In the current study,a 0.3C-2Si-2Mn-0.28Mo (in wt%) steel with high hardenability was deformed at a relatively low temperature followed by isothermal static phase *** novel thermomechanical processing made it possible to successfully produce an ultrafine ferrite grained structure (～2 μm) in the absence of both dynamic phase transformation and controlled *** use of a model Ni-30Fe austenitic alloy showed that the low temperature deformation induced very fine intragranular defects throughout the microstructure,which would then act as fine spaced ferrite nucleation sites at an early stage of phase *** a result,the coarsening of ferrite was extremely limited during isothermal phase transformation,resulting a very fine ferrite grained structure;even nanoscale in the region of the prior austenite grain boundary.

Brain tumors incidence in pediatric age hasbeen estimated between 1.3 to 5% with a relativeincidence of 1.4 to 11% during the first year oflife; the improvement in instrumental deviceshas lead to a relative increase in precocious diag-nosis. The choice to study brain tumors of the firstyear of life as a separate topic from pediatric ageones depends on the observation that these le-sions have peculiar clinical, topographic and tis-sular characteristics. The survival rate of thesepatients is very poor if compared with that found

Background:Minimally invasive surgery(MIS)is the technique of choice in selected patients for the treatment of liver *** robotic approach is considered today the natural evolution of *** application of the robotic technique in liver transplantation(LT)has been recently evaluated,especially in the living *** aim of this paper is to review the current role of the MIS and robotic donor hepatectomy in the literature and to evaluate the possible future implication in the transplant ***:we conducted a narrative review using PubMed and Google Scholar for reports published so far,using the following keywords:minimally invasive liver surgery,laparoscopic liver surgery,robotic liver surgery,robotic living donation,laparoscopic donor hepatectomy and robotic donor ***:Several advantages have been claimed in favor of robotic surgery:three-dimensional(3-d)imaging with stable and high-definition view;a more rapid learning curve than the laparoscopic one;the lack of hand tremors and the freedom of *** to open surgery,the benefits showed in the studies evaluating the robotic approach in the living donation are:less postoperative pain,the shorter period before returning to normal activity despite sustaining longer operation ***,the 3-d and magnification view makes the technique excellent in distinguishing the right plane of transection,vascular and biliary anatomy,associated with high precision of the movements and a better bleeding control(essential for donor safety)and lower rate of vascular ***:The current literature does not fully support the superiority of the robotic approach versus laparoscopic or open method in living donor *** donor hepatectomy performed by teams with high expertise and in properly selected living donors is safe and ***,further data are necessary to evaluate properly the role of robotic surgery in the field of living donation.

ArbiTER(Arbitrary Topology Equation Reader)is a new code for solving linear eigenvalue problems arising from a broad range of physics and geometry *** primary application area envisioned is boundary plasma physics in magnetic confinement devices;however ArbiTER should be applicable to other science and engineering fields as *** code permits a variable numbers of dimensions,making possible application to both fluid and kinetic *** use of specialized equation and topology parsers permits a high degree of flexibility in specifying the physics and geometry.

AIM： To investigate the etiology, diagnosis, management and outcome of epiphora referrals to an oculoplastic ***： Retrospective chart review of patients referred for epiphora to an oculoplastic clinic between 2005 and 2009. Patient demographics, past history, ophthalmic examination, treatment and outcome were ***： There were 237 subjects with a primary complaint of epiphora. They included 130 （55%） females and 107 （45%） males with an average age of 55.9±25.9y. The most common cause of epiphora was lacrimal obstruction （46%）; followed by multifactorial epiphora （22%）, reflex tearing （22%） and eyelid malposition （11%）. differences in prevalence of etiology were noted in terms of age and gender distribution. Of the 182 （77%） patients who returned for follow up, 41 （23%） reported a complete resolution and 102 （56%） reported a significant improvement in their ***： Epiphora is a common condition with many causes. A thorough history and examination are required to provide the appropriate treatment tailored to the underlying cause.
