Automation of paddy straw bale combustor technology was achieved by designing a microcontroller based logic control system for controlling feeding, ensuring complete combustion and cleaning the grate removing bottom ash. The generates flue gas at 350 °C to maintain greenhouse air temperature 10 higher (for 24 h continuous operation) than ambient during winter months Ludhiana climate (30.56 °N),...

KvLm, a novel bacterial depolarization-activated K(+) (Kv) channel isolated from the genome of Listeria monocytogenes, contains a voltage sensor module whose sequence deviates considerably from the consensus sequence of a Kv channel sensor in that only three out of eight conserved charged positions are present. Surprisingly, KvLm exhibits the steep dependence of the open channel probability on ...

AIMS To maximize spore production by Bacillus amyloliquefaciens B128, and its antagonism to the fungal pathogen Botrytis elliptica B061. METHODS AND RESULTS In the 5-l stirred-tank bioreactor (STR), with the 0.5 vvm aeration rate, an agitation rate of 200 rev min(-1) significantly enhanced the spore yield compared to the same in 300 rev min(-1) cultivations. In a 20-l airlift bioreactor (ALR)...

The classical isoperimetric inequality in R states that the surface of smallest area enclosing a given volume is a sphere. We show that the least area surface enclosing two equal volumes is a double bubble, a surface made of two pieces of round spheres separated by a flat disk, meeting along a single circle at an angle of 120◦.

The classical isoperimetric inequality states that the surface of smallest area enclosing a given volume in R3 is a sphere. We show that the least area surface enclosing two equal volumes is a double bubble, a surface made of two pieces of round spheres separated by a flat disk, meeting along a single circle at an angle of 2π/3.

Trehalose-mannitol agar and various broth formulations thereof were evaluated for the differentiation of Staphylococcus epidermidis from other common coagulase-negative staphylococcal species isolated from human blood cultures. While this differentiation was accurately made on trehalose-mannitol agar in 18 h, modification of the medium to a broth formulation containing 2% each trehalose and man...

In this paper, we show that the so-called “double bubbles” are not downward dense in the d.c.e. degrees. Here, a pair of d.c.e. degrees d1 > d2 > 0 forms a double bubble if all d.c.e. degrees below d1 are comparable with d2.
