A Novel Ultra-Wideband Monopole Antenna with Band-Stop Characteristic
(Scientific Research Publishing, 2011-10)In this letter, a simple monopole antenna with variable band-notched characteristic for ultra wide band (UWB) function is proposed. Two L-shaped quarter-waveguide resonators coupled to the ground plane with two shorting ... -
HPV positivity varies with technique and primer set, in formalin-fixed paraffin-embedded benign and malignant breast tissue from Malta
(Scientific Research Publishing, 2011-10)The role of human papillomavirus in breast cancer pathogenesis is an area of considerable debate following differing results from all over the world. This study analyzed paraffin embedded tissue from 19 patients with benign ... -
JnCML-like, an EF-hand motif-containing gene seasonally upregulated in the transition zone of black walnut (Juglans nigra L.)
(Scientific Research Publishing, 2011-10)The economic value of a black walnut (Juglans nigra L.) tree is strongly determined by the quality and quantity of darkly colored heartwood in its stem. To understand the regulation of heartwood formation, we analyzed the ... -
Codon bias of influenza a viruses and their hosts
(Scientific Research Publishing, 2011-10)The Influenza A virus remains an annual and worldwide health concern due to its fast evolutionary rate. There are two major forms of Influenza evolution: drift, caused by mutations, and shift, which results from the exchange ... -
Cytosolic chaperonin CCT possesses GTPase activity
(Scientific Research Publishing, 2011-10)Cytosolic chaperonin CCT (also known as TRiC) is a hetero-oligomeric cage-like molecular chaperone that assists in protein folding by ATPase cycle-dependent conformational changes. However, role of the nucleo-tide binding ... -
Comparison of Indoor Localization Systems Based on Wireless Communications
(Scientific Research Publishing, 2011-10)Localization using a Wireless Sensor Network (WSN) has become a field of interest for researchers in the past years. This information is expected to aid in routing, systems maintenance and health monitoring. For example, ... -
EGR1 is essential for transcriptional regulation of BMPR2
(Scientific Research Publishing, 2011-10)In this study, RLM-RACE was used to identify the transcriptional start site 387 bp upstream of the translational start. Evolutionarily conserved transcription factor binding sites were identified, and a series of luciferase ... -
Dengue Vaccines: Challenge and Confrontation
(Scientific Research, 2011-11)Dengue has been recognized as one of the most important vector-borne human diseases. The disease is induced by dengue virus infection resulting from the bite of an infected Aedes spp. mosquito after imbibing the tainted ... -
A Finite Element Approximation of the Stokes Equations
(2011-12)In this work, a numerical solution of the incompressible Stokes equations is proposed. The method suggested is based on an algorithm of discretization by the unstable of Q1 – P0 velocity/pressure finite element ... -
How to Identify Latent Systolic Dysfunction and Post Operative Risk in Patients with Mitral Incompetence and Normal Ejection Fraction?
(Scientific Research, 2011-12)Purpose: To study the significance of impaired positive peak rate of left ventricular (LV) pressure development (MR + dp/dt) and global systolic strain (GLPSS) values in patients presented with significant mitral incompetence ... -
A Wireless Sensor Network Solution for Precision Agriculture Based on Zigbee Technology
(Scientific Research Publishing, 2011-12)Wireless Sensor Networks (WSNs) have attracted much atten tion in recent years. The potential applications of WSNs are immense. They are used for collecting, storing and sharing sensed data. WSNs have been used ... -
The Agricultural Ethics of Biofuels: The Food vs. Fuel Debate
(2012)Plant-based transportation fuels were the focus of extended criticism in the press, especially during 2008 when a portion of the blame for a spike in global food prices was associated with growth of the United States’ ... -
An Alternative Use of Horticultural Crops: Stressed Plants as Biofactories of Bioactive Phenolic Compounds
(2012)Plants subjected to abiotic stresses synthesize secondary metabolites with potential application in the functional foods, dietary supplements, pharmaceutical, cosmetics and agrochemical markets. This approach can be ... -
Aromatic Plants as a Source of Bioactive Compounds
(2012)Aromatic plants, also known as herbs and spices, have been used since antiquity as folk medicine and as preservatives in foods. The best known aromatic plants, such as oregano, rosemary, sage, anise, basil, etc., originate ... -
Evaluation of Biofertilizers in Irrigated Rice: Effects on Grain Yield at Different Fertilizer Rates
(2012)Biofertilizers are becoming increasingly popular in many countries and for many crops, but very few studies on their effect on grain yield have been conducted in rice. Therefore, we evaluated three different biofertilizers ... -
The Agricultural Resource Management Survey
(Emerald Group Publishing Limited, 2012)Purpose – The purpose of this article is to offer an introduction of the Agricultural Resource Management Survey (ARMS) for applied research in agricultural finance and farm management. Design/methodology/approach – This ... -
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
