Application of DC component to select fault branch in arc suppression coil grounding system

When single phase earth fault occurs in the arc suppression coil grounding system, the amplitude of the transient capacitance current is high and decays fast, but the attenuation of the transient inductance current is much slower. This paper analyses the DC component of fault branch, and has found it is much bigger than that of the normal branches in transient state. All the simulation results obtained from three compensation types, different fault time and different wave cycles show that the DC component of fault branch is much higher than that of those normal branches. These results verify the effectiveness of taking the DC component as the method of fault line selection in the arc suppression coil grounding system.

Effect of pile-soil-structure interaction on the cable-stayed bridge in response to the earthquake

In this thesis, based on the design of a 140＋90m span unusual single tower and single cable plane cable-stayed bridge, fi＇ee vibration characteristics and seismic response are investigated; three dimensional finite element models of a single tower cable-stayed bridge with and without the pile-soil-strucW.re interaction are established respectively by utilizing finite element software MIDAS/CIVIL, seismic response of Response spectrum and Earthquake schedule are analyzed respectively and compared. By the comparison of the data analysis, for small stiffness span cable-stayed bridge, the pile-soil-structure interaction can not be ignored with calculation and analysis of seismic response.

Performance Analysis of Battery Based Stand-Alone Solar Home Systems in Malawi

Battery based standalone SHS （solar home systems） are installed in Malawi to expedite rural electrification. A study was conducted to analyze the performance of SHS in low and high insolation areas of Malawi. It is found that if the system is designed in accordance to procedures stipulated in Malawi standards, then it is capable of operating annually with mean performance ratio of 0.68, PV array production factor of 0.88 and system efficiency of 78% indicating a good system performance. The system is more reliable in high insulation areas （loss of load probability = 0.09） and when the battery charging is given priority during daytime, the overall system＇s reliability is improved by 40%. However, if the system is under-designed its performance ratio is reduced considerably and the system becomes less reliable. In overall, SHS in Malawi perform reliably if the system is well designed and maintained.

Impacts of Part-time Farming on Agricultural Land Use in Ecologically-vulnerable Areas in North China

Part-time farming has been increasing steadily in China. It is currently the largest segment among all the farm sectors in the country. Based on rural household survey data in Taipusi County as a case site ofecologically-vulnerable areas in North China, we firstly classify farm households into four types according to the proportion of non-farm income in total income, and then compare their agricultural land use patterns to empirically examine the impacts of part-time farming on agricultural land use in this area. The results suggest that non-farming households rent out all their land and give up farming, and this satisfies the expectation of other households to expand land area. The crop planting structure was not significantly different among the households, which reflected the farmers＇ will to pursuit labor productivity. Part-time farming households invest more capital and materials than full-time faming households because the income derived from non-farm employment relaxes the financial constraint of households. However, the amount of labor input of part-time farming households tends to be less, and farming practices are dominated by the elderly, female and laborers withrelative low educations.Yields of crops and the benefit of agricultural land use incline to reduce, which suggest that the potential of land use productivity is more elastic to labor inputs than capital inputs in the study area.

Cdk phosphorylation licenses Kif4A chromosome localization required for early mitotic progression

The chromokinesin Kif4A controls proper chromosome condensation, congression/alignment, and cytokinesis to ensure faithful genetic inheritance. Here, we report that Cdk phosphorylation of human Kif4A at T1161 licenses Kif4A chromosomal localization, which, in turn, controls Kif4A early mitotic function. Phosphorylated Kif4A （Kif4A^WT） or Cdk phospho-mimetic Kif4A mutant （Kif4A^TE） associated with chromosomes and condensin I （non-SMC subunit CAP-G and core subunit SMC2） to regulate chromosome condensation, spindle morphology, and chromosome congression/alignment in early mitosis. In contrast, Cdk non-phosphorylatable Kif4A mutant （Kif4A^TA） could neither localize on chromosomes nor associate with CAP-G and SMC2. Furthermore, Kif4A^TA could not rescue defective chromosome condensation, spindle morphology, or chromosome congression/alignment in cells depleted of endogenous Kif4A, which activated a mitotic checkpoint and delayed early mitotic progression. However, targeting Kif4A^TA to chromosomes by fusion of Kif4A^TA with Histone H1 resulted in restoration of chromosome and spindle functions of Kif4A, similar to Kif4A^WT and Kif4A^TE, in cells depleted of endogenous Kif4A. Thus, our results demonstrate that Cdk phosphorylation-licensed chromosomal localization of Kif4A plays a critical role in regulating early mitotic functions of Kif4A that are important for early mitotic progression.

Dynamic Changes of the Bush Encroachment in Low Altitude Area of Ethiopia

Bush encroachment is widely distributed in arid and semi-arid regions, and it has a serious impact on livestock production, especially in Africa where livestock is a primary source for the livelihoods of many people. In this study, methods of supervised classification and decision tree classification, and indexes of a land use change significance index（Ci） and a single land use dynamic degree, were applied to remote sensing imagery of Ethiopia for 1986–2016. The results show the dynamic characteristics of grassland bush encroachment in low altitude areas（pastures 1500 m above sea level） of Ethiopia in the 30 year period studied. The results revealed several interesting features of this phenomenon.（1） The area of bush encroachment showed an increasing trend, with a maximum of 3.74×10^3 km^2 in 2003, which represented 68.97% of the total area, and declined slightly from 2003~2016.（2） Among classification types, the area of severe shrub grassland was the largest, accounting for 28.36–49.10% of the total area, while the area of moderate bush encroachment accounted for 9.77–16.68%, and slight bush encroachment accounted for 5.52–7.57%.（3） The expansion rate of shrubby grassland was 0.74% for the 30 year period, while the average annual expansion rate was 2.16% for the 8 years from 1995–2003.（4） Forest land and grassland were the two main land use types of shrub grassland transformation in low altitude areas and bush encroachment changed large amounts of forest land into grassland due to shrub grassland management. The results of this study provide basic data for revealing the impacts of development processes on subsequent bush encroachment and can inform better management for the sustainable development of grasslands in low altitude systems.

Methods and application of using detrital zircons to trace the provenance of loess

The composition of single-grain detrital zircons is an effective provenance indicator of loess,and sheds new light on dust formation and transportation.Here we review the features of detrital zircons and their use as a provenance indicator,including internal structure,trace element,U-Pb age spectrum and Hf isotopic compositions,and present a case study from the Horqin sandy land and its surrounding loess.The loess samples have detrital zircon age peaks in range of 2600-2300,2100-1600,and 600-100 Ma,of which the 2600-2300 Ma zircon grains mainly have positive Hf(t) values(3.4-8.7),the 2100-1600 Ma zircon grains mainly have negative Hf(t) values(10.1-6.8),and the 600-100 Ma zircon grains have a variable Hf(t) values ranging from 21 to 15.9.The detrital zircon signatures of the loess are similar to the Horqin sandy land,but clearly different from the Chinese Loess Plateau and central-western deserts,implying that the loess is transported mainly from the Horqin sandy land in the Last Glacial period.Comparing these with neighboring tectonic units,we found that zircon populations at 2600-2300,2100-1600,and 600-100 Ma with negative Hf(t) values may come from the northeast North China Craton(NCC),and those at 600-100 Ma with positive Hf(t) values may come from the east Central Asian Orogenic Belt(CAOB).It is estimated that the two sources contribute equally to the Horqin sandy land and the surrounding loess.
