Published: June 2021

Abstract
To improve in-tube evaporation heat transfer at low quality, a novel evaporator based on efficient flow pattern global construction heat transfer enhancement mechanism is built, called the efficient flow pattern global construction evaporator (EFGE). The numerical analysis and experimental study of the thermodynamic performance of the EFGE are performed. Results show that the evaporation heat transfer coefficient (HTC) of the EFGE is 0.34–1.04 times that of a common parallel flow evaporator (PFE) and the pressure drop of the EFGE is only 80–116% of that of a common PFE at quality 0.9. The theoretical nonuniformity of the evaporation HTC between low- and high-quality flow is approximately 12–67%, which 55–72% of the pressure drop. The numerical analysis results are in good agreement with the finding that the EFGE has better thermodynamic performance than the PFE in terms of friction power reduction and minimum entropy generation number.

Abstract
Objectives. Using transformational theory and Chaos the research intends to explain the impact of workplace bullying on dental profession, threat it poses to dental patient safety and investigating the power of perceived co-worker social support to diminish the aftermath of workplace bullying.Material and Methods. The study is quantitative, descriptive and causal in nature. Data were collected in two-time lags from 267 dental professionals by using convenience sampling technique.Results. Findings of the study indicates that the workplace bullying among dental professionals is strongly linked with job stress, turnover intention and job performance which in turn challenges the safety of patient. Perceived co-worker social support is directly linked with job performance and organizational citizenship behaviour. Study highlights the power of Perceived co-workers social support in weakening the relationship between workplace bullying and turnover intention and Job performance of victim of bullying.Conclusion. The role of Perceived co-worker support on victims diminishes the cost associated with intention to leave and Job performance, offering recommendations to health care managers and medical educationists. Anti-bullying policies should be communicated among dental students, across educational institute & implemented under strict supervision of institutional management. The issue should be taken seriously, proper allocation of time, resources, anti-bullying policies should be communicated, fellows should be encouraged to help victims to report act. Bullying culture blooming among health care providers challenges the quality care to patients, only by utilizing the significant role played by co-workers this research highlights ways to overcome risks to quality care and safety of patients.
Antenatal anticoagulant therapy and neonatal hemorrhagic syndrome. Case report.

Published: June 2021

Abstract
Neonatal hemorrhagic syndrome, which affects several principal organs during the early neonatal period, denotes a deficiency of vitamin K and coagulation factors, respectively.This article presents the case of a patient that gave birth at term, who had congenital heart disease and required several prior surgical interventions including corrected transposition of the great vessels via ventricular septal defect (VSD) repair, atrial septal defect (in childhood) and tricuspid valve replacement (6 years ago), mitral regurgitation (MR), grade I pulmonary regurgitation (PR), grade II mitral and tricuspid valve regurgitation, and grade II heart failure based on the New York Health Association (NYHA) classification. Throughout the pregnancy the patient administered large doses of anticoagulant, specifically Acenocumarolum, until the moment she gave birth. The vaginal delivery was spontaneous, contrary to the recommendations given to the pregnant woman in a secondary healthcare institution. At birth, the newborn was in satisfactory condition, with 8/9 on the Apgar score. However, the newborn’s condition worsened over time, suspected of having neonatal hemorrhagic syndrome caused by medications administered by the mother. Forty-eight hours after birth the newborn died.Anticoagulant therapy cannot be considered absolutely safe during pregnancy because it presents risks for the development of hemodynamic disorders, not only for the mother, but also for the newborn. In such cases, it is recommended that a multidisciplinary team work together to inform the mother about possible complications, collaboratively establish the duration of treatment with vitamin K antagonists (VKAs), establish a plan for monitoring the pregnancy and determining in which institution the mother and newborn can benefit from qualified medical assistance, taking into consideration the higher incidence of perinatal mortality in such cases (10-30%).

