Exo-glycosidases Activities in Artemisia sphaerocephala Mucilaginous Achene Germination Process

白沙蒿 (ArtemisiasphaerocephalaKrasch .)是中国西北沙区分布的多年生植物。瘦果遇湿后其粘液层开始膨胀。对其种子萌发不同阶段的种胚提取物中几种可能降解果皮外层粘液物质的外切糖苷酶进行了检测。结果表明 :β 吡喃半乳糖苷酶在干种子中的活性很高 ,但是随着种子的吸涨而逐渐降低 ,在已萌发的种子中无法探测到。α和 β 吡喃阿拉伯糖苷酶、β 吡喃葡萄糖苷酶以及 β 吡喃甘露糖苷酶在种子萌发过程的胚提取物中也显示出了一些活性 ,但是这些活性在种胚外却无法探测到。所有胚提取物中的外切糖苷酶都无法降解果皮粘液物质。所有的证据都表明果皮外层的粘液物质无法在种子萌发的早期被水解。因此果皮粘液物质在干旱沙质条件下的生态功能被限制在吸收水分以及延长胚吸水的时间。

A General Overview of the Typical 18 Frontal-VentralTransverse Cirri Oxytrichidae s. l. Genera(Ciliophora, Hypotrichia)

Oxytrichidae s. l. ciliates usually have 18 frontal-ventral-transverse cirri which are clustered to six distinct groups usu- ally originating from six longitudinal primordia segregating 1, 3, 3, 3, 4, 4 cirri. During morphogenesis, three dorsal kinetics anlagen are primarily formed. Fragmentation of kinety 3 usually present, while sometimes secondarily lost. Dorsomarginal kineties are formed, while sometimes lost. Oxytrichids tend to have overlapping characters, e.g. cell shape and size, infraciliature, pellicle fea- tures. This makes a great problem for genera separation. In the present work, all typical 18 frontal-ventral-transverse-cirri Oxytrichi- dae s. 1. genera were revised systematically based on their living morphology, ciliature patterns and dorsal morphogenetic features. The outline of the genera, the schematic illustrations, and the key to typical 18 frontal-ventral-transverse-cirri genera of Oxytrichidae s. l. were clarified. Additionally, some morphological and morphogenetic patterns were summarized and compared.

Characteristics of the May 12,2008 Wenchuan M_S8.0 Earthquake Sequence and Discussion on Relevant Problems

The aftershock activity of the May 12, 2008 Wenchuan Ms8.0 Earthquake Sequence shows an obvious segmented feature. Most of the large aftershocks were distributed in the north and south parts of the aftershock zone. Thrusting was dominant with a small amount of strike-slip component in the south part. The aftershock activity decayed gradually, presenting the sequence features of a mainshock-aftershock pattern. The north part was the ending area of the malnshock fracture where strike-slipping was dominant, showing an obvious swarm feature. Therefore it became the major area for large aftershocks. The modulation of the earth tide on aftershock activity is remarkable; most large aftershocks occur during the period of flood and neap tide. The time period around 16：00 was the dominant occurring time for large aftershocks. The p-value, a parameter of modified Omori formula, increases gradually with time, and reaches about 1 at the end. Based on previous study, the sequence patterns, magnitude of maximum aftershock, as well as the duration of aftershock activity has been discussed. The primary results also show that the magnitude difference between the maiushock and the maximum aftershock is proportional to the rupture size of the maiushock for huge earthquakes of about Ms8.0. This means that when the magnitudes of the earthquakes are nearly the same, large rupture size corresponds to sufficient energy release.

Small and Medium-Sized Enterprises （SMEs） in Personal Services

Entrepreneurship has become an attribute of the current growth without business activities. Entrepreneurship is a global world. It is not possible to think about economic driving force of technological development and scientific research. It materializes knowledge and involvement of people and society. Expansion of business activities is a source of individual country＇s economic performance. It contributes to the development of people＇s living standards. In every market economy, it represents an irreplaceable role for small and medium-sized enterprises （SMEs）. A strong representation of＂micro-enterprises＂ can be found in the field of personal services. Companies within the course of their existence go through particular stages of their development--from their foundation through the stage of steady development. After this stage, there comes their decline that can develop even into their termination. We indicate this process as a company life cycle. The aim of the submitted project is to map the life cycle of particularly chosen companies providing accommodation and catering services and to find a mutual relation among observed quantities and their stable economic positions in the market. The analysis is based on the data of macro-economic character, the data about development of receipts in the sector, development of inflation, tempo of economic growth, and development of consumer prices. Out of a company, non-financial factors will also be considered. The core of the analysis is the stage of sustainable stability of the assessed companies. The point of the findings is revelation of the causes of risks of possible transition into the stage of termination due to the decline of services volume, decline of profitability, and long-lasting payment insolvency. The contribution of the project is to draw our attention to possible risks of critical situation development and to propose how to avoid them so that the company will not occur in financial straits. Achieved information could assist the company management to make relevant decisions.

