Fire incidents in energy storage stations are frequent, posing significant firefighting safety risks. To simulate the fire characteristics and inhibition performances by fine water mist for lithium-ion battery packs an energy-storage cabin, PyroSim software is used to build a 1:1 experimental geometry model of containerized cabin. The simulation reveals five stages their characteristic parameter variations during incident: initial temperature rise, flame generation, spread, stable...
Abstract Backgrounds Parkinson’s disease (PD) is a common age-related neurodegenerative disorder worldwide. This research aimed to investigate the effects and mechanism underlying long non-coding RNA metastasis-associated lung adenocarcinoma transcript 1 (MALAT1) in PD. Methods SK-N-SH SK-N-BE cells were treated with MPP + establish -stimulated cell model of PD, MALAT1 expression was determined. Then, depletion on proliferation apoptosis determined Besides, correlations between...
The presence of sudden onset to maximal deficit (SOTMD) in patients with acute basilar artery occlusion often results more severe outcomes. However, the effect endovascular therapy on SOTMD and whether outcome is affected by onset-to-puncture time remain unclear.
In this study, while aiming at the prevention of fire accidents in underground commercial streets, an street is selected as a research object, and building numerically simulated using PyroSim software. Fire simulation scenarios are divided according to different zones by analyzing temperature, carbon monoxide (CO) concentration, visibility smoke layer inside building. The available safe evacuation time calculated critical hazard judgment conditions. We found that when flue gas temperature CO...
OBJECTIVE First-pass effect (FPE), defined as successful reperfusion (modified Thrombolysis in Cerebral Infarction score 2b–3) with a single stent retriever attempt without salvage treatment, has not been fully identified patients acute basilar artery occlusion (BAO). The authors’ aim was to assess the impact of FPE on efficacy and safety for BAO. METHODS authors included data from Acute Basilar Artery Occlusion Study (BASILAR) about who underwent mechanical thrombectomy within 24 hours...
Objective It is difficult to make the differential diagnosis between tuberculous meningitis (TBM) and cryptococcal (CM) when smear negative. The objective of this study was create a diagnostic rule for differentiating TBM from CM in adult HIV-negative patients based on clinical laboratory features. Methods data 219 satisfying criteria (n=100) (n=119) hospitalized at Third Affiliated Hospital Sun Yat-Sen University during period 2000-2009 were retrospectively analyzed. Features found be...
To thoroughly study the extinguishing effect of a high-pressure water mist fire system when transformer occurs, 3D experimental model is established in this work by employing Fire Dynamics Simulator (FDS) software. More specifically, setting different parameters, process with presence both diverse ambient temperatures and sprinkler laying conditions simulated. In addition, employed implementation strategies systematically analyzed. The extracted results show that source farther away from...
As an important part of the power system, oil-immersed transformers have a complex structure with large oil storage capacity and high-risk factor.The fire simulation software PyroSim was used to simulate burning process under different scenarios, in order investigate vulnerability transformer fire.Surface according results: from oilimmersed tends form plume ignite other components such as bushings.The ambient wind speed where is located has effect on spread fire's flames; rates heat release...
Fire accidents due to oil-immersed transformers seriously threaten the safe operation of power systems. In this paper, similarity principle was used design a high-pressure water mist fire-extinguishing test platform for small-scale transformer fire, and method achieved good fire extinguishing effect. The results indicate that deflagration phenomenon, lasting about 2–4 s, could be observed after activating system; flame temperature rose rapidly at first, then dropped sharply, finally cooled...
Background This study aimed to investigate the association between hyperdense basilar artery sign (HBAS) on non-enhanced computed tomography (CT) and clinical outcomes in patients with acute occlusion (BAO) who underwent endovascular treatment (EVT). Methods Eligible EVT due BAO January 2014 May 2019 were divided into two groups based HBAS. HBAS was assessed by neuroradiologists using five grades nonenhanced CT. The primary outcome a favorable functional (defined as modified Rankin Scale...
The combustion of lithium-ion batteries is characterized by fast ignition, prolonged duration, high temperature, release significant energy, and generation a large number toxic gases. Fine water mist has characteristics such as fire extinguishing efficiency environmental friendliness. In order to thoroughly investigate the temperature control effect fine on battery fires. This study employs numerical simulation methods, utilizing PyroSim software simulate process in energy storage...
Asymptomatic intracranial hemorrhage (aICH) is common after endovascular thrombectomy (EVT). Collateral circulation could modify the association between aICH with functional outcome and we aimed to investigate impact of systemic inflammation index on 3-month under different collateral circulation.
Oil-immersed transformer is the key equipment of power transmission, fire caused by its failure will cause huge economic losses.The aim this study to investigate combustion characteristics oil-immersed fires under different environmental conditions, and effectiveness high-pressure fine water spray on parameters.Numerical simulation using PyroSim software mist extinguishing effect -parameter optimisation, focusing at ambient temperatures (-5℃, 0℃, 5℃, 10℃, 20℃) wind speeds (0 m/s, 1 2 4 m/s)...
As the underground space is relatively closed compared to other buildings, hardly connected outside world through entrances and exits, which makes it difficult ventilate exchange heat with outside. In this case, easy cause a large number of casualties when fire breaks out. When happens smoke will be discharged merely by mechanical exhaust, air system should work simultaneously replenish oxygen inside. By setting four-group models, paper analyzes strategies for extraction makeup in...
Abstract In order to study the thermal environment and comfort of university classrooms, a long-term on-site classroom in Hefei area is carried out by combining questionnaires data collection. A sensory model applicable established, through analysis it found that measured neutral temperature lower than predicted under PMV model, corresponding 90% acceptable ranges models are 22.0~25.6°C 17.2-24.9°C respectively. Opening closing doors windows adding removing clothing preferred adaptive...
OBJECTIVE: Cryptococcal meningitis (CM) can present in a similar way to tuberculous (TBM), with chronic or subacute course, and clinical features CSF characteristics. It is difficult make differential diagnosis bwteen TBM CM when smear negative. BACKGROUND: To create diagnostic rule for differentiating from adults on the basis of laboratory features.
