Published: December 2023

Abstract
The elaboration of a masonry block reinforced with coconut fiber and peanut shells is the focus of this research work. The fibers are obtained after the harvest, which, due to poor management of the disposal of these agricultural residues , pollute the environment by their free decomposition and open burning, producing greenhouse gases. This sustainable material formation will also contribute to reducing the carbon footprint produced by buildings during their lifetime , which requires a high consumption of energy and raw materials. Three 10 cm x 20 cm test cylinders were made, composed of coconut fiber and peanut shells agglomerated with cement, which were submerged in water for 28 days for curing, of which the best compressive strength was 20.33 kg/cm2.

Abstract

Background Glaucoma describes a group of ocular disorders with multi-factorial aetiology characterised by raised intraocular pressure and associated optic neuropathy. Globally, it is the leading cause of irreversible blindness. Several studies on clients’ adherence to medications have shown that many clients do not adhere to medication regimens, and this is a significant factor leading to the various complications of the disease. This study determined the factors that influenced the adherence of glaucoma patients to topical eye drops in Ho Teaching Hospital (HTH).Methods This cross-sectional study involved glaucoma patients aged 18 years and above on topical eye drops who attended the eye clinic of HTH. The questionnaires administered obtained data from the patients and exported to STATA version 16 for cleaning and analysis at a significant level of 0.05.Results More than half (59.7%), 25.8% (32) and only 14.5% (18) showed low, moderate, and high adherence, respectively. There was a significant association between clients’ response to glaucoma leading to blindness, glaucoma treatment preventing complications and adherence (χ2 = 6.25, p = 0.044) and (χ2 = 6.26, p = 0.044), respectively. The length of glaucoma medication usage (χ = 25.29, p = 0.001), number of drugs (χ 2 = 15.25, p = 0.002), distance from the place of residence to the hospital (x2 = 10.02, p = 0.007), coming for regular review (x2 = 33.81, p = < 0.001) and number of times medication is applied to the eye per day (χ 2 = 15.95, p = 0.001) were statistically associated to adherence to glaucoma medication.Conclusion The level of adherence to medication among respondents was low. Factors influencing medication adherence included proximity to the health facility and reporting for regular reviews. Having glaucoma, being on medication over a more extended period and providing further clarification on the drug regimen influenced the adherence rate among respondents. We recommend that health workers offer detailed and clear instructions on instilling medication to improve glaucoma medication adherence.

Abstract
Background
Coronavirus disease 2019 (COVID-19) pneumonia and anti-melanoma differentiation-associated gene 5 antibody-positive interstitial pneumonia (MDA5-IP) share many similarities; however, the treatment and management of the two diseases are different. In the early stages of developing a treatment plan, it is crucial to distinguish between the two diseases. This study was conducted to compare the radiological findings between COVID-19 pneumonia and MDA5-IP.
Methods
We recruited patients with COVID-19 pneumonia between January and June 2020. The control group comprised patients with MDA5-IP admitted between April 2013 and December 2019. Patients with thin-slice computed tomography (CT) images within 2 days of admission were enrolled. The CT images were analyzed using an artificial intelligence-based quantitative CT software program. Radiological findings were classified as faint ground-glass opacity (GGO), GGO, reticulation, consolidation, honeycombing, nodules, hyperlucency, or interlobular septum. The volumes of these radiological findings were compared between the two groups. A classification and regression tree algorithm was used to develop a prediction model to stratify the risk of COVID-19 pneumonia.
Results
We enrolled 72 and 15 patients in the COVID-19 pneumonia and MDA5-IP group, respectively. Faint GGO and consolidations were observed more extensively in patients with MDA5-IP. The prediction model was developed at cut-off values of faint GGO, < 30%; GGO, ≥ 10%, and consolidation < 1%. This prediction model contributed to changing post-test probability in 26% of cases.
Conclusion
The COVID-19 group showed fewer faint GGO and consolidation volumes than the MDA5-IP group. We developed a predictive model to stratify the risk of COVID-19 pneumonia.