Published: June 2021

Abstract
BackgroundGait difficulties in Parkinson’s disease have been related to problems shifting center of gravity forward. We previously showed reduced forward stepping latencies for people with Parkinson’s disease after one session of adaptation to upward visual shifts, which produces downward motor after-effects and potentially shifts center of gravity forward. Here we tested if repeated prism adaptation improved gait and postural control in Parkinson’s disease through a parallel, double-blind, randomized, sham-controlled trial.MethodsWe recruited participants with idiopathic Parkinson’s disease aged 40 – 80 and meeting any one of three clinical criteria: 1) Hoehn and Yahr Stage II.5 – IV; 2) Scoring > 0 on the gait, freezing of gait, and/or postural stability items of the Movement Disorder Society Unified Parkinson’s Disease Rating Scale; or 3) Timed Up and Go > 12 seconds. Sealed envelope style randomization allocated participants to two weeks of twice-daily prism adaptation or sham treatment. Participants, care givers, and those assessing the outcomes were blinded to group assignment. Primary outcomes were changes in postural control measured using the Berg Balance Scale; and the Limits of Stability, Sensory Organisation, and Motor Control tests from the Smart EquiTest system. Secondary outcomes included other physiotherapy and questionnaire measures. Outcomes were assessed at the Dartmouth Hitchcock Medical Center immediately before and after the treatment period, with further long-term postal follow-up over two months. Outcomes were analysed using Analyses of Variance with follow-up t-tests. ResultsEighteen participants were allocated to undergo prism adaptation, of which sixteen were analysed. Thirteen participants were allocated to undergo sham treatment, and all were analysed. The prism adaptation group showed increased forward stepping velocity on the Limits of Stability test (Pre: M=2.33, SEM=0.24; post: M=2.88, SEM=0.26; t(15)=3.2, p=.005, d=.819). The sham group showed no such change (Pre: M=2.13, SEM=0.22; 1d post: M=2.24, SEM=0.22; t(13)=.636, p=.537, d=.176). However, there were no group differences for any other outcome measures, and no indications that prism adaptation produced functional improvements in posture, gait, or activities of daily living. ConclusionsPrism adaptation does not improve gait or postural control in Parkinson’s disease.

Abstract
IntroductionIn recent years, the prevalence of infertility has significantly increased and has become a global reproductive health problem. The female ovarian reserves have been shown to decrease progressively with an increase in age. Besides, the rate of embryo implantation and clinical pregnancy also decreases. Traditional Chinese medicine has been widely applied in assisted reproductive technology. It is reported to have a significant influence on improving the quality of oocytes, improving endometrial receptivity, increasing clinical pregnancy rate, reducing pregnancy-related complications, etc. Therefore, this study will investigate the effect of Guilu Xian, a traditional Chinese medicine formula on IVF-ET outcome in older women with low prognosis.Methods and analysisThis trial is a prospective, multicenter, randomized double-blind clinical trial. A total of 120 infertile patients with low prognosis and receiving IVF or ICSI in 3 public hospitals in China will be randomly divided into two parallel groups: Guilu Xian group (n = 60) and placebo group (n = 60). Patients in both groups will be treated with antagonist regimens to promote ovulation, and all the patients will be required to take the medication from the 2nd to 4th day of the menstrual cycle to the day of egg retrieval. A comparison of the total number of oocytes obtained, the fertilization rate, clinical pregnancy rate, embryo quality, embryo implantation rate and early spontaneous abortion rate between the experimental group and the placebo group will be performed. This study was registered in the Chinese Clinical Trials Registry Platform (ChiCTR1900028255).
Extended residual coherence with a financial application
Authors: Zhang Xuze , Kedem Benjamin 
Published: June 2021

Abstract
Residual coherence is a graphical tool for selecting potential second-order interaction terms as functions of a single time series and its lags. This paper extends the notion of residual coherence to account for interaction terms of multiple time series. Moreover, an alternative criterion, integrated spectrum, is proposed to facilitate this graphical selection. A financial market application shows that new insights can be gained regarding implied market volatility.
Estimating completion and breakoff functions in a business web survey
Authors: Žmuk Berislav 
Published: June 2021

Abstract
A business web survey should be of an appropriate length. On the one hand it should include all the questions which are important to the researcher, but on the other hand, it should not be too long as the breakoff rate in this case tends to be high, resulting in a low response rate. In consequence, the researcher is forced to invest more time and money in order to reach a sample size which would enable an appropriately performed statistical analysis. In this paper, completion and breakoff times are observed and compared across different questionnaire and respondent characteristics. A regression modelling approach has been adopted to estimate the completion and breakoff functions to help a researcher determine which respondents completed a questionnaire and which broke it off too quickly or too slowly. By omitting such respondents, a researcher is able to obtain the relevant estimates more efficiently. In addition, the completion and breakoff functions offer a better insight into the completion and breakoff development rates, allowing the researcher to make a better-informed decision as to whether the survey requires any modifications or not.
A Bayes algorithm for model compatibility and comparison of ARMA(p,q) models
Authors: Tripathi Praveen Kumar , Sen Rijji , Upadhyay S. K. 
Published: June 2021

