Authors: Aladesiun Olumide Temidayo , Lee Kyehwan , Song Yooseob , Park Younggil 
Published: June 2023

Abstract
Rapid and efficient cooling in injection molding leads to quality products and increased
productivity. Conformal cooling, utilizing additive manufacturing technology, is considered the
most efficient and effective cooling channel design. However, its utilization is limited due to
various factors such as complexity, cost, and lack of knowledge. While selective laser melting is
commonly used to produce cavity inserts with conformal cooling, an alternative, cost-effective
method is stereolithography. A study was conducted to investigate a hybrid design using metal
cavity inserts and stereolithography cooling channels for deflection and heat transfer analysis. A
cup-like geometry was chosen due to its heat dissipation challenges during the cooling process.
Autodesk Moldflow was employed for flow analysis to determine the injection molding
conditions, considering different cup thicknesses and material properties (PP and PC) with
varying melt flow indexes (5, 10, and 15 g/min). Finite element analysis using Solidworks
Simulation was conducted for stress analysis on selected core thicknesses (5mm, 7.5mm, and
10mm) and compared to fatigue strength. Results showed that a 5mm core thickness failed, while
the 7.5mm core thickness made of P20 tool steel was able to accommodate injection pressures
ranging from 0 to 27 MPa, averaging 461 mm³/sec. The 10mm core thickness of P20 tool steel
accommodated pressures from 0 to 45MPa, averaging 421 mm³/sec. These results were obtained
for selected PP and PC materials at melt temperatures of 230℃and 300℃, respectively,
considering cup thicknesses of 1.5mm, 2mm, and 2.5mm. A heat transfer experiment was
conducted, varying the flow rate (laminar, transitional, and turbulent) and temperature (60℃,
70℃, and 80℃) while considering two levels of diameter and pitch for the cooling channels and
core thickness. The findings revealed that higher flow rates, smaller cooling diameters, and
smaller pitch values resulted in higher thermal efficiency. The highest heat removal of 1.59 KJ
was achieved with a 7.5mm core thickness, 8mm cooling diameter, and 12mm pitch. The
analysis confirmed the suitability of stereolithography (SLA) for conformal cooling in injection
molding, highlighting the cost savings associated with adopting a hybrid design

Published: June 2023

Abstract
Introduction:
cardiac blood cyst is a very rare benign tumor of the heart in adults. Though it is very common in the first half year of life, it regresses with time and its occurrence is very rare in children older than six months and in adults. Until now less than 100 valvular blood cysts have been reported in the literature.
Case presentation:
We present a case of 66 years old male presented with right leg weakness for two weeks. He was diagnosed with a cardiac mass two months ago in another hospital. The physical examination was unremarkable. Abdominal ultrasound showed a cyst in the liver and left kidney. Echocardiography showed a mass-occupying lesion of a cystic nature in the mitral valve with mild mitral regurgitation. Based on echo findings and abdominal ultrasound report the preliminary diagnosis of mitral valve blood cyst was made. The patient underwent total endoscopic resection of the cyst. The posterior mitral cusp was repaired and a mitral annuloplasty ring was placed. The postoperative recovery was uneventful. The histopathology report confirmed the diagnosis of cardiac blood cyst. The patient was followed up for six months without any complications. This case is presented here to enrich the already available medical literature of the cardiac blood cyst.
Conclusion:
The possibility of cardiac blood cyst increases with concomitant cyst present elsewhere in the body. Though cardiac blood cyst is a rare entity in adults, it should be considered in the differential diagnosis of cardiac tumors. Because the natural history and hemodynamic effect are very diverse, large symptomatic cardiac cysts, especially in the left heart should be resected to avoid complications.
Surgical outcomes of endoscopic dacryocystorhinostomy for eyes with nasolacrimal duct obstruction via tear meniscus height evaluation
Authors: Hosoda Yoshikatsu , Matsuyama Hiroko , Akimoto Masayuki , Miyazaki Chika 
Published: June 2023

