Numerical structural analysis using the finite element method has be-come standard in modern machine and equipment design processes. Increasingly, not only the strength or stiffness of the structure is verified, but also the selection of geometric features in optimisation analyses is performed in an automated man-ner. The paper deals with the problem of topological optimisation of the supporting frame of a 20-foot office container at the initial stage of geometric feature selection. The computations were performed in the ANSYS Workbench environment. Four load cases were formulated according to the operating conditions of the container. The objective function for the analyses was to achieve a minimum mass. Con-straints defining the set of good solutions were also adopted for the analyses. These constraints included excluding from the analyses those areas of the model where boundary conditions were applied and limiting the maximum dimensions of the frame cross sections. On the basis of the analyses, a numerical model of the frame that was considered optimal in terms of maximum weight loss was indicated. For this variant, a geometric shape of a frame composed of standardised sections was proposed. The frame obtained in this way was subjected to a computational verifi-cation in terms of structural strength for the boundary conditions resulting from the previously assumed load cases. The work demonstrates the effectiveness of top-ological optimisation using the SIMP method for the analysis of frame structures.

Authors: Noordyanto Naufan , Sayatman
Published: June 2024

This research aims to design a new typeface that reflects the characteristics of the Institut Teknologi Sepuluh Nopember (ITS) campus and can be used in a variety of contexts. The new typeface, ITS-Artistech, was created by synthesizing key features into the anatomy of Latin letters, which were extracted from the key characteristics and images of the ITS campus. The typeface is intended to be one of several typographic options that reflect ITS and to pioneer typeface production at ITS, contributing to the theoretical and practical body of knowledge on designing typefaces that reflect campus identity. The research method involved collecting data on the use of typefaces in the ITS environment and ITS profile, conducting perceptual studies to know how people perceive the images and characteristics of the ITS campus, and developing the typeface through a series of iterative refinement steps. The new typeface is a valuable resource for the ITS community, as it helps to promote the university's brand, foster a sense of community, and support the creative process and the research of typeface design. It is also a unique and distinctive typeface that is not based on any preexisting letters. The typeface is available as a digital letterform (font) that can be installed and used for a variety of purposes, including digital and print promotional materials.

The Recombinant NS3 Protein a Potential Antigen for Dengue Vaccine Development
Authors: Bartutis* Rosa Ramirez
Published: June 2024

The NS3 protein is a multifunctional non-structural protein involved in dengue virus polyprotein processing. This protein is also target in the immune response against dengue virus infection. The predominance of cytotoxic T-cell lymphocytes epitopes in the NS3 structure suggests the participation of this protein in limiting virus replication and in the protection against dengue disease. A brief presentation on aspects related to antigenic characteristics and immunogenicity of the recombinant NS3 protein is reported in this work. A reduced number of studies have assessed the NS3 protein in a dengue vaccine formulation. Researches carried out in mice shown that DNA vaccines based on NS3 protein induced a protective response evaluated by their ability to produce IFNγ. Moreover, the incorporation of recombinant subunit NS3 in a purified inactivated vaccine significantly increased the immune response induced by this inactivated vaccine. Likewise, recent studies demonstrated that the combination of the recombinant modified-NS1 and NS3 proteins from dengue 2 virus induced higher immune responses and protection in mice. The immunological studies discussed herein support the possible inclusion of the NS3 protein in a dengue vaccine formulation.
N95 Respirator Fit Testing Experience during the Pandemic at a Singapore Tertiary Health Institution: Streamlining Workflow and Improving Respirator Fit Rate
Authors: Cuixia Wang , Wong Sharon , Mohamed Abdul Wahab Nurhuda Binte , Koh* Sabrina
Published: June 2024

The N95 respirator is imperative for Healthcare Professionals (HCPs) when caring for patients with potentially airborne infectious diseases such as COVID-19. During the onset of the COVID-19 pandemic, HCPs were anxious and unsure if their N95 respirator still fits well. In addition, as a result of the sharp increase in demand and consequent supply disruptions for some N95 respirator models, alternative respirator models were sourced and brought in at different intervals. The Infection Prevention & Control Department (IPCD) had to react to the situation by conducting impromptu mass fit testing sessions for affected HCPs. Quick turnaround strategy using online pre-registration for respirator fitting had helped to make the N95 respirator fit test procedure more seamless. The introduction of quantitative fit testing had also enhanced the success rate of fitting, with the majority of HCPs previously could not be successfully fitted with a N95 respirator, being now successfully fitted.

