A Review on the Morbidity and Mortality in COVID-19 Patients with
Pre-existing Asthma in India
Authors: Saini Prabhnoor , Mungreiphy N.K. 
Published: June 2024

Abstract:
The global epidemiology of asthma shows a complex association with COVID-19 regarding morbidity, comorbidity, and mortality. This study aimed to shed light on the relationship between
COVID-19 and pre-existing asthma, specifically within the Indian context, considering the large
population and significant burden of asthma. To review and integrate the available data on morbidity,
comorbidity, and mortality outcomes of COVID-19 patients with pre-existing asthma in India, fulltext articles were searched between December 1st, 2019 to April 20th, 2023, in Science Direct and
PubMed on studies with COVID-19 patients suffering from asthma. A total of 893 articles were
screened based on a certain inclusion criterion, and 15 full-text articles were eligible for the review.
The studies included 10,239 participants comprising 73.47% (n= 7523) of COVID-19 patients. More
males (n= 4993) were affected by COVID-19 infection compared to females (n= 2510). A total of
262 (3.48%) COVID-19 patients had pre-existing asthma, and 58 deaths (0.77%) were observed
among them. South India exhibited the highest number of COVID-19 patients with asthma comorbidity (5.38%), while North India had the lowest number of COVID-19-infected patients with preexisting asthma (1.69%). The highest mortality was found among patients with asthma across India
(7.14%), and the lowest mortality (0.12%) was reflected in cases from North India. This review
showed less asthma comorbidity and mortality cases in COVID-19 patients in India. The study indicated higher COVID-19 infection rates in males. Regional disparities were observed in COVID-19
patients with asthma comorbidity and mortality. In contrast, few studies have reported higher asthma
comorbidity and mortality in COVID-19 patients with pre-existing asthma.
Measurement of Viscoelastic Properties by Free Loading-Mass Method
Authors: V.M. Kulik 
Published: June 2024

Background:
A procedure for determining the elastic and viscous properties of the sample material on the basis of the forced vibrations of a sample of mass m loaded with a certain mass M is developed. One of advantages of using the top mass instead of a rigid fixation is the appearance of an additional deformation resonance, the frequency of which is < √ M / m times smaller than the resonance frequency of the fixed sample.

Method:
The experimental setup implementing the free mass method is described. Notably, the
proposed scheme does not require any adjustment and is assembled from standard devices. By
changing the design of the sample only, both shear and compression-tension strains can be measured.
The combination of these methods allows measuring the complex Poisson’s ratio, in addition
to modulus of elasticity and loss factor.

Results:
One-dimensional (1D) and two-dimensional (2D) models of specimen deformation are
considered. For the 1D deformation model, approximate formulas for calculating the modulus of
elasticity and the loss factor are substantiated and the limits of validity these formulas are outlined.
Improving the accuracy of measurements is also considered. To do this, it is necessary to
fully describe the boundary conditions on the deformable sample. The developed 2D model of
sample deformation made it possible to calculate the elastic modulus form factors for various
samples with axial symmetry.

Conclusion:
The method may become a Standard for measuring viscoelastic properties of materials
(complex elastic and shear modulus, as well as complex Poisson's ratio).
Efficiency and performance of autothermal reforming systems for the production of hydrogen in continuous flow reactors
Authors: Chen Junjie 
Published: June 2024

Computational modelling for microchannel reactor design was conducted in
the attempt to fully understand autothermal reforming phenomena in a
continuous flow reactor. The effects of pressure and flow rate on the
efficiency and performance of the reactor were evaluated by performing
computational fluid dynamics under different design conditions. The
reactor efficiency and performance were assessed by means of the
reactant conversion, product yield, reaction rate, hydrogen
productivity, and output power. Recommendations for designing an
autothermal reforming system were made and strategies for performing
efficient operation were set forth. The results indicated that the
pressure and flow rate set strict limits on operation, and there is a
trade-off between high productivity and low conversion. The pressure and
flow rate play competing roles in the reactor efficiency and
performance. Lower pressures and flow rates can increase the conversion
and yield, but higher pressures and flow rates can significantly improve
the hydrogen productivity and output power, which is essential to the
success of start-up and acceleration of the downstream equipment. There
may exist an optimum pressure and flow rate in terms of both efficiency
and performance. The calculated output power is of the order of
thousands of kilowatts per cubic meter.