Abstract
The paper presents a Bayes analysis of an autoregressive-moving average model and its components based on exact likelihood and weak priors for the parameters where the priors are defined so that they incorporate stationarity and invertibility restrictions naturally. A Gibbs-Metropolis hybrid scheme is used to draw posterior-based inferences for the models under consideration. The compatibility of the models with the data is examined using the Ljung-Box-Pierce chi-square-based statistic. The paper also compares different compatible models through the posterior predictive loss criterion in order to recommend the most appropriate one. For a numerical illustration of the above, data on the Indian gross domestic product growth rate at constant prices are considered. Differencing the data once prior to conducting the analysis ensured their stationarity. Retrospective short-term predictions of the data are provided based on the final recommended model. The considered methodology is expected to offer an easy and precise method for economic data analysis.
Spatial sampling methods modified by model use1
Authors: ak Tomasz B 
Published: June 2021

Abstract
Recent years have seen an intensive development in the field of spatial sampling methods, which generally focus on a balanced distribution of the sample in space. Adaptive sampling methods constitute another dynamic direction in the sampling theory. The issue raised in this article involves the combination of these directions. Five of the commonly known spatial sampling methods have been analysed. The experiment was designed to include statistical model in the sampling procedure. As in the case of adaptive methods, it serves to modify drawing probabilities during sampling. The necessary theory of this sampling modification has been developed and presented. An experiment using artificial data was conducted in order to analyse the efficiency of the model modification in comparison with the primary methods.
Quantitative analysis of the impacts of climate and land-cover changes on urban flood runoffs: a case of Dar es Salaam, Tanzania
Authors: Mzava Philip , Valimba Patrick , Nobert Joel 
Published: June 2021

Abstract
Over the past half-century, the risk of urban flooding in Dar es Salaam has increased due to changes in land cover coupled with climatic changes. This paper aimed to quantify the impacts of climate and land-cover changes on the magnitudes and frequencies of flood runoffs in urban Dar es Salaam, Tanzania. A calibrated and validated SWAT rainfall-runoff model was used to generate flood hydrographs for the period 1969–2050 using historical rainfall data and projected rainfall based on the CORDEX-Africa regional climate model. Results showed that climate change has a greater impact on change in peak flows than land-cover change when the two are treated separately in theory. It was observed that, in the past, the probability of occurrence of urban flooding in the study area was likely to be increased up to 1.5-fold by climate change relative to land-cover change. In the future, this figure is estimated to decrease to 1.1-fold. The coupled effects of climate and land-cover changes cause a much bigger impact on change in peak flows than any separate scenario; this scenario represents the actual scenario on the ground. From the combined effects of climate and land-cover changes, the magnitudes of mean peak flows were determined to increase between 34.4 and 58.6% in the future relative to the past. However, the change in peak flows from combined effects of climate and land-cover changes will decrease by 36.3% in the future relative to the past; owing to the lesser variations in climate and land-cover changes in the future compared with those of the past.

Published: June 2021

Abstract
Monitoring surface water provides vital information in water management; however, limited data is a fundamental challenge for most developing countries, such as Vietnam. Based on advanced remote sensing technologies, the authors proposed a methodology to process satellite images and use their outcomes to extract surface water in water resource management of Quang Nam province. Results of the proposed study show good agreement with in situ measurement data when the obtained Overall Accuracy and Kappa Coefficient were greater than 90% and 0.99, respectively. Three potential applications based on the surface water results are selected to discuss sustainable water management in Quang Nam province. Firstly, reservoir operating processes can be examined, enhanced, and even developed through long-term extracted water levels, which are the interpolation results between the extracted surface water area and the water level–area–volume curve. Secondly, the long-term morphological change for the Truong Giang river case between 1990 and 2019 can also be detected from the Water Frequency Index performance and provided additional information regarding permanent and seasonal water changes. Lastly, the flood inundation extent was extracted and separated from permanent water to assess the damage of the Mirinae typhoon on 2 November 2009 in terms of population and crop aspects.
