It first introduces the historical background of dams built along the Colorado River-the most important river in the West, especially the construction of Hoover Dam and Glen Canyon Dam. Then, the criticism of dams on the Colorado is examined with the emphasis on the anti-dam movement resulting from the awareness of the negative ecological impacts on the Colorado. In the conclusion, the author demonstrates the unparallel historical significance of the anti-dam movement in the environmentalism in developing the American West.展开更多

Methods: 16 women with appropriate for gestational age (AGA) fetuses and 16 women with small for gestational age (SGA) fetuses were recruited. MCA PI during “no movement” state was compared with MCA PI values during fetal body movements and breathing movements. Results: MCA PI measurements with body or breathing movements were significantly (p 0.005) lower as compared to that observed without movements. MCA PI started rising immediately after cessation of body movements and/or breathing movements. Conclusions: MCA PI with fetal body or breathing movements is significantly lower as compared to that observed in the quiet state. If MCA PI measurement is below 5th centile, it should be measured again up to 90 seconds after cessation of fetal body and/or breathing movements in order to minimize false positive diagnosis of cerebral sparing effect in SGA as well as AGA fetuses.展开更多

As exemplified by the Zhangjiakou-West Beijing region, this paper describes the intensive mantle-crust uplift, which led to anomalous element background values for regional rocks (ores) and soils. As a result, some agricultural crops, and forests and fruits are of “super-quality and high yield” or of “poor quality and low yield”. The anomalous elements can find their way into grains, fruits, vegetables and drinking water and then will be taken by human beings, constituting a food chain, which would directly impact human health and lead to the spread of some endemic diseases. Studies have shown that the geomorphological features in the Zhangjiakou-West Beijing region are the outcome of geotectonic evolution since the Mesozoic. Mantle-crust movement is the key factor leading to the evolution and change of the regionally geological environment.展开更多

No noticeabledifference was found in comparison with the control group administered with Tabella Domperidoni (P】0. 05). After the treatment, the patients’ integral value of symptoms was remarkably decreased (P【0. 01 ), and gastrokinesographic recording was evidently improved. The therapeutical effect ofacupuncture was superior or similar to that of the control group.展开更多

First, common types of earthquake damage to submarine cables are summarized, which include seabed displacement induced by fault movement, submarine landslides and seabed soil liquefaction, etc. The damage is similar to damage observed to buried pipelines following land earthquakes. The Hengchun earthquake of Dec. 26, 2006 is used as a case study. The M7.2 earthquake occurred in the South China Sea at 20：26 Beijing Time, and caused 14 international submarine cables to sever and break. The results show that the proposed method predicts damage similar to that observed in the Hengchun earthquake. Based on parametric studies of the influence of the water depth and the magnitude of the submarine earthquake, countermeasures to prevent damage to submarine cables are proposed.展开更多

Analyzing the status quo of land use of rural residential area, this paper points out that two main problems, namely, the low degree of land use, and the waste of land resources that are prevalent in the rural residential area. Based on the above analysis, the author states that the emphasis on land use will be the plain regions in the future, and adoption of reasonable economic measures will be the new solution to the problems.展开更多

The results of instant and long term therapeutic effects show that the scalp acupuncture with movement is a simple and effective skill. The instant therapeutic effects: the headache in 163 cases disappeared; in 9 cases the effect was quite obvious; and in 7 cases it was effective; the total effective rate amounted to 98.9%. The long term therapeutic effects: 135 cases (74.6%) were cured. The toral effective rate was 77.2%.展开更多

The mechanical influence of the moving charged body on a motionless one is defined in the experimental laws of electrodynamics. These laws determine the changes of parameters of the light source that moves relatively the receiver. The laws of change of light frequency and its direction of the moving source are derived from the laws of electromagnetism. At small velocity of source movement they coincide with classical results: the Doppler effect and phenomenon of aberration. The interaction of the source and receiver depends only on their velocity of movement relatively each other. There is no world medium, the relative movement to which would influence the characteristics of light source.展开更多

Parametric analyses including the degree of inclination and the distance between soil and pile are carried out herein. When the displacement of soil on the left side and right side of a pile is identical, deformation of a vertical pile and an inclined pile is highly close in both cases of surcharge load and uniform soil movement. When the couple effect of soil displacement and axial load occurs, settlement of an inclined pile is greater than that of a vertical pile under the same axial load, and bearing capacity of an inclined pile is smaller than that of a vertical pile. This is quite different from the case when the inclined pile is not affected by soil displacement. For inclined piles, P-Δ effect of axial load would lead to a large increase in bending moment, however, for the vertical pile, P-Δ effect of axial load can be neglected. Although the direction of inclination of piles is reverse, deformation of piles caused by uniform soil movement is totally the same. For the inclined piles discussed herein, bending moment(-8 m to-17 m under the ground) relies heavily on uniform soil movement and does not change during the process of applying axial load. When the thickness of soil is less than the pile length, the greater the thickness of soil, the larger the bending moment at lower part of the inclined pile. When the thickness of soil is larger than the pile length, bending moment at lower part of the inclined pile is zero.展开更多
