Author: R. O. Ovchinnikov, A. A. Sorokin, V. P. Kovach, and W. L. Xu
Subjects: Geophysics, Earth-Surface Processes
Abstract: It is the first time that there have been Sm-Nd isotopic geochemical studies conducted into the metamorphic rocks of the Gudjal block considered as a basement protrusion of the Bureya continental massif. It has been found that biotite and garnet-amphibole schists of the Gudjal formation are characterized by strongly negative εNd(0)=–15.7…–17.2 values and Paleoproterozoic values of Nd model age of tNd(DM)=2.4–2.1 Ga. Similar isotopic parameters are also typical of gneissic biotite granodiorites: εNd(0)=–18.7, tNd(DM)=1.8 Ga. Out of orthorocks of the Gudjal block studied, the Neoproterozoic orthogneisses and orthoamphibolites of the Tulovchikha formation and the Neoproterozoic gneiss-granites of the Nyatyngran complex of the Paleoproterozoic model age may be considered as a probable substrate for melts.

Abstract: The effects of cyclic stress on the polarization curve of SAC305 lead-free solder are investigated. It is found that stress increases the corrosion tendency of the material. The cyclic loading affects the corrosion current density response, which is manifested by the instantaneous surge of stress-induced current density. The cyclic stress with peak stress above yield strength significantly increases the stress-induced current density and promotes the occurrence of corrosion events. Furthermore, the effect of strain accumulation on passive film is in situ characterized by real-time observation and digital image correlation (DIC) technique, which provides effective evidence for failure.

Abstract: The occurrence and progression of hepatocellular carcinoma (HCC) is a multi-step complex process and the exact molecular mechanisms remain to be elucidated. LncRNA NEAT1 is involved in tumorigenesis and progression. However, the role of LncRNA NEAT1 in HCC remains unclear.The tumor tissues and adjacent tissues of HCC patients were collected and LncRNA NEAT1 expression was detected by Real time PCR. The hepatoma cell line HepG2 was cultured and transfected with lnc RNA NEAT1 siRNA or lnc RNA NEAT1 plasmid followed by analysis of LncRNA NEAT1 expression, cell proliferation by MTT assay, as well as Caspase 3 activity. In addition, cell apoptosis and cell cycle were assessed by flow cytometry and cell invasion was measured by transwell chambers. The expression of EGFR, Bax and Bcl-2 was detected by Western blot.LncRNA NEAT1 expression was significantly increased in HCC tissues compared with adjacent tissues (p0.05). Compared with the siRNA group, transfection of lncRNA NEAT1 siRNA into HepG2 cells significantly inhibited cell proliferation, increased Caspase 3 activity and apoptosis, reduced cell invasion, as well as arrested cell cycle (p0.05). Meanwhile, lncRNA NEAT1 siRNA also significantly decreased Bcl-2 and EGFR expression and increased Bax expression (p0.05). Transfection of lncRNA NEAT1 plasmid in hepatoma cells HepG2 reversed the above changes, compared with vector group, the differences were statistically significant (p0.05).LncRNA NEAT1 expression is increased in liver cancer tissues. Down-regulation of LncRNA NEAT1 can inhibit EGFR expression and promote hepatoma cell apoptosis, inhibit cell cycle, thus inhibiting tumor proliferation and invasion.

Abstract: The degree of tree-crop competition for nitrogen (N) and its effect on fertilizer-use efficiency and N movement were examined in a jujube tree (Zizyphus jujuba Mill.)/wheat (Triticum aestivum Linn.) agroforestry system during 2011–2012. Assessment of competition was accomplished via the installation of an experiment with five imbedding depths (20, 40, 80, 120 and 200 cm) of 15N-enriched CO(NH2)2 and two configuration patterns (sole and intercropped treatment). The percentage of N derived from fertilizer (NDFF) and fertilizer-use efficiency (UFN) were determined using 15N-enriched CO(NH2)2 (5.22% atom enrichment) applied at 8 g N per plant. Land equivalent ratios of the jujube/wheat intercropping system reached maximum ratios of 1.45 for grain (fruit) yield and 1.67 for biomass in 2011 and 1.38 for grain (fruit) yield and 1.59 for biomass in 2012. The alley cropping yield decreased significantly compared to sole-cropped plants in both years, as did the biomass of intercropped wheat in 2012. This study showed a significant difference in nitrogen acquisition between intercropping and the expected value for the various depths in both years. The %NDFF of the two plants showed significant differences between intercropping and the expected value at various depths in both years, and the intercropped %NDFF was higher than the expected value. The total UFN data, which represented an increase in response to intercropping, indicate that plants in the intercropping treatment had a higher UFN than the expected value. The UFN for jujube trees in all treatments was lower than that for wheat, indicating less uptake and utilization of N fertilizer. Management interventions, particularly those that increase fertilizer in the shallow layer may be critical for the success of this system.

