Oxymoroning Education: A Poem about Actualizing Affect for Public Good

An oxymoron is a self-contradicting or incongruous word or group of words as in Lord Byron’s (1788–1824) line from his satirical epic poem Don Juan; “melancholy merriment”, An oxymoron is a rhetorical and epigrammatic device for effect, often revealing paradox. The effect I aim for here is the actualization of affect; affect made relevant and useful for education as a public good. Oxymoroning as an immediate edging of knowledge into experience, hence a way to access a proto subjective level of the affective power of X. The prefix proto indicating the first, original or earliest. I ask how we can become materially identifiable subjects for one another and what would it take to move from a mechanistic approach to education to a more machinic one. It is a view of change that does not steal my powers or affective force away. Furthermore, are the abstractions one attempts to move from imitation to imagination abstract enough? I aim for expansions in our educational rationales for social and natural sustainability. It implies an educational philosophy of multiplicity ready to support and join a creative pluralism of organization and pedagogies and simultaneously counteract predetermined and controlling pluralism of organization and pedagogies. The overarching contribution of this poem is political, pragmatic and ethical and concerns the constitution of subjectivity for education in inter- and intra-generational perspectives through taking part in polysemantic ambiguity, envisioning a modest view to the child as a knowledgeable and connectable collective. Ultimately, a view of the child is our primary measurement indicator for educational quality. The competence most important to develop for educators is impression tenderness in order to meet the expressions of the child.

Luminescence measurements: reference materials for composition of sodium adenosine triphosphate aqueous solution

The authors evaluated the possibility of using the luminometry method which allows checking the level of sanitation and hygiene in industries and is one of the most effective methods of «rapid microbiology». Such key stages of development of reference material for sodium adenosine triphosphate with the certified values as analysis of similar reference materials, selection of source material of the reference material, conducting experimental studies, and establishing the metrological characteristics of reference material with traceability to state primary measurement standard were provided in the paper. Considering that the selective optical density at the characteristic wavelength is directly proportional to the concentration of the absorbing component (sodium adenosine triphosphate), the stability of R M was studied by spectrophotometry. The stability of the RM material to assess the uncertainty of the measurement results was carried out by the isochronous method. The result of the study is the possibility of ensuring the traceability of measurement results based on luminescence to primary measurement standard by sodium adenosine triphosphate concentration. In addition to the above, the authors selected the optimal value of that concentration and established metrological properties for GSO 11606-2020 R M for the composition of sodium adenosine triphosphate aqueous solution (mass concentration: from 0,09 to 0,11 g/dm3; extended uncertainty: 0,015 g/dm3). Usage of this CRM in performing tests, calibrations, and verification of measuring instruments allows providing the unbiased assessment of the measuring capabilities of luminescent measuring instruments, including in terms of determining the error of the measurements carried out.

Calibration platform controller of the laser Doppler anemometer

Primary standards for the unit of air flow velocity often use a Laser Doppler Anemometer (LDA) as the primary measurement standard. A rotating disc with a fixed diameter is used to calibrate LDA. The paper proposes calibration platform based on the precision mechanics of HDD disk. A disk rotation controller has been developed for the platform. Deviations of the disk rotation speed do not exceed 0.01% RMS in the range of angular speeds of 600-4800 rpm.

Discussion on the Classification Criteria of Measurement System Level

According to the definition of metrological traceability in ISO/IEC Guide 99:2007(VIM 3)[1], people in the metrology field can know the level of the measurement system in the metrological traceability chain by drawing the metrological traceability diagram on the measurement results. However, if someone want to further determine which level the measurement system belongs to, it should be classified as primary measurement system, secondary measurement system, or even other measurement systems. Because the definitions of terms such as primary measurement system, secondary measurement system and other measurement systems are not included in VIM 3[1], there’s no clear classification basis for the measurement system level. Therefore, this article will discuss the definitions of terms in VIM 3[1] that are more relevant to the classification of measurement system levels, then try to formulate the classification criteria, supplemented by case studies, and hope to serve as a reference for people in the metrology field when reviewing the measurement system and judging its system level.

