biological control of sugar beet damping-off of rhizoctonia solani ag-4 by two native streptomyces isolates (s2 and c) was evaluated in green house and field conditions. in dual culture, two streptomyces isolates inhibited mycelial growth of r. solani ag-4. besides, volatile components of s2 and c inhibited r. solani mycelial growth for 72 and 74 percentages, respectively. soil treatment either...

?2.25 45s Philosophical discussions of responsibility , freedom of the will and such subjects seem often to stand at an enormous distance from the more immediate problems of psychiatry and the law. That they should stand at some distance is inevitable and no bad thing, but to keep them too far apart for too long has, among other bad effects, the rather paradoxical one of making both parties con...

Laser-induced breakdown spectra (LIBS) were collected on a diverse suite of ∼2,600 geological standards using four laser energies (2.4–7.2 mJ) to assess how variations in irradiance from stand-off distance affect prediction accuracy. Mismatches and plasma temperatures between training datasets introduce substantial uncertainty major element predictions. For example, 2.4 mJ predict 7.2 data resu...

The aim of this study was to identify and explain the optimum projection angle that maximises the distance achieved in a standing long jump. Five physically active males performed maximum-effort jumps over a wide range of take-off angles, and the jumps were recorded and analysed using a 2-D video analysis procedure. The total jump distance achieved was considered as the sum of three component d...
