Authors: Domingos Elvira , Combe Merce Manuel Nambale , Gomundanhe Almeida Meque
Published: June 2023

Um das importantes fontes de conteúdos de Química ensinados nas escolas secundárias é o livro didático de Química. Por isso, o objetivo principal do presente estudo consiste em analisar o nível do uso de livro didático de Química da 9ª classe, pelos alunos. Esse objetivo é desdobrado em seguintes específicos: (a) identificar os alunos que possuem o livro didático de Química; (b) aferir os fatores que condicionam a utilização do livro didático de Química pelos alunos; (c) identificar a fonte alternativa de informações adotada pelos alunos. Para a consecução desses objetivos, optou-se pela pesquisa qualitativa e bibliográfica. O processo de recolha de dados foi conduzido por meio de um questionário e entrevista estruturada. A primeira técnica foi aplicada a 100 alunos e já a segunda foi aplicada a quatro professores de uma das escolas secundárias da cidade de Lichinga, Niassa-Moçambique. A discussão dos resultados foi feita por meio da técnica de análise de conteúdo.  Os resultados obtidos revelam que muitos alunos não têm o livro didático de Química devido a questões económicas. Isso pode comprometer o processo da aprendizagem doa alunos.  Outros resultados evidenciam que os alunos recorrem a outras fontes de informações para resolver as atividades e exercícios propostos pelo professor.
A colonização do saber: reflexões sobre a educação no Brasil colonial
Authors: Paula Elenice de
Published: June 2023

Este ensaio tem como objetivo levantar algumas reflexões acerca da história da educação brasileira, em especial sobre as primeiras concepções de ensino desenvolvidas no país. A partir da concepção de que o ensino escolar brasileiro, desde o período colonial, foi desenvolvido como forma de auxiliar e reforçar o projeto colonizador europeu, destaco breves considerações de como, por meio do ensino escolar, foi sendo constituída uma configuração social excludente. Percebo que, o modelo eurocêntrico colonialista agiu de forma ativa na colonização do saber e pensamento. Assim, não só sob o domínio territorial, o ensino escolar desenvolvido no país auxiliou na incorporação de normas e valores sociais impostos pelos europeus. Análise essa que auxilia para compreender as continuidades e rupturas no ensino escolar do tempo presente, bem como servem para refletir a respeito do papel da educação e as expectativas construídas sobre ela no nosso tempo.

Authors: Wang Rui , Deng Jinshuo , Wu Ping , Ma Qianli , Dong Xiangting , Yu Wensheng , Liu Guixia , 王 进贤 , Liu Lei
Published: June 2023

Solar steam generation is a promising water purification technology due
to its low-cost and environmentally friendly applications in water
purification and desalination. However, hydrophilic or hydrophobic
materials alone are insufficient in achieving necessary characteristics
for constructing high-quality solar steam generators with good
comprehensive properties. Herein, novel hydrophile/hydrophobe
amphipathic Janus nanofibers aerogel is designed and used as a host
material for preparing solar steam generators. The product consists of
an internal cubic aerogel and an external layer of photothermal
materials. The internal aerogel is composed of electrospun amphipathic
Janus nanofibers. Owing to the unique composition and structure, the
prepared solar steam generator integrates the features of high water
evaporation rate (2.944 kg·m-2·h-1 under 1 kW m-2 irradiation),
self-floating, salt-resisting, and fast performance recovery after
flipping. Moreover, the product also exhibits excellent properties on
desalination and removal of organic pollutants. Compared with
traditional hydrophilic aerogel host material, the amphipathic Janus
nanofibers aerogel brings much higher water evaporation rate and salt
resistance.
Dialyl-sulfide with chalcone prevent breast cancer promoting SULT1E1 malregulations and oxidant-stress dependant HIF1a-MMPs induction.
Authors: Nazmeen Aarifa , Maiti Sayantani , Maiti Smarajit
Published: June 2023

