During the hydraulic fracturing process, high speed fluid which contained solid particles would result in erosion between and inner surface of tubing or casing cause great threat to service safety downhole-tubular string. In this paper, experiment Q125HC steel were carried out different carrying velocity, angle sand content. The results showed that within 0-90°, rate first increased, continuously come up a "peak value", then let while impact is also velocity has big on steel.
Analyzing the spatial and temporal patterns in rice production trade southwestern region of China main rice-producing countries Southeast Asia provides a reference for development food security. The study aims to analyze costs import export volumes between Southwest Asia. For current study, sown area, yield, production, import/export data were collected 1978-2021 based on FAO statistical database. Comparative analyses planted unit area total export, market share, potential, competency...
To enhance the core employability of college students in application-oriented universities and optimize employment guidance work universities. This study takes Chengdu Technological University as an example conducts a systematic analysis current situation students’ problems existing services. The discovers that there are still deficiencies innovation ability, interdisciplinary ability workplace adaptability during process university. research findings indicate strategies such deepening...
Building upon Heidegger's profound conception of time, Lacan ingeniously developed a sociologically grounded framework 'intersubjectivity'. Notably, the key distinction between Lacanian intersubjectivity and Husserl's concept is stark. lacks epistemological substance that inherently present in idea. Through meticulous comparative analysis Lacan's temporal frameworks, complemented by detailed phenomenological reconstruction theory this - depth study thoroughly elucidates application logical...
This study aims to evaluate the predictive value of risk factors for postpartum hemorrhage (PPH) following vaginal delivery, with a special focus on impact intrauterine device (IUD) usage in context recent policy changes allowing more childbirths China. A total 6879 women who underwent deliveries from January 2021 December 2023 Lianyungang regional maternal care system and met inclusion exclusion criteria were enrolled. case-control design was employed, comprising 524 PPH (blood loss ≥500...
Transcranial alternating current stimulation (tACS), a noninvasive neuromodulation technique, has been demonstrated to improve cognitive function. Recent advances in protocols have introduced an accelerated intervention paradigm, which shown promising therapeutic outcomes across various brain modalities. Despite these encouraging developments enhancement, there remains significant gap the literature regarding potential applications of tACS substance use disorders. We present case 22-year-old...
Abstract The drill pipe joint cracked during service, resulting in failure. geometric dimensions of thread, chemical composition and microstructure the were tested. dimensions, found to comply with standard requirements. whole macroscopic fracture didn’t show obvious corrosion product. tensile properties, Charpy impact Brinell hardness met Microstructure was analyzed, which showed a typical erosion micromorphology parallel arranged fatigue strips. Through simulation analysis, it that...
T-joint welding is a key manufacturing process of large storage tanks. However, complex residual stresses are generated and have great effect on the structural integrity The high stress caused by discontinuous structure may result in tank cracking failure. In this work, distributions inner surface, outer thickness direction were investigated using finite element method indentation test method. local PWHT with different heating temperatures, rates, widths distribution was also discussed....
Super 13Cr, as an economy stainless steel (SS) for oil country tubular goods, needs stable corrosion resistance in high-pressure and high-temperature (HPHT) downhole medium. Severe plastic deformation (SPD) are the surface modification technology to improve mechanical properties, fatigue behavior of metals, shot peening (SP) has been most widely used SPD process. However, there quite limited studies about microsutructure evolution, residual stress, SP-treated martensitic SS. In this study,...
Investigating neurophysiological markers linked to impulsivity in individuals with gambling and methamphetamine addiction using resting-state EEG data offers valuable insights into the underlying mechanisms associated addiction. This study aims use explore connection between various types of different aspects impulsivity. Participants from methamphetamine, gambling, healthy control groups (abbreviation: MA, GB, HC) underwent recordings completed measures Group differences trait scores...
Modified acellular solutions are prepared using the liquid–liquid mixing method, with same nominal ion concentrations as conventional simulated body fluids detailed in ISO 23317.
The traditional sports training coach is one-to-one or one-to-many face-to-face training, it not only take the limitation of time and place, but also high cost resources nervous. In order to solve this problem, a growing number professional national began apply motion capture training. Kinect through accurate grasp athlete body contour position determine player action, action corresponding role operation. This article based on device, combined with feature activities, provide effective...
Methamphetamine use is a serious problem in China. Compulsory isolation detoxification the main treatment measure for drug dependents, whereas psychological interventions compulsory centers are extremely inadequate. The current study aimed to examine effects of mindfulness-based relapse prevention (MBRP) on methamphetamine dependence patients Chinese institutions. Forty-one dependent received 16-sessions MBRP 8 weeks and assessments were conducted at baseline, 4-, 8-week (after whole...
With the exploitation of oil and gas resources, water environment high-Ca2+ high-Cl− stratum puts forward high safety requirements for tubular columns. This paper simulates underground by using high-temperature high-pressure autoclaves, combines electrochemical research results, analyzes effect flow rate on corrosion behavior P110 steel in a 7.5 g/L Ca2+ + 128 Cl− simulated stratum. The results show that presence promotes acidification solution accelerates dissolution steel. increased fluid,...
