There are well over 200 species of fishes which are known to be venomous, and which are capable of inflicting serious and
potentially fatal wounds. Within this group, less than 5% have been studied even in the most preliminary manner and, to date, the
basic chemical structure of even a...
A study of deep levels of the emitter region of a
heterojunction bipolar transistor is investigated using deep
level transient spectroscopy (DLTS), deep level admittance
spectroscopy (DLAS), thermally stimulated capacitance
(TSCAP), and capacitance-voltage (C-V) profiling. The DX
center, with an activation energy of 0.45 eV, is the only
deep level...
Partial reactions of photosynthesis were examined in the wild
type strain and six photosynthetic mutants (8, 11, 26, 40, 50, a') of
Scenedesmus obliquus, strain D₃. A reproducible procedure for the
isolation of active chloroplast fragments from Scenedesmus was
developed. Several chloroplast reactions were examined, as well
as two in...
Papain-like leader proteases are found in diverse families of human, animal, plant, and fungal positive-strand RNA viruses. In addition to autocatalytic processing, these proteases play a variety of roles in the virus life cycle. In particular, the leader protease (L-Pro) of a prototype member of the Closterovirus genus, Beet yellows...
Plywood is the second largest, by value, wood-based product being imported by United Arab Emirates (UAE), below paper products and also second in terms of volume below sawn wood. Very few studies have been done of the UAE market for plywood. This thesis takes a scientific, marketing planning approach to...
As hardware becomes cheaper and cheaper, there is an
increasing interest in the implementation of distributed control
networks with microcontrollers. Such networks are usually
inexpensive and of high performance.
In this thesis work, a low-cost display control unit for COLAN, a
control-oriented network, is designed. The system is based on...
Shoot apex senescence is defined as the collective progressive
and deteriorative processes which ultimately terminate the functional
life of the shoot apex. Senescence of shoot apices of Pisum sativum
L. 'Alaska' as measured by cessation of stem elongation was delayed
by removal of flowers and by treatment with gibberellin A₃...
