作者： TABESHPOUR m.R GOLAFSHANI A.A. SEIF m.S Department of Civil Engineering Sharif University of Technology P.O.Box 11365-9313 Tehran Iran Department of mechanical Engineering Sharif University of Technology P.O.Box 11365-9313 Tehran Iran

Compliant offshore structures are used for oil exploitation in deep water. Tension leg platform (TLP) is a suitable type for very deep water. The nonlinear dynamic response of TLP under random sea wave load is necessary for determining the maximum deformations and stresses. Accurate and reliable responses are needed for optimum design and control of the structure. In this paper nonlinear dynamic analysis of TLP is carried out in both time and frequency domains. The time history of random wave is generated based on pierson-moskowitz spectrum and acts on the structure in arbitrary direction. The hydrodynamic forces are calculated using the modified morison equation according to Airy’s linear wave theory. The power spectral densities (PSDs) of displacements, velocities and accelerations are calculated from nonlinear responses. The focus of the paper is on the comprehen-sive interpretation of the responses of the structure related to wave excitation and structural characteristics. As an example a case study is investigated and numerical results are discussed.

A theoretical and experimental study of the thermal decomposition of nitroguanidine(NQ) has been carried out. Various thermolysis channels were studied by quantum chemistry methods at the CCSD(or DLPNO-CCSD) level using the aug-cc-pVDZ basis set. It is shown that the lowest activation enthalpies(170-180kJ/mol) are characteristic of the reactions of NO2abstraction from the initial NQ and the reaction channel with the transfer of oxygen from the nitro group to carbon in the limiting stage. Additionally, the thermolysis of NQ was studied experimentally in a nonisothermal mode with heating rates from 1 to 10K/min. In these experiments, the weight loss of the sample, thermal effects, and mass spectra of the products were recorded. An analysis of the experimental data confirmed the results of a theoretical study of the mechanism of thermal decomposition of NQ. The main thermolysis products are N2O, HNCO, NH3, and NO2, which fully corresponds to quantum chemical calculations.

World Journal of Clinical Urology 2014年第2期3卷 54-65页

Numerous surgical modalities are available to treat adrenal lesions. minimally-invasive approaches for adrenalectomy are indicated in most circumstances, and new evidence continues to be accumulated. In this context, current indications for open surgical adrenalectomy(OS-A), minimally-invasive adrenalectomy(mI-A), and laparoendoscopic single-site adrenalectomy(LESS-A) remain unclear. A comprehensive Englishlanguage literature review was performed using mEDLINE/Pub mED to identify articles and guidelines pertinent to the surgical management of adrenal tumors. A comprehensive chart review was performed for three illustrative cases. Clinical recommendations were generated based on relevant literature and the expertise of the investigator group. mI-A offers advantages over OS-A in properly selected patients, who experience fewer complications, lower blood loss, and shorter hospital stays. Robot-assisted laparoscopic and retroperitoneoscopic adrenalectomy may offer advantages over transperitoneal surgery, and LESS-A may be an even less-invasive option that will require further evaluation. mI-A remains the surgical treatment of choice for most adrenal lesions. Tumor size and stage are the primary indications for selecting alternative treatment modalities. OS-A remains the gold standard for large tumors(> 10 cm) and suspected or known advanced stage malignancy. LESS-A appears to be an appropriate initial approach for small tumors(m), including pheochromocytoma and isolated adrenal metastases.

Objective: To describe the clinical outcomes of patients treated by proton beam irradiation for choroidal metastatic tumors. Design: Noncomparative case series. Participants: A retrospective chart review was performed on a series of 63 patients (76 eyes) with choroidal metastases treated with proton beam therapy between December 1989 and September 2000. methods:Patients were treated with 2 fractions of 14 cobalt gray equivalents (CGEs) (CGE=proton Gy x relative biological effectiveness 1.1), each using a nonoperative “ light- field” technique. Ophthalmologic follow- up was available for 46 patients (55 eyes), with a mean follow- up time of 10 months. The medical record or the Social Security Death Index was used to obtain survival status, which was available in 94% of cases. main Outcome measures: Tumor regression, recurrence, treatment associated complications, and visual acuity were evaluated by ophthalmologic examination and ultrasonography. Eye retention and length of survival also were assessed. Results: At the time of ocular diagnosis,49 patients reported a history of a primary cancer. median survival time after ocular diagnosis was 16 months through may 2003. most choroidal metastases were dome shaped (62% ) and located at the posterior pole (95% ). mean tumor height was approximately 3.5 mm, and serous retinal detachment was seen in 63% of cases. Eighty- four percent of treated tumors regressed completely with in 5 months of treatment, and none of these recurred. Retinal detachment resolved in 82% of patients within 3.8 months after treatment, and visual acuity was preserved or improved in 47% of the patients. Complications occurred in 56% of cases and included madarosis, keratitis, dry eye syndrome, cataract, neovascular glaucoma, chorioretinal atrophy, radiation papillopathy, and radiation maculopathy. None of the treated eyes required enucleation. Conclusions: Proton beam irradiation is a useful therapeutic approach for choroidal metastases; it allows ret
