Dominant jerks: People infer dominance from the utterance of challenging and offensive statements
Authors: De Araujo Emma , Altay Sacha , Bor Alexander , Mercier Hugo
Published: March 2022

Could there be upsides to rudely challenging people’s positions? If no one calls out the speaker of a challenging or offensive statement, it might be because the audience is afraid to challenge the speaker, thereby suggesting the speaker holds a dominant position. In two experiments (N = 635), participants read vignettes in which a speaker uttered a statement that was challenging (it directly clashed with the audience’s prior views) or unchallenging (it agreed with the audience’s prior views). We also manipulated whether the audience accepted or rejected the statement after it was uttered. In Experiment 1 the statements were about mundane topics, while in Experiment 2 the statements were offensive. In both experiments, speakers uttering challenging statements that the audience nonetheless accepted were deemed more dominant and more likely to be the boss of the audience members. This shows that people use audience reactions to challenging statements to infer dominance, and suggests that people might use the utterance of challenging statements to demonstrate their dominance.

Authors: Peng Yue , Liu Qiang , Zhang Kai , Xu Yajing , Feng Xiaojuan
Published: March 2022

Thermophysical properties of working fluids are the basis for thermodynamic cycle design and optimization. The speed of sound is an important thermodynamic property that can be accurately measured. An apparatus, based on the pulse-echo technique, was developed to measure the speed of sound in compressed fluid for temperatures from 313 K to 453 K with pressures up to 100 MPa. A heat pipe thermostat was designed to provide a stable and uniform temperature field for the speed of sound measurement. The temperature field in the thermostat was simulated by COMSOL Multiphysics software. The temperature stability and uniformity of the sample in the pressure vessel were estimated to be less than 3 mK and the overall uncertainty in the temperature measurement was estimated to be within 5 mK.

Published: March 2022

The heat treatment process of C919 aircraft landing gear has to go through a series of strict environments such as vacuum, high temperature, oil quenching, and it has been a difficult problem to accurately measure the temperature of landing gear during heat treatment. A black box hi-temp measurement system is designed on basis of heat transfer theory in this paper. The thermal insulation structures are simulated by finite element analysis software ANSYS, and the simulation results indicate that the system can work continuously for 7 hours at 900 °C. The number and distribution of temperature measurement points are determined according to the standard of AMS 2750E. The temperature variations of measurement points in the process of vacuum furnace heating and oil quenching are real-time recorded by binding the hi-temp measurement system and the landing gear as a whole into the vacuum furnace and oil pool. The results show that the designed hi-temp measurement system has good stability and high accuracy, which is fully capable of withstanding vacuum, high temperature and oil quenching environments. It is the first time in China that this kind of temperature measuring problem has been solved, which is of great significance for the accurate verification of C919 aircraft landing gear during heat treatment process.

Published: March 2022

The contact angle of droplets attracts attention as one of the relevant thermophysical properties describing the wettability behaviour of the fluids. The contact angle depends on the surface characteristics such as surface type and roughness as well as on the liquid type and surrounding atmosphere. This study aims to correct the error in the coefficient of the theoretical model developed for droplet shape prediction by Vafaei and Podowski [1]. The corrected model is also rearranged by non-dimensional numbers. The contact angle and the shape of water droplets for different volumes and surface types are predicted by the rearranged model and validated by experimental results. Contact angles have been over-estimated compared to experimental results because of measurement errors in geometrical parameters. It is found that the contact angle model is too sensitive to geometrical parameters. Moreover, the contact angle is found to be independent of the volume.

Authors: Altay L. , Tantug G. S. , Cekin H. , Seki Y. , Sarikanat M.
Published: March 2022

Thermoplastics when they become thermally conductive, have a great potential to be used in thermal management applications due to their low cost, lightweight, and flexibility. Here, synthetic graphite and graphene are used as thermally conductive fillers to fabricate Polyphenylene Sulfide- (PPS) based composite materials with high thermal conductivity. Graphene and graphite added PPS composites were manufactured by using a twinscrew extruder and injection molding machine. Physical, thermal, mechanical, and morphological properties of the composites were investigated by several characterization methods including thermogravimetric analysis, differential scanning calorimetry, thermomechanical analysis, scanning electron microscopy, thermal diffusivity measurement, and tensile and flexural tests, The in-plane and through-plane thermal conductivity coefficient of graphene (5 wt. %) loaded synthetic graphite (40 wt. %)/PPS composites are greatly improved to 26.45 and 5.02 W/mK, respectively compared to that of neat PPS. The outstanding in-plane thermal conductivity of graphene loaded graphite/PPS composites is attributed to the formation of an effective thermal conductive pathway due to the alignment of the layered structure of graphene and graphite fillers in the flow direction.
Development of a new method to measure surface tension of molten oxides
Authors: Kondo Toshiki , Muta Hiroaki , Ohishi Yuji
Published: March 2022