Relocation of Earthquakes in Shandong and Its Neighboring Areas,China and Its Relationship with Active Tectonics

Earthquakes taking place from 1975 to 2010 in and around Shandong Province are relocated using double-difference(HypoDD)and Hypoinvers 2000(Hypo2000)methods,after correction of the onset times of seismic phases.The results show that the relocated seismicity is clearly associated with regional tectonics in space,and is also in agreement with the existence of deep faults imaged by wide-angle and deep seismic reflection profiling;most of the focal depths are in the range of 5～25km,and there are clearly two predominant depths:10km and 16km,which are inferred to be on the bottom of the upper crust and in the middle crust,respectively.The pattern of seismic activity indicates that moderate and strong earthquakes are likely to occur in the brittle-ductile transition zone between the upper and the lower crust,as the outcome of the deep tectonic dynamic process and the movement and deformation of faults in the upper and shallow crust under the regional stress field.

Major Accumulations of Life and Main ＂Pain Points＂ in the Seas and Oceans

Because of permanent matter and energy accumulation in the sea marginal biotopes, communities of organisms adapted to these specific conditions are developed. Terms contour biotopes and contourobiont＇s communities were proposed. These habitats are populated by a great variety of organisms with numerical superiority of early stages of development of hydrobionts. Therefore, contour biotopes are responsible for the reproduction of many species of plants and animals, including commercialiy ~rnportant species of invertebrate and fish. But as a result of natural physical and chemical processes, the same habitats accumulate many substances that are harmful to living organisms, especially for early ontogenetic stages. So here formed main hotspots, critical ecological zones in seas and oceans, which need to be monitored in the first place. Understanding of the key role of contour biotopes and communities in marine ecological processes development is an ecological imperative. Making of ecological diagnoses, prediction of possible departures from the ecological norm and prevention of serious negative events in the marine environment needs special consideration of contour biotopes and their inhabitants, which are underestimated in traditional marine biological and ecological investigations.

Effect of Acupuncture on Functional Reconstruction of the Wrist Following Cerebral Apoplexy

Objective： To observe the effect of needling different points on functional reconstruction of wrist following cerebral apoplexy. Methods： Forty apoplexy cases were randomly allocated into four groups, 10 in each. Cases in group A were treated by needling the extensor muscle motor points. Cases in group B were treated by needling alternating extensor-flexor muscle motor points. Cases in group C were treated by needling Jianyu （LI 15）, Binao （LI 14）, Shousanli （LI 10） and Waiguan （TE 5）. Cases in group D were treated by needling Jianyu （LI 15）, Binao （LI 14）, Shousanli （LI 10）, Waiguan （TE 5）, Chize （LU 5） and Neiguan （PC 6）. The motor functions of affected upper limbs were evaluated on the surface electromyography （SEMG）, Fugl-Meyer function scale and Barthel ADL （Activities of Daily Living） indexes. Results： Needling alternating extensor-flexor muscle motor points can significantly increase the peak value （MAX） of the upper limb SEMQ integrated electromyogram （IEMG）, Fugl-Meyer motor function value and Barthel ADL indexes. Conclusion： Needling different points may produce different effects on wrist function following cerebral apoplexy. Needling alternating extensor-flexor muscle motor points can obtain an exact treatment effect.

Efficacy observation on Governor Vessel-regulating and brain-unblocking acupuncture for post-stroke depression

Objective： To observe the clinical effect of Governor Vessel-regulating and brain-unblocking acupuncture on post-stroke depression. Methods： A total of 70 eligible cases were randomly allocated into an observation group and a control group according to the random number table. Patients in the observation group were treated with Governor Vessel-regulating and brain-unblocking acupuncture, whereas patients in the control group were treated with oral Escitalopram Oxalate tablet. The treatment lasted for 8 weeks. The Hamilton depression scale （HAMD）, Montgomery Asberg depression rating scale （MADRS）, and Barthel index （BI） were used to evaluate the patients＇ condition before, 4 weeks and 8 weeks after treatment respectively. In addition, adverse reactions were also recorded. Results： After 4 weeks of treatment, the HAMD and MADRS scores were significantly decreased in both groups （P〈0.05）; and the BI scores were significantly increased in both groups （P〈0.05）. There was no between-group statistical difference in HAMD score （P〉0.05）; the MADRS score in the observation group was significantly lower than that in the control group （P〈0.05） and the BI score in the observation group was significantly higher than that in the control group （P〈0.05）. After 8 weeks of treatment, there were no between-group statistical differences in all aspects （P〉0.05）; however, the adverse reactions in the observation group were significantly less than those in the control group. Conclusion： The Governor Vessel-regulating and brain-unblocking acupuncture is safe and effective for post-stroke depression and can obtain similar efficacy as Escitalopram Oxalate tablet. In addition, it can fast alleviate core symptoms of depression and improve the activities of daily living （ADL） and has fewer adverse reactions.

