This paper investigated the mutual interaction between two extra-thin line fires under different wind speeds of 0.4, 0.6, 0.8, 1.0 and 1.2 m/s by using a small-scale tunnel. The experiments involved spacing distances 5, 10, 15, 20, 25, 30, 35 40 cm, heat release rates 19.4, 25.7 32.7 kW, respectively. results show that flame merging probability increase, as speed or rate increases. Compared with rectangular square fires, height length will be smaller at same for fires. Meanwhile, decrease...
Background: Our study examines the relationship between gastroesophageal reflux disease (GERD) and small intestinal bacterial overgrowth (SIBO), focusing on potential impact of acid-suppressive drugs. We also explore changes in gut microbiota metabolism patients with both conditions. Methods: This included from Department Gastroenterology, Beijing Shijitan Hospital, February 2021 November 2023. All underwent assessments including questionnaires, hydrogen methane breath tests, gastroscopy....
Reflection of a rightward-moving shock over steady oblique shock, equivalent to shock-on-shock interaction, is typically studied with post-formed waves. Law, Felthun and Skews ( Shock Waves , vol. 13, 2003, pp. 381–394) reported expansion fan (PFEF) reflection for second-family incident shock. Here, we show that PFEF also exists first-family We derive the critical condition in speed Mach number angle plane. Our findings indicate emergence near type post-I region. Numerical simulations reveal...
The solar trough concentrator is used to increase the radiation intensity on absorbers for water heating, desalination, or power generation purposes. In this study, optical performances of four concentrators, viz. parabolic (PTC), compound (CPC), surface uniform (SUC), and trapezoid (TTC), are simulated using Monte Carlo Ray Tracing method. Mathematical models concentrators first established. distributions their receivers then simulated. heating finally compared. results show that, as a...
Aims:To evaluate the clinical efficacy of Human Urinary Kallidinogenase (HUK) and Maixuekang capsule in treatment acute ischemic stroke (AIS) patients . Methods: In this study, from January 2016 to July ,60 with were enrolled 56 complete information whom 21 received HUK+ basic treatment(HUK group),16 + treatment(HUK+ group),19 treatment(control group) 0.15 PNA unit HUK injection plus 100 ml saline intravenous infusion was performed group group, once a day for 14 consecutive days 0.75g...
The ([Formula: see text])-dimensional B-type Kadomtsev–Petviashvili (BKP) equation is utilized to depict weakly dispersive waves propagating in the fluid mechanics. According [Formula: text]-soliton solutions, resonance Y-shaped soliton and its interaction with other local wave solutions of BKP are derived by introducing constraint conditions. These types hybrid exhibit complex phenomenon among solitons, breather waves, line solitary high-order lump waves. dynamic behaviors such analyzed illustrated.
Through the merits of arbitrary three-dimensional (3D) fabrication ability and nanoscale resolution two-photon polymerization, we demonstrated a fully encircled polymerized microfiber Bragg grating using 3D femtosecond laser nanofabrication. In order to generate strong enough polymer units around surface, possess possible smaller unit pitch structure size, composition photoresist dimensions were both experimentally optimized. A fast-curing, high-adhesion, great-heat-resistant acrylate...
The reflection of a rightward-moving oblique shock (RMOS) belonging to the first family, over an initially steady wave (SOSW) produced by wedge, is studied in this paper. To cover all possibilities, problem divided into pre-shock problem, for which incident assumed reflect pre-interaction part SOSW, and post-shock post-interaction part. Such division, together with definition equivalent defined on reference frame co-moving nominal intersection point two waves, allows us connect patterns six...
Inhomogeneous broadening in disordered crystals has been widely recognized as a successful approach to enhance the spectral bandwidth of rare earth ions optical spectra, and Yb3+-doped mixed laser are known ultrafast pulse materials have emerged hotspot recently. In this study, sodium gadolinium/lanthanum double molybdate NaGd(1–x)La(x)(MoO4)2 with x = 0.3, 0.5, 0.9 were grown by Czochralski (Cz) method. The structure as-grown was investigated XRD, SEM, FT-IR, Raman experiments....
The motivation of instructors has been found to have a significant impact on students' enthusiasm learn second language, but less attention paid the English Foreign Language (EFL) teachers, especially in Chinese environment where plays role. In order lay groundwork for formulation suggestions how increase teacher and consequently boost standard instruction student performance, this study explores at university level China. 203 native EFL who are currently employed institutions China’s...
The reflection of rightward moving shocks (RMSs) belonging to the first and second families, over an initially steady oblique shock wave (SOSW) produced by a wedge, is studied in this paper. Various possible combinations primary (reflection at intersection point RMS SOSW) secondary (reflection, on reflected waves reflection) are identified transition conditions studied. For family, problem can be shown equivalent interference problem. If wedge angle large, then interaction with two incident...
