Mating Strategies in Solitary Aphid Parasitoids: Effect of Patch Residence Time and Ant Attendance
(Springer, 2012-01)Mate finding and dispersal from the natal patch in parasitoid Hymenoptera are influenced by the availability of host resources and interactions with other organisms. We compared the mating behavior of three solitary aphid ... -
Somaclonal variations of Soybeans (Glycine Max. L. Merr) stimulated by drought stress based on random amplified polymorphic DNAs (RAPDs)
(Scientific Research Publishing, 2012-01)In soybeans, drought stress causes 50% yield losses. Breeding for drought tolerance in soybeans has been widely developed using various methods, among which is polyethylene glycol (PEG-6000) induction to simulate drought ... -
Hybrid Amplification: An Efficient Scheme for Energy Saving in MIMO Systems
(Scientific Research Publishing, 2012-01)In this paper, a new amplification scheme for adaptive MIMO systems is proposed and tested. In this ‘hybrid amplification’ configuration, different amplifiers with different peak powers are used. In this way, each transmitter ... -
Comparative gene expression analysis in stems of Dolichos purpureus and Arabidopsis thaliana
(Scientific Research Publishing, 2012-01)The outermost layer epidermis of a plant stem plays an important role in protection and environment-sensing. The mechanisms of sensing and response to the environment through the stem epidermis remain unclear. Here we ... -
SPT5 affects the rate of mRNA degradation and physically interacts with CCR4 but does not control mRNA deadenylation
(Scientific Research Publishing, 2012-01)The CCR4-NOT complex has been shown to have multiple roles in mRNA metabolism, including that of transcriptional elongation, mRNA transport, and nuclear exosome function, but the primary function of CCR4 and CAF1 is in the ... -
DOF transcription factors in developing peanut (Arachis hypogaea) seeds
(Scientific Research Publishing, 2012-01)DNA binding with one finger (DOF) transcription factors play important roles in storage material accumulation and morphogenesis of developing seeds. Oil and protein contents varied in different cultivars in important oil ... -
Microstrip Ultra-Wideband Filter with Flexible Notch Characteristics
(Scientific Research Publishing, 2012-01)A microstrip ultra-wideband (UWB) filter with unique shape, compactness, simplicity of operation and flexible notch characteristics is introduced. It is based on the fundamental and harmonic characteristics of a 50 Ohm ... -
Intergenic subset organization within a set of geographically-defined viral sequences from the 2009 H1N1 influenza A pandemic
(Scientific Research Publishing, 2012-01)We report a bioinformatic analysis of the datasets of sequences of all ten genes from the 2009 H1N1 influenza A pandemic in the state of Wisconsin. The gene with the greatest summed information entropy was found to be the ... -
Interaction of haptoglobin with hemoglobin octamers based on the mutation αAsn78Cys or βGly83Cys
(Scientific Research Publishing, 2012-01)Octameric hemoglobins have been developed by the introduction of surface cysteines in either the alpha or beta chain. Originally designed as a blood substitute, we report here the structure and ligand binding function; in ... -
A Comprehensive Parametric Study of Planar Inverted-F Antenna
(Scientific Research Publishing, 2012-01)This paper presents a comprehensive numerical and experimental study of Planar Inverted-F Antennas (PIFA) involving all the parameters which may affect the characteristics of PIFA. It is found that PIFA characteristics are ... -
Generalized PIC Detector for Distributed STBC under Quasi-Synchronization
(Scientific Research Publishing, 2012-01)In this paper, we propose a Generalized Parallel Interference Cancelation (G-PIC) approach for the detection of D-STBC under Quasi-Synchronization in the case of any number of relay nodes with just statistical information ... -
Picocystis salinarum (Chlorophyta) in saline lakes and hot springs of East Africa.
(2012-01)The occurrence of Picocystis salinarum in saline inland waters of East Africa was investigated using a polyphasic approach of small-subunit (SSU) rDNA phylogeny and light microscope observations. Recent studies have found ... -
Treatment of flower farm wastewater effluents using constructed wetlands in lake Naivasha, Kenya
(2012-01)Lake Naivasha, Kenya, is a fresh water lake currently experiencing severe environmental problems as result of pollution from agricultural effluents and urban water surface runoff, uncontrolled water abstraction, improper ... -