Background: In some breast cancers, decreased estrogen-sulfotransferase
(SULT1E1) and its inactivation caused by oxidative-stress lead to
elevated E2 levels as well as hypoxia-inducible tissue-damaging factors.
Methods: Here, matrix-metalloproteases (MMP2/9) activity and
SULT1E1-HIF1α protein/gene expression (Western-blot/RTPCR) were assessed
in human breast-cancers versus their adjacent-tissues. Oxidant-stress
neutralizer, chalcone (α,β unsaturated ketone) and SULT1E1-inducer
dialyl-sulfide (source garlic; Allium sativum) were tested to prevent
cancer causing factors in rat, in-vitro and in-vivo model. The
antioxidant-enzymres SOD1, catalase, GPx and LDH, and
matrix-degenerating MMP2/9 activities were assessed (gel-zymogram).
Histoarchitecture (HE-staining) and tissue SULT1E1-localization
(immuno-histochemistry) were screened. Extensive statistical-analysis
were performed. Results: Human cancer-tissue expresses higher SULT1E1,
paralleling HIF1α protein/mRNA owing to lower LDH activity. In addition,
increase of MMP2/9 activities commenced tissue damage. However, chalcone
and DAS significantly induced SULT1E1 gene/protein, and suppressed HIF1α
expression, and MMP2/9 activities in rat tissues. Correlation of
individual parameter statistics and group statistics of t-test suggest
significant correlation of oxidative-stress (MDA) with SULT1E1
(p=0.006), HIF1α (p=0.006) protein-expression. The NPSH showed a
negative correlation (p=0.001) with HIF1α, These two proteins and
SULT1E1 mRNA expressions in human breast tumor were significantly higher
(p<0.05) compared to the adjacent tissues. Pearson correlation
data suggest, SULT1E1 is correlated with NPSH in different exposure
groups. Conclusions: Breast cancers associate with SULT1E1, HIF1α and
MMPs deregulations. Higher SULT1E1-protein in advanced cancer, remain
inactive in oxidant oxidative environment and may be re-activated in
chalcone induced reducing-state. Moreover, DAS induced SULT1E1 mRNA
expression augments its protein increment. Synergistic drug-effects
commenced HIF1α and MMPs suppression. Further studies are necessary.

Authors: Habib Ahasan , Hossain Sagar
Published: June 2023

Electric vehicle (EV) demand is increasing due to the power of the whole
energy storage system, ease of handling, and flexibility. The battery
management system is essential for safely driving the EV, increasing the
battery life. Recently Habib et al. in “Sustainable Energy Technologies
and Assessments” & “Journal of Energy Storage” reported
EV-applicable energy storage systems and proposed a cell balancing
circuit for the battery for bulk energy storage systems to use in EV,
renewable energy (RE) storage and electric grid application. The
proposed batteries’ voltage equalization circuit achieved a 0mV voltage
gap with 96% and 94.2% efficiency for Li-ion and lead batteries,
respectively, and 84.43% efficiency for supercapacitors.
Robust fractional-order proportional-integral controller tuning for load frequency control of a microgrid system with communication delay
Authors: Ruan Shitao , Vilanova Ramon , Bevrani Hassan , Zhang Weidong
Published: June 2023

The integration of renewable energy resources and uncertainties in power
system models pose significant challenges to load frequency control
(LFC). To tackle these challenges, controller tuning with robustness
constraints provides an efficient solution. In this paper, we propose a
novel approach for controller tuning in LFC of microgrid systems with
communication delay. Our approach converts the tuning task into an
algorithm that solves two parametric equations subject to robustness
constraints, resulting in high accuracy and computational efficiency. We
use a perturbed scenario with uncertain microgrid model gains and
communication delay to illustrate the tuning efficiency. Simulation
examples, including comparisons with classical tuning methods,
demonstrate the effectiveness of our proposed method.
Stable and Robust Discrete-time Tracking Control of Unmanned Vehicles Using a Finite-Time Stable Disturbance Observer
Authors: Hamrah Reza , Sanyal Amit Kumar
Published: June 2023