Air temperature trends and extreme warming events across regions of Antarctica for the period 2003-2021
Authors: Nielsen Eva Bendix , Katurji Marwan , Zawar-Reza Peyman , Cullen Nicolas J. 
Published: June 2024

We have characterized the magnitude and spatial extent of observed
regional and inter-regional air temperature trends and warming extremes
across Antarctica. Prior studies have used localized observational
records to analyze air temperature trends across distinct geographical
regions, leaving local and inter-regional variations to be undetected.
Using the high-resolution temperature product AntAir ICE, air
temperature trends and extreme warming events during austral summers
were identified across Antarctica for the period 2003-2021. Unsupervised
clustering was applied to austral summer and annual mean air temperature
trends to divide Antarctica into 12 regions exhibiting similarity in
temperature trends. Our results show a significant annual mean cooling
trend of - 0.12 °C/Yr for the terrestrial Antarctic Peninsula, and an
austral summer (annual) warming trend of + 0.08°C/Yr (+0.07 °C/Yr) in
the Ross Sea region’s Victoria Land and Transantarctic Mountains. The
spatial extent of each of the 12 clusters’ extreme air temperature
events was mapped revealing that West Antarctica has spatially confined
events, while East Antarctica events are widespread. ERA5 data indicates
that West Antarctica’s extreme air temperature events are associated
with consistent meridional atmospheric flows. Local to regional extreme
warming events in East Antarctica are associated with inland
high-pressure systems, which enhance katabatic winds. Localized warming
events around complex coastal geographies were detected and appear to be
related to mesoscale wind systems such as foehn but require further
investigation using mesoscale numerical weather models. This work
highlights the necessity for ongoing and new monitoring in regions where
critical ecological and physical thresholds are being surpassed.
358-OR: Remote CGM Monitoring in People with Type 2 Diabetes (T2D) in an Under-resourced Setting
Authors: RUELAS VALERIE F. , PETERS ANNE L. 
Published: June 2024

Objective: To implement CGM and remotely monitor patients with T2D treated in a safety net clinic to allow for patient outreach between routinely scheduled visits and provide feedback to health care providers (HCP’s) for algorithm-based medication management.
Methods: Patients were provided a Libre 2 CGM and followed via LibreView. Baseline clinical data and AGP’s were evaluated by the PI and management recommendations were sent to the patient’s HCP. Project staff reviewed the LibreView portal daily and contacted subjects who had glucose values either above 250 mg/dl or below 70 mg/dl more than 5% of the time and provide diabetes education. Clinical data updates and AGPs were sent to the PI based on need (from weekly to monthly) so additional diabetes management recommendations could be provided. Measures administered at baseline, 6 months and 12 months were assessed for Shapiro-Wilk normality and paired dependent t-tests. A 2-sided alpha of 0.05 was used.
Results: Interim results of 137 of 200 enrolled subjects (52 not on insulin and 85 on insulin) showed improvements in the following measures from baseline to 6 months: Mean baseline A1C = 9.0% decreased to 7.8% by 6 months (-1.2 +/- 1.7 (SD), p&lt;.001). TIR mean increase was 12.5 +/- 27.7 (SD), p&lt;.001. GMI was reduced by -.591 +/- .59, p&lt;.001. A slight reduction in depression was seen -0.847 +/- 4.6 (PHQ8, p= .036). Diabetes Distress Scale (DDS) showed reduced stress for non-insulin users -1.23 +/- 3.5, p= .012 and for insulin users -2.8 +/- 4.6, p = .005. HCPs implemented recommendations 75% of the time and use of GLP-1 RA’s doubled, based on recommendations sent to HCP’s. Analysis of 91 subjects who completed 12 months show sustained outcomes.
Conclusions: Remote monitoring coupled with education and medication recommendations provided to HCPs improved diabetes outcomes in people with T2D, on insulin and non-insulin therapies.

