2师生互动的实证研究:中芬法澳四国中学数学课堂中的师生互动显示文摘师生互动是中学数学课堂中的关键教学行为。通过选取中国、芬兰、法国和澳大利亚四个国家中学数学课堂录像进行实证研究,探寻出中芬法澳课堂中师生互动模式的可能形态:整体态势上中国课堂中的师生互动较为静态,并表现出教师主导性;而芬法澳三国的师生互动更为动态。互动模式1:教师提问-学生回答是各国主导的师生互动模式,中国尤甚;中国的互动模式1与芬法澳迥异,主要表现在互动对象上;互动模式2:学生提问-教师回答在中国课堂几乎缺失;互动模式3:教师讲解-学生听讲是各国课堂知识传输的主要媒介,中国课堂中尤甚;互动模式4:学生做题-教师辅导中的教师辅导,在中国主要表现为全班集中讲解,体现出集体主义色彩,在芬法澳课堂中主要是个性化、针对性的小组或个别辅导;互动模式5:课堂管理在芬法澳课堂是重要的师生互动形式,中国课堂缺失。于国文 曹一鸣 David Clarke Man Ching Esther Chan 2019全球教育展望2019,48,1:27

4Pancreatic enzyme replacement therapy for pancreatic exocrine insufficiency in the 21^(st) century显示文摘Restitution of normal fat absorption in exocrine pancreatic insufficiency remains an elusive goal. Although many patients achieve satisfactory clinical results with enzyme therapy, few experience normalization of fat absorption, and many, if not most, will require individualized therapy. Increasing the quantity of lipase administered rarely eliminates steatorrhea but increases the cost of therapy. Enteric coated enzyme microbead formulations tend to separate from nutrients in the stomach precluding coordinated emptying of enzymes and nutrients. Unprotected enzymes mix well and empty with nutrients but are inactivated at pH 4 or below. We describe approaches for improving the results of enzyme therapy including changing to, or adding, a different product, adding non-enteric coated enzymes,(e.g., giving unprotected enzymes at the start of the mealand acid-protected formulations later), use of antisecretory drugs and/or antacids, and changing the timing of enzyme administration. Because considerable lipid is emptied in the first postprandial hour, it is prudent to start therapy with enteric coated microbead prior to the meal so that some enzymes are available during that first hour. Patients with hyperacidity may benefit from adjuvant antisecretory therapy to reduce the duodenal acid load and possibly also sodium bicarbonate to prevent duodenal acidity. Comparative studies of clinical effectiveness of different formulations as well as the characteristics of dispersion, emptying, and dissolution of enteric-coated microspheres of different diameter and density are needed; many such studies have been completed but not yet made public. We discuss the history of pancreatic enzyme therapy and describe current use of modern preparations, approaches to overcoming unsatisfactory clinical responses, as well as studies needed to be able to provide reliably effective therapy.Tony Trang Johanna Chan David Y Graham 2014World Journal of Gastroenterology2014,20,33:17

8A 2D DEM-LBM study on soil behaviour due to locally injected fluid显示文摘Leakage from underground pipes could result in foundations being undermined and cause damage to adjacent infrastructure. Soil particles surrounding the leaking area could be mobilised, displaced, and even washed out of the soil matrix by the leaking fluid, generating a void or cavity. A two-dimensional simulation using a coupled discrete element method and lattice Boltzmann method (DEM-LBM) has been used to investigate the behaviour of a soil bed subject to a locally injected fluid, which represents a leak in a pipe. Various values of inter-particle surface energy were also adopted to model the mechanical effects of cohesive particles. The results suggest that the inter-particle surface energy greatly influences the bed response with respect to the leaking fluid, including the excess pressure initiating the cavity, the cavity shape and its evolution rate.Xilin Cui Jun Li Andrew Chan David Chapman 2012Particuology2012,10,2:6

10PEPT study of particle motion for different riser exit geometries显示文摘Laboratory and industrial risers are equipped with exits of many different layouts,and numerous publications discuss the influence of riser exit geometry on local and overall solids hydrodynamics in the riser.The present paper reviews literature findings-mostly based upon indirect experimental techniques and often somewhat contradictory.Direct measurement of particle velocity and particle occupancy near and in the riser exit provide a better indication of the effect of riser exit geometry.Positron Emission Particle Tracking(PEPT)was used in this work for the first time to investigate the exit region of the riser.An abrupt or sharp exit causes particles to be knocked out of the gas flow,so forming a recirculation or reflux region in the upper part of the riser.This is much less pronounced with a curved or gradual exit.Chian Wen Chan Anke Brems Shiva Mahmoudi Jan Baeyens Jonathan Seville David Parker Thomas Leadbeater Joseph Gargiuli 2010Particuology2010,8,6:5

14Mitochondrial neuronal uncoupling proteins:a target for potential disease-modification in Parkinson’s disease Philip显示文摘This review gives a brief insight into the role of mitochondrial dysfunction and oxidative stress in the converging pathogenic processes involved in Parkinson’s disease(PD).Mitochondria provide cellular energy in the form of ATP via oxidative phosphorylation,but as an integral part of this process,superoxides and other reactive oxygen species are also produced.Excessive free radical production contributes to oxidative stress.Cells have evolved to handle such stress via various endogenous anti-oxidant proteins.One such family of proteins is the mitochondrial uncoupling proteins(UCPs),which are anion carriers located in the mitochondrial inner membrane.There are five known homologues(UCP1 to 5),of which UCP4 and 5 are predominantly expressed in neural cells.In a series of previous publications,we have shown how these neuronal UCPs respond to 1-methyl-4-phenylpyridinium(MPP+;toxic metabolite of MPTP)and dopamine-induced toxicity to alleviate neuronal cell death by preserving ATP levels and mitochondrial membrane potential,and reducing oxidative stress.We also showed how their expression can be influenced by nuclear factor kappa-B(NF-B)signaling pathway specifically in UCP4.Furthermore,we previously reported an interesting link between PD and metabolic processes through the protective effects of leptin(hormone produced by adipocytes)acting via UCP2 against MPP+-induced toxicity.There is increasing evidence that these endogenous neuronal UCPs can play a vital role to protect neurons against various pathogenic stresses including those associated with PD.Their expression,which can be induced,may well be a potential therapeutic target for various drugs to alleviate the harmful effects of pathogenic processes in PD and hence modify the progression of this disease.WL Ho Jessica WM Ho Hui-Fang Liu Danny HF So Zero HM Tse Koon-Ho Chan David B Ramsden Shu-Leong Ho 2012Translational Neurodegeneration2012,1,1:3
