A method for determining a source-dependent particle size distribution of an aerosol by an aerosol measuring device. First, a fraction parameter is determined that corresponds to a fraction of a source-dependent aerosol part of the aerosol. In addition, a particle size distribution of the aerosol particles is determined such that the source-dependent particle size distribution of the aerosol is determined from the fraction parameter and the particle size distribution. In terms of the device, the invention comprises an aerosol measuring device for determining a source-dependent particle size distribution of an aerosol, by means of which aerosol measuring device a fraction parameter can be determined that corresponds to a fraction of a source-dependent aerosol part of the aerosol. A particle size distribution of the aerosol particles can be determined such that the source-dependent particle size distribution of the aerosol can be determined from the fraction parameter and the particle size distribution.

The invention relates to a method for detecting a dengue infection in a patient blood sample, comprising the steps: a) Performing an analysis of prespecified parameters of blood platelets and prespecified types of blood cells in the sample and determining parameter values for the prespecified parameters of the platelets and the prespecified types of cells; b) Obtaining sample parameters from the values determined in step a); and c) Evaluating the sample parameters in relation to a prespecified criterion, wherein, if the criterion is fulfilled, a dengue infection is present.

Condensation associated with the collection and identification of airborne particles is detected. Upon the detection, one or more condensation countermeasures are triggered to address the condensation.

A bioaerosol detector is operated in accordance with one or more first inputs. Operating the bioaerosol detector includes filtering pathogens from the air, extracting genetic material from the filtered pathogens, and analyzing the extracted genetic material to identify the filtered pathogens. While operating the bioaerosol detector in accordance with the one or more first inputs, a change is identified in an operating condition for the bioaerosol detector. In response, the bioaerosol detector is operated in accordance with one or more second inputs. At least one input of the one or more second inputs is distinct from a respective input of the one or more first inputs.

An inflammatory marker is calculated using a nonlinear function including, as variables, a parameter associated with an erythrocyte aggregation and another parameter associated with an erythrocyte density. The parameter associated with the erythrocyte aggregation is calculated based on a syllectogram measured from a blood specimen. The parameter associated with the erythrocyte density is measured from the blood specimen.
