Flow under long two-dimensional dam sluice gate using WSPH

An application of the Weakly compressible Smoothed Particle Hydrodynamics (WSPH) numerical method is presented here for the case of two-dimensional flow in a long channel with a partially open sluice gate. The results are compared with an analytical solution provided by shallow water equations (SWE) and available experimental data for instantaneous discharge depth at the gate. Of particular interest is the application of this numerical method to a sluice gate case with a high ratio of channel length to depth, which tends to amplify the effects of the chosen numerical resolution. General model congruence was within 5 % of a margin error even for relatively low vertical resolution, and some side effects of the equations used to describe the boundary conditions were identified.
Empirical Evidence of Asset Pricing Based on Single Index Model, Fama, and French Three and Five-Factor Models in Indonesia Stock Exchange

This empirical test aims to estimate the beta parameters of the risk premium and other risk factors and compare the performance of the singleindex model, Fama and Frech three and five-factor models. The sample used as the study object is companies in the property and real estate subsector with data collected from datastream Thomson Reuters from January 2014 to December 2018. The results are consistent with the previous studies that asset pricing using the Fama and French five-factor model can better explain stock returns than the other two models. The property and real estate subsector seems to provide a positive and statistically significant abnormal return, indicating that asset pricing with the three models is irrelevant to Indonesia. These results suggest that the stock market in Indonesia is still inefficient.
Do romantic relationships promote happiness? Relationships’ characteristics as predictors of subjective well-being

This study aimed to investigate the predictive power of aspects of the romantic relationship on subjective well-being, beyond what is explained by sociodemographic and personality variables. Participants were 490 heterosexual adults (68.8% women), all involved in a monogamous romantic relationship. Romantic relationship variables were substantial predictors of the three components of subjective well-being, explaining 21% of the variance in life satisfaction, 19% of the variance in positive affect, and 15% of the variance in negative affect, in addition to sociodemographic variables and personality factors. Still, relationship satisfaction was one of the main predictors of subjective well-being. The results highlight the importance of romantic relationships over subjective well-being, suggesting that cultivating satisfying romantic relationships contributes to a happier life.
Effect of vitamin D levels in benign paroxysmal positional vertigo

<p class="abstract"><strong>Background:</strong> Benign paroxysmal positional vertigo (BPPV) is a common cause of disabling vertigo with a high rate of recurrence. BPPV is the most common cause of neurotological disorder. It is caused by dislodged otoconia which fall from the utricular macula and float into the semicircular canals there by making them sensitive to gravity. It has been shown that elderly people may suffer from unrecognized, chronic BPPV. Patients with unrecognized BPPV were more likely to have reduced activity of daily living scores, to have sustained a fall in the previous 3 months and to have depression. </p><p class="abstract"><strong>Methods:</strong> A prospective study of 100 patients with clinical diagnosis of BPPV visiting Navodaya medical college and hospital between June 2019 to May 2020 were included in the study. </p><p class="abstract"><strong>Results:</strong> Patients taking both vitamin D supplementation and rehabilitation therapy improved better than patients taking rehabilitation therapy alone. </p><p class="abstract"><strong>Conclusions:</strong> Both rehabilitation therapy and supplementation of vitamin D is helpful in patients with vitamin D deficient BPPV patients. </p>
Patient Satisfaction towards Non-Surgical Periodontal Therapy

