Four types of Shiraz inlay (Khatam) samples were impregnated with nano-silver solution via spraying (S), a vacuum desiccator (VD), and immersion/dipping (I/D) for 2 h 24 techniques. The decay resistance dimensional stability evaluated after each treatment. specimens exposed to white-rot fungus 10 weeks by the agar-plate method, weight loss was determined assess decay. soaking in water measured....

Comparative work on human spatial cognition contrasts systems of calculating position and trajectory that involve body-relative reckoning frequently where the body in question is that of an egocentric observer with systems which rely on global coordinates such as compass directions not relative to the positions and orientations of moveable entities. I consider here a case from a Tzotzil speaker...

Let k be a field of characteristic 0. G reductive group over the ring Laurent polynomials R=k[x_1^{\pm 1},...,x_n^{\pm 1}]. We prove that has isotropic rank >=1 R iff it fractions k(x_1,...,x_n) R, and if this is case, then natural map H^1_{et}(R,G)\to H^1_{\et}(k(x_1,...,x_n),G) trivial kernel, loop reductive, i.e. contains maximal R-torus. In particular, we settle in positive conjecture V. Ch...

This means that the italicized sentences in (1) are required to be homogeneously true at subintervals of an interval of the type specified by the for-phrase. The examples in (1) already make an appropriate definition of the notion of homogeneity non-trivial, since states are argued to be homogeneous down to instants, while activities are homogeneous down to larger intervals whose precise size i...

The grassland ecosystem in the Northern-Tibet Plateau (NTP) of China is verysensitive to weather and climate conditions of the region. In this study, we investigate thespatial and temporal variations of the grassland ecosystem in the NTP using theNOAA/AVHRR ten-day maximum NDVI composite data of 1981-2001. The relationshipsamong Vegetation Peak-Normalized Difference Vegetation Index (VP-NDVI) a...
