Posterior quadrantic disconnection maintains the activity of isolated temporal-parietal-occipital nerve tissue: neuroprotective measures in the surgical treatment of epilepsy

Extensive lesions involving the posterior quadrant of the cerebral hemisphere （temporal, parietal, and occipital lobes） induce intractable epilepsy. These patients are potential candidates for surgical treatmenttu. Maintenance of isolated nerve tissue activity after surgery plays a crucial role in the neuroprotective effects of neurosurgery treatment. Disconnection surgery of the posterior quadrant is used to completely isolate nerve fibers, while blood supply at the isolated lobes is maintained. Subsequently, cavities caused by cystic or necrotic nerve tissues should be reduced as much as possible,

A real-time measuring technology for studying distortion of hydraulic turbine blade castings during heat treatment process

During heat treatment process, the distortion behavior inevitably appears in hydraulic turbine blade castings. In this research, a technology was developed for real-time measurement of the distortion in hydraulic turbine blade castings at the still air cooling and forced air cooling stages during heat treatment process. The method was used to measure the distortion behavior at the cooling stages in both normalizing and tempering processes. At the normalization, the distortion at the blade comer near outlet side undergoes four stages with alternating bending along positive and negative directions. At the tempering stage, the distortion could be divided into two steps. The temperature difference between the two surfaces of blade casting was employed to analyze the distortion mechanism. The measured results could be applied to guide the production, and the machining allowance could be reduced by controlling the distortion behavior.

Why Should We Bother on Measurement in Wastewater Treatment Operation?

The question of wastewater treatment and control is reflected from a very specific viewpoint: the low priority given to accurate and useful measurements within wastewater treatment. The matter is discussed from four various perspectives, that may be labelled “Legal understanding”;“Needs for accurate measurement results already in the planning and design stage”;“The measurement problem and human behaviour”;“The understanding of the short term and long term dynamics and changes in pollution and flow loads on a wastewater treatment plant (WWTP)”. All these aspects bring about much improved needs for an accurate and frequent measurement scheme both for pollutants and flows entering a WWTP. The conclusion is stated as follows: A far more and well elaborated on-line measurement system at the plants would become a needed tool for improved water environment protection at lower costs.

基于UDEC的岩脉侵入角度对隧道安全影响分析

为探究岩脉侵入角度对隧道开挖的影响,文章以泸石高速石棉隧道开挖时地层遭遇不同角度岩脉侵入为工程背景,通过UDEC离散元计算,总结岩脉侵入角度对隧道开挖的影响,给出有效处理措施,并得出以下结论:岩脉和被侵入岩体界面易发生塑性滑移,隧道开挖后岩脉区围岩变形最大,且岩脉区围岩有开裂、滑移和隆起现象,围岩变形随角度的减小而减小。边墙与仰拱连接处轴力、剪力、弯矩均最大,安全系数最小,三种工况均在0.3左右。衬砌轴力、剪力的最大值随角度减小而增大,弯矩受角度的影响较小。岩脉区域的安全系数在向着岩脉倾斜方向更小。岩脉侵入区域隧道开挖应采用岩脉区域局部注浆、封闭仰拱、增大衬砌厚度三种方法来加固围岩和提高衬砌承载能力。

Hydrodynamics research of wastewater treatment bioreactors

To optimize the design and improve the performance of wastewater treatment bioreactors,the review concerning the hydrodynamics explored by theoretical equations,process experiments,modeling of the hydrodynamics and flow field measurement is presented. Results of different kinds of experiments show that the hydrodynamic characteristics can affect sludge characteristics,mass transfer and reactor performance significantly. Along with the development of theoretical equations,turbulence models including large eddy simulation models and Reynolds-averaged Navier-Stokes (RANS) models are widely used at present. Standard and modified k-ε models are the most widely used eddy viscosity turbulence models for simulating flows in bioreactors. Numerical simulation of hydrodynamics is proved to be efficient for optimizing design and operation. The development of measurement techniques with high accuracy and low intrusion enables the flow filed in the bioreactors to be transparent. Integration of both numerical simulation and experimental measurement can describe the hydrodynamics very well.

BACKGROUND Quality of life(QoL)outcomes are a focal endpoint of cancer treatment strategies.AIM To externally validate the Moroccan Arabic version of the European Organization for Research and Treatment of Cancer(EORTC)QoL Questionnaire(QLQ)for colorectal cancer(CRC)patients(CR29).METHODS Both Moroccan Arabic modules of QLQ-CR29 and QLQ-C30 were administered to Moroccan CRC.Psychometric properties were retested by measuring Cronbach’s alpha coefficient for reliability and Intraclass correlation coefficient(ICC)to examine test-retest reproducibility.The multitrait-scaling analysis was performed to demonstrate the validity of the instrument and known-groups comparison was used to test the score’s ability to discriminate between different groups of patients.RESULTS In total,221 patients were included in our study and 34 patients completed the questionnaire twice.The Urinary Frequency scale and Stool Frequency scale had good internal consistency with alpha Cronbach coefficients of 0.79 and 0.83 respectively,while the same coefficients were moderately lower for the Blood and Mucus in Stool scale(0.61)and the Body Image scale(0.67).The ICCs ranged from 0.88 to 1 indicating good to excellent reproducibility.In multitrait scaling analyses,the criterion for item convergent and divergent validity was satisfactory.The known-group comparison showed statistically significant differences between patients according to age,gender,stoma status,tumor location,and radiotherapy.CONCLUSION The Moroccan Arabic version of the EORTC QLQ-CR29 is a valid and reliable tool that can be used safely for research and clinical purposes in Moroccan CRC patients.

Application of Preventive Treatment Theory in the Treatment of Pelvic Inflammatory Disease

With a history of more than two thousand years, the theory of preventative treatment has been closely followed by the development of modern medical theories on the basis of inheritance by medical experts in the past dynasties, which has been constantly improved and enriched, and deeply applied in the prevention and treatment of serious and multiple diseases. It has achieved great benefits. For women with gynecological diseases, pelvic inflammatory disease patients accounted for a large proportion. Due to the lack of specificity in diagnosis and treatment, the condition is lingering and difficult to cure, so it seriously reduces the quality of life of women, thus affecting the harmony of family and society. From the perspective of prevention, according to the characteristics of each stage of the disease, this paper put forward substantive prevention suggestions and targeted treatment methods, ensuring preventing before disease, preventing progress after disease, and preventing reoccurring after recovery. It has important practical significance for the prevention and treatment of pelvic inflammatory diseases, as well as the development and inheritance of traditional Chinese medicine.
