3581   Laparoscopic gonadectomy in paediatric and adolescent girls with intersex disorders Laparoscopic gonadectomy in paediatric and adolescent girls with intersex disorders    2003 Gonadectomy is indicated in some children and teenagers with intersex disorders. Traditionally, this has been performed by laparotomy. This paper is a retrospective evaluation of laparoscopic gonadectomy in 10 girls (age range 8 to 17 years). Clinical records were reviewed for diagnosis, indication for surgery, complications and recovery period. Operative notes were reviewed for details of technique and complications. In all cases, the procedure was uncomplicated and the maximum hospital stay wa... 查看全文

3582   Poly(N-isopropylacrylamide) grafted to a strongly charged backbone: Thermoresponsive behavior. in aqueous solution Poly(N-isopropylacrylamide) grafted to a strongly charged backbone: Thermoresponsive behavior. in aqueous solution Hongqian Bao, Jinhua Hu, Leong Huat Gan and Lin Li    2004 The thermoresponsive properties in aqueous solution of the graft copolymer poly(acrylic acid-co-2-acrylamido-2-methyl propane sulfonic acid)-g-poly(N-isopropylacrylamide) [P(AA-co-AMPSA)-g-PNIPAM] were studied and compared to the corresponding behavior. of the poly(acrylic acid)-g-poly(N-isopropylacrylamide) (PAA-g-PNIPAM) graft product. Both products contain about 40% (w/w) of PNIPAM, whereas the backbone, P(AA-co-AMPSA), of the first copolymer contains about 40% of AMPSA mole units. The strong... 查看全文

3583   Breast MRI Wire-Guided Excisional Biopsy: Specimen Size as Compared to Mammogram Wire-Guided Excisional Biopsy and Implications for Use Breast MRI Wire-Guided Excisional Biopsy: Specimen Size as Compared to Mammogram Wire-Guided Excisional Biopsy and Implications for Use Sara H. Javid, Joseph W. Carlson, Judy E. Garber, Robyn L. Birdwell, Susan Lester, Stuart Lipsitz;Me    2007 Background  Breast magnetic resonance imaging (MRI) has been implemented as a screening tool for early detection and as a diagnostic test in the management of breast cancer. Lesions identified by MRI but not amenable to conventional biopsy techniques require MRI wire-guided excisional biopsy (MRIbx). We hypothesized that more tissue would be resected with MRIbx compared to Mammobx. We also sought to evaluate factors that might predict the prese... 查看全文

3584   Novel method for current transformer saturation countermeasure based on the ratio of differential current and restraint current Novel method for current transformer saturation countermeasure based on the ratio of differential current and restraint current    2009 Based on the different variation characteristics of the ratio of differential current and restraint current during internal fault and external fault with current transformer saturation, a new saturation criterion called ratio restraint coefficient method is presented. Meanwhile a criterion of identifying the change of the differential current's polarity is added to solve the problem of opening the differential protection during the internal fault with current transformer saturation.

3589   Some Problems of the Cracking Mechanism of Hydrocarbons Some Problems of the Cracking Mechanism of Hydrocarbons R. S. MAGARIL    1970 The model of the cracking mechanism of olefins proposed by Voevodsky should lead to a strong dependence of olefin cracking products on temperature and pressure. This was not observed. The author proposes a chain olefin cracking mechanism when chains are being formed via a series of displacement and addition reactions of the radicals on π-bonds. Some influence of the paraffinic and cycloparaffinic products on the kinetics and mechanism is considered. Decomposition of olefins (primary cracking pr... 查看全文

3591   Recurrent yolk sac tumor following resection of a neonatal immature gastric teratoma Recurrent yolk sac tumor following resection of a neonatal immature gastric teratoma Etsuji Ukiyama, Masao Endo, Fumiko Yoshida, Tohru Tezuka, Kyoko Kudo, Seiji Sato, Seiya Akatsuka;Jun    2005 Gastric teratomas are very rare and usually benign. Only a few cases of gastric teratomas with malignant components have been reported. This report describes recurrence of a yolk sac tumor following resection of a neonatal immature gastric teratoma. Gastric teratoma recurring as a malignant lesion has not been previously reported. Recurrence of immature gastric teratomas should be considered, and a periodic follow-up check with alpha-fetoprotein level should be mandatory. 查看全文

3592   New approach using the relativistic Hamilton-Jacobi equation to evaluate the correct energy levels for the hydrogen atom New approach using the relativistic Hamilton-Jacobi equation to evaluate the correct energy levels for the hydrogen atom    2006 The aim of the present study is to propose a model based on classical field theory to study atomic and molecular systems. Starting from the basic principles of the special relativity theory (SRT), the model is described by taking the interaction between two moving particles with the standing wave radiated from the particles in the four-dimensional space-time. According to the classical theory of fields, the geometrical properties of the solutions are governed by a classical-like equation of moti... 查看全文

Read    1997 Cheatle's (1920–21), transabdominal posterior preperitoneal groin herniorrhaphy was ignored. Rediscovered in 1936 by Henry, it languished until Stoppa (1965) used it for GPRVS. Since Cheatle cited no references, the antecedent literature has been reviewed to determine prior contributions. Transabdominal intraperitoneal relief of incarcerated bowel by median section began in 1800 B.C. Reintroduced by Annandale in 1873, it was applied to elective repair of reducible f... 查看全文

KPN consist of concurrent processes communicating with unidirectional FIFO channels (Kahn Channels). KPN processes are self scheduled and dependent only on the input data stream, which makes them particularly suitable for media processing and other data streaming applications. On the other hand, to shorten time-to-market projections, embedded systems designers are designing complex Multi-Processor ... 查看全文

TAU-LINES: A NEW HYBRID APPROACH TO THE NUMERICAL TREATMENT OF CRACK PROBLEMS BASED ON THE TAU METHOD.    1986 A new hybrid computational technique based on E. L. Ortiz' recursive formulation of the Tau method is introduced in this paper and applied to some model singular boundary value problems which are relevant to fracture mechanics (modes I and III). This technique, which we call Tau-lines, combines the method of lines with the Tau method. The former is used in the construction of a system of coupled ordinary differential equations which is the discretized model of a given partial differential equati... 查看全文

3600   Representing Action Model Updates Representing Action Model Updates Jan Van Eijck    2008 First, we will show how bisimulation can be used to simplify Kripke models by replacing each state in the model by its bisimilarity class, and we will present and implement an algorithm for carrying this out. Action models are a special kind of Kripke models, where the valuations are replaced by precondition formulas. A wide range of communicative actions can be modelled as updates with action models. We define a datatype for action models, and then turn to the definition and implementation of a 查看全文

This method is formulated based on the homogeneous cylindrical coordinates and Bryant angles transformation matrices and thus termed 'C-B notation.' At first, shape matrix for a binary link is derived. Then, the characteristic matrices for the five most commonly used kinematic lower pairs-revolute (R), prismatic (P), cylindrical (C), helical (H), and spherical (S)-are formulated. The 'exact' joint positions, that is, the actual loc... 查看全文