Statistical study of magnetotail flux ropes near the lunar orbit

Flux-rope/TCR events near the magnetotail lunar orbit （-67RE 〈 GSM X＊ 〈 -39RE） were studied using magnetic-field and plasma data measured by THEMIS B and C between January 2011 and March 2012. The aberrant coordinate GSM＊, where the X＊ axis is rotated 4° relative to GSM-X, was used to count the occurrence rate. The number ratio of earthward to tailward events was about 3：5. Moreover, the event occurrence rate distribution showed a clear dawn-dusk asymmetry distribution, with dusk-side events accounting for 57.98%. A superposed epoch analysis of the flux-rope events showed that earthward events had a shorter duration in the leading than in the trailing part. Earthward events also displayed a lower temperature and a lower flow speed than tailward events. We studied the relationship between the event occurrence rate and geomagnetic activity level even further. The occurrence rate of tailward flux-rope/TCR events increases with increasing AE-index, whereas earthward events occur mainly in the relatively quiet period of geomagnetic activity （AE - 100-300 nT）. Flux-rope/TCR events identi- fied within a 10 mm time frame were treated as belonging to a single reconnection event. By comparing the occurrence rates of earthward and tailward events along X＊, we estimated the most likely location of the near-Earth reconnection site as X＊ = -36RE.

Contrast of tropical cyclone frequency in the western North Pacific between two types of La Nia events

According to the different pattern of sea surface temperature anomaly （SSTA） in the previous year of La Nifia events, we cat- egorized La Nifia events into two types to investigate the different characteristics of tropical cyclone （TC） activity over the western North Pacific （WNP） in TC peak season of two types La Nifia events. One type is following the previous El Nifio event （La Nifia I）; the other is following the previous neutral phase or developing La Nifia event （La Nifia II）. Results show that TC genesis frequency in the WNP during TC peak season of La Nifia I is less than normal year, whereas it has no differ- ences from normal year during La Nifia II. The main reason is attributed to the different amplitude SSTA in the East Indian Ocean （EIO） and the western Pacific Ocean （WPO）. Similar to the capacitor effect, strongly positive SSTA in the EIO-WPO during La Nifia I triggers an equatorial baroclinic Kelvin wave, which intensifies the easterly in the lower troposphere and weakens the East Asian summer monsoon, and thus the TC frequency decreased during La Nifia I. However, the easterly anomaly shows a weak response to the SSTA in the EIO-WPO during La Nifia II, and there is no significant change in the en- vironmental pattern over the WNP; so is TC frequency. The modulation of strong EIO-WPO SSTA on large-scale circulation over the WNP reduces the environmental barotropic energy conversion into synoptic-scale disturbances during La Nifia I, and also suppresses TC disturbances. The understanding of two different types of La Nifia events could help improve the seasonal prediction of TC activity in the WNP during La Nifia.

Upper crustal P-wave velocity structure beneath two volcanic areas in northern Iran

Detailed information about the crustal structure is essential for better understanding the occurrence and mechanisms of earthquakes and volcanoes.Here we present a study of the upper crustal P-wave velocity structure of two seismically and volcanically active areas in northern Iran using the two-dimensional Pg travel time tomography method.The imaging results suggest low velocities in the upper crust beneath the Damavand and Sahand-Sabalan volcanic areas in the central and western parts of northern Iran,respectively.The upper crustal low velocities in these two areas roughly coincide with previously imaged low Pn velocity anomalies,suggesting that the Late Cenozoic volcanic activity was probably caused by the upwelling of hot materials from the mantle.The image feature of the Pg velocity structure beneath the Sahand-Sabalan volcanic area further indicates that the hot materials stored in the upper crust beneath Sahand may be larger in size than those stored beneath Sabalan.Comparison of the Pg velocity images with the earthquake distribution in north Iran suggests that earthquakes mainly occur at moderately low velocity or low to high velocity boundary areas instead of significantly low or high velocity regions.The anisotropy results show that the Pg wave fast direction is consistent with the GPS direction at high Pg velocity areas and the fast direction is inconsistent with the GPS direction but consistent with the strike direction of faults at low velocity areas.Our new upper crustal structural images provide the basic observation for better understanding of the regional seismicity and volcanism,and link the surface geological phenomena to deep crustal and mantle processes associated with the active tectonics in northern Iran.