This work provides an asymptotically stable and robust tracking control
scheme using a finite-time stable disturbance observer in the feedback
loop, for an unmanned vehicle modeled as a rigid body. The dynamics of
the system is discretized using a Lie group variational integrator in
the form of a “gray box” dynamics model that also accounts for unknown
additive disturbance force and torque. These disturbance terms are
estimated using the finite-time stable disturbance observer in real-time
and then compensated by the control scheme. The stability analysis for
translational and rotational motions is carried out separately. It is
shown that the discrete-time control laws achieve asymptotically stable
tracking of the reference position and attitude trajectories.
Reliable NGS genotyping of MHC class I and II genes requires template-specific optimization of pipeline settings
Authors: Efstratiou Artemis , Gaigher Arnaud , Künzel Sven , Teles Ana , Lenz Tobias
Published: June 2023

Using high-throughput sequencing for precise genotyping of multi-locus
gene families, such as the Major Histocompatibility Complex (MHC),
remains challenging, due to the complexity of the data and difficulties
in distinguishing genuine from erroneous variants. Several dedicated
genotyping pipelines for data from high-throughput sequencing, such as
next-generation sequencing (NGS), have been developed to tackle the
ensuing risk of artificially inflated diversity. Here, we thoroughly
assess three such multi-locus genotyping pipelines for NGS data, using
MHC class IIβ datasets of three-spined stickleback gDNA, cDNA, and
“artificial” plasmid samples with known allelic diversity. We show
that genotyping of gDNA and plasmid samples at optimal pipeline
parameters was highly accurate and reproducible across methods. However,
for cDNA data, the same configuration yielded decreased overall
genotyping precision and consistency between pipelines. Further
adjustments of key clustering parameters were required tο account for
higher error rates and larger variation in sequencing depth per allele,
highlighting the importance of template-specific pipeline optimization
for reliable genotyping of multi-locus gene families. Through accurate
paired gDNA-cDNA genotyping and MHC-II haplotype inference, we show that
MHC-II allele-specific expression levels correlate negatively with
allele number across haplotypes. Lastly, sibship-assisted cDNA
genotyping of MHC-I revealed novel variants and haplotype-based allelic
segregation with a higher-than-previously-reported individual allelic
diversity for MHC-I in sticklebacks. In conclusion, we here provide
novel genotyping protocols for MHC-I and -II genes of the three-spined
stickleback, but also evaluate the performance of popular NGS-genotyping
pipelines and highlight the need for template-specific optimization for
reliable multi-locus genotyping.
Missing genotype imputation in non-model species using Self-Organizing Maps
Authors: Mora-Márquez Fernando , Nuño Juan Carlos , Soto Álvaro , Heredia Unai López de
Published: June 2023

Current methodologies of genome-wide Single Nucleotide Polymorphism
(SNP) genotyping produce large amounts of missing data that may affect
statistical inference and bias the outcome of experiments. Genotype
imputation is routinely used in well-studied species to buffer the
impact in downstream analysis and several algorithms are available to
fill in missing genotypes. The lack of reference haplotype panels
precludes the use of these methods in genomic studies on non-model
organisms. As an alternative, machine learning algorithms are employed
to explore the genotype data and to estimate the missing genotypes.
Here, we propose an imputation method based on Self-Organizing Maps
(SOM), a widely used neural networks formed by spatially distributed
neurons that cluster similar inputs into close neurons. We follow a
classical approach that explores genotype datasets to select SNP loci
for each query missing SNP genotype to build training sets, and that
initializes and trains the neural networks to finally use the
SOM-derived clustering to impute the best genotype. To automate the
imputation process, we have implemented GTIMPUTATION, an open source
application programmed in Python3 and with a user-friendly GUI to
facilitate the whole process. The method performance was validated by
comparing its accuracy, precision and sensitivity on several benchmark
genotype datasets with other available imputation algorithms. Our
approach produced highly accurate and precise genotype imputations and
outperformed other algorithms, especially for datasets from mixed
populations with unrelated individuals.
AUTOMATIC VEHICLE COUNTING FOR TRAFFIC MANAGEMENT SYSTEM USING IMAGE PROCESSING AND IoT
Authors: V Supriya G , R Sreelatha , R Sushmitha , B Chiranjeevi Nayak
Published: June 2023

