We have cloned an internal fragment of the putative transoisase gene of MLE in the silkworm, Bombyx mori, using PCR method with degenerative oligonucleotide primers designed to represent regions of amino acids encoding transposase. The resulting PCR clone, designed as BmoMAR, cords a partial ORF(152 a.a.) of MLE in which interrupted by five stop codons, and the sequence of its deduced amino acids showed 37% homology with Mos1, an active mariner, from Drosophila mauritiana. Furthermore, the BmoMAR exhibits nucleotide and amino acid homology with 59% and 37% from Apis mellifera and D. mauritiana 7.9 clone, respectively. This result strongly that a MLE is present in the genome of B. mori.

The $Calder{\acute{o}}n$-Zygmund type estimate is proved for elliptic obstacle problems in bounded non-smooth domains. The problems are related to divergence form nonlinear elliptic equation with measurable nonlinearities. Precisely, nonlinearity $a({\xi},x_1,x^{\prime})$ is assumed to be only measurable in one spatial variable $x_1$ and has locally small BMO semi-norm in the other spatial variables x', uniformly in ${\xi}$ variable. Regarding non-smooth domains, we assume that the boundaries are locally flat in the sense of Reifenberg. We also investigate global regularity in the settings of weighted Orlicz spaces for the weak solutions to the problems considered here.

The purpose of this study is to analyze the outcomes of experts' survey for Cultivation techniques of good seed bulb in garlics program, purpose of introduction, and performance analysis this program. As a result of survey on new technology adoption to be cultivated in cultivation techniques of good seed bulb in garlics, technique satisfaction scored the highest with 4.3 points whereas innovation scored 4.21 points. On the other hand, risk scored the lowest with 2.53 points. Also, using BMO model business attractiveness and business fit scored 44 points, 45points respectively. Thus, the project rate of success were analyzed by more than 80 per cent. Finally, the management performance is analyzed on the garlic farms by selecting the highest awareness collected. As a result of effects after new technology adoption, 43% of the surveyees stated that the relative management costs dramatically decreased, and increase in production.

We consider Holder estimates for ∂ in analytic polyhedra. In the case of dimension 2, it preserves exact Ho1der regularity, and it maps bounded (0,1)-forms into BMO with respect to volume measure.
