A Computational Study of the Gas-Solid Suspension Flow through a Supersonic Nozzle
(Scientific Research, 2012-12)The present study focuses on numerical simulation of the gas-solid suspension flow in a supersonic nozzle. The Euler- Lagrange approach using a Discrete Phase Model (DPM) has been used to solve the compressible Navier-Stokes ... -
Characterization and Evaluation of Antibacterial Activities of Chemically Synthesized Iron Oxide Nanoparticles
(Scientific Research, 2012-12)The iron oxide nanoparticles have been synthesized in co-precipitation method using aqueous solution of ferric and ferrous ions with sodium salt. The synthesis of iron-oxide nanoparticles were validated by UV-Visible ... -
Soil Erosion Threatens Food Production
(2013)Since humans worldwide obtain more than 99.7% of their food (calories) from the land and less than 0.3% from the oceans and aquatic ecosystems, preserving cropland and maintaining soil fertility should be of the highest ... -
The Potential Impact of Climate Change on Soil Properties and Processes and Corresponding Influence on Food Security
(2013)According to the IPCC, global temperatures are expected to increase between 1.1 and 6.4 °C during the 21st century and precipitation patterns will be altered. Soils are intricately linked to the atmospheric/climate system ... -
Role of Arthropods in Maintaining Soil Fertility
(2013)In terms of species richness, arthropods may represent as much as 85% of the soil fauna. They comprise a large proportion of the meso- and macrofauna of the soil. Within the litter/soil system, five groups are chiefly ... -
Determination of Accuracy of Nursing Diagnoses Used by Nursing Students in their Nursing Care Plans
(2013)Aim: The aim of this study was to determine and evaluate appropriateness of nursing diagnoses with NANDA taxonomy used by second year nursing students in their nursing care plans. Methods: Retrospective design. Findings: ... -
Quality Assurance in Wound Management in a Developing Country: How Satisfied Are Our Patients?
(Scientific Research, 2013-01)Background: Quality is important in every setting especially in the health service where the needs of patients should be an utmost priority. However, this is sometimes not the situation in most health care centres due to ... -
Effect of 4% glycerol and low aeration on result of expression in Escherichia coli of Cin3 and three Venturia inaequalis EST’s recombinant proteins
(Scientific Research Publishing, 2013-01)The phytopathogenic fungus Venturia inaequalis causes scab of apple. Once this fungus penetrates the plant surface, it forms a specialized body called a stroma between the inner cuticle surface and the epidermal cell wall. ... -
Characterization of the role of Smu1 in nuclear localization of splicing factors in the mammalian temperature-sensitive mutant
(Scientific Research Publishing, 2013-01)A temperature-sensitive (ts) mutant of the CHO-K1 cell line, tsTM18, grows at 340C but not at 390C. Smu1 is the gene responsible for ts defects of tsTM18 cells. Previously, we found that the Smu1 ts defect altered the ... -
Frequently cutting restriction enzymes: Clearing the fog to see the ends
(Scientific Research Publishing, 2013-01)Telomeres, which are found at the ends of eukaryotic chromosomes, are composed of tandem arrays of repetitive sequences and safeguard genomic stability. Previous studies have revealed that telomeric repeats are also present ... -
Using Bayesian and Eigen approaches to study spatial genetic structure of Moroccan and Syrian durum wheat landraces
(Scientific Research Publishing, 2013-01)The Mediterranean durum wheat landraces are genetically diverse and important sources for improving resistance to abiotic and biotic stresses and developing adapted and productive durum wheat varieties in the Mediterranean ... -
Identification and characterization drought tolerance of gene LEA-D11 soybean (glycine max L. Merr) based on PCR-sequencing
(Scientific Research Publishing, 2013-01)Drought is one of the most damaging abiotic stress. Different plants response differently to drought stress. Abiotic stresses such as drought induced diverse physicological and molecular responses in plants. These responses ... -
Bax promoter G(-248)A polymorphism in a Turkish clinical breast cancer patients: A case-control study
(Scientific Research Publishing, 2013-01)Bax is an important protein involved in apoptotic process. Mutations of the Bax gene are known to af- fect protein expression and function. A promotor polymorphism G(-248)A in the 5’UTR of Bax gene may alter regulation of ... -
The molecular regulatory effect of intracerebroventricular thymulin on endotoxin-mediated NF-kB nuclear translocation and activation in vivo
(Scientific Research Publishing, 2013-01)The nuclear factor-kB (NF-kB) is one member of a ubiquitously expressed family of Rel-related transcription factors that serve as critical regulators of proinflammatory genes. The immunomodulatory potential of thymulin and ... -
Hybrid External Fixation for Open Severe Comminuted Fractures of the Distal Femur
