Development of the CAS-IBB single-particle microbeam for localized irradiation of living cells

A single-particle microbeam facility has been constructed at the Key Laboratory of Ion Beam Bioengineering (LIBB), Chinese Academy of Sciences (CAS). The system was designed to deliver a defined numbers of hydrogen ions, produced by a van de Graaff accelerator, in an energy range of 2.0-3.0 MeV, into an area smaller than that of the nucleus of an individual living cell. The beam is collimated by a borosilicate glass capillary that forms the beam-line exit. An integrated computer program recognizes the cells and locates them one by one over the microbeam exit for irradiation. We present technical details of the CAS-LIBB microbeam facility, particularly on the collimator, hardware, control program, as well as cell irradiation protocols available. Various factors contributing to the targeting and positioning precision are discussed along with accuracy measurement results.     

P-RC APMP PULPING OF THE TRIPLOID OF POPULUS TOMENTOSA

The technology parameters of P-RC APMP process of the triploid of populus tomentosa and the the comparison of P-RC APMP with one and two stage f pretreatment were investigated in this paper. The results showed that in the chemical pretreatment the s that affected the pulp qualities. The charge of NaOH,y in the first stage of chemical pretreatment,was related to pulp strength. The charge of H2O2 tant pulp.In addition, the ratio of NaOH to H2O2 and the on of chemicals in the first and second stage of impregnation also affected the pulp qualities. The and two-stage P-RC APMP pulp illustrated that the ulp had better brightness and breaking length, lower light scatting coefficient and opacity.     

Effect of New O-Superfamily Conotoxin on Voltage-Activated Currents of Hippocampal Neurons

The effects of a new O-superfamily conotoxin, SO3, on sodium current (INa), transient A-type potassium currents (IA), and delayed rectified potassium currents (IK), were examined in cultured rat hippocampal neurons using the whole-cell patch clamp technique. Addition of SO3 caused a concentration-dependent, rapidly developing, and reversible inhibition of voltage-activated currents. The IC50 values for the blockage of INa, IA, and IK were calculated as 0.49, 33.9, and 7.6 μmol/L, respectively. The determined Hill coefficients were 1.7, 0.6, and 1.2, respectively. These results indicate that SO3 can selectively inhibit neuronal sodium and potassium currents.     

WATER-BASED BINDERS USED IN PROCESS FORMAKING AUTOMOBLE FILTER PAPER

INTRODUTIONThe paper used as the filtration medium for automotbile filters has been traditionally treated with alcohol solution of phenolic resins. This has been done to improve the paper's strength properties and allow it to be pleated in an accordion-like shape and to hold the shape when the paper composite is cured.[1]With the onset of greater concern for environmental quality, the filter manufactures have requested paper suppliers to provide a free or lower formaldehyde-containing impr…     

BIOCHEMICAL PULPING OF REED PRETREATED BY WHITE ROT FUNGI

INTRODUCTIONThe origin of biological pulping is natural degradation of lignin by microorganism, such as white rot fungi. Many researches have been carried out, on the biological degradation of the lignin in raw materials, mostly on woods. Those researches were mainly focused on microorganism pretreatment as a prior proceeding of the mechanical pulping, for the rare possibility of pulping directly with the pretreatment by a microorganism. A series of reports showed that microorganism pretr…     

STUDY ON THE ELEMENTAL CHLORINE FREE BLEACHING OF BAMBOO KRAFT PULP

1INTRODUCTIONChina is a country using the most variety of non-wood fiber raw material and is the largest country producing non-wood fiber pulp and paper in the world[1]. Bamboo is one kind of the main non-wood species for papermaking in China. Although the structure of raw materials for papermaking has being adjusted through increasing the proportion of wood pulp and by effectively utilizing waste paper source, non-wood species will still remain an important fiber resource[1,2].At present…     

一种适用于时序InSAR的同质像元加权干涉相位滤波方法

为了有效地利用多时相InSAR的时间维度信息, 并保证滤波窗口内像元的同质性, 提出一种同质像元加权干涉相位滤波方法。首先采用拟合优度检验, 对多时相SAR 图像的同质像元进行识别, 然后在同质像元之间进行加权干涉相位滤波, 以保证中心像元在滤波过程中不受周边非同质像元干扰。基于真实干涉SAR图像的实验结果表明, 与经典Goldstein滤波及Lee滤波相比, 该滤波方法在目视效果、相位残差点数量及相位导数标准差3个指标上具有优势, 实现滤波器的设计初衷。
