For each prime number p which does not divide N there is a linear operator Tp acting on Sk(N,C), known as the p-th Hecke operator. (In fact, the Tp stabilize Sk(N,Q).) A modular form which is an eigenvector for all of these linear operators simultaneously is called an eigenform; the space Sk(N,C) has a basis made up of eigenforms, and the Fourier coefficients of these eigenforms can be normaliz...

classification and utilization of lands based on their capability are necessary for sustainable land use management. the purpose of this study was to identify and grade the effective qualities on the rainfed farming in the roin area, north khorasan province, during the year of 2011. based on field observations and literature review the land qualities including climate, rooting conditions, moist...

The revegetation of areas impacted by iron mining may be hampered a series chemical and physical impediments exhibited those areas. Physical problems, such as penetration resistance steep slopes, outweigh the that both should considered for soil recovery. This study aimed to evaluate main attributes are directly related plant growth on affected activities discussing possible solutions. For this...

Abstract Humans constitute one of the main geomorphological agents in modern times. As an example, post‐mining regions represent a typical landscape Anthropocene. Strong relief modifications are particularly obvious with open pit mining. However, many existing mining areas lacking detailed pre‐mining information for quantification anthropogenic changes, which is considerable challenge historic ...

Let X be a norm curve in the SL(2,C)-character variety of a knot exterior M . Let t = ‖β‖/‖α‖ be the ratio of the Culler-Shalen norms of two distinct non-zero classes α, β ∈ H1(∂M,Z). We demonstrate that either X has exactly two associated strict boundary slopes ±t, or else there are strict boundary slopes r1 and r2 with |r1| > t and |r2| < t. As a consequence, we show that there are strict bou...

Prospective control of walking and running requires perceiving sloping surfaces that can and cannot support these activities. Two experiments on slant perception were conducted, motivated by the notion of geographical slant rather than optical slant, and by an affordance based description of surface layout. In Experiment 1, participants standing on a horizontal surface (the ground) adjusted the...

Among hemodialysis patients, the assessment of dry weight remains a matter of clinical judgment because tests to assess dry weight have not been validated. The objective of this study was to evaluate and validate relative plasma volume (RPV) monitoring as a marker of dry weight. We performed RPV monitoring using the Crit-Line monitor at baseline and at 8 weeks in 150 patients participating in t...

Slopes are subjected to stress redistributions during underground mining activities, and this may eventually cause deformation or landslide. This paper takes Madaling landslide in Guizhou Province, China as a case study to investigate the failure mechanism and its run-out behaviours by using discrete element method. Previous qualitative analysis indicated that the slope experienced four stages ...

Taken 1:10000 Scale topographic map in the small watershed of Genxi River as an example, under the support of ARCVIEW and ARC/INFO software of GIS, through digitizing topographic map and other special maps to set up a spatial geodatabase. This paper forms a digital elevation model and has an analysis of slope and aspect, also discovered knowledge referenced for soil and water conservation. The ...
