Published: September 2023

Researchers focuses on their study on sustainable and environmentally friendly building materials like Geopolymer concrete (GPC). There were several studies done in the literature to find the performance of GPC structural members under different loading conditions and checked their performance against Ordinary Portland cement (OPC) concrete. Slabs are the most important structural members and it is very significant to find the behaviour under impact loads and it is not always adequately understood. The purpose of this study is to examine how an alkali-activated slag slab behaves under impact loading and utilizing the ANSYS software, a 3D nonlinear finite element analysis was performed. To validate the numerical model that was utilised, the slab models were first calibrated using existing experimental data and then parametric tests were conducted utilising various reinforcement ratios and their spacings. The results showed that GPC slabs showed better performance and the deformation decreased with increase in reinforcement ratios.

Authors: A. Alfiya , R. Pranavya J. , S Indu M , J. Sajithkumar K.
Published: September 2023

Photocatalysis is an environmentally friendly technique for removing organic pollutants such as dyes, pesticides, etc. The photo reactors could be of the slurry type and fixed bed type. Continuous flow photocatalytic reactors generally are fixed bed-type reactors. Slurry type designs like loop thin-film slurry flat-plate photoreactors, step aeration slurry reactors etc. were also tried out for continuous flow operations. Continuous flow photocatalytic reactors have become one of the most ensuring methods for the treatment of mass water. However, uniform dispersion of the photocatalyst within the wastewater volume is still existing as a challenge. Different reactor designs like immobilized bed reactors (packed bed reactor and fluidized bed reactor), annular reactor with photocatalyst coated on inner/outer cylinder, photocatalytic membrane reactors, tubular reactors, microreactors, etc. are tested for their efficiency. This review tries to provide a generalized comparison of the relative merits and demerits of these reactor designs and immobilization methods on the degradation of organic contaminants.

Authors: M. Mervin Raj , C. Munavar Fairooz
Published: September 2023

The transportation facilities are used for the efficient transfer of goods and services. Even though the safety is the major concern for a transportation engineer. Among the road users, the pedestrians are the ones more vulnerable to conflicts. When conflicts occur, pedestrians came to direct impact without any protection rather than other road users such as vehicle users and passengers having some means of protection. Many studies have been done related to safety of pedestrians near intersections where the violation behaviour is more. But there is lack of study in midblock locations which was identified as the gap for study. The study mainly aimed to analyse the perception of pedestrians towards bus stop, crosswalk and sidewalk and to find out the violation behaviours while using these facilities and model creation to find out the safety of pedestrians in Kollam district at 3 selected bus stops. The data collected through questionnaire and video were used for analysis of perception of pedestrians towards each facility, violation behaviour and model creation. The modelling was done with help of IBM SPSS Statistics. The results indicated that the charging facility is one of the requirements in all the selected bus stops and the violation behaviour due to various factors were also identified. A model was also developed to predict the post encroachment time based on walking speed and waiting time of pedestrians and vehicle speed. Based on the predicted value, if it is lower than critical PET value then the bus stop location can be considered as unsafe, which requires additional safety improvements. The model given 57% predictive accuracy based on the selected attribute walking speed, waiting time and vehicle speed depending on each pedestrian behaviour, which is indicated by the R2 value from multilinear regression analysis. So, there are other factors in which the post encroachment time depends which indicates the safety level of pedestrians.

Authors: Shu Hongfei , Zhao Peng , Zhu Rui-Dong , Zou Hao
Published: September 2023

We count the physical Bethe states of quantum integrable models with twisted boundary conditions using the Witten index of 2d supersymmetric gauge theories. For multi-component models solvable by the nested Bethe ansatz, the result is a novel restricted occupancy problem. For the SU(3) spin chain and the t-J model, we propose formulae for the solution count on singular loci in the space of twist parameters.

Non-alcoholic Fatty Liver Disease
Authors: Banerjee Goutam , Papri Suraya R. , Satapathy Sanjaya K. , Banerjee Pratik
Published: September 2023

Nonalcoholic fatty liver disease (NAFLD) is a spectrum of liver conditions, and its
growing prevalence is a serious concern worldwide, especially in Western countries. Researchers
have pointed out several genetic mutations associated with NAFLD; however, the imbalance of
the gut microbial community also plays a critical role in the progression of NAFLD. Due to the
lack of approved medicine, probiotics gain special attention in controlling metabolic disorders like
NAFLD. Among these probiotics, Akkermansia muciniphila (a member of natural gut microflora)
is considered one of the most efficient and important in maintaining gut health, energy homeostasis, and lipid metabolism. In this perspective, we discussed the probable molecular mechanism of
A. muciniphila in controlling the progression of NAFLD and restoring liver health. The therapeutic
potential of A. muciniphila in NAFLD has been tested primarily on animal models, and thus, more
randomized human trials should be conducted to prove its efficacy.

