An osmotically fragile L-form of Streptococcus pyogenes, type 12, was quickly rendered osmotically stable by decreasing the sodium chloride content of the growth medium and with the temporary use of oleic acid. The change from osmotic fragility to stability was accompanied by changes in cell yield, generation time, saturated/unsaturated fatty acid ratio of the membrane, and cytoplasmic protein ...

Thirty six wheat genotypes derived from diallel crosses from F1 to F3 and their parents were evaluated in six different environments for the stability of performance. Performance was measured by seed yield per plant under drought and non-drought stress conditions. The experiment was conducted as a randomised complete block design with three replications in over one year. Additive main effects a...

a powerful and convenient reaction procedure for the c-n coupling reaction (the buchwald-hartwig reaction), yielding products of n-arylanilines and n-arylamines in both conventional heating and microwave irradiation has been reported. the protocol utilizes a stable and new supper ferromagnetic nanoparticle chelating n-heterocyclic dicarbene palladium(ii) complex (pd-nhc) as catalyst which helps...

We evaluated 38 dura x pisifera (DP) oil palm progenies in four locations in Malaysia for genotype by environment interaction and genotypic stability studies. The DP progenies derived from crosses between pisifera palms of AVROS, Serdang S27B, Serdang 29/36, and Lever Cameroon were chosen to be the males' parent and Deli dura palms designated as females' parent. All the locations differed in te...

Given an ordering of the vertices of a graph one can construct a maximal stable set of that graph applying a simple greedy algorithm. By investigating certain conditions on the orderings of the vertices, N.V.R. Mahadev and B.A. Reed [5] characterized a class of graphs for which a maximum stable set and hence also the stability number can be computed in polynomial time in this way. In this paper...

The stability of synchronized states (including equilibrium point, periodic orbit or chaotic attractor) in stochastic coupled dynamical systems (ordinary differential equations) is considered. A general approach is presented, based on the master stability function, Gershgörin disc theory and the extreme value theory in statistics, to yield constraints on the distribution of coupling to ensure t...

The need for higher performance electronics for space and defense applications has driven the development of InP heterojunction technologies. For the past 10 years, TRW has been developing InP HBT and HEMT technologies for mission critical applications [1– 3]. Consistent and continuous improvements in the basic MBE structure and process technology have enhanced device and circuit performance, p...
