We prove that the existence of a slightly massive gravitino or gaugino in a class of Gaussian string compactifications, implies the existence of an entire tower of such states below Mplanck, signaling the approach to a limit of decompactification.

OBJECTIVES The purpose of this study was to evaluate to which degree investment of acquisition time in more encoding directions leads to better image quality (IQ) and what influence the number of encoding directions and the choice of b-values have on renal diffusion tensor imaging (DTI) parameters. MATERIAL AND METHODS Eight healthy volunteers (32.3 y ± 5.1 y) consented to an examination in a...

Salt stress is one of the major factors limiting crop productivity worldwide. Grain amaranth is new crop with high yield potential and good nutrition value which can be a good substitute for salt-sensitive crops in saline areas. This research was conducted to evaluate different level of salinity and applied salinity stress at several growth stages on some morphological and physiological traits ...

sesame could be an appropriate oilseed crop for water limited environments. this research was aimed at studying growth, leaf chlorophyll fluorescence, proline content, yield and yield components of sesame cultivars under different moisture regimes. a 4-replicate split plot rcbd field experiment was conducted at the lavark research farm, college of agriculture, isfahan university of technology, ...

Given two covar iance matrices R and S for a given elliptically con toured distribution, we show how simple inequalities between the matr ix elements imply that ER(f)< Es(f), e.g., when x = (xil,i ...... i,) is a mult i index vector and f ( x ) = rain max rain max. . .xi l ..... i,, i l i2 i3 or f(x) is the indicator funct ion of sets such as (3 U N U...rx, ...... ~._-<;o, ..... ,~ i l i2 i3

The modular variety of non singular and complete hyperelliptic curves with level-two structure of genus 3 is a 5-dimensional quasi projective variety which admits several standard compactifications. The first one comes from the period map, which realizes this variety as a sub-variety of the Siegel modular variety of level two and genus three H3/Γ3[2]. We denote the hyperelliptic locus by I3[2] ...