Abstract: Planting trees near crops can diversify the landscape, provide pollinators for crops, and allow predators to control insect pests. However, trees can also compete with crops for light, water, and nutrients. Field experiment at the Shihezi Oasis in northern Xinjiang Province assessed the effects of distance on photosynthetic characteristics and yield of wheat in a jujube tree (Zizyphus jujuba Mill.)/wheat (Triticum aestivum L.) agroforestry system. The experiment used two treatments: a control of sole-cropped wheat (D0) and a jujube tree/wheat agroforestry system. The agroforestry system included the different distances of 90, 110, and 130 cm (D1, D2, and D3, respectively) between the wheat and the jujube trees. Photosynthetic characteristics, leaf area index (LAI), the number of stems, and yield components of wheat were determined. The net photosynthetic rate (Pn) and the stomatal conductance (Gs) of the D0, D2, and D3 during the filling stage were significantly higher than the D1. No significant difference in transpiration rate (Tr) and intercellular CO2 concentration (Ci) was noted between sole-cropped wheat and agroforestry system. From the tillering to ripening stages, significant differences were observed in stem, tiller number, and dry matter accumulation per plant, and in LAI, which ranked D0 > D3 > D2 > D1. D0 and D3 plants had significantly higher numbers of spikes, grains per spike, and weight of thousand grains than D1 and D2 plants. The crop yield was ranked as D0 > D3 > D2 > D1, with significant differences among D0, D1, D2, and D3. In conclusion, wheat yield increased as the distance from jujube trees increased in this jujube tree/wheat intercropping system.

Abstract: Effects of tree shading on crops within an agroforestry system in Hetian oasis regions in northwestern China are poorly understood. Measurements of light intensity, light use efficiency (LUE), light extinction coefficient, leaf area index (LAI), crop yield and biomass were studied in determining the effects of tree shading on crop yield in a jujube (Zizyphus jujuba Mill.)/wheat (Triticum aestivum L.) intercropping system. The treatments comprised (1) sole-cropped wheat, (2) 6-year-old sole jujube trees, (3) 8-year-old sole jujube trees, (4) 10-year-old sole jujube trees, (5) intercropping of wheat/6-year-old jujube trees, (6) intercropping of wheat/8-year-old jujube trees and (7) intercropping of wheat/10-year-old jujube trees. We found that the land equivalent ratios (LERs) of all three jujube tree/wheat treatments were larger than one and this indicated that plant growth factors were used more efficiently by the intercrop than by sole crops and the land use advantages of the intercropping systems were significantly greater than monoculture crops. Because of shading by trees, there was a decrease in intercropped wheat LAI, growth and yield, and the fruit yield of the intercropped jujube trees also decreased to a certain degree. The light interception of intercropped wheat was significantly decreased by different tree ages up to a certain point. The LUE results ranged from 1.68 to 1.31 and 1.13 g DM MJ [photosynthetically active radiation (PAR)]−1, indicating that LUE can be significantly affected by increasing tree age. Compared to intercropping 8-year-old jujube trees, a higher light extinction coefficient was found in intercropping 6- and 10-year-old jujube trees.

