Experimental Study and Application of TPO Waterproofing Membrane Lapping Process Parameters.

Taking the TPO waterproofing membrane as an example, this paper studies the influence of temperature, speed and welding pressure on the welding quality of a TPO waterproofing membrane lap area through a peel test and a water impermeability test, determines the optimal construction process, and observes and compares the permeable path through laser confocal microscope. Finally, it is applied to the actual effect test in the project. The results show that the welding pressure test tool for the lap area of the waterproofing membrane is designed to meet the welding work test requirements of various lap areas of the waterproofing membrane.

Numerical analysis of coal rock gas dynamics disaster risk in coal thickness variation area and research on prevention and control.

During the mining process of deep coal mines, the coal thickness variation zone is highly prone to coal-rock-gas dynamic disasters. In order to promote the sustainable development of coal resource exploitation and utilization, the numerical simulation was carried out based on COMSOL software. The dynamic disaster mechanism of coal rock gas in the coal thickness variation area was revealed and corresponding prevention and control measures were given.

Analysis and application of PPV vibration reduction technology in subgrade step blasting - a case study.

In this study, the synergistic mechanism of charge structure, stemming materials and blasting parameters in blasting vibration control was explored by means of field experiment and numerical simulation. The following study has been carried out: (1) Based on the control variable method, the dynamic response difference between the interval charge and the continuous charge is quantitatively analyzed, and the optimal charge structure is determined; (2) On the basis of interval charge, the optimization of two kinds of stemming materials is carried out by finite element analysis; (3) Through field parameter optimization experiments, it is proved that when the inter-hole delay is 33 ms and the inter-row delay is 86 ms, the PPV is the lowest. This study can provide experience for similar open-pit blasting projects.

Silent magnetic resonance angiography diagnostic value of intracranial unruptured aneurysms.

Silent magnetic resonance angiography (S-MRA) is primarily utilized to assess the blood flow in aneurysms and parent vessels of treated intracranial aneurysms. This study aimed to compare the diagnostic value of S-MRA and three-dimensional time of flight (3D-TOF) MRA for unruptured intracranial aneurysms. We included patients diagnosed with unruptured intracranial aneurysms using digital subtraction angiography (DSA) who subsequently underwent S-MRA and 3D-TOF MRA.

Small subcortical ischemic infarction and other DWI lesions establish predictive model for MES.

Objective: The relationship between small subcortical ischemic infarction remains poorly characterized. Therefore, the present study aimed to investigate the association between artery-to-artery embolization and small subcortical infarctions.

Methods: This retrospective observational cross-sectional study enrolling 230 patients with acute middle cerebral artery (MCA) stroke classified into the microembolic signals-positive (MES+) and MES-negative (MES-) groups.

Study on influencing factors and prevention measures of coal-rock-gas compound dynamic disaster in deep coal mine mining.

Because coal seam mining with high geostress and high gas pressure is prone to coal-rock-gas compound dynamic disasters, a disaster energy equation considering the influence of roof elastic energy is established, and a disaster energy criterion considering the influence of roof elastic energy is derived and introduced into COMSOL software to conduct numerical simulations of coal seam mining under different geostress and gas pressures. The study revealed that the increase of ground stress reduces the gas pressure required for disaster occurrence. When the gas pressure reaches a certain value, the disaster will occur even if the ground stress is very small.

Mortality from cerebrovascular diseases in China: Exploration of recent and future trends.

Background: Cerebrovascular disease (CVD) ranks among the foremost factors responsible for mortality on a global scale. The mortality patterns of CVDs and temporal trends in China need to be well-illustrated and updated.

Methods: We collected mortality data on patients with CVD from Chinese Center for Disease Control and Prevention's Disease Surveillance Points (CDC-DSP) system.

Diffusion-weighted imaging hyperintensities during the chronic stage of intracerebral hemorrhage with surgery: A new clinical situation or post-surgery artifact?

Background And Objective: Diffusion-weighted imaging (DWI) hyperintensities were occasionally seen at previous hematoma in patients several months after intracerebral hemorrhage with surgery. Whether they are newly occurred clinical situations or post-surgery changes is unknown. This study aims to investigate the prevalence and possible mechanisms for this phenomenon.

Monogenic basis of young-onset cryptogenic stroke: a multicenter study.

Background: The prevalence of stroke in young adults is increasing. We investigated the monogenic basis of young adult cryptogenic stroke patients.

Arterial Spin Labeling-Based MRI Estimation of Penumbral Tissue in Acute Ischemic Stroke.

Background: Arterial spin labeling (ASL) has shown potential for the assessment of penumbral tissue in patients with acute ischemic stroke (AIS). The postlabeling delay (PLD) parameter is sensitive to arterial transit delays and influences cerebral blood flow measurements.

Feasibility Study on the Steel-Plastic Geogrid Instead of Wire Mesh for Bolt Mesh Supporting.

Wire mesh is a common material for bolt mesh supporting structures, but its application in engineering has revealed many defects. At the same time, with the development of new materials for civil engineering, the new material mesh performance and cost show outstanding advantages over wire mesh. In this paper, the feasibility of replacing wire mesh with steel-plastic geogrid as an alternative material is carefully studied through indoor tests and field applications.
