Escherichia coli 16S-like ribosomal RNAs from
eubacterial, archaebacterial and eukaryotic organisms have
several universally conserved sequence zones which are
proposed to be single-stranded. A clear function for all
of these regions has not yet been defined. To evaluate the
roles of these sequence zones in protein synthesis,
knowledge of their...
Crosses between four near isogenic lines for height reducing genes
Rht₁ and Rht₂ and one agronomically superior dwarf line, including
generations through F₃ with reciprocal backcrosses constituted the
experimental materials. Mean, range and standard deviation values for
eleven traits pertaining to the different generations were obtained.
Heterosis and inbreeding depression...
Tetrachlorethene (PCE) and trichloroethene (TCE) were common solvents used in the 1970’s that are now frequently observed groundwater contaminants. One method of remediating these contaminants is in-situ bioremediation that uses a dechlorinating microbial population. The microbial population performs the sequential reductive dechlorination of PCE and TCE to cis-1,2-dichloroethene (c-DCE), vinyl...
Polyoxometalates (POMs) are anions consisting of three or more early transition metals ™ (Gr V and VI) oxoanions (in their highest oxidation state) linked together by a shared oxygen bond to form a 3D framework. Polyoxometalates (POMs) are a rapidly growing class of metal oxo clusters with a wide range...
Clean technologies can address multiple challenges associated with climate change, environmental protection, and human health. However, the impact desired by introduction of such technologies is achievable only if new options effectively replace inefficient, conventional practices. This ‘design for adoption’ requires understanding of user motivations, associated beliefs, context of use, and...
Traffic signal countdown timers (TSCT) are innovative, practical and cost effective technologies with the potential to improve efficiency and safety at signalized intersections. The purpose of these devices is to assist motorists in decision making at signalized intersections with real time signal change information. While successful implementation of these devices...
The silviculture of mixed dipterocarp forests of Peninsular Malaysia can potentially be improved by developing quantitative tools and guidelines for this forest type. This thesis addresses three key objectives; 1) to test the hypothesis that a maximum size-density relationship can be identified in hill dipterocarp forests of Peninsular Malaysia, 2)...
Cephalosporium stripe, caused by the soil-borne ascomycete Cephalosporium gramineum, is becoming an increasingly important disease of winter wheat (Triticum aestivum) in several areas of the world, especially where stubble mulch is practiced to maintain soil moisture and prevent erosion. As cultural control of the disease is infeasible and no fungicides...
Chalan Beel, a wetland situated in the North Western Bangladesh is a very potential wetland with immense biodiversity and fisheries value. Its management problem has engulfed with suggestions ranging from private leasing, joint administration by public representation and government and community based approaches. However, nothing sustainable so far emerged concerning...