Abstract: A field study was conducted at Hetian oasis, southern Xinjiang, northwestern China, to investigate root distribution and morphology affected by interspecific interactions between jujube trees (Ziziphus jujuba Mill.) and cotton plants (Gossypium hirsutum L.). The treatments comprised (1) sole cotton, (2) 5-year-old sole jujube trees, (3) 7-year-old sole jujube trees, (4) 9-year-old sole jujube trees, (5) intercropping of cotton/5- year-old jujube trees, (6) intercropping of cotton/7-year-old jujube trees, and (7) intercropping of cotton/9-year-old jujube trees. Roots in each plot were sampled vertically by auger to a depth of 100 cm at 20-cm intervals and horizontally up to 150 cm away from the base of the trees at 30-cm intervals. The results showed that all jujube/cotton intercropping systems exhibited advantages of intercropping, with a land equivalent ratio > 1. The roots of both intercropped cotton and jujube had lower root length density (RLD) and root diameter (RD) at all soil depths compared with those of sole-cropped cotton and jujube trees. Interspecific competition with jujube trees altered the root development and morphology of the cotton plants. The roots of the trees spread underneath the crop and the roots of intercropped cotton tended to have a shallower distribution in the soil profile. A greater distance from the trees resulted in less influence on the RLD and RD of intercropped cotton. Older jujube trees had more developed roots and consequently higher RLD and RD. These findings may partly explain the interspecific competition effects in jujube tree/cotton agroforestry systems. However, the mechanisms underlying the root interactions between cotton and jujube require further investigation.

Abstract: The objective of this experiment was to learn more about root morphology and spatial distribution in a specify walnut (Juglans regia L.)/wheat (Triticum aestivum L.) intercropping system. The effects of intercropping on aboveground yield and land equivalent ratio (LER) were also determined. The experiment was conducted at Hetian in the southern part of the Xinjiang Uyghur Autonomous Region. The results showed that walnut/wheat intercropping reduced the aboveground yield of both component species. However, the LER of the intercropping system averaged 1.62. This meant that intercropping increased land use efficiency. Intercropping significantly reduced the root length density, root surface area density, and root diameter (RD) of both component species compared with sole-cropping. In contrast, intercropping significantly increased the specific root length of walnut. Root competition between species was the greatest in the 0–40 cm soil depth. Root competition caused uneven distribution of RD and specific root length. The plasticity of root morphology and spatial distribution is key for adapting to competition and maximizing water and nutrient uptake in walnut/wheat agroforestry systems.

Abstract: By introducing the concept of forming springback anti-coupled systems and considering the influence of the self damping effect, meanwhile establishing higher-order geometrical nonlinear equation of a high strength and low alloy (HSLA) steel plate, then a set of nonlinear dynamic springback governing equations of the plate are obtained. The finite difference method, Newmark method and iterative method are applied to solve the whole problem. Numerical results denote that the boundary conditions, thickness-length ratio of the plate and initial impact velocity of the impactor have great influence on the springback amount of the rectangular HSLA steel plate, besides the natural frequency is affected a lot by the boundary conditions and thickness-length ratio. The effect of higher-order geometrical nonlinearity on the springback amount of the plate can be ignored, considering the first-order geometrical nonlinearity is enough accurate for such similar nonlinear dynamic problems.

Abstract: The jujube tree (Zizyphus jujuba Mill.)/wheat (Triticum aestivum L.) agroforestry system is frequently used in China’s Xinjiang Province. The system improves land-use efficiency and increases economic returns. A field experiment was conducted at the Hetian oasis in southern Xinjiang Province to investigate the relationship between root distribution and interspecific interaction between the two intercropped species. The study included seven treatments: sole-cropped 5, 7, or 9-year-old jujube trees (treatments 1–3); 5, 7, or 9-year-old jujube trees intercropped with wheat (treatments 4–6); and sole-cropped wheat (treatment 7). To determine vertical root distribution, soil cores were collected in 20-cm increments from the 0 to 100-cm soil depth. The cores were collected at horizontal distances of 30, 60, 90, 120, and 150 cm from the jujube rows. The results showed that the land equivalent ratios were >1 for the three jujube/wheat intercropping systems. This indicated that these systems were advantageous compared with sole cropping. Tree height, breast height diameter, and mean crown radius were less in the intercropped treatments than in the corresponding sole-cropped treatments. Intercropping reduced the root length densities (RLDs) and root diameters (RDs) of both jujube and wheat at all soil depths. The RLD and RD of 9-year-old jujube trees were greater than those of the 5- and 7-year-old trees, which indicated that the root systems of the 9-year-old trees were more developed. Wheat root growth was inhibited more by older jujube trees than by younger ones. In conclusion, jujube tree/wheat intercropping can be practical and beneficial in the region. However, the mechanisms involved in the belowground interspecific interactions are still unknown. Additional research is needed to provide optimal management strategies and technologies for jujube/wheat intercropping.