Published: June 2024

Mitochondria are double-walled organelles that generate energy in the form of ATP. ATP is an energy-rich compound and a driver of fundamental cell functions. Mitochondria-oriented studies help design advanced therapies to target lung cancer. Lung cancer is the leading cause of cancer incidences and death globally. Various studies have supported that mitochondrial function is disrupting cancerous cells. Mitochondrial dysfunctions lead to dysregulated ATP synthesis, disturbed respiratory chain, unbalanced mitochondrial fission or fusion, disturbed cellular redox homeostasis, dysregulated apoptosis, and interfered non-smooth intracellular calcium signaling. Dysfunction mitochondria are associated with cancer cell proliferation, metastasis, and death. In this review, we have tried to elaborate on how normal cell mitochondria function differently from the mitochondria of lung cancer cells. It includes various targets such as mitochondrial proteins and related pathways, along with new drug molecules like Militarin analog-1, Dihydromyricetin, and papuamine. As mitochondrial metabolism is associated with the proliferation and metastasis of lung cancer cells, finding interlinks between malfunctioning mitochondria and the process of lung cancer can promote the development of new treatments.

Authors: Dhingra Sunil , Sharma* Vinod Kumar
Published: June 2024

Ever increasing use of fossil fuels such as coal and oil, contributing significantly to global warming and a great deal of harm to the environment. It is of utmost necessity to develop green sources of energy not only to generate power but most importantly to reduce the impact of energy production on the environment. In addition to the climate challenges, we are now facing challenges related to high energy prices and the high risk of supply shortages. Energy and, in particular, the clean energy is an important topic that needs special attention by the scientific community World-wide and, more so, in the context of the developing countries. Renewable energy should be looked as the most important instrument for the socioeconomic development, eradication of poverty and unemployment and an instrument of rural development. Amongst potential renewable energy sources, biomass can play an important role in achieving a net-zero carbon emissions and can be used to produce electricity, transportation fuels, or chemicals. Development of small to medium size technologies for power production in order to allow the exploitation of low value feedstocks, such as biomass residues from forest management, agro-industrial, agricultural sectors and wood industries, are of importance, especially in the context of the developing country, like India. It is in the above context that to address many challenges, such like biomass collection, processing, storage and its transportation to the point of ultimate utilization an important idea to develop decentralized model involving Farmer Producer Organizations (FPOs), farmers cooperatives, etc. in production of crop residue pellets or terrified pellets at village level, has been discussed in the present paper.
Statement on Impact of Air Pollution on Human Health; Africa Region
Authors: Leopold* Rusizana
Published: June 2024

The impacts of air pollution on human health are enormous and in African region, morbidity and mortality from air pollution causes rose since 1990. The significant sources of air pollution have been observed from human activities such as Industrialization, agricultural burning, transport and traffic, combustion of wood, coal, paraffin and animal dung for household energy needs, dusty roads and burning of household solid waste in areas without regular residential waste collection services. Africa with a poor health system faces a severe lack of air pollution detection metrics, with only 7 out of 54 countries having air quality detection monitors. Long- and short-term exposure to air pollution is associated with increasing rate of morbidity and mortality from acute and chronic respiratory diseases, cardiovascular diseases and cancers. The progression of asthma, lung cancer, cardiovascular diseases, Alzheimer's and Parkinson's diseases is linked to air pollution exposure. Measures to reduce and control air pollution in Africa Region have been suggested in this paper.

Published: June 2024

Thyrotoxicosis is a clinical condition associated with excessive thyroid hormone levels. Symptoms can range from asymptomatic to life-threatening due to thyroid storm. Thyrotoxicosis in hydatidiform moles is a rare condition but has a high mortality rate, so etiological studies are still needed for optimal management. Case Report: Patient Mrs. T, 25 years old Hindu, Balinese, 12 weeks pregnant (Gravida 1 Para 0 abortion 0), came to the obstetrics ER on September 24, 2023 with complaints of discharge from the birth canal since the morning, nausea (+), often shaking, easily tired and often sweaty. physical examination obtained blood pressure 100/60mmHg, pulse 78x/min, respiratory rate 20x/min, axillary temperature 36.80C oxygen saturation 99%. From obstetric examination, fundus uteri height ½ center, vaginal toucher vulva vagina within normal limits, portiono (-) fluxus (+), laboratory examination obtained HCG 387,392.8 mIU/m, FT4 31.05 pmol/L (N: 9-22), TSH <0.01 uIU/mL (N: 0.4-4.2) ultrasound results describe honey comb appearance and histopathology results describe partial mola.  Evacuation by curettage was performed, resulting in reduced serum ?-hCG levels and reduced thyroid hormone levels. Discussion: The patient was diagnosed with partial hydatidiform mole and thyrotoxicosis. Hydatidiform moles can cause thyrotoxicosis. This condition is caused by the structure of ?- hCG which resembles TSH so that it can activate TSH receptors.  After evacuation of hydatidiform moles, normal TSH and FT4 levels will be obtained. Conclusion: The female patient with thyrotoxicosis due to hydatidiform moles had the moles evacuated, resulting in normal thyroid hormone levels.

