We report on the time response of higher-operating-temperature (HOT, T ∼200 K to 300 K) fast long-cutoff-wavelength infrared (LWIR) HgCdTe photodetectors. For a long time, photoconductive and photoelectromagnetic devices operating near room temperature have been used as fast (sub-nanosecond) photodetectors. Unfortunately, such devices suffer from relatively low detectivity. Recent efforts have focused...
The presented research aimed at determining the species composition and concentration of colony forming units (CFU) in two types of cattle barns for dairy cows and in a calf barn. The study was carried out in winter and summer 2012. The measurements took place in a free stall and tie stall barn and, additionally, in a calf barn. The mycological analysis of the air was conducted using the impact method,...
The aim of this research was to determine the potential effect of plasma on fungi colonizing winter wheat grain and the effect of this process on seed quality. The subject of our study was the winter wheat grain. The process of seed disinfection was conducted in a reactor with a packed-bed (wheat grain). The assessment of both the effectiveness of spore destruction and of seed quality were conducted...
Mountain pine (Pinus mugo) is the most important component of the sub−alpine and alpine zone in the Tatras, and other ranges of central Europe. In Poland, only population from the Karko− nosze Mts. has been studied in terms of phytopathological threats so far. There is not much information on the diseases caused by fungi in the mountain pine from other regions either. The mycological analyses of infected...
Celem artykułu jest przedstawienie stanu wiedzy nt. roli badań aeromikologicznych w górnictwie. Grzyby oraz ich metabolity wchodzące w skład tzw. bioareozolu mogą stanowić w odpowiednich warunkach zagrożenie dla zdrowia górników, a także maszyn i innych urządzeń wykorzystywanych pod ziemią. Do najczęściej występujących grzybów stwierdzanych w podziemiach (w tym także w kopalniach) należą grzyby z...
This paper reports on response time of mid-wavelength infrared nBn detector based on type-II 10 Monolayer/10 Monolayer InAs/GaSb superlattice structure with Al0.2Ga0.8Sb barrier. The detector structure is simulated with the numerical platform APSYS by Crosslight Inc. A detailed analysis of response time as a function of bias is performed and compared to experimental nBn detector results and PIN type-II...