Authors: Singh Gurbinder , Wague Aboubacar , Arora Ayush , Rao Varun , Ward Derek , Barry Jeff 
Published: December 2023

Abstract
Background: This study conducted an analysis examining clinical trial discontinuation rates, associations between intervention types and discontinuation/nonpublication, and the role of funding, enrollment size, and their implications for trial success and completion.
Methods: We analyzed ClinicalTrials.gov on May 1, 2023, for phase 3 and 4 randomized controlled trials (RCTs) pertaining to orthopaedic oncology. Trial completion status was assessed using publicly available data on ClinicalTrials.gov. Publication status was also assessed on ClinicalTrials.gov, and by utilizing PubMed (MEDLINE, Google Scholar, and Embase).
Results: Among the cohort of 130 trials, 19.2% were prematurely discontinued. Completion rates varied based on intervention type; 111 pharmaceutical trials demonstrated a completion rate of 83.8%, whereas 19 non-pharmaceutical trials exhibited a completion rate of 8.0% (P<.001). Surgical trials, totaling 10, showed a completion rate of 90%. The overall trial publication rate was 86.15%, with pharmaceutical interventions achieving a publication rate of 91.96%. Larger-scale trials (≥261 participants) emerged as a protective factor against both discontinuation (Adjusted Odds Ratio [AOR]: 0.85, 95% Confidence Interval [CI]: 0.42–0.95) and nonpublication (AOR: 0.19, 95% CI: 0.13–.47), compared to smaller-scale trials.
Conclusion: Our examination of orthopaedic oncology clinical trials underscores the imperative to confront the challenges linked with trial discontinuation and nonpublication. This study accentuates the heightened vulnerability of non-pharmaceutical interventions and trials exhibiting lower rates of enrollment to the issues of discontinuation and nonpublication. Moving forward, the advancement of clinical trials necessitates a concerted effort to enhance trial methodologies, especially concerning nonpharmaceutical interventions, along with a meticulous refinement of participant enrollment criteria.
Experimental Study on Shear Resistance of Steel Plate Girder End Panels
Authors: Hingnekar Durgesh R. , Vyavahare Arvind Y. 
Published: December 2023

Abstract
This paper presents an experimental investigation into the effect of the geometric design parameters, such as web slenderness ratio and end post rigidity, on the shear resistance behaviour of steel plate girder end panels. Nine different girders specimens with different end post rigidities and web slenderness ratios were loaded in shear and tested until collapse. With the help of state-of-the-art deformation and strain measurement techniques, this study generates novel experimental data, providing additional critical information enabling us to understand the shear resistance behaviour of the end panels with a fresh perspective, which is different from the commonly used classic shear design models. The girders with no end post and non-rigid end post also displayed significant postbuckling strength. Also, it was found from the experimental results that the effect of the end post rigidity was more prominent on the shear resistance of slender end panels than on semi-compact end panels. The existing design models were also evaluated with 27 relevant test results available in the literature and 9 test results reported in this paper.

Authors: Luo Fanyan , Bu Haisong 
Published: December 2023

Abstract
Complete transposition of the great arteries (TGA) is a common life-threatening complex cyanotic congenital heart disease in infants, resulting in the operation is usually performed about one week after birth. However, little is known about the surgical strategy and experience of TGA with an intact ventricular septum in older patients. Herein, we present an abandoned 7-year-old boy with severe cyanosis with clubbed fingers and toes and then diagnosed as dextro-TGA with an intact ventricular septum, atrial septal defect, patent ductus arteriosus (PDA), and pulmonary hypertension. The patient was performed a two-staged procedure, the aortopulmonary shunt and pulmonary artery banding were performed at the first stage, and then the Switch operation, defect repair, and PDA ligation were successfully performed. The patient was discharged on the 15th day after the operation, and the arterial oxygen saturation returned to normal level (99%). The illustrative report highlights the essence of improving the raising awareness and accurate treatment strategy of dextro-TGA, especially for the remote rural areas of eastern countries where the level of health care and services is relatively backward.
A two-channel end-to-end network based on dynamic corpus of knowledge graph for intelligent recognition of Traditional Chinese Medicine terminology
Authors: Wu yulu , Wang kun , Liu Xiufeng 
Published: December 2023

