Abstract: Antimicrobial compositions including at least one acid and at least one anionic surfactant are provided. In particular, food contact antimicrobial compositions including at least one acid and at least one anionic surfactant provide efficacious virucidal activity, including against Norovirus, having acceptable use solution pH that do not require use of personal protective equipment (PPE), are surface compatible and do not leave residues on treated surfaces. Methods of cleaning a surface with the compositions are also provided and may beneficially eliminate the need to rinse the antimicrobial compositions after use.

Abstract: The invention discloses a lighting device (1) and a luminaire (3) comprising one or more lighting devices (1) mounted into a pole (2). The lighting device (1) comprises an optical module. The optical module directs the light from a light source (10) into two parts of light (L1, L2), wherein the first part of light (L1) and the second part of light (L2) are different in luminance intensity distribution. In particular, the optical module comprises a first optical element (20) directing light from a light source (10) into the first part of light (L1), and a second optical element (30) directing the light from the light source (10) into the second part of light (L2).

Abstract: The present invention provides a system and method for determining whether two or more parameters influence one another within a communications network by obtaining a set of measurements for two or more parameters. A correlation and a partial correlation between each of the parameters are then determined. A determination is then made as to whether the correlations and the partial correlations are statistically significant. Thereafter, a determination is made as to whether the two or more parameters, if any, influence one another based on the statistically significant correlations and partial correlations.
