Artykuł to kontynuacja prac, celem których jest poznanie rzeczywistych wibracji. Zawiera wyniki przeprowadzonych badań, obliczeń i analiz w zakresie wibracji występujących na elementach wyposażenia pojazdu gąsienicowego z grupy N10 oraz opancerzonego pojazdu kołowego z grupy N11 (klasyfikacje wg NO-06-A103:2005) wyposażonych w ręcznie sterowane systemy uzbrojenia. Szczegółowy opis przeprowadzonych analiz oraz wyniki badań w zakresie pojazdu grupy N10 zawarte są w artykule: „The Problem and Analysis of Vibrations Appearing in an N10 Group Military Vehicle Fitted with a Manually-Operated Armament Module” opublikowanym w kwartalniku Problems of Mechatronics Armament, Aviation, Safety Engineering. Niniejszy artykuł gruntownie prezentuje wyniki badań oraz ich analizy dla pojazdu grupy N11 i przywołuje jedynie wyniki analogicznych badań i analiz dla pojazdu grupy N10 w celu ich porównania. Przeprowadzone badania miały na celu zapoznanie się z charakterystyką drgań występujących na stabilizowanych systemach wieżowych (systemie uzbrojenia) oraz urządzeniach zasilających systemy wieżowe w aspekcie amplitud, wartości skutecznych oraz ich energii dla różnych warunków eksploatacji. Analizy przeprowadzono w odniesieniu do wymagań polskiej normy obronnej NO-06-A103:2005 oraz MIL-STD-810F w aspekcie słuszności ich stosowania.

This article is a continuation of work aimed to identify vibrations. It contains the results of tests, calculations, and analyses in the field of vibrations occurring on the elements of equipment of the N10 group tracked vehicle and the N11 group armored wheeled vehicle (classification according to NO-06-A103:2005) equipped with manually operated weapon systems. A detailed description of the analyses carried out, and the results of the research on the N10 group vehicle are contained in the article: "The Problem and Analysis of Vibrations Appearing in an N10 Group Military Vehicle Fitted with a Manually-Operated Armament Module" published in the quarterly Problems of Mechatronics Armament, Aviation, Safety Engineering. This study thoroughly presents the test results and their analysis for the N11 group vehicle and only recalls the results of similar tests and analyses for the N10 group vehicle for comparison. The research aimed to get acquainted with the characteristics of vibrations occurring in stabilized turret systems (weapon system) and devices supplying turret systems in terms of amplitudes, practical values, and their energy for various operating conditions. The analyses were carried out concerning the requirements of the Polish defense standard NO-06-A103:2005 and MIL-STD-810F regarding the correctness of their application.

Background. The aim of the study was to compare attitudes of children with hearing impair­ment towards dance lessons with the use of vibrating headphones, i.e. the Audiva High Pitch Training System to their attitudes towards physical education classes (PE) with elements of gymnastics, athletics, volleyball and basketball. Material and methods. The sample included 14 children aged 11.3 ± 1.0 years (min. 9 years, 8 months; max. 13 years, 5 months) with perceptive type of hearing impairment attending educational centers for deaf children in Poznan. The experimental group consisted of 8 female and 6 male pupils. Twice a week the children took part in dance lessons with the application of the Audiva High Pitch Training System – headphones which enable the subject to experience “bone hearing” through vibrations, and twice a week they attended PE classes. In order to measure the pupils attitudes towards PE lessons, the Baumgartner and Jackson Questionnaire was used. The measure­ments were made by single assessment of every type of PE classes (dance, gymnastics, athletics, volleyball and basketball). Results. Dance lessons with music and vibrating headphones had no higher emotional value for female students with hearing impairment than other types of PE classes. At the same time dance lessons were evaluated by girls as more intense and activating them more than the lessons of gymnastics. For male students dance lessons had lower emotional value than gymnastics, basketball and athletics. Boys also assessed dance lessons as less intense than the lessons of athletics. Conclusions. Obtained results proved that dance lessons had no higher emotional value for hearing-impaired children compared to other PE lessons. However, dance lessons with the use of vibrating headphones the Audiva High Pitch Trainig System may be a way to intensify PE for girls.

The expansion of the road network in Poland and in world constitutes a considerable risk for the natural environment, this article is showing the most important effects of road investments, for example: pollutants of atmospheric air, the noise and vibrations, pollutants of waters and soils, the fragmentation of the space and the decline of the landscape. Everything is leading it for destroying the environment in which we live. Describing all threats to the environment with themselves a structure and an exploitation of roads are bringing which, is practically impossible, the man in the last years very much is interfering in the nature, instead of to protect it for next generations, therefore designers and entrepreneurs should concentrate on eliminating negative effects of construction and the more late exploitation of roads and for improvement in their technical state.