Objective: This study aimed to evaluate the patient satisfaction towards non-surgical periodontal therapy. Methods: This cross-sectional study included 102 patients (> 20 years old) who were visiting the dental hospital at King Abdul-Aziz University, Jeddah, Saudi Arabia. Patients answered the 13-item satisfaction questionnaire on periodontal therapy via electronic and manual survey. Scores were analyzed using descriptive statistics, independent t-test, and One-way ANOVA with Least Significant Difference. Results: Most of the participants had thought of professional cleaning as highly efficient, and that experienced minimal gum bleeding, pain, teeth pressure, sensitivity, absence of gagging, and minimal inconvenience brought by sounds during professional cleaning session. The overall mean satisfaction score of participants was 22.79 ± 4.4 (n = 102, min = 8, max = 30), suggesting a very good level of satisfaction experienced by them concerning non-surgical periodontal therapy. Furthermore, significantly higher mean satisfaction score was found for patients with gingivitis having bachelor’s degree of education (score = 24.67 ± 3.4; n = 36) compared to those High School graduates with gingivitis (score = 21.27 ± 44.6; n = 11). This implies a favorable treatment experience for bachelor’s graduates having gingivitis that those High School graduates with the same condition. Conclusion: Mapping the patient-based outcomes of non-surgical periodontal treatment through assessment of their satisfaction is important in evaluating the effectiveness of such therapy, which consequently helps in the enhancement of strategies, patient safety, and limitations related with non-surgical treatment of periodontal condition.
The Effects of Some Climate Factors upon Frequency Distribution of Local Sandflies Breed in Misan Province, Iraq

The genus Phlebotomus is naturally responsible for the transmission of many protozoal parasites like Leishmania. The study was conducted to determine the effect of some climate factors on sandflies distribution over a year from December 2019 to November 2020. A total of 268 sandflies of both sexes were collected from different areas in Misan province, Iraq. Sandflies were collected using light traps and stick oil paper, then placed in cups or Petri dishes containing sterile normal saline for examination. The current study showed an inverse relationship between the presence and number of sandflies with temperatures. Rainfall had a significant impact on parasite distribution, while wind speed had a potential impact on sandfly activity. The percentage of female sandflies was significantly (P<0.05) higher than that of males (54.85% for females versus 45.15% for males). In conclusion, heavy precipitation is the main climate factor that affects the frequency distribution of local breed sandflies followed by rising temperature degrees that are seen in the summer season. The climate can affect the activity, spreading, and distribution of sandflies with detected one peak of their activity in December.
Smart Cities Landscape and Urban Planning for Sustainability in Brno City

This study aimed to explore the case study of Brno city regarding smart city models. We analyzed Brno considering smart and sustainable city elements, i.e., smart mobility/public transport, smart technology, smart people, smart governance, smart economy, smart living, and smart environment based on transport, energy, and environment referred herein as the smart city and sustainability model. Therefore, we investigated a case study of Brno city in the Czech Republic. We used qualitative techniques such as case study, exploration, observation, and description. We analyzed and comprehended the trends in the various features of smart city and sustainable development of the city of Brno. The findings showed that Brno city is doing its best to maintain smart city models through its governance organs and structures. The city is also working hard to improve some of the aspects that are still lagging. The ongoing developments and the future ones are based on strategic planning for both the short term and long term such as Brno2023, Brno2030, and Brno2050. It was found that Brno has a very well-planned transport system and is integrated with other aspects such as technology, energy, such as the electricity that moves the trolleybuses and trams, and environment. We strongly conclude that even though Brno city still struggles to achieve total sustainability, it is still a model and reflection of a smart and sustainable city. Finally, we noted that Brno city has very good plans and vision the “DNA” of a smart city. However, the implementation still suffers political willingness.
Characterization and profiling of polyphenolics of Brassica microgreens by LC-HRMS/MS and the effect under LED light

An untargeted approach to profiling of polyphenolics of Brassicaceae microgreens was employed to characterize the phenolic composition in microgreens grown under 8 different treatments of combined amber (590 nm), blue (455 nm), and red (655 nm) LED, using full MS and HRMS/MS-ESI. Hydroxycinnamic acid (HCA) derivatives predominated the pool of phenolics in the microgreens, followed by free phenolic acids and flavonol glycosides/ acylglycosides, with most of the HCA derivatives existing as malate esters. Most HCA malates in mustard (Barbarossa) and all HCA malates in mizuna (red kingdom)/ radish (red Rambo, organic) were significantly decreased under most treatments, whereas all malates were overall increased under combined lighting in radish (red Rambo), mustard (Garnet Giant), mizuna (organic), Pac choi (red Pac) and mustard (Scarlet Frills). The present study demonstrated that amber in combination with blue and red LED contributed to the altered phenolic profile and increase and/or decrease in quantity of certain phenolic compounds, particularly the HCA malates.
Colistin Sensitivity and Factor H-Binding Protein Expression among Commensal <italic toggle='yes'>Neisseria</italic> Species