Abstract: A field study was conducted at Hetian, southern Xinjiang, northwest China, to investigate root morphology as affected by interspecific interactions between jujube (Ziziphus jujuba Mill.) and wheat (Triticum aestivum L.). The treatments comprised (1) sole wheat, (2) 3-, 5- and 7-year-old sole jujube trees, and (3) intercropping of wheat/3-, 5- and 7-year-old jujube trees. Roots were sampled by auger in each plot down to 100 cm depth at 20 cm intervals in the soil profile and horizontally up to 150 cm away from the base of the trees at 30 cm intervals. All jujube/wheat intercropping systems had advantages of intercropping with a land equivalent ratio (LER) >1. There were significant differences in the contours of both root length density (RLD) and root diameter (RD) in intercropped wheat and jujube in the vertical and horizontal direction at corresponding soil depths but the RLD and RD of the 7-year-old jujube/wheat intercropping system were less influenced by intercropping in this respect than 3- and 5-year-old jujube intercropped with wheat. The roots of both intercropped wheat and jujube had smaller RLD, RD and larger specific root lengths (SRLs) at corresponding soil depths than did sole wheat and jujube. The older the jujube the larger were the SRL values of intercropped wheat and the smaller the RLD and RD of intercropped wheat. The greater the distance from the jujube the less influence there was on the RLD, SRL and RD of intercropped wheat and jujube and the greater the distance from the jujube the smaller was the SRL of intercropped wheat and the greater the RLD and RD of intercropped wheat (but still less than the monoculture wheat). The older the jujube the more developed were the jujube roots so that the smaller the SRL of jujube the bigger the RLD and RD of jujube. Jujube tree roots showed a mainly downward trend and extended laterally 150 cm from the trees resulting in the roots of the jujube trees and the wheat having niche overlap at a soil depth of 20–40 cm. The mechanisms underlying the thinner roots of wheat and jujube require further investigation.

Abstract: Even though agronomists have considered the spatial root distribution of plants to be important for interspecific interactions in agricultural intercropping, few experimental studies have quantified patterns of root distribution and their impacts on interspecific interactions in agroforestry systems. A field experiment was conducted to investigate the relationship between root distribution and interspecific interactions between intercropped jujube tree (Zizyphus jujuba Mill.) and wheat (Triticum aestivum Linn.) in Hetian, south Xinjiang province, northwest China. Roots were sampled by auger in 2-, 4- and 6-year-old jujube tree/wheat intercropping and in sole wheat and 2-, 4- and 6-year-old sole jujube down to 100 cm depth in the soil profile. The roots of both intercropped wheat and jujube had less root length density (RLD) at all soil depths than those of sole wheat and jujube trees. The RLD of 6-year-old jujube intercropped with wheat at different soil depths was influenced by intercropping to a smaller extent than in other jujube/wheat intercropping combinations. 6-year-old jujube exhibited a stronger negative effect on the productivity of wheat than did 2- or 4-year-old jujube and there was less effect on productivity of jujube in the 6-year-old system than in the 2- or 4-year-old jujube trees grown in monoculture. These findings may partly explain the interspecific competition effects in jujube tree/wheat agroforestry systems.

Abstract: To develop an in vitro model under conditions that highly resemble the in vivo situation for searching new therapeutics targeting invasive glioma cells.We generated organotypic brain slice "co-cultures" (OBSC) from mice and cultured the models on Millicell-CM membrane inserts. U251MG glioma cells expressing enhanced green fluorescent protein (EGFP) were established. After cultured the glioma cells to form spheroids, we implanted the spheroids onto brain slice surface. Then we evaluated the invasion area and cell density after U251MG cells were treated with the Na+-K+-2Cl- cotransporter 1 (NKCC1) inhibitor bumetanide by confocal laser microscopy.In the models, the organotypic morphology and neuronal viability were well preserved. The confocal results showed that the cell spheroid area and density of U251MG cells in bumetanide group were decreased compared to the control group in brain slices. Meanwhile, the phospho-NKCC1(p-NKCC1) protein level of U251MG cells in bumetanide-treated group was also lower than the control group.The OBSC model is a reliable and easy-to-perform in vitro method to quantify the glioma invasion ability.