Physical properties of molten oxides such as viscosity and surface tension are important in various fields. However, it is very difficult to measure the properties of molten oxides owing to their high melting points, high reactivity, and high vapor pressure. Hence, the physical properties of molten oxides are scarcely reported. Therefore, we developed a new method, termed the �impingement method,� for measuring the surface tension of molten oxides in a very short time, using the aerodynamic levitation technique. In this work, we developed an apparatus for measuring the surface tension of molten Al2O3 and compared the value with that of other methods, considered as reference values. Results showed that the surface tension of molten Al2O3 was approximately 0.72 N/m at around 2500 K, which is close to the reference value; moreover, the measurements could be obtained in a very short time (approximately 80 ms). Thus, it is expected that the surface tension of molten materials with high vapor pressures such as ZrO2 and UO2 can be measured using this method.
Energy bandgap variation in semiconductor compound nanomaterials
Authors: Chaturvedi Pooja , Goyal Monika
Published: March 2022

In the present work, we have used phenomological models for analyzing the impact of shape and size on energy band gap in semiconducting nanomaterial compounds. The models used presently are Qi model, Bond energy model and Guisbiers model. The extension of melting temperature expression for nanomaterials of the models considered is done and shape and size dependent expression of energy band gap is obtained. In this paper, we have taken group III-V semiconductor compound nanomaterials i.e., AlN, GaN, InN, GaAs and InAs. It is clear from the results obtained that decrease in the size of the semiconductor compound nanomaterials led to band gap expansion and this increase is significant for particle size below 5 nm. Comparison of the results predicted using different models with the available experimental and simulated results is done. Guisbiers model is found best out of the models considered to study the band gap expansion in semiconducting nanomaterial compounds. The energy band gap shift in valence and conduction band with size is determined in nanosemiconductors.

Sustainability and security of public budget of the Visegrad Group countries
Authors: Buriachenko Andrii , Zakhozhay Kostyantyn , Liezina Anastasiia , Lysak Volodymyr
Published: March 2022

The article examines the theoretical principles of studying sustainability and security of public budget of the Visegrad Group countries and determines that indicators of the normal functioning of the economy and ensuring a decent social standard of living of the population are reaching the limits of relevant indicators, some of which are approved by international standards. At the same time, the authors identified the absence of a single system of macrofinancial indicators of sustainability and security of public budget proposing to create it, including twelve ratios reflecting levels of debt security, deficit load on the economy, debt load on the population, budgetary independence, efficiency, population well-being, productivity, economic efficiency, as well as the effectiveness of financial support for health and education, elasticity of income and expenditure from the change in GDP of the Visegrad countries.

Analytical calculations of the above-mentioned macro indicators in the dynamics made it possible to draw qualitative conclusions on compliance with the sustainability and security of public budget of the Visegrad Group countries, identify possible threats to national economies and prevent the consequences in case of non-compliance with standards. Based on the results of correlation-regression analysis, the authors determined the indicators that have the greatest impact on the resultant factor-the ratio of the level of deficit load on the economy of the investigated countries. It made it possible to analyze the real situation in the economy, to determine the level of sustainability and security of public budget and to give the necessary suggestions and recommendations.
Challenges in Translating Arabic Culture-Bound Words into English: The Case of Selected Plays of the Egyptian Playwright Noaman Ashour
Authors: Gomaa Yasser , Nour El Din Amr
Published: March 2022

