Effect of hypoxia and glutamine or glucose deprivation on the expression of retinoblastoma and retinoblastoma-related genes in ERN1 knockdown glioma U87 cell line
(Scientific Research Publishing, 2012-01)The expression of retinoblastoma and several retinoblastoma-related genes was studied in glioma cell line U87 and its subline with knockdown of ERN1 (endoplasmic reticulum—nuclei-1), the main endoplasmic reticulum stress ... -
Intellectual CAD for Three-Tier Wide Band WDR Filters
(Scientific Research Publishing, 2012-01)The paper presents an original physical points of an intellectual CAD system designing for three-tier wide band waveguide-dielectric filters with LM modes. On the basis of formalized physical knowledge about the behavior ... -
Molecular docking investigation for Indonesian H274Y mutant neuraminidase type 1 with neuraminidase inhibitors
(Scientific Research Publishing, 2012-01)The aim of this study is to get insight the interaction between Indonesian H274Y mutant neuraminidase with four inhibitors. Not only to seek preferable inhibitor to be used, but also to investigate the interaction occurred, ... -
Numerical Investigation of Flow Structure Interaction Coupling Effects in Hard Disk Drives
(2012-02)This paper studies the flow structural interaction (FSI) within a hard disk drive (HDD) through the use of a novel coupling method. The interaction studied was the fluid induced vibration in the HDD. A two step coupling ... -
The Mesoscopic Constitutive Equations for Polymeric Fluids and Some Examples of Viscometric Flows
(2012-02)Constitutive equations for melts and concentrated solutions of linear polymers are derived as consequences of dynamics of a separate macromolecule. The model is investigated for viscometric flows. It was shown that the ... -
A Fatigue Analysis of a Hydraulic Francis Turbine Runner
(2012-02)In this work, the estimation of crack initiation life of a hydraulic Francis turbine runner is presented. The life prediction is based on the local strain approach to predict the initiation life. First, the analysis is ... -

Genetic diversity among commercial coffee varieties, advanced selections and museum collections in Kenya using molecular markers
(Academic Journals, 2012-02)Molecular markers have effectively been applied to study genetic diversity and as markers of particular traits. This study assessed the diversity of twenty four (24) coffee genotypes using 10 Random Amplified Polymorphic ... -
The Extent of Students’ Initiation of Ideas in The Classroom
(University Of Port Harcourt, 2012-02-01)This study sought to identify the extent of students’ initiation of ideas in the classroom using three classroom interaction techniques. All senior secondary schools in Port Harcourt Local Government Area, ... -
Using Podcasts to Help Students Apply Informatics Concepts: Benefits and Unintended Consequences. CIN: Computers, Informatics Nursing
(2012-03)Despite requirements for robust health informatics education, a multitude of educators and policy analysts report that programs are not adequately preparing nurses to handle the bevy of technologies that will be a part of ... -
Is leaf pubescence of Cape Proteaceae a xeromorphic or radiation-protective trait?
(CSIRO Publishing, 2012-03)Although pubescence has traditionally been considered to be related to the water economy of plants, the results are ambivalent and vary between different species. We tested two contrasting hypotheses for the functional ... -
The ATPase activity of molecular chaperone HSP60 is inhibited by immunosuppressant mizoribine
(Scientific Research Publishing, 2012-04)The molecular chaperone HSP60 is a chaperonin homolog of GroEL. We had previously shown that the immunosuppressant mizoribine is bound directly to HSP60 and inhibited its chaperone activity. However, the inhibitory mechanisms ... -
Oxidized phospholipids modify plasminogen and apolipoprotein(a): Implications for vascular disease
(Scientific Research Publishing, 2012-04)Whereas the close structural homology between human plasminogen and apolipoprotein(a) has been known for a number of years only recent studies have revealed that both proteins carry linked oxidized phospholipids that may ... -
Interference Mitigation MAC Protocol for Cognitive Radio Networks
(Scientific Research Publishing, 2012-04)The growing demand for wireless services coupled with the limited availability of suitable electromagnetic spectrum is increasing the need for more efficient RF spectrum utilization. Spectrum allocated to TV operators can ... -
Coevolutionary fine-tuning: evidence for genetic tracking between a specialist wasp parasitoid and its aphid host in a dual metapopulation interaction
(Cambridge University Press, 2012-04)In the interaction between two ecologically-associated species, the population structure of one species may affect the population structure of the other. Here, we examine the population structures of the aphid Metopeurum ... -
