Abstract

Helicopters are used in a variety of tasks like sea, mountain and land search and rescue, civil transportation or military operations. Their amount is growing, their ceiling is usually low, however, the exhaust emission from their engines is not restricted by any directive. That is why an attempt was made to determine the real exhaust emission. The research was done on the W-3 helicopter during the preflight engine run. Based on the results set the standard was created which reflects the working conditions of the engines during the test cycle. The research allowed to establish the unit emission of toxic gasses and then the influence on environment of the engines.

Abstract

The allergic reactions to fruits are lesser known among food sensitivities. The most common fruits belonging to the Rosaceae family that might cause allergic reactions are apples, pears and peaches. However, little is known about the potential allergic reactions caused by another member of the Rosaceae, the cherry. The aim of this study was to assess the risk of any allergic reaction or food hypersensitivity resulting from topical application and chronic oral administration of cherry fruits. The cherry fruits ‘Sabina’ cv. were produced in the orchard in Dąbrowice according to the principles of integrated (IFP) and organic (OR) productions. Fruits of ‘Debreceni Bötermö’ cv. were produced in Dąbrowice (IFP), and in the orchard in Nowy Dwór (OR). The experiments were performed on 65 outbred young, adult, white albinotic guinea pigs (Dankin Hartley). Three procedures were applied: I. Guinea-Pig Maximization Test (GPMT); II. Chronic administration of fruits and III. Skin prick (Dreborg) test. The skin reactions based on GPMT or Dreborg tests revealed no differences between the two cherry cultivars ‘Sabina’ and ‘Debreceni’ obtained from integrated or organic production. Similarly, it was not observed of any effect of cultivars of cherries nor the type of fruits production on the guinea pig skin reaction as a result of chronic feeding with fruits.
