On the maximal Operator Associated with Certain Rotational Invariant measures

Acta mathematica Sinica,English Series 2010年第6期26卷 993-1004页

作者： Adrián infante Fernando SORIA Department of mathematics Universidad Simn Bolívar Department of mathematics Universidad Autnoma de Madrid

The aim of this work is to investigate the integrability properties of the maximal operator mu,associated with a non-doubling measure μ defined on Rn. We start by establishing for a wide class of radial and increasing measures μ that mu is bounded on all the spaces Lu^p（R^n）,P〉***,we show that there is a radial and increasing measure p for which mμ does not map Lμ^p（R^n） into weak Lμ^p（R^n）,1≤p〈∞.

mining diversity of the natural biorefinery housed within Tipula abdominalis larvae for use in an industrial biorefinery for production of lignocellulosic ethanol

引用

Insect Science 2010年第3期17卷 303-312页

作者： dana m. Cook Joy Doran-Peterson microbiology Department University of Georgia Athens Georgia USA

Although they are the largest taxonomic group of animals, relatively few insects have been examined for symbiotic relationships with micro-organisms. However, this is rapidly changing because of the potential for examination of the natural insectmicrobe-lignocellulose interactions to provide insights for biofuel technology. micro-organisms associated with lignocellulose-consuming insects often facilitate the digestion of the recalcitrant plant diet; therefore these microbial communities may be mined for novel lignocellulose-degrading microbes, or for robust and inexpensive biocatalysts necessary for economically feasible biofuel production from lignocellulose. These insect-microbe interactions are influenced by the ecosystem and specific lignocellulose diet, and appre- ciating the whole ecosystem-insect-microbiota-lignocellulose as a natural biorefinery provides a rich and diverse framework from which to design novel industrial processes. One such natural biorefinery, the Tipula abdominalis larvae in riparian ecosystems, is reviewed herein with applications for biochemical processes and overcoming challenges involved in conversion of lignocellulosic biomass to fuel ethanol. From the dense and diverse T. abdominalis larval hindgut microbial community, a cellulolytic bacterial isolate, 27C64, demonstrated enzymatic activity toward many model plant polymers and also produced a bacterial antibiotic. 27C64 was co-cultured with yeast in fermentation of pine to ethanol, which allowed for a 20% reduction of commercial enzyme. In this study, a micro-organism from a lignocellulose-consuming insect was successfully applied for improvement of biomass-to-biofuel technology.

Foraminiferal biostratigraphy of the miocene Qom Formation, northwest of the Qom, Central Iran

Frontiers of Earth Science 2018年第1期12卷 237-251页

作者： Jahanbakhsh DANESHIAN Leila RAmEZANI dana Geology Department Kharazmi University Tehran 15719-14911 Iran

Near Dochah, in the type area of the Qom Formation, Central Iran, the miocene is partly developed in pelagic facies. From the 894.1 meter thick, ＇a to e＇ members of this section, 152 samples were collected. Abundant planktonic foraminifera let us correlate the study section with the global planktonic foraminifera biozonations. High diversity of foraminifera in the study section allow us to adapt the study succession to global biozonations. Twenty-seven genera and thirty-four species are reported for the first time from the Dochah section. First reports of Praeorbulina sicana and Praeorbulina transitoria in the upper part of this section led to recognition of the Praeorbulina sicana lower occurrence subzone （m5a） biozone with a late Late Burdigalian age.