Many bacterial carriage studies utilize colistin-containing media to select for Neisseria meningitidis among the diverse human pharyngeal milieu. These studies commonly report the isolation of Neisseria commensal species, with carriage rates of around 1% or less typically observed. Here, we describe the isolation of N. cinerea and N. polysaccharea from pharyngeal swabs using nonselective agar and confirm they are unable to grow on colistin-containing media. We also demonstrated colistin sensitivity among archived Neisseria commensal strains, including N. cinerea, N. polysaccharea, N. mucosa, and N. subflava. The distribution of lptA among these strains indicated that, while the phosphoethanolamine (PEA) transferase encoded by this gene confers colistin resistance, other mechanisms may lead to reduced susceptibility in some lptA-deficient strains. The majority of the N. cinerea and N. polysaccharea isolates expressed medium to very high levels of factor H-binding protein (fHbp), an important meningococcal vaccine antigen. Sequence analysis showed that the commensal fHbp peptide variants were similar in sequence to fHbp variants typically observed among invasive meningococci. Altogether, these results not only suggest that Neisseria commensal strains could be carried at much higher rates than previously reported but also raise questions about the impact of protein-based meningococcal vaccines on these unencapsulated commensals. IMPORTANCE This study highlights the need for further work to accurately determine the pharyngeal carriage prevalence of Neisseria commensal bacteria (e.g., N. cinerea and N. polysaccharea) among the general population. Previous studies have clearly demonstrated the suppressive effect these commensal species can have on meningococcal colonization, and so the carriage prevalence of these species could be an important factor in the spread of meningococci through the population. Furthermore, the surface expression of the meningococcal vaccine antigen factor H-binding protein by many of these commensal strains could have important implications for the use of fHbp-containing vaccines. Carriage of these commensal species may influence the immune response to these vaccines, or conversely, the immune response elicited by vaccination may induce clearance of these potentially important members of the pharyngeal niche.
Effect of Temperature on Gas and Liquid Products Distribution in Thermal Cracking of Nigerian Bitumen

The increasing population growth resulting in the tremendous increase in consumption of fuels, energy, and petrochemical products and coupled with the depletion in conventional crude oil reserves and production make it imperative for Nigeria to explore her bitumen reserves so as to meet her energy and petrochemicals needs. Samples of Agbabu bitumen were subjected to thermal cracking in a tubular steel reactor operated at 10 bar pressure to investigate the effect of temperature on the cracking reaction. The gas produced was analyzed in a Gas Chromatograph while the liquid products were subjected to Gas Chromatography-Mass Spectrometry (GC-MS) analysis. Heptane was the dominant gas produced in bitumen cracking at all temperatures and the reaction products show a distribution of lighter hydrocarbons most of which are in the gasoline range. The product distribution of bitumen conversion depends strongly on the cracking temperature and the oil produced contains the valuable liquid fractions. The products of thermal cracking of bitumen can be classified into the following groups; alkanes, alkenes, amines, aromatics, alkanoic acids, alkanols, esters, ethers, ketones, sulphur compounds, and nitrogen compounds. The activation energies of the products formed were determined. The LNG produced all have unusually low values activation energy (hence easily converted) pointing to the high quality of Agbabu crude The conversion process was affected by the reaction time and suggests that the transformation of bitumen into smaller fractions follows a definite reaction scheme in which the heavy oil transformed to lower fractions and was subsequently converted to smaller liquid fractions and gases.
Early versus late third trimester maternal SARS-CoV-2 BNT162b2 mRNA immunization maximizes transplacental antibody transfer and neonatal neutralizing antibody levels

