users to access physical objects or control equipment over a wireless network from any distance, at any time and in any location. One example of IoT technology is smart home automation. The usage of IoT in smart home automation was completely adopted in the twenty-first century, according to this study, by guaranteeing that household appliances and equipment were connected. This sort of IoT design not only controls devices, but also stores sensor data in the cloud and acts on it. The cloud is used to deliver sensor data via Wi-Fi module, and then a decision tree is applied to determine the output of the electronic devices. IoT-based services help to improve the domestic environment and are utilised for a variety of purposes. IoT applications based on home automation are flexible and widely used. This provides access to specific data in the house as well as the ability to control various parameters remotely. This article details the entire architecture of a smart home automation system based on IoT sensing and monitoring. The suggested smart home automation system prototype is constructed and tested on hardware in this project, allowing the user to control a limited number of household appliances using the bylnk application. The NodeMCU (ESP8266) microcontroller is used, and communication between the microcontroller and the application is done using Wi-Fi (Internet).

Asynchronous industrial collaboration: How virtual reality and virtual tools aid the process of maintenance method development and documentation creation

In the light of Industry 4.0, the field of Industrial Maintenance faces a large digital transformation, adopting Extended Reality (XR) technologies to aid industrial operations. For the manufacturing corporations that provide maintenance services, the efficiency of industrial maintenance plays a crucial role in the competitiveness and is tightly related to the technical documentation supporting maintenance. However, the process of documentation creation faces several challenges due to lack of access to the physical equipment and difficulties in remote communication between globally distributed departments. To address these shortcomings, this research investigates the utilization of Virtual Reality (VR) to facilitate asynchronous collaboration of globally dispersed departments involved in the pipeline of maintenance method and documentation creation. The presented proof-of-concept (the COVE-VR platform) has been developed as an academia-industry collaboration and evaluated iteratively with subject matter experts. The proposed VR platform consists of two virtual environments and eight virtual tools, which allow interaction with virtual prototypes (3D CAD models) and means of digital content creation. Our findings show the high relevance of the developed solution for the needs of industrial departments and the ability to support asynchronous collaboration among them. This article delivers qualitative findings on the value of VR technology and presents guidelines on how to develop virtual tools for digital content creation within VR, adaptable to other industrial contexts. We suggest providing embedded guidance and design consistency to ensure smooth interactions with virtual tools and further discuss the importance of proper positioning, the transparency of operations and the information property of generated content.
