The convergence of meridians toward the South Pole causes unique problems for geometrical comparison of structural geological and geophysical datasets from Antarctica. The true North reference direction ordinarily is used for measuring and reporting vector data (strike, trend) in Antarctica, as elsewhere. However, over a latitude distance of just 100 km at 85° South, the angular difference in t...

Crossing borehole is an effective means to eliminate the outburst risk of coal and gas. The influence inclination angle, diameter, drainage time on radius gas are studied by numerical simulation engineering example verification. study shows that changes in a “U” shape with increase angle. When angle α seam plane decreases, increases. Furthermore, mass around broken shear deformation, which cons...

S U M M A R Y Radial and azimuthal anisotropy in seismic wave speeds have long been observed using surface waves and are believed to be controlled by deformation within the Earth’s crust and uppermost mantle. Although radial and azimuthal anisotropy reflect important aspects of anisotropic media, few studies have tried to interpret them jointly. We describe a method of inversion that interprets...

This paper analyzes collective bargaining using Spanish firm level data. Central to the analysis are the joint determination of wage and strike outcomes in a dynamic framework and the possibility of segregate wage equation for strike and non-strike outcomes. Conditional to strikes taking place, we confirm a negative relationship between strike duration and wage changes in a dynamic context. Fur...

We analyze the magnetic equatorial component of Jupiter’s radio synchrotron radiation belts using two-dimensional images recorded by the Australia Telescope Compact Array and the Very Large Array over a period of several years, during which DE , the Earth’s declination seen from Jupiter, changed from DE = −2.9◦ to near 0◦. The brightness distribution of the belts changed markedly. When DE = −2....

Pre-existing crustal structures are known to influence rifting, but the factors controlling their remain poorly understood. We present results of digital image correlation that allows for surface strain analysis a series analog rifting experiments designed test size, orientation, depth, and geometry pre-existing weak zones on localization partitioning. apply distributed basal extension crustal-...

The lightning phenomenon is a natural disaster that endangers human life. nature of grabbing objects closest to the cloud can cause fires, damage electrical equipment, and even fatalities. Padang Institute Technology campus has tall buildings, such as buildings B, C, D, E, F, without an adequate protection system. This certainly concern regarding security safety for building users on ITP campus...

We study the problem of finding appropriate experts who are able to complete timely reviews and would not say “no” to the invitation. The problem is a central issue in many question-and-answer systems, but has received little research attention. Different from most existing studies that focus on expertise matching, we want to further predict the expert’s response: given a question, how can we f...

The research is set to examine Academic Staff Union of Universities (ASUU) strikes and academic performance of students in Ekiti State University (EKSU) Ado-Ekiti. The research employed multistage sampling technique to select the faculties and the departments from where six hundred and four (604) respondents were selected, questionnaires and interviews were employed to draw information from res...