Objective We aimed to assess the impact of early versus late third trimester maternal SARS-CoV-2 vaccination on transplacental transfer and neonatal levels of SARS-CoV-2 antibodies. Methods Maternal and cord blood sera were collected following term delivery after antenatal SARS-CoV-2 BNT162b2 mRNA vaccination, with the first vaccine dose administered during 27-36 weeks gestation. SARS-CoV-2 spike protein (S) and receptor binding domain (RBD)-specific, IgG levels and neutralizing potency were evaluated in maternal and cord blood samples. Results The study cohort consisted of 171 parturients (median age, 31 years; median gestational age, 39.7 weeks): 83 (48.5%) immunized at early 3rd trimester (1st dose at 27-31 weeks), and 88 (51.5%) immunized at late 3rd trimester (1st dose at 32-36 weeks). All mother-infant paired sera were positive for anti S- and anti-RBD-specific IgG. Anti-RBD-specific IgG concentrations in neonatal sera were higher following early versus late 3rd trimester vaccination and were positively correlated with increasing time since vaccination (r= 0.26; P=0.001). The median placental transfer ratios of anti-S and anti-RBD specific IgG were increased following early versus late 3rd trimester immunization (anti-S ratio:1.3 vs. 0.9, anti-RBD-specific ratio:2.3 vs. 0.7, P<0.001). Neutralizing antibodies placental transfer ratio was greater following early versus late 3rd trimester immunization (1.9 vs. 0.8, P<0.001), and was positively associated with longer duration from vaccination (r= 0.77; P<0.001). Conclusions Early- as compared to late third trimester maternal SARS-CoV-2 immunization enhanced transplacental antibody transfer and increased neonatal neutralizing antibody levels. Our findings highlight that vaccination of pregnant women early in the third trimester may optimize neonatal seroprotection.
Prevalence of maxillary canine impaction in an Egyptian population: a retrospective study

Objective: To determine the prevalence of maxillary impacted canines in Egyptian population and its relativity to gender, location, and side distribution. Materials and methods: Retrospective cross-sectional study of 7730 digital panoramic radiographs collected from Alexandria city in Egypt. The sample was examined for the presence of maxillary impacted canines. The radiographs were selected from the records of several private dental clinics and the archive of a radiographic center. Results: Among the panoramic radiographs analyzed, 229 radiographs had at least one maxillary canine impaction with a prevalence of 2.96%. The percentage of impacted canines in males was 36.24% and in females was 63.76%. A higher number of impactions were seen unilaterally 82.1% than bilaterally 17.9%. Right side impactions (42.79%) were less common than left side impactions (75.1%) in relation to the total number of radiographs with canine impactions. When including the unilateral impactions only, right side impactions were 24.89% while the left side impactions were 57.2%. Conclusions: The prevalence of maxillary impacted canines in the Egyptian population was found to be 2.96% of the sample collected from Alexandria city which lies within the range reported in other populations. The maxillary canine impactions occurred more in females, unilaterally and on the left side.
Comparison of methodologies for determining the thermal performance of houses with a concrete wall-type structural system

The thermal performance of a building is an important factor in homes when it is concerned with offering the user the thermal comfort that the user is entitled to have. A building must be designed for the climate in which it is inserted in order to have a greater potential in providing thermal comfort, and still save energy. This work aimed to evaluate the thermal performance, according to the guidelines of the Brazilian Performance Standard NBR 15575 of a singlefamily building located in the city of Águas Belas-PE, Brazil. The evaluation of thermal performance was performed through two procedures present in NBR 15575: the simplified procedure and the computational simulation. As a methodology, an exploratory research and a case study were carried out. The evaluation through the simplified method was given by calculations of thermal transmittance and thermal capacity of the building envelope, that is, of the facade walls and roof. The computational simulation was performed using the EnergyPlus program, which with climatic information and a three-dimensional model of the building was able to test the climatic conditions on the building and determine its thermal behavior. The results obtained through the analysis by the two procedures previously mentioned were compared and analyzed according to the requirements of NBR 15575, were small divergences between them was noted. Computer simulation proved to be more effective when compared to the simplified procedure.
Estimating the Birefringence and Absorption Losses of Hydrogen-bonded Liquid Crystals with Alkoxy Chains at 2.5 THz

