Opis:
A vehicle ability to realise transport tasks may be restored by repairing only failed elements. This is called imperfect repair as the vehicle is not as good as new after such a repair. Preventive replacement is an example of imperfect repair as well. The advantage of such maintenance is that it enables controlling a reliability level of a fleet of vehicles. Sets of vehicles elements which should be replaced in that aim are derived on a base of statistical diagnosing with use of data about elements failures. The acceptable level of a failure risk while executing transportation tasks has been taken as a criterion. An algorithm for selecting elements for preventive replacement has been developed. It was shown that a level of a fleet reliability can be controlled by changing an order of a quantile function in coordination with a number of redundant objects. A computer simulation model of the vehicle fleet was used as an example to illustrate derived dependencies. In particular algorithm for selecting elements for preventive replacement, graph of model states, graphical interpretation of calculating new quantile orders, simulation experiments results for system n out of n, simulation experiments results for d = 2,5 are presented in the paper.

Opis:
An object ability to realise tasks may be restored by repairing only failed components. This is called imperfect repair as the object is not as good as new after such a repair. Preventive replacement is an example of imperfect repair as well. The advantage of such maintenance is that it enables controlling a reliability level of a system. Sets of objects’ components which should be replaced are derived on a basis of statistical diagnosing with use of data about components failures. The acceptable level of a failure risk while executing transportation tasks has been taken as a criterion of choosing elements to be replaced.

Opis:
Rodents, as mice and rats are the most common laboratory animals used in research and testing. They are seldom investigated for autochthonous ecto- and endoparasites prior their utilization in the experiments. Helminth parasites can alter the interpretation of final results. Pinworms commonly infecting laboratory rodents include mainly the mice pinworms Syphacia obvelata and Aspiculuris tetraptera, and in rats Syphacia muris. The fact that many laboratory rodent colonies were found to be parasite contaminated suggests a need for eradication and improvment of the quality of laboratory rodents. This review reports the data on the presence of helminth parasites in laboratory rodents colonies, and suggests to pay special attention on controlling the sanitary conditions of animal houses.

Opis:
Tortoises are a novelty in the world of pets. Although a great deal of information has been acquired on the internal medicine and surgery on these animals, little is known of their parasitological fauna. Fecal samples of 11 species of tortoises housed in the City Zoological Garden in Wroclaw were examined. Eggs of parasitic helminths were isolated using flotation and sedimentation techniques. The overall prevalence was 81.2%. Two groups (Nematoda and Trematoda) of endoparasites were found. Oxyurid eggs were found almost in every animal examined. Co-infection with oxyurids and ascarids was recorded for T. horsfieldii and T. marginata. Three species of tortoises were infected by digenic trematodes.
