Greater Efficiency Observed 12 Months Post-Implementation of an Automatic Tube Sorting and Registration System in a Core Laboratory/ Veća Efikasnost Uočena 12 Meseci Posle Implementacije Sistema za Automatsko Sortiranje i Registrovanje Uzoraka u Centralnoj Laboratoriji

Summary

Bachground: Sample classification and registration have been recognized as important and time-consuming processes in laboratories. There is increasing pressure on laboratories to automate processes due to intense workload and reduce manual procedures and errors. The aim of the present study was to evaluate the positive effects of an automatic tube registration and sorting system on specimen processing.

Methods: An automatic tube registration and sorting system (HCTS2000 MK2, m-u-t AG, Wedel, Germany) was evaluated. Turnaround time (TAT), rate of sample rejection and unrealized tests were examined 12 months pre- and post-implementation of the automatic tube sorting and registration system.

Results: The mean TAT of routine chemistry immunoassay, complete blood cell count (CBC) and coagulation samples were significantly improved (P<0.001). The number of rejected samples and unrealized tests was insignificantly decreased post-implementation of the system (0.4% to 0.2% and 4.5% to 1.4%, respectively) (P>0.05).

Conclusions: By reducing delays and errors in the preanalytical processing and sorting of samples, significant improvements in specimen processing were observed after implementation of the system. These results suggest that an automatic tube registration and sorting system may also be used to improve specimen processing in a higher-volume core laboratory.

Characteristics of the butterflies on various forms of land uses

Abstract

The purpose of the work was to identify the occurrence of butterflies depending on landform uses and human influence on the population domination structure. The research was conducted in the ‘Krzywda’ field-and-forest Site occupying 172 ha. The area consists of the land leaving in fallow, meadows and wasteland including about 68 ha of swamps that are strongly eutrophic due to human economic activity. The area is subjected to artificial succession inhibition processes in the form of mowing and cutting of trees and shrubs. 32 species of butterflies were recorded during the research, that is, 20% of all species within this group occurring in Poland. The research has approved the great spatial and quantitative diversification of the occurring area of butterflies depending on the form of the land uses. The greatest number of species and their greatest populations were found in the land laying in fallow without the removal of the biomass. The least number of species and their specimens were collected in the unmown laying fallow land. Lycaena virgaureae was the most numerous species collected. The correct domination structure characterized by a small number of numerous species and a large number of species consisting of a low number of specimens. Processes observed in the studied Site subjected to various types of land use influence the occurrence diversity of this group of insects.