Road traffic management is a critical component of intelligent
city administration. Traffic congestion may be efficiently addressed by
precisely calculating the number of vehicles likely to pass through a
busy intersection ahead of time. The system can predict vehicle counts
far before reaching the targeted traffic intersection by using image
processing and techniques. Furthermore, monitoring data may be
transferred through the internet to a remote-control hub situated
anywhere in the city. The technology integrates seamlessly with existing
traffic control systems, capturing vehicle pictures using strategically
placed cameras. These photos are then analyzed using image processing
techniques to count the cars properly. The data collected is sent to a
centralized administration system for real-time monitoring and traffic
analysis. Furthermore, the system optimizes traffic signal timings and
provides drivers with real-time information, resulting in considerable
congestion reduction, enhanced traffic flow, and important traffic
management insights.

Published: June 2023

Service-learning has spread significant­ly in higher education in recent decades. Its effects in the academic field (students and teachers) and in the community (disadvan­taged groups at risk of social exclusion and socio-educational partners) are backed by re­search. However, few works have considered the evaluation of these projects, and there are few instruments available for guiding their de­velopment and for assessing their quality. The aim of this study is to develop criteria to eval­uate university service-learning projects. To do so, we used the Delphi method with three rounds of expert consultation. The result is a university service-learning, indicator matrix with 9 dimensions and 43 indicators. We con­clude that, as well as evaluating the quality of service-learning projects, this instrument could also be valid for validating social inno­vation from the educational sphere. The prin­cipal limitations to overcome are the still-ex­isting welfare perspective and difficulties with involving the recipients of the service.

Design and numerical analysis of a composite system of a household biogas digester with pretreatment
Authors: Liu Enhai , Zhang Wenyun , Huang Qian , Wan Wenlei , Wang Shuaipeng
Published: June 2023

The rural household biogas digesters are studied in this paper, and numerical
analysis is used to simulate the effects of light climates in the cold
season and the heat of sunlight on the temperature distribution in the pool.
The numerical results show that the uneven distributions of light intensity
and temperature in the biogas digester have a great influence on its
cumulative gas production. The central area has a significant heat
collection effect, the inner wall is weaker, and the temperature near the
top is slightly higher than that in the lower area, and the vertical
temperature changes in a decreasing trend. Aiming at the different
photo-climatic conditions of the household biogas digester and the uneven
heat collection and temperature distribution in different periods, the
traditional slag pumping work is cumbersome, and the utilization rate of
the biogas residue is low, so a new household with pretreatment is proposed.
An intelligent temperature control system is designed for the biogas tank to
analyze the adverse effects of straw fermentation at low temperature,
insufficient gas production and low resource utilization.

Published: June 2023

The shear thickening fluid as a protective material has received increasing
attention, and its impact resistance and its rheological properties are
controllable by integrating various kinds of additives to a single phase
shear thickening fluid. In this paper, the rheological properties of shear
thickening fluids with 26 wt.% fume silica, PEG200 and different mass
fraction of multi-walled carbon nano-tubes are investigated, and the effect
of temperature from -5?C to 55?C on steady state rheological properties of
1.0 wt.% multi-walled carbon nanotubes reinforced shear thickening fluids is
studied. Finally a single yarn pull-out test is conducted to examine the
influence of multi-shear thickening fluid on the shear strength and
inter-yarn friction of fabrics. The results show that the addition of
multi-walled carbon nanotubes can improve significantly the viscosity and
shear thickening efficiency.

