Power System Frequency Control: Modeling and Advances evaluates the
control schemata, secondary controllers, stability improvement
methods, optimization considerations, microgrids, multi-microgrids,
and real-time validation required to model and analyze the dynamic
behavior of frequency in power systems. Chapters review a range of
advanced modeling and analytical considerations for single to
multi-area networks using traditional and hybrid sources, including
renewable sources, FACT devices and storage. The work also
considers broad aspects of upstream and downstream control
mechanisms which enable novel solutions in the area of automatic
generation control in power system networks. Highly recommended for
power system engineers, researchers and practitioners with
interests in load frequency control, automatic generation control,
linearized models of isolated microgrid, and multi-microgrid, and
hybrid LFC scheme, this book is an ideal resource on the topics
discussed.
Use of microtuber is advantageous than microplants but dormancy
problem of microtuber limits its production and use in the
laboratory and the field respectively. This book provides a proven
solution of dormancy breaking of freshly harvested microtuber with
5 to 7 days. A series of experiments in relation to production and
breaking of dormancy of potato microtubers were conducted during
2000-2003. Nitrogen at 45 and 60 mM with 300-500 mg/l CCC or 30-50
mg/l coumarin or 5 mg/l BAP or 10% sucrose produced higher
proportion of large size (>200 mg) microtubers after 105 days.
Treatment of intact microtuber with GA3 (0, 5, 10 and 15 mg/l) did
not show any noticeable effect on dormancy breaking, while soaking
of peeled microtubers treated with 0.1-1.0 mg/l GA3, 0.1 to 1.0
mg/l IAA and 0.01 to 0.1 mg/l Kin for 1 to 25 min and put on water
soaked cotton pad containing in petriplates showed >90%
sprouting within 7 days. Suberisation of peeled microtubers after
treatment had no effect on sprouting but was safe from rot, while
no rot of microtuber was observed while handling aseptically. This
book would be useful for the tissue culture laboratory as well as
basic seed potato growers.
Chilli (C. annuum and C. frutescens) is one of the most important
spice crops in Bangladesh as well as in the world. The genotypes of
chilli under investigation showed considerable variation in most of
the characters. The best dose of NPK per hectare were 100, 60, 100
or 125, 60, 100, respectively as in most cases these doses gave the
best result for obtaining the maximum yield and these two doses
were identical in most of the cases. 125 kg N, 60 kg P and 100 kg K
was the best dose for getting highest gross return, net return and
BCR and this dose was also identical to 100 kg, 60 kg and 100 kg
per hectare NPK, respectively. The best dose of S, Zn and B per
hectare was found to be 20 kg, 3 kg and 1.5 kg, respectively for
getting the highest yield and highest BCR. To get the highest seed
yield 100 kg N, 60 kg P and 100 kg K per hectare along with 20 kg
S, 3 kg Zn, 2 kg B per hectare were found the best dose.
