针对既有装配式主梁铰缝连接强度弱、湿连接施工复杂等问题,充分考虑飞机荷载桥梁荷载集度大、空间受力显著等特点,提出一种剪力键和横向预应力筋混合连接的装配式主梁连接方案。该方案通过剪力键与键槽实现相邻主梁拼接,采用横向预应力筋为接缝界面提供压应力储备,具有结构整体性好、施工方便等优点。以某机场滑行道桥为对象,基于ABAQUS平台建立新型连接装配式主梁的非线性数值模型,开展静、动力学性能分析以验证方案的可靠性,揭示了剪力键位置、数量、高度及初始预应力对主梁力学行为和抗震性能的影响规律。结果表明:飞机静载作用下,该方案能够满足规范对于主梁挠度限值的要求且具有可观的安全储备。增设跨中剪力键及增加其数量可显著降低主梁跨中挠度和弯矩;相较于仅设置梁端剪力键,加设3道跨中剪力键可使静载下力学响应分别降低19.92%、23.35%,使地震下力学响应分别降低17.29%、40.12%。剪力键倾角和高度对主梁受力影响较小,增大横向预应力筋初始张拉力可有效提高主梁接缝界面的预压应力,静载、地震下的最大增幅分别为45.31%、46.51%。研究成果可为飞机荷载桥梁的主梁拼装提供重要的技术支撑,并可拓展应用于重载公路、铁路桥梁。

We report a case of primary aldosteronism caused by bilateral solitary aldosteronomas occurring 6 months apart, the diagnosis being confirmed by clinical features. Multiple aldos-terone-producing adenomas can be unilateral or bilateral. If bilateral, most of them are found simultaneously. Bilateral solitary aldosterono-mas occurring at separate times are rarely re-ported and the pathogenesis is still elusive. We believe, from this case, the postoperative fol-low-up in patients with primary aldosteronism is mandatory.

在长江上游地区的江水源热泵工程设计中,江水温度的全年变化情况是确定系统方案的重要依据之一。对长江上游水温的特点及影响因素进行了分析。以重庆世纪会江水源热泵工程、长江上游水文水资源勘测局和重庆气象站的监测数据为依据,对江水水温和气温之间的关联关系进行了多项式和非线性拟合,结果表明Boltzmann拟合模型的计算值与实测值的吻合度较好;采用长江寸滩站的实测水温对Boltzmann拟合模型进行了校验,结果表明该模型可以较好地预测不同气温情况下的江水水温,可以在重庆主城区长江河段的水源热泵工程设计中应用。

An extended π calculus was introduced to deal with secure movement and intercommunication between agents. The system extends Nomadic-π with objective migration primitive and confined region which serves as annotation labels of agents and channels. The confined region labels were used to uniquely identify the constraints on the migration and communication of agents, with the labels, the agents could be confined in a secure subsystem and the inter-agent communication could be confined between agents located on trusted sites during computation. The operational semantics for the calculus was given out, and a type system which enforces security properties called confined migration and confined communication was developed.

AIM: To evaluate the clinicopathological features and treatment outcomes of cap polyposis in the pediatric population. METHODS: All pediatric patients with histologically proven diagnosis of cap polyposis were identified from our endoscopy and histology database over a 12 year period from 2000-2012 at our tertiary pediatric center, KK Women's and Children's Hospital in Singapore. The case records of these patients were retrospectively reviewed. The demographics, clinical course, laboratory results, endoscopic and histopathological features, treatments, and outcomes were analyzed. The study protocol was approved by the hospital institutional review board. The histological slides were reviewed by a pediatric histopathologist to confirm the diagnosis of cap polyposis. RESULTS: Eleven patients were diagnosed with cap polyposis. The median patient age was 13 years (range 5-17 years); the sample included 7 males and 4 females. All of the patients presented with bloody stools. Seven patients (63%) had constipation, while 4 patients (36%) had diarrhea. All of the patients underwent colonoscopy and polypectomies (excluding 1 patient who refused polypectomy). The macroscopic findings were of polypoid lesions covered by fibrinopurulent exudates with normal intervening mucosa. The rectum was the most common involvement site (n = 9, 82%), followed by the rectosigmoid colon (n = 3, 18%). Five (45%) patients had fewer than 5 polyps, and 6 patients (65%) had multiple polyps. Histological examination of these polyps showed surface ulcerations with a cap of fibrin inflammatory exudate. Four (80%) patients with fewer than 5 polyps had complete resolution of symptoms following the polypectomy. One patient who did not consent to the polypectomy had resolution of symptoms after being treated with sulphasalazine. All 6 patients with multiple polyps experienced recurrence of bloody stools on follow-up (mean = 28 mo). CONCLUSION: Cap polyposis is a rare and underrecognised cause of rectal b

AIM: To investigate the relationship between single nucleotide polymorphisms in the uridine-diphosphoglucurono-syltransferase (UGT) UGT1A7 and UGT1A1 genes and patients suffering from colorectal cancer (CRC). METHODS: A case-control study was designed in order to investigate the genotypes of the UGT1A7 and UGT1A1 genes, which were identified by the polymerase chain reaction-restriction fragment length polymorphism (RFLP) method, for 268 CRC patients and 441 healthy controls. RESULTS: The results of simple logistical regressions revealed odds ratios (ORs) of 1.97 (Pongst patients [observed OR (6.83) greater than expected OR (4.56)]. CONCLUSION: In conclusion, carriage of the UGT1A7*3 allele, as well as variant-211 UGT1A1 allele represents a risk factor for the development of, and a determinant for, metastases associated with CRC patients.
