The usual supermembrane solution ofD = 11 supergravity interpolates between R11 and AdS4× round S7, has symmetry P3×SO(8) and preserves 1/2 of the spacetime supersymmetries for either orientation of the round S7. Here we show that more general supermembrane solutions may be obtained by replacing the round S7 by any seven-dimensional Einstein space M7. These have symmetry P3 × G, where G is the ...

Organohalide respiration is an anaerobic bacterial respiratory process that uses halogenated hydrocarbons as terminal electron acceptors during electron transport-based energy conservation. This dechlorination process has triggered considerable interest for detoxification of anthropogenic groundwater contaminants. Organohalide-respiring bacteria have been identified from multiple bacterial phyl...

We previously reported that cytosolic fractions of bovine brain contain two immunologically distinct forms of phospholipase C (PLC), PLC-I and PLC-II. We now report the purification of another form of inositolphospholipid-specific phospholipase C from bovine brain cytosol, designated PLC-III, and the comparison of the catalytic properties of the three isozymes. Approximately 450 micrograms of p...

Tabasconura gen. nov. (Neanuridae) and type species T. tapijulapana sp. nov., are described and illustrated. The new genus possesses all characters of the tribe Sensillanurini Cassagnau, and is characterised by the presence of slightly elongated tubercles on the body and also elongation and thickening of the sensillum S2 as well as S7 on antennal segment IV. Development of S7 is a character of ...

Previous phylogenetic analyses based on bluetongue virus (BTV) gene segment L3, which encodes the inner core protein, VP3, indicated a geographical distribution of different genotypes. The inner core protein, VP7, of BTV has been identified as a viral attachment protein for insect cell infection. Because the inner core proteins are involved with infectivity of insect cells, we hypothesized that...

For prokaryotes in vitro, 16S rRNA and 20 ribosomal proteins are capable of hierarchical self- assembly yielding a 30S ribosomal subunit. The self-assembly is initiated by interactions between 16S rRNA and three key ribosomal proteins: S4, S8, and S7. These proteins also have a regulatory function in the translation of their polycistronic operons recognizing a specific region of mRNA. Therefore...

Automatic production line training system is used to simulate the actual process of industrial production. According to the actual needs of teaching instrument market at present, for the purpose of students or staff training, the author designs a practical automatic production line simulation training system. Using Siemens S7-200 PLC as the control core, setting sensors, buttons and lights, pow...