This study attempts to demonstrate the mediating role the translator is entrusted with and the efforts undertaken by him/her to transcend cultural barriers. Two plays written by the renowned Egyptian dramatist Noamaan Ashour feature high on this study because they are heavily laden with culture-bound expressions that mirror the Egyptian cultural milieu. Also, the study explores the strategies formulated by the translator to address the problem of culture-bound items. These items pose a challenge to the translator since they are so deeply embedded in the source culture that the translator may find it difficult to render them into the Target Language (TL). Each translation strategy has its merits and demerits: cultural substitution is a reasonable strategy, but it entails that the translator should carefully consider equivalents and the hierarchy of correspondences so as to adapt the values of the Source Language (SL) cultural system to the values of the TL cultural system. Translation by paraphrase is another viable strategy, but it is sometimes cumbersome for the translator to break up a lexical item into several words and cover all its shades of meaning. The option of paraphrase may reduce the degree of transparency in Target Text (TT) since the addition of a paraphrase alerts the TL readers that the lexical item in question does not exist in their cultural matrix. Further, the strategy of cultural borrowing entails carrying across the meaning of cultural specifics verbatim into the TT. It thus involves the insertion of footnotes having explanatory material, and transliteration. This strategy may break the flow of thoughts of the TL readers since they will have to consult the footnotes while reading. Besides, the translator may run the risk of producing an inadequate definition of the culture-specific item in the footnote. Translation by omission is given due attention in this research as a strategy conducive to creating a smooth and readable Target Text.  Translators should pay heed to the fact that this strategy is not a pretext to evade complex and awkward words and expressions; rather this strategy is justifiably adopted to prevent any degree of miscomprehension on the part of the TL readers. The strategy of compensation is demonstrated in this study. Translators are recommended to heed it since it seeks to create an understandable imitation of the Source Text.

Non-alcoholic fatty liver disease (NAFLD) is considered as a common cause of chronic liver disease. It is potentially progressive towards non-alcoholic steatohepatitis (NASH), hepatic fibrosis, cirrhosis and its complications including hepatocellular carcinoma (HCC). So, the need for predictive factors of NAFLD is important. Among the different serum markers in NAFLD, serum uric acid (SUA) has emerged as a possible predictor of severity of liver damage. This observational cross sectional study was carried out involving 100 patients from the department of gastroenterology, BSMMU, Dhaka, with the intention to determine the association of serum uric acid (SUA) level with non-alcoholic fatty liver disease. Among them, 55 were having NAFLD; and 45 subjects without NAFLD were considered as control. The diagnosis of NAFLD was based on the guidelines for the assessment and management of NAFLD in the Asia-pacific region. Serum uric acid, liver enzymes, glycaemic status, serum lipid profile and anthropometric measurements were compared between NAFLD group & control. The mean age was found 41.34 + 10.88 years in both the groups. Male were 62% & female were 38% among the study population. Forty percent of the study subjects were overweight, 23% were obese and 37% had normal body weight. NAFLD patients had significantly higher serum uric level (6.9 + 0.89 mg/dl) in comparison to non-NAFLD group (4.3 +0.87 mg/dl). The study showed that serum uric acid level was significantly associated with NAFLD. Serum uric acid may be used as a useful additional marker to assess the risk of development of NAFLD in the clinical setting of metabolic syndrome.

Published: March 2022

Impaired lipid metabolism in diabetic patients can lead to cardiovascular complications. Poor glycaemic control is associated with a significant increase in the risk of both patient’s morbidity and mortality. An early intervention to regulate circulating lipids has been found to lower the risk of cardiovascular problems and death. Glycated hemoglobin (HbA1c) is a reliable indicator of rising blood sugar levels. This hospital based observational study was conducted in the Department of Medicine, Sher-E-Bangla Medical College Hospital, Barisal from October 2014 to March 2015 over a period of 6 month to determine the correlation of glycemic control and lipid profile in patients with type 2 diabetes. A total of 110 type 2 diabe- tes mellitus(DM) patients of both sexes admitted to the Deapartment of Medicine of Sher-E- Bangla Medical College Hospital, Barisal, were recruited for this study. Following standard procedures and protocols, fasting blood sugar (FBS), blood sugar two hours after breakfast, Glycosylated Hemoglobin (HbA1c) and fasting lipid profile were measured. The age of respondents ranged from 34 to 70 years with the mean age of 54.35}8.02 years. Among the patients male were 70 (63.6%) and female were 40 (36.4%). Mean age at diagnosis of DM and duration of DM was 47.07}6.03 years and 7.27}3.41 years, respectively. Mean body mass index (BMI), FBS and HbA1c were 25.02}5.22 kg/m2, 8.06}2.01 mmol/L and 8.34}1.9 % respectively. Significant positive correlation of HbA1c and FBS with BMI, total cholester- ol(TC), triglyceride(TG), low density lipoprotein(LDL-C) and negative correlation with high density lipoprotein (HDL-C) was found. Significantly higher TC, TG and LDL-C and lower HDL-C were found in poor glycemic control (HbA1c ≥ 7) group than good glycemic control (HbA1c < 7 ) group. The results of this study showed that , higher levels of glycemic parame- ters are significantly associated with dyslipidemia. These findings also indicate that HbA1c can be utilized for screening of high risk diabetic patients for early diagnosis of dyslipidemia and timely intervention with lipid lowering drugs.

