BACKGROUND Occupational diseases (ODs) are often under-reported. OD Medical Committees of the Greek Social Security Institute (Idryma Kinonikon Asfaliseon-IKA) are believed to be the only reliable source of data on ODs in Greece. AIMS To analyse the results of OD Medical Committees of IKA on the claims for OD Disablement Benefit (ODDB) during a 5 year period. METHODS Two hundred and ninety-...

BACKGROUND Retrospective studies to assess the distribution of oral diseases (ODs) are helpful in estimating the prevalence of oral diagnoses in the population, and thus help in preventive and curative services. Prevalence and frequency data for ODs are available from many countries, but information from Chile is scarce. MATERIAL AND METHODS This study investigated the frequency of OD in a Ch...

Oxide dispersion strengthened (ODS) alloys have been under intensive development over the past four decades due to their excellent high-temperature creep strength and good oxidation resistance. Nickel-based ODS alloys are the combination of gamma prime (γ’) strengthened superalloy with yttrium oxide evenly distributed throughout the matrix to allow the strength to be maintained to much higher t...

The author presents a significant approach to aligning multiple variables inside a cell by applying tabs to the ODS reporting process. Consequently what appeared to be one limitation in classical ODS reporting has been overcome. The technique makes it easy to adopt mixed patterns in presenting the result of proc report, which have become necessary under certain circumstances such as patient pro...

The influence of temperature on the surface structure of the octadecylsilica (ODS) bonded phase was investigated with a molecular dynamics (MD) simulation. The MD simulation was applied to a molecular model consisting of three parts: amorphous silica base, dimethyloctadecylsilyl ligands and n-hexane as a mobile phase solvent. More detailed information on the effect of temperature was obtained a...

A polymeric ODS column was applied to the resolution of triacylglycerol positional isomers (TAG-PI), i.e. 1,3-dioleoyl-2-palmitoyl-glycerol (OPO) and 1,2-dioleoyl-3-palmitoyl-rac-glycerol (OOP), with a recycle HPLC system. To investigate the ODS column species and the column temperatures for the resolution of a TAG-PI pair, a mixture of OPO and OOP was subjected to an HPLC system equipped with ...

Using sol-gel technology, a porous glass matrix (xerogel) is formed in a capillary column and acts as a support for a stationary phase of chromatographic particles used in capillary electrochromatography. Preparation of the sol-gel matrix and immobilization of the octadecylsilica (ODS) stationary phase occur in a single step. The presence of the particles in the column greatly reduces matrix cr...

Whether stratospheric cooling due to increases in well-mixed greenhouse gases (WMGHG) could increase the depletion of Arctic stratospheric ozone has been the subject of scientific and public attention for decades. Here we provide evidence that changes in the concentrations of ozone-depleting substances (ODS), not WMGHG, have been the primary driver of observed Arctic lower stratospheric trends ...

When adult males of the smaller brown planthopper, Laodelphax striatellus were fed on 2% crude rice (leaf and stem) extract containing 15% sucrose there were characteristic stylet sheaths deposited on parafilm membrane. Further bioassays with the butanol-soluble fr. of the extract revealed that it is highly effective for the insects. When the butanol fr. was charged on an ODS open column and el...