A Personalized Recommendation System for Academic Events
Authors: Shien Chen Henry Khoo , Rathina Velu Shubashini
Published: September 2023

Academic events are growing in numbers worldwide annually for
researchers to discuss their work. The research on recommendation systems in
academic domains has high significance for researchers. The classical approach to the
recommender system uses content-based and collaborative filtering that tends to
produce poor results. The focus of the study is to determine the factors involving the
selection of academic events and create a user-based personalised recommender system
for academic events. A survey will be conducted to identify the factors affecting the
choice of events. The system will filter the results of the events using a matching
matrix by conducting a factor analysis and receiving input to find the most relevant
academic events from the database. The study's approach evaluates the result based on
the pre-processed data and the similarity measures between a similar user (Top-n) and
an active user for events with a higher probability of participation. The weighted
average of the neighbour’s ratings will be generated for the predictions of the events.
The study’s outcome will prove that the personalised recommendation system is better
than the classical approach in finding the most relevant events. The recommendation
system can be optimised in domains.
e-Health Web Application with Electronic Medical Records (EMR) and Virtual Appointments
Authors: Barakath Rahman Faridzuan Bin , Khaleel Shaikh Tanveer , Binti Mohd Saad Nurul Husna
Published: September 2023

Relying on papers to document medical records hinders the United Nations’
goal of creating a more sustainable world for future generations. With the excess usage
of paper, the world is contributing towards global warming. Medical staff tends to take
a long time to pull out a patient’s medical record when it can be done in a matter of
seconds. Being paperless does not immediately mean it is effective or transparent, as
medical providers don’t usually share the content of a patient’s medical record with the
patient itself, let alone a different medical provider. Another issue is the lack of
transparency within the healthcare sector. This research focuses on the need for
Malaysia to have an e-Health system, preparation and participation towards the e-Health system, and the security of migrating towards the e-Health system.

Published: September 2023

Since the conception of biosensor technology in biomedical research, this
field is emerging as a promising and high-throughput tool for neuro-engineering and
neurosciences research. It has been postulated that the accumulating property proteins
are the basic cause of neurodegenerative diseases, such as Parkinson’s disease,
Alzheimer’s disease and prion diseases. Thus, neurodegenerative diseases are also
called “protein misfolding disorders”. Biosensors have a wide range of applications in
biomedical research, including optical and electrochemical detection of biometal.protein interactions, detection of biomarkers, such as β-amyloids, apolipoprotein, and
tau proteins, and microRNA in blood and cerebrospinal fluid in neurodegenerative
diseases. These are composed of primary biological recognition elements that convert
the chemical signal into the voltage or current that evaluates the physical signal by
preparing a plot of sensor response against the analyte concentration. This chapter
presents a bird’s eye view on various aspects of progress in biosensor development
with special emphasis on their application, including metal-protein interactions studies,
detection of neurotransmitters using aptamers and calixarenes, detection of biomarkers
proteins, such as α-synuclein for Parkinson’s disease, apolipoprotein, tau and β-amyloid proteins for Alzheimer’s disease, and prion proteins. The chapter also
summarizes the novel materials reported for improved biosensor performance. This
chapter will be of high relevance to the biological scientists working in neuro-engineering and neurosciences research

In the Sibundong watershed encountered incomplete discharge measurement problems, many empty discharge observations, and prolonged discharge data. With the tank model, it is expected to be able to perform a discharge simulation to find out the amount of discharge in the river. The purposes of this study are to apply the tank model in the estimation of river discharge and calculate the dependable discharge on the Sibundong river, in addition, it is also to analyze the potential power of Sibundong hydropower. From the result of the generator discharge analysis, it can be analyzed the probability of discharge reliability based on Flow Duration Curve that is Q = 9.29 m3/s, P = 60 %. The selected Francis turbine has a sensitivity of operating variation from 35 % to 105 % of the discharge design of the generator, the turbine operating discharge pattern is between 60 % and 100 % with consideration of dependable discharge. The power potential that can be generated for the hydro power operation pattern is 2 x 6.26 MW and the energy is 1,489.96 GWh/year.

This study aims to explain how far the effectiveness of participatory election-based supervision took place in the election of Governors and Deputy Governors of the 2017 Bangka Belitung Islands Province. The debate is becoming more and more complexes and more complexes when the idealism of the existing surveillance system collides with the real context of the field of reality. The problem will become so complicated when the theoretical conceptual building fails to explain and even becomes a guide in engineering its ideal political reality. To conduct these study qualitative descriptive research methods will be used. Primary data sources will be obtained through non-participant observation and in-depth interviews whose information is determined by purposive sampling. To help analyze this study, the theory of participatory supervision will be used which includes electoral reform and local democracy, contextualization of participatory engagement. Data analysis techniques are carried out with the stages of collecting, reducing, displaying and drawing conclusions.
Bringing the Inside Out and the Outside in: The Therapeutic Relationship in Compassion Focused Therapy Chairwork
Authors: Bell Tobyn , Montague Jane , Elander James , Pugh Matthew , Gilbert Paul
Published: September 2023

Chairwork is a central component in Compassion Focused Therapy (CFT). Despite its importance, there has been no prior research on the relational factors underpinning the application of chairwork in CFT. There is also a general paucity of research on the role of the therapeutic relationship in chairwork across modalities. This paper analyses data from interviews with 21 clients following a CFT chairwork intervention to ascertain how relational factors influenced their experience of this method. An Interpretative Phenomenological Analysis (IPA) found three main themes: 1) direction and coaching during enactment; 2) externalisation: bringing the inside out and outside in; 3) regulation and trust: the relational requirements to ‘let go’. The implications of these findings, both for the delivery and training of chairwork, are then discussed in the context of CFT.