Published: June 2023

In response to the call for carbon neutrality and control of CO2 emission,
this paper proposes a high temperature cascade heat pump system with double
medium and low temperature heat sources. Compared with those with a single
heat source, the new system has obvious advantages in energy saving and
carbon emission. An experiment is designed where the temperature of medium
temperature heat source keeps unchanged, revealing that, compared with a
single low temperature heat source, the heating capacity of low temperature
heat source reduces by 2.9%, the heating capacity of medium temperature
heat source increases by 31.1%, the total power consumption of the heat
pump increases by 3%, and the heating capacity of the heat pump increases by
4.3%.
Business Strategy and Cybersecurity Breaches
Authors: Li Tianpei , Walton Stephanie
Published: June 2023

This study examines whether a firm’s business strategy is an underlying determinant of cybersecurity breach likelihood. Based on organizational theory, firm strategy can focus on innovation or efficiency, with innovative strategy firms being more likely to have weaker, decentralized control systems, multiple technologies, and greater risk than firms with an efficiency-focused strategy. Following the Miles and Snow (1978) strategy topology, we predict and find that the prospector business strategy is associated with greater breach likelihood. We further explore IT awareness within the firm. Ex ante, it is unclear whether strategic IT policy formation is impounded into a firm’s strategy or can be impacted by individual executives and nonstrategy firm characteristics. We find that IT understanding at the executive or firm level can affect the relationship between strategy and breach likelihood. Collectively, our results indicate that business strategy is a useful indicator in evaluating firms’ cybersecurity activities.

Published: June 2023

OBJECTIVE

To estimate the rates of diabetes complications and revascularization procedures among people with diabetes who have experienced homelessness compared with a matched cohort of nonhomeless control subjects.

RESEARCH DESIGN AND METHODS

A propensity-matched cohort study was conducted using administrative health data from Ontario, Canada. Inclusion criteria included a diagnosis of diabetes and at least one hospital encounter between April 2006 and March 2019. Homeless status was identified using a validated administrative data algorithm. Eligible people with a history of homelessness were matched to nonhomeless control subjects with similar sociodemographic and clinical characteristics. Rate ratios (RRs) for macrovascular complications, revascularization procedures, acute glycemic emergencies, skin/soft tissue infections, and amputation were calculated using generalized linear models with negative binomial distribution and robust SEs.

RESULTS

Of 1,076,437 people who were eligible for inclusion in the study, 6,944 were identified as homeless. A suitable nonhomeless match was found for 5,219 individuals. The rate of macrovascular complications was higher for people with a history of homelessness compared with nonhomeless control subjects (RR 1.85, 95% CI 1.64–2.07), as were rates of hospitalization for glycemia (RR 5.64, 95% CI 4.07–7.81) and skin/soft tissue infections (RR 3.78, 95% CI 3.31–4.32). By contrast, the rates of coronary revascularization procedures were lower for people with a history of homelessness (RR 0.76, 95% CI 0.62–0.94).

CONCLUSIONS

These findings contribute to our understanding of the impact of homelessness on long-term diabetes outcomes. The higher rates of complications among people with a history of homelessness present an opportunity for tailored interventions to mitigate these disparities.
A Scoping Review of the Relation Between Toothbrushing and Diabetes Knowledge, Glycemic Control, and Oral Health Outcomes in People With Type 2 Diabetes
Authors: Lipman Ruth D. , O’Brien Kelly K. , Bardsley Joan K. , Magee Michelle F.
Published: June 2023

Objective

Given the bidirectional relationship between type 2 diabetes and periodontal disease, this study sought to compile the available data regarding the relationship between home oral hygiene, specifically toothbrushing, and glycemic control and oral health in people with type 2 diabetes.

Methods

A systematic scoping review was conducted using a combination of controlled vocabulary and keyword terms for type 2 diabetes and home oral care in PubMed and CINHAL. Publications from the past 20 years were considered for inclusion. Study data were summarized.

Results

A total of 11 studies met our inclusion criteria. In all survey research identified, self-report of more frequent toothbrushing in people with type 2 diabetes was always found to be associated with self-report of better glycemic control and was often associated with better clinician-conducted measures oral health. In the interventional studies identified, health coaching about oral health was associated with improvements in glycemic control, and health coaching compared with health education was found to be associated with enhanced improvement in glycemic control and self-reported toothbrushing behavior.