The distribution of stellar obliquities provides critical insight into the formation and evolution pathways of exoplanets. In the past decade, it was found that hot stars hosting hot Jupiters are more likely to have high obliquities than cool stars, but it is not clear whether this trend exists only for hot Jupiters or holds for other types of planets. In this work, we extend the study of the obliquities of hot (6250–7000 K) stars with transiting super-Earth-sized and sub-Neptune-sized planets. We constrain the obliquity distribution based on measurements of the stars’ projected rotation velocities. Our sample consists of 170 TESS and Kepler planet-hosting stars and 180 control stars chosen to have indistinguishable spectroscopic characteristics. In our analysis, we find evidence suggesting that the planet hosts have a systematically higher

〈

i
〉

compared to the control sample. This result implies that the planet hosts tend to have lower obliquities. However, the observed difference in

〈
sin
i
〉

is not significant enough to confirm spin–orbit alignment as it is 3.8σ away from perfect alignment. We also find evidence that within the planet-hosting stars there is a trend of higher obliquity (lower

〈

) for the hotter stars (T
eff > 6250 K) than for the cooler stars in the sample. This suggests that hot stars hosting smaller planets exhibit a broader obliquity distribution (

) than cooler planet-hosting stars, indicating that high obliquities are not exclusive to hot Jupiters and instead are more broadly tied to hot stars.

Milne Edwards, 1853, based on a variation of the angulation of the gonopod apex. These species are distributed along rivers and lakes in northern South America, with disjunct occurrences in central-west Brazil and Argentina. Due to these inconsistencies, an integrative approach was performed to elucidate these questions, with morphological (including NanoCT-Scan) and molecular analysis (Maximum Likelihood Trees, Bayesian Inference, Genetics Distance Matrix, and Haplotype Network), based on mitochondrial markers COI and 16S rRNA. Both analysis revealed and supported the existence of a species complex under the name ofD. septemdentatus. Based on the results obtained, we propose the revalidation ofD. spinifer, the description of a new species, and the redescription ofD. septemdentatuss. str., with a neotype designation for this species. The hypothesis that this species complex originated in the Pebas System, an extensive mega wetland system that existed along the lowlands of Western Amazonia from late Oligocene to late Miocene (c. 23–11 mya) is discussed.

The muscid genus Achanthiptera Rondani (Diptera: Muscidae) was classified within its own subfamily Achanthipterinae for decades due to a misinterpretation of adult morphology. Conversely, the larval morphology suggested that Achanthiptera should be classified within Azeliinae, yet no formal changes were implemented based on this source of data. Using scanning electron microscopy (SEM) and confocal laser scanning microscopy (CLSM), we examined the larval morphology of Ac. rohrelliformis (Robineau-Desvoidy), Potamia littoralis Robineau-Desvoidy and Australophyra rostrata Robineau-Desvoidy. Despite the challenges posed by the poor condition of hundred-year-old museum specimens of Ac. rohrelliformis for light microscopy, CLSM examination yielded satisfactory results. Additionally, CLSM observations revealed peculiar modifications to the cephaloskeleton, including a dome-shaped (second instar) or spade-like (third instar) anterior rod attached to each mouthhook in Ac. rohrelliformis and P. littoralis. These structural modifications are likely to enhance the efficiency of food collecting by enlarging the surface of the mouthhooks. The results of our morphological analyses lead to the conclusion that larvae of Au. rostrata are facultative carnivores, while modified accessory oral sclerites in Ac. rohrelliformis and P. littoralis suggest a saprophagous feeding strategy. This study contributes new evidence that Achanthiptera is the sister taxon to Potamia Robineau-Desvoidy, and both are nested within the subfamily Azeliinae.

The intersection of climate change and food production is emerging as a critical area of research, focusing on both the potential benefits and the significant challenges posed by changing climate conditions. Elevated levels of carbon dioxide alongside rising global temperatures could theoretically boost crop yields, benefiting both human and animal consumption. This study examines the impact of various climate variables—temperature, humidity, precipitation, and soil moisture—on the primary production of essential foods such as rice, wheat, livestock, milk, eggs, vegetables, and fruits. Utilizing data from different countries spanning from 2000 to 2020, drawn from world development indicators, this research employs econometric analysis coupled with deep learning-based cluster analysis. Additionally, it projects future production trends up to 2100 using the moving average time series forecasting method. The findings reveal a direct correlation between climate variables and the production levels of vegetables and other food items, highlighting the immediate effects of climatic changes on agriculture. The study also points out the uneven distribution of these climate impacts, with developing countries facing more severe challenges due to their limited resources and adaptive capacities. This uneven impact contributes to increased uncertainty in food supply and affects market stability. Furthermore, concerns about food safety are intensifying under the influence of climate change, although some regions have implemented effective food conservation and control measures to mitigate these risks. This research underscores a complex landscape where the risks and benefits of climate change on food production are not uniformly distributed, but rather are influenced by a myriad of factors including geographic location, economic conditions, and the level of technological advancement in food safety practices. The nuanced understanding of these dynamics is crucial for developing targeted strategies to enhance food security in the face of a changing climate.
Anti-angiogenesis efficacy of the aqueous extract of Allium sativum and its combination with melatonin in an animal model: in vivo and ex vivo studies
Authors: Obaid Khalid Ali
Published: June 2024