Abstract
The accurate analysis of Traditional Chinese Medicine (TCM) terminology is a research hotspot in the field of TCM, as it can provide a convenient way of information exchange between TCM and patients, thus achieving accurate diagnosis and treatment. TCM terminology includes two forms: speech and text. Currently, the methods used for TCM terminology recognition often adopt deep learning models. However, the existing deep learning methods are hindered by insufficient corpus and defects of the end-to-end learning framework, which leads to the low accuracy of TCM terminology recognition. To solve the above problems, this paper first combines the information of text and picture of TCM terminology and proposes an extended model of TCM terminology corpus. Joint optimization of text and picture-based knowledge graph TCM terminology corpus expansion model is incorporated, and the traditional corpus is supplemented by incrementally constructing a dynamic TCM terminology corpus. Secondly, the text-speech end-to-end conversion mechanism is used to realize the synchronous incremental expansion of the TCM dynamic speech corpus. After that, the TCM dynamic speech corpus is deeply trained through a unified streaming and non-streaming two-pass end-to-end model, to realize the accurate recognition of the speech of TCM terminology. Due to the language habits of TCM experts, there are many redundant words in TCM pronunciation, which greatly reduces the readability of the text of TCM terminology. In this paper, we proposed a directed acyclic graph-(DAG) and dynamic programming-(DP) based redundant word detection framework to screen redundant words and realize the accurate identification of TCM terminology. The results show that the accuracy of the speech recognition algorithm proposed in this paper for the speech of TCM terminology is increased by 12.92%, 11.18%, and 19.95% compared with three public speech recognition engines of Iflytek, Aliyun, and Baidu, respectively. As an incremental contribution, this paper optimizes the redundant words based on speech recognition, which greatly improves the ability to conformant TCM terminology.
Research on the Aerodynamic Performance of the External Windshield of High-Speed Trains Operating on Open Lines
Authors: JIN Yongrong , CHEN Xiaoli 
Published: December 2023

Abstract
The proportion of aerodynamic resistance in train operation resistance is increasing as the speed of the train continues to increase. A streamlined front can reduce train running resistance effectively. Windshields and pantographs cause sudden changes in the geometric shape of the train's longitudinal section also have a significant impact on train running resistance. High-speed trains generally use external windshields, which can reduce the impact of sudden changes on the running resistance to geometric shape of the train end connection. The article constructs a 3-group calculation model based on the true geometric shape of high-speed trains to study the aerodynamic drag reduction effect of the external windshield with three-dimensional, steady, incompressible N-S equations and k-ε are adopted to calculate the flow field distribution and pressure distribution of the external windshield of trains operating on open lines at a speed of 250km/h, 300km/h, 350km/h, 400km/h or 450km/h separately. The aerodynamic resistance and lift of the external windshield were fitted, although the train operating speed changed, it was a variation curve.

Abstract
Anaerobic digestion is considered a versatile process that for years has been used to treat various types of waste. Besides being a low-cost technology applicable in rural and urban locations, anaerobic digestion produces multiple by-products that can be integrated into a biorefinery scenario. Similarly, microalgae biotechnology can adequately complement anaerobic digestion by improving resource recovery through a closed-loop process and contributing to a biobased green circular economy model. Therefore, this chapter aims to address current perspectives on the topic. It covers algae cultivation from anaerobic digestion residues as a post-treatment option and digestate as a potential medium for microalgae growth. Moreover, anaerobic digestion is presented as an energetic valorization route of algae biomass, including strategies to overcome main challenges, such as pre-treatment of microalgae biomass and anaerobic co-digestion. Biogas upgrading during algae cultivation is also discussed. Finally, it presents biorefinery models based on integrated microalgae and anaerobic digestion, reporting the technologies’ sustainability and environmental impacts. Future perspectives on the subject are highlighted, encouraging further studies to improve microalgae biomass production, nutrient recovery, wastewater treatment, and biogas upgrading.
A Comparative Study of Different Unorganized Sectors’ Workers in India
to Identify Musculoskeletal Disorder Prevalence through Empirical
Survey and Deep Learning Methods
Authors: Meena Arvind , Jain Rahul , Kumar Yadav Anant , Kumar Vikram , Meena Abhishek , Bihari Rana Kunj , Lal Meena Makkhan , Kumar Jindal Manish 
Published: December 2023

Background::
Musculoskeletal disorders (MSDs) are a group of non-fatal injuries that
can occur as a result of various repetitive workplace activities, mainly in unorganized sectors.
Workers who engage in highly repetitive activities involving constant hand effort, localized mechanical
pressure, and vibration are more prone to developing these disorders.

Objective::
The objective of this research was to determine the prevalence of MSDs among workers
in various unorganized sectors in India who perform hand-intensive occupations.

Method::
A cross-sectional study was conducted, involving 340 workers from diverse groups such
as sugarcane farmers, footwear industry workers, and tarpaulin weavers, to accomplish this goal.
Data for the survey was collected using a questionnaire. Additionally, a comprehensive time study
and a deep learning-based posture detection study were conducted on the different activities performed
during the workers' occupational tasks. The chi-square test was used to assess the relationship
between discomfort and work repetitiveness.

