a series of x(co, mn)/tio2 catalysts (x=2–12wt.%) containing 25%co and 75%mn were prepared by the co-impregnation method. all prepared catalysts have been tested in fischer-tropsch synthesis for production of c2-c4 olefins. it was found that the catalyst containing 8wt.%(co,mn)/tio2 is an optimal catalyst for production of c2-c4 olefins. the effect of operation conditions such as the h2/co mola...

Francisella tularensis (Ft), a gram-negative intracellular bacterium, is the etiologic agent of tularemia. Infection of mice with <10 Ft Live Vaccine Strain (Ft LVS) organisms i.p. causes a lethal infection that resembles human tularemia. Here, we show that immunization with as little as 0.1 ng Ft LVS lipopolysaccharide (Ft-LPS), but not Ft lipid A, generates a rapid antibody response that prot...

The mining of frequent patterns in databases has been studied for several years, but few reports have discussed fault-tolerant (FT) pattern mining. FT data mining is more suitable for extracting interesting information from real-world data that may be polluted by noise. This paper considers proportional FT mining of frequent patterns. The number of tolerable faults in a proportional FT pattern ...

In plants, successful reproduction requires the proper timing of flowering under changing environmental conditions. Arabidopsis FLOWERING LOCUS T (FT), which encodes a proposed phloem-mobile florigen, has a close homologue, TWIN SISTER OF FT (TSF). During the vegetative phase, TSF shows high levels of expression in the hypocotyl before FT induction, but the tsf mutation does not have an apparen...

FLOWERING LOCUS T (FT) protein is known to be part of the mobile flowering inducing "florigen" signal in plants, but it may not be acting alone. This article reviews the data that FT mRNA can also move systemically throughout the plant and into the shoot apical meristem (SAM) independently of the FT protein. There is a promotion of flowering when increased levels of virally expressed FT mRNA ar...

in a novel dual bed reactor fischer-tropsch synthesis was studied by using two diffrent cobalt catalysts. an alkali-promoted cobalt catalyst was used in the first bed of a fixed-bed reactor followed by a rutenuim promoted cobalt catalyst in the second bed. the activity, product selectivity and accelerated deactivation of the system were assessed and compared with a conventional single bed react...