Abstract: We study tools for checking the validity of a parametric regression model. When the dimension of the regressors is large, many of the existing tests face the curse of dimensionality or require some ordering of the data. Our tests are based on the residual empirical process marked by proper functions of the regressors. They are able to detect local alternatives converging to the null at parametric rates. Parametric and nonparametric alternatives are considered. In the latter case, through a proper principal component decomposition, we are able to derive smooth directional tests which are asymptotically distribution-free under the null model. The new tests take into account precisely the 'geometry of the model'. A simulation study is carried through and an application to a real dataset is illustrated.

Abstract: Laser surface treatment of aluminium alloy 6013 was conducted with the aim of improving the alloy’s resistance to pitting corrosion fatigue. The study showed that laser melting using a high power Nd:YAG laser increased the resistance of the alloy to pitting corrosion and pitting corrosion fatigue. As corrosion pits are favourable sites for the initiation of fatigue cracks, and the process of crack initiation often takes up most of the fatigue life, especially at low stress levels, a high pitting corrosion resistance resulted from the laser treatment improved fatigue crack initiation resistance. With regard to fatigue crack propagation, although interdendritic boundaries are vulnerable to corrosion attacks due to the presence of second phase particles, nonetheless, due to the nature of the rough and undulating fracture surface, fatigue growth would be retarded. Under the present experimental conditions, the improvement in corrosion resistance brought about by laser surface melting was found to prevail over the adverse effect caused by the residual stresses induced by laser melting.

Abstract: Controlling welding hot cracking based on electromagnetic force was carried out. The results show that the welding cracking can be inhibited with this method, which lies on the voltage of capacitor and the frequency of applying force. The sheet bears the downward axial force and the less radial force of flat spiral coil. The radial force points at the centre of the sheet, so it is able to compress the weld metal. Moreover, the axial force also has the ability to compress the weld metal by means of the backing plate under weldment. Controlling welding hot cracking is mainly due to the improving of mechanical condition of weld metal within brittle temperature range.

Abstract: Excimer laser surface melting (LSM) was conducted on aluminium alloy 6013 with the aim of ascertaining the significance of the laser formed nitride/oxide film in providing a corrosion barrier to the alloy. Laser surface melting was performed under two different gas environments, nitrogen and air. After the laser treatment, a compact AlN and Al2O3 mixed film was formed at the top surface of the N2 treated specimens, while only Al2O3 phase was found in the film of the air treated specimens. The laser formed film of some specimens was removed using ion etching, and their corrosion behaviour was studied. The potentiodynamic polarisation measurements showed that without ion etching, the corrosion current densities of the N2 treated and the air treated specimens were three orders and one order of magnitude respectively, lower than that of the untreated parent alloy. After ion etching, the corrosion current densities of the laser treated specimens were considerably increased. The time dependence of the ...

Abstract: We study the dark current of the GaAs/AlGaAs quantum-well infrared photodetector (QWIP) by assuming a drift-diffusion carrier transport in the barriers where the electric fields are obtained by the current continuity condition and the self-consistent energy band structure. It has been shown that due to the current continuity condition, the dark currents across the QWIP devices are determined by the thermionic emission from the emitter to the multiple quantum well (MQW) region. The self-consistent calculation of the Schrodinger and Poisson equations shows a weak electric field in the barrier region connecting to the emitter (much smaller than the average field across the QWIP at low bias) due to the accumulation of carriers in the triangle quantum well formed at the emitter-MQW interface, which results in a very small dark current at low bias. The numerical results explain well our experimental observation.

Abstract: A theoretical and experimental study of a flow-by packed bed electrochemical reactor consisting of graphite particles is given. The mathematical model describes the two dimensional distributions of electrode potential and reactant concentration in the reactor, and includes the influence of lateral dispersion between the feeder electrode and membrane. A new efficient numerical method, based on central finite difference and orthogonal collocation is used to solve the model. Results of the model simulations agree well with experimental measurement of the potential distribution for the ferrocyanide/ferricyanide system.

