When PSB is used with rock phosphate, it can save about 50% of the crop requirement of phosphatic fertilizer. [citation needed] The use of PSB as inoculants increases P uptake by plants. Simple inoculation of seeds with PSB gives crop yield responses equivalent to 30 kg P 2 O 5 /ha or 50 percent of the need for phosphatic fertilizers ...
The visible front on the material usually makes a well-defined angle typically 50–55° from the specimen axis as it moves down the sample. [5] During the propagation of the band the nominal stress–strain curve is flat. [4] After the band has passed through the material the deformation proceeds uniformly with positive strain hardening.
These intumescent materials produce a light char which is a poor conductor of heat, thus retarding heat transfer.Typically the light char consists of microporous carbonaceous foam formed by a chemical reaction of three main components: ammonium polyphosphate, pentaerythritol, and melamine. [2]
Cheat sheets were historically used by students without an instructor or teacher's knowledge to cheat on a test or exam. [1] In the context of higher education or vocational training, where rote memorization is not as important, students may be permitted (or even encouraged) to develop and consult their cheat sheets during exams.

The 10th Grade board examinations are conducted by the state board (), the Central Board of Secondary Education (All India Secondary School Examination) and the Council for the Indian School Certificate Examinations (). 10th Grade board exams are ...
[5] [6] Unlike plants, algae, and cyanobacteria, purple sulfur bacteria do not use water as their reducing agent, and therefore do not produce oxygen. Instead, they can use sulfur in the form of sulfide, or thiosulfate (as well, some species can use H 2 , Fe 2+ , or NO 2 − ) as the electron donor in their photosynthetic pathways. [ 5 ]
AerMet 340 alloy has a higher strength than AerMet 310. AerMet 340 is hardened differently from the other two varieties. The first hardening application is a solution treatment at 1,775 °F (968 °C) for 1 hour.