Result::
The data analysis revealed that the working activities (especially cutting/harvesting, rubber
cutting, etc.) of unorganized sector workers were repetitive, with more than half of each activity’s
work cycle involving a similar usage pattern. Furthermore, a significant association was
observed between the level of discomfort and work repetitiveness among workers in different sectors
(sugarcane farmers: p < 0.01, footwear industry workers: p < 0.05, tarpaulin weavers: p <
0.05). Consequently, it can be concluded that prolonged occupational activities involving repetitive
and prolonged standing may contribute to the occurrence of MSDs.

Conclusion::
Ergonomic interventions/modifications in the form of patent work will be necessary
to prevent these issues in the near future.
Activation Energy Rechargeable Prussian Yellow Nano Film Electrode
using Hydrated Ions
Authors: Baioun Abeer , Kellawi Hassan 
Published: December 2023

Aim:
Interfacial charge transfer is a fundamental issue in both the science and technology
of the batteries. In this work, the activation energy for the interfacial charge transfer, Ea, though PY
thin film was estimated by measurement measurements of electrochemical impedance spectroscopy
(EIS) for both monovalent and multivalent hydration cations: Li+, Na+, K+, Ca+2 and Mg+2 in aqueous
electrolytes.

Background:
Rechargeable batteries have become quintessential energy conversion devices that are
widely used in portable electronic devices and hybrid electric vehicles. PB and its analogues have
open channels that allow rapid insertion/extraction of different cations and that lead to a long cycle
of its in such as batteries (Na+, Li+ and K+).

Objective:
preparation of Prussian yellow Nanofilm on ITO glass by a simple chemical facial method
and study of its charge/discharge processes of intercalation compounds in rechargeable features.

Methods:
The electrochemical measurements of potentiostat/galvanostat cyclic voltammograms and
EIS were carried out in three-electrode cells, with Ag/AgCl as a reference electrode. Pt. and ITO|PY
as working and counter electrodes respectively. The electrolytes were solutions of 0.1 M+z cation in
water where M+z was one of the following cations: Li+, Na+, K+, Ca+2 or Mg+2.

Results:
The effect of hydration on the activation energy for the PY thin film was studied by the EIS
at different temperatures. The ions K+ have an activation energy interfacial, which is lower than that
of Na+ and Li+. So the coulombic repulsion at the interface is largely suppressed by the screening effect
of ions hydration, explaining the small values of Ea with aqueous electrolyte. Furthermore, the
hydration helped the Ca+2 and Mg+2 intercalation in PBA but with large values of Ea that were due to
coulombic repulsion at the interface.

Conclusion:
Prussian blue can be considered among the most promising cathode materials for energy
storage batteries because of their rigid open framework with large interstitial sites that can pertain
to mono and bivalent cation mobility and accommodate volume variation during ions insertion/
extraction.
Modal Analysis and Optimization of Fluid-Structure Coupling for Rotor
and Inner Cylinder of Vertical Condensate Pump
Authors: He Xiaofeng , Liu Xiaofeng , Ma Yunxiang , Lu Chengbin , Wu Yang , Nie Zhongfu 
Published: December 2023

Background:
Low-frequency resonance is one of the common issues encountered during
the variable-frequency operation of condensate water pumps. There have been numerous patents and
papers proposing solutions to address the low-frequency resonance problem in condensate water pumps.
However, the solutions for resonance problems often need to be tailored to specific circumstances.

Methods:
Based on the acoustic method, the dynamic model of the rotor and inner cylinder of Jiangsu
Guohua Chenjiagang Power Plant 2B condensate pump is established to compare the difference
between dry modal and fluid-structure coupling modal, the influence of perpendicularity, concentricity
and bearing wear on the natural frequency of rotor is studied.

Results:
The rotor is rigid under normal conditions. When the bearing is worn, the frequency of the
rotor will be greatly reduced and may fall into the frequency conversion operation range to excite
resonance. The deviation of perpendicularity and concentricity will not directly lead to the decrease
of rotor modal but will lead to the increase of bearing stress, aggravate bearing wear, and then affect
the rotor modal. As the inner cylinder only relies on the fixed support at the top, the structure stiffness
is low, which may lead to low-frequency resonance. By adding two support structures at the
guide vane, the first-order modal frequency of the inner cylinder can be increased from 3.29 Hz to
28.88 Hz, effectively avoiding the operating frequency range of the system.

Conclusion:
This study can guide the optimization of similar pump structures.
