objective: the world is currently facing with various problems including water and soil pollution as well as a major threat to the health of the citizens due to the advancement at human civilization, technology development, pesticides and chemical fertilizers application, the increasing exploitation of natural resources by the agricultural sector and the increasing usage of fossil energy. there...

After the fall of the Roman Empire in AD 476, scientific progress in Europe had come to a standstill. This era between fall of Rome and the Renaissance is commonly known as the dark ages. However, from the 8th till 13th century, scientific and cultural knowledge had flourished in the Islamic world. This period, which began soon after the establishment of the Abbasid Khalifate in Baghdad in the ...

Introduction: Uner Tan syndrome (UTS) consists of quadrupedal locomotion (QL), impaired intelligence, and dysarthric or no speech. Previously, I described the walk of cases with UTS as diagonal sequence (DS) because of ipsilateral limb interference, which is mostly observed in nonhuman primates with DS QL. The only gait analysis previously performed for UTS was of a few cases from only one fami...

In bacteria, transformation and restriction-modification (R-M) systems play potentially antagonistic roles. While the former, proposed as a form of sexuality, relies on internalized foreign DNA to create genetic diversity, the latter degrade foreign DNA to protect from bacteriophage attack. The human pathogen Streptococcus pneumoniae is transformable and possesses either of two R-M systems, Dpn...

BACKGROUND Despite a plethora of bioluminescent reporter genes being cloned and used for cell assays and molecular imaging purposes, the simultaneous monitoring of multiple events in small animals is still challenging. This is partly attributable to the lack of optimization of cell reporter gene expression as well as too much spectral overlap of the color-coupled reporter genes. A new red emitt...

Cells of the 16-cell mouse embryo endocytose horseradish peroxidase (HRP) which becomes localized in most cases to a juxtanuclear position. Cells that have ingested HRP in intact embryos, and cells dissociated from embryos prior to culture in HRP, showed similar patterns of cytoplasmic distribution of the ingested enzyme. Cells in the embryo in situ were incubated in HRP, and then labelled with...

Different cultures influence the way the members of a society view and perceive the world. This principle is important in the translation phenomenon. What is important for a translator is the purpose of conveying the message of the source text in a way understandable for the audience in the target text (TT). Therefore, every translator should have some knowledge about how to deal with different...

We study a 2× 2 system of non-strictly hyperbolic conservation laws arising in three– component gas flooding for enhanced oil recovery. The system is not strictly hyperbolic. In fact, along a curve in the domain one family is linearly degenerate, and along two other curves the system is parabolic degenerate. We construct global solutions for the Riemann problem, utilizing the splitting property...
