Published: April 2023

AbstractBackgroundVarious recent studies have investigated the use of traditional fibers (metallic or synthetic) as reinforcement in mortar. In recent times, there has been growing interest in using natural fibers as reinforcement in cement composites. This study was conducted to assess the impact of date palm, doum palm, and sisal fibers on the mechanical properties of cement composites. Genetic modeling was chosen to find the shear damage at the fiber-matrix interface of the three cement composites using genetic crossing operator, which allows us to calculate the damage at the interface using two damages of the matrix and the fibers, respectively.ResultsOur objective is to examine and evaluate the interface damage of date palm/mortar, doum palm/mortar and sisal/mortar under different mechanical tensile stresses ranging from 25 to 37 MPa with fiber volume fraction from 1 to 5%. It was found that the interface damage of date palm/mortar and doum palm/mortar cement composites was minimal compared to that of sisal/mortar. However, several researchers found that an increase in fiber volume fraction leads to decrease in mechanical properties and density in cement composites what we confirmed in this study that interface damage increases when the volume fraction increases.ConclusionsThe results are in line with the findings of a recent experimental study on the use of other plant fibers. Their results showed that incorporating ramie fibers resulted in a 27% increase in compressive strength, whereas the use of synthetic fibers resulted in 4% decrease in tensile strength in compression. It is recommended the use of doum and date palm natural fibers in the composition of mortars with a fiber volume fraction of 1 to 5% in order to reduce and avoid interface damage and limit the negative impact of synthetic fibers on the environment.

Background/AimsPregnant women are at higher risk for severe illness from COVID-19 than non-pregnant women. Research investigating risk factors and clinical manifestations of COVID-19 in pregnant women is limited in Indonesia. Therefore, this study's aim was to investigate these clinical issues.MethodsFor this observational cross-sectional study, data were collected from Merah Putih Government Hospital. A total of 106 medical records were analysed using descriptive statistics and Pearson's Chi-squared test, to examine differences in risk factors or clinical manifestations in pregnant women with or without COVID-19.ResultsThere were no significant differences between the two groups in terms of risk factors such as diabetes, bronchial asthma and cardiovascular disease. There were significant differences between the groups for clinical manifestations of fever, cough, dyspnea, ageusia, rapid antigen test and lymphocytopenia.ConclusionsCoordinated care strategies should be initiated, particularly in the assessment of vulnerable pregnant women. Future pandemic preparedness studies should be considered to improve and protect maternal and child health in Indonesia.

Abstract
Turbine inlet air temperatures are extremely high, which can result in blade material damage. As a result, cooling the turbine blades is required, and a variety of cooling techniques have been introduced. The majority of the previous research on pin fins has focused on circular fins using a wedge duct to apply a constant temperature and uniform heat flux to the end wall and pin fin surfaces. The present study compares seven oblong pin-fins to seven circular pin fins in a wedge duct with a Reynolds number range of 10,000–50,000 and a constant heat flux (surface) of 3280 W/m2 applied to the endwall and surfaces of the oblong pin fin. The results indicate that the friction factor for oblong fins is 14% lower than for circular pin fins. The thermal performance factor is increased by 11.4%. The thermal performance factor can be improved by using oblong pin fins with higher Reynolds numbers.

: Urticaria is the most common skin disorder in children presenting to the paediatric department. Sometimes it can also present with angioedema which is an emergency condition requiring immediate treatment. Hence this study signifies the importance of Absolute eosinophil count and serum IgE in childhood urticaria and its correlation with disease severity and management.To analyse the Absolute eosinophil count and serum IgE in children with urticaria from age group of 1-12 years and its correlation with disease severity. An observational study on 49 children with urticaria and measurement of Absolute eosinophil count and serum IgE and categorised based on urticaria activity score.Most common age group affected was 5-12 years and mean age was 6.75±3.47. Out of 49 children, 97.95% of the affected children have raised serum IgE levels, 39% of the affected children have raised Absolute Eosinophil Count. There was also increase in serum IgE levels with increase in AEC levels were found.The disease severity increases with increasing levels of absolute eosinophil count and serum IgE in children with urticaria. Hence this study suggests that absolute eosinophil count and serum IgE should be regareded as a valuable markers in childhood urticaria.

