The Given

This paper investigates whether the combination of the addition of extracts derived from plants (plants derived extracts, PDE) to pork feedstuff and the meat conservation conditions (packaging and time exposure) affect consumers’ perception of pork quality, studied by means of visual appraisal, purchase intention and a home test. The three PDE groups were control, garlic extract and blended oil composed by carvacrol, timol, cynamic aldehide and eugenol extracts. Meat was packed in film, vacuum or modified atmosphere (MAP) packaging. A visual test was designed comprising a four-day storage step followed by a four-day exposure step in a refrigerated island display case. All studied effects influenced visual appraisal scores, being time exposure and packaging effects more noticeable than PDE or pig-sex effects. Meat from MAP scored higher than the rest. Scores decreased as exposure time increased, but this evolution was less perceptible in vacuum packaging and was faster for meat from the garlic group. Only gender affected the visual appraisal scores, with women scoring higher than men. Neither PDE addition nor pig sex affected to purchase intention whereas both exposure time and packaging type did. A maximum of 2 days of exposure would be recommended. In the home-test, meat from male pigs obtained higher scores than meat from female pigs, and none of the consumer-related effects influenced the given scores.

The Relationship

The article discusses the phenomenon of «perceptual trust» and its formation in micro intervals of time. The results of two empirical studies of trust’s perceptual estimates by human faces in various aspects of time exposure was revealed. In the first study, the following values of the time exposure used: 100,250 and 1000 ms. It is shown that the value for adequacy of perceptual trust are the highest exposure at 250 ms, and the least at 1000 ms. It is suggested that the evaluation of perceptual trust depends not only on the time of the demonstration of human facial expressions, sex, but also on the expression of human face. Wider range of exposure time values was used in the second study, 100, 300, 500, 1000 and 3000 to 1000 ms. As of stimulus images were made by representatives of persons Caucasoid, Mongoloid and Negroid racial groups. As the subjects were made by representatives of the Mongoloid racial group. The relationship between the adequacy of the perceptual trust evaluations and race of subjects and models are tested and evaluated models was revealed. The main result of the research can be considered a lack of empirical fixation unambiguous relationship between the level of trust in the person being evaluated and the duration of the perception of his face.

Abstract. In present study, the effect of irradiation along with applied load and three periods on the ultraviolet (UV) aging of the polycarbonate polymer was investigated by observing the changes in the mechanical properties. Dog bone specimens of polycarbonate were subjected to different test conditions namely in the amount of applied load and the variation in exposure time to the UV lamp. The results showed that, with a constant applied load of 1kN, increase in the exposure time in UV radiation caused the mechanical properties to relatively increase at first and decrease gradually afterwards. However, for constant exposure time, the tensile strength showed much decrease with increase in applied load. For the test conducted at higher applied load of 3kN, the mechanical properties of material relatively improves in a drastic manner for the higher exposure time. It was inferred that the increase in applied load has a crucial role in the UV aging of polycarbonate for the given exposure time. Moreover, the morphology of the fracture area under different test conditions was observed by Scanning Electron Microscope (SEM).