Comparison of CKD-EPI (Chronic Kidney Disease Epidemiology Collaboration) formula based eGFR (estimated glomerular filtration rate) with C-G (Cockcroft-Gaul) and MDRD (Modification of Diet in Renal Disease) formula based eGFR in adult Bangladeshi population
Authors: Chowdhury Jenat Zareen , Alam Mohammad Masum , Mollah Forhadul Hoque
Published: March 2022

Glomerular filtration rate (GFR) is the most important and accurate measure of overall kidney functions both in good health and disease because it is the sum of the filtration rates in each of the functioning nephrons .Different GFR measuring methods have some limitations.The objective of this study was to compare the CKD-EPI formula based eGFR with that of Cock- croft- Gault formula & 4 variable MDRD formula based eGFR.This Cross-sectional analytical study was done in the Department of Biochemistry & Molecular biology, BSMMU September during the period of July 2017 to August 2018. Serum creatinine was measured and eGFR by MDRD, CKD-EPI and Cockcroft-Gault formula was calculated using the respective equations on online calculator. Comparison of eGFR values between CKD-EPI & MDRD formula and between CKD-EPI & Cockcroft-Gault formula were done among different groups. Compari- son was done by Bland Altman agreement test to see the agreement on the measurement of GFR between three equation based eGFR method. Pearson‘s correlation test revealed a positive correlation between C-G and CKD-EPI (r = 0.779), but a stronger correlation between MDRD and CKD-EPI (r = 0.934). Bland-Altman plot showed strong agreement between CKD-EPI & 4–variable MDRD than between CKD-EPI & C-G formula. From this study we may conclude CKD-EPI and MDRD formula showed better agreement than between CKD-EPI and Cockcroft-Gault formula. So, this study suggests that CKD-EPI and MDRD equations can be used to estimate GFR more effectively than Cockcroft-Gault equation in Bangladeshi population.

Authors: Hussain Mahfuza , Amin Md Nurul , Islam Md Rafiqul
Published: March 2022

Background & Objective: Hand, foot and mouth disease (HFMD) is a contagious disease of children, occurs primarily under five years of age, characterized by a history of brief febrile illness and a typical skin rash over hands and feet with or without sores in mouth, caused usually by Coxsackievirus A16 viruses. It is mainly the disease of tropical and subtropical countries and bears a complex-relation with meteorological variables, like temperature, rainfall and relative humidity, although no study has yet been done in Bangladesh to explain the complex relationship of the disease with these variables. This study sought to describe the occurrence of HFMD and its association with meteorological factors in Dhaka city.

Methods: The present cross-sectional study collected data of 231 HFMD cases from the records of the daily register of Out-patient Department of Dhaka Shisu Hospital, Dhaka between January 2018 to December 2019. According to the study protocol a child was identified as having HFMD who had a history of brief febrile illness accompanied by a typical skin rash with or without mouth ulcers. Total number of cases treated monthly at OPD during the period were also recorded. Meteorological data were provided by Bangladesh Meteorological Department, which among others, included monthly average temperature, relative humidity and amount of rainfall. While the outcome variable was monthly number of HFMD cases, the predictive variables were average temperature, humidity and rainfall during the study period.