Abstract: Early-season populations of the cotton aphid Aphis gossypii, its ectoparasite Allothrombium pulvinum, and other natural enemies (such as spiders, coccinellids, aphidiids and syrphids) were surveyed in 7 cotton fields with different insecticide uses and cultural practices in Sheyang County, Jiangsu, China in 1991. A. pulvinum was the most abundant natural enemy of A. gossypii and accounted for an average of 80% of natural enemies in cotton fields. The abundance of A. pulvinum was low in flooded fields and increased with the number of years since the field has been rotated from flooded to dried conditions. A. pulvinum was also more abundant in monoculture cotton fields than in cotton-wheat intercropping fields. A. pulvinum was a major limiting factor of A. gossypii population growth early in the season when other natural enemies of A. gossypii were rare. Other natural enemies such as spiders and coccinellids increased in abundance later in the season and complemented A. pulvinum in providing successful control of early-season A. gossypii in unsprayed cotton fields. The role of A. pulvinum in integrated cotton pest control is also discussed.

A. pulvinum war der haufigste naturliche Feind der Blattlaus und macht i. M. 80% der Antagonisten in Baumwollfeldern aus. Die Dichte der Raubmilbe war niedrig in frisch gefluteten Feldern und stieg mit der auf die Flutung folgenden Zeit (d. h. mit zunehmender Trockenheit) an. A. pulvinum war haufiger in Baumwoll-Monokulturen als in Baumwolle-Weizen-Mischfeldern. Sie bildeten den Hauptbegrenzungsfaktor fur die A.-gosspii-Population in der Fruhsaison, wenn andere Antagonisten wie die Spinnen und Coccinelliden noch wenig zahlreich waren. Im Laufe der Saison nahm die Dichte der letzteren zu, wodurch ein immer starker werdender Regulationseffekt der naturlichen Abwehrkrafte zustandekam. Die Rolle von A. pulvinum im Rahmen einer integrierten Baumwoll-Laus-Bekampfung wird erortert.

Abstract: Chengdu-Kunming Railway is an important transport line on southwestern China. However, this railway's safety is often threatened by debris flows. How to effectively forecast and alarm the debris flow disasters and reduce the losses is the aim to study the prevention system in this paper. The factors to cause or influence debris flow are divided into four parts--the basin environmental factors, the basin meteoric factors, the prevention work's elements and the flood-relief work's elements, and the prevention system is made up of three models--a judgment model to assess the debris flow gully's seriousness, a forecast model to predict the debris flow's occurrence and an alarm model to evaluate the debris flow's disaster. Afterwards, a concise structure chart is worked out and verified by the field data from Chengdu-Kunming Railway. This prevention system will provide beneficial reference for the debris flow's monitoring network to be executed on Chengdu-Kunming Railway.

Author: T J, Liu, W L, Xu, W B, Sun, and Y Z, Zhang
Subjects: Oxygen, Endopeptidases, Fermentation, Streptomyces
Abstract: Effects of several parameters relating to dissolved oxygen(DO) on mutanolysin fermentation were studied. The experiment using shake flasks shows that the medium volume and shaker agitation speed affect the production of mutanolysin. At the same time, the agitation rate together with aeation rate has effects on DO in fermentor. Mutanolysin fermentation was affected by DO greatly. Oxygen is a key restricted factor in mutanolysin fermentation. It affects the metablism and physiological action of Streptomyces globisporus S186. Whatever the DO is excessive high or low, it won't benefit the mutanolysin production. If DO is super, S. globisporus S186 will grow luxuriantly but do not produce mutanolysin, while if DO is lower, the S. globisporus S186 won't grow well even not to produce mutanolysin. During the course of fermentation, the DO changed regularly. It is similar to many antibiotic fermentation and some amino acid fermentation. As S. globisporus S186 grow in exponential phase, DO begin to decrease rapidly from 6 h and get to the lowest point at 40 h or so. Subsequently mutanolysin starts to be produced. DO rises again from 90 h. The key technoloyg of oxygen control in the fermentation is to keep the DO at a suboptimum level. In order to get a high mutanolysin yield, during the culture in fermentor the agitation rate and aeration rate should be kept at 200 r/min and 1:0.8(V:V) respectively.