To better understand Allium sativum’s anti-angiogenesis activity, we undertook this study to examine its effect on the ex vivo rat aortic ring and the in vivo chick chorioallantoic membrane. Additionally, we compare Allium sativum’s anti-angiogenesis activity to melatonin and study the benefits of their combination. The study included six albino male rats (aged 5–7 weeks). The rats were euthanized, and then the thoracic aorta was removed and cut into rings that were 1 mm thick. The study was divided into three groups: a negative control (1% v/v DMSO), a positive control (100 μg/mL melatonin), and an aqueous Allium sativum extract. The test compounds were subjected to serial dilutions to obtain 100, 50, 25, 12.25, and 6.25 μg/mL concentrations. In addition, the in vivo chick chorioallantoic membrane was also undertaken. Allium sativum and melatonin significantly inhibited the rat aorta ring; the IC50 was calculated (IC50 = 8.04 for Allium sativum and 3.313 for melatonin). The zone of inhibition for melatonin, Allium sativum, and the combination showed that the combination had the strongest effect on the CAM assay. This zone scored (++) and (+++), respectively. In conclusion, the aqueous extract of Allium sativum provides a potent anti-angiogenesis effect, and its combination with melatonin had a synergistic effect, further enhancing its anti-angiogenesis effect.

Published: June 2024

In this paper, we have introduced some viscosity-type inertial iterative methods for solving fixed point and variational inclusion problems in Hilbert spaces. Our methods calculated the viscosity approximation, fixed point iteration, and inertial extrapolation jointly in the starting of every iteration. Assuming some suitable assumptions, we demonstrated the strong convergence theorems without computing the resolvent of the associated monotone operators. We used some numerical examples to illustrate the efficiency of our iterative approaches and compared them with the related work.
Boundedness and higher integrability of minimizers to a class of two-phase free boundary problems under non-standard growth conditions
Authors: Liu Jiayin , Zheng Jun
Published: June 2024

In this paper, we are concerned with the existence, boundedness, and integrability of minimizers of heterogeneous, two-phase free boundary problems $ \mathcal {J}_{\gamma}(u) = \int_{\Omega}\left(f(x, \nabla u)+\lambda_{+}(u^{+})^{\gamma}+\lambda_{-}(u^{-})^{\gamma}+gu\right)\text{d}x \rightarrow \text{min} $ under non-standard growth conditions. Included in such problems are heterogeneous jets and cavities of Prandtl-Batchelor type with $ \gamma = 0 $, chemical reaction problems with $ 0 < \gamma < 1 $, and obstacle type problems with $ \gamma = 1 $, respectively.

Published: June 2024

Accurately estimating the number of infections that actually occur in the earliest phases of an outbreak and predicting the number of new cases per day in various countries is crucial for real-time monitoring of COVID-19 transmission. Numerous studies have used mathematical models to predict the progression of infection rates in several countries following the appearance of epidemiological outbreaks. In this study, we analyze the data reported and then study several logistical-type phenomenological models and their application in practice for forecasting infection evolution. When several epidemic waves follow one another, it is important to stress that a traditional logistic model cannot necessarily be fully adapted to the data made available. New models are being introduced to simultaneously take account of human behavior, measures taken by the government, and epidemiological conditions. This research used a generalized logistic model based on parameters that vary over time to describe trends in COVID-19-infected cases in countries that have undergone several waves. In two-wave scenarios, the parameters of the model evolve dynamically over time following a logistic function, where the first and second waves are characterized by two extreme values for the early period and the late one, respectively.
Endogenous Information and Simplifying Insurance Choice
Authors: Brown Zach Y. , Jeon Jihye
Published: June 2024

In markets with complicated products, individuals may choose how much time and effort to spend understanding and comparing alternatives. Focusing on insurance choice, we find evidence consistent with individuals acquiring more information when there are larger consequences from making an uninformed choice. Building on the rational inattention literature, we develop and estimate a parsimonious demand model in which individuals choose how much to research difficult‐to‐observe characteristics. We use our estimates to evaluate policies that simplify choice. Reducing the number of plans can raise welfare through improved choice as well as savings in information costs. Capping out‐of‐pocket costs generates larger welfare gains than standard models. The empirical model can be applied to other settings to examine the regulation of complex products.