Abstract

Background: Sleep apnea is usually associated with negative outcomes and underdiagnoses. STOP-Bang Questionnaire is a screening method for obstructive sleep apnea (OSA) that is recognized for the diagnosis of OSA in surgical and medical patients. This cross-sectional study aimed to evaluate the ability of the STOP-Bang test to predict complications after supratentorial craniotomy.
Methods: In a cross-sectional study, 200 patients who were candidates for supratentorial craniotomy surgery who were referred to Loghman Hospital from July 2019 to September 2020 were included in the study. The STOP-Bang questionnaire was completed the day before the operation or during the visit to the anesthesia clinic. Demographic characteristics, body mass index (BMI), neck and waist size, underlying disease, and airway examination were performed to assess the Mallampati score for patients. According to the STOP-Bang scoring system, patients were categorized into two groups: low risk (score less than 3) and high risk (score higher or equal to 3). Data were analyzed using SPSS software version 20.
Results: A total of 125 patients (62.5%) were low risk and 75 patients (37.5%) were high-risk. There was no statistically significant difference between the two groups of patients in terms of gender (P = 0.108). BMI over 35 kg / m2 and age over 50 years were higher in the high-risk group. The incidence of Malampati III or IV was higher in the high-risk group (29.3 vs. 6.4%). Smoking was higher in the high-risk group (29.3 vs. 16.8%). The frequency of airway obstruction, re-intubation, hypoxia, and length of hospitalization in recovery, and in the intensive care unit was significantly higher in the high-risk group. The level of the ROC curve for airway obstruction required intervention equal to 70.2% (95% confidence interval: 79.6-6.7). STOP-Bang showed good predictive power (Diagnostic power> 50percentage) for the need for nasal or oral airway implantation, re-intubation, hypoxia and hypotension of arterial blood, and difficulty in breathing or speaking. A score higher than two showed the predictive power of all evaluated outcomes.
Conclusion: Our findings showed that the occurrence of premature respiratory complications after supratentorial craniotomy surgery is more common in patients with a screening score of three or higher on the STOP-Bang test, and this test can detect adverse complications after surgery.

Abstract
Polycystic ovary syndrome (PCOS) is the leading cause of anovulatory infertility. Herein, we aimed to screen GDF9 of mature follicles in women with differentPCOS phenotypesundergoing controlled ovarian hyperstimulation (COS) and analyse the correlation between GDF9 expression levels and the oocyte developmental ability. In this study, we compared the level of GDF9 in follicular fluid (FF) and cumulus cells(CCs) of mature follicles collecting from different PCOS phenotypes. The indenpendent effect of GDF9 on blastocyst formation and clinical pregnancy was determined by Binary Logistic Regression analysis. The GDF9 levels in FF for phenotype A and B were significantly increased, compared to the phenotype D, (P=0.019, P=0.0015, respectively). Increased GDF9 expression in CCs of phenotype A and B was accompanied by the changes of FF. The analysis of the multivariable logistic regression showed that GDF9 was a significant independent prognosticator of blastocyst formation(P＜0.001). The phenotype A had a higher percent of blastocyst formation than the phenotype B and D (P＜0.001). Taken together, GDF9 expression varied in different PCOS phenotypes. The phenotype A had a higher GDF9 level and even more ability of blastocyst formation.

Published: April 2023

Abstract
At present, human translation is characterized by low efficiency, high cost, high consumption of resources and time, so it is urgent to study automatic translation technology to meet the needs of information interaction and language communication in various countries under the background of economic globalization. This topic has also become a hot issue in the field of translation. After a long period of development, machine translation technology has gradually become popular and widely used, replacing human translation technology as the mainstream technology. Therefore, this paper implements the construction of an interactive system of English Chinese bilingual translation model based on cloud computing environment by introducing deep learning algorithm. The system can learn by itself on the basis of analyzing source documents, and predict target translation output by extracting features. The system is equipped with a translation engine based on the data source, which can realize interactive translation, and the final output can be achieved by processing the predicted translation output and based on the translator's understanding. Through the design of simulation experiments for system detection, the results show that the Chinese English translation model system has a high translation quality. By comparing it with the baseline system, it can be seen that both of them can translate sentences normally in 8 PR cycles (PR * 8, about 18% KSMR), and the data set improvement rate is about + 35 BLEU, that is, 76 BLEU is finally achieved. This proves that users can maintain the translation accuracy while reducing the number of effective interactions by using the optimized translation model to translate the target text, showing the effectiveness. In this paper, an interactive Chinese English translation system is designed by combining deep learning with cloud computing.

