Zebu cattle infected with either Trypanosoma congolense EATRO 1800 or Trypanosoma vivax EATRO 1721 had suppressed humoral immune responses to Leptospira biflexa injected intravenously and to attenuated Brucella abortus injected subcutaneously. T. congolense infections were more suppressive than T. vivax infections. In cattle infected with T. vivax, the suppression of immune responses to both ba...

Two polypeptides of 50 and 45 kDa were adenylated by incubation of a mitochondrial extract from Leishmania tarentolae with [alpha-32P]ATP. These proteins were components of a complex that sedimented at 20S in glycerol gradients and migrated as a single band of approximately 1800 kDa in a native gel. The facts that RNA ligase activity cosedimented at 20S and that the ATP-labeled p45 and p50 poly...

In England in 1800 a profound change occurred that ushered in an important component in the regime of modern economic growth. In pre-industrial England, from 1250 to 1800, the rich produced many more surviving children than the poor. From 1800 to 1875 there was no association between wealth and net fertility. And after 1875 wealth became strongly negatively associated with net fertility. Why th...

A multiple input and multiple output (MIMO) antenna that comprises a printed microstrip antenna and a printed double-L sleeve monopole antenna for LTE 1800 wireless application is presented. The printed double-L sleeve monopole antenna is fed by a 50 ohm coplanar waveguide (CPW). A novel T-shaped microstrip feedline printed on the other side of the PCB is used to excite the waveguide's outer sh...

It has been shown experimentally for the first time that diffusion of cesium n rhenium takes place at irradiation of atoms flux heated up to Т ≤ 1800 K ( ) Re 1010 -C. Analysis of thermal desorption spectra showed that cesium forms two high-temperature phases during adsorption of cesium on graphite monolayer in rhenium heated up to 1800 K. The first, intercalated phase starts filling immediatel...