Result: Majority (85.3%) children in the present study was < 5 years old. A male preponderance was observed in the series (60%) with male to ratio being 3:2. A clustering of HFMD cases was observed to occur between June to October when monthly average temperature, total rainfall and humidity all were at their maximum compared to those found between November to April. The clustering of cases was more intense in the year 2019 than that in the year 2018. During the period average monthly temperature was 29.20C, average rainfall was 62.6% (238 mm) of the total annual precipitation and mean relative humidity was 79%. The proportion of HFMD cases out of total cases treated during the period was 2.2% in 2018 and was 4.1% in 2019, which in the dry season (November to April) was 0.4% and 0.5% in 2018 and 2019 respectively.

Conclusion: The study concluded that majority of the HFMD cases occur under five years of age and boys are more likely to have the infection than the girls. A seasonality of HFMD occurrence is observed with a higher number of cases occurring in the monsoon season and fewer cases in the dry season. Clustering of HFMD cases occur between May to October when monthly average temperature, total rainfall and humidity all are at peak compared to those in November to April of the year.

Authors: Wang Benlin , Li Qi , Sun Yang , Tong Xiaoguang
Published: March 2022

Objective : The clinical management paradigm of skull base chordomas is still challenging. Surgical resection plays an important role of affecting the prognosis. Endonasal endoscopic approach (EEA) has gradually become the preferred surgical approach in most cases, but traditional transcranial surgery cannot be completely replaced. This study presents a comparison of the results of the two surgical strategies and a summary of the treatment algorithms for skull base chordomas.Methods : We retrospectively analyzed the surgical outcomes and follow-up data of 48 patients with skull base chordomas diagnosed pathologically who received transnasal midline approaches (TMA) and transcranial lateral approaches (TLA) from 2010 to 2020.Results : Among the 48 patients, 36 cases were adopted TMA and 12 cases were performed with TLA. In terms of gross total resection (GTR) rate, 27.8% in TMA and 16.7% in TLA and with EEA alone it was increased to 38.9%, while 29.7% in primary surgery. In TMA, the cerebrospinal fluid (CSF) leak remains the most common complication (13 cases, 36.1%), other main complications included death, cranial nerve palsy, hypopituitarism, all the comparisons were no statistical significance. The Karnofsky Performance Scale scores in TMA were all better than those in TLA at different time, and the overall survival (OS) and recurrence free survival/progression free survival was just the reverse.Conclusion : The EEA for skull base chordomas resection has improved the GTR rate, but transcranial approach is still an alternative approach. It is necessary to select an appropriate surgical approach based on the location and the pattern of tumor growth in order to obtain the best surgical outcomes.

Koi carp is one of the most sensitive variants of common carp Cyprinus carpio to cyprinid herpesvirus 3, commonly known as koi herpesvirus (KHV). Given that this species is traded at high prices throughout the world, intra vitam assays for detecting KHV in targeted fish with a high detection efficiency are essential. In this study, 4 intra vitam assays were compared with regard to their efficiency of detecting KHV in koi carp on each day after viral exposure via experimental infection. The results indicated that PCR from the gills and scales sampled by biopsy using dissecting scissors and forceps, respectively, can detect KHV for apparently longer periods than the other assays. This study also suggests that a PCR detection assay for environmental samples could be developed as a convenient intra vitam assay to confirm the presence of virus in environments inhabited by virus-shedding fish.
War and Schooling in South Sudan, 2013-2016
Authors: Mayai Augustino Ting
Published: March 2022

South Sudan was embroiled in a civil war from mid-December 2013 to mid-September 2018. Nearly 400,000 people died, and several million were displaced. The economy nearly collapsed as the nation's output was severely reduced, causing inflation to soar. While prior research on the immediate humanitarian crisis in South Sudan has focused on forced displacement and food insecurity, there is little information available about the long-term impact the war had on human capital accumulation in this context. This analysis exploits spatial variation in exposure to violence to estimate the causal impact of the recent civil war on primary school enrollment as a proxy for measuring human capital accumulation. Results based on the difference-in-differences methodology indicate a statistically significant relationship between school enrollment and the war. The study shows that schools located in the South Sudanese war zones lost 85 children per year on average, or 18.5 percent of total enrollment. The diminishing trends in girls' enrollment are unrelated to the war, which is not surprising; social barriers, including gendered domestic roles, early marriage, and out-of-wedlock pregnancies, have long impeded female educational opportunities in South Sudan. These effects are robust to a number of specifications, including holding constant school-level fixed effects and adjusting for the standard errors. The article presents important policy implications for education and the labor market, both locally and internationally.