Abstract
Purpose
To evaluate clinical outcomes of patients who underwent endonasal dacryocystorhinostomy (En-DCR) and investigate prognostic factors.
Methods
We recruited 304 patients from two institutes. The tear meniscus height (TMH) was measured using anterior segment optical coherence tomography before surgery. All patients underwent endoscopic DCR with lacrimal intubation stent insertion. The lacrimal stent was removed 2 months after surgery. The TMH was measured 2 months and 12 months after surgery. Improvements in epiphora were assessed using a visual analogue scale (range, 0–2). Recurrence was determined based on lacrimal irrigation and endoscopic evaluation results.
Results
All patients experienced improvements in subjective symptoms 2 months after surgery. The mean TMH also decreased significantly compared with that before surgery. During the follow-up period, four patients experienced recurrence. The mean TMH 12 months after surgery was significantly lower than that before surgery. The rate of change in the TMH was significantly associated with the use of a dacryoendoscope during sheath-guided lacrimal stent intubation at all time points. Of the 251 patients who were followed up at 12 months after surgery, three reported recurrences, and 17 reported mild improvement of epiphora. The rate of change in the TMH was significantly associated with epiphora improvement. Height was also associated with epiphora improvement.
Conclusions
Endoscopic DCR is an acceptable surgical procedure for managing nasolacrimal duct obstruction. Sheath-guided lacrimal stent intubation using a dacryoendoscope decreases postoperative TMH more than blind insertion, which may lead to favourable clinical outcomes.

Abstract
The awareness about healthy lifestyles is increasing, opening to personalized intelligent health coaching applications. A demand for more than mere suggestions and mechanistic interactions has driven attention to nutrition virtual coaching systems (NVC) as a bridge between human-machine interaction and recommender, informative, persuasive, and argumentation systems. NVC can rely on data-driven opaque mechanisms. Therefore, it is crucial to enable NVC to explain their doing (i.e., engaging the user in discussions (via arguments) about dietary solutions/alternatives). By doing so, transparency, user acceptance, and engagement are expected to be boosted. This study focuses on NVC agents generating personalized food recommendations based on user-specific factors such as allergies, eating habits, lifestyles, and ingredient preferences. In particular, we propose a user-agent negotiation process entailing run-time feedback mechanisms to react to both recommendations and related explanations. Lastly, the study presents the findings obtained by the experiments conducted with multi-background participants to evaluate the acceptability and effectiveness of the proposed system. The results indicate that most participants value the opportunity to provide feedback and receive explanations for recommendations. Additionally, the users are fond of receiving information tailored to their needs. Furthermore, our interactive recommendation system performed better than the corresponding traditional recommendation system in terms of effectiveness regarding the number of agreements and rounds.

Published: June 2023

Abstract

Background To develop a model that could automatically predict radiotherapy sensitivity for patients with locally advanced cervical cancer (LACC) based on T2-weighted MR images and clinical parameters. Methods: A total of 138 patients were enrolled, T2-weighted MR images and clinical information of the patients before treatment were collected. Clinical information includes age, stage, pathological type, squamous cell carcinoma (SCC) level, and lymph node status. A hybrid model extracted the domain specific features from computational radiomics system, the abstract features from deep learning network and the clinical parameters, and employed an ensemble learning classifier weighted by logistic regression (LR) classifier, support vector machine (SVM) classifier, K-Nearest Neighbor (KNN) classifier and Bayesian classifier to predict pathologic complete response (pCR).The area under the receiver operating characteristics curve (AUC), accuracy (ACC), true positive rate (TPR), true negative rate (TNR) and precision were used as evaluation metrics. Results: Among 138 LACC patients, 74 were in the pCR group and 64 were in the non-pCR group. There was no significant difference between the two cohorts in terms of tumor diameter, lymph node and stage before radiotherapy, p = 0.787, 0.068, 0.846, respectively. The 109-dimension domain features and 1472-dimension abstract features from MRI image were selected to use for forming hybrid model. The average AUC, ACC, TPR, TNR and precision of the proposed hybrid model was about 0.80, 0.71, 0.75, 0.66 and 0.71, while The AUC values of using clinical parameters, domain specific features, abstract features alone were 0.61, 0.67 and 0.76, respectively. The AUC value of model without ensemble learning classifier was 0.76. Conclusions: The proposed hybrid model could predict well radiotherapy sensitivity of patients with LACC, which might help radiation oncologist to make personalized treatment plans for patients.
Why is there a gap in self-rated health among people with hypertension? A decomposition of determinants and rural‒urban differences
Authors: Mweemba Chris , Mutale Wilbroad , Masiye Felix , Hangoma Peter 
Published: June 2023

