He proved in [3] this conjecture in the case of the second and third punctual Hilbert scheme of an algebraic K3 surface. In this paper, we observe that the results of [5] can lead to a more general conjecture concerning the Chow ring of an algebraic hyper-Kähler variety. Namely, the full statement of Theorem 0.1 can be interpreted by saying that any polynomial relation between [c2(TS)], [c1(Li)...

The question of whether cytochrome c could be functionally sorted to the mitochondrial intermembrane space along a "conservative sorting" pathway was investigated using a fusion protein termed pLc1-c. pLc1-c contains 3-fold targeting information, namely, the complete bipartite presequence of the cytochrome c1 precursor joined to the amino terminus of apocytochrome c. pLc1-c could be selectively...

We evaluated a novel strategy to improve the performance of outbreak detection algorithms, namely setting the alerting threshold separately in each region according to the disease incidence in that region. By using data on hand, foot and mouth disease in Shandong province, China, we evaluated the impact of disease incidence on the performance of outbreak detection algorithms (EARS-C1, C2 and C3...

abstract this study was performed in order to determine a suitable alternative substrate for peat in soilless culture in 2007. different plant wastes including carbonized rice hull, saw dust and dry pine leaves (pinus eldarica) were examined. treatments were 100% peat as control, peat plus dry pine leaves (1:1 v/v), peat plus carbonized rice hull (1:1 v/v) and peat plus saw dust (1:1 v/v). the ...

Tropical peat swamp lands in the Southeast Asia which store tremendous large amount of carbon in their peat layer and abundant biodiversity are now endangered by human activities such as deforestation, forest fires, land development and urbanization. To earlier start a better environmental policy for conservation of nature of the tropical peat swamp area is one of the preferential global issues...

A partially peat-extracted coastal bog contaminated by seawater was barren and required revegetation as a wetland. Peat fields were rectangular in shape, cambered in cross-section profile, and separated by drainage ditches. Common to all peat fields were symmetrical patterns in micro-topography with slopes between differences in elevation. Saline non-waterlogged slopes of ∼5% occurred as a symm...

The use of the phospholipid fatty acid (PLFA) composition of microorganisms to detect previous self-heating events was studied in naturally self-heated peat and in peat incubated under temperature-controlled conditions. An increased content of total PLFAs was found in self-heated peat compared to that in unheated peat. Two PLFAs, denoted T1 and T2, were detected only in the self-heated peat. In...

Historical records of mercury (Hg) accumulation in lake sediments and peat bogs are often used to estimate human impacts on the biogeochemical cycling of mercury. On the basis of studies of lake sediments, modern atmospheric mercury deposition rates are estimated to have increased by a factor of 3-5 compared to background values: i.e., from about 3-3.5 microg Hg m(-2) yr(-1) to 10-20 microg Hg ...

this experiment was carried out to investigate the effect of different substrate on growth and yield of gerbera flower. the experiment was performed using 10 treatments as fallow: fine sand, peat +fine sand (%25+%75), peat + fine sand ( %50 +%50), perlite + peat (%75 + %25), perlite + peat (%50 + %50), perlite + peat (%25 + %75), perlite + peat + expanded clay (%25 + %70 + %5), perlite + peat +...
