An assumption generally subscribed in evolutionary economics is that new technological paradigms arise from advances is science and developments in technological knowledge. Demand only influences the selection among competing paradigms, and the course the paradigm after its inception. In this paper we argue that this view needs to be adapted. We demonstrate that in the history of computing tech...

The ISO 9000 experiences of the same sample of organisations over a five year time period is examined in this paper. The responses to a questionnaire sent out at the end of 1999 to companies which had a reasonably long term experience with the ISO 9000 series quality system are analysed. These companies were ISO 9000 series certified before 1994 when the authors conducted their first survey on ...

As the $100B therapeutic monoclonal antibody (mAb) market continues to grow, developers of therapeutic mAbs increasingly face the need to strengthen patent protection of their products and enforce their patents in courts. In view of changes in the patent law landscape, patent applications are strategically using information on the precise binding sites of their mAbs, i.e., the epitopes, to supp...

Drosophila melanogaster polytene chromosomes display specific banding pattern; the underlying genetic organization of this pattern has remained elusive for many years. In the present paper, we analyze 32 cytology-mapped polytene chromosome interbands. We estimated molecular locations of these interbands, described their molecular and genetic organization and demonstrate that polytene chromosome...

Organic compounds with surfactant properties are commonly found in atmospheric aerosol particles. Surface activity can significantly influence the cloud droplet forming ability of these particles. We have studied the cloud droplet formation by two-component particles comprising one of the organic surfactants sodium octanoate, sodium decanoate, sodium dodecanoate, and sodium dodecyl sulfate, mix...

Although there is no routine procedure for determination of serum markers in patients with malignant melanoma (MM), some markers are being studied as potentially useful prognostic tools. Serum lactate dehydrogenase (LDH), protein S-100B, melanoma-inhibiting activity (MIA) and tyrosinase may correlate with melanoma progression. In this study, the results of determination of S100 protein, LDH, MI...

Cardiac arrest (CA) is the primary cause of death in industrialized countries. Successful resuscitation rate is estimated of about 40%, but a good neurological outcome remains difficult to achieve. The majority of resuscitated victims suffers of a pathophysiological entity termed as "post resuscitation disease". Today's efforts are mainly pointed to the chain of survival, often devoting less at...

BACKGROUND Protein S100B is considered to be a marker of brain damage, but there is a paucity of data regarding the utility of its assessment in brain-dead organ donors. The aim of the study was to compare serum protein S100B concentrations between brain-dead organ donors and patients with a confirmed permanent neurological deficit but without signs of brain death. METHODS The concentration o...