Abstract: Percutaneous balloon mitral valvuloplasty (PBMV) was successfully performed in 50 selected patients with mitral stenosis by using Inoue pillow-shaped balloon and Inoue technique. The average diameter of balloon used was 26.9 +/- 0.9 mm. 90% (45/50) of cases had either double or single mitral commissura split. Of the rest 5 cases, 1 had a mitral score 13 and 4 had a history of mitral valve commissurotomy. Totally they had a mean mitral valve area increase from 1.13 +/- 0.32 to 2.21 +/- 0.43 cm2, left atrial pressure decrease from 31.8 +/- 9.3 to 14.7 +/- 5.6 mmHg, left atrial diameter reduction from 44.9 +/- 7.7 to 37.4 +/- 4.9 mm, and transmitral gradient decrease from 21.7 +/- 9.8 to 4.0 +/- 5.2 mmHg. Most patients had a obvious cardiac function improvement, especially in patients with mitral score of 8 or less. 30% patients (15/50) had a mild mitral regurgitation, but relieved 3-6 months after procedure. During one year of follow up, the majority of patients (16/20) were found in a good cardiac function, mitral area and the left atrial diameter, except in 4 patients with a high mitral score of more than 10. It is suggested that for patient with lower mitral morphological score and good general health, a larger diameter balloon might be suitable for effectively improving patient's symptom, but for patients with a previous surgical mitral commissurotomy, PBMV should not be selected.

Abstract: Twenty-three cases of recurrent gliomas were reoperated upon. The indications and some factors influencing the length of survival time after reoperation were studied. It was found that reoperation is important in the management of recurrent gliomas, but strict indications must be followed with special attention to prevent CSF leakage, breaking and infection of the incision. Reoperation is not only to prolong life time but also to improve living quality. After reoperation, a comprehensive treatment is needed.

Abstract: Gentamicin sulfate sustained-release tablet remaining-floating in stomach (G-HBS) was developed based on the hydrodynamically balanced system. The dissolution rate of G-HBS was determined by rotary basket method (100 r/min, 37 +/- 0.5 degrees C, 0.1 mol/L HCl). The release characteristics of G-HBS showed basically first order kinetics with the dissolution rate constant (Kr) of 0.3992 h-1. The mean dissolution time (MDT) of G-HBS was 2.53 h-1. The density of G-HBS was found to have no significant influence on dissolution of G-BHS. The gamma-scintiphoto technique was used to examine the gastric retention time of G-HBS and GCT (gentamicin sulfate conventional tablet). It was shown that the gastric retention time of all subjects taking G-HBS under fed and fasted conditions were all over 4 h, in contrast with GCT, only 1-2 h. The stability of G-HBS was investigated and a tentative two-year expiration date was established. Spectrophotometry for the determination of gentamicin was established. The effect of G-HBS on Campylobacter pyloridis-associated chronic gastritis was examined through clinical trials.

Abstract: We report on the structural and optical properties of highly ordered porous alumina membranes (PAMs) under different annealing temperatures up to 1100°C. Clear structural transition from amorphous to γ- and then to α-Al2O3 has been demonstrated in PAMs through x-ray diffraction and micro-Raman scattering measurements. The crystallization of the PAMs under an annealing temperature above 800°C results in the appearance of two absorption structures in the transmission spectra ranging from 1500to1700cm−1 due to the formation of stable carboxylic impurities. We have presented convincing evidence that the blue photoluminescence band in PAMs originates from the coactions of the singly ionized oxygen vacancies (F+ centers) and the luminescent centers transformed from oxalic impurities.