Polymer scaffolds were made by electrospinning from a 12% solution of poly(ε-caprolactone) or a 12% solution of polyurethane. Surface structure was examined by scanning electron microscopy, whilst cytotoxicity was evaluated by seeding EA.hy 926 endothelial cells on scaffold surface for 72 hours. Cell culture viability and proliferation was assessed by MTT assay and by quantifying cell culture density. On the xCELLigence device, cells were cultured in the presence of the studied matrix samples, and the dynamics of cell culture growth was evaluated in real time.Results. Poly(ε-caprolactone) scaffolds were characterised by a higher variability in the filament thickness and by a significantly larger pore size. Polyurethane filaments formed a dense web with a smoother surface. Poly(ε-caprolactone) scaffolds had significantly higher biocompatibility in comparison with polyurethane. Adhesion of cells to poly(ε-caprolactone) scaffolds did not differ from the cell culture plastic, and poly(ε-caprolactone) supported cell proliferation in the MTT test. Poly(ε-caprolactone) and polyurethane did not differ significantly in terms of inducing cell proliferation. Both poly(ε-caprolactone) and polyurethane scaffolds did not pose considerable cytotoxicity.Conclusion. Poly(ε-caprolactone) and polyurethane scaffolds did not exhibit cytotoxic effects and can be used for manufacturing polymer scaffolds of vascular grafts.

Abstrak: Komputer semakin dikenal oleh masyarakat sebagai akibat dari perkembangan teknologi informasi yang sangat cepat. Komputer sekarang digunakan bukan hanya sebagai alat untuk mengolah data tetapi juga sebagai alat yang membantu orang melakukan berbagai tugas, baik di kantor maupun di rumah. Komputer juga sudah mulai digunakan di sekolah, membantu siswa belajar. Pendidikan harus melakukan inovasi untuk mendorong pertumbuhan bahasa asing. Salah satunya adalah menggunakan media sebagai alat pembelajaran bahasa asing. Ini disebabkan oleh fakta bahwa metode pembelajaran konvensional, di mana guru menjelaskan dan siswa hanya duduk dan mendengarkan, dianggap kurang efektif dalam memberikan pembelajaran. Dalam pengembangan media pembelajaran bahasa prancis ini, pendekatan komputer terbantu pembelajaran digunakan. CAI adalah program pembelajaran dengan memanfaatkan komputer dengan struktur program yang terdiri dari desain bentuk (aplikasi perangkat lunak), isi (pesan pembelajaran), dan pendukung (perangkat lunak yang diperlukan untuk menjalankan program, teks, audio, video, grafis, dan sebagainya). Hasil penelitian ini menunjukkan bahwa membuat media pembelajaran berbasis multimedia untuk bahasa Prancis memiliki prospek yang baik. Kata Kunci: Media Pembelajaran, Bahasa Prancis, Multimedia, CAI. Abstract: Computers are increasingly known by the public as a result of the rapid development of information technology. Computers are now used not only as a tool to process data but also as a tool that helps people perform various tasks, both in the office and at home. Computers have also begun to be used in schools, helping students learn. Education must innovate to encourage the growth of foreign languages. One of them is using media as a foreign language learning tool. This is due to the fact that conventional learning methods, where teachers explain and students just sit and listen, are considered less effective in delivering learning. In the development of this French language learning media, a computer-aided learning approach is used. CAI is a learning program by utilizing a computer with a program structure consisting of form design (software application), content (learning message), and supporting (software needed to run the program, text, audio, video, graphics, and so on). The results of this study show that making multimedia-based learning media for French has good prospects. Keywords: Learning Media, French, Multimedia, CAI.