Conclusion

The available data suggest that improved engagement in toothbrushing behavior may be associated with improved oral health and better glycemic control in people with type 2 diabetes. Whether improvement in glycemic control is a direct result of change to the oral environment, succeeding with one behavior change stimulating engagement in other health behavior changes, a combination of the two, or something else cannot be determined from this review. Additional studies are needed to further explore the potential for oral health coaching to improve the well-being of people with type 2 diabetes.

Objective: To compare the incidence of type 1 diabetes (T1D) before and during the COVID-19 pandemic and if SARS-CoV-2 is associated with T1D development.

Research Design and Methods: All Danish residents under 30 years free of diabetes from 2015 to 2021 were included. Individuals were followed from 01.01.2015 or birth until the development of T1D, the age of 30, the end of the study (31.12.21), emigration, development of type 2 diabetes, onset of any cancer, initiation of immune modulating therapy, or development of any autoimmune disease. We compared the incidence rate ratio (IRR) of T1D using Poisson regression models. We matched each case with a SARS-CoV-2 infection with three controls and used a cause-specific Cox-regression model to estimate the hazard ratio.

Results: Among 2,381,348 individuals, 3,579 cases of T1D occurred. The adjusted IRRs [95% confidence interval] for T1D in each quarter of the year in 2020 and 2021 compared to 2015-2019 were: Jan-Mar-2020: 1.03 [0.86;1.23], Jan-Mar-2021: 1.01 [0.84;1.22], Apr-Jun-2020: 0.98 [0.80;1.20], Apr-Jun-2021: 1.34 [1.12; 1.61], Jul-Sep-2020: 1.13 [0.94;1.35], Jul-Sep-2021: 1.21 [1.01;1.45], Oct-Dec-2020: 1.09 [0.91; 1.31], Oct-Dec-2021: 1.18 [0.99; 1.41]. We identified 338,670 individuals with a positive SARS-CoV-2 test and matched them with 1,004,688 controls. A SARS-2-CoV infection was not significantly associated with the risk of T1D development (Hazard rate ratio of 0.90 [0.60-1.35]).

Conclusions: There was an increase in T1D incidence during Apr-Jun 2021 compared to Apr-Jun 2015-2019, but this could not be attributed to the SARS-CoV-2 infection.

Published: June 2023

  

Suboptimal glycemic control among women with type 1 or type 2 diabetes before conception and during the early part of pregnancy is a powerful risk factor for fetal anomalies, macrosomia, and stillbirth. Major congenital anomalies occur in up to 25–30% of infants of women with type 1 or type 2 diabetes (1). Hyperglycemia during fetal organogenesis (5–8 weeks after the last menstrual period) is a considerable teratogen, and, consequentially, the risk of fetal anomalies related to preexisting maternal diabetes can be reduced to background risk when glycemic control is at goal.

Risk of Serious Infections in Patients with Bullous Pemphigoid: A Population-based Cohort Study
Authors: Chang Tsung-Hsien , Wu Chun-Ying , Chang Yun-Ting , Lyu Ying-Syuan , Wu Chen-Yi
Published: June 2023

Patients with bullous pemphigoid are susceptible to serious infections, which are the leading cause of death in these patients. The aims of this population-based cohort study were to investigate the incidence and spectrum of serious infections in patients with bullous pemphigoid and to identify associated risk factors. The outcome measure was any infection requiring hospitalization. Hazard ratios with 95% confidence intervals were estimated using subdistribution hazard models. In total, 12,300 patients with bullous pemphigoid and 49,200 matched controls were identified through the National Health Insurance Research Database in Taiwan. Within 2 years of bullous pemphigoid diagnosis, 5,006 (40.7%) patients developed serious infections, with an incidence of 385.5/1,000 person-years. Patients with bullous pemphigoid were twice as likely to develop serious infections as controls (adjusted hazard ratio, 2.01; 95% confidence interval 1.92–2.10). Systemic corticosteroid use was the strongest risk factor, resulting in a 2-fold increase in the risk for serious infections. Other independent risk factors were advanced age, female sex, low income, and certain comorbidities. In conclusion, this study demonstrated an increased risk of serious infections following a diagnosis of bullous pemphigoid. Prophylaxis of serious infections through active intervention with the risk factors may be essential in reducing the morbidity and mortality associated with bullous pemphigoid.
Feasibility of inspiratory muscle training for patients with persistent dyspnoea after COVID-19 infection: A pilot study
Authors: Collet Romain , Van Egmond Maarten , Van der Schaaf Marike , Major Mel
Published: June 2023

