the objective of this study is to develop a novel methodology integrating remote sensing, geographic information system technology and local spatial autocorrelation geo-computation for quick drought assessment. one group of drought indices, based on the condition of the vegetation, includes the normalized difference vegetation index (ndvi), anomaly of normalized difference vegetation index (ndv...

(3) G = 〈G, δ〉, G = 〈G, ǫ〉. We think of τ as given an inner class of real forms of G; G = 〈G, δ〉 is the the usual extended group. By a strong real form for G we mean with respect to G, i.e. in the inner class of τ . The involution μ is secondary. An important special case is μ = τ , which governs Hermitian representations of strong real forms G (in the inner class of τ). Often on the dual side ...

When rails are laid in a railway track, small gaps are left between the ends of adjoining rails to allow for the expansion of the rails when the temperature rises. Rail joints are provided to form a continuous rail path which are normally laid in standard lengths bolted together by fishplates. When two rail joints are exactly opposing each other, they are called square &#10&#10(side by side) jo...

background many clinical and experimental studies have been done to analyze the anatomical and functional aspects of the internal auditory canal (iac) in human beings since there are great inter-individual variability and structural variations that may occur regarding the other adjacent structures. objectives the purpose of this study was to characterize the morphology of the internal auditory ...

background: embryonic stem (es) cells are pluripotent cells conventionally isolated from early embryos. studies have shown that es cells serve as a practical model for biomedical studies. objective: the aim of the present study was to optimize culture conditions for establishment of es-like colonies from nmri mouse blastocysts as well as 2-cell stage embryos. materials and methods: both expande...

In this paper, we generalize the definitions of approximately inner $C_0$-groups and their ground states to the two- parameter case and study necessary and sufficient conditions for a state to be ground state. Also we prove that any approximately inner two- parameter $C_0$--group must have at least one ground state. Finally some applications are given.
