Abstract The diffusion of fuel spray in swirl flow is vital for the combustion of diesel engine, however, the researches on this is still mysterious due to the obstacles on direct investigations on a real engine. The research of intake swirl in engine at present normally use CFD simulation or based on data analysis of combustion and exhaust emission, the specific mixing process of fuel in swirl flow still not very clear. In this paper, a rapid compression machine (RCM) with an optical combustion chamber was established with the mean compression velocity of 7.55 m/s. Three… More >

Abstract During the current epidemic, it is necessary to ensure the rehabilitation treatment of children with serious illness. At the same time, however, it is essential to effectively prevent cross-infection and prevent infections from occurring within the hospital setting. To resolve this contradiction, the rehabilitation department of Nanjing Children’s Hospital adjusted its bed allocation based on the queuing model, with reference to the regional source and classification of the children’s conditions in the rehabilitation department ward. The original triple rooms were transformed into a double room to enable the treatment of severely sick children coming from More >

Abstract Introduction: Patients with suboptimal semen parameters following vasectomy reversal represent a diagnostic and therapeutic challenge. This may be caused by either partial or complete anastomotic obstruction. Despite the relatively common clinical use of corticosteroids in this patient population, data remain sparse. Thus, we set out to evaluate the safety and efficacy of prednisone after vasectomy reversal.
Materials and methods: A chart review was performed from January 1, 2008 to September 30, 2018 to identify men in which prednisone was used for suspected anastomotic obstruction after vasectomy reversal. Obstruction was based on sub-optimal or decreasing semen parameters and… More >

Abstract Introduction: To investigate the relationship between socioeconomic factors, specifically insurance status, and kidney stones using a nationally representative cohort.
Materials and methods: A retrospective secondary data analysis of National Health and Nutrition Examination Survey (NHANES) data from 2007 to 2014 was performed. Using univariate statistics and multiple logistic regressions, we examined the relationship between socioeconomic factors and kidney stone history.
Results: The weighted national prevalence of nephrolithiasis between ages 20 and 64 was 7.7% of a population of over 95.3 million. Fifty-three percent of the total population was female. The mean age was 42 years and the mean… More >

Abstract Introduction: Data on the prevalence of lower urinary tract symptoms (LUTS) and urinary incontinence (UI) in Canada are dated. This study aims to describe the current prevalence of LUTS and UI, to assess the state of knowledge of these conditions, the treatment for them and the treatment experience of symptomatic persons.
Materials and methods: A nationally representative adult (≥ 18 years) sample was surveyed using a questionnaire based on the EPIC study. The margin of error associated with this probability-based sample was +/-3.1%, 19 times out of 20.
Results: Of the 1000 people contacted (52% female, 48% male),… More >

Abstract This study evaluated the survival effects of metronomic maintenance therapy with oral fluoropyrimidine in patients with stage III colorectal cancer (CRC) according to epidermal growth factor receptor (EGFR) expression. We enrolled 197 patients with stage III CRC who had undergone radical resection and FOLFOX regimen adjuvant chemotherapy. The clinicopathological features and effects of metronomic maintenance therapy with oral capecitabine (daily dose of 850 mg/m2 , twice daily, on days 1–14 every 3 weeks for 6 months) on survival according to treatment group and EGFR expression were analyzed. By conducting an in vitro cell line study… More >

Abstract COVID-19 disease has emerged as one of the life threatening threat to the society. A novel beta coronavirus causes it. It began as unidentified pneumonia of unknown etiology in Wuhan City, Hubei province in China emerged in December 2019. No vaccine has been produced till now. Mathematical models are used to study the impact of different measures used to decrease pandemic. Mathematical models have been designed to estimate the numbers of spreaders in different scenarios in the present manuscript. In the present manuscript, three different mathematical models have been proposed with different scenarios, such as More >

Abstract In recent years, the application of WSNs has been remarkably increased and notable developments and advances have been achieved in this regard. In particular, thanks to smart, cheaper and smaller nodes, different types of information can be detected and gathered in different environments and under different conditions. As the popularity of WSNs has increased, the problems and issues related to networks are examined and investigated. As a case in point, routing issue is one of the main challenges in this regard which has a direct impact on the performance of sensor networks. In WSN routing,… More >

Abstract In order to optimize heat transfer in a heat exchanger using an ARM (advanced RISC machine) core intelligent computer algorithm, a new type of controller has been designed. The whole control structure of the heat exchange unit has been conceived on the basis of seven functional modules, including data processing and output, human-computer interaction, alarm, and data communication. The main controller and communication controller have been used in a combined fashion and a new MCU (micro control unit) system scheme has been proposed accordingly. A fuzzy controller has been designed by using a fuzzy control More >

Abstract This is a newborn male prenatally diagnosed with severe right ventricular (RV) hypertrophy and depressed function, aneurysmal dilation of the main pulmonary artery and tachyarrhythmia. Postnatally, he required immediate intubation and inotropic support. Echocardiogram revealed a large dysplastic RV, absent pulmonary valve syndrome (APVS), markedly dilated pulmonary arteries and tricuspid atresia (TA). The trabecular portion of the RV was excessively trabeculated and severely dilated. Inflow and infundibular walls were thin, with multiple infundibular aneurysms. There was APVS with free regurgitation and massively dilated pulmonary arteries. The RV bulged into the LV, though there was no… More >