SUMMARY Liquid crystal (LC) device has high tunability with low power consumption and it is important not only in visible region but also in terahertz region. In this study, birefringence and absorption losses of hydrogen-bonded LC was estimated at 2.5 THz. Our results indicate that introduction of alkoxy chain to hydrogen-bonded LC is e ﬀ ective to increase birefringence in terahertz region. These results indicate that hydrogen-bonded LCs are a strong candidate for future terahertz devices because of their excellent properties in the terahertz region.
A Mother with A Tumour Close To Her Heart: A Case Report on the Management of a Thymoma in Pregnancy

10.30699/jogcr.6. 3.157 Thymomas are seldom encountered in the general population, and even more-so uncommonly encountered in pregnancy. Patients usually present with either local, compressive symptoms such as shortness of breath or are asymptomatic and diagnosed incidentally on imaging studies. A subset of them may even present in association with myasthenia gravis. Management of pregnant patients with thymomas are challenging and require multi-disciplinary care involving thoracic surgeons, maternal-fetal medicine specialists, neonatologists and anaesthesiologists to facilitate safe progression of the pregnancy. We discuss the management of a patient that presented to us with a B2-type thymoma in pregnancy who successfully underwent a video-assisted thoracoscopic excision of the mass and went on to have a safe delivery. The optimal way forward in managing patients with thymomas in pregnancy would be through early recognition of the condition and instituting a mutlidisciplinary approach.
Comparison of weight-adjusted dose versus fixed dose ondansetron in Prevention of shivering following spinal anaesthesia for caesarean deliveries

Background: Spinal anaesthesia is a reasonable alternative of regional anaesthetic that is indicated for around 86 % of caesarean sections performed in the United States and the United Kingdom. Neuroaxial block is used in approximately 80% of caesarean sections performed at Al-Azhar University hospitals. Shivering is a common symptom of spinal anaesthesia, affecting 40 to 64 % of individuals. Shivering could be uncomfortable for the mother and impair anesthesiologists' monitoring of the patient during caesarean procedures. Where ondansetron is a 5-HT3 receptor antagonist that can be used to treat and prevent shivering after spinal anaesthesia. According to the studies, administering a fixed dose in individuals of varying weight obscured ondansetron's dose effect on avoiding shivering, resulting in a higher frequency of shivering when the dose was not weight-balanced. Aim of the work: To compare weight-adjusted ondansetron to a fixed dose of ondansetron and pethidine as a control treatment for shivering regression during spinal anaesthesia for caesarean deliveries. Patients and Methods: A prospective, randomised, double-blind, controlled clinical trial with 129 patients scheduled for elective caesarean surgery was carried out. Three similar groups of women were assigned at random. Following spinal anaesthesia, the first group (FDO) received a fixed dosage of ondansetron (4mg), the second group (WAO) received a weight-adjusted dose of 0.1mg/kg ondansetron, and the control group (PC) received 0.5 mg/kg pethidine. During surgery and the postoperative period, the frequency and severity of shivering were noted, as well as the occurrence of headache, pruritus, nausea, and vomiting. Results: Shivering was seen in 13 patients (30.2 % ) in the first group (FDO), 11 patients (25.6 % ) in the second group (WAO), and 11 patients (25.6 % ) in the third group (PC), but there was no significant difference between groups ,The first group (FDO) 5 patients (11.6 %) shivered severly more than the second group (WAO) 3patients (7.0 %). Conclusion: A weight-adjusted dose of 0.1 mg/kg significantly reduced the frequency and intensity of post-spinal shivering while also lowering adverse effects and enhancing hemodynamic stability.