Abstract
Background
Hypertension affects over one billion people globally and is one of the leading causes of premature death. The low- and middle-income countries, especially the sub-Saharan Africa region, bear a disproportionately higher share of hypertension globally. Recent evidence shows a steady shift in the burden of hypertension from the more affluent and urban population towards the poorer and rural communities. Our study examined inequalities in self-rated health among people with hypertension and whether there is a rural‒urban gap in the health of these patients. We then quantified factors driving the health gap. We also examined how much HIV accounts for differences in self-rated health among hypertension patients due to the relationship between HIV, hypertension and health in sub-Saharan Africa.
Methods
We utilized the Zambia Household Health Expenditure and Utilization Survey for the data on SRH and other demographic and socioeconomic controls. District HIV prevalence information was from a previous study. The linear probability model provided a preliminary assessment of the association between self-rated health and independent variables. We then used the Blinder-Oaxaca decomposition to identify self-rated health inequality between urban and rural patients and determine determinants of the health gap between the two groups.
Results
Advanced age, lower education and low district HIV prevalence were significantly associated with poor health rating among hypertension patients. The decomposition analysis indicated that 45.5% of urban patients and 36.9% of rural patients reported good self-rated health, representing a statistically significant health gap of 8.6%. Most of the identified health gap can be attributed to endowment effects, with education (62%), district HIV prevalence (26%) and household expenditure (12%) being the most important determinants that explain the health gap.
Conclusions
Urban hypertension patients have better SRH than rural patients in Zambia. Educational interventions, financial protection schemes and strengthening hypertension health services in rural areas can significantly reduce the health gap between the two regions.
Influence of geogrid arrangement on the bearing capacity of a granular soil on physical models and its comparison to theoretical equations
Authors: Albuja-Sánchez Jorge , Cóndor Lino , Oñate Karen , Ruiz Shirley , Lal Dharmesh 
Published: June 2023

Abstract
This study presents an analysis of the influence of geogrid distribution on the bearing capacity of granular soils. For this purpose, the bearing capacity is compared based on 3 arrangements, uniform, trapezoidal, and inverted trapezoidal, with 2 types of geogrids, biaxial and multiaxial, under the application of an axial load. The tests performed were analyzed in three forms in which the trapezoidal distribution was the best arrangement for biaxial and multiaxial geogrids. The first analysis considers the peaks for each stress-strain curve, the trapezoidal distribution increases the bearing capacity by 36% and 33% for biaxial and multiaxial geogrids, respectively. The second analysis considers an s/B ratio of 10%, which had an average increment of 30.5% for the two types of geogrids. The third analysis considers a 20% of s/B ratio, which showed a 56% and 81% of BCR increase for biaxial and multiaxial geogrids respectively. From an economical and environmental analysis, the trapezoidal distribution saves 7% of material compared to the traditional uniform distribution. The comparison between physical and numerical models with theoretical equations is presented.
A Robust approach based on fractional variable-order Total Variation and anisotropic diffusion for Poisson image restoration
Authors: Ben-loghfyry Anouar , Yazidi Youness El 
Published: June 2023

Abstract
In this work, we propose a novel approach for Poisson image denoising based on a fractional variable-order total variation functional combined with an anisotropic diffusion operator. Poisson noise is particularly challenging to remove since it depends heavily on the image intensity. Due to the region geometry in images, efficient regularization terms capable of preserving piecewise smoothness in details and features such as Total Variation technique are necessary. The proposed model is discretized, and the Alternating Direction Method of Multipliers algorithm is used to split our optimization variables. We conduct various numerical experiments to demonstrate the superiority of our proposed approach over state-of-the-art methods in Poisson image denoising.