Background

Rapid digitalization in health care has led to the adoption of digital technologies; however, limited trust in internet-based health decisions and the need for technical personnel hinder the use of smartphones and machine learning applications. To address this, automated machine learning (AutoML) is a promising tool that can empower health care professionals to enhance the effectiveness of mobile health apps.

Objective

We used AutoML to analyze data from clinical studies involving patients with chronic hand and/or foot eczema or psoriasis vulgaris who used a smartphone monitoring app. The analysis focused on itching, pain, Dermatology Life Quality Index (DLQI) development, and app use.

Methods

After extensive data set preparation, which consisted of combining 3 primary data sets by extracting common features and by computing new features, a new pseudonymized secondary data set with a total of 368 patients was created. Next, multiple machine learning classification models were built during AutoML processing, with the most accurate models ultimately selected for further data set analysis.

Results

Itching development for 6 months was accurately modeled using the light gradient boosted trees classifier model (log loss: 0.9302 for validation, 1.0193 for cross-validation, and 0.9167 for holdout). Pain development for 6 months was assessed using the random forest classifier model (log loss: 1.1799 for validation, 1.1561 for cross-validation, and 1.0976 for holdout). Then, the random forest classifier model (log loss: 1.3670 for validation, 1.4354 for cross-validation, and 1.3974 for holdout) was used again to estimate the DLQI development for 6 months. Finally, app use was analyzed using an elastic net blender model (area under the curve: 0.6567 for validation, 0.6207 for cross-validation, and 0.7232 for holdout). Influential feature correlations were identified, including BMI, age, disease activity, DLQI, and Hospital Anxiety and Depression Scale-Anxiety scores at follow-up. App use increased with BMI >35, was less common in patients aged >47 years and those aged 23 to 31 years, and was more common in those with higher disease activity. A Hospital Anxiety and Depression Scale-Anxiety score >8 had a slightly positive effect on app use.

Conclusions

This study provides valuable insights into the relationship between data characteristics and targeted outcomes in patients with chronic eczema or psoriasis, highlighting the potential of smartphone and AutoML techniques in improving chronic disease management and patient care.
Evaluating the Effects of a Self-Help Mobile Phone App on Worry and Rumination Experienced by Young Adults: Randomized Controlled Trial (Preprint)

BACKGROUND

Delivery of preventative interventions via mobile phone apps offers an effective and accessible way to address the global priority of improving the mental health of adolescents and young adults. A proven risk factor for anxiety and depression is elevated worry and rumination, also known as repetitive negative thinking (RNT).

OBJECTIVE

This was a prevention mechanism trial that aimed to investigate whether an RNT-targeting self-help mobile phone app (MyMoodCoach) reduces worry and rumination in young adults residing in the United Kingdom. A secondary objective was to test whether the app reduces symptoms of anxiety and depression and improves well-being.

METHODS

A web-based, single-blind, 2-arm parallel-group randomized controlled trial was conducted with 236 people aged between 16 and 24 years, who self-reported high levels of worry or rumination. Eligible participants were randomized to an active intervention group (usual practice, plus up to 6 weeks of using the RNT-targeting mobile app, n=119) or a waitlist control group (usual practice with no access to the app until after 6 weeks, n=117). The primary outcome was changes in worry and rumination 6 weeks after randomization. Secondary outcomes included changes in well-being and symptoms of anxiety and depression after 6 weeks and changes in all measures after 12 weeks.

RESULTS

Participants randomly allocated to use the RNT-targeting self-help app showed significantly lower levels of rumination (mean difference –2.92, 95% CI –5.57 to –0.28; P=.03; ηp2=0.02) and worry (mean difference –3.97, 95% CI –6.21 to –1.73; P<.001; ηp2=0.06) at 6-week follow-up, relative to the waitlist control. Similar differences were observed for well-being (P<.001), anxiety (P=.03), and depression (P=.04). The waitlist control group also showed improvement when given access to the app after 6 weeks. Improvements observed in the intervention group after 6 weeks of using the app were maintained at the 12-week follow-up point.

CONCLUSIONS

The MyMoodCoach app had a significant positive effect on worry and rumination, well-being, anxiety, and depression in young adults, relative to waitlist controls, providing proof-of-principle that an unguided self-help app can effectively reduce RNT. This app, therefore, has potential for the prevention of anxiety and depression although longer-term effects on incidence need to be directly evaluated.
