Comment les « spoutniks » sont montés au cielles rendements record du grand bond en avant

RésuméÀ travers l'étude du lancement de « spoutniks » agricoles qui visent à obtenir des rendements record durant le grand bond en avant de 1958, l'auteur s'intéresse au rôle que les cadres ruraux de base ont joué dans ce mouvement de compétition nationale. Soumis aux pressionsadministratives, qui, de haut en bas, s'exercent à tous les échelons de la hiérarchie, ces cadres ont été entraînés dans une spirale de surenchère qui les a conduits à imposer aux foyers paysans d'atteindre des objectifs toujours plus irréalistes. Face à cette démesure, les protagonistes concernés n'ont pu faire autrement que de tricher. Les paysans ont été incapables de s'opposer à ces cadres villageois auxquels, pourtant, ils n'accordaient que peu de considération en raison de l'incompétence dont ils faisaient preuve.AbstractForward This study of the launching of “agricultural sputniks” for obtaining record crops focuses on the role played by low-level rural officials during the Great Leap Forward in 1958. Under pressure from administrative authorities ­ a pressure exercised from the top downwards on all levels in the hierarchy ­ these officials were caught up in a spiral of making overestimates. This led them to force peasant households to reach objectives ever farther from reality. To meet these disproportionate demands, peasants could but cheat. They were unable to oppose village authorities even though they had little esteem for them because of their proven incompetence

NEOLIBERALISM, URBANISM AND THE PLIGHT OF CONSTRUCTION WORKERS IN CHINA

Thirty years after China's Reform and Opening, China has become not only the world's workshop, but also the world's largest construction site. In large and small construction sites throughout the country, 40 million "peasant workers" are building world-class metropolises such as Beijing and Shanghai, creating China's economic miracle of rapid growth, and making many Chinese people euphoric about "the rise of a powerful state" (daguo jueqi). From the perspective of Marxist and post-Marxist theory, we try to understand these "peasant workers" in the process of working-class formation and China's overall social transformation. Through this study, we reflect on the question of neoliberalism, urbanism and the formation of a new working class in China. </p

Gas Fluidization and Pneumatic Conveying in Confined Beds: A Numerical Study

The fluidization phenomena for gas-fine particle two-phase flow is numerically simulated in confined fluidized bed based on two-fluid model, applying body-fitted coordination for the irregular geometry zone in this work. The simulation was performed either with a partially packed fluidized bed in the bottom part applying various superficial gas velocities in bubbling region, which is used to study the bubbles formation and the average porosity in the packed zone, or with a whole packed fluidized bed applying various solid flux rates in pneumatic region, which is used to investigate the mechanism in the packed bed. The void fraction of the fine-particles confined bed as a function of flow velocity is compared with experimental results by G. Donsi etc.(1). The numerical pressure drop in the fully packed bed is compared with experimental results by Yulong Ding etc. (2)

Multiphase CFD Simulation of Solid Propellant Combustion in a Small Gun Chamber

The interior ballistics simulations in 9 mm small gun chamber were conducted by implementing the process into the mixture multiphase model of Fluent V6.3 platform. The pressure of the combustion chamber, the velocity, and the travel of the projectile were investigated. The performance of the process, namely, the maximum pressure, the muzzle velocity, and the duration of the process was assessed. The calculation method is validated by the comparison of the numerical simulations results in the small gun with practical tests, and with lumped-parameter model results. In the current numerical study, both the characteristics and the performance of the interior ballistic process were reasonably predicted compared with the practical tests results. The impact of the weight charge on the interior ballistic performances was investigated. It has been found that the maximum pressure and the muzzle velocity increase with the increase of the charge weight

The splicing of backscattered scanning electron microscopy method used on evaluation of microscopic pore characteristics in shale sample and compared with results from other methods

The splicing of backscattered scanning electron microscopy (SB-SEM) method was applied to evaluate the microscopic pore characteristics of the Lower Silurian Longmaxi Shale samples from Py1 well in Southeast Chongqing, China. The results from SB-SEM, including frequencies, volumes and specific surface areas of organic and inorganic pores with different sizes, were compared with those of low temperature nitrogen adsorption/desorption (LTNA) and mercury intrusion porosimetry (MIP). The results show that the changes in organic and inorganic surface porosity with increasing image area estimated from the SB-SEM method become almost stable when the SB-SEM image areas are larger than 0.4 mm, which indicates that the heterogeneities of organic and inorganic pore volumes in shale samples can be largely overcome. This method is suitable for evaluating the microscopic pore characteristics of shale samples. Although the SB-SEM underestimates the frequencies, volumes and specific surface areas of pores smaller than its resolution, it can obtain these characteristics of pores larger than 100 nm in width, which are not effectively evaluated by the LTNA method and are underestimated by the MIP method

Endoscopic rhizotomy for chronic lumbar zygapophysial joint pain.