Published: April 2023

AbstractBackground:As the number of studies investigating idiopathic pulmonary fibrosis (IPF) and lung adenocarcinoma (LUAD) continues to grow, increasing evidence supports a strong correlation between these two diseases. However, the underlying common pathophysiological mechanisms remain unclear.Objective：The objective of this study is to further elucidate potential key genes and pathological mechanisms associated with IPF and LUAD.Methods:We searched and downloaded the gene expression datasets for IPF patients and their corresponding normal tissue (GSE53845), as well as the datasets for LUAD patients and normal tissue (GSE176348) from the Gene Expression Omnibus (GEO) database. Using these datasets, we identified differentially expressed genes (DEGs) and common genes, which were subjected to gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analyses. To further elucidate the underlying mechanisms of IPF and LUAD, we constructed a protein-protein interaction (PPI) network and identified transcription factors (TFs) that may regulate key genes.Results:Ninety-three common genes were identified in both the IPF and LUAD datasets with a significance level of P<0.05. Enrichment analysis revealed 936 GO terms and 13 KEGG pathways. Using cytoHubba and van plots, we selected the top thirteen key genes, including COL1A1, COL3A1, TIMP3, IGF1, CTHRC1, SULF1, MMP12, WNT3A, CCL5, GREM1, CCL19, HPGD, and AKR1C3, and further analysis of these genes was performed. GO analysis revealed significant enrichment in the regulation of animal organ morphogenesis, extracellular matrix organization, and extracellular structural organization. The KEGG pathway enrichment analysis showed that proteoglycans were significantly enriched in cancer, ovarian steroidogenesis, and arachidonic acid metabolism. Furthermore, we identified six TFs that may regulate the expression of these key genes.Conclusions:Our findings suggest that specific key genes and shared mechanisms play a role in the development and progression of both IPF and LUAD. These key genes and mechanisms may represent potential targets for therapeutic intervention and provide novel insights into the underlying pathophysiology of these diseases.
Electrodynamics-based Quantum Gate Optimization with Born Scattering
Authors: Gautam Kumar 
Published: April 2023

Abstract
In this paper, we propose employing electron scattering to realize unitary quantum gates that are controlled by three qubits. Using Feynman’s rules, we find an expression for the transition amplitude for scattering from an external electromagnetic source. In this context, the scattering amplitude is modeled as a unitary gate whose state can be regulated. The optimal value of the vector potential needed to implement the gate is obtained by minimizing the difference between the designed gate and the target gate, with the total energy consumed as a constraint. The design algorithm is obtained by discretizing the resulting integral equations into vector equations. This design algorithm can be applied in various fields such as quantum computing, communication, and sensing. It offers a promising approach for developing efficient and accurate gates for quantum information processing. Furthermore, this approach can also be extended to design gates for multi-qubit systems, which are essential for large-scale quantum computing. The use of this algorithm can significantly contribute to the development of practical quantum technologies.

Abstract
INTRODUCTION
Activated coagulation time (ACT) measurement is performed to monitor the level of anticoagulation provided by heparin during cardiopulmonary bypass, coronary angioplasty and dialysis. In this study, the newly developed device and the consumable ACT tubes of this device were compared with the current methods used in hospitals and its usability as a reliable product was evaluated.
METHOD
This study was carried out in the cardiovascular surgery operating room of Gazi University Medical Faculty Hospital after the approval of the ethics committee and the approval of the Turkish Medicines and Medical Devices Agency . A total of 100 patients over the age of 18 who received heparin during cardiac surgery were included in the study. In our routine practice, Hemochron device with cuvettes (Hemochron Signature, Spain) constituted the “Hemochron cuvette” group and Hemochron device with tubes (Hemochron Response, Spain) constituted the “Hemochron tube” group. Hemonart device and tubes (CompactOne 9 and BlacT-ACT tube) constituted the “Hemonart tube” group. Measurements made with the above 3 devices simultaneously; the baseline value before heparinization was repeated at 5th minute after heparinization, after the initiation of cardiopulmonary bypass, and 5 minutes after protamine administration. The correlation of the measurements obtained with the 3 devices was evaluated.
RESULTS
When basal ACT measurements were evaluated; The mean ACT of Hemonart tube was measured as 148.54±26.54 sec and Hemochron tube (122.67±16.38) and Hemochron cuvette (117.94±15.06) values were statistically significantly higher (p<0.0001, p<0.0001, respectively). When measurements after heparin and during cardiopulmonary bypass were evaluated; Hemonart tube and Hemochron tube mean ACT values were similar in both groups (p=0.356) but statistically higher than Hemochron cuvette values (p<0.0001, p=0.003, respectively). Mean ACT values of Hemonart tube following protamine administration were statistically significantly higher than Hemochron tube and Hemochron cuvette values (p<0.0001, p<0.0001, respectively). A positive correlation was found between the values measured with different devices at all measurement time points. The strongest correlation was found between Hemonart tube and Hemochron tube values at baseline, post-heparin, during cardiopulmonary bypass and following protamin administration (r=0.546, p<0.0001; r=0.512, p<0.0001; r=0.533, p<0.0001, r= 0.407, p=0.001, respectively).
CONCLUSION
It has been concluded that Hemonart brand devices and tubes can be used safely.