948 Feasibility Study of a Drive-Through Influenza Vaccination Clinic for Patients-At-Risk & Their Contacts

Background There are 3-5 million cases of severe influenza-like illness globally each year, and up to 650,000 related deaths. This high prevalence rate proves to be a heavy burden on the healthcare system with >3,000 hospitalisations and >150 ICU admissions annually. Immunisation is gold-standard for the prevention of influenza outbreaks. The HSE Influenza Immunisation Strategy allocates vaccines to be administered in primary care to patients at-risk and their contacts. However, due to the COVID-19 pandemic, this has become a logistical challenge. We aimed to design and test a drive-through influenza vaccine clinic at a large GP practice in Cork. Method We designed and implemented an online booking system for at-risk patients and their contacts. 1-minute drive-through time slots were available to book for up to 6 people per vehicle. The primary measurement was the number of patients vaccinated with a secondary measurement of time spent vaccinating these patients. Results The pilot clinic occurred on 10/10/2020 with over 600 patients-at-risk & their contacts receiving the influenza vaccination over a time period of 10 hours. The capacity of this clinic was limited by the supply of vaccines. We estimate that 1,800 people could be vaccinated over the same time period with adequate vaccine supply. Conclusions A drive-through influenza vaccination clinic can be efficiently run using an online booking system and serves as a safe, efficient, and convenient way for patients-at-risk & their contacts to receive vaccinations. This system can be rolled out efficiently each winter for influenza vaccination and could be expanded to deliver mass vaccination for SARS-CoV-2.

Infrasound measurement system for real-time in-situ tornado measurements

Previous work suggests that acoustic waves at frequencies below human hearing (infrasound) are produced during tornadogenesis and continue through the life of a tornado, which have potential to locate and profile tornadic events and provide a range improvement relative to current radar capabilities, which are the current primary measurement tool. Confirming and identifying the fluid mechanism responsible for infrasonic production has been impeded by limited availability and quality (propagation-related uncertainty) of tornadic infrasound data. This paper describes an effort to increase the number of measurements and reduce the uncertainty in subsequent analysis by equipping storm chasers and first responders in regular proximity to tornadoes with mobile infrasound measurement capabilities. The study focus is the design, calibration, deployment, and analysis of data collected by a Ground-based Local INfrasound Data Acquisition (GLINDA) system that collects and relays data from an infrasound microphone, GPS receiver, and an IMU. GLINDA has been deployed with storm chasers beginning in May 2020 and has provided continuing real-time automated monitoring of spectrum and peak detection. In analysis of sampled severe weather phenomena, the signal measured from an EFU tornado (Lakin, KS) show an elevated broadband signal between 10 and 15 Hz. A significant hail event produced no significant increase infrasound signal despite rotation in the storm. The consistency of these observations with existing fixed array measurements and real-time tools to reduce measurement uncertainty demonstrates the value of acquiring tornado infrasound observations from mobile on-location systems and introduces a capability for real-time processing and display of mobile infrasonic measurements.

Measurement Standards of Ukraine for Gas Volume Flow Rate at Pressures of 1 MPa to 5 MPa

The characteristics of the primary measurement standards of the volume gas flow rate at high pressure developed in various countries are considered. A hierarchical scheme for gas flow measuring instruments and a corresponding metrological traceability chain are presented. Described is a PVTt method, on which the primary standards of gas flow rate used in the USA, France, Japan, and Taiwan are based. The need to create in Ukraine primary measurement standards of gas flow rate at high pressure covering different parts of the total flow rate interval from 0,3 m3/h to 1800 m3/h at a pressure of 1 MPa to 5 MPa is substantiated. Metrological traceability of gas flow measurements is realized through a sequence of critical flow Venturi nozzles, which play a role of the reference flow rate material measures. The standards might be used to calibrate the primary reference Venturi nozzles of the most common 0,1 mm to 8 mm diameters. The characteristics and parameters of the standards are determined. By their metrological and technical characteristics, the standards will correspond to the state-of-the-art level. According to the programme of developing the measurement-standard facilities in Ukraine, in 2019 the primary standard PVTt-65 was created and work had started on the development of the primary standard PVTt-1800 and the working standard PE-5400. A detailed study of the metrological characteristics of the measurement standards will be the topic of further work.

Otosurgery with the High-Definition Three-Dimensional (3D) Exoscope: Advantages and Disadvantages

Background: The aim of the study was to describe our initial experience with the high-definition three-dimensional (3D) exoscope for middle ear surgery versus the operating microscope. Methods: The study included 60 randomly chosen patients diagnosed with otosclerosis (n = 30) or chronic otitis media (n = 30) with a clinical indication for surgery. The primary measurement was the subjective estimation of quality of the visibility of the operating field provided by the 3D exoscope—VITOM-3D (Karl Storz, Tuttlingen, Germany) in comparison to the operating microscope. Results: All procedures, except for two (3.3%) converted to the microscope, were successfully completed using a 3D exoscope. In both stapedotomy and tympanoplasty, the exoscope was superior to the microscope during more superficial portions of the procedures. By contrast, in deeper areas of the middle ear, the exoscope provided significantly worse visibility, but usually not suboptimal. Both intraoperative bleeding and the narrow surgical field substantially reduced the visibility with the 3D exoscope in comparison to the microscope. Conclusions: Overall, our study shows that the 3D exoscope offers excellent, highly magnified, and well-illuminated high-definition images of the surgical field. However, our experience revealed several important limitations of this system, including decreased depth perception in deep areas of the tympanic cavity and reduced visibility in a difficult surgical field, with subsequent need to switch to an operating microscope in select cases.