Objective: This study investigates the feasibility of delivering inspiratory muscle training as part of the physical therapy treatment for patients with post-COVID dyspnoea.Design: Mixed-methods pilot study.Subjects/patients: Patients with complaints of dyspnoea after COVID-19 infection and their physical therapists.Methods: The Amsterdam University of Applied Sciences and the Amsterdam University Medical Centers conducted this study. Participants performed daily inspiratory muscle training at home for 6 weeks, consisting of 30 repetitions against a pre-set resistance. The primary outcome was feasibility assessed as acceptability, safety, adherence and patient- and professional experience obtained through diaries and semi-structured interviews. The secondary outcome was maximal inspiratory pressure.Results: Sixteen patients participated. Nine patients and 2 physical therapists partook in semi-structured interviews. Two patients dropped out before initiating the training. Adherence was 73.7%, and no adverse events occurred. Protocol deviations occurred in 29.7% of the sessions. Maximal inspiratory pressure changed from 84.7% of predicted at baseline to 111.3% at follow-up. Qualitative analysis identified barriers to training: ‘Getting acquainted with the training material’ and ‘Finding the right schedule’. Facilitators were: ‘Support from physical therapists’ and ‘Experiencing improvements’.Conclusion: Delivering inspiratory muscle training to patients with post-COVID dyspnoea seems feasible. Patients valued the simplicity of the intervention and reported perceived improvements. However, the intervention should be carefully supervised, and training parameters adjusted to individual needs and capacity.
LAY ABSTRACTMany people who have recovered from a COVID-19 infection develop persistent shortness of breath, fatigue and difficulties with memories, learning new things or making decisions. This condition affects their daily life and is called post-COVID syndrome. Inspiratory muscle training is a technique that aims to help people to breathe more easily by strengthening and improving the coordination of breathing muscles. We undertook this study to determine if performing such training was possible for these patients. We interviewed 2 physiotherapists who provided the training and 9 of their patients. In addition, we looked into the diaries 16 patients kept about their training to learn about their experiences or unexpected (medical) problems they might have had with the training. We found that the training seemed reasonable since patients and their physiotherapists found it simple, and no negative experiences happened. However, patients said it helped if the physiotherapist supervised them during the training.
Unique Amphibole-Bearing Mantle Column Beneath the Leningrad Kimberlite Pipe, West Ukukit Field, NE Yakutia
Authors: IV Ashchepkov
Published: June 2023

In the subcratonic lithospheric mantle (SCLM) beneath Leningrad pipe (West Ukukit field), Yakutia garnet thermobarometry allows us to identify seven horizons (paleo subduction slab). Microprobe data for Cr-bearing amphiboles >500 grains from mantle xenoliths and concentrates reveal a broad range of compositions changing from Cr- pargasitic hornblendes to pargasites, edinites, kataforites, К-richterites with increasing pressure determined with new amphibole thermobarometer constructed by the first author The low pressure (LP) Cr-hornblendes and pargasites compiles the high-temperature branch (90-60 mw/m2) from 3.5 GPa to Moho traced by basaltic cumulates. In the middle part of SCLM edinites mark 35 to 40 mw/ m2 geotherms. At high pressures kataforites also vary in thermal conditions. Richterites near the lithosphere base trace both low –and high temperature convective branches. The amphiboles reveal divisions into 9 chemical groups. The melts coexistion with amphiboles has concave patters typical for subduction related melts. LP varieties reveal Eu inflection U, Rb, Ba, Sr peaks and deep troughs in HFSE (except Zr), Pb. The pargasites show high U peaks and relativle less HFSE depressions. Encreasing in pressure for edinites, kataforites and richterise are accompanied byrise in U and Zr peak gentling of depressions in Th, Sr, Nb and Hf and less in Nb,Ta, Hf and peak in Zr and also decrease in LREE and REE. Clinopyroxenes and garnets show variable trace element patterns and divisions in groups with the plume and subduction signatures. The contrasting behaviour of Ta and Nb is regulated by the rutile partition coefficients likely for primary eclogites. A subduction and Na and K (siliceous) type of fluids percolated through the mantle with abundant eclogites possibly was accompanied by amphibolization at the different levels through all the mantle column. The plume melts produced hybridism with the mantle metasomatic assembleges which created smoother trace element patterns in reacted minerals, clinopyroxene. The new version of monomineral amphibole thermobarometry is suggested.
Investigating the Performance of Co [AM-AMPS-MALEIC-AAC]/ PEI-MBA Nanocomposite Hydrogel in Sand Control from Oil Reservoirs
Authors: M Baghban Salehi
Published: June 2023