ZnxTe with small x in the temperature range of 4.2 to 300 K and the wavenumber range of 20 to 350 cm−1 are reported. Local modes induced by Fe and Zn (196 and 173 cm−1), quasi-local modes induced by FeTe and ZnTe (56 and 54 cm−1) in CdTe and CdTe-like 2TA two-phonon absorption (72 cm−1) are observed and estimated by use of the Green's function method. The random- element-isodisplacement (REI) model is also used to calculate the two-mode-behaviors of the mixed crystals and to best fit the reflection spectra. Besides, the temperature dependences of the phonon absorptions are calculated and well explained. Absorptions- und Reflexionsspektren im fernen Infrarot werden fur Cd1−xFexTe und Cd1−xZnxTe- Mischkristalle mit kleinem x im Temperaturbereich von 4,2 bis 300 K und Wellenzahlbereich von 20 bis 350 cm−1 untersucht. Von Fe und Zn (196 und 173 cm−1) induzierte lokale Moden und quasilokale Moden von FeTe und ZnTe (56 und 54 cm−1) in CdTe und CdTe-ahnliche 2TA-Zweipho- nonenabsorption (72 cm−1) werden beobachtet und mit der Methode der Greenschen Funktionen berechnet. Das „random-element-isodisplacement” (REI)-Modell wird benutzt, um das Zwei- modenverhalten der Mischkristalle zu berechnen und die Reflexionsspektren am besten anzu- passen. Daneben werden die Temperaturabhangigkeiten der Phononenabsorptionen berechnet und gut erklart.

47. Les escaliers d’accrétion de calcite : un exemple de déformation par fracturation-cristallisation accompagnant le glissement sur les failles

Author: W. L. Xu and P. Vergely
Subjects: Geophysics, Humanities, Geology, Earth-Surface Processes
Abstract: ResumenLes escaliers d’accretion de calcite (ou stries de croissance) sont des structures typiques du glissement sur les tailles affectant les roches calcaires. Leur etude microscopique montre qu’ ils se sont formes par rupture de ponts de matiere reliant des cisaillements 1erordre de type P, accompagnee d’une dilatance de la zone de faille.La geometrie de la fracturation est dans le detail complexe et correspond a la superposition de microfractures de deuxieme ordre a valeur de fentes de traction, de cisaillements conjugues et de microstylolites. La geometrie de fracturation ainsi que sa cinematique sont en accord avec les modeles analogiques et numeriques proposes par Segall et Pollard (1980) et par Gamond (1983).Les modalites de la rupture sont celles d’une deformation de type fracturation-cristallisation (crack seal), indiquant un mouvement local par saccades multiples sur la faille, avec un deplacement lent et de faible ampleur. Ceci peut etre mis en relation avec un glissement (mode: II) de type “cr...

48. [Surgical treatment of thalamic tumors]

Author: W L, Xu
Subjects: Adult, Male, Adolescent, Thalamus, Brain Neoplasms, Humans, Female, Astrocytoma, Middle Aged, Child
Abstract: 15 cases of thalamic tumor are presented. Among them, 6 cases were diagnosed by ventriculography and angiography before 1980. Since 1981, 9 cases were diagnosed by CT scan. Operation was refused in 3 cases. Lateral ventriculo and superior sagittal sinus shunt was performed in one case. Open biopsy by craniotomy followed by ventriculo-interhemispheric fissure shunt was done in 2 cases. Partial resection of tumor in 8 cases. Total resection was achieved in one case. The choice of treatment of thalamic tumors is discussed. The author prefers direct operation for that may got some tumor tissues and could made the actual diagnosis pathologically. The quantity of tumor removed is decided according to the situation. Raised intracranial pressure must be controlled by shunt, and preventing its infection is very important.

49. Gap mode of Mn in HgTe

Author: Zhongyuan Yu, S. C. Shen, W. L. Xu, H. J. Ye, W. J. Lu, and K. J. Ma
Subjects: chemistry.chemical_classification, Lattice dynamics, Physics, business.industry, Band gap, Analytical chemistry, Gap mode, Optical reflection, Optics, chemistry, Density of states, business, Inorganic compound, Solid solution
Abstract: Un mode de bande interdite de Mn dans HgTe est observe pour la premiere fois a l'aide d'une spectroscopie de reflexion de l'infra-rouge lointain. Le mode est situe a 97 cm -1 , ce qui est au-dessus de la bande de phonon LA et dans la bande interdite de la densite des phonons des etats pour HgTe. La dependance du comportement du mode de bande interdite vis-a-vis de la concentration en Mn et la temperature est etudiee experimentalement. La dynamique du reseau de defauts est utilisee pour analyser le comportement du mode de bande interdite
