PURPOSE Reliable in vitro cytotoxicity assays are essential for determining the responses of human normal and cancer-derived cells to therapeutic agents and also for the identification and pre-clinical evaluation of new drugs capable of selectively augmenting the susceptibility of cancer cells to conventional therapies. The clonogenic survival assay is considered as the "gold standard" in this ...

The HdS (hardware dependent Software) department of A1catel Bell Antwerp, part of the Carrier Data division is responsible for the design of embedded software, firmware and off-line test software towards verification and test of ASICs, PCB-boards and complete systems. The HdS designers are interested in an executable hardware model of the system to be designed as a virtual target for debugging ...

The increasing use of fossil fuels has led to increased emissions of sulphur oxides into the air, which is a major cause of acid rain. Legislation already adopted in 2009 stipulates that the maximum level of sulphur allowed in fuels is only 10 ppm. The process of hydrodesulphurization (HDS) used in refineries is based on very expensive physico-chemical techniques, and has limitations in the rem...

In 1981 Pecoraro and Chianelli reported a complete study of catalytic behavior of transition metal sulfides catalysts in hydrodesulfurization (HDS) of dibenzothiophene (DBT) [1], in which was found a periodic tendency of the metallic sulfides activity, where ruthenium sulfide showed the highest HDS activity. These results were corroborated later by Raje et al. [2] and Liaw et al. [3], further s...

The possibility of manipulating magnetic systems without applied magnetic fields have attracted growing attention over the past fifteen years. The low-power manipulation of the magnetization, preferably at ultrashort timescales, has become a fundamental challenge with implications for future magnetic information memory and storage technologies. Here we explore the optical manipulation of the ma...

Many cancers harbor homozygous DNA deletions (HDs). In contrast to other attributes of cancer cells, their HDs are immutable features that cannot change during tumor progression or therapy. I describe an approach, termed deletion-specific targeting (DST), that employs HDs (not their effects on RNA/protein circuits, but deletions themselves) as the targets of cancer therapy. The DST strategy bri...

Embedded hypermedia documents (HDs) are becoming more common in aircraft cockpits, powerand industrial-plant control panels, and other user interfaces to complex systems. These hypermedia documents are often large and heavily cross referenced, yet they must support extremely e cient and intuitive user navigation. Designing such documents well is di cult. In this paper, we describe a computer-ba...

Holographic data storage (HDS) is promising technology as novel with potentials of larger recording density and higher transfer rate. A computer-generated hologram (CGH) technique enables the optical configuration HDS to be in-line simple has therefore been applied HDS. In our previous papers, two approaches for increasing per a data-page number multiplexed holograms in medium have adopted impr...

BACKGROUND To estimate the prevalence of trachoma in the North Region of Cameroon in order to facilitate the planning of trachoma control activities in this region, a survey was carried out in 2011 and 2012 in 15 health districts (HDs). METHODOLOGY A cross-sectional, two-stage cluster random sampling survey was carried out. The survey focused on two target populations: children aged 1 to 9 ye...