Однією з важливих проблем сьогодення була пандемія Covid-19, яка сколихнула життя людей, зокрема вплинула і на навчання сту-дентів. У результаті чого студентів вишів з початком пандемії перевели на дистанційне навчання. Актуальною для нас стала проблема вивчення психо-емоційного стану студентів в умовах дистанційного навчання, соматичних і поведінкових проявів їхньої тривожності.
Метою статті є оцінити психоемоційний стан, соматичні та по- ведінкові прояви тривожності у студентів-медиків впродовж дистан- ційного навчання.
Методи дослідження. Опитано 76 студентів 2 курсу шляхом анонім- ного анкетування. Для обстеження було використано онлайн-анкету на базі Google Forms, яка включала запитання з метою вияв-лення психоемо- ційних та соматичних проявів тривожності. Для досяг-нення поставленої мети були поставлені наступні завдання: виявити емоційно-поведінкові реакції студентів та дослідити соматичні прояви тривожності за допо- могою розроблених опитувальників.
На основі аналізу результатів анкетування виявле-но, що всесвітня пандемія Covid-19 була значним соціальним фактором, який впливав на функціонування організму та поведінкові реакції сту-дентів, але більшість із них навчилися контролювати свої емоції та поведінку. Тільки 19,7% ре- спондентів повідомили про збільшення нега-тивних емоцій у повсякден- ному житті під час дистанційного навчан-ня, тоді як 40,8% повідомили про зниження інтересу до дистанційного навчання порівняно з навчанням

офлайн, відмічали часте відчуття тривоги та апатію. Впродовж дис- танційного навчання психоемоцій-ний стан погіршився у близько 25% респондентів.
Вивчивши прояви тривожності на соматичному рівні, ми вияви-ли, що більшість студентів не мали ознак соматичних проявів триво-жності, 63,2% студентів ніколи не відчували запаморочення чи головного болю впродовж дистанційного навчання, 75% студентів ніколи не відчували тремору. Фактично, 71,1% з них не відмічали підвищення ча-стоти серцевих скорочень або підвищеного артеріального тиску впро-довж дистанційного навчання, але більшість респондентів (56,6%) часто відчували втому або сонливість.
Наші дослідження показали, що світова пандемія мала негативний вплив на функціонування організму та поведінкові реакції студентів. Проте за період дистанційного навчання студенти вироби-ли стресостійкість і навчилися адекватно реагувати на соціальні виклики, які постають перед людством, починаючи з 2019 року.

Published: April 2023

Soil transmitted helminth infections (STHI) are prevalent among elementary school children in Indonesia. The nutritional impairments that an infection can cause have their consequences for the children’s development and health. This study aimed to determine children’s knowledge and behaviour in relation to the prevalence of STHI among elementary school children in Jepara, a rural regency in Indonesia. The study intended to evaluate the effectiveness of the current elimination program for STHI in this area. A cross-sectional study was conducted among 132 children from eight elementary schools in Mlonggo, Jepara. The research population consisted of children aged eight to ten years old. During September and October 2018, the research population was obtained by consecutive sampling. Information about the children’s knowledge and behaviour regarding STHI was collected using a questionnaire. Stool samples were collected to determine STHI prevalence. Analysis was done using chi-squared and Spearman’s rho tests. Out of 132 children examined, no children had STHI. Scores on STHI knowledge were most often low (51.5%), while scores on behaviour were mostly average (67.4%). Statistical analysis showed that residence was significantly associated with the level of knowledge about STHI (P = 0.007). Additionally, gender (P = 0.002) and a previous STHI (P = 0.041) were significantly associated with the children’s behaviour concerning STHI. This study revealed inadequate knowledge and behaviour concerning STHI in elementary school children in Mlonggo, Jepara. Even though the prevalence of STHI was 0% in the study population, a proper health education program to teach children about STHI is still necessary.
