Optical glucose sensing using ethanolamine–polyborate complexes

An optical glucose sensor based on polyborate–amine complexes with an aggregation-induced emission mechanism.

A FRET-based biosensor for the detection of neutrophil elastase

The direct and specific detection of biomarkers activity is crucial as it can allow monitoring the state of tissue or wound, as well as the progression of the inflammatory process.

Encapsulation of FRET-based glucose and maltose biosensors to develop functionalized silica nanoparticles

Silicate nanoparticles with immobilized FRET-based biosensors were developed for the detection of glucose and maltose.

[Occurrence and evaluation of a law frequency noise in residential buildings]

Low-frequency noise emitted into the environment by technical equipment in the residential buildings, including equipment of workshops for services or production near these buildings, was measured. In the spectrum of noise derived from installations and equipment in residential buildings and shops low frequency (20-125 Hz) sounds and infrasounds (below 20 Hz) were detected. Their sources were mainly pumps in hydrophors, lifts, cooling machinery, central heating, air conditioning and ventilating installations. The analysed noise was in a small degree only damped by partitions in buildings and penetrated more easily than higher-frequency noise, without exceeding usually the permitted levels. Noises with dominating low-frequency sounds are regarded by the inhabitants as troublesome and causing various adverse psychosomatic effects, such as pulsation feeling, somnolence, headaches, nausea etc. The present system of noise assessment leaves low-frequency noise aside and fails to protect sufficiently the inhabitants against this nuisance.

[Determination of acoustic climate inside high schools in comparison with elementary schools]

The evaluation of acoustic conditions in four high schools showed that acoustic climate in high schools is more favourable than in elementary schools. During breaks the noise in corridors is about 77 dB (about 9 dB lower than in elementary schools). During lessons these differences are lower. In comparison to the elementary schools the noise level both in the corridors and in the classrooms is about 5 dB lower (60 i 62 dB respectively). During lessons the noise level depends mainly on number of pupils, manner of teaching, a type of task performed by schoolchildren and the day of the week. The work in groups is noisiest (average more 5-7 dB than during lectures). The more favourable acoustic conditions are in classes below 25 pupils but in classes above 30 pupils the noise level during lessons increases about 3dB. The noise in classroom depends also on period of duration of the lesson and the day of the week. However it was not observed significant differences in daily distribution of the noise level, subject of the lesson or year of schooling. Resultant daily noise exposure of schoolchildren in high schools during their school time is 73 dB and is about 7 dB lower than in elementary schools.