Sand production is one of the major challenges in oil and gas production from sandstone reservoirs. Production losses, formation damage, corrosion, and equipment failure are all consequences of sand production. Various mechanical and chemical methods are used to control sand production. One of the most efficient chemical methods is the injection of hydrogels, but its application has been constrained by the hydrogels' weak stability in the harsh conditions of the reservoir. A Co [AMAMPS-MALEIC-AAC]/PEI-MBA nanocomposite hydrogel with superior viscoelastic properties and double crosslinking was developed and synthesized to overcome these restrictions. Swelling, rheology, and morphology tests were utilized to predict the produced nanocomposite's effectiveness and performance in the harsh Iranian reservoirs. According to the obtained results, at ambient temperature (25°C, during injection) and reservoir temperature (90°C, placed in a porous medium), in distilled water, the maximum swelling ratio was 8.5 and 94, and in formation water, the maximum swelling ratio was 5.4 and 10.8, respectively. The X-ray diffraction test findings show that the nanoparticles are uniformly distributed throughout the structure. Also, according to the results of the thermal strength test, the sample’s thermal stability up to 90°C was confirmed with less than 0.6 wt% degradation. The results of the strain sweep, frequency sweep and stress-strain tests demonstrate the existence of a robust, three-dimensional, and viscoelastic structure up to a strain of 100% and a frequency of 100 Hz. In the strain sweep test with a constant frequency of 1 Hz, the maximum storage modulus was reported as 27,000 Pa, and in the frequency sweep test with a constant strain of 1%, 18,000 Pascals were reported. The stress-strain test revealed that the ultimate tensile strength of the synthesized material was 4630 pascals. These characteristics make the aforementioned nanocomposite hydrogel ideal for usage in porous media.
Review of Embedded Discrete Fracture Models: Concepts, Simulation and Pros & Cons
Authors: S Rostami
Published: June 2023

The oil and gas industry faces significant challenges when simulating fractured reservoirs. With the rising cost of hydrocarbons, there is a growing interest in exploiting unconventional reservoirs using hydraulic fracturing technologies. However, unconventional reservoirs typically contain fractured systems at various scales, ranging from nano to kilometer, making it difficult to simulate and predict these reservoirs accurately. Therefore, a rapid and precise method is crucial for this purpose. This paper presents a comprehensive review of the Embedded Discrete Fracture Model (EDFM), a novel approach designed for this purpose. This work begins by reviewing and comparing common methods for simulating naturally and hydraulically fractured reservoirs with EDFM, considering each method's advantages and disadvantages. The concept and formulation of EDFM are then discussed, focusing on adding mass balance equations and making them compatible with reservoir simulators. Additionally, this paper considers the concept and application of non-neighboring connections, which are crucial in simulating fractured reservoirs using EDFM models. This work also highlights the importance of considering changes in the EDFM formulation and simulation when fractures are treated as dynamic systems; failure to do so can lead to significant errors that deviate from actual results. Finally, the disadvantages of EDFM and proposed solutions for enhancing this method are discussed.