Published: June 2023

Abstract
The use of toxic and persistent pesticides in agriculture results in serious and lasting environmental impacts. Although traditional methods such as physical and chemical reclamation give the best results, treating these contaminants requires high cost and expertise. Therefore, this study focuses on bioremediation recovery, which is more efficient, economical, and safer to remove. In this case, the newly isolated potential of Pichia kluyveri FM012 in degrading 4-bromophenol was investigated. The selected strain was isolated from the tropical rainforest in Selangor, Malaysia. The impact of optimized parameters such as agitation, pH, nitrogen and carbon source were also studied. After extensive testing, the best optimal degradation was at pH 5 with 150 rpm stirrer speed. Glucose and yeast performed best compared to other carbon and nitrogen sources. The maximum biosorption capacity (qm = 38.46 mg/g biomass) was predicted by the Langmuir model, but the Freundlich model adsorption gave a better value of R2 = 0.999. The pseudo-second-order kinetic model fits the study of biosorption kinetics. The FTIR spectrum revealed the presence of asymmetric and symmetric vibration of the aromatic ring and was assigned C=C or C=O, and fungi showed biosorption ability in broad functional groups. These results provided interesting information about the ability of Pichia kluyveri FM012 and potential applications to remediate the resistant pesticide.
Bifurcation and stability of uniformly rotating homogeneous ellipsoids surrounded by a massive thin ring
Authors: Yoshida Shin'ichirou 
Published: June 2023

Abstract
We examine the effects of a massive concentric ring around a spheroid or an ellipsoid with uniform density and uniform rotation. Equilibrium sequences of axisymmetric Maclaurin-like spheroid and triaxial Jacobi-like ellipsoids are obtained. Due to the gravitational field of the ring, Maclaurin-like spheroid does not have a spherical limit when the object's angular frequency vanishes. At a critical value of the eccentricity of the spheroid's meridional section, a triaxial Jacobi-like ellipsoid bifurcates. When a parameter characterizing the gravitational field of the ring is smaller than a threshold, the bifurcation points of Maclaurin-like and Jacobi-like ellipsoids exist and the critical eccentricity is slightly larger than that of the classical Maclaurin-to-Jacobi bifurcation. When the parameter exceeds the threshold, the Maclaurin-like spheroid does not have the bifurcation point and the Jacobi-like ellipsoid appears at the lower eccentricity than the Maclaurin-like spheroid. By comparisons of the energy of the ellipsoids with the same angular momentum, it is shown that the critical point of bifurcation does not correspond to the onset of the secular instability of Maclaurin-like spheroid. It is concluded that the gravitational field of a massive ring surrounding a uniformly rotating spheroid stabilizes it against a bar-shaped deformation due to viscous dissipations.
Urban Parks for Conservation of Butterflies: A case study of Butterfly Diversity of Urban Parks in Kozhikode urban agglomeration, Kerala
Authors: Alex Naveen Prasad 
Published: June 2023

Abstract
In Southeast Asia, urbanisation and biodiversity loss have accelerated due to rapid economic development. However, the conservation value of urban parks in India remains understudied. In the Kozhikode Urban Agglomeration, we examined the diversity and richness of butterflies and its relation with area of the park and distance of park from city centre. At each park, butterfly surveys were carried out across various microhabitat types: Groves, hedges, flowerbeds, and unmanaged areas make up the first four categories. The vegetation use and behaviour of butterflies were also studied. The conservation interest and endemicty of the butterflies were also noted. We recorded 74 species of butterflies from 6 families, some having some sort of endemicty and conservation interest. The area of the park was moderately positively correlated with the diversity and richness whereas the vice versa was seen for distance from city centre. Regarding microhabitats the highest species richness and diversity was observed for unmanaged and groves microhabitats. The results revealed that even though there are limitations with proper planning and implementation, urban parks can serve as a good conservation effort.

Authors: Robo Ilma , Kapaj Kers , Cafaj Migerta , Heta Saimir 
Published: June 2023

Abstract
Background
Bacterial plaque with diverse content of different types of bacteria, has a well-organized structure and functions as the main pathogen of periodontal pathologies, based on this regular structure. Despite the specific bacterial content, which is individually variable, the plaque has the possibility of causing periodontal pathology that in some clinical specifics, may not even cause periodontal pathology; all this depending on the immunity of the individual or the patient.
Main text
The etiological factors of bacterial plaque in the literature are also classified as retentive factors, or factors that help in the creation or maturation of bacterial plaque. The basic principle of these factors is the creation of rough surfaces on which the bacterial plaque is created according to the stages of initial colonization, adhesion, secondary colonization and maturation. This study aims to present these factors according to clinical cases, and to numerically evaluate the data collected from the evaluated patients.
Conclusions
Prophylaxis against periodontal diseases must first include the patient's understanding of the pathogenic role of bacterial plaque and how to prevent its adhesion and maturation.
