| 1 | Metallic Functionally Graded Materials:A Specific Class of Advanced Composites显示文摘Functionally graded materials,including their characterization,properties and production methods are a new rapidly developing field of materials science.The aims of this review are to systematize the basic production techniques for manufacturing functionally graded materials.Attention is paid to the principles for obtaining graded structure mainly in the metal based functionally graded materials.Several unpublished results obtained by the authors have been discussed briefly.Experimental methods and theoretical analysis for qualitative and quantitative estimation of graded properties have also been presented.The article can be useful for people who work in the field of functionally graded structures and materials,and who need a compact informative review of recent experimental and theoretical activity in this area. | Jerzy J.Sobczak Ludmil Drenchev | 2013 | Journal of Materials Science & Technology2013，29，4： | 10 |
| 2 | An overview of separation by magnetically stabilized beds:State-of-the-art and potential applications显示文摘This article deals with problems relevant to implementation of magnetically stabilized beds (MSB) as separation devices. The main issues discussed are: bed mechanics, bed structure, possibilities to create controllable filter media, etc. As examples several separation techniques are discussed: dust filtration—magnetic and non-magnetic, ion-exchange, copper cementation, yeast filtration from biological liquids, particle separation by density and magnetic properties, dangerous wastes removal. Only key publications will be quoted that provide a basis for further reading and study and relevant information. | Jordan Hristov Ludmil Fachikov | 2007 | China Particuology2007，5，1： | 6 |
| 3 | A CASCADIC MULTIGRID ALGORITHM FOR COMPUTING THE FIEDLER VECTOR OF GRAPH LAPLACIANS显示文摘在这份报纸,也就是,我们为一个图拉普拉斯算符的 Fiedler 向量的快计算开发一个 cascadic multigrid 算法相应于第二个最小的特征值的特徵向量。这向量被发现了在象图划分并且图绘画那样的地里有应用程序。算法基于变粗的一个重边是一条完全代数学的途径计划并且 pointwise 为精炼变光滑。获得理论卓见,我们也为椭圆形的特征值问题和表演在几何背景考虑相关 cascadic multigrid 方法它在某些假设下面的一致集中。数字测试为计算几张实际的图的 Fiedler 向量被介绍,并且数字结果显示出我们的建议 cascadic multigrid 算法的效率和 optimality。[从作者抽象] | John C.

| 5 | Giant retroperitoneal abscess following necrotizing pancreatitis treated with internal drainage显示文摘BACKGROUND:Retroperitoneal abscess is a dangerous complication of the inflammatory process in organs. The pancreas reacts by enzymatic autodigestion and inflammation to external and internal factors:alcohol abuse,trauma,biliary stones,and viral infections. Chronic pancreatitis and formation of pseudocysts are late complications.The diffuse spread of pancreatic inflammation may form a retroperitoneal phlegmon.A better outcome is the limitation of the process by capsule formation-retroperitoneal abscess. METHODS:A 62-year-old man,with a history of alcohol abuse,was admitted for intermittent abdominal pain,fever, and significant weight loss.Previous medical consultations (laboratory tests,US,CT)confirmed chronic pancreatitis with pseudocyst formation.A new CT depicted a giant retroperitoneal abscess. RESULTS:After preoperative preparation with antibiotics, laparotomy and internal drainage-longitudinal cystoje- junostomy with Roux-en-Y loop were performed.At the 8th postoperative day the patient was in good condition. CONCLUSIONS:Giant retroperitoneal abscess is a dangerous pathology with significant mortality and morbidity.Diagnosis strongly necessitates operative intervention in order to evacuate and drain the space.Theseconditions include one internal drainage(in the GI tract) with the stomach,duodenum,or jejunum,which does not cause early and late GI discomfort and will gradually liquidate the cavity.We propose internal drainage with Roux-en-Y jejunal loop as the only method for accomplishing these conditions in cases of giant retroperitoneal abscesses. | Ludmil Marinov Veltchev Manol Anastasov Kalniev | 2009 | Hepatobiliary & Pancreatic Diseases International2009，8，5： | 2 |

| 13 | Local Fourier Analysis of Multigrid Methods with Polynomial Smoothers and Aggressive Coarsening显示文摘We focus on the study of multigrid methods with aggressive coarsening and polynomial smoothers for the solution of the linear systems corresponding to finite difference/element discretizations of the Laplace equation.Using local Fourier analysis we determine automatically the optimal values for the parameters involved in defining the polynomial smoothers and achieve fast convergence of cycles with aggressive coarsening.We also present numerical tests supporting the theoretical results and the heuristic ideas.The methods we introduce are highly parallelizable and efficient multigrid algorithms on structured and semi-structured grids in two and three spatial dimensions. | James Brannick Xiaozhe Hu Carmen Rodrigo Ludmil Zikatanov | 2015 | Numerical Mathematics(Theory,Methods and Applications)2015，8，1： | 1 |