BACKGROUND: Chronic lumbar zygapophysial joint pain is a common cause of chronic low back pain. Percutaneous radiofrequency ablation (RFA) is one of the effective management options; however, the results from the traditional RFA need to be improved in certain cases. The aim of this study is to investigate the effect of percutaneous radiofrequency ablation under endoscopic guidance (ERFA) for chronic low back pain secondary to facet joint arthritis. METHODS: This is a prospective study enrolled 60 patients. The cases were randomized into two groups: 30 patients in the control group underwent traditional percutaneous radiofrequency ablation, others underwent ERFA. The lumbar visual analog scale (VAS), MacNab score, and postoperative complications were used to evaluate the outcomes. All outcome assessments were performed at postoperative 1 day, 1 month, 3 months, 6 months, and 12 months. RESULTS: There was no difference between the two groups in preoperative VAS (P \u3e 0.05). VAS scores, except the postoperative first day, in all other postoperative time points were significantly lower than preoperative values each in both groups (P \u3c 0.05). There was no significant difference between the two groups in VAS at 1 day, 1 month, and 3 months after surgery (P \u3e 0.05). However, the EFRA demonstrated significant benefits at the time points of 3 months and 6 months (P \u3e 0.05). The MacNab scores of 1-year follow-up in the ERFA group were higher than that in the control group (P \u3c 0.05). The incidence of complications in the ERFA group was significantly less than that in the control group (P \u3c 0.05). CONCLUSIONS: ERFA may achieve more accurate and definite denervation on the nerves, which leads to longer lasting pain relief

Developing A Fair Individualized Polysocial Risk Score (iPsRS) for Identifying Increased Social Risk of Hospitalizations in Patients with Type 2 Diabetes (T2D)

Background: Racial and ethnic minority groups and individuals facing social disadvantages, which often stem from their social determinants of health (SDoH), bear a disproportionate burden of type 2 diabetes (T2D) and its complications. It is therefore crucial to implement effective social risk management strategies at the point of care. Objective: To develop an EHR-based machine learning (ML) analytical pipeline to identify the unmet social needs associated with hospitalization risk in patients with T2D. Methods: We identified 10,192 T2D patients from the EHR data (from 2012 to 2022) from the University of Florida Health Integrated Data Repository, including contextual SDoH (e.g., neighborhood deprivation) and individual-level SDoH (e.g., housing stability). We developed an electronic health records (EHR)-based machine learning (ML) analytic pipeline, namely individualized polysocial risk score (iPsRS), to identify high social risk associated with hospitalizations in T2D patients, along with explainable AI (XAI) techniques and fairness assessment and optimization. Results: Our iPsRS achieved a C statistic of 0.72 in predicting 1-year hospitalization after fairness optimization across racial-ethnic groups. The iPsRS showed excellent utility for capturing individuals at high hospitalization risk; the actual 1-year hospitalization rate in the top 5% of iPsRS was ~13 times as high as the bottom decile. Conclusion: Our ML pipeline iPsRS can fairly and accurately screen for patients who have increased social risk leading to hospitalization in T2D patients

Cervical posterior longitudinal ligament ossification : Microscopy-assisted anterior corpectomy and fusion.

OBJECTIVE: To explore the clinical efficacy and safety of microscopy-assisted anterior corpectomy and fusion for cervical ossification of the posterior longitudinal ligament (OPLL). METHODS: A retrospective review of 32 cervical OPLL patients who underwent microscopy-assisted anterior corpectomy and fusion from June 2012 to March 2017 was carried out. Patients were evaluated with outcome metrics: Japanese Orthopaedic Association (JOA) scores (17 points method), visual analog scale (VAS), and radiographic parameters of the lordotic angle. The complications during treatment and follow-up were recorded. RESULTS: This study included 32 patients (15 males and 17 females) with a mean age of 58.3 ± 2.9 years (range 42-68 years). The average duration of follow-up was 19.0 ± 3.5 months (range 11-46 months). The scores of postoperative VAS significantly decreased (P \u3c 0.05). The average JOA score at 12 months postoperation significantly improved (p \u3c 0.05). The lordotic angle increased after surgery (P \u3c 0.05). There was no titanium mesh subsidence, no pseudarthrosis or hardware failure at 1‑year follow-up. COMPLICATIONS: One cerebrospinal fluid leakage in the surgery was managed using a gelatine sponge and the patient recovered after 1 week: One patient developed laryngeal nerve injury symptom of hoarseness and recovered spontaneously in 2 weeks without intervention and 1 patient suffered slight postoperative infection. There was no worsening of neurological function. CONCLUSION: Microscopy-assisted anterior cervical anterior surgery appears to be a safe and effective treatment option for selected cases of cervical posterior longitudinal ligament ossification