The level of technical skills affects the integration of migrants into the host country’s labour market. This study investigated the relationship between Zimbabwean school-leaver migrants’ self-perception of technical skills and occupational realities. A mixed-method research design was used in this study and systematic sampling was used to select respondents for the study. Questionnaires were administered on 60 respondents to collect quantitative data whilst 19 respondents provided qualitative data using semi-structured interviews. Findings suggested that most low-skilled migrants from Zimbabwe faced several challenges including failure to secure formal employment, obtain work and residence permits because of their low-level technical skills and qualifications. This challenge further affects migrants’ social integration and economic status in the host country. Findings also revealed that there are no strategies to provide skills to migrant labour to assist them to join the mainstream labour market and reduce their life challenges in Botswana.

Published: March 2022

Vehicular Ad-hoc Network (VANET) is an essential part of futuristic Intelligent Transportation Systems. VANET can improve the overall traffic control system and reduce road accident deaths by providing remote health monitoring in hazardous conditions to outdoor patients. Nowadays, vehicles have become so intelligent that they can sense patient health data and transmit it to a nearby ambulance or hospital in emergency or road accident situations. Health professionals can provide appropriate treatment without wasting critical time in further testing. Developing an efficient and reliable routing solution is a significant research problem for VANET based health monitoring applications because of time-sensitives. Routing approaches to reduce the transmission delay for critical applications are based on topological, geographical, clustering, and flooding techniques. This article has evaluated and compared widely used topological and geographical routing protocols for data-based VANETs health monitoring applications. A comprehensive analysis is performed on Ad hoc On-Demand Distance Vector (AODV), Destination-Sequenced Distance-Vector (DSDV), Optimized Link State Routing (OLSR), Greedy Perimeter Stateless Routing (GPSR), Greedy Perimeter Stateless Routing-Modified (GPSR-M), and Max duration-Minangle Greedy Perimeter Stateless
Routing (MM-GPSR) protocols with different numbers of nodes, CBR connections, communication range and
packet size on Network Simulator (NS-3.23) and Simulation of Urban Mobility (SUMO) platforms. Experimental results give useful knowledge in analyzing routing protocols for VANET's data-based smart health monitoring
applications.
Weed Community Composition in Simple and More Diverse Cropping Systems
Authors: Nguyen Huong T. X. , Liebman Matt
Published: March 2022

Weed communities in three cropping systems suitable for the Midwestern USA were studied from 2017 to 2020 to examine how crop diversification and the intensity of herbicide use affected weed community diversity, stand density, and aboveground mass. A baseline 2-year cropping system with corn (Zea mays L.) and soybean (Glycine max (L.) Merr.) grown in alternate years was diversified with cool-season crops, namely oat (Avena sativa L.), red clover (Trifolium pratense L.), and alfalfa (Medicago sativa L.) in 3-and 4-year systems. Herbicide was not applied in the cool-season crops. Changing weed management regime from broadcast to banded application and interrow cultivation in corn and omitting herbicide in cool-season crops of the 3- and 4-year rotations resulted in an overall reduction of herbicide a.i mass. The reduction in the mass of herbicide active ingredients was associated with increases in weed stand density, aboveground mass, and community diversity. Increased weed abundance under herbicide mass reduction was not associated with crop yield loss. In the cool-season crops phases of the 3- and 4-year rotations, weed emergence was increased but weed growth was not, as compared with the warm-season crop environments. The dominance of aggressive weed species such as common waterhemp (Amaranthus tuberculatus (Moq ex DC) J.D. Sauer) and common lambsquarter (Chenopodium album L.) tended to be greater in corn and soybean phases of the rotations than in oat, red clover, and alfalfa.

Despite magnesium based metal materials are widely used in bone defect repair, there are still various deficiencies, and their properties need to be optimized. Composites synthesized with magnesium based metal as matrix are the research hotspot, and the host immune response after biomaterial implantation is very important for bone binding. By studying the immunoregulation of bone biomaterials, it can regulate the immune response in the process of osteogenesis and create a good local immune microenvironment, which is conducive to biomaterials to reduce inflammatory response and promote good bone binding. This article introduces the osteogenic mechanism of magnesium based metal materials and its regulation on bone immune microenvironment in detail.
