Complex chromosomal changes in a primary squamous carcinoma of the parotid gland

The chromosomal observations in a cultured primary epidermoid carcinoma of the parotid gland are reported. The tumour had a flat hyper-triploid mode with 7 recurrent wholly or partially identified marker types and 7-13 additional, mostly recurrent, markers, whose origin could not be clarified. There were also many recurring numerical deviations in most tumour cells. The picture was consistent with a neoplasma in an advanced stage of chromosomal progression. So far, 6q-markers with varying morphology are the only deviations found in most types of malignant salivary tumours and, in particular, in a high percentage of adenoid-cystic carcinomas. One possible explanation for these observations is the occurrence of one or more suppressor genes in 6q which may have relevance for malignant neoplasia in salivary gland tissues.

HA—微孔钛基涂层种植体的复合强度

研究了羟基磷灰石(HA)和中性玻璃(G)的混合涂料在TC4多孔钛基体上的界面复合强度。探讨了中性玻璃含量、基体表面状态以及烧结工艺对这种涂层复合种植体的复合强度的影响。指出:复合的实质是中性玻璃与基体的润湿结合,最合适的玻璃含量为50 wt%,提高复合强度的关键,在于基体表面的TiN蒸镀处理,当TiN厚度为2～3 μm时,复合强度可达7.2 MPa。最佳烧结工艺为:900～950℃/30 min。     

Evaluation of optimization operation models for cascaded hydropower reservoirs to utilize medium range forecasting inflow

This paper evaluates the performances of the models that incorporate forecasting inflow for cascaded hydropower reservoirs operation.These models are constructed separately on the concepts of explicit stochastic optimization(ESO)and implicit stochastic optimization(ISO)as well as parameterization-simulation-optimization(PSO).Firstly,the aggregation-disaggregation method is implemented in ESO models to reduce the complexity of stochastic dynamic programming(SDP).And the aggregate flow SDP(AF-SDP)and aggregation-disaggregation SDP(AD-SDP)are constructed respectively.Secondly,in ISO model,decision tree is the well-known and widespread algorithm.The algorithm C 5.0 is selected to extract the if-then-else rules for reservoir operation.Thirdly,based on the PSO model,the hedging rule curves(HRCs)are pre-defined by fusing the storage and inflow as state variable.The parameters of the HRCs are determined by using the simulation-optimization model.Finally,China’s Hun River cascade hydropower reservoirs system is taken as an example to illustrate the efficiency and reliability of the models.In addition,the values of quantitative precipitation forecasts of the global forecast system(10 days lead-time)are implemented to forecast the 10 days inflow.

GFS降雨预报图数值化处理算法在洪水预报中的应用

鉴于大部分气象系统对外发布的降雨预报信息均为降雨预报图的形式而不能直接用于水库调度,设计了一种GFS降雨预报图数值化处理算法,可计算出降雨预报图中任意像素点的降雨数值预报信息,然后利用计算出的GFS降雨数值预报信息与洪水预报模型耦合来进行洪水预报,并以桓仁水库2010年的一场洪水为例进行了验证。结果表明,利用该算法计算出的降雨数值预报信息可应用于洪水预报,具有较好的应用前景。
